Technical Field

[0001] This application belongs to the field of lithium battery production equipment technology, and in particular relates to a cell jig and a cell conveying line. Background Technology

[0002] In the production process of battery cell modules, the battery cell modules are generally transported from one process to the next via a conveyor line. In order to ensure the accurate position of the battery cell modules at each process, fixtures are installed on the conveyor line to support and limit the position of the battery cell modules.

[0003] However, battery cell modules come in a variety of sizes and shapes, and each existing fixture used for battery cell modules can only be adapted to one size of battery cell module. When the production line needs to change the size of the battery cell modules produced, the fixtures on each conveyor line must be removed and replaced with the corresponding fixtures, which is a cumbersome operation. Moreover, different fixtures need to be stored separately, occupying a lot of storage space. Therefore, the existing fixtures used for battery cell modules have the problem of poor versatility. Utility Model Content

[0004] The purpose of this application is to provide a battery cell fixture to solve the problem of poor versatility of existing fixtures for battery cell modules; another purpose of this application is to provide a battery cell delivery line including the battery cell fixture.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] In a first aspect, this application proposes a battery cell fixture, which includes a first clamping assembly and a second clamping assembly spaced apart along a first direction, wherein:

[0007] The first clamping assembly includes a first carrier, a first clamping member, and a second clamping member. The first carrier is configured to carry a single first battery cell. The first clamping member is disposed at a first end of the first carrier along a first direction. The second clamping member is elastically mounted at a second end of the first carrier along the first direction. The first clamping member and the second clamping member respectively abut against both ends of the first battery cell carried by the first carrier along the first direction to clamp the first battery cell on the first carrier.

[0008] The second clamping assembly includes a second carrier, a third clamping member, and a fourth clamping member. The bearing surfaces of the first carrier and the second carrier are at the same height. The second carrier is configured to carry a single first battery cell. The third clamping member is disposed close to the second clamping member and is elastically mounted on a first end of the second carrier along a first direction. The fourth clamping member is disposed on a second end of the second carrier along the first direction. The third clamping member and the fourth clamping member respectively abut against the two ends of the first battery cell carried by the second carrier along the first direction to clamp the first battery cell on the second carrier.

[0009] The first and second carriers are also configured to jointly support the second battery cell. The upper surface of the second clamping member is lowered no higher than the bearing surface of the first carrier and the upper surface of the third clamping member is lowered no higher than the bearing surface of the second carrier. The second battery cell is pressed against the first and second carriers at least. The first and fourth clamping members abut against the two ends of the second battery cell along the first direction to clamp the second battery cell on the first and second carriers.

[0010] The battery cell fixture proposed in this application is provided with a first clamping component and a second clamping component. The first clamping component and the second clamping component can each clamp a first battery cell individually. The first clamping component and the second clamping component can also cooperate to clamp a second battery cell, so that the battery cell fixture can be adapted to two specifications of battery cells and improve the versatility of the battery cell fixture.

[0011] Optionally, the first clamping member is slidably mounted on the first end of the first carrier member along the first direction, and the second clamping member is elastically mounted on the second end of the first carrier member in a liftable manner;

[0012] The third clamping member is elastically movable and slidably mounted on the first end of the second carrier member along the first direction, and the fourth clamping member is fixedly mounted on the second end of the second carrier member.

[0013] By configuring the first and second clamping members, a first battery cell can be individually clamped by the cooperation of the first and second clamping members; by configuring the third and fourth clamping members, a first battery cell can be individually clamped by the cooperation of the third and fourth clamping members; at the same time, a second battery cell can be individually clamped by the cooperation of the first and fourth clamping members, providing a simple mounting structure for the first, second, third, and fourth clamping members.

[0014] Optionally, the first bearing member includes a first base, a first bearing platform, a first horizontal elastic member, and a first vertical elastic member, wherein:

[0015] The first support platform is fixedly installed on the first base. The first support platform is configured to support the first battery cell or the second battery cell. The first horizontal elastic member is horizontally disposed between the first clamping member and the first base. The first end of the first horizontal elastic member is connected to the first clamping member, and the second end of the first horizontal elastic member is connected to the first base. The first horizontal elastic member is configured to keep the first clamping member close to the first support platform so as to abut against the first end of the first battery cell or the second battery cell on the first support platform.

[0016] The first vertical elastic member is vertically disposed between the second clamping member and the first base. The first end of the first vertical elastic member is connected to the first base, and the second end of the first vertical elastic member is connected to the second clamping member. The first vertical elastic member is configured to cause the second clamping member to protrude vertically from the first support platform to abut against the second end of the first battery cell on the first support platform.

[0017] The second load-bearing component includes a second base, a first lifting component, a second load-bearing platform, a second vertical elastic component, and a second horizontal elastic component, wherein:

[0018] The second support platform is fixedly installed on the second base. The second support platform is configured to support the first battery cell or the second battery cell. The first lifting member is movably installed on the second base. The third clamping member is slidably installed on the first lifting member along the first direction.

[0020] By incorporating a first horizontal elastic element, the first clamping member can be floatingly mounted on the first base, moving closer to or further away from the first support platform along a first direction. The elastic force of the first horizontal elastic element automatically clamps the first end of the battery cell on the first support platform.

The elastic force of the first vertical elastic element causes the second clamping member to protrude vertically from the first support platform, automatically clamping the second end of the first battery cell on the first support platform. Furthermore, when clamping the second battery cell, the weight of the second battery cell overcomes the elastic force of the first vertical elastic element, pressing the second clamping member down until it is flush with the support surface of the first support platform, thus automatically avoiding the second battery cell. This provides a simple structure with stable and reliable clamping.

By setting a second horizontal elastic member, the third clamping member can be floated on the first lifting member along the first direction to approach or move away from the second support platform, and then the first end of the first battery cell on the second support platform is automatically clamped by the elastic force of the second horizontal elastic member. When clamping the second battery cell, the third clamping member is pressed down to be flush with the bearing surface of the second support platform by the weight of the second battery cell. This achieves automatic avoidance of the second battery cell and provides a second clamping assembly with a simple structure and stable and reliable clamping.

The first end of the fourth horizontal elastic member is connected to the fourth clamping member, and the second end of the fourth horizontal elastic member is connected to the second base. The fourth horizontal elastic member is configured to keep the fourth clamping member close to the second support platform so as to abut against the first battery cell or the second end of the second battery cell on the second support platform.

[0030] By incorporating a third horizontal elastic element, the first clamping member can be floatingly mounted on the first base along a first direction, moving closer to or further away from the first support platform. The elastic force of the third horizontal elastic element then automatically clamps the first end of the battery cell on the first support platform. Similarly, by incorporating a third vertical elastic element, the second clamping member can be floating vertically on the first base. The elastic force of the third vertical elastic element causes the second clamping member to protrude vertically from the first support platform, automatically clamping the second end of the first battery cell on the first support platform. Furthermore, when clamping the second battery cell, the weight of the second battery cell overcomes the elastic force of the first vertical elastic element, pressing the second clamping member down until it is flush with the support surface of the first support platform, thus automatically avoiding the second battery cell. This provides a simple, stable, and reliable first clamping assembly. By setting a fourth vertical elastic element, the third clamping element can be installed on the second base in a vertically floating manner. Then, relying on the elastic force of the fourth vertical elastic element, the third clamping element protrudes vertically from the second support platform to automatically clamp the first end of the first battery cell on the second support platform.

The fifth vertical elastic member is configured to make the second clamping member protrude vertically from the first support platform.

[0036] The fifth horizontal elastic element is horizontally disposed between the second clamping element and the second lifting element. The first end of the fifth horizontal elastic element is connected to the second clamping element, and the second end of the fifth horizontal elastic element is connected to the second lifting element. The fifth horizontal elastic element is configured to keep the second clamping element close to the first bearing platform. The cooperation between the fifth vertical elastic element and the fifth horizontal elastic element causes the second clamping element to abut against the second end of the first battery cell on the first bearing platform.

[0037] The second bearing member includes a second base, a second bearing platform, a sixth vertical elastic member, and a sixth horizontal elastic member, wherein:

[0038] The second support platform is fixedly installed on the second base. The second support platform is configured to support the first battery cell or the second battery cell.

By incorporating a fifth horizontal elastic element, the second clamping element can be flexibly mounted on the second lifting element, moving closer to or further away from the first support platform along a first direction. The elastic force of the fifth horizontal elastic element automatically clamps the second end of the first battery cell on the first support platform. Furthermore, when clamping the second battery cell, the weight of the second battery cell overcomes the elastic force of the fifth vertical elastic element, pressing the second clamping element down until it is flush with the support surface of the first support platform, thus achieving automatic avoidance of the second battery cell. This provides a simple, stable, and reliable first clamping assembly. The third clamping member is mounted on the second base in a vertically floating manner by a sixth vertical elastic member.

Each set of elastic limiting members includes at least one elastic limiting member. The first bearing member and the second bearing member are also configured to jointly bear the third battery cell. The third battery cell carried by the first bearing member and the second bearing member presses against the second clamping member and the third clamping member so that the upper surfaces of the second clamping member and the third clamping member are flush with the bearing surface of the first bearing member. The corresponding elastic limiting member abuts against the first end of the third battery cell along the first direction, and the fourth clamping member abuts against the second end of the third battery cell along the first direction to clamp the third battery cell on the first bearing member and the second bearing member.

[0042] Alternatively, a plurality of sets of elastic limiting members are provided at intervals along the first direction on the bearing surface of the second bearing member. Each set of elastic limiting members includes at least one elastic limiting member. The first bearing member and the second bearing member are also configured to jointly bear the third battery cell. The third battery cell carried by the first bearing member and the second bearing member presses against the second clamping member and the third clamping member so that the second clamping member and the third clamping member are flush with the bearing surface of the first bearing member. The first clamping member abuts against the first end of the third battery cell along the first direction, and the corresponding elastic limiting member abuts against the second end of the third battery cell along the first direction to clamp the third battery cell on the first bearing member and the second bearing member.

[0043] By setting several sets of elastic limiting members on the first or second carrier, any set of elastic limiting members can cooperate with the first or fourth clamping member to clamp the third battery cell jointly supported by the first and second carriers, so that the battery cell fixture can be adapted to at least three specifications of battery cells, further improving the versatility of the battery cell fixture.

[0044] Optionally, the first clamping assembly further includes a first driving source, and the second clamping assembly further includes a second driving source. The first clamping member is slidably mounted on the first end of the first carrier in a first direction, and the second clamping member is vertically mounted on the second end of the first carrier.

The second driving source is used to drive the third clamping member to move vertically up and down.

[0046] By setting a first driving source and a second driving source, the second clamping member and the third clamping member are driven to rise and fall. When it is necessary to clamp the second or third battery cell, the second clamping member and the third clamping member are driven to fall and avoid the second or third battery cell. This provides a driving method that uses a power source to drive the second clamping member and the third clamping member to rise and fall.

[0047] Secondly, this application also proposes a battery cell conveying line, which includes a conveying mechanism, several battery cell fixtures, and two unlocking mechanisms, wherein:

[0051] When the conveying mechanism transports several battery cell fixtures to the processing station, the processing device processes the battery cells on the battery cell fixtures at the processing station according to the preset procedures.

[0052] When the conveying mechanism transports several battery cell fixtures to the unloading station, the unlocking mechanism at the unloading station is configured to push open the first clamping member, the second clamping member, the third clamping member, and the fourth clamping member of the battery cell fixture at the unloading station, so that the battery cell fixture releases its clamping of the battery cell, so that the battery cell can be removed from the battery cell fixture by the handling mechanism.

[0053] A conveying mechanism sequentially transports several battery cell fixtures to a loading station, at least one processing station, and a unloading station, enabling the automatic flow of these fixtures and the batteries they hold between them. Unlocking mechanisms at the loading and unloading stations automatically open the fixtures, facilitating the receipt and removal of processed batteries and improving work efficiency. Furthermore, the fixtures are adaptable to different battery cell specifications, offering good versatility.

[0055] The unlocking component includes a first driving member and a first push block. The driving end of the first driving member is connected to the first push block. The first driving member is configured to drive the first push block to move closer to or further away from the first clamping member or the second clamping member corresponding to the unlocking component.

[0056] The first driving member drives the first push block to approach and abut against the first clamping member or the second clamping member corresponding to the unlocking component, so as to push the first clamping member and the second clamping member away from each other and / or push the third clamping member and the fourth clamping member away from each other, thereby opening the battery cell fixture.

[0057] By setting two unlocking components, each corresponding to a clamping member of the first clamping component and the second clamping component respectively, each unlocking component includes a first driving component and a first pushing block. The first driving component drives the first pushing block to push against the corresponding clamping member, so that the first clamping member and the second clamping member move away from each other and / or push the third clamping member and the fourth clamping member move away from each other, thereby opening the battery cell fixture. This provides a simple and easy-to-implement unlocking mechanism; moreover, the first clamping component and the second clamping component can be controlled independently, which is highly flexible.

[0058] Optionally, the unlocking mechanism includes a base plate, a second driving member, a track plate, and two second push blocks. The first second push block corresponds to the first or second clamping member of the first carrier, and the second second push block corresponds to the third or fourth clamping member of the second carrier, wherein:

[0059] The track plate is slidably mounted on the substrate along the first direction, the fixed end of the second driving member is mounted on the substrate, the driving end of the second driving member is connected to the track plate, and the second driving member is configured to drive the track plate to reciprocate along the first direction.

[0060] The second push block is mounted on the base plate in a liftable manner. Two inclined track grooves are arranged parallel to each other along the first direction on the track plate. Each track groove corresponds to a second push block. The second push block is equipped with a roller that fits and inserts into the corresponding track groove.

[0061] The second driving component drives the track plate to reciprocate along the first direction, and then drives the two second push blocks to move up and down and laterally in sync through the cooperation of the track groove and the roller, so that the two second push blocks move closer or further away from the corresponding clamping component in sync.

[0062] Two second push blocks approach and abut against the corresponding clamping members simultaneously, so as to push the first clamping member and the second clamping member away from each other and push the third clamping member and the fourth clamping member away from each other, thereby opening the battery cell fixture.

[0063] Through the cooperation of the second driving component, the track plate, and the two second push blocks, the two second push blocks are driven to approach and abut against the corresponding clamping components, so that the first clamping component and the second clamping component move away from each other and the third clamping component and the fourth clamping component move away from each other, thus realizing the automatic opening of the battery cell fixture; through the cooperation of the two track grooves and the rollers on the two second push blocks, the first clamping component and the second clamping component of the battery cell fixture are opened and clamped synchronously, providing an unlocking mechanism with high control precision and stable and reliable operation.

[0077] In the production process of battery cell modules, the battery cell modules are generally transported from one process to the next via a conveyor line. In order to ensure the accurate position of the battery cell modules at each process, fixtures are installed on the conveyor line to support and limit the position of the battery cell modules.

[0078] However, battery cell modules come in a variety of sizes and shapes, and each existing fixture used for battery cell modules can only be adapted to one size of battery cell module. When the production line needs to change the size of the battery cell modules produced, the fixtures on each conveyor line must be removed and replaced with the corresponding fixtures, which is a cumbersome operation. Moreover, different fixtures need to be stored separately, occupying a lot of storage space. Therefore, the existing fixtures used for battery cell modules have the problem of poor versatility.

The second support member 120 includes a second base 1200, a first lifting member 1201, and a second support platform 1200. 02. A second vertical elastic element 1203 and a second horizontal elastic element 1204, wherein: a second support platform 1202 is fixedly installed on a second base 1200, and the second support platform 1202 is configured to support a first battery cell 20 or a second battery cell; a first lifting member 1201 is movably installed on the second base 1200; a third clamping member 121 is slidably installed on the first lifting member 1201 along a first direction; a second vertical elastic element 1203 is vertically disposed between the first lifting member 1201 and the second base 1200; a first end of the second vertical elastic element 1203 is connected to the first lifting member 1201; and a second end of the second vertical elastic element 1203 is connected to the second base 1200. 3 is configured such that the first lifting member 1201 and the third clamping member 121 protrude vertically from the second support platform 1202.

The second horizontal elastic member 1204 is configured to keep the third clamping member 121 close to the second support platform 1202. The third clamping member 121 abuts against the first end of the first battery cell 20 on the second support platform 1202 through the cooperation of the second vertical elastic member 1203 and the second horizontal elastic member 1204.

[0084] Specifically, the first horizontal elastic element 1102, the first vertical elastic element 1103, the second vertical elastic element 1203, and the second horizontal elastic element 1204 are all springs.

The first end of the battery cell on the first support platform 1101 is automatically clamped by the elastic force of the first horizontal elastic element 1102. By setting the first vertical elastic element 1103, the second clamping element 112 can be floated up and down on the first base 1100. The second clamping element 112 protrudes vertically from the first support platform 1101 by the elastic force of the first vertical elastic element 1103, automatically clamping the second end of the first battery cell 20 on the first support platform 1101. Furthermore, when clamping the second battery cell, the weight of the second battery cell overcomes the elastic force of the first vertical elastic element 1103, pressing the second clamping element 112 down to be flush with the support surface of the first support platform 1101, thus achieving automatic avoidance of the second battery cell. This provides a simple structure with stable and reliable clamping. The first clamping assembly 11, by setting a second vertical elastic member 1203, enables the first lifting member 1201 to be floatably mounted on the second base 1200. Then, the elastic force of the second vertical elastic member 1203 makes the first lifting member 1201 and the third clamping member 121 protrude vertically from the second support platform 1202. By setting a second horizontal elastic member 1204, the third clamping member 121 can be floatably mounted on the first lifting member 1201 along the first direction, approaching or moving away from the second support platform 1202. Then, the elastic force of the second horizontal elastic member 1204 automatically clamps the first end of the first battery cell 20 on the second support platform 1202. Furthermore, when clamping the second battery cell, the weight of the second battery cell overcomes the elastic force of the second vertical elastic member 1203 to press the third clamping member 121 down to be flush with the support surface of the second support platform 1202, thus achieving automatic avoidance of the second battery cell. This provides a second clamping assembly 12 with a simple structure and stable and reliable clamping.

A third horizontal elastic member is configured to hold the first clamping member 111 close to the first support platform 1101, abutting against the first end of the first battery cell 20 or the second battery cell on the first support platform 1101. A third vertical elastic member is vertically disposed between the second clamping member 112 and the first base 1100. The first end of the third vertical elastic member is connected to the first base 1100, and the second end of the third vertical elastic member is connected to the second clamping member 112. The third vertical elastic member is configured to cause the second clamping member 112 to protrude vertically from the first support platform 1101, abutting against the first battery cell 20 on the first support platform 1101. The second end; the second bearing member 120 includes a second base 1200, a second bearing platform 1202, a fourth vertical elastic member (not shown in the figure) and a fourth horizontal elastic member (not shown in the figure), wherein: the second bearing platform 1202 is fixedly installed on the second base 1200, and the second bearing platform 1202 is configured to carry the first battery cell 20 or the second battery cell; the fourth vertical elastic member is vertically disposed between the third clamping member 121 and the second base 1200, the first end of the fourth vertical elastic member is connected to the second base 1200, and the second end of the fourth vertical elastic member is connected to the third clamping member 121; the fourth vertical elastic member...

The first end of the fourth horizontal elastic member is connected to the fourth clamping member 122, and the second end of the fourth horizontal elastic member is connected to the second base 1200. The fourth horizontal elastic member is configured to keep the fourth clamping member 122 close to the second support platform 1202 to abut against the first battery cell 20 or the second end of the second battery cell on the second support platform 1202.

[0092] Specifically, the third horizontal elastic element, the third vertical elastic element, the fourth vertical elastic element, and the fourth horizontal elastic element are all springs.

[0093] Specifically, the first clamping member 111 is slidably mounted on the first base 1100 along the first direction via a sliding guide pair composed of a guide rail and a slider; the second clamping member 112 is lifted and lowered on the first base 1100 via a sliding guide pair composed of a guide rail and a slider; the third clamping member 121 is lifted and lowered on the second base 1200 via a sliding guide pair composed of a guide rail and a slider; and the fourth clamping member 122 is slidably mounted on the second base 1200 along the first direction via a sliding guide pair composed of a guide rail and a slider.

[0094] As can be seen, by setting a third horizontal elastic element, the first clamping member 111 can be floated on the first base 1100 along the first direction, moving closer to or further away from the first support platform 1101.

By setting a third vertical elastic element, the second clamping member 112 can be floated up and down on the first base 1100. The elastic force of the third vertical elastic element causes the second clamping member 112 to protrude vertically from the first support platform 1101, automatically clamping the second end of the first battery cell 20 on the first support platform 1101. Furthermore, when clamping the second battery cell, the weight of the second battery cell overcomes the elastic force of the first vertical elastic element, pressing the second clamping member 112 down to be flush with the support surface of the first support platform 1101, thus achieving automatic avoidance of the second battery cell. This provides a first clamping assembly 1 with a simple structure and stable and reliable clamping. 1. By setting a fourth vertical elastic element, the third clamping member 121 can be floated up and down on the second base 1200. Then, relying on the elastic force of the fourth vertical elastic element, the third clamping member 121 protrudes vertically from the second support platform 1202 to automatically clamp the first end of the first battery cell 20 on the second support platform 1202. When clamping the second battery cell, the weight of the second battery cell overcomes the elastic force of the fourth vertical elastic element to press the third clamping member 121 down to be flush with the support surface of the second support platform 1202, thus achieving automatic avoidance of the second battery cell. By setting a fourth horizontal elastic element, the fourth clamping member 122 can be floated on the second base 1200 along the first direction, approaching or moving away from the second support platform 1202. Then, relying on the elastic force of the fourth horizontal elastic element, the second end of the battery cell on the second support platform 1202 is automatically clamped. This provides a second clamping assembly 12 with a simple structure and stable and reliable clamping.

[0097] As can be seen, by setting the first clamping member 111 and the second clamping member 112, it is possible to clamp a first battery cell 20 individually through the cooperation of the first clamping member 111 and the second clamping member 112; by setting the third clamping member 121 and the fourth clamping member 122, it is possible to clamp a first battery cell 20 individually through the cooperation of the third clamping member 121 and the fourth clamping member 122; at the same time, it is possible to clamp a second battery cell individually through the cooperation of the first clamping member 111 and the fourth clamping member 122, providing another simple installation structure of the first clamping member 111, the second clamping member 112, the third clamping member 121 and the fourth clamping member 122.

[0098] In one embodiment, the first support member 110 includes a first base 1100, a first support platform 1101, a second lifting member, a fifth vertical elastic member, and a fifth horizontal elastic member, wherein: the first support platform 1101 is fixedly installed on the first base 1100, and the first support platform 1101 is configured to support the first battery cell 20 or the second battery cell; the second lifting member is movably installed on the first base 1100; the second clamping member 112 is slidably installed on the second lifting member along a first direction; the fifth vertical elastic member is vertically disposed between the second lifting member and the first base 1100, and the first end of the fifth vertical elastic member is connected to the first horizontal elastic member. The second lifting member has a fifth vertical elastic member whose second end is connected to the first base 1100. The fifth vertical elastic member is configured to cause the second clamping member 112 to protrude vertically from the first support platform 1101. A fifth horizontal elastic member is horizontally positioned between the second clamping member 112 and the second lifting member. The first end of the fifth horizontal elastic member is connected to the second clamping member 112, and the second end is connected to the second lifting member. The fifth horizontal elastic member is configured to keep the second clamping member 112 close to the first support platform 1101.

[0099] Specifically, the fifth vertical elastic element, the fifth horizontal elastic element, the sixth vertical elastic element, and the sixth horizontal elastic element are all springs.

[0100] Specifically, the second lifting member is slidably mounted on the first base 1100 via a sliding guide pair composed of a guide rail and a slider.

[0101] As can be seen, by setting a fifth vertical elastic element, the second lifting element can be floated up and down on the first base 1100. Then, relying on the elastic force of the fifth vertical elastic element, the second clamping element 112 protrudes vertically from the first support platform 1101. By setting a fifth horizontal elastic element, the second clamping element 112 can be floated on the second lifting element, moving closer to or further away from the first support platform 1101 along the first direction. Then, relying on the elastic force of the fifth horizontal elastic element, the second end of the first battery cell 20 on the first support platform 1101 is automatically clamped. Furthermore, when clamping the second battery cell, the weight of the second battery cell overcomes the elastic force of the fifth vertical elastic element, pressing the second clamping element 112 down to be flush with the support surface of the first support platform 1101, thus achieving automatic avoidance of the second battery cell. This provides a first clamping assembly 11 with a simple structure and stable and reliable clamping. By setting a sixth vertical elastic member, the third clamping member 121 can be floated up and down on the second base 1200. Then, relying on the elastic force of the sixth vertical elastic member, the third clamping member 121 protrudes vertically from the second support platform 1202 to automatically clamp the first end of the first battery cell 20 on the second support platform 1202. When clamping the second battery cell, the weight of the second battery cell overcomes the elastic force of the sixth vertical elastic member to press the third clamping member 121 down to be flush with the support surface of the second support platform 1202, thus achieving automatic avoidance of the second battery cell.

[0102] Please see Figure 2 and Figure 4As shown, in one embodiment, a plurality of sets of elastic limiting members 123 are spaced apart on the bearing surface of the second bearing member 120 along the first direction. Each set of elastic limiting members 123 includes at least one elastic limiting member 123. The first bearing member 110 and the second bearing member 120 are also configured to jointly bear the third battery cell. The third battery cell carried by the first bearing member 110 and the second bearing member 120 presses against the second clamping member 112 and the third clamping member 121, so that the second clamping member 112 and the third clamping member 121 are flush with the bearing surface of the first bearing member 110. The first clamping member 111 abuts against the first end of the third battery cell along the first direction, and the corresponding elastic limiting member 123 abuts against the second end of the third battery cell along the first direction, so as to clamp the third battery cell on the first bearing member 110 and the second bearing member 120.

[0103] In one embodiment, a plurality of sets of elastic limiting members 123 are spaced apart on the bearing surface of the first bearing member 110 along the first direction. Each set of elastic limiting members 123 includes at least one elastic limiting member 123. The first bearing member 110 and the second bearing member 120 are also configured to jointly bear the third battery cell. The third battery cell carried by the first bearing member 110 and the second bearing member 120 presses against the second clamping member 112 and the third clamping member 121, so that the upper surfaces of the second clamping member 112 and the third clamping member 121 are flush with the bearing surface of the first bearing member 110. The corresponding elastic limiting member 123 abuts against the first end of the third battery cell along the first direction, and the fourth clamping member 122 abuts against the second end of the third battery cell along the first direction, so as to clamp the third battery cell on the first bearing member 110 and the second bearing member 120.

[0104] Specifically, each set of elastic limiting members 123 includes a second direction ( Figure 1 Two elastic limiting members 123 are spaced apart in the Y direction, with the first direction and the second direction perpendicular to each other.

[0105] Specifically, the elastic limiting member 123 includes an elastic member and a limiting post. Multiple receiving slots are provided on the bearing surface of the first bearing member 110 or the second bearing member 120. Each receiving slot corresponds to an elastic limiting member 123. The limiting post is installed in the corresponding receiving slot in a way that allows it to be raised and lowered through the elastic member.

[0106] As can be seen, by setting several sets of elastic limiting members 123 on the first carrier 110 or the second carrier 120, any set of elastic limiting members 123 can cooperate with the first clamping member 111 or the fourth clamping member 122 to clamp the third battery cell jointly supported by the first carrier 110 and the second carrier 120, so that the battery cell fixture 10 can be adapted to at least three specifications of battery cells, further improving the versatility of the battery cell fixture.

[0107] In one embodiment, the first clamping assembly 11 further includes a first driving source, and the second clamping assembly 12 further includes a second driving source. The first clamping member 111 is slidably mounted on the first end of the first carrier member 110 along a first direction, and the second clamping member 112 is movably mounted on the second end of the first carrier member 110. The first driving source is used to drive the second clamping member 112 to move vertically up and down. The third clamping member 121 is movably mounted on the first end of the second carrier member 120 and slidably mounted along the first direction. The fourth clamping member 122 is fixedly mounted on the second end of the second carrier member 120. The second driving source is used to drive the third clamping member 121 to move vertically up and down.

[0108] Specifically, both the first and second drive sources can be self-powered motors, conventional motors, or cylinders.

[0109] As can be seen, by setting the first driving source and the second driving source, the second clamping member 112 and the third clamping member 121 are driven to rise and fall, so that when it is necessary to clamp the second battery cell or the third battery cell, the second clamping member 112 and the third clamping member 121 are driven to fall and avoid the second battery cell or the third battery cell. This provides a driving method that uses a power source to drive the second clamping member 112 and the third clamping member 121 to rise and fall.

[0111] 1) It can be adapted to at least two types of battery cells, and has good versatility.

[0112] 2) The first clamping component, the second clamping component, the third clamping component and the fourth clamping component have a simple overall structure and good flexibility, while achieving stable and reliable clamping of the battery cell.

The two sets of unlocking mechanisms 40 are respectively arranged on the sides of the loading station 31 and the unloading station 33. When the conveying mechanism 30 conveys a plurality of battery cell fixtures 10 to the loading station 31, the unlocking mechanism 40 at the loading station 31 is configured to push open the battery cell fixtures 10 on the loading station 31. The first clamping member 111, the second clamping member 112, the third clamping member 121, and the fourth clamping member 122 of the battery cell fixture 10 are used to receive the battery cells to be transported through the battery cell fixture 10.

[0115] Specifically, the conveying mechanism 30 can also be either a plate chain conveyor or a belt conveyor.

[0116] The battery cell conveying line of this application uses a conveying mechanism 30 to sequentially transport several battery cell fixtures 10 to a loading station 31, at least one processing station 32, and a unloading station 33, thereby realizing the automatic flow of several battery cell fixtures 10 and the battery cells held by several battery cell fixtures 10 between the loading station 31, at least one processing station 32, and the unloading station 33. By setting unlocking mechanisms 40 on the loading station 31 and the unloading station 33, the battery cell fixtures 10 are automatically opened at the loading station 31 and the unloading station 33 to facilitate the reception of battery cells and the removal of processed battery cells, thereby improving work efficiency. At the same time, the battery cell fixtures 10 can be adapted to battery cells of different specifications, and have good versatility.

[0117] Please see Figure 1 and Figure 2 As shown, in one embodiment, the unlocking mechanism 40 includes two unlocking components 41. One unlocking component 41 is configured to correspond to the first clamping member 111 or the second clamping member 112 of the first carrier 110, and the other unlocking component 41 is configured to correspond to the third clamping member 121 or the fourth clamping member 122 of the second carrier 120. Each unlocking component 41 includes a first driving member 410 and a first push block 411. The driving end of the first driving member 410 is connected to the first push block 411. 0 is configured to drive the first push block 411 to approach or move away from the first clamping member 111 or the second clamping member 112 corresponding to the unlocking component 41; the first drive member 410 drives the first push block 411 to approach and abut against the first clamping member 111 or the second clamping member 112 corresponding to the unlocking component 41, so as to push the first clamping member 111 and the second clamping member 112 away from each other and / or push the third clamping member 121 and the fourth clamping member 122 away from each other, thereby opening the battery cell fixture 10.

[0118] Specifically, one unlocking component 41 is set to the first clamping component 111 of the first carrier 110, and the other unlocking component 41 is set to the third clamping component 121 of the second carrier 120. The first driving component 410 is a cylinder, and the first push block 411 is set to the side of the corresponding clamping component. The first driving component 410 drives the first push block 411 to reciprocate along the second direction, causing the first push block 411 to move closer to or away from the corresponding clamping component. The second direction is perpendicular to the first direction.

[0119] Specifically, the contact portion between the first push block 411 and the corresponding clamping member is an inclined surface. When the first push block 411 moves along the second direction, it abuts against the corresponding clamping member and drives the corresponding clamping member to move along the first direction. Both the first clamping member 111 and the third clamping member 121 are equipped with rotatable rollers 42. When unlocking, the first push block 411 abuts against the rollers 42 on the corresponding clamping member.

The first driving member 410 drives the first push block 411 to push against the corresponding clamping member, so that the first clamping member 111 and the second clamping member 112 move away from each other and / or push the third clamping member 121 and the fourth clamping member 122 move away from each other, thereby opening the battery cell fixture 10. This provides an unlocking mechanism 40 that is simple in structure and easy to implement; moreover, the first clamping component 11 and the second clamping component 12 can be controlled independently, which is flexible.

The first second push block 46 is disposed corresponding to the first clamping member 111 or the second clamping member 121 of the first carrier member 110, and the second second push block 46 is disposed corresponding to the third clamping member 121 or the fourth clamping member 122 of the second carrier member 120. The track plate 45 is slidably mounted on the base plate 43 along a first direction. The fixed end of the second driving member 44 is mounted on the base plate 43, and the driving end of the second driving member 44 is connected to the track plate 45. The second driving member 44 is configured to drive the track plate 45 to reciprocate along the first direction. The second push blocks 46 are slidably mounted on the base plate 43, and the track plate 45 is slidably mounted along the first direction. Two inclined track grooves 450 are arranged parallel to each other in the direction. Each track groove 450 corresponds to a second push block 46. A roller 42 is installed on the second push block 46 to fit into the corresponding track groove 450. The second drive member 44 drives the track plate 45 to move back and forth in the first direction. Then, through the cooperation of the track groove 450 and the roller 42, the two second push blocks 46 are driven to move up and down and laterally at the same time, so that the two second push blocks 46 move closer or further away from the corresponding clamping member at the same time. The two second push blocks 46 move closer and abut against the corresponding clamping member at the same time, so that the first clamping member 111 and the second clamping member 112 move away from each other and the third clamping member 121 and the fourth clamping member 122 move away from each other, thereby opening the battery cell fixture 10.

[0122] Specifically, the first second push block 46 is set to correspond to the first clamping member 111 of the first carrier 110, the second second push block 46 is set to correspond to the third clamping member 121 of the second carrier 120, the second driving member 44 is an electric cylinder, the track plate 45 is slidably mounted on the base plate 43 along the first direction through a sliding guide pair composed of a guide rail and a slider, and the second push block 46 is slidably mounted on the base plate 43 through a sliding guide pair composed of a guide rail and a slider.

[0123] Specifically, both the first clamping member 111 and the third clamping member 121 are equipped with rotatable rollers 42. When unlocking, the second push block 46 abuts against the rollers 42 on the corresponding clamping member.

[0124] As can be seen, through the cooperation of the second driving member 44, the track plate 45 and the two second push blocks 46, the two second push blocks 46 are driven to approach and abut against the corresponding clamping members, so that the first clamping member 111 and the second clamping member 112 move away from each other and the third clamping member 121 and the fourth clamping member 122 move away from each other, thereby realizing the automatic opening of the battery cell fixture 10; through the cooperation of the two track grooves 450 and the rollers 42 on the two second push blocks 46, the synchronous opening and clamping of the first clamping component 11 and the second clamping component 12 of the battery cell fixture 10 are controlled by a single driving member, providing an unlocking mechanism 40 with high control precision and stable and reliable operation.

[0125] The general working principle of the battery cell delivery line proposed in this application embodiment is as follows:

[0126] 1) The conveying mechanism 30 conveys several battery cell fixtures 10 to the loading station 31.
