[0002] The solder paste brush machine, also known as the solder paste printer, is generally composed of a chassis, a CNC board, a base, a pedestal, a mobile frame, a brush plate, a printing screen and other mechanisms. Usually, the circuit board to be printed is placed on the pedestal, and then the left and right scraper brush plates of the printer print the solder paste through the printing screen onto the corresponding pads. It is widely used in the electronic components industry.

[0003] The above-mentioned and existing related technologies often have the following defects: when personnel place the circuit board on the base and print the solder paste, they usually use it together with the screen printing. Personnel usually directly place the circuit board on the base and manually position it by visual observation, which makes it difficult to accurately align it under the screen printing, resulting in a certain deviation, thus causing the problem that the solder paste cannot be accurately printed on the required patch position of the circuit board.

[0004] Therefore, we propose a positioning device for the production and processing of solder paste brush machines. Utility Model Content

[0030] The specific arrangement and function of the positioning structure 8 and the auxiliary structure 9 will be described in detail below.

[0031] like Figure 1 and Figure 2 as well as Figure 3 As shown, the positioning structure 8 includes two side grooves 801, and the two side grooves 801 are both opened on the upper surface of the base 4. The inner wall of the side groove 801 is fixedly connected with a screw rod 802, and the arc surface of the screw rod 802 is threadedly connected with a screw tube 803. The arc surface of the screw rod 802 is slidably connected with a positioning plate 804, and one side of the positioning plate 804 abuts against the screw tube 803. The inner wall of the side groove 801 relative to the two sides of the screw rod 802 is fixedly connected with a connecting plate 805, and the side of the connecting plate 805 close to the positioning plate 804 is fixedly connected with a spring 806, and the other end of the spring 806 is fixedly connected to the positioning plate 804. The positioning plate 804 moves to make the spring 806 expand and contract, and the spring 806 plays an auxiliary role in fixing. The positioning plate 804 has a function that one side of the screw tube 803 away from the positioning plate 804 is fixedly connected to two connecting rods 807, and the other ends of the two connecting rods 807 are fixedly connected to a ring 808. The rotating ring 808 drives the screw tube 803 to rotate with the help of the connecting rod 807, and the ring 808 achieves the effect of facilitating the rotation of the screw tube 803. One side of the positioning plate 804 is fixedly connected to a benchmark 809, and an inner groove is provided on the upper surface of the base 4. A benchmark plate 810 is fixedly connected to the inner wall of the inner groove. The benchmark 809 is located above the benchmark plate 810. The positioning plate 804 drives the benchmark 809 to move from above the benchmark plate 810, and the benchmark plate 810 serves to facilitate personnel to observe the moving distance of the positioning plate 804.

[0032] like Figure 1 and Figure 2 as well as Figure 4As shown, the auxiliary structure 9 includes an L-shaped hole 91, which is provided on the surface of the base 4. An L-shaped plate 92 is slidably connected to the inner wall of the L-shaped hole 91. A push rod 93 is fixedly connected to the long arm of the L-shaped plate 92. The push rod 93 is located at the position of the short arm of the L-shaped hole 91. A circular hole 95 is provided on the short arm of the L-shaped plate 92. A slide rod 94 is slidably connected to the inner wall of the circular hole 95. The lower end of the slide rod 94 is fixedly connected to the base 3. The L-shaped plate 92 moves to make the circular hole 95 slide on the arc surface of the slide rod 94. The slide rod 94 serves to locate the moving path of the L-shaped plate 92. A protective pad 96 is fixedly connected to the upper surface of the push rod 93. The protective pad 96 is a silicone pad. The push rod 93 is attached to the circuit board with the help of the protective pad 96. The protective pad 96 serves to prevent the push rod 93 from directly contacting and colliding with the components of the circuit board and damaging them.

[0033] Working principle: When solder paste printing is required on the circuit board, the ring 808 is first rotated, and the connecting rod 807 drives the screw tube 803 to rotate and move from the arc surface of the screw rod 802 through the ring 808. The positioning plate 804 slides from the arc surface of the screw rod 802 through the rotation of the screw tube 803. At this time, the spring 806 is in a stretched state due to the movement of the positioning plate 804. The spring 806 plays a role in assisting the fixing of the positioning plate 804. After the mark rod 809 moves from the top of the mark plate 810 to a suitable position through the positioning plate 804, the mark plate 810 plays a role in facilitating the personnel to observe the moving distance of the positioning plate 804. The ring 808 is loosened, and the ring 808 is convenient for rotating the screw tube 80 3, at this time, the positioning plate 804 is moved and positioned in the side groove 801, and then the circuit board is placed between the two positioning plates 804 on the upper surface of the base 4, and then the printing screen 7 is limited under the brush plate 6 through the movable frame 5, and the solder paste is leaked through the printing screen 7 on the corresponding pads on the upper surface of the circuit board through the left and right scraper brush plates 6. At this time, the printing of the circuit board is completed, and then the circuit board is ejected and removed through the auxiliary structure 9, and other circuit boards are placed to continue printing according to the above operations. The positioned positioning plate 804 allows the personnel to keep the position of the circuit board uniform each time it is placed, thereby improving the accuracy between the circuit board and the printing screen 7 leak printing and the integrity of the solder paste coverage of the circuit board itself.

[0034] When it is necessary to remove the printed circuit board, first move the short arm of the L-shaped plate 92 to the side away from the base 3, and the circular hole 95 of the short arm of the L-shaped plate 92 slides from the arc surface of the slide bar 94. The slide bar 94 serves to locate the moving path of the L-shaped plate 92, and the long arm of the L-shaped plate 92 slides in the long arm of the L-shaped hole 91. The push rod 93 rises in the short arm of the L-shaped hole 91 through the movement of the L-shaped plate 92, thereby driving the protective pad 96 to fit with the circuit board. The protective pad 96 prevents the push rod 93 from direct contact and collision with the circuit board components to damage them. Then the circuit board is ejected and separated from the base 4, so as to facilitate personnel to quickly take out the circuit board.
