Description

Technical Field

[0001] The utility model relates to the technical field of fuse production, in particular to an automatic thread rolling head mechanism. Background Art

[0002] At present, the commonly used existing technology in the industry is as follows: the existing fuse wire cutting process is all manual wire cutting, and the manual production process is as follows: after the employee wraps the fuse on a strip-shaped fixture and welds it in the previous process, he uses scissors to cut off the fuse heads at one end of the hand-welded finished product one by one, and then turns it over and cuts the fuse head at the other end.

[0003] Disadvantages of manual production:

[0004] ①The product is too small, which is not conducive to manual cutting and poses a safety hazard.

[0005] ② The production method is inefficient, labor costs are high, operator training time is long, product quality is unstable, process integration is not conducive, and handling waste is high.

[0006] In view of the existing demand for automated equipment for fuse production, in order to improve product quality and production qualification rate, there are several ways of grinding after welding in the current fuse production process, but there are the following problems:

[0007] ① Milling cutter grinding: The milling cutter is installed on the motor. The motor runs quickly up and down to remove the fuse through the milling cutter blade. The welding may have inconsistent welding surface height. The copper cap of the product may be scratched during grinding, affecting the performance of the product. It is not easy to remove the glass fiber on the fuse during grinding, which affects the subsequent process and is not conducive to cap pressing, resulting in unstable product quality and low production qualification rate.

[0008] ② Imitation scissors wire head: Like manual labor, the imitation scissors are made into a mechanism in automation to cut the fuse head. This has disadvantages. The inconsistent height of the tin surface after welding causes some products to not be completely cut flat on the copper cap hole, and a small section of the fuse is exposed on the surface, which also affects the subsequent process and is not conducive to cap pressing, resulting in unstable product quality, increased machine failure rate, and low production qualification rate.

[0009] In summary, the problems of the prior art are: 1) the production method of manually cutting fuse heads is inefficient, with high labor costs, long training time for operators, unstable product quality, high defect rate, disadvantageous process integration, and high handling waste. 2) Defects in automated equipment.

[0010] Therefore, a thread rolling mechanism with excellent performance and low cost is in urgent need of research in automation. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The utility model embodiment provides an automatic thread rolling head mechanism, which can roll the product into threads, such as Figure 1 As shown, it includes a turntable 1 and a thread rolling mechanism 5, the turntable 1 rotates in the horizontal direction, and a plurality of main clamps 2 are equidistantly distributed in a ring along the outer circumference of the turntable 1, the main clamps 2 are used to clamp the product so that the product rotates with the turntable 1, and a thread rolling station is arranged along the rotation path of the product, the thread rolling station clamps and rolls the product, and the thread rolling station consists of a clamping mechanism 4 and a thread rolling mechanism 5; the thread rolling mechanism 5 is arranged adjacent to the clamping mechanism 4, the clamping mechanism 4 has two clamps that can move relative to each other, and the thread rolling mechanism 5 has a file that can reciprocate in the horizontal direction, the file is a miniature file 515, which cuts off the tail fuse head of the product clamped by the two clamps; after the tail fuse head of the current product is cut off, the turntable 1 rotates a certain angle and the next product enters the thread rolling station for clamping and thread rolling.

[0039] The automatic thread rolling head mechanism provided by the embodiment of the utility model is integrated in the automated production equipment, does not require manual participation, adopts automated equipment to replace manual production, eliminates the manual cutting of fuse heads, and also realizes the state where the fuse is not cut cleanly after automated welding. The use of automated equipment to replace the manual cutting of fuse heads improves production efficiency, saves a lot of labor, and improves product quality. The thread rolling action steps are as follows: the product is clamped by the main clamp on the turntable and transferred to its thread rolling station. First, the clamping mechanism 4 clamps the product, and then the thread rolling mechanism 5 moves downward. The reciprocating motion of the motor drives the micro file 515 to cut off the tail fuse head.

[0040] The thread rolling mechanism 5 mentioned above is described below by way of example. Figure 3 As shown, the thread rolling mechanism 5 also includes a motor, which is a brushless motor 509. The output end of the brushless motor 509 is connected to the tail of the micro file 515 through an eccentric linear reciprocating mechanism. The output end of the brushless motor 509 drives the micro file 515 to reciprocate through the eccentric linear reciprocating mechanism to roll the product.

[0041] The following is an example of the eccentric wheel linear reciprocating mechanism mentioned above. Figure 3 and Figure 4 As shown, the eccentric wheel linear reciprocating mechanism includes an eccentric wheel 510 and a track formed by two blocks 512 arranged opposite to each other. The eccentric wheel 510 has an eccentric shaft hole A and a central shaft hole. The eccentric shaft hole A is connected to the rotor end of the brushless motor 509. A second connecting block 518 is slidably connected in the track. The central shaft hole of the eccentric wheel 510 is pin-connected to the second connecting block 518 through a double fisheye joint 508, driving the second connecting block 518 to reciprocate along the length direction of the track. The rotor end of the brushless motor 509 drives the eccentric wheel 510 to rotate with the eccentric shaft hole A as the center. The central shaft hole of the eccentric wheel 510 drives the second connecting block 518 to reciprocate along the length direction of the track through the double fisheye joint 508, thereby realizing the reciprocating motion of the micro file 515.

[0042] In order to improve the stability of the micro file 515 during reciprocating motion, a fixing rod 514 is installed at the tail of the micro file 515, and a copper sleeve 516 is installed at one end of the fixing rod 514 away from the micro file 515. The copper sleeve 516 is connected to the second connecting block 518 through a guide rod 517, and a linear bearing seat 513 is sleeved on the outside of the guide rod 517. The linear bearing seat 513 and the guide rod 517 limit the reciprocating motion trajectory of the micro file 515, thereby improving the stability of the micro file 515 during reciprocating motion. The guide rod 517 passes through the copper sleeve 516 and is connected to the second connecting block 518, wherein the copper sleeve 516 passes through the linear bearing seat 513. The other end of the guide rod 517 is connected to the fixed shaft. The fixing rod 514 fixes the micro file 515 in a hugging manner. The brushless motor 509 rotates rapidly, driving the file to reciprocate to cut off the fuse head. The limit block 503 is fixed on the vertical plate, which can control the downward movement of the cylinder, that is, the distance between the micro file 515 and the product.

[0043] To adjust the thread rolling height, continue to refer to Figure 3 The thread rolling mechanism 5 further comprises an L-shaped plate composed of a second bottom plate 501 and a second vertical plate 504 arranged vertically, a second cylinder 502 is installed on the top of the second bottom plate 501, a slider plate 505 is arranged parallel to the side of the second vertical plate 504, two parallel slideways are arranged in the height direction of the second vertical plate 504, a slider 506 is arranged at a relative position between the slider plate 505 and the slideway, and the slider 506 is slidably connected with the slideway, a limit block 503 is arranged at the bottom of the slideway, and the side of the slider plate 505 away from the slider 503 is connected to the driving end of the second cylinder 502 through a single fisheye joint. The driving end of the second cylinder 502 drives the slider plate 505 to move upward or downward, and the slider plate 505 drives the slider 506 to move upward or downward along the slideway, thereby realizing the adjustment of the thread rolling height.

[0044] To adjust the thread rolling angle, continue to refer to Figure 3 The side pin of the slider plate 505 is connected with an adjustment plate 507, a second support plate 519 is installed on the top of the adjustment plate 507, a motor fixing plate 511 is installed on the top of the second support plate 519, and a distance adjustment slot is provided between the second support plate 519 and the motor fixing plate 511. By moving left and right, the effective distance of the file can be used more. The brushless motor 509 is fixed on the motor fixing plate 511. The adjustment plate 507 is rotated clockwise or counterclockwise to adjust the angle of the motor fixing plate 511. The eccentric wheel linear reciprocating mechanism is integrated on the motor fixing plate 511, thereby adjusting the thread rolling angle.

[0045] The clamping mechanism 4 mentioned above is described below by way of example. Figure 2 As shown, the clamping mechanism 4 has two clamps that can move relative to each other, namely a first clamp 407 and a second clamp 408, which clamp the product between the two clamps to keep the product in a stationary state.

[0046] Furthermore, the clamping mechanism 4 also includes a first base plate 401, a first vertical plate 402 is installed on the top of the first base plate 401, a first support plate 403 is installed on the top of the first vertical plate 402, a clamping seat 404 is installed on the top of the first support plate 403, a cylinder fixing plate 412 is installed on the right side of the top of the clamping seat 404, a first cylinder 411 is installed on the left side of the cylinder fixing plate 412, a rotating joint 410 is installed on the left end of the first cylinder 411, and the rotating joint 410 is hinged to the two clamps through a first connecting block 405, and an upper cover plate 409 is arranged above the hinge between the clamp and the first connecting block 405, and the upper cover plate 409 is connected to the clamping seat 404 through a support column 406. A clamping mechanism 4 is provided which realizes forward and backward movement through a first cylinder 411: a rotating joint 410 is fixed on the head of the first cylinder 411, and the first clamping jaws 407 and the second clamping jaws 408 are connected together by a clamp connecting block. When the first cylinder 411 extends and retracts backward, the clamping jaws contract to clamp the product, ensuring that the thread rolling action does not shake the product left and right.
