Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a substrate conveying and positioning device for an online inspection machine. Background Art

[0002] Currently, most online inspection machines in the industry use fixed-position hardware blocking to detect the positioning of substrates during transport. This involves installing fiber optic sensors on a track, and using fiber optics, blocking cylinders, or blocking conveyor plates to continue transporting the substrate and thus locate its position. However, since the fiber optic sensors are fixed to the track, when the substrate type is changed or there are gaps, the sensors need to be rearranged and reinstalled, wasting manpower and reducing work efficiency. Therefore, this method needs to be improved. Utility Model Content

[0006] Furthermore, the first bracket includes a first connecting plate and a second connecting plate; the first connecting plate has an L-shaped structure, and the horizontal end of the L-shaped first connecting plate is connected to the top of the first extension plate, and the vertical end of the L-shaped first connecting plate extends downward; the second connecting plate has an L-shaped structure, and the horizontal end of the L-shaped second connecting plate is connected to one side of the vertical end of the L-shaped first connecting plate, and the vertical end of the L-shaped second connecting plate extends downward; wherein one of the position sensors is installed on one side of the vertical end of the L-shaped first connecting plate, and the other position sensor is installed on one side of the vertical end of the L-shaped second connecting plate.

[0007] Furthermore, the first through hole extends to one side of the first extension plate, and the first through hole has a semi-circular structure; the bottom of the first extension plate is also connected to a light source mounting plate with an annular structure, and the annular light source is mounted on the bottom of the light source mounting plate.

[0008] Furthermore, a first fixing plate is connected to the upper and lower parts of one side of the Z-axis lifting plate, and one end of each first fixing plate can be detachably connected to a first locking plate; a first arc-shaped groove with a semi-circular structure is opened on the opposite side of the first fixing plate and the corresponding first locking plate, and the two first arc-shaped grooves form a first fixing hole; the camera assembly includes a first camera, and the upper and lower parts of the first camera are each installed in a first fixing hole.

[0027] Continue to refer to Figures 1 to 7 As shown, in this embodiment, it also includes two Y-axis supports, which are arranged in parallel and spaced apart. The Y-axis translation mechanism 1 includes a Y-axis motor mounted on the top of one Y-axis support, a Y-axis lead screw assembly connected to the Y-axis motor, and a Y-axis slide rail assembly arranged on the top of the other Y-axis support. The Y-axis translation seat 2 has a U-shaped structure, and the two vertical ends of the U-shape of the Y-axis translation seat 2 are respectively connected to the Y-axis lead screw assembly and the Y-axis slide rail assembly. Driven by the Y-axis motor, the Y-axis translation seat 2 can be moved along the Y-axis slide rail assembly via the Y-axis lead screw assembly. The X-axis translation mechanism 3 includes an X-axis motor mounted on the top of the horizontal end of the U-shape of the Y-axis translation seat 2, an X-axis slide rail assembly, and... An X-axis lead screw assembly is connected to an X-axis motor; an X-axis translation seat 4 is slidably arranged on an X-axis slide rail assembly and connected to the X-axis lead screw assembly. Driven by the X-axis motor, the X-axis translation seat 4 can move along the X-axis slide rail assembly via the X-axis lead screw assembly; simultaneously, a Z-axis lifting mechanism 6 includes a Z-axis slide rail assembly, a Z-axis lead screw assembly, and a Z-axis motor connected to the Z-axis lead screw assembly, arranged on one side of the Z-axis mounting plate 5; a Z-axis lifting plate 7 is arranged on the Z-axis slide rail assembly and connected to the Z-axis lead screw assembly. Driven by the Z-axis motor, the Z-axis lifting plate 7 can move up and down along the Z-axis slide rail assembly via the Z-axis lead screw assembly, so that the camera assembly 8 can inspect the substrate.

[0028] Meanwhile, the first bracket includes a first connecting plate 75 and a second connecting plate 76; the first connecting plate 75 has an L-shaped structure, and the horizontal end of the L-shaped first connecting plate 75 is connected to the top of the first extension plate 71, and the vertical end of the L-shaped first connecting plate 75 extends downward; the second connecting plate 76 has an L-shaped structure, and the horizontal end of the L-shaped second connecting plate 76 is connected to one side of the vertical end of the L-shaped first connecting plate 75, and the vertical end of the L-shaped second connecting plate 76 extends downward; one of the position sensors 74 is installed on one side of the vertical end of the L-shaped first connecting plate 75, and the other position sensor 74 is installed on one side of the vertical end of the L-shaped second connecting plate 76.

The board is conveyed at a low speed to approach the first positioning sensor. When the first positioning sensor detects the board, the track stops conveying.

[0030] like Figure 5 As shown, when the board is fed on the right, during the conveying process, after the second deceleration sensor senses the substrate, the track conveying speed is reduced, and the board is conveyed at a low speed to approach the second positioning sensor. When the second positioning sensor senses the substrate, the track stops conveying.

[0031] like Figure 6 As shown, when there is a notch in the substrate, the camera is set to a stop position in the Y direction, thereby changing the sensor position so that the first deceleration sensor and the first positioning sensor of the substrate avoid the notch in the substrate.

[0032] like Figure 7 As shown, when conveying different substrate sizes, in order to keep the substrate always in the center of the machine, the background calculates the stop position of the substrate in the X direction according to the substrate X size, and automatically changes the stop position of the camera in the X direction, thereby changing the position of the positioning sensor.

The first through hole 72 is a light-transmitting hole, which facilitates the camera assembly 8 to inspect the product.

[0034] Meanwhile, a first fixing plate 84 is connected to the upper and lower parts of one side of the Z-axis lifting plate 7, and one end of each first fixing plate 84 is detachably connected to a first locking plate 85; a first arc-shaped groove with a semi-circular structure is opened on the opposite side of the first fixing plate 84 and the corresponding first locking plate 85, and the two first arc-shaped grooves form a first fixing hole; the camera assembly 8 includes a first camera 81, and the upper and lower parts of the first camera 81 are each installed in a first fixing hole. One end of the first locking plate 85 has a locking hole that extends through to the first fixing plate 84. After the first camera 81 is installed, a screw is locked into the locking hole to lock it in place, which is simple and convenient. In addition, a second fixing plate 82 is connected to each end of one side of the Z-axis lifting plate 7, and the lower part of the second fixing plate 82 is inclined downward toward the direction of the first through hole 72; the camera assembly 8 also includes a second camera 83, and the second camera 83 is installed on one side of the second fixing plate 82.

At the same time, a first limiting plate 54 is connected to the bottom of the Z-axis mounting plate 5, and a first buffer block 55 is mounted on the upper part of one side of the Z-axis mounting plate 5. The lifting stroke of the Z-axis lifting plate 7 can be limited by the first limiting plate 54 and the first buffer block 55, thereby improving its operational safety.
