The adhesive tape application and removal device (sheet processing device) described in Patent Document 1 does not detect the deterioration of the non-adhesive treatment applied to the surface F (support surface) of the substrate support table 6 (support means), so excess adhesive tape Ta (unnecessary sheet) sticks to the support surface where the non-adhesive performance has been lost, resulting in a removal failure in which the unnecessary sheet is not removed from the support surface.

The object of the present invention is to provide a sheet processing apparatus and a sheet processing method that can prevent the occurrence of a peeling failure in which an unnecessary sheet is not peeled off from a support surface.

The present invention employs the configuration described in the claims.

According to the present invention, deterioration of the non-adhesive treatment applied to the support surface is detected, so that peeling failures in which the unnecessary sheet cannot be peeled off from the support surface can be prevented.

The articulated robot 31 is a so-called six-axis robot that can displace the cutting blade 32 to any position and angle within its working range.

In this embodiment, the detection means 50 is configured to detect the deterioration of the non-adhesive treatment of the sheet support surface 62B by detecting the vertical position of the supplied adhesive sheet base material AB. When the detection means 50 detects the deterioration of the non-adhesive treatment of the sheet support surface 62B, it outputs a detection signal, which is a predetermined signal such as electricity or radio waves, to each means, and also outputs the detection signal to warning devices (not shown) such as a display and a speaker.

The support means 60 includes a linear motor 61 as a driving device, and a table 62 supported by an output shaft 61A of the linear motor 61 and having an adherend support surface 62A capable of adsorbing and holding the adherend WK by a pressure reduction means (holding means) such as a pressure reduction pump or a vacuum ejector (not shown), and a sheet support surface 62B supporting the adhesive sheet substrate AB.
The sheet support surface 62B is subjected to a non-adhesive treatment such as a coating treatment such as a fluororesin coating or a silicone coating, or a roughening treatment such as a blasting process or an etching process.

The operation of the sheet processing apparatus EA will now be described.
First, a user of the sheet processing apparatus EA (hereinafter simply referred to as "user") sets the original web RS on the sheet processing apparatus EA, in which each member is arranged in the initial position shown by the solid line in Fig. 1(A), as shown in the figure, and then inputs a signal to start automatic operation via an operation means such as an operation panel or a personal computer (not shown). Next, when the user or a transport means (not shown) such as an articulated robot or a belt conveyor places the adherend WK at a predetermined position on the adherend support surface 62A as shown in Fig. 1(A), the support means 60 drives a pressure reducing means and a linear motor 61 (not shown) to start suction and holding the adherend WK on the adherend support surface 62A, and raises the table 62.

Then, the pressing means 20 drives the linear motor 21, and as shown by the two-dot chain line in Fig. 1(A), the pressing roller 22 is lowered to press the adhesive sheet substrate AB against the sheet support surface 62B with a predetermined pressing force. Next, the supplying means 10 drives the rotary motors 11L and 12E to wind up the release sheet RL and the adhesive sheet substrate AB, and when the load cell 11G detects that the tension of the adhesive sheet substrate AB located on the support means 60 has reached a predetermined value, the driving of the rotary motors 11L and 12E is stopped. Then, the supplying means 10 drives the linear motor 11F to sandwich the original roll RS between the pressing member 11D and the guide roller 11B, suppressing the supply of the adhesive sheet substrate AB. Next, the supply means 10 and the pressing means 20 drive the linear motors 11P, 11R, and 12A, and as shown in FIG. 1(B), the pressing roller 22 moves to the right while the frame 11S moves left and right and up and down so that the tension detected by the load cell 11G does not deviate from a predetermined value, and the pressing roller 22 presses the adhesive sheet base material AB against the sheet support surface 62B and the adherend WK to adhere them.

When the attachment of the adhesive sheet base material AB to the adherend WK is completed, the cutting means 30 drives the articulated robot 31, and as shown by the two-dot chain line in FIG. 1B, the cutting blade 32 pierces the adhesive sheet base material AB and moves the cutting blade 32 along the outer periphery of the adherend WK. As a result, a closed-loop cut is formed in the adhesive sheet base material AB, and the adhesive sheet AS is formed inside the cut and remains attached to the adherend WK, and the unnecessary sheet US is formed outside the cut. After that, the peeling means 40 drives the linear motor 12A and the rotary motor 12E, and as shown by the two-dot chain line in FIG. 1B and the solid line in FIG. 1C, the unnecessary sheet US is peeled off from the sheet support surface 62B while moving the frame 12C to the right, and the unnecessary sheet US is collected by the collection roller 12H. Here, if the non-adhesive treatment of the sheet support surface 62B deteriorates, as shown by the two-dot chain line in FIG. 1C, the unnecessary sheet US becomes difficult to peel off, and peeling is delayed compared to when the non-adhesive treatment is not deteriorated. Next, the support means 60 stops driving the decompression means (not shown) and releases the suction and holding of the adherend WK on the adherend support surface 62A. Then, when the user or the conveying means (not shown) conveys the adherend WK with the adhesive sheet AS attached to it to the next process, the supply means 10 and the pressing means 20 drive the linear motors 11F, 21, release the original roll RS from being pinched between the pressing member 11D and the guide roller 11B, and raise the pressing roller 22.

Next, with the supply means 10 stopping the drive of the rotary motor 12E, each means drives its respective drive device, and as shown in FIG. 1(A), each member is returned to its initial position and the adhesive sheet base material AB is supplied onto the sheet support surface 62B. Here, if the non-adhesive treatment of the sheet support surface 62B has not deteriorated, the vertical position of the adhesive sheet base material AB supplied onto the sheet support surface 62B falls within a predetermined position range. On the other hand, if the adhesive sheet base material AB that is continuous with the unnecessary sheet US whose peeling has been delayed due to deterioration of the non-adhesive treatment of the sheet support surface 62B is supplied onto the sheet support surface 62B, the adhesive sheet base material AB will be distorted or bent, and its vertical position will fall outside the predetermined position range.

Then, the detection means 50 drives the sheet position detection means 51 to detect the vertical position of the supplied adhesive sheet base material AB, and based on the detection result of the sheet position detection means 51, detects whether the non-adhesive treatment of the sheet support surface 62B has deteriorated. At this time, if the sheet position detection means 51 detects that the vertical position of the supplied adhesive sheet base material AB is located within a predetermined position range, the detection means 50 detects that the non-adhesive treatment of the sheet support surface 62B has not deteriorated, does not output a detection signal to each means or a warning device not shown, and the same operation as above is repeated thereafter. On the other hand, if the sheet position detection means 51 detects that the vertical position of the supplied adhesive sheet base material AB is out of the predetermined position range, the detection means 50 detects that the non-adhesive treatment of the sheet support surface 62B has deteriorated, and outputs a detection signal to each means and a warning device not shown. Next, when each means and warning device receives a detection signal, each means waits without performing the next operation, and the warning device emits a warning signal such as light or sound via a display or speaker to inform the user that the non-adhesive treatment of the sheet support surface 62B has deteriorated. Then, after the user replaces the table 62 or repairs the non-adhesive treatment, the user inputs the automatic operation start signal again via an operating means (not shown), and the same operations as above are repeated thereafter.

According to the above embodiment, deterioration of the non-adhesive treatment applied to the sheet support surface 62B is detected, so that a peeling failure in which the unnecessary sheet US is not peeled off from the sheet support surface 62B can be prevented.
