Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and in particular to a multi-frame synchronous feeding device for applying adhesive in a photovoltaic processing production line. Background Technology

[0002] When installing photovoltaic modules, the laminates and frames need to be glued to the frames before they can be installed with the laminates. The process of applying glue involves steps such as loading, unloading, and applying the glue to the frames.

[0003] Existing technology typically uses a belt to transport photovoltaic frames to a robotic arm for loading. The robotic arm then picks them up one by one and transports them to a gluing platform for gluing. However, belt transport cannot sort frames individually or load multiple sets of frames simultaneously. Furthermore, the frames may shift during transport, making it impossible to calibrate the workpiece position, which can easily affect the positional accuracy of the frames during transport. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-frame synchronous feeding device. The multi-frame synchronous feeding device uses the workpiece's own weight to provide power and the cooperation of two blocking cylinders to sort photovoltaic frames one by one to facilitate subsequent material handling operations. It can also feed multiple sets of workpieces synchronously and can also perform centering calibration on the workpieces sorted to the receiving seat to improve the positional accuracy of each workpiece during the flow process.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a multi-frame synchronous feeding device for feeding at least two photovoltaic frames, comprising: at least two feeding units corresponding to the photovoltaic frames, wherein the feeding units are inclined such that their front end is lower than their rear end, the at least two feeding units are arranged at intervals in the vertical direction, and in any two adjacent feeding units, the front end of the feeding unit located above is located in front of the front end of the feeding unit located below, each feeding 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 in sequence along the length direction 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 receiving seat on its front side. The bearing part, stop part and limiting part of the receiving seat intersect perpendicularly to form a receiving area for the end of the photovoltaic frame to be embedded. The upper surface of the bearing part, which is used to contact the lower surface of the photovoltaic frame, is flush with the upper surface of the guide bar. The stop part is used to contact the front surface of the photovoltaic frame. The limiting part is set towards the end faces of both ends of the photovoltaic frame.

[0007] 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 all facing the storage area and are equipped with a blocking plate. The piston rods of the two rear blocking cylinders are all facing the storage area and are equipped with a blocking bar. A receiving cylinder is provided on the front side of the front blocking cylinder. The piston rod of the receiving cylinder is connected to the surface of the limiting part of the receiving seat opposite to the photovoltaic frame.

[0008] 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 the end into the photovoltaic frame at the next foremost end. When the piston rod of the receiving cylinder is in the extended state, the limiting part of the receiving seat is pressed against the end faces of both ends of the photovoltaic frame.

[0009] The following are further improvements to the above technical solution:

[0010] 1. In the above scheme, the receiving seat is mounted on the guide strip via a connecting piece.

[0011] 2. In the above scheme, the receiving cylinder is mounted on the guide bar via a mounting base.

[0012] 3. In the above scheme, an elastic pad is installed on the surface of the stop part of the receiving seat facing the photovoltaic frame.

[0013] 4. In the above scheme, the elastic gasket is an urethane gasket.

[0014] 5. In the above scheme, there are 4 feeding units for feeding 4 photovoltaic frames.

[0015] 6. In the above scheme, the four feeding units have the same tilting direction but different tilting angles.

[0016] 7. 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.

[0017] 8. 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 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.

[0018] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0019] This invention relates to a multi-frame synchronous feeding device, wherein the feeding units 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 of the two guide bars of the feeding unit has a receiving seat on its front side. The upper surface of the bearing part, which contacts the lower surface of the photovoltaic frame, is flush with the upper surface of the guide bar. The stop part contacts the front surface of the photovoltaic frame, and the limiting part faces the end faces of both ends of the photovoltaic frame. 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. The piston rods of the two front blocking cylinders face the storage area and are equipped with a blocking plate. The piston rods of the two rear blocking cylinders face the storage area and are equipped with a blocking bar. A receiving cylinder is located in front of the front blocking cylinder, and the piston rod of this receiving cylinder is positioned in front of the receiving seat. The surfaces of the parts opposite to the photovoltaic frame are connected. 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 frontmost end. When the piston rod of the rear blocking cylinder is in the extended state, the blocking strip is embedded from the end into the photovoltaic frame at the next frontmost end. When the piston rod of the receiving cylinder is in the extended state, the limiting part of the receiving seat is pressed against the end faces of both ends of the photovoltaic frame. The workpiece provides power by its own weight, which simultaneously realizes the orderly arrangement and automatic sliding of multiple workpieces in each group. The cooperation of the two blocking cylinders in each feeding unit realizes the automatic sorting of multiple workpieces in each group and makes the workpiece at the frontmost end automatically slide onto the receiving seat. This realizes the sorting of photovoltaic frames one by one to facilitate subsequent material handling operations. Multiple groups of workpieces can be fed simultaneously to improve processing efficiency and consistency. The workpieces sorted onto the receiving seat can also be centered and calibrated to improve the positional accuracy of each workpiece during the flow process. Attached Figure Description

Implementation

[0026] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0027] Example 1: A multi-frame synchronous feeding device for feeding at least two photovoltaic frames 100, comprising: at least two feeding units corresponding to the photovoltaic frames 100, wherein the feeding units are inclined such that their front ends are lower than their rear ends, the at least two feeding units are spaced apart in the vertical direction, 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 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 arranged inclinedly along the length direction of the guide bars 2 in the storage area 3, 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;

[0028] Each of the two guide bars 2 has a receiving seat 8 on its front side. The supporting part 81, the stop part 82 and the limiting part 83 of the receiving seat 8 intersect perpendicularly to form a receiving area for the end of the photovoltaic frame 100 to be embedded. The upper surface of the supporting part 81, which is used to contact the lower surface of the photovoltaic frame 100, is flush with the upper surface of the guide bar 2. The stop part 82 is used to contact the front surface of the photovoltaic frame 100. The limiting part 83 is set towards the end faces of both ends of the photovoltaic frame 100.

[0029] 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 bar 7. A receiving cylinder 1 is provided on the front side of the front blocking cylinder 4. The piston rod of the receiving cylinder 1 is connected to the surface of the limiting part 83 of the receiving seat 8 opposite to the photovoltaic frame 100.

[0030] 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 front end. When the piston rod of the rear blocking cylinder 5 is in the extended state, the blocking strip 7 is embedded from the end into the photovoltaic frame 100 arranged at the second front end. When the piston rod of the receiving cylinder 1 is in the extended state, the limiting part 83 of the receiving seat 8 is pressed against the end faces of both ends of the photovoltaic frame 100.

[0031] 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. Under its own gravity, it slides forward and downward onto the receiving seat and is located between the two receiving seats.

[0032] The aforementioned receiving seat 8 is mounted on the guide strip 2 via a connecting piece.

[0033] An elastic pad 84 is installed on the surface of the stop portion 82 of the receiving seat 8 facing the photovoltaic frame 100. This pad can dampen and buffer the workpiece that slides into the receiving seat under its own weight, thus preventing the workpiece from being damaged due to excessive force.

[0034] The aforementioned elastic gasket 84 is an urethane gasket.

[0035] The above-mentioned feeding unit is provided in 4 units, which are used for feeding 4 photovoltaic frame 100.

[0036] The four feeding units mentioned above have the same tilt direction but different tilt angles.

[0037] 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.

[0038] 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 photovoltaic frame 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 photovoltaic frame 100.

[0039] 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.

[0040] Example 2: A multi-frame synchronous feeding device for feeding at least two photovoltaic frames 100, comprising: at least two feeding units corresponding to the photovoltaic frames 100, wherein the feeding units are inclined such that their front ends are lower than their rear ends, the at least two feeding units are spaced apart in the vertical direction, 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 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 arranged inclinedly along the length direction of the guide bars 2 in the storage area 3, 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;

[0041] Each of the two guide bars 2 has a receiving seat 8 on its front side. The supporting part 81, the stop part 82 and the limiting part 83 of the receiving seat 8 intersect perpendicularly to form a receiving area for the end of the photovoltaic frame 100 to be embedded. The upper surface of the supporting part 81, which is used to contact the lower surface of the photovoltaic frame 100, is flush with the upper surface of the guide bar 2. The stop part 82 is used to contact the front surface of the photovoltaic frame 100. The limiting part 83 is set towards the end faces of both ends of the photovoltaic frame 100.

[0042] 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 bar 7. A receiving cylinder 1 is provided on the front side of the front blocking cylinder 4. The piston rod of the receiving cylinder 1 is connected to the surface of the limiting part 83 of the receiving seat 8 opposite to the photovoltaic frame 100.

[0043] For each feeding unit, in the initial state, the piston rod of the front blocking cylinder always remains in the extended state;

[0044] 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;

[0045] The piston rods of two oppositely positioned receiving cylinders are simultaneously converted from the retracted state to the extended state to clamp and center the workpiece located between them, so as to ensure the positional accuracy of the workpiece. Afterwards, the workpiece can be removed from the receiving seat by an external receiving platform (such as a robot).

[0046] 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 front end. When the piston rod of the rear blocking cylinder 5 is in the extended state, the blocking strip 7 is embedded from the end into the photovoltaic frame 100 arranged at the second front end. When the piston rod of the receiving cylinder 1 is in the extended state, the limiting part 83 of the receiving seat 8 is pressed against the end faces of both ends of the photovoltaic frame 100.

[0047] The aforementioned receiving cylinder 1 is mounted on the guide bar 2 via a mounting base.

[0048] 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.

[0049] 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 photovoltaic frame 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 photovoltaic frame 100.

[0050] The aforementioned stop bar 15 is installed on the second folded edge 202 of the guide bar 2.

[0051] 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.

[0052] The second folded edge 202 of the guide strip 2 is provided with a clearance through hole 17 for the blocking plate 6 and the blocking strip 7 to pass through.

[0053] One end of the mounting plate 16 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 16 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 16 through a connecting seat 10, and the blocking plate 6 and the blocking strip 7 are slidably engaged with the corresponding connecting seat 10.

[0054] The working principle of this invention is as follows:

[0055] For each feeding unit, in the initial state, the piston rod of the front blocking cylinder always remains in the extended state;

[0056] The photovoltaic frames are placed into the storage area one by one from the top, so that several photovoltaic frames are arranged in an orderly manner in the storage area. Due to the inclined setting of the guide bar, several strip-shaped workpieces in the storage area can slide down along the upper surface of the first folded edge of the guide bar under their own gravity.

[0057] 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;

[0058] 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 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 bottommost and frontmost photovoltaic frame. Under its own gravity, it slides forward and downward onto the receiving seat and is located between the two receiving seats. At this time, the piston rods of the two opposite receiving cylinders are simultaneously changed from the retracted state to the extended state to clamp and center the workpiece located between them to ensure the positional accuracy of the workpiece. Afterwards, the workpiece can be removed from the receiving seat by an external receiving platform (such as a robot).

[0059] This process is repeated to achieve automatic feeding of each strip-shaped workpiece.

[0060] For the multi-frame synchronous feeding device, each feeding unit performs the above operation synchronously, so that the photovoltaic frames at the bottom and front of each feeding platform slide forward and downward on the receiving seat under their own gravity, thereby realizing the synchronous feeding of multiple photovoltaic frames.

[0061] The aforementioned multi-frame synchronous feeding device uses the workpiece's own weight to provide power, simultaneously achieving the orderly arrangement and automatic sliding replenishment of multiple workpieces in each group. Furthermore, the cooperation of two blocking cylinders in each feeding unit enables automatic sorting of multiple workpieces in each group, allowing the workpiece at the forefront to automatically slide onto the receiving seat. This achieves the individual sorting of photovoltaic frames for subsequent material handling operations. It also allows for the synchronous feeding of multiple groups of workpieces, improving processing efficiency and consistency. Additionally, it enables centering and calibration of the workpieces sorted onto the receiving seat, improving the positional accuracy of each workpiece during the transfer process.

[0062] 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.
