Description

An automatic hook arrangement device Technical Field

[0001] This utility model relates to the field of automatic feeding, specifically to an automatic hook arrangement device. Background Technology

[0002] In modern automotive manufacturing, windshield wipers are one of the key components ensuring driving safety and clear visibility. During the installation and maintenance of windshield wipers, the wiper hook, as a crucial component connecting the wiper to the car's glass cleaning system, plays a vital role. Wiper hooks are typically used to securely fix the wiper arm to the wiper head, thus requiring extremely high precision in manufacturing and automated production. Currently, hook production on the market often relies on traditional manual operation and assembly, which not only increases production costs but also reduces efficiency. Furthermore, due to the complex shape and small size of the hooks, the high precision requirements of manual loading, sorting, and installation increase the difficulty and error rate of the manufacturing process. Therefore, hook production equipment with low automation levels struggles to meet the modern automotive industry's demands for efficiency, quality, and production speed.

[0003] A search revealed a Chinese patent document disclosing a wiper assembly auxiliary device [Application No.: 202421033908.8, Publication No.: CN222449120U]. This wiper assembly auxiliary device includes a control device, a turntable mechanism, a pressing mechanism, and multiple limiting fixtures. The turntable mechanism includes a turntable and a first driving device for driving the turntable to rotate. Multiple limiting fixtures are provided on the upper surface of the turntable along its circumference. Although this device can assist in wiper assembly, it has a low degree of automation and cumbersome operation procedures, making it unsuitable for automation and mass production. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an automatic hook arrangement device.

[0005] An automatic hook arranging device, characterized in that it includes a rotating device, a structural frame and two feeding cylinders, wherein the rotating device is mounted on the structural frame and the feeding cylinders are both mounted on the structural frame;

[0006] The rotary device includes a hook frame, a hook indexing plate, a rotating device, and a horizontal displacement device. The hook frame is evenly and equidistantly installed on the hook indexing plate. The hook indexing plate is movably installed on the rotating device. The rotating device is installed on the horizontal displacement device. The horizontal displacement device is installed on the top of the structural frame.

[0007] Each feeding cylinder includes a barrel body, a vibrating plate, and a slide rail. The vibrating plate is installed on the top of the barrel body, and the slide rail is located at the discharge port of the vibrating plate. The inlet end of the vibrating plate is slightly higher than the outlet end. Preferably, feeding cylinders are respectively provided on both sides of the rotary device.

[0008] Based on the above technical solution, this layout design is designed according to the principle of dual-channel feeding in industrial automation. It aims to achieve flexible switching of multiple operating modes through symmetrically distributed feeding cylinders. The left and right feeding cylinders can be started simultaneously. The high-frequency vibration of the vibratory feeder will orderly transport the hooks to the slide rail and slide them into the hook frame of the rotary device along the inclined track of the slide rail. In addition, the two feeding cylinders can also operate independently and load different types of hooks respectively. Through the program preset of the control system, the rotary device can automatically switch the feeding source according to the production needs, thereby achieving the flexible production goal of multiple varieties mixed arrangement on the same equipment. Furthermore, the design also has a redundancy fault tolerance function. When one feeding cylinder stops operating due to failure or maintenance, the other feeding cylinder can still maintain the basic feeding capacity.

[0009] Preferably, an adjustment bracket is provided between the feeding cylinder and the structural frame.

[0010] Through the above technical solution, this design allows the feeding cylinder to be adjusted in height, position, and other aspects under different working conditions. The existence of the adjusting bracket effectively enhances the flexibility and adaptability of the equipment, enabling operators to adjust the position of the feeding cylinder according to actual needs, thereby optimizing the material flow path and improving production efficiency. At the same time, the stability and precision of the adjusting bracket ensure the stability of the feeding cylinder during the adjustment process, preventing material blockage or equipment failure caused by improper positioning, further improving the reliability of the system and its stability during long-term operation.

[0011] Preferably, the adjusting bracket includes a base, a lifting rod, a mounting platform, and a movable buckle. The lifting rod is installed on top of the base, the mounting platform is installed on top of the lifting rod, and the movable buckle is installed on top of the mounting platform.

[0012] Through the above technical solutions, the stability of the base provides the basic support for the bracket, ensuring that the equipment remains stable during operation; the installation of the lifting rod allows the bracket to be adjusted vertically, thereby changing the height of the feeding cylinder to adapt to different operating needs; the installation platform provides a stable placement surface for the feeding cylinder, ensuring that the feeding cylinder will not tilt or shift during adjustment; the design of the movable buckle further improves the convenience of adjustment, allowing operators to quickly lock the adjusted settings and avoid positional changes caused by vibration or external factors.

[0013] Preferably, a detector is provided on the side of the feeding cylinder.

[0014] With the above technical solution, detector 1 is installed in the upper middle part of the inside of the barrel, with the detection direction facing the stacking area of ​​the material inside the barrel. Detector 1 can detect the number of hooks inside the barrel in real time. When the material is lower than the preset threshold, it sends a low material warning signal to the control system to prompt the operator to replenish the material. It can also identify the arch blockage formed by the material being stuck to each other, trigger the enhanced vibration mode of the vibrating plate to break the blockage structure and restore the material flow. If the abnormal state of the material is continuously detected, it sends a stop command to the control system and activates the audible and visual alarm device.

[0015] Preferably, a detector 2 is installed at the feed inlet of the slide rail.

[0016] Through the above technical solution, detector 2 is installed on both sides of the feed end of the slide rail to form a through-beam detection area. Detector 2 can count the number of hooks passing through the feed inlet per unit time, and adjust the vibration frequency of the vibratory feeder in combination with the preset value to achieve dynamic balance of the feeding rate. At the same time, it can detect whether the orientation of the hooks when entering the slide rail is correct. If a hook in the opposite direction or tilted is detected, an alarm is triggered. If no hooks pass through the feed inlet continuously, it is determined that the slide rail is blocked or the vibratory feeder is faulty, and the equipment operation is immediately stopped and an alarm is triggered.

[0017] Preferably, a detector is installed at the material outlet of the slide rail.

[0018] Through the above technical solution, detector three is installed on both sides of the slide rail discharge end to form a through-beam detection area. Detector three is used to monitor whether the hook completely leaves the slide rail and falls accurately into the designated position of the hook frame. At the same time, by detecting the number of times the hook passes through the discharge port, the number of qualified hooks is accumulated and automatically compared with the preset production quantity to achieve the purpose of counting.

[0019] Preferably, a detector four is provided on the side of the rotary device.

[0020] Through the above technical solution, detector four is installed on the side of the rotating device. Detector four is used to collect the actual rotation angle of the rotating device in real time and compare it with the target angle set by the control system. If the deviation exceeds the allowable range, the servo motor is triggered to fine-tune the rotation position. When the equipment starts or resets, the hook frame is driven to perform reference position calibration to ensure that the initial angle is consistent with the program setting.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. This automatic hook arranging device achieves fully automated operation through synchronous feeding from dual feeding cylinders, multi-directional movement of the rotary device, and closed-loop feedback from the detector group. The dual feeding cylinder design supports parallel feeding, and combined with the directional conveying of the vibratory feeder and the tilting guidance of the slide rail, it ensures that the hooks continuously and stably enter the rotary device. The rotation and horizontal displacement functions of the rotary device work in tandem, and the hook frame automatically ejects after being fully loaded, reducing manual intervention. The detector group covers the entire process of feeding, conveying, hanging, and transferring, monitoring the material balance, flow status, hanging quality, and positional accuracy in real time, significantly reducing the production error rate. It is suitable for high-precision, high-volume continuous production scenarios.

[0023] 2. The equipment, through its modular design and flexible adjustment capabilities, is compatible with mixed or sequential arrangements of multiple types of hooks, meeting diverse production needs. The dual feeding cylinders can operate independently or synchronously, supporting efficient feeding of a single product category and flexible switching between multiple product categories. The lifting and horizontal fine-tuning functions of the adjustable support can adapt to the conveying needs of hooks of different weights and sizes, significantly reducing changeover time and modification costs.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please refer to Figures 1 to 4. This utility model provides a technical solution:

[0031] Example 1:

[0032] This embodiment describes the automatic feeding and arrangement process of the hook automatic arrangement equipment for hooks of the same type. When the equipment starts, both feeding cylinders 3 are loaded with hooks of the same specification. The randomly arranged hooks in the cylinders are oriented and conveyed forward to the slide rail 303 by the vibrating plate 302. The discharge port of the slide rail 303 is connected to the hook frame 101 of the rotating device 1. After the hook slides out of the slide rail 303, it is naturally suspended on the support rod of the hook frame 101 by gravity. When the detector 4 504 detects that a single support rod of the hook frame 101 is full of hooks, it sends a signal to the control system. The rotating device 103 then drives the hook frame 101 to rotate a certain angle, so that the next unloaded support rod moves directly below the discharge port of the slide rail 303 to receive the subsequent hooks.

[0033] During this process, detector 2 502 is installed on both sides of the feed inlet of slide rail 303 to continuously monitor the flow status of the hook entering slide rail 303. If the flow of the hook is interrupted, detector 2 502 immediately sends an abnormal signal to the control system. Detector 3 503 at the discharge outlet of slide rail 303 monitors the falling path of the hook in real time. If the hook fails to hang accurately on the support rod, detector 3 503 sends an abnormal signal to the control system and stops rotating device 103.

[0034] Once all the support rods of the hook frame 101 are fully loaded with hooks, the detector 501 counts the number of hooks that have been delivered and compares it with a preset value. After confirming that the material is full, it sends a command to the horizontal displacement device 104. The horizontal displacement device 104 drives the rotary device 1 to move horizontally as a whole. At this time, the empty hook indexing plate 102 can be replaced with the filled hook indexing plate 102.

[0035] If detector 501 detects insufficient hook clearance or material accumulation in the feeding cylinder 3 on one side during operation, it immediately sends an abnormal signal to the control system, stops feeding on that side, and increases the feeding intensity of the feeding cylinder 3 on the other side to maintain overall production efficiency.

[0036] Example 2:

[0037] This embodiment describes the mixed feeding and sequential arrangement process of two different types of hooks. The left feeding cylinder 3 is loaded with the heavier hook one, and the right feeding cylinder 3 is loaded with the lighter hook two. The two slide rails 303 are independently adjusted by the adjusting bracket 4: the left slide rail 303 is tilted at a lower angle to reduce the sliding speed due to the greater weight of hook one; the right slide rail 303 is tilted at a higher angle to accelerate the conveying efficiency of hook two. The vibratory feeder 302 is activated alternately according to the instructions of the control system. When hook one needs to be fed, the left vibratory feeder 302 is activated, and hook one slides out along the slide rail 303 and is suspended on the support rod of the hook frame 101; similarly, when the right vibratory feeder 302 is activated, hook two is suspended on the support rod 101.

[0038] Detector 3 503 is installed on both sides of the discharge end of slide rail 303. It can identify hook 1 and hook 2. If hook 1 accidentally enters the conveying channel of hook 2, detector 3 503 immediately sends an abnormal signal to the control system. When the support rod 101 of hook frame 101 is hooked, the rotating device 103 drives the hook frame 101 to rotate, so that the unloaded side support rod is aligned with the discharge port of slide rail 303 to continue feeding.

[0039] When the hook frame 101 is fully loaded, the detector 501 confirms the completion status by counting the consumption of the two side feeding cylinders 3. The horizontal displacement device 104 drives the rotary device 1 to move horizontally, moving the fully loaded hook frame 101 out of the feeding position. At this time, the empty hook indexing plate 102 can be used to replace the filled hook indexing plate 102.
