DETAILED DESCRIPTION

[0027] The present invention will be described in further detail below with reference to the accompanying drawings. The following embodiments are provided to explain the present invention, but the present invention is not limited to the following embodiments.

[0028] like Figure 1 As shown, the utility model is an embodiment of an automatic swinging machine suitable for medium and large optical glass blocks, which is used for automatic swinging of optical glass blocks in the secondary molding process of optical glass. It consists of four parts: a feeding device 1, a movable slide 2, a swinging device 3 and an electrical control box 4. Among them, the feeding device 1 includes a rotator 101, the swinging device 3 is installed on the movable slide 2, a slide bracket 207 is provided at the bottom of the movable slide 2, a retaining ring lower base plate 306 is provided at the bottom of the swinging device 3, and the electrical control box 4 is equipped with an electrical control system and a pneumatic control system.

[0029] like Figure 2 As shown, the vibrator 101 of the feeding device 1 is of a spiral progressive type and is placed on the base plate 102. The vibrating disk 103 is installed at the center of the vibrating disk 101. A certain amount of scattered optical glass blocks 105 are placed in the vibrating disk 103. The vibrating disk 103 can adjust the placement of the blocks on the slide according to the size of the optical glass blocks 105, screen and remove overlapping optical glass blocks 105, and ensure that the optical glass blocks 105 enter the discharge port in a fixed posture. When the vibrating disk 103 is manufactured, sufficient depth is reserved. During the feeding process, special powders and spherical resins can be placed in the vibrating disk 103 together with the optical glass blocks 105, eliminating the need for manual powder application and adopting the method of rotating the powder application in the vibrating disk 103. A retaining ring 104 is welded at the discharge port of the vibrating disk 103, and the upper edge of the retaining ring 104 is lower than the discharge port. The limiting retaining ring 104 can prevent the optical glass block 105 from falling beyond the projected position below the retaining ring 104 , so that the optical glass block 105 can be correctly positioned.

[0030] like Figure 3 As shown, the mobile slide 2 includes a slide module 206 and a servo motor 201, a rear limit photoelectric sensor 202, an origin photoelectric sensor 203 and a front limit photoelectric sensor 205 installed on the slide module 206, and is installed above the flowing porcelain box. Among them, the slide module 206 is fixed on the slide bracket 207, and the input end of the slide module 206 is connected to the servo motor 201. The slide module 206 is installed above the flowing high-temperature porcelain box and maintains a certain height to prevent high temperature from damaging the equipment. The output shaft of the servo motor 201 is installed in the coupling of the screw module and is connected through the nut of the flange to fix the servo motor 201. The electrical system and program control drive the swing device 3 for precise positioning.

[0031] Furthermore, with servo motor 201 as a reference, a rear limit photoelectric sensor 202, an origin photoelectric sensor 203, and a front limit photoelectric sensor 205 are installed on slide module 206, starting from near and moving forward. Rear limit photoelectric sensors 202 and 205 prevent the swing mechanism from exceeding its range of motion. The origin photoelectric sensor ensures that the machine can find its mechanical origin after a power outage or restart.

[0032] Furthermore, a swing device bracket 204 is mounted on the slider of the slide module 206, and a diffuse reflection photoelectric switch 209 is installed at the discharge port via a sensor bracket 208 to accurately detect the optical glass blocks at the discharge port. Diffuse reflection photoelectric switch 209 is a diffuse reflection type photoelectric sensor that detects both the presence and absence of objects. It can accurately detect each falling optical glass block and transmit the signal to the control system.

[0033] like Figure 4 As shown, the swing device 3 consists of a lower push cylinder, a horizontal push cylinder, and a material receiving device, including cylinder 1 301, cylinder 2 302, cylinder pad 303, swing device bracket 204, material receiving tray 305, and retaining ring lower base 306. The swing device bracket 204 is fixed to the slider of the slide module 206, cylinder 1 301 is fixed to the swing device bracket 204, cylinder 2 302 is fixed to the material receiving tray 305, the piston rods of cylinders 1 301 and 2 302 are connected to the cylinder pad 303, the retaining ring lower base 306 is fixed to the cylinder pad 302, and the upper part of the retaining ring lower base 306 is covered with an elastic rubber strip 304. The swing device 3 is mounted on the slide of the screw, and as the slide moves, the entire swing device 3 moves. The cylinder 1 301 lowers the material holding device to a position close to the porcelain box, and then the cylinder 2 302 pushes the material holding device out, and finally the optical glass block falls into the pit of the porcelain box.

[0034] Further, such as Figure 4 He Ru Figure 5 As shown, the material tray 305 is fixed to the cylinder 2 302 by screws.

[0035] Furthermore, the lower base plate 306 of the retaining ring is fixed on the cylinder pad 302 through the mounting hole to prevent the optical glass block 105 from being damaged during the falling process. Figure 6 As shown, the elastic rubber strip 304 covers and fixes the upper portion of the retaining ring lower base plate 306 .

[0036] like Figure 7 As shown, the electrical control system includes a touch screen, a programmable controller, a servo driver, relay 1, relay 2, relay 3, solenoid valve 1, solenoid valve 2, and a vibration controller. The touch screen is electrically connected to the programmable controller and to the servo driver, relay 1, relay 2, and relay 3. The servo driver is electrically connected to the servo motor 201, relay 1 is electrically connected to solenoid valve 1, relay 2 is electrically connected to solenoid valve 2, relay 3 is electrically connected to the vibration controller, and the vibration controller is electrically connected to the vibrator 101. After the control logic is programmed and configured with the touch screen, the programmable controller and touch screen jointly control the electrical components. The programmable controller in the electrical control box 4 is connected to the touch screen for data exchange. The origin photoelectric sensor 203 and the diffuse reflection off switch 209 are electrically connected to the programmable controller and transmit signals to the programmable controller. The vibration controller adjusts the start and stop and output power of the vibrator 101.

[0037] like Figure 8 As shown, the pneumatic control system includes cylinder solenoid valve 1 and cylinder solenoid valve 2. Compressed air enters cylinder solenoid valve 1 and cylinder solenoid valve 2 at their intake ends. Cylinder solenoid valve 1 and cylinder 1 (301), and cylinder solenoid valve 2 and cylinder 2 (302) are connected by air pipes. Under the control of the electrical control system, cylinder solenoid valve 1 and cylinder solenoid valve 2 switch the compressed air in cylinder 1 (301) and cylinder 2 (302) according to control requirements, completing the corresponding cylinder movements.

[0038] When the vibrating plate 103 is filled with optical glass blocks 105, the automatic swinging machine is started. Through the vibration of the vibrator 101, the optical glass blocks 105 in the vibrating plate 103 slide along the track of the vibrating plate 103. After screening, the vibrating plate 103 discharges the optical glass blocks 105 one by one at the discharge port of the vibrating plate 103. Signal detection is performed at the discharge port. Through the cooperation of the movable slide 2, the material receiving device is positioned according to the specified position to ensure that the optical glass blocks 105 are placed in the corresponding hole. When each hole is filled with optical glass blocks 105, the signal of the empty mobile porcelain box is received after waiting. Then, the action of the cylinder is coordinated to place the optical glass blocks 105 in the empty porcelain box, completing one swinging action.
