The material transfer device transfers the jig box 1 to the second position, the jig pick-up and placement device 6 takes out the jig 102 carrying the material from the jig box 1 at the second position, the unloading device 9 grabs the material from the jig 102 carrying the material taken out by the jig pick-up and placement device 6 and transfers it to the unloading platform 8, and the jig pick-up and placement device 6 puts the jig 102 back into the jig box 1 at the second position. The material is in a horizontal state during the transfer process.

[0066] It should be noted that the jig material box 1 of the technical solution of the present application is provided with multiple jig material boxes 1 on the material transfer device, and the circulation of multiple jig material boxes 1 can maximize the efficiency of the developer, which not only meets the requirements of the static time of the product, but also can realize uninterrupted feeding to the developer and improve efficiency. In this way, the degree of manual intervention in this process is greatly reduced, and the automation and digitization rate is also improved.

[0067] Specifically, the rack 10 is horizontally erected on the ground as the installation base of the entire device, and has a certain structural strength. Preferably, the rack 10 of the technical solution of the present application is a rectangular hollow structure. For ease of understanding, the length direction of the rack 10 is positioned in the X direction, the width direction is positioned in the Y direction, and the height direction is positioned in the Z direction.

[0068] like Figure 1 and Figure 5 As shown, the material transfer device is arranged inside the frame 10, and the material transfer device includes two sets of lifting devices 3 and two sets of horizontal conveying devices 5. The two sets of horizontal conveying devices 5 are arranged at intervals up and down, and the two sets of lifting devices 3 are respectively arranged at both ends of the two sets of horizontal conveying devices 5. The conveying directions of the two sets of horizontal conveying devices 5 are opposite. The two sets of lifting devices 3 are respectively arranged at both ends of the horizontal conveying devices 5.

[0069] The horizontal conveying device 5 can be a conventional double-speed chain flow channel 303, which is driven by a servo motor and is mainly used for transmitting or temporarily storing material boxes. There can be at least one fixture material box 1 for the length of each horizontal conveying device 5.

[0070] The lifting device 3 is arranged vertically, and is mainly responsible for the lifting and lowering of the jig material box 1 between the upper horizontal conveying device 5 and the lower horizontal conveying device 5 during the circulation process of the jig material box 1. And cooperate with the jig pick-up and placement device 6 to take out or put back the jig 102 layer by layer from the jig material box 1. The lifting device 3 includes a Z-axis module 301, a positioning cylinder 302 and a flow channel 303. The positioning cylinder 302 and the flow channel 303 form a whole, and the whole formed by the positioning cylinder 302 and the flow channel 303 can perform lifting and lowering movements along the Z-axis module 301 under the action of the driving member. It should be noted that the Z-axis module 301 of the present application can be a transmission structure with a linear reciprocating transmission function in the prior art. Preferably, it is a threaded screw substructure. The positioning cylinder 302 is used to fix the jig material box 1 on the flow channel 303 to prevent the jig material box 1 from moving during the lifting process and to ensure the accurate position when taking and placing the jig 102. The flow channel 303 uses a double-speed chain to transmit the jig material box 1, which can carry and transmit a large weight and can be connected to the horizontal conveying device 5.

[0071] like Figure 1 and Figure 6As shown, both the loading platform 4 and the unloading platform 8 can extend out of the frame 10 or retract from the outside of the frame 10, the loading platform 4 is located at one end of the frame 10 in the length direction, and the unloading platform 8 is located at the other end of the frame 10 in the length direction, and the end of the frame 10 with the loading platform 4 is the loading end, and the end of the frame 10 with the unloading platform 8 is the unloading end.

[0072] Both the loading platform 4 and the unloading platform 8 include a telescopic structure, which can extend out of the frame 10 or retract into the frame 10. The telescopic structure includes a telescopic table 401, an X-axis telescopic cylinder 403, and a linear guide 404. The linear guide 404 is horizontally arranged, and the direction of the linear guide 404 is along the X-axis direction, and the linear guide 404 is fixedly installed on the frame 10. The telescopic table 401 is horizontally arranged above the linear guide 404, and the telescopic table 401 and the linear guide 404 are slidably matched, and the telescopic table 401 can slide along the direction of the linear guide 404. The body of the X-axis telescopic cylinder 403 is installed on the frame 10, and the X-axis telescopic cylinder 403 can reciprocate along the X-axis direction, and the X-axis telescopic cylinder 403 drives the guide of the linear guide 404 of the telescopic table 401 to extend out of the frame 10 or retract into the frame 10. It should be noted that the X-axis telescopic cylinder 403 of the present application can be any device that performs linear reciprocating motion in the prior art, such as a telescopic cylinder or a telescopic rod.

[0073] Furthermore, a clamping cylinder 402 is provided on the telescopic table 401, and the clamping cylinder 402 acts on the peripheral edge of the material. Multiple clamping cylinders 402 fix or loosen the material on the telescopic table 401. In a feasible implementation, at least one or more sets of clamping cylinders 402 are provided at both ends of the telescopic table 401 along the X-axis direction, so as to facilitate the fixed placement of the material on the telescopic table 401, and prevent the thinner product from sagging in the middle, and tightening by the clamping cylinder 402 improves the automation of the system. It should be supplemented that only the narrow areas around the large-sized soft board can be contacted.

[0074] like Figure 1 and Figure 7 As shown, the loading device 2 acts on the loading platform 4, and the unloading device 9 acts on the unloading platform 8. Both the loading device 2 and the unloading device 9 include an X-axis support shaft 201, a Z-axis support shaft 202, a visual component, and a grabbing component. The structures and working principles of the loading device 2 and the unloading device 9 are the same, and this application takes one group as an example for explanation. The visual component and the grabbing component are relatively fixed, and both the visual component and the grabbing component can move along the trajectory of the X-axis support shaft 201, and both the visual component and the grabbing component can also move along the Z-axis support shaft 202.

[0075] The vision component and the grasping component are relatively fixedly arranged on a rectangular plate, the rectangular plate is located below the Z-axis support shaft 202, and the Z-axis support shaft 202 is movably arranged on the X-axis support shaft 201. It should be noted that the X-axis support shaft 201 is provided with a driving device for driving the Z-axis support shaft 202 to move along the X direction, and the Z-axis support shaft 202 is provided with a driving device for driving the rectangular plate to move along the Z direction.

[0076] Specifically, the visual component includes an ID camera 203 and a positioning camera 206. The ID camera 203 is used to read and identify the product code, and then upload the system to determine whether the product is a temporary product or a passed product. If it is a temporary product, it will be bound to the code of the stored fixture 102. The positioning camera 206 is set at two opposite corners of the rectangular plate to locate the position and posture of the product.

[0077] The grabbing assembly includes a suction cup 208, an anti-drop claw 205, and a clamping cylinder 207. The anti-drop claw 205 is used to hook the edge of the product, bear part of the weight and prevent the product from falling. In a feasible implementation, a set of release claws is respectively provided on two opposite sides of the rectangular block. The clamping cylinder 207 is used to clamp the edges of the four corners of the product. The suction cup 208 is used to absorb the edge of the material and cooperate with the clamping cylinder 207 to ensure that the product does not deform when grabbing thinner products.

[0078] When clamping the material on the platform or in the fixture 102, first use the clamping cylinder 207 to clamp the four corners of the product, then the device for fixing the material on the platform or fixture 102 is opened, and the adsorbable area on the edge of the product is avoided. The suction cup 208 then descends to adsorb the area, and finally the material can be taken away. In this way, the product can be clamped by external force during the entire transmission process, avoiding the risk of sagging or falling due to the large size or thinness of the product.

[0079] In a preferred embodiment, the lower end of the Z-axis support shaft 202 is connected to the middle of the rectangular plate with a fine-tuning mechanism 204, which includes Y-axis fine-tuning and Z-axis rotation fine-tuning, and is used to fine-tune the position and posture of the product. It should be noted that the fine-tuning mechanism 204 can adopt a connection structure that can achieve Y-axis fine-tuning and Z-axis rotation fine-tuning in the prior art.

[0080] like Figure 1 , Figure 8 as well as Fig. 9As shown, a plurality of jig 102 placement sites are arranged at intervals along the Z-axis direction inside the jig material box 1, and the jig material box 1 includes a material taking and discharging opening opened on one side. A fixing clamp 1021 is arranged on the peripheral edge of the jig 102, and the fixing clamp 1021 acts on the bearing edge of the material to fix the material on the jig 102 or loosen it. Specifically, the jig material box 1 is mainly used to store the jig 102, and the side wall of the material box is provided with a gap partition groove, and the jig 102 is stored in the partition groove layer by layer. Multiple jigs 102 can be stored in one material box, and four or more jig material boxes 1 can be stored in one machine. The number of jigs 102 stored in each jig material box 1 and the number of material boxes in the machine are set according to the actual required loading and unloading speed and the temporary storage time required by the product, so as to ensure that the temporary storage time and loading and unloading speed are met while the material bin in the machine can be circulated uninterruptedly. The fixing clamp 1021 on the jig 102 is normally in a clamping state through a torsion spring, and the product is always in a clamping state in the jig 102, ensuring that the product remains flat in the jig 102 without sagging.

[0081] like Figure 1 , Fig.10 as well as Fig.11 As shown, the jig pick-up and placement device 6 is arranged correspondingly to the lifting device 3. The jig pick-up and placement device 6 of the present application is provided with two jig pick-up and placement devices 6, and the two jig pick-up and placement devices 6 are respectively located at the front of the corresponding lifting device 3 in the Y direction. The jig pick-up and placement device 6 includes a fork 603, and the jig pick-up and placement device 6 also includes a first drive component that can make the fork 603 translate, extend or retract in the Y direction, and the jig pick-up and placement device 6 also includes a second drive component that can make the fork 603 translate and lift in the Z direction. The fork 603 is composed of a plurality of long bars, which can be extended into the material box to take out the jig 102. The side of the jig pick-up and placement device 6 is provided with a guardrail side panel 602 to prevent the jig 102 from accidentally falling out of the jig pick-up and placement device 6. The jig opening mechanism 601 is provided on the jig pick-up and placement device 6, and the jig opening mechanism 601 is arranged correspondingly to the fixed clamp 1021 on the jig 102 and can act on the fixed clamp 1021 to open the fixed clamp 1021.

[0082] The technical solution of the present application is aimed at the problem that a large-sized soft board has only a narrow area around it that can be contacted, and the product needs to be temporarily stored, stationary and loaded under the condition that it needs to be kept flat and not deformed at all times. The present application adopts the method of clamping and adsorbing the edge of the product during transportation, placing the product in a jig 102 to clamp the edge of the product during temporary storage, and the transportation mechanism and the jig 102 cooperate with each other to ensure that the product is always kept flat and not bent during the process of transportation, temporary storage and loading.

[0083] It should be noted that the first position is the position of the lifting device 3 on the feeding side, and the lifting device 3 drives the fixture material box 1 to move along the Z-axis direction until the target layer of the fixture material box 1 is flush with the fixture pick-up and placement device 6 in the Z direction, and the fork 603 of the fixture pick-up and placement device 6 moves along the Y direction to extend into the fixture material box 1 to take out the target fixture 102. Similarly, the second position is the position of the lifting device 3 on the unloading side.
