DETAILED DESCRIPTION

[0033] The following is combined with Figure 1 To Attachment Fig.16 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0034] The utility model is an automatic sharpening device for high-frequency scissors blades. The blades referred to in the utility model are as follows: Figure 1 and Figure 2 As shown, Figure 1 is a schematic diagram of the workpiece structure. Figure 2It is a schematic diagram of the structure of workpiece 2, workpiece 1 is a composite bending part 1, and workpiece 2 is a matching part 2.

[0035] A high-frequency scissors blade-sharpening automation equipment includes an operating table 100 and a divider 200 arranged on the operating table 100 and driven by a stepper motor. A first loading station 300, a second loading station 400, a blade-sharpening station 500 and a unloading station 600 are sequentially arranged on the operating table 100 along the periphery of the divider 200. The divider 200 is a disc-shaped device. A plurality of self-locking fixtures 700 for clamping workpieces are arranged near the edge of the divider 200. The positions of the self-locking fixtures 700 correspond to the positions of each station to ensure that each station works at the same time. In one embodiment, six groups of self-locking fixtures 700 are arranged. On the operating table 100, near the first loading station 300 and the second loading station 400, there are also a push device 800 for locking the self-locking fixture 700 and a positioning component 900 for positioning the workpiece. A slag discharge port 110 is also provided on the operating table 100 for discharging grinding waste slag.

[0036] like Figures 4 to 6As shown, the first loading station 300 is a loading station for the composite bending part 1, including a loading plate 310, a horizontal material channel 320, a first pushing assembly 330 and a rotating assembly 340. The horizontal material channel 320 is used to place the composite bending part 1. The horizontal material channel 320 is composed of two chrome-plated rods. In order to match the shape characteristics of the composite bending part 1, the two chrome-plated rods are set at different heights. A first slideway 311 parallel to the horizontal material channel 320 is provided on the loading plate 310. The horizontal material channel 320 is arranged above the first slideway 311. The first pushing assembly 330 is driven by a stepper motor and pushes the workpiece on the horizontal material channel 320 along the first slideway 311 to move toward the divider 200 for loading. To further improve the efficiency of loading, in one embodiment, two groups of horizontal material channels 320 are provided. Accordingly, two first slideways 311 are provided on the loading plate 310, and a connecting slideway 312 is provided at the ends of the same end of the two first slideways 311 to connect the two first slideways 311. A cylinder and a slide rail are provided next to the loading plate 310. The telescopic end of the cylinder is fixedly connected to the loading plate 310. The movement of the telescopic end of the cylinder drives the loading plate 310 to move along the slide rail, so that the first pushing assembly 330 is displaced with the loading plate 310 in the connecting slideway 312. The rotating assembly 340 includes a rotating arm 341 and a first suction cup 342 provided at the end of the rotating arm 341. The first suction cup 342 can absorb the workpiece on the horizontal material channel 320 and place the workpiece on the self-locking fixture 700 through the rotation of the rotating arm 341. In one embodiment, the rotating assembly 340 also includes a horizontal moving cylinder and a lifting cylinder, so that the rotating assembly 340 can move in the horizontal direction and the vertical direction, and the transportation is more flexible. At the two ends of the horizontal material channel 320, support 1 321 and support 2 322 are respectively arranged, support 1 321 is arranged at one end of the horizontal material channel 320 close to the rotating assembly 340, and support 2 322 is arranged at the other end. A steel ball 350 is arranged on support 1 321. When the workpiece is transported to the horizontal material channel 320 close to support 1 321, the steel ball 350 first contacts the workpiece, reducing the friction scratches of the workpiece and playing a role in protecting the workpiece. A vibrator 360 is arranged on support 2 322 to assist in loading by vibration to avoid the situation where the workpiece is not transported in place and the first suction cup 342 cannot grab it. In one embodiment, an inclined plate 370 can also be installed below the loading plate 310 to recover the workpiece dropped from the first slide 311.

[0037] like Figure 7 and Figure 8As shown, the second loading station 400 is a loading station for the matching part 2, including a vertical material channel 410, a slide 420 arranged below the vertical material channel 410, a second pushing assembly 430 and a transverse moving assembly 440. The vertical material channel 410 is composed of a plurality of positioning rods 411, and the plurality of positioning rods 411 are combined to form the shape of the matching part 2, so as to restrict the matching part 2 in the vertical material channel 410. The slide 420 is provided with a slide groove 421 and a second slide groove 422 arranged parallel to the slide groove 421. The workpiece falls into the slide groove 421 from the lower end outlet of the vertical material channel 410 by its own gravity. The height of the slide groove 421 is equivalent to or slightly greater than the thickness of the workpiece, so as to ensure that only one workpiece falls into the slide groove 421 at a time. The second pushing assembly 430 includes a push plate 431, which is driven by a cylinder and pushes the workpiece on the slide groove 421 along the second slide groove 422 to move toward the divider 200 for loading. A cylinder is also provided under the push plate 431 to drive it to rise and fall. After the push plate 431 pushes away the first workpiece, the second workpiece falls into the slide 421. When the push plate 431 completes loading and returns along the second slide 422, it must first be driven by the cylinder to descend by at least the thickness of one workpiece. When the push plate 431 returns to its initial position, it is driven by the cylinder to rise and reset, and continue to push the second workpiece to complete loading. A second suction cup 441 is provided on the transverse moving assembly 440. The second suction cup 441 is connected to a device that can suck the workpiece on the slide 421 and place the workpiece on the self-locking fixture 700. In one embodiment, the transverse moving assembly 440 also includes a horizontal moving cylinder and a lifting cylinder, so that the second suction cup 441 can move in the horizontal and vertical directions, making transportation more flexible.

[0038] like Figure 3 As shown, the sharpening station 500 includes a diamond grinding wheel 510, which can grind and sharpen the workpiece on the self-locking fixture 700. The driving mode of the diamond grinding wheel 510 can be selected from the common driving modes in the prior art, such as motors, belt drives, etc. The sharpening station 500 also includes a grinding assembly 530 for causing the diamond grinding wheel 510 to move axially. In one embodiment, the grinding assembly 530 can be a cylinder and a slide rail. The cylinder drives the diamond grinding wheel 510 to move axially on the slide rail, which can achieve one-knife grinding without repeated grinding, thereby improving work efficiency. Since the diamond grinding wheel 510 may wear the workpiece after processing a certain number of workpieces, in one embodiment, the sharpening station 500 also includes a grinding wheel 520, which is driven by a motor and matched with a specific rotation speed to achieve online grinding.

[0039] like Figures 12 to 15As shown, the self-locking clamp 700 includes a pressure plate assembly 710 and a positioning assembly 720. The pressure plate assembly 710 includes a pressure plate 1 711, a pressure plate 2 712 and a base 713. One end of the pressure plate 1 711 is in contact with one end of the pressure plate 2 712, and the contact position is defined as a contact point. A groove 714 is provided in the base 713, and the pressure plate 1 711 and the pressure plate 2 712 are arranged in the groove 714 and are movably connected to the base 713 through a rotating shaft 1 716 and a rotating shaft 2 717 respectively. A tension spring 715 is also provided between the pressure plate 1 711 and the base 713 to maintain the opening state of the pressure plate 1 711. Specifically, one end of the tension spring 715 is provided between the rotating shaft 1 716 and the contact point, and the other end of the tension spring 715 is provided at a position close to the bottom of the base 713. A pin can be provided at the bottom of the base 713 to hang the tension spring 715. The positioning assembly 720 includes a positioning seat 721 and positioning protrusions 722 arranged on the positioning seat 721. The workpiece is placed on the positioning seat 721 and is limited by a plurality of positioning protrusions 722. In order to further improve work efficiency, in one embodiment, each set of self-locking clamps 700 is provided with two sets of pressure plate assemblies 710. Accordingly, on the positioning assembly 720, a plurality of positioning protrusions 722 are divided into two groups, namely position one and position two. Position one is used to place the composite bending part 1, and position two is used to place the matching part 2. In this way, the two workpieces can be limited at the same time. In order to adapt to the shape of the composite bending part 1, a positioning groove 723 can be opened at the corresponding position of position one.

[0040] like Fig.10 As shown, the push device 800 includes a horizontal track 810 and a locking cylinder 820. The two ends of the horizontal track 810 are fixed to the operating table 100 through two columns respectively. The locking cylinder 820 is arranged on the horizontal track 810 and can slide on the horizontal track 810. The telescopic end of the locking cylinder 820 can contact or separate with the push portion 719 of the second pressing plate 712. In one embodiment, two groups of locking cylinders 820 are provided, and the setting positions correspond to the first loading station 300 and the second loading station 400 respectively.

[0041] like Fig. 9 and Fig.10As shown, the unloading station 600 includes an unlocking cylinder 610, a unloading assembly 620 and a conveyor belt 630. The unlocking cylinder 610 is arranged on the operating table 100 and below the divider 200. The telescopic end of the unlocking cylinder 610 can contact or separate with the push portion 719 of the second pressing plate 712. In one embodiment, two sets of unlocking cylinders 610 are provided. When the self-locking fixture 700 carries the processed workpiece to the unloading station 600, the telescopic end of the unlocking cylinder 610 extends out, passes upward through the circular hole provided on the divider 200 and pushes against the push portion 719 of the second pressing plate 712, so that the self-locking fixture 700 is unlocked, the first pressing plate 711 is opened, and the unloading assembly 620 is provided with a unloading suction cup 621, which can suck the workpiece from the self-locking fixture 700 and place the workpiece on the conveyor belt 630. The conveyor belt 630 rotates under the drive of the motor to complete the unloading. In one embodiment, the unloading assembly 620 also includes a horizontal moving cylinder and a lifting cylinder, so that the unloading suction cup 621 can move in the horizontal direction and the vertical direction, making the unloading more flexible.

[0042] The contact surface 718 between the second pressing plate 712 and the first pressing plate 711 is designed as a special-shaped arc surface, similar to the surface of a cam. When loading, after the workpiece is placed on the positioning seat 721, the telescopic end of the locking cylinder 820 pushes the push portion 719 downward to move downward, and the contact ends of the first pressing plate 711 and the second pressing plate 712 move relative to each other, and the contact surface 718 of the special-shaped arc surface is used to make the first pressing plate 711 and the second pressing plate 712 complete the self-locking state. At this time, the workpiece is firmly pressed on the positioning seat 721 by the first pressing plate 711, and the tension spring 715 is in a stretched state at this time; when unloading, the telescopic end of the unlocking cylinder 610 pushes the push portion 719 upward to move upward, so that the first pressing plate 711 and the second pressing plate 712 are unlocked. At this time, the tension spring 715 is reset, the first pressing plate 711 is opened, the workpiece is released, and the unloading suction cup 621 absorbs the workpiece and places the workpiece on the conveyor belt 630.

[0043] like Fig.16 As shown, the alignment component 900 includes a bracket 910, a push rod 920 and a push head 930. In one embodiment, the alignment component 900 is provided with two groups, which are respectively arranged near the first loading station 300 and the second loading station 400. The bracket 910 is arranged on the operating table 100, the push rod 920 is arranged on the bracket 910 and is slidably connected with the bracket 910 through a cylinder and a slide rail, and the push head 930 is arranged at the end of the push rod 920. When the workpiece is placed on the positioning seat 721, the position may be inaccurate. The push head 930 can push the workpiece on the positioning seat 721 under the drive of the push rod 920 to align the workpiece. In one embodiment, two push heads 930 are provided to align the workpiece from two different directions.

[0044] The working process of the utility model is now described with an embodiment:

[0045] A group of composite bending parts 1 are placed on two horizontal material channels 320. Driven by the stepper motor, the first push assembly 330 pushes the composite bending parts 1 on the first horizontal material channel 320 to move. When the composite bending parts 1 move to the end of the horizontal material channel 320 and are limited by the steel ball 350, the first suction cup 342 descends to absorb the composite bending parts 1 and places them on position 1 of the positioning seat 721 through ascending, lateral movement and rotation. When all the composite bending parts 1 on the first horizontal material channel 320 are loaded, the cylinder drives the loading plate 310 to move, so that the first push assembly 330 moves along the connecting slide 312 to the second horizontal material channel 320, and continues to push the composite bending parts 1 on the horizontal material channel 320 to load. At this time, a new group of composite bending parts 1 can be placed on the first horizontal material channel 320 to wait for loading. When the composite bending part 1 is placed on position 1 of the positioning seat 721, the push head 930 is pushed by the push rod 920 to approach the composite bending part 1 to align it. After the alignment is completed, the push rod 920 drives the push head 930 back to its original position. At this time, the telescopic end of the locking cylinder 820 pushes the push part 719 downward, and the pressing plate 1 711 and the pressing plate 2 712 are locked. The pressing plate 1 711 firmly presses the composite bending part 1 on position 1 of the positioning seat 721. The stepper motor drives the divider 200 to rotate, so that the self-locking clamp 700 comes to the second loading station 400. Prior to this, a group of mating parts 2 are placed in the vertical material channel 410. Driven by the cylinder, the second pushing assembly 430 pushes the mating part 2 on the slide groove 421 along the second slide 422 to move. When it moves to the end of the slide seat 420, the second suction cup 441 descends to absorb the mating part 2 through the ascending and lateral movements, and places it on the second position of the positioning seat 721. Similar to the composite bending part 1, at this time, the push head 930 of another group of alignment assemblies 900 approaches the mating part 2 to align it under the push of the push rod 920. After the alignment is completed, similarly, the telescopic end of the locking cylinder 820 pushes down the push part 719 of the other group of pressure plates 712, and the pressure plates 1 711 and 712 are locked. The pressure plate 1 711 firmly presses the mating part 2 on the second position of the positioning seat 721. The stepper motor continues to drive the divider 200 to rotate, so that the self-locking fixture 700 comes to the sharpening station 500, and the diamond grinding wheel 510 grinds the workpieces at position one and position two respectively, and moves axially on the cylinder-driven download slide rail to complete the one-knife grinding. The stepper motor continues to drive the divider 200 to rotate, so that the self-locking fixture 700 comes to the unloading station 600, and the telescopic ends of the two sets of unlocking cylinders 610 simultaneously push the push parts 719 of the two sets of pressing plates 712 upward to move upward, so that the pressing plates 1 711 and 2 712 are unlocked, and the unloading suction cup 621 sucks the workpiece and places the workpiece on the conveyor belt 630 to complete the unloading. The self-locking fixture 700 is provided with several groups corresponding to the positions of each station, and the above-mentioned loading, sharpening and unloading processes can be carried out simultaneously, which improves work efficiency.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
