The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] The circuit board manufacturing process involves operations such as board separation and testing. After separation and testing, all circuit boards need to be classified and sorted according to the test results for subsequent shipment. Currently, the classification of circuit boards is mainly done manually, removing defective products and sorting all good products for shipment. This traditional method has low efficiency in classification and sorting, which is not conducive to improving production efficiency.

[0020] To address this, this utility model provides a circuit board sorting and unloading machine. An image recognition device distinguishes between good and defective circuit boards, identifying their positions and angles. A multi-axis rotating robotic arm then grips the good circuit boards based on their positions and angles, adjusting the gripping angle to place them onto a first unloading mechanism. This first unloading mechanism then transfers the circuit boards to a first unloading conveyor belt. A pushing device pushes defective circuit boards to a receiving platform, achieving separate collection of good and defective products, thereby improving the efficiency of circuit board sorting and organization.

[0021] The circuit board sorting and cutting machine of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown in the figure, this utility model embodiment proposes a circuit board sorting and cutting machine, including: The transmission platform 100 is equipped with an image recognition device (not shown) and a liftable multi-axis rotating robot arm on its upper part. The first feeding mechanism 300 is located on one side of the transmission platform 100. The first feeding mechanism 300 includes a first feeding table 310 and a second feeding table 320 that are spaced apart. The first unloading conveyor belt 500 is located below the first unloading mechanism 300. The first unloading platform 310 includes a plurality of first unloading plates arranged at intervals. The second unloading platform 320 includes a plurality of second unloading plates arranged at intervals. The first unloading conveyor belt 500 includes a plurality of first unloading rollers arranged at intervals. The first unloading rollers are staggered with the first unloading plates and the second unloading plates, respectively. Both the first unloading platform 310 and the second unloading platform 320 are capable of lifting and lowering. The blocking device 1000 is located at the exit of the transmission platform 100; The pushing device 800 is located at the front end of the blocking device 900; The receiving platform 900 is located on one side of the transmission platform 100, and the pushing direction of the pushing device 800 is towards the receiving platform 900.

[0023] It should be noted that the circuit board sorting and unloading machine is connected to the inspection mechanism. After the inspection mechanism completes the inspection of the circuit boards 700, it sends the circuit boards 700 to the transmission platform 100. For defective products that fail the inspection, markings are set on the defective products using methods such as laser marking to facilitate identification by the image recognition device. When the inspection mechanism sends the circuit boards 700 to the transmission platform 100, the circuit boards 700 are arranged in multiple rows and columns. During the transmission process, the angle of the circuit boards 700 may shift to a certain extent, and the angle needs to be corrected afterward to ensure that the circuit boards 700 are stacked neatly. When the transmission platform 100 moves the circuit boards 700, it uses the image recognition device to identify whether each circuit board 700 is a good or defective product, and identifies the corresponding position and angle of each circuit board 700. Then, a multi-axis rotating robotic arm picks up each circuit board 700 and places it into the first unloading mechanism 300. It should be noted that after the multi-axis rotary robot grips the circuit board 700, it will rotate by a corresponding angle according to the offset angle of the circuit board 700, thereby correcting the angle of the circuit board 700. When the multi-axis rotary robot grips the circuit board 700 to the first feeding mechanism 300, it will first place the circuit board 700 on the first feeding table 310. At the same time, for each circuit board 700 placed, the first feeding table 310 will descend by a height (this height is consistent with the thickness of the circuit board 700). When the first feeding table 310 is full of circuit boards 700, the surface of the first feeding plate of the first feeding table 310 will descend to below the first feeding roller of the first feeding conveyor belt 500. The circuit boards 700 on the first feeding table 310 can no longer descend and will remain on the first feeding conveyor belt 500, so that the first feeding conveyor belt 500 will transport the circuit boards 700 to the unloading point. When the first feeding platform 310 is full of circuit boards 700, the multi-axis rotating robot will place the gripped circuit boards 700 onto the second feeding platform 320. Similarly, the second feeding platform 320 descends one height each time a circuit board 700 is placed. When the second feeding platform 320 is full of circuit boards 700, the surface of the second feeding plate of the second feeding platform 320 descends to below the first feeding roller of the first unloading conveyor belt 500. The circuit boards 700 on the second feeding platform 320 can no longer descend and will remain on the first unloading conveyor belt 500, thus allowing the first unloading conveyor belt 500 to transport the circuit boards 700 to the unloading point. When the second feeding platform 320 is full of circuit boards 700, the multi-axis rotating robot will place the gripped circuit boards 700 onto the first feeding platform 310. That is, the first feeding platform 310 and the second feeding platform 320 will switch alternately.

[0024] For defective circuit boards, the multi-axis rotating robot will not grab them, allowing the defective circuit boards to continue moving with the transfer platform 100. When the defective circuit board moves to the blocking device 1000, the blocking device 1000 will stop the circuit board 700 from moving forward. At the same time, the pushing device 800 will push the defective circuit board onto the receiving platform 900, completing the collection of the defective circuit board.

[0025] According to the circuit board sorting and unloading machine of this application embodiment, the image recognition device distinguishes whether the circuit board 700 belongs to good or defective products, and identifies the position and angle of each circuit board 700. Then, the multi-axis rotating robot grabs each good circuit board according to its position and angle, and adjusts the angle of the grabbed circuit board 700 to pick up the circuit board 700 to the first unloading mechanism 300. The first unloading mechanism 300 then transfers the circuit board 700 to the first unloading conveyor belt 500. At the same time, the pushing device 800 pushes the defective products to the receiving platform 900, realizing the separate collection of good and defective products, thereby improving the sorting and sorting efficiency of circuit boards.

[0026] Furthermore, according to some embodiments of the present invention, such as Figure 1 As shown, the circuit board sorting and cutting machine also includes: The second feeding mechanism 400 is located on the other side of the transmission platform 100. The second feeding mechanism 400 includes a third feeding platform 410 and a fourth feeding platform 420 that are spaced apart. The second feeding conveyor belt 600 is located below the second feeding mechanism 400. The third feeding platform 410 includes a plurality of third feeding plates arranged at intervals. The fourth feeding platform 420 includes a plurality of fourth feeding plates arranged at intervals. The second feeding conveyor belt 600 includes a plurality of second feeding rollers arranged at intervals. The second feeding rollers are staggered with the third feeding plates and the fourth feeding plates, respectively. The third feeding platform 410 and the fourth feeding platform 420 can both be lifted and lowered.

[0027] Specifically, such as Figure 1As shown, the first feeding mechanism 300 and the second feeding mechanism 400 are located on the left and right sides of the transmission platform 100, respectively. The multi-axis rotating robot can choose to place the good circuit board on the first feeding mechanism 300 or the second feeding mechanism 400 depending on whether the good circuit board is closer to the first feeding mechanism 300 or the second feeding mechanism 400, thereby saving the moving distance and moving time of the multi-axis rotating robot and improving the gripping efficiency of the circuit board 700. It should be noted that when the multi-axis rotating robot grabs the circuit board 700 to the second feeding mechanism 400, it will place the circuit board 700 on the third feeding platform 410. At the same time, the third feeding platform 410 will descend one height for each circuit board 700 placed. When the third feeding platform 410 is full of circuit boards 700, the surface of the third feeding plate of the third feeding platform 410 will descend to below the second feeding roller of the second feeding conveyor belt 600. The circuit boards 700 on the third feeding platform can no longer descend and will remain on the second feeding conveyor belt 600, so that the second feeding conveyor belt 600 will transport the circuit boards 700 to the unloading point. When the third feeding platform 410 is full of circuit boards 700, the multi-axis rotary robot will place the gripped circuit boards 700 onto the fourth feeding platform 420. Similarly, the fourth feeding platform 420 descends one height each time a circuit board 700 is placed. When the fourth feeding platform 420 is full of circuit boards 700, the surface of the fourth feeding plate of the fourth feeding platform 420 descends to below the second feeding roller of the second feeding conveyor belt 600. The circuit boards 700 on the fourth feeding platform can no longer descend and will remain on the second feeding conveyor belt 600, thus allowing the second feeding conveyor belt 600 to transport the circuit boards 700 to the unloading point. When the fourth feeding platform is full of circuit boards 700, the multi-axis rotary robot will place the gripped circuit boards 700 onto the third feeding platform. That is, the third and fourth feeding platforms will be switched alternately.

[0028] According to the circuit board sorting and unloading machine of this application embodiment, the position and angle of each circuit board 700 are identified by an image recognition device, and the circuit boards 700 are distinguished as good products and defective products. Then, a multi-axis rotating robot arm grabs each good circuit board 700 according to the position and angle of each good product, and adjusts the angle of the grabbed circuit board 700 to select to grab the circuit board 700 to the first unloading mechanism 300 or the second unloading mechanism 400. At the same time, the first unloading mechanism 300 is provided with a first unloading table 310 and a second unloading table 320, and the second unloading mechanism 400 is provided with a third unloading table 410 and a fourth unloading table 420. The circuit boards 700 can be placed on the first unloading table 310 and the second unloading table 320 in turn, and on the third unloading table 410 and the fourth unloading table 420 in turn, thereby improving the sorting and grabbing efficiency of the circuit boards 700.

[0029] Furthermore, in some embodiments of this application, such as Figure 1 As shown, the transmission platform 100 is divided into a first region 110 and a second region 120 in a first direction. The first region 110 is close to the first feeding mechanism 300, and the second region 120 is close to the second feeding mechanism 400. The first direction is perpendicular to the transmission direction of the transmission platform 100. There are two multi-axis rotating robots, namely a first multi-axis rotating robot 210 and a second multi-axis rotating robot 220. The first multi-axis rotating robot 210 corresponds to the first region 110, and the second multi-axis rotating robot 220 corresponds to the second region 120. The first multi-axis rotating robot 210 and the second multi-axis rotating robot 220 are arranged at intervals along the transmission direction of the transmission platform 100. It should be noted that the transmission direction of the transmission platform 100 is from front to back, and the first direction is left and right. By dividing the transmission platform 100 into a first area 110 and a second area 120, the first multi-axis rotating robot 210 is responsible for grasping the circuit board 700 located in the first area 110, and the second multi-axis rotating robot 220 is responsible for grasping the circuit board 700 located in the second area 120, thereby improving the grasping efficiency of the first multi-axis rotating robot 210 and the second multi-axis rotating robot 220. For circuit boards 700 that are partially located in the first area 110 and partially located in the second area 120, the size of the circuit board 700 in the first area 110 and the size in the second area 120 are identified by an image recognition device. If the size of the circuit board 700 in the first area 110 is larger than the size in the second area 120, the first multi-axis rotating robot 210 grasps the circuit board 700 to the first unloading mechanism 300; otherwise, the second multi-axis rotating robot 220 grasps the circuit board 700 to the second unloading mechanism 400. At the same time, such as Figure 1 As shown, the first multi-axis rotary robot 210 is located at the front right of the transfer platform 100, close to the first unloading mechanism 300; the second multi-axis rotary robot 220 is located at the rear left of the transfer platform 200, close to the second unloading mechanism 400. When the circuit board 700 enters the transfer platform 100, it first passes through the first multi-axis rotary robot 210, which places the circuit board 700 in the first area 110 of the current row onto the first unloading mechanism 300. Meanwhile, the circuit board 700 in the second area 120 of the current row continues to move forward with the transfer platform 100 until it reaches below the second multi-axis rotary robot 220, where the second multi-axis rotary robot 220 picks up the circuit board 700 and places it onto the second unloading mechanism 400. By staggering the first multi-axis rotary robot 210 and the second multi-axis rotary robot 220 in front-back and left-right directions, they do not interfere with each other and the picking efficiency of the circuit board 700 is improved.

[0030] When circuit board 700 is defective, neither the first multi-axis rotary robot 210 nor the second multi-axis rotary robot 220 will grasp it as it passes the transfer platform 100. The circuit board 700 continues to move with the transfer platform 100 to the blocking device 1000. In this example, the blocking device 1000 uses a blocking plate to prevent the defective circuit board from continuing to move with the transfer platform 100. Simultaneously, the pushing device 800 pushes the circuit board 700 to the receiving platform 900, thereby collecting all defective products. It should be noted that in this example, the pushing device 800 includes a slide rail 810, a pushing plate 820 disposed on the slide rail 810, and a driver that drives the pushing plate 820 to move along the slide rail 810. When the driver drives the pushing plate 820 to move along the slide rail from left to right, it can push the circuit board 700 into the receiving platform 900.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
