Description

Technical Field

[0001] This utility model relates to the field of plastic parts technology, specifically to plastic parts conveying and deburring equipment. Background Technology

[0002] Injection molded parts are manufactured through injection molding and contain several holes with irregular contours. During the injection molding process, factors such as insufficient precision of the injection mold, inaccurate pressure and temperature control of the injection molding machine, instability of parameters such as pressure, temperature, and speed during injection, and insufficient operator skill can all lead to residual burrs on the edges, raised areas, and inside the holes. The conventional method of deburring is to manually scrape off the burrs using tools. This method is inefficient and relies heavily on manual labor; therefore, deburring equipment has been developed.

[0003] Chinese patent discloses a flow-type deburring device for injection molded parts (authorization announcement number CN 219095675U). This patented technology uses a flow-type integrated device, with a limiting plate and a scraper to complete the positioning of the injection molded parts to be processed, and a fixed scraper to complete the batch deburring. It solves the problems of low efficiency and poor consistency in traditional deburring work mentioned in the background technology. However, it cannot effectively remove residual deburrs on the edge contour, protrusions, and inside holes of injection molded parts. Utility Model Content

[0024] Please see Figures 1-9 In this embodiment of the utility model, the plastic part conveying and burr milling equipment includes a machine platform 1 and a robotic arm 2 located on one side of the machine platform 1. A set of transmission mechanisms 3 are installed on the machine platform 1. A baffle 4 is installed on the outer side of the set of transmission mechanisms 3. The baffle 4 divides each transmission mechanism 3 into two parts: one part is the feeding area and the other part is the milling area, thereby ensuring that feeding and milling do not interfere with each other.

[0025] exist Figure 2 , Figure 3 and Figure 9In this system, each conveying mechanism 3 includes a frame 32 and a conveyor belt 31 installed inside the frame 32. A discharge cavity frame 33 is installed on one side of the upper end of the frame 32, and guide plates 34 are respectively provided on the front and rear sides of the upper end of the frame 32 near the conveyor belt 31. The inner contour of the discharge cavity frame 33 is the same as the outer contour of the discharge cavity frame 33, thereby ensuring that the plastic part 5 can be accurately placed on the conveyor belt 31 and avoiding misplacement; the guide plates 34 can ensure that the plastic part 5 is accurately placed when placed on the conveyor belt 31. The plastic part 5 is conveyed on the conveyor belt 31 without shifting its position. A pushing mechanism 39 is installed on the front side of the upper end of the frame 32 away from the discharge cavity frame 33. An operating table 301 and a stop bar 38 are respectively installed on the rear side of the upper end of the frame 32 away from the discharge cavity frame 33. A limit cylinder 30 is installed on the front side of the upper end of the frame 32 near the guide plate 34. Laser sensors 302 are installed on both the front and rear sides of the upper end of the frame 32 near the limit cylinder 30. When the laser sensor 302 detects that the previous plastic part 5 has been conveyed to a position close to the pusher mechanism 39, the limiting cylinder 30 extends to limit and block the next plastic part 5; while the previous plastic part 5 continues to be conveyed and is limited and blocked by the baffle rod 38; then the pusher mechanism 39 pushes the plastic part 5 onto the operating table 301; one end of the operating table 301 is fixedly connected to the unloading channel 303, and the other end of the operating table 301 is fixedly connected to the unloading cylinder 35. A clamping mechanism 36 is installed at the rear end of the operating table 301, and an inner hole trimming assembly 37 is installed at the lower end of the operating table 301. When the plastic part 5 is located on the operating table 301, the clamping mechanism 36 presses the plastic part 5 to keep it fixed, and the robotic arm 2 and the inner hole trimming assembly 37 mill it. When the clamping mechanism 36 releases the plastic part 5, the milled plastic part 5 can be pushed into the unloading channel 303 by the unloading cylinder 35 and slide down automatically.

[0026] exist Figure 2 , Figure 3 , Figure 4 and Figure 9 In the middle, the pushing mechanism 39 includes a pushing cylinder 391, the output end of the pushing cylinder 391 is fixedly connected to a pushing head 393, and a cylinder frame 392 is fixedly connected to the lower end of the pushing cylinder 391. The cylinder frame 392 is fixed on the frame 32. By extending the cylinder frame 392, the pushing head 393 is driven to move, and the plastic part 5 can be pushed into the operating table 301 through the pushing head 393.

[0027] exist Figure 2 , Figure 2 , Figure 5 and Figure 9In the middle, the clamping mechanism 36 includes a clamping cylinder 361. The output end of the clamping cylinder 361 is fixedly connected to a connecting rod 363. One end of the connecting rod 363 is fixedly connected to a clamping head 362. By retracting the clamping cylinder 361, the connecting rod 363 and the clamping head 362 move downward together, and the clamping head 362 clamps the plastic part 5 onto the operating table 301.

[0028] exist Figure 3 , Figure 6 , Figure 7 and Figure 9 In the process, the inner hole trimming assembly 37 includes a trimming cylinder 371. A cylinder connecting frame 372 is fixedly connected to the outer side of the lower end of the trimming cylinder 371, and a cutting plate 373 is fixedly connected to the output end of the trimming cylinder 371. Several cutting blades 374 are provided on the cutting plate 373, and a V-shaped cutting head 375 is provided at the upper end of each cutting blade 374. Holes matching the cutting blades 374 are opened on the operating table 301, and the holes on the operating table 301 match the holes on the plastic part 5. By extending the trimming cylinder 371, the cutting plate 373 and the cutting blades 374 move upward together and sequentially pass through the holes on the operating table 301 and the holes on the plastic part 5 to remove the burrs on the inner wall of the holes on the plastic part 5. The V-shaped cutting head 375 can increase the cutting force on the burrs, making it easier to remove the burrs.

[0029] exist Figure 1 , Figure 8 and Figure 9 In the process, the output end of the robotic arm 2 is equipped with a milling cutter 21. The robotic arm 2 moves the milling cutter 21 to a position close to the plastic part 5, and the milling cutter 21 is used to mill the burrs on the contour position of the plastic part 5.

[0030] The working principle of this utility model is as follows: First, the conveyor belt 31 is started, and the plastic parts 5 to be milled are placed one by one from the feeding cavity frame 33 onto the conveyor belt 31 by manual or other means; then the plastic parts 5 are conveyed sequentially to the pushing mechanism 39 by the conveyor belt 31.

[0031] When the laser sensor 302 detects that the previous plastic part 5 has been conveyed to a position close to the pusher mechanism 39, the limit cylinder 30 extends to limit and block the next plastic part 5; while the previous plastic part 5 continues to be conveyed and is limited and blocked by the baffle rod 38; then the pusher mechanism 39 pushes the plastic part 5 onto the operating table 301.

[0032] Next, the plastic part 5 is pressed down by the clamping mechanism 36; then the milling cutter 21 is moved to a position close to the plastic part 5 by the robotic arm 2, and the milling cutter 21 is used to mill the burrs on the contour position of the plastic part 5; at the same time, the inner hole cutting assembly 37 extends to cut off the burrs on the inner wall of the hole on the plastic part 5.

[0033] Next, the clamping mechanism 36 retracts upward, releasing the plastic part 5. The unloading cylinder 35 extends, pushing the milled plastic part 5 into the unloading channel 303, and it slides down automatically.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
