Description

Technical Field

[0001] This utility model belongs to the field of programming machine technology, specifically relating to a multi-station programming machine for PCBA boards. Background Technology

[0002] In modern electronics manufacturing, PCBA board programming is an essential part of the production process. PCBA board programming usually involves writing program data or configuration information into the memory chips on the board. The traditional programming process often requires manual placement of PCBA boards one by one into the programming equipment, which is too inefficient. Therefore, multi-station programming machines have emerged.

[0003] However, PCBA boards inevitably need to be positioned during programming. Without positioning, it cannot be ensured that the pins on the programming board are properly connected. Multi-station programming machines need to position multiple PCBA boards one by one, resulting in very low efficiency. Therefore, we propose a multi-station PCBA board programming machine. Utility Model Content

[0004] The purpose of this invention is to provide a PCBA board multi-station programming machine that can quickly locate the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A PCBA board multi-station programming machine includes a programming machine body and a programming board disposed on the programming machine body, wherein a tray is movably disposed on the programming machine body;

[0007] It also includes:

[0008] An extrusion block is disposed on the main body of the burner;

[0009] An expansion mechanism is installed in the tray. The tray is squeezed by the extrusion block, causing the expansion mechanism to expand to both sides.

[0010] A fixing strip is slidably mounted on the tray, and the fixing strip is pushed to both sides by an expanded mechanism.

[0011] As a further optimization of this utility model, the tray is provided with multiple placement slots, which are arranged symmetrically on the tray. Positioning ears are provided on both sides of the tray, and a receiving cavity is provided inside the tray.

[0012] As a further optimization of this utility model, the expansion mechanism includes a pressure column, which is slidably disposed in the receiving cavity. One end of the pressure column penetrates the side wall of the tray. A return spring is provided between the pressure column and the receiving cavity. An expansion bar is slidably disposed in the receiving cavity. The expansion bar is disposed on both sides of the pressure column. A connecting rod is rotatably disposed between the expansion bar and the pressure column. An inclined surface is provided at the end of the pressure column away from the return spring.

[0013] As a further optimization of this utility model, a sliding rod is provided on the fixing strip. The sliding rod passes through the side wall of the placement groove and extends into the receiving cavity. The fixing strip is connected to the expansion strip through the sliding rod, and the expansion strip is slidably disposed in the receiving cavity through the sliding rod.

[0014] As a further optimization of this utility model, the extrusion block has an inclined surface on one side that matches the inclined surface of the pressure column, and the extrusion block and the pressure column can be extruded.

[0015] As a further optimization of this utility model, the main body of the burner is provided with limiting posts, which are located on both sides of the tray and can be embedded in the positioning ears.

[0016] The beneficial effects of this utility model are as follows:

[0017] Unlike existing technologies, this technology enables rapid positioning and fixing of multiple PCBA boards through the cooperation of the tray and expansion mechanism in actual use. When the tray is placed on the main body of the burner and the limiting post is embedded in the positioning ear, the tray is accurately positioned. Then, the extrusion block extrudes the pressure post, causing the expansion mechanism to expand to both sides and push the fixing strip to clamp and fix the PCBA board. This avoids the need to position multiple PCBA boards one by one, greatly improving the production capacity and efficiency of the equipment. Attached Figure Description

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] like Figure 1 - Figure 5 As shown, a PCBA board multi-station programming machine includes a programming machine body 1 and a programming board 2 disposed on the programming machine body 1, and a tray 3 is movably disposed on the programming machine body 1;

[0026] It also includes:

[0027] Extrusion block 4 is disposed on the main body 1 of the burner;

[0028] The expansion mechanism 6 is installed in the tray 3. The tray 3 is squeezed by the extrusion block 4, causing the expansion mechanism 6 to expand to both sides.

[0029] The fixing strip 7 is slidably mounted on the tray 3, and the fixing strip 7 is pushed to both sides by the expanded mechanism 6.

[0030] The tray 3 has multiple placement slots 31 arranged symmetrically on the tray 3. Positioning ears 32 are provided on both sides of the tray 3. The tray 3 has a receiving cavity 33. By arranging the placement slots 31 symmetrically on the tray 3, when the expansion mechanism 6 drives the fixing strip 7 to expand, the PCBA boards on both sides can be fixed.

[0031] The expansion mechanism 6 includes a pressure column 61, which is slidably disposed in the receiving cavity 33. One end of the pressure column 61 penetrates the side wall of the tray 3. A return spring 64 is disposed between the pressure column 61 and the receiving cavity 33. An expansion bar 63 is slidably disposed in the receiving cavity 33. The expansion bar 63 is disposed on both sides of the pressure column 61. A connecting rod 62 is rotatably disposed between the expansion bar 63 and the pressure column 61. An inclined surface is opened at the end of the pressure column 61 away from the return spring 64. When the pressure column 61 slides into the receiving cavity 33 and compresses the return spring 64, the connecting rod 62 pushes the expansion bar 63 to expand to both sides in the receiving cavity 33.

[0032] A sliding rod 71 is provided on the fixing strip 7. The sliding rod 71 passes through the side wall of the placement groove 31 and extends into the receiving cavity 33. The fixing strip 7 is connected to the expansion strip 63 through the sliding rod 71. The expansion strip 63 is slidably disposed in the receiving cavity 33 through the sliding rod 71. The sliding rod 71 restricts the movement direction of the expansion strip 63.

[0033] The extrusion block 4 has an inclined surface on one side that matches the inclined surface of the pressure column 61. The extrusion block 4 and the pressure column 61 can be extruded. When the extrusion block 4 and the pressure column 61 come into contact, their inclined surfaces press against each other. Due to the extrusion force of the extrusion block 4, the pressure column 61 begins to slide into the receiving cavity 33.

[0034] The main body 1 of the burner is provided with limiting posts 5, which are located on both sides of the tray 3. The limiting posts 5 can be embedded in the positioning ears 32. The limiting posts 5 can be used to fix the tray 3 in a precise position on the main body 1 of the burner, laying the foundation for subsequent burning operations.

[0035] It should be noted that, in this multi-station PCBA board programmer, the PCBA board is first placed in the placement slot 31 on the tray 3, and then the tray 3 is placed on the programmer body 1. At this time, the limiting post 5 on the programmer body 1 is embedded into the positioning ears 32 on both sides of the tray 3 to achieve precise positioning of the tray 3. The tray 3 has a receiving cavity 33 inside, and there is an expansion mechanism 6 in the receiving cavity 33. One end of the pressure post 61 of the expansion mechanism 6 penetrates through the side wall of the tray 3 and has an inclined surface. A return spring 64 is provided between the expansion mechanism 6 and the receiving cavity 33. There are expansion bars 63 on both sides that are rotatably connected to the expansion bar 63 through the connecting rod 62. When the inclined surface of the extrusion block 4 on the programmer body 1 is aligned with the expansion mechanism 6, the expansion mechanism 6 can be adjusted to ensure proper positioning of the tray 3. When the pressure column 61 is squeezed, it slides into the receiving cavity 33 and compresses the return spring 64. With the help of the connecting rod 62, it pushes the expansion bar 63 to expand to both sides in the receiving cavity 33. The fixing bar 7, which is set on the tray 3 and connected to the expansion bar 63 through the sliding rod 71, passes through the side wall of the placement groove 31 and extends into the receiving cavity 33. Under the expansion action of the expansion bar 63, the fixing bar 7 is pushed to both sides through the sliding rod 71, thereby clamping and fixing the PCBA board placed in the placement groove 31. In this way, the positioning of all PCBA boards can be completed during the placement of the tray 3. Finally, the burning board 2 on the main body of the burner 1 can perform the burning operation on the PCBA board.

[0036] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
