Description

Technical Field

[0001] This utility model relates to the field of labeling technology, specifically to an automatic labeling mechanism. Background Technology

[0002] Labels are printed materials used to identify product models, places of origin, production dates, and other relevant information. They usually have adhesive on the back, making them easy to stick to the product surface.

[0003] There are two common labeling methods. One is to use spring-loaded positioning for the label. After the product is positioned, it is manually pressed. This method can easily cause the positioning pin of the spring-loaded label to stick with the glue on the label. Once the glue hardens and sticks to the positioning pin, the positioning pin will be difficult to pop out, requiring frequent maintenance and cleaning. This results in high maintenance costs, high labor costs, and low production efficiency. The other method is to create an L-shaped backing after the product is positioned and then use the L-shaped backing to apply the label. This method can easily cause the label to shift during the application process, resulting in inconsistent dimensions of the final product and affecting the product's appearance quality. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is an automatic labeling mechanism, comprising:

[0006] A tooling plate, wherein a product groove for placing products is provided on the front surface of the tooling plate;

[0007] A label slot is located on the bottom wall of the product slot, and an adsorption hole is provided in the label slot that penetrates the tooling plate in the front-to-back direction;

[0008] An adsorption groove is formed on the rear surface of the tooling plate, and its position corresponds to the label groove. The adsorption groove is in communication with the adsorption hole.

[0009] A cover plate covers the adsorption tank and is connected to the rear surface of the tooling plate, forming an adsorption cavity with the inner wall of the adsorption tank.

[0010] An electromagnetic valve is connected to the cover plate via an air pipe, which is also connected to the adsorption chamber. The air pipe includes a first air pipe and a second air pipe that are independent of each other.

[0011] A vacuum generator is connected in series with the first air pipe, dividing the first air pipe into a front section air pipe located between the vacuum generator and the solenoid valve and a rear section air pipe located between the vacuum generator and the cover plate.

[0012] When the valve core of the solenoid valve is in the first working position, the front air pipe is connected and the second air pipe is disconnected. High-pressure gas enters the vacuum generator along the front air pipe, causing the vacuum generator to generate a vacuum, and draws air from the adsorption chamber along the rear air pipe, causing the label to be adsorbed in the label slot. When the valve core of the solenoid valve is in the second working position, the second air pipe is connected and the front air pipe is disconnected. High-pressure gas enters the adsorption chamber along the second air pipe and is blown out through the adsorption hole, causing the label to be pasted on the product surface.

[0013] Preferably, the product groove has a through hole, and an insert is embedded in the through hole. The label groove and the adsorption groove are respectively opened on the front and rear surfaces of the insert.

[0014] More preferably, the front surface of the insert protrudes from the bottom wall of the product slot but does not extend beyond the front surface of the tooling plate.

[0015] More preferably, the rear surface of the insert is further provided with a sealing ring groove surrounding the adsorption groove, and a cover plate positioning pin is provided around the sealing ring groove.

[0016] Preferably, a photoelectric sensor is also embedded in the bottom wall of the product slot. The photoelectric sensor is located near the label slot and is electrically connected to the solenoid valve. When a product is placed in the product slot, the photoelectric sensor is triggered, causing the valve core to change to the second working position.

[0017] Preferably, the solenoid valve is connected to the rear surface of the tooling plate, and the solenoid valve is also connected to a lever for changing the valve core to a first working position, the end of the lever extending beyond the edge of the tooling plate and protruding outward.

[0018] More preferably, the tooling plate has a rectangular projection in the front-to-back direction, and the rear surface of the tooling plate is provided with support feet located at the four corners of the tooling plate. The height of the support feet is greater than the thickness of the lever in the front-to-back direction.

[0019] Preferably, the solenoid valve is a three-position five-way center-sealed solenoid valve, and the vacuum generator is connected to the rear surface of the tooling plate.

[0020] Preferably, there are multiple adsorption holes, which are evenly distributed on the bottom wall of the label groove.

[0021] Preferably, the front surface of the tooling plate is further provided with product positioning posts, and there are multiple product positioning posts arranged around the product groove.

[0022] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0023] The automatic labeling mechanism provided by this utility model includes a tooling plate with a product groove on its front surface, a label groove located on the bottom wall of the product groove, an adsorption groove on the rear surface of the tooling plate corresponding to the label groove, a cover plate covering the adsorption groove and the inner wall of the adsorption groove to form an adsorption cavity, a solenoid valve connected to the adsorption cavity through an air pipe, and a vacuum generator. An adsorption hole penetrating the tooling plate and the adsorption groove is opened in the label groove. The air pipe includes independent first and second air pipes. The vacuum generator is connected in series with the first air pipe, dividing it into a front section and a rear section. When the solenoid valve core is in the first working position, the front section air pipe is connected, and high-pressure gas enters the vacuum generator along the front section air pipe, creating a vacuum and drawing air from the adsorption cavity along the rear section air pipe, causing the label to be adsorbed in the label groove. When the valve core is in the second working position, the second air pipe is connected, and high-pressure gas enters the adsorption cavity along the second air pipe and is blown out through the adsorption hole, causing the label to be pasted on the product surface. This achieves vacuum adsorption and automatic air-blowing pasting of the label, resulting in low maintenance costs, high production efficiency, and good label positioning accuracy.

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art.

[0034] like Figures 1 to 6As shown, the automatic labeling mechanism provided by this utility model includes: a tooling plate 10, a label slot 20, an adsorption slot 30, a cover plate 40, a solenoid valve 50, and a vacuum generator 60. The tooling plate 10 is vertically arranged; this vertical arrangement and the corresponding front-back and up-down directions are for illustrative purposes only and do not represent a limitation on actual use. In actual use, the tooling plate 10 can be horizontally or inclined. The front surface of the tooling plate 10 has a product slot 11 for placing products. When a product is placed in the product slot 11, the surface of the product to be labeled can be made to fit against the bottom wall of the product slot 11. The front surface of the tooling plate 10 also has multiple product positioning posts 12 surrounding the product. The groove 11 is provided to ensure that the product can be placed in place; the label groove 20 is opened on the front surface of the tooling plate 10, and the label groove 20 is located on the bottom wall of the product groove 10. Multiple adsorption holes 21 are opened in the label groove 20, penetrating the tooling plate 10 in the front-to-back direction, and are evenly distributed on the bottom wall of the label groove 20; the adsorption groove 30 is opened on the rear surface of the tooling plate 10, corresponding to the label groove 20, and communicates with the adsorption holes 21; the cover plate 40 covers the adsorption groove 30 and is connected to the rear surface of the tooling plate 10, and the cover plate 40 and the inner wall of the adsorption groove 30 form an adsorption cavity 31; the solenoid valve 50 and the vacuum generator 60 are both connected to the rear surface of the tooling plate 10. Specifically, the solenoid valve 50... Valve 50 is connected to cover plate 40 via an air pipe, which is also connected to adsorption chamber 31. The air pipe includes a first air pipe and a second air pipe 72, which are independent of each other. Vacuum generator 60 is connected in series with the first air pipe, dividing the first air pipe into a front section air pipe 711 located between vacuum generator 60 and solenoid valve 50 and a rear section air pipe 712 located between vacuum generator 60 and cover plate 40. Solenoid valve 50 is a three-position five-way center-sealed solenoid valve. The valve core of solenoid valve 50 (not shown in the figure) has a first working position and a second working position. When the valve core of solenoid valve 50 is in the first working position, the front section air pipe 711 is connected and the second air pipe 72 is disconnected. High-pressure gas enters vacuum generator 60 along the front section air pipe 711. 0. The vacuum generator 60 generates a vacuum and draws air from the adsorption chamber 31 along the rear air pipe 712, causing the label to be adsorbed into the label slot 20. When the valve core of the solenoid valve 50 is in the second working position, the second air pipe 72 is connected and the front air pipe 711 is disconnected. The vacuum generator 60 does not work, and high-pressure gas enters the adsorption chamber 31 along the second air pipe 72 and is blown out through the adsorption hole 21, so that the label is pasted on the surface of the product to be labeled. This realizes the vacuum adsorption and automatic air blowing of the label. During the adsorption process, the edge of the label does not touch, there is no need to set spring pressure positioning pins, there is no cleaning operation of spring pressure positioning pins, the maintenance cost is low, the production efficiency is high, the label position is accurate, and it does not affect the appearance quality of the product.

[0035] For ease of processing, in this embodiment, a through hole 13 is provided in the product groove 11, and an insert 80 is embedded in the through hole 13. The label groove 20 and the adsorption groove 30 are respectively provided on the front and rear surfaces of the insert 80. The front surface of the insert 80 protrudes from the bottom wall of the product groove 11 and does not exceed the front surface of the tooling plate 10. The rear surface of the insert 80 is also provided with a sealing ring groove 81 surrounding the adsorption groove 30. A sealing ring (not shown in the figure) is embedded in the sealing ring groove 81. When the cover plate 40 is locked, the adsorption cavity 31 is sealed around. The sealing ring groove 81 is provided with cover plate positioning pins 82 around it.

[0036] For ease of operation, in this embodiment, the solenoid valve 50 is also connected to a lever 51 for changing the valve core to the first working position. The end of the lever 51 extends beyond the edge of the tooling plate 10 and outwards. Furthermore, the projection of the tooling plate 10 in the front-back direction is rectangular. The rear surface of the tooling plate 10 is provided with support feet 14, which are located at the four corners of the tooling plate 10. The height of the support feet 14 is greater than the thickness of the lever 51 in the front-back direction. At the same time, the bottom wall of the product slot 11 is also provided with a photoelectric sensor mounting hole 15. A photoelectric sensor is embedded in the photoelectric sensor mounting hole 15. The photoelectric sensor is located near the label slot 20 and is electrically connected to the solenoid valve 50. When a product is placed in the product slot 11, the photoelectric sensor is triggered, causing the valve core to change to the second working position.

[0037] The actual steps for use are as follows:

[0038] 1. The operator first places the label into the label slot, then moves the lever to change the valve core of the solenoid valve to the first working position. At this time, the air passage of the mechanism is as follows: Figure 7 As shown, the solenoid valve sends high-pressure gas into the vacuum generator along the front gas pipe, connecting the front gas pipe and disconnecting the second gas pipe. The vacuum generator generates a vacuum and extracts air from the adsorption chamber along the rear gas pipe, putting the adsorption chamber in a low-pressure or vacuum environment, thereby adsorbing the label onto the bottom wall of the label slot through the adsorption hole.

[0039] 2. The operator adjusts the product to align with the product positioning post, then places the product into the product slot. Once in place, the product blocks the photoelectric sensor, triggering it. The photoelectric sensor sends an electrical signal to actuate the solenoid valve, causing the valve core to change to the second working position. At this time, the air path of the mechanism is as follows: Figure 8 As shown, the solenoid valve sends high-pressure gas into the adsorption chamber along the second air pipe. The second air pipe is connected, the first air pipe is disconnected, the vacuum generator does not work, and the second air pipe is also disconnected. The high-pressure gas in the adsorption chamber is blown out in the opposite direction through the adsorption hole, so that the label is pasted on the surface of the product to be labeled.

[0040] Thanks to the linkage between the photoelectric sensor and the solenoid valve, the mechanism can achieve intelligent switching of the labeling process through a closed-loop control mechanism, which shortens the assembly cycle by 20% and achieves a positioning accuracy of ±0.1mm.

[0041] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
