Description

Technical Field

[0001] The present application relates to the technical field of battery manufacturing, and in particular to a battery cell gluing device. Background Art

[0002] At present, the manufacturing process of the battery cells of existing batteries such as lithium batteries, nickel-metal hydride batteries, and nickel-chromium batteries requires a gluing operation, that is, sticking adhesive tape on the surface of the battery cell to prevent the battery cell structure from becoming loose.

[0003] In the prior art, when gluing battery cells, one method is to do it manually. However, the manual method has low production efficiency and low product quality. The other method is to use a gluing machine. However, the existing gluing machine is prone to the defect of loose gluing, which affects the quality of the battery cells. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a battery cell gluing device that can achieve the technical effect of improving production efficiency and production quality.

[0005] An embodiment of the present application provides a battery cell gluing device, including a glue pulling mechanism and a glue sticking mechanism: the glue pulling mechanism includes a first clamping piece and a cutting piece, the first clamping piece is used to clamp the tape and pull the tape to the glue sticking mechanism, the cutting piece is arranged on the glue pulling path, and is used to cut the tape; the glue sticking mechanism includes an adsorption piece, a second clamping piece and a glue sticking piece, the adsorption piece is used to adsorb the tape and stick the tape to the first surface of the battery cell, the second clamping piece is used to clamp one end of the tape, and the glue sticking piece is arranged between the second clamping piece and the adsorption piece, and is used to stick the tape along the second surface of the battery cell.

[0006] In the above implementation process, the battery cell gluing device adsorbs the tape and sticks it to the first surface of the battery cell through the adsorption part, and sticks the tape to the second surface of the battery cell through the second clamping part and the gluing part. It can stick the tape to the surface of the battery cell with high quality, improve the gluing quality of the battery cell, and reduce the defective rate, thereby achieving the technical effect of improving production efficiency and production quality.

[0007] Furthermore, the adhesive sticking mechanism also includes a pressing block, which is arranged at one end of the adsorption member and is used to press the end of the adhesive tape and stick the end of the adhesive tape to the first surface of the battery cell.

[0008] In the above implementation process, after the first clamping member clamps the tape and pulls it to the gluing mechanism, the adsorbent on the gluing mechanism adsorbs the tape; because the end of the tape is still on the first clamping member, the adsorbent does not adsorb the end of the tape, and when the gluing mechanism adheres the tape to the first surface of the battery cell, the end of the tape may not be well adhered to the first surface of the battery cell. Therefore, by arranging a pressing block at one end of the adsorbent, the end of the tape is adhered to the first surface of the battery cell, thereby further improving the gluing quality.

[0009] Furthermore, the glue application mechanism also includes a first mounting plate, a guide member and a first sliding member. The first mounting plate is used to install the adsorption member and the pressure block member. The guide member is installed on the first mounting plate and arranged behind the pressure block member and is connected to the pressure block member. The first sliding member is arranged below the first mounting plate, and the first mounting plate can slide along the first sliding member.

[0010] In the above implementation process, the first mounting plate can slide along the first sliding member, and the adsorption member and the pressing block member are installed on the first mounting plate, and the adsorption member and the pressing block member are driven while the first mounting plate slides; the guide member is respectively connected to the first mounting plate and the pressing block member, and the guide member can drive the pressing block member to the battery cell, press the first surface of the battery cell, and reset the pressing block member under the drive of the first mounting plate.

[0011] Furthermore, the guide member is an elastic guide member, and the elastic guide member is elastically connected to the pressing block member to reset the pressing block member.

[0012] In the above implementation process, the guide member and the pressing block member are elastically connected, so that when the first mounting plate drives the guide member forward, the guide member can press forward against the pressing block member to continue moving forward, and finally press against the first surface of the battery cell to stick the tape on the first surface of the battery cell; at the same time, the elasticity of the guide member can prevent the pressing block member from crushing the battery cell, thereby reducing the defective rate of the battery cell adhesive.

[0013] Furthermore, the glue-applying mechanism also includes a second mounting plate, a second sliding member and a limiting member, the second mounting plate is used to install the second clamping member, the second sliding member is installed on the second mounting plate, the second clamping member can slide along the second sliding member, and the limiting member is arranged in front of the first mounting plate and installed on the second clamping member, and is used to make the second clamping member slide along the second sliding member under the push of the first mounting plate.

[0014] In the above implementation process, the limit member is installed on the second clamping member, and the limit member is arranged between the first mounting plate and the second clamping member, so that when the first mounting plate moves forward, it can resist the limit member and push the second clamping member to move forward along the second sliding member.

[0015] Furthermore, the second sliding member is an elastic sliding member, which is used to reset the second clamping member when the first mounting plate does not push the limiting member.

[0016] In the above implementation process, the second sliding member is elastically connected to the second clamping member, and when the first mounting plate does not push the limiting member, the second clamping member can be reset under the elastic force of the second sliding member.

[0017] Furthermore, the glue sticking mechanism also includes a third sliding member and a base, the adsorption member is installed on the base, the third sliding member is installed on the first mounting plate, and the base can slide along the third sliding member.

[0018] In the above implementation process, the adsorption member is installed on the base, and the base is installed on the third sliding member, so that when the adsorption member is against the first surface of the battery cell, the adsorption member can slide relative to the first mounting plate as the first mounting plate continues to slide forward.

[0019] Furthermore, the glue pulling mechanism also includes a first driving mechanism, a second driving mechanism, and a third driving mechanism. The first driving mechanism is used to drive the first clamping member to move forward or backward, the second driving mechanism is used to drive the first clamping member to open or close, and the third driving mechanism is used to drive the cutting member to extend or retract.

[0020] In the above implementation process, the first driving mechanism, the second driving mechanism, and the third driving mechanism may be pneumatic actuators, hydraulic actuators, or electric actuators.

[0021] Furthermore, the adhesive pulling mechanism also includes a third clamping member and a fourth driving mechanism. The third clamping member is arranged in front of the cutting member and is used to clamp the tape so that the cutting member cuts the tape; the fourth driving mechanism is used to drive the third clamping member to open or close.

[0022] In the above implementation process, the third clamping member and the fourth driving mechanism can be arranged in front of the cutting member and clamp the tape; the cutting member is between the third clamping member and the second clamping member, and the tape is clamped by the third clamping member and the second clamping member, so that the cutting member can cut the tape and prevent the tape from curling and deforming, thereby improving the cutting effect.

[0038] An embodiment of the present application provides a battery cell gluing device, which can be used for battery cell gluing operations in manufacturing batteries, where the tape is glued to the surface of the battery cell; the battery cell gluing device absorbs the tape through an adsorption member and sticks it to the first surface of the battery cell, and sticks the tape to the second surface of the battery cell through a second clamping member and a gluing member, which can improve the gluing quality of the battery cell and reduce the defective rate, thereby achieving the technical effect of improving production efficiency and production quality.

[0039] For example, after the battery cell is stacked, it needs to be glued. The battery cell manufacturing process of rectangular batteries such as lithium batteries, nickel-metal hydride batteries, and nickel-chromium batteries is roughly: stacking, winding, and gluing; the battery cell gluing device provided in the embodiment of the present application can solve the defect that the gluing method of the existing gluing device is prone to loose gluing, thereby improving the gluing quality of the battery cell gluing.

[0040] See also Figure 1 , Figure 1 The schematic structural diagram of a battery cell gluing device provided in an embodiment of the present application. The battery cell gluing device includes a gluing mechanism and a gluing mechanism.

[0041] Exemplarily, the glue pulling mechanism includes a first clamping member 101 and a cutting member 102, wherein the first clamping member is used to clamp the adhesive tape and pull the adhesive tape to the glue applying mechanism, and the cutting member 102 is arranged on the glue pulling path and is used to cut the adhesive tape.

[0042] Exemplarily, the glue pulling mechanism also includes a first driving mechanism 103, a second driving mechanism 104, and a third driving mechanism 105, wherein the first driving mechanism 103 is used to drive the first clamping member 101 forward or backward, the second driving mechanism 104 is used to drive the first clamping member 101 to open or close, and the third driving mechanism 105 is used to drive the cutting member 102 to extend or retract.

[0043] In some embodiments, the first driving mechanism 103 , the second driving mechanism 104 , and the third driving mechanism 105 may be electric actuators, hydraulic actuators, or pneumatic actuators.

[0044] Exemplarily, the first clamping member 101 is a clamp that can be opened or closed under the drive of the second driving mechanism 104; when the first clamping member 101 is opened under the drive of the second driving mechanism 104, the first clamping member 101 is moved under the drive of the first driving mechanism 103 and aligns with the tape so that the tape is in the middle of the clamp of the first clamping member 101; then the first clamping member 101 is closed under the drive of the second driving mechanism 104, clamps the tape, and pulls the tape to the gluing mechanism under the drive of the first driving mechanism 103.

[0045] Exemplarily, after the first clamping member 101 pulls the tape to the gluing mechanism under the drive of the first driving mechanism 103, the first clamping member 101 opens under the drive of the second driving mechanism 104 and continues to move forward, thereby moving the first clamping member 101 out of the position of the gluing mechanism.

[0046] In some embodiments, there is also an air avoidance driving mechanism in front of the first driving mechanism 103; the first driving mechanism 103 first moves a length to pull the glue, and then when the end of the tape is about to be pasted onto the battery cell, the air avoidance driving mechanism drives the first clamping member 101 to continue moving forward, and then moves a length to avoid the air, so that the glue sticking mechanism will not be blocked by the first clamping member 101 when pasting the end of the tape.

[0047] Exemplarily, when the first clamping member 101 pulls the tape to the gluing mechanism under the drive of the second driving mechanism 104, the cutting member 102 is extended under the drive of the third driving mechanism 105, thereby cutting the tape, that is, cutting off a part of the complete tape for battery cell gluing; when the tape cutting is completed, the cutting member 102 is retracted under the drive of the third driving mechanism 105 to complete the resetting.

[0048] In some embodiments, the cutting member 102 is a serrated cutter.

[0049] In some embodiments, the glue pulling mechanism also includes a third clamping member 106 and a fourth driving mechanism 107. The third clamping member 106 is arranged in front of the cutting member 102 and is used to clamp the tape so that the cutting member 102 cuts the tape; the fourth driving mechanism 107 is used to drive the third clamping member 106 to open or close.

[0050] Exemplarily, the third clamping member 106 is a clamping block that can be opened and closed; when the third clamping member 106 is opened, the first clamping member 101 pulls the tape to the glue sticking mechanism; then the third clamping member 106 is closed to clamp the tape to fix the tape. On the one hand, when the cutting member 102 cuts the tape, wrinkles on the tape or adhesion between the tapes can be avoided; on the other hand, the third clamping member 106 can continue to clamp the tape, and when the first clamping member 101 pulls the tape next time, it can be convenient for the first clamping member 101 to clamp the tape.

[0051] Exemplarily, the glue sticking mechanism includes a suction member 201, a second clamping member 202 and a glue sticking member 203; see Figure 1 and Figure 2 ,in Figure 2 A schematic structural diagram of a glue sticking mechanism provided in an embodiment of the present application, wherein the adsorbent 201 is used to adsorb the tape and stick the tape to the first surface of the battery cell, the second clamping member 202 is used to clamp one end of the tape, and the glue sticking member 203 is arranged between the second clamping member 202 and the adsorbent 201, and can slide along the second surface of the battery cell, and is used to stick the tape along the second surface of the battery cell.

[0052] In some embodiments, a suction cup is disposed on the surface of the adsorbent 201 for adsorbing the tape.

[0053] Exemplarily, the shape of the adhesive member 203 matches the shape of the second surface of the battery cell, so that when the adhesive member 203 slides on the second surface of the battery cell, the tape is better adhered to the second surface of the battery cell, thereby improving the adhesive quality.

[0054] In some embodiments, the adhesive sticking mechanism further includes a pressing block 204, wherein the pressing block 204 is disposed at one end of the adsorption member 201, and is used to press the end of the adhesive tape and stick the end of the adhesive tape to the first surface of the battery cell.

[0055] Exemplarily, a glue piece 203 and a pressing piece 204 are respectively provided at two ends of the adsorption piece 201, and the positions of the glue piece 203 and the pressing piece 204 are opposite to each other.

[0056] In some implementation scenarios, the gluing workflow of the gluing mechanism is as follows: when the gluing mechanism pulls the tape to the gluing mechanism, the adsorbent 201 adsorbs the tape, and then the first clamping member 101 releases the tape. It should be noted that at this time, the end of the tape is outside the adsorption range of the adsorbent 201; after the cutting member 102 cuts the tape, the adsorbent 201, the second clamping member 202, the gluing member 203 and the pressing member 204 are driven to stick the tape to the surface of the battery cell, wherein the adsorbent 201 sticks the tape to the first surface of the battery cell, and the pressing member 204 sticks the end of the tape to the first surface of the battery cell; the second clamping member 202 pulls the tape to the second surface of the battery cell, and the gluing member 203 slides along the second surface of the battery cell, thereby sticking the tape to the second surface of the base, completing the battery cell gluing operation.

[0057] Exemplarily, the gluing mechanism also includes a first mounting plate 205, a guide member 206 and a first sliding member 207. The first mounting plate 205 is used to install the adsorption member 201 and the pressure block member 204. The guide member 206 is installed on the first mounting plate 205 and is arranged behind the pressure block member 204 and is connected to the pressure block member 204. The first sliding member is arranged below the first mounting plate 205, and the first mounting plate 205 can slide along the first sliding member 207.

[0058] Exemplarily, the guide member 206 is an elastic guide member, which is elastically connected to the pressing block member 204 and is used to reset the pressing block member 204 .

[0059] Exemplarily, the glue-applying mechanism also includes a second mounting plate 208, a second sliding member 209 and a limiting member 210. The second mounting plate 208 is used to mount the second clamping member 202. The second sliding member 209 is mounted on the second mounting plate 208. The second clamping member 202 can slide along the second sliding member 209. The limiting member 210 is arranged in front of the first mounting plate 205 and is installed on the second clamping member 202, and is used to make the second clamping member 202 slide along the second sliding member 209 under the push of the first mounting plate 205.

[0060] Exemplarily, the second sliding member 209 is an elastic sliding member, which is used to reset the second clamping member 202 when the first mounting plate 205 does not push the limiting member 210 .

[0061] Exemplarily, the glue sticking mechanism further includes a third sliding member 211 and a base 212 . The adsorption member 201 is mounted on the base 212 . The third sliding member 211 is mounted on the first mounting plate 205 . The base 212 can slide along the third sliding member 211 .

[0062] In some embodiments, the third sliding member 211 is a sliding guide rail, and the base 212 is engaged with the sliding guide rail and can slide on the sliding guide rail.

[0063] Exemplarily, the gluing mechanism also includes a fifth driving mechanism 213, a first connecting member 214, and a second connecting member 215; wherein the fifth driving mechanism 213 is used to drive the first mounting plate 205 forward or backward, the first connecting member 214 is used to connect the first mounting plate 205 and the base 212, and the second connecting member 215 is used to connect the first mounting plate 205 and the fifth driving mechanism 213.

[0064] In some embodiments, the first connecting member 214 is an elastic connecting member, and the first connecting member 214 is elastically connected to the base 212 .

[0065] In some implementation scenarios, when the gluing operation is performed: when the fifth driving mechanism drives the first mounting plate 205 to move forward, until the adsorption member 201 presses the first surface of the battery cell, the tape is adhered to the first surface of the battery cell; then the fifth driving mechanism 213 continues to drive the first mounting plate 205 to move forward. At this time, since the adsorption member 201 has pressed the battery cell and cannot continue to move forward, the base 212 drives the adsorption member 201 to move backward relative to the first mounting plate 205 along the third sliding member 211; the glue member 203 is installed on the first mounting plate 205, and the fifth driving mechanism 213 continues to drive the first mounting plate 205 to move forward, so that the glue member 203 slides along the second surface of the battery cell, thereby sticking the tape to the second surface of the battery cell; the pressing block 204 continues to move forward under the push of the guide member 206, thereby sticking the end of the tape to the first surface of the battery cell.

[0066] In some embodiments, when the gluing operation is completed, the gluing mechanism begins to reset: the fifth driving mechanism 213 drives the first mounting plate 205 to move backward, completing the resetting of the first mounting plate 205 and the gluing member 203; since the first connecting member 214 is an elastic connecting member, under the action of the first connecting member 214, the base 212 moves forward relative to the first mounting plate 205, and after the end face of the base 212 is aligned with the end face of the first mounting plate 205, under the action of the first connecting member 214, the base 212 and the first mounting plate 205 are relatively stationary, completing the resetting of the adsorption member 201; since the guide member 206 is an elastic guide member, when the fifth driving mechanism 213 drives the first mounting plate 205 to move backward, under the action of the elastic guide member, the pressing block member 204 is reset.

[0067] Exemplarily, when the gluing mechanism is working, the first mounting plate 205 moves forward driven by the fifth driving mechanism 213, and the base 212 moves synchronously with the first mounting plate 205 under the push of the first connecting member 214; when the adsorption member 201 is against the first surface of the battery cell and the tape is attached to the first surface of the battery cell, the first mounting plate 205 continues to move forward, and the base 212 slides backward along the third sliding member 211 relative to the first mounting plate 205, and the first connecting member 214 accumulates elastic force at this time; when the gluing mechanism completes the gluing operation, the first mounting plate 205 moves backward driven by the fifth driving mechanism 213, and at this time, due to the elastic force of the first connecting member 214, the base 212 slides forward along the third sliding member 211 relative to the first mounting plate 205 until the base 212 is reset on the first mounting plate 205; the first mounting plate 205 continues to slide backward, and the first connecting member 214 drives the base 212 to slide synchronously with the first mounting plate, and finally completes the reset of the gluing mechanism.

[0068] Illustratively, when the gluing mechanism is working, the first mounting plate 205 moves forward driven by the fifth driving mechanism 213; when the adsorption member 201 is against the first surface of the battery cell and the tape is attached to the first surface of the battery cell, the first mounting plate 205 continues to move forward, and the base 212 slides backward along the third sliding member 211 relative to the first mounting plate 205, and the guide member 206 continues to push the pressing block member 204 forward to press the first surface of the battery cell and attach the end of the tape to the first surface of the battery cell. The elastic member on the guide member 206 can prevent the pressing block member from crushing the battery cell; after completing the gluing operation of the battery cell, the first mounting plate 205 moves backward, and at this time the guide member 206 drives the pressing block member 204 to reset.

[0069] In some embodiments, the battery cell gluing device further includes a sixth driving mechanism 501 and a fixing member 502; the sixth driving mechanism 501 is used to drive the fixing member 502 to extend or retract, and the fixing member 502 is used to press the battery cell to prevent the battery cell from moving during the gluing operation, thereby further ensuring the production quality of the battery cell gluing.

[0070] See also Figure 3 , Figure 3 A schematic structural diagram of a cutting member and a second clamping member provided in an embodiment of the present application.

[0071] Exemplarily, the gluing mechanism further includes a seventh driving mechanism 216 for driving the second clamping member 202 to open or close.

[0072] Exemplarily, when the gluing mechanism is performing gluing: the fifth driving mechanism 213 drives the first mounting plate 205 to move forward, and the end surface of the first mounting plate 205 presses the limiting member 210 forward, and drives the limiting member 210 to move forward; at this time, the second clamping member 202 moves forward driven by the limiting member 210, thereby pulling the tape to above the second surface of the battery cell, and at this time, the glue sticking member 203 between the adsorption member 201 and the second clamping member 202 slides along the second surface of the battery cell driven by the first mounting plate 205, thereby sticking the battery cell to the second surface of the battery cell.

[0073] Exemplarily, when the gluing mechanism completes gluing and resets: the fifth driving mechanism 213 drives the first mounting plate 205 to move backward, and the second clamping member 202 slides backward relative to the second mounting plate 208 under the elastic thrust of the second sliding member 209, completing the reset of the second clamping member 202.

[0074] In some embodiments, the battery cell gluing device includes two sets of operating mechanisms, which perform gluing operations on the battery cell from both ends of the battery cell. Figure 4 , Figure 4 The schematic structural diagram of a battery cell gluing device provided in an embodiment of the present application. The battery cell gluing device comprises a gluing mechanism, a gluing mechanism and a reeling mechanism.

[0075] Exemplarily, the glue pulling mechanism, the glue sticking mechanism and the unwinding mechanism each include two sets of mechanisms, that is, the glue pulling mechanism includes a first glue pulling mechanism 11 and a second glue pulling mechanism 12, the glue sticking mechanism includes a first glue sticking mechanism 21 and a second glue sticking mechanism 22, and the unwinding mechanism includes a first unwinding mechanism 31 and a second unwinding mechanism 32. Among them, the first glue pulling mechanism 11, the first glue sticking mechanism 21, and the first unwinding mechanism 31 are a set of operating units, which stick the tape 41 on the first surface and the second surface of the battery cell; the second glue pulling mechanism 12, the second glue sticking mechanism 22 and the second unwinding mechanism 32 are a set of operating units, which stick the tape 42 on the third surface and the second surface of the battery cell.

[0076] In some embodiments, the first surface and the third surface of the battery cell are surfaces at two ends of the battery cell that are opposite to each other.
