[0038] In order to make the technical problem, technical scheme and beneficial effect solved by the utility model more clearly understood, the utility model is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0039] As Figures 1 to 6The utility model discloses an ultrasonic knife handle detection device, including pedestal 1, carrier plate 2, laser displacement sensor 3 and wireless transmitting mechanism 4, carrier plate 2 can be slidably arranged on pedestal 1, be provided with the connecting hole 21 for positioning ultrasonic knife handle on carrier plate 2, and ultrasonic knife handle is inserted in connecting hole 21. Laser displacement sensor 3 is arranged on pedestal 1, and laser displacement sensor 3 can measure the amplitude of the detection point of ultrasonic knife handle. Laser displacement sensor 3 sends laser to the detection point, and receives the laser reflected from the detection point, thereby measuring the distance between laser displacement sensor and the detection point. Since the sampling frequency of laser displacement sensor 3 is higher than the vibration frequency of ultrasonic knife handle, the peak-to-peak value in the vibration cycle of ultrasonic knife handle vibration can be detected, thereby obtaining the amplitude value of ultrasonic knife handle.

[0040] Wireless transmitting mechanism 4 includes wireless transmitting module 41 and support 42, support 42 is arranged on carrier plate 2, wireless transmitting module 41 is slidably connected on support 42, and wireless transmitting module 41 can realize wireless transmission with the wireless receiving module on ultrasonic knife handle. Carrier plate 2 can move together with support 42 when moving on pedestal 1, and then wireless transmitting module 41 moves together, since ultrasonic knife handle is positioned in connecting hole 21, so that ultrasonic knife handle and wireless transmitting module 41 always keep synchronous movement, without repeatedly adjusting the relative position of ultrasonic knife handle and wireless transmitting module 41, the detection efficiency of amplitude can be improved.

[0041] The detection point needing detection on ultrasonic knife handle has knife top position a, end ring surface position b and pull pin position c, when ultrasonic knife handle is in the normal placement state, knife top position a is upward, and the laser beam emitted by laser displacement sensor 3 irradiates to knife top position a, and the amplitude data at knife top position a can be measured. Then, carrier plate 2 is moved, so that the laser beam of laser displacement sensor 3 irradiates to end ring surface position b. Finally, carrier plate 2 is moved back to position, and ultrasonic knife handle is inverted, at this time, pull pin position c is upward, and the laser beam emitted by laser displacement sensor 3 irradiates to pull pin position c, and the amplitude detection of all detection points is completed. By moving carrier plate 2 and positioning ultrasonic knife handle through connecting hole 21, the detection of multiple detection points can be realized, without additional detection equipment, and the connecting hole 21 on carrier plate 2 can position ultrasonic knife handle, avoiding the repeated adjustment process after ultrasonic knife handle is inverted in connecting hole 21, and the detection efficiency of amplitude can be greatly improved.

[0042] In an embodiment, the ultrasonic knife handle comprises a wireless receiving module and a transducer, and the wireless power transmission principle between the wireless receiving module and the wireless transmitting module 41 is inductive magnetic field coupling. The wireless transmitting module 41 comprises a power transmitting coil, and the wireless receiving module comprises a power receiving coil. The power transmitting coil is connected with a wired power supply, and generates a high-frequency magnetic field under the excitation of current. Under the high-frequency magnetic field, the power receiving coil couples to generate a high-frequency current. The current is transmitted to the transducer through a wire, and the transducer converts the electric energy into mechanical energy, i.e., ultrasonic vibration. The laser displacement sensor 3 detects the amplitude of the ultrasonic knife handle.

[0043] In an embodiment, as shown in Figure 1 The base 1 is provided with a containing groove 111 and a limiting piece 112, and the carrier plate 2 is slidingly arranged in the containing groove 111. The carrier plate 2 can slide along the containing groove 111 to switch between the first detection position and the second detection position.

[0044] When the carrier plate 2 is at the first detection position, the laser beam of the laser displacement sensor 3 is coaxial with the connecting hole 21. When the ultrasonic knife handle is placed in the connecting hole 21, the laser displacement sensor 3 can detect the knife top position a. After the ultrasonic knife handle is turned over, the laser displacement sensor 3 can detect the pull ring position c.

[0045] When the carrier plate 2 moves from the first detection position to the second detection position, the carrier plate 2 moves towards the limiting piece 112 and abuts against the limiting piece 112, so that the movement position of the carrier plate 2 is limited by the limiting piece 112. At this time, the center axis of the connecting hole 21 deviates from the optical axis of the laser beam, and the laser displacement sensor 3 can detect the end ring surface position b. In this embodiment, the carrier plate 2 drives the ultrasonic knife handle and the wireless transmitting module 41 to move together, so that the detection of multiple detection points can be realized, and the detection efficiency is high.

[0046] The detection sequence is as follows: the ultrasonic knife handle is placed in the connecting hole 21, the carrier plate 2 is pushed to the first detection position, the laser beam of the laser displacement sensor 3 is adjusted to be coaxial with the connecting hole 21 for the first time, and the knife top position a is detected. The carrier plate 2 is moved to the second detection position, and the end ring surface position b is detected.
