[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application entitled “Encapsulation Device” filed on September 8, 2023 (application number: 2023111598272), the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to the field of batteries, and in particular to a film coating device. Background Art

[0004] Batteries are widely used in new energy applications, such as electric vehicles and new energy vehicles. These have become a new trend in the automotive industry. During battery production, the battery's outer surface must be coated with an insulating film. The efficiency of this coating affects battery production efficiency. However, current coating efficiency is relatively low.

[0005] Summary of the Invention

[0006] The purpose of the embodiments of the present application is to provide a film coating device, which aims to improve the problem of low film coating efficiency in the related art.

[0007] An embodiment of the present application provides a film wrapping device, which includes a film preparation device, a cutting mechanism and a film wrapping device. The film preparation device includes a switching mechanism and multiple picking mechanisms. Multiple picking mechanisms are connected to the switching mechanism. The picking mechanism has a film preparation position and a film wrapping position. The switching mechanism is used to enable the picking mechanism to switch between the film preparation position and the film wrapping 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; the film wrapping device is used to wrap the insulating film picked up by the picking mechanism at the film wrapping position on the outer surface of the workpiece.

[0008] 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 at the coating position, other picking mechanisms can prepare the insulating film through 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, and the original serial action is changed to parallel, thereby improving the efficiency of coating.

[0009] 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 mechanism between the film preparation position and the film wrapping position when rotating around the first axis.

[0010] In the above technical solution, multiple pickup mechanisms are arranged on the first turret. As the first turret rotates, the multiple pickup mechanisms reciprocate between the film wrapping position and the film preparation position. By providing the first turret, the position switching of the multiple pickup mechanisms is simply and conveniently achieved, with low cost and high stability.

[0011] As an optional technical solution of an embodiment of the present application, the film wrapping equipment includes multiple cutting mechanisms, which 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.

[0012] In the above technical solution, multiple cutting mechanisms and pickup mechanisms are arranged in a one-to-one correspondence. When the first turret rotates, the cutting and pickup mechanisms rotate with the first turret, and their relative positions remain unchanged. As the first turret rotates, the insulating tape picked up by the pickup mechanism gradually increases. When the insulating tape reaches the required length, the cutting mechanism cuts the tape, forming an insulating film.

[0013] 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.

[0014] In the above technical solution, an adsorption member is provided to adsorb the insulating tape, and the adsorption member is not likely to cause damage to the insulating tape. In this way, the insulating film cut out by the cutting mechanism is of better quality, which is beneficial to improving the coating effect.

[0015] As an optional technical solution of an embodiment of the present application, the film preparation device includes a pressing mechanism, which is used to press the insulating tape onto the adsorption member.

[0016] 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.

[0017] As an optional technical solution of the embodiment of the present application, the pressing mechanism corresponds one-to-one with the adsorption member.

[0018] In the above technical solution, the pressing mechanism and the adsorption member are arranged in a one-to-one correspondence, so that the insulating tape adsorbed by each adsorption member can be pressed by the corresponding pressing mechanism, reducing the risk of the insulating tape detaching from the adsorption member. The pressing mechanism and the adsorption member can both be arranged on the first turret, so that the pressing mechanism and the adsorption member can rotate with the first turret, and the relative position of the pressing mechanism and the adsorption member remains unchanged. In this way, before the adsorption member reaches the coating position, the insulating tape or insulating film can be pressed against the adsorption member, making it difficult for the insulating tape or insulating film to detach from the adsorption member. In addition, since the relative position of the pressing mechanism and the adsorption member remains unchanged, it is not easy for the pressing mechanism to damage the insulating tape or insulating film when pressing the insulating tape or insulating film.

[0019] 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.

[0020] In the above technical solution, the pressing member is connected to the rocker arm, and the first driving mechanism can drive the rocker arm to swing, so that the pressing member is close to the adsorption member to press the insulating material strip against the adsorption member; or the pressing member is moved away from the adsorption member to loosen the insulating film, thereby facilitating the coating device to perform coating.

[0021] As an optional technical solution of the embodiment of the present application, the pressing member is a roller.

[0022] In the above technical solution, by using a roller as the pressing member, when the insulating tape and the pressing member move relative to each other, rolling friction is generated between the pressing member and the insulating tape, resulting in low frictional resistance and less damage to the insulating tape. Furthermore, the roller's circumference is generally soft and elastic, making contact with the insulating tape less likely to damage the insulating tape.

[0023] As an optional technical solution of an embodiment of the present application, the coating device includes a coating mechanism, which 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.

[0024] In this technical solution, one side of the insulating film is adhesive. During coating, the film is picked up by a pickup mechanism located at the coating position and can contact and adhere to the workpiece. The coating mechanism rotates the workpiece around its own axis, gradually wrapping the insulating film around and adhering it to the outer surface of the workpiece. This coating method is fast and efficient.

[0025] 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, and the plurality of the coating mechanisms are arranged on the second turret around a third axis. 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.

[0026] In this technical solution, one coating mechanism can coat one workpiece. Multiple coating mechanisms are located on the second turret. As the second turret rotates, the multiple coating mechanisms are sequentially switched to their working positions. This allows the next workpiece to be coated immediately after the previous one is finished, transforming the previously serial operations into parallel ones, thereby improving coating efficiency.

[0027] As an optional technical solution of an embodiment of the present application, the second turret includes a support platform for placing a support cup, the support cup is used to accommodate the workpiece, and a lifting mechanism is provided on the support platform, the lifting mechanism is used to lift the workpiece to separate the workpiece from the support cup and transfer it to the coating mechanism.

[0028] 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 providing 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, which then drives the workpiece to rotate, thereby coating the outer surface of the workpiece with an insulating film.

[0029] As an optional technical solution of the embodiment of the present application, a plurality of first bayonet holes are provided on the outer peripheral surface of the support platform, and the plurality of first bayonet holes are arranged around the third axis, and the first bayonet holes are used to accommodate the support cup.

[0030] 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 turn, 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.

[0031] 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 outside of the support platform, and the first retaining member is used to retain the cup in the first bayonet. The retaining member includes a first feed end and a first discharge end, and the support platform is configured to transport the cup from the first feed end to the first discharge end.

[0032] In the above technical solution, the first retaining member is provided to retain the cup within the first retaining member during rotation of the support member. The cup enters the first retaining member from the first inlet end, passes through the working position as the support member rotates, and is discharged from the first discharge end. Throughout this process, the cup is unlikely to escape from the first retaining member, thereby improving the stability of the coating device.

[0033] 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.

[0034] In the above technical solution, the lifting mechanism lifts the workpiece so that after the workpiece is released from the support cup, one end of the workpiece contacts the clamping member, thereby cooperating with the lifting mechanism and the clamping member to clamp the workpiece. The second drive mechanism can drive the clamping member to rotate, thereby driving the workpiece to rotate about its own axis, thereby coating the outer surface of the workpiece with the insulating film.

[0035] 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.

[0036] In this technical solution, when the lifting mechanism lifts the workpiece off the support cup, the workpiece contacts the clamping portion, compressing the elastic portion, thereby clamping the workpiece between the clamping portion and the lifting mechanism. The provision of the elastic portion imparts a certain degree of flexibility to the clamping member, making the workpiece less susceptible to damage during the clamping process.

[0037] 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.

[0038] 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 easily separated 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.

[0039] 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.

[0040] 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 separation of the workpiece.

[0041] 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.

[0042] In the above technical solution, by providing 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.

[0043] 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.

[0044] In the above technical solution, a smoothing member is provided to smooth the insulating film wrapped around the workpiece, thereby reducing the risk of wrinkling of the insulating film and improving the quality of the wrapping.

[0045] 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 is configured to adjust the distance between the smoothing member and the second turret in the radial direction of the second turret.

[0046] In the above technical solution, as the number of layers of insulating film applied to the workpiece increases, the force between the workpiece and the smoothing member increases. By providing a third drive mechanism to adjust the radial position of the smoothing member on the second turret, the smoothing member maintains contact with the insulating film on the workpiece until the insulating film is applied. This prevents the workpiece from being subjected to significant external force, potentially allowing it to escape from the coating and lifting mechanisms, while still allowing the insulating film to be smoothed.

[0047] As an optional technical solution of an embodiment of the present application, the wrapping equipment includes multiple unwinding mechanisms, which are used to unwind the insulating tape. The multiple unwinding mechanisms selectively provide the insulating tape to the picking mechanism.

[0048] In the above technical solution, the unwinding mechanism can unwind the insulating tape, thereby providing the insulating tape to the pickup mechanism. By providing multiple unwinding mechanisms, the multiple unwinding mechanisms selectively provide the insulating tape to the pickup mechanism. In this way, when the insulating tape of one unwinding mechanism is exhausted, the other unwinding mechanisms can be switched to continue providing the insulating tape to the pickup mechanism, thereby reducing downtime and improving film wrapping efficiency.

[0049] 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.

[0050] In the above technical solution, by slidably connecting the movable frame to the fixed frame, the fourth drive mechanism can drive the movable frame relative to the fixed frame toward the pickup mechanism, so that the insulating tape unwound by the unwinding roller can approach the pickup mechanism after passing through the guide, thereby providing the insulating tape to the pickup mechanism. The fourth drive mechanism can also drive the movable frame away from the pickup mechanism relative to the fixed frame, thereby stopping the supply of insulating tape to the pickup mechanism.

[0051] As an optional technical solution of an embodiment of the present application, the unwinding mechanism further includes a film pressing mechanism, which is used to press the insulating material tape led out by the guide member onto the picking mechanism.

[0052] 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 interruption of feeding, and ensuring the efficiency of film wrapping to a certain extent.

[0053] 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.

[0054] In the above technical solution, before the film coating equipment starts operating, the insulating tape needs to be placed on the unwinding roller and passed through the first and second rollers and guides in sequence, thereby preparing to feed the pickup mechanism. When the insulating tape on the unwinding roller is exhausted, the unwinding mechanism is switched to another unwinding mechanism to feed the pickup mechanism. The insulating tape upstream of the clamping mechanism is then manually cut to facilitate replacement with a new insulating tape. The new insulating tape is then joined to the old insulating tape held by the clamping mechanism, completing the installation of the new insulating tape without having to pass through the first and second rollers and guides in sequence, thereby increasing the convenience of replacing the insulating tape.

[0055] 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.

[0056] In the above technical solution, the detection mechanism is able to 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 wrapping to a certain extent.

[0057] As an optional technical solution of an embodiment of the present application, the waste collecting device includes a winding member, which is used to contact the insulating film and wind up the insulating film.

[0058] 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 winding the insulating film to peel off the insulating film and pick up the mechanism, which is simple and convenient.

[0059] 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.

[0060] In the above technical solution, the fifth driving mechanism is provided to drive the winding member to actively rotate, thereby more conveniently winding the insulating film onto the winding member.

[0061] 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 move closer to or away from the picking mechanism.

[0062] In the above technical solution, as the winding member continuously rewinds the problematic insulating film, the amount of insulating film on the winding member gradually increases, and the overall diameter of the winding member increases. To reduce the stress exerted by the winding member on the pickup mechanism, the sixth drive 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 between the winding member and 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 drive mechanism can drive the winding member away from the pickup mechanism, thereby reducing the risk of interference with the pickup mechanism.

[0063] As an optional technical solution of an embodiment of the present application, the coating device includes a loading mechanism, and the loading mechanism is used to transport the workpiece to the coating device.

[0064] In the above technical solution, by providing a loading mechanism, it is convenient to convey the workpiece to the coating device, which is beneficial to improving the degree of automation of the coating equipment.

[0066] In this technical solution, multiple second retaining members are provided on the outer circumference of the turntable, each of which can accommodate a cup. During the turntable's rotation, a second retaining member holds the cup within the second retaining member. The cup enters the second retaining member at the second inlet port and, as the turntable rotates, discharges the workpiece from the second outlet port to the coating device. Throughout this process, the cup is unlikely to disengage from the second retaining member, improving the stability of the coating device. Furthermore, the cup remains in contact with the turntable during transport, protecting the workpiece and reducing the risk of damage during transport.

[0067] As an optional technical solution of the embodiment of the present application, a plurality of second bayonet holes are provided on the turntable, and the plurality of second bayonet holes are arranged at intervals along the circumference of the turntable.

[0068] In the above technical solution, by providing a plurality of second bayonets, a plurality of trays can be transported when the turntable rotates, thereby improving the transport efficiency.

[0069] As an optional technical solution of an embodiment of the present application, the coating device includes a blanking mechanism, which is used to realize the blanking of the workpiece located in the coating device.

[0070] In the above technical solution, by providing a material unloading mechanism, it is convenient to unload the workpiece from the coating device, which is beneficial to improving the degree of automation of the coating equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Battery cells are generally divided into three types based on the packaging method: cylindrical battery cells, prismatic battery cells, and soft-pack battery cells, and the embodiments of this application do not limit this.

[0092] The battery referred to in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the battery referred to in this application may include a battery module or a battery pack. A battery generally includes a casing for enclosing one or more battery cells. The casing can, to a certain extent, prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0093] A battery cell includes an electrode assembly and an electrolyte. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. A battery cell primarily operates by the movement of metal ions between the positive and negative electrode sheets. The positive electrode sheet includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive electrode collector. The uncoated positive electrode collector protrudes from the coated positive electrode collector, serving as the positive tab. For lithium-ion batteries, for example, the positive electrode current collector can be made of aluminum, and the positive active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide. The negative electrode sheet includes a negative current collector and a negative active material layer.

To ensure that high currents can pass without fusing, multiple positive electrode tabs are stacked together, and multiple negative electrode tabs are stacked together. The separator can be made of materials such as PP (polypropylene) or PE (polyethylene). Furthermore, the electrode assembly can be a wound or laminated structure, but the embodiments of the present application are not limited thereto.

[0094] Currently, market developments indicate that batteries are increasingly being used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. As battery applications continue to expand, market demand is also growing.

[0095] During the battery production process, an insulating film needs to be coated on the 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.

[0096] In conventional technology, when coating the outer surface of a battery with an insulating film, the insulating film is typically prepared first and then applied to the workpiece. During this process, a new insulating film cannot be prepared in advance and must be prepared again after the film is applied. This serial production method is inefficient.

[0097] In view of this, an embodiment of the present application provides a film wrapping device, which includes a film preparation device, a cutting mechanism, and a film wrapping device. The film preparation device includes a switching mechanism and multiple pickup mechanisms, and the multiple pickup mechanisms are connected to the switching mechanism. The pickup mechanism has a film preparation position and a film wrapping position. The switching mechanism is used to enable the pickup mechanism to switch between the film preparation position and the film wrapping position. The pickup 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. The film wrapping device is used to wrap the insulating film picked up by the pickup mechanism at the film wrapping position onto the outer surface of the workpiece.

[0098] When the coating equipment 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, and the original serial action is changed to parallel, thereby improving the efficiency of coating.

[0099] The technical solution described in the embodiment of the present application is applicable to 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.

[0100] Please refer to Figures 1, 2, 3, and 4. Figure 1 is a schematic diagram of the structure of a film coating device 10 provided in some embodiments of the present application. Figure 2 is a schematic diagram of the structure of a film preparation device 11 provided in some embodiments of the present application. Figure 3 is an enlarged view of position A in Figure 2.

[0101] Figure 4 is a schematic diagram of the cooperation between the film preparation device 11 and the film wrapping device 12 provided in 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 enable the picking mechanism 111 to switch between the film preparation position and the film wrapping position. The picking mechanism 111 is used to pick up the 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.

[0102] The pickup mechanism 111 is used to pick up the insulating tape 23. It can be a gripper mechanism, a vacuum suction mechanism, or the like. The pickup mechanism 111 has a film preparation position and a film coating position. When in the film preparation position, the pickup mechanism 111 can pick up the insulating tape 23. When in the film coating position, the pickup mechanism 111 can cooperate with the film coating device 12 to coat the outer surface of the workpiece 22 with an insulating film.

[0103] The switching mechanism 112 is used to drive the pickup mechanism 111 to move, thereby switching the pickup mechanism 111 between the film preparation position and the film wrapping position. The switching mechanism 112 can be directly connected to the pickup mechanism 111 or indirectly connected to the pickup mechanism 111. For example, the switching mechanism 112 can be indirectly connected to the pickup mechanism 111 through an intermediate component.

[0104] The film preparation device 11 includes a plurality of picking mechanisms 111, each of which is 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 switches between a film preparation position and a film wrapping position.

[0105] 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 wrapping 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 wrapping position.

[0106] The cutting mechanism 19 is used to cut the insulating tape 23 to form an insulating film. When the pickup mechanism 111 switches from the film preparation position to the film wrapping position, the cutting mechanism 19 cuts the insulating tape 23. The pickup mechanism 111 continues to pick up the cut portion of the insulating tape 23 (insulating film) and transports the insulating film to the film wrapping position. The cutting mechanism 19 may include a cutter and a drive mechanism. The drive mechanism drives the cutter toward the insulating tape 23 to cut the insulating tape 23.

[0107] The film wrapping device 12 is a device for wrapping an insulating film on the outer surface of the workpiece 22. Optionally, the film wrapping device 12 includes a plurality of film wrapping jaws, which wrap the insulating film around the outer surface of the workpiece 22.

[0108] When the coating device 10 is working, multiple picking mechanisms 111 switch between the film preparation position and the coating position in turn. When one picking mechanism 111 is 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 original serial action is changed to parallel, thereby improving the efficiency of coating.

[0109] 1, 2, 3, and 4, in some embodiments, the switching mechanism 112 includes a first turret 1121, and a plurality of pickup mechanisms 111 are disposed about a first axis on the first turret 1121. The first turret 1121 is configured to switch the pickup mechanisms 111 between a film preparation position and a film wrapping position when rotating about the first axis.

[0110] The first axis is the rotational axis of the first turret 1121. The first turret 1121 is a rotating body that can rotate about the first axis. The phrase "multiple pickup mechanisms 111 are disposed about the first axis on the first turret 1121" can also be understood as multiple pickup mechanisms 111 being arranged circumferentially around the first turret 1121.

[0111] 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.

[0112] Multiple picking mechanisms 111 are provided on the first turret 1121. As the first turret 1121 rotates, the multiple picking mechanisms 111 reciprocate between the film wrapping position and the film preparation position. The provision of the first turret 1121 facilitates the switching of the positions of the multiple picking mechanisms 111, with low cost and high stability.

[0113] 1 , 2 , 3 and 4 , in some embodiments, the film wrapping 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 one to one with the picking mechanisms 111 .

[0114] The film wrapping 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 wrapping apparatus 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 cutting mechanisms 19 is equal to the number of picking mechanisms 111, and they are arranged corresponding to the picking mechanisms 111.

[0115] Multiple cutting mechanisms 19 can be arranged around a first axis on the first turret 1121, rotating with the first turret 1121. The multiple cutting mechanisms 19 are arranged in a one-to-one correspondence with the pickup mechanism 111. When the first turret 1121 rotates, the cutting mechanisms 19 and the pickup mechanism 111 rotate with the first turret 1121, and their relative positions remain unchanged. As the first turret 1121 rotates, the insulating tape 23 picked up by the pickup mechanism 111 gradually increases. When the insulating tape 23 reaches the required length, the cutting mechanism 19 cuts the insulating tape 23, forming an insulating film.

[0116] 1 , 2 , 3 and 4 , in some embodiments, the pickup mechanism 111 includes a suction member 1111 having suction holes 11111 , and the suction member 1111 is used to absorb the insulating tape 23 .

[0117] The pickup mechanism 111 is a vacuum suction mechanism. The pickup mechanism 111 includes a suction member 1111 in contact with the insulating tape 23. The suction member 1111 is provided with an air suction hole 11111. The air suction hole 11111 generates negative pressure by suction, thereby picking up the insulating tape 23 under the action of the pressure difference.

[0118] By arranging the adsorption member 1111 to adsorb the insulating material tape 23, the adsorption member 1111 is not likely to cause damage to the insulating material tape 23. In this way, the insulating film cut out by the cutting mechanism 19 is of better quality, which is conducive to improving the coating effect.

[0119] Referring to FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , in some embodiments, the film preparation device 11 includes a pressing mechanism 113 , which is used to press the insulating tape 23 onto the adsorption member 1111 .

[0120] The pressing mechanism 113 is used to press the insulating tape 23 against the adsorbent 1111. For example, the pressing mechanism 113 may include a linear drive and a pressing member 1132. 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 tape 23 against the adsorbent 1111.

[0121] By providing the 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 operational stability of the coating device 10 .

[0122] In some embodiments, the pressing mechanism 113 corresponds to the adsorption member 1111 on a one-to-one basis.

[0123] The number of the pressing mechanisms 113 and the adsorption members 1111 is the same, and the pressing mechanisms 113 are provided corresponding to the adsorption members 1111 , thereby facilitating the pressing of the insulating tape 23 onto the adsorption members 1111 .

[0124] 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 compressed by the corresponding clamping mechanism 113, reducing the risk of the insulating tape 23 detaching from the adsorbent 1111. The clamping mechanism 113 and the adsorbent 1111 can both be mounted on the first turret 1121. In this way, the clamping mechanism 113 and the adsorbent 1111 can rotate with the first turret 1121, and the relative positions of the clamping mechanism 113 and the adsorbent 1111 remain unchanged. Thus, before the adsorbent 1111 reaches the film wrapping position, the insulating tape 23 or insulating film can be compressed against the adsorbent 1111, preventing it from detaching from the adsorbent 1111. Furthermore, because the relative positions of the clamping mechanism 113 and the adsorbent 1111 remain unchanged, the clamping mechanism 113 is less likely to damage the insulating tape 23 or insulating film when compressing it.

[0125] Please refer to Figures 1, 2, 3 and 4. In some embodiments, the switching mechanism 112 includes a first turret 1121, and the adsorption member 1111 is connected to the first turret 1121. The first turret 1121 is configured to switch the adsorption member 1111 between the film preparation position and the film wrapping position when rotating around a first axis. The pressing mechanism 113 includes a rocker 1131, a pressing member 1132 and a first driving mechanism 1133. The rocker 1131 is rotatably arranged on the first turret 1121 around a second axis, and the second axis intersects the first axis. The pressing member 1132 is arranged on the rocker 1131. The first driving mechanism 1133 is connected to the rocker 1131 and the first turret 1121. The first driving mechanism 1133 is used to drive the rocker 1131 to swing around the second axis so that the pressing member 1132 presses the insulating tape 23 against the adsorption member 1111.

[0126] 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 wrapping position.

[0127] 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 can form an acute angle with the first axis or can be perpendicular to the first axis.

[0128] The pressing member 1132 and the first driving mechanism 1133 can be respectively disposed at both ends of the swing rod 1131. When the first driving mechanism 1133 drives the swing rod 1131 to swing, the pressing member 1132 can move closer to or further away from the suction member 1111. Referring to FIG3 , in the embodiment shown in FIG3 , 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 suction 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.

[0129] The first driving mechanism 1133 may include a linear driving member, which is connected to the rocker arm 1131. The linear driving member outputs linear motion, thereby driving the rocker arm 1131 to swing, so that the pressing member 1132 approaches or moves 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 rotary driving member and a transmission mechanism. The rotary driving member is connected to the rocker arm 1131 through the transmission mechanism. The rotary driving member outputs rotary motion, and the transmission mechanism converts the rotary motion into the swinging of the rocker arm 1131, so that the pressing member 1132 approaches or moves away from the adsorption member 1111. The rotary driving member may be a motor, an internal combustion engine, a rotary handle, etc. The transmission mechanism may be a screw-nut mechanism, a crank slider mechanism, etc.

[0130] Alternatively, the first drive mechanism 1133 may include a cam and a lifting rod, one end of the lifting rod being in contact with the cam, and the other end of the lifting rod being hinged to the swing arm 1131. The cam is rotatably mounted 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 arm 1131 to swing.

[0131] The pressing 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 pressing member 1132 is close to the adsorption member 1111 to press the insulating tape 23 against the adsorption member 1111; or the pressing member 1132 is away from the adsorption member 1111 to loosen the insulating film, thereby facilitating the coating device 12 to perform coating.

[0132] 1 , 2 , 3 and 4 , in some embodiments, the pressing member 1132 is a roller.

[0133] By using a roller as the pressing member 1132, when the insulating tape 23 and the pressing member 1132 move relative to each other, rolling friction is generated between the pressing member 1132 and the insulating tape 23, resulting in low frictional resistance and less likely to damage the insulating tape 23. Furthermore, the roller's circumference is generally soft and elastic, making contact with the insulating tape 23 less likely to damage the insulating tape 23.

[0134] 1, 4, and 5. FIG5 is a 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.

[0135] 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 .

[0136] The coating mechanism 121 is used to drive the workpiece 22 to rotate about 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 about its own axis, so that the insulating film is wrapped around the outer surface of the workpiece 22 to complete the coating.

[0137] One side of the insulating film is adhesive. During coating, the insulating film picked up by the pickup mechanism 111 at the coating position can contact the workpiece 22, thereby adhering to the workpiece 22. The coating mechanism 121 drives the workpiece 22 to rotate around its own axis, gradually wrapping the insulating film around and adhering it to the outer surface of the workpiece 22. This coating method is fast and efficient.

[0138] 1 , 4 , and 5 , in some embodiments, the coating device 12 includes a second turret 122 and a plurality of coating mechanisms 121. The plurality of coating mechanisms 121 are disposed about a third axis on the second turret 122. The second turret 122 is configured to switch the coating mechanisms 121 to a working position when rotating about the third axis. The coating mechanisms 121 are configured to coat the outer surface of the workpiece 22 with an insulating film in the working position.

[0139] The third axis is the rotational axis of the second turret 122. The second turret 122 is a rotating body capable of rotating about the third axis. The phrase "multiple film-wrapping mechanisms 121 are disposed about the third axis on the second turret 122" can also be understood as multiple film-wrapping mechanisms 121 being arranged circumferentially around the second turret 122.

[0140] When the second turret 122 rotates around the third axis, it can drive the multiple film wrapping mechanisms 121 to rotate, so that each film wrapping mechanism 121 cycles through the working position in sequence.

[0141] When the wrapping mechanism 121 passes the working position, the workpiece 22 can come into contact with the insulating film picked up by the picking mechanism 111 at the wrapping position. As the wrapping mechanism 121 drives the workpiece 22 to rotate, the insulating film is wrapped around the outer surface of the workpiece 22.

[0142] Each coating mechanism 121 can coat one workpiece 22. Multiple coating mechanisms 121 are located on the second turret 122. As the second turret 122 rotates, the multiple coating mechanisms 121 are sequentially switched to their working positions. This allows the coating of the next workpiece 22 to begin immediately after the previous workpiece 22 is coated, transforming the previously serial operations into parallel operations, thereby improving coating efficiency.

[0143] 1 , 4 , and 5 , in some embodiments, the second turret 122 includes a support platform 1221 for placing a cup 21, which is used to accommodate a workpiece 22. A lifting mechanism 123 is provided on the support platform 1221 for lifting the workpiece 22 to separate it from the cup 21 and transfer it to the coating mechanism 121.

[0144] The cup 21 is a cup structure for accommodating the workpiece 22. The lower end of the cup 21 is provided with a through hole for the lifting mechanism 123 to extend into, and the upper end of the cup 21 is provided with an opening for the workpiece 22 to enter and exit the cup 21. The inner side of the cup 21 can be formed with a flange to support the workpiece 22 and reduce the risk of friction between the workpiece 22 and the outside world.

[0145] The support platform 1221 supports the cup 21 and drives the cup 21 to rotate. A lifting mechanism 123 is mounted on the support platform 1221 and can lift the workpiece 22, thereby freeing the workpiece 22 from the cup 21 and allowing the insulating film to coat the workpiece 22. After freeing the cup 21, the workpiece 22 can engage the coating mechanism 121, driving it to rotate around its axis.

[0146] 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, thereby coating the outer surface of the workpiece 22 with an insulating film.

[0147] 1 , 4 and 5 , in some embodiments, a plurality of first bayonet holes 12211 are provided on the outer circumference of the support platform 1221 . 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 .

[0148] The first slots 12211 are notches provided on the outer circumference of the support platform 1221. A plurality of first slots 12211 are spaced apart along the circumference of the support platform 1221. The support cup 21 can be secured to the first slots 12211, thereby rotating as the support platform 1221 rotates.

[0149] By setting multiple 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 turn, 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.

[0150] 1 , 4 , and 5 , in some embodiments, the film coating device 12 includes a first retaining member 12212 disposed around the outside of the support platform 1221. The first retaining member 12212 is used to retain the cup 21 within the first retaining member 12211. The retaining member includes a first feed end and a first discharge end, and the support platform 1221 is configured to transport the cup 21 from the first feed end to the first discharge end.

[0151] The first retaining member 12212 may be an arc-shaped strip structure disposed around the outer circumference of the support platform 1221. Since the first retaining member 12212 is disposed around the outer side of the support platform 1221, the cup 21 located in the first retaining hole 12211 cannot be separated from the first retaining hole 12211 through the open end of the first retaining hole 12211, thereby retaining the cup 21 in the first retaining hole 12211.

[0152] The 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 rotates through the first feed end 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.

[0153] The first retaining member 12212 holds the cup 21 within the first retaining opening 12211 during rotation of the support member. The cup 21 enters the first retaining opening 12211 from the first inlet end, passes through the working position as the support member rotates, and is discharged from the first discharge end. Throughout this process, the cup 21 is unlikely to escape from the first retaining opening 12211, thereby enhancing the stability of the coating device 12.

[0154] 1 , 4 , and 5 , in some embodiments, the coating mechanism 121 includes a clamping member 1211 and a second driving mechanism 1212. The clamping member 1211 is disposed opposite the lifting mechanism 123 and is configured 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 and is configured to drive the clamping member 1211 to rotate, thereby rotating the workpiece 22 about its own axis.

[0155] The clamping member 1211 is used to clamp one end of the workpiece 22. The clamping member 1211 can be a claw structure or a flat plate structure. In this case, the surface of the clamping member 1211 can have a large friction force, thereby cooperating with the lifting mechanism 123 to clamp the workpiece 22.

[0156] 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.

[0157] The second drive mechanism 1212 may include a rotary drive member connected to the clamping member 1211, and the rotary drive member outputs a rotational motion, thereby driving the clamping member 1211 to rotate, thereby driving the workpiece 22 to rotate around its own axis. The rotary drive member may be a motor, an internal combustion engine, a rotary handle, etc. The second drive mechanism 1212 may also include a linear drive member and a transmission mechanism, and the linear drive member is connected to the clamping member 1211 via the transmission mechanism. The linear drive member outputs a linear motion, and the transmission mechanism converts the linear motion into a swinging motion of the clamping member 1211, thereby driving the workpiece 22 to rotate around its own axis. The linear drive member may be a linear electric cylinder, a linear oil cylinder, a linear pneumatic cylinder, etc. The transmission mechanism may be a screw-nut mechanism, a crank slider mechanism, etc.

[0158] Optionally, the second driving mechanism 1212 may include a rotation driving member and a transmission gear. The rotation driving member outputs a rotational motion, which is then transmitted by the transmission gear to drive the clamping member 1211 to rotate.

[0159] Optionally, in order to reduce the friction force of the lifting mechanism 123 on the workpiece 22 , the end of the lifting mechanism 123 that contacts the workpiece 22 may be set to a spherical surface.

[0160] 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. 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 about its own axis, so that the insulating film is applied to the outer surface of the workpiece 22.

[0161] 1 , 4 , and 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 configured 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.

[0162] The mounting portion 12113 is the portion of the clamping member 1211 that connects to the second drive mechanism 1212. The clamping portion 12111 is the portion of the clamping member 1211 that contacts the workpiece 22. Optionally, the clamping portion 12111 is in the shape of a cover. The clamping portion 12111 can be designed to conform to one end of the workpiece 22, thereby precisely covering the end of the workpiece 22 and enhancing the clamping force on the workpiece 22.

[0163] The elastic portion 12112 is disposed between the mounting portion 12113 and the clamping portion 12111. The elastic portion 12112 is capable of elastic deformation. When the lifting mechanism 123 lifts the workpiece 22, the elastic portion 12112 is gradually compressed, thereby forming a flexible connection between the clamping portion 12111 and the mounting portion 12113. This reduces the risk of damage to the workpiece 22 caused by rigid contact between the clamping portion 12111 and the workpiece 22. The elastic portion 12112 may be a spring, rubber, or the like.

[0164] When the lifting mechanism 123 lifts the workpiece 22 off the support cup 21, the workpiece 22 contacts the clamping portion 12111 and compresses the elastic portion 12112, thereby clamping the workpiece 22 between the clamping portion 12111 and the lifting mechanism 123. The provision of the elastic portion 12112 provides a certain degree of flexibility to the clamping member 1211, making the workpiece 22 less susceptible to damage during the clamping process.

[0165] 1 , 4 and 5 , in some embodiments, the coating device 12 includes a holding mechanism 124 disposed on a support platform 1221 . The holding mechanism 124 is used to hold the workpiece 22 between the lifting mechanism 123 and the coating mechanism 121 .

[0166] 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, thereby limiting the workpiece 22.

[0167] By setting up a holding mechanism 124, the workpiece 22 is held 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.

[0168] 1 , 4 , and 5 , in 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 configured to contact the workpiece 22 and is configured to rotate about its own axis when the coating mechanism 121 drives the workpiece 22 to rotate.

[0169] The mounting base 1241 is the mounting base for the limiting roller 1242, and the mounting base 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.

[0170] Optionally, the rotation axis of the limiting roller 1242 is parallel to the third axis.

[0171] 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.

[0172] 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.

[0173] 1 , 4 and 5 , in some embodiments, the holding mechanism 124 includes a plurality of limiting rollers 1242 disposed around the workpiece 22 .

[0174] The holding mechanism 124 includes a plurality of limiting rollers 1242 disposed around the circumference of the workpiece 22. Since the workpiece 22 is accommodated in the support cup 21, which is secured to the first retaining opening 12211, the plurality of limiting rollers 1242 may also be disposed around the circumference of the first retaining opening 12211.

[0175] 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.

[0176] 1 , 4 and 5 , in some embodiments, the coating device 12 includes a smoothing mechanism 125 , 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 .

[0177] Smoothing element 1251 is a component that contacts the insulating film covering workpiece 22. After the insulating film is bonded to workpiece 22, smoothing element 1251 is placed in contact with the insulating film covering workpiece 22 to ensure better adhesion of the subsequent insulating film to the workpiece 22 and reduce the risk of subsequent insulating film wrinkling. This allows the insulating film to be smoothed by smoothing element 1251 as workpiece 22 rotates before being wound onto the workpiece 22, resulting in improved film quality.

[0178] By providing the smoothing member 1251 , the insulating film wrapped around the workpiece 22 is smoothed, thereby reducing the risk of the insulating film wrinkling and improving the quality of the wrapping.

[0179] Please refer to Figures 1, 4 and 5. In some embodiments, the smoothing mechanism 125 also includes a third driving mechanism 1252, which is connected to the smoothing member 1251. The third driving mechanism 1252 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.

[0180] The third drive mechanism 1252 may include a linear drive member connected to the smoothing member 1251. The linear drive member outputs linear motion, thereby driving the smoothing member 1251 toward or away from the second turret 122 to adjust the radial distance between the smoothing member 1251 and the second turret 122. The linear drive member may be a linear electric cylinder, a linear oil cylinder, a linear air cylinder, etc. The third drive mechanism 1252 may also include a rotary drive member and a transmission mechanism. The rotary drive member is connected to the smoothing member 1251 via the transmission mechanism. The rotary drive member outputs rotary motion, and the transmission mechanism converts the rotary motion into linear motion of the smoothing member 1251 to adjust the radial distance between the smoothing member 1251 and the second turret 122. The rotary drive member may be a motor, an internal combustion engine, a rotary handle, etc. The transmission mechanism may be a screw-nut mechanism, a crank-slider mechanism, etc.

[0181] As the number of insulating film layers applied to the workpiece 22 increases, the force between the workpiece 22 and the smoothing member 1251 increases. By providing a third drive mechanism 1252 to adjust the radial position of the smoothing member 1251 relative to the second turret 122, the smoothing member 1251 maintains contact with the insulating film on the workpiece 22 until the insulating film coating is complete. This prevents the workpiece 22 from being subjected to significant external force, potentially allowing it to separate from the coating mechanism 121 and the lifting mechanism 123, while still maintaining the smoothing effect on the insulating film.

[0182] Please refer to Figures 1 and 5. Figure 5 is a schematic diagram of the structure of a film wrapping device 12 provided in some embodiments of the present application. In some embodiments, the film wrapping device 10 includes multiple unwinding mechanisms 13, each of which is used to unwind an insulating tape 23. Each of the multiple unwinding mechanisms 13 selectively provides the insulating tape 23 to the pickup mechanism 111.

[0183] The unwinding mechanism 13 is a mechanism for unwinding the insulating tape 23. The insulating tape 23 unwound by the unwinding mechanism 13 can be picked up by the picking mechanism 111 located at the film preparation position.

[0184] The film wrapping device 10 includes multiple unwinding mechanisms 13. During operation, only one of the multiple unwinding mechanisms 13 provides the insulating tape 23 to the pickup mechanism 111. The other unwinding mechanisms 13 are in a standby state. When the insulating tape 23 of the operating unwinding mechanism 13 is completely unwound, the other unwinding mechanisms 13 can be switched to continue providing the insulating tape 23 to the pickup mechanism 111.

[0185] The unwinding mechanism 13 can unwind the insulating tape 23, thereby providing the insulating tape 23 to the pickup mechanism 111. By providing multiple unwinding mechanisms 13, the multiple unwinding mechanisms 13 selectively provide the insulating tape 23 to the pickup mechanism 111. In this way, when the insulating tape 23 of one unwinding mechanism 13 is exhausted, another unwinding mechanism 13 can be switched to continue providing the insulating tape 23 to the pickup mechanism 111, thereby reducing downtime and improving film wrapping efficiency.

[0186] Referring to Figures 1 and 5, in some embodiments, the unwinding mechanism 13 includes an unwinding roller 131, a fixed frame 132, a movable frame 133, and a fourth drive mechanism 135. The unwinding roller 131 is used to unwind the insulating tape 23 and is mounted on the fixed frame 132. The movable frame 133 is provided with a guide 134, which is used to guide the insulating tape 23 to the pickup mechanism 111. The movable frame 133 is slidably connected to the fixed frame 132. The fourth drive mechanism 135 is connected to the fixed frame 132 and the movable frame 133. The fourth drive mechanism 135 is used to drive the movable frame 133 to slide relative to the fixed frame 132, thereby moving the guide 134 closer to or farther from the pickup mechanism 111.

[0187] 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.

[0188] The fixing frame 132 is an inactive mounting frame relative to the ground or the machine. The unwinding roller 131 is mounted on the fixing frame 132 so that the unwinding roller 131 can stably unwind the insulating tape 23.

[0189] The movable frame 133 is a frame structure that is movable relative to the fixed frame 132. The movable frame 133 is slidably connected to the fixed frame 132. The fourth drive mechanism 135 can be mounted on the fixed frame 132. The output end of the fourth drive mechanism 135 can be connected to the movable frame 133. When the fourth drive mechanism 135 is activated, it can drive the movable frame 133 to slide relative to the fixed frame 132.

[0190] The fourth drive mechanism 135 may include a linear drive member, which is mounted on the fixed frame 132. The output end of the linear drive member is connected to the movable frame 133. The linear drive member outputs linear motion, thereby driving the movable frame 133 to slide relative to the fixed frame 132, so that the guide member 134 moves closer to or away from the pickup mechanism 111. The linear drive member may be a linear electric cylinder, a linear oil cylinder, a linear air cylinder, etc. The fourth drive mechanism 135 may also include a rotary drive member and a transmission mechanism. The rotary drive member is mounted on the fixed frame 132, and the rotary drive member is connected to the movable frame 133 via the transmission mechanism. The rotary drive member outputs rotational motion, and the transmission mechanism converts the rotational motion into movement of the movable frame 133, so that the guide member 134 moves closer to or away from the pickup mechanism 111. The rotary drive 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.

[0191] The guide member 134 is provided on the movable frame 133 and is used to guide the insulating tape 23 to the pickup mechanism 111. Optionally, the guide member 134 is a guide plate extending toward the pickup mechanism 111, and the insulating tape 23 is guided to the pickup mechanism 111 via the guide plate.

[0192] By slidably connecting the movable frame 133 to the fixed frame 132, the fourth driving mechanism 135 can drive the movable frame 133 toward the pickup mechanism 111 relative to the fixed frame 132, so that the insulating tape 23 unwound by the unwinding roller 131 can approach the pickup mechanism 111 after passing through the guide 134, thereby providing the insulating tape 23 to the pickup mechanism 111. The fourth driving mechanism 135 can also drive the movable frame 133 away from the pickup mechanism 111 relative to the fixed frame 132, thereby stopping the supply of the insulating tape 23 to the pickup mechanism 111.

[0193] Optionally, one side of the insulating tape 23 is sticky or provided with an adhesive layer. To protect the stickiness or adhesive layer of the insulating tape 23 to a certain extent, a protective film 24 is provided on the sticky side or adhesive layer of the insulating tape 23. The unwinding mechanism 13 also includes a winding roller 1331 for winding up the protective film 24. The protective film 24 and the insulating tape 23 are separated on the guide 134. The protective film 24 is wound by the winding roller 1331, and the insulating tape 23 is fed to the pickup mechanism 111. The provision of the winding roller 1331 allows the protective film 24 to be automatically peeled off the insulating tape 23, thereby improving the degree of automation.

[0194] In addition, the unwinding mechanism 13 may further include a deviation correction component to detect and correct the deviation of the insulating tape 23 .

[0195] 1 and 5 , in some embodiments, the unwinding mechanism 13 further includes a film pressing mechanism 136 , which is used to press the insulating tape 23 led out of the guide 134 onto the picking mechanism 111 .

[0196] The film pressing mechanism 136 may include a film pressing driver and a film pressing member. The film pressing driver is connected to the film pressing member and is used to drive the film pressing member toward the pickup mechanism 111, thereby pressing the insulating tape 23 onto the pickup mechanism 111. The film pressing driver is also used to drive the film pressing member away from the pickup mechanism 111, thereby releasing the insulating tape 23. The film pressing driver may be a linear cylinder, a linear electric cylinder, a linear hydraulic cylinder, etc.

[0197] 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.

[0198] The film pressing mechanism 136 can be provided in a one-to-one correspondence with the unwinding mechanism 13 .

[0199] By setting up a film pressing mechanism 136, the insulating tape 23 led out by the guide 134 is pressed onto the picking mechanism 111, so that the unwinding mechanism 13 can provide the insulating tape 23 to the picking mechanism 111 more stably, reducing the risk of shutdown due to feed interruption, and ensuring the efficiency of film wrapping to a certain extent.

[0200] Referring to Figures 1 and 5 , in some embodiments, the unwinding mechanism 13 includes a first roller 137 and a second roller 138. The first roller 137 is disposed on a fixed frame 132, and the second roller 138 is disposed on a 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 release the insulating tape 23.

[0201] The first roller 137 is a roller structure mounted on the fixed frame 132. The second roller 138 is a roller structure mounted on the movable frame 133. When the film coating apparatus 10 is used for the first time, the insulating tape 23 needs to be passed through or wrapped around the first roller 137, the clamping mechanism 139, the second roller 138, and the guide 134 in sequence.

[0202] The clamping mechanism 139 is used to clamp or loosen the insulating tape 23. The clamping mechanism 139 may include a first clamping arm and a second clamping arm. 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 moves away from the second clamping arm, the clamping mechanism 139 loosens the insulating tape 23.

[0203] Before the film coating device 10 operates, the insulating tape 23 needs to be placed on the unwinding roller 131 and passed through the first roller 137, the second roller 138, and the guide 134 in sequence, thereby preparing to feed the pickup mechanism 111. When the insulating tape 23 on the unwinding roller 131 is exhausted, the unwinding mechanism 13 is switched to another unwinding mechanism 13 to feed the pickup mechanism 111. The insulating tape 23 upstream of the clamping mechanism 139 is then manually cut to facilitate replacement with a new insulating tape 23. The new insulating tape 23 is then joined to the old insulating tape 23 held by the clamping mechanism 139, completing the installation of the new insulating tape 23 without having to pass through the first roller 137, the second roller 138, and the guide 134 in sequence, thereby increasing the convenience of replacing the insulating tape 23.

[0204] Please refer to Figure 7, which is a simplified schematic diagram of an unwinding mechanism 13 and a film preparation device 11 according to some embodiments of the present application. In the embodiment shown in Figure 7, the unwinding mechanism 13 on the left side supplies the insulating tape 23 to the pickup mechanism 111 of the film preparation device 11.

[0205] Please refer to Figure 8, which is a simplified schematic diagram illustrating the separation of the unwinding mechanism 13 and the film preparation device 11 according to some embodiments of the present application. When the insulating tape 23 of the left unwinding mechanism 13 is finished unwinding, the film pressing mechanism 136 corresponding to the left unwinding mechanism 13 first releases the insulating tape 23. The fourth driving mechanism 135 of the left unwinding mechanism 13 then drives the movable frame 133 away from the pickup mechanism 111 relative to the fixed frame 132.

[0206] Please refer to Figure 9, which is a simplified schematic diagram of another unwinding mechanism 13 and the film preparation device 11 provided in some embodiments of the present application. The fourth drive mechanism 135 of the unwinding mechanism 13 on the right side drives the movable frame 133 relative to the fixed frame 132 to approach the pickup mechanism 111. 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 pickup mechanism 111. In this way, the two unwinding mechanisms 13 are switched. While the unwinding mechanism 13 on the right side is unwinding, the insulating tape roll can be reinstalled on the unwinding mechanism 13 on the left side.

[0207] Please refer to Figures 1 and 10. Figure 10 is a schematic diagram illustrating the coordination between the film preparation device 11 and the waste collection device 142 according to some embodiments of the present application. In some embodiments, the film coating apparatus 10 further includes a detection mechanism 141 and a waste collection device 142. The detection mechanism 141 is configured to detect the insulating film. The waste collection device 142 is electrically connected to the detection mechanism 141 and responds to the detection mechanism 141 to peel the insulating film off the pickup mechanism 111.

[0208] Inspection mechanism 141 is used to inspect the insulating film to confirm whether it meets the requirements. For example, inspection mechanism 141 can inspect the appearance of the insulating film to confirm whether it is wrinkled. Inspection mechanism 141 can be an industrial camera that can confirm whether the insulating film meets the requirements by taking pictures and comparing them.

[0209] 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 with this joint to the picking mechanism 111 .

[0210] 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 arm, and the defective insulating film is peeled off from the picking mechanism 111 by the robot arm.

[0211] The scrap collecting device 142 can be electrically connected to the detection mechanism 141 directly or through an intermediate component. For example, the scrap collecting device 142 is electrically connected to the detection mechanism 141 via a controller. When the detection mechanism 141 detects a defective insulating film, the controller controls the scrap collecting device 142 to remove the defective insulating film from the device of the pickup mechanism 111.

[0212] 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 wrapping the problematic insulating film onto the workpiece 22 and ensuring the quality of the wrapping to a certain extent.

[0213] 1 and 10 , in some embodiments, the waste collecting device 142 includes a winding member 1421 , and the winding member 1421 is configured to contact the insulating film and wind the insulating film.

[0214] The winding member 1421 can be configured 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 due to overpressure.

[0215] 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 off the insulating film from the picking mechanism 111, which is simple and convenient.

[0216] 1 and 10 , in some embodiments, the waste collecting device 142 further includes a fifth driving mechanism 1422 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 .

[0217] 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, thereby driving 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 rotation of the winding member 1421, so that the insulating film is wound around 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.

[0218] By providing the fifth driving mechanism 1422 , the winding member 1421 can be driven to actively rotate, thereby more conveniently winding the insulating film onto the winding member 1421 .

[0219] 1 and 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 configured to drive the winding member 1421 toward or away from the picking mechanism 111 .

[0220] The sixth driving mechanism 1423 is connected to the winding member 1421 and is used to drive the winding member 1421 toward or away from the pickup mechanism 111. The sixth driving mechanism 1423 can drive the winding member 1421 to move, thereby causing the winding member 1421 to move toward or away from the pickup mechanism 111. The sixth driving mechanism 1423 can also drive the winding member 1421 to swing or rotate, thereby causing the winding member 1421 to move toward or away from the pickup mechanism 111.

[0221] The sixth driving mechanism 1423 may include a linear driving member, which is connected to the winding member 1421. The linear driving member outputs 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 rotary driving member and a transmission mechanism. The rotary driving member is connected to the winding member 1421 through the transmission mechanism. The rotary driving member outputs rotary motion, and the transmission mechanism converts the rotary motion into movement of the winding member 1421, so that the winding member 1421 is close to or away from the picking mechanism 111. The rotary driving member may be a motor, an internal combustion engine, a rotary handle, etc. The transmission mechanism may be a screw-nut mechanism, a crank slider mechanism, etc.

[0222] As the winding member 1421 continuously rewinds the problematic insulating film, the amount of insulating film on the winding member 1421 gradually increases, and the overall diameter of the winding member 1421 increases. To reduce the stress of the winding member 1421 on the pickup mechanism 111, the sixth driving mechanism 1423 can adjust the distance between the winding member 1421 and the pickup mechanism 111 so that the winding member 1421 can approach the pickup mechanism 111 to rewind the problematic insulating film, and control the distance from the pickup mechanism 111 during rewinding, thereby reducing the stress on the pickup mechanism 111. In addition, when there is no need to rewind the insulating film, the sixth driving mechanism 1423 can drive the winding member 1421 away from the pickup mechanism 111, thereby reducing the risk of interference with the pickup mechanism 111.

[0223] 1 and 11 , FIG11 is a schematic diagram illustrating the cooperation between the film coating device 12 and the loading mechanism 15 provided in some embodiments of the present application. In some embodiments, the film coating device 12 includes the loading mechanism 15 , which is used to transport the workpiece 22 to the film coating device 12 .

[0224] The loading mechanism 15 is a mechanism for loading the workpiece 22 onto the coating device 12. The loading mechanism 15 may include a conveyor belt, a pull belt, and the like.

[0225] By providing the loading mechanism 15 , it is convenient to convey the workpiece 22 to the coating device 12 , which is beneficial to improving the degree of automation of the coating equipment 10 .

[0226] Referring to Figures 1 and 11 , in some embodiments, the loading mechanism 15 includes a turntable 151 for placing a cup 21 and a second retaining member 152. The cup 21 is used to hold the workpiece 22. A second retaining member 1511 is provided on the outer periphery of the turntable 151. The second retaining member 152 is disposed around the outer periphery of the turntable 151 and is used to retain the cup 21 within the second retaining member 1511. The retaining member includes a second inlet end and a second outlet end. The turntable 151 is configured to transport the cup 21 from the second inlet end to the second outlet end, and the coating device 12 receives the cup 21 at the second outlet end.

[0227] The second slot 1511 is a notch provided on the outside of the rotating disk 151. The support cup 21 can be secured to the second slot 1511, thereby rotating as the rotating disk 151 rotates.

[0228] 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 in the second retaining hole 1511 cannot be separated from the second retaining hole 1511 through the open end of the second retaining hole 1511, thereby retaining the cup 21 in the second retaining hole 1511.

[0229] 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 rotates through the second feed end to 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.

[0230] By providing multiple second retaining openings 1511 on the outer circumference of the turntable 151, each second retaining opening 1511 can accommodate a cup 21. As the turntable 151 rotates, the second retaining member 152 holds the cup 21 within the second retaining opening 1511. The cup 21 enters the second retaining opening 1511 from the second inlet end. As the turntable 151 rotates, the workpiece 22 is discharged from the second outlet end to the film coating device 12. Throughout this process, the cup 21 is unlikely to escape from the second retaining opening 1511, thereby improving the stability of the film coating device 12. Furthermore, during the conveying process, the cup 21 is always in contact with the turntable 151, protecting the workpiece 22 from the cup 21, thereby reducing the risk of damage to the workpiece 22 during conveyance.

[0231] 1 and 11 , in some embodiments, a plurality of second bayonet holes 1511 are provided on the turntable 151 , and the plurality of second bayonet holes 1511 are spaced apart along the circumference of the turntable 151 .

[0232] By providing a plurality of second bayonet ports 1511 , a plurality of tray cups 21 can be transported when the turntable 151 rotates, thereby improving the transport efficiency.

[0233] Referring again to FIG. 1 , in some embodiments, the film coating apparatus 10 includes a material unloading mechanism 16 , which is used to unload the workpiece 22 located at the film coating device 12 .

[0234] 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.

[0235] 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 degree of automation of the coating equipment 10 .

[0236] Referring to Figure 1 , in some embodiments, the film coating apparatus 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, which verifies the workpiece 22 (verifying various indicators of the workpiece 22 by scanning a QR code on the workpiece 22). When the workpiece 22 passes verification by the verification mechanism 17, the first conveying mechanism 153 conveys the workpiece 22 to the loading mechanism 15. If the workpiece 22 fails verification, the third conveying mechanism conveys the workpiece 22 to a waste bin.

[0237] The first conveying mechanism 153, the second conveying mechanism 18 and the third conveying mechanism may include conveyor belts, pull belts, etc., and may also have the same structure as the feeding mechanism 15, which will not be repeated here.

[0238] In the present application, the driving gear provided on the second turret 122 can be engaged 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 by a driving force to rotate.

[0239] 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 this insulating tape 23 is coated on the workpiece 22, the connection strength with the workpiece 22 is higher and the connection stability is better.

[0240] The working process of the coating device 10 provided in the embodiment of the present application is as follows:

[0241] First, the second conveying mechanism 18 conveys the workpiece 22 to the verification mechanism 17, which verifies the workpiece 22. If the workpiece 22 passes the verification by the verification mechanism 17, the first conveying mechanism 153 conveys the workpiece 22 to the loading mechanism 15. If the workpiece 22 fails the verification, the third conveying mechanism conveys the workpiece 22 to the waste box.

[0242] The loading mechanism 15 transfers the workpiece 22 to the coating device 12 . The workpiece 22 is sequentially clamped into the first clamping opening 12211 of the support table 1221 and guided to the working position as the first turret 1121 rotates.

[0243] As the workpiece 22 is transported to the coating device 12, the unwinding mechanism 13 unwinds the insulating tape 23. The pickup mechanism 111 receives the insulating tape 23 and transports it from the film preparation position to the coating position. During this process, the insulating tape 23 gradually and completely covers the adsorbent 1111. The film pressing mechanism 136 presses the insulating tape 23 onto the adsorbent 1111. The cutting mechanism 19 then cuts the insulating tape 23 to form an insulating film.

[0244] When the pick-up mechanism 111 reaches the coating position, the coating mechanism 121 also reaches its operating position. At this point, the lifting mechanism 123 ejects the workpiece 22 from 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 about its axis and the smoothing member 1251 presses the insulating film against the workpiece 22, the insulating film gradually wraps around the workpiece 22, completing the coating. Subsequently, as the second turret 122 continues to rotate, the coated workpiece 22 is unloaded from the unloading mechanism 16.

[0245] In some embodiments, the film wrapping device 10 includes two unwinding mechanisms 13, each of which selectively provides the insulating tape 23 to the pickup mechanism 111. When the first unwinding mechanism 13 finishes unwinding the insulating tape 23, the film pressing mechanism 136 corresponding to the first unwinding mechanism 13 first releases the insulating tape 23. The fourth drive mechanism 135 of the first unwinding mechanism 13 drives the movable frame 133 away from the pickup mechanism 111 relative to the fixed frame 132. The fourth drive mechanism 135 of the second unwinding mechanism 13 drives the movable frame 133 toward the pickup mechanism 111 relative to the fixed frame 132. 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 pickup mechanism 111. In this way, the two unwinding mechanisms 13 are switched. While the second unwinding mechanism 13 is unwinding, the insulating tape roll can be reinstalled on the first unwinding mechanism 13.

[0246] 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 wrinkles or other problems with the insulating film (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.

[0247] According to some embodiments of the present application, please refer to Figures 1 to 11.

[0248] An embodiment of the present application provides a film coating device 10, which includes a film preparation device 11, a cutting mechanism 19, and a film coating 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 coating position. The switching mechanism 112 is used to enable the picking mechanism 111 to switch between the film preparation position and the film coating position. The picking mechanism 111 is used to pick up the 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 coating device 12 is used to coat the insulating film picked up by the picking mechanism 111 at the film coating position on the outer surface of the workpiece 22. When the coating device 10 is working, multiple picking mechanisms 111 switch between the film preparation position and the coating position in turn. When one picking mechanism 111 is 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 original serial action is changed to parallel, thereby improving the efficiency of coating.

[0249] The switching mechanism 112 includes a first turret 1121. Multiple pickup mechanisms 111 are disposed on the first turret 1121 around a first axis. The first turret 1121 is configured to switch between a film preparation position and a film wrapping position when rotating about the first axis. Multiple pickup mechanisms 111 are disposed on the first turret 1121. As the first turret 1121 rotates, the multiple pickup mechanisms 111 reciprocate between the film wrapping position and the film preparation position. The provision of the first turret 1121 facilitates simple and convenient position switching of the multiple pickup mechanisms 111, resulting in low cost and high stability.

[0250] The coating device 12 includes a second turret 122 and multiple coating mechanisms 121. The multiple coating mechanisms 121 are arranged 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 about the third axis. The coating mechanisms 121 are used to drive the workpiece 22 to rotate around its own axis in the working position so that the insulating film is coated on the outer surface of the workpiece 22. Each coating mechanism 121 can coat a corresponding workpiece 22. Multiple coating mechanisms 121 are arranged on the second turret 122. As the second turret 122 rotates, the multiple 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, turning the originally serial operation into a parallel operation, thereby improving the coating efficiency. One side of the insulating film is sticky. During coating, the insulating film picked up by the pickup mechanism 111 at the coating position can contact the workpiece 22, thereby adhering 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 adhering it to the outer surface of the workpiece 22. This coating method has a fast coating speed and high efficiency.

[0251] 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 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, thereby coating the outer surface of the workpiece 22 with an insulating film.

[0252] The outer circumference of the support platform 1221 is provided with a plurality of first slots 12211, which are arranged around the third axis. The first slots 12211 are used to accommodate the support cup 21. 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 within the first slots 12211. The retaining member includes a first feed end and a first discharge end. The support platform 1221 is configured to transport the support cup 21 from the first feed end to the first discharge end. By providing a plurality of first bayonet holes 12211 on the outer circumferential surface of the support platform 1221, each first bayonet hole 12211 can accommodate a support cup 21. As the second turret 122 rotates, the first bayonet holes 12211 sequentially pass through the working position, thereby transporting 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 workpiece 22 with the insulating film. By providing a first retaining member 12212, the support cup 21 is retained in the first bayonet hole 12211 during the rotation of the support member. The support cup 21 enters the first bayonet hole 12211 from the first feed end, passes through the working position as the support seat rotates, and is discharged from the first discharge end. During the entire process, the support cup 21 is not easily separated from the first bayonet hole 12211, thereby improving the stability of the coating device 12.

[0253] The film wrapping device 10 includes multiple unwinding mechanisms 13 for unwinding insulating tape 23. Each of the unwinding mechanisms 13 selectively provides insulating tape 23 to a pickup mechanism 111. The unwinding mechanisms 13 include an unwinding roller 131, a fixed frame 132, a movable frame 133, and a fourth drive mechanism 135. The unwinding roller 131 is used to unwind the insulating tape 23. The unwinding roller 131 is mounted on the fixed frame 132. The movable frame 133 is provided with a guide 134 for guiding the insulating tape 23 to the pickup mechanism 111. The movable frame 133 is slidably connected to the fixed frame 132. A fourth drive mechanism 135 is connected to the fixed frame 132 and the movable frame 133. The fourth drive mechanism 135 is used to drive the movable frame 133 to slide relative to the fixed frame 132, thereby moving the guide 134 toward or away from the pickup mechanism 111. The unwinding mechanism 13 is capable of unwinding the insulating tape 23, thereby providing the insulating tape 23 to the pickup mechanism 111. By providing multiple unwinding mechanisms 13, the multiple unwinding mechanisms 13 selectively provide the insulating tape 23 to the pickup mechanism 111. Thus, when the insulating tape 23 of one unwinding mechanism 13 is exhausted, another unwinding mechanism 13 can be switched to continue providing the insulating tape 23 to the pickup mechanism 111, thereby reducing downtime and improving film coating efficiency. By slidably connecting the movable frame 133 to the fixed frame 132, the fourth drive mechanism 135 can drive the movable frame 133 relative to the fixed frame 132 to approach the pickup mechanism 111, so that the insulating tape 23 unwound by the unwinding roller 131 can approach the pickup mechanism 111 after passing through the guide 134, thereby providing the insulating tape 23 to the pickup 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 the supply of the insulating tape 23 to the picking mechanism 111 .

[0254] The film wrapping device 10 also includes a detection mechanism 141 and a waste material collection device 142. The detection mechanism 141 is used to detect the insulating film. The waste material collection device 142 is electrically connected to the detection mechanism 141 and responds to the detection mechanism 141 to peel the insulating film off the pickup mechanism 111. The waste material collection device 142 includes a winding member 1421, which is used to contact and wind the insulating film. The waste material collection device 142 also includes a fifth drive mechanism 1422, which is connected to the winding member 1421 and 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 collection device 142 also includes a sixth drive mechanism 1423, which is connected to the winding member 1421 and is used to drive the winding member 1421 toward or away from the pickup mechanism 111. The detection mechanism 141 is capable of inspecting the insulating film. When the detection mechanism 141 detects wrinkles or other problems with the insulating film, the waste collection device 142 peels the problematic insulating film off the pickup mechanism 111, thereby reducing the risk of the problematic insulating film being wrapped around the workpiece 22 and, to a certain extent, ensuring the quality of the wrapping. When the detection mechanism 141 detects wrinkles or other problems with the insulating film, the winding member 1421 of the waste collection device 142 can contact the insulating film, allowing the insulating film to adhere to the winding member 1421, thereby reeling the insulating film and peeling it off the pickup mechanism 111, which is simple and convenient. The provision of a fifth drive mechanism 1422 can drive the winding member 1421 to actively rotate, making it more convenient to reel the insulating film onto the winding member 1421. As the winding member 1421 continuously rewinds the problematic insulating film, the amount of insulating film on the winding member 1421 gradually increases, and the overall diameter of the winding member 1421 increases. To reduce the stress of the winding member 1421 on the pickup mechanism 111, the sixth driving mechanism 1423 can adjust the distance between the winding member 1421 and the pickup mechanism 111 so that the winding member 1421 can approach the pickup mechanism 111 to rewind the problematic insulating film, and control the distance from the pickup mechanism 111 during rewinding, thereby reducing the stress on the pickup mechanism 111. In addition, when there is no need to rewind the insulating film, the sixth driving mechanism 1423 can drive the winding member 1421 away from the pickup mechanism 111, thereby reducing the risk of interference with the pickup mechanism 111.

[0255] 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 retaining member 152. The cup 21 is used to accommodate the workpiece 22. The outer periphery of the turntable 151 is provided with a second retaining member 1511. The second retaining member 152 is arranged around the outer side of the turntable 151 and is used to retain the cup 21 within the second retaining member 1511. The retaining member 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. The coating device 12 receives the cup 21 at the second discharge end. The provision of the loading mechanism 15 facilitates the transport of the workpiece 22 to the coating device 12, which helps to improve the degree of automation of the coating equipment 10. By providing a second retaining opening 1511 on the outer circumference of the turntable 151, the second retaining opening 1511 can accommodate the cup 21. During the rotation of the turntable 151, the second retaining member 152 holds the cup 21 within the second retaining opening 1511. The cup 21 enters the second retaining opening 1511 from the second inlet end. As the turntable 151 rotates, the workpiece 22 is discharged from the second outlet end to the film coating device 12. Throughout this process, the cup 21 is unlikely to escape from the second retaining opening 1511, thereby improving the stability of the film coating device 12. Furthermore, 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 conveying.
