[0002] The battery connector peel strength testing device is a specialized mechanical testing equipment. Its core function is to quantitatively measure the peel resistance mechanical properties of the connection interface between the battery connector and the cell terminal. However, most existing testing devices are designed to test battery connectors of fixed sizes. When encountering different sizes, it is difficult to adjust the clamping width, requiring different equipment for testing, which increases the overall testing cost. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model provides a battery connector peel strength testing device, which has the advantage of being able to easily clamp connectors of different sizes.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a battery connector peel strength testing device, comprising a base, a second sliding groove inside the base, a second slider slidably connected inside the second sliding groove, a lower clamp fixedly installed above the second slider, a support plate fixedly installed above the base, a cylinder fixedly installed on the rear side of the support plate, a connecting shaft fixedly installed at the output end of the cylinder, the side of the connecting shaft away from the support plate being fixedly connected to the lower clamp, and a fixing block fixedly installed above the base.
[0005] As a preferred technical solution of this utility model, a connecting platform is fixedly installed on the top of the base, a support block is fixedly installed on the outside of the connecting platform, a sliding groove is opened inside the support block, a slider is slidably connected inside the sliding groove, and a connecting plate is fixedly installed in front of the slider.
[0006] As a preferred embodiment of this utility model, a tension sensor is fixedly installed at the front of the connecting plate, and a connecting rod is fixedly installed at the bottom of the tension sensor.
[0007] As a preferred embodiment of this utility model, a fixing plate is fixedly installed at the bottom of the connecting rod, a connecting block is fixedly installed on the outer side of the fixing plate, a fixing shaft is fixedly installed on the connecting block, and an upper clamp is rotatably connected to the outer side of the fixing shaft.
[0008] As a preferred technical solution of this utility model, a silicone strip is fixedly installed at the bottom of the upper clamp, a second fixing plate is fixedly installed above the first fixing plate, a telescopic component is fixedly installed on the outside of the second fixing plate, a spring is sleeved on the outside of the telescopic component, and the spring compresses the side of the upper clamp near the connecting rod.
[0009] As a preferred embodiment of this utility model, a motor is fixedly installed at the end of the support block away from the connecting platform, and a lead screw is fixedly installed at the output end of the motor. The lead screw is inclined and meshes with the slider.
[0010] As a preferred embodiment of this utility model, a display screen is installed above the base.
[0011] As a preferred embodiment of this utility model, there are two upper clamps, both of which are located above the base and are distributed in opposite directions.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features a support plate fixedly installed above a base, a cylinder fixedly installed on the rear side of the support plate, and a connecting shaft fixedly installed at the output end of the cylinder. The side of the connecting shaft away from the support plate is fixedly connected to the lower clamp. A fixing block is also fixedly installed above the base, located in front of the lower clamp. When clamping a connector to be tested, the connector is first placed above the base. Then, the cylinder is activated to move the connecting shaft forward, which pushes the lower clamp forward. This causes the lower clamp to move through the sliding connection between slider two and slide groove two, bringing the front of the lower clamp into contact with the connector. Simultaneously, the connector is clamped by the fixing block, thus securing it. Because the lower clamp moves through the sliding connection between slider two and slide groove two, it can effectively clamp connectors of different sizes, achieving the effect of clamping connectors of varying dimensions.
[0013] 2. This utility model features an upper clamp rotatably connected to the outside of a fixed shaft. A silicone strip is fixedly installed at the bottom of the upper clamp. A second fixed plate is fixedly installed above the first fixed plate. A telescopic component is fixedly installed on the outside of the second fixed plate. A spring is sleeved on the outside of the telescopic component, and the spring presses against the side of the upper clamp near the connecting rod. When peeling is required, the film on the surface of the connector is first slightly torn. Then, the upper clamp is pressed towards the side near the second fixed plate, opening the bottom of the upper clamp. The slightly torn film is then placed at the bottom of the upper clamp. The upper clamp is released, and the spring provides elasticity to push the upper clamp away from the connecting rod, pushing the bottom of the upper clamp towards the connecting rod. At this time, the silicone strip at the bottom of the upper clamp clamps the film, achieving a convenient pulling effect. Simultaneously, the increased friction between the silicone strip and the film makes the silicone strip clamp the film more firmly, preventing it from falling off. Attached Figure Description

[0016] 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.
[0017] like Figures 1 to 5 As shown, this utility model provides a battery connector peel strength testing device, including a base 1, a second sliding groove 27 is provided inside the base 1, a second slider 17 is slidably connected inside the second sliding groove 27, a lower clamp 18 is fixedly installed above the second slider 17, a support plate 19 is fixedly installed above the base 1, a cylinder 20 is fixedly installed on the rear side of the support plate 19, a connecting shaft 21 is fixedly installed at the output end of the cylinder 20, the side of the connecting shaft 21 away from the support plate 19 is fixedly connected to the lower clamp 18, and a fixing block 22 is fixedly installed above the base 1.
[0018] The fixing block 22 is located in front of the lower clamp 18. When it is necessary to clamp the connector to be tested, the connector is first placed above the base 1. At this time, the cylinder 20 is started to drive the connecting shaft 21 to move forward. The connecting shaft 21 will push the lower clamp 18 forward, so that the lower clamp 18 moves through the sliding connection between the slider 27 and the slide groove 27, so that the front side of the lower clamp 18 contacts the connector. At the same time, the connector is clamped by the fixing action of the fixing block 22, so that the connector is fixed. Since the lower clamp 18 moves through the sliding connection between the slider 27 and the slide groove 27, it can effectively clamp connectors of different sizes, so as to achieve the effect of clamping connectors of different sizes.
[0019] Among them, a connecting platform 2 is fixedly installed on the top of the base 1, a support block 3 is fixedly installed on the outside of the connecting platform 2, a sliding groove 4 is opened inside the support block 3, a slider 5 is slidably connected inside the sliding groove 4, a connecting plate 6 is fixedly installed in front of the slider 5, a tension sensor 7 is fixedly installed in front of the connecting plate 6, and a connecting rod 8 is fixedly installed at the bottom of the tension sensor 7.
[0020] The connecting plate 6 moves through the sliding connection between the slider 5 and the slide groove 4, causing the connecting plate 6 to raise the height of the tension sensor 7, thereby simulating the effect of a person tearing the film, and the resulting tension is recorded by the tension sensor 7 to achieve the detection effect.
[0021] Among them, a fixing plate 9 is fixedly installed at the bottom of the connecting rod 8, a connecting block 10 is fixedly installed on the outside of the fixing plate 9, a fixing shaft 11 is fixedly installed on the connecting block 10, an upper clamp 12 is rotatably connected to the outside of the fixing shaft 11, a silicone strip 13 is fixedly installed at the bottom of the upper clamp 12, a fixing plate 14 is fixedly installed above the fixing plate 9, a telescopic component 15 is fixedly installed on the outside of the fixing plate 14, a spring 16 is sleeved on the outside of the telescopic component 15, and the spring 16 presses the side of the upper clamp 12 close to the connecting rod 8.
[0022] When peeling is required, first slightly tear the film on the surface of the connector. Then, press the upper clamp 12 towards the side closer to the fixing plate 14 to open the bottom of the upper clamp 12. Place the slightly torn film at the bottom of the upper clamp 12 and release the upper clamp 12. The spring 16 will provide elasticity to push the upper clamp 12 away from the connecting rod 8, and push the bottom of the upper clamp 12 towards the connecting rod 8. At this time, the silicone strip 13 at the bottom of the upper clamp 12 will clamp the film to achieve a convenient pulling effect. At the same time, the friction between the material of the silicone strip 13 and the film will increase, making the silicone strip 13 clamp the film more firmly and preventing it from falling off.
[0023] Among them, a motor 25 is fixedly installed at the end of the support block 3 away from the connecting platform 2, and a lead screw 26 is fixedly installed at the output end of the motor 25. The lead screw 26 meshes with the slider 5.
[0024] When the motor 25 is started, it will drive the lead screw 26 to rotate. At this time, the motor 25 will be controlled by the controller to achieve uniform rotation. During the process of the lead screw 26 engaging with the slider 5, the connecting plate 6 will drive the tension sensor 7 to rise at a uniform speed, thus achieving a stable force effect.
[0025] The base 1 has a display screen 24 mounted on top, and the tension sensor 7 is electrically connected to an output line 23, which is connected to the controller.
[0026] When the tension sensor 7 drives the fixed plate 9 to be stretched at a constant speed through the connecting rod 8 at the bottom, the tension sensed by the tension sensor 7 will be transmitted to the inside of the controller through the output line 23. After data processing, it will be displayed on the display screen 24, making the detection more intuitive.
[0027] There are two upper clamps 12, both of which are located above the base 1 and are distributed in opposite directions.
[0028] The main function of the two upper clamps 12 is to be squeezed by the spring 16, so that the top of the two upper clamps 12 is pushed to achieve the effect of clamping at any time, while making clamping simpler and improving work efficiency.
[0029] Working principle and usage process of this utility model: First, a support plate 19 is fixedly installed above the base 1. A cylinder 20 is fixedly installed on the rear side of the support plate 19. A connecting shaft 21 is fixedly installed at the output end of the cylinder 20. The side of the connecting shaft 21 away from the support plate 19 is fixedly connected to the lower clamp 18. At the same time, a fixing block 22 is fixedly installed above the base 1. The fixing block 22 is located in front of the lower clamp 18. When it is necessary to clamp the connector to be tested, the connector is first placed above the base 1. Then, the cylinder 20 is started to drive the connecting shaft 21 to move forward. The connecting shaft 21 will push the lower clamp 18 forward, so that the lower clamp 18 moves through the sliding connection between the slider 27 and the slide groove 27, so that the front side of the lower clamp 18 contacts the connector. At the same time, the connector is clamped by the fixing action of the fixing block 22, so that the connector is fixed. Secondly, an upper clamp 12 is rotatably connected to the outside of the fixed shaft 11. A silicone strip 13 is fixedly installed at the bottom of the upper clamp 12. A second fixed plate 14 is fixedly installed above the first fixed plate 9. A telescopic component 15 is fixedly installed on the outside of the second fixed plate 14. A spring 16 is sleeved on the outside of the telescopic component 15. The spring 16 presses the side of the upper clamp 12 near the connecting rod 8. When peeling, the film on the surface of the connector is slightly torn. At this time, the upper clamp 12 is pressed towards the side near the second fixed plate 14, so that the bottom of the upper clamp 12 is opened. Then, the slightly torn film is placed at the bottom of the upper clamp 12. The upper clamp 12 is released, so that the spring 16 provides elastic force to push the upper clamp 12 away from the connecting rod 8, so that the bottom of the upper clamp 12 is pushed towards the side near the connecting rod 8. At this time, the silicone strip 13 at the bottom of the upper clamp 12 will clamp the film to achieve the effect of easy pulling. At the same time, the friction between the material of silicone strip 13 and the film will increase, thus making the silicone strip 13 clamp the film more firmly and preventing it from falling off. Finally, starting the motor 25 will drive the lead screw 26 to rotate. At this time, the motor 25 will be controlled by the controller to rotate at a constant speed. During the process of the lead screw 26 engaging with the slider 5, the connecting plate 6 will drive the tension sensor 7 to rise at a constant speed, thereby simulating the effect of a person tearing the film. The tension sensed by the tension sensor 7 will be transmitted to the inside of the controller through the output line 23. After data processing, it will be displayed on the display screen 24, making the detection more intuitive.
