Abstract
Description
Technical Field
[0001] This utility model relates to the field of receiving devices, and in particular to an automatic misaligned receiving device. Background Technology
[0002] Existing material receiving devices typically use linear motors to achieve staggered material receiving. This involves a robotic arm vertically gripping the material and moving it to a staggered position. Precise control coordinates with the linear motor to achieve automatic material replenishment and high-speed, high-precision staggered material receiving between different processes. However, this type of receiving device often suffers from the following drawbacks in multi-station transfer processing of products:
[0003] 1. Insufficient positioning accuracy: Existing material platforms often cannot accommodate positional shifts between workstations, resulting in the need for manual secondary adjustments of materials in complex processes;
[0004] 2. Low efficiency: The single-station, one-by-one gripping mode has limited efficiency and is difficult to meet the needs of high-speed production lines.
[0005] 3. Poor adaptability: It uses fixed fixtures, which cannot be compatible with materials of different sizes, and it cannot automatically identify and replenish materials at workstations where materials are missing;
[0006] 4. High maintenance costs: The mechanical structure is relatively complex, moving parts are prone to wear, and frequent adjustments are required;
[0007] 5. Inability to automatically replenish material: After NG material is discarded, the existing equipment cannot automatically replenish the material at the turntable station when there is a shortage of material, resulting in a final tray shortage rate of 5%-10%, which requires manual replenishment of material on each tray. Utility Model Content
[0008] To address the aforementioned issues, this invention provides an automatic staggered material receiving device, which is applied to the material transfer process in automated production lines. It is particularly suitable for scenarios requiring multi-station staggered material receiving, such as electronic component assembly and precision parts processing. Through the collaboration of mechanical structure and control system, it precisely controls the station offset trajectory and material gripping, achieving high-speed and high-precision staggered material receiving between different processes, thereby improving the efficiency and accuracy of material transfer.

Detailed Implementation
[0030] The present invention will now be described in further detail with reference to the accompanying drawings.
[0031] like Figure 1 As shown, the automatic staggered receiving device in this embodiment includes a base plate 1, which is generally mounted on a workbench (not shown in the figure). A turntable rotation module 2, a staggered receiving module 3, a tray-splitting module 4, and a pick-and-place module 5 are mounted on the base plate 1. The staggered receiving module 3 is located between the turntable rotation module 2 and the tray-splitting module 4, while the turntable rotation module 2, the staggered receiving module 3, and the tray-splitting module 4 are all within the operating range of the pick-and-place module 5.
[0032] In addition, a loading robot and an NG tray unloading line can be installed on the base plate 1 (not shown in the figure). The loading robot can be used to load materials onto the turntable turnover module 2, and the NG tray unloading line can be used to process unqualified materials.
[0033] like Figure 2 As shown, the turntable rotation module 2 includes a rotating disk 21. A rotating motor 22 is connected to the center of the bottom of the rotating disk 21. The rotating motor 22 is mounted on the base plate 1 via a mounting bracket 23. Multiple material trays 6 can be evenly placed on the top circumference of the rotating disk 21 (one material tray 6 is omitted in the figure to clearly show the structure of the rotating disk 21). Thus, the operation of the rotating motor 22 can drive the turntable and each material tray 6 on it to rotate, so that each material tray 6 and the material on it can be transferred or processed sequentially to the corresponding position through intermittent rotation. The rotation angle and sequence can be set according to the program, and it has high-precision rotation control capability.
[0034] Preferably, a plurality of notches 24 are uniformly formed on the circumference of the rotating disk 21, and a plurality of support plates 25 are uniformly installed thereon. The size of each support plate 25 is larger than that of each notch 24 and is located directly above each notch 24. Thus, the support plates 25 protrude from the surface of the rotating disk 21, which facilitates the identification and placement of the material tray 6.
[0035] Preferably, the material tray 6 can be composed of multiple fixtures arranged side by side.
[0036] like Figure 3 As shown, the staggered receiving module 3 includes a first linear motor 31 that extends horizontally (extending in the front-to-back direction, with the other two sides being the left and right sides). A receiving plate 32 is slidably mounted on the top of the first linear motor 31, and a material tray 6 can be placed on the receiving plate 32. The operation of the first linear motor 31 can drive the receiving plate 32 and the material tray 6 and the material on it to move back and forth.
[0037] Preferably, the first linear motor 31 is mounted on the base plate 1 via a mounting platform 33.
[0038] The misaligned receiving module 3 has a bidirectional misalignment function, which can accurately pick up the parts to be processed or assembled, and automatically fill in the missing parts by performing misalignment and replenishment operations, ensuring replenishment and transferring them to the tray distribution module 4. Its positioning accuracy can reach ±0.05mm, and the maximum horizontal moving speed is 500mm / s, which is suitable for the rapid and accurate picking and transfer of small parts.
[0039] like Figure 4 As shown, the tray-splitting module 4 includes a conveying frame 41 extending front to back and open at the top (part of its structure is omitted in the figure). A linear module 42 extending front to back is located at the bottom of the conveying frame 41. A top-loading cylinder 43 is slidably mounted on the top of the linear module 42. A conveying plate 44 is connected to the piston rod at the top of the top-loading cylinder 43, and the conveying plate 44 can hold the trays 6. Thus, the linear module 42 can drive the top-loading cylinder 43 and the conveying plate 44 to move back and forth, moving the trays 6 to the front or rear of the conveying frame 41 for tray-splitting and splitting operations. The operation of the top-loading cylinder 43 can lift and lower the conveying plate 44 and the trays 6 on it.
[0040] Preferably, a limiting frame 45 with side openings is provided at the upper part of both the front and rear ends of the material conveying frame 41. The limiting frame 45 can be used to limit the passing material tray 6.
[0041] Preferably, a lifting frame 46 is provided at the lower part of the front section and / or rear section (the rear section is taken as an example in the attached figure), and the lifting frame 46 is connected to a lifting cylinder 47. Under the operation of the lifting cylinder 47, the lifting frame 46 can be raised and lowered to perform operations such as tray placement and tray separation on the material tray 6 that has moved to the rear section of the material frame 41.
[0042] The tray-splitting module 4 can tray, separate, and transfer materials with a tray-splitting accuracy of ±0.1mm and is compatible with various sizes of trays 6.
[0043] like Figure 5 As shown, the material handling module 5 includes a second linear motor 51 extending left and right. Two vertically arranged electric slides 52 are slidably mounted on the front side of the second linear motor 51, and a material handling rack 53 is slidably mounted on the front side of each of the two electric slides 52. Multiple material handling suction heads 54 arranged in multiple rows and columns are installed at the bottom of the material handling rack 53. Thus, the operation of the second linear motor 51 and each electric slide 52 can drive each material handling rack 53 and each material handling suction head 54 on it to move left and right and rise and fall, thereby picking up or putting down materials from the material trays 6 of other mechanisms.
[0044] In addition, one of the pick-and-place racks 53 and its pick-and-place suction heads 54 can move between the rotating disk 21 of the turntable rotation module 2 and the receiving plate 32 of the staggered receiving module 3, and the other pick-and-place rack 53 and its pick-and-place suction heads 54 can move between the receiving plate 32 of the staggered receiving module 3 and the middle section of the conveying frame 41 of the tray-splitting module 4.
[0045] Preferably, the second linear motor 51 is mounted on the front side of a support frame 55, which is mounted on the base plate 1.
[0046] The automatic misaligned material receiving device in this embodiment has the following working steps during use.
[0047] S1: The material is loaded onto the material tray 6 of the rotating disk 21 of the turntable turnover module 2, and transported to the designated position near the misaligned receiving module 3 as the rotating disk 21 rotates.
[0048] S2: The material tray 6 on the rotating disc 21 is transferred to the receiving plate 32 of the misaligned receiving module 3 by the material pick-up and drop-off rack 53 on one of the electric slides 52 and the material pick-up and drop-off suction heads 54 on it, and the misaligned receiving module 3 is used to perform misaligned material and replenishment operations.
[0049] S3: The material tray 6 on the receiving plate 32 of the misaligned receiving module 3 is transferred to the material conveying plate 44 raised in the middle section of the material conveying frame 41 of the tray-splitting module 4 by the material pick-up and place-up rack 53 on one of the electric slides 52 of the material pick-up and place-up module 5 and the material pick-up and place-up suction head 54 on it.
[0050] S4: The top cylinder 43 of the tray-splitting module 4 operates to lower the conveying plate 44 and the tray 6 on it, and then moves it to the front or rear of the conveying frame 41 through the linear module 42 for tray-splitting, tray-splitting and other operations.
[0051] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
