Description

Technical Field

[0001] This utility model belongs to the field of zipper head inspection technology, and specifically relates to an automatic inspection machine for finished zipper heads. Background Technology

[0002] Zippers are commonly used closure devices, and the zipper pull, as an important component of the zipper, directly affects the overall quality of the zipper. However, finished zipper pulls may have mismatched models or sizes between the pull and the tab. Therefore, after the zipper pulls are assembled, their quality needs to be inspected to prevent defective products from entering the assembly process. Currently, the commonly used inspection method is manual visual inspection. Because zipper pulls are small, visual inspection can generally only be done by sampling from batches to determine the overall quality of the product. This inspection method requires a high degree of concentration from the inspectors and inevitably results in some defective products entering the finished product.

[0003] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Summary of the Invention

The zipper head pushing mechanism includes a base fixed on the frame, a movable support seat mounted on the base, and a transverse drive mechanism for driving the support seat to move. A material groove for accommodating zipper heads extends from the end of the support seat away from the transverse drive mechanism. The outlet of the zipper head conveying track corresponds to the material groove. The zipper head conveying track and the ejection mechanism are both located on the same side of the material groove. When the material groove is at the outlet of the zipper head conveying track, it is in a receiving position; when the material groove is at the output end of the ejection mechanism, it is in an inspection position. The transverse drive mechanism pushes the material groove from the receiving position to the inspection position. The frame is equipped with a plurality of visual inspection mechanisms for inspecting zipper heads at the inspection position.

A baffle for blocking the blocking rod is protruding from the mounting base toward the material trough. The baffle is located on the moving path of the blocking rod. When the material trough is located at the detection station, the blocking plate is located diagonally below the material trough.

[0009] Furthermore, the ejection mechanism includes an ejection cylinder and a push plate fixed at the output end of the ejection cylinder, as well as a stabilizing seat disposed between the ejection cylinder and the material trough, wherein the stabilizing seat has an elongated groove through which the push plate passes.

[0010] Furthermore, the push plate is also provided with a top plate at one end near the material trough for abutting the zipper head inside the material trough.

[0011] Furthermore, the frame is provided with two sets of zipper head conveying tracks and two sets of zipper head pushing mechanisms. The two sets of zipper head conveying tracks are symmetrically arranged on both sides of the ejection mechanism, and the two sets of zipper head pushing mechanisms are symmetrically arranged on both sides of the ejection mechanism and facing each other. The ejection mechanism is provided with two push plates, and the blocking mechanism is provided with two blocking plates.

[0012] Furthermore, a receiving seat is provided on the frame corresponding to the detection station, and a receiving channel is provided inside the receiving seat.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4As shown, an automatic zipper head inspection machine includes a frame 100, a zipper head conveying track 10 mounted on the frame 100, a zipper head pushing mechanism 1 located at the outlet of the zipper head conveying track 10, and an ejection mechanism 2 mounted on the frame 100. The zipper head pushing mechanism 1 includes a base 11 fixed on the frame 100, a movable support seat 12 mounted on the base 11, and a transverse drive mechanism 13 for driving the support seat 12 to move. A material trough 14 for accommodating zipper heads 20 extends from the end of the support seat 12 away from the transverse drive mechanism 13. The outlet of the zipper head conveying track 10 corresponds to the material trough 14. The zipper head conveying track 10 and the ejection mechanism 2 are both located on the same side of the material trough 14. When the material trough 14 is located at the outlet of the zipper head conveying track 10, it is in a receiving position, at which time the zipper head 20 can be conveyed from the zipper head conveying track 10. The material is fed into the trough 14 at the outlet. The transverse drive mechanism 13 is used to push the trough 14 from the receiving station to the output end of the ejection mechanism 2. When the trough 14 is at the output end of the ejection mechanism 2, it is in the detection station. That is, the transverse drive mechanism 13 is used to push the trough 14 from the receiving station to the detection station. The frame 100 is provided with a number of visual inspection mechanisms for detecting the zipper heads 20 at the detection station. The ejection mechanism 2 is used to eject the zipper heads 20 in the trough 14 at the detection station. The transverse drive mechanism 13 can be a conventional drive mechanism in the art, such as a cylinder or a motor. In this embodiment, a cylinder is preferred. The base 11 is provided with a slide rail 15 and a slide seat 16. The bearing seat 12 is fixed on the slide seat 16. The output end of the transverse drive mechanism 13 is fixed on the slide seat 16. The transverse drive mechanism 13 pushes the slide seat 16, so that the bearing seat 12 moves on the slide rail 15 through the slide seat 16.

[0022] Preferably, in this utility model, the zipper head conveying track 10, the zipper head pushing mechanism 1, and the material trough 14 are all arranged obliquely. It should be noted that, as Figure 4As shown, the automatic zipper head detection machine of this utility model is applicable to existing conventional zipper heads 20 with a zipper head 201 and a zipper tab 202. The existing zipper head 201 has slots 203 on both sides for engaging with the zipper. The zipper head conveying track 10 can use any existing conventional mechanism for conveying the zipper head 20. Accordingly, in this utility model, both sides of the material trough 14 are provided with clamping plates 141 for supporting the zipper head 20. The clamping plates 141 face the direction of the zipper head conveying track 10. When the zipper head conveying track 10 conveys the zipper head 20 into the material trough 14, the slots 203 on both sides of the zipper head 201 can slide through the clamping plates 141. Since the material trough 14 is set at an angle, in order to prevent the zipper head from slipping out of the card plate 141, the zipper head pushing mechanism 1 also includes a stop bar 17 set on the support seat 12 for blocking the zipper head 20 in the material trough 14. Specifically, one end of the stop bar 17 is a stop end 171 that extends from the support seat 12 and is located at the bottom of the material trough 14 (the support seat 12 has a long groove for the stop bar 17 to extend into at the position corresponding to the stop bar 17). The end of the stop bar 17 away from the material trough 14 extends out of the support seat 12 and is connected to the support seat 12 by a spring 18. When the material trough 14 is in the support position, the stop end 171 is located at an angle below the material trough 14, blocking the zipper head 20 that falls into the material trough 14.

[0023] Preferably, the frame 100 is also provided with a blocking mechanism 3. The blocking mechanism 3 is located on the side of the material trough 14 away from the zipper head pushing mechanism 1. The blocking mechanism 3 includes a blocking cylinder 31, a blocking plate 32 fixed to the output end of the blocking cylinder 31, and a mounting seat 33 for mounting the blocking cylinder 31. A baffle 34 for blocking the blocking rod 17 on the bearing seat 12 is protruding from the mounting seat 33 towards the material trough 14. The baffle 34 is located on the moving path of the blocking rod 17. When the transverse drive mechanism 13 pushes the material trough 14 from the receiving station to the inspection station, the blocking end 171 is blocked by the baffle 34 protruding from the mounting seat 33. The transverse drive mechanism 13 continues to drive the material trough 14 to move to the inspection station. At this time, the blocking cylinder 31 needs to act in advance or synchronously so that the blocking plate 32 is located diagonally below the material trough 14 and continues to block the zipper head 20 in the material trough 14.

[0024] Preferably, the ejection mechanism 2 includes an ejection cylinder 21, a push plate 22 fixed to the output end of the ejection cylinder 21, and a stabilizing seat 23 disposed between the ejection cylinder 21 and the material trough 14. The stabilizing seat 23 is fixed on the frame 100. A long groove for the push plate 22 to pass through is opened in the stabilizing seat 23. The long groove in the stabilizing seat 23 makes the push plate 22 more stable and accurate when moving in the long groove, and less prone to deviation. Preferably, the end of the push plate 22 near the material trough 14 is also provided with a stop plate 24 for abutting the zipper head 20 in the material trough 14. After the material trough 14 moves to the inspection station, the stop plate 32 blocks the bottom of the zipper head 20. The ejection cylinder 21 drives the push plate 22 to move towards the material trough 14, so that the stop plate 24 blocks the top of the zipper head 20, making the zipper head 20 less prone to shaking and facilitating subsequent inspection. It should be noted that, since the zipper head conveyor track 10 is arranged at an angle, when the zipper head 20 is located on the zipper head conveyor track 10, the zipper head 20 is in an inclined state, and the bottom of the zipper head 201 faces upward at an angle. The pull tab 202 is located at the bottom of the zipper head 201 in a naturally hanging vertical position. When the zipper head 20 is conveyed into the material trough 14, the state of the zipper head 20 remains unchanged, that is, the bottom of the zipper head 201 faces upward at an angle, and the pull tab 202 is located at the bottom of the zipper head 201 in a naturally hanging vertical position. Preferably, in this utility model, the frame 100 is provided with a first visual inspection mechanism 41 for detecting the bottom of the zipper head 201, a second visual inspection mechanism 42 for detecting one side of the pull tab 202, and a third visual inspection mechanism 43 for detecting the other side of the pull tab 202. 3. Correspondingly, the first visual inspection mechanism 41 is located above the frame 100, and the second visual inspection mechanism 42 and the third visual inspection mechanism 43 are respectively set on the frame 100 and located on both sides of the material trough 14. It should be noted that the first visual inspection mechanism 41, the second visual inspection mechanism 42 and the third visual inspection mechanism 43 of this utility model are all conventional products that can be purchased on the market. Before use, the standard style of the required zipper head 201 or zipper tab 202 is entered into each visual inspection mechanism. When the zipper head 20 in the material trough 14 is located at the inspection station, the corresponding part is visually inspected. In this embodiment, three visual inspection mechanisms are preferably used to inspect the zipper head 201 and zipper tab 202. The number of visual inspection mechanisms can also be adjusted according to actual needs.

[0025] Preferably, the frame 100 of this utility model is provided with two sets of zipper head conveying tracks 10 and two sets of zipper head pushing mechanisms 1. The two sets of zipper head conveying tracks 10 are symmetrically arranged on both sides of the ejection mechanism 2. The two sets of zipper head pushing mechanisms 1 are symmetrically arranged on both sides of the ejection mechanism 2 and facing each other. Correspondingly, the ejection mechanism 2 is provided with two push plates 22. The two push plates 22 are arranged in parallel and are located on both sides of the output end of the ejection cylinder 21, and are respectively located at the positions of the material grooves 14 of the two sets of zipper head pushing mechanisms 1. The ejection cylinder 21 drives the two push plates 22 to move together. The stabilizing seat 23 is provided with two long grooves for the push plates 22 to pass through. Correspondingly, the blocking mechanism 3 is provided with two blocking plates 32 and two stops 34. The two stops 34 are respectively arranged on the moving path of the blocking rods 17 in the two sets of zipper head pushing mechanisms 1.

[0026] Preferred, such as Figure 2 and Figure 3 As shown, a receiving seat 5 is provided on the frame 100 at the position corresponding to the detection station. A receiving channel 51 is provided inside the receiving seat 5. The entrance of the receiving channel 51 corresponds to the output end of the pushing mechanism 2. The zipper head conveyor track 10, the pushing mechanism 2, and the blocking mechanism 3 are all located above the receiving seat 5. Correspondingly, the receiving seat 5 has two receiving channels 51 for material entry at the positions corresponding to the two push plates 22. A first channel 511 and a second channel 512 are spaced apart inside the receiving channels 51. Both the first channel 511 and the second channel 512 are vertically arranged. A partition 52 is rotatably provided between the first channel 511 and the second channel 512 to block the entrance of the first channel 511 or the entrance of the second channel 512. The partition 52 is located at the receiving channel... Inside channel 51, a partition drive mechanism 53 for driving the partition 52 to rotate is provided on one side of the receiving seat 5. The first channel 511 corresponds to the qualified product channel, and the second channel 512 corresponds to the unqualified product channel. When the zipper head 20 is qualified, the partition drive mechanism 53 is activated to block the entrance of the second channel 512. The push cylinder 21 is activated to push the push plate 22 to push the zipper head 20 in the material trough 14 into the first channel 511. If the zipper head 20 is unqualified, the partition 52 rotates to block the entrance of the first channel 511. The push cylinder 21 is activated to push the push plate 22 to push the zipper head 20 into the second channel 512. The partition drive mechanism 53 adopts a conventional cylinder or motor in the art, as long as it can drive the partition 52 to rotate.

[0027] The working principle of this utility model's automatic zipper head inspection machine: Initially, the zipper trough 14 is located at the bearing station. The zipper head conveying track 10 conveys the zipper head 20 to be inspected into the zipper trough 14 on the bearing seat 12. The bottom of the zipper head 20 is blocked by the blocking end 171 of the blocking rod 17. Then, the transverse drive mechanism 13 pushes the bearing seat 12 and the zipper trough 14, causing the zipper trough 14 to move towards the inspection station. During the pushing process of the transverse drive mechanism 13, the blocking end 171 is blocked by the baffle 34. The blocking cylinder 31 controls the action of the blocking plate 32, so that the blocking plate 32 is located diagonally below the zipper trough 14 and continues to block the zipper head 20 in the zipper trough 14. After the zipper trough 14 is located at the inspection station, the push cylinder 21 drives the push plate 22 to move towards the zipper trough 14, so that the top plate 24 blocks the top of the zipper head 20, making the zipper head 20 less prone to shaking. Then, the first visual inspection is performed. The inspection mechanism 41, the second vision inspection mechanism 42, and the third vision inspection mechanism 43 begin inspection. If the inspection is qualified, the partition drive mechanism 53 is activated to block the entrance of the second channel 512. The push cylinder 21 is activated, causing the push plate 22 to push the zipper head 20 in the material trough 14 into the first channel 511. If the zipper head 20 fails the inspection, the partition 52 rotates to block the entrance of the first channel 511. The push cylinder 21 is activated, causing the push plate 22 to push the zipper head 20 into the second channel 512. Then, the transverse drive mechanism 13 drives the carrier 12 and the material trough 14 to return to their original positions. The material trough 14 returns to the receiving position to receive the next zipper head 20 conveyed from the zipper head conveying track 10. The stop bar 17 returns to its original position under the action of the spring 18. After the next zipper head 20 falls into the material trough 14, the above operation is repeated.

[0028] This utility model discloses an automatic zipper head inspection machine. It comprises a zipper head conveying track 10 on a frame 100, a zipper head pushing mechanism 1 at the outlet of the zipper head conveying track 10, and an ejection mechanism 2 on the frame 100. The zipper head pushing mechanism 1 includes a base 11 fixed on the frame 100, a movable support seat 12 on the base 11, and a transverse drive mechanism 13 for driving the support seat 12. The support seat 12 has a material trough 14 for accommodating zipper heads 20. The frame 100 is equipped with several visual inspection mechanisms for inspecting zipper heads 20. This machine can automatically inspect and eject finished zipper heads 20. Compared to existing manual inspection, it has a high degree of automation, higher work efficiency, and higher accuracy, which is beneficial for large-scale production.
