Description

Technical Field

[0001] This utility model relates to the field of windshield wiper assembly technology, specifically an assembly device for automotive windshield wipers. Background Technology

[0002] A car windshield wiper is a device installed on the outside of a vehicle's windshield to clean the glass. It consists of a support arm, a clip, and a wiper blade. The wiper blades move in a fan shape to clean impurities and rainwater from the glass, improving the driver's safety when driving in rainy or other weather conditions.

[0003] The clips in a windshield wiper primarily serve a connecting and securing function. During production, automated production lines assemble the clips. In the assembly process, mounting molds are installed on the outside of a rotating disc according to the size of the clip. During operation, multiple sets of gripping cylinders work together to move the necessary components for clip assembly into the mounting mold. The cylinders then press the clips together. After assembly, the clips are moved to an external collection box via a conveyor on the other side. Different types of clips require different mounting mold structures. During installation, the mounting holes on the mold are aligned with the mounting holes on the rotating disc, and then the mold is secured with multiple sets of bolts. Multiple mounting molds are typically installed on the outside of a rotating disc for continuous assembly. Therefore, changing mounting molds requires workers to disassemble and reinstall each mold individually, making the installation process somewhat cumbersome.

[0004] To address these issues, we provide a mounting device for automotive windshield wipers. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This utility model proposes an assembly device for automotive windshield wipers, which solves the problem of troublesome installation of mounting molds through the cooperation between the top plate, pressure plate and control plate.

[0007] Technical solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: an assembly device for a car windshield wiper, comprising a support platform, a fixing ring installed inside the support platform, a rotating shaft rotatably connected inside the fixing ring, a rotating disk detachably connected to one end of the rotating shaft, an installation hole opened inside the rotating disk, an installation block slidably connected inside the installation hole, and an installation mold detachably connected to the outer surface of the installation block;

[0009] The rotating shaft has multiple sets of fixing grooves inside. The fixing shaft is fixedly installed on the inner wall of the fixing groove. The outer surface of the fixing shaft is rotatably connected to a connecting ring. The outer surface of the connecting ring is fixedly installed with a fixing plate. The outer surface of the fixing plate is fixedly installed with a pressure plate and a control plate respectively.

[0010] An electric push rod is installed inside the fixed shaft, and a top plate is fixedly installed at the output end of the electric push rod.

[0011] Furthermore, the mounting holes are arranged in a ring array inside the rotating disk, and the lower surface of the mounting mold is in contact with the upper surface of the rotating disk.

[0012] Furthermore, the fixing grooves are arranged in a ring array inside the rotating shaft, the fixing shaft is located near the bottom of the fixing grooves, and the pressure plate and control plate are arranged in opposite directions outside the fixing plate.

[0013] Furthermore, the pressure plate, control plate, and fixing plate are in an S-shaped structure, with the control plate located above the pressure plate and the upper surface of the top plate in contact with the lower surface of the pressure plate.

[0014] Furthermore, the mounting block has a positioning hole inside, and the outer surface of the control board is slidably connected to the inside of the positioning hole.

[0015] Furthermore, a spring is fixedly installed on the inner wall of the rotating shaft, and the other end of the spring is fixedly installed on the outer surface of the pressure plate. The spring and the top plate are arranged in opposite directions outside the pressure plate.

[0016] (iii) Beneficial effects:

[0017] Compared with existing technologies, this automotive wiper assembly has the following advantages:

[0018] I. The assembly device for this automotive wiper, through the cooperation of the top plate, pressure plate, and control plate, allows the mounting mold to be limited outside the mounting hole by the mounting block. At this time, the top plate is driven to move upward by the electric push rod. After the top plate contacts the pressure plate, it continues to move. At this time, the pressure plate drives the control plate to rotate under the action of the fixed shaft. After the control plate rotates, it can enter the interior of the mounting block and apply downward pressure to the mounting block. By controlling multiple sets of pressure plates through the top plate, multiple sets of mounting molds can be fixed simultaneously, and vice versa, multiple sets of mounting molds can be quickly disassembled. The installation process does not require the use of a large number of fixing bolts, making the installation more convenient. It realizes the quick fixing and replacement of the mounting mold during the snap-fit ​​assembly process, making it convenient for the installation and disassembly of the mounting mold.

[0019] 2. The assembly device of this vehicle windshield wiper is equipped with components such as springs. The springs can automatically reset the pressure plate and apply a downward pushing force to the pressure plate. When the top plate and the pressure plate are no longer in contact, the spring pushes the pressure plate to rotate in the opposite direction. At this time, the positioning plate can disengage from the internal connection of the positioning hole and automatically release the fixing of the mounting block, which facilitates the disassembly of the mounting mold.

[0028] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: an assembly device for a car windshield wiper, including a support platform 1, a fixing ring 2 installed inside the support platform 1, a rotating shaft 3 rotatably connected inside the fixing ring 2, a rotating disk 4 detachably connected to one end of the rotating shaft 3, an installation hole 5 opened inside the rotating disk 4, an installation block 6 slidably connected inside the installation hole 5, an installation mold 7 detachably connected to the outer surface of the installation block 6, the installation holes 5 are arranged in a circular array inside the rotating disk 4, the lower surface of the installation mold 7 contacts the upper surface of the rotating disk 4, a conveyor belt component and multiple sets of control cylinders are installed outside the support platform 1, when one set of control cylinders works, it can move the buckle component on the conveyor belt into the interior of the installation mold 7 through the suction cup installed at the output end, and through the rotation The external annular mounting control cylinder of the rotating disc 4 can place the parts required for assembling the wiper clip into the mounting mold 7 in sequence. The control cylinder can also apply downward pressure to the clip, which can press and assemble the clip. Then, through a set of control cylinders and suction cups on the other side, the assembled clip can be sucked out from the outside of the mounting mold 7. The sucked-out clip can be moved to the collection box on one side of the support platform 1 via the slide rail. The mounting mold 7 is connected to the mounting block 6 by fixing bolts. When the mounting block 6 enters the mounting hole 5, the horizontal position of the mounting mold 7 is limited. A fixing frame and a control motor are installed inside the support platform 1. The rotating disc 4 can be controlled to rotate cyclically at the required angle by the control motor and the external controller.

[0029] Multiple sets of fixing grooves 8 are opened inside the rotating shaft 3. Fixing shafts 9 are fixedly installed on the inner wall of the fixing grooves 8. The fixing grooves 8 are arranged in a ring array inside the rotating shaft 3. The fixing shafts 9 are located near the bottom of the fixing grooves 8 and at one end of the fixing grooves 8. Both ends of the fixing shafts 9 are connected to the inner wall of the fixing grooves 8 by welding.

[0030] A connecting ring 10 is rotatably connected to the outer surface of the fixed shaft 9. A fixed plate 11 is fixedly installed on the outer surface of the connecting ring 10. A pressure plate 12 and a control plate 13 are fixedly installed on the outer surface of the fixed plate 11. The fixed plate 11 can be connected and fixed through the connecting ring 10. The pressure plate 12 and the control plate 13 are arranged in opposite directions outside the fixed plate 11. The pressure plate 12, the control plate 13 and the fixed plate 11 form an S-shaped structure. The control plate 13 is located above the pressure plate 12. The control plate 13 and the pressure plate 12 can rotate around the fixed shaft 9. When one end of the pressure plate 12 moves down, one end of the control plate 13 moves up, and vice versa. The rotation of one end of the pressure plate 12 can control one end of the control plate 13.

[0031] A spring 17 is fixedly installed on the inner wall of the rotating shaft 3. The other end of the spring 17 is fixedly installed on the outer surface of the pressure plate 12. The spring 17 and the top plate 15 are arranged in opposite directions on the outside of the pressure plate 12. Multiple sets of limiting rods are installed on the inner wall of the rotating shaft 3 and the outer surface of the pressure plate 12 and are in contact with each other. The multiple sets of limiting rods play a role in assisting the limiting of the spring 17, which can prevent the spring 17 from bending and failing due to its own elasticity.

At this time, the top plate 15 will contact the lower surface of the pressure plate 12 and push one end of the pressure plate 12 to move upward. When one end of the pressure plate 12 moves upward, one end of the control plate 13 moves downward. At this time, the control plate 13 can enter the inside of the positioning hole 16 and apply downward pressure to the mounting block 6, which can quickly fix the mounting block 6. When the top plate 15 moves downward, the spring 17 can push one end of the pressure plate 12 to move downward. At this time, the control plate 13 disengages from the inside of the positioning hole 16 and can automatically release the fixation of the mounting block 6.

[0033] Working principle: When installing the mounting mold 7, the mounting block 6 is placed into the mounting hole 5. At this time, the top plate 15 is moved upward by the electric push rod 14. After the top plate 15 contacts the pressure plate 12, one end of the pressure plate 12 can be moved upward. At this time, one end of the control plate 13 will move downward and enter the positioning hole 16. The control plate 13 can apply downward pressure to the mounting block 6, which can fix multiple sets of mounting molds 7 at the same time.

[0034] When disassembling and installing mold 7, control the top plate 15 to move down. At this time, spring 17 can push one end of pressure plate 12 to move down, and one end of control plate 13 will move up and disengage from the inside of positioning hole 16. At this time, the limit on mounting block 6 can be released.
