Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, and particularly relates to a flipping clamping mechanism. Background Technique

[0002] In the automated equipment of electronic products, clamping structures are often used. Among various product commutation structures, the flipping mechanism is particularly poor in stability and high in design difficulty. Because electronic products are relatively small and fragile, the products are prone to move or be clamped and damaged during the up-and-down flipping process, and a flexible force is required for clamping.

[0003] With the rapid development of the automation industry, the efficiency requirements for equipment are also constantly increasing. Handling one product at a time often fails to meet the requirements of high efficiency. Handling multiple products at a time can often gain higher recognition in the market. At the same time, due to the need to reduce equipment costs and improve equipment competitiveness, the equipment needs to be compatible with as many different models of products as possible. For example, some products need to be flipped, while some products do not need to be flipped. Therefore, there is an urgent need to develop a positioning mechanism that can not only flexibly clamp products, but also efficiently position multiple products at one time and be compatible with different assembly processes.

[0004] After retrieval, the patent number CN202220046293.7 discloses a clamping mechanism, which includes a base body, a fixed clamping component, a movable clamping component and a driving mechanism. The fixed clamping component is fixed to the base body, and the fixed clamping component is used to clamp the workpiece alone. The movable clamping component is movably arranged on the base body in the left-right direction, and the movable clamping component is used to clamp the workpiece alone. The driving mechanism is connected to the base body and the movable clamping component, and the driving mechanism is used to drive the movable clamping component to move in the left-right direction to adjust the distance between the movable clamping component and the fixed clamping component in the left-right direction.

[0005] The fixed clamping component of the clamping mechanism can clamp one end of the workpiece alone, and the driving mechanism can adjust the distance between the movable clamping component and the fixed clamping component in the left-right direction according to the size of the workpiece in the left-right direction, so that the movable clamping component can clamp the other end of the workpiece alone to clamp both ends of the workpiece, and it can be applicable to clamping workpieces of different specifications. However, when using this clamping mechanism to clamp products, it cannot flip the products while clamping, which reduces the practical efficiency of the clamping mechanism, and it cannot clamp multiple products with different processes at the same time. Therefore, in view of the above problems, we have made changes and innovations to the original clamping mechanism. Content of the Utility Model

[0006] The purpose of the utility model is to provide a flipping clamping mechanism to solve the problems in the above background technique that the current clamping mechanisms on the market cannot flip the products while clamping, which reduces the practical efficiency of the clamping mechanism, and cannot clamp multiple products with different processes at the same time.

[0026] Please refer to Figures 1-8 , the present utility model provides a technical solution: a flipping and clamping mechanism, including a first cylinder 1, a rotating shaft 3 and a rotating track 9.

A rotating connecting plate 10 is connected to the lower surface of the rotating track 9, and a bracket 19 is connected to the rear of the rotating track 9. An oil storage tank 22 is installed in front of the bracket 19.

[0027] One end of the first cylinder 1 is fixedly installed with a floating joint 12 to form a telescopic structure, and a U-shaped plate 13 is connected to one side of the floating joint 12. A slide rail 11 is connected to the lower surface of the U-shaped plate 13, and the U-shaped plate 13 is connected to the first cylinder 1 through the floating joint 12 to form a sliding structure. The installation of the first cylinder 1 can drive the clamping mechanism to flip.

[0028] The rotating shaft 3 is installed on the upper surface of the bottom plate 2, and rotating connecting plates 10 are symmetrically installed at both ends of the rotating shaft 3 to form a rotating structure. A cam follower 14 is installed on the lower surface of the rotating connecting plate 10, and the rotating track 9 is connected to the upper surface of the rotating connecting plate 10. A chute is provided on the rotating track 9. The rotating connecting plate 10 can rotate on the rotating shaft 3.

[0029] The bracket 19 is installed at the rear side position of the bottom plate 2, and the second cylinder 4 is installed in front of the bracket 19. A second slider 7 is connected to the upper surface of the second cylinder 4 to form a sliding structure. A pressing plate 6 is installed on the upper surface of the second slider 7, a first slider 5 is installed in front of the pressing plate 6, and a fixed track 8 is connected to the rear of the first slider 5. The installation of the second cylinder 4 can clamp the product 17.

[0030] A connecting sleeve 20 is installed on the rotating shaft 3, and a buckle 21 is provided on the lower surface of the connecting sleeve 20 to form an opening and closing structure. The oil storage tank 22 is installed on the upper surface of the connecting sleeve 20, and two groups of oil outlets 23 are symmetrically installed on both sides of the oil storage tank 22. An oil inlet 24 is installed on the upper surface of the oil storage tank 22, and a valve 25 is installed outside the oil inlet 24. The installation of the oil storage tank 22 can apply lubricating oil to the rotating shaft 3 to prevent the two ends of the rotating shaft 3 from rusting.

[0031] Working principle: When using this flipping and clamping mechanism, first, the slide rail 11 and the cylinder 1 are fixed on the bottom plate 2. The floating joint 12 and the U-shaped plate 13 are fixed on the cylinder 1 and can make reciprocating linear motion along the slide rail 11. The bracket 19 is also fixed on the bottom plate 2. The fixed track 8 for supporting the product 17 is fixed on the upper part of the bracket 19. The rotating shaft 3 is fixed on the bottom plate 2, and the rotating connecting plate 10 can rotate around the rotating shaft 3. The cam follower 14 and the rotating track 9 are also fixed on the rotating connecting plate 10. There is a chute on the rotating track 9, and the second slider 7 can slide up and down along it. The chute 18 is fixed on the second slider 7. The third cylinder 15 is fixed on the chute 18 and has a groove feature, and the slider 5 can slide left and right along it. There are many grooves on the slider 5, and the floating pressing plate 16 can slide along its chute. Three identical pressing plates 6 are also fixed on the slider 5, so that the floating pressing plate 16 is always in the extended state. When it is necessary to clamp the product 17, the third cylinder 15 contracts, driving the slider 5 and all its accessories above it to move to the right. Then the cylinder 4 contracts downward, driving the second slider 7 to slide downward on the bracket 19. Since the first slider 5 is installed on the second slider 7 and the third cylinder 15 is installed below the first slider 5, the floating pressing plate 16 is installed at the other end of the first slider 5, and the chute 18 is arranged below the first slider 5. Therefore, when the second slider 7 moves downward, it will drive the first slider 5 and other accessories to move downward at the same time. Finally, the floating pressing plate 16 presses the product 17. Because the floating pressing plate 16 can slide, the product 17 will not be damaged.

[0032] When it is necessary to flip the clamped product 17, the cylinder 1 extends, driving the U-shaped plate 13 to move forward, and then driving the cam follower 14 in the card slot to move forward. Since the cam follower 14 is fixed on the rotating connecting plate 10, the rotating connecting plate 10, the rotating track 9 and their associated components rotate together. Since it is easy for the rotating parts at both ends of the rotating shaft 3 to get stuck during frequent flipping, the oil storage tank 22 needs to be connected to the rotating shaft 3 by the connecting sleeve 20. The connecting sleeve 20 is fixed on the rotating shaft 3 by the buckle 21 below the connecting sleeve 20. Then the valve 25 is opened, and the oil outlets 23 connected to both sides of the oil storage tank 22 are used to discharge oil under the atmospheric pressure, so that the two ends of the rotating shaft 3 can be lubricated. The content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
