[0041] See also Figure 1 and Figure 2 The present embodiment provides a vacuum glue dispensing machine, which includes a vacuum box 1, a feed door 2, a discharge door 3, a glue dispensing valve 4, a transfer mechanism 5, a carrying platform 6 and a driving mechanism 7.

[0042] In this embodiment, the vacuum box 1 is arranged in a rectangular parallelepiped shape, and the vacuum box 1 includes a vacuum chamber 11. The feed door 2 and the discharge door 3 are respectively arranged on both sides of the vacuum box 1 along the Y direction, so that both sides of the vacuum chamber 11 can be connected to the outer space. Preferably, the feed door 2 and the discharge door 3 are both lifting doors. Such an arrangement can reduce the space occupied by the feed door 2 and the discharge door 3 when they are opened, and can make the vacuum glue filling machine more compact.

[0043] It should be noted that the vacuum box 1 is a prior art, and includes a supporting mechanism for vacuuming, which will not be described in detail in this embodiment. It should also be noted that the lifting door is preferably a lifting door with a sealing structure in the prior art.

[0044] Further, the dispensing valve 4 is arranged in the vacuum box 1 and is located at the upper part of the vacuum chamber 11. The transfer mechanism 5 is arranged in the vacuum box 1, and the transfer mechanism 5 is configured to drive the dispensing valve 4 to move in the X direction and the Y direction, and the X direction and the Y direction are perpendicular to each other. The carrying platform 6 is arranged in the vacuum box 1 and is located below the dispensing valve 4, and the carrying platform 6 is used to carry the product. The driving mechanism 7 is arranged on the outside of the vacuum box 1, and the driving mechanism 7 is configured to drive the carrying platform 6 to move along the Z direction, and the X direction, the Y direction and the Z direction are all perpendicular to each other.

[0045] In actual applications, the feed door 2 is opened first, the product is fed into the vacuum chamber 11 and placed on the carrying platform 6, then the feed door 2 is closed, the vacuum chamber 11 starts to be evacuated, and then the driving mechanism 7 drives the carrying platform 6 to rise along the Z direction, and the transfer mechanism 5 drives the dispensing valve 4 to move in the XY direction. The dispensing valve 4 supplies the colloid to multiple positions of the product. After the colloid supply is completed, the transfer mechanism 5 drives the dispensing valve 4 to reset, and the driving mechanism 7 drives the carrying platform 6 to reset, the vacuum chamber 11 is unloaded, and then the discharge door 3 is opened, and finally the product is sent out of the vacuum chamber 11.

[0046] It can be understood that by driving the carrying platform 6 to move along the Z direction through the driving mechanism 7 arranged on the outside of the vacuum box 1, the position of the product can be adjusted in the Z direction, so that the transfer mechanism 5 only needs to drive the dispensing valve 4 to move in the X direction and the Y direction. Compared with the motion mechanism in the prior art that drives the dispensing valve 4 to move in three directions of XYZ, the transfer mechanism 5 has a simpler structure and occupies less space, thereby making the space of the vacuum chamber 11 small and the use cost low. It can also reduce the vacuuming time and improve production efficiency.

[0047] It should be noted that the transfer mechanism 5 can adopt any structure in the prior art that can realize driving in the X direction and the Y direction, so it will not be described in detail. In addition, the dispensing valve 4 is selected according to the actual application scenario, and this embodiment does not make specific requirements and restrictions on this.

The upper side of the guide shaft 71 extends into the vacuum chamber 11 and is connected to the bearing platform 6. Such an arrangement can make the bearing platform 6 move more smoothly. It should be noted that the guide shaft 71 and the guide sleeve 72 are both prior arts. In this embodiment, two guide shafts 71 are provided, and two guide sleeves 72 are correspondingly provided. The two guide shafts 71 are respectively connected to the two ends of the bearing platform 6, so that the bearing platform 6 moves more smoothly.

[0050] Preferably, a sealing ring is provided between the guide sleeve 72 and the vacuum box 1 , and the sealing ring is used to seal the gap between the guide sleeve 72 and the vacuum box 1 , so that the vacuum box 1 has good sealing performance.

The connecting plate 73 is connected to the lower side of the guide shaft 71. The screw nut 74 is arranged on the connecting plate 73. The transmission screw 75 is threadedly matched with the screw nut 74. The driving member 76 is arranged on the outer side of the vacuum box 1, and the driving member 76 is configured to drive the transmission screw 75 to rotate around the Z direction. It can be understood that the guide shaft 71 is driven to move by the driving structure composed of the transmission screw 75 and the screw nut 74, which can make the movement accuracy of the bearing platform 6 higher and smoother. In this embodiment, the driving member 76 is a servo motor. The servo motor has the advantages of stable operation and long service life.

[0052] Furthermore, the driving mechanism 7 further includes a transmission assembly 77, which is disposed between the output shaft of the servo motor and the transmission screw 75 to transmit the torque output by the servo motor via the output shaft to the transmission screw 75. It can be understood that the arrangement of the transmission assembly 77 can make the arrangement position of the servo motor more flexible.

[0053] Specifically, the transmission assembly 77 includes a synchronous wheel 771, a driving wheel 772 and a synchronous belt 773. The synchronous wheel 771 is coaxially arranged on the transmission screw 75, the driving wheel 772 is coaxially arranged on the output shaft of the servo motor, and the synchronous belt 773 is wound around the synchronous wheel 771 and the driving wheel 772. It can be understood that the transmission of the synchronous belt 773 has the advantages of high transmission accuracy and not easy to slip. The transmission assembly 77 also includes a tensioning wheel 774 rotatably arranged on the outside of the vacuum box 1, and the synchronous belt 773 is wound around the synchronous wheel 771, the driving wheel 772 and the tensioning wheel 774. Such an arrangement can make the synchronous belt 773 run more smoothly. It should be noted that the tensioning wheel 774 is a prior art, and the specific structure of the tensioning wheel 774 can be selected according to the actual application scenario, and no specific requirements and restrictions are made on this.
