Description

Technical Field

[0001] The present invention relates to the field of display module processing, and in particular to an automatic rotary assembly processing line for display modules. Background Art

[0002] The display screen is assembled from multiple layers, including reflective sheets, cell layers, light guide plates, projection light sources, diffusers, etc. The current technology is not efficient in the process of assembling display screens and cannot fully realize automated assembly.

[0003] Chinese patent CN112849966B discloses a method for assembling a display module, including step B1: a storage device in a feeding device places a corresponding film on a stacking template in a stacking device; step B2: a dispensing mechanical arm in the stacking device dispenses glue on the film in the stacking template; step B3: the assembled display module is placed into a flip clamping structure by a mechanical arm, and the flip clamping structure clamps the display module; step B4: in the process of the flip clamping structure clamping and flipping the display module, a pressure roller assembly simultaneously presses the display module to ensure the adhesion and vacuum state between each film; step B5: a material transfer assembly moves the pressed display module to the lower part of a labeling assembly, a reel assembly cuts the adhesive strip, and the cut adhesive strip is placed on the upper surface of the display module by the labeling assembly; step B6: the material transfer assembly rotates, moves the display module to the coding assembly, and the coding assembly codes the adhesive strip on the display module; step B7: the coded display module is processed by an electrostatic treatment assembly and transferred to the next process.

[0004] The above scheme realizes the automatic assembly of the display module, but in the existing rotary assembly processing line, there are no corresponding dust prevention measures on the main body of the rotary conveyor device, that is, when the display component is transferred between adjacent processes, the upper part of the display component is in an open state, and even in a dust-free workshop, it cannot be guaranteed to be completely dust-free. Even tiny dust will affect the display effect of the final product of the display component. Summary of the invention

[0005] In view of the above problems, an automated rotary assembly processing line for display modules is provided, wherein a dust removal unit is arranged between each existing assembly station, the cleaning unit is arranged on a dust removal shell, and a plurality of electrostatic racks are arranged on one side of the cleaning unit along the length direction of the dust removal shell. When the base drives the display module to rotate, the display module first passes through the cleaning unit and then passes through the electrostatic rack. This is because when the display module passes through the cleaning unit, dust will be generated during cleaning of the cleaning unit, and after the display module passes through the cleaning unit, the electrostatic rack can absorb the dust on the moving path of the display module, thereby avoiding the dust from reattaching to the display module. If the electrostatic rack and the cleaning unit are connected The arrangement direction is inverted, that is, when the display module is driven to rotate by the base, the display module first passes through the electrostatic rack and then passes through the cleaning unit. Although the display module first passes through the electrostatic rack to absorb dust, it still needs to be cleaned by the cleaning unit. The dust generated after cleaning by the cleaning unit will still adhere to the display module. It is worth noting that the display module arranged on the base is driven to rotate by the base to form an annular moving area, and the sealing shell completely covers the annular moving area, and the bottom of the sealing shell is slidably matched with the upper part of the base, and a ventilation groove is formed between the sealing shell and the upper part of the base. The display module on the base can pass through the ventilation groove when rotating, and the outside air is only The ventilation groove can be entered from both ends of the ventilation groove, so that the display module is in a semi-sealed state during the transportation process, which reduces the probability of external dust adhering to the display module. When in the dust removal mode, the electrostatic rack set on the flip shell is vertically downward and extends from the lower part of the flip shell. At this time, the extended length of the electrostatic rack is greater than the radius of the flip shell, which can improve the dust removal efficiency of the electrostatic rack after power-on. After the electrostatic rack has been running for a period of time, more dust is adsorbed on the electrostatic rack, and the flip shell starts to drive the electrostatic rack to rotate. Before this, the electrostatic rack first retracts into the flip shell, and then the flip shell drives the electrostatic rack to rotate 180 degrees, so that the electrostatic rack is vertically upward and rotates to the flip shell after the cleaning mode. A cleaning chamber is formed between the shell and the sealing shell, the electrostatic frame is located in the cleaning chamber, a spray port and an air inlet are provided on the sealing shell, the spray port sprays water, and the air inlet injects air into the cleaning chamber, and a discharge port is provided at the bottom of the flip shell, and the water after cleaning the electrostatic frame and the air injected into the cleaning chamber through the air inlet are discharged through the discharge port, thereby completing the self-cleaning of the electrostatic frame. This not only enables the electrostatic frame to complete self-cleaning, but also reduces the cleaning space, reduces the volume of the dust removal unit, and further enables the dust removal unit to adapt to the assembly processing line with a relatively dense distribution of workstations, thereby ensuring that the display module will not be contaminated by dust during transportation, and the electrostatic frame in the dust removal unit can be automatically cleaned.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A dust removal unit is arranged between each existing assembly station. The cleaning unit is arranged on the dust removal shell. Multiple electrostatic racks are arranged on one side of the cleaning unit along the length direction of the dust removal shell. When the base drives the display module to rotate, the display module passes through the cleaning unit first and then passes through the electrostatic rack. This is because when the display module passes through the cleaning unit, the cleaning unit will generate dust during cleaning. After the display module passes through the cleaning unit, the electrostatic rack can absorb the dust on the moving path of the display module, thereby avoiding the dust from reattaching to the display module. If the arrangement direction of the electrostatic rack and the cleaning unit is reversed, that is, the display module is driven to rotate by the base, When the display module moves, it first passes through the electrostatic rack and then passes through the cleaning unit. Although the display module first passes through the electrostatic rack to absorb dust, it still needs to be cleaned by the cleaning unit.

It is worth noting that the display module set on the base is driven to rotate by the base to form an annular moving area, and the sealing shell completely covers the annular moving area, and the bottom of the sealing shell is slidably matched with the upper part of the base, and a ventilation groove is formed between the sealing shell and the upper part of the base. The display module on the base can pass through the ventilation groove when rotating, and the outside air can only enter the ventilation groove from both ends of the ventilation groove. , so that the display module is in a semi-sealed state during the transportation process, reducing the probability of external dust adhering to the display module. When in the dust removal mode, the electrostatic rack set on the flip shell is vertically downward and extends from the lower part of the flip shell. At this time, the length of the electrostatic rack is greater than the radius of the flip shell, which can improve the dust removal efficiency of the electrostatic rack after power-on. After the electrostatic rack has been running for a period of time, there is a lot of dust adsorbed on the electrostatic rack, and the flip shell starts to drive the electrostatic rack to rotate. Before this, the electrostatic rack is first retracted into the flip shell, and then the flip shell drives the electrostatic rack to rotate 180 degrees, so that the electrostatic rack is vertically upward and rotated to the position between the flip shell and the sealing shell after the cleaning mode. A cleaning chamber is formed, and the electrostatic rack is located in the cleaning chamber. A spray port and an air inlet are provided on the sealing shell. The spray port sprays water, and the air inlet injects air into the cleaning chamber. A discharge port is provided at the bottom of the flip shell, and the water after cleaning the electrostatic rack and the air injected into the cleaning chamber through the air inlet are discharged through the discharge port, thereby completing the self-cleaning of the electrostatic rack. This not only enables the electrostatic rack to complete self-cleaning, but also reduces the cleaning space, reduces the volume of the dust removal unit, and further enables the dust removal unit to adapt to the assembly processing line with densely distributed workstations, thereby ensuring that the display module will not be contaminated by dust during transportation, and the electrostatic rack in the dust removal unit can be automatically cleaned.

When the flip shell is in the cleaning state, the length of the electrostatic frame extending from the flip shell is less than the radius of the flip shell, which increases the dust removal area of ​​the electrostatic frame in the dust removal mode and reduces the self-cleaning area of ​​the electrostatic frame in the cleaning mode.

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Reference Figure 1-Figure 4 , Figure 7 , Figure 8 , Fig.13 and Fig.14 : An automatic rotary assembly processing line for display modules, comprising a base 1 that receives a display module 4 and can drive the display module 4 to rotate, and a cleaning unit 2 arranged above the base 1; a dust removal unit 3 is arranged on the cleaning unit 2, and the dust removal unit 3 includes a dust removal shell 34, which is arranged on the upper part of the base 1. When the base 1 drives the display module 4 to rotate, the dust removal shell 34 does not rotate. Figure 5As shown, the cleaning unit 2 is arranged in the dust removal shell 34, and an electrostatic rack 31 is arranged along the rotation direction of the display module 4. The display module 4 first passes through the cleaning unit 2 and then passes through the electrostatic rack 31. A flip shell 32 is arranged on the electrostatic rack 31. The flip shell 32 is a semicircular structure. The electrostatic rack 31 is slidably arranged on the flip shell 32 in the vertical direction. A sealing shell 33 is horizontally arranged on the upper part of the flip shell 32. The sealing shell 33 is an arc structure. The flip shell 32 is rotatably arranged in the sealing shell 33 along the axis of the sealing shell 33. The electrostatic rack 31 rotates synchronously with the flip shell 32. The electrostatic rack 31 located on the flip shell 32 can slide along the radial direction of the flip shell 32. The flip shell 32 has a cleaning mode and a dust removal mode. In the dust removal mode, the electrostatic rack 31 on the flip shell 32 rotates to a vertically downward state, and the electrostatic rack 31 extends from the flip shell 32 in the vertical direction. In the cleaning mode, the electrostatic rack 31 on the flip shell 32 retracts into the flip shell 32, and at this time, the electrostatic rack 31 on the flip shell 32 is vertically facing upward.

[0037] An electromagnet 321 is provided at the bottom of the flip shell 32. When the electromagnet 321 is energized, it generates attraction for the electrostatic frame 31. When the flip shell 32 needs to switch from the dust removal mode to the cleaning mode, the electromagnet 321 is energized and generates attraction for the electrostatic frame 31. The electrostatic frame 31 retracts into the flip shell 32 under the attraction of the electromagnet 321. A first rotation driver 35 is provided at one end of the flip shell 32. The first rotation driver 35 is used to drive the flip shell 32 to rotate. The first rotation driver 35 is preferably a steering gear. The static electricity generation principle of the electrostatic frame 31 is as follows: the electrostatic frame 31 is connected to the positive pole of the high-voltage power supply and is grounded, and the flip shell 32 is connected to the negative pole of the high-voltage power supply. When the electrostatic frame 31 is in a vertical downward state, the high-voltage power supply energizes the electrostatic frame 31, so that the surrounding air can be ionized through the electrostatic frame 31, so that dust adheres to the electrostatic frame 31. The base 1 is a rotary drive. In the traditional display module 4 automatic assembly processing line, although a corresponding cleaning unit 2 is provided, the display module 4 is basically in an open state when being transported between different process stations, that is, dust in the outside air is easy to fall on the display module 4. If only the traditional cleaning unit 2 is used to clean the upper part of the display module 4, dust is easy to occur during the cleaning process, that is, the dust originally attached to the display module 4 flies up after being cleaned by the cleaning unit 2, and the movement track of the dust after flying up cannot be determined. There is a situation where the dust after flying up falls on the display module 4 again, which will lead to a poor cleaning effect of the cleaning unit 2. In order to avoid the above situation, a dust removal unit 3 is added to the cleaning unit 2. The traditional dust removal unit 3 cannot perform self-cleaning during dust removal, and usually needs to be shut down for cleaning, which seriously affects the work efficiency. In order to overcome the above problem, the dust removal unit 3 is improved. The specific working principle is as follows: a receiving groove is provided on the base 1, and the display module 4 needs to be placed in the receiving groove. Around the base 1 is provided with a plurality of workstations in a circle. After the display module 4 is placed on the base 1, the base 1 can drive the display module 4 to rotate around the various workstations. A dust removal unit 3 is provided between each existing assembly workstation. The cleaning unit 2 is provided in the dust removal shell 34. A plurality of electrostatic racks 31 are arranged on one side of the cleaning unit 2 along the length direction of the dust removal shell 34. When the base 1 drives the display module 4 to rotate, the display module 4 first passes through the cleaning unit 2 and then passes through the electrostatic rack 31. This is because when the display module 4 passes through the cleaning unit 2, the cleaning unit 2 When the display module 4 passes through the cleaning unit 2, dust will be generated. When the display module 4 passes through the cleaning unit 2, the electrostatic rack 31 can absorb the dust on the moving path of the display module 4, thereby preventing the dust from reattaching to the display module 4. If the arrangement directions of the electrostatic rack 31 and the cleaning unit 2 are reversed, that is, when the display module 4 is driven to rotate by the base 1, the display module 4 first passes through the electrostatic rack 31 and then passes through the cleaning unit 2, then although the display module 4 first passes through the electrostatic rack 31 to absorb the dust, it still needs to pass through the cleaning unit 2 for cleaning.The dust generated after cleaning by the cleaning unit 2 will still adhere to the display module 4. It is worth noting that the display module 4 arranged on the base 1 forms an annular moving area after being driven to rotate by the base 1. The sealing shell 33 completely covers the annular moving area, and the bottom of the sealing shell 33 slides with the upper part of the base 1. A ventilation groove is formed between the sealing shell 33 and the upper part of the base 1. The display module 4 located on the base 1 can pass through the ventilation groove when rotating, and the outside air can only enter the ventilation groove from both ends of the ventilation groove, so that the display module 4 is in a semi-sealed state during the transportation process, which reduces the probability of external dust adhering to the display module 4. When in the dust removal mode, the electrostatic frame 31 arranged on the flip shell 32 is vertically downward and extends from the lower part of the flip shell 32. At this time, the extending length of the electrostatic frame 31 is greater than the radius of the flip shell 32, which can improve the dust removal efficiency of the electrostatic frame 31 after power-on. After the electrostatic frame 31 has been running for a period of time, the electrostatic frame There is a lot of dust adsorbed on 31, and the flip shell 32 starts to drive the electrostatic rack 31 to rotate. Before this, the electrostatic rack 31 first retracts into the flip shell 32, and then the flip shell 32 drives the electrostatic rack 31 to rotate 180 degrees, so that the electrostatic rack 31 is vertically facing upward. After rotating to the cleaning mode, a cleaning chamber is formed between the flip shell 32 and the sealing shell 33. The electrostatic rack 31 is located in the cleaning chamber. The sealing shell 33 is provided with a spray port 331 and an air inlet 332. The spray port 331 sprays water, and the air inlet 332 injects air into the cleaning chamber. The bottom of the flip shell 32 is provided with an exhaust port 333. The water after cleaning the electrostatic rack 31 and the air injected into the cleaning chamber by the air inlet 332 are discharged through the exhaust port 333. In this way, the self-cleaning of the electrostatic rack 31 is completed. In this way, not only can the electrostatic rack 31 complete self-cleaning, but also reduce the cleaning space, so that the volume of the dust removal unit 3 is reduced, and the dust removal unit 3 can adapt to the assembly processing line with densely distributed workstations.

[0038] Reference Figure 1-Figure 14 : At least two electrostatic racks 31 are provided, and all the electrostatic racks 31 provided in the dust removal shell 34 are arranged along the length direction of the dust removal shell 34. When the display module 4 is supported on the base 1, at least one electrostatic rack 31 is in a state of extending from the lower part of the flip shell 32.

[0039] Since the flip shell 32 has a cleaning mode and a dust removal mode, when the flip shell 32 is in the cleaning mode, the electrostatic rack 31 will retract into the flip shell 32, and at this time the electrostatic rack 31 is in the cleaning chamber, and the electrostatic rack 31 is in a power-off state. Therefore, the electrostatic rack 31 in the cleaning mode cannot perform dust removal. Therefore, if all the flip shells 32 are in the cleaning mode, the dust removal function of the dust removal unit 3 will be lost. In order to avoid the above situation, at least one electrostatic rack 31 needs to be in the dust removal mode.

[0040] Reference Figure 6 and Figure 8 When the flip shell 32 switches from the dust removal mode to the cleaning mode, the electrostatic frame 31 extending from the flip shell 32 retracts into the flip shell 32. When the flip shell 32 switches to the cleaning mode, the electrostatic frame 31 in the flip shell 32 faces vertically upward, and the sealing shell 33 seals the flip shell 32 to form a cleaning chamber. Spray ports 331 and air inlets 332 are alternately arranged on the sealing shell 33 along the length direction of the sealing shell 33. An exhaust port 333 is arranged at the bottom of the flip shell 32. The water sprayed from the spray port 331 and the air injected from the air inlet 332 are all discharged through the exhaust port 333.

[0041] When the electrostatic rack 31 needs to be cleaned, the electrostatic rack 31 is retracted into the flip shell 32, and then the flip shell 32 drives the electrostatic rack 31 to rotate to a vertically upward state. At this time, the sealing shell 33 seals the flip shell 32, the spray port 331 sprays clean water, and the air inlet 332 also injects gas. The water flow sprayed from the spray port 331 and the air injected from the air inlet 332 act together on the dust attached to the electrostatic rack 31. The sprayed water flow can make the charged impurities lose their adsorption force quickly, and the flowing air flow can also blow off the dust attached to the electrostatic rack 31 It is worth noting that although the spray port 331 is started synchronously with the air inlet 332, the spray port 331 will stop before the air inlet 332, that is, after the water flow in the spray port 331 stops spraying, the air inlet 332 is still in operation, and the air inlet 332 continues to blow air into the cleaning chamber, so that the electrostatic rack 31 is dried by the flowing air, ensuring that after the flip shell 32 drives the electrostatic rack 31 to rotate to a vertically downward state, the electrostatic rack 31 extending from the flip shell 32 is in a dry state, thereby improving the dust removal effect of the electrostatic rack 31.

[0042] Reference Figure 6 : A first one-way valve is provided on both the spray port 331 and the air inlet 332. The water used to clean the electrostatic rack 31 enters the cleaning chamber through the first one-way valve corresponding to the spray port 331. The air used to clean the electrostatic rack 31 enters the cleaning chamber through the first one-way valve corresponding to the air inlet 332. A second one-way valve 334 is provided on the exhaust port 333. A temporary storage chamber 335 is provided on the side of the second one-way valve 334 away from the exhaust port 333. The air and water in the cleaning chamber can enter the temporary storage chamber 335 through the second one-way valve 334.

[0043] During cleaning, the water and air entering the cleaning chamber through the spray port 331 and the air inlet 332 are discharged into the temporary storage chamber 335 through the discharge port 333. The water entering the temporary storage chamber 335 will be temporarily stored in the temporary storage chamber 335, and the air entering the temporary storage chamber 335 will be directly discharged to the outside. The water in the temporary storage chamber 335 will not be discharged until the flip shell 32 rotates to the dust removal mode. Since the flip shell 32 needs to rotate around the axis of the sealing shell 33 when switching between the cleaning mode and the dust removal mode, if the second one-way valve 334 is not provided on the discharge port 333, when the flip shell 32 is flipped, the water in the temporary storage chamber 335 will flow back from the drain port, thus causing the display module 4 to be contaminated. The above situation can be avoided by providing the second one-way valve 334.

[0044] Reference Fig.11 and Fig.12 : A collecting pipe 338 is connected to one side of the temporary storage chamber 335, and the collecting pipe 338 rotates synchronously with the flip shell 32. A three-way pipe 336 is arranged on the side of the collecting pipe 338 away from the temporary storage chamber 335. The three-way pipe 336 rotates with the collecting pipe 338, and an air pump 337 is arranged on the upper part of the three-way pipe 336. After the flip shell 32 is switched from the cleaning mode to the dust removal mode, the air pump 337 is started, and the air pump 337 pumps the water in the temporary storage chamber 335 through the three-way pipe 336 and the collecting pipe 338.

[0045] The connection between the collecting pipe 338 and the temporary storage chamber 335 is located at the upper part of the temporary storage chamber 335. When the flip shell 32 is switched from the cleaning mode to the dust removal mode, the water in the temporary storage chamber 335 is flipped, and the connection between the collecting pipe 338 and the temporary storage chamber 335 is located at the lower part of the temporary storage chamber 335. In this way, the water in the temporary storage chamber 335 can be smoothly discharged under the action of the air pump 337. Since the air pump 337 is arranged at the upper part of the three-way pipe 336, when the air pump 337 is running, the air can be discharged through the air pump 337, and the water in the temporary storage chamber 335 is discharged through the lower part of the three-way pipe 336. The air pump 337 is still in operation after the flip shell 32 is flipped. In addition to discharging the water in the temporary storage chamber 335, the air pump 337 can also inhale the air in the ventilation groove through the discharge port 333, so that part of the air circulating in the ventilation groove rises, and then more air flows through the electrostatic rack 31, so that the dust removal effect of the electrostatic rack 31 is improved.

[0046] Reference Figure 1-Figure 14 When the flip shell 32 is in the dust removal state, the length of the electrostatic frame 31 extending out is greater than the radius of the flip shell 32; when the flip shell 32 is in the cleaning state, the length of the electrostatic frame 31 extending out from the flip shell 32 is less than the radius of the flip shell 32.

[0047] This improves the workpiece utilization rate and reduces the volume of the dust removal unit 3.

[0048] Reference Figure 5 , Figure 7 , Figure 8 and Fig.11 : The bottom of the dust removal shell 34 is slidably matched with the upper part of the base 1, and a ventilation groove is formed between the bottom of the dust removal shell 34 and the upper part of the base 1, a blowing unit 5 is arranged between the dust removal unit 3 and the cleaning unit 2, and a blowing unit 5 is also arranged on the side of the dust removal unit 3 away from the cleaning unit 2, the blowing unit 5 includes a first fan 51, and the first fan 51 blows the filtered air into the ventilation groove.

[0049] Reference Figure 7 : Second fans 52 are respectively arranged at both ends of the ventilation groove. The two second fans 52 have the same power. The second fans 52 are used to discharge the air in the ventilation groove.

[0050] The first fan 51 injects filtered air into the ventilation groove, and then the air injected into the ventilation groove is discharged through the second fans 52 at both ends of the ventilation groove, so that the outside air cannot flow into the ventilation groove, and the dust mixed in the air cannot enter the ventilation groove, thereby ensuring that the display module 4 will not be contaminated by external dust during transportation.

[0051] Reference Figure 5 , Figure 7 and Figure 8 The cleaning unit 2 includes a sprayer 21 that can spray cleaning liquid and a wiping roller 22 arranged on one side of the sprayer 21 to wipe the upper part of the display module 4. The wiping roller 22 always rotates around the axis of the wiping roller 22. The display module 4 in transportation first passes through the sprayer 21 and then passes through the wiping roller 22.

[0052] The outer sleeve of the wiping roller 22 is provided with a water-absorbing flexible material, such as a sponge, etc. After the sprayer 21 sprays the cleaning liquid on the display module 4, the wiping roller 22 wipes off the cleaning liquid remaining on the display module 4. A driving unit 23 for driving the wiping roller 22 to rotate is provided at one end of the wiping roller 22. The driving unit 23 includes a second rotation driver 231, a gear 232 and a gear ring 233. The gear ring 233 is fixedly arranged at the end of the wiping roller 22, and the gear 232 is rotatably arranged on one side of the gear ring 233. The gear 232 and the gear ring 233 are meshed with each other. The second rotation driver 231 is provided at the end of the wiping roller 22. The actuator 231 is arranged at the end of the gear 232 and can drive the gear 232 to rotate. The second rotation driver 231 is preferably a servo motor. If the wiping roller 22 is always in a stationary state, the wiping roller 22 always passes through the same position to detect the display module 4. Not only is the friction force large, which can easily cause the wiping roller 22 to wear, but the wiping roller 22 is always in contact with the upper part of the display module 4 at the same place. The humidity at the contact position between the wiping roller 22 and the display module 4 continues to rise. As the processing continues, the water absorption of the wiping roller 22 on the display module 4 is reduced.

[0053] Reference Figure 7-Figure 9 : A drying unit 24 is arranged on the wiping roller 22, and the drying unit 24 can dry the rotating wiping roller 22. The drying unit 24 includes a heat pipe 242 arranged in the wiping roller 22 along the axis of the wiping roller 22, and a plurality of heat conduction holes 343 are evenly arranged on the upper part of the heat pipe 242 along the extension direction of the heat pipe 242. A heating pump 241 is connected to the end of the heat pipe 242, and the heating pump 241 heats the air and injects it into the heat pipe 242.

[0054] In this way, the wiping roller 22 rotates after wiping the upper part of the display module 4 . When the wiping roller 22 rotates to the upper part of the heat-conducting hole 343 , the hot air ejected from the heat-conducting hole 343 can dry the wiping roller 22 .

[0055] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
