Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 4 , the present invention provides a technical solution:

[0026] An automatic spot welding machine includes a bottom plate 1,

[0027] A connecting seat 101 is installed at the front end of the top of the bottom plate 1, and a fixed frame 6 is installed at the back end of the top of the bottom plate 1. A first electric guide rail 7 is installed at the top of the fixed frame 6. A connecting plate 701 is installed at the moving end of the first electric guide rail 7. A second electric guide rail 10 is fixedly installed at one end of the connecting plate 701. Two groups of slide plates 9 are installed below the back of the second electric guide rail 10. One end of the slide plate 9 is slidably connected to the inside of the corresponding sliding groove 8 opened above the front of the fixed frame 6;

[0028] The output end of the second electric guide rail 10 is installed with a mounting plate 11 that is convenient for moving up and down. One end of the front of the mounting plate 11 is installed with a mounting seat 12. There are three groups of spot welding machine bodies 13 for spraying solder on one side of the mounting seat 12. The bottom of the three groups of spot welding machine bodies 13 is installed with a discharge end 14. A spray pipe 15 for solder spraying is movably installed on one side of the discharge end 14, and two spray pipes 15 are provided at one end of each discharge end 14;

[0029] By setting the above three groups of spot welding machine bodies 13, the present invention is convenient for spraying solder on the three groups of electronic components, so as to improve the efficiency of spraying solder on the electronic components.

[0030] By starting the second electric guide rail 10, the output end thereof drives the three groups of soldering machine bodies 13 arranged on the mounting plate 11 to adjust the height, so that after the spray pipe 15 for spraying solder on the soldering machine body 13 is adjusted to a position suitable for spraying solder on the electronic component, the work is stopped. Then, by starting the first electric guide rail 7, the output end thereof drives the connecting plate 701 to move back and forth, so that the connecting plate 701 indirectly drives the soldering machine body 13 to move back and forth, thereby making the spray pipe 15 penetrate into and away from the electronic component. After penetrating into the electronic component, the soldering machine body 13 is started to make the spray pipe 15 thereon spray solder. While spraying solder, at this time, the first electric guide rail 7 drives the spray pipe 15 away from the electronic component, thereby realizing automatic spraying of solder on the electronic component.

[0031] A support seat 16 is installed below the center of the front surface of the mounting plate 11, and guide holes corresponding to the same number as the spray pipes 15 are provided inside the support seat 16; by providing the support seat 16 and the guide holes, it is convenient to support and fix the spray pipes 15.

[0032] Above the connecting seat 101 is provided a workbench 3, and a limiting seat 4 is installed at one end of the top of the workbench 3. A limiting guide groove 401 corresponding to the spray pipe 15 is provided on the top surface of the limiting seat 4. At one end of the limiting seat 4 are provided three groups of positioning seats 5 for positioning and fixing the electronic component. Four surrounding sides of the bottom of the workbench 3 are fixedly installed with support rods 202, and a fixing column 201 is installed at the bottom of the support rod 202. The fixing column 201 is clamped in a corresponding fixing groove 2 provided on the top of the connecting seat 101, and the fixing column 201 and the fixing groove 2 are adapted to each other.

[0033] In this utility model, by using components such as the workbench 3, the limiting seat 4, the limiting guide groove 401 and the positioning seat 5 in cooperation, it is convenient to position and install the electronic component during spraying solder, so as to improve the accuracy of the electronic component when being sprayed with solder by the spray pipe 15; at the same time, by using components such as the limiting seat 4 and the limiting guide groove 401 in cooperation, it is convenient to improve the accuracy and stability of the spray pipe 15 inserted into the electronic component for spraying solder.

[0034] By hand, take the workbench 3, and move the fixing column 201 on its bottom upward out of the fixing groove 2 provided on the connecting seat 101, so that the workbench 3 can be disassembled from the connecting seat 101 for cleaning and replacement.

[0035] One side of the fixing frame 6 is provided with a control seat 17, and a pressure gauge 18 is installed above the surface of the control seat 17. The pressure gauge 18 is used to display the air pressure value in the pneumatic system. It is usually connected to the pipeline between the air source and the discharge end 14 so that the operator can monitor the air pressure in real time, ensure that the air pressure is within an appropriate range, and thus ensure the normal operation of the spray nozzle 15 for spraying solder; a back suction valve 19 is installed at the center of the surface of the control seat 17. The back suction valve 19 is used to control the flow of solder. After the soldering operation is completed, the back suction valve 19 can be quickly closed to prevent the solder from flowing out continuously, thereby avoiding waste of solder.

[0036] A pressure regulating valve 20 is installed below the surface of the control seat 17. The pressure regulating valve 20 is used to regulate the air pressure in the pneumatic system. It allows the operator to adjust the air pressure according to needs to adapt to different soldering tasks. A connecting hose 21 is movably installed at the top of the control seat 17. One end of the connecting hose 21 is provided with a number of branch pipes, and one end of the branch pipe is movably installed with the discharge end 14 on the soldering machine body 13.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
