Description

Technical Field

[0001] The present invention relates to the technical field of transmission equipment, and in particular to a transmission equipment and a heat treatment equipment. Background Art

[0002] In existing heat treatment furnaces such as roller-type solar cell sintering furnaces, a pair of limit support sleeves are generally arranged on the entire transmission roller, and horizontal transmission is completed under the support of two relatively arranged steps, such as Figure 1 As shown, the transmission device 100' comprises a roller 110' and a fixing seat 120'. Two support sleeves 130' are sleeved on one roller 110', and the solar cell 200' is transmitted between the two support sleeves 130'. However, the structure mainly has the following problems:

[0003] 1. The size of the solar cell 200' tends to be gradually larger. In order to match this situation, the position-limiting support sleeve 130' must be made into an independently adjustable structure. Moreover, in a high temperature environment for a long time, due to the expansion of high temperature, it is very easy to cause the entire position-limiting support sleeve 130' to loosen and shift, which in turn leads to problems such as unstable transmission and scratches of the solar cell output line.

[0004] 2. Since the entire roller 110' is used for transmission, the back of the solar cell 200' is blocked by the roller 110', which may cause hidden dangers such as poor sintering, color difference, infrared EL black spots, etc. Summary of the invention

[0084] A movable plug-in connector or a card connector is provided on the first transmission roller 110 and the second transmission roller 130, and a plurality of slots or a plurality of card slots are provided on the slideway, so that the movable plug-in connector or the card connector can be moved to disengage the plug-in connector or the card slot. After the movement is completed, the plug-in connector or the card connector is matched with the slot or the card slot to achieve fixation.

[0085] Embodiment 10:

[0086] like Figure 2 and Figure 3As shown, the transmission device 100 provided by the present invention designs the transmission roller into two sections, namely, the first transmission roller 110 and the second transmission roller 130. The middle part of the roller is vacant, that is, when the material 200 is transmitted on the roller, the middle of the material 200 remains suspended. The left and right sections of the rollers are respectively installed on a fixed seat with a bearing, and the ends of the rollers are installed with a synchronous wheel, gear or sprocket for driving. When a power with the same speed and direction is applied to the first roller of the first transmission roller 110 and the second transmission roller 130, the first roller 112 will drive the following rollers to rotate back and forth at the same speed and direction, thereby driving the solar cell (material 200) to complete horizontal transmission. When the size of the solar cell changes, it is only necessary to move the left and right sections of the rollers towards or away from each other at the same time to achieve an ideal spacing to match solar cells of different specifications.

[0087] The transmission roller is designed to be divided into two sections, namely the first transmission roller 110 and the second transmission roller 130. Each section is fixedly mounted on at least two or more fixed seats with bearings. The spacing between the fixed seats should be appropriate to meet the support function of the silicon wafers (material 200) during the transmission process. The bearings are arranged on the fixed seats at equal intervals to meet the installation of multiple rollers and realize the transmission of silicon wafers. The roller passes through the bearing on the fixed seat, and a synchronous wheel, gear or sprocket is installed at one end for driving, and a limiting sleeve (limiting member) is connected to the other end. The limiting sleeve can be fixedly connected or movably connected. There is a certain distance between the limiting sleeve and the end of the roller. The diameter of the roller within this distance range gradually decreases to form a truncated cone structure, which is used to receive the silicon wafer. The silicon wafer is in line contact with the roller during the transmission process, so that the contact area between the silicon wafer and the roller is minimized, and the roller is prevented from blocking the back of the battery cell (material 200) to the greatest extent.

[0088] The rollers on the left and right sides (the first transmission roller 110 and the second transmission roller 130) are symmetrically structured. Starting from the first roller on the left and right sides, the rollers on the left and right sides correspond to each other, that is, the central axes of the left and right rollers at the corresponding positions coincide, ensuring the stability of the silicon wafer during transmission. A certain distance is left between one end of the left roller (the first roller 112) with a truncated cone structure (the first unloading part 1120) and one end of the right roller (the second roller 132) with a truncated cone structure (the second unloading part 1320), so that during the transmission of the silicon wafer, one end is in line contact with one end of the left roller with a truncated cone structure, and the other end is in line contact with one end of the right roller with a truncated cone structure.

[0089] In order to enable the roller to transport, a power with the same rotation speed and direction needs to be applied to the first rollers 112 on the left and right sides. In order to ensure the synchronization of the movement of the left and right sides, the first roller (driving roller) can be set to be full length. The first roller rotates under the drive of the motor (driving member). The two sides of the first roller are respectively connected with the rollers on the left and right sides (the first roller 112 and the second roller 132) by means including but not limited to belts or chains or synchronous wheels, or connected to a dual-output shaft motor (driving member). The ends of the dual output shafts on both sides of the motor away from the motor are connected to the ends of the rollers on the left and right sides away from the silicon wafer by means including but not limited to belts or chains or synchronous wheels, ensuring that when a power and direction are applied to the external roller or a dual-output shaft motor is used, the transmission power and direction on the left and right sides are consistent.

[0090] When different silicon wafers need to be transported, the rollers on the left and right sides need to be moved toward or away from each other at the same time. Slide rails (slideways) can be installed on the positioning seats of the left and right rollers, and the slide rails can be adjusted to achieve the transportation of silicon wafers of different sizes.

[0091] The solar cell transmission device 100 provided by the present invention has a simple structure, reasonable design, and stable operation, so that the back of the solar cell is completely unobstructed during the drying and sintering process, and at the same time, it will not become helpless due to changes in the size of the solar cell.

[0092] Specifically, the transmission roller is designed to be divided into two sections (a first transmission roller 110 and a second transmission roller 130), so that the middle part of the roller is kept suspended, each section of the roller is mounted on two mounting seats, and a bearing is installed at each roller mounting hole of the two mounting seats. A synchronous wheel, gear or sprocket is installed on each section of the roller, and two adjacent rollers are connected by a synchronous belt, belt or chain.

[0093] When a force with the same speed and direction is applied to the first roller on the left and right sides, the first roller will drive the following rollers to rotate back and forth at the same speed and direction, thereby driving the solar cell to complete the horizontal transmission.

[0094] If the size of the solar cell changes, the ideal spacing required by the solar cell can be achieved by moving the mounting bases on both sides toward or away from each other by a corresponding distance.
