Description

Technical Field

[0001] This invention relates to a perforated sign output positioning device, belonging to the technical field of sign positioning. Background Technology

[0002] Currently, existing wire coils still rely on manual tagging. This involves operators taking the tag and hook, threading the hook through the hole in the tag to clamp it, and then suspending the hook onto different packing steel wires or straps approximately 300mm from both ends of the inner coil. The main reason this tagging process cannot be fully automated is the high precision required for the hook and tag perforation operation. Furthermore, the varying shapes of the tags after laser marking make it difficult to determine the precise perforation location. Summary of the Invention

[0003] Purpose of the invention: To address the above-mentioned problems, the purpose of this invention is to provide a self-positioning system for perforated signs, which enables precise positioning of perforated signs, thereby providing support for the realization of a fully automated wire coil labeling system.

[0004] Technical Solution: A perforated sign output positioning device includes a laser marking machine and a sign positioning mechanism. The laser marking machine is used to print signs, and the signs have perforations. The sign positioning mechanism includes a mounting base, a sliding plate, a limiting side plate, a side plate cylinder, a limiting bottom plate, and a bottom plate cylinder. The sliding plate is inclinedly positioned at the exit of the laser marking machine via the mounting base. A side notch is provided on one side of the lower end of the sliding plate, and the side plate cylinder and bottom plate cylinder are located on the back. The output end of the side plate cylinder is connected to the limiting side plate, and the output end of the bottom plate cylinder is connected to the limiting bottom plate. The limiting side plate is located on both sides of the lower end of the sliding plate and opens or clamps under the drive of the side plate cylinder. The limiting bottom plate is located at the bottom end of the sliding plate and rises or falls under the drive of the bottom plate cylinder. After the sign slides along the sliding plate to the bottom, it is clamped and limited on both sides by the limiting side plate, and blocked and limited at the bottom by the limiting bottom plate. The perforation overlaps with the side notch.

[0005] The principle of this invention is as follows: After the label is printed, it falls from the exit of the laser marking machine onto the slide plate and slides down to the bottom. Then, it is clamped and limited on both sides by limiting side plates, and blocked and limited at the bottom by a limiting base plate, thus forming a multi-point limiting structure to ensure the positioning accuracy of the label. At this time, the perforation of the label overlaps with the side notch, allowing the subsequent hook to pass directly through the perforation and side notch in sequence while the label is clamped, completing the clamping operation between the hook and the label and ensuring positioning accuracy.

[0006] Furthermore, the system also includes an image acquisition module and an acquisition drive mechanism. The acquisition drive mechanism includes a bracket, a slider, a slide rail, and an electric cylinder. The slide rail is fixed to the laser marking machine, and the slider is mounted on the slide rail. One end of the bracket is connected to the slider, and the other end is connected to the image acquisition module. The image acquisition module faces the front of the slide plate. Driven by the electric cylinder, the image acquisition module moves to the slide plate to capture an image to identify whether the perforation and the side notch overlap, or moves away from the slide plate to expose the sign. In this structure, the image acquisition module is used for verification, which further improves the accuracy of the system and enhances the degree of automation. At the same time, the image acquisition module can be moved away from the slide plate when not in operation without affecting the subsequent hook clamping operation.

[0007] Furthermore, the sign positioning mechanism also includes a wear-resistant stop strip, which is Ω-shaped and extends along the outer edge of the side notch. The notch of the wear-resistant stop strip is aligned with the perforation of the sign. In this structure, the wear-resistant stop strip, a vulnerable component, clamps the hook after it passes through the perforation, improving positioning accuracy and facilitating maintenance.

[0008] Furthermore, the sign positioning mechanism also includes a photoelectric sensor. The bottom end of the slide plate is provided with a bottom notch, and the photoelectric sensor is fixed in the bottom notch to detect whether the sign has slid into place along the slide plate.

[0009] Furthermore, the sign positioning mechanism also includes a pressure plate base, a limiting pressure plate, and a pressure plate clamping cylinder. The pressure plate base is located on the side of the mounting base, and the pressure plate clamping cylinder is fixed on the pressure plate base. The limiting pressure plate is fork-shaped, with one end fixed to the pressure plate clamping cylinder and the other end having a side opening. The limiting pressure plate is aligned with the lower end of the sliding plate, and the side opening of the limiting pressure plate is aligned with the side notch of the sliding plate. In this structure, after the sign slides to the bottom along the sliding plate, the pressure plate clamping cylinder drives the limiting pressure plate to press onto the sign. The hook passes through the side opening of the limiting pressure plate, the sign through the hole, and the side notch of the sliding plate in sequence, completing the assembly of the hook and the sign, thereby completing the sign removal operation.

[0010] Furthermore, the sign positioning mechanism also includes a pressure plate transverse movement cylinder, which is fixed on the pressure plate base and the pressure plate clamping cylinder is fixed on the pressure plate transverse movement cylinder to drive the limiting pressure plate to move laterally and leave the slide plate from the end fixed to the pressure plate clamping cylinder, which facilitates maintenance.

[0011] Furthermore, the side opening of the limiting pressure plate gradually narrows from the inside to the outside. In this structure, after the hook passes through the side opening, the label perforation, and the side notch of the sliding plate in sequence to complete the assembly of the hook and the label, the limiting pressure plate moves away in the opposite direction under the drive of the pressure plate transverse movement cylinder to achieve precise self-positioning, which facilitates the assembly of the hook and the label.

[0012] Furthermore, the limiting side plate includes a left baffle and a right baffle, which are located on the left and right sides of the lower end of the skateboard, respectively. The right baffle is a split structure, including an upper baffle and a lower baffle, with the side notch sandwiched between the upper and lower baffles. The left baffle, upper baffle, and lower baffle are respectively connected to the side plate cylinder. In this structure, the split right baffle, sandwiched between the two sides of the side notch of the skateboard, not only limits the lateral positioning of the sign but also prevents the hook from being blocked and interfered with after passing through the side notch of the skateboard, thus improving safety.

[0013] Furthermore, the left baffle is located between the pressure plate clamping cylinder and the sliding plate, and is U-shaped with an opening at the top. The end of the limiting pressure plate fixed to the pressure plate clamping cylinder has a narrow opening, which engages with the upper opening of the left baffle. In this structure, through a compact design within a very small space, the left baffle and the limiting pressure plate do not interfere with each other, ensuring stability in use.

[0014] Furthermore, the sign positioning mechanism also includes a limiting cover, which covers the upper part of the slide plate to prevent the sign from shifting during the sliding process and to prevent splashes from hitting the slide plate.

[0015] Beneficial effects: Compared with the prior art, the advantages of the present invention are: through the high-precision sign positioning and detection structure, a foundation is provided for the automatic clamping of signs and hooks, thus making fully automated wire coiling and sign hanging operations possible.

[0021] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0022] A perforated sign output positioning device, as shown in the attached document. Figure 1As shown, it includes a laser marking machine 1, a sign positioning mechanism 2, an image acquisition module 3, an acquisition drive mechanism 4, and a sign 5.

[0023] Laser marking machine 1 is used to print sign 5, as shown in the attached image. Figure 4 As shown, a perforation 51 is provided on sign 5, as per the attached diagram. Figures 2-5 As shown, the sign positioning mechanism 2 includes a mounting base 2a, a sliding plate 2b, a limiting side plate 2c, a side plate cylinder 2d, a limiting base plate 2e, a base plate cylinder 2f, a wear-resistant baffle 2g, a photoelectric sensor 2h, a pressure plate base 2i, a limiting pressure plate 2j, a pressure plate clamping cylinder 2k, a pressure plate transverse movement cylinder 2m, and a limiting guard 2n.

[0024] The slide plate 2b is tilted and positioned at the exit of the laser marking machine 1 via the mounting base 2a, as shown in the attached figure. Figure 3 As shown, the skateboard 2b has a side notch 2b1 on one side of its lower end, a bottom notch 2b2 at its bottom end, a side plate cylinder 2d and a bottom plate cylinder 2f on its back, and a limiting cover 2n on its upper part.

[0025] The wear-resistant baffle 2g is Ω-shaped and extends along the side notch 2b1. The notch of the wear-resistant baffle 2g is aligned with the perforation 51 of the nameplate 5. The photoelectric sensor 2h is fixed inside the bottom notch 2b2.

[0026] As attached Figure 4 , 5 As shown, the output end of the side plate cylinder 2d is connected to the limiting side plate 2c. The limiting side plate 2c is located on both sides of the lower end of the slide plate 2b and opens or clamps under the drive of the side plate cylinder 2d. In this embodiment, the specific limiting side plate 2c includes a left baffle 2c1 and a right baffle 2c2. The left baffle 2c1 and the right baffle 2c2 are located on the left and right sides of the lower end of the slide plate 2b, respectively. The right baffle 2c2 is a split structure, including an upper baffle 2c3 and a lower baffle 2c4. A side notch 2b1 is sandwiched between the upper baffle 2c3 and the lower baffle 2c4. The left baffle 2c1, the upper baffle 2c3 and the lower baffle 2c4 are respectively connected to the side plate cylinder 2d.

[0027] As attached Figure 2 , 3 As shown, the output end of the base plate cylinder 2f is connected to the limiting base plate 2e, which is located at the bottom end of the slide plate 2b and is raised or lowered under the drive of the base plate cylinder 2f.

[0028] As attached Figure 2 As shown, the pressure plate base 2i is located to the side of the mounting base 2a, the pressure plate transverse movement cylinder 2m is fixed on the pressure plate base 2i, and the pressure plate clamping cylinder 2k is fixed on the pressure plate transverse movement cylinder 2m, as shown in the attached figure. Figure 4 , 5As shown, the limiting pressure plate 2j is fork-shaped, with one end fixed to the pressure plate clamping cylinder 2k and the other end having a side opening 2j1. The limiting pressure plate 2j is aligned with the lower end of the sliding plate 2b, and the side opening 2j1 of the limiting pressure plate 2j is aligned with the side notch 2b1 of the sliding plate 2b. Preferably, the side opening 2j1 of the limiting pressure plate 2j gradually narrows from the inside to the outside.

[0029] In this embodiment, in order to achieve non-interference between the driving of each cylinder in a narrow space, it is preferable to set the left baffle 2c1 between the pressure plate pressing cylinder 2k and the slide plate 2b. The whole is U-shaped with an opening at the top. The end of the limiting pressure plate 2j that is fixed on the pressure plate pressing cylinder 2k has a narrow opening 2j2, which is inserted into the upper opening of the left baffle 2c1.

[0030] In this embodiment, when positioning the sign, after the sign 5 slides along the slide plate 2b to the bottom, it is clamped and limited on both sides by the limiting side plate 2c, blocked and limited at the bottom by the limiting bottom plate 2e, and pressed and limited at the top by the limiting pressure plate 2j. The upper part of the through hole 51 is aligned with the side opening 2j1 of the limiting pressure plate 2j, and the lower part overlaps with the position of the wear-resistant strip 2g notch in the side notch 2b1.

[0031] As attached Figure 1 As shown, the acquisition drive mechanism 4 includes a bracket 4a, a slider 4b, a slide rail 4c, and an electric cylinder 4d. The slide rail 4c is fixedly connected to the laser marking machine 1. The slider 4b is mounted on the slide rail 4c. One end of the bracket 4a is connected to the slider 4b, and the other end is connected to the image acquisition module 3. The image acquisition module 3 faces the front of the slide plate 2b. The image acquisition module 3 moves to the slide plate 2b under the drive of the electric cylinder 4d to capture an image to identify whether the perforation 51 overlaps with the side notch 2b1, or to move away from the slide plate 2b to expose the sign 5.

[0032] The image acquisition module 3 can use a mature industrial camera for image acquisition and recognition. Specifically, in this embodiment, an integrated solution of industrial camera, light source and reflector can be adopted. The industrial camera, light source and reflector are all facing the slide plate 2b. The reflector is fixed to the bracket 4a. The industrial camera and light source are fixed on the reflector, thereby improving the clarity of the shooting and facilitating image recognition.

[0033] The perforated sign output positioning device of this embodiment includes a sign positioning stage and a sign detection stage.

[0034] During the sign positioning stage, after the sign is printed by the laser marking machine, it falls from its exit onto the slide plate and slides down to the bottom. At this time, the photoelectric sensor 2h detects whether the slide has reached the correct position and signals the side plate cylinder 2d to drive the limiting side plate 2c to perform a clamping action, thus fixing the sign to the left and right. At the same time, the signal controls the pressure plate lateral movement cylinder 2m to drive the limiting pressure plate 2j to the top of the slide plate 2b. Then, the signal controls the pressure plate pressing cylinder 2k to drive the limiting pressure plate 2j to be aligned and pressed down. The narrow opening 2j2 is inserted into the upper opening of the left baffle 2c1. The side opening 2j1, the through hole 51, and the side notch 2b1 complete the positioning of the sign.

[0035] During the sign inspection stage, the electric cylinder 4D drives the image acquisition module 3 to reach the position above the slide plate 2b, captures an image of the sign after it is positioned, and identifies whether the side opening 2j1 of the limit pressure plate 2j, the perforation 51 of the sign 5, and the notch of the wear-resistant strip 2g overlap, thereby detecting whether the positioning of the sign is accurate.

[0036] After the inspection is completed, the external robot-driven hook can sequentially pass through the side opening 2j1 of the limit pressure plate 2j, the through hole 51 of the sign 5, and the notch of the wear-resistant stop strip 2g to insert and remove the sign, thereby completing the automated sign hanging operation.
