[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-3 One embodiment of this utility model provides a preheater with scratch-resistant features, including a base plate 1. Two supports 2 are fixedly connected to the middle of the base plate 1. The supports 2 are fixed at the front and rear positions of the top center of the base plate 1. A heater 3 is fixedly connected to the top center of the base plate 1. A heating module 4 is fixedly connected to the top of the heater 3. A perforated plate 5 is fixedly connected to the top of the heating module 4. The heater 3 is connected to the heating module 4, and the electronic components are preheated through the heating module 4 and the perforated plate 5.
[0034] A positive electrode 6 is fixedly connected to the top center of the base plate 1. Three wires 7 are provided at the top of the positive electrode 6. The positive electrode 6 transmits positive current to the surface of the metal mask 8 through the wires 7. The metal mask 8 is fixedly connected to the top of the wires 7. Three wires 9 are fixedly connected to the front side of the metal mask 8. A negative electrode 10 is fixedly connected to the bottom of the wires 9. The negative electrode 10 transmits positive current to the surface of the metal mask 8 through the wires 9. When the positive and negative currents on the surface of the metal mask 8 come into contact at the top of the metal mask 8, a temporary magnetic field is generated, which attracts and fixes the electronic components placed on the metal mask 8.
[0035] Two button bases 11 are fixedly connected to the top center of the metal mask 8. Control wires are located inside the center of each button base 11, connecting to the positive terminal 6 and the negative terminal 10 respectively for activation. A collar 12 is slidably connected inside the button base 11, with a button 13 fixedly connected to its top. The button 13 is slidably connected to the inner wall of the button base 11, and a spring 14 is fixedly connected to its bottom. When the button 13 is pressed by electronic components, it descends, compressing the spring 14 and also pressing the control block in the center of the button base 11 to activate. At this time, the control block is electrically connected to the positive terminal 6 and the negative terminal 10 to emit positive and negative currents. Support blocks 15 are fixedly connected to the top left and right sides of the base plate 1. A cleaning component is located on the adjacent side of the two support blocks 15, which holds the cleaning component. The cleaning component is used to clean the surface of the electronic components on the metal mask 8.
[0036] refer to Figures 2-4The bottom end of the heating module 4 is fixedly connected to the front and rear sides of the top of the bracket 2. The bracket 2 supports the heating module 4 to preheat the electronic components smoothly. The bottom inner wall of the metal mask 8 is engaged with the outside of the heating module 4. The bottom end of the metal mask 8 is attached to the top of the perforated plate 5. The metal mask 8 is fitted over the perforated plate 5 and the heating module 4, and will not block the perforated plate 5 from heating the electronic components. The bottom end of the negative electrode 10 is fixedly connected to the front of the top of the base plate 1. The base plate 1 fixes the position of the negative electrode 10.
[0037] The negative electrode 10 is located at the front of the middle of the top of the base plate 1. An auxiliary frame 23 is fixedly connected to the front of the top of the base plate 1. A blocking mechanism 24 is slidably connected to the top of the auxiliary frame 23. The auxiliary frame 23 supports the sliding operation of the blocking mechanism 24. An auxiliary plate 25 is fixedly connected to the rear of the base plate 1. An infrared thermometer 26 is slidably connected to the top of the auxiliary plate 25. The auxiliary plate 25 supports the sliding operation of the infrared thermometer 26.
[0038] refer to Figure 3 , Figure 6 The cleaning assembly includes a motor 16, a rotating roller 17, a cross-loop pattern 18, a slider 19, a sliding member 20, an adjusting rod 21, and a brush plate 22. The motor 16 is fixedly connected to the right side of the left support block 15. The rotating roller 17 is fixedly connected to the drive end of the motor 16. The outside of the rotating roller 17 is rotatably connected to the middle of the two support blocks 15. When the motor 16 starts, it drives the rotating roller 17 to rotate in the middle of the support block 15. The outside of the rotating roller 17 is provided with a cross-loop pattern 18, which is a closed cross thread. The outside of the rotating roller 17 is slidably connected to the slider 19. The outside of the sliding member 20 is slidably connected to the inner wall of the cross-loop pattern 18.
[0039] The bottom end of slider 19 is slidably connected to the top end of base plate 1. The top middle part of slider 19 is rotatably connected to slider 20. The top end of slider 19 is fixedly connected to adjustment rod 21. The top end of adjustment rod 21 is fixedly connected to brush plate 22. When roller 17 rotates, slider 19 will be driven by slider 20 to slide back and forth outside roller 17. Since the top end of slider 19 is connected to brush plate 22 through adjustment rod 21 and brush plate 22 is suspended above the top of metal mask 8, when slider 19 slides, brush plate 22 slides back and forth with slider 19 to clean the surface of electronic components placed on the top of metal mask 8.
[0040] Working principle: When in use, when button 13 is pressed, it extends into the button base 11 and squeezes the control block in the middle of the button base 11. This controls the positive electrode 6 and line 1 7 to emit positive and negative currents into the metal cover 8 through line 1 7 and line 2 9. When the positive and negative currents come into contact, the metal cover 8 generates an adsorption force. The magnetic field generated by the positive and negative currents passing through the iron plate makes the metal cover 8 a temporary magnet. This magnetic field can interact with the magnetic field of nearby electronic components, thereby generating an adsorption force on the surface of the metal cover 8. At this time, the electronic components can be placed on the metal cover 8 and fixed, ensuring that the components will not move or become misaligned due to temperature changes or mechanical vibrations during the preheating process, effectively preventing the surface of the electronic components from being scratched.
[0041] After the electronic components are fixed, the motor 16 is controlled to start the rotating roller 17. Because the rotating roller 17 has a sliding member 20 connected to the cross-shaped loop 18, and the sliding member 20 is rotatably connected to the top of the inner wall of the slider 19 that slides outside the rotating roller 17, when the rotating roller 17 rotates, the slider 19 will be driven by the sliding member 20 to slide back and forth outside the rotating roller 17. Also, because the top of the slider 19 is connected to the brush plate 22 through the adjusting rod 21, and the brush plate 22 is suspended above the top of the metal cover 8, when the slider 19 slides, the brush plate 22 slides back and forth with the slider 19 to clean the surface of the electronic components placed on the top of the metal cover 8, effectively removing dust, oil and other impurities from the surface of the components, ensuring that dust and impurities will not be incorporated into the inside of the electronic components after heating.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
