[0001] The present invention relates to the technical field of charger detection, and particularly to a detection device for the production of lithium battery chargers. Background Art

[0002] A lithium battery charger is a device specifically used to charge the lithium-ion battery of an electric vehicle. Lithium-ion batteries have relatively high requirements for chargers and require protection circuits. Therefore, lithium battery chargers usually have relatively high control precision and can charge lithium-ion batteries with constant current and constant voltage. Therefore, the industry needs to detect and test chargers.

[0003] In the Chinese patent literature database, the patent with the authorization announcement number CN220064148U discloses a detection device for the production of lithium battery chargers. By setting a test head and a test fixture to test multiple chargers simultaneously, the detection efficiency is improved. However, during actual operation, it is necessary to first insert the plug of the charger to be tested into the test fixture for fixation, and then push the entire test fixture to the lower part of the test head. The test head is pushed by a cylinder to insert into the plug for testing. Considerable time is still wasted during the loading and unloading process, reducing the work efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a detection device for the production of lithium battery chargers to solve the problems raised in the above background art.

A plurality of sockets are arranged on the test seat along its length direction, and both ends of the test seat are rotatably connected to the support frame through a rotating shaft. A limiting mechanism is arranged at the end of the test seat. A gear is fixed on the rotating shaft, and a rack meshing with it is horizontally slidably arranged below the gear. A push plate is fixed at the bottom end of the rack. The two positioning plates are fixedly connected by a plurality of connecting rods, and compression springs are sleeved at both ends of each connecting rod. A sliding hole matching with the connecting rod is arranged through the push plate, and a linear driving member for driving the two positioning plates to move horizontally synchronously is arranged on the support frame.

[0006] Further, the limiting mechanism includes a mounting plate fixed on the rotating shaft and a limiting post arranged on the mounting plate.

[0016] Please refer to Figures 1-4 , an embodiment provided by the present invention: a detection device for the production of lithium battery chargers, including a support frame 1, a test seat 2 arranged in the middle of the support frame 1, and two positioning plates 3 symmetrically arranged on both sides of the test seat 2. Specifically, the support frame 1 is a rectangular frame structure, and support legs 101 are arranged at the four corners of the bottom end of the support frame 1. During operation, the plug 12 of the lithium battery charger is detected, and the other end of the lithium battery charger can conveniently pass through the support frame 1 and be connected to the power supply downward.

[0017] The test seat 2 is a long strip structure, and five sockets 201 are arranged along its length direction. The test seat 2 is connected to the test device and can detect the connected lithium battery charger. Both ends of the test seat 2 are rotatably connected to the support frame 1 through rotating shafts 202. Limit mechanisms 11 are arranged at both ends of the test seat 2. The limit mechanism 11 includes a mounting plate 1101 fixed on the rotating shaft 202 and a limit post 1102 arranged on the mounting plate 1101. A through hole matching the rotating shaft 202 is penetrated through the support frame 1. The rotating shaft 202 passes through the through hole and extends to the outside of the support frame 1. The limit post 1102 is arranged on the side close to the support frame 1, and an arc-shaped limit sliding groove 1103 for accommodating the rotation of the limit post 1102 is arranged on the outer side wall of the support frame 1. The angle of the arc-shaped limit sliding groove 1103 is 180 degrees, which can play a limiting role, enabling the test seat 2 to only rotate 180 degrees, so that the sockets 201 on the test seat 2 can be sequentially flipped to face the two positioning plates 3, facilitating the subsequent plug-in detection.

[0018] Furthermore, the limit post 1102 is rotatably connected to the mounting plate 1101, so that the limit post 1102 and the arc-shaped limit sliding groove 1103 are in rolling connection, which can reduce wear.

[0019] Gears 6 are fixed on both of the two rotating shafts 202, and a rack 7 that meshes with the gears 6 is horizontally slidably arranged below the gears 6. The rack 7 abuts against the inner side wall of the support frame 1 and can be specifically connected by a slide rail. A push plate 8 is fixed at the bottom end of the rack 7. The push plate 8 connects the two racks 7, enabling the two racks 7 and the push plate 8 to slide horizontally synchronously. A gap is reserved between the push plate 8 and the test seat 2 to avoid affecting the rotation of the test seat 2. The two positioning plates 3 are fixedly connected by two connecting rods 9, and compression springs 10 are sleeved at both ends of the connecting rod 9. The compression springs 10 at both ends of the push are respectively located at both ends of the push plate 8. A sliding hole 801 that matches the connecting rod 9 is penetrated through the push plate 8. A linear drive member 5 for driving the two positioning plates 3 to move horizontally synchronously is arranged on the support frame 1. The linear drive member 5 can be specifically any one of a cylinder, an electric telescopic rod, etc. It is horizontally installed on the support frame 1, and the output end extends to the inside of the support frame 1 and is fixedly connected to any one of the positioning plates 3. By the telescopic movement of the linear drive member 5, the two positioning plates 3 and the connecting rod 9 are driven to slide horizontally synchronously inside the support frame 1. In order to improve the stability of the sliding, the two ends of the positioning plate 3 can be set to be slidably connected to the inner side wall of the support frame 1 through a slide rail. The positioning plate 3 is used to fix five plugs 12 to be detected at the same time. For the convenience of understanding, the two positioning plates 3 are respectively named as station one and station two. When initially operating, five plugs 12 to be detected are installed on station one, and the socket 201 on the test seat 2 faces station two horizontally. When the linear drive member 5 pushes station one to move horizontally towards the socket 201, the compression spring 10 first contacts the push plate 8, driving the push plate 8 and the rack 7 to move horizontally, and then driving the gear 6 and the test seat 2 to rotate. Under the limitation of the limiting mechanism 11, the test seat 2 can only rotate 180 degrees until the plug 12 is inserted into the socket 201. At this time, station two is pushed to the edge of the support frame 1, facilitating the staff to insert another group of plugs 12 to be detected. While the linear drive member 5 pushes the plug 12 on station one to separate from the socket 201, the plug 12 on station two is synchronously moved towards the side close to the test seat 2. The compression spring 10 on the side of station two pushes the push plate 8 and the rack 7 to move horizontally, driving the gear 6 and the test seat 2 to rotate 180 degrees, making the socket 201 face station two, facilitating the plug 12 to be inserted into it for detection. In this way, the loading and unloading and the detection are carried out simultaneously, reducing the waiting time.

[0020] Reference Figure 4, a plurality of positioning holes 301 that are each penetrated through the positioning plate 3 and are matched with the plugs 12 are provided, and the positioning holes 301 correspond to the sockets 201 one by one. Since a lithium battery charger generally has a front and a back, by providing the positioning holes 301, it is possible to prevent the plugs 12 from being inserted reversely and affecting the detection. A plurality of clamping mechanisms 4 corresponding to the positioning holes 301 one by one are provided on the side of the positioning plate 3 away from the test base 2. The clamping mechanism 4 includes two clamping plates 401 oppositely arranged on both sides of the positioning hole 301 and a tension spring 402 connecting the two clamping plates 401. The two clamping plates 401 can be horizontally slidably arranged on the side of the positioning plate 3 away from the test base 2 through slide rails. The clamping plates 401 can be provided with profiling grooves according to the shape of the plugs 12 to improve the clamping force and prevent the plugs 12 from detaching from the positioning plate 3 during the insertion process with the sockets 201.

[0021] Working principle: During operation, the five plugs 12 are respectively inserted into the positioning holes 301 on one side of the positioning plate 3. The two clamping plates 401 clamp and limit the plugs 12 under the elastic action of the tension spring 402. The linear drive member 5 pushes the positioning plate 3 to move towards the side close to the test base 2. First, the compression spring 10 on one side of the positioning plate 3 contacts the push plate 8, pushing the push plate 8 and the rack 7 to slide horizontally. The rack 7 meshes with the gear 6, and then drives the test base 2 to rotate 180 degrees, making the socket 201 face the plug 12. The limit posts 1102 at both ends of the test base 2 rotate in the arc-shaped limit sliding grooves 1103 to play a limiting role. Then, the plugs 12 are inserted into the sockets 201 for detection. At this time, the plugs 12 to be detected are installed on the other positioning plate 3. After the detection is completed, the linear drive member 5 pushes the positioning plate 3 to separate from the test base 2. The two positioning plates 3 move synchronously, and the installed positioning plate 3 on the other side also moves towards the side close to the test base 2 at the same time. Similarly, the compression spring 10 pushes the rack 7 and the push plate 8 to move horizontally, and then drives the test base 2 to flip 180 degrees, making the plugs 12 inserted into the sockets 201. In this way, the feeding and discharging and the detection are carried out simultaneously, improving the detection efficiency.
