[0045] See Figures 1-3 This embodiment provides a device for manufacturing single crystal furnace electrode insulating sheets, which can automatically complete the manufacturing of single crystal furnace electrode insulating sheets. Compared with manual manufacturing, both processing efficiency and processing quality are improved.

[0046] Specifically, in this embodiment, the single crystal furnace electrode insulating sheet manufacturing device includes a frame 1, a pressure plate 2, a first upper mold 3, and a receiving lower mold 4.

[0047] The pressure plate 2 is slidably mounted on the frame 1 in the vertical direction, and the pressure plate 2 can switch between the initial position, the pre-pressing position and the pressing position.

[0048] The first upper mold 3 is set on the pressure plate 2 and its lower end protrudes relative to the lower surface of the pressure plate 2.

[0049] The lower mold plate 4 is set on the frame 1 and located below the pressure plate 2. The lower mold plate 4 is provided with a first notch 41 that is opposite to the first upper mold 3.

[0050] In this embodiment, the single crystal furnace electrode insulating sheet manufacturing device places the material strip to be processed on the receiving lower template 4, with the center of the material strip and the center of the first notch 41 collinear. Then, the pressure plate 2 is controlled to move from the initial position to the pre-pressing position to press the material strip and prevent it from shifting. Subsequently, the pressure plate 2 is controlled to move to the lower pressing position, so that the pressure plate 2 drives the first upper mold 3 to continue pressing down. The first upper mold 3 completes the cutting of the material strip and processes it into a single crystal furnace electrode insulating sheet. The setting of the first notch 41 allows the excess material on the material strip to be fully removed when the first upper mold 3 presses down and cuts the material strip.

[0051] In this way, the production of single crystal furnace electrode insulating sheets is completed automatically by the single crystal furnace electrode insulating sheet production device, which has high processing efficiency and can be free from the influence of subjective factors of operators, thereby improving the product qualification rate.

[0052] Specifically, in this embodiment, the frame 1 includes a top plate 11 and a guide column 13.

[0053] The base plate 12 and the top plate 11 are spaced apart vertically. The guide column 13 is set vertically, with its upper end fixed to the top plate 11 and its lower end fixed to the base plate 12. The lower template 4 is located above the base plate 12 and fixed to the guide column 13. The pressure plate 2 is located below the top plate 11 and is slidably connected to the guide column 13.

[0054] Optionally, the number of guide posts 13 is four, and the four guide posts 13 are distributed at the four corners of a rectangle.

[0055] Specifically, the pressure plate 2 is slidably installed through the guide column 13 in the vertical direction, and the guide column 13 guides the sliding of the pressure plate 2 to prevent the pressure plate 2 from deviating during the movement.

[0056] Furthermore, in this embodiment, in order to drive the pressure plate 2 to reciprocate in the vertical direction, the single crystal furnace electrode insulating sheet manufacturing device also includes a pressure plate driving component 5, which is disposed on the frame 1 and the output end of the pressure plate driving component 5 is connected to the pressure plate 2.

[0057] Optionally, the pressure plate drive 5 can be a cylinder. The cylinder body of the pressure plate drive 5 is fixedly mounted on the top plate 11 of the frame 1. The free end of the cylinder output rod of the pressure plate drive 5 is connected to the pressure plate 2, driving the pressure plate 2 to move up and down.

[0058] Furthermore, in this embodiment, the single crystal furnace electrode insulating sheet manufacturing device also includes a second upper mold 7. The pressure plate 2 is provided with a second upper mold through hole. The second upper mold 7 is disposed on the pressure plate 2 and its lower end extends into the second upper mold through hole. The lower surface of the second upper mold 7 and the side wall of the second upper mold through hole form a leveling space 71.

[0059] After the first upper mold 3 completes the cutting of the material strip and processes it into a single crystal furnace electrode insulating sheet, the pressure plate drive 5 drives the pressure plate 2 to move upward. Then, the operator transfers the single crystal furnace electrode insulating sheet to the bottom of the second upper mold 7, and the pressure plate drive 5 drives the pressure plate 2 to move downward, so that the second upper mold 7 moves downward until the single crystal furnace electrode insulating sheet is placed in the leveling space 71, and the processed single crystal furnace electrode insulating sheet is leveled.

[0060] Further optionally, a waste recycling bin 121 is provided on the rack 1; and / or

[0061] An insulating sheet collection groove 122 is provided on the frame 1.

[0062] The waste recycling bin 121 can collect the waste material cut off from the first upper mold 3; the insulating sheet collection groove 122 can level the single crystal furnace electrode insulating sheet after processing and leveling.

[0063] Specifically, in this embodiment, a waste recycling bin 121 is provided on the frame 1, and the first notch 41 is connected to the waste recycling bin 121. With this configuration, the waste material cut from the first upper mold 3 can fall directly into the waste recycling bin 121 through the first notch 41, eliminating the need for operators to manually collect the waste material and improving production efficiency.

[0064] Optionally, in order to reduce the noise generated when waste falls into the waste recycling bin 121, a first guide ramp 1211 is provided in the waste recycling bin 121. The first guide ramp 1211 and the first notch 41 are inclined downwards. The waste falling from the first notch 41 will first contact the first guide ramp 1211, and then move along the first guide ramp 1211 to the bottom of the waste recycling bin 121 under its own gravity.

[0065] Specifically, the waste recycling bin 121 is located between the lower template 4 and the base plate 12.

[0066] Meanwhile, in this embodiment, the frame 1 is provided with an insulating sheet collection groove 122, and the lower template 4 is provided with a second notch 42 that communicates with the insulating sheet collection groove 122. With this configuration, the finished and leveled single crystal furnace electrode insulating sheet can fall into the insulating sheet collection groove 122 through the second notch 42, thus completing the collection of the product.

[0067] It can be understood that the second notch 42 and the second upper mold 7 are not centered, but need to be staggered to prevent the electrode insulating sheet from falling into the second notch 42 when the second upper mold 7 is leveling the single crystal furnace electrode insulating sheet.

[0068] After the second upper mold 7 completes the leveling of the single crystal furnace electrode insulating sheet, the operator moves the single crystal furnace electrode insulating sheet, causing it to fall from the second notch 42 into the insulating sheet collection groove 122.

[0069] Furthermore, in order to protect the insulating sheet of the single crystal furnace electrode, in this embodiment, a second guide slope 1221 is provided in the insulating sheet collection groove 122. The second guide slope 1221 is arranged opposite to the second notch 42 and extends downward at an inclination. The single crystal furnace electrode insulating sheet falling from the second notch 42 will first contact the second guide slope 1221, and then slide down the second guide slope 1221 to the bottom of the insulating sheet collection groove 122 under its own gravity.

[0070] Specifically, the insulating sheet collection groove 122 is located between the lower template 4 and the base plate 12.

[0071] Furthermore, in this embodiment, in order to buffer the downward movement of the pressure plate 2 when it descends to press the material strip, and to prevent the material strip from being deformed due to excessive downward force, the single crystal furnace electrode insulating sheet manufacturing device also includes a buffer adjustment component 6. The buffer adjustment component 6 is slidably disposed on the frame 1 in the vertical direction, and the buffer adjustment component 6 is connected to the pressure plate 2 and can move synchronously with the pressure plate 2. The buffer adjustment component 6 can buffer the downward movement of the pressure plate 2.

[0072] Optionally, in this embodiment, the buffer adjustment assembly 6 includes a pre-compression mounting plate 61 and a pre-compression cylinder 62.

[0073] The pre-compression mounting plate 61 is slidably mounted on the frame 1 in the vertical direction. The output end of the pressure plate drive component 5 is fixedly connected to the pre-compression mounting plate 61.

[0074] Specifically, the pre-compression mounting plate 61 is slidably installed through the guide column 13 in the vertical direction. The guide column 13 guides the sliding of the pre-compression mounting plate 61 to prevent the pre-compression mounting plate 61 from deviating during the sliding process.

[0075] The pre-compression cylinder body of the pre-compression cylinder 62 is fixedly installed on the pre-compression component mounting plate 61, and the lower end of the pre-compression cylinder push rod of the pre-compression cylinder 62 is fixedly connected to the pressure plate 2.

[0076] When the cylinder output rod of the pressure plate drive 5 drives the pressure plate 2 to move from top to bottom to press the material belt, the pre-press cylinder 62 can buffer the downward movement of the pressure plate 2 to prevent the pressure plate 2 from moving too fast or the downward pressure from being too great.

[0077] Alternatively, the number of pre-compression cylinders 62 is at least four, and the pre-compression cylinders 62 are respectively distributed at least at the four corners of the pre-compression mounting plate 61.

[0078] Specifically, in this embodiment, there are four pre-compression cylinders 62, which are distributed at the four corners of the pre-compression mounting plate 61.

[0079] Specifically, the pressure of the pre-compression cylinder 62 is adjustable.

[0080] More specifically, in this embodiment, the pressure adjustment range of the pre-compression cylinder 62 is 0MPa-0.6MPa. The total pressure applied by the four pre-compression cylinders 62 ranges from 0kg to 120kg.

[0081] Of course, in other embodiments, the pressure adjustable range of the pre-compression cylinder 62 can also be set to other values ​​as needed.

[0082] Of course, in other embodiments, the structure of the buffer adjustment component 6 can also be selected as other, such as replacing the pre-compression cylinder 62 with a compression spring. The buffer adjustment component 6 includes a pre-compression mounting plate 61 and a compression spring, and the output end of the pressure plate drive component 5 is fixedly connected to the pre-compression mounting plate 61. The upper end of the compression spring is fixedly connected to the pre-compression mounting plate 61, and the lower end of the compression spring is fixedly connected to the pressure plate 2.

[0083] For example, in this embodiment, the overall workflow of the single crystal furnace electrode insulating sheet fabrication apparatus is as follows:

[0084] The pressure plate drive component 5 drives the pre-pressing component mounting plate 61 and the pressure plate 2 to move down synchronously, pressing the material strip to be processed on the receiving template 4; during this process, the buffer adjustment component 6 buffers the downward movement of the pressure plate 2 to avoid excessive downward pressure on the pressure plate 2;

[0085] After the strip is compressed, the pressure plate drive 5 further drives the pre-compression mounting plate 61 and the pressure plate 2 to move down synchronously, and the first upper die 3 completes the cutting of the strip. The waste material cut off by the first upper die 3 falls into the waste recycling bin 121 through the first notch 41.

[0086] The pressure plate drive 5 drives the pre-pressing component mounting plate 61 and the pressure plate 2 to move upward synchronously. The operator moves the pre-processed single crystal furnace electrode insulating sheet to the bottom of the second upper mold 7. Then, the pressure plate drive 5 drives the pre-pressing component mounting plate 61 and the pressure plate 2 to move downward synchronously, so that the second upper mold 7 moves down to place the single crystal furnace electrode insulating sheet in the leveling space 71, and levels the processed single crystal furnace electrode insulating sheet.

[0087] The pressure plate drive 5 drives the pre-pressing mounting plate 61 and the pressure plate 2 to move upward synchronously. The operator moves the leveled single crystal furnace electrode insulating sheet to the second notch 42. The leveled single crystal furnace electrode insulating sheet falls into the insulating sheet collection groove 122 through the second notch 42.

[0088] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
