Description

Technical Field

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

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental controls. With the development of science and technology, lithium-ion batteries have become mainstream. After production, lithium-ion batteries require various performance tests, with weight testing being a crucial part, necessitating the use of testing equipment specifically designed for lithium-ion battery production.

[0003] Patent CN219253316U discloses a testing device for lithium battery production. This testing device uses a first belt conveyor to transport the lithium batteries to be tested. When the lithium battery moves above the toothed belt, the weight of the lithium battery itself will cause the turntable to move downward. The downward movement of the turntable will cause the connecting plate to move downward and contact the weighing sensor. After contact, the weighing sensor can measure the weight of the lithium battery, which is very convenient.

[0004] However, the aforementioned testing device for lithium battery production does not have relevant components to adjust the position of untested batteries during the conveying process. As a result, when the first belt conveyor moves the batteries to the surface of the toothed belt, some batteries do not adhere to its surface, leading to errors in the testing results and low accuracy of the testing device. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this application provides a testing device for lithium battery production, which solves the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this application provides the following technical solution: a testing device for lithium battery production, comprising a conveyor frame and a testing mechanism for detecting the weight of the battery. The top right side of the conveyor frame is connected to an adjustment mechanism for adjusting the position of the battery during transport. The adjustment mechanism includes a connecting plate and an adjustment plate. The connecting plate is disposed on the upper right side of the conveyor frame, and the top of the adjustment plate is connected to the bottom of the connecting plate. The testing mechanism is connected to the left side of the conveyor frame.

[0009] By adopting the above technical solution, the position of batteries of different widths can be adjusted to the center using the adjustment plate at the bottom of the connecting plate, thereby improving the accuracy of battery weight detection.

[0010] Preferably, the adjustment mechanism further includes a fixed frame and an arc plate. The bottom of the fixed frame is connected to the top right side of the conveyor frame, the arc plate is connected to the front side of the fixed frame, a motor is connected to the top of the arc plate, and a bidirectional screw is connected to the output shaft of the motor. One end of the bidirectional screw is rotatably connected to the rear side of the inner wall of the fixed frame.

[0011] By adopting the above technical solution, the motor output shaft at the top of the arc-shaped plate in front of the fixed frame can be used to drive the bidirectional screw to rotate, ensuring that the two adjusting plates move towards or away from each other.

[0012] Preferably, the adjustment mechanism further includes an internal threaded ring and a sliding groove. The inner wall of the internal threaded ring is threadedly connected to the surface of the bidirectional screw. A slider is connected to the top of the internal threaded ring. The sliding groove is opened on the top of the fixed frame and is slidably connected to the side of the slider.

[0013] By adopting the above technical solution, the internal threaded ring can be moved in opposite directions by rotating the bidirectional screw, under the premise that the slider and the groove are slidably connected, thus ensuring the stability of the movement of the internal threaded ring.

[0014] Preferably, the detection mechanism includes a base plate and a placement box, the top of the base plate is connected to the bottom left side of the conveyor frame, and the sides of the placement box are connected to the front and rear sides of the base plate.

[0015] By adopting the above technical solution, the placement boxes on both sides of the base plate can be used to facilitate the placement of the tested batteries.

[0016] Preferably, the detection mechanism further includes a main rod and a rotating groove. The bottom of the main rod is connected to the center of the top of the base plate. The rotating groove is opened at the top of the main rod. A rotating ball is rotatably connected to the inner wall of the rotating groove. A connecting rod is connected to the top of the rotating ball. A top plate is connected to the top of the connecting rod.

[0017] By adopting the above technical solution, the rotating connection between the rotating groove at the top of the main rod and the rotating ball at the bottom of the connecting rod can be utilized, providing room for the tilting of the top plate.

[0018] Preferably, the detection mechanism further includes a baffle and a slide plate, the bottom of the baffle being connected to the top left side of the top plate, and the slide plate being connected to the front and rear sides of the top plate respectively.

[0019] By adopting the above technical solution, the baffle can be used to prevent the battery from falling off the top plate surface, and the sliding plate can be used to reduce the impact force when the battery falls into the placement box.

[0020] Preferably, the detection mechanism further includes a weighing device and a controller, wherein the bottom of the weighing device is connected to the top of the top plate, and the rear side of the controller is connected to the front side of the conveyor frame.

[0021] By adopting the above technical solution, the weight of the battery can be detected by a weighing device, and the controller can control the switch of the electric push rod after receiving the weighing data, so as to separate qualified batteries from unqualified batteries.

[0022] Preferably, the detection mechanism further includes a lower hinge frame and a guide plate. The rear side of the lower hinge frame is connected to the front side of the main rod. An electric push rod is hinged to the front side of the lower hinge frame. One end of the electric push rod is hinged to an upper hinge frame. The top of the upper hinge frame is connected to the front side of the bottom of the top plate. The right side of the guide plate is connected to the left side of the conveyor frame.

[0023] By adopting the above technical solution, the tilt angle of the top plate can be adjusted by the extension and retraction of the electric push rod between the lower and upper hinge frames, allowing it to slide into different placement boxes. Furthermore, the guide plate reduces the impact force of the battery falling from the conveyor frame onto the weighing surface, thus reducing the possibility of the battery being damaged during the testing process.

[0024] (III) Beneficial Effects

[0025] This application provides a testing device for lithium battery production. It has the following advantages:

[0026] 1. This lithium battery production testing device, through the setting of an adjustment mechanism, has a motor output shaft at the top of the arc-shaped plate on the front side of the fixed frame rotating to drive a bidirectional screw to rotate. The rotation of the bidirectional screw drives the internal threaded ring to move towards each other. The movement of the internal threaded ring drives the slider to move within the slide groove, and at the same time drives the adjustment plate at the bottom of the connecting plate to move to the target position. This adjusts the position of the moving battery, avoiding excessive deviation in battery position during weighing that would affect the accuracy of the test results, thus improving the precision of the test results and enhancing the cost-effectiveness of the testing device.

[0027] 2. This lithium battery production testing device, through the setting of a testing mechanism, allows the battery to slide onto the weighing surface on the right side of the baffle via a guide plate for weighing. If the weighing data is within the range of the data entered by the controller, the controller controls the electric push rod hinged to the lower hinge frame on the side of the main rod at the top of the base plate to shorten. The shortening of the electric push rod causes the top plate connected to the upper hinge frame to rotate clockwise, thereby causing the battery to fall into the placement box along the slide plate. At the same time, it causes the rotating ball at the bottom of the connecting rod to rotate in the rotating groove, reducing the energy required for the operation of the testing device and reducing the operating cost of the testing device.

[0037] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] Reference Figure 3 and Figure 4This application provides a testing device for lithium battery production, including a conveyor frame 1 and a testing mechanism 3 for detecting the weight of batteries. An adjustment mechanism 2 for adjusting the position of batteries during transport is connected to the top right side of the conveyor frame 1. The adjustment mechanism 2 includes a connecting plate 208 and an adjustment plate 209. The connecting plate 208 is located on the upper right side of the conveyor frame 1, and the top of the adjustment plate 209 is connected to the bottom of the connecting plate 208. A fixing frame 201 is connected to the top right side of the conveyor frame 1, and an arc-shaped plate 202 is connected to the front of the fixing frame 201. A motor 203 (model LCM) is connected to the top of the arc-shaped plate 202. (100-200), the output shaft of motor 203 is connected to a bidirectional screw 204. One end of the bidirectional screw 204 is rotatably connected to the rear side of the inner wall of the fixed frame 201. An internal threaded ring 205 is threaded onto the surface of the bidirectional screw 204. A slider 206 is connected to the top of the internal threaded ring 205. A groove 207 is opened on the top of the fixed frame 201. The groove 207 is slidably connected to the side of the slider 206. The detection mechanism 3 is connected to the left side of the conveyor frame 1. The output shaft of motor 203 on the top of the arc plate 202 on the front side of the fixed frame 201 rotates, driving the bidirectional screw 204 to rotate. The rotation of the bidirectional screw 204 drives the internal threaded ring 205 to move towards each other. The movement of the internal threaded ring 205 drives the slider 206 to move in the groove 207. At the same time, it drives the adjustment plate 209 at the bottom of the connecting plate 208 to move to the target position, adjusting the position of the moving battery.

[0039] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6In one aspect of this embodiment, the detection mechanism 3 includes a base plate 301 and a placement box 302. The top of the base plate 301 is connected to the bottom left side of the conveyor frame 1, and the sides of the placement box 302 are connected to the front and rear sides of the base plate 301. A sponge block is provided at the bottom of the inner wall of the placement box 302. A main rod 303 is connected to the center of the top of the base plate 301. A rotating groove 304 is opened at the top of the main rod 303. A rotating ball 305 is rotatably connected to the inner wall of the rotating groove 304. A connecting rod 306 is connected to the top of the rotating ball 305. A top plate 307 is connected to the top of the connecting rod 306. A baffle 308 is connected to the left side of the top of the top plate 307. Slide plates 309 are connected to both the front and rear sides of the top plate 307. A weighing device 310 is connected to the top of the top plate 307. A controller 315 (model Siemens S7-1500) is connected to the front of the conveyor frame 1. The controller 315 has been pre-programmed with the operating mode of the motor 203 for different battery models during testing. The qualified weight range controls the extension and retraction of the electric actuator 312. A lower hinge frame 311 is connected to the front of the main rod 303. The electric actuator 312 (model SIG-200-3) is hinged to the front of the lower hinge frame 311. One end of the electric actuator 312 is hinged to an upper hinge frame 313. The top of the upper hinge frame 313 is connected to the front bottom of the top plate 307. A guide plate 314 is connected to the left side of the conveyor frame 1. The battery slides from the guide plate 314 onto the weighing device 31 on the right side of the baffle 308. Weighing is performed on the surface. If the weighing data is within the range of data entered by the controller 315, the controller 315 controls the electric push rod 312 hinged to the lower hinge frame 311 on the side of the main rod 303 at the top of the base plate 301 to shorten. The shortening of the electric push rod 312 causes the top plate 307 connected to the upper hinge frame 313 to rotate clockwise, thereby causing the battery to fall into the placement box 302 along the slide plate 309. At the same time, it causes the ball bearing 305 at the bottom of the connecting rod 306 to rotate in the rotating groove 304.

[0040] All electrical devices in this plan are powered by an external power source.

[0041] Working principle: During use, the controller 315 controls the motor 203 to start. The output shaft of the motor 203 on the top of the arc plate 202 on the front side of the fixed frame 201 rotates, driving the bidirectional screw 204 to rotate. The rotation of the bidirectional screw 204 drives the internal threaded ring 205 to move towards each other. The movement of the internal threaded ring 205 drives the slider 206 to move within the slide groove 207, and at the same time drives the adjusting plate 209 at the bottom of the connecting plate 208 to move to the target position, adjusting the position of the moving battery. After the conveyor 1 drives the battery to the left, the battery slides off the guide plate 314 onto the surface of the weighing device 310 on the right side of the baffle 308 for weighing. If the weighing data is within the data range entered by the controller 315, the controller 315 controls the lower side of the main rod 303 on the top of the base plate 301 to move. The electric push rod 312, which is hinged to the hinge frame 311, shortens. The shortening of the electric push rod 312 causes the top plate 307 connected to the upper hinge frame 313 to rotate clockwise, thereby causing the battery to fall into the placement box 302 on the front side along the slide plate 309. At the same time, it causes the ball bearing 305 at the bottom of the connecting rod 306 to rotate in the rotating groove 304. If the weighing data exceeds the data range entered by the controller 315, the controller 315 controls the electric push rod 312, which is hinged to the lower hinge frame 311 on the side of the main rod 303 at the top of the base plate 301, to extend. The extension of the electric push rod 312 causes the top plate 307 connected to the upper hinge frame 313 to rotate counterclockwise, thereby causing the battery to fall into the placement box 302 on the rear side along the slide plate 309. At the same time, it causes the ball bearing 305 at the bottom of the connecting rod 306 to rotate in the rotating groove 304.
