Description

Technical Field

[0001] The utility model relates to the technical field of vision detection equipment, in particular to a machine vision detection equipment. Background Technique

[0002] Machine vision detection equipment is an advanced automated detection technology tool. It utilizes optical, image processing, and computer hardware and software technologies to simulate and expand the visual functions of humans, so as to achieve functions such as automated dimensional measurement, defect detection, surface quality assessment, color recognition, shape matching, and position judgment of products or target objects. At present, the combination of deep learning and machine vision has brought a revolutionary change to industrial instrument detection. The combination of image recognition and pattern matching not only improves the accuracy and efficiency of detection, but also greatly reduces the labor cost.

[0003] A machine vision detection equipment with the publication number of CN220566986U in the prior art includes a workbench. A top cover is arranged at the top end of the workbench. A second limiting chute is opened in the middle of the top cover. An annular rack is fixedly connected to the bottom end inside the second limiting chute. A housing is arranged in the middle of the top cover. A double-shaft motor is fixedly connected inside the housing. Both sides of the double-shaft motor are movably connected with rotating shafts, and the rotating shafts penetrate through the housing.

[0004] Although this machine vision detection equipment can make the camera detect the product 360°, it can only detect the upper surface and side surface of the product, and cannot detect the defects on its bottom, thus reducing the detection range. When it is necessary to detect the bottom of the product, a secondary detection operation is required, which is not only troublesome, but also increases the time required for detection, thereby reducing the detection efficiency. Content of the Utility Model

[0005] The utility model is a machine vision detection equipment proposed to solve the defects existing in the prior art.

[0007] Two chambers are symmetrically opened inside the rotating table. One side of the inner top of each of the two chambers is fixedly connected with a perforated rubber block penetrating to the top. A pneumatic piston is jointly installed between each of the two chambers and the rotating table;

[0008] A pneumatic lifting component is fixedly installed on the workbench of the body. A double-shaft cylinder is fixedly installed at the movable end of the pneumatic lifting component. Both movable ends of the double-shaft cylinder are fixedly connected with fixed rods.

The top of the driven gear is fixedly connected with a rotating shaft, and the rotating shaft penetrates through the body and is rotatably connected therewith. And the rotating shaft is fixedly connected with the rotating table, which is convenient for driving the rotating table to rotate.

[0011] Furthermore, the bottom of the rotating table is slidably connected with a circular slide rail, and the circular slide rail is fixedly connected with the body. The circular slide rail has a supporting effect on the rotating table, which is beneficial to the rotation of the rotating table.

[0012] Furthermore, both of the pneumatic pistons include telescopic cylinders, and the telescopic cylinders are fixedly installed inside the rotating table. The movable ends of the telescopic cylinders penetrate into the chamber and are fixedly connected with piston bodies, and the piston bodies are hermetically attached to the inner walls of the chambers. The telescopic cylinders can drive the piston bodies to move inside the chambers, thereby generating air extraction or exhaust phenomena.

[0013] Furthermore, the pneumatic lifting component includes a mounting plate, and the mounting plate is fixedly connected with the body. A lifting cylinder is fixedly installed at the top of the mounting plate. The movable end of the lifting cylinder is fixedly connected with a sliding seat, and the sliding seat is fixedly connected with the double-shaft cylinder, which can drive the sliding seat to rise or fall, and thus can drive the double-shaft cylinder to rise or fall.

[0014] Furthermore, on one side of the outer surface of the mounting plate, two guide rails are symmetrically and fixedly connected, and the guide rails are slidably connected with the sliding seat. The guide rails have a limiting effect on the sliding seat, and can ensure the stability of the up and down movement of the sliding seat.
