Description

Technical Field

[0001] The present application relates to the field of batteries, and in particular, to a coating device. Background Art

[0002] Batteries are widely used in the field of new energy, such as electric vehicles and new energy vehicles. New energy vehicles and electric vehicles have become a new trend in the development of the automotive industry. In the production process of batteries, it is necessary to coat the outer surface of the battery with an insulating film. The efficiency of the coating will affect the production efficiency of the battery. However, the efficiency of the coating is currently low. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a coating device, which aims to improve the problem of low coating efficiency in the related art.

[0004] An embodiment of the present application provides a film coating device, which includes a film preparation device, a cutting mechanism and a film coating device. The film preparation device includes a switching mechanism and multiple picking mechanisms. The multiple picking mechanisms are connected to the switching mechanism. The picking mechanism has a film preparation position and a film coating position. The switching mechanism is used to realize the switching of the picking mechanism between the film preparation position and the film coating position. The picking mechanism is used to pick up an insulating tape at the film preparation position; the cutting mechanism is used to cut the insulating tape to form an insulating film; and the film coating device is used to coat the insulating film picked up by the picking mechanism at the film coating position onto the outer surface of a workpiece.

[0005] In the above technical solution, when the coating device is working, multiple picking mechanisms switch between the film preparation position and the coating position in turn. When one picking mechanism is located at the coating position, other picking mechanisms can prepare the insulating film through the film preparation position. In this way, while the coating device is coating, the film preparation device starts to prepare the film. After the coating of the previous workpiece is completed, the coating of the next workpiece can be started immediately, and the original serial action is changed into parallel, thereby improving the efficiency of coating.

[0006] As an optional technical solution of an embodiment of the present application, the switching mechanism includes a first turret, and a plurality of the picking mechanisms are arranged on the first turret around a first axis. The first turret is configured to realize the switching of the picking mechanisms between the film preparation position and the film wrapping position when rotating around the first axis.

[0007] In the above technical solution, multiple picking mechanisms are arranged on the first turret, and as the first turret rotates, the multiple picking mechanisms reciprocate between the film coating position and the film preparation position in turn. By setting the first turret, the position switching of multiple picking mechanisms is simply and conveniently realized, with low cost and high stability.

[0008] As an optional technical solution of an embodiment of the present application, the film wrapping equipment includes a plurality of cutting mechanisms, and the plurality of cutting mechanisms are arranged on the first turret and can rotate with the first turret, and the cutting mechanisms correspond one-to-one to the picking mechanisms.

[0009] In the above technical solution, a plurality of cutting mechanisms and picking mechanisms are arranged in one-to-one correspondence. When the first turret rotates, the cutting mechanism and the picking mechanism both rotate with the first turret, and the relative positions of the cutting mechanism and the picking mechanism remain unchanged. As the first turret rotates, the insulating tape picked up by the picking mechanism gradually increases. When the length of the insulating tape meets the requirements, the cutting mechanism cuts the insulating tape to form an insulating film.

[0010] As an optional technical solution of an embodiment of the present application, the picking mechanism includes an adsorption member provided with suction holes, and the adsorption member is used to adsorb the insulating tape.

[0011] In the above technical solution, by arranging an adsorption member to adsorb the insulating material tape, the adsorption member is not easy to cause damage to the insulating material tape. In this way, the insulating film cut by the cutting mechanism has better quality, which is beneficial to improving the coating effect.

[0012] As an optional technical solution of an embodiment of the present application, the film preparation device includes a pressing mechanism, and the pressing mechanism is used to press the insulating material tape onto the adsorption member.

[0013] In the above technical solution, a pressing mechanism is provided to press the insulating tape against the adsorption member, thereby reducing the risk of the insulating tape accidentally detaching from the adsorption member and improving the stability of the operation of the coating equipment.

[0014] As an optional technical solution of the embodiment of the present application, the clamping mechanism corresponds one-to-one with the adsorption member.

[0015] In the above technical solution, the clamping mechanism and the adsorbent are arranged in a one-to-one correspondence, so that the insulating tape adsorbed by each adsorbent can be clamped by the corresponding clamping mechanism, reducing the risk of the insulating tape detaching from the adsorbent. The clamping mechanism and the adsorbent can both be arranged on the first turret, so that the clamping mechanism and the adsorbent can rotate with the first turret, and the relative position of the clamping mechanism and the adsorbent remains unchanged. In this way, before the adsorbent reaches the coating position, the insulating tape or the insulating film can be clamped on the adsorbent, so that the insulating tape or the insulating film is not easy to detach from the adsorbent. In addition, since the relative position of the clamping mechanism and the adsorbent remains unchanged, when the clamping mechanism clamps the insulating tape or the insulating film, it is not easy to cause damage to the insulating tape or the insulating film.

[0016] As an optional technical solution of an embodiment of the present application, the switching mechanism includes a first turret, the adsorption member is connected to the first turret, and the first turret is configured to realize the switching of the adsorption member between the film preparation position and the film wrapping position when rotating around a first axis; the clamping mechanism includes a rocker arm, a clamping member and a first driving mechanism, the rocker arm is rotatably arranged on the first turret around a second axis, and the second axis intersects with the first axis; the clamping member is arranged on the rocker arm; the first driving mechanism is connected to the rocker arm and the first turret, and the first driving mechanism is used to drive the rocker arm to swing around the second axis so that the clamping member presses the insulating material tape against the adsorption member.

[0017] In the above technical solution, the clamping member is connected to the rocker arm, and the first driving mechanism can drive the rocker arm to swing, so that the clamping member is close to the adsorption member to press the insulating material strip against the adsorption member; or the clamping member is away from the adsorption member to loosen the insulating film, thereby facilitating the coating device to coat.

[0018] As an optional technical solution of the embodiment of the present application, the pressing member is a roller.

[0019] In the above technical solution, by using a roller as a pressing member, on the one hand, when the insulating material strip and the pressing member move relative to each other, rolling friction is formed between the pressing member and the insulating material strip, and the friction resistance is small, and it is not easy to damage the insulating material strip. On the other hand, the peripheral surface of the roller is generally soft and elastic, and it is not easy to damage the insulating material strip when it contacts with the insulating material strip.

[0020] As an optional technical solution of an embodiment of the present application, the coating device includes a coating mechanism, and the coating mechanism is used to drive the workpiece to rotate around its own axis so that the insulating film is coated on the outer surface of the workpiece.

[0021] In the above technical solution, one side of the insulating film is sticky. When coating, the insulating film picked up by the pickup mechanism located at the coating position can contact the workpiece, thereby adhering to the workpiece. The coating mechanism drives the workpiece to rotate around its own axis, thereby gradually winding the insulating film and adhering it to the outer surface of the workpiece. This coating method has a fast coating speed and high efficiency.

[0022] As an optional technical solution of an embodiment of the present application, the coating device includes a second turret and a plurality of the coating mechanisms, wherein the plurality of the coating mechanisms are arranged on the second turret around a third axis, and the second turret is configured to switch the coating mechanism to a working position when rotating around the third axis, and the coating mechanism is used to coat the insulating film on the outer surface of the workpiece at the working position.

[0023] In the above technical solution, one coating mechanism can coat one workpiece, and multiple coating mechanisms are arranged on the second turret. As the second turret rotates, multiple coating mechanisms are switched to working positions in sequence. In this way, after the coating of the previous workpiece is completed, the coating of the next workpiece can be started immediately, and the original serial actions are changed to parallel actions, thereby improving the coating efficiency.

[0024] As an optional technical solution of an embodiment of the present application, the second turret includes a support table for placing a support cup, the support cup is used to accommodate the workpiece, and a lifting mechanism is provided on the support table, the lifting mechanism is used to lift the workpiece to separate the workpiece from the support cup and transfer it to the coating mechanism.

[0025] In the above technical solution, by placing the workpiece in the support cup, the workpiece can be protected and the damage to the workpiece during transportation can be reduced. By setting a lifting mechanism, when the workpiece needs to be coated, the workpiece is pushed out of the support cup and transferred to the coating mechanism, so that the coating mechanism drives the workpiece to rotate, thereby coating the insulating film on the outer surface of the workpiece.

[0026] As an optional technical solution of the embodiment of the present application, a plurality of first snap-in sockets are arranged on the outer peripheral surface of the support platform, and the plurality of first snap-in sockets are arranged around the third axis, and the first snap-in sockets are used to accommodate the support cup.

[0027] In the above technical solution, multiple first bayonet holes are arranged on the outer peripheral surface of the support table, each of which can accommodate a support cup. As the second turret rotates, the first bayonet holes pass through the working position in sequence, thereby transferring the support cup to the working position. Afterwards, the lifting mechanism and the coating mechanism can drive the workpiece to rotate so as to coat the insulating film on the workpiece.

[0028] As an optional technical solution of an embodiment of the present application, the coating device includes a first retaining member, which is arranged around the outer side of the support platform, and the first retaining member is used to retain the support cup in the first clamping portion. The retaining member includes a first feed end and a first discharge end, and the support platform is configured to transport the support cup from the first feed end to the first discharge end.

[0029] In the above technical solution, by providing the first retaining member, the support cup is retained in the first bayonet during the rotation of the support member. The support cup enters the first bayonet from the first feeding end, passes through the working position as the support seat rotates, and is discharged from the first discharging end. During the whole process, the support cup is not easy to be separated from the first bayonet, thereby improving the stability of the coating device.

[0030] As an optional technical solution of an embodiment of the present application, the coating mechanism includes a clamping member and a second driving mechanism, the clamping member is arranged opposite to the lifting mechanism, and the clamping member is used to cooperate with the lifting mechanism to clamp the workpiece; the second driving mechanism connects the second turret and the clamping member, and the second driving mechanism is used to drive the clamping member to rotate so as to realize the rotation of the workpiece around its own axis.

[0031] In the above technical solution, the lifting mechanism lifts the workpiece so that after the workpiece is separated from the support cup, one end of the workpiece can contact the clamping member, so that the lifting mechanism and the clamping member cooperate to clamp the workpiece. The second driving mechanism can drive the clamping member to rotate, thereby driving the workpiece to rotate around its own axis, so that the insulating film is coated on the outer surface of the workpiece.

[0032] As an optional technical solution of an embodiment of the present application, the clamping member includes a mounting portion, a clamping portion and an elastic portion, the mounting portion is connected to the second driving mechanism; the clamping portion is used to cooperate with the lifting mechanism to clamp the workpiece; the elastic portion is arranged between the mounting portion and the clamping portion.

[0033] In the above technical solution, when the lifting mechanism lifts the workpiece off the support cup, the workpiece contacts the clamping portion and compresses the elastic portion, so that the workpiece can be clamped between the clamping portion and the lifting mechanism. The provision of the elastic portion makes the clamping piece have a certain flexibility, and the workpiece is not easily damaged during the clamping process.

[0034] As an optional technical solution of an embodiment of the present application, the coating device includes a holding mechanism, which is arranged on the support platform and is used to hold the workpiece between the lifting mechanism and the coating mechanism.

[0035] In the above technical solution, a holding mechanism is provided to hold the workpiece between the lifting mechanism and the coating mechanism. During the rotation of the workpiece, the workpiece is not easy to separate from between the lifting mechanism and the coating mechanism, which is beneficial to improving the coating stability of the coating equipment and ensuring the coating efficiency to a certain extent.

[0036] As an optional technical solution of an embodiment of the present application, the holding mechanism includes a mounting seat and a limiting roller, the mounting seat is arranged on the support platform, the limiting roller is rotatably arranged on the mounting seat, the limiting roller is used to contact the workpiece, and the limiting roller is configured to rotate around its own axis when the coating mechanism drives the workpiece to rotate.

[0037] In the above technical solution, when the coating mechanism drives the workpiece to rotate around its own axis, the limiting roller can contact the outer peripheral surface of the workpiece, thereby rotating with the rotation of the workpiece to achieve the effect of limiting the detachment of the workpiece.

[0038] As an optional technical solution of an embodiment of the present application, the holding mechanism includes a plurality of limiting rollers arranged around the workpiece.

[0039] In the above technical solution, by setting a plurality of limiting rollers, the limiting effect is better, which is beneficial to improving the stability of the film coating of the coating equipment and ensuring the efficiency of the film coating to a certain extent.

[0040] As an optional technical solution of an embodiment of the present application, the coating device includes a smoothing mechanism, the smoothing mechanism includes a smoothing member, and the smoothing member is configured to abut against the insulating film coated on the workpiece when the workpiece rotates following the second turret.

[0041] In the above technical solution, a smoothing piece is provided to smooth the insulating film coated on the workpiece, thereby reducing the risk of wrinkling of the insulating film and improving the quality of the coating.

[0042] As an optional technical solution of an embodiment of the present application, the smoothing mechanism also includes a third driving mechanism, which is connected to the smoothing member and configured to adjust the distance between the smoothing member and the second turret in the radial direction of the second turret.

[0043] In the above technical solution, as the number of layers of the insulating film coated on the workpiece increases, the force between the workpiece and the smoothing member increases. By setting a third driving mechanism to adjust the radial position of the smoothing member on the second turret, the smoothing member can always be in contact with the insulating film on the workpiece before the insulating film coating is completed, which neither applies a large external force to the workpiece to allow the workpiece to separate from the coating mechanism and the lifting mechanism, but can also smooth the insulating film.

[0044] As an optional technical solution of an embodiment of the present application, the film wrapping equipment includes a plurality of unwinding mechanisms, wherein the unwinding mechanisms are used to unwind the insulating material tape, and the plurality of unwinding mechanisms selectively provide the insulating material tape to the picking mechanism.

[0045] In the above technical solution, the unwinding mechanism can unwind the insulating tape, thereby providing the insulating tape to the picking mechanism. By providing multiple unwinding mechanisms, the multiple unwinding mechanisms selectively provide the insulating tape to the picking mechanism, so that when the insulating tape of one unwinding mechanism is exhausted, other unwinding mechanisms can be switched to continue to provide the insulating tape to the picking mechanism, thereby reducing downtime and improving film coating efficiency.

[0046] As an optional technical solution of an embodiment of the present application, the unwinding mechanism includes an unwinding roller, a fixed frame, a movable frame and a fourth driving mechanism, the unwinding roller is used to unwind the insulating tape; the unwinding roller is arranged on the fixed frame; the movable frame is provided with a guide, the guide is used to guide the insulating tape to the picking mechanism, and the movable frame is slidably connected to the fixed frame; the fourth driving mechanism is connected to the fixed frame and the movable frame, and the fourth driving mechanism is used to drive the movable frame to slide relative to the fixed frame so that the guide is close to or away from the picking mechanism.

[0047] In the above technical solution, by slidably connecting the movable frame with the fixed frame, the fourth driving mechanism can drive the movable frame to approach the pick-up mechanism relative to the fixed frame, so that the insulating tape unwound by the unwinding roller can approach the pick-up mechanism after passing through the guide, thereby providing the insulating tape to the pick-up mechanism. The fourth driving mechanism can also drive the movable frame to move away from the pick-up mechanism relative to the fixed frame, thereby stopping providing the insulating tape to the pick-up mechanism.

[0048] As an optional technical solution of an embodiment of the present application, the unwinding mechanism further includes a film pressing mechanism, and the film pressing mechanism is used to press the insulating material tape led out by the guide member onto the picking mechanism.

[0049] In the above technical solution, a film pressing mechanism is provided to press the insulating tape led out by the guide onto the picking mechanism, so that the unwinding mechanism can provide the insulating tape to the picking mechanism more stably, reducing the risk of shutdown due to feed interruption, and ensuring the efficiency of film coating to a certain extent.

[0050] As an optional technical solution of an embodiment of the present application, the unwinding mechanism includes a first roller and a second roller, the first roller is arranged on a fixed frame, the second roller is arranged on a movable frame, the insulating tape is wound around the first roller and the second roller, and the unwinding mechanism also includes a clamping mechanism, the clamping mechanism is arranged upstream of the first roller, and the clamping mechanism is used to clamp or loosen the insulating tape.

[0051] In the above technical solution, before the film coating equipment works, the insulating tape needs to be placed on the unwinding roller and passed through the first over-roller, the second over-roller and the guide piece in sequence, so as to prepare to feed the pick-up mechanism. When the insulating tape on the unwinding roller is exhausted, the other unwinding mechanism is switched to feed the pick-up mechanism, and then the insulating tape upstream of the clamping mechanism is manually cut off to facilitate replacement with a new insulating tape. The new insulating tape is engaged with the old insulating tape clamped by the clamping mechanism, and the installation of the new insulating tape can be completed without having to pass through the first over-roller, the second over-roller and the guide piece in sequence, which increases the convenience of replacing the insulating tape.

[0052] As an optional technical solution of an embodiment of the present application, the coating device also includes a detection mechanism and a waste collection device, the detection mechanism is used to detect the insulating film; the waste collection device is electrically connected to the detection mechanism, and the waste collection device responds to the detection mechanism to peel the insulating film off the picking mechanism.

[0053] In the above technical solution, the detection mechanism can detect the insulating film. When the detection mechanism detects that the insulating film is wrinkled or has other problems, the waste collection device will peel off the problematic insulating film and pick it up, thereby reducing the risk of wrapping the problematic insulating film onto the workpiece and ensuring the quality of the coating to a certain extent.

[0054] As an optional technical solution of an embodiment of the present application, the waste collecting device includes a winding member, and the winding member is used to contact the insulating film and wind the insulating film.

[0055] In the above technical solution, when the detection mechanism detects that the insulating film is wrinkled or has other problems, the winding member of the waste collection device can contact the insulating film, and the insulating film can be adhered to the winding member, thereby rolling up the insulating film to peel off the insulating film from the picking mechanism, which is simple and convenient.

[0056] As an optional technical solution of an embodiment of the present application, the waste collecting device also includes a fifth driving mechanism, which is connected to the winding member and is used to drive the winding member to rotate so that the insulating film is wound around the winding member.

[0057] In the above technical solution, the fifth driving mechanism is provided to drive the winding member to actively rotate, so that the insulating film can be more conveniently rolled onto the winding member.

[0058] As an optional technical solution of an embodiment of the present application, the waste collecting device further includes a sixth driving mechanism, which is connected to the winding member and is used to drive the winding member to approach or move away from the picking mechanism.

[0059] In the above technical solution, as the winding member continuously rewinds the problematic insulating film, the insulating film on the winding member gradually increases, and the overall diameter of the winding member increases. In order to reduce the stress of the winding member on the pickup mechanism, the sixth driving mechanism can adjust the distance between the winding member and the pickup mechanism, so that the winding member can approach the pickup mechanism to rewind the problematic insulating film, and control the distance from the pickup mechanism during rewinding, thereby reducing the stress on the pickup mechanism. In addition, when the insulating film does not need to be rewound, the sixth driving mechanism can drive the winding member away from the pickup mechanism, thereby reducing the risk of interference with the pickup mechanism.

The material of the negative electrode current collector may be copper, and the negative electrode active material may be carbon or silicon, etc. In order to ensure that a large current can pass without melting, the number of positive pole ears is multiple and stacked together, and the number of negative pole ears is multiple and stacked together. The material of the isolation film may be PP (polypropylene) or PE (polyethylene), etc. In addition, the electrode assembly may be a winding structure or a laminated structure, and the embodiments of the present application are not limited thereto.

[0091] At present, from the perspective of market development, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0092] During the production of batteries, an insulating film needs to be coated on the outer surface of the battery. The efficiency of the coating will affect the production efficiency of the battery. However, the efficiency of the coating is currently low.

[0093] In the prior art, when coating the outer surface of a battery with an insulating film, generally, the insulating film is prepared first, and then coated on the workpiece. In the process of coating the insulating film on the workpiece, a new insulating film cannot be prepared in advance, and the new insulating film can only be prepared again after the insulating film coating is completed. This serial production method has a low coating efficiency.

[0094] In view of this, an embodiment of the present application provides a film coating device, which includes a film preparation device, a cutting mechanism and a film coating device. The film preparation device includes a switching mechanism and a plurality of picking mechanisms, and the plurality of picking mechanisms are connected to the switching mechanism. The picking mechanism has a film preparation position and a film coating position, and the switching mechanism is used to realize the switching of the picking mechanism between the film preparation position and the film coating position, and the picking mechanism is used to pick up the insulating tape at the film preparation position. The cutting mechanism is used to cut the insulating tape to form an insulating film. The film coating device is used to coat the insulating film picked up by the picking mechanism at the film coating position on the outer surface of the workpiece.

[0095] When the coating device is working, multiple picking mechanisms switch between the film preparation position and the coating position in turn. When one picking mechanism is at the coating position, other picking mechanisms can prepare the insulating film at the coating preparation position. In this way, while the coating device is coating, the film preparation device starts to prepare the film. After the coating of the previous workpiece is completed, the coating of the next workpiece can be started immediately, turning the originally serial actions into parallel actions, thereby improving the efficiency of coating.

[0096] The technical solution described in the embodiment of the present application is suitable for coating an insulating film on a workpiece, and the workpiece may be a battery (especially suitable for cylindrical batteries). The use of this coating equipment can improve the coating efficiency.

[0097] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 A schematic structural diagram of a coating device 10 provided in some embodiments of the present application. Figure 2 A schematic structural diagram of a film preparation device 11 provided in some embodiments of the present application. Figure 3 for Figure 2 Enlarged view of position A in the middle. Figure 4 A schematic diagram of the cooperation between a film preparation device 11 and a film wrapping device 12 provided for some embodiments of the present application. An embodiment of the present application provides a film wrapping device 10, which includes a film preparation device 11, a cutting mechanism 19 and a film wrapping device 12. The film preparation device 11 includes a switching mechanism 112 and a plurality of picking mechanisms 111, and the plurality of picking mechanisms 111 are connected to the switching mechanism 112. The picking mechanism 111 has a film preparation position and a film wrapping position, and the switching mechanism 112 is used to realize the switching of the picking mechanism 111 between the film preparation position and the film wrapping position. The picking mechanism 111 is used to pick up an insulating tape 23 at the film preparation position. The cutting mechanism 19 is used to cut the insulating tape 23 to form an insulating film. The film wrapping device 12 is used to wrap the insulating film picked up by the picking mechanism 111 at the film wrapping position on the outer surface of the workpiece 22.

[0098] The picking mechanism 111 is a mechanism for picking up the insulating material tape 23. The picking mechanism 111 can be a clamping mechanism, a vacuum adsorption mechanism, etc. The picking mechanism 111 has a film preparation position and a film coating position. When the picking mechanism 111 is in the film preparation position, the picking mechanism 111 can pick up the insulating material tape 23. When the picking mechanism 111 is in the film coating position, the picking mechanism 111 can cooperate with the film coating device 12 to coat the insulating film on the outer surface of the workpiece 22.

[0099] The switching mechanism 112 is used to drive the picking mechanism 111 to move, so as to switch the picking mechanism 111 between the film preparation position and the film coating position. The switching mechanism 112 can be directly connected to the picking mechanism 111, or can be indirectly connected to the picking mechanism 111. For example, the switching mechanism 112 can be indirectly connected to the picking mechanism 111 through an intermediate component.

[0100] The film preparation device 11 includes a plurality of picking mechanisms 111, and the plurality of picking mechanisms 111 are all connected to a switching mechanism 112. The switching mechanism 112 can realize the reciprocating motion of the plurality of picking mechanisms 111, so that each picking mechanism 111 is switched between the film preparation position and the film coating position.

[0101] The switching mechanism 112 can be a moving mechanism that drives the picking mechanism 111 to move, so as to drive the picking mechanism 111 to move back and forth between the film preparation position and the film coating position. The switching mechanism 112 can also be a rotating mechanism that drives the picking mechanism 111 to rotate, so as to drive the picking mechanism 111 to rotate between the film preparation position and the film coating position.

[0102] The cutting mechanism 19 is a mechanism for cutting the insulating tape 23 to form an insulating film. When the picking mechanism 111 switches from the film preparation position to the film coating position, the cutting mechanism 19 cuts the insulating tape 23, and the picking mechanism 111 keeps picking up the cut portion of the insulating tape 23 (insulating film) to transport the insulating film to the film coating position. The cutting mechanism 19 may include a cutter and a driving mechanism, and the driving mechanism drives the cutter to approach the insulating tape 23, thereby cutting the insulating tape 23.

[0103] The film coating device 12 is a device for coating an insulating film on the outer surface of the workpiece 22. Optionally, the film coating device 12 includes a plurality of film coating jaws, and the plurality of film coating jaws wrap the insulating film around the outer surface of the workpiece 22.

[0104] When the coating device 10 is working, a plurality of picking mechanisms 111 are switched between the film preparation position and the coating position in turn. When one picking mechanism 111 is located at the coating position, other picking mechanisms 111 can prepare the insulating film at the coating preparation position. In this way, while the coating device 12 is coating, the film preparation device 11 starts to prepare the film. After the coating of the previous workpiece 22 is completed, the coating of the next workpiece 22 can be started immediately, and the originally serial actions are changed into parallel actions, thereby improving the efficiency of coating.

[0105] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the switching mechanism 112 includes a first turret 1121, and a plurality of picking mechanisms 111 are disposed around a first axis on the first turret 1121. The first turret 1121 is configured to switch the picking mechanisms 111 between the film preparation position and the film encapsulation position when rotating around the first axis.

[0106] The first axis is the rotation axis of the first turret 1121. The first turret 1121 is a rotating body that can rotate around the first axis. “Multiple picking mechanisms 111 are arranged on the first turret 1121 around the first axis” can also be understood as multiple picking mechanisms 111 are arranged on the first turret 1121 along the circumference of the first turret 1121.

[0107] When the first turret 1121 rotates around the first axis, it can drive the multiple picking mechanisms 111 to rotate, so that each picking mechanism 111 can be switched between the film preparation position and the film wrapping position.

[0108] Multiple picking mechanisms 111 are arranged on the first turret 1121. As the first turret 1121 rotates, the multiple picking mechanisms 111 reciprocate between the film coating position and the film preparation position in turn. By setting the first turret 1121, the position switching of the multiple picking mechanisms 111 is realized simply and conveniently, with low cost and high stability.

[0109] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the film encapsulating device 10 includes a plurality of cutting mechanisms 19, which are disposed on the first turret 1121 and can rotate along with the first turret 1121. The cutting mechanisms 19 correspond to the picking mechanisms 111 one by one.

[0110] The film coating device 12 may include one picking mechanism 111, two picking mechanisms 111, three picking mechanisms 111, or more than three picking mechanisms 111. Correspondingly, the film coating device 10 may include one cutting mechanism 19, two cutting mechanisms 19, three cutting mechanisms 19, or more than three cutting mechanisms 19. The number of the cutting mechanisms 19 is equal to the number of the picking mechanisms 111, and is arranged corresponding to the picking mechanisms 111.

[0111] The plurality of cutting mechanisms 19 may be arranged around the first axis on the first turret 1121, so as to rotate with the first turret 1121. The plurality of cutting mechanisms 19 are arranged in one-to-one correspondence with the picking mechanism 111. When the first turret 1121 rotates, the cutting mechanism 19 and the picking mechanism 111 both rotate with the first turret 1121, and the relative positions of the cutting mechanism 19 and the picking mechanism 111 remain unchanged. As the first turret 1121 rotates, the insulating tape 23 picked up by the picking mechanism 111 gradually increases. When the length of the insulating tape 23 meets the requirements, the cutting mechanism 19 cuts the insulating tape 23, so as to form an insulating film.

[0112] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the picking mechanism 111 includes a suction member 1111 provided with suction holes 11111 , and the suction member 1111 is used to adsorb the insulating tape 23 .

[0113] The picking mechanism 111 is a vacuum adsorption mechanism, which includes an adsorption member 1111 in contact with the insulating tape 23, and an air suction hole 11111 is provided on the adsorption member 1111. The air suction hole 11111 generates negative pressure by suction, thereby picking up the insulating tape 23 under the action of the pressure difference.

[0114] By arranging the adsorption member 1111 to adsorb the insulating material tape 23, the adsorption member 1111 is not easy to cause damage to the insulating material tape 23. In this way, the insulating film cut out by the cutting mechanism 19 has better quality, which is beneficial to improving the coating effect.

[0115] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the film preparation device 11 includes a pressing mechanism 113 , and the pressing mechanism 113 is used to press the insulating tape 23 onto the adsorption member 1111 .

[0116] The pressing mechanism 113 is a mechanism for pressing the insulating material strip 23 against the adsorbent 1111. For example, the pressing mechanism 113 may include a linear drive and a pressing member 1132, wherein the linear drive is connected to the pressing member 1132, and the linear drive drives the pressing member 1132 to approach the adsorbent 1111, thereby pressing the insulating material strip 23 against the adsorbent 1111.

[0117] By providing a pressing mechanism 113 , the insulating tape 23 is pressed against the adsorption member 1111 , thereby reducing the risk of the insulating tape 23 accidentally detaching from the adsorption member 1111 , and improving the operating stability of the coating device 10 .

[0118] In some embodiments, the clamping mechanism 113 corresponds to the adsorption member 1111 one by one.

[0119] The number of the clamping mechanisms 113 and the adsorption members 1111 is the same, and the clamping mechanisms 113 are arranged corresponding to the adsorption members 1111 , so as to facilitate the compression of the insulating tape 23 onto the adsorption members 1111 .

[0120] The clamping mechanism 113 and the adsorbent 1111 are arranged in a one-to-one correspondence, so that the insulating tape 23 adsorbed by each adsorbent 1111 can be clamped by the corresponding clamping mechanism 113, reducing the risk of the insulating tape 23 being separated from the adsorbent 1111. The clamping mechanism 113 and the adsorbent 1111 can both be arranged on the first turret 1121, so that the clamping mechanism 113 and the adsorbent 1111 can both rotate with the first turret 1121, and the relative position of the clamping mechanism 113 and the adsorbent 1111 remains unchanged. In this way, before the adsorbent 1111 reaches the film coating position, the insulating tape 23 or the insulating film can be clamped on the adsorbent 1111, so that the insulating tape 23 or the insulating film is not easy to be separated from the adsorbent 1111. In addition, since the relative position of the clamping mechanism 113 and the adsorbent 1111 remains unchanged, when the clamping mechanism 113 clamps the insulating tape 23 or the insulating film, it is not easy to cause damage to the insulating tape 23 or the insulating film.

[0121] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4In some embodiments, the switching mechanism 112 includes a first turret 1121, the adsorbent 1111 is connected to the first turret 1121, and the first turret 1121 is configured to switch the adsorbent 1111 between the film preparation position and the film coating position when rotating around the first axis. The clamping mechanism 113 includes a swing rod 1131, a clamping member 1132 and a first driving mechanism 1133, the swing rod 1131 is rotatably arranged on the first turret 1121 around a second axis, and the second axis intersects the first axis. The clamping member 1132 is arranged on the swing rod 1131. The first driving mechanism 1133 is connected to the swing rod 1131 and the first turret 1121, and the first driving mechanism 1133 is used to drive the swing rod 1131 to swing around the second axis, so that the clamping member 1132 presses the insulating tape 23 against the adsorbent 1111.

[0122] The adsorption member 1111 is disposed on the outer periphery of the first turret 1121 , so as to rotate along with the first turret 1121 when the first turret 1121 rotates, so as to switch between the film preparation position and the film encapsulation position.

[0123] The swing rod 1131 is a component that can swing relative to the first turret 1121. The swing rod 1131 is rotatably disposed on the first turret 1121 around a second axis. The second axis may be at an acute angle to the first axis, or may be perpendicular to the first axis.

[0124] The pressing member 1132 and the first driving mechanism 1133 can be respectively arranged at the two ends of the swing rod 1131. When the first driving mechanism 1133 drives the swing rod 1131 to swing, the pressing member 1132 can approach or move away from the adsorption member 1111. Figure 3 ,exist Figure 3 In the illustrated embodiment, when the first driving mechanism 1133 drives the swing rod 1131 upward to swing, the pressing member 1132 moves downward, thereby pressing the insulating tape 23 against the adsorption member 1111. When the first driving mechanism 1133 drives the swing rod 1131 downward to swing, the pressing member 1132 moves upward, thereby releasing the insulating tape 23.

[0125] The first driving mechanism 1133 may include a linear driving member, which is connected to the swing rod 1131. The linear driving member outputs linear motion, thereby driving the swing rod 1131 to swing, so that the pressing member 1132 is close to or away from the adsorption member 1111. The linear driving member may be a linear electric cylinder, a linear oil cylinder, a linear air cylinder, etc. The first driving mechanism 1133 may also include a rotating driving member and a transmission mechanism, and the rotating driving member is connected to the swing rod 1131 through the transmission mechanism. The rotating driving member outputs rotational motion, and the transmission mechanism converts the rotational motion into the swing of the swing rod 1131, so that the pressing member 1132 is close to or away from the adsorption member 1111. The rotating driving member may be a motor, an internal combustion engine, a rotating handle, etc. The transmission mechanism may be a screw nut mechanism, a crank slider mechanism, etc.

[0126] Optionally, the first driving mechanism 1133 may include a cam and a lifting rod, one end of the lifting rod is in contact with the cam, and the other end of the lifting rod is hinged to the swing rod 1131. The cam is rotatably disposed on the first turret 1121. When the cam rotates, the lifting rod rises or falls under the action of the cam, thereby driving the swing rod 1131 to swing.

[0127] The clamping member 1132 is connected to the rocker arm 1131, and the first driving mechanism 1133 can drive the rocker arm 1131 to swing, so that the clamping member 1132 is close to the adsorption member 1111 to press the insulating tape 23 against the adsorption member 1111; or the clamping member 1132 is away from the adsorption member 1111 to loosen the insulating film, thereby facilitating the coating device 12 to coat.

[0128] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the pressing member 1132 is a roller.

[0129] By using a roller as the pressing member 1132, on the one hand, when the insulating material tape 23 and the pressing member 1132 move relative to each other, rolling friction is formed between the pressing member 1132 and the insulating material tape 23, and the friction resistance is small, which is not easy to damage the insulating material tape 23. On the other hand, the peripheral surface of the roller is generally soft and elastic, and it is not easy to damage the insulating material tape 23 when it contacts with the insulating material tape 23.

[0130] Please refer to Figure 1 , Figure 4 and Figure 5 , Figure 5 The schematic diagram of the structure of the coating device 12 provided in some embodiments of the present application. In some embodiments, the coating device 12 includes a coating mechanism 121, which is used to drive the workpiece 22 to rotate around its own axis so that the insulating film is coated on the outer surface of the workpiece 22.

[0131] The insulating tape 23 or the insulating film may have a sticky or adhesive layer so that the insulating film can be bonded to the outer surface of the workpiece 22 .

[0132] The coating mechanism 121 is a mechanism for driving the workpiece 22 to rotate around its own axis. When the insulating film is bonded to the outer surface of the workpiece 22, the coating mechanism 121 drives the workpiece 22 to rotate around its own axis, so that the insulating film is wrapped around the outer surface of the workpiece 22 to complete the coating.

[0133] One side of the insulating film is sticky, and during coating, the insulating film picked up by the pick-up mechanism 111 located at the coating position can contact the workpiece 22, thereby being bonded to the workpiece 22. The coating mechanism 121 drives the workpiece 22 to rotate around its own axis, thereby gradually winding the insulating film and bonding it to the outer surface of the workpiece 22. This coating method has a fast coating speed and high efficiency.

[0134] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the coating device 12 includes a second turret 122 and a plurality of coating mechanisms 121, and the plurality of coating mechanisms 121 are disposed on the second turret 122 around a third axis. The second turret 122 is configured to switch the coating mechanisms 121 to a working position when rotating around the third axis, and the coating mechanisms 121 are used to coat the outer surface of the workpiece 22 with an insulating film at the working position.

[0135] The third axis is the rotation axis of the second turret 122. The second turret 122 is a rotating body that can rotate around the third axis. "Multiple film coating mechanisms 121 are arranged on the second turret 122 around the third axis" can also be understood as multiple film coating mechanisms 121 are arranged on the second turret 122 along the circumference of the second turret 122.

[0136] When the second turret 122 rotates around the third axis, it can drive the plurality of film wrapping mechanisms 121 to rotate, so that each film wrapping mechanism 121 cycles through the working position in sequence.

[0137] When the coating mechanism 121 passes the working position, the workpiece 22 can contact the insulating film picked up by the picking mechanism 111 at the coating position. As the coating mechanism 121 drives the workpiece 22 to rotate, the insulating film is coated on the outer surface of the workpiece 22 .

[0138] One coating mechanism 121 can coat one workpiece 22. Multiple coating mechanisms 121 are arranged on the second turret 122. As the second turret 122 rotates, multiple coating mechanisms 121 are switched to working positions in sequence. In this way, after the coating of the previous workpiece 22 is completed, the coating of the next workpiece 22 can be started immediately, and the original serial actions are changed to parallel actions, thereby improving the coating efficiency.

[0139] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the second turret 122 includes a support table 1221 for placing a support cup 21, and the support cup 21 is used to accommodate the workpiece 22. A lifting mechanism 123 is provided on the support table 1221, and the lifting mechanism 123 is used to lift the workpiece 22 to separate the workpiece 22 from the support cup 21 and transfer it to the coating mechanism 121.

[0140] The support cup 21 is a cup structure for accommodating the workpiece 22. The lower end of the support cup 21 is provided with a through hole for the lifting mechanism 123 to extend into, and the upper end of the support cup 21 is provided with an opening for the workpiece 22 to enter and leave the support cup 21. A flange can be formed on the inner side of the support cup 21 to support the workpiece 22 and reduce the risk of friction between the workpiece 22 and the outside world.

[0141] The support platform 1221 can support the support cup 21 and drive the support cup 21 to rotate. The lifting mechanism 123 is arranged on the support platform 1221, and the lifting mechanism 123 can lift the workpiece 22, so that the workpiece 22 is separated from the support cup 21, so that the insulating film is coated on the workpiece 22. After the workpiece 22 is separated from the support cup 21, it can cooperate with the coating mechanism 121, so that it rotates around its own axis under the drive of the coating mechanism 121.

[0142] By placing the workpiece 22 in the support cup 21, the workpiece 22 can be protected and the damage to the workpiece 22 during transportation can be reduced. By setting the lifting mechanism 123, when the workpiece 22 needs to be coated, the workpiece 22 is pushed out of the support cup 21 and transferred to the coating mechanism 121, so that the coating mechanism 121 drives the workpiece 22 to rotate, thereby coating the outer surface of the workpiece 22 with an insulating film.

[0143] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, a plurality of first bayonet holes 12211 are disposed on the outer peripheral surface of the support platform 1221 , and the plurality of first bayonet holes 12211 are disposed around the third axis, and the first bayonet holes 12211 are used to accommodate the support cup 21 .

[0144] The first clamping opening 12211 is a notch provided on the outer circumferential surface of the support platform 1221. A plurality of first clamping openings 12211 are distributed at intervals along the circumference of the support platform 1221. The support cup 21 can be clamped in the first clamping opening 12211, so as to rotate with the rotation of the support platform 1221.

[0145] By setting a plurality of first bayonet holes 12211 on the outer peripheral surface of the support platform 1221, each first bayonet hole 12211 can accommodate the support cup 21. As the second turret 122 rotates, the first bayonet holes 12211 pass through the working position in sequence, thereby transferring the support cup 21 to the working position. Afterwards, the lifting mechanism 123 and the coating mechanism 121 can drive the workpiece 22 to rotate so as to coat the insulating film on the workpiece 22.

[0146] Please refer to Figure 1 , Figure 4 and Figure 5In some embodiments, the coating device 12 includes a first retaining member 12212, which is disposed around the outer side of the support platform 1221, and is used to retain the support cup 21 in the first bayonet 12211. The retaining member includes a first feed end and a first discharge end, and the support platform 1221 is configured to transport the support cup 21 from the first feed end to the first discharge end.

[0147] The first retaining member 12212 may be an arc-shaped strip structure arranged around the outer circumference of the support platform 1221. Since the first retaining member 12212 is arranged around the outer side of the support platform 1221, the cup 21 located at the first bayonet 12211 cannot be separated from the first bayonet 12211 from the opening end of the first bayonet 12211, thereby the cup 21 is held in the first bayonet 12211.

[0148] The two opposite ends of the first retaining member 12212 are respectively the first feed end and the first discharge end. Before the first bayonet 12211 passes through the first feed end, the support cup 21 is first clamped into the first bayonet 12211. As the support platform 1221 rotates, the first bayonet 12211 passes through the first feed end and rotates to the first discharge end, and finally passes through the first discharge end, thereby allowing the support cup 21 to disengage from the first bayonet 12211 for easy discharge.

[0149] By providing the first retaining member 12212, the cup 21 is retained in the first bayonet 12211 during the rotation of the support member. The cup 21 enters the first bayonet 12211 from the first feeding end, passes through the working position as the support seat rotates, and is discharged from the first discharging end. During the whole process, the cup 21 is not easy to be separated from the first bayonet 12211, thereby improving the stability of the film coating device 12.

[0150] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the coating mechanism 121 includes a clamping member 1211 and a second driving mechanism 1212. The clamping member 1211 is arranged opposite to the lifting mechanism 123. The clamping member 1211 is used to cooperate with the lifting mechanism 123 to clamp the workpiece 22. The second driving mechanism 1212 connects the second turret 122 and the clamping member 1211. The second driving mechanism 1212 is used to drive the clamping member 1211 to rotate, so as to realize the rotation of the workpiece 22 around its own axis.

[0151] The clamping member 1211 is used to clamp one end of the workpiece 22. The clamping member 1211 can be a clamping claw structure or a flat plate structure. In this case, the surface of the clamping member 1211 can have a large friction force, so as to cooperate with the lifting mechanism 123 to clamp the workpiece 22.

[0152] The second driving mechanism 1212 is connected to the second turret 122 and the clamping member 1211 . The second driving mechanism 1212 is used to drive the clamping member 1211 to rotate, thereby driving the workpiece 22 to rotate around its own axis.

[0153] The second driving mechanism 1212 may include a rotating driving member, which is connected to the clamping member 1211, and the rotating driving member outputs a rotational motion, thereby driving the clamping member 1211 to rotate, so as to drive the workpiece 22 to rotate around its own axis. The rotating driving member may be a motor, an internal combustion engine, a rotating handle, etc. The second driving mechanism 1212 may also include a linear driving member and a transmission mechanism, and the linear driving member is connected to the clamping member 1211 through the transmission mechanism. The linear driving member outputs a linear motion, and the transmission mechanism converts the linear motion into the swing of the clamping member 1211, so as to drive the workpiece 22 to rotate around its own axis. The linear driving member may be a linear electric cylinder, a linear oil cylinder, a linear air cylinder, etc. The transmission mechanism may be a screw nut mechanism, a crank slider mechanism, etc.

[0154] Optionally, the second driving mechanism 1212 may include a rotating driving member and a transmission gear. The rotating driving member outputs a rotational motion, which drives the clamping member 1211 to rotate after being transmitted by the transmission gear.

[0155] Optionally, in order to reduce the friction force of the lifting mechanism 123 on the workpiece 22 , the end of the lifting mechanism 123 in contact with the workpiece 22 may be set to a spherical surface.

[0156] The lifting mechanism 123 lifts the workpiece 22, so that after the workpiece 22 is separated from the support cup 21, one end of the workpiece 22 can contact the clamping member 1211, so that the lifting mechanism 123 and the clamping member 1211 cooperate to clamp the workpiece 22. The second driving mechanism 1212 can drive the clamping member 1211 to rotate, thereby driving the workpiece 22 to rotate around its own axis, so that the insulating film is coated on the outer surface of the workpiece 22.

[0157] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the clamping member 1211 includes a mounting portion 12113, a clamping portion 12111 and an elastic portion 12112. The mounting portion 12113 is connected to the second driving mechanism 1212, the clamping portion 12111 is used to cooperate with the lifting mechanism 123 to clamp the workpiece 22, and the elastic portion 12112 is disposed between the mounting portion 12113 and the clamping portion 12111.

[0158] The mounting portion 12113 is a portion of the clamping member 1211 connected to the second driving mechanism 1212. The clamping portion 12111 is a portion of the clamping member 1211 used to contact the workpiece 22. Optionally, the clamping portion 12111 is in a cover shape, and the clamping portion 12111 can be designed to conform to one end of the workpiece 22, so as to just cover one end of the workpiece 22 and enhance the clamping force on the workpiece 22.

[0159] The elastic part 12112 is disposed between the mounting part 12113 and the clamping part 12111, and the elastic part 12112 can be elastically deformed. When the lifting mechanism 123 lifts the workpiece 22, the elastic part 12112 is gradually compressed, thereby forming a flexible connection between the clamping part 12111 and the mounting part 12113, reducing the risk of damage to the workpiece 22 caused by rigid contact between the workpiece 22 and the clamping part 12111. The elastic part 12112 can be a spring, rubber, etc.

[0160] When the lifting mechanism 123 lifts the workpiece 22 away from the support cup 21, the workpiece 22 contacts the clamping portion 12111 and compresses the elastic portion 12112, so that the workpiece 22 can be clamped between the clamping portion 12111 and the lifting mechanism 123. The provision of the elastic portion 12112 makes the clamping member 1211 have a certain flexibility, and the workpiece 22 is not easily damaged during the clamping process.

[0161] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the coating device 12 includes a holding mechanism 124, which is disposed on the support platform 1221. The holding mechanism 124 is used to hold the workpiece 22 between the lifting mechanism 123 and the coating mechanism 121.

[0162] The holding mechanism 124 is a mechanism for limiting the workpiece 22 between the lifting mechanism 123 and the coating mechanism 121. The holding mechanism 124 is connected to the support platform 1221, and the holding mechanism 124 can contact with the workpiece 22, so as to limit the workpiece 22.

[0163] By setting up a holding mechanism 124 to hold the workpiece 22 between the lifting mechanism 123 and the coating mechanism 121, during the rotation of the workpiece 22, the workpiece 22 is not easy to separate from between the lifting mechanism 123 and the coating mechanism 121, which is beneficial to improving the coating stability of the coating equipment 10 and ensuring the coating efficiency to a certain extent.

[0164] Please refer to Figure 1 , Figure 4 and Figure 5In some embodiments, the holding mechanism 124 includes a mounting seat 1241 and a limiting roller 1242. The mounting seat 1241 is disposed on the support platform 1221, and the limiting roller 1242 is rotatably disposed on the mounting seat 1241. The limiting roller 1242 is used to contact the workpiece 22, and the limiting roller 1242 is configured to rotate around its own axis when the coating mechanism 121 drives the workpiece 22 to rotate.

[0165] The mounting seat 1241 is the mounting base of the limiting roller 1242, and the mounting seat 1241 is connected to the support platform 1221. The limiting roller 1242 is a roller structure. The circumference of the limiting roller 1242 can contact the outer surface of the workpiece 22, thereby limiting the position of the workpiece 22.

[0166] Optionally, the rotation axis of the limiting roller 1242 is parallel to the third axis.

[0167] When the coating mechanism 121 drives the workpiece 22 to rotate around its own axis, since the workpiece 22 is in contact with the limiting roller 1242, the workpiece 22 can drive the limiting roller 1242 to rotate, and the limiting roller 1242 can limit the workpiece 22 from detaching from between the lifting mechanism 123 and the coating mechanism 121 to a certain extent.

[0168] When the coating mechanism 121 drives the workpiece 22 to rotate around its own axis, the limiting roller 1242 can contact the outer peripheral surface of the workpiece 22, thereby rotating along with the rotation of the workpiece 22, thereby achieving the effect of limiting the separation of the workpiece 22.

[0169] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the holding mechanism 124 includes a plurality of limiting rollers 1242 for being disposed around the workpiece 22 .

[0170] The holding mechanism 124 includes a plurality of limiting rollers 1242, which are arranged around the circumference of the workpiece 22. Since the workpiece 22 is accommodated in the support cup 21, and the support cup 21 is clamped in the first clamping opening 12211, the plurality of limiting rollers 1242 can also be arranged around the circumference of the first clamping opening 12211.

[0171] By providing a plurality of limiting rollers 1242, the limiting effect is better, which is beneficial to improving the stability of the film coating of the film coating device 10 and ensuring the efficiency of the film coating to a certain extent.

[0172] Please refer to Figure 1 , Figure 4 and Figure 5In some embodiments, the coating device 12 includes a smoothing mechanism 125 , and the smoothing mechanism 125 includes a smoothing member 1251 , and the smoothing member 1251 is configured to abut against the insulating film coated on the workpiece 22 when the workpiece 22 rotates following the second turret 122 .

[0173] The smoothing member 1251 is a component used to contact the insulating film wrapped around the workpiece 22. After the insulating film is bonded to the workpiece 22, in order to make the subsequent insulating film bonded to the workpiece 22 better and reduce the risk of subsequent insulating film wrinkling, the smoothing member 1251 is in contact with the insulating film wrapped around the workpiece 22. In this way, as the workpiece 22 rotates, the insulating film is smoothed by the smoothing member 1251 and then wound onto the workpiece 22, so that the quality of the film is better.

[0174] By providing the smoothing member 1251, the insulating film coated on the workpiece 22 is smoothed, the risk of the insulating film wrinkling is reduced, and the quality of the coating is improved.

[0175] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the smoothing mechanism 125 further includes a third driving mechanism 1252 , which is connected to the smoothing member 1251 , and is configured to adjust the distance between the smoothing member 1251 and the second turret 122 in the radial direction of the second turret 122 .

[0176] The third driving mechanism 1252 may include a linear driving member, which is connected to the smoothing member 1251. The linear driving member outputs linear motion, thereby driving the smoothing member 1251 to approach or move away from the second turret 122, so as to adjust the radial distance between the smoothing member 1251 and the second turret 122. The linear driving member may be a linear electric cylinder, a linear oil cylinder, a linear air cylinder, etc. The third driving mechanism 1252 may also include a rotating driving member and a transmission mechanism, and the rotating driving member is connected to the smoothing member 1251 through the transmission mechanism. The rotating driving member outputs rotational motion, and the transmission mechanism converts the rotational motion into linear motion of the smoothing member 1251, so as to adjust the radial distance between the smoothing member 1251 and the second turret 122. The rotating driving member may be a motor, an internal combustion engine, a rotating handle, etc. The transmission mechanism may be a screw nut mechanism, a crank slider mechanism, etc.

[0177] As the number of layers of the insulating film coated on the workpiece 22 increases, the force between the workpiece 22 and the smoothing member 1251 increases. By setting the third driving mechanism 1252 to adjust the radial position of the smoothing member 1251 on the second turret 122, the smoothing member 1251 can always be in contact with the insulating film on the workpiece 22 before the insulating film coating is completed, which neither applies a large external force to the workpiece 22 to allow the workpiece 22 to separate from the coating mechanism 121 and the lifting mechanism 123, but can also smooth the insulating film.

[0178] Please refer to Figure 1 and Figure 5 , Figure 5 A schematic diagram of the structure of a film coating device 12 provided in some embodiments of the present application. In some embodiments, the film coating device 10 includes a plurality of unwinding mechanisms 13, and the unwinding mechanisms 13 are used to unwind the insulating tape 23. The plurality of unwinding mechanisms 13 selectively provide the insulating tape 23 to the picking mechanism 111.

[0179] The unwinding mechanism 13 is a mechanism for unwinding the insulating tape 23. The insulating tape 23 unwinding by the unwinding mechanism 13 can be picked up by the picking-up mechanism 111 located at the film preparation position.

[0180] The film coating device 10 includes a plurality of unwinding mechanisms 13. When working, only one unwinding mechanism 13 among the plurality of unwinding mechanisms 13 provides the insulating tape 23 to the picking mechanism 111. The other unwinding mechanisms 13 are in a waiting state. When the insulating tape 23 of the working unwinding mechanism 13 is unwound, the other unwinding mechanisms 13 can be switched to continue to provide the insulating tape 23 to the picking mechanism 111.

[0181] The unwinding mechanism 13 can unwind the insulating tape 23, thereby providing the insulating tape 23 to the picking mechanism 111. By providing a plurality of unwinding mechanisms 13, the plurality of unwinding mechanisms 13 selectively provide the insulating tape 23 to the picking mechanism 111, so that when the insulating tape 23 of one unwinding mechanism 13 is exhausted, other unwinding mechanisms 13 can be switched to continue to provide the insulating tape 23 to the picking mechanism 111, thereby reducing downtime and improving film coating efficiency.

[0182] Please refer to Figure 1 and Figure 5In some embodiments, the unwinding mechanism 13 includes an unwinding roller 131, a fixed frame 132, a movable frame 133, and a fourth driving mechanism 135. The unwinding roller 131 is used to unwind the insulating tape 23, and the unwinding roller 131 is disposed on the fixed frame 132. The movable frame 133 is provided with a guide 134, and the guide 134 is used to guide the insulating tape 23 to the picking mechanism 111, and the movable frame 133 is slidably connected to the fixed frame 132. The fourth driving mechanism 135 is connected to the fixed frame 132 and the movable frame 133, and the fourth driving mechanism 135 is used to drive the movable frame 133 to slide relative to the fixed frame 132, so that the guide 134 is close to or away from the picking mechanism 111.

[0183] The unwinding roller 131 is a roller for unwinding the insulating tape 23. The insulating tape roll is mounted on the unwinding roller 131, and the insulating tape 23 is unwound as the unwinding roller 131 rotates.

[0184] The fixed frame 132 is an inactive mounting frame relative to the ground or the machine. The unwinding roller 131 is mounted on the fixed frame 132 so that the unwinding roller 131 can stably unwind the insulating tape 23 .

[0185] The movable frame 133 is a frame structure that can move relative to the fixed frame 132. The movable frame 133 is slidably connected to the fixed frame 132, the fourth driving mechanism 135 can be installed on the fixed frame 132, and the output end of the fourth driving mechanism 135 can be connected to the movable frame 133. When the fourth driving mechanism 135 is activated, it can drive the movable frame 133 to slide relative to the fixed frame 132.

[0186] The fourth driving mechanism 135 may include a linear driving member, which is mounted on the fixed frame 132. The output end of the linear driving member is connected to the movable frame 133. The linear driving member outputs a linear motion, thereby driving the movable frame 133 to slide relative to the fixed frame 132, so that the guide member 134 is close to or away from the picking mechanism 111. The linear driving member may be a linear electric cylinder, a linear oil cylinder, a linear air cylinder, etc. The fourth driving mechanism 135 may also include a rotating driving member and a transmission mechanism. The rotating driving member is mounted on the fixed frame 132, and the rotating driving member is connected to the movable frame 133 through the transmission mechanism. The rotating driving member outputs a rotational motion, and the transmission mechanism converts the rotational motion into the movement of the movable frame 133, so that the guide member 134 is close to or away from the picking mechanism 111. The rotating driving member may be a motor, an internal combustion engine, a rotating handle, etc. The transmission mechanism may be a screw nut mechanism, a crank slider mechanism, etc.

[0187] The guide member 134 is disposed on the movable frame 133, and is used to guide the insulating tape 23 to the picking mechanism 111. Optionally, the guide member 134 is a guide plate extending toward the picking mechanism 111, and the insulating tape 23 is guided to the picking mechanism 111 through the guide plate.

[0188] By slidably connecting the movable frame 133 and the fixed frame 132, the fourth driving mechanism 135 can drive the movable frame 133 to approach the picking mechanism 111 relative to the fixed frame 132, so that the insulating tape 23 unwound by the unwinding roller 131 can approach the picking mechanism 111 after passing through the guide 134, thereby providing the insulating tape 23 to the picking mechanism 111. The fourth driving mechanism 135 can also drive the movable frame 133 to move away from the picking mechanism 111 relative to the fixed frame 132, thereby stopping providing the insulating tape 23 to the picking mechanism 111.

[0189] Optionally, one side of the insulating tape 23 is sticky or provided with an adhesive layer. In order to protect the stickiness or adhesive layer of the insulating tape 23 to a certain extent, a protective film 24 is also provided on the sticky side or adhesive layer of the insulating tape 23. The unwinding mechanism 13 also includes a winding roller 1331, and the winding roller 1331 is used to wind up the protective film 24. The protective film 24 and the insulating tape 23 are separated on the guide 134, wherein the protective film 24 is wound up by the winding roller 1331, and the insulating tape 23 is fed to the picking mechanism 111. By providing the winding roller 1331, the protective film 24 can be automatically peeled off the insulating tape 23, which is conducive to improving the degree of automation.

[0190] In addition, the unwinding mechanism 13 may further include a deviation correction component to detect and correct the deviation of the insulating tape 23 .

[0191] Please refer to Figure 1 and Figure 5 In some embodiments, the unwinding mechanism 13 further includes a laminating mechanism 136 , and the laminating mechanism 136 is used to press the insulating tape 23 led out by the guide member 134 onto the picking mechanism 111 .

[0192] The film pressing mechanism 136 may include a film pressing driving member and a film pressing member, wherein the film pressing driving member is connected to the film pressing member, and the film pressing driving member is used to drive the film pressing member to approach the picking mechanism 111, thereby pressing the insulating material tape 23 to the picking mechanism 111, and the film pressing driving member is also used to drive the film pressing member away from the picking mechanism 111, thereby releasing the insulating material tape 23. The film pressing driving member may be a linear cylinder, a linear electric cylinder, a linear oil cylinder, etc.

[0193] Optionally, the film pressing member is a roller. Using the roller as the film pressing member can reduce the impact on the insulating tape 23 and reduce the risk of damage to the insulating tape 23.

[0194] The film pressing mechanism 136 can be arranged in a one-to-one correspondence with the unwinding mechanism 13 .

[0195] By providing a film pressing mechanism 136 to press the insulating tape 23 led out by the guide 134 onto the picking mechanism 111, the unwinding mechanism 13 can provide the insulating tape 23 to the picking mechanism 111 more stably, reducing the risk of downtime due to supply interruption, and ensuring the efficiency of film coating to a certain extent.

[0196] Please refer to Figure 1 and Figure 5 In some embodiments, the unwinding mechanism 13 includes a first roller 137 and a second roller 138, wherein the first roller 137 is disposed on the fixed frame 132, and the second roller 138 is disposed on the movable frame 133. The insulating tape 23 is wound around the first roller 137 and the second roller 138. The unwinding mechanism 13 also includes a clamping mechanism 139, which is disposed upstream of the first roller 137 and is used to clamp or loosen the insulating tape 23.

[0197] The first roller 137 is a roller structure disposed on the fixed frame 132. The second roller 138 is a roller structure disposed on the movable frame 133. When the film coating device 10 is used for the first time, the insulating tape 23 needs to be passed through or wound around the first roller 137, the clamping mechanism 139, the second roller 138 and the guide 134 in sequence.

[0198] The clamping mechanism 139 is a mechanism for clamping or loosening the insulating tape 23. The clamping mechanism 139 may include a first clamping arm and a second clamping arm, and when the first clamping arm is pressed against the second clamping arm, the clamping mechanism 139 clamps the insulating tape 23. When the first clamping arm is away from the second clamping arm, the clamping mechanism 139 loosens the insulating tape 23.

[0199] Before the film coating device 10 works, the insulating tape 23 needs to be set on the unwinding roller 131, and pass through the first over-roller 137, the second over-roller 138 and the guide 134 in sequence, so as to prepare to feed the picking mechanism 111. When the insulating tape 23 on the unwinding roller 131 is exhausted, the other unwinding mechanism 13 is switched to feed the picking mechanism 111, and then the insulating tape 23 upstream of the clamping mechanism 139 is manually cut off, and the new insulating tape 23 is replaced with the old insulating tape 23 clamped by the clamping mechanism 139. The installation of the new insulating tape 23 can be completed without passing through the first over-roller 137, the second over-roller 138 and the guide 134 in sequence, which increases the convenience of replacing the insulating tape 23.

[0200] Please refer to Figure 7 , Figure 7 A simplified schematic diagram of the cooperation between an unwinding mechanism 13 and a film preparation device 11 provided in some embodiments of the present application. Figure 7 In the illustrated embodiment, an unwinding mechanism 13 located on the left side supplies the insulating material tape 23 to the pickup mechanism 111 of the film preparation device 11 .

[0201] Please refer to Figure 8 , Figure 8 A simplified schematic diagram of the unwinding mechanism 13 and the film preparation device 11 provided in some embodiments of the present application are separated. When the insulating tape 23 of the unwinding mechanism 13 on the left side is unwound, the film pressing mechanism 136 corresponding to the unwinding mechanism 13 on the left side first releases the insulating tape 23, and the fourth driving mechanism 135 of the unwinding mechanism 13 on the left side drives the movable frame 133 to move away from the picking mechanism 111 relative to the fixed frame 132.

[0202] Please refer to Fig. 9 , Fig. 9 Another simplified schematic diagram of the cooperation between the unwinding mechanism 13 and the film preparation device 11 provided for some embodiments of the present application. The fourth driving mechanism 135 of the unwinding mechanism 13 on the right side drives the movable frame 133 to approach the picking mechanism 111 relative to the fixed frame 132, and the film pressing mechanism 136 corresponding to the unwinding mechanism 13 on the right side presses the insulating tape 23 unwound by the unwinding mechanism 13 on the right side onto the picking mechanism 111. In this way, the two unwinding mechanisms 13 are switched. During the unwinding process of the unwinding mechanism 13 on the right side, the insulating tape roll can be reinstalled for the unwinding mechanism 13 on the left side.

[0203] Please refer to Figure 1 and Fig.10 , Fig.10 Schematic diagram of the cooperation between the film preparation device 11 and the waste collection device 142 provided in some embodiments of the present application. In some embodiments, the film coating device 10 further includes a detection mechanism 141 and a waste collection device 142, and the detection mechanism 141 is used to detect the insulating film. The waste collection device 142 is electrically connected to the detection mechanism 141, and the waste collection device 142 responds to the detection mechanism 141 to peel the insulating film off the picking mechanism 111.

[0204] The detection mechanism 141 is used to detect the insulating film to confirm whether the insulating film meets the requirements. For example, the detection mechanism 141 can detect the appearance of the insulating film to confirm whether it is wrinkled. The detection mechanism 141 can be an industrial camera to confirm whether the insulating film meets the requirements by taking pictures and comparing them.

[0205] It should be noted that the detection mechanism 141 can also identify the joint between the new insulating tape 23 and the old insulating tape 23 , and the waste collection mechanism can respond to the detection mechanism 141 , thereby stripping the insulating film having this joint from the picking mechanism 111 .

[0206] The waste collecting device 142 is a device for peeling off the defective insulating film from the picking mechanism 111. Optionally, the waste collecting device 142 includes a robot, and the defective insulating film is peeled off from the picking mechanism 111 by the robot.

[0207] The waste collecting device 142 may be directly electrically connected to the detection mechanism 141, or may be electrically connected to the detection mechanism 141 through an intermediate component. For example, the waste collecting device 142 is electrically connected to the detection mechanism 141 through a controller. When the detection mechanism 141 detects a defective insulating film, the controller controls the waste collecting device 142 to peel off the defective insulating film from the device of the picking mechanism 111.

[0208] The detection mechanism 141 can detect the insulating film. When the detection mechanism 141 detects that the insulating film is wrinkled or has other problems, the waste collection device 142 will peel off the problematic insulating film from the picking mechanism 111, thereby reducing the risk of coating the problematic insulating film on the workpiece 22 and ensuring the coating quality to a certain extent.

[0209] Please refer to Figure 1 and Fig.10 In some embodiments, the waste collecting device 142 includes a winding member 1421, and the winding member 1421 is used to contact the insulating film and wind the insulating film.

[0210] The winding member 1421 can be set as a cylindrical structure to improve the effect of winding the insulating film. Optionally, the winding member 1421 is sleeved on the inflatable shaft so that the entire mechanism has flexible protection and reduces the risk of damage to the mechanism due to overpressure.

[0211] When the detection mechanism 141 detects that the insulating film is wrinkled or has other problems, the winding member 1421 of the waste collection device 142 can contact the insulating film, and the insulating film can be adhered to the winding member 1421, thereby rolling up the insulating film to peel the insulating film off the picking mechanism 111, which is simple and convenient.

[0212] Please refer to Figure 1 and Fig.10 In some embodiments, the waste collecting device 142 further includes a fifth driving mechanism 1422, and the fifth driving mechanism 1422 is connected to the winding member 1421. The fifth driving mechanism 1422 is used to drive the winding member 1421 to rotate so that the insulating film is wound around the winding member 1421.

[0213] The fifth driving mechanism 1422 is a driving mechanism for driving the winding member 1421 to rotate. The fifth driving mechanism 1422 may include a rotating driving member, which is connected to the winding member 1421, so as to drive the winding member 1421 to rotate. The rotating driving member may be a motor, an internal combustion engine, etc. The fifth driving mechanism 1422 may also include a linear driving member and a transmission mechanism, and the linear driving member is connected to the winding member 1421 through the transmission mechanism. The linear driving member outputs linear motion, and the transmission mechanism converts the linear motion into the rotation of the winding member 1421, so that the insulating film is wound on the winding member 1421. The linear driving member may be a linear electric cylinder, a linear oil cylinder, a linear air cylinder, etc. The transmission mechanism may be a screw nut mechanism, a crank slider mechanism, etc.

[0214] By providing the fifth driving mechanism 1422 , the winding member 1421 can be driven to actively rotate, so that the insulating film can be rolled up onto the winding member 1421 more conveniently.

[0215] Please refer to Figure 1 and Fig.10 In some embodiments, the waste collecting device 142 further includes a sixth driving mechanism 1423 , which is connected to the winding member 1421 , and is used to drive the winding member 1421 to move closer to or away from the picking mechanism 111 .

[0216] The sixth driving mechanism 1423 is connected to the winding member 1421, and is used to drive the winding member 1421 to approach or move away from the picking mechanism 111. The sixth driving mechanism 1423 can drive the winding member 1421 to move, so that the winding member 1421 approaches or moves away from the picking mechanism 111. The sixth driving mechanism 1423 can also drive the winding member 1421 to swing or rotate, so that the winding member 1421 approaches or moves away from the picking mechanism 111.

[0217] The sixth driving mechanism 1423 may include a linear driving member, which is connected to the winding member 1421, and the linear driving member outputs a linear motion, thereby driving the winding member 1421 to move, so that the winding member 1421 is close to or away from the picking mechanism 111. The linear driving member may be a linear electric cylinder, a linear oil cylinder, a linear air cylinder, etc. The sixth driving mechanism 1423 may also include a rotating driving member and a transmission mechanism, and the rotating driving member is connected to the winding member 1421 through the transmission mechanism. The rotating driving member outputs a rotational motion, and the transmission mechanism converts the rotational motion into the movement of the winding member 1421, so that the winding member 1421 is close to or away from the picking mechanism 111. The rotating driving member may be a motor, an internal combustion engine, a rotating handle, etc. The transmission mechanism may be a screw nut mechanism, a crank slider mechanism, etc.

[0218] As the winding member 1421 continuously reels the problematic insulating film, the insulating film on the winding member 1421 gradually increases, and the overall diameter of the winding member 1421 increases. In order to reduce the stress of the winding member 1421 on the picking mechanism 111, the sixth driving mechanism 1423 can adjust the distance between the winding member 1421 and the picking mechanism 111, so that the winding member 1421 can be close to the picking mechanism 111 to reel in the problematic insulating film, and control the distance from the picking mechanism 111 during reeling, thereby reducing the stress on the picking mechanism 111. In addition, when there is no need to reel in the insulating film, the sixth driving mechanism 1423 can drive the winding member 1421 away from the picking mechanism 111, thereby reducing the risk of interference with the picking mechanism 111.

[0219] Please refer to Figure 1 and Fig.11 , Fig.11 The following is a schematic diagram of the cooperation between the film coating device 12 and the feeding mechanism 15 provided in some embodiments of the present application. In some embodiments, the film coating device 12 includes the feeding mechanism 15, and the feeding mechanism 15 is used to transport the workpiece 22 to the film coating device 12.

[0220] The feeding mechanism 15 is a mechanism for feeding the workpiece 22 to the coating device 12. The feeding mechanism 15 may include a conveyor belt, a pull belt, and the like.

[0221] By providing the feeding mechanism 15 , it is convenient to convey the workpiece 22 to the coating device 12 , which is beneficial to improving the automation level of the coating equipment 10 .

[0222] Please refer to Figure 1 and Fig.11 In some embodiments, the loading mechanism 15 includes a turntable 151 for placing a support cup 21 and a second holder 152, and the support cup 21 is used to accommodate the workpiece 22. A second bayonet 1511 is provided on the outer periphery of the turntable 151. The second holder 152 is arranged around the outer side of the turntable 151, and the second holder 152 is used to hold the support cup 21 in the second bayonet 1511. The holder includes a second feed end and a second discharge end, and the turntable 151 is configured to transport the support cup 21 from the second feed end to the second discharge end, and the coating device 12 receives the support cup 21 at the second discharge end.

[0223] The second clamping opening 1511 is a notch provided on the outside of the rotating disk 151. The support cup 21 can be clamped in the second clamping opening 1511, so as to rotate along with the rotation of the rotating disk 151.

[0224] The second retaining member 152 may be an arc-shaped strip structure disposed around the outer circumference of the rotating disk 151. Since the second retaining member 152 is disposed around the outer side of the rotating disk 151, the cup 21 located at the second bayonet 1511 cannot be separated from the second bayonet 1511 from the opening end of the second bayonet 1511, thereby retaining the cup 21 in the second bayonet 1511.

[0225] The opposite ends of the second retaining member 152 are respectively the second feed end and the second discharge end. Before the second bayonet 1511 passes through the second feed end, the support cup 21 is first clamped into the second bayonet 1511. As the turntable 151 rotates, the second bayonet 1511 passes through the second feed end to rotate toward the second discharge end, and finally passes through the second discharge end, thereby allowing the support cup 21 to disengage from the second bayonet 1511, so as to facilitate the loading of the support cup 21 onto the coating device 12.

[0226] By arranging a plurality of second bayonet openings 1511 on the outer circumference of the turntable 151, each second bayonet opening 1511 can accommodate the cup 21, and during the rotation of the turntable 151, the second retainer 152 retains the cup 21 in the second bayonet opening 1511. The cup 21 enters the second bayonet opening 1511 from the second feeding end, and as the turntable 151 rotates, the workpiece 22 is discharged from the second discharging end to the film coating device 12. During this whole process, the cup 21 is not easy to be separated from the second bayonet opening 1511, thereby improving the stability of the film coating device 12. In addition, during the conveying process, the cup 21 is always in contact with the turntable 151, and the workpiece 22 is protected by the cup 21, thereby reducing the risk of damage to the workpiece 22 during the conveying process.

[0227] Please refer to Figure 1 and Fig.11 In some embodiments, a plurality of second bayonet holes 1511 are disposed on the turntable 151 , and the plurality of second bayonet holes 1511 are spaced apart along the circumference of the turntable 151 .

[0228] By providing a plurality of second bayonet ports 1511 , a plurality of cups 21 can be transported when the turntable 151 rotates, thereby improving the transport efficiency.

[0229] Please refer again Figure 1 In some embodiments, the coating device 10 includes a material unloading mechanism 16 , and the material unloading mechanism 16 is used to realize the unloading of the workpiece 22 located at the coating device 12 .

[0230] The unloading mechanism 16 is a mechanism for unloading the workpiece 22 in the coating device 12. The unloading mechanism 16 may include a conveyor belt, a pull belt, etc. The structure of the unloading mechanism 16 may also be the same as that of the loading mechanism 15, and will not be repeated here.

[0231] By providing the unloading mechanism 16 , it is convenient to unload the workpiece 22 from the coating device 12 , which is beneficial to improving the automation level of the coating equipment 10 .

[0232] Please refer to Figure 1 In some embodiments, the film coating device 10 further includes a first conveying mechanism 153, a second conveying mechanism 18, a third conveying mechanism and a verification mechanism 17. The second conveying mechanism 18 is used to convey the workpiece 22 to the verification mechanism 17, and the verification mechanism 17 is used to verify the workpiece 22 (verify various indicators of the workpiece 22, which can be confirmed by scanning the QR code on the workpiece 22). When the workpiece 22 passes the verification of the verification mechanism 17, the first conveying mechanism 153 conveys the workpiece 22 to the feeding mechanism 15. When the workpiece 22 fails to pass the verification, the third conveying mechanism conveys the workpiece 22 to the waste box.

[0233] The first conveying mechanism 153, the second conveying mechanism 18 and the third conveying mechanism may include a conveyor belt, a pull belt, etc., and may also have the same structure as the feeding mechanism 15, which will not be repeated here.

[0234] In the present application, the driving gear disposed on the second turret 122 can be meshed with the driven gears on the first turret 1121 and the rotating disk 151, thereby driving the first turret 1121 and the rotating disk 151 to rotate. The first turret 1121 and the plurality of rotating disks 151 are driven to rotate by an active power.

[0235] It should be noted that in the coating device 10 provided in the embodiment of the present application, an insulating tape 23 with stickiness or an adhesive layer can be used. When the insulating film cut from the insulating tape 23 is coated on the workpiece 22, the connection strength with the workpiece 22 is higher and the connection stability is better.

[0236] The working process of the coating device 10 provided in the embodiment of the present application is as follows:

[0237] First, the second conveying mechanism 18 conveys the workpiece 22 to the checking mechanism 17, and the checking mechanism 17 checks the workpiece 22. When the workpiece 22 passes the check of the checking mechanism 17, the first conveying mechanism 153 conveys the workpiece 22 to the feeding mechanism 15. When the workpiece 22 fails to pass the check, the third conveying mechanism conveys the workpiece 22 to the waste box.

[0238] The loading mechanism 15 transfers the workpiece 22 to the coating device 12 , and the workpiece 22 is sequentially inserted into the first clamping opening 12211 of the support table 1221 , and is guided to the working position as the first turret 1121 rotates.

[0239] When the workpiece 22 is conveyed to the film coating device 12, the unwinding mechanism 13 unwinds the insulating tape 23, the picking mechanism 111 receives the insulating tape 23, and conveys the insulating tape 23 from the film preparation position to the film coating position. In the process of conveying from the film preparation position to the film coating position, the insulating tape 23 gradually and completely covers the adsorbent 1111, and the film pressing mechanism 136 presses the insulating tape 23 onto the adsorbent 1111. Then, the cutting mechanism 19 cuts the insulating tape 23 to form an insulating film.

[0240] When the picking mechanism 111 reaches the coating position, the coating mechanism 121 also reaches the working position. At this time, the lifting mechanism 123 pushes the workpiece 22 out of the cup 21 and cooperates with the coating mechanism 121 to clamp the workpiece 22. The insulating film contacts the workpiece 22. As the workpiece 22 rotates around its own axis and the smoothing member 1251 presses the insulating film onto the workpiece 22, the insulating film gradually wraps around the workpiece 22, thereby completing the coating. Afterwards, as the second turret 122 continues to rotate, the coated workpiece 22 is unloaded from the unloading mechanism 16.

[0241] In some embodiments, the film coating device 10 includes two unwinding mechanisms 13, and the two unwinding mechanisms 13 selectively provide the insulating tape 23 to the picking mechanism 111. When the insulating tape 23 of the first unwinding mechanism 13 is unwound, the film pressing mechanism 136 corresponding to the first unwinding mechanism 13 first releases the insulating tape 23, and the fourth driving mechanism 135 of the first unwinding mechanism 13 drives the movable frame 133 to move away from the picking mechanism 111 relative to the fixed frame 132. The fourth driving mechanism 135 of the second unwinding mechanism 13 drives the movable frame 133 to move closer to the picking mechanism 111 relative to the fixed frame 132, and the film pressing mechanism 136 corresponding to the second unwinding mechanism 13 presses the insulating tape 23 unwound by the second unwinding mechanism 13 onto the picking mechanism 111. In this way, the two unwinding mechanisms 13 are switched. During the unwinding process of the second unwinding mechanism 13, the insulating tape roll can be reinstalled for the first unwinding mechanism 13.

[0242] During the operation of the coating device 10, the detection mechanism 141 can detect the insulating film in real time. When the detection mechanism 141 detects that the insulating film is wrinkled or has other problems (for example, identifying the joint between the new insulating tape 23 and the old insulating tape 23), the waste collection device 142 peels off the problematic insulating film from the picking mechanism 111, thereby reducing the risk of coating the problematic insulating film onto the workpiece 22 and ensuring the coating quality to a certain extent.

[0243] According to some embodiments of this application, please refer to Figures 1 to 11 .

[0244] The embodiment of the present application provides a coating device 10, which includes a coating device 11, a cutting mechanism 19 and a coating device 12. The coating device 11 includes a switching mechanism 112 and a plurality of picking mechanisms 111, and the plurality of picking mechanisms 111 are connected to the switching mechanism 112. The picking mechanism 111 has a coating position and a coating position, and the switching mechanism 112 is used to realize the switching of the picking mechanism 111 between the coating position and the coating position, and the picking mechanism 111 is used to pick up the insulating tape 23 at the coating position. The cutting mechanism 19 is used to cut the insulating tape 23 to form an insulating film. The coating device 12 is used to coat the insulating film picked up by the picking mechanism 111 at the coating position on the outer surface of the workpiece 22. When the coating device 10 is working, a plurality of picking mechanisms 111 are switched between the film preparation position and the coating position in turn. When one picking mechanism 111 is located at the coating position, other picking mechanisms 111 can prepare the insulating film at the coating preparation position. In this way, while the coating device 12 is coating, the film preparation device 11 starts to prepare the film. After the coating of the previous workpiece 22 is completed, the coating of the next workpiece 22 can be started immediately, and the originally serial actions are changed into parallel actions, thereby improving the efficiency of coating.

[0245] The switching mechanism 112 includes a first turret 1121, and a plurality of picking mechanisms 111 are arranged on the first turret 1121 around a first axis. The first turret 1121 is configured to realize the switching of the picking mechanisms 111 between the film preparation position and the film coating position when rotating around the first axis. The plurality of picking mechanisms 111 are arranged on the first turret 1121, and as the first turret 1121 rotates, the plurality of picking mechanisms 111 reciprocate between the film coating position and the film preparation position in turn. By setting the first turret 1121, the position switching of the plurality of picking mechanisms 111 is realized simply and conveniently, with low cost and high stability.

[0246] The coating device 12 includes a second turret 122 and a plurality of coating mechanisms 121. The plurality of coating mechanisms 121 are arranged on the second turret 122 around a third axis. The second turret 122 is configured to switch the coating mechanism 121 to a working position when rotating around the third axis. The coating mechanism 121 is used to drive the workpiece 22 to rotate around its own axis at the working position so that the insulating film is coated on the outer surface of the workpiece 22. One coating mechanism 121 can coat one workpiece 22. The plurality of coating mechanisms 121 are arranged on the second turret 122. As the second turret 122 rotates, the plurality of coating mechanisms 121 are switched to the working position in sequence. In this way, after the coating of the previous workpiece 22 is completed, the coating of the next workpiece 22 can be started immediately, and the original serial action is changed to parallel, thereby improving the coating efficiency. One side of the insulating film is sticky. During coating, the insulating film picked up by the picking mechanism 111 located at the coating position can contact with the workpiece 22, thereby bonding to the workpiece 22. The coating mechanism 121 drives the workpiece 22 to rotate around its own axis, so that the insulating film is gradually wound and adhered to the outer surface of the workpiece 22. This coating method has a fast coating speed and high efficiency.

[0247] The second turret 122 includes a support table 1221 for placing a support cup 21, and the support cup 21 is used to accommodate a workpiece 22. A lifting mechanism 123 is provided on the support table 1221, and the lifting mechanism 123 is used to lift the workpiece 22, so as to separate the workpiece 22 from the support cup 21 and transfer it to the coating mechanism 121. By placing the workpiece 22 in the support cup 21, the workpiece 22 can be protected and the damage to the workpiece 22 during transportation can be reduced. By providing the lifting mechanism 123, when the workpiece 22 needs to be coated, the workpiece 22 is pushed out of the support cup 21 and transferred to the coating mechanism 121, so that the coating mechanism 121 can drive the workpiece 22 to rotate, so that the insulating film is coated on the outer surface of the workpiece 22.

[0248] A plurality of first bayonet holes 12211 are arranged on the outer peripheral surface of the support platform 1221, and the plurality of first bayonet holes 12211 are arranged around the third axis, and the first bayonet holes 12211 are used to accommodate the support cup 21. The coating device 12 includes a first retaining member 12212, and the first retaining member 12212 is arranged around the outer side of the support platform 1221, and the first retaining member 12212 is used to retain the support cup 21 in the first bayonet hole 12211, and the retaining member includes a first feeding end and a first discharging end, and the support platform 1221 is configured to transport the support cup 21 from the first feeding end to the first discharging end. By setting a plurality of first bayonet ports 12211 on the outer peripheral surface of the support platform 1221, each first bayonet port 12211 can accommodate the support cup 21. As the second turret 122 rotates, the first bayonet ports 12211 pass through the working position in sequence, thereby transferring the support cup 21 to the working position. Afterwards, the lifting mechanism 123 and the coating mechanism 121 can drive the workpiece 22 to rotate, so as to coat the insulating film on the workpiece 22. By setting a first retaining member 12212, the support cup 21 is retained in the first bayonet port 12211 during the rotation of the support member. The support cup 21 enters the first bayonet port 12211 from the first feeding end, passes through the working position as the support seat rotates, and is discharged from the first discharging end. During the whole process, the support cup 21 is not easy to separate from the first bayonet port 12211, thereby improving the stability of the coating device 12.

[0249] The film coating device 10 includes a plurality of unwinding mechanisms 13, the unwinding mechanisms 13 are used to unwind the insulating tape 23, and the plurality of unwinding mechanisms 13 selectively provide the insulating tape 23 to the picking mechanism 111. The unwinding mechanism 13 includes an unwinding roller 131, a fixed frame 132, a movable frame 133 and a fourth driving mechanism 135. The unwinding roller 131 is used to unwind the insulating tape 23. The unwinding roller 131 is arranged on the fixed frame 132. The movable frame 133 is provided with a guide 134, and the guide 134 is used to guide the insulating tape 23 to the picking mechanism 111, and the movable frame 133 is slidably connected to the fixed frame 132. The fourth driving mechanism 135 is connected to the fixed frame 132 and the movable frame 133, and the fourth driving mechanism 135 is used to drive the movable frame 133 to slide relative to the fixed frame 132, so that the guide 134 is close to or away from the picking mechanism 111. The unwinding mechanism 13 can unwind the insulating tape 23, thereby providing the insulating tape 23 to the picking mechanism 111. By providing a plurality of unwinding mechanisms 13, the plurality of unwinding mechanisms 13 selectively provide the insulating tape 23 to the picking mechanism 111. In this way, when the insulating tape 23 of one unwinding mechanism 13 is exhausted, other unwinding mechanisms 13 can be switched to continue to provide the insulating tape 23 to the picking mechanism 111, thereby reducing downtime and improving film coating efficiency. By slidably connecting the movable frame 133 with the fixed frame 132, the fourth driving mechanism 135 can drive the movable frame 133 to approach the picking mechanism 111 relative to the fixed frame 132, so that the insulating tape 23 unwound by the unwinding roller 131 can approach the picking mechanism 111 after passing through the guide 134, thereby providing the insulating tape 23 to the picking mechanism 111. The fourth driving mechanism 135 can also drive the movable frame 133 to move away from the picking mechanism 111 relative to the fixed frame 132 , thereby stopping providing the insulating tape 23 to the picking mechanism 111 .

[0250] The film wrapping device 10 further includes a detection mechanism 141 and a waste material collecting device 142. The detection mechanism 141 is used to detect the insulating film. The waste material collecting device 142 is electrically connected to the detection mechanism 141. The waste material collecting device 142 responds to the detection mechanism 141 to peel the insulating film off the picking mechanism 111. The waste material collecting device 142 includes a winding member 1421. The winding member 1421 is used to contact with the insulating film and wind the insulating film. The waste material collecting device 142 further includes a fifth driving mechanism 1422. The fifth driving mechanism 1422 is connected to the winding member 1421. The fifth driving mechanism 1422 is used to drive the winding member 1421 to rotate so that the insulating film is wound around the winding member 1421. The waste material collecting device 142 further includes a sixth driving mechanism 1423. The sixth driving mechanism 1423 is connected to the winding member 1421. The sixth driving mechanism 1423 is used to drive the winding member 1421 to approach or move away from the picking mechanism 111. The detection mechanism 141 can detect the insulating film. When the detection mechanism 141 detects that the insulating film is wrinkled or has other problems, the waste collecting device 142 peels off the problematic insulating film from the picking mechanism 111, thereby reducing the risk of coating the problematic insulating film on the workpiece 22, and ensuring the coating quality to a certain extent. When the detection mechanism 141 detects that the insulating film is wrinkled or has other problems, the winding member 1421 of the waste collecting device 142 can contact the insulating film, and the insulating film can be bonded to the winding member 1421, so as to roll up the insulating film, so as to peel off the insulating film from the picking mechanism 111, which is simple and convenient. By setting up the fifth driving mechanism 1422, the winding member 1421 can be driven to rotate actively, so that the insulating film can be more conveniently rolled onto the winding member 1421. As the winding member 1421 continuously reels the problematic insulating film, the insulating film on the winding member 1421 gradually increases, and the overall diameter of the winding member 1421 increases. In order to reduce the stress of the winding member 1421 on the picking mechanism 111, the sixth driving mechanism 1423 can adjust the distance between the winding member 1421 and the picking mechanism 111, so that the winding member 1421 can be close to the picking mechanism 111 to reel in the problematic insulating film, and control the distance from the picking mechanism 111 during reeling, thereby reducing the stress on the picking mechanism 111. In addition, when there is no need to reel in the insulating film, the sixth driving mechanism 1423 can drive the winding member 1421 away from the picking mechanism 111, thereby reducing the risk of interference with the picking mechanism 111.

[0251] The coating device 12 includes a loading mechanism 15, which is used to transport the workpiece 22 to the coating device 12. The loading mechanism 15 includes a turntable 151 for placing a cup 21 and a second holder 152, the cup 21 is used to accommodate the workpiece 22, the outer periphery of the turntable 151 is provided with a second bayonet 1511, the second holder 152 is arranged around the outer side of the turntable 151, the second holder 152 is used to hold the cup 21 in the second bayonet 1511, the holder includes a second feed end and a second discharge end, the turntable 151 is configured to transport the cup 21 from the second feed end to the second discharge end, and the coating device 12 receives the cup 21 at the second discharge end. By providing the loading mechanism 15, it is convenient to transport the workpiece 22 to the coating device 12, which is conducive to improving the degree of automation of the coating equipment 10. By providing the second bayonet 1511 on the outer circumference of the turntable 151, the second bayonet 1511 can accommodate the cup 21. During the rotation of the turntable 151, the second retainer 152 retains the cup 21 in the second bayonet 1511. The cup 21 enters the second bayonet 1511 from the second feeding end, and as the turntable 151 rotates, the workpiece 22 is discharged from the second discharging end to the film coating device 12. During this whole process, the cup 21 is not easy to be separated from the second bayonet 1511, thereby improving the stability of the film coating device 12. In addition, during the conveying process, the cup 21 is always in contact with the turntable 151, and the workpiece 22 is protected by the cup 21, thereby reducing the risk of damage to the workpiece 22 during the conveying process.
