Description

Technical Field

[0001] The utility model relates to the technical field of relay housing processing, in particular to a plastic grabbing device. Background Art

[0002] A relay is an electrical control device that can give a specified input and maintain it for a long enough time, causing a predetermined step change in the controlled quantity in the electrical output circuit. When the input drops to a certain level and remains for a long enough time, it returns to its initial state.

[0003] Since the relay is composed of a plastic relay shell and electrical components, the plastic relay shell needs to be grasped by a grasping device during the production and processing, and the grasped plastic relay shell is moved to a processing table for processing. After the grasping device grasps the plastic relay shell, since the relay shell is plastic, excessive clamping force can easily cause the relay shell to crack. After reducing the clamping force on the relay shell, when the device rotates to change the position of the clamped relay shell, the rotation will cause shaking, causing the clamped relay shell to fall off. Utility Model Content

[0004] The utility model aims to provide a plastic grabbing device to solve the defect in the prior art that when the device rotates to change the position of the clamped relay housing, the rotation will cause shaking, thereby causing the clamped relay housing to fall off.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A plastic gripping device is designed, comprising a support frame, wherein:

[0007] The support frame is fixedly connected with a motor, the output end of the motor is fixedly connected with a top plate, the upper end of the top plate is fixedly connected with a first electric telescopic rod, the telescopic end of the first electric telescopic rod is fixedly connected with a fixing seat, the fixing seat is fixedly connected with an electric claw, and the top plate is fixedly connected with a limiting mechanism for preventing the relay housing from falling;

[0008] The limiting mechanism includes a first mounting plate, the first mounting plate is fixedly connected to the top plate, a second electric telescopic rod is fixedly connected to the first mounting plate, and a stopper is fixedly connected to the telescopic end of the second electric telescopic rod.

[0009] Preferably, an anti-corrosion layer is sprayed on the support frame.

[0010] Preferably, a guide rod is fixedly connected to the blocking member, and the guide rod passes through the first mounting plate.

[0011] Preferably, the baffle includes a connecting plate, which is fixedly connected to the telescopic end of the second electric telescopic rod and the guide rod, and a baffle is rotatably connected to one side of the connecting plate, and the bottom end of the baffle is fixedly connected to the second mounting plate, and a spring is fixedly connected to the second mounting plate, and one end of the spring is fixedly connected to the lower surface of the connecting plate.

[0012] Preferably, the baffle plate and the second mounting plate are an integral structure.

[0013] The utility model provides a plastic grabbing device, which has the following beneficial effects:

[0014] After the second electric telescopic rod is started, the blocker drives the blocker to move a set distance toward the electric claw. The blocker moves smoothly under the guidance of the guide rod. After the blocker moves a set distance toward the electric claw, it contacts the bottom end of the relay housing to support and limit the relay housing. During the rotational movement, the blocker supports and limits the relay housing, so that the relay housing on the electric claw will not fall off. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Working process: when grabbing the relay housing, the first electric telescopic rod 4 is powered on and started, driving the fixed seat 5 to move downward by a set distance, and the fixed seat 5 drives the electric claw 6 to move, and the relay housing is located below the electric claw 6. The electric claw 6 is powered on and started to grab the relay housing. After the relay housing is grabbed, the first electric telescopic rod 4 drives the electric claw 6 to move upward and reset through the fixed seat 5, and the second electric telescopic rod 72 is powered on and started. After the second electric telescopic rod 72 is started, it drives the stopper 73 to move toward the electric claw 6 by a set distance. The stopper 73 moves smoothly under the guidance of the guide rod 74. After the stopper 73 moves toward the electric claw 6 by a set distance, it contacts the bottom end of the relay housing, and supports and limits the relay housing.

[0025] After the motor 2 is started, it drives the top plate 3 to rotate, the top plate 3 drives the first electric telescopic rod 4 to rotate, the first electric telescopic rod 4 drives the electric claw 6 to rotate through the fixed seat 5, the electric claw 6 drives the relay housing to rotate, and moves the relay housing to the set position. During the rotation and movement, the stopper 73 supports and limits the relay housing, so that the relay housing on the electric claw 6 will not fall off.
