[0027] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Combination Figures 1 to 10 As shown, a wave washer feeding mechanism includes a horizontally arranged slitting device and a feeding device. The slitting device includes a vibrating feeding plate 1, a vibrating tray 2, and a slitting robot 3. The feeding device includes a feeding platform 5 and a feeding rack 6. The slitting robot 3 drives a pneumatic gripper 7 to reciprocate between the vibrating tray 2 and the feeding platform 5. The pneumatic gripper 7 is installed on the lifting screw 31 of the slitting robot 3 through a connecting device 8. The connecting device 8 includes a locking ring 81, a connecting block 82, and a mounting base 83 arranged in sequence. The locking ring 81 is located at the end of the lifting screw 31, and the pneumatic gripper 7 is installed on the mounting base 83.
[0029] In this technical solution, both the slitting device and the feeding device are set on the horizontal workbench or the horizontal platform of the production line. The specific structure of the workbench or production line is existing technology and will not be described in detail here. An external control device consisting of PLC, solenoid valve, relay, etc. is also set. The structure and principle of the control device are existing technology. The slitting robot and pneumatic gripper can be directly purchased as commercially available finished products. After the corrugated washer falls from the vibrating feeding plate into the vibrating tray, the slitting robot moves the pneumatic gripper to directly above the corrugated washer and moves the pneumatic gripper down through the lifting screw. The pneumatic gripper picks up the corrugated washer. The lifting screw drives the pneumatic gripper to rise. The slitting robot moves the pneumatic gripper to the feeding platform and places the corrugated washer on the feeding platform. The feeding rack takes out the corrugated washer and sends it to the installation position. This corrugated washer feeding mechanism has a simple structure and is used for automated feeding of corrugated washers, improving production efficiency.
[0030] For example, see Figures 1 to 3 As shown, the lifting screw 31 has a hollow structure with a built-in channel for the air pipe to pass through. The mounting base 83 is provided with a threaded through hole. One end of the threaded through hole is connected to the connector of the pneumatic gripper 7, and the other end is connected to the quick connector 84. The connecting block 82 is provided with a clearance through hole corresponding to the quick connector 84 and is connected to the channel.
[0031] In this technical solution, the lifting screw, locking ring, connecting block, and mounting base are coaxially arranged. The locking ring directly utilizes existing locking ring / optical axis locking device / optical axis fixing ring and other structures, and is fixed to the outer wall of the end of the lifting screw (near the bottom of the vibrating tray). The connecting block is installed by conventional bolts. The center of the mounting base has a threaded through hole machined along its axial direction, and a conventional quick connector is connected to one end near the lifting screw. After the air pipe inside the lifting screw is inserted into the quick connector, the mounting base is installed to the connecting block by conventional bolts. The center of the connecting block has an avoidance through hole machined along its axial direction to avoid interference with the air pipe and quick connector. The connector of the pneumatic gripper is connected to the other end of the threaded through hole (the end opposite to the quick connector). The air pipe and quick connector are both hidden inside to avoid interference or snagging from external devices during movement.
[0032] For example, see Figure 4 and Figure 5 As shown, the vibrating feeder 1 includes a vibrator 11 and a feeder 12. The feeder 12 has a discharge port near the vibrating tray and extends above the vibrating tray.
[0033] In this technical solution, the vibratory machine can be a standard linear feeder, and the feeding tray can be fixed to the vibratory machine with conventional bolts, etc., to feed the corrugated washers to the vibratory tray. The feeding tray is made of conventional sheet metal through sheet metal processing. The width of the end near the vibratory tray is narrowed to form a discharge port, which controls the outflow direction of the corrugated washers and prevents them from moving outside the vibratory tray. The width of the discharge port must be greater than the outer diameter of the corrugated washers.
[0034] For example, see Figure 4 and Figure 5 As shown, a height limiting plate 121 is provided above the discharge port, and a height limiting opening is formed between the plate and the bottom wall of the discharge port to accommodate a corrugated washer.
[0035] In this technical solution, the height limit plate is made of conventional thin metal sheet through sheet metal processing. Mounting ears are bent on both sides of the end opposite the discharge port. These mounting ears are connected to the side wall of the feeding tray via conventional connecting pins. The side wall of the feeding tray is machined with adjustment grooves corresponding to the mounting ears. Locking bolts connected to the mounting ears are installed in the adjustment grooves. Loosening the locking bolts allows adjustment of the height limit plate's installation angle, thus adjusting the height of the height limit opening to meet the feeding requirements of corrugated washers of different thicknesses. A toggle port is machined on the side of the feeding tray near the height limit opening. When a corrugated washer is blocked near the height limit opening, a metal rod / plate is inserted into the toggle port to agitate the corrugated washer, ensuring normal feeding of the washer.
[0036] For example, see Figure 1 and Figure 4 As shown, an image detection device 9 is installed directly above the vibrating tray 2.
[0037] In this technical solution, the structure and working principle of the image detection device / vision device are existing technologies. It is set directly above the vibrating tray using a conventional mounting bracket. The camera of the image detection device can mark the entire area inside the vibrating tray to mark the position of the wave-shaped washers falling into the vibrating tray, ensuring the accuracy of the material picking and positioning of the slicing robot. When there is partial overlap between adjacent wave-shaped washers, the vibrating tray is activated until the distance between adjacent wave-shaped washers meets the material picking requirements of the pneumatic gripper. The vibrating tray can directly utilize the structure described in the existing technology.
[0038] For example, see Figure 6 and Figure 7 As shown, the loading platform 5 includes a support base 51 and a placement platform 52 installed on the support base 51. Two parallel positioning pins 53 are provided in the placement platform 52. The positioning pins 53 slide elastically in the placement platform 52, and their tops protrude from the placement platform 52.
[0039] In this technical solution, the support base is used to install the placement platform. The placement platform is fixed to the top of the support base by conventional bolts, etc. The wave-shaped washer picked up by the pneumatic gripper is fitted onto the positioning pin to complete the positioning of the wave-shaped washer. The outer diameter of the positioning pin is smaller than the inner diameter of the wave-shaped washer when it is stationary.
[0040] For example, see Figure 6 and Figure 7 As shown, the placement platform 52 is provided with a stepped through hole corresponding to the positioning pin 53, including a small diameter section and a large diameter section. The positioning pin 53 slides in the small diameter section and has a limiting boss corresponding to the large diameter section. A return spring 54 is provided between the limiting boss and the support base 51.
[0041] In this technical solution, the diameter of the large-diameter section is larger than that of the small-diameter section. The limiting boss prevents the positioning pin from falling off the placement table. The return spring applies an upward force to the positioning pin, causing the top of the positioning pin to protrude from the top surface of the placement table, thereby positioning the wave-shaped washer from the pneumatic gripper. When the feeding pin feeds the material, it squeezes the return spring through the positioning pin, causing the positioning spring to retract into the stepped through hole. The feeding pin passes through the wave-shaped washer. After the feeding pin drives the wave-shaped washer away, the return spring drives the positioning pin to return to its original position.
[0042] For example, see Figure 1 and Figure 8 As shown, the loading rack 6 includes a movable frame 62 slidably mounted on the gantry frame 61 and a loading pin 64 slidably mounted on the movable frame 62 via a lifting cylinder 63.
[0043] In this technical solution, the gantry frame is a conventional structure and is equipped with a horizontal cylinder for driving the moving frame, thereby driving the feeding pin to reciprocate between the top of the positioning pin and the installation position of the corrugated washer, etc. The moving frame is slidably connected to the gantry frame via conventional guide rails. There are two lifting cylinders, each connected to a feeding pin. The two feeding pins are respectively set to correspond to the two positioning pins. The lifting cylinders drive the feeding pins to rise and fall vertically.
[0044] For example, see Figures 8 to 10 As shown, the feeding pin 64 is slidably connected to the movable frame 62 via the slide block 65, and is connected to the piston rod of the lifting cylinder 63.
[0045] In this technical solution, the slide block is slidably connected to the moving frame via a conventional guide rail and connected to the piston rod of the lifting cylinder. The lifting cylinder drives the slide block to rise and fall vertically, which in turn drives the feeding pin to rise and fall.
[0046] For example, see Figures 6 to 10 As shown, the slide block 65 is equipped with a stripping cylinder 66, and the push plate of the stripping cylinder 66 is connected to a stripping sleeve 67, which is slidably sleeved on the feeding pin 64.
[0047] In this technical solution, the inner ring of the corrugated washer is not a standard circle when it is stationary. After the feeding pin is inserted into the inner ring of the corrugated washer, part of the inner wall of the corrugated washer abuts against the outer wall of the feeding pin, and they are fixed together by the friction between the inner wall of the corrugated washer and the outer wall of the feeding pin. The bottom end of the feeding pin and the top end of the positioning pin are both conical structures to facilitate the insertion of the corrugated washer. A conventional metal proximity sensor is set on the side of the placement platform. Both the placement platform and the positioning pin are made of non-metallic materials such as nylon. When the metal feeding pin is inserted to the corresponding depth of the stepped through hole, the metal proximity sensor detects... The feeding pin ensures full contact between the feeding pin and the corrugated washer. The positioning pin can also be made of metal. When the conical surfaces of the feeding pin and the positioning pin enter the installation height of the metal proximity sensor, the sensing signal is lost, thereby determining the depth of the feeding pin entering the stepped through hole and ensuring full contact between the feeding pin and the corrugated washer. The outer wall of the stripping sleeve is recessed with an annular groove. The push plate of the stripping cylinder is connected to the stripping plate. The stripping plate has protruding claws that are locked in the annular groove. The stripping cylinder drives the stripping sleeve to slide along the axial direction of the feeding pin, pushing the corrugated washer out of the feeding pin.
[0048] In summary, the waveform gasket feeding mechanism of this utility model has a simple structure and is used for automated feeding of multiple waveform gaskets, improving production efficiency. The air pipe and quick connector are both hidden inside to avoid interference or snagging from external devices during movement.

[0050] The above description is only a specific embodiment of this application.
