Description

Technical Field

[0001] This utility model relates to the field of temporary storage technology, and in particular to a first-in-first-out (FIFO) temporary storage machine. Background Technology

[0002] Temporary storage machines are used for temporary storage of materials. In existing patents, Chinese patent application number 202321014279.X discloses a multi-layer buffer device, including a transfer device, a rotating platform, and a multi-layer buffer mechanism. The transfer device can transfer batteries from the rotating platform to the multi-layer buffer mechanism. The multi-layer buffer mechanism includes a lifting component, a conveying component, and multi-layer buffer bins. The lifting component can drive the conveying component to move along a first direction. The multi-layer buffer bins include multiple buffer layers and a discharge layer, both of which are equipped with pull belts. Although this patent can achieve both temporary storage and discharge of materials, the temporary storage and discharge actions cannot be performed simultaneously. When temporarily storing materials, discharge cannot be performed; conversely, when discharging materials, temporary storage cannot be performed, resulting in low production efficiency. Therefore, the shortcomings are quite obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a first-in-first-out temporary storage machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A first-in-first-out (FIFO) temporary storage machine includes multiple temporary storage conveyor lines arranged at equal intervals from top to bottom, a loading robot at one end of the multiple temporary storage conveyor lines, a unloading robot at the other end of the multiple temporary storage conveyor lines, and a conveying device located below the bottom temporary storage conveyor line. The temporary storage conveyor lines include two linear drive modules arranged opposite to each other and parallel to each other, and temporary storage platforms installed at the drive ends of the two linear drive modules. The linear drive modules are arranged in a straight line with a loading position, a temporary storage position, and an unloading position. The loading robot is arranged corresponding to the loading position, and the unloading robot is arranged corresponding to the unloading position. The conveying surface of the conveying device is exposed between the two linear drive modules. The linear drive modules are used to drive the temporary storage platform to move between the loading position, the temporary storage position, and the unloading position.

[0005] Furthermore, the loading robot and / or unloading robot includes a lifting drive mechanism disposed at one end of the linear drive module and a pick-and-place mechanism mounted on the lifting end of the lifting drive mechanism, the pick-and-place mechanism being located between the two linear drive modules.

[0006] Furthermore, the picking and placing mechanism includes a mounting frame installed on the lifting end of the lifting drive mechanism and multiple suction groups arranged parallel to the mounting frame, with the two outermost suction groups each equipped with at least one clamping mechanism.

[0007] Furthermore, the suction assembly includes a crossbar mounted on the mounting frame and multiple suction cup assemblies arranged in a straight line on the crossbar.

[0008] Furthermore, the clamping mechanism includes a fixed plate mounted on the crossbar, a lifting drive mounted on the fixed plate, a lifting plate mounted on the lifting end of the lifting drive, and a clamping assembly mounted on the lifting plate.

[0009] Furthermore, the pick-and-place mechanism also includes a spacing adjustment module mounted on the mounting frame. A group of suction units on the outer side is mounted on the adjustment end of the spacing adjustment module. The spacing adjustment module is used to drive the group of suction units to move closer to or further away from the adjacent suction units.

[0010] Furthermore, the temporary storage platform includes a carrier plate mounted on the drive end of the two linear drive modules and multiple positioning rods mounted on the carrier plate. The multiple positioning rods and the top surface of the carrier plate enclose a temporary storage space.

[0011] Furthermore, the conveying device includes a roller conveying mechanism located below the bottom temporary conveying line and two centrally positioned lifting mechanisms disposed on the roller conveying mechanism. The two centrally positioned lifting mechanisms are respectively disposed corresponding to the loading robot and the unloading robot.

[0012] Furthermore, the centering positioning and lifting mechanism includes a mounting base installed on the frame of the roller conveyor mechanism, two centering plates arranged parallel above the conveying surface of the roller conveyor mechanism, a centering drive module installed on the mounting base for driving the two centering plates to move closer or further apart from each other, multiple lifting plates that are lifted and lowered on the roller conveyor mechanism, and a lifting drive module installed on the mounting base for driving the multiple lifting plates to move up and down. The lifting plates are located between two adjacent rollers of the roller conveyor mechanism.

[0013] Furthermore, the conveying device also includes two sensors respectively installed at both ends of the roller conveying mechanism and a barcode scanner located above one or both ends of the roller conveying mechanism.

[0014] The beneficial effects of this utility model are as follows: In practical applications, initially, the temporary storage platform is located at the temporary storage position. When materials are conveyed to the conveying device, and the conveying device delivers the materials to the position corresponding to the loading position, the loading robot picks up the materials corresponding to the loading position and lifts them up. Then, two linear drive modules of any temporary storage conveyor line drive the temporary storage platform to move to the loading position and position it below the materials picked up by the loading robot. The loading robot then places the materials on the temporary storage platform. Next, the two linear drive modules drive the temporary storage platform back to the temporary storage position. After the loading robot picks up and lifts the next material, the two linear drive modules drive the temporary storage platform to move to the loading position again, and the loading robot places the materials on the temporary storage platform again. This process is repeated to achieve the stacking of materials on the temporary storage platform. When a temporary storage platform is full, another temporary storage conveyor line temporarily stores and stacks the materials picked up by the loading robot, thus achieving multi-layer temporary storage conveyor lines to sequentially store and stack materials. When materials stacked on a temporary storage platform need to be unloaded, two linear drive modules of any temporary storage conveyor line drive the temporary storage platform to the unloading position, positioned below the unloading robot. The unloading robot then picks up the top layer of material from the temporary storage platform. The two linear drive modules then drive the temporary storage platform to the storage position, where the unloading robot places the material onto the conveyor. The conveyor outputs the material, and the unloading robot resets. The two linear drive modules then drive the temporary storage platform to the unloading position, positioned below the unloading robot. This process is repeated to dismantle and output the materials stacked on the temporary storage platform. Once the materials on one temporary storage platform have been dismantled, the unloading robot dismantles the temporary storage platforms on another layer of the temporary storage conveyor line. Specifically, in a multi-layer temporary storage conveyor line, the temporary storage platform where materials were first stacked is dismantled and output first, achieving a first-in, first-out (FIFO) principle. This invention utilizes a loading robot and an unloading robot to work in conjunction with a multi-layer temporary storage conveyor line to stack and temporarily store or cut and output materials in a first-in-first-out manner. The stacking and temporary storage work and the cutting and output work do not interfere with each other, which greatly improves the efficiency of stacking and temporary storage and cutting and output.

Detailed Implementation To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] like Figures 1 to 6 As shown, this utility model provides a first-in-first-out (FIFO) temporary storage machine, which includes a multi-layer temporary storage conveyor line 1 arranged at equal intervals from top to bottom, a loading robot 2 located at one end of the multi-layer temporary storage conveyor line 1, a unloading robot 3 located at the other end of the multi-layer temporary storage conveyor line 1, and a conveying device 4 located below the bottom temporary storage conveyor line 1. The temporary storage conveyor line 1 includes two opposing and parallel linear drive modules 5 and a temporary storage platform 6 installed at the drive end of the two linear drive modules 5. The linear drive modules 5 are arranged in a straight line with a loading position, a temporary storage position, and an unloading position. The loading robot 2 is arranged corresponding to the loading position, and the unloading robot 3 is arranged corresponding to the unloading position. The conveying surface of the conveying device 4 is exposed between the two linear drive modules 5. The linear drive modules 5 are used to drive the temporary storage platform 6 to move between the loading position, the temporary storage position, and the unloading position. This FIFO temporary storage machine temporarily stores materials, preferably board components (such as circuit boards).

[0023] In practical applications, initially, the temporary storage platform 6 is located at the temporary storage position. When the material is conveyed to the conveying device 4, and the conveying device 4 conveys the material to the position corresponding to the loading position, the loading robot 2 picks up the material corresponding to the loading position and lifts the material. Then, the two linear drive modules 5 of any temporary storage conveyor line 1 drive the temporary storage platform 6 to move to the loading position and position it below the material picked up by the loading robot 2. Then, the loading robot 2 places the material on the temporary storage platform 6. Next, the two linear drive modules 5 drive the temporary storage platform 6 to move back to the temporary storage position. After the loading robot 2 picks up and lifts the next material, the two linear drive modules 5 drive the temporary storage platform 6 to move to the loading position again, and the loading robot 2 places the material on the temporary storage platform 6 again. The above steps are repeated to achieve the stacking of materials on the temporary storage platform 6. When a temporary storage platform 6 is full, another temporary storage conveyor line 1 temporarily stores and stacks the materials picked up by the loading robot 2, so as to realize that the multi-layer temporary storage conveyor line 1 will temporarily store and stack the materials in sequence. When it is necessary to unload the materials stacked on the temporary storage platform 6, the two linear drive modules 5 of any temporary storage conveyor line 1 drive the temporary storage platform 6 to the unloading position and position it below the unloading robot 3. Then, the unloading robot 3 picks up the top layer of material on the temporary storage platform 6, and the two linear drive modules 5 drive the temporary storage platform 6 to the temporary storage position. Then, the unloading robot 3 places the material on the conveying device 4, the conveying device 4 outputs the material, and then the unloading robot 3 resets. Then, the two linear drive modules 5 drive the temporary storage platform 6 to the unloading position and position it below the unloading robot 3. The above steps are repeated to realize the unloading and output of the materials stacked on the temporary storage platform 6. When the materials on one temporary storage platform 6 are unloaded, the unloading robot 3 unloads the materials on the temporary storage platform 6 of another layer of temporary storage conveyor line 1. Specifically, in the multi-layer temporary storage conveyor line 1, the temporary storage platform 6 where the temporary storage materials are stacked first is unloaded and the materials are output first to realize first-in-first-out. This invention utilizes a loading robot 2 and a unloading robot 3 to work in coordination with a multi-layer temporary storage conveyor line 1 to stack and temporarily store or cut and output materials in a first-in-first-out manner. The stacking and temporary storage work and the cutting and output work do not affect each other, which greatly improves the efficiency of stacking and temporary storage and cutting and output.

[0024] In this embodiment, the loading robot 2 and / or unloading robot 3 includes a lifting drive mechanism 10 disposed at one end of the linear drive module 5 and a pick-and-place mechanism 11 mounted on the lifting end of the lifting drive mechanism 10. The pick-and-place mechanism 11 is located between the two linear drive modules 5. In practical applications, the lifting drive mechanism 10 drives the pick-and-place mechanism 11 to lift and place materials.

[0025] In this embodiment, the picking and placing mechanism 11 includes a mounting frame 12 installed on the lifting end of the lifting drive mechanism 10 and multiple sets of suction groups 13 arranged parallel to the mounting frame 12. The two outermost suction groups 13 are each provided with at least one clamping mechanism 14. In practical applications, after the multiple suction groups 13 pick up a material, the clamping mechanism 14 clamps the edge of the material to prevent the material from falling, thus improving the stability of picking up the material.

[0026] In this embodiment, the suction assembly 13 includes a crossbar 15 disposed on the mounting frame 12 and a plurality of suction cup assemblies 16 arranged in a straight line on the crossbar 15. The material is tightly sucked up by the plurality of suction cup assemblies 16 in the multiple suction assemblies 13, thereby improving the stability of material suction.

[0027] In this embodiment, the clamping mechanism 14 includes a fixed plate 17 mounted on the crossbar 15, a lifting driver 18 mounted on the fixed plate 17, a lifting plate 19 mounted on the lifting end of the lifting driver 18, and a clamping assembly 20 mounted on the lifting plate 19; specifically, the lifting driver 18 can be a cylinder. When multiple suction groups 13 clamp the material, the lifting driver 18 drives the lifting plate 19 and the clamping assembly 20 to descend, so that the edge of the material is located at the clamping end of the clamping assembly 20, and then the clamping end of the clamping assembly 20 closes to clamp the edge of the material.

[0028] In this embodiment, the picking and placing mechanism 11 further includes a spacing adjustment module 21 mounted on the mounting frame 12. A set of suction groups 13 on the outer side is mounted on the adjustment end of the spacing adjustment module 21. The spacing adjustment module 21 is used to drive the set of suction groups 13 to move closer to or further away from the adjacent suction groups 13. According to the length or width of different materials, the spacing adjustment module 21 adjusts the position of the set of suction groups 13 on the outer side to enable the picking of materials of different specifications (length or width).

[0029] In this embodiment, the temporary storage platform 6 includes a carrier plate 22 mounted on the drive end of two linear drive modules 5 and a plurality of positioning rods 23 mounted on the carrier plate 22. The plurality of positioning rods 23 and the top surface of the carrier plate 22 enclose a temporary storage space. Materials are stacked and temporarily stored in the temporary storage space. The carrier plate 22 supports the materials, and the plurality of positioning rods 23 abut against the edges of the materials to position them.

[0030] In this embodiment, the conveying device 4 includes a roller conveying mechanism 24 located below the bottom temporary conveying line 1 and two centrally positioned lifting mechanisms 25 disposed on the roller conveying mechanism 24. The two centrally positioned lifting mechanisms 25 are respectively disposed corresponding to the loading robot 2 and the unloading robot 3.

[0031] When materials are conveyed to the conveying device 4, the conveying device 4 transports the materials to the loading position. At this time, the materials are located at a centrally positioned lifting mechanism 25 and below the loading robot 2. The centrally positioned lifting mechanism 25 first centers the materials and then lifts them, causing the materials to detach from the conveying device 4. Then, the loading robot 2 accurately picks up the materials and rises. When the unloading robot 3 disassembles the materials temporarily stored on the temporary storage platform 6, the unloading robot 3 picks up the materials and places them on the lifting end of the corresponding centrally positioned lifting mechanism 25. The centrally positioned lifting mechanism 25 centers the materials and then places them on the conveying device 4. The conveying device 4 outputs the centered materials, ensuring accurate output.

[0032] In this embodiment, the centering and lifting mechanism 25 includes a mounting base 26 mounted on the frame of the roller conveyor mechanism 24, two centering plates 27 arranged parallel to the conveying surface of the roller conveyor mechanism 24, a centering drive module 28 mounted on the mounting base 26 for driving the two centering plates 27 to move closer or further apart, multiple lifting plates 29 vertically mounted on the roller conveyor mechanism 24, and a lifting drive module 30 mounted on the mounting base 26 for driving the multiple lifting plates 29 to move up and down. The lifting plates 29 are located between two adjacent rollers of the roller conveyor mechanism 24. In practical applications, the centering drive module 28 drives the two centering plates 27 to move closer to each other to tap and position the sides of the material, thereby centering the material; the lifting drive module 30 drives the multiple lifting plates 29 to move up and down, so as to lift or place the material on the conveyor device 4.

[0033] Specifically, a support wheel 33 is rotatably connected to the top of the lifting plate 29. In practical applications, the support wheel 33 contacts the material, reducing material wear.

[0034] In this embodiment, the conveying device 4 further includes two sensors 31 respectively installed at both ends of the roller conveying mechanism 24, and a barcode scanner 32 located above one or both ends of the roller conveying mechanism 24. In practical applications, one sensor 31 is used to sense the material input to the conveying device 4, and the other sensor 31 is used to sense the material output to the conveying device 4. In addition, the barcode scanner 32 is used to read the identification code (QR code or barcode, etc.) on the input or output material.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
