[0015] Compared with the prior art, the technical effects achieved by the embodiments of this utility model include:
[0016] This utility model embodiment utilizes a structure including a set screw, an inverted L-shaped plate, a spring, a slider, and a contact sensor. First bolts are installed in the first and second mounting holes, and the mounting block and inverted L-shaped plate are fixed by these bolts. The connecting block and slider are fixed by screwing a positioning screw into the positioning screw hole. The bottom bracket is fixed to the inverted L-shaped plate by fixing screws. The dispensing module is mounted on the dispensing arm via the mounting block. As the machine moves, the dispensing needle picks up silver paste and moves to the component placement area. The equipment drives the dispensing module downwards, and the dispensing needle contacts the placement position, completing the dispensing process. The downward movement of the dispensing needle contacts... When the spring moves upward on the object's surface, it causes the slider to move upward. The force exerted by the spring on the slider is the dispensing force. There is a set screw at the top of the spring. By adjusting the depth of the set screw into the threaded hole, the deformation of the spring can be adjusted, thereby adjusting the force exerted by the spring on the slider. Using a tension meter or other force measuring instrument, the dispensing needle is slowly lifted upward. When the force exceeds the spring force, the bottom support and the slider will lose contact, and the contact sensor will alarm. The upward lifting force measured by the instrument is the dispensing force, which solves the problem of poor dispensing force control of existing dispensing sleeves and dispensing needles.

[0033] Please see Figure 1-8This utility model provides a novel dispensing module, including an inverted L-shaped plate 9. A fixing block 15 is fixedly installed through the top of the inverted L-shaped plate 9. The bottom of the fixing block 15 is flush with the bottom of the upper end of the inverted L-shaped plate 9. A threaded hole 8 is installed through the top of the fixing block 15. A set screw 1 is installed in the threaded hole 8 and threadedly engaged with the threaded hole 8. A spring 3 is installed at the bottom of the upper end of the inverted L-shaped plate 9. The top of the spring 3 is fixedly connected to the set screw 1. A slider 4 is fixedly installed at the bottom of the spring 3. The slider 4 slides up and down on the lower inner wall of the inverted L-shaped plate 9. A connecting block 5 is installed on the side of the slider 4 away from the inverted L-shaped plate 9. A bottom bracket 6 is installed at the bottom end of the inverted L-shaped plate 9. A contact sensor 18 is fixedly installed on the bottom bracket 6. The contact sensor 18 is located directly below the slider 4. A dispensing plate 12 is fixedly installed on the lower outer wall of the connecting block 5. A dispensing needle 14 is installed below the dispensing plate 12.
[0034] Furthermore, a mounting block 7 is provided on the side wall of the inverted L-shaped plate 9. A dotted arm is installed on the top of the mounting block 7. A first mounting hole 20 is opened on the outer wall of the mounting block 7. A second mounting hole 2 is opened on the upper outer wall of the inverted L-shaped plate 9. The first mounting hole 20 and the second mounting hole 2 are set one-to-one. A first bolt is set in the first mounting hole 20 and the second mounting hole 2. The mounting block 7 and the inverted L-shaped plate 9 are fixed by the first bolt. An adjustment hole is opened on the top of the set screw 1. The adjustment hole is square. A gap is left between the mounting block 7 and the slider 4. A groove 10 is opened on the outer wall of the connecting block 5. A positioning hole 11 is opened through the upper and lower ends of the inner wall of the groove 10. A positioning screw is set in the positioning hole 11. A positioning screw hole is opened on the side of the slider 4 near the connecting block 5. The positioning screw is threaded with the positioning screw hole. The connecting block 5 and the slider 4 are fixed by screwing the positioning screw into the positioning screw hole. A fixing hole 16 is opened on the bottom of the bottom bracket 6. The bottom bracket 6 and the inverted L-shaped plate 9 are fixed by fixing screws.
[0035] The dispensing module structure of this utility model is installed on the dispensing arm by mounting block 7. Under the movement of the machine, the dispensing needle 14 dips into the silver paste and then moves to the component mounting area. The equipment drives the dispensing module to move downward, and the dispensing needle 14 contacts the mounting position to complete the dispensing. When the dispensing needle 14 moves downward and contacts the object surface, it will drive the slider 4 to move upward. At this time, the force of the spring 3 acting on the slider is the dispensing force. There is a set screw 1 at the top of the spring 3. By adjusting the depth of the set screw 1 screwed into the threaded hole 8, the deformation of the spring 3 can be adjusted, thereby adjusting the force applied by the spring 3 to the slider 4. Using a tension meter or other force measuring instrument, the dispensing needle 14 is slowly lifted upward. When the force is greater than the force of the spring 3, the bottom bracket 6 and the slider 4 will disconnect. At this time, the contact sensor 18 will alarm. The upward lifting force measured by the instrument is the dispensing force, which solves the problem of poor control of the dispensing force of the existing dispensing sleeve dispensing needle.
[0036] Please continue reading. Figure 5 As an improvement to the above technical solution, a dispensing rod 17 is installed at the bottom of the dispensing plate 12, and a nut 13 is threaded on the lower end of the dispensing rod 17. A dispensing needle 14 is detachably installed at the bottom of the nut 13. The longitudinal section of the dispensing plate 12 is set in an inverted L shape. The nut 13 is made of stainless steel, which is not easy to rust and can be used for a long time.
[0037] In this invention, a locking hole (not shown) is provided at the bottom of the nut 13, and the dispensing needle 14 is locked in the locking hole. A sleeve block 19 is fixedly provided at the bottom of the dispensing plate 12, and the sleeve block 19 is fixedly sleeved on the dispensing rod 17. Through the structure of the nut 13, sleeve block 19 and dispensing rod 17, the sleeve block 19 is fixed at the bottom of the dispensing plate 12, which improves the firmness of the connection between the dispensing rod 17 and the dispensing plate 12. When it is necessary to replace the dispensing needle 14, the nut 13 is removed by rotating counterclockwise, the dispensing needle 14 is taken out, the corresponding dispensing needle 14 is replaced and locked in the locking hole, and the nut 13 is rotated clockwise to complete the installation. The installation is simple and quick, and can be completed in 10 seconds. This solves the problem of complicated installation and difficult disassembly of the dispensing needle of the existing dispensing sleeve.
