[0029] First aspect, see Figures 1 to 3The application provides a pressing device 100, which comprises a supporting plate 10, a fixing frame 20 and a pressing assembly 30. The supporting plate 10 has a supporting surface 11 for supporting an adhesive tape, and the fixing frame 20 is arranged on one side of the supporting surface 11 of the supporting plate 10. The pressing assembly 30 comprises a connecting piece, which is rotationally connected to the fixing frame 20 and abuts against the supporting surface 11 at one end of the connecting piece so as to press the adhesive tape on the supporting surface 11. The adhesive tape is conveyed to the supporting plate 10 by a conveying device and is placed on the supporting surface 11 in a substantially flat manner. Since the adhesive tape may not be uniformly tensioned during the conveying or the pasting process, wrinkles may be easily generated on the surface of the adhesive tape. In the application, the pressing assembly 30 is arranged, the connecting piece in the pressing assembly 30 is installed by the fixing frame 20, the connecting piece can rotate relative to the fixing piece, one end of the connecting piece abuts against the supporting surface 11, so that the adhesive tape can be flattened, the surface of the adhesive tape can be kept flat, the adhesive tape can be attached to the surface of a product in a flat state during the pasting process, and the pasting quality and the product yield are improved. When the connecting piece abuts against the supporting surface 11, the connecting piece can be pressed on the supporting surface 11 by the gravity of the connecting piece, or the abutting force can be increased by other structures (such as a spring) to improve the pressing effect of the connecting piece. The pressing device 100 has the advantages of simple structure and low cost since the pressing effect can be achieved without relying on a power source.

[0030] It can be understood that the connecting piece can flatten the adhesive tape on the supporting surface 11 when the connecting piece abuts against the supporting surface 11. In order to ensure that the adhesive tape can move on the supporting surface 11, the abutting force of the connecting piece on the adhesive tape should not be too large, so as to avoid that the adhesive tape is jammed during the conveying process. Therefore, it is necessary to ensure the smoothness of the movement of the adhesive tape. The specific value of the abutting force of the connecting piece is not limited in the application and can be adjusted according to the specific conditions in actual application.

[0031] Exemplarily, the pressing device 100 provided by the application can be used for pasting an adhesive tape on a battery cell, so as to facilitate further assembly operation after the adhesive tape is pasted on the battery cell. Of course, the pressing device 100 can also be used for pasting an adhesive tape on other products, which is not limited herein.

[0032] In some embodiments, the pressing assembly 30 further comprises a roller, which is rotationally arranged at the first end 311 of the connecting piece, the part of the connecting piece other than the first end 311 is rotationally connected to the fixing frame 20, and the roller abuts against the supporting surface 11. By arranging the roller, the roller can rotate along the movement direction of the adhesive tape, so as to reduce the friction between the connecting piece and the adhesive tape, the adhesive tape can smoothly and smoothly pass through the space between the roller 32 and the supporting surface 11 during the conveying process, and the problems that the adhesive tape is jammed or scratched by the connecting piece are avoided.

[0033] Of course, as an alternative implementation, an arc-shaped contact surface can also be provided at the abutment of the connector and the supporting surface 11, which also helps to reduce the friction between the connector and the tape and improve the smoothness of the tape when it passes through.

[0034] In some embodiments, the connector includes a connecting plate 31, one side of which faces the supporting surface 11. The roller's axis of rotation is parallel to the supporting surface 11, and the roller's circumferential direction is perpendicular to the direction of belt movement. The projection of the roller along a direction perpendicular to the supporting surface 11 lies within the supporting surface 11. By framing the connector as a connecting plate 31, a larger coverage area can be achieved. Simultaneously, the roller's axis of rotation is also along the width direction of the connecting plate 31 (e.g., ...). Figure 1 The roller is extended in the x-direction to increase the contact area between the roller and the tape, thereby improving the stability and effect of the adhesive application. The support surface 11 can be set in a roughly horizontal direction. One end of the support plate 10 (the adhesive application end) is used to contact the workpiece (the product to be adhesiveped) to achieve adhesive application. At this time, the projection of the roller in the vertical direction is located within the support surface 11. This avoids the roller extending beyond the support surface 11, that is, it avoids the roller protruding from the adhesive application end, thus preventing interference or collision between the roller and the workpiece and improving the reliability of the adhesive application operation.

[0035] Optionally, the roller can be positioned close to the adhesive end, allowing it to be closer to the workpiece, which helps improve the adhesive application effect and makes the tape adhere more smoothly to the workpiece surface.

[0036] As an alternative implementation, in addition to adopting the structure of the connecting plate 31, the connector can also adopt a rod-shaped structure, with a roller at one end of the rod and the other end of the rod connected to the fixing member.

[0037] by Figure 1 For example, the support plate 10 can be set horizontally, and the tape passes horizontally across the support surface 11. The fixing bracket 20 can be set above the support surface 11, or it can be set to the left or right side of the support plate, i.e. Figure 1 The connecting plate 31 is positioned on one side along the x-direction. When the connecting member adopts the form of a connecting plate 31, if the support plate 10 is horizontally positioned, the connecting plate 31 is also positioned approximately horizontally, with one surface (e.g., the bottom surface) of the connecting plate 31 facing the support surface 11. In this way, the connecting plate 31 and the support surface 11 can correspond to each other in the vertical direction (e.g., the z-direction), and the connecting plate 31 is pressed down in the vertical direction to abut against the support surface 11. Of course, in other examples, the support plate 10 can also be positioned vertically. In this case, the connecting plate 31 is also positioned vertically, with one side (e.g., the left or right side) of the connecting plate 31 facing the support surface 11 and able to abut against the support surface 11. It can be seen that the setting method and orientation of the support plate 10 can have various implementation methods, and this application does not specifically limit them.

[0038] In some embodiments, the pressing device 100 further includes a reset member 33, one end of which is connected to the fixing frame 20 and the other end to the connecting plate 31. The reset member 33 is used to provide a reset force on the roller abutting against the receiving surface. Utilizing the reset force of the reset member 33, a continuous force can be provided on the roller abutting against the supporting surface 11, increasing the interaction force between the roller and the receiving surface, allowing the roller to press better against the tape surface and improving the pressing effect.

[0039] For example, the reset element 33 may be a spring, torsion spring, sheet metal, etc.

[0040] In some embodiments, the connector has a second end 312 disposed opposite to the first end 311, a reset member 33 is connected to the second end 312, a hinge point 313 is formed between the fixing plate and the connecting plate 31, the hinge point 313 is disposed between the first end 311 and the second end 312, the reset member 33 is a spring, and the reset member 33 is used to provide a first direction (e.g., ...) to the second end 312. Figure 1 The contraction force (in the positive direction of the z-axis) of the roller abutting the support surface 11 has a force in the opposite direction to the first direction. By setting the hinge point 313 between the first end 311 and the second end 312, the connecting plate 31 can form a lever structure, with the hinge point 313 serving as the fulcrum of the lever structure. The roller and the reset member 33 are located on both sides of the hinge point 313, which can make full use of the space on the connecting plate 31, avoid mutual interference between the reset member 33 and the roller, and also help to reduce the space occupied by the entire pressing device 100, making the pressing device 100 structure more compact. The force provided by the reset member 33 is in the opposite direction to the force provided by the roller. Taking the support plate 10 as horizontal as an example, the roller provides downward pressure on the tape (such as the positive direction of the z-axis). Figure 2 As shown by the downward dashed arrow in the image, the reset element 33 provides an upward force (such as...). Figure 2 (As shown by the upward dashed arrow in the image). Taking the reset element 33 as an example, the spring is in a stretched state. Therefore, the spring is used to provide the contraction force to ensure that the roller can maintain contact with the support surface 11.

[0041] In some embodiments, the distance from the hinge point 313 to the reset member 33 is less than the distance from the hinge point to the roller's axis of rotation. This helps to increase the length of the roller extending beyond the hinge point 313 and shorten the extension distance of the reset member 33, making the entire lever structure easier to implement. On the other hand, the gravity of the connecting plate 31 at the section from the roller to the hinge point 313 also helps to better press the roller onto the tape surface.

[0042] Of course, in another embodiment, the roller and the reset member 33 can be arranged on the same side of the hinge point 313, that is, the hinge point 313 is arranged at the second end 312, and the reset member 33 is arranged between the hinge point 313 and the roller 32. At this time, the reset member 33 provides an action force in the same direction as the action force provided by the roller, that is, the reset member 33 can be a spring in a compressed state, which is used to provide an action force to extend to press the connecting plate 31 downward, so that the roller can be kept in abutment with the supporting surface 11.

[0043] In order to better keep the adhesive tape on the supporting surface 11, in some embodiments, the supporting surface 11 is further provided with suction holes 12 for vacuum suction of the adhesive tape. By using the action of vacuum suction, the adhesive tape can be fixed on the supporting surface 11, avoiding problems such as deviation and curling of the adhesive tape during the process of pasting the adhesive tape, which helps to improve the fixing effect of the adhesive tape and thus improves the pasting effect.

[0044] In some embodiments, the supporting plate 10 is further provided with a cutting hole 13 arranged on the end surface of the supporting plate 10 for contacting the workpiece, and the cutting hole 13 is used for the cutting knife 204 to pass through to cut the adhesive tape. The cutting hole 13 can be used for the cutting knife 204 to extend into or exit, and after the pasting of the adhesive tape is completed, the cutting knife 204 passes through the cutting hole 13 to contact and cut the adhesive tape, and after cutting, the cutting knife 204 exits from the cutting hole 13 to avoid affecting the pasting of the next workpiece.

[0045] In some embodiments, the fixing frame 20 includes a first fixing part 21 and a second fixing part connected to each other, the first fixing part 21 is used for connecting to the rack 201, and the second fixing part includes two connecting arms 22 facing the supporting surface 11, and the two sides of the connecting member are rotatably connected with the two connecting arms 22, respectively. By arranging the first fixing part 21, the pressing adhesive device 100 can be mounted to the rack 201 of the adhesive tape pasting equipment 200, and the connecting arm 22 can be connected with the connecting member (the connecting plate 31), so as to realize the rotary mounting of the connecting plate 31.

[0046] In the second aspect, referring to Figure 4 , the application further provides an adhesive tape pasting equipment 200 including a rack 201 and the pressing adhesive device 100 provided in the first aspect, and the fixing plate of the pressing adhesive device 100 is connected to the rack 201, and the rack 201 is used for conveying the adhesive tape to the pressing adhesive device 100. Optionally, the adhesive tape can be mounted on the rack 201 in the form of a roll 203, and a driving structure can be arranged on the rack 201 to drive the roll 203 to unwind, so as to realize the conveying of the adhesive tape to the pressing adhesive device 100. A plurality of tensioning rollers 202 can also be arranged on the rack 201, and the adhesive tape can be wound around the tensioning rollers 202, so that the adhesive tape can maintain a certain tension during the conveying process, thereby improving the flatness of the adhesive tape.

[0047] An example of the adhesive application device 200 is as follows: the adhesive tape is installed on the frame 201 in the form of a roll 203, and a driving structure is arranged on the frame 201 to drive the roll 203 to unwind, so as to realize the conveying of the adhesive tape to the adhesive pressing device 100. The adhesive tape is wound on the tensioning roller 202, so that the adhesive tape can maintain a certain tension during the conveying. The adhesive tape enters the supporting plate 10 of the adhesive pressing device 100, and the adhesive tape is pressed between the supporting surface 11 and the roller 32. The adhesive tape is exposed at the end (the adhesive application end) of the supporting plate 10, and the part of the supporting plate 10 can be in contact with the workpiece to transfer the adhesive tape to the surface of the workpiece to realize the adhesive application. During the transferring of the adhesive tape to the surface of the workpiece, the relative movement between the adhesive application device and the workpiece is controlled (the adhesive application device is moved or the workpiece is moved), and the adhesive tape is pulled to the direction of the workpiece by the adhesive force between the adhesive tape and the workpiece, so as to realize the adhesive application. After the adhesive application is completed, the cutter 204 is controlled to extend to cut the adhesive tape, the adhesive tape is maintained on the supporting surface 11 due to the vacuum effect of the suction hole 12, the workpiece with the applied adhesive is transferred away, and another workpiece to be applied with the adhesive is continuously inputted, and the above adhesive application action is repeated. The above is repeated to realize the continuous adhesive application.

[0048] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
