Description

Technical Field

[0001] The invention belongs to the field of automobile interior plastic part finishing, and in particular relates to a post-processing device for automobile interior plastic parts. Background Art

[0002] In modern automotive manufacturing, interior plastic parts, thanks to their lightweight, low cost, and flexible design, are widely used in instrument panels, door panel trims, air conditioning vents, and other components. As consumers' demands for aesthetics, comfort, and safety in automotive interiors continue to rise, the surface quality and assembly precision of interior plastic parts have become key indicators of vehicle quality. Therefore, the post-processing finishing of plastic parts is crucial for ensuring product quality.

[0003] The processing technology for automotive interior plastic parts primarily includes deburring, surface polishing, and dimensional correction. When polishing holes on the surface of interior plastic parts, a multi-axis robot with a polishing head is typically used to penetrate deep into the holes for polishing. However, the polishing heads of existing interior plastic polishing equipment have the following defects: 1) During the polishing process, friction between the polishing head and the inner surface of the interior plastic part's hole generates a significant amount of heat. This heat gradually increases the temperature of the polishing wheel over time, and subsequent continued contact with the inner surface of the interior plastic part's hole accelerates the temperature rise of the interior plastic part, potentially causing localized overheating and deformation of the interior plastic part, and even defects such as burning and partial discoloration.

[0004] 2) Existing polishing heads have a certain thickness, and the depth of the holes in interior plastic parts is usually shallow. When the polishing head is inserted into the hole of the interior plastic part and contacts the inner wall of the hole for polishing, the contact point between the polishing head and the inner wall of the hole of the interior plastic part is fixed, making it easier for heat to accumulate at the contact point of the polishing head, causing the temperature to rise rapidly, further increasing the risk of quality problems in the polishing of interior plastic parts.

[0005] Therefore, in order to solve the problem of excessive temperature of automobile interior plastic parts during the polishing process, the present invention provides an automobile interior plastic part post-processing equipment. Summary of the Invention

[0027] The following is combined with Figure 1 -Attached Figure 7 This application is described in further detail.

[0028] Please refer to Figure 1-Figure 3A post-processing device for interior plastic parts includes a multi-axis manipulator 1 and a polishing mechanism 2 mounted on the multi-axis manipulator 1. The polishing mechanism 2 includes a rotating assembly 21 connected to the multi-axis manipulator 1. The rotating assembly 21 is connected to a fixed seat 22, and a plurality of polishing assemblies 23 are arranged on the circumference of the fixed seat 22. The fixed seat 22 is driven to move by the multi-axis manipulator 1, so that the polishing assemblies 23 on the fixed seat 22 can be inserted into the inner wall of the hole of the interior plastic part for polishing. The rotating assembly 21 can also drive the fixed seat 22 to rotate, switching different polishing assemblies 23 to contact the inner wall of the hole of the interior plastic part for polishing. After working for a certain period of time, each polishing assembly 23 can be switched to an unloaded state for heat dissipation, thereby avoiding the adverse effects caused by the high temperature of the polishing assembly 23 itself causing a rapid temperature rise when contacting the inner ring of the interior plastic part.

[0029] See Figure 1-Figure 3 The rotating assembly 21 includes a connecting sleeve connected to the multi-axis manipulator 1, and a driving motor 1 (not shown in the figure) is fixedly installed inside the connecting sleeve. The output shaft of the driving motor 1 movably passes through the end face of the connecting sleeve and is fixedly connected to the fixed seat 22. The driving motor 1 drives the fixed seat 22 to rotate intermittently and periodically.

[0030] See Figure 4 and Figure 6 A heat dissipation cavity 221 is provided inside the fixed seat 22, and a plurality of rotation grooves are evenly provided on the circumferential side of the fixed seat 22 along its circumferential direction. The rotation grooves are connected to the heat dissipation cavity 221. A driving shaft 24 is rotatably provided between the upper and lower inner walls of the heat dissipation cavity 221. The polishing assembly 23 includes a driven shaft 231 rotatably provided in the rotation groove. A polishing head 232 is slidably sleeved on the driven shaft 231 and can slide up and down along its length. Part of the polishing head 232 protrudes from the outer wall of the circumferential side of the fixed seat 22.

[0031] See Figure 3 、 Figure 4 and Figure 7 A cooling assembly 25 is provided on the driving shaft 24. In this embodiment, a fan blade assembly is coaxially fixedly mounted on the lower end surface of the driving shaft 24. A driving assembly 1 26 for rotating the polishing head 232 is provided between the driving shaft 24 and the multiple driven shafts 231. A driving assembly 27 for driving the polishing head 232 to slide back and forth is provided between the fixed base 22 and the driving shaft 24.

[0032] During specific operation, the rotating component 21 periodically switches different polishing heads 232 to contact the inner ring of the interior plastic part for work, so that the idle polishing head 232 can dissipate heat naturally at no load. At the same time, the driving component 26 rotates to drive the polishing head 232 to rotate continuously at high speed. The part of the polishing head 232 exposed outside the fixed seat 22 can polish the interior plastic part. The position of the polishing head 232 close to the heat dissipation cavity 221 is cooled by the fan blade group selected by the active rotating shaft 24, which can dissipate heat for both the working polishing head 232 and the idle polishing head 232, and has a good heat dissipation effect.

[0033] In addition, the driving component 27 can cyclically control the polishing head 232 to move up and down along the corresponding driven shaft 231 during operation, which can not only eliminate the difference in polishing lines in the circumferential direction and improve the polishing quality, but also avoid the contact between a local single area of the polishing head 232 and the inner wall of the hole of the interior plastic part. The up and down movement causes the contact point to change dynamically, and the heat is dispersed with the movement, thereby avoiding the adverse effects of excessive temperature of the polishing head 232 on the holes of the interior plastic part, and further improving the polishing quality.

[0034] See Figure 4 A second drive motor is fixedly mounted inside the fixing base 22 at one end thereof close to the rotating assembly 21. The output shaft of the second drive motor movably extends into the heat dissipation cavity 221 and is fixedly connected to the upper end of the active rotating shaft 24. The second drive motor drives the active rotating shaft 24 to rotate.

[0035] See Figure 3 and Figure 7 The polishing head 232 consists of an I-shaped disc 2321 and a polishing wheel 2322 fixedly mounted on the surface of the I-shaped disc 2321. The middle section of the driven shaft 231 is rectangular, and multiple sets of vertically distributed ball bearings are rotatably mounted on the four sides of the rectangular section of the driven shaft 231. A rectangular sliding hole is formed between the upper and lower surfaces of the I-shaped disc 2321, and the ball bearings are in rolling contact with the inner walls of the corresponding sides of the rectangular sliding hole. The rotation of the driven shaft 231 drives the I-shaped disc 2321. Drive assembly 27 also allows the I-shaped disc 2321 to move up and down relative to the driven shaft 231. During this movement, the ball bearings reduce friction when the polishing head 232 moves up and down relative to the driven shaft 231.

[0036] See Figure 4 and Figure 6Drive assembly 1 26 includes a driving gear 1 261 coaxially fixedly mounted on the surface of the driving shaft 24. A driven gear 1 262 is coaxially fixedly mounted on the upper end of the driven shaft 231. The driving gear 1 261 and the driven gear 1 262 mesh with each other. Rotation of the driving shaft 24 drives the driving gear 1 261, causing multiple driven gears 1 262 around the circumference to rotate synchronously at high speed, thereby driving the corresponding driven shafts 231 to rotate at high speed, causing the polishing head 232 to rotate at high speed.

[0037] See Figure 3 、 Figure 4 and Figure 6 The second drive assembly 27 includes an ascending drive unit 271 disposed in the rotating groove and used to drive the polishing head 232 to ascend. The ascending drive unit 271 includes a rotating sleeve 2711 rotatably disposed on the lower inner wall of the rotating groove and coaxial with the corresponding driven rotating shaft 231. A driving seat 2712 is fixedly disposed on the upper end of the rotating sleeve 2711. The upper end surface of the driving seat 2712 is provided with a spiral lifting slope 3 and is circumferentially closed. A support column 2713 is fixedly disposed on the lower end edge of the I-shaped disk 2321. The lower end of the support column 2713 is rotatably provided with a second ball bearing. The second ball bearing is in rolling connection with the spiral lifting slope 3 on the upper side of the corresponding driving seat 2712. When the I-shaped disk 2321 rotates, the second ball bearing on the lower end of the support column 2713 can move along the spiral lifting slope 3 on the upper side of the driving seat 2712. During the movement, the support column 2713 can drive the I-shaped disk 2321 to rise and fall along the spiral lifting slope 3, thereby causing the polishing head 232 to move up and down.

[0038] See Figure 5-Figure 7 The inner edge is fixedly provided on the inner wall of the upper end of the heat dissipation cavity 221, and a downward driving part 272 for driving the polishing head 232 to move downward is provided on the inner edge. The downward driving part 272 corresponds to the upward driving part 271 one by one. The downward driving part 272 includes a connecting ring plate 2721 movably sleeved on the upper end surface of the driven rotating shaft 231 and located on the upper side of the inner edge. A plurality of guide rods 2722 are fixedly provided on the lower side of the connecting ring plate 2721 along its circumferential direction. The guide rods 2722 are connected to the polishing head 232. The inner edge is slidably connected, and a compression spring 2723 is fixedly mounted on the upper surface of the guide rod 2722 and the upper side of the inner edge. The compression spring 2723 is sleeved on the surface of the guide rod 2722, which is slidably connected to the inner edge. The lower ends of multiple adjacent guide rods 2722 are fixedly connected to a lower pressure ring plate 2724. The lower side of the lower pressure ring plate 2724 is rotatably provided with multiple evenly arranged ball bearings 3, which are in rolling contact with the upper surface of the corresponding I-shaped disk 2321. The lower pressure ring plate 2724 contacts the upper side of the I-shaped disk 2321 through the ball bearings 3, reducing friction during high-speed rotation. At the same time, the guide rod 2722 and the compression spring 2723 cooperate to ensure that the lower pressure ring plate 2724 continuously presses down on the I-shaped disk 2321, ensuring its smooth downward movement.

[0039] See Figure 4-Figure 6 The rotating sleeve 2711 and the active rotating shaft 24 are transmitted through the rotating driving part 273. The rotating driving part 273 includes a second driving gear 2731 coaxially fixedly sleeved on the surface of the active rotating shaft 24. A second driven gear 2732 is coaxially fixedly sleeved on the rotating sleeve 2711. The second driving gear 2731 is meshed with the second driven gear 2732, and the diameter of the first driving gear 261 is larger than that of the second driving gear 2731. In order to prevent the polishing head 232 from moving up and down along the corresponding driven shaft 231 at too fast a frequency, the driving shaft 24 rotates to drive the driving gear 1 261 to rotate, and at the same time, the driving gear 2 2731 can be driven to rotate in the same direction, so that the rotating sleeve 2711 can be sleeved on the surface of the corresponding driven shaft 231 and rotate in the same direction as the driven shaft 231, and the rotation speed of the rotating sleeve 2711 is slightly lower than that of the driven shaft 231, so that the rotation speed of the driving seat 2712 at the upper end of the rotating sleeve 2711 is slightly lower than that of the I-shaped disk 2321, so that the ball at the lower end of the corresponding support column 2713 can move along the spiral lifting slope 3 on the surface of the driving seat 2712, ensuring that the up and down movement speed of the I-shaped disk 2321 is not too fast.

[0040] The specific working process of this equipment is as follows: The multi-axis manipulator 1 inserts the fixed seat 22 into the hole (such as a circular or bar-shaped hole) of the interior plastic part to be polished. The drive motor 2 is activated to rotate the active shaft 24. The active shaft 24 rotates, and the drive assembly 1 26 and the drive assembly 27 are used to make all the polishing heads 232 rotate at high speed while cyclically moving up and down. At the same time, the fan blade assembly rotates at high speed to generate a cooling airflow that acts on the polishing wheel 2322 on the surface of each polishing head 232 to cool it. The multi-axis manipulator 1 controls any polishing head 232 on the side of the fixed seat 22 to contact the inner wall of the hole and move along a predetermined path for polishing. After a certain interval, the drive motor 1 drives the fixed seat 22 to rotate a certain angle to switch the polishing head 232.
