It should also be understood that terms defined in a general dictionary, such as those, should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0032] Technologies, methods and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification.

[0033] Such asFigures 1 to 5 As shown in the figure, the electrode pasting device disclosed in the present application includes a mounting seat assembly 10 and a negative pressure adsorption assembly 20. There are two negative pressure adsorption assemblies 20, and the two negative pressure adsorption assemblies 20 are respectively arranged corresponding to the upper and lower surfaces of the electrode to be pasted. The negative pressure adsorption assembly 20 includes a first vertical driving structure 21 and a negative pressure structure 22. The first vertical driving structure 21 is connected to the mounting seat assembly 10, and the negative pressure structure 22 is connected to the first vertical driving structure 21.

[0034] Applying the technical solution of the embodiment of the present application, the fixture clamps the side of the electrode to be pasted and moves it between the two negative pressure adsorption assemblies 20. The two first vertical driving structures 21 move towards each other. The two negative pressure structures 22 adsorb the film and move towards each other under the action of the first vertical driving structure 21, approach the electrode, and simultaneously press the two films on the upper and lower surfaces of the electrode respectively to complete the pasting. The technical solution of this embodiment effectively solves the problem of low processing efficiency in the prior art during the electrode pasting process.

[0035] As Figures 1 to 5 shown, in the technical solution of this embodiment, the negative pressure structure 22 includes a negative pressure part 221 and a support seat 222. The support seat 222 is connected to the first vertical driving structure 21. The support seat 222 has a first side plate, and the height of the upper edge of the first side plate in the vertical direction is higher than the height of the negative pressure part 221 in the vertical direction. The negative pressure part 221 is connected to the support seat 222 and is arranged in a fitting manner with the first side plate. The support seat 222 is L-shaped. The negative pressure part 221 is fixed on the first bottom plate of the support seat 222 and is arranged in a fitting manner with the first side plate. The first side plate plays a role in positioning the film strip on the negative pressure part 221 to prevent the film strip from moving out of the range of the negative pressure part 221 during the movement process. The negative pressure part 221 has a plurality of negative pressure adsorption holes, and the plurality of negative pressure adsorption holes provide negative pressure to adsorb the film strip on the surface of the negative pressure part 221. The first vertical driving structure 21 drives the support seat 222 to approach or move away from the electrode plate, and the film strip adsorbed on the surface of the negative pressure part 221 approaches or moves away from the electrode plate. The two negative pressure parts 221 drive the two film strips to approach the electrode plate simultaneously and press the two films on the upper and lower surfaces of the electrode plate at the same time to complete the electrode pasting. The film is fixed by means of negative pressure adsorption. While ensuring stable fixation, the flatness of the film is guaranteed, and then simultaneous pasting is completed, with high pasting efficiency.

[0036] As Figures 1 to 5 shown, in the technical solution of this embodiment, the electrode pasting device further includes a fixing component 30. The fixing component 30 is connected to the mounting seat assembly 10, and the fixing component 30 is arranged corresponding to the negative pressure adsorption assembly 20 one by one. The fixing component 30 fixes the film strip on the negative pressure adsorption assembly 20 to further prevent the film strip from shifting in position.

[0037] AsFigures 1 to 5 As shown, in the technical solution of this embodiment, the fixing component 30 includes a second vertical driving structure 31 and a fixing structure 32. The first end of the fixing structure 32 is rotatably connected to the output end of the second vertical driving structure 31. The fixing structure 32 is rotatably connected to the mounting seat assembly 10. The second end of the fixing structure 32 is correspondingly arranged with the negative pressure adsorption component 20. The second vertical driving structure 31 drives the first end of the fixing structure 32 to move in the vertical direction. The fixing structure 32 rotates around the connection between it and the mounting seat assembly 10. The movement direction of the second end of the fixing structure 32 is opposite to that of the first end of the fixing structure 32. When the first end of the fixing structure 32 rises under the action of the second vertical driving structure 31, the second end of the fixing structure 32 descends and moves towards the negative pressure structure 22. The second end of the fixing structure 32 and the negative pressure part 221 jointly act to press the film strip against the surface of the negative pressure part 221, further ensuring the flatness of the film during the film pasting process. There are a plurality of protrusions on the fixing structure 32. During the fixing process, the plurality of protrusions press on the surface of the film strip. The setting of the protrusions reduces the contact area between the fixing structure 32 and the film strip, avoiding the difficulty of separating the film strip from the fixing structure 32 due to excessive viscosity.

[0038] As Figures 1 to 5 shown, in the technical solution of this embodiment, the electrode film pasting device further includes a traction component 40. The traction component 40 is connected to the mounting seat assembly 10, and the traction component 40 is correspondingly arranged with the negative pressure adsorption component 20 one by one. The traction component 40 is used to continuously traction the film strip to the negative pressure adsorption component 20, and then the negative pressure adsorption component 20 fixes the film strip to complete continuous electrode film pasting.

[0039] As Figures 1 to 5 shown, in the technical solution of this embodiment, the traction component 40 includes a first horizontal driving structure 41 and a clamping structure 42. The clamping structure 42 is connected to the first horizontal driving structure 41, and the clamping structure 42 is correspondingly arranged with the negative pressure structure 22. The clamping structure 42 clamps the film strip. The first horizontal driving structure 41 drives the clamping structure 42 to move towards the negative pressure adsorption component 20, so that part of the film strip extends into the negative pressure adsorption component 20. The negative pressure adsorption component 20 performs negative pressure adsorption on the film strip. The first horizontal driving structure 41 moves away from the negative pressure adsorption component 20 to complete the reset, and uses the clamping structure 42 to clamp the subsequent film strips, realizing continuous feeding of the film strips and improving the processing efficiency.

[0040] As Figures 1 to 5As shown, in the technical solution of this embodiment, the clamping structure 42 includes a first clamping portion 421, a second clamping portion 422, and a second horizontal driving portion 423. The first clamping portion 421 is connected to the first horizontal driving structure 41. The first clamping portion 421 includes a second bottom plate and a second side plate, and the second bottom plate is connected to the second side plate. The second clamping portion 422 is rotatably connected to the second side plate. The output end of the second horizontal driving portion 423 is correspondingly arranged with the first end of the second clamping portion 422. The film is arranged between the second side plate and the second end of the second clamping portion 422. The second horizontal driving portion 423 moves along the y-axis direction, pushing the second clamping portion 422 to rotate. The second clamping portion 422 and the second bottom plate jointly clamp the film strip. The first horizontal driving structure 41 moves along the y-axis direction, driving the first clamping portion 421 and the second clamping portion 422 to approach the negative pressure adsorption assembly 20 together, and placing the film strip on the negative pressure adsorption assembly 20. By adopting the method of driving the second clamping portion 422 to rotate by the second horizontal driving portion 423, the structure is simple, easy to implement, and easy to maintain.

[0041] As Figures 1 to 5 shown, in the technical solution of this embodiment, the clamping structure 42 further includes an elastic member. The first end of the elastic member is connected to the second side plate, and the second end of the elastic member is connected to the second clamping portion 422. When the second horizontal driving portion 423 drives the second clamping portion 422 to rotate, the elastic member is compressed. When the second horizontal driving portion 423 stops compressing, the second clamping portion 422 resets under the action of the elastic force of the elastic member, releasing the film strip. The setting of the elastic member realizes the automatic reset of the second clamping portion 422, reduces the control difficulty, and is convenient for operation.

[0042] As Figures 1 to 5 shown, in the technical solution of this embodiment, the traction assembly 40 further includes a first shaft body 43, a second shaft body 44, and a third shaft body 45. The first shaft body 43, the second shaft body 44, and the third shaft body 45 are all rotatably connected to the mounting seat assembly 10. The film reel is sleeved on the first shaft body 43. The film strip passes under the second shaft body 44 and above the third shaft body 45 and is threaded between the first clamping portion 421 and the second clamping portion 422. The film strip is tightly connected to the second shaft body 44 and the third shaft body 45. Pull out one end of the film strip, pass it under the second shaft body 44 and above the third shaft body 45, and then pass it between the first clamping portion 421 and the second clamping portion 422. The setting of the third shaft body 45 ensures the angle at which the film strip enters the clamping structure 42, avoiding excessive stress on the film strip during traction and resulting in fracture. The second shaft body 44 includes a first limiting section and a second limiting section, which are arranged at intervals. The film strip is located between the first limiting section and the second limiting section. The setting of the first limiting section and the second limiting section limits the film strip, avoiding the position of the film strip shifting during the conveying process, resulting in the film strip falling off and affecting the glue pasting work.

[0043] As Figures 1 to 5 shown, in the technical solution of this embodiment, the electrode pasting device further includes a cutting assembly 50. The cutting assembly 50 is connected to the mounting seat assembly 10. The cutting assembly 50 and the negative pressure adsorption assembly 20 are arranged in one-to-one correspondence. A part of the cutting assembly 50 is located between the traction assembly 40 and the negative pressure adsorption assembly 20. After the two negative pressure adsorption assemblies 20 press the two film strips on the upper and lower surfaces of the electrode, the cutting assembly 50 cuts the two films respectively to complete pasting. The setting of the cutting assembly 50 facilitates the separation of the film pasted on the electrode plate and the film not pasted on the electrode plate, facilitating the blanking of the electrode.

[0044] As Figures 1 to 5 shown, in the technical solution of this embodiment, the cutting assembly 50 includes a fifth horizontal driving structure 51 and a tool structure 52. The fifth horizontal driving structure 51 drives the tool structure 52 to move along the x-axis direction to realize the separation of the film strip. The tool structure 52 includes a plurality of cutter teeth. The plurality of cutter teeth are connected in sequence. The heights of the plurality of cutter teeth increase continuously from both ends to the middle, forming a serrated tool structure 52. Since the rubber strip itself has strong deformation ability, the serrated tool structure 52 can move repeatedly along the x-axis direction to realize the cutting of the rubber strip, and the cutting effect is good.

[0045] As Figures 1 to 5 shown, in the technical solution of this embodiment, the mounting seat assembly 10 includes a mounting seat 11, a third horizontal driving structure 12 and a fourth horizontal driving structure 13. The third horizontal driving structure 12 is arranged along the x-axis direction. The mounting seat 11 is fixed on the third horizontal driving structure 12. The fourth horizontal driving structure 13 is arranged along the y-axis direction. The third horizontal driving structure 12 is arranged on the fourth horizontal driving structure 13. Under the combined action of the third horizontal driving structure 12 and the fourth horizontal driving structure 13, the negative pressure adsorption assembly 20 is moved on the horizontal plane, facilitating the movement of the negative pressure adsorption assembly 20 to the battery to be pasted.

[0046] As described above, in this application: the longitudinal cylinder, the bottom plate, and the longitudinal linear guide form a longitudinal driving mechanism (the fourth horizontal driving structure 13). The longitudinal cylinder and the longitudinal linear guide are fixed on the bottom plate. The bottom plate is fixed on the frame (not shown in the figure). The transverse linear guide, the intermediate transition connecting plate, the support seat, and the transverse cylinder form a transverse driving mechanism (the third horizontal driving structure 12). The transverse linear guide and the transverse cylinder are fixed on the intermediate transition connecting plate. The intermediate transition connecting plate is fixed on the slider of the longitudinal linear guide. The lower lifting cylinder, the lower piece support seat, the lower support seat, the lower push block, the lower connecting rod, the lower pressing claw, the lower blade, the lower intermediate connecting seat, the lower cutting cylinder, the lower blade seat, the lower sheet feeding cylinder, the lower sheet feeding seat, the lower pressing wheel, the lower sheet suction seat, the lower pressing sheet cylinder, the lower push pressing cylinder, the lower pressing sheet shaft, the lower intermediate idler wheel, and the lower film winding disc form the lower patch assembly. The lower lifting cylinder, the lower support seat, the lower cutting cylinder, the lower sheet feeding cylinder, the lower pressing sheet shaft, the lower intermediate idler wheel, and the lower film winding disc are fixed on the support seat. The upper blade seat, the upper pressing claw, the upper piece support seat, the upper sheet suction seat, the upper connecting rod, the upper push block, the upper blade, the upper intermediate connecting seat, the upper cutting cylinder, the upper sheet feeding cylinder, the upper sheet feeding seat, the upper pressing sheet cylinder, the upper support seat, the upper pressing sheet shaft, the upper pressing wheel, the upper push pressing cylinder, the upper film winding disc, the upper intermediate idler wheel, and the upper lifting cylinder form the upper patch assembly. The upper cutting cylinder, the upper support seat, the upper sheet feeding cylinder, the upper pressing sheet shaft, the upper film winding disc, the upper intermediate idler wheel, and the upper lifting cylinder are fixed on the support seat.

[0047] In the lower patch assembly: the lower lifting cylinder (the first vertical driving structure 21), the lower piece support (the support seat 222), and the lower suction piece seat (the negative pressure part 221) form the patch mechanism (the negative pressure adsorption assembly 20). The lower lifting cylinder is fixed on the support seat, and the lower piece support is installed at the end of its piston rod. The lower suction piece seat is installed on the lower piece support, which has many vacuum suction holes for sucking the film, and then moves upward to be pasted under the electrode. In the lower patch assembly: the lower support seat, the lower push block, the lower connecting rod (the fixing structure 32), the lower pressing claw, and the lower pressing piece cylinder (the second vertical driving structure 31) form the film pressing head mechanism (the fixing assembly 30). When the film needs to be cut, the lower pressing piece cylinder pushes the connecting rod mechanism composed of the lower push block, the lower connecting rod, and the lower pressing claw to press the film head on the lower suction piece seat to prevent the film from retracting. In the lower patch assembly: the lower blade (the tool structure 52), the lower intermediate connecting seat, the lower cutting cylinder (the fifth horizontal driving structure 51), and the lower blade seat form the film cutting mechanism (the cutting assembly 50), and the lower cutting cylinder pushes the lower blade forward to cut the film. In the lower patch assembly: the lower film feeding cylinder (the first horizontal driving structure 41), the lower film feeding seat (the first clamping part 421), the lower pressing piece wheel (the second clamping part 422), the lower push and press cylinder (the second horizontal driving part 423), the lower pressing piece shaft (the third shaft body 45), the lower intermediate idler wheel (the second shaft body 44), and the lower film winding disc (the first shaft body 43) form the film feeding mechanism (the traction assembly 40). The lower push and press cylinder pushes the lower pressing piece wheel to clamp the film on the lower film feeding seat, and the lower film feeding cylinder pushes the lower film feeding seat to pull the film out from the lower film winding disc to complete the film feeding operation.

[0048] In the upper patch assembly: the upper piece support (support seat 222), the upper suction piece seat (negative pressure part 221), and the upper lifting cylinder (first vertical driving structure 21) form the patch mechanism (negative pressure adsorption assembly 20). The upper lifting cylinder is fixed on the support seat, and the upper piece support is installed at the end of its piston rod. The upper suction piece seat is installed on the upper piece support, which has many vacuum suction holes for sucking the film, and then moves from top to bottom to stick on the top of the electrode. In the upper patch assembly: the upper pressing claw, the upper connecting rod (fixing structure 32), the upper pushing block, the upper pressing piece cylinder (second vertical driving structure 31), and the upper support seat form the film head pressing mechanism (fixing assembly 30). When the film needs to be cut, the upper pressing piece cylinder pushes the connecting rod mechanism composed of the upper pushing block, the upper connecting rod, and the upper pressing claw to press the film head on the upper suction piece seat to prevent the film from retracting. In the upper patch assembly: the upper blade seat, the upper blade (tool structure 52), the upper intermediate connecting seat, and the upper cutting cylinder (fifth horizontal driving structure 51) form the film cutting mechanism (cutting assembly 50), and the upper cutting cylinder pushes the upper blade forward to cut the film. In the upper patch assembly: the upper pressing piece shaft (third shaft body 45), the upper pressing piece wheel (second clamping part 422), the upper pushing and pressing cylinder (second horizontal driving part 423), the upper film winding disc (first shaft body 43), the upper intermediate idler wheel (second shaft body 44), the upper film feeding cylinder (first horizontal driving structure 41), and the upper film feeding seat (first clamping part 421) form the film feeding mechanism (traction assembly 40). The upper pushing and pressing cylinder pushes the upper pressing piece wheel to press the film on the upper film feeding seat, and the upper film feeding cylinder pushes the upper film feeding seat to pull the film out from the upper film winding disc to complete the film feeding operation.

[0049] The core technical elements of this application are:

[0050] First, this professional technology is composed of a longitudinal driving mechanism, a transverse driving mechanism, a lower patch assembly, and an upper patch assembly;

[0051] Second, the function of the longitudinal driving mechanism is to complete the longitudinal movement of the entire device;

[0052] Third, the function of the transverse driving mechanism is to complete the transverse movement of the entire device;

[0053] Fourth, the function of the lower patch assembly is to stick the cut film from bottom to top on the lower surface of the battery electrode;

[0054] Fifth, the function of the upper patch assembly is to stick the cut film from top to bottom on the upper surface of the battery electrode;

[0055] Sixth, the longitudinal movement and the transverse movement cooperate to extend the entire device into the working turntable for installing the battery, so that the battery electrode is just between the upper suction piece seat and the lower suction piece seat;

[0056] VII. The lower pressing wheel and the upper pressing wheel are each a cam installed on the lower film feeding seat and the upper film feeding seat respectively, reset by a spring, and rely on the cam to press the film when driven to rotate by a cylinder.

[0057] Now, taking the lower film pasting assembly as an example to illustrate the working process, the working process of the upper film pasting assembly is exactly the same. At the initial stage of work, the entire device is outside the battery turntable (not shown in the figure). The lower film winding disc is filled with film, and the film is manually pulled through the lower intermediate idler wheel and the lower film pressing shaft to the lower film feeding seat, between the lower pressing wheels, and extends a certain length to the lower film sucking seat. At this time, the lower lifting cylinder is in the lowered position. Then, the lower film pressing cylinder and the lower pushing cylinder are started to clamp the film. When the battery rotates to the film pasting station, the longitudinal cylinder and the transverse cylinder push the entire device to the turntable film pasting station. At this time, the battery electrode plate is just between the upper film sucking seat and the lower film sucking seat, and the lower film sucking seat vacuums and sucks the film. Then, the lower cutting cylinder is started, and at this time, the lower blade cuts the film, and then the film cutting mechanism resets. Immediately afterwards, the lower film pressing cylinder drives the film pressing head mechanism to reset. Then, the lower lifting cylinder rises to paste the film on the lower surface of the battery electrode plate, and then resets. Subsequently, the lower film feeding cylinder extends to pull the film forward to the lower film sucking seat, and then the lower film pressing cylinder presses the film on the lower film sucking seat again. After that, the lower pushing cylinder retracts and resets. When the lower pressing wheel no longer presses the film, the lower film feeding cylinder retracts and resets, and the lower pushing cylinder pushes the lower pressing wheel again to press the film tightly. If this device does not affect the rotation of the battery turntable, the longitudinal drive mechanism and the transverse drive mechanism do not reset and wait for the next battery to arrive. If this device affects the rotation of the battery turntable, the longitudinal drive mechanism and the transverse drive mechanism reset and wait for the next battery to arrive. The above is one working cycle. When the next battery comes to paste the film, the above process is repeated again.
