For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0067] In order to facilitate the understanding and description of the embodiments of the present application, a three-dimensional coordinate system is established in some of the drawings, such as Figure 1 As shown, the X-axis direction is the first direction, the Y-axis direction is the second direction, and the Z-axis direction is the third direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0068] See Figure 1 and Figure 2, an embodiment of the present application provides a detection device 100 for detecting the size of a side hole 201 of a workpiece 200. The workpiece 200 can be the shell of an electronic product, and the side hole 201 can be a speaker hole, a charging hole, a button hole, etc. In this embodiment, the workpiece 200 is the shell of a mobile phone, and the side hole 201 is a speaker hole. There are multiple side holes 201 on the workpiece 200, and the multiple side holes 201 are located on the same straight line. The detection device 100 includes a support base 10, two positioning mechanisms 20 carried on the support base 10 at intervals, a moving mechanism 30 carried on the support base 10 and arranged between the two positioning mechanisms 20, and a checking fixture 40 connected to the moving mechanism 30.

[0069] The support base 10 is a plate-shaped structure, and the plate-shaped support base 10 can provide stable support for the positioning mechanism 20 .

[0070] Two positioning mechanisms 20 are carried on the support base 10 at intervals, and each positioning mechanism 20 carries a workpiece 200 .

[0071] See Figure 1 、 Figure 2 and Figure 3 The positioning mechanism 20 includes a bearing seat 21 connected to the support seat 10, a plurality of positioning blocks 22 and a plurality of holding components 23 arranged on the side of the bearing seat 21 away from the support seat 10. The plurality of positioning blocks 22 are arranged at the four corners near the bearing seat 21 and support and position the workpiece 200. Each holding component 23 is arranged adjacent to the corresponding positioning block 22.

[0072] The supporting seat 21 is a plate-like structure, and the number of positioning blocks 22 can be four, six, eight, etc. In this embodiment, there are four positioning blocks 22, which are respectively arranged at the four corners of the support seat 10 to support and fix the four corners of the workpiece 200. The positioning block 22 is provided with a groove adapted to the workpiece 200 to improve the stability of the positioning block 22 in supporting the workpiece 200.

[0073] Each pressing assembly 23 includes a support member 231 connected to the support base 21, a rotating shaft 232 slidably connected to the support member 231, a fourth elastic member 233 sleeved on the rotating shaft 232, and a pressing claw 234 connected to the end of the rotating shaft 232 away from the support base 21. The two ends of the fourth elastic member 233 respectively abut the support member 231 and the rotating shaft 232 to push the rotating shaft 232 toward the support base 21, thereby driving the pressing claw 234 to press the workpiece 200 located on the positioning block 22 to fix the workpiece 200. The pressing assemblies 23 can be provided with four, six, eight, etc. In this embodiment, four pressing assemblies 23 are provided, respectively disposed near the two side edges of the support base 21 in the Y-axis direction. The support member 231 is generally L-shaped. One end of the support member 231 connected to the support base 21 extends along the Y-axis to support the workpiece 200 and improve the stability of the connection between the support member 231 and the support base 21. The other end of the support member 231 extends along the Z-axis. The main body of the rotating shaft 232 is a columnar structure, with a cap-shaped protrusion provided at the end away from the pressure claw 234. The rotating shaft 232 can rotate about the Z-axis and slide along the Z-axis within the support member 231. The fourth elastic member 233 is a spring used to push the rotating shaft 232 in the opposite direction of the Z-axis. The pressure claw 234 is a barbed structure that matches the structure of the workpiece 200 to press and hold the workpiece 200.

[0074] It can be understood that the two positioning mechanisms 20 are used to carry and position the two workpieces 200. When the two workpieces 200 are placed on the corresponding positioning mechanisms 20, the side holes 201 on the two workpieces 200 are arranged opposite to each other. Before the workpieces 200 are placed on the positioning mechanisms 20, the pressure claws 234 are rotated to open the pressure claws 234 (such as Figure 2 ), and then the workpiece 200 is placed on the positioning block 22 on the support base 21. After the workpiece 200 is placed, the pressure claw 234 is first pulled upward, which drives the rotating shaft 232 upward. The rotating shaft 232 compresses the fourth elastic member 233. The pressure claw 234 is then rotated so that the pressure claw 234 corresponds to the workpiece 200 in the Z-axis direction. The pressure claw 234 is released, and the fourth elastic member 233 pushes the rotating shaft 232 in the opposite direction of the Z-axis, causing the pressure claw 234 to press the workpiece 200, thus completing the positioning of the workpiece 200.

[0075] See Figure 1 、 Figure 4 and Figure 5The moving mechanism 30 is arranged between the two positioning mechanisms 20 and connected to the two positioning mechanisms 20. The moving mechanism 30 includes a lateral moving component 31 connected to the two positioning mechanisms 20, a vertical adjustment component 32 connected to the lateral moving component 31, a longitudinal moving component 33 arranged in the vertical adjustment component 32, and a fixed component 34 arranged on the side of the longitudinal moving component 33 away from the lateral moving component 31. The longitudinal moving component 33 moves between the two positioning mechanisms 20 along the X-axis direction under the guidance of the lateral moving component 31, and the fixed component 34 moves along the Y-axis direction under the guidance of the longitudinal moving component 33.

[0076] See Figure 1 、 Figure 4 、 Figure 5 and Figure 6 The lateral movement assembly 31 includes a guide rod 311 connected to the two positioning mechanisms 20 and extending along the X-axis, and a first sliding seat 312 slidably connected to the guide rod 311. The first sliding seat 312 moves between the two positioning mechanisms 20 along the guide rod 311. The longitudinal movement assembly 33 is connected to the first sliding seat 312 via the vertical adjustment assembly 32. The guide rod 311 is a rod-shaped structure, and the first sliding seat 312 is a plate-shaped structure. The guide rod 311 passes through the first sliding seat 312, and the first sliding seat 312 can slide along the guide rod 311. In this embodiment, to improve the stability of the first sliding seat 312 during sliding, two guide rods 311 are provided, spaced apart along the Y-axis and parallel to each other.

[0077] Both ends of the first sliding seat 312 in the Y-axis direction are provided with limiting pins 3121 extending along the Y-axis direction. The limiting pins 3121 are columnar structures.

[0078] The lateral movement assembly 31 also includes two first elastic members 313 that are sleeved onto the guide rods 311. The two first elastic members 313 are respectively disposed on either side of the first sliding seat 312 in the X-axis direction and correspond one-to-one with the two positioning mechanisms 20. The two ends of each first elastic member 313 respectively abut the first sliding seat 312 and the corresponding positioning mechanism 20, and the first elastic member 313 pushes the first sliding seat 312 away from the corresponding positioning mechanism 20. The first elastic member 313 is a spring. In this embodiment, two first elastic members 313 are disposed on each guide rod 311, i.e., when two guide rods 311 are provided, four first elastic members 313 are provided. By providing the first elastic members 313 on both sides of the first sliding seat 312, the first sliding seat 312 can be pushed away from the positioning mechanism 20. Specifically, after the inspection fixture 40 detects the side hole 201 of the workpiece 200, the inspection fixture 40 is moved away from the workpiece 200, facilitating the reset of the inspection fixture 40.

[0079] The vertical adjustment assembly 32 is disposed on a side of the first sliding seat 312 away from the support seat 10 , and the longitudinal movement assembly 33 is connected to a side of the vertical adjustment assembly 32 away from the first sliding seat 312 .

[0080] The vertical adjustment assembly 32 includes a floating plate 321 that covers the side of the first sliding seat 312 facing away from the support seat 10, an adjusting member 322 that is movably inserted into the first sliding seat 312 from the side of the first sliding seat 312 toward the support seat 10 and connected to the floating plate 321, and a plurality of second elastic members 323 disposed between the first sliding seat 312 and the floating plate 321. The second elastic members 323 push the floating plate 321 away from the first sliding seat 312 in the Z-axis direction. The adjusting member 322 drives the floating plate 321 toward or away from the first sliding seat 312, thereby adjusting the position of the floating plate 321 in the Z-axis direction, and thereby adjusting the position of the gauge 40 in the Z-axis direction.

[0081] The floating plate 321 is provided with a strip hole 3211 at both ends in the Y-axis direction. The two strip holes 3211 correspond to the two limit pins 3121 respectively. The two limit pins 3121 are movably set in the corresponding strip holes 3211 respectively. The limit pins 3121 and the strip holes 3211 cooperate with each other to limit the floating plate 321 when the adjusting member 322 adjusts the position of the floating plate 321 in the Z-axis direction.

[0082] The floating plate 321 is a cover-shaped structure. Both ends of the floating plate 321 extend along the Z-axis direction. Two strip holes 3211 are set at both ends of the floating plate 321 and are sleeved on the corresponding limit pins 3121. When the floating plate 321 moves along the Z-axis direction, the limit pins 3121 can cooperate with the strip holes 3211 to limit the floating plate 321. At the same time, through the cooperation between the limit pins 3121 and the strip holes 3211, the floating plate 321 can also be prevented from separating from the first sliding seat 312.

[0083] The adjusting member 322 is a bolt with a nut. The adjusting member 322 slides through the first sliding seat 312 and is threadedly connected to the floating plate 321. The second elastic member 323 is a spring. Two, four, or other second elastic members 323 can be provided. In this embodiment, two second elastic members 323 are provided. It will be understood that both the first sliding seat 312 and the floating plate 321 have grooves for accommodating the second elastic members 323. This accommodates the second elastic members 323 when the first sliding seat 312 and the floating plate 321 are close to each other.

[0084] The specific adjustment method is as follows: To adjust the floating plate 321 downward, tighten the adjusting member 322. The adjusting member 322 pulls the floating plate 321 toward the first sliding seat 312. The floating plate 321 and the first sliding seat 312 then compress the second elastic member 323, completing the downward movement of the floating plate 321. To adjust the floating plate 321 upward, loosen the adjusting member 322. The second elastic member 323 pushes the floating plate 321 upward away from the first sliding seat 312. To facilitate adjustment of the adjusting member 322, a through-hole can be provided in the support base 10. During adjustment, an adjustment tool can be inserted through the through-hole to adjust the adjusting member 322.

[0085] The longitudinal moving assembly 33 includes a slide rail 331 disposed on a side of the floating plate 321 away from the first slide seat 312 and extending along the Y-axis direction, a second slide seat 332 slidably connected to the slide rail 331 , and two stoppers 334 respectively disposed at both ends of the slide rail 331 .

[0086] A positioning bead 333 is provided on the side of the slide rail 331 facing away from the first sliding seat 312. A positioning groove 3321 is provided on the side of the second sliding seat 332 facing the slide rail 331, which cooperates with the positioning bead 333. When the second sliding seat 332 slides along the slide rail 331, the positioning bead 333 cooperates with the positioning groove 3321 to position the second sliding seat 332. The positioning bead 333 is a positioning structure composed of a spring and a ball. In this embodiment, there are two positioning beads 333. The second sliding seat 332 is a block-shaped structure that is connected to the slide rail 331 and can slide along the slide rail 331. The second sliding seat 332 is provided with multiple positioning grooves 3321, such as two, three, or four. In this embodiment, there are four positioning grooves 3321, which are arranged along the Y-axis. The distance between two adjacent positioning grooves 3321 is the same as the distance between two adjacent side holes 201. When inspecting the side hole 201, the second sliding seat 332 is slid along the slide rail 331 so that one of the positioning grooves 3321 engages with one of the positioning beads 333 to position the second sliding seat 332. At this point, the detection member 41 corresponds to one of the side holes 201, making it easier for the detection member 41 to inspect the side hole 201. When the next side hole 201 needs to be inspected, the second sliding seat 332 is slid along the slide rail 331 so that the next positioning groove 3321 engages with the positioning bead 333 to further position the second sliding seat 332.

[0087] Two stoppers 334 are connected to the slide rail 331 and are adjustable along the Y-axis. They are used to limit the range of movement of the second slide seat 332 along the Y-axis. The stoppers 334 are block-shaped and connected to the slide rail 331 via bolts and other structural members. In this embodiment, the stoppers 334 are provided with waist-shaped holes (not shown). To adjust the position of the stoppers 334, first loosen the bolts, then move the stoppers 334 along the waist-shaped holes. Once the stoppers 334 are in the desired position, tighten the bolts.

[0088] See Figure 1 、 Figure 5 and Figure 6 The fixing assembly 34 includes a fixing part 341 connected to the side of the second sliding seat 332 away from the sliding rail 331, a connecting pin 342 slidably inserted into the fixing part 341, a third elastic part 343 sleeved on the connecting pin 342, and a rotating part 344 connected to one end of the connecting pin 342 extending out of the fixing part 341.

[0089] The fixing member 341 is provided with a receiving groove 3411 whose opening faces the second sliding seat 332, the connecting pin 342 passes through the bottom of the receiving groove 3411 and extends out of the fixing member 341, and a protrusion 3421 is provided at one end of the connecting pin 342 arranged in the receiving groove 3411. The third elastic member 343 is arranged in the receiving groove 3411 and its two ends respectively abut against the protrusion 3421 and the bottom of the receiving groove 3411. The inspection tool 40 is connected to the rotating member 344, and the rotating member 344 can drive the inspection tool 40 to rotate about the Z-axis direction to adjust the position of the inspection member 41; wherein, the third elastic member 343 pushes the connecting pin 342 to move in the opposite direction of the Z-axis direction, thereby driving the rotating member 344 to abut against the fixing member 341 to position the rotating member 344.

[0090] In this embodiment, the fixing member 341 is a block-shaped structure, the opening of the accommodating groove 3411 faces the second sliding seat 332, the connecting pin 342 is a columnar structure, the third elastic member 343 is a spring, and the rotating member 344 is roughly a frame-shaped structure. A through hole (not marked) that is compatible with the inspection fixture 40 is opened inside the rotating member 344, and the inspection fixture 40 is inserted into the through hole. A bolt can be inserted into the end of the rotating member 344 away from the fixing member 341. When fixing the inspection fixture 40, the bolt is tightened so that the bolt abuts against the inspection fixture 40 to complete the fixation.

[0091] Please also see Figure 7 and Figure 8A limiting protrusion 3441 is provided on the side of the rotating member 344 facing the fixed member 341, and a limiting groove 3412 is provided on the side of the fixed member 341 facing the rotating member 344, which is adapted to the limiting protrusion 3441. The limiting protrusion 3441 can be snapped into the limiting groove 3412 to limit the position of the rotating member 344. The limiting protrusion 3441 is generally rectangular in structure, and the limiting groove 3412 is a rectangular structure adapted to the limiting protrusion 3441. In this way, the limiting protrusion 3441 and the limiting groove 3412 cooperate to limit the position of the rotating member 344. After the rotating member 344 is rotated 180 degrees, the limiting protrusion 3441 and the limiting groove 3412 can still limit the position of the rotating member 344.

[0092] See Figure 1 The inspection fixture 40 is connected to the fixed assembly 34 , and detection members 41 are provided at both ends of the inspection fixture 40 . The inspection fixture 40 moves between the two positioning mechanisms 20 under the guidance of the moving mechanism 30 so that the detection members 41 detect the side holes 201 of the workpiece 200 .

[0093] In this embodiment, the side hole 201 is a circular hole, and the detection members 41 are all columnar structures. The radius of one detection member 41 is smaller than the radius of the side hole 201, and the radius of the other detection member 41 is larger than the radius of the side hole 201. During the inspection, if the detection member 41 with a radius smaller than the radius of the side hole 201 can be inserted into the side hole 201, and the detection member 41 with a radius larger than the radius of the side hole 201 cannot be inserted into the side hole 201, it means that the size of the side hole 201 is qualified; if the detection member 41 with a radius smaller than the radius of the side hole 201 cannot be inserted into the side hole 201, it means that the size of the side hole 201 is too small and the side hole 201 is unqualified; if the detection member 41 with a radius larger than the radius of the side hole 201 can be inserted into the side hole 201, it means that the size of the side hole 201 is too large and the side hole 201 is unqualified.

[0094] The detection device 100 provided in the embodiment of the present application can stably support two positioning mechanisms 20 through the support base 10, and can simultaneously position two workpieces 200 through the two positioning mechanisms 20. The moving mechanism 30 can support the inspection fixture 40 and guide the inspection fixture 40 to move between the two workpieces 200. Inspection members 41 are provided at both ends of the inspection fixture 40. Under the guidance of the transverse moving component 31 of the moving mechanism 30, the inspection fixture 40 can move between the two workpieces 200 in the X-axis direction so that the two inspection members 41 can detect the side holes 201 of the two workpieces 200. Under the guidance of the longitudinal moving component 33, the inspection fixture 40 can move in the Y-axis direction, and then move in the X-axis direction through the transverse moving component 31, thereby detecting multiple side holes 201 on the workpiece 200. The above-mentioned detection device 100 can not only stably support the workpiece 200 through the positioning mechanism 20 to reduce the risk of the workpiece 200 falling, but also drive the inspection fixture 40 to move between the two positioning mechanisms 20 carrying the workpiece 200 through the moving mechanism 30, thereby improving the detection efficiency and enhancing the detection accuracy.

[0095] The working process of the detection device 100 provided in the embodiment of the present application is roughly as follows:

[0096] First, open the holding components 23 on the two positioning mechanisms 20, and then place the two workpieces 200 on the positioning blocks 22 on the supporting seats 21 of the two positioning mechanisms 20 respectively, and make the sides of the two workpieces 200 opposite to the moving mechanism 30, and then rotate the pressing claw 234 so that the pressing claw 234 presses the workpiece 200 to complete the positioning of the workpiece 200.

[0097] The operator then moves the second sliding base 332 along the Y-axis, aligning the gauge 40 on the fixed assembly 34 connected to the second sliding base 332 with one of the side holes 201 of the workpiece 200 along the X-axis. The operator then moves the first sliding base 312 along the X-axis, moving one of the inspection members 41 on the gauge 40 toward its corresponding workpiece 200 to inspect the side hole 201 on that workpiece 200. After the inspection is complete, the operator moves the first sliding base 312 in the opposite direction of the X-axis, moving the other inspection member 41 of the gauge 40 toward another workpiece 200 to inspect the side hole 201 of that workpiece 200. After the side holes 201 at the same position on the two workpieces 200 in the X-axis direction are inspected, the second sliding seat 332 is moved along the Y-axis direction and positioned by the positioning beads 333 so that the inspection member 41 of the inspection fixture 40 is opposite to the next side hole 201 on the workpiece 200. Then, the first sliding seat 312 is moved along the X-axis direction, and the above steps are repeated until all the side holes 201 are inspected.

[0098] After all the side holes 201 are inspected, the rotating member 344 is pulled upward and rotated 180° to swap the positions of the two inspection members 41 , and the above inspection process is repeated to inspect the side holes 201 with the replacement inspection members 41 .

[0099] When the height of the gauge 40 needs to be lowered, the adjusting member 322 is tightened. The adjusting member 322 pulls the floating plate 321 closer to the first sliding seat 312. At this time, the floating plate 321 and the first sliding seat 312 compress the second elastic member 323, causing the floating plate 321 to move downward, thereby driving the fixed assembly 34 and the gauge 40 downward to lower the height of the gauge 40. When the height of the gauge 40 needs to be raised, the adjusting member 322 is loosened. The floating plate 321, pushed upward by the second elastic member 323, moves away from the first sliding seat 312. The floating plate 321 drives the fixed assembly 34 and the gauge 40 upward to adjust the height of the gauge 40.
