Description

Technical Field

[0001] This utility model relates to the field of bending unit flipping technology, and in particular to a vertical pneumatic flipping frame specifically for automatic bending units. Background Technology

[0002] The vertical pneumatic flipping frame fixture specifically designed for automated bending units is a fixed frame for a gripping device. When the robot needs to move the workpiece to a different position, the workpiece can be placed on the flipping frame and secured, allowing the robot to then grip the workpiece again in the new position.

[0003] Current robots re-grab sheet metal parts from the back to complete the flipping action. The gripper design needs to avoid interference with the flipping frame, which is quite difficult, especially for complex products and products with many varieties. This problem is particularly obvious, and it may even require the design of multiple flipping frames. Moreover, in real working conditions, the range of motion of each joint of the robot is limited. The ideal state is ±180 degrees, but many joints cannot achieve this. If flipping is required, the robot alone cannot complete the flipping action. Utility Model Content

[0004] The technical problem this invention aims to solve is that current flipping racks are expensive and their movement is easily restricted.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a vertical pneumatic flipping frame for automatic bending units, including a flipping support frame, on which 6 outwardly extending support rods are fixed, and 6 suction cups are installed on the support rods through 6 suction cup brackets. 90° air pipe connectors are installed on the suction cups. A pressure regulating filter with straight air pipe connectors on both sides is assembled at the lower end of the side wall of the flipping support frame. A plurality of vacuum generators and a plurality of pressure gauges are installed on the side wall of the flipping support frame above the pressure regulating filter. Solenoid valves are fixedly installed at the bottom connection end of each vacuum generator.

[0006] Four T-shaped three-way valves are fixed to the side wall of the flipping support frame by screws.

[0007] An inclined support frame is welded and fixed to the side wall of the flipping support frame.

[0008] The lower end of each support rod is fixed with a triangular reinforcing rib at the connection end of the flipping support frame.

[0009] Both the flipping support frame and the inclined support frame have bottom mounting bases welded and fixed to their bottoms.

[0010] The support rod has a lateral through hole on its side wall.

[0011] The beneficial effects of this utility model are:

[0012] (1) The present invention provides a vertical pneumatic flipping frame for automatic bending unit with 6 suction cups installed on the support rod, which are controlled by two solenoid valves respectively. The upper and lower suction cups are a group, and the middle four suction cups are a group. One or two groups of suction cups can be used according to the bending workpiece requirements, which is more flexible and has greater compatibility.

[0013] (2) Two sets of suction cups can be used for multiple bending workpieces, which can greatly reduce production costs;

[0014] (3) The entire flipping rack has a simple structure, utilizes the robot's working area space, does not require additional space, and occupies a small area;

[0015] (4) The horizontal support rod and suction cup design will not affect the movement of the robot and make it convenient to operate and use the robot. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Figure 2 This is a schematic diagram of the rear structure of this utility model. Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Figure 1 and Figure 2The vertical pneumatic flipping frame for automatic bending units shown includes a flipping support frame 1. Six outwardly extending support rods 2 are fixed on the flipping support frame 1. Six suction cups 4 are installed on the support rods 2 via six suction cup brackets 3. 90° air pipe connectors 5 are installed on the suction cups 4. Pressure regulating filters 7 with straight air pipe connectors 6 on both sides are assembled at the lower end of the side wall of the flipping support frame 1. Four vacuum generators 8 and two pressure gauges 9 are installed on the side wall of the flipping support frame 1 above the pressure regulating filters 7. Solenoid valves 10 are fixedly installed at the bottom connection end of each vacuum generator 8.

[0022] The suction cup 4, 90° air pipe connector 5, straight air pipe connector 6, pressure regulating filter 7, vacuum generator 8, pressure gauge 9, and solenoid valve 10 are connected by an air guide pipe. The vacuum generator draws air at the suction cup position, thereby achieving the adsorption effect.

[0023] To facilitate the connection and flow guidance of the trachea, four T-shaped three-way valves 11 are fixed to the side wall of the flip support frame 1 by screws.

[0024] To accommodate the lateral support force, an inclined support frame 12 is welded and fixed to the side wall of the flipping support frame 1.

[0025] To enhance the structural strength of the support rod 2, triangular reinforcing ribs 13 are fixed at the lower end of the support rod 2 at the connection end of the flipping support frame 1.

[0026] To improve the structural stability of the entire flipping frame, both the flipping support frame 1 and the inclined support frame 12 are welded and fixed with bottom mounting bases 14.

[0027] The device is secured to the ground using the fixing bolts on the bottom mounting base 14.

[0028] To facilitate the insertion of the tube, a lateral tube insertion hole 15 is provided on the side wall of the support rod 2.

[0029] The robot moves to the flipping frame, places the sheet metal on it, releases the product, and avoids it. After flipping, the robot uses suction cups 4 to pick up the sheet metal. There are 6 suction cups 4 on the flipping frame, each controlled by two solenoid valves 10. The upper and lower suction cups 4 form one group, and the four suction cups 4 in the middle form another group. One or two groups of suction cups 4 are used depending on the bending requirements of the workpiece.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
