Description

Technical Field

[0001] This invention belongs to the field of acupuncture equipment technology, and particularly relates to a dual-station crucible support acupuncture device. Background Technology

[0002] With the rapid development of the domestic photovoltaic industry, the domestic demand for silicon concentrate has also increased. In recent years, industries such as aerospace and automobile manufacturing have had an urgent need for high-rigidity and lightweight crucibles. Carbon / carbon composite crucibles have a wide range of applications in melting metals, rare and precious metals and non-metals. However, the traditional crucible needle punching equipment operates in a single-station manner, resulting in low production efficiency.

[0003] For example, patent application number CN202010546987.2 describes a carbon fiber crucible needle-punching forming device, which includes a bottom needle-punching device, a side needle-punching device, a shaping support device, a moving support device, and an atomizing spray device. The bottom needle-punching device corresponds to the bottom position of the crucible preform and performs needle-punching forming treatment on the bottom of the crucible preform. The side needle-punching device corresponds to the side position of the crucible preform and performs needle-punching forming treatment on the side of the crucible preform. The shaping support device corresponds to the bottom needle punching device and the side needle punching device. The shaping support device supports the crucible preform. The side needle punching device and the shaping support device are located on the movable support device. The movable support device drives the side needle punching device and the shaping support device to adjust their positions. The atomizing spray device corresponds to the shaping support device. The atomizing spray device sprays liquid onto the crucible preform placed on the shaping support device. However, the disadvantage of this technical solution is that it is a single-station operation with low production efficiency. Summary of the Invention

[0009] Furthermore, the lifting device includes a gantry frame, which is fixed to the side of the bottom boss. The gantry frame is slidably connected to the crossbeam, and the crossbeam is slidably connected to the needle-punching device.

[0010] Furthermore, the acupuncture device includes a first acupuncture device and a second acupuncture device, both of which slide on the crossbeam.

[0011] Furthermore, a barrier is fixed around the bottom protrusion.

[0012] Furthermore, a function switching device is provided on the bottom protrusion. The function switching device includes a motor four, which is fixed on the side of the bottom protrusion away from the gantry frame. A four-bladed turntable is fixed at the output end of the motor four. A feeding device, a cleaning device, a detection device, and a material changing device are fixed around the four-bladed turntable. In the initial state, the feeding device is located above the crucible support device two.

[0013] Furthermore, the feeding device includes a feeding cylinder fixed on a four-leaf turntable. Multiple crucibles can be vertically placed inside the feeding cylinder. A cylinder is fixed on the four-leaf turntable, and the output end of the cylinder is connected to a movable frame. The movable frame is fixedly connected to an upper movable rod and a lower movable rod respectively. Both upper movable rods are rotatably connected to an upper baffle plate. The upper baffle plate is installed on a rotating column. All four rotating columns rotate on the four-leaf turntable. An upper nut is threadedly connected to the upper end of the rotating column. The upper nut fixes the upper baffle plate, the upper isolation block, and the upper baffle plate two to the upper end of the rotating column. A lower nut is threadedly connected to the lower end of the rotating column. The nut fixes the lower baffle plate, the lower isolation block, and the lower baffle plate two to the lower end of the rotating column. Both lower movable rods are rotatably connected to the lower baffle plate.

[0014] Furthermore, the cleaning device includes a cylinder two, which is fixed on a four-leaf turntable. The output end of cylinder two is rotatably connected to a rotating rod one.

The crucibles on the first workstation and above it are moved to the outside, and the needle-punched crucibles can be removed. The unpunched crucibles are placed on the first workstation to wait for needle-punching. Compared with the single-workstation needle-punching device, this scheme sets up two needle-punching workstations.

Detailed Implementation

[0030] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Example 1

[0033] like Figures 1-9As shown, a dual-station crucible holder needle punching device includes a first station and a second station. The first station and the second station are respectively installed at both ends of a turntable 8. The turntable 8 rotates on a fixed base. Its middle part is connected to the output end of a motor. The motor is installed at the lower end of the fixed base. A lifting device is fixed on the side of the fixed base. A needle punching device is installed on the lifting device. In the initial state, the first station is located below the needle punching device.

[0034] The working principle of the above technical solution is as follows: the crucible is placed on the first station, the carbon fiber sheet is placed on the crucible at the first station and simply fixed with nails. The position of the needle punching device can be adjusted by the lifting device. When the needle punching device is adjusted to the appropriate position and started, the needle punching device will needle the carbon fiber sheet into the inside of the crucible to enhance the crucible's toughness and prevent the crucible from cracking. The first station can be rotated on the turntable 8 to drive the crucible to rotate. The needle punching device can needle the upper surface of the crucible in all directions.

[0035] When the crucible at the first station is needled, other crucibles can be installed at the second station, and carbon fiber sheets can be fixed to the crucibles. After the crucible at the first station is needled, the turntable 8 can be rotated by motor 1 to move the crucibles at the second station and above to the bottom of the needled device, so that needled work can be performed immediately. The crucibles at the first station and above are moved to the outside, and the needled crucibles can be removed. The unneeded crucibles are placed at the first station to wait for needled work.

[0036] Compared to a single-station needle punching device, this solution sets up two needle punching stations. The two stations rotate 180 degrees and then exchange positions, improving needle punching and production efficiency.

[0037] Example 2

[0038] like Figures 1-9 As shown, the first station includes a second motor and a first crucible support device 10. The second motor is installed at the lower end of the turntable 8, and the output end of the second motor is connected to the first crucible support device 10. The first crucible support device 10 rotates on the upper end of the turntable 8.

[0039] The first station includes a second motor and a first crucible support device 10. The second motor is installed at the lower end of the turntable 8, and the output end of the second motor is connected to the first crucible support device 10. The first crucible support device 10 rotates on the upper end of the turntable 8.

[0040] The fixed base includes a bottom boss 1, a bracket 6 is fixed on the bottom boss 1, a turntable 8 rotates on the bracket 6, a motor is installed at the lower end of the bracket 6, and a lifting device is fixed on the side of the bottom boss 1.

[0041] The working principle of the above technical solution is as follows: When the first station is located below the needle-punching device, that is, when the crucible support device 10 is located below the needle-punching device, the second motor drives the crucible support device 10 to rotate on the turntable 8. The needle-punching device needles the upper surface of the crucible on the crucible support device 10. After the needle-punching is completed, the first motor is started, driving the turntable 8 to rotate 180 degrees on the support 6. When the second station is located below the needle-punching device, that is, when the second crucible support device 12 is located below the needle-punching device, the third motor is started, driving the second crucible support device 12 to rotate on the turntable 8. The needle-punching device needles the upper surface of the crucible on the crucible support device 10.

[0042] Example 3

[0043] like Figures 1-9 As shown, the lifting device includes a gantry frame 2, which is fixed to the side of the bottom boss 1. The gantry frame 2 is slidably connected to the cross frame 3, and the cross frame 3 is slidably connected to the needle-punching device.

[0044] The working principle of the above technical solution is as follows: the gantry frame 2 can control the horizontal frame 3 to move up and down on the gantry frame 2, and the horizontal frame 3 can drive the needle punching device to move left and right on the horizontal frame 3.

[0045] Example 4

[0046] like Figures 1-9 As shown, the acupuncture device includes a first acupuncture device 4 and a second acupuncture device 5, both of which slide on the crossbeam 3.

[0047] The working principle of the above technical solution is as follows: the two sets of needle-punching devices can quickly needle the crucible, and the needle-punching efficiency is high.

[0048] Example 5

[0049] like Figures 1-9 As shown, a barrier 13 is fixed around the bottom boss 1;

[0050] The working principle of the above technical solution is as follows: the enclosure 13 surrounds the equipment to prevent accidental contact and damage to the equipment and personnel.

[0051] Example 6

[0052] like Figures 1-9 As shown, the bottom boss 1 is provided with a function switching device. The function switching device includes a motor 14. The motor 14 is fixed on the side of the bottom boss 1 away from the gantry frame 2. A four-leaf turntable 15 is fixed at the output end of the motor 14. A feeding device 16, a cleaning device 17, a detection device 18 and a material changing device 19 are fixed around the four-leaf turntable 15 respectively. In the initial state, the feeding device 16 is located above the crucible support device 12.

[0053] The working principle of the above technical solution is as follows: When the first station is working, the second station is idle. The feeding device 16 on the four-leaf turntable 15 is located above the second station. The feeding device 16 can place the crucible at the second station. The motor 14 is started to drive the four-leaf turntable 15 to rotate 90 degrees. The cleaning device 17 is located above the second station. The cleaning device 17 can clean the crucible at the second station to prevent dust from affecting subsequent needle punching. The motor 14 is started again to drive the four-leaf turntable 15 to rotate 90 degrees. The detection device 18 is located above the second station. The detection device 18 detects the crucible at the second station. If the crucible has not been needled, motor 14 will not start and the four-leaf turntable 15 will not rotate, remaining stationary and waiting. If the needled crucible has been needled, motor 14 will start, driving the four-leaf turntable 15 to rotate 90 degrees again, causing the material changing device 19 to be positioned above the needled crucible. The material changing device 19 can then remove the needled crucible. Motor 14 will then start again, driving the four-leaf turntable 15 to rotate 90 degrees, and the material dispensing device 16 will rotate back to the workstation, placing the crucible on the workstation. This reciprocating motion completes the process of placing, cleaning, inspecting, and removing the crucible, resulting in high efficiency and saving labor costs.

[0054] Example 7

[0055] like Figures 1-9 As shown, the feeding device 16 includes a feeding cylinder 1601, which is fixed on a four-leaf turntable 15. Multiple crucibles 1602 can be vertically placed inside the feeding cylinder 1601. A cylinder 1603 is fixed on the four-leaf turntable 15, and its output end is connected to a moving frame 1604. The moving frame 1604 is fixedly connected to an upper moving rod 1605 and a lower moving rod 1611, respectively. Both upper moving rods 1605 are rotatably connected to an upper baffle 1606, which is mounted on a rotating column 1607. Each rotating column 1607 rotates on the four-leaf turntable 15. The upper end of the rotating column 1607 is threaded with an upper nut 1610, which fixes the upper baffle 1 1606, the upper isolation block 1608, and the upper baffle 2 1609 to the upper end of the rotating column 1607. The lower end of the rotating column 1607 is threaded with a lower nut 1612, which fixes the lower baffle 1 1613, the lower isolation block 1614, and the lower baffle 2 1615 to the lower end of the rotating column 1607. Both lower moving rods 1611 are rotatably connected to the lower baffle 1 1613.

[0056] The working principle of the above technical solution is as follows: Multiple crucibles 1602 are placed into the feeding cylinder 1601. The bottommost crucible 1602 falls on the upper baffle plate 1606. The cylinder 1603 is activated, and the output end of the cylinder 1603 retracts, driving the moving frame 1604 to move. This causes the upper moving rod 1605 and the lower moving rod 1611 to move, which in turn causes the upper baffle plate 1606 and the lower baffle plate 1613 to rotate on the four-leaf turntable 15 along with the rotating column 1607. The upper baffle plate 1606 separates from the edge of the crucible 1602, and the crucible 1602 in contact with the upper baffle plate 1606 falls. When the upper baffle plate 1606 rotates, the upper baffle plate 2 1609 rotates inward, blocking the crucible 1602 adjacent to the falling crucible 1602. If this causes the cylinder 1603 to reciprocate, the crucibles 1602 can fall one by one.

[0057] The four-leaf turntable 15 is equipped with two sets of baffles, one above and one below. The upper baffle bears the pressure of the crucible 1602 above it, while the lower baffle only needs to bear the pressure of the upper baffle and the crucible 1602. This reduces the pressure of the crucible on the lower baffle and prevents the crucible from becoming too heavy, bending or breaking the lower baffle, and causing damage to the equipment.

[0058] One or more upper isolation blocks 1608 can be placed between the upper baffle 1 1606 and the upper baffle 2 1609 to adjust the distance between the upper baffle 1 1606 and the upper baffle 2 1609, thereby accommodating crucibles 1602 of different heights.

[0059] Example 8

[0060] like Figures 1-9As shown, the cleaning device 17 includes a second cylinder 1701, which is fixed on a four-leaf turntable 15. The output end of the second cylinder 1701 is rotatably connected to a first rotating rod 1702. The first rotating rod 1702 is slidably connected to a first rotating wheel 1703. The first rotating wheel 1703 is connected to one end of a first belt 1704, and the other end of the first belt 1704 is connected to a second rotating wheel 1705. The second rotating wheel 1705 is connected to the output end of a fifth motor 1706, which is fixed on the four-leaf turntable 15. A second bracket 1707 is fixed to the end of the first rotating rod 1702. The second bracket 1707 is slidably connected to a first slider 1709, and the first slider 1709 is fixedly connected to one end of a second spring 1716. The other end of spring 1716 is fixedly connected to bracket 1707. Slider 1709 has moving rods 1708 connected to both ends. Both moving rods 1708 are slidably connected to bracket 1707. Slider 1709 is rotatably connected to rotating rod 1710. Rotating rod 1710 is rotatably connected to slider 1711. Slider 1711 is slidably connected to bracket 1707. Slider 1711 is fixedly connected to one end of spring 1712. The other end of spring 1712 is fixedly connected to slider 1713. Slider 1713 is slidably connected to bracket 1707. Slider 1713 is provided with brush 1714. Bracket 2 1707 is provided with brush 1715.

[0061] The working principle of the above technical solution is as follows: After the crucible 1602 is placed on the workstation by the feeding device 16, the motor 14 is started to drive the four-leaf turntable 15 to rotate 90 degrees, which drives the cleaning device 17 to rotate above the workstation. The cylinder 1701 is started to drive the rotating rod 1702 to move down, which in turn drives the support 1707 to move down, which drives the moving rod 1708 to contact the crucible 1602. The support 1707 continues to move down, which pushes the moving rod 1708 to move up, which drives the slider 1709 to move up inside the support 1707. This stretches the spring 1716, which drives the two sets of rotating rods 1710 to rotate, which drives the two sliders 1711 to slide towards the moving rod 1708, which in turn drives the spring 1712 and slider 1713 to move towards the moving rod 1708. When the rod 1708 slides, the brush 1714 at the lower end of the slider 3 1713 stops moving when it contacts the side of the crucible 1602. As the slider 2 1711 continues to move, it causes the spring 1712 to stretch. When the brush 2 1715 contacts the upper surface of the crucible 1602, the cylinder 2 1701 stops working, and the motor 5 1706 starts to drive the rotating wheel 2 1705 to rotate, which in turn drives the belt 1704 to rotate, drives the rotating wheel 1703 to rotate, drives the rotating rod 1702 to rotate, drives the bracket 2 1707 to rotate, and then drives the brush 2 1715 to clean the upper surface of the crucible 1602, and the brush 1714 to clean the side of the crucible 1602 to prevent dust from accumulating on the upper surface and side of the crucible 1602.

[0062] The lower end of bracket 2 1707 is hollow at the connection point with brush 2 1715, and the connection point of slider 3 1713 with brush 1 1714 is hollow. Both bracket 2 1707 and slider 3 1713 can be connected to water pipes, and water can be injected into brush 1 1714 and brush 2 1715 through the water pipes. During cleaning, brushing can be performed, while keeping the upper surface of crucible 1602 moist, which facilitates the fixation of carbon fiber monosheets.

[0063] Example 9

[0064] like Figures 1-9 As shown, the detection device 18 includes a detection camera 1801 and a transmission line 1802. The detection camera 1801 is fixedly connected to the transmission line 1802, and the detection camera 1801 is fixed on the four-leaf turntable 15.

[0065] The working principle of the above technical solution is as follows: After the cleaning device 17 cleans the crucible 1602, the motor 14 is started to drive the four-leaf turntable 15 to rotate 90 degrees. The detection camera 1801 rotates to the top of the workstation. The detection camera 1801 can detect whether the crucible has been needled. If it has not been needled, the motor 14 is in standby mode. If it has been needled, the motor 14 is started to drive the four-leaf turntable 15 to rotate 90 degrees again. The transmission line 1802 is connected to the controller.

[0066] Example 10

[0067] like Figures 1-9 As shown, the material changing device 19 includes a cylinder 1901, which is fixed to the four-leaf turntable 15 via a cylinder bracket 1903. The cylinder 1901 is fixedly connected to the central frame 1902. The four-leaf turntable 15 is slidably connected to the lifting rod 1905. A suction cup 1904 is fixed to the lower end of the lifting rod 1905. The lifting rod 1905 meshes with a gear 1906 for transmission. The gear 1906 is rotatably connected to the central frame 1902. The gear 1906 is fixedly connected to the wheel 1907, which is connected to the belt 1908. The belt 1908 is connected to the wheel 1909. The four rotating wheels 1909 are fixedly connected to the gear 1910. The gear 1910 meshes with the lifting rod 1911. The lifting rod 1911 is slidably connected to the four-leaf turntable 15. The lifting rod 1911 is fixedly connected to the suction cup 1912. The lifting rods 1905 and 1911 are both fixedly connected to the collection box 1913 through hoses. The collection box 1913 is fixedly connected to the hollow tube 1915 through the bent tube 1914. A piston 1916 slides inside the hollow tube 1915. The piston 1916 is fixedly connected to the output end of the cylinder 1917. The cylinder 1917 is fixed on the four-leaf turntable 15.

[0068] The working principle of the above technical solution is as follows: When the crucible is needled and transferred to the outer workstation, cylinder 1901 drives the center frame 1902 to move downwards, which in turn drives gears 1906 and 1910 to move downwards, lifting rods 1905 and 1911 to move downwards, and suction cups 1904 and 1912 to move downwards. If the upper surface of the crucible 1602 is uneven, with one side higher than the other, for example, one side of suction cup 1904 is higher than the other side of suction cup 1912, then suction cup 1904 will contact the upper surface of the crucible 1602 first, and suction cup 1904 and lifting rod 1905 will be unable to descend further. As the central frame 1902 continues to descend, it drives gear 1906 and lifting rod 1905 to rotate, which in turn drives wheel 3 1907 to rotate, belt 2 1908 to rotate, wheel 4 1909 to rotate, and lifting rod 2 1911 to continue moving downward until suction cup 2 1912 contacts the upper surface of crucible 1602. Then, cylinder 4 1917 is activated, causing piston 1916 to move backward, creating negative pressure inside hollow tube 1915. This causes air from lifting rod 1905 and lifting rod 2 1911 to enter collection box 1913 through hoses, and then through bend pipe 1914 into the cavity of hollow tube 1915. Under the influence of negative pressure, suction cup 1904 and suction cup 2 1912 lift the punctured crucible.

[0069] The material changing device 19 is equipped with two sets of suction cups, one 1904 and the other 1912, which can cope with uneven surfaces on the upper surface of the crucible, resulting in a more secure adsorption and preventing the crucible from falling off when it is removed.
