Description

Technical Field

[0001] The utility model relates to the technical field of touch screen glass detection, and particularly relates to a tray blanking assembly. Background Art

[0002] The AOI device is a high-precision and high-efficiency detection technology, which performs non-contact automatic inspection on printed circuit boards (PCBs) or other electronic components through light sources and cameras. The AOI device has the function of fully inspecting the appearance defects of touch screen glass (hereinafter referred to as glass). Before detection, the glass enters the AOI full-inspection device after being cut, edge-ground, cleaned and dried.

[0003] In the prior art, a lifting device is used to lift the tray containing glass to the AOI device, and a manipulator is used to suck up the glass and place it on the feeding conveyor belt of the AOI device. The feeding conveyor belt transports the glass into the detection port of the AOI device. However, when all the glass in the tray is picked up, it is necessary to manually remove the empty tray. This way of manually taking the tray is likely to cause bumps, resulting in the scrapping of the tray. Moreover, due to space limitations (such as the limitation of the robotic arm), it is not convenient for manual operation to take the tray. In addition, it is highly dependent on manpower, and the labor cost is high. Content of the Utility Model

[0004] The utility model aims to provide a tray blanking assembly to provide a device for replacing manual blanking of trays.

[0005] To solve the above problems, the utility model provides the following technical solution:

[0006] A tray blanking assembly includes a transverse movement module and a lifting module. The transverse movement module includes a frame and a conveyor belt arranged on the frame. The conveyor belt drives a transverse movement arm. The transverse movement arm is fixedly provided with a first cylinder. The movable end of the first cylinder is fixedly connected with a lifting plate. The lifting plate is provided with a plurality of adjustment grooves distributed along the circumferential direction. Each adjustment groove is fixedly connected with a vacuum suction cup opposite to the tray. The lifting module includes a bracket. The bracket is fixedly provided with a second cylinder. The second cylinder drives a support plate. The support plate is used to receive the tray.

[0007] Working Principle and Beneficial Effects of the Utility Model:

[0008] When this solution is used, the transverse moving arm, cylinder, lifting plate and multiple vacuum suction cups are moved to the top of the material tray through the conveyor belt. The cylinder works to make the lifting plate move toward the material tray. Multiple vacuum suction cups are distributed along the circumferential direction so that the multiple vacuum suction cups are sucked tightly on the material tray. Then the movable end of the cylinder returns to make the multiple vacuum suction cups pick up the material tray. The conveyor belt reverses the transmission to make the transverse moving arm, cylinder, lifting plate and multiple vacuum suction cups move and take the material tray away from the work station. At this time, the material tray moves to the top of the support plate. The multiple vacuum suction cups do not work and do not generate suction. The material tray detaches and falls onto the support plate. The cylinder drives the support plate to move downward to complete the unloading of the material tray.

[0009] This solution uses the coordination of multiple suction cups and conveyor belts to absorb the material tray and move it away from the workstation in a directed manner. The material tray is not easily bumped into, causing it to be scrapped, and is not restricted by space, thereby improving the efficiency of material tray transfer; the cylinder drives the pallet to move downward to complete the unloading of the material tray.

[0010] Optimally, the number of the vacuum suction cups is 4 and they are evenly spaced. The material tray can be stably sucked up by the 4 vacuum suction cups for transfer and unloading.

[0011] Optimally, the conveyor belt is specifically a belt conveyor belt. The belt conveyor belt has a smooth transmission process, which is conducive to the smooth transmission of the material tray to prevent the material tray from shaking during the transmission process.

[0012] Optimally, the axes of the plurality of adjustment slots face the central axis of the lifting plate. This optimization scheme can achieve the purpose of quickly adjusting the position of the vacuum suction cup.

[0013] Optimally, the adjustment groove is a strip-shaped groove.

[0014] Optimally, the support plate is fixedly provided with a tray limiting plate. When the tray is placed on the support plate, the tray limiting plate can limit the tray. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a further detailed description through specific embodiments:

[0021] The reference numerals in the accompanying drawings of the specification include: frame 1, conveyor belt 2, transverse moving arm 3, first cylinder 4, vacuum suction cup 5, lifting plate 6, tray 7, second cylinder 8, bracket 9, supporting plate 10, and tray limiting plate 11.

[0022] In the following statements, the orientation terms such as "left", "right", "up", and "down" are based on the orientation shown in the drawings. In practice, if the corresponding structures are changed in the same direction based on the orientation and the relative positions remain unchanged, it does not affect the implementation of the solution.

[0023] Embodiment: A tray unloading assembly, as Figure 5 shown, includes a transverse moving module and a lifting module. As Figure 1 shown, the transverse moving module includes a frame 1 and a conveyor belt 2 installed on the frame 1. The conveyor belt 2 is driven by a motor. The conveyor belt 2 is specifically a belt conveyor belt 2. A transverse moving arm 3 is fixedly connected to the belt of the conveyor belt 2. The transverse moving arm 3 is fixedly provided with a first cylinder 4. The movable end of the first cylinder 4 is fixedly connected to a lifting plate 6. Four adjusting grooves are distributed along the circumferential direction of the lifting plate 6. Each adjusting groove is fixedly connected to a vacuum suction cup 5 opposite to the tray 7. As Figure 4 shown, the lifting module includes a bracket 9. The bracket 9 is fixedly provided with a second cylinder 8. The second cylinder 8 drives a supporting plate 10. The supporting plate 10 is used to receive the tray 7.

[0024] When this solution is used, as Figure 2 shown, the transverse moving arm 3, the first cylinder 4, the lifting plate 6, and the four vacuum suction cups 5 are moved to directly above the tray 7 through the transmission of the conveyor belt 2. The first cylinder 4 works to make the lifting plate 6 move towards the tray 7. The four vacuum suction cups 5 are distributed along the circumferential direction, so that the four vacuum suction cups 5 are tightly adsorbed on the tray 7. Then the movable end of the cylinder returns, so that the four vacuum suction cups 5 adsorb the tray 7. The conveyor belt 2 reversely transmits to move the transverse moving arm 3, the first cylinder 4, the lifting plate 6, and the four vacuum suction cups 5, and takes the tray 7 away from the working station. As Figure 3 shown, at this time, the tray 7 moves to directly above the supporting plate 10. The four vacuum suction cups 5 do not work and do not generate suction. The tray 7 disengages and falls onto the supporting plate 10. The second cylinder 8 drives the supporting plate 10 to move downward to complete the unloading of the tray 7. The working principle of the vacuum suction cup 5 and how to generate suction belong to the conventional technologies in this field.

[0025] In this solution, through the cooperation of four vacuum suction cups 5 and the conveyor belt 2, the tray 7 is adsorbed and moved away from the work station in a directional manner. The tray 7 is not easily damaged by collision, resulting in the scrapping of the tray 7, and it is not restricted by space, improving the transfer efficiency of the tray 7; the pallet 10 catches the tray 7, and the second cylinder 8 drives the pallet 10 to move downward to complete the unloading of the tray 7.

[0026] Optimally, a tray limiting plate 11 is fixedly provided on the pallet. When the tray 7 is placed on the pallet 10, the tray limiting plate 11 can limit the tray 7.

[0027] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.
