Description

Technical Field

[0001] This utility model belongs to the field of CCL / PCB electronic circuit industry, specifically relating to a semi-cured glass fiber cloth (PP) sheet palletizing and separating combination machine technology, and a glass fiber cloth PP sheet lifting and separating integrated machine. Background Technology

[0002] A PP separator is a mechanical device specifically designed for separating stacked or assembled (PP) sheets into circuit boards. It primarily functions by physically or mechanically separating and combining stacked (PP) sheets or other materials (such as metal plates or copper foil) to achieve various material combinations in the electronic circuit board manufacturing process.

[0003] Domestic utility model patent application number CN202223472156.9 discloses a (PP) separation device, including a frame, a positioning base at the upper left rear corner of the frame, a transport positioning mechanism at the front end of the positioning base, a transport arm at the front end of the transport positioning mechanism, and a sorting positioning mechanism at the upper right rear corner of the frame, with a sorting arm at the front end of the sorting positioning mechanism. By providing shovel-like devices at the lower ends of both the transport arm and the sorting arm, the shovel claws can accurately separate individual components. The machine scoops up and lifts individual PP sheets, pressing them together with a clamping head during the lifting process. This allows the topmost PP sheet to be quickly, accurately, and stably separated from the stack. Separation auxiliary devices are installed on both the front and rear sides of the upper frame, allowing the lifted PP sheet to be separated by sliding a separation lever to break the vacuum. This makes the separation faster and easier, preventing the PP sheets from being unable to separate due to excessive static electricity and vacuum adhesion. However, this invention directly uses a scooping claw to lift and separate individual PP sheets to prevent this problem. PP sheets (fiberglass cloth) have relatively low abrasion resistance, and the direct scooping process can easily cause wear to their surface, affecting the usability of the produced semi-solid fiberglass cloth (PP sheets). Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a glass fiber cloth PP sheet lifting and separating integrated machine, including a bottom frame, side frames fixedly installed at the four corners of the bottom frame, a top frame fixedly installed on the top of the side frames, and a fixed frame fixedly installed on the inner ring of the top frame. A lifting cylinder is installed on the top of the bottom frame at the position of the side frames, and a lifting frame that slides with the side frames is fixedly installed on the top of the lifting cylinder. A conveyor frame is fixedly installed between the lifting frames on the top of the bottom frame, and a transmission and conveying mechanism for conveying (PP) sheets is fixedly installed inside the conveyor frame. A sliding frame is slidably installed on the fixed frame, and a pushing cylinder for driving the sliding frame is fixedly installed on the conveyor frame. A lifting cylinder is fixedly installed on the sliding frame, and a separating mechanism is fixedly installed at the end of the lifting cylinder.

[0005] As a further preferred technical solution of this utility model; the bottom of the sliding frame is fixedly installed with a positioning slide rail at the top of the fixed frame, and the bottom of the sliding frame is slidably installed on the positioning slide rail; a vacuum pump body is fixedly installed on one side of the top of the sliding frame; a docking frame is fixedly installed at the bottom of the sliding frame; a connecting plate is fixedly installed at the bottom of the docking frame; side sliders are fixedly installed on both sides between the docking frame and the connecting plate; the bottom of the lifting cylinder has a pushing end that passes through the connecting plate, and a mounting bracket is fixedly installed at the bottom of the pushing end.

[0006] By pushing the hydraulic cylinder to move the sliding frame, the position of the sliding frame is moved more precisely to the designated position to operate the (PP) plate.

[0007] As a further preferred technical solution of this utility model, the separation mechanism includes a connecting base frame fixedly installed with the mounting frame, two sets of telescopic frames fixedly installed on the top of the connecting base frame, an extension frame fixedly installed on one side of the top of the connecting base frame, a vacuum adsorption mechanism fixedly installed at the end of the extension frame, and three sets of bottom support mechanisms fixedly installed on the side of the connecting base frame. A fixed slide rail is fixedly installed on the inner side of the telescopic frame, and the side slider is slidably installed with the fixed slide rail.

[0008] The separation mechanism is moved to a designated position by a lifting cylinder, and the fixed slide rail on the telescopic frame slides on the side of the docking frame and the connecting plate to ensure the stability of the separation mechanism.

[0009] As a further preferred technical solution of this utility model; the vacuum adsorption mechanism includes a mounting box fixedly installed with the extension frame, an adjusting screw threaded through the mounting box, and a positioning rod penetrating the mounting box. The bottom of the adjusting screw is fixedly installed with the bottom of the inner cavity of the mounting box by a fixed bearing. The top of the adjusting screw is installed with a rotating handle through the mounting box. The top and bottom of the positioning rod are both installed through the mounting box and fixedly installed with the mounting box by a positioning bearing. Lifting plates extending out of the mounting box are respectively installed through and threaded through the positioning rod and the adjusting screw. An adsorption cylinder is fixedly installed on the lifting plate, and a vacuum suction cup is fixedly installed at the bottom of the adsorption cylinder. The vacuum suction cup is connected to the vacuum pump body through a sealed flexible tube.

[0010] The separation mechanism is moved to its approximate position by the action of the hydraulic cylinder and the lifting cylinder. The precise position of the vacuum suction cup is adjusted by rotating the handle to ensure that it contacts and adsorbs the top of the (PP) plate under the action of the adsorption cylinder. After the adsorption cylinder pushes the vacuum suction cup to adhere to the top of the (PP) plate, the vacuum pump body evacuates the air inside the vacuum suction cup to adsorb the top of the (PP) sheet, thereby separating the stacked (PP) sheets.

[0011] As a further preferred technical solution of this utility model, the bottom support mechanism includes a positioning plate fixedly installed on the side of the connecting base frame, a bottom support cylinder fixedly installed on the positioning plate, a connecting seat fixedly installed at the bottom pushing position of the bottom support cylinder, and a pushing cylinder fixedly installed at the bottom of the connecting seat. A movable bottom support plate is fixedly installed at the end of the pushing cylinder, and a positioning cylinder is fixedly installed on the side of the movable bottom support plate. A clamping block is pushed and installed at the bottom of the positioning cylinder. Fork connecting plates are fixedly installed on both sides of the connecting seat, and a triangular fork is fixedly installed at one end of the fork connecting plate.

[0012] The bottom-supporting cylinder is controlled according to the position of the (PP) sheet and the position of the adsorption cylinder, so that the triangular fork is always located at the boundary of the (PP) sheet and at the dividing point between the two sets of (PP) sheets. After the vacuum suction cup achieves the adsorption and separation effect of the (PP) sheet, the movable bottom-supporting plate is moved forward by the pushing cylinder. The movable bottom-supporting plate supports the bottom of the (PP) sheet, and then the positioning cylinder pushes the clamping block to clamp the (PP) sheet, and lifts and separates it, ensuring that the (PP) sheet does not fall off during the lifting and transfer process, and improving the stability of the (PP) sheet separation.

[0013] As a further preferred technical solution of this utility model, the transmission and conveying mechanism includes multiple sets of conveying rollers, bearing seats that are connected to both ends of the conveying rollers and fixedly installed on the top of the conveyor frame, a sprocket set fixedly installed on one side of the bearing seat, a transmission chain that is connected between the sprocket sets, and a drive motor fixedly installed on the conveyor frame for driving the conveying rollers to rotate. The output end of the drive motor is fixedly connected to one end of a set of conveying rollers.

[0014] The conveyor rollers are driven by a drive motor to rotate. With the sprocket set and the transmission chain connected, multiple sets of conveyor rollers rotate to achieve the effect of conveying (PP) sheets.

[0015] As a further preferred technical solution of this utility model; a protective plate is fixedly installed on the inner side of the conveyor frame, and two sets of fixing plates are fixedly installed at the bottom of the conveyor frame between the conveying rollers. Two sets of clamping cylinders are symmetrically installed at the top middle position of the fixing plates. A connecting slide is fixedly installed on the top of the fixing plate at the end of the clamping cylinder. An adjusting frame is pushed and installed at the end of the clamping cylinder, and the bottom of the adjusting frame is slidably installed on the connecting slide. The four corners of the conveyor frame are fixedly installed to the protective plate through connecting blocks.

[0016] The clamping cylinder pushes the adjusting frame to slide on the fixed plate, integrating the (PP) plates that have shifted position, ensuring that the (PP) plates are always in the central axis position of the conveying roller, which facilitates the separation operation.

[0017] Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: 1. First, the vacuum suction cup is evacuated by the vacuum pump to adsorb the top of the (PP) sheets, thus separating the stacked (PP) sheets. During this process, the bottom support cylinder is controlled according to the position of the (PP) sheets and the position of the adsorption cylinder, so that the triangular fork is always located at the boundary of the (PP) sheets and at the dividing point between the two groups of (PP) sheets, ensuring that there is a gap between the two groups of (PP) sheets and reducing electrostatic adsorption. After the vacuum suction cup achieves the adsorption and separation effect on the (PP) sheets, the movable bottom support plate is moved forward by the push cylinder. The movable bottom support plate supports the bottom of the (PP) sheets to ensure complete separation of the (PP) sheets and reduce wear on the (PP) sheets.

[0018] 2. By pushing the cylinder to move the movable base plate forward, the movable base plate supports the bottom of the (PP) sheet. Then, the positioning cylinder pushes the clamping block to clamp the (PP) sheet, lifting and separating it to ensure that the (PP) sheet does not fall off during the lifting and transfer process, thus improving the stability of the (PP) sheet during separation.

Lifting plates 836 extending out of the mounting box 831 are respectively threaded through and mounted on the positioning rod 832 and the adjusting screw 833. The mounting box 831 at the position of the lifting plate 836 has an opening for the lifting plate 836 to move up and down. An adsorption cylinder 837 is fixedly mounted on the lifting plate 836, and a vacuum suction cup 838 is fixedly mounted on the bottom of the adsorption cylinder 837. The vacuum suction cup 838 is connected to the vacuum pump body 61 via a sealed flexible hose. Under the action of the hydraulic cylinder 5 and the lifting cylinder 7, the separation mechanism 8 is moved to the approximate position, and the precise position of the vacuum suction cup 838 is adjusted by rotating the rotating handle 835 to ensure that it contacts and adsorbs the top of the (PP) sheet under the action of the adsorption cylinder 837. After the adsorption cylinder 837 pushes the vacuum suction cup 838 to adhere to the top of the (PP) sheet, the vacuum pump body 61 evacuates the air inside the vacuum suction cup 838 to adsorb the top of the (PP) sheet, thereby separating the stacked (PP) sheets.

During the transfer process, the separation mechanism 8 is moved to its approximate position by the push cylinder 5 and the lifting cylinder 7. The precise position of the vacuum suction cup 838 is adjusted by rotating the handle 835 to ensure that it contacts and adsorbs the top of the (PP) sheet under the action of the adsorption cylinder 837.
