Abstract
Description
Technical Field
[0001] This application relates to the field of jig technology, specifically to a jig for a plastic patch. Background Technology
[0002] In manufacturing, plastic patches are widely used on product surfaces as important appearance or functional components. For example, plastic patches are attached to bio-based PE substrates (such as polyethylene materials made from renewable biomass like sugarcane and corn through fermentation and polymerization processes) to serve identification and decorative purposes.
[0003] Currently, the common plastic patch assembly processes in the industry mainly rely on two methods: manual application and tooling application.
[0004] When applying the plastic patch manually, the operator aligns it directly with the area on the product to be covered, thus assembling the patch. However, this method has significant drawbacks: for mass production, manual operation is slow and inefficient; and direct contact between fingers and the adhesive or surface of the patch can easily leave fingerprints, dust, or scratches on the plastic patch.
[0005] To improve application efficiency and avoid damaging the plastic patches, fixture application is currently the most common method. In fixture application, the plastic patch is first placed in the mounting slot of the fixture. The fixture is then moved to align the patch with the area on the product to be covered. A pusher on the fixture then moves the patch out of the mounting slot and onto the product. However, this method suffers from poor fixture versatility: some larger plastic patches cannot fit into the mounting slot, requiring the manufacture of fixtures of the appropriate size to accommodate the patch shape, thus increasing costs.

Detailed Implementation
[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] See Figures 1-4 In this embodiment, a fixture for plastic patches is proposed, including a housing 100, on which a movable arm 200 and a driving device 300 are provided.
[0026] like Figure 4 As shown, there are multiple movable arms 200, which are arranged in a circular array. The movable arms 200 are slidably disposed within the receiving cavity 101 of the housing 100.
[0027] In this embodiment, there are four movable arms 200. In other embodiments, the number of movable arms 200 can be two, three, or five. Specifically, the number of movable arms 200 needs to be controlled within a certain range. If the number is too large, it will not only increase the manufacturing cost, but also lead to an increase in the size and weight of the fixture.
[0028] The receiving cavity 101 is cylindrical, and the sliding direction of the movable arm 200 relative to the housing 100 corresponds to the radial direction of the receiving cavity 101. Specifically, the sliding direction of each movable arm 200 relative to the housing 100 is consistent with the radial direction of the receiving cavity 101.
[0029] The drive unit 300 is used to drive each movable arm 200 to extend or retract synchronously into the receiving cavity 101. By driving all movable arms 200 synchronously through the drive unit 300, the manufacturing cost of the fixture is reduced, as well as the size and weight of the fixture, while also improving the ease of operation of the movable arms 200.
[0030] like Figure 5 As shown, the movable arm 200 includes a mounting portion 210, which is located on one side of the movable arm 200. The mounting portion 210 is located outside the receiving cavity 101.
[0031] The mounting section 210 is equipped with a telescopic rod 400, and the base at the end of the telescopic rod 400 is fixedly connected to the mounting section 210 by means of screws or other methods. The telescopic rods 400 on each movable arm 200 are arranged in parallel.
[0032] The telescopic rod 400 extends in a direction parallel to the depth of the receiving cavity 101. One end of the telescopic rod 400 is fixedly connected to the mounting part 210, and the other end is equipped with a vacuum nozzle 500. The vacuum nozzle 500 is used to adsorb plastic patches. (Refer to...) Figure 1 The telescopic rod 400 extends in the direction parallel to the direction indicated by arrow x.
[0033] The vacuum nozzle 500 corresponds one-to-one with the movable arm 200. Since there are four movable arms 200, there are also four vacuum nozzles 500. This allows for the adaptation of plastic patches of different sizes, enabling the fixture to stably fix the plastic patches and ensuring that subsequent patch application can be completed smoothly.
[0034] Before fixing the plastic patch, the fixture adjusts the synchronous movement of each movable arm 200 (i.e., synchronously extending or retracting the receiving cavity 101 of the housing 100) based on the size of the plastic patch by the drive device 300. This increases or decreases the distance between each vacuum nozzle 500 so that the distance between the vacuum nozzles 500 can be adapted to the size of the plastic patch, ensuring that each nozzle can be aligned and adsorb the plastic patch. In this way, the fixture can fix the plastic patch.
[0035] Some plastic patches have a flat surface. When the fixture fixes these plastic patches, all telescopic rods 400 are controlled to the same length, so that the adsorption parts of each vacuum nozzle 500 can be ensured to be on the same plane, thereby fixing the plastic patch. Some plastic patches have raised or recessed structures on their surface (for example, the surface of the plastic patch has a three-dimensional texture). In this case, by adjusting the length of the corresponding telescopic rod 400, the position of the corresponding vacuum nozzle 500 is adjusted so that the vacuum nozzle 500 can fit with the raised or recessed structure on the surface of the plastic patch, thereby ensuring that each vacuum nozzle 500 can be adsorbed on the corresponding position of the plastic patch, thereby fixing the plastic patch.
[0036] Therefore, it can be seen that the fixture for this plastic patch can effectively adapt to plastic patches of different sizes and irregular shapes, and has good versatility.
[0037] like Figure 3 As shown, the drive unit 300 includes a transmission component 310, a gear 320, and a power unit 330.
[0038] The transmission component 310 is rotatably disposed within the receiving cavity 101.
[0039] like Figure 6 As shown, the transmission component 310 includes an end cap 311 and an internal gear ring 312. The end cap 311 and the internal gear ring 312 are integrally formed, with the end cap 311 positioned on one side of the internal gear ring 312 along its thickness direction. The end cap 311 is positioned opposite the bottom surface of the receiving cavity 101, and the internal gear ring 312 is coaxially arranged with the receiving cavity 101, with a clearance fit between the internal gear ring 312 and the receiving cavity 101.
[0040] Gear 320 is located within the receiving cavity 101 and is rotatably connected to the housing 100. Gear 320 meshes with the internal gear ring 312.
[0041] Gear 320 corresponds one-to-one with movable arm 200. For example... Figure 5 As shown, the movable arm 200 includes a rack portion 220. A gear 320 meshes with the corresponding rack portion 220 of the movable arm 200.
[0042] In this embodiment, the drive device 300 includes a first motor. The main body of the first motor is mounted outside the receiving cavity 101; the output shaft of the first motor is inserted into the receiving cavity 101. Figure 6 As shown, the end cover 311 is provided with a mounting hole 313, into which the output shaft of the first motor is inserted. Specifically, the output shaft of the first motor is fixedly connected to the mounting hole 313 via an interference fit.
[0043] Reference Figure 3 The housing 100 includes a main housing 110 and a cover 120, which are detachably connected. Specifically, the main housing 110 and the cover 120 are detachably connected by screws.
[0044] The receiving cavity 101 is disposed inside the main shell 110, and the shell cover 120 is used to close the opening of the receiving cavity 101 on one side in the depth direction.
[0045] like Figure 7 As shown, the side of the main shell 110 is provided with an extension 111, which corresponds to the movable arm 200.
[0046] An extension 111 has a guide groove 112, which communicates with the receiving cavity 101. The movable arm 200 is slidably inserted into the guide groove 112 of the corresponding extension 111, wherein, referring to… Figure 4 Both ends of the movable arm 200 extend beyond the guide groove 112.
[0047] When the movable arm 200 slides relative to the housing 100, the guide groove 112 is used to guide the corresponding movable arm 200. The guide groove 112 is arranged radially along the receiving cavity 101. Under the constraint of the guide groove 112, the sliding direction of the movable arm 200 relative to the housing 100 can be restricted and guided, ensuring that the movable arm 200 slides more smoothly.
[0048] like Figure 8As shown, the cover 120 is provided with a cover portion 121, which corresponds one-to-one with the extension portion 111. The cover portion 121 is used to cover the guide groove 112 of the corresponding extension portion 111 to close the opening of the guide groove 112 on one side in the depth direction. The receiving cavity 101 and the guide groove 112 are in the same depth direction, and their openings are both located on the same side of the main shell 110.
[0049] like Figure 5 As shown, the movable arm 200 has a protrusion 230 at one end located inside the receiving cavity 101.
[0050] like Figure 8 As shown, the cover portion 121 includes a limiting portion 122 corresponding to the protrusion 230. In this embodiment, the limiting portion 122 is the sidewall of the cover portion 121 facing the receiving cavity 101.
[0051] The limiting part 122 is used to limit the maximum length of the movable arm 200 that can extend out of the receiving cavity 101, wherein the maximum length of the movable arm 200 that can extend out of the receiving cavity 101 is a preset length. When the length of the movable arm 200 extending out of the receiving cavity 101 reaches the preset length, the protrusion 230 abuts against the corresponding limiting part 122.
[0052] The limiting part 122 limits the maximum length that the movable arm 200 can extend outside the receiving cavity 101, thus preventing production accidents caused by the movable arm 200 colliding with the housing 100 due to operational errors or other reasons.
[0053] like Figure 3 As shown, the cover 120 is provided with an adapter hole 123, which corresponds one-to-one with the gear 320; the gear 320 is provided with a connecting shaft 321, which is coaxially arranged with the gear 320. The connecting shaft 321 of the gear 320 is rotatably inserted into the corresponding adapter hole 123.
[0054] When the power unit 330 is started, the transmission member 310 will rotate under the action of the power unit 330. As the transmission member 310 rotates, the internal gear ring 312 of the transmission member 310 will drive all gears 320 to rotate in the same direction (clockwise or counterclockwise). The gears 320 act on the rack portion 220 of the corresponding movable arm 200, thereby causing the movable arm 200 to translate radially along the receiving cavity 101, so that the movable arm 200 extends or retracts into the receiving cavity 101.
[0055] The longer the movable arm 200 extends into the receiving cavity 101, the greater the distance between the vacuum nozzles 500 on adjacent movable arms 200, thus accommodating larger plastic patches; conversely, the shorter the length of the movable arm 200 extending into the receiving cavity 101, the smaller the distance between the vacuum nozzles 500 on adjacent movable arms 200, thus accommodating smaller plastic patches.
[0056] like Figure 9 and Figure 10 As shown, a universal adjustment mechanism is provided between the telescopic rod 400 and the vacuum nozzle 500. The universal adjustment mechanism is used to control the rotation of the vacuum nozzle 500 to adjust the position of the vacuum nozzle 500.
[0057] Reference Figure 11 Some plastic patches may have a slope 10 formed by the three-dimensional structure on their surface, which may cause some vacuum nozzles 500 to be unable to be aligned and adsorbed. In this case, the corresponding vacuum nozzles 500 can be adjusted by the universal adjustment mechanism so that the vacuum nozzles 500 can be aligned with the slope 10 and complete the adsorption.
[0058] The universal adjustment mechanism includes a first adjustment module 600 and a second adjustment module 700. The first adjustment module 600 is fixedly connected to the telescopic rod 400, the second adjustment module 700 is connected to the first adjustment module 600, and the vacuum nozzle 500 is connected to the second adjustment module 700.
[0059] The first adjustment module 600 drives the second adjustment module 700 to rotate. Driven by the first adjustment module 600, the rotation axis of the second adjustment module 700 is parallel to the extension / retraction direction of the telescopic rod 400, wherein, referring to… Figure 9 The rotation axis of the second adjustment module 700 is parallel to the direction indicated by arrow x.
[0060] Since the vacuum nozzle 500 is connected to the second adjustment module 700, when the first adjustment module 600 drives the second adjustment module 700 to rotate, the vacuum nozzle 500 will also rotate with the second adjustment module 700.
[0061] The second adjustment module 700 is used to drive the vacuum nozzle 500 to rotate. Driven by the second adjustment module 700, the rotation axis of the vacuum nozzle 500 is perpendicular to the extension / retraction direction of the telescopic rod 400, wherein, referring to… Figure 9 The rotation axis of the vacuum nozzle 500 is parallel to the direction indicated by arrow y.
[0062] In the initial state, the vacuum nozzle 500 and the telescopic rod 400 are coaxial. When it is necessary to avoid unsuitable positions on the plastic patch that are not suitable for adsorption, the vacuum nozzle 500 can be rotated by the second adjustment module 700 to make the vacuum nozzle 500 biased towards the inclined surface 10 to be adsorbed. If the vacuum nozzle 500 still cannot be accurately aligned with the inclined surface 10 after adjustment by the second adjustment module 700, the second adjustment module 700 can be rotated by the first adjustment module 600 to further adjust the orientation of the vacuum nozzle 500 and ensure that the vacuum nozzle 500 can be accurately aligned with the inclined surface 10 to be adsorbed.
[0063] like Figure 12 As shown, the first adjustment module 600 includes a second motor 610, a sleeve 620, and a connecting plate 630.
[0064] The main body of the second motor 610 is fixedly connected to the sleeve 620, wherein the sleeve 620 is fitted onto and fixed to the telescopic rod 400.
[0065] The drive shaft of the second motor 610 is fixedly connected to the connecting plate 630. The second adjustment module 700 and the connecting plate 630 can be fixedly connected by screws or other means.
[0066] like Figure 13 and Figure 14 As shown, the second adjustment module 700 includes a servo motor 710 and a first bracket 720. The servo motor 710 is connected to the vacuum nozzle 500.
[0067] The structure of the servo motor 710 can refer to existing technology. The servo motor 710 can more accurately adjust the rotation angle of the vacuum nozzle 500 so that the vacuum nozzle 500 can be more accurately aligned with the inclined surface 10 to be adsorbed.
[0068] The servo motor 710 includes a first connecting part 711 and a second connecting part 712, which are respectively located on both sides of the servo motor 710 along its length, wherein the length of the servo motor 710 is parallel to the extension and retraction direction of the telescopic rod 400.
[0069] The first support 720 includes a first component 721, a second component 722, and a third component 723 connected in sequence. The first component 721 and the second component 722 are perpendicular to each other, and the second component 722 and the third component 723 are perpendicular to each other. The first component 721 and the third component 723 are parallel and opposite to each other. The first component 721 is fixedly connected to the connecting plate 630.
[0070] The first component 721 is provided with a first mounting part 7211, and the third component 723 is provided with a second mounting part 7231, wherein the first mounting part 7211 is fixedly connected to the first connecting part 711, and the second mounting part 7231 is fixedly connected to the second connecting part 712.
[0071] Furthermore, the second adjustment module 700 also includes a second bracket 730. The servo motor 710 is connected to the vacuum nozzle 500 via the second bracket 730.
[0072] The second support 730 is U-shaped and includes a base 731, a first arm 732, and a second arm 733. The first arm 732 and the second arm 733 are parallel and opposite to each other, and the first arm 732 and the second arm 733 are respectively connected to the two ends of the base 731.
[0073] In this embodiment, the first bracket 720 is an integral structure, and the second bracket 730 is also an integral structure.
[0074] The servo motor 710 is located between the first arm 732 and the second arm 733.
[0075] The second component 722 has a mounting shaft 7221 on the side away from the servo motor 710. The mounting shaft 7221 is inserted into the first insertion hole 7321 of the first support arm 732, wherein the mounting shaft 7221 and the first insertion hole 7321 are rotatably connected.
[0076] The drive shaft of the servo motor 710 is inserted into the second insertion hole 7331 of the second support arm 733, wherein the drive shaft of the servo motor 710 is fixedly connected to the second insertion hole 7331.
