[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention employs a positioning mechanism: after the HDI board is placed in the tray, rotating the first rotating shaft drives the first lead screw to rotate. At this time, the sliding bracket on the surface of the first lead screw moves due to the limiting bracket and other structures, thereby adjusting the lateral position of the HDI board. After the lateral adjustment is completed, rotating the second rotating shaft drives the second lead screw to rotate, thereby moving the slider to adjust the longitudinal position of the HDI board. When the first or second lead screw needs replacement or maintenance due to prolonged use or other damage, rotating the first rotating shaft or the second lead screw... The rotating ring releases the limiting effect on the first and second clamping plates, and simultaneously releases the limiting effect on the first lead screw and the second rotating ring. This allows the first or second lead screw to be easily pulled out for replacement or maintenance. The design of using the rotation of the first and second lead screws to adjust the position of the HDI board and the rotation of the first and second rotating rings to release the limiting effect on the first and second lead screws achieves the purpose of conveniently adjusting the position of the HDI board while quickly disassembling and assembling the first or second lead screw, making subsequent maintenance of the device more convenient and improving the practicality of the device.

The design of pressing down the rotating bracket and rotating it around a bearing as the center point achieves the goal of easy removal of the HDI board after processing, thus improving its practicality.

[0029] The positioning mechanism 1 includes a first rotating shaft 101. A first threaded bracket 102 is fixedly connected to the right end of the first rotating shaft 101. A first clamping plate 103 is rotatably connected to the inner wall of the first threaded bracket 102. A first rotating ring 104 is threadedly connected to the surface of the first threaded bracket 102. A first lead screw 105 is clamped to the inner wall of the first clamping plate 103. A sliding bracket 106 is threadedly connected to the surface of the first lead screw 105. A second rotating shaft 107 is rotatably connected to the inner wall of the sliding bracket 106. A second threaded bracket 108 is fixedly connected to the bottom end of the second rotating shaft 107. A second threaded bracket 108 is rotatably connected to the inner wall of the second threaded bracket 108. The second screw rod 111 is threadedly connected to the surface of the clamping plate 109 and the second screw bracket 108. The inner wall of the second clamping plate 109 is clamped with the second screw rod 111. The design of adjusting the position of the HDI plate by rotating the first screw rod 105 and the second screw rod 111 and releasing the limiting position of the first screw rod 105 and the second screw rod 111 by rotating the first screw rod 104 and the second screw rod 110 achieves the purpose of conveniently adjusting the position of the HDI plate and quickly disassembling and assembling the first screw rod 105 or the second screw rod 111, making subsequent maintenance of the device more convenient and improving the practicality of the device.

[0030] The inner wall of the first rotating ring 104 is threadedly connected to the surface of the first clamping plate 103, the inner wall of the second rotating ring 110 is threadedly connected to the surface of the second clamping plate 109, and the surface of the second lead screw 111 is rotatably connected to the inner wall of the sliding frame 106.

[0031] The support mechanism 2 includes a tray 201, a slider 202 is fixedly connected to the lower end of the tray 201, a bearing 203 is rotatably connected to the inner wall of the tray 201, and a rotating frame 204 is fixedly connected to the surface of the bearing 203. By pressing the rotating frame 204 to make it rotate around the bearing 203 as the center point, the HDI board can be easily removed after processing, thus improving its practicality.

[0032] The two sides of the rotating frame 204 are rotatably connected to the inner wall of the tray 201, and the inner wall of the slider 202 is threadedly connected to the surface of the second lead screw 111.

[0033] The protective mechanism 3 includes a protective housing 301, a mounting bracket 302 fixedly connected to the surface of the protective housing 301, and a limit bracket 303 fixedly connected to the inner wall of the protective housing 301.

[0034] The inner wall of the protective housing 301 is rotatably connected to the surface of the first rotating shaft 101, and the inner wall of the protective housing 301 is slidably connected to the surface of the sliding frame 106.

[0036] The implementation principle of a positioning device for improving the hole alignment accuracy of an HDI board in this embodiment is as follows: When using this device, the HDI board is first placed in the tray 201 to facilitate subsequent adjustment of its position. The rotating frame 204 on the side of the tray 201 is used to press down the HDI board after processing to lift it up for easy removal. The design of pressing down the rotating frame 204 to rotate around the bearing 203 as the midpoint achieves the purpose of easy removal of the HDI board after processing, improving practicality. After the HDI board is placed in the tray 201, the first rotating shaft 101 is rotated to drive the first lead screw 105 to rotate. At this time, the sliding frame 106 on the surface of the first lead screw 105 moves on the surface of the first lead screw 105 due to the limiting frame 303 and other structures, thereby adjusting the lateral position of the HDI board. After the lateral adjustment is completed, the second rotating shaft 107 is rotated to drive the second lead screw 111 to rotate, thereby driving the slider 2 02. The HDI board can be moved to adjust its longitudinal position. When the first lead screw 105 or the second lead screw 111 is damaged due to prolonged use or other reasons and needs to be replaced or maintained, the first rotating ring 104 or the second rotating ring 110 can be rotated to release the restriction on the first clamping plate 103 and the second clamping plate 109. At the same time, the first clamping plate 103 and the second clamping plate 109 can release the restriction on the first lead screw 105 and the second rotating ring 110, so that the first lead screw 105 or the second lead screw 111 can be easily pulled out to complete the replacement or maintenance. The design of using the rotation of the first lead screw 105 and the second lead screw 111 to adjust the position of the HDI board and the rotation of the first rotating ring 104 and the second rotating ring 110 to release the restriction on the first lead screw 105 and the second lead screw 111 achieves the purpose of conveniently adjusting the position of the HDI board and quickly disassembling and assembling the first lead screw 105 or the second lead screw 111, making subsequent maintenance of the device more convenient and improving the practicality of the device.
