Abstract
Description
Technical Field
[0001] This utility model relates to the field of appearance inspection technology, and in particular to an intelligent instrument for detecting appearance defects in button batteries. Background Technology
[0002] Visual inspection is a process that detects the quality of a workpiece surface based on human sensory judgment or by scanning with equipment.
[0003] In existing button cell battery appearance defect inspection equipment, the button cell battery is transported by rotating optical glass turntable. The front, back and outer perimeter of the button cell battery are photographed and inspected by optical cameras positioned above, below and at an angle. The upper and lower cameras can clearly and completely capture the top, bottom and edge features of the button cell battery, while the side camera can only capture a relatively simple image of the tilted outer perimeter. Moreover, the button cell battery cannot rotate, and the shooting position is relatively limited. This results in insufficient accuracy in the appearance quality inspection of the outer perimeter.
[0004] To address the aforementioned issues, an intelligent instrument for detecting appearance defects in button batteries is proposed. Utility Model Content
[0005] The main purpose of this invention is to provide an intelligent instrument for detecting appearance defects in button batteries, which solves the problems mentioned in the background art.
[0006] The objective of this utility model can be achieved by adopting the following technical solution:
[0007] A smart instrument for detecting defects in the appearance of button batteries includes a base, a rotating power unit is provided at the center of the inner wall of the base, a rotating detection platform is fixed on the rotating power unit and supported by several short shafts, a series of button batteries are placed on the rotating detection platform, and a detection mechanism is provided between adjacent button batteries.
[0008] The detection mechanism includes a fixed frame fixed to the outer wall of the base. A reciprocating screw is rotatably mounted on the bottom surface of the top plate of the fixed frame. A movable detection ring is fitted on the threaded surface of the reciprocating screw. Four sets of peripheral detection cameras are arranged in the inner wall of the ring handle at one end of the movable detection ring. An upper detection camera and a lower detection camera are also arranged directly above and below the movable detection ring.
[0009] Furthermore, the rotating power unit includes a power motor fixed inside the base, and a base plate that rotates along the inner ring of the top of the base is fixed on the output shaft of the power motor.
[0010] Furthermore, the rotating detection stage is a transparent optical detection glass, with a metal ring fixed to its outer wall, and a first gear is fixedly fitted around the outside of the metal ring.
[0011] Furthermore, a second gear is externally engaged with the first gear, and the second gear is fixedly sleeved on the bottom of the reciprocating lead screw.
[0012] Furthermore, guide plates are fixedly provided on both sides of the outer wall of the movable detection ring, and the guide plates slide along the groove of the outer wall of the upper detection camera.
[0013] Furthermore, an air pump, a controller, and a display screen are electrically connected to the top and outer wall of the fixed frame, and a feeding blowing nozzle and a sorting blowing nozzle are connected to the output end of the air pump through a pipe.
[0014] Furthermore, a feeding conveyor plate is slidably connected to the rotating detection platform.
[0015] The beneficial technical effects of this utility model are as follows:
[0016] This invention designs a side-mounted imaging detection mechanism that moves synchronously up and down, allowing it to move up and down within the conveying gap of the button battery, following the rotation of the rotating inspection table. The rotating inspection table uses a first gear to drive a second gear to rotate a reciprocating lead screw, thereby enabling four optical cameras to capture images of the outer peripheral wall of the button battery from the front with a 90° coverage area. This improves the accuracy of image acquisition and facilitates high-quality detection of defects on the outer wall of the button battery by image analysis software. Attached Figure Description

[0022] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0023] like Figures 1-3 As shown, this embodiment provides an intelligent inspection instrument for button battery appearance defects, including a base 1. A rotating power unit 4 is arranged at the center of the inner wall of the base 1. A rotating inspection table 3 supported by several short shafts is fixed on the rotating power unit 4. A series of button batteries are placed on the rotating inspection table 3, and an inspection mechanism 5 is arranged between adjacent button batteries. The inspection mechanism 5 includes a fixed frame 501 fixed to the outer wall of the base 1. A reciprocating screw 505 is rotatably installed on the bottom surface of the top plate of the fixed frame 501. A moving inspection ring 506 is fitted on the threaded surface of the reciprocating screw 505. Four sets of peripheral inspection cameras 510 are arranged in the inner wall of the ring handle at one end of the moving inspection ring 506. An upper inspection camera 507 and a lower inspection camera 508 are also arranged directly above and below the moving inspection ring 506.
[0024] In the above structure, the upper inspection camera 507, the lower inspection camera 508, and the peripheral inspection camera 510 are all optical inspection cameras equipped with micro-focus lenses, and the collected data is processed and analyzed through a visual inspection software platform.
[0025] The length of the lead screw 505 is 10-15cm, and the gap between the button battery and the rotary testing stage 3 is 5-8cm.
[0026] The rotating power unit 4 includes a power motor fixed inside the base 1, and a base plate that rotates along the inner ring of the top of the base 1 is fixed on the output shaft of the power motor.
[0027] The rotating testing stage 3 is made of transparent optical testing glass, with a metal ring fixed to its outer wall. A first gear 301 is fixedly fitted around the outside of the metal ring. A second gear 505a meshes with the outside of the first gear 301 and is fixedly fitted around the bottom of the reciprocating lead screw 505.
[0028] In the above structure, the gear ratio between the first gear 301 and the second gear 505a is 25:1, which allows the moving detection ring 506 to move up and down quickly within the stroke of the reciprocating screw 505, so that it can fall on the table surface of the rotating detection stage 3 located between adjacent button batteries, and the peripheral detection camera 510 can quickly capture the image of the outer peripheral wall of the button battery.
[0029] The transparent optical inspection glass allows the inspection camera 508 to take pictures of the bottom of the button battery through the optical glass.
[0030] Guide plates 509 are fixedly installed on both sides of the outer wall of the moving detection ring 506. The guide plates 509 slide along the groove on the outer wall of the upper detection camera 507. The guide plates 509 provide vertical guidance when the moving detection ring 506 moves up and down, and keep it in horizontal contact with the rotating detection stage 3.
[0031] An air pump 503, a controller 502, and a display screen 504 are electrically connected and fixed on the top and outer wall of the mounting frame 501. The output end of the air pump 503 is connected to a feeding blow nozzle 503a and a sorting blow nozzle 503b, which are connected by pipes. The controller 502 is equipped with an analysis system for processing data captured by the optical camera. The data analysis screen is displayed in real time on the display screen 504. After the sorting blow nozzle 503b analyzes the defective product, it passively starts the airflow through the controller 502 to blow the defective product away from the rotating inspection table 3. The feeding blow nozzle 503a operates continuously and is equipped with a receiving device. Limiting track grooves are provided on the contact surfaces of the feeding blow nozzle 503a and the sorting blow nozzle 503b with the rotating inspection table 3 to provide rotation guidance.
[0032] A feeding conveyor plate 2 is slidably connected to the rotating testing table 3.
[0033] The working principle of this device is as follows:
[0034] This device requires an external power source during use.
[0035] The feeding conveyor plate 2 sequentially feeds the button batteries onto the rotary inspection table 3. As the rotary inspection table 3 rotates, the first gear 301 drives the second gear 505a in the inspection mechanism 5 to rotate. The second gear 505a drives the reciprocating screw 505 to rotate, causing the moving inspection ring 506 to move up and down, reciprocating between the rotary inspection table 3 and the upper inspection camera 507. The moving inspection ring 506 can spiral within the gaps between adjacent button batteries, lightly touching the top of the rotary inspection table 3. The four sets of peripheral inspection cameras 510 cover the area at 90° angles. The cover area captures a full view of the outer periphery of the button battery. The image data, along with the data captured by the upper detection camera 507 and the lower detection camera 508, is simultaneously entered into the image processing software in the controller 502 for analysis and comparison. When the detected defective product is lifted by the moving detection ring 506, the defective product is removed. The controller 502 then instructs the air pump 503 to open the valve of the sorting and blowing nozzle 503b, blowing the defective product into the NG sorting and storage container. Good products are continuously blown into the feeding collection device at the feeding and blowing nozzle 503a.

Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller.
