Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a carrier plate conveying device based on roller conveying. Background Technology

[0002] With the development of photovoltaic module manufacturing technology, a technological trend has emerged towards high power and large size. This technology has the characteristics of improving module output power and power generation efficiency, which in turn leads to the demand for high-temperature resistant conveying mechanisms for transporting large-size and heavy photovoltaic panels in high-temperature processes.

[0003] In related technologies, conventional roller conveyors are typically used to transport the photovoltaic substrates. For example, rollers made of metal are installed inside a high-temperature furnace chamber, and the rollers are driven by a motor to rotate, thereby propelling the photovoltaic substrates placed on the rollers forward.

[0004] However, the above-mentioned roller conveyor or conveyor belt method has the following problems: First, for large-sized and heavy carrier plates, traditional rollers or conveyor belts are prone to thermal deformation in continuous high-temperature environments, resulting in unstable operation, causing the carrier plates to deviate, jam, or even fall off, which poses safety hazards. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a carrier plate conveying device based on roller conveying, which enables the carrier plate to be transported in a high-temperature environment and allows the conveying mechanism to operate for a long time in a high-temperature environment.

[0006] The technical solution adopted in this utility model is as follows: A plate conveying device based on roller conveying, comprising: Assembly plate; A transmission assembly is disposed on one side of the assembly plate; The transmission assembly includes a drive motor, an output pulley, and a transmission pulley. The output end of the drive motor is connected to the output pulley. The output pulley is engaged with the adjacent transmission pulleys on both sides via a belt. In the length direction, every two adjacent transmission pulleys are driven by a belt. Multiple roller assemblies are arranged above the assembly plate along the length direction of the assembly plate, and the two sides of each roller assembly are connected to the transmission pulley of the transmission assembly; Guide components are symmetrically arranged on both sides of the assembly plate in the width direction, and the spacing between the symmetrically arranged guide components matches the width of the carrier plate; Through-beam sensors are configured at the inlet and outlet ends of the assembly plate.

[0007] As a further improvement to the above technical solution: In one embodiment, a first tensioning pulley is provided between the output pulley and the adjacent drive pulleys on both sides; a second tensioning pulley is provided between every two drive pulleys.

[0008] In one embodiment, the roller assembly includes a rotating shaft, a bearing housing, and rollers; the rotating shaft is connected to the drive pulley, the bearing housing is mounted on the mounting plate and supports the rotating shaft, and multiple rollers are arranged along the width direction of the rotating shaft.

[0009] In one embodiment, the guide assembly includes a mounting base, a support shaft, and a guide wheel; the mounting base is disposed on the assembly plate, the support shaft is vertically disposed on the mounting base, and the guide wheel is mounted on the top of the support shaft via a bearing.

[0010] In one embodiment, the roller is made of polytetrafluoroethylene (PTFE).

[0011] In one embodiment, the bearing is a ceramic bearing.

[0012] In one embodiment, the guide wheel is made of polytetrafluoroethylene (PTFE).

[0013] In one embodiment, the number of through-beam sensors is two sets, which are fixed to the inlet and outlet ends of the assembly plate, respectively, for detecting the position of the carrier plate.

[0014] In one embodiment, the rollers on the single rotating shaft are evenly distributed along the axial direction of the rotating shaft.

[0015] In one embodiment, the mounting base of the guide component is detachably mounted on the assembly plate, and the spacing between the symmetrically arranged guide components is adjusted to match the width of the carrier plate.

[0016] The beneficial effects of this utility model are as follows: This utility model has a compact structure. By using multiple independent rollers arranged axially along the rotation axis to form a roller assembly, the frictional contact area is greatly reduced, thus lowering frictional resistance and driving power requirements. In addition, the transmission assembly uses a drive motor to drive the output pulley via a belt, and then the power is sequentially transmitted to multiple transmission pulleys via the belt. With the cooperation of the first tension pulley and the second tension pulley, the entire belt transmission system is always kept in a proper tension state, preventing the belt from loosening, slipping, or skipping teeth that may occur at high temperatures. This ensures the synchronicity and stability of power transmission, allowing the multiple roller assemblies to rotate in a coordinated manner.

[0017] This utility model also has the following advantages: The rollers and guide wheels of this invention are made of polytetrafluoroethylene, a high-temperature resistant material that can withstand the high-temperature environment in photovoltaic manufacturing processes. They are not prone to thermal deformation or performance degradation, thus ensuring the stability of the conveying mechanism during long-term operation at high temperatures and effectively avoiding safety hazards such as carrier plate deviation, jamming, or detachment caused by component deformation.

[0018] This utility model also features guide components symmetrically arranged on both sides of the assembly plate. The guide wheels rotate flexibly through the ceramic bearings at the top. The ceramic bearings themselves have the characteristics of high temperature resistance, wear resistance, and no need for lubrication, which perfectly adapts to the requirements of high temperature and clean production environment. The guide wheels and the side of the carrier plate form a rolling guide, which can not only accurately constrain the carrier plate and prevent it from deviating, but also avoid rigid scraping with the side of the carrier plate, further ensuring the stability of the conveying and the integrity rate of the product.

[0019] This invention features through-beam sensors at the inlet and outlet ends of the assembly plate, which can detect the position and departure status of the carrier plate. This signal can be used in conjunction with PLC to control the start and stop of the drive motor, thereby achieving automated conveying. It can also help the system determine the real-time position of the carrier plate within the conveying device, providing information for the process control of the entire production line and improving the level of intelligence.

[0029] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0030] like Figures 1-3 The accompanying drawing shows a schematic diagram of the structure of a plate conveying device based on roller conveying 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 roller transmission, including an assembly plate 100, a transmission component 200, multiple roller assemblies 300, a guide component 400, and a through-beam sensor 500.

[0032] In some embodiments, the assembly plate 100 is typically made of sheet metal with sufficient rigidity and high temperature resistance to fix and support other components, and its size and shape can be designed according to actual transport requirements; A transmission assembly 200 is provided on one side of the assembly plate 100 along its length. The transmission assembly 200 is used to provide power and transmit it to the roller assembly 300.

[0033] Furthermore, the transmission assembly 200 includes a drive motor 210, an output pulley 220, a transmission pulley 230, a first tension pulley 240, and a second tension pulley 250; The drive motor 210 is fixedly mounted on the assembly plate 100, and its output end is connected to the output pulley 220. The output pulley 220 cooperates with the adjacent transmission pulleys 230 on both sides through a belt to form a belt drive system; Along the length direction, power is also transmitted sequentially to multiple drive pulleys 230 via belt drive between every two adjacent drive pulleys 230. To ensure the stability and reliability of the belt drive, a first tensioning pulley 240 is provided between the output pulley 220 and the adjacent transmission pulleys 230 on both sides, for adjusting and maintaining the belt tension. Meanwhile, a second tensioner 250 is provided between every two transmission pulleys 230 to further prevent the belt from becoming loose, slipping, or skipping teeth in high-temperature environments, ensuring the synchronization and stability of power transmission, and enabling multiple roller assemblies 300 to rotate in a coordinated manner.

[0034] Furthermore, the roller assembly 300 is disposed above the assembly plate 100 along the length direction of the assembly plate 100, for directly bearing and conveying the carrier plate; Both sides of each roller assembly 300 are connected to the drive pulley 230 of the transmission assembly 200 to receive power; The roller assembly 300 includes a rotating shaft 310, a bearing housing 320, and a roller 330; The rotating shaft 310 is connected to the transmission pulley 230. When the transmission pulley 230 rotates, it drives the rotating shaft 310 to rotate synchronously. The bearing housing 320 is mounted on the assembly plate 100 to support the rotating shaft 310 and ensure its smooth rotation. Multiple rollers 330 are arranged on the rotating shaft 310 along its width.

[0035] Understandably, the roller 330 is preferably made of polytetrafluoroethylene (PTFE), which has high temperature resistance and self-lubricating properties. It can work for a long time in high temperature environments without easily deforming, while reducing friction with the bottom surface of the carrier plate and preventing scratches.

[0036] In one embodiment, the rollers 330 are evenly distributed along the axial direction of the rotation shaft 310 to provide uniform support and stable conveying.

[0037] Furthermore, the guide components 400 are symmetrically arranged on both sides of the assembly plate 100 in the width direction to constrain the running trajectory of the carrier plate and prevent it from deviating. The spacing between the symmetrically arranged guide components 400 matches the width of the carrier plate, ensuring that the carrier plate remains centered during transport; The guide assembly 400 includes a mounting base 410, a support shaft 420, and a guide wheel 430; The mounting base 410 is disposed on the assembly plate 100 and is preferably fixed by a detachable method (e.g., bolt connection) so as to adjust the spacing between the two guide components 400 to accommodate carrier plates of different widths. The support shaft 420 is vertically mounted on the mounting base 410, and the guide wheel 430 is mounted on the top of the support shaft 420 via a bearing; It is understandable that ceramic bearings are preferred because they are resistant to high temperatures, wear-resistant, and require no lubrication, making them suitable for high-temperature and clean environments. Understandably, the guide wheel 430 is preferably made of polytetrafluoroethylene material, which forms rolling contact with the side of the carrier plate, so as to provide precise guidance and avoid rigid scratches.

[0038] In some embodiments, the through-beam sensor 500 is configured at the inlet and outlet ends of the assembly plate 100 for detecting the position of the carrier plate; Specifically, there are two sets of through-beam sensors 500, which are fixed at the inlet and outlet ends respectively.

[0039] When the through-beam sensor 500 at the inlet end detects the entry of the carrier plate, it can trigger the drive motor 210 to start, which drives the roller assembly 300 to rotate through belt transmission, and begins to transport the carrier plate. When the through-beam sensor 500 at the outlet end senses that the carrier plate has left, or when the through-beam sensors 500 at both ends fail to sense the carrier plate at the same time, the system can determine that the carrier plate is inside the conveying device and control the operation of the drive motor 210 accordingly to achieve automated conveying.

[0040] In practical applications, the working process of this application is as follows: During operation, the carrier plate is placed on the rollers 330 of the roller assembly 300. The drive motor 210 drives the transmission pulley 230 through the output pulley 220 and the belt, thereby driving the rotating shaft 310 and the rollers 330 to rotate, pushing the carrier plate forward in a point contact manner; Meanwhile, the guide wheel 430 of the guide assembly 400 makes rolling contact with the side of the carrier plate to prevent the carrier plate from deviating.

[0041] The through-beam sensor 500 is used to monitor the position of the carrier board and works with the control system (such as PLC) to achieve precise start-stop and status monitoring.

[0042] 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.

[0043] 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.
