Description

Technical Field

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

[0002] In current manufacturing and processing, products are typically placed in specialized carriers (such as pallets or trolleys), and the products are transported by moving the carriers. When a product needs processing (such as inspection), it is removed from the carrier and transferred to a processing station, and then loaded back into the carrier after processing is completed.

[0003] The current product conveying method requires repeated actions of removing and loading products into carriers during processing, which makes the operation process cumbersome, adds extra steps, and leads to wasted time and low efficiency. Utility Model Content

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

[0005] This application provides a detection device, which includes a base frame, a detection component, and a limiting component. The base frame has a receiving cavity with an opening communicating with the outside. The detection component includes a beam frame and a detection module. The beam frame is mounted above the receiving cavity, and the detection module is movably mounted on the beam frame and faces the receiving cavity. The limiting component is located on the base frame and at least partially within the receiving cavity. The limiting component is used to limit the vehicle when the vehicle is in a preset position within the receiving cavity.

[0006] In the aforementioned testing device, the accommodating cavity of the base frame is used to house the carrier, and a limiting component for positioning the carrier is provided within the accommodating cavity. The testing component includes a testing module facing the accommodating cavity. Therefore, the testing module can test the workpiece carried by the carrier within the accommodating cavity. Furthermore, a beam frame is erected above the accommodating cavity, and the testing module is movably mounted on the beam frame, allowing the testing module to move along the beam frame to a position aligned with the workpiece in different areas of the carrier, thereby testing the workpiece in each area and improving the comprehensiveness of the testing. The testing device provided in this application allows the carrier to directly transport the workpiece into the accommodating cavity, uses the limiting component to limit the carrier, and uses the movable testing module to test the workpiece at various points on the carrier, thereby eliminating the need for workpiece handling and improving testing efficiency.

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.

[0021] See Figure 1 and Figure 2 , Figure 1 This paper shows an isometric schematic diagram of a detection device provided in one embodiment of the present application. Figure 2 for Figure 1 The diagram shows a top view of the inspection device. An embodiment of this application provides an inspection device 10 used for operations such as appearance inspection and dimensional measurement of workpieces. The inspection device 10 in this application can directly inspect the workpieces carried by the carrier, thus eliminating the need for moving the workpieces at the carrier location and improving inspection efficiency.

[0022] The detection device 10 includes a base frame 100, a detection component 200, and a limiting component 300. The base frame 100 is used to house a carrier. The limiting component 300 is located on the base frame 100 or in the area where the base frame 100 is located to limit the position of the carrier housed on the base frame 100, thereby improving the positional accuracy of the carrier. The detection component 200 is located on the base frame 100 and includes a detection module 210. The detection module 210 is movably configured to move to positions aligned with different areas of the carrier to detect the workpieces in each area. It is understood that the carrier typically carries multiple workpieces and therefore has a relatively large structural size. In the embodiments of this application, the detection module 210 is configured to be movably configured to adapt to the multiple areas of the carrier used to support the workpieces.

[0023] Please continue reading. Figure 1 and Figure 2In one embodiment, the base frame 100 is provided with a receiving cavity 101 for accommodating a carrier. The receiving cavity 101 has an opening 102 communicating with the outside, allowing the carrier to enter and exit the receiving cavity 101. A limiting component 300 is disposed on the base frame 100 and at least partially located within the receiving cavity 101. The limiting component 300 is used to limit the carrier when it is in a preset position within the receiving cavity 101, so that the carrier is accurately and stably positioned in the preset position for detection by the detection module 210. The detection component 200 includes a beam frame 220 and the detection module 210 as described above. The detection module 210 is disposed on the beam frame 220 and faces the receiving cavity 101. Therefore, the detection module 210 can detect the workpiece carried by the carrier within the receiving cavity 101. Furthermore, the beam frame 220 is erected above the receiving cavity 101, and the detection module 210 is movably mounted on the beam frame 220. The detection module 210 can move along the beam frame 220 to a position aligned with the workpieces in different areas of the carrier, thereby inspecting the workpieces in each area and improving the comprehensiveness of the inspection. The detection device 10 provided in this application allows the carrier to directly transport the workpieces into the receiving cavity 101, uses the limiting component 300 to limit the carrier, and uses the movable detection module 210 to inspect the workpieces at various points on the carrier. This eliminates the need for workpiece handling and improves inspection efficiency.

[0024] Please continue reading. Figure 1 and Figure 2 In one embodiment, the base frame 100 includes a sidewall 110 that encloses a receiving cavity 101. The sidewall 110 also serves to provide mounting support for other components of the detection device 10, such as the detection assembly 200 and the limiting assembly 300, which may be disposed on the sidewall 110.

[0025] In one embodiment, the sidewall 110 may be configured to be hollow to accommodate components such as electrical modules, pneumatic modules, and hydraulic modules included in the detection device 10.

[0026] Please see Figure 1 In one embodiment, there can be three sidewalls 110, which are connected end-to-end in the circumferential direction to enclose and form a receiving cavity 101 with an opening 102. A beam frame 220 can be erected between two opposing sidewalls 110 to span the receiving cavity 101. Figure 2 Furthermore, the multiple side walls 110 may include a first wall 111, a second wall 112 and a third wall 113, which are connected sequentially in the circumferential direction. The beam frame 220 is erected between the first wall 111 and the third wall 113 to span the receiving cavity 101.

[0027] Please refer to 3 and Figure 4In one embodiment, the detection module 210 can be configured to be movably arranged along a first direction S1, a second direction S2, and a third direction S3, wherein any two of the first direction S1, the second direction S2, and the third direction S3 intersect. This arrangement improves the flexibility of movement of the detection module 210 and facilitates detection.

[0028] Furthermore, any two of the first direction S1, the second direction S2, and the third direction S3 are perpendicular to each other.

[0029] Please see Figure 3 In one embodiment, the beam frame 220 is disposed on top of the base frame 100, such that the detection module 210 disposed on the beam frame 220 is positioned above the carrier within the accommodating cavity 101, facilitating detection. The detection assembly 200 includes a first drive module 250, which is disposed on the beam frame 220 and connected to the detection module 210 to drive the detection module 210 to move along a first direction S1, allowing the detection module 210 to move along the first direction S1 to a position aligned with a different area of ​​the carrier.

[0030] In one embodiment, the detection assembly 200 further includes a second drive module 260, which is disposed on the top of the base frame 100 and connected to the beam frame 220 to drive the beam frame 220 to move along the second direction S2, and to drive the detection module 210 disposed on the beam frame 220 to move along the second direction S2, so that the detection module 210 can move along the second direction S2 to a position aligned with a different area of ​​the vehicle. As mentioned above, the second direction S2 intersects or is perpendicular to the first direction S1.

[0031] Please see Figure 2 and Figure 3 In one embodiment, at least two beam frames 220 are arranged side by side in the second direction S2, and at least two detection modules 210 are correspondingly disposed on the at least two beam frames 220. It is understood that the range of motion of the at least two beam frames 220 can respectively correspond to different areas of the vehicle in the second direction S2, so that the detection modules 210 on each beam frame 220 are respectively responsible for detecting different areas of the vehicle, thereby improving detection efficiency.

[0032] Furthermore, there are multiple detection modules 210, with at least two detection modules 210 spaced apart along the first direction S1 on a beam frame 220. This allows different detection modules 210 on the same beam frame 220 to detect different areas of the vehicle along the first direction S1, improving detection efficiency.

[0033] Please see Figure 4In one embodiment, the detection component 200 further includes a third drive module 270 connected between the first drive module 250 and the detection module 210. The third drive module 270 drives the detection module 210 to move along a third direction S3, allowing the detection module 210 to approach and move away from the workpiece along the third direction S3, facilitating clear and accurate detection results. As mentioned above, the third direction S3 intersects or is perpendicular to the first direction S1. It is understood that when the detection device 10 is in normal detection mode, the third direction S3 may be parallel to the direction of gravity.

[0034] Furthermore, the detection assembly 200 also includes a connecting frame 230 and a mounting frame 240, with a third drive module 270 disposed on the connecting frame 230. A first drive module 250 is connected to the connecting frame 230 to drive the third drive module 270 and the detection module 210 to move along a first direction S1. The detection module 210 is disposed on the mounting frame 240, and the third drive module 270 is connected to the mounting frame 240 to drive the mounting frame 240 and the detection module 210 to move along a third direction S3.

[0035] Please see Figure 5 Combined Figure 2 In one embodiment, the detection device 10 further includes a guide wheel 400, which is rotatably disposed on the inner wall of the base frame 100. The guide wheel 400 can roll in cooperation with the outer surface of the carrier when the carrier enters and exits the receiving cavity 101, thereby improving the smoothness of the carrier entering and exiting the receiving cavity 101. Further, the guide wheel 400 can be disposed on the inner wall of the first wall 111 and the third wall 113. Even further, there can be multiple guide wheels 400, which are spaced apart along the second direction S2 on the inner wall of the first wall 111 and the inner wall of the third wall 113.

[0036] Please refer to it again. Figure 1 In one embodiment, the detection device 10 includes movable wheels 500, and a plurality of movable wheels 500 are rotatably disposed at the bottom of the base 100. This enables the base 100 as a whole to have a motion function, thus allowing it to be easily transferred to a desired position.

[0037] Please see Figure 5 In one embodiment, the base frame 100 further includes an inner extension frame 120, which is disposed on the inner wall of the side wall 110 and extends into the receiving cavity 101. Therefore, when the carrier is located in the receiving cavity 101, the projection of the inner extension frame 120 along the third direction S3 overlaps with the carrier. The limiting assembly 300 includes a lifting member 310, which is disposed on the inner extension frame 120 and can be inserted into the carrier to position the carrier.

[0038] Furthermore, the lifting component 310 has a positioning pin 311, that is, the limiting component 300 includes the positioning pin 311, which is telescopically disposed in the inner extension frame 120 along the third direction S3 for insertion and positioning with the carrier. By inserting and positioning with the carrier through the positioning pin 311, the carrier can be stably and accurately placed in the expected position, which is convenient for inspection.

[0039] Furthermore, there are multiple positioning pins 311, and each positioning pin 311 is respectively connected and engaged with the vehicle.

[0040] Please see Figure 6 In one embodiment, the lifting component 310 further includes a base frame 312, a support plate 313, a buffer 314, and a lifting driver 315. The base frame 312 is disposed on the mounting frame 240, and the lifting driver 315 is disposed on the base frame 312 and connected to the positioning pin 311 to drive the positioning pin 311 to extend and retract along a third direction S3. Further, the positioning pin 311 is disposed on the support plate 313, and the lifting driver 315 causes the positioning pin 311 to extend and retract by driving the support plate 313 to move. The buffer 314 is disposed between the base frame 312 and the support plate 313 and has a preset height in the third direction S3. When the distance between the support plate 313 and the base frame 312 is less than the preset height, the buffer 314 is used to support the support plate 313.

[0041] Furthermore, in the direction along the third direction S3 pointing to the top of the base frame 100, the cross-sectional size of the positioning pin 311 gradually decreases to a tapered shape, which facilitates insertion and positioning with the positioning hole of the carrier.

[0042] In one embodiment, the lifting component 310 further includes a guide rod 316 and a sleeve 317. The sleeve 317 is embedded in the base frame 312 and is hollow. One end of the guide rod 316 is connected to the support plate 313, and the other end passes through the sleeve 317. The insertion and engagement of the guide rod 316 and the sleeve 317 can improve the smoothness of the lifting movement of the support plate 313.

[0043] Please see Figure 2 In one embodiment, the opening 102 of the accommodating cavity 101 allows a vehicle to enter the accommodating cavity 101 along a reference direction. As one example, the reference direction may be parallel to the second direction S2.

[0044] Please see Figure 5 Combined Figure 2In one embodiment, the limiting assembly 300 further includes a stop component 320, which is used to position the vehicle in a reference direction. It is understood that the stop component 320 and the guide wheel 400 cooperate to perform coarse positioning of the vehicle, making the positioning hole on the vehicle approximately aligned with the positioning pin 311. Subsequently, the positioning pin 311 is inserted into the positioning hole to achieve fine positioning of the vehicle. It is understood that the guide wheel 400 located on the first wall 111 and the third wall 113 can position the vehicle in the first direction S1; the stop component 320 can position the vehicle in the second direction S2 (i.e., the reference direction).

[0045] Please continue reading. Figure 5 In one embodiment, at least a portion of the stop member 320 is located within the receiving cavity 101, and its orthographic projection along the reference direction overlaps with the opening 102. Thus, when the vehicle enters the receiving cavity 101 through the opening 102 along the reference direction, the vehicle will abut against a portion of the stop member 320 and will be unable to move further inward; at this point, the vehicle is positioned in the reference direction.

[0046] Please see Figure 7 Combined Figure 5 and Figure 2 In one embodiment, the stop component 320 includes a first stop 321 and a second stop 322, both of which are disposed within the inner extension frame 120. The second stop 322 is located on the side away from the opening 102 relative to the first stop 321, i.e., the second stop 322 is located inside the receiving cavity 101 relative to the first stop 321. The second stop 322 can be used to abut against the carrier, preventing further movement of the carrier into the receiving cavity 101. The first stop 321 is movable relative to the inner extension frame 120, allowing it to move to a position facing and offset from the second stop 322 in a reference direction. When the first stop 321 and the second stop 322 face each other, they can clamp and fix the carrier, preventing further movement of the carrier in the reference direction. The first stop 321 can move away from the central region of the receiving cavity 101 to offset from the second stop 322. Therefore, the first stop 321, which is offset from the second stop 322, will no longer block the movement of the vehicle along the reference direction, thus allowing the vehicle to freely enter and exit the accommodating cavity 101.

[0047] Combination Figure 2As one example, the first stop 321 has a limiting position and a clearance position. When the first stop 321 is in the limiting position, the first stop 321 is positioned opposite the second stop 322 along the reference direction (i.e., the second direction S2), and the first stop 321 extends at least partially beyond the mounting bracket 240 to abut against the vehicle. When the first stop 321 is in the clearance position, the projection of the first stop 321 along the third direction S3 is located within the mounting bracket 240, thus allowing the vehicle to freely enter and exit the receiving cavity 101.

[0048] The first stop member 321 can be configured to be telescopically disposed along a first direction S1 to move between a limiting position and a clearance position. Alternatively, see [link to relevant documentation]. Figure 7 In one embodiment, the stop member 320 further includes a bracket 323 and a flipping driver 324, the flipping driver 324 being disposed on the bracket 323. The first stop member 321 has a rotating portion 321a, which is rotatably connected to the bracket 323. Furthermore, one end of the first stop member 321 is also connected to the flipping driver 324, such that the first stop member 321 forms an approximate lever mechanism with the rotating portion 321a as the fulcrum. By driving the first stop member 321 to rotate, the flipping driver 324 can move the first stop member 321 between a limiting position and a clearance position, allowing the free end of the first stop member 321 to extend outward into or flip back into the inner extension frame 120.

[0049] Please see Figure 5 Combined Figure 2 In one embodiment, the second stop 322 may be fixed to the inner side of the mounting bracket 240 to stably block the vehicle.

[0050] Please see Figure 1 In one embodiment, the detection device 10 is disposed on a base surface (not shown, the same below), and the carrier moves on the base surface to enter and exit the receiving cavity 101. The aforementioned detection device 10 also includes a movable wheel 500 disposed at the bottom of the base frame 100, so the base frame 100 is suspended relative to the base surface by the support of the movable wheel 500. Consequently, the receiving cavity 101 formed within the base frame 100 is also spaced from the base surface. Therefore, in this embodiment, a portion of the stop member 320 (such as the wedge block 325 mentioned below) may also be disposed on the base surface, and the orthographic projection of this portion of the structure along the third direction S3 is located within the receiving cavity 101, for supporting the carrier in a preset position.

[0051] Please see Figure 1 and Figure 2 In one embodiment, the stop member 320 may further include a wedge block 325 disposed on the base surface. It is understood that the carrier may have rollers, and the wedge block 325 may abut against the rollers to restrict carrier movement.

[0052] Please refer to it again. Figure 2 In one embodiment, the number of inner extension brackets 120 is at least two, and the at least two inner extension brackets 120 are respectively disposed on the inner wall of the first wall 111 and the inner wall of the third wall 113. The number of limiting components 300 is at least two, and the at least two limiting components 300 are respectively disposed on the inner extension bracket 120 at the first wall 111 and the inner extension bracket 120 at the third wall 113.

[0053] It is understood that the first drive module 250, the second drive module 260, and the third drive module 270 can be configured as linear motor modules and other modules with linear drive functions. The lifting driver 315 and the tilting driver 324 can be configured as linear drivers of cylinders, hydraulic cylinders, and electric actuators.

[0054] 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.

[0055] 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.
