Description

Technical Field

[0001] This utility model relates to the field of power battery cover plate processing technology, specifically a positioning mechanism for a power battery cover plate detection device. Background Technology

[0002] Power batteries are storage batteries that provide power to electric vehicles, electric trains, and other similar vehicles, and their cost accounts for 35%-50% of the total cost of an electric vehicle. The main types include ternary lithium batteries, lithium iron phosphate batteries, lithium manganese oxide batteries, and others.

[0003] In the production of power batteries, accurate inspection of battery covers is a crucial step in ensuring product quality. However, existing power battery cover inspection devices suffer from complex positioning mechanisms and cumbersome operation, resulting in low inspection efficiency. Some positioning mechanisms lack good synchronization and stability, making it difficult to achieve precise positioning of the cover and affecting the accuracy of the inspection results. Therefore, there is an urgent need for a new positioning mechanism for power battery cover inspection devices. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning mechanism for a power battery cover detection device to solve the problems mentioned in the background art.

A moving block is fixedly connected to the top of each first slider. The top of the workbench is fixedly connected to a second slide rail, and two second sliders are slidably connected to the top of the second slide rail. A connecting rod is hinged to the top of each first slider. The ends of each pair of connecting rods away from the first slider are respectively hinged to the second slider. Cylinders are fixedly connected to both ends of the outer shell. Positioning plates are fixedly connected to the tops of the two front moving blocks and the two rear moving blocks.

[0006] Preferably, a push plate is fixedly connected to the top of each of the two second sliders, and the output arms of the two cylinders are respectively fixedly connected to the push plate.

[0007] Preferably, the top of the outer casing has two sliding openings, and each pair of movable blocks is slidably disposed within the two sliding openings.

[0008] Preferably, the bottom of the workbench is fixedly connected to four support legs.

[0009] Preferably, each of the two positioning plates has a telescopic groove at one end that is close to each other, and a telescopic block is slidably arranged inside each of the two telescopic grooves. A clamping plate is fixedly connected to one end of each of the two telescopic blocks that is close to each other, and multiple springs are fixedly connected to one end of each of the two telescopic blocks that are opposite to each other.

[0010] Preferably, the ends of the multiple springs furthest from the telescopic block are fixedly connected to the positioning plate, and the ends of the two clamping plates adjacent to each other are respectively fixedly connected to rubber pads.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: First, this utility model uses a cylinder to provide power, and with the guide structure of the slide rail and slider, as well as the linkage design of the connecting rod, it ensures that the positioning plate moves smoothly and synchronously. When the cylinder is started, it can quickly and accurately position the power battery cover, meet the position fixation requirements during testing, and effectively improve the accuracy and efficiency of testing.

[0012] Secondly, in this utility model, the positioning plate is equipped with a telescopic groove, a telescopic block, a spring, and a rubber pad.

[0015] 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.

[0016] This utility model provides the following technical solution: Example 1 Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A positioning mechanism for a power battery cover detection device includes a workbench 1, with a housing 2 fixedly connected to the top of the workbench 1. The top of the workbench 1 is fixedly connected to two first slide rails 3, and two first sliders 4 are slidably connected to each first slide rail 3. A moving block 5 is fixedly connected to the top of each first slider 4. The top of the workbench 1 is fixedly connected to a second slide rail 6, and two second sliders 7 are slidably connected to the top of the second slide rail 6. A connecting rod 8 is hinged to the top of each first slider 4. The ends of each pair of connecting rods 8 away from the first slider 4 are respectively hinged to the second slider 7. Cylinders 9 are fixedly connected to both ends of the outer shell 2. Positioning plates 10 are fixedly connected to the tops of the two front moving blocks 5 and the two rear moving blocks 5.

[0017] The tops of the two second sliders 7 are fixedly connected to push plates 11, and the output arms of the two cylinders 9 are fixedly connected to push plates 11 respectively.

[0018] The top of the outer casing 2 has two sliding openings, and each pair of movable blocks 5 is slidably set in the two sliding openings.

[0019] The bottom of the workbench 1 is fixedly connected with four support legs 12.

[0020] Through the above technical solution, the top of the workbench 1 is fixed with the outer shell 2 as a protective and support structure. Two sets of first slide rails 3 are provided on the surface of the workbench 1, with two first sliders 4 slidably connected to each set of slide rails. A moving block 5 is connected to the top of each first slider 4. The workbench 1 also has a second slide rail 6, with two second sliders 7 slidably connected to it. The first sliders 4 and second sliders 7 are hinged together by a connecting rod 8 to form a linkage structure. Cylinders 9 are installed at both ends of the outer shell 2. The cylinder output arms are connected to the push plates 11 on the top of the second sliders 7. A positioning plate 10 is fixed to the top of the moving block 5. The outer shell 2 has a sliding opening for the moving block 5 to slide. The support legs 12 at the bottom of the workbench 1 provide overall support. When the cylinder 9 is activated, its output arm… Pushing the push plate 11 causes the second slider 7 to slide along the second slide rail 6. When the second slider 7 moves, it pulls or pushes the first slider 4 along the first slide rail 3 through the connecting rod 8. Due to the hinge relationship of the connecting rod 8, the first sliders 4 on both sides will move closer or further away synchronously. The first slider 4 drives the moving block 5 and the top positioning plate 10 to move synchronously, ultimately realizing the clamping, positioning or loosening of the power battery cover by the two positioning plates 10. Power is provided by the cylinder 9. With the guide structure of the slide rail and slider and the linkage design of the connecting rod, the positioning plate moves smoothly and synchronously, which can quickly achieve accurate positioning of the cover, meet the position fixation requirements during testing, and has a simple structure and is easy to operate.

[0021] Example 2 Please see Figure 1 , Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the following is obtained: telescopic grooves are provided at the close ends of the two positioning plates 10, telescopic blocks 13 are slidably arranged inside the two telescopic grooves, clamping plates 14 are fixedly connected at the close ends of the two telescopic blocks 13, and multiple springs 15 are fixedly connected at the opposite ends of the two telescopic blocks 13.

[0022] The ends of multiple springs 15 away from the telescopic block 13 are fixedly connected to the positioning plate 10, and the ends of the two clamping plates 14 close to each other are fixedly connected to rubber pads 16.

[0023] Through the above technical solution, a telescopic groove is opened at one end of the two positioning plates 10 facing each other, and a telescopic block 13 is slidably arranged in the groove. The end of the telescopic block 13 near the cover plate is connected to the clamping plate 14, and the other end is connected to multiple springs 15. The other end of the springs 15 is fixed to the positioning plate 10. A rubber pad is installed on the side of the clamping plate 14 that contacts the cover plate. When the positioning plate 10 approaches the cover plate under the drive of Embodiment 1, the clamping plate 14 contacts the cover plate first. When the positioning plate 10 continues to move, the telescopic block 13 will compress the springs 15 and retract into the telescopic groove. The elastic force of the springs 15 reacts to the telescopic block 13, so that the clamping plate 14 is tightly attached to the surface of the cover plate. The elastic buffering effect of the springs 15 allows the clamping force to be adaptively adjusted, which can not only firmly clamp cover plates with slight differences in size, but also avoid deformation or damage to the cover plate caused by rigid clamping. The rubber pad 16 further increases the friction to prevent slippage, and at the same time avoids scratches caused by direct contact between the metal clamping plate and the cover plate, thus improving the safety and adaptability of the positioning process.
