Description

Technical Field

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

[0002] The testing device is used for testing the pressure of battery electrode groups. During the coating process of battery plates, due to the instability of the coating machine, there are slight deviations in the thickness of the produced plates. Thickness deviations are permissible within a certain range, but they must meet the process requirements. Only when the thickness is within the process requirements can the pressure of the electrode group be guaranteed to be consistent when it is installed in the battery case, thereby improving the consistency of the battery. Therefore, a testing device is needed to test the pressure of the electrode groups.

[0003] For example, patent application number 201921635219.3 discloses a battery electrode pressure detection device, including a base plate. Support plates are fixedly mounted on both sides of the top of the base plate. Multiple base plates are mounted on the top of the base plate. An extension rod is mounted on one side of each base plate. A return spring is located inside each base plate. Limiting blocks are fixedly mounted on the top and bottom of the extension rod. A servo motor is mounted on one side of the top of the support plate. A rotating rod is mounted on one side of the servo motor, and the servo motor is connected to the rotating rod. The outer surface of the rotating rod is provided with a first thread and a second thread. A limiting ring is fixedly mounted at the center of the rotating rod. When fixing battery electrode groups of different sizes, the size of the hollow area can be changed by stretching the extension rod between the base plates. Then, the electrode group is placed into the hollow area. After releasing, the elasticity of the return spring pulls the extension rod back, tightly securing the electrode group, thus expanding the application range of the detection device.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, it is found that while the aforementioned equipment can solve the problems of not being able to detect battery groups of different models, having a small range of applications, low detection accuracy, inconvenience in operation and use, and poor performance, its application is still limited.

[0005] However, during use, the infrared ranging sensor used to detect the distance between the two clamps lacks a protective structure, which can lead to damage to the sensor head when the user handles or prevents the battery from being touched. Utility Model Content

[0023] 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.

[0024] like Figures 1 to 4 As shown, this utility model provides a pressure testing device for battery production, including a pressure testing platform 1, a motor 2, a bidirectional screw 3, an infrared distance sensor 4, a pressure sensor 5, a first pressure plate 6, and a second pressure plate 7.

The pressure sensor 5 is embedded in the bottom right side of the first pressure plate 6, and the inner wall of the first pressure plate 6 is connected to the bidirectional screw 3. The left side of the surface is threaded, the inner wall of the second pressure plate 7 is threaded to the right side of the surface of the bidirectional screw 3, the infrared distance sensor 4 is located on the top of the first pressure plate 6, the top right side of the first pressure plate 6 is fixedly connected to the mounting plate 8, the right side of the mounting plate 8 is fixedly connected to the mirror protective plate 9, the mirror protective plate 9 is transparent, the top of the mirror protective plate 9 is inserted with the covering mechanism 10, the two sides of the bottom left side of the first pressure plate 6 and the two sides of the bottom right side of the second pressure plate 7 are fixedly connected to the limit components 11, and the top of the first pressure plate 6 is fixedly connected to the connecting component 12.

[0025] refer to Figure 3The covering mechanism 10 includes a semi-ring connector 101, the bottom of which is inserted into the top of the mirror protective plate 9. A semi-ring protective sleeve 102 is fixedly connected to the left side of the semi-ring connector 101, and side protective plates 103 are fixedly connected to both sides of the bottom of the semi-ring protective sleeve 102.

[0026] As a technical optimization of this utility model, by setting up a covering mechanism 10, during the process of using the mirror protective plate 9 to protect the detection area of ​​the infrared distance sensor 4, the user can also insert the semi-ring connector 101 into the top of the mirror protective plate 9, so that the semi-ring protective sleeve 102 covers and protects the top of the surface of the detection area of ​​the infrared distance sensor 4. Then, the side protective plate 103 can protect the front and rear sides of the detection area of ​​the infrared distance sensor 4, further expanding the protection range and the protection effect.

[0027] refer to Figure 1 The limiting component 11 includes a limiting rod 111. The inner side of the limiting rod 111 is fixedly connected to the two sides of the bottom left side of the first pressure plate 6 and the two sides of the bottom right side of the second pressure plate 7. Limiting grooves 112 are opened on the front and rear sides of the bottom sides of both sides of the pressure testing platform 1. The inner wall of the limiting groove 112 is slidably connected to the surface of the limiting rod 111.

[0028] As a technical optimization of this utility model, by setting a limiting component 11, during the transmission process between the first pressure plate 6 and the second pressure plate 7 through the bidirectional screw 3, the sliding cooperation between the limiting rod 111 and the limiting groove 112 can be used to limit the rotation of the first pressure plate 6 and the second pressure plate 7, preventing the first pressure plate 6 and the second pressure plate 7 from rotating directly during the driving process.

[0029] refer to Figure 2 The connecting component 12 includes an elastic clamping member 121 for clamping the infrared distance sensor 4. The bottom of the elastic clamping member 121 is fixedly connected to the top of the first pressure plate 6. The elastic clamping member 121 is sleeved on the surface of the infrared distance sensor 4. Limiting rings 122 are sleeved on both sides of the surface of the infrared distance sensor 4.

[0030] As a technical optimization of this utility model, by setting the connecting component 12, when the infrared distance sensor 4 suffers internal structural aging and damage, the user can first remove the semi-ring connector 101, then pull the infrared distance sensor 4 upward to pull it out of the elastic clamp 121, and then insert the new infrared distance sensor 4 into the elastic clamp 121 and clamp it with the elastic clamp 121 to facilitate the quick installation of the new infrared distance sensor 4. At the same time, the two limiting rings 122 can limit the installation of the infrared distance sensor 4 to the left and right, ensuring the stability of the infrared distance sensor 4 after installation.

[0031] refer to Figure 4 A lifting sleeve 13 is movably fitted at the bottom of the surface of the mirror protective plate 9, and a cleaning sleeve 14 is movably fitted at the bottom of the surface of the mirror protective plate 9. The inner wall of the cleaning sleeve 14 is in contact with the surface of the mirror protective plate 9, and the surface of the cleaning sleeve 14 is fixedly connected to the inner wall of the lifting sleeve 13.

[0032] As a technical optimization of this utility model, by setting up a lifting sleeve 13 and a cleaning sleeve 14, when dust accumulates on the lower surface of the mirror protective plate 9 after long-term use, the user can lift the lifting sleeve 13 up and down, and then the lifting sleeve 13 will drive the cleaning sleeve 14 to clean both sides of the mirror protective plate 9, thereby ensuring the clarity of the mirror protective plate 9.

[0033] refer to Figure 3 The top two sides of the lifting sleeve 13 are fixedly connected to the right side of the top, and the top of the connecting member 15 is fixedly connected to the bottom of the right side of the semi-ring connector 101.

[0034] As a technical optimization of this utility model, by setting a linkage 15, when the user pulls the semi-ring connector 101 up and down to take it out or install it, the linkage 15 will drive the lifting sleeve 13 to move up and down, so that the mirror protective plate 9 can be cleaned simultaneously during the installation or removal of the semi-ring connector 101.

[0035] refer to Figure 3 The left top of the linkage 15 is fixedly connected to the reinforcement 16, and the other end of the reinforcement 16 is fixedly connected to the left side of both sides of the top of the lifting sleeve 13. The left sides of both sides of the mounting plate 8 are fixedly connected to the triangular reinforcement plate 17, and the left side of the triangular reinforcement plate 17 is fixedly connected to the top right side of the first pressure plate 6.

[0036] As a technical optimization of this utility model, by setting the reinforcement 16, the installation strength between the linkage 15 and the lifting sleeve 13 can be improved, thus avoiding breakage. Furthermore, by setting the triangular reinforcement plate 17, the connection strength between the mounting plate 8 and the first pressure plate 6 can be improved, further ensuring the protection strength.

[0037] The working principle and usage process of this utility model are as follows: When the user places the battery between the first pressure plate 6 and the second pressure plate 7, or when the starter motor 2 drives the first pressure plate 6 and the second pressure plate 7 to clamp and pressurize the battery through the bidirectional screw 3 and after the pressure sensor 5 detects the battery, the mirror protective plate 9 installed on the mounting plate 8 can protect the detection area of ​​the infrared distance sensor 4, so as to avoid damage to the detection area of ​​the infrared distance sensor 4 when the battery is removed and placed.

[0038] In the process of using the mirror protective plate 9 to protect the detection area of ​​the infrared distance sensor 4, the user can also insert the semi-ring connector 101 into the top of the mirror protective plate 9 so that the semi-ring protective sleeve 102 covers the top of the surface of the infrared distance sensor 4 detection area. Then, the side protective plate 103 can protect the front and back sides of the infrared distance sensor 4 detection area, further expanding the protection range and the protection effect.

[0039] During the transmission process between the first pressure plate 6 and the second pressure plate 7 via the bidirectional screw 3, the sliding cooperation between the limiting rod 111 and the limiting groove 112 can be used to limit the rotation of the first pressure plate 6 and the second pressure plate 7, preventing the first pressure plate 6 and the second pressure plate 7 from rotating directly during the driving process.

[0040] When the infrared distance sensor 4 experiences internal structural aging and damage, the user can first remove the semi-ring connector 101, then pull the infrared distance sensor 4 upwards to remove it from the elastic clamp 121. Next, insert the new infrared distance sensor 4 into the elastic clamp 121 and clamp it in place to facilitate quick installation of the new infrared distance sensor 4. At the same time, the two limiting rings 122 can limit the left and right movement of the installed infrared distance sensor 4 to ensure the stability of the infrared distance sensor 4 after installation.

[0041] In summary, the pressure testing device for this battery production, by setting up a mirror protective plate 9, can protect the detection point of the infrared distance sensor 4 by using the mirror protective plate 9 installed on the mounting plate 8. This prevents the infrared distance sensor 4 from being bumped and damaged when the battery is removed or placed. It solves the problem that the infrared distance sensor used to detect the distance between the two clamps lacks a protective structure, which leads to the infrared distance sensor's detection head being bumped and damaged when the user handles or prevents the battery from being handled.
