[0001] The invention belongs to the technical field of skylight bracket processing, and in particular relates to a skylight bracket cleaning method. Background Art

[0002] The car sunroof can not only effectively circulate air in the car, but also increase the entry of fresh air, bringing healthy and comfortable enjoyment to the car owner.

[0003] The sunroof bracket is an important part of the car sunroof. After processing, the sunroof bracket will be attached with impurities such as oil, metal debris, etc. before the next process. The sunroof bracket needs to be cleaned. Usually, an ultrasonic cleaning device is used to clean the sunroof bracket. The sunroof brackets are stacked in the cleaning box, and the sunroof brackets are easily squeezed and damaged. The ultrasonic cleaning method can only loosen the impurities on the surface of the sunroof bracket but it is difficult to make them fall off. The cleaning effect is not ideal, and manual brushing is required, which is laborious and inconvenient, and the work efficiency is low. Summary of the invention

[0009] ② Put the clamping hole of one half frame into the fixing protrusion of the other half frame, and clamp the end of the mounting rod through the clamping groove inside the half frame, so that the two half frames are connected to form a complete frame, and the mounting rod is limited between the two half frames, and the cleaning rack is assembled;

[0010] (b) Install the sunroof bracket into the cleaning box of the cleaning device: Use the sleeve hole at the bottom of the L-shaped base on the side of the half frame to cover the guide rod on the side of the cleaning box, so that the cleaning rack is limited between the two guide rods, and the sunroof bracket is located in the cleaning box;

[0011] (c) Cleaning:

[0012] ① Start the liquid pump, which pumps the cleaning liquid in the storage tank into the inner cavity of the cleaning box. The cleaning liquid is sprayed out through the nozzle on the inner wall of the cleaning box to wash the sunroof bracket;

[0013] The driving mechanism is started, and the driving mechanism drives the cam to rotate. The cam intermittently pushes the transmission wheel at the bottom of the guide rod upward, so that the guide rod reciprocates up and down, and the guide rod drives the cleaning rack to reciprocate up and down, so that the sunroof bracket continuously stirs the cleaning liquid in the cleaning box;

[0014] ②When the liquid level in the cleaning tank reaches the liquid level warning line, turn off the liquid pump, and after 10-15 minutes, open the drain port at the bottom of the cleaning tank to drain the cleaning liquid;

[0015] (d) Take out the sunroof brackets: After the sunroof brackets are drained, turn off the drive mechanism, remove the cleaning rack, and then remove the sunroof brackets to prepare for the next batch of sunroof brackets to be cleaned.

[0016] Furthermore, the specific method of ① in step (a) is: pull the lower L-shaped block outward to force the spring between the lower L-shaped block and the upper L-shaped block to be stretched, and the distance between the lower L-shaped block and the upper L-shaped block becomes larger, and then put the frame of the sunroof bracket between the lower L-shaped block and the upper L-shaped block, relax the lower L-shaped block, and pull the lower L-shaped block back with the spring, so that the lower L-shaped block cooperates with the upper L-shaped block to clamp the frame of the sunroof bracket. The sunroof bracket cannot freely detach from the clamp and is clamped and fixed. The fixation is reliable, the operation is simple, and the difficulty is low.

[0017] The clamp includes an upper L-shaped block, a lower L-shaped block, a telescopic rod and a spring. The telescopic rod and the spring are arranged between the upper L-shaped block and the lower L-shaped block. The spring is located in the telescopic rod. The upper L-shaped block is connected to the mounting rod. The clamp has a flexible and variable clamping size and can be applied to skylight brackets of different specifications, with strong applicability.

[0018] Furthermore, a limiting groove corresponding to the sunroof bracket is provided on the lower L-shaped block, which can limit the free movement of the sunroof bracket forward and backward, improve the stability of the sunroof bracket after clamping, and prevent the sunroof bracket from tilting and gradually falling off the clamp after displacement.

[0019] Furthermore, the cleaning device in step (b) includes a support frame, a cleaning box, a liquid storage tank and a liquid pump, the cleaning box is arranged on the support frame, the liquid pump connects the liquid storage tank and the inner cavity of the cleaning box, and a nozzle connected to the inner cavity is provided on the inner wall of the cleaning box; both sides of the cleaning box are connected to guide rods that slide up and down, the bottom of the guide rods is connected to a transmission wheel, a driving mechanism is provided on the support frame, a cam is connected to the driving mechanism, and the cam is in conflict with the transmission wheel.

[0020] Furthermore, a limiting groove is provided on the outer peripheral wall of the cam, and the transmission wheel is located in the limiting groove, so as to ensure that the transmission wheel and the cam are in full contact without misalignment, thereby improving the reliability of the transmission.

[0021] Furthermore, the driving mechanism includes a servo motor and a transmission shaft, the output end of the servo motor is connected to the transmission shaft, the cam is arranged on the transmission shaft, the support frame is provided with a support seat, and the transmission shaft passes through the support seat. The servo motor drives the transmission shaft to rotate, thereby driving the cam to rotate, and the support seat can limit the radial shaking of the transmission shaft, thereby improving the stability of the movement of the transmission shaft.

[0022] Furthermore, a fence is provided on the top of the cleaning box, which increases the fence height of the cleaning box and prevents the cleaning liquid from splashing outwards and polluting the working environment.

[0023] Furthermore, a guide seat is provided on the side of the cleaning box, and the guide seat is slidably connected to the guide rod. The guide seat can limit the radial shaking of the guide rod, thereby improving the movement stability of the guide rod.

[0024] Furthermore, in step (a), the cleaning rack includes two half frames and a mounting rod, the inner side of the half frame is evenly distributed with card grooves corresponding to the mounting rod, one end of the half frame is provided with a fixing protrusion, the other end of the half frame is provided with a card hole corresponding to the fixing protrusion, and a clamp is provided on the mounting rod; an L-shaped base is provided on the half frame, and a sleeve hole corresponding to the guide rod is provided at the bottom of the L-shaped base.

[0025] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0026] 1. The cleaning rack can be disassembled, which is easy to operate and can be used anytime after installation. Damaged parts can be replaced separately, replacing the bolt connection method, which is labor-saving and convenient. When the cleaning rack is installed on the guide rod, the distance between the two guide rods is fixed, which in turn limits the distance between the two half frames. The two half frames cannot be freely disengaged, and the mounting rod is clamped by the two half frames and cannot be freely disengaged. It is restrained step by step, which improves the assembly stability of the cleaning rack and fixes it in one step, replacing the bolt connection method, which is labor-saving and convenient.

[0027] 2. Each skylight bracket is hung independently in the cleaning box without contacting each other to avoid collision and damage. In the initial flushing stage, the liquid level in the cleaning box is low, and the cleaning liquid forms a strong jet flow to flush the skylight bracket with a strong impact. The skylight bracket moving up and down constantly collides with the cleaning liquid. The collision effect is more conducive to the cleaning liquid to wash away impurities such as oil, metal debris attached to the surface of the skylight bracket; in the later flushing stage, the liquid level in the cleaning box is high, and the skylight bracket moving up and down constantly stirs the cleaning liquid, which improves the fluidity of the cleaning liquid, facilitates the cleaning liquid to fully contact with each skylight bracket, and improves the impurity removal effect; in the drainage stage, the skylight bracket moving up and down constantly shakes off the cleaning liquid on the surface, which improves the drainage efficiency. There is no need for additional drying equipment, which reduces equipment costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] like Figures 1 to 6 As shown, the cleaning device used in the present invention includes a support frame 1, a cleaning box 2, a liquid storage tank 3, a liquid pump 4 and a waste liquid tank 5. The cleaning box 2 is arranged on the support frame 1, and the liquid pump 4 connects the liquid storage tank 3 and the inner cavity of the cleaning box 2 through a pipeline. A nozzle 6 connected to the inner cavity is provided on the inner wall of the cleaning box 2, and the waste liquid tank 5 is connected to the discharge port of the cleaning box 2 through a pipeline.

[0037] A baffle 7 is provided on the top of the cleaning box 2 to increase the blocking height of the cleaning box 2 and prevent the cleaning liquid from splashing outwards and polluting the working environment.

[0038] Guide seats 8 are provided on both sides of the cleaning box 2, and guide rods 9 are slidably connected to the guide seats 8. The guide seats 8 can limit the radial shaking of the guide rods 9, thereby improving the movement stability of the guide rods 9.

[0039] A transmission wheel 10 is connected to the bottom of the guide rod 9, and a driving mechanism is provided on the support frame 1. The driving mechanism includes a servo motor 11 and a transmission shaft 12. The servo motor 11 is fixed on the support frame 1, and the output end of the servo motor 11 is connected to the transmission shaft 12. A cam 13 is provided on the transmission shaft 12. The cam 13 conflicts with the transmission wheel 10. The servo motor 11 drives the transmission shaft 12 to rotate, and then drives the cam 13 to rotate, so that the cam 13 intermittently pushes the transmission wheel 10 upward, thereby driving the guide rod 9 to reciprocate up and down.

[0040] A limiting groove 14 is provided on the outer peripheral wall of the cam 13, and the transmission wheel 10 is located in the limiting groove 14, ensuring that the transmission wheel 10 is in full contact with the cam 13 without misalignment, thereby improving the reliability of transmission.

[0041] A support seat 15 is provided on the support frame 1 , and the transmission shaft 12 passes through the support seat 15 . The support seat 15 can limit the radial shaking of the transmission shaft 12 , thereby improving the stability of the movement of the transmission shaft 12 .

[0042] The cleaning method of the skylight bracket comprises the following steps:

[0043] (a) Clamping the sunroof bracket 16: The cleaning rack 17 includes two half frames 18 and a mounting rod 19. The inner side of the half frame 18 is evenly distributed with slots 20 corresponding to the mounting rod 19. One end of the half frame 18 is provided with a fixing protrusion 21, and the other end of the half frame 18 is provided with a fixing hole 22 corresponding to the fixing protrusion 21. The cleaning rack 17 can be disassembled, and the operation is simple. It can be installed and used at any time. The damaged parts can be replaced separately, instead of the bolt connection method, which is labor-saving and convenient.

[0044] An L-shaped base 23 is provided on the half frame 18 , and a sleeve hole 24 corresponding to the guide rod 9 is provided at the bottom of the L-shaped base 23 .

[0045] A clamp 25 is provided on the mounting rod 19, and the clamp 25 includes an upper L-shaped block 26, a lower L-shaped block 27, a telescopic rod 28 and a spring. A fixing rod 29 is provided between the upper L-shaped block 26 and the mounting rod 19, and the telescopic rod 28 and the spring are provided between the upper L-shaped block 26 and the lower L-shaped block 27. The spring is located in the telescopic rod 28, which protects the spring and prevents the spring from being corroded too quickly due to direct contact with the cleaning fluid. By pulling the lower L-shaped block 27 outward, the size of the clamp 25 can be flexibly changed to be suitable for sunroof brackets 16 of different specifications, and the applicability is strong.

[0046] The lower L-shaped block 27 is provided with a limiting groove 30 corresponding to the sunroof bracket 16, which can limit the free movement of the sunroof bracket 16 forward and backward, improve the stability of the sunroof bracket 16 after clamping, and prevent the sunroof bracket 16 from tilting after displacement and gradually detaching from the clamp 25.

[0047] ① Clamp the sunroof bracket 16 on the clamp 25 below the mounting rod 19. The specific method is: pull the lower L-shaped block 27 outward to force the spring between the lower L-shaped block 27 and the upper L-shaped block 26 to be stretched, and the distance between the lower L-shaped block 27 and the upper L-shaped block 26 becomes larger. Then put the frame of the sunroof bracket 16 between the lower L-shaped block 27 and the upper L-shaped block 26, relax the lower L-shaped block 27, and the spring generates a rebound force to pull back the lower L-shaped block 27, so that the lower L-shaped block 27 cooperates with the upper L-shaped block 26 to clamp the frame of the sunroof bracket 16, and the inner side of the frame of the sunroof bracket 16 is embedded in the limiting groove 30. The sunroof bracket 16 cannot freely escape from the clamp 25 and is clamped and fixed. The fixation is reliable, the operation is simple, and the difficulty is low.

[0048] ② The clamping hole 22 of one half frame 18 is put on the fixing protrusion 21 of the other half frame 18, and the end of the mounting rod 19 is clamped through the clamping groove 20 inside the half frame 18, so that the two half frames 18 are docked into a complete frame, and the mounting rod 19 is limited between the two half frames 18, and the cleaning rack 17 is assembled. The docking is simple, the operation difficulty is low, the mounting rod 19 is clamped by the two half frames 18 and cannot be freely disengaged, the installation is stable and reliable, and the fixing is in place in one step. There is no need to fix the mounting rod 19 separately, which replaces the bolt connection method, saving labor and convenience.

[0049] (b) Installing the skylight bracket 16 into the cleaning box 2 of the cleaning device: The guide rod 9 on the side of the cleaning box 2 is sleeved through the sleeve hole 24 at the bottom of the L-shaped base 23, so that the cleaning frame 17 is limited between the two guide rods 9, and the skylight bracket 16 is located in the cleaning box 2. The distance between the two guide rods 9 is fixed, which further limits the distance between the two half frames 18. The two half frames 18 cannot be freely disengaged, and the installation rod 19 cannot be freely disengaged from between the two half frames 18. The step-by-step restraint improves the assembly stability of the cleaning frame 17.

[0050] (c) Cleaning:

[0051] ① Start the liquid pump 4, which pumps the cleaning liquid in the liquid storage tank 3 into the inner cavity of the cleaning tank 2. The cleaning liquid is sprayed out through the nozzle 6 on the inner wall of the cleaning tank 2 to form a strong jet flow to flush the sunroof bracket 16. The impact effect is strong and impurities such as oil stains, metal debris, etc. attached to the surface of the sunroof bracket 16 are effectively washed off.

[0052] The servo motor 11 is started, and the servo motor 11 drives the cam 13 to rotate through the transmission shaft 12. The cam 13 intermittently pushes the transmission wheel 10 upward, so that the guide rod 9 reciprocates up and down, and the guide rod 9 drives the cleaning rack 17 to reciprocate up and down, so that the sunroof bracket 16 continuously stirs the cleaning liquid in the cleaning box 2. Compared with using a cylinder to drive the cleaning rack 17 to complete the lifting and reciprocating action, there are problems such as high difficulty in controlling the cylinder, high requirements for the comprehensive performance of the cylinder, and short service life of the cylinder.

[0053] Each skylight bracket 16 is hung independently in the cleaning box 2 without contacting each other to avoid collision and damage. In the initial flushing stage, the liquid level in the cleaning box 2 is low, and the skylight bracket 16 moving up and down constantly collides with the cleaning liquid. The collision effect is more conducive to the cleaning liquid to wash away impurities such as oil stains and metal debris attached to the surface of the skylight bracket 16; in the later flushing stage, the liquid level in the cleaning box 2 is high, and the skylight bracket 16 moving up and down constantly stirs the cleaning liquid, which improves the fluidity of the cleaning liquid, is conducive to the comprehensive contact between the cleaning liquid and each skylight bracket 16, and improves the impurity removal effect.

[0054] ② When the liquid level in the cleaning box 2 reaches the liquid level warning line, turn off the liquid pump 4, open the drain port at the bottom of the cleaning box 2 after 10-15 minutes, and drain the cleaning liquid into the waste liquid tank 5. During the drainage stage, the skylight bracket 16 that moves up and down continuously shakes off the cleaning liquid on the surface, which improves the drainage efficiency, does not require additional drying equipment, and reduces equipment costs.

[0055] (d) Taking out the sunroof brackets 16: After the sunroof brackets 16 are drained, the servo motor 11 is turned off, the cleaning rack 17 is removed, and then the sunroof brackets 16 are taken out to prepare for the cleaning of the next batch of sunroof brackets 16.

[0056] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
