A power battery transmission detection device

Abstract

This utility model provides a power battery transmission and testing device, including a worktable. An electric guide rail is mounted on the upper side of the worktable, and a placement plate is slidably fitted onto the electric guide rail. An installation groove is formed on the upper side of the placement plate, and a clamping mechanism is installed inside the installation groove. A mounting frame is fixedly connected to the upper side of the placement plate, and a pressure plate is slidably fitted onto the inner wall of the mounting frame. Two trapezoidal plates are fixedly connected to one side of the pressure plate, and rubber wheels are rotatably fitted onto the lower side of the trapezoidal plates. By setting a synchronization mechanism, the transmission, fixing, and testing processes are linked. When the pressure plate moves, it drives the toothed plate to slide, which, through gears, connecting rods, bevel gears, etc., drives the lead screw to rotate, causing the testing probe on the lifting plate to automatically approach the power battery for testing. No additional power source is needed to separately control the probe's lifting and lowering. This linked design simplifies the operation process, shortens the testing time, and improves overall work efficiency.

Description

Technical Field

[0001] This utility model relates to the field of battery testing equipment technology, and more specifically, to a power battery transmission testing device. Background Technology

[0002] As a core component in new energy vehicles, energy storage systems, and other fields, the quality and performance of power batteries directly affect the safety and reliability of products. In the production and manufacturing process of power batteries, the transmission and testing links are key steps to ensure product quality and play a decisive role in ensuring the stable performance of power batteries. With the rapid development of the power battery industry, the market's requirements for its production efficiency and quality control are becoming increasingly stringent, making efficient and accurate transmission and testing devices increasingly important.

[0003] However, most power battery transmission testing devices on the market currently have certain positioning and probe height adjustment functions, but the clamping positioning and probe height adjustment are independent of each other. The operation is cumbersome and prone to asynchronous adjustment. When replacing power batteries of different heights, it is necessary to manually adjust the positioning position of the clamping structure first, and then adjust the probe height separately. This not only wastes time, but may also affect the testing accuracy due to adjustment errors.

[0004] Therefore, we have made improvements to this and proposed a power battery transmission detection device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steam curing device for manufactured sand concrete to solve the problems mentioned in the background technology. This utility model realizes the linkage of transmission, fixing and detection processes by setting a synchronization mechanism, eliminating the need for an additional power source to control the probe lifting and lowering separately. This linkage design simplifies the operation process, shortens the detection time and improves the overall work efficiency.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A power battery transmission testing device includes a workbench with an electric guide rail on its upper side. A placement plate is slidably fitted on the electric guide rail. An installation groove is formed on the upper side of the placement plate, and a clamping mechanism is installed inside the installation groove. A mounting frame is fixedly connected to the upper side of the placement plate, and a pressure plate is slidably fitted to the inner wall of the mounting frame. Two trapezoidal plates are fixedly connected to one side of the pressure plate, and rubber wheels are rotatably fitted to the lower side of the trapezoidal plates. A protective shell is fixedly connected to the upper side of the placement plate, and a mounting shell is also fixedly connected to the upper side of the placement plate. A lifting plate is slidably fitted to one side of the mounting shell, and multiple detection probes are mounted on the lower side of the lifting plate. A synchronization mechanism is installed inside the protective shell and the mounting shell.

[0008] Furthermore, the clamping mechanism includes a bidirectional lead screw rotatably engaged with the inner wall of the mounting groove, a drive motor is installed on one side of the placement plate, and two movable plates are slidably engaged with the inner wall of the mounting groove, with clamping plates fixedly connected to the opposite sides of the two movable plates.

[0009] Furthermore, the output end of the drive motor is fixedly connected to one end of the bidirectional lead screw, both of the moving plates are threaded onto the bidirectional lead screw, and protective pads are fixedly connected to the opposite sides of the two clamping plates.

[0010] Furthermore, the synchronization mechanism includes a connecting rod rotatably engaged with one side of the inner wall of the protective housing. A gear is fixedly connected to one end of the connecting rod. A toothed plate is slidably engaged with the side of the protective housing near the mounting frame. A sliding sleeve is fixedly connected to one side of the toothed plate. A fixing frame is fixedly connected to one side of the mounting frame. A sliding rod is installed on one side of the fixing frame. A lead screw is rotatably engaged with the inner wall of the mounting housing. One end of the connecting rod extends into the interior of the mounting housing and is fixedly connected to a driving bevel gear.

[0011] Furthermore, the sliding sleeve is slidably fitted onto the sliding rod, the gear meshes with the gear plate, and one end of the lifting plate is threaded onto the lead screw.

[0014] Furthermore, the limiting rod is slidably fitted on one side of the mounting bracket, and the two ends of the spring are fixedly connected to the mounting bracket and the pressure plate, respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model achieves linkage between transmission, fixing and detection processes by setting a synchronization mechanism. When the pressure plate moves, it drives the toothed plate to slide. Through gears, connecting rods, bevel gears and other transmissions, it drives the lead screw to rotate, so that the detection probe on the lifting plate automatically approaches the power battery for detection. There is no need for an additional power source to control the lifting of the probe separately. This linkage design simplifies the operation process, shortens the detection time and improves the overall work efficiency.

[0017] 2. This utility model, by setting up a combination structure of clamping mechanism, pressure plate and rubber wheel, the bidirectional screw in the clamping mechanism, driven by the drive motor, makes the two clamping plates move relative to each other, so as to achieve stable clamping of the power battery. With the protective pad on the clamping plate, damage to the battery surface is avoided and the stability of battery fixation is improved. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please refer to Figure 1-5A power battery transmission detection device includes a workbench 1, an electric guide rail 2 on the upper side of the workbench 1, a placement plate 3 slidably fitted on the electric guide rail 2, an installation groove 4 on the upper side of the placement plate 3, a clamping mechanism 5 inside the installation groove 4, a mounting frame 6 fixedly connected to the upper side of the placement plate 3, a pressure plate 7 slidably fitted on the inner wall of the mounting frame 6, two trapezoidal plates 8 fixedly connected to one side of the pressure plate 7, rubber wheels 9 rotatably fitted on the lower side of the trapezoidal plates 8, a protective shell 10 fixedly connected to the upper side of the placement plate 3, and a mounting shell 11 fixedly connected to the upper side of the placement plate 3; a lifting plate 12 slidably fitted to one side of the mounting shell 11, multiple detection probes 13 mounted on the lower side of the lifting plate 12, and a synchronization mechanism 14 inside the protective shell 10 and the mounting shell 11. Two baffles 16 fixedly connected to the upper side of the placement plate 3. A limit rod 17 fixedly connected to the upper side of the pressure plate 7, with a spring 18 sleeved on the limit rod 17. The limiting rod 17 is slidably fitted on one side of the mounting bracket 6, and the two ends of the spring 18 are fixedly connected to the mounting bracket 6 and the pressure plate 7, respectively. The electric guide rail 2 facilitates the transport and testing of the power battery. The qualified power battery is transported to the next process through the conveyor belt assembly, which improves the transmission efficiency. The combination of the pressure plate 7 and the spring 18 can initially fix the power battery and reduce shaking during the transmission process. The test probe 13 is a FlukeBT521+BTL21 intelligent test probe group (which is existing technology and will not be described in detail in this article).

[0027] Specifically, after the electric guide rail 2 is powered on, it generates power through the internal drive mechanism, which drives the placement plate 3 to slide on the guide rail, realizing the transfer of the power battery on the worktable. When the placement plate 3 moves to the designated position, the power battery is placed on the placement plate 3 and pushed towards the baffle 16, which drives the pressure plate 7 to rise and compresses the spring 18. Under the action of the spring 18, the power battery can be pre-compressed to a certain extent. The limit rod 17 slides on the mounting bracket 6, which plays a guiding and limiting role, ensuring that the pressure plate 7 moves smoothly.

[0028] In this embodiment, the clamping mechanism 5 includes a bidirectional lead screw 51 rotatably engaged with the inner wall of the mounting groove 4. A drive motor 52 is mounted on one side of the placement plate 3. Two movable plates 53 are slidably engaged with the inner wall of the mounting groove 4, and clamping plates 54 are fixedly connected to opposite sides of the two movable plates 53. The output end of the drive motor 52 is fixedly connected to one end of the bidirectional lead screw 51. Both movable plates 53 are threaded onto the bidirectional lead screw 51, and protective pads 15 are fixedly connected to opposite sides of the two clamping plates 54. Through the cooperation of the drive motor 52 and the bidirectional lead screw 51, the power battery can be clamped and fixed accurately and stably, preventing the battery from shaking or shifting during transmission and testing, thus improving testing accuracy. At the same time, the protective pads 15 effectively protect the battery surface.

[0029] Specifically, after the drive motor 52 starts, the output shaft drives the bidirectional lead screw 51 to rotate. Since both moving plates 53 are threaded onto the bidirectional lead screw 51 and the threads at both ends of the bidirectional lead screw 51 are in opposite directions, when the bidirectional lead screw 51 rotates, the two moving plates 53 will move relative to each other along the inner wall of the mounting groove 4, thereby driving the clamping plate 54 to move closer or further away, thus clamping or releasing the power battery. The protective pad 15 is made of soft material, which can avoid damage to the battery surface when clamping the power battery.

[0030] In this embodiment, the synchronization mechanism 14 includes a connecting rod 141 rotatably engaged with one side of the inner wall of the protective shell 10. A gear 142 is fixedly connected to one end of the connecting rod 141. A toothed plate 143 is slidably engaged with the side of the protective shell 10 near the mounting bracket 6. A sliding sleeve 144 is fixedly connected to one side of the toothed plate 143. A fixing bracket 145 is fixedly connected to one side of the mounting bracket 6. A sliding rod 146 is mounted on one side of the fixing bracket 145. A lead screw 147 is rotatably engaged with the inner wall of the mounting shell 11. One end of the connecting rod 141 extends into the interior of the mounting shell 11 and is fixedly connected to a driving bevel gear 148. A driven bevel gear 149, meshing with the driving bevel gear 148, is fixedly connected to the lower end of the lead screw 147. The sliding sleeve 144 is slidably engaged with the sliding rod 146. The gear 142 meshes with the toothed plate 143. One end of the lifting plate 12 is threaded onto the lead screw 147. The synchronization mechanism 14 enables the linkage between the movement of the pressure plate 7 and the lifting of the detection probe 13, which closely integrates the transmission, fixing and detection processes, simplifies the detection process, improves detection efficiency, eliminates the need for an additional power source to separately control the lifting of the detection probe 13, reduces the complexity and energy consumption of the device, and ensures the stability and continuity of the detection process.

[0031] Specifically, when the pressure plate 7 moves, it causes the toothed plate 143 to slide on the protective shell 10. The movement of the toothed plate 143 causes the gear 142 that meshes with it to rotate. The gear 142 drives the active bevel gear 148 to rotate through the connecting rod 141. The active bevel gear 148 meshes with the driven bevel gear 149, thereby causing the lead screw 147 to rotate. Since one end of the lifting plate 12 is threaded onto the lead screw 147, when the lead screw 147 rotates, the lifting plate 12 will move up and down along the inner wall of the mounting shell 11, thereby causing the detection probe 13 to move closer to or away from the power battery, thus realizing the detection of the power battery. When the pressure plate 7 moves up and resets, the detection probe 13 will also move up and reset synchronously.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
