Detailed implementation manners

[0029] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0030] Embodiment 1

[0031] As Figure 1 、 Figure 4 and Figure 5As shown in the figure, a solder paste scraping device for the production of a heating plate includes a base 1 and a turntable 2. A rotating groove 101 is opened at the upper end of the base 1, and the turntable 2 rotates in the rotating groove 101. A second installation hole 104 is opened at the front side of the bottom wall of the rotating groove 101. An equipment groove 102 is opened inside the base 1. An installation opening 106 is opened on the left side of the equipment groove 102. A blanking hole 105 communicating with the equipment groove 102 is opened on the left side of the bottom wall of the rotating groove 101. A first installation hole 103 is opened on the right side of the bottom wall of the rotating groove 101. The area at the rear side of the bottom wall of the rotating groove 101 is the starting area for placing the heating plate. The position of the first installation hole 103 is the paste application area. The position of the second installation hole 104 is the scraping area. The position of the blanking hole 105 is the blanking area; Four circular holes 21 are evenly opened at the upper end of the turntable 2, and the circular holes 21 correspond to the first installation hole 103, the second installation hole 104, and the blanking hole 105. A tapered groove 22 is opened at the bottom of the side wall of the circular hole 21. A plurality of sliding grooves 23 are evenly opened on the side wall of the tapered groove 22. A fixing component 8 is installed in the tapered groove 22. A sheave structure 4 is installed in the equipment groove 102. A support 3 is fixedly installed on one side of the outer surface of the base 1. The support 3 includes a bottom plate 31, and the bottom plate 31 is fixedly installed outside the base 1. A plurality of support plates 34 are fixedly installed at the upper end of the bottom plate 31. The top of a plurality of the support plates 34 is fixedly installed with a top plate 33. The middle of a plurality of the support plates 34 is fixedly installed with a middle plate 32. A linkage device 5, a paste discharging component 6, and a scraping component 7 are installed on the support 3. The linkage device 5 is connected to the paste discharging component 6 and the scraping component 7. The paste discharging component 6 is located above the first installation hole 103. The scraping component 7 is located above the second installation hole 104. A discharge plate 9 is fixedly installed in the installation opening 106. The discharge plate 9 is located below the blanking hole 105. An inclined groove 91 is opened on the discharge plate 9. The inclined groove 91 is located below the blanking hole 105. The smeared heating plate falls into the inclined groove 91 through the blanking hole 105 and slides out along the inclined groove 91, thus completing the blanking work;

[0032] A plurality of first springs 10 are fixedly installed on the bottom walls of the first installation hole 103 and the second installation hole 104. A top block 11 is fixedly installed at the top of a plurality of the first springs 10. The diameter of the bottom opening of the tapered groove 22 is larger than the diameter of the top opening of the first installation hole 103 and the second installation hole 104. The top block 11 is in a frustum shape and can enter the tapered groove 22; The diameter of the top opening of the first installation hole 103 and the second installation hole 104 contracts inward to form an overall inverted conical structure, which is used to limit the frustum-shaped top block 11 from separating from the first installation hole 103 and the second installation hole 104. When the turntable 2 rotates, the side wall of the tapered groove 22 squeezes the top block 11, and the top block 11 squeezes the first spring 10 into the first installation hole 103 and the second installation hole 104, which will not affect the rotation of the turntable 2;

[0033] During use, place the heating plate in the circular hole 21 of the starting position turntable 2, then rotate 90° under the drive of the Geneva wheel structure 4 and intermittently stop. The turntable 2 drives the heating plate to reach above the first mounting hole 103 on the right side. Then, the first spring 10 presses the top block 11, and the top block 11 presses the fixing component 8, driving the fixing component 8 to clamp and fix the heating plate. At the same time, while the Geneva wheel structure 4 is working, it drives the scraping component 7 and the paste discharging component 6 to work through the linkage device 5. When the heating plate reaches below the paste discharging component 6, the paste discharging component 6 discharges the soldering paste onto the heating plate. Then, the Geneva wheel structure 4 continues to drive the turntable 2 to rotate 90° to reach the second mounting hole 104 on the front side. Then, the heating plate fixes the fixing component 8, and at the same time, the scraping component 7 starts to work, scraping the soldering paste on the surface of the heating plate evenly. When the Geneva wheel structure 4 continues to drive the turntable 2 to rotate 90°, the heating plate with the soldering paste applied reaches the blanking hole 105 on the left side and falls into the inclined groove 91, and completes the blanking along the inclined groove 91, thus completing a complete operation of applying soldering paste to the heating plate. In this way, through circular rotation, the Geneva wheel structure 4 drives the heating plates in the four circular holes 21 to perform paste discharging, scraping, and blanking operations in sequence, continuously performing the soldering paste application work on the heating plates, with high working efficiency.
