Description

Technical Field

[0001] This utility model mainly relates to the field of labeling device technology, specifically to a precision casting labeling device. Background Technology

[0002] In modern manufacturing, precision castings are key components widely used in aerospace, automotive manufacturing, medical devices, and other fields. Accurate labeling of precision castings is a crucial step in the production process to facilitate product traceability, information identification, and quality control.

[0003] Currently, the most common methods for labeling castings on the market include manual labeling and automated labeling equipment. Manual labeling relies on operators to manually pick up, place, and attach labels, which is not only inefficient and difficult to meet the needs of large-scale production, but also prone to label placement accuracy being affected by human factors, resulting in quality problems such as label skew, air bubbles, and curling edges. This leads to non-standard product labeling and affects subsequent quality inspection and traceability.

[0004] While automated labeling equipment has improved labeling efficiency to some extent, it still has many shortcomings. The label conveying mechanism of some equipment has poor stability, easily leading to paper jams and label breakage during label separation, affecting production continuity. The positioning accuracy of the labeling mechanism is insufficient, making it difficult to meet the precise labeling requirements of castings of different specifications. Furthermore, most existing labeling equipment lacks an effective label compaction process, resulting in labels not adhering tightly to the casting surface after application. This leads to labels easily falling off or curling during subsequent transportation and use, causing loss of product information and reducing product reliability and market competitiveness.

[0005] As the precision casting production becomes increasingly sophisticated and automated, there is an urgent need for a specialized labeling device that can achieve efficient and accurate labeling while ensuring a firm and secure label adhesion. This device would address the problems of low efficiency, poor precision, and unsatisfactory adhesion in existing technologies, and meet the growing production demands of precision casting manufacturers.

The lifting cylinder 54 is used to drive the pressure roller 56 to move closer to or further away from the casting body 6.

[0040] Working principle:

[0041] Before starting the equipment, the operator adjusts the distance between the limiting blocks 33 by adjusting the shaft 34 according to the size specifications of the casting body 6, ensuring that casting bodies 6 of different sizes can be stably limited on the conveyor belt 32. At the same time, the negative pressure parameters of the negative pressure generating device 442 are adjusted according to the material and size of the label to ensure that the adsorption mechanism 44 can stably pick up the label. In addition, the label roll 24 needs to be placed on the label roll mounting tray 22, and the label roll 24 needs to be passed around the guide roller 25, pass through the label separation block 26, and then the end of the backing paper is fixed on the recycling tray 23 to complete the setting of the label conveying path.

[0042] After the equipment is started, the recycling tray 23 begins to rotate under the drive of the motor, and the resulting traction force drives the label roll 24 to rotate on the label roll mounting tray 22. During the traction process, the label roll 24 passes through multiple guide rollers 25 in sequence. The guide rollers 25, through reasonable layout and angle settings, accurately guide the label conveying path, so that the labels can be smoothly and accurately conveyed towards the label separation block 26.

[0043] As the label roll 24 passes over the label separating block 26, the label separates from the backing paper because the label separating block 26 has an inclined surface or a separating blade at a specific angle. The separated label waits for the adsorption mechanism 44 to adsorb it, and the backing paper is continuously wound up by the recycling tray 23 after adsorption. As the recycling tray 23 rotates, the backing paper is continuously wrapped around the recycling tray 23 until all the labels on the label roll 24 are used up.

[0044] The operator places the casting body 6 on the conveyor belt 32, which starts to rotate under the drive of the motor, moving the casting body 6 along the conveying direction of the conveyor belt 32. The limiting blocks 33 symmetrically arranged on both sides of the conveyor belt 32 restrict the position of the casting body 6 from both sides, preventing the casting from shifting during conveying and ensuring that the casting can be stably conveyed along the predetermined path.

[0045] As the casting body 6 moves with the conveyor belt 32, the photoelectric sensor 35 mounted on the mounting bracket 31 continuously operates. When the casting body 6 blocks the light from the photoelectric sensor 35, the photoelectric sensor 35 immediately sends a signal, which is transmitted to the equipment's control system. According to the preset program and algorithm, the control system controls the conveyor belt 32 to stop rotating, so that the casting body 6 is precisely positioned below the labeling mechanism 4, awaiting label application.

[0046] When the control system receives a signal that the casting body 6 has reached the designated position, the X-axis moving module 41 starts working, driving the adsorption mechanism 44 to move along the X-axis to directly above the label. Next, the Z-axis moving module 42 starts, driving the adsorption mechanism 44 to descend along the Z-axis, causing the adsorption block 444 to gradually approach the label. When the adsorption block 444 reaches a suitable distance from the label surface, the negative pressure generating device 442 starts, generating negative pressure through the air passage 443 at the adsorption holes 445 on the adsorption block 444. This negative pressure suction firmly adheres the label to the adsorption block 444.

[0047] After the label is attracted, the X-axis moving module 41 and the Z-axis moving module 42 work together again to drive the adsorption mechanism 44 to move the label from the label conveying position to above the casting body 6. Then, the Z-axis moving module 42 slowly descends, bringing the label on the adsorption block 444 closer to the surface of the casting body 6. When the label contacts the surface of the casting body 6, the negative pressure generating device 442 gradually reduces the negative pressure, causing the label to separate from the adsorption block 444. At the same time, using the label's own adhesiveness and slight pressure, the label is accurately attached to the designated position on the casting body 6.

[0048] After the label is affixed, the casting body 6 is conveyed a further distance by the conveyor belt 32. Then, the lifting cylinder 54 starts to operate, driving the roller frame 55 and the pressure roller 56 to descend vertically. As the pressure roller 56 gradually approaches the surface of the casting body 6, when the pressure roller 56 contacts the label surface, the lifting cylinder 54 stops descending and maintains a certain pressure according to the preset pressure parameters, so that the pressure roller 56 is tightly attached to the label.

[0049] Next, the reciprocating cylinder 52 is activated, driving the pressure roller 56 to reciprocate along the surface of the casting body 6. During the reciprocating movement, the pressure roller 56 applies uniform pressure to the label by rolling, squeezing out the air between the label and the casting body 6, effectively reducing the generation of air bubbles. At the same time, through repeated reciprocating compaction, the edge of the label is fully adhered to the casting body 6, preventing any lifting and ensuring that the label is firmly and flatly attached to the casting body 6, completing the entire labeling process.

[0050] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
