Description

Technical Field

[0001] This invention relates to the technical field of adhesive application equipment, and in particular to a fully automatic adhesive application and coding machine. Background Technology

[0002] With the development of technology, people have invented all kinds of electronic products. Many electronic products are equipped with screens for human-computer interaction, so the demand for screens is increasing day by day. At the same time, with different usage requirements, different demands have arisen for the shape and type of screens.

[0003] Currently, electronic product manufacturers customize backlight screen components according to their needs. After these screen components are produced, insulating adhesive needs to be applied to the cables of the screen components according to the user's requirements. Then, the back of the screen is printed with codes. Therefore, workers need to flip the screen components to continue printing codes, resulting in high labor costs. Summary of the Invention

[0004] To address the issue of high labor costs, this application provides a fully automatic adhesive application and coding machine.

[0005] The above-mentioned objective of this invention is achieved through the following technical solution: a fully automatic adhesive applicator and coding machine, comprising:

[0006] The first conveying mechanism is used to convey screen components;

[0007] An adhesive applicator is used to apply adhesive to specific locations on screen components conveyed by a first conveying mechanism.

[0008] The alignment and imaging mechanism, located above the first conveying mechanism, is used to identify the position of the screen component on the first conveying mechanism so that the adhesive applicator can apply the adhesive to the specified position on the screen component.

[0009] The second conveying mechanism is used to convey screen components;

[0010] A flipping device for flipping the screen assembly on the first conveying mechanism and placing it on the second conveying mechanism; and

[0011] The inkjet printing device, located above the second conveying mechanism, is used to print ink on the back of the screen assembly passing below the inkjet printing device.

[0012] Along the conveying direction of the screen assembly, the second conveying mechanism is located downstream of the first conveying mechanism, and the reflectivity of the portion of the second conveying mechanism that contacts the screen assembly is less than the reflectivity of the portion of the first conveying mechanism that contacts the screen assembly.

[0013] By adopting the above technical solution, the screen components to be processed are conveyed by a conveying device. When the screen components are conveyed to the adhesive applicator, adhesive is applied to specific positions on the screen components. Then, the screen components are flipped by a flipping device to facilitate the printing of codes on the back of the screen components by a printing device. After that, the screen components can enter the subsequent processes. The entire process has low labor costs and is fully automated, resulting in high production efficiency.

[0014] Meanwhile, by setting the reflectivity of the part in contact with the screen component of the first conveying mechanism to be larger, it is easier for the alignment and imaging mechanism to identify the screen component and improve the accuracy of adhesive bonding; by setting the reflectivity of the part in contact with the screen component of the second conveying mechanism to be smaller, the accuracy of the inkjet printer in identifying the product can be improved, and the situation where the second conveying mechanism is inkjet printed due to the inkjet printer's identification error can be reduced to a certain extent.

[0015] Preferably, the second conveying mechanism includes a conveyor belt with an opening along the conveying direction of the screen assembly. When the screen assembly is conveyed on the conveyor belt, the screen assembly spans the opening. The inkjet printer includes a printhead that faces the opening.

[0016] By adopting the above technical solution, the opening allows the ink from the coding device to be sprayed into the opening after the coding device makes a mistake, which to some extent avoids the situation where the conveyor belt is easily smudged by ink during long-term use.

[0017] Preferably, the flipping device includes:

[0018] A rotating arm, rotatably mounted upstream of the second conveying mechanism, includes a free end that, when rotated, can rotate from above the first conveying mechanism into an opening; and

[0019] A suction cup, fixed to the free end, is used to adsorb the screen assembly on the first conveying mechanism. The outer diameter of the suction cup is not greater than the width of the opening.

[0020] By adopting the above technical solution, after the screen component is adsorbed by the suction cup, the suction cup will drive the screen component to rotate until the suction cup enters the opening. At this time, the screen component will be flipped over and will come into contact with the conveyor belt. By releasing the suction cup, the screen component can be placed on the conveyor belt. Starting the conveyor belt will transport the flipped screen component. Then, the suction cup will rotate back with the rotating arm to the side of the first conveyor mechanism to pick up the next screen component. This process can be repeated. The whole process is simple and convenient to operate, and the operation efficiency of flipping the screen component is high.

[0021] Preferably, a blocking member is provided on the side of the first conveying mechanism near the second conveying mechanism, and a first sensor is provided on the blocking member. When the screen assembly is conveyed to the side of the first conveying mechanism near the second conveying mechanism, it will be blocked by the blocking member, and when the screen assembly comes into contact with the blocking member, it will be sensed by the first sensor.

[0022] By adopting the above technical solution, in order to prevent the screen component from falling between the first and second conveying mechanisms and being damaged, a baffle is installed at the tail end of the first conveying mechanism. After the screen component is glued, it will be conveyed to contact the baffle. At this time, the first sensor is triggered, and the screen component can be flipped onto the second conveying mechanism by the flipping device. Throughout the process, the start and stop of the flipping device and the second conveying mechanism can be controlled by the first sensor, so that the flipping device and / or the second conveying device only work when a screen component passes by, which is more energy-efficient.

[0023] Preferably, the adhesive applicator includes:

[0024] Unwinding mechanism, used for unwinding the adhesive tape needed for winding;

[0025] An adhesive applicator assembly for adsorbing and attaching adhesive from the unwinding mechanism to the screen assembly on the first conveying mechanism; and

[0026] The photo positioning component is located on the moving path of the adhesive application component and is used to identify the adhesive on the adhesive application component to determine whether the adhesive is in the specified position.

[0027] By adopting the above technical solution, the position of the adhesive sticker adsorbed on the adhesive application component can be identified through the photo positioning component, ensuring the adhesion accuracy of the adhesive sticker when it is subsequently applied to the screen component. At the same time, the adhesive sticker on the adhesive application component can be discarded if the position of the adhesive sticker is offset or other problems occur.

[0028] Preferably, the adhesive application assembly includes:

[0029] Adhesive suction head, used to pick up adhesive tape; and

[0030] A robotic arm for applying adhesive is used to drive an adhesive suction head to pick up adhesive from the unwinding mechanism and attach it to the screen assembly on the first conveying mechanism.

[0031] The adhesive applicator can be detachably connected to the adhesive applicator robotic arm.

[0032] By adopting the above technical solution, and by making the adhesive applicator detachable, the adhesive applicator can be replaced when producing screens of different models or sizes, making the equipment adaptable to applying a variety of adhesives.

[0033] Preferably, the adhesive applicator is rotatably mounted on a mounting platform, the axis of rotation of which is arranged along the direction perpendicular to the screen assembly conveying plane, and the adhesive applicator head is detachably connected to the mounting platform.

[0034] By adopting the above technical solution, the adhesive applicator can be rotated via the mounting platform, which facilitates the adjustment of the position and angle of the adhesive according to the recognition position of the alignment and imaging mechanism, thereby improving the application accuracy of the adhesive.

[0035] Preferably, the image positioning component includes:

[0036] The housing has a shooting port at the top;

[0037] A camera, located inside the housing, with its shooting direction facing the shooting port side; and

[0038] A transparent cover is located between the shooting port and the camera, and the transparent cover is set at an angle. The housing is located on the lowest side of the transparent cover and has a discharge port for adhesive to pass through.

[0039] By adopting the above technical solution, when the camera determines that there is a problem with the position or quality of the adhesive, the adhesive application robot arm is controlled to release the adhesive. At this time, the adhesive will fall onto the inclined transparent cover and fall into the discharge port along the inclined transparent cover to be collected. After that, the adhesive application robot arm returns to the unwinding mechanism to pick up the material again, so as to avoid the situation where the screen component function is affected when the adhesive is not applied accurately.

[0040] Preferably, a second sensor for sensing the screen assembly is disposed above the first conveying mechanism, and the second sensor is located upstream of the adhesive applicator along the conveying direction of the screen assembly.

[0041] By adopting the above technical solution, the screen component on the first conveying mechanism is sensed. When the second sensor senses that a screen is passing by, the first conveying mechanism stops moving after a certain period of time according to the set requirements. At this time, the screen component will stop exactly below the alignment and photography mechanism, which makes it convenient for the alignment and photography mechanism to determine the position of the screen component.

[0042] Preferably, the first conveying mechanism includes a light-transmitting conveyor belt, the alignment and imaging mechanism is located above the light-transmitting conveyor belt, and a supplementary light is provided on the side of the light-transmitting conveyor belt away from the alignment and imaging mechanism;

[0043] Preferably, the light-transmitting conveyor belt is provided with indicator lines to indicate the shooting range of the alignment and imaging mechanism, and the indicator lines extend along the conveying direction of the screen assembly.

[0044] By adopting the above technical solution, the supplementary lighting can make the light-transmitting conveyor belt and the screen assembly more distinct, which facilitates the alignment and photography mechanism to photograph and inspect the screen assembly. The indicator lines can guide the operator to place the screen assembly in the area between the indicator lines, avoiding the situation where the screen assembly cannot be photographed and inspected when it is at the edge or outside the camera's shooting area.

[0045] In summary, the present invention has at least one of the following beneficial technical effects:

[0046] 1. First, adhesive is applied to the screen assembly using an adhesive applicator. Then, the screen assembly is flipped over using a flipping device and printed with ink. The entire process has low labor costs and is fully automated, resulting in high production efficiency.

[0047] 2. By setting a higher reflectivity at the contact point between the first conveying mechanism and the screen component, the alignment and imaging mechanism can easily identify the screen component, thus improving the accuracy of adhesive bonding. By setting a lower reflectivity at the contact point between the second conveying mechanism and the screen component, the accuracy of the inkjet printer in identifying the product can be improved, and the possibility of the second conveying mechanism being inkjet-printed due to an error in the inkjet printer's identification can be reduced to some extent.

[0063] Reference Figure 1 , 2 The present invention discloses a fully automatic adhesive application and coding machine, comprising a first conveying mechanism 1, an adhesive application device 2, an alignment and photographing mechanism 3, a second conveying mechanism 4, a flipping device 5, and a coding device 6; the first conveying mechanism 1 is located to the left of the second conveying mechanism 4, the flipping device 5 is located between the first conveying mechanism 1 and the second conveying mechanism 4, the alignment and photographing mechanism 3 is located above the first conveying mechanism 1, and the coding device 6 is located above the second conveying mechanism 4.

[0064] In use, the screen assembly requiring adhesive is placed on the first conveying mechanism 1 for transport. When it reaches below the alignment and imaging mechanism 3, the first conveying mechanism 1 stops transporting. Then, the alignment and imaging mechanism 3 detects and determines the position of the screen assembly. Then, the adhesive applicator 2 applies adhesive to the specific position of the screen assembly. After the adhesive is applied, the first conveying mechanism 1 continues to transport. When the screen assembly moves to the flipping device 5, the flipping device 5 flips the screen assembly 180 degrees so that the back of the screen assembly faces up and is placed on the second conveying mechanism 4 for continued transport. After the screen assembly passes the inkjet printer 6, inkjet printing will be applied to the back of the screen assembly, completing the production steps.

[0065] The first conveying mechanism 1 includes a light-transmitting conveyor belt 11 and conveyor rollers 12. The light-transmitting conveyor belt 11 has a certain degree of light transmittance. When light shines from one side of the light-transmitting conveyor belt 11, some light can pass through from the other side of the light-transmitting conveyor belt 11. In this embodiment, the light-transmitting conveyor belt 11 is a PU conveyor belt 41, and there are two conveyor rollers 12, which are arranged parallel to each other. The light-transmitting conveyor belt 11 is tightly stretched between the two conveyor rollers 12. In use, a supplementary light is provided below the light-transmitting conveyor belt 11. The supplementary light is always on during operation. When the screen component is placed on the light-transmitting conveyor belt 11 for conveying, since the screen component itself is not light-transmitting, it will create a clear light distinction on the light-transmitting conveyor belt 11. When the alignment and imaging mechanism 3 located above the light-transmitting conveyor belt 11 takes pictures to collect information, it can more accurately collect the position of the screen component, which is convenient for the subsequent adhesive applicator 2 to accurately apply adhesive.

[0066] Reference Figure 1 , 2 Since the imaging range of the alignment and imaging mechanism 3 is limited, indicator lines 13 are provided on the light-transmitting conveyor belt 11. In this embodiment, there are two indicator lines 13. The indicator lines 13 extend along the conveying direction of the light-transmitting conveyor belt 11 and are provided on the light-transmitting conveyor belt 11. The area between the two indicator lines 13 is within the imaging range of the alignment and imaging mechanism 3 and is located in the middle of the imaging range. When the screen assembly is placed on the light-transmitting conveyor belt 11, the screen assembly can be placed between the two indicator lines 13.

[0067] When the adhesive is applied by the adhesive applicator 2, the light-transmitting conveyor belt 11 is subjected to a certain vertical pressure, which can easily cause it to shake. Therefore, reinforcing ribs are provided inside the light-transmitting conveyor belt 11. In this embodiment, there are two reinforcing ribs, and their color is dark, such as black. The light-transmitting conveyor belt 11 is milky white in this embodiment, creating a clear distinction between the color of the reinforcing ribs and the light-transmitting conveyor belt 11. During normal use, the color of the reinforcing ribs can be observed through the light-transmitting conveyor belt 11. In this embodiment, the indicator line 13 is formed by the reinforcing ribs. During use, the reinforcing ribs increase the strength of the light-transmitting conveyor belt 11. Furthermore, the reinforcing ribs are located at both ends of the screen assembly. When the screen assembly is pressed by the adhesive applicator 2, the reinforcing ribs can share some of the pressure, making the light-transmitting conveyor belt 11 less prone to shaking during transport and improving the accuracy of adhesive application to the screen assembly. Therefore, by strengthening the reinforcing ribs, on the one hand, the shooting range of the alignment and imaging mechanism 3 can be indicated, and on the other hand, the light-transmitting conveyor belt 11 can be strengthened. Since the light-transmitting conveyor belt 11 needs to transmit light, the thickness of the light-transmitting conveyor belt 11 is relatively thin. By strengthening the reinforcing ribs, the light-transmitting conveyor belt 11 can have strong strength while transmitting light, so that the light-transmitting conveyor belt 11 is not prone to large deformation and shaking during the adhesive application process.

[0068] Reference Figure 1 , 2 A baffle 7 is provided at the right end of the first conveying mechanism 1. In this embodiment, refer to... Figure 3 As shown, the baffle 7 is a baffle fixed to the right end of the first conveyor mechanism 1. When the screen assembly is conveyed to the right end of the first conveyor mechanism 1, the screen assembly will stop conveying under the obstruction of the baffle 7. In order to prevent the first conveyor belt from continuing to convey after the baffle 7 comes into contact with the screen assembly, a first sensor 8 is provided on the baffle 7. When the screen assembly comes into contact with the baffle 7, the screen assembly will trigger the first sensor 8. At this time, the first sensor 8 will send a signal to stop the first conveyor.

[0069] Reference Figure 1 , 2 A second sensor 9 is provided on the left side of the first conveying mechanism 1. When the screen assembly is conveyed on the first conveying mechanism 1, the screen assembly will pass through the second sensor 9. The second sensor 9 can determine the position of the screen assembly and allow the first conveying mechanism 1 to stop moving after the screen assembly moves to the corresponding position. This makes it convenient for the alignment and photography mechanism 3 to take pictures of the screen assembly in time, and also makes it convenient for the adhesive applicator 2 to apply adhesive to the screen assembly.

[0070] Reference Figure 1 , 2The second conveying mechanism 4 includes a conveyor belt 41. An opening 42 is provided on the conveyor belt 41 along the conveying direction. In this embodiment, the conveyor belt 41 includes a first sub-belt and a second sub-belt, which are arranged side by side. The opening 42 is formed between the first sub-belt and the second sub-belt. When the screen assembly is conveyed on the second conveying mechanism 4, one end of the screen assembly is located on the first sub-belt and the other end is located on the second sub-belt, so that the screen assembly spans across the opening 42. The coding device 6 is located directly above the opening 42. The coding device 6 includes a printhead, which is set towards the opening 42. When the screen assembly is conveyed on the conveyor belt 41 and passes the printhead, the printhead will print a code onto the coding assembly. When the recognition is incorrect, the printhead will print a code into the opening 42, effectively preventing the coding device 6 from printing a code onto the conveyor belt 41 when the recognition is incorrect. The conveyor belt 41 can maintain a relatively clean state during long-term use and is not easy to contaminate the screen assembly.

[0071] In this embodiment, the conveyor belt 41 is dark black, and the reflectivity of the conveyor belt 41 is less than that of the light-transmitting conveyor belt 41. The lower reflectivity of the conveyor belt 41 can improve the recognition accuracy of the coding device 6, while the high reflectivity of the light-transmitting conveyor belt 11 can improve the photo recognition accuracy of the alignment and photo-taking mechanism 3.

[0072] Reference Figure 2 , 4 The flipping device 5 includes a rotating arm 51 and a suction cup 52. In this embodiment, a rotating rod 53 is provided at one end of the second conveying mechanism 4 near the first conveying mechanism 1. The rotating arm 51 is fixed on the rotating rod 53. A drive motor is connected to the rotating rod 53 to drive the rotating rod 53 to rotate forward and backward. The rotating rod 53 can drive the rotating arm 51 to rotate from the side of the first conveying mechanism 1 to the side of the second conveying mechanism 4, or drive the rotating arm 51 to rotate from the side of the second conveying mechanism 4 to the side of the first conveying mechanism 1. The end of the rotating arm 51 facing away from the rotating rod 53 is a free end 51a. The suction cup 52 is fixed at the free end 51a. When the rotating arm 51 drives the suction cup 52 to rotate to the side of the first conveying mechanism 1, the suction cup 52 can attract the screen assembly that is in contact with the blocking member 7. Then, when the rotating arm 51 rotates, the suction cup 52 will drive the screen assembly to rotate together until the suction cup 52 rotates into the opening 42 and the screen assembly contacts the conveyor belt 41. At this time, the suction cup 52 is released, and the screen assembly will be flipped over and fall onto the conveyor belt 41. The working principle of the suction cup 52 is to pick up the screen assembly by negative pressure.

[0073] The adhesive application device 2 includes an unwinding mechanism 21, an adhesive application assembly 22, and a camera positioning assembly 23. The adhesive application assembly 22 includes an adhesive application nozzle 22a and an adhesive application robotic arm 22b. A mounting platform 22c is rotatably connected to the adhesive application robotic arm 22b. The mounting platform 22c rotates around a vertical axis. The adhesive application nozzle 22a is detachably fixed to the mounting platform 22c. During use, the rotation angle of the adhesive application nozzle 22a can be adjusted by adjusting the rotation angle of the mounting platform 22c, which facilitates adjusting the adhesive angle according to the position of the screen assembly, resulting in higher bonding accuracy.

[0074] The unwinding mechanism 21 unwinds the rolled adhesive tape, facilitating the application robot arm 22b to pick up the tape. The application robot arm 22b then drives the application suction head 22a to pick up the tape from the unwinding mechanism 21 and apply it to the screen assembly on the first conveying mechanism 1. Figure 5 As shown, in this embodiment, the photo-taking and positioning component 23 includes a housing 23a, a camera, and a transparent cover 23b. A shooting port is provided at the upper end of the housing 23a, and the camera is located inside the housing 23a and is used to take pictures facing the shooting port at the upper end of the housing 23a, thereby photographing and recognizing the adhesive on the adhesive applicator 22a located above the shooting port at the upper end of the housing 23a. A transparent cover 23b is provided at the shooting port of the housing 23a, and the camera is located between the transparent cover 23b and the bottom of the housing 23a. The transparent cover 23b is tilted, and a discharge port 23c is provided on the lowest side of the housing 23a located near the transparent cover 23b. When the camera determines that there is a problem with the position or quality of the adhesive, the adhesive applicator 22a is controlled to release the adsorbed adhesive. At this time, the adhesive will fall onto the tilted transparent cover 23b and fall along the tilted transparent cover 23b into the discharge port 23c for collection. Afterwards, the adhesive applicator robotic arm 22b returns to the unwinding mechanism 21 to pick up the material again.

[0075] In use, the screen assembly is placed in the area between the indicator lines 13 on the light-transmitting conveyor belt 11. The screen assembly will then be conveyed by the light-transmitting conveyor belt 41. When the screen assembly passes the second sensor 9, the light-transmitting conveyor belt 41 is allowed to continue conveying for a period of time and then stop. At this time, the screen assembly will stop directly below the alignment and imaging mechanism 3. After the alignment and imaging mechanism 3 takes a picture of the screen assembly, it controls the adhesive applicator 2 to start the adhesive applicator work.

[0076] When applying adhesive, the adhesive application robot arm 22b controls the adhesive application suction head 22a to move to the unwinding mechanism 21 to pick up the adhesive. Then, according to the position detected by the alignment and imaging mechanism 3, the adhesive is applied to a specific position on the screen assembly. During this process, when the adhesive application suction head 22a picks up the adhesive, it will hover at the imaging port of the housing 23a. At this time, the camera inside the housing 23a will take a picture of the adhesive application suction head 22a to determine whether the adhesive position is correct. If it is incorrect, the adhesive application suction head 22a releases the adhesive, and the adhesive will fall into the housing 23a and exit from the discharge port 23c. If it is correct, it moves to the screen assembly for bonding, and then the adhesive application robot arm 22b returns to its original position.

[0077] After the adhesive is applied, the light-transmitting conveyor belt 11 will continue to convey the screen. When the screen assembly comes into contact with the baffle 7, the first sensor 8 is triggered. At this time, the light-transmitting conveyor belt 11 stops moving, and the flipping device 5 will flip the screen assembly that is in contact with the baffle 7. During the flipping, the rotating arm 51 rotates to the side of the light-transmitting conveyor belt 11 until the suction cup 52 comes into contact with the screen assembly and adsorbs the screen assembly. Then the rotating arm 51 rotates to the side of the conveyor belt 41 until the screen assembly comes into contact with the conveyor belt 41. At this time, the suction cup 52 will move into the opening 42 and then release the suction cup 52 to drive the screen assembly to be conveyed through the conveyor belt 41.

[0078] When the screen assembly is delivered to the side of the inkjet printer 6, the inkjet printer 6 will print the code on the back of the screen assembly; this cycle can be repeated to apply adhesive and print the code on multiple screen assemblies.

[0079] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
