Scanning center with automatic tray cleaning function

Abstract

This utility model discloses a scanning center instrument with automatic tray cleaning capability, comprising: a scanner body including a horizontal frame and a vertical frame fixedly connected to the rear end of the horizontal frame, wherein a tray for placing lenses is installed on the top of the horizontal frame; and an adsorption assembly including: a guide component fixedly installed inside the vertical frame. This utility model can trigger the adsorption assembly's continuous "rotational alignment - downward adsorption - upward removal" action by pushing the outer sleeve, quickly completing tray cleaning without requiring manual removal of lenses from the tray, reducing manual intervention steps and shortening the interval between single inspections. The movement path of the adsorption assembly is controlled by the cooperation between the track groove and the guide rod, with the arc segment controlling rotational alignment and the vertical segment controlling vertical adsorption, ensuring that the adsorption tray can be aligned with the lens for adsorption, eliminating the need for operators to directly contact the lens with their fingertips, fundamentally solving the problem of lens scratches and cracks caused by improper force control.

Description

Technical Field

[0001] This utility model relates to the field of lens manufacturing technology, and in particular to a scanning center instrument that can automatically clean the tray. Background Technology

[0002] In fields such as optical lens processing, eyeglass fitting, and precision optical testing, scanning center instruments are widely used in key processes such as lens center positioning, angle calibration, and curvature measurement.

[0003] Existing scanning centers typically include a tray for holding lenses and a scanning mechanism. After scanning a lens, the operator must manually remove it from the tray for subsequent processing or replacement. This method is not only inefficient, but if the force is not properly controlled, the friction between the fingertip and the lens surface may cause the lens edge to crack or the surface to be scratched. Therefore, a scanning center with an automatic tray cleaning function is proposed to solve this problem. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] Scanning centers with automatic tray cleaning capabilities include:

[0006] The scanner body includes a horizontal frame and a vertical frame fixedly connected to the rear end of the horizontal frame, and a tray for placing lenses is installed on the top of the horizontal frame.

[0007] The adsorption assembly includes: a guide member, which is fixedly installed inside the frame, and the guide member has a continuous track groove, the track groove including a connected arc segment and a vertical segment;

[0008] The fastener is fixedly installed on the upright frame;

[0009] The outer sleeve is slidably fitted onto the surface of the fixing member along the axial direction;

[0010] The connector is integrally formed and disposed on the side wall of the outer sleeve;

[0011] The pressing component is installed at the end of the connector away from the outer sleeve;

[0012] An adsorption plate is snapped into the bottom of the pressing element;

[0013] The guide rod is fixedly connected to the side wall of the outer sleeve and slidably fitted into the track groove;

[0014] The process involves placing the lens on a tray for scanning. After scanning, the outer sleeve is driven to move axially along the fixing member, causing the guide rod to slide along the track groove. When the guide rod slides within the arc-shaped section of the track groove, it causes the connecting member and the adsorption plate to rotate around the axis of the fixing member, bringing the adsorption plate directly above the tray. When the guide rod slides into the vertical section of the track groove, it causes the connecting member and the adsorption plate to move downward in a straight line, causing the adsorption plate to descend and adsorb the lens, thus completing the pickup of the lens from the tray.

[0015] As an improvement to the above technical solution, the fixing member includes a fixing rod fixedly connected to the horizontal frame and a fixing sleeve fixedly sleeved on the fixing rod. The top of the fixing rod extends to the outside of the fixing sleeve, and a section of the fixing rod extending to the outside of the fixing sleeve is slidably connected to the outer sleeve. A spring is installed between the outer sleeve and the fixing sleeve.

[0016] As an improvement to the above technical solution, the pressing component includes a fixing block that is fixedly inserted into the end of the connector away from the outer sleeve. The fixing block has a cavity inside. A pressing rod is slidably inserted into the fixing block. The bottom of the pressing rod extends into the cavity. A spring is wound around the surface of the pressing rod and a section outside the fixing block. The suction cup is engaged with the bottom of the fixing block.

[0017] As an improvement to the above technical solution, the top two sides of the adsorption plate are integrally formed with locking rods, the bottom of the fixing block is provided with a locking groove that matches the locking rods, the top of the adsorption plate is fixedly connected to an extension cylinder that matches the cavity, and the bottom of the pressing rod extends into the extension cylinder.

[0018] As an improvement to the above technical solution, the surface of the connector is integrally formed with protrusions.

[0019] The beneficial effects of this utility model are:

[0020] By pushing the outer sleeve, the adsorption component can be triggered to perform a series of actions: rotational alignment, descent adsorption, and upward displacement. This quickly completes tray cleaning without the need for manual removal of lenses from the tray, reducing manual intervention steps and shortening the interval between single inspections.

[0021] The movement path of the adsorption component is controlled by the cooperation between the track groove and the guide rod. The arc segment controls the rotational alignment, and the vertical segment controls the vertical adsorption, ensuring that the adsorption plate can be aligned with the lens for adsorption. This eliminates the need for operators to directly contact the lens with their fingertips, fundamentally solving the problem of lens scratches and cracks caused by improper force control.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Scanning centers with automatic tray cleaning capabilities include:

[0029] The scanner body 10 includes a horizontal frame and a vertical frame fixedly connected to the rear end of the horizontal frame. A tray 11 for placing lenses is installed on the top of the horizontal frame.

[0030] The adsorption assembly 20 includes: a guide 27, which is fixedly installed in the frame. The guide has a continuous track groove, which includes a connected arc segment 25 and a vertical segment 26.

[0031] The fastener is fixedly installed on the upright frame;

[0032] The outer sleeve 21 is slidably fitted onto the surface of the fixing member along the axial direction;

[0033] Connector 22 is integrally formed and disposed on the side wall of the outer sleeve 21;

[0034] The pressing member 23 is installed at the end of the connector 22 away from the outer sleeve 21;

[0035] The adsorption plate 29 is engaged with the bottom of the pressing member 23;

[0036] The guide rod 212 is fixedly connected to the side wall of the outer sleeve 21 and slidably fitted in the track groove;

[0037] The lens is placed on the tray 11 for scanning. After scanning, the outer sleeve 21 is driven to move along the axis of the fixing member, which drives the guide rod 212 to slide along the track groove. When the guide rod 212 slides in the arc section 25 of the track groove, it drives the connector 22 and the adsorption plate 29 to rotate around the axis of the fixing member, so that the adsorption plate 29 rotates to be directly above the tray 11. When the guide rod 212 slides into the vertical section 26 of the track groove, it drives the connector 22 and the adsorption plate 29 to move downward in a straight line, so that the adsorption plate 29 descends and adsorbs the lens, thus completing the pickup of the lens from the tray 11.

[0038] Specifically, the lens is placed on the tray 11 at the top of the horizontal frame. The scanner body 10 scans the lens. At this time, the adsorption assembly 20 is in its initial position (not directly above the tray 11), the guide rod 212 is at the initial end of the track groove, and the adsorption plate 29 is not in contact with the lens. After scanning, the outer sleeve 21 is manually pushed to slide. The shape of the track groove directly constrains the movement path of the guide rod 212, thereby controlling the movement of the entire adsorption assembly 20. When the guide rod 212 moves in the arc section 25 of the track groove, the arc trajectory forces the outer sleeve 21 to rotate around the axis of the fixing member through the guide rod 212. This, in turn, drives the pressing member 23 and the adsorption plate 29 at the bottom to rotate through the integrally formed connector 22. The adsorption plate 29 rotates to the tray 11. Directly above, after completing the "alignment" action, the guide rod 212 slides out of the arc section 25 and enters the vertical section 26 of the track groove. The vertical section track constrains the guide rod 212 to slide downwards only in the vertical direction. At this time, the outer sleeve 21 slides downwards along the axis of the fixing member, and drives the pressing member 23 and the suction plate 29 to move downwards in a straight line synchronously through the connecting member 22. The suction plate 29 descends to contact the lens on the tray 11 and uses negative pressure to adsorb the lens, thus completing the "pickup" of the lens. After the lens is adsorbed, the outer sleeve 21 is manually pushed to move in the opposite direction, and the guide rod 212 slides in the opposite direction along the track groove, passing through the vertical section 26 and the arc section 25 in sequence, driving the suction plate 29 to rise and rotate away from the tray 11. The lens on the tray 11 is removed, realizing the automatic cleaning of the tray.

[0039] In one embodiment, reference Figure 4The fixing component includes a fixing rod 210 fixedly connected to the horizontal frame and a fixing sleeve 28 fixedly sleeved on the fixing rod 210. The top of the fixing rod 210 extends to the outside of the fixing sleeve 28, and a section of the fixing rod 210 extending to the outside of the fixing sleeve 28 is slidably connected to the outer sleeve 21. A spring 211 is installed between the outer sleeve 21 and the fixing sleeve 28. The fixing rod 210 provides a guide reference for the axial sliding of the outer sleeve 21, ensuring that the outer sleeve 21 can only slide stably along the axial direction of the fixing rod 210 and avoids deviation. The fixing sleeve 28 is fixedly sleeved on the lower middle part of the fixing rod 210. The outer sleeve 21 has two functions: firstly, it limits the downward movement of the outer sleeve 21, and secondly, it provides a bottom support point for the second spring 211. The second spring 211 is in a naturally extended state. Under the action of the spring force, the outer sleeve 21 is located at the upper part of the fixed rod 210, that is, at the junction of the vertical section 26 and the arc section. When the outer sleeve 21 is manually moved downward along the axis of the fixed rod 210, the outer sleeve 21 compresses the second spring 211, and the second spring 211 stores elastic potential energy. After the lens is adsorbed, the outer sleeve 21 is released, and the second spring 211 releases the external force. The second spring 211 pushes the outer sleeve 21 to slide upward along the fixed rod 210 under the action of the vertical section 26.

[0040] In one embodiment, reference Figure 3 The pressing member 23 includes a fixing block 233 fixedly inserted into one end of the connector 22 away from the outer sleeve 21. The fixing block 233 has a cavity 234 inside. A pressing rod 232 is slidably inserted into the fixing block 233. The bottom of the pressing rod 232 extends into the cavity 234. A spring 231 is wound around the surface of the pressing rod 232 and a section outside the fixing block 233. The suction cup 29 is engaged with the bottom of the fixing block 233.

[0041] In one embodiment, reference Figure 3The top two sides of the adsorption plate 29 are integrally formed with locking rods 291. The bottom of the fixing block 233 is provided with a locking groove adapted to the locking rods 291. The top of the adsorption plate 29 is fixedly connected to an extension tube 292 adapted to the cavity 234. The bottom of the pressing rod 232 extends into the extension tube 292. When the spring 231 is in a naturally extended state, the pressing rod 232 is kept in an upward pressing state by the elastic force of the spring 231. Its bottom does not squeeze the inner wall of the extension tube 292, and does not affect the engagement of the adsorption plate 29 and the fixing block 233. When the adsorption plate After the lens is lifted and rotated to the designated position, when the lens needs to be removed, the operator presses down on the top of the pressing rod 232 to overcome the elastic force of the spring 231, causing the pressing rod 232 to slide down along the cavity 234 of the fixing block 233, directly squeezing the inner wall of the extension cylinder 292, and transmitting the thrust to the adsorption plate 29. After the adsorption plate 29 is pushed downward, the top locking rod 291 overcomes the locking force of the slot and disengages from the slot, realizing the separation of the adsorption plate 29 from the fixing block 233. The adsorption plate 29 after disengagement is placed in the designated position along with the lens for subsequent processing.

[0042] In one embodiment, reference Figure 2 The surface of the connector 22 is integrally formed with protrusions 24. The operator can press or push the protrusions 24 to indirectly drive the connector 22 and the outer sleeve 21 to slide along the axis of the fixed rod 210, thereby triggering the rotation and descent of the adsorption assembly 20.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
