[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 6This utility model provides a screen conveyor line, which includes: a frame 1, an upper guide rail 2 and a lower guide rail 3 mounted on the top of the frame 1, a transmission chain 4 mounted on the frame 1, and a servo motor 5 for driving the transmission chain 4 to move along the direction of the upper guide rail 2. A CNC box 11 for controlling the start of the servo motor 5 is also mounted on the frame 1; and several suspended trolleys 6, which are slidably mounted on the upper guide rail 2 and the lower guide rail 3 at equal intervals and are connected to the transmission chain 4. Suspension arms 7 are fixedly installed on the outer side of the screen. A damping sleeve 71 is embedded in the suspension arm 7. A connecting arm 72 is rotatably installed inside the damping sleeve 71. A clamping mechanism 8 for clamping the screen is installed at the bottom end of the connecting arm 72. The clamping mechanism 8 includes a crossbeam 81, which is fixedly installed at the bottom end of the connecting arm 72. A T-slot 801 is opened in the crossbeam 81. A bidirectional threaded rod 82 is rotatably installed in the T-slot 801. A telescopic and adjustable clamping arm 83 is symmetrically threaded on the bidirectional threaded rod 82. A clamping assembly 84 is installed on the clamping arm 83.

[0027] The clamping arm 83 includes a connecting plate 831, which is slidably installed in a T-slot 801. One end of the connecting plate 831 is fixedly installed with a transmission plate 8311 that is threadedly connected to the bidirectional threaded rod 82. The other end of the connecting plate 831 is installed with a fixing sleeve 832. A movable rod 833 is slidably installed inside the fixing sleeve 832. A lower support plate 834 is fixedly installed at the bottom end of the movable rod 833. The lower support plate 834 has a lower groove 803 for placing the screen. A rear support plate 835 is fixedly installed at the top end of the lower support plate 834 behind the lower groove 803. The front side wall of the fixing sleeve 832 has a T-slot 804 for installing the clamping assembly 84.

[0028] The movable rod 833 has several evenly spaced limiting holes 802, and a pin 8321 that engages with the limiting holes 802 is threaded onto one side of the fixed sleeve 832.

[0029] It should be noted that during use, the servo motor 5 is intermittently started by the CNC box 11, which drives the transmission chain 4 to drive several suspended carriages 6 to move and transport intermittently along the upper guide rail 2 (the interval time is adapted to the working time of each inspection station). The screen is clamped from one corner of the frame 1 by the clamping mechanism 8, and then transported forward with the suspended carriages 6 to the inspection station for inspection (such as image testing: displaying pure white, pure black, red, green, blue and other pure color images, as well as checkerboard, grayscale and other test images, to find bright spots, dark spots, foreign objects, line defects, etc.). When the clamping mechanism 8 clamps the screen, it drives the two clamps by turning the bidirectional threaded rod 82. The spacing of the holding arm 83 is adjusted (when the bidirectional threaded rod 82 rotates, the connecting plate 831 is driven by the transmission plate 8311 to slide in the T-slot 801 to achieve adjustment) to match the width of the screen. Then, the movable rod 833 of the clamping arm 83 is pulled so that the length of the lower support plate 834 extending along the fixed sleeve 832 matches the width of the screen. After extension, the pin 8321 is inserted into the corresponding limiting hole 802 to complete the limiting fixation. Then, the screen is placed in the lower groove 803 opened in the lower support plate 834. After placement, the clamping assembly 84 is used for quick pressing to fix the screen on the clamping mechanism 8, so that the screen can be quickly installed on the conveyor line for conveying and testing.

[0030] It should also be noted that the interval time here can be programmed through the CNC box 11 to control the periodic start and stop of the servo motor 5, thereby realizing the intermittent operation of the drive transmission chain 4, thus controlling the conveyor line to operate intermittently, which facilitates the installation and testing of the screen.

[0031] Furthermore, in order to improve the protection of the screen and avoid pinching and bumping, a sponge pad 836 is embedded in the lower recess 803 to provide protection for the screen frame inside the lower recess 803.

[0032] In this embodiment, a knob 821 is fixedly sleeved in the middle of the bidirectional threaded rod 82. The outer wall of the knob 821 is provided with anti-slip texture, which makes it easy to drive the bidirectional threaded rod 82 to rotate using the knob 821 to adjust the distance between the two clamping arms 83.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 6 The clamping assembly 84 includes a slider 843, which is slidably installed in the T-slot 804. A lead screw 841 is rotatably installed on the front side wall of the fixed sleeve 832. One end of the slider 843 extending out of the T-slot 804 has a threaded hole for threaded connection of the lead screw 841. A handwheel 842 is fixedly sleeved on the top of the lead screw 841. A clamping corner block 844 is fixedly installed on the slider 843. A right-angle groove 805 for pressing the top corner of the screen is opened on the clamping corner block 844. A rubber pad 845 is pasted in the right-angle groove 805.

[0034] It should be noted that when using the clamping assembly 84, after the screen is clamped in the lower groove 803 of the lower support plate 834, the handwheel 842 is turned to drive the lead screw 841 to rotate. The rotation of the lead screw 841 drives the slider 843 to slide along the T-slot 804 until the right-angle groove 805 of the clamping corner block 844 is clamped at the top corner of the screen, thus achieving the clamping of the screen. When the screen needs to be removed, simply reverse the handwheel 842.

[0035] In the embodiments of this utility model, please refer to Figures 1 to 2 Several plug-in strips 9 are installed at equal intervals on the outer side wall of the lower guide rail 3, and the plug-in strips 9 are electrically connected to the CNC box 11.

[0036] It should be noted that this allows the power strip 9 to be used to connect the screen to power when the screen needs to be tested.

[0037] The working principle of the screen conveyor line provided by this utility model is as follows:

[0038] In use, the servo motor 5 is intermittently started by the CNC box 11, which drives the transmission chain 4 to drive several suspended trolleys 6 to move intermittently along the upper guide rail 2. The screen is clamped by the clamping mechanism 8 from one corner of the frame 1, and then transported forward with the suspended trolleys 6 to the inspection station for inspection. When the clamping mechanism 8 clamps the screen, the two clamping arms 83 are adjusted by turning the bidirectional threaded rod 82 (when the bidirectional threaded rod 82 rotates, the connecting plate 831 is driven by the transmission plate 8311 to slide in the T-slot 801 to achieve adjustment) to adapt to the width of the screen. Pull the movable rod 833 of the clamping arm 83 so that the length of the lower support plate 834 extending along the fixed sleeve 832 matches the width of the screen. After extending, insert the pin 8321 into the corresponding limiting hole 802 to complete the limiting fixation. Then place the screen in the lower groove 803 opened in the lower support plate 834. After placement, turn the handwheel 842 to drive the lead screw 841 to rotate. The rotation of the lead screw 841 drives the slider 843 to slide along the T-slot 804 until it drives the right angle groove 805 of the clamping block 844 to lock into the top corner of the screen, realizing the clamping of the screen and realizing the screen to be quickly installed on the conveyor line for conveying and testing.

[0039] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
