[0083] It should be noted that the auxiliary processing device 100 is used to cooperate with an external processing mechanism to process a workpiece, wherein the positioning hole 150a is used to adsorb the workpiece so that the external processing mechanism can position the workpiece, and after the external processing mechanism positions the workpiece, the gas guide hole 150b guides the preset gas to the workpiece. For example, the preset gas can be a protective gas, a high-temperature dry gas, etc.

[0084] See also Figures 2 to 4 In some embodiments, the base 110 includes a bracket 111, a support member 112 and a fixing member 113.

In this embodiment, the bracket 111 is a hollow structure.

[0085] See also Figure 4 and 5In some embodiments, the ventilator 120 includes a ventilator 121 and two sealing bodies 122. The ventilator 121 is arranged in the bracket 111 along the X-axis direction and inserted in the mounting groove 110a.

One end of the ventilator channel 121a is used to connect to an external suction source, and the other end of the ventilator channel 121a is used to connect to an external blowing source. The first opening 121b and the second opening 121c are both provided on the outer side of the ventilator 121 and are respectively connected to the ventilator channel 121a. The first opening 121b is connected to the suction hole 110b, and the second opening 121c is connected to the blowing hole 110c. The two sealing bodies 122 are both sleeved on the ventilator 121 and are interference fit with the side wall of the mounting groove 110a. The first opening 121b and the second opening 121c are both located between the two sealing bodies 122.

[0086] Therefore, the two ends of the ventilator 120 are respectively used to connect to the external suction source and blowing source, which simplifies the suction and blowing process and is beneficial to improving the ventilation efficiency.

[0087] See also Figure 3 In some embodiments, the support member 112 includes a support body 1121 and two position limiting bodies 1122. The support body 1121 is disposed on the bracket 111, the mounting groove 110a, the air suction hole 110b and the air blowing hole 110c are all provided on the support body 1121, the sliding member 130 is slidably disposed on the support body 1121 along the Y-axis direction, and the switching assembly 140 is disposed on the support body 1121. The two position limiting bodies 1122 are respectively connected to the support body 1121 and are arranged opposite to each other along the X-axis direction, and the fixing member 113 is connected to at least one of the support body 1121 and the two position limiting bodies 1122.

[0088] Therefore, the support body 1121 , the two limiting bodies 1122 and the fixing member 113 can be arranged to form a limiting space for the switching component 140 , which is beneficial to improving the stability of the movement of the switching component 140 .

[0089] In some embodiments, see Figure 2 The fixing member 113 includes a horizontal body 1131 and a vertical body 1132. The horizontal body 1131 is covered by two limiting bodies 1122, the switching assembly 140 is arranged through the horizontal body 1131 along the Z-axis direction, the vertical body 1132 is connected to the horizontal body 1131 and the supporting body 1121 respectively, and the sliding member 130 is arranged between the vertical body 1132 and the linkage member 150.

[0090] In other embodiments, the vertical body 1132 may be connected to only one of the limiting bodies 1122 , or to both limiting bodies 1122 , or to the supporting body 1121 and the two limiting bodies 1122 respectively.

[0091] See also Figure 2and Figure 5 In some embodiments, the switching assembly 140 includes a rotating member 141, a connecting shaft 142, and a handle 143. The rotating member 141 is rotatably disposed on the supporting body 1121, and is used to drive the sliding member 130 to move along the Y-axis direction. The connecting shaft 142 is penetrated through the horizontal body 1131 along the Z-axis direction, and one end of the connecting shaft 142 is connected to the rotating member 141. The handle 143 is connected to the other end of the connecting shaft 142, and is used to drive the rotating member 141 to rotate through the connecting shaft 142.

[0092] Therefore, by rotating the handle 143 , the rotating member 141 is placed in different states, thereby realizing the conversion of the sliding member 130 between the first position and the second position.

[0093] In some embodiments, the sliding member 130 is provided with a movable groove 130c, and the movable groove 130c penetrates the sliding member 130 along the Z-axis direction. The rotating member 141 is accommodated in the movable groove 130c and includes a rotating body 1411, a stopper 1412 and an elastic body 1413. The rotating body 1411 is rotatably arranged on the supporting body 1121, and the circumferential side of the rotating body 1411 has a first abutting surface 1411a and a second abutting surface 1411b. The stopper 1412 is arranged on the supporting body 1121 and is located between the rotating body 1411 and the elastic body 1413. The two ends of the elastic body 1413 are respectively abutted against the stopper 1412 and the side wall of the movable groove 130c. When the first supporting surface 1411a is supported against the side wall of the movable groove 130c, the sliding member 130 is in the first position or the second position, and pushes the elastic body 1413 to the stop body 1412. When the second supporting surface 1411b is supported against the side wall of the movable groove 130c, the elastic body 1413 pushes the sliding member 130 and makes the sliding member 130 in the second position or the first position.

[0094] Exemplarily, the stopper 1412 is inserted into the support body 1121 along the Z-axis direction, and the elastic body 1413 is a spring. In other embodiments, the rotating member 141 is also connected to the connecting rod structure of the sliding member 130 .

[0095] Therefore, the rotating member 141 is accommodated in the movable groove 130 c, which can reduce the occupied space of the auxiliary processing device 100 and is conducive to the miniaturization of the auxiliary processing device 100 .

[0096] See also Figure 2 and Figure 5 In some embodiments, at least one of the side wall of the movable groove 130c facing the elastic body 1413 and the side of the stopper 1412 facing the elastic body 1413 is provided with a receiving groove 141a, and part of the elastic body 1413 is received in the receiving groove 141a.

[0097] In this embodiment, the side wall of the movable groove 130c facing the elastic body 1413 and the side of the stopper 1412 facing the elastic body 1413 are both provided with the accommodating groove 141a. In other embodiments, the accommodating groove 141a may be provided only on the side wall of the movable groove 130c facing the elastic body 1413, or on the side of the stopper 1412 facing the elastic body 1413.

[0098] Therefore, the receiving groove 141 a can limit the elastic body 1413 in the radial direction of the elastic body 1413 , which is beneficial to the stability of the elastic force applied by the elastic body 1413 .

[0099] In some embodiments, the first abutting surface 1411 a is an arcuate surface, the second abutting surface 1411 b is a plane, and the distance between the first abutting surface 1411 a and the connecting shaft 142 is greater than the distance between the second abutting surface 1411 b and the connecting shaft 142 .

[0100] It should be noted that, in the present embodiment, the distance between the air intake opening 110d and the air passage 121a is smaller than the distance between the air blowing opening 110e and the air passage 121a; the opening of the air intake channel 130a toward the support body 1121 and the opening of the air blowing channel 130b toward the support body 1121 may be offset in the X-axis direction or may be flush; when the first abutting surface 1141a abuts against the side wall of the sliding member 130, the opening of the air intake channel 130a toward the support body 1121 corresponds to the air intake opening 110d, and the opening of the air blowing channel 130b toward the support body 1121 is offset from the air blowing opening 110e; when the second abutting surface 1141b abuts against the side wall of the sliding member 130, the opening of the air intake channel 130a toward the support body 1121 is offset from the air intake opening 110d, and the opening of the air blowing channel 130b toward the support body 1121 corresponds to the air blowing opening 110e.

[0101] In other embodiments, when the first abutting surface 1141a abuts against the side wall of the sliding member 130, the opening of the suction channel 130a toward the support body 1121 is offset from the suction opening 110d, and the opening of the blowing channel 130b toward the support body 1121 corresponds to the blowing opening 110e; when the second abutting surface 1141b abuts against the side wall of the sliding member 130, the opening of the suction channel 130a toward the support body 1121 corresponds to the suction opening 110d, and the opening of the blowing channel 130b toward the support body 1121 is offset from the blowing opening 110e.

[0102] See also Figure 3 and Figure 4In some embodiments, the suction hole 110b and the blowing hole 110c are both extended along the Y-axis direction, and the suction hole 110b and the blowing hole 110c are spaced apart along the X-axis direction, the suction opening 110d penetrates the side wall of the suction hole 110b along the Z-axis direction, and the blowing opening 110e penetrates the side wall of the blowing hole 110c along the Z-axis direction.

[0103] Therefore, the above configuration can simplify the processing of the base 110 and reduce the processing cost of the base 110 .

[0104] In the above-mentioned auxiliary processing device 100, the sliding member 130 can be switched between the first position and the second position under the drive of the switching component 140. When the sliding member 130 is in the first position, the suction channel 130a is connected to the suction opening 110d, and the sliding member 130 covers the blowing opening 110e. At this time, the external suction source can be connected through the ventilation member 120, so that the positioning hole 150a of the linkage member 150 adsorbs the workpiece to cooperate with the external mechanism to achieve the positioning of the workpiece. When the sliding member 130 is in the second position relative to the base 110, the blowing channel 130b is connected to the blowing opening 110e, and the sliding member 130 covers the suction opening 110d. At this time, the external blowing source can be connected through the ventilation member 120, so that the preset gas blown out by the blowing source passes through the blowing hole 110c, the blowing channel 130b, and the air guide hole 150b in sequence and blows to the workpiece that has been positioned by the external mechanism.

[0105] Therefore, the auxiliary processing device 100 can realize adsorption of the workpiece and blowing of the preset gas to the workpiece by changing the position of the sliding member 130 relative to the base 110, thereby simplifying the processing process of the workpiece and improving the processing efficiency of the workpiece. In addition, the auxiliary processing device 100 has a simple structure and low manufacturing cost, which reduces the processing cost of the workpiece.
