[0028] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] This embodiment proposes a panel buffer conveying device, combined with Figures 1 to 11 As shown, it includes:

[0031] The product flows into the lifting and transfer unit 1, which is used to receive the panel products delivered by the uplink equipment and transport the panel products forward, to the left, or backward.

[0032] At least one buffer unit 2 is provided on the side of the inflow lifting and transfer unit 1. The buffer unit 2 is used to buffer the panel products delivered by the inflow lifting and transfer unit 1 or to send the buffered panel products back to the inflow lifting and transfer unit 1.

[0033] The lifting and transfer unit 4 is located between the front side of the inflow lifting and transfer unit 1 and the downstream device. The lifting and transfer unit 4 is used to position and scan the panel products delivered by the inflow lifting and transfer unit 1.

[0034] The manual feeding unit 5 is located on the side of the lifting and transfer unit 4. The manual feeding unit 5 is used to receive abnormal panel products identified by the lifting and transfer unit 4 or to transport panel products manually placed on it to the lifting and transfer unit 4.

[0035] In the above structure, the inflow lifting and transfer unit 1, the buffer unit 2, the lifting and transfer unit 4, and the manual feeding unit 5 form a buffer conveying system. When the panel products conveyed by the upstream equipment enter the inflow lifting and transfer unit 1, they can be processed according to the needs of the downstream equipment. If the downstream equipment needs panel products, the inflow lifting and transfer unit 1 will convey the panel products forward to the lifting and transfer unit 4, where the lifting and transfer unit 4 will perform positioning and barcode scanning before conveying them to the downstream equipment. If the downstream equipment does not need panel products during the process, the inflow lifting and transfer unit 1 will convey the panel products laterally to the buffer unit 2 for buffering. When the upstream equipment... When panel products cannot be supplied in time, the inflow lifting and transfer unit 1 can obtain panel products from the buffer unit 2, thereby ensuring that the downstream equipment receives panel products in a timely manner. Compared with the prior art, this utility model can realize flexible buffering and product transportation, and the upstream and downstream equipment does not need to stop and wait, resulting in higher transportation efficiency. At the same time, by setting the manual feeding unit 5, this utility model helps to manually inspect the abnormal panel products identified by the lifting and transfer unit 4, or facilitates the manual feeding of panel products to the lifting and transfer unit 4, thereby replenishing panel products for the downstream equipment in a timely manner. In addition, this utility model has many functions such as barcode scanning and correction, which not only has stronger automation performance, but also better meets the process requirements.

[0036] To improve the slow storage capacity, combined with Figure 1 , Figure 10 and Figure 11 As shown, this embodiment includes two buffer units 2, which are respectively located on the left and right sides of the inflow lifting and transfer unit 1.

[0037] Regarding the preferred structure of the buffer unit 2, the buffer unit 2 includes a buffer frame 20, on which a buffer conveying roller group 21, a multi-layer buffer bin 22, a buffer conveying drive mechanism 23, and a buffer bin lifting drive mechanism 24 are provided. The buffer conveying drive mechanism 23 is used to drive the buffer conveying roller group 21 to operate, and the buffer bin lifting drive mechanism 24 is used to drive the multi-layer buffer bin 22 to rise layer by layer, so that the panel products conveyed by the buffer conveying roller group 21 are carried on the corresponding shelves in the multi-layer buffer bin 22.

[0038] Furthermore, the buffer conveying roller group 21 includes a buffer conveying bracket 210, on which multiple parallel buffer conveying roller shafts 211 are provided. Multiple buffer conveying wheels 212 are evenly distributed on the buffer conveying roller shafts 211. A buffer drive roller shaft 213 is provided on the outer side of the buffer conveying bracket 210. The buffer drive roller shaft 213 is vertically disposed below the end of the buffer conveying roller shaft 211. The buffer drive roller shaft 213 and the end of the buffer conveying roller shaft 211 are connected by a magnetic wheel assembly 214. The buffer conveying drive mechanism 23 includes a buffer drive motor 215 for driving the buffer drive roller shaft 213 to rotate.

[0039] To make the buffer bin structure compact, in this embodiment, there is a gap 216 of a preset width between two adjacent buffer conveyor rollers 211. The multi-layer buffer bin 22 includes multiple front vertical bars 220 and multiple rear vertical bars 221. The front vertical bars 220 and the rear vertical bars 221 correspond one-to-one. Multiple shelf crossbars 222 with equal vertical spacing are fixed between the front vertical bars 220 and the rear vertical bars 221. The front vertical bars 220, the rear vertical bars 221 and the shelf crossbars 222 can pass through the gap 216. Multiple shelf crossbars 222 located on the same plane form a shelf.

[0040] As a preferred embodiment, the buffer bin lifting drive mechanism 24 includes a buffer lifting plate 240 and a buffer lifting motor 241. The buffer lifting plate 240 is fixedly connected to the multi-layer buffer bin 22, and the buffer lifting motor 241 is connected to the buffer lifting plate 240 via a lead screw assembly 242.

[0041] In the above structure, when receiving and sending panel products, the buffer conveyor roller group 21 is driven to rotate forward or backward by the buffer conveyor drive mechanism 23. During the buffering of panel products, the buffer bin lifting drive mechanism 24 drives the multi-layer buffer bin 22 to move upward layer by layer, so that the empty shelf moves to a position flush with the buffer conveyor roller group 21, so that the buffer conveyor roller group 21 can straightly convey the panel products onto the shelf. When the buffer unit 2 replenishes panel products to the inflow lifting and transfer unit 1, the buffer bin lifting drive mechanism 24 drives the multi-layer buffer bin 22 to move downward layer by layer. When the shelf falls to an appropriate height, the panel products are placed on multiple buffer conveyor rollers 212. Based on the above structural principle, it can be seen that this embodiment, based on the good cooperation between the buffer conveyor roller group 21 and the multi-layer buffer bin 22, can buffer a large number of panel products. At the same time, the structural layout is reasonable, making the buffer unit 2 compact and occupying little space.

[0042] For the preferred structure of the lifting and transferring unit 4, please refer to [link / reference]. Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 In this embodiment, the lifting and transfer unit 4 includes a lifting and transfer bracket 40, which is equipped with a reversing transfer roller group 41, a correction component 42, a blocking mechanism 43, and a VCR scanning component 44, wherein:

[0043] The reversing transfer roller group 41 is used to receive panel products conveyed by the inflow lifting transfer unit 1, to convey panel products to the downlink equipment, and to cooperate with the manual feeding unit 5 to convey panel products.

[0044] The blocking mechanism 43 is located at the front end of the reversing transfer roller group 41, and the blocking mechanism 43 is used to block the front end of the panel product.

[0045] The correction component 42 is positioned above the reversing transfer roller group 41, and the correction component 42 is used to push against the left and right ends of the panel product.

[0046] The VCR scanning component 44 is located above the reversing transfer roller group 41, and the VCR scanning component 44 is used to scan and identify the panel product.

[0047] Specifically, the reversing transfer roller assembly 41 includes a front and rear conveying roller assembly 410, a left and right conveying roller assembly 411, a front and rear conveying drive mechanism 412, and a left and right conveying drive mechanism 413. The front and rear conveying roller assembly 410 and the front and rear conveying drive mechanism 412 are both mounted on the lifting transfer bracket 40. The front and rear conveying roller assembly 410 is driven by the front and rear conveying drive mechanism 412 to rotate and convey the panel product forward. The lifting transfer bracket 40 is provided with a lifting fixing plate 400, which is equipped with a lifting motion frame 401 and a lifting cylinder 402 for driving the lifting motion frame 401 to move up and down. The left... The right conveyor roller group 411 is mounted on the lifting motion frame 401. The front and rear conveyor roller groups 410 are evenly distributed with multiple clearance gaps 414. The left and right conveyor roller groups 411 include multiple left and right conveyor rollers 415. The left and right conveyor rollers 415 can pass through the clearance gaps 414. When the lifting cylinder 402 lifts the lifting motion frame 401 upward, it drives the left and right conveyor rollers 415 to protrude above the front and rear conveyor roller groups 410. The left and right conveying drive mechanism 413 is used to drive the left and right conveyor roller groups 411 to operate, and the panel products are conveyed to the manual feeding unit 5 by the multiple left and right conveyor rollers 415.

[0048] In the above structure, the front and rear conveying roller groups 410 and the left and right conveying roller groups 411 are stacked vertically. The rollers in the front and rear conveying roller groups 410 and the left and right conveying roller groups 411 are staggered. The left and right conveying rollers 415 located below can pass through the clearance gaps 414 located above. Therefore, when panel products need to be conveyed from the front and rear, the lifting cylinder 402 drives the lifting motion frame 401 to fall downwards. The front and rear conveying roller groups 410 convey the panel products. When an abnormal product is found, the lifting and transfer unit 4 needs to transport the abnormal panel product to the manual feeding unit 5. At this time, the lifting cylinder 402 lifts the lifting motion frame 401 upwards, causing the left and right conveying rollers 415 to protrude above the front and rear conveying roller groups 410. At the same time, the left and right conveying drive mechanism 413 drives the left and right conveying roller groups 411 to operate, using multiple left and right conveying rollers 415 to transport the panel products to the manual feeding unit 5.

[0049] This embodiment preferably includes VCR scanning. Specifically, the VCR scanning component 44 includes a scanning forward and backward motion module 440, the moving end of the scanning forward and backward motion module 440 is provided with a scanning left and right motion module 441, and the moving end of the scanning left and right motion module 441 is provided with a VCR scanning camera 442.

[0050] As a preferred method, combined Figure 5 and Figure 6 As shown, the correction component 42 includes a left and right synchronous motion module 420. The left and right moving ends of the left and right synchronous motion module 420 are respectively provided with a left lifting cylinder 421 and a right lifting cylinder 422. The moving end of the left lifting cylinder 421 is provided with a left correction support rod 423. The bottom of the left correction support rod 423 is provided with a plurality of left correction stops 424. The moving end of the right lifting cylinder 422 is provided with a right correction support rod 425. The bottom of the right correction support rod 425 is provided with a plurality of right correction stops 426.

[0051] In the above structure, the left and right synchronous motion module 420 includes a linear motion module. The left and right synchronous motion module 420 can drive the left and right correction support rods to move closer to each other or farther apart, so that the left and right correction support rods drive the left and right correction stop rods 424 to push and correct the panel product. Not only is the correction efficiency high, but the corrected panel product can also be kept in the center position on the reversing transfer roller group 41.

[0052] As a preferred method, please refer to Figure 9 The blocking mechanism 43 includes a lifting blocking cylinder 430, the moving end of the lifting blocking cylinder 430 is provided with a lifting blocking frame 431, and the lifting blocking frame 431 is provided with a plurality of blocking rods 432.

[0053] In this embodiment, please refer to Figure 2 The manual feeding unit 5 includes a manual feeding frame 50, on which a manual feeding conveyor roller group 51 is provided, and a heightening foot pad frame 52 is provided adjacent to the manual feeding frame 50.

[0054] In a preferred embodiment of this utility model, the structure and principle of the manual feeding conveyor roller group 51 can be referred to the buffer conveyor roller group 21. The manual feeding conveyor roller group 51 and the buffer conveyor roller group 21 only need to have left and right conveying functions.

[0055] In a preferred embodiment of this utility model, the structure and principle of the inflow lifting and transfer unit 1 can be referred to the reversing transfer roller group 41. The inflow lifting and transfer unit 1 and the reversing transfer roller group 41 need to have the function of conveying panel products from front to back, and also need to have the function of lifting the panel products and conveying them from side to side.

[0056] Please see Figure 1 This embodiment includes an offset lifting and transfer unit 3, which is located in front of the inflow lifting and transfer unit 1, and a lifting and transfer unit 4 is located on the right side of the offset lifting and transfer unit 3.

[0057] In this embodiment, when the upward-moving product flows into the inflow lifting and transfer platform, the product can be lifted and transferred to the left or right into the buffer roller (or it can flow directly into the offset lifting and transfer unit). The buffer bin can be raised and lowered, and a single-sided bin can buffer 40 layers. When the upward-moving equipment does not produce in time, the product can flow out from the buffer bin and then flow into the offset lifting and transfer unit. The offset lifting and transfer platform will convey the product in the Y direction to the outflow lifting and transfer unit, and then the correction component will clamp it to center the product. Then the VCR will scan the code to read the information (the scan can cover the entire position of the product), and then the product will flow into the downward-moving equipment. When the code reading system determines that there is an abnormal product, it will be lifted and moved laterally to the manual station, where the abnormality will be judged and handled by the operator. In addition, the manual station can also put products in, and then the products will flow into the lifting and moving system and then into the downward-moving equipment.

[0058] It should be noted that this embodiment uses a scenario where the product outlets and inlets of the upstream and downstream devices are offset. Therefore, this embodiment can be called an offset panel buffer device. In practical applications, ordinary display panel production lines often lack offsetting or buffer stations, and these buffer stations have limited functionality, resulting in poor synchronization of upstream and downstream device efficiencies and impacting overall line production efficiency. Therefore, this embodiment provides a fully functional offset buffer device. Please refer to [link to relevant documentation]. Figure 1 The offset position relationship between the inflow lifting and transfer unit 1 and the lifting and transfer unit 4 described herein is applicable to scenarios where uplink and downlink equipment are offset.

[0059] Example 2

[0060] Please see Figure 12 The difference between this embodiment and embodiment one is that the lifting and transfer unit 4 is located in front of the inflow lifting and transfer unit 1.

[0061] It should be noted that in this embodiment, the product outflow and inflow of the uplink device and the downlink device are aligned, so this embodiment can be called a linear panel buffer device.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
