[0003] In the related art, the structure includes a displacement mechanism, a connecting plate, a clamping jaw mechanism, and a magnetic induction mechanism. The connecting plate is arranged on the output end of the displacement mechanism. The clamping jaw mechanism includes an upper clamping plate, a clamping cylinder, and a lower clamping plate.

The magnetic tape is arranged on the lower clamping plate, and the magnetic induction head is arranged on the upper clamping plate. The magnetic induction head is used to detect the position of the magnetic tape. When the clamping jaw mechanism clamps the plate, the magnetic induction head detects the displacement change of the magnetic tape to calculate the number of plates.

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] The embodiment of the present application discloses a detection structure for feeding board materials.

[0024] Reference Figures 1 to 5 A detection structure for feeding board materials includes a rack 1, an upper clamping jaw 2, a lower clamping jaw 3, an angle encoder 4, and a driving mechanism 6. Specifically, the upper clamping jaw 2 and the lower clamping jaw 3 are respectively arranged opposite to each other on the rack 1, and are arranged in a vertical direction. The angle between the upper clamping jaw 2 and the lower clamping jaw 3 can be opened and closed, and the upper clamping jaw 2 and the lower clamping jaw 3 are used for the board material to extend therebetween. The housing of the angle encoder 4 is fixedly arranged on the rack 1, and the angle encoder 4 is used for detecting the angle opened between the upper clamping jaw 2 and the lower clamping jaw 3. The driving mechanism 6 is connected with the rack 1, so as to move the rack 1 as a whole, and make the board material extend to a predetermined distance between the upper clamping jaw 2 and the lower clamping jaw 3.

[0025] In the embodiment, the lower clamping jaw 3 is fixedly arranged on the frame 1 and is in a horizontal state in use, a rotating shaft 5 is arranged on the frame 1 and is rotatably arranged on the frame 1, the rotating shaft 5 is used for fixing one end of the upper clamping jaw 2 to pass through, so that the upper clamping jaw 2 rotates synchronously with the rotating shaft 5, and the shaft of the angle encoder 4 is connected with the rotating shaft 5. In the embodiment, the shaft of the angle encoder 4 is inserted into the rotating shaft 5, and when the rotating shaft 5 rotates, the shaft of the angle encoder 4 rotates synchronously. When the plate material extends into the clamping opening between the upper clamping jaw 2 and the lower clamping jaw 3, the upper clamping jaw 2 rotates under the action of the plate material to open the clamping opening. After the plate material extends into the clamping opening by a predetermined distance, the angle encoder 4 detects the angle of rotation of the rotating shaft 5 to calculate the number of plate materials. Compared with the method of calculating the number of plate materials by sensing the displacement change of the magnetic tape by the magnetic induction head, the overall structure of the present scheme is more compact, occupies less space, and the data measured by the angle encoder 4 is more reliable.

[0026] With reference to Figures 3 to 5 The driving mechanism 6 includes a horizontal driving member 61 and a vertical driving member 62. The horizontal driving member 61 is fixedly arranged on the external structure, and the vertical driving member 62 is connected to the output end of the horizontal driving member 61, so that the vertical driving member 62 moves in the horizontal direction as a whole. The frame 1 is connected to the output end of the vertical driving member 62. When the vertical driving member 62 works, the frame 1 can move in the vertical direction as a whole. In the embodiment, the horizontal driving member 61 and the vertical driving member 62 are both gas cylinders. Therefore, when measuring the number of plate materials, the vertical driving member 62 and the frame 1 are first extended as a whole by the horizontal driving member 61, and then the frame 1 is lowered to a predetermined position by the vertical driving member 62, so that the clamping opening between the upper clamping jaw 2 and the lower clamping jaw 3 is aligned with the plate materials to be measured. Then, the horizontal driving member 61 is retracted, so that the plate materials are clamped into the clamping opening by a predetermined distance. The number of plate materials can be calculated by the angle of rotation of the upper clamping jaw 2.

[0027] With reference to Figures 3 to 5 In the embodiment, in order to avoid measurement deviation, a clamping torsion spring 7 is arranged on the frame 1. One end of the clamping torsion spring 7 is fixedly connected with the frame 1, and the other end is connected with the upper clamping jaw 2, so that the upper clamping jaw 2 always has a tendency to rotate towards the lower clamping jaw 3. That is, in the initial state, the upper clamping jaw 2 is tightly attached to the lower clamping jaw 3 to be in a horizontal state. When the plate material extends into the clamping opening between the upper clamping jaw 2 and the lower clamping jaw 3, the upper clamping jaw 2 is always pressed against the upper side of the plate material, so that the angle of rotation of the upper clamping jaw 2 is as accurate as possible, and the measurement result of the angle encoder 4 is not inaccurate due to shaking.

[0028] With reference to Figures 3 to 5, and in order to facilitate the board to extend into the gap between the upper clamping jaw 2 and the lower clamping jaw 3, the following settings are provided, one is that a guide inclined surface 8 is arranged on the side of the upper clamping jaw 2 close to the lower clamping jaw 3, the guide inclined surface 8 is arranged at the end away from the rotating shaft 5, and a corresponding guide inclined surface 8 is also arranged on the lower clamping jaw 3, and the two guide inclined surfaces 8 on the upper clamping jaw 2 and the lower clamping jaw 3 are in an open outward angle in the initial state, so when the board extends into the gap between the upper clamping jaw 2 and the lower clamping jaw 3, it will first abut against the guide inclined surface 8, and through the guiding effect of the guide inclined surface 8, the board is sent into the gap, avoiding collision to cause damage to the equipment; the second is that a guide wheel 9 is arranged on the side close to each other of the upper clamping jaw 2 and the lower clamping jaw 3, the guide wheel 9 is arranged close to the guide inclined surface 8, and the outer side wall of the guide wheel 9 is used to abut against the board, avoiding scratching the board when the board extends into the gap.

[0029] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
