Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a silicon ingot frame. Background Art

[0002] In the field of photovoltaic power generation, common crystalline silicon solar cells are made on high-quality silicon wafers, which are cut from pulled or cast silicon ingots by multi-wire saws. During the transportation process, the silicon ingots are transported by a material frame, which carries the silicon ingots between different workstations.

[0003] For the material frame, a clamping assembly for clamping the silicon ingot is provided inside. During its use, the clamping assembly needs to switch between two states: clamping the silicon ingot and releasing the clamping of the silicon ingot. Therefore, the clamping assembly needs to cooperate with a control assembly that can realize its movement, and the control assembly is used to realize the switching of the use state of the clamping assembly.

[0004] In this regard, for example, the announcement number CN216928521U discloses an automatic material frame for debonding single crystal silicon material, which includes a frame and an elastic clamping assembly arranged in the frame, and the elastic clamping assembly is used to clamp the single crystal silicon material; wherein the elastic clamping assembly includes clamping rods symmetrically arranged on both sides of the frame, and the frame 1 is provided with slide grooves corresponding to the ends of the clamping rods, and the slide grooves are all arranged in the horizontal direction, and the ends of the clamping rods can slide through the corresponding slide grooves, and the ends of the clamping rods are sleeved with connecting pieces, and the two connecting pieces at the same end are connected by tension springs. The two clamping rods are kept in a clamped state under the elastic action of the tension springs between the ends, and when the silicon wafer to be debonded is placed, the automatic loader pulls the two clamping rods apart to allow the silicon wafer to fall smoothly.

[0005] For the above automatic material frame, an automatic loader is needed to pull the two clamping rods apart to release the clamping of the single crystal silicon material, and the single crystal silicon material is clamped between the two clamping rods. In this process, the automatic loader may collide with the single crystal silicon material when pulling the two clamping rods. Based on this situation, in order to reduce the collision of the silicon material during the process of releasing the clamping of the silicon material, it is necessary to further optimize its structure for the process of releasing the clamping of the silicon material.

DETAILED DESCRIPTION

[0035] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0036] See also Figures 1 to 6 As shown, this embodiment provides a silicon ingot material frame, including: a material frame body 1 and a clamping assembly and a rocker brake assembly arranged on the material frame body 1. The material frame body 1 has a material cavity 11 for accommodating silicon ingots, and the material cavity 11 is roughly shaped like a rectangular structure suitable for conventional silicon ingots.

[0037] The clamping assembly includes a pair of clamping rods 2 arranged in opposite directions in the cavity 11, and a pair of rocking arms 3 used in one-to-one cooperation with the pair of clamping rods 2 and rotatably connected to the side wall of the cavity 11. The pair of clamping rods 2 are arranged along the length direction of the cavity 11, so as to achieve the clamping of the silicon ingot placed in the cavity 11 in the length direction.

[0038] On the basis of the above structure, the clamping rod 2 is adapted to operate synchronously with the rotation of the rocker 3, and the clamping of the silicon ingot is realized by the relative contraction of the pair of clamping rods 2, and the clamping of the silicon ingot is released by the relative opening of the pair of clamping rods 2. In other words, the key to the clamping and releasing of the silicon ingot lies in the control of the relative state of the pair of clamping rods 2. In this embodiment, the switching control of the working state of the pair of clamping rods 2 is realized by the pair of rockers 3, that is, the synchronous movement of the clamping rods 2 is realized by the rotation of the rocker 3.

[0039] Based on the above situation, each rocker 3 is connected with at least one pair of connecting pieces 4 suitable for synchronously rotating with the rocker 3, and the connecting pieces 4 are connected with the clamping rod 2, so that the clamping rod 2 runs synchronously with the rotation of the rocker 3. Based on this structure, when the rocker 3 rotates, the clamping rod 2 moves in an arc around the rocker 3 with the connecting piece 4 as the radius. In this process, the rotation of the rocker 3 is the driving force for the circular motion of the clamping rod 2.

[0040] Here, it is also necessary to explain that a clamping area for clamping the silicon ingot is formed between a pair of clamping rods 2 that are relatively retracted; and the side end surface of each clamping rod 2 facing the clamping area protrudes from the side end surface of the rocker 3 facing the clamping area. In other words, when the pair of clamping rods 2 are relatively open, the clamping area is released. In this regard, specifically, since the rocker 3 is mainly used to generate power for the operation of the clamping rod 2, and the rocker 3 does not bear the support for the silicon ingot, and does not need to contact the silicon ingot, in an optional implementation, each rocker 3 is located below the corresponding clamping rod 2, and the outer diameter of each rocker 3 is smaller than the outer diameter of the corresponding clamping rod 2.

[0041] Furthermore, the rotational movement of the rocker 3 is achieved by the rocker brake assembly in this embodiment:

[0042] Next, an optional rocker brake assembly is given as an example in conjunction with the accompanying drawings, which includes a pair of rocker linkage blocks 5 arranged outside the material cavity 11 and connected to the outer side wall of the material frame body 1 for rotation, and a power structure for driving the pair of rocker linkage blocks 5 to rotate relative to the outer side wall of the material frame body 1; each rocker 3 penetrates the side wall of the material frame body 1 and is connected to a rocker linkage block 5. The rocker 3 forms a rotational matching relationship with the side wall of the material frame body 1. On this basis, in order to further improve the stability of the use state of the rocker 3 in the material cavity 11, in an optional implementation, two limit members 6 are also sleeved on the rocker 3, one end of the limit member 6 is fixed on the cavity wall of the material cavity 11 in the length direction, and the other end of the limit member 6 is formed with a limit hole for rotational matching with the rocker 3. Based on this structure, for each rocker 3, it has four supporting matching points relative to the material frame body 1.

[0043] Based on the above structure, in combination with the attached drawings, an optional implementation is given as an example, the power structure includes a pair of toggle blocks 71 respectively used to toggle a pair of rocker linkage blocks 5, a pair of pressure rods 72 connected one-to-one with the pair of toggle blocks 71, and a force rod 73 connected to the pair of pressure rods 72 at the same time; wherein each pressure rod 72 is also sleeved with an elastic member 74. The installation position of the force rod 73 on the pressure rod 72 is fixed, and two positioning nuts 75 can be set on the pressure rod 72, which are respectively used to limit the upper and lower ends of the force rod 73, so that there is no relative movement between the force rod 73 and the pressure rod 72. Under this structure, by applying pressure to the force rod 73, the pressure rod 72 and the toggle block 71 are moved along the force direction, so that the toggle block 71 can generate a toggle force for the rocker linkage block 5, so that the rocker linkage block 5 can drive the rocker 3 to rotate.

[0044] It should be noted that a pin 51 is provided on the rocker linkage block 5 and is used to match the toggle block 71, and a waist-shaped movable groove 711 is provided on the toggle block 71 and is used to match the pin 51. The waist-shaped movable groove can not only meet the rotation requirements of the rocker linkage block 5 relative to the outer wall of the material frame body 1, but also meet the movement requirements of the pressure rod 72 and the toggle block 71 under the action of the force rod 73.

[0045] On the basis of the above structure, a limiting guide assembly that matches a pair of pressure rods 72 in a one-to-one manner is further provided on the outer side wall of the material frame body 1; each limiting guide assembly includes at least one limiting block 76, and the pressure rod 72 passes through the limiting block 76. In conjunction with the attached drawings, an example is given in which each limiting guide assembly includes two limiting blocks 76 arranged at intervals, and each pressure rod 72 simultaneously passes through the two limiting blocks 76 of each limiting guide assembly package. Here, the limiting guide assembly can limit the motion trajectory of the pressure rod 72 under the action of the force rod 73, ensuring that the rocker linkage block 5 is accurately moved under the motion trajectory of the pressure rod 72, thereby causing the pair of clamping rods 2 to open relatively.

[0046] In addition, it should be noted that the preferred elastic member 74 is a spring body; and the two ends of the spring body are limited between the limit block 76 adjacent to the force rod 73 and the force rod 73 among the two limit blocks 76; and a stopper 77 suitable for abutting and cooperating with the spring body is also provided on the pressure rod 72 and located between the force rod 73 and the spring body. In other words, the spring body is limited as a whole between a limit block 76 and the stopper 77. Under this structure, when the pressure rod 72 moves toward the side of the rocker linkage block 5 along with the force rod 73, the spring body is compressed and deformed. In this way, when the top thrust force on the force rod 73 disappears, under the reshaping action of the spring body, the pressure rod 72, the toggle block 71 and the rocker linkage block 5 can all be restored to the initial state, thereby causing the pair of clamping rods 2 to be relatively retracted.

[0047] Finally, it is necessary to explain that the power structure also includes a force-applying structure suitable for pressing the force-bearing rod 73. For the force-applying structure here, any mature technology in the prior art that can realize linear lifting drive can be selected, such as but not limited to a cylinder, and this embodiment does not make an absolute limitation on this.

[0048] In summary, for the silicon ingot material frame of the present embodiment, when the force-bearing rod 73 is not subjected to the pushing effect, the pair of clamping rods 2 are in a relatively retracted state to achieve the clamping of the silicon ingot. When the clamping of the silicon ingot needs to be released, the force-bearing rod 73 is pushed so that the force-bearing rod 73 is under force, and the pressure rod 72 and the toggle block 71 move to the side of the rocker linkage block 5. At this time, the rocker linkage block 5 rotates relative to the outer wall of the material frame body 1 under the action of the toggle block 71, so that the pair of rockers 3 rotate, and then the pair of clamping rods 2 make a circular motion around the rocker 3 and gradually open to release the clamping of the silicon ingot.
