Description

Technical Field

[0001] This utility model relates to the field of board-throwing machine technology, specifically a double-row flexible board removable pad paper type board-throwing machine. Background Technology

[0002] In the field of modern electronic equipment manufacturing, as electronic products develop towards miniaturization, lightweighting, and high performance, the demand for flexible circuit boards (flexible boards) is increasing day by day.

[0003] Flexible printed circuit boards (FPCBs) are widely used in various electronic products such as smartphones, tablets, and wearable devices due to their unique advantages such as high wiring density, light weight, thinness, and good flexibility, becoming one of the key components driving the progress of electronic technology.

[0004] In the production and processing of flexible printed circuit boards (FPCBs), separating the FPCB from the backing paper and accurately delivering it to the subsequent processing station is an extremely important initial step.

[0005] During the production, transportation, or storage of flexible printed circuit boards, unevenness may occur on the surface due to various reasons.

[0006] Traditional automated plate-feeding equipment often has a fixed adsorption structure when faced with uneven surfaces of flexible plates, and it cannot automatically adjust according to the actual conditions of the flexible plate surface.

[0007] This leads to problems with weak adhesion when adsorbing flexible circuit boards. During the transfer process, the flexible circuit boards may shift or even fall off, which seriously affects the continuity and stability of production. It also cannot guarantee the safety of the flexible circuit boards during the transfer process. As a result, the processing quality of the flexible circuit boards in subsequent processing is reduced due to the displacement and damage in the early stage, which increases the defect rate and increases the production cost.

[0008] In view of the above, this application is hereby submitted. Utility Model Content

One end of the sliding rod is connected to a connecting plate, and one end of an air bladder is fixedly connected to the connecting plate. The other end of the air bladder is fixedly connected to the mounting plate, and a suction cup is fixedly connected to the other end of the sliding rod. The suction cup is hollow, and the cavity of the suction cup communicates with the air bladder. A negative pressure hole communicating with the cavity is opened on the suction cup.

[0011] Furthermore, the mounting plate has air holes, and an air tube is inserted into the air holes. The two ends of the air tube are respectively connected to the airbag and the suction cup. The air tube is a spring tube.

[0012] Furthermore, there are three sliding holes, three sliding rods, and the connecting plate is triangular, with the sliding rods connected to the triangular part of the connecting plate.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figure 1-3 This utility model provides a technical solution:

[0026] A double-row flexible board paper removal and feeding machine includes a mounting frame 1, a hydraulic lifting component 2, and a spacing adjustment guide rail 3. A mounting plate 4 is connected to the spacing adjustment guide rail 3. A transverse guide rail 11 is provided on the mounting frame 1. A transverse base 12 is installed on the transverse guide rail 11. The hydraulic lifting component 2 is installed on the transverse base 12. The top two ends of the spacing adjustment guide rail 3 are fixedly connected to the hydraulic lifting component 2. Two spacing adjustment bases 31 are installed on the spacing adjustment guide rail 3. The mounting plate 4 is connected to the spacing adjustment bases 31.

[0027] The mounting plate 4 has a sliding hole 41, and a sliding rod 5 is slidably connected in the sliding hole 41. One end of the sliding rod 5 is connected to a connecting plate 51, and one end of an airbag 52 is fixedly connected to the connecting plate 51. The other end of the airbag 52 is fixedly connected to the mounting plate 4, and a suction cup 54 is fixedly connected to the other end of the sliding rod 5.

[0028] The suction cup 54 is hollow, and the mounting plate 4 has an air hole 42. An air tube 53 is inserted into the air hole 42. The two ends of the air tube 53 are connected to the air bag 52 and the suction cup 54 respectively. The air tube 53 is a spring tube 6. The suction cup 54 has a negative pressure hole 55 that communicates with the cavity.

[0029] Connect the power supply to the double-row flexible board paper-feeding machine and check whether the hydraulic lifting component 2, spacing adjustment guide rail 3, and transverse guide rail 11 are in normal working condition. Ensure that the air pipe 53 and air bag 52 are tightly connected and leak-free. Place the double-row flexible boards to be processed neatly on the paper-feeding station below the feeding machine.

[0030] Start the transverse guide rail 11, allowing the transverse base 12 to slide on the transverse guide rail 11, and move the hydraulic lifting component 2 and the spacing adjustment guide rail 3 to a suitable transverse position for subsequent operation of the flexible plate.

[0031] The positions of the two spacing adjustment bases 31 are adjusted by adjusting the spacing adjustment guide rail 3 so that the spacing between the mounting plates 4 is adapted to the width of the double-row flexible boards.

[0032] Next, the hydraulic lifting component 2 is activated, causing the spacing adjustment guide rail 3 to descend, gradually bringing the suction cup 54 on the mounting plate 4 closer to the flexible plate. When the suction cup 54 contacts the flexible plate, the surface of the flexible plate pushes the suction cup 54, causing the slide rod 5 to move upward. The connecting plate 51 connected to one end of the slide rod 5 stretches the airbag 52, increasing the internal space of the airbag 52 and reducing the air pressure. The negative pressure is transmitted to the negative pressure hole 55 of the suction cup 54 through the air pipe 53, thereby forming a negative pressure adsorption force between the suction cup 54 and the flexible plate, adsorbing the flexible plate onto the suction cup 54, and simultaneously separating the flexible plate from the bottom paper pad.

[0033] After the suction cup 54 has stably adsorbed the soft board, the horizontal guide rail 11 is started again. The horizontal base 12 drives the component adsorbing the soft board to move and transport the soft board to the next processing step.

[0034] Upon reaching the designated workstation, the negative pressure between the suction cup 54 and the flexible board is eliminated by controlling the airbag 52 to release the air, causing the flexible board to detach from the suction cup 54 and completing the board feeding operation. The equipment can then repeat the above steps to process the next set of flexible boards.

[0035] Through the coordinated operation of the hydraulic lifting component 2, the spacing adjustment guide rail 3, and the transverse guide rail 11, the adsorption, separation of paper pads, and transfer of flexible boards can be achieved quickly. The degree of automation is high, which greatly improves the efficiency of removing paper pads and feeding boards for double-row flexible boards compared with manual operation, reduces production time, and improves overall production efficiency.

[0036] The spacing adjustment guide rail 3 can flexibly adjust the spacing between the mounting plates 4, which can adapt to double-row flexible boards of different widths, enhance the versatility of the equipment, reduce the cost and time of replacing the equipment due to changes in the flexible board specifications, and expand the application range of the equipment.

[0037] The adsorption structure, consisting of suction cups 54, sliding rods 5, and air bladders 52, can automatically adjust according to the unevenness of the soft board surface. When the soft board surface has different heights, multiple sets of suction cups 54 can contact the soft board at different heights. The negative pressure generated by the stretching of the air bladders 52 achieves a tighter and more uniform adsorption on the soft board surface, avoiding problems such as weak adsorption and displacement caused by uneven soft board surface. This ensures the stability and safety of the soft board during the transfer process and improves the processing quality.

[0038] There are three sliding holes 41, three sliding rods 5, and the connecting plate 51 is triangular. The sliding rods 5 are connected to the triangular part of the connecting plate 51.

[0039] Springs 6 are provided on the inner side of the three slide rods 5. Springs 6 are coaxial with air holes 42. Springs 6 are located on the outer side of air tube 53. The two ends of springs 6 are fixedly connected to mounting plate 4 and suction cup 54 respectively.

[0040] The slide bar is divided into four groups of three, with each group having three bars, and they are spaced out at the four corners of the mounting plate 4.

[0041] The negative pressure holes 55 are distributed at intervals, and the suction cup 54 is provided with a rubber pad 7, which has a notch that matches the negative pressure holes 55.

[0042] The sliding hole 41 and the sliding rod 5 are set in three places. The connecting plate 51 is triangular and connected to the triangular part of the sliding rod 5. This structural design enables the suction cup 54 to form a stable triangular force system when adsorbing the soft plate.

[0043] When pressure is applied to the surface of the flexible plate, the three sliding rods 5 are simultaneously subjected to force. The pressure is evenly distributed through the geometric stability of the triangle, which avoids the suction cup 54 from tilting or shifting due to uneven force. Even if the local pressure on the surface of the flexible plate changes, it can ensure that the suction cup 54 is tightly attached to the flexible plate, further improving the adsorption reliability.

[0044] Springs 6 are installed on the inner side of the three slide rods 5, coaxial with the air hole 42 and located on the outer side of the air tube 53. During the process of the suction cup 54 contacting the soft plate, the springs 6 play a buffering and resetting role.

[0045] When the surface of the flexible circuit board is uneven, and the suction cup 54 is pressed upward, the spring 6 is compressed to absorb the impact force, preventing the suction cup 54 from damaging the flexible circuit board due to rigid collision.

[0046] After adsorption is complete, spring 6 provides a rebound force to help suction cup 54 quickly reset, facilitating the next adsorption operation. At the same time, the elastic support of spring 6 allows suction cup 54 to more flexibly adapt to changes in the height of the flexible board surface, enhancing the equipment's ability to handle flexible boards with complex surfaces.

[0047] The slide bar 5 is divided into four groups of three, with each group of three bars spaced apart at the four corners of the mounting plate 4. This layout significantly increases the number of contact points between the suction cup 54 and the soft plate, forming a wider adsorption area.

[0048] It can effectively adsorb the edges and corners of flexible boards, avoiding blind spots. When adsorbing large or irregularly shaped flexible boards, it exerts force at all four corners to ensure that the flexible board is subjected to uniform force, preventing the flexible board from twisting or deforming during the transfer process and improving the pretreatment quality of the flexible board before processing.

[0049] Multiple spaced negative pressure holes 55 increase the negative pressure area, resulting in a stronger and more uniform adsorption force between the suction cup 54 and the flexible plate.

[0050] The suction cup 54 is equipped with a rubber pad 7 with an adaptive notch. The rubber pad 7 has good flexibility and elasticity, which can closely fit the surface of the soft board, fill the tiny gaps, effectively prevent air from entering, and enhance the sealing effect.

[0051] The notch corresponds to the negative pressure hole 55 to ensure smooth negative pressure transmission, further improving adsorption efficiency and stability. At the same time, the rubber pad 7 can also protect the surface of the soft plate and prevent scratches and wear during adsorption.
