Description

Linkage mechanism

The invention relates to a linkage mechanism, in particular to a linkage mechanism applied to an image measuring machine and moving a backlight module of the image measuring machine together with the lens.

The image measuring machine breaks the pattern of using the manual to measure the dimensions of the product and its shape and bit tolerance to judge whether the product is qualified or not. The image measuring machine uses the backlight module to project the product, and then uses the lens of the image measuring machine to judge the yield of the product shape. This is a traditional manual judgment, which undoubtedly greatly improves the work efficiency and reduces the human error. However, the backlight module of the conventional image measuring machine cannot move in synchronization with the lens. In order to meet the needs of the lens at various positions, the backlight module has to be arranged as a strip light source that runs through opposite ends of the table. When the lens of the image measuring machine is moved to another place, the light source that does not correspond to the lens cannot be turned off, resulting in a large amount of energy waste. At the same time, the operator looks at the light source that does not correspond to the lens for a long time, which damages the visual acuity and causes a certain human error.

In view of the above, it is necessary to provide a linkage mechanism that enables the backlight module of the image measuring machine to move together with the lens.

An interlocking mechanism is applied to an image measuring machine to move a backlight module of the image measuring machine together with a lens, the image measuring machine comprising a working table, a driving mechanism for driving the lens to move, and a mounting on the working table a bracket having first and second fixing plates, the fixing plate and the driving The mechanism is connected and movable with the driving mechanism, the linkage mechanism includes first and second pulleys mounted on the first end of the bracket, a third pulley mounted on the second end of the bracket, and a second fixed to the working platform a second fixing member, a sliding rail fixed between the first and second fixing members, a sliding member sliding along the sliding rail, and a rope for sliding the sliding member, the backlight module is fixed In the sliding member, the first fixing member is provided with first and second pulleys, and the second fixing member is provided with a third pulley. One end of the rope is fixed to the first fixing plate, and the other end sequentially bypasses the bracket. The first pulley, the first and third pulleys of the first and second fixing members, pass through and fix to the sliding member, and then sequentially bypass the second pulley of the first fixing member, the second of the bracket The third pulley is fixed to the second fixing plate, and when the driving mechanism drives the lens to move, the driving mechanism drives the fixing plate to move together with the rope, and the rope drives the sliding member to move together through the pulley, thereby driving the Backlight module Camera movements.

Turning on the power causes the backlight module 10 to emit light. When the tester operates the driving mechanism to move the lens to the right as needed, the driving mechanism pulls the first and second fixing plates 240, 242 and the rope 100 connected thereto to move to the right. Therefore, the rope 100 connected to the first fixing plate 240 bypasses the first pulley 502 of the fixing member 50 and the third pulley 530 of the fixing member 53, and has a pulling force to the right of the positioning block 90 and the connecting member 36, and drives the positioning block. 90 and connector 36 move to the right. The rope 100 connected to the second fixing plate 242 also moves to the right. At this time, the backlight module 10 fixed to the connecting member 36 is also moved along with the connecting body 36 to achieve the effect of synchronous movement with the lens. At this time, one end of the link 14 connected to the connecting member 36 moves to the right with the connecting member 36, and the portion of the bracket 14 at the top end of the guide rail 324 of the slide rail 32 is moved to the supporting portion 162 of the bracket 16. When the tester operates the drive mechanism to move the lens to the left as needed, the movement is similar to the movement of the lens to the right, but the direction is different.

In other embodiments of the interlocking mechanism of the present invention, the positioning block 90 may not be required, and a through hole for passing the rope 100 may be disposed directly on one side of the through groove 360 of the connecting member 36, and a top portion of the connecting member 36 is provided. The fixing holes intersecting the through holes pass through the fixing holes to lock the rope 100 to the connecting member 36.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations in the spirit of the present invention will be apparent to those skilled in the art.
