Description

Technical Field

[0001] This application relates to the field of storage battery production technology, specifically to a plate testing device for storage battery production. Background Technology

[0002] Testing the plates is a crucial step in the battery production process, ensuring the battery's performance, safety, and reliability.

[0003] A search revealed a patent with publication number CN212254526U, which discloses a lead-acid battery plate testing device. The device includes a base plate with vertically fixed columns on all four sides of its upper surface. The upper surfaces of these columns are fixed to a top plate. Support plates are symmetrically fixed on the left and right sides above the base plate. The columns pass through the corresponding support plates and are slidably connected to them. Two support springs are fixed between each support plate and the base plate, with the columns passing through the springs at their respective positions. Multiple slide rails are also fixed to the two support plates. Slide plates are fixed above each support plate and are slidably connected to the corresponding slide rails. Multiple finger cylinders are fixed to each of the two slide plates. Support rods are symmetrically fixed on the front and rear sides between the two support plates. A pressure plate, through which the columns pass and slidably connect to the top plate, is also fixed between the two support plates. This device can accurately test the impact resistance of the battery plates.

[0004] The above method involves pressing and impacting the electrode plate with a pressure plate. However, when the pressure plate is used alone to impact the electrode plate, the main damage is compression and impact damage. This type of damage is relatively simple and may not reflect the various damage conditions that the electrode plate suffers in actual use. This results in a relatively simple test and limited test effect. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a plate testing device for battery production, so as to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a plate testing device for battery production, including a device platform. A horizontal plate is fixedly connected to the inner side of the device platform, and a shifting rod is movably inserted through the inner side of the horizontal plate. A collision block is fixedly connected to the bottom of the shifting rod, and a spring is fixedly sleeved on the outer surface of the shifting rod. An L-shaped plate is fixedly connected to the top of the shifting rod, and a cutter is provided at the bottom of the L-shaped plate. A driving mechanism is provided on the device platform, and a limit clamping mechanism is provided on the device platform.

[0007] Preferably, the driving mechanism includes a motor fixedly installed inside the device platform. The output end of the motor is fixedly connected to a drive gear. The driving mechanism can drive the rotating shaft to rotate, thereby causing the two sets of collision blocks and the cutter to synchronously and periodically squeeze and collide with the battery plates through the eccentric wheel.

[0008] Preferably, a rotating shaft is rotatably connected to the inner surface of the device platform, and a transmission gear is fixedly connected to one end of the rotating shaft near the drive gear, with the outer surface of the transmission gear meshing with the outer surface of the drive gear.

[0009] Preferably, an eccentric wheel is fixedly sleeved on the outer surface of the rotating shaft, and two sets of eccentric wheels are provided, with the positions of the two sets of eccentric wheels corresponding to the two sets of L-shaped plates respectively.

[0010] Preferably, the limiting clamping mechanism includes a lead screw rotatably connected inside the device platform, and a crank is provided at one end of the lead screw. The limiting clamping mechanism can stably clamp the battery plate located below the collision block, preventing it from shaking or shifting during the collision detection process.

[0011] Preferably, the outer surface of the lead screw is threaded with a displacement seat, and two sets of displacement seats are provided, with a clamping plate on the top of each set of displacement seats.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This battery production plate testing device, by introducing a synchronous and differently positioned collision mechanism between a cutter and a collision block, realizes the simulation of multiple types of damage to the plate. The introduction of the cutter simulates cutting or scratch damage, while the collision block is responsible for simulating compression and impact damage. This design makes the test closer to the actual use scenario and can more comprehensively evaluate the durability and reliability of the plate.

[0014] 2. This battery production plate testing device, through the combined use of an eccentric wheel and an L-shaped plate, realizes periodic collision testing of the plates by the collision block and the cutter. This periodic collision simulates the continuous impact scenarios that may be encountered in actual use, and conducts a more comprehensive and in-depth test on the plates in order to reveal potential problems of the plates in the long-term use process, thereby improving the effectiveness and practicality of the test.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Please see Figure 1-3 A plate testing device for battery production includes a platform 1, a horizontal plate 2 fixedly connected to the inner side of the platform 1, a shifting rod 3 movably passing through the inner side of the horizontal plate 2, a collision block 4 fixedly connected to the bottom of the shifting rod 3, a spring 5 fixedly sleeved on the outer surface of the shifting rod 3, the top and bottom ends of the spring 5 being fixedly connected to the inner side of an L-shaped plate 6 and the top of the horizontal plate 2 respectively, the top of the shifting rod 3 being fixedly connected to the L-shaped plate 6, a cutter 7 being provided at the bottom of the L-shaped plate 6, a driving mechanism being provided on the platform 1, and a limit clamping mechanism being provided on the platform 1.

[0021] With the above technical solution, when using the device, the battery plates are first placed in a suitable position on the device platform 1 (the plates are directly below the two sets of collision blocks 4 and the cutter 7). Then, the plates are stably clamped by the limiting clamping mechanism to keep them in a stable state. Finally, the drive mechanism can drive the rotating shaft 10 to rotate. With the eccentric wheel 12 moving the L-shaped plate 6 and the spring 5 rebounding, the two sets of collision blocks 4 and the cutter 7 can synchronously and periodically perform downward collision tests on the plates.

[0022] Specifically, the drive mechanism includes a motor 8 fixedly installed inside the device platform 1, and a drive gear 9 is fixedly connected to the output end of the motor 8.

[0023] With the above technical solution, after the motor 8 is turned on, it can drive the drive gear 9 to rotate. The drive gear 9 is meshed with the transmission gear 11, so the drive gear 9 will drive the transmission gear 11 and thus make it rotate.

[0024] Specifically, a rotating shaft 10 is rotatably connected to the inner surface of the device platform 1, and a transmission gear 11 is fixedly connected to one end of the rotating shaft 10 near the drive gear 9, and the outer surface of the transmission gear 11 meshes with the outer surface of the drive gear 9.

[0025] Through the above technical solution, the rotating shaft 10 will drive the eccentric wheel 12 to rotate synchronously with the transmission gear 11. During the rotation, the eccentric wheel 12 will always be in contact with the L-shaped plate 6. When the tip of the eccentric wheel 12 abuts against the L-shaped plate 6 and pushes it, the collision block 4 and the cutter 7 can indirectly contact and collide with the electrode plate.

[0026] Specifically, an eccentric wheel 12 is fixedly sleeved on the outer surface of the rotating shaft 10, and two sets of eccentric wheels 12 are provided.

[0027] With the above technical solution, the two sets of eccentric wheels 12 correspond to the two sets of L-shaped plates 6 respectively, that is, one eccentric wheel 12 can only push and push one L-shaped plate 6.

[0028] Specifically, the limiting clamping mechanism includes a lead screw 13 rotatably connected inside the device platform 1, and a crank handle 14 is provided at one end of the lead screw 13.

[0029] Through the above technical solution, the lead screw 13 is provided with threads of the same length and opposite direction from the middle to both ends, so that the two sets of shift seats 15 can move synchronously in opposite directions.

[0030] Specifically, the outer surface of the lead screw 13 is threaded with a displacement seat 15, and there are two sets of displacement seats 15. Each set of displacement seats 15 is provided with a clamping plate 16 on its top.

[0031] Through the above technical solution, during the synchronous reverse movement of the two sets of shift seats 15 along the lead screw 13, the two sets of clamping plates 16 can approach each other until they completely clamp the battery plates.

[0032] Working Principle: During the collision test of the battery plates, the plates must first be placed in a suitable position on the device platform 1, directly below the collision block 4 and the cutter 7. Then, the crank handle 14 is turned to rotate the lead screw 13. During rotation, the lead screw 13 drives two sets of shift seats 15 to move synchronously in opposite directions. This ensures stable clamping of the plates as the shift seats 15 approach each other, preventing plate displacement or shaking during the collision test, which would affect the safety and accuracy of the test. Next, the motor 8 is turned on to drive the drive gear 9. During its rotation, the drive gear 9 drives the meshing transmission gear 11 to rotate synchronously. Through the rotating shaft 10, the two sets of eccentric wheels 12 push down on the L-shaped plate 6. During this process, the L-shaped plate 6 is pushed down gradually, moving the shift rod 3. The collision block 4 moves down synchronously (the L-shaped plate 6 will compress the spring 5 during the downward movement, causing it to deform). During this time, the cutter 7 will also move down synchronously. That is, the cutter 7 and the two sets of collision blocks 4 will contact and collide with the electrode plate during the synchronous downward movement (the collision positions with the electrode plate are different). When the tip of the eccentric wheel 12 moves away from the L-shaped plate 6, the L-shaped plate 6 will be pushed up gradually by the elastic reset action of the spring 5. That is, the two sets of collision blocks 4 and the cutter 7 will gradually move away from the electrode plate. When the tip of the eccentric wheel 12 pushes the L-shaped plate 6 down again, the collision block 4 and the cutter 7 will squeeze and collide with the electrode plate again. This process is repeated, allowing the collision block 4 and the cutter 7 to periodically conduct collision tests on the electrode plate. The introduction of the cutter 7 simulates cutting or scratch damage, while the collision block 4 continues to be responsible for simulating compression and impact damage, realizing the simulation of multiple types of damage to the electrode plate.

[0033] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
