The piston rods of the two front blocking cylinders 4 are arranged toward the material storage area 3 and are installed with a blocking plate 6. The piston rods of the two rear blocking cylinders 5 are arranged toward the material storage area 3 and are installed with a blocking bar 7. When the piston rods of the front blocking cylinders 4 are in an extended state, the rear side surface of the blocking plate 6 is in compression contact with the front side surface of the photovoltaic frame 100 arranged at the front end. When the piston rods of the rear blocking cylinders 5 are in an extended state, the blocking bar 7 is embedded from the end into the photovoltaic frame 100 arranged at the second front end. For each loading unit, in the initial state, the piston rod of the front blocking cylinder always remains in an extended state;.

[0018] There are four loading units for loading four photovoltaic frames 100 .

[0019] The four loading units have the same inclination direction but different inclination angles.

[0020] The telescopic action of the front blocking cylinder 4 of each of the above-mentioned feeding units is consistent, and the telescopic action of the rear blocking cylinder 5 of each of the above-mentioned feeding units is consistent.

[0021] The two L-shaped guide strips 2 are arranged opposite to each other, and the upper surface of the first folded edge portion 201 of each guide strip 2 is used to contact the lower surface of the strip workpiece 100, and the surface of the second folded edge portion 202 of the guide strip 2 facing the material storage area 3 is used to contact the end surface of the strip workpiece 100; The photovoltaic frames are placed in sequence from the upper end of the storage area, so that several photovoltaic frames are arranged in sequence and in an orderly manner in the storage area. Because of the inclined setting of the guide bar, several strip-shaped workpieces in the storage area can slide downward along the upper surface of the first folded edge of the guide bar under the action of their respective gravity. In this process, the upper parts of the two ends of the strip-shaped workpiece are limited by the baffle bar to prevent the strip-shaped workpiece from flipping forward and falling due to the excessively high center of gravity during the sliding process.

[0022] A stopper bar 11 is disposed above the first folded edge portion 201 of each guide bar 2 , and the lower surface of the stopper bar 11 is gap-matched with the end surface of the strip-shaped workpiece 100 .

[0023] The blocking strip 11 is installed on the second folded edge portion 202 of the guide strip 2 .

[0024] A gasket 9 extending along the length direction is installed on the upper surface of the first folded edge portion 201 of the guide strip 2, and the gasket 9 is a Teflon gasket.

[0026] One end of the above-mentioned mounting plate 12 is connected to the lower surface of the first folded edge portion 201 of the guide bar 2, and the other end of the mounting plate 12 extends to the second folded edge portion 202 of the guide bar 2 opposite to the side of the material storage area 3 and is installed with the front blocking cylinder 4 and the rear blocking cylinder 5; each of the front blocking cylinder 4 and the rear blocking cylinder 5 is respectively installed on the upper surface of the mounting plate 12 through a connecting seat 10, and the blocking plate 6 and the blocking bar 7 are slidably matched with the corresponding connecting seat 10.

[0027] Embodiment 2: A loading platform for a photovoltaic frame, used for loading at least two photovoltaic frames 100, comprising: at least two loading units corresponding to the photovoltaic frames 100, the loading units being tilted so that their front ends are lower than their rear ends, at least two of the loading units being spaced apart in the vertical direction, and in any two adjacent loading units, the front ends of the loading units disposed above are located in front of the front ends of the loading units disposed below, each of the loading units further comprising: two tilted guide bars 2, a material storage area 3 being formed between the two parallel and spaced guide bars 2, a plurality of photovoltaic frames 100 being tiltedly arranged in sequence in the material storage area 3 along the length direction of the guide bars 2, and the lower surfaces at both ends of each of the photovoltaic frames 100 being in slidable contact with the upper surfaces of the two guide bars 2 correspondingly; A front blocking cylinder 4 and a rear blocking cylinder 5 are installed in sequence at the front ends of the two guide bars 2 and on both sides of the material storage area 3. The piston rods of the two front blocking cylinders 4 are arranged toward the material storage area 3 and are installed with a blocking plate 6. The piston rods of the two rear blocking cylinders 5 are arranged toward the material storage area 3 and are installed with a blocking bar 7. When the piston rods of the front blocking cylinders 4 are in an extended state, the rear side surface of the blocking plate 6 is in compression contact with the front side surface of the photovoltaic frame 100 arranged at the front end. When the piston rods of the rear blocking cylinders 5 are in an extended state, the blocking bar 7 is embedded from the end into the photovoltaic frame 100 arranged at the second front end. For a plurality of bar-shaped workpieces arranged in the storage area, the photovoltaic frame located at the bottom and the front end stops sliding down under the stopper of the blocking bar on the front blocking cylinder; When the bottom and frontmost photovoltaic frame needs to be output for feeding, the piston rod of the rear blocking cylinder is first driven to extend, so that the blocking strips installed thereon are respectively embedded in the second-to-last photovoltaic frame at the front end from both ends, so as to stop the second photovoltaic frame and the photovoltaic frame behind it, and then the piston rod of the front blocking cylinder is driven to contract, so that the blocking plate removes the blocking of the bottom and frontmost photovoltaic frame, and it slides forward and downward to the subsequent material receiving platform under the action of its own gravity.

[0028] The telescopic action of the front blocking cylinder 4 of each of the above-mentioned feeding units is consistent, and the telescopic action of the rear blocking cylinder 5 of each of the above-mentioned feeding units is consistent.

[0029] At least one sensor 8 is installed on the at least one guide bar 2 and located near the front end of the material storage area 3. The sensing end of the sensor 8 faces the material storage area 3 and is used to sense whether there is a photovoltaic frame 100 in the corresponding material storage area 3. In the material storage area, sensors are installed to detect in real time whether there is enough material in the material storage area. When the sensor installed under the sixth photovoltaic frame from the front end of the material storage area does not detect the workpiece, a corresponding alarm is issued to remind the staff to replenish the material in time to ensure the continuity and efficiency of the processing.

[0030] The sensor 8 is a reflective photoelectric sensor, and its model is Panasonic CX-441.

[0031] The sensor 8 is mounted on the lower surface of the guide bar 2 via a connecting piece.

[0032] There are two sensors 8 , which are respectively arranged directly below the second and sixth photovoltaic frames 100 counted backward from the front end of the material storage area 3 .

[0033] The above-mentioned device is also provided with an alarm unit electrically connected to the sensor 8 , and when the sensor 8 senses that there is no photovoltaic frame 100 in the corresponding material storage area 3 , the alarm unit sends out an alarm.

[0034] The working principle of the present invention is as follows: For each loading unit, in the initial state, the piston rod of the front blocking cylinder always remains in an extended state; The photovoltaic frames are sequentially placed from the upper end of the material storage area, so that a plurality of photovoltaic frames are sequentially arranged in the material storage area in an orderly manner. Because of the inclined setting of the guide bar, a plurality of bar-shaped workpieces in the material storage area can slide down along the upper surface of the first folded edge portion of the guide bar under the action of their own gravity. In this process, the upper parts of both ends of the bar-shaped workpiece are limited by the blocking bar to prevent the bar-shaped workpiece from flipping forward and falling due to the excessively high center of gravity during the sliding process. For a plurality of bar-shaped workpieces arranged in the storage area, the photovoltaic frame located at the bottom and the front end stops sliding down under the stopper of the blocking bar on the front blocking cylinder; In the material storage area, the sensors are used to detect whether the material in the material storage area is sufficient in real time. When the sensor set under the sixth photovoltaic frame from the front end of the material storage area does not detect the workpiece, a corresponding alarm is issued to remind the staff to replenish the material in time to ensure the continuity and efficiency of processing; When the bottom and front photovoltaic frame needs to be fed outward, the piston rod of the rear blocking cylinder is first driven to extend, so that the blocking strips installed thereon are respectively embedded in the second-to-last photovoltaic frame at the front from both ends, so as to stop the second photovoltaic frame and the photovoltaic frame behind it, and then the piston rod of the front blocking cylinder is driven to contract, so that the blocking plate cancels the blocking of the bottom and front photovoltaic frame, and then it slides forward and downward to the subsequent material receiving platform under the action of its own gravity; This reciprocating process realizes automatic loading of strip-shaped workpieces one by one.

[0035] For the loading platform of the photovoltaic frame, each loading unit thereof performs the above operations synchronously, so that the photovoltaic frame located at the bottom and the front end on each loading platform slides forward and downward to the subsequent receiving platform under the action of its own gravity at the same time, thereby realizing the synchronous loading of multiple photovoltaic frames.

[0036] The loading platform of the photovoltaic frame mentioned above provides power through the deadweight of the workpieces to realize the orderly arrangement and automatic sliding and replenishment of each group of multiple workpieces, and realizes automatic sorting of each group of multiple workpieces through the cooperation of the two blocking cylinders in each loading unit, thereby realizing the loading of strip workpieces one by one, and can also load multiple groups of workpieces synchronously, thereby improving the efficiency and consistency of processing; further, it can realize the orderly arrangement and automatic sliding of multiple strip workpieces, and can effectively prevent the strip workpieces from flipping over due to unstable center of gravity during movement on the inclined surface, thereby ensuring the stability and orderliness of the strip workpieces in the process of sliding down in sequence, and can give timely feedback when there are insufficient workpieces in the storage area, so as to facilitate timely replenishment and ensure the continuity and efficiency of processing.
