The following description refers to the accompanying drawings.

Referring to fig. 1 to 5, fig. 1 is a schematic view of a component blowing-off device according to an embodiment of the present invention; fig. 2 is a schematic view of the interior of the first purge chamber in an embodiment of the invention; FIG. 3 is a schematic view of the exterior of the first purge chamber in an embodiment of the invention; FIG. 4 is a schematic view of the interior of a second blow-down chamber in an embodiment of the present invention; fig. 5 is a schematic view of the interior of the second chamber according to an embodiment of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a part blowing device, which includes a first chamber 100, wherein the first chamber 100 has a feeding hole 101 and a discharging hole 102; a first blow-off chamber 200, a second blow-off chamber 300, a first carrying mechanism 400 and a second carrying mechanism 500 are arranged in the first chamber 100; the first blow-off cavity 200 is used for blowing off the parts 204, and the second blow-off cavity 300 is used for blowing off the material tray 700; the first conveying mechanism 400 is used for conveying the parts 204 to be cleaned from the feeding hole 101 to the first cleaning chamber 200, and for conveying the cleaned parts 204 from the first cleaning chamber 200 to the discharging hole 102; the second carrying mechanism 500 is used for carrying the material tray 700 to be cleaned from the material inlet 101 to the second cleaning chamber 300, and for carrying the cleaned material tray 700 from the second cleaning chamber 300 to the material outlet 102. With such a configuration, the following advantageous effects can be obtained: firstly, the material tray 700 is also blown clean, so that the parts 204 are prevented from being secondarily polluted by the unclean material tray 700 when being put back to the material tray 700; secondly, the blowing operation of the material tray 700 and the parts 204 is performed simultaneously, so that the total blowing time is shortened; third, by providing the first chamber 100 to separate the parts 204 and the tray 700 from the outside, the air in the first chamber 100 can be cleaned in advance, thereby preventing the parts 204 and the tray 700 from being secondarily contaminated by contaminants floating in the untreated air during the transfer process.

Referring to fig. 1, in a preferred embodiment, at least two first blow-off chambers 200 are disposed in the first chamber 100. Although the blowing time of one material tray 700 is longer than that of one part 204, the arrangement of more than two first blowing cavities 200 in the first chamber 100 can be further optimized by considering the blowing time and the quantity ratio of the two parts, so that the total time for blowing out the parts 204 is approximately equal to that for blowing out the material tray 700, the waiting time is reduced, and the total blowing time is shortened. In one embodiment, the first transfer mechanism 400 is a six-axis robot, which is designed to take into account the variety of parts 204, the variety of placement positions, and the need to transfer the parts 204 to multiple first purge chambers 200, thereby requiring a high degree of freedom; the second transfer mechanism 500 is a four-axis robot, and since it is sufficient to transfer the material tray 700 using the four-axis robot, no more degrees of freedom are required. In other embodiments, other structures may be selected as the first and second conveying mechanisms 400 and 500.

Preferably, an openable and closable first sealing sliding door is arranged on the feeding port 101, an openable and closable second sealing sliding door is arranged on the discharging port 102, and the first sealing sliding door and the second sealing sliding door are both configured to be closed at a time outside the transportation and delivery. In this manner, a better seal of first chamber 100 may be maintained, thereby further ensuring that parts 204 and tray 700 are not contaminated by contaminants floating in the untreated air during handling. It should be understood that in the present embodiment, the first sliding sealing door and the second sliding sealing door are translated to one side and are driven pneumatically, but other arrangements may be selected, such as opening and closing by translating to two sides, driving by a motor, etc. The opening and closing manner and the driving manner, which are capable of facilitating the first carrying mechanism 300 and the second carrying mechanism 400 to grasp the parts 204 and the material tray 700 in the opened state and maintaining the good sealing performance of the first chamber 100 in the closed state, should be considered as the protection scope of the present claims. The specific structure and arrangement thereof may be configured by those skilled in the art according to the common general knowledge in the art, and will not be described in detail herein.

Referring to fig. 2, in an embodiment, a first rotating mechanism 201 and a first air knife assembly 202 are disposed in the first blowing chamber 200, an air outlet of the first air knife assembly 202 faces a rotating portion of the first rotating mechanism 201, the rotating portion has a first clamp 203, and the first clamp 203 is used for clamping a component 204. After the first conveying mechanism 300 conveys the part 204 to be cleaned into the first cleaning chamber 200, the first clamp 203 clamps the part 204, and then the first conveying mechanism 300 exits the first cleaning chamber 200, and then the first rotating mechanism 201 starts to rotate, and the first air knife assembly 202 continuously sprays high-pressure clean air. According to the actual situation of the part 204, the first rotating mechanism 201 stops after rotating an integer of 360 degrees, the first air knife assembly 202 also stops air injection, and the blowing operation is completed. Of course, in other embodiments, the first rotating mechanism 201 does not necessarily rotate at a constant speed, and the rotating direction may change halfway, and the whole process will be adaptively changed according to the specific structure and size of the part 204. In a specific embodiment, the part 204 has four aperture structures arranged parallel to each other. Four bamboo joint pipes 205 are further arranged in the first blow-clean chamber 200, and air outlets of the bamboo joint pipes 205 are arranged in a matched manner with the hole structures of the parts 204. When the first rotating mechanism 201 rotates to a specific position, the first rotating mechanism 201 stops rotating, the bamboo joint pipe 205 is exhausted, and the hole structure of the part is blown clean. In various embodiments, various secondary blow-down structures may be provided to blow down parts 204 of various configurations and sizes. It should be understood that the high pressure air source, air path conduit and control mechanism of the first air knife assembly 202 and the bamboo joint pipe 205 can be understood and configured by those skilled in the art according to the prior art, and will not be described in detail herein. The specific structure and driving manner of the first rotating mechanism 201 and the first clamp 203 can be understood and configured by those skilled in the art according to the common general knowledge in the art, and will not be described in detail herein.

Referring to fig. 3, in a preferred embodiment, the first purge chamber 200 has a first end surface 206 and a second end surface 208 opposite to each other, the first end surface 206 has at least one first air inlet channel 207 thereon, and the first air inlet channel 207 is used for connecting with an air source; a first gas collecting funnel 209 is arranged on the second end surface 208, a wide opening of the first gas collecting funnel 209 is communicated with the first blowing-out cavity 200, and a narrow opening of the first gas collecting funnel 209 is used for being connected with a waste gas collecting device. During operation, the first air inlet channel 207 is always blown out, so that an air flow flowing from the first end surface 206 to the first air collecting funnel 209 is formed in the first blow-off chamber 200, and after the pollutants on the part 204 are blown off from the surface of the part 204, the pollutants are brought into the first air collecting funnel 209 and then enter the exhaust gas collecting device. If the first air inlet channel 207 and the first air collecting funnel 209 are not provided, when the contaminants on the component 204 are blown off the surface of the component 204, the contaminants will be scattered in the cavity of the first cleaning chamber 200, which may be re-attached to the current component 204 or to a subsequent component 204, thereby causing the cleaning effect to be unsatisfactory. After the air inlet channel 207 and the first air collecting funnel 209 are arranged, pollutants scattered in the air are collected in time by utilizing the cooperation of the air flow and the first air collecting funnel 209, the cleanness degree of the air in the first blowing cavity 200 is always kept, and the blowing effect of the part 204 is further improved. It is to be understood that the selection and arrangement of the air supply, air line conduits and pneumatic components associated with the first air intake channel 207 may be understood and configured by one skilled in the art in accordance with common general knowledge in the art and will not be described in detail herein. The exhaust gas collecting device is a negative pressure device that can simply collect the exhaust gas or filter the exhaust gas, store the pollutant particles, and discharge the filtered air, and the specific embodiment thereof will be understood and configured by those skilled in the art according to the common general knowledge in the art, and will not be described in detail herein.

Referring to fig. 4, in an embodiment, a turnover mechanism 301, a guide rail mechanism 302 and a second air knife assembly 303 are disposed in the second blowing chamber 300, a turnover part of the turnover mechanism 301 is provided with a second clamp 304, and the second clamp 304 is used for clamping a material tray 700; the extending direction of the guide rail mechanism 302 is parallel to the turning axis of the turning mechanism 301, the second air knife assembly 303 is directly connected with the slider 305 of the guide rail mechanism 302 or connected with the slider 305 through the second rotating mechanism 306, and the air outlet of the second air knife assembly 303 faces the turning part of the turning mechanism 301.

It should be understood that "the extending direction of the rail mechanism 302 is parallel to the tilting axis of the tilting mechanism 301", the extending direction of the rail mechanism 302 and the tilting axis of the tilting mechanism 301 form an angle of 0 to 5 °, and other parts of the present specification should be understood in this way. Meanwhile, "the air outlet of the second air knife assembly 303 faces the turning part of the turnover mechanism 301," which should be understood to mean that the air outlet of the second air knife assembly 303 faces the turning part of the turnover mechanism 301 in an air blowing state, in an embodiment, the second air knife assembly 303 is directly connected to the slider 305 of the guide rail mechanism 302, in this embodiment, the air outlet of the second air knife assembly 303 always faces the turning part of the turnover mechanism 301 due to the limitation of the degree of freedom; in the embodiment shown in fig. 4, the second wind knife assembly 303 is connected to the sliding block 305 through the second rotating mechanism 306, so that the position of the second wind knife assembly 303 has a certain degree of freedom, and in the blowing state, the air outlet of the second wind knife assembly 303 faces the turning part of the turning mechanism 301; in a non-blowing state (including the material tray 700 turning process, at this time, the whole second blowing chamber 300 can be regarded as being in a working state, but the second air knife assembly 303 should be regarded as being in a non-blowing state), the air outlet of the second air knife assembly 303 is not toward the turning part of the turning mechanism 301, but is tightly attached to the guide rail mechanism 302 under the action of the second rotating mechanism 306, so that the advantage of the arrangement is that more space is provided for the turning of the material tray 700, and the whole size of the second blowing chamber 300 is reduced. Further, when the second air knife assembly 303 is in an air blowing state, the air outlet of the second air knife assembly 303 and one side of the material tray 700 contacting the second clamp 304 form an angle of 20 to 30 degrees, if the angle is too large, the length of the air outlet cannot be effectively utilized, and a longer second air knife assembly 303 is required to be provided to cover the whole material tray 700, so that the manufacturing cost is increased; the angle cannot be too small, and if the angle is too small, the contact time of the groove in the material tray 700 parallel to the side contacting the second clamp 304 is too short, and the blowing-off effect is not good.

Based on the above structure, the work flow of the second blow-down chamber 300 is as follows:

1) the second carrying mechanism 500 carries the material tray into the second blow-off chamber 300, and the second clamp 304 clamps the material tray 700;

2) the second air knife assembly 303 is driven by the second rotating mechanism 306 to rotate, and an air outlet of the second air knife assembly is in a certain angle with the material tray 700 in contact with the second clamp 304;

3) the second air knife assembly 303 starts to spray high-pressure clean air, and the guide rail mechanism 302 starts to operate at the same time, so that the second air knife assembly 303 is driven to sweep the bottom surface of the whole material tray 700. Subsequently, the slider 305 moves backward to the home position, and drives the second air knife assembly 303 to sweep the bottom surface of the material tray 700 again from the other side.

The step 3) can be repeated for a plurality of times according to actual conditions.

4) The second air knife assembly 303 is driven by the second rotating mechanism 306 to rotate and cling to the guide rail mechanism 302.

5) The turnover mechanism 303 rotates 180 degrees, so that the material tray 700 is turned over;

6) the second air knife assembly 303 is driven by the second rotating mechanism 306 to rotate, and the air outlet of the second air knife assembly is at a certain angle with the side of the material tray 700 contacting the second clamp 304;

7) the second air knife assembly 303 starts to spray high-pressure clean air, and the guide rail mechanism 302 starts to operate at the same time, so that the second air knife assembly 303 is driven to sweep the object placing surface of the whole material tray 700. Subsequently, the sliding block 305 moves reversely to return to the original position, and drives the second air knife assembly 303 to sweep the object placing surface of the material tray 700 from the other side again;

step 7) can be repeated for a plurality of times according to actual conditions.

8) The turnover mechanism 303 rotates 180 degrees, so that the material tray 700 is turned over again; the rotation direction is opposite to the direction in the step 5), and the configuration has the advantages that a wire or an air path can be arranged on the overturning part of the overturning mechanism 303, and the wire or the air path cannot be wound and damaged because the overturning part is continuously overturned in the same direction;

at this time, the blowing process may be ended, or step 9) may be added, the second carrying mechanism 500 picks up the material tray 700, the material tray 700 is rotated 180 degrees along the plane of the object placing surface, and then the steps 1) to 8) are repeated again

Step 9) can also be repeated for a plurality of times according to the actual situation;

finally, step 10) is performed, the second carrying mechanism 500 carries the material tray 700 which has been completely blown to the discharge port 102.

Through the steps, the object placing surface (directly contacted with the part 204) and the bottom surface (contacted with the part 204 positioned below when the object trays are stacked) of the material tray 700 can be completely blown, and the purpose of preventing secondary pollution is achieved.
