Description

Technical Field

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

[0002] As various products gradually develop towards higher precision and accuracy, the accuracy requirements for product testing are also increasing. In related technologies, independent positioning components are typically configured to achieve high-precision testing. A transport device transfers the workpiece to the positioning component for precise positioning, and after positioning, another transport device moves it to the testing station.

[0003] However, in the above-mentioned conveying and positioning method, the workpiece needs to be transferred multiple times between the conveying device, the positioning component, and another conveying device. This is not only inefficient, but also requires different conveying devices to transfer the workpiece to the positioning component, making the overall equipment structure complex. Utility Model Content

[0004] Therefore, it is necessary to provide a detection device and detection equipment to address the above problems.

[0005] This application provides a detection device, comprising a transfer assembly, a lifting assembly, and a detection module. The transfer assembly includes a pickup component and a transport component. The pickup component is disposed on the transport component, which includes a turntable and a transport driver. The transport driver is connected to the turntable to drive the turntable to rotate. Multiple pickup components are spaced apart on the turntable around its rotation axis. The transport component can drive each pickup component to move between a first station and a detection station. The lifting assembly includes a lifting driver and a reference platform. The lifting driver is connected to the reference platform to drive the reference platform to rise and fall. The reference stage includes a stage body, and a first positioning member and a second positioning member, both disposed on the stage body. The first positioning member and the second positioning member are arranged facing each other and spaced apart in a reference direction. The detection module is aligned with the pickup component at the detection station. The pickup component includes clamping members, and at least two clamping members are capable of moving towards and away from each other along the clamping direction. When the pickup component is at the first station, the clamping space between the clamping members overlaps with the space between the first positioning member and the second positioning member in the orthographic projection of the reference stage along the lifting direction of the reference stage. The clamping direction intersects with the reference direction.

[0006] In one embodiment, the first positioning member and / or the second positioning member are adjustablely positioned on the platform along the reference direction.

[0007] In one embodiment, the clamping member includes a connecting rod and contact portions, the connecting rod extending in a direction intersecting the clamping direction, and at least two contact portions spaced apart on the side of the connecting rod near the other clamping member.

[0008] In one embodiment, the contact portion has a rounded shape.

[0009] In one embodiment, the contact portion is a flexible body.

[0010] In one embodiment, the detection device further includes a sensing component and a cleaning component. The cleaning component has a first cleaning head. A portion of the structure of the sensing component and the first cleaning head are movably disposed along the lifting direction. The picking component can also be driven to move to a sensing station and a cleaning station. The sensing component is used to sense the position of the workpiece picked up by the picking component at the sensing station in the lifting direction. The cleaning component is aligned with the picking component at the cleaning station.

[0011] In one embodiment, the sensing component includes a first sensor movably disposed along the lifting direction, the first sensor being aligned with the picking component at the sensing station, and along the lifting direction, the first sensor being triggered when there is a preset distance between it and the top surface of the workpiece picked up by the picking component.

[0012] In one embodiment, the sensing component includes a second sensor and a movable member, a portion of the movable member being configured as an elastic body. Both the second sensor and the movable member are movably disposed along the lifting direction, and the movable member is movable relative to the second sensor. The movable member is used to move relative to the second sensor when it is abutted by the top surface of the workpiece, thereby triggering the second sensor.

[0013] In one embodiment, the cleaning assembly further includes a stand and a first drive module, the first drive module being disposed on the stand and connected to the first cleaning head to drive the first cleaning head to move along the lifting direction.

[0014] In one embodiment, the cleaning assembly further includes a second drive module connected to the stand, which drives the stand to move along a cleaning direction that intersects with the lifting direction.

[0015] In one embodiment, the cleaning assembly further includes a second cleaning head, which is disposed facing the first cleaning head; when the pickup component is in the cleaning station, the second cleaning head and the first cleaning head are respectively located on different sides of the pickup component.

[0016] In one embodiment, the portion of the clamping member that contacts the workpiece extends outward relative to the turntable.

[0017] In one embodiment, the plurality of detection modules correspond one-to-one with the pickup components at the plurality of detection stations, and the relative position of at least one of the detection modules and the pickup component at the corresponding detection station is different from the relative position of the other detection modules and the pickup components at the corresponding detection stations.

[0018] In one embodiment, the clamping direction is perpendicular to the reference direction.

[0019] This application also provides a testing device, which includes the testing apparatus described above.

[0020] In the aforementioned detection device, the transport component can drive each pickup component to move to the first station. At the first station, the space between the first positioning member and the second positioning member is used to place the workpiece. When the pickup component moves to the first station, the clamping space between the clamping members overlaps with the space between the first and second positioning members along the lifting direction of the reference platform and its orthographic projection on the reference platform, and the reference platform can move in the lifting direction. Thus, by operating the reference platform to move in the lifting direction, the first and second positioning members can be moved to the same position as the two clamping members in the lifting direction. At this time, the first positioning member, the second positioning member, and the two clamping members can position the workpiece. Specifically, at least two of the clamping members of the pickup component can move towards and away from each other along the clamping direction, and the first and second positioning members of the reference platform are arranged facing each other and spaced apart in the reference direction. Since the clamping direction intersects the reference direction, at least two clamping members, the first positioning member, and the second positioning member can position the workpiece located on the platform from all sides. It is easy to understand that the clamping component of the picking part is itself part of the structure for positioning the workpiece, and the clamping can be completed at the same time as the positioning is completed. Therefore, compared with the traditional positioning method, the detection device provided in this application combines the action of positioning the workpiece with the action of clamping the workpiece, which can save actions to improve efficiency and simplify the structure of the detection device.

[0021] Furthermore, after the picking component clamps the workpiece, the reference stage can move again along the lifting direction to avoid the movement trajectory of the picking component, so that the picking component can move to the inspection station under the drive of the transport component, so that the inspection module can inspect the workpiece.

[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. 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.

[0032] 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.

[0033] 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.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] 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. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. 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.

[0037] Please see Figure 1 , Figure 1 A top view of an inspection device provided in an embodiment of this application is shown. The inspection device 10 provided in an embodiment of this application includes an inspection apparatus 11, which is used to perform defect detection and dimensional measurement on a workpiece 20.

[0038] Furthermore, the inspection device 11 also includes a loading device (not shown in the figure, the same below) and a unloading device 12. The loading device is used to transport the workpiece 20 to be inspected to the inspection device 11, and the unloading device 12 is able to receive the workpiece 20 that has been inspected by the inspection device 11. As one example, the unloading device 12 includes a first conveying component 13 and a second conveying component 14. One of the first conveying component 13 and the second conveying component 14 is used to transport the workpiece 20 that has been judged as good, and the other is used to transport the workpiece 20 that has been judged as defective, so as to classify the workpieces 20 with different inspection results. Of course, the unloading device 12 provided in this application is not limited to including only two conveying components. For example, the unloading device 12 also includes three or more conveying components. In this case, one conveying component is used to transport the workpiece 20 that has been judged as good, and the other conveying components can be used to transport the workpieces 20 that have been judged to have different types of defects, so as to classify them.

[0039] Please see Figures 2 to 4 , Figure 2 A top view of a detection apparatus provided in an embodiment of this application is shown. Figure 3 for Figure 2 Axonometric schematic diagram of the detection device shown. Figure 4 for Figure 3 The diagram shows an isometric view of the pickup and lifting components at the first station in the detection device. An embodiment of this application provides a detection device 11 including a transfer assembly 100, a lifting assembly 200, and a detection module 300. The transfer assembly 100 is used to transport the workpiece 20 to various stations. For example, the transfer assembly 100 can transport the workpiece 20 to a station aligned with the detection module 300, at which point the detection module 300 can detect the workpiece 20 transported by the transfer assembly 100. The lifting assembly 200 can cooperate with the transfer assembly 100 to position the workpiece 20.

[0040] The transfer assembly 100 includes a pickup component 110 and a transport component 120. The pickup component 110 is disposed on the transport component 120, and the transport component 120 can drive the pickup component 110 to move. The transport component 120 includes a turntable 121 and a transport driver. The transport driver is connected to the turntable 121 to drive the turntable 121 to rotate. Multiple pickup components 110 are spaced apart on the turntable 121 around the rotation axis of the turntable 121. The transport component 120 can drive each pickup component 110 to move between the first station 101 and the inspection station 104 respectively. The lifting assembly 200 is aligned with the pickup component 110 at the first station 101 to cooperate with the pickup component 110 in positioning the workpiece 20. The inspection module 300 is aligned with the pickup component 110 at the inspection station 104, and the inspection module 300 can inspect the workpiece 20 picked up by the pickup component 110 at the inspection station 104. The lifting assembly 200 includes a lifting driver 210 and a reference platform 220. The lifting driver 210 is connected to the reference platform 220 to drive the reference platform 220 to rise and fall. The reference platform 220 includes a platform body 221, a first positioning member 222, and a second positioning member 223, both of which are located on the platform body 221. The first positioning member 222 and the second positioning member 223 are positioned facing each other and spaced apart in the reference direction S1, and the space between the first positioning member 222 and the second positioning member 223 is used to place the workpiece 20. The picking component 110 includes clamping members 111, and at least two clamping members 111 are capable of moving towards and away from each other along the clamping direction S2. When the pickup component 110 is at the first station 101, the clamping space between the clamping components 111, projected onto the reference platform 220 along the lifting direction S3, overlaps with the space between the first positioning component 222 and the second positioning component 223. The clamping direction S2 intersects with the reference direction S1. It can be understood that when the pickup component 110 is at the first station 101, because the clamping direction S2 intersects with the reference direction S1, at least two clamping components 111, the first positioning component 222, the second positioning component 223, and the platform 221 can enclose and form a receiving space for the workpiece 20 to be positioned. (See reference...) Figure 5 Combined Figure 4The clamping space between the aforementioned clamping members 111 is as follows: Figure 5 As shown in reference numeral PL1, the space between the first positioning element 222 and the second positioning element 223 is as follows: Figure 5 As shown in the reference PL2.

[0041] In the aforementioned detection device 11, the transport component 120 can drive each pickup component 110 to move to the first station 101. At the first station 101, the space between the first positioning component 222 and the second positioning component 223 is used to place the workpiece 20. When the pickup component 110 moves to the first station 101, the clamping space between the clamping components 111 overlaps with the space between the first positioning component 222 and the second positioning component 223 in the orthogonal projection of the reference platform 220 along the lifting direction S3, and the reference platform 220 can move in the lifting direction S3. Thus, by operating the reference platform 220 to move along the lifting direction S3, the first positioning component 222 and the second positioning component 223 can be positioned at the same position as the two clamping components 111 in the lifting direction S3. At this time, the first positioning component 222, the second positioning component 223, and the two clamping components 111 can position the workpiece 20. Specifically, at least two of the clamping members 111 of the pickup component 110 can move towards and away from each other along the clamping direction S2. The first positioning member 222 and the second positioning member 223 of the reference stage 220 are arranged facing each other and spaced apart in the reference direction S1. Since the clamping direction S2 intersects the reference direction S1, at least two clamping members 111, the first positioning member 222, and the second positioning member 223 can position the workpiece 20 located on the stage body 221 from all sides. It is easy to understand that the clamping member 111 of the pickup component 110 itself is part of the structure for positioning the workpiece 20, and the clamping can be completed at the same time as the positioning is completed. Thus, compared with the traditional positioning method, the detection device 11 provided in this application combines the action of positioning the workpiece 20 with the action of clamping the workpiece 20, thereby saving actions to improve efficiency and simplifying the structure of the detection device 11.

[0042] Furthermore, after the picking component 110 grips the workpiece 20, the reference stage 220 can move again along the lifting direction S3 to avoid the movement trajectory of the picking component 110, allowing the picking component 110 to move to the inspection station 104 under the drive of the transport component 120, so that the inspection module 300 can inspect the workpiece 20. As one example, the lifting driver 210 can drive the reference stage 220 to rise, so that the first positioning member 222 and the second positioning member 223 are in the same position as the clamping member 111 in the lifting direction S3. The lifting driver 210 can also drive the reference stage 220 to fall to avoid the movement trajectory of the picking component 110.

[0043] It is understood that in the alignment of the detection module 300 with the pickup component 110 at the detection station 104, the detection module 300 can be aligned with the pickup component 110 at the detection station 104 along its detection direction. For example, when the detection module 300 is configured to perform visual inspection via a camera, the detection module 300 can be aligned with the detection module 300 at the detection station 104 along the optical axis of its camera.

[0044] Please see Figure 2 and Figure 3 In one embodiment, the transport driver can be directly connected to the turntable 121 to drive the turntable 121 to rotate. Alternatively, the transport component 120 may also include a transmission element, through which the transport driver is connected to the turntable 121. For example, the transmission element may be configured as a speed reducer, through which the transport driver drives the turntable 121 to rotate.

[0045] Please see Figure 2 In one embodiment, the transport component 120 can also drive the pickup component 110 to move between the sensing station 102 and the cleaning station 103. As one example, the pickup component 110, driven by the transport component 120, sequentially passes through the first station 101, the sensing station 102, the cleaning station 103, and multiple detection stations 104. When the pickup component 110 is at the sensing station 102, the detection device 11 can sense the outer boundary of the workpiece 20 in the lifting direction S3. Thus, when the pickup component 110 moves to the cleaning station 103, the detection device 11 can adjust the cleaning position accordingly based on the outer boundary of the workpiece 20 to thoroughly clean dust and other debris from the workpiece 20, thereby improving the effectiveness of detection and reducing the false judgment rate.

[0046] Please see Figure 2 Combined Figure 1 Furthermore, driven by the transport component 120, the picking component 110 can also move to the second station 105 and the third station 106. When the picking component 110 is at the second station 105 and the third station 106, the picking component 110 is aligned with the unloading device 12, and the picking component 110 can place the inspected workpiece 20 onto the unloading device 12 for unloading. Furthermore, when the picking component 110 is at the second station 105, the picking component 110 can be aligned with the first conveying component 13. When the picking component 110 is at the third station 106, the picking component 110 can be aligned with the second conveying component 14. Thus, the workpiece 20 can be classified and unloaded according to the inspection results.

[0047] It should be noted that in some embodiments, the testing equipment 10 may not include the loading device and / or unloading device 12, in which case the workpiece 20 can be loaded and / or unloaded manually. It is understood that the lifting assembly 200 at the first station 101 can be used to receive the workpiece 20 to be tested, loaded manually or by the loading device. When the testing equipment 10 does not include the unloading device 12, the transport component 120 can carry the workpiece 20 back to the first station 101, where the workpiece 20 can be unloaded manually.

[0048] Please see Figure 4 Combined Figure 2 In one embodiment, the portion of the clamping member 111 that contacts the workpiece 20 extends outward relative to the turntable 121, thereby suspending the workpiece 20 held by the clamping member 111 relative to the turntable 121, exposing various areas of the workpiece 20 to the external environment. This facilitates the detection module 300 in detecting the workpiece 20, facilitates cleaning the workpiece 20, and also facilitates the picking member 110 in directly placing the workpiece 20 onto the unloading device 12.

[0049] Please see Figure 4 In one embodiment, the lifting assembly 200 further includes a base frame 230, on which the lifting driver 210 is disposed.

[0050] Please see Figure 4 and Figure 5 Combined Figure 2 and Figure 3 In one embodiment, the first positioning member 222 and / or the second positioning member 223 are adjustablely disposed on the stage body 221 along the reference direction S1. By adjusting the positions of the first positioning member 222 and the second positioning member 223 on the stage body 221, the first positioning member 222 and the second positioning member 223 can be adapted to workpieces 20 of different sizes, thereby improving the versatility of the detection device 11.

[0051] Furthermore, in one embodiment, the first positioning member 222 and / or the second positioning member 223 may be configured to have an active movement function, so as to actively open and clamp, and cooperate with the picking member 110 to position the workpiece 20. As one example, the lifting member also includes a clamping driver, and the number of clamping drivers is at least one. The clamping driver is connected to the first positioning member 222 and / or the second positioning member 223 to drive one of them to move closer to the other. Of course, in other embodiments, the first positioning member 222 and / or the second positioning member 223 may be detachably connected to the platform 221. By detaching and assembling the first positioning member 222 and / or the second positioning member 223, the interval between them can be adjusted to accommodate workpieces 20 of different sizes.

[0052] Please see Figure 4In one embodiment, the clamping member 111 includes a connecting rod 111a and contact portions 111b. The connecting rod 111a extends in a direction intersecting the clamping direction S2. At least two contact portions 111b are spaced apart on the side of the connecting rod 111a closest to another clamping member 111, such that when the clamping members 111 are clamped together, the contact portions 111b contact the workpiece 20. Further, the at least two contact portions 111b may be spaced apart along the extension direction of the connecting rod 111a. The connecting rod 111a may extend along the reference direction S1.

[0053] In one embodiment, the contact portion 111b may have a smooth shape to adapt to contact with workpieces 20 of various shapes.

[0054] In one embodiment, the contact portion 111b is a flexible body to adapt and fit the workpiece 20. Furthermore, as a flexible body, the contact portion 111b has the ability to deform flexibly when in contact with the workpiece 20, thus reducing the risk of damage to the workpiece 20 (e.g., scratching the workpiece 20) caused by the clamping action.

[0055] Please continue reading. Figure 4 In one embodiment, there are two clamping members 111, and each clamping member 111 has two contact portions 111b. That is, the picking member 110 has a total of four contact portions 111b, which are arranged at intervals. When the picking member 110 is clamped, the four contact portions 111b can act on the workpiece 20 on the reference platform 220 from the four apex points, so as to cooperate with the first positioning member 222 and the second positioning member 223 to jointly position the workpiece 20.

[0056] Please see Figure 2 In one embodiment, the portion of the connecting rod 111a with a contact portion 111b may be configured to extend out of the turntable 121.

[0057] like Figure 4 In one embodiment, the picking component 110 further includes a positioning driver 112 and a guide rail 113, both of which may be disposed on the transport component 120. The guide rail 113 extends along the clamping direction S2, and the two clamping members 111 are respectively slidably engaged with the guide rail 113. The positioning driver 112 is connected to the clamping members 111 to drive the clamping members 111 to move towards and away from each other.

[0058] Furthermore, the positioning driver 112 and the guide rail 113 can both be located on the turntable 121.

[0059] In one embodiment, when the picking component 110 is at the first station 101, the clamping direction S2 may be perpendicular to the reference direction S1. The lifting direction S3 is perpendicular to the reference direction S1, and the lifting direction S3 is also perpendicular to the clamping direction S2.

[0060] Because the workpiece 20 is positioned on the platform 221 by the first positioning element 222, the second positioning element 223, and the picking component 110, regardless of the size of the workpiece 20, the contact surface between the workpiece 20 and the platform 221 (i.e., the bottom surface of the workpiece 20) always has a definite position, which is at the same position as the top surface of the raised platform 221 in the lifting direction S3. However, for workpieces 20 of different sizes, since the bottom surface of the workpiece 20 serves as the reference surface, its top surface is uncertain. Therefore, refer to... Figures 6 to 8 Combined Figure 2 In one embodiment, the detection device 11 further includes a sensing component 400 and a cleaning component 500. As described above, the pickup component 110 can also be driven to move to the sensing station 102 and the cleaning station 103, with the sensing component 400 aligned with the pickup component 110 at the sensing station 102 and the cleaning component 500 aligned with the pickup component 110 at the cleaning station 103. The sensing component 400 can sense the outer boundary of the workpiece 20 (mainly the position of the top surface of the workpiece 20) so that the cleaning component 500 can clean the workpiece 20 in a targeted manner.

[0061] Furthermore, the cleaning assembly 500 may include multiple cleaning heads. The multiple cleaning heads are located in different positions relative to the pick-up component 110 at the cleaning station 103, so as to fully clean the workpiece 20 picked up by the pick-up component 110.

[0062] Please refer to 6 to Figure 8 In one embodiment, as described above, the sensing component 400 is used to sense the position of the workpiece 20 picked up by the picking component 110 at the sensing station 102 in the lifting direction S3. A portion of the structure of the sensing component 400 is movably arranged along the lifting direction S3. When this portion of the structure of the sensing component 400 is at the same height as the top surface of the workpiece 20, the sensing component 400 can be triggered. At this time, by obtaining the initial position of the sensing component 400 and the distance traveled from the initial position to the triggered position, the position of the top surface of the workpiece 20 in the lifting direction S3 can be determined. Further, the cleaning component 500 has a first cleaning head 540, which is also movably arranged along the lifting direction S3. Thus, the position of the first cleaning head 540 in the lifting direction S3 can be adjusted accordingly based on the position of the top surface of the workpiece 20, so that the first cleaning head 540 is sufficiently close to the top surface of the workpiece 20 to ensure cleaning effect.

[0063] Please see Figure 8In one embodiment, the cleaning assembly 500 further includes a second cleaning head 550, which is disposed facing the first cleaning head 540. When the pickup component 110 is in the cleaning station 103, the second cleaning head 550 and the first cleaning head 540 are respectively located on different sides of the pickup component 110 to improve the comprehensiveness of cleaning. It is understood that when the pickup component 110 is in the cleaning station 103, the second cleaning head 550 can face the bottom surface of the workpiece 20 picked up by the pickup component 110 to clean and remove dust from the bottom surface of the workpiece 20. Furthermore, since the bottom surface of the workpiece 20 is always at the same height as the top surface of the raised platform 221 in the lifting direction S3, the second cleaning head 550 can be configured to be fixedly disposed.

[0064] Please refer to it again. Figure 6 In one embodiment, the sensing component 400 includes a first sensor 440, which is aligned with the pickup component 110 at the sensing station 102. The first sensor 440 is movably disposed along the lifting direction S3, and along the lifting direction S3, the first sensor 440 is triggered when it reaches a preset distance from the top surface of the workpiece 20 picked up by the pickup component 110. That is, by obtaining the distance traveled by the first sensor 440 from its initial position along the lifting direction S3 to the triggered position, this application can determine the position of the top surface of the workpiece 20 in the lifting direction S3. It is understood that the preset distance can generally be configured to zero, but is not limited to being configured to zero.

[0065] Please see Figure 6 and Figure 7 In one embodiment, the sensing assembly 400 further includes a bracket 410, a sensing driver 420, and a connecting frame 430. The sensing driver 420 is disposed on the bracket 410 and connected to the connecting frame 430 to drive the connecting frame 430 to move along the lifting direction S3. Further, a first sensor 440 is disposed on the connecting frame 430 to move with the connecting frame 430 along the lifting direction S3. The first sensor 440 is arranged on top of the pickup member 110 at the sensing station 102 to sense the position of the top surface of the workpiece 20.

[0066] As one example, the first sensor 440 can emit a sensing medium. The first sensor 440 is triggered when it moves to a point where the sensing medium is blocked by the top surface of the workpiece 20. For example, the first sensor 440 can be configured as an infrared sensor or an optocoupler in this case. Alternatively, the first sensor 440 is triggered when the time interval between the movement of the first sensor 440 and the reflection of the sensing medium back from the top surface of the workpiece 20 is less than a preset value. For example, the first sensor 440 can be configured as an ultrasonic sensor in this case.

[0067] Please see Figure 7 In another embodiment, the sensing component 400 includes a second sensor 450 and a movable member 460. Both the second sensor 450 and the movable member 460 are disposed on the connecting frame 430, meaning they are movably arranged along the lifting direction S3. Furthermore, the movable member 460 can move relative to the second sensor 450. The movable member 460 is used to move relative to the second sensor 450 when it is abutted by the top surface of the workpiece 20, thereby triggering the second sensor 450. It is understood that when the movable member 460 is not in contact with the workpiece 20, the movable member 460 and the second sensor 450 move synchronously with the connecting frame 430, and there is no relative movement between them. When the movable member 460 contacts the workpiece 20, it is abutted by the workpiece 20, and the movable member 460 will move relative to the second sensor 450 to trigger the second sensor 450.

[0068] Furthermore, a portion of the structure of the moving part 460 is configured as an elastomer to reduce the interaction force when in contact with the workpiece 20, thereby reducing the risk of damage to the workpiece 20 from impact with the moving part 460. For example... Figure 7 As one example, the movable part 460 includes an elastic connection portion 461 and a rod portion 462. One end of the rod portion 462 is used to contact the workpiece 20, and the other end is used to trigger the second sensor 450. The elastic connection portion 461 is connected to the connecting frame 430, and the rod portion 462 passes through and is connected to the elastic connection portion 461. That is, the rod portion 462 is connected to the connecting frame 430 through the elastic connection portion 461, so that the rod portion 462 can move elastically relative to the connecting frame 430 to trigger the second sensor 450. Furthermore, the connection between the rod portion 462 and the connecting frame 430 through the elastic connection portion 461 allows the rod portion 462 to return to its initial position relative to the second sensor 450 when the external force applied to the rod portion 462 (i.e., the interaction force between the rod portion 462 and the workpiece 20) is removed.

[0069] Please see Figure 8 In one embodiment, the cleaning assembly 500 further includes a support frame 510 and a first drive module 520. The first drive module 520 is disposed on the support frame 510 and connected to the first cleaning head 540 to drive the first cleaning head 540 to move along the lifting direction S3. Therefore, the position of the first cleaning head 540 in the lifting direction S3 can be adjusted accordingly based on the sensing results of the sensing component 400, thereby improving the cleaning effect.

[0070] Please continue reading. Figure 8In one embodiment, the cleaning assembly 500 further includes a second drive module 530 connected to the stand 510. The second drive module 530 drives the stand 510 to move along the cleaning direction S4, which intersects with the lifting direction S3. By driving the stand 510 to move via the second drive module 530, the first cleaning head 540 is moved, enabling the first cleaning head 540 to perform mobile cleaning and improving the coverage of the cleaning area of ​​the first cleaning head 540 on the workpiece 20. Furthermore, the cleaning assembly 500 can also be configured with other drive modules to drive the second cleaning head 550 to move along a direction intersecting with the lifting direction S3, achieving mobile cleaning.

[0071] In one embodiment, the cleaning assembly 500 further includes a connecting pipe 560, one end of which is connected to a cleaning head and the other end of which is connected to a cleaning medium generator (not shown, the same below), allowing the cleaning medium to be conducted from the cleaning medium generator to the cleaning head for cleaning the workpiece 20. Further, there may be two connecting pipes 560, one connecting pipe 560 connecting between the first cleaning head 540 and the cleaning medium generator, and the other connecting pipe 560 connecting between the second cleaning head 550 and the cleaning medium generator.

[0072] As one example, the cleaning medium generator can be configured as an ultrasonic generator, meaning the cleaning assembly 500 uses a dry ultrasonic cleaning method to clean the workpiece 20. Of course, the cleaning assembly 500 can also use other methods to clean the workpiece 20, which will not be elaborated here.

[0073] Furthermore, the cleaning head not only has an outlet, but also a recovery port. The outlet is used to output the cleaning medium, and the recovery port is used to recover dust and other debris raised by the cleaning medium, so as to reduce the risk of raised debris falling to the detection station 104 and interfering with the detection.

[0074] Please refer to it again. Figure 2 and Figure 3 In one embodiment, the detection device 11 may include multiple detection modules 300, each corresponding one-to-one with a pickup component 110 at a plurality of detection stations 104. Furthermore, the relative position of at least one detection module 300 and its corresponding pickup component 110 at the detection station 104 is different from the relative positions of the other detection modules 300 and their corresponding pickup components 110 at the detection station 104, allowing at least one detection module 300 to detect different areas of the workpiece 20, thus improving the comprehensiveness of the detection. Of course, among the multiple detection modules 300, some detection modules 300 may have the same relative positional relationship with their corresponding pickup components 110 at the detection station 104, and these detection modules 300 may use different detection methods to detect different defects in the workpiece 20.

[0075] As one example, the multiple detection modules 300 can employ one or more of the following: line scan detection, area scan camera detection, backlight detection, front light source detection, structured light detection, dark field illumination detection, and polarized light illumination detection. Front light source detection includes, for example, ring light detection, coaxial light detection, dome light detection, and point light source detection.

[0076] Please see Figure 2 In one embodiment, the number of inspection stations 104 can be 2, 3, 4, 5, 6, 7, 8, or 9. It should be noted that the number of inspection modules 300 is not limited to be equal to the number of inspection stations 104 in the various embodiments of this application. For example, multiple inspection modules 300 can be configured at the same inspection station 104 to jointly inspect the workpiece 20 picked up by the picking component 110.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
