Description

Technical Field

[0001] The present invention relates to the technical field of window regulator assembly devices, and more particularly to a slider assembly device for automotive window regulators. Background Art

[0002] Automotive window regulators are an important part of the automotive door and window system, and their performance directly affects the smoothness and sealing of window lifting. As a key component of the window regulator, the slider is responsible for clamping and guiding the movement of the glass. At present, the production of automotive window regulators is developing towards automation and high efficiency, but there are still many manual interventions in the slider assembly process, which restricts the overall assembly efficiency and the consistency of assembly quality.

[0003] With the continuous increase in automotive production, the requirements for the efficiency and accuracy of slider assembly are also getting higher and higher. An existing slider includes a plastic block, two metal sheets, and a shock-absorbing block. The two metal sheets are assembled and connected by bolts. The plastic block is inserted and assembled with one metal sheet, and the shock-absorbing block is installed on the plastic block. At present, there are mainly two common slider assembly methods in the industry: one is completely manual assembly, where operators manually complete the positioning, clamping, and fixing of the slider; the other is semi-automatic assembly, where simple jigs assist manual operations to complete part of the work. The advantage of completely manual assembly is high flexibility, which can adapt to different models of sliders, but the disadvantages are low efficiency and quality dependence on the proficiency of operators. Although semi-automatic assembly improves efficiency to a certain extent, manual participation is still required in key steps, full automation cannot be achieved, and the assembly quality still fluctuates.

[0004] The main defect of the existing technology is that the assembly process overly relies on manual labor, resulting in low assembly efficiency of the slider and unstable assembly quality, making it difficult to meet the needs of large-scale production. Summary of the Invention

[0011] By adopting the above technical scheme, the discharge blind hole is used to facilitate the placement of the shock-absorbing block, and the pushing cylinder is used to facilitate the pushing of the installation head toward the plastic block, thereby facilitating the automatic installation of the shock-absorbing block on the plastic block, and helping to minimize the degree of manual participation in the assembly process of the slider for the automobile window lifter, thereby helping to improve the assembly efficiency of the slider for the automobile window lifter, and at the same time helping to improve the consistency of the slider assembly quality.

[0012] In a specific feasible implementation, the assembly mechanism includes a robotic arm, on which an electric screwing device is provided. On the workbench, a spacing adjustment component for adjusting the spacing between two metal sheets is provided, and a positioning component for positioning the working position of the electric screwing device is also provided on the workbench.

[0013] By adopting the above technical solution, the use of the spacing adjustment component helps to adjust the spacing between two metal sheets, thereby helping to improve the accuracy of the relative positions of the two metal sheets during assembly; the use of the positioning component helps to position the working position of the electric screwing device; the use of the positioned electric screwing device helps to automatically assemble the two metal sheets after the spacing adjustment is completed, helps to minimize the manual participation in the assembly process of the slider for the automotive glass lifter, thereby helping to improve the assembly efficiency of the slider for the automotive glass lifter, and at the same time helps to improve the consistency of the slider assembly quality.

[0014] In a specific feasible implementation, the spacing adjustment component includes a first cylinder and a top support gasket. The first cylinder is provided on the workbench and is located on one side of the fixed mounting seat. The piston rod of the first cylinder extends towards the fixed mounting seat. The top support gasket is provided on the piston rod of the first cylinder, and a guiding portion is provided on one side edge of the top support gasket away from the first cylinder.

[0015] By adopting the above technical solution, the use of the first cylinder helps to drive the top support gasket to insert between the two metal sheets, thereby helping to adjust the spacing between the two metal sheets, and further helping to improve the accuracy of the relative positions of the two metal sheets during assembly. The use of the guiding portion helps to guide the top support gasket to insert between the two metal sheets, thereby helping to improve the smoothness of the top support gasket inserting between the two metal sheets.

[0016] In a specific feasible implementation, the positioning component includes a second cylinder and an auxiliary positioning plate. The second cylinder is provided on the workbench and is located on one side of the fixed mounting seat. The piston rod of the second cylinder extends towards the fixed mounting seat. The auxiliary positioning plate is provided on the piston rod of the second cylinder, and an auxiliary positioning hole for the electric screwing device to insert is provided on the auxiliary positioning plate.

[0017] By adopting the above technical solution, the use of the second cylinder helps to drive the auxiliary positioning plate to move above the two metal sheets, thereby helping to make the auxiliary positioning hole located directly above the installation positions of the two metal sheets, and further helping to position the working position of the electric screwing device, and helping to improve the accuracy of the working position of the electric screwing device.

[0018] In a specific feasible implementation, the fixed mounting base is hollow inside. A through hole is provided on the top wall of the fixed mounting base. A connecting spring is provided on the inner top wall of the fixed mounting base around the periphery of the through hole. A connecting disk is provided at the bottom end of the connecting spring. A plurality of telescopic connecting rods are provided on the connecting disk. One end of the telescopic connecting rod away from the connecting disk is connected to the inner top wall of the fixed mounting base. A positioning plug is provided on the connecting disk, and one end of the positioning plug away from the connecting disk penetrates through the through hole. A locking component and a transmission component are provided inside the fixed mounting base. The transmission component is used to cooperate with the locking component to lock and unlock the position of the positioning plug under the action of the movable mounting base.

[0019] By adopting the above technical solution, when the fixed mounting base and the movable mounting base move away from each other, the connecting spring and the telescopic connecting rods help to pull the connecting disk, thereby helping the top end of the positioning plug to extend upward through the through hole. Furthermore, it helps to use the positioning plug to position the placement positions of the two metal sheets, improving the accuracy of the positions where the two metal sheets are placed on the fixed mounting base. When the movable mounting base abuts against the fixed mounting base and the positioning plug moves downward when the two metal sheets are being assembled, the transmission component helps to drive the locking component to lock the position of the positioning plug, thereby helping to prevent the positioning plug from pushing up the assembled two metal sheets under the drive of the connecting spring and the connecting disk. Moreover, it helps to avoid the deformation of the insertion position of the metal sheet and the plastic block caused by the positioning plug pushing up the assembled metal sheet, and helps to ensure the assembly quality of the slider.

[0020] In a specific feasible implementation, the locking component includes a connecting plate, a pawl, a scroll spring, a moving block, and a plurality of ratchet teeth. The connecting plate is vertically arranged on the bottom surface of the connecting disk. The pawl is rotatably arranged on the connecting plate. The scroll spring is sleeved around the rotating shaft of the pawl, and one end of the scroll spring is connected to the connecting plate, and the other end is connected to the pawl. The moving block is movably arranged on the inner bottom wall of the fixed mounting base and is located on one side of the connecting plate. A plurality of the ratchet teeth are arranged at intervals in the vertical direction on the moving block.

[0021] By adopting the above technical solution, the transmission component helps to drive the moving block to move towards the position close to the connecting plate, thereby helping to lock the connecting plate with the ratchet teeth and the pawl when the connecting plate moves downward, and further helping to lock the position of the positioning plug. It helps to prevent the positioning plug from pushing up the assembled two metal sheets under the drive of the connecting spring and the connecting disk, thereby helping to avoid the deformation of the insertion position of the metal sheet and the plastic block caused by the positioning plug pushing up the assembled metal sheet, and further helping to ensure the assembly quality of the slider.

[0022] In a specific feasible implementation, the transmission assembly includes an abutting block, a telescopic rod, a return spring, a first transmission rod, and a second transmission rod. The abutting block is disposed through a side wall of the fixed mounting seat close to the movable mounting seat. One end of the telescopic rod is connected to the abutting block, and the other end is connected to an inner side wall of the fixed mounting seat. The return spring is sleeved around the outer periphery of the telescopic rod. One end of the return spring is connected to the abutting block, and the other end is connected to the inner side wall of the fixed mounting seat. The first transmission rod is hinged to the abutting block. The second transmission rod is rotatably disposed on the inner bottom wall of the fixed mounting seat. The second transmission rod is hinged to an end of the first transmission rod away from the abutting block. An end of the second transmission rod away from the first transmission rod is hinged to the moving block.

[0023] By adopting the above technical solution, when the movable mounting seat gradually abuts against the fixed mounting seat, the movement of the movable mounting seat helps drive the abutting block to move synchronously towards the inside of the fixed mounting seat, thereby helping to drive the moving block to move towards a position close to the connecting plate by the transmission of the first transmission rod and the second transmission rod. Thus, when the connecting plate moves downward, the ratchet teeth cooperate with the ratchet pawl to lock the connecting plate, and further helps to lock the position of the positioning plug rod, helps to block the positioning plug rod from pushing up the assembled two metal sheets under the drive of the connecting spring and the connecting disc, thereby helping to avoid as much as possible the deformation of the insertion position of the metal sheet and the plastic block caused by the positioning plug rod pushing up the assembled metal sheet, and further helps to ensure the assembly quality of the slider.

[0024] In a specific feasible implementation, a positioning block for positioning the placement positions of two metal sheets is disposed on a side wall of the fixed mounting seat. The positioning block is located on a side wall of the fixed mounting seat facing away from the first cylinder, and a proximity switch for detecting whether the two metal sheets are placed is disposed on the positioning block.

[0025] By adopting the above technical solution, the positioning block helps to assist in positioning the placement positions of the two metal sheets, thereby helping to improve the accuracy of the positions of the two metal sheets placed on the fixed mounting seat. The proximity switch helps to detect whether the two metal sheets are placed.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the settings of the driving component, the mounting component, and the assembling mechanism, the driving component helps drive the movable mounting seat to move towards the fixed mounting seat, thereby facilitating the insertion connection between the plastic block and a metal sheet; the mounting component helps automatically mount the damping block onto the plastic block; the assembling mechanism helps assemble two metal sheets; the cooperation of the driving component, the mounting component, and the assembling mechanism helps minimize the manual participation in the assembly process of the slider for the automotive window regulator, thereby helping to improve the assembly efficiency of the slider for the automotive window regulator and also helping to improve the consistency of the slider assembly quality; 2. Through the settings of the transmission component and the locking component, the transmission component helps drive the locking component to lock the position of the positioning plug rod, thereby helping to prevent the positioning plug rod from being driven upward by the connecting spring and the connecting plate to support the two assembled metal sheets, and further helping to avoid the deformation of the insertion position between the metal sheet and the plastic block caused by the positioning plug rod supporting the assembled metal sheet, which helps ensure the assembly quality of the slider.

[0038] Refer to Figure 1 and Figure 3 , when the movable mounting seat 3 stops moving, the pushing cylinder 51 is started, and the piston rod of the pushing cylinder 51 extends, driving the installation head 52 equipped with the damping block to move towards the plastic block, so as to automatically install the damping block on the plastic block, which helps to minimize the degree of manual participation in the assembly process of the slider for the automotive glass lifter, thereby helping to improve the assembly efficiency of the slider for the automotive glass lifter, and at the same time helping to improve the consistency of the slider assembly quality.

[0039] Refer to Figure 1 and Figure 4, an assembly mechanism is provided on the workbench 1. The assembly mechanism includes a robotic arm 6 fixedly installed on the workbench 1, and an electric screwing device 7 is fixedly installed at the end of the robotic arm 6. A spacing adjustment assembly 8 and a positioning assembly 9 are also provided on the workbench 1. The spacing adjustment assembly 8 includes a first cylinder 81 and a top support gasket 82. The first cylinder 81 is fixedly installed on the workbench 1 and is located on one side of the fixed mounting base 2. The piston rod of the first cylinder 81 extends towards the fixed mounting base 2. The top support gasket 82 is fixedly connected to the piston rod of the first cylinder 81, and a guiding portion 821 is integrally formed on one side of the top support gasket 82 away from the first cylinder 81. The positioning assembly 9 includes a second cylinder 91 and an auxiliary positioning plate 92.

The auxiliary positioning plate 92 is fixedly connected to the piston rod of the second cylinder 91, and an auxiliary positioning hole 921 is formed through the auxiliary positioning plate 92.

[0040] Referring to Figure 1 and Figure 4 , start the first cylinder 81. The piston rod of the first cylinder 81 extends, driving the top support gasket 82 to insert between the two metal sheets, thereby adjusting the spacing between the two metal sheets, and further helping to improve the accuracy of the relative positions of the two metal sheets during subsequent assembly. At the same time, start the second cylinder 91. The piston rod of the second cylinder 91 extends, driving the auxiliary positioning plate 92 to move above the two metal sheets, so that the auxiliary positioning hole 921 is located directly above the installation positions of the two metal sheets. Then, the robotic arm 6 drives the electric screwing device 7 to penetrate into the auxiliary positioning hole 921, and the working position of the electric screwing device 7 is positioned through the auxiliary positioning hole 921, which helps to improve the accuracy of the working position of the electric screwing device 7. Start the electric screwing device 7, and automatically assemble the two metal sheets with bolts.

[0041] Referring to Figure 2 and Figure 5 , a locking component 15 is provided inside the fixed mounting base 2. The locking component 15 includes a connecting plate 151, a pawl 152, a scroll spring 153, a moving block 154, and a plurality of ratchet teeth 155. The connecting plate 151 is vertically installed on the bottom surface of the connecting disk 12. The pawl 152 is rotatably installed on the connecting plate 151. The scroll spring 153 is sleeved around the outer periphery of the rotating shaft of the pawl 152, and one end of the scroll spring 153 is fixedly connected to the connecting plate 151, and the other end is fixedly connected to the pawl 152. The moving block 154 is movably placed on the inner bottom wall of the fixed mounting base 2 and is located on one side of the connecting plate 151. The plurality of ratchet teeth 155 are sequentially and spacedly installed on the surface of the moving block 154 facing the connecting plate 151 in the vertical direction.

[0042] Referring to Figure 2 and Figure 5, a transmission assembly 16 is further provided inside the fixed mounting base 2. The transmission assembly 16 includes an abutting block 161, a telescopic rod 162, a return spring 163, a first transmission rod 164 and a second transmission rod 165. The abutting block 161 is installed through the side wall of the fixed mounting base 2 close to the movable mounting base 3. The telescopic rod 162 is horizontally arranged, one end of the telescopic rod 162 is connected to the abutting block 161, and the other end is connected to the inner side wall of the fixed mounting base 2. The return spring 163 is fixedly sleeved on the outer periphery of the telescopic rod 162, one end of the return spring 163 is connected to the abutting block 161, and the other end is connected to the inner side wall of the fixed mounting base 2. The first transmission rod 164 is hinged to the abutting block 161. The second transmission rod 165 is rotatably installed on the inner bottom wall of the fixed mounting base 2. The second transmission rod 165 is hinged to the end of the first transmission rod 164 away from the abutting block 161. The end of the second transmission rod 165 away from the first transmission rod 164 is hinged to the moving block 154.

[0043] Referring to Figure 2 and Figure 5 , when the movable mounting base 3 gradually abuts against the fixed mounting base 2, the movable mounting base 3 gradually abuts against the abutting block 161 and pushes the abutting block 161 to move towards the inside of the fixed mounting base 2. Thus, under the transmission action of the first transmission rod 164 and the second transmission rod 165, the moving block 154 is driven to move towards the position close to the connecting plate 151; during the assembly process of the two metal sheets, the positioning plug 14 moves downward under the pressing action of the bolt, thereby driving the connecting plate 151 and the pawl 152 to move downward. Then, the connecting plate 151 is locked by the cooperation of the ratchet teeth 155 and the pawl 152, which helps to lock the position of the positioning plug 14, helps to block the positioning plug 14 from moving upward under the drive of the connecting spring 11 and the connecting disk 12 to support the assembled two metal sheets, so as to help avoid the deformation of the insertion position of the metal sheet and the plastic block caused by the positioning plug 14 pushing up the assembled metal sheet, and further helps to ensure the assembly quality of the slider.

[0044] The implementation principle of the embodiment of the present application is as follows: When assembling the slider, the operator snaps the plastic block onto the movable mounting base 3 and places the two metal sheets on the fixed mounting base 2 so that the two metal sheets are inserted through the positioning plug 14. After placing, the driving motor 41 is started, and the driving motor 41 drives the lead screw 42 to rotate. Thus, under the cooperation of the limiting plate 43 and the clamping strip 44, the movable mounting base 3 moves towards the fixed mounting base 2 along the length direction of the lead screw 42, and then the plastic block is inserted and fixed with one metal sheet.

[0045] After the movable mounting base 3 stops moving, the pushing cylinder 51 is activated. The piston rod of the pushing cylinder 51 extends, driving the mounting head 52 equipped with a shock-absorbing block to move towards the plastic block, thereby automatically installing the shock-absorbing block onto the plastic block. This helps to minimize the manual participation in the assembly process of the slider for automotive window regulators, thus contributing to improving the assembly efficiency of the slider for automotive window regulators. At the same time, it helps to improve the consistency of the assembly quality of the slider.

[0046] Activate the first cylinder 81. The piston rod of the first cylinder 81 extends, driving the supporting gasket 82 to insert between two metal sheets, thereby adjusting the distance between the two metal sheets, and further contributing to improving the accuracy of the relative positions of the two metal sheets during subsequent assembly. At the same time, activate the second cylinder 91. The piston rod of the second cylinder 91 extends, driving the auxiliary positioning plate 92 to move above the two metal sheets, so that the auxiliary positioning hole 921 is directly above the installation positions of the two metal sheets. Then, the robotic arm 6 drives the electric screwing device 7 to penetrate into the auxiliary positioning hole 921, positioning the working position of the electric screwing device 7 through the auxiliary positioning hole 921, which helps to improve the accuracy of the working position of the electric screwing device 7. Activate the electric screwing device 7 to automatically assemble the two metal sheets with bolts.

[0047] When the movable mounting base 3 gradually abuts against the fixed mounting base 2, the movable mounting base 3 gradually abuts against the abutting block 161 and pushes the abutting block 161 to move towards the inside of the fixed mounting base 2. Thus, driven by the first transmission rod 164 and the second transmission rod 165, the moving block 154 moves towards the position closer to the connecting plate 151. During the assembly process of the two metal sheets, the positioning plug 14 moves downward under the pressing action of the bolt, thereby driving the connecting plate 151 and the pawl 152 to move downward. Then, the connecting plate 151 is locked by the cooperation of the ratchet teeth 155 and the pawl 152, which helps to lock the position of the positioning plug 14 and prevent the positioning plug 14 from pushing upward to support the assembled two metal sheets under the drive of the connecting spring 11 and the connecting disk 12. This helps to avoid deformation of the insertion position of the metal sheet and the plastic block caused by the positioning plug 14 pushing against the assembled metal sheet, and further helps to ensure the assembly quality of the slider.

[0048] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
