[0039] In this embodiment, the driving assembly 8 includes a first motor 801 slidably mounted on the housing 1, a first screw 802 is connected to the output shaft of the first motor 801, a first guide rail 803 is fixedly provided on the first motor 801, a first slider 804 is slidably mounted in the first guide rail 803, the first screw 802 and the first slider 804 are threadedly connected, a second guide rail 805 is fixedly connected to the bottom of the first slider 804, a second slider 806 is slidably mounted in the second guide rail 805, a second screw 807 is threadedly mounted in the second slider 806, and the second screw 807 is threadedly mounted in the second slider 806. The rod 807 and the second guide rail 805 are rotatably connected. A second motor 808 is fixedly arranged on the second guide rail 805. A synchronous wheel 809 is fixedly connected to the output shaft of the second motor 808. A synchronous belt 810 is installed between the synchronous wheel 809 and the second screw 807. The first motor 801 drives the first screw 802 to rotate, thereby driving the first slider 804 and the second guide rail 805 to move left and right. The second motor 808 drives the second screw 807 to rotate, thereby driving the second slider 806 to move forward and backward, so that the device can change the dispensing position.

The first guide rail 803 forms a lifting structure with the third guide rod 25 through the second guide rod 21, the traction steel rope 22, the guide rod 23 and the fixing ring 24. Through the lifting structure on the device, when the second guide rod 21 moves upward, the bottom of the traction steel rope 22 will rise and cause the first guide rail 803 to move downward, so that the dispensing work can be carried out while the wafer is lifted later.

[0041] In this embodiment, the second slider 806 and the adjustment block 17 are fixedly connected. The adjustment block 17 forms a first sliding structure with the second guide rail 805 through the second slider 806 and the second screw 807. The second guide rail 805 forms a second sliding structure with the first guide rail 803 through the first slider 804 and the first screw 802.

When the bottom surface of the upper half of the conveyor belt 906 is pushed upward, the roller 905 is compressed so that the bracket 901 slides on the connecting shell 2 and the first spring 904 on the convex plate 903 is stretched. The first spring 904 facilitates the subsequent resetting of the stretched conveyor belt 906, so that the device can lift or transport the wafer as a whole or transport it horizontally without affecting the normal use of the conveyor belt 906.

The second support plates 12 on the left and right sides of the first support plate 11 are slidably connected to the connecting shell 2. After the slidably installed second support plate 12 moves to the top, the first support plate 11 can still continue to slide, so that the wafer can be subsequently transported to a suitable position for glue dispensing. The first guide rod 20 ensures that the second support plate 12 moves vertically up and down.

[0044] In this embodiment, a first connecting block 13 is fixedly provided on the first supporting plate 11, a second connecting block 14 is fixedly connected to the first connecting block 13, a third connecting block 16 is fixedly connected to the second supporting plate 12, a second spring 15 is fixedly connected between the third connecting block 16 and the second connecting block 14, a height of the first connecting block 13 is greater than a thickness of the first supporting plate 11, and the thicknesses of the first supporting plate 11 and the second supporting plate 12 are the same, ensuring that after the second supporting plate 12 moves to the top, the first supporting plate 11 can still move upward so as to transport the wafer to a suitable position, and the second spring 15 can reset the first supporting plate 11 and the second supporting plate 12 to Figure 6 status in .

[0045] It should be noted that the present invention is a fully automatic online wafer dispensing machine. First, Figure 4-Figure 6 , pictures and Fig.10As shown, when the device is in use, the wafer is placed on the conveyor belt 906 on one side of the connecting shell 2, and the wafer is supported by the protrusion 907 on the conveyor belt 906, so that the back of the wafer is in contact with the support structure as little as possible. When conveying the wafer, the third motor 902 on the conveying assembly 9 drives the roller 905 to rotate, and the roller 905 drives the conveyor belt 906 to rotate. After conveying to the bottom of the top opening of the connecting shell 2, the first electric push rod 10 is extended, and the first support plate 11 is driven to move upward through the first connecting block 13. The first support plate 11 pushes the wafer upward, and after the second support plate 12 moves to the top, the first support plate 1 1 can still move upward, at this time, the second connecting block 14 on the first connecting block 13 slides on the third connecting block 16, and the second spring 15 is compressed, so that the wafer is transported to a suitable position. In the process of the second supporting plate 12 moving upward, the first guide rod 20 and move upward, the second guide rod 21 moves upward and makes the bottom of the traction steel rope 22 move upward. When the bottom of the traction steel rope 22 moves upward, under the guidance of the guide rod 23, the first guide rail 803 will move downward, so that the glue dispenser body 19 moves downward, so that the device can automatically move the glue dispenser body 19 downward while lifting the wafer, so as to perform the subsequent glue dispensing work. When the bottom surface of the upper part of the conveyor belt 906 is pushed upward, the roller 905 is compressed so that the bracket 901 slides on the connecting shell 2 and the first spring 904 on the convex plate 903 is stretched. The first spring 904 facilitates the subsequent resetting of the stretched conveyor belt 906, so that the device can lift or transport the entire wafer horizontally without affecting the normal use of the conveyor belt 906.

[0046] like Figure 1-Figure 3 , Fig. 9 and Fig.10 As shown, when the device is dispensing glue, the first motor 801 drives the first screw 802 to rotate, the first screw 802 drives the first slider 804 and the second guide rail 805 to move left and right, the second motor 808 drives the second screw 807 to rotate, and the second screw 807 drives the second slider 806 to move forward and backward, so that the device can change the left and right position and the front and back position of the adjustment block 17, and then the initial height of the glue dispenser body 19 can be adjusted by the second electric push rod 18 to perform the glue dispensing work. When dispensing glue, the cover plate 4 is closed. After the cover plate 4 is closed, the conductive plate 503 on the electric heating tube 6 will contact the conductive contact 505 on the power supply 504, so that the electric heating tube 6 is automatically energized for heating, so that the device will not cool down quickly after the glue dispensing is completed.
