[0001] This application relates to the field of material storage equipment, and particularly to an expandable intelligent material storage equipment. Background Art

[0002] Warehousing is a link in the logistics process. The application of intelligent warehousing ensures the speed and accuracy of data input in all aspects of warehouse management of goods, enables enterprises to timely and accurately grasp the real data of inventory, and reasonably maintain and control the inventory of enterprises. Through scientific coding, it is also convenient to manage the batches, shelf life, etc. of the goods in stock.

[0003] Taking the storage of SMT trays as an example, there is a Chinese utility model for an automatic sorting shelf for SMT trays, with the publication number: CN214651098U and the publication date: November 9, 2021. It discloses an automatic sorting shelf for SMT trays, which relates to the technical field of SMT tray storage. The utility model includes a shelf body, an XY linear motion module and a sorting mechanism. The front of the shelf body is provided with a tray storage position built by angle iron brackets. The tray storage position includes a tray storage area and a tray transfer area, and the tray transfer area is the leftmost column of the tray storage position. An XY linear motion module is fixedly connected to the shelf body behind the tray storage position, and a sorting mechanism is installed on the XY linear motion module. The sorting mechanism includes a base assembly, a picking and placing assembly and a tray turnover rack. The picking and placing assembly is fixedly connected to the top of one side of the base assembly through the top of an electric rotating table.

[0004] The disadvantages of this shelf when storing SMT trays are as follows: This shelf can only be expanded along the X-axis direction or the Z-axis direction, and it is difficult to expand along the Y-axis direction; because if this shelf is expanded along the Y-axis direction, it will cause the picking and placing assembly to be unable to grasp the trays after expansion along the Y-axis direction.

[0051] The terms used in the implementation manners part of the present application are only used to explain the specific embodiments of the present application, rather than aiming to limit the present application. The implementation manners of the embodiments of the present application will be described in detail below with reference to the drawings.

[0052] In one embodiment of the present application, such as Figures 1 to 3As shown, an expandable intelligent material storage device includes a tray storage unit 1, a transportation and sorting mechanism 2, and a tray inlet and outlet conveying mechanism 3. The tray storage unit 1 includes a storage rack 11 and multiple layers of storage drawers 12 arranged within the storage rack 11. The multiple layers of storage drawers 12 can be arranged in one column or multiple columns. In this embodiment, two columns are provided. A slide rail 13 is provided on the side of the storage rack 11. The transportation and sorting mechanism 2 is installed on the slide rail 13. The tray inlet and outlet conveying mechanism 3 is arranged at one end of the tray storage unit 1. The tray inlet and outlet conveying mechanism 3 is used to convey the stacked trays to the loading position of the transportation and sorting mechanism 2. The transportation and sorting mechanism 2 is used to transfer the stacked trays at the loading position to the storage drawer 12 of the tray storage unit 1. The transportation and sorting mechanism 2 first pulls out the storage drawer 12 of the tray storage unit 1, then transfers the tray to the storage drawer 12, and finally pushes the storage drawer 12 into the storage rack 11.

[0053] During the operation of this embodiment, first, the tray inlet and outlet conveying mechanism 3 conveys the stacked trays to the loading position of the transportation and sorting mechanism 2. Then, the transportation and sorting mechanism 2 moves along the slide rail 13 to the loading position. Next, the transportation and sorting mechanism 2 forks and transfers the stacked trays at the loading position to the designated storage drawer 12. Then, the transportation and sorting mechanism 2 first pulls out the storage drawer 12 of the tray storage unit 1, then transfers the tray to the storage drawer 12, and finally pushes the storage drawer 12 into the storage rack 11, thus completing the loading of the tray. When it is necessary to unload the tray, similarly, the transportation and sorting mechanism 2 first pulls out the storage drawer 12 of the tray storage unit 1, then transfers the tray in the storage drawer 12 to the transfer storage part of the transportation and sorting mechanism 2, and finally pushes the storage drawer 12 into the storage rack 11, thus completing the unloading of the tray.

[0054] As Figure 4 and Figure 5 shown, the tray storage unit 1 of this embodiment can be horizontally expanded, vertically expanded, or longitudinally expanded according to the site. Among them, for horizontal expansion, multiple tray storage units 1 can be spliced together. When vertical expansion is required, the number of layers of the storage drawers 12 can be increased or multiple tray storage units 1 can be stacked. And when this application conducts longitudinal expansion, the width dimensions of the tray storage unit 1 and the storage drawers 12 can be widened. Compared with the prior art, in the same space, this application can greatly increase the storage quantity of trays.

[0055] In addition, a slide rail 13 is provided on the side of the storage rack 11 in this embodiment. The transportation and sorting mechanism 2 is installed on the slide rail 13, so that there is no need to set a ground rail on the bottom surface to drive the movement of the transportation and sorting mechanism 2. In this embodiment, the slide rail 13 is provided on the side of the storage rack 11. When it is necessary to expand the tray storage unit 1, only multiple storage racks 11 need to be spliced together, so that the slide rails 13 on the storage racks 11 are docked together, and the assembly of the slide rail 13 can be completed. This can reduce the time for laying the ground rail and improve the assembly efficiency of the tray storage unit 1.

[0056] As Figure 8 shown, the storage drawer 12 in this embodiment includes a drawer frame 121 and multiple pallet boards 122. Bending parts 123 are respectively arranged at both ends of the pallet board 122, and the pallet board 122 is hung on the drawer frame 121 through the bending parts 123; multiple positioning columns are arranged on the pallet board 122. The pallet is supported by multiple pallet boards 122 hung on the drawer frame 121. First, the weight of the entire storage drawer 12 can be reduced, because the distance of the clearance position can be set according to the size of the tray between two pallet boards 122, so that the entire storage drawer 12 can store trays of different sizes. In addition, the tray is fixed by setting positioning columns, so that the storage drawer 12 can be prevented from moving when it moves.

[0057] In addition, the height of the drawer frame 121 in this embodiment can also be set according to the number of layers of trays to be stored, so that multiple layers of trays can be stored in one storage drawer 12, and the storage capacity of the trays is also improved.

[0058] As Figure 6 and Figure 7 shown, the transportation and sorting mechanism 2 in this embodiment includes a shuttle car 21 and a stacking mechanism 22. The shuttle car 21 is installed on the slide rail 13, and the stacking mechanism 22 is installed on the shuttle car 21. The shuttle car 21 can drive the stacking mechanism 22 to move horizontally along the slide rail 13, and the shuttle car 21 can drive the stacking mechanism 22 to make a lifting movement.

[0059] As Figure 6 and Figure 7 shown, the shuttle car 21 includes a shuttle frame 211, a lateral movement driving device 212 and a lifting driving device 213. The lateral movement driving device 212 is arranged on the shuttle frame 211 and cooperates with the slide rail 13 to drive the shuttle frame 211 and the stacking mechanism 22 to make a lateral movement. The lifting driving device is arranged on the shuttle frame 211 to drive the stacking mechanism 22 to make a lifting movement.

[0060] As Figure 6 and Figure 7A guiding device is provided on the upper side of the shuttle rack 211 shown. The guiding device is used to guide the shuttle rack 211. The guiding device includes a guiding wheel 214 and a guiding part 215. The guiding wheel 214 is arranged on the top of the shuttle rack 211, and the guiding part 215 is arranged on the front side of the storage rack 11. The top of the shuttle rack 211 is installed in the guiding part 215 of the storage rack 11 through the guiding wheel 214. The guiding wheel 214 and the guiding part 215 are provided to facilitate the installation of the shuttle rack 211. Since the lower side of the shuttle rack 211 needs to be installed in cooperation with the slide rail 13, the upper part thereof is provided with the guiding wheel 214 and the guiding part 215 to facilitate the adjustment of the cooperation between the shuttle rack 211 and the storage rack 11.

[0061] The transverse movement driving device 212 can be a linear motor, a gear-rack transmission device, a lead screw transmission device, a belt-gear transmission device, a cylinder transmission device, etc. The embodiments of the present application do not limit this, nor are they limited to the above examples.

[0062] The lifting driving device can be a linear motor, a gear-rack transmission device, a lead screw transmission device, a cylinder transmission device, etc. The embodiments of the present application do not limit this, nor are they limited to the above examples.

[0063] As Figure 8 and Figure 9 shown, the stacking mechanism 22 includes a mounting cross beam 221, a drawer pushing and pulling mechanism 222, a sorting manipulator 223, and a material taking and transferring mechanism 224. The drawer pushing and pulling mechanism 222, the sorting manipulator 223, and the material taking and transferring mechanism 224 are all installed on the mounting cross beam 221. The drawer pushing and pulling mechanism 222 is used to pull out or push in the storage drawer 12. The material taking and transferring mechanism 224 is used to temporarily store and transport the trays stacked on the upper layer of the conveying mechanism 3. The sorting manipulator 223 is used to transport the trays from the material taking and transferring mechanism 224 to the storage drawer 12 or from the storage drawer 12 to the material taking and transferring mechanism 224.

[0064] The sorting manipulator 223 can also be an XYZ-axis platform mechanism, a multi-axis robotic arm, or a three-axis or four-axis palletizing robotic arm. The embodiments of the present application do not limit this, nor are they limited to the above examples.

[0065] As Figure 8 and Figure 9As shown, the drawer push-pull mechanism 222 includes a material pushing drive device 2221, a mounting base 2222, and an electromagnet 2223. The electromagnet 2223 is disposed at least on one side of the mounting base 2222. The material pushing drive device 2221 is disposed on one side of the mounting cross beam 221 and is used to drive the mounting base 2222 and the electromagnet 2223 to move longitudinally. In this embodiment, the electromagnet 2223 is provided. When the electromagnet 2223 is powered on, its magnetism is activated and it adsorbs to the side surface of the drawer frame 121. When the electromagnet 2223 is powered off, its magnetism disappears and it does not adsorb to the side surface of the drawer frame 121. This application uses the magnetic adsorption method to push and pull the drawer-type tray, which not only has high efficiency but also has a simple structure. In addition, this application uses a suction cup device to suck the tray, which reduces the clamping time compared with the prior art and greatly improves the efficiency of taking and placing the tray.

[0066] The electromagnet can also be replaced by a clamping method using a cylinder or an electric cylinder. The embodiments of this application do not limit this and are not limited to the above examples.

[0067] As Figure 8 and Figure 9 As shown, in addition, when the tray storage unit 1 is set to two rows in this embodiment, the electromagnets 2223 in this embodiment can also be respectively disposed on both sides of the mounting base 2222, so as to correspond to the storage drawers 12 of the two rows of tray storage units 1, which can simplify the structure of the drawer push-pull mechanism 222.

[0068] As Figure 8 and Figure 9 As shown, in addition, two electromagnets 2223 can be respectively disposed on one side of the mounting base 2222. An active top block 2224 and a spring (not shown in the figure) are also disposed between the two electromagnets 2223. One end of the spring abuts against the mounting base 2222, and the other end abuts against the active top block 2224. When the electromagnet 2223 approaches the side of the drawer frame 121, since the active top block 2224 is longer than the electromagnet 2223, the active top block 2224 contacts the drawer frame 121 first, and then the active top block 2224 compresses the spring until the electromagnet 2223 is completely in electromagnetic adsorption with the drawer frame 121 and fixed. Therefore, the active top block 2224 and the spring play a buffering role. When the electromagnet is separated from the drawer frame 121, it can maintain the pressure for a certain distance to prevent the electromagnet 2223 from having residual magnetism to pull the drawer outwards.

[0069] As Figure 8 and Figure 9 As shown, in this embodiment, extension plates 2225 extend forward respectively on the upper and lower sides of the mounting base 2222 where the electromagnet 2223 is located. The distance between the upper and lower extension plates 2225 is slightly longer than the front height of the drawer frame 121, so as to facilitate clamping the drawer frame 121 and positioning the drawer frame 121.

[0070] AsFigure 10 , Figure 11 , Figure 12 As shown in Figure 12 , in this embodiment, the material taking and transfer mechanism 224 includes a mounting frame 2241, a first fork part 2242 and a second fork part 2243. The first fork part 2242 and the second fork part 2243 are both arranged on the mounting frame 2241, and the second fork part 2243 is located above the first fork part 2242.

[0071] Such as Figure 10 , Figure 11 , Figure 12 As shown in Figure 12 , the first fork part 2242 is respectively arranged on both sides of the mounting frame 2241. The first fork part 2242 includes a first fork plate 2241a, and a vacuum adsorption device 2241b is arranged on the first fork plate. Before the stacked trays are lifted by the first fork plate 2241a through the jig frame 2244, the first fork plate 2241a can firmly adsorb the bottom of the jig frame 2244 through the vacuum adsorption device 2241b, which can prevent the stacked trays from falling when the first fork plate 2241a moves.

[0072] In this embodiment, it can not only be a vacuum adsorption device, but also be clamped and fixed by a cylinder / electric cylinder. The embodiments of the present application do not limit this, nor are they limited to the above examples.

[0073] Such as Figure 10 , Figure 11 , Figure 12 As shown in Figure 12 , the vacuum adsorption device 2241b uses the vacuum pressure generated by the vacuum generating device as the power source, and the vacuum chuck adsorbs and grabs the bottom of the jig frame 2244, so as to achieve the purpose of moving the tray.

[0074] Such as Figure 10 , Figure 11 , Figure 12 As shown in Figure 12 , the second fork part 2243 includes a second fork plate 2243a and a fork plate lifting drive device 2243b. The fork plate lifting drive device 2243b is arranged in the mounting frame 2241. The second fork plates 2243a are respectively arranged on both sides of the fork plate lifting drive device 2243b, and the fork plate lifting drive device 2243b can drive the second fork plate 2243a to move up and down.

[0075] Such as Figure 10 , Figure 11 , Figure 12As shown, a U-shaped clearance 2243c is provided on one side of the second fork plate 2243a. The U-shaped clearance is provided to facilitate the cooperation between the second fork plate 2243a and the jig frame 2244. The jig frame 2244 for stacking trays includes a chassis 2244a and a string rod 2244b. A limiting step 2244c is provided on the upper surface of the chassis 2244a. The string rod 2244b is vertically installed for limiting adjustment. When the tray passes through the string rod 2244b and is sleeved on the chassis 2244a, the limiting step 2244c can create a distance between the chassis 2244a and the tray for the second fork plate 2243a to enter, so as to facilitate the second fork plate 2243a to extend into the bottom of the tray, thereby lifting the tray upward along the string rod 2244b. After the topmost tray is taken away, the remaining trays are lifted as a whole to ensure that the sorting manipulator 223 picks up materials at a fixed highest position.

[0076] In addition, the material taking and transfer mechanism 224 can also be installed on the installation cross beam 221 through a third lifting drive device (not shown in the figure), so that the material taking and transfer mechanism 224 can also move up and down on the stacking mechanism 22 to avoid the action blind area at the bottom of the equipment and improve the utilization rate of the bottom of the equipment. For example, when the stacking mechanism 22 drives the material taking and transfer mechanism 224 to descend to the lowest point, there is still room for the drawer pushing and pulling mechanism 222 and the sorting manipulator 223 to continue descending. However, since the trays need to be stored on the material taking and transfer mechanism 224, the bottom of the material taking and transfer mechanism 224 needs to be lower than the drawer pushing and pulling mechanism 222 and the sorting manipulator 223. Therefore, if the drawer pushing and pulling mechanism 222 and the sorting manipulator 223 are to continue descending, it is necessary to first lift the material taking and transfer mechanism 224 by the third lifting drive device and then lower the drawer pushing and pulling mechanism 222 and the sorting manipulator 223 to work. In this way, a storage drawer 12 can also be provided at the bottom of the entire equipment, which greatly increases the storage quantity of the equipment.

[0077] As Figure 13 shown, the tray in and out conveying mechanism 3 is a step belt conveyor line. The tray in and out conveying mechanism 3 can be set in multiple layers (1 layer, 2 layers, 3 layers, etc.) according to the site height and usage requirements. The multiple-layer tray in and out conveying mechanism 3 forms multiple in and out material channels, and the entire warehousing equipment can parallelly complete multiple logistics tasks with the external (AGV, assembly line, overhead rail, etc.).

[0078] As Figure 13 shown, the tray in and out conveying mechanism 3 can transport single trays or multiple stacked trays, and the transportation and sorting mechanism 2 on the shuttle car 21 can directly take away single trays or multiple stacked trays from the conveyor.

[0079] A suction cup device 4 is further provided at the material taking end of the sorting manipulator 223. When taking materials from SMT trays, since SMT trays have a variety of different specifications.

[0080] As shown Figure 14 in the figure, there are two different specifications of the SMT tray Q. Figure 1 In the SMT tray, there are four clearance holes, which are symmetrically arranged left and right. In addition, there is also an installation hole in the middle of the tray. Figure 2 In the SMT tray Q, there are three clearance holes, which are arranged in a circular array. In addition, there is also an installation hole in the middle of the tray. This causes the suction cups located on the clearance holes to be in the suction state all the time when the upper surface of the tray is sucked by an ordinary suction cup, resulting in energy waste.

[0081] As shown Figure 15 in the figure is the bottom view of the SMT tray suction cup device. Figure 4 is the cross-sectional view at A-A in Figure 3 . When the SMT tray suction cup device is in use, it is installed on a manipulator (not shown in the figure) or a linear slide rail 13 (not shown in the figure), and the SMT tray suction cup device is driven by the manipulator or the linear slide rail 13 to move downward to suck the surface of the SMT tray, and then move to the designated position.

[0082] As shown Figure 16 in the figure are the schematic diagrams of the SMT tray suction cup device before and after descending to pick up the material. In this embodiment, the SMT tray suction cup device includes a suction cup body 4 and an air valve a. The suction cup body 4 has an inner cavity 41 that can form a vacuum state, a first air extraction hole 42, and at least one second air extraction hole 43. The first air extraction hole 42 is connected to an air extraction pump (not shown in the figure) through an air extraction pipe 44. After the air extraction pump is started, the inner cavity 41 is evacuated, so that the inner cavity 41 forms a vacuum state. The first air extraction hole 42 is communicated with the inner cavity 41. In this embodiment, by setting the air valve a, the air valve a is arranged in each second air extraction hole 43, and when the SMT tray suction cup device descends, the height direction H of the air valve a in the second air extraction hole 43 is adjusted, that is, the position of the air valve a in the second air extraction hole 43 is adjusted to close or conduct the communication between the second air extraction hole 43 and the inner cavity 41. If the second air extraction hole 43 is communicated with the inner cavity 41, the second air extraction hole 43 can adsorb the surface of the SMT tray. If the second air extraction hole 43 is not communicated with the inner cavity 41, the second air extraction hole 43 at this place cannot adsorb the surface of the SMT tray Q.

[0083] As shown Figure 16As shown, when the suction cup device of the present application sucks the SMT tray downward, before the air valve a abuts against the SMT tray, the air valve a is in a state of closing the communication between the second air extraction hole 43 and the inner cavity 41. When the air valve a abuts against the upper surface of the SMT tray, the air valve a moves upward, resulting in a change in the height of the air valve a at the second air extraction hole 43, thereby connecting the second air extraction hole 43 and the inner cavity 41. The first air extraction hole 42 continuously extracts the air in the inner cavity 41 and the second air extraction hole 43 communicating with the inner cavity 41, so that a negative pressure is formed on the contact surface between the second air extraction hole 43 and the tray. If the air valve a is located in the avoidance hole of the SMT tray, the air valve a does not move, and the height of the air valve a at the second air extraction hole 43 does not change, then the air valve a closes the communication between the second air extraction hole 43 and the inner cavity 41, thus not affecting the operation of the second air extraction hole 43 communicating with the inner cavity 41. Therefore, the present application can suck SMT trays of different specifications, that is, the positions or sizes of the avoidance holes on the upper surface of the tray are different, and it will not affect the material taking of the present application.

[0084] A preferred embodiment of the air valve a of the present application is that the air valve a includes a needle valve a1 and an elastic member a2. One end of the elastic member a2 is installed on the side wall of the inner cavity 41, and the other end of the elastic member a2 is installed on the upper end of the needle valve a1. The middle part of the needle valve a1 is in sealing cooperation with the second air extraction hole 13. The elastic member a2 is used to drive the end face of the needle valve a1 to extend out of the bottom surface of the suction cup body 4 downward and close the communication between the second air extraction hole 43 and the inner cavity 41. When an external force drives the needle valve a1 to move upward to compress the elastic member a2 and makes the end face of the needle valve a1 retract upward into the bottom surface of the suction cup body 4, the second air extraction hole 43 is communicated with the inner cavity 41.

[0085] Another preferred embodiment of the air valve a of the present application is that the air valve a is an electric air valve a or a pneumatic air valve a, and the communication or closing of the second air extraction hole 43 can also be controlled separately.

[0086] The elastic member a2 is a spring or a spring sheet or an elastic plastic block or other elastic members made of elastic materials.

[0087] A preferred embodiment one of the needle valve of the present application is as Figure 17 As shown, the lower part of the needle valve a1 is conical. When the conical surface a3 of the lower part of the needle valve a1 enters the inner cavity 41, a gap a4 is formed between the conical surface a3 and the second air extraction hole 43, and air can enter the inner cavity 41 from the gap, thereby making the second air extraction hole 43 communicate with the inner cavity 41.

[0088] A preferred embodiment two of the needle valve of the present application is as Figure 18As shown, there is a ventilation groove b2 provided at the lower part of the needle valve b1. When the needle valve b1 moves upward such that the ventilation groove extends into the inner cavity 41, the second air extraction hole 43 communicates with the inner cavity 41. As a result, the second air extraction hole 43 can quickly extract the air on the upper surface of the SMT tray to form a negative pressure state, enabling the second air extraction hole 43 at this location to adsorb the surface of the SMT tray.

[0089] The third preferred embodiment of the needle valve of the present application is as Figure 19 As shown, a hollow ventilation channel c2 is formed by opening upward at the bottom of the needle valve c1. A ventilation hole c3 is provided on the side of the needle valve c1. One end of the ventilation hole c3 communicates with the ventilation channel c2, and the other end of the ventilation hole c3 penetrates the surface c4 of the needle valve c1.

[0090] In a possible implementation manner, as Figure 21 shown in the enlarged view F, in order to improve the adsorption strength, a suction cup cover 422 is provided at the lower port of the second air extraction hole 43. The provision of the suction cup cover 422 can increase the adsorption area between the suction cup device and the SMT tray being sucked.

[0091] In a possible implementation manner, as Figure 20 shown in the enlarged view E, in order to prevent scratching or damaging the tray, the lower surface of the suction cup body 4 is the adsorption surface 45, and a first buffer layer 46 is provided on the adsorption surface 45.

[0092] In a possible implementation manner, as Figure 20 shown in the enlarged view E, in order to prevent scratching or damaging the tray, in another embodiment of the present application, a second buffer layer a5 is provided on the end face of the needle valve a1.

[0093] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, or an indirect connection through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.
