Description

Technical Field

[0001] This application relates to the field of detection technology, and in particular to a detection device. Background Technology

[0002] With the development of technology, in order to achieve specific and complex functions, the precision requirements for the components of various devices and equipment are becoming increasingly stringent. Therefore, it is now common practice to conduct defect detection and dimensional measurement on products before they leave the factory to eliminate defective products.

[0003] Traditional testing devices are usually equipped with a blowing module, which blows away dust and debris from the product surface to improve testing accuracy.

[0004] However, in traditional detection devices, dust and debris blown up by the air blowing module can still fall back onto the product surface, indicating insufficient dust removal. Summary of the Invention

[0005] Therefore, it is necessary to provide a testing device to address the problem of insufficient dust removal before product testing.

[0006] This application provides a detection device, which includes a base, a support, a dust removal structure, a detection module, and a transfer assembly. The support is mounted on the base. The dust removal structure has a material passage for workpieces to pass through. The dust removal structure also has a blowing air duct and a suction air duct that are respectively connected to the material passage. The blowing air duct is used to connect to a positive pressure generator to provide positive pressure airflow into the material passage. The suction air duct is used to connect to a negative pressure generator to form negative pressure suction airflow into the material passage. The detection module is used to detect the workpieces located within the detection range. The transfer assembly is movably mounted on the base along the material conveying direction. The transfer assembly includes a fixture for picking up the workpieces. Along the material conveying direction, the dust removal structure and the detection module are respectively located on opposite sides of the support, and the material passage extends along the material conveying direction.

[0007] In one embodiment, along the material conveying direction, the connecting portion of the blowing duct and the material passage is spaced apart from the connecting portion of the dust suction duct and the material passage; and the connecting portion of the dust suction duct and the material passage is closer to the side where the detection module is located relative to the connecting portion of the blowing duct and the material passage.

[0008] In one embodiment, the dust removal structure includes a substrate, a first clamping plate, and a second clamping plate. The first clamping plate is connected to the substrate and clamped together to form the blowing air duct, and the second clamping plate is connected to the substrate and clamped together to form the dust suction air duct. Along the material conveying direction, the first clamping plate and the second clamping plate are respectively attached to opposite sides of the substrate, and the second clamping plate is closer to the side where the detection module is located relative to the first clamping plate.

[0009] In one embodiment, the blowing duct includes an air outlet duct recessed in the wall of the material passage, the substrate includes a first wall portion that fits against the first clamping plate, the first wall portion includes a guide wall, the guide wall being a part of the structure that clamps to form the air outlet duct; the side of the guide wall near the material passage is relatively far from the side of the material passage, and deflects along the material conveying direction toward the location of the dust suction duct, so that the air outlet duct is deflected toward the side where the dust suction duct is located.

[0010] In one embodiment, the dust extraction duct includes an air inlet duct recessed in the wall of the material passage; of the two wall portions forming the air inlet duct, the side closer to the material passage is opened relative to the side farther away from the material passage, so that the air inlet duct is funnel-shaped.

[0011] In one embodiment, the purging duct includes a first main duct and a first connecting channel. The first main duct extends in an arch shape along the circumferential direction of the material passage and is arranged on the outer periphery of the material passage. The first main duct is used to communicate with a positive pressure generator. A plurality of first connecting channels are arranged at intervals and side by side in the circumferential direction of the material passage. The first connecting channels are located on the outer periphery of the material passage. The first connecting channels are distributed on the inner periphery of the first main duct. The flow area of ​​the first connecting channels is smaller than the flow area of ​​the first main duct. One end of the first connecting channel is connected to the first main duct, and the other end is connected to the material passage.

[0012] In one embodiment, the first clamping plate includes a purge wall that adheres to the substrate. The purge wall is recessed and has a first main groove and a first connecting groove. The first main groove extends in an arch shape along the circumferential direction of the material passage and is arranged on the outer periphery of the material passage. A plurality of first connecting grooves are arranged at intervals and side by side along the circumferential direction of the material passage. The first connecting grooves are located on the outer periphery of the material passage and are distributed on the inner periphery of the first main groove. The first main groove is closed by the substrate to form the first main passage, and the first connecting groove is closed by the substrate to form the first connecting channel. The recessed depth of the first main groove is greater than that of the first connecting groove, so that the flow area of ​​the first main passage is greater than that of the first connecting groove.

[0013] In one embodiment, the dust extraction duct includes a second main duct and a second connecting duct. The second main duct extends in an arch shape along the circumferential direction of the material passage and is arranged on the outer periphery of the material passage. The second main duct is used to communicate with a negative pressure generator. A plurality of second connecting ducts are arranged at intervals and side by side in the circumferential direction of the material passage. The second connecting ducts are located on the outer periphery of the material passage. The second connecting ducts are distributed on the inner periphery of the second main duct. The flow area of ​​the second connecting duct is smaller than that of the second main duct and larger than that of the first connecting duct. One end of the second connecting duct is connected to the second main duct, and the other end is connected to the material passage.

[0014] In one embodiment, the first clamping plate has a first bridge hole, the substrate has a second bridge hole, and the second clamping plate has a third bridge hole. The first bridge hole, the second bridge hole, and the third bridge hole have the same shape and size. Along the material conveying direction, the first bridge hole, the second bridge hole, and the third bridge hole are connected in sequence to form the material passage.

[0015] In one embodiment, along the material conveying direction, the material passage has an inlet and an outlet at both ends, and a clearance opening is provided on one side of the material passage in the circumferential direction. The clearance opening extends from the inlet to the outlet along the material conveying direction. The clearance opening allows the fixture carrying the workpiece to pass through. When the fixture is in the clearance opening, the material passage is partially closed by the fixture.

[0016] In one embodiment, the side wall of the material passage opposite to the clearance opening is configured to be concave arc-shaped.

[0017] In one embodiment, there are multiple dust removal structures, which are spaced apart on the support along a reference direction that intersects with the material conveying direction. The transfer assembly is provided with multiple fixtures, which are spaced apart along the reference direction. Each fixture corresponds to one of the multiple dust removal structures to transport multiple workpieces into multiple material passages.

[0018] In the aforementioned testing device, the dust removal structure has a material passage for the workpiece to pass through. The dust removal structure is equipped with a blowing duct and a suction duct connected to the material passage. On one hand, the suction duct works in conjunction with the blowing duct to draw in and recover dust that has been blown off the workpiece by the positive pressure airflow, reducing the likelihood of dust and debris being re-adsorbed onto the workpiece and making dust removal more thorough. On the other hand, both the blowing duct and the suction duct are connected to the material passage. The workpiece undergoes dust removal within the relatively enclosed material passage. The limited space within the material passage not only reduces the likelihood of dust leakage but also improves the thoroughness of blowing and suction, making dust removal more complete. Furthermore, the dust removal structure and the testing module are positioned on opposite sides of the support along the material conveying direction. The material passage extends along the material conveying direction, and the transfer assembly can transport the workpiece along the conveying direction. Therefore, under the transport of the transfer assembly, the workpiece can pass through the material passage of the dust removal structure and the testing module, and be tested immediately after dust removal, improving the accuracy of the test. Meanwhile, the transfer component can simultaneously perform dust removal and detection by moving along the conveying direction, thus improving the overall processing efficiency.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] Please see Figure 1 , Figure 1A side view of a detection device provided in an embodiment of this application is shown. The detection device 10 provided in an embodiment of this application includes a base (not shown, the same below), a support 11, a detection module 12, a transfer assembly 13, and a dust removal structure 14. The support 11, detection module 12, transfer assembly 13, and dust removal structure 14 are all disposed on the base. The detection module 12 is used to detect workpieces located within the detection range. The transfer assembly 13 includes a fixture 13a for picking up workpieces, and the transfer assembly 13 is movably disposed on the base along the conveying direction S. The support 11 is mounted on the base, and the detection module 12 and dust removal structure 14 are both disposed on the support 11, such that the detection module 12 and dust removal structure 14 have a higher position relative to the transfer assembly 13 and the workpiece picked up by the transfer assembly 13, facilitating detection by the detection module 12 and dust removal by the dust removal structure 14.

[0036] Furthermore, along the conveying direction S, the dust removal structure 14 and the detection module 12 are respectively located on opposite sides of the support 11. Therefore, when the transfer assembly 13 moves along the conveying direction S, it can carry the workpiece to the detection range of the detection module 12 for detection; and when the transfer assembly 13 moves along the conveying direction S, it can carry the workpiece to the dust removal structure 14 for dust removal. The dust removal structure 14 can remove dust from the workpiece, and after dust removal, the workpiece is detected by the detection module 12, improving the accuracy of the detection.

[0037] Please see Figure 1 and Figure 2 In one embodiment, the dust removal structure 14 has a material passage 400 for the workpiece to pass through. The material passage 400 extends along the conveying direction S, so the workpiece moves approximately along the conveying direction S within the material passage 400. The dust removal structure 14 also includes a blowing duct 101 and a suction duct 201, which are respectively connected to the material passage 400. The blowing duct 101 is also connected to a positive pressure generator to provide positive pressure airflow into the material passage 400, thereby blowing away dust and debris from the workpiece. The suction duct 201 is also connected to a negative pressure generator to create a negative pressure suction airflow within the material passage 400. This suction airflow recovers dust and debris separated from the workpiece, reducing the likelihood of dust and debris falling back onto the workpiece and making dust removal more thorough.

[0038] In the aforementioned testing device 10, the dust removal structure 14 has a material passage 400 through which the workpiece passes. The dust removal structure 14 is provided with a blowing air duct 101 and a suction air duct 201 connected to the material passage 400. On one hand, the suction air duct 201 works in conjunction with the blowing air duct 101 to suck up and recover the dust that has been blown off the workpiece by the positive pressure airflow, reducing the probability of dust and debris being re-adsorbed onto the workpiece and making dust removal more thorough. On the other hand, both the blowing air duct 101 and the suction air duct 201 are connected to the material passage 400. The workpiece is dusted within the relatively enclosed material passage 400. Due to the limited space within the material passage 400, not only is the probability of dust leakage reduced, but the thoroughness of blowing and suction is also improved, making dust removal more complete.

[0039] Furthermore, the dust removal structure 14 and the detection module 12 are arranged on opposite sides of the support 11 along the conveying direction S. The material passage 400 extends along the conveying direction S, and the transfer assembly 13 can transport the workpiece along the conveying direction. Therefore, under the transport of the transfer assembly 13, the workpiece can pass through the material passage 400 of the dust removal structure 14 and the detection module 12, and be detected immediately after dust removal, thus improving the accuracy of detection. At the same time, the transfer assembly 13 can complete the dust removal and detection steps simultaneously by moving along the conveying direction, simplifying the movement of the transfer assembly 13, making it easier to control, and improving the overall processing efficiency.

[0040] Please continue reading. Figure 1 and Figure 2 In one embodiment, along the material conveying direction S, the connecting portion of the blowing duct 101 and the material passage 400 (i.e., the inlet duct 202 mentioned below) is spaced apart from the connecting portion of the dust extraction duct 201 and the material passage 400 (i.e., the outlet duct 102 mentioned below). Furthermore, the connecting portion of the dust extraction duct 201 and the material passage 400 is closer to the side where the detection module 12 is located compared to the connecting portion of the blowing duct 101 and the material passage 400. Therefore, during the movement of the workpiece within the material passage 400, it can pass through the areas where the blowing duct 101 and the dust extraction duct 201 are located sequentially, allowing the dust separation process and the dust recovery process to proceed step-by-step, thus improving the thoroughness of dust removal.

[0041] Please see Figures 2 to 4 In one embodiment, the dust removal structure 14 includes a first clamping plate 100, a second clamping plate 200, and a substrate 300. The first clamping plate 100 is connected to and clamped with the substrate 300 to form a blowing air duct 101. The second clamping plate 200 is connected to and clamped with the substrate 300 to form a suction air duct 201. The blowing air duct 101 and the suction air duct 201 are formed by clamping the first clamping plate 100, the substrate 300, and the second clamping plate 201, making the dust removal structure 14 have a simpler structural distribution and composition, which facilitates its flexible arrangement in various required locations. For example, it can be arranged on the side of the bracket 11 opposite to the detection module 12, as described above.

[0042] Furthermore, along the material conveying direction S, the first clamping plate 100 and the second clamping plate 200 are respectively attached to opposite sides of the substrate 300, with the second clamping plate 200 being closer to the side where the detection module 12 is located relative to the first clamping plate 100. This results in the dust suction duct 201 formed by the clamping of the second clamping plate 200 and the substrate 300 being closer to the side where the detection module 12 is located, while the blowing duct 101 formed by the clamping of the first clamping plate 100 and the substrate 300 is farther away from the side where the detection module 12 is located. With this configuration, the transfer assembly 13 can drive the workpiece along the extension direction of the material passage 400 (i.e., the aforementioned material conveying direction S) through the blowing duct 101, the dust suction duct 201, and the detection module 12, ensuring that the workpiece is thoroughly dust-removed before detection, thus improving detection accuracy.

[0043] Of course, in another embodiment, the first clamping plate 100 and the second clamping plate 200 can also be attached to the same side of the substrate 300. For example, along the conveying direction, the first clamping plate 100 and the second clamping plate 200 are attached to the same side of the substrate 300 one after the other, so that the blowing air duct 101 and the dust suction air duct 201 formed by clamping can be distributed sequentially in the conveying direction S. For ease of understanding and explanation, each embodiment is described with the first clamping plate 100 and the second clamping plate 200 located on opposite sides of the substrate 300 as an example. The same principle applies when the first clamping plate 100 and the second clamping plate 200 have other distribution positions with the substrate 300, unless there is a contradiction, so each embodiment will not be described in detail.

[0044] Please see Figure 2 and Figure 4 In one embodiment, the dust removal structure 14 further includes a plurality of air connectors 500, some of which are located on the side of the first clamping plate 100 away from the base plate 300 and are used to communicate with a positive pressure generator. Other portions of the plurality of air connectors 500 are located on the side of the second clamping plate 200 away from the base plate 300 and are used to communicate with a negative pressure generator.

[0045] In one embodiment, since the blowing duct 101 is formed by clamping the first clamping plate 100 and the substrate 300, and the suction duct 201 is formed by clamping the second clamping plate 200 and the substrate 300, at least one of the first clamping plate 100 and the second clamping plate 200 can be detachably connected to the substrate 300 so as to disassemble and open the blowing duct 101 and / or the suction duct 201 for cleaning, unblocking, etc.

[0046] Please see Figure 3 and Figure 4In one embodiment, the material passage 400 has an inlet 410 and an outlet 420 at both ends along the material conveying direction S. Furthermore, a clearance opening 430 is provided on one side of the material passage 400 in the circumferential direction, extending from the inlet 410 to the outlet 420 along the material conveying direction S. The clearance opening 430 is used to allow the fixture 13a carrying the workpiece to pass through. In this embodiment, the clearance opening 430 is configured to allow the fixture 13a to pass through, facilitating the transfer assembly 13 to maintain the movement of the carried workpiece. The material passage 400 is partially closed by the fixture 13a when the fixture 13a is within the clearance opening 430. That is, when the fixture 13a carrying the workpiece moves into the clearance opening 430, it can block the clearance opening 430, making the material passage 400 form a relatively closed cavity, which is referred to as the dust removal cavity 401. Since the workpiece is dusted in the relatively enclosed dust removal chamber 401, the probability of dust being lifted and leaked out by the positive pressure airflow is reduced. On the other hand, since the dust removal chamber 401 is relatively enclosed, the movement of dust is restricted, which makes it easier for the dust suction duct 201 to fully recover the dust, reduce the probability of dust falling back to the workpiece, and make the dust removal more thorough.

[0047] Furthermore, the inlet 410 is located on the first clamping plate 100, and the outlet 420 is located on the second clamping plate 200. Simultaneously, since the blowing duct 101 is formed by the clamping of the first clamping plate 100 and the substrate 300, the blowing duct 101 is located on the side closer to the inlet 410. Correspondingly, since the dust suction duct 201 is formed by the clamping of the second clamping plate 200 and the substrate 300, the dust suction duct 201 is located on the side closer to the outlet 420. Therefore, when the workpiece enters the material passage 400 through the inlet 410, the inlet 410 is blocked by the workpiece itself, and the bottom clearance opening 430 is blocked by the fixture 13a. This causes the dust, stirred up by the positive pressure airflow, to tend to move towards the outlet 420, thus facilitating the thorough dust collection by the dust suction duct 201 located on the side where the outlet 420 is located.

[0048] Please see Figure 3 In one embodiment, the maximum width of the clearance opening 430 is L1, and the maximum width of the fixture 13a is L2, where 1.05L2≤L1≤1.80L2, so that the fixture 13a can fully block the clearance opening 430 while ensuring the smooth passage of the fixture 13a, thus making the dust removal chamber 401 relatively closed. Further, the ratio of the maximum width L1 of the clearance opening 430 to the maximum width L2 of the fixture 13a can be: 1.05, 1.10, 1.12, 1.14, 1.16, 1.18, 1.20, 1.25, 1.30, 1.35, 1.40, 1.45, 1.50, 1.55, 1.60, 1.65, 1.70, 1.75, and 1.80, etc., and can be designed according to actual needs.

[0049] Please continue reading. Figure 3In one embodiment, the side of the material passage 400 wall opposite to the relief opening 430 is constructed as a concave arc shape to facilitate the passage of workpieces of various shapes while reducing the internal space of the material passage 400 (i.e., the dust collection chamber 401). Simultaneously, compared to a wall with sharp corners or edges, constructing the wall as an arc shape reduces the probability of dust accumulation and facilitates thorough dust recovery. It should be noted that the concave arc shape of the wall refers to its concave arc shape in a cross-section perpendicular to the material conveying direction S. The side of the material passage 400 wall opposite to the relief opening 430 may be partially cylindrical.

[0050] Please see Figure 4 and Figure 5 Combined Figure 2 In one embodiment, the first clamping plate 100 has a first bridge hole 110, the substrate 300 has a second bridge hole 310, and the second clamping plate 200 has a third bridge hole 210. The first bridge hole 110, the second bridge hole 310, and the third bridge hole 210 have the same shape and size. Along the material conveying direction S, the first bridge hole 110, the second bridge hole 310, and the third bridge hole 210 are connected in sequence to form a material passage 400. Since the first bridge hole 110, the second bridge hole 310, and the third bridge hole 210 forming the material passage 400 have the same shape and size, the connection between the first clamping plate 100 and the substrate 300, and the connection between the substrate 300 and the second clamping plate 200, are smoother. This makes the inner wall of the material passage 400 smooth and regular, reducing the probability of sharp edges appearing in the material passage 400 and blocking or accumulating dust, thus making dust removal more thorough.

[0051] Please see Figure 5 Furthermore, the aforementioned inlet 410 may be located on the side of the first archway 110 away from the substrate 300, and the aforementioned outlet 420 may be located on the side of the third archway 210 away from the substrate 300.

[0052] Please see Figure 4 and Figure 5 In one embodiment, the substrate 300 includes a first wall portion 320 and a second wall portion 330. Along the material conveying direction S, the first wall portion 320 and the second wall portion 330 are disposed opposite to each other. A first clamping plate 100 is connected to the first wall portion 320 and clamps with the first wall portion 320 to form a blowing air duct 101 as described in various embodiments. A second clamping plate 200 is connected to the second wall portion 330 and clamps with the second wall portion 330 to form a suction air duct 201 as described in various embodiments.

[0053] The first wall portion 320 and the second wall portion 330 are parallel to each other and both perpendicular to the material conveying direction S. Therefore, the distribution area of ​​the blowing air duct 101 formed by the first clamping plate 100 and the first wall portion 320 is approximately perpendicular to the material conveying direction S. Similarly, the distribution area of ​​the dust suction air duct 201 formed by the second clamping plate 200 and the second wall portion 330 is also approximately perpendicular to the material conveying direction S. Thus, after the workpiece enters the material passage 400 along the material conveying direction S, it is first swept away by positive pressure airflow to remove dust, and then passes through the area where the dust suction air duct 201 is located. This arrangement ensures that the dust stirred up by the positive pressure airflow can be fully recovered by the dust suction air duct 201.

[0054] Furthermore, the blowing duct 101 can be formed by recesses in the surfaces of the first clamping plate 100 and / or the first wall portion 320. Similarly, the suction duct 201 can be formed by recesses in the surfaces of the second clamping plate 200 and / or the second wall portion 330. For ease of explanation, each embodiment is described with the example that the recesses forming the blowing duct 101 are distributed on the first clamping plate 100 and the recesses forming the suction duct 201 are distributed on the second clamping plate 200, that is, in this case, the first wall portion 320 and the second wall portion 330 are relatively flat.

[0055] Please see Figure 6 Combined Figure 3 In one embodiment, the purge duct 101 includes a first main duct 103 and a first connecting channel 104, which are interconnected. The first main duct 103 is used to connect to a positive pressure generator, that is, the first main duct 103 is used to receive a positive pressure airflow. The first main duct 103 extends in an arch shape along the circumferential direction C of the material passage 400 on the outer periphery of the material passage 400. A plurality of first connecting channels 104 are arranged at intervals and side by side in the circumferential direction C of the material passage 400. The first connecting channels 104 are located on the outer periphery of the material passage 400 and are distributed on the inner periphery of the first main duct 103. That is, in the direction perpendicular to the circumferential direction C of the material passage 400, the first main duct 103, the first connecting channels 104, and the material passage 400 are distributed sequentially from the outside to the inside. One end of the first connecting channel 104 is connected to the first main duct 103, and the other end is connected to the material passage 400. The first main channel 103 is configured to extend in an arch shape along the aforementioned circumferential direction, so that the first main channel 103 can provide positive pressure airflow to the first connecting channel 104 located at various locations in the circumferential direction. This allows the positive pressure airflow to simultaneously provide positive pressure airflow to the workpiece located in the material passage 400 from multiple areas in the circumferential direction, so as to fully blow away any dust and debris that may exist on the surface of the workpiece.

[0056] Furthermore, the flow area of ​​the first connecting channel 104 is smaller than that of the first main channel 103, enabling the first connecting channel 104 to accelerate the positive pressure airflow from the first main channel 103, thereby improving the dust removal effect. It is easy to understand that, according to the fluid dynamics formula: V=Q / A; where V is the fluid velocity, Q is the fluid volumetric flow rate, and A is the fluid flow area, when the flow rate is constant, a smaller flow area results in a higher flow velocity, and a higher flow velocity leads to a better dust removal effect.

[0057] Please see Figure 6 and Figure 7 In one embodiment, the purge duct 101 further includes an outlet duct 102, which is recessed into the wall of the material passage 400, making the wall of the material passage 400 smoother and reducing the probability of sharp edges and corners, thus reducing dust accumulation. Furthermore, since the outlet duct 102 is recessed into the wall of the material passage 400, it is a part of the purge duct 101 directly connected to the material passage 400. In other words, the outlet duct 102 is connected to the end of the first connecting channel 104 opposite to the first main channel 103; that is, the first main channel 103, the first connecting channel 104, and the outlet duct 102 are sequentially connected to provide positive pressure airflow into the material passage 400.

[0058] Furthermore, the air outlet duct 102 can be deflected or tilted to the side where the dust suction duct 201 is located, so as to drive and guide the dust raised by the positive pressure airflow to the side where the dust suction duct 201 is located, so that the dust suction duct 201 can fully recover the dust.

[0059] Furthermore, the air outlet duct 102 can be arranged in an arch shape along the circumferential direction C of the material passage 400 on the wall of the material passage 400 to improve the uniformity of dust removal.

[0060] Please see Figure 6 In one embodiment, the first main channel 103 may be arranged in an arch shape along the circumferential direction C1 of the first archway 110 on the outer periphery of the material passage 400, and a plurality of first connecting channels 104 may be arranged at intervals and side by side on the circumferential direction C1 of the first archway 110.

[0061] like Figure 7 Combined Figure 4 In one embodiment, the first wall portion 320 includes a guide wall 321, which is a part of the structure that is clamped to form the air outlet duct 102. The side of the guide wall 321 closest to the material passage 400 is relatively far from the material passage 400 and deflects along the material conveying direction S toward the location of the dust collection duct 201, so that the air outlet duct 102 is deflected toward the side where the dust collection duct 201 is located. Then, the dust that is raised will move toward the side where the dust collection duct 201 is located along with the positive pressure airflow, which makes it easier for the dust collection duct 201 to fully recover the dust.

[0062] Furthermore, the guide wall 321 can deflect in a planar manner or in a curved manner.

[0063] Please see Figure 8 Combined Figure 3 In one embodiment, the suction duct 201 includes a second main duct 203 and a second connecting channel 204, which are interconnected. The second main duct 203 is used to connect to a negative pressure generator, that is, the second main duct 203 is used to receive negative pressure suction airflow. The second main duct 203 extends in an arch shape along the circumferential direction C of the material passage 400 on the outer periphery of the material passage 400. A plurality of second connecting channels 204 are arranged at intervals and side by side in the circumferential direction C of the material passage 400. The second connecting channels 204 are located on the outer periphery of the material passage 400 and are distributed on the inner periphery of the second main duct 203. That is, in the direction perpendicular to the circumferential direction C of the material passage 400, the second main duct 203, the second connecting channels 204, and the material passage 400 are distributed sequentially from the outside to the inside. One end of the second connecting channel 204 is connected to the second main duct 203, and the other end is connected to the material passage 400. The second main channel 203 is configured to extend along the aforementioned circumferential direction C, so that the second main channel 203 can form a negative pressure suction airflow in the material passage 400 through the second connecting channels 204 located at various points in the circumferential direction C, making the negative pressure dust collection more uniform, so as to fully recover the dust and debris in the material passage 400.

[0064] Furthermore, the flow area of ​​the second connecting channel 204 is smaller than that of the second main channel 203 to improve the dust collection efficiency of the suction duct 201. The flow area of ​​the second connecting channel 204 is larger than that of the first connecting channel 104, which facilitates dust collection in the second connecting channel 204 with a relatively large flow rate, thereby improving the dust collection effect.

[0065] Please see Figure 8 In one embodiment, the second main channel 203 may be arranged in an arch shape along the circumferential direction C2 of the third tunnel 210 on the outer periphery of the material passage 400, and a plurality of second connecting channels 204 may be arranged at intervals and side by side on the circumferential direction C2 of the third tunnel 210.

[0066] Please see Figure 7 and Figure 8In one embodiment, the suction duct 201 includes an air inlet duct 202, which is recessed into the wall of the material passage 400, making the wall of the material passage 400 smoother and reducing the likelihood of sharp edges and corners, thus reducing dust accumulation. Furthermore, since the air inlet duct 202 is recessed into the wall of the material passage 400, it is a part of the suction duct 201 directly connected to the material passage 400. In other words, the air inlet duct 202 connects to the side of the second connecting channel 204 opposite to the second main channel 203; that is, the second main channel 203, the second connecting channel 204, and the air inlet duct 202 are sequentially connected to form a negative pressure suction airflow within the material passage 400.

[0067] Furthermore, in the two wall portions forming the air inlet duct 202, the side closer to the material passage 400 is opened relative to the side farther away from the material passage 400, so that the air inlet duct 202 is funnel-shaped, so as to guide the airflow mixed with dust in the material passage 400 into the dust suction duct 201.

[0068] Furthermore, the air inlet duct 202 can be arranged in an arch shape along the circumferential direction C of the material passage 400 to uniformly draw dust from all circumferential locations.

[0069] Regarding the purge duct 101, in one embodiment, the purge duct 101 may only include the first main duct 103, that is, the first main duct 103 directly provides positive pressure airflow into the material passage 400. Alternatively, in another embodiment, the purge duct 101 may include the first main duct 103 and the outlet duct 102, which are interconnected. The outlet duct 102 is used to guide the positive pressure airflow output by the first main duct 103 to deflect towards the side closer to the suction duct 201, facilitating dust collection in the suction duct 201. Or, in yet another embodiment, the purge duct 101 may only include the outlet duct 102, which is used to guide the positive pressure airflow provided by the positive pressure generator to deflect towards the side closer to the suction duct 201, facilitating dust collection in the suction duct 201.

[0070] Regarding the suction duct 201, similar to the blowing duct 101, in one embodiment, the suction duct 201 may only include the second main duct 203, that is, the second main duct 203 directly forms a negative pressure suction airflow within the material passage 400. Alternatively, in another embodiment, the blowing duct 101 may include the interconnected second main duct 203 and the inlet duct 202, the inlet duct 202 being used to guide the airflow mixed with dust within the material passage 400 into the suction duct 201, improving dust collection efficiency. Or, in yet another embodiment, the blowing duct 101 may only include the inlet duct 202, the inlet duct 202 being used to guide the airflow mixed with dust within the material passage 400 into the suction duct 201, improving dust collection efficiency. Further, the detection device 10 may also include a dust box (not shown, the same below), the dust box being connected between the suction duct 201 and the positive pressure generator, for storing the recovered dust and debris.

[0071] Please refer to it again. Figure 6 Combined Figure 3 In one embodiment, the first clamping plate 100 includes a purge wall 120 for attaching to the substrate 300. The purge wall 120 is recessed and has a first main groove 130 and a first connecting groove 140.

One end of each of the plurality of first connecting grooves 140 connects to the first main groove 130, and the other end connects to the material passage 400. The first main groove 130 is closed by the substrate 300 to form a first main channel 103, and the first connecting grooves 140 are closed by the substrate 300 to form a first connecting channel 104. The recess depth of the first main channel 130 is greater than that of the first connecting channel 140, so that the flow area of ​​the first main channel 103 is greater than that of the first connecting channel 140.

[0072] Please see Figure 6 and Figure 7 In one embodiment, the region of the purge wall 120 located on the inner periphery of the first main channel 103 is provided with a plurality of spaced-apart first abutments 150, which are used to abut against the first wall portion 320.

[0073] Furthermore, a mating wall 160 is provided in the area of ​​the purge wall 120 located on the inner periphery of the first connecting channel 104.

[0074] Please see Figure 6 In one embodiment, the wall of the first main groove 130 is provided with an air inlet 170, which is used to connect to the air connector 500.

[0075] Please see Figure 8 Combined Figure 3 In one embodiment, the second clamping plate 200 includes a dust collection wall 220 for attaching to the substrate 300. The dust collection wall 220 is recessed and has a second main groove 230 and a second connecting groove 240. The second main groove 230 extends in an arched shape along the circumferential direction C of the material passage 400 on the outer periphery of the material passage 400. A plurality of second connecting grooves 240 are arranged at intervals and side-by-side along the circumferential direction C of the material passage 400, located on the outer periphery of the material passage 400 and distributed on the inner periphery of the second main groove 230. One end of each of the plurality of second connecting grooves 240 connects to the second main groove 230, and the other end connects to the material passage 400. The second main groove 230 is closed by the substrate 300 to form a second main passage 203, and the second connecting grooves 240 are closed by the substrate 300 to form a second connecting channel 204. The recess depth of the second main channel 230 is greater than that of the second connecting channel 240, so that the flow area of ​​the formed second main channel 203 is greater than that of the second connecting channel 240.

[0076] Please see Figure 7 In one embodiment, the area of ​​the dust collection wall 220 located on the inner periphery of the second main channel 203 is provided with a plurality of spaced second abutments 250, which are used to abut against the second wall portion 330. Furthermore, the plurality of second abutments 250 are spaced apart along the circumferential direction C2 of the third bridge opening 210, and the gap between adjacent second abutments 250 is closed by the substrate 300 to form the second connecting channel 204 as described above.

[0077] Furthermore, the recess depth of the second connecting groove 240 can be configured to be greater than the recess depth of the first connecting groove 140, so that the flow area of ​​the second connecting channel 204 is greater than the flow area of ​​the first connecting channel 104. Please refer to [link / reference]. Figure 6 and Figure 8 Furthermore, the spacing between adjacent second abutment blocks 250 can be configured to be greater than the distance between adjacent first abutment blocks 150, so that the flow area of ​​the second connecting channel 204 is greater than the flow area of ​​the first connecting channel 104.

[0078] Please see Figure 7 and Figure 8 In one embodiment, the dust collection wall 220 has a first outward expansion wall 260 located on the inner peripheral side of the second connecting channel 204. Along the conveying direction S, the second wall portion 330 has a second outward expansion wall 331 located in the region opposite to the first outward expansion wall 260. The first outward expansion wall 260 and the second outward expansion wall 331 are sandwiched to form the air inlet duct 202 as described above, and their inner peripheral sides open away from each other relative to their outer peripheral sides, making the air inlet duct 202 funnel-shaped.

[0079] Please see Figure 8 In one embodiment, the second main groove 230 has an air outlet 270 on its groove wall, which is used to connect to the air connector 500.

[0080] Please see Figure 9 In one embodiment, the number of dust removal structures 14 is multiple, meaning the detection device 10 may include multiple dust removal structures 14. These multiple dust removal structures 14 are spaced apart along a reference direction K on the support 11, where the reference direction K intersects the material conveying direction S. The transfer assembly 13 is provided with multiple fixtures 13a, which are spaced apart along the reference direction K. Each fixture 13a corresponds one-to-one with a single dust removal structure 14, thereby transporting multiple workpieces into multiple material passages 400 for batch dust removal.

[0081] Furthermore, the number of detection modules 12 can also be multiple, with multiple detection modules 12 spaced apart along the reference direction K on the support 11, and corresponding one-to-one with multiple dust removal structures 14. Thus, after multiple workpieces have completed dust removal along the conveying direction S with the transfer assembly 13, they can further move along the conveying direction S with the transfer assembly 13 to the detection range of the detection module 12. After batch dust removal of the workpieces, further batch inspection of the workpieces is performed, improving processing efficiency.
