The scraper 4 uses the arc surface 5 to coat the solder paste on the top surface of the circuit board body 3, and side plates are fixed on the front and rear ends of the scraper 4, the two side plates are arranged corresponding to the frame plates 2, and the side plates are fitted with the frame plates 2, and a slide 6 is arranged on the top of the scraper 4, and the front and rear ends of the slide 6 are respectively snapped on the top of the two frame plates 2, and the slide 6 moves left and right on the top of the frame plate 2. The circuit board body 3 is placed between the two racks 2, and the distance between the two racks 2 is adjusted by the regulating component, so that the two L-shaped racks 2 cooperate to clamp the circuit board body 3, and the top surface of the circuit board body 3 is in a horizontal state. After the solder paste is applied to the top surface of the circuit board body 3, when the slide 6 moves left and right on the top of the rack 2, the slide 6 drives the scraper 4 to move left and right synchronously by using the coating component. The scraper 4 that moves to the right uses the arc surface 5 on the left to smooth the solder paste on the top surface of the circuit board body 3. Similarly, the scraper 4 that moves to the left uses the arc surface 5 on the right to smooth the solder paste on the top surface of the circuit board body 3. When the scraper 4 moves in both directions, the scraper 4 uses the arc surface 5 to evenly spread the solder paste on the top surface of the circuit board body 3, thereby improving the efficiency of solder paste coating.

[0033] The process comprises the following steps:

[0034] S1. Use the regulating component to regulate the distance between the two racks 2. The two racks 2 cooperate to clamp the circuit board body 3. Use a stirring rod to stir the solder paste.

The lengths of the first pressure rod 7 and the second pressure rod 8 are the same, and the elastic force of the spring 11 makes the outer circumferential surface of the side rod 10 fit with the bottom surface of the convex edge 9. The first pressure rod 7 is pressed, and when the first pressure rod 7 moves downward inside the convex edge 9, the top end of the first pressure rod 7 cooperates with the convex edge 9 to squeeze the spring 11 on the left side, and the bottom end of the first pressure rod 7 that moves downward drives the side rod 10 on the left side to move downward, and the side rod 10 on the left side drives the scraper 4 to move downward on the left side. When the curved surface 5 on the left side of the straight scraper 4 corresponds to and fits with the top surface of the circuit board body 3, the first pressure rod 7 is stopped being pressed, and the spring 11 on the right side makes the side rod 10 on the right side fit with the bottom surface of the convex edge 9 on the right side, pushing the slide 6 to move right, and the slide 6 that moves right uses the convex edge 9 to drive the first pressure rod 7 and the second pressure rod 8 to move right. At this time, the curved surface 5 on the left side of the scraper 4 moves right on the top surface of the circuit board body 3.

[0038] Until the right end of the scraper 4 corresponds to the right end of the circuit board body 3, stop moving the slide 6, release the pressure applied to the top of the first pressure rod 7, press the second pressure rod 8, and while the second pressure rod 8 moves downward to squeeze the spring 11, the bottom end of the second pressure rod 8 uses the right side rod 10 to move the arc surface 5 on the right side of the scraper 4 downward until the arc surface 5 on the right side of the scraper 4 fits the top surface of the circuit board body 3. Push the slide 6 to move left, and the slide 6 that moves left uses the convex edge 9 to drive the first pressure rod 7 and the second pressure rod 8 to move left.

[0039] Through the bidirectional movement of the scraper 4, the two curved surfaces 5 of the scraper 4 can spread the solder paste flat on the top surface of the circuit board body 3, and the curved surfaces 5 at both ends of the scraper 4 correspond to the two ends of the left side of the circuit board body 3 respectively. When the curved surfaces 5 are at the top of the circuit board body 3, stop moving the scraper 4 to prevent the scraper 4 from pushing the solder paste out of the top surface of the circuit board body 3.

After the slide 6 is engaged and buckled on the surface of the limiting rod 12 by means of the slot 13, the slide 6 itself limits the two limiting rods 12 by means of the slot 13, so as to avoid changes in the distance between the two shelfs 2 and ensure the clamping stability of the circuit board body 3 between the two shelfs 2.

[0041] exist Figure 1 , Figure 4 and Figure 5 In the embodiment, the bottom of the frame 2 is fixed with a base frame 14 on both sides, and a connecting rod 15 is connected between the two base frames 14. The regulating component includes two rotating rods 16, and the two rotating rods 16 correspond to the two base frames 14 respectively. The ends of the rotating rods 16 spirally penetrate the center of the base frames 14. The rotating rotating rods 16 make the two opposite base frames 14 approach or move away from each other. A plurality of clamping plates 17 are fixed to the top surface of the bottom plate 1. The rotating rods 16 correspondingly penetrate the two clamping plates 17, and circular plates are fixed at both ends of the rotating rods 16. The two opposite clamping plates 17 correspond to the circular plates at both ends of the rotating rod 16 one by one. The rotating rod 16 rotates between the two clamping plates 17, and the circular plates at both ends of the rotating rod 16 prevent the rotating rod 16 from moving forward and backward during the rotation process.

[0042] The two rotating rods 16 are rotated synchronously. The rotating rotating rods 16 rotate inside the bottom frame 14. The rotating rotating rods 16 make the two opposite bottom frames 14 approach or move away from each other. The relative distance between the two shelf plates 2 is regulated by the spiral effect of the rotating rods 16 and the bottom frame 14.

[0043] exist Figure 5 and Figure 6 In the figure, a gear 18 is fixed at the center of the two rotating rods 16, and a belt 19 is rotatably sleeved on the outer sides of the two gears 18. A motor 20 is fixed on the top of the bottom plate 1, and a rotating gear 21 at the output end of the motor 20 meshes with the gear 18 on the left side. When the motor 20 is started, the output end of the motor 20 drives the gear 18 on the left side to rotate, and when the rotating gear 18 drives the adjacent gear 18 to rotate synchronously with the belt 19, the gear 18 drives the rotating rod 16 to rotate, that is, the two rotating rods 16 rotate synchronously.

[0044] exist Figures 4 to 8In the embodiment, the regulating component also includes two opposite side frames 22, the two ends of the side frames 22 are respectively sleeved on the surfaces of the two rotating rods 16, the two side frames 22 correspond one to one with the connecting rods 15 of the two frame plates 2, and a first rotating plate 23 and a second rotating plate 24 are arranged between the side frames 22 and the connecting rods 15. The top end of the first rotating plate 23 is hinged at the center of the side frames 22, and the bottom end of the second rotating plate 24 is hinged to the surface of the connecting rod 15. The top and bottom surfaces of the first rotating plate 23 and the top and bottom surfaces of the second rotating plate 24 are fixed with protrusions, the protrusion at the top of the second rotating plate 24 penetrates the protrusion at the top of the first rotating plate 23 through the insertion rod 25, and the protrusion at the bottom of the first rotating plate 23 penetrates the protrusion at the bottom of the second rotating plate 24 through the insertion rod 25, and nuts 26 are spirally sleeved on the surfaces of the two insertion rods 25, and the two nuts 26 are located between the first rotating plate 23 and the second rotating plate 24. Both ends of the rotating rod 16 are sleeved with elastic members 27, one end of the elastic member 27 is connected to the side frame 22, and the other end of the elastic member 27 is connected to the bottom frame 14. When the two frame plates 2 approach each other, the frame plate 2 moves on the surface of the rotating rod 16 by means of the bottom frame 14, that is, the bottom frame 14 gradually approaches the side frame 22. At this time, the bottom frame 14 and the side frame 22 cooperate to squeeze the elastic member 27 on the surface of the rotating rod 16. The elastic force of the elastic member 27 makes the gear 18 of the rotating rod 16 be at the center of the top surface of the bottom plate 1. When the bottom frame 14 approaches the side frame 22, the bottom frame 14 drives the connecting rod 15 to approach the side frame 22, and the connecting rod 15 drives the bottom end of the second rotating plate 24 to move. The bottom end of the second rotating plate 24 is close to the gear 18. Since the top of the second rotating plate 24 The protrusion at the top of the first rotating plate 23 is penetrated through the protrusion at the top of the first rotating plate 23 by the insertion rod 25, and the protrusion at the bottom of the first rotating plate 23 is penetrated through the protrusion at the bottom of the second rotating plate 24 by the insertion rod 25. The moving second rotating plate 24 drives the first rotating plate 23 to rotate by the two insertion rods 25, and the nut 26 on the surface of the top insertion rod 25 gradually approaches the protrusion at the top of the first rotating plate 23, and the protrusion at the bottom of the second rotating plate 24 gradually approaches the nut 26 on the surface of the bottom insertion rod 25, until the protrusion fits with the nut 26, and the second rotating plate 24 cannot continue to approach the gear 18. In the process of the two frame plates 2 cooperating to clamp the circuit board body 3, when the protrusion fits with the nut 26, the two frame plates 2 cooperate to clamp the circuit board body 3, and the spiral effect of the nut 26 and the insertion rod 25 is used to limit the distance between the first rotating plate 23 and the second rotating plate 24, so as to avoid the two frame plates 2 directly impacting the circuit board body 3, and to facilitate the protection of the circuit board body 3.

[0045] When the distance between the front and rear sides of the circuit board body 3 is small, the nut 26 is rotated, and the spiral effect of the nut 26 and the insertion rod 25 causes the nut 26 to move on the surface of the insertion rod 25, and the top nut 26 gradually approaches the protrusion on the top of the second rotating plate 24, and the bottom nut 26 gradually approaches the protrusion on the bottom of the first rotating plate 23, so that the two frame plates 2 can cooperate to clamp the circuit board bodies 3 of different widths, and at the same time avoid damage to the circuit board body 3 during the clamping process.

[0046] Working principle of the present invention:

[0047] Reference Figures 1 to 8 As shown, the circuit board body 3 is placed between the two frame plates 2, and the motor 20 is started. The motor 20 works by using the rotating gear 21 at the output end to drive the gear 18 on the left side to rotate. When the rotating gear 18 drives the adjacent gear 18 to rotate synchronously using the belt 19, the gear 18 drives the rotating rod 16 to rotate, that is, the two rotating rods 16 rotate synchronously. The two rotating rods 16 rotate synchronously, and the rotating rotating rods 16 rotate inside the bottom frame 14. The rotating rotating rods 16 make the two opposite bottom frames 14 approach or move away from each other, and the relative distance between the two frame plates 2 is regulated by the spiral effect of the rotating rod 16 and the bottom frame 14.

[0048] When the two racks 2 approach each other, the rack 2 moves on the surface of the rotating rod 16 by means of the bottom frame 14, that is, the bottom frame 14 gradually approaches the side frame 22. At this time, the bottom frame 14 and the side frame 22 cooperate to squeeze the elastic member 27 on the surface of the rotating rod 16. The elastic force of the elastic member 27 makes the gear 18 of the rotating rod 16 located at the center of the top surface of the bottom plate 1. When the bottom frame 14 approaches the side frame 22, the bottom frame 14 drives the connecting rod 15 to approach the side frame 22, and the connecting rod 15 drives the bottom end of the second rotating plate 24 to move. The bottom end of the second rotating plate 24 approaches the gear 18. Since the top of the second rotating plate 24 The protrusion at the top of the first rotating plate 23 is penetrated through the protrusion at the top of the first rotating plate 23 by the insertion rod 25, and the protrusion at the bottom of the first rotating plate 23 is penetrated through the protrusion at the bottom of the second rotating plate 24 by the insertion rod 25. The moving second rotating plate 24 drives the first rotating plate 23 to rotate by the two insertion rods 25, and the nut 26 on the surface of the top insertion rod 25 gradually approaches the protrusion at the top of the first rotating plate 23, and the protrusion at the bottom of the second rotating plate 24 gradually approaches the nut 26 on the surface of the bottom insertion rod 25, until the protrusion fits with the nut 26, and the second rotating plate 24 cannot continue to approach the gear 18. In the process of the two frame plates 2 cooperating to clamp the circuit board body 3, when the protrusion fits with the nut 26, the two frame plates 2 cooperate to clamp the circuit board body 3, and the spiral effect of the nut 26 and the insertion rod 25 is used to limit the distance between the first rotating plate 23 and the second rotating plate 24, so as to avoid the two frame plates 2 directly impacting the circuit board body 3, and to facilitate the protection of the circuit board body 3.

[0049] After applying the solder paste on the top surface of the circuit board body 3, press the first pressure rod 7. When the first pressure rod 7 moves downward inside the convex edge 9, the top end of the first pressure rod 7 cooperates with the convex edge 9 to squeeze the spring 11 on the left side, and the bottom end of the downwardly moved first pressure rod 7 drives the side rod 10 on the left side to move downward, and the side rod 10 on the left side drives the scraper 4 to move downward on the left side. When the arc-shaped surface 5 on the left side of the straight scraper 4 corresponds to and fits with the top surface of the circuit board body 3, stop pressing the first pressure rod 7, and the spring 11 on the right side makes the side rod 10 on the right side fit with the bottom surface of the convex edge 9 on the right side, pushing the slide 6 to move right. The right-moving slide 6 uses the convex edge 9 to drive the first pressure rod 7 and the second pressure rod 8 to move right. At this time, the arc-shaped surface 5 on the left side of the scraper 4 moves right on the top surface of the circuit board body 3. Until the right end of the scraper 4 corresponds to the right end of the circuit board body 3, stop moving the slide 6, release the pressure applied to the top of the first pressure rod 7, press the second pressure rod 8, and while the second pressure rod 8 moves downward to squeeze the spring 11, the bottom end of the second pressure rod 8 uses the right side rod 10 to move the arc surface 5 on the right side of the scraper 4 downward until the arc surface 5 on the right side of the scraper 4 fits the top surface of the circuit board body 3. Push the slide 6 to move left, and the slide 6 that moves left uses the convex edge 9 to drive the first pressure rod 7 and the second pressure rod 8 to move left. At this time, the arc surface 5 on the right side of the scraper 4 moves left on the top surface of the circuit board body 3.

[0050] When the slide 6 moves left and right on the top of the frame plate 2, the slide 6 uses the coating component to drive the scraper 4 to move left and right synchronously. The scraper 4 that moves to the right uses the curved surface 5 on the left to smooth the solder paste on the top surface of the circuit board body 3. Similarly, the scraper 4 that moves to the left uses the curved surface 5 on the right to smooth the solder paste on the top surface of the circuit board body 3. When the scraper 4 moves in both directions, the solder paste can be evenly spread on the top surface of the circuit board body 3, thereby improving the efficiency of solder paste coating.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
