Description

Technical Field

[0001] This invention relates to the technical field of battery testing, and in particular to a battery holder testing device. Background Technology

[0002] With the continuous development of technology, various intelligent electronic devices are gradually entering people's lives. These devices are powered by electricity to operate various modules, enabling them to perform various functions, such as blowing air, emitting light, and generating heat. The realization of these functions requires the support of electricity. Currently, electronic devices on the market are mainly powered by external power sources or built-in batteries. Built-in batteries are mainly powered by connecting multiple battery cells through a battery holder, and then contacting various components through conductive structures such as battery holder contacts. During the battery production process, finished batteries need to be connected to power to measure various data such as voltage and battery life to check whether they meet the factory requirements. Currently, battery testing on the market mainly involves connecting the positive and negative contacts of the battery to the circuit for power-on testing. This method can only test the battery's voltage, current, and battery life, and cannot simultaneously test the battery holder contact structure. In daily use, the quality of the battery holder contacts will affect the service life. When the contacts have poor contact, unstable voltage or the contacts may not be able to return to their original position, resulting in disconnection. If a battery holder detection device with a simple structure that can accurately detect the pressing and energizing of the battery holder and simultaneously test the elasticity of the contact spring of the battery holder can be designed, the above problems can be solved. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a battery holder detection device with a simple structure that can realize accurate pressing and power-on detection of the battery holder and synchronous elasticity testing of the contact spring of the battery holder.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a base plate and a pressing assembly. The pressing assembly includes a base plate, an electromagnet module and a pressing block. The electromagnet module and the pressing block are respectively disposed at the upper and lower ends of the base plate. The electromagnet module drives the pressing block to cooperate with the battery holder on the base plate.

[0005] Furthermore, a lifting plate is provided between the pressure block and the substrate. The lifting plate is connected to the pressure block by several equal-height screws. The movable end of the electromagnet module is connected to the lifting plate. The electromagnet module drives the lifting plate and the pressure block to cooperate with the upper surface of the battery holder.

[0006] Furthermore, a pressure sensor is provided on the lower end face of the lifting plate, and the pressure sensor cooperates with the pressure block.

[0007] Furthermore, a plurality of guide rods are provided on the lower end face of the substrate, and the plurality of guide rods pass through the lifting plate and cooperate with the pressure block.

[0008] Furthermore, the battery holder cooperates with the limiting structure on the upper surface of the base plate, and the lower end of the pressure block is provided with a plurality of conductive pieces. The pressure block drives the plurality of conductive pieces to connect and conduct with the corresponding spring sheet structure on the battery holder.

[0009] Furthermore, the electromagnet module includes a fixed frame, an electromagnet, and a lifting rod module. The electromagnet is connected to the upper surface of the base plate through the fixed frame, and the electromagnet drives the movable end of the lifting rod module to cooperate with the lifting plate.

[0010] Furthermore, the base plate is connected to an external lifting mechanism via a lifting support plate.

[0011] Furthermore, a leak-proof sleeve is provided at the upper end of the substrate.

[0012] The beneficial effects of this utility model are: the bending deformation of several conductive pieces and their contact with the battery holder spring structure can realize the connection and conduction of the positive and negative electrodes, and test whether the positive and negative electrodes form a circuit to determine whether the positive and negative electrodes are well welded. At the same time, the multi-segment linkage pressing mechanism tests the continuous pressing of the battery holder spring structure, and the pressure curve is fed back by the pressure sensor. By combining various values, it is possible to accurately determine whether the battery holder is functioning well. The structure is simple, meets the requirements for simultaneous detection of multiple data of the battery, and is more efficient. Attached Figure Description

Detailed Implementation

[0014] like Figures 1 to 4As shown, in this embodiment, the present invention includes a base plate 1 and a pressing assembly 2. The pressing assembly 2 includes a base plate 3, an electromagnet module 4, and a pressing block 5. The electromagnet module 4 and the pressing block 5 are respectively disposed at the upper and lower ends of the base plate 3. The electromagnet module 4 drives the pressing block 5 to cooperate with the battery holder 6 on the base plate 1. Therefore, this application, while achieving positive and negative terminal connection of the battery holder, tests the elasticity of the spring contacts of the battery holder 6 through a multi-segment linkage pressing mechanism. The pressure sensor provides feedback on the pressure curve of the spring contacts of the battery holder 6. By combining various values, the functionality of the battery holder 6 can be accurately determined. The structure is simple, meets the requirements for simultaneous detection of multiple data of the battery holder 6, and is more efficient.

[0015] like Figures 1 to 3 As shown, in this embodiment, a lifting plate 7 is provided between the pressure block 5 and the base plate 3. The lifting plate 7 is connected to the pressure block 5 by several equal-height screws 8. The movable end of the electromagnet module 4 is connected to the lifting plate 7. The electromagnet module 4 drives the lifting plate 7 and the pressure block 5 to cooperate with the upper surface of the battery holder 6. Thus, the pressure block 5 contacts the upper surface of the battery holder 6 to achieve pre-pressure and lift, providing a downward stroke for the lifting plate 7. After the pre-pressure is completed, the descent of the lifting plate 7 drives the pressure block 5 to press down synchronously, so that the battery holder 6 can be stably pressed onto the base plate 1.

[0016] like Figures 1 to 3 As shown, in this embodiment, a pressure sensor 9 is provided on the lower end face of the lifting plate 7, and the pressure sensor 9 is inductively coupled with the pressure block 5. Therefore, the pressure sensor 9 is positioned between the lifting plate 7 and the pressure block 5, which effectively prevents inaccurate readings caused by uneven force distribution when directly contacting the conductive piece 11.

[0017] like Figure 2 As shown, in this embodiment, a plurality of guide rods 10 are provided on the lower end surface of the substrate 3, and the plurality of guide rods 10 pass through the lifting plate 7 and cooperate with the pressure block 5. It can be seen that the plurality of guide rods 10 play a guiding role, so that the lifting plate 7 can press more accurately and stably with the pressure block 5, and prevent the angle between the two from shifting during the pressing process, which would cause the value detected by the pressure sensor 9 to be inaccurate.

[0018] like Figure 2 and Figure 4As shown, in this embodiment, the battery holder 6 cooperates with the limiting structure on the upper surface of the base plate 1. The lower end of the pressure block 5 is provided with several conductive pieces 11. The pressure block 5 drives these conductive pieces 11 to connect and conduct with the corresponding spring contact structures on the battery holder 6. Therefore, the limiting structure on the base plate 1 can achieve rapid positioning of the battery holder 6. By having the corresponding conductive pieces 11 contact the positive and negative terminals of the battery holder 6, a circuit is tested to determine whether the positive and negative terminals are properly soldered.

[0019] like Figure 2 and Figure 3 As shown, in this embodiment, the electromagnet module 4 includes a fixing frame 41, an electromagnet 42, and a lifting rod module 43. The electromagnet 42 is connected to the upper surface of the base plate 3 through the fixing frame 41. The electromagnet 42 drives the movable end of the lifting rod module 43 to cooperate with the lifting plate 7. Therefore, the electromagnet 42 changes the magnetic field strength by changing the current, causing the movable end of the lifting rod module 43 to rise or fall, thereby achieving pressing or resetting.

[0020] like Figure 1 As shown, in this embodiment, the base plate 3 is connected to an external lifting mechanism via a lifting support plate 12. Therefore, the connection between the lifting support plate 12 and the external lifting mechanism or robotic arm enables alignment of the entire equipment with the product.

[0021] like Figure 1 As shown, in this embodiment, a leak-proof sleeve 13 is provided on the upper end of the substrate 3. Therefore, the leak-proof sleeve 13 can prevent leakage or other issues from occurring during the operation of the electromagnet module 4.

[0022] The working principle of this utility model is as follows: Before the equipment is started, the pressing component 2 is connected to the external lifting mechanism or robot arm through the lifting support plate 13. The battery holder 6 to be tested is placed in the contour structure on the base plate 1. The external lifting mechanism or robot arm drives the pressing component 2 to align with the battery holder 6 and descend so that several conductive pieces 11 make contact with the battery holder 6. The electromagnet 42 drives the movable end of the lifting rod module 43 to extend. The lifting plate 7 descends and drives the pressure block 5 to press the conductive pieces 11 to deform them, and drives the spring structure on the battery holder 6 to continuously press down. After the pressing operation is completed, the power-on test is performed. During this period, the pressure sensor 9 synchronously detects the bending pressure change of the spring structure of the battery holder 6 and compares it with the power-on data of the external detection mechanism. After the test is completed, each component is reset, the battery holder 6 to be tested is replaced, and the above steps are repeated to realize the synchronous detection of the power-on of the battery holder and the spring force of the spring.

[0023] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
