Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a material tray rotation and repositioning device. Background Technology

[0002] An automatic tray changer is a mechanical device used to automatically exchange empty and full trays. The tray changing device is the core component for switching tray positions. In practical applications, the applicant has found several significant shortcomings in the current tray changing device. First, the existing device has a complex structural design with many mechanical transmission links, which not only increases manufacturing costs but also affects operational reliability. Furthermore, it makes it difficult to flexibly change trays between multiple stations. Second, the clamping mechanism used to hold and fix the trays lacks stability, posing a risk of tray loosening or even slipping during operation, seriously affecting production continuity and operational safety. Therefore, it is necessary to optimize the structure of the existing changing device to simplify the mechanism, improve multi-station compatibility, and enhance the clamping stability of the trays, thereby improving the overall performance of the automatic tray changer. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a material tray rotation and repositioning device, the specific technical solution of which is as follows: A material tray rotation and repositioning device includes a rotary power mechanism, a large turntable, a material tray clamping mechanism, a slide rail assembly, a shaft, a limit bearing, a fixed clamping plate, and a pushing mechanism. The rotary power mechanism drives the large turntable to rotate. The large turntable is slidably mounted with the material tray clamping mechanism via the slide rail assembly. There are multiple material tray clamping mechanisms distributed circumferentially around the central axis of the large turntable. The center of the large turntable is rotatably connected to the center of the fixed clamping plate via the shaft. A bearing is fitted between the shaft and the fixed clamping plate, allowing relative rotation between the large turntable and the fixed clamping plate. A limit bearing is installed at the inner end of the material tray clamping mechanism. The fixed clamping plate has a limit groove and a push-out groove. The limit bearing is located in the limit groove, and the limit groove communicates with the push-out groove. When the material tray clamping mechanism rotates to the position where the limit bearing faces the push-out groove, the pushing mechanism drives the material tray clamping mechanism to move along the slide rail assembly closer to the material tray.

[0004] As a preferred embodiment of this utility model, the rotary power mechanism includes a motor, a synchronous belt transmission assembly, a rotary shaft, and a flange shaft. The motor drives the rotary shaft to rotate through the synchronous belt transmission assembly, and the rotary shaft is fixedly connected to the center of the large turntable through the flange shaft.

[0005] As a preferred embodiment of this utility model, the material tray clamping mechanism includes a movable seat, a bushing, a petal-shaped air shaft, a push rod, and an opening and closing power component. A limit bearing is installed at the end of the movable seat, a bushing is installed in front of the movable seat, and a petal-shaped air shaft is installed in front of the bushing. The outer circumference of the petal-shaped air shaft is provided with multiple dividing grooves, which are circumferentially distributed around the central axis of the petal-shaped air shaft. The push rod is movably mounted inside the petal-shaped air shaft. The opening and closing power component drives the push rod to move back and forth. The opening and closing power component is a cylinder. The front end of the push rod is provided with a tapered surface. The push rod drives the petal-shaped air shaft to expand and clamp the center of the material tray.

[0006] As a preferred embodiment of the present invention, the material tray clamping mechanism further includes a small bearing, a bushing, and a connecting sleeve. The bushing is fitted with a small bearing and a bushing. There are two small bearings, and the bushing is located between the two small bearings. The rear end of the connecting sleeve is fitted inside the small bearing, and the front end of the connecting sleeve is connected to a petal-shaped air shaft.

[0007] As a preferred embodiment of this utility model, the petal-shaped air shaft has an expansion hole at its center. The inner diameter of the expansion hole is smaller than the outer diameter of the push rod. The push rod extends into the expansion hole to expand the petal-shaped air shaft.

[0008] In a preferred embodiment of this utility model, the pushing mechanism includes a fixed base, a longitudinal pushing cylinder, a longitudinal pushing block, a longitudinal limiting cylinder, a longitudinal limiting head, a transverse pushing cylinder, and a transverse pushing block. The longitudinal pushing cylinder is installed on the side of the fixed base. The longitudinal pushing cylinder drives the longitudinal pushing block to push the material tray clamping mechanism to move longitudinally. The longitudinal limiting cylinder drives the longitudinal limiting head to move longitudinally. The longitudinal limiting head is lower than the longitudinal pushing block by one material tray height. The transverse pushing cylinder is installed at the fixed base. The transverse pushing cylinder drives the transverse pushing block to push the material tray clamping mechanism to move transversely.

[0009] As a preferred embodiment of this utility model, the longitudinal pushing block is away from the fixed positioning plate, and the transverse pushing block can be moved into or out of the fixed positioning plate.

[0010] Beneficial effects: The large turntable slides and mounts a tray clamping mechanism via a slide rail assembly. There are multiple tray clamping mechanisms distributed around the central axis of the large turntable. A limit bearing is installed at the inner end of the rotation power mechanism. The limit bearing is located in a limit groove. As the large turntable rotates, the tray clamping mechanism can clamp the tray to perform multiple station changes, meeting diverse needs. Moreover, the pushing mechanism can drive the tray clamping mechanism to move along the slide rail assembly closer to the tray, preventing the tray clamping mechanism from affecting other processing steps when no change is needed.

[0014] like Figure 1 and 2As shown, a material tray rotation and repositioning device includes a rotary power mechanism 1, a large turntable 2, a material tray clamping mechanism 3, a slide rail assembly 4, a shaft core 5, a limit bearing 6, a fixed clamping plate 7, and a pushing mechanism 8. The rotary power mechanism 1 drives the large turntable 2 to rotate. The large turntable 2 is slidably mounted with the material tray clamping mechanism via the slide rail assembly 4. The slide rail assembly 4 consists of common slide rails and sliders. There are multiple material tray clamping mechanisms 3 distributed circumferentially around the central axis of the large turntable 2. The center of the large turntable 2 is rotatably connected to the center of the fixed clamping plate 7 via the shaft core 5. A bearing is fitted between the shaft core 5 and the fixed clamping plate 7, so that the large turntable 2 and the fixed clamping plate 7 can rotate relative to each other. When the large turntable 2 rotates, it will not cause the fixed clamping plate 7 to rotate. The inner end of the material tray clamping mechanism 3 is equipped with a limiting bearing 6. The fixed clamping plate 7 is provided with a limiting circular groove 71 and an ejection groove 72. The limiting bearing 6 is located in the limiting circular groove 71 and can limit the position of the material tray clamping mechanism 3. The limiting circular groove 71 and the ejection groove 72 are connected. When the material tray clamping mechanism 3 rotates to the position where the limiting bearing 6 is facing the ejection groove 72, the pushing mechanism 8 drives the material tray clamping mechanism 3 to move along the slide rail assembly 4 and approach the material tray. In this embodiment, there are 4 material tray clamping mechanisms 3, which can transfer the material tray to 4 different work stations to complete processes such as feeding empty material trays, loading material, unloading full material trays, and inspection.

[0015] Specifically, the rotating power mechanism 1 includes a motor 11, a synchronous belt drive assembly 12, a rotating shaft 13, and a flange shaft 14. The motor 11 drives the rotating shaft 13 to rotate through the synchronous belt drive assembly 12. The synchronous belt drive assembly 12 is composed of a common synchronous belt and a synchronous pulley. The rotating shaft 13 is fixedly connected to the axis of the large turntable 2 through the flange shaft 14. When the rotating shaft 13 rotates, it will drive the large turntable 2 to rotate.

[0016] like Figure 3 and 4As shown, the material tray clamping mechanism 3 includes a movable seat 31, a bushing 32, a petal-shaped air shaft 33, a push rod 34, and an opening and closing power component 35. A limit bearing 6 is installed at the end of the movable seat 31, a bushing 32 is installed in front of the movable seat 31, and a petal-shaped air shaft 33 is installed in front of the bushing 32. The petal-shaped air shaft 33 has multiple partition grooves on its outer periphery, which are distributed circumferentially around the central axis of the petal-shaped air shaft 33. The push rod 34 is movably mounted inside the petal-shaped air shaft 33. The opening and closing power component 35 drives the push rod to move back and forth. The opening and closing power component is a cylinder. The front end of the push rod 34 has a tapered surface. The push rod 34 drives the petal-shaped air shaft 33 to expand and clamp the center of the material tray. In addition, the tray clamping mechanism includes a small bearing 36, a bushing 37, and a connecting sleeve 38. The small bearing 36 and bushing 37 are housed inside the bushing 32. There are two small bearings, and the bushing is located between the two small bearings. The rear end of the connecting sleeve 38 is fitted inside the small bearing 36, and the front end of the connecting sleeve 38 is connected to the petal-shaped air shaft 33. The petal-shaped air shaft 33 has an expansion hole 33a at its center. The inner diameter of the expansion hole 33a is smaller than the outer diameter of the push rod 34. The push rod 34 extends into the expansion hole 33a, causing the petal-shaped air shaft to expand and thus clamp the tray. The opening and closing power component 35 drives the push rod to move backward to reset, thereby removing the tray. The mechanical drive structure is stable and reliable.

[0017] like Figure 5 and 6 As shown, the pushing mechanism 8 includes a fixed base 81, a longitudinal pushing cylinder 82, a longitudinal pushing block 83, a longitudinal limiting cylinder 84, a longitudinal limiting head 85, a transverse pushing cylinder 86, and a transverse pushing block 87. The fixed base 81 can be fixedly installed on the machine frame via a connecting rod. The longitudinal pushing cylinder 82 is installed on the side of the fixed base 81. The longitudinal pushing cylinder 82 drives the longitudinal pushing block 83 to push the tray clamping mechanism to move longitudinally. The longitudinal limiting cylinder 84 drives the longitudinal limiting head to move longitudinally. The longitudinal limiting head 85 is lower than the longitudinal pushing block by one tray height. When taking trays stacked together from above, one tray can be taken to prevent the trays on the next layer from falling. The transverse pushing cylinder 86 is installed at the fixed base 81. The transverse pushing cylinder 86 drives the transverse pushing block to push the tray clamping mechanism to move transversely. The longitudinal pushing block is away from the fixed clamping plate 7. The transverse pushing block can move into or out of the fixed clamping plate 7. The longitudinal pushing block can be used to push empty trays, and the transverse pushing block can be used to push trays that are full of material.

[0018] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be considered that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
