[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] like Figure 1-Figure 5 A battery testing tool is shown. In the specific implementation process, the controller 15, pressure sensor 5, test pen 4 and detection switch 2 included in the battery testing tool are all devices commonly used in the prior art, wherein the controller 15 can adopt a programmable logic controller PLC or a programmable automation controller PAC, the pressure sensor 5 is a differential pressure sensor 5, the working range is 0 to 10kPa, the model is MPX10DP, the detection switch 2 is an infrared sensor, the model is TCRT5000, and the test pen 4 is a conventional battery performance test pen 4. The controller 15, pressure sensor 5, test pen 4 and detection switch 2 involved in the battery testing tool provided by the present application can all work independently and realize their respective functions when working independently; in the battery testing tool provided by the present application, after the controller 15, pressure sensor 5, test pen 4 and detection switch 2 are connected according to the product manual, their respective functions are not affected by the connection, and the connected structure can realize all the functions of the battery testing tool provided by the present application.

[0026] What the present application intends to protect is the entire component structure of a battery testing tool and the connection relationship between each component device. After being combined and connected according to the component structure and connection relationship of a battery testing tool protected by the present application, all the functions of a battery testing tool provided by the present application can be realized.

[0027] refer to Figure 1-Figure 5As shown, a battery testing tool is mainly composed of a base 1, a pair of clamps 3 and a screw assembly, wherein the pair of clamps 3 are connected to the screw assembly, and the pair of clamps 3 stand on the base 1 in a relative manner. Driven by the screw assembly, the pair of clamps 3 can move relative to or away from each other on the base 1. The relative movement state represents clamping the battery and starting the battery performance test, while the away movement represents loosening the battery.

[0028] In this embodiment, the base 1 has a placement groove 101 located at the top and a groove 102 located at the bottom, which are connected by a guide groove 103. The length direction of the guide groove 103 is parallel to the long side of the base 1, wherein the placement groove 101 is a semicircular structure for placing cylindrical batteries, and the groove 102 is used to install the screw assembly.

[0029] Specifically, the base 1 is composed of a shell 104 and a bottom plate 105 connected to the bottom surface of the shell 104 by screws. At the same time, the shell 104 has a longitudinally penetrating mounting hole 106, and the detection switch 2 is fixed through the mounting hole 106. When the battery is placed in the placement slot 101, the detection switch 2, which serves as an infrared sensor, has its emitted light beam blocked, generates an action signal, and transmits it to the controller 15, which detects whether the battery is placed in the placement slot 101 through the detection switch 2.

[0030] In this embodiment, two clamps 3 stand in the placement groove 101 in a relatively movable manner, and each clamp 3 is provided with a through hole 302, the test pen 4 is inserted into the through hole 302 horizontally and movably, and the test end of the test pen 4 is allowed to protrude from the inner side of the clamp 3, and the test pen 4 preferentially contacts the battery with the pressure sensor 5 during the process of the clamp 3 clamping the battery, and a second mounting hole 301 is provided on one of the clamps 3 to fix the pressure sensor 5. It should be noted that the negative pole of the battery must correspond to the clamp 3 with the pressure sensor 5 to ensure that the flat negative pole of the battery contacts the pressure sensor 5. During the relative movement of the clamp 3, the battery first contacts the test pen 4 protruding from the clamp 3, and then the test pen 4 is pushed outward. When the pressure sensor 5 contacts the negative pole of the battery, the pressure sensor 5 generates a signal and transmits it to the controller 15, and the controller 15 makes a judgment to terminate the movement of the clamp 3.

[0031] At the same time, in order to ensure that the test pen 4 can return to its initial position after the test is completed, a guide cylinder 6 is arranged on the outer side of the splint 3, and a laterally movable disc 7 is arranged in the guide cylinder 6, and the disc 7 and the splint 3 are connected by a spring 8. Finally, the tail end of the test pen 4 is placed against the disc 7. During the movement of the test pen 4, its tail end pushes the disc 7 to move outward. At the same time, the spring 8 is stretched by the disc 7 to generate an elastic restoring force, and after the battery is removed, the elastic restoring force is released to push the test pen 4 to return to its initial position.

[0032] In addition, the test pen 4 is electrically connected to an external measuring device through a wire to transmit data to the measuring device.

[0033] The screw assembly is installed in the groove 102, and is mainly composed of a rotating shaft 9 with a pair of reverse threads 10, two movable blocks 11 corresponding to the reverse threads 10, a large gear 12, a small gear 13 and a motor 14, wherein the two ends of the rotating shaft 9 are rotatably set on the base 1 through bearings, and the two movable blocks 11 are correspondingly spirally connected to the reverse threads 10 of the rotating shaft 9. At the same time, the movable blocks 11 are upwardly inserted into the guide groove 103, and the large gear 12 and the small gear 13 are meshed with each other. Due to the battery-driven rotation of the key connection of the small gear 13, the large gear 12 is fixedly sleeved on the rotating shaft 9, producing a deceleration effect to drive the rotating shaft 9 to rotate. When the rotating shaft 9 rotates in the forward direction, the two movable blocks 11 move relative to each other along the axial direction of the rotating shaft 9, and then push the splint 3 to move relative to each other. Conversely, the two movable blocks 11 drive the two splints 3 to move in opposite directions.

[0034] The working principle of a battery testing tool provided by the utility model is as follows: by providing a base 1 with a placement groove 101, the battery to be tested can be placed in the placement groove 101, and the detection switch 2 on the base 1 detects that the battery falls into the placement groove 101, and feeds back the signal to the controller 15, and the controller 15 drives the screw rod assembly to move to promote the two clamps 3 to move relative to each other, so that the two test pens 4 are elastically pressed against the positive and negative poles of the battery until the pressure sensor 5 of the clamp 3 receives the pressure signal, and finally the battery performance test is completed. The utility model reduces manual intervention by introducing an automatic testing structure to improve the efficiency, accuracy and consistency of the battery testing process.
