Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a material tray transfer device. Background Technology

[0002] In the mass production of electronic components, hardware parts and other products, the material receiving and tray-stacking machine is a key piece of equipment for automated material processing. It is mainly used to neatly arrange scattered materials into the tray according to preset rules. When the tray is full of products, the tray is stacked onto the rack through the tray transfer mechanism.

[0003] In the prior art, such as Chinese Invention Patent No. CN221970637U, entitled "Material Transfer Device," a material transfer device is disclosed. This device includes a frame, a storage rack, and a transfer mechanism. The frame has a material preparation position; the storage rack is movable relative to the frame to the preparation position and has multiple storage positions for storing material trays; the transfer mechanism is located on the frame and configured at the unloading or loading position of the material production equipment. The transfer mechanism has multiple buffer positions for driving the material trays between any storage position and any buffer position. The material transfer device provided in this application allows for tray changing operations at other buffer positions while unloading or loading is being performed at one buffer position, significantly saving tray changing time. Furthermore, after the unloading tray is full, the transfer mechanism drives the full tray to an empty storage position for storage, or after the loading tray is empty, the transfer mechanism drives the empty tray to a storage position for storage, significantly improving the efficiency of material unloading or loading.

[0004] In addition to the above solutions, in the existing technology, during the process of grabbing the material tray, a robotic arm flat plate is used to extend into the bottom of the material tray in the material tray frame. Due to the lifting of a certain distance, the material tray is detached from the material tray support, and then pulled out. If the material tray is sintered and deformed, or if the four corners or rollers of the material tray frame are uneven, it may cause the material tray frame to tilt. At this time, the transfer flat plate extends into the material tray frame, which may cause a collision risk. Moreover, these transfer structures are complex and have high manufacturing costs, which is not conducive to market competitiveness. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a tray transfer device that enables the removal or storage of trays from a tray rack through a simple structure.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a material tray transfer device, including a frame, a material tray conveying device disposed on the frame, a material tray frame disposed on one side of the frame, and a transfer device disposed on the material tray frame that can approach or move away from the material tray conveying device and transfer the material tray on the transmission device. The transfer device includes a transfer frame assembly, a drive mechanism, and an automatic correction and adsorption mechanism.

[0007] In the above technical solution, the automatic correction adsorption mechanism includes a drive arm, a correction seat, and a correction adsorption assembly. The drive arm includes a sliding end and a drive end. The sliding end is slidably connected to the transfer frame assembly, and the drive end is connected to the correction seat.

[0008] In the above technical solution, the correction seat is provided with a connecting part and an assembly part, the connecting part is provided with a slide, the driving end is connected to the correction seat through the slide, and the correction adsorption component is set on the correction seat through the assembly part.

[0009] In the above technical solution, the correction adsorption assembly includes a sensing control component and correction adsorption components that protrude from the first working surface and the second working surface of the correction seat, respectively.

[0010] In the above technical solution, the alignment adsorption component includes an electromagnet and a connecting component that enables the electromagnet to both remain connected to the alignment base and to swing freely relative to the alignment base.

[0011] In the above technical solution, the transfer frame assembly includes a transfer support frame that is movably connected to the material tray frame. A first slide rail is provided on the horizontal working surface of the transfer support frame, and the transfer seat is mounted on the transfer support frame via the first slide rail.

[0012] In the above technical solution, the transfer seat includes a material tray bearing area with two open working ends. The two open ends cooperate with the hollowed-out reserved working area set on the vertical working surface of the transfer support frame to form a transfer channel. A slide rail mounting position is provided extending from one side of the material tray bearing area. A second slide rail is set on the slide rail mounting position, and a position sensor is set between the slide rail and the side of the transfer seat. A slide seat is provided on the lower working surface of the transfer seat, which enables the transfer seat to slide along the first slide rail.

[0013] In the above technical solution, the two flanges of the transfer seat can be driven by a drive structure to adjust the spatial position of the material tray bearing area.

[0014] In the above technical solution, the first slide rail and the second slide rail are arranged perpendicular to each other, and the plane where the second slide rail is located is higher than the plane where the first slide rail is located.

[0015] In the above technical solution, the drive arm is connected to the transfer seat through the second slide rail, so that the deviation correction adsorption component on the deviation correction seat is suspended at the position of the material tray bearing area.

[0016] In the above technical solution, the driving mechanism includes a first driving mechanism for driving the transfer support frame, a second driving mechanism for driving the transfer seat, a third driving mechanism for driving the driving arm, and a fourth driving mechanism for driving the correction seat.

[0017] Compared with the prior art, the present invention has the following beneficial effects: Through the correction and adsorption components in the automatic correction and adsorption mechanism, the edge of the material tray is automatically corrected, and the edge of the material tray can be automatically found and adsorbed, ensuring that the adsorption area is maximized. This is conducive to the stable removal or storage of the material tray from the rack, simplifies the transfer mechanism, effectively reduces manufacturing costs, and improves transfer efficiency and stability. The material tray bearing area can be adjusted according to the size of the material tray, with higher matching, matching the working state of the material tray for clamping and releasing, effectively preventing the material tray from impacting the transfer seat during unloading, and also improving the accuracy of loading.

The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0029] join Figures 1 to 6 A material tray transfer device includes a frame 1, on which a material tray placement mechanism 11 is provided. A material tray conveying device 2 is provided at the working position corresponding to the material tray placement mechanism 11. The device can transfer the material trays transferred by the transfer device 4 from the material tray rack 3 to the working area of ​​the material tray placement mechanism 11, or after the material tray placement mechanism 11 has finished placing the trays, the material tray conveying device 2 will transfer the trays to the working area of ​​the transfer device 4, and the transfer device 4 will transfer the trays to the material tray rack 3.

[0030] For convenient transfer and rational space design, the material tray rack 3 is set opposite to the frame 1, and the transfer device 4 can move close to or away from the material tray conveying device 2 and transfer the material tray 21 on the transmission device.

[0031] Of course, the tray rack 3 includes longitudinal guide rails 31 for mounting and enabling the transfer device 4 to slide along its height direction, and they are symmetrically arranged. The arrangement spacing of the two longitudinal guide rails 31 matches the structure of the transfer device 4. Several tray placement areas are provided on the rear side of the longitudinal guide rails 31.

[0032] Of course, in order to protect the mechanism, a protective frame 10 is also provided outside the frame 1, and a control component 101 is also provided on the protective frame 10.

[0033] Specifically, the transfer device 4 includes a transfer frame assembly, a drive mechanism, and an automatic correction and adsorption mechanism.

[0034] The automatic alignment adsorption mechanism includes a drive arm 41, an alignment seat 42, and an alignment adsorption assembly.

[0035] The drive mechanism includes a first drive mechanism for driving the transfer support frame 45, a second drive mechanism for driving the transfer seat 46, a third drive mechanism for driving the drive arm 41, and a fourth drive mechanism for driving the correction seat 42.

[0036] The transfer frame assembly includes a transfer support frame 45 and a transfer seat 46.

[0037] The transfer support frame 45 consists of a vertical working surface and a horizontal working surface. The two working ends of the transfer support frame 45 along the width direction of the vertical working surface are provided with transfer grooves 450 for matching with two longitudinal guide rails 31, so that the transfer support frame 45 can slide up and down along the height direction of the two longitudinal guide rails 31 under the drive of the first drive mechanism. The hollowed-out reserved working area 453 is provided on the vertical working surface between the transfer grooves 450, so that the space of the material tray placement area is exposed through the hollowed-out reserved working area 453.

[0038] A first slide rail 451 is provided on the horizontal working surface of the transfer support frame 45. A drive mounting plate 452 is provided at one end of the first slide rail 451. The second drive mechanism is mounted through the drive mounting plate 452 and includes a drive motor and a drive rod.

[0039] The transfer seat 46 is mounted on the transfer support frame 45 via the first slide rail 451 and is driven by the second drive mechanism.

[0040] The transfer seat 46 includes a tray carrying area 462 with two open working ends. The two open ends cooperate with the hollowed-out reserved working area 453 set on the vertical working surface of the transfer support frame 45 to form a transfer channel. The tray can be transferred from the tray conveying device 2 to the tray placement area, or from the tray placement area to the position of the tray conveying device 2.

[0041] To prevent the material tray from colliding during the feeding process, the two retaining edges 460 of the transfer seat 46 can be driven by a drive structure to adjust the spatial position of the material tray bearing area 462. That is, the interval between the two retaining edges 460 can be adjusted by a cylinder to accommodate material trays of different sizes. The clamping and releasing of the retaining edges on the material tray by the drive is beneficial to the stability of the transfer process. Of course, this arrangement can also effectively improve the accuracy of the position of the material tray when it is sent to the material tray frame 3. The drive structure can be a cylinder or the like.

[0042] A slide rail mounting position 463 is provided on one side of the material tray bearing area. A second slide rail 47 is provided on the slide rail mounting position. A position sensor 464 is provided between the second slide rail 47 and the stop edge of the transfer seat 46 to sense whether the material tray is located in the material tray bearing area 462. A slide seat 461 is provided on the lower working surface of the transfer seat 46 to allow the transfer seat 46 to slide along the first slide rail 451.

[0043] It is worth mentioning that, in order to ensure that the automatic correction adsorption mechanism works normally in the material tray bearing area 462, the first slide rail 451 and the second slide rail 47 are arranged perpendicular to each other, and the plane where the second slide rail 47 is located is higher than the plane where the first slide rail 451 is located.

[0044] The drive arm 41 includes a sliding end 411 and a drive end 412. The sliding end 411 is slidably connected to the second slide rail 47, and the drive end 412 is connected to the correction seat 42. Of course, a third drive mechanism is provided at the end of the second slide rail 47 for driving the drive arm 41, and a fourth drive mechanism is provided at the drive end 412 for driving the correction seat 42.

[0045] The correction seat 42 is provided with a connecting part and an assembly part. The connecting part is provided with a slide 421. The driving end 412 of the driving arm 41 is connected to the correction seat 42 through the slide 421, and the correction seat 42 can be adjusted vertically. The correction adsorption component is set on the correction seat 42 through the assembly part, so that the correction adsorption component is suspended at the material tray bearing area 462.

[0046] The alignment adsorption assembly includes a sensing control element 43 and an alignment adsorption element 44.

[0047] Both the sensing control component 43 and the correction adsorption component 44 are located at the reserved positions in the assembly part. Of course, a material tray position sensor 431 is also provided at the reserved positions in the assembly part. The correction adsorption component 44 is used to sense the position of the material tray and protrudes from the correction seat 42. In this solution, as a preferred embodiment, four correction adsorption components 44 are provided, which protrude from the first working surface and the second working surface of the correction seat 42, respectively.

[0048] The alignment adsorption component includes an electromagnet 441 and a connector 442. The connector 442 allows the electromagnet 441 to remain connected to the alignment base 42 while also being able to move freely relative to the alignment base 42. Figure 6 In other words, there is an angle between the inner working surface of the electromagnet 441 and the working surface of the correction seat 42 when the electromagnet is not in operation. That is, the electromagnet 441 can protrude from the correction seat 42 and has relative space for movement. Of course, as a preferred option, the electromagnet 441 is cylindrical.

[0049] The operating principle in the above embodiments is as follows: taking the transfer of the material tray from the material tray conveying device 2 to the material tray frame 3 as an example.

[0050] The first drive mechanism activates, driving the transfer support frame 45 to move up or down to the height of the tray conveying device 2, i.e., level with the height of the tray conveying device 2's platform. Subsequently, the second drive mechanism drives the transfer seat 46 to align its two open ends with the tray on the tray conveying device 2's platform. To prevent the attracted tray from colliding with the transfer seat 46 after being pulled out, the gap between the two retaining edges 460 can be adjusted by a cylinder to be larger than the tray's size when the tray is pulled out. The third drive mechanism drives the drive arm 41 to move. At this time, since the electromagnet 441 initially remains connected to the correction seat 42 and can freely sway relative to it, when it moves the correction adsorption component close to the tray, the outer working end of the electromagnet 441 automatically finds the tray's plane and aligns with it, ensuring maximum contact area. The sensing control component 43 senses... When the electromagnet 441 contacts the tray, it is energized and attracts the tray. The drive arm 41 moves, pulling the tray back to the tray bearing area 462 on the transfer seat 46. The position sensor 464, located between the second slide rail 47 and the side rail of the transfer seat 46, senses the tray and then de-energizes it. The electromagnet 441 releases the tray. At this time, the two side rails 460 move under the drive of the cylinder to clamp the tray, which not only ensures the stability of the transfer process but also guides the tray, making it easier to accurately align with the tray placement area. Driven by the fourth drive mechanism, the correction seat 42 moves up to the top of the tray and is then moved by the drive arm 41 to the other end of the tray, that is, the end near the tray conveyor 2 platform. It automatically finds the plane again and attracts the tray. The drive arm 41 moves, pushing the tray to the tray placement area. During the operation, the position sensor 464 detects the tray to prevent it from being unloaded.

[0051] Of course, it should be noted that several sensors are also installed on the transfer seat to sense the position and status of the material tray, ensuring the monitoring of the material tray.

[0052] Correspondingly, the principle of transferring the material tray from the tray rack 3 to the tray conveyor 2 is the same. Both can be automatically leveled by electromagnets, making the transfer action more efficient, stable, and precise. Compared with the existing technology that uses a robotic arm to reach into the bottom of the tray and pull it out, this solution can automatically find any plane of the tray to achieve maximum contact and adsorption between the two, regardless of whether the tray is sintered and deformed, or whether there are problems with the four corners of the tray rack or the rollers. The electromagnet is driven by the alignment seat, so that the outer working end automatically finds any plane of the tray and the two achieve maximum contact. With the help of the transfer seat, the two baffles that drive the adjustment of the spatial position of the tray bearing area can be adjusted by the drive structure, so that the pushing in and pulling out are both position changes from small space to large space, avoiding the risk of collision. Moreover, the structure of this application is simple, the manufacturing cost is low, and it has strong market competitiveness.
