Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to a novel automated carrier board mounting device. Background Technology

[0002] The HJT battery production process comprises four steps: texturing and cleaning → silicon-based thin film deposition (PECVD) → transparent conductive thin film deposition (PVD) → screen printing. Among these, PVD primarily involves depositing TCO thin films on both sides using magnetron sputtering. The basic principle of this method is as follows: the target material acts as the cathode, and the substrate acts as the anode. Under the influence of electric and magnetic fields, accelerated high-energy Ar ions bombard the target material. After energy exchange, atoms on the target surface escape from the original crystal lattice, and the sputtered particles deposit onto the substrate surface, reacting with oxygen atoms to form an oxide thin film.

[0003] The carrier plate serves as the anode, and the silicon wafers are fed into the PVD equipment via an automated loading machine for thin film deposition. When loading the carrier plate, it is handled by a carrier plate trolley.

[0004] However, the currently used pallet trolley is quite tall and cannot be automatically raised or lowered. The pallets must be manually lifted onto the trolley before being loaded and unloaded from the machine. Due to the weight of the pallets, four people are needed to move them, which is time-consuming and labor-intensive. In addition, a layer of ITO dust adheres to the pallets, which cannot be expelled if inhaled, posing a great hazard to the operators. Utility Model Content

[0041] The HJT battery production process comprises four steps: texturing and cleaning → silicon-based thin film deposition (PECVD) → transparent conductive thin film deposition (PVD) → screen printing. Among these, PVD primarily involves depositing TCO thin films on both sides using magnetron sputtering. The basic principle of this method is as follows: the target material acts as the cathode, and the substrate acts as the anode. Under the influence of electric and magnetic fields, accelerated high-energy Ar ions bombard the target material. After energy exchange, atoms on the target surface escape from the original crystal lattice, and the sputtered particles deposit onto the substrate surface, reacting with oxygen atoms to form an oxide thin film.

[0042] The carrier plate serves as the anode, and the silicon wafers are fed into the PVD equipment via an automated loading machine for thin film deposition. When loading the carrier plate, it is handled by a carrier plate trolley.

[0043] However, the current pallet trolley is quite tall and cannot be automatically raised or lowered. The pallets must be manually lifted onto the trolley before being loaded and unloaded. During loading and unloading, four operators lift the pallets from each of the four sides to the top of the trolley, where they are then transferred to the automated machine. Because the pallets are heavy, four people are required to move them, which is time-consuming and labor-intensive. Furthermore, the pallets are covered with a layer of ITO dust, which, if inhaled, cannot be expelled and poses a significant hazard to the operators.

[0044] To address the problem of manually lifting carrier plates onto the carrier cart during loading, which is time-consuming, labor-intensive, and poses a significant hazard to operators, this invention provides a novel automated carrier plate loading device. This device is a height-adjustable tool used for loading, unloading, and transporting carrier plates, offering ease of use. This invention utilizes a lifting mechanism to raise and lower the carrier plate, replacing manual handling. This reduces labor costs, and allows operators to control the lifting and lowering of the carrier plate from a distance, minimizing the possibility of operators inhaling ITO dust adhering to the carrier plate.

[0045] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0046] refer to Figure 1 This embodiment provides a novel automated carrier board mounting device, which is applied to the HJT battery production process.

[0047] refer to Figures 1 to 6 The novel automated carrier loading device of this embodiment includes a frame 1, a lifting platform 2, and a lifting mechanism. The lifting platform 2 is located above the frame 1 and is used to support and transport the carrier. The lifting mechanism is disposed between the frame 1 and the lifting platform 2 and is used to lift the carrier. The lifting mechanism has a first lifting position and a second lifting position. When the lifting mechanism is in the first lifting position, the lifting platform 2 is adapted to correspond to the position of the automated machine tool. When the lifting mechanism is in the second lifting position, the lifting platform 2 is adapted to correspond to the position of the carrier box.

[0048] It should be noted that the automated machine is a device that automatically pushes the carrier board into the PVD equipment, while the carrier board box is a device that stores the carrier board to be processed and the processed carrier board. The carrier board box has a certain height.

[0049] The aforementioned novel automated carrier loading device controls the height of the lifting platform 2 via a lifting mechanism, thereby controlling the lifting and lowering of the carrier. When loading, the carrier can be directly lifted by the lifting mechanism. Once the carrier reaches the automated loading station, it can be easily pushed into the PVD equipment. When unloading, the carrier moves from inside the PVD equipment to the lifting platform 2, and can be directly lowered by the lifting mechanism before being pushed into the carrier box. This embodiment eliminates the need for manual handling of the carrier to the carrier cart and then inputting it into the PVD equipment. Furthermore, unloading the carrier also requires no manual handling; the lifting mechanism controls the process, saving significant manpower and time.

[0050] In some embodiments, the lifting mechanism is a pneumatic lifting mechanism or an electric lifting mechanism.

[0051] Taking a pneumatic lifting mechanism as an example, the lifting mechanism includes positioning brackets 3 and cylinders 4. At least one pair of positioning brackets 3 are provided, with each pair arranged diagonally on the frame 1 or symmetrically in the middle of the frame 1. In this embodiment, one or more pairs of positioning brackets 3 can be provided, preferably two pairs. When two pairs of positioning brackets 3 are provided, the four positioning brackets 3 are respectively arranged at the four corners of the frame 1. At least one pair of cylinders 4 are provided, with the number of cylinders 4 corresponding to the number of positioning brackets 3. Each cylinder 4 includes a cylinder body 41, a cylinder piston 44, a cylinder fixed end, a cylinder inlet 42, and a cylinder exhaust 43. The cylinder fixed end is mounted on the positioning bracket 3, and the cylinder piston 44 is connected to the lifting platform 2.

[0052] Preferably, four cylinders 4 are distributed below the lifting platform 2. Compressed air enters the cylinders 4 through the cylinder inlet. The compressed air generates pressure inside the cylinders, causing the cylinder pistons to rise. The working surfaces apply pressure to the lifting platform, thereby causing the platform to rise. The maximum extension stroke of the cylinders is 80cm. Figure 5 As shown.

[0053] The lifting mechanism also includes a cylinder control assembly, which controls the movement of cylinder 4. The cylinder control assembly includes a valve island 5 and a pedal 6. The valve island mainly connects the pedal and the cylinder, serving the function of gas transmission and control. (Refer to...) Figure 4 The valve island 5 is provided with a first air inlet 51, a second air inlet 52, a first air outlet 53, and a second air outlet 54. The first air inlet 51 is connected to the cylinder air inlet 42, and the first air outlet 53 is connected to the cylinder exhaust outlet 43, thereby controlling the intake and exhaust of gas into and out of the cylinder, respectively. (Refer to...) Figure 6 The pedal 6 is a device that converts human breath energy into pneumatic energy. The pedal 6 is designed to allow the operator to control the cylinder by stepping on it. The pedal 6 is equipped with a pedal air inlet 61, a pedal exhaust port 62, a third air inlet 63, and a third air outlet 64. The pedal air inlet 61 and the pedal exhaust port 62 are connected to the outside atmosphere. The third air inlet 63 is connected to the second air inlet 52, and the third air outlet 64 is connected to the second air outlet 54.

[0054] In this embodiment, taking a configuration of four cylinders as an example, when the pedal is continuously pressed manually, air enters the pedal air inlet 61 and then the valve island. The four air inlets of the valve island connect to the four cylinders. Compressed air generates pressure inside the cylinders, causing the cylinder piston to rise. The cylinder working surface applies pressure to the lifting platform, causing the lifting platform to rise. When the pedal 6 is pressed down for an extended period, the gas in the cylinder is discharged from the pedal exhaust port 62, depressurizing the cylinder and causing the lifting platform 2 to descend.

[0055] In some embodiments, the valve island 5 is also provided with a pressure adjustment hole 55 for adjusting and controlling the pressure of the air source.

[0056] In some embodiments, a guide component is provided on the top surface of the lifting platform 2. The guide component is used to support the carrier plate and transport the carrier plate during rotation.

[0057] The guiding assembly includes guide wheel bracket assemblies and guide wheel assemblies. The guide wheel bracket assemblies have two rows, each row comprising several spaced-apart guide wheel brackets 8, which are mounted on the lifting platform 2. The guide wheel assemblies also have two rows, each row comprising several spaced-apart guide wheels 7, which are rotatably mounted on the guide wheel brackets 8. The guide wheels ensure horizontal transmission of the carrier plate on the lifting platform 2; five are arranged on each side to ensure smooth transmission and prevent derailment when the carrier plate enters the automated machine horizontally.

[0058] In some embodiments, the frame 1 includes a base plate 11 and uprights 12. A plurality of uprights 12 are provided, each upright 12 being vertically disposed on the base plate 11; a lifting mechanism is disposed on the side wall of the uprights 12. More specifically, at least four uprights 12 are provided, the four uprights 12 being respectively arranged at the four corners of the base plate 11.

[0059] In some embodiments, the frame 1 further includes longitudinal bars 15, crossbars 13, and reinforcing bars 14. At least two longitudinal bars 15 are provided, each longitudinal bar 15 being disposed on the top surface of the column 12. At least one crossbar 13 is provided, extending outwards along the longitudinal bars 15. At least one reinforcing bar 14 is provided, the reinforcing bar 14 being obliquely disposed between the crossbar 13 and the column 12, serving to strengthen the connection.

[0060] In some embodiments, the lifting platform 2 is provided with a hollow part 21, which can effectively reduce the amount of material used in making the lifting platform.

[0061] The specific working process of the aforementioned new automated carrier board mounting device is as follows:

[0062] When the lifting platform is stationary, it is supported by four columns below, and the carrier plate can be placed stationary on the guide wheels.

[0063] When the automated loading of the pallet is initiated, the cylinder is initially in the retracted state, and the lifting platform is positioned horizontally relative to the pallet box. The pallet is then driven to the lifting platform 2 via guide wheels 7. By continuously pressing the pedal manually, and through the control principle of the above components, the cylinder pushes the lifting platform up to the automated loading position, and the pallet is pushed into the machine via the guide wheels.

[0064] When the automated carrier plate is unloaded, the cylinder is initially in the extended state. The carrier plate is driven to the lifting platform by the guide wheels on the automated machine. When the pedal is pressed for a long time, the cylinder retracts and the lifting platform 2 descends to the corresponding carrier plate collection position on the carrier plate vehicle. The carrier plate is then manually transferred into the carrier plate box.

[0065] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
