Example:

Figure 1 is a first view of an assembly tool for PCB components provided by an embodiment of the present invention. Figure 2 is a second view of an assembly tool for PCB components provided by an embodiment of the present invention. Combined with Figure 1 and As shown in Figure 2, the assembly tooling includes a base 1 and a positioning component 2.

One side of the base 1 has a relief groove 11 and a plurality of legs 12 . The plurality of legs 12 are arranged on the base 1 at intervals to support the base 1 .

The positioning assembly 2 includes a clamping piece 21 and a pressing piece 22. The clamping piece 21 is located on the base 1. The clamping piece 21 is used to clamp the first board body 100 of the PCB assembly above the relief groove 11 in the first direction. , the pressing member 22 is movably arranged on the base 1 to press the power board 200 of the PCB assembly above the relief groove 11 along the second direction.

Regarding an assembly tool for PCB components according to the embodiment of the present invention, when assembling the PCB component, first, place the first board body 100 of the PCB component on the base 1. At this time, the first board body 100 faces the base 1. The components are located in the escape groove 11, and the first board body 100 is clamped by the clamping member 21, so that the first board of the PCB assembly is clamped in the horizontal direction (direction parallel to the base 1) through the clamping member 21. The body 100 is clamped above the escape groove 11 to prevent it from moving in the horizontal direction. Then, a plurality of conductive pins 300 are inserted on the first board body 100, and a power board 200 is inserted on top of the plurality of conductive pins 300. The power board 200 and the first board body 100 are arranged in parallel and spaced apart, so that through the conductive pins 300 Positioning of the power board 200 is achieved. At this time, the first board body 100 is on the bottom, the power board 200 is on the top, and the legs 12 are arranged upward. Next, the pressing member 22 is moved so that the pressing member 22 presses the power board 200 onto the conductive pins 300 . The conductive pins 300 are sandwiched between the power board 200 and the first board body 100 , and each conductive pin 300 is The insertion depth in the power board 200 is consistent, so that the overall positioning of the PCB board, the conductive pins 300 and the power board 200 can be easily realized in the vertical direction through the pressing member 22 (see Figures 3 and 4), thereby ultimately ensuring that the first The relative positions of the plate body 100 and the power board 200 in space prevent relative movement between each other during the subsequent welding process. In addition, under the action of the pressing member 22, the pressing force between the power board 200 and the first plate body 100 is constant and is not affected by flipping. On this basis, multiple conductive pins 300 and the power board 200 are welded, so that the conductive pins 300 and the power board 200 are welded under the positioning and pressing force of the clamping member 21 and the pressing member 22 . Finally, the base 1 is turned over so that the relief groove 11 and the plurality of legs 12 are arranged downward (see Figure 5). At this time, the first board body 100 is on top, the power board 200 is on the bottom, and the legs 12 are facing downward to support the base 1. The power board 200 is raised by the legs 12 without being squeezed or touched by the outside world. And the first board body 100 and the plurality of conductive pins 300 are welded, thereby finally assembling the PCB assembly.

That is to say, the assembly tool for PCB components provided by the embodiment of the present invention can conveniently realize the overall positioning of the PCB board, the conductive pins 300 and the power board 200 through the clamping part 21 and the pressing part 22, ensuring the first The relative position of the board body 100 and the power board 200 ensures that the pressing force between the power board 200 and the first board body 100 is constant, thereby improving the assembly efficiency of PCB components and ensuring the consistency of assembly quality in mass production.

It should be noted that in this application, conductive pins 300 are used to weld the power board 200 and the first board body 100. The conductive pins 300 occupy less space and are conducive to the requirement of high-density light transmission.

For example, the number of conductive pins 300 can be 4-6, and both ends of the conductive pins 300 have an inverted T-shaped structure or a limiting structure, and can be inserted into the power board 200 and the first board body respectively. In the through hole on 100, the power board 200 and the first board body 100 can also be limited, thereby preventing the first board body 100 from contacting the power board 200.

It is easy to understand that the escape groove 11 can make the components on the back of the first board 100 suspended, which not only allows the first board 100 to be arranged parallel to the base 1, but also prevents the components from being worn by the base 1 (see Figure 3) .

In this embodiment, the plurality of legs 12 and the base 1 form a space for accommodating the PCB assembly and the pressing member 22, so that the PCB assembly and the pressing member 22 are located in the space, thereby saving the space occupied by the entire assembly tool.

In one implementation of the present invention, Figure 6 is a partial structural schematic diagram of a clamping member provided by an embodiment of the present invention, and Figure 7 is a schematic structural diagram of a base provided by an embodiment of the present invention. As shown in combination with Figures 6 and 7, The clamping member 21 includes a limiting plate 211, a sliding block 212 and a screw rod 213. The limiting plate 211 and the sliding block 212 are respectively located on both sides of the escape groove 11. The sliding block 212 is slidable in the direction toward the limiting plate 211. Arranged on the base 1, the limiting plate 211 is located on the base 1, and the screw rod 213 is rotatably inserted into the base 1. One end of the screw rod 213 is threadedly matched with the slider 212.

In the above embodiment, the slider 212 can be driven to slide by rotating the screw rod 213, so that the slider 212 moves toward the limiting plate 211, thereby cooperating with the limiting plate 211 to clamp the first plate body 100 in the horizontal direction.

Exemplarily, the base 1 has a guide groove 14 extending along the direction in which the slider 212 slides. A slider 141 is slidably inserted into the guide groove 14 (see Figure 8). The slider 141 and the slider 212 are fixedly connected. , and the end of the screw rod 213 is threadedly matched with the sliding seat 141. In addition, a cover plate 15 is inserted above the guide groove 14, and the cover plate 15 plays a role in limiting the position of the sliding seat 141 to prevent the base 1 from being detached from the guide groove 14 after being turned over.

That is to say, the rotation of the screw rod 213 can be converted into a linear movement of the slide base 141 along the guide groove 14, thereby driving the slide block 212 to slide, and then cooperate with the limiting plate 211 to clamp the first plate body 100.

For example, the number of slide blocks 212 on the slide base 141 can be two, and the two slide blocks 212 are arranged at intervals, thereby improving the clamping effect.

In addition, there are a plurality of positioning posts arranged at intervals on the limiting plate 211, and the side of the first plate body 100 has positioning grooves. The positioning of the first plate body 100 is achieved through the cooperation of the positioning posts and the positioning grooves.

Furthermore, the two opposite sides of the limiting plate 211 and the slider 212 are inclined surfaces, and one end of the two inclined surfaces facing away from the relief groove 11 is located above the first board body 100 of the PCB assembly. The two inclined surfaces can not only cooperate to clamp the first plate body 100, but also form a limit above the first plate body 100 to prevent the first plate body 100 from moving upward and escaping from the escape groove 11 during the clamping process.

For example, the limiting plate 211 can be integrally formed with the base 1 (that is, the limiting plate 211 can be regarded as a step on the base 1).

In another implementation of the present invention, the clamping member 21 includes at least two clamping units (not shown). The two clamping units are respectively located on both sides of the escape groove 11. Each clamping unit includes a fixed Block and screw rod, the fixed block is located on the base, each screw rod is threaded with the corresponding fixed block, and the screw rod penetrates the fixed block.

In the above embodiment, the fixed block plays a role in supporting the screw rods, and the first plate body 100 is finally clamped through the movement of multiple screw rods.

In one embodiment of the present invention, the pressing member 22 includes a pressing head 221 and a rotating frame 222. One end of the rotating frame 222 is rotatably inserted into the base 1, and the pressing head 221 is located on the other end of the rotating frame 222. To compress the power board 200 of the PCB assembly.

It is easy to understand that the turret 222 can drive the pressure head 221 to rotate, thereby rotating the pressure head 221 to directly above the power board 200 to compress the power board 200 . In addition, even after being turned over, the pressure head 221 can still limit the position of the power supply board 200 under the support of the turret 222 . During the process of moving the first plate body 100 up and down, the turret 222 can rotate 100-120°, thereby driving the pressure head 221 away from the escape groove 11, thereby facilitating loading and unloading of materials.

Illustratively, the turret 222 is an L-shaped structure.

Further, the pressing member 22 also includes an elastic module. The elastic module includes a cylinder 223, a spring 224 and a connecting bolt 225. The cylinder 223 is fixedly connected to the turret 222. The inner peripheral wall of the cylinder 223 has an inner flange 2231. The connecting bolt 225 is inserted into the cylinder 223, and the bottom end of the connecting bolt 225 is connected to the base 1, the nut of the connecting bolt 225 is located above the inner flange 2231, and the spring 224 is sandwiched between the nut of the connecting bolt 225 and the inner flange 2231. between (see Figure 9).

In the above embodiment, the spring 224 has an elastic force toward the inner flange 2231 and the cylinder 223 toward the base 1 , so that the pressure head 221 firmly presses the power board 200 . When it is necessary to rotate the turret 222 to compress the power board 200, the cylinder 223 is lifted up against the elastic force of the spring 224, and the cylinder 223 will drive the turret 222 and the pressure head 221 to move upward. At this time, the connecting bolt 225 can be used as the The shaft turns the turret 222. When the pressure head 221 rotates to just above the power board 200, the cylinder 223 is slowly released, and the spring 224 drives the cylinder 223 to move downward, thereby driving the pressure head 221 to press the power board 200. Through the setting of the spring 224, the compression can be ensured and the installation error of the pressure head 221 can be compensated.

Illustratively, the base 1 has a mounting base 226, and the connecting bolts 225 are mounted on the mounting base 226.

In addition, the pressure head 221 is provided with an elastic pad, and the elastic pad is arranged toward the relief groove 11 to prevent the pressure head 221 from pressing against the components on the power supply board 200 .

For example, the elastic pad uses soft materials, such as silicone, foam, etc. The elastic pad has a groove in the middle, which can avoid the silicon-based components on the power board 200 , while the elastic pad only contacts the electrical components on the power board 200 .

In another embodiment of the present invention, the pressing member 22 includes a pressure head 221 and a sliding frame (not shown). One end of the sliding frame is slidably arranged on the base 1, and the sliding direction of the sliding frame is perpendicular to the avoidance. slot 11, the pressure head 221 is located on the other end of the sliding frame to press the power board 200 of the PCB assembly, thereby adjusting the position of the pressure head 221 by sliding the sliding frame, so that the pressure head 221 slides to directly above the power board 200 , so that the power board 200 can also be pressed.

In this embodiment, the base 1 has positioning grooves 13 , which are spaced apart from the relief grooves 11 . The positioning grooves 13 are used to accommodate the second board body 400 of the PCB assembly.

In the above embodiment, the positioning groove 13 can realize the positioning of the second board body 400 of the PCB assembly.

Further, the second plate body 400 can be bonded in the positioning groove 13 through adhesive, thereby preventing the second plate body 400 from swinging during the flipping process.

It should be noted that the first board body 100 and the second board body 400 are electrically connected through a second flexible circuit board (FPC). Through the arrangement of multiple boards, the layout area of the PCB assembly is increased and the transmission rate is improved.

For example, the second flexible board is inserted between the two sliders 212 to avoid the second flexible board.

Referring again to FIG. 1 , the base 1 has an escape groove 16 , which is provided through one side of the base 1 along the second direction (vertical direction) to form a welding avoidance space for PCB components.

It is easy to understand that the relief groove 16 is arranged opposite to the first plate body 100 , so as to avoid interference with the welding between the conductive pin 300 and the first plate body 100 .
