Description

Technical Field

[0001] This utility model relates to the technical field of fixtures for battery testing, and in particular to a fixture for testing small batteries. Background Technology

[0002] With the rapid development of portable electronic devices and the new energy industry, batteries, as core energy components, directly impact the safety and user experience of end products. Therefore, performance testing is crucial during battery production to ensure that key parameters such as voltage, internal resistance, and charge / discharge characteristics meet design requirements. However, current testing methods typically require connecting test terminals to the positive and negative terminals of the battery. Due to differences in the structural design of different battery models, the arrangement of contact terminals varies; for example, some battery terminals are located on a horizontal surface, while others may be positioned on a vertical side. Current testing devices mostly employ fixed terminal designs, meaning the test terminals are usually only compatible with a single type of battery, significantly limiting their application scenarios.

Detailed Implementation

[0017] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0018] Example: A fixture for testing small batteries, combined with Figures 1-4 As shown, it includes: a base 1; a mounting bracket 2 fixedly installed at the rear of the base 1; an electric push rod 3 fixedly installed on the mounting bracket 2, the end of the electric push rod 3 being vertically displaced; a detector 4 fixedly installed on the mounting bracket 2, the detector 4 being electrically connected to the electric push rod 3 to control the extension and retraction of its end; a mounting plate 5 fixedly installed on the end of the electric push rod 3; a first electric slide rail 6 fixedly installed on the mounting plate 5, the detector 4 being electrically connected to the first electric slide rail 6 to control the operation of the first electric slide rail 6; and two mounting arms 7 fixedly installed on the control end of the first electric slide rail 6, the operation of the first electric slide rail 6 controlling the mounting arms 7. The device includes: a horizontal displacement device; a mounting column 8 fixedly mounted on the mounting arm 7; a first adjusting column 9 rotatably mounted on the mounting column 8; a second adjusting column 11 rotatably mounted on the first adjusting column 9, the rotation surface of the second adjusting column 11 being perpendicular to the rotation surface of the first adjusting column 9; a detection terminal 13 fixedly mounted on the second adjusting column 11 and connected to the contact terminal of the battery, the second adjusting column 11 having a wire groove 14, the detection terminal 13 being electrically connected to the detector 4 and having wires running in the wire groove 14; and protrusions 22 fixedly mounted on the first adjusting column 9 and the second adjusting column 11, which are used to increase friction to facilitate the rotation of the first adjusting column 9 and the second adjusting column 11.

[0019] When using this fixture to test batteries, the operating procedure is as follows: First, place the battery to be tested on the base 1. Adjust the orientation of the testing terminal 13 in this fixture according to the specific position of the battery contact terminals. If the contact terminals are on a horizontal plane, simply rotate the second adjusting column 11 90 degrees to make it vertical and the contact surface of the testing terminal 13 facing down. If the contact terminals are on a vertical plane and facing backward, first rotate the second adjusting column 11 90 degrees to make the contact surface of the testing terminal 13 facing down, and then rotate the first adjusting column 9 90 degrees to make the second adjusting column 11 horizontal and the testing surface of the testing terminal 13 facing backward. Adjustments in other directions can be made by combining the above operations to achieve omnidirectional free adjustment of the testing terminal 13, so that this fixture can be adapted to batteries with different contact terminal structures.

[0020] After adjusting the test terminal 13, batch testing of batteries of the same batch and structure can be carried out: place the battery on the base 1, drive the mounting plate 5 to move down by controlling the electric push rod 3, and control the first electric slide rail 6 to move the mounting arm 7 so that the adjusted test terminal 13 accurately connects with the contact terminal of the battery, and the testing process can be started conveniently and quickly; after the test is completed, control the electric push rod 3 and the first electric slide rail 6 to remove the test terminal 13 so as to replace the new battery, and repeat the above operation to complete the next round of testing.

[0021] Combination Figures 1-4 As shown, this fixture also includes: magnets 10 fixedly mounted on the mounting column 8 and the first adjusting column 9 respectively; and iron blocks 12 fixedly mounted on the first adjusting column 9 and the second adjusting column 11 respectively. The magnets 10 on the mounting column 8 and the iron blocks 12 on the first adjusting column 9 are magnetically attracted to each other, and the magnets 10 on the first adjusting column 9 and the iron blocks 12 on the second adjusting column 11 are also magnetically attracted to each other. Through the magnetic attraction between the magnets 10 and the iron blocks 12, the relative positions of the first adjusting column 9 and the second adjusting column 11 after adjustment can be precisely locked. This structural design effectively ensures the positional accuracy of the detection terminal 13 after adjustment, preventing the detection terminal 13 from shifting due to frequent contact with the battery during the detection process, thereby reducing the resulting detection error and ensuring the stability and accuracy of the fixture's detection work.

[0022] Combination Figure 1 and Figure 5As shown, this fixture also includes: a positioning plate 15 fixedly mounted on the base 1; a second electric slide rail 16 fixedly mounted on the base 1; an adjustment plate 17 fixedly mounted on the control end of the second electric slide rail 16, the adjustment plate 17 being located behind the positioning plate 15; and a roller 21 rotatably mounted on the base 1, the roller 21 being located between the positioning plate 15 and the adjustment plate 17. When the battery is placed on the base 1, so that the battery is between the positioning plate 15 and the adjustment plate 17, the second electric slide rail 16 is activated, controlling the adjustment plate 17 to move and reduce the distance between it and the positioning plate 15. By controlling the relative position of the positioning plate 15 and the adjustment plate 17, the battery can be quickly aligned and accurately positioned. Therefore, during the adjustment stage of the detection terminal 13, after adjustment based on the battery at this positioning position, subsequent batteries of the same specification only need to be placed on the base 1 in the same way and positioned to quickly and accurately cooperate with the adjusted detection terminal 13, greatly improving the detection efficiency of this fixture.

[0023] Combination Figure 1 and Figure 5 As shown, this fixture also includes: a buffer plate 18 slidably mounted on the adjusting plate 17; a spring 19 fixedly mounted between the buffer plate 18 and the adjusting plate 17; a protective pad 20 fixedly mounted on the buffer plate 18 and the positioning plate 15, the protective pad 20 being located on the sides of both that contact the battery; and a protective sleeve 23 fitted over the spring 19 for protection. When the adjusting plate 17 and the positioning plate 15 are used to position the battery, the buffer plate 18 will contact the battery before the adjusting plate 17. The elasticity of the spring 19 buffers the excessive displacement of the adjusting plate 17, thereby preventing damage caused by the positioning plate 15 and the adjusting plate 17 excessively clamping the battery due to the untimely control of the second electric slide rail 16; the protective pad 20 can further prevent the positioning plate 15 and the adjusting plate 17 from directly contacting the battery and causing pinching damage; the protective sleeve 23 can effectively protect the spring 19, reducing the corrosion and wear of the external environment, thereby extending the service life of the spring 19.
