[0002] In automation equipment, the clamping device is the most common equipment, which is used for loading and unloading products or parts in production; due to the clamping of products or parts, the splint needs to exert force on the parts or products; but this clamping force It is difficult to control. If the clamping force is too large, the product clamp will be deformed and affect the product quality; if the clamping force is too small, the product will fall during the clamping process due to lack of clamping force, causing product damage; existing In technology, in order to accurately control the clamping force of the splint on the product, a clamping force control component is often installed on the splint; however, adding a clamping force control component to the splint requires increasing the size of the splint or changing the shape of the splint. more troublesome and inconvenient

[0003] Chinese patent (notification number: CN207841138U) discloses a clamping device with a pressure sensor, including a controller, a servo motor electrically connected to the controller, a transmission mechanism connected to the servo motor, and the transmission mechanism is connected to the transmission mechanism through transmission pins respectively. And the left jaw and the right jaw that can move toward each other or move back under the action of the transmission mechanism, the two transmission pins are provided with wings, and the two wings are in close contact with the transmission mechanism, and at least one wing A thin-film pressure sensor is inserted between the sheet and the transmission mechanism, and the pressure sensor is electrically connected to the controller; the device inserts a thin-film pressure sensor on the contact surface between the transmission pin and the transmission block, without changing the original Under the premise of the jaw design, the pressure value of the contact surface can be measured to obtain a more accurate clamping force. However, the device needs to control the clamping force through the motor. The control method is too complicated and the operation is difficult. Therefore, it is necessary to The device is improved
