Description

Technical Field

[0001] The utility model relates to the technical field of fuse production equipment, in particular to a fuse-link pay-off device. Background Art

[0002] A fuse is an electrical device that uses the heat generated by itself to melt the fuse element (also known as a fuse, fusible element, etc.) and disconnect the circuit when the current exceeds the specified value. Fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. As a short circuit and overcurrent protector, they are one of the most commonly used protective devices. The fuse element of a fuse plays a pivotal role in fuse processing.

[0003] In order to improve the fusing efficiency of the fuse link of the fuse, in the existing fuse production process, the fuse link usually needs to be input into a punch press for punching to form a specific shape structure; and the front side of the existing punch press is connected to a wire pay-off disk, and the punch press is fed by manual wire pay-off, but this has high labor intensity for workers and uneven wire pay-off, which affects the production efficiency of the product.

[0004] There is also a fuse wire winding straightening mechanism disclosed in Chinese patent publication No. CN218778506U. This scheme can realize automatic feeding, but the structure of the mechanism is relatively complex, and it is mainly suitable for the scene where the two ends of the fuse need to be straightened for feeding. If the subsequent punch does not press the fuse, the swing arm in this scheme will pull back the fed fuse under the action of gravity, affecting the normal operation of the punch.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] like Figures 1 to 6 As shown, a fuse-link pay-off device 10 of the present invention comprises a pay-off assembly 1 and a detection assembly 2 which are arranged side by side on the left and right.

[0030] In this embodiment, the wire-paying device 10 may further include an equipment platform 3 , and the wire-paying component 1 and the detection component 2 may both be installed on a table 31 of the equipment platform 3 .

[0031] like Figure 1 and Figure 3 The pay-off assembly 1 includes a pay-off drum 11 and a pay-off driving mechanism 12. The pay-off drum 11 is used to place the strip-shaped fuse 4 wound into a drum. The strip-shaped fuse 4 of this embodiment takes a silver strip as an example. The pay-off driving mechanism 12 drives the pay-off drum 11 to rotate to pay off the fuse 4.

[0032] The detection assembly 2 includes a detection body 21 and a sensor 22. The detection body 21 is provided with a detection groove 211 extending left and right, and the detection groove 211 is for the fuse 4 released by the pay-off reel 11 to pass through. The sensor 22 is a proximity switch 221 arranged at the bottom 2111 of the detection groove 211, and is used to detect the distance between the fuse 4 and the bottom 2111 of the detection groove.

[0033] By this, see Figure 4 and Figure 5The wire-releasing device 10 can be arranged at the front side of the process of the punch press 5, and the wire-releasing driving mechanism 12 is used to drive the wire-releasing reel 11 to rotate. The wire-releasing reel 11 rotates to release the wound fuse 4, and the released strip-shaped fuse 4 can pass through the detection groove 211 of the detection body 21 and then connect to the feed port of the punch press 5 (not shown). Since the two ends of the strip-shaped fuse 4 are respectively connected to the wire-releasing reel 11 and the punch press 5, when there is a surplus of fuse 4 released by the wire-releasing reel 11, the middle part of the strip-shaped fuse 4 will be vertically placed in the detection groove 211. At this time, the distance H between the fuse 4 and the proximity switch 221 is small or close to zero, and when the punch press 5 is continuously operated to release the fuse 4 After being pulled to the right, the middle part of the fuse 4 will be gradually raised away from the proximity switch 221 of the bottom 2111 of the detection slot 211. When the distance H between the proximity switch 221 and the fuse 4 increases to exceed the preset value, the wire-releasing driving mechanism 12 will be triggered to operate, and then the wire-releasing reel 11 will be driven to release the wire, so as to increase the margin of the strip-shaped fuse 4 to maintain the normal operation requirements of the punching machine 5, and the middle part of the strip-shaped fuse 4 will be lowered again, reducing the distance H between the fuse 4 and the proximity switch 221. When the distance H is less than the preset value, the wire-releasing driving mechanism 12 will be triggered to stop operating through the proximity switch 221 again to avoid excessive wire release.

[0034] Therefore, the wire-laying device 10 of the present invention can automatically lay out and replenish the strip-shaped fuse 4 according to the actual operation progress of the punch 5 to ensure that the punch 5 continuously and uninterruptedly punches the fuse 4, that is, it can realize automated wire-laying operation to greatly save manpower.

[0035] Of course, the punch press 5 can also be replaced with other equipment molds. The detection slot 211 can limit the fuse 4 to a certain extent to avoid the wire release deviation. The connection relationship and triggering method of the proximity switch 221 and the wire release drive mechanism 12 can adopt the existing technology.
