Description

Technical Field

[0001] The utility model relates to spectacle lens production equipment, in particular to spectacle lens feeding equipment. Background Art

[0002] The lenses produced need to be sorted and packaged before they are put into storage or sold. In the early days, automatic packaging machines were used for packaging. However, automatic packaging machines generally use manual single-piece loading. The lenses in the lens tray are taken out one by one and placed on the feeding belt of the automatic packaging machine. A lens tray can generally only store 24 or 30 lenses. After a lens tray has been taken out, it is necessary to remove the empty lens tray and replace the lens tray. Due to the large daily output of lenses, in order to ensure the output of the automatic packaging machine, the speed of manual loading must be fast enough. It is labor-intensive for one worker to operate an automatic packaging machine. If the worker leaves for something in the middle of the process, the packaging machine will be forced to stop.

[0003] CN209410454U discloses an automatic lens feeding device, including a frame, a control system, a tray loading device, a tray loading manipulator, and a lens loading assembly, wherein the tray loading manipulator transfers the lens tray from the tray loading device to the tray conveying assembly, the tray loading manipulator is located above the tray loading device, and the tray loading manipulator includes a first driver, a second driver, a module, an anti-skid pad, a slider plate, a guide shaft, a clamping bracket, a linear sleeve, a third driver, a clamping fixed plate, and a connecting plate, the first driver drives the slider plate through the module, the slider plate is provided with a second driver, and the second driver is connected to the third driver; the anti-skid pad is installed on the clamping bracket and is connected to one end of the guide shaft at the same time, the other end of the guide shaft is connected to the third driver through the shaft connecting plate, the guide shaft is sleeved with a linear sleeve, and the linear sleeve is fixed on the clamping fixed plate; the anti-skid pad, guide shaft and linear sleeve are all four pieces, and the clamping bracket, clamping fixed plate and shaft connecting plate are all two pieces.

[0004] For the above-mentioned tray loading robot, after the tray loading robot clamps and lifts the lens tray, it needs to release the lens tray to the tray conveying assembly (belt conveying mechanism), and the tray conveying assembly conveys the lens tray to the bottom of the lens loading assembly. After the lens loading is completed by the lens loading assembly, the tray conveying assembly transports the lens tray to the tray unloading device.

[0005] From the above, it can be seen that the above-mentioned automatic lens feeding device requires the cooperation of the tray loading robot and the tray conveying assembly when loading the tray, and requires the cooperation of the tray unloading robot and the tray conveying assembly when unloading the tray, and both the tray loading device and the tray unloading device protrude from the outside of the frame. Therefore, the above-mentioned automatic feeding device is not only complex in structure and large in size, but also high in cost. Utility Model Content

It also includes a translation linear drive and a clamping mechanism for clamping the tray.

[0010] Furthermore, the tray loading unit includes a first supporting unit, a first lifting drive, a first lifting platform, and a stopper for limiting the rear end of the tray.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figures 1 to 4 The eyeglass lens loading device of the present invention comprises a frame 1, a tray loading unit 2, a lens loading unit 3, a translation linear drive 4, and a clamping mechanism 5 for clamping the tray. Each part and the relationship between them are described in detail below.

[0023] The frame 1 is fixed by a plurality of profiles. The structure of the frame 1 in the utility model is basically the same as that in CN209410454U, that is, the frame 1 is provided with a loading area 11, a lens extraction area 12, and a unloading area 13. However, the frame 1 in the utility model is different from the frame in CN209410454U in that a support component 15 for mounting a translation linear drive 4 is provided on the upper part of the frame 1, and the support component 15 cooperates with the loading area 11, the lens extraction area 12, and the unloading area 13. A photoelectric switch C for detecting a tray A is provided on the frame 1.

[0024] The tray loading unit 2 cooperates with the loading area 11. In the present invention, the tray loading unit 2 includes a first support unit 21, a first lifting driver 22, a first lifting platform 23, and a stopper 24 for limiting the rear end of the tray A. The first lifting driver 22 is fixed to the first support unit 21, the first lifting driver 22 cooperates with the first lifting platform 23, and the stopper 24 is fixed to the first lifting platform 23. Through the action of the stopper 24, the position of the tray A can be corrected to prevent the tray A from colliding with the bracket 1 due to incorrect position during the rising process.

[0025] The utility model further comprises a tray unloading unit 6, which cooperates with the unloading area 13, and the translation linear drive 4 also cooperates with the unloading area 13. The structure of the tray unloading unit 6 is substantially the same as that of the tray loading unit 2, and will not be described in detail here.

[0026] The first support unit 21 is a plate-shaped component, the upper end and the lower end of the first support unit 21 are respectively fixed to the frame 1, the first lifting driver 22 is composed of an electric screw mechanism, a guide rod, and a sliding seat, the motor in the electric screw mechanism is fixed to the first support unit 21, the screw in the electric screw mechanism is fixed to the output end of the motor in the electric screw mechanism, the nut in the electric screw mechanism is threadedly connected to the screw in the electric screw mechanism, the nut in the electric screw mechanism is fixed to the first lifting platform 23, the guide rod is fixed to the first support unit 21, the sliding seat is slidably matched with the guide rod, and the sliding seat is fixed to the first lifting platform 23. When the first lifting driver 22 is working, it drives the first lifting platform 23 to rise or fall.

[0027] In the present invention, a correction plate 14 is provided in the loading area 11 for correcting the position of the left and right ends of the pallet A. The correction plate 14 is located on the left and right sides of the first lifting platform 23, and is arranged along the height direction of the frame. The upper and lower ends of the correction plate 14 are respectively fixed to the frame 1. When the pallet A is placed on the first lifting platform 23 and the pallet A is pushed, if the position of the pallet A is incorrect, the ends of the pallet A will collide with the correction plates 14 on the left and right sides. Therefore, only when the position of the pallet A is correct can the pallet A move smoothly along the first lifting platform 23 and finally form abutment with the stopper 24.

[0028] The lens loading unit 3 cooperates with the lens extraction area 12. The structure of the lens loading unit 3 is basically the same as the lens loading unit disclosed in CN209410454U, and will not be repeated here.

[0029] The translational linear drive 4 cooperates with the frame 1, and the translational linear drive 4 cooperates with the loading area 11 and the lens extraction area 12. In the utility model, the translational linear drive 4 includes a motor 40, a reducer 41, a first transmission shaft 42, a second transmission shaft 43, a first transmission mechanism 44, and a second transmission mechanism 45. The output end of the motor 40 is connected to the output end of the reducer 41. The reducer 41 has at least two output ends and is respectively connected to one end of the first transmission shaft 42 and the second transmission shaft 43. The other end of the first transmission shaft 42 is connected to the first transmission mechanism 44, and the other end of the second transmission shaft 43 is connected to the second transmission mechanism 45.

[0030] The motor 40 is an electric motor, and the reducer 41 is composed of a housing, an active bevel gear, a passive bevel gear, bearings, etc. There is one active bevel gear and two passive bevel gears. The active bevel gear and the passive bevel gear are respectively mounted on the housing through bearings. The active bevel gear is respectively meshed with the two passive bevel gears. The active bevel gear is connected to the output end of the electric motor, one of the passive bevel gears is connected to the first transmission shaft 42, and the other passive bevel gear is connected to the second transmission shaft 43.

[0031] The first transmission mechanism 44 and the second transmission mechanism 45 both include a guide rail 46, a synchronous wheel, a synchronous belt, and a slider 47. The guide rail 46 is fixed to the frame 1, and synchronous wheels are respectively installed at both ends of the guide rail 46. The synchronous belt and the synchronous wheel are flexibly matched. The slider 47 is fixed to the guide rail 46, and the slider 47 is connected to the synchronous belt.

[0032] The clamping mechanism 5 is fixed to the translation linear drive 4. In the present invention, the clamping mechanism 5 includes a clamping drive 51 and a clamping block 52. The clamping drive 51 can be a conventional linear drive such as a cylinder, a hydraulic cylinder, or an electric screw. In the present invention, the clamping drive 51 preferably uses a cylinder. The output end of the clamping drive 51 is fixed to the clamping block 52, and the clamping block 52 is used to clamp the pallet A. The clamping mechanism 5 also includes a connecting plate 53, which is fixed to the translation linear drive 4, and each connecting plate 53 is fixed to at least two clamping drives 51.

[0033] The working process of the utility model is as follows:

[0034] Place one or more trays A loaded with lenses on cart B, and push cart B into the loading area 11. At this time, the first lifting platform 23 is located below tray A, and the first lifting driver 22 works to drive tray A to rise. When tray A blocks the photoelectric switch C, tray A on the uppermost layer rises to its position, and the first lifting driver 22 stops working. At this time, the clamping driver 51 drives the clamping block 52 to clamp tray A, and the motor 40 works. The torque output by the motor 40 is output to the first transmission shaft 42 and the second transmission shaft 43 through the reduction gear box. The first transmission shaft 42 and the second transmission shaft 43 rotate, and the first transmission shaft 42 drives the synchronous wheel to rotate, and the synchronous wheel drives the synchronous belt to move, and the synchronous belt drives the sliding Block 47 moves linearly along the guide rail 46, so that the tray A clamped by the clamping mechanism 5 moves to the lens extraction area 12, and the lens loading unit 3 works to extract the lenses in the tray A and release them to the designated position (for example, the packaging station). Since there are multiple rows of lenses on the tray A, each row generally has 4 lenses. After each row of lenses is extracted, the translation linear drive 4 drives the clamping mechanism 5 to step one station, so that the next row of lenses on the tray A arrives directly below the working position of the lens loading unit 3, and this is repeated until all the lenses on the tray A are extracted. The translation linear drive 4 drives the clamping mechanism 5 to move with the empty tray A to the unloading area 13, and the tray A is received by the tray unloading unit 6.
