Description

Technical Field

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

[0002] The AOI device is a high-precision and high-efficiency detection technology, which performs non-contact automated 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, edged, cleaned, and dried.

[0003] In the prior art, a lifting device is used to lift multiple trays 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 taking the tray is likely to cause bumps, resulting in the scrapping of the tray. Moreover, due to space limitations (such as the limitations of the robotic arm), it is not convenient for manual removal of the tray. In addition, it is highly dependent on manpower, and the labor cost is relatively high. Summary of the Utility Model

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

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

[0006] A tray transfer assembly includes a transverse movement module. The transverse movement module includes a frame and a conveyor belt installed on the frame. The conveyor belt drives a transverse movement arm, and the transverse movement arm is slidably connected to the frame. The sliding direction of the transverse movement arm is the same as the conveying direction of the conveyor belt. The transverse movement arm is fixedly provided with a cylinder, and the cylinder drives a lifting plate. The lifting plate is provided with a plurality of adjustment slots distributed along the circumferential direction. Each adjustment slot is provided with a movable vacuum suction cup. The lifting plate is provided with a plurality of threaded holes at each adjustment slot. The vacuum suction cup is connected to one or more of the threaded holes through a screw rod.

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

[0008] When this solution is used, it is transmitted through a conveyor belt. The transverse moving arm, cylinder, lifting plate and multiple vacuum suction cups are moved directly above the tray. The movable end of the cylinder is perpendicular to the transverse moving arm, so that the movable end of the cylinder can generate the maximum displacement to make the lifting plate move towards the tray. The multiple vacuum suction cups are arranged along the circumferential direction, so that the multiple vacuum suction cups are tightly adsorbed on the tray. Then, the movable end of the cylinder returns, so that the multiple vacuum suction cups adsorb the tray and lift it up. The conveyor belt transmits in the reverse direction, so that the transverse moving arm, cylinder, lifting plate and multiple vacuum suction cups move, and the tray is taken away from the working station. Moreover, the vacuum suction cups are connected through screws and threaded holes, that is, the positions of the vacuum suction cups can be adjusted according to the size of the tray, so as to be applicable to adsorbing trays of different specifications and sizes, and improve the versatility.

[0009] Through the cooperation of multiple vacuum suction cups and the conveyor belt, this solution adsorbs the tray and takes it away from the working station. The tray is not easy to cause bumps, resulting in the scrapping of the tray, and is not restricted by space, improving the tray transfer efficiency.

[0010] Optimally, the number of the vacuum suction cups is 4, and they are evenly spaced. The tray can be stably adsorbed and transferred and unloaded by 4 vacuum suction cups.

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

[0012] Optimally, the axes of the multiple adjustment grooves face the central axis of the lifting plate. This optimized solution can achieve the purpose of quickly adjusting the positions of the vacuum suction cups.

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

[0018] The following is further detailed through specific embodiments:

[0019] The reference numerals in the attached drawings of the specification include: frame 1, conveyor belt 2, transverse moving arm 3, cylinder 4, vacuum suction cup 5, lifting plate 6, tray 7, threaded hole 8, screw 9.

[0020] In the following statements, orientation terms such as "left", "right", "up", and "down" are based on the orientation shown in the figure. In practice, when the corresponding structures change in the same direction based on the orientation and the relative positions remain unchanged, it does not affect the implementation of the solution.

[0021] Embodiment: A tray transfer assembly, as Figure 1 and Figure 2 shown, includes a transverse movement module. The transverse module includes a frame 1 and a conveyor belt 2 installed on the frame 1. The conveyor belt 2 is specifically a belt conveyor belt 2, and the belt conveyor belt 2 is driven by a motor. A transverse movement arm 3 is fixedly connected to the belt of the belt conveyor belt 2. The transverse movement arm 3 is slidably connected to the frame 1, and the sliding direction of the transverse movement arm 3 is the same as the transmission direction of the conveyor belt 2. A cylinder 4 is fixedly provided on the transverse movement arm 3. The movable end of the cylinder 4 is perpendicular to the transverse movement arm 3, and the movable end of the cylinder 4 is fixedly connected to a lifting plate 6. Four adjustment slots are provided on the lifting plate 6 along the circumferential direction. Four threaded holes 8 are provided on the lifting plate 6 at each adjustment slot. A vacuum suction cup 5 is connected to two of the threaded holes 8 through a screw 9.

[0022] As Figure 3 shown, when this solution is used, it is transmitted through the conveyor belt 2 to move the transverse movement arm 3, the cylinder 4, the lifting plate 6, and the four vacuum suction cups 5 to directly above the tray 7. The movable end of the cylinder 4 is perpendicular to the transverse movement arm 3, so that the movable end of the cylinder 4 can generate the maximum displacement to move the lifting plate 6 towards the tray 7. The four vacuum suction cups 5 are arranged 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 4 returns to make the four vacuum suction cups 5 adsorb and lift the tray 7. The conveyor belt 2 is reversely transmitted to move the transverse movement arm 3, the cylinder 4, the lifting plate 6, and the four vacuum suction cups 5, and take the tray 7 away from the working station. The vacuum suction cup 5 uses a vacuum pump (not shown in the figure) to provide negative pressure. How the vacuum pump provides negative pressure to the vacuum suction cup 5 to generate suction for adsorption belongs to the common technology in this field and will not be elaborated here.

[0023] And, as Figure 4 shown, the position of the vacuum suction cup 5 can be adjusted according to the size of the tray 7, so as to be applicable to adsorbing trays 7 of different specifications and sizes, thereby improving versatility.

[0024] 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 records 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 machines, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.
