DETAILED DESCRIPTION

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0019] Example 1

[0020] A flexible circuit board anti-deviation positioning patch device, such as Figures 1-4 As shown, the device includes a worktable 1, support base 2, transmission component 3, slide table 4, cylinder 5, transfer table 51, placement head 6, control module 61, detection module 62, transmission component 2 7, slide table 2 8, unloading table 9, and vacuum suction hole 910. The worktable 1 serves as the foundation of the entire device, stably supporting all components and ensuring that all operations are performed in a stable working environment. The worktable 1 is made of marble, which not only has extremely high flatness and stability but also excellent resistance to deformation, ensuring that the entire device maintains high precision during long-term operation. Support bases 2 are provided on the left and right sides of the rear of the worktable 1. Transmission component 3 is horizontally positioned between the upper parts of these two support bases 2. Transmission component 3 ensures that slide table 4 can move smoothly left and right on it through a precise mechanical structure, thereby providing a precise horizontal movement path for the placement head 6.

[0021] like Figure 2 As shown, a cylinder 5 is fixedly installed on the front side of the slide table 4. The end of the movable rod of the cylinder 5 is equipped with a placement head 6. The extension and retraction of the cylinder 5 drives the placement head 6 to move up and down. This design allows the placement head 6 to flexibly adjust its height in the vertical direction. The upper part of the placement head 6 integrates a control module 61, which is responsible for receiving instructions and controlling the precise movement of the placement head to ensure that each action conforms to the preset parameters, thereby improving placement accuracy and efficiency. At the same time, the placement head 6 is also equipped with a material picking module and a vision module. The material picking module is used to pick up and place components, while the vision module assists in the positioning and identification of components to ensure that the components have been correctly identified and aligned before placement.

[0022] A transfer platform 51 is provided on one side of the top of the workbench 1. At the same time, a transmission component 2 7 is also provided on the top of the workbench 1 near the transfer platform 51. A slide 2 8 is provided on the transmission component 2 7. The slide 2 8 can move back and forth under the drive of the transmission component 2 7, so that the placement platform 9 can be flexibly adjusted. The rear of the transfer platform 51 and the transmission component 2 7 are both located below the movement path of the slide 1 4. When the transmission component 1 3 drives the slide 1 4 to move to the right, the slide 1 4 will pass above the rear of the transmission component 2 7 and the transfer platform 51. The transfer platform 51 is provided with a groove for placing a tray. During the placement process, the tray containing the components to be placed is placed in the transfer platform 51 so that the placement head 6 can move quickly and pick up the components accurately. The placement head 6 accurately picks up the components from the transfer platform 51 and moves them above the placement platform 9 for placement.

[0023] The vacuum suction holes 910 on the feeding table 9 are connected to the negative pressure components in the feeding table 9, and through the work of the negative pressure components, the vacuum suction holes 910 can generate strong suction force to firmly adsorb the flexible circuit board on the surface of the feeding table 9. This multi-point vacuum adsorption method not only ensures the stability of the flexible circuit board during the patching process, but also avoids the patching deviation caused by the movement of the circuit board.

[0024] As shown in Figure 3 and Figure 4 The vacuum suction holes 910 of the feeding table 9 are divided into multiple control zones 920, and the number and distribution of the vacuum suction holes 910 in each control zone 920 are adjusted according to the specific size and shape of the flexible circuit board. The zoning design not only improves the flexibility and adaptability of adsorption, but also ensures that the flexible circuit board in each area can obtain the best fixing effect during the patching process. The negative pressure components in the feeding table 9 are provided with an integrated control console, which contains a central control system for controlling the adsorption state of the vacuum suction holes 910 in each control zone 920.

[0025] Specifically, the vacuum suction holes 910 in each control zone 920 are connected to the negative pressure components through independent air path pipes, which are precisely controlled by the solenoid valve group in the integrated control console. When the central control system receives the mounting instruction, it will dynamically adjust the on-off state of the solenoid valves of each control zone 920 according to the specific size, shape and required adsorption strength of the flexible circuit board, so as to realize fine adjustment of the adsorption force of the vacuum suction holes 910 in each zone. For example, for irregular-shaped or specially required flexible circuit boards, some control zones 920 may activate more vacuum suction holes 910 to enhance the adsorption force, while other zones can reduce the number of suction holes to avoid unnecessary adsorption interference. The flexible zoning control method significantly improves the stability and precision during the patching process. Since each control zone 920 can independently adjust the adsorption force according to the actual demand, the flexible circuit board always maintains the best fixed state on the feeding table 9, reducing the patching deviation caused by the movement of the circuit board. In addition, the integrated control console also has real-time monitoring function, which detects the working state of each control zone 920 through the built-in sensor and feeds back the data to the central control system. If an abnormal situation (such as insufficient adsorption force or leakage) occurs in a certain zone, the system will immediately issue an alarm and take corresponding measures to ensure the safety and reliability of the entire patching process.

[0026] At the beginning, the tray with components is placed on the material transfer table, the material transfer table 51 can be equipped with positioning components as needed to move the tray within a certain range to facilitate the pick-up and drop-off of the material by the patch head 6 on the transmission member 1 3. The drop-off table 9 is located at the limit position in front of the transmission member 2 7. The flexible circuit board that needs to be patched is placed flat on the drop-off table 9. Through the integrated control console and the central control system in the drop-off table 9, the vacuum suction holes 910 of the drop-off table 9 are divided into multiple independently controllable partitions 920. When the circuit board is adsorbed, the adsorption state of each partition is dynamically adjusted according to the specific size and shape of the flexible circuit board. Before patching, the area on the upward-facing side of the circuit board that needs to be patched is coated with solder. The transmission member 2 7 drives the drop-off table 7 to move backward to the area below the working area of the patch head 6. The patch head 6 picks up components from the material transfer table 51 and accurately positions them through the vision module. Then, under the cooperation of the sliding table 1 4, the drop-off table 9 and the air cylinder 1 5, the components are accurately patched onto the flexible circuit board. The entire process is monitored in real time by the detection module 1 62 to ensure accurate patching position. The integrated control module 61 continuously monitors the working state of each partition to handle abnormal situations in a timely manner, ensuring the safety and reliability of the patching process. Finally, after the patching is completed, the system stops the negative pressure adsorption, and the drop-off table 9 is controlled to move forward, and the operator takes out the patched flexible circuit board. This design significantly improves the precision and efficiency of patching.

[0027] Embodiment 2

[0028] Based on Embodiment 1, as shown in Figure 3 and Figure 4 , it also includes a stop bar 10, an air cylinder 2 1 and a positioning clamp 1 1 1. The top rear side of the drop-off table 9 is provided with a stop bar 10 to provide a fixed reference surface, ensuring that there is a clear reference position when the circuit board is placed. The rear left and right sides of the drop-off table 9 are each provided with an air cylinder 2 1. Each air cylinder 2 1 has a positioning clamp 1 1 1 mounted on its movable rod. When placing the circuit board, the side of the circuit board that needs to be patched is placed upward and tightly against the stop bar 10, and then the circuit board is placed stably on the drop-off table 9. Subsequently, the air cylinder 2 1 drives the positioning clamp 1 1 1 to move downward, firmly clamping the two corners of the rear side of the circuit board, ensuring that the circuit board does not shift during subsequent operations.

[0029] To further ensure the flatness of the circuit board, after the circuit board is placed, it can be smoothed forward on the drop-off table 9 by manual or additional smoothing components. The vacuum suction holes 910 controlled by the partition gradually activate according to the smoothing area, starting from one end of the circuit board and gradually expanding the adsorption force to the other end, ensuring that the circuit board is firmly fixed on the drop-off table 9 during the entire patching process. This gradual adsorption method not only improves the uniformity and stability of adsorption, but also effectively prevents deformation or damage of the circuit board caused by one-time full adsorption.

[0030] In addition, as shown in Figure 1 , Figure 3 and Figure 4 , the device further comprises a driving motor 12, a swing arm 121 and a detection module two 122. The front side of the second sliding table 8 is provided with a driving motor 12, the driving shaft of which is fixedly connected with the swing arm 121, and the swing arm 121 is installed with the detection module two 122, and the detection probe is vertically downward. The swing arm 121 can rotate under the drive of the driving motor 12, and the rotation path covers the space above the material placing table 9. After the patching is completed, the swing arm 121 will automatically rotate above the material placing table 9, and the detection module two 122 is used to detect the completed circuit board in real time. The detection module two 122 can accurately capture and analyze the patching situation on the circuit board, real-time feedback the mounting result, and timely find and correct the possible problems such as misplacement, missing or inclination. Through this automatic detection means, not only the detection accuracy and speed can be significantly improved, but also the errors caused by manual detection can be effectively avoided, and the stability and reliability of production are further enhanced.
