[0067] See Figure 1 and Figure 2 As shown, Figure 1 This is a structural diagram of an automatic detection device 100 for shaft parts of the present application. Figure 2 for Figure 1 The front view of the automatic detection device for shaft parts shown.

[0068] See also Figure 3As shown, the automatic detection device 100 for shaft parts of the present application is used to detect the workpiece 5. In some embodiments, the workpiece 5 is a shaft workpiece, and its cross-section is circular. The automatic detection device 100 for shaft parts can detect the longitudinal dimension, axial dimension, cylindricity of the workpiece 5, and the position of each dimension relative to the workpiece 5 itself. The automatic detection device 100 for shaft parts of the present application includes a pushing mechanism 1 that can transfer the workpiece 5 to the measuring station C along a first direction F1, and a measuring mechanism 2 provided at the measuring station C. The measuring mechanism 2 includes a first abutment 21, a second abutment 22 and a measurer 23. The first abutment 21 and the second abutment 22 are used to abut the workpiece 5 corresponding to the limit detection. The measurer 23 is provided on one side of the first abutment 21 and is used to obtain the structural parameters of the workpiece 5 located at the measuring station C, such as obtaining information such as the size of the workpiece 5. The second abutting member 22 is disposed opposite and spaced from the first abutting member 21 along the second direction F2, and at least one of the first abutting member 21 and the second abutting member 22 is configured to be adjustable in the second direction F2 based on the longitudinal dimension of the workpiece 5, thereby confining the workpiece 5 between the first abutting member 21 and the second abutting member 22 and securing the workpiece 5 at the measuring station C. It will be understood that when the workpiece 5 is transferred to the measuring station C by the pusher structure extending along the second direction F2, the first abutting member 21 and the second abutting member 22 are correspondingly adjusted and abut against the ends of the workpiece 5 along the second direction F2, thereby confining the workpiece 5. The first direction F1 and the second direction F2 intersect with each other.

[0069] See also Figure 3 As shown, in some embodiments, the first abutment 21 and the second abutment 22 are both configured to have a conical surface from the abutment end abutting against the workpiece 5 toward a direction away from the abutment end. In other words, the first abutment 21 and the second abutment 22 are both configured to be conical, and their tips abut against the two ends of the workpiece 5, thereby reducing the abutment area with the workpiece 5 and avoiding scratches on the workpiece 5. In addition, by abutting against the two ends of the workpiece 5 in a limiting manner, wear on the side of the workpiece 5 is avoided, which affects the size of the workpiece 5.

[0070] See Figure 1-Figure 3As shown, in some embodiments, the automatic detection device 100 for shaft parts of the present application includes a main body, a feeding mechanism 3 and a measuring mechanism 2 arranged on the main body at intervals along the third direction F3. The measuring mechanism 2 also includes a first abutment driving member 24, which is arranged on the main body and is transmission-connected to the first abutment member 21. The first abutment driving member 24 is used to drive the first abutment member 21 to move along the second direction F2. In some embodiments, the measuring mechanism 2 also includes a second abutment driving member 25, which is arranged on the main body and transmission-connected to the second abutment member 22. The second abutment driving member 25 is used to drive the second abutment member 22 to move along the second direction F2. In some embodiments, a first guide member extending along the second direction F2 is provided on the main body, the first abutment member 21 and the second abutment member 22 are spaced along the second direction F2 and are slidably provided on the first guide member, the first abutment driving member 24 drives the first abutment member 21 to move along the second direction F2 on the first guide member, and the second abutment driving member 25 drives the second abutment member 22 to move along the second direction F2 on the first guide member, thereby realizing relative movement between the first abutment member 21 and the second abutment member 22, and then being able to adjust the distance between the first abutment member 21 and the second abutment member 22 to limit the workpiece 5 of different sizes.

[0071] In some embodiments, the first abutment 21 and the second abutment 22 can be arranged on the main body with the aid of a guide rail or other structure extending along the second direction F2, and then the first abutment driving member 24 provided on the main body is used to drive the first abutment 21 to move along the second direction F2, and the second abutment driving member 25 provided on the main body is used to drive the second abutment 22 to move along the second direction F2 to adjust the distance between the first abutment 21 and the second abutment 22.

[0072] In some embodiments, a first detector may be further provided on the measuring mechanism 2. The first detector may be provided at the measuring station C and is used to detect a first presence signal indicating that the workpiece 5 is located at the measuring station C. Upon detecting the presence of the workpiece 5 at the measuring station C, the first detector outputs a first presence signal to the controller. The controller controls the first abutment member 21 and the second abutment member 22 to move relative to each other in the second direction F2 to clamp the workpiece 5. The controller then controls the first driving member 28 to drive the second abutment member 22 to rotate about an axis parallel to the second direction F2, thereby driving the workpiece 5 to rotate about an axis parallel to the second direction F2. The controller also controls the measuring device 23 to perform measurement and controls the second driving member 291 to drive the measuring device 23 to move in the second direction F2 to perform a comprehensive measurement of the workpiece 5.

[0073] In some embodiments, the loading mechanism 3 further includes a fourth detector 372 electrically connected to the controller. The fourth detector 372 is provided at the pushing station B and is used to detect a fourth presence signal indicating that the workpiece 5 is located at the pushing station B. It is understandable that, upon detecting the presence of the workpiece 5 at the pushing station B, the fourth detector 372 outputs a fourth presence signal to the controller, and the controller controls the pushing drive 13 to drive the support 11 to push the workpiece 5 to the measuring station C. In some embodiments, based on the fourth detector 372, the controller can set a preset driving time for the pushing drive 13 to control the support 11 to move a preset distance along the first direction F1, thereby pushing the workpiece 5 a preset distance to the measuring station C. After the pushing drive 13 has driven for the preset time, the first abutment 21 and the second abutment 22 are controlled to clamp the workpiece 5 for measurement.

[0074] See Figure 1 and Figure 3 As shown, the measuring mechanism 2 further includes a first driving member 28, which is connected to the second abutting member 22 to drive the second abutting member 22 to rotate about an axis parallel to the second direction F2. In some embodiments, the first driving member 28 can be configured as a motor, which drives the second abutting member 22 to rotate about an axis parallel to the second direction F2. In other words, the motor drives the second abutting member 22 to rotate about an axis of the workpiece 5 parallel to the second direction F2, thereby driving the workpiece 5 itself to rotate about its axis parallel to the second direction F2, facilitating the measurement device 23 to detect the peripheral wall of the workpiece 5.

[0075] See also Figure 1 and Figure 3 As shown, the measuring mechanism 2 includes a second driving member 291, a first guide rod 292, and a support. The support is disposed on a side of the first abutting member 21 away from the main body along a first direction F1. The support is used to support a measuring instrument 23, with the measuring end of the measuring instrument 23 positioned at the measuring station C. The first guide rod 292 extends along a second direction F2 and is disposed on the support. The measuring instrument 23 is slidably connected to the first guide rod 292 along the second direction F2 and is also connected to the second driving member 291. Driven by the second driving member 291, the measuring instrument 23 moves along the first guide rod 292 along the second direction F2. During movement, the measuring instrument 23 obtains structural parameters of the workpiece 5 along the second direction F2 and, in conjunction with the workpiece 5's own rotation about an axis parallel to the second direction F2, performs a comprehensive inspection of the workpiece 5. In some embodiments, the measuring instrument 23 is configured as a camera, with two cameras provided. The two cameras are spaced apart along a third direction F3 on either side of the workpiece 5 located at the measuring station C along the third direction F3, with both cameras facing the workpiece 5. That is, two measuring devices 23 can be provided, and the two measuring devices 23 are respectively spaced apart along the third direction F3 on both sides of the workpiece 5 located at the measuring station C along the third direction F3, so as to comprehensively measure the workpiece 5.

[0076] In some embodiments, see Figure 1 and Figure 3 As shown, the automatic inspection device 100 for shaft parts also includes a loading mechanism 3, which is used to transfer the workpiece 5 from the loading station A to the pushing station B along the third direction F3. In some embodiments, the workpiece 5 to be inspected is grabbed by a robot to the loading station A, and the loading structure transfers the workpiece 5 located at the loading station A to the pushing station B, and then the pushing mechanism 1 pushes the workpiece 5 located at the pushing station B to the measuring station C.

[0077] See also Figure 4 and Figure 5 As shown, Figure 4 for Figure 3 The schematic diagram of the structure of the pushing mechanism is shown. Figure 5 for Figure 3 Another schematic diagram of the pusher mechanism is shown. The pusher mechanism 1 includes a pusher drive 13 and a support 11 for carrying the workpiece 5 transferred by the loading mechanism 3 to the pusher station B. It can be understood that the pusher drive 13 is connected to the support 11 to drive the support 11 to move in the first direction F1, and the support 11 then transfers the workpiece 5 from the pusher station B to the measurement station C.

[0078] In some embodiments, in conjunction with Figure 6 As shown, Figure 6 for Figure 1 The structural diagram of the feeding mechanism is shown. The feeding mechanism 3 includes two receiving rods 31 extending along the third direction F3 and arranged in sequence. The ends of the two receiving rods 31 that are close to each other are rotatably connected around an axis parallel to the second direction F2. The loading station A is located at the end of the receiving rod 31 that is farther away from the measuring mechanism 2 along the third direction F3 and close to the measuring mechanism 2. The manipulator grabs multiple workpieces 5 and places them on the loading station A, and makes the extension direction of the workpieces 5 parallel to the second direction F2. In some embodiments, the feeding mechanism 3 includes two groups of receiving rods 31 extending along the third direction F3 and arranged in sequence as described above, and one group is spaced apart from the other group along the second direction F2. One end of the workpiece 5 is placed on one group, and the other end of the workpiece 5 is placed on the other group, thereby ensuring the stability of the workpiece 5 moving along the third direction F3 on the feeding assembly. In some embodiments, the spacing between the two groups of receiving rods 31 is adjustable, so that it can be suitable for transporting workpieces 5 of different sizes.

[0079] In some embodiments, the feeding mechanism 3 further includes a second guide member 38 extending along the second direction F2, and two material receiving rods 31 extending along the third direction F3 and spaced apart along the second direction F2. At least one of the two material receiving rods 31 is slidably connected to the second guide member 38 along the second direction F2. In other words, at least one of the two sets of two material receiving rods 31 extending along the third direction F3 and arranged sequentially is slidably connected to the second guide member 38 along the second direction F2, thereby achieving an adjustable distance between the two sets of material receiving rods 31, thereby enabling the transport of workpieces 5 of different sizes. In some embodiments, the second guide member 38 can be configured as a structure such as a guide rail.

[0080] The loading mechanism 3 has a discharge state. When the loading mechanism 3 is in the discharge state, along the first direction F1, the end of the material receiving rod 31 away from the measuring mechanism 2 is higher than the end of the material receiving rod 31 closer to the measuring mechanism 2, that is, the material receiving rod 31 is in an inclined state. It can be understood that the workpiece 5 located at the loading station A can be moved toward the measuring mechanism 2 under the action of gravity. In other words, the robot extends the multiple workpieces 5 along the second direction F2 and places them on the loading station A. Under the action of gravity, the multiple workpieces 5 located at the loading station A are moved from the loading station A to the pushing station. One of the multiple workpieces 5 closer to the measuring mechanism 2 is moved onto the support member 11. The push drive member 13 drives the support member 11 to push the workpiece 5 to the measuring station C, and then the push mechanism 1 transfers it to the measuring station C.

[0081] In some embodiments, continue to refer to Figure 4 and Figure 5 As shown, combined Figure 3 As shown, a recess 12 is provided at one end of the support member 11 close to the workpiece 5, and the recess 12 is located on the pushing station B, and the workpiece 5 located on the pushing station B can be confined in the recess 12, and when the support member 11 moves along the first direction F1, so that the recess 12 and the workpiece 5 on the recess 12 move toward the measuring station C, the side wall of the support member 11 close to the feeding structure protrudes from the plane where the material receiving rod 31 and the workpiece 5 are in contact, blocking the tendency of other workpieces 5 located on the material receiving rod 31 to move along the third direction F3, thereby allowing multiple workpieces 5 on the material receiving rod 31 to be confined on the material receiving rod 31. It can be understood that after the support member 11 transfers the workpiece 5 limited to the recessed portion 12 to the measuring station C, and the first abutment member 21 and the second abutment member 22 clamp the workpiece 5 and complete the measurement, the support member 11 moves along the first direction F1 under the drive of the pushing drive member 13, so that the recessed portion 12 returns to the pushing station B. At this time, the side wall of the support member 11 close to the feeding structure does not protrude from the plane where the receiving rod 31 and the workpiece 5 are in contact. The workpiece 5 located on the receiving rod 31 slides to the recessed portion 12 under the action of gravity, and then is transferred from the pushing station B to the measuring station C by the recessed portion 12.

[0082] See Figure 1 、 Figure 3 and Figure 6 As shown, in some embodiments, the feeding mechanism 3 of the present application can also implement a random inspection function. The feeding mechanism 3 also includes a third driving member 32 and a receiving box 39. The third driving member 32 is connected to the receiving rod 31 of the two receiving rods 31 extending along the third direction F3 and arranged in sequence, which is farther away from the measuring mechanism 2. The receiving box 39 is provided at the end of the receiving rod 31 farther away from the measuring mechanism 2. The feeding mechanism 3 also has a random inspection state, and the receiving box 39 is used to accommodate the workpieces 5 to be inspected for manual random inspection.

[0083] When the feeding mechanism 3 is in the sampling state, the two material receiving rods 31 are set at an angle, and when the feeding mechanism 3 is switched from the discharge state to the sampling state, the connection between the two material receiving rods 31 moves in the direction away from the main body of the automatic detection device 100 for shaft parts, so that the material receiving rod 31 away from the measuring mechanism 2 is in an inclined state, and the end of the material receiving rod 31 close to the measuring mechanism 2 is higher than the end of the material receiving rod 31 away from the measuring mechanism 2, so that the workpiece 5 located on the material receiving rod 31 can slide to the material receiving box 39 under the action of gravity.

[0084] After the sampling inspection is completed, the third driving member 32 can drive the material receiving rod 31 connected thereto to rotate relative to the other material receiving rod 31 connected thereto, thereby restoring the longitudinal directions of the two material receiving rods 31 to a state parallel to each other, that is, returning the feeding mechanism 3 to the unloading state. In other words, the third driving member 32 is used to drive the material receiving rod 31 connected thereto to rotate so as to switch the feeding mechanism 3 between the unloading state and the sampling inspection state, thereby realizing the sampling inspection function of the automatic inspection device 100 for shaft parts of the present application.

[0085] Continue reading Figure 6 As shown, in some embodiments, the present application also has an air-drying function, and the loading mechanism 3 also includes an air outlet member 33 located between the loading station A and the pushing station B, and a fourth driving member 341 connected to the air outlet member 33. The fourth driving member 341 is used to drive the air outlet member 33 to move along the second direction F2, and the air outlet of the air outlet member 33 is set toward the workpiece 5 on the receiving rod 31, so that the air outlet member 33 can move along the second direction F2, and at the same time blow air to the workpiece 5 located on the receiving rod 31 near the air outlet member 33. It can be understood that it can air-dry the workpiece 5 transferred from the loading station A to the pushing station B, that is, the automatic detection device 100 for shaft parts of the present application has the function of air-drying the workpiece 5.

[0086] In some embodiments, the loading mechanism 3 also includes a second guide rod 342 located between the loading station A and the pushing station B and extending along the second direction F2. The air outlet member 33 is arranged on the second guide rod 342 and can move along the second direction F2 on the second guide rod 342 under the drive of the fourth driving member 341.

[0087] like Figure 6 As shown, in some embodiments, the feeding mechanism 3 further includes a first baffle 351 and a fifth driving member 352. The first baffle 351 is located on the side of the material receiving rod 31 close to the measuring mechanism 2 and is connected to the fifth driving member 352. The first baffle 351 is driven by the fifth driving member 352 to move along the first direction F1 so as to protrude from the material receiving rod 31 along the first direction F1, thereby limiting the movement of the workpiece 5 located on the material receiving rod 31 toward the side close to the pushing station B. It is understandable that the provision of the first baffle 351 can control the number of workpieces 5 between the measuring mechanism 2 and the first baffle 351, that is, to prevent an excessive number of workpieces 5 at the measuring mechanism 2 from squeezing the workpieces 5 off the transport track of the material receiving rod 31. Therefore, the first baffle 351 is provided to limit the number of workpieces 5 in the measuring mechanism 2 and ensure the normal operation of the measuring mechanism 2.

[0088] In some embodiments, see Figure 6 As shown, the feeding mechanism 3 further includes a controller and a second detector 36. The second detector 36 is located on the side of the air outlet 33 near the pushing mechanism 1 and is used to detect a second in-position signal indicating that the workpiece 5 is located at the second detection station. It can be understood that the air outlet 33 is located between the return mechanism and the feeding station A. The workpiece 5 at the feeding station A is first dried by the air outlet 33 before sliding to the pushing station B. Along the third direction F3, the second detection station is closer to the pushing station B than to the feeding station A. The second detector 36 is used to detect whether there is a workpiece 5 on the second detection station. In other words, the second detector 36 is used to detect whether the workpiece 5 located on the receiving rod 31 near the end of the pushing mechanism 1 is accumulated on the side of the air outlet member 33 near the pushing structure. If the workpiece 5 located on the receiving rod 31 near the end of the pushing mechanism 1 has been accumulated to the second detection station, the fifth driving member 352 drives the first baffle 351 to move along the first direction F1 until it protrudes from the receiving rod 31 along the first direction F1, so as to limit the movement of the workpiece 5 located on the receiving rod 31 toward the side near the pushing station B, thereby achieving the effect of avoiding the accumulation of workpieces 5 on the receiving rod 31 near the end of the pushing mechanism 1.

[0089] In some embodiments, the feeding mechanism 3 further comprises a third detector 371 arranged on the air outlet piece 33 at a side close to the feeding station A, along a third direction F3, the third detection station is closer to the air outlet piece 33 than the feeding station A. The third detector 371 is configured to detect a third in-position signal of the workpiece 5 at the third detection station and transmit the third in-position signal to the controller. In some embodiments, when the robot puts the workpiece 5 into the feeding station A, the controller controls the first baffle 351 to protrude from the receiving rod 31 along the first direction F1 to limit the workpiece 5, so that part of the workpiece 5 is arranged on the receiving rod 31 and located at a side of the air outlet piece 33 away from the pushing structure, in other words, at the third detection station. The third detector 371 outputs the third in-position signal to the controller, and the controller controls the air outlet piece 33 to blow air to the part of the workpiece 5 to dry the part of the workpiece 5, thereby realizing the function of drying the workpiece 5.

[0090] Referring to Figure 7 as shown, Figure 7 for Figure 1 as shown below. The shaft part automatic detection device 100 further comprises a discharging classification assembly 4 arranged at a side of the measuring mechanism 2 away from the feeding mechanism 3 along a third direction F3. The workpiece 5 is fed from the feeding mechanism 3 to the measuring mechanism 2, and after the measurement of the measuring mechanism 2 is completed, the workpiece 5 is discharged to the discharging classification assembly 4.

[0091] The discharging classification assembly 4 comprises a first discharging piece 41 and a first telescopic piece 42 arranged at an end of the first discharging piece 41 close to the measuring mechanism 2. The discharging classification assembly 4 further comprises a second discharging piece 43 arranged at a side of the first discharging piece 41 along a first direction F1, and a second telescopic piece 44 arranged at an end of the second discharging piece 43 close to the measuring mechanism 2. In some embodiments, the first telescopic piece 42 is configured to receive the workpiece 5 with a structure parameter within a preset value range and discharge the workpiece 5 to the first discharging piece 41. The second telescopic piece 44 is configured to receive the workpiece 5 with a structure parameter outside the preset value range and discharge the workpiece 5 to the second discharging piece 43. It can be understood that the first telescopic piece 42 is electrically connected to the controller. After the measurement of the measurer 23 is completed, the workpiece 5 data detected by the measurer 23 is transmitted to the controller. The controller determines whether the workpiece 5 is qualified. The workpiece 5 with a structure parameter within the preset value range is qualified, and the workpiece 5 with a structure parameter not within the preset value range is unqualified. After the controller determines that the workpiece 5 is qualified, the first telescopic piece 42 is controlled to extend to receive the qualified workpiece 5. If the controller determines that the workpiece 5 is unqualified, the second telescopic piece 44 is controlled to extend to receive the unqualified workpiece 5.

[0092] In some embodiments, when the measuring device 23 has completed the detection and the workpiece 5 needs to be moved to the corresponding first telescopic member 42 or the second telescopic member 44, the support member 11 of the pushing mechanism 1 can be used to support the workpiece 5, and the pushing drive member 13 can drive the support member 11 to move along the first direction F1 toward the pushing station B, that is, the support member 11 and the workpiece 5 are lowered together along the first direction F1, and at the same time, the corresponding first telescopic member 42 or the second telescopic member 44 extends to catch the workpiece 5, and the support member 11 continues to descend back to the pushing station B, thereby realizing the transfer of the workpiece 5 to the first telescopic member 42 or the second telescopic member 44, and preventing the workpiece 5 from falling directly from the measuring station C to the first telescopic member 42 or the second telescopic member 44, causing damage to the workpiece 5.

[0093] In some embodiments, when the measuring device 23 measures the workpiece 5, the support member 11 that pushes the workpiece 5 to the measuring station C can be controlled to move a preset distance along the first direction F1 toward the direction away from the measuring station C to avoid the support member 11 blocking the side of the workpiece 5, which is not conducive to the measurement of the measuring device 23. After the measurement is completed, the support member 11 is controlled to move along the first direction F1 toward the measuring station C to the measuring station C to receive the workpiece 5, and the workpiece 5 is transferred to the first telescopic member 42 or the second telescopic member 44, wherein the preset distance is less than or equal to the distance from the measuring station C to the pushing station B.

[0094] See Figure 7 As shown, the blanking and sorting assembly 4 further includes a sixth driving member 451 and a seventh driving member 452. The sixth driving member 451 is connected to the first telescopic member 42 to drive the first telescopic member 42 to move along the third direction F3, that is, the sixth driving member 451 is used to drive the first telescopic member 42 to extend or retract along the third direction F3 to receive the workpiece 5 located at the measuring station C and whose structural parameters are within the preset numerical range. The seventh driving member 452 is connected to the second telescopic member 44 to drive the second telescopic member 44 to move along the third direction F3, that is, the seventh driving member 452 is used to drive the second telescopic member 44 to extend or retract along the third direction F3 to receive the workpiece 5 located at the measuring station C and whose structural parameters are outside the preset numerical range.

[0095] In some embodiments, continue to refer to Figure 7As shown, the blanking and sorting component 4 also includes a first guide plate 421 and a second guide plate 441 which are arranged on the measuring mechanism 2 away from the loading mechanism 3 and are spaced apart along the first direction F1. The first guide plate 421 extends along the third direction F3. In some embodiments, the first guide plate 421 is arranged on the main body through a plurality of first columns arranged around the first guide plate 421. The sixth driving member 451 is arranged on the first guide plate 421, and the output end is connected to the first telescopic member 42. It can be understood that the first telescopic member 42 is arranged at one end of the first guide plate 421 close to the measuring mechanism 2, and moves and telescopes along the third direction F3 under the drive of the sixth driving member 451. The second guide plate 441 is closer to the main body relative to the first guide plate 421. In some embodiments, the second guide plate 441 is provided on the main body through a plurality of second columns provided around the second guide plate 441. The seventh driving member 452 is provided on the second guide plate 441, and the output end is connected to the second telescopic member 44. It can be understood that the second telescopic member 44 is provided at one end of the second guide plate 441 close to the measuring mechanism 2, and moves and telescopes along the third direction F3 under the drive of the seventh driving member 452.

[0096] like Figure 7 As shown, the blanking and sorting assembly 4 further includes a first guide rail 461 and a second guide rail 462, which are spaced apart along the third direction F3 and both extend along the second direction F2. The first blanking member 41 includes two first blanking rods 411 spaced apart along the second direction F2, and the first blanking rods 411 are tilted along the third direction F3. In other words, along the first direction F1, the end of the first blanking rod 411 closer to the measuring mechanism 2 is higher than the end of the first blanking rod 411 farther from the measuring mechanism 2. It can be understood that, under the support of the first telescopic member 42, the qualified workpiece 5 moves to the two first blanking rods 411 of the first blanking member 41, with one end of the workpiece 5 being located on one of the two first blanking rods 411 and the other end of the workpiece 5 being located on the other of the two first blanking rods 411. The workpiece 5 then slides down to the end farther from the measuring mechanism 2 under the action of gravity.

[0097] In some embodiments, as Figure 7 As shown, at least one of the two first feeder rods 411 is slidably connected to the first guide rail 461 and the second guide rail 462 along the second direction F2. In other words, one of the two first feeder rods 411 can be mounted on the first guide rail 461 and the second guide rail 462 via a structure such as a slider, so that it can slide along the first guide rail 461 and the second guide rail 462 along the second direction F2. Alternatively, both first feeder rods 411 can slide along the first guide rail 461 and the second guide rail 462 along the second direction F2, thereby adjusting the distance between the two first feeder rods 411 using the first guide rail 461 and the second guide rail 462, thereby accommodating the transport of workpieces 5 of different sizes.

[0098] In some embodiments, see Figure 7 As shown, the second blanking piece 43 includes two second blanking rods 431 spaced apart along the second direction F2, and at least one of the two second blanking rods 431 is slidably connected to the first guide rail 461 and the second guide rail 462 along the second direction F2, so that the distance between the two second blanking rods 431 is adjustable, and thus can be suitable for the transportation of workpieces 5 of different sizes. In some embodiments, one of the two first feed rods 411 and one of the two second feed rods 431 are fixed to each other and are jointly provided on the first guide rail 461 and the second guide rail 462. The other of the two first feed rods 411 and the other of the two second feed rods 431 are fixed to each other. In some embodiments, the other of the two first feed rods 411 and the other of the two second feed rods 431 are jointly provided on the first guide rail 461 and the second guide rail 462. Thus, while adjusting the distance between the two first feed rods 411, the distance between the two second feed rods 431 is also adjusted relative to each other, thereby being suitable for the classified feeding of workpieces 5 of the same size. In some embodiments, a driving member such as a motor or a cylinder is provided on at least one of the two second feed rods 431 to drive the second feed rod 431 to move along the first guide rail 461, the second guide rail 462, and the second guide rail 462 in the second direction F2.

[0099] like Figure 7 As shown, in some embodiments, the blanking and sorting assembly 4 further includes an eighth driving member 471, and the first telescopic member 42 is slidably connected to the first guide rail 461 along the second direction F2, and is driven by the eighth driving member 471 to move along the second direction F2 on the first guide rail 461, thereby adjusting the position of the first telescopic member 42 in the second direction F2. It is understandable that the first telescopic member 42 is provided on the first guide rail 461 by means of the first guide plate 421 and the first column, and the eighth driving member 471 is provided on the main body and is connected to the first telescopic member 42 through the first guide plate 421 and the first column to drive the first telescopic member 42 to move along the second direction F2. The first telescopic member 42 can move along the second direction F2, and the distance between the two first blanking rods 411 can be adjusted, so that the first blanking member 41 and the first telescopic member 42 can adapt to the blanking requirements of workpieces 5 of different sizes.

[0100] In some embodiments, the blanking and sorting assembly 4 further includes a ninth driving member 472, the second telescopic member 44 is slidably connected to the second guide rail 462 along the second direction F2, and is driven by the ninth driving member 472 to move along the second direction F2 on the second guide rail 462, thereby adjusting the position of the second telescopic member 44 in the second direction F2. It is understandable that the second telescopic member 44 is provided on the second guide rail 462 by means of the second guide plate 441 and the second column, and the ninth driving member 472 is provided on the main body, and is connected to the second telescopic member 44 through the second guide plate 441 and the second column to drive the second telescopic member 44 to move along the second direction F2. The second telescopic member 44 can move along the second direction F2, and the distance between the two second blanking rods 431 can be adjusted, so that the second blanking member 43 and the second telescopic member 44 can adapt to the blanking requirements of workpieces 5 of different sizes.

[0101] In some embodiments, see Figure 1 and Figure 2 As shown, the blanking and sorting assembly 4 further includes a blanking chute 432, which is disposed on a side of the main body facing away from the blanking and sorting assembly 4 and at an end of the second blanking member 43 away from the measuring mechanism 2. The notch of the blanking chute 432 faces the end of the second blanking member 43 away from the measuring mechanism 2, so as to be able to receive the workpiece 5 that is blanked into the second blanking member 43 and moves from the end of the second blanking member 43 close to the measuring mechanism 2 to the end of the second blanking member 43 away from the measuring mechanism 2. In other words, the blanking chute 432 can be used to receive unqualified workpieces 5 blanked by the second blanking member 43. The bottom wall of the blanking chute 432 is inclined along the second direction F2, with one end of the bottom wall being higher than the other end along the second direction F2. The side wall of the lower end of the bottom wall of the blanking chute 432 is provided with an opening, so that the workpiece 5 blanked into the blanking chute 432 can slide out through the opening along the bottom wall.

[0102] Continue reading Figure 7 As shown, in some embodiments, the blanking classification component 4 also includes a second baffle 491 and a tenth driving member 492. The second baffle 491 is arranged at one end of the first blanking member 41 away from the measuring mechanism 2, and is used to limit the workpiece 5 on the first blanking member 41 to prevent the workpiece 5 on the first blanking member 41 from sliding out of the first blanking member 41 under the action of gravity. The tenth driving member 492 is used to drive the second baffle 491 to lift or lower, thereby realizing the limitation of the workpiece 5 on the first blanking member 41.

[0103] In some embodiments, the blanking and sorting assembly 4 further includes a fifth detector 481 and a sixth detector 482. The fifth detector 481 is provided at one end of the first blanking member 41 close to the measuring mechanism 2, and the sixth detector 482 is provided at the other end of the first blanking member 41 along the third direction F3, spaced apart from the fifth detector 481. It is understood that, under the limiting action of the second baffle 491, the fifth detector can be used to detect whether the workpieces 5 on the first blanking member 41 have accumulated to the end of the first blanking member 41 close to the measuring mechanism 2. In other words, the fifth detector can be used to detect whether the first blanking member 41 is full of workpieces, thereby transmitting a full-material signal to the controller. In some embodiments, the fifth detector can be combined with an alarm or other structure to issue a full-material reminder to facilitate manual material removal.

[0104] In some embodiments, the sixth detector 482 can be configured to send a signal to the controller when it fails to detect the workpiece 5 for a long time. That is, when the workpiece 5 detection is unqualified for a long period of time, the sixth detector 482 cannot detect the workpiece 5, thereby reminding the staff to perform manual inspection to avoid accidental detection errors of the machine.

[0105] In some embodiments, see Figure 8 As shown, the automatic detection device 100 for shaft parts is arranged in a cabinet 6. The cabinet 6 is provided with a loading port 61 on the top wall facing the loading station A. The manipulator extends into the cabinet 6 from the loading port 61 and places the workpiece 5 on the loading station A. The cabinet 6 is also provided with a cabinet door. When the cabinet door is opened, the loading mechanism 3, the measuring mechanism 2 and the unloading classification component 4 are exposed to facilitate maintenance. The arrangement of the cabinet 6 is convenient for preventing dust and falling dust, and is convenient for safety protection. In some embodiments, sound insulation material can also be provided on the inner wall of the cabinet 6 to reduce noise. In some embodiments, the receiving box 39 is exposed outside the cabinet 6, which is convenient for picking up the workpiece 5 in the receiving box 39 during random inspection.

[0106] The automatic inspection device 100 for shaft parts provided by the present application is used to air-dry the workpiece 5 after it is loaded onto the loading station A. The workpiece 5 is then moved from the loading station A to the pushing station B through the air outlet 33. After air-drying, the workpiece 5 enters the measuring mechanism 2 for measurement. The measuring mechanism 2 abuts against both ends of the workpiece 5 through the first abutment 21 and the second abutment 22 to avoid wear on the surface of the workpiece 5 during measurement. The second abutment 22 is configured to rotate around an axis parallel to the second direction F2, thereby driving the workpiece 5 to rotate along the axis parallel to the second direction F2, making it easier for the measuring device 23 to fully measure the workpiece 5. After the measurement is completed, the controller determines whether the workpiece 5 is qualified, and combines the unloading classification component 4 to separate qualified and unqualified workpieces 5, that is, to pick out unqualified workpieces 5.

[0107] The application can be applied to detection of workpieces 5 of different sizes. The distance between the material receiving rods 31 arranged at intervals in the second direction F2 of the application can be adjusted, the distance between the first abutting member 21 and the second abutting member 22 in the second direction F2 can be adjusted, the distance between the two first material discharging rods 411 in the second direction F2 can be adjusted, the distance between the two second material discharging rods 431 in the second direction F2 can be adjusted, and the first telescopic member 42 and the second telescopic member 44 are both arranged to be movable in the second direction F2. It can be understood that through the above arrangement, the feeding, measuring and discharging classification of workpieces 5 of different sizes can be realized, that is, the application can be applied to workpieces 5 of different longitudinal sizes.

[0108] The application also has the function of sampling inspection. By controlling the third driving member 32 to drive the two material receiving rods 31 extending in the third direction F3 and arranged in sequence to rotate relative to each other, the feeding mechanism 3 can be switched from the feeding state to the sampling inspection state, that is, the two material receiving rods 31 are arranged at an angle, and part of the workpieces 5 slide from the material receiving rod 31 away from the measuring mechanism 2 to the material receiving box 39 for manual sampling inspection.

[0109] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0110] The above-described embodiments only express several implementation manners of the application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the application, several modifications and improvements can be made, which are all within the protection scope of the application. Therefore, the protection scope of the patent of the application should be subject to the appended claims.
