Description

Technical Field

[0001] This utility model belongs to the technical field of automotive parts manufacturing equipment, and in particular relates to an assembly device for wiper motor assembly screws. Background Technology

[0002] In the production of wiper motors, the accurate assembly of the assembly screws is one of the key steps to ensure stable motor operation and sealing performance. Traditional assembly processes rely primarily on manual operation, where each screw is manually pressed into the pre-drilled mounting holes on the rubber gasket. This manual assembly method has several drawbacks:

[0003] 1. Low assembly efficiency: Manual assembly is slow and difficult to adapt to the needs of large-scale, high-efficiency production, which affects the overall production progress and cost control of wiper motors.

[0004] 2. Poor assembly consistency: Manual operation makes it difficult to ensure that each assembly screw is pressed in with the same force and depth, which may lead to loose assembly or excessive compression, affecting the quality and reliability of the product.

[0005] 3. High labor intensity: Long-term repetitive manual pressing operations not only easily cause hand fatigue and injury to operators, but also increase occupational health risks and reduce work efficiency and employee satisfaction.

[0006] In view of the above problems, there is an urgent need in the market for a device that can automate, efficiently and accurately complete the assembly of wiper motor assembly screws in order to improve production efficiency, ensure assembly quality and improve the working environment. Utility Model Content

[0007] To address the aforementioned problems in the prior art, this utility model aims to provide an assembly device for wiper motor assembly screws, which solves the problems of low assembly efficiency, poor assembly consistency, and high labor intensity caused by the existing wiper motor assembly screw process relying mainly on manual operation.

[0008] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0009] An assembly device for wiper motor assembly screws is provided, comprising a base and a mounting plate arranged vertically at intervals, with multiple support columns disposed between the base and the mounting plate. The upper end face of the base is provided with a support seat and a positioning seat for supporting and limiting the wiper motor. The mounting plate is provided with a cylinder for communicating with a compressed air source, the tail end of the cylinder is fixedly connected to the lower end face of the mounting plate, the piston rod of the cylinder is connected to a connecting plate, and the lower end face of the connecting plate is provided with multiple pressure heads for assembling assembly screws.

[0010] The working principle of the above-mentioned assembly device for wiper motor combination screws is as follows: In use, firstly, the combination screws are placed into the rubber pads at the mounting holes of the wiper motor, then the wiper motor is placed into the device and positioned by the support and positioning seats to keep the wiper motor stable. Next, the cylinder is activated, the piston rod of the cylinder extends, and the pressure head moves vertically downward under the action of the cylinder to press the combination screws completely into the rubber pads, thus completing the assembly of the wiper motor combination screws. Finally, the wiper motor is removed from the device.

[0011] Furthermore, the wiper motor includes a motor portion and a reducer portion; the motor portion includes a motor housing; multiple combination screws are arranged around the reducer portion, and multiple pressure heads are located on top of the combination screws, with each pressure head matching one-to-one with a combination screw; the top of the support base has a semi-circular groove for mounting the motor housing; the center of the positioning base has a positioning hole, and the output shaft of the reducer portion is located within the positioning hole. When fixing the wiper motor, the motor housing is placed in the semi-circular groove, and the output shaft of the reducer portion is engaged with the positioning hole, ultimately achieving support and limiting of the wiper motor.

[0012] Furthermore, both the base and the mounting plate are rectangular plate structures, and a support column is provided at each of the four corners of the base and the mounting plate. The top and bottom ends of each support column are fixedly connected to the lower end face of the mounting plate and the upper end face of the base, respectively. The four support columns can connect the base plate and the mounting plate together and keep the mounting plate horizontal, avoiding asynchronous pressure heads caused by cylinder tilting or loosening.

[0013] Furthermore, a pressure plate is fixedly connected to the tail end of each pressure head, and each pressure plate is detachably connected to the lower end face of the connecting plate. This design makes the pressure heads easy to replace.

[0014] Furthermore, the upper surface of the mounting plate is provided with a solenoid valve for introducing or discharging gas into the cylinder to drive the piston rod of the cylinder to extend or retract. The solenoid valve is connected to the air passage of the cylinder. The solenoid valve is used to control the flow direction of compressed air in the cylinder's air passage, thereby controlling the extension and retraction of the piston rod of the cylinder.

[0015] Furthermore, two switches for activating the solenoid valve are provided on both sides of the upper end face of the base. When both switches are closed simultaneously, the solenoid valve operates. The switches are used to energize the solenoid valve. Two switches are provided to prevent the cylinder from moving and causing mechanical injury if the operator accidentally touches one of the switches.

[0016] Furthermore, a pressure regulating valve is provided between the cylinder and the compressed air source, and the pressure regulating valve is fixedly connected to one side of the mounting plate. The pressure regulating valve is used to adjust the input air pressure. If the air pressure is too high, it may deform the mounting position of the wiper motor; if the air pressure is too low, the assembly screws cannot be assembled in place.

[0017] Furthermore, the upper surface of the mounting plate is provided with a time delay controller electrically connected to the solenoid valve. The time delay controller is used to control the opening time of the solenoid valve, and the pressure holding time can be set by the time delay controller to avoid insufficient pressure holding causing the combination screw to fail to be assembled properly due to the rebound of the rubber pad.

[0018] Furthermore, two safety light curtains are installed between the base and the mounting plate. Both safety light curtains are electrically connected to the delay controller. The cylinder, support base, and positioning base are all located within the area enclosed by the two safety light curtains. The safety light curtains are used to protect the operator. If the operator puts their hand into the area within the safety light curtains during the movement of the cylinder piston rod, an emergency power cut-off will occur, the solenoid valve will close, and the cylinder piston rod will stop moving, preventing the operator's hand from being crushed.

[0019] Compared with the existing screw assembly process for wiper motors, the advantages of this utility model are as follows:

[0020] This invention discloses an assembly device for wiper motor assembly screws. The semi-automated assembly process significantly shortens the assembly cycle of a single wiper motor, facilitating large-scale mass production and improving overall production efficiency. Precise positioning and clamping, along with a pneumatic pressing mechanism, effectively avoids the problems of incomplete or over-assembly that occur with manual assembly, ensuring assembly consistency and improving the product quality of the wiper motor. The semi-automated operation reduces manual intervention, avoids the health hazards of prolonged repetitive labor, improves the comfort and safety of the working environment, and solves the problems of low assembly efficiency, poor assembly consistency, and high labor intensity inherent in existing wiper motor assembly screw processes that rely heavily on manual operation.

However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All inventions utilizing the concept of this utility model are protected.

[0026] like Figures 1-3 As shown, this utility model provides an assembly device for wiper motor assembly screws, which includes a vertically spaced base 1 and a mounting plate 2. Multiple support columns 3 are arranged between the base 1 and the mounting plate 2. The upper surface of the base 1 is provided with a support seat 4 and a positioning seat 5 for supporting and limiting the wiper motor 9. A cylinder 6 for communicating with a compressed air source is provided on the mounting plate 2. The tail end of the cylinder 6 is fixedly connected to the lower surface of the mounting plate 2. The piston rod of the cylinder 6 is connected to a connecting plate 7. The lower surface of the connecting plate 7 is provided with multiple pressure heads 8 for assembling assembly screws 10. Specifically, a pressure plate 13 is fixedly connected to the tail end of each pressure head 8, and each pressure plate 13 is detachably connected to the lower surface of the connecting plate 7. This design makes the pressure heads 8 easy to replace.

[0027] In this embodiment, the wiper motor 9 includes a motor portion and a reducer portion 902. The motor portion includes a motor housing 901. Multiple combination screws 10 are arranged around the reducer portion 902, and multiple pressure heads 8 are located on top of the combination screws 10, with each pressure head 8 matching one-to-one with a combination screw 10. The top of the support base 4 has a semi-circular groove 11 for mounting the motor housing 901. The center of the positioning base 5 has a positioning hole 12, and the output shaft of the reducer portion 902 is located within the positioning hole 12. When fixing the wiper motor 9, the motor housing 901 is placed in the semi-circular groove 11, and the output shaft of the reducer portion 902 is engaged with the positioning hole 12, ultimately supporting and limiting the wiper motor 9.

[0028] As a specific arrangement of the base 1 and mounting plate 2, both the base 1 and mounting plate 2 are rectangular plate structures. A support column 3 is provided at each of the four corners of the base 1 and mounting plate 2. The top and bottom ends of each support column 3 are fixedly connected to the lower end face of the mounting plate 2 and the upper end face of the base 1, respectively. The four support columns reliably connect the base plate and mounting plate 2 together and keep the mounting plate 2 level, preventing the pressure heads 8 from becoming asynchronous due to the cylinder 6 being tilted or loose.

[0029] As a specific control method for the extension and retraction of the piston rod of cylinder 6, the upper end face of the mounting plate 2 is provided with a solenoid valve 14 for introducing or discharging gas into cylinder 6 to drive the extension and retraction of the piston rod of cylinder 6. The solenoid valve 14 is connected to the air passage of cylinder 6. The solenoid valve 14 is used to control the flow direction of compressed air in the air passage of cylinder 6, thereby controlling the extension and retraction of the piston rod of cylinder 6.

[0030] Specifically, two switches 15 are provided on both sides of the upper end face of the base 1 for activating the solenoid valve 14. When both switches 15 are closed simultaneously, the solenoid valve 14 operates. The switches 15 are used to energize the solenoid valve 14. There are two switches 15 to prevent the cylinder 6 from moving and causing mechanical injury if the operator accidentally touches one of the switches 15.

[0031] Preferably, but not limited to, a pressure regulating valve 16 is provided between the cylinder 6 and the compressed air source, and the pressure regulating valve 16 is fixedly connected to one side of the mounting plate 2. The pressure regulating valve 16 is used to regulate the input air pressure. If the air pressure is too high, it may deform the mounting position of the wiper motor 9; if the air pressure is too low, the combination screw 10 cannot be assembled in place.

[0032] The upper surface of the mounting plate 2 is provided with a delay controller 17 electrically connected to the solenoid valve 14. The delay controller 17 is used to control the opening time of the solenoid valve 14. The pressure holding time can be set by the delay controller 17 to avoid insufficient pressure holding causing the combination screw 10 to fail to be assembled properly due to the rebound of the rubber pad.

[0033] To improve the safety of the entire assembly device, two safety light curtains 18 are installed between the base 1 and the mounting plate 2. Both safety light curtains 18 are electrically connected to the delay controller 17. The cylinder 6, support 4, and positioning seat 5 are all located within the area enclosed by the two safety light curtains 18. The safety light curtains 18 are used to protect the operator. During the movement of the piston rod of the cylinder 6, if the operator puts their hand into the area within the safety light curtain 18, an emergency power cut-off will occur, the solenoid valve 14 will close, and the piston rod of the cylinder 6 will stop moving, preventing the operator's hand from being crushed.

[0034] The working principle of the assembly device for wiper motor combination screws in this utility model is as follows: In use, firstly, the combination screws 10 are placed into the rubber pads at the mounting holes of the wiper motor 9, and then the wiper motor 9 is placed into the device. The support seat and positioning seat 5 are used to position the wiper motor 9 to keep it stable. Then, the two switches 15 are pressed at the same time to start the cylinder 6. The piston rod of the cylinder 6 extends, and the pressure head 8 moves vertically downward under the action of the cylinder 6, pressing the combination screws 10 completely into the rubber pads, thus completing the assembly of the wiper motor 9 combination screws 10. Finally, the wiper motor 9 is removed from the device.

[0035] In summary, the assembly device for wiper motor assembly screws of this utility model significantly shortens the assembly cycle of a single wiper motor 9 through a semi-automated assembly process, which is conducive to large-scale mass production and improves overall production efficiency. Precise positioning and clamping, along with the pneumatic pressing mechanism, effectively avoids the problems of incomplete or over-assembly caused by manual assembly, ensuring assembly consistency and improving the product quality of the wiper motor 9. The semi-automated operation reduces manual intervention, avoids the harm to the operator's health caused by prolonged repetitive labor, improves the comfort and safety of the working environment, and solves the problems of low assembly efficiency, poor assembly consistency, and high labor intensity inherent in existing wiper motor 9 assembly screw 10 processes that mainly rely on manual operation.
