DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A PCBA assembly tool comprises a base 1, a hidden groove 2 and a movable groove 4 are provided on the upper end surface of the base 1, a transmission chamber 10 and a device chamber 11 are provided inside the base 1, a driving gear 13 is rotatably provided on the bottom wall of the transmission chamber 10, a power mechanism connected to the driving gear 13 is provided in the device chamber 11, an adjusting screw 14 is provided in the movable groove 4, the adjusting screw 14 is connected to the driving gear 13 through a rotating mechanism, a top plate 3 is provided in the hidden groove 2, the top plate 3 is connected to the driving gear 13 through a connecting mechanism, a positioning plate 5 is threadedly sleeved on the adjusting screw 14, a rotating port 7 is provided on the positioning plate 5, a lifting screw 18 is provided in the rotating port 7, a limit plate 6 is threadedly sleeved on the lifting screw 18, a rack 9 is provided on the upper end surface of the base 1, and the lifting screw 18 is connected to the rack 9 through a transmission mechanism.

[0023] The power mechanism includes a drive motor 12 arranged in the equipment cavity 11. The output shaft of the drive motor 12 is connected to the driving gear 13. The drive motor 12 is a power device. The bottom wall of the base 1 is also provided with a plurality of heat dissipation ports connected to the equipment cavity 11 to facilitate heat dissipation operation after the drive motor 12 is working.

[0024] The rotating mechanism includes a transmission gear 15 installed on the adjusting screw 14, and the driving gear 13 is meshed with the transmission gear 15. As shown in the figure, the driving gear 13 and the transmission gear 15 are both bevel gears, and the two are in a vertical meshing relationship.

[0025] The connecting mechanism includes a threaded sleeve 17 installed on the top plate 3, and a top-feeding screw 16 is installed on the driving gear 13. The threaded sleeve 17 is threadedly sleeved and installed on the top-feeding screw 16. The threaded sleeve 17 is a rectangular body, which slides through the bottom wall of the hidden groove 2, so it has its own limit and will not rotate with the top-feeding screw 16.

[0026] The transmission mechanism includes a threaded sleeve 17 installed on the positioning plate 5, and a top material screw 16 is installed on the driving gear 13. The threaded sleeve 17 is threadedly installed on the top material screw 16. As the driving gear 13 and the top material screw 16 rotate synchronously, the threaded sleeve 17 can drive the top plate 3 to rise and fall in the hidden groove 2.

[0027] A horizontal bar is arranged in the movable groove 4, the horizontal bar is parallel to the adjustment screw 14, and the horizontal bar slides through the positioning plate 5. A vertical bar is arranged in the rotating opening 7, the vertical bar is parallel to the lifting screw 18, and the vertical bar slides through the limit plate 6. The horizontal bar and the vertical bar both play a role of limiting, realizing the limiting of the positioning plate 5 and the limit plate 6, thereby preventing them from rotating together with the adjustment screw 14 and the lifting screw 18.

[0028] When the utility model is used, the top plate 3 is exposed, and the distance between the four positioning plates 5 is the largest. Then, the PCB board is placed on the top plate 3 and is between the four positioning plates 5, and then the driving motor 12 is started. The driving motor 12 drives the active gear 13 and the ejecting screw 16 to rotate, and the top plate 3 is lowered into the hidden groove 2 and hidden. The PCB board is placed on the upper end surface of the base 1. At the same time, the active gear 13 and the transmission gear 15 can drive the adjusting screw 14 to rotate. When the adjusting screw 14 rotates, the positioning plate 5 moves close to realize the positioning and clamping operation of the four outer walls of the PCB board. In this process, the lifting screw 18 rotates under the action of the rotating gear 8 and the rack 9, which drives the limit plate 6 to descend, and realizes the downward pressing and positioning operation of the upper end surface of the PCB board. While ensuring its stability, it is convenient to assemble and process it.

[0029] After the assembly process is completed, the driving motor 12 is reversed to release the positioning clamping of the positioning plate 5 and the limiting plate 6 synchronously, and the top plate 3 pushes the PCB board out again for easy removal.

[0030] It should be noted that in this solution, the dimensions of multiple components are precise and will not interfere with each other.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
