Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to a mechanically controlled automatic unloading manipulator. Background Art

[0002] The mechanically controlled unloading manipulator has a strong and flexible arm and gripping device that can adapt to materials of different shapes and weights. The precise transmission mechanism ensures the accuracy and repeatability of the action.

[0003] In the automotive manufacturing industry, this type of robot can quickly and accurately grab parts and unload them, helping to ensure efficient operation of the automotive production line; in the field of electronic manufacturing, it can accurately carry electronic components for assembly, improving product quality and production speed. In short, mechanically controlled automatic unloading robots provide strong support for modern industrial automation production.

[0004] When the manipulator is clamping goods, such as when the jaws are moving to clamp metal goods, there is a clear problem of unstable clamping, which will cause the goods to move inside the jaws, and there is a risk of the goods falling and the paint on the surface of the goods being damaged. For example, when clamping a box, the jaws will squeeze the corners of the box, and then the corners of the box will be squeezed and deformed, making the box unsightly. In summary, when existing manipulators are clamping goods, there is a risk of damaging the goods. Utility Model Content

[0005] The purpose of the utility model is to provide a mechanically controlled automatic unloading manipulator to solve the above-mentioned deficiencies in the prior art.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] Please refer to 1-3, a mechanically controlled automatic unloading robot comprises: a fixed bracket 1, a clamping claw bracket 2 is fixedly connected to the bottom of the fixed bracket 1, an electric telescopic rod 3 is fixedly installed in the fixed bracket 1, the output end of the electric telescopic rod 3 passes through the clamping claw bracket 2, and two connecting rods 7 are rotatably arranged on the output end of the electric telescopic rod 3, two symmetrically arranged clamping claws 5 are rotatably arranged in the clamping claw bracket 2, and the other ends of the two connecting rods 7 are rotatably arranged on one clamping claw 5 respectively, a slide groove 53 is opened in the clamping claw 5, and an anti-sliding block is slidably arranged in the slide groove 53.

[0025] Specifically, the utility model uses the telescopic effect of the output end of the electric telescopic rod 3 to make the two clamping claws 5 approach or move away from each other, so as to achieve the clamping and putting down of the goods. When the goods are clamped, the corners of the goods are dragged by the anti-sliding block. The elasticity of the protective block is used to prevent the goods from being easily deformed when subjected to the clamping force. As the clamping force increases, the anti-sliding block will slide upward in the slide groove 53 until the two sides of the goods are clamped by the side surfaces of the two clamping claws 5 and then stop. In this process, the clamping force of the two clamping claws 5 is converted into a force to lift the goods upward, thereby preventing the corners of the goods from being damaged by clamping with too much force.

[0026] In this utility model, reference is made to Figure 1The two connecting rods 7 are rotatably arranged on both sides of the output end of the electric telescopic rod 3 and are arranged symmetrically, and the other end of the connecting rod 7 is rotatably arranged on the clamping claw 5, so that the angle between the connecting rod 7 and the output end of the electric telescopic rod 3 and the angle between the connecting rod 7 and the clamping claw 5 can be changed. When the output end of the electric telescopic rod 3 moves upward, the connecting rod 7 will pull the clamping claw 5 to rotate inward, and then the two clamping claws 5 will clamp the goods in the middle. Conversely, when the output end of the electric telescopic rod 3 moves downward, the connecting rod 7 will push the clamping claw 5 to rotate outward, and then the goods clamped by the two clamping claws 5 will be put down.

[0027] Furthermore, the anti-sliding block includes a sliding block 8, which is slidably set in a sliding groove 53. The sliding block 8 is detachably connected to a silicone pad 9 via a second screw 10. The silicone pad 9 is provided with a hexagonal groove 91. The second screw 10 locks the sliding block 8 and the silicone pad 9 in the hexagonal groove 91.

[0028] Specifically, refer to Figure 2 First, put the slider 8 into the slide groove 53 so that the slider 8 can slide in the slide groove 53, and then attach the silicone pad 9 to the surface of the slider 8, and lock the slider 8 to the silicone pad 9 through the second screw 10. After locking, the top of the second screw 10 is located in the silicone pad 9 to avoid direct contact between the edges of the goods and the second screw 10, ensuring that when clamping the goods, the clamping force of the two jaws 5 is converted into a force to lift the goods upward, thereby preventing the edges of the goods from being damaged by the larger clamping force.

[0029] Furthermore, a groove 51 is provided on the clamping jaw 5, an extrusion block 6 is fixedly connected in the groove 51, a screw sleeve 61 is threadedly connected to the top of the extrusion block 6, an anti-slip pad 62 is fixedly connected to the top of the screw sleeve 61, a plurality of threaded holes 52 are provided in the groove 51, a first screw 63 is threadedly connected in the threaded hole 52, and an end of the first screw 63 is threadedly connected to the extrusion block 6.

[0030] Specifically, first, according to the size of the cargo volume, the first screw 63 is screwed into the threaded hole 52 of a suitable height, and the extrusion block 6 is threadedly connected to the first screw 63, so as to complete the fixation of the extrusion block 6, and then the screw sleeve 61 is threadedly connected to the extrusion block 6, and then the anti-skid pad 62 is fixedly connected to the screw sleeve 61 by screws or adhesives. Finally, according to the clamping condition of the cargo, the distance between the anti-skid pad 62 and the extrusion block 6 is changed by loosening or tightening the screw sleeve 61, so as to achieve the purpose of stably clamping the cargo; reference Figures 1 to 3 When the two clamping jaws 5 squeeze the goods, the slider 8 slides in the slide groove 53, so that the goods are lifted. At the same time, the two clamping jaws 5 gradually approach each other until the anti-slip pad 62 is in close contact with the goods and generates a squeezing force. At this time, the goods are stably clamped by the two clamping jaws 5.

[0031] Furthermore, a flange 4 is fixedly connected to the top of the fixing bracket 1 .

[0032] Specifically, the flange 4 can be fixedly connected to the mechanical arm to form a mechanical arm, and according to preset programs and instructions, operations such as unloading, handling and placing can be automatically completed to improve production efficiency and quality.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
