Description

Technical Field

[0001] The utility model relates to the field of automatic packaging, in particular to the technical field of packaging box label smoothing, and specifically is a label smoothing device suitable for concave and convex surfaces. Background Art

[0002] As the competition in the semiconductor product market becomes increasingly fierce, competitiveness is ensured, and as customer demand continues to increase, the quality of shipped products and labor costs have become the company's primary goals. Every day, we must not only ensure the smooth progress of the production plan and complete the shipping plan, but also ensure that the quality of shipped products in each process meets customer needs.

[0003] In order to ensure a dominant position in the semiconductor market, the requirements for product quality are becoming increasingly higher. After the products leaving the warehouse are packed in outer boxes, product information labels need to be affixed to the side of the outer boxes.

[0004] However, in actual production, it was found that the main reason was that the material of the outer box and the existing smoothing mechanism caused the labels to fall off or bulge inside during transmission, which posed a major quality risk and led to customer complaints. Specifically:

[0005] (1) Due to the material of the outer box, the side of the box cannot always remain vertical; and because the material of the outer box is relatively soft, the surface of the box presents different concave and convex surfaces, which may cause incomplete label sticking;

[0006] (2) The current label smoothing mechanism adopts a single-roller rigid design to smooth the label. The smoothing mechanism has a single stroke and incomplete smoothing, which easily causes the label to fall off due to poor adhesion. Summary of the invention

[0043] The utility model provides a label smoothing device suitable for concave and convex surfaces, which is used in the process of sticking labels on outer packaging boxes. The utility model does not limit the type of outer packaging boxes, but the structure of the label smoothing device suitable for concave and convex surfaces is particularly suitable for the case where the material of the outer packaging box is relatively soft.

[0044] In general, the label smoothing device for concave and convex surfaces proposed in the present invention mainly includes a smoothing unit, a spring assembly, a No. 1 cylinder 3, and a No. 2 cylinder 4. Figure 1 , which shows the arrangement relationship of the smoothing unit, the spring assembly, the No. 1 cylinder 3, and the No. 2 cylinder 4.

[0045] In order to achieve the purpose of enabling the smoothing device to fully contact and smooth the label and ensure that the label is firmly, stably and reliably adhered, the problem found in the background technology in actual production is solved, which is mainly due to the problems of the material of the outer packaging box and the existing smoothing mechanism, resulting in the label falling off or bulging inside during transmission, with major quality risks and customer complaints. Specifically: 1. Due to the material of the outer packaging box, the side of the box cannot always remain in a vertical state; and due to the reasons such as the soft material of the outer packaging box, the surface of the box presents different concave and convex surfaces, and incomplete label adhesion will occur; 2. The current label smoothing mechanism adopts a single-roller rigid design to smooth the label, and the smoothing mechanism has a single stroke, and there is an incomplete smoothing phenomenon, which easily causes the label to be loosely adhered and fall off. For this reason, in the technical solution provided in this embodiment, through the smoothing unit and the spring assembly, when the label is smoothed, the device can automatically adapt to the different concave and convex surfaces of the outer packaging box, so that the device can fully contact and smooth the label, ensuring that the label is firmly, stably and reliably adhered, and the quality is ensured.

[0046] Specifically, Figure 1 As shown, in the device provided in this embodiment, two mutually perpendicular cylinders are configured, the No. 2 cylinder 4 is horizontally arranged, and the cylinder shaft of the No. 2 cylinder 4 is provided with an L-shaped connecting plate 5, the vertical end of the connecting plate 5 is connected to the cylinder shaft, and the horizontal end is located at the top of the No. 2 cylinder 4 and the No. 1 cylinder 3 is installed on the top, and the No. 1 cylinder 3 is vertically arranged. When in use, the cylinder shaft of the No. 2 cylinder 4 is provided with an L-shaped connecting plate 5 and is linked with the No. 1 cylinder 3;

[0047] Next, the No. 1 cylinder 3 installed on the No. 2 cylinder 4 is arranged vertically to the No. 2 cylinder 4, and the moving direction of the cylinder shaft of the No. 1 cylinder 3 is perpendicular to the moving direction of the cylinder shaft of the No. 2 cylinder 4. The cylinder shaft of the No. 1 cylinder 3 is connected with a spring assembly and a smoothing unit through a fixed block 1, and the No. 1 cylinder 3 drives the fixed block 1 to drive the smoothing unit to move in the direction close to or away from the label; further, in combination with the foregoing, the No. 2 cylinder 4 drives the No. 1 cylinder 3 to drive the smoothing unit to move back and forth multiple times in a direction parallel to the label, so as to achieve the multiplicity of the smoothing stroke, and perform two back and forth label smoothing operations to ensure that the smoothing roller can fully contact the surface of the outer box to smooth the label.

[0048] What needs to be specifically explained is the structure of the smoothing unit and the spring assembly, such as Figure 4As shown, the smoothing unit in this embodiment adopts a structure of a smoothing roller 2 and a roller bracket 6, wherein the roller bracket 6 is arranged in a U shape, with the opening facing the label direction, and the corresponding smoothing roller 2 is vertically installed at the opening of the roller bracket 6;

[0049] Taking into account that the smoothing unit can adapt the label to different convex and concave surfaces of the outer packaging box as much as possible during a limited number of smoothing processes, so that it can be fully contacted and smoothed, on the one hand, the smoothing unit is arranged with four groups of equal intervals from top to bottom along the fixed block 1 to achieve the effect of operating multiple labels at the same time; on this basis, the radius of the smoothing roller 2 is larger than the straight-line distance between the end of the roller bracket 6 close to the label and the central axis of the smoothing roller 2, and it is further required that the outer diameter of the smoothing roller 2 is larger than the width of the roller bracket 6, which can ensure that the arc surface of the smoothing roller 2 exposed from the roller bracket 6 can achieve sufficient contact with the label, thereby ensuring that the force on the label is balanced and sufficient.

[0050] As mentioned above, a spring assembly is also provided in the present embodiment so that the smoothing unit can automatically adapt to the uneven surfaces of different outer packaging boxes to achieve full contact and avoid the problem of insufficient contact during smoothing by a rigid mechanism; therefore, the spring assembly with elastic design includes a spring 7 and a guide rod 8, the head of the guide rod 8 is limited on one side of the fixed block 1, the other end of the guide rod 8 passes through the fixed block 1 and is installed on the roller bracket 6 by bolts, and the spring 7 is sleeved on the guide rod 8 and is located between the fixed block 1 and the roller bracket 6. When the smoothing unit does not contact the label, the spring 7 is in an initial state, and the head of the guide rod 8 is against the fixed block 1, and when the smoothing unit contacts the label and is pressed by the uneven surface, the smoothing roller 2 resists the action of the spring 7 and can retreat under the guidance of the guide rod 8, thereby achieving the effect of adaptively adjusting the smoothing position.

[0051] Since the guide rod 8 is installed on the vertical end of the U-shaped roller bracket 6, in order to prevent the smoothing roller 2 from tilting and getting stuck during operation, a group of guide rods 8 arranged up and down are installed on the roller bracket 6 in each smoothing unit.

[0052] Preferably, the elastic force of spring 7 is in the range of 10-15N, which ensures that the label is smoothed against the outer box while ensuring the elastic force, and does not cause greater deformation of the outer box surface due to excessive elastic force, which can effectively avoid other problems such as squeezing caused by excessive or insufficient elastic force.

[0053] like Figure 3As shown, the No. 1 cylinder 3 also has a No. 1 sensor 9 and a No. 2 sensor 10 corresponding to the extension and retraction of the cylinder shaft, and the No. 2 cylinder 4 also has a No. 3 sensor 11 and a No. 4 sensor 12 corresponding to the extension and retraction of the cylinder shaft; the No. 1 sensor 9, the No. 2 sensor 10, the No. 3 sensor 11 and the No. 4 sensor 12 are all electrically connected to the PLC controller; combined with the above structure, when in use, the outer packaging box moves to a position and then stops, the signal is triggered, the No. 1 cylinder 3 extends, and after completion, the No. 1 sensor 9 is triggered, and the spring assembly acts to make the smoothing roller 2 fully contact with the surface of the outer packaging box, and at the same time, the signal of the No. 1 sensor 9 is fed back to the PLC, and the PLC controls the No. 2 cylinder 3 through a delay. Cylinder 4 moves, and cylinder No. 2 drives cylinder No. 1 3 to extend through the connecting plate. After the extension is completed, sensor No. 3 11 is fed back to the PLC to control cylinder No. 2 to retract, so that the smoothing roller 2 can smooth the label pasted on the surface of the outer packaging box twice. After cylinder No. 2 4 retracts, it triggers sensor No. 4 12, and the signal feedback PLC controls cylinder No. 1 3 to retract. After retracting, it triggers sensor No. 2 10, and the signal feedback PLC causes the outer packaging box to flow out. By using the above-mentioned PLC communication technology, the magnetic induction sensor is triggered to feedback the arrival signal after the cylinder moves, and the smoothing mechanism is fully in contact with the surface of the outer packaging box through the optimization of PLC and signal delay time.

[0054] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
