[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the production process of monocrystalline silicon solar cells, the raw silicon needs to be melted at high temperature in a single crystal furnace, and then the silicon solution is crystallized to form a single crystal silicon solid. The produced single crystal silicon solid is cylindrical, forming a silicon crystal rod. After the silicon crystal rod is taken out of the silicon crystal furnace, the temperature is high and the weight is heavy. The silicon crystal rod needs to be naturally cooled and transported to the cutting machine station by a transport vehicle for cutting and cutting operations. In the actual production process, the length of the produced silicon crystal rod is different due to various conditions such as different silicon crystal rod size specifications and different actual crystallization conditions of the silicon crystal rod. At present, the length of the silicon crystal rod can be about 0-6 meters. It can be seen that in the actual production process, the length of the silicon crystal rod varies greatly. In actual applications, although there are transport vehicles of different lengths, they usually have a body of a fixed length, and the length cannot be changed. It cannot be well matched with the length of the silicon crystal rod, and it is difficult to adapt to the various changes in the length of the silicon crystal rod during the production process. There is a phenomenon that longer transport vehicles transport shorter silicon crystal rods. Since the space in the transport channel is limited, the longer transport vehicles occupy the transport channel for a long time, compressing the transport space of the transport channel and reducing the efficiency of actually transporting silicon crystal rods.

[0033] To solve this problem, an embodiment of the present application provides a silicon crystal rod transport vehicle. Specifically, the silicon crystal rod transport vehicle is used to transport silicon crystal rods.

[0034] Reference Figure 1 , showing a schematic structural diagram of a silicon crystal rod transport vehicle according to an embodiment of the present application, referring to Figure 2 , showing a schematic diagram of the structure of a transport module described in an embodiment of the present application. Specifically, the silicon crystal rod transport vehicle comprises: at least two transport modules 1, and two adjacent transport modules 1 are detachably connected; the transport module 1 comprises a body 10, and a receiving frame 11 for placing silicon crystal rods is provided on the body 10, and the receiving frames 11 on the two adjacent transport modules 1 are aligned along a first direction to place the silicon crystal rods; wherein the first direction is the length direction of the silicon crystal rods.

[0035] In the embodiment of the present application, by detachably connecting multiple transport modules 1, multiple transport modules 1 can be selected according to the specific length of the silicon crystal rod to be connected to transport the silicon crystal rod, so that the silicon crystal rod transport vehicle can match the actual length of the silicon crystal rod, avoiding the problem of compression of the transport channel caused by using a longer transport vehicle to transport shorter silicon crystal rods, thereby improving the transportation efficiency of the silicon crystal rods.

[0036] In specific applications, such as Figure 2 As shown, the vehicle body 10 and the receiving frame 11 may be an integrated structure. The vehicle body 10 and the receiving frame 11 are rigid structures as a whole, and rollers are connected to the four corners of the bottom of the vehicle body 10 respectively.

[0037] Reference Figure 1 The vehicle body 10 is provided with a connecting component 12, and the connecting component 12 is used to connect the two adjacent transport modules 1.

[0038] In a specific application, a connecting component 12 is provided on the vehicle body 10, and adjacent transport modules 1 are connected through the connecting component 12, so that a plurality of transport modules 1 can be selected according to the specific length of the silicon crystal rod to be connected and transport the silicon crystal rod, so that the silicon crystal rod transport vehicle can match the actual length of the silicon crystal rod, thereby improving the transportation efficiency of the silicon crystal rod.

[0039] Optionally, refer to Figure 1 , refer to Figure 3 , showing Figure 2 Side view of the transport module shown, see Figure 4 , showing Figure 2 The connecting assembly 12 comprises a connecting arm 120 and a connecting pin 121, wherein two connecting arms 120 corresponding to two adjacent vehicle bodies 10 are superimposed, and the connecting pin 121 passes through the two connecting arms 120 in sequence to connect the two adjacent transport modules 1.

[0040] In actual applications, since the connection through the connecting arm 120 and the connecting pin 121 is a simple and detachable connection method, when the connecting arms 120 of two adjacent car bodies 10 overlap up and down, the two adjacent transport modules 1 can be connected by inserting the connecting pin 121 into the two connecting arms 120, and the connected transport modules 1 can be disassembled by pulling out the connecting pin 121, thereby improving the operational convenience of connecting or disassembling multiple adjacent transport modules 1.

[0041] Optionally, the connecting assembly 12 includes a pull ring and a hook; one of the two adjacent vehicle bodies 10 is provided with the pull ring and the hook connected to the pull ring, and the other vehicle body 10 is provided with the pull ring, and the hook is hooked on the pull ring, so as to connect the two adjacent transport modules 1.

[0042] In specific applications, since the hook connection is a simpler detachable connection method, the two adjacent transport modules 1 are connected by hooking the hook on the pull ring, and the hook is removed to cancel the connection between the two adjacent modules, thereby further improving the operational convenience of connecting or disassembling multiple adjacent transport modules 1.

[0043] It should be noted that, in a specific application, the connection between two adjacent transport modules 1 may also be a variety of connection modes such as magnetic connection, chain connection, etc., and the corresponding components included in the corresponding connection assembly 12 may be different. Figure 1 In the figure, only the case where the connecting component 12 includes a connecting arm 120 and a connecting pin 121 is shown, and the connecting component 12 can be specifically set according to actual conditions.

[0044] like Figure 2 As shown, optionally, the accommodating rack includes a first placement slot and a second placement slot which are vertically arranged, and the two first placement slots corresponding to the two adjacent transport modules are aligned along the first direction, or the two second placement slots corresponding to the two adjacent transport modules are aligned along the first direction, or one of the two adjacent transport modules corresponds to the first placement slot and the other corresponds to the second placement slot, and the first placement slot is aligned with the second placement slot along the first direction.

[0045] In practical applications, by arranging the first placement slot 110 and the second placement slot 111 in the vertical direction respectively, the placement slots on two adjacent transport modules 1 can be arbitrarily combined, thereby improving the operational convenience of the silicon ingot transport vehicle.

[0046] Optionally, the first placement groove 110 and the second placement groove 111 are V-shaped grooves.

[0047] In a specific application, the placement groove is set as a V-shaped groove. The V-shaped placement groove can well meet the structural requirements of the cylindrical silicon crystal rod, so that the silicon crystal rod can be stably placed on the silicon crystal rod transport vehicle, thereby improving the stability of the silicon crystal rod during transportation.

[0048] Optionally, a fixing piece is provided on the V-shaped groove to fix the silicon crystal rod.

[0049] In practical applications, by arranging fixings on the V-grooves, the silicon crystal rods are fixed on the silicon crystal rod transport vehicle through the fixings during the transportation of the silicon crystal rods, thereby avoiding the instability during the transportation of the silicon crystal rods causing the silicon crystal rods to fall, and further improving the stability of the silicon crystal rod transportation process.

[0050] Optionally, the fixing member is a buckle or a retractable belt.

[0051] In practical applications, a buckle or a retractable belt is provided on the contact portion between the V-shaped groove and the silicon crystal rod, and the silicon crystal rod can be fixed inside the V-shaped groove by the buckle or the retractable belt. In practical applications, since the buckle or the retractable belt is the most common fixing part, the operation method for fixing is also very simple, which not only makes the structure of the silicon crystal rod transport vehicle simpler and saves costs, but also improves the convenience of the fixing operation.

[0052] Optionally, a pad is provided on a portion of the V-shaped groove that contacts the silicon crystal rod.

[0053] In practical applications, when the silicon crystal rod is produced from the single crystal furnace and placed on the silicon crystal transport vehicle, it usually has a high temperature and a smooth round outer surface. The high temperature directly contacts the transport vehicle, which will damage the V-groove, thereby reducing the service life of the transport module 1. The smooth surface will make the friction force and contact area of ​​the contact part with the silicon crystal rod smaller, making the stability of the silicon crystal rod during transportation poor. In practical applications, by setting a pad at the part where the V-groove contacts the silicon crystal rod, not only the direct contact between the V-groove and the silicon crystal rod is avoided, and the service life of the silicon crystal rod transport vehicle is improved, but also the area and friction of the contact part between the silicon crystal rod and the V-groove can be increased, further improving the stability of the silicon crystal rod during transportation.

[0054] Optionally, the material of the pad block is a heat-insulating material or an anti-slip material.

[0055] Specifically, the thermal insulation material can be any material with a thermal insulation function. Exemplarily, the thermal insulation material can be glass fiber, asbestos, rock wool, silicate, etc. The anti-slip material can be any material with an anti-slip function; exemplary, the anti-slip material can be rubber, polyvinyl chloride, silicone, etc.

[0056] In practical applications, the provision of heat-insulating materials or anti-slip materials not only avoids direct contact between the V-groove and the silicon crystal rod, thereby increasing the service life of the silicon crystal rod transport vehicle, but also increases the contact area and friction between the silicon crystal rod and the V-groove, thereby further improving the stability of the silicon crystal rod during transportation.

[0057] The specific transportation process of the silicon crystal rod transport vehicle in the embodiment of the present application is divided into two cases, namely, transporting long silicon crystal rods and transporting short silicon crystal rods, according to the length of the silicon crystal rods:

[0058] Reference Figure 5 , shows a schematic diagram of the state of a silicon crystal rod transport vehicle for transporting short silicon crystal rods according to an embodiment of the present application. When the silicon crystal rod transport vehicle transports short silicon crystal rods, the short silicon crystal rods are placed on the transport module 1 through a transport module 1, and the silicon crystal rod transport vehicle is pushed to a designated location by an on-site operator or a tractor to complete the transport operation.

[0059] Reference Figure 6 , showing a schematic diagram of the state of a silicon crystal rod transport vehicle for transporting long silicon crystal rods according to an embodiment of the present application. When the silicon crystal rod transport vehicle transports long silicon crystal rods, a suitable number of transport modules 1 suitable for the length of the long silicon crystal rods are selected, and multiple transport modules 1 are respectively connected through connecting components 12, and then multiple transport modules 1 are aligned and arranged neatly along the length direction of the silicon crystal rods, and the silicon crystal rods are placed on the multiple transport modules 1, and the silicon crystal rod transport vehicle is pushed to the designated location by an on-site operator or a tractor to complete the transportation operation.

[0060] It should be noted that Figure 6 The figure is only used to represent a transportation state of the silicon crystal rod transport vehicle for transporting long silicon crystal rods. For the sake of clarity and specificity, only the head and tail transportation modules 1 are shown. In actual applications, at least two transportation modules 1 can be selected for connection according to the length of the silicon crystal rod. For example, 2, 3, 4, etc. transportation modules 1 are selected.

[0061] The silicon ingot transport vehicle described in the application embodiment may include at least the following advantages:

[0062] In the embodiment of the present application, by detachably connecting multiple transport modules 1, multiple transport modules 1 can be selected according to the specific length of the silicon crystal rod to be connected to transport the silicon crystal rod, so that the silicon crystal rod transport vehicle can match the actual length of the silicon crystal rod, avoiding the problem of compression of the transport channel caused by using a longer transport vehicle to transport shorter silicon crystal rods, thereby improving the transportation efficiency of the silicon crystal rods.
