Description

Technical Field

[0001] The utility model relates to the technical field of laser marking equipment, in particular to a sub-frame laser marking device. Background Art

[0002] The subframe parts in the car are manufactured by low-pressure casting production process. Usually, the subframe needs to be marked on its surface after casting, so as to facilitate traceability in the event of defects.

[0028] A subframe laser marking device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0029] Reference Figure 1 and Figure 2 A sub-frame laser marking device according to an embodiment of the utility model includes a frame, a marking mechanism and a positioning bracket.

[0030] The frame includes a workbench 100 , and the top surface of the workbench 100 is used to place the product 300 to be marked.

[0031] In some embodiments of the present invention, a vertical board 250 is disposed on the top of the workbench 100 , a horizontal board 260 is disposed on the top of the vertical board 250 , and a light tube 270 is disposed on the horizontal board 260 .

[0032] Therefore, the lamp tube 270 is used to illuminate the workbench 100 , so that the staff can observe the marking position of the product 300 to be marked.

[0033] In some embodiments of the present invention, a vertical plate 250 is disposed on the top of the workbench 100 , a horizontal plate 260 is disposed on the top of the vertical plate 250 , and a fan 280 is disposed on the horizontal plate 260 .

[0034] Therefore, the fan 280 can supply air to the product 300 to be marked on the workbench 100 , which can reduce the temperature of the product after die-casting, making it convenient for the staff to mark the product 300 to be marked.

[0035] In some embodiments of the present invention, a storage box 290 is provided at the bottom of the workbench 100, and the laser marking body 110 is stored inside the storage box 290. Therefore, the storage box 290 can prevent the laser marking body 110 from being interfered by the outside world and prevent the laser marking body 110 from being damaged.

[0036] The marking mechanism includes a laser marking body 110 disposed under the workbench 100, a laser marking head 120 for marking the product 300 to be marked, and an optical fiber electrically connecting the laser marking body 110 and the laser marking head 120. The laser marking head 120 can be handheld.

[0037] Therefore, the laser marking body 110 is connected to the laser marking head 120 through the optical fiber line. During marking, the operator places the product 300 to be marked on the top surface of the workbench 100. The operator can freely arrange the position of the optical fiber line, so that the operator can freely move the position of the laser marking head 120. The laser marking head 120 can mark the product 300 to be marked. The marking mechanism has a simple structure and low manufacturing cost.

[0038] Among them, the positioning bracket includes a connecting frame 130 and a positioning frame 140 detachably connected to the connecting frame 130, the connecting frame 130 is connected to the laser marking head 120, the positioning frame 140 is used to position the laser marking head 120 on the product 300 to be marked, and a laser channel 150 is arranged between the connecting frame 130 and the positioning frame 140, the laser channel 150 extends along the direction of the laser energy emitted by the laser marking head 120, and the laser channel 150 accommodates the passage of the laser energy emitted by the laser marking head 120.

[0039] The connecting frame 130 is connected and fixed to the laser marking head 120, and the positioning frame 140 is used to accurately position the laser marking head 120 on the product 300 to be marked. The laser energy emitted by the laser marking head 120 can pass through the laser channel 150 to mark the product 300 to be marked, and there is no need to use a positioning fixture to position the product 300 to be marked. It is more convenient and quick to move the laser marking head 120, which reduces the labor intensity of the operator in carrying and positioning the product 300 to be marked. At the same time, it ensures that the marking position of each product is consistent, avoiding the problem of offset and skew of the marking position. Furthermore, the positioning frame 140 and the connecting frame 130 can be disassembled. For products of different specifications, the positioning frame 140 of the corresponding specifications can be quickly replaced, so that the laser marking head 120 can mark products of different specifications.

[0040] In some embodiments of the present invention, referring to Figure 3 The connecting frame 130 has an annular ring 160 and a connecting strip 170 connected to the end of the annular ring 160 . The connecting strip 170 is distributed along the outer circumference of the annular ring 160 , and a laser channel 150 is formed on the inner side of the annular ring 160 .

[0041] Therefore, the connecting frame 130 composed of the annular ring 160 and the connecting strip 170 has a simple structure, does not increase the weight of the laser marking head 120, and is convenient for operators to move the laser marking head 120. The connecting frame 130 can also prevent operators from extending their hands into the range of the laser channel 150, greatly improving the safety of the marking operation.

[0042] In a further embodiment of the present invention, a connecting plate 180 is provided at one end of the annular ring 160 away from the connecting strip 170 , and the annular ring 160 is connected to the laser marking head 120 via the connecting plate 180 , so that the connecting frame 130 is firmly connected to the laser marking head.

[0043] In a further embodiment of the present invention, the positioning frame 140 has a support plate 190 . The support plate 190 is provided with positioning holes 200 . A plurality of connecting strips 170 are accommodated inside the positioning holes 200 .

[0044] Therefore, the positioning frame 140 is accurately positioned on the connecting frame 130 by using the positioning hole 200 , so that the positioning frame 140 can accurately position the laser marking head 120 on the product 300 to be marked.

[0045] In a further embodiment of the present invention, the connection strip 170 is provided with an overlap portion 210 , the overlap portion 210 is overlapped on the support plate 190 , and the overlap portion 210 and the support plate 190 are connected by bolts.

[0046] When installing the positioning frame 140, the connecting frame 130 is overlapped on the positioning frame 140 using the overlap portion 210, and then the overlap portion 210 and the support plate 190 are connected and fixed using bolts, so that the installation of the positioning frame 140 is more convenient.
