Detailed Implementation

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] An automated assembly device for a display screen based on machine vision includes a frame 1, a first product loading assembly 2 mounted on the frame 1, and a second product loading assembly 3 mounted on the frame 1. The second product loading assembly 3 is used to load a second product, and the first product loading assembly 2 is used to load a first product and assemble the first product with the second product. The first product is a liquid crystal display (LCD) screen, and the second product is a backlight module of the display screen.

[0020] The first product feeding assembly includes a conveyor table 201 mounted on a frame 1. A first conveyor belt 202 is mounted on the conveyor table 201, and the first conveyor belt 202 is used to convey the first product along a first direction. A guide plate 203 and a pusher block 204 are mounted on the conveyor table 201 at the output end of the first conveyor belt 202. The guide plate 203 and the pusher block 204 are respectively located on both sides of the first conveyor belt 202 along a second direction, which is perpendicular to the first direction. The pusher block 204 can move back and forth along the second direction to push the first product towards and against the guide plate 203, thereby positioning the first product. A stop block 2011 is also mounted at the output end of the first conveyor belt 202. The stop block 2011 is used to block the first product and also positions the first product in the first direction.

[0021] The first product feeding assembly also includes a first tearing assembly 207 mounted on the frame 1. A first protective film is provided on the first product to protect the surface of the LCD screen. The first protective film needs to be removed before installation. The first tearing assembly 207 includes a mounting frame 2074 mounted on the frame 1 and a tape roller 2071, a waste roller 2072, and a peeling plate 2073 mounted on the mounting frame 2074. The tape roller 2071 is used to hold the tape for tearing. The peeling plate 2073 is horizontally mounted on the mounting frame 2074. The first product to be peeled is placed on the peeling plate 2073. The tape coming out of the tape roller 2071 passes over the upper surface of the peeling plate 2073 with the sticky side of the tape facing upwards to stick to the first product. The tape can move the first product as it moves. A peeling surface 2075 is provided at one end of the peeling plate 2073 near the second product feeding assembly 3. The peeling surface 2075 is located on the lower surface of the peeling plate 2073 and gradually slopes upward along the direction near the second product feeding assembly 3. After passing through the peeling plate 2073, the tape is wound around the waste roller 2072. The waste roller 2072 is located between the tape roller 2071 and the second product feeding assembly 3. The peeling plate 2073 can move back and forth along the second direction. Within the movement range of the peeling plate 2073, the end of the peeling plate 2073 near the second product feeding assembly 3 is always closer to the second product feeding assembly 3 than the waste roller 2072, ensuring that the tape moves in the opposite direction after passing through the peeling plate 2073, thus achieving peeling.

[0022] The first product loading assembly 2 further includes a first suction cup 205, which is movable between the first conveyor belt 202 and the peeling plate 2073 to move the first product on the first conveyor belt 202 onto the peeling plate 2073. The first suction cup 205 is rotatable along a vertical axis to adjust the angle of the first product on the peeling plate 2073. Preferably, when the first product is placed on the peeling plate 2073, one corner is positioned closer to the second product loading assembly 3 than the other positions of the first product. During peeling, peeling is performed on one corner first, making it easier to peel off the first protective film.

[0023] Preferably, a cable suction nozzle 206 is provided on one side of the first suction cup 205 for adsorbing the cable on the LCD screen, and the cable suction nozzle 206 moves synchronously with the first suction cup 205.

[0024] When the first product needs to be moved to the peeling plate 2073, the peeling plate 2073 is first moved to the side close to the first conveyor belt 202. The first suction cup 205 and the cable suction nozzle 206 move the first product onto the peeling plate 2073. Since the adhesive side of the tape is facing upwards, when the first product is placed on the peeling plate 2073, the tape will stick to the first protective film of the first product. Then the peeling plate 2073 carries the first product a certain distance toward the second product feeding assembly 3.

[0025] Preferably, a strip groove 2074 extending along a second direction is further provided on the peeling plate 2073, the strip groove 2074 being located on the path of the tape passing through the peeling plate 2073. A top roller 208 is provided below the peeling plate 2073, the top roller 208 being capable of moving up and down and moving back and forth along the second direction. When the top roller 208 moves up and down, it can pass through the strip groove 2074, and at least its highest point can be higher than the upper surface of the peeling plate 2073. Thus, when the first suction cup 205 moves the first product onto the peeling plate 2073, the first suction cup 205 presses the first product downwards onto the peeling plate 2073, the top roller 208 moves upwards a predetermined distance, pushes against the tape, and moves a certain distance along the strip groove 2074, making the tape adhere tightly to the first protective film. After adhesion, the first suction cup 205 and the cable nozzle 206 release the first product, and the top roller 208 moves downwards and returns to its original position.

[0026] The first product loading assembly 2 also includes a robotic arm 210 mounted on the frame 1 and a second suction cup 209 mounted on the free end of the robotic arm 210. The robotic arm 210 can move the LCD screen after the first protective film has been removed onto the second product loading assembly 3 via the second suction cup 209. When the first suction cup 205 detaches from the first product, the robotic arm 210 moves the second suction cup 209 to the position of the first product to hold it. Then, the peeling plate 2073 moves away from the second product loading assembly 3, and the waste roller 2072 tightens the tape at a predetermined speed. As the peeling plate 2073 moves, the tape tears the first protective film off the LCD screen at the peeling surface 2075.

[0027] The second product feeding assembly 3 is used to convey the second product along a third direction. The second product feeding assembly 3 is sequentially arranged along the third direction as follows: an infeed platform 301, a tearing platform 302, a transfer platform 303, an assembly platform 304, and an unloading platform 305. The infeed platform 301 is used to convey the second product along the third direction. Two sets of positioning blocks 3011 are arranged near the output end of the infeed platform 301. The two sets of positioning blocks 3011 are arranged opposite each other along the second direction and can move towards each other, used to push the second product against each other from both sides along the second direction to position the second product in the second direction. A stop bar 3012 is also provided at the output end of the infeed platform 301. The stop bar 3012 is located on the path of the second product moving along the third direction and is used to prevent the second product from moving further after it has reached its position in the third direction. The positioning of the second product can be achieved through the two sets of positioning blocks 3011 and the stop bar 3012.

[0028] The second product feeding assembly 3 also includes a transfer assembly 306. The transfer assembly 306 includes a movable plate 3062 mounted on the frame 1 and four sets of first suction nozzles 3061 mounted on the movable plate 3062. The movable plate 3062 extends along a third direction, and the four sets of first suction nozzles 3061 are evenly spaced along the third direction on the movable plate 3062. The first suction nozzles 3061 are used to hold the second product. The movable plate 3062 can move up and down and back and forth along the third direction. When it is necessary to move the second product downstream, the four sets of first suction nozzles 3061 are respectively located at the corresponding feeding platform 301, tearing platform 302, transfer platform 303, and mounting platform 304. Then they move upward to hold the second product at the corresponding position and continue to move to a predetermined height. Then the movable plate 3062 moves along the third direction to move the second product at each position to the next position.

[0029] The tearing table 302 includes two first support plates 3021 mounted on the frame 1. The two first support plates 3021 are arranged along a second direction and are spaced apart. Each support plate 3021 is provided with multiple clearance slots 3022, which are equally spaced along a third direction and extend along the second direction. The tearing table 302 also includes two sets of clamping rods 3023. Each set of clamping rods 3023 has two clamping rods, and each set of clamping rods 3023 corresponds to one support plate 3021. The two clamping rods 2023 in each set extend upward from the two clearance slots 3022 on the same support plate 3021 to a certain height and can move back and forth along the second direction, thereby clamping the second product located on the support plate 3021.

[0030] The second feeding assembly 3 also includes a gripper 307 positioned on the frame 1 corresponding to the tearing table 302. A second protective film is affixed to the surface of the second product, with the edge of the second protective film extending from the second product. The gripper 307 is used to clamp the edge of the second protective film and tear it off the second product. Specifically, the second feeding assembly 3 also includes an XYZ module, with a first lifting plate 308 positioned on the output end of the XYZ module. The gripper 308 is movably mounted on the first lifting plate 308 via a second lifting plate 309. A spring 310 is positioned between the first lifting plate 308 and the second lifting plate 309. The spring 310 is vertically positioned, with its upper end abutting against the first lifting plate 308 and its lower end abutting against the second lifting plate 309. The spring 310 is always compressed, and when the gripper 307 moves downward and collides with the first support plate 3021, the spring 310 provides a certain buffering effect.

[0031] After the second protective film is removed, the transfer assembly 306 moves the removed second product onto the transfer platform 303. The transfer platform 303 includes two sets of second support plates 3031, arranged along a second direction with a certain interval. Each set of second support plates 3031 contains two second support plates 3031, with a certain interval between the two second support plates 3013 in a third direction. A second suction nozzle 3032 is provided between the two second support plates 3013 in each set, used to hold the second product.

[0032] The mounting platform 304 includes two sets of third support plates 3041 mounted on the frame 1. The two sets of third support plates 3041 are spaced apart along a second direction, and each set has two third support plates 3041. The two third support plates 3041 in each set are spaced apart along a third direction. A third suction nozzle 3042 is disposed between the two third support plates 3041, and the third suction nozzle 3042 is used to hold the second product. On the set of third support plates 3041 away from the first product feeding component 1, a light source 3043 is embedded in each of the two third support plates 3041. A camera 3044 is disposed directly above each of the two light sources 3043. When the second product moves onto the third support plate 3041, the third suction nozzle 3042 can hold the second product, the light source 3043 is turned on, and the camera 3044 takes a picture of the second product to obtain the accurate position of the second product.

[0033] Once the precise position of the second product is obtained, the robotic arm moves the first product onto the second product, assembling the first and second products. After assembly, the moving component 306 moves the assembled product onto the unloading platform 305.

Step 17: The robotic arm drives the second suction cup to pick up the first product; Step 18: The peeling plate moves away from the second product feeding assembly, and the waste roller tightens the tape at a predetermined speed until the first protective film is peeled off. Step 19: The robotic arm moves the first product to the second product loading assembly; Step 2: Load the second product, which includes the following steps: Step 21: Place the second product onto the feeding platform; Step 22: When the second product abuts against the stop bar, the two sets of positioning blocks move towards each other to position the second product. Step 23: The material transfer assembly moves the second product from the feeding platform to the tearing platform; Step 24: The clamping bar holds the second product on the tearing table; Step 25: Clamp the edge of the second protective film with the grippers and peel the second protective film off the second product; Step 26: The transfer assembly moves the second product to the transfer table; Step 27: The transfer assembly moves the second product to the assembly table; Step 28: The camera takes a picture of the second product, and the accurate location of the second product is obtained based on the captured image; Step 29: The robotic arm places the first product onto the second product; Step 210: The material transfer assembly moves the assembled first and second products to the unloading platform.
