[0038] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0039] like Figures 1 to 16 As shown, the fixture inspection machine 100 provided in this embodiment of the present invention is used to inspect fixture components. The fixture components include a first fixture (not shown in the figure) having a first group of inspection points and a second fixture 200 (see reference 200) having a second group of inspection points. Figures 14 to 16 The first detection point of the first detection point group and the second detection point of the second detection point group are connected in a one-to-one correspondence. The fixture inspection machine 100 includes a detection frame 1, an inspection platform 2, a fixture drive device 3, a fixture detection device 4, and a card box 5. The inspection platform 2, the fixture drive device 3, and the card box 5 are installed on the detection frame 1. The inspection platform 2 is used to hold the first fixture. The card box 5 is used to hold the second fixture 200. The card box 5 is equipped with a detection module, which is used to electrically connect with each second detection point.

[0040] The output end of the fixture driving device 3 is connected to the fixture detection device 4. The fixture driving device 3 is used to drive the fixture detection device 4 to move along the direction perpendicular to the height of the fixture inspection machine 100. The fixture detection device 4 is electrically connected to the detection module. The fixture detection device 4 is used to position the first fixture on the inspection platform 2. The fixture detection device 4 and the first detection point are provided with a conductive state and a disconnected state.

[0041] The detection module is used to perform conductivity detection on the corresponding first and second detection points when the circuit is on.

[0042] For example, the first detection point group may have multiple first detection points, and the second detection point group may have multiple second detection points. The multiple first detection points and the multiple second detection points can be connected one-to-one by wires.

[0043] Furthermore, for ease of understanding, taking an example where the first detection point group has two first detection points and the second detection point group has two second detection points, let the two first detection points be the first point and the second point, and the two second detection points be the third point and the fourth point. The first point and the third point are connected, and the second point and the fourth point are connected. After placing the first fixture on the inspection platform 2 and the second fixture 200 on the card box 5, the third point and the fourth point are electrically connected to the detection module. When the fixture detection device 4 is connected to the first point, a closed loop will be formed between the fixture detection device 4, the first point, the third point, and the detection module, enabling the detection module to perform electrical conductivity detection on the first point and the third point; when the fixture detection device 4 is connected to the second point, a closed loop will be formed between the fixture detection device 4, the second point, the fourth point, and the detection module, enabling the detection module to perform electrical conductivity detection on the second point and the fourth point.

[0044] For example, when performing conductivity detection, the detection module can detect information such as the continuity state, voltage, current, and resistance between the interconnected first and second detection points.

[0045] The fixture inspection machine 100 provided in this embodiment of the utility model places a second fixture 200 in a card box 5. Each second detection point of the second detection point group of the second fixture 200 is electrically connected to the detection module of the card box 5. A first fixture is placed on an inspection platform 2. When the fixture driving device 3 drives the fixture detection device 4 to approach the first fixture on the inspection platform 2, the fixture detection device 4 can position the first fixture on the inspection platform 2 and make conductive contact with the first detection point of the first detection point group of the first fixture. When the fixture detection device 4 makes conductive contact with the first detection point, the fixture detection device 4 and the first detection point are in a conductive state. At this time, the detection module can perform conductive detection on the corresponding connected first and second detection points. This fixture inspection machine 100 can perform automated inspection of fixture components, improving inspection efficiency.

[0046] In one embodiment, such as Figure 2 and Figure 3As shown, the inspection platform 2 includes an inspection support plate 21, an inspection fixing structure 22, and an inspection limiting structure 23. The inspection support plate 21 is used to place the first fixture. The inspection support plate 21 has a first edge 21a extending along a first direction x and a second edge 21b extending along a second direction y. The first direction x and the second direction y are perpendicular to the height direction of the fixture inspection machine 100. For example, the first direction x is parallel to the length direction of the fixture inspection machine 100, and the second direction y is parallel to the width direction of the fixture inspection machine 100.

[0047] The inspection limiting structure 23 is installed on the first edge 21a and is used to limit the movement of the first fixture relative to the inspection support plate 21 along the second direction y.

[0048] The inspection fixing structure 22 is installed on the second edge 21b and is used to temporarily fix the first fixture to the inspection support plate 21.

[0049] When the first fixture is placed on the inspection support plate 21, it can be slidably placed on the inspection support plate 21 along the second direction y. The movement of the first fixture is limited along the second direction y by the inspection limiting structure 23. When the first fixture abuts against the inspection limiting structure 23, the first fixture is in a preset position. After the first fixture is in the preset position, it can be temporarily fixed to the inspection support plate 21 by the inspection fixing structure 22 to prevent displacement of the first fixture and improve inspection accuracy.

[0050] In one embodiment, such as Figure 2 and Figure 3 As shown, the inspection fixing structure 22 includes a fixing bracket 221 and fixing bolts 222. The fixing bracket 221 includes a first fixing plate 2211 and a second fixing plate 2212 connected to the first fixing plate 2211. The first fixing plate 2211 is installed on the second edge 21b. The second fixing plate 2212 includes a first plate portion 22121, which is located on the side of the first fixing plate 2211 near the center of the inspection support plate 21.

[0051] The screw of the fixing bolt 222 passes through the first plate 22121 and is threadedly connected to the inspection support plate 21. A clamping gap is formed between the first plate 22121 and the inspection support plate 21, and the edge of the first fixture can be clamped in the clamping gap.

[0052] When it is necessary to fix the first fixture, the edge of the first fixture can first be positioned between the first plate portion 22121 and the inspection support plate 21. Then, the screw of the fixing bolt 222 passes through the first plate portion 22121 and is threadedly connected to the inspection support plate 21. By rotating the fixing bolt 222 clockwise or counterclockwise, the distance between the nut of the fixing bolt 222 and the inspection support plate 21 can be adjusted, thereby adjusting the width of the clamping gap between the first plate portion 22121 and the inspection support plate 21, so that the edge of the first fixture can be clamped between the first plate portion 22121 and the inspection support plate 21. At the same time, the screw of the fixing bolt 222 can limit the first fixture in the first direction x.

[0053] In one embodiment, such as Figure 2 and Figure 3 As shown, the second fixing plate 2212 only includes the first plate portion 22121. In this case, the fixing bracket 221 has an "L" shaped structure.

[0054] In an embodiment not shown in the figure, the second fixing plate may further include a second plate portion located on the side of the first fixing plate near the center of the inspection support plate. In this case, the fixing bracket has a "T" shaped structure, and the first fixture can be fixed on both sides of the fixing bracket.

[0055] In one embodiment, such as Figure 2 and Figure 3 As shown, the first plate portion 22121 is provided with a first elongated hole 221211 extending along the first direction x, and the screw of the fixing bolt 222 passes through the first elongated hole 221211 and is threadedly connected to the inspection support plate 21.

[0056] For example, the nut of the fixing bolt 222 is located on the side of the first plate portion 22121 facing away from the inspection support plate 21.

[0057] By setting the first elongated hole 221211, the fixing bolt 222 can move relative to the first elongated hole 221211 along the first direction x to make threaded connections with different positions of the inspection support plate 21, thereby adapting to first fixtures of different lengths.

[0058] In one embodiment, such as Figure 2 and Figure 3 As shown, the inspection limiting structure 23 includes a limiting mounting block 231 and a buffer 232. The limiting mounting block 231 is mounted on the first edge 21a, and the buffer 232 is mounted on the side of the limiting mounting block 231 near the center of the inspection support plate 21. The buffer 232 is used to provide cushioning for the movement of the first fixture along the second direction y.

[0059] When the first fixture is aligned with the inspection support plate 21 along the second direction y and abuts against the inspection limiting structure 23, the buffer 232 can provide a buffer for the first fixture, preventing the first fixture from rigidly contacting the inspection limiting structure 23.

[0060] In one embodiment, such as Figure 2 and Figure 3 As shown, there are two first edges 21a, one of which is equipped with at least one inspection limiting structure 23. Thus, the first fixture can be slidably placed on the inspection support plate 21 along the second direction y from the first edge 21a without the inspection limiting structure 23.

[0061] Two second edges 21b are provided, and each second edge 21b is equipped with at least one inspection fixing structure 22. By installing the inspection fixing structure 22 on each second edge 21b, the two sides of the first fixture can be fixed along the first direction z, thereby improving the stability of the first fixture and thus improving the inspection accuracy.

[0062] In one embodiment, such as Figures 6 to 13 As shown, the fixture inspection device 4 includes a mounting frame 41, a probe structure 42, a first drive assembly 43, a first camera assembly 44, and a fine-tuning assembly 45. The first drive assembly 43 is mounted on the mounting frame 41, and its output end is connected to the probe structure 42. The first drive assembly 43 drives the probe structure 42 to move along a third direction z. The probe structure 42 contacts a first inspection point on the inspection platform 2. The probe structure 42 and the first inspection point are in a connected state and a disconnected state. For example, the third direction z is parallel to the height direction of the fixture inspection machine 100, and the first direction x and the second direction y are perpendicular to the third direction z.

[0063] The fine-tuning component 45 includes a first adjusting plate 451, a second adjusting plate 452, and a first locking structure 453. The first adjusting plate 451 is mounted on the mounting bracket 41. The second adjusting plate 452 is movably connected to the first adjusting plate 451 along a third direction z. A first camera component 44 is mounted on the second adjusting plate 452 and is used to capture and position the first fixture on the inspection platform 2. The first locking structure 453 is mounted on the first adjusting plate 451 and has a first locking state capable of locking the second adjusting plate 452 to the first adjusting plate 451, and a first unlocking state capable of unlocking the second adjusting plate 452 to allow it to slide relative to the first adjusting plate 451.

[0064] For example, when the first locking structure 453 is in the first locking state, it can temporarily fix the second adjusting plate 452 to the first adjusting plate 451 to lock the second adjusting plate 452 to the first adjusting plate 451. At this time, the second adjusting plate 452 will not be able to slide relative to the first adjusting plate 451.

[0065] When the first locking structure 453 is in the first unlocked state, it can release the locking of the second adjustment plate 452, allowing the second adjustment plate 452 to slide relative to the first adjustment plate 451. Thus, by adjusting the position of the second adjustment plate 452 in the third direction z, the position of the first camera component 44 installed on the second adjustment plate 452 can be adjusted.

[0066] The probe structure 42 is driven by the first driving component 43 to move along the third direction z, enabling the probe structure 42 to perform automated inspection of the first fixture. At the same time, the first camera component 44 captures and positions the first fixture to confirm its position and improve inspection accuracy. The fine-tuning component 45 can adjust the distance between the first camera component 44 and the first fixture, thereby adjusting the focal length of the first camera component 44 so that it can capture images more clearly and further improve inspection accuracy.

[0067] In one embodiment, such as Figures 6 to 9 As shown, the first driving component 43 includes a driving structure 431 and a transmission structure 432. The driving structure 431 is mounted on the mounting bracket 41, and the transmission structure 432 is connected between the output end of the driving structure 431 and the probe structure 42. The driving structure 431 is used to drive the probe structure 42 to move along the third direction z through the transmission structure 432.

[0068] By setting a transmission structure 432 between the drive structure 431 and the probe structure 42, the transmission structure 432 transmits the torque at the output end of the drive structure 431 to the probe structure 42, thereby realizing the movement drive of the probe structure 42 in the third direction z.

[0069] In one embodiment, such as Figures 6 to 9 As shown, the transmission structure 432 includes a driving wheel 4321, a driven wheel 4322, a synchronous belt 4323, and a transmission component 4324. The driving wheel 4321 and the driven wheel 4322 are rotatably connected to the mounting frame 41, and the driving wheel 4321 and the driven wheel 4322 are spaced apart along the third direction z. The synchronous belt 4323 is wound around the driving wheel 4321 and the driven wheel 4322.

[0070] The transmission component 4324 is slidably connected to the mounting bracket 41 along the third direction z. One end of the transmission component 4324 is connected to the timing belt 4323, and the other end of the transmission component 4324 is connected to the probe structure 42.

[0071] The output end of the drive structure 431 is connected to the drive wheel 4321, and the drive structure 431 is used to drive the drive wheel 4321 to rotate.

[0072] For example, the drive structure 431 can be a drive motor. In other embodiments not shown in the figures, the drive structure can also be other structures capable of rotary drive, such as a rotary cylinder.

[0073] When the drive structure 431 drives the drive wheel 4321 to rotate, the drive wheel 4321 will drive the timing belt 4323 to move, which in turn will drive the transmission component 4324 connected to the timing belt 4323 to slide relative to the mounting bracket 41 along the third direction z, thereby adjusting the position of the probe structure 42 in the third direction z.

[0074] In other embodiments not shown in the figures, the transmission structure may include a transmission gear, a transmission rack, and a transmission component. The transmission gear is rotatably connected to the mounting frame, the transmission rack is slidably connected to the mounting frame along a third direction, the transmission gear meshes with the transmission rack, and the transmission component is connected to the transmission rack. Simultaneously, the output end of the drive structure is connected to the transmission gear, and the drive structure drives the transmission gear to rotate. When the drive structure drives the transmission gear to rotate, the transmission rack slides relative to the mounting frame along a third direction while meshing with the transmission gear, thereby adjusting the position of the transmission component and probe structure connected to the transmission rack in the third direction.

[0075] In one embodiment, such as Figures 6 to 9 As shown, the transmission structure 432 also includes a mounting shaft 4325 and an anti-detachment limiting member 4326. One end of the mounting shaft 4325 is mounted on the mounting bracket 41, and the driven wheel 4322 is rotatably connected to the mounting shaft 4325. The anti-detachment limiting member 4326 is mounted on the other end of the mounting shaft 4325 and is used to prevent the driven wheel 4322 from detaching from the mounting shaft 4325.

[0076] For example, the anti-detachment limiting member 4326 can be a retaining ring.

[0077] When the driven wheel 4322 is rotatably connected to the mounting shaft 4325, in order to prevent the driven wheel 4322 from slipping off the mounting shaft 4325, an anti-slip limiting member 4326 can be installed at the end of the mounting shaft 4325 away from the mounting bracket 41 to limit the mounting shaft 4325 between the mounting bracket 41 and the anti-slip limiting member 4326, thereby preventing the driven wheel 4322 from detaching from the mounting shaft 4325.

[0078] In one embodiment, such as Figure 7As shown, the transmission component 4324 includes a first connecting plate 43241, a second connecting plate 43242, a first fixed seat 43243, and a second fixed seat 43244. One end of the first connecting plate 43241 is clamped to the timing belt 4323, and the other end of the first connecting plate 43241 is connected to the second connecting plate 43242. The second connecting plate 43242 is slidably connected to the mounting bracket 41 along the third direction z.

[0079] The first fixing seat 43243 is insulatedly connected between the second connecting plate 43242 and the second fixing seat 43244, and the probe structure 42 is installed on the second fixing seat 43244.

[0080] For example, the first fixing seat 43243 is an insulating seat, achieving an insulating connection with the second connecting plate 43242 and the second fixing seat 43244. The second fixing seat 43244 is a conductive seat, achieving a conductive connection with the probe structure 42.

[0081] The transmission component 4324 is composed of a first connecting plate 43241, a second connecting plate 43242, a first fixed seat 43243, and a second fixed seat 43244, so as to transmit the force of the synchronous belt 4323 to the first connecting plate 43241, the second connecting plate 43242, the first fixed seat 43243, and the second fixed seat 43244 in sequence, and finally to the probe structure 42 installed on the second fixed seat 43244, so that the probe structure 42 moves along the third direction z.

[0082] In one embodiment, such as Figure 6 , Figure 7 As shown, the first drive assembly 43 further includes a slide rail 433, a slider 434, and two sliding limit members 435. The slide rail 433 is mounted on the mounting bracket 41, and is located on the side of the driven wheel 4322 away from the driving wheel 4321. The slider 434 is mounted on the transmission member 4324, and slides in cooperation with the slide rail 433 along a third direction z. Exemplarily, the slider 434 is mounted on the second connecting plate 43242.

[0083] Two sliding limiters 435 are installed on the mounting bracket 41, and the two sliding limiters 435 are located on opposite sides of the slide rail 433 along the third direction z. The sliding limiters 435 are used to limit the sliding of the slider 434.

[0084] For example, the sliding limiter 435 is a polyurethane limiting adhesive.

[0085] By setting a sliding rail 433 and a slider 434 that can slide together, and mounting the slide rail 433 on the mounting bracket 41 and the slider 434 on the transmission component 4324, a sliding connection between the transmission component 4324 and the mounting bracket 41 is achieved. At the same time, a sliding limiter 435 is set on each side of the slide rail 433. When the slider 434 abuts against the sliding limiter 435, the second connecting plate 43242 can be slidably limited by the sliding limiter 435 to prevent the slider 434 from disengaging from the slide rail 433.

[0086] In one embodiment, such as Figure 6 As shown, the transmission component 4324 is provided with a first sensing component 46, and the mounting bracket 41 is provided with a first sensor, a second sensor and a third sensor 47 in sequence along the third direction z.

[0087] When the first sensor 46 approaches the first sensor, the first drive assembly 43 stops to limit the transmission member 4324 from continuing upward; when the first sensor 46 approaches the third sensor 47, the first drive assembly 43 stops to limit the transmission member 4324 from continuing downward; when the first sensor 46 approaches the second sensor, the transmission member 4324 returns to the calibrated origin position.

[0088] For example, the first sensing element 46 is a photoelectric sensor, and the first sensor, the second sensor, and the third sensor 47 are photoelectric emitters.

[0089] In one embodiment, such as Figure 7 As shown, the mounting bracket 41 includes a first mounting plate 411 and a second mounting plate 412. The second mounting plate 412 is provided with a mounting groove 4121. The first mounting plate 411 is mounted on the second mounting plate 412, and a portion of the first mounting plate 411 is located within the mounting groove 4121.

[0090] The drive structure 431, the drive wheel 4321 and the driven wheel 4322 are mounted on the first mounting plate 411, the transmission component 4324 is slidably connected to the second mounting plate 412 along the third direction z, and the first adjustment plate 451 is mounted on the second mounting plate 412.

[0091] Mounting bracket 41 has a split structure, which makes it easier to install and connect the various components.

[0092] In one embodiment, such as Figures 6 to 9 As shown, in order to improve the installation stability of the first mounting plate 411 and the second mounting plate 412, the mounting bracket 41 may also include at least one reinforcing plate 413. The reinforcing plate 413 is connected between the first mounting plate 411 and the second mounting plate 412, making the installation of the first mounting plate 411 and the second mounting plate 412 more stable, and also making the installation position of the drive structure 431 more stable.

[0093] In one embodiment, such as Figure 6 , Figure 7 As shown, the mounting bracket 41 also includes a cover 414, which is mounted on the first mounting plate 411, and a receiving space is formed between the cover 414 and the first mounting plate 411. The drive wheel 4321, the driven wheel 4322 and the timing belt 4323 are located in the receiving space.

[0094] By placing the drive wheel 4321, driven wheel 4322, and timing belt 4323 within the accommodating space enclosed by the housing 414 and the first mounting plate 411, the drive wheel 4321, driven wheel 4322, and timing belt 4323 can be shielded, thus protecting them and making the fixture testing device 4 look neater.

[0095] In one embodiment, such as Figure 8 As shown, the fine-tuning component 45 also includes a fine-tuning bracket 454, which is mounted on the second mounting plate 412. The fine-tuning bracket 454 has a groove 4541 on one side facing the second mounting plate 412, and the cover 414 is at least partially located in the groove 4541.

[0096] The first adjustment plate 451 is mounted on the fine-tuning bracket 454.

[0097] When the fine-tuning bracket 454 is installed on the second mounting plate 412, the space occupied by the fixture detection device 4 can be reduced by at least partially embedding the cover 414 into the groove 4541, which is beneficial for the arrangement of a smaller operating space.

[0098] In one embodiment, such as Figures 10 to 13 As shown, the probe structure 42 includes a probe 421, a guide sleeve 422, a guide post 423, an elastic element 424, and a first locking element 425. The guide sleeve 422 has a guide hole 4221 with a first opening 4221a and a second opening 4221b opposite each other along a third direction z. The guide post 423 is movably mounted on the guide sleeve 422 along the third direction z, and at least a portion of the guide post 423 is located within the guide hole 4221. The probe 421 is threaded to the guide post 423 and protrudes from the first opening 4221a.

[0099] The first locking element 425 is threadedly connected to the guide sleeve 422 and can block the second opening 4221b. The elastic element 424 is disposed in the guide hole 4221 and is elastically supported between the first locking element 425 and the guide post 423.

[0100] The output end of the first drive component 43 is connected to the guide sleeve 422.

[0101] For example, the connection between the first locking component 425 and the guide sleeve 422 is a threaded connection. The first locking component 425 can be installed or removed from the guide sleeve 422 by rotating it clockwise or counterclockwise. Further, it can be as follows... Figures 6 to 9 In the illustrated embodiment, an external thread is provided on the outer surface of the first locking fastener 425, and an internal thread is provided on the hole wall of the guide hole 4221. The threaded connection is achieved through the external thread of the first locking fastener 425 and the internal thread of the guide sleeve 422. Alternatively, in other embodiments not shown in the figure, an external thread may also be provided on the outer surface of the guide sleeve, and the first locking fastener may be selected as a cap-type structure with internal threads (similar to a bottle cap with internal threads). The threaded connection is achieved through the external thread of the guide sleeve and the internal thread of the first locking fastener.

[0102] By threading the probe 421 to the guide post 423, the replacement of the probe 421 becomes simpler and faster. Furthermore, since the elastic element 424 is elastically supported between the first locking fastener 425 and the guide post 423, the elastic deformation of the elastic element 424 can buffer the probe 421 during detection. The elastic force of the elastic element 424 can be adjusted by adjusting the first locking fastener 425, effectively reducing wear on the probe 421 and saving replacement costs. In addition, since the first locking fastener 425 can seal the second opening 4221b, it prevents the guide post 423 from slipping out of the guide sleeve 422.

[0103] In one embodiment, such as Figure 11 As shown, the guide hole 4221 has a first limiting part 4221c on its wall and the guide post 423 has a second limiting part 423a. The second limiting part 423a and the first limiting part 4221c are mutually limiting to prevent the guide post 423 from coming out of the first opening 4221a.

[0104] By providing a first limiting part 4221c and a second limiting part 423a on the hole wall of the guide hole 4221 and the guide post 423 respectively, the guide post 423 can be limited by the second limiting part 423a and the first limiting part 4221c to prevent it from falling out of the guide sleeve 422.

[0105] In one embodiment, such as Figure 11 and Figure 12As shown, the guide hole 4221 includes a first hole segment 42211 and a second hole segment 42212 connected along a third direction z. A first opening 4221a is located on the side of the first hole segment 42211 away from the second hole segment 42212, and a second opening 4221b is located on the side of the second hole segment 42212 away from the first hole segment 42211. The cross-sectional area of ​​the first hole segment 42211 is smaller than the cross-sectional area of ​​the second hole segment 42212. A first limiting surface 42213 is formed at the junction of the first hole segment 42211 and the second hole segment 42212. The first limiting part 4221c is formed by the first limiting surface 42213.

[0106] The guide post 423 includes a first post segment 4231 and a second post segment 4232. The second post segment 4232 is disposed within the second hole segment 42212, and the first post segment 4231 is connected to the side of the second post segment 4232 away from the second opening 4221b. The cross-sectional area of ​​the first post segment 4231 is smaller than that of the second post segment 4232, and a second limiting surface 4234 is formed at the junction of the first post segment 4231 and the second post segment 4232. The second limiting part 423a is formed by the second limiting surface 4234.

[0107] The first limiting surface 42213 can abut against the second limiting surface 4234.

[0108] The probe 421 is threaded to the first column segment 4231, and the elastic element 424 is elastically supported between the first locking element 425 and the second column segment 4232.

[0109] By abutting the first limiting surface 42213 and the second limiting surface 4234, the guide sleeve 422 limits the guide post 423, preventing the guide post 423 from coming out of the first opening 4221a and out of the guide sleeve 422.

[0110] In one embodiment, such as Figure 7 and Figure 8 As shown, the guide post 423 also includes a third post segment 4233, which is connected to the side of the second post segment 4232 away from the first post segment 4231. One end of the elastic member 424 is sleeved on the third post segment 4233 and elastically abuts against the second post segment 4232. The other end of the elastic member 424 elastically abuts against the first locking member 425.

[0111] By setting the third column segment 4233, the installation of the elastic element 424 can be limited, preventing the elastic element 424 from moving relative to the guide column 423.

[0112] In one embodiment, such as Figure 11 As shown, part of the guide post 423 is located inside the guide hole 4221, and the rest of the guide post 423 extends out of the guide sleeve 422 through the first opening 4221a.

[0113] At this time, part of the guide post 423 is located inside the guide sleeve 422, and part of it is exposed outside the guide sleeve 422, which facilitates the installation of the probe 421.

[0114] In one embodiment, such as Figure 11 As shown, one end of the first locking fastener 425 is threaded into the guide hole 4221, and the other end of the first locking fastener 425 extends out of the guide sleeve 422 through the second opening 4221b.

[0115] The probe structure 42 also includes a second locking member 426, which is threaded to the outer wall of the first locking member 425 and can abut against the guide sleeve 422.

[0116] By threading a portion of the first locking fastener 425 into the wall of the guide hole 4221, the first locking fastener 425 is connected to the guide sleeve 422. Simultaneously, the first locking fastener 425 can seal the second opening 4221b, preventing the guide post 423 from dislodging from the second opening 4221b and exiting the guide sleeve 422. Furthermore, when the first locking fastener 425 is threaded into the guide sleeve 422, the compression of the elastic element 424 can be adjusted by regulating the length of the threaded connection of the first locking fastener 425 to the guide hole 4221, thereby adjusting the pressure of the probe 421. After the first locking fastener 425 is threadedly connected to the guide sleeve 422, the second locking fastener 426 can be threadedly connected to the outer wall of the portion of the first locking fastener 425 that extends out of the guide sleeve 422 until the second locking fastener 426 abuts against the guide sleeve 422. This further fixes the position of the first locking fastener 425 relative to the guide sleeve 422, reducing the possibility of the first locking fastener 425 undergoing slight displacement relative to the guide sleeve 422 in the third direction z under the action of the elastic member 424.

[0117] Furthermore, since the elastic element 424 is elastically supported in the third direction z between the first locking fastener 425 and the guide post 423, the thread gap between the first locking fastener 425 and the guide sleeve 422 can be eliminated by the elastic element 424.

[0118] In one embodiment, such as Figure 11 As shown, the probe structure 42 also includes a conductive element 427, through which the probe 421 passes and is threadedly connected to the guide post 423.

[0119] By threading the probe 421 through the conductive element 427 and connecting it to the guide post 423, the conductive element 427 is fixed while the probe 421 is being installed.

[0120] In one embodiment, such as Figure 11As shown, a limiting protrusion 4211 is provided on the outer periphery of the probe 421, and the conductive element 427 is clamped between the limiting protrusion 4211 and the guide post 423 along the third direction z.

[0121] By setting a limiting protrusion 4211 on the outer periphery of the probe 421, and enabling the limiting protrusion 4211 and the guide post 423 to clamp the conductive element 427 along the third direction z, the conductive element 427 is fixed and prevented from falling off.

[0122] In one embodiment, such as Figure 8 As shown, the first locking structure 453 includes a first locking plate 4531 and a first locking bolt 4532. The first locking plate 4531 includes a first part 45311 and a second part 45312 connected to the first part 45311. The first part 45311 is mounted on the first adjusting plate 451. The second part 45312 is provided with a second elongated hole 453121 extending in the third direction z. The second adjusting plate 452 is provided with a first locking hole. The screw of the first locking bolt 4532 passes through the second elongated hole 453121 and is threadedly connected to the first locking hole.

[0123] In the first locked state, the second part 45312 is clamped between the nut of the first locking bolt 4532 and the second adjusting plate 452.

[0124] When the first locking bolt 4532 is rotated, the nut of the first locking bolt 4532 and the second part 45312 are brought closer and closer to the second adjusting plate 452 until the nut of the first locking bolt 4532 abuts against the second part 45312 and the second part 45312 abuts against the second adjusting plate 452. At this time, the friction generated when the second part 45312 abuts against the second adjusting plate 452 prevents the second adjusting plate 452 from moving relative to the second part 45312 in the third direction z, thereby restricting the free movement of the second adjusting plate 452 relative to the first adjusting plate 451.

[0125] In one embodiment, such as Figures 6 to 9 As shown, the fine-tuning assembly 45 also includes a fine-tuning bracket 454 and a second locking structure 455. The fine-tuning bracket 454 is mounted on the mounting bracket 41, and the first adjustment plate 451 is mounted on the fine-tuning bracket 454. The second locking structure 455 is mounted on the second adjustment plate 452, and the second locking structure 455 has a second locking state capable of locking the second adjustment plate 452 to the fine-tuning bracket 454, and a second unlocking state capable of unlocking the second adjustment plate 452 to allow the second adjustment plate 452 to move relative to the fine-tuning bracket 454.

[0126] For example, the fine-tuning bracket 454 is mounted on the second mounting plate 412.

[0127] By setting a second locking structure 455, the free movement of the second adjusting plate 452 relative to the first adjusting plate 451 can be further restricted without adjusting the position of the second adjusting plate 452.

[0128] In one embodiment, such as Figures 6 to 9 As shown, the second locking structure 455 includes a second locking plate 4551 and a second locking bolt (not shown). The second locking plate 4551 includes a third part 45511 and a fourth part 45512 connected to the third part 45511. The third part 45511 is mounted on the second adjusting plate 452. The fourth part 45512 is provided with a third elongated hole 455121 extending along the third direction z. The fine-tuning bracket 454 is provided with a second locking hole. The screw of the second locking bolt passes through the third elongated hole 455121 and is threadedly connected to the second locking hole.

[0129] In the second locked state, the fourth part 45512 is clamped between the nut of the second locking bolt and the fine-tuning bracket 454.

[0130] When the second locking bolt is rotated, the nut of the second locking bolt and the fourth part 45512 are brought closer and closer to the fine-tuning bracket 454 until the nut of the second locking bolt abuts against the fourth part 45512, and the fourth part 45512 abuts against the fine-tuning bracket 454. At this time, the friction generated when the fourth part 45512 abuts against the fine-tuning bracket 454 prevents the fourth part 45512 from moving relative to the fine-tuning bracket 454 in the third direction z. This restricts the free movement of the second adjustment plate 452 relative to the fine-tuning bracket 454 and restricts the free movement of the second adjustment plate 452 relative to the first adjustment plate 451.

[0131] In one embodiment, such as Figure 8 As shown, the first camera assembly 44 includes a camera 441, a light source 442, a third mounting base 443, and a locking block 444. The third mounting base 443 is mounted on the second adjustment plate 452, and the locking block 444 is mounted on the third mounting base 443. The locking block 444 cooperates with the third mounting base 443 to clamp the camera 441, and the light source 442 is mounted on the third mounting base 443.

[0132] Camera 441 is used to photograph the first fixture, and light source 442 is used to provide a field of view for camera 441.

[0133] The camera 441 is fixed by the cooperation of the locking block 444 and the third fixing base 443. The light source 442 is installed by mounting it on the third fixing base 443.

[0134] In one embodiment, such as Figure 6 As shown, the third part 45511 can be installed on the third mounting base 443.

[0135] In one embodiment, the fixture inspection machine 100 further includes a controller, which is installed on the inspection frame 1 and is communicatively connected to the fixture drive device 3, the card box 5 and the fixture inspection device 4. The controller is used to record the conduction status of the corresponding connected first inspection point and second inspection point.

[0136] In one embodiment, such as Figure 1 and Figure 5 As shown, the fixture inspection machine 100 also includes a calibration device 6, which includes a second camera component 61 and a height calibration component 62. The second camera component 61 and the height calibration component 62 are mounted on the inspection frame 1, and the second camera component 61 and the height calibration component 62 are respectively connected to the controller.

[0137] The second camera assembly 61 is used to capture and position the probe structure 42 along the third direction z. The height correction assembly 62 is used to abut against the probe structure 42 along the third direction z, and the controller is also used to record the height of the probe structure 42 when it abuts against the height correction assembly 62.

[0138] Specifically, when the probe structure 42 comes into contact with the height correction component 62, the controller can obtain the descent distance of the probe structure 42 and determine the height of the probe structure 42 based on this descent distance. Through the communication connection between the controller and the second camera component 61, the controller can determine the position of the probe structure 42 in the first direction x and the second direction y based on the image captured by the second camera component 61.

[0139] In one embodiment, such as Figure 1 As shown, the fixture driving device 3 includes a second driving component 31 and a third driving component 32. The second driving component 31 is mounted on the testing frame 1, and the output end of the second driving component 31 is connected to the third driving component 32. The second driving component 31 is used to drive the third driving component 32 to move along the second direction y.

[0140] The output of the third drive component 32 is connected to the fixture detection device 4. The third drive component 32 is used to drive the fixture detection device 4 to move along the first direction x.

[0141] By cooperating with the second drive component 31 and the third drive component 32, the position of the fixture detection device 4 in the first direction x and the second direction y can be adjusted so that the fixture detection device 4 can perform spot checks.

[0142] In one embodiment, such as Figures 14 to 16 As shown, the fixture inspection machine 100 also includes a fixture fixing mechanism 7, which is installed in the card box 5 and is used to fix the second fixture 200.

[0143] The fixture fixing mechanism 7 includes a support frame 71, a positioning component, and a plurality of first locking structures 72. The support frame 71 includes a support module 71a, which includes a plurality of support portions 7101 and a plurality of first locking portions 7102. The plurality of support portions 7101 are arranged sequentially at intervals along the fourth direction m, and a first locking portion 7102 is provided between every two adjacent support portions 7101. The support portions 7101 are used to place the second fixture 200, and each first locking portion 7102 is respectively equipped with at least one first locking structure 72. Exemplarily, the fourth direction m is parallel to the second direction y.

[0144] The first locking structure 72 has a third locking state that can lock the second fixtures 200 on two adjacent support portions 7101 to the support frame 71, and a third unlocking state that can avoid the support portions 7101.

[0145] The positioning component is installed on the support frame 71 and is used to limit the second fixture 200 on each support part 7101.

[0146] When each of the first locking structures 72 is in the third locked state, the second jig 200 can be clamped between the adjacent first locking structure 72 and the support portion 7101. When each of the first locking structures 72 is in the third unlocked state, the first locking structure 72 avoids the support portion 7101, allowing the second jig 200 to be placed on the support portion 7101, or allowing the second jig 200 to be removed from the support portion 7101.

[0147] By providing multiple support portions 7101 and multiple first locking portions 7102 in the support module 71a of the support frame 71, multiple second fixtures 200 can be simultaneously supported by the multiple support portions 7101. When placing the second fixture 200 on each support portion 7101, it can be limited by a positioning component to prevent the second fixture 200 from tilting and affecting the accuracy of subsequent testing. When fixing the second fixture 200, each first locking structure 72 can first be moved to the third unlocked state, allowing the multiple second fixtures 200 to be placed on the multiple support portions 7101 respectively. After the multiple second fixtures 200 are placed on the multiple support portions 7101, each first locking structure 72 can be moved to the third locking state to fix the second fixture 200 on each support portion 7101. Since the first locking structure 72 can simultaneously lock the second fixtures 200 on two adjacent support portions 7101, the fixing efficiency of the second fixtures 200 can be improved. Furthermore, since the fixture fixing mechanism 7 can simultaneously fix multiple second fixtures 200, multiple second fixtures 200 can be inspected simultaneously, improving inspection efficiency. At the same time, since the first locking structure 72 can rotate and limit the fixtures on two adjacent support portions 7101, the placement of the fixtures on the corresponding support portions 7101 can be more precise, improving inspection accuracy.

[0148] In one embodiment, such as Figure 15 and Figure 16 As shown, the first locking structure 72 includes a first mounting shaft 721 and a first locking block 722. The first end of the first mounting shaft 721 is mounted to the first locking portion 7102, and the second end of the first mounting shaft 721 is rotatably connected to the first locking block 722. The rotation axis of the first locking block 722 extends along the height direction of the second fixture 200. For example, in... Figures 14 to 16 In the embodiment shown, the third direction z is parallel to the height direction of the second fixture 200. Similarly, the rotation axis of the first locking block 722 is parallel to the third direction z.

[0149] When the first locking block 722 rotates relative to the first mounting shaft 721, the first locking structure 72 can switch between the third locking state and the third unlocking state.

[0150] For example, the first locking block 722 can be rotated manually to switch the state of the first locking structure 72.

[0151] When the first locking structure 72 is required, the first locking block 722 can be rotated relative to the first mounting shaft 721. This fixing method is simple and can improve the fixing efficiency of the second fixture 200.

[0152] In an embodiment not shown in the figure, the first locking block can also be rotated electrically. In this case, the first mounting shaft may not be provided. That is, the first locking structure includes an electric drive structure and a first locking block. The electric drive structure is mounted on the first locking part, and the output end of the electric drive structure is connected to the first locking block. The electric drive structure drives the first locking block to rotate, thereby achieving the state switching of the first locking structure. Schematic, the electric drive structure can be a rotary motor or a rotary cylinder, or other structure capable of rotary drive.

[0153] In one embodiment, such as Figure 15 and Figure 16 As shown, among the two adjacent support parts 7101, one support part 7101 is the first support part 7101a, and the other support part 7101 is the second support part 7101b.

[0154] The first locking block 722 includes a first locking section 7221, a second locking section 7222, and a first connecting section 7223. The first connecting section 7223 is connected between the first locking section 7221 and the second locking section 7222, and the second end of the first mounting shaft 721 is rotatably connected to the first connecting section 7223.

[0155] When the first locking structure 72 is in the third locking state, the first locking segment 7221 can cooperate with the first support portion 7101a to clamp the edge of the second jig 200 on the first support portion 7101a, and the second locking segment 7222 can cooperate with the second support portion 7101b to clamp the edge of the second jig 200 on the second support portion 7101b.

[0156] Therefore, when the first locking structure 72 is in the third locking state, the second fixture 200 on the first support portion 7101a can be fixed by the clamping of the edge of the second fixture 200 on the first support portion 7101a by the first locking segment 7221 and the first support portion 7101a. The second fixture 200 on the second support portion 7101b can be fixed by the clamping of the edge of the second fixture 200 on the second support portion 7101b by the second locking segment 7222. The first locking structure 72 will simultaneously fix two adjacent second fixtures 200.

[0157] In one embodiment, such as Figure 15 and Figure 16 As shown, the positioning component includes a first limiting structure 73. Each first locking part 7102 is equipped with a first limiting structure 73. The first limiting structure 73 is used to rotate and limit the second fixtures 200 on two adjacent support parts 7101, thereby preventing the second fixtures 200 placed on the support parts 7101 from rotating and affecting the subsequent fixing and detection of the second fixtures 200.

[0158] In one embodiment, such as Figure 15 and Figure 16 As shown, the first limiting structure 73 includes limiting members 731. Each first locking part 7102 is equipped with multiple limiting members 731 so that the second fixtures 200 on two adjacent support parts 7101 can be rotated and limited simultaneously by the multiple limiting members 731.

[0159] For example, multiple limiting members 731 mounted on the same first locking part 7102 are spaced apart along the fifth direction n, and the first locking structure 72 is disposed between any two limiting members 731. For example, the fifth direction n is parallel to the first direction x.

[0160] For example, the limiting member 731 is a cylindrical structure. In other embodiments not shown in the figure, the limiting member may also be an elongated structure extending along the fifth direction. When the limiting member is an elongated structure, only one limiting member may be installed on the first locking part.

[0161] In one embodiment, such as Figure 15 and Figure 16As shown, the support module 71a also includes a second locking part 7103 and a third locking part 7104. Multiple support parts 7101 and multiple first locking parts 7102 within the same support module 71a are located between the second locking part 7103 and the third locking part 7104 along the fourth direction m.

[0162] Among the multiple support portions 7101 within the same support module 71a, the two support portions 7101 located at the outermost edges along the fourth direction m are the first edge support portion 7101c and the second edge support portion 7101d, respectively. The second locking portion 7103 is disposed along the fourth direction m on the side of the first edge support portion 7101c away from the second edge support portion 7101d, and the third locking portion 7104 is disposed along the fourth direction m on the side of the second edge support portion 7101d away from the first edge support portion 7101c.

[0163] The fixture fixing mechanism 7 also includes a second locking structure 74 and a third locking structure 75. The second locking structure 74 is mounted on the second locking part 7103 and can lock the second fixture 200 on the first edge support part 7101c. The third locking structure 75 is mounted on the third locking part 7104 and can lock the second fixture 200 on the second edge support part 7101d.

[0164] To prevent the edge of the second fixture 200 located at the outermost edge of the fourth direction m from lifting or slipping off the edge of the support module 71a along the fourth direction m, a second locking part 7103 and a third locking part 7104 can be respectively provided on both sides of the support module 71a along the fourth direction m. A second locking structure 74 is installed on the second locking part 7103, and a third locking structure 75 is installed on the third locking part 7104. The edges of the second fixture 200 at the outermost edges of both sides of the fourth direction m are locked by the second locking structure 74 and the third locking structure 75, so that the fixture fixing mechanism 7 can fix the second fixture 200 at the outermost edges of both sides of the fourth direction m more stably.

[0165] In one embodiment, such as Figure 15 and Figure 16 As shown, the structures of the second locking structure 74 and the third locking structure 75 can be identical to those of the first locking structure 72. Specifically, the second locking structure 74 may include a second mounting shaft and a second locking block. The first end of the second mounting shaft is mounted on the second locking part 7103, and the second end of the second mounting shaft is rotatably connected to the second locking block. The rotation axis of the second locking block extends along the height direction of the second fixture 200.

[0166] By rotating the second locking block relative to the second mounting shaft, the second locking structure 74 can lock the second fixture 200 on the first edge support 7101c; or the second locking structure 74 can avoid the first edge support 7101c, and the second fixture 200 can be placed on or removed from the first edge support 7101c.

[0167] The third locking structure 75 includes a third mounting shaft and a third locking block. The first end of the third mounting shaft is mounted on the third locking part 7104, and the second end of the third mounting shaft is rotatably connected to the third locking block. The rotation axis of the third locking block extends along the height direction of the second fixture 200.

[0168] By rotating the third locking block relative to the third mounting axis, the third locking structure 75 can lock the second fixture 200 on the second edge support 7101d; or the third locking structure 75 can avoid the second edge support 7101d, allowing the second fixture 200 to be placed on or removed from the second edge support 7101d.

[0169] In one embodiment, such as Figure 15 and Figure 16 As shown, the positioning component includes a second limiting structure 76, which is installed on the second locking part 7103. The second limiting structure 76 is used to rotate and limit the second fixture 200 on the first edge support part 7101c, thereby preventing the second fixture 200 placed on the first edge support part 7101c from rotating and affecting the subsequent fixation and detection of the second fixture 200.

[0170] In one embodiment, such as Figure 15 and Figure 16 As shown, the positioning component also includes a third limiting structure 77, which is installed on the third locking part 7104. The third limiting structure 77 is used to rotate and limit the second fixture 200 on the second edge support part 7101d, thereby preventing the second fixture 200 placed on the second edge support part 7101d from rotating and affecting the subsequent fixation and detection of the second fixture 200.

[0171] In one embodiment, such as Figure 15 and Figure 16 As shown, multiple support modules 71a are provided, and the multiple support modules 71a are spaced apart along the fifth direction n. The fourth direction m is perpendicular to the fifth direction n.

[0172] By setting multiple support modules 71a, the fixture fixing mechanism 7 can fix more second fixtures 200 at once, thereby improving the testing efficiency.

[0173] In one embodiment, such as Figure 15 and Figure 16 As shown, the multiple support parts 7101 of the multiple support modules 71a are arranged in a matrix.

[0174] The support frame 71 also includes a limiting module 71b, with a limiting module 71b provided for every two adjacent support modules 71a along the fifth direction n. The limiting module 71b includes a limiting part 7105 provided between two adjacent support parts 7101 along the fifth direction n.

[0175] The positioning component includes a fourth limiting structure 78. Each limiting part 7105 is equipped with a fourth limiting structure 78. The fourth limiting structure 78 is used to rotate and limit the second fixtures 200 on two adjacent support parts 7101 along the fifth direction n, thereby preventing the two adjacent second fixtures 200 from rotating and affecting the subsequent fixing and detection of the second fixtures 200.

[0176] In one embodiment, such as Figure 15 and Figure 16 As shown, the structures of the second limiting structure 76, the third limiting structure 77, and the fourth limiting structure 78 can all be the same as the structure of the first limiting structure 73, that is, the second limiting structure 76, the third limiting structure 77, and the fourth limiting structure 78 can all include limiting elements.

[0177] In one embodiment, such as Figure 15 and Figure 16 As shown, the support portion 7101 is provided with a threaded hole. The fixture fixing mechanism 7 also includes a locking bolt 79, which can pass through the through hole on the second fixture 200 and be threadedly connected to the threaded hole to fix the second fixture 200 on the support frame 71.

[0178] For example, when the support frame 71 is provided with both locking structures (first locking structure 72, second locking structure 74, and third locking structure 75) and threaded holes, the second fixture 200 can be fixed by either the locking structures or by the locking bolts 79.

[0179] In one embodiment, such as Figure 14 As shown, the support frame 71 includes a base plate 711, a support column 712 and a support plate 713. The support column 712 is connected between the base plate 711 and the support plate 713, and the support module 71a is disposed on the support plate 713.

[0180] Therefore, the support frame 71 is composed of a base plate 711, a support column 712 and a support plate 713. In addition to the support module 71a being set on the support plate 713, the limiting module 71b is also set on the support plate 713.

[0181] In one embodiment, such as Figure 4 As shown, the card box 5 includes a box body 51 and a locking structure 52. The detection module is installed inside the box body 51, and the locking structure 52 is installed on the box body 51. The locking structure 52 is used to lock the fixture fixing mechanism 7 onto the box body 51 to fix the fixture fixing mechanism 7.

[0182] In one embodiment, such as Figure 4 As shown, the locking structure 52 includes a first locking plate 521, a locking drive member 522, and a second locking plate 523. The first locking plate 521 and the housing 51 are arranged opposite each other along the third direction z, and a locking space and a placement hole communicating with the locking space are formed between the first locking plate 521 and the housing 51. The fixture fixing mechanism 7 can be placed in the locking space through the placement hole.

[0183] A locking drive 522 is mounted on the housing 51. The output end of the locking drive 522 is connected to the second locking plate 523. The locking drive 522 is used to drive the second locking plate 523 closer to or further away from the placement hole so that the second locking plate 523 can abut against the fixture fixing mechanism 7. For example, the locking drive 522 can be a locking cylinder.

[0184] Therefore, the fixture fixing mechanism 7 can be locked between the first locking plate 521, the housing 51 and the second locking plate 523, so that the position of the second fixture 200 on the fixture fixing mechanism 7 is more stable and the inspection accuracy is improved.

[0185] In one embodiment, such as Figure 2 As shown, the fixture inspection machine 100 also includes a needle-searching pen 8, which is used to inspect the first inspection point.

[0186] When the fixture inspection machine 100 detects an abnormal point (the first detection point and the second detection point are not connected), the fixture inspection machine 100 can be stopped and the abnormal point can be manually checked by using the needle pen 8.

[0187] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
