Description

Technical Field

[0001] This application relates to the technical field of processing and detection, and particularly relates to a positioning device and a detection device. Background Art

[0002] In the manufacturing process of electronic product casings, accurately opening inner wall holes is a key step to ensure the precise connection between the casing and the internal structure. The positional accuracy of these holes is crucial for the quality and functionality of the overall assembly. Therefore, after the production and processing are completed, it is necessary to strictly detect the positions of the holes on the casing to meet the high-precision assembly requirements.

[0003] Traditional detection and positioning methods rely on a cylinder to push the casing into contact with a fixed block for positioning. Although this method is simple to operate, it has limitations in the field of precision machining. Due to the accuracy deviation of the processing equipment, there are certain tolerances in the lateral and longitudinal dimensions of the casing, which may cause the actual size of the casing to deviate from the ideal size. When using cylinder positioning, this deviation may cause the detection reference to be unable to accurately align with the center of the casing, thus unable to effectively eliminate the influence brought by the processing error. In addition, how to accurately detect the side holes of the casing is also a problem that needs to be urgently solved by those skilled in the art. Summary of the Utility Model

[0080] The positioning mechanism 120 includes a connecting plate 121, a first clamping component 122 and at least two second clamping components 123.

[0081] The connecting plate 121 is connected to the side of the carrier 110 facing away from the carrying position 111.

[0082] The first clamping component 122 includes two first clamping arms 1221 and a first elastic member 1222. The two first clamping arms 1221 are arranged opposite to each other along the X-axis direction and are both slidably connected to the connecting plate 121. One end of each first clamping arm 1221 away from the connecting plate 121 is correspondingly movably arranged in the sliding hole 112 of the carrier 110 and extends out from the corresponding sliding hole 112. The two ends of the first elastic member 1222 respectively abut against one end of the two first clamping arms 1221 away from the carrier 110. The first elastic member 1222 is used to push the two first clamping arms 1221 away from each other.

[0083] The structure of the first clamping arm 1221 is generally L-shaped. One end is provided with a first clamping block 1221a, and the other end is provided with a first wedge block 1221b. The first clamping block 1221a can extend out from the sliding hole 112 to selectively position the workpiece 2000. The first wedge block 1221b is arranged in the direction away from the carrier 110, and the first wedge block 1221b is provided with an inclined surface. The first elastic member 1222 can be a spring, etc.

[0084] Each second clamping component 123 includes two second clamping arms 1231 and a second elastic member 1232. The two second clamping arms 1231 are arranged opposite to each other along the Y-axis direction perpendicular to the X-axis direction and are both slidably connected to the connecting plate 121. One end of each second clamping arm 1231 away from the connecting plate 121 is correspondingly movably arranged in the corresponding sliding hole 112 and extends out from the corresponding sliding hole 112. The two ends of the second elastic member 1232 respectively abut against one end of the two second clamping arms 1231 away from the carrier 110. The second elastic member 1232 is used to push the two second clamping arms 1231 away from each other.

[0085] The structure of the second clamping arm 1231 is generally L-shaped. One end thereof is provided with a second clamping block 1231a, and the other end is provided with a second wedge block 1231b. The second clamping block 1231a can extend out from the sliding hole 112 to selectively position the workpiece 2000. The second wedge block 1231b is arranged in a direction away from the carrier 110, and the second wedge block 1231b is provided with an inclined surface. The second elastic member 1232 can be a spring or the like.

[0086] The driving assembly 130 is connected to the side of the connecting plate 121 facing away from the carrier 110. The driving assembly 130 abuts against one end of each first clamping arm 1221 and each second clamping arm 1231 away from the carrier 110. The driving assembly 130 is configured to push the two first clamping arms 1221 in the first clamping assembly 122 closer to each other in the X-axis direction, and the two second clamping arms 1231 in each second clamping assembly 123 closer to each other in the Y-axis direction, so as to clamp and position the workpiece 2000 simultaneously in the X-axis direction and the Y-axis direction.

[0087] It can be understood that a plurality of first clamping assemblies 122 can be arranged in parallel, such as two, three, etc., and are arranged between the second clamping assemblies 123, as long as the two first clamping arms 1221 in each first clamping assembly 122 are respectively arranged on both sides of the loading position 111 in the X-axis direction and both abut against the adapted driving assembly 130. The second clamping assemblies 123 can be provided with more than two, such as four, six, etc., as long as the two second clamping arms 1231 in each second clamping assembly 123 are respectively arranged on both sides of the loading position 111 in the X-axis direction and both abut against the adapted driving assembly 130. In this way, workpieces 2000 of different sizes can be clamped and positioned, and the accuracy of clamping and positioning the workpiece 2000 can be improved. The specific number of the first clamping assemblies 122 and the second clamping assemblies 123 can be set according to the structure of the workpiece 2000 and is not limited herein.

[0088] The first clamping block 1221a on the first clamping arm 1221 and the second clamping block 1231a on the second clamping arm 1231 can be set in a plate shape or a block shape to increase the contact area between the first clamping block 1221a, the second clamping block 1231a and the workpiece 2000, thereby improving the accuracy when clamping and positioning the workpiece 2000.

[0089] The positioning device 100 provided by the embodiment of the present application can carry the workpiece 2000 through the carrier 110. Through the driving assembly 130, two first clamping arms 1221 in the first clamping assembly 122 and two second clamping arms 1231 in each second clamping assembly 123 can be driven to move towards the workpiece 2000 simultaneously from the four sides of the workpiece 2000, and then the workpiece 2000 can be clamped simultaneously from the four sides of the workpiece 2000 to position the workpiece 2000, so that the center of the workpiece 2000 remains stationary when positioning the workpiece 2000, and further evenly distribute the machining tolerances in all directions of the workpiece 2000, improving the accuracy when detecting the workpiece 2000. After the driving assembly 130 moves away from the first clamping arm 1221 and the second clamping arm 1231, the two first clamping arms 1221 of the first elastic member 1222 move away from each other, and the second elastic member 1232 pushes the corresponding two second clamping arms 1231 to move away from each other to release the workpiece 2000, with simple operation and convenient use. The positioning device 100 provided by the embodiment of the present application can position the workpiece 2000 based on the center of the workpiece 2000, thereby eliminating the influence of machining errors on the detection of the workpiece 2000, which is beneficial to improving the detection accuracy.

[0090] In some embodiments, please refer to Figure 1 and Figure 2 , the driving assembly 130 includes a support plate 131, at least three pushing members 132, at least three third elastic members 133 and at least three rotating arms 134.

[0091] The support plate 131 is connected to the side of the connecting plate 121 facing away from the carrier 110. The support plate 131 can be in a "U" - shaped structure, with both ends connected to the carrier 110 and the middle spaced from the carrier 110 to reserve a moving space for structures such as the pushing member 132 and the third elastic member 133.

[0092] Each pushing member 132 is disposed between the support plate 131 and the connecting plate 121. One end of each pushing member 132 away from the connecting plate 121 movably penetrates the support plate 131 along the Z-axis direction. One of the pushing members 132 is disposed along the X-axis direction and is correspondingly disposed with the first clamping assembly 122. The end of the pushing member 132 correspondingly disposed with the first clamping assembly 122 away from the support plate 131 is in inclined surface abutment with the two first clamping arms 1221. At least two pushing members 132 are disposed along the Y-axis direction and are respectively correspondingly disposed with each second clamping assembly 123 one by one. The end of the pushing member 132 correspondingly disposed with the second clamping assembly 123 away from the support plate 131 is in inclined surface abutment with the two second clamping arms 1231. The pushing member 132 may include a connecting column 1321 and a pushing block 1322. The connecting column 1321 is slidably inserted into the support plate 131 along the Z-axis direction. The pushing block 1322 is connected to one end of the connecting column 1321 away from the support plate 131. Two wedge-shaped surfaces are symmetrically disposed on one side of the pushing block 1322 for abutting against the first clamping arm 1221 or the second clamping arm 1231. It can be understood that the two wedge-shaped surfaces on the pushing block 1322 for abutting against the first clamping arm 1221 are spaced along the X-axis direction, and the two wedge-shaped surfaces on the pushing block 1322 for abutting against the second clamping arm 1231 are spaced along the Y-axis direction, so that the pushing block 1322 correspondingly abuts against the first wedge-shaped block 1221b on the first clamping arm 1221 or the second wedge-shaped block 1231b on the second clamping arm 1231. When the pushing block 1322 corresponding to the first clamping arm 1221 moves towards the first clamping arm 1221 and the pushing block 1322 corresponding to the second clamping arm 1231 moves towards the first clamping arm 1221, the pushing block 1322 can push the two first clamping arms 1221 or the two first clamping arms 1221 to approach each other through inclined surface cooperation, and further clamp the workpiece 2000 by the two first clamping arms 1221 and the two first clamping arms 1221. The number of the pushing members 132 can be set to three, five, seven, etc., and is consistent with the sum of the numbers of the first clamping assembly 122 and the second clamping assembly 123.

[0093] Each third elastic member 133 is respectively sleeved on one end of each pushing member 132 away from the connecting plate 121, and both ends of each third elastic member 133 respectively abut against the support plate 131 and one end of the pushing member 132 away from the support plate 131. The third elastic member 133 is used to push the pushing member 132 to move along the Z-axis direction, so that the pushing member 132 pushes the corresponding two first clamping arms 1221 or two second clamping arms 1231 to approach each other to clamp the workpiece 2000. The third elastic member 133 can be a spring, etc. It can be understood that the third elastic member 133 can be sleeved on the connecting column 1321. One end of the third elastic member 133 abuts against the support plate 131, and the other end abuts against the pushing block 1322 to push the pushing member 132 to move along the Z-axis direction.

[0094] Each rotating arm 134 abuts against the side of the support plate 131 away from the connecting plate 121 and is respectively rotatably connected to a pushing member 132. The rotating arm 134 is used to push the pushing member 132 to move in the reverse direction of the Z-axis, so that the first elastic member 1222 pushes the two first clamping arms 1221 away from each other, and the second elastic member 1232 pushes the two second clamping arms 1231 away from each other to release the workpiece 2000. The rotating arm 134 can be a columnar structure. The number of rotating arms 134 can be three, five, seven, etc., which is consistent with the number of pushing members 132. The pushing member 132 is rotatably connected to the connecting column 1321 and is used to pull the connecting column 1321 and the pushing block 1322 to move away from the first clamping arm 1221 or the second clamping arm 1231, so that the first elastic member 1222 can push the two first clamping arms 1221 away from each other, and the second elastic member 1232 pushes the two second clamping arms 1231 away from each other to release the workpiece 2000.

[0095] In some embodiments, please refer to Figures 1 to 3 , one end of the rotating arm 134 connected to the pushing member 132 has adjacent first abutting surfaces 1341 and second abutting surfaces 1342. The distance between the first abutting surface 1341 and the connecting position of the rotating arm 134 and the pushing member 132 is greater than the distance between the second abutting surface 1342 and the connecting position of the rotating arm 134 and the pushing member 132. When the first abutting surface 1341 abuts against the support plate 131, the rotating arm 134 pulls the pushing member 132 to move in the reverse direction of the Z-axis. When the second abutting surface 1342 abuts against the support plate 131, the third elastic member 133 pushes the pushing member 132 to move in the Z-axis direction. In this way, only by rotating the rotating arm 134, the pushing member 132 can be driven to move closer to or away from the first clamping arm 1221 or the second clamping arm 1231, so that the two first clamping arms 1221 and the two second clamping arms 1231 clamp or release the workpiece 2000.

[0096] In some embodiments, please refer to Figure 1 and Figure 2, the connecting plate 121 is provided with at least three sliding grooves 1211 and at least three limiting holes 1212. Each sliding groove 1211 is opened on the side of the connecting plate 121 close to the bearing member 110. One of the sliding grooves 1211 extends along the X-axis direction for accommodating two first clamping arms 1221, and at least two sliding grooves 1211 extend along the Y-axis direction for respectively accommodating two second clamping arms 1231 in each second clamping assembly 123. Each limiting hole 1212 extends along the Z-axis direction. Each limiting hole 1212 corresponds to and communicates with a sliding groove 1211 and is correspondingly arranged with a pushing member 132. One end of each pushing member 132 away from the support plate 131 is slidably arranged in the corresponding limiting hole 1212, and the limiting hole 1212 is used for limiting the pushing member 132. The number of sliding grooves 1211 can be three, five, seven, etc. The number of sliding grooves 1211 arranged along the X-axis direction is one, and the number of sliding grooves 1211 arranged along the Y-axis direction can be two, four, six, etc. The number of limiting holes 1212 can be set to three, five, seven, etc. The positions and structures of the limiting holes 1212 correspond to the pushing blocks 1322 of the pushing members 132, so as to limit the pushing members 132 in the X-Y plane while allowing the pushing members 132 to slide, and improve the accuracy of the positions of the pushing members 132 when pushing the first clamping arms 1221 or the second clamping arms 1231.

[0097] In some embodiments, please refer to Figure 2 and Figure 3 , the driving assembly 130 further includes a handle 135. The handle 135 is fixedly connected to a plurality of rotating arms 134. The handle 135 is used to drive the plurality of rotating arms 134 to move synchronously. The handle 135 can be a columnar structure. By the handle 135, the plurality of rotating arms 134 can be driven to rotate synchronously, and then the plurality of rotating arms 134 can synchronously drive the pushing members 132 to move closer to or away from the first clamping arms 1221 or the second clamping arms 1231, so that the two first clamping arms 1221 or the two second clamping arms 1231 can simultaneously clamp or release the workpiece 2000, simplify the operation steps, improve the positioning efficiency, and can also make the two first clamping arms 1221 or the two second clamping arms 1231 simultaneously clamp the workpiece 2000 from the peripheral side of the workpiece 2000, so that when positioning the workpiece 2000, the central position of the workpiece 2000 is located at the center of the bearing position 111.

[0098] The working process of the positioning device 100 provided by the embodiment of the present application is generally as follows:

[0099] First, place the workpiece 2000 on the loading position 111 of the loading member 110. Then, drive the plurality of rotating arms 134 to rotate through the handle 135, so that the second abutting surface 1342 of the rotating arm 134 abuts against the support plate 131. At this time, the third elastic member 133 pushes the pushing member 132 to move along the Z-axis direction, and the pushing member 132 pushes the corresponding two first clamping arms 1221 or the corresponding two second clamping arms 1231 to approach each other. The two first clamping arms 1221 in the first clamping assembly 122 and the two second clamping arms 1231 in each second clamping assembly 123 move synchronously towards the workpiece 2000, and then clamp the workpiece 2000 from the peripheral side of the workpiece 2000 to position the workpiece 2000. The two first clamping arms 1221 in the first clamping assembly 122 and the two second clamping arms 1231 in each second clamping assembly 123 clamp the workpiece 2000 synchronously, which can move the central position of the workpiece 2000 to the center of the loading position 111, so as to evenly distribute the machining tolerance of the workpiece 2000 around the workpiece 2000, facilitating subsequent detection of the workpiece 2000.

[0100] When loosening the workpiece 2000, drive the plurality of rotating arms 134 to rotate through the handle 135, so that the second abutting surface 1342 of the rotating arm 134 abuts against the support plate 131, and the pushing member 132 moves away from the first clamping arm 1221 or the second clamping arm 1231. At this time, the two first clamping arms 1221 move away from each other under the pushing of the first elastic member 1222, and the corresponding two second clamping arms 1231 move away from each other under the pushing of the second elastic member 1232 to loosen the workpiece 2000.

[0101] Please refer to Figure 4 and Figure 5 , this embodiment of the present application further provides a detection device 1000 for detecting the position of the side hole 2001 of the workpiece 2000. The workpiece 2000 can be the rear shell, middle frame, etc. of a mobile phone or a tablet computer. The side hole 2001 can be a machining hole, a speaker hole, etc. on the side wall of the workpiece 2000. The number of side holes 2001 can be multiple, such as five, six, eleven, etc. The side holes 2001 can be opened on the same side wall or different side walls of the workpiece 2000. The specific number and position are set according to actual design requirements and are not limited herein. The detection device 1000 includes the positioning device 100 and the detection device 200 in the above embodiment.

[0102] Please refer to Figure 2 , a plurality of positioning holes 113 spaced from the loading position 111 are provided on the loading member 110 in the positioning device 100. The number of positioning holes 113 can be two, three, four, etc. The positioning holes 113 correspond to the side positions of the loading position 111.

[0103] Please refer to Figure 4 ,Figure 5 and Figure 6 As shown in FIGS. Figure 5 and Figure 6 , the detection device 200 includes a detection frame 210, a detection component 220, and a test piece 230. A plurality of positioning pins 211 corresponding to the plurality of positioning holes 113 one by one are provided on the detection frame 210. The detection frame 210 is inserted into the corresponding positioning holes 113 through the positioning pins 211 to be connected to the carrier 110 and disposed above the carrying position 111. The detection frame 210 is provided with a plurality of detection holes 212. The detection component 220 is movably connected to one side of the detection frame 210 close to the carrying position 111. The detection component 220 corresponds to the side hole 2001 of the workpiece 2000. The test piece 230 is used to be inserted into the detection hole 212 to push the detection component 220 to move towards the side hole 2001, thereby detecting the position of the side hole 2001.

[0104] Please also refer to Figure 8 As shown in FIG. Figure 8 , the detection frame 210 may be a plate-like structure. When the detection frame 210 is placed on the carrier 110, the detection frame 210 covers the workpiece 2000 located at the carrying position 111. The positioning pin 211 may be a columnar structure, and its quantity is consistent with that of the positioning holes 113. When the detection piece 221 is disposed on the upper side of the carrier 110, the positioning pin 211 is inserted into the corresponding positioning hole 113 to position the detection frame 210. The number of the detection holes 212 may be two, three, etc., and the specific quantity and position correspond to the detection component 220. The test piece 230 may be a block, a strip, etc. During detection, the operator inserts the test piece 230 into the detection hole 212, and then the test piece 230 pushes the detection component 220 to move towards the side hole 2001 to detect the position of the side hole 2001. It can be understood that when the position of the side hole 2001 meets the requirements, the detection component 220 can be inserted into the corresponding side hole 2001. When the position of the side hole 2001 does not meet the requirements, the detection component 220 cannot be inserted into the corresponding side hole 2001. At this time, the test piece 230 cannot be completely inserted into the detection hole 212 either. The operator can identify whether the position of the side hole 2001 meets the requirements according to whether the test piece 230 can be completely inserted into the detection hole 212. The operation is simple and the detection is convenient.

[0105] The detection device 1000 provided by the embodiment of the present application can position the workpiece 2000 with the center of the workpiece 2000 as a reference through the above-mentioned positioning device 100. The detection frame 210 in the detection device 200 can insert the positioning pin 211 into the positioning hole 113 on the carrier 110, and then set the detection frame 210 on the upper side of the carrier 110 and cover the workpiece 2000. When the detection frame 210 covers the workpiece 2000, the detection component 220 corresponds to the side hole 2001 of the workpiece 2000. Insert the test piece 230 into the detection hole 212 of the detection frame 210, so that the test piece 230 pushes the detection component 220 to move towards the side hole 2001, and then the position of the side hole 2001 can be detected.

[0106] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 5 , a plurality of positioning blocks 114 are further arranged on the carrier 110 of the positioning device 100. The plurality of positioning blocks 114 are arranged around the bearing position 111 and are used to position the detection frame 210. Four positioning blocks 114 can be arranged and are arranged at the four corners of the bearing position 111. The structure of the positioning block 114 can be L-shaped to position the four corners of the detection frame 210. By arranging the positioning blocks 114, the detection frame 210 can be preliminarily positioned, which is convenient for the positioning pin 211 of the detection frame 210 to be inserted into the positioning hole 113, and the positioning efficiency is improved.

[0107] In some embodiments, please refer to Figure 4 , Figure 6 and Figure 8, the detection component 220 includes a detector 221 and a fourth elastic member 222. The detector 221 is slidably connected to one side of the detection frame 210 close to the loading position 111. One end of the detector 221 corresponding to the side hole 2001 is provided with a probe 2211, and the radius of the probe 2211 is smaller than the radius of the side hole 2001. One end of the detector 221 away from the detection hole 212 is provided with a first inclined surface 2212, and the first inclined surface 2212 is disposed opposite to the detection hole 212. The test piece 230 is provided with a second inclined surface 231. When the test piece 230 is inserted into the detection hole 212, the second inclined surface 231 pushes against the first inclined surface 2212 to move the detector 221 towards the side hole 2001, and further move the probe 2211 towards the side hole 2001. The fourth elastic member 222 is sleeved on the detector 221, and both ends of the fourth elastic member 222 are respectively connected to the detection frame 210 and the detector 221. The fourth elastic member 222 is used to push the detector 221 to move away from the side hole 2001. The fourth elastic member 222 can be a spring or the like. When the test piece 230 is inserted into the detection hole 212, the second inclined surface 231 pushes against the first inclined surface 2212 to make the detection needle insert into the corresponding side hole 2001, and then detect the side hole 2001. After the detection is completed, the test piece 230 is removed from the detection hole 212, and the fourth elastic member 222 pushes the detector 221 away from the corresponding side hole 2001.

[0108] In some embodiments, please refer to Figure 4 , Figure 6 and Figure 8, the number of the detection components 220 is set to be multiple, the multiple detection components 220 are arranged at intervals and are parallel to each other. The test piece 230 includes a first test piece 232 and a second test piece 233. The length of the first test piece 232 is greater than the distance between the two detection pieces 221 that are farthest apart, so that the first test piece 232 can simultaneously push all the detection pieces 221 to move. The length of the second test piece 233 is less than the distance between two adjacent detection pieces 221, and the second test piece 233 is used to push one detection piece 221 to move. The number of the detection components 220 can be set to be multiple, such as five, six, eleven, etc. The specific number and position correspond to the side holes 2001 of the workpiece 2000, respectively, for detecting each side hole 2001 of the workpiece 2000. During detection, first insert the first test piece 232 into the detection hole 212. The first test piece 232 can simultaneously push multiple detection pieces 221 to move. If the positions of the side holes 2001 corresponding to each detection piece 221 meet the requirements at this time, the first test piece 232 can be completely inserted into the detection hole 212, and all the side holes 2001 are qualified, then there is no need to use the second test piece 233 for detection. If there is an unqualified situation in the position of the side hole 2001, whether it is one or multiple side holes 2001 that are unqualified, the first test piece 232 cannot be completely inserted into the detection hole 212. At this time, it is necessary to use the second test piece 233 to insert into the detection hole 212 to push the detection pieces 221 to move one by one and detect each side hole 2001 separately. In this way, the detection efficiency can be effectively improved.

[0109] In some embodiments, please refer to Figure 4 , Figure 5 and Figure 7 , a plurality of fixing caps 213 are arranged on the side of the detection frame 210 away from the bearing member 110. A fifth elastic member 214 is arranged in each fixing cap 213. Each positioning pin 211 is movably connected to the detection frame 210, and each positioning pin 211 correspondingly abuts against a fifth elastic member 214. The fifth elastic member 214 is used to elastically push the positioning pin 211 away from the fixing cap 213. The number and position of the fixing caps 213 correspond to the positioning pins 211. An accommodation space is arranged inside the fixing cap 213, and the fifth elastic member 214 is arranged in the accommodation space. The fifth elastic member 214 can be a spring or the like, and the sum of the elastic forces of the plurality of fifth elastic members 214 is less than the gravity of the detection piece 221. A protrusion can be arranged at one end of the positioning pin 211 that abuts against the fifth elastic member 214, which can abut against the fifth elastic member 214 and the detection frame 210 at the same time to prevent the positioning pin 211 from slipping out of the detection frame 210. The radius of one end of the positioning pin 211 for inserting into the positioning hole 113 is less than the radius of the positioning hole 113, and the radius gradually increases along the Z-axis direction until it is greater than the radius of the positioning hole 113.

[0110] During positioning, the detection frame 210 is placed on the upper side of the bearing member 110. The positioning pin 211 is inserted into the corresponding positioning hole 113 until the position where the radius of the positioning pin 211 is the same as that of the positioning hole 113 abuts against the orifice of the positioning hole 113. At this time, the positioning pin 211 no longer moves into the positioning hole 113, and the detection frame 210 continues to move towards the bearing member 110 until it abuts against the bearing member 110. At this time, the fifth elastic member 214 pushes the positioning pin 211 to maintain the stability of positioning, and the gravity of the detection frame 210 is greater than the sum of the elastic forces of the multiple fifth elastic members 214, so that the detection frame 210 can abut against the bearing member 110.

[0111] During disassembly, the detection frame 210 is moved, and the detection frame 210 drives the multiple positioning pins 211 to move out of the corresponding positioning holes 113, and then the disassembly can be completed. By providing the fixing cap 213 and the fifth elastic member 214, and making the positioning pin 211 slidably connected to the detection frame 210, when the positioning pin 211 is inserted into the positioning hole 113 for positioning, the positioning pin 211 can be prevented from getting stuck in the positioning hole 113, reducing the difficulty of positioning and disassembly.

[0112] The working process of the detection device 1000 provided by the embodiment of the present application is generally as follows:

[0113] First, the workpiece 2000 is positioned by the positioning device 100, then the detection frame 210 is installed on the bearing member 110, and the detection frame 210 is positioned by the cooperation of the positioning pin 211 and the positioning hole 113. After positioning, the first test piece 232 is inserted into the detection hole 212 to push the multiple detection pieces 221 for detecting the side holes 2001 on the same side of the workpiece 2000 to move, so as to simultaneously detect the side holes 2001 on the same side of the workpiece 2000.

[0114] If the first test piece 232 is completely inserted into the detection hole 212, it means that the positions of all the side holes 2001 on this side meet the requirements, and there is no need to use the second test piece 233 for detection. If the first test piece 232 cannot be completely inserted into the detection hole 212, it means that the position of at least one side hole 2001 on this side does not meet the requirements. At this time, the second test piece 233 needs to be inserted into the detection hole 212 to push the detection pieces 221 to move one by one to individually detect each side hole 2001.

[0115] After the detection is completed, the detection frame 210 is removed from the bearing member 110, and then the positioning device 100 releases the workpiece 2000.

[0116] For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
