Description

Technical Field

[0001] This invention belongs to the field of glass lifter assembly technology, and relates to a glass lifter assembly platform, particularly a single-rail rope wheel type glass lifter assembly platform. Background Technology

[0002] A single-rail rope pulley type window regulator includes a slider, a guide rail, and a steel wire rope. Both ends of the guide rail are rotatably connected to pulleys, one of which is connected to a motor. The slider slides along the guide rail, and the steel wire rope passes over the pulleys and connects to the slider. During use, the steel wire rope must be kept taut. Over time, the steel wire rope will stretch. Currently, a spring is connected to the end of the steel wire rope. Initially, the spring is compressed. When the steel wire rope stretches, the spring keeps the rope taut. This requires the spring to be kept compressed during factory assembly. Currently, single-rail rope pulley type glass lifters are assembled manually by workers. The process involves first applying lubricant to the spring cavity of the slider, then installing the spring-loaded end of the steel wire rope into the spring cavity, and finally securing the wire rope around the pulley. Overcoming the spring force requires significant tension, making the process strenuous. Continuous assembly on the production line puts a heavy strain on workers' hands, impacting production efficiency and their health. Furthermore, manual operation makes it difficult to control the force applied when pulling the wire rope, potentially damaging it. The pulleys are not designed to bear the force of pulling the wire rope, leading to potential damage and reduced lifespan. In the current operation, workers repeatedly handle parts, resulting in a chaotic assembly rhythm and extremely low assembly efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an assembly platform for a single-rail rope wheel type glass lifter. The technical problem solved by this invention is to assist workers in efficiently completing the pre-tightening installation of the wire rope spring.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] An assembly platform for a single-rail rope wheel type glass lifter includes an operating table and a positioning platform fixed on the operating table for positioning the lifter slider. The positioning platform has an operating hole in its center, and a movable platform is located directly below the positioning platform on the operating table. An oiling cylinder and a connecting cylinder are vertically fixed on the movable platform. The movable platform can move horizontally to move either the oiling cylinder or the connecting cylinder to a position aligned with the operating hole. An oil injection seat is fixed to the cylinder rod of the oiling cylinder, and a pin seat for connecting a conformal pin is fixed to the cylinder rod of the connecting cylinder. Tensioning mechanisms for tensioning steel wire ropes are provided on both sides of the positioning platform on the operating table.

[0006] When the moving table is in its initial position, the insertion cylinder is aligned with the operating hole. During assembly, the worker first places the conformal pin on the pin seat. After completion, the moving table moves the insertion cylinder to the operating hole alignment position. The worker places the lifting slider on the positioning table and fixes it. At this time, the oiling cylinder raises the oiling seat, which is then inserted into the spring cavity of the lifting slider to apply oil. After completion, the worker inserts the spring at one end of the wire rope into the spring cavity. The other end of the wire rope is connected to the tensioning mechanism. The tensioning mechanism pulls the wire rope to compress the spring. The other wire rope is tensioned in the same way. After tensioning both wire ropes, the moving table moves the insertion cylinder to the operating hole alignment position. The cylinder raises the pin seat, and the conformal pin on the pin seat inserts into the spring cavity of the lifting slider and is positioned between the two springs, keeping the two springs in a compressed state. After completion, the tensioning mechanism releases the wire rope, realizing the oiling and pre-tightening installation of the spring at the end of the wire rope. The above structure can help workers quickly install the end of the wire rope with the spring onto the slider and can automatically realize the oiling and pre-tightening installation of the spring. Moreover, there is no repetitive workpiece handling during the assembly, the assembly rhythm is smooth, and the assembly efficiency is greatly improved. The pre-tightening of the spring does not require manual operation by the worker, reducing the burden on the worker's hands, ensuring the worker's health, and also improving efficiency.

[0007] In the assembly platform of the single-rail rope wheel type glass lifter described above, the oiling base includes a base and four oiling heads. The base is fixed to the cylinder rod of the oiling cylinder. The four oiling heads are distributed at four corners. Two oiling heads located at the same end form a group. Adjacent oiling heads are mirror images of each other. Each oiling head has a contoured arc surface at its upper end. An oil inlet pipe is provided on the base and is connected to an oil pump. Each oiling head has several vertically arranged oil distribution pipes. The upper end of the oil distribution pipe is located at the contoured arc surface to form an oiling hole one. The lower end of the oil distribution pipe is connected to the oil inlet pipe. The oiling head has several oiling holes two located at the lower edge of the contoured arc surface. The oiling holes two are connected to the middle section of the oil distribution pipes. The oiling holes two on two oiling heads in the same group are staggered relative to each other in the height direction.

[0008] Each oiling head in the same group corresponds to one of the spring cavities of the lifting device slider. The contoured arc surface of the oiling head matches the upper inner wall of the spring cavity. The contoured arc surface is a quarter of a cylindrical surface. During oiling, the oiling seat is raised by the oiling cylinder until the contoured arc surface of the oiling head is aligned with the upper inner wall of the spring cavity. At this time, the distance between the contoured arc surface and the upper inner wall of the spring cavity is 1-2mm. Oiling hole one is directly opposite the upper inner wall of the spring cavity, and oiling hole two is directly opposite the vertical wall of the spring cavity located at the lower edge of the upper inner wall. The lubricating oil is pumped into the oil inlet line by the oil pump, and then the lubricating oil is distributed from the oiling hole through the oil distribution line. The lubricating oil is extruded into the spring cavity through the first and second oiling holes. When the oil is extruded, it spreads outwards. As the oiling seat moves downwards to reset, it spreads the extruded lubricating oil to more areas of the spring cavity, thus achieving the oiling operation of the spring cavity. The different heights of the second oiling holes create a height difference, avoiding pressure dispersion at the same height, which would result in less and uneven oil output from all the second oiling holes. The oil output pressure of the second oiling holes is not dispersed at different heights, ensuring that the oil output pressure of the second oiling holes is sufficient to extrude enough lubricating oil and ensures that the lubricating oil is extruded and applied to the spring cavity relatively evenly.

[0009] In the assembly platform of the aforementioned single-rail cable pulley type window lifter, the diameter of the second oiling hole is smaller than that of the first oiling hole. The first oiling hole can apply more lubricating oil to the upper inner wall of the spring cavity, which has a larger contact surface with the spring, while the second oiling hole can apply relatively less lubricating oil to the vertical wall of the spring cavity, which has a smaller contact surface with the spring, thus maximizing the utilization of lubricating oil.

[0010] In the assembly platform of the aforementioned single-rail rope wheel type window regulator, the upper end of the oiling head is provided with a stop block higher than the inner end of the contoured arc surface, and the oiling head is provided with an upwardly extending flange at the upper edge of the contoured arc surface. When the contoured arc surface of the oiling head is aligned with the upper inner wall of the spring cavity, the stop block and flange can respectively abut against the edge of the spring cavity, preventing the lubricating oil spread out of the spring cavity during oiling, so that the lubricating oil can be fully coated on the inner wall of the spring cavity, improving the oiling effect.

[0011] In the assembly platform of the aforementioned single-rail rope wheel type glass lifter, the tensioning mechanism includes an end positioning block, a tensioning cylinder, a first guide rail, and a tensioning pulley. The first guide rail and the tensioning cylinder are fixed on the side of the positioning platform on the operating table. A slide is provided on the first guide rail. The cylinder rod of the tensioning cylinder is fixedly connected to the slide. The tensioning cylinder can drive the slide to slide away from or towards the operating table along the first guide rail. The tensioning pulley is installed on the upper end of the slide. The end positioning block is fixed on the positioning platform. During operation, after the spring at one end of the wire rope is engaged in the spring cavity, the wire rope passes over the tensioning pulley, positioning the other end of the wire rope on the end positioning block. Then, the tensioning cylinder drives the slide block to move away from the operating table, causing the tensioning pulley to tension the wire rope. At this time, the spring at the end of the wire rope is compressed. After both wire ropes are tensioned, the insertion cylinder inserts the conformal pin into the slide block, completing the pre-tensioning installation of the spring. The tensioning cylinder then resets and releases the wire rope. By setting the extension and retraction amount of the tensioning cylinder, the tension force applied to the wire rope can be controlled, compressing the spring while avoiding damage to the wire rope due to excessive force.

[0012] In another scenario, in the assembly platform of the aforementioned single-rail rope wheel type glass lifter, the tensioning mechanism includes a tensioning cylinder, a first guide rail, and a gripper cylinder. The first guide rail and the tensioning cylinder are fixed on the side of the positioning platform on the operating table. A slide is provided on the first guide rail. The cylinder rod of the tensioning cylinder is fixedly connected to the slide. The tensioning cylinder can drive the slide to slide along the first guide rail away from or towards the operating table. The gripper cylinder is fixed on the slide. During operation, after the spring at one end of the wire rope is inserted into the spring cavity, the wire rope is placed into the gripper of the clamping cylinder. The gripper of the clamping cylinder clamps the wire rope. The tensioning cylinder drives the slide to move away from the operating table, and the clamping cylinder pulls the wire rope, compressing the spring at the end of the wire rope. After both wire ropes are tensioned, the insertion cylinder inserts the conformal pin into the slide, completing the pre-tensioning installation of the spring. The tensioning cylinder then resets and releases the wire rope. By setting the extension and retraction amount of the tensioning cylinder, the tension force applied to the wire rope can be controlled, compressing the spring while avoiding damage to the wire rope due to excessive force.

[0013] In the assembly platform of the aforementioned single-rail cable wheel type glass lifter, a guide rail is fixed on one side of the positioning platform located at the operating hole. The guide rail matches the lifter guide rail. After the spring pre-tensioning of the wire rope is completed, the lifter guide rail is slid along the guide rail toward the lifter slider, thus completing the assembly of the lifter slider and the lifter guide rail, which can further improve the assembly efficiency of the single-rail cable wheel type glass lifter.

[0014] In the assembly platform of the aforementioned single-rail rope wheel type glass lifter, the positioning platform is equipped with at least three rotary lifting cylinders, which are arranged in a triangular pattern. Each rotary lifting cylinder has a horizontal pressure rod on its cylinder rod. After the lifter slider is placed on the positioning platform, the three rotary lifting cylinders rotate and press the pressure rods against the lifter slider, thus fixing the lifter slider on the positioning platform.

[0015] In the assembly platform of the aforementioned single-rail cable pulley type glass lifter, a movable cylinder and two guide rails are fixed to the bottom of the operating platform. The two guide rails are arranged in parallel, and the two sides of the movable platform are slidably connected to the two guide rails. The cylinder rod of the movable cylinder is fixedly connected to one end of the movable platform. Stable movement of the movable platform can be achieved through the two guide rails.

[0016] Compared with existing technologies, the assembly platform of this single-rail rope wheel type glass lifter has the advantages of assisting workers to efficiently complete the pre-tightening installation of the wire rope spring, reducing the burden on workers' hands, ensuring workers' health, and avoiding damage to the wire rope due to excessive force.

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] Example 1

[0033] like Figures 1 to 13As shown, the assembly platform of the single-rail rope wheel type glass lifter includes an operating table 1 and a positioning table 2 fixed on the operating table 1 to position the lifter slider 7. The positioning table 2 has an operating hole 21 in the middle and a mold on the positioning table 2. The mold matches the lifter slider 7 to assist in fixing the lifter slider 7. The positioning table 2 is equipped with three rotary lifting cylinders 22, which are arranged in a triangular pattern. Each rotary lifting cylinder 22 has a horizontal pressure rod 23 on its cylinder rod. The cylinder rod of the rotary lifting cylinder 22 can rotate and move up and down. When in the initial position, the cylinder rod of the rotary lifting cylinder 22 is raised and the pressure rod 23 is rotated to the side away from the mold. When the lifting slider 7 is fixed, the cylinder rod of the rotary lifting cylinder 22 moves downward and rotates, so that the pressure rod 23 is finally pressed against the lifting slider 7. A detection head 24 is fixed to the lower side of the end of one of the pressure rods 23. The detection head 24 of the pressure rod 23 can press against the plastic part of the lifting slider 7. The detection head 24 can detect whether the assembled lifting slider 7 has a plastic part installed. If the plastic part is not installed, the detection head 24 will be inserted into the mounting hole of the plastic part, and the downward stroke of the corresponding rotary lifting cylinder 22 will exceed the set value, and an alarm will be sent to the controller to indicate that the plastic part is not installed.

[0034] A guide rail 25 is fixed on one side of the positioning platform 2, located at the operating hole 21. The guide rail 25 matches the lifting guide rail 71. After the spring 73 of the wire rope 72 is pre-tightened, the lifting guide rail 71 is slid along the guide rail 25 toward the lifting slider 7, thus completing the assembly of the lifting slider 7 and the lifting guide rail 71.

[0035] A movable platform 3 is located directly below the positioning platform 2 on the operating table 1. A movable cylinder 31 and two guide rails 32 are fixed at the bottom of the operating table 1. The two guide rails 32 are arranged in parallel. The two sides of the movable platform 3 are slidably connected to the two guide rails 32 respectively. The cylinder rod of the movable cylinder 31 is fixedly connected to one end of the movable platform 3. The movable platform 3 is located directly below the positioning platform 2. The movable cylinder 31 can drive the movable platform 3 to move horizontally back and forth.

[0036] An oiling cylinder 4 and a plug-in cylinder 5 are vertically fixed on the moving table 3. The moving table 3 can move the oiling cylinder 4 or the plug-in cylinder 5 to a position aligned with the operating hole 21 by moving horizontally back and forth. An oil filling seat 41 is fixed on the cylinder rod of the oiling cylinder 4, and a pin seat 51 that can connect to the contour pin 74 is fixed on the cylinder rod of the plug-in cylinder 5.

[0037] like Figure 10 and Figure 11As shown, the oiling seat 41 includes a base 42 and four oiling heads 43. The base 42 is fixed to the cylinder rod of the oiling cylinder 4. The four oiling heads 43 are distributed at four corners, and a cross groove is formed between the four oiling heads 43 to match the cross structure between the two spring 73 cavities of the lifting slider 7. Two oiling heads 43 located at the same end form a group, and adjacent oiling heads 43 are arranged in mirror image. Each oiling head 43 has a contoured arc surface 44 at its upper end. The upper end of the oiling head 43 has a stop 45 that is higher than the contoured arc surface 44 on the inner side of the contoured arc surface 44. The oiling head 43 has an upwardly extending part on the upper edge of the contoured arc surface 44. The base 42 has an oil inlet pipe 421 connected to an oil pump. Each oiling head 43 has several vertically arranged oil distribution pipes 47. The upper end of the oil distribution pipe 47 is located at the contoured arc surface 44 to form an oiling hole 48. The lower end of the oil distribution pipe 47 is connected to the oil inlet pipe 421. The oiling head 43 has several oiling holes 49 located at the lower edge of the contoured arc surface 44. The diameter of the oiling hole 49 is smaller than the diameter of the oiling hole 48. The oiling hole 49 is connected to the middle section of the oil distribution pipe 47. The oiling holes 49 on two oiling heads 43 in the same group are staggered in the height direction. The oiling head 43 in the same group corresponds to one of the spring 73 cavities of the lifting slider 7. The contoured arc surface 44 on the oiling head 43 matches the upper inner wall of the spring 73 cavity. The contoured arc surface 44 is a quarter-cylindrical surface. During oiling, the oiling seat 41 is raised by the oiling cylinder 4 to the position where the contoured arc surface 44 of the oiling head 43 is aligned with the upper inner wall of the spring 73 cavity. At this time, the distance between the contoured arc surface 44 and the upper inner wall of the spring 73 cavity is 1-2mm. The oiling hole 48 and the spring 73 are aligned. The upper inner wall of the cavity is directly opposite to the vertical wall at the lower edge of the upper inner wall of the spring 73 cavity. The lubricating oil is pumped into the oil inlet pipe 421 by the oil pump, and then the lubricating oil is squeezed out from the oil inlet 48 and the oil inlet 49 through the oil distribution pipe 47 and applied to the spring 73 cavity. When the lubricating oil is squeezed out, it will spread outwards. When the oil injection seat 41 moves downwards to reset, it will apply the squeezed lubricating oil to more positions in the spring 73 cavity, thereby achieving the oiling operation of the spring 73 cavity.

[0038] like Figure 9 and Figure 12 As shown, tensioning mechanisms 6 for tensioning steel wire rope 72 are provided on both sides of the positioning platform 2 on the operating table 1. The tensioning mechanism 6 includes an end positioning block 65, a tensioning cylinder 61, a guide rail 62, and a tensioning pulley 63. The guide rail 62 and the tensioning cylinder 61 are fixed on the side of the positioning platform 2 on the operating table 1. A slide 64 is provided on the guide rail 62. The cylinder rod of the tensioning cylinder 61 is fixedly connected to the slide 64. The tensioning cylinder 61 can drive the slide 64 to slide away from or towards the operating table 1 along the guide rail 62. The tensioning pulley 63 is installed on the upper end of the slide 64. The end positioning block 65 is fixed on the positioning platform 2.

[0039] When the moving platform 3 is in its initial position, the insertion cylinder 5 is aligned with the operating hole 21. During assembly, the worker first places the conformal pin 74 on the pin seat 51. After completion, the moving platform 3 moves to move the insertion cylinder 5 to the alignment position of the operating hole 21. The worker places the lifting slider 7 on the positioning platform 2 and fixes it. At this time, the oiling cylinder 4 raises the oiling seat 41, and the oiling seat 41 is inserted into the spring 73 cavity of the lifting slider 7 to apply oil. After completion, the worker inserts the spring 73 at one end of the wire rope 72 into the spring 73 cavity. The other end of the wire rope 72 passes around the tension pulley 63 and is positioned on the end positioning block 65. The tension pulley 63 moves to pull the wire rope 72. 2. Compress spring 73, and perform the same operation on the other wire rope 72. After tensioning both wire ropes 72, the moving platform 3 moves the insertion cylinder 5 to the operating hole 21 for alignment. The insertion cylinder 5 raises the pin seat 51, and the conformal pin 74 on the pin seat 51 is inserted into the spring 73 cavity of the lifting slider 7 and positioned between the two springs 73, so that the two springs 73 remain compressed. After completion, the tensioning cylinder 61 resets and releases the wire rope 72, realizing the oiling and pre-tightening installation of the spring 73 at the end of the wire rope 72. In this embodiment, the extension and retraction stroke of each cylinder is preset according to the different models of single guide rail rope wheel type glass lifters.

[0040] Example 2

[0041] This embodiment is basically the same as the first embodiment in terms of structure and principle. The difference is that the tensioning mechanism includes a tensioning cylinder, a guide rail, and a gripper cylinder. The guide rail and the tensioning cylinder are fixed on the side of the positioning table on the operating table. A slide is provided on the guide rail. The cylinder rod of the tensioning cylinder is fixedly connected to the slide. The tensioning cylinder can drive the slide to slide away from or towards the operating table along the guide rail. The gripper cylinder is fixed on the slide. During operation, after the spring at one end of the wire rope is inserted into the spring cavity, the wire rope is placed into the gripper of the clamping cylinder. The gripper of the clamping cylinder clamps the wire rope. The tensioning cylinder drives the slide to move away from the operating table, and the clamping cylinder pulls the wire rope, compressing the spring at the end of the wire rope. After both wire ropes are tensioned, the insertion cylinder inserts the conformal pin into the slide, completing the pre-tensioning installation of the spring. The tensioning cylinder then resets and releases the wire rope. By setting the extension and retraction amount of the tensioning cylinder, the tension force applied to the wire rope can be controlled, compressing the spring while avoiding damage to the wire rope due to excessive force.
