Description

Technical Field

[0001] The invention relates to the technical field of mechanical grippers, and in particular to a silicon material feeding mechanical gripper. Background Art

[0002] Silicon material, as the essence obtained from high-temperature smelting of silica, occupies a pivotal position in many industrial fields with its high purity, excellent high-temperature resistance and excellent electrical properties. There are many types of silicon material, including but not limited to ordinary silicon material, diamond silicon material, quartz silicon material, silicon oxide (silicon dioxide), polycrystalline silicon, single crystal silicon, silicon nitride, aluminum oxide silicon, calcium silicon and ferrosilicon, etc. Each type of silicon material plays an irreplaceable role in key fields such as semiconductors, photovoltaics, and electronic devices due to its unique composition, structure and performance.

[0003] In the production and processing of silicon materials, in order to ensure that they reach the ideal purity and quality, a crucial step is to accurately put the silicon materials into the furnace for high-temperature melting treatment. In this process, traditional mechanical grippers often directly flip the box loaded with silicon materials when feeding.

[0004] Although the existing clamps are easy to operate, they have significant disadvantages: the silicon material lacks effective and uniform discharge control during free fall, resulting in uneven accumulation of the silicon material in the crucible, and "hot spots" may form in some areas, which prolongs the overall heating and melting time and reduces production efficiency; at the same time, the rapid unloading of a large amount of concentrated silicon material may also cause drastic fluctuations in the level of the silicon material solution. The drastic fluctuations in the level may cause uneven distribution of impurities in the silicon material solution, thereby affecting the purity of the final silicon material, and the drastic fluctuations in the level of the silicon material solution may cause uneven stress distribution during crystal growth, thereby increasing the probability of dislocation formation. The drastic fluctuations in the level of the silicon material solution may also cause instability in the crystal growth process, thereby reducing the crystallization rate and reducing product quality. Summary of the invention

[0025] As a further description of the above technical solution:

[0026] The driving mechanism includes a servo motor installed on one side of the mounting frame, the output end of the servo motor is connected to a main pulley, a transmission shaft is installed on one side of the support frame, one side of the transmission shaft passes through the connecting frame and is connected to a secondary pulley, and the main pulley and the secondary pulley are connected by a belt.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] During the silicon material feeding process, a mechanism is designed to ensure the uniformity, controllability and accuracy of feeding. When the loading box rotates with the servo motor to discharge the material, the rotating motor starts synchronously to drive the rotating shaft, the connecting cylinder and the tilting plate to rotate. The abutment rod is close to the tilting plate under the action of the compression spring and slides with its rotation. The sliding sleeve rod drives the discharge plate to move back and forth left and right, so that the silicon material is evenly dispersed and dropped, avoiding the problem of uneven feeding caused by accumulation at a single position, and ensuring the stability of the silicon material solution level.

[0029] In order to finely adjust the uniformity of feeding, the introduction of the first electric push rod realizes the dynamic adjustment of the tilt angle of the tilt plate. As the first electric push rod extends, the moving plate pushes the tilt plate to rotate around the positioning column, thereby changing the swing amplitude of the discharge plate. In particular, when the tilt plate is close to vertical, the discharge plate stops swinging, realizing centralized feeding, which improves the flexibility and accuracy of feeding.

[0030] In addition, the first electric push rod also links the movement of the first closing plate and the second closing plate through gear transmission, dynamically adjusts the opening quantity of the discharge port, and accurately controls the discharge amount and feeding rate of silicon materials according to demand. This design not only enhances the adaptability and operability of the equipment, but also realizes the precise discharge control of quantitative silicon materials.

[0031] In order to solve the problem of silicon material accumulation after the loading box is inverted, an anti-accumulation mechanism based on a transmission wheel, a shaking block and an electric roller is designed. When the rotating shaft rotates, the transmission belt drives the transmission wheel on the outer periphery of the rotating rod to rotate, thereby driving the mounting rod to rotate and pulling the shaking block. The rotation of the shaking block is combined with the rolling of the electric roller, which effectively promotes the movement of the silicon material to the discharge port. At the same time, the extension and retraction of the second electric push rod adjusts the fluctuation amplitude of the shaking block, further enhancing the control over the silicon material discharge process, ensuring the smooth discharge of the silicon material after the loading box is inverted, and effectively preventing accumulation.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] like Figure 1-Figure 11 As shown, a silicon material feeding mechanical gripper provided by the present invention comprises a frame 10, the frame 10 comprises a mounting frame 11 mounted on a mechanical arm by fixing screws, the mounting frame 11 is connected to a support frame 13 through two inner connecting frames 12, the support frame 13 is provided with a loading box 15 through a limiting frame 14, and further comprises: a driving mechanism 20 assembled on one side of the mounting frame 11, the driving mechanism 20 comprises a servo motor 21 mounted on one side of the mounting frame 11, the output end of the servo motor 21 is connected to a main pulley 22, a transmission shaft 25 is mounted on one side of the support frame 13, one side of the transmission shaft 25 passes through the connecting frame 12 and is connected to a secondary pulley 23, and the main pulley 22 and the secondary pulley 23 are connected by a belt 24;

[0052] In the silicon material feeding process, the first step is to place the loading box 15 loaded with silicon materials on the limiting frame 14 inside the support frame 13. This operation must strictly follow the guidance of the limiting plate on the inner wall of the support frame 13 to ensure that the loading box 15 is stably in place. Then, the flexible movement characteristics of the fixing component 30 are used to firmly fix and limit the loading box 15 to ensure the smooth progress of subsequent operations.

[0053] After the fixing work is completed, the robot arm starts and drives the loading box 15 to move it smoothly to the top of the furnace. At this time, by controlling the start of the servo motor 21, the main pulley 22 starts to rotate, and its rotational power is effectively transmitted to the secondary pulley 23 through the belt 24, which is a transmission element, so that the two rotate synchronously;

[0054] As the secondary pulley 23 rotates, the transmission shaft 25, as the core component for connecting and transmitting power, also begins to rotate, eventually driving the support frame 13 to rotate as a whole, thereby driving the loading box 15 and the silicon material inside it to slowly tilt, so that the silicon material can be accurately placed into the furnace.

[0055] like Figure 1 , Figure 3 , Figure 4 As shown, a fixing assembly 30 is installed on both sides of the support frame 13, and the fixing assembly 30 includes an electric telescopic device 31 installed on both sides of the support frame 13 and a placement plate 35 connected between the two limit frames 14. The tops of the two electric telescopic devices 31 are connected to a lower pressing plate 32, and the two lower pressing plates 32 are connected to both sides of the closed cover 33. The bottom of the closed cover 33 is installed with an abutment member, and the abutment member includes a lower pressing block 34 installed at the bottom of the closed cover 33. The top of the placement plate 35 is fixedly connected to two fixing blocks 351, and the two fixing blocks 351 are connected by The fixing column 352 is connected, and the outer periphery of the fixing column 352 is rotatably connected with a contact block 353 that is engaged with the downward pressing block 34. The top of the placing plate 35 is fixedly connected with a welding block 354. The inside of the welding block 354 is slidably connected with a push rod 355. One side of the push rod 355 is in contact with the contact block 353, and the side of the push rod 355 away from the contact block 353 is connected with a block 356. The outer periphery of the push rod 355 is sleeved with a telescopic spring 357, and the two ends of the telescopic spring 357 are respectively connected with one side of the welding block 354 and one side of the block 356;

[0056] During the fixing process of the loading box 15, the electric telescopic devices 31 disposed on both sides of the support frame 13 are first started to slowly descend, and this action drives the lower pressing plate 32 and the closing cover 33 connected to the electric telescopic devices 31 to move downward synchronously until the closing cover 33 is tightly fitted to the upper surface of the loading box 15, thereby closing and fixing the top thereof. At the same time, the pressing block 34 connected to the bottom of the closing cover 33 also moves downward accordingly, and when it contacts the inner groove of the contact block 353, the continued pressing action will cause the contact block 353 to rotate around the fixing column 352 as the center;

[0057] During the rotation of the contact block 353, the push rod 355 inside the welding block 354 is abutted and moves inside the welding block 354, and this movement in turn drives the abutment block 356 to move toward one side of the loading box 15, and at the same time stretches the telescopic spring 357 connected thereto. As the closing cover 33 completely fits the top of the loading box 15, not only the top of the loading box 15 is fixed and closed, but also the loading box 15 is firmly pushed toward the limiting frame 14 through the action of the abutment block 356, achieving all-round fixation of the loading box 15 on all sides.

[0058] When the feeding is completed and the loading box 15 needs to be removed, the electric telescopic device 31 is operated again to extend it in the opposite direction, thereby driving the closing cover 33 and the lower pressure plate 32 to rise. During this process, the lower pressure block 34 also rises accordingly, releasing the abutment against the contact block 353. At this time, the telescopic spring 357 uses its rebound energy to push the push rod 355 to reset, thereby driving the abutment block 356 away from the loading box 15, so that the push rod 355 is again tightly attached to the contact block 353. At this point, the fixed and closed state of the loading box 15 is released, and it can be safely and conveniently removed for subsequent processing.

[0059] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10As shown, the inside of the closing cover 33 is connected with a discharge assembly 40 and an adjustment assembly 50, and a groove 331 and an inner groove 332 are provided inside the closing cover 33. The discharge assembly 40 includes a power source installed on one side of the closing cover 33, and the power source includes a rotating motor 41 installed on one side of the closing cover 33. The output shaft of the rotating motor 41 passes through the inner groove 332 and is connected to a rotating shaft 42. The side of the rotating shaft 42 away from the rotating motor 41 passes through the closing cover 33 and is connected to a connecting cylinder 43. The inclined surface of the connecting cylinder 43 is connected to an inclined plate 44. The groove 331 is A fixed rod 45 is fixedly connected to the inner wall, a sliding sleeve rod 46 is slidably connected to the outer periphery of the fixed rod 45, a side of the sliding sleeve rod 46 away from the fixed rod 45 is fixedly connected to an abutting rod 47 abutting against the inclined plate 44, a compression spring 48 is sleeved on the outer periphery of the fixed rod 45, a discharge plate 49 is fixedly connected between the inner walls of the groove 331, a discharge plate 491 is fixedly connected to the outer periphery of the sliding sleeve rod 46, a lower surface of the discharge plate 491 is connected to a plurality of diverter plates 492, and a side surface of the discharge plate 49 and the discharge plate 491 are both provided with a plurality of discharge ports 493;

[0060] When the loading box 15 is rotated and unloaded by the servo motor 21, the rotating motor 41 is started, and the rotating shaft 42 is driven to rotate, thereby driving the connecting cylinder 43 and the inclined plate 44 connected thereto to rotate synchronously. Since the abutment rod 47 is always in close contact with the edge surface of the inclined plate 44 under the strong rebound effect of the compression spring 48, when the inclined plate 44 rotates, the abutment rod 47 will slide along different inclined points on the inclined plate 44 for contact;

[0061] This sliding process is transmitted by the sliding sleeve rod 46, driving the discharge plate 491 to reciprocate in the left and right directions. During this process, the silicon material will first flow out along the discharge port 493 of the discharge plate 49 and fall on the continuously shaking discharge plate 491. Due to the left and right shaking of the discharge plate 491, the silicon material falling on it is affected by this dynamic force and will be dispersed and fall along the preset multiple diverter plates 492;

[0062] This design not only cleverly avoids the problem of uneven material discharge caused by the accumulation of silicon materials in a single location, but also allows the silicon materials to fall evenly and stably along different paths through the guidance of the diverter plate 492. It also effectively prevents large fluctuations in the level of the silicon material solution caused by concentrated falling, ensuring the smoothness and efficiency of the entire material discharge process.

[0063] like Figure 1 , Figure 5 , Figure 7 , Figure 8As shown, the adjustment component 50 includes a pusher installed on one side of the groove 331, and a hinge installed inside the connecting tube 43, the pusher includes a recessed groove 51 opened on the inner side of the groove 331, two first electric push rods 52 are installed inside the recessed groove 51, one side of the two first electric push rods 52 are connected with a moving plate 53, the moving plate 53 contacts with the inclined plate 44 and slides on the outer periphery of the connecting tube 43, the hinge includes a connecting frame 54 installed on the inner wall of the connecting tube 43, a positioning column 541 is fixedly connected between the inner walls of the connecting frame 54, a rotating sleeve 542 is rotatably connected to the outer periphery of the positioning column 541, the rotating sleeve 542 is fixedly connected to the inclined plate 44, and one side of the inclined plate 44 is connected to the connecting tube 43 through a tension spring 543;

[0064] In order to flexibly adjust the amplitude of the left-right swing of the discharge plate 491 and thus control the uniformity of the feeding, when the first electric push rod 52 is started to extend, it will push the moving plate 53 to move along the outer circumference of the connecting tube 43. As the moving plate 53 gradually moves, it will come into contact with the extended portion of the inclined plate 44 and continue to push the inclined plate 44.

[0065] This pushing action will cause the rotating sleeve 542 connected to the inclined plate 44 to rotate with the positioning column 541 as the rotation center, and the tension spring 543 will also be stretched accordingly. It is worth noting that as the inclination angle of the inclined plate 44 gradually increases, that is, it gets closer to the vertical state, under the action of the continuous contact between the abutment rod 47 and the inclined plate 44, the left and right shaking amplitude of the discharge plate 491 will be reduced accordingly, thereby achieving fine adjustment of the uniformity of feeding;

[0066] On the other hand, when it is necessary to feed the silicon materials in a centralized manner, this can be achieved by further adjusting the inclination angle of the inclined plate 44. Specifically, the movable plate 53 is continued to be pushed until the inclined plate 44 is pushed to a vertical position. At this time, due to the change in the rotation angle of the inclined plate 44, the discharge plate 491 will no longer swing left and right, but allow the silicon materials to slide out smoothly along the discharge port 493, thereby achieving the effect of centralized feeding. This design not only improves the flexibility of feeding, but also ensures the controllability and accuracy of the feeding process.

[0067] like Figure 8As shown, the adjustment assembly 50 also includes a closing member connected to the outer periphery of the moving plate 53, and the closing member includes a first closing plate 551 and a second closing plate 557 which are slidably connected to the inside of the discharge plate 49 through a slide groove 494, and a first connecting plate 55 and a second connecting plate 556 which are slidably connected to the inside of the discharge plate 49 through a push groove 495. The first closing plate 551 is connected to the first connecting plate 55, and the second closing plate 557 is connected to the second connecting plate 556. The outer periphery of the moving plate 53 is fixedly connected to a first gear plate 552, and one side of the second connecting plate 556 is connected to a second gear plate 555. A positioning rod 553 is installed on one side of the discharge plate 49, and the outer periphery of the positioning rod 553 is rotatably connected to a rotating gear 554 which meshes with the first gear plate 552 and the second gear plate 555.

[0068] Driven by the first electric push rod 52, the moving plate 53 not only moves along the outer circumference of the connecting tube 43, but also, as the moving plate 53 moves, the first connecting plate 55 is pulled, thereby pulling the first closing plate 551 to move accordingly. During this process, the first gear plate 552 moves synchronously with the moving plate 53, and the first gear plate 552 drives the rotating gear 554 to rotate smoothly along the outer circumference of the positioning rod 553.

[0069] The rotation of the rotating gear 554 further triggers the synchronous movement of the second gear plate 555 meshing therewith. The movement of the second gear plate 555 is then transmitted through the second connecting plate 556, pulling the second closing plate 557 to slide in the preset slide groove 494. While reducing the left-right swing amplitude of the discharge plate 491, it also realizes the dynamic adjustment of the opening number of the discharge ports 493 on the discharge plate 49. Since the discharge amount of silicon material is reduced, reducing the left-right swing amplitude of the discharge plate 491 will not affect the uniform feeding of a small amount of silicon material.

[0070] In this way, we can flexibly adjust the discharge amount and feeding rate of silicon material according to actual needs by accurately controlling the moving distance of the moving plate 53, so as to achieve precise discharge control of different quantitative silicon materials. This design not only improves the accuracy and flexibility of feeding, but also significantly enhances the adaptability and operability of the equipment.

A second electric push rod 64 is installed between the slide plate 63 and the discharge plate 49. A rotating column 65 is rotatably connected inside the slide plate 63. The slide plate 63 is extended from both sides of the rotating column 65 and connected to a shaking block 66. A plurality of electric rollers 67 are installed between the two shaking blocks 66. A moving groove 661 is provided on one side of the shaking block 66 close to the rotating rod 61. The inner wall of the moving groove 661 is slidably connected to the mounting rod 613. A mounting plate 68 is installed on one side of the discharge plate 49. The mounting plate 68 is arranged above the second electric push rod 64 to prevent the silicon material from damaging the second electric push rod 64.

[0072] In order to prevent the silicon material from piling up on the top of the closing cover 33 after the loading box 15 is inverted, thereby affecting the normal discharge amount of the silicon material, when the rotating shaft 42 starts to rotate, it will synchronously drive the transmission wheel 611 to rotate. This rotation is transmitted by the transmission belt 612, further driving the transmission wheel 611 on the outer periphery of the rotating rod 61 to rotate synchronously.

[0073] As the transmission wheel 611 on the outer periphery of the rotating rod 61 continues to rotate, the mounting rod 613 is driven to rotate. During the rotation process, the mounting rod 613 moves along the moving groove 661 provided on the side of the shaking block 66. This movement process generates a pulling force on the shaking block 66, thereby causing the rotating column 65 connected to the shaking block 66 to rotate inside the slide plate 63. This rotation action causes the silicon material accumulated on the electric roller 67 to be pushed toward the discharge port 493.

[0074] At the same time, the continuous rolling of the electric roller 67 and the periodic shaking of the shaking block 66 cooperate with each other, significantly accelerating the speed of the silicon material moving to the discharge port 493. In order to further enhance the control of the silicon material discharge process, by controlling the extension and contraction of the second electric push rod 64, the slide plate 63 can be pulled to slide on the periphery of the two sliders 62. This sliding action will change the relative position between the shaking block 66 and the mounting rod 613, thereby realizing the precise adjustment of the fluctuation amplitude of the shaking block 66.

[0075] Specifically, when the second electric push rod 64 is extended longer, the fluctuation amplitude of the shaking block 66 will increase accordingly, which helps to disturb the silicon material more strongly and promote its flow to the discharge port 493; conversely, when the second electric push rod 64 is contracted shorter, the fluctuation amplitude of the shaking block 66 will decrease to adapt to different discharge requirements or slow down the flow speed of the silicon material. This design ensures the smooth discharge of the silicon material after the loading box 15 is inverted, and effectively prevents the occurrence of accumulation.

[0076] Working principle: First, place the loading box 15 loaded with silicon materials on the limiting frame 14 inside the support frame 13, and ensure that the loading box 15 is stably positioned under the guidance of the limiting plate on the inner wall of the support frame 13. Then, using the flexibility of the fixing assembly 30, start the electric telescopic device 31 to lower the lower pressure plate 32 and the closing cover 33, close and fix the top of the loading box 15, and at the same time, the pressing block 34 at the bottom of the closing cover 33 pushes the contact block 353 to rotate, and the pushing rod 355 in the welding block 354 cooperates with the block 356 to firmly push the loading box 15 to the limiting frame 14, so as to achieve all-round fixation.

[0077] After the fixation is completed, the robot arm smoothly moves the loading box 15 to the top of the furnace, drives the main pulley 22 to rotate through the servo motor 21, transmits power to the secondary pulley 23 through the belt 24, drives the transmission shaft 25 and the support frame 13 to rotate as a whole, so that the loading box 15 and the silicon material are slowly tilted, and the material is accurately fed into the furnace;

[0078] During the rotary unloading process, the rotating motor 41 drives the rotating shaft 42, the connecting tube 43 and the inclined plate 44 to rotate synchronously. The abutment rod 47 is tightly attached to the inclined plate 44 under the action of the compression spring 48 and slides with its rotation. The sliding sleeve rod 46 drives the discharge plate 491 to move back and forth left and right. The silicon material flows out from the discharge port 493 and falls on the shaking discharge plate 491, and is dispersed and falls through the diverter plate 492, which effectively avoids accumulation at a single position, ensures uniform unloading and stable horizontal surface of the silicon material solution in the melting furnace.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
