DETAILED DESCRIPTION

[0031] With reference to the drawings and the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all the embodiments. Based on the embodiments of the present disclosure, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present disclosure.

Figure 2 Fig. 2 shows a schematic diagram of a conveying mechanism according to an embodiment of the present disclosure. Figure 3 Fig. 3 shows an exploded view of a base according to an embodiment of the present disclosure. Figure 4 Fig. 4 shows a schematic diagram of a conveying mechanism carrying a carrier according to an embodiment of the present disclosure. The direction indicated by arrow X is the first direction, and the direction indicated by arrow Y is the second direction. The first direction X and the second direction Y are perpendicular to each other and both lie in the horizontal plane. Subsequently, they will not be emphasized separately.

[0033] An embodiment of the present disclosure provides a conveying mechanism, such as Figure 1 The conveying mechanism 10 has at least one working position 101, and the conveying mechanism 10 is configured to convey the carrier 40 carrying the at least one sheet carrying assembly to the working position 101.

[0034] It can be understood that the carrier 40 is configured to carry the sheet carrying assembly. For example, the carrier 40 can be a carrier plate designed to be able to carry one or more sheet carrying assemblies in size. When the carrier plate is able to carry two or more sheet carrying assemblies, the plurality of sheet carrying assemblies can be placed on the carrier plate along the first direction X, and the plurality of sheet carrying assemblies can be connected together by detachable connection structures such as buckles, bolts, etc. Alternatively, the sheet carrying assembly can carry a plurality of sheets, including unprocessed sheets and processed sheets. The conveying mechanism 10 can be configured to convey the sheet carrying assembly carrying the sheets (which can be unprocessed sheets or processed sheets) to a working position 101.

[0035] Alternatively, the sheet can be a solar cell sheet, which needs to be processed through different processes to finally become a solar cell product that can be used. The solar cell sheet can be, for example, rectangular or circular in shape. The sheet can be made of, for example, silicon material as the main material of the substrate, or perovskite material as the main material of the substrate, without specific limitation.

[0036] It should be emphasized that the conveying mechanism 10 can also be configured to convey the sheet material carrying assembly without the sheet material to the working position 101. For the convenience of introducing the relevant structure of the conveying mechanism 10, the sheet material carried by the sheet material carrying assembly carried on the carrier 40 conveyed by the conveying mechanism 10 is taken as an example for introduction in the embodiments of the present disclosure. Subsequently, for the convenience of understanding, it is no longer emphasized whether the sheet material carrying assembly carried by the carrier 40 has a sheet material, and it is uniformly defaulted that the sheet material carrying assembly carries a sheet material, and for the convenience of description, the sheet material carrying assembly carrying the unprocessed sheet material is simply referred to as “unprocessed sheet material carrying assembly”, and the sheet material carrying assembly carrying the processed sheet material is simply referred to as “processed sheet material carrying assembly”, which will not be emphasized separately in the subsequent description.

[0037] Specifically, the conveying mechanism 10 is applied to the processing equipment 100, and the processing equipment 100 includes a process mechanism 20 configured to process the sheet material in at least one sheet material carrying assembly. The process mechanism 20 may, for example, include at least one of a diffusion furnace for diffusion process, an annealing furnace for annealing process, an oxidation furnace, a low pressure chemical vapor deposition (LPCVD) furnace and a plasma enhanced chemical vapor deposition (PECVD) furnace, which can be adaptively adjusted according to actual process processing requirements and is not specifically limited.

[0038] Optionally, the processing equipment 100 can also include an up-down material mechanism 30. The up-down material mechanism 30 can load the unprocessed sheet material carrying assembly onto the carrier 40 of the conveying mechanism 10, and the conveying mechanism 10 can convey the carrier 40 to the position of the corresponding process mechanism 20 to provide the unprocessed sheet material carrying assembly to the process mechanism 20. The processed sheet material carrying assembly processed by the process mechanism 20 can be placed on the carrier 40 of the conveying mechanism 10, and the conveying mechanism 10 can convey the processed sheet material carrying assembly to the position of the corresponding up-down material mechanism 30, and the up-down material mechanism 30 can unload the processed sheet material carrying assembly from the carrier 40 to other processes.

[0039] Optionally, the conveying mechanism 10 can be provided with at least one working position 101, the working position 101 being configured to carry the carrier 40. The working position 101 can be provided as one, which is arranged on the conveying mechanism 10 close to the feeding and discharging mechanism 30. Alternatively, the working position 101 can be provided as two, which are respectively arranged on the conveying mechanism 10 on both sides in the first direction X, wherein the working position 101 close to the process mechanism 20 is taken as the first working position 101a, and the working position 101 close to the feeding and discharging mechanism 30 is taken as the second working position 101b. When the carrier 40 is located at the second working position 101b, the feeding and discharging mechanism 30 can feed the unprocessed sheet carrying assembly to the carrier 40 at the second working position 101b, and after the conveying mechanism 10 conveys the carrier 40 at the second working position 101b to the first working position 101a, the unprocessed sheet carrying assembly on the carrier 40 can be carried into the process mechanism 20 for processing. Similarly, when the carrier 40 is located at the first working position 101a, the processed sheet carrying assembly after the process of the process mechanism 20 can be carried to the carrier 40 at the first working position 101a, and after the conveying mechanism 10 conveys the carrier 40 at the first working position 101a to the second working position 101b, the processed sheet carrying assembly on the carrier 40 is discharged to the next process by the feeding and discharging mechanism 30.

[0040] It can be understood that the number and specific position of the working position 101 provided by the conveying mechanism 10 can be selected according to the matching relationship and flow mode between the process mechanism 20, the conveying mechanism 10 and the feeding and discharging mechanism 30, and is not specifically limited. In order to facilitate understanding, the specific structure of the conveying mechanism 10 is described in the scheme of providing one working position 101, but is not limited thereto.

[0041] As shown in Figures 2 to 4 , the conveying mechanism 10 comprises a base 1, a conveying assembly 2, a sensing assembly 3, a buffer assembly 4 and a controller. The conveying assembly 2 is connected to the base 1 and is configured to drive the carrier 40 to move along the first direction X. The sensing assembly 3 is connected to at least one of the base 1 and the carrier 40. The controller is in communication connection with the conveying assembly 2 and the sensing assembly 3. When the conveying assembly 2 drives the carrier 40 to move towards the working position 101, the sensing assembly 3 is configured to generate a sensing signal when the distance between the carrier 40 and the working position 101 is sensed to be a preset distance, and the controller reduces the speed of the conveying assembly 2 driving the carrier 40 to move to a first speed according to the sensing signal. The buffer assembly 4 is connected to the base 1 and is arranged on one side of the working position 101. Before the carrier 40 moves to the working position 101 at the first speed, the buffer assembly 4 is configured to be able to abut against the carrier 40 and stop the carrier 40 at the working position 101 under the buffering action of the buffer assembly 4.

[0042] The transmission mechanism 10 provided by the embodiments of the present disclosure can detect the distance between the carrier 40 and the working position 101 in real time during the process of transmitting the carrier 40 to the working position 101 by the transmission assembly 2, and generate an induction signal when the distance between the two is reduced to a preset distance. The controller can reduce the moving speed of the carrier 40 transmitted by the transmission assembly 2 to a first speed according to the induction signal, and then make the carrier 40 move to the working position 101. The carrier 40 can be buffered by the buffer assembly 4 before the carrier 40 completely enters the working position 101, so that the carrier 40 can gradually slow down from the first speed to stop in the working position 101. Such a matching structure can make the carrier 40 be double-decelerated and limited by the induction assembly 3 and the buffer assembly 4 before moving to the working position 101, so that the carrier 40 can be stably and reliably stopped in the working position 101, avoiding the influence of the size, weight and quantity of the sheet material in the sheet material bearing assembly on the sheet material bearing assembly on the moving carrier plate under the influence of inertia, thereby avoiding the over-movement of the sheet material bearing assembly under the influence of inertia or the collision with other mechanisms, thereby meeting the demand that the large-size and large-weight sheet material bearing assembly can be stably and reliably transferred to the working position 101 by the transmission mechanism 10.

[0043] In addition, the double-deceleration and limiting mode by the induction assembly 3 and the buffer assembly 4 can make the transmission assembly 2 drive the carrier 40 to transmit the carrier 40 at a higher moving speed before the carrier 40 is decelerated to the first speed. From the whole transmission process of the transmission assembly, the efficiency of transmitting the carrier 40 to the working position 101 at a time can be obviously improved.

[0044] As Figure 3 The base 1 can specifically include a plurality of first profiles 11, a plurality of second profiles 12, a first sealing plate 13 and a second sealing plate 14. The plurality of first profiles 11 are arranged at intervals along the second direction Y, and each first profile 11 extends along the first direction X. The plurality of second profiles 12 are arranged at intervals along the first direction X, and each second profile 12 connects the plurality of first profiles 11. The first sealing plate 13 is connected with the first profile 11, and the second sealing plate 14 is connected with the first profile 11. The first profile 11, the second profile 12, the first sealing plate 13 and the second sealing plate 14 enclose at least one hollow accommodating cavity 15. It can be understood that the signal lines used for communication connection between the controller and the related electronic devices of the induction assembly 3 and the transmission assembly 2 can be arranged in the accommodating cavity 15 or in the profiles. Corresponding wiring holes or wiring channels can be arranged in the first profile 11, the second profile 12, the first sealing plate 13 and the second sealing plate 14 for the wiring of the signal lines.

[0045] Optionally, the conveying mechanism 10 can further be provided with a heat insulation cover 5, the heat insulation cover 5 and the base 1 are provided with a heat insulation cavity, the buffer assembly 4 and the sensing assembly 3 provided on the base 1 are arranged in the heat insulation cavity. Moreover, the heat insulation cover 5 is provided with an opening on the side facing the working position 101, at least the sensing end of the sensing assembly 3 and the part of the buffer assembly 4 in contact with the carrier 40 are exposed.

[0046] It can be understood that, in the case that the conveying mechanism 10 is provided with a first working position 101a and a second working position 101b at positions close to the two ends in the first direction X, the buffer assembly 4 and the sensing assembly 3 can be provided as two groups, i.e., the first working position 101a and the second working position 101b are respectively provided with the buffer assembly 4 and the sensing assembly 3, and no matter which working position 101 the carrier 40 moves to, the carrier 40 will be stopped by the deceleration and limiting of the buffer assembly 4 and the sensing assembly 3, and will not be described in detail.

[0047] Figure 5 The first working position 101a is shown. Figure 4 The partial enlarged view of the A area in the conveying mechanism is shown. Figure 6 The second working position 101b is shown. Figure 5 The partial enlarged view of the C area in the conveying mechanism is shown. Figure 7 The third working position 101c is shown. Figure 4 The partial enlarged view of the B area in the conveying mechanism is shown. Figure 8 The schematic view of the conveyor provided by an embodiment of the present disclosure cooperating with the supporting wheel and the anti-falling wheel is shown. Figure 9 The schematic view of the supporting wheel provided by an embodiment of the present disclosure is shown. Figure 10 The schematic view of the anti-falling wheel provided by an embodiment of the present disclosure is shown. Figure 11 The schematic view of the blocking edge assembly provided by an embodiment of the present disclosure is shown.

[0048] As Figures 4 to 6 The sensing assembly 3 includes a first sensing part 31 and a second sensing part 32, the first sensing part 31 is arranged on the base 1, and the first sensing part 31 is electrically connected with the controller; the second sensing part 32 is arranged on the side of the carrier 40 facing the first sensing part 31, and in the case that the conveying assembly 2 carries the carrier 40, the first sensing part 31 and the second sensing part 32 are oppositely arranged in the first direction X, the second sensing part 32 is electrically connected with the controller, and the first sensing part 31 and the second sensing part 32 are configured to generate an induction signal when the distance between them is a preset distance.

[0049] Specifically, in the case that the conveying assembly 2 carries the carrier 40, and before the carrier 40 moves to the working position 101, the first sensing member 31 and the second sensing member 32 are respectively located on two sides of the working position 101 in the first direction X. The first sensing member 31 arranged on the base 1 is configured to be fixed, and the first sensing member 31 can be arranged to be aligned or substantially aligned with the edge of the working position 101. The sensing assembly 3 mentioned above can detect the preset distance between the carrier 40 and the working position 101 in real time, which specifically refers to the first distance L1 between the first sensing member 31 and the second sensing member 32 minus the length of the working position 101 in the first direction X. In actual work, we can generate an induction signal based on the first distance L1 between the first sensing member 31 and the second sensing member 32 to control the carrier 40 to slow down to a first speed before moving to a position close to the working position 101, thereby providing the first buffering for stopping the carrier 40 at the working position 101.

[0050] It can be understood that the first speed and the first distance L1 can be obtained by comprehensively considering the actual weight, size, etc. of the sheet carrying assembly carried by the carrier 40 and the initial movement speed of the carrier 40 in the conveying assembly 2, etc. and can be adaptively adjusted according to actual needs, which is not specifically limited here.

[0051] In some embodiments, the buffering assembly 4 includes a fixed member 42, an elastic member, and a movable member 41. The fixed member 42 is connected to one side of the base 1, and the fixed member 42 is arranged on one side of the working position 101 in the first direction X. An accommodating cavity is arranged on one end of the fixed member 42 facing the working position 101, and the elastic member is arranged in the accommodating cavity. The movable member 41 is movably connected to the accommodating cavity, and the elastic member connects the fixed member 42 and the movable member 41. The movable member 41 has an abutting end. During the movement of the carrier 40 to the working position 101 at the first speed, the carrier 40 can abut against the abutting end and push the movable member 41 to move in the direction of the fixed member 42 in the first direction X. The elastic member is deformed under pressure to generate a rebound force, so that the carrier 40 stops at the working position 101.

[0052] It can be understood that the buffering assembly 4 can be arranged as an oil pressure buffer. The base of the oil pressure buffer serves as the fixed member 42, and the oil pressure rod serves as the movable member 41. The force of moving the oil pressure rod in the first direction X by internal oil pressure serves as the elastic member, thereby buffering the contacted carrier 40 and stopping the carrier 40. The buffering assembly 4 can also be arranged as other structures capable of realizing the contact buffering and stopping of the carrier 40 at the working position 101, which is not specifically limited.

[0053] Optionally, the fixing member 42 is arranged on the side of the working position 101 away from the carrier 40, and before the abutting end contacts the carrier 40, the abutting end is located in the working position 101 in the first direction X and has a certain distance from the edge of the working position 101, so that the carrier 40 can first abut against the abutting end before the carrier 40 completely enters the working position 101. The movement of the carrier 40 causes the elastic member to be compressed, thereby utilizing the elastic force of the elastic member to prevent the carrier 40 from continuing to move forward, and thereby stopping the carrier 40 in the working position 101.

[0054] It can be understood that the degree of deformation and the size of the elastic force of the elastic member under compression can be obtained by comprehensively calculating the overall weight of the carrier 40 carrying the sheet carrying assembly, the size of the first speed, and the like, and are not specifically limited here.

[0055] Optionally, a fixing frame 43 is connected to the base 1 at a position close to the working position 101, and the first sensing member 31 and the buffer assembly 4 can be detachably connected to the fixing frame 43.

[0056] In an optional embodiment, the conveying mechanism 10 further comprises a detection sensor 9 connected to the base 1, and the detection sensor 9 is arranged on the side close to the working position 101. The detection sensor 9 is electrically connected to the controller, and the detection sensor 9 is configured to detect whether the carrier 40 located in the working position 101 carries the sheet carrying assembly.

[0057] As Figure 7 and Figure 8 The conveying assembly 2 comprises a driving shaft 23, at least one driving wheel 24, at least one driven wheel 22, a conveying belt set, and a driving member 25. The driving shaft 23 is arranged on one side of the base 1 in the first direction X, and extends in the second direction Y perpendicular to the first direction X. The driving shaft 23 can drive the driving wheel 24 to rotate.
