Description

Technical Field

[0001] The present invention relates to the technical field of electronic component manufacturing, and particularly relates to a fuse processing device and its processing technology. Background Art

[0002] In traditional fuse manufacturing processes, aluminum strips are usually used for processing. Specifically, the aluminum strip is placed on the processing table of the cutting equipment, and then the cutting equipment cuts out a plurality of independent fuses on the aluminum strip in sequence according to the set cutting program. 6 - 8 of the cut independent fuses are installed on a carrier to form a fuse group. The fuse group is transported to the downstream process, assembled onto the battery module, and then the carrier needs to be removed. A plurality of independent fuses in the fuse group are used to connect a plurality of batteries in the battery module.

[0003] The following problems exist in the above process:

[0004] 1. The independent fuses cut from the aluminum strip are prone to deformation during the process of being removed from the aluminum strip;

[0005] 2. It is difficult to ensure the accuracy of the installation positions of the independent fuses in the fuse group, resulting in poor quality after being installed on the battery module. Summary of the Invention

[0006] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a fuse processing device and its processing technology to solve the problems in the prior art that it is difficult to ensure the accuracy of the installation positions of the independent fuses in the fuse group and the independent fuses are prone to deformation.

[0007] To achieve the above purpose, the first aspect of the present invention adopts the following technical solution: A fuse processing technology, including the following steps:

[0008] Attach the aluminum strip to the bottom - releasing film;

[0009] Then attach the bottom - releasing film to the processing table of the cutting equipment;

[0010] The cutting equipment cuts out a plurality of independent fuses on the aluminum strip in sequence by using a full - cut combined with half - cut method according to the set cutting program;

[0011] Peel off the bottom - releasing film, and then separate the remaining aluminum strip to attach a plurality of independent fuses to the bottom - releasing film to form a fuse group.

[0012] The second aspect of the present invention adopts the following technical solution: A fuse processing device, which is applied to the processing in the above - mentioned fuse processing technology, includes:

[0013] A cutting equipment, which has a processing table;

[0014] The bottom - releasing film is adhered between the aluminum strip to be processed and the processing table.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the fuse processing technology of the present invention, the bottom - releasing film is used in cooperation with the aluminum strip. During the cutting process, the formed independent fuses are all adhered to the bottom - releasing film and will not fall off, so the independent fuses will not be deformed. At the same time, after the bottom - releasing film is peeled off, multiple independent fuses are adhered to the bottom - releasing film according to the positions during cutting. Then, the installation accuracy of multiple independent fuses in the formed fuse group is relatively high, and no additional carrier needs to be assembled, reducing the processing procedures.

[0017] 2. The fuse processing device in the present invention mainly consists of a cutting device and a bottom - releasing film. Its structural composition is simple. It is used to cut the aluminum strip in the fuse processing technology, ensuring that the independent fuses will not be deformed and multiple independent fuses in the formed fuse group have relatively high installation accuracy.

[0023] The present invention will be further described in detail below through specific embodiments:

[0024] As Figures 1 - 4 shown, an embodiment of the present invention provides a fuse processing device, including a cutting device and a bottom - releasing film 1. The cutting device has a processing table 2; the bottom - releasing film 1 is adhered between the aluminum strip 3 to be processed and the processing table 2.

[0025] The specific operation during the cutting process is as follows:

[0026] Attach the aluminum strip 3 to the bottomless film 1; then adhere the bottomless film 1 to the processing table 2 of the cutting device; start the cutting device and use the full-cut combined with half-cut method to sequentially cut on the aluminum strip 3 to form a plurality of independent fuses 4; peel off the bottomless film 1, and then separate the remaining aluminum strip 3 to adhere the plurality of independent fuses 4 to the bottomless film 1 to form a fuse group.

[0027] This fuse processing device uses the bottomless film 1 and the aluminum strip 3 to cooperate. During the cutting process, the formed independent fuses 4 are all adhered to the bottomless film 1 and will not fall off, so the independent fuses 4 will not be deformed; at the same time, after peeling off the bottomless film 1, the plurality of independent fuses 4 are adhered to the bottomless film 1 according to the positions during cutting, so the installation accuracy of the plurality of independent fuses 4 in the formed fuse group is relatively high, and there is no need to additionally assemble a carrier, reducing the processing procedures.

[0028] In this embodiment, the thickness of the aluminum strip 3 is 0.6 mm, and the cutting device is a laser cutting device. Using a laser cutting device for cutting can further ensure the processing accuracy of the fuse group and avoid deformation of the independent fuses 4 during cutting and forming. At the same time, the laser cutting speed is fast, and the supporting effect of the bottomless film 1 reduces the adjustment time during the processing, greatly improving the production efficiency.

[0029] To improve the bonding stability of the bottomless film 1 on the processing table 2, as Figure 1 and Figure 2 shown, according to another embodiment of the present invention, the fuse processing device further includes a vacuum adsorber, and the vacuum adsorber is cooperatively arranged on the processing table 2 and is used to provide an adsorption force between the bottomless film 1 and the processing table 2.

[0030] Based on the above scheme:

[0031] A plurality of adsorption mounting holes 5 are evenly distributed on the processing table 2, and the vacuum adsorber has a plurality of adsorption air pipes 6, and the plurality of adsorption air pipes 6 are respectively embedded in the plurality of adsorption mounting holes 5 in a one-to-one correspondence.

[0032] In this embodiment, the vacuum adsorber further has a suction pump connected to the plurality of adsorption air pipes 6. After the suction pump is started, a negative pressure adsorption force is formed at the plurality of adsorption mounting holes 5 through the plurality of adsorption air pipes 6 (only part of which is drawn in the attached drawing) to improve the bonding stability between the bottomless film 1 and the processing table 2 and ensure the cutting quality of the independent fuses 4.

[0033] Among them, the processing table 2 is rectangular, and the plurality of adsorption mounting holes 5 are distributed in two columns, and the two columns of adsorption mounting holes 5 are respectively distributed on both sides of the processing table 2 along its length direction to ensure that the bottomless film 1 is stably adhered to the processing table 2.

[0034] Further, the bottom-removing film 1 is a silicone protective film with a thickness of 75 μm. The silicone protective film has excellent adsorption properties and can be stably bonded and fixed to the processing table 2 and the aluminum strip 3 during use. Moreover, the silicone protective film also has high temperature resistance and can withstand a temperature range of -50°C to 200°C, which can meet the processing requirements.

[0035] The present invention also provides a processing method. According to another embodiment of the present invention, the fuse processing process includes the following steps:

[0036] Step S1: Attach the aluminum strip 3 to the bottom-removing film 1;

[0037] Step S2: Then adhere the bottom-removing film 1 to the processing table 2 of the laser cutting device;

[0038] Step S3: The laser cutting device sequentially cuts the aluminum strip 3 in a full-cut combined with half-cut manner according to the set cutting program to form a plurality of independent fuses 4;

[0039] Step S4: Peel off the bottom-removing film 1, and then separate the remaining aluminum strip 3 to adhere the plurality of independent fuses 4 to the bottom-removing film 1 to form a fuse group.

[0040] By using the cooperation of the bottom-removing film 1 and the aluminum strip 3, the independent fuses 4 formed during the cutting process are all adhered to the bottom-removing film 1 and will not fall off, so the independent fuses 4 will not be deformed; at the same time, after the bottom-removing film 1 is peeled off, the plurality of independent fuses 4 are adhered to the bottom-removing film 1 according to the positions during cutting, so the installation accuracy of the plurality of independent fuses 4 in the formed fuse group is relatively high, and no additional carrier needs to be assembled, reducing the processing procedures.

[0041] In step S3, the full-cut combined with half-cut manner is specifically as follows:

[0042] When the laser cutting device cuts the ear position of the independent fuse 4, the cutting depth is the thickness of the aluminum strip 3;

[0043] When the laser cutting device cuts the current-limiting position 41 of the independent fuse 4, the cutting depth is the sum of the thicknesses of the aluminum strip 3 and the bottom-removing film 1.

[0044] That is, when the laser cutting tool of the laser cutting device moves to the position of the lug of the independent fuse 4, the cutting depth of the laser cutting tool of the laser cutting device is set to the thickness of the aluminum strip 3, that is, 0.6 mm. At this time, the laser cutting tool of the laser cutting device only cuts on the aluminum strip 3; when the laser cutting tool of the laser cutting device moves to the current-limiting position 41 of the independent fuse 4, the cutting depth of the laser cutting tool of the laser cutting device is set to the sum of the thicknesses of the aluminum strip 3 and the bottom-release film 1, that is, 0.6 mm + 75 μm. At this time, the laser cutting tool of the laser cutting device will cut on the aluminum strip 3 and the bottom-release film 1; because the current-limiting position 41 of the independent fuse 4 needs to be cut in a circular path on the aluminum strip 3 (such as Figure 4 in the upper and lower sides of the current-limiting position 41 are both cut in a circular path, and after removing the two parts after the circular path cutting, the current-limiting position 41 of the independent fuse 4 is formed), this part is removed to form the current-limiting position 41 of the independent fuse 4. During this process, cutting is also performed on the bottom-release film 1, so that the part to be removed can be removed together during the process of peeling off the bottom-release film 1, optimizing the operation process.

[0045] It should be noted that: the design principle of the set cutting program is the prior art, and the set cutting program pointed out in the background art can be referred to. The main difference is only to change the cutting depth of the current-limiting position 41 of the independent fuse 4 from the original thickness of the aluminum strip 3 to the sum of the thicknesses of the aluminum strip 3 and the bottom-release film 1. Therefore, the set cutting program will not be described in detail here.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
