Description

Technical Field

[0001] This utility model relates to the field of plastic molding and joining technology, and in particular to a glue application device for quick switching of automotive end caps. Background Technology

[0002] Automotive parts gluing production lines typically rely on specialized molds to position and glu the workpieces. A single production line needs to be compatible with the simultaneous production of multiple workpieces. The requirements for production line changes and multi-category co-production necessitate that the molds, while maintaining a uniform external size, possess the basic conditions for multi-product compatibility and rapid workstation switching.

[0003] Currently, glue application production lines adapting to the production of multiple workpieces mainly adopt two mold solutions. The first is a one-workpiece-one-mold system, where different workpieces are equipped with their own dedicated molds. With this system, switching products requires replacing the entire mold set, and operators must complete multiple processes such as mold hoisting, alignment, locking, and debugging, resulting in lengthy mold changes. Simultaneously purchasing and storing multiple molds significantly increases mold manufacturing costs and warehousing management pressure. Large-volume mold transfer and storage can lead to problems such as mold damage and inconsistent numbering, resulting in low overall production efficiency under frequent changeovers. The second solution involves widening and enlarging the mold base plate, arranging multiple workpieces for contour positioning within the same mold plane. While this reduces the number of molds, accommodating multiple contour structures necessitates enlarging the overall mold dimensions. Mold specifications cannot be standardized across production lines, and the weight and floor space of larger molds increase simultaneously. Equipment versatility is poor, and the difficulty of mold processing, transportation, and installation is significantly increased, making it difficult to adapt to standardized, compact production line layouts.

[0004] Therefore, this utility model proposes a glue application device for quick switching of automotive end cap stations to address the shortcomings of existing technologies. Utility Model Content

[0005] In existing technologies, the co-line gluing of multiple types of workpieces either requires multiple sets of molds, resulting in long mold changeover times and high mold management costs, or enlarges the mold base plate, leading to inconsistent mold dimensions and poor versatility. Neither of these solutions can achieve rapid product station switching within standard-sized molds, thus restricting the flexible production efficiency of the production line.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a glue application device for quick switching of automotive end caps, comprising a base plate, a fixed mold station component mounted on the top surface of the base plate, a moving mold lifting component mounted below the base plate, and an electronic control operation component mounted on the outside of the base plate.

[0007] The fixed mold station assembly includes a fixed mold base plate and a fixed mold molding block. The fixed mold base plate is fixedly assembled on the upper surface of the base plate, and the fixed mold molding block is fastened to the upper surface of the fixed mold base plate.

[0008] The moving mold lifting assembly includes a lifting cylinder, a connecting plate, a moving mold base plate, and a moving mold modeling block. The base plate has through holes for the moving mold modeling block to pass through and avoid obstacles. The lifting cylinder is vertically fixed to the bottom of the base plate. The end of the piston rod of the lifting cylinder is rigidly connected to the connecting plate. The upper surface of the connecting plate is fastened to the bottom surface of the moving mold base plate. The moving mold modeling block is fixed on the moving mold base plate.

[0009] The electronic control components include a moving and fixed mold switching button, a vacuum gauge, and a product sensing switch. The moving and fixed mold switching button is installed on the outside of the substrate and is connected to the lifting cylinder via electronic control. The vacuum gauge is mounted on the side of the substrate.

[0010] The fixed and moving imitation blocks are staggered, with the cross-sectional dimension of the moving imitation block being smaller than the inner diameter of the hole, and the outer wall of the moving imitation block not contacting the outer wall of the fixed imitation block.

[0011] Preferably, both the fixed mold base plate and the moving mold base plate are equipped with vacuum suction cups, and the output ends of the two vacuum suction cups are connected to negative pressure pipelines, one end of which is connected to a vacuum gauge.

[0012] Preferably, the product induction switches are divided into two groups and respectively disposed on the outside of the fixed imitation block and the moving imitation block, and the product induction switches are electrically connected to the control circuit of the corresponding vacuum suction cup.

[0013] Preferably, when the moving imitation block moves to the bottom limit position following the lifting cylinder, the top surface height of the moving imitation block is lower than the top surface height of the fixed imitation block.

[0014] Preferably, when the moving imitation block moves upward to the top limit position following the lifting cylinder, the top surface height of the moving imitation block is higher than the top surface height of the fixed imitation block.

[0015] Preferably, the moving and fixed mold switching button is a manually operated force point that outputs an electrical signal to control the extension and retraction of the lifting cylinder; the vacuum gauge is connected to the independent vacuum suction cup negative pressure pipeline inside the fixed and moving mold blocks respectively.

[0016] Preferably, the moving mold base plate rises and falls synchronously with the lifting cylinder, and the moving mold shaping block adapts to the second workpiece contour.

[0017] The glue application device for quick switching stations of automotive end caps provided in this embodiment of the utility model has at least one of the following technical effects:

[0018] 1. In this utility model, the lifting cylinder drives the moving mold lifting component, which, together with the alternating high and low layered structure of the moving and static imitation blocks, allows for one-click switching between two workpiece stations by simply pressing the switching button. This eliminates the need to disassemble and replace the entire set of molds, significantly reducing the product changeover time on the production line.

[0019] 2. In this utility model, a dual-station positioning structure is integrated on a substrate of uniform size, eliminating the need to widen or enlarge the mold base plate. One mold can replace two independent molds, reducing mold manufacturing and warehousing management costs and achieving mold specification standardization. Attached Figure Description

[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0028] Example:

[0029] Please refer to Figs. 1 to 4This utility model provides a glue application device for quick switching of automotive end caps, which solves the problems in the prior art where glue application for multiple types of workpieces on a single production line either involves multiple sets of molds, resulting in high costs and long mold changing times, or widening the molds, leading to inconsistent specifications and poor versatility.

[0030] A glue application device for quick-switching stations of automotive end caps includes a base plate 8, a fixed mold station assembly, and a moving mold lifting assembly. The fixed mold station assembly is installed on the top surface of the base plate 8, and the moving mold lifting assembly is assembled below the base plate 8. An electronic control operation assembly is provided on the outside of the base plate 8. The base plate 8 provides a load-bearing reference for the entire machine and also provides covering and installation space for the internal lifting and positioning structures. The fixed mold station assembly is used to fix the first type of workpiece and complete the positioning and glue application. The moving mold lifting assembly is used to drive the moving mold base plate 2 to lift and lower as a whole, realizing the switching between the two stations. The electronic control operation assembly is used to manually control the lifting action, monitor the vacuum adsorption status in real time, and identify the presence or absence of the workpiece.

[0031] The fixed mold station assembly includes a fixed mold base plate 1 and a fixed mold forming block 4. The fixed mold base plate 1 is fixedly mounted on the upper end face of the base plate 8, and the fixed mold forming block 4 is fastened to the upper surface of the fixed mold base plate 1. The fixed mold base plate 1 provides a mounting carrier for the fixed mold forming block 4, the corresponding vacuum suction cup and the product induction switch 7. The fixed mold forming block 4 is processed according to the shape of the first workpiece to limit the planar and vertical displacement of the workpiece and achieve precise positioning.

[0032] The moving mold lifting assembly includes a lifting cylinder 9, a connecting plate 10, a moving mold base plate 2, and a moving imitation block 3. The base plate 8 has a through hole 11 for the moving imitation block 3 to pass through and avoid obstacles. The lifting cylinder 9 is vertically fixed to the bottom of the base plate 8. The piston rod end of the lifting cylinder 9 is rigidly connected to the connecting plate 10. The upper surface of the connecting plate 10 is tightly connected to the bottom surface of the moving mold base plate 2. The moving mold base plate 2 rises and falls synchronously with the lifting cylinder 9. The moving imitation block 3 is fixed on the moving mold base plate 2 and adapts to the second workpiece contour. The lifting cylinder 9 outputs linear extension and retraction power, which drives the entire moving mold base plate 2 to move vertically through the connecting plate 10. The connecting plate 10 acts as a force transmission transition component to ensure that multiple sets of lifting cylinders 9 rise and fall synchronously. The through hole 11 provides clearance space for the moving imitation block 3 to move up and down, avoiding interference with the base plate 8 during the lifting process.

[0033] The fixed imitation block 4 and the moving imitation block 3 are arranged in an odd-even staggered pattern on the top view plane of the substrate 8, and their horizontal projections do not overlap, thus eliminating horizontal structural interference. The height of the moving imitation block 3 relative to the fixed imitation block 4 is changed by the moving mold lifting component, so that the two work positions can be alternately exposed.

[0034] The electronic control components include a moving / fixed mold switching button 5, a vacuum gauge 6, and a product sensor switch 7. The moving / fixed mold switching button 5 is installed on the outside of the base plate 8 and is electrically connected to the lifting cylinder 9. The moving / fixed mold switching button 5 is a manual operation force point, and outputs an electrical signal to control the extension and retraction of the lifting cylinder 9. The vacuum gauge 6 is mounted on the side of the base plate 8 and is connected to the independent vacuum suction cup negative pressure pipelines inside the fixed imitation block 4 and the moving imitation block 3, respectively, to display the vacuum degree inside the pipeline in real time, so that the operator can judge whether the workpiece is firmly adsorbed. The product sensor switch 7 is respectively arranged on the side of the fixed imitation block 4 and the moving imitation block 3. The product sensor switch 7 is electrically connected to the corresponding vacuum suction cup control circuit. When the workpiece is detected to be in place, the vacuum adsorption is automatically started. When there is no workpiece, the vacuum circuit is cut off to save air source.

[0035] When the lifting cylinder 9 is fully retracted to its low position, the moving mold base plate 2 drives the moving imitation block 3 to descend. The overall height of the moving imitation block 3 is lower than that of the fixed imitation block 4. The moving imitation block 3 is stored and hidden under the fixed mold base plate 1, with only the fixed imitation block 4 exposed. The first type of workpiece can be placed for gluing. After pressing the moving and fixed mold switching button 5, the piston rod of the lifting cylinder 9 extends upward, pushing the connecting plate 10 and the moving mold base plate 2 to rise as a whole. The moving imitation block 3 rises synchronously to a height exceeding that of the fixed imitation block 4. The fixed imitation block 4 is hidden at a low position, with only the moving imitation block 3 exposed. The second type of workpiece can be placed to complete the gluing process. Pressing the switching button repeatedly can cycle between the two product stations.

[0036] As a preferred technical solution, the connecting plate 10 is integrally formed from a single piece of steel plate. Multiple sets of threaded mounting holes are opened on the connecting plate 10, which are locked and fixed to the piston rod of the lifting cylinder 9 and the moving mold base plate 2 respectively, ensuring that the lifting force is uniform and there is no off-center load.

[0037] As a preferred technical solution, multiple vacuum adsorption channels are pre-embedded inside both the fixed imitation block 4 and the moving imitation block 3. Adsorption holes are opened at the ends of the channels. The two channels are independent of each other and are equipped with independent solenoid valves, which can control the adsorption and depressurization of the corresponding workstations separately.

[0038] As a preferred technical solution, the product's induction switch 7 adopts a diffuse reflection photoelectric switch with an adjustable bracket installation, which can finely adjust the sensing height according to the thickness of the workpiece, adapting to automotive parts of different thicknesses.

[0039] As a preferred technical solution, the lifting cylinder 9 is an adjustable stroke cylinder with a magnetic ring. Buffer structures are set at both ends of the cylinder to reduce the impact and vibration when the moving mold base plate 2 is raised and lowered to the correct position, thus preventing the workpiece from shifting.

[0040] As a preferred technical solution, the substrate 8 is formed by welding aluminum alloy profiles. The surface of the substrate 8 is treated with hard anodizing for wear resistance. Wear-resistant copper sleeves are embedded in the inner wall of the hole 11 to reduce the frictional wear of the moving imitation block 3 sliding up and down.

[0041] As a preferred technical solution, the moving and stationary mold switching button 5 adopts a self-resetting button with indicator lights. The two states of cylinder rising and falling correspond to different light colors, which intuitively reflect the currently activated workstation. The vacuum gauge 6 is equipped with pressure alarm contacts. When the negative pressure is insufficient, it will automatically sound and light an alarm to prevent the workpiece from falling off during the glue application process.

[0042] Working principle: When the user presses the moving mold switching button 5 on the base plate 8, the moving mold switching button 5 outputs a lifting control signal to the lifting cylinder 9. The piston rod of the lifting cylinder 9 extends and retracts synchronously, driving the moving mold base plate 2 connected to the connecting plate 10 to rise and fall as a whole in the vertical direction. The moving imitation block 3 fixed on the moving mold base plate 2 moves synchronously with the moving mold base plate 2. The fixed mold base plate 1 is fixedly installed above the base plate 8. The position of the fixed imitation block 4 on the fixed mold base plate 1 remains unchanged. The moving imitation block 3 and the fixed imitation block 4 are arranged horizontally and staggered. Corresponding avoidance through holes 11 are opened on the base plate 8 to allow the moving imitation block 3 to pass up and down, avoiding spatial interference during the lifting process.

[0043] When the lifting cylinder 9 is fully retracted and the moving mold base plate 2 is lowered to the low position, the overall height of the moving imitation block 3 is lower than that of the fixed imitation block 4. The moving imitation block 3 is completely stored under the fixed mold base plate 1, with only the fixed imitation block 4 exposed. The first type of workpiece is placed on the fixed imitation block 4. After the product induction switch 7 detects that the workpiece is in place, the corresponding vacuum circuit is activated. The vacuum gauge 6 monitors the negative pressure of the pipeline in real time. The vacuum suction cup adsorbs the workpiece to complete the positioning. The equipment performs the glue application operation. After the processing is completed, the vacuum is cut off and the workpiece can be removed.

[0044] The user presses the moving and fixed mold switching button 5 again, and the piston rod of the lifting cylinder 9 extends upward, pushing the moving mold base plate 2 to a high position. The moving imitation block 3 then moves upward to a height exceeding that of the fixed imitation block 4. The fixed imitation block 4 is hidden by the low position, and only the moving imitation block 3 is exposed. The second type of workpiece is placed on the moving imitation block 3. After the product induction switch 7 recognizes the workpiece, the corresponding vacuum adsorption is activated. The vacuum suction cup locks the workpiece to complete the glue application process. After the process is completed, the vacuum is released and the workpiece is removed.

[0045] When it is necessary to switch production products again, press the moving and fixed mold switching button 5 repeatedly to control the lifting cylinder 9 to retract and lower the moving mold base plate 2. The moving imitation block 3 will fall back and hide, and the fixed imitation block 4 will re-expose. This will switch back to the first workpiece gluing condition. This cycle can be repeated to achieve one-click switching of gluing between the two workpiece stations.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
