The ceramic tube is fed to the first clamp of the ring rail device by the ceramic tube feeding device and sent to the inner cap assembly device. The inner cap assembly device assembles the inner cap to both ends of the ceramic tube. Then, the inner cap welding device welds the molten material to the inner cap and sends it to the main turntable through the semi-finished product transfer device. The outer cap assembly device completes the installation of the outer cap at the first end of the ceramic tube. Then, the ceramic tube sand filling device fills the ceramic tube with sand. Then, the outer cap assembly device installs the outer cap at the second end. Finally, the material is unloaded by the unloading device, realizing the fully automated assembly and welding of fuses, which greatly improves the production efficiency of fuses, reduces manual intervention, and reduces labor intensity. 2. By incorporating length and vacuum degree detection devices into the ceramic tube feeding device, defective ceramic tubes can be screened out promptly. A visual inspection camera in the inner cap assembly device inspects the inner caps during feeding, preventing unqualified inner caps from being installed on the ceramic tubes. This avoids assembling and welding defective inner caps and ceramic tubes, improving overall product yield and production efficiency. 3. A feeding device is located at the end of the main turntable, equipped with both good and defective product feeding mechanisms for product sorting. This integrates production and inspection, reducing unnecessary transfers and further improving production efficiency. 4. The ceramic tube sand filling device is equipped with a vibrator, ensuring more uniform sand filling within the ceramic tubes. 5. Using a ring track and turntable as the ceramic tube operating mechanism allows for the arrangement of corresponding inner cap assembly and welding devices, outer cap assembly devices, etc., within a smaller space.

The clamping device 100 then closes the first clamping clamp 11, and the ring rail device 10 drives the first clamping clamp 11 to move to the next station for subsequent processes. Preferably, the material block moving part 24 is a cylinder lifting part, which makes the ceramic tube feeding block approach or move away from the ring rail device, so that after the first clamping clamp picks up the ceramic tube, it drives the ceramic tube feeding block to descend and make room, and can move forward.

[0054] Please see Figure 1 , Figure 2 , Figure 12 , Figure 13The semi-finished product transfer device 50 includes a transfer moving component 51.

Component 51 is equipped with a steering clamp 52 for feeding the ceramic tube with the inner cap assembled on the ring rail device 10 into the main turntable 60; the transfer moving component 51 is equipped with a steering drive component 53, and the steering drive component 53 is equipped with the steering clamp 52, which is used to drive the steering clamp 52 to turn; the plane of the ring rail device 10 is perpendicular to the plane of the main turntable 60, and the steering clamp 52 is used to clamp the ceramic tube with the inner cap welded on the first clamping clamp 11 and rotate it to a perpendicular angle with the main turntable 60 to the second clamping clamp 61 of the main turntable 60. After the inner cap assembly and welding are completed, the ceramic tube is driven by the ring rail device 10 to move to the transfer moving assembly 51. Then, the steering clamp 52 on the transfer moving assembly 51 clamps the ceramic tube, the clamping device 100 opens the first clamping clamp 11, and the steering drive 53 rotates the ceramic tube from a horizontal state to a vertical state. The transfer moving assembly 51 drives the entire steering drive 53 to move to the position where it intersects with the main turntable 60. The clamping device 100, which is opposite to the second clamping clamp 61 at the hinge position on the main turntable 60, opens the first clamping clamp 11. The second clamping clamp 61 is moved to the position of the transfer moving component 51. The clamping device 100 closes the second clamping clamp 61, which then clamps the ceramic tube. The steering clamp 52 is released and moved by the transfer moving component to the junction of the ring rail device 10 for the next clamping and steering. The main turntable 60 and the ring rail device 10 rotate one division. The ring rail device 10 delivers a new ceramic tube with the inner cap assembled and welded. The main turntable 60 drives the empty second clamping clamp to the junction, and this cycle repeats. The steering drive component 53 can be a component that achieves rotation through a gear and rack mechanism, with the rack driven by a cylinder, or it can be a direct motor driving the steering. The transfer moving component 51 can be composed of a slide rail, a slider, a cylinder, etc., or it can be a synchronous belt and synchronous pulley, or it can be driven by a lead screw and nut, and is not limited to these.

The sand filling vibration clamp 85 is fixed on the flat vibrator 87. The preferred ceramic tube sand filling device 80 has three sets, but other numbers can be used, adjusted according to the actual production line speed. After the ceramic tube with one end cap assembled (i.e., the lower end), the horizontal vibration moving component 86 drives the sand filling vibration clamp 85 to move to the second clamping clamp 61, where the sand filling vibration clamp 85 clamps the ceramic tube. The clamp opening device 100 opens the second clamping clamp 61 located at the ceramic tube sand filling device 80. The horizontal vibration moving component 86 drives the ceramic tube to move below the outlet of the sand tank 82. Sand from the sand tank 82 fills the ceramic tube. At this time, the horizontal vibrator 87 operates, causing the ceramic tube to vibrate, which can make the sand filling in the ceramic tube more uniform. The structure of the preferred switching valve 83 can be found in the outlet switch of a fuse sheet melt welding machine patent, which will not be described in detail here. The outlets of the first and second sets of sand tanks 82 for filling arc-extinguishing material are the same size, while the third set is smaller and used for the final replenishment of arc-extinguishing material.

When the sand filling device is working, the sand quantity detection probe moves downward so that the lower end face of the sand quantity detection probe contacts the upper through hole of the semi-finished product that has been filled with sand. After the lower end face of the sand quantity detection probe contacts the arc-extinguishing material, it does not move. The sand filling hopper fixed seat continues to move downward, so that the distance between the upper end face of the sand quantity detection probe and the analog proximity switch decreases. The length of the sensing distance of the analog proximity switch is used to monitor whether the arc-extinguishing material on the inner wall of this semi-finished product is filled according to technical requirements. If the detection is continuously poor, the equipment will stop and alarm.

A flatness correction clamp is installed on the flatness correction finger assembly, and the flatness correction fingers are mounted on a flatness correction slide. A pneumatic component is installed below it, allowing for upward or downward movement. When the finished product on the product clamp of the main turntable 60 enters this station... The pneumatic assembly connects to the cylinder head, driving the flatness correction slide plate upwards. This causes the flatness correction finger to move upwards. When the flatness correction clamp reaches the open pin position of the product clamp on the main turntable 60, the pneumatic assembly on the flatness correction finger moves, causing the flatness correction clamp to clamp the open pin of the second clamping clamp on the main turntable 60, thus securing the second clamping clamp on the main turntable 60. Then, the flatness correction pull plate at the upper end of the finished product correction device resets via the pneumatic assembly, pulling the flatness correction slide plate. This causes the flatness correction pull plate mounted on the upper end of the slide plate to pull back, aligning the pins at both ends of the finished product to be vertical. The pneumatic assembly resets, completing the flatness correction of the finished product.

[0070] The present invention has the following working principle: First, the ceramic tube is fed into the first clamping clamp 11 of the ring rail device 10 by the ceramic tube feeding device 20. Then, the ceramic tube can be vacuum tested and length tested. The unqualified tubes are then transported to the inner cap assembly station and the inner cap welding station without inner cap assembly and welding. Finally, they are moved to the semi-finished product unloading device 17 for unloading. The qualified ceramic tubes are transported to the inner cap assembly station. First, they move to the one-end inner cap feeding mechanism 32 to assemble the inner cap at one end. Then, they move to the two-end inner cap feeding mechanism 34 to assemble the inner caps at both ends. Then, they move to the inner cap welding station. First, the melt is fed into the melt feeding module 43 and then inserted by the melt threading mechanism 411 to complete the welding of one end. Inside the ceramic tube assembled with inner caps at both ends, the molten material is a molten material with one end already bent. After the molten material enters, the positive and negative electrode components of the one-end welding module 41 are energized near the inner cap at one end for inverter resistance spot welding. Then, the molten material and inner cap at both ends are welded. Since the two ends of the molten material are not bent, they need to be bent by a bending mechanism first. Then, the two-end welding module 42 performs inverter resistance spray welding on the molten material of the inner cap at both ends. After the welding of one end and the two ends is completed, resistance testing and visual inspection are performed first. Qualified products are sent to the second clamping clamp 61 of the main turntable 60 through the semi-finished product hinge device. Unqualified products are unloaded from the ring rail device 10 through the semi-finished product defect unloading device 17. The qualified semi-finished products fed into the main turntable 60 are first fitted with outer caps by the outer cap assembly mechanism 71 at one end of the outer cap assembly device 70. After the first end of the semi-finished product is fitted with an outer cap, it is then filled with sand by the sand filling device. After the sand filling is completed, the outer cap assembly mechanism 72 at the other end of the outer cap assembly device 70 is used to fit the second end of the semi-finished product into a finished product. Then, length and visual inspection are performed. Products that fail the inspection are unloaded by the good product unloading mechanism 91, and products that pass the inspection are unloaded by the defective product unloading mechanism 92, and are unloaded to their respective storage positions. The corresponding detection devices on each device can detect unqualified ceramic tubes, inner caps, outer caps, semi-finished products, and finished products in real time. Unqualified products are not allowed to proceed to subsequent processes, which can reduce the time spent in intermediate links and improve production efficiency.
