[0040] Referring to Figs. 1-5 The turnover waste removing device provided by the application.

[0041] Embodiment 1

[0042] comprises:

[0043] The turnover waste removing device comprises:

[0044] The carrier plate 1 is used to fix the product to be removed of waste;

[0045] The first mounting portion is provided with the waste removing module 2, and the waste removing module 2 comprises at least one negative pressure unit 3, and the negative pressure unit 3 is formed with the airflow channel 4 penetrating through the upper and lower portions;

[0046] The second mounting portion is arranged above the waste removing module 2, and the carrier plate 1 is fixedly mounted on the second mounting portion, so that the spatial position of the carrier plate 1 is adjusted by the second mounting portion;

[0047] The first mounting portion and the second mounting portion are configured to adjust the carrier plate 1 and the negative pressure unit 3 to a relative position, wherein the relative position is that the product to be removed of waste faces the negative pressure unit 3, and the gap between the carrier plate 1 and the negative pressure unit 3 is within a set range;

[0048] During waste removing, the airflow channel 4 forms downward airflow through the negative pressure unit 3, so that the gap between the carrier plate 1 and the negative pressure unit 3 on both sides of the airflow channel 4 forms airflow, which is collected to flow downwardly to the airflow channel 4.

[0049] In the present application, the workpiece to be processed is adsorbed and fixed on the carrier plate 1, and the workpiece to be processed is subjected to laser cutting by laser to form a waste removal product, which includes a pattern retention area that needs to be retained and waste to be removed. In this process, dust will inevitably be generated, which will accumulate on the carrier plate 1. If the dust is not cleaned, the dust will block the vacuum air path of the carrier plate 1 during long-term use of the carrier plate 1, affecting the vacuum adsorption effect and further affecting the processing.

[0050] After laser cutting of the workpiece to be processed, the carrier plate 1 carrying the waste removal product obtained after laser processing is conveyed to the turnover waste removal device of the present application, and then the carrier plate 1 is fixed on the first mounting portion, and the spatial position of the carrier plate 1 is adjusted by the first mounting portion. When removing waste, the waste removal product on the carrier plate 1 is adjusted to face the negative pressure unit 3 by the first mounting portion, and then the gap between the carrier plate 1 and the negative pressure unit 3 is adjusted to a set range. The adjustment mode can be realized by any one of the following modes:

[0051] First, the position of the negative pressure unit 3 remains unchanged, and the position of the carrier plate 1 is adjusted downward until the gap between the carrier plate 1 and the negative pressure unit 3 is within the set range.

[0052] Second, after the waste removal product on the carrier plate 1 is adjusted to face the negative pressure unit 3, the position of the waste removal product remains unchanged, and the position of the negative pressure unit 3 is adjusted upward until the gap between the carrier plate 1 and the negative pressure unit 3 is within the set range.

[0053] Based on the above structure, after starting the negative pressure unit 3, the negative pressure unit 3 can form a downward airflow in the airflow channel 4, so that an airflow is formed in the gap between the carrier plate 1 and the negative pressure unit 3 on both sides of the airflow channel 4, and is collected to flow downward in the airflow channel 4, so that the dust accumulated on the carrier plate 1 is conveyed along the airflow, and the dust accumulated on the carrier plate 1 is removed, and in this process, the waste can also be conveyed along the airflow with the dust, so that the waste can also be removed along with the dust in the process of removing the dust.

[0054] When the width of the waste removal product is large, the width of the waste removal product can be divided into a plurality of work unit areas, and each work unit area is provided with a negative pressure unit 3. The downward airflow generated by the negative pressure unit 3 arranged corresponding to each work unit area removes the dust and waste in the work unit area, ensuring that the dust accumulated on the carrier plate 1 and the waste formed after laser cutting can be removed.

[0055] Embodiment 2

[0056] The structure and principle of embodiment 2 are similar to those of embodiment 1, and the difference lies in that: Figs. 4-5As shown, a preferred structure of the negative pressure unit 3 is given, the negative pressure unit 3 comprises two air-blowing and adsorbing air knives 3-2 arranged oppositely, and a gap between the two air-blowing and adsorbing air knives 3-2 forms the airflow channel 4; the air-blowing and adsorbing air knives 3-2 are provided with air outlet channels 3-3 at the side of the airflow channel 4, and the air outlet channels 3-3 of the two oppositely arranged air-blowing and adsorbing air knives 3-2 cooperate with each other to form a downward airflow in the airflow channel 4.

[0057] In the above structure, based on Bernoulli's principle, the external air source enters the air-blowing and adsorbing air knives 3-2, and high-speed jets are generated through the air outlet channels 3-3, and the high-speed jets generated by the air outlet channels 3-3 of the two oppositely arranged air-blowing and adsorbing air knives 3-2 form a downward airflow in the airflow channel 4, which drives the gap between the air-blowing and adsorbing air knives 3-2 and the carrier plate 1 on both sides of the airflow channel 4 to form an airflow, and the airflow flows downward to the airflow channel 4.

[0058] Embodiment 3

[0059] The structure and principle of embodiment 3 are close to those of embodiment 2, and the difference lies in that a preferred structure of the air-blowing and adsorbing air knife 3-2 is given on the basis of embodiment 2. As shown, Figs. 1-3 the air-blowing and adsorbing air knife comprises an air knife body 3-21 and an arc-shaped plate 3-22; an air-blowing cavity 3-211 is arranged in the air knife body 3-21, and an air inlet 3-212 and a first air outlet slot 3-213 are arranged on the air knife body 3-21 and communicate with the air-blowing cavity 3-211, and the first air outlet slot 3-213 is arranged at the side of the air-blowing cavity 3-211 located in the airflow channel 4; the arc-shaped plate 3-22 is installed at one end of the air knife body 3-21 facing the airflow channel 4, the arc-shaped plate 3-22 is located at the upper part of the first air outlet slot 3-213, and one end of the arc-shaped plate 3-22 facing the airflow channel 4 has a downward arc.

[0060] In embodiment 3, a strip-shaped hole or a plurality of small holes arranged at intervals is arranged as the first air outlet slot at the side of the air-blowing cavity 3-211 close to the airflow channel 4. When the strip-shaped hole is used as the first air outlet slot, a strip-shaped hole with a length close to that of the air-blowing cavity can be arranged on the side wall of the air-blowing cavity as the first air outlet slot. When the plurality of small holes are used as the first air outlet slot, a plurality of strip-shaped holes with small lengths can be arranged at intervals on the side wall of the air-blowing cavity as the first air outlet slot; or a small-size hole such as a round hole or a square hole can also be used.

[0061] The air flow blown out by the first air outlet slot changes the direction of the air flow under the action of the arc-shaped plate 3-22, guides the air flow blown out by the first air outlet slot to flow downward in the air flow channel 4, and drives the air around the air flow channel 4 to flow, so as to form a negative pressure state in the air flow channel 4, so that the gap between the carrier plate 1 and the air blowing and adsorbing air knife 3-21 on both sides of the air flow channel 4 generates an air flow, and the air flow converges to flow downward in the air flow channel 4, thereby removing waste powder and waste materials.

[0062] In embodiment 3, the air knife body 3-21 is designed as an integral piece. Alternatively, as shown in the figure, the air knife body 3-21 is a split structure, and the air knife body is divided into a groove part 3-214 and a top cover plate 3-215. The top cover plate 3-215 is fixedly installed on the top of the groove part 3-214, and a blowing air cavity 3-211 is formed in the groove part 3-214, which is sealed by the top cover plate 3-215. Figs. 1-3

[0063] Embodiment 4

[0064] The structure and principle of embodiment 3 are similar to those of embodiment 4, and the difference lies in that the air knife body 3-21 is provided with an adjusting plate 3-23 which can slide up and down relative to the air knife body 3-21 on the side wall facing the air flow channel 4. The top of the adjusting plate 3-23 has a downward arc facing the air flow channel 4, and the top of the adjusting plate and the bottom of the arc-shaped plate form a second air outlet slot 3-24. The first air outlet slot and the second air outlet slot 3-24 jointly serve as an air outlet channel 3-3.

[0065] The air knife body 3-21 is provided with an adjusting hole 3-216 on the side wall facing the air flow channel 4, and the adjusting plate 3-23 is provided with an adjusting groove 3-231 corresponding to the adjusting hole 3-216. A fastener is inserted into the adjusting hole 3-216 and the corresponding adjusting groove 3-231, and the adjusting plate 3-23 is fixed on the air knife body 3-21 by the fastener.

[0066] The adjusting plate 3-23 is connected to the air knife body 3-21 in the following arrangement: the side of the air knife body 3-21 facing the adjusting plate 3-23 is provided with a sliding block, and the side of the adjusting plate 3-23 facing the air knife body 3-21 is provided with a sliding groove matched with the sliding block, and the sliding block slides up and down in the sliding groove, or the side of the air knife body 3-21 facing the adjusting plate 3-23 is provided with a sliding groove, and the side of the adjusting plate 3-23 facing the air knife body 3-21 is provided with a sliding block connected to the sliding groove, and the sliding block slides up and down in the sliding groove, thereby playing a guiding role in adjusting the gap of the second air outlet slot 3-24.

[0067] ​In the embodiment, the fixed position of the adjusting plate 3-23 on the air knife body 3-21 can be adjusted according to requirements, so as to realize the gap adjustment of the second air outlet gap. Since the air outlet channel 3-3 is divided into the second air outlet gap on the outer side and the first air outlet gap on the inner side, the size of the second air outlet gap can be adjusted according to requirements, and different jet flows with different sizes and angles are formed, so as to meet the use requirements of different working conditions.

[0068] The gap range of the second air outlet gap is 1.1mm-7.5mm; and / or the distance range of the air flow channel formed by the two air blowing and adsorbing air knives of the same negative pressure unit is 5mm-50mm.

After the tilting frame rotates so that the product to be de-wasted faces the de-wasting module, the lifting mechanism drives the tilting frame to move downward until the gap between the carrier plate and the negative pressure unit is within the set range.
