Description

Technical Field

[0001] The present invention relates to the technical field of LED diffusion plates, and more particularly to a cleaning device for LED diffusion plates. Background Art

[0002] LED diffuser is a material used in LED lighting equipment. Its main function is to evenly distribute the light emitted by the light source and reduce light spots and glare. It is usually installed in front of the LED light source so that the light can be spread more evenly after passing through the diffuser, thus achieving a soft and uniform lighting effect.

[0003] During the production and processing of LED diffuser plates, the surface of the diffuser plates may be contaminated with impurities such as dust, oil, and residual chemicals. These impurities will affect the optical properties of the diffuser plates and prevent the light from being evenly distributed. In addition, in certain processing steps of the diffuser plates (such as coating or bonding), the surface cleanliness directly affects the adhesion of the coating or adhesive. Therefore, LED diffuser plates need to be cleaned during production. Cleaning can remove dirt from the surface of the diffuser plates, improve the uniformity of light distribution, ensure the smooth progress of subsequent processes, and ensure the reliability and durability of the product.

[0004] The traditional LED diffuser cleaning equipment is to transport the diffuser horizontally through the cleaning area and rinse it with a nozzle to achieve the purpose of cleaning the LED diffuser. The horizontal transportation of the diffuser is not only not conducive to the dirt being washed away by the water flow, but also inconvenient to remove the water stains on the surface of the diffuser, which brings inconvenience to the production and processing of the LED diffuser.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] The workpiece is fixed vertically by a suction cup, and then driven by a linear motor to move at a constant speed. During the movement, the workpiece can be sprayed with detergent or water, the brush roller can scrub the surface of the workpiece, and the wiper can scrape off the water droplets on the surface of the workpiece. Finally, the absorbent block and the absorbent strip can wipe the surface of the workpiece alternately to further absorb the moisture on the surface of the workpiece, thereby achieving the purpose of drying. The workpiece is fixed vertically, and the detergent or water can flow downward, which not only removes stains more efficiently, but also greatly reduces the residue of detergent or water, automatically removes most of the moisture, and facilitates the brush roller to perform all-round scrubbing.

[0023] In order to improve the brushing efficiency and effect of the brush roller, the brush roller is added to slide up and down, thereby increasing the brushing angle of the brush roller and improving the brushing efficiency and effect.

The squeezing plate and the squeezing plate cooperate with each other to squeeze the water-absorbing block together, squeeze out the water absorbed by the water-absorbing block, ensure that the water-absorbing block remains dry, and avoid the water-absorbing block being too saturated with water in the case of long-term water absorption, thereby reducing its water absorption efficiency.

[0024] During the lateral sliding of the sliding plate and the shell, the push plate can also be used to adjust whether the inner support bar enters the water wiping box. When the inner support bar is outside the water wiping box, the water absorption bar is exposed to the outside of the water wiping box, which can wipe the surface of the workpiece well, thereby absorbing water and drying; when the inner support bar is inside the water wiping box, the inner support bar can pull the water absorption bar back into the water absorption bar through the tow rope, and at the same time drive the water squeezing bar to squeeze the water absorption bar and discharge the water inside the water absorption bar, thereby drying the water absorption bar, ensuring the dryness of the water absorption bar, and improving the water absorption efficiency of the water absorption bar. Moreover, the moisture in the water-absorbing strip is discharged by sliding of the sliding plate and the shell. In this process, the water-absorbing block and the water-absorbing strip can be kept alternately entering and exiting the shell and the water-wiping box respectively, that is, when the water-absorbing block is exposed to the outside of the shell, the water-absorbing strip is inside the water-wiping box and is squeezed by the water-squeezing strip to discharge the moisture; when the water-absorbing block is squeezed and drained by the water-squeezing plate and the squeezing plate, the water-absorbing strip is exposed to the outside of the water-wiping box, so that the water-absorbing block and the water-absorbing strip can wipe the surface of the workpiece alternately, and fully cover the workpiece for drying.

Two strip grooves 72 are symmetrically provided on the side of the water wiping box 71 . A water absorbing strip 75 is slidably connected in each strip groove 72 .

[0042] The linear motor 13 moves on the guide rail 12 (the linear motor 13 is provided with a stator and a mover, the mover is usually a conductive coil or an iron core, and the stator is the part that provides the magnetic field. The electromagnetic induction and Ampere's law between the stator and the mover interact to make the mover move in a straight line direction). The support rod 15 provided on the top surface of each linear motor 13 fixes the workpiece 17 through the suction cup 16. The workpiece 17 is fixed vertically. The linear motor 13 passes through the side wall 22 in turn. The multiple nozzle groups 23 provided on the side wall 22 spray detergent or clean water to rinse the passed workpiece 17, which also There is a nozzle group 23 that sprays directly on the brush roller 35, thereby wetting the brush roller 35 to facilitate brushing of the workpiece 17; then the workpiece 17 passes through the brush roller 35, the brush roller 35 contacts the workpiece 17 and rotates, and the rotation of the brush roller 35 cooperates with the sprayed detergent or water to quickly and efficiently brush the stains on the surface of the workpiece 17; during the entire cleaning process, the detergent or water can flow downward along the vertically fixed workpiece 17, which not only more efficiently removes the stains, but also greatly reduces the detergent or water residue, and automatically removes most of the moisture, so that it is easier to dry the workpiece 17 later.

[0043] The workpiece 17 cleaned by the brush roller 35 continues to move, and the subsequent water absorbing blocks 64 and water absorbing strips 75 contact the surface of the workpiece 17 and alternately absorb the water stains on the surface of the workpiece 17 to ensure that the water stains on the surface of each workpiece 17 are completely dried.

[0044] Example 2: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 9 The conveying mechanism 1 further includes a base 11 installed at the bottom of the guide rail 12 , and a controller 14 is installed on the side of the linear motor 13 , and the linear motor 13 and the controller 14 are electrically connected.

[0045] The cleaning mechanism 2 also includes a water tank 21 installed on one side of the base 11, a side wall 22 installed on the side of the water tank 21, a first motor 24 installed on the upper end of the side wall 22, a cam 25 installed on the output end of the first motor 24, and two guide grooves 26 symmetrically arranged on the side of the side wall 22.

[0046] The scrubbing mechanism 3 also includes two lifting grooves 31 symmetrically arranged on the surface of the side wall 22, each lifting groove 31 is installed with a first spring 32, and the two lifting grooves 31 are respectively slidably connected with an upper bracket 33 and a lower bracket 36, the upper bracket 33 and the lower bracket 36 both abut against the corresponding first springs 32, and a second motor 34 is installed in the upper bracket 33, and the output end of the second motor 34 is installed at the top of the brush roller 35, and the bottom end of the brush roller 35 is rotatably connected to the lower bracket 36.

[0047] A controller 14 is installed on the side of the linear motor 13 , and the controller 14 can provide a variety of current modes (such as sine wave, trapezoidal wave, etc.) so that the linear motor 13 can slide smoothly on the guide rail 12 as needed.

[0048] Two lifting grooves 31 are symmetrically arranged on the surface of the side wall 22. Figure 3 As shown, an upper bracket 33 is elastically connected to the lifting groove 31 at the top of the side wall 22 through a first spring 32, and a lower bracket 36 is elastically connected to the lifting groove 31 at the bottom of the side wall 22 through a first spring 32. The second motor 34 installed on the upper bracket 33 drives the brush roller 35 to rotate, so as to brush the surface of the workpiece 17. At the same time, the first motor 24 inside the upper end of the side wall 22 drives the cam 25 to rotate slowly. Every time the cam 25 rotates one circle, it will conflict with and press down the second motor 34 once, and the second motor 34 is When the cam 25 is squeezed, the upper bracket 33 and the brush roller 35 will slide downward, and the upper bracket 33 will slide in the lifting groove 31 above the side wall 22, compressing the corresponding first spring 32. At the same time, the brush roller 35 will drive the lower bracket 36 to slide downward, and the lower bracket 36 will slide in the lifting groove 31 below the side wall 22, and compress the corresponding first spring 32. The up and down sliding of the brush roller 35 can add a cleaning dimension, which can not only brush the workpiece 17 horizontally, but also vertically, thereby further improving the cleaning efficiency and effect. The detergent or clean water sprayed by the nozzle group 23 and the sewage flowing down from the workpiece 17 flow directly downward and enter the water tank 21 between the base 11 and the side wall 22.

[0049] Example 3: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 9 A transmission mechanism 4 is provided on the upper bracket 33, and the transmission mechanism 4 includes a pressure block 41 fixed to the sides of the upper bracket 33 and the lower bracket 36. A wiper plate 42 is installed on the side of the side wall 22. Two groups of limiting sleeves 43 are symmetrically provided on the side of the side wall 22. Two sliding rods 44 are respectively slidably connected to the inside of the two groups of limiting sleeves 43, and the pressure block 41 abuts against one end of the corresponding sliding rod 44.

[0050] A drainage mechanism 5 is provided on the side of the side wall 22, and the drainage mechanism 5 includes an adjustment groove 51 provided on the surface of the side wall 22, and two retreat grooves 52 are symmetrically provided at the upper and lower ends of the adjustment groove 51, and a sliding plate 53 is slidably connected inside the adjustment groove 51, and a plurality of elastic ropes 54 are equidistantly installed inside the side wall 22, and the ends of the plurality of elastic ropes 54 are connected to one side of the sliding plate 53, and two protrusions 55 are symmetrically fixed at the upper and lower ends of the sliding plate 53, and the protrusions 55 are slidably connected to the corresponding retreat grooves 52, and a shell 56 is fixed on the sliding plate 53, and hanging plates 57 are fixed at the upper and lower ends of the shell 56, and the hanging plates 57 are slidably connected to the corresponding guide grooves 26, and the other ends of the two sliding rods 44 respectively abut against the sides of the corresponding hanging plates 57, and a push plate 58 is fixed to the other side of the sliding plate 53.

[0051] The water absorption mechanism 6 also includes a side groove 61 arranged on the side of the shell 56, and a plurality of second springs 62 are equidistantly installed inside the shell 56. An extrusion plate 63 is slidably connected inside the shell 56, and one end of the second spring 62 is installed on the surface of the extrusion plate 63. The water absorption block 64 is installed inside the shell 56, and the extrusion plate 63 contacts the side of the water absorption block 64.

[0052] The water wiping mechanism 7 also includes a water squeezing plate 73 and an extrusion block 74 fixed to the side of the water wiping box 71. Side slide plates 76 are symmetrically slidably connected on both sides of the inside of the water wiping box 71. A plurality of third springs 77 are installed on the side of each side slide plate 76. One end of the plurality of third springs 77 is installed inside the water wiping box 71. One side of each water absorbing strip 75 is installed on the surface of the corresponding side slide plate 76. A partition plate 78 is fixed in the middle of the upper and lower ends of the inside of the water wiping box 71.

[0053] After the workpiece 17 is brushed by the brush roller 35, the wiper plate 42 installed on the side of the side wall 22 will then come into contact with the workpiece 17 to scrape off the water stains on the surface of the workpiece 17, thereby reducing the drying pressure of the water absorption mechanism 6 and the water wiping mechanism 7; the workpiece 17 after passing through the wiper plate 42 successively enters the range of the water absorption mechanism 6 and the water wiping mechanism 7, the water absorption block 64 in the shell 56 and the water absorption strip 75 inside the water wiping box 71 are both sponges with excellent water absorption. When the workpiece 17 passes by, the water absorption block 64 and the water absorption strip 75 wipe the surface of the workpiece 17 alternately, and the moisture on the surface of the workpiece 17 is thoroughly absorbed, thereby achieving the effect of drying the workpiece 17.

[0054] After wiping the surface of the workpiece 17 for a long time, the water absorbing block 64 and the water absorbing strip 75 will absorb a large amount of water. This water will reduce the water absorption performance of the water absorbing block 64 and the water absorbing strip 75, making it difficult to completely dry the surface of the workpiece 17. It may even increase the moisture on the surface of the workpiece 17. Therefore, each time the upper bracket 33 is pushed downward by the cam 25, the upper bracket 33 and the lower bracket 36 will respectively drive the pressing block 41 on their respective sides to slide downward, and the pressing block 41 squeezes and pushes the slide bar 44 on the limiting sleeve 43 to slide to the left (such as the attached Figure 1When the sliding plate 53 slides in the inclined groove 52, the shell 56 drives the water absorbing material 54 to move along the water absorbing material 56, and the water absorbing material 54 is moved along the water absorbing material 56. The block 64 is gradually aligned with the inner side of the water squeezing plate 73 on the side of the water wiping box 71. At the same time, the side groove 61 on the side of the shell 56 is gradually aligned with the squeezing block 74. When the boss 55 enters the straight groove from the inclined groove, the water absorbing block 64 is just aligned with the inner side of the water squeezing plate 73, and the side groove 61 is just aligned with the squeezing block 74. Subsequently, during the sliding process of the boss 55 in the straight groove of the retreat groove 52, the inner side of the water squeezing plate 73 squeezes the outer side of the water absorbing block 64, and the squeezing block 74 is inserted into the side groove 61 and squeezes the squeezing plate 63 inside the shell 56, so that the squeezing plate 63 slides in the direction close to the water absorbing block 64. The sliding of the squeezing plate 63 not only lengthens the second spring 62 to store force for the second spring 62, but also squeezes the inner side of the water absorbing block 64. The squeezing plate 73 and the squeezing plate 63 cooperate with each other to squeeze the water absorbing block 64 together, thereby quickly squeezing out the water absorbed by the water absorbing block 64. The squeezed water flows out from both sides and the bottom of the water absorbing block 64 , and the water on both sides of the water absorbing block 64 can flow into the drainage groove 59 inside the shell 56 , thereby being quickly drained down, and the discharged water flows into the water tank 21 from the bottom end of the shell 56 .

[0055] When the cam 25 no longer interferes with the second motor 34, the first spring 32 in the lifting groove 31 pushes the upper bracket 33 and the lower bracket 36 to rise, and the upper bracket 33 and the lower bracket 36 drive the brush roller 35 to rise while driving the pressure block 41 on its side to rise, thereby releasing the slide bar 44, and the other end of the slide bar 44 gradually reduces the extrusion force on the hanging plate 57. At this time, the elastic rope 54 after storing force inside the side wall 22 pulls the sliding plate 53 to reset, and the sliding plate 53 drives the boss 55, the shell 56 and the hanging plate 57 to reset respectively. During the resetting process, the water squeezing plate 73 no longer interferes with the outer side of the water absorbing block 64; the squeezing block 74 detaches from the side groove 61, the squeezing plate 63 loses the squeezing of the squeezing block 74, and returns under the pull of the second spring 62, releasing the water absorbing block 64, and finally the water absorbing block 64 dries and expands to its initial state.

[0056] Example 4: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 9The water wiping box 71 is provided with a water squeezing mechanism 8 inside. The water squeezing mechanism 8 includes an inner support bar 84 slidably connected to the inside of the water wiping box 71. A pressure bar 81 is fixed on the side of the inner support bar 84. The pressure bar 81 is slidably connected to the inside of the side wall 22, and the push plate 58 abuts against the pressure bar 81. The upper and lower ends of the pressure bar 81 are fixed with limit blocks 82. Two limit grooves 83 are symmetrically provided inside the side wall 22. Each limit block 82 is slidably connected to the corresponding limit groove 83. The water wiping box 71 Fixed pulleys 85 are symmetrically arranged at both ends of the interior, and a number of towing ropes 86 are slidably connected to the corresponding fixed pulleys 85. One end of each towing rope 86 is connected to the side of the side slide 76, and the other end is connected to the side of the inner support bar 84. A number of fourth springs 87 are symmetrically installed on both sides of each partition 78. Two water squeezing strips 88 are symmetrically installed inside the water wiping box 71. One side of each water squeezing strip 88 abuts against the corresponding water absorbing strip 75, and one end of the corresponding fourth spring 87 is installed on the other side of the water squeezing strip 88.

[0057] The water absorbing strip 75 inside the water wiping box 71 also needs to be drained in time. When the water absorbing block 64 inside the shell 56 is exposed (that is, the water absorbing block 64 can contact the surface of the workpiece 17), the protruding column 55 is at the end of the inclined groove on the retreat groove 52, the sliding plate 53 and the shell 56 are at the position farthest from the surface of the side wall 22, and the push plate 58 on the other side of the sliding plate 53 is tightly against the pressure strip 81, so that the inner support strip 84 goes deep into the water wiping box 71, the inner support strip 84 pulls the tow rope 86 to slide, the tow rope 86 slides on the corresponding fixed pulley 85, and the tow rope 86 drives the side slide plate 76 to slide to the right (as shown in the attached figure). Fig. 9The side slide plate 76 compresses the third spring 77 and drives the water absorbing strip 75 to slide from the strip groove 72 into the water wiping box 71. At this time, the water absorbing strip 75 cannot contact the surface of the workpiece 17, and cannot absorb water and wipe. The water absorbing strip 75 entering the water wiping box 71 is between the side slide plate 76 and the water squeezing strip 88. At the same time, the inner support strip 84 extending deep into the water wiping box 71 squeezes the water squeezing strip 88 to make the water squeezing strip 88 slide. The water squeezing strip 88 stretches the fourth spring 87 and squeezes the water absorbing strip 75, flattening the water absorbing strip 75, thereby squeezing out the water absorbed in the water absorbing strip 75. That is, when the water absorbing block 64 contacts the surface of the workpiece 17 for drying, the water absorbing strip 75 will slide into the water wiping box 71 to squeeze and dry itself. By adjusting the linear motor 13 to drive the workpiece 17 to move at a speed and the timing of the water absorbing block 64 and the water absorbing strip 75 to pop out alternately, it is ensured that after the water absorbing block 64 wipes half of the surface area of ​​the workpiece 17, the water absorbing block 64 begins to retreat with the shell 56, and the water absorbing strip 75 begins to slide out of the water wiping box 71, and finally touches the surface of the workpiece 17 to just take over the other half of the unwiped area of ​​the workpiece 17. After the side slide 76 slides to the right, a cavity that runs vertically through is formed between its other end and the inner wall of the water wiping box 71. The cavity has the same function as the drainage groove 59. After the water absorbing strip 75 is pressed to squeeze out its own water, the water can be discharged into the cavity, and flows downward along the cavity, and finally drips into the water tank 21 below.

[0058] During the sliding process of the protruding column 55 along the inclined groove of the retreating groove 52, the sliding plate 53 drives the pushing plate 58 to slide to the right front (as shown in the attached figure). Figure 8 As shown in the orientation shown in the figure, the push plate 58 releases the compressed strip 81, and the compressed strip 81 loses the pressure of the push plate 58. Under the elastic force of the third spring 77 and the fourth spring 87, the two water squeezing strips 88 slide relative to the middle, gradually no longer squeezing the water absorbing strip 75, and at the same time, pushing the inner support strip 84 to the right, so that the inner support strip 84 slides to the outside of the water wiping box 71. At the same time, the third spring 77 pushes the side slide plate 76 to slide to the left to fill the previous cavity. The side slide plate 76 pulls the tow rope 86 to the left, and pulls the inner support strip 84 to the right through the fixed pulley 85, further making the inner support strip 84 slide to the outside of the water wiping box 71, and the inner support strip 84 drives the compressed strip 81 to slide to the right. As the side slide plate 76 slides to the left, the dried and expanded water-absorbing strip 75 is driven to slide out of the strip groove 72, and finally contacts the surface of the workpiece 17, and continues to wipe and absorb the water stains on the surface of the workpiece 17. The above process is the process in which the water-absorbing block 64 is gradually squeezed by the squeezing plate 73 and the squeezing plate 63. Therefore, when the water-absorbing strip 75 slides out of the strip groove 72 to dry the workpiece 17, the water-absorbing block 64 will squeeze out water and dry itself.

[0059] When the compression strip 81 slides inside the side wall 22 , the limit blocks 82 at the upper and lower ends thereof slide in the limit grooves 83 inside the side wall 22 , which can improve the stability of the compression strip 81 and the inner support strip 84 and reduce shaking.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
