Description

Technical Field

[0001] This utility model relates to the field of electronic component testing technology, and in particular to a side-insertion module for PCB gold finger testing. Background Technology

[0002] When testing components on a PCB board, the gold fingers of the PCB board need to be inserted into the slots of the connector and powered on for inspection. Currently, manufacturers generally use manual insertion and removal, which is not only inefficient but also poses a risk of electric shock in high-voltage testing environments. Some manufacturers use insertion / removal devices, which use cylinders to power the insertion and removal of single or multiple gold fingers. However, this type is typically suitable for PCBs with vertical insertion / removal designs. For PCBs with side-insertion modules, it is still necessary to manually push the adapter card and insert and remove the gold fingers one-to-one, which cannot meet production testing efficiency requirements. Furthermore, in existing insertion / removal devices, the connection between the adapter card and the driver is usually rigid. When the insertion point is misaligned and cannot be fully inserted, the gold fingers or the adapter card can be easily damaged, resulting in a low test error tolerance. 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 side-insertion module for PCB gold finger testing that has a simple structure, can adapt to the detection of multiple sets of side-insertion gold fingers, improves the detection efficiency, and has a shock absorption function to effectively improve the service life of the equipment and the test fault tolerance.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a drive unit, a guide rail, a push plate, and several side insertion components. One end of the push plate is connected to the drive unit and slides with the guide rail through several sliding blocks. Several side insertion components are detachably installed on the lower surface of the push plate. Each side insertion component includes a push block, a horizontal clamp, and an adapter card. The horizontal clamp holds the adapter card and is set on the push block through a floating unit.

[0005] Furthermore, the top of the push block is connected to the push plate by a hexagonal screw. The floating unit includes a floating block, several equal-height screws, and a buffer spring. The floating block is connected to the push block by several equal-height screws. A stepped hole is opened in the push block at the position corresponding to several equal-height screws. The buffer spring is sleeved on the equal-height screw and located in the stepped hole.

[0006] Furthermore, the horizontal clamp includes horizontal clamping blocks symmetrically arranged on the left and right end faces of the floating block. The horizontal clamping blocks are connected to the floating block by adjusting screws, and the setting distance between the two horizontal clamping blocks is adjustable.

[0007] Furthermore, the lower end of the inner side of the horizontal clamping block is provided with a slot that is compatible with the adapter card, and a clamping protrusion is provided in the middle of the slot.

[0008] Furthermore, the drive unit employs a cylinder, an electric push rod, or a hydraulic push rod.

[0009] Finally, the guide rail includes two sets of symmetrically arranged guide rails, with guide rail pads connected to the bottom of the guide rails. The push plate spans across the two sets of guide rails, and the push plate is slidably connected to each set of guide rails through two sets of sliding blocks.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model improves upon the problem that existing PCB board gold finger detection plug-in / plug-out devices cannot handle side-plug modules. The drive unit provides stable insertion and removal power to the push plate, improving testing efficiency. The symmetrical arrangement of the dual slide rails ensures the radial movement stability of the push plate. The floating unit provides a certain degree of radial freedom for the adapter card in the direction of movement and also acts as a buffer and shock absorber, improving the fault tolerance and insertion / removal lifespan when the adapter card connects to the gold fingers. The side-plug assembly is detachably installed on the bottom of the push plate using hexagonal screws, allowing the installation position of the side-plug assembly to be changed according to actual testing needs, improving the applicability of the equipment. The adjusting screws can adjust the setting distance between the two sets of horizontal clamps, accommodating the installation and clamping of adapter cards of different sizes, further expanding the applicability of the equipment. Therefore, this utility model has a simple structure, can adapt to the detection of multiple sets of side-plug gold fingers, improves detection efficiency, and has a shock-absorbing function that effectively improves the equipment's lifespan and test fault tolerance.

[0016] like Figures 1 to 5As shown, this utility model includes a drive unit 1, a guide rail, a push plate 2, and several side-insertion components 3. One end of the push plate 2 is connected to the drive unit 1 and slides with the guide rail through several sliding blocks 4. Several side-insertion components 3 are detachably installed on the lower surface of the push plate 2. Each side-insertion component 3 includes a push block 31, a horizontal clamp, and an adapter 32. The horizontal clamp holds the adapter 32 and is mounted on the push block 31 through a floating unit. In this utility model, the drive unit 1 uses a cylinder as the power element, and the push plate 2 is made of black fiberglass. The sliding blocks 4 are arranged in the same direction at the four corners of its lower end face. The cylinder output shaft is connected to the push plate 2 through a connecting seat and provides stable power for its radial movement. The guide rail includes two sets of symmetrically arranged guide rails 5, with guide rail pads 6 connected to the bottom of each guide rail 5. The push plate 2 straddles the two sets of guide rails 5 and slides with the guide rails 5 through four sets of sliding blocks 4, ensuring the stability of the push plate 2 during sliding. In this utility model, the four sets of side insertion components 3 are installed at the bottom of the push plate 2 using hexagonal screws. During actual testing, the manufacturer can change the installation position of the four sets of side insertion components 3 according to the specific position of the gold fingers on the PCB board, and can also appropriately increase or decrease the number of side insertion components 3, enabling simultaneous insertion and removal tests of multiple or single gold fingers, thus improving testing efficiency.

[0017] In this invention, the floating unit includes a floating block 33, several equal-height screws 34, and a buffer spring 35. The floating block 33 is connected to the push block 31 via four equal-height screws 34 arranged in an array. A stepped hole 36 is provided in the push block 31 corresponding to the positions of the four equal-height screws 34. The buffer spring 35 is sleeved on the equal-height screws 34 and located within the stepped hole 36. During testing, the buffer spring 35 not only provides shock absorption but also offers a certain radial degree of freedom for the adapter card 32 in its direction of movement, preventing rigid impact between the adapter card 32 and the gold fingers, thus improving the test's fault tolerance.

[0018] In this invention, the horizontal clamp includes horizontal clamping blocks 37 symmetrically arranged on the left and right end faces of the floating block 33. The horizontal clamping blocks 37 are connected to the floating block 33 via adjusting screws 38, and the distance between the two horizontal clamping blocks 37 is adjustable. By rotating the adjusting screws 38, the position of the horizontal clamping blocks 37 can be adjusted, i.e., the distance between the two sets of prime horizontal clamping blocks 37 can be adjusted to accommodate the installation requirements of adapter cards 32 of different sizes. The lower inner side of each horizontal clamping block 37 is also provided with a slot 39 adapted to the adapter card 32, and a clamping boss 300 is provided in the center of the slot 39. The slot 39 and the clamping boss 300 are integrally formed with the horizontal clamping blocks 37, and are manufactured according to the requirements of adapter cards 32 of different models, sizes, and clamping positions. They can be directly replaced during use, improving the applicability of the equipment.

[0019] This invention uses a cylinder as the drive unit 1, ensuring the stability of power input and improving the efficiency of testing gold fingers. The side-insertion assembly 3 is installed in a detachable manner, allowing for free selection of the number and position of the side-insertion assembly 3, increasing the freedom of use and applicability of the equipment. The floating unit provides shock absorption and radial freedom during the insertion and removal process, preventing rigid impact between the adapter card 32 and the gold fingers, thus providing protection and improving the service life of the equipment and the fault tolerance rate during insertion.
