Description

Technical Field

[0001] This invention belongs to the field of automation equipment technology, specifically a device for power-on detection and label removal / removal of a display screen. Background Technology

[0002] With economic development, electronic products are being used more and more widely, and LCD screens are an important component of these products. Therefore, all types of screens used in applications such as mobile phones, tablets, and monitors require power-on testing during the production process. Only after passing the power-on test can they be released to the market. In addition, to achieve product traceability, existing display screens are required to have traceability labels (i.e., QR codes) with product information affixed to their surfaces before leaving the factory. Through the traceability label, all information about the product from raw material procurement to product delivery can be found.

[0003] The existing power-on testing equipment and label-removing equipment for display screens are designed independently. Display screens are tested in batches before being transferred to the label-removing equipment for label removal. This makes it impossible to perform the label removal process immediately after a product is tested for power-on, resulting in low overall production efficiency. Summary of the Invention

[0004] To address the problems mentioned above, this invention provides a fully automatic power-on detection and label-removing device for display screens. This device integrates power-on detection and label-removing of products, enabling the label-removing process to be performed immediately after a product has undergone power-on detection, thus greatly improving product production efficiency.

[0005] The present invention adopts the following technical solution:

[0006] A fully automatic power-on detection and label-removing device for display screens includes a frame, an upstream feeding platform, a marble initial inspection platform, a power-on detection mechanism, a transfer platform, a label-removing mechanism, a material throwing mechanism, and a finished product unloading mechanism, sequentially arranged on the frame, wherein:

[0007] A feeding and handling arm is provided between the upstream feeding platform and the transfer platform. The feeding and handling arm moves the display screen on the upstream feeding platform to the marble preliminary inspection platform, and moves the display screen on the marble preliminary inspection platform that has completed inspection to the power-on testing mechanism and / or the transfer platform.

[0008] A material handling arm is installed between the transfer platform and the finished product unloading mechanism. The material handling arm moves the display screen on the transfer platform to the labeling mechanism or the throwing mechanism. After the labeling mechanism completes the labeling of the display screen, the material handling arm moves it to the finished product unloading mechanism.

[0009] Furthermore, a feeding correction component is provided on the side of the upstream feeding platform. The feeding correction component includes a first push rod that moves along the X direction and a second push rod that moves along the Y direction. The first push rod and the second push rod perform initial positioning of the display screen on the upstream feeding platform.

[0010] Furthermore, the feeding and handling arm includes a feeding arm, with an upper barcode scanner at the front end and a displacement laser sensor at the rear end. The movement of the feeding arm drives the upper barcode scanner and the displacement laser sensor to move, causing the displacement laser sensor to reciprocate on the marble initial inspection platform. There are two displacement laser sensors, spaced apart at the rear end of the feeding arm. The two displacement laser sensors are used to test the thickness of the four corners of the display screen.

[0011] Furthermore, the marble initial inspection platform is equipped with a lower barcode scanner at the front end, which is slidably positioned in the Y-axis direction. The marble initial inspection platform is equipped with a positioning camera at the rear end, which takes pictures and positions the FPC on the display screen.

[0012] Furthermore, the marble preliminary inspection platform is provided with two through holes, one of which contains a vacuum suction cup and the other contains a fiber optic sensor. Below the marble preliminary inspection platform is a slide rail extending along the Y-axis, and the marble platform is slidably connected to the slide rail.

[0013] Furthermore, the power-on testing mechanism includes at least one testing platform arranged along the X-axis direction. The testing platform is mounted on a first Y-axis moving module. The end of the first Y-axis moving module is provided with a test box that matches the testing platform. The testing platform is provided with a lower needle mold, which has multiple holes to match different models of display screens. The test box is provided with an upper needle mold that mates with the lower needle mold. A manual slide is installed on the test box to adjust the position of the upper needle mold.

[0014] Furthermore, the power-on testing mechanism includes five testing platforms arranged side by side along the X-axis, five test boxes on opposite sides of the five testing platforms, and all five test boxes are mounted on a mounting platform. The mounting platform is slidably connected to the frame along the X-axis by a manually adjustable screw assembly.

[0015] Furthermore, the label-removing mechanism includes a display screen transfer module, an easy-tear label feeding module, a printing module, and a label-removing moving module. The display screen transfer module includes a second Y-axis moving module and a label-removing platform disposed on the second Y-axis moving module. The easy-tear label feeding module is disposed on one side of the second Y-axis moving module.

[0016] The label-tear and label-applying moving module includes a gantry spanning both sides of the second Y-axis moving module along the X-axis direction, a first X-axis moving module and a second X-axis moving module respectively disposed on both sides of the gantry. A label-tearing component is installed on the first X-axis moving module, and a label-applying component is installed on the second X-axis moving module. The label-tearing component moves along the X-axis to the easy-tear label feeding module to pick up the easy-tear label, and the label-applying component moves to the printing module to pick up the label.

[0017] Furthermore, the unloading and handling arm includes a third X-axis moving module, a label-tear loading and handling arm located at the front end of the third X-axis moving module, and a finished product unloading and handling arm located at the rear end of the third X-axis moving module. The finished product unloading and handling arm includes an unloading suction cup and a sixth servo motor that drives the unloading suction cup to rotate in the horizontal plane.

[0018] Furthermore, the finished product unloading mechanism includes a first unloading production line and a second unloading production line, which are connected by an angle adjustment mechanism. The end of the second unloading production line is equipped with an optical fiber for sensing.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) This invention realizes fully automated production from automatic product feeding to the power-on inspection process and then to the labeling process by setting up an upstream feeding platform, a marble initial inspection platform, an electric testing mechanism, a transfer platform, a labeling mechanism, a throwing mechanism and a finished product unloading mechanism, which greatly improves the product testing and production efficiency.

[0021] (2) The feeding arm of the present invention moves simultaneously with the upper barcode scanner and the displacement laser sensor, so that when the product is transported, the upper barcode scanner passes right by the QR code on the upper surface of the product and realizes the barcode scanning function; at the same time, when the product is transported to the marble initial inspection platform, the feeding arm drives the laser displacement sensor to pass through the four corners of the product during the reset process, and completes the detection of the product warpage, which speeds up the production cycle to a certain extent.

[0022] (3) By setting up a marble preliminary inspection platform, the present invention transports qualified products on the preliminary inspection platform to the power-on testing mechanism, and directly transports unqualified products to the throwing mechanism, thereby further accelerating the testing efficiency.

Detailed Implementation

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0044] In this embodiment, the length direction of the frame is defined as the X-axis direction, and the width direction of the frame is defined as the Y-axis direction.

[0045] The following is in conjunction with the appendix Figure 1 To be continued Figure 18 The invention is described in detail with specific embodiments.

[0046] like Figure 1-18 As shown, this invention provides a fully automatic power-on detection and label-removing device for display screens, comprising a frame 1, an upstream feeding platform 2, a marble initial inspection platform 3, a power-on detection mechanism 5, a transfer platform 6, a label-removing mechanism 7, a material throwing mechanism 8, and a finished product unloading mechanism 9, sequentially arranged on the frame 1, wherein: A feeding and handling arm 4 is provided between the upstream feeding platform 2 and the transfer platform 6. The feeding and handling arm 4 transports the display screen on the upstream feeding platform 2 to the marble preliminary inspection platform 3, and then transports the display screen that has completed the preliminary inspection on the marble preliminary inspection platform 3 to the power-on testing mechanism 5 and / or the transfer platform 6. That is, products that pass the preliminary inspection on the marble preliminary inspection platform 3 are transported to the power-on testing mechanism 5, and products that fail the preliminary inspection are transported to the transfer platform 6. A unloading and handling arm 10 is provided between the transfer platform 6 and the finished product unloading mechanism 9. The unloading and handling arm 10 transports the display screen on the transfer platform 6 to the labeling mechanism 7 or the throwing mechanism 8. That is, products that pass the inspection by the power-on testing mechanism are transported to the labeling mechanism 7 for the labeling process, and products that fail the preliminary inspection or the power-on testing are transported to the throwing mechanism 8. After the labeling mechanism 7 completes the labeling of the display screen, the unloading and handling arm 10 transports it to the finished product unloading mechanism 9. This invention achieves fully automated production from automatic product feeding to power-on testing and labeling, greatly improving product testing and production efficiency.

[0047] Specifically, such as Figure 2As shown, a feeding correction component is provided on the side of the upstream feeding platform 2. The feeding correction component includes a first push rod 21 that moves along the X direction and a second push rod 22 that moves along the Y direction. The first push rod 21 and the second push rod 22 perform initial positioning of the display screen on the upstream feeding platform 2, so as to facilitate the feeding and handling arm 4 to handle it. That is, one side of the display screen is limited and abutted by the first push rod 21, and the adjacent other side is limited and abutted by the second push rod 22. Preferably, the first push rod 21 and the second push rod 22 are both driven by cylinders. Both cylinders are mounted on the frame through cylinder mounting brackets, and the cylinder mounting brackets are located on the side of the upstream feeding platform 2.

[0048] Specifically, such as Figure 3-5 As shown, the feeding and handling arm 4 includes a feeding arm 43. The front end of the feeding arm 43 is equipped with an upper barcode scanner 44, and the rear end of the feeding arm 43 is equipped with a displacement laser sensor 45. The movement of the feeding arm 43 drives the upper barcode scanner 44 and the displacement laser sensor 45 to move, causing the displacement laser sensor 45 to move back and forth above the marble initial inspection platform 3. There are two displacement laser sensors 45, which are spaced apart at the rear end of the feeding arm 43 along the Y-axis. The two displacement laser sensors 45 are used to test the thickness of the four corners of the display screen, and then calculate the warpage of the product by the thickness of the four corners.

[0049] Specifically, the feeding and handling arm 4 includes an X-axis linear guide rail 41 and a first slider 42 sliding on the X-axis linear guide rail 41. The feeding arm 43 is fixed on the first slider 42. The feeding arm 43 is used to transport the display screen to the marble initial inspection platform 3. The feeding arm 43 includes a mounting plate 431 fixed on the first slider 42, a first cylinder 432 fixed in the middle of the mounting plate 431, and a first adsorption assembly 433 connected to the telescopic end of the first cylinder 432. The first adsorption assembly 433 moves up and down under the drive of the first cylinder 432 to adsorb the display screen. The upper barcode scanner 44 is installed at the front end of the mounting plate 431, and the displacement laser sensor 45... Installed at the rear end of the mounting plate 431, the display screen is initially positioned on the upstream feeding platform 2 and then the upper barcode scanner 44 scans and marks the product. Then, the first adsorption component 433 descends to adsorb the display screen and moves backward along the X-axis to the marble initial inspection platform 3. When the first adsorption component 433 returns to its original position to move the next display screen, the displacement laser sensor 45 passes through both ends of the display screen in sequence, and the warpage of the display screen can be calculated by measuring the thickness of the four corners.

[0050] Specifically, a Y-axis guide rail 441 extending along the Y-axis is fixed on the side of the mounting plate 431 near the starting position of the X-axis linear guide rail 41. A barcode scanner mounting plate 442 is slidably connected to the Y-axis guide rail 441 along the Y-axis. The upper barcode scanner 44 is fixedly installed at the lower end of the barcode scanner mounting plate 442, thereby realizing the position of the upper barcode scanner 44 along the Y-axis. In actual operation, the position of the upper barcode scanner 44 can be adjusted according to the position of the QR code on the product.

[0051] Specifically, two displacement laser sensors 45 are arranged side by side along the Y-axis. One displacement laser sensor is fixed to the mounting plate 431 by the first sensor mounting plate 452, and the other displacement laser sensor is mounted on the mounting plate 431 by the Y-axis moving assembly. The distance between the two displacement laser sensors is adjustable along the Y-axis and can be adjusted according to the length of the product being detected.

[0052] Specifically, the Y-axis moving assembly includes a Y-axis linear guide 454 and a second slider 451 slidably mounted on the Y-axis linear guide. A second sensor mounting plate 453 is fixed on the second slider 451, and a displacement laser sensor 45 is mounted on the second sensor mounting plate 453. By adjusting the Y-axis position of the displacement laser sensor 45 on the second sensor mounting plate 453, the distance between the two displacement laser sensors 45 can be changed to adapt to different sizes and models of products.

[0053] By mounting the loading arm 43, the barcode scanner 44, and the displacement laser sensor 45 on the same mounting plate 431, this invention enables simultaneous barcode reading and product warpage detection during the handling of the display screen. Compared to the existing separate processes, the structure of this invention accelerates the production cycle to a certain extent.

[0054] Specifically, a third slider 46 is also provided on the X-axis linear guide 41. The third slider 46 is located near the end position of the X-axis linear guide 41. A first transfer and handling arm 47 is provided on the third slider 46. The first transfer and handling arm 47 is used to transfer the product on the marble initial inspection platform 3 to the power-on testing mechanism 5. The first transfer and handling arm 47 is connected to the third slider 46 through an intermediate sliding component. The first transfer and handling arm 47 can slide along the Y-axis direction through the intermediate sliding component. The first transfer and handling arm 47 includes a connecting plate (not shown in the figure) connected to the intermediate sliding component, a second cylinder (not shown in the figure) fixed on the connecting plate, and a servo motor mounting plate connected to the telescopic end of the second cylinder. A first servo motor 471 is mounted on the servo motor mounting plate. The first servo motor 471 is connected to a flat plate suction head 472 through a reducer. The first servo motor 471 drives the flat plate suction head 472 to rotate in the horizontal plane, thereby realizing the movement of the flat plate suction head 472 in the X-axis direction, Y-axis direction, and Z-axis direction, as well as the rotation in the horizontal plane, to adjust the position of the display screen.

[0055] Specifically, a second transfer arm 48 is also fixed on the third slider 46. The second transfer arm 48 is located at the rear end of the first transfer arm 47. The second transfer arm 48 includes a third cylinder 481 and a second adsorption assembly 482 connected to the telescopic end of the third cylinder 481. The second adsorption assembly 482 is used to transport the display screen that has completed the test on the power-on detection mechanism 5 to the transfer platform 6.

[0056] The present invention has two transfer arms on the third slider 46. After the second transfer arm 48 picks up and moves the inspected product on the inspection platform a certain distance, the first transfer platform 47 transports the product that has passed the initial inspection to the inspection platform. One movement of the third slider 46 realizes the loading and unloading of a certain inspection platform, which further improves the inspection efficiency of the display screen.

[0057] Specifically, such as Figure 6As shown, the marble initial inspection platform 3 has a lower barcode scanner 31 at its front end. The lower barcode scanner 31 is slidably positioned in the Y-axis direction. Specifically, the lower barcode scanner 31 has a slide rail, slider, and handle below it to quickly adjust its position. The lower barcode scanner 31 is used to read the etched code on the lower surface of the product and upload it to the SIM system to bind with the test results. The marble initial inspection platform 3 also has a positioning camera 32 at its rear end. The positioning camera 32 takes pictures of the FPC on the display screen and positions it, and transmits the FPC's position information to the first transfer and handling arm 47. The flat suction head 472 on the first transfer and handling arm 47 moves in the X-axis, Y-axis, and Z-axis directions and rotates in the horizontal plane to finely adjust the position of the display screen, so that it is accurately placed on the inspection platform. This ensures that when different products are placed on the inspection platform, the FPC on the product can be aligned with the lower needle mold at a designated position on the inspection platform.

[0058] Specifically, the marble primary inspection platform 3 has two through holes (not shown in the figure). One through hole is equipped with a vacuum suction cup to prevent the product from being misaligned or other factors from affecting subsequent actions during movement. The other through hole is equipped with a fiber optic sensor to detect whether there is a product on the marble primary inspection platform. When no product is detected on the marble primary inspection platform 3, the information is transmitted to the feeding arm 43. The feeding arm 43 then moves to pick up the product from the upstream feeding platform 2 and transfer it to the marble primary inspection platform 3. The marble primary inspection platform 3 is equipped with a slide rail extending along the Y-axis direction at its bottom, and the marble primary inspection platform 3 is slidably connected to the slide rail.

[0059] Specifically, such as Figure 7 , Figure 8 As shown, the power-on detection mechanism 5 includes at least one detection platform 51 arranged along the X-axis direction. The detection platform 51 is arranged on a first Y-axis moving module 52. The end of the first Y-axis moving module 52 is provided with a test box 53 that matches the detection platform 51. The detection platform 51 is provided with a lower needle mold, which has multiple holes to match different models of display screens. The test box 53 is provided with an upper needle mold that cooperates with the lower needle mold. A manual slide is installed on the test box 53. The manual slide adjusts the position of the upper needle mold to match the lower needle mold, thereby realizing the power-on detection.

[0060] Specifically, such as Figure 7 , Figure 8As shown, the power-on testing mechanism 5 includes five testing platforms 51 arranged side by side along the X-axis. Five test boxes 53 are provided on opposite sides of the five testing platforms 51. All five test boxes 53 are mounted on a mounting platform 531. The mounting platform 531 is slidably connected to the frame 1 along the X-axis by a manual adjustment screw assembly 532. The manual adjustment screw assembly 532 includes a handwheel 533. During use, rotating the handwheel 533 can adjust the position of the mounting platform 531 in the X-axis direction, thereby matching the upper needle mold on the test box 53 with the lower needle mold on the testing platform 51, so as to realize the power-on testing of products of different sizes.

[0061] Specifically, such as Figure 10-16 As shown, the label-removing mechanism 7 includes a display screen transfer module 71, an easy-tear label feeding module 72, a printing module 73, and a label-removing moving module 74. The display screen transfer module 71 is used to transfer the display screen to be labeled to the label-removing station and the label-applying station; the easy-tear label feeding module 72 is used to provide easy-tear labels, which are then used to paste the old labels on the display screen; the printing module 73 is used to print new labels for labeling; the label-removing moving module 74 is used to tear off the old labels and simultaneously paste the new labels onto the display screen; the display screen transfer module 71 includes a second Y-axis moving module 711 and a module 72 disposed on the second Y-axis moving module 73. The label-peeling platform 712 on 11 has an easy-tear label feeding module 72 located on one side of the second Y-axis moving module 711. The label-peeling moving module 74 includes a gantry 741 spanning both sides of the second Y-axis moving module 711 along the X-axis direction, a first X-axis moving module 742 and a second X-axis moving module 743 respectively located on both sides of the gantry 741. A label-peeling component 75 is installed on the first X-axis moving module 742, and a label-applying component 76 is installed on the second X-axis moving module 743. The label-peeling component 75 moves along the X-axis to the easy-tear label feeding module 72 to pick up the easy-tear label, and moves to the label-peeling station to complete the removal of the old label. The label-applying component 76 moves along the X-axis to the printing module 73 to pick up the label, and moves to the label-applying station to affix the new label to the display screen.

[0062] Specifically, such as Figure 14As shown, the label-tearing assembly 75 includes a drive component 751 vertically downwardly mounted on the first X-axis moving module 742, a first mounting plate 752 connected to the drive component 751, and a clamping assembly fixed on the first mounting plate 752. The drive component 751 can drive the clamping assembly to move up and down when activated. The clamping assembly includes a second servo motor 753 fixedly mounted on the first mounting plate 752, a second mounting plate 754 fixedly connected to the output end of the second servo motor 753, and a third servo motor 755 fixedly mounted on the second mounting plate 754. The output end of the third servo motor 755 is connected to an easy-tear label clip 756. The output end of the second servo motor 753 is vertically downwardly mounted, and the second servo motor 753 drives the easy-tear label clip 756 to rotate in the horizontal plane. The output end of the third servo motor 755 is horizontally mounted and perpendicular to the first X-axis moving module 742, and the third servo motor 755 drives the easy-tear label clip 756 to rotate in the vertical direction.

[0063] Specifically, the first mounting plate 752 includes a horizontal mounting plate. A clamping component is installed on one end of the horizontal mounting plate near the easy-tear label feeding module 72, and a barcode reader 757 is fixed on the other end away from the easy-tear label feeding module 72. The barcode reader 757 is set to scan downwards. The barcode reader 757 is used to perform quality inspection on new labels. Display screens that pass the inspection are normally fed onto the OK conveyor belt (i.e., finished product feeding mechanism), and display screens that fail the inspection are fed onto the NG conveyor belt (i.e., throwing mechanism).

[0064] Specifically, such as Figure 15 As shown, a film-pressing assembly is provided on the side of the easy-tear sticker clip 756. The film-pressing assembly includes a fifth cylinder 758 disposed on the easy-tear sticker clip 756 and a film-pressing roller 759 fixedly connected to the telescopic end of the fifth cylinder 758. Driven by the fifth cylinder 758, the film-pressing roller 759 brings the easy-tear sticker close to the label to be peeled and adheres the easy-tear sticker to the old label. Then, the easy-tear sticker clip is used to pick up the easy-tear sticker adhered to the old label, and the easy-tear sticker clip is slowly moved to complete the peeling off of the old label.

[0065] Specifically, a waste box 77 is provided below the label tearing component 75. After the old label is torn off, the label tearing component 75 moves to the top of the waste box 77 under the drive of the first X-axis moving module 742. The easy-tear clip 756 rotates to the top of the waste box 44 under the drive of the second servo motor 753, and then delivers the torn old label into the waste box 77, completing the old label tearing work.

[0066] Specifically, such as Figure 16As shown, the labeling assembly 76 includes a third mounting plate 761 mounted on a second X-axis moving module 743, a fourth servo motor 762 fixed on the third mounting plate 761, and a lead screw and nut assembly 763 driven by the output end of the fourth servo motor 762. A mounting bracket 764 is fixed to the nut of the lead screw and nut assembly 763, and a fifth servo motor 765 is fixed to the mounting bracket 764. A label adsorption plate 766 is fixed to the output end of the fifth servo motor 765. The lead screw and nut assembly 763 includes a lead screw and a nut. The lead screw is driven by the output shaft of the fourth servo motor 762, causing the nut to move up and down on the lead screw, which in turn causes the label adsorption plate 766 to move up and down. To adjust the application angle of a new label, the present invention uses the fifth servo motor 765 to rotate the label adsorption plate 765, which is used to adsorb new labels, thereby achieving adjustment of the new label angle.

[0067] Specifically, such as Figure 12 , Figure 13 As shown, the printing module 73 includes a printer 731 and a label receiving assembly 732. The label receiving assembly 732 is located on the opposite side of the printing outlet of the printer 731. The label receiving assembly 732 includes a support frame, a fifth cylinder located above the support frame, and a label receiving platform fixed on the telescopic end of the fifth cylinder. The fifth cylinder drives the label receiving platform to move back and forth, so that the label receiving platform extends into the printing outlet, and the label printed by the printer is adsorbed on the label receiving platform.

[0068] Specifically, a support plate 733 is fixedly installed at the bottom of the printer 731. Two linear slide rails 734 are arranged side by side below the printer 731. The printer 731 is slidably connected to the two linear slide rails 734 via a slider fixed to the lower surface of the support plate 733. A handle 735 is fixed to the support plate 733 and is located on the back of the printer 731. When it is necessary to repair the printer or add label paper, ink, etc., the printer can be pulled out of the device using the handle, making it easier and faster to perform non-printing work. Performing non-printing work outside the device also improves the safety of the staff.

[0069] Specifically, the printer 731 has a safety door lock assembly 736 on its front side. After the printer 731 slides into position, the safety door lock assembly 736 abuts against the front end of the support plate 733, preventing the printer from continuing to slide forward and interfering with the label receiving assembly 732. The upper surface of the label receiving platform is coated with an anti-stick ceramic layer. After the label is adsorbed onto the label receiving platform, it prevents the label from sticking to the platform and being difficult to remove.

[0070] Specifically, such as Figure 13As shown, the label receiving assembly 732 also includes a first manual slide 737 mounted on a support frame and a second manual slide 738 disposed on the first manual slide 737. The label receiving platform is disposed on the second manual slide 738. The first manual slide 737 adjusts the movement of the label receiving platform in the Z-axis direction, and the second manual slide 738 adjusts the movement of the label receiving platform in the X-axis and Y-axis directions. This invention, by setting the first manual slide 737 and the second manual slide 738 on the support frame, achieves fine-tuning of the label receiving platform in the X, Y, and Z-axis directions, enabling a more precise match between the label receiving platform and the printer's printing outlet, avoiding label failure that could render the label unusable.

[0071] Specifically, such as Figure 17 As shown, the unloading and handling arm 10 includes a third X-axis moving module 101, a label-tear loading and handling arm 102 disposed at the front end of the third X-axis moving module 101, and a finished product unloading and handling arm 103 disposed at the rear end of the third X-axis moving module 101. The finished product unloading and handling arm 103 includes an unloading suction cup and a sixth servo motor 104 that drives the unloading suction cup to rotate in the horizontal plane. The sixth servo motor 104 enables the product to be placed onto the finished product unloading mechanism 9 at any angle. It should be noted that, in this embodiment, the front end and rear end refer to the... Figure 17 The front and rear ends after rotating 180°.

[0072] Specifically, such as Figure 18 As shown, the finished product unloading mechanism 9 includes a first unloading conveyor line 91 and a second unloading conveyor line 92. Conveyor belts are installed on the first unloading conveyor line 91 and the second unloading conveyor line 92. The first unloading conveyor line 91 and the second unloading conveyor line 92 are connected by an angle adjustment mechanism, which includes a pin 93 and a semi-circular arc groove 94. After adjusting the angle between the first unloading conveyor line 91 and the second unloading conveyor line 92, the two are fixed by inserting the pin 93 into the semi-circular arc groove 94. The end of the second unloading conveyor line 92 is equipped with a sensing optical fiber. When the product is not removed by the operator, the sensing optical fiber detects the product, the equipment alarms, and the finished product unloading mechanism stops operating.

[0073] The working principle of this invention is as follows: After the product flows into the upstream feeding platform 2, the feeding correction component performs initial positioning of the product. The upper barcode scanner 44 at the front end of the feeding arm 43 scans and marks the product. Then, the feeding arm 43 descends, and the first adsorption component 433 picks up the product and moves backward along the X-axis linear guide rail 41 to transport the product to the marble initial inspection platform 3. During this process, the lower barcode scanner 31 reads the etched code on the lower surface of the product and uploads it to the SIM system. After the feeding arm 43 places the product on the marble initial inspection platform 3, the displacement laser sensor 45 at the rear end of the feeding arm 43 calculates the warpage of the product by measuring the thickness of the four corners of the product. If the test result is NG, the first transfer arm 47 will move the product to the transfer platform 6, and then the unloading arm 10 will move it to the throwing mechanism, and the NG product will flow out. If the test result is OK, the first transfer arm 47 will pick up the qualified product on the marble initial inspection platform 3 and move the product to the five inspection platforms 51 in sequence. The five inspection platforms 51 will move to the five inspection stations in sequence under the drive of the five first Y-axis moving modules 52. At this time, the upper needle mold will move downward to press the product FPC interface to the lower needle mold for power-on testing. The display screen will detect the current and voltage of the product after power-on. When the test is passed, the inspection platform 51 will move to the initial position, and the second transfer arm 48 will move the product on the inspection platform 51 to the transfer platform 6. The label-removing and loading arm 102 will move the product on the transfer platform 6 to the label-removing and labeling platform 712 for label removal and labeling. Finally, the finished product unloading arm 103 will move the finished product to the first unloading assembly line 91, waiting for manual removal.

[0074] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the nature and scope of the present invention. Various modifications made to the above embodiments by those skilled in the art after reading this specification are all within the scope of protection of the present invention.
