Description

Technical Field

[0001] This utility model relates to the technical field of deburring devices, and in particular to an automatic deburring device for plastic parts. Background Technology

[0002] Plastics are polymers formed from monomers through addition or condensation polymerization. They possess moderate resistance to deformation, falling between fibers and rubber, and are commonly used in the automotive industry. Burrs are a prevalent problem in the production of automotive plastic parts. Burrs not only affect the appearance quality of plastic parts but can also lead to poor fit during subsequent assembly, even impacting the overall performance and lifespan of the product. Traditional manual deburring methods are inefficient, labor-intensive, and inconsistent in their results, failing to meet the demands of modern large-scale, high-precision plastic parts production. To improve deburring efficiency, deburring devices for plastic parts have emerged. Utilizing advanced automation technology and innovative design concepts, these devices offer a completely new solution to the deburring process, significantly improving production efficiency and product quality.

[0003] For example, a deburring device for plastic parts, disclosed in the prior art (CN221474610U), uses a support ring and pressure plates. By turning two extrusion screws, the two pressure plates are brought closer together to extrude and fix the plastic part. When the grinding assembly is performing grinding operations, the rotatability of the support ring and pressure plates allows the extruded and fixed plastic part to rotate laterally and on its own axis according to the grinding requirements. This allows for deburring of all four sides of the plastic part without disassembly, saving considerable time and improving work efficiency compared to multiple disassembly and assembly methods.

[0004] However, in actual use, traditional plastic deburring devices require frequent replacement of the plastic parts to be processed, making the operation process cumbersome and greatly limiting the improvement of processing efficiency. Furthermore, some plastic parts are prone to having burrs remaining on their surface after processing. If these burr-bearing plastic parts are mixed with burr-free finished products, it will seriously affect the overall quality of the plastic parts, forcing workers to perform additional screening work and reducing the overall processing efficiency of plastic parts. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides the following technical solution:

[0006] An automatic deburring device for plastic parts includes a processing table, a feeding mechanism, and a deburring mechanism. The feeding mechanism includes a belt conveyor with multiple equally spaced partitions fixed on it. Plastic parts are placed between two adjacent partitions. The deburring mechanism includes mounting frames installed on both sides of the top of the processing table. A drive wheel and a driven wheel are fixed inside the mounting frames. An abrasive belt for deburring the plastic parts is connected between the drive wheel and the driven wheel. Both mounting frames are equipped with detection devices for scanning and inspecting the surface of the plastic parts.

[0007] Furthermore, a motor is fixedly installed on the top of each of the two mounting frames. The bottom end of the motor output shaft passes through the mounting frame and is fixed to the top of the drive wheel. The motor drives the drive wheel to rotate, thereby driving the sanding belt to rotate. The sanding belt can remove burrs from the surface of the two side walls of the plastic part.

[0008] Furthermore, the detection device includes an industrial camera, and both mounting frames have round holes machined on their outer walls. The industrial camera can be detachably installed in the round holes, making it convenient for workers to disassemble the industrial camera for maintenance and replacement.

[0009] Furthermore, both mounting frames are equipped with fixed lighting fixtures on their inner walls, positioned above the industrial camera. These fixtures illuminate the sidewalls of the plastic parts, thereby improving the clarity of the images captured by the industrial camera and ultimately enhancing the inspection accuracy.

[0010] Furthermore, a feeding structure and a guide plate are fixedly installed on both sides of the top of the processing table. The feeding structure includes an electric push rod installed on the top of the processing table. A push plate is fixed on the piston rod of the electric push rod. The electric push rod is extended to drive the push plate to move from left to right. The push plate pushes the plastic parts between the two partitions into the guide plate, so that the plastic parts slide down the guide plate and are easy for workers to collect.

[0011] Furthermore, a top plate is fixedly provided on the top of the processing table. The top plate is located in front of the push plate. Two electric push rods are fixedly passed through the top of the top plate. A pressure plate is fixedly provided at the bottom end of the piston rod of the two electric push rods. Multiple pressure rollers are fixedly provided at the bottom of the pressure plate to press on the top of the plastic part. The extension of the electric push rods drives the pressure rollers on the pressure plate to move down and press on the top of the plastic part, which can improve the stability of the plastic part during the deburring process of the sand belt.

[0012] Furthermore, a pad is fixedly provided inside the processing table. The pad is located inside the belt conveyor to support the plastic parts, thereby further improving the stability of the plastic parts during deburring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention enables the automatic conveying of plastic parts using a belt conveyor. During the conveying process, two rotating sanding belts automatically remove burrs from the sidewalls of the plastic parts. Simultaneously, an industrial camera monitors the burr condition on the sidewalls of the plastic parts in real time. When residual burrs are detected, an electric push rod drives a push plate to push the plastic part off the belt conveyor; conversely, the plastic part falls from the rear of the belt conveyor. This invention achieves automatic burr removal of plastic parts while also automatically screening qualified and unqualified plastic parts, greatly improving production efficiency.

[0025] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0026] Please see Figures 1-5This utility model provides an automatic deburring device for plastic parts, including a processing table 1, a feeding mechanism 2, and a deburring mechanism 3. The feeding mechanism 2 includes a belt conveyor 21 with multiple equally spaced partitions 22 fixedly mounted on it. Specifically, since the belt conveyor 21 consists of a conveyor belt, a drive device, and a support device, mounting multiple partitions 22 on the conveyor belt and placing the plastic parts between adjacent partitions 22 improves the stability during feeding. The deburring mechanism 3 includes mounting frames 31 mounted on both sides of the top of the processing table 1. A drive wheel 32 and a driven wheel 33 are fixedly mounted inside the mounting frames 31. A sanding belt 34 for deburring the plastic parts is connected between the drive wheel 32 and the driven wheel 33. A motor 36 is fixedly mounted on the top of each mounting frame 31. The bottom end of the output shaft of the motor 36 passes through the mounting frame 31 and is fixed to the top of the drive wheel 32. By driving the sanding belt 34 to rotate, the motor 36 can automatically remove burrs from the sidewall surface of the plastic parts.

[0027] Next, a detection device 35 for scanning and inspecting the surface of the plastic part is installed on each of the two mounting frames 31. Specifically, the detection device 35 includes an industrial camera 351, which can convert light signals into ordered electrical signals and provide clear and detailed images, thereby facilitating accurate detection and identification of details on the sidewall surface of the plastic part. Circular holes 352 are machined into the outer walls of both mounting frames 31, and the industrial camera 351 is detachably installed within these holes. Furthermore, an illumination lamp 353 is fixedly installed on the inner wall of each of the two mounting frames 31, positioned above the industrial camera 351 to illuminate the sidewall of the plastic part, thereby improving the clarity of the image captured by the industrial camera 351 and thus enhancing the detection accuracy.

[0028] Furthermore, a feeding structure 4 and a guide plate 5 are fixedly installed on both sides of the top of the processing table 1. The feeding structure 4 includes an electric push rod 41 installed on the top of the processing table 1, and a push plate 42 is fixedly installed on the piston rod of the electric push rod 41.

[0029] In actual use, the belt conveyor 21 is used to transport the plastic parts backward. When the plastic parts pass between the two sanding belts 34, the motor 36, drive wheel 32 and driven wheel 33 drive the sanding belts 34 to rotate. The two rotating sanding belts 34 can remove the burrs on the side wall surfaces of the plastic parts. Then the plastic parts are moved out from between the two sanding belts 34 and pass through the two industrial cameras 351. The two industrial cameras 351 use mechanical vision technology to process and capture images of the side wall of the plastic parts, so as to detect the burr situation on the side wall surface of the plastic parts. When burrs are detected on the side wall surface of the plastic parts, the electric push rod 41 extends and drives the push plate 42 to move from left to right, pushing the plastic parts off the belt conveyor 21. If no burrs are detected on the side wall surface of the plastic parts, the plastic parts fall from behind the belt conveyor 21, thus automatically completing the screening process of the plastic parts.

[0030] like Figures 1-3 As shown, a top plate 6 is also fixedly installed on the top of the processing table 1. The top plate 6 is located in front of the push plate 42. Two electric push rods 7 are fixedly inserted through the top of the top plate 6. A pressure plate 8 is fixedly installed at the bottom of the piston rod of the two electric push rods 7. Multiple pressure rollers 9 are fixedly installed at the bottom of the pressure plate 8 to press on the top of the plastic part. The pressure rollers 9 on the pressure plate 8 are driven to move down by the extension of the electric push rods 7 and press on the top of the plastic part, which can improve the stability of the plastic part during the deburring process of the sand belt 34.

[0031] Meanwhile, a pad 10 is fixedly installed inside the processing table 1. The pad 10 is located inside the belt conveyor 21. With the help of the pad 10, it can provide support on the inside of the conveyor belt at the bottom of the plastic part, thereby further improving the stability of the plastic part during deburring.

[0032] Furthermore, in actual use, a control box can be installed on the processing table 1 to control the operation of the belt conveyor 21, motor 36, industrial camera 351, lighting lamp 353, electric push rod 1 41, and electric push rod 2 7 of this utility model. The above technologies are all existing and commonly used technologies, and will not be described in detail here.

[0033] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
