[0016] The following combines the drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0017] The specific technical solutions implemented by the present utility model are as follows:

[0018] As Figure 1As shown in the figure, a metal sheet missing detection device for a plastic assembly cover includes: a horizontal conveyor belt 1 extending in the left-right direction and used for conveying the plastic assembly cover 9, a collection box 2 provided on the front side of the conveyor belt 1 with an open top and a top surface flush with the top surface of the conveyor belt 1 and used for receiving the plastic assembly cover 9 missing the metal sheet, a vertical plate 3 provided on the rear side of the conveyor belt 1 and facing the collection box 2, a U-shaped enclosure 21 extending upward from the top of the collection box 2 with a notch facing the vertical plate 3, a first induction device 4 provided at the front end of the vertical plate 3, above the top surface of the conveyor belt 1, close to the top surface of the conveyor belt 1 and used for sensing the plastic assembly cover 9, a second induction device 5 provided directly above the conveyor belt 1 and facing the vertical plate 3 and used for sensing the metal sheet in the plastic assembly cover 9, a cross plate 6 provided directly above the conveyor belt 1 and supporting the second induction device 5, a telescopic cylinder 7 provided at the front end of the vertical plate 3 with a telescopic end connected to the rear end of the cross plate 6 and used for driving the cross plate 6 to lift and lower, a blowing head 81 provided at the front end of the vertical plate 3, above the top surface of the conveyor belt 1, close to the top surface of the conveyor belt 1, close to the first induction device 4 and used for blowing the plastic assembly cover 9 missing the metal sheet into the collection box 2, an air supply pipe 82 externally connected to the rear end of the vertical plate 3 and communicating with the blowing head 81, an air supply device communicating with the blowing head 81 through the air supply pipe 82, a blowing solenoid valve provided on the air supply pipe 82, and a main control unit electrically connected to the first induction device 4, the second induction device 5, and the blowing solenoid valve respectively; the first induction device 4 is a photoelectric switch; the second induction device 5 is a metal detector.

[0019] The working principle of the metal sheet missing detection device for the plastic assembly cover of the present utility model includes:

[0020] Place the plastic assembly cover 9 on the top surface of the conveyor belt 1 and convey it at intervals in the left-right direction; when a certain plastic assembly cover 9 is conveyed between the vertical plate 3 and the collection box 2, the first induction device 4 (photoelectric switch) senses the plastic assembly cover 9 and uploads a first induction signal to the main control unit; and the second induction device 5 (metal detector) senses the metal sheet in the plastic assembly cover 9 and uploads a second induction signal to the main control unit; if the plastic assembly cover 9 is missing the metal sheet, the second induction device 5 (metal detector) does not upload a second induction signal to the main control unit; the main control unit controls the blowing solenoid valve to open only when it receives the first induction signal and does not receive the second induction signal; and when the blowing solenoid valve is open, the air supply device supplies air to the blowing head 81 through the air supply pipe 82, and then the blowing head 81 blows out gas to blow the plastic assembly cover 9 missing the metal sheet into the collection box 2; the plastic assembly cover 9 not missing the metal sheet can pass normally;

[0021] The U-shaped enclosure 21 extending upward from the top of the collection box 2 with a notch facing the vertical plate 3 can prevent the plastic assembly cover 9 from flying over the collection box 2 and prevent the plastic assembly cover 9 from falling outside the collection box 2;

[0022] The second induction device 5 is supported by a horizontal plate 6, and the horizontal plate 6 is supported by a telescopic cylinder 7; the telescopic cylinder 7 can drive the second induction device 5 to move up and down through the horizontal plate 6 so as to adjust the vertical gap between the second induction device 5 and the top surface of the conveyor belt 1, so that the vertical gap is adapted to the thickness of the plastic assembly cover 9 (so that the vertical gap can allow the plastic assembly cover 9 to pass through).

[0023] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
