Detailed Implementation

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Example:

[0049] Please refer to the following: Figure 1-5 ,

[0050] A multi-angle machine vision information acquisition device, comprising:

[0051] The base plate 1, which is square in shape, is used to support the connection.

[0052] The U-shaped frame 2 is welded to the top of the base plate 1, and the side of the U-shaped frame 2 away from the base plate 1 is square.

[0053] The drive motor 4 is located at the bottom of the U-shaped frame 2. Motor 4 is a DC motor.

[0054] Controller 3, located on top of U-shaped frame 2, is used to control the operation of motor 4;

[0055] The arc-shaped rod 5 is used to support the connection and is located at the output end of the motor 4;

[0056] At least two cameras 6 are fixedly mounted on the outside of the arc-shaped rod 5;

[0057] The LED flicker-free supplementary light 7 used for lighting is set at the geometric center of the arc-shaped rod 5;

[0058] A striking plate 8 is used to control the switch and is fixedly sleeved on the output end of the motor.

[0059] Support plate 9 is fixedly welded to the outside of U-shaped frame 2;

[0060] Automatic reset switch 10 and automatic reset switch 21 are provided. Automatic reset switch 10 is fixedly installed on the front side of support plate 9 and automatic reset switch 21 is fixedly installed on the back side of support plate 9.

[0061] Multiple support rods 12 are arranged in a ring on the base plate 1, directly above the base plate 1.

[0062] Support plates 9 are used for connection and are fixedly welded to the top of multiple support rods 12;

[0063] Motor 2 14 is used for driving and is fixedly mounted on the top of base plate 1;

[0064] Inclined plate 15 is rotatably connected inside annular plate 13, and the geometric center of inclined plate 15 is fixedly connected to the output end of motor 14.

[0065] Four L-shaped rods 16 are slidably disposed inside the annular plate 13;

[0066] Placement plate 17 is used to place the items to be collected. Placement plate 17 is fixedly welded to the inside of four L-shaped rods 16.

[0067] Two arc plates 18 are used to press the placement plate 17 to move, and the two arc plates 18 are fixedly welded to the bottom of the placement plate 17;

[0068] Specifically, when using this device, the item needs to be placed at the center of the placement plate 17, preferably in the center position. Then, manually press the automatic reset switch 10 on the side away from the striking plate 8. After pressing the automatic reset switch 10, the first relay inside the dual-channel relay module is activated, and the motor 4 rotates forward. The forward rotation of the motor 4 drives the striking plate 8 to rotate in the forward direction. When the striking plate 8 rotates to nearly 360 degrees, the automatic reset switch 11 is activated. Because of the setting of the support plate 9, the striking plate 8 can only rotate between 355 and 358 degrees and cannot rotate 360 ​​degrees. The second relay inside the dual-channel relay module is activated. At this time, the motor 4 reverses, which can enable the motor 4 to drive the arc rod 5 to rotate in a ring.

[0069] When motor 4 rotates, it will drive the arc rod 5 to rotate, which in turn will drive the LED flicker-free fill light 7 and multiple cameras 6 to rotate, achieving the effect of circular scanning of items on the placement plate 17.

[0070] To ensure the integrity of the scan, motor 2 14 needs to be turned on and rotated slowly. Motor 2 14 will drive the tilting plate 15 and the guide plate to rotate. Under the pressure of the guide plate, the arc plate 18 will be moved upward. At this time, the arc plate 18 will drive the placement plate 17 to move upward slowly, so that the position of the item on the placement plate 17 changes within the illumination range of the camera 6, making the information collected by the camera 6 more complete.

[0071] The LED flicker-free fill light 7 has a fill light effect, which can supplement light in the case of insufficient light and achieve better collection effect;

[0072] In the embodiment: the top of the inclined plate 15 is provided with two guide plates, and the two guide plates are arranged in an arc shape, and the two guide plates are respectively arranged in correspondence with the two arc plates 18;

[0073] Specifically, the top of the inclined plate 15 is provided with two guide plates, which are arranged in a corresponding manner with the arc plate 18. This allows the plate 17 to be squeezed, enabling it to move up and down, thus moving the item up and down. This allows for a more comprehensive scanning of the item and the collection of information from all directions.

[0074] In the embodiment, it also includes:

[0075] Several anti-slip grooves are provided on the top of the placement plate 17 for preventing slipping.

[0076] The surface of the placement plate 17 and the inner sides of several anti-slip grooves are coated with an anti-slip coating. The anti-slip coating adopts a composite structure of epoxy resin, inorganic sand particles and polyurethane.

[0077] Specifically, the multiple anti-slip grooves can achieve an anti-slip effect, effectively preventing items from moving when the placement plate 17 moves up and down, thus preventing errors in the collection of item information due to item movement during device operation. The anti-slip coating can better achieve the anti-slip effect, and the placement plate 17 only needs to move up and down, without rotating or moving laterally, which can, to a certain extent, prevent items from shifting during information collection.

[0078] In this embodiment: the controller 3 includes:

[0079] A microprocessor is used to run control programs;

[0080] The storage module is used to store preset algorithm parameters;

[0081] A communication interface for bidirectional communication with external sensors;

[0082] In this embodiment: the controller 3 is internally equipped with a dual-channel relay module, and the dual-channel relay module is electrically connected to the automatic reset switch 10 and the automatic reset switch 11 via a power line. The dual-channel relay module includes a first relay and a second relay.

[0083] Specifically, during use, when the automatic reset switch 10 is pressed by the tapping plate 8, the first relay inside the dual-channel relay module is activated, the motor 4 rotates forward, and the tapping plate 8 rotates slowly. When the tapping plate 8 presses the automatic reset switch 11, the second relay inside the dual-channel relay module is activated, and the motor 4 rotates in reverse. This can achieve the effect of driving the arc rod 5 to rotate forward and in reverse, thus achieving the effect of circumferential scanning.

[0084] In the embodiment: both sides of the support plate 9 are provided with limiting grooves, and the limiting grooves on both sides can be correspondingly set with the striking plate 8;

[0085] Specifically, limit grooves are provided on both sides of the support plate 9, and automatic reset switch 10 and automatic reset switch 21 are fitted inside the limit grooves. The limit grooves are set in correspondence with the striking plate 8 to achieve the effect of accurately striking and touching the automatic reset switch 10 and automatic reset switch 21.

[0086] In the embodiment: the LED flicker-free fill light 7 is positioned directly above the placement plate 17, and the LED flicker-free fill light 7 is located at the symmetrical axis of the multiple cameras 6, and the LED flicker-free fill light 7 is arranged in an arc shape;

[0087] Specifically, the LED flicker-free fill light 7 is positioned directly above the placement plate 17, which can illuminate the items to be collected, ensuring sufficient light to illuminate the items and achieve a fill light effect in low light conditions. The LED flicker-free fill light 7 is located at the symmetrical axis of multiple cameras 6, which can achieve a better fill light effect. The LED flicker-free fill light 7 is set in an arc shape, which can better fill light on the items.

[0088] Working principle: When using this device, place the item at the center of the placement plate 17, manually press the automatic reset switch 10 on the side away from the striking plate 8, the first relay inside the dual-channel relay module will engage, the motor 4 will rotate forward and drive the striking plate 8 to rotate forward. When the striking plate 8 rotates to nearly 360 degrees, it will strike the automatic reset switch 11, the second relay inside the dual-channel relay module will engage, the motor 4 will rotate in reverse and drive the arc rod 5 to rotate in a circle. The rotation of the motor 4 drives the arc rod 5 to rotate, which in turn drives the LED flicker-free fill light 7 and multiple cameras 6 to rotate, achieving the effect of circular scanning of the item on the placement plate 17 and achieving the effect of collecting information from multiple angles.

[0089] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
