Description

Technical Field

[0001] The present invention relates to the technical field of material transportation, and in particular to an anti-falling structure of a material box robot. Background Art

[0002] A material box robot is a robot used in logistics to carry material boxes. By clamping the material boxes on the shelf and moving them to the material box robot, the material box robot then drives the material box to move and carry. The material box robot can complete tasks such as carrying and stacking raw materials, realizing the automation and intelligence of the production process. However, during the transportation of the material box, it may fall due to looseness and slippage, so an anti-fall structure is required for protection and acceptance;

[0003] Since most of the existing material box robots use lifting and clamping methods to transport materials, and the main ropes used in the lifting process will shake, causing the transported materials to shake internally, it may cause damage to materials in the material box with large internal storage gaps, which has a certain adverse effect on actual use, and therefore needs to be improved. Summary of the invention

[0004] The purpose of the present invention is to provide an anti-falling structure for a material box robot, which has a driving conveying platform and a material box robot operating thereon that can move smoothly, and controls the clamping structure by the driving end on the clamping main frame to perform multi-sided and multi-point constraints on the material, and adds an anti-falling guardrail to adsorb the side of the material and support the bottom, which can achieve the anti-falling transportation effect advantage of the material box robot, bring certain favorable effects to actual use, and solve the problems raised in the above background technology.

On the surface of the lead screw, a moving nut seat is connected. On the side of the moving nut seat, a moving clamping frame is connected. On the surface of the clamping main frame near its side, a fixed clamping frame is fixedly connected. At the bottom of the moving clamping frame, a guiding component is connected. On the side of the clamping main frame, a magnetic attraction clamping seat is fixedly connected. On the surface of the magnetic attraction clamping seat, an alignment clamping frame is magnetically clamped. Inside the alignment clamping frame, a driving motor is fixedly installed. At the output end of the driving motor, a winding wheel frame is fixedly installed. On the surface of the winding wheel frame, a metal flexible rope is drivingly connected. One end of the metal flexible rope is fixedly connected to a bolt ring plate. On the surface of the bolt ring plate, a stabilizing frame is bolted. On the surface of the stabilizing frame, an anti-falling protection frame is fixedly installed.

[0006] Preferably, a side shifting frame is fixedly connected to the front side of the bin robot body. On the left side of the driving conveyor table, a distance sensor is fixedly installed, and the distance sensor is located on the left side of the side shifting frame.

[0007] Preferably, the main body of the disassembly and assembly positioning seat is a stabilizing seat. On the surface of the stabilizing seat, a locking component is connected. On the surface of the locking component, an extended bottom plate is connected. And on the surfaces of the extended bottom plate and the clamping main frame, the connecting screw is connected through an internal thread groove for positioning.

[0008] Preferably, the locking component includes a locking card plate and a locking card slot. The locking card plate is fixedly connected to the top of the extended bottom plate. The locking card slot is opened on the bottom of the stabilizing seat. The inner wall of the locking card slot and the surface of the locking card plate are clamped and adapted. Inside the locking card plate and inside the locking card slot, a locking screw is connected through an internal thread groove.

[0009] Preferably, the number of the clamping main frames is two, and the two clamping main frames are symmetrically connected to both sides of the disassembly and assembly positioning seat with the disassembly and assembly positioning seat as the axis of symmetry.

[0010] Preferably, the guiding component includes a guiding sliding plate and a guiding sliding groove. The guiding sliding plate is fixedly connected to the bottom of the moving clamping frame. The guiding sliding groove is opened on the surface of the clamping main frame. The inner wall of the guiding sliding groove and the surface of the guiding sliding plate are slidably connected.

[0011] Preferably, side plates are fixedly installed on the side surface of the movable clamping frame and the surface of the fixed clamping frame. An electric push rod is fixedly installed inside the side plate, and a lateral clamping frame is fixedly installed at the output end of the electric push rod.

[0012] Preferably, the main bodies of the movable clamping frame, the fixed clamping frame, and the lateral clamping frame are all rectangular frames. An electric cylinder is fixedly installed at the top of the rectangular frame, and a movable clamping plate is fixedly installed at the output end of the electric cylinder.

[0013] Preferably, the main body of the anti-falling protection frame is a fixing plate. The surface of the fixing plate is rotationally connected with a suction disc with a small air pump through a driving end. An arc-shaped supporting base plate is clamped inside the suction disc, and a wear-resistant coating is applied to the surface of the arc-shaped supporting base plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, the driving conveyor table is set as a basic transportation seat for the movement and adjustment of the loading box robot body thereon. The operation of the loading box robot body can control the rotation seat and the clamping main frame thereon to adjust the position, so that the clamping main frame can be adjusted to adapt to the clamping of batches of materials. Since the disassembly and assembly positioning seat is connected by a locking card plate and a locking slot, the position adjustment of different-width extension bottom plates thereon can be quickly carried out, and the reinforcement connection effect can be achieved through the locking screw. The clamping main frame can be connected and positioned on the side of the extension bottom plate. The clamping main frames in the left and right directions can maintain the clamping of the materials, and the main clamping structural parts on the loading box robot can be completed.

[0016] 2. In the present invention, the operation of the servo motor in the clamping main frame can drive the screw rod to rotate. The rotation of the screw rod guides the moving nut seat to move smoothly. The movable clamping frame can move smoothly under the guidance of the moving nut seat. With the function of the guiding slide plate and the guiding chute, the smooth movement of the movable clamping frame is guaranteed. And a lateral clamping frame is connected to the sides of the movable clamping frame and the fixed clamping frame. The operation of the electric push rod drives the lateral clamping frame to move smoothly. The operation of the electric cylinders in the lateral clamping frame, the fixed clamping frame, and the movable clamping frame can drive the movable clamping plate to move. The anti-slip sleeves on the movable clamping plate and the rectangular frame can be disassembled and assembled to adapt to the anti-slip clamping effect of the fitting constraint of the materials, forming a multi-sided up-and-down constraint effect of the materials in a double area, and the multi-sided and multi-point clamping protection effect of the materials can be realized during the transportation process.

[0017] 3. In the present invention, the magnetic adsorption card holder on the side of the clamping main frame can be used to connect the orientation adjustment card frame. The operation of the driving motor in the orientation adjustment card frame can drive the winding wheel frame to rotate, so as to wind and unwind the metal flexible rope for extension, so that the anti-falling protection frame on the subsequent stabilizing frame can be attached to the side of the material. The adsorption disc in the anti-falling protection frame can adsorb the side of the material, and the arc-shaped bottom support plate swings under the control of its driving end to support the bottom of the material, so as to achieve the effect of bottom support and anti-falling protection during the transportation of the material.
