Description

Technical Field

[0001] The invention belongs to the field related to LED display screen processing, and in particular relates to a fine processing method for an LED display screen. Background Art

[0002] There are many electronic boards in the structure of LED display screens. During the manufacturing process, a considerable number of electronic components need to be installed on the electronic substrate board. Originally, the electronic components can be installed after drilling holes in the substrate board, but this will increase its thickness and make heat dissipation more difficult. Therefore, the substrate board is slotted and glue is applied in the slot, so that some electronic components can be stuck in the slot. Due to the existence of the slot, the final thickness is reduced, the density is reduced, and the heat dissipation is accelerated. However, the substrate board is brittle and has a lot of dust. It is easy to crack during the slotting process and a lot of dust will appear, making the slotting difficult and the processing inconvenient. Therefore, it is of great significance to design a precision equipment that can effectively slot and glue the LED substrate board. Summary of the invention

[0038] Furthermore, a dust suction chamber 27 is provided on the side wall on the other side of the second slider 41, a dust suction hose 46 is connected to the bottom of the dust suction chamber 27, a dust suction chamber connecting pipe 28 is connected to the top of the dust suction chamber 27, and a vacuum cleaner 26 is provided on one side of the dust suction chamber 27 on the other clamping cylinder 21, and the vacuum cleaner 26 and the dust suction chamber connecting pipe 28 are connected to each other through a hose.

[0039] Working principle: In the initial state, the movable platform 19 is arranged on the outer side of the top of the processing box 10. At this time, the sealing slide 16 is arranged on both sides of the discharge port 15. The second slider 41 will move the push pipe 42 and the dust suction chamber 27 above the vacuum cleaner 26.

[0040] The operator can place the LED substrate plate that needs to be cut and coated with glue on the upper end surface of the movable table 19, and clamp the LED substrate plate between the two sliding connecting plates 38, so as to form pre-tightening through the elasticity of the sliding groove 36. At this time, the pushing cylinder 14 arranged at the bottom of the processing box 10 is started, and the pushing cylinder 14 pulls the internal first piston push rod 18 to move downward, thereby pulling the movable table 19 arranged at one end of the top of the first piston push rod 18 to move downward until the upper end surface of the movable table 19 is flush with the upper end surface of the fixed ring table 20 and then stops moving.

[0041] At this time, the clamping cylinder 21 arranged at both ends of the fixed ring platform 20 is started, and the clamping cylinder 21 pushes the internal second piston push rod 23 to move outward, thereby pushing the abutment block 67 arranged at one end of the second piston push rod 23 to move outward, thereby pushing the elastic tube 68 arranged in the abutment block 67 to move outward, thereby pushing the elastic rod 71 arranged in the elastic tube 68 to move outward, so that the elastic rod 71 extends out of the elastic tube 68 One end gradually fits to the back of the sliding connecting plate 38, thereby pushing the sliding connecting plate 38 to gradually clamp the substrate plate. During the clamping process, when the substrate plate is subjected to a certain pressure, the elastic rod 71 will be subjected to pressure and move inward, so that the bottom end of the elastic rod 71 contacts the generator 70 at the bottom of the elastic tube 68, so that the generator 70 generates a signal, thereby sending a signal to stop the increase of the clamping force, thereby avoiding the substrate plate from being clamped and damaged. In this relationship, since there is a partition between the two elastic blocks 66 for easy placement, and the sliding slot 36 is also pre-tightened against the sliding bottom plate 39, it can prevent deviation during the downward movement. At this time, the operator can observe through the display screen 11 and set the slot track through the operating knob 13 and the operating panel 12.

[0042] At this time, the two first drive motors 29 arranged on one side of the fixed ring table 20 are started, and the output end of the first drive motor 29 drives the first screw rod 31 to rotate, thereby driving the first slider 32 arranged on the first screw rod 31 to move, thereby driving the connecting bridge plate 34 arranged on the first slider 32 to move, thereby driving the pushing pipe 42 arranged under the connecting bridge plate 34 to move onto the LED substrate plate.

[0043] At this time, the second driving motor 33 arranged on one side of the connecting bridge plate 34 is started, and the output end of the second driving motor 33 drives the second screw rod 40 to rotate, thereby driving the second slider 41 arranged on the second screw rod 40 to move, thereby driving the pushing pipe 42 arranged at the bottom of the second slider 41 to move to the position where the notch cutting and gluing are required. At this time, the pushing pipe 42 is started, and the pushing pipe 42 starts to inhale air through the first air inlet 43 arranged on one side, thereby pushing the pushing rod 45 in the pushing pipe 42 to move downward, thereby pushing the horn cover 50 arranged at the bottom of the pushing rod 45 to move downward, thereby pushing the slotted drill bit 49 arranged at the center of the bottom of the horn cover 50 to move downward. During the movement, the third driving motor 51 arranged on one side of the top of the horn cover 50 is started, and the output end of the third driving motor 51 drives the first gear 52 to rotate, thereby driving the second gear 53 meshing therewith to rotate, thereby driving the slotted drill bit 49 at the center of the second gear 53 to rotate, so that when the cone head of the slotted drill bit 49 contacts the surface of the LED substrate board, it can go out of the notch on its surface.

[0044] During the process of making the groove, the second air inlet 55 arranged on the side of the push rod 45 starts to take in air, thereby injecting gas into the jet pipe 54. At this time, the heating block 56 arranged in the jet pipe 54 starts to heat, thereby converting the gas entering the jet pipe 54 into hot air, and the hot air will be ejected outward through the jet port 72 at the bottom of the jet pipe 54. The hot air will rotate when the slotting drill bit 49 is rotated and ejected during the slotting process. On the one hand, this design can remove impurities generated in the groove to ensure that it will not be affected during the slotting process. On the other hand, the groove can be preheated to facilitate subsequent glue coating.

[0045] During the grooving process, the dust suction chamber 27 arranged on one side of the pushing pipe 42 is started, and the dust suction chamber 27 is ventilated with the vacuum cleaner 26 through the dust suction chamber connecting pipe 28, so that the dust suction chamber 27 generates suction, so that the vacuum hose 46 at the bottom of the dust suction chamber 27 starts to perform vacuuming, thereby cleaning the dust generated by the grooving and blown to other places by the air jet 72. In this relationship, since the trumpet cover 50 is set as a trumpet mouth, the opened place will be covered during the grooving and gluing process, and the dirt will not be moved to other places, thereby facilitating cleaning.

[0046] During the grooving process, the photometric plate 24 arranged in the movable platform 19 is started, and the photometric plate 24 projects a light beam through the photometric hole 35 arranged on the top. At this time, the slotted part will transmit light to the top due to the thinning of the plate surface, and then be received by the light spectrum receiving plate 57 in the horn cover 50. At this time, the spray chamber 58 arranged on one side of the pushing pipe 42 is started, and the spray chamber 58 will pour the glue in the glue sprayer 25 into the spray chamber 58 through the hose. At this time, the fourth drive motor 62 arranged at one end of the spray chamber 58 is started, and the output end of the fourth drive motor 62 drives the rotating rod 61 to rotate, thereby driving the rotating impeller 59 arranged on the rotating rod 61 to rotate, so that the glue inside the spray chamber 58 can be driven to be injected to the bottom.

[0047] When the fourth drive motor 62 is started, the magnetic block 75 disposed in the sliding ring seat 76 will start to generate a magnetic force of the same polarity as the magnetic rod 73, thereby pushing the magnetic rod 73 disposed above the magnetic block 75 to move upward, thereby pushing the ring plate 65 disposed at the top of the magnetic rod 73 to move upward, thereby driving the sliding blocking block 63 disposed at the bottom of the center of the ring plate 65 to move upward, thereby causing the sealing fit between the sliding blocking block 63 and the fixed blocking block 64 to disappear, thereby causing the paint hose 47 to be in a through state. In this relationship, the magnetic force of the magnetic block 75 is proportional to the light transmittance received by the horn cover 50, thereby controlling the lifting height of the sliding blocking block 63, thereby adjusting the size of the through-hole and the flow rate, thereby ensuring that the amount of glue applied is proportional to the size of the slot opening.

[0048] The sprayed glue will be sprayed onto the slot mouth and then pressed by the rotating coating wheel 48. Since the rotating coating wheel 48 is set to rotate, it can move in conjunction with the movement trajectory of the slotting drill bit 49 to ensure accurate gluing. The setting of the jet nozzle 72 to preheat the slot before gluing can enable the colloid to adhere better to the slot during the gluing process.

[0049] After the processing is completed, the pushing pipe 42 will move to one side, and the clamping cylinder 21 will release the clamping. At this time, the lifting cylinder 14 will push the first piston push rod 18 to move upward, and the sealing slide 16 will also open, and the operator can take it from the top.
