Description

Technical Field

[0001] This utility model relates to a detection device, specifically a lithium-ion battery electrode adaptive contact detection device, belonging to the field of lithium-ion battery detection technology. Background Technology

[0002] The primary purpose of testing lithium-ion batteries is to comprehensively evaluate their performance, safety, and reliability, ensuring stable and safe operation under various conditions. Testing allows for the acquisition of key parameters such as battery capacity, internal resistance, cycle life, and charge / discharge efficiency. Lithium-ion battery testing robots acquire various battery data in real time. These sensors convert physical quantities into electrical signals, which are then transmitted to the robot's control system. By analyzing the battery's charge / discharge curves, monitoring changes in internal resistance, and comparing historical data, the robot determines the battery's health status. Some intelligent monitoring robots also employ machine learning or deep learning algorithms to continuously optimize the accuracy of health status estimation.

[0003] Currently, when inspection robots perform contact inspections on lithium-ion batteries, they generally face a key problem: the design of their contact inspection mechanisms is often difficult to flexibly adapt to lithium-ion batteries of different specifications. In particular, when there are differences in the spacing between the terminals of lithium-ion batteries, traditional contact inspection mechanisms lack sufficient adjustment range or adaptive capability, and cannot quickly and accurately adapt to these changes. This leads to the need for frequent manual adjustment or replacement of inspection components during the inspection process, which seriously affects the inspection efficiency and continuity. In some cases, poor contact may even lead to inaccurate inspection data, making it difficult to meet the inspection needs of large-scale, high-efficiency lithium-ion battery production. To address this, an adaptive contact inspection device for lithium-ion battery terminals is proposed. 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] Example

[0025] Please see Figures 1-4 This utility model provides a technical solution: an adaptive contact detection device for lithium-ion battery terminals, including a robotic arm 32, with a contact detection component 101 at the end of the robotic arm 32. The contact detection component 101 includes a detection seat 12, an adjustment motor 13, a positioning camera 14, a double-ended lead screw 15, two sliders 16, two slide grooves 17, a spring 18, four guide rods 19, a mounting plate 20, and a detection rod 21.

[0026] Two slide grooves 17 are symmetrically opened on the front surface of the detection seat 12. The slider 16 is slidably connected to the inner side wall of the slide groove 17. The slide groove 17 is used to limit the position of the slider 16. The two sliders 16 are symmetrically threaded to the outer side wall of the double-ended lead screw 15. The adjusting motor 13 is installed on one side of the detection seat 12. The adjusting motor 13 drives the double-ended lead screw 15 to rotate. When the double-ended lead screw 15 rotates, it drives the two sliders 16 through the threads on its surface, so that the two sliders 16 can move closer to each other or further away from each other, thereby adjusting the position of the two detection rods 21.

[0027] The rear ends of the four guide rods 19 are symmetrically fixed to the front surface of the slider 16. The mounting plate 20 is slidably connected to the outer side wall of the four guide rods 19. The position of the mounting plate 20 can be defined by the guide rods 19. The detection rod 21 is fixedly connected to the inside of the mounting plate 20. The position of the detection rod 21 can be defined by the mounting plate 20. When the detection rod 21 contacts the lithium-ion battery terminal, the detection rod 21 can adaptively slide along the guide rods 19.

[0028] The front end of the detection rod 21 is provided with a tapered contact portion 22. The detection rod 21 is made of copper and can be in contact with the lithium-ion battery terminal. Therefore, during the test, the detection rod 21 can contact the lithium-ion battery terminal through the tapered contact portion 22, which increases the contact range of the detection rod 21.

[0029] In this embodiment, specifically: the double-ended lead screw 15 is rotatably connected to the inside of the detection seat 12, and one end of the double-ended lead screw 15 is fixedly connected to the output shaft of the adjusting motor 13. When the adjusting motor 13 is working, the double-ended lead screw 15 drives the two sliders 16, thereby adjusting the distance between the two detection rods 21.

[0030] In this embodiment, specifically: the spring 18 is sleeved on the outer side wall of the guide rod 19, one end of the spring 18 abuts against the rear surface of the mounting plate 20, and the other end of the spring 18 abuts against the front surface of the slider 16. The spring 18 can play a buffering role to prevent the detection rod 21 from colliding with the lithium-ion battery terminal, thus ensuring safety during the detection process.

[0031] When the detection rod 21 contacts the lithium-ion battery terminal, the detection rod 21 is subjected to the reverse thrust of the lithium-ion battery terminal. The detection rod 21 drives the mounting plate 20, and the mounting plate 20 slides along the guide rod 19. At this time, the spring 18 is compressed.

[0032] Under the force of spring 18, the detection rod 21 can maintain contact with the lithium-ion battery terminal, thus ensuring the continuity of detection.

[0033] In this embodiment, specifically: the conical contact part 22 and the detection rod 21 are an integral structure, both made of copper, and have good conductivity.

[0034] In this embodiment, specifically: the positioning camera 14 is installed on the front surface of the detection base 12, and the positioning camera 14 is located between the two detection rods 21;

[0035] The positioning camera 14 is used to acquire high-definition images of the lithium-ion battery terminals from multiple angles, obtaining key visual information such as the terminal outline and edges. The image data is transmitted to the central processing unit in real time in the form of digital signals. The central processing unit uses image recognition algorithms, including edge detection and feature point extraction, to accurately identify the terminal position. Through pixel calculation and coordinate system transformation, combined with the pre-calibrated actual size ratio, the actual distance between the lithium-ion battery terminals is calculated. Then, based on the robot's own coordinate system, the corresponding precise position coordinates are generated. Subsequently, the central processing unit compares the terminal spacing data with the current spacing of the detection rod 21 according to the calculation results, generates control commands according to the preset control logic, and sends them to the adjustment motor 13. After receiving the command, the adjustment motor 13 drives the double-headed lead screw 15 to rotate. At this time, the distance between the two detection rods 21 can be adjusted, thereby realizing the adaptive adjustment of the detection rods 21 and ensuring the smooth progress of subsequent detection work.

[0036] In this embodiment, specifically: a connecting seat 11 is fixedly connected to the rear surface of the detection seat 12, the detection seat 12 is installed on the top of the robotic arm 32 through the connecting seat 11, and a robot walking base 31 is installed at the bottom of the robotic arm 32. Thus, through the cooperation of the robot walking base 31 and the robotic arm 32, lithium-ion batteries at different positions can be detected.

[0037] Both the robot walking base 31 and the robotic arm 32 are existing technologies, so their internal structure and working principle will not be described in detail.

[0038] In this embodiment, specifically: a control cabinet 33 is installed on the upper surface of the robot walking base 31. The control cabinet 33 integrates a robot control system, a central processing unit, and a battery charge and discharge tester. The detection rod 21 is connected to the battery charge and discharge tester through a wire.

[0039] In terms of working principle or structural principle, during use, the entire device moves to the position corresponding to the lithium-ion battery via the robot walking base 31. Then, the robotic arm 32 drives the detection seat 12 to move. At this time, the positioning camera 14 acquires high-definition images of the lithium-ion battery terminals from multiple angles. Then, the central processing unit calculates the actual distance between the lithium-ion battery terminals, generates control commands, and sends them to the adjustment motor 13. The adjustment motor 13 drives the double-ended lead screw 15 to rotate. When the double-ended lead screw 15 rotates, it drives the two sliders 16 through the threads on its surface, which can make the two sliders 16 move closer or further apart. At this time, the distance between the two detection rods 21 can be adjusted, thereby realizing the adaptive adjustment of the detection rods 21 and ensuring the smooth progress of subsequent testing. Then, the robotic arm 32 drives the detection rods 21 to contact the lithium-ion battery terminals. Since the detection rods 21 are connected to the battery charge and discharge tester, the battery charge and discharge tester can obtain key parameters such as battery capacity, internal resistance, cycle life, and charge and discharge efficiency, thereby realizing the testing of lithium-ion batteries.

[0040] Compared with the prior art, this utility model can automatically adjust the distance between the two detection rods 21 by setting the contact detection component 101, eliminating the need for frequent manual adjustment or replacement of detection components, thus improving detection efficiency and continuity. Moreover, through the cooperation of the spring 18, mounting plate 20, guide rod 19 and other structures, collisions between the detection rods 21 and the lithium-ion battery terminals can be avoided during the detection process, ensuring safety during the detection process.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
