Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a labeling device with high labeling accuracy. Background Art

[0002] The most commonly used labeling equipment is the fully automatic labeling machine. The fully automatic labeling machine is a device that can stick rolled paper labels or metal foil labels on PCBs, products or specified packaging. The labels have adhesive on the back and are regularly arranged on the glossy backing paper. The peeling unit on the labeling machine can automatically peel them off.

[0003] In the actual production process, the label will be transported out of the stripping unit, and then the label on the stripping unit will be adsorbed and transported to the product through the label suction head. In the process of attaching the label to the product, the label needs to be accurately attached to the labeling frame of the product. Nowadays, a two-dimensional plane sensor is usually used to obtain the labeling position of the product to be labeled. The sensor usually causes the image size obtained by the two-dimensional plane sensor to be inconsistent due to the different distances between the label and the two-dimensional plane sensor, which in turn causes a large error in labeling. Ultimately, in the actual production process, the error rate of label attachment in the label frame is high. Utility Model Content

Through the cooperation between the upward positioning camera and the downward detection camera, the efficiency of labeling can be effectively improved, and at the same time, the error during labeling can be effectively reduced.

The top surface of the working platform 1 is provided with a peeling unit 2, a labeling unit 3 and a three-dimensional moving module 4 along the Y-axis direction. The peeling unit 2 is a withdrawable peeling machine, which belongs to the existing equipment and is used for the storage, transportation and peeling of labels. The peeling unit 2 can transport the labels inside it to the end close to the staff, which is the labeling end. The labeling unit 3 is used for the transportation of products. The staff will place the products in the labeling unit 3, and then in the subsequent process, the products will be labeled.

[0037] like Figure 2 As shown, the labeling unit 3 includes a mold placement table 32 arranged on the working platform 1. The model of the mold placement table 32 can be changed according to the needs of the actual product to adapt to products of different sizes and shapes. The top surface of the mold placement table 32 is provided with a placement groove 321 for accommodating the product. The placement groove 321 is a rectangular groove. The staff directly places the product in the placement groove 321, thereby achieving the function of fixing the product. The mold placement table 32 is set on the working platform 1 through the product transportation linear module 31. In this specific embodiment, the linear module includes the following structure: two groups of symmetrically arranged guide rails; a slider is arranged on the top surface of each group of guide rails; and a cylinder or motor for driving the slider to move is arranged between the two groups of guide rails.

A cavity is provided on one side of the nozzle head 421 close to the nozzle rubber package 422 , through which the vacuum adsorption device can be connected to the through hole 4221 .

[0041] like Figure 3 As shown, a positioning unit 7 is synchronously arranged on one side of the rotating motor 41, and the positioning unit 7 includes an upward positioning camera 71 with a lens facing downward and identifying the labeling mark point on the labeling unit 3, and the labeling unit 3 is provided with a mark point for the upward positioning camera 71 to align. The upward positioning camera 71 includes a camera 711 installed on the side wall of the fixing member 46. An annular light source 712 installed on the side wall of the fixing member 46 is arranged below the camera 711.

[0042] like Figure 1 and Figure 5As shown, the top surface of the working platform 1 is provided with a pressing mechanism 5 for pressing the label onto the product in the mold placement table 32, wherein the pressing mechanism 5 includes: a guide rod 51 arranged on the top surface of the working platform 1 and arranged along the Z-axis direction, and an upper fixed plate 52 arranged on the top surface of the guide rod 51. The number of guide rods 51 is four and they are arranged in an array. An electric box 521 is arranged on the top surface of the upper fixed plate 52. The electric box 521 has the functions of arranging circuits or displaying various data. The top surface of the upper fixed plate 52 is provided with a cylinder 522 arranged along the Z-axis direction, and the cylinder 522 is located inside the electric box 521. The driving end of the cylinder 522 passes through the upper fixed plate 52 and is connected to a middle plate 53, and the middle plate 53 slides axially along the guide rod 51 through the shaft sleeve 511. The cylinder 522 can drive the middle plate 53 to slide up and down. The bottom surface of the middle plate 53 is provided with a pressing plate 54 that can contact the mold placement table 32. A plurality of heating couples 541 are arranged on both sides of the pressing plate 54. When the product is transported to the bottom of the pressing plate 54 through the labeling unit 3, the cylinder 522 drives the middle plate 53 to move downward, and the middle plate 53 drives the pressing plate 54 to move downward, and the pressing plate 54 finally presses and heats the label on the product to achieve label pressing.

[0043] Working principle: The staff first places the product in the placement slot 321. The label suction head 42 absorbs the label in the stripping unit 2 and transports the label to the labeling unit 3 through the three-dimensional moving module 4. During the transportation process, the label suction head 42 will pass through the downward detection camera, which will detect the state between the label and the label suction head 42, such as whether the label is tilted. At the same time, the upward positioning camera 71 moves simultaneously with the movement of the label suction head 42. Finally, the label suction head 42 will transport the label to the label frame of the product. Because the distance between the camera 711 of the upward positioning camera 71 and the label suction head 42 is certain, the upward positioning camera 71 detects the error between it and the mark point, and can detect the error between the label and the label frame. In this way, the accuracy of labeling can be detected. After the label is affixed to the product, the product moves to the bottom of the pressing plate 54 driven by the product transportation linear module 31, and the pressing plate 54 moves downward to press and heat the label so that the label is fixed on the product.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
