[0021] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.
[0022] Referring to Figures 1-4 , an apparatus for detecting defects on the body of a polymer plastic bottle according to an embodiment of the present invention includes a bench 1 and a mounting plate 2 fixedly connected to one side of the bench 1. A conveyor belt 7 is provided on the top of the bench 1. A rotatable turntable 3 is provided at the tail of the conveyor belt 7. A motor 17 is fixedly connected to the top of the mounting plate 2 and located at the bottom of the turntable 3. The output shaft of the motor 17 is fixedly connected to the turntable 3. A plurality of arc-shaped positioning grooves 4 are evenly formed on the outer side of the turntable 3. Air ducts 5 are fixedly connected to the inner surfaces of the positioning grooves 4 and on one side close to the middle of the turntable 3. Two vacuum suction nozzles 6 are installed on the side of each air duct 5 away from the middle of the turntable 3. A second camera 13 is provided on the top of the mounting plate 2 and below the positioning grooves 4. An L-shaped fixed frame 11 is fixedly connected to the top of the mounting plate 2 and on one side close to the second camera 13. A first camera 12 is fixedly connected to the top of the fixed frame 11 and above the positioning grooves 4.
[0023] The conveyor belt 7 conveys the bottle whose body has been detected to the turntable 3. When the motor 17 operates to drive the turntable 3 to rotate, and when the turntable 3 rotates to drive the positioning grooves 4 to rotate to the position of the bottle, the bottle moves into the positioning grooves 4 under the action of the conveyor belt 7. At this time, the vacuum suction nozzles 6 adsorb the bottle inside the positioning grooves 4. As the turntable 3 continues to rotate, the bottle moves between the first camera 12 and the second camera 13, so that the first camera 12 and the second camera 13 can detect defects on the bottle mouth and the bottle bottom of the bottle, which is beneficial to ensuring the product quality of the bottle.
[0024] A baffle plate 8 disposed near the turntable 3 is fixedly connected to the top of the stand 1 and one side close to the first camera 12. When the turntable 3 drives the bottle body inside the positioning groove 4 to rotate and move, the baffle plate 8 can prevent the bottle body from escaping from the positioning groove 4. An electric push rod 9 is also fixedly connected to the top of the stand 1 and one side close to the baffle plate 8. The end of the piston rod of the electric push rod 9 is fixedly connected to a push plate 10 disposed near the positioning groove 4. When the bottle body moves to the push plate 10 under the action of the rotating turntable 3, the electric push rod 9 drives the push plate 10 to move, so that the bottle body can be more closely in contact with the vacuum suction nozzle 6, thereby facilitating the stability of the adsorption between the vacuum suction nozzle 6 and the bottle body.
[0025] A first material discharge channel 15 and a second material discharge channel 16 are fixedly connected to one side of the mounting plate 2 away from the stand 1. The first material discharge channel 15 and the second material discharge channel 16 are arranged opposite to the positioning groove 4 up and down. One of the first material discharge channel 15 and the second material discharge channel 16 can be used as a good product discharge channel, and the other can be used as a defective product discharge channel, so as to facilitate the classification and collection of the bottles after detection.
[0026] Two guide plates 14 are symmetrically fixedly connected to the top of the stand 1 and located on both sides of the conveyor belt 7. The ends of the guide plates 14 away from the turntable 3 together form an eight-shaped structure. The guiding effect of the guide plates 14 can better convey the bottle body to the inside of the positioning groove 4. The turntable 3 and the guide plates 14 are set with gaps from the conveyor belt 7 to avoid contact friction between the turntable 3, the conveyor belt 7 and the guide plates 14.
[0027] Working principle: The conveyor belt 7 conveys the inspected bottle to the turntable 3, and the motor 17 drives the turntable 3 to rotate. When the turntable 3 rotates and drives the positioning groove 4 to rotate to the bottle, the bottle moves to the inside of the positioning groove 4 under the action of the conveyor belt 7. At this time, the vacuum suction nozzle 6 absorbs the bottle inside the positioning groove 4. As the turntable 3 continues to rotate, the bottle moves between the first camera 12 and the second camera 13, so that the first camera 12 and the second camera 13 can be used to detect defects on the bottle mouth and the bottle bottom, which is conducive to ensuring the product quality of the bottle.
[0028] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
