Description

Technical Field

[0001] This utility model relates to the field of battery processing, and in particular to a testing device for cylindrical batteries. Background Technology

[0002] Cylindrical lithium-ion batteries are widely used in small digital electronic products, power tools, electric vehicles, and model aircraft due to their advantages such as high energy density, good cycle life, and low environmental pollution. However, in recent years, there have been frequent incidents of cylindrical lithium-ion batteries exploding and injuring people, making the safety of cylindrical lithium-ion batteries extremely important.

[0003] To ensure the safety of lithium-ion batteries, they need to be tested during production and processing, which requires the use of appropriate testing equipment. However, the testing equipment currently available on the market is not convenient for conducting power-on tests on lithium-ion batteries, resulting in unsatisfactory test results and often causing problems. Therefore, a testing device for cylindrical batteries is proposed. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A testing device for cylindrical batteries includes a workbench with a first conveyor belt for carrying and transporting the cylindrical batteries. The first conveyor belt is horizontally positioned on the workbench, and a cylindrical battery entry / exit limiting frame for limiting the entry and exit of the cylindrical batteries is provided on one side of the first conveyor belt. A support platform is provided between the first conveyor belt and the workbench, and the support platform is horizontally positioned on the workbench. A pusher is slidably mounted on the top of the support platform and is horizontally supported by the first conveyor belt. When the pusher moves on the support platform, it pushes the cylindrical batteries at the top of the first conveyor belt into the cylindrical battery entry / exit limiting frame. Test probe moving frames are vertically mounted on both sides of the cylindrical battery entry / exit limiting frame, and test probes are horizontally mounted on the top of each test probe moving frame. The test probe moving frames move along the sides of the cylindrical battery entry / exit limiting frame, and the test probes all horizontally penetrate the sides of the cylindrical battery entry / exit limiting frame. The test probes and the test probe moving frames move in the same direction.

[0006] Preferably, a moving block is provided between the cylindrical battery entry / exit limiting frame and the test probe moving frame, and the moving block is laterally positioned on the side of the first conveyor belt. The moving block and the test probe moving frame move in the same direction and are elastically connected by a spring. A guide rail is provided between the moving block and the first conveyor belt, and the guide rail is laterally located on the side of the first conveyor belt. The moving block and the guide rail are in sliding engagement, and the moving block and the pusher are in driving engagement.

[0007] Preferably, a guide wheel frame and a triangular block are provided between the moving block and the pusher frame. The guide wheel frame is vertically located at the bottom of the moving block, and the triangular blocks are horizontally located on both sides of the bottom surface inside the pusher frame, forming a moving track between the triangular blocks. The guide wheel frame rolls against the side of the triangular blocks, and the triangular blocks and the pusher frame move in the same direction.

[0008] Preferably, a second conveyor belt is provided on the other side of the cylindrical battery entry and exit limiting frame to carry and transport the tested cylindrical batteries, and a receiving box for collecting cylindrical batteries is provided obliquely on one side of the second conveyor belt. A movable baffle is provided laterally inside the cylindrical battery entry and exit limiting frame. The receiving box is formed with multiple receiving slots for collecting cylindrical batteries, and the slot openings of the receiving slots are equipped with full sensors.

[0009] Preferably, a cylinder is provided between the support platform and the pusher, and the cylinder is laterally located on one side of the support platform. The cylinder is driven by the pusher, which moves the pusher on the support platform to push the cylindrical battery on the first conveyor belt into the cylindrical battery entry and exit limit frame. A first sensor and a second sensor are also provided between the support platform and the pusher, and the first sensor and the second sensor are located at the front and rear ends of the support platform, respectively. The first sensor and the second sensor are electrically connected to the cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the pusher moves back and forth on the support platform and pushes the cylindrical battery into the cylindrical battery entry and exit limit frame. During the movement of the pusher, the test probe moving frame, along with the test probe, moves on both sides of the cylindrical battery entry and exit limit frame. For this purpose, the pusher drives the test probe to make contact and conduct with the cylindrical battery inside the cylindrical battery entry and exit limit frame, thereby testing the cylindrical battery. During the test, the pusher stops moving and pushes against the cylindrical battery inside the cylindrical battery entry and exit limit frame. After the test is completed, the pusher moves and resets, driving the test probe moving frame, along with the test probe, to move away from both sides of the cylindrical battery entry and exit limit frame. During the resetting process, the pusher no longer limits the cylindrical battery inside the cylindrical battery entry and exit limit frame, so that the cylindrical battery rolls out of the cylindrical battery entry and exit limit frame for the next new cylindrical battery to be tested.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4In this embodiment of the invention, the testing device for cylindrical batteries includes a workbench 1. The workbench 1 is provided with a first conveyor belt 3 for carrying and transporting the cylindrical batteries. The first conveyor belt 3 is horizontally arranged on the workbench 1, and a cylindrical battery entry / exit limiting frame 5 for limiting the entry and exit of the cylindrical batteries is provided on one side of the first conveyor belt 3. A support platform 10 is provided between the first conveyor belt 3 and the workbench 1, and the support platform 10 is horizontally arranged on the workbench 1. A pusher 11 is slidably arranged at the top of the support platform 10. The material rack 11 is horizontally mounted on the first conveyor belt 3. When the material pusher 11 moves on the support platform 10, it pushes the cylindrical batteries at the top of the first conveyor belt 3 into the cylindrical battery entry / exit limiting frame 5. Test probe moving frames 13 are vertically arranged on both sides of the cylindrical battery entry / exit limiting frame 5, and test probes 14 are horizontally arranged at the top of each test probe moving frame 13. The test probe moving frames 13 move along the sides of the cylindrical battery entry / exit limiting frame 5, and the test probes 14 all horizontally penetrate the sides of the cylindrical battery entry / exit limiting frame 5. The test probe 14 and the test probe moving frame 13 move in the same direction, so that the pusher frame 11 moves back and forth on the support platform 10 and pushes the cylindrical battery into the cylindrical battery entry and exit limit frame 5. During the movement of the pusher frame 11, the test probe moving frame 13 and the test probe 14 move on both sides of the cylindrical battery entry and exit limit frame 5. For this purpose, the pusher frame 11 drives the test probe 14 to make contact with the cylindrical battery inside the cylindrical battery entry and exit limit frame 5, thereby testing the cylindrical battery. During the test, the pusher 11 stops moving and pushes the cylindrical battery into and out of the limiting frame 5. After the test, the pusher 11 moves and resets, driving the test probe moving frame 13 and the test probe 14 to move away from both sides of the cylindrical battery entry and exit limiting frame 5. During the movement and reset of the pusher 11, it no longer limits the cylindrical battery into and out of the limiting frame 5, so that the cylindrical battery rolls out of the limiting frame 5 for the next new cylindrical battery to be tested.

[0020] A movable block 21 is provided between the cylindrical battery entry / exit limiting frame 5 and the test probe moving frame 13. The movable block 21 is laterally positioned on the side of the first conveyor belt 3, and the movable block 21 and the test probe moving frame 13 move in the same direction. A spring (not shown in the figure) is elastically connected between the movable blocks 21. A guide rail 20 is provided between the movable block 21 and the first conveyor belt 3, and the guide rail 20 is laterally located on the side of the first conveyor belt 3. The movable block 21 and the guide rail 20 are in sliding engagement, and the movable block 21 and the pusher frame 11 are in driving engagement. Thus, when the pusher frame 11 moves, it drives the movable block 21 to move along the guide rail 20 on the side of the first conveyor belt 3, which in turn moves the test probe moving frame 13 and the test probe 14 on both sides of the cylindrical battery entry / exit limiting frame 5.

[0021] A guide wheel frame 19 and triangular blocks 18 are provided between the movable block 21 and the pusher frame 11. The guide wheel frame 19 is vertically located at the bottom end of the movable block 21, and the triangular blocks 18 are all horizontally located on both sides of the inner bottom surface of the pusher frame 11, forming a moving track between the triangular blocks 18. The guide wheel frame 19 rolls against the side of the triangular blocks 18, and the triangular blocks 18 and the pusher frame 11 move in the same direction. Thus, when the pusher frame 11 moves on the support platform 10, the triangular blocks 18 are moved along with it. The guide wheel frame 19 is moved and pushed, so that the guide wheel frame 19, together with the moving block 21, drives the test probe moving frame 13, together with the test probe 14, to close in the middle of the cylindrical battery entry and exit limit frame 5, and makes the test probe 14 contact and conduct with the cylindrical battery inside the cylindrical battery entry and exit limit frame 5. When the pusher frame 11 moves and resets, the spring between the moving blocks 21 makes the moving block 21, together with the guide wheel frame 19, the test probe moving frame 13 and the test probe 14 elastically reset.

[0022] On the other side of the cylindrical battery entry / exit limiting frame 5, a second conveyor belt 6 is provided to carry and transport the tested cylindrical batteries. A receiving box 7 for collecting cylindrical batteries is obliquely arranged on one side of the second conveyor belt 6. A movable baffle 12 is laterally arranged inside the cylindrical battery entry / exit limiting frame 5, so that the cylindrical batteries moving into the cylindrical battery entry / exit limiting frame 5 can be limited one by one by the movable baffle 12. The receiving box 7 has multiple receiving slots 8 formed inside to carry and collect cylindrical batteries. The slot opening of the receiving slot 8 is provided with a full sensor 9, so that the full sensor 9 can sense whether the cylindrical batteries collected in the receiving slot 8 are full.

[0023] A cylinder 15 is provided between the support platform 10 and the pusher frame 11. The cylinder 15 is laterally located on one side of the support platform 10 and is driven by the pusher frame 11. The cylinder 15 drives the pusher frame 11 to move on the support platform 10, thereby pushing the cylindrical batteries on the first conveyor belt 3 into the cylindrical battery entry and exit limit frame 5. A first sensor 16 and a second sensor 17 are also provided between the support platform 10 and the pusher frame 11. The first sensor 16 and the second sensor 17 are located at the front and rear ends of the support platform 10, respectively, and are electrically connected to the cylinder 15. The first sensor 16 and the second sensor 17 can sense the position of the pusher frame 11 on the support platform 10, thereby controlling the cylinder 15 to drive the pusher frame 11 to move and push the material.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
