Description

Technical Field

[0001] The utility model relates to the technical field of PCB board welding processing, in particular to a PCB board welding tool. Background Art

[0002] PCB board welding refers to the process of welding components to a printed circuit board (PCB) to achieve electrical connection and mechanical fixation. This process requires heating the welding point to combine it with the copper foil on the circuit board. PCB welding is one of the indispensable processes in manufacturing electronic equipment and electronic products. The welding process of PCB boards needs to be performed on a special welding tool. However, traditional welding tools generally place the PCB board flat on it and then clamp it, and then perform welding. However, to weld components on a PCB board, it is often necessary to insert the solder feet of the components into the solder holes of the PCB board, and then perform welding operations on the other side. This requires the PCB board to be repeatedly turned over on the tooling, affecting the welding efficiency of the components.

[0025] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0026] A PCB board welding tool, comprising an operation box 1, a mounting frame 2 is installed on the shorter side surface of the operation box 1, a forward and reverse motor 3 is installed on the inner side surface of the mounting frame 2, a transmission wheel 4 is symmetrically installed at both ends of a side surface of the operation box 1 on which the mounting frame 2 is installed, a belt 5 is installed on the transmission wheel 4, a hand wheel 6 is installed at the center of a longer side surface of the operation box 1, an L-shaped frame 7 is symmetrically installed at one end of the two longer side surfaces of the operation box 1, a screw rod 8 is installed at one end of the L-shaped frame 7, and a pressure block 9 is installed at one end of the screw rod 8;

[0027] A groove 101 is provided on the top of the operating box 1, and a baffle 10 is installed at the top position of the inner side surface of the groove 101. A screw 11 is connected between the two ends of the two shorter inner sides of the groove 101, and two clamping rings 12 are symmetrically installed on the screw 11. A rotating shaft 13 is installed at the center of the bottom of the inner side surface of the groove 101, and a first bevel gear 14 is sleeved on the bottom of the outer ring surface of the rotating shaft 13. A support plate 15 is sleeved on the top position of the outer ring surface of the rotating shaft 13, and a loading frame 16 is installed on the top of the rotating shaft 13. A card slot 161 is provided on the top of the loading frame 16, and manual bolts 17 are symmetrically installed on both ends of the outer side surface of the loading frame 16. A rotating rod 18 is installed at the center of the longer inner side surface of the groove 101, and a second bevel gear 19 is fixedly installed on one end of the rotating rod 18.

[0028] For example, please refer to Figure 1 , Figure 2 and Figure 3The output shaft of the forward and reverse motor 3 is fixedly connected to the center of the outer side surface of a transmission wheel 4, and the power transmission is realized between the two transmission wheels 4 through a belt. The center of the side surface of the two transmission wheels 4 that are in contact with the operation box 1 is respectively fixedly connected to one end of the two screw rods 11. The forward and reverse motor 3 is installed on the mounting frame 2 by bolts. After the forward and reverse motor 3 is started, it drives one transmission wheel 4 to rotate, and at the same time, the transmission wheel 4 drives the other transmission to rotate through the belt 5. The screw rod 11 is rotatably connected between the inner side surfaces of the groove 101, and threaded holes are opened at both ends of the two clamping rings 12. The two threaded holes on the two clamping rings 12 are respectively connected to the space between the two screw rods 11. It is a threaded connection, the top of the clamping ring 12 and the top of the support plate 15 are located on the same plane, and the thickness of the clamping ring 12 is the same as the thickness of the support plate 15. The support plate 15 is located on the inner side of the two clamping rings 12, and under normal conditions, the inner side surfaces of the two clamping rings 12 do not fit the outer ring surface of the support plate 15. Both ends of the screw rod 11 are designed with opposite thread teeth, and when the two clamping rings 12 move relative to each other and are spliced ​​together, the size of the inner side surface is smaller than the outer ring surface size of the support plate 15. The simultaneous rotation of the two transmission wheels 4 will drive the two screw rods 11 to rotate synchronously, and the two clamping rings 12 on the screw rod 11 will move close to each other to clamp the support plate 15.

[0029] For example, please refer to Figure 1 , Figure 2 and Figure 4 The L-shaped frame 7 is rotatably connected on the outer side of the operating box 1, and when the L-shaped frame 7 is rotated upward to a vertical state, the screw rod 8 is rotated clockwise to make the pressure block 9 move vertically downward and extend into the inner side of the groove 101. The pressure block 9 is made of rubber material. When the L-shaped frame 7 is not in use, it can be rotated to a parallel state, and the screw rod 8 is tightened to press the pressure block 9 against the outer side of the operating box 1. At this time, the L-shaped frame 7 does not hinder other operations of the device.

[0030] For example, please refer to Figure 1 , Figure 2 and Figure 3The rotating shaft 13 is rotatably connected at the bottom of the inner side of the groove 101, and the first bevel gear 14 and the support plate 15 are fixedly connected to the rotating shaft 13. The size of the slot 161 at the top of the loading frame 16 matches the width of the PCB board, and one end of the manual bolt 17 can be extended inside the slot 161 after being tightened clockwise, and the PCB board can be vertically inserted into the slot 161 and fixed by the manual bolt 17. At this time, the two welding surfaces of the PCB board are exposed to the outside at the same time, which is convenient for welding processing. One end of the rotating rod 18 passes through the outer side of the operation box 1 and is connected to the hand wheel 6, and the rotating rod 18 can rotate freely in the operation box 1, and the second bevel gear 19 at one end of the rotating rod 18 is meshed with the first bevel gear 14. By rotating the rotating rod 18 by the hand wheel, the second bevel gear 19 can drive the first bevel gear 14 to rotate, and drive the rotating shaft 13 to rotate, so as to realize the rotation adjustment of the orientation of the loading frame 16.

[0031] The working process of the utility model: using a PCB board welding tool designed by the scheme, when welding the PCB board, when welding the components whose welding points and components are on the same surface, the PCB board is placed flat on the top of the baffle 10 inside the groove 101, and then the two L-shaped frames 7 are rotated upward, and the screw rod 8 is rotated clockwise to make the pressing block 9 move vertically downward to squeeze and fix the top of the PCB board, and then the components can be welded;

[0032] When the welding point and the components are not on the same surface of the PCB board, the PCB board is vertically inserted into the slot 161 at the top of the loading frame 16, and then the manual bolt 17 is turned clockwise to fix the PCB board. At this time, both sides of the PCB board are exposed at the same time, and the welding pins can be inserted from one side to the other side, and then welding can be performed on the other side. It is very convenient and there is no need to flip the PCB board back and forth for operation. At the same time, the hand wheel 6 is turned to drive the first bevel gear 14 to rotate through the second bevel gear 19, and the rotating shaft is rotated at the same time. This is because the loading frame 16 will also rotate to adjust the orientation of the PCB board. After the position is adjusted, the forward and reverse motors 3 are started to drive the two screws 11 to rotate through the transmission wheel 4, so that the two clamping rings 12 move relative to each other to clamp the support plate 15 to prevent the loading frame 16 from rotating due to the inertia of the rotating shaft 13 during the welding process.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
