Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, and more specifically to a flexible labeling mechanism with spring buffer. Background Technology

[0002] With the continuous development of automation technology, the sheet metal processing industry has widely adopted automated labeling systems to achieve material tracking, identification, and production process management. The labeling process, as a key link in automated sheet metal processing lines, typically involves labeling mechanisms affixing labels to the sheets to be processed, enabling subsequent process identification, warehouse management, and after-sales traceability.

[0003] Existing labeling equipment generally includes an adsorption structure for absorbing labels and a drive mechanism for moving the adsorption structure. The labeling action is usually completed by a cylinder. However, in practical applications, due to the uncontrollable pressure output by the cylinder and the diversity of material properties, conventional labeling mechanisms are prone to label damage due to excessive pressure during labeling, and may even cause indentations or damage to softer materials. In addition, the rigid impact caused by the frequent and prolonged operation of the cylinder can easily lead to fatigue or deformation of the labeling mechanism's structural components, affecting the equipment's service life and labeling accuracy. Therefore, there is an urgent need for a flexible labeling mechanism with a buffer structure, gentle labeling action, strong adaptability, and the ability to extend the equipment's service life, in order to improve labeling quality and system stability. Utility Model Content

[0004] In view of this, the present invention provides a flexible labeling mechanism with spring buffer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flexible labeling mechanism with spring buffer includes a mechanism body movably connected to a main beam. The mechanism body includes a reducer, a labeling cylinder, a rotary cylinder, a connecting plate, and an adsorption block. The reducer drives the mechanism body to move horizontally on the main beam. The labeling cylinder is connected to the rotary cylinder and can drive it to move vertically. The rotary cylinder is connected to and can drive the connecting plate and the adsorption block to rotate horizontally. The connecting plate is disposed between the rotary cylinder and the adsorption block, and the connecting plate and the adsorption block are connected by multiple spring-loaded screws to achieve elastic buffering.

[0007] In the preferred embodiment, the connecting plate is provided with multiple through holes, and a plug screw is inserted into the through hole. The threaded end of the plug screw is connected to the adsorption block. The diameter of the plug screw head is larger than the diameter of the through hole, and the screw head is stuck on the top surface of the connecting plate. The spring is set between the connecting plate and the adsorption block to achieve elastic floating.

[0008] In the preferred embodiment, the spring is a compression spring, and the pre-compression of the spring is less than its ultimate compression, ensuring that it will not be completely crushed when labeling and guaranteeing sufficient elasticity.

[0009] In a preferred embodiment, the mechanism body is provided with a vertical fixing plate for fixing and connecting the labeling cylinder, a connecting bracket is provided between the piston rod end of the labeling cylinder and the rotary cylinder, and a vertically arranged vertical slide rail and a vertical slider are connected between the vertical fixing plate and the connecting bracket.

[0010] In a preferred embodiment, the mechanism body is provided with a horizontal fixing plate for fixing the reducer, the horizontal fixing plate is connected to a vertical fixing plate, and the vertical fixing plate is provided with a plurality of horizontal sliders on the side near the horizontal fixing plate.

[0011] In the preferred embodiment, the labeling cylinder is an electrically controlled cylinder, which is controlled by a PLC or other control system to extend and retract, thereby achieving precise positioning during the labeling process.

[0012] In a preferred embodiment, the adsorption block is made of a lightweight alloy material and has multiple vacuum suction cups or suction holes at its bottom for efficiently adsorbing labels of different sizes and materials.

[0013] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This labeling mechanism effectively absorbs the impact force generated during labeling by incorporating a spring-loaded buffer structure between the connecting plate and the adsorption block. This prevents damage to softer materials caused by excessive cylinder output pressure, improving labeling adaptability and stability. The elastic buffer structure reduces rigid impact between the cylinder and other components, effectively mitigating mechanical wear and fatigue and extending the overall equipment's service life. The adsorption block, driven by a rotary cylinder, can rotate ±90° horizontally, adapting to labeling needs in different positions and directions, enhancing labeling flexibility and compatibility.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] Please refer to a flexible labeling mechanism with spring cushioning. Figure 1-3The labeling mechanism is used to affix labels to the boards that need to be processed. The labeling process is widely used in automated board processing, serving functions such as material tracking and identification, automated equipment identification, production process tracking, and after-sales and quality inspection traceability. The labeling process is usually automated. The general flow is that the labeling machine receives the labeling instruction, absorbs the printed label, moves it onto the board for pressing, and returns to its original position for the next labeling cycle. This utility model includes a mechanism body 100, which is movably connected to the main machine beam. The beam is generally movably connected to the machine tool, and the movable structure of the mechanism body 100 enables horizontal movement in both the X and Y axes. For example, the process of moving from the standby position to the labeling position requires both movement methods to be achieved simultaneously. The machine tool and beam are not shown in the attached drawings. The mechanism body 100 includes a reducer 110, a labeling cylinder 120, a rotary cylinder 130, a connecting plate 150, and an adsorption block 140. The reducer 110 is used to drive the main body 100 to move horizontally on the main beam. The reducer 110 is a motor with speed reduction. The labeling cylinder 120 is connected to the rotary cylinder 130 and can drive it to move vertically. The rotary cylinder 130 is connected to and can drive the connecting plate 150 and the adsorption block 140 to rotate horizontally. When labeling, the labeling cylinder 120 drives the interconnected rotary cylinder 130 and the adsorption block 140 to press down to complete the labeling. The rotary cylinder 130 can realize the ±90° rotation of the adsorption block 140 in the horizontal direction to adapt to different labeling angles. The connecting plate 150 and the adsorption block 140 are connected by multiple screws 152 fitted with springs 151 to achieve elastic buffering. Since the adsorption block 140 with the label needs to contact the board, if the air pressure is unstable and the force of the cylinder is too great, this hard contact may damage the relatively soft board. Using the spring 151 instead of the cylinder to directly output force as the labeling pressure method reduces the impact on the board during the labeling process and can effectively protect the material. In addition, if the machine is subjected to excessive force for a long time, it will also affect its service life. Therefore, this labeling mechanism with elastic buffering structure can extend the service life of the equipment.

[0024] Furthermore, the connecting plate 150 is provided with multiple through holes 153, and a plug screw 152 is inserted into the through hole 153. The threaded end of the plug screw 152 is connected to the adsorption block 140. The diameter of the screw head of the plug screw 152 is larger than the diameter of the through hole 153. Therefore, the screw head of the plug screw 152 is locked on the upper surface of the connecting plate 150. The main body of the plug screw 152 is inserted into the through hole 153 and extends downward to connect to the adsorption block 140. A spring 151 is provided between the connecting plate 150 and the adsorption block 140 to achieve elastic floating. The upper and lower ends of the spring 151 contact the connecting plate 150 and the adsorption block 140 respectively. When the bottom of the adsorption block 140 is pressed, it can move upward elastically. Spring 151 is a compression spring. The pre-compression of spring 151 is less than its ultimate compression, ensuring that when labeling, after the connecting plate 150 and the adsorption block 140 move down together, the adsorption block 140 maintains continuous contact with the board and elastically retracts, without being completely crushed, ensuring sufficient elasticity and avoiding excessive pressure that could damage the relatively soft board material.

[0025] Furthermore, the mechanism body 100 is provided with a vertical fixing plate 160 for fixing and connecting the labeling cylinder 120. A connecting bracket 131 is provided between the piston rod end of the labeling cylinder 120 and the rotary cylinder 130. A vertically arranged vertical slide rail 161 and a vertical slider 162 are provided between the vertical fixing plate 160 and the connecting bracket. The connection of the vertical slide rail 161 and the vertical slider 162 can ensure that the labeling cylinder 120 pushes the rotary cylinder 130 to move up and down stably and smoothly, ensuring labeling stability. The cylinder body of the labeling cylinder 120 is connected and fixed on the vertical fixing plate 160. Since the rotary cylinder 130 and the adsorption block 140 need to avoid each other in position, the connecting bracket 131 can be used as the connection part between the rotary cylinder 130 and the labeling cylinder 120. The overall structure of the mechanism body 100 can be rationalized by changing the structure. The mechanism body 100 is provided with a horizontal fixing plate 170 for fixing the reducer 110. The reducer 110 is fixed by the horizontal fixing plate 170. The rotating shaft of the reducer 110 passes through the horizontal fixing plate 170 and extends downward. The rotating shaft is provided with a gear. The horizontal fixing plate 170 is connected to a vertical fixing plate 160. The vertical fixing plate 160 is provided with two horizontal sliders 141 on the side near the horizontal fixing plate 170. Under normal circumstances, the machine tool crossbeam is provided with slide rails that match the horizontal sliders 141 and racks that match the gears on the reducer 110, so that the reducer 110 can drive the mechanism body 100 to move horizontally on the crossbeam.

[0026] Furthermore, the labeling cylinder 120 is an electrically controlled cylinder. Electrically controlled cylinders are the most common, have fast response, and are easy to program. Its extension and retraction are controlled by a PLC to achieve precise positioning during the labeling process. Generally, the PLC also controls the operation of various components, such as vacuum adsorption control, cylinder positioning control, position detection, or fault alarms. The adsorption block 140 is made of lightweight alloy material and has multiple suction holes at its bottom for efficiently adsorbing labels of different sizes and materials. The lightweight metal material of the adsorption block 140 reduces weight, improves response speed, and provides high strength, rigidity, and resistance to deformation, ensuring sufficient support for impacts and repeated labeling actions. The adsorption block 140 has an internal tube connecting to the suction holes, connected to an air pipe through a side opening. This air pipe connects to a vacuum pump to achieve the adsorption function. Labeling machines typically have a label printer. After the label is printed, the main body 100 moves to the label location. After the adsorption block 140 adsorbs the label, the main body 100 moves to the desired labeling position on the board for labeling.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
