Description

Technical Field

[0001] The utility model relates to the technical field of automatic production and processing equipment, in particular to a material tray internal circulation buffer machine. Background Art

[0002] In the production and processing process of electronic circuits, in order to improve the processing efficiency, automatic processing equipment is generally used for corresponding processing work. During the processing, trays are needed to carry products or materials, so as to transport multiple groups of product materials, facilitating the pick-and-place manipulator to transfer the product materials to the corresponding processing stations for corresponding processing procedures. When processing products such as glass panels, since the temperature of the products is relatively high in the front-end processes, it is necessary to wait for the products to cool down before sending them to the next process for processing. Therefore, generally, the products need to be sent to a buffer device for buffering and cooling, and after the temperature of the glass panel drops to an appropriate range value, it is sent out for processing in the next process. Most of the existing buffer devices adopt a flat storage method, that is, multiple glass panels are placed flat for buffering. This method occupies a large area and has a high storage risk, easily causing the glass panels to be soiled or damaged. At the same time, due to the low degree of automation, this flat placement method is not conducive to manual picking and placing of glass panels, especially it is difficult to pick and place the glass panels near the inside, reducing the reliability and convenience during the production process.

[0003] Therefore, there are defects in the prior art and improvement is needed. Summary of the Utility Model

[0021] The following will combine the accompanying drawings and specific embodiments to describe the present invention in detail.

[0022] Please refer to Figures 1 to 3 , the present invention provides a tray internal circulation buffer machine, including: a lower frame 1, a lower pallet transfer mechanism 2 disposed at the bottom inside the lower frame 1, a sunken pallet bin 3 disposed above one end of the lower pallet transfer mechanism 2, and a rising pallet bin 4 disposed above the other end of the lower pallet transfer mechanism 2. The lower pallet transfer mechanism 2 moves back and forth below the sunken pallet bin 3 and the rising pallet bin 4. During operation, by moving the tray loaded with the glass panel to the top of the sunken pallet bin 3 and stacking it in the sunken pallet bin 3. When the number of trays in the sunken pallet bin 3 accumulates to the set quantity, the lower pallet transfer mechanism 2 takes away the lowermost tray from the bottom of the sunken pallet bin 3, moves the tray to below the rising pallet bin 4, and pushes the picked-up tray into the top of the rising pallet bin 4, thereby pushing up the stacked trays in the rising pallet bin 4, facilitating the removal of the uppermost tray in the rising pallet bin 4 for feeding. By stacking the trays loaded with the glass panel in the sunken pallet bin 3 and gradually sinking in the sunken pallet bin 3 during the feeding process, and then moving the lowermost tray in the sunken pallet bin 3 to the rising pallet bin 4 by the lower pallet transfer mechanism 22 and gradually rising in the rising pallet bin 4 during the feeding process, the trays are cached inside the lower frame 1 without stopping the feeding and supplying, extending the feeding duration of a single tray, thereby providing a cache for the trays in the lower frame 1, enabling the glass panel in the tray to have sufficient time to cool down and meeting the processing requirements of the next process.

[0023] In some alternative embodiments, please refer to Figure 2, the lower tray moving mechanism 2 includes: a lower tray driving motor 21 disposed at the bottom of the lower frame 1, a lower tray transmission mechanism 22 connected to the output end of the lower tray driving motor 21, a sliding bracket 23 connected to the lower tray transmission mechanism 22, a top tray lifting mechanism 24 disposed on the sliding bracket 23, and a lifting plate 25 disposed at the output end of the top tray lifting mechanism 24. The lower tray driving motor 21 drives the sliding bracket 23 to move reciprocally through the lower tray transmission mechanism 22, and the top tray lifting mechanism 24 drives the lifting plate 25 to move up and down reciprocally. When the lower tray driving motor 21 moves the lifting plate 25 below the sunken tray bin 3, the top tray lifting mechanism 24 raises the lifting plate 25, so that the lifting plate 25 contacts the tray at the bottom of the sunken tray bin 3. The sunken tray bin 3 releases the lowermost tray, and at the same time the top tray lifting mechanism 24 lowers the lifting plate 25, so that the tray is completely separated from the sunken tray bin 3. Then the lower tray driving motor 21 is started to move the lifting plate 25 below the ascending tray bin 4, and then the top tray lifting mechanism 24 is started to raise the lifting plate 25, so that the tray on the lifting plate 25 pushes the tray at the bottom of the ascending tray bin 4 to move upward, thereby sending the tray on the lifting plate 25 into the lowermost layer in the ascending tray bin 4.

[0024] In some alternative embodiments, the lower tray transmission mechanism 22 adopts a belt pulley transmission mechanism. The driving belt pulley of the belt pulley transmission mechanism is driven to rotate by the lower tray driving motor 21, thereby driving the belt to move. By connecting the sliding bracket 23 to the belt, the sliding bracket 23 is driven to move reciprocally through the movement of the belt.

[0025] In some alternative embodiments, the lower tray transmission mechanism 22 adopts a lead screw slider transmission mechanism. The lead screw is driven to rotate by the lower tray driving motor 21, thereby driving the lead screw slider to move along the direction of the lead screw through the lead screw.

[0026] In some alternative embodiments, the top tray lifting mechanism 24 adopts an electric push rod or a cylinder. The force of pushing and pulling is generated by the electric push rod or the cylinder, thereby realizing the driving of the up and down movement of the lifting plate 25.

[0027] In some alternative embodiments, a plurality of limiting claws 251 are respectively disposed around the lifting plate 25. By providing the limiting claws 251, the limiting and protection are provided for the periphery of the tray, avoiding the situation that the tray falls off the lifting plate 25 during the process of driving the lifting plate 25 to move by the lower tray driving mechanism, resulting in damage to the tray or the glass panel in the tray, and effectively ensuring the safety during the transportation process.

[0028] In some alternative embodiments, a tray picking sensor 252 is provided on the lifting plate 25 to facilitate detecting whether there is a tray on the lifting plate 25, thereby determining the working state of the current lifting plate 25 and moving to the corresponding working station for tray sinking or tray lifting operations.

[0029] In some alternative embodiments, referring to Figure 3 , the tray sinking bin 3 includes: a tray sinking mechanism bottom plate 31 provided on both sides of the lower frame 1, tray sinking fork plate cylinders 32 respectively provided on the tray sinking mechanism bottom plates 31 on both sides, a fork plate fixing plate 5 provided at the output end of the tray sinking fork plate cylinder 32, and a bin guiding rod 33 provided beside the fork plate fixing plate 5. The bin guiding rod 33 is close to the side surface of the tray stored in the tray sinking bin 3. When the top tray lifting mechanism 24 raises the lifting plate 25 so that the lifting plate 25 contacts the lowermost tray stacked in the tray sinking bin 3, the tray sinking fork plate cylinder 32 retracts, causing the fork plate fixing plate 5 to separate from the side wall of the tray, releasing the lowermost tray so that the tray falls onto the lifting plate 25. Then the top tray lifting mechanism 24 resets, causing the lifting plate 25 to move downward. At the same time, the stacked trays move downward synchronously, and the tray sinking fork plate cylinder 32 is activated to embed the fork plate fixing plate 5 into the side wall of the second-lowermost tray to fix and limit the stacked trays, facilitating the lower tray transfer driving motor 21 to move the lifting plate 25 below the tray lifting bin 4.

[0030] In some alternative embodiments, referring to Figure 3 , the tray lifting bin 4 includes: a tray lifting mechanism bottom plate 41 provided on both sides of the lower frame 1, tray lifting fork plate cylinders 42 respectively provided on the tray lifting mechanism bottom plates 41 on both sides, a fork plate fixing plate 5 provided at the output end of the tray lifting fork plate cylinder 42, and a bin guiding rod 33 provided beside the fork plate fixing plate 5. The bin guiding rod 33 is close to the side surface of the tray stored in the tray lifting bin 4. When the lifting plate 25 with a picked tray moves below the tray lifting bin 4 under the drive of the lower tray transfer driving motor 21 and the top tray lifting mechanism 24 simultaneously jacks up the tray, the tray lifting fork plate cylinder 42 retracts, causing the fork plate fixing plate 5 to be withdrawn from the side wall of the tray, so that the stacked trays fall onto the tray on the lifting plate 25. Under the drive of the top tray lifting mechanism 24, the tray on the lifting plate 25 is moved to the corresponding position of the fork plate fixing plate 5, and the tray lifting fork plate cylinder 42 is activated. Thus, the fork plate fixing plate 5 is pushed out by the tray lifting fork plate cylinder 42, and the fork plate fixing plate 5 is embedded into the side wall of the tray on the lifting plate 25 to fix the tray. Subsequently, the lifting plate 25 resets and waits for the next set of tray sinking or tray lifting operations.

[0031] In some alternative embodiments, a guide plate 51 is provided on the fork plate fixing plate 5. The guide plate 51 is close to the side surface of the stored tray. The top of the guide plate 51 inclines outward to form an inclined surface. The guide plate 51 can assist the bin guide rod 33 to align the whole plate, so that the trays can be in a stable stacked state during the processes of sinking and lifting the trays, meeting the requirement of stacking the trays.

[0032] In some alternative embodiments, referring to Figure 1 , an opening 11 is provided at the top of the lower frame 1. An upper tray handling mechanism 6 is arranged at the opening 11. An inlet conveying platform 7 and a blanking robotic arm 8 are respectively arranged at two ends of the upper tray handling mechanism 6. The tray containing the glass panel is moved into place by the inlet conveying platform 7. Then, the upper tray handling mechanism 6 removes the tray transported on the inlet conveying platform 7, and places the tray on the sinking bin 3 for stacking. When a tray in the lifting bin 4 is lifted, the upper tray handling mechanism 6 clamps and fixes the lifted tray in the lifting bin 4, and moves the tray to the blanking robotic arm 8. The blanking robotic arm 8 takes away the tray for discharging.

[0033] In some alternative embodiments, referring to Figure 4 , the upper tray handling mechanism 6 includes: an upper tray driving motor 61 arranged at the edge of the opening 11 of the lower frame 1, an upper tray transmission mechanism 62 connected to the output end of the upper tray driving motor 61, an upper tray movable bracket 63 connected to the output end of the upper tray transmission mechanism 62, a lifting cylinder 64 arranged on the upper tray movable bracket 63, a clamping cylinder 65 connected to the output end of the lifting cylinder 64, and a chuck block 66 arranged at the output end of the clamping cylinder 65. Two groups of upper tray movable brackets 63 are provided, and are respectively arranged at the two side edges of the opening 11.

[0034] When the inlet conveying platform 7 moves the tray containing the glass panel into place, the upper tray driving motor 61 drives the upper tray movable bracket 63 to move to the corresponding position of the inlet conveying platform 7 through the upper tray transmission mechanism 62. Then, the lifting cylinder 64 is started to move the chuck block 66 upward, so that the chuck block 66 is located at the corresponding height position of the tray on the inlet conveying platform 7. The clamping cylinder 65 is started to push out the chuck block 66, so as to clamp and fix both sides of the tray. Then, the upper tray driving motor 61 moves the tray above the sinking bin 3, and drives the lifting cylinder 64 to retract, so that the tray falls on the top of the trays stacked in the sinking bin 3. At the same time, the clamping cylinder 65 retracts to release the tray.

[0035] When a tray in the lifting tray bin 4 is lifted, the upper tray driving motor 61 drives the tray moving support bracket to move to the corresponding position of the lifting tray bin 4 through the upper tray transmission mechanism 62, starts the clamping cylinder 65, and pushes out the chuck block 66, so as to clamp and fix both sides of the tray. Then, the tray is lifted by the lifting cylinder 64, and at the same time, the tray is moved to the discharging robotic arm 8 by the upper tray driving motor 61, and the tray is placed at the discharging robotic arm 8, thereby discharging the tray.

[0036] In some embodiments, the upper tray transmission mechanism 62 adopts a belt pulley transmission mechanism, and the driving wheels of the belt pulley transmission mechanisms on both sides are connected by a rotating shaft, so as to perform synchronous transmission, ensure that the belt pulley transmission mechanisms on both sides can move synchronously, and meet the requirement of moving the tray.

[0037] In some alternative embodiments, please refer to Figure 5 , an upper frame 9 is arranged on the lower frame 1, and a human-machine interface 91 is arranged on the upper frame 9. By arranging the upper frame 9 covering the lower frame 1, the mechanisms on the lower frame 1 are protected, and it is avoided that dust, impurities, etc. fall on the trays in the lower frame 1 and contaminate the glass panel. At the same time, various working parameters of the equipment are set through the human-machine interface 91, and the working state can be controlled to meet the requirements of control and state viewing.

[0038] In summary, in the present utility model, the trays containing glass panels are stacked in the sunken tray bin 3, and gradually sink in the sunken tray bin 3 during the feeding process. Subsequently, the lower tray mechanism 2 moves the tray at the bottom of the sunken tray bin 3 to the lifting tray bin 4, and gradually rises in the lifting tray bin 4 during the feeding process. In this way, without stopping the feeding and supplying, the trays are cached inside the lower frame 1, the feeding duration of a single tray is extended, so as to provide caching for the trays in the lower frame 1, enabling the glass panels in the trays to have sufficient time to cool down and meet the processing requirements of the next process.

[0039] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
