[0037] The first, second, and third linear actuators are all electrically driven push rods. Each of these is electrically connected to an external power supply and an external controller, such as a computer. The arc actuator 34 is an electrically driven slide, electrically connected to the external power supply and controller. The light emitter is electrically connected to the external power supply and controller. The photoreceptor 221 is also electrically connected to the external power supply and controller.

[0038] Reference Figures 1 to 7, usage steps: ① Use manual or loading equipment (such as a robotic arm) to place the workpiece 0 on the upper surface of the second clamping claw 23, the arc driver 34 drives the second body 31 to move to the bottom end of the arc track, and the fourth clamping claw 33 moves downward until the upper surface of the fourth clamping claw 33 is flush with the upper surface of the workpiece 0; ② The moving plate 12 drives the second clamping component 3 to move in the direction close to the first clamping component 2, and synchronously causes the fourth clamping claw 33 to push the workpiece 0 in the direction close to the first clamping component 2; ③ When the end of the workpiece 0 is located between the first clamping claw 22 and the second clamping claw 23, the second clamping claw 23 moves downward and clamps the end of the workpiece 0; ④ The fourth clamping claw 33 moves upward, and when the lower surface of the fourth clamping claw 33 is higher than the upper surface of the workpiece 0, the fourth clamping claw 33 moves downward. The second clamping assembly 3 continues to move toward the direction approaching the first clamping assembly 2; ⑤ When the other end of the workpiece 0 is located between the third clamping claw 32 and the fourth clamping claw 33, the fourth clamping claw 33 moves downward and clamps the other end of the workpiece 0; ⑥ The arc driver 34 drives the second body 31 to move to the top of the arc track, and when the fourth clamping claw 33 and the second clamping claw 23 are in a vertical state, the light emitter and the photoreceptor 221 are started: Since the workpiece 0 is in a right-angle bent state, the corner 01 of the workpiece 0 is tilted outward, and the corner 01 will hinder the light of the light emitter from propagating to the photoreceptor 221, so the photoreceptor 221 can identify the workpiece 0 with a defect in the corner 01; when the workpiece 0 does not have a defect in the corner 01, the photoreceptor 221 normally receives the light of the light emitter.

[0039] The light emitter is such as a light strip, and the photoreceptor 221 is such as a photosensor. The photosensor is electrically connected to the sound alarm. When it is detected that the workpiece 0 has a corner 01 defect, the sound alarm is activated.

[0040] The workpiece 0 is such as printed books and notebooks. Generally, the folding corner 01 defect is usually located at the right angle position of the non-binding side of the workpiece 0, so refer to Figure 4 The first clamping component 2 clamps the binding side of the workpiece 0, and the second clamping component 3 clamps the middle of the non-binding side of the workpiece 0, so that the support leg position of the non-binding side is in an overhead state, thereby facilitating tilting.

[0041] The utility model has a simple structure and reliable functions. It uses the base 1, the first clamping component 2 and the second clamping component 3 to bend the workpiece 0 so that the corner 01 of the workpiece 0 is tilted outward. At the same time, it uses the light emitter and the photoreceptor 221 for identification, thereby achieving the technical purpose of detecting whether the workpiece 0 has corner defects. It is efficient, convenient and has a stable effect.
