Abstract

This utility model provides a one-line pull-wire conveying type applicator, including a feeding device, an applicator, and a conveying device. The conveying device includes a first pull wire, a bottom mold, a second pull wire, a product conveying mechanism, and a product positioning mechanism. The product conveying mechanism is used to move the applicator to be applied on the first pull wire to the bottom mold, and to move the applicator-applied product on the bottom mold to the second pull wire. The product positioning mechanism includes a positioning block, a side pushing mechanism, and a rear pushing mechanism. When the applicator to be applied moves on the first pull wire, the front end of the product is limited by the positioning block, the side pushing mechanism pushes the product from the side for lateral limitation, and the rear pushing mechanism rises to the rear of the product and pushes the rear end of the product for rear limitation. By positioning the product from three directions through the product positioning mechanism, the positional deviation of the product during the conveying process on the first pull wire is eliminated, the success rate of conveying to the bottom mold is improved, and the product is moved to the bottom mold by conveying, resulting in a flat bonding surface.

Description

Technical Field

[0001] This utility model relates to the field of applicator equipment technology, and in particular to an applicator machine with a single-line pull-and-transfer type. Background Technology

[0002] Currently, the traditional flat belt type auxiliary material applicator in the industry moves the product through a whole flat belt. When the product moves to the middle, it stops to apply the auxiliary material, and then continues to move after application.

[0003] For applications involving glass or composite materials, traditional flat belt-type applicator machines are ill-suited to the characteristics of these products, presenting numerous problems. These products are thin and cannot be stopped while being conveyed on a flat belt, easily resulting in positional shifts as they move along the belt. Furthermore, the bottom of the products often has decorative components such as cameras, leading to uneven placement on the flat belt and a low success rate for applicator application. Additionally, the large contact surface and high friction of the flat belt make it easy to damage the products as they move along it.

[0004] Therefore, there is an urgent need for a product applicator that is suitable for products that are brittle, thin, and have uneven bottom surfaces (such as camera decorative parts protruding from the back of a mobile phone). Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a one-line pull-type auxiliary material applicator, which can position the product from three directions through the product positioning mechanism, eliminate the positional deviation of the product during the first pull line conveying process, improve the success rate of transporting to the bottom mold, and move the product to the bottom mold by the transport method, so that the bonding surface of the product is flat.

[0006] This utility model provides a one-line pull-wire conveying auxiliary material applicator for attaching auxiliary materials to products, including a feeding device, an applicator, and a conveying device; the conveying device includes a first pull wire, a bottom mold, a second pull wire, a product conveying mechanism, and a product positioning mechanism; The product handling mechanism is used to move the product to be attached on the first pull line to the bottom mold, and to move the product with attached accessories on the bottom mold to the second pull line; the material attaching device is used to attach the material provided by the material supply device to the product to be attached on the bottom mold. The product positioning mechanism includes a positioning block, a side pushing mechanism, and a rear pushing mechanism. When the product to be attached to the auxiliary material moves on the first pull line, the front end of the product is limited by the positioning block, the side pushing mechanism pushes the product from the side to limit its side position, and the rear pushing mechanism rises to the rear of the product and pushes the rear end of the product to limit its rear position.

[0007] Furthermore, both the first pull wire and the second pull wire are round belts, and the first pull wire and the second pull wire move in the same direction. The product handling mechanism reciprocates between the first pull wire, the second pull wire, and the bottom mold.

[0008] Furthermore, the first pull wire has a feeding position at one end near the bottom mold, the bottom mold has a material attaching position, and the second pull wire has a discharging position at one end near the bottom mold.

[0009] Furthermore, the positioning stop is configured to block the front end of the product at the loading position through the first positioning, the side pushing mechanism is configured to block the side of the product at the loading position through the second positioning, and the rear pushing mechanism is configured to block the rear end of the product at the loading position through the third positioning.

[0010] Furthermore, the positioning block is suspended and fixed above the first pull line, and the side push mechanism includes a push block and a side push drive mechanism. The side push drive mechanism is used to drive the push block to abut against the side of the product. There are two side push mechanisms, which are respectively arranged on both sides of the first pull line, and abut against the two sides of the product from two directions at the same time.

[0011] Furthermore, the push mechanism is located below the first pull line. The push mechanism includes a pneumatic finger and a push drive mechanism. The push drive mechanism is used to drive the pneumatic finger to rise above the first pull line. The pneumatic finger is used to push the rear end face of the product. After the product is limited by the positioning block and the side push mechanism, the rear push drive motor drives the pneumatic finger to rise to the rear of the product, and the pneumatic finger swings to push against the rear end surface of the product.

[0012] Furthermore, the bottom mold has a contoured groove that matches the product. After the product transport mechanism moves the product onto the bottom mold, the product is embedded in the contoured groove. The bottom of the contoured groove is also provided with a suction nozzle for adsorbing and fixing the product onto the bottom mold.

[0013] Furthermore, the product handling mechanism includes a base plate, a product suction mechanism, and a first handling drive mechanism. The product suction mechanism is fixedly mounted on the base plate, and the first handling drive mechanism is used to drive the base plate and the product suction mechanism to reciprocate between the loading position, the auxiliary material application position, and the unloading position. The product suction mechanism includes a suction cup and a second transport drive mechanism. The suction cup is used to suction the bottom surface of the product. The movement direction of the second transport drive mechanism is perpendicular to the movement direction of the first transport drive mechanism. The second transport drive mechanism is used to drive the suction cup to rise and fall. When the suction cup rises, it lifts the product away from the first pull line or the bottom mold; when the suction cup descends, it places the product on the bottom mold or the second pull line.

[0014] Furthermore, there are two product suction mechanisms, both of which are fixedly mounted on the base plate; the distance between the feeding position and the attaching position is equal to the distance between the attaching position and the unloading position, and is also equal to the distance between the two product suction mechanisms. When one of the product suction mechanisms lifts the product to be attached from the first pull line, the other product suction mechanism lifts the product with the attached material from the bottom mold. When one of the product suction mechanisms lowers to place the product to be attached onto the bottom mold, the other product suction mechanism lowers to place the product with the attached material onto the second pull line.

[0015] Furthermore, there are two product positioning mechanisms, which are symmetrically arranged on the first pull line and the second pull line respectively. The two positioning blocks of the two product positioning mechanisms are close to the two ends of the bottom mold respectively. When the first pull line is the product entry end, the second pull line is the product exit end; when the first pull line is the product exit end, the second pull line is the product entry end.

[0016] In summary, this utility model embodiment can position the product from three directions through a product positioning mechanism, eliminate the positional deviation of the product during the conveying process on the first pull line, improve the success rate of transporting to the bottom mold, and move the product to the bottom mold by means of transport, resulting in a flat bonding surface of the product.

[0017] Furthermore, both the first and second pull cords are round belts, resulting in a small contact area between the product and the first and second pull cords during transportation, which greatly reduces the risk of product scratches.

[0018] Furthermore, the positioning blocks, side push mechanism, and rear push mechanism clamp the product from four directions, confining it to the loading position and correcting positional errors that occur when the product moves along the first pull line. This ensures that the product handling mechanism can accurately move the product from the loading position to the auxiliary material application position on the bottom mold each time, improving the success rate of auxiliary material application.

[0019] Furthermore, the rear-push mechanism includes pneumatic fingers and a rear-push drive mechanism. When the product is limited by the positioning block and the side-push mechanism, the rear-push drive mechanism drives the pneumatic fingers to rise to the rear of the product. The pneumatic fingers swing to push and abut against the rear end face of the product. When the product moves along the first pull line, it may bounce back after hitting the positioning block, and the front end face may not necessarily abut against the positioning block. In this case, the pneumatic fingers pushing from back to front ensure that the front end face of the product abuts against the positioning block.

[0020] Furthermore, the bottom mold has contoured grooves that match the product, and the bottom of the contoured grooves is equipped with suction nozzles to adhere the product to the bottom mold. The decorative parts on the bottom of the product are leveled, and the top surface of the product is the bonding surface. This ensures that the bonding surface is flat and level, improving the accuracy and success rate when applying auxiliary materials.

[0021] Furthermore, there are two product suction mechanisms. The distance between the loading position and the auxiliary material application position is equal to the distance between the auxiliary material application position and the unloading position, and also equal to the spacing between the two product suction mechanisms. The two product suction mechanisms work synchronously. One mechanism is dedicated to transporting the product to be applied with auxiliary materials from the loading position of the first pull line to the auxiliary material application position of the bottom mold, while the other mechanism is dedicated to transporting the product with applied auxiliary materials from the auxiliary material application position of the bottom mold to the unloading position of the second pull line, resulting in higher work efficiency.

[0022] Furthermore, there are two product positioning mechanisms, symmetrically arranged on the first pull line and the second pull line, which are suitable for production lines with different flow directions. Attached Figure Description

[0034] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0038] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0039] The following detailed explanation uses specific examples: like Figures 1 to 9 As shown, this utility model embodiment provides a one-line pull-wire conveying type auxiliary material applicator for attaching auxiliary material 110 to a product, including a feeding device 100, an applicator 200, and a conveying device 300; the conveying device 300 includes a first pull wire 310, a bottom mold 320, a second pull wire 330, a product conveying mechanism 340, and a product positioning mechanism 350; The product handling mechanism 340 is used to move the product to be attached on the first pull line 310 to the bottom mold 320, and to move the product with attached auxiliary material on the bottom mold 320 to the second pull line 330; the material attaching device 200 is used to attach the auxiliary material 110 provided by the material supply device 100 to the product to be attached on the bottom mold 320. The product positioning mechanism 350 includes a positioning block 351, a side pushing mechanism 352, and a rear pushing mechanism 353. When the product to be attached moves on the first pull line 310, the front end of the product is limited by the positioning block 351, the side pushing mechanism 352 pushes the product from the side to limit its side position, and the rear pushing mechanism 353 rises to the rear of the product and pushes the rear end of the product to limit its rear position.

[0040] In this embodiment, both the first pull wire 310 and the second pull wire 330 are round belts. The first pull wire 310 and the second pull wire 330 move in the same direction. The product handling mechanism 340 reciprocates between the first pull wire 310, the second pull wire 330 and the bottom mold 320.

[0041] Specifically, the round belt has low friction and is less likely to damage the product. The product is transported by a round belt conveyor and handling method, which is compatible with fragile, thin products and products with uneven bottom surfaces (such as the camera decoration parts protruding on the back of a mobile phone).

[0042] Specifically, the bottom mold 320 is set between the first pull line 310 and the second pull line 330. The product moves sequentially from one end of the first pull line 310 to the other end along the moving direction of the first pull line 310 and the second pull line 330. Then, it is transported from the first pull line 310 to the bottom mold 320 by the product transport mechanism 340. After the auxiliary material is applied, the product transport mechanism 340 transports the product from the bottom mold 320 to the second pull line 330. After moving from one end of the second pull line 330 to the other end, the product flows out of the single-line pull line transport auxiliary material applicator to the next process line or is collected.

[0043] In this embodiment, the first pull wire 310 has a feeding position 410 at one end near the bottom mold 320, the bottom mold 320 has an auxiliary material attaching position 420, and the second pull wire 330 has a discharging position 430 at one end near the bottom mold 320.

[0044] In this embodiment, the positioning block 351 is configured to block the front end of the product at the loading position 410 through the first positioning, the side pushing mechanism 352 is configured to block the side of the product at the loading position 410 through the second positioning, and the rear pushing mechanism 353 is configured to block the rear end of the product at the loading position 410 through the third positioning.

[0045] In this embodiment, the positioning block 351 is suspended and fixed above the first pull line 310. The side push mechanism 352 includes a push block 3521 and a side push drive mechanism 3522. The side push drive mechanism 3522 is used to drive the push block 3521 to abut against the side of the product. There are two side push mechanisms 352, which are respectively arranged on both sides of the first pull line 310, and abut against the two sides of the product from two directions at the same time.

[0046] In this embodiment, the push mechanism 353 is located below the first pull line 310. The push mechanism 353 includes a pneumatic finger 3531 and a push drive mechanism 3532. The push drive mechanism 3532 is used to drive the pneumatic finger 3531 to rise above the first pull line 310. The pneumatic finger 3531 is used to push the rear end face of the product. After the product is limited by the positioning block 351 and the side push mechanism 352, the rear push drive motor drives the pneumatic finger 3531 to rise to the rear of the product, and the pneumatic finger 3531 swings to push against the rear end surface of the product.

[0047] Specifically, the pneumatic finger 3531 works by mimicking the bending and hooking motion of a finger to push the rear end of the product, ensuring that the front end of the product abuts against the positioning block 351. This is because sometimes the front end of the product may spring back after hitting the positioning block 351; therefore, the pneumatic finger 3531 is included.

[0048] In this embodiment, a contoured groove (not shown in the figure) matching the product is provided on the bottom mold 320. After the product conveying mechanism 340 moves the product onto the bottom mold 320, the product is embedded in the contoured groove. A suction nozzle (not shown in the figure) is also provided at the bottom of the contoured groove to adsorb and fix the product onto the bottom mold 320.

[0049] Specifically, Figure 5 The image shows two product shapes. One is a flat shape on the right, with an uneven bottom surface (like the raised camera trim on a phone back cover). The other is a carrier shape on the left, similar to a tray. The triangular product is mounted on the carrier, which has triangular grooves to accommodate and hold the product. When the carrier is placed on the bottom mold 320, it is held in place by the suction nozzle of the bottom mold 320 (not shown in the image).

[0050] Specifically, the product is placed on the contour mold 320 and then the auxiliary material 110 is applied. The auxiliary material 110 and the bonding surface of the product are in a horizontal and parallel state, which improves the bonding effect.

[0051] In this embodiment, the product handling mechanism 340 includes a base plate 341, a product suction mechanism 342, and a first handling drive mechanism 343. The product suction mechanism 342 is fixedly mounted on the base plate 341, and the first handling drive mechanism 343 is used to drive the base plate 341 and the product suction mechanism 342 to reciprocate between the loading position 410, the auxiliary material application position 420, and the unloading position 430. The product suction mechanism 342 includes a suction cup 3421 and a second transport drive mechanism 3422. The suction cup 3421 is used to suction the bottom surface of the product. The moving direction of the second transport drive mechanism 3422 is perpendicular to the moving direction of the first transport drive mechanism 343. The second transport drive mechanism 3422 is used to drive the suction cup 3421 to rise and fall. When the suction cup 3421 rises, it lifts the product and moves it away from the first pull line 310 or the bottom mold 320; when the suction cup 3421 falls, it places the product on the bottom mold 320 or the second pull line 330.

[0052] In this embodiment, there are two product suction mechanisms 342, both of which are fixedly mounted on the base plate 341; the distance between the feeding position 410 and the auxiliary material application position 420 is equal to the distance between the auxiliary material application position 420 and the unloading position 430, and is also equal to the distance between the two product suction mechanisms 342. When one product suction mechanism 342 lifts the product to be attached from the first pull line 310, another product suction mechanism 342 lifts the product with the attached material from the bottom mold 320. When one product suction mechanism 342 lowers to place the product to be attached onto the bottom mold 320, another product suction mechanism 342 lowers to place the product with the attached material onto the second pull line 330.

[0053] In this embodiment, there are two product positioning mechanisms 350, which are symmetrically arranged on the first pull line 310 and the second pull line 330, respectively. The two positioning blocks 351 of the two product positioning mechanisms 350 are close to the two ends of the bottom mold 320, respectively. When the first pull line 310 is the product entry end, the second pull line 330 is the product exit end; when the first pull line 310 is the product exit end, the second pull line 330 is the product entry end.

[0054] In this embodiment, there are two feeding devices 100, which can provide two different types of auxiliary materials 110 respectively. The applicator 200 has two suction heads 210, which can pick up either the two types of auxiliary materials 110 or two of the same type of auxiliary material 110. This improves the success rate and efficiency of applicating the auxiliary materials 110.

[0055] In this embodiment, the linear guide wire conveying applicator further includes a pre-applying positioning device 510, a post-applying positioning device 520, and an applicator positioning device 530. The pre-applying positioning device 510, the post-applying positioning device 520, and the applicator positioning device 530 are all cameras.

[0056] The pre-positioning device 510 is used to take a picture of the peeling plate 120 from top to bottom and position the auxiliary material 110 on the peeling plate 120 so that the suction head 210 can pick up the auxiliary material 110 on the peeling plate 120.

[0057] After taking the auxiliary material, the positioning device 520 is used to take a picture of the suction head 210 from bottom to top, and to position the auxiliary material 110 on the suction head 210 for correction.

[0058] The material placement positioning device 530 is used to take pictures of the product on the material placement position 420 of the bottom mold 320 from top to bottom. Before the suction head 210 applies the material 110, it positions the product on the bottom mold 320 to ensure it is located on the material placement position 420. If the product's position is off, it corrects the position based on the position of the material 110 on the suction head 210 and continues applying the material 110. After the suction head 210 applies the material 110, it positions the material 110 on the product to ensure it is properly attached and determines whether the attachment is successful. If successful, it continues; if unsuccessful, it removes the failed material 110 and re-attaches a new material 110, or reports an error.

[0059] The product is fixed at the material application position 420. The camera field of view of the material application positioning device 530 is reduced, which improves the accuracy of visual recognition.

[0060] In this embodiment, the working principle is as follows: 1. The auxiliary material 110 is supplied in the form of a roll. It is peeled by two standard feeders (feeding devices 100) and supplied on the peeling plate 120.

[0061] 2. The auxiliary material 110 receiving positioning system (auxiliary material pre-positioning device 510) guides the two suction heads 210 on the material attaching robot (material attaching device 200) to take one auxiliary material 110 from each of the two feeder peeling plates 120.

[0062] 3. After the suction head 210 picks up the auxiliary material 110, it moves above the auxiliary material 110 secondary camera (the positioning device 520 after picking up the auxiliary material) to wait for the second photo.

[0063] 4. After the two auxiliary materials are picked up, the positioning devices 520 take a second photo of the two auxiliary materials 110. After taking the photo, wait for the product to be placed at the auxiliary material placement position 420 before bonding.

[0064] 5. The product is conveyed by the upstream machine on the production line or placed manually onto the feeding line (first line 310) of this machine.

[0065] 6. The first conveyor belt 310 will transfer the product to the designated waiting area (loading position 410).

[0066] 7. The product positioning mechanism 350 arranged on the first pull line 310 corrects the product position and eliminates the deviation generated during the transmission process.

[0067] 8. The product handling mechanism 340 handles the product onto the contouring base mold 320.

[0068] 9. On the contouring base mold 320, the base mold 320 holds the product by suction nozzle, and the product camera (attachment positioning device 530) takes a picture of the product. After taking the picture, wait for the auxiliary material 110 to be attached.

[0069] 10. The suction head 210 attaches the auxiliary material 110 to the product, and then moves to the feeder peeling plate to perform the next action.

[0070] 11. After the suction head 210 is removed, the product camera (patch positioning device 530) takes pictures of the patched auxiliary material 110 and the product to determine whether the patching is OK or NG.

[0071] 12. If OK is determined, proceed to the next step; if NG is determined, re-paint according to the pre-planned procedure; if NG occurs multiple times, an alarm will be triggered for manual intervention.

[0072] 13. The handling robot (product handling mechanism 340) lifts the product from the bottom mold 320 and transports it to the unloading pull line (second pull line 330). The unloading pull line (second pull line 330) then conveys the product to the downstream machine of the production line (or to a designated location for manual removal).

[0073] This completes one workflow.

[0074] In summary, this utility model embodiment can position the product from three directions through the product positioning mechanism 350, eliminate the positional deviation of the product during the conveying process on the first pull line 310, improve the success rate of transporting to the bottom mold 320, and move the product to the bottom mold 320 by means of transport, so that the product's bonding surface is flat.

[0075] Furthermore, both the first pull cord 310 and the second pull cord 330 are round belts, resulting in a small contact area between the product and the first pull cord 310 and the second pull cord 330 during product transportation, which greatly reduces the risk of product abrasion.

[0076] Furthermore, the positioning stop 351, the side push mechanism 352, and the rear push mechanism 353 respectively abut and clamp the product from four directions, restricting the product to the loading position 410 and correcting the positional error caused when the product moves on the first pull line 310. In this way, the product handling mechanism 340 can accurately move the product from the loading position 410 to the auxiliary material application position 420 on the bottom mold 320 each time, improving the success rate of auxiliary material application 110.

[0077] Furthermore, the rear push mechanism 353 includes a pneumatic finger 3531 and a rear push drive mechanism 3532. When the product is limited by the positioning block 351 and the side push mechanism 352, the rear push drive mechanism drives the pneumatic finger 3531 to rise to the rear of the product. The pneumatic finger 3531 swings to push against the rear end face of the product. When the product moves on the first pull line 310, it may bounce back after hitting the positioning block 351, and the front end face may not necessarily abut against the positioning block 351. At this time, the pneumatic finger 3531 pushes from back to front to ensure that the front end face of the product abuts against the positioning block 351.

[0078] Furthermore, the bottom mold 320 has a contoured groove that matches the product, and the bottom of the contoured groove is equipped with a suction nozzle for adsorbing and fixing the product onto the bottom mold 320. The decorative parts on the bottom surface of the product are leveled, and the upper surface of the product is the bonding surface. This ensures that the bonding surface is flat and level, improving the accuracy and success rate when applying the auxiliary material 110.

[0079] Furthermore, there are two product suction mechanisms 342. The distance between the loading position 410 and the auxiliary material application position 420 is equal to the distance between the auxiliary material application position 420 and the unloading position 430, and also equal to the spacing between the two product suction mechanisms 342. The two product suction mechanisms 342 work synchronously. One is dedicated to transporting the product to be applied with auxiliary materials from the loading position 410 of the first pull line 310 to the auxiliary material application position 420 of the bottom mold 320, and the other is dedicated to transporting the product with applied auxiliary materials from the auxiliary material application position 420 of the bottom mold 320 to the unloading position 430 of the second pull line 330, resulting in higher work efficiency.

[0080] Furthermore, there are two product positioning mechanisms 350, which are symmetrically arranged on the first pull line 310 and the second pull line 330, respectively, making them suitable for production lines with different flow directions.

[0081] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto.
