It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] In the description of the present invention, it should be noted that the "left" and "right" directions refer to the width direction of the photovoltaic module, and the length direction of the clamp is consistent with the length direction of the photovoltaic module. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0032] Please also read Figures 1 to 6 , the dismantling device of the photovoltaic module junction box provided by the utility model is now described. The dismantling device of the photovoltaic module junction box comprises: a support frame 1, a bidirectional driving mechanism, two clamps 3 and a busbar cutting mechanism, the bidirectional driving mechanism is arranged on the support frame 1; the two clamps 3 are connected to the bidirectional driving mechanism, and are driven by the bidirectional driving mechanism to move closer to or away from each other to peel off the junction box 8; the clamp 3 is a wedge-shaped hollow structure, and the small end of the clamp 3 is provided with a slit 305 extending along its length direction; the busbar cutting mechanism is arranged in the hollow cavity of the clamp 3; the busbar 4 cutting mechanism comprises a linear actuator 6 and a cutter 5 connected to the end of the actuator rod of the linear actuator 6; the linear actuator 6 pushes the cutter 5 to extend or retract from the slit 305 to cut off the busbar 4 connected to the junction box 8.

[0033] Compared with the prior art, the photovoltaic module junction box removal device provided by the utility model has the following beneficial effects: when the waste photovoltaic module 2 is removed for recycling, the junction box 8 must be removed first, and when the junction box 8 is removed, the busbar 4 connected between the photovoltaic module 2 and the junction box 8 must be cut off first to completely separate the junction box 8 from the photovoltaic module 2 and remove the junction box 8; the removal device provided by the present application is divided into three steps, the first step is the pre-stripping of the junction box 8, firstly, the two clamps 3 are driven from the left and right directions to the junction box 8 by a bidirectional driving mechanism, the wedge-shaped small end of the clamp 3 is first inserted into the bottom of the junction box 8, and the clamp 3 continues to approach each other under the drive of the bidirectional driving mechanism, and the left and right sides of the junction box 8 are initially separated. The first step is to peel off the junction box 8 from the photovoltaic module 2. At this time, the junction box 8 is slightly lifted up due to the extension of the clamp 3. When the two clamps 3 contact the bus strip 4, the two-way driving mechanism stops moving, and the two clamps 3 clamp the bus strip 4 from the left and right sides; the second step is to start the linear actuator 6, driving the cutter 5 to extend from the slit 305 of the clamp 3 to cut the bus strip 4. The cutter 5 continues to move left or right under the drive of the linear actuator 6 until it moves to the clamp 3 on the other side, and the bus strip 4 can be completely cut off; the third step is to move the linear actuator 6 in the opposite direction, driving the cutter 5 to retract into the clamp 3, and the two-way driving mechanism is started, driving the clamps 3 to continue to approach each other, so that the junction box 8 can be completely peeled off from the photovoltaic module 2.

[0034] By utilizing the photovoltaic module junction box removal device provided in the embodiment of the utility model, the automatic cutting of the busbar 4 and the peeling and removal of the junction box 8 are realized at the same time, which saves time and effort; at the same time, it is configured on the automatic removal and recycling line of the photovoltaic module 2. When the photovoltaic module 2 is conveyed to the junction box 8 removal station through the conveying mechanism, the junction box 8 can be automatically peeled off from the photovoltaic module 2, and the remaining photovoltaic module 2 can reach the next process under the conveyance of the conveying mechanism, and other components of the photovoltaic module 2 can be removed and recycled, which can improve the degree of automation of the recycling of waste photovoltaic modules 2 and also improve the recycling efficiency of waste photovoltaic modules 2.

[0035] The fixture 3 provided in this embodiment is a hollow structure, which is convenient for arranging the cutter 5 and its driving mechanism and also reduces the overall weight; the fixture 3 without the cutter 5 is provided with an escape space when the cutter 5 runs to the fixture 3, so that the busbar 4 will not touch the fixture 3 when being cut.

[0036] In some embodiments, see Figure 2 As shown, the cutter 5 is connected to the actuator rod of the linear actuator 6 through a connecting rod, and a micro motor 11 is also provided on the connecting rod to drive the cutter 5 to rotate and cut. The linear actuator 6 is an electric push rod, a screw nut telescopic mechanism, a cylinder or a hydraulic cylinder, which has the performance of linear pushing or telescopic, thereby driving the cutter 5 to perform linear reciprocating motion, extending out of the clamp 3 to cut the busbar 4 or recovering it into the hollow cavity of the clamp 3. Figure 1 The arrow below the middle junction box 8 is the cutting direction of the cutter 5; the opposite arrow above the junction box 8 is the direction of the clamp 3 moving toward each other.

[0037] In some embodiments, the cutter 5 is a sawtooth disc, which cuts the bus ribbon 4 by rotating.

[0038] In some embodiments, the thickness of the cutter 5 is 1-1.8 mm. The busbar 4 is made of copper, and has a low thickness and hardness, and is easy to cut. The thickness and size of the selected slices are not large, so a suitable micro motor 11 can be selected and purchased.

[0039] In some embodiments, Figure 1 As shown, the bidirectional driving mechanism includes a bidirectional screw rod 9 and a left-handed nut 10 and a right-handed nut 7 which are screwed in opposite directions on the bidirectional screw rod 9; the two clamps 3 are respectively connected to the left-handed nut 10 and the right-handed nut 7. The rotation of the bidirectional screw rod 9 can drive the left-handed nut 10 and the right-handed nut 7 to move in opposite directions or towards each other, thereby driving the two clamps 3 to move closer to or farther away from each other.

[0040] The bidirectional driving mechanism may also be a slide rail with bidirectional movable sliders, and the clamp 3 may be connected to two bidirectional movable sliders.

[0041] In some embodiments, the support frame 1 includes two sets of lifting and adjusting mechanisms, and the two ends of the bidirectional screw 9 are driven to lift and lower through the lifting and adjusting mechanisms. The two sets of lifting and adjusting mechanisms are respectively arranged on the left and right sides of the photovoltaic module 2, and the two clamps 3 can be lifted and lowered at the same time by lifting and lowering the bidirectional screw 9. For example, when the two clamps 3 extend into the bottom of the junction box 8, the busbar 4 is cut off and the junction box 8 is peeled off from the photovoltaic module 2, the lifting and adjusting mechanism rises, and the two clamps 3 can hold the junction box 8 away from the photovoltaic module 2. If used on a production line, it is convenient for the photovoltaic module 2 to be transported backward with the conveying mechanism.

[0042] In some embodiments, the lifting and adjusting mechanism includes two adjusting screws and lifting nuts matched on the adjusting screws, and the two ends of the bidirectional screw 9 are connected to the lifting nuts through supports. The lifting and adjusting mechanism is to achieve linear motion, so it can also be replaced by an electric push rod or a linear slide. It is a common technical means to use the lifting and adjusting mechanism and other linear actuators 6 to lift the bidirectional screw 9, so it is not shown in detail in the figure.

[0043] In some embodiments, see Figures 3 to 5As shown, the fixture 3 includes a bottom plate 304, a wedge-shaped inclined plate 301, two end plates 303 and a side plate 302; wherein the two end plates 303 are trapezoidal structures, respectively connected vertically to the two ends of the length of the bottom plate 304; the inclined plate 301 is connected to the top of the two end plates 303, and a hollow cavity and the slit 305 are formed between the inclined plate 301 and the bottom plate 304; the side plate 302 is vertically connected to the bottom plate 304, and the inclined plate 301 and the end plate 303 are both connected to the side plate 302, and the side plate 302 is connected to the left-handed nut 10 or the right-handed nut 7. It can be seen that the fixture 3 of this embodiment uses a plurality of plates to be combined together, so as to facilitate the installation of the cutting mechanism of the busbar 4 therein.

[0044] Optionally, the side plate 302 is detachably connected to the bottom plate 304 , the inclined plate 301 and the two end plates 303 by bolts.

[0045] In order to facilitate the connection between the clamp 3 and the left-handed nut 10 and the right-handed nut 7, as shown in FIG. Figure 5 As shown, in some embodiments, a connecting plate 306 is further provided at the upper end of the side plate 302 , and the connecting plate 306 is connected to the bottom of the left-handed nut 10 or the right-handed nut 7 by bolts.

[0046] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
