[0023] The following will be specifically described the specific settings and effects of the embodiment: under the movement of longitudinal shift component 6, horizontal shift component 3 and lifting assembly 4, needle tube 511 is close to component surface, second servo motor 51 is started, the power of second servo motor 51 is injected into belt drive assembly 52, so as to drive second screw 55 to rotate in the middle of connecting plate 54, connecting plate 54 obtains the moving force, moves linearly downward by second guide rail module 58, connecting plate 54 synchronously drives auxiliary rod 57 and pressing plug rod 56 to move linearly, auxiliary rod 57 is inserted into glass scale tube 59, which ensures that auxiliary rod 57 moves linearly stably without deviation, glass scale tube 59 is transparent and has scales outside, and the distance of linear movement can be displayed, pressing plug rod 56 and auxiliary rod 57 are in parallel state, so that the lower movable plug part of pressing plug rod 56 keeps linearly pressing into the inside of glue cylinder 510, stably applies pressure, ensures that glue is stably output from needle tube 511, and the scale reading between pressing plug rod 56 and glass scale tube 59 is the amount of glue in glue cylinder 510, which guides actual dispensing work.

[0024] Embodiment two: as Figure 1 - Figure 3As shown, the longitudinal moving assembly 6 comprises a connecting seat 61, a second bottom shell 62, a third guide rail module 63, a first lead screw 64 and a first servo motor 65. The connecting seat 61 is fixedly connected to one end of the transverse moving assembly 3. The other end of the transverse moving assembly 3 is slidably connected to the first bottom shell 1 through the first guide rail module 2. The connecting seat 61 is slidably connected to the bottom of the inner cavity of the second bottom shell 62 through the third guide rail module 63. The first servo motor 65 is fixedly connected to the bottom of the inner cavity of the second bottom shell 62. The first lead screw 64 is threadedly connected to the middle part of the connecting seat 61. One end of the first lead screw 64 is drivingly connected to the output shaft of the first servo motor 65.

[0025] The effect achieved by the whole embodiment is that when the component moves to the middle position of the frame composed of the first bottom shell 1, the transverse moving assembly 3 and the second bottom shell 62 on the conveying line, the first servo motor 65 is controlled to be started. The first servo motor 65 drives the first lead screw 64 to rotate in the middle part of the connecting seat 61. The component force generated by the rotation enables the connecting seat 61 to obtain force. Under the connecting action of the third guide rail module 63, the connecting seat 61 drives one end of the transverse moving assembly 3 to move inside the second bottom shell 62. Meanwhile, under the connecting action of the first guide rail module 2, the other end of the transverse moving assembly 3 moves synchronously inside the first bottom shell 1. Thus, the transverse moving assembly 3, the lifting assembly 4 and the dispensing assembly 5 move above the component.

[0026] The device is used and operates as follows: Install the device on the semiconductor component conveyor line. Glue is injected into the glue cartridge 510. When the component moves to the middle position of the frame composed of the first base shell 1, the transverse component 3, and the second base shell 62, the first servo motor 65 is activated. The first servo motor 65 drives the first lead screw 64 to rotate in the middle of the connecting seat 61. The meshing force generated by the rotation gives the connecting seat 61 force. Under the connection of the third guide rail module 63, the connecting seat 61 drives one end of the transverse component 3 to move inside the second base shell 62. Simultaneously, under the connection of the first guide rail module 2, the other end of the transverse component 3 moves synchronously inside the first base shell 1. Thus, the transverse component 3, the lifting component 4, and the dispensing component 5 move above the component. The transverse component 3 moves in the same manner as the longitudinal component 6, driving the lifting component... 4. The dispensing assembly 5 moves directly above the component. The lifting assembly 4 drives the needle tube 511 close to the surface of the component. Then, the second servo motor 51 is started. The power of the second servo motor 51 is injected into the belt drive assembly 52, thereby driving the second lead screw 55 to rotate in the middle of the connecting plate 54. The connecting plate 54 obtains the force to move and moves downward in a straight line with the help of the second guide rail module 58. The connecting plate 54 simultaneously drives the auxiliary rod 57 and the pressure rod 56 to move in a straight line. The auxiliary rod 57 is inserted into the glass scale tube 59, which ensures that the auxiliary rod 57 moves stably along the straight line without deviating. The glass scale tube 59 is transparent and has scales on the outside, which can also show the distance of the straight line movement. The pressure rod 56 and the auxiliary rod 57 are in a parallel state, so the movable plug part of the lower part of the pressure rod 56 is pressed into the glue cylinder 510 in a straight line, applying pressure stably and ensuring that the glue is stably output from the needle tube 511.
