[0024] During installation, the staff can adjust the front and rear positions of the dispensing heads 16 by pulling the adjustment slide 15. After the front and rear positions are adjusted, the staff can adjust the position of the fixed slide 21 again as needed to adjust the lateral position of each dispensing head 16 individually. After the adjustment is completed, the staff rotates and tightens the bolt 23. Under the action of the thread of the screw barrel 22, the bolt 23 moves up and presses against the fixed seat 13 to fix it. This makes it convenient for the staff to adjust the position and spacing of the dispensing heads 16 as needed, so as to facilitate multi-point dispensing at different positions of the circuit board, thereby improving the scope of application to meet the dispensing needs of different circuit boards.

[0025] Further, such as Figure 3-4 As shown, a clamping seat 31 is fixedly connected to the side of the fixed slide 21; a pair of clamping jaws 33 are slidably connected to the clamping seat 31; a bidirectional screw 32 is rotatably connected to the middle part of the clamping seat 31; the bidirectional screw 32 passes through the clamping jaws 33 and is threadedly connected thereto; the dispensing head 16 is located between the pair of clamping jaws 33; during installation, the staff can rotate the bidirectional screw 32, and the two ends of the bidirectional screw 32 have threads with opposite thread directions, and rely on the bidirectional screw 32 to drive the two clamping jaws 33 to move on the clamping seat 31, so that they are opened or closed synchronously, so as to fix the dispensing head 16. Relying on the detachable structure, the dispensing head 16 can be easily installed and fixed.

[0026] Further, such as Figure 3-4As shown, a groove 41 is provided on one side where the two clamping jaws 33 are close to each other; a spring sheet 42 is fixed in the groove 41; the dispensing head 16 is located between a pair of spring sheets 42; the middle part of the spring sheet 42 is designed in a C-shaped structure; during installation, the dispensing head 16 can be pre-clamped and fixed by providing the spring sheet 42, and the staff only needs to insert the dispensing head 16 between the two spring sheets 42, and when the clamping jaws 33 are closed and fixed, the spring sheet 42 is deformed and enters the groove 41, and the clamping jaws 33 are in contact with the dispensing head 16 and fixed.

[0027] Further, such as Figure 3-4 As shown, one end of the two bidirectional screws 32 close to each other is fixedly connected to a transmission rod 52, and the other end of the bidirectional screw 32 is fixedly connected to a transmission sleeve 51; the transmission rod 52 is inserted into the interior of the transmission sleeve 51 and is slidably connected thereto; when in use, the transmission rod 52 is inserted into the transmission sleeve 51 and slides to form a retractable structure, which is mainly used for driving the other bidirectional screws 32 to rotate when one of the bidirectional screws 32 is rotated, so that multiple dispensing heads 16 can be fixed conveniently and the use of the staff is convenient.

[0028] Further, such as Figure 2-4 As shown, a non-slip metal plate 61 is fixed to the bottom of the fixing seat 13; a base 62 is fixed to the top of the bolt 23; a rubber pad 63 is fixed to the top side of the base 62; when in use, the non-slip metal plate 61 is a metal plate with non-slip patterns on the surface, and during the fixing process of the bolt 23, the rubber pad 63 on the base 62 is in contact with the non-slip metal plate 61, so that the bolt 23 can be fixed, thereby improving the fixing effect of the fixed slide seat 21 and reducing its movement.

[0029] Further, such as Figure 4 As shown, the elastic pads 7 are fixedly connected to the sides of the pair of spring pieces 42 that are close to each other. When in use, the elastic pads 7 can play a protective role and reduce the spring pieces 42 from scratching the surface of the dispensing head 16.

[0030] Working principle: during installation, the staff can adjust the front and rear position of the dispensing head 16 by pulling the adjustment slide 15. After the front and rear position adjustment is completed, the staff can adjust the position of the fixed slide 21 again according to the needs, so as to adjust the lateral position of each dispensing head 16 individually. After the adjustment is completed, the staff rotates and tightens the bolt 23. Under the action of the thread of the screw barrel 22, the bolt 23 moves up and presses against the fixed seat 13 to fix it. This makes it convenient for the staff to adjust the position and spacing of the dispensing head 16 according to the needs, so that it is convenient to perform multi-point dispensing at different positions of the circuit board, improve the scope of application, and meet the dispensing needs of different circuit boards. The staff can rotate the bidirectional screw 32, and the two ends of the bidirectional screw 32 have threads with opposite thread directions. Relying on the bidirectional screw 32, the two jaws 33 are driven to move on the clamping seat 31, so that they are opened or closed synchronously, so as to adjust the dispensing head 16. The dispensing head 16 can be fixed by the detachable structure, so that the dispensing head 16 can be conveniently installed and fixed. The dispensing head 16 can be pre-clamped and fixed by setting the spring sheet 42. The staff only needs to insert the dispensing head 16 between the two spring sheets 42. When the clamping jaws 33 are closed and fixed, the spring sheet 42 is deformed and enters the groove 41, and the clamping jaws 33 are contacted and fixed with the dispensing head 16. When in use, the transmission rod 52 is inserted into the transmission sleeve rod 51 and slides to form a retractable structure. It is mainly used for when one of the two-way screw rods 32 is rotated, it can drive the other two-way screw rods 32 to rotate, so that multiple dispensing heads 16 can be fixed conveniently, and the use of the staff is convenient. The anti-skid metal plate 61 is a metal plate with anti-skid patterns on the surface. During the fixing process of the bolt 23, the rubber pad 63 on the base 62 is in contact with the anti-skid metal plate 61, so that the bolt 23 can be fixed, thereby improving the fixing effect of the fixed slide 21 and reducing its movement.
