Description

Technical Field

[0001] The invention relates to the field of inlay injection molding technology, in particular to a PET fabric layered feeding structure. Background Art

[0002] The PET inlay material used in the inlay injection molding process is increasingly widely used. The PET fabric used is a material with a diameter of 0.8mm and a 1X2mm hollow grid structure. The inlay injection molding process requires that a piece of the fabric be placed in a specified position for one part to be formed. In the process of realizing the automated production of inlay injection molding, a structure that can provide one piece of the fabric at a time is needed to provide materials for the process. The commonly used grasping needle structure in the industry is generally a steel needle with a diameter of about 1.5mm. A certain number of steel needles are arranged in an X shape, and pneumatic energy is used to drive the steel needles to move to achieve the grasping function. However, due to the large hollow size of the fabric, the needle tip is very easy to pierce two pieces of fabric during the grasping process of the steel needle, which cannot meet the demand of one piece of fabric at a time. Summary of the invention

[0003] The purpose of the present invention is to solve the above deficiencies in the prior art and provide a PET fabric layered feeding structure.

[0004] In order to achieve the above objectives, the following technical solutions are provided:

[0005] A PET fabric layered feeding structure comprises a positioning mechanism, an adsorption mechanism, a stepping mechanism and a counterweight, wherein the positioning mechanism comprises a bearing plate, a positioning pin fixed on the bearing plate, a limit baffle fixed on the edge of the bearing plate and an anti-error dial plate fixed on the bearing plate, the stepping mechanism comprises a column, a forward extension frame fixed on the column, a guide rod cylinder fixed at the front end of the forward extension frame, a pressure reducing valve fixed at the upper end of one side of the forward extension frame, and the pressure reducing valve and the guide rod cylinder are pneumatically connected, the adsorption mechanism comprises a connecting frame, four suction devices fixed on both sides of the connecting frame, and an induction switch installed at the front end of the connecting frame, the extended rod end of the guide rod cylinder is fixed on the connecting frame, driving the adsorption mechanism to move up and down, the counterweight is fixed on the column and opposite to the direction in which the forward extension frame is fixed, the lower end of the column is fixed on a slide block, and the slide block is installed on a guide rail.

[0006] The beneficial effects of the present invention are:

[0007] 1. When the absorber absorbs two pieces of fabric or absorbs one piece of fabric and sticks to part of the fabric that has not been absorbed, it will contact the anti-error pick and use the impact force at the moment of contact to peel off the sticky part of the second piece of fabric or the unabsorbed fabric from the absorbed first piece of fabric, so that the second piece of fabric or the unabsorbed fabric falls to the position before absorption, preparing for the next absorption cycle.

[0008] 2. As the fabric on the carrier plate is reduced layer by layer, the height of each adsorption of the fabric will gradually decrease. Fabric can also be added during the production process, so the height of each adsorption cannot be determined. In order to adapt to the uncertain height, a combination of a guide rod cylinder and a pressure reducing valve is adopted. After each time the guide rod cylinder descends for a certain period of time, the pressure reducing valve is used to reduce the pressure of the adsorption mechanism driven by the guide rod cylinder on the fabric, ensuring the effect of the adsorption mechanism driven by the guide rod cylinder to adsorb the fabric, which can adapt to changes in different heights.

[0009] 3. Since the adsorption structure exerts a large pressure on the fabric, the stacked fabrics on the supporting plate are under pressure, and the adhesion between the fabrics will be particularly serious, which will greatly affect the effect of adsorbing the fabrics. Therefore, a pressure reducing valve is used to reduce the pressure to achieve a good adsorption effect.

[0010] 4. The counterweight ensures that the structure is evenly stressed when statically loaded, improves the walking accuracy of the structure, and increases the service life of the structure.

[0011] In summary, the PET fabric layered feeding structure can be applied to the production of injection molded parts and components. The inlay materials and process requirements used in the inlay injection molding manufacturing process can be provided by the structure as a single-layer fabric material, further realizing a fully automatic inlay injection molding process with high repetition accuracy, low cost, and simple repair and maintenance.

[0018] like Figure 1-3 The PET fabric layered feeding structure shown in the figure includes a positioning mechanism, an adsorption mechanism, a stepping mechanism and a counterweight 40, wherein the positioning mechanism includes a carrier plate 10, a positioning pin 11 fixed on the carrier plate 10, a limit baffle 13 fixed on the edge of the carrier plate 10 and an anti-error plate 13 fixed on the carrier plate 10, and the stepping mechanism includes a column 20, a front extension frame 21 fixed on the column 20, a guide rod cylinder 23 fixed at the front end of the front extension frame 21, and a reducing rod 23 fixed at the upper end of one side of the front extension frame 21. The pressure relief valve 32, the pressure relief valve 32 and the guide rod cylinder 23 are pneumatically connected. The adsorption mechanism includes a connecting frame 30, four suction devices 32 fixed on both sides of the connecting frame 30, and an induction switch 31 installed at the front end of the connecting frame 30. The extended rod end of the guide rod cylinder 23 is fixed on the connecting frame 30, driving the adsorption mechanism to move up and down. The counterweight 40 is fixed on the column 20 and opposite to the direction in which the front extension frame 21 is fixed. The lower end of the column 20 is fixed on the slider 3, and the slider 3 is installed on the guide rail 2. The lower part of the column 20 is connected to the rodless cylinder 1 through a connecting plate, and the rodless cylinder 1 drives the slider 3 fixed under the column 20 to move on the guide rail 2.

[0019] The anti-error-shifting plate 13 includes a vertical piece 131 and a horizontal piece 130 . The vertical piece 131 is fixed on the supporting plate 10 . The horizontal piece 130 is fixed on the vertical piece 131 , parallel to the supporting plate 10 , and in contact with the upper surface of the fabric 12 in the working state.

[0020] Working process:

[0021] The operator puts the fabric 12 into the positioning pin 11, and the position of the fabric 12 on the carrier plate 10 is limited by the position of the limit plate 13 to determine the position; the total height of the fabric 12 stacked on the carrier plate 10 cannot be higher than the lowest end of the cross piece 130 of the anti-error pick 13, otherwise the anti-error pick will fail; after starting the device, when the device receives a signal instruction, it first determines whether there is fabric 12 in the measuring range through the sensor switch 31. When there is no fabric 12, the extended rod of the guide rod cylinder 23 drives the adsorption mechanism to descend, and stops descending after the sensor switch 31 detects the fabric 12, and the four absorbers 32 are turned on to absorb the fabric 12; the extended rod of the guide rod cylinder 23 drives the adsorption mechanism to rise slowly, and when passing through the cross piece 130 of the anti-error pick 13, it can block other fabrics brought up under the fabric 12 adsorbed by the absorber 32, so that it falls back to its original position.

[0022] After the extension rod of the guide rod cylinder 23 is retracted to its original position, the entire device can move horizontally along the guide rail 2 under the push of the rodless cylinder 1, and the counterweight 40 can balance the weight on one side of the front extension frame 21 to ensure the smooth operation of the entire device.

[0023] The whole device moves to the position where the fabric is placed, releasing the fabric for use by other tooling.

[0024] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
