Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and in particular to a photovoltaic frame loading platform used for applying adhesive in a photovoltaic processing production line. Background Technology

[0002] In the production process of photovoltaic modules, a photovoltaic frame feeding platform and a glue applicator are used to feed and glue the frame respectively, and then each strip frame is installed around the laminate.

[0003] In existing technology, multiple strip-shaped workpieces are first transported to a robotic arm via a belt during loading. The robotic arm then picks them up one by one and moves them to a gluing platform for gluing. However, the robotic arm's speed in picking up and moving the workpieces one by one is slow, which affects the processing efficiency and cannot load multiple frames at the same time. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a loading platform for photovoltaic frames. The loading platform for photovoltaic frames uses the weight of the workpiece itself to provide power and the cooperation of two blocking cylinders to realize the loading of multiple strip-shaped workpieces in each group one by one. It can also load multiple groups of workpieces simultaneously, thereby improving the processing efficiency and consistency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a photovoltaic frame loading platform for loading at least two photovoltaic frames, comprising: at least two loading units corresponding to the photovoltaic frames, wherein the loading units are inclined such that their front ends are lower than their rear ends, the at least two loading units are arranged at intervals in the vertical direction, and in any two adjacent loading units, the front end of the upper loading unit is located in front of the front end of the lower loading unit, each loading unit further comprising: two inclined guide bars, a storage area is formed between the two parallel and spaced guide bars, and several photovoltaic frames can be arranged inclinedly along the length of the guide bars in the storage area, and the lower surfaces of both ends of each photovoltaic frame are slidably in contact with the upper surfaces of the two guide bars;

[0006] Each of the two guide bars has a front blocking cylinder and a rear blocking cylinder installed sequentially at its front end and on both sides of the storage area. The piston rods of the two front blocking cylinders are both facing the storage area and are equipped with a blocking plate. The piston rods of the two rear blocking cylinders are both facing the storage area and are equipped with a blocking strip. When the piston rod of the front blocking cylinder is in the extended state, the rear surface of the blocking plate is pressed against the front surface of the photovoltaic frame at the foremost end. When the piston rod of the rear blocking cylinder is in the extended state, the blocking strip is embedded from its end into the photovoltaic frame at the next foremost end.

[0007] The following are further improvements to the above technical solution:

[0008] 1. In the above scheme, there are 4 feeding units for feeding 4 photovoltaic frames.

[0009] 2. In the above scheme, the four feeding units have the same tilting direction but different tilting angles.

[0010] 3. In the above scheme, the extension and retraction movements of the front blocking cylinder of each feeding unit are consistent, and the extension and retraction movements of the rear blocking cylinder of each feeding unit are consistent.

[0011] 4. In the above scheme, the two L-shaped guide bars are arranged opposite each other. The upper surface of the first folded edge of each guide bar is used to contact the lower surface of the strip-shaped workpiece, and the surface of the second folded edge of the guide bar facing the storage area is used to contact the end face of the strip-shaped workpiece.

[0012] 5. In the above scheme, a stop bar is provided above the first folded edge of each guide bar, and the lower surface of the stop bar is clearance-fitted with the end face or the upper surface of the end of the strip workpiece.

[0013] 6. In the above scheme, at least one sensor is installed on at least one guide strip and at the front end near the storage area. The sensing end of the sensor faces the storage area and is used to sense whether there is a photovoltaic frame in the corresponding storage area.

[0014] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0015] 1. The photovoltaic frame feeding platform of the present invention has feeding units that are inclined such that their front ends are lower than their rear ends. At least two feeding units are arranged vertically at intervals, and in any two adjacent feeding units, the front end of the upper feeding unit is located in front of the front end of the lower feeding unit. Each feeding unit further includes: two inclined guide bars, with a storage area formed between the two parallel and spaced guide bars. Several photovoltaic frames can be arranged inclinedly along the length of the guide bars in the storage area. The lower surfaces of both ends of each photovoltaic frame are slidably in contact with the upper surfaces of the two guide bars. A front blocking cylinder and a rear blocking cylinder are sequentially installed at the front ends of each of the two guide bars and on both sides of the storage area. Each of the two rear blocking cylinders has its piston rod facing the storage area and equipped with a blocking plate. The piston rods of the two rear blocking cylinders also face the storage area and are equipped with blocking strips. When the piston rod of the front blocking cylinder is extended, the rear surface of the blocking plate presses against the front surface of the photovoltaic frame at the foremost end. When the piston rod of the rear blocking cylinder is extended, the blocking strips embed from their ends into the photovoltaic frame at the next foremost end. Power is provided by the workpiece's own weight to achieve the orderly arrangement and automatic sliding replenishment of multiple workpieces in each group. Furthermore, the cooperation of the two blocking cylinders in each feeding unit enables automatic sorting of multiple workpieces in each group, thus achieving individual feeding of strip-shaped workpieces. Simultaneous feeding of multiple groups of workpieces can also be performed, improving processing efficiency and consistency.

[0016] 2. The photovoltaic frame loading platform of the present invention has two L-shaped guide bars arranged opposite each other. The upper surface of the first folded edge of each guide bar is used to contact the lower surface of the photovoltaic frame, and the surface of the second folded edge of the guide bar facing the storage area is used to contact the end face of the photovoltaic frame. A stop bar is provided above the first folded edge of each guide bar. The lower surface of the stop bar is in clearance fit with the end face or upper surface of the photovoltaic frame. This can realize the orderly arrangement and automatic sliding of multiple strip workpieces, and can effectively prevent the strip workpieces from flipping due to unstable center of gravity during the movement on the inclined surface, ensuring the stability and orderliness of the strip workpieces during the sequential sliding process. In addition, at least one sensor is installed on at least one guide bar and located at the front end near the storage area. The sensing end of the sensor faces the storage area and is used to sense whether there is a photovoltaic frame in the corresponding storage area. It can provide timely feedback when there are not enough workpieces in the storage area, so as to replenish the material in time and ensure the continuity and efficiency of processing.

Implementation

[0022] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0023] Example 1: A photovoltaic frame loading platform for loading at least two photovoltaic frames 100, comprising: at least two loading units corresponding to the photovoltaic frames 100, wherein the loading units are inclined such that their front ends are lower than their rear ends, the at least two loading units are spaced apart in the vertical direction, and in any two adjacent loading units, the front end of the upper loading unit is located in front of the front end of the lower loading unit, each loading unit further comprising: two inclined guide bars 2, a storage area 3 is formed between the two parallel and spaced guide bars 2, and a plurality of photovoltaic frames 100 can be sequentially inclinedly arranged in the storage area 3 along the length direction of the guide bars 2, and the lower surfaces at both ends of each photovoltaic frame 100 are slidably in contact with the upper surfaces of the two guide bars 2;

[0024] Each of the two guide bars 2 has a front blocking cylinder 4 and a rear blocking cylinder 5 installed sequentially at its front end and on both sides of the storage area 3. The piston rods of the two front blocking cylinders 4 are set towards the storage area 3 and are equipped with a blocking plate 6. The piston rods of the two rear blocking cylinders 5 are set towards the storage area 3 and are equipped with a blocking strip 7. When the piston rod of the front blocking cylinder 4 is in the extended state, the rear surface of the blocking plate 6 is pressed against the front surface of the photovoltaic frame 100 arranged at the frontmost end. When the piston rod of the rear blocking cylinder 5 is in the extended state, the blocking strip 7 is embedded from its end into the photovoltaic frame 100 arranged at the next front end.

[0025] For each feeding unit, in the initial state, the piston rod of the front blocking cylinder always remains in an extended state.

[0026] The above-mentioned feeding unit is provided in 4 units, which are used for feeding 4 photovoltaic frame 100.

[0027] The four feeding units mentioned above have the same tilt direction but different tilt angles.

[0028] The extension and retraction movements of the front blocking cylinder 4 of each of the above-mentioned feeding units are consistent, and the extension and retraction movements of the rear blocking cylinder 5 of each of the feeding units are consistent.

[0029] The two L-shaped guide bars 2 are arranged opposite each other. The upper surface of the first folded edge 201 of each guide bar 2 is used to contact the lower surface of the strip workpiece 100, and the surface of the second folded edge 202 of the guide bar 2 facing the storage area 3 is used to contact the end face of the strip workpiece 100.

[0030] The photovoltaic frames are placed sequentially from the top of the storage area, so that several photovoltaic frames are arranged in an orderly manner in the storage area. Due to the inclined setting of the guide strip, several strip-shaped workpieces in the storage area can slide down along the upper surface of the first folded edge of the guide strip under their own gravity. During this process, the upper parts of both ends of the strip-shaped workpieces are limited by the baffle strips to prevent the strip-shaped workpieces from flipping forward and falling due to the high center of gravity during the descent.

[0031] Each of the above guide strips 2 has a stop strip 11 above its first folded edge 201, and the lower surface of the stop strip 11 is in clearance fit with the end face of the strip-shaped workpiece 100.

[0032] The aforementioned baffle 11 is installed on the second folded edge 202 of the guide strip 2.

[0033] A gasket 9 extending along its length is mounted on the upper surface of the first folded edge 201 of the guide strip 2. The gasket 9 is a Teflon gasket.

[0034] The second folded edge 202 of the guide strip 2 is provided with a clearance through hole 1 for the blocking plate 6 and the blocking strip 7 to pass through.

[0035] One end of the mounting plate 12 is connected to the lower surface of the first folded edge 201 of the guide strip 2, and the other end of the mounting plate 12 extends to the side opposite to the material storage area 3 of the second folded edge 202 of the guide strip 2 and is equipped 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 mounted on the upper surface of the mounting plate 12 through a connecting seat 10, and the blocking plate 6 and the blocking strip 7 are slidably engaged with the corresponding connecting seat 10.

[0036] Example 2: A photovoltaic frame loading platform for loading at least two photovoltaic frames 100, comprising: at least two loading units corresponding to the photovoltaic frames 100, wherein the loading units are inclined such that their front ends are lower than their rear ends, the at least two loading units are spaced apart in the vertical direction, and in any two adjacent loading units, the front end of the upper loading unit is located in front of the front end of the lower loading unit, each loading unit further comprising: two inclined guide bars 2, a storage area 3 is formed between the two parallel and spaced guide bars 2, and several photovoltaic frames 100 can be sequentially inclinedly arranged in the storage area 3 along the length direction of the guide bars 2, and the lower surfaces at both ends of each photovoltaic frame 100 are slidably in contact with the upper surfaces of the two guide bars 2;

[0037] Each of the two guide bars 2 has a front blocking cylinder 4 and a rear blocking cylinder 5 installed sequentially at its front end and on both sides of the storage area 3. The piston rods of the two front blocking cylinders 4 are set towards the storage area 3 and are equipped with a blocking plate 6. The piston rods of the two rear blocking cylinders 5 are set towards the storage area 3 and are equipped with a blocking strip 7. When the piston rod of the front blocking cylinder 4 is in the extended state, the rear surface of the blocking plate 6 is pressed against the front surface of the photovoltaic frame 100 arranged at the frontmost end. When the piston rod of the rear blocking cylinder 5 is in the extended state, the blocking strip 7 is embedded from its end into the photovoltaic frame 100 arranged at the next front end.

[0038] For several strip-shaped workpieces arranged in the storage area, the photovoltaic frame located at the bottom and frontmost point stops sliding down under the stop of the blocking bar on the front blocking cylinder;

[0039] When the bottommost and frontmost photovoltaic frame needs to be fed outwards, the piston rod of the rear blocking cylinder is first extended, so that the blocking strips installed on it are inserted into the second to last photovoltaic frame from both ends, thus stopping the second photovoltaic frame and the photovoltaic frame behind it. Then the piston rod of the front blocking cylinder is retracted, so that the blocking plate removes its obstruction of the bottommost and frontmost photovoltaic frame, and it slides forward and downward under its own gravity to the subsequent receiving platform.

[0040] The extension and retraction movements of the front blocking cylinder 4 of each of the above-mentioned feeding units are consistent, and the extension and retraction movements of the rear blocking cylinder 5 of each of the feeding units are consistent.

[0041] At least one sensor 8 is installed on at least one guide bar 2 and at the front end near the storage area 3. The sensing end of the sensor 8 faces the storage area 3 and is used to sense whether there is a photovoltaic frame 100 in the corresponding storage area 3.

[0042] Within the storage area, sensors are installed to monitor the sufficiency of materials in real time. When a sensor located below the sixth photovoltaic frame from the front of the storage area fails to detect a workpiece, an alarm is triggered to remind staff to replenish materials promptly, ensuring the continuity and efficiency of processing.

[0043] The aforementioned sensor 8 is a reflective photoelectric sensor, model number Panasonic CX-441.

[0044] The aforementioned sensor 8 is mounted on the lower surface of the guide strip 2 via a connecting piece.

[0045] Two sensors 8 are provided, located directly below the second and sixth photovoltaic frame 100 counting backwards from the front end of the self-storage area 3, respectively.

[0046] The above-mentioned alarm unit is also provided, which is electrically connected to the sensor 8. When the sensor 8 detects that there is no photovoltaic frame 100 in the corresponding storage area 3, the alarm unit issues an alarm.

[0047] The working principle of this invention is as follows:

[0048] For each feeding unit, in the initial state, the piston rod of the front blocking cylinder always remains in the extended state;

[0049] The photovoltaic frames are placed sequentially from the top of the storage area, so that several photovoltaic frames are arranged in an orderly manner in the storage area. Due to the inclined setting of the guide strip, several strip-shaped workpieces in the storage area can slide down along the upper surface of the first folded edge of the guide strip under their own gravity. During this process, the upper part of both ends of the strip-shaped workpiece is limited by the stop strip to prevent the strip-shaped workpiece from flipping forward and falling due to the high center of gravity during the sliding process.

[0050] For several strip-shaped workpieces arranged in the storage area, the photovoltaic frame located at the bottom and frontmost point stops sliding down under the stop of the blocking bar on the front blocking cylinder;

[0051] Within the storage area, sensors are installed to monitor the sufficiency of materials in real time. When the sensor located below the sixth photovoltaic frame from the front of the storage area does not detect a workpiece, an alarm is issued to remind staff to replenish materials in time to ensure the continuity and efficiency of processing.

[0052] When the bottom and front photovoltaic frame needs to be fed outward, the piston rod of the rear blocking cylinder is first extended, so that the blocking strip installed on it is embedded into the second to last photovoltaic frame from both ends, thus stopping the second photovoltaic frame and the photovoltaic frame behind it. Then the piston rod of the front blocking cylinder is retracted, so that the blocking plate removes its obstruction of the bottom and front photovoltaic frame, and it slides forward and downward under its own gravity to the subsequent receiving platform.

[0053] This process is repeated to achieve automatic feeding of each strip-shaped workpiece.

[0054] For the photovoltaic frame loading platform, each loading unit performs the above operation synchronously, so that the photovoltaic frames at the bottom and front of each loading platform slide forward and downward under their own gravity to the subsequent receiving platform, thereby realizing the synchronous loading of multiple photovoltaic frames.

[0055] The aforementioned photovoltaic frame loading platform utilizes the workpiece's own weight to power the orderly arrangement and automatic sliding replenishment of multiple workpieces in each group. Furthermore, the coordinated operation of two blocking cylinders in each loading unit enables automatic sorting of these multiple workpieces, allowing for the individual loading of strip-shaped workpieces. Simultaneous loading of multiple groups of workpieces can also be achieved, improving processing efficiency and consistency. Moreover, it not only enables the orderly arrangement and automatic sliding of multiple strip-shaped workpieces but also effectively prevents them from overturning due to instability during movement on an inclined surface, ensuring stability and orderliness during the sequential sliding process. Additionally, it provides timely feedback when there are insufficient workpieces in the storage area, facilitating timely replenishment and ensuring processing continuity and efficiency.

[0056] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
