[0028] The present invention is described in more detail below with reference to the accompanying drawings and embodiments.

[0029] Embodiment 1

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

[0031] Flowing into the lifting and transferring unit 1, it is used to receive the panel products transported by the upstream equipment and transport the panel products forward, left or backward;

[0032] At least one buffer unit 2 is provided at the side of the inflow lifting and transferring unit 1, and the buffer unit 2 is used to buffer the panel products transferred from the inflow lifting and transferring unit 1 or to transfer the buffered panel products back to the inflow lifting and transferring unit 1;

[0033] The lifting and transferring unit 4 is arranged between the front side of the inflow lifting and transferring unit 1 and the downstream equipment, and the lifting and transferring unit 4 is used to locate and scan the panel products transferred from the inflow lifting and transferring unit 1;

[0034] The manual feeding unit 5 is arranged at the side of the lifting and transferring unit 4 , and is used to receive the panel products identified as abnormal by the lifting and transferring unit 4 or to transport the panel products manually placed thereon to the lifting and transferring unit 4 .

[0035] In the above structure, the inflow lifting and transferring unit 1, the cache unit 2, the lifting and transferring unit 4 and the manual feeding unit 5 form a cache conveying system. When the panel product transported by the upstream equipment enters the inflow lifting and transferring unit 1, it can be processed according to the needs of the downstream equipment. If the downstream equipment needs the panel product, the inflow lifting and transferring unit 1 will convey the panel product forward to the lifting and transferring unit 4, and then the lifting and transferring unit 4 will locate and scan the code for identification and then convey it to the downstream equipment. If the downstream equipment temporarily does not need the panel product during the execution process, the inflow lifting and transferring unit 1 will convey the panel product laterally to the cache unit 2 for caching. When the downstream equipment fails to supply the panel products in time, the inflow lifting and transferring unit 1 can obtain the panel products from the cache unit 2, so as to ensure that the downstream equipment obtains the panel products in time. Compared with the prior art, the present invention can realize flexible caching and product transportation, and the upstream and downstream equipment do not need to stop and wait, and the transportation efficiency is higher. At the same time, the present invention, by setting the manual feeding unit 5, helps to manually check the abnormal panel products identified by the lifting and transferring unit 4, or facilitates the manual delivery of panel products to the lifting and transferring unit 4, so as to replenish the panel products for the downstream equipment in time. In addition, the present invention has many functions such as code scanning correction, which not only has stronger automation performance, but also better meets the process requirements.

[0036] In order to improve the buffer storage capacity, combined Figure 1 , Fig.10 and Fig.11 As shown, this embodiment includes two buffer units 2 , which are respectively arranged on the left and right sides of the inflow lifting and transferring unit 1 .

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

[0038] Furthermore, the cache conveying roller group 21 includes a cache conveying bracket 210, and a plurality of cache conveying roller shafts 211 parallel to each other are provided on the cache conveying bracket 210, and a plurality of cache conveying wheels 212 are evenly distributed on the cache conveying roller shaft 211. A cache driving roller shaft 213 is provided on the outer side of the cache conveying bracket 210, and the cache driving roller shaft 213 is vertically arranged below the end of the cache conveying roller shaft 211. The cache driving roller shaft 213 and the end of the cache conveying roller shaft 211 are matched with each other through a magnetic wheel assembly 214, and the cache conveying driving mechanism 23 includes a cache driving motor 215 for driving the cache driving roller shaft 213 to operate.

[0039] In order to make the cache bin structure compact, in the present embodiment, there is a gap 216 of preset width between two adjacent cache conveying rollers 211, and the multi-layer cache bin 22 includes a plurality of front vertical rods 220 and a plurality of rear vertical rods 221, and the front vertical rods 220 and the rear vertical rods 221 correspond to each other one by one, and a plurality of shelf cross rods 222 equally spaced vertically are fixed between the front vertical rods 220 and the rear vertical rods 221, and the front vertical rods 220, the rear vertical rods 221 and the shelf cross rods 222 can pass through the gap 216, and the plurality of shelf cross rods 222 located in the same plane form a group of shelves.

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

[0041] In the above structure, when the cache conveying roller group 21 receives and sends out the panel products, the cache conveying driving mechanism 23 drives the cache conveying roller group 21 to operate forward or reversely. In the process of caching the panel products, the cache bin lifting driving mechanism 24 drives the multi-layer cache bin 22 to rise layer by layer, so that the empty shelf moves to a position flush with the cache conveying roller group 21, so that the cache conveying roller group 21 can convey the panel products to the shelf in a straight manner. When the cache unit 2 replenishes the panel products to the inflow lifting and loading unit 1, the cache bin lifting driving mechanism 24 drives the multi-layer cache bin 22 to descend layer by layer. When the shelf falls to an appropriate height position, the panel products are placed on multiple cache conveying wheels 212. Based on the above structural principle, it can be seen that this embodiment can cache a large number of panel products based on the good cooperation between the cache conveying roller group 21 and the multi-layer cache bin 22. At the same time, the structural layout is reasonable, so that the cache unit 2 has a compact structure and occupies a small space.

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

[0043] The reversing transfer roller group 41 is used to receive the panel products delivered by the inflow lifting transfer unit 1, to deliver the panel products to the downstream equipment, and to cooperate with the manual feeding unit 5 to deliver the panel products;

[0044] The blocking mechanism 43 is disposed at the front end of the reversing transfer roller set 41, and the blocking mechanism 43 is used to resist the front end of the panel product;

[0045] The correction component 42 is arranged 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 code scanning component 44 is disposed above the reversing transfer roller group 41 , and the VCR code scanning component 44 is used to scan and identify the panel product.

[0047] Specifically, the reversing transfer roller group 41 includes a front and rear conveying roller group 410, a left and right conveying roller group 411, a front and rear conveying drive mechanism 412 and a left and right conveying drive mechanism 413. The front and rear conveying roller group 410 and the front and rear conveying drive mechanism 412 are both arranged on the lifting and transferring bracket 40. The front and rear conveying drive mechanism 412 drives the front and rear conveying roller group 410 to operate and convey the panel product forward. The lifting and transferring bracket 40 is provided with a lifting fixed plate 400. The lifting fixed plate 400 is provided with a lifting motion frame 401 and a lifting cylinder 402 for driving the lifting motion frame 401 to move up and down. The right conveying roller group 411 is arranged on the lifting and moving frame 401, and a plurality of avoidance gaps 414 are evenly distributed on the front and rear conveying roller groups 410. The left and right conveying roller groups 411 include a plurality of left and right conveying rollers 415. The left and right conveying rollers 415 can pass through the avoidance gaps 414. When the lifting cylinder 402 lifts the lifting and moving frame 401 upward, the left and right conveying rollers 415 are driven to protrude above the front and rear conveying roller groups 410. The left and right conveying driving mechanism 413 is used to drive the left and right conveying roller groups 411 to operate, and the panel products are conveyed to the manual feeding unit 5 by means of the plurality of left and right conveying 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 up and down, and the rollers in the front and rear conveying roller groups 410 and the left and right conveying roller groups 411 are staggered with each other. The left and right conveying rollers 415 located at the bottom can pass through the avoidance gap 414 located at the top. Therefore, when it is necessary to convey the panel products front and back, the lifting cylinder 402 drives the lifting motion frame 401 to fall back downward, and the front and rear conveying roller groups 410 play a conveying role for the panel products. When abnormal products are found, the lifting and transferring unit 4 needs to convey the abnormal panel products to the manual feeding unit 5. At this time, the lifting cylinder 402 lifts the lifting motion frame 401 upward, driving 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, and uses multiple left and right conveying rollers 415 to convey the panel products to the manual feeding unit 5.

[0049] This embodiment preferably has a VCR code scanning. Specifically, the VCR code scanning component 44 includes a code scanning front and back motion module 440. The motion end of the code scanning front and back motion module 440 is provided with a code scanning left and right motion module 441. The motion end of the code scanning left and right motion module 441 is provided with a VCR code scanning camera 442.

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

[0051] In the above structure, the left and right synchronous motion module 420 includes a linear motion module, and the left and right synchronous motion module 420 can drive the left and right correction rods to approach each other or relatively move away from each other, so that the left and right correction rods drive the left and right correction blocking rods 424 to push the panel product for correction. Not only is the correction efficiency high, but the corrected panel product can also be maintained in the center position on the reversing transfer roller group 41.

[0052] As a preferred method, see Fig. 9 The blocking mechanism 43 includes a lifting blocking cylinder 430 , a lifting blocking frame 431 is provided at the moving end of the lifting blocking cylinder 430 , and a plurality of blocking rods 432 are provided on the lifting blocking frame 431 .

[0053] In this embodiment, see Figure 2 The manual feeding unit 5 includes a manual feeding frame 50 , on which a manual feeding conveying 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 the present invention, the structure and principle of the manual feeding conveying roller set 51 can refer to the cache conveying roller set 21, and the manual feeding conveying roller set 51 and the cache conveying roller set 21 only need to have left and right conveying functions.

[0055] In a preferred embodiment of the present invention, the structure and principle of the inflow lifting and transferring unit 1 can refer to the reversing transfer roller group 41. The inflow lifting and transferring unit 1 and the reversing transfer roller group 41 need to have the function of transporting the panel products forward and backward, and also need to have the function of transporting the panel products left and right after lifting them.

[0056] See also Figure 1 This embodiment includes an offset lifting and transferring unit 3, which is arranged at the front side of the inflow lifting and transferring unit 1, and the lifting and transferring unit 4 is arranged at the right side of the offset lifting and transferring unit 3.

[0057] In this embodiment, when the upstream products flow in from the inflow lifting and transferring platform, the products can be lifted and transferred to the left or right and flow into the cache roller (or can directly flow to the offset lifting and transferring unit), the cache bin can be raised and lowered, and the single-sided material bin can cache 40 layers. When the upstream equipment does not produce in time, the products can flow out of the cache bin and then flow to the offset lifting and transferring unit. The offset lifting and transferring platform transfers the products in the Y direction to the outflow lifting and transferring unit, and then the correction component clamps the products to center the products. The VCR scans the code to read the information (the code scanning can cover the entire position of the product), and then the products flow into the downstream equipment. When the code scanning and reading system determines that there is an abnormal product, it will be lifted and moved horizontally to the manual workstation, and the abnormality will be handled manually. In addition, the manual workstation can also put products in, and then the products flow into the lifting and moving system and then enter the downstream equipment.

[0058] It should be noted that the scenario used in this embodiment is that the product outflow and inflow of the upstream device and the downstream device are offset, so this embodiment can be called an offset panel buffer device. Specifically in practical applications, due to the common display panel production line, the upstream and downstream devices cannot be offset or there is no buffer station, and the buffer station has a single function, resulting in the inability to synchronize the efficiency of the upstream and downstream devices, thus affecting the production efficiency of the entire line. Therefore, this embodiment provides a fully functional offset buffer device, please refer to Figure 1 The offset position relationship between the inflow lifting and transferring unit 1 and the lifting and transferring unit 4 is suitable for the scenario where the upstream and downstream devices are offset.

[0059] Embodiment 2

[0060] See also Fig.12 The difference between this embodiment and the first embodiment is that the lifting and transferring unit 4 is arranged at the front side of the inflow lifting and transferring unit 1.

[0061] It should be noted that in this embodiment, the outflow and inflow of products of the upstream device and the downstream device are aligned, so this embodiment can be called an in-line panel buffer device.

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