Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of touch screen glass detection, in particular to a tray transfer assembly with a wire harness protection function. 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, edged, cleaned and dried.
[0003] In the prior art, a lifting device is used to lift the tray containing the 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 method of manually taking the tray is likely to cause bumps, resulting in the scrapping of the tray. In addition, due to space limitations (such as the limitations of the robotic arm), it is not convenient for manual operation to take the tray. Moreover, it is highly dependent on manpower, resulting in high labor costs.
[0004] Therefore, the applicant provides a tray transfer assembly, as Figure 1 shown, including 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. The transverse movement arm is fixedly provided with a cylinder, and the movable end is fixedly connected with a lifting plate. The lifting plate is fixedly connected with a vacuum suction cup opposite to the tray. The tray is adsorbed by the vacuum suction cup and taken away from the working station. However, in the prior art, the wire harness connected to the cylinder and the wire harness of the vacuum suction cup are not hidden and restricted. The wire harness supplies power to the cylinder and provides negative pressure to the vacuum suction cup. The operation space of the entire AOI device is narrow, and the wire harness moves randomly when the transverse movement arm moves, resulting in easy entanglement and wear of the wire harness, thereby affecting the operation of the vacuum suction cup and the cylinder. Summary of the Utility Model
[0005] The utility model aims to provide a tray transfer assembly with a wire harness protection function to solve the problem that the wire harness is easily entangled and worn during the movement of the transverse movement arm in the prior art.
[0006] To solve the above problems, the utility model provides the following technical solutions:
[0007] A tray transfer component with a wire harness protection function, comprising a frame and a conveyor belt mounted on the frame. The conveyor belt drives a transverse arm, and a cylinder is fixedly arranged on the transverse arm. The movable end of the cylinder is fixedly connected with a lifting plate, and a vacuum suction cup is fixedly arranged on the lifting plate. Both the cylinder and the vacuum suction cup are connected with wire harnesses. A chain is fixedly arranged between the frame and the transverse arm. The chain comprises a plurality of chain links that are movably connected to each other, and the wire harness passes through the plurality of chain links.
[0008] Working principle and beneficial effects of the present utility model:
[0009] When this solution is used, the transverse arm, the cylinder, the lifting plate and the vacuum suction cup are moved to directly above the tray through the transmission of the conveyor belt. The cylinder works to make the lifting plate move towards the tray, so that the vacuum suction cup tightly adheres to the tray. Then, the movable end of the cylinder returns to make the vacuum suction cup adsorb the tray, and the reverse transmission of the conveyor belt makes the transverse arm, the cylinder, the lifting plate and the vacuum suction cup move, taking the tray away from the working station.
[0010] Moreover, since the wire harness passes through a plurality of chain links, and the chain comprises a plurality of chain links that are movably connected to each other, and the chain is fixedly arranged between the frame and the transverse arm, the movement of the transverse arm drives the chain to bend, and the bending of the chain drives the wire harness to bend. During this process, the wire harness is always located inside the chain, so that there will be no problem of the wire harness moving randomly and getting tangled up.
[0011] Optimally, one end of the chain is fixedly connected to the frame, and the other end of the chain is bent into an arc and fixedly connected to the transverse arm. On the one hand, this optimization scheme is beneficial to the bending of the chain during movement. On the other hand, it is convenient for the wire harness to be connected to the cylinder or the vacuum suction cup after passing through the chain.
[0012] Optimally, the axis of the chain is parallel to the axis of the transverse arm. The chain can better cooperate with the movement of the transverse arm during movement.
[0013] Optimally, the chain link is fixedly provided with a baffle. The baffle is used to prevent the wire harness from detaching from the chain link.
[0014] Optimally, the part of the wire harness after passing through the chain is fixedly connected to the transverse arm. Description of the drawings

[0017] Figure 3 It is a schematic internal structure diagram of the chain;
[0018] Figure 4 Schematic diagram of the transmission method for driving the transverse moving arm by a conveyor belt Detailed implementation manners
[0019] The following is a further detailed description through specific implementation manners:
[0020] The reference signs in the attached drawings of the specification include: frame 1, conveyor belt 2, transverse moving arm 3, wire harness 4, lifting plate 5, vacuum suction cup 6, cylinder 7, tray 8, chain 9, baffle 10, chain link 11.
[0021] In the following statements, orientation words such as "left", "right", "up", and "down" are based on the orientation shown in the drawings. In practice, if 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.
[0022] Referring to Figure 1 , the tray transfer assembly in the prior art 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. A transverse moving arm 3 is fixedly connected to the belt of the conveyor belt 2. A cylinder 7 is fixedly provided on the transverse moving arm 3. The movable end of the cylinder 7 is fixedly connected to a lifting plate 5. A vacuum suction cup 6 is fixedly provided on the lifting plate 5. The wire harness 4 in the prior art is messy. During the movement of the transverse moving arm 3, the wire harness 4 is driven to move without direction, resulting in easy winding and wear of the wire harness 4, and further affecting the operation of the vacuum suction cup 6 and the cylinder 7.
[0023] Embodiment: A tray transfer assembly with a wire harness protection function, as Figure 2 , Figure 4 shown, 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. A transverse moving arm 3 is fixedly connected to the belt of the conveyor belt 2. A cylinder 7 is fixedly provided on the transverse moving arm 3. The movable end of the cylinder 7 is fixedly connected to a lifting plate 5. A vacuum suction cup 6 is fixedly provided on the lifting plate 5; A chain 9 is fixedly provided between the frame 1 and the transverse moving arm 3. The chain 9 includes a plurality of chain links 11 that are movably connected to each other. The wire harness 4 passes through the plurality of chain links 11 and is fixedly connected to the cylinder 7 (vacuum suction cup 6). A baffle 10 is fixedly provided on each chain link 11.
[0024] When this solution is used, as Figure 4 shown, the transverse moving arm 3, the cylinder 7, the lifting plate 5, and the vacuum suction cup 6 are moved to directly above the tray 8 through the transmission of the conveyor belt 2. The cylinder 7 works to make the lifting plate 5 move towards the tray 8, so that the vacuum suction cup 6 tightly adheres to the tray 8. Then, the movable end of the cylinder 7 returns to make the vacuum suction cup 6 adsorb the tray 8. The reverse transmission of the conveyor belt 2 makes the transverse moving arm 3, the cylinder 7, the lifting plate 5, and the vacuum suction cup 6 move, and takes the tray 8 away from the working station.
[0025] As Figure 3As shown, since the wire harness 4 passes through a plurality of chain links 11, and the chain 9 includes a plurality of chain links 11 that are movably connected to each other, that is, the chain links 11 are connected by pin shafts and can rotate relative to each other. The chain 9 is fixedly arranged between the frame 1 and the traversing arm 3. Therefore, when the traversing arm 3 moves, it drives the chain 9 to bend. When the chain 9 bends, it drives the wire harness 4 to bend. During the movement of the traversing arm 3, the wire harness 4 is always located inside the chain 9, and the baffle 10 is used to prevent the wire harness 4 from detaching from the chain link 11, so that the problem of the wire harness 4 moving randomly and becoming entangled will not occur.
[0026] 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 machines, 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.
