Technical Field
[0001] This invention relates to the technical field of product testing, and in particular to a needle test structure for the surface of a battery positive electrode spring. Background Technology
[0002] With the development trend of consumer electronics products, manufacturers are imposing increasingly stringent testing requirements on their products. For example, some battery products have a B2B connector on one end and a spring structure on the other for connection and conduction. However, the spring in these batteries is generally located inside the product, at a certain depth from the outer surface of the end. Traditional testing structures typically use surface-to-surface testing to extract signals, but this method cannot reach the spring inside the product. During signal extraction and testing, this method results in poor signal stability and low testing accuracy because the probe cannot contact the positive electrode spring. If a simple structure could be designed that can press and insert a probe into the spring structure at the end of the product, and can be adapted to various depths and sizes of batteries by fine-tuning the structure, the above problems could be solved. Summary of the Invention

The probe is inserted into the product lower needle end on the product positioning seat through the guide port.
[0007] Furthermore, the pressing module includes an ejector cylinder, a pressing support frame, a pressing cylinder, and a pressing plate module. The pressing support frame slides with the upper surface of the support plate via several second slide rails. The ejector cylinder is disposed on the lower surface of the support plate, and the movable end of the ejector cylinder is connected to the lower surface of the pressing support frame. The pressing cylinder is disposed on the upper end of the pressing position of the pressing support frame. The pressing plate module is connected to the movable end of the pressing cylinder. The ejector cylinder and the pressing cylinder drive the pressing plate module to cooperate with the outer edge of the product and the interface end of the product, respectively.
[0008] Furthermore, the lower pressure plate module includes a lower pressure plate, an interface pressing block, and a product positioning block. The lower pressure plate is connected to the lower end of the lower pressure support frame via several linear bearings. The movable end of the lower pressure cylinder is connected to the upper surface of the lower pressure plate. The interface pressing block and the product positioning block are respectively disposed on both sides of the lower end surface of the lower pressure plate. The lower pressure cylinder drives the interface pressing block and the product positioning block to cooperate with the product interface end and the outer edge of the product, respectively.
[0009] Furthermore, floating springs are provided between the interface pressing block and the product positioning block and the lower pressure plate.
[0010] Furthermore, the lower end face of the pressure plate is provided with a plurality of positioning pins, and the base plate of the carrier plate is provided with a plurality of positioning holes.

Detailed Implementation
[0016] like Figures 1 to 6 As shown, in this embodiment, the present invention includes a support plate 1 and a pressing module 2, a carrier plate module 3, and a probe testing module 4 disposed on the support plate 1. The probe testing module 4 is disposed on one side of the carrier plate module 3, and the probe end of the probe testing module 4 is laterally inserted into the surface of the product spring on the carrier plate module 3. Several pressing ends of the pressing module 2 respectively cooperate with the outer edge of the product and the product interface end. Therefore, this application can solve the difficulty of not being able to contact the internal spring of the product. After the product is placed in the carrier plate module 3 for initial positioning, the pressing module 2 above presses down to achieve pressing, positioning, and conduction between the product itself and the B2B end. Then, the probe testing module 4 pushes laterally to extend the probe into the product, achieving docking and pressing with the spring structure, thereby achieving the effect of signal extraction. This method can adapt to products with different spring depths, has a simple structure, and high testing efficiency.
[0017] like Figures 1 to 3As shown, in this embodiment, the probe testing module 4 includes a support base plate 41, a side-push cylinder 42, a needle holder fixing frame 43, a probe plate 44, a probe mounting post 45, a probe 46, and a fine-tuning module 47. The support base plate 41 is disposed on the upper end surface of the support plate 1. The needle holder fixing frame 43 is slidably engaged with the support base plate 41 via a first slide rail 48. The side-push cylinder 42 is disposed on the lower end surface of the support plate 1, and the movable end of the side-push cylinder 42 is connected to the needle holder fixing frame 43. The probe plate 44 is connected to the fixed end of the needle holder fixing frame 43 via the fine-tuning module 47. The probe 46 is connected to the probe plate 44 via the probe mounting post 45. The side-push cylinder 42 drives the probe 46 to engage with the lower needle end of the product on the carrier plate module 3. Therefore, the probe 46 is set inside the probe mounting post 45, and the side-push cylinder 42 drives the needle holder fixing frame 43 to move laterally, so that the probe 46 passes through the carrier plate module 3 and extends into the product to contact the spring structure, thereby achieving docking and drawing out the quotient. The fine-tuning module 47 adopts a Z-axis slider and an X-axis slider sliding against each other, so that the probe 46 and the probe plate 44 can be adjusted in the X-axis and Y-axis directions, and the accuracy can be guaranteed even when repeated tests are performed.
[0018] like Figure 1 and Figure 4 As shown, in this embodiment, the carrier module 3 includes a carrier base plate 31, a product positioning seat 32, a probe guide seat 33, a needle block 34, and a flip-press module 35. The product positioning seat 32 and the needle block 34 are disposed on both sides of the middle of the upper end surface of the carrier base plate 31. The probe guide seat 33 is disposed on the upper end surface of the carrier base plate 31 near the product positioning seat 32. The probe guide seat 33 is provided with a guide port 36. The probe mounting post 45 cooperates with the guide port 36. The flip-press module 35 is disposed on the upper end surface of the carrier base plate 31 near the needle block 34 and drives the product interface end to cooperate with the needle block 34. The probe 46 is inserted into the product lower needle end on the product positioning seat 32 through the guide port 36. Therefore, the product positioning seat 32 performs initial positioning of the product, with the B2B end of the product positioned above the needle block 34. The flipping and pressing module 35 performs pre-pressing operation on the B2B end of the product to prevent displacement during subsequent pressing.
[0019] like Figure 5As shown, in this embodiment, the pressing module 2 includes an ejector cylinder 21, a pressing support frame 22, a pressing cylinder 23, and a pressing plate module 24. The pressing support frame 22 slides with the upper surface of the support plate 1 via several second slide rails 25. The ejector cylinder 21 is disposed on the lower surface of the support plate 1, and its movable end is connected to the lower surface of the pressing support frame 22. The pressing cylinder 23 is disposed on the upper end of the pressing position of the pressing support frame 22. The pressing plate module 24 is connected to the movable end of the pressing cylinder 23. The ejector cylinder 21 and the pressing cylinder 23 drive the pressing plate module 24 to cooperate with the outer edge of the product and the product interface end, respectively. Therefore, the pressing plate module 24 can achieve dual-axis adjustment, and after alignment, it presses down to perform vertical compression and fixation of the entire product, as well as pressing down and connecting the product's B2B end.
[0020] like Figure 6 As shown, in this embodiment, the lower pressure plate module 24 includes a lower pressure plate 241, an interface pressing block 242, and a product positioning block 243. The lower pressure plate 241 is connected to the lower end of the lower pressure support frame 22 via several linear bearings 244. The movable end of the lower pressure cylinder 23 is connected to the upper end face of the lower pressure plate 241. The interface pressing block 242 and the product positioning block 243 are respectively disposed on both sides of the lower end face of the lower pressure plate 241. The lower pressure cylinder 23 drives the interface pressing block 242 and the product positioning block 243 to cooperate with the product interface end and the outer edge of the product, respectively. Therefore, the linear bearings 244 ensure that the lower pressure plate 241 is pressed vertically without deviation. The product positioning block 243 has an arc groove at the pressing end, which can press the middle of the outer surface of the product in a contour manner. After the interface pressing block 242 realizes the product pressing and positioning, it presses down the B2B end of the product synchronously, so that it presses and connects with the needle block 34.
[0021] like Figure 5 and Figure 6 As shown, in this embodiment, floating springs are provided between the interface pressing block 242 and the product positioning block 243 and the lower pressure plate 241. Therefore, the floating springs provide a buffering effect during the mating pressing of the interface pressing block 242 and the product positioning block 243, resulting in more uniform pressing force and effectively preventing over-pressing of the product.
[0022] like Figure 4 and Figure 6As shown, in this embodiment, the lower end face of the pressure plate 241 is provided with a plurality of positioning pins 5, and the base plate 31 of the carrier plate is provided with a plurality of positioning holes 6. The plurality of positioning pins 5 and the plurality of positioning holes 6 cooperate with each other. The lower end face of the pressure plate 241 is also provided with a plurality of limiting posts 7, and the plurality of limiting posts 7 cooperate with the upper end face of the base plate 31 of the carrier plate. It can be seen that the plurality of positioning holes 6 provide a downward guiding function for the plurality of positioning pins 5, so as to improve the docking accuracy.
[0023] like Figure 4 As shown, in this embodiment, an optical fiber sensor 8 is provided on the upper surface of the carrier plate 31, and the optical fiber sensor 8 cooperates with the product sensing on the product positioning seat 32. Therefore, the optical fiber sensor 8 can sense whether the product is placed flat, and can provide timely feedback when the product shifts, preventing the pressing module 2 from damaging the product.
[0024] like Figure 4 As shown, in this embodiment, the flip-press module 35 includes a flip base 351 and a flip rod 352. The rotating end of the flip rod 352 is hinged to the rotating end of the flip base 351, and the pressing end of the flip rod 352 cooperates with the product interface end on the product positioning seat 32. Therefore, the flip rod 352 is used for product loading in its flipped-open state, and flipping down and pressing the B2B end of the product onto the needle block 34 achieves alignment pre-pressing.
[0025] like Figure 1 As shown, in this embodiment, a buffer 9 is provided on the upper surface of the support plate 1, and the buffer 9 cooperates with the pressing support frame 22. Therefore, the buffer 9 provides cushioning and prevents slippage when the pressing module 2 is reset.
[0026] The working principle of this invention is as follows: Before starting the equipment, the battery product is placed according to the placement direction of the product positioning seat 32, with the B2B end of the battery product positioned above the pin block 34. The flipping rod 352 is flipped and pressed down to align and pre-press the B2B end of the battery product with the pin block 34. The movable end of the ejection cylinder 21 extends, and the pressing support frame 22 slides to the pressing position. The pressing cylinder 23 drives the pressing plate 241 to descend, and the product positioning block 243 makes contact pre-press on the middle of the outer edge of the battery product. After further pressing, the interface pressing block 242 and the battery product... The B2B end of the battery is pressed down and inserted into the needle block 34 to achieve docking and conduction. After the pressing operation is completed, the movable end of the side push cylinder 42 extends out, and the probe mounting post 45 slides from the guide port 36 into the middle of the carrier plate 31. The probe 46 extends into the battery product at the same time. The head of the probe 46 contacts the spring structure of the battery product. After being compressed to a certain distance, the pressure is maintained, and the signal is started to be led out and tested. After the test is completed, all components are reset, the battery product to be tested is replaced, and the above steps are repeated to realize the alignment and needle insertion test on the surface of the positive electrode spring of the battery product.
[0027] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
