Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing equipment technology, and in particular to an integrated assembly and testing device for a knob rotor. Background Technology

[0002] Currently, the rear wiper knob and front wiper knob assembly of the combination switch are still mainly assembled manually. First, lubricant is applied to the assembly cavity of the workpiece, then the spring is installed inside the cavity, and finally the steel ball is placed at the end of the spring, completing the lubrication and assembly of the spring and steel ball. However, manual assembly is not only costly and inefficient, but it also easily leads to the omission of springs or steel balls, affecting product quality. Furthermore, the knob assembly, once installed on the rear of the vehicle, interferes with the operation of both the rear and front wipers. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides an integrated assembly and testing device for knob rotors, which automates assembly, achieves precise assembly and automatic oiling of springs and steel balls, and also performs testing to avoid omissions. This not only improves assembly efficiency and quality but also reduces labor costs.

[0004] The technical solution of this invention: An integrated assembly and testing device for a knob rotor, comprising a frame, wherein the frame is provided with a workpiece loading station, an oiling station, a spring and ball bearing loading station, a pressing station, and a testing station. The workpiece loading station is provided with a workpiece support and a first driving component that drives the workpiece support to slide sequentially to the oiling station, the assembly station, and the testing station. The oiling station is provided with an oiling gun and a second driving component that drives the oiling gun to move up and down. The spring and ball bearing loading station is provided with a spring loading device and a ball bearing loading device, which are mounted on a first mounting frame. The device is also equipped with a third driving component for rotating the first mounting frame and a fourth driving component for axially sliding the first mounting frame. The spring feeding device includes a positioning column, a fifth driving component for lifting the positioning column, two grippers, and a sixth driving component for moving the two grippers toward each other or away from each other. The sidewalls of the two grippers opposite each other are provided with arc-shaped grooves adapted to the positioning column. The ball feeding device includes a suction cup and a seventh driving component for lifting the suction cup. The seventh driving component is located on the first mounting frame. The pressing station is equipped with a pressing component and an eighth driving component for lifting the pressing component. The detection station is equipped with a detection component and a ninth driving component for lifting the detection component.

[0005] Using the above technical solution, the workpiece requiring springs and balls is placed in the workpiece carrier. Then, the first drive unit conveys the workpiece carrier towards the oiling station, where lubricating oil is applied using an oiling gun. After application, the carrier continues to be conveyed to the spring and ball loading station, where the springs and balls are installed sequentially. Then, the pressing component presses the springs and balls into the assembly cavity of the workpiece. The first drive unit drives the workpiece carrier towards the inspection station, where an inspection component checks whether springs and balls are installed in the assembly cavity to prevent omissions. After inspection, the carrier is conveyed to the workpiece loading station, where the assembled workpiece is removed and a new workpiece is installed. This automated assembly method achieves precise assembly and automatic oiling of springs and balls, and also performs quality inspection to prevent omissions. This improves assembly efficiency and quality while reducing labor costs.

[0006] A further feature of the present invention is that the first mounting frame is also provided with a spring pickup device, the spring pickup device including a fixed frame, a tenth driving member for driving the fixed frame to rise and fall, two pickup claws provided on the fixed frame, and an eleventh driving member for driving the two pickup claws to move towards each other or away from each other. The tenth driving member is provided on the first mounting frame, and the output end of the tenth driving member is connected to the fixed frame. The eleventh driving member is provided on the fixed frame and is provided with two connecting posts connected to the pickup claws.

[0007] Further configuration: The spring and ball loading station is also equipped with a spring flipping device. The spring flipping device includes a second mounting frame, a flipping frame, and a twelfth driving member for flipping the flipping frame. The flipping frame is provided with a receiving groove for accommodating the spring. The two ends of the flipping frame are mounted on the second mounting frame through a rotating shaft, and flipped relative to the second mounting frame under the action of the twelfth driving member to change the spring from a horizontal state to a vertical state.

[0008] With the above-mentioned further configuration, after the picking claw picks up the spring, it drives the first mounting bracket to rotate via the third driving component. The rotation is directed to the spring flipping device, which places the spring into the receiving slot. At this time, the spring is in a horizontal state. The twelfth driving component drives the flipping bracket to rotate 90°, so that the spring is in a vertical state. Then, the positioning pin is inserted into the spring, and the two grippers move towards each other to clamp the spring, remove the spring from the receiving slot, and clamp it onto the workpiece. This realizes the spring loading, ensuring that each spring is vertically installed on the workpiece, avoiding the situation where the spring cannot be installed when it is horizontal.

[0009] The invention is further configured such that: the flipping frame is provided with a pressing block and a thirteenth driving member for driving the pressing block to rise and fall; both the pressing block and the flipping frame are provided with semi-circular grooves adapted to the spring; when the pressing block contacts the flipping frame under the action of the thirteenth driving member, the two semi-circular grooves form the receiving groove; the second mounting frame is also provided with a limiting block; the limiting block is located at the inlet of the receiving groove, and the upper end face of the limiting block is at the same height as the inlet of the receiving groove.

[0010] With the above-mentioned further configuration, after the spring is horizontally installed into the semi-circular groove of the tilting frame, the pressing block moves down under the action of the thirteenth driving component and presses onto the tilting frame to position the spring. This prevents the spring from falling off when the tilting frame is tilted, thus affecting the spring loading. The limiting block can limit the picking claw. During the downward movement of the picking claw, the picking claw contacts the limiting block and stops moving down. At this time, the spring is just aligned with the receiving groove, avoiding misalignment between the spring and the receiving groove, which would prevent it from being installed.

[0011] A further embodiment of the present invention includes: a third mounting bracket and a fourteenth driving member on the workpiece loading station; the workpiece bearing seat is connected to the output shaft of the fourteenth driving member and rotates horizontally relative to the third mounting bracket under the action of the fourteenth driving member; the workpiece bearing seat is provided with a workpiece seat plate, pressure feet located on both sides of the workpiece seat plate, and a fifteenth driving member that drives the pressure feet to swing; the workpiece seat plate is provided with a receiving cavity for accommodating the workpiece; the bottom of the workpiece seat plate is provided with a spring mounting channel; and the two pressure feet can press onto the workpiece to prevent the workpiece from falling out of the receiving cavity when the workpiece bearing seat rotates.

[0012] With the above-mentioned further configuration, after the workpiece is placed into the receiving cavity, the two pressure feet swing and press on the workpiece. The fourteenth driving component drives the workpiece bearing seat to rotate 180 degrees, so that the spring mounting channel on the workpiece seat plate faces upward. After the spring and ball are installed into the spring mounting channel, the spring and ball are pressed into the assembly cavity of the workpiece by the pressing component. Pre-installation is performed by the workpiece seat plate, and the installation positioning is more accurate.

[0013] A further provision of the present invention: the frame is provided with a fourth mounting bracket, which is located between the workpiece loading station and the spring and ball loading station, and the second driving member, the eighth driving member and the ninth driving member are all mounted on the fourth mounting bracket.

[0014] The above-mentioned further design results in a compact structure that does not hinder the operation of each device.

[0015] A further feature of the present invention is that the workpiece loading station is also equipped with a sensor for detecting whether a workpiece is mounted on the workpiece carrier.

[0016] By adopting the above-mentioned further settings, it is possible to detect whether a workpiece is loaded on the workpiece carrier. Only after the workpiece is loaded will the first drive component start working, thus avoiding wasted effort.

[0017] A further embodiment of the present invention includes: the spring feeding device includes a feeding plate and a vibrating plate, the discharge port of the feeding plate is provided corresponding to the vibrating plate, and a vision sensor is also provided on the frame, the vision sensor being located above the vibrating plate.

[0018] With the above-mentioned further settings, all the springs inside the vibratory feeder are in a horizontal state, making them easy to grip, and the vision sensor can detect the condition of the springs inside the vibratory feeder in real time.

[0019] A further feature of the present invention is that the frame is provided with an outer cover, the outer cover has an opening corresponding to the workpiece loading station for loading and unloading workpieces, and the outer cover is provided with a control panel.

[0020] By adopting the above-mentioned further settings, each device is protected to avoid exposure, and the values ​​of each driving component can be set on the control panel. The setting of the opening does not affect the loading and unloading of workpieces. Attached Figure Description

The opposing side walls of the two grippers 413 are provided with arc-shaped grooves 4131 adapted to the positioning post 411. The ball feeding device 42 includes a suction cup 421 and a seventh driving member 422 for driving the suction cup 421 to rise and fall. The seventh driving component 422 is mounted on the first mounting bracket 43. The pressing station 5 is equipped with a pressing component 51 and an eighth driving component 52 that drives the pressing component 51 to move up and down. The pressing component 51 is cylindrical. The detection station 6 is equipped with a detection component 61 and a ninth driving component 62 that drives the detection component 61 to move up and down. The detection component 61 is a metal detector. The workpieces that need to be installed with springs and balls are placed in the workpiece carrier 21. Then, the first driving component 22 conveys the workpiece carrier 21 towards the oiling station 3. Lubricating oil is applied by the oiling gun 31. After the oiling is completed, the workpieces are conveyed to the spring and ball loading station 4 for sequential loading of springs and balls. The assembly process involves installing the spring and ball bearings, then pressing them into the workpiece's assembly cavity using the pressing component 51. The first driving component 22 drives the workpiece carrier 21 towards the inspection station 6. The inspection component 61 checks whether the spring and ball bearings are installed in the assembly cavity to prevent omissions. After inspection, the assembly is conveyed to the workpiece loading station 2, where the assembled workpiece is removed and a new workpiece is installed. This automated assembly method achieves precise assembly and automatic oiling of the spring and ball bearings, and also performs quality inspection to prevent omissions. This improves assembly efficiency and quality while reducing labor costs. The driving components can be pneumatic cylinders, motors, or electric cylinders. The ball bearing loading device 42 also includes a ball bearing loading track, a rotating disk 423, and a sixteenth driving component that drives the rotating disk. The rotating disk 423 has several slots 424 for accommodating ball bearings, loading them one by one and positioning them for easy suction cup adsorption.

[0028] The first mounting frame 43 is also equipped with a spring picking device 46. The spring picking device 46 includes a fixed frame 461, a tenth driving member for driving the fixed frame 461 to rise and fall, two picking claws 463 on the fixed frame 461, and an eleventh driving member 464 for driving the two picking claws 463 to move towards each other or away from each other. The tenth driving member is mounted on the first mounting frame 43, and its output end is connected to the fixed frame 461. The eleventh driving member 464 is mounted on the fixed frame 461 and is equipped with two connecting posts 465 connected to the picking claws 463. The fixed frame 461 is also equipped with a positioning member 466, and the positioning member 466 is equipped with a positioning plate 467. The positioning plate 467 is located between the two picking claws 463. After the two picking claws 463 pick up the spring, the positioning plate 467 is located on the upper end face of the spring. The spring and ball loading station 4 is also equipped with a spring flipping device 47, which includes a second mounting frame 471. The rotating frame 472 and the twelfth driving member 473 drive the rotating frame 472 to rotate. The rotating frame 472 is provided with a receiving groove for accommodating springs. The two ends of the rotating frame 472 are mounted on the second mounting frame 471 through a rotating shaft. Under the action of the twelfth driving member 473, the rotating frame 472 rotates relative to the second mounting frame 471 to change the spring from a horizontal state to a vertical state. After the picking claw 463 picks up the spring, the first mounting frame 43 is driven to rotate by the third driving member 44. The rotation is to the spring rotating device 47, and the spring is placed into the receiving groove. At this time, the spring is in a horizontal state. The twelfth driving member 473 drives the rotating frame 472 to rotate 90° so that the spring is in a vertical state. Then the positioning pin 411 is inserted into the spring, and the two grippers 413 move towards each other to clamp the spring, take the spring out of the receiving groove, and clamp it onto the workpiece to realize the spring loading. This ensures that each spring is vertically installed on the workpiece, avoiding the situation where the spring cannot be installed when it is horizontal.

[0029] The tilting frame 472 is provided with a pressing block 474 and a thirteenth driving member 475 for driving the pressing block 474 to rise and fall. Both the pressing block 474 and the tilting frame 472 are provided with semi-circular grooves 476 adapted to the spring. When the pressing block 474 contacts the tilting frame 472 under the action of the thirteenth driving member 475, the two semi-circular grooves 476 form the receiving groove. The second mounting frame 471 is also provided with a limiting block 477. The limiting block 477 is located at the inlet of the receiving groove, and the upper end face of the limiting block 477 is at the same level as the inlet of the receiving groove. After the spring is horizontally installed into the semi-circular groove 476 of the tilting frame 472, the pressing block 474 moves down under the action of the thirteenth driving member 475 and presses onto the tilting frame 472 to position the spring, so that the spring will not fall off when the tilting frame 472 is tilted, thus affecting the spring loading. The limiting block 477 can limit the picking claw 463. During the downward movement of the picking claw 463, the picking claw 463 contacts the limiting block 477 and stops moving down. At this time, the spring is just aligned with the receiving groove, avoiding misalignment between the spring and the receiving groove, which would prevent it from being installed.

[0030] The frame 1 is provided with a fourth mounting bracket 11, which is located between the workpiece loading station 2 and the spring and ball loading station 4. The second driving component 32, the eighth driving component 52 and the ninth driving component 62 are all mounted on the fourth mounting bracket 11. The structure is compact and does not hinder the operation of each device. The spring loading device 41 also includes a loading plate 415 and a vibrating plate 416. The discharge port of the loading plate 415 is set corresponding to the vibrating plate 416. The frame 1 is also provided with a vision sensor 12, which is located above the vibrating plate 416, so that the springs in the vibrating plate 416 are all in a horizontal state, which is convenient for clamping. The vision sensor 12 can detect the condition of the springs in the vibrating plate 416 in real time.

[0031] The workpiece loading station 2 is equipped with a third mounting bracket 23 and a fourteenth driving member 24. The workpiece bearing seat 21 is connected to the output shaft of the fourteenth driving member 24 and rotates horizontally relative to the third mounting bracket 23 under the action of the fourteenth driving member 24. The workpiece bearing seat 21 is equipped with a workpiece seat plate 25, pressure feet 26 located on both sides of the workpiece seat plate 25, and a fifteenth driving member 27 that drives the pressure feet 26 to swing. The workpiece seat plate 25 is equipped with a receiving cavity for accommodating the workpiece. The bottom of the workpiece seat plate 25 is equipped with a spring mounting channel 251. The two pressure feet 26 can press on the workpiece to prevent the workpiece from falling out of the receiving cavity when the workpiece bearing seat 21 is rotated. After the workpiece is placed in the receiving cavity, the two pressure feet 26 swing and press on the workpiece. The fourteenth driving member 24 drives the workpiece bearing seat 21 to rotate 180 degrees, so that the spring mounting channel on the workpiece seat plate 25... With channel 251 facing upwards, after the spring and ball bearings are installed into the spring mounting channel 251, the spring and ball bearings are pressed into the assembly cavity of the workpiece by the pressing component 51. Pre-installation is performed by the workpiece seat plate 25, making the installation and positioning more accurate. The workpiece loading station 2 is also equipped with a sensor 28 to detect whether a workpiece is assembled on the workpiece carrier 21. It can detect whether a workpiece is loaded on the workpiece carrier 21. After the workpiece is loaded, the first drive component 22 will start working to avoid wasting work. Multiple workpiece carriers 21 can be set and arranged side by side, so that multiple workpieces can be assembled at the same time. There are also multiple corresponding pressing components 51 and detection components 61. The oiling gun 31 slides laterally on the fourth mounting frame 11 to apply lubricating oil to the workpieces in each row. The frame 1 is equipped with a guide rail, and the workpiece carrier 21 slides on the guide rail, which has good stability.

[0032] The frame 1 is provided with an outer cover 13, and the outer cover 13 has an opening corresponding to the workpiece loading station 2 for loading and unloading workpieces.
