[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described in more detail below by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0034] Example 1
[0035] Please refer to Figures 1-6, in the embodiments of this utility model.
[0036] A photovoltaic glass mixing and sorting machine includes a lifting platform 10 and a mounting box 2 installed on the bottom side of a ceiling 1. A servo motor 14 is fixedly connected to the top of the interior of the mounting box 2. The output shaft of the servo motor 14 is connected to a passive shaft 4 through an eccentric reduction gear. The eccentric reduction gear includes a planetary reducer 24 (the structure of the planetary reducer 24 is similar to that of a VFM20VFM multi-functional mixer, which enables the output shaft to perform planetary motion). The planetary reducer 24 is installed on the bottom side wall of the servo motor 14. The input shaft of the planetary reducer 24 is fixedly connected to the output shaft of the servo motor 14, and the output shaft of the planetary reducer 24 is fixedly connected to the passive shaft 4. The servo motor 14 can drive the passive shaft 4 to perform planetary revolution and rotation through the planetary reducer 24, which in turn can drive the wire brush 16 to rotate and rotate in a circular motion at the bottom of the screening barrel 12, thereby wrapping the photovoltaic welding ribbon copper cable in the mixture onto the wire brush 16.
[0037] The bottom end of the passive shaft 4 is connected to a disc 6 via a fixing device. A wire brush 16 is provided on the bottom side wall of the disc 6. The fixing device includes a connecting cylinder 5, which is fixedly connected to the upper side of the disc 6. Two opposing bayonet slots 18 are formed on the side wall of the connecting cylinder 5, each slot 18 being L-shaped. Two locking rods 17 are fixedly connected to both sides of the bottom end of the passive shaft 4. The passive shaft 4 engages with the two bayonet slots 18 via the two locking rods 17. The photovoltaic welding ribbon copper cable in the mixture can be wound onto the wire brush 16. When it is necessary to separate the photovoltaic welding ribbon copper cable from the wire brush 16, the two locking rods 17 at the bottom end of the passive shaft 4 can be disengaged from the two bayonet slots 18 on the connecting cylinder 5 by twisting the connecting cylinder 5, allowing the wire brush 16 to be removed.
[0038] It facilitates the removal of the photovoltaic welding strip copper cable wrapped around it;
[0039] The upper side of the lifting platform 10 is connected to the screening barrel 12 via a vibration device. The vibration device includes multiple vibration springs 11, which are fixedly connected to the bottom side wall of the screening barrel 12 in a circular array. The bottom end of each vibration spring 11 is fixedly connected to the upper side of the lifting platform 10. A vertical vibration motor 9 is provided at the center of the bottom side of the screening barrel 12. When the vibration motor 9 is started, it can make the screening barrel 12 vibrate vertically. Due to the circular array of multiple vibration springs 11 on the bottom side wall of the screening barrel 12, and the action of the wire brush 16 in the circular motion inside the screening barrel 12, the screening barrel 12 is made to oscillate around its vertical axis.
[0040] The lifting platform 10 adopts the TF100 double-shear lifting platform from the Litong Zhongyong brand. The lifting platform 10 can lift and lower the screening barrel 12. Lifting the screening barrel 12 not only facilitates the removal and replacement of the wire brush 16, but also allows for easy adjustment of the distance between the wire brush 16 and the bottom side wall of the screening barrel 12. This prevents excessive pressure from the wire brush 16 against the bottom side wall of the screening barrel 12, thus avoiding severe wear. The wire brush 16 is composed of corrugated steel wire. A battery cell opening 8 is provided at the bottom of the side wall of the screening barrel 12, with a height of approximately 200 micrometers. A battery cell discharge plate 7 is fixedly connected to the outer side of the battery cell opening 8. A spiral track 13 is fixedly connected to the inner side wall of the screening barrel 12. The bottom end of the spiral track 13 abuts against the edge of the bottom side wall of the screening barrel 12, and the upper end of the spiral track 13 penetrates through the screening barrel 12. The side wall is fixedly connected to a glass discharge plate 15.
[0041] The working principle of this utility model is as follows:
[0042] First, the mixture of glass shards, solar cells, and photovoltaic welding ribbon copper cable is fed into the top of the screening barrel 12. Then, the servo motor 14 and the vibration motor 9 are started. When the servo motor 14 drives the drive gear 3 to rotate, the driven gear 19 rotates around the drive gear 3 and rotates on its own axis. The driven gear 19 drives the wire brush 16 to rotate in a circular motion and on its own axis at the bottom of the screening barrel 12 through the driven shaft 4, so as to wrap the photovoltaic welding ribbon copper cable in the mixture around the wire brush 16.
[0043] Under the vibration of the vibrating motor 9 and the action of the wire brush 16, the battery cells in the mixture can move slowly and rhythmically at the bottom of the screening barrel 12. A battery cell inlet 8 is provided on the side wall of the bottom of the screening barrel 12.
[0044] The opening 8 only allows the solar cells to pass through (the solar cells are flat and thin sheets with a thickness of 170-180 micrometers, while the glass fragments are mostly granular with a thickness of 3000-4000 micrometers), so the solar cells can be gradually discharged from the solar cell opening 8 and flow away along the solar cell discharge plate 7;
[0045] Because the vibrating motor 9 can make the screening barrel 12 vibrate vertically, and because multiple vibrating springs 11 are arranged in a ring array on the bottom side wall of the screening barrel 12, the vertical axis of the screening barrel 12 is torsional and oscillating. The glass fragments in the screening barrel 12 are gradually raised along the spiral track 13 due to this vibration, until they are sent to the glass discharge plate 15 for discharge, thus realizing the separation of the mixture of the three.
[0046] Example 2
[0047] The difference between Example 2 and Example 1 is that...
[0048] The eccentric reduction gear includes a drive gear 3, which is fixedly connected to the output shaft of the servo motor 14. A driven gear 19 is meshed on the side wall of the drive gear 3. An internal gear ring 22 is fixedly connected to the inner ring side wall of the mounting box 2. The driven gear 19 is meshed on the inner key of the internal gear ring 22. A driven shaft 4 is fixedly connected through the central side wall of the driven gear 19. A limiting circular plate 23 is fixedly connected to the upper end of the driven shaft 4. A track ring plate 21 is fixedly connected to the inner top side wall of the mounting box 2. An annular track groove 20 is opened on the bottom side wall of the track ring plate 21. The limiting circular plate 23 is slidably connected in the annular track groove 20. When the servo motor 14 drives the drive gear 3 to rotate, the driven gear 19 can rotate around the drive gear 3 and rotate on its own axis. The driven gear 19 can drive the wire brush 16 to rotate on the screening barrel 12 via the driven shaft 4. The bottom rotates in a circular motion and rotates on its own axis to wrap the photovoltaic welding ribbon copper cable in the mixture onto the wire brush 16;
[0049] Example 3 (not shown)
[0050] The difference between Embodiment 3 and Embodiment 1 is that the fixing device includes a connecting cylinder 5, which is fixedly connected to the upper side of the disc 6. The connecting cylinder 5 has an internal thread, and the bottom end of the driven shaft 4 has an external thread, with the bottom end of the driven shaft 4 threadedly connected to the inside of the connecting cylinder 5. When it is necessary to separate the photovoltaic welding ribbon copper cable on the wire brush 16, the connecting cylinder 5 can be screwed on by the thread, causing the connecting cylinder 5 to move away from the bottom end of the driven shaft 4.
[0051] Open it to remove the wire brush 16, making it easy to remove the photovoltaic welding strip copper cable wrapped around it.
