Description

Technical Field

[0001] The invention relates to a laser label engraving machine, in particular to a size-variable feeding positioning device and a laser label engraving machine with the feeding positioning device. Background Art

[0002] With the rapid development of industry, many factories are gradually introducing automated and semi-automated equipment to effectively reduce manpower, increase production capacity, and improve yield rates. Within these automated and semi-automated processes, materials often need to be moved between different process stations. Therefore, materials are often transferred in multiple quantities at a time, such as on tapes, trays, or trays. Furthermore, to reduce restocking time, automated and semi-automated equipment often includes a holding area before the starting station to store multiple materials awaiting processing. Conveyors then sequentially transfer these materials to the processing area for the required processing.

[0003] For example, existing laser label engraving machines typically consist of a feeder and a laser head. The feeder inserts the workpiece under the laser head and positions it, allowing the laser head to process the workpiece. However, the feeder of existing laser label engraving machines is typically designed for specific dimensions. Therefore, changes in workpiece size require either a new workpiece design with a compatible size or a replacement feeder with a compatible size.

[0004] Therefore, existing laser label engraving machines have poor compatibility with materials of different specifications and are quite inconvenient to use. They are not suitable for small-volume label engraving. Summary of the Invention

[0030] Figure 1 FIG is a perspective diagram of the laser label engraving machine 11 of the present invention. Figure 1 One embodiment of the present invention provides a laser label engraving machine 11 for continuously feeding a plurality of workpieces 20a and engraving labels on each of the workpieces 20a using a laser beam. In this embodiment, the laser label engraving machine 11 includes a main body 100, a feed positioning device 12, and a laser head 600. Specifically, the feed positioning device 12 includes a preparation table 200, a workbench 300, a conveying mechanism 400, and a positioning mechanism 500.

[0031] The material preparation table 200 is disposed within the main body 100 and is used to support the materials 20a, which are stacked on the material preparation table 200. A workbench 300 is disposed within the main body 100 for laser engraving operations. A conveying mechanism 400 is used to transport one of the materials 20a on the material preparation table 200 to the workbench 300. Specifically, the material 20a stacked on the bottom layer is transferred from the material preparation table 200 to the workbench 300.

[0032] See Figures 2 to 4In this embodiment, the conveying mechanism 400 includes a transmission shaft 410, a drive motor 420, a first drive wheel 431, a second drive wheel 432, a first driven wheel 441, a second driven wheel 442, a first belt 451, and a second belt 452. The drive motor 420 is connected to the transmission shaft 410, and a longitudinal keyway 411 is provided on one side of the transmission shaft 410. The first drive wheel 431 and the second drive wheel 432 are coaxially disposed on the transmission shaft 410. Specifically, the transmission shaft 410 connects the first drive wheel 431 and the second drive wheel 432 in series. A first sleeve 435 is disposed within the first drive wheel 431 and is sleeved on the transmission shaft 410. A second sleeve 436 is disposed within the second drive wheel 432 and is sleeved on the transmission shaft 410.

[0033] See Figures 3 to 6 The first driving wheel 431 has a first sliding key 433 that engages with the longitudinal key groove 411, thereby driving the transmission shaft 410. The second driving wheel 432 has a second sliding key 434 that engages with the longitudinal key groove 411 to drive the transmission shaft 410, thereby driving the second driving wheel 432 to drive the transmission shaft 410.

[0034] See Figure 1 and Figure 2 The first driven wheel 441 and the second driven wheel 442 are coaxially arranged. Specifically, the first drive wheel 431 and the second drive wheel 432 are configured to correspond to one of the material preparation platform 200 and the work platform 300, and the first driven wheel 441 and the second driven wheel 442 are configured to correspond to the other of the material preparation platform 200 and the work platform 300. The first belt 451 is wrapped around the first drive wheel 431 and the first driven wheel 441, connecting between the material preparation platform 200 and the work platform 300. The second belt 452 is wrapped around the second drive wheel 432 and the second driven wheel 442, connecting between the material preparation platform 200 and the work platform 300. The first belt 451 and the second belt 452 are arranged parallel to each other and extend to the bottom of the material preparation platform 200 to contact the material parts 20a stacked on the bottom layer. The driving motor 420 can drive the transmission shaft 410 to rotate and drive the first driving wheel 431 and the second driving wheel 432 to rotate. When the first driving wheel 431 and the second driving wheel 432 rotate, they can respectively push the first wheel belt 451 and the second wheel belt 452, and the material 20a stacked on the bottom layer is carried by the first wheel belt 451 and the second wheel belt 452 and transported to the workbench 300 by the first wheel belt 451 and the second wheel belt 452.

[0035] See Figure 1 、 Figure 2 and Figure 4The positioning mechanism 500 is disposed on the workbench 300 and includes an actuating screw 510, a first clamp 521, and a second clamp 522. A first thread segment 511 and a second thread segment 512 are provided on the side of the actuating screw 510. The first thread segment 511 and the second thread segment 512 rotate in opposite directions. The first thread segment 511 and the second thread segment 512 extend from the middle of the actuating screw 510 to both ends of the actuating screw 510, respectively.

[0036] See Figure 2 and Figure 4 The first fixture 521 has a first nut 531 engaged with the first thread segment 511, and the second fixture 522 has a second nut 532 engaged with the second thread segment 512. The material 20a transported to the workbench 300 is positioned between the first fixture 521 and a second fixture 522.

[0037] See Figure 4 and Figure 7 The actuating screw 510 is provided with a handle 501 for a user to operate and rotate the actuating screw 510. When the actuating screw 510 is rotated, the first thread segment 511 and the second thread segment 512 respectively drive the first nut 531 and the second nut 532 to move closer together or farther apart. In this way, the distance between the first clamp 521 and the second clamp 522 can be adjusted according to the size of the input material 20a.

[0038] The first belt 451 and the second belt 452 are disposed between the first fixture 521 and the second fixture 522. Thus, the first fixture 521 and the second fixture 522 support the conveyed material 20a, while the first fixture 521 and the second fixture 522 position the outer edge of the material 20a. The first drive wheel 431 is connected to the first fixture 521, and the first driven wheel 441 is pivotally mounted on the first fixture 521. Specifically, the first fixture 521 engages the first drive wheel 431, so the first belt 451 moves synchronously with the first fixture 521. The second drive wheel 432 is connected to the second fixture 522, and the second driven wheel 442 is pivotally mounted on the second fixture 522. Specifically, the second fixture 522 engages the second drive wheel 432, so the second belt 452 moves synchronously with the second fixture 522.

[0039] See Figure 1 The laser head 600 is disposed on the main body 100 and arranged above the workbench 300 . The laser head 600 can emit a laser beam downward, which is used to laser engrave the material 20 a located on the workbench 300 .

[0040] See Figure 1 and Figure 8The feed positioning device 12 of the laser label engraving machine 11 of the present invention has a variable-size positioning mechanism 500. The positioning mechanism 500 can move on the conveying mechanism 400 to change the size and adapt to materials 20a, 20b of different sizes, and the actuation of the conveying mechanism 400 is not affected by the actuation of the positioning mechanism 500.

[0041] The above embodiments are merely preferred embodiments for the purpose of fully illustrating the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention.
