[0044] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] like Figure 1 As shown, at least one embodiment provides a silicon ingot pressing material basket, including: a rectangular material frame 100, in which a silicon ingot accommodating space 101 is provided; and a holding mechanism 200, which includes a pair of clamping parts 210 and at least one lifting mechanism 300; wherein the clamping part 210 is arranged in the material frame 100 and parallel to the length direction of the rectangular material frame 120, and is driven by the lifting mechanism 300 to perform a clamping action on the silicon ingot located in the accommodating space 101. The clamping part 210 is driven by the lifting mechanism 300 to realize automatic clamping and release of the silicon ingot, and its automated clamping control helps to improve the stability of the silicon ingot during the processing process and realize the automation of the entire production process.

[0046] In some embodiments, the lifting mechanism 300 moves on the rectangular material frame 100 according to the weight of the silicon ingot, and the manipulator adjusts the hanging shaft 103 to control the placement of the silicon ingot in the rectangular material frame 100, so that the lifting mechanism 300 is linked with the weight of the silicon ingot in the loading frame 110; specifically, the rectangular material frame 100 includes a stacked loading frame 110 and a unloading frame 120, and the two cross bars 111 of the loading frame 110 are provided with silicon ingot positioning ports 102 on the inner side of the frame to place the silicon ingot, and the loading frame 110 is provided with a hanging shaft 103; wherein the hanging shaft 103 drives the silicon ingot in the loading frame 110 to rise and fall in the accommodating space 101, so that the lifting mechanism 300 synchronously produces up and down displacement, and the hanging shaft 103 provided in the loading frame 110 can cooperate with a lifting machinery or an automatic lifting mechanism to realize the automatic transportation of silicon ingots.

[0047] like Figure 2 As shown, in order to make the lifting mechanism 300 and the clamping part 210 cooperate with each other and move synchronously, so as to control the tightness of the clamping part 210 on the silicon ingot by the lifting and lowering of the lifting mechanism 300, the lifting mechanism 300 includes a sliding member 310 and a lifting rod 320; the sliding member 310 is connected to the cross bar 111, the lifting rod 320 is connected to the unloading frame 120, and the lifting rod 320 is connected to the sliding member 310 through an elastic member; according to the rise and fall of the loading frame 110, the lifting rod 320 is moved in the vertical direction of the sliding member 310 to adjust the clamping action of the clamping part 210.

[0048] like Figure 3 and Figure 4 As shown, when the silicon ingot and the loading frame 110 are placed on the unloading frame 210, the weight of the silicon ingot causes the lifting rod 320 to move downward (i.e., move in the G direction) to press the sliding member 310, thereby causing the entire lifting mechanism 300 to move downward and drive each clamping part 210 to move closer to each other in the F direction to form a clamp; when the silicon ingot is removed from the loading frame, the elastic part of the lifting mechanism 300 lacks the pressure of the weight of the silicon ingot, and the lifting rod 320 moves upward to relax the clamping part 210.

[0049] At some force values, when the lifting rod 320 rises or falls, the clamping part 210 moves with it through the traction of the swing assembly 301, thereby performing the action of clamping or releasing the silicon ingot. The lifting rod 320 is connected with the swing assembly 301, and the swing assembly 301 includes: a mounting seat 311 and two swing arms 321; the mounting seat 311 is sleeved on the lifting rod 320, and its two sides are respectively hinged to one end of the corresponding swing arm 321, and the clamping part 210 passes through the blanking frame 120 and is hinged to the other end of the swing arm 321; the mounting seat 311 moves with the lifting rod 320 to pull the swing arm 321, and pulls the clamping part 210 to perform the clamping action; specifically, When the silicon ingot pressing frame is in a relaxed state, its upper and lower frames are in a separated state. When the silicon ingot is placed on the upper frame 110, the mounting seat 311 is driven downward by the lifting rod 320, and the two swing arm members 321 connected to the mounting seat 311 pull the two clamping parts 210 to clamp until the silicon ingot pressing frame is in a clamped state. The automated clamping and releasing action of the lifting rod 320 can speed up the production process, reduce the need for manual direct handling of silicon ingots, and improve production efficiency.

[0050] In some embodiments, in order to provide a stable clamping structure, the clamping portion 210 includes a clamping rod 211 and a support plate 212; the two ends of the clamping rod 211 are respectively connected to the support plates 212, the support plates 212 are arranged in the blanking frame 120 and are hinged to the swing arm 321 through the clamping rod 211, and the swing arm 321 drives the support plate 212 to move so that the clamping rod 211 clamps the silicon ingot. The clamping rod 211 is made of a flexible material, and at least two are provided to provide a stable clamping force. The swing arm 321 drives the support plate 212 to move through the hinge point, effectively transmits power, and accurately controls the opening and closing action of the clamping rod 211.

[0051] In some embodiments, a swing arm shaft 232 is provided in the unloading frame 120, and both ends of the swing arm shaft 232 are respectively connected to the support plate 212, and one end of the swing arm shaft 232 extends from the unloading frame 120 and is hinged to the swing arm member 321; the swing arm member 321 drives the swing arm shaft 232 to rotate, so that the clamping part 210 produces a clamping action. In order to improve the stability and rigidity of the swing arm 321 and reduce the bending or deformation during the clamping process, the swing arm 321 includes: a first swing arm plate 321a and a second swing arm plate 321b; one end of the first swing arm plate 321a forms a pivot structure with the second swing arm plate 321b through a hinge shaft 321c, the other end of the first swing arm plate 321a is hinged to the mounting seat 311, and the other end of the second swing arm plate 321b is hinged to the swing arm shaft 232; the first swing arm plate 321a is pulled by force to cause the second swing arm plate 321b to rotate relative to the clamping portion 210. The pivot structure of the swing arm 321 causes the first swing arm plate 321a and the second swing arm plate 321b to rotate relative to each other, and then converts into the movement required by the clamping portion 210. The hinge point formed by the hinge shaft 321c can reduce friction and wear during rotation and extend the service life of the swing arm 321.

[0052] like Figure 5 As shown, in some embodiments, in order to enhance the stability of the entire swing arm system and ensure that the swing arm shaft 232 operates accurately in a fixed position, the bottom of the blanking frame 120 is connected to a bearing seat 121, and the swing arm shaft 232 is sleeved and connected in the bearing seat 121. The bearing seat 121 provides support for the swing arm shaft 232, and the bearing structure can significantly reduce the friction of the swing arm shaft during movement.

[0053] In some embodiments, when the hanging shaft 103 places the loading frame 110, in order to ensure that the loading frame and the unloading frame are accurately aligned, at least one pair of positioning parts are passed between the ends of the corresponding support frames of the loading frame 110 and the unloading frame 120; the pair of positioning parts include: a transverse protrusion block 112, a longitudinal protrusion block 122, and a transverse card interface and a longitudinal card interface; wherein the loading frame 110 and the unloading frame 120 are connected through the positioning parts, that is, the transverse protrusion block 112 is adapted to the transverse card interface, and the longitudinal protrusion block 122 is adapted to the longitudinal card interface, and the design of the positioning parts can realize the precise positioning and quick connection of the loading frame and the unloading frame, thereby improving the production efficiency and the convenience of operation.

[0054] In some embodiments, a bottom roller 123 is disposed at the bottom of the blanking frame 120. The bottom roller 123 is made of silicone material and at least two are disposed. The bottom roller 123 is made of silicone material and is soft, which can reduce damage to the surface of the silicon ingot and protect the silicon ingot from scratches or wear.

[0055] To summarize, the silicon ingot clamping basket has a accommodating space for silicon ingots in its rectangular frame. The lifting mechanism and the holding part in the holding mechanism cooperate with each other, so that the lifting mechanism controls the clamping part to clamp and release the accommodating space to provide a consistent clamping force and enhance the precise control of the clamping space. The clamping part is driven by the lifting mechanism to realize automatic clamping and releasing of the silicon ingot. The automated clamping control helps to improve the stability of the silicon ingot during the processing and realize the automation of the entire production process.
