Description

Technical Field

[0001] This utility model relates to the field of punching device technology, and in particular to an automatic positioning punching device for butyl rubber stoppers. Background Technology

[0002] In the manufacturing process of butyl rubber stoppers, square rubber sheets need to be cut into circular sheets, which are then sent for molding. To ensure safety during the punching process, the traditional manual feeding method has been eliminated and replaced by robotic feeding. However, while this improvement enhances safety, it also introduces new problems:

[0003] 1. Positioning and resetting of conveyor belts and positioning and loading of blanking machines usually require two robotic arms and a transfer positioning platform. One robotic arm picks up and places materials on the positioning platform, while the other robotic arm picks up materials from the positioning platform and places them on the blanking machine. This results in high equipment and maintenance costs.

[0004] 2. Although the robotic arm has replaced some manual operations, the cleaning of waste materials still depends on manual labor. Moreover, due to the problem of waste materials sticking to the mold after punching, the cleaning work is quite heavy and increases the labor intensity. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that the cost of using robotic arms is high and the labor intensity of manual waste cleaning is high.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an automatic positioning and punching device for butyl rubber stoppers, including a punching machine, a support frame arranged in front of the punching machine, a feeding belt arranged between the punching machine and the support frame for transporting the film, and a feeding rack slidably arranged on the support frame. The feeding rack is perpendicular to the feeding belt and slidably arranged towards the punching machine. The feeding rack has an L-shaped structure, and its top end is slidably connected to the support frame. The bottom end of the feeding rack is vertically slidably connected to a suction cup structure. The unloading end of the feeding belt is provided with a positioning structure. A blowing nozzle is arranged on one side of the cutting template of the punching machine, and a waste bin is arranged on the other side.

[0007] Preferably, the lower template of the cutting template has material holes evenly distributed, a product box is provided below the lower template, and a guide plate is inclinedly arranged on the side of the lower template near the waste box, with the bottom end of the guide plate connected to the top opening of the waste box.

[0008] Preferably, the positioning structure includes a positioning plate arranged horizontally and vertically at the tail end of the feeding belt, a proximity switch arranged on the side wall of the positioning plate near the upstream of the feeding belt, the film being vertically stacked inside the material box, and the proximity switch being located below the top surface of the material box.

[0009] Preferably, positioning rods are vertically fixed on both sides of the top of the material box, and the positioning rods are in contact with both sides of the film.

[0010] Preferably, the support frame includes a frame body with a rectangular frame structure, a lead screw is horizontally rotatably arranged at the top center of the frame body, and a sliding rod is arranged perpendicularly to the lead screw at the top of the feeding frame. The two ends of the sliding rod are slidably connected to the rods on both sides of the frame body, and the middle part of the sliding rod is threadedly connected to the lead screw.

[0011] Preferably, the feeding frame includes an L-shaped connecting frame, inclined rods arranged at an angle and connected to both ends of the connecting frame, a top frame horizontally fixed to the bottom end of the connecting frame, and a lifting frame vertically slidably connected to the top frame. A lifting rod is vertically fixedly connected to the top of the lifting frame, and a rack is connected in parallel to the lifting rod. A gear that meshes with the rack is rotatably arranged on the top frame. Vacuum suction cups are evenly arranged on the lifting frame. The length and width of the lifting frame are both smaller than the length and width of the film.

[0012] This invention provides an automatic positioning and punching device for butyl rubber stoppers. The device transports boxed rubber sheets via a feeding belt, and positions the material using a positioning structure at the end of the feeding belt. A support frame drives an L-shaped feeding frame, which in turn moves the sheet. A vacuum suction cup at the bottom of the feeding frame adsorbs the rubber sheet and directly conveys it between the upper and lower dies of the punching machine for punching. Waste material generated after punching is blown into a waste bin through a blower. The punched product is directly collected in a product box. The automatic positioning and punching device has a simple structure and low cost. Its installation and arrangement according to the position of the cutting template inside the punching machine ensures high feeding accuracy and automatic unloading, avoiding excessive manual intervention and improving the quality and efficiency of punching.

[0018] like Figure 1-3 As shown, this utility model provides an automatic positioning and punching device for butyl rubber stoppers, including a punching machine 1, a support frame 5 arranged on the front of the punching machine 1, a feeding belt 2 arranged between the punching machine 1 and the support frame 5 for transporting the film 4, and a feeding rack 6 slidably arranged on the support frame 5. The feeding rack 6 is perpendicular to the feeding belt 2 and slidably arranged towards the punching machine 1. The feeding rack 6 has an L-shaped structure, and its top end is slidably connected to the support frame 5. The bottom end of the feeding rack 6 is vertically slidably connected to a suction cup structure. The unloading end of the feeding belt 2 is provided with a positioning structure. A blowing nozzle 14 is arranged on one side of the cutting template 11 of the punching machine 1, and a waste bin 13 is arranged on the other side.

[0019] An L-shaped feeding rack 6 structure is adopted. When the feeding rack 6 is located at both ends of the support frame 5, the bottom of the feeding rack 6 is positioned directly above the film 4 on the feeding belt 2 and between the upper and lower molds of the cutting template 11. The feeding or unloading is achieved by controlling the descent of the suction cup structure at the bottom of the feeding rack 6.

[0020] During the punching of film 4, film 4 is stacked and placed in material box 3. Material box 3 is transported by feeding belt 2. When material box 3 contacts proximity switch 22, proximity switch 22 transmits a signal to the rotation drive control unit of feeding belt 2, causing feeding belt 2 to stop rotating, thus positioning film 4 on feeding belt 2. Then, the drive motor of lead screw 52 in support frame 5 drives lead screw 52 to rotate, causing feeding frame 6 to move along lead screw 52. The movable end (i.e., bottom end) of feeding frame 6 is moved to directly above the positioned film 4. After the lifting frame 613 at the bottom of feeding frame 6 moves downward to a set height, the vacuum suction cup on lifting frame 613... The top surface of the film 4 is contacted by the vacuum suction cup 605, and then the film 4 is adsorbed by the vacuum suction cup 605. Then the lifting frame 613 is controlled to move upward, and then the feeding frame 6 is controlled to move towards the inside of the punching machine 1, moving the lifting frame 613 between the upper and lower dies of the cutting template 11. Then the lifting frame 613 moves downward and places the film 4 on the lower die. The lifting frame 613 is retracted, and the feeding frame 6 adsorbs the film 4. The punching machine 1 punches the film 4. The punched product falls directly into the product box through the material hole. After the upper and lower dies are separated, the blowing nozzle 14 blows compressed air to blow the waste on the lower die into the waste box 13. Then the feeding frame 6 feeds the material again.

[0021] like Figure 1 As shown. The lower die of the cutting template 11 has material holes evenly distributed on it. A product box is located below the lower die. A guide plate 12 is inclinedly arranged on the side of the lower die near the waste box 13. The bottom end of the guide plate 12 is connected to the top opening of the waste box 13. The punching machine 1 controls the upper die of the cutting template 11 to move downward, cooperating with the lower die to punch the film 4. The punched product falls directly into the product box through the material holes. The punched waste is compressed and controlled by the blowing nozzle 14 to move towards the waste box 13 and slides into the waste box 13 through the guide plate 12.

[0022] like Figure 1 and Figure 2 As shown. The positioning structure includes a positioning plate 21 arranged horizontally and vertically at the tail end of the feeding belt 2. A proximity switch 22 is arranged on the side wall of the positioning plate 21 near the upstream of the feeding belt 2. The film 4 is vertically stacked in the material box 3, and the proximity switch 22 is located below the top surface of the material box 3.

[0023] The proximity switch 22 is interlocked with the rotation drive motor of the feeding belt 2. After the material box 3 moves and is detected by the proximity switch 22, the proximity switch 22 transmits a signal to the rotation drive motor of the feeding belt 2, and the feeding belt 2 stops rotating to position the film 4 in the X-axis direction. A gap is set between the inner side wall of the frame on both sides of the feeding belt 2 and the opposite outer side wall of the material box 3 to position the film 4 in the Y-axis direction.

[0024] The number of film sheets 4 loaded into the material box 3 at one time is fixed. After each material is retrieved, the lifting frame 613 descends a distance that increases by the thickness of one film sheet 4 to perform positioning in the Y-axis direction.

[0025] like Figure 1 and Figure 2 As shown. Positioning rods are vertically fixed on both sides of the top of the material box 3, and both sides of the film 4 are in contact with the positioning rods. The positioning rods limit the film 4 above the material box 3 in the X-axis direction, preventing the film 4 at the top from sliding due to the inertia of movement.

[0026] like Figure 2 As shown. The support frame 5 includes a frame body 51 with a rectangular frame structure. A lead screw 52 is horizontally rotatably arranged at the top center of the frame body 51. A sliding rod is arranged perpendicular to the lead screw 52 at the top of the feeding frame 6. The two ends of the sliding rod are slidably connected to the rods on both sides of the frame body 51, and the middle part of the sliding rod is threaded to the lead screw 52.

[0027] A lead screw 52 is rotatably arranged on the top of the frame 51. The feeding rack 6 is slidably limited by the two ends of the rod. A drive motor is installed on the top of the frame 51. The output shaft of the drive motor is coaxially and fixedly connected to one end of the lead screw 52. The drive motor drives the lead screw 52 to rotate. During the rotation of the lead screw 52, ​​the feeding rack 6 moves along the lead screw 52.

[0028] like Figure 2 and Figure 3 As shown. The feeding frame 6 includes an L-shaped connecting frame 601, an inclined rod 602 that is arranged at an angle and connected to both ends of the connecting frame 601, a top frame 603 that is horizontally fixed to the bottom end of the connecting frame 601, and a lifting frame 613 that is vertically slidably connected to the top frame 603. A lifting rod 608 is vertically fixed to the top of the lifting frame 613, and a rack 609 is connected in parallel to the lifting rod 608. A gear 611 that meshes with the rack 609 is rotatably arranged on the top frame 603. Vacuum suction cups 605 are evenly arranged on the lifting frame 613. The length and width of the lifting frame 613 are both smaller than the length and width of the film 4.

[0029] An opening is made in the top frame 603 for the lifting rod 608 to pass through, serving as a guide for the movement of the lifting rod 608. Mounting seats 610 are arranged on both sides of the top frame 603, and a mounting shaft is rotatably connected between the two mounting seats 610. A gear 611 is fixed to the mounting shaft, and a lifting motor 612 is arranged at one end of the mounting shaft. The output shaft of the lifting motor 612 is coaxially and fixedly connected to the mounting shaft. The lifting motor 612 drives the gear 611 to rotate, and the gear 611, through its meshing rack 609, drives the lifting frame 613 to move vertically. The length and width of the lifting frame 613 are smaller than the length and width of the film 4, allowing the lifting frame 613 to extend into the material box 3 for material retrieval and simultaneously enter the punching machine 1 for material unloading.

[0030] A connecting rod 604 is vertically fixed to the inner side of the bottom end of the connecting frame 601, and a top frame 603 is fixedly connected to the bottom end of the connecting rod 604. A sleeve 607 is vertically arranged in the middle of the bottom end of the connecting frame 601, and an air pipe 606 connected to the top of the vacuum suction cup 605 passes through the sleeve 607.
