[0042] The edge trimming device connects the driving source to the blade 100 through the transmission assembly, drives the transmission assembly by the driving source, and drives the blade 100 to move. The sensing assembly is connected to the transmission assembly, and the controller is connected to the driving source. The sensing assembly is used to record the actual edge trimming times of the blade 100 and transmit the actual edge trimming times to the controller. The controller compares the edge trimming times with the preset edge trimming times. If the actual edge trimming times are greater than the preset edge trimming times, it is judged that the area of the blade 100 used for cutting is seriously worn, the area of the blade 100 used for cutting is blunt, and it is not suitable for continuous cutting. At this time, the controller controls the driving source to drive the transmission assembly to move, and then drives the blade 100 to move, adjusts the area of the blade 100 used for cutting, and adjusts the area of the blade 100 used for cutting. The blunt area is not used. The edge trimming device provided in the application drives the blade 100 to move by the driving source. One blade 100 can be reasonably used for multiple times, the number of uses of the blade 100 is improved, the generation cost is reduced, the scrap rate of the photovoltaic module is reduced, the probability of safety accidents caused by replacing the blade 100 is reduced, the number of manual replacement of the blade 100 is reduced, and the work efficiency is improved.

[0043] In some embodiments, the driving source is a motor or a pneumatic cylinder. The output end of the motor or the output end of the pneumatic cylinder is connected to the transmission assembly, the transmission assembly is driven to move by the motor or the pneumatic cylinder, and then the blade 100 is driven to move.

[0044] Specifically, as shown in Figs. 1-3 The transmission assembly includes a transmission shaft 200, the blade 100 is provided with a limiting groove 121, the transmission shaft 200 extends into the limiting groove 121, the transmission shaft 200 is connected to the output end of the driving source, and the driving source drives the transmission shaft 200 to move to push the blade 100 to move. The transmission shaft 200 extends into the limiting groove 121 on the blade 100, the transmission shaft 200 is driven to move by the driving source, the transmission shaft 200 abuts against the groove wall of the limiting groove 121, thereby pushing the blade 100 to move, and replacing the area of the blade 100 used for cutting.

[0045] Specifically, as shown in Figs. 1-3 The transmission assembly further includes a positioning piece 300, the positioning piece 300 is in sliding fit with the blade 100, the transmission shaft 200 penetrates through the positioning piece 300 and extends into the limiting groove 121, and the transmission shaft 200 and the positioning piece 300 are threadedly connected. By providing the positioning piece 300, the positioning piece 300 and the blade 100 are in sliding fit, the movement direction of the blade 100 is defined by the sliding fit of the positioning piece 300 and the blade 100. The transmission shaft 200 penetrates through the positioning piece 300 and extends into the limiting groove 121 of the blade 100, the transmission shaft 200 and the positioning piece 300 are threadedly connected, the driving source drives the transmission shaft 200 to rotate, the transmission shaft 200 rotates while moving along the axial direction of the transmission shaft 200, and then pushes the blade 100 to move along the axial direction of the transmission shaft 200.

[0046] Specifically, the knife is like Figs. 1-3 As shown, one of the blade 100 and the positioning member 300 is provided with a groove 122, and the other is provided with a slider 400 that slides in cooperation with the groove 122. The extending direction of the groove 122 is parallel to the axial direction of the drive shaft 200. By providing the groove 122 on one of the blade 100 and the positioning member 300, and the slider 400 on the other, the sliding cooperation between the groove 122 and the slider 400 defines the direction of movement of the blade 100. Since the extending direction of the groove 122 is parallel to the axial direction of the drive shaft 200, the blade 100 is limited to move along the axial direction of the drive shaft 200, thereby changing the cutting area.

[0047] Specifically, such as Figs. 1-3 As shown, the blade 100 includes a cutting portion 110 and an abutment portion 120 connected to each other. The cutting portion 110 is used to cut photovoltaic modules, and the abutment portion 120 is provided with a limiting groove 121 and a sliding groove 122. When the drive shaft 200, which is used by the cutting portion 110 of the blade 100 to cut the photovoltaic modules, passes through the positioning member 300 to drive the blade 100 to move, the cutting area of ​​the cutting portion 110 of the blade 100 can be replaced, and one blade 100 can be used multiple times, increasing the number of uses of the blade 100. The limiting groove 121 is provided on the abutment portion 120 of the blade 100, and the end of the drive shaft 200 away from the drive source extends into the limiting groove 121 to limit the end of the drive shaft 200. Moreover, the sliding groove 122 is provided on the abutment portion 120 of the blade 100, and the slider 400 is provided on the positioning member 300, allowing the blade 100 to slide along the axial direction of the drive shaft 200.

[0048] More specifically, such as Figs. 1-3 As shown, the limiting groove 121 is a square groove. By setting the limiting groove 121 as a directional groove, when the drive shaft 200 extends into the limiting groove 121, the contact area between the limiting groove 121 and the end of the drive shaft 200 is increased, reducing the probability of the drive shaft 200 deviating when the drive shaft 200 pushes the blade 100 to move.

[0049] More specifically, such as Figs. 1-3 As shown, two slide grooves 122 are provided, distributed in a direction perpendicular to the axial direction. Two sliders 400 are also provided, each corresponding to one of the slide grooves 122. Two limiting grooves 121 are provided on the abutment portion 120 of the blade 100, and two sliders 400 are provided on the positioning member 300, each corresponding to one of the slide grooves 122. The sliders 400 can move within their respective slide grooves 122. The distribution of the two slide grooves 122 in a direction perpendicular to the axial direction further limits the movement direction of the blade 100.

[0050] More specifically, such as Figs. 1-3As shown, the limiting groove 121 is arranged between the two sliding grooves 122 and extends along the axial direction. The limiting groove 121 is arranged between the two sliding grooves 122, i.e., the sliding grooves 122 are arranged on both sides of the limiting groove 121, and the limiting groove 121 extends along the axial direction of the transmission shaft 200. When the transmission shaft 200 extends into the limiting groove 121 to push the blade 100 to move, the sliding groove 122 on the blade 100 and the sliding block 400 of the positioning member 300 are in sliding fit.

[0051] More specifically, the length direction of the blade 100 is parallel to the axial direction of the transmission shaft 200. The abutting portion 120 and the cutting portion 110 of the blade 100 are arranged along the axial direction.

[0052] In some embodiments, the edge trimming device further comprises an alarm member connected to the controller, and the controller is configured to control the alarm member to alarm when the blade 100 does not move by the preset distance. By arranging the alarm member, the controller can know the moving distance of the blade 100 according to the number of rotations of the transmission shaft 200. If it is detected that the driving source drives the transmission shaft 200 to rotate by the preset number of rotations, but the blade 100 does not move by the preset distance, the controller controls the alarm member to alarm at this time, prompting the staff to overhaul.

[0053] The technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.
