Description

Technical Field

[0001] This invention relates to the field of battery manufacturing, and in particular to a battery production equipment. Background Technology

[0002] In existing technologies, battery production mainly includes the following processes: first, manufacturing the battery casing, typically formed by stamping aluminum-plastic film; then, assembling the battery cells into the casing; next, folding the casing to enclose the cells; hot-pressing the top and sides of the casing; and finally, conducting electrical tests on the battery. In existing technologies, the manufacturing of the battery casing, battery assembly, and battery testing are completed through battery casing production equipment, final assembly equipment, and testing and unloading equipment, respectively. Currently, battery production quality remains insufficient; the quality upon reaching the testing equipment is not consistently stable, affecting the quality of the finished product. Furthermore, in current battery production, the production of battery casings, battery assembly, and battery testing are decentralized processes, requiring semi-finished products to circulate between workshops, impacting production efficiency. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a battery production equipment that can improve the production quality of batteries, while also exhibiting high equipment integration, which is beneficial for improving production efficiency.

[0004] According to an embodiment of the present invention, a battery manufacturing apparatus includes: a battery casing manufacturing device for producing battery casings; and an assembly device for receiving the battery casings produced by the battery casing manufacturing device, installing battery cells into the battery casings, and then encapsulating them to form a battery. The assembly device includes a battery cell mounting mechanism, a battery casing folding mechanism, a top sealing mechanism, and a side sealing mechanism. The battery cell mounting mechanism is used to install the battery cells into the battery casings. The battery casing folding mechanism is used to fold the battery casings to enclose the battery cells and form the battery. The top sealing mechanism is used to seal the top edge of the folded battery casings, and the side sealing mechanism is used to seal the sides of the top-sealed battery casings. The test and discharge device is used to receive the battery assembled by the final assembly device, test the battery, and then send it out. The test and discharge device includes a testing mechanism and a discharge mechanism. The testing mechanism is used to test the battery, and the discharge mechanism is used to send out the tested battery. The test and discharge device also includes a resealing mechanism and a side clamping and shaping mechanism. The resealing mechanism is used to perform secondary edge sealing on the battery casing, and the side clamping and shaping mechanism is used to clamp and shape the battery after secondary edge sealing. The side sealing mechanism, the resealing mechanism, the side clamping and shaping mechanism, and the testing mechanism are arranged sequentially adjacent to each other.

[0005] According to an embodiment of the present invention, a battery production equipment has at least the following beneficial effects: By adding a resealing mechanism and a side-clamping and shaping mechanism before the testing mechanism and after the side-sealing mechanism of the assembly unit, the battery's edge sealing effect can be strengthened a second time. Simultaneously, clamping and shaping are performed immediately after the second resealing, resulting in a more regular battery shape, facilitating testing by the testing mechanism and improving the final product quality. Furthermore, this battery production equipment integrates the battery casing production device, the assembly unit, and the testing and unloading device, thereby improving equipment integration and centralizing the production process. This reduces the transfer of semi-finished products between workshops, improving production efficiency.

The flipping seat is rotatably disposed on the turntable and can be unfolded and folded relative to the battery case loading seat. The flipping driver is disposed on the turntable and connected to the flipping seat. The flipping driver is used to drive the flipping seat to rotate. The flipping seat and the battery case loading seat are provided with battery case fixing structures for fixing the two halves of the battery case.

[0012] According to some embodiments of the present invention, the side clamping and shaping mechanism includes a connecting seat, a connecting seat driver, a left clamping block, a right clamping block, a top clamping block, and a clamping block linkage drive structure. The connecting seat can approach and move away from the battery entering the corresponding workstation of the side clamping and shaping mechanism. The connecting seat driver is used to drive the connecting seat to move. The left clamping block, the right clamping block, and the top clamping block are disposed on the connecting seat and surround to form a battery clamping position. The clamping block linkage drive structure is connected to the left clamping block, the right clamping block, and the top clamping block and is used to drive the three to approach and move away from each other synchronously.

[0013] According to some embodiments of the present invention, the clamping block linkage drive structure includes a linkage seat, a left connecting rod, a right connecting rod, and a front and rear linear actuator. The left clamping block and the right clamping block are slidably disposed on the connecting seat, and the linkage seat is slidably disposed on the connecting seat.

[0022] Reference Figures 1 to 7 A battery manufacturing apparatus includes: a battery casing production device 100, an assembly device 200, and a testing and unloading device 300. The battery casing production device 100 is used to produce battery casings 1. The assembly device 200 is used to receive the battery casings 1 produced by the battery casing production device 100, install battery cells 2 onto the battery casings 1, and then encapsulate them to form a battery 3. The assembly device 200 includes a battery cell mounting mechanism 210, a battery casing folding mechanism 220, a top sealing mechanism 230, and a side sealing mechanism 240. The battery cell mounting mechanism 210 is used to install the battery cells 2 onto the battery casings 1. The battery casing folding mechanism 220 is used to fold the battery casings 1 to enclose the battery cells 2 to form the battery 3. The top sealing mechanism 230 is used to seal the top edge of the folded battery casings 1, and the side sealing mechanism 240 is used to seal the sides of the top-sealed battery casings 1. The test discharge device 300 is used to receive the battery 3 assembled by the final assembly device 200, test the battery 3, and then send it out. The test discharge device 300 includes a test mechanism 310 and a discharge mechanism 320. The test mechanism 310 is used to test the battery 3, and the discharge mechanism 320 is used to send out the tested battery 3. The test discharge device 300 also includes a resealing mechanism 330 and a side clamping and shaping mechanism 340. The resealing mechanism 330 is used to perform secondary edge sealing on the battery casing 1 of the battery 3, and the side clamping and shaping mechanism 340 is used to clamp and shape the battery 3 after secondary edge sealing. The side sealing mechanism 240, the resealing mechanism 330, the side clamping and shaping mechanism 340, and the test mechanism 310 are arranged sequentially adjacent to each other.

[0023] The aforementioned battery production equipment, by adding a resealing mechanism 330 and a side clamping and shaping mechanism 340 before the testing mechanism 310 and after the side sealing mechanism 240 of the assembly unit 200, can further enhance the sealing effect of the battery 3. Simultaneously, clamping and shaping are performed immediately after the secondary resealing, making the shape of the battery 3 more regular, facilitating testing by the testing mechanism 310 and improving the final product quality. Furthermore, this battery production equipment integrates the battery casing production device 100, the assembly unit 200, and the testing and unloading device 300, thereby improving equipment integration and centralizing the production process. This reduces the transfer of semi-finished products between workshops, improving production efficiency.

[0024] In this embodiment, both the side sealing mechanism 240 and the resealing mechanism 330 include a heat sealing head and a heat sealing head driver. The heat sealing head is equipped with a heating structure, and the heat sealing head driver is used to drive the heat sealing head to approach and move away from the battery casing 1 of the battery 3. When the battery 3 that needs to be sealed reaches the corresponding work station of the mechanism, the heat sealing head is driven to approach and contact the battery casing 1 to achieve heat sealing. In this embodiment, the heat sealing heads can be arranged in pairs, and the heat sealing head driver is used to drive the paired heat sealing heads to engage and disengage with each other, thereby performing heat sealing by clamping the battery 3 at the part that needs to be sealed. In this embodiment, the heating structure can be a heating liquid circuit or a heating pipe, and the heat sealing head driver can be a cylinder or an electric push rod. In this embodiment, the resealing mechanism 330 performs secondary sealing on the side of the battery casing 1. In other embodiments, the top and side of the battery casing 1 can also be sealed together. In the description of the embodiments, top sealing is performed on the end of the battery casing 1 in the length direction, and side sealing is performed on one side of the battery casing 1 in the width direction.

[0025] In this embodiment, the battery casing production apparatus 100 includes an unwinding mechanism 110, a stamping mechanism 120, a cutting mechanism 130, and a casing-upper robot 140. The unwinding mechanism 110, stamping mechanism 120, cutting mechanism 130, and casing-upper robot 140 are arranged sequentially along a straight line. The unwinding mechanism 110 is equipped with an unwinder 111. The stamping mechanism 120 is equipped with a stamping die 121 and a stamping driver 122. The stamping driver 122 is used to drive the stamping die 121 to open and close. The cutting mechanism 130... The assembly includes a slitting blade 131, a slitting blade driver 132, a slitting support 133, and a film-grabbing robot 134. The slitting blade driver 132 drives the slitting blade 131. The film-grabbing robot 134 is located on the side of the slitting blade 131 away from the stamping mechanism 120 and can move in directions towards and away from the stamping mechanism 120. The slitting support 133 is located between the slitting blade 131 and the film-grabbing robot 134. The upper shell robot 140 is used to transfer the slitting battery casing 1 to the assembly unit 200. Before the production of the battery casing 1, the aluminum-plastic film roll is installed on the unwinder 111 for unwinding. The aluminum-plastic film passes through the stamping die 121 of the stamping mechanism 120, the slitting blade 131 of the slitting mechanism 130, and is finally grasped by the film-grabbing robot 134 of the slitting mechanism 130. During the production of battery casing 1, a stamping die 121 stamps cavities for mounting the battery cells 2 onto the aluminum-plastic film. A film-gripping robot 134 moves the aluminum-plastic film one station, and the stamping die 121 continues to stamp cavities sequentially onto the aluminum-plastic film. Simultaneously, a slitting blade 131 and a slitting blade driver 132 slit the aluminum-plastic film, now with stamped cavities, onto the slitting support 133 of the slitting mechanism 130, forming individual battery casings 1. Finally, a shell-mounting robot 140 transfers the battery casing 1 to the final assembly unit 200. After each battery casing 1 is slit, the film-gripping robot 134 re-grips the aluminum-plastic film and pulls it past the slitting support 133 of the slitting mechanism 130 for re-slitting. Repeating this process allows for the continuous production of individual battery casings 1. The battery casing production device 100 described above has a simple structure, can continuously and uninterruptedly produce battery casings 1, and has high production efficiency.

[0026] It is conceivable that in other embodiments, the battery casing production apparatus 100 is not limited to the structure described above. In the art, there are many other implementations of the apparatus and equipment for the specific production of the battery casing 1, and those skilled in the art can configure it according to the actual situation.

[0027] In this embodiment, the battery casing production apparatus 100 further includes a dust removal mechanism 150, which is disposed between the stamping mechanism 120 and the cutting mechanism 130. This dust removal mechanism can remove the residue generated after stamping of the aluminum-plastic film and the dust adhering to the aluminum-plastic film, thereby ensuring the quality of the product.

[0028] In one embodiment, the dust removal mechanism 150 may include an adsorption hood with an open adsorption chamber facing the aluminum-plastic film. The adsorption hood is connected to a vacuum adsorption pipe for adsorption. In some embodiments, an air-blowing structure may also be used for dust removal, and the specific configuration can be adjusted according to actual conditions.

[0029] In one embodiment, the unwinder 111 may include a rotating roller and a motor. The rotating roller is used to mount the roll material, and the motor is connected to the rotating roller and used to drive its rotation, thereby achieving unwinding. In other embodiments, the roll material can also be unwound by providing traction rollers. It is understood that there are many other implementations in the art for achieving unwinding of roll material, which will not be described in detail here.

[0030] In an embodiment, the stamping die 121 may include an upper die and a lower die, with corresponding cavities and cores provided on the upper and lower dies. The stamping driver 122 may use a cylinder, electric push rod, or the like to drive the upper and lower dies to open and close the die.

[0031] In this embodiment, two slitting blades 131 can be provided, one above the other. The slitting blade driver 132 can be driven by a cylinder or an electric push rod. The aluminum-plastic film is slitting is achieved by the interaction of the two slitting blades 131.

[0032] In this embodiment, the film-grabbing robot 134 uses a linear actuator, such as a cylinder or linear motor, and a cylinder finger on the linear actuator to grasp and move the aluminum-plastic film.

[0033] In this embodiment, the assembly device 200 includes a turntable 250 and a turntable driver for driving the turntable 250 to rotate. A plurality of battery case loading seats 260 are provided on the turntable 250. The battery case folding mechanism 220 is provided in a one-to-one correspondence with the battery case loading seats 260. The battery case loading seats 260 are evenly arranged along the circumference of the turntable 250. The battery case production device 100 includes an upper shell robot 140 for transferring the battery case 1 to the battery case loading seat 260 on the turntable 250. The test discharge device 300 includes a lower battery robot 350 for grabbing the battery 3 from the battery case loading seat 260 on the turntable 250. The upper shell robot 140, the cell loading mechanism 210, the top sealing mechanism 230, the side sealing mechanism 240, and the lower battery robot 350 are arranged sequentially around the turntable 250. When assembling battery 3, the produced battery casing 1 is placed onto the battery casing loading seat 260 by the upper casing robot 140. The turntable driver drives the turntable 250 to rotate, so that the battery casing loading seat 260 containing the battery casing 1 moves to the corresponding station of the cell loading mechanism 210 to perform the cell loading step. Then, the battery casing 1 is folded in half by the battery casing folding mechanism 220 to contain the cell 2. Next, the turntable 250 continues to rotate the assembly of cell 2 and battery casing 1 to the stations corresponding to the top sealing mechanism 230 and the side sealing mechanism 240, and the top sealing and side sealing processes are completed in sequence. Finally, the battery 3 is transferred to the test discharge device 300 by the lower battery robot 350.

[0034] In an embodiment, the turntable driver may be a combination of a motor and a divider, or other structures capable of driving the turntable 250 to rotate.

[0035] In this embodiment, the assembly device 200 further includes a compaction and shaping mechanism 270. The compaction and shaping mechanism 270 is located on the outer periphery of the turntable 250 and adjacent to the upper shell robot arm 140. The compaction and shaping mechanism 270 is used to press the battery case 1 against the battery case loading seat 260. By providing the compaction and shaping mechanism 270, after the upper shell robot arm 140 places the battery case 1 onto the battery case loading seat 260, the compaction and shaping mechanism 270 presses the battery case 1 against the battery case loading seat 260, thereby positioning the battery case 1 on the battery case loading seat 260 and completing the shaping process through cooperation with the battery case loading seat 260. This configuration improves the external shape quality of the battery case 1.

[0036] In this embodiment, the compaction and shaping mechanism 270 includes a compaction plate and a compaction plate driver. The compaction plate is connected to the compaction plate driver and faces the battery case mounting seat 260 on the turntable 250. The compaction plate driver is used to drive the compaction plate toward and away from the battery case mounting seat 260. When the turntable 250 moves the battery case mounting seat 260 containing the battery case 1 to the corresponding station of the compaction and shaping mechanism 270, the compaction plate driver drives the compaction plate to move toward the battery case 1, pressing the battery case 1 against the battery case mounting seat 260, thus completing the compaction and shaping step. In this embodiment, the compaction plate driver can be a cylinder or an electric push rod, etc.

[0037] In this embodiment, the assembly device 200 further includes a top edge trimming mechanism 280, which is located on the outer periphery of the turntable 250 and on the side of the cell assembly mechanism 210 away from the top sealing mechanism 230. The top edge trimming mechanism 280 is used to trim the top edge of the battery case 1. By providing the top edge trimming mechanism 280, the top edge of the battery case 1 can be trimmed before the cell 2 is installed, thereby improving the quality of the product.

[0038] In this embodiment, the top edge trimming mechanism 280 may include a top edge cutter and a top edge cutter driver. Two top edge cutters may be provided, positioned vertically, and driven by the cutter driver to cut against each other, thereby achieving the trimming function. In this embodiment, the cutter driver may be a cylinder or an electric push rod, etc. In this embodiment, the battery casing 1 can be folded in half using the battery casing folding mechanism 220 before top edge trimming, resulting in good trimming quality. After trimming, the battery casing 1 can be opened for assembling the battery cell 2.

[0039] In this embodiment, the battery case folding mechanism 220 includes a flipping base 221 and a flipping driver 222. The flipping base 221 is rotatably mounted on the turntable 250 and can be unfolded and folded relative to the battery case loading seat 260. The flipping driver 222 is mounted on the turntable 250 and connected to the flipping base 221. The flipping driver 222 is used to drive the flipping base 221 to rotate. The flipping base 221 and the battery case loading seat 260 are provided with battery case fixing structures for fixing the two halves of the battery case 1. When receiving the battery case 1, the flipping base 221 is first unfolded relative to the battery case loading seat 260. The upper shell robot 140 places the battery case 1 flat on the flipping base 221 and the battery case loading seat 260. The flipping base 221 and the battery case loading seat 260 fix the two halves of the battery case 1 respectively through the battery case fixing structures. When it is necessary to fold the battery case 1, the flipping base 221 is driven to rotate and overlap onto the upper side of the battery case loading seat 260 by the flipping driver 222, thereby folding the battery case 1 in half.

[0040] In one embodiment, the flipping actuator 222 includes a cylinder, a rack, and a gear. The gear and the rotation axis of the flipping seat 221 are coaxial and fixed to the flipping seat 221. The piston rod of the cylinder is connected to the rack, and the rack and gear mesh. When the cylinder drives the rack to reciprocate, it can drive the gear to rotate in both directions, thereby causing the flipping seat 221 to move. In other embodiments, the flipping actuator 222 is not limited to the above-described structure; for example, a motor can be used to directly drive the flipping seat 221 to rotate.

[0041] In this embodiment, the battery casing fixing structure specifically adopts a vacuum adsorption structure. Vacuum adsorption holes are provided in the flipping seat 221 and the battery casing loading seat 260. These holes generate negative pressure through a negative pressure device, thereby adsorbing and fixing the battery casing 1. In some embodiments, the battery casing fixing structure can also be other structures, such as a pressure clamp, etc.

[0042] In this embodiment, the cell loading mechanism 210 specifically includes a cell conveyor and a cell gripping and placing robot. The cell conveyor is used to input the cell 2, and the cell gripping and placing robot is used to grip the cell 2 on the cell conveyor and install it into the battery casing 1. It is conceivable that in other embodiments, the cell loading mechanism 210 is not limited to the structure described above. In the art, there are many ways to implement the installation of the cell 2, and those skilled in the art can configure it according to the actual situation.

[0043] In this embodiment, the side clamping and shaping mechanism 340 includes a connecting seat 341, a connecting seat driver 342, a left clamping block 343, a right clamping block 344, a top clamping block 345, and a clamping block linkage drive structure. The connecting seat 341 can approach and move away from the battery 3 that enters the corresponding work position of the side clamping and shaping mechanism 340. The connecting seat driver 342 is used to drive the connecting seat 341 to move. The left clamping block 343, the right clamping block 344, and the top clamping block 345 are disposed on the connecting seat 341 and surround to form a battery clamping position. The clamping block linkage drive structure is connected to the left clamping block 343, the right clamping block 344, and the top clamping block 345 and is used to drive the three to approach and move away from each other synchronously. When the test discharge device 300 receives the battery 3 and the battery 3 enters the station corresponding to the side clamping and shaping mechanism 340, the connecting seat driver 342 drives the connecting seat 341 to approach the battery 3, so that the battery 3 enters the battery clamping position. Then, the clamping block linkage drive structure drives the left clamping block 343, the right clamping block 344, and the top clamping block 345 to approach each other, thereby clamping and pressing the periphery of the battery 3 to complete the shaping. The aforementioned side clamping and shaping mechanism 340, through the clamping block linkage drive structure, can simultaneously clamp and shape the top side and both sides of the battery 3, resulting in good shaping effect and requiring fewer drivers.

[0044] In the embodiment shown in the accompanying drawings, the clamping surfaces of the left clamping block 343, right clamping block 344, and top clamping block 345 corresponding to the battery 3 are parallel to the side end faces of the corresponding sides of the battery 3. In some embodiments, in order to improve the quality of clamping and shaping and avoid hollow areas or wrinkles in the battery casing 1, the following structure (not shown in the accompanying drawings) can be preferably adopted: the connecting seat 341 is also provided with a pressing and fixing structure for pressing and fixing the battery 3. The left clamping block 343, right clamping block 344, and top clamping block 345 each include a clamping block base, a clamping plate, and an elastic element. The clamping block linkage drive structure is connected to each clamping block base and is used for driving. When the clamping block base moves, the clamping plate is used to contact the side of the battery 3. One end of the clamping plate is pivotally connected to the clamping block base. When the left clamping block 343, right clamping block 344, and top clamping block 345 are not clamping the battery 3, the clamping plate is in an inclined position relative to the clamping block base: the clamping plate is inclined relative to the corresponding side of the battery 3 and the other end of the clamping plate is closer to the battery 3 than the other end. After the clamping plate comes into contact with the corresponding side of the battery 3, the clamping plate rotates to a position parallel to the corresponding side of the battery 3 and is limited by the clamping block base. An elastic element is provided between the clamping plate and the clamping block base to make the clamping plate tend to be in an inclined position. When clamping and shaping the battery 3, the connecting seat 341 is driven to approach the battery 3 by the connecting seat driver 342. The connecting seat 341 presses against the battery 3 through the pressing and fixing structure, thus fixing the battery 3. Then, the clamping block linkage drive structure drives the left clamping block 343, the right clamping block 344, and the top clamping block 345 to approach each other. The other end of the clamping plate first contacts the battery 3, gradually rotates and switches to a parallel position, thus completely fitting with the corresponding side of the battery 3, completing the clamping and shaping process. Since the clamping plate presses against the corresponding side of the battery 3 from one end, it can gradually flatten the corresponding side of the battery shell 1. At the same time, the elastic force of the elastic element can gradually apply pressure to the corresponding side of the battery shell 1, avoiding the problems of hollowness or wrinkles that are easily caused by direct rigid flattening, thereby further improving the production quality of the battery 3. In the above embodiment, the pressing and fixing structure can be a pressure plate, which can be set to elastically extend and retract, thereby elastically pressing and fixing the battery 3 and reducing damage. In the above embodiment, the elastic element can be a spring or other structure that can provide elastic force.

[0045] In this embodiment, the clamping block linkage drive structure includes a linkage seat 346, a left connecting rod 347, a right connecting rod 348, and front and rear linear actuators. The left clamping block 343 and the right clamping block 344 are slidably disposed on the connecting seat 341, and the linkage seat 346 is slidably disposed on the connecting seat 341. The front and rear linear actuators are disposed on the connecting seat 341 and are used to drive the linkage seat 346 to move back and forth. The top clamping block 345 is fixed to the linkage seat 346 through the connecting rod portion 349. One end of the left connecting rod 347 and the right connecting rod 348 are coaxially hinged to the linkage seat 346. The other end of the left connecting rod 347 is hinged to the left clamping block 343, and the other end of the right connecting rod 348 is hinged to the right clamping block 344. When the battery 3 is clamped by the left clamping block 343, the right clamping block 344, and the top clamping block 345, the left connecting rod 347 and the right connecting rod 348 are arranged in a V-shape. The connecting rod 349 extends along the front-back direction through the angle formed by the left connecting rod 347 and the right connecting rod 348 and extends away from the angle. When the front and rear linear actuators drive the linkage seat 346 to move back and forth, the angle between the left connecting rod 347 and the right connecting rod 348 increases, and the connecting rod 349 moves along the direction of the linkage seat 346. This causes the left clamping block 343 and the right clamping block 344 to move away from each other, and the top clamping block 345 to move away from the position between the left clamping block 343 and the right clamping block 344 along the front-back direction, thereby releasing the battery 3. The above-described clamping block linkage drive structure uses the change in the angle between the left connecting rod 347 and the right connecting rod 348 to synchronize the movement of the clamping blocks. The structure is simple, and the operation is fast and stable.

[0046] In this embodiment, the connector 341 can be slidably mounted on the frame via a guide rod. The battery 3 enters the side clamping and shaping mechanism 340 from below. The connector driver 342 uses a cylinder or an electric push rod to drive the connector 341 to move up and down, thereby moving it closer to and away from the battery 3. In this embodiment, the front and rear linear drivers can be cylinders or electric push rods.

[0047] It is conceivable that in some embodiments, the clamping block linkage drive structure can also adopt other structures, such as three independent drivers, such as cylinders, electric push rods, etc., to drive the left clamping block 343, the right clamping block 344 and the top clamping block 345 to move independently respectively.

[0048] In this embodiment, the test discharge device 300 further includes a tab cutting mechanism 360, which is disposed between the test mechanism 310 and the discharge mechanism 320. By providing the tab cutting mechanism 360, the tabs of the battery 3 can be cut as needed.

[0049] In an embodiment, the test discharge device 300 includes a test transfer mechanism 370 for transferring the battery 3, a sealing mechanism 330, a side clamping and shaping mechanism 340, a test mechanism 310, a tab cutting mechanism 360, a discharge mechanism 320, and a battery lowering robot 350, which are arranged corresponding to the test transfer mechanism 370. The test transfer mechanism 370 is used to sequentially transfer the battery 3 to each mechanism.

[0050] In this embodiment, the test transfer mechanism 370 includes a guide rail that extends linearly. A battery carrier is mounted on the guide rail, which slides along the rail and carries the battery 3. The battery carrier is driven by a carrier drive structure to move along the guide rail and transfer to various mechanisms to perform corresponding processes. The battery carrier drive structure may be, for example, a linear motor. The mover of the linear motor is connected to a carrier linkage. The carrier linkage and the battery carrier can be engaged and disengaged. When a battery carrier needs to be driven to move, the carrier linkage and the battery carrier are engaged, and then the linear motor drives the movement. Once in position, the carrier linkage and the battery carrier are disengaged. The engagement and disengagement structure can be a snap-fit ​​structure: the carrier linkage is provided with a retractable snap-fit ​​part, which engages and disengages with the battery carrier to achieve engagement and disengagement. It is conceivable that the test transfer mechanism 370 can also use other structures, such as a turntable mechanism, depending on the actual situation.

[0051] In this embodiment, the discharge mechanism 320 includes a discharge conveyor 321 and a discharge robot 322. The discharge robot 322 is used to pick up batteries 3 that have completed testing or have undergone testing and tab cutting from the test transfer mechanism 370 and place them on the discharge conveyor 321 for external delivery.

[0052] In this embodiment, the testing mechanism 310 includes an upper and lower pressing structure and an electrode electrical connection structure. The upper and lower pressing structure includes a pressing block that moves up and down driven by a driver, used to press the battery 3. The electrode electrical connection structure includes electrodes that can extend and retract, driven by a driver. When the battery 3 arrives at the testing mechanism 310, it is pressed against the testing transfer mechanism 370 by the pressing block, and the electrodes extend out to contact the electrodes of the battery 3. The electrodes are connected to the testing instrument, thereby enabling testing. After the test is completed, the electrodes and the pressing block are reset, and the battery 3 can be freely transferred.

[0053] In the embodiments, the various robotic arms used for transferring battery casing 1, battery cell 2, or battery 3 can be, depending on the actual situation, either robotic arms with suction cups or robotic arms with grippers. The robotic arms can be equipped with multi-axis motion platforms or robotic arms to drive the suction cups or grippers. It is understood that robotic arms for transferring parts are a conventional technique in this field, and those skilled in the art can configure them according to the actual situation.

[0054] In the embodiments, unless otherwise specified, various actuators for driving components to move in a predetermined direction may specifically be cylinders or electric push rods.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
