Description

Technical Field

[0002] Photovoltaic frame refers to the frame structure material used to fix and seal photovoltaic modules, and is an important component of photovoltaic modules. Its main functions include protecting the internal structure of the module, improving the mechanical strength and weather resistance of the module, and extending the service life of the module. When making photovoltaic frames, welding is required at the corners of the frame. After welding, grinding equipment is required to grind the welding points. The grinding equipment in the prior art puts the scraps into the grinding box, twists the second operating lever to tighten and fix the scraps, and then starts the motor to rotate the grinding sheet. The user presses the third operating lever to grind the scraps. When the user adjusts the angle of the box, the first operating lever is pulled to separate the clamping block from the clamping slot, and then the first operating lever is rotated to change the grinding angle of the scraps. After the angle is adjusted, the first operating lever is pushed again to embed the clamping block into the clamping slot, so that the device is fixed, so as to solve the problem that manual grinding is harmful to the human body and large machines are difficult to control the angle.

[0019] The implementation principle of the aluminum profile photovoltaic frame corner grinding device of the embodiment of the present invention is as follows: first, when the photovoltaic frame body 7 to be polished is placed on the two placement plates 6 at the top of the fixing seat 31, the rocker 45 can be used to rotate the bidirectional screw 42 on the fixing seat 31, and the two movable plates 43 move synchronously toward each other on the rotating bidirectional screw 42, thereby driving the limit bar 44 to move toward the side close to the photovoltaic frame body 7, so as to adjust the photovoltaic frame body 7 to the middle position on the placement plate 6, and then, the electric telescopic rod 38 is started to drive the second driving plate 37 to move toward the side close to the bracket 2.

At the same time, the motor 14 on the fixed frame 13 is started to drive the second gear 15 to rotate, and through the two first gears 11, the second gear 15 is driven to rotate. The two grinding discs 12 rotate. When the two rotating grinding discs 12 rotate and grind at the two corners on the photovoltaic frame body 7, the shielding cover 23 is put on the corners of the photovoltaic frame body 7 to shield the generated debris, and the shielded debris falls into the collection frame 25 for collection, and the downward movement of the shielding cover 23 drives the bottom end of the stabilizing rod 29 to be inserted into the stabilizing groove 30 to increase the stability of the grinding and avoid the photovoltaic frame body 7 from rotating. After grinding, the cylinder 9 drives the lifting plate 47 to move upward, driving one end of the insertion rod 18 to slide from the vertical groove 21 to the first driving groove 20 In the process, the rod 18 squeezes the groove wall of the first driving groove 20 to drive the rotating column 5 to rotate, thereby rotating the photovoltaic frame body 7. When one end of the rod 18 slides to the highest position in the first driving groove 20, the lifting plate 47 moves downward, driving one end of the rod 18 to slide downward in the first driving groove 20 to the top of the vertical groove 21, and continues to drive the photovoltaic frame body 7 to rotate, so that the other two frames of the photovoltaic frame body 7 can be smoothly rotated to the bottom of the two grinding discs 12, and then automatically cut the photovoltaic frame body 7 for corner grinding, which greatly improves the grinding work efficiency.
