DETAILED DESCRIPTION

[0030] The utility model makes further explanation to the utility model below combining with the drawings and specific embodiments, so that the person skilled in the art can better understand the utility model and can be implemented, but the embodiment is not as the limitation of the utility model.

[0031] Embodiment

[0032] Refer to Figures 2-7 The utility model discloses a circuit board assembly jig, including:

[0033] The base is provided with a plurality of blind holes, and a top post is arranged in the blind hole, and the column body to be welded can be arranged on the circuit board to be welded and abutted to the top post.

[0034] The intermediate plate is provided with a plurality of limiting grooves, and the size of the limiting groove is matched with the circuit board to be welded.

[0035] The cover plate is provided with a plurality of avoiding holes, and the avoiding hole is corresponding to the position of the copper column to be welded and the antenna support, and the size of the avoiding hole is not greater than the circuit board to be welded.

[0036] The base, the intermediate plate and the cover plate are respectively provided with corresponding positioning holes, and a positioning pin is detachably arranged in the positioning hole.

[0037] The utility model discloses a circuit board assembly jig, by inserting the positioning pin into the positioning hole of the cover plate, the intermediate plate and the cover plate are combined, and the circuit board is placed in the limiting groove of the intermediate plate, and because the size of the limiting groove is matched, the circuit board is located at the predetermined position, so that the circuit board is positioned, the copper column body to be welded is inserted into the reserved hole of the circuit board to be welded, and the antenna support is assembled, at this time, the avoiding hole of the cover plate is corresponding to the position of the column body and the antenna support, the base is covered, and the blind hole on the base is corresponding to the position of the top post, so that the copper column body to be welded is supported, and the copper column and the circuit board to be welded are further positioned through the avoiding hole, the base, the intermediate plate and the cover plate are assembled and combined through the positioning pin, and the avoiding hole of the cover plate is turned up, so that a plurality of circuit boards are placed and positioned at the same time, and the circuit board can be welded through the avoiding hole, so that the welding efficiency and the positioning precision are improved.

[0038] The base is provided with at least two first protrusions, each of which is provided with a plurality of second protrusions, each group of blind holes is arranged on each second protrusion, and the bottom groove is arranged on both sides of the middle plate. The limiting hole penetrates the bottom groove. The first protrusion is accommodated in the bottom groove. When the middle plate is placed on the base, the bottom groove of the middle plate is in contact with the top of the first protrusion and the second protrusion to determine the position of the circuit board for limiting. When the copper column is placed, the blind hole on the second protrusion provides an accurate insertion position for the copper column. The height direction of the copper column is controlled by the depth of the blind hole, thereby ensuring the accurate position of the copper column in the three-dimensional space. In the welding process, the first protrusion and the second protrusion may affect the heat transfer. The heat generated by welding is conducted to the blind hole through the copper column, then to the second protrusion and the first protrusion, and finally dissipated into the air. Due to the increase of the heat dissipation path and the heat dissipation area by these protrusions, the heat can be more effectively dissipated. At the same time, due to the existence of the first protrusion and the second protrusion, the relative position of the circuit board and the copper column is more stable during welding. The force exerted by the welding tool on the copper column will not cause displacement of the copper column or the circuit board, thereby ensuring the stability and quality of welding.

[0039] Referring to Figure 3 As shown in the drawings, the copper column at least includes a first copper column, a second copper column and a third copper column. The first copper column and the third copper column are arranged on one side of the circuit board to be welded. The avoiding hole includes a first sub-hole and a second sub-hole. The first sub-hole is used to avoid the first copper column, the second copper column and the antenna support to be welded. The second sub-hole is used to avoid the third copper column to be welded. The second copper column is arranged on the other side of the circuit board to be welded. Due to the distribution of the copper columns on both sides, the circuit board can be more stably placed on the middle plate in the horizontal direction, thereby avoiding the inclination or deviation of the circuit board caused by uneven distribution of the copper columns.

[0040] The first base, the middle plate and the cover plate are respectively provided with corresponding first positioning holes, second positioning holes and third positioning holes. The center lines of the first positioning hole, the second positioning hole and the third positioning hole are collinear. In assembly, the collinear design of the center lines of the positioning holes enables the positioning pin to pass through the first positioning hole, the second positioning hole and the third positioning hole in the vertical direction in turn, thereby accurately positioning the base, the middle plate and the cover plate in the vertical direction. In the horizontal direction, due to the collinear center lines, the relative positional relationship of the components is fixed and cannot deviate in the horizontal direction.

[0041] The inner diameter of the second positioning hole and the third positioning hole is larger than the inner diameter of the first positioning hole, bushings are respectively embedded in the second positioning hole and the third positioning hole, a positioning pin is fixedly connected to the first positioning hole, the inner diameter of the bushing is equal to the inner diameter of the first positioning hole, one end of the positioning pin penetrates the bushing, the bushing ensures positioning accuracy while reducing direct wear between the positioning pin and the inner wall of the positioning hole, thereby prolonging the service life of the jig and maintaining high positioning accuracy after multiple uses.

[0042] Referring to Figures 3-6 As shown in the drawings, the base, the middle plate and the cover plate are respectively provided with corresponding locking holes, the locking holes are threaded holes, bolts are threadedly matched in the locking holes, and the base, the middle plate and the cover plate are locked by the bolts to maintain the flatness of the jig.

[0043] Referring to Figure 4 As shown in the drawings, the head of the bolt is embedded in the base, and the head of the limiting pin is embedded in the cover plate, when the locking of the bolt is required, the bolt and the limiting pin are locked from the two sides of the jig to increase the locking force, and the additional locking is performed after the jig is turned over, i.e. when the cover plate is upward, which can optimize the beat of the jig assembly.

[0044] The embodiment also discloses an assembly mechanism comprising the circuit board assembly jig.

[0045] The assembly mechanism disclosed by the embodiment combines the circuit board and the component to be welded to form a to-be-welded state by using the circuit board assembly jig, and the welding mechanism is used to weld the column through the avoiding hole, so that the circuit board and the antenna support are welded, the welding mechanism adopts a laser welding machine or a soldering iron welding mechanism, and is arranged at the output end of the three-axis moving mechanism, the three-axis moving mechanism is controlled by the control unit, and the welding mechanism is used to weld the copper column at each position.
