[0028] The loader 1 includes a product support seat 11, a first conveyor belt 12, a lifting push plate 13, a first vacuum suction plate 14, a flipping upper plate mechanism 15, and an image integration platform. The product support seat 11 is two parallel inclined plates, one end of which is provided with an inclined support plate 111 for supporting the obliquely rotating circuit board. The first conveyor belt 12 is two parallel conveyor belts, and the product support seat 11 is arranged on the first conveyor belt 12. The first vacuum suction plate 14 is arranged above the rear end of the conveying direction of the first conveyor belt 12. The first vacuum suction plate 14 is directly opposite to the bottom of the support plate 111 and the side away from the support plate 111 is provided with a first telescopic device 141, so that the first vacuum suction plate 14 can adsorb the bottom end of the circuit board on the product support seat 11. The first telescopic device 141 is preferably a telescopic cylinder. The lifting push plate 13 is arranged between the support plate 111 and the first vacuum suction plate 14 and can be retracted to the bottom of the first conveyor belt 12 to avoid affecting the movement of the product supporting seat; the lifting push plate 13 can be pushed by a telescopic cylinder, and after it is raised, it can push open the top of the circuit board and cooperate with the first vacuum suction plate 14 to complete the single board feeding.

[0029] like Figure 3 As shown, the flipping upper plate mechanism 15 includes a second telescopic device 151, a rotating crank 152, a flipping shaft 153, and a flap support rod 154. The flipping shaft 153 is rotatably connected to the top of the first conveyor belt 12 and one end of the flipping shaft 153 is connected to the second telescopic device 151 through the rotating crank 152.

In this way, after the first vacuum suction plate 14 absorbs the circuit board, the bottom end of the circuit board can be placed on the buckle 155 after contraction. At this time, the lifting and pushing plate 13 and the second telescopic device 151 act simultaneously, and the circuit board can be flipped 90 degrees.

The first platen 161 is provided with a second conveyor belt 165 and a recess 1611 located on one side of the second conveyor belt 165. When the flipping plate support rod 154 is flipped to a horizontal plane, it is supported on the recess 1611.

The automatic clamping plate structure 162 is arranged in both the length and width directions of the first platen 161 to clamp and position the electrical board. The first three-axis rotating platform 163 is arranged below the first platen 161, and the first alignment camera 164 is arranged on the left and right sides of the first three-axis rotating platform 163.

[0032] Due to the size and application requirements of the smart large screen driver circuit board, the following aspects need to be paid attention to during the production of long circuit boards:

[0033] Material selection and stability: Extra-long circuit boards usually require special high-strength, low-warping materials to ensure stability and reliability during long-term use. Material selection and supplier stability are critical to production.

[0034] Interlayer alignment and interlayer connection: Since the board is long and thin, the alignment accuracy between layers is very high to ensure signal integrity and reliability. The process control of interlayer connection is also a major challenge.

[0035] Processing accuracy: The length of the ultra-long circuit board is much longer than that of the conventional circuit board, which requires the processing equipment to have higher accuracy and stability to ensure the accuracy of the circuits and holes on the board.

[0036] Thermal management and warpage control: Ultra-long circuit boards may encounter uneven heat distribution during operation, requiring special thermal management measures. At the same time, warpage control is also an issue that requires special attention during production.

[0037] Automation and logistics: The production of ultra-long circuit boards usually requires highly automated equipment and efficient logistics systems to ensure production efficiency and product quality.

[0038] Testing and quality control: Due to the irregular shape and special application requirements of extra-long circuit boards, the testing and quality control process needs to be more sophisticated and comprehensive to ensure that each board meets strict quality standards.

[0039] Environmental control: Environmental conditions such as temperature, humidity, cleanliness, etc. need to be strictly controlled during the production process of ultra-long circuit boards to prevent pollution and improve product reliability.

[0040] The utility model utilizes high-precision alignment technology. A slanted support plate is arranged on the circuit board, so that the circuit board can be placed slantly on the product supporting seat and transported by the first conveyor belt. The first vacuum suction plate absorbs the bottom of the circuit board and shrinks, and the bottom end of the circuit board is placed on the catch of the flipping upper plate mechanism. Then the lifting and pushing plate rises to push open the top of the circuit board, and at the same time the flip axis flips the circuit board 90 degrees onto the image integration platform. The operation of the slanted feeding and automatic flipping plate can effectively avoid scratches or indentations on the circuit board, effectively improving the feeding efficiency. At the same time, the smart large-screen driver circuit board is defectively detected after each step of printing and brushing, and the defective smart large-screen driver circuit boards are picked out and excluded to avoid subsequent processes, thereby improving the effect and efficiency of the overall process. At the same time, it is avoided that the defective smart large-screen driver circuit board is subjected to subsequent operations, thereby improving the work effect and efficiency, increasing safety, and facilitating the use of the device.

[0041] The image integration platform is equipped with a first alignment camera, which can accurately identify the position of the circuit board. Together with the first three-axis rotating platform, it can automatically align and correct the required accuracy for printing, greatly improving the quality of printing. The screen printer is equipped with a three-axis rotating displacement platform and a second alignment camera, which integrates automatic alignment and displacement, and can improve the accuracy and versatility of printing. The set feeder can automatically complete operations such as feeding, framing and changing frames, saving time and labor.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
