DETAILED DESCRIPTION

[0032] In order to enable a more detailed understanding of the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure is described in detail below, and the accompanying drawings are used for reference only and do not limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, a plurality of details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be simplified to facilitate the drawings.

[0033] The terms "first", "second", and the like in the specification and claims of the embodiments of the present disclosure and the above drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0034] In the embodiments of the present disclosure, the terms "upper", "lower", "inner", "middle", "outer", "front", "back", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the embodiments of the present disclosure and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation. In addition, in addition to indicating the orientation or positional relationship, the above-mentioned terms can also be used to indicate other meanings, for example, the term "upper" can also be used to indicate a certain attachment relationship or connection relationship in some cases. For those skilled in the art, the specific meaning of these terms in the embodiments of the present disclosure can be understood according to the specific circumstances.

[0035] In addition, the terms "set", "connected", "fixed" should be broadly understood. For example, "connected" can be fixedly connected, detachably connected, or integrally configured; can be mechanically connected, or electrically connected; can be directly connected, or indirectly connected through an intermediate medium, or internal communication between two devices, elements or components. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present disclosure can be understood according to the specific circumstances.

[0036] Unless otherwise specified, the term "a plurality of" means two or more.

[0037] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the objects before and after it. For example, A / B represents: A or B.

[0038] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B, which means: A or B, or, A and B, the three relationships.

[0039] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0040] In the related art, the existing cache mechanism is usually provided with one or more cache platforms for placing a carrier (hereinafter taking a quartz boat as an example), and each cache platform is composed of a pair of cache supports. The cache support realizes the rotating action of the cantilever support through a rotating shaft, and keeps the cantilever support in an upturned state through a spring plunger. In this state, the micro switch is not in contact with the feedback.

[0041] When the cache support is placed with the quartz boat, the quartz boat is adjusted to be placed in a suitable position through a deviation correction roller, and the support roller plays a role in fixing the quartz boat. After the quartz boat is placed on the cache support, the entire cantilever support is changed from the upturned state under the action of the gravity of the quartz boat to a horizontal state, and the spring plunger is compressed, so that the cantilever support triggers the micro switch, and the signal feedback that the cache support is placed with the quartz boat is realized.

[0042] It can be seen that in the related art, the cache mechanism can realize the detection function of whether there is a boat on the cache platform, but in the use process, the function can be realized only through the action of external force such as rotation, compression, rebound, and pressure touch, which changes the nature of the detection component. Long-term use will cause the detection component to have poor structural stability, short service life of parts, frequent maintenance and replacement of parts, difficult operation, and thus unnecessary losses.

[0043] In view of the above technical problems, in combination with Figure 1 and Figure 2 The present disclosure provides a carrier cache system for a photovoltaic device to realize non-contact detection feedback of the cache mechanism 5, which comprises a frame body 1, a cache bearing mechanism 2, and a carrier detection device 3. The cache bearing mechanism 2 is arranged on the frame body 1 and is used for placing a carrier 4. The carrier detection device 3 is arranged on the frame body 1 and works independently of the cache bearing mechanism 2. The carrier detection device 3 detects whether the cache bearing mechanism 2 is placed with the carrier 4 through a non-contact mode.

[0044] The carrier cache system for a photovoltaic device provided by the present disclosure can realize independent work of the cache bearing mechanism and the carrier detection device, and can realize the detection function through non-contact detection of the carrier without contact through mechanism action. This can effectively solve the problems of deformation of the detection mechanism, poor stability, short service life of parts, frequent maintenance and replacement, and the like caused by external force contact such as rotation, compression, rebound, or pressure touch in the long-term use process, thereby improving the detection stability and the service life of the parts, and reducing the redundant design and unnecessary losses.

[0045] Optionally, in combination withFigure 1 As shown in the drawings, one or more buffer bearing mechanisms 2 are arranged on the frame body 1, and each buffer bearing mechanism 2 is respectively provided with a carrier detection device 3, which is installed at a position facing the carrier 4 and does not interfere with the carrier detection device 3 during the buffering process.

[0046] That is, the carrier detection device 3 of the present application and the buffer bearing mechanism 2 can realize independent operation and mutual cooperation. In this way, the carrier detection device 3 does not need to realize the detection function through mechanical action, and can effectively solve the problems of deformation caused by mechanical action, poor stability, short service life of parts, frequent maintenance and replacement, etc. in the long-term use process.

[0047] Optionally, in combination with Figure 2 As shown, the carrier 4 of the present application is provided with a reflection part 41, and in the case that the carrier 4 is placed in the buffer position, the carrier detection device 3 detects the reflection part 41 and makes signal feedback.

[0048] For example, the carrier detection device 3 can be a photoelectric sensor, and the reflection part 41 can be milky quartz or ceramic arranged on the carrier 4. In actual application, the photoelectric sensor is in a normally open working state, and when the carrier 4 is placed in the buffer position, the photoelectric sensor receives a signal and makes signal feedback. Because the quartz material will become transparent after multiple high-temperature processes, the photoelectric signal cannot be reflected, so it is necessary to set milky quartz or ceramic at the reflection position of the photoelectric sensor, thereby improving the stability of detection.

[0049] Optionally, in combination with Figure 2 As shown, the carrier buffering system of the present application further comprises a protective plate assembly 14 arranged on the frame body 1 and located below the buffer bearing mechanism 2. In actual application, the protective plate assembly 14 generally comprises a falling prevention protective plate and a protective plate support, and each buffer bearing mechanism 2 is provided with one falling prevention protective plate and one protective plate support. The protective plate support is usually designed as a hollow design and is not used to directly place the carrier 4, and the design purpose is to prevent the carrier 4 falling from the upper buffer bearing mechanism 2 from falling on the carrier 4 of the next layer. At the same time, a cooling mechanism can also be arranged on the protective plate support to cool the carrier 4 buffered in the upper buffer bearing mechanism 2. In addition, maintenance personnel can step on the protective plate support to perform climbing maintenance and maintenance on the carrier buffering system.

[0050] At the same time, in combination with Figure 3As shown, the embodiment of the present disclosure further provides a cache bearing mechanism, applied to the carrier cache system of the present application, comprising a fixed plate 21, a moving plate 23 and a buffer assembly 24, wherein the fixed plate 21 is fixedly connected with the frame 1 of the carrier cache system. The moving plate 23 is movably connected to the fixed plate 21 and can move linearly back and forth along the fixed plate 21. The buffer assembly 24 is arranged on the moving plate 23 and is used for supporting the carrier 4.

[0051] In this way, the cache bearing mechanism of the present application works independently and is only used to realize the cache function. The carrier detection device uses non-contact detection and does not need to contact through mechanism action to realize the detection function. The structure optimization can be realized under the premise of ensuring the stability of the mechanism, the redundant design is reduced, and the stability of the detection is improved.

[0052] Optionally, in combination with Figure 3 As shown, the cache assembly of the present application comprises a buffer assembly 24, a deviation correction wheel 25, a first support assembly 26 and a second support assembly 27, wherein the buffer assembly 24 is arranged at the middle part of the moving plate 23 and is used for buffering the carrier 4 when supporting the carrier 4 and placing the carrier 4. The deviation correction wheel 25 is arranged at the middle part of the moving plate 23 and is located above the buffer assembly 24, and is used for adjusting the position of the carrier 4 when placing the carrier 4. The first support assembly 26 is arranged on the moving plate 23 and is located on both sides of the buffer assembly 24. The second support assembly 27 is arranged on the moving plate 23 and is located at both ends of the moving plate 23. The first support assembly 26 and the second support assembly 27 are adjusted in position by the moving part 29 prearranged on the moving plate 23.

[0053] In this way, in combination with Figure 4 and Figure 5 As shown, the present application can buffer the carrier 4 through the buffer assembly 24 and adjust the position of the carrier 4 through the deviation correction wheel 25, the first support assembly 26 and the second support assembly 27, so as to accurately adjust the specific position of the carrier 4 in the cache process and facilitate the accurate grabbing of the mechanical hand. For example, in specific applications, the buffer assembly 24 of the present application can carry graphite boats and quartz boats, and the present application is not limited in specific.

[0054] Optionally, in combination with Figure 3 As shown, the cache bearing mechanism 2 of the present application further comprises a wire rail 22 and a handle 28, wherein the wire rail 22 is fixedly installed on the fixed plate 21 and is slidably connected with the moving plate 23. The handle 28 is arranged at the end of the moving plate 23.

[0055] In one embodiment of the present application, the fixed plate 21 of the present application can be a stationary fixing device, the fixed plate 21 is connected with the linear rail 22 through bolts, the linear rail 22 comprises two sliding blocks (not shown in the figure) which are slidingly connected with the moving plate 23. In this way, the reciprocating linear motion of the moving plate 23 can be realized through the linear rail 22. Meanwhile, the present application is equipped with the handle 28 on the moving plate 23, so that it is more convenient for the manual reciprocating motion. Specifically, as shown in Figure 6 and Figure 7 shown, the staff can slide the moving plate 23 from the inside of the rack (or machine table) to the outside of the rack (or machine table) through the handle 28, so as to carry out relevant work on the carrier 4 on the buffer assembly 24.

[0056] Meanwhile, as shown in Figure 3 , the moving plate 23 of the present application is installed with the buffer assembly 24, the deviation correction wheel 25, the first supporting assembly 26 and the second supporting assembly 27. Specifically, when placing the carrier 4 (such as a quartz boat), the buffer assembly 24 of the present application plays a carrier buffering role through the spring arranged in it. The deviation correction wheel 25 of the present application can be a roller device, which can realize position fine adjustment through the waist hole fixing, and plays a role of preventing the quartz boat from deviating and limiting when placing the boat. The first supporting assembly 26 and the second supporting assembly 27 of the present application can be rollers, which are provided with a moving part 29 in the horizontal direction of the moving plate 23, and the first supporting assembly 26 and the second supporting assembly 27 can carry out position fine adjustment through the moving part 29, so as to realize the role of preventing the carrier 4 from deviating and limiting when placing the carrier 4. In addition, the carrier detection device 3 can be a photoelectric sensor, so as to realize the detection of whether there is a carrier 4 placed on the buffer support 7.
