Description

Technical Field

[0001] This invention relates to the field of slipper assembly technology, and in particular to a slipper strap shaping and positioning mechanism. Background Technology

[0002] The application of slipper straps on production lines is primarily done manually, resulting in prolonged periods of strenuous labor and high physical exertion. Furthermore, slipper straps are mainly made of rubber, which is soft, easily deformed, difficult to position, and has unusual shapes, making automated positioning challenging. Currently, most slipper straps are shaped and positioned by hand before being glued, leading to high labor intensity and low production efficiency. Summary of the Invention

[0003] This invention provides a slipper strap shaping and positioning mechanism that can automatically shape and position the slipper strap surface to meet automated fitting requirements, greatly reducing the labor intensity of the human body and increasing the speed of slipper production.

[0004] The technical solution of the present invention is as follows:

[0005] A slipper strap shaping and positioning mechanism includes a frame and a base, wherein a movable gripping device is provided on the frame and a positioning device is provided on the base;

[0006] The mobile gripping device includes a moving mechanism and a connecting plate. One side of the connecting plate is fixed to the moving mechanism, and the bottom of the connecting plate is equipped with a gripping mechanism.

[0007] The positioning device includes a front positioning mechanism, a side blocking positioning mechanism, and a contour shoe mold base. The front positioning mechanism is located at the front end of the contour shoe mold base, and the side blocking positioning mechanism is located on both sides of the contour shoe mold base.

[0008] The slipper strap surface is placed on the molded shoe base. The gripping mechanism, in conjunction with the front positioning mechanism and the side blocking positioning mechanism, shapes and positions the slipper strap surface. Finally, the gripping mechanism grips the slipper strap surface.

[0009] Furthermore, the moving mechanism includes a rodless cylinder, a moving guide rail, a cable chain, a moving seat, and a lifting cylinder. The moving guide rail is located on one side of the rodless cylinder, and the cable chain is located on the other side of the rodless cylinder. A moving block is provided on the rodless cylinder, and a moving fixed block is provided on one side of the moving block. The other side of the moving fixed block is fixed to the moving seat. The moving seat is slidably connected to the moving guide rail via a slider. The lifting cylinder is fixed to one side of the moving seat, and the telescopic rod of the lifting cylinder is connected to one side of the connecting plate. One end of the cable chain is fixedly connected to the connecting plate.

[0010] Furthermore, both ends of the moving guide rail are provided with a first buffer.

[0011] Furthermore, a second buffer is provided on the top of the movable seat, and a cylinder limit block is provided on the top of the connecting plate that connects to the telescopic rod of the lifting cylinder.

[0012] Furthermore, the gripping mechanism includes a pneumatic gripper, a fixed plate, an arc-shaped contour suction cup, a connecting block, and a quick-lock pin. The pneumatic gripper is fixed to the bottom of the connecting plate by the fixed plate, the connecting block is fixed to the bottom of the pneumatic gripper, and the arc-shaped contour suction cup is fixed to the bottom of the connecting block by the quick-lock pin.

[0013] Furthermore, the arc-shaped suction cup is provided with several vacuum suction holes.

[0014] Furthermore, the front positioning mechanism includes a front positioning plate, a first cylinder, and an adjusting bracket. The bottom of the adjusting bracket is fixed on the base, the first cylinder is placed on the top of the adjusting bracket, and the telescopic rod of the first cylinder is fixedly connected to the front positioning plate. The two front positioning mechanisms are arranged in a group opposite to each other and are correspondingly located on both sides of the front end of one of the contour shoe mold bases.

[0015] Furthermore, the side blocking positioning mechanism includes a side positioning plate, a second cylinder, and a side fixing plate. The second cylinder is fixed to the base through the side fixing plate, and the telescopic rod of the second cylinder is fixedly connected to the side positioning plate. The two side blocking positioning mechanisms are respectively placed on both sides of one of the conformal shoe mold bases.

[0016] Furthermore, the contour shoe mold base includes a fixed base, an adjusting plate, adjusting bolts, a connecting base, and a contour shoe mold base body. The fixed base is fixed on the base, the adjusting plate is fixed on the fixed base by adjusting bolts, the connecting base is fixed on the adjusting plate, and the contour shoe mold base body is fixed on the top of the connecting base. The contour shoe mold base body is provided with several vacuum suction holes.

[0017] Furthermore, the base is provided with a plurality of positioning devices, and the bottom of the connecting plate is provided with a plurality of gripping mechanisms, with one positioning device corresponding to one gripping mechanism.

[0018] The slipper strap shaping and positioning mechanism consists of a moving gripping device and a positioning device. The entire mechanism is operated manually. The slipper strap is placed on the molded shoe base, where vacuum suction holes hold it in place. The moving mechanism moves the gripping mechanism above the molded shoe base and lowers it via a lifting cylinder. Once in position, the gripping mechanism's pneumatic claws drive the curved suction cups on both sides to press the slipper strap into a specific shape. At this point, the second cylinder of the side positioning mechanism in the positioning device rises to its limit, positioning the slipper strap in the height direction. The first cylinder of the front positioning mechanism extends, positioning the slipper strap in the front direction. Finally, the vacuum suction holes of the curved suction cups in the gripping mechanism suck up the slipper strap, fixing it to the suction cups and stopping the vacuum suction holes of the molded shoe base from holding it in place. Finally, the lifting cylinder raises the gripping mechanism, which is then moved by the moving mechanism to the bonding position for attaching the slipper strap.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention solves the technical difficulties of slipper strap surface deformation and positioning by shaping and positioning slipper strap surface through a slipper strap surface shaping and positioning mechanism; it also solves the connection of automated production of slipper strap surface, moving from manual to automated production and reducing labor intensity.

It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0030] Example 1:

[0031] like Figure 1 — Figure 7 As shown, a slipper strap shaping and positioning mechanism includes a frame 1 and a base 2. The frame 1 is equipped with a moving gripping device, and the base 2 is equipped with a positioning device.

[0032] The mobile gripping device is provided with a moving mechanism 3 and a connecting plate 4. One side of the connecting plate 4 is fixed to the moving mechanism 3, and a gripping mechanism 5 is provided at the bottom of the connecting plate 4.

[0033] The positioning device includes a front positioning mechanism 6, a side blocking positioning mechanism 7, and a contour shoe mold base 8. The front positioning mechanism 6 is located at the front end of the contour shoe mold base 8, and the side blocking positioning mechanism 7 is located on both sides of the contour shoe mold base 8.

[0034] The slipper strap surface is placed on the mold base 8. The gripping mechanism 5, together with the front positioning mechanism 6 and the side blocking positioning mechanism 7, shapes and positions the slipper strap surface. Finally, the gripping mechanism 5 grips the slipper strap surface.

[0035] See Figure 3 and Figure 4The moving mechanism 3 includes a rodless cylinder 301, a moving guide rail 302, a drag chain 303, a moving seat 304, and a lifting cylinder 305. The moving guide rail 302 is located on one side of the rodless cylinder 301, and the drag chain 303 is located on the other side of the rodless cylinder 301. A moving block 306 is provided on the rodless cylinder 301, and a moving fixing block 307 is provided on one side of the moving block 306. The other side of the moving fixing block 307 is fixed on the moving seat 304. The moving seat 304 is slidably connected to the moving guide rail 302 by a slider. The lifting cylinder 305 is fixed on one side of the moving seat 304, and the telescopic rod of the lifting cylinder 305 is connected to one side of the connecting plate 4. One end of the drag chain 303 is fixedly connected to the connecting plate 4.

[0036] The rodless cylinder 301 drives the moving block 306 to move. The moving block 306 moves the moving seat 304 on the moving guide rail 302 through the moving fixed block 307, and simultaneously drives the drag chain 303. When the moving seat 304 moves into place, the rodless cylinder 301 stops, and at the same time the lifting cylinder 305 starts. The lifting cylinder 305 drives the connecting plate 4 to descend, so that the gripping mechanism 5 at the bottom of the connecting plate 4 falls directly above the contour shoe mold seat 8 for shaping.

[0037] The movable guide rail 302 is equipped with a first buffer 308 at both ends to buffer and limit the movement of the movable seat 304; the top of the movable seat 304 is equipped with a second buffer 309; the top of the connecting plate 4 connected to the telescopic rod of the lifting cylinder 305 is equipped with a cylinder limit block 310; when the cylinder limit block 310 touches the second buffer 309, the lifting cylinder 305 descends to the position and stops.

[0038] See Figure 3 and Figure 4 The gripping mechanism 5 includes a pneumatic gripper 501, a fixing plate 502, an arc-shaped contour suction cup 503, a connecting block 504, and a quick-lock pin 505. The pneumatic gripper 501 is fixed to the bottom of the connecting plate 4 by the fixing plate 502, the connecting block 504 is fixed to the bottom of the pneumatic gripper 501, and the arc-shaped contour suction cup 503 is fixed to the bottom of the connecting block 504 by the quick-lock pin 505. The quick-lock pin 505 allows for quick replacement of the arc-shaped contour suction cup 503.

[0039] During the shaping operation, the pneumatic gripper 501 drives the arc-shaped contour suction cups 503 on both sides to shape and position the two sides of the slipper strap surface.

[0040] Among them, the arc-shaped suction cup 503 is equipped with several vacuum suction holes for picking up the shaped slipper strap surface.

[0041] See Figure 5 and Figure 6The front positioning mechanism 6 includes a front positioning plate 601, a first cylinder 602, and an adjusting bracket 603. The bottom of the adjusting bracket 603 is fixed on the base 2, and the first cylinder 602 is placed on the top of the adjusting bracket 603. The telescopic rod of the first cylinder 602 is fixedly connected to the front positioning plate 601. The two front positioning mechanisms 6 are arranged in a group and are correspondingly located on both sides of the front end of a contour shoe mold base 8.

[0042] During shaping, the first cylinder 602 is pushed out, driving the front positioning plate 601 to position the slipper strap in the front direction.

[0043] See Figure 5 and Figure 6 The side blocking positioning mechanism 7 includes a side positioning plate 701, a second cylinder 702, and a side fixing plate 703. The second cylinder 702 is fixed on the base 2 through the side fixing plate 703. The telescopic rod of the second cylinder 702 is fixedly connected to the side positioning plate 701. The two side blocking positioning mechanisms 7 are respectively placed on both sides of a contour shoe mold base 8.

[0044] During the shaping process, the second cylinder 702 rises to the limit position, and the side positioning plate 701 lifts up both sides of the slipper strap from the bottom, thereby positioning the height of the shoe surface.

[0045] See Figure 7 The contour shoe mold base 8 includes a fixed base 801, an adjusting plate 802, an adjusting bolt 803, a connecting base 804, and a contour shoe mold base body 805. The fixed base 801 is fixed to the base 2. The adjusting plate 802 is fixed to the fixed base 801 by the adjusting bolt 803. The connecting base 804 is fixed to the adjusting plate 802. The contour shoe mold base body 805 is fixed to the top of the connecting base 804. The contour shoe mold base body 805 is provided with several vacuum suction holes. The position of the contour shoe mold base body 805 can be finely adjusted by adjusting the bolt 803 to adapt to different sizes of slipper straps.

[0046] Before shaping, the slipper strap surface is placed manually on the mold base body 805, and the vacuum suction hole of the mold base body 805 sucks the slipper strap surface tightly; after shaping, the vacuum suction hole of the mold base body 805 stops sucking, and the slipper strap surface is grabbed and taken away by the gripping mechanism 5.

[0047] See Figure 1 and Figure 2 The base 2 can be equipped with multiple positioning devices, and the bottom of the connecting plate 4 can be equipped with multiple gripping mechanisms 5. One positioning device corresponds to one gripping mechanism 5, which can perform multiple shoe upper shaping at the same time, improving work efficiency. In this embodiment, two are set.

[0048] Working principle of the invention:

[0049] The slipper strap shaping and positioning mechanism consists of a moving gripping device and a positioning device. The entire mechanism is operated by manually placing the slipper strap onto the contour shoe mold base 805. The vacuum suction holes of the contour shoe mold base 805 hold the slipper strap tightly. Then, the rodless cylinder 301 drives the moving block 306 to move. The moving block 306, through the moving fixed block 307, causes the moving seat 304 to slide on the moving guide rail 302, simultaneously driving the drag chain 303. When the moving seat 304 is in position, the rodless cylinder 301 stops, and the lifting cylinder 305 starts, causing the connecting plate 4 to descend, so that the gripping mechanism 5 at the bottom of the connecting plate 4 falls directly above the contour shoe mold base 805. After the gripping mechanism 5 is in position, it drives the pneumatic gripper 501, causing the arc-shaped contour suction cups 503 on both sides to press the slipper strap onto the mold base 805. Once a certain shape is formed, the second cylinder 702 of the side positioning mechanism 7 is driven to rise. After the second cylinder 702 reaches the limit, the side positioning plate 701 lifts the two sides of the slipper strap surface from the bottom, thereby positioning the height of the shoe surface. At the same time, the first cylinder 602 of the front positioning mechanism 6 is driven to push out, and the front positioning plate 601 positions the slipper strap surface in the facing direction. Finally, the vacuum suction hole of the arc-shaped contour suction cup 503 in the gripping mechanism 5 is used to pick up the slipper strap surface, which is fixed on the arc-shaped contour suction cup 503. The vacuum suction hole of the contour shoe mold body 805 stops suctioning the slipper strap surface. Finally, the lifting cylinder 305 drives the gripping mechanism 5 to rise through the connecting plate 4, and the moving mechanism 3 moves it to the bonding position to stick the slipper strap surface.

[0050] This invention enables automatic shaping and positioning of slipper straps, meeting automated fitting requirements, greatly reducing the labor intensity of the human body, and increasing the speed of slipper production.
