[0028] Example:

[0029] like Figure 1 As shown, the utility model discloses a transfer table for LENS transfer, including a conveyor line body 1, a material tray 2 and a lifting mechanism 3. The main components of the utility model are described in detail below:

[0030] like Figure 1 and Figure 2 As shown, two parallel conveyor belts 11 are provided on the conveyor line body 1 for transferring and conveying the material tray 2.

[0031] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the material tray 2 can be freely taken and placed on the conveyor belt 11. The upper end surface of the material tray 2 is provided with a plurality of placement grooves 21 for positioning and placing the cover material 4. The placement grooves 21 are provided with negative pressure suction holes 21a. The lower end surface of the material tray 2 is provided with docking holes 22. The docking holes 22 are connected to the negative pressure suction holes 21a. The vacuum device is connected through the docking holes 22 to evacuate the negative pressure suction holes 21a, so that the air pressure at the negative pressure suction holes 21a is reduced, and the cover material 4 is adsorbed and fixed in the placement grooves 21 by utilizing the air pressure difference.

[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the lifting mechanism 3 is arranged between the two conveyor belts 11. The lifting mechanism 3 is provided with a positioning sensor 31, a lifting plate 32 that can move up and down, and a negative pressure suction pipe 33. The negative pressure suction pipe 33 can be connected with the docking hole 22. The negative pressure suction pipe 33 is connected with the docking hole 22 to pump air and reduce the air pressure at the negative pressure suction hole 21a. The aperture of the negative pressure suction pipe 33 is larger than the aperture of the docking hole 22. When connected, the negative pressure suction pipe 33 is buckled on the outer periphery of the docking hole 22. When the position of the docking hole 22 has a slight deviation, it will not affect the connection between the negative pressure suction pipe 33 and the docking hole 22.

[0033] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the method and principle of use of the utility model are as follows: when in use, the material tray 2 containing the cover material 4 is transported to the conveyor belt 11, and the two parallel conveyor belts 11 are used to drive the material tray 2 to move along the conveying direction to maintain the stability of the material tray 2. When the material tray 2 is transported and is sensed by the positioning sensor 31, the conveyor belt 11 stops running, the lifting plate 32 rises to lift the material tray 2 to a certain height, and at the same time, the negative pressure suction pipe 33 rises and its end is buckled on the outer periphery of the docking hole 22, so that the negative pressure suction pipe 33 is aligned with the docking hole 22 and the negative pressure suction pipe 33. The hole 21a is connected, and a vacuum is drawn using the negative pressure suction pipe 33 to adsorb and fix the Cover material 4 in the placement groove 21 to prevent the Cover material 4 from shaking during processing. After the processing is completed, the negative pressure suction pipe 33 is away from the material tray 2, and the lifting plate 32 is lowered to place the material tray 2 back on the conveyor belt 11, and then the conveyor belt 11 moves to transport the material tray 2 to the next work section. During this process, the negative pressure suction pipe 33 is completely disconnected from the docking hole 22 and will not interfere with the movement of the material tray 2. The Cover material 4 does not need to be clamped in the material tray 2, and is easy to take and place.

[0034] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, in order to improve the working efficiency, the jacking mechanism 3 includes a jacking drive 34, the upper output end of the jacking drive 34 is connected to the jacking plate 32 and the negative pressure suction pipe 33, and the jacking drive 34 is one of a pneumatic cylinder, an electric cylinder and an oil cylinder, so that the jacking plate 32 and the negative pressure suction pipe 33 are controlled by the same drive to perform synchronous movement, thereby improving the processing efficiency.

[0035] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in order to improve the stability of the material tray during processing, pressure blocks 12 are provided at the corresponding positions of the jacking mechanism 3 on both sides of the conveyor line main body 1, and the pressure blocks 12 are located above the horizontal movement path of the material tray 2. During processing, the material tray 2 is pressed against the pressure blocks 12 by the jacking plate 32 to increase the stability of the material tray 2. At the same time, the contact surface pressure of the negative pressure suction pipe 33 when it is buckled on the outer periphery of the docking hole 22 is increased to avoid air leakage at the connection.

[0036] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in order to reduce the possibility of air leakage at the connection between the negative pressure suction pipe 33 and the material tray 2, an elastic sealing ring 33a is provided at the upper end of the negative pressure suction pipe 33. The elastic sealing ring 33a serves as a buffer to prevent the negative pressure suction pipe 33 from colliding with the material tray 2 and being damaged, while improving the sealing ability of the contact between the negative pressure suction pipe 33 and the material tray 2.

[0037] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in order to improve the processing accuracy, the jacking mechanism 3 also includes a guide plate 35, and a guide rod 36 is provided on the guide plate 35 which can slide up and down. The upper end of the guide rod 36 is connected to the jacking plate 32, so that the lifting and lowering of the jacking plate 32 is more stable, thereby improving the positioning and jacking accuracy, thereby improving the positioning and processing accuracy of the cover material 4.

[0038] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in order to facilitate the taking and placing of cover materials and the switching of models, the material tray 2 includes a detachable upper cover plate 2a and a lower cover plate 2b. The upper cover plate 2a and the lower cover plate 2b enclose a negative pressure air cavity. The negative pressure suction hole 21a is provided on the upper cover plate 2a and is connected to the negative pressure air cavity. The docking hole 22 is provided on the lower cover plate 2b and is connected to the negative pressure air cavity. When taking and placing materials, it is sufficient to directly replace the upper cover plate 2a.

[0039] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, in order to improve processing efficiency, the conveyor belt 11 is driven by a servo motor 13, which improves the stability of conveying the Cover material 4, reduces the positioning adjustment time, and thus improves the conveying efficiency.

[0040] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
