Description

Technical Field

[0001] The present application relates to the technical field of battery module processing, and particularly to a battery module film pasting device. Background Art

[0002] New energy vehicles use battery modules as the power source, and drive an electric motor through electric energy to provide power. With the development of technology, battery modules are evolving towards higher energy density and faster charging speed to meet users' demands for longer driving range and shorter charging time of new energy vehicles. A battery module usually consists of multiple battery cells, and these cells are connected through a precise electronic control unit (ECU) to ensure effective management and distribution of energy.

[0003] In new energy vehicles, the battery module not only bears the function of storing electric energy, but also is related to the overall performance and endurance of the vehicle. Due to the chemical properties of the battery cells themselves, when the temperature drops, the electrolyte in the battery cells becomes viscous, the migration rate of lithium ions slows down, resulting in a decrease in the activity of the electrolyte, and both the charge-discharge power and available energy of the battery cells decrease.

[0004] To reduce the influence of the chemical properties of the battery cells on the output performance of the battery module, a film block capable of heating the battery module can be pasted on the outer surface of the battery module. After the electric energy of the battery module is output to the film block, the film block can transfer a certain amount of heat to the surface of the battery module, so that the temperature inside the battery module will not be too low. However, in traditional technology, the film block is generally manually pasted on the outer surface of the battery module, and there are likely to be large errors in the pasting position of the film block, resulting in a part of the film block not being pasted on the outer surface of the battery module. The heat generated by this part of the film block is not transferred to the battery module, causing waste of the output electric energy of the battery module and affecting the endurance performance of new energy vehicles. Summary of the Utility Model

[0005] Based on this, the present utility model provides a battery module film pasting device that can solve or at least alleviate the above technical problems.

[0006] The present utility model provides a battery module film pasting device, including:

[0007] A bracket provided with a first chute;

[0008] A lifting assembly connected to the bracket; one end of the lifting assembly is slidably arranged relative to the bracket along the first chute;

[0009] A clamping jaw connected to the other end of the lifting assembly; the clamping jaw is used for clamping a heating film; and

[0010] The first positioning indicator is provided with a plurality of first positioning marks; the first positioning indicator is arranged on one side of the first sliding groove; the first positioning marks are used for the alignment of the lifting assembly; the plurality of first positioning marks are linearly distributed parallel to the first sliding groove.

[0011] Beneficial effects: The first sliding groove guides one end of the lifting assembly. Since the clamping jaw is connected to the lifting assembly, the moving direction of the clamping jaw is parallel to the first sliding groove. The lifting assembly is connected to one end of the clamping jaw, so that the lifting assembly can drive the clamping jaw to move up and down relative to the bracket. When the clamping jaw is in the open state and descends to the first station where the heating film is suspended, the clamping jaw can clamp the heating film by contracting. Then, under the limitation of the first sliding groove, the clamping jaw moves towards the second station where the battery module is placed. According to the first positioning marks on the first positioning indicator, the position where the lifting assembly needs to finally stop can be determined. When the lifting assembly reaches the stop position, the heating film just moves to the horizontal side of the side of the battery module along with the clamping jaw. At this time, as long as the heating film is pressed against the side of the battery module by hand or other devices, the heating film can be accurately pressed and attached to the side of the battery module. Subsequently, the clamping jaw switches to the open state, and the lifting assembly drives the clamping jaw to rise, so that the clamping jaw leaves the heating film. When the placement position of the battery module in the second station remains the same each time, as long as the lifting assembly is moved to stop corresponding to the specified first positioning mark each time, the heating film clamped by the clamping jaw can be accurately corresponding to the surface of the battery module in the height direction and the horizontal direction, improving the alignment accuracy between the heating film and the side of the battery module, which is beneficial to preventing a part of the heating film from not being pasted on the outer surface of the battery module and avoiding the waste of the electric energy output from the battery module to the heating film.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0030] Reference to "embodiment" or "implementation manner" in this article means that a specific feature, structure, or characteristic described in connection with the embodiment or implementation manner may be included in at least one embodiment of the present application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0031] Next, the technical solutions provided by the embodiments of the present application will be introduced in conjunction with the accompanying drawings.

[0032] Combined with Figure 1 As shown, the present application provides a battery module film laminating device 100.

[0033] In some embodiments, the battery module film laminating device 100 is used to assist in laminating the heating film 902 to the side surface 903 of the battery module 901. Specifically, at an angle facing the side surface 903 of the battery module 901, the battery module film laminating device 100 is used to make the heating film 902 more stably and accurately correspond to the side surface 903 of the battery module 901 in the height direction and the horizontal direction.

[0034] In some embodiments, as shown in combination Figure 1 the battery module film laminating device 100 includes: a bracket 20, a lifting assembly 30, a clamping jaw 40, and a first positioning indicator 50. The bracket 20 is provided with a first sliding groove 21. The lifting assembly 30 is connected to the bracket 20. One end of the lifting assembly 30 is slidably arranged relative to the bracket 20 along the first sliding groove 21. The clamping jaw 40 is connected to the other end of the lifting assembly 30, and the clamping jaw 40 is used to clamp the heating film 902. The first positioning indicator 50 is provided with a plurality of first positioning marks. The first positioning indicator 50 is arranged on one side of the first sliding groove 21. The first positioning marks are used for the lifting assembly 30 to align. The plurality of first positioning marks are linearly distributed parallel to the first sliding groove 21.

[0035] Specifically, the first chute 21 guides one end of the lifting assembly 30. Since the clamping jaws 40 are connected to the lifting assembly 30, the moving direction of the clamping jaws 40 is parallel to the first chute 21. The lifting assembly 30 is connected to one end of the clamping jaws 40, so that the lifting assembly 30 can drive the clamping jaws 40 to move up and down relative to the bracket 20. When the clamping jaws 40 are in the open state and descend to the first station where the heating film 902 is suspended, the clamping jaws 40 can clamp the heating film 902 by contracting. Then, under the limitation of the first chute 21, the clamping jaws 40 move towards the second station where the battery module 901 is placed. According to the first positioning mark on the first positioning indicator 50, the position where the lifting assembly 30 needs to finally stop can be determined. When the lifting assembly 30 reaches the stop position, the heating film 902 just moves to the horizontal side of the side surface 903 of the battery module 901 along with the clamping jaws 40. At this time, as long as the heating film 902 is pressed towards the side surface 903 of the battery module 901 by hand or other devices, the heating film 902 can be accurately pressed and adhered to the side surface 903 of the battery module 901. Thereafter, the clamping jaws 40 switch to the open state, and the lifting assembly 30 drives the clamping jaws 40 to rise, so that the clamping jaws 40 leave the heating film 902. When the placement position of the battery module 901 in the second station remains the same each time, as long as the lifting assembly 30 is moved to stop corresponding to the specified first positioning mark each time, the heating film 902 clamped by the clamping jaws 40 can be accurately corresponding to the surface of the battery module 901 in the height direction and the horizontal direction, improving the alignment accuracy between the heating film 902 and the side surface 903 of the battery module 901, which is beneficial to preventing a part of the heating film 902 from not being pasted to the outer surface of the battery module 901 and avoiding waste of the electric energy output from the battery module 901 to the heating film 902.

[0036] Specifically, the relative direction between the first station and the second station is parallel to the extension direction of the first chute 21. The extension direction of the first chute 21 is also perpendicular to the surface of the battery module 901. Specifically, the first positioning mark corresponds to the position of the second station, so as to indicate the operator to stop the lifting assembly 30 at a position close to the battery module 901. In some embodiments, during the process of the heating film 902 being driven by the clamping jaws 40 to move from the first station to the second station, restricted by the direction of the first chute 21, the height and horizontal position of the heating film 902 will not change. Therefore, as long as the heating film 902 can be in an accurately corresponding position to the side surface 903 of the battery module 901 at the first station, during the process of the heating film 902 moving close to the side surface 903 of the battery module 901, it can be avoided that the heating film 902 cannot be accurately adhered to the side surface 903 of the battery module 901 due to the position deviation of the heating film 902.

[0037] In some embodiments, when the jaw 40 grips the heating film 902 in the first station, the position of the lifting assembly 30 corresponds to another specified first positioning mark, so that the jaw 40 can accurately grip the heating film 902 in the first station.

[0038] In some embodiments, the first station is arranged within the moving range of the jaw 40. In some embodiments, the first station is arranged within the bracket 20. In some embodiments, when the heating film 902 is in the first station, the heating film 902 is arranged vertically, and two side edges of the heating film 902 are respectively clamped by two groups of clamping pieces. The jaw 40 is used to clamp the upper edge of the heating film 902. After the jaw 40 clamps the upper edge of the heating film 902, the two groups of clamping pieces are loosened and respectively leave the side edges of the heating film 902, so that the jaw 40 can drive the heating film 902 to move towards the side surface 903 of the battery module 901. In some embodiments, the number of jaws 40 can be set according to the length of the upper edge of the heating film 902. A plurality of jaws 40 are distributed along a direction parallel to the upper edge of the heating film 902. By simultaneously clamping the upper edge of the heating film 902 with a plurality of jaws 40, the flatness of the heating film 902 before being attached to the side surface 903 of the battery module 901 can be ensured.

[0039] In some embodiments, in combination with Figure 1 As shown, the bracket 20 includes a bottom plate 25 and a plurality of vertical rods 26 connected to the bottom plate 25. The vertical rods 26 are arranged on the upper side of the bottom plate 25. In some embodiments, the bottom plate 25 is provided with a positioning groove at a position corresponding to the second station. The positioning groove is used to accommodate the bottom of the battery module 901, so as to position the battery module 901 and enable the heating film 902 to accurately adhere to the side surface 903 of the battery module 901.

[0040] In some embodiments, in combination with Figure 1 and Figure 2 As shown, the bracket 20 includes a first rod 22 and a second rod 23. The first rod 22 and the second rod 23 are arranged at intervals in the horizontal direction. A first chute 21 is arranged between the first rod 22 and the second rod 23. A part of the lifting assembly 30 is located above the first rod 22 and the second rod 23, and the width of a part of the lifting assembly 30 is greater than the horizontal distance between the first rod 22 and the second rod 23, so that the lifting assembly 30 can be suspended on the bracket 20, and the lifting assembly 30 can move under the support of the first rod 22 and the second rod 23. A part of the lifting assembly 30 is located in the first chute 21, so that the lifting assembly 30 is limited by the first rod 22 and the second rod 23 during the moving process. In some embodiments, the first rod 22 and the second rod 23 are arranged in parallel, so that the first chute 21 has a consistent width.

[0041] In some embodiments, in combination withFigure 1 As shown, the bracket 20 further includes a cross bar 27, and the cross bar 27 is connected between the vertical bars 26. Specifically, the cross bar 27 is connected to the upper ends of the vertical bars 26. In some embodiments, one end of the first bar 22 is connected to one of the cross bars 27, and the other end is connected to another cross bar 27, and the two cross bars 27 are arranged opposite to each other. One end of the second bar 23 is connected to one of the cross bars 27, and the other end is connected to another cross bar 27, and the two cross bars 27 are arranged opposite to each other.

[0042] In some other embodiments, the bracket 20 includes a top plate, and the first chute 21 is arranged on the top plate. In some embodiments, the top plate is connected between the vertical bars 26. Specifically, the top plate is connected to the upper ends of the vertical bars 26.

[0043] In some other embodiments, the bracket 20 can also form the first chute 21 through other structures, and can also support the lifting assembly 30 through other structures.

[0044] In some embodiments, in combination Figure 1 with Figure 2 As shown, the lifting assembly 30 includes a first sliding member 31, a first bolt column 32 connected to the upper end of the first sliding member 31, and a first nut member 33 connected to the first bolt column 32. The first sliding member 31 is arranged on the lower side of the first chute 21. The first bolt column 32 is inserted into the first chute 21. The first nut member 33 is arranged on the upper side of the first chute 21. The outer diameters of the upper end of the first sliding member 31 and the first nut member 33 are respectively greater than the width of the first chute 21. One of the first sliding member 31 and the first nut member 33 is fixedly connected to the first bolt column 32, and the other is threadedly connected to the first bolt column 32, so as to be able to adjust the distance between the upper end of the first sliding member 31 and the first nut member 33. When the distance between the upper end of the first sliding member 31 and the first nut member 33 is small, the first nut member 33 abuts against the wall surface of the bracket 20 around the upper side of the first chute 21, and the upper end of the first sliding member 31 abuts against the wall surface of the bracket 20 around the lower side of the first chute 21. A large frictional force is generated between the first sliding member 31 and the bracket 20, so as to be able to prevent the lifting assembly 30 from continuing to move along the first chute 21. Therefore, when the lifting assembly 30 reaches the stop position, but the heating film 902 is not attached to the side surface 903 of the battery module 901, by locking the position of the lifting assembly 30, during the process of pressing the heating film 902 against the side surface 903 of the battery module 901, it is possible to avoid the lifting assembly 30 driving the heating film 902 to shift, ensuring the accuracy of the attachment of the heating film 902.

[0045] In some embodiments, in combination Figure 2As shown, the first sliding member 31 is fixedly connected to the first bolt column 32, and the first nut member 33 is threadedly sleeved outside the first bolt column 32. In some other embodiments, it may also be that the first nut member 33 is fixedly connected to the first bolt column 32, and the first bolt column 32 is threadedly inserted into the first sliding member 31.

[0046] In some embodiments, when the distance between the upper end of the first sliding member 31 and the first nut member 33 is small, the upper end of the first sliding member 31 abuts against the lower sides of the first rod 22 and the second rod 23 respectively. The first nut member 33 abuts against the upper sides of the first rod 22 and the second rod 23 respectively.

[0047] In some embodiments, in combination with Figure 2 As shown, the lifting assembly 30 includes a first sliding member 31 slidably connected to the bracket 20, a telescopic rod 34 nested and cooperating with the first sliding member 31, and a telescopic driving member 35 connected to the telescopic rod 34. The telescopic driving member 35 is used to drive the telescopic rod 34 to telescopically move relative to the first sliding member 31. The jaw 40 is connected to the telescopic rod 34. By driving the telescopic rod 34 to telescopically move relative to the first sliding member 31 by the telescopic driving member 35, the lifting of the jaw 40 relative to the bracket 20 can be realized. In some embodiments, the lifting assembly 30 further includes a first internal screw 36 rotatably disposed within the first sliding member 31. One end of the first internal screw 36 is coupled to the telescopic driving member 35. The first internal screw 36 is threadedly inserted into the telescopic rod 34. The circumferential angle of the telescopic rod 34 relative to the first sliding member 31 is limited. Therefore, when the telescopic driving member 35 drives the first internal screw 36 to rotate through the first transmission member 37, the first internal screw 36 causes the telescopic rod 34 to move axially through screw transmission. Specifically, the telescopic driving member 35 is a motor. The first transmission member 37 between the telescopic driving member 35 and the first internal screw 36 may be a plurality of gears. More specifically, the plurality of gears may be meshed in sequence in a decelerating transmission form. In some embodiments, the lifting assembly 30 is an electric push rod, a telescopic cylinder, or other devices capable of driving the jaw 40 to lift and move.

[0048] In some embodiments, in combination with Figure 1 and Figure 2 As shown, the jaw 40 is connected to the lower end of the telescopic rod 34. In some embodiments, in combination with Figure 1 As shown, the battery module film laminating device 100 further includes a first control button 38 for controlling the operation of the telescopic driving member 35. Therefore, the first control button 38 can be used to control the upward or downward movement of the jaw 40, so that the jaw 40 can descend to the position of the upper edge of the heating film 902, or the jaw 40 can rise to leave the upper edge of the heating film 902.

[0049] In some embodiments, in combination withFigure 2 As shown, the lifting assembly 30 is also partially received in the first chute 21, and this part fits against the edge of the first chute 21, so as to prevent the lifting assembly 30 from rotating during the process of moving along the first chute 21. In some embodiments, the upper end of the first slider 31 is partially received in the first chute 21.

[0050] In some embodiments, in combination Figure 3 As shown, the clamping jaw 40 includes a first jaw body 41 connected to the lifting assembly 30, a second jaw body 42 movably connected to the first jaw body 41, and a grasping driving member 43 connected to the first jaw body 41. The grasping driving member 43 is used to drive the second jaw body 42 to move relative to the first jaw body 41. Specifically, driven by the grasping driving member 43, one end of the second jaw body 42 moves closer to one end of the first jaw body 41, so as to clamp the upper edge of the heating film 902 between the first jaw body 41 and the second jaw body 42. In some embodiments, a slider 44 is slidably connected to the second jaw body 42. The clamping jaw 40 further includes a transmission rod 45. The transmission rod 45 is rotatably connected to the first jaw body 41. The transmission rod 45 is threadedly connected to the slider 44. The grasping driving member 43 is connected to the transmission rod 45. Specifically, when the transmission rod 45 rotates and changes the position of the slider 44 on the transmission rod 45, the slider 44 can drive the second jaw body 42 to move relative to the first jaw body 41. Thus, the clamping jaw 40 can be opened and closed. In some embodiments, the second jaw body 42 is rotatably connected to the first jaw body 41.

[0051] In some embodiments, in combination Figure 3 As shown, the second jaw body 42 is provided with a third chute 421. The slider 44 is slidably disposed in the third chute 421. The main body of the slider 44 is cylindrical and is slidably received in the third chute 421. The transmission rod 45 is threadedly inserted through the main body of the slider 44. The width of the main body of the slider 44 is less than or equal to the width of the third chute 421. Both ends of the slider 44 are outside the third chute 421, and the width of the end of the slider 44 is greater than the width of the third chute 421.

[0052] In some other embodiments, the clamping jaw 40 can also be other structures capable of clamping the heating film 902.

[0053] In some embodiments, in combination Figure 1 As shown, the battery module film pasting device 100 further includes a second control button 46, and the second control button 46 is used to control the operation of the grasping driving member 43. Therefore, the second control button 46 can be used to control the opening and closing of the clamping jaw 40.

[0054] In some embodiments, the first positioning indicator 50 is a scale. The first positioning mark is a scale line. Specifically, the length of the first positioning indicator 50 corresponds to the length of the first sliding groove 21. In one embodiment, the length of the first positioning indicator 50 is greater than or equal to the length of the first sliding groove 21. In some other embodiments, the length of the first sliding groove 21 may also be set according to the movement range of the clamping jaw 40. In some embodiments, the first positioning indicator 50 is mounted on the first rod 22.

[0055] In some other embodiments, the first positioning indicator 50 may also be an electronic display element capable of displaying the first positioning mark. In some embodiments, the first positioning indicator 50 includes, but is not limited to, a strip-shaped liquid crystal screen or ink screen.

[0056] In some embodiments, in combination Figure 1 with Figure 4 as shown, the bracket 20 is provided with a second sliding groove 24. A part of the translation assembly 60 is slidably received in the second sliding groove 24. The battery module laminating device 100 further includes a second positioning indicator 80, and the second positioning indicator 80 is provided with a plurality of second positioning marks. The second positioning indicator 80 is disposed on one side of the second sliding groove 24. The second positioning marks are used for aligning the translation assembly 60. The plurality of second positioning marks are linearly distributed parallel to the second sliding groove 24. Specifically, according to the second positioning marks on the second positioning indicator 80, the position where the translation assembly 60 needs to finally stop can be determined. When the translation assembly 60 reaches the stop position, the pressing plate 70 just moves to one side of the battery module 901, and the distance between the plane where the pressing plate 70 is located and the plane of the side surface 903 of the battery module 901 is relatively small. In some embodiments, after the translation assembly 60 horizontally ejects the pressing plate 70, the pressing plate 70 can move in a direction parallel to the side surface 903 of the battery module 901 and contact the surface of the heating film 902. Further, by driving the pressing plate 70 to move back and forth through the translation assembly 60, the pressing plate 70 can smooth the surface of the heating film 902 back and forth. In some embodiments, the second positioning indicator 80 is mounted on the third rod 28.

[0057] In some embodiments, the second positioning indicator 80 is a scale. The second positioning mark is a scale line. In some other embodiments, the second positioning indicator 80 may also be an electronic display element capable of displaying the second positioning mark. In some embodiments, the second positioning indicator 80 includes, but is not limited to, a strip-shaped liquid crystal screen or ink screen.

[0058] In some embodiments, in combination Figure 1 with Figure 4As shown, the battery module film laminating device 100 further includes a translation assembly 60 and a pressing plate 70 connected to the translation assembly 60. One end of the translation assembly 60 is slidably connected to the bracket 20 along a direction parallel to the first chute 21. The other end of the translation assembly 60 is used to drive the pressing plate 70 to move along a direction parallel to the side surface 903 of the battery module 901. Specifically, when the heating film 902 is attached to the side surface 903 of the battery module 901, the translation assembly 60 moves along a direction parallel to the first chute 21 and approaches the heating film 902. Thereafter, the translation assembly 60 ejects the pressing plate 70 towards the side surface 903 of the battery module 901. One side surface of the pressing plate 70 contacts the surface of the heating film 902 facing away from the battery module 901, thereby smoothing the wrinkles on the heating film 902, enabling the heating film 902 to fit more smoothly to the side surface 903 of the battery module 901, and enabling the heat generated by the heating film 902 to be transferred to the battery module 901 more effectively.

[0059] In some embodiments, when the translation assembly 60 ejects the pressing plate 70, the pressing plate 70 may be between the first working position and the second working position. In some other embodiments, when the translation assembly 60 retracts the pressing plate 70, the pressing plate 70 leaves the relative space range between the first working position and the second working position. Therefore, the pressing plate 70 does not affect the movement of the heating film 902 from the first working position to the side surface 903 of the battery module 901 at this time.

[0060] In some embodiments, in combination with Figure 1 and Figure 4 As shown, the translation assembly 60 includes a second sliding member 61, a second bolt column 62 connected to one end of the second sliding member 61, and a second nut member 63 connected to the second bolt column 62. The second sliding member 61 is disposed on one side of the second chute 24. The second bolt column 62 is inserted into the second chute 24. The second nut member 63 is disposed on the other side of the second chute 24. The outer diameters of the second sliding member 61 and the second nut member 63 are respectively greater than the width of the second chute 24. One of the second sliding member 61 and the second nut member 63 is fixedly connected to the second bolt column 62, and the other is threadedly connected to the second bolt column 62, so as to adjust the distance between one end of the second sliding member 61 and the second nut member 63. When the distance between one end of the second sliding member 61 and the second nut member 63 is small, one end of the second sliding member 61 abuts against the wall surface of the bracket 20 around the second chute 24 on one side, and the second nut member 63 abuts against the wall surface of the bracket 20 around the second chute 24 on the other side. A relatively large frictional force is generated between the second sliding member 61 and the bracket 20, thereby preventing the translation assembly 60 from continuing to move along the second chute 24. Therefore, when the translation assembly 60 reaches the stop position, by locking the position of the translation assembly 60, it is possible to prevent the pressing plate 70 from moving when smoothing the heating film 902, enabling the pressing plate 70 to apply sufficient pressure to the heating film 902 to ensure that the heating film 902 can fit smoothly to the side surface 903 of the battery module 901.

[0061] In some embodiments, in combination with Figure 4 As shown, the second sliding member 61 is fixedly connected to the second bolt post 62, and the second nut member 63 is threadedly sleeved outside the second bolt post 62. In some other embodiments, it may also be that the second nut member 63 is fixedly connected to the second bolt post 62, and the second bolt post 62 is threadedly inserted into the second sliding member 61.

[0062] In some embodiments, in combination with Figure 1 and Figure 4 As shown, the bracket 20 includes a third rod 28 and a fourth rod 29. The third rod 28 and the fourth rod 29 are parallel and spaced apart. The second chute 24 is provided between the third rod 28 and the fourth rod 29. When the distance between the upper end of the second sliding member 61 and the second nut member 63 is small, the upper end of the second sliding member 61 abuts against the horizontal sides of the third rod 28 and the fourth rod 29 respectively. The second nut member 63 abuts against the other horizontal sides of the third rod 28 and the fourth rod 29 respectively.

[0063] In some embodiments, in combination with Figure 4 As shown, the translation assembly 60 includes a second sliding member 61 slidably connected to the bracket 20, a translation rod 64 nested with the second sliding member 61, and a translation driving member 65 connected to the translation rod 64. The translation driving member 65 is used to drive the translation rod 64 to telescopically move relative to the second sliding member 61. The pressing plate 70 is connected to the translation rod 64. By driving the telescopic movement of the translation rod 64 relative to the second sliding member 61 by the translation driving member 65, the horizontal movement of the pressing plate 70 relative to the bracket 20 can be realized. In some embodiments, the translation assembly 60 further includes a second internal screw 66, and the second internal screw 66 is rotatably disposed inside the second sliding member 61. One end of the second internal screw 66 is coupled to the translation driving member 65. The second internal screw 66 is threadedly inserted into the translation rod 64. The circumferential angle of the translation rod 64 relative to the second sliding member 61 is limited. Therefore, when the translation driving member 65 drives the second internal screw 66 to rotate through the second transmission member 67, the second internal screw 66 makes the translation rod 64 move axially through thread transmission. Specifically, the translation driving member 65 is a motor. The second transmission member 67 between the translation driving member 65 and the second internal screw 66 may be several gears. In some embodiments, the translation assembly 60 is an electric push rod, a telescopic cylinder or other devices capable of driving the pressing plate 70 to move horizontally.

[0064] In some embodiments, in combination with Figure 1As shown, the pressing plate 70 is connected to one end of the translation rod 64 close to the second station. In some embodiments, the battery module film laminating device 100 further includes a third control button 68 for controlling the operation of the translation driving member 65. Therefore, the third control button 68 can be used to control the telescopic movement of the pressing plate 70, so that the pressing plate 70 can press against each surface of the heating film 902, enabling each part of the heating film 902 to be flatly attached to the side surface 903 of the battery module 901.

[0065] In some embodiments, in combination with Figure 5 As shown, the pressing plate 70 has an arc-shaped end face 71. The pressing plate 70 contacts the heating film 902 through this end face 71, thereby avoiding directly abutting against the edge of the heating film 902 and preventing the edge of the heating film 902 from detaching from the side surface 903 of the battery module 901. Further, when the end face 71 of the pressing plate 70 contacts the side surface 903 of the battery module 901, the pressing plate 70 undergoes a certain deformation and generates a certain pressure on the heating film 902, and this pressure can make the heating film 902 more flatly attached to the side surface 903 of the battery module 901. In some embodiments, the pressing plate 70 forms an arc-shaped end face 71 through local deformation.

[0066] The above embodiments are only descriptions of the preferred embodiments of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present application should all fall within the protection scope determined by the claims of the present application.
