Description

Technical Field

[0001] The utility model relates to the technical field of marking, and particularly relates to a marking device. Background Art

[0002] Some metal products require marking at a certain position on the surface, and the marking content includes the material, production date, serial number, etc. of the product. However, due to the relatively harsh use environment of some metal products, if the stroke depth of the marking is shallow and the width is narrow, its durability will be greatly reduced.

[0003] In order to make the depth of the marking reach 0.4 mm - 0.5 mm, three methods are often used:

[0004] One: Using die pressing. The disadvantage of this method is that the die needs to be replaced every time a piece is pressed, which is not only prone to errors but also difficult to achieve efficient operation.

[0005] Two: Milling concave characters with a milling machine. The disadvantage of this method is the large investment.

[0006] Three: Using a small pneumatic marking machine. The disadvantage of this method is that for each piece produced, it needs to be manually carried several times, and the operation intensity is relatively high. Content of the Utility Model

[0007] The utility model provides a marking device, which solves or partially solves the technical problems of low efficiency, high cost, and high operation intensity in marking metal products in the prior art.

[0035] In the specific implementation manner of the present application, since a plurality of first conveying rollers 2 are rotatably arranged on the first support 1, the plurality of first conveying rollers 2 are arranged in parallel at intervals, the gantry 3 is arranged on the first support 1, the marking assembly 4 is slidably arranged on the gantry 3, one end of the first lifting member 5 is connected to the first support 1, and the other end is connected to the marking assembly 4. Therefore, when the metal workpiece 6 is placed on the first conveying rollers 2, the staff can push the metal workpiece 6 to move on the first conveying rollers 2 until the metal workpiece 6 reaches the marking position, without manual handling, and the operation intensity is low. When the metal workpiece 6 reaches the marking position, the first lifting member 5 is started, and the first lifting member 5 drives the marking assembly 4 to descend on the gantry 3 until the marking assembly 4 reaches the working position, and the marking assembly 4 marks the metal workpiece 6, with low cost. At the same time, the efficiency of marking the metal workpiece 6 can be improved. When the marking assembly 4 finishes marking the metal workpiece 6, the first lifting member 5 is started, and the first lifting member 5 drives the marking assembly 4 to rise on the gantry 3, and the marking assembly 4 leaves the working position. At this time, the staff can push the metal workpiece 6 to move on the first conveying rollers 2 until the metal workpiece 6 leaves the marking position, without manual handling, and the operation intensity is low, and the efficiency of marking the metal workpiece 6 can also be improved.

[0036] In some embodiments, the marking assembly 4 includes: a mounting bracket 4-1 and a pneumatic marking machine 4-2.

[0037] The mounting bracket 4-1 is slidably arranged on the gantry 3 and is connected to the first lifting member 5.

[0038] The pneumatic marking machine 4-2 is arranged on the mounting bracket 1. In this embodiment, a marking head 4-21 is provided on the pneumatic marking machine 4-2 to mark the metal workpiece 6 through the marking head 4-21.

[0039] In this embodiment, when the metal workpiece 6 reaches the marking position, the first lifting member 5 is started, and the first lifting member 5 drives the mounting bracket 4-1 to descend on the gantry 3. The mounting bracket 4-1 drives the pneumatic marking machine 4-2 to act until the pneumatic marking machine 4-2 reaches the working position, and the marking head 4-21 of the pneumatic marking machine 4-2 marks the metal workpiece 6, with low cost. At the same time, the efficiency of marking the metal workpiece 6 can be improved. When the marking head 4-21 of the pneumatic marking machine 4-2 finishes marking the metal workpiece 6, the first lifting member 5 is started, and the first lifting member 5 drives the mounting bracket 4-1 to rise on the gantry 3, and the mounting bracket 4-1 drives the pneumatic marking machine 4-2 to leave the working position.

[0040] In this embodiment, a connecting member 4-3 is provided on the end face of the pneumatic marking machine 4-2 facing the first conveying roller 2, and at least one electromagnet 4-4 is provided on the end face of the connecting member 4-3 facing the first conveying roller 2 to support the electromagnet 4-4 through the connecting member 4-3.

In this embodiment, a start-stop switch 8 is provided on the gantry 3 to control the energization and de-energization of the electromagnet 4-4 through the start-stop switch 8.

[0041] In this embodiment, when the pneumatic marking machine 4-2 reaches the working position, the connecting member 4-3 drives the electromagnet 4-4 to contact the metal workpiece 6. At this time, the electromagnet 4-4 is energized, and the electromagnet 4-4 generates magnetism to adsorb the electromagnet 4-4 on the metal workpiece 6, so that the pneumatic marking machine 4-2 is adsorbed on the surface of the metal workpiece 6, and the pneumatic marking machine 4-2 and the metal workpiece 6 are connected as a whole, avoiding the position of the pneumatic marking machine 4-2 on the metal workpiece 6 from changing, and ensuring the position of the marking of the pneumatic marking machine 4-2 is determined. When the marking assembly 4 finishes marking the metal workpiece 6, the electromagnet 4-4 is de-energized, the electromagnet 4-4 demagnetizes, and the electromagnet 4-4 no longer adsorbs the metal workpiece 6, so that the first lifting member 5 can drive the pneumatic marking machine 4-2 away from the working position, facilitating the staff to push the metal workpiece 6 to move on the first conveying roller 2.

[0042] In this embodiment, in order to facilitate the sliding of the mounting bracket 4-1 on the gantry 3, a slider is provided on the mounting bracket 4-1, and a slide rail 3-1 is provided on the gantry 3.

When the marking assembly 4 finishes marking the metal workpiece 6, the pushing member 10 is started, and the action end of the pushing member 10 separates from the side of the metal workpiece 6 to release the metal workpiece 6.

[0045] In this embodiment, the first guide member 9 and the pushing member 10 are opposite to each other. The first guide member 9 can be installed on the gantry 3, and the first guide member 9 is supported by the gantry 3. The fixed end of the pushing member 10 is arranged on the first bracket 1, and the pushing member 10 is supported by the first support member 1. The pushing member 10 can be a pneumatic cylinder, and a second valve 11 is arranged on the first bracket 1 to control the telescopic movement of the pneumatic cylinder.

[0046] In this embodiment, the first guide member 9 can be a guide wheel. When the moving end of the pushing member 10 is separated from the side of the metal workpiece 6, the staff pushes the metal workpiece 6 to move on the first conveying roller 2, and the movement of the metal workpiece 6 is guided by the guide wheel so as to facilitate the metal workpiece 6 to leave the marking position.
