However, after the actual use, it is found that when the camera 13 captures the internal thread image of the object 2, it is difficult to capture the internal thread image by 360 degrees due to the limitation of the illumination angle of the camera 13, so when the camera 13 is unable to shoot It is impossible to know whether there is a 3 M421165 该 at the thread inside, so it is easy to cause inaccuracy in detection, and it needs to be improved. [New content] Therefore, the object of the present invention is to provide a screening machine for detecting the thread in an object, which can quickly and accurately screen whether the internal thread of the object is abnormal, so as to improve the overall efficiency of the screening. Therefore, the screening device for detecting the internal thread of the object is characterized in that the detecting device has a supporting rod, a detecting group disposed opposite to the placing groove, and a driving device for moving the detecting group to the object. And an elastic member for driving the detecting group to return to the home position; wherein the detecting group has a detecting tooth gauge corresponding to the internal thread of the object, and a servo motor for interlocking the detecting tooth gauge into the internal thread of the object; During the detection, the servo motor generates a torque value when the internal thread is screwed into the internal thread, and the torque value is mutually compared with the standard torque value through the transporting device to determine whether the internal thread of the object is abnormal, so It can effectively improve the detection speed and accuracy of the screening machine. The above and other technical contents, features and effects of the present invention will be clearly understood from the following detailed description of the preferred embodiments with reference to the drawings. In the following description, similar elements are denoted by the same reference numerals. Referring to FIG. 2, a preferred embodiment of the present invention, the screening machine 3 for detecting the internal thread of the object 4 includes a feeding device 31' for outputting the entire object 4 to be tested, and a turntable 32 having a plurality of positioning grooves 321 a detecting device 33 disposed adjacent to the 4 M421165 turntable 32 and capable of detecting the object 4, an arithmetic device 34 coupled to the detecting device 33, and a computing device 34 coupled thereto and mounted on the turntable 32 And returning the object 4 to the returning device 35 for returning the material; wherein each of the objects 4 has at least one internal thread, and each of the objects 4 falls into the placing groove 321 for the turntable 32, receiving and carrying, and finally, the material returning device 35 performs sorting of good and bad products for the objects 4 according to the comparison result of the computing device 34; in addition, the computing device 34 has a connection and a sense The control stomach 341 for detecting the torque value required for the operation of the device 33, a storage unit 342 storing the standard required torque value, and a processing unit for comparing the torque value obtained by the controller 341 with the torque value of the storage unit 342 343, and the foregoing processing unit 343 After the comparison, a result signal will be generated. Continuing with the foregoing, with reference to FIG. 3, the detecting device 33 has a supporting rod 331, and a detecting group 332 disposed above the receiving groove 321 to drive the detecting group 332 to the placing slot. The actuator 333 (such as a pneumatic cylinder and an elastic member 334 that drives the detecting group 332 to return to the return position; the detecting group 332 has a detecting tooth gauge 3321 corresponding to the internal thread of the object 4, And a servo motor 3322 that is coupled to the internal thread by a twisting force, and the servo motor 3322 is electrically connected to the computing device 34, that is, when the servo motor 3322 is operated, it will be returned. A torque value is added to the controller 341. In addition, in the embodiment, the support rod 331 is pivotally provided with a movable seat 36 that can slide up and down, and the support rod 331 can be fixed by the actuator 333. The movable seat 36 can be fixed by the servo motor 3322, and at the same time, the 5 M421165 media shields the actuator 333 to be more stable. The movable seat 36 can be disposed on the movable seat 36 and at a time relative to the actuator 333. a top block 361 and the top block 361 is formed with Slotted so that the actuator 333 can partially extend into the opening 3611 and top the movable seat so that the actuator 333 does not disengage from the slot 3611 when the mobile seat 36 is pushed up. Furthermore, the elastic member 334 can be disposed between the actuator 333 and the movable seat 36, or the elastic member 334 can be disposed on the movable seat and the ground (or the bottom surface of the support rod 331) (as shown in FIG. 4). In this embodiment, the elastic member 334 is disposed between the actuator 333 and the moving base. For example, referring to FIG. 2, FIG. 5, and FIG. 6, the feeding device 31 sequentially outputs the object. 4 is disposed on the placement slot 321 of the turntable 32, and is transported to the detecting device 33 via the turntable 32. At this time, the movable block 36 is moved by the actuator and the top push block 361 is pushed. After the moving seat 36 slides on the support rod 331, the detecting tooth gauge 332 is urged toward the surface of the object 4 (ie, as shown in FIG. 5), and the detecting tooth gauge is driven by the servo motor 3322. 3321 is rotated, and the detecting tooth gauge 3321 is gradually locked in the internal thread (ie, as shown by the arrow in FIG. 6) The locking force can make the moving seat 36 off the top of the actuator 333, but because of the setting of the top block 361, the actuator 333 is still limited by the top block. In the slot 3611 of the 361, when the moving seat 36 moves and slides, the balance force can be better, and the detecting tooth gauge 3321 is more stable when the internal thread is locked. · Referring to FIG. 7, the detecting tooth When the gauge 3321 is screwed into the internal thread, the controller 341 can know that the servo motor 3322 drives the torque value required for the M421165 to detect the tooth gauge 3321, so that the processing unit 343 will The lock torque value is compared with the range of the torque value required by the standard of the storage unit 342. If the lock torque value exceeds the standard torque value range, the object 4 is judged to be a defective product, and if the lock torque value is dropped Within the range of the standard torque value, the object 4 is judged to be good, so as to generate a result signal 'and transmit the result signal to the returning device 35, so that the returning device 35 can take the object according to the result signal. 4 Sorting and collecting. Continuing the foregoing, with reference to FIG. 8, when the detecting tooth gauge 3321 is retracted from the internal thread of the object 4, the restoring force of the elastic member 334 can pull the moving seat 36 to move toward the actuator 333 ( That is, as indicated by the arrow, so that the top block 361 can be restored to the top state of the actuator 333, so that the action is repeated to complete the screening operation of the object 4; The consistent detection operation, such as input, detection, and output of the object 4, is smoother, and the detection tooth gauge 3321 can be stably locked into the internal thread of the object 4, so that the object 4 can be completely The internal thread performs the detecting action, and in addition to solving the conventional problem of photographic dead angle, the torque value generated by the detecting tooth gauge 3321 screwing into the internal thread is further utilized, and the torque value is further compared with the standard torque value through the computing device 34. 'By determining whether the internal thread of the object 4 is abnormal, so as to improve the speed and accuracy of the screening machine 3 screening. Referring to FIG. 9 and the second preferred embodiment of the present invention, a screening machine 3 for detecting internal threads of an object 4 further includes a feeding device 31, a turntable 32, a detecting device 33, an arithmetic device 34, a stripping device 35, and the like. The connection relationship, the action, and the effect to be achieved by the foregoing structure 7 M421165 are the same as those of the first embodiment, and therefore are not described in detail; in particular, the implementation of the turntable 32 is further provided with a top set 335. The top set 335 can lie on the object 4 on the placing groove 321 so that the object 4 can be stably placed on the placing groove 321 to make the detecting group 332 more accurate. In summary, the present invention is a screening machine for detecting the internal thread of an object, which mainly uses the detecting tooth to generate a torque value when the internal thread is rotated, and the torque value is mutually compared with the standard torque value through the computing device. 'According to the accurate and rapid judgment of whether the internal thread of the object is abnormal, to improve the screening accuracy of the screening machine.
