Description

Technical Field

[0001] This invention belongs to the technical field of automotive trim panel processing, specifically a trim panel shaping device for automotive trim panel processing. Background Technology

[0002] With the rapid development of the automotive industry, consumers are increasingly demanding higher quality from car interiors and exteriors. As a core component of the vehicle's exterior and interior experience, automotive trim panels directly impact the overall quality and market competitiveness of a car due to their molding precision, edge smoothness, and surface integrity. Automotive trim panels encompass various types, including door panels, dashboard panels, and pillar panels, and are primarily made of materials such as ABS, PP, PVC, and composite fibers. After molding processes like injection molding and vacuum forming, issues such as burrs, flash, dimensional deviations, and surface defects inevitably arise. Therefore, reshaping has become an indispensable and crucial step in the automotive trim panel production process.

[0003] Currently, most trimming devices used in automotive trim processing employ clamping fixtures to hold and fix the trim panels before trimming. When using clamping fixtures, they are typically clamped on the sides of the trim panel. This clamping inevitably obstructs the sides and top and bottom edges of the trim panel, preventing operation on these areas during trimming. Therefore, it is necessary to change the clamping position. Furthermore, when trimming the edges of the trim panel, it is necessary to change to another clamp to hold and fix the trim panel, which is quite cumbersome. Summary of the Invention

[0004] This invention provides a shaping device for automotive trim panel processing, which can solve the technical problem in the prior art that there is a shaping blind zone after the trim panel is clamped, which makes it impossible to shape the clamped part and requires changing the clamping position.

[0005] A shaping device for processing automotive trim panels includes a base plate, with limiting mechanisms installed on both sides of the base plate, and a dust suction mechanism connected to the rear of the two limiting mechanisms. A shaping robot for shaping automotive trim panels is connected to the middle of the front of the base plate. The vacuuming mechanism includes a rear concave plate, inside which a vacuum box is installed. Two fixing blocks are fixedly installed on the top of both the rear concave plate and the top of the vacuum box. An electric push rod is connected between the two fixing blocks on the front and rear coaxial lines. Two slide rails are installed at the bottom of the rear concave plate, and a slider that matches the slide rails is installed at the bottom of the vacuum box.

[0006] As a further technical solution of the present invention, the rear concave plate is U-shaped, and the dust suction port of the dust collection box faces the setting direction of the limiting mechanism.

[0007] As a further technical solution of the present invention, the limiting mechanism includes a support plate fixedly connected to the base plate, a lifting plate movably installed on the top of the support plate, a flip motor fixedly installed on one side of the vertical section of the lifting plate, and an electric push rod one fixedly connected to the drive shaft of the flip motor installed on the other side of the vertical section of the lifting plate. A clamping seat is fixedly connected to the end of the electric push rod one. A fixed plate is fixedly installed on the side of the support plate away from the lifting plate, and a transverse plate is movably installed on one side of the fixed plate. Two rows of parallel vacuum suction cups are fixedly installed on the top surface of the transverse plate. A horizontal plate is also fixedly installed on the side of the support plate away from the lifting plate. Two vertical plates are fixedly installed on one side of the horizontal plate. Positioning rods are fixedly connected between the two vertical plates and the side wall of the support plate. The horizontal plate is located below the fixed plate, and a sliding plate is slidably installed on the top of the horizontal plate. The sliding plate is slidably connected to the positioning rods, and an electric push rod two is connected between one side of the sliding plate and the side wall of the support plate. The electric push rod two is located between the two positioning rods. Two parallel connecting rods are fixedly connected between the transverse plate and the sliding plate.

[0008] As a further technical solution of the present invention, the transverse plate and the lifting plate are provided with a plurality of moving slots, and the fixed plate and the support plate are fixedly installed with guide rods that are slidably connected to the moving slots.

[0009] As a further technical solution of the present invention, a groove is provided on the top surface of the horizontal plate, and a movable block adapted to the groove is fixedly installed at the bottom of the sliding plate. The bottom of the horizontal plate is slidably connected to the groove through the movable block.

[0010] As a further technical solution of the present invention, a mounting plate is fixedly connected to the side of the support plate away from the horizontal plate, and a hydraulic cylinder is connected between the mounting plate and the horizontal section of the lifting plate.

[0011] As a further technical solution of the present invention, the telescopic end of the hydraulic cylinder is fixedly connected to the bottom surface of the transverse section of the lifting plate, and the hydraulic cylinder is located on one side of the tilting motor.

[0012] As a further technical solution of the present invention, a support inclined block is fixedly installed on the side of the support plate away from the horizontal plate, and the support inclined block is supported on the bottom of the mounting plate.

[0013] As a further technical solution of the present invention, the clamping seat includes a straight plate, and clamping plates with arc-shaped outer ends are movably installed on the upper and lower parts of the straight plate. An installation seat is provided inside the straight plate, and an intermediate plate is fixedly installed in the middle of the installation seat. Springs are fixedly connected to the upper and lower parts of the intermediate plate, and the ends of the springs are fixedly connected to the corresponding clamping plates through connecting plates.

[0014] As a further technical solution of the present invention, a mounting base is fixedly installed on one side of the straight plate, and the straight plate is fixedly connected to the electric push rod through the mounting base.

[0015] The beneficial effects of the present invention are as follows: The present invention sets up a limiting mechanism, and pushes the slide plate to slide by the electric push rod two. Under the drive of the slide plate, the connecting rod drives the transverse plate to move, thereby changing the horizontal position of the vacuum suction cup at the top, so that the vacuum suction cups on both sides can move to the bottom surface of the decorative panel for adsorption and fixation. When using this fixing method, not only will the upper end surface of the decorative panel be not blocked, but the outer perimeter of the decorative panel can also be exposed, which is convenient for the end surface of the decorative panel and for shaping processing. By setting up clamping seats in conjunction with electric push rod one, the extension of electric push rod one can drive two clamping seats to clamp on both sides of the trim panel respectively. When the clamping plates are subjected to force, they can drive the spring to extend. At this time, the restoring force of the spring can be used to make the two clamping plates clamp the trim panel tightly, which is convenient for clamping and fixing the trim panel when it needs to be flipped. With the lifting plate, the hydraulic cylinder can extend the lifting plate, so that the height of the trim panel can be increased after it is clamped by the clamping seat, which makes it easier to flip the panel over and turn the lower end face to the top for shaping. After the lifting plate moves down, it can drive the trim panel to be attracted and fixed by the vacuum suction cup, which makes it easy to remove the clamping seat. By incorporating a dust collection mechanism, the dust collection box can not only vacuum the trim panels during reshaping, but also adjust the position of the trim panels by pushing the electric push rod three times. When the trim panels are flipped, it can also effectively absorb the dust and impurities remaining on the end face of the trim panels. Attached Figure Description

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-7 As shown, a shaping device for processing automotive trim panels includes a base plate 1, with limiting mechanisms 2 installed on both sides of the base plate 1, and a dust suction mechanism 4 connected to the rear of the two limiting mechanisms 2. A shaping robot 3 for shaping automotive trim panels is connected to the middle of the front part of the base plate 1. The vacuuming mechanism 4 includes a rear concave plate 401, a vacuum box 402 is provided inside the rear concave plate 401, two fixing blocks 403 are fixedly installed on the top of both the rear concave plate 401 and the vacuum box 402, an electric push rod 405 is connected between the two fixing blocks 403 on the front and rear coaxial lines, and two slide rails 404 are installed on the bottom of the rear concave plate 401, and a slider adapted to the slide rails 404 is installed on the bottom of the vacuum box 402. The rear concave plate 401 is U-shaped, and the vacuum port of the vacuum box 402 faces the setting direction of the limiting mechanism 2.

[0021] Specifically, the electric actuator 405 extends and moves on the slide rail 404 in conjunction with the slider, which drives the dust collection box 402 to move, thus moving closer to the trim panel and absorbing the dust that falls off the trim panel when it is flipped.

[0022] The limiting mechanism 2 includes a support plate 201 fixedly connected to the base plate 1. A lifting plate 202 is movably mounted on the top of the support plate 201. A tilting motor 204 is fixedly mounted on one side of the vertical section of the lifting plate 202, and an electric push rod 205 fixedly connected to the drive shaft of the tilting motor 204 is mounted on the other side of the vertical section of the lifting plate 202. A clamping seat 206 is fixedly connected to the end of the electric push rod 205. A fixing plate 212 is fixedly mounted on the side of the support plate 201 away from the lifting plate 202, and a transverse plate 213 is movably mounted on one side of the fixing plate 212. Two rows of parallel vacuum suction cups 216 are fixedly mounted on the top surface of the transverse plate 213. A horizontal plate 207 is fixedly installed on the side away from the lifting plate 202. Two vertical plates 209 are fixedly installed on one side of the horizontal plate 207. Positioning rods 210 are fixedly connected between the two vertical plates 209 and the side wall of the support plate 201. The horizontal plate 207 is located below the fixed plate 212, and a sliding plate 208 is slidably installed on the top of the horizontal plate 207. The sliding plate 208 is slidably connected to the positioning rods 210. An electric push rod 211 is connected between one side of the sliding plate 208 and the side wall of the support plate 201. The electric push rod 211 is located between the two positioning rods 210. Two parallel connecting rods 214 are fixedly connected between the horizontal plate 213 and the sliding plate 208.

[0023] Specifically, the bottom of the trim panel is attracted and fixed by the vacuum suction cups 216 on both sides, which avoids obstruction when shaping the upper part. The lifting plate 202 can be raised and lowered. After the clamping seat 206 clamps the two sides of the trim panel, the lifting plate 202 rises to provide space for the trim panel to be flipped. The trim panel can then be flipped so that the other side of the trim panel is facing up, and the other side of the trim panel can be processed. Because the bottom surface of the trim panel is attracted and fixed, the edge of the trim panel is not obstructed, and the edge of the trim panel can also be shaped.

[0024] Both the transverse plate 213 and the lifting plate 202 are provided with several moving slots 217, and both the fixed plate 212 and the support plate 201 are fixedly installed with guide rods 218 that are slidably connected to the moving slots 217.

[0025] Specifically, when the transverse plate 213 and the lifting plate 202 move, the guide rod 218 extends from the corresponding moving slot 217, so that the transverse plate 213 and the lifting plate 202 have better stability when moving.

[0026] The top surface of the horizontal plate 207 is provided with a sliding groove, and the bottom of the sliding plate 208 is fixedly installed with a movable block that matches the sliding groove. The bottom of the horizontal plate 207 is slidably connected to the sliding groove through the movable block.

[0027] Specifically, by moving the block within the groove, the slide plate 208 moves more smoothly.

[0028] A mounting plate 215 is fixedly connected to the side of the support plate 201 away from the horizontal plate 207, and a hydraulic cylinder 203 is connected between the mounting plate 215 and the horizontal section of the lifting plate 202. The telescopic end of the hydraulic cylinder 203 is fixedly connected to the bottom surface of the horizontal section of the lifting plate 202, and the hydraulic cylinder 203 is located on one side of the tilting motor 204.

[0029] Specifically, the lifting plate 202 is raised by the hydraulic cylinder 203, thereby changing the height of the clamping seat 206.

[0030] A support wedge is fixedly installed on the side of the support plate 201 away from the horizontal plate 207, and the support wedge is supported on the bottom of the mounting plate 215.

[0031] The clamping base 206 includes a straight plate 2061. Clamping plates 2062 with curved outer ends are movably installed on both the upper and lower parts of the straight plate 2061. An installation base 2063 is provided inside the straight plate 2061. An intermediate plate 2064 is fixedly installed in the middle of the installation base 2063. Springs 2065 are fixedly connected to both the upper and lower parts of the intermediate plate 2064. The ends of the springs 2065 are fixedly connected to the corresponding clamping plates 2062 through connecting plates. An installation base 2063 is fixedly installed on one side of the straight plate 2061. The straight plate 2061 is fixedly connected to the electric push rod 205 through the installation base 2063.

[0032] Specifically, the upper and lower clamping plates 2062 clamp the trim panel. For trim panels of different thicknesses, the restoring force of the extended spring 2065 can clamp the trim panel tightly.

[0033] This invention discloses a shaping device for processing automotive trim panels. In use, the trim panel is first fixed by two limiting mechanisms 2. The distance between the vacuum suction cups 216 on both sides is adjusted according to the length of the trim panel. The sliding plate 208 is pushed by the electric push rod 211. Under the drive of the sliding plate 208, the connecting rod 214 drives the transverse plate 213 to move, thereby changing the horizontal position of the vacuum suction cup 216 on the top, and then changing the vacuum suction cups 216 on both sides. The trim panel is placed on the vacuum suction cups 216 on both sides, and the bottom surface of the trim panel is adsorbed.

[0034] After the trim panel is fixed by adsorption, its upper surface and edges are exposed, which will not cause obstruction. The trim panel can be trimmed by the trimming robot 3. For example, the trimming robot 3 can be connected to a polishing device for polishing and trimming. The top surface and edges of the trim panel can be trimmed first.

[0035] When the trim panel is attached to the vacuum suction cup 216, its two sides face the two clamping seats 206. After the upper surface is shaped, the two clamping seats 206 can be clamped on both sides of the trim panel by extending the electric push rod 205. When the clamping plate 2062 is under force, it can drive the spring 2065 to extend. At this time, the restoring force of the spring 2065 can be used to clamp the trim panel tightly with the two clamping plates 2062.

[0036] Release the vacuum suction cup 216. At this time, the hydraulic cylinder 203 drives the lifting plate 202 to rise, so that the vacuum suction cup 216 is separated from the trim panel, providing space for the trim panel to flip. The flipping motor 204 drives the electric push rod 205 to flip, causing the trim panel to flip so that its lower end face is facing up. Then, the lifting plate 202 is lowered so that the trim panel is attached to the vacuum suction cup 216 and is attracted by the vacuum suction cup 216. At this time, the electric push rod 205 is retracted to drive the clamping seat 206 to be pulled away from the sides of the trim panel, so that the lower end face of the trim panel can be shaped.

[0037] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
