Description

Technical Field

[0001] The present invention relates to the technical field of production line grasping, and in particular to a mechanical automation grasping device for a production line. Background Art

[0002] Automation refers to the process by which machinery and equipment achieve desired goals according to human requirements, with minimal or no human involvement. In automated production lines, gripping and handling are key components, crucial for improving production efficiency and reducing labor intensity. Therefore, reliable automated mechanical gripping devices are needed to meet production needs. However, existing automated mechanical gripping devices for assembly lines suffer from numerous issues. For example, most have a single gripping method, making it difficult to grip and handle products of varying shapes, sizes, and materials. This limits their scope of application and prevents them from adapting well to diverse production needs.

[0003] In the prior art, there is a mechanical automated grasping device for an assembly line, such as the one disclosed in Chinese Patent No. CN222405718U, which includes a support frame, a fixed plate fixedly connected to one side of the support frame, a movable assembly clamped on the top of the fixed plate, and a height adjustment assembly fixedly connected to the bottom of the movable assembly. The utility model is provided with a rotating motor and a fixed rod. When in use, the fixed rod is driven to rotate by the operation of the rotating motor. Since the fixed rod is connected to the clamping device, the angle at which the clamping device grasps the object can be adjusted. Then, by cooperating with the baffle, the connecting plate, the flat clamping plate, the rotating motor and the fixed rod, the object can be grasped from different directions. This avoids the situation where the surface of the grasped side of the object has a protrusion that is difficult to grasp, and the object is easily loosened and falls after grasping. If the grasping surface is not replaced, the object grasping efficiency is reduced, which is easy to cause loss.

[0004] Although the above patent can clamp objects, there are still some problems. The shape of the clamp of the device is fixed and it cannot clamp different objects well, so the clamping and carrying effect of the object will be reduced. At the same time, the device can only clamp objects from two directions, so the clamping effect may be reduced due to insufficient friction. For this reason, the present invention provides a mechanical automatic grasping device for a production line. Summary of the Invention

[0016] Beneficial effects The present invention provides a mechanical automated gripping device for a production line. Compared with the prior art, it has the following advantages: 1. The production line uses a mechanical automated grasping device. The first motor in the casing drives the first bidirectional screw to rotate, driving the two first connecting slides and the connected frames to move synchronously closer or farther in the horizontal direction, adjusting the distance between the two frames to accommodate workpieces of different widths.

[0017] The second motor on the frame drives the second bidirectional screw to rotate, causing the two second connecting sliders and the fixed clamping plate to slide along the limit rod to realize the opening and closing of the fixed clamping plate. The opening and closing of the fixed clamping plate is precisely to adapt to workpieces of different lengths so as to perform preliminary clamping of workpieces of different lengths; the first anti-slip rubber pad on the fixed clamping plate and the second anti-slip rubber pad on the rotating clamping plate enhance friction to prevent the workpiece from slipping.

[0018] The third motor on the vertical plate drives the second rotating rod to rotate, and drives the sliding bevel gear to rotate through the second spline. The sliding bevel gear engages with the rotating bevel gear, drives the first rotating rod and the rotating splint to rotate, and causes the rotating splint to flip relative to the fixed splint, thereby clamping the object from the side, forming a multi-directional clamping force, wherein the sliding bevel gear is connected to the fixed splint through the connecting plate, the first rotating rod is installed on the inner wall of the rotating frame, and the rotating frame is fixed to the outer wall of the fixed splint.

[0019] Through the combined design of the fixed splint and the rotating splint, the fixed splint can adapt to workpieces of different lengths and sizes by opening and closing, and the rotating splint can clamp the object from the side, which can achieve both plane clamping and multi-directional clamping, and can adapt to workpieces of different shapes and sizes, solving the problem of the single grasping method of traditional devices. The first anti-slip rubber pad and the second anti-slip rubber pad increase the friction force, and the multi-directional clamping structure composed of the fixed splint and the rotating splint prevents the workpiece from falling due to insufficient force in a single direction, thereby reducing safety hazards; at the same time, the adjustment function of the first bidirectional screw and the second bidirectional screw can accurately adapt to workpieces of different specifications and improve the clamping accuracy.

[0020] 2. This production line utilizes a mechanically automated gripping device. The device uses an electric slide rail at the top of the bracket to drive the adjustment and gripping components horizontally. Combined with a recognition camera on the outer wall of the gripping component's housing, the device identifies the workpiece's position and completes preliminary positioning before gripping. Universal casters on the bottom of the base plate enable flexible movement of the entire device to adapt to different production scenarios. A servo motor drives the second synchronous pulley and rotating sleeve via a first synchronous pulley and a synchronous belt. The rotating sleeve's inner wall engages with the first spline on the outer wall of the lifting column, driving the lifting column to rotate synchronously, achieving horizontal angle adjustment of the gripping component. Simultaneously, an electric push rod on the mounting frame pushes the lifting column along the inner wall of the rotating sleeve to adjust the height of the gripping component, ensuring precise alignment with the workpiece. The rotating sleeve and lifting column in the adjustment component achieve horizontal rotation and height adjustment of the gripping component. The electric slide rail achieves horizontal movement. Combined with the overall movement of the universal casters, the device can flexibly adjust the gripping position in complex production environments and adapt to the diverse layouts of the assembly line.

The outer walls of the fixed splint 412 and the rotating splint 414 are respectively fixedly installed with a first anti-slip rubber pad 413 and a second anti-slip rubber pad 415. The setting of the anti-slip rubber pad can increase the friction for grasping the workpiece.

[0031] Two vertical plates 421 are fixedly installed on the top of the frame 47, and a second rotating rod 422 is rotatably installed between the opposite sides of the two vertical plates 421. Two second splines 424 are fixedly installed on the outer wall of the second rotating rod 422. A third motor 423 is fixedly installed on the outer wall of one of the two vertical plates 421.

The third motor 423 can drive the second rotating rod 422 to rotate.

[0032] The outer wall of the second rotating rod 422 and the two second splines 424 is slidingly provided with a sliding bevel gear 419, and the outer wall of the sliding bevel gear 419 is rotatably connected with a connecting plate 420.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] When working, the device is first moved to the vicinity of the production line that needs to be grasped. The device drives the adjustment component 3 and the clamping component 4 to move horizontally through the electric slide rail 2 at the top of the bracket 1. Combined with the recognition camera 46 on the outer wall of the casing 41 in the clamping component 4, the position of the workpiece is recognized to complete the preliminary positioning before grasping. The recognition camera 46 cooperates with the controller 5 to realize automatic positioning and action coordination, reduce manual intervention, improve grasping efficiency, and meet the efficient production needs of the automated production line. The servo motor 33 drives the second synchronous wheel 37 and the rotating sleeve 38 to rotate through the first synchronous wheel 32 and the synchronous belt 34. The rotating sleeve 38 cooperates with the first spline 310 on the outer wall of the lifting column 39 through the inner wall, driving the lifting column 39 to rotate synchronously, thereby realizing horizontal angle adjustment of the clamping assembly 4; at the same time, the electric push rod 36 on the mounting frame 35 pushes the lifting column 39 to slide along the inner wall of the rotating sleeve 38 to complete the height adjustment of the clamping assembly 4 to ensure precise alignment of the workpiece. The rotating sleeve 38, the lifting column 39, etc. in the adjustment assembly 3 realize the horizontal angle rotation and height lifting of the clamping assembly 4, and the electric slide rail 2 realizes horizontal movement. Combined with the overall movement of the universal wheel 7, the device can flexibly adjust the grasping position in a complex production environment and adapt to the diversified layout of the assembly line. The first motor 42 in the casing 41 drives the first bidirectional screw 43 to rotate, driving the two first connecting sliders 45 and the connected frames 47 to synchronously approach or move away in the horizontal direction, adjusting the distance between the two frames 47 to adapt to workpieces of different widths.

[0036] The second motor 410 on the frame 47 drives the second bidirectional screw 48 to rotate, causing the two second connecting sliders 411 and the fixed clamping plate 412 to slide along the limit rod 49 to realize the opening and closing of the fixed clamping plate 412. The opening and closing of the fixed clamping plate 412 is precisely to adapt to workpieces of different lengths so as to perform preliminary clamping of workpieces of different lengths; the first anti-slip rubber pad 413 on the fixed clamping plate 412 and the second anti-slip rubber pad 415 on the rotating clamping plate 414 enhance friction to prevent the workpiece from slipping. The third motor 423 on the vertical plate 421 drives the second rotating rod 422 to rotate, and drives the sliding bevel gear 419 to rotate through the second spline 424. The sliding bevel gear 419 engages with the rotating bevel gear 418, driving the first rotating rod 417 and the rotating clamping plate 414 to rotate, so that the rotating clamping plate 414 flips relative to the fixed clamping plate 412, thereby clamping the object from the side, forming a multi-directional clamping force, wherein the sliding bevel gear 419 is connected to the fixed clamping plate 412 through the connecting plate 420, and the first rotating rod 417 is installed on the inner wall of the rotating frame 416, and the rotating frame 416 is fixed to the outer wall of the fixed clamping plate 412. Through the combined design of the fixed clamping plate 412 and the rotating clamping plate 414, the fixed clamping plate 412 can adapt to workpieces of different lengths and sizes by opening and closing, and the rotating clamping plate 414 can clamp the object from the side, which can achieve both planar clamping and multi-directional clamping, and can adapt to workpieces of different shapes and sizes, solving the problem of the single grasping method of the traditional device. The first anti-slip rubber pad 413 and the second anti-slip rubber pad 415 increase the friction force, and the multi-directional clamping structure composed of the fixed clamping plate 412 and the rotating clamping plate 414 prevents the workpiece from falling due to insufficient force in a single direction, thereby reducing safety hazards; at the same time, the adjustment function of the first bidirectional screw 43 and the second bidirectional screw 48 can accurately adapt to workpieces of different specifications and improve the clamping accuracy.
