Description

Technical Field

[0001] The utility model is applied to the technical field of battery protection board detection, and particularly relates to a battery protection board test fixture. Background Art

[0002] With the continuous development of technology, the component integration and intelligence of various electronic products are getting higher and higher. With the improvement of the component integration of electronic products, each component requires a stable power supply for independent power supply, and the performance requirements for product batteries and battery protection boards are also constantly increasing. The electronic protection board is usually set as a multi-segment deflection structure, so that the battery protection board can be installed between each component and the battery, thereby reducing the size of the electronic product. After the battery protection board is produced, it needs to be powered on and detected to ensure that the battery protection board can meet the factory use requirements. At present, the battery protection board is mainly manually installed on the carrier, the carrier is transported to the detection machine, and then the external detection module is manually connected to the connection end of the battery protection board for power-on detection. This method has a high labor cost, a low alignment accuracy through manual connection, and is easy to scratch the battery protection board during the connection process, thereby reducing the product yield. Moreover, manual operation cannot be carried out in the extreme environment of -20°C to 80°C. Or the carrier loaded with the battery protection board is transported to the detection machine through the conveying mechanism, and then the manipulator cooperates with the positioning mechanism for positioning and connection and power-on. This method can ensure the connection accuracy, but when multiple-point detection is required, the needles cannot be inserted simultaneously, and multiple stations are required for independent detection, which requires a large detection site and cannot detect multiple groups of products simultaneously, resulting in low efficiency and not meeting the requirements of high-efficiency production of enterprises. If a battery protection board test fixture with a simple structure, accurate positioning, a large number of detections, and capable of simultaneously performing multi-point needle insertion on the battery protection board can be designed, the above problems can be solved.

The lower end of the tail needle board 241 is provided with a plurality of adapter copper posts 248. The upper ends of the plurality of adapter copper posts 248 are connected and conductively connected to the lower end surface of the WIB adapter board 242.

The pressing ends of the plurality of SIP press rods 324 are matched with the upper ends of the 4SIP ends of the products on the corresponding fixed insert block 12. Thus, it can be seen that the upper pressure plate 31 drives the SIP press rods 324 to contact and pre-press the upper ends of the 4SIP ends of the products, and then drives the products 4 to descend and be connected and conductively connected to the CELL probe module 23.

The pressing end of the B2B press head 332 cooperates with the upper end of the 4B2B end of the product on the corresponding fixed insert block 12. It can be seen that the upper pressure plate 31 drives the B2B press head 332 to contact and pre-press the upper end of the product 4B2N end, and then drives the product 4 to descend and be connected and conducted with the B2B probe module 22. The plurality of fourth equal-height screws 333 and the plurality of fourth floating springs 334 provide a buffering effect.

The plurality of limit guide sleeves 13 respectively cooperate with the rough positioning pin 37 and the fine positioning pin 38, and the plurality of positioning holes 14 cooperate with the plurality of anti-fooling posts 39. It can be seen that the upper cover plate 34 is used to protect the SIP press head module 32 and the B2B press head module 33, and is also used as a handle during handling. The rough positioning pin 37, the fine positioning pin 38 and the plurality of anti-fooling posts 39 can ensure the positioning accuracy.

[0033] As Figure 2 and 7 shown, in this embodiment, the needle plate 21 is provided with a plurality of linear bearings 5.

An insulating insert 18 is further provided on the lower end surface of the fixed insert 12. Thus, it can be seen that the 12 groups of fixed inserts 12 are arranged on the 12 groups of insert limiting grooves 15 to achieve the preliminary fixation of the carrier. The product limiting groove 17 is in limiting cooperation with the product 4 to achieve the preliminary positioning of the product. The probe ends of the B2B probe module 22 and the probe ends of the CELL probe module 23 pass through the probe through-holes 16 and are connected and conducted with the product 4 through the connection through-holes at the positions corresponding to the connection ends of the product 4 on the product limiting groove 17.

[0035] As Figure 5 shown, in this embodiment, the carrier board 11 is further provided with a QR code card slot 9 and an anti-fooling mark 10. Thus, it can be seen that the QR code card slot 9 and the anti-fooling mark 10 can prevent misoperation of loading and unloading.
