Description

Technical Field

[0001] This utility model relates to the technical field of wiper blade production equipment, specifically an automated wiper blade production line. Background Technology

[0002] Windshield wipers are a common car accessory. When a car is driving on the road, various dust, mud, or sewage may stick to the windshield, affecting the driver's vision. By wiping the windshield surface with wipers, these impurities can be removed, making the windshield surface cleaner. The wipers are equipped with wiper blades for removing impurities from the windshield.

[0003] A search revealed a patent, CN216804482U, which discloses an intelligent production line for silicone wiper blades. This line includes a control system and sequentially connected extrusion, drying, and curing units. The extrusion unit comprises a first screw extruder, a second screw extruder, and an extrusion driver. The extrusion driver is connected to both the first and second screw extruders. The curing unit includes a curing chamber, a conveyor belt, and a servo motor. The conveyor belt is located inside the curing chamber, and the servo motor is connected to the conveyor belt. The control system includes a servo controller, a touchscreen display, a frequency converter, and an encoder. The touchscreen display is connected to the servo controller, the encoder is mounted on the extrusion driver, and the frequency converter is connected to the encoder via a built-in PG card. The servo motor is connected to the servo controller. This intelligent production line, through its control system, automatically matches the conveyor speed of the conveyor belt in the curing unit with the extrusion speed of the extrusion unit, thereby ensuring normal equipment operation and improving production efficiency.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In the prior art, after the wiper blades are extruded and shaped, they need to be cut to length according to different product specifications. However, in the aforementioned comparative document, after the wiper blades are produced, they need to be transported to another station for length cutting using a conveyor device. During the conveying process, the elastic wiper blades may shift, requiring operators to straighten and cut them again, which reduces the efficiency of wiper blade production. Therefore, there is an urgent need in the field to improve the automated production line for wiper blades to solve the defects of the prior art. Utility Model Content

[0025] 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.

[0026] Please see Figures 1-4 An automated production line for wiper blades includes an extrusion device 1, a connecting support platform 2, and a conveying device 3 arranged sequentially. The extrusion device 1 has several extrusion cylinders 13 adapted to the connecting support platform 2 on one side. The connecting support platform 2 has a top plate 4 on its upper part, and a shaping device 5 and a vulcanizing device 6 for shaping and vulcanization are located on the top plate 4. The connecting support platform 2 has several limiting side plates 7 adapted to the extrusion cylinders 13, extending to the upper part of the conveying device 3. Each pair of limiting side plates 7 is electrically connected to each other and has an extension function. The first telescopic device 8 and the second telescopic device 9 have a shrinking effect. The first telescopic device 8 is located above the conveying device 3. The lower end of the first telescopic device 8 is provided with a fixed-length plate 10 that matches the spacing between the two limiting side plates 7. The fixed-length plate 10 is provided with a sensing device 11 for sensing on the side near the connecting support platform 2. The second telescopic device 9 is located above the connecting support platform 2 and its telescopic end is provided with a cutting blade 12 for cutting. A cutting groove 26 is provided through the connecting support platform 2. The cutting groove 26 matches a number of cutting blades 12 and penetrates the connecting support platform 2.

[0027] Specifically, rubber raw material is fed into extrusion device 1 and heated to a molten state. Driven by a servo motor, the rubber raw material is extruded through extrusion cylinder 13. After being heated and extruded by extrusion device 1, the rubber raw material is guided by limiting side plates 7 into connecting support platform 2. The distance between the two limiting side plates 7 is adapted to the size of the wiper blade to ensure that the wiper blade's position does not shift. The extruded wiper blade then passes through shaping device 5 and vulcanizing device 6. Both shaping device 5 and vulcanizing device 6 have pipes at their lower parts that communicate with the two limiting side plates 7. The shaping device 5 and vulcanizing device 6 shape and vulcanize the wiper blade. The shaping device 5 and vulcanizing device 6 are existing known technologies, such as patent publication number CN216804482U, which discloses an intelligent production line for silicone wiper blades. Subsequently, the wiper blade is guided to… On the conveyor device 3, which is a commonly used conveyor belt in the prior art, the transmission efficiency of the conveyor device 3 is equal to the wiper blade extrusion efficiency. The telescopic end of the first telescopic device 8 drives the fixed-length plate 10 to move down. When one end of the wiper blade is guided to the position of the sensing device 11 (such as the Omron E2E-X5ME1 proximity sensor), the sensing device 11 senses it and starts the second telescopic device 9. The telescopic end of the second telescopic device 9 drives the cutter 12 to move down, and works with the cutting groove 26 to cut the wiper blade to the specified length. The cutter 12 and the fixed-length plate 10 move up at the same time. At this time, the conveyor device 3 accelerates the transmission and quickly transports the cut wiper blade to the designated storage position. The fixed-length plate 10 moves down again. After the wiper blade is extruded and shaped by the above production equipment, it is then cut to the specified length, which improves the production efficiency of the wiper blade.

[0028] As a technical optimization of this utility model, a first fixing plate 16 is provided between every two limiting side plates 7, and a first telescopic device 8 is fixedly installed on the first fixing plate 16. Two symmetrical adjusting blocks 14 are provided on the lower side of the first fixing plate 16. An adjusting groove 15 adapted to the adjusting block 14 is opened on the upper part of the limiting side plate 7. A first fixing threaded post 17 penetrating the first fixing plate 16 is fixedly installed on the upper part of the adjusting block 14. A first limiting nut 18 is threadedly connected to the side of the first fixing threaded post 17. The adjusting groove 15 is opened through one end of the limiting side plate 7. A scale plate 25 is provided on the side of each limiting side plate 7. The scale plate 25 has a scale.

[0029] Specifically, when it is necessary to cut wiper blades of different lengths, the position of the first fixing plate 16 is adjusted by moving the adjusting block 14 within the adjusting groove 15. Then, the first limiting nut 18, which is threaded to the side of the first fixing thread post 17, is tightened to position the first fixing plate 16. The adjusting block 14 can slide out of the adjusting groove 15, which facilitates the installation of the first fixing plate 16. This allows for the cutting of wiper blades of different lengths, improving the applicability of the overall device. Furthermore, the graduated plate 25 on the side of the limiting side plate 7 facilitates precise adjustment of the position of the length plate 10.

[0030] As a technical optimization of this utility model, a second fixing plate 19 for installing the second telescopic device 9 is provided between every two limiting side plates 7. A second fixing threaded post 20 that penetrates the second fixing plate 19 is fixedly installed on the upper part of each of the two limiting side plates 7. A second limiting nut 21 is threadedly connected to the side of the second fixing threaded post 20. A plug-in block 22 is fixedly installed on the upper part of the cutter 12. A plug-in groove 23 that matches the plug-in block 22 is opened at the telescopic end of the second telescopic device 9. A locking bolt 24 that is threadedly connected to the side of the plug-in block 22 is passed through the telescopic end of the second telescopic device 9.

[0031] Specifically, when installing the cutter 12, the upper plug block 22 of the cutter 12 is inserted into the plug slot 23, one end of the locking bolt 24 passes through the end of the second telescopic device 9, and its end is threaded to the side of the plug block 22, which facilitates the installation or later replacement of the cutter 12. The second fixing plate 19 is sleeved on the side of the two second fixing threaded posts 20, and the second limit nut 21 is threaded to the side of the second fixing threaded post 20 and locked, thus installing and fixing the second telescopic device 9.
