Technical Field

[0002] The chip transistor is an electronic component with three electrodes: collector (input electrode), base (control electrode), and emitter (output electrode). Based on the material and operating frequency of the chip transistor, the chip transistor is usually divided into amplifier tubes and switching tubes. The amplifier tube can amplify the current coefficient, and the switching tube can be used as an electronic switch, and can be used with other electronic components to form an oscillator, etc.

[0003] When using chip transistors, they need to be soldered to the pins of other electronic components. In existing technologies, chip transistors and electronic components are usually soldered manually. The manual soldering method cannot accurately control the soldering position, which may cause the soldering position to shift, thereby affecting the working efficiency of the chip transistor and even causing it to be scrapped.

[0004] Therefore, the present invention needs to design a foot patch mount that is easy to weld. Utility Model Content

A bidirectional screw is fixedly connected to the output shaft of the servo motor. Fixed plates are slidably provided on the left and right sides of the limit plate, and the two fixed plates are respectively threadedly connected to the two sides of the bidirectional screw. The left and right sides of the top front side of the support plate are fixedly installed, and a push plate is fixedly installed between the ends of the two cylinder piston rods. Slide blocks are fixedly installed on the lower parts of the left and right ends of the push plate, and slide rails are fixedly installed on the left and right sides of the support plate, and the slider is slidably installed on the slide rails.

[0009] More preferably, the edge of the groove is inclined.

[0010] More preferably, the extrusion plate is made of rubber.

[0012] More preferably, an extrusion plate and a spring are further included, the extrusion plate is slidably provided on the push plate between the three grooves, and a spring is connected between the extrusion plate and the push plate.

[0013] Compared with the existing technology, the utility model has the following advantages: 1.

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: A foot patch device that is easy to solder, such as Figure 1-5 As shown, it includes a support plate 1, a support frame 2, a limit plate 3, an electric push rod 4, a connecting plate 5, a welding gun 6, a servo motor 7, a bidirectional screw 8, a fixed plate 9, a cylinder 10, a push plate 11, a slider 12 and a slide rail 13. The support frame 2 is installed on the upper rear side of the support plate 1 by screws. The limit plate 3 is welded to the bottom of the support frame 2. The electric push rod 4 is slidably installed on the top of the support frame 2. The connecting plate 5 is fixedly connected to the piston rod at the lower end of the electric push rod 4. Three welding guns 6 are installed on the connecting plate 5 by screws. The servo motor 7 is fixedly connected to the output shaft of the servo motor 7. The limit plate 3 slides on both sides. A fixed plate 9 is provided, and the two fixed plates 9 are respectively threadedly connected to the two sides of the bidirectional screw 8. The left and right sides of the top front side of the support plate 1 are installed with a cylinder 10 by screws. A push plate 11 is fixedly installed between the ends of the piston rods of the two cylinders 10. Slide blocks 12 are installed on the lower parts of the left and right ends of the push plate 11 by screws. Slide rails 13 are installed on the left and right sides of the support plate 1 by screws. The sliders 12 are slidably installed on the slide rails 13. The welding gun 6 is vertically facing the foot patch to be welded. A pin groove corresponding to the patch transistor is opened on the push plate 11, and the edge of the groove is inclined. The extrusion plate 14 is made of rubber. The two fixed plates 9 are Y-shaped when close to each other.

[0023] like Figure 3 As shown, an extrusion plate 14 and a spring 15 are also included. The extrusion plate 14 is slidably provided on the push plate 11 between the three grooves, and the spring 15 is fixedly connected between the extrusion plate 14 and the push plate 11.

[0024] This device is used when it is necessary to solder the chip transistor. First, place the support plate 1 horizontally on the workbench, place the chip transistor to be soldered between the two fixing plates 9, so that the rear end of the chip transistor is attached to the limit plate 3, and then start the servo motor 7. The bidirectional screw 8 on the servo motor 7 rotates to move the two fixing plates 9 toward the middle at the same time until the chip transistor is fixed on the support plate 1. Then turn off the motor. After the chip transistor is fixed, start the two cylinders 10. The output shaft of the cylinder 10 drives the push plate 11 upward. The slider 12 slides on the slide rail 13. When the extrusion plate 14 on the push plate 11 contacts the chip transistor, the spring 15 is compressed. At this time, the two cylinders 10 are stopped, and the pins of the electronic components to be welded are placed in the grooves on the push plate 11 so that the pins are located directly above the chip transistor. At this time, the electric push rod 4 on the support frame 2 is started, and the connecting plate 5 moves downward under the push of the electric push rod 4. When the welding gun 6 is located above the pins to be welded, the electric push rod 4 is stopped. At this time, the pins of the electronic components and the chip transistor are welded.

[0025] After welding is completed, start the electric push rod 4 to reset the connecting plate 5 and the welding gun 6 on the electric push rod 4, then start the servo motor 7 to reverse the rotation of the bidirectional screw 8 to separate the fixed plate 9 from the SMD transistor. At this time, take away the welded electronic components and the SMD transistor, start the two cylinders 10 again, and make the push plate 11 slide and reset on the slide rail 13, completing the welding of the SMD transistor and the electronic component pins.
