DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Combination Figure 1 and Figure 2 As shown, an electronic component welding device described in an embodiment of the present invention comprises a base 1, a moving platform 2 is arranged on the top of the base 1, two support frames 3 are symmetrically fixedly connected to the top of the moving platform 2, and fixing components for PCB boards are arranged on the two support frames 3, a support frame 3 8 is fixedly connected to the top of the base 1, a welding component is arranged on the support frame 3 8, a protective frame 17 is fixedly connected to the middle of the support frame 3 8, a conveying frame 14 is fixedly connected to the bottom of the protective frame 17, a transmission belt 15 is arranged on the conveying frame 14, and a card slot 16 is evenly and equidistantly opened on the surface of the transmission belt 15, and a feeding component for pushing electronic components is arranged on one end of the protective frame 17 close to the base 1; when working, when uniformly welding resistors or diodes on the PCB board, the moving platform 2 moves on the base 1, which is conducive to driving the welding holes on the PCB board to move to the ends of the protective frame 17, and then the resistors or diodes are uniformly plugged into the card slots 16, and the conveying When the frame 14 drives the transmission belt 15 to convey the resistor to one end of the protective frame 17 close to the base 1, the conveying frame 14 temporarily stops driving the transmission belt 15 to move, and starts the feeding component. The feeding component conveys the resistor or diode upward, and the pins of the resistor or diode pass through the welding hole. Then the welding component is started, and the welding component welds the resistor or diode on the PCB board. The present invention adopts a method of conveying the electrode tube or resistor to the bottom of the PCB board, and conveying the resistor or diode upward by setting a feeding component so that its pins pass through the welding hole, instead of inserting the pins of the electronic components from the welding hole and extending them to a certain length from the back of the circuit board, and then turning the circuit board substrate so that the back side faces up, and then welding is performed. This is conducive to avoiding the situation that the diode and resistor will fall or slide downward due to vibration, gravity and other reasons, resulting in empty welding and irregular welding of the PCB board, which affects the welding quality of the PCB board.

[0035] It should be further explained that the mobile platform 2 can move horizontally and vertically on the base 1 so that the mobile platform 2 drives the PCB board to move. This technology is existing technology and will not be disclosed in detail here.

[0036] Combination Figure 1 and Figure 2 As shown, the welding assembly includes a lifting slot 9 and a cylinder 11. The lifting slot 9 is opened on the upper part of the support frame 3 8. A mounting plate 10 is slidably connected in the lifting slot 9. The cylinder 11 is fixedly connected to the top of the support frame 3 8. The telescopic rod of the cylinder 11 passes through the top of the support frame 3 8 and is fixedly connected to the mounting plate 10. A soldering iron tip 12 is fixedly connected to the bottom of the end of the mounting plate 10 away from the cylinder 11, and a welding wire 13 is arranged on one side of the soldering iron tip 12. During operation, after the PCB board is fixed by the fixing assembly, the welding of the diode or resistor is pushed through the welding hole on the PCB board by the feeding assembly, and then the cylinder 11 is started. The cylinder 11 drives the mounting plate 10 to descend, so that the soldering iron tip 12 and the welding wire 13 are close to the welding hole and the welding foot, and the diode or resistor is welded, which is conducive to the smooth progress of welding.

[0037] Combination Figure 1 and Figure 3 As shown, the fixing assembly includes a support frame 2 5, which is fixedly connected to the top of the support frame 1 3, and two cylinders 1 6 are fixedly connected to the top of the support frame 2 5. The telescopic rods of the two cylinders 1 6 pass through the top of the support frame 2 5 and are fixedly connected to a pressure plate 7 together; after the PCB board is placed on the support frame 1 3, the cylinder 1 6 is started, and the telescopic rod of the cylinder 1 6 drives the pressure plate 7 to descend, pressing the PCB board, which is helpful to avoid sliding of the PCB board during the movement of the mobile platform 2.

[0038] Combination Figures 1 to 6 As shown, the feeding assembly includes two slide grooves 25, and the two slide grooves 25 are symmetrically opened at one end of the protective frame 17 close to the base 1. Strip plates 26 are slidably connected in the two slide grooves 25, and the opposite ends of the two strip plates 26 are fixedly connected with clamping plates 27. The opposite ends of the two strip plates 26 are provided with top holding members, and the top holding members are used to push the strip plates 26 to move; when working, when the conveying frame 14 drives the transmission belt 15 to transport the resistor or diode to the end of the protective frame 17 close to the base 1, the conveying frame 14 temporarily stops driving the transmission belt 15 to move, and starts the top holding member. The top holding member first pushes the strip plate 26, so that the clamping plate 27 clamps the resistor or diode, and then pushes the resistor or diode upward, so that the welding feet of the resistor or diode pass through the welding holes on the PCB board, which is beneficial to the subsequent welding of the resistor or diode.

[0039] Combination Figures 6 to 9As shown, the top holding member includes a support block 18 and a protective shell 20, the protective shell 20 is fixedly connected to the end side wall of the protective frame 17, the bottom of the support block 18 is fixedly connected to a cylinder 3 19, the telescopic rod of the cylinder 3 19 passes through the support block 18 and the bottom of the protective shell 20 and is fixedly connected to a push block 21, the push block 21 is slidably connected in the protective shell 20, a straight groove 22 and an inclined groove 23 are fixedly opened on the side wall of the protective shell 20, the straight groove 22 and the inclined groove 23 are connected to each other, a cylindrical shaft 24 is slidably connected in the inclined groove 23, and the end of the cylindrical shaft 24 away from the inclined groove 23 is fixedly connected to the end of the strip plate 26 away from the clamping plate 27; when working, when the conveying frame 14 drives the transmission belt 15 to transport the resistor or diode to the end of the protective frame 17 close to the base 1 , the conveyor frame 14 temporarily stops driving the transmission belt 15 to move, and the cylinder three 19 is started. The telescopic rod of the cylinder three 19 moves to push the push block 21 upward, and the inclined groove 23 pushes the strip plate 26 to move into the protective frame 17 through the cylindrical shaft 24, so that the clamping plate 27 clamps the diode or resistor. After the cylindrical shaft 24 moves into the straight groove 22, the upward movement of the push block 21 no longer pushes the strip plate 26 to move into the protective frame 17. The upward movement of the push block 21 will push the strip plate 26 to move upward, so that the strip plate 26 drives the diode or resistor to be pushed upward through the clamping plate 27, which is beneficial to the welding of the diode or resistor through the welding hole on the PCB board, and is beneficial to the smooth welding of the PCB board and the diode or resistor.

[0040] Combination Fig. 9 and Fig.10 As shown, the end side wall of the protection frame 17 is provided with a second slide groove 29, and a limit plate 30 is slidably connected in the second slide groove 29. The side wall of the protection frame 17 is fixedly connected with a cylinder 4 31, and the telescopic rod of the cylinder 4 31 is fixedly connected to the limit plate 30. When working, before the cylindrical shaft 24 moves in the inclined groove 23, the cylinder 4 31 is started, and the cylinder 4 31 pushes the limit plate 30 to be stuck on the top of the strip plate 26. In the process of the inclined groove 23 of the push block 21 pushing the strip plate 26 to move through the cylindrical shaft 24, under the action of the limit plate 30, only the strip plate 26 is allowed to move. It moves toward the inside of the protective frame 17 and drives the clamping plate 27 to clamp the diode or resistor, which helps to prevent the strip plate 26 from moving upward when the inclined groove 23 pushes the strip plate 26 to move through the cylindrical shaft 24. After the cylindrical shaft 24 slides into the straight groove 22, the telescopic rod of the cylinder four 31 pulls the limit plate 30 to return to the initial position, which helps to prevent the limit plate 30 from affecting the push block 21 to push the strip plate 26 through the straight groove 22 to drive the diode or resistor upward, so that the pins of the diode or resistor pass through the welding holes on the PCB board.

[0041] Combination Figure 4 and Fig.11As shown, two infrared detectors 32 are symmetrically fixedly connected to the inner wall of the end of the protective frame 17; when working, the infrared detector 32 is at the same height as the top of the diode or resistor. When the diode or resistor moves to the infrared detector 32, if the infrared detector 32 can detect the diode or resistor, it means that the diode or resistor is accurately positioned and not tilted, which is convenient for the subsequent strip plate 26 and the clamping plate 27 to push the diode or resistor upward. If the infrared detector 32 does not detect the diode or resistor, it means that the diode is tilted, and the transmission belt 15 transports the diode or resistor forward, and the diode or resistor falls from the end of the transmission belt 15.

[0042] Combination Figure 4 and Figure 6 As shown, a limit rod 34 is fixedly connected between the two support blocks 18. During operation, the setting of the limit rod 34 facilitates the diode or resistor to be moved when the infrared detector 32 detects that the diode or resistor transmitted on the transmission belt 15 is tilted and when the diode or resistor is transmitted to the bottom surface of the end of the conveying rack 14, so as to facilitate the diode or resistor to fall out of the card slot 16.

[0043] Combination Figure 3 As shown, a board slot 4 is provided on the top of the support frame 3; when working, the PCB board is placed in the board slot 4. The setting of the board slot 4 is conducive to limiting the PCB board, which is conducive to the position accuracy of the PCB board, and further conducive to the position accuracy of the welding hole on the PCB board and the soldering iron tip 12.

[0044] Combination Figure 1 As shown, a material trough 35 is provided in the middle of the top of the moving platform 2; during operation, the material trough 35 is provided to facilitate collection and reuse of fallen diodes or resistors.

[0045] Working principle: When uniformly welding resistors or diodes on the PCB board, the moving platform 2 moves on the base 1, which is conducive to driving the welding holes on the PCB board to move to the end of the protective frame 17, and then the resistors or diodes are uniformly inserted into the card slots 16, and the conveyor frame 14 drives the transmission belt 15 to transport the resistors or diodes toward the end of the protective frame 17 close to the base 1.

[0046] When the diode or resistor moves to the infrared detector 32, if the infrared detector 32 can detect the diode or resistor, it means that the diode or resistor is accurately positioned and not tilted. If the infrared detector 32 does not detect the diode or resistor, it means that the diode is tilted.

[0047] When the infrared detector 32 detects a diode or a resistor, the cylinder three 19 is started, and the telescopic rod of the cylinder three 19 moves to push the push block 21 upward, and the inclined groove 23 pushes the strip plate 26 to move into the protective frame 17 through the cylindrical shaft 24, so that the clamping plate 27 clamps the diode or the resistor. After the cylindrical shaft 24 moves into the straight groove 22, the upward movement of the push block 21 no longer pushes the strip plate 26 to move into the protective frame 17. The upward movement of the push block 21 will push the strip plate 26 to move upward, so that the strip plate 26 drives the diode or the resistor to be pushed upward through the clamping plate 27, which is beneficial for the welding of the diode or the resistor through the welding hole on the PCB board, and is beneficial for the smooth welding of the PCB board and the diode or the resistor.

[0048] When the infrared detector 32 does not detect the diode or resistor, the transmission belt 15 transports the diode or resistor forward, and the diode or resistor falls from the end of the transmission belt 15. Through the setting of the limit rod 34, when the diode or resistor is transmitted to the bottom surface of the end of the conveying rack 14, the diode or resistor is moved, which is conducive to the diode or resistor falling from the card slot 16 and falling into the material trough 35, which is conducive to collecting and reusing the fallen diode or resistor.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
