Description

Technical Field

[0001] The utility model relates to the technical field of mechanical automation, in particular to an automatic material tray taking and placing mechanism. Background Art

[0002] In the automated production process, the automatic placement of material trays is a key step in ensuring the continuity and efficiency of the production process. Through automation technology, material trays can be quickly and accurately placed, thereby improving production efficiency, reducing labor costs, and ensuring the consistency of product quality. At present, most automated equipment adopts the following two methods: 1. Directly placing and placing materials on the top layer of the stack, and then directly removing empty or full trays; 2. The top layer of the stack is divided into a fixed platform, and then the material trays on the platform are placed and placed, and finally the material trays on the platform are taken to the empty or full tray stack. The first method has high requirements for the hardness of the material tray and poor positioning accuracy. Because the material tray is not hard enough, it is not conducive to secondary positioning on the top layer. Moreover, due to the direct placement of the material trays on the top layer of the stack, the cumulative error is relatively large. The second method is not compact and occupies a large space.

[0033] like Figure 1As shown, the present invention provides an automatic material tray pick-up and placement mechanism, comprising a plurality of first lifting mechanisms 1, a pick-up and placement tray mechanism 2 having the same number of first lifting mechanisms 1, and a tray moving mechanism 3. For example, the first lifting mechanisms 1 and the pick-up and placement tray mechanism 2 can be arranged as one or more groups, such as two groups. The first lifting mechanisms 1 are used to transport the material tray 5 to the position of the pick-up and placement tray mechanism 2; the pick-up and placement tray mechanism 2 comprises a pick-up and placement rack 21 and a second lifting mechanism 22 for controlling the lifting and lowering of the pick-up and placement rack 21. The pick-up and placement rack 21 is provided with a plurality of suction cups 23 for sucking the material tray 5; the tray moving mechanism 3 comprises a tray moving platform 31 and a moving mechanism 32 for controlling the movement of the tray moving platform 31. The tray moving platform 31 is located at the lower side of the pick-up and placement rack 21. Under the action of the moving mechanism 32, the tray moving platform 31 moves from the lower side of the pick-up and placement rack 21 of the plurality of pick-up and placement tray mechanisms 2 to the loading position. When the first lifting mechanisms 1 and the pick-up and placement tray mechanism 2 are arranged as multiple groups, the position of one of the pick-up and placement tray mechanisms 2 can be designed as the loading position.

[0034] In the present utility model, the first lifting mechanism 1 carries the material tray 5 and rises to the position of the pick-up and placement mechanism 2, the second lifting mechanism 22 drives the pick-up and placement rack 21 to descend, and after the suction cup 23 on the pick-up and placement rack 21 sucks the material tray 5, the second lifting mechanism 22 drives the pick-up and placement rack 21 to rise, and the moving mechanism 32 controls the tray transfer platform 31 to move to the bottom of the material tray 5, and places the material tray 5 on the tray transfer platform 31; under the action of the moving mechanism 32, the tray transfer platform 31 carries the material tray 5 to the loading position, and then the relevant equipment performs the corresponding material taking and placing work.

[0035] The automatic material tray picking and placing mechanism of the present invention has the advantages of high positioning accuracy, low requirement on material tray hardness, compact structure, small space occupation, comprehensive functions and easy operation, which provides strong support for automated production. Through the coordinated work of the first lifting mechanism 1, the picking and placing tray mechanism 2 and the tray moving mechanism 3, the automatic picking and placing and movement of the material tray are realized, which greatly improves the production efficiency; multiple groups of first lifting mechanisms 1 and picking and placing tray mechanisms 2 can be set as needed to adapt to different scales and production needs; the design of the suction cup 23 ensures the stability and safety of the material tray during movement; the utility model can be applied to various scenarios that require automatic processing of material trays, such as electronic product assembly lines, food processing lines, etc., and can significantly improve production efficiency and quality.

[0036] In one embodiment, the first lifting mechanism 1 includes a Z-axis linear module 11, a bracket 12, and a tray 13. The bracket 12 is connected to the sliding seat of the Z-axis linear module 11. The tray 13 is detachably connected to the bracket 12 and is used to support the material tray 5. For example, the tray 13 is connected to the top plate of the bracket 12 via multiple connecting columns 14. The size of the tray 13 is larger than the size of the top plate of the bracket 12 to improve the support stability of the material tray 5.

[0037] In one embodiment, if Figure 1 As shown, the automatic tray pick-up and placement mechanism also includes a tray support assembly 4, which is located at the lower end of the first lifting mechanism 1. The tray support assembly 4 includes a base 41, and the base 41 is provided with a groove 411 adapted to the bracket 12. Support seats 42 for supporting the tray 5 are provided on both sides of the groove 411 on the base 41. The support seats 42 are slidably connected to the base 41, and the movement direction of the support seats 42 is perpendicular to the movement direction of the pick-up and placement rack 21 of the tray pick-up and placement mechanism 2, which facilitates the arrangement of multiple tray support assemblies 4. For example, two fixed plates 43 parallel to the support seats 42 are provided on the top of the base 41, and the two support seats 42 are located between the two fixed plates 43. The support seats 42 are slidably connected to the fixed plates 43 to achieve the sliding of the support seats 42, which facilitates the placement of the tray 5. Two first limiting seats 44 are spaced apart and arranged opposite to each other on the support seat 42 on each side. The first limiting seats 44 include a first vertical plate 441 and a second vertical plate 442 that are perpendicular to each other. The four first limiting seats 44 on the two support seats 42 constitute a limited placement space for the material tray 5. A second limiting seat 27 corresponding to the first limiting seat 44 is also provided on the lower side of the tray pick-up and placement mechanism 2. Specifically, the first vertical plates 441 on the two first limiting seats 44 on the support seat 42 on the same side are parallel, and the second vertical plates 442 extend toward each other; the first vertical plates 441 on the two adjacent first limiting seats 44 on the support seats 42 on both sides extend toward each other, and the second vertical plates 442 are parallel; the second limiting seat 27 has the same structure as the first limiting seat 44.

[0038] In this embodiment, the arrangement of the tray support assembly 4 facilitates the pre-placement of multiple trays 5 on the support seat 42, thus saving time for the automatic placement of the trays 5. When placing the trays 5, the support seat 42 can be pulled out first, and then the trays 5 can be stacked in sequence in the limited placement space formed by the two support seats 42 and their four first limiting seats 44. After the trays 5 are stacked, the support seat 42 is pushed into the lower side of the pick-up and placement tray mechanism 2, so that the first lifting mechanism 1 can carry the stacked trays 5 and rise to the position of the pick-up and placement tray mechanism 2 in the next step; the first limiting seat 44 extends upward until it contacts the second limiting seat 27. During the ascent of the first lifting mechanism 1, the first limiting seat 44 will still limit the trays 5 to prevent the trays 5 from shifting.

[0039] Furthermore, the first limiting seat 44 is located outside the support seat 42, and a fixed block 45 is provided between the first limiting seat 44 and the support seat 42. The upper surface of the fixed block 45 is flush with the upper surface of the support seat 42. The first limiting seat 44 and the fixed block 45 or / and the fixed block 45 and the support seat 42 can be adjusted along the X-axis and / or the Y-axis. The second limiting seat 27 can be adjusted along the X-axis and / or the Y-axis. The adjustable setting of the first limiting seat 44 and the second limiting seat 27 facilitates the adjustment of the spacing between the four first limiting seats 44 and the four second limiting seats 27 to accommodate the positioning of trays 5 of different sizes.

[0040] In one embodiment, the first vertical plate 441 and the second vertical plate 442 of the first limit seat 44 are respectively provided with first adjustment holes 443 extending along the X-axis and Y-axis directions, wherein the X-axis direction is the movement direction of the pick-up and placement rack 21 of the pick-up and placement tray mechanism 2, and the Y-axis direction is the movement direction of the support seat 42 of the tray support assembly 4; the fixed block 45 is provided with a threaded hole, and a fastening screw is provided in the first adjustment hole 443 and the threaded hole to achieve positioning and cooperation between the first adjustment hole 443 and the threaded hole. The second limit seat 27 can be set on the support 6 through the "L-shaped" block 28. The "L-shaped" block 28 is provided with a second adjustment hole extending along the X-axis and Y-axis directions. The position of the second limit seat 27 is adjusted by the positioning and cooperation between the second adjustment hole of the "L-shaped" block 28 and the threaded hole on the support 6.

[0041] In this embodiment, the first limit seat 44 is connected to the support seat 42 through a fixed block 45, and can be adjusted along the X-axis and Y-axis directions to facilitate adjustment of the spacing between the four first limit seats 44. Synchronously, the position of the second limit seat 27 is also adjusted accordingly to adapt to the limitation of material trays 5 of different sizes; the upper surface of the fixed block 45 is flush with the upper surface of the support seat 42 to ensure that the material tray 5 can be placed stably.

[0042] In one embodiment, a sensor 46 is provided on the base 41 , and the sensor 46 is used to detect the existence and position of the material tray 5 so that a corresponding mechanism can automatically perform a pick-up and place operation.

[0043] In one embodiment, a handle 47 is provided between the two support bases 42 . The provision of the handle 47 facilitates an operator to manually move or adjust the position of the support base 42 .

[0044] In one embodiment, a plurality of limiting members 24 are provided on the pick-and-place rack 21 . The limiting members 24 are movably connected to the pick-and-place rack 21 , and the suction cups 23 are provided on the limiting members 24 .

[0046] In this embodiment, the position of the limiting member 24 can be adjusted along the circumference of the pick-up and placement rack 21, and can also be adjusted along the length direction of the limiting member 24, so that the position of the suction cup 23 is flexible to accommodate the suction of material trays 5 of different sizes.

[0047] In one embodiment, the moving mechanism 32 includes a rodless cylinder 321 and a slide rail 322. The tray shifting platform 31 is connected to the sliding seat of the rodless cylinder 321. The slide rail 322 is located on the lower side of the pick-up and placement rack 21 and can be set on the support 6. The slide rail 322 is provided in two groups. The two groups of slide rails 322 are respectively located on the two side edges of the tray shifting platform 31. The tray shifting platform 31 is slidably connected to the slide rail 322 to ensure the smooth movement of the tray shifting platform 31.
