When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0046] See Figure 1-8 As shown, one embodiment of the present invention provides a secondary edge trimming mechanism suitable for photovoltaic modules, comprising:

[0047] The first guide rail 1 is symmetrically arranged on both sides of the conveyor belt 2. The length direction of the first guide rail 1 is consistent with the conveying direction of the conveyor belt 2. The photovoltaic module 3 is provided on the conveyor belt 2.

[0048] Width-direction adjusting slide rail assembly 4 is provided on the first guide rail 1, and the width-direction adjusting slide rail assembly 4 can slide along the first guide rail 1;

[0049] The edge trimming mechanism 5 is mounted on the width direction adjustment slide rail group 4. The edge trimming mechanism 5 can slide longitudinally along the width direction adjustment slide rail group 4, so that the edge trimming mechanisms 5 on both sides of the conveyor belt 2 approach each other to clamp the photovoltaic module 3, and can trim the edge of the photovoltaic module 3.

[0050] The aforementioned secondary edge trimming mechanism for photovoltaic modules utilizes first guide rails 1 arranged on both sides of the conveyor belt 2. The X-axis position of the edge trimming mechanism 5 is adjusted using the first guide rails 1, and the Y-axis position of the edge trimming mechanism 5 is adjusted using the width-direction adjusting slide rail group 4. This allows the edge trimming mechanisms 5 on both sides of the conveyor belt 2 to approach each other, clamping the photovoltaic module 3 and trimming its edges. It offers advantages such as high stability, low labor and hardware costs, high automation, and applicability to secondary edge trimming of different specifications and sizes of photovoltaic modules after layering.

[0051] In one embodiment of the present invention, the width-direction adjusting slide rail assembly 4 includes:

[0052] Adjust the base plate 41;

[0053] The second guide rail 42 is disposed on the upper surface of the adjusting base plate 41, and the edge trimming mechanism 5 is slidably disposed on the second guide rail 42;

[0054] The first slider 43 is symmetrically arranged on both sides of the bottom of the adjusting base plate 41, and the first slider 43 cooperates with the first guide rail 1;

[0055] The clamping unit 44 is fixed to the bottom of the adjusting base plate 41 and close to the end of the first slider 43. The clamping unit 44 is used to lock the first slider 43 onto the first guide rail 1.

[0056] In this embodiment, the first guide rail 1 is composed of two parallel first guide rail bodies. The two ends of the adjusting base plate 41 are respectively connected to the corresponding first guide rail bodies, and there are also two adjusting base plates 41. Thus, the adjusting base plates 41 and the first guide rail 1 can form a grid-like structure. The edge-trimming mechanism 5 slides along the second guide rail 42, which can adjust its Y-axis position, while the adjusting base plate 41 slides along the first guide rail 1, which can adjust the X-axis position of the edge-trimming mechanism 5, thereby enabling the edge-trimming mechanism 5 to cut photovoltaic modules 3 of different specifications and sizes.

[0057] In one embodiment of the present invention, the clamping unit 44 includes:

[0058] A fixing block 441 is fixed to the bottom of the adjusting base plate 41, and a groove 442 with an opening facing downward is provided on the fixing block 441;

[0059] The clamping block 443 is connected to both sides of the inner wall of the groove 442 by clamping screws 444, and the clamping block 443 is in contact with the two sides of the first guide rail 1.

[0060] In this embodiment, the first guide rail 1 is inserted into the groove 442. When the tightening screw 444 is rotated, the tightening blocks 443 on both sides of the inner wall of the groove 442 approach each other and press the first guide rail 1, thereby locking the first slider 43 onto the first guide rail 1 and fixing the position of the width-direction adjustable slide rail group 4.

[0061] Optionally, to further improve safety, a second limiting block 45 is provided at both ends of the second guide rail 42.

[0062] In one embodiment of the present invention, the edge-trimming mechanism 5 includes:

[0063] The Y-axis adjusting base plate 51 has a second slider 52 and a lower cylinder 53 fixed at the bottom. The second slider 52 cooperates with the second guide rail 42. The piston rod of the lower cylinder 53 is connected to the lower connecting plate 55 via a flange plate 54. The lower connecting plate 55 is provided with a cylinder transverse movement assembly 56.

[0064] The upper cylinder 57 is fixed on the upper surface of the Y-axis adjustment base plate 51. The upper cylinder 57 is connected to the upper connecting plate 59 via the connecting fixing plate 58. The upper connecting plate 59 is provided with an XY edge trimming module 510.

[0065] In this embodiment, the lower cylinder 53 can drive the Y-axis adjustment substrate 51 and the cylinder transverse movement group 56 to move closer or further away from each other, thereby adjusting the Y-axis position of the XY edge trimming module 510. The upper cylinder 57 can drive the XY edge trimming module 510 to extend or retract at an angle, so that the XY edge trimming module 510 can quickly clamp the adjacent edges of the photovoltaic module 3.

[0066] In one embodiment of the present invention, a buffer limiting group 511, a positioning blocking group 512, and a pneumatic control box group 513 are further fixed on the Y-axis adjustment substrate 51. In this embodiment, the buffer limiting group 511 may include a limiting block and a limiting switch, etc., for limiting the extreme positions of the Y-axis adjustment substrate 51 and the cylinder transverse movement group 56 as they approach or move away from each other. The positioning blocking group 512 may include a planar blocking block, which contacts the edge of the photovoltaic module 3 for positioning. The pneumatic control box group 513 is used to control the actions of the upper cylinder 57, the lower cylinder 53, etc.

[0067] In one embodiment of the present invention, a cable chain connecting plate 514 is fixedly mounted on the cylinder transverse movement assembly 56, and a cable chain 515 is provided on the cable chain connecting plate 514. The cable chain 515 is connected to the pneumatic control box assembly 513. This facilitates the cable arrangement of the pneumatic control box assembly 513 and improves the safety of use.

[0068] In one embodiment of the present invention, the XY trimming module 510 includes:

[0069] The edge-cutting fixing plate 5101 is connected to the upper connecting plate 59;

[0070] The third guide rail 5102 is fixed to the bottom of the edge-cutting fixing plate 5101. The third guide rail 5102 cooperates with the fourth slider 5107, which is fixedly connected to the Y-axis adjustment base plate 51.

[0071] A transverse cylinder 5103 and a longitudinal cylinder 5104 are fixed on the edge-trimming fixing plate 5101. Both the transverse cylinder 5103 and the longitudinal cylinder 5104 are provided with edge-trimming fixing plates 5105. The edge-trimming fixing plate 5105 is provided with a cutting blade assembly 5106. The cutting blade assemblies 5106 on the transverse cylinder 5103 and the longitudinal cylinder 5104 are distributed at right angles.

[0072] In this embodiment, when the upper cylinder 57 is activated, the third guide rail 5102 can slide along the fourth slider 5107, thereby causing the Y-axis adjusting substrate 51 and the XY edge trimming module 510 to extend or retract at an angle. When the transverse cylinder 5103 and the longitudinal cylinder 5104 are activated, the two cutting blade groups 5106, which are distributed at right angles, can perform transverse and longitudinal cutting operations on the edge of the photovoltaic module 3.

[0073] In one embodiment of the present invention, the cutting tool assembly 5016 includes:

[0074] Cutter cylinder 50161;

[0075] The cutting tool fixing component 50162 is connected to the cutting tool cylinder 50161, and the cutting tool fixing component 50162 is provided with a cutting tool 50163 and a pressure roller assembly 50164.

[0076] In this embodiment, the cutting depth of the cutter 50163 on the edge of the photovoltaic module 3 can be adjusted by the action of the cutting cylinder 50161 to ensure the cutting effect. The pressure roller assembly 50164 plays a guiding role, making the cutting process smoother.

[0077] In one embodiment of the present invention, the cylinder transverse movement assembly 56 includes:

[0078] A cylinder transverse movement fixing plate 561 is fixed on a fifth slider 562, and the fifth slider 562 is slidably engaged with a second guide rail 42.

[0079] The guide rail clamping assembly 563 is fixed on the cylinder transverse movement fixing plate 561;

[0080] The cylinder transverse movement limiting assembly 564 is fixed on the cylinder transverse movement fixing plate 561. The cylinder transverse movement limiting assembly 564 has a limiting groove 565 inside, and the limiting groove 565 cooperates with the buffer limiting assembly 511.

[0081] In this embodiment, the structure and principle of the guide rail clamping assembly 563 and the clamping unit 44 are basically the same, and will not be described again here. The limiting block and limiting switch of the buffer limiting assembly 511 can limit and detect the inner wall of the limiting groove 565.

[0082] The working principle of this invention is as follows:

[0083] After the photovoltaic module 3 is moved to a fixed position by the conveyor belt 2, the secondary edge trimming mechanism starts working. First, the lower cylinder 53 moves to the positioning stop group 512 to fix the photovoltaic module 3. Then, the upper cylinder 57 moves. Next, the cutting blade cylinder 50161 pushes out to the cutting blade 50163 and the pressure roller group 50164 close to the sides of the photovoltaic module 3. Then, the horizontal cylinder 5103 and the vertical cylinder 5104 pull back the guide rod to control the cutting blade 50163 to remove the residual glue around the sides of the photovoltaic module 3. Then, the lower cylinder 53 and the upper cylinder 57 pull back the guide rod, thus completing one edge trimming cycle. The whole process is repeated.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above merely illustrate several implementations of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
