Description

Technical Field

[0001] This utility model relates to the technical field of transportation equipment, and in particular to a carrier plate conveying device based on a double-speed chain. Background Technology

[0002] As photovoltaic module manufacturing technology continues to develop towards higher power and larger size, there is a demand for automated transportation of large-size and heavy photovoltaic substrates.

[0003] In related technologies, for heavy-load transmission of such large plates, roller conveyors consisting of multiple sets of rollers arranged in parallel are usually used, or wide chain plates are set on the conveyor line for support and traction.

[0004] However, the roller conveyor method described above is prone to roller surface deflection, drive slippage, or asynchronous start and stop when facing heavy load photovoltaic panels, which can cause the panels to deviate or vibrate. As for the wide chain conveyor method, the chain joints wear out quickly under heavy loads, and the entire conveying surface is in rigid contact. At the moment of start and stop, it is easy to generate static friction impact with the panel, which may damage the surface of the panel or the precision workpieces on it. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a carrier plate conveying device based on a double-speed chain, thereby solving the problem of conveying large carrier plates under heavy load conditions and achieving high conveying efficiency.

[0006] The technical solution adopted in this utility model is as follows: A carrier conveyor based on a double-speed chain includes: A conveying assembly, comprising a first conveying track, a second conveying track, and a third conveying track arranged sequentially along the width direction, wherein the first conveying track is located between the second and third conveying tracks; The first, second, and third conveying tracks are arranged in parallel. The first, second, and third conveying tracks are all equipped with double-speed chains, and the top surface of the double-speed chains abuts against the carrier plate and transports the carrier plate in the length direction. A guide wheel is provided on the exit side of at least one of the first conveying track, the second conveying track, and the third conveying track.

[0007] As a further improvement to the above technical solution: In one embodiment, the first conveying track includes a first support frame, on one side of the first support frame in the width direction, a drive motor is mounted on the first support frame, the output end of the drive motor is connected to an output pulley, the output pulley is connected to a transmission pulley via a belt, the transmission pulley is fixedly connected to and coaxially arranged with a transmission shaft; a first gear is mounted on the transmission shaft, the first gear is located on one side of the first support frame in the length direction, and a second gear is arranged on the other side of the first support frame in the length direction, the first gear and the second gear drive the speed-multiplying chain.

[0008] In one embodiment, the second conveying track includes a second support frame. The second support frame has a first limiting plate on the side away from the first conveying track in the width direction. The second support frame has a third gear on one side in the length direction, and the third gear is fixedly connected to the drive shaft. The second support frame has a fourth gear on the other side in the length direction. The speed-multiplying chain is driven by the third gear and the fourth gear.

[0009] In one embodiment, the third conveying track includes a third support frame. The third support frame has a second limiting plate on the side away from the first conveying track in the width direction. The third support frame has a fifth gear on one side in the length direction, and the fifth gear is fixedly connected to the drive shaft. The third support frame has a sixth gear on the other side in the length direction. The speed-multiplying chain is driven by the fifth gear and the sixth gear.

[0010] In one embodiment, friction strips are added to the sides of the first limiting plate and the second limiting plate near the first conveying track.

[0011] In one embodiment, the speed-multiplying chain includes a plurality of rollers and chain plates, the plurality of rollers being interconnected via the chain plates.

[0012] In one embodiment, the bottoms of the first, second, and third conveying tracks are connected by reinforcing rods to enhance the overall structural strength.

[0013] In one embodiment, the speed-multiplying chain has chain guide blocks on both sides along its length. The chain guide blocks have a fan-shaped structure and are used to tension and guide the speed-multiplying chain.

[0014] In one embodiment, there are multiple guide wheels, which are respectively disposed on the outlet side of the first conveying track, the second conveying track and the third conveying track, for guiding the conveying direction of the carrier plate.

[0015] In one embodiment, the speed-multiplying chains of the first, second, and third conveying tracks are synchronously driven by the same drive motor via a transmission shaft.

[0016] The beneficial effects of this utility model are as follows: This utility model has a compact structure. By adopting a parallel layout of three conveying tracks and applying a double-speed chain to all tracks, the device distributes the weight of the heavy-duty plate to three load-bearing and transmission support points. This effectively avoids the downward deflection that may occur on a single wide track or roller conveyor due to concentrated force, ensuring that the plate remains stable during the conveying process and preventing the plate from deviating or vibrating due to structural deformation.

[0017] This utility model also has the following advantages: This invention employs a single drive motor to synchronously drive three double-speed chains on three tracks via a transmission shaft. Through the mechanical synchronization design of the transmission shaft linkage, the speed of each double-speed chain is guaranteed to be consistent during start-up, stopping, and operation, completely eliminating the problems of plate jamming, friction, or vibration caused by asynchrony. At the same time, the "roller structure" of the double-speed chain itself rolls forward on the chain guide rail, resulting in lower running resistance, lower wear, and longer service life compared to the sliding friction of wide chain plates. This utility model has limiting plates on both sides, which can form a natural lateral guidance and constraint on the carrier plate, further preventing it from deviating; at the same time, friction strips are added, and the friction strips made of materials with a suitable coefficient of friction make it difficult for static friction impact to be generated on the bottom surface of the carrier plate at the moment of start-up and stop. The guide wheel added to the outlet side of this utility model can smoothly guide and transition the conveying direction of the carrier plate, ensuring that it enters the next station accurately and smoothly, thereby improving the continuity and automation of the entire conveyor line.

[0030] like Figures 1-5 The accompanying drawing shows a structural schematic diagram of a carrier plate conveying device based on a double-speed chain according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0031] This application provides a carrier plate conveying device based on a double-speed chain, including a conveying assembly 100. The conveying assembly 100 is composed of a first conveying track 110, a second conveying track 120 and a third conveying track 130 arranged in parallel along the width direction. The first conveying track 110 is located in the middle of the second conveying track 120 and the third conveying track 130 to balance the weight of the carrier plate 200.

[0032] In some embodiments, a double-speed chain 140 is provided on the first conveying track 110, the second conveying track 120, and the third conveying track 130. The top surface of the double-speed chain 140 is in direct contact with the bottom surface of the carrier plate 200, and the carrier plate 200 is smoothly conveyed in the length direction through the continuous movement of the chain. A guide wheel 150 is provided on the exit side of at least one conveying track (preferably the exit side of all tracks in this embodiment) to guide the conveying direction of the carrier plate 200 and ensure its smooth transition to the next station.

[0033] In some embodiments, the specific structure of the first conveying track 110 includes a first support frame 111, which is made of rigid material to provide a stable support foundation; a drive motor 112 is installed on one side of the width direction of the first support frame 111, and the output end of the drive motor 112 is fixedly connected to the output pulley 113. The output pulley 113 is connected to the transmission pulley 114 via a belt (not marked in the figure), and the transmission pulley 114 is fixed coaxially with the transmission shaft 115.

[0034] When the drive motor 112 starts, the output pulley 113 drives the transmission pulley 114 via a belt, which in turn drives the transmission shaft 115 to rotate. A first gear 116 is mounted on the transmission shaft 115, located on one side of the length direction of the first support frame 111; a second gear 117 is arranged on the other side of the length direction of the first support frame 111. The first gear 116 and the second gear 117 mesh together and drive the speed-multiplying chain 140 to achieve power transmission.

[0035] In some embodiments, the second conveying track 120 includes a second support frame 121, and a first limiting plate 122 is provided on the side of the second support frame 121 that is away from the first conveying track 110 in the width direction; the first limiting plate 122 is used to laterally limit the carrier plate 200 to prevent it from deviating. A third gear 123 is provided on one side of the second support frame 121 along its length, and the third gear 123 is fixedly connected to the drive shaft 115; a fourth gear 124 is provided on the other side along its length; the third gear 123 and the fourth gear 124 transmit the power of the drive shaft 115 to the double speed chain 140 of the second conveying track 120 through meshing with the double speed chain 140, ensuring that it runs synchronously with the first conveying track 110.

[0036] In some embodiments, the third conveying track 130 includes a third support frame 131, and the third support frame 131 is provided with a second limiting plate 132 on the side of the third support frame 131 that is away from the first conveying track 110 in the width direction. The second limiting plate 132 is symmetrically arranged with the first limiting plate 122, and together they constrain the lateral movement of the carrier plate 200.

[0037] A fifth gear 133 is provided on one side of the third support frame 131 along its length, and the fifth gear 133 is fixedly connected to the drive shaft 115; a sixth gear 134 is provided on the other side along its length. The fifth gear 133 and the sixth gear 134 drive the speed-multiplying chain 140 of the third conveying track 130 to achieve synchronous movement of the three tracks.

[0038] To further improve the limiting effect, friction strips (not shown in the figure) can be added to the sides of the first limiting plate 122 and the second limiting plate 132 near the first conveying track 110. These strips are used to increase the friction with the carrier plate 200 at the moment of start-up and stop, reduce sliding impact, and enhance stability.

[0039] In some embodiments, the double-speed chain 140 consists of a plurality of rollers 141 and chain plates 142, with the rollers 141 being hinged to each other via the chain plates 142. The rollers 141 roll forward under the guidance of the chain guide block 160, and their top surfaces form rolling friction contact with the carrier plate 200, effectively reducing wear and impact.

[0040] To enhance the overall structural strength, the bottoms of the first conveying track 110, the second conveying track 120, and the third conveying track 130 are interconnected by reinforcing rods 300. The reinforcing rods 300 are made of metal and are horizontally fixed between the supporting frames to form a rigid frame structure, preventing deformation or vibration caused by heavy loads.

[0041] In some embodiments, the double-speed chain 140 is provided with chain guide blocks 160 on both sides in the length direction. The chain guide blocks 160 have a fan-shaped structure and are used to tension and guide the double-speed chain 140 to prevent the chain from deviating or derailing. The fan-shaped design allows the chain to transition smoothly in the bending section and reduces friction loss.

[0042] In one specific embodiment, multiple guide wheels 150 are provided, located on the exit side of the first conveying track 110, the second conveying track 120 and the third conveying track 130 respectively, to provide lateral guidance when the carrier plate 200 exits, ensuring the accuracy of the conveying direction.

[0043] In this device, the speed-multiplying chains 140 of the first conveying track 110, the second conveying track 120, and the third conveying track 130 are synchronously driven by the same drive motor 112 via a transmission shaft 115. The transmission shaft 115 passes through the three tracks and is fixedly connected by the first gear 116, the third gear 123, and the fifth gear 133, achieving unified power distribution and ensuring the speed consistency of each speed-multiplying chain 140, thus avoiding jamming or shaking of the carrier plate 200 due to asynchrony.

[0044] During operation, the carrier plate 200 is placed on the three-track double-speed chain 140. After the drive motor 112 starts, it drives all the double-speed chains 140 to run synchronously through belt transmission and gear system. Rolling friction is formed between the rollers 141 of the double-speed chain 140 and the carrier plate 200 to reduce the impact of starting and stopping. The limit plates 122 and 132 and the guide wheel 150 together ensure the stability and directional accuracy of the carrier plate 200. The reinforcing rod 300 and the chain guide block 160 improve the rigidity and reliability of the device. Therefore, the structure of this utility model is reasonable and it is particularly suitable for the efficient and stable transmission of large carrier plates under heavy load in the photovoltaic industry.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
