Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell silicon wafer technology, specifically a transport vehicle for photovoltaic cell silicon wafers. Background Technology

[0002] Transport vehicles for photovoltaic silicon wafers are core equipment ensuring the safety of silicon wafers during production and transportation. They are specifically designed for the "thin, brittle, and easily damaged" characteristics of silicon wafers. Their core functions are scratch protection, collision protection, and environmental control. Mainstream vehicles are divided into two categories: one is rigid vehicles, such as quartz boats and silicon carbide boats, which are resistant to high temperatures and have high stability, and are mostly used for transportation within production processes such as silicon wafer cleaning and coating; the other is soft / semi-rigid vehicles, such as blister boxes and EVA buffer trays, which are equipped with anti-static materials to isolate electrostatic damage and are suitable for long-distance transportation between workshops and factories. The design of vehicles must meet three major requirements: high cleanliness, precise size adaptation, and reusability. They are key components for reducing costs and increasing efficiency in the photovoltaic industry chain and ensuring product yield.

[0003] Chinese Utility Model Patent Publication No. CN219407415U discloses a transport device for transporting silicon wafer carriers. The device's specification describes a system where a fragment collection box is detachably connected to the bottom plate of the loading chamber. After sweeping silicon wafer fragments into the collection box, the box can be detached from the bottom plate to empty the fragments. This achieves the technical effect of easily cleaning up silicon wafer fragments that fall from the carrier into the loading chamber. However, this transport device lacks a limiting structure for photovoltaic silicon wafers. During transport, the silicon wafers are prone to shaking, leading to damage and economic losses. Furthermore, the lack of a sealing structure prevents external moisture and dust from contacting the silicon wafers, which can affect their performance. Overall, the device has poor sealing, limited practicality, and is not suitable for widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a transport carrier for photovoltaic silicon wafers. It can effectively solve the problems in the prior art, which does not have a limiting structure for photovoltaic silicon wafers. During transportation, the photovoltaic silicon wafers are prone to shaking, resulting in damage and economic losses. In addition, the lack of a sealing structure prevents external moisture and dust from easily contacting the photovoltaic silicon wafers, which makes the performance of the photovoltaic silicon wafers easily affected. The overall sealing performance is poor, the practicality is poor, and it is not convenient for widespread use.

[0005] The technical solution adopted by the utility model is: a transportation carrier for photovoltaic cell silicon wafers, comprising a lower shell and an upper shell. One end of the upper shell close to the lower shell is fixedly provided with a first positioning block, a second positioning block and a buckle. An installation groove is formed on an outer wall of the second positioning block, and a sealing ring is arranged on an inner wall of the installation groove. One end of the lower shell close to the upper shell is provided with a first positioning groove, a second positioning groove and a clamping groove. A storage groove is formed on an inner wall of the lower shell, and an elastic block is arranged on an inner wall of the storage groove.

[0006] Preferably, the cross-section of the storage groove has a "circular arc" shaped structure, a plurality of identical storage grooves are provided, and the plurality of storage grooves are distributed at equal intervals.

[0007] Through the above technical solution, the design of a plurality of storage grooves can load a plurality of photovoltaic cell silicon wafers at the same time, improving transportation efficiency, and can avoid mutual stacking, extrusion or displacement of photovoltaic cell silicon wafers during transportation. Meanwhile, it is convenient for workers to place and take out photovoltaic cell silicon wafers quickly and accurately, reducing manual operation errors.

[0008] Preferably, the elastic blocks are made of silica gel material, a plurality of identical elastic blocks are provided, and the plurality of elastic blocks are distributed in an annular shape.

[0009] Through the above technical solution, the elastic block made of silica gel material has excellent elasticity and toughness. After the photovoltaic cell silicon wafer is loaded, the elastic block fits against the outer wall of the photovoltaic cell silicon wafer, playing a certain fixing role. During transportation, it prevents the photovoltaic cell silicon wafer from shaking to cause damage to the silicon wafer, which would result in economic loss. The design of a plurality of elastic blocks enables the photovoltaic cell silicon wafer to be stressed more evenly, further reducing the risk of damage and having high practicability.

[0010] Preferably, the first positioning block and the first positioning groove are installed by plugging, the second positioning block and the second positioning groove are installed by plugging, and the cross-section of the second positioning block has a "square-ring" shaped structure.

[0011] Through the above technical solution, a worker inserts the first positioning block into the first positioning groove and inserts the second positioning block into the second positioning groove at the same time, so as to realize rapid positioning of the upper shell and the lower shell.

[0012] Preferably, the lower shell is adapted to the upper shell, and the buckle is adapted to the clamping groove.

[0013] Through the above technical solution, during the process of quickly positioning the upper and lower housings, when the buckle contacts the lower housing, the buckle deforms. When the positioning block is fully submerged in the positioning groove, the buckle returns to its original shape, allowing the buckle to engage with the groove. This enables the upper and lower housings to be quickly connected. In use, it is convenient for staff to separate or close the upper and lower housings, greatly simplifying the operation process and saving loading and unloading time.

[0014] Preferably, the sealing ring is made of rubber, and three identical sealing rings are provided, with the three sealing rings distributed at equal intervals.

[0015] The above technical solution utilizes a rubber sealing ring, which has excellent sealing and elasticity, preventing external moisture and dust from entering the lower housing through the connection between the lower and upper housings. This provides more reliable moisture and dust protection for the photovoltaic silicon wafers. The design of three sealing rings further enhances the overall sealing performance, ensuring that the photovoltaic silicon wafers are in a dry and clean environment throughout the transportation process, thus protecting their performance from external environmental influences and demonstrating high practicality.

[0016] Preferably, both the lower and upper shells are made of polyetherimide.

[0017] Through the above technical solution, the lower and upper shells made of polyetherimide material have excellent mechanical strength, high temperature resistance, corrosion resistance and impact resistance, thus extending the service life of the lower and upper shells.

[0018] Compared with the prior art, this utility model provides a transport vehicle for photovoltaic silicon wafers, which has the following beneficial effects:

[0019] 1. This photovoltaic silicon wafer transport vehicle, with its multiple storage slots, can simultaneously load multiple photovoltaic silicon wafers, improving transport efficiency and preventing the silicon wafers from stacking, squeezing, or shifting during transport. It also facilitates quick and accurate placement and removal of the silicon wafers by workers, reducing human error. The elastic blocks made of adhesive material possess excellent elasticity and toughness. After loading the silicon wafers, the elastic blocks adhere to the outer wall of the wafers, providing a certain degree of fixation. During transport, this prevents the silicon wafers from shaking and being damaged, resulting in economic losses. The multiple elastic blocks design ensures more even force distribution on the silicon wafers, further reducing the risk of damage and demonstrating high practicality.

[0020] 2. This photovoltaic silicon wafer transport carrier, through the design of positioning block one and positioning groove one, and positioning block two and positioning groove two, can achieve rapid positioning of the upper and lower shells. Combined with buckles and slots, it can achieve rapid connection between the upper and lower shells. During use, it is convenient for workers to separate or close the upper and lower shells, greatly simplifying the operation process and saving loading and unloading time. The sealing rings made of rubber have good sealing performance and elasticity, preventing external moisture and dust from entering the interior of the lower shell through the connection between the upper and lower shells, providing more reliable moisture and dust protection for the photovoltaic silicon wafers. The design of three sealing rings further improves the overall sealing performance, ensuring that the photovoltaic silicon wafers are in a dry and clean environment throughout the transportation process, protecting their performance from external environmental influences. It has high practicality. The lower and upper shells, made of polyetherimide, have excellent mechanical strength, high temperature resistance, corrosion resistance, and impact resistance, extending the service life of the lower and upper shells.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] like Figure 1-5As shown, the present utility model provides a transport carrier for photovoltaic cell silicon wafers, comprising a lower shell 1 and an upper shell 2. A first positioning block 3, a second positioning block 4 and a buckle 5 are fixedly mounted at an end of the upper shell 2 close to the lower shell 1. An installation groove 6 is provided on an outer wall of the second positioning block 4, and a sealing ring 7 is provided on an inner wall of the installation groove 6. A first positioning groove 8, a second positioning groove 9 and a clamping groove 10 are provided at an end of the lower shell 1 close to the upper shell 2. A storage groove 11 is provided on an inner wall of the lower shell 1, and an elastic block 12 is provided on an inner wall of the storage groove 11.

[0030] Specifically, the cross-section of the storage grooves 11 is in an "arc" shape structure, a plurality of identical storage grooves 11 are provided, and the plurality of storage grooves 11 are distributed at equal intervals. The advantage is that through the design of the plurality of storage grooves 11, a plurality of photovoltaic cell silicon wafers can be loaded at the same time, which improves transport efficiency, and can avoid mutual stacking, extrusion or displacement of the photovoltaic cell silicon wafers during transport. At the same time, it is convenient for staff to place and take out the photovoltaic cell silicon wafers quickly and accurately, which reduces manual operation errors.

[0031] Specifically, the elastic blocks 12 are made of silica gel, a plurality of identical elastic blocks 12 are provided, and the plurality of elastic blocks 12 are distributed in an annular shape. The advantage is that the elastic blocks 12 made of silica gel have excellent elasticity and toughness. After the photovoltaic cell silicon wafers are loaded, the elastic blocks 12 fit with the outer walls of the photovoltaic cell silicon wafers, which plays a certain role in fixing. During transport, it prevents the photovoltaic cell silicon wafers from shaking, which causes damage to the silicon wafers and results in economic losses. Through the design of the plurality of elastic blocks 12, the stress on the photovoltaic cell silicon wafers is more uniform, which further reduces the risk of damage and has high practicability.

[0032] Specifically, both the lower shell 1 and the upper shell 2 are made of polyetherimide. The advantage is that the lower shell 1 and the upper shell 2 made of polyetherimide have excellent mechanical strength, high temperature resistance, corrosion resistance and impact resistance, which prolongs the service life of the lower shell 1 and the upper shell 2.

[0033] Embodiment 2:

[0034] As Figure 2-5 shown, as an improvement to the previous embodiment, in order to further facilitate the connection of the upper shell 2 and the lower shell 1, specifically, the first positioning block 3 and the first positioning groove 8 are installed by plugging, the second positioning block 4 and the second positioning groove 9 are installed by plugging, and the cross-section of the second positioning block 4 is in a "hollow square" shape structure. The advantage is that staff can insert the first positioning block 3 into the first positioning groove 8, and insert the second positioning block 4 into the second positioning groove 9 at the same time, so as to realize rapid positioning of the upper shell 2 and the lower shell 1.

[0035] Specifically, the lower housing 1 is adapted to the upper housing 2, and the buckle 5 is adapted to the slot 10. The advantage is that during the rapid positioning of the upper housing 2 and the lower housing 1, when the buckle 5 contacts the lower housing 1, the buckle 5 deforms. When the positioning block 3 is completely submerged in the positioning groove 8, the buckle 5 returns to its original shape, allowing it to engage with the slot 10. This enables a rapid connection between the upper housing 2 and the lower housing 1. During use, it facilitates the separation or closure of the upper housing 2 and the lower housing 1 by operators, significantly simplifying the operation process and saving loading and unloading time.

[0036] Specifically, the sealing ring 7 is made of rubber, and three identical sealing rings 7 are arranged at equal intervals. The advantage is that the rubber sealing ring 7 has good sealing performance and elasticity, preventing external moisture and dust from entering the interior of the lower housing 1 through the connection between the lower housing 1 and the upper housing 2. This provides more reliable moisture and dust protection for the photovoltaic silicon wafer. The design of three sealing rings 7 further enhances the overall sealing performance, ensuring that the photovoltaic silicon wafer remains in a dry and clean environment throughout transportation, protecting its performance from external environmental influences, and demonstrating high practicality.

[0037] Working Principle: During use, the operator inserts the photovoltaic silicon wafers into the storage slot 11, enabling rapid storage. The design of multiple storage slots 11 allows for the simultaneous loading of multiple photovoltaic silicon wafers, improving transportation efficiency and preventing the wafers from stacking, being squeezed, or shifting during transport. It also facilitates quick and accurate placement and removal of the wafers, reducing human error. The elastic blocks 12, made of a rubber material, possess excellent elasticity and toughness. After loading the silicon wafers, the elastic blocks 12 adhere to the outer wall of the wafers, providing a certain degree of fixation. This prevents the wafers from shaking during transport, thus avoiding damage and economic losses. The multiple elastic blocks 12 design ensures more even force distribution on the wafers, further reducing the risk of damage and enhancing practicality. After loading the silicon wafers, the operator inserts positioning block 3 into positioning slot 8 and positioning block 4 into positioning slot 9, enabling rapid positioning of the upper shell 2 and lower shell 1. In the process of quickly positioning the upper housing 2 and the lower housing 1, when the buckle 5 contacts the lower housing 1, the buckle 5 deforms. When the positioning block 3 is completely submerged in the positioning groove 8, the buckle 5 returns to its original shape, allowing the buckle 5 to engage with the groove 10, thus enabling a quick connection between the upper housing 2 and the lower housing 1. During use, it is convenient for staff to separate or close the upper housing 2 and the lower housing 1, greatly simplifying the operation process and saving loading and unloading time. The sealing ring 7, made of rubber, has good sealing performance and elasticity, preventing external moisture and dust from entering the interior of the lower housing 1 through the connection between the lower housing 1 and the upper housing 2, providing more reliable moisture and dust protection for the photovoltaic silicon wafer. The design of three sealing rings 7 further improves the overall sealing performance, ensuring that the photovoltaic silicon wafer is in a dry and clean environment throughout the transportation process, ensuring that its performance is not affected by the external environment, and has high practicality. The lower housing 1 and the upper housing 2, made of polyetherimide, have excellent mechanical strength, high temperature resistance, corrosion resistance and impact resistance, extending the service life of the lower housing 1 and the upper housing 2.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
