Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0031] like Figure 1 As shown, an embodiment of the present invention discloses a solar cell defect detection device, comprising a support 1, a transverse conveying device 2 rotatably connected to one end face of the support 1, a detection probe 5 welded to one end face of the support 1, and a longitudinal conveying device 3 rotatably connected to one end face of the support 1. Solar cells 4 move on the transverse conveying device 2. When a solar cell 4 passes the detection probe 5, the detection probe 5 detects the solar cell 4. After detection, the transverse conveying device 2 continues to move, supporting the solar cell 4. When a solar cell 4 passes the longitudinal conveying device 3, if the detection of the solar cell 4 indicates it is a defective defective cell, the longitudinal conveying device 3 rises, lifting the defective solar cell and transporting it off the production line. This detection process is existing technology.

[0032] A guide assembly 6 is welded to one end face of the support 1. Waste solar cells transported by the longitudinal conveyor 3 are conveyed down along the guide assembly 6. A slide rail 10 is welded to one end face of the support 1. A collection box 7 is slidably connected to the slide rail 10. The collection box 7 is located below the guide assembly 6. Waste solar cells transported down by the guide assembly 6 fall into the collection box 7.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, a pair of support shells 701 are welded to opposite end faces of the collection box 7. A splash-proof component 8 is snapped onto one end face of the support shell 701. The splash-proof component 8 includes a pair of third handles 810, which are snapped onto the support shells 701. A pair of second rotating shafts 801 are welded to one end face of the third handles 810. A cover 802 is rotatably connected to the outer wall of the second rotating shafts 801. The cross-section of the cover 802 is arc-shaped. A counterweight cylinder 803 is rotatably connected to one end face of the cover 802. The counterweight cylinder 803 increases the weight on one side of the cover 802, ensuring that the center of gravity of the cover 802 and the axis of the second rotating shaft 801 are in the same vertical plane. Without external force, the cover 802 remains horizontal, allowing it to cover the opening of the collection box 7. Simultaneously, the rotatable connection between the counterweight cylinder 803 and the cover 802 changes the friction between the cover 802 and the side wall of the collection box 7 from sliding friction to rolling friction, thus reducing the frictional force between them. When waste battery cells fall from the guide assembly 6 and contact the cover 802, the small gap between the top surface of the cover 802 and the bottom surface of the guide assembly 6, located on the top surface of the collection box 7, reduces the impact force between the waste battery cells and the cover 802, preventing splashing caused by collisions. The splash guard 8 can be easily removed from the collection box 7 via the third handle 810, thereby cleaning the waste battery cells inside the collection box 7.

[0034] When the waste battery cells fall onto the cover 802, the cover 802 rotates under the influence of gravity, thereby dissipating the impact force generated by the contact between the waste battery cells and the cover 802. The waste battery cells slide down the inclined surface of the cover 802 into the collection box 7. After the waste battery cells fall into the collection box 7, the cover 802 rotates back and covers the collection box 7 again, thereby preventing the waste battery cells from colliding with the collection box 7 and causing fragments to fly onto the qualified battery cells.

[0035] Multiple sponges 804 are attached to one side of the cover 802. The sponges 804 act as a buffer to further reduce the impact of the battery waste cells on the cover 802, thereby preventing the fragments of the battery waste cells from flying.

[0036] A second handle 702 is welded to one end face of the support shell 701, and the other end face of the second handle 702 is welded together with another support shell 701. The collection box 7 can be easily moved by pulling through the support shell 701.

[0037] like Figure 4 and Figure 6As shown, a sleeve 805 is integrally formed on one end face of the cover 802. The sleeve 805 is fitted onto the second rotating shaft 801. Sliding grooves 806 are formed on the opposite end faces of the sleeve 805. A spring-loaded assembly is welded to the outer wall of the second rotating shaft 801. The spring-loaded assembly includes a second housing 807, which is welded to the outer wall of the second rotating shaft 801. A third housing 808 is slidably connected inside the second housing 807. Multiple second springs 809 are welded inside the second housing 807, and the second springs 809 are welded together with the third housing 808. When the cover 802 is in a horizontal state, one side of the sliding groove 806 abuts against the second housing 807. When the waste battery pieces fall onto the cover 802, the cover 802 rotates, causing the other side of the sliding groove 806 to abut against the third housing 808. As the rotation angle of the cover 802 increases, the side wall of the sliding groove 806 continuously squeezes the third housing 808, causing the third housing 808 to slide and compress the second spring 809. When the waste battery pieces slide off the surface of the cover 802, the battery pieces no longer exert pressure on the cover 802. Under the action of the counterweight cylinder 803, the cover 802 rotates in the opposite direction. At this time, the second spring 809 rebounds and pushes the third housing 808 to slide. The third housing 808 abuts against the side wall of the sliding groove 806, thereby increasing the rotation force of the cover 802, causing the cover 802 to quickly return to a horizontal state and cover the collection box 7 again.

[0038] The opposite end faces of the second housing 807 are provided with limiting grooves 812, and the opposite end faces of the third housing 808 are each welded with limiting blocks 811 that match the limiting grooves 812. The limiting blocks 811 are slidably connected in the groove wall of the limiting grooves 812. The limiting blocks 811 can restrict the sliding path of the third housing 808 and prevent the third housing 808 from sliding out of the second housing 807.

[0039] like Figure 7 and Figure 8 As shown, the guiding assembly 6 includes a pair of side plates 601 and a guide plate 602. The side plates 601 are welded to both sides of the guide plate 602 and are also welded to the support 1. A square hole 603 is provided on one end face of the guide plate 602, and a rotating baffle 606 is rotatably connected inside the groove wall of the square hole 603. To prevent waste battery cells from falling from the guiding assembly 6 when replacing the collection box 7, the rotating baffle 606 is rotated to a vertical position, preventing the waste battery cells from sliding along the guiding assembly 6.

[0040] A shaft hole 604 is provided on one end face of the side plate 601. The shaft hole 604 passes through a pair of side plates 601 and a guide plate 602. A first rotating shaft 605 is rotatably connected inside the hole wall of the shaft hole 604. A rotating baffle 606 is welded together with the first rotating shaft 605. A cross groove 610 is provided on one end face of one side plate 601. A first handle 607 that matches the cross groove 610 is welded to one end face of the first rotating shaft 605. The rotation of the first handle 607 can drive the rotating baffle 606 to rotate, thereby facilitating the rotation of the rotating baffle 606. At the same time, when the first handle 607 is engaged in the cross groove 610, it can prevent the first handle 607 from rotating, thereby fixing the position of the rotating baffle 606.

[0041] A first housing 608 is welded to one end face of another side plate 601. A first spring 609 is welded inside the first housing 608. The first spring 609 is fixedly connected to one end face of the first rotating shaft 605. The first spring 609 exerts a pulling force on the first rotating shaft 605, thereby causing the first handle 607 to engage in the cross groove 610. The width of the rotating baffle 606 is smaller than the width of the square hole 603, allowing the rotating baffle 606 to slide within the wall of the square hole 603. When the rotating baffle 606 needs to be rotated, pull the first handle 607 out of the groove wall of the cross slide 610. At the same time, the first rotating shaft 605 slides in the hole wall of the shaft hole 604 and the rotating baffle 606 slides in the groove wall of the square hole 603, so that the first handle 607 can rotate and the first spring 609 is stretched. Then, rotate the first handle 607 to drive the rotating baffle 606 to rotate. After the rotating baffle 606 is rotated to the position, release the first handle 607. At this time, the first spring 609 contracts, pulls the first rotating shaft 605 to slide, and drives the first handle 607 to slide into the cross slide 610, thereby fixing the position of the rotating baffle 606 and preventing the rotating baffle 606 from rotating at will.

[0042] like Figure 3 As shown, a locking block 703 is welded to the bottom end face of the collection box 7, and a locking component 9 is welded to one side end face of the slide rail 10. The locking block 703 abuts against one side end face of the locking component 9, and the locking component 9 can lock the locking block 703, thereby preventing the collection box 7 from sliding at will.

[0043] like Figure 9As shown, the locking assembly 9 includes a fourth housing 901, which is welded to one side of the slide rail 10. A third rotating shaft 902 is rotatably connected to the fourth housing 901, and a fifth housing 903 is rotatably connected to the third rotating shaft 902. A limiting wedge 904 is integrally formed on one side of the fifth housing 903. A locking block 703 abuts against the limiting wedge 904. A plurality of third springs 905 are welded to the top end of the fourth housing 901, and the third springs 905 are welded to the bottom surface of the fifth housing 903. When the collection box 7 slides down the guide assembly 6 on the slide rail 10, the bottom end face of the locking block 703 is pressed against the inclined surface of the limiting wedge block 904. The locking block 703 squeezes the limiting wedge block 904, thereby causing the fifth housing 903 to rotate and compress the third spring 905 downward. When the collection box 7 slides down to the bottom of the guide assembly 6, the locking block 703 slides past the inclined surface of the limiting wedge block 904, and the locking block 703 no longer squeezes the fifth housing 903. Under the action of the third spring 905, the fifth housing 903 rebounds. At this time, the vertical surface of the limiting wedge block 904 abuts against the side of the locking block 703, preventing the locking block 703 from sliding, thereby fixing the position of the collection box 7. When it is necessary to remove the collection box 7, step on the fifth housing 903 to make the fifth housing 903 descend. At this time, the limiting wedge block 904 also descends. The vertical surface of the limiting wedge block 904 can no longer abut against the locking block 703, and the collection box 7 can be pulled at this time.

[0044] When using, such as Figure 1 As shown, the battery cell 4 moves along the transverse conveyor 2. The detection probe 5 detects the battery cell 4. When the detected defective battery cell moves above the longitudinal conveyor 3, the longitudinal conveyor 3 rises, lifting the defective battery cell and separating it from the transverse conveyor 2. The longitudinal conveyor 3 rotates, carrying the defective battery cell into the guide assembly 6. The defective battery cell slides down the guide assembly 6 and then presses onto the sponge 804. The sponge 804 then presses against the cover. Pressure is applied to one side of 802, causing the cover 802 to lose balance and rotate, thereby reducing the collision between the cover 802 and the waste battery cells. The waste battery cells slide into the collection box 7 along the inclined surface of the cover 802. When the waste battery cells separate from the cover 802, the cover 802 is pushed by the rebound component to quickly rotate to a horizontal position and cover the collection box 7 again, thereby preventing the flying fragments generated by the collision between the waste battery cells and the collection box 7 from flying out of the collection box 7 and preventing the waste battery cells from affecting the qualified battery cells.
