[0002] Ultrasonic knife is an ultrasonic wave that can cut the internal tissue of the human body like a real knife by using the ultrasonic principle. Ultrasonic knife mainly consists of main unit, driving handle and connection line, blade and foot switch, etc. Its working principle is to use foot pedal or handheld blade to activate the work. At this time, the main unit outputs electrical energy at the resonance frequency of the vibration system to the driving handle, which converts the electrical energy into mechanical energy and outputs it to the blade. The blade further amplifies this vibration and vibrates mechanically, so that the water in the tissue cells is vaporized, the protein hydrogen bonds are broken, the cells are disintegrated, the tissue is cut or coagulated, so as to achieve the purpose of cutting tissue and stopping bleeding. The shell of ultrasonic knife is usually composed of two left and right shells, which are connected by interference fit. When assembling such shells, manual operation is very laborious. Generally, a stamping machine is used to complete the assembly work. However, the stamping action of the stamping machine is fast. When assembling the shell of hard plastic material, it is easy to damage the shell due to too fast pressing speed. In addition, it is easy to produce scrap because the two shells are not aligned, resulting in a high scrap rate. Utility Model Content

[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] Reference Figures 1 to 4As shown, a pressing device for an automated production line according to an embodiment of the utility model comprises: a frame 100, a pushing device 300, a support plate 400, a pressing plate 600, a driving device 700, and a visual inspection device 800. Four guide rods 200 are vertically arranged on the frame 100; the four guide rods 200 are symmetrically arranged. The guide rods 200 are welded to the frame 100. The guide rods 200 are round rods with smooth surfaces. The pushing device 300 is installed on the frame 100; the pushing device 300 uses a cylinder, and the support plate 400 is located above the pushing device 300, and the support plate 400 moves along the slide rail under the drive of the cylinder. The upper end of the support plate 400 is used to place the material 500. The material 500 is two shells connected by interference fit. The pusher device 300 can drive the support plate 400 to move from the detection position to the pressing position. The pressing plate 600 is slidably connected to the guide rod 200. The pressing plate 600 is horizontally arranged. Multiple guide rods 200 guide the pressing plate 600 at the same time, so that the pressing plate 600 can maintain stable movement when it is lifted or lowered. The pressing plate 600 is used to press the material 500 on the support plate 400 at the pressing position; when the pressing plate 600 descends, it can press the two shells of the stapler to fix the two shells together. The driving device 700 is used to drive the pressing plate 600 to move along the guide rod 200; the driving device 700 is fixedly connected to the guide rod 200. The visual detection device 800 is connected to the frame 100 and is arranged directly above the support plate 400 at the detection position. A protective cover is provided on the frame, and the visual detection device 800 is arranged in the protective cover. The protective cover is provided with an observation hole for an industrial camera to take pictures. The visual inspection device 800 includes an industrial camera, a controller, a detection comparison module, and an acoustic and visual alarm. The industrial camera takes pictures of the two shells on the pallet 400 located at the detection position, and the detection comparison module stores images of correctly aligned and correctly assembled parts in the shell. The pictures taken by the industrial camera are transmitted to the detection comparison module, and the detection comparison module compares the appearance feature information of the pictures taken by the industrial camera with the images of correctly assembled parts in the shell. If the similarity reaches the set value, the detection comparison module determines that the parts in the shell being inspected are assembled correctly; if the set value is not reached, it is determined that the parts in the shell are assembled incorrectly, and then the information of the incorrect assembly of the parts in the shell is transmitted to the acoustic and visual alarm, and the acoustic and visual alarm sends an acoustic and visual alarm signal to remind the staff to handle it. The set value can be set according to different product requirements. It can be foreseen that if the parts in the shell are assembled correctly, the pusher device 300 will move the pallet 400 to the pressing position, and if the parts in the shell are assembled incorrectly, the pallet 400 will stay at the detection position and wait for processing.

[0039] Reference Figure 3As shown, it can be understood that the top end of the guide rod 200 is bolted to the mounting plate 210, the top center of the guide rod 200 is provided with a threaded hole, the mounting plate 210 is provided with a fixing screw, and the fixing screw is threadedly connected in the threaded hole. The driving device 700 includes an actuating cylinder 710 and a control valve group 720. The actuating cylinder 710 selects a common double-acting thin-walled cylinder. The fixed end of the actuating cylinder 710 is bolted to the mounting plate 210, the telescopic end of the actuating cylinder 710 passes downward through the mounting plate 210 and is connected to the pressing plate 600, the outlet of the control valve group 720 is connected to the actuating cylinder 710, and the inlet of the control valve group 720 is connected to a compressed air source, and the compressed air source can be selected from an air compressor or a compressed air pipeline. The control valve group 720 is used to control the pressure of the compressed air input to the actuating cylinder 710. The control valve group 720 uses a manual pressure regulating valve. If the pressure value required for pressing the material 500 is too large, the material 500 will be damaged, while if the pressure value is too small, the material 500 cannot be completely pressed. Therefore, the pressure on the material 500 needs to be limited within a suitable range. The pressure on the material 500 is approximately equal to the force exerted by the telescopic end of the actuator cylinder 710 on the pressing plate 600. The operator manually controls the opening of the manual pressure regulating valve to change the pressure of the compressed air input to the actuator cylinder 710, thereby changing the force exerted on the pressing plate 600 when the actuator cylinder 710 moves downward, so that the material 500 can be pressed with a suitable pressure.

[0040] Reference Figure 2 and Figure 3 As shown, it can be understood that a pressure sensor 900 is provided between the upper end of the pressing plate 600 and the telescopic end of the actuator cylinder 710. The pressure sensor 900 is a planar pressure sensor 900. When the telescopic end of the actuator cylinder 710 descends, the pressing plate 600 is pressed by the pressure sensor 900, so the pressure sensor 900 can measure the force exerted on the pressing plate 600 when the actuator cylinder 710 moves downward. Since the operator cannot directly know the force exerted when the actuator cylinder 710 moves downward after adjusting the control valve group 720, it is necessary to set the pressure sensor 900 for measurement.

[0041] Reference Figure 2 , Figure 3 As shown, it can be understood that a display 211 is connected to the upper end of the mounting plate 210, and the display 211 is electrically connected to the pressure sensor 900. The display 211 is used to display the pressure value measured by the pressure sensor 900. The operator can intuitively observe the change in the measured value of the pressure sensor 900 after adjusting the control valve group 720 from the display 211, so as to control the downward pressure of the pressing plate 600 within a suitable range to ensure product quality.

[0042] Reference Figure 3As shown, it can be understood that the upper end of the pressure plate 600 is detachably connected with a mounting cylinder 610, and the mounting cylinder 610 is bolted to the pressure plate 600. The top of the mounting cylinder 610 is closed, and the bottom of the mounting cylinder 610 is open to facilitate the installation of the pressure sensor 900. The outer peripheral wall of the lower end of the mounting cylinder 610 is provided with a flange, and the flange is bolted to the pressure plate 600. The top of the mounting cylinder 610 is provided with a mounting hole 620 for the telescopic end of the actuator cylinder 710 to pass through. The diameter of the mounting hole 620 matches the diameter of the telescopic end of the actuator cylinder 710 so that the telescopic end of the actuator cylinder 710 can just pass through the mounting hole 620. The mounting hole 620 plays a guiding and limiting role for the telescopic end of the actuator cylinder 710. The pressure sensor 900 is located in the mounting cylinder 610. The main function of the mounting cylinder 610 is to install the pressure sensor 900.

[0043] Reference Figure 2 and Figure 3 As shown, it can be understood that an upper connecting block 611 and a lower connecting block 612 are also provided in the installation cylinder 610, and the pressure sensor 900 is located between the upper connecting block 611 and the lower connecting block 612. The upper connecting block 611 is threadedly connected to the telescopic end of the actuator cylinder 710, and the lower end of the upper connecting block 611 abuts against the pressure sensor 900, and the diameter of the upper connecting block 611 is larger than the diameter of the installation hole 620. When the telescopic end of the actuator cylinder 710 moves upward, it will drive the upper connecting block 611 to move upward, thereby pulling the installation cylinder 610 to move upward. The diameters of the upper connecting block 611 and the lower connecting block 612 match the diameter of the inner wall of the installation cylinder 610, which plays a guiding role, so that the pressure sensor 900 is only subjected to the force in the up and down directions, thereby improving the measurement accuracy.

[0044] Reference Figure 2 and Figure 3 As shown, it can be understood that the guide rod 200 is sleeved with a flange linear bearing 220, which passes through the pressing plate 600 and is bolted to the pressing plate 600. The flange linear bearing 220 guides to ensure that the pressing plate 600 can remain horizontal when moving up and down, thereby improving the quality of the pressed product.

[0045] Reference Figures 1 to 4 As shown, it can be understood that the frame 100 is also vertically connected with an infrared sensor 110, which is located at the front side of the guide rod 200. The infrared sensor 110 can detect human infrared signals and determine whether the operator has put his hand into the space above and below the pressing plate 600. When the infrared sensor 110 detects that the operator has put his hand into the space above and below the pressing plate 600, it will send a signal to stop supplying air to the execution cylinder 710. This prevents the operator's fingers from being pinched when the execution cylinder 710 is in motion.

[0046] Reference Figure 3 and Figure 4As shown, it can be understood that the support plate 400 and the pressing plate 600 are arranged in parallel. The support plate 400 and the pressing plate 600 always remain parallel to each other when moving. The parallel arrangement enables the pressing plate 600 to be evenly stressed when pressing the material 500.

[0047] Reference Figures 1 to 4 As shown, it can be understood that the upper end of the support plate 400 is connected to a lower die 410 whose shape matches the material 500, the material 500 is placed on the lower die 410, and the lower die 410 plays a role in positioning the material 500, and the lower end of the pressing plate 600 is connected to an upper die 630 that matches the material 500. The upper die 630 and the lower die 410 are both provided with grooves whose shapes match the material 500 for the material 500 to be embedded. Since the surface of the material 500 has an arc, the groove is used to disperse the pressure of pressing the material 500 to prevent stress concentration from damaging the material 500.

[0048] Usage steps: The operator places the material 500 on the pallet 400, and then the pushing device 300 drives the pallet 400 to move to the detection position. The visual inspection device 800 detects the material 500 on the pallet 400 to determine the assembly status of the parts in the shell on the pallet 400. If the parts in the shell on the pallet 400 are placed correctly, the pushing device 300 moves the pallet 400 to the pressing position, and the operator places the other part of the shell on the pallet, and the cylinder 710 drives the pressing plate 600 to move downward, and then the pressing plate 600 and the pallet 400 press the material 500. If the parts in the outer shell on the pallet 400 are not assembled and placed correctly, the pushing device 300 will not work, waiting for the operator to place the material 500 on the pallet 400 correctly, and then move the pallet 400 to the pressing position. The operator puts another part of the outer shell on the pallet, executes the cylinder 710 to drive the pressing plate 600 to move downward, and then the pressing plate 600 and the pallet 400 press the material 500.

[0049] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
