Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, and in particular to a workshop goods gripping robot. Background Technology

[0002] With the rapid development and continuous innovation of technology, various industrial robots are integrating into daily production at an unprecedented pace. Industrial robots, with their superior work efficiency, excellent safety performance, low operating costs, and ultra-high production precision, have become an indispensable key force in modern industrial production. In production practice, the cargo gripping devices equipped on industrial robots play a crucial role, accurately and efficiently completing the tasks of gripping and transporting goods, greatly improving the automation and intelligence level of the production process.

[0003] For example, Chinese Patent CN220534241U discloses a cargo gripping device for industrial robots. The device describes a method where "a cylinder drives a first I-beam connecting plate to slide up and down within a groove. Because the length of the first I-beam connecting plate is fixed, when the first I-beam connecting plate slides upward, the two gripping members approach and clamp together; when the first I-beam connecting plate slides downward, the two gripping members move away and release, thus achieving identical movement speeds for both grippers and improving cargo handling efficiency." However, given that the gripping surfaces of the gripping members are planar, this device employs a planar gripping method. When using this device to grip goods with curved surfaces, it is difficult to maintain a stable gripping state, which greatly limits the applicability of this device. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a workshop goods gripping robot, comprising a base, a rotating disk mounted on the upper end of the base, a lifting mechanism mounted on the upper end of the rotating disk, a telescopic mechanism fixedly connected to the lifting end of the lifting mechanism, and a clamping mechanism fixedly connected to the telescopic end of the telescopic mechanism; the clamping mechanism comprises a drive assembly, a switching assembly, a V-shaped plate, and a straight plate; the drive assembly is fixedly connected to the telescopic end of the telescopic mechanism; a switching assembly is fixedly connected to both moving ends of the drive assembly; a straight plate and a V-shaped plate are fixedly connected to the rotating end of the switching assembly; and anti-slip rubber pads are provided on the clamping surfaces of the straight plate and the V-shaped plate.

[0005] As an improvement to the above technical solution, the driving assembly includes a U-shaped plate, a second motor, a bidirectional lead screw, a guide rod, and a moving block. The telescopic end of the telescopic mechanism is fixedly connected to the U-shaped plate. The second motor is mounted on the surface of the U-shaped plate. The output end of the second motor passes through a shaft hole opened on the surface of the U-shaped plate and is fixedly connected to the bidirectional lead screw. One end of the bidirectional lead screw is rotatably connected to the U-shaped plate. A guide rod is fixedly connected inside the U-shaped plate. Two moving blocks are threadedly connected to the surface of the bidirectional lead screw. The guide rod passes through the moving blocks and is slidably connected to them.

[0006] As an improvement to the above technical solution, the switching component includes a fixed block, a rotating block, a limiting rod, and a spring. The lower end of the moving block is fixedly connected to the fixed block, and the lower end of the fixed block is rotatably connected to the rotating block. Two limiting grooves are symmetrically opened at the lower end of the fixed block. A limiting rod is slidably connected through the rotating block, and the upper end of the limiting rod extends into the interior of the limiting groove. A spring is wound around the surface of the limiting rod, the upper end of the spring is fixedly connected to the rotating block, and the lower end of the spring is fixedly connected to the handle of the limiting rod.

[0007] As an improvement to the above technical solution, the lifting mechanism includes a vertical beam, a slider, a motor, and a lead screw. The upper end of the rotating disk is equipped with a vertical beam, and the slider is slidably connected to the vertical beam through a groove on its surface. The upper end of the vertical beam is equipped with a motor, the output end of which passes through the vertical beam and is rotatably connected to the vertical beam. The output end of the motor is fixedly connected to a lead screw, the lower end of which is rotatably connected to the vertical beam. The lead screw passes through the slider and is threadedly connected to the slider.

[0008] As an improvement to the above technical solution, the telescopic mechanism includes a slide rail, a cylinder, and a slide plate. One end of the slider is fixedly connected to the slide rail, and a slide plate is slidably arranged inside the slide rail. A cylinder is installed inside the slide rail, and the telescopic end of the cylinder is connected to the slide plate.

[0009] The beneficial effects of this utility model are: users only need to adjust the rotating end of the switching component to allow the V-shaped plate or straight plate to be accurately positioned at the clamping station, thereby achieving stable clamping of curved or flat objects. This gives the device extremely high flexibility, enabling it to easily handle the clamping and transfer tasks of curved or flat objects, greatly expanding its application scenarios and scope of application.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a workshop goods gripping robot, including a base 1, a rotating disk 2 installed on the upper end of the base 1, a lifting mechanism 3 installed on the upper end of the rotating disk 2, a telescopic mechanism 4 fixedly connected to the lifting end of the lifting mechanism 3, and a clamping mechanism 5 fixedly connected to the telescopic end of the telescopic mechanism 4; the clamping mechanism 5 includes a drive component 51, a switching component 52, a V-shaped plate 53, and a straight plate 54, the telescopic end of the telescopic mechanism 4 is fixedly connected to the drive component 51, the two moving ends of the drive component 51 are fixedly connected to the switching component 52, the rotating end of the switching component 52 is fixedly connected to the straight plate 54 and the V-shaped plate 53, and the clamping surfaces of the straight plate 54 and the V-shaped plate 53 are provided with anti-slip rubber pads 55.

[0017] In this implementation scheme, when operating, the user first needs to rotate the rotating ends of the two switching components 52, thereby causing the straight plate 54 and the V-shaped plate 53 to rotate. This allows for flexible adjustment of the relative positions between the straight plate 54 and the V-shaped plate 53, ensuring that the two straight plates 54 or the two V-shaped plates 53 can accurately correspond. Specifically, when facing the need to clamp a flat object, the user should adjust the two straight plates 54 to correspond; when clamping a curved object, the user should adjust the two V-shaped plates 53 to correspond. Subsequently, through the coordinated operation of the rotating disk 2, the lifting mechanism 3, and the telescopic mechanism 4, the clamping mechanism 5 is driven to smoothly approach the object to be clamped. At this time, the clamping mechanism 5, through the driving component 51, causes the two V-shaped plates 53 or straight plates 54 in the clamping position to move closer to each other, thereby achieving a stable clamping of the curved or flat object. This design enables the device to flexibly cope with the clamping and transfer needs of curved or flat objects, significantly expanding its adaptability.

[0018] like Figure 3 As shown, the drive assembly 51 includes a U-shaped plate 511, a second motor 512, a bidirectional lead screw 513, a guide rod 514, and a moving block 515. The telescopic end of the telescopic mechanism 4 is fixedly connected to the U-shaped plate 511. The second motor 512 is mounted on the surface of the U-shaped plate 511. The output end of the second motor 512 passes through the shaft hole opened on the surface of the U-shaped plate 511 and is fixedly connected to the bidirectional lead screw 513. One end of the bidirectional lead screw 513 is rotatably connected to the U-shaped plate 511. The guide rod 514 is fixedly connected inside the U-shaped plate 511. Two moving blocks 515 are threadedly connected to the surface of the bidirectional lead screw 513. The guide rod 514 passes through the moving blocks 515 and is slidably connected to the moving blocks 515.

[0019] In this embodiment, the user starts the second motor 512, which drives the bidirectional lead screw 513 to rotate, thereby causing the two moving blocks 515 to slide on the surface of the guide rod 514. The two moving blocks 515 move closer to each other, thereby causing the two switching components 52 to move closer to each other, and then causing the two V-shaped plates 53 or straight plates 54 in the clamping position to move closer to each other, thereby achieving stable clamping of curved or flat objects.

[0020] like Figure 4 As shown, the switching component 52 includes a fixed block 521, a rotating block 522, a limiting rod 524, and a spring 525. The lower end of the moving block 515 is fixedly connected to the fixed block 521, and the lower end of the fixed block 521 is rotatably connected to the rotating block 522. The lower end of the fixed block 521 has two symmetrically opened limiting grooves 523. The surface of the rotating block 522 is slidably connected to the limiting rod 524 that passes through it. The upper end of the limiting rod 524 extends into the interior of the limiting groove 523. The surface of the limiting rod 524 is wrapped with a spring 525. The upper end of the spring 525 is fixedly connected to the rotating block 522, and the lower end of the spring 525 is fixedly connected to the handle of the limiting rod 524.

[0021] In this embodiment, the user first stretches the limiting rod 524, causing the upper end of the limiting rod 524 to disengage from the limiting groove 523, thereby releasing the lock of the switching component 52. Then, the user rotates the rotating block 522, thereby causing the V-shaped plate 53 and the straight plate 54 to rotate, so that the V-shaped plate 53 or the straight plate 54 is in the clamping position. Then, the user releases the limiting rod 524, and under the elastic force of the spring 525, the limiting rod 524 is reinserted into the new limiting groove 523, thereby locking the switching component 52 after switching.

[0022] like Figure 2 As shown, the lifting mechanism 3 includes a vertical beam 31, a slider 32, a motor 33, and a lead screw 34. The vertical beam 31 is installed on the upper end of the rotating disk 2. The slider 32 is slidably connected to the vertical beam 31 through a groove on its surface. The motor 33 is installed on the upper end of the vertical beam 31. The output end of the motor 33 passes through the vertical beam 31 and is rotatably connected to the vertical beam 31. The output end of the motor 33 is fixedly connected to the lead screw 34. The lower end of the lead screw 34 is rotatably connected to the vertical beam 31. The lead screw 34 passes through the slider 32 and is threadedly connected to the slider 32.

[0023] In this embodiment, the user starts the motor 33, which drives the lead screw 34 to rotate, thereby causing the slider 32 to slide up and down inside the groove. Then, the telescopic mechanism 4 drives the clamping mechanism 5 to rise and fall, so as to facilitate the transfer of goods using the clamping mechanism 5.

[0024] like Figure 2 As shown, the telescopic mechanism 4 includes a slide rail 41, a cylinder 42, and a slide plate 43. One end of the slider 32 is fixedly connected to the slide rail 41. The slide plate 43 is slidably arranged inside the slide rail 41. The cylinder 42 is installed inside the slide rail 41. The telescopic end of the cylinder 42 is connected to the slide plate 43.

[0025] In this embodiment, the user activates the cylinder 42, which drives the slide plate 43 to slide inside the slide rail 41, thereby causing the clamping mechanism 5 to extend and retract, thus increasing the range of motion of the clamping mechanism 5 and improving its ability to transfer goods.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
