Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
1-6, The screw inspection device comprises a base 1, a vibrator 2, an induction mechanism 3 and a conduction mechanism 4, wherein the vibrator is arranged in the base 1, and the conduction mechanism 4 is obliquely arranged on the base 1; typically, the angle between the conducting means 4 and the horizontal is 60-75 °; preferably, the angle between the conducting means 4 and the horizontal plane is 65 °. Moving the screw from one end of the conduction mechanism 4 to the other end by shaking the vibrator 2; the conduction mechanism 4 includes a front plate 41, a rear plate 42, a connection block 43, an adjustment block 44, and a first fixing mechanism 45, the front plate 41 and the rear plate 42 are rectangular parallelepiped bar-shaped structures, and the front plate 41 and the rear plate 42 are arranged in parallel through the connection block 43, forming a guide groove for transmitting screws. The back plate 42 is provided with a first opening 421 and a second opening 422, the front plate 41 is provided with a third opening 411 and a fourth opening 412, the positions of the first opening 421 and the third opening 411 correspond to each other, the sensing mechanism 3 is arranged at the positions of the first opening 421 and the third opening 411, and when the sensing mechanism senses a screw, the screw is excessively long, and the device is stopped and warned through the PLC control equipment. Thereby realizing the overlong detection of the screw. The adjusting block 44 is slidably disposed in the second opening 422 to adjust the size of the second opening 422, and the adjusting block 44 is fixed at a designated position by the first fixing mechanism 45. The shortest length of the screw is selected according to the screw standard, i.e. the standard screw minus the screw allows Xu Changdu errors. When the screw passes through the second opening 422, if the screw meets the standard, one end of the screw is placed on the adjusting block 44, and if the screw is shorter and does not meet the standard, the end of the screw cannot be placed on the adjusting block 44, and the screw falls from the fourth opening 412 of the second opening 412 by utilizing the weight of the screw, so that the too short detection of the screw is realized.
In an embodiment, as shown in fig. 1 to 8, the side walls on two sides of the second opening 422 are provided with a first sliding groove 4221, two sides of the adjusting block 44 are slidably arranged in the first sliding groove 4221, the first fixing mechanism 45 comprises a first screw 451 and a first spring 452, a first screw hole 4222 matched with the first screw 451 is arranged in the first sliding groove 4221, and the first screw 451 passes through the adjusting block 44 and the first spring 452 to be connected with the first screw hole 422. The first spring 452 enables the adjusting block 44 to be always clung to the first screw 451, and then the distance from the adjusting block 44 to the bottom of the second opening 422 is changed by rotating the first screw 451. When the screw passes the time, one end of the screw is turned downward due to its own weight, and then falls down from the second opening 422.
In an embodiment, as shown in fig. 1-8, the device further comprises a supporting block 47 and a second fixing mechanism 48, wherein the side walls at two sides of the first opening 421 are provided with second sliding grooves 4211, two sides of the supporting block 48 are slidably arranged in the second sliding grooves 4211, and the supporting block 47 is fixed at a specified position by using the second fixing mechanism 48. By adjusting the position of the supporting block 47 in the first opening 421, the detection range is increased; according to the screws of different lengths, the position of the supporting block 47 is adjusted so that the screws cannot fall down due to the overturning of the screws by the weight of the screws. Specifically, the second fixing mechanism 48 includes a second screw 481 and a second spring 482, a second screw hole 4212 matching the second screw 481 is provided in the second sliding groove 4211, and the second screw 481 passes through the support block 47 and the second spring 482 and is connected to the second screw hole 4212. The position of the support block 47 within the first opening 421 is adjusted by turning the second screw 481.
In an embodiment, as shown in fig. 1-8, the connecting block 43 is in a U-shaped structure, one side wall of the connecting block is fixedly connected with the rear plate 42, a guide hole 431 and a locking screw hole 432 are arranged on the other side wall of the connecting block, an adjusting screw hole 413 is arranged on the front plate 41, the adjusting screw hole 413 corresponds to the guide hole 431, when in use, the adjusting screw 414 penetrates through the guide hole 431 to be connected with the adjusting screw hole 413, the adjusting screw 414 is tightly attached to the connecting block by utilizing the self weight of the front plate 41, the locking screw 433 is matched with the locking screw hole 432, and the end part of the locking screw 433 abuts against the front plate 41 by rotating the locking screw 433, so that the front plate 41 and the connecting block 43 are fixed. Through the above structure, the distance between the front plate 41 and the rear plate 42 can be adjusted, and the detection range is further wider. Since the adjusting screw 414 cannot pass through the adjusting screw hole 413, normal passing of the detecting screw is affected; however, since the length of the adjusting screw hole 413 is limited, the thickness adjusting range of the guide groove is small; preferably, the guide groove adjusting device further comprises a gasket, wherein the gasket is sleeved on the adjusting screw 414, and the adjusting range of the guide groove is further increased.
In an embodiment, as shown in fig. 1-9, the sensing mechanism 3 includes a fixed block 31, a U-shaped bracket 32, a laser sensor 33 and a fixed screw 34, where the fixed block 431 is disposed on one side of the base 1 and is disposed in a gap with the base 1, so as to prevent the shake of the vibrator 3 from driving the sensing mechanism 3 to shake, which results in a large error of the detection result. The fixed block 31 is vertically provided with a guide hole, the bottom of the U-shaped bracket 32 is arranged in the guide hole in a sliding way, and the U-shaped bracket 32 is fixedly connected with the fixed block 31 through a fixed screw 34; the laser sensor 33 is arranged on the U-shaped bracket 32, and the laser sensor 33 typically comprises a transmitter and a receiver, and is thus arranged on both side walls of the U-shaped bracket 32. The U-shaped bracket 32 is matched with the fixed block 31, so that the height position of the laser sensor 33 is adjusted to be matched with different detection screws.
In use, as shown in fig. 1-9, the screws are sequenced by the vibrating disk, entering from the inlet end of the conduction mechanism 4, and vibrated by the vibrator 2 so that the screws move from the inlet end to the outlet end of the conduction mechanism 4. Firstly, the screw is detected longer, if the screw is detected longer, when the screw passes through the sensing mechanism 3, the screw shields the laser sensor 33, signals are sent to the PLC, and then the machine is stopped, and the machine waits for the staff to take out. And after the screw is qualified, the screw is continuously moved to the second opening 422 to perform the screw too short detection, and if the screw is too short, the screw automatically falls from the second opening 422. The detection of the screw length is realized through the structure. The inspection efficiency and reliability are improved.
The foregoing is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention; modifications and equivalents of the invention may be made without departing from the spirit and scope of the invention, and are intended to be covered by the appended claims.
