Description

Technical Field

[0001] This utility model relates to the field of electronic processing, and in particular to an assembly device for irregularly shaped Minifit pins. Background Technology

[0002] Mini-fit is a blind-mating connector.

[0003] See Figure 1 This is an irregularly shaped mini-fit. The base of this mini-fit has a flat bottom and a sloping top. Slots are provided on both the bottom and top surfaces, with the bottom of these slots perpendicular to the height of the base. These slots are connected by multiple mounting holes extending along the height direction, arranged in a 2x3 matrix and evenly spaced along the length of the mini-fit base. The two side walls of the mini-fit base are equipped with latches and buckles, extending above the high and low ends of the sloping base, respectively.

[0004] After the Mini-fit base is formed, socket-type terminals need to be installed in the mounting holes of the bottom slot, flush with the bottom of the slot. Pin-type terminals need to be installed in the mounting holes of the top slot, and the pins are required to be at the same height above the slope and be distributed perpendicular to the slope.

[0005] After the pre-assembly process pre-assembles the pins into the sockets in the slots at the top of the base, since the pins are of the same specification and the absolute height of each row of pins is consistent, these pins need to be manually pressed in so that the insertion depth of the three rows of pins is different and the height above the slope is consistent. The protruding end of each pin is also bent at an angle to ensure that the protruding height of each row of pins is consistent. This results in low assembly efficiency and makes it impossible to guarantee the stability of quality.

[0006] Therefore, designing a low-cost tooling that can assist manual assembly of these irregularly shaped mini-fit pins quickly and stably is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing an assembly device for irregularly shaped mini-fit pins. This device has a simple structure, low manufacturing cost, and can efficiently and stably assemble mini-fit pins, reducing manual labor intensity, ensuring product quality, and enhancing market competitiveness.

[0008] The technical solution to achieve the purpose of this utility model is: an assembly device for irregularly shaped mini-fit pins, including a base plate and a pressing fixture fixed on the base plate. The pressing fixture includes a base, a loading platform, and a pressing head. An L-shaped positioning frame is provided on the base. The loading platform has a cuboid structure. The top surface of the cuboid loading platform has a loading groove that runs through the length direction. The width of the loading groove is adapted to the length of the irregularly shaped mini-fit, and the depth is less than the height of the irregularly shaped mini-fit. The pressing head is driven to move up and down by a telescopic cylinder and is located above the L-shaped positioning frame. The pressing surface of the pressing head has a three-step surface, which corresponds to the three rows of pins pre-installed on the mini-fit base.

[0009] The pressure head is composed of a first pressure block, a second pressure block, and a third pressure block stacked together. The bottom surfaces of the first pressure block, the second pressure block, and the third pressure block are at different heights, forming a stepped surface.

[0010] It also includes a mounting base with an L-shaped cross-section. The first pressure block, the second pressure block, and the third pressure block overlap and are fixed in the mounting base with bolts. The mounting base is connected to the piston rod of the telescopic cylinder.

[0011] The L-shaped positioning frame is composed of a first positioning block and a second positioning block that are vertically distributed and spliced ​​together.

[0012] A frame consisting of a top plate, a vertical plate, and a bottom plate is fixedly mounted on the base plate, with the bottom plate forming a base and the telescopic cylinder mounted on the top plate.

[0013] The first side of the L-shaped positioning frame is perpendicular to the vertical plate and extends away from the vertical plate.

[0014] The above technical solution has the following beneficial effects:

[0015] 1. The assembly device for irregularly shaped mini-fit pins includes a base plate and a pressing fixture fixed on the base plate. The pressing fixture is used to press the pre-assembled pins to a specified position, ensuring that the length of each pin extending out of the top surface of the mini-fit base is the same. The pressing fixture includes a base, a loading platform, and a pressing head. The base is provided with an L-shaped positioning frame. The loading platform has a cuboid structure, and the top surface of the cuboid loading platform is provided with a loading groove that runs through the length direction. The width of the loading groove is adapted to the length of the irregularly shaped mini-fit, and the depth is less than the height of the irregularly shaped mini-fit. That is, multiple pre-assembled mini-fit primary products with pins can be loaded on the loading platform, and the loading platform cooperates with the L-shaped positioning frame to achieve the purpose of quickly positioning multiple mini-fit primary products. The press head is driven to move up and down by a telescopic cylinder and is located above the L-shaped positioning frame. The pressing surface of the press head is a three-step surface, which corresponds to the three rows of pins pre-installed on the mini-fit base. Multiple mini-fit primary products can be pressed into place at one time to obtain intermediate products. The overall efficiency is high and the pressing quality is guaranteed to be stable.

[0016] 2. The pressure head is composed of three overlapping pressure blocks: a first pressure block, a second pressure block, and a third pressure block. The bottom surfaces of these blocks are at different heights, forming a stepped surface. This effectively reduces the processing cost of the pressure head, and the thickness and bottom height of each block can be adjusted according to actual needs to meet the specific requirements of the enterprise. 3. The L-shaped positioning frame is constructed from vertically distributed first and second positioning blocks. Its simple structure and easy adjustment meet the actual needs of the enterprise.

[0027] 1) Take the mini-fit primary products obtained from multiple pre-assembly processes (that is, the absolute height of the three rows of pins is the same), and load them side by side into the loading slot of the loading platform, so that each row of pins faces upward;

[0028] 2) The mobile loading platform works in conjunction with the L-shaped positioning frame to position the loading platform.

[0029] 3) Manually control the pressure head to press down until it reaches the correct position, ensuring that the three rows of pins are at the same height above the inclined plane, thus obtaining a mini-fit intermediate product for downstream bending process.
