Description

Technical Field

[0001] This invention belongs to the field of photovoltaic module production equipment, and particularly relates to a flexible alignment device and a positioning conveyor line. Background Technology

[0002] Photovoltaic modules are the core component of a solar power generation system. During the manufacturing process, photovoltaic modules need to be positioned to ensure that the next process can be processed accurately.

[0003] In existing technology, a centering roller is installed along the conveyor belt's conveying direction. Initially, the centering roller is positioned below the conveyor belt to avoid obstructing the photovoltaic modules being conveyed. After the photovoltaic modules reach their designated positions, the centering roller is pushed upwards by a cylinder until it is above the conveyor belt. The centering roller then approaches and pushes the photovoltaic modules. During the process from the point of contact with the photovoltaic modules until the modules are properly aligned, the centering roller impacts the photovoltaic modules, resulting in a high breakage rate. Summary of the Invention

The sliding direction of the movable plate is consistent with the alignment direction. The transverse guide rod passes through the transverse guide hole of the first substrate. The transverse guide rod can move along its length direction, and the length direction of the transverse guide rod is consistent with the correction direction. The second elastic element is sleeved on the transverse guide rod. One end of the second elastic element abuts against the end of the transverse guide rod, and the other end of the second elastic element abuts against the side plate of the first substrate. The elastic force of the second elastic element drives the transverse guide rod to be elastically pressed onto the moving plate.

[0010] Furthermore, the flexible alignment device also includes a second guide rail, a second slider, and a connecting plate. The second guide rail is fixed on the frame, and the guiding direction of the second guide rail is consistent with the alignment direction. The second slider slides in conjunction with the second guide rail; the middle part of the connecting plate is connected to the second slider, and one end of the connecting plate is connected to the moving plate.

[0011] Furthermore, the flexible alignment device also includes a first drive wheel, a first transmission belt, and a first motor. The first drive wheel is rotatably mounted on the frame, and the wheel axle axis of the first drive wheel is perpendicular to the sliding direction of the connecting plate. The first transmission belt is wound around the two first drive wheels; the first motor is connected to the first drive wheels; the other end of the connecting plate is connected to the upper belt body of the first transmission belt.

Detailed Implementation

[0016] The following is combined Figures 1 to 10 The present invention will now be described.

[0017] A flexible alignment device includes a conveyor belt 71 and a flexible alignment mechanism. The conveyor belt 71 is capable of conveying materials along the conveying direction. The materials can be photovoltaic modules a, plates, blocks, etc. The present invention does not limit these. The following description uses photovoltaic modules a as an example.

[0018] The flexible alignment mechanism includes a first substrate 11, which is located on one side of the conveyor belt 71 and has a transverse guide hole; a first alignment wheel 13 is located above the first substrate 11; and the upper end of a first lifting rod 12 is connected to the first alignment wheel 13, and the first lifting rod 12 can reciprocate in a direction perpendicular to the conveyor belt 71. The movable plate 16 is located below the first substrate 11. The movable plate 16 is slidably engaged with the first substrate 11. The sliding direction of the movable plate 16 is consistent with the alignment direction. The transverse guide rod 17 passes through the transverse guide hole of the first substrate 11. The transverse guide rod 17 can move along its rod length direction. The rod length direction of the transverse guide rod 17 is consistent with the correction direction. Specifically, the first substrate 11 includes a plate body 111 and a side plate 112. The side plate 112 has a transverse guide hole. The second elastic element 18 is sleeved on the transverse guide rod 17. One end of the second elastic element 18 abuts against the end of the transverse guide rod 17, and the other end of the second elastic element 18 abuts against the side plate of the first substrate 11. The elastic force of the second elastic element 18 drives the transverse guide rod 17 to be elastically pressed onto the moving plate 16.

[0019] The flexible alignment device also includes a first elastic element 14, which is located on the other side of the first substrate 11. The first elastic element 14 is sleeved on the first lifting rod 12. One end of the first elastic element 14 abuts against the back of the first substrate 11, and the other end of the first elastic element 14 abuts against the lower end of the first lifting rod 12. When the lower end of the first lifting rod 12 is pressed, the first elastic element 14 is compressed, and the first alignment wheel 13 can rise from the low position to the high position.

[0020] Furthermore, the flexible alignment device also includes a frame and a first limiting plate 30. The first limiting plate 30 is connected to the frame and is located below the first lifting rod 12. The first limiting plate 30 includes an upper plate 31 and a lower plate 33 arranged sequentially along the alignment direction. The surface of the upper plate 31 is higher than that of the lower plate 33. The upper plate 31 and the lower plate 33 are connected by an intermediate plate 32.

[0021] like Figure 2 and Figure 3 The first aligning wheel 13 is in the initial position. The elastic force of the first elastic element 14 drives the lower end of the first lifting rod 12 to press against the surface of the first limiting plate 30. The first lifting rod 12 can reciprocate between the upper plate 31 and the lower plate 33.

[0022] The first lifting rod 12 and the first centering wheel 13 move along the M1 direction. During the process of the first lifting rod 12 sliding from the lower plate 33 through the middle plate 32 to the upper plate 31, the first lifting rod 12 and the first centering wheel 13 rise along the M2 direction, that is, the first centering wheel 13 moves from a low position to a high position. Figure 4 and Figure 5 As shown, the first alignment wheel 13 is in the alignment position. By setting the first limit plate 30, the position change of the first alignment wheel 13 can be realized simply and efficiently without the need for pneumatic components such as cylinders. The overall cost of the alignment assembly is low and the reliability is high.

[0023] The first correction wheel 13 pushes the photovoltaic module a to complete the correction, as follows: Figure 6 and Figure 7 As shown, the positions of the first alignment wheel 13, the first substrate 11, and the first lifting rod 12 remain unchanged, while the moving plate 16 and the transverse guide rod 17 continue to move along the M1 direction. The second elastic element 18 is compressed, and the second elastic element 18 absorbs the impact energy generated by the collision between the first alignment wheel 13 and the photovoltaic module, preventing the first alignment wheel 13 from impacting the photovoltaic module a and damaging the cells of the photovoltaic module a, thereby reducing the damage rate of the photovoltaic module a during the alignment process.

[0024] The flexible alignment device also includes a ball bearing 15, which is disposed at the lower end of the first lifting rod 12. The ball bearing 15 protrudes from the lower end face of the first lifting rod 12, allowing the lower end of the first lifting rod 12 to roll on other components, thereby reducing wear on the lower end of the first lifting rod 12 and improving the service life and operational stability of the flexible alignment component.

[0025] Specifically, the flexible alignment device also includes a first guide rail 191, a first slider 192 and a moving plate 16. The two first guide rails 191 are fixed to the back of the first substrate 11, and the guiding direction of the first guide rails 191 is consistent with the alignment direction. Two first sliders 192 are slidably engaged with the first guide rail 191; a movable plate 16 is fixed on the first sliders 192, and the movable plate 16 has clearance holes through which the first lifting rod 12 passes. During the movement of the movable plate 16 along the M1 direction, interference between the first lifting rod 12 and the movable plate 16 can be avoided.

[0026] Specifically, the flexible alignment device also includes a second guide rail 21, a second slider 22 and a connecting plate 24. The second guide rail 21 is fixed on the frame, and the guiding direction of the second guide rail 21 is consistent with the alignment direction. The second slider 22 is slidably engaged with the second guide rail 21; the middle part of the connecting plate 24 is connected to the second slider 22, and one end of the connecting plate 24 is connected to the movable plate 16.

[0027] Furthermore, the flexible correction device also includes a first drive wheel 23, a first transmission belt 25 and a first motor 26. The first drive wheel 23 is rotatably mounted on the frame, and the wheel axle axis of the first drive wheel is perpendicular to the sliding direction of the connecting plate 24. The first transmission belt 25 is wound around the two first drive wheels 23; the first motor 26 is connected to the first drive wheels 23; the other end of the connecting plate 24 is connected to the upper belt body of the first transmission belt 25.

[0028] like Figure 2 As shown, the flexible alignment device also includes a second base plate 41, a second lifting rod 42, a second alignment wheel 43, and a second limiting plate 50. The second base plate 41 is located on the other side of the conveyor belt 71. The second base plate 41 is connected to the lower belt body of the first transmission belt 25. The second base plate 41 has a vertical guide hole. The second aligning wheel 43 is located above the second base plate 41; the second limiting plate 50 is connected to the frame and is located below the second lifting rod 42. The second limiting plate 50 has the same structure as the first limiting plate 30. The second lifting rod 42 passes through the vertical guide hole of the second substrate 41. The second lifting rod 42 can move along the guide direction of the vertical guide hole. A first elastic member 14 is sleeved on the second lifting rod 42. One end of the first elastic member 14 on the second lifting rod 42 abuts against the back of the second substrate 41, and the other end of the first elastic member 14 on the second lifting rod 42 abuts against the lower end of the second lifting rod 42. The elastic force of the first elastic member 14 drives the lower end of the second lifting rod 42 to press against the surface of the second limiting plate 50.

[0029] The upper belt of the first transmission belt 25 is connected to the first aligning wheel 13 through the connecting plate 24, and the lower belt of the first transmission belt 25 is connected to the second aligning wheel 43 through the second base plate 41. The first transmission belt 25 drives the first aligning wheel 13 and the second aligning wheel 43 to move closer or further apart from each other.

[0030] like Figure 8 As shown, the aforementioned flexible correction components can be two in parallel, with the two flexible correction mechanisms driven by a synchronous driver connected to the first motor 26.

[0031] like Figure 9 and Figure 10As shown, the flexible alignment device also includes a second drive wheel 61, a second transmission belt 62, a third alignment wheel 63, a fourth alignment wheel 64, and a second motor 65.

The third alignment wheel 63 and the fourth alignment wheel 64 are located above the conveyor belt 71 and are respectively connected to the upper and lower belt bodies of the second transmission belt 62. The second motor 65 is connected to the second drive wheel 61 and can drive the second transmission belt 62 to rotate so that the third alignment wheel 63 and the fourth alignment wheel 64 move closer to or further away from each other.
