Description

Technical Field

[0001] This utility model relates to the field of robot assembly technology, and in particular to a material lifting device for robot assembly. Background Technology

[0002] In the robot assembly process, material lifting equipment is used to lift parts and other materials from a lower position to an operable assembly position, or to transport materials from one area to another, thereby achieving efficient material transfer and precise delivery, and improving assembly efficiency.

[0003] According to the patent document with publication number CN222453719U, the patent document describes a method where an electric push rod drives an adjusting arm to rotate, which in turn drives a right rotating rod to rotate. This, in turn, drives the right gripper arm to rotate the right gripper. Through the meshing of the right and left gears, the rotation of the right rotating rod simultaneously drives the left rotating rod to rotate, which in turn drives the left gripper arm to rotate the left gripper. This allows the right and left grippers to grip the materials used for robot assembly. A servo motor drives a threaded rod to move a threaded sleeve upward, which in turn lifts the right gripper, the left gripper, and the materials used for robot assembly as a whole. A stepper motor drives a transmission shaft to move a belt, which in turn moves the sliding frame synchronously, thus moving the gripped materials synchronously.

[0004] In the process of gripping materials for robot assembly by the right and left grippers, the patent document states that the shape and size of the right and left grippers are fixed, which cannot adapt to materials of different sizes. When the material size is too large, the right and left grippers cannot completely wrap the material. When the material size is too small, there are too few contact points between the right and left grippers and the material, which can easily cause the material to fall off, resulting in poor gripping effect. Utility Model Content

[0005] The purpose of this invention is to provide a material lifting device for robot assembly in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A material lifting device for robot assembly includes a support frame, a first slide plate slidably connected to the front side of the support frame, and an adjusting clamping mechanism located in front of the first slide plate.

[0008] The adjusting clamping mechanism includes a support plate, which is fixed to the front side of the first slide plate. Two second slide plates are slidably connected to the bottom of the front side of the support plate. The top of the two second slide plates is threadedly connected to a second lead screw. Six first clamping plates are fixed to the bottom of each of the two second slide plates. Each pair of first clamping plates forms a group. A second clamping plate is slidably connected between the two pairs of first clamping plates in each group. A connecting rod is provided at the bottom of each of the two second slide plates. The top of the three second clamping plates on the same side is fixedly connected to the connecting rod. The front and rear ends of the two connecting rods are hinged to the front and rear sides of the corresponding two second slide plates with hydraulic cylinders.

[0009] Preferably, the bottom of the support frame is fixed with a base frame, and the bottom of the base frame is fixed with casters at all four corners.

[0010] Preferably, a first lead screw is rotatably connected to the front side of the support frame, the first lead screw is threadedly connected to the middle of the first slide plate, and a first motor is fixedly installed at the input end of the first lead screw.

[0011] Preferably, the second lead screw is rotatably connected to the bottom of the front side of the support plate, and the input end of the second lead screw is fixedly equipped with a second motor.

[0012] Preferably, both the first clamping plate and the second clamping plate are banana-shaped and curved near the material side.

[0013] Preferably, all three sets of first clamping plates on the same side are slidably connected to the connecting rod.

[0014] Preferably, the first clamping plate has an arc-shaped groove for the connecting rod to pass through.

[0015] The beneficial effects compared with the existing technology are as follows: Four hydraulic cylinders drive the corresponding two connecting rods to slide along the arc groove of the first clamping plate, thereby adjusting the combined length of each set of first clamping plates and the corresponding second clamping plate to meet the clamping of materials of different heights. The second motor drives the second lead screw to move the two second slide plates closer or further apart, thereby adjusting the distance between the three sets of first clamping plates and the corresponding second clamping plates on both sides to meet the clamping of materials of different widths and improve the stability of clamping materials of different sizes.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8 As shown, a material lifting device for robot assembly includes a support frame 2, a first slide plate 3 slidably connected to the front side of the support frame 2, and an adjusting clamping mechanism 7 located in front of the first slide plate 3.

[0030] In this embodiment: the adjusting clamping mechanism 7 includes a support plate 701, which is fixed to the front side of the first slide plate 3. Two second slide plates 702 are slidably connected to the bottom of the front side of the support plate 701. The tops of the two second slide plates 702 are threadedly connected to a second lead screw 703, which is rotatably connected to the bottom of the front side of the support plate 701. A second motor 704 is fixedly installed at the input end of the second lead screw 703. Six first clamping plates 705 are fixed to the bottom of each of the two second slide plates 702. Each pair of first clamping plates 705 forms a group, and a second clamping plate 706 is slidably connected between each pair of first clamping plates 705. Both the first clamping plates 705 and the second clamping plates 706 are banana-shaped, curved near the material side. A connecting rod 707 is provided at the bottom of each of the two second slide plates 702. The tops of the three second clamping plates 706 on the same side are fixedly connected to the connecting rod 707. Each first clamping plate 705 is slidably connected to a connecting rod 707. The first clamping plate 705 has an arc-shaped slot for the connecting rod 707 to pass through. The front and rear ends of the two connecting rods 707 are hinged to the front and rear sides of the corresponding two second sliding plates 702. The four hydraulic cylinders 708 drive the corresponding two connecting rods 707 to slide along the arc-shaped slot of the first clamping plate 705, thereby driving the six corresponding second clamping plates 706 to slide out from the six sets of first clamping plates 705. This adjusts the combined length of each set of first clamping plates 705 and the corresponding second clamping plates 706 to meet the clamping requirements of materials of different heights. The second motor 704 drives the second lead screw 703 to move the two second sliding plates 702 closer or further apart, thereby adjusting the distance between the three sets of first clamping plates 705 and the corresponding second clamping plates 706 on both sides to meet the clamping requirements of materials of different widths.

[0031] In this embodiment: a base frame 1 is fixed to the bottom of the support frame 2, and casters 6 are fixed to the four corners of the bottom of the base frame 1. A first lead screw 4 is rotatably connected to the front side of the support frame 2. The first lead screw 4 is threadedly connected to the middle of the first slide plate 3. A first motor 5 is fixedly installed at the input end of the first lead screw 4. By pushing the support frame 2, the base frame 1 and the four casters 6 are moved, thereby realizing the movement of equipment and materials. The first motor 5 drives the first lead screw 4 to move the first slide plate 3 in the vertical direction, thereby driving the adjusting clamping mechanism 7 and the materials to move in the vertical direction.

[0032] Working principle: First, the adjusting clamping mechanism 7 is adjusted according to the height of the material. Four hydraulic cylinders 708 drive the corresponding two connecting rods 707 to slide along the arc groove of the first clamping plate 705, thereby driving the corresponding six second clamping plates 706 to slide out from the corresponding six sets of first clamping plates 705, thus adjusting the combined length of each set of first clamping plates 705 and corresponding second clamping plates 706. The second motor 704 drives the second lead screw 703 to drive the two second sliding plates 702 to move closer to each other, thereby driving the three sets of first clamping plates 705 and corresponding second clamping plates 706 on both sides to move closer to each other, thereby clamping the material. The first motor 5 drives the first lead screw 4 to drive the first sliding plate 3 to move upward in the vertical direction, thereby driving the adjusting clamping mechanism 7 and the material to move upward in the vertical direction, realizing the lifting of the material. This pushes the support frame 2 to drive the base frame 1 and four universal wheels 6 to move, thereby moving the equipment and material to the unloading point.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
