Description

Technical Field

[0001] The utility model relates to the technical field of screw detection, in particular to a rotary multi-angle screw detection device. Background Technique

[0002] Screws are indispensable industrial necessities in daily life. They utilize the physical and mathematical principles of the inclined plane circular rotation and friction of objects to gradually fasten the machine parts. Screws are the general term for fasteners. After the screws are produced, they need to be detected. Appearance detection is the basic item of screw detection, mainly including checking whether there are defects, damages, oil stains, etc. on the appearance of the screws;

[0003] In the prior art, the devices for screw detection have a poor display function for bolt workpieces, and the placement method of screw workpieces is relatively fixed, resulting in that the detection components can only visually detect the screw workpieces at a fixed angle and cannot comprehensively detect the workpieces. For this reason, we propose a rotary multi-angle screw detection device. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a rotary multi-angle screw detection device, which has a reliable rotation display unit. Driven by the transmission of the gear set and the rotation shaft, the self-rotation display of the screw workpiece can be realized. Cooperating with the rotation of the turntable, while rotating and displaying multiple placed screw workpieces, each screw can rotate simultaneously, ensuring that the detection lens group can comprehensively detect the surface quality of each screw workpiece; it also has a reliable screw fixing unit. When loading the screws, the three clamping plates are pushed outward by the heads of the screws, and the screws are positioned in the middle of the placement groove by the suction force of the magnetic stones, and the screws are kept in an inverted placement posture. Subsequently, the three clamping plates act together under the action of the springs to achieve a clamping effect, ensuring the stable placement of the screw workpieces during the rotation process, and effectively solving the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A rotary multi-angle screw detection device, comprising a base, a rotation display unit and a screw fixing unit;

[0006] Base: It has a circular structure and is fixedly connected with a mounting bracket on the left;

[0007] Rotating display unit: It includes a rotating disk, a first motor, a central gear, a rotating shaft, an edge gear, and a screw placement seat. The rotating disk is installed on the upper side of the base. At the center position inside the base, a second motor is embedded. The output shaft of the second motor faces upward and is fixedly connected to the central axis position of the rotating disk. The inside of the rotating disk is hollow, and at the center position of the bottom, a first motor is embedded. The output shaft of the first motor faces upward and is fixedly connected with a central gear at the end. Six vertical rotating shafts are rotatably connected to the upper end of the rotating disk. The six rotating shafts are circumferentially arrayed outside the first motor, and an edge gear is fixedly connected to the outside of the middle section of each rotating shaft. Each edge gear is meshed with the central gear. The upper end of the rotating shaft extends outward, and a screw placement seat is fixedly connected to the end of each rotating shaft;

[0008] Screw fixing unit: It is installed inside the screw placement seat.

[0009] The base is used for the stable placement of the whole device. The second motor embedded inside can drive the upper rotating disk to rotate. The screw workpieces to be detected are placed head-down in the respective screw placement seats at the upper end of the rotating disk and are rotated and displayed under the drive of the rotating disk. At the same time, the first motor inside the rotating disk drives the central gear to rotate. The central gear is meshed with the six edge gears arranged in a circumferential array on the outside, so that the six rotating shafts can be driven to rotate in the same direction through gear transmission. The rotating shafts drive the screw placement seats on the upper side to rotate in the same direction, so as to realize the self-rotation display of the screw workpieces. Cooperating with the rotation of the rotating disk, while rotating and displaying multiple placed screw workpieces, each screw can rotate simultaneously, ensuring that the detection lens group can comprehensively detect the surface quality of each screw workpiece. The screw fixing unit is used to fix the screw workpieces to ensure their own stability during the rotation process.

[0010] Furthermore, the screw fixing unit includes a placement groove and a magnetic stone. A regular hexagonal placement groove is opened inside the screw placement seat, and a magnetic stone is embedded in the center of the bottom of the placement groove. The screw workpiece is placed head-down in the placement groove, and the magnetic stone embedded in the central area of the bottom can adsorb the head of the screw, so that the screw can maintain an inverted placement posture.

[0011] Further, the screw fixing unit further comprises a telescopic rod, a spring and a clamping plate. Installation grooves are formed on three of the inner walls of the hexagonal placement groove, and there is a complete inner wall surface spaced between the three inner walls with installation grooves. Two telescopic rods perpendicular to the inner wall are fixedly connected inside the installation groove. The end of the telescopic rod is fixedly connected with the clamping plate, and a spring is sleeved outside each telescopic rod. The telescopic rod is used for installing the clamping plate, and under the action of the spring, the three clamping plates can clamp the outside of the screw head from different angles, further improving the stability when the screw workpiece is placed. When loading the screw, the three clamping plates are pushed outwards by the head of the screw, and the screw is positioned in the middle of the placement groove by the suction force of the magnetic attraction stone, and then the three clamping plates act together to achieve the clamping effect.

[0012] Further, it further comprises a detection lens group, a vision analyzer and a control panel. The vision analyzer is fixedly installed on the upper platform end of the installation frame, and the display screen of the vision analyzer is arranged on the front side. The detection lens group comprises two vision lenses. One vision lens is horizontally arranged on the upper side of the vertical section of the installation frame and faces the center position of the upper end of the rotating disk, and the other vision lens is vertically arranged at the upper horizontal end of the installation frame and corresponds vertically to the screw placement seat. The control panel is installed on the front side of the upper end of the installation frame. The control panel is used to control the start and stop of the operation of the first motor and the second motor. The two vision lenses in the detection lens group detect the screw workpiece from the vertical screen and the vertical two angles respectively to ensure the comprehensiveness of the appearance detection. The image data detected by the vision lens is transmitted to the vision analyzer. The vision analyzer realizes the detection of the screw workpiece according to the analysis and comparison of the image data, and displays the detection results through the display screen on the front side.

[0013] Further, it further comprises a background column and a supplementary light. The background column is fixedly connected to the center position of the upper end of the rotating disk, and six rod-shaped supplementary lights are installed in a circumferential array at the edge position of the upper end of the background column. The background column can ensure that when the horizontally arranged vision lens is detecting, it plays a role of blocking, preventing the other screw symmetrically placed with the current side screw from being photographed. The supplementary light arranged on the upper side can supplement the light to ensure the clarity of the imaging of the detection lens group.

[0014] Further, the rotation and display unit further comprises a fixed shaft sleeve. Six fixed shaft sleeves are fixedly connected in a circumferential array at the inner bottom end of the rotating disk, and the rotating shaft is inserted and rotatably connected inside the fixed shaft sleeve. The fixed shaft sleeve is used for limiting the rotating shaft and ensuring its stable rotation.
