Description

Technical Field

[0001] The utility model relates to the technical field of visual detection, in particular to a workbench based on visual detection. Background Art

[0002] Visual inspection is to use machines instead of human eyes to make measurements and judgments. Visual inspection refers to converting the captured target into image signals through machine vision products, transmitting them to a dedicated image processing system, and converting them into digital signals based on pixel distribution, brightness, color and other information.

[0003] Many categories of products must undergo visual inspection after production to prevent defective products from being delivered to consumers and to avoid affecting their functionality during use. Currently, visual inspection workbenches generally include a conveyor line for conveying products and a multi-axis robotic arm on one side of the conveyor line. Visual inspection cameras are installed at the working end of the robotic arm to facilitate multi-angle inspection of products. However, when existing visual inspection workbenches are used to capture images of products, it is often inconvenient to operate on the bottom surface of the product, making the entire inspection process more cumbersome and affecting inspection efficiency.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-4 The utility model provides a technical solution: a workbench based on visual inspection, including a roller conveyor line 1, a support platform 2 fixed to the top of a frame on the rear side of the middle of the roller conveyor line 1, a multi-axis robotic arm 3 installed on the top surface of the support platform 2, and a detection camera 4 installed on the working end of the multi-axis robotic arm 3.

[0030] The flip assembly includes a base 5 located at the bottom of the roller conveyor line 1, a lifting base 6 arranged above the base 5, a lifting telescopic cylinder whose bottom end of the piston cylinder is fixed to the top surface of the base 5 near the front and rear ends and whose top end of the piston rod is fixed to the front and rear walls of the lifting base 6, an annular support 7 fixed to the top of the lifting base 6 and located between two corresponding rollers of the roller conveyor line 1, a rotating ring body 8 rotatably clamped on the inner circumferential wall of the annular support 7, a clamping telescopic cylinder 9 whose piston cylinder is radially fixed to the front and rear sides of the center of the rotating ring body 8, and a clamping plate 10 fixed to the end of the piston rod of the clamping telescopic cylinder 9. The thickness of the upper half of the lifting base 6 is slightly smaller than the clear distance between two adjacent rollers on the roller conveyor line 1, so that the top of the lifting base 6 can pass through between two adjacent rollers for lifting and lowering movement.

[0031] The lifting base 6 is provided with a driving member 12 for driving the rotating ring body 8 to rotate relative to the annular support member 7. Among them, a cavity 6.1 is provided at the top of the lifting base 6, and the driving member 12 includes a servo motor 12.1 fixed to the side wall of the lifting base 6 and corresponding to the top position of the cavity 6.1, and a gear 12.2 located in the inner cavity of the cavity 6.1 and having an axial hole fixedly sleeved on the power output shaft of the servo motor 12.1, an annular groove 7.1 is provided in the middle of the inner peripheral wall of the annular support member 7, and the rotating ring body 8 is rotatably clamped in the annular groove 7.1, a rectangular notch 7.2 is provided on the bottom surface of the annular support member 7 corresponding to the position of the gear 12.2, and an outer gear ring 8.1 is provided in the middle of the outer peripheral wall of the rotating ring body 8 and meshes with the gear 12.2 through the rectangular notch 7.2.

[0032] In summary, the roller conveyor line 1 first conveys the workpiece to be visually inspected to the inspection station, and the multi-axis robot arm 3 drives the inspection camera 4 to scan and inspect the front, back, left, right and top surfaces of the workpiece; then the roller conveyor line 1 conveys the workpiece to the inner cavity position of the rotating ring body 8, and the lifting and telescopic cylinder 11 drives the lifting base 6 to move vertically so that the clamp 10 is exactly located on the front and back sides of the workpiece.

[0033] Then, the piston rod is extended by the clamping telescopic cylinder 9, so that the clamping plate 10 clamps and fixes the front and rear sides of the workpiece. The piston rod is extended by the lifting telescopic cylinder 11 again, so that the workpiece is separated from the roller on the roller conveyor line 1.

[0034] The servo motor 12.1 then drives the rotating ring body 8 to rotate 180° relative to the annular support 7 through the gear 12.2 and the outer gear ring 8.1, thereby completing the operation of turning over the workpiece.

[0035] The workpiece is then dropped onto the roller of the roller conveyor line 1 by means of the lifting and telescopic cylinder 11 , and the clamping and telescopic cylinder 9 retracts the clamping plate 10 .

[0036] Finally, the roller conveyor line 1 conveys the turned workpiece to the inspection station for scanning inspection of the back side.

[0037] In order to further ensure that the lifting base 6 moves up and down smoothly under the driving action of the lifting and telescopic cylinder 11, a guide rod 5.1 is fixed vertically on the top surface of the base 5, and a guide hole is provided on the bottom surface of the lifting base 6 to match the guide rod 5.1 in a sliding sleeve.
