[0003] In related technologies, for heavy-load transmission of such large carrier plates, roller conveyors consisting of multiple sets of rollers arranged in parallel are usually used.

[0004] However, the roller conveying method described above is prone to roller surface deflection, drive slippage, or asynchronous start and stop when facing large-load photovoltaic panels, which can cause the panels to deviate or vibrate. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a carrier plate conveying and positioning device based on belt conveyor, which can be used for conveying large carrier plates in the photovoltaic industry and can avoid deviation and achieve positioning.

[0006] The technical solution adopted in this utility model is as follows: A belt conveyor-based plate conveying and positioning device includes: A conveying assembly, comprising a first conveying track, a second conveying track, and a third conveying track arranged in parallel 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 all equipped with toothed belts, the top surface of which is used to abut against the bottom of the carrier plate to achieve conveying in the length direction; A forward thrust assembly is provided on the inlet side of the conveying assembly along the length direction; A positioning sensor is provided on the side of the conveying assembly furthest from the inlet in the longitudinal direction; A side pusher is provided on one side of the conveying assembly in the width direction, and a baffle is provided on the other side of the conveying assembly, with the side pusher being positioned directly opposite the baffle; A through-beam sensor is also provided on the inlet side of the conveying assembly along the length direction to detect whether the carrier plate enters the conveying assembly; A photoelectric sensor is provided below the conveying assembly. The photoelectric sensor is arranged along the height direction and is closer to the positioning sensor in the length direction than the forward push assembly.

[0007] As a further improvement to the above technical solution: In one embodiment, the conveying assembly further includes a drive mechanism, which includes a drive motor, a drive wheel, a transmission belt, a transmission wheel, and a transmission shaft. The output end of the drive motor is connected to the drive wheel, the drive wheel engages with the transmission wheel via the transmission belt, and the transmission wheel is fixed on the transmission shaft and coaxially arranged with the transmission shaft. The first conveying track has a first pulley on one side of its length direction, the first pulley is located on the transmission shaft and rotates synchronously with the transmission shaft, and a second pulley is provided on the other side of the first conveying track in its length direction. The toothed belt is arranged around the first pulley and the second pulley.

[0008] In one embodiment, the second conveying track has a third pulley on one side of its length direction, the third pulley being located on the drive shaft and rotating synchronously with the drive shaft, and a fourth pulley on the other side of the second conveying track in the length direction, the toothed belt being arranged around the third pulley and the fourth pulley.

[0009] In one embodiment, the third conveying track has a fifth pulley on one side of its length direction, the fifth pulley is located on the drive shaft and rotates synchronously with the drive shaft, and the third conveying track has a sixth pulley on the other side of its length direction, and the toothed belt is arranged around the fifth pulley and the sixth pulley.

[0010] In one embodiment, the forward thrust assembly includes a first cylinder, a guide rod, a connecting plate, a mounting plate, and a second cylinder; the first cylinder is arranged along the length direction, and the first cylinder output head of the first cylinder extends and retracts in the length direction; the end of the first cylinder output head is connected to the connecting plate; the mounting plate is provided on the connecting plate; the second cylinder is disposed on the mounting plate; and the second cylinder output head of the second cylinder extends and retracts in the height direction.

[0011] In one embodiment, the guide rod is disposed on both sides of the output head of the first cylinder, one side of the guide rod is connected to the cylinder seat of the first cylinder, and the other side is connected to the connecting plate.

[0012] In one embodiment, the side-push assembly includes a side-push cylinder and a side-push plate. The side-push cylinder is arranged along the width direction, and the output end of the side-push cylinder is connected to the side-push plate, with the output end of the side-push cylinder facing the baffle.

[0013] In one embodiment, the through-beam sensor, the position sensor, and the photoelectric sensor are all connected to the control system via signal lines.

[0015] The beneficial effects of this utility model are as follows: This invention features a compact structure. By employing three parallel conveyor tracks, one of which is positioned at the central core load-bearing location, a stable support structure is formed. This effectively distributes the pressure of large-sized, heavy-duty load plates, fundamentally avoiding the roller surface sagging problem caused by excessive load in traditional roller conveyors. Furthermore, a toothed belt is used as the transmission medium, and all pulleys on the tracks are synchronously driven by a common drive shaft, ensuring absolute synchronization of all conveying points at the power source. This mechanical rigid synchronization eliminates load plate deviation, twisting, or vibration caused by starting, stopping, or speed differences among multiple drive sources, resulting in a smoother and more reliable conveying process.

[0016] This utility model also has the following advantages: This utility model integrates a positioning mechanism with two dimensions: side push and front push. The side push component cooperates with a fixed baffle to calibrate the carrier plate to the reference position in the width direction; the front push component, through the action of "extending-lifting-retracting", accurately pushes the carrier plate to the target position in the length direction, thereby achieving precise positioning of the carrier plate in the plane. This invention, by setting up a through-beam sensor, a position sensor, and a photoelectric sensor, and clarifying their cooperative sequence in the process, can sense the entry of the carrier plate, its position on the conveyor line, and the timing of triggering the positioning action, thereby automating the conveying and positioning process, reducing manual intervention, and improving positioning accuracy and efficiency.

[0028] 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.

[0029] like Figures 1-5 The accompanying drawing shows a schematic diagram of the structural state of a carrier plate conveying and positioning device based on belt conveyor in one embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0030] This application provides a carrier plate conveying and positioning device based on belt conveyor, including a conveying component 200, a forward pushing component 300, a side pushing component 400, a baffle 500 and multiple sensors, which together realize the automatic conveying and precise positioning of the carrier plate 100.

[0031] In some embodiments, the conveying assembly 200 includes a first conveying track 210, a second conveying track 220, and a third conveying track 230 arranged in parallel along the width of the device. The first conveying track 210 is located between the second and third conveying tracks 220 and 230, forming a stable support plane, particularly suitable for supporting large-sized, heavy carrier plates 100, such as photovoltaic carrier plates. A toothed belt 240 is wound around each of the three conveying tracks. The top surface of the toothed belt 240 is used to directly contact the bottom of the carrier plate 100, driving the carrier plate 100 to move along its length through friction. The power for the conveying assembly 200 comes from a centralized drive mechanism, including a drive motor 211. After the drive motor 211 starts, its output drives the drive wheel 212 to rotate. The drive wheel 212 transmits power to the transmission wheel 214 via a transmission belt 213 (such as a synchronous belt). The transmission wheel 214 is fixedly mounted on a transversely arranged transmission shaft 215 and is coaxial with the transmission shaft 215, thereby driving the transmission shaft 215 to rotate synchronously.

[0032] Specifically, for each conveyor track: The first conveying track 210 has a first pulley 216 on one side of its length (i.e., the side where the drive shaft 215 is located). The first pulley 216 is fixedly mounted on the drive shaft 215 and can rotate synchronously with the drive shaft 215. A second pulley 217 is provided on the other side of the track. A toothed belt 240 is wrapped around the first pulley 216 and the second pulley 217.

[0033] Similarly, the second conveying track 220 has a third pulley 221 on one side of the drive shaft 215 and a fourth pulley 222 on the other side, with a toothed belt 240 wrapped around the third pulley 221 and the fourth pulley 222.

[0034] The third conveying track 230 has a fifth pulley 231 on one side of the drive shaft 215 and a sixth pulley 232 on the other side. A toothed belt 240 is wrapped around the fifth pulley 231 and the sixth pulley 232. This design ensures that the drive pulleys of all toothed belts 240 are driven by the same drive shaft 215, achieving absolute synchronization of the movement of the three tracks and effectively preventing the carrier plate 100 from deviating.

[0035] In some embodiments, a through-beam sensor 600 is installed on the inlet side of the conveying assembly 200 along its length to detect whether the carrier plate 100 has entered the area of ​​the conveying device.

[0036] In some embodiments, the forward thrust assembly 300 is disposed on the inlet side of the conveying assembly 200 along its length direction, and is used for final positioning of the carrier plate 100 along its length direction. It mainly consists of a first cylinder 310, a guide rod 330, a connecting plate 340, a mounting plate 350, and a second cylinder 360. The first cylinder 310 is fixedly installed along the length direction of the device, and its first cylinder output head 320 can extend and retract along the length direction. A connecting plate 340 is fixedly connected to the end of the first cylinder output head 320. To ensure the stability of the extension and retraction movement of the first cylinder output head 320, guide rods 330 are also provided on both sides of it. One end of the guide rod 330 is connected to the cylinder seat of the first cylinder 310, and the other end is connected to the connecting plate 340. A mounting plate 350 is fixed on the connecting plate 340, and a second cylinder 360 is mounted on the mounting plate 350. The second cylinder 360 is disposed along the height direction, and its second cylinder output head 370 can extend upward or retract downward.

[0037] In some embodiments, a side-push assembly 400 is provided on one side of the conveying assembly 200 in the width direction, and a baffle 500 is fixedly installed on the other side, with the side-push assembly 400 positioned directly opposite the baffle 500. The side-push assembly 400 includes a side-push cylinder 410 and a side-push plate 420 fixed to its output end. The side-push cylinder 410 is arranged along the width direction, and when it is in operation, it can drive the side-push plate 420 to extend or retract horizontally towards the baffle 500.

[0038] In some embodiments, a positioning sensor 700 is provided at the other end of the conveying assembly 200 away from the inlet side (i.e. near the outlet end) in the length direction, for sensing whether the carrier plate 100 has reached the expected end position.

[0039] In some embodiments, a photoelectric sensor 800 is also disposed below the conveying assembly 200. The photoelectric sensor 800 is arranged along the height direction with its detection direction vertically upward, for detecting a specific position of the carrier plate 100 from the bottom. In the length direction, the photoelectric sensor 800 is positioned closer to the positioning sensor 700 than the forward push assembly 300.

[0040] The workflow of this utility model is as follows: In the initial state, the drive motor 211 operates, continuously providing conveying power through the toothed belt 240. When the carrier plate 100 is delivered to the device inlet, the through-beam sensor 600 first detects the entry of the carrier plate 100, and the system records this signal. The carrier plate 100 continues to be conveyed into the device under the drive of the toothed belt 240 until the through-beam sensor 600 detects that the carrier plate 100 has completely passed through (i.e., the signal changes from present to absent).

[0041] At this point, most of the carrier plate 100 has entered the device, and its front end is close to the positioning sensor 700 but has not yet been triggered. The photoelectric sensor 800, located below the conveying assembly 200, detects the bottom of the carrier plate 100 and sends a signal.

[0042] The location process then starts: Width direction positioning: The side push cylinder 410 of the side push assembly 400 is activated, pushing the side push plate 420 to extend horizontally, pushing the carrier plate 100 along the width direction, so that its other side is close to the opposite baffle 500, thus completing the width direction calibration.

[0043] Length Direction Positioning: The forward push assembly 300 begins operation. First, the first cylinder 310 drives the first cylinder output head 320 to extend towards the carrier plate 100, moving the connecting plate 340, mounting plate 350, and the second cylinder 360 forward together. Then, the second cylinder 360 actuates, driving the second cylinder output head 370 to extend upwards, so that its top end is higher than the conveying plane of the toothed belt 240 and contacts the bottom surface of the end of the carrier plate 100. Next, the first cylinder 310 reverses its action, pulling the first cylinder output head 320 back, thereby pulling the carrier plate 100 back a distance towards the inlet via the raised second cylinder output head 370, until the carrier plate 100 triggers the positioning sensor 700. At this point, the carrier plate 100 has also reached the preset position in the length direction.

[0044] After positioning is completed, the second cylinder 360 retracts, and both the forward thrust assembly 300 and the side thrust assembly 400 are reset, waiting for the next working cycle.

[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.
