Description

Technical Field

[0001] The present application relates to the field of fuse assembly equipment, and in particular to a fuse sand filling and weighing mechanism. Background Art

[0002] During fuse assembly, an arc-extinguishing material is added. This process, called sand filling, is primarily intended to improve fuse safety and performance. When the fuse operates (melts), the arc-extinguishing material quickly absorbs the heat generated by the arc and neutralizes the ions in the arc, effectively extinguishing the arc and protecting circuits and equipment.

[0003] However, during the fuse production process, accurately controlling and verifying the weight of the arc-extinguishing material is a key step in ensuring fuse yield. This is because the weight of the arc-extinguishing material not only directly affects the fuse's arc-extinguishing effect, but may also affect other fuse properties, such as melting time and breaking current.

[0004] Therefore, how to conveniently and accurately obtain the weight of the filler in the fuse is a problem that needs to be solved. Utility Model Content

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-5 This application is described in further detail.

[0026] The embodiment of the present application discloses a fuse sand filling and weighing mechanism. Figure 1 and Figure 2 The fuse sand filling and weighing mechanism includes a clamping mechanism 1, a first weighing mechanism 2, a sand filling mechanism 3 and a second weighing mechanism 4. The first weighing mechanism 2, the sand filling mechanism 3 and the second weighing mechanism 4 are all correspondingly provided with an opening clamp mechanism 1. The opening clamp mechanism 1 is used to open the clamp holding the porcelain tube. The clamp holding the porcelain tube adopts the clamping clamp with patent number CN217061928U, so that the porcelain tube falls into the corresponding mechanism for weighing or sand filling operation.

[0027] The first weighing mechanism 2 is used to weigh the porcelain tube before sand filling. The first weighing mechanism 2 includes a first weight sensor 21 and a first scale support 22. The first scale support 22 is mounted on the first weight sensor 21. The sand filling mechanism 3 is used for the sand filling operation of the porcelain tube. In this embodiment, two groups of sand filling mechanisms 3 are provided. The second weighing mechanism 4 is used to weigh the porcelain tube after sand filling. The second weighing mechanism 4 includes a second weight sensor 41 and a second scale support 42. The second weight sensor 41 is mounted on the second scale support 42. The difference between the weight of the porcelain tube obtained by the second weighing mechanism 4 and the weight of the porcelain tube obtained by the first weighing mechanism 2 is the weight of the filler.

[0028] When the porcelain tube is rotated to the position of the first weighing mechanism 2 through the clamp, the clamp is opened by the clamp opening mechanism 1, the porcelain tube is released by the clamp and falls onto the first scale support 22. After the weight of the porcelain tube is obtained by the first weight sensor 21, the clamp opening mechanism 1 leaves the mechanism, and the clamp clamps the porcelain tube to the sand filling mechanism 3 to fill the porcelain tube with sand. After the sand filling is completed, it is transmitted to the second weighing mechanism 4, and the clamp is opened by the clamp opening mechanism 1. The sand-filled porcelain tube is released by the clamp and falls onto the second scale support 42. After the weight of the porcelain tube is obtained by the second weight sensor 41, the difference between this weight and the weight obtained by the first weight sensor 21 is calculated. This difference is the weight of the filler. Therefore, the weight of the filler in the fuse can be conveniently and accurately obtained. If the difference is qualified, it can be transferred to the next process. If it is unqualified, the unqualified product will be taken out, thereby ensuring the yield rate of the fuse.

[0029] Reference Figure 1 In some embodiments, the clamping mechanism 1 includes a first driving member 11, an clamping rack 12 and an clamping cam 13. The first driving member 11 adopts a telescopic cylinder, and the clamping rack 12 and the clamping cam 13 are engaged with each other. The first driving member 11 drives the clamping rack 12 forward or backward, and drives the clamping cam 13 to rotate. The clamping cam 13 is an elliptical cylindrical structure as a whole. When it is rotated to one side, the pin of the clamp is opened, and the clamp releases the porcelain tube. When it is rotated to the other side, the pin of the clamp is left, and the clamp clamps the porcelain tube, so that the clamp can be opened conveniently.

[0030] Reference Figure 3 In some embodiments, the first weighing mechanism 2 further includes a first anti-collision bar 23, which is disposed on one side of the first scale support 22. When the porcelain tube is rotated to the first weighing mechanism 2 via the clamp, the porcelain tube first passes over the first anti-collision bar 23, preventing the porcelain tube from deviating downward and colliding with the first scale support 22.

[0031] In some embodiments, the first weighing mechanism 2 further includes a first air blowing pipe 24, the outlet of which is directed toward the first scale support 22. Air is blown into the first scale support 22 through the first air blowing pipe 24 before sand filling to prevent foreign matter from affecting the weighing weight of the porcelain tube. In this embodiment, the first weighing mechanism 2 further includes a shock-absorbing column 25, which is used to support the first weight sensor 21, thereby effectively absorbing shock when the porcelain tube falls onto the first scale support 22.

[0032] Reference Figure 4In some embodiments, the sand filling mechanism 3 includes a sand filling component 31 and a shaking component 32. The shaking component 32 includes a second driving member 321, a third driving member 322, and a shaking clamp 323. The second driving member 321 drives the third driving member 322 to move. In this embodiment, the second driving member 321 is a telescopic cylinder, and the output end is connected to a smooth seat 324. The third driving member 322 is arranged on the smooth seat 324. The second driving member 321 drives the smooth seat 324 to move and drives the third driving member 322 to move; the third driving member 322 drives the shaking clamp 323 to clamp or release the porcelain tube; the sand filling component 31 includes a sand filling component 31. The sand hopper 311, the fourth driving member 312, the upper and lower sand filling plates 313, the sand filling nozzle 314, the sand filling die 315, and the fifth driving member 316. The fourth driving member 312 drives the sand filling hopper 311 to move in the vertical direction. The upper and lower sand filling plates 313 are arranged at the discharge end of the sand filling hopper 311. The sand filling nozzle 314 is arranged on the side of the upper and lower sand filling plates 313 away from the sand filling hopper 311. The upper and lower sand filling plates 313 are provided with mutually interpenetrating sliding grooves 317 and a material discharge through hole. The fifth driving member 316 drives the sand filling die 315 to move along the sliding groove 317. The sand filling die is connected to the material discharge through hole or covers the material discharge through hole.

[0033] After weighing, the porcelain tube is rotated to the sand filling mechanism 3 through the clamp, and the second driving member 321 drives the third driving member 322 to move forward. The third driving member 322 is a clamping cylinder, which drives the shaking clamp 323 to open, and the porcelain tube enters the shaking clamp 323. The third driving member 322 shakes the clamp 323 to clamp the porcelain tube, and the clamp is opened by the clamp opening mechanism 1. At this time, the porcelain tube is fixed by the shaking clamp 323, and the second driving member 321 drives the third driving member 322, that is, The shaking clamp 323 retreats to the bottom of the sand filling nozzle 314, the fourth driving member 312 drives the sand filling hopper 311 to move downward (the fourth driving member 312 is fixed on the equipment frame), and the fifth driving member 316 drives the sand filling die 315 forward, and brings the arc extinguishing material in the sand filling die 315 to the position of the blanking through hole. The arc extinguishing material falls into the sand filling nozzle 314 along the blanking through hole, and the sand filling nozzle 314 extends into the porcelain tube, and the arc extinguishing material enters the porcelain tube through the sand filling nozzle 314.

[0034] The vibration assembly 32 also includes a vibration base 325 and a voice coil motor 326. The voice coil motor 326 is mounted on one side of the vibration base 325. In this embodiment, the second cylinder is mounted on the vibration base 325, and the smooth base 324 slides on the vibration base 325. When the arc-extinguishing material enters the porcelain tube through the sand filling nozzle 314, the voice coil motor 326 is activated, causing the porcelain tube to vibrate through the vibration clamp 323, thereby more quickly filling the porcelain tube with arc-extinguishing material.

[0035] Reference Figure 5In some embodiments, the second weighing mechanism 4 further includes a sixth driving member 43, a material pulling block 44, a seventh driving member 45, and a lifting clamp 46. The sixth driving member 43 is a telescopic cylinder, and the seventh driving member 45 is a clamping cylinder. The sixth driving member 43 drives the material pulling block 44 to move in the vertical direction. The seventh driving member 45 is mounted on the material pulling block 44 and drives the lifting clamp 46 to clamp or release the porcelain tube. The lifting clamp 46 is located above the second scale support 42. After the weighing of the porcelain tube is completed, the sixth driving member 43 drives the lifting clamp 46 to descend to the position of the porcelain tube, and then the seventh driving member 45 drives the lifting clamp 46 to clamp the porcelain tube. The sixth driving member 43 then drives the lifting clamp 46 upward to the position of the porcelain tube clamp. The clamping mechanism 1 releases the porcelain tube clamp, and the porcelain tube clamp clamps the porcelain tube, and the tube can be transported to the next process.

[0036] In some embodiments, the second weighing mechanism 4 further includes a second air blow pipe 47, the outlet of which is directed toward the second scale support 42. This allows the second air blow pipe 47 to blow away foreign matter on the scale support before weighing the porcelain tube, thereby ensuring a more accurate weight determination. In this embodiment, a sand weighing anti-collision bar is also provided on one side of the second scale support 42.

[0037] The implementation principle of a fuse sand filling and weighing mechanism in an embodiment of the present application is as follows: when the porcelain tube is rotated to the position of the first weighing mechanism 2 through the clamp, the clamp is opened by the clamp opening mechanism 1, and the porcelain tube is released by the clamp and falls onto the first weighing support 22. After the weight of the porcelain tube is obtained by the first weight sensor 21, the clamp opening mechanism 1 leaves the mechanism, and the clamp clamps the porcelain tube to the sand filling mechanism 3 to fill the porcelain tube with sand. After the sand filling is completed, it is transmitted to the second weighing mechanism 4, and the clamp is opened by the clamp opening mechanism 1. The sand-filled porcelain tube is released by the clamp and falls onto the second weighing support 42. After the weight of the porcelain tube is obtained by the second weight sensor 41, the difference between this weight and the weight obtained by the first weight sensor 21 is calculated. This difference is the weight of the filler, so the weight of the filler in the fuse can be obtained conveniently and accurately.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
