Description

Technical Field

[0001] This invention relates to the field of sheet metal parts storage and retrieval devices, and more specifically to a modular sheet metal parts storage and retrieval device and storage unit. Background Technology

[0002] Sheet metal parts are workpieces made from thin metal sheets through a comprehensive cold working process. Sheet metal parts vary in length and structure, and racks are often used to store and store them.

[0003] According to publication number CN218988021U, publication date: May 9, 2023, a device for storing and retrieving parts on a large automotive sheet metal parts bin is disclosed. This device includes a mounting plate and upright plates mounted on both sides of the upper end of the mounting plate. Several linkage units are movably connected between the two upright plates. Each linkage unit includes a movable mounting plate. One side of every two adjacent movable mounting plates is movably connected to a connecting unit attached to the outside of one of the upright plates. Furthermore, one end of each movable mounting plate extends through the upright plate to the outside and abuts against the workpiece. This invention has a simple structure and is easy to operate. It achieves automated guidance for bin docking, making the storage and retrieval mechanism more convenient to operate, thereby effectively improving work efficiency. Moreover, the multiple linkage units are a flexible system assembly, making parts less prone to damage and significantly reducing production costs.

[0004] In the prior art, including the aforementioned patent, sheet metal parts are placed on movable platforms, and multiple movable platforms are driven by connecting rods to load the workpiece onto the upper movable platform for easy removal of the sheet metal parts. However, when the sheet metal parts need to be transferred and stored, manual operation is still required to remove the sheet metal parts from the movable platforms and place them on a trolley for transfer. Subsequently, the sheet metal parts are moved and placed in the required position. The manual handling of the sheet metal parts still requires manpower and is also accompanied by the risk of the sheet metal parts falling during handling. Summary of the Invention

[0005] The purpose of this invention is to provide a modular storage and retrieval device and storage unit for sheet metal parts, in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a modular storage and retrieval device and storage unit for sheet metal parts, comprising:

[0007] A base frame is provided, on which several loading slots are provided for the movable installation of several pallet assemblies;

[0008] A transfer frame with transfer wheels at its bottom is fitted to a base frame so that the transfer frame and the pallet assembly are combined into one unit.

[0009] Wherein: the pallet assembly includes a pallet body, and a bearing seat that moves relatively horizontally is provided inside the pallet body. In the default state, the bearing seat makes the first flexible support member fixedly connected to it in a straight line. The transfer frame is driven to combine with the pallet assembly to drive the bearing seats to move closer to each other, and makes the first flexible support member concave in the middle.

[0010] Preferably, the device also includes a locking assembly comprising a locking frame slidably disposed vertically on a placement base, the locking frame being driven to slide such that an abutment disposed thereon vertically abuts against the tray body to lock it in place.

[0011] Preferably, the pallet body is rotatably provided with a support roller located between the horizontal bearing seats. The support roller is provided with an extended foot in a circumferential array so that the cross-section of the support roller is herringbone-shaped. The rotation axis of the support roller is vertically aligned with the middle of the first flexible support member. The bearing seat is driven to move horizontally closer to clamp and lock on both sides of the support roller.

[0012] Preferably, the support base is provided with a first magnetic element and a second magnetic element with opposite magnetic properties, the extension foot is provided with a U-shaped electromagnetic rod, the tray body is provided with an electrode plate, and the support wheel is in a V-shape by default so that the end of the electromagnetic rod on the extension foot at the highest point contacts the electrode plate. The support wheel is driven to rotate by the magnetic drive of the first magnetic element and the second magnetic element, so that multiple electromagnetic rods contact and separate from the electrode plate.

[0013] Preferably, it also includes a flip seat that is horizontal in the default state. The support seat is slidably disposed on the flip seat to maintain horizontal movement. The locking frame is provided with a second elastic element so that the abutment can maintain vertical movement. After the locking frame is driven to slide vertically to lock the tray body, the locking frame continues to slide to abut and flip the flip seat. The support seat follows the flip seat to flip so that the first flexible support moves vertically to the top of the tray body.

[0014] Preferably, the first flexible support member has a filling cavity for filling iron powder, and the two ends of the filling cavity are respectively aligned with the first magnetic element and the second magnetic element on the support seat.

[0015] Preferably, the filling cavity has several lower grooves in the middle. The support wheel is driven by the magnetic drive to rotate, so that the electromagnetic rod attracts the iron powder in the filling cavity to form a clump and move through the lower grooves in sequence, so that the upper support surface of the first flexible support member moves in a wave-like undulation along the rotation direction of the electromagnetic rod.

[0016] Preferably, the system also includes a buffer assembly, which includes an arc-shaped slider that is slidably disposed at the end of the support seat and a third elastic element that drives the arc-shaped slider to slide out. The extended foot of the support wheel is symmetrically provided with abutment grooves, and the support seat is driven to slide closer so that the arc-shaped slider abuts against the abutment grooves to clamp it.

[0017] Preferably, the locking frame further includes a drive wheel and a transmission gear rotatably mounted on the base frame. The transmission gear meshes with a rack portion mounted on the locking frame, and the worm portion mounted on the drive wheel meshes with a worm wheel portion mounted on the transmission gear.

[0018] A storage repository includes the modular access device for sheet metal parts described in the above scheme.

[0019] In the above technical solution, the present invention provides a modular storage and retrieval device and storage unit for sheet metal parts, which has the following beneficial effects: by combining a tray assembly and a placement base frame into one unit to place the sheet metal parts to be stored, the transfer frame can be attached to the placement base frame to combine the tray assembly and the transfer frame into one unit. Then, by moving the transfer frame, the tray body and the sheet metal parts placed on it can be directly moved and transferred to the placement base frame in other positions, completing the rapid transfer of sheet metal parts. No additional manual operation is required to remove the sheet metal parts from the tray body, thereby simplifying the transfer process and improving the transfer efficiency. At the same time, it can avoid the risk of falling when manually removing sheet metal parts in the traditional method, improving the transfer safety. Secondly, the first flexible support member set on the bearing seat can sink to a certain extent to prevent accidental movement of the sheet metal parts and avoid the deformation of the sheet metal parts themselves. During the transfer process, the first flexible support member is concave in the middle to form an arc-shaped limiting groove to prevent the sheet metal parts from falling due to vibration during the transfer process.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0040] like Figure 1-16 As shown, a modular storage and retrieval device and storage unit for sheet metal parts includes:

[0041] A base frame 1 is provided, on which several loading slots 11 are provided for the movable installation of several pallet assemblies 2;

[0042] The transfer frame 3 has transfer wheels 32 at its bottom. The transfer frame 3 fits against the base frame 1 so that the transfer frame 3 and the pallet assembly 2 are combined into one unit.

[0043] Wherein: the pallet assembly 2 includes a pallet body 21, and a support seat 22 that moves relatively in the horizontal direction is provided inside the pallet body 21. In the default state, the first flexible support member 291 fixedly connected to the support seat 22 is in a straight line. The transfer frame 3 is driven to combine with the pallet assembly 2 to drive the support seat 22 to move closer to each other, and the first flexible support member 291 is concave in the middle.

[0044] Specifically, such as Figure 1 As shown, the base frame 1 is fixedly installed on the ground at the required location, such as... Figure 2As shown, the placement base 1 has several loading slots 11 arranged in a vertical linear array, and the pallet body 21 of the pallet assembly 2 has loading parts 211 on both sides. The pallet body 21 can be installed onto the placement base 1 through the loading parts 211, thereby combining the pallet assembly 2 and the placement base 1 into one unit to place the sheet metal parts to be stored. Figure 2 As shown, the bottom of the transfer frame 3 is equipped with a rolling transfer wheel 32, and the transfer frame 3 is equipped with multiple sets of interlocking columns 31. When the transfer frame 3 is in the following position... Figure 1 When attached to the placement base 1, the fitting post 31 fits into the embedding hole 212 on the pallet body 21, thereby combining the pallet assembly 2 with the transfer frame 3. At this time, the transfer frame 3 can be rolled out of the outside of the placement base 1 to take out the pallet body 21. By moving the transfer frame 3, the pallet body 21 and the sheet metal parts placed on it can be directly moved and transferred to other placement bases 1, thereby completing the rapid transfer of sheet metal parts. No additional manual operation is required to remove the sheet metal parts from the pallet body 21, thus simplifying the transfer process and improving transfer efficiency. At the same time, it can avoid the risk of dropping when manually removing sheet metal parts in the traditional method, improving the transfer safety. The pallet assembly 2 can be used as a storage module or a transfer module, thereby improving the usability of the pallet assembly 2.

[0045] Furthermore, such as Figure 5 As shown, a horizontally movable support seat 22 is provided inside the pallet body 21, and a first elastic member 26 is also provided inside the pallet body 21. The first elastic member 26 is used to drive the two support seats 22 to tighten the first flexible support member 291 on the support seats 22 in a straight line shape in the default state. That is, when the pallet body 21 is combined with the placement base 1 to store sheet metal parts, the first flexible support member 291 of the pallet body 21 serves as a support surface in a straight plane shape, which prevents the sheet metal parts from falling due to accidental movement. At the same time, the first flexible support member 291 can also sink to a certain extent to further prevent the sheet metal parts from moving accidentally. Moreover, by using the first flexible support member 291 to flexibly support the sheet metal parts, it can prevent the sheet metal parts from being pressed hard on the pallet body 21 and causing deformation of the sheet metal parts themselves, thus improving the protection of the sheet metal parts.

[0046] The first elastic element 26 can be replaced by other elastic elements known to those skilled in the art, such as springs, airbags, or elastic plates.

[0047] When the transfer frame 3 is attached to the placement base frame 1 for the transfer of the pallet body 21 and sheet metal parts, the fitting column 31 is fitted onto the pallet body 21 so that the pallet body 21 and the transfer frame 3 are combined into one unit. At this time, the bearing seat 22 overcomes the first elastic member 26 and slides closer to each other. At this time, the two ends of the first flexible support member 291 are no longer stretched, and the middle part is pressed down by the weight of the sheet metal parts and becomes concave in the middle, so as to form a concave arc-shaped limiting groove in the middle of the bearing surface of the pallet body 21. The sheet metal parts are located in the arc-shaped limiting groove to prevent the sheet metal parts from being vibrated and falling outside the pallet body 21 during the transfer process, thereby improving the safety of the sheet metal parts transfer.

[0048] Furthermore, such as Figure 16 As shown, a mating groove 221 is provided in the bearing seat 22, and the end of the fitting column 31 is beveled. When the fitting column 31 passes through the insertion hole 212 of the pallet body 21 and abuts against the mating groove 221, the fitting column 31 pushes the bearing seat 22 to slide closer, so that the first flexible support member 291 is concave in the middle. At this time, the reset elasticity of the first elastic member 26 makes the fitting column 31 and the mating groove 221 mutually lock together, thereby fixing the pallet body 21 and the transfer frame 3 together and improving the installation stability of the pallet body 21 on the transfer frame 3. A clamping ring is provided at the connection between the fitting column 31 and the transfer frame 3 to improve the structural strength of the fitting column 31.

[0049] Furthermore, such as Figure 5 and Figure 6 As shown, a second flexible support member 292 is also provided inside the pallet body 21. It is fixedly connected to both ends of the first flexible support member 291 and covers the remaining inner support surface of the pallet body 21, so that the inner support surface of the pallet body 21 has the function of flexibly supporting sheet metal parts. The second flexible support member 292 follows the deformation and reverse deformation of the first flexible support member 291.

[0050] In the above technical solution, the pallet assembly 2 and the placement base 1 are combined into one unit to place the sheet metal parts to be stored. The transfer frame 3 can be attached to the placement base 1 to combine the pallet assembly 2 and the transfer frame 3 into one unit. Then, by moving the transfer frame 3, the pallet body 21 and the sheet metal parts placed on it can be directly moved and transferred to the placement base 1 in other positions to complete the rapid transfer of sheet metal parts. There is no need for additional manual operation to remove the sheet metal parts from the pallet body 21, thereby simplifying the transfer process and improving the transfer efficiency. At the same time, it can avoid the risk of falling when manually removing sheet metal parts in the traditional method and improve the transfer safety. Secondly, the first flexible support 291 set on the bearing seat 22 can sink to a certain extent to prevent the sheet metal parts from moving accidentally and to avoid the deformation of the sheet metal parts themselves. During the transfer process, the first flexible support 291 is concave in the middle to form an arc-shaped limiting groove to prevent the sheet metal parts from falling due to vibration during the transfer process.

[0051] As another embodiment of the present invention, it also includes a locking component 4, which includes a locking frame 41 that is vertically slidably disposed on the placement base 1. The locking frame 41 is driven to slide so that the abutment 42 disposed thereon vertically abuts against the tray body 21 to lock it.

[0052] Specifically, such as Figure 1 As shown, the locking frame 41 is provided with a sliding part 411, and the sliding part 411 is provided with an abutment 42. The locking frame 41 is vertically slidably mounted on the placement base frame 1 through the sliding part 411. When the locking frame 41 slides vertically upward, the sliding part 411 drives the abutment 42 to move vertically upward to abut against the loading part 211 of the pallet body 21, thereby fixing and locking the pallet body 21 on the placement base frame 1, thereby increasing the placement stability of the pallet body 21. When the pallet body 21 is installed on the placement base frame 1 to store sheet metal parts, the pallet body 21 can be locked by the locking frame 41. When it is necessary to transfer the pallet body and the sheet metal parts on it, the pallet body 21 is unlocked by sliding the locking frame 41 in the opposite direction. Then the pallet body 21 and the transfer frame 3 are combined into one unit for the transfer process.

[0053] The locking frame 41 can be driven to slide by a drive cylinder, or it can be pushed to slide by a multi-link linkage, or it can be replaced by other driving methods known to those skilled in the art.

[0054] As another embodiment of the present invention, a support wheel 23 is rotatably disposed inside the pallet body 21 and located between the horizontal directions of the support seat 22. The support wheel 23 is provided with an extended foot 231 arranged in a circumferential array so that the cross-section of the support wheel 23 is herringbone-shaped, and the rotation axis of the support wheel 23 is vertically aligned with the middle of the first flexible support member 291. The support seat 22 is driven to move horizontally closer to clamp and lock on both sides of the support wheel 23.

[0055] Specifically, such as Figure 5 As shown, the support roller 23 is provided with an extension foot 231 so that the cross-section of the support roller 23 is in the shape of a herringbone. The support roller 23 is located between two support seats 22, so that the support seats 22 move closer or further away from the support roller 23 in sync when moving. Due to the influence of gravity, the support roller 23 is in the shape of an upright herringbone in its default state. When the tray body 21 and the placement base 1 are combined into one unit to store small sheet metal parts, the small sheet metal parts will be placed in the middle of the first flexible support member 291 so that the first flexible support member 291 is concave, thereby pushing the extension foot 231 of the support roller 23, so that the support roller 23 rotates to an inverted herringbone shape. At this time, the middle of the first flexible support member 291 is supported by the two extension feet 231 of the support roller 23, thereby improving the support stability of the small sheet metal parts, and also preventing the first flexible support member 291 from being damaged due to excessive pressure.

[0056] When the pallet body 21 and the transfer frame 3 are combined into one unit, the two bearing seats 22 are driven to move closer together to clamp the two sides of the support wheel 23, so that the support wheel 23 is clamped and locked in an inverted V-shape. Therefore, during the transfer process, the first flexible support member 291 is concave in the middle, and the concave middle of the first flexible support member 291 is supported by the extension foot 231 of the support wheel 23, so as to avoid the problem that the small sheet metal parts placed on the first flexible support member 291 will shake and fall off due to the elastic up and down shaking of the middle part during the transfer process, thereby further improving the support stability of the first flexible support member 291.

[0057] As another embodiment of the present invention, the support base 22 is provided with a first magnetic element 51 and a second magnetic element 52 with opposite magnetic properties, the extension foot 231 is provided with a U-shaped electromagnetic rod 53, the tray body 21 is provided with an electrode plate 213, and the support roller 23 is in a V-shape in the default state so that the end of the electromagnetic rod 53 on the extension foot 231 at the highest point contacts the electrode plate 213. The support roller 23 is driven to rotate by the magnetic drive of the first magnetic element 51 and the second magnetic element 52, so that the multiple electromagnetic rods 53 contact and separate from the electrode plate 213.

[0058] Specifically, such as Figure 5 As shown, a first magnetic element 51 and a second magnetic element 52 are respectively provided on the two support seats 22, and as... Figure 8 As shown, a U-shaped electromagnetic rod 53 is provided on the support roller 23, with both ends of the electromagnetic rod 53 facing the electrode plate 213 provided on the tray body 21. Figure 10 As shown, electrode 213 is located at the highest point of the support roller 23 when it is in a V-shape. When the support roller 23 is driven by gravity to rotate to the default state where the cross-section is upright in a V-shape, electrode 213 can be continuously energized. At this time, electrode 213 energizes the electromagnetic rod 53 to generate magnetic poles on the electromagnetic rod 53. Since the support base 22 is provided with a first magnetic element 51 and a second magnetic element 52 with opposite magnetic properties, the mutual attraction and repulsion of the magnetic poles will cause the support roller 23 to rotate under the action of magnetism. After the support roller 23 rotates, it reaches its highest point. The electromagnetic rod 53 separates from the electrode plate 213, causing the magnetism of the electromagnetic rod 53 to gradually disappear. As the support roller 23 rotates, another set of electromagnetic rods 53 comes into contact with the electrode plate 213 and generates magnetism, causing the support roller 23 to rotate again under magnetism. Thus, the electromagnetic rod 53, the first magnetic element 51, and the second magnetic element 52 are used to enable the support roller 23 to rotate continuously. The first magnetic element 51 and the second magnetic element 52 should be provided at the end of the support seat 22 near the support roller 23 to increase the rotational driving force of the support roller 23.

[0059] When the transfer frame 3 is not attached to the placement base frame 1, and the pallet column 21 is directly installed on the placement base frame 1, the bearing seat 22 is relatively far away, allowing the support roller 23 to rotate. If the electrode plate 213 is energized, the electromagnetic rod 53 is energized and generates magnetism, which in turn drives the support roller 23 to rotate. Subsequently, the electromagnetic rod 53 moves and is de-energized again, and then energized again as the support roller 23 rotates, repeating the cycle to achieve continuous rotation of the support roller 23. The extension leg 23 of the support roller 23... An inclined air guide surface 2311 is provided on the pallet body 21, and an outlet hole 214 is provided on the pallet body 21. The rotation of the support roller 23 ventilates the pallet body 21 through the rotation of the inclined air guide surface 2311, thus avoiding the problem of dust and moisture accumulation on the sheet metal parts. Secondly, the support roller 23 has angular momentum due to rotation, which makes the support roller 23 located inside the pallet body 21 and act like a gyroscope, increasing the fixed stability of the pallet body 21 and preventing the pallet body 21 from tipping over.

[0060] When the transfer frame 3 is placed against the base frame 1 so that the fitting column 31 fits into the pallet body 21, and the pallet body 21 is placed on a sheet metal part with a large contact area, the middle part of the first flexible support member 291 is not easy to sink due to the large contact area. The cross-section of the support roller 23 is upright in a V-shape. The bearing seat 22 is relatively close to clamp the two sides of the support roller 23. At this time, the electrode plate 213 performs an action on the electromagnetic rod 53. The electromagnetic rod 53 forms two unclosed magnetic lines of force between the first magnetic member 51 and the second magnetic member 52. Then, when the sheet metal with a large contact area is placed on the first flexible support member 291, the electromagnetic rod 53 and the first magnetic member 51 and the second magnetic member 52 set on the support roller 23 and the bearing seat 22 form a similar magnetic attraction fixing component, thereby adsorbing and fixing the large sheet metal part to the pallet body 21, avoiding the problem of the large sheet metal part accidentally moving and causing tipping damage during the transfer process. Secondly, the first flexible support 291 is pressed down by the large sheet metal part and recesses between the support roller 23 and the bearing seat 22, thereby forming two non-contact grooves between the first flexible support 291 and the placement surface of the large sheet metal part. This avoids the problem of the sheet metal part being difficult to remove due to prolonged adhesion between the placement contact surface of the large sheet metal part and the first flexible support 291.

[0061] The tray body 21 may contain a battery and a switch that are electrically connected to the electrode plate 213. This is common knowledge to those skilled in the art and will not be described in detail here.

[0062] As another embodiment of the present invention, it also includes a flip seat 25 that is horizontal in the default state. The support seat 22 is slidably disposed on the flip seat 25 to maintain horizontal movement. The locking frame 41 is provided with a second elastic member 43 so that the abutment member 42 can maintain vertical movement. After the locking frame 41 is driven to slide vertically to lock the tray body 21, the locking frame 41 continues to slide to abut and flip the flip seat 25. The support seat 22 follows the flip seat 25 to flip so that the first flexible support member 291 moves vertically to the top of the tray body 21.

[0063] Specifically, such as Figure 5 As shown, the tilting seat 25 is rotatably disposed within the pallet body 21, while the support seat 22 is slidably disposed within the tilting seat 25 for horizontal movement. The pallet body 21 is provided with an elastic element for keeping the tilting seat 25 horizontal in its default state. Figure 4 As shown, a second elastic member 43 is provided in the sliding part 411 of the locking frame 41, and the abutment member 42 is slidably disposed on the sliding part 411. The second elastic member 43 drives the abutment member 42 to slide vertically on the outside of the sliding part 411.

[0064] like Figure 2 As shown, the flip seat 25 is provided with a mounting part 252. One end of the first elastic member 26 is fixedly connected to the mounting part 252, and the other end is fixedly connected to the support seat 22 to drive the support seat 22 to slide.

[0065] When the locking frame 41 is driven to slide vertically upward, the abutment 42 slides upward with the locking frame 41 to abut against the loading part 211 of the pallet body 21. As the locking frame 41 continues to move upward, the second elastic member 43 is compressed to increase the pressure of the abutment 42 against the loading part 211, thereby further improving the locking stability of the abutment 42 on the pallet body 21.

[0066] Furthermore, the locking frame 41 is provided with a crossbar 412, and the flipping seat 25 is provided with an extension post 251 extending out of the tray body 21. When the locking frame 41 is driven to move vertically upward so that the contact member 42 locks the tray body 21, the crossbar 412 also moves upward with the locking frame 41 to cover the front side of the tray body 21, thereby preventing the tray body 21 from sliding out laterally and further improving the installation stability of the tray body 21. If the locking frame 41 continues to move vertically upward, the crossbar 412 moves vertically upward to push the extension post 251, thereby causing the locking frame 41 to push against the flipping seat 25 and drive the bearing seat 22 to continue to flip. At this time, the end of the bearing seat 22 flips upward to drive the first flexible support member 291 on it to move upward to the top of the tray body 21, thereby raising the sheet metal parts placed on the first flexible support member 291 to the outside of the tray body 21, thereby realizing that while the tray body 21 is locked and fixed, the sheet metal parts can be easily taken out and used.

[0067] The second elastic element 43 can be replaced by other elastic elements known to those skilled in the art, such as springs, elastic plates, or airbags.

[0068] As another embodiment of the present invention, the first flexible support member 291 has a filling cavity 2911 for filling iron powder, and the two ends of the filling cavity 2911 are respectively aligned with the first magnetic member 51 and the second magnetic member 52 on the support seat 22.

[0069] Specifically, such as Figure 5 As shown, the first flexible support member 291 has a filling cavity 2911 for filling iron powder, and the two ends of the filling cavity 2911 are aligned with the first magnetic element 51 and the second magnetic element 52 on the two bearing seats 22, respectively. Since the two sides of the iron powder in the filling cavity 2911 are close to the first magnetic element 51 and the second magnetic element 52, the iron powder is driven by the first magnetic element 51 and the second magnetic element 52 to attract and connect with each other along the magnetic field lines, thereby making the iron powder in the first flexible support member 291 form a similar effect to a structural rope, thereby improving the load-bearing capacity of the first flexible support member 291.

[0070] Furthermore, vents and a shielding layer can be provided in the first flexible support 291. The shielding layer is used to prevent iron powder from leaking out of the first flexible support 291, so that the iron powder can dry the inside of the tray body 21, avoiding the problem of moisture corrosion of the sheet metal parts. The first flexible support 291 should be detachably fixed to the support seat 22 to facilitate the replacement of the first flexible support 291 and the iron powder inside it. The detachable fixing method of the first flexible support 291 to the support seat 22 is common technical knowledge to those skilled in the art and will not be described in detail here.

[0071] As another embodiment of the present invention, a plurality of lower grooves 2912 are provided in the middle of the filling cavity 2911. The support roller 23 is driven to rotate by the magnetic drive so that the electromagnetic rod 53 adsorbs the iron powder in the filling cavity 2911 and moves through the lower grooves 2912 in sequence, so that the upper support surface of the first flexible support member 291 moves in a wave-like undulating motion along the rotation direction of the electromagnetic rod 53.

[0072] Specifically, such as Figure 14 As shown, a plurality of lower grooves 2912 are provided in the filling cavity 2911 in the middle of the first flexible support 291. When the support seat 22 is in the default state so that the support roller 23 has room to rotate, if the electrode plate 213 is energized, the electromagnetic rod 53 at the high point is energized to adsorb the iron powder in the filling cavity 2911 and make it clump together.

[0073] When a large sheet metal part is placed on the pallet body 21, the first flexible support member 291 has a large contact area with the sheet metal part. Therefore, the central depression of the first flexible support member 291 is small, and it is almost horizontal, so that the distance between the filling cavity 2911 and the support roller 23 is large. At this time, the electromagnetic rod 53 generates electromagnetic properties to make the support roller 23 rotate. This causes the electromagnetic rod 53 at the high point to form an attraction force on the iron powder in the center of the first flexible support member 291 and drive the center of the first flexible support member 291 to be depressed by the attraction force. Then the support roller 23 continues to rotate to de-energize the electromagnetic rod 53. At this time, the first flexible support member 291... The middle part of the first flexible support 291 is reset upwards, and then the abutment roller 23 continues to rotate so that another set of electromagnetic rods 53 is energized to attract the middle part of the first flexible support 291 to sink again. Then, through the abutment roller 23, electromagnetic rods 53 and iron powder, the middle part of the first flexible support 291 is repeatedly vertically sinked and reset, so that the large sheet metal parts move to the center of the pallet body 21, thereby avoiding the problem of the pallet body 21 tipping over due to the tilt of the center of gravity of the large sheet metal parts. Secondly, it can also avoid the problem of the contact surface of the large sheet metal parts sticking to the first flexible support 291 due to long-term contact.

[0074] When a small sheet metal part is placed on the tray body 21, the central part of the first flexible support 291 is significantly concave, making the filling cavity 2911 closer to the support roller 23. Therefore, as the electromagnetic rod 53 rotates with the support roller 23, it will inevitably be moved due to magnetism, attracting iron powder from the filling cavity 2911. Figure 13 As shown, the filling cavity 2911 has several lower grooves 2912. When the support roller 23 is driven by magnetism to rotate clockwise, the extension foot 231 at the highest point rotates axially from left to right. The electromagnetic rod 53 on the extension foot 231 rotates to drive the adsorbed iron powder clumps in the filling cavity 2911 to move from left to right. The adsorbed iron powder clumps pass over the lower grooves 2912 in sequence. As the cross-sectional area of ​​the iron powder clumps changes back and forth in the movement path, the iron powder clumps will cause the upper surface of the first flexible support member 291 to form a wave-like upward protrusion due to the movement. Then, the small sheet metal parts are supported and rotated by the wave-like upward protrusion. First, it can prevent the small sheet metal parts from sticking to the first flexible support member 291. Second, it can also be flipped to change the placement surface of the small sheet metal parts, thereby avoiding the problem of bottom deformation caused by the small sheet metal parts being placed for a long time due to their own weight because the contact surface is too small.

[0075] The first flexible support 291 is filled with iron powder. The iron powder is wrapped by the flexible first flexible support 291. When a large sheet metal part is placed, the large sheet metal part can easily squeeze the iron powder to move closer to the first magnetic part 51 and the second magnetic part 52. Moreover, the iron powder is loose and it is difficult to form a Faraday isolation layer similar to an iron plate, so as not to interfere with the normal magnetic attraction and fixation of the large sheet metal part by the first magnetic part 51, the second magnetic part 52 and the electromagnetic rod 53.

[0076] As another embodiment of the present invention, it also includes a buffer assembly 6, which includes an arc-shaped slider 61 that is slidably disposed at the end of the support seat 22 and a third elastic member 62 that drives the arc-shaped slider 61 to slide out. The extension foot 231 of the support wheel 23 is symmetrically provided with abutment grooves 232. The support seat 22 is driven to slide closer so that the arc-shaped slider 61 abuts against the abutment grooves 232 to clamp it.

[0077] Specifically, such as Figure 13 As shown, symmetrical abutment grooves 232 are provided on the extension foot 231, and the arc-shaped slider 61 of the buffer assembly 6 is slidably disposed on the end of the support seat 22 near the abutment wheel 23. The arc-shaped slider 61 is driven by the third elastic member 62 to extend out of the outside of the support seat 22. When the transfer frame 3 and the pallet body 21 are combined into one for transfer, the support seat 22 moves relatively close to clamp the abutment wheel 23 to lock the abutment wheel 23, and is locked by the first magnetic member 51 and the second magnetic member 52. 2. The sheet metal parts are magnetically fixed to the electromagnetic rod 53. As the support seat 22 approaches, the end of the arc-shaped slider 61 gradually approaches and abuts against the abutment groove 232 of the abutment roller 23. Under the drive of the third elastic element 62, the arc-shaped slider 61 is clamped on both sides of the abutment roller 23. At this time, the arc-shaped slider 61 and the third elastic element 62 are used to avoid the support seat 22 directly clamping the abutment roller 23 and causing damage. The third elastic element 62 plays a buffering role. The third elastic element 62 can be replaced by springs, airbags, elastic plates, or other elastic elements known to those skilled in the art.

[0078] Secondly, when the pallet body 21 is transferred from the transfer frame 3 to another placement base 1, the pallet body 21 can be assembled onto the placement base 1, and the transfer frame 3 can be removed from the pallet body 21. At this time, as the transfer frame 3 is removed, the support seat 22 moves away from the abutment wheel 23. Due to the presence of the arc-shaped slider 61, when the support seat 22 has moved away from the abutment wheel 23 but there is still not enough space for the abutment wheel 23 to rotate between the support seats 22, the electromagnetic rod 53 at the high point of the abutment wheel 23 is energized. The abutment wheel 23 is pushed by the magnetic force to rotate clockwise and will then abut against the arc-shaped slider 61. Block 61 drives the arc-shaped slider 61 to retract, and at this time, after the support roller 23 rotates a certain angle, the electromagnetic rod 53 is de-energized due to separation from the electrode plate 213. Therefore, under the force of gravity and the thrust of the arc-shaped slider 61, the support roller 23 rotates counterclockwise to reset to the default state. As the support roller 23 resets to the default state, the electromagnetic rod 53 is energized again to drive the support roller 23 to rotate clockwise again. This cycle repeats so that before the arc-shaped slider 61 of the support seat 22 is completely separated from the support roller 23, the support roller 23 first performs a small-amplitude circumferential reciprocating rotation and shaking stroke. This stroke is designed to prevent the support roller 23 from directly rotating and striking the support seat 22, thus avoiding damage to the support roller 23. Furthermore, the circumferential vibration of the support roller 23 causes the electromagnetic rod 53 at its highest point to attract iron powder inside the first flexible support member 291, resulting in horizontal reciprocating movement. This prevents the iron powder from clumping and sticking together under the pressure of the sheet metal during magnetic fixation, thus reducing the flexibility of the first flexible support member 291. The vibration generated by the circumferential vibration of the support roller 23 is also transmitted to the support seat 22, facilitating the disassembly and separation of the support seat 22 from the fitting column 31 of the transfer frame 3. Once the support seat 22 slides away relative to the support roller 23, completely separating the arc-shaped slider 61 from the support roller 23, the support roller 23 is driven by magnetism to rotate circumferentially.

[0079] As another embodiment of the present invention, the locking frame 41 further includes a drive wheel 44 and a transmission gear 45 rotatably disposed on the base frame 1. The transmission gear 45 meshes with the rack portion 413 disposed on the locking frame 41, and the worm portion 441 disposed on the drive wheel 44 meshes with the worm wheel portion 451 disposed on the transmission gear 45.

[0080] Specifically, such as Figure 4As shown, the locking frame 41 is provided with a rack portion 413, while the drive wheel 44 and the transmission gear 45 are rotatably mounted on the placement base 1. The worm portion 441 of the drive wheel 44 meshes with the worm wheel portion 451 of the transmission gear 45, and the transmission gear 45 meshes with the rack portion 413. The drive wheel 44 can be manually rotated, thereby driving the locking frame 41 to slide vertically through the worm portion 441, the worm wheel portion 451, the transmission gear 45, and the rack portion 413. This facilitates practical operation and use. Furthermore, the worm portion 441 and the worm wheel portion 451 are used to drive the locking frame 41, thereby enabling the locking frame 41 to perform vertical self-locking when the drive wheel 44 is not rotating, thus ensuring the locking stability of the locking frame 41 on the tray body 21.

[0081] Working principle: First, the loading part 211 installs the tray body 21 onto the placement base 1, thereby assembling the tray assembly 2 and the placement base 1 into one unit to hold the sheet metal parts to be stored. Then, the locking frame 41 slides vertically to lock the tray body 21 through the abutment member 42. The support seat 22 is relatively far away, allowing the support roller 23 to rotate. If the electrode plate 213 is energized, the electromagnetic rod 53 is energized and generates magnetism, which drives the support roller 23 to rotate. Subsequently, the electromagnetic... After the rod 53 moves, it is de-energized again and energized again as the support roller 23 rotates, repeating the cycle to achieve continuous rotation of the support roller 23. An inclined air guide surface 2311 is provided on the extension foot 231 of the support roller 23, and an outlet hole 214 is provided on the tray body 21. The rotation of the support roller 23 ventilates the tray body 21 through the rotation of the inclined air guide surface 2311. The support roller 23 has angular momentum due to rotation, so that the support roller 23 is located inside the tray body 21 and acts like a gyroscope.

[0082] When the pallet body 21 and its sheet metal parts need to be transferred, the transfer frame 3 fits against the placement base frame 1, and the fitting post 31 fits into the embedding hole 212 opened on the pallet body 21, thereby making the pallet assembly 2 and the transfer frame 3 a single unit. Then, the pallet body 21 is unlocked using the locking frame 41. At this time, the transfer frame 3 can be directly rolled out of the outside of the placement base frame 1 to take out the pallet body 21, and the pallet body 21 and its sheet metal parts placed on it can be directly moved and transferred to other placement base frames 1 by moving the transfer frame 3. During the transfer process, the pallet body 21 and its sheet metal parts placed on it can be moved directly to other positions on the placement base frame 1. The cross-section of the support roller 23 is in the shape of an upright V-shape. The support seat 22 is relatively close to the support roller 23 on both sides. At this time, the electrode plate 213 performs an action on the electromagnetic rod 53. The electromagnetic rod 53 forms two unclosed magnetic lines of force between the first magnetic element 51 and the second magnetic element 52. When the sheet metal with a large contact surface is placed on the first flexible support 291, the electromagnetic rod 53, the first magnetic element 51 and the second magnetic element 52 provided on the support roller 23 and the support seat 22 form a similar magnetic attraction fixing component, thereby adsorbing and fixing the large sheet metal part to the tray body 21.

[0083] When it is necessary to retrieve the sheet metal parts inside the pallet body 21 on the base frame 1, the drive wheel 44 is rotated, and the transmission gear 45 drives the locking frame 41 to continue to move vertically upward. The horizontal bar 412 moves vertically upward to push against the push-out column 251, thereby causing the locking frame 41 to push against the overturning seat 25 and drive the bearing seat 22 to continue to rotate. At this time, the end of the bearing seat 22 rotates upward to drive the first flexible support member 291 on it to move upward to the top of the pallet body 21, thereby raising the sheet metal parts placed on the first flexible support member 291 to the outside of the pallet body 21.

[0084] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
