Description

Technical Field

[0001] This utility model belongs to the technical field of decorative mirror assembly line, and in particular relates to a lens transfer platform based on a decorative mirror assembly line. Background Technology

[0002] With the upgrading of consumption and the increasing demand for home aesthetics, solid wood decorative mirrors are in growing market demand due to their unique texture and elegant style. One of the key processes in their production is to precisely assemble the glass lens into the solid wood frame. This requires that the gap between the glass and the frame be uniform and symmetrical, and the error usually needs to be controlled at the millimeter or even sub-millimeter level in order to achieve a high-quality appearance.

[0003] Currently, the industry is gradually adopting industrial robots to replace manual labor for glass handling and framing. A typical approach involves robots using vacuum suction cups to pick up glass from glass racks, directly transporting it and placing it into wooden frames for assembly. However, this method has many inherent drawbacks: 1. Insufficient precision: The absolute positioning accuracy of the robot, the installation deviation of the glass on the suction cup, and the placement error of the wooden frame itself will add up to each other, causing the final assembly error to exceed the allowable range. Although a high-precision six-axis robot can improve the accuracy, the cost is extremely high, and it is still difficult to overcome all the accumulated errors.

[0004] 2. Large-size glass is easily damaged: Common full-length mirrors have large glass sizes, heavy weights, and brittle materials. During the handling process by the robot, the glass is only supported by a few suction cups and is in a suspended state for a large area. Under its own weight, it is easy to deform. This deformation not only affects the accuracy of visual positioning, but also easily causes the glass to break due to stress concentration during movement or placement, resulting in production accidents and economic losses.

[0005] Therefore, there is an urgent need in this field for an intelligent glass assembly turntable that can achieve high-precision frame assembly and ensure the safe handling of large-size glass, in order to solve the aforementioned technical problems. Summary of the Invention

[0006] The purpose of this utility model is to provide a lens transfer platform based on a decorative mirror assembly line. Through the design of the transfer platform, an industrial robot performs rapid coarse positioning, moves the glass to the transfer platform, and then the XYθ precision positioning platform performs fine positioning. This eliminates all cumulative errors such as robot absolute accuracy and placement deviation, overcomes the shortcomings of the existing technology that relies on the insufficient positioning accuracy of a single robot, and ensures that the assembly accuracy can reach the micron level, which is far higher than the industry standard, thus ensuring the high-quality appearance of the product.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a lens transfer platform based on a decorative mirror assembly line, including a main frame, an adsorption platform and two extended support platforms. The main platform is fixed to the top of the main frame by an XYθ precision positioning platform. Plate-type main LED backlights are fixed on both sides of the top of the main platform. The adsorption platform is set between the two main LED backlights. The upper surface of the main LED backlights is flush with the upper surface of the vacuum adsorption platform. The two extended support platforms are symmetrically arranged on the front and rear sides of the main frame. Each extended support platform includes a vertical frame, and a secondary platform is rotatably connected to the top of the vertical frame. Two tilting cylinders are provided between the secondary platform and the bottom of the vertical frame. A secondary LED backlight is fixed on both sides of the top of the secondary platform. A mounting platform is provided between the two secondary LED backlights. Several universal balls are fixed on the upper surface of the mounting platform. The apex of the universal balls is higher than the upper surface of the secondary LED backlight, with a difference of 5-10mm. When the secondary platform is horizontal, the apex of the universal ball is flush with the upper surface of the adsorption platform. The main frame is equipped with hangers at both the front and rear ends on one side, and CCD industrial cameras facing the front and rear ends of the adsorption stage are fixed on the hangers.

[0008] Furthermore, a rotation clearance interval is formed between the secondary platform and the main platform, and between the hanger and the main platform, and a robot clearance space is formed between the CCD industrial camera and the adsorption table.

[0009] Furthermore, it also includes a control system, which is connected to an image processing and computing module. The adsorption stage, CCD industrial camera, and XYθ precision positioning platform are all electrically connected to the control system.

[0010] Furthermore, the XYθ precision positioning platform consists of an X-axis linear module, a Y-axis linear module, and an θ-axis rotary module stacked sequentially from bottom to top, with the main platform mounted on the θ-axis rotary module.

[0011] Furthermore, an annular frame is fixed at the bottom of the main platform and surrounds the θ-axis rotating module. A rectangular frame is provided at the bottom edge of the main platform, and several ribs are provided between the rectangular frame and the annular frame.

[0012] Furthermore, the tilting cylinder is a multi-stage cylinder, and both ends of the tilting cylinder are rotatably connected to the vertical frame and the auxiliary platform through hinge seats.

[0013] This utility model has the following beneficial effects: 1. This utility model, through the design of a transfer platform, enables an industrial robot to perform rapid coarse positioning, moving the glass to the transfer platform, where the XYθ precision positioning platform then performs fine positioning. This eliminates all cumulative errors such as robot absolute accuracy and placement deviation, overcoming the shortcomings of existing technologies that rely on insufficient robot single positioning accuracy. It ensures that the assembly accuracy can reach the micron level, far exceeding industry standards, thus ensuring the high-quality appearance of the product.

[0014] 2. This utility model, through the design of the main adsorption platform and the extended support platform, can meet the needs of large-size glass. The glass is always stably supported on a complete plane, eliminating gravitational deformation and thus avoiding the risk of positioning inaccuracy and stress cracking caused by it. At the same time, it reduces the load on the XYθ precision positioning platform, ensuring accuracy while improving safety.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The adsorption platform 2 is set between the two main LED backlights 501, and the upper surface of the main LED backlight 501 is flush with the upper surface of the vacuum adsorption platform 2. Two extended support platforms 3 are symmetrically arranged on the front and rear sides of the main frame 1. The extended support platform 3 includes a vertical frame 301. A secondary platform 302 is rotatably connected to the top of the vertical frame 301. Two tilting cylinders 303 are provided between the secondary platform 302 and the bottom of the vertical frame 301. A secondary LED backlight 304 is fixed on both sides of the top of the secondary platform 302. A mounting platform 305 is provided between the two secondary LED backlights 304. Several universal balls 306 are fixed on the upper surface of the mounting platform 305. The apex of the universal balls 306 is higher than the upper surface of the secondary LED backlights 304, with a difference of 5-10mm. When the secondary platform 302 is in a horizontal state, the apex of the universal ball 306 is flush with the upper surface of the adsorption platform 2. The main frame 1 has a hanger 6 at both the front and rear ends on one side, and a CCD industrial camera 601 is fixed on the hanger 6 facing the front and rear ends of the adsorption stage 2.

[0020] Among them, such as Figure 1 As shown, a rotation clearance interval is formed between the secondary platform 302 and the main platform 5, and between the hanger 6 and the main platform 5. A robot clearance space is formed between the CCD industrial camera 601 and the adsorption stage 2.

[0021] It also includes a control system, which is connected to an image processing and computing module. The adsorption stage 2, the CCD industrial camera 601, and the XYθ precision positioning platform 4 are all electrically connected to the control system.

[0022] Among them, such as Figure 2 As shown, the XYθ precision positioning platform 4 consists of an X-axis linear module 401, a Y-axis linear module 402, and an θ-axis rotary module 403 stacked sequentially from bottom to top, with the main platform 5 mounted on the θ-axis rotary module 403.

[0023] Among them, such as Figure 2 As shown, the bottom of the main platform 5 is fixed with an annular frame 502 surrounding the θ-axis rotating module 403, and a rectangular frame 503 is provided at the bottom edge of the main platform 5. Several ribs 504 are provided between the rectangular frame 503 and the annular frame 502.

[0024] Among them, the tilting cylinder 303 is a multi-stage cylinder, and the two ends of the tilting cylinder 303 are rotatably connected to the vertical frame 301 and the auxiliary platform 302 through hinge seats.

[0025] The working principle of this utility model is as follows: A robot drives an adsorption arm to move the glass from the glass holder to the adsorption table 2 and the main LED backlight 501 on the main table 5. The glass is adsorbed and fixed by the adsorption table 2, and the glass is in a coarse positioning state. The light emitted by the main LED backlight 501, combined with the opaque nature of the back of the glass, allows the CCD industrial camera 601 to capture the edges and corners of the glass. After analysis and calculation by the control system, the position of the main table 5 is controlled by the XYθ precision positioning platform 4, and the glass moves with the main table 5 for fine position adjustment and positioning. After the positioning adjustment is completed, the robot drives the adsorption arm to transfer the glass to the lens mounting station. During this period, after the adsorption arm adsorbs the glass, the adsorption of the adsorption table 2 is released, and then the robot transfers the material.

[0026] When the decorative mirror to be assembled is large or long, such as a full-length mirror, the secondary table 302 is flipped to a horizontal state by the flipping cylinder 303 before the transfer. When the glass moves to the adsorption table 2, the two ends of the glass are supported by universal ball bearings 306 respectively, and the secondary LED backlight 304 supplements the light source. The glass specifications are input into the host computer or human-machine interface, and different visual parameters (such as ROI area) pre-stored in the control system are called accordingly to ensure the capture of the CCD industrial camera 601.
