Description

Technical Field

[0001] The utility model relates to the field of overhead crane material handling equipment, in particular to a storage repository and a material handling system. Background Art

[0002] In a material handling system, in order to store more cassettes at each processing equipment, a buffer structure is usually provided at the processing equipment to store the cassettes.

[0003] The invention patent with the publication number of CN106463442A discloses a temporary storage device for a carrier, which caches the carrier through a plurality of sliding buffer areas of the temporary storage device. At the same time, the carrier is transferred between different positions by cooperating with the OHT and the interval trolley and the sliding buffer area.

[0004] In this structure, the actual need for taking and placing the carrier at the side of the loading area is not considered. Since the loading area is inside the sliding buffer area in the extended state, it is easy for the sliding buffer area to collide with the operator or the taking and placing equipment performing the taking and placing operation at the side of the loading area when the sliding buffer area extends, which poses a safety hazard. And if such a problem is to be avoided, the height of the sliding buffer area needs to be set high enough, which will increase the height and cost of the equipment. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above problems existing in the prior art, and provide a storage repository and a material handling system.

[0006] The purpose of the utility model is achieved by the following technical solutions:

[0013] Preferably, a control panel, a buzzer corresponding to each pick-and-place position, and / or an emergency stop button and / or a start button are arranged at the pick-and-place docking interface.

[0014] Preferably, the temporary storage assembly includes a temporary storage device and a transfer mechanism. The transfer mechanism includes a moving component and a grasping component driven by the moving component to translate and lift. The moving component can drive the grasping component to move directly above the positioning stage and directly above the temporary storage carrier of the temporary storage device.

[0015] Preferably, the moving component includes a translation mechanism. The translation mechanism includes a sliding frame that can reciprocate along a slide rail.

[0018] The advantages of the technical solution of the present utility model are mainly reflected in:

[0019] The present utility model provides a pick-and-place docking interface on the side of the frame and a temporary storage assembly above the pick-and-place docking interface on the frame. It can not only perform pick-and-place operations from the top of the pick-and-place docking interface through the temporary storage assembly, but also perform pick-and-place operations from the side of the pick-and-place docking interface.

[0030] Embodiment 1

[0031] The following describes the storage repository disclosed by the utility model in conjunction with the drawings, as shown in the attached Figure 1As shown in the figure, it includes a frame 100, on which a temporary storage component 200 is provided. The temporary storage component 200 is used to provide multiple positions for storing multiple cassettes 400 simultaneously. The cassette 400 is used to layer and hold sheet-like workpieces such as wafers, substrates, and glass plates. Its specific structure can be designed according to needs and will not be elaborated here.

[0032] As shown in the attached Figure 1 and attached Figure 2 figures, the temporary storage component 200 includes a temporary storage device 210 and a transfer mechanism 220. The transfer mechanism includes a moving component 221 and a grasping component 222 driven by it to translate and lift. The moving component 221 can drive the grasping component 222 to move directly above the temporary storage carrier 211 of the temporary storage device 210.

[0033] In the first embodiment, the temporary storage devices 210 are arranged in a row and distributed along the length direction of the frame 100. The number of the row of temporary storage devices 210 can be designed according to needs and is not limited here. The temporary storage device 210 can be a temporary storage carrier 211 for carrying and limiting the cassette 400. A sensor (not shown in the figure) for detecting whether there is a cassette 400 on it can be provided on the temporary storage carrier 211, such as a known proximity switch, a through-beam sensor, etc. The temporary storage carrier 211 is fixed on a layer of brackets of the frame 100. At this time, the moving component 221 can drive the grasping component 222 to move along the first horizontal direction X, the second horizontal direction Y, and the longitudinal direction Z. The first horizontal direction X is defined as the length direction of the frame 100, the second horizontal direction Y is perpendicular to the first horizontal direction X, and the longitudinal direction Z is the vertical direction.

[0034] In the second embodiment, as shown in the attached Figure 1 and attached Figure 3 figures, the temporary storage devices 210 are also arranged in a row and distributed along the first horizontal direction X. The temporary storage devices 210 also include temporary storage carriers 211. And the temporary storage carrier 211 is connected to a translation component 212, and the translation component drives the temporary storage carrier 211 to move between a first position and a second position along the second horizontal direction Y. The structure of the translation component 212 can be designed according to needs. For example, the temporary storage carrier 211 is slidably arranged on a guide rail, and the translation component is a cylinder, a hydraulic cylinder, a linear motor, a linear module, or other feasible devices, or the translation component includes a synchronous belt mechanism and a motor for driving the synchronous belt mechanism, etc. At the same time, the temporary storage carrier also includes a baffle 213, and the baffle 213 is distributed on the other three sides of the cassette except the inlet and outlet sides, so as to effectively ensure the stability of the cassette during the movement of the temporary storage carrier 211.

[0035] At this time, as shown in the attached Figure 1 and attached Figure 2As shown, the moving component 221 only needs to drive the grasping component 222 to move in the first horizontal direction X and the longitudinal direction Z. At the same time, the grasping component 222 is located outside the frame 100.

[0036] Correspondingly, when the temporary storage carrier 211 is at the first position, the temporary storage carrier 211 is located below the translation path of the grasping component 222. At this time, the temporary storage carrier 211 is located outside the frame 100, and the grasping component 222 can move directly above the temporary storage carrier 211 at the first position to pick up and place the cartridge 400. When at the second position, the temporary storage carrier 211 is located on the side of the translation path of the grasping component 222. At this time, the temporary storage carrier 211 is located inside the frame 100, and the temporary storage carrier 211 will not interfere with the downward movement of the grasping component 222.

[0037] Of course, in the structure of the second embodiment, the number of layers of the temporary storage 210 is not limited to one layer, that is, the temporary storage component 200 includes multiple layers of the temporary storage 210, and multiple temporary storage carriers 210 of each layer of the temporary storage 210 are arranged side by side along the length direction of the frame 100. Preferably, as shown in the appendix Figure 1 As shown, the number of layers of the temporary storage 210 is two or three layers, and the positions of the multiple layers of temporary storage 210 correspond to each other in the longitudinal direction Z. In this structure, if it is necessary to pick up and place the cartridge 400 of a lower temporary storage carrier 211 through the transfer mechanism, the temporary storage carrier 211 of the temporary storage 210 directly above the lower temporary storage carrier 211 needs to be switched to the second position for avoidance.

[0038] As shown in the appendix Figure 4 As shown, the moving component 221 includes a translation mechanism 223 for realizing the translation of the grasping component in the first horizontal direction X. The translation mechanism 223 includes a sliding frame 225 that can reciprocate along the slide rail 224. The slide rail 224 extends along the first horizontal direction X. A translation drive motor is provided on the sliding frame 225. The translation drive motor is connected to a drive wheel 226 that rotates by itself. The drive wheel 226 is connected to an open belt 227. The open belt 227 extends along the extension direction of the slide rail and its two ends are fixed on the fixed clamp block 228. During operation, the translation drive motor drives the drive wheel 226 to rotate. Since the position of the open belt 227 is fixed, the drive wheel 226 moves relative to the open belt 227, thereby driving the sliding frame 225 to slide along the slide rail 224. Further, in order to ensure sufficient contact between the drive wheel 226 and the open belt 227, auxiliary rollers 229 are provided on the sliding frame 225 on both sides of the drive wheel 226.

[0039] The structure for driving the lifting of the grasping component in the moving component and the specific structure of the grasping component 222 may be known technologies and are not the innovations of the present utility model, so no further description will be given here.

[0040] As shown in the Figure 1 accompanying drawings, a pick-and-place docking interface 300 is further provided on the side of the frame 100 and is located below the temporary storage component 200. The pick-and-place docking interface 300 includes at least one pick-and-place position. The pick-and-place position includes a positioning carrier 310 for carrying and positioning the cartridge 400. One side of the positioning carrier 310 is the pick-and-place operation side. The pick-and-place docking interface 300 further includes a detection device 320 for detecting whether there is a pick-and-place operation on the pick-and-place operation side. The detection device 320 is, for example, an image acquisition device, or a detection grating or other feasible devices, and even a known human body infrared sensor, etc. During use, the cartridge can be manually placed at the pick-and-place position, or the cartridge at the pick-and-place position can be manually removed.

[0041] As shown in the Figure 5 accompanying drawings, a rough positioning device 330 and a fine positioning device 340 are further provided on the positioning carrier 310. The rough positioning device 330 is a guiding block provided on the positioning carrier 310 and matching the bottom contour of the cartridge 400. The top corners of the guiding block guide the cartridge 400 through chamfered slopes. The fine positioning device 340 is a positioning pin provided on the positioning carrier 310 and matching the positioning holes or grooves at the bottom of the cartridge 400.

[0042] Meanwhile, a in-place detection sensor 360 for determining whether there is a cartridge 400 at the positioning carrier 310 is provided at the pick-and-place position. The positioning carrier 310 is provided with holes or grooves for the in-place detection sensor 360 to detect. The in-place detection sensor 360 can be a known proximity sensor.

[0043] A presence / absence detection sensor 350 is further provided at the pick-and-place position for determining whether there is a cartridge 400 at a predetermined height above the positioning carrier 310, so as to facilitate accurately controlling the moving height of the grasping component 222. The presence / absence detection sensor 350 can be provided on the frame 100 around the positioning carrier 310 or on the positioning carrier. It can be a known opposed sensor, self-reflection sensor or proximity sensor, etc., and is specifically selected according to needs and is not limited here.

[0044] Further, due to differences in the types of the magazine 400, the workpieces loaded therein, the positions to be moved to, etc., two-dimensional codes, barcodes, electronic tags, etc. are attached to the magazine 400 to store relevant information such as the ID of each magazine 400. Correspondingly, a code scanning device and / or a tag reading device 370 are provided at the picking and placing position. Preferably, a tag reading device 370 for reading RFID tag information is provided on the positioning stage 310.

[0045] The positioning stage 310 can be directly disposed on a stage, and its periphery is open. At this time, any one of the three sides of the positioning stage 310 except the side connected to the frame 100 can be used as the picking and placing operation side.

[0046] As shown in the Figure 1 , Figure 5 accompanying drawings, the positioning stage is disposed in a side frame 380 on the side of the frame. The top of the side frame 380 has an inlet / outlet 381 corresponding to each positioning stage, and an operation port 382 corresponding to the picking and placing operation side of each picking and placing position is provided on the side of the side frame 380. At this time, the picking and placing operation side is the side of the positioning stage 310 away from the frame 100. Correspondingly, the detection device 320 can be a detection grating disposed on the left and right sides of the operation port 382.

[0047] Moreover, the number of the picking and placing positions can be one or multiple. Preferably, there are two picking and placing positions arranged side by side along the length direction of the frame 100. Each picking and placing position corresponds to an operation port 382. One of the two operation ports 382 is for picking materials, and the other is for placing materials.

[0048] Correspondingly, the moving assembly 221 can also drive the grasping assembly 222 to move to directly above each picking and placing position, so that the transfer mechanism can pick and place the magazine 400 at the picking and placing docking port 300.

[0049] As shown in the Figure 5 accompanying drawings, a control panel 390, a buzzer 301 and / or an emergency stop button 302 corresponding to each picking and placing position are further provided on the side frame, so as to facilitate emergency control during manual picking and placing of the magazine 400. Of course, a start button corresponding to each operation port can also be provided on the side frame, which is used to send a material picking signal when the magazine 400 is placed from the side of the picking and placing position.
