Sensing method and device for real end edge of hard plate member with soft edge

The invention relates to the technical field of sensing a hard plate member, in particular to a sensing technology for a hard plate member having a soft edge, and in particular to a method for automatically sensing a true edge of a hard plate member using a cutter and a method thereof Device.

The invention relates to a hard plate member with a soft bead edge, which is a plate member which is surrounded by a plurality of real end edges, and the plate member is coated or composited with a soft material, and the soft material is extended to the real part. A soft bead is formed on the periphery of the end. The hard material means that the hardness of the plate member is significantly harder than that of the soft material or the soft edge, but it does not mean that the hardness of the plate member is similar to that of a rigid body.

The above-mentioned hard plate member with soft bead edge can be seen in the solar panel of the packaging process at the current stage, and at least two layers of ethylene vinyl acetate copolymer (EVA) are respectively used as protective soft materials. And a layer of protective backsheet. In the recombination, in order to ensure that the above soft materials can be fully adhered to the double end faces of the entire solar panel, the bonding area of the soft materials generally exceeds the area of the double-end surface of the solar panel, resulting in the solar panel. At least one real end edge may be covered to form a soft crotch edge, and the at least one end edge means that the soft crotch edge is distributed around the periphery of the plurality of end edges of one or four sides of the solar panel.

In the packaging process described above, in order to smoothly carry out the processing operation, the solar panel is usually placed on a conveying device (or a conveyor belt) to carry the solar panel into each processing station. It is also known that before the solar panel is transported by the transport device into each processing zone station, the reference position of the solar panel must be predicted in advance to achieve the purpose of the automated packaging process of the solar panel.

However, due to the above-mentioned solar panel (or hard plate member) which has been compounded with soft materials, the outer edge of the real edge has been covered by a soft edge, which is soft, flexible and different in size. In the phase technology, the sensing elements such as light sensors or micro switches commonly used in conveying equipment are difficult to directly penetrate or contact, and to sense the true position of the real end edge that has been covered by the soft edge. As a result, the solar panel that has been composited with soft materials cannot be automatically perceived on the conveying device, and the automatic packaging operation of the solar panel is difficult.

SUMMARY OF THE INVENTION The object of the present invention is to solve the problem of a solar panel having a soft edge, which is difficult to automatically sense its reference position on the conveying device, and to provide a sensing method for the true end of the hard plate member having a soft edge.

However, in order to clearly and fully disclose the present invention, the preferred embodiments are illustrated, and the detailed description of the embodiments will be described as follows:

In view of the sensing method for realizing the true end edge of a hard plate member having a soft hem, please refer to FIG. 1 to FIG. 4 together. FIG. 1 is a plan view showing the object used in the method of the present invention, and FIG. 2 is a view. 1 is a top plan view of another embodiment of the object shown in FIG. 3, FIG. 3 includes FIG. 3a to FIG. 3c respectively illustrating an action diagram of the object shown in FIG. 1, and FIG. 4 is a block diagram of the method of the present invention.

As shown in FIGS. 1 and 3a, in order to implement the present invention, it is necessary to provide a cutter 1 and a rigid plate member 2. The cutting blade 1 is a contact element for sensing, and has a cutting edge 10 at one end thereof; the hard plate member 2 is a flat plate member surrounded by a plurality of real end edges 20 around the same, and the double end of the hard plate member The surface is respectively covered with a soft material 21a, 21b, and the soft material 21a, 21b extends to the periphery of at least one real end edge 20 to form a soft bead edge 21, so that the real end edge 20 is covered and placed in the soft crucible. Inside the side 21.

The blade 10 of the cutter 1 must have a hardness greater than the soft edge 21, so that the blade 10 can be used to cut the soft edge 21; the blade 10 has a hardness of preferably less than the rigid plate 2, so that the blade 10 does not damage the true end edge 20 of the rigid panel 2 when the soft edge 21 is cut.

The cutter 1 can be made of a metal alloy, a non-ferrous alloy or a non-metal. The hard plate member 2 may be a solar panel, and the solar panel is generally made of glass, but it is not excluded that the hard plate member 2 is made of a material other than glass.

When the hard plate member 2 is a solar panel, the double-end surface thereof is at least combined with a protective layer of Ethylene Vinyl Acetate (EVA) as a protective soft material 21a, and a layer as a back sheet ( The protective soft material 21b for Back Sheet). In the case of recombination, in order to ensure that the soft materials 21a and 21b can be sufficiently adhered to the double-end surfaces of the entire hard plate member 2, the bonding area of the soft materials 21a and 21b is generally higher than that of the hard plate member 2. The area of the double-ended surface causes at least one true end 20 of the hard plate member 2 to be wrapped to form a peripheral soft cuff 21, the at least one real end 20 being said to be distributed At the periphery of a plurality of real end edges 20 of one or the periphery of the hard plate member 2.

Based on the above, the sensing method of the present invention includes the following steps S1 to S3 (as shown in FIG. 4):

Step S1: Driving the cutter 1 to shift an arc path L (as shown in Fig. 3a). The arc path L is formed by at least one partial trajectory of circular motion. In practice, the cutter 1 can be driven by a driver (described in detail later) to displace the arc path L. When the cutter 1 is displaced, the blade 10 can maintain the linear erect posture to displace the arc path L, or the blade 10 can be displaced in the oscillating manner on the arc path L. Furthermore, in a further implementation, the arc path L may be a path of a straight line vector E, and the line vector E is perpendicular to the real end edge 20 (shown in FIG. 1), or the line vector E and the real end are The edges 20 form an oblique angle θ (shown in Figure 2) to facilitate the use of the blade 10 to slash the soft rim 21 . The above-described use of the cutter 1 displacement arc path L is intended to make the blade edge 10 of the cutter 1 more easily cut through the soft crotch edge 20.

Step S2: The cutting edge 10 of the cutting blade 1 is inserted into the soft rim 21 on the periphery of the real end edge 20 of the hard plate member 2 during the displacement of the arc path L (as shown in Fig. 3b). More specifically, the distance between the cutting blade 1 and the real end edge 20 must be within the displacement range of the arc path L; this can be transmitted to the adjacent cutting piece via a conveying device or manually. The position of the knife 1 is controlled; and the arc path L is utilized as a sensing range in which the cutter 1 can be blocked and stopped to provide a device-sensing margin R for performing the method. Moreover, the blade 10 must first break the soft edge 21 during the displacement of the arc path L to facilitate implantation into the real end edge 20; the linear vector E and the real end edge 20 are mutually The relationship of vertical or mutually oblique angle θ will help the blade 10 to easily break the soft edge 21 in the process of the displacement of the soft edge 21 during the displacement of the curved path L, thereby implanting the real Inside the end edge 20.

Step S3: Continuing to stop the cutting edge 10 implanted in the real end edge 20 touching the real end edge 20 (shown in FIG. 3c) to sense a true position P of the real end edge 20. More specifically, the cutter can be used to apply the cutter 1 to a specific force F (shown in FIGS. 1 and 2) to perform the arc path L displacement; the specific force F can be attached to the blade 10 to be cut and The soft rim 21 is implanted, but is resisted by the real end edge 20, so that the blade 10 stops displacement as soon as it contacts the real end edge 20. Furthermore, the present invention can use a sensing element (described in detail later) to stop the moment of displacement when the blade 10 contacts the real end edge 20, that is, to read a stop position of the cutting blade 1 during the displacement of the arc path. P1 (shown in FIG. 3c) records the stop position P1 via a control unit such as a programmable controller (PLC) or a computer (PC), and determines the true position P of the real end edge 20 at the stop position P1.

The above-described implementation steps can be embodied in a conveying device for placing or transferring the hard plate member 2, in particular a sensing device is arranged on the conveying device, according to which the above steps are carried out.

The position of the cylinder rod or piston in the cylinder. In this way, when the driver 3 drives the swing arm to generate the displacement of the arc path L, the sensing component 4 can read the position of the cylinder rod or the piston of the pneumatic cylinder driver, and then read the cutter 1 in the The stop position P1 during the displacement of the arc path L determines the true position P of the real end edge 20.
