Description

Technical Field

[0001] The present invention belongs to the technical field of automobile rearview mirrors, and in particular to an automobile rearview mirror EC lens laminating tool and a laminating method. Background Art

[0002] With the development of the automotive industry, the automatic anti-glare function of exterior rearview mirrors has become popular, and the demand for automatic anti-glare lenses has increased.

[0003] like Figures 3 to 5 As shown, the exterior mirror's electronic anti-glare lens (EC lens) consists of an ITO lens glass and a reflective lens glass, which are bonded together. The ITO lens glass is 1.2mm larger in circumference than the reflective lens glass. The two lenses are secured together using epoxy adhesive, which requires heating. After bonding, the lens must be transferred to a heated oven, which can cause misalignment during transfer. To address this, a temporary, quick fix is ​​required. Typically, UV adhesive is applied at two points, which cures quickly under ultraviolet light.

[0004] Therefore, when EC lenses are bonded, they need to be temporarily fixed with UV glue. However, in actual operation, if the ITO lens glass is above the reflective lens glass, the ultraviolet lamp needs to be irradiated from below, which is inconvenient to operate; if the reflective lens glass is above the ITO lens glass, the ITO lens glass will be blocked by the positioning structure of the reflective lens glass when placed, which is inconvenient to place and affects the efficiency of EC lens bonding. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a tool for laminating an EC lens assembly for an automobile rearview mirror, the purpose of which is to improve the efficiency of laminating EC lenses.

[0029] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0030] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower" and similar expressions used in this article are for illustrative purposes only.

[0031] It should be noted that, in the following embodiments, the "first" and "second" do not represent an absolute distinction in structure and / or function, nor do they represent a sequence of execution, but are merely for the convenience of description.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which the present invention pertains. The terminology used herein in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] like Figure 1 and Figure 2 As shown, the present invention provides a car rearview mirror EC lens assembly bonding tool, including a membrane 4 for placing an ITO lens glass 12, a sensing device for sending a trigger signal after the ITO lens glass 12 is placed, and a reflective lens positioning device arranged on the membrane 4 and used to position the reflective lens glass 11 placed on the ITO lens glass 12. After the sensing device sends a trigger signal, the reflective lens positioning device is in a working state capable of positioning the reflective lens glass 11.

[0034] Specifically, if Figure 1 and Figure 2 As shown, a positioning groove for accommodating the ITO lens glass 12 is provided on the fetal membrane 4, and a plurality of reflective lens positioning devices are provided. All reflective lens positioning devices are arranged circumferentially on the outside of the positioning groove, and the sensing device is also located on the outside of the positioning groove. All reflective lens positioning devices are located on the same side of the sensing device, and all reflective lens positioning devices operate simultaneously. By positioning the reflective lens glass 11 together through a plurality of reflective lens positioning devices, the reflective lens glass 11 can be reliably positioned on the ITO lens glass 12, thereby avoiding movement of the reflective lens glass 11 during glue dispensing, and improving the EC lens bonding efficiency and bonding effect.

[0035] like Figure 1 and Figure 2 As shown, the reflector lens positioning device includes a movably arranged positioning block 8, a first electromagnet 6, and a second electromagnet 7. The first electromagnet 6 and the second electromagnet 7 are arranged with the same poles facing each other. The second electromagnet 7 is arranged on the positioning block 8. After the first electromagnet 6 and the second electromagnet 7 are energized, the positioning block 8 moves to a position close to the reflector lens glass 11 to position the reflector lens glass 11. The fetal membrane 4 is arranged horizontally, and the positioning block 8 is movably arranged on the fetal membrane 4. The fetal membrane 4 is provided with a guide groove for accommodating the positioning block 8. The movement direction of the positioning block 8 is horizontal. The first electromagnet 6 is fixedly arranged on the fetal membrane 4, and the second electromagnet 7 is fixedly arranged on the positioning block 8. The first electromagnet 6 and the second electromagnet 7 are arranged relative to each other, and the second electromagnet 7 is located between the first electromagnet 6 and the positioning groove. After the first electromagnet 6 and the second electromagnet 7 are energized, the positioning block 8 extends from the guide groove under the action of the repulsive force of the same magnetic poles, and the positioning block 8 moves toward the positioning groove. Finally, the positioning block 8 moves to the positioning position, and the positioning block 8 approaches the reflective lens glass 11 to position the reflective lens glass 11 and fix the position of the reflective lens glass 11.

[0036] like Figure 1 and Figure 2As shown, the reflective lens positioning device also includes a reset mechanism for controlling the movement of the positioning block 8. The reset mechanism includes a limit pin 13 and a reset spring 9 that is mounted on the limit pin 13 and is used to apply an elastic force to the positioning block 8. The positioning block 8 is mounted on the limit pin 13. The limit pin 13 is arranged horizontally and fixedly mounted on the fetal membrane 4. There are multiple limit pins 13, which guide the positioning block 8 and ensure stable operation of the positioning block 8. The reset spring 9 applies an elastic force to the positioning block 8, causing it to move toward a position away from the positioning groove. When the first electromagnet 6 and the second electromagnet 7 are not energized, the elastic force applied by the reset spring 9 keeps the positioning block 8 away from the positioning groove, without affecting the placement and removal of the ITO lens glass 12 and the reflective lens glass 11.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, two limit pins 13 are provided in the reflective lens positioning device, and a return spring 9 is provided on each limit pin 13. The return spring 9 is clamped between the positioning block 8 and the fetal membrane 4. The return spring 9 is a cylindrical coil spring and a compression spring.

[0038] like Figure 1 and Figure 2 As shown, the reflective lens positioning device also includes a guide pin 14 arranged on the fetal membrane 4, and a guide hole for the guide pin 14 to pass through is provided on the positioning block 8. The guide hole is a waist-shaped hole, and the length of the guide hole is greater than the diameter of the guide pin 14. The length direction of the guide hole is parallel to the moving direction of the positioning block 8. The guide pin 14 is vertically arranged, and the guide pin 14 plays a guiding role for the positioning block 8.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, three reflective lens positioning devices are provided.

[0040] The reflective lens positioning device of the above structure has a simple structure, occupies little space, is easy to arrange, has a high degree of automation, and helps to improve the efficiency of the automotive rearview mirror EC lens assembly fitting work.

[0041] like Figure 1 As shown, the sensing device includes an infrared transmitter 5 and an infrared receiver 10, which are arranged on the fetal membrane 4. When the infrared receiver 10 receives the infrared light emitted by the infrared transmitter 5, it sends a signal to the controller. After receiving the signal, the controller controls the first electromagnet 6 and the second electromagnet 7 to be energized.

[0042] The present invention also provides a method for laminating an automotive rearview mirror EC lens assembly, which uses an automotive rearview mirror EC lens assembly laminating tool and includes the following steps:

[0043] S1, placing the ITO lens glass 12 on the fetal membrane 4;

[0044] S2, the sensing device sends a trigger signal, and the reflective lens positioning device is in a working state capable of positioning the reflective lens glass 11;

[0045] S3, applying glue on the ITO lens glass 12;

[0046] S4, placing the reflective lens glass 11 on the ITO lens glass 12, and positioning the reflective lens glass 11 with a reflective lens positioning device. The circumference of the ITO lens glass 12 is 1.2 mm larger than that of the reflective lens glass 11;

[0047] S5. Apply UV glue from above;

[0048] S6, solidification;

[0049] S7. Take out the EC lens assembly.

[0050] In step S1, the ITO lens glass 12 is placed in the positioning groove of the fetal membrane 4, with the ITO lens glass 12 in a horizontal position to achieve positioning. When the ITO lens glass 12 is placed, the position of the operator's hand is determined by a sensing device. When the hand blocks the infrared light, the sensing device cannot send a trigger signal, the first electromagnet 6 and the second electromagnet 7 are de-energized, and the positioning block 8 is located away from the positioning groove, facilitating the placement of the ITO lens glass 12.

[0051] In the above step S2, after the infrared receiver 10 receives the infrared ray emitted by the infrared transmitter 5, it sends a signal to the controller. After receiving the signal, the controller controls the first electromagnet 6 and the second electromagnet 7 of all the reflective lens positioning devices to be energized. Under the action of the repulsive force of the same magnetic poles, the positioning block 8 extends from the guide groove, and the positioning block 8 moves toward the positioning groove. The reset spring 9 is compressed, and finally the positioning block 8 moves to the positioning position.

[0052] In the above step S3 , epoxy glue is coated on the ITO lens glass 12 .

[0053] In the above step S4, after applying the epoxy glue, the reflective lens glass 11 is placed on the ITO lens glass 12, and the ITO lens glass 12 and the reflective lens glass 11 are bonded together by the epoxy glue, and the reflective lens positioning device positions the reflective lens glass 11.

[0054] In the above step S5 , UV glue is applied from above the reflective lens glass 11 , and the ITO lens glass 12 and the reflective lens glass 11 are temporarily fixed by the UV glue.

[0055] In the above step S6, an ultraviolet lamp is used to cure the UV glue to achieve rapid curing.

[0056] In step S7, after the curing is completed, the EC lens assembly is formed. The EC lens assembly is then removed and placed in a heating box for heating. When removing the EC lens assembly, a sensing device determines the position of the operator's hand. If the hand blocks the infrared light, the sensing device cannot generate a trigger signal, the first electromagnet 6 and the second electromagnet 7 are de-energized, and the positioning block 8 is reset, away from the positioning slot, facilitating the removal of the EC lens assembly.

[0057] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
