1 to 6 show a preferred embodiment of the edge cleaning apparatus 100 of the present invention, which includes a channel 101, an ultrasonic cleaning machine (not shown), a plate edge wiping mechanism 102, and a plasma cleaning. Machine (not shown). The channel 101 is for a substrate 2 to pass through, so that the edge of the substrate 2 can be ultrasonically cleaned, wiped and dried in sequence, and finally plasma-cleaned to complete the entire board edge cleaning operation. Wherein, the edge wiping mechanism 102 is controlled by a control system (for example, a PLC control system), so that the edge wiping mechanism 102 can drive a wiping strip 1 (for example, a non-woven strip) to advance the wiping cloth. The front surface of the strip 1 wipes the top surface of the edge of the substrate 2 (for example, a liquid crystal panel), and the wiping strip 1 is turned over to pass the bottom surface of the edge of the substrate 2 so that the back surface of the wiping strip 1 wipes the substrate 2 the bottom of the edge.

Referring to the first to third figures, the substrate 2 enters the edge wiping mechanism 102 from the channel inlet 101a on the right side of the drawing, and continues to be wiped by the edge wiping mechanism 102. After that, it is separated by the channel exit 101b on the left side of the figure. The movement stroke of the substrate 2 is mainly set in advance in conjunction with the operation of the edge wiping mechanism 102. More specifically, the edge wiping mechanism 102 is deliberately disposed in the process of flipping the wiping strip 1 so that the wiping strip 1 avoids the passage 101 without affecting the passage of the substrate 2 through the passage 101. As shown in the fifth figure.

Specifically, referring to the first figure, the edge wiping mechanism 102 includes a frame 3 and a feeding module 4 disposed on the frame 3, a first clamping wheel set 51 and a second clamping wheel set 52. A feed detection and buffer module 61, a receiving detection and buffer module 62, a strip turning mechanism 7 and a strip driving device 8.

The feeding module 4 includes a feeding wheel 41 and a feeding driving device 42 (for example, a motor), wherein the feeding wheel 41 is for loading the wiping strip 1 bundled into a roll, and the feeding driving device 42 is for driving The feeding wheel 41 sends the wiping strip 1 and sends it to the feeding detection and buffer module 61.

Generally, after the wiping strip 1 is sent out from the feeding wheel 41, the feeding detection and buffering module 61, the second clamping wheel set 52, the first clamping wheel set 51, and the cloth are sequentially passed. The strip reversing mechanism 7 and the receipt detecting and buffering module 62 finally pass through the strip driving device 8, and are pulled by the strip driving device 8 to leave the edge wiping mechanism 102. On the other hand, after the CCD image is aligned, the substrate 2 enters through the channel inlet 101a on the right side of the figure, and then sequentially passes through the cloth bar turning mechanism 7, the first pin wheel set 51 and the second pin wheel. Group 52 is finally separated by the channel exit 101b on the left side.

In detail, the first pinch wheel set 51 has an upper upper clamping wheel 511 and a lower clamping wheel 512. The upper clamping wheel 511 is driven by a steam pressure cylinder 513 above it to be vertically displaced between a home position (first figure) and a clamping position (second figure). The lower pinch wheel 512 is driven by a lower steam pressure cylinder 514 to be vertically displaced between a home position (first figure) and a pinch position (second figure). The rollers used by the upper and lower clamping wheels 511, 512 are all idlers, and the pneumatic cylinder 513 (514) can control the upper and lower clamping wheels 511, 512 (521, 522) by a pneumatic proportional valve. Clamp pressure channel.

Similarly, the second pinch wheel set 52 has an opposite upper pinch wheel 521. And the pinch wheel 522. The upper clamping wheel 521 is driven by a steam pressure cylinder 523 above it to be vertically displaced between a home position (first figure) and a clamping position (third figure). The lower pinch wheel 522 is driven by a lower steam pressure cylinder 524 to be vertically displaced between a home position (first figure) and a pinch position (third figure). The rollers used by the upper and lower pinch rollers 521, 522 are all idlers.

On the other hand, the substrate 2 is transported by a transfer device (not shown) to a wiping area between the first pinch set 51 and the second pinch set 52 to receive the wiper strip. 1 wipe. As shown in the second figure, the front edge of the substrate 2 is located at the nip position between the upper and lower pinch rollers 511, 512 of the first idle wheel set 51. At this time, a preceding segment of the wiping strip 1 passing through the upper and lower pinch rollers 511, 512 (not labeled, this refers to a small segment of the upper clamping wheel 511) and a posterior segment (Fig. Unreferenced, this means that a small segment of the lower clamping wheel 512 is pressed against the top and bottom surfaces of the edge of the substrate 2 by the pressing of the upper and lower clamping wheels 511, 512, respectively. In other words, the substrate 2 can be simultaneously wiped by the two segments of the wiping strip 1 during the advancement. Moreover, the preceding segment wipes the top surface of the edge of the substrate with its front side, and the rear segment wipes the bottom surface of the edge of the substrate with its back side due to the inversion of the strip turning mechanism 7. Therefore, both the front and back sides of the wiping strip 1 are used to wipe the substrate 2.

Referring to the second figure, the feed detection and buffer module 61 is located in the upper half of the frame 3 and includes a strip steering mechanism 611 and a strip adjusting mechanism 612. The strip steering mechanism 611 is composed of a plurality of idler pulleys or steering wheels (not shown) for guiding the wiping strip 1a to wrap around the feed wheel 41 with its "back side up" The lower side of the upper clamping wheels 511, 521 is advanced in a positive X-axis direction, that is, to the strip turning mechanism 7 on the side of the frame 3. Thus, after the two upper clamping wheels 511, 521 are lowered, the front surface of the wiping strip 1a can contact the top surface of the edge of the substrate 2. The strip adjusting mechanism 612 is inserted into the strip steering mechanism 611 so that the wiping strip 1a maintains an appropriate tension when pushed up and down by the upper gripping wheels 511, 521. More specifically, the strip adjusting mechanism 612 is configured to detect the length of the wiping strip 1a between the feeding wheel 4 and the two upper clamping wheels 511, 521. And when the wiping strip 1a is lengthened to reach a predetermined upper limit, the feeding module 4 stops the feeding of the wiping strip 1a, and when the wiping strip 1a becomes short to reach a predetermined lower limit The feeding module 4 is restored to convey the wiping strip 1a.

After the wiping strip 1b leaves the upper clamping wheels 511, 521, it goes to the strip turning mechanism 7 to perform the turning process. As shown in the third figure, the wiping strip 1b is turned over after being passed around the strip reversing mechanism 7, so that the wiping strip 1c after being turned over can still follow the substrate 2 in a "back facing up" posture. The lower portion advances in a negative X-axis direction as if it is rotated on the XZ plane (described later), and then proceeds to the receiving detection and buffer module 62.

Referring to the second figure, the receiving detection and buffer module 62 is located in the lower half of the frame 3 and includes a strip steering mechanism 621 and a strip adjusting mechanism 622. The strip steering mechanism 621 is composed of a plurality of idlers or steering wheels (not labeled) for guiding the wiping strip 1c around the upper sides of the lower jaws 512, 522 and toward the negative X-axis. Advancing, and then turning to the strip drive unit 8 below. Thus, after the two lower clamping wheels 512, 522 are raised, the back surface of the wiping strip 1c can contact the bottom surface of the edge of the substrate 2. The strip adjusting mechanism 622 is inserted into the strip steering mechanism 621 so that the wiping strip 1c maintains an appropriate tension when pushed up and down by the lower gripping wheels 512, 522. More specifically, the strip adjusting mechanism 622 is configured to detect a change in the length of the wiping strip 1d between the lower clamping wheels 512, 522 and the cloth driving device 8, and the length of the wiping strip 1d is long. When the preset upper limit is reached, the feeding module 4 stops the feeding of the wiping strip 1a, and when the wiping strip 1d becomes shorter to reach a predetermined lower limit, the feeding module 4 resumes the feeding of the wiping Cloth 1a. It can be seen that the feeding of the feeding module 4 is subject to the strip adjusting mechanism 612 of the feeding detection and buffer module 61 and the strip adjusting mechanism 622 of the receiving detection and buffer module 62.

In this embodiment, the mechanism and the operating principle of the strip adjusting mechanism 612 of the feeding detection and buffer module 61 and the strip adjusting mechanism 622 of the receiving detection and buffer module 62 are the same. One. Referring to the fourth figure and the second figure, the strip adjusting mechanism 612 of the feeding detection and buffer module 61 is taken as an example. In order to ensure that the wiping strip 1a is smoothly conveyed, the adjusting mechanism 612 includes a sliding rail 613, a sliding seat 614, an idler pulley 615, a lower detector 616 and an upper detector 617. As shown in the figure, the slider 614 is sleeved on the slide rail 613. The idler pulley 615 is pivotally disposed on the slide base 614 and is attached to the feed wheel 4 and the upper clamp wheel by its own weight. The lower detector 616 is used to detect whether the slider 614 has reached the bottom of the slide rail 613, and the upper detector 617 is used to detect the slider. Whether 614 has reached the top of the slide rail 613. In this embodiment, the lower detector 616 and the upper detector 617 both use a photo interrupter, so the slider 614 has a tab 618 for cutting the detection beam in the photointerrupter. For details, refer to Taiwan Patent Application Publication No. 201522181, entitled "Rolling and Transporting Mechanism". However, the foregoing configuration is only an example of the strip adjusting mechanism 612, and is not limited thereto. For example, an optical scale may be used instead.

In addition, the edge wiping mechanism 102 further includes a first clamping device 53 and a second clamping device 54. The first clamping device 53 is disposed on a moving path between the wiping strip 1b on the first clamping wheel set 51 and the strip turning mechanism 7; and the second clamping device 54 The wiping strip 1d is disposed on a moving path between the pinch wheel 522 and the strip driving device 8 below the second pinch wheel set 52. The first and second clamping devices 53 and 54 are used to clamp the wiping strip 1 before the clamping operation of the upper and lower clamping wheels 511 and 512.

Referring to the fifth figure, the strip turning mechanism 7 includes a first Y guide wheel 71, a first inclined guide wheel 72, three X guide wheels 73-75, and a second inclined guide wheel from top to bottom. 76 and a second Y guide wheel 77, whereby the back-facing wiping strip 1b is smoothly turned over, so that the inverted wiping strip 1c is rotated from below by the back-up posture. As the name suggests, the first and second Y guide wheels 71, 77 are oriented in the Y direction, and the X-axis wheels 73-75 are oriented in the X direction. More specifically, the first oblique guide wheel 72 has an angle of about 30 to 60 degrees between the axle direction and the X direction, and is perpendicular to the axle direction of the second inclined guide wheel 76.

In fact, the wiping strip 1b after wiping the substrate 2 can be rotated by 90 degrees after passing through the first Y-guide wheel 71 and the first X-guide wheel 73. The first inclined guide wheel 72 located between the first Y guide wheel 71 and the first X guide wheel 73 mainly assists the smooth rotation of the wiping strip 1b. Preferably, the angle between the axle direction of the first inclined guide wheel 72 and the X direction is 45 degrees. Similarly, the wiping strip 1b can be rotated 90 degrees after the third X-guide wheel 75 to the second Y-guide wheel 77, so that the third X-guide wheel 75 and the second Y-guide wheel 77 are located. The second inclined guide wheel 76 is mainly for assisting the smooth rotation of the wiping strip 1b. Preferably, the angle between the axle direction of the second inclined guide wheel 76 and the X direction is 45 degrees. In summary, the wiping strip 1b is rotated a total of 180 degrees from the first Y guide wheel 71 to the second Y guide wheel 77. It should be noted that the first X-guide wheel 73 of the X-guide wheels 73-75 is located directly below the first Y-guide wheel 72, and the third X-guide wheel 75 is located at the first X-guide wheel 73. Directly below, the second X-guide wheel 74 is misaligned with the first and third X-guide wheels 73, 75, whereby the X-guide wheels 73-75 jointly define a lateral space to avoid the substrate 2 The channel 101 that passes through.

Referring to the sixth and seventh figures, the strip driving device 8 mainly includes a motor 81, a transmission wheel 82 disposed on an output shaft (not shown) of the motor 81, and a quick release lever adjacent to the motor 81. 83. A linkage 84 connecting the quick release lever 83 and a pressure roller 85 disposed at one end of the linkage 84. Wherein, the connecting seat 84 is advanced or retracted by the interlocking lever 83, so that the pressing wheel 85 can be driven to press or release the wiping strip 1d passing between the pressing wheel 85 and the driving wheel 82. . Thus, the user can quickly clamp or loosen the wiping strip 1d by the pressing wheel 85 and the driving wheel 82 by switching the position of the quick release lever 83. When the wiping strip 1d is clamped, the motor 82 can continuously drive the wiping strip 1d to advance, so that the wiping strip 1d leaves the edge wiping mechanism 102, and vice versa. In addition, the strip driving device 8 further includes a sun gear 86 for calculating the advancement distance of the wiping strip 1d.

The operation of wiping the substrate by the edge wiping mechanism 102 when the substrate 2 passes through the channel 101 of the edge cleaning apparatus of the present invention will be described below: initially, as shown in the first figure, the edge wiping mechanism 102 is A clamping device 53 and a second clamping device 54 are in a loosened state, that is, the wiping strips 1b, 1d have not been clamped, and on the other hand, the substrate 2 has been aligned by the CCD image. Enter the channel 101.

Next, as shown in the second figure, the leading edge of the substrate 2 has reached between the upper and lower pinch rollers 511, 512 of the first pinch wheel set 51, and the first and second clamping devices 53, 54 are respectively clamped. The wiping strips 1b, 1d are held so that they cannot advance or retreat. After the wiping strips 1b, 1d are clamped, the upper and lower pinch rollers 511, 512 of the first pinch wheel set 51 are then relatively moved to a position where the substrate 2 is clamped. The clamping action of the first and second clamping devices 53, 54 prevents the wiping strips 1b, 1d from being pulled back during the subsequent clamping process, ensuring that the predetermined portions of the wiping strips 1b, 1d can be respectively separated. Adhered to the top and bottom surfaces of the edge of the substrate 2. It is to be noted that during the clamping of the upper and lower pincers 511, 512, the idler 615 of the strip adjusting mechanism 612 of the feeding detection and buffer module 61 is gradually released by releasing the wiping strip 1b. It rises slightly but has not yet reached the top of the strip adjustment mechanism 612. Similarly, the idler 625 of the strip adjusting mechanism 622 of the receiving detection and buffer module 62 is gradually released by the release of the wiping strip 1d during the clamping of the upper and lower clamping wheels 511 and 512. Rising, but also not reaching the top of the strip adjustment mechanism 622.

After being clamped by the upper and lower clamping wheels 511, 512 of the first pinch wheel set 51, the substrate 2 continues to advance along the channel 101, and during the advancement process, the upper and lower pinch wheels 511, 512 The wiping strips 1b, 1c are not moved, whereby the edges of the substrate 2 are cleaned by the saturated acetone or alcohol.

As shown in the third figure, when the leading edge of the substrate 2 advances between the second pinch wheel set 52 and the lower pinch wheel 521, 522, the upper and lower pinch wheels 521, 522 start to move relative to the pinch. The position of the substrate 2. At this time, the idler 615 of the strip adjusting mechanism 612 of the feeding detection and buffer module 61 is further raised, but has not yet reached the top of the strip adjusting mechanism 612, and the receiving detection and buffer module The idler 625 of the cloth regulating mechanism 622 of 62 is also the same. Subsequently, the substrate 2 continues to advance toward the channel outlet 101b after being sandwiched by the upper and lower pinch rollers 521, 522, and the edge of the substrate 2 is subjected to the upper and lower pincers 521 during the advancement process. The wiper strips 1a, 1d on 522 are wiped.

Until the end of the journey of the substrate 2, that is, the upper and lower clips are separated After the wheels 521, 522, the upper and second pinch wheels 511, 521 and the lower pinch wheels 512, 522 of the first and second pinch wheel sets 51, 52 are successively retracted, as shown in the first figure. The first and second clamping devices 53, 54 are then subsequently released, releasing the wiping strips 1b, 1d to allow the strip driving device 8 to subsequently pull the wiping strip 1d forward by a predetermined distance. (For example, 5 to 6 mm), the wiping strip 1 is advanced all the predetermined distance, and the sun gear 86 of the strip driving device 8 is used to calculate the predetermined distance. Thereby, the wiping portion of the wiping strip 1 can be renewed for wiping the next substrate.

As the wiping strip 1 is used step by step, the idler 615 of the strip adjusting mechanism 612 of the feed detecting and buffering module 61 will also gradually rise to the top of the strip adjusting mechanism 612. At this time, the feeding detection and buffer module 61 will immediately notify the feeding module 4 to feed, and the feeding process will continue until the idler 615 descends to the bottom of the strip adjusting mechanism 612. The feeding module 4 suspends feeding. Similarly, if the lower idler 625 is raised to the top of the strip adjusting mechanism 622, the receiving detection and buffer module 62 also notifies the feeding module 4 to feed until the idler 625 descends to the The feeding module 4 is required to suspend feeding until the bottom of the strip adjusting mechanism 622. It should be noted that when the feeding is to be performed, the pincers 511, 521, 512, and 522 must first be returned to the original position, and the clamping devices 53, 54 must also be in a released state.
