Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a cutting device for automotive lamp cover gates. Background Technology

[0002] Automotive headlight covers are core precision exterior components of automotive lighting systems. In the injection molding process, the mold needs to reserve a gate and runner structure. After the headlight cover is demolded, columnar or sheet-like sprue waste will remain at the gate position. It is necessary to go through a gate cutting process to remove the residual sprue waste to meet the product appearance and assembly standards.

[0003] Patent CN117020441B discloses a cutting device for automotive lamp cover gates, including an intermittent feeding mechanism, a reciprocating grinding and cutting mechanism, and a clamping mechanism that cooperate with each other. The reciprocating grinding and cutting mechanism includes a mounting frame that can reciprocate along the X-axis, and a mounting seat that can reciprocate along the Y-axis is slidably mounted on the mounting frame. A cutter and a grinder are mounted on the bottom of the mounting seat. The cutter includes a hydraulic lifting rod and a laser cutting head connected sequentially from top to bottom. The grinder includes a fixed sleeve and a movable sleeve that can reciprocate and lift relative to the fixed sleeve along the Z-axis, and a grinding ball that can rotate around the Z-axis is embedded at the bottom of the movable sleeve. The above invention can complete the cutting and grinding of the lamp cover gate in one step without secondary positioning, effectively ensuring the processing accuracy of the lamp cover surface.

[0004] When laser cutting lampshades, fine plastic slag and large pieces of gate waste are generated, which fall freely and scatter on the workbench or equipment gaps, requiring manual cleaning at regular intervals. However, during the cleaning cycle, the accumulation of waste blocks the cutting light path, causing the laser focus to shift, cutting burrs, and reducing the cutting effect. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by proposing an automotive lamp cover gate cutting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cutting device for automotive lamp cover gates includes: a processing cabinet and a laser cutting device installed on the inner wall of the processing cabinet. The processing cabinet is equipped with a base frame, and multiple placement blocks are equidistantly arranged on the base frame, forming an arc-shaped placement frame with the center facing upward. The placement block has an installation opening in the middle, and an adsorption component is provided inside the installation opening. The adsorption component is used to adsorb the lampshade from below. The bottom of the processing cabinet is provided with a material guide trough, which is located below the base frame, and two scrapers are symmetrically arranged on both sides of the material guide trough. An adjustment component is provided below the base frame. The adjustment component includes a bottom tube, a connecting rod, a piston block, and a telescopic rod. The bottom tube is fixedly connected to the bottom frame. The piston block is slidably disposed inside the bottom tube. The connecting rod is fixedly connected between the piston block and the adsorption component. The telescopic rod is fixedly installed at the lower end of the bottom tube, and the upper end of the telescopic rod is fixedly connected to the piston block to drive the piston block to slide up and down. Two telescopic components are symmetrically arranged on both sides of the bottom tube, and the two telescopic components are used to drive the scraper to move.

[0007] Preferably, the adsorption assembly includes an installation tube, a suction cup end, and a suction piston. The installation tube is fixedly installed inside the installation port, the suction cup end is fixedly connected to the upper end of the installation tube, and the suction piston is sealed and slidably disposed inside the installation tube, with its bottom fixedly connected to the upper end of the connecting rod.

[0008] Preferably, the telescopic assembly includes a connecting pipe and a sliding rod. The connecting pipe is fixedly connected to the bottom side of the bottom pipe and located below the piston block. One end of the sliding rod is sealed and slidably disposed inside the connecting pipe, and the other end is vertically and fixedly connected to the inner wall of the scraper.

[0009] Preferably, the base frame includes four support blocks and a base plate. The four support blocks are fixedly connected inside the processing cabinet and located at the four corners of the guide chute. The four corners of the base plate are fixedly connected to the upper ends of the four support blocks respectively. The base plate has a trapezoidal cross section, and the inclined two sides are used for waste material guidance.

[0010] Preferably, a limiting port is provided on the side of the guide trough, and multiple scraper blocks are provided below the scraper, with the scraper blocks being slidably positioned inside the limiting port.

[0011] Preferably, multiple clamping components are symmetrically arranged on both sides of the bottom surface of the base frame, and the clamping components are used to clamp the lampshade from the side.

[0012] Preferably, the clamping assembly includes a rotating base and a clamping bar. The rotating base is fixedly connected to the bottom of the base frame, and the clamping bar is rotatably connected to the rotating base. The clamping bar is an arc-shaped bar, with one end near the control component bent downward and the other end away from the control component bent upward. The upward-bent end of the clamping bar is made of an elastic material.

[0013] Preferably, a partition is fixedly connected inside the bottom tube, which divides the bottom tube into a lower hydraulic chamber and an upper sliding space. The piston block is slidably disposed inside the hydraulic chamber, and two strip-shaped openings are symmetrically opened on both sides of the sliding space.

[0014] Preferably, the sliding space is provided with a squeezing component, which is used to squeeze the deflecting clamping bar.

[0015] Preferably, the extrusion assembly includes a connecting ring and two pressure strips. The connecting ring is fixedly connected to the connecting rod and located inside the sliding space. The two pressure strips are fixedly connected to both sides of the connecting ring and located on the upper side of the ends of adjacent clamping strips.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention relies on the synchronous linkage of the control component with the adsorption component and multiple sets of elastic clamping components to form a three-dimensional composite positioning with curved surface multi-point support, bottom negative pressure adsorption, and double-sided elastic clamping. The arc-shaped placement frame matches the curved surface of the lampshade perfectly, dispersing the force and avoiding warping deformation of the thin-walled lampshade. The silicone suction cup and polyurethane elastic clamping ends are free of hard scratches and indentations, reducing the scrap rate of transparent lampshade appearance. The entire positioning mechanism moves synchronously without time difference, greatly improving the consistency of laser-cut gate size, significantly reducing gate burrs, and reducing the workload of subsequent grinding processes. 2. The hydraulic circuit of the control component synchronously drives the scrapers on both sides. Each time a workpiece is unloaded, the cutting waste generated is automatically and synchronously swept away. The trapezoidal bottom plate guide slope and the guide chute realize complete collection of waste, and there is no waste accumulation that obstructs the laser beam path. Moreover, there is no need to stop the machine for manual cleaning. Waste is centrally recycled, and plastic raw materials can be repeatedly granulated, reducing raw material loss costs. 3. Relying solely on a single telescopic rod as the power source for all actuators, the mechanical linkage links the positioning mechanism and the hydraulic circuit links the cleaning mechanism to achieve synchronized sequential actions of adsorption, clamping, and cleaning; the number of air circuits, solenoid valves, and sensors is reduced, significantly reducing pipeline leaks and electrical timing failure points, and equipment maintenance time is significantly reduced; the energy consumption of a single power source is lower compared to multi-drive equipment, resulting in lower long-term production and operation costs; 4. The entire linkage mechanism relies on mechanical rigid linkages and closed hydraulic circuits for synchronization. The timing of the actions is completely constrained by the mechanical structure and does not depend on the electronic control delay program. Fluctuations in air source pressure and power supply voltage will not cause misalignment of clamping, adsorption, and cleaning actions, eliminating workpiece slippage caused by timing deviations. It is also compatible with various specifications of automotive front and rear lamp covers without the need to change tooling grippers, and is suitable for flexible production of multiple types of lamp covers. 5. All cutting waste is collected in the bottom guide trough, preventing fine molten slag from scattering inside the processing cabinet and avoiding the fire hazard caused by the accumulation of high-temperature plastic molten slag; the inside of the processing cabinet is clean and free of waste dust, improving the workshop working environment; it reduces the frequency of manual entry into the processing cabinet to clean up waste and lowers the safety risk of close contact between manuals and the laser cutting head.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0021] Reference Figures 1-9 A cutting device for automotive lamp cover gates includes: a processing cabinet 1 and a laser cutting device 2 installed on the inner wall of the processing cabinet 1. The processing cabinet 1 is provided with a base frame 3, and multiple placement blocks 4 are equidistantly arranged on the base frame 3, forming an arc-shaped placement frame with the center upward. The placement block 4 has an installation opening in the middle, and an adsorption component 5 is provided inside the installation opening. The adsorption component 5 is used to adsorb the lamp cover from below. The bottom of the processing cabinet 1 is provided with a guide trough 13, which is located below the base frame 3, and two scrapers 10 are symmetrically arranged on both sides of the guide trough 13. A control assembly 6 is provided below the base frame 3. The control assembly 6 includes a bottom tube 61, a connecting rod 62, a piston block 63, and a telescopic rod 64. The bottom tube 61 is fixedly connected to the bottom of the base frame 3. The piston block 63 is slidably disposed inside the bottom tube 61. The connecting rod 62 is fixedly connected between the piston block 63 and the adsorption assembly 5. The telescopic rod 64 is fixedly installed at the lower end of the bottom tube 61, and the upper end of the telescopic rod 64 is fixedly connected to the piston block 63 to drive the piston block 63 to slide up and down. Two telescopic components 7 are symmetrically arranged on both sides of the bottom tube 61, and the two telescopic components 7 are used to drive the scraper 10 to move.

[0022] In embodiments applying the above technical solutions, the prior art uses a flat worktable to place the lampshade. Since the automotive lampshade is a bi-directional curved surface, the flat support can only contact certain points of the lampshade, leaving the workpiece suspended. Vibrations from the laser cutting equipment can cause slight displacement of the lampshade. This invention uses equidistant placement blocks 4 spliced ​​into an arc-shaped placement frame, where the curved surface perfectly matches the lampshade's contour. Multi-point support distributes the force, and the adsorption component 5 is integrated inside the placement block 4, synchronously driven by the connecting rod 62 of the control component 6, eliminating the need for an independent negative pressure power source. The arc-shaped placement frame, spliced ​​from multiple placement blocks 4, fits perfectly against the outer curved surface of the lampshade, providing even support at multiple points. This disperses the weight of the lampshade itself and the instantaneous thermal stress from laser cutting, preventing localized warping of the lampshade caused by single-point support. At the same time, the adsorption component 5 forms a stable negative pressure, completely fixing the thin-walled lampshade. The negative pressure generated by mechanical changes simplifies the structure and reduces potential failure points. The downward movement of the control component 6 and the telescopic rod 64 synchronously drives the negative pressure generation of the adsorption component 5 and the clamping component 8 to clamp. The two positioning mechanisms have no time difference in action, and the bottom adsorption and lateral clamping are completed synchronously, forming a three-dimensional limit constraint in the upper, lower, left, and right directions. When the control component 6 moves upward, the adsorption is depressurized synchronously and the clamping opens synchronously, which will not cause the workpiece to tilt, fall, or collide due to the release of one side mechanism first, thus reducing the workpiece scrap rate. The entire positioning mechanism relies on only the telescopic rod 64 as a single power source, eliminating the need for two independent drive cylinders for clamping and adsorption, resulting in a simple structure, high sensitivity, and reduced probability of damage.

[0023] The preferred technical solution in this embodiment is: Reference Figures 3-7The adsorption assembly 5 includes an installation tube 51, a suction cup end 52, and a suction piston 53. The installation tube 51 is fixedly installed inside the installation port, the suction cup end 52 is fixedly connected to the upper end of the installation tube 51, and the suction piston 53 is sealed and slidably disposed inside the installation tube 51, and its bottom is fixedly connected to the upper end of the connecting rod 62. The silicone suction cup end 52 makes soft contact with the bottom surface of the lampshade, without any hard contact scratches, and is suitable for the high surface requirements of transparent lampshade exterior parts. When fixing, the suction piston 53 moves down with the connecting rod 62, quickly forming a stable negative pressure inside the mounting tube 51, and completely flexibly fixing the inner wall of the thin-walled lampshade. The distributed adsorption components 5 can stably and effectively form multi-point adsorption and fixation on the placed lampshade. While ensuring the fixation effect, it avoids the lampshade from shifting position during the cutting process, reduces the generation of cutting burrs, and ensures the cutting effect.

[0024] Reference Figure 4 , Figure 5 and Figure 7 The telescopic component 7 includes a connecting pipe 71 and a sliding rod 72. The connecting pipe 71 is fixedly connected to the bottom side of the bottom pipe 61 and located below the piston block 63. One end of the sliding rod 72 is sealed and slidably disposed inside the connecting pipe 71, and the other end is vertically fixedly connected to the inner wall of the scraper 10. The base frame 3 includes four support blocks 31 and a base plate 32. The four support blocks 31 are fixedly connected inside the processing cabinet 1 and located at the four corners of the guide trough 13. The four corners of the base plate 32 are fixedly connected to the upper ends of the four support blocks 31 respectively. The base plate 32 has a trapezoidal cross section, and the inclined two sides are used for waste material guidance. The guide trough 13 has a limiting port on its side, and a plurality of scraper blocks 11 are provided below the scraper 10. The scraper blocks 11 are slidably positioned inside the limiting port.

[0025] Traditional cutting equipment lacks an automatic cleaning structure, causing plastic slag and large pieces of waste material from laser cutting to fall and accumulate on the worktable. This waste accumulation obstructs the laser cutting beam, causing the laser focus to shift and resulting in burrs on the cut surface. Furthermore, manual cleaning of the waste material requires machine shutdown, and the scattered waste material falls into the gaps of the equipment, making it difficult to clean. The trapezoidal base plate 32 has inclined guide slopes on both sides, and the cutting waste automatically slides down to the bottom guide trough 13 by its own weight, reducing the debris from being stuck on the surface of the base frame 3. The scraper 10 has multiple scraper blocks 11 at the bottom that are completely in contact with the bottom surface of the guide trough 13 and slide along the limiting port. The telescopic component 7 is driven by hydraulic oil. During the placement and fixing process, the control component 6 drives the telescopic component 7 to push outward, thereby moving the two scrapers 10 to the outside and forming a barrier on both sides of the base frame 3 to prevent the cut waste from falling to the outside and being unable to be cleaned. After the cutting is completed, the piston block 63 of the control component 6 moves upward, and the hydraulic oil moves inward, thereby driving the two scrapers 10 to move from the sides to the center. The two scrapers 10 push the waste that has fallen inside the barrier to the guide trough 13. The scraper 10 has a stable thrust and can push large pieces of gate waste and micron-sized molten slag mixtures, and the cleaning is smooth without jamming. The cleaning process is completely parallel to the workpiece unloading process and does not occupy extra processing time. Each time the workpiece is unloaded, the waste cleaning is automatically completed. There is no waste accumulation on the worktable throughout the cutting process, the laser beam path is always unobstructed, the quality of the cutting section is stable, and the defect rate is reduced. All waste is collected in the guide trough 13. A waste collection box can be attached to the end of the guide trough 13 to centrally recycle plastic waste, which is convenient for recycling and granulation. The telescopic component 7 of this invention is synchronously driven by the hydraulic cavity of the control component 6, without the need for a separate power source. The scraper 10 cleans synchronously with the workpiece clamping. The trapezoidal base plate 32 guides the inclined surface and cooperates with the guide trough 13 to collect waste materials, thus solving the defects of waste accumulation, manual shutdown for cleaning, and additional drive required for the cleaning mechanism.

[0026] Reference Figure 6 , Figure 8 and Figure 9 The base frame 3 has multiple clamping components 8 symmetrically arranged on both sides of its bottom surface. The clamping components 8 are used to clamp the lampshade from the side. The clamping assembly 8 includes a rotating base 81 and a clamping bar 82. The rotating base 81 is fixedly connected to the bottom of the base frame 3, and the clamping bar 82 is rotatably connected to the rotating base 81. The clamping bar 82 is an arc-shaped bar, with one end near the control assembly 6 bent downward and the other end away from the control assembly 6 bent upward. The upward-curved end of the clamping bar 82 is made of an elastic material.

[0027] Traditional lampshade cutting and clamping mechanisms mostly use rigid linear jaws. The jaw contact surface is made of hard metal, which easily causes indentations when clamping transparent lampshades, directly causing the lampshade to be scrapped. In addition, the jaws move linearly and cannot adapt to the curved surface of curved lampshades. They can only contact a small area on the edge of the lampshade, resulting in insufficient clamping stability. The curved clamping strip 82 is bent along the curvature of the lampshade surface, and the clamping end is made of polyurethane elastic material. Multiple clamping strips 82 can fit in large areas with the curved surface of the lampshade, avoiding defects such as indentation and stress whitening on the light-transmitting surface of the lampshade. The clamping bar 82 rotates around the rotating seat 81 to clamp the lamp cover, which can be adapted to different specifications of front and rear lamp covers without changing the clamping tooling; multiple clamping components 8 are evenly arranged along the arc-shaped placement frame, with multiple lateral constraints and bottom adsorption, so that the lamp cover is fully limited in multiple degrees of freedom. There is no slight shaking during high-speed laser cutting, and the cut surface of the gate is flat, saving the manual grinding station.

[0028] Reference Figure 7 , Figure 8 and Figure 9 The bottom tube 61 is fixedly connected to a partition 12, which divides the bottom tube 61 into a lower hydraulic chamber and an upper sliding space. The piston block 63 is sealed and slidably disposed inside the hydraulic chamber. Two strip-shaped openings are symmetrically opened on both sides of the sliding space. The connecting rod 62 is sealed and slidably disposed in the middle of the partition. A sealing ring is provided inside the sliding space. The sealing ring is sleeved with the connecting rod 62 to enhance the sealing effect on the hydraulic chamber when the connecting rod moves. The sliding space is provided with a pressing component 9, which is used to press the deflection clamping bar 82. The extrusion assembly 9 includes a connecting ring 91 and two pressure strips 92. The connecting ring 91 is fixedly connected to the connecting rod 62 and is located inside the sliding space. The two pressure strips 92 are fixedly connected to both sides of the connecting ring 91 and are located on the upper side of the ends of the adjacent clamping strips 82. When the control component 6 moves downward, the pressing strip 92 of the extrusion component 9 presses down the clamping strip 82, and the connecting rod 62 pulls down the suction piston 53 simultaneously. The lateral clamping force and the bottom suction pull act on the lamp cover at the same time, dispersing the single-point stress. There is no residual extrusion stress inside the lamp cover, and the lamp cover does not rebound deformation after cutting. The pressing strip 92 of the extrusion component 9 moves up and down synchronously with the connecting rod 62. The mechanical rigid linkage has no electrical control delay. The telescopic rod 64 clamps and locks synchronously the moment it extends, and there is no clamping lag. When the control component 6 moves upward, the pressing strip 92 lifts up synchronously. The clamping strip 82 automatically opens elastically by relying on the torsion spring inside the rotating seat 81. At the same time, the suction negative pressure is released synchronously. There is no suction pulling or clamping jamming when picking up the part. The entire clamping drive is realized synchronously by the hydraulic and mechanical linkage of the control component 6. The internal partition 12 of the bottom tube 61 separates the hydraulic chamber from the sliding space, and the hydraulic oil and the mechanical linkage movement area are isolated from each other. The hydraulic oil will not contaminate the lamp cover workpiece, and no additional protective baffle is required. The hydraulic chamber and the connecting pipes 71 on both sides form a closed synchronous hydraulic circuit. The downward displacement of the piston block 63 corresponds linearly to the sliding distance of the scraper 10, and the displacement synchronization error is small.

[0029] The existing equipment has three sets of mechanisms for adsorption, clamping, and waste cleaning, each equipped with an independent power cylinder or hydraulic rod. Each actuator is equipped with an independent solenoid valve, displacement sensor, and time delay control module, resulting in a complex oil and air pipeline system and numerous leakage and failure points.

[0030] The single telescopic rod 64 in the control component 6 serves as the power input component for the entire mechanism. Only one set of solenoid valves is configured to control the extension and retraction of the telescopic rod 64, reducing the number of air lines and lowering the failure rate of line leakage. The cleaning stroke of the scrapers 10 on both sides is symmetrical, with no cleaning residue on one side. At the same time, the mechanical linkage transmission has no electrical delay, and the displacement of the telescopic rod 64 is directly and synchronously transmitted to the adsorption and clamping mechanism. The synchronization of the action is not affected by voltage or air source pressure fluctuations, which greatly improves the stability of equipment operation and reduces long-term production energy consumption costs.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
