[0026] In view of the defects of the related art, this embodiment provides a glue removal device 100. Figure 1 As shown, the adhesive removal device 100 of this embodiment includes a loading end 101 and a unloading end 102 opposite to each other in a first direction a. Exemplarily, the first direction a is the length direction of the adhesive removal device 100 of this embodiment. The loading end 101 is provided with a first sensor 103, and the unloading end 102 is provided with a second sensor 104. Exemplarily, the first sensor 103 and the second sensor 104 are both photoelectric sensors, but are not limited thereto.

[0027] A first glue removal roller 110 and a second glue removal roller 120 are arranged between the loading end 101 and the unloading end 102. The first glue removal roller 110 is used to remove waste glue on the opposite side edges of the plate A in the first direction a. Exemplarily, the opposite side edges of the plate A in the first direction a are the two short sides of the plate A.

[0028] The second adhesive removal roller 120 is used to remove waste adhesive from the two opposite sides of plate A in the second direction b. By way of example, the second direction b is the width direction of the adhesive removal equipment 100 of this embodiment, and the two opposite sides of plate A in the second direction b are the two long sides of plate A.

[0029] Continue to combine Figure 2a to Figure 2bAs shown, during the process of the plate A passing through the loading end 101 and the unloading end 102 in sequence, as shown in FIG. Figure 2a As shown, the first sensor 103 first senses the plate A. When the control device of the degumming equipment 100 of this embodiment receives the signal state of the first sensor 103 as 1, the first degumming roller 110 and the second degumming roller 120 are started to prepare for degumming the plate A. Exemplarily, the scraping part of the first degumming roller 110 will cover the width of the entire plate A, so that as the plate A moves, the first degumming roller 110 can remove the waste glue on the short side of the plate A. The scraping parts of the first degumming roller 110 are arranged relatively in the second direction b, so that the second degumming roller 120 can remove the waste glue on the long side of the plate A during the entire movement of the plate A. Of course, the scraping part of the second degumming roller 120 can also cover the width of the entire plate A, so that in addition to scraping the waste glue on the long side of the plate A, the short side of the plate A is degummed for the second time.

[0030] like Figure 2a As shown, when the plate A just enters the debonding device 100 of this embodiment, the first debonding roller 110 is pressed against the head of the plate A (the plate A is at Figure 2a to Figure 2c Remove the glue from the short edge (on the right side).

[0031] Continue to refer to Figure 2b As shown, with the degumming action of the first degumming roller 110 and the second degumming roller 120, the plate A moves toward the unloading end 102 of the degumming equipment 100. When the head of the plate A reaches the second sensor 104, the second sensor 104 senses the plate A. When the control device of the degumming equipment 100 receives the signal state 1 of the second sensor 104, it turns off the first degumming roller 110, thereby preventing the first degumming roller 110 from idling.

[0032] Continue to refer to Figure 2c As shown, plate A moves further, when the tail of plate A (plate A is at Figure 2a to Figure 2c When the plate A passes through the first sensor 103, the first sensor 103 cannot continue to sense the plate A, so the signal state of the first sensor 103 changes to 0. After receiving the signal state change of the first sensor 103, the control device of the degumming equipment 100 starts the first degumming roller 110 again. As the plate A moves, the short side of the tail of the plate A is degummed by the first degumming roller 110.

[0033] When plate A moves further and passes the second sensor 104, it will leave the degumming equipment 100 of this embodiment, so that the second sensor 104 can no longer sense plate A, so the signal state of the second sensor 104 becomes 0. After the control device of the degumming equipment 100 receives the signal state change of the second sensor 104, in order to prevent the first degumming roller 110 and the second degumming roller 120 from idling, the first degumming roller 110 and the second degumming roller 120 are turned off.

[0034] Compared with the related art, when the degumming equipment 100 of this embodiment is used to remove the glue from the photovoltaic panel, the degumming roller starts to start when the photovoltaic panel enters the degumming equipment 100 of this embodiment, and the degumming roller will automatically turn off when the photovoltaic panel leaves the degumming equipment 100 of this embodiment, thereby reducing the idling of the degumming roller and improving the energy utilization efficiency of the degumming equipment 100.

[0035] Further, in the present embodiment, the first de-glue roller 110 is closer to the feeding end 101 than the second de-glue roller 120. Among them, a first transmission roller 130 is arranged between the first de-glue roller 110 and the feeding end 101, and a second transmission roller 140 is arranged between the second de-glue roller 120 and the unloading end 102. The de-glue device 100 also includes a first pressing roller opposite to the first transmission roller 130 in the third direction c (the height direction of the de-glue device 100 in the present embodiment), and a second pressing roller opposite to the second transmission roller 140 in the third direction c. The first transmission roller 130 and the second transmission roller 140 can convey the plate A at a uniform speed, and the first pressing roller and the second pressing roller apply pressure to the plate A, so that the plate A can be stably transmitted during the de-glue process. According to actual needs, the de-glue device 100 in the present embodiment may also include a third transmission roller opposite to the first de-glue roller 110 in the third direction c, and a fourth transmission roller opposite to the second de-glue roller 120 in the third direction c.

[0036] Furthermore, a dust collecting cover 150 is disposed below the first adhesive removal roller 110 and the second adhesive removal roller 120 to collect the scraped waste adhesive and facilitate subsequent cleaning work.

[0037] Continue to refer to Figure 1 As shown, in order to improve the debonding efficiency of the plate A, a transmission line 200 formed along the first direction a is further provided upstream of the feeding end 101 in this embodiment, and the transmission line 200 is used to transmit the plate A to be debonded. Centering mechanisms 210 are respectively provided on opposite sides of the transmission line 200 in the second direction b, and the centering mechanisms 210 are used to limit the plate A so that the plate A is kept aligned with the transmission line 200 during the transmission process.

[0038] Of course, according to actual needs, the debonded plate A can also be aligned when it is transferred to the next workstation, so a transmission line 200 and an alignment mechanism 210 on the transmission line 200 can also be set downstream of the unloading end 102.

[0039] Exemplarily, the centering mechanism 210 may include a plurality of push cylinders arranged opposite to each other in the second direction b. The plurality of push cylinders in the same row are used to push the movable sheet metal base together, and a plurality of limit stops are arranged on one side of the movable sheet metal base facing another movable sheet metal base.

[0040] Further, the receiving end of the transmission line 200 is provided with a third sensor, and the discharging end of the transmission line 200 is provided with a fourth sensor. When the plate A passes through the receiving end and the discharging end in sequence, when the third sensor senses the plate A, the centering mechanism 210 is started. Specifically, when the control device of the degumming equipment 100 of this embodiment receives the signal state of the third sensor as 1, it drives multiple push cylinders to push the movable sheet metal base on both sides to close the limit block, thereby limiting the plate A, so that the plate A and the transmission line 200 are kept in the center. Optionally, the limit block is made of silicone or rubber material, so as to ensure that the plate A is not damaged by excessive force while being subjected to uniform pressure. As the plate A moves, the fourth sensor will sense the plate A, which means that the plate A is about to leave the transmission line 200, so that the centering mechanism 210 needs to be closed. Specifically, when the control device of the degumming equipment 100 of this embodiment receives the signal state of the fourth sensor as 1, it resets the multiple push cylinders, so as not to limit the plate A.

[0041] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
