DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The contact resistance between the surface electrode and the back electrode of a photovoltaic cell has a great influence on the fill factor and conversion efficiency. The lower the metal-semiconductor contact resistance, the higher the fill factor and conversion efficiency. Therefore, the technology of reducing the metal-semiconductor contact resistance and treating cells with poor performance due to excessive contact resistance as cells with normal performance has become an urgent need for major battery manufacturers.

[0032] At present, the main way to reduce the metal-semiconductor contact resistance is the Laser Enhanced Contact Optimization (LECO) process, also known as laser-assisted sintering or laser-induced metallization. It irradiates photovoltaic cells with high-intensity lasers to excite charge carriers, and applies a deflection voltage to the photovoltaic cells to separate the carriers, forming a local current and inducing sintering to reduce the contact resistance between the metal and the semiconductor, thereby improving the conversion efficiency of the photovoltaic cells.

[0033] At present, the industry uses laser processing equipment to process products to obtain processed products. However, during the process of laser processing technology including LECO process, the direction of the product to be processed will change, resulting in the direction of the processed product being different from the direction of the product to be processed before the laser processing process. However, other processes after the laser processing process require that the processed product remain in the direction before the laser processing process.

[0034] In view of the above problems, the present application provides a transport device, which is applied to a laser processing device, and the laser processing device is configured to perform laser processing on a product to be processed to obtain a processed product. The laser processing device includes a discharge position and a plurality of work positions, and the transport device includes a first rotary drive, at least one workbench and a rotary unloading assembly. The first rotary drive is configured to provide a first rotational force in a first preset direction. The plurality of work positions are arranged in sequence around the first rotary drive. The vertical line between the geometric center of the first work position in the plurality of work positions arranged in sequence and the rotation axis of the first rotary drive is defined as a first line, and the vertical line between the geometric center of the last work position in the plurality of work positions and the rotation axis of the first rotary drive is defined as a second line. The rotation angle formed by the first line rotating around the rotation axis of the first rotary drive to the second line along the first preset direction is the first angle. At least one workbench is connected to the first rotary drive, and the workbench is configured to carry the product to be processed or the processed product. The workbench is configured to rotate from the first work position to the last work position under the drive of the first rotational force, and the product to be processed carried by the workbench is processed into a processed product at at least one work position. The rotary unloading component is arranged adjacent to the discharge position, and is configured to transfer the processed product from the last working position to the discharge position by rotation. The rotation angle of the rotary unloading component during the transfer of the processed product is the second angle. The sum of the first angle and the second angle is 360°, or the first angle is equal to the second angle. The first rotary drive and the rotary unloading component of the transport device rotate 360° in the same rotation direction, or the first rotary drive and the rotary unloading component rotate the same angle in opposite rotation directions, so that the transport device can transport the processed product to the discharge position in the direction before the laser processing process, and then the processed product can enter other processes after the laser processing process from the discharge position in the direction before the laser processing process.

[0035] At present, an auxiliary rotating mechanism can be set on the rotary unloading assembly. During the process of rotating the unloading assembly to transport the silicon wafer, the auxiliary rotating mechanism can drive the grabbing assembly that grabs the silicon wafer to rotate in the opposite direction alone, so that the direction of the processed product when entering the discharge position is the same as the direction of the processed product before the laser process. However, the structure of the rotary unloading assembly of this method is complex, and the rotation accuracy of the auxiliary rotating mechanism is high. The rotary unloading assembly of this application has a simple structure and does not need to be additionally provided with an auxiliary rotating mechanism on the rotary unloading assembly.

[0036] At present, a rotating station can also be set on the transport module after the material discharging position to adjust the direction of the processed product to the direction before the process on the transport module after the rotation, but this method requires the additional setting of one or more rotating stations on the transport module after the material discharging position, which lengthens the entire automated production line and adds additional automated transportation processes, resulting in low production efficiency of automated equipment. This application does not require the additional setting of one or more rotating stations on the transport module after the material discharging position, thereby improving the production efficiency of automated equipment.

[0069] In some embodiments, the multiple workstations 20 include at least four workstations 20, the first workstation 21 is a loading station, and the last workstation 24 is an unloading station. At least two workstations 20 among the at least four workstations 20 except the first workstation 21 and the last workstation 24 are configured to provide at least two processing positions for laser processing of the product 2 to be processed, so as to meet the needs of the laser processing equipment 1 to perform laser processing on N to-be-processed areas 210 of the product 2 to be processed at different workstations 20 respectively.

[0070] For example, Figure 3 and Figure 4As shown, the plurality of workstations 20 include four workstations 20, namely, a first workstation 21, a second workstation 22, a third workstation 23 and a last workstation 24. The first workstation 21 is a loading station, the second workstation 22 is a first laser processing station, the third workstation 23 is a second laser processing station, and the last workstation 24 is a unloading station.

Driven by the first rotary drive 100, the workbench 200 carries the product 2 to be processed and rotates from the first work position 21 to the second work position 22. A processing area 210 of the product 2 to be processed at the second work position 22 is laser processed by the laser processing equipment 1. Driven by the first rotary drive 100, the workbench 200 carries the product 2 to be processed and rotates from the second work position 22 to the third work position 23. A processing area 210 of the product 2 to be processed at the third work position 23 is laser processed by the laser processing equipment 1. At this time, the laser processing equipment 1 completes the laser processing of the two processing areas 210 of the product 2 to be processed, and the product 2 to be processed is converted into a processed product 3. Driven by the first rotary drive 100, the workbench 200 carries the processed product 3 and rotates from the third work position 23 to the last work position 24. The rotating unloading assembly 300 transfers the processed product 3 from the last work position 24 to the discharge position 30. Among them, the workbench 200 carries the product to be processed 2 or the processed product 3 and rotates each time at the same angle, which is 90 degrees, that is, the first angle α1 is 270 degrees, and the second angle α2 can be 90 degrees or 270 degrees, so that the direction of the processed product 3 at the discharge position 30 is the same as the direction of the product to be processed 2 at the first working position 21. Figure 4 The mark 32 on the product to be processed 2 or the processed product 3 indicates the change of the placement direction of the product to be processed 2 or the processed product 3.
