Description

Technical Field

[0001] This invention relates to the technical field of garment processing, and in particular to an automatic sewing device and method for ear loops on pharmaceutical work clothes. Background Technology

[0002] Ear loops are decorative or functional face loops that are made separately and sewn onto clothing. Sewing ear loops onto pharmaceutical work clothes can increase the functionality of the clothing. When working in the pharmaceutical industry, it is necessary to wear not only pharmaceutical work clothes but also masks. By sewing circular ear loops onto the pharmaceutical work clothes, the mask can be hung on the circular ear loops after wearing the work clothes, thus greatly avoiding the marks caused by wearing masks for a long time.

[0003] These ear loops typically consist of a circular ear loop clip and an ear loop covering fabric. Before sewing, the covering fabric needs to be wrapped around the clip, then the entire loop is flattened before being sewn onto the pharmaceutical work uniform. However, currently, ear loop sewing is almost entirely done manually, which is not only inefficient and inconsistent in quality, but also puts the operator's hands close to the reciprocating needle during sewing. Given the small, circular shape of the ear loop, even slight carelessness can lead to injury. Summary of the Invention

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this invention are only for explaining this invention and are not intended to limit this invention.

[0022] Example 1, as Figures 1 to 4 As shown, an automatic sewing device for ear loops in pharmaceutical work clothes includes a workbench, a clamping plate assembly, a sewing machine 2, and a movement control assembly. The sewing machine 2 is fixed to the upper surface of the workbench 1. The movement control assembly is used to control the planar movement of the clamping plate assembly on the workbench 1. The clamping plate assembly includes a first clamping plate 4 and a second clamping plate 6. One end of the first clamping plate 4 is fixed to the movement control assembly, and the other end of the first clamping plate 4 is hinged to the second clamping plate 6. The second clamping plate 6 has a plurality of ear loop fastener receiving holes 601. Two movable clamping plates 7 are slidably arranged at the ear loop fastener receiving holes 601. The movable clamping plates 7 have semi-circular notches 701. The ear loop fastener receiving holes 601 are stepped holes, and the larger diameter of the ear loop fastener receiving holes 601 is larger than that of the semi-circular notches 701.

[0023] When attaching the ear loop, pull open the two movable clamps 7, wrap the ear loop covering fabric around the ear loop fastener, and place it in the large hole of the ear loop fastener receiving hole 601. Then close the two movable clamps 7, clamping the ear loop onto the second clamp 6. Next, place the work clothes on the first clamp 4, and flip the second clamp 6 so that it is flush with the first clamp 4. Align the ear loop on the second clamp 6 with the area of ​​the work clothes to be sewn. Under the pressure of the second clamp 6 and the first clamp 4, the position of the work clothes and the ear loop remains fixed when the clamp assembly moves. Then, move the ear loop under the sewing needle of the sewing machine 2 through the movement control component. The sewing of the sewing needle, in conjunction with the circular motion of the movement control component, completes the automatic sewing between the ear loop and the work clothes. The sewing operation is simple and fast, greatly avoiding close contact between the operator and the sewing needle, thus improving safety.

[0024] In this embodiment, the first clamping plate 4 is provided with a positioning hole 401. When the second clamping plate 6 is flipped to fit with the first clamping plate 4, the positioning hole 401 is aligned with the ear loop fastener receiving hole 601. The opening of the positioning hole 401 ensures that the sewing machine 2 can work normally during sewing without being blocked by the first clamping plate 4. At the same time, the first clamping plate 4 can also be used as a position reference for placing work clothes. After aligning the sewing position of the work clothes with the first clamping plate 4, the work clothes can be placed quickly.

[0025] Advantageously, the movable clamp 7 is provided with anti-slip texture 702. When the movable clamp 7 is opened or closed by hand, the anti-slip texture 702 can effectively increase the friction when the hand contacts it, making it easier for the movable clamp 7 to slide.

[0026] In this embodiment, the motion control component includes a first servo linear guide slide 3 and a second servo linear guide slide 8. Two second servo linear guide slides 8 are provided at both ends of the first servo linear guide slide 3. The first servo linear guide slide 3 and the second servo linear guide slides 8 are perpendicular to each other. The guide rail portion of the second servo linear guide slide 8 is fixed to the guide rail portion of the first servo linear guide slide 3. The slide portion of the second servo linear guide slide 8 is fixed to the first servo linear guide slide 3 via a connecting plate 9. The movement of the first servo linear guide slide 3 is controlled by the second servo linear guide slide 8. The clamping plate assembly is fixed to the slide portion of the first servo linear guide slide 3. The first clamping plate 4 is fixed to the slide portion of the first servo linear guide slide 3 via a connecting platform 5. The simultaneous movement of the first servo linear guide slide 3 and the second servo linear guide slide 8 enables the clamping plate assembly to perform a circular motion on the workbench 1, thereby sewing the circular loop onto the work clothes.

[0027] Example 2, as Figures 3 to 10 As shown, this embodiment, based on Embodiment 1, further provides a moving material picking mechanism, a flipping control mechanism, a magnetic fixing mechanism, and an opening and closing control mechanism. Through the above mechanisms, fully automatic feeding and sewing of the ear loops are realized. The moving material picking mechanism is used to automatically pick up the ear loop covering fabric and the ear loop fastener. The opening and closing control mechanism is used to control the two movable clamping plates 7 on both sides of the ear loop fastener receiving hole 601 to automatically open and close. The opening and closing control mechanism and the moving material picking mechanism cooperate with each other to complete the clamping operation of the ear loop on the clamping plate assembly.

[0028] In this embodiment, the moving material handling mechanism includes a third servo linear guide slide 11 fixed on the worktable 1 and a driver 12 fixed on the slide portion of the third servo linear guide slide 11. The driver 12 can control the hollow spline threaded screw 13 to complete lifting and rotation movements. A loop material handling mechanism 16 is fixed below the hollow spline threaded screw 13, which automatically handles the loop wrapping fabric and loop fasteners. The hollow spline threaded screw 13 has a hollow internal structure, and a negative pressure adsorption device is connected to the top of the hollow spline threaded screw 13. The bottom end of the spline threaded screw 13 is an adsorption port for adsorbing ear loop clips. The ear loop picking mechanism 16 includes a spiral support 31 fixed at the adsorption port, an annular suction cup 29 slidably disposed at the bottom end of the hollow spline threaded screw 13, and a lifting control mechanism fixed on the hollow spline threaded screw 13 to control the lifting and lowering of the hollow spline threaded screw 13. The annular suction cup 29 has an annular cavity, and an annular opening is formed below the annular cavity. The adsorption port is used to pick up ear loop clips, and the annular opening is used to pick up ear loop wraps. The spiral support 31 is used to support the ear loop clips to prevent them from bending.

[0029] Advantageously, the third servo linear guide slide 11 is raised and fixed on the worktable 1 by the support column 17, which facilitates the second clamping plate 6 to complete the flipping.

[0030] In this embodiment, the spiral support 31 includes a planar spiral portion 3101 and an arc portion 3102. The planar spiral portion 3101 and the arc portion 3102 are connected and fixed. During material handling, the lower end of the hollow spline threaded screw 13 first picks up the ear loop fastener. After picking up, the ear loop picking mechanism 16 moves above the ear loop covering fabric, and the lifting control mechanism controls the annular suction cup 29 to descend. A side wall hole is provided on the side wall of the lower end of the hollow spline threaded screw 13. 1301, when the annular suction cup 29 descends to the same height as the suction port, the connecting hole 2901 on the annular suction cup 29 aligns with the side wall hole 1301. The annular opening on the annular suction cup 29 suctions a piece of ear loop fabric. Then, the movable clamp 7 is opened, and the ear loop picking mechanism 16 moves directly above the ear loop fastener receiving hole 601. The ear loop picking mechanism 16 descends, pressing the ear loop fastener into the ear loop fastener receiving hole 601. The annular suction cup 29 is raised, and then the two movable clamps 7 are closed to wrap the edge of the ear loop covering around the ear loop fastener. The spiral support 31 provides both compression and support to the ear loop fastener when the two movable clamps 7 are closed, preventing both movement and bending of the ear loop fastener by the moving clamps 7. The spiral support 31 is then rotated and raised. The arc-shaped portion 3102 of the spiral support 31 ensures the ear loop fastener remains circular, preventing... The ear loop fastener is bent into other shapes by the sliding movable clamp 7. The planar spiral part 3101 allows the spiral support 31 to be smoothly pulled out from under the movable clamp 7 after the movable clamp 7 is closed by rotating and lifting the spiral support 31. After the spiral support 31 is pulled out from the movable clamp 7, rotating and lowering the spiral support 31 again can flatten the edge of the ear loop covering fabric and attach it to the ear loop fastener in a spiral shape, ultimately forming a sheet-like ear loop. The spiral support 31 not only provides support and stability for the ear loop fastener but can also be easily removed from the closed movable clamp 7. It can also be used to press and flatten the ear loop. The structure is simple but has multiple functions.

[0031] Advantageously, a first barrier net 30 is fixed at the suction port, and a second barrier net 32 ​​is fixed at the annular opening of the annular suction cup 29. The first barrier net 30 and the second barrier net 32 ​​can effectively prevent the ear loop clips and ear loop wrapping from being sucked into the ear loop feeding mechanism 16.

[0032] It should be noted that the connection structure between the driver 12 and the hollow spline screw 13 can adopt a ball screw spline transmission structure. The driver 12 is equipped with a spline sleeve, a threaded sleeve, and two control motors that control the rotation of the spline sleeve or the thread gauge sleeve. By controlling the rotation of the spline sleeve and the thread gauge sleeve, the lifting, rotation, and simultaneous compound motion of the hollow spline screw 13 can be completed. The specific structure is existing technology and is only explained here without limitation.

[0033] In this embodiment, the lifting control mechanism includes a lifting motor 26, a drive gear 27 fixed on the motor shaft of the lifting motor 26, and a rack 28 with one end fixedly connected to the annular suction cup 29. The body of the lifting motor 26 is fixed to the hollow spline screw 13. The drive gear 27 meshes with the rack 28. The lifting motor 26 controls the rotation of the drive gear 27, which drives the rack 28 to rise and fall. Furthermore, the rack 28 controls the rise and fall of the annular suction cup 29 fixedly connected to it.

[0034] In this embodiment, the flipping control mechanism includes an arc-shaped housing 22 and an arc-shaped telescopic rod 23 disposed within the arc-shaped housing 22. The arc-shaped housing 22 is fixed on the worktable 1. An end fixing plate 24 is fixed to the top of the arc-shaped telescopic rod 23, and an adsorption magnet 25 is hinged to the end fixing plate 24. A flipping attraction magnet (not shown in the figure) is fixed on the second clamping plate 6. When the second clamping plate 6 moves, the flipping attraction magnet on the second clamping plate 6 moves together. When the flipping attraction magnet moves above the adsorption magnet 25, the flipping attraction magnet and the adsorption magnet 25 attract and fix each other, thereby driving the second clamping plate through the adsorption magnet 25. 6. The flipping motion: The arc telescopic rod 23 includes at least three arc-shaped telescopic rods, which are interlocked to ensure that the extension and retraction of the arc telescopic rod 23 can flip the second clamping plate 6 by 180 degrees, completing the stacking and unfolding of the second clamping plate 6. The arc shell 22 has an inner cavity 2201 at one end away from the adsorption magnet 25. An air pump is connected to the inner cavity 2201. By pumping or sucking air into the inner cavity 2201, the extension and retraction of the arc telescopic rod 23 is controlled, thereby completing the flipping control of the second clamping plate 6. The second clamping plate 6 and the first clamping plate 4 are hinged through the flexible connecting piece 18, so that the second clamping plate 6 can be completely flat on the worktable 1.

[0035] In this embodiment, the magnetic fixing mechanism includes a first positioning electromagnet 19 and a second positioning electromagnet 20. Both the first positioning electromagnet 19 and the second positioning electromagnet 20 are fixed on the worktable 1. A plurality of first positioning magnets are fixed on the first clamping plate 4, and a plurality of second positioning magnets (not shown in the figure) are fixed on the second clamping plate 6. The first positioning magnets can be moved above the first positioning electromagnet 19 and aligned with it by the movement control component. After alignment, flipping the second clamping plate 6 can align the second positioning magnets with the second positioning electromagnet 20. Thus, the attraction between the first positioning electromagnet 19 and the second positioning electromagnet 20 can stably fix the first clamping plate 4 and the second clamping plate 6 on the worktable 1, ensuring that the ear loop fastener receiving hole 601 on the second clamping plate 6 is accurately in the feeding position and will not easily slip.

[0036] In this embodiment, the opening and closing control mechanism includes a strip coil drive bar 21 and a connecting bar 10. A strip-shaped limiting groove is provided on the second clamping plate 6, and the connecting bar 10 is slidably disposed within this limiting groove. The connecting bar 10 is fixed to the movable clamping plate 7. Multiple permanent magnets 1001 are evenly arranged on the connecting bar 10, with adjacent permanent magnets 1001 having opposite magnetic poles. Multiple drive coils 2101 are fixed on the strip coil drive bar 21, and these drive coils 2101 are evenly arranged on the strip coil drive bar 21. By controlling the change in the magnetic field of each drive coil 2101, the sliding of the connecting bar 10 is controlled, thereby controlling the movement of the movable clamping plate 7. After the movement control component controls the first clamping plate 4 to move to align the first positioning magnet on the first clamping plate 4 with the first positioning electromagnet 19 fixed on the worktable, the first positioning electromagnet 19 is energized to attract the first positioning magnet, thereby fixing the first clamping plate 4. (Reference) Figure 7 The arc-shaped telescopic rod 23 in the flipping control mechanism extends, and the adsorption magnet 25 fixed on the arc-shaped telescopic rod 23 attracts and fixes with the flipping attraction magnet fixed on the second clamping plate 6, thereby driving the second clamping plate 6 to flip. After the second clamping plate 6 flips, the second positioning magnet fixed on the second clamping plate 6 aligns with the second positioning electromagnet 20, and the second clamping plate 6 is fixed by the second positioning electromagnet 20. The connecting strip 10 is located directly above the strip coil drive strip 21. (Reference) Figure 8 Multiple permanent magnets 1001 with opposite magnetic poles are fixed on the connecting strip 10. A greater number of drive coils 2101 than the permanent magnets 1001 are fixed on the strip-shaped coil drive strip 21. The magnetic pole direction of the drive coils 2101 is controllable, such as... Figure 8In this figure, the magnetic pole of the drive coil 2101 to the left of the topmost permanent magnet 1001 is N / S, the magnetic pole of the drive coil 2101 below the top of ...

[0037] In this embodiment, the workbench 1 is fixedly provided with an ear loop fastener stacking position 14 and an ear loop covering fabric stacking position 15. The ear loop fastener stacking position 14 is used to stack ear loop fasteners, and the ear loop covering fabric stacking position 15 is used to stack ear loop covering fabrics. After the adjustment of the moving material picking mechanism is completed, when the ear loop fasteners or ear loop covering fabrics on the workbench 1 are used up, it is only necessary to replenish the material at the ear loop fastener stacking position 14 and the ear loop covering fabric stacking position 15 in a timely manner. This can accurately ensure that the ear loop fasteners picked up by the ear loop picking mechanism 16 are aligned with the spiral support body 31, reducing the difficulty of adjustment before each material loading.

[0038] Example 3, based on Example 2, further provides an automatic sewing method for ear loops of pharmaceutical work clothes, including the following sewing steps: S1. Ear loop material picking: The ear loop clip is picked up through the suction port at the bottom of the hollow spline threaded screw 13, and then the ear loop covering is picked up through the annular opening on the annular suction cup 29, thus completing the automatic material picking of the ear loop.

[0039] S2. Ear loop fastening: After material handling, the ear loop material handling mechanism 16 moves the ear loop fastening piece and ear loop covering fabric to above the ear loop fastening piece receiving hole 601. The movable clamping plate 7 is opened by the opening and closing control mechanism, and the ear loop material handling mechanism 16 lowers the ear loop fastening piece and ear loop covering fabric into the ear loop fastening piece receiving hole 601. The annular suction cup 29 is raised to control the movable clamping plate 7 to close, and the spiral support body 31 is rotated and raised to remove the spiral support body 31 from the movable clamping plate 7. Then, the spiral support body 31 is rotated and lowered to press the ear loop covering fabric tightly, thus completing the ear loop fastening.

[0040] S3. Loading: Place part or all of the work clothes to be sewn at the positioning hole 401 on the first clamping plate 4, and flip the second clamping plate 6 to clamp it.

[0041] S4. Sewing: The moving control component controls the movement of the clamping plate assembly so that the loop on the second clamping plate 6 moves below the sewing machine 2. The sewing machine 2 is controlled to sew, and the second clamping plate 6 is controlled to draw a circle to complete the sewing of the loop to the work clothes.

[0042] S5. Unloading: The moving control component controls the clamping plate assembly to the unfoldable position, and then the flipping control mechanism controls the opening of the clamping plate assembly. Finally, the robotic arm removes the work clothes.
