Description

Technical Field

[0001] This utility model relates to the field of testing machines, and in particular to a support-load transfer short-circuit testing machine. Background Technology

[0002] A stacked battery is a lithium-ion battery that repeatedly stacks electrodes and separators layer by layer. After the electrodes and separators are stacked, a short-circuit test is required to ensure the yield rate of the stacked battery. Before the short-circuit test, the stacked battery needs to be transported. The following three methods are commonly used in the market:

[0003] 1. A robotic arm with suction cups is used to pick up, transfer and place the cells of stacked batteries. Because stacked batteries are large and heavy, the separator is easily deformed and wrinkled during the process of the suction cup picking up the stacked batteries, and the electrode sheets are loose and misaligned, which affects the quality of the cells.

[0004] 2. When using a clamping robot to hold both ends of the stacked battery cells, the electrodes of the cells are relatively soft, and the clamping robot can easily deform the clamped parts of the cells. In addition, when the clamping robot places the cells into the testing mechanism, the test tray needs to be hollowed out to avoid the clamping robot holding the cells. As a result, the test tray cannot be made into a one-piece tray. When the cells are pressed during the testing process, the hollowed-out parts of the test tray can easily leave indentations on the stacked battery cells, affecting the quality of the cells.

[0005] 3. A gripping robot is used to grip both sides of the battery. Before gripping the stacked battery, the gripping claws need to extend into the bottom of the stacked battery to support it. The gripping robot cannot directly extend into the test platform. The battery needs to be placed on the transfer platform first, and then pushed into the test platform by the push plate. During the movement of the battery cell, friction with the tray will cause diaphragm wear and electrode misalignment, which will affect the quality of the battery cell.

[0006] To address the aforementioned issues, a support and transfer short-circuit testing machine was developed to avoid interference with the battery cells held by the robotic arm, preventing external forces from causing separator wrinkles, damage, and electrode misalignment. This ensures the integrity of the battery cell's appearance and maintains its quality, improving the reliability and efficiency of handling stacked batteries, increasing the yield of stacked batteries, reducing losses, and lowering costs. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a support-load transfer short-circuit tester.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The support and transfer short-circuit tester includes a support bracket and a test bracket arranged in parallel. The support bracket is connected and installed to the test bracket through a first guide rod, and there is one or more first guide rods. It also includes a translation component, a test support mechanism, and a short-circuit test mechanism. The translation component is installed on the support bracket and is used to drive the test support mechanism to move in and out of the test bracket. The test support mechanism is slidably installed on the support bracket through the translation component and is used to reduce the contact surface of the cell support of the stacked battery to provide overhead support for the two ends of the battery. The short-circuit test mechanism is installed between the test bracket and the support bracket, and it moves up and down along the first guide rod between the test bracket and the support bracket to press the cell to perform a battery short-circuit test.

[0009] By adopting the above-mentioned technical solution, the test support mechanism enables the two ends of the battery cell to be suspended and supported, allowing the two ends of the battery cell to be placed on the test support mechanism to avoid the gripping robot from grabbing the battery cell. This avoids the battery being affected by external forces, causing the separator to wrinkle, be damaged, or the electrode to be misaligned, thus ensuring the integrity of the battery cell's appearance and ensuring the quality of the battery cell. It improves the reliability and efficiency of handling stacked batteries and increases the yield of stacked batteries, giving it the advantages of reducing losses and lowering costs. In this way, it effectively solves the problem that the use of suction cup robots, clamping robots, or gripping robots in the current market will damage the appearance of the battery cell, affecting the quality of the battery cell and reducing the yield of the battery.

The electrode pressure block mounting plate moves up and down relative to the first buffer guide rods via the first buffer guide rods. Electrode pressure blocks for pressing the battery cell tabs are mounted at the bottom of the electrode pressure block mounting plate. The structure and working principle of the second short-circuit test assembly are the same as those of the first short-circuit test assembly.

[0012] The first supporting and lifting assembly includes a guide rail mounting plate, a first linear guide rail mounted on the top of the guide rail mounting plate, and the guide rail mounting plate is longitudinally slidably mounted on a first translational support plate via a second guide rod. A support rod lifting drive device is connected to the bottom of the guide rail mounting plate, and the support rod lifting drive device is mounted on the first translational support plate via the first mounting plate. A second mounting plate is provided on the guide rail mounting plate. The structure and working principle of the second supporting and lifting assembly are the same as those of the first supporting and lifting assembly.

[0013] Specifically, the first overhead assembly includes a first support rod mounting seat that is laterally slidably mounted on a first linear guide rail via a first sliding block. A buffer is provided above the first support rod mounting seat, and the buffer is mounted on the first support rod mounting seat via a buffer mounting seat. A first support rod translation drive device is provided on one side of the first support rod mounting seat. The first support rod translation drive device is connected to the first support rod mounting seat via a first connecting plate. The first support rod translation drive device is mounted on the guide rail mounting plate via a second mounting plate.

[0015] Specifically, the first protective film tensioning assembly includes a second guide rod mounting plate, with a protective film clamping plate above the second guide rod mounting plate. The protective film clamping plate holds one end of the protective film. The protective film clamping plate is longitudinally slidable on the second guide rod mounting plate via a second buffer guide rod. The second buffer guide rod pulls the protective film clamping plate downward, thereby pulling the protective film downward. The structure and working principle of the second protective film tensioning assembly are the same as those of the first protective film tensioning assembly. The first and second protective film tensioning assemblies work together to pull the protective film downward to tension it on the first and second support rods. The second buffer guide rod adopts a structure of a straight guide rod with a compression spring inside.

[0016] Specifically, the translation component includes a first load-bearing moving component, a second translation support plate, and a second load-bearing moving component. The first load-bearing moving component is horizontally installed at the bottom of the first translation support plate and at the top of the second translation support plate.

The controller is a PLC programmable logic controller, and the PLC programmable logic controller can be a programmable logic controller of model XDS-40T-D, but is not limited thereto.

[0018] Compared with existing technologies, the beneficial effects of this utility model are as follows: By designing the structure of the test support mechanism and the translation component separately, the test support mechanism can slide in and out of the test bracket through the translation component. The test support mechanism can support the two ends of the battery cell in the air, allowing the two ends of the battery cell to be placed in the air on the test support mechanism to avoid the gripping robot from grabbing the battery cell. This avoids the battery being affected by external forces, causing the separator to wrinkle, be damaged, or the electrode to be misaligned, thus ensuring the integrity of the battery cell's appearance and ensuring the quality of the battery cell. It effectively solves the problem that various robotic arm structures for handling battery cells on the market will damage the appearance of the battery cell, affecting the quality of the battery cell and reducing the battery yield. At the same time, it also improves the reliability and efficiency of handling stacked batteries and increases the yield of stacked batteries, giving it the advantages of reducing losses and lowering costs.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] Reference Figures 1 to 2 As shown, the short-circuit tester of this utility model includes a support bracket 1 and a test bracket 2 arranged in parallel. The support bracket 1 is connected to the test bracket 2 via a first guide rod 3, and there are more than one first guide rod 3. It also includes a translation component 4, a test support mechanism 5, and a short-circuit test mechanism 6. The translation component 4 is mounted on the support bracket 1 and is used to drive the test support mechanism 5 to move in and out of the test bracket 2. The test support mechanism 5 is slidably mounted on the support bracket 1 via the translation component 4 and is used to reduce the contact surface of the cell support of the stacked battery so as to provide overhead support for the two ends of the battery. The short-circuit test mechanism 6 is installed between the test bracket 2 and the support bracket 1, and moves up and down along the first guide rod 3 between the test bracket 2 and the support bracket 1 to press the cell to perform a battery short-circuit test.

[0034] Reference Figures 3 to 4As shown, the short-circuit testing mechanism 6 includes a test horizontal plate 61. A test pressure plate 62 for pressing and fixing the battery cell on the test support mechanism 5 is installed at the bottom of the test horizontal plate 61. A first short-circuit testing component 63 and a second short-circuit testing component 64 are respectively provided on the outer sides of both ends of the test pressure plate 62. The first short-circuit testing component 63 and the second short-circuit testing component 64 are installed on the test horizontal plate 61. The test horizontal plate 61 is longitudinally slidably installed on the first guide rod 3 of the test bracket 2 through a linear bearing 65. A test horizontal plate lifting drive device 66 is connected to the top of the test horizontal plate 61. The test horizontal plate lifting drive device 66 drives the test horizontal plate 61 to move up and down on the first guide rod 3 of the test bracket 2. The first short-circuit test assembly 63 includes a first guide rod mounting plate 67 mounted on a test cross plate 61. An electrode pressure block mounting plate 68 is provided below the first guide rod mounting plate 67. First buffer guide rods 69 are provided at both ends of the first guide rod mounting plate 67. The lower ends of the two first buffer guide rods 69 are connected and installed to the electrode pressure block mounting plate 68. The electrode pressure block mounting plate 68 moves up and down relative to the first buffer guide rods 69 through the first buffer guide rods 69. An electrode pressure block 60 for pressing the battery cell tabs is installed at the bottom of the electrode pressure block mounting plate 68. The structure and working principle of the second short-circuit test assembly 64 are the same as those of the first short-circuit test assembly 63.

[0035] In this embodiment, the test plate 61 is longitudinally slidably mounted on the first guide rod 3 of the test bracket 2 via a linear bearing 65. The test plate lifting drive device 66 drives the test plate 61 to move downward along the first guide rod 3 of the test bracket 2, so that the test pressure plate 62 mounted at the bottom of the test plate 61 presses against the upper surface of the battery cell to fix the battery cell. At the same time, two short-circuit test components respectively provided on both sides of the test pressure plate 62 press against the tabs at both ends of the battery cell to perform short-circuit testing as the test pressure plate 62 moves downward. The first buffer guide rod 69 adopts a structure of a linear guide rod with a compression spring. The two short-circuit test components press against the tabs at both ends of the battery cell and buffer the tabs, avoiding excessive pressure and deformation of the tabs caused by the electrode pressing block 60, thus ensuring the flatness of the battery cell shape. The test plate lifting drive device 66 is a cylinder.

A second overhead assembly 57 and a fourth overhead assembly 58 are mounted on the second support lifting assembly 54. The first overhead assembly 55 and the second overhead assembly 57 are connected to a first support rod 59. The third overhead assembly 56 and the fourth overhead assembly 58 are connected to a second support rod 50. A protective device is provided above the first support rod 59 and the second support rod 50 to protect the battery cell diaphragm from being scratched. The protective film 501 and the pillow 52 are respectively provided with a first protective film tensioning component 502 and a second protective film tensioning component 503 on both sides. The first protective film tensioning component 502 is installed on the same end of the first support lifting component 53 and the second support lifting component 54, and the second protective film tensioning component 503 is installed on the other end of the first support lifting component 53 and the second support lifting component 54. The first protective film tensioning component 502 and the second protective film tensioning component 503 are respectively connected and installed to the two ends of the protective film 501. The first support rod 59 and the second support rod 50 support the protective film 501. The first protective film tensioning component 502 and the second protective film tensioning component 503 tighten the two ends of the protective film 501 to tension the protective film 501.

[0037] In this embodiment, the first overhead assembly 55 and the third overhead assembly 56 are mounted opposite each other on the first supporting lifting assembly 53, and the second overhead assembly 57 and the fourth overhead assembly 58 are mounted opposite each other on the second supporting lifting assembly 54.

The third overhead assembly 56 and the fourth overhead assembly 58 are connected to the second support rod 50 and jointly push the second support rod 50 to move back and forth. The first support rod 59 and the second support rod 50 move closer to each other or further away from each other. While the first supporting lifting assembly 53 drives the first overhead assembly 55 and the third overhead assembly 56 to rise or fall together, the second supporting lifting assembly 54 drives the second overhead assembly 57 and the fourth overhead assembly 58 to rise or fall together, ultimately achieving simultaneous and synchronous raising or lowering of the first support rod 59 and the second support rod 50. A protective film 501 is disposed on top of the first support rod 59 and the second support rod 50. The protective film 501 isolates the battery cell from the first support rod 59 and the second support rod 50 to prevent the first support rod 59 and the second support rod 50 from scratching the diaphragm at the bottom of the battery cell when they move closer or further apart. The two ends of the protective film 501 disposed on the first support rod 59 and the second support rod 50 are respectively connected to a first protective film tensioning component 502 and a second protective film tensioning component 503. When the first protective film tensioning component 502 and the second protective film tensioning component 503 pull the protective film 501 downward together, the protective film 501 can be tensioned. A support pillow 52 is provided below the first support rod 59 and the second support rod 50. The support pillow 52 is mounted on the first translation support plate 51.

A support rod lifting drive device 532 is connected to the bottom of the guide rail mounting plate 530. The support rod lifting drive device 532 is mounted on the first translational support plate 51 via the first mounting plate 533. A second mounting plate 534 is provided on the guide rail mounting plate 530. The structure and working principle of the second supporting and lifting assembly 54 are the same as those of the first supporting and lifting assembly 53. In this embodiment, the support rod lifting drive device 532 is a cylinder.

[0039] Reference Figures 7 to 8As shown, the first overhead assembly 55 includes a first support rod mounting seat 552 that is laterally slidably mounted on the first linear guide rail 531 via a first slide block 551.

The first support rod translation drive device 555 is connected to the first support rod mounting seat 552 via a first connecting plate 556, and is mounted on the guide rail mounting plate 530 via a second mounting plate 534. The structure and working principle of the second overhead assembly 57 are the same as those of the first overhead assembly 55. The first overhead assembly 55 and the second overhead assembly 57 jointly drive the first support rod 59 to move back and forth. In this embodiment, the first support rod translation drive device 555 is a cylinder.

[0040] Reference Figures 7 to 8 As shown, the third overhead assembly 56 includes a second support rod mounting seat 562 that is laterally slidably mounted on the first linear guide rail 531 via a second slide block 561. A limiting block 563, which cooperates with a buffer 553, is mounted on the top of the second support rod mounting seat 562. A second support rod translation drive device 564 is provided on one side of the second support rod mounting seat 562. The second support rod translation drive device 564 is connected to the second support rod mounting seat 562 via a second connecting plate 565 and is mounted on the guide rail mounting plate 530 via a second mounting plate 534. The structure and working principle of the fourth overhead assembly 58 are the same as those of the third overhead assembly 56. The third overhead assembly 56 and the fourth overhead assembly 58 jointly drive the second support rod 50 to move back and forth. In this embodiment, the second support rod translation drive device 564 is a cylinder.

[0041] Reference Figure 9 As shown, the first protective film tensioning assembly 502 includes a second guide rod mounting plate 5021. A protective film clamping plate 5022 is provided above the second guide rod mounting plate 5021. The protective film clamping plate 5022 clamps one end of the protective film 501. The protective film clamping plate 5022 is longitudinally slidably mounted on the second guide rod mounting plate 5021 through one or more second buffer guide rods 5023. The second buffer guide rods 5023 pull the protective film clamping plate 5022 downward, thereby pulling the protective film 501 downward. The structure and working principle of the second protective film tensioning assembly 503 are the same as those of the first protective film tensioning assembly 502. The first protective film tensioning assembly 502 and the second protective film tensioning assembly 503 work together to pull the protective film 501 downward to tension the protective film 501 on the first support rod 59 and the second support rod 50. The second buffer guide rod 5023 adopts a structure of a straight guide rod with a compression spring.

[0042] In this embodiment, refer to Figures 5 to 9 As shown, the working process of the test support mechanism 5 is as follows: Before the short circuit test, the battery cell is placed on the protective film 501 of the test support mechanism 5 for positioning in preparation for the short circuit test mechanism 6 to press the battery cell: the first support rod 59 and the second support rod 50 approach each other and the first support rod 59 and the second support rod 50 rise synchronously, and the first protective film tensioning component 502 and the second protective film tensioning component 503 pull down to tighten the protective film 501, so that the battery cell is placed on the first support rod 59 and the second support rod 50 through the protective film 501. At this time, the first support rod 59 and the second support rod 50 support the two ends of the battery cell to avoid the robotic gripper scratching the diaphragm on the bottom surface of the battery cell when it withdraws from the gripping of the battery cell. When the first support rod 59 and the second support rod 50 move away from each other and the first support rod 59 and the second support rod 50 lower synchronously, the first protective film tensioning assembly 502 and the second protective film tensioning assembly 503 simultaneously pull the protective film 501 downward to tension the protective film 501, so that the protective film 501 is lowered and laid flat on the support pillow 52. The battery cell is placed stably on the support pillow 52 along with the protective film 501 so that the short circuit test mechanism 6 can press the battery cell to fix it.

[0043] When the battery cell test is completed and it needs to be removed from the test support mechanism 5: the first support rod 59 and the second support rod 50 move closer to each other again and rise synchronously. The first support rod 59 and the second support rod 50 lift the battery cell together. The first protective film tensioning component 502 and the second protective film tensioning component 503 pull the protective film 501 downwards synchronously to tension the protective film 501, so that the protective film 501 can protect the diaphragm on the bottom surface of the battery cell to avoid the first support rod 59 and the second support rod 50 moving closer to each other and scratching the diaphragm on the bottom surface of the battery cell. The two ends of the battery cell are suspended, so that the bottom of the two ends of the battery cell are exposed. The two ends of the battery cell are supported by a gripping robot arm, which avoids the problem that when the traditional robot arm gripper is used to transport the battery cell, it is inserted between the battery cell and the support plate, which can easily puncture the diaphragm on the bottom surface of the battery cell and cause damage to the appearance of the battery cell.

[0044] Reference Figures 10 to 11 As shown, the translation component 4 includes a first load-bearing moving component 41, a second translation support plate 42, and a second load-bearing moving component 43. The first load-bearing moving component 41 is horizontally installed at the bottom of the first translation support plate 51 and at the top of the second translation support plate 42. The second load-bearing moving component 43 is horizontally installed at the bottom of the second translation support plate 42 and is mounted on the load-bearing bracket 1.

[0045] Reference Figures 10 to 11As shown, the first supporting moving assembly 41 includes at least two second linear guide rails 411 mounted on the top of the second translational support plate 42 and a first pallet translation drive device 412 mounted on the bottom of the first translational support plate 41. The first pallet translation drive device 412 is driven to the second translational support plate 42. In this embodiment, the first pallet translation drive device 412 is a cylinder, but it is not a limitation.

[0046] Reference Figures 10 to 11 As shown, the second carrier moving assembly 43 includes at least two third linear guide rails 431 mounted on the top of the carrier bracket 1 and a second pallet translation drive device 432 mounted on the bottom of the second translation support plate 42. The second pallet translation drive device 432 is connected to the carrier bracket 1. The first carrier moving assembly 41 and the second carrier moving assembly 43 sequentially move the test support mechanism 5 out of the test bracket 2 to receive the battery cell to be tested or to deliver the battery cell after testing. The structural design of the translation assembly 4 enables long-distance reception or delivery of battery cells. In this embodiment, the second pallet translation drive device 432 is a cylinder, but it is not a limitation.

[0047] Reference Figures 1 to 11 As shown, during operation, the translation component 4 of the short-circuit tester drives the test support mechanism 5 to move out of the test bracket 2 to receive the battery cell to be tested or to deliver the battery cell that has been tested. The test support mechanism 5 can reduce the contact surface of the battery cell support for the stacked battery to expose the bottom surfaces of both ends of the battery. When the battery cell is placed on the test support mechanism 5, the test support mechanism 5 suspends the two ends of the battery (i.e., the test support mechanism 5 suspends the two ends of the battery). When the translation component 4 drives the test support mechanism 5 to move into the test bracket 2, the short-circuit test mechanism 6 lowers and presses the battery cell to perform a short-circuit test on the battery cell. After the short-circuit test of the battery cell is completed, the short-circuit test mechanism 6 rises and resets to exit the short-circuit test of the battery cell. The translation component 4 drives the test support mechanism 5 to move out of the test bracket 2 to wait for the battery cell removal mechanism to remove the battery cell that has completed the short-circuit test. The test support mechanism 5 adopts a support structure that suspends the two ends of the battery cell to allow the battery cell removal mechanism to clear the way. Its overall structural design enables it to avoid interference with the cell handling mechanism (such as a gripping robot) when handling the cells, thus preventing the battery from being affected by external forces, which could cause diaphragm wrinkles, damage, or electrode misalignment. This ensures the integrity of the cell's appearance and guarantees its quality. It also improves the reliability and efficiency of handling stacked batteries and increases the yield of stacked batteries. It effectively solves the problem that the use of suction cup robots, clamping robots, or gripping robots on the market all cause varying degrees of damage to the cell's appearance during cell handling, thus affecting cell quality and reducing battery yield.
