Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, specifically to a headlight cooling fan installation device. Background Technology

[0002] Vehicle headlights generate a significant amount of heat during operation. If this heat is not dissipated in time, the temperature of the LED chips will continue to rise, accelerating light decay, causing color temperature drift, and in severe cases, burning out the chips, shortening the headlight's lifespan, affecting illumination performance, and threatening driving safety. Therefore, installing a cooling fan inside the headlight is crucial. It effectively reduces the internal temperature, ensures stable operation of the headlight, and provides reliable illumination for nighttime driving.

[0003] In traditional production processes, cooling fans are typically assembled manually using a pressing method. This assembly process mainly involves six steps: manually placing the heat sink, manually applying adhesive to the heat sink surface, manually installing the fan, manually installing the fan back cover, pressing with equipment, and finally manually removing the components. This method is not only cumbersome and inefficient, making it difficult to meet the demands of large-scale production, but also prone to inconsistent product quality and a high defect rate due to variations in force and precision during manual operation. Therefore, we propose a vehicle headlight cooling fan installation device to effectively address these drawbacks. Summary of the Invention

[0004] The purpose of this invention is to provide a vehicle headlight cooling fan installation device to solve the problems mentioned in the background art, such as the difficulty in meeting the needs of large-scale production and the instability of product quality caused by the manual pressing method in the prior art.

[0005] The present invention is achieved through the following technical solution: a vehicle headlight cooling fan installation device, including a workbench, the top of the workbench is provided with a turntable that can rotate around its own axis, a plurality of heat sink placement seats are fixed at equal intervals along the circumference at the top edge of the turntable, a stop is fixed on the top of each heat sink placement seat, and a positioning notch adapted to the heat sink is opened on each stop.

[0006] Around the periphery of the turntable, there are heat sink feeding mechanism, glue application mechanism, pressing mechanism and finished product unloading mechanism distributed at intervals along the circumference. The heat sink feeding mechanism, glue application mechanism, pressing mechanism and finished product unloading mechanism are all installed on the top of the worktable.

[0007] Optionally, the heat sink feeding mechanism includes a vibratory feeder installed on the top of the workbench, and a feeding clamping assembly located at the end of the feeding track of the vibratory feeder is installed on the top of the workbench. The feeding clamping assembly is used to clamp the heat sink after it is in place to the heat sink placement seat.

[0008] Optionally, the feeding clamping assembly includes feeding claws and a lifting platform that are spaced apart vertically. The feeding claws are movably disposed on the top of the worktable and can move vertically and horizontally, and the lifting platform is movably disposed on the top of the worktable and can move vertically.

[0009] Optionally, the glue application mechanism includes a glue applicator movably mounted on top of the worktable, the glue applicator being capable of moving up and down and horizontally.

[0010] Optionally, the top of the worktable is fixed with an arc-shaped guide rail arranged along the outer arc surface of the turntable, and the arc-shaped guide rail is located between the glue application mechanism and the pressing mechanism.

[0011] Optionally, the pressing mechanism includes a bracket fixed to the top of the worktable, on which a presser is movably mounted and suspended above the turntable, the presser being able to move up and down.

[0012] Optionally, the pressing mechanism further includes an auxiliary clamp movably disposed on the top of the worktable. The auxiliary clamp is located below the support and can move horizontally. The auxiliary clamp cooperates with the stop to clamp the unpressed fan back cover.

[0013] Optionally, the finished product unloading mechanism includes a movable seat that is movably mounted on the top of the workbench and can move up and down. The top of the movable seat is provided with a rotatable unloading gripper, and an unloading plate located on one side of the movable seat is fixed on the top of the workbench.

[0014] Optionally, the feeding plate is inclined, and a rotating shaft is rotatably connected to the upper end of the feeding plate. A receiving plate is fixed on the rotating shaft, and the receiving plate can rotate along the axis of the rotating shaft.

[0015] Optionally, a rack is fixed to the side of the movable seat, and a gear that meshes with the rack is fixed to the end of the rotating shaft;

[0016] When the movable seat moves downward, the rack and pinion mechanism rotates the receiving plate along the shaft to a horizontal position; when the movable seat returns to its original position, the rack and pinion mechanism rotates the receiving plate along the shaft to a position parallel to the unloading plate.

[0017] Compared with the prior art, the present invention provides a vehicle headlight cooling fan mounting device, which has the following features:

[0018] Beneficial effects:

[0019] 1. This invention, through the configuration of a turntable, a heat sink placement seat, a heat sink feeding mechanism, a gluing mechanism, a pressing mechanism, and a finished product unloading mechanism, allows the heat sink placement seat to sequentially move to each functional station as the turntable rotates. The heat sink feeding mechanism automatically delivers the heat sink to the placement seat, and the gluing mechanism quickly and evenly applies glue to the surface. Subsequently, manual installation of the fan and fan back cover, steps difficult for the equipment to handle, is completed. Following this, the pressing mechanism automatically presses the components together, and finally, the finished product unloading mechanism removes the assembled product. This human-machine collaborative operation mode cleverly utilizes automated equipment for standardized operations while flexibly leveraging the advantages of manual handling of complex processes, significantly improving production efficiency while effectively reducing equipment development and purchase costs.

[0020] 2. By setting up a stop and an arc-shaped guide rail, when the turntable moves the heat sink with the assembled fan and fan back cover toward the pressing mechanism, the stop and the arc-shaped guide rail cooperate to constrain the movement trajectory of the fan and fan back cover, effectively avoiding the shaking and deviation caused by the rotation of the turntable, ensuring that the unpressed fan and fan back cover are stable and do not fall off during the transmission process, and providing a stable and reliable prerequisite for subsequent pressing operations.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] Please see Figures 1 to 11 A vehicle headlight cooling fan installation device includes a workbench 1, on which the headlight cooling fan can be processed and produced. A turntable 2, capable of rotating around its own axis, is mounted on the top of the workbench 1. In this embodiment, a motor is installed on the top of the workbench 1, driving the turntable 2 to rotate intermittently around its own axis, thereby sequentially transferring the heat sink to different workstations to complete each stage of processing. Several heat sink placement seats 3 are fixed at equal intervals along the circumferential direction at the top edge of the turntable 2. The top of each heat sink placement seat 3 has a placement groove, into which the lower end of the heat sink can be placed. When the turntable 2 rotates, it drives the heat sink to flow between workstations. A stop 8 is fixed on the top of each heat sink placement seat 3, and each stop 8 has a positioning notch 9 adapted to the heat sink. This semi-enclosed blocking structure facilitates subsequent manual installation of the fan and fan back cover.

[0035] Around the turntable 2, there are heat sink feeding mechanism 4, glue application mechanism 5, pressing mechanism 6 and finished product unloading mechanism 7 distributed circumferentially. The heat sink feeding mechanism 4, glue application mechanism 5, pressing mechanism 6 and finished product unloading mechanism 7 are all installed on the top of the workbench 1, together forming a complete automated production process.

[0036] Using the above structure, the turntable 2 on the top of the workbench 1 is driven by the motor to rotate intermittently along its own axis, thereby causing each heat sink placement seat 3 to rotate accordingly. When the heat sink placement seat 3 rotates to the work position corresponding to the heat sink feeding mechanism 4, the heat sink feeding mechanism 4 automatically places the heat sink into the placement slot on the top of the heat sink placement seat 3. At the same time, the positioning notch 9 on the stop seat 8, which is adapted to the heat sink, partially surrounds and limits the heat sink, ensuring that the position of the heat sink is fixed.

[0037] Turntable 2 continues to rotate, causing the heat sink holder 3, which contains the heat sink, to move to the corresponding station of the adhesive application mechanism 5. The adhesive application mechanism 5 starts and automatically completes the adhesive application on the surface of the heat sink according to the set program and trajectory, providing an adhesive base for the subsequent installation of the fan and fan back cover.

[0038] After the adhesive is applied, turntable 2 rotates again, transporting the heatsink to a specific position. At this point, with the assistance of the semi-enclosed limit provided by the stop 8, the operator can easily install the fan and fan back cover onto the heatsink. After installation, turntable 2 continues to rotate, moving the unpressed components toward the pressing mechanism 6. The pressing mechanism 6 applies precise pressure to the components, ensuring that the fan, fan back cover, and heatsink are tightly pressed together, completing the crucial assembly step.

[0039] After pressing is completed, turntable 2 continues to rotate, transporting the finished product to the corresponding station of the finished product unloading mechanism 7. The finished product unloading mechanism 7 automatically removes the assembled headlight cooling fan from the heat sink placement seat 3, completing the entire installation process. After unloading, the heat sink placement seat 3 continues to rotate with turntable 2, returning to the heat sink loading station to start the next cycle of operation.

[0040] This invention adopts a human-machine collaborative operation mode, which entrusts the operation links that are difficult for automated equipment to be handled flexibly by humans. It not only gives full play to the advantages of the equipment in efficient repetitive operation, but also makes up for the limitations of the equipment in complex operation. While ensuring the improvement of production efficiency, it effectively controls the equipment research and development and manufacturing costs, and maximizes production benefits.

[0041] The following is a description of the heat sink feeding mechanism 4:

[0042] The heat sink loading mechanism 4 includes a vibratory feeder 401 mounted on the top of the workbench 1 (only the loading track in the vibratory feeder 401 is shown in the figure; other components are not shown). A loading clamping assembly 402 is mounted on the top of the workbench 1 at the end of the loading track of the vibratory feeder 401. The loading clamping assembly 402 is used to clamp the heat sink, once in place, onto the heat sink placement seat 3. Specifically, the loading clamping assembly 402 includes loading claws 4021 spaced vertically apart and a lifting platform 4022. The loading claws 4021 are movably mounted on the top of the workbench 1 and can move vertically and horizontally, allowing for flexible adjustment of the heat sink's height and position. The lifting platform 4022 is movably mounted on the top of the workbench 1 and can move vertically. In this embodiment, it should be noted that the loading claws 4021 can move vertically and horizontally through the cooperation of multiple cylinders. The lifting platform 4022 can move vertically through cylinders.

[0043] Using the above structure, the operator pours the heat sink into the vibratory feeder 401. After pressing the start switch, the vibratory feeder 401 moves the heat sink along the loading track to the end through high-frequency vibration. At this time, the lifting platform 4022 rises upward, supporting the heat sink; then, the loading gripper 4021 grabs the supported heat sink and places it into the heat sink placement seat 3 on the turntable 2. The entire loading process is efficient and automated, laying the foundation for subsequent assembly processes.

[0044] The following is a description of the adhesive application mechanism 5:

[0045] The adhesive application mechanism 5 includes an adhesive applicator 501 movably mounted on top of the workbench 1, capable of vertical and horizontal movement. In this embodiment, it should be noted that the adhesive applicator 501 can achieve vertical and horizontal movement via a linear module. When the heat sink rotates to the adhesive application station, the adhesive applicator 501 applies adhesive to the surface of the heat sink, providing reliable bonding for subsequent assembly.

[0046] After the adhesive is applied, turntable 2 continues to rotate, moving the heat sink to the manual operation station. At this station, the operator installs the fan and fan back cover onto the heat sink in sequence. To prevent the unpressed fan and fan back cover from shaking or falling off due to centrifugal force or vibration during subsequent rotation of turntable 2, the following design is implemented:

[0047] An arc-shaped guide rail 10, arranged along the outer arc surface of the turntable 2, is fixed on the top of the workbench 1. The arc-shaped guide rail 10 is located between the glue application mechanism 5 and the pressing mechanism 6. When the heat sink placement seat 3, which carries the unpressed components, rotates with the turntable 2, the stop 8 and the arc-shaped guide rail 10 form a double limiting structure. The stop 8 semi-encloses and fixes the heat sink through the positioning notch 9, while the arc-shaped guide rail 10 provides lateral constraint from the outside. The two work together to precisely limit the movement range of the fan and the fan back cover, effectively counteracting the inertial force and vibration interference generated by the rotation of the turntable 2, ensuring the stability of the components during transmission, and laying a reliable foundation for the smooth progress of the subsequent pressing process.

[0048] The pressing mechanism 6 is described below:

[0049] The pressing mechanism 6 includes a bracket 601 fixed to the top of the workbench 1, and a press 602 movably mounted on the bracket 601 and suspended above the turntable 2. The press 602 can move up and down. In this embodiment, it should be added that the press 602 can move up and down under the drive of a hydraulic cylinder.

[0050] The pressing mechanism 6 also includes an auxiliary clamp 603 movably disposed on the top of the workbench 1. The auxiliary clamp 603 is located below the bracket 601 and can move horizontally. In this embodiment, the auxiliary clamp 603 can move horizontally under the drive of a cylinder, thereby enabling the auxiliary clamp 603 to cooperate with the stop 8 to clamp the unpressed fan back cover.

[0051] With the above structure, when the turntable 2 transports the heat sink with the assembled fan and rear cover to the pressing station, the auxiliary clamp 603 slides horizontally first, closely engaging with the corresponding stop 8 to firmly clamp the unpressed fan rear cover from both sides, forming a reliable pre-fixed structure. After clamping, the press 602 moves smoothly downward under the strong thrust of the hydraulic cylinder, precisely pressing the fan rear cover with constant pressure to ensure a tight fit between components, guaranteeing assembly quality and effectively preventing damage to parts due to uneven force.

[0052] The following is a description of the finished product feeding mechanism 7:

[0053] The finished product unloading mechanism 7 includes a movable seat 701 movably mounted on the top of the workbench 1 and capable of vertical movement. In this embodiment, the movable seat 701 can move up and down under the drive of a cylinder. A rotatable unloading gripper 702 is provided on the top of the movable seat 701. In this embodiment, the unloading gripper 702 can rotate under the drive of a motor. A unloading plate 703 is fixed on the top of the workbench 1, located on one side of the movable seat 701. When the finished product, after pressing, rotates to the unloading station with the turntable 2, the unloading gripper 702 picks it up, adjusts its angle by rotation, and accurately places it on the unloading plate 703. Subsequently, through the conveying of the unloading plate 703, the finished product is smoothly transferred to the material frame, completing the final stage of the entire production process.

[0054] It is worth mentioning that the feeding plate 703 is tilted, allowing the finished product to slide smoothly into the material frame, improving feeding efficiency. The upper end of the feeding plate 703 is rotatably connected to a rotating shaft 704, and a receiving plate 705 is fixed on the rotating shaft 704. The receiving plate 705 can rotate along the axis of the rotating shaft 704.

[0055] Considering the inclined design of the feed plate 703, if the feed gripper 702 places the finished product directly on it, the gap between the finished product and the feed plate 703 will be relatively large, making it prone to damage due to collision during the fall. Therefore, the receiving plate 705 plays a crucial role: when the feed gripper 702 places the finished product, the receiving plate 705 is in a horizontal position, which can stably support the finished product and prevent it from falling or tilting; after the finished product is properly placed, the receiving plate 705 rotates around the pivot 704 until it is parallel to the feed plate 703, and the finished product can then slowly slide along the receiving plate 705 into the feed plate 703, safely and efficiently completing the feeding process and effectively reducing the finished product damage rate.

[0056] In this embodiment, a rack 706 is fixed to the side of the movable seat 701, and a gear 707 that meshes with the rack 706 is fixed to the end of the rotating shaft 704. When the movable seat 701 moves downward, the rack 706 and the gear 707 work together to rotate the receiving plate 705 to a horizontal position along the rotating shaft 704, providing a stable receiving surface for the finished product. When the movable seat 701 returns to its original position, the rack 706 and the gear 707 work together to rotate the receiving plate 705 to a position parallel to the unloading plate 703 along the rotating shaft 704, ensuring that the finished product can slide safely and smoothly into the material frame, achieving an efficient finished product conveying process.

[0057] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
