Description

Technical Field

[0001] This invention relates to the field of fuse processing technology, and more specifically to a fuse processing apparatus. Background Technology

[0002] A fuse, also known as a current fuse, primarily serves as overload protection. When an abnormal current occurs in a circuit, the fuse's temperature rises to a certain level, causing it to cut off the current and protect other components in the circuit. Compared to the older fuses that simply melt to cut off the current, the currently used resettable fuses deform to cut off the current after the temperature exceeds a certain safe level. These fuses commonly use shape memory metal (MMM) as their material. To ensure that the MMM "remembers" the shape within the fuse, it is necessary to process the fuse in an environment exceeding its transition temperature. Furthermore, when the temperature drops below the transition temperature, the fuse needs to be deformed to facilitate installation. However, the following problems exist during the molding process:

[0003] Because fuses are small and have poor heat storage capacity, their temperature fluctuates greatly, making it difficult to maintain a stable transition temperature within a fixed range. To ensure the fuse accurately "remembers" the deformed shape, the ambient temperature is often heated to a level far above the transition temperature. However, due to temperature limitations, the ambient temperature must be lowered below the transition temperature before the fuse can be processed again. Simultaneously, the ambient temperature being heated to a level far above the transition temperature requires a considerable cooling period, leading to decreased production efficiency. Furthermore, the device for reprocessing the fuse is located far from the device for accurately "remembering" the deformed shape, resulting in different operating temperatures for both. While this can be addressed by transferring the fuse using transfer equipment or manually, the spaced arrangement of these two devices increases the overall footprint of the fuse forming equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention aims to provide a fuse processing apparatus, comprising:

[0005] A forming mechanism, used to bend and shape the fuse; and

The fuse is deformed by the pressure heads.

[0008] The straightening mechanism is located at the downstream end of the forming mechanism. After the fuse completes the bending and forming action, the cooling section is used to cool the fuse. The cooled fuse is then transferred to the straightening mechanism.

[0009] The straightening mechanism includes a transmission wheel and a clamping module. The clamping module has a limit hole. Under the traction of the transmission wheel, the fuse passes through the clamping module and passes through the limit hole, so that the bent fuse is straightened again by the limit hole.

[0014] Preferably, the transmission wheel has two built-in rollers, which are driven by a drive assembly so that the fuse passes through the gap between the two rollers.

[0015] Preferably, the molding assembly further includes a base, and the pressure head is slidably connected to the base. A counterweight is pressed on the pressure head, and the weight of the pressure head and the counterweight presses on the fuse, forcing the fuse to deform and bend.

[0016] Preferably, the number of pressure heads is at least two, and the pressure heads are arranged along a straight installation direction;

[0017] The cooling section is located on both sides of the pressure head. The cooling section has a plurality of two air outlets. The air outlets are arranged along the installation direction so that the external airflow blows through the air outlets to the fuse on the thermoforming station.

[0018] Preferably, an insulation box is provided at the thermoforming station, and the fuse is fed into the insulation box and heated by the heating component;

[0019] The insulated box has side ears installed on its two outer sides, and the base is connected to a limiting part that matches the side ears. The limiting part and the side ears hold the fuse.

[0020] Preferably, the limiting part is slidably connected to the base, and a groove is provided on the limiting part, into which the slider on the base extends.

[0021] Preferably, an elastic unit is installed on the limiting part of the base near the clamping module. The elastic unit is connected to a base surface of the limiting part and the base.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0064] Terms involving attachment, connection, etc. (e.g., “connection” and “attachment”) refer to the relationship in which these structures are directly or indirectly fixed or attached to each other through an intermediate structure, as well as movable or rigid attachments or relationships, unless otherwise explicitly stated.

[0065] According to one embodiment of the present invention, Figure 1-10 As can be seen from the above, a fuse processing device includes a forming mechanism 100 and a straightening mechanism 200. The forming mechanism 100 is used to bend the fuse 500 into shape, and the straightening mechanism 200 is used to straighten the bent fuse 500.

[0066] The forming mechanism 100 includes a forming component 120, a heating component 130, and a support 110. The fuse 500 is made of shape memory metal. The heating component 130 is located below the forming component 120 and is used to heat the fuse 500. The support 110 is used to support the heating component 130 and the forming component 120. The support 110 serves as a connecting structure for the fuse thermoforming mechanism. The support 110 has a built-in thermoforming station located between the forming component 120 and the heating component 130, such that the forming component 120 and the heating component 130 are arranged sequentially on the upper and lower sides of the thermoforming station.

[0067] In this solution, the molding assembly 120 includes a pressing module 122; when the fuse 500 is transferred to the thermoforming station, under the action of a driving unit, the pressing module 122 approaches the heating assembly 130, and the pressing module 122 and the heating assembly 130 close together toward the thermoforming station. Specifically, the heating assembly 130 heats the fuse 500 to the transition temperature.

[0068] It should be noted that the deformation principle of fuse 500 is as follows: The shape memory alloy within fuse 500 is composed of different types of structural elements that are uniformly distributed. Although the size and electromagnetic force of these structural elements differ, each accelerates its own valence electron movement. Under certain temperature conditions, these elements are adjacent and in equilibrium. When fuse 500 is subjected to external force, the electromagnetic force within the shape memory alloy is disturbed, causing a slight angular adjustment in the plane of valence electron movement. This results in plastic deformation of fuse 500. During this plastic deformation, the movement of some adjusted valence electrons is not fully extended. When the temperature changes, the rate of valence electron movement changes accordingly. When the temperature returns to the equilibrium and extended state, the extended valence electron movement immediately returns to its previous rate, and the electromagnetic force changes accordingly. This causes the valence electron movement of adjacent structural elements to also adjust accordingly, returning them all to their original extended state. Thus, fuse 500 returns to the shape formed by the thermoforming mechanism of this fuse. The temperature at which the equilibrium and extended state is reached is the transition temperature.

[0069] The pressing module 122 includes at least one pressing head 1222, which is offset from the heating component 130. When the pressing module 122 approaches the heating component 130, the pressing head 1222 presses against the fuse 500 heated by the heating component 130, and bends the heated fuse 500 through the edge of the heating component 130, so that the fuse 500 is formed into a stable state. The stable state is the shape formed when the processing is not lower than the transition temperature. Below the transition temperature, the fuse 500 undergoes plastic deformation under external force, and when the temperature rises to... Upon temperature change, the fuse 500 automatically returns to its stable shape. By placing the forming component 120 and the heating component 130 within the same bracket 110, the pressing module 122 shapes the fuse 500 during the heating process. This allows the heating component 130 to continuously compensate for heat, ensuring that the fuse 500 maintains a temperature at least equal to or higher than the temperature change. This guarantees that the shaped fuse 500 can be completely restored during subsequent use. Furthermore, the fuse thermoforming mechanism automatically processes the fuse 500, improving production efficiency.

[0070] On the other hand, the pressing module 122 also includes a cooling section 1224. After the pressing head 1222 bends the heated fuse 500, the cooling section 1224 cools the bent fuse 500 so that the temperature of the fuse 500 is lower than the transition temperature. The straightening mechanism 200 is located at the downstream end of the forming mechanism 100. After the fuse 500 has completed the bending and forming action, the cooling section 1224 is used to cool the fuse 500. The cooled fuse 500 is then transferred to the straightening mechanism 200.

[0071] Specifically, the straightening mechanism 200 includes a transmission wheel 240 and a clamping module. The clamping module has a limiting hole. The fuse 500 is pulled by the transmission wheel 240 and moves along a certain direction. The clamping module and the transmission wheel 240 are arranged sequentially along this direction of movement. The transmission wheel 240 is located downstream of this direction of movement. The fuse 500 is transferred by the traction of the transmission wheel 240. Under the traction of the transmission wheel 240, the fuse 500 passes through the clamping module and passes through the limiting hole. The bent fuse 500 is straightened again by the limitation of the limiting hole, thereby completing the entire process of forming the fuse 500.

[0072] In a preferred embodiment, the transmission wheel 240 has two rollers built in, which are driven by a drive assembly 250. The drive assembly 250 drives one or both rollers, and the fuse 500 passes through the gap between the two rollers. The friction on the rollers drives the fuse 500.

[0073] The clamping module extends toward the forming mechanism 100. The clamping module includes an upper limit part 210 and a lower limit part 220. The upper limit part 210 and the lower limit part 220 clamp the fuse 500. Matching traction grooves 221 are provided in the upper limit part 210 and the lower limit part 220. When the upper limit part 210 and the lower limit part 220 are arranged opposite to each other, the two traction grooves 221 are spliced ​​together to form a limiting hole.

[0074] The upper limit section 210 extends along a straight line to the thermoforming station. A wire groove 211 is provided in the upper limit section 210 along the extension direction of the upper limit section 210. The wire groove 211 is connected to the traction groove 221. The cross-section of the wire groove 211 increases along the extension direction. The bent fuse 500 is pulled to the wire groove 211 and is restricted by the continuously shrinking wire groove 211. The degree of deformation of the fuse 500 gradually decreases. Finally, when the fuse 500 moves to the wire groove 211, the fuse 500 is at least approximately straight.

[0075] In this design, the traction groove 221 includes a terminal 2211, a corner section 2212, and an initial end 2213. The terminal 2211, corner section 2212, and initial end 2213 are connected in sequence to form an L-shaped traction groove 221. The traction groove 221 guides the fuse 500 and adjusts the direction of movement of the fuse 500. The direction of the transmission wheel 240 pulling the fuse 500 is perpendicular to the direction in which the forming mechanism 100 delivers the fuse 500, thereby reducing the length of the entire processing device. At the same time, the corner section 2212 is used to tension the fuse 500, thereby more effectively straightening the fuse 500. The corner section 2212 is rounded, the terminal 2211 is close to the transmission wheel 240, and the initial end 2213 is close to the thermoforming station.

[0076] In this design, there are at least two pressure heads 1222, and the heating assembly 130 includes at least two heating heads 132. The heating heads 132 and pressure heads 1222 are staggered. Under the action of a driving unit, the heating heads 132 and pressure heads 1222 engage with each other. Specifically, there are three pressure heads 1222, which are arranged along a straight installation direction. This installation direction is consistent with the direction of movement of the fuse 500 within the forming assembly 120. The number of heating heads 132 is consistent with the number of pressure heads 1222, so that the fuse 500 is processed into a wave shape. The surface of the pressure head 1222 that contacts the fuse 500 is the forming surface. Preferably, the forming surface is arc-shaped. During the pressing and forming process, the peak position of the fuse 500 is arc-shaped due to the restriction of the forming surface, which reduces the shear stress of the pressure head 1222 on the fuse 500, thereby avoiding shear damage to the fuse 500 by the pressure head 1222 during bending.

[0077] Furthermore, the cooling section 1224 is located on both sides of the pressure head 1222. The cooling section 1224 has a plurality of two air outlets 12241. The air outlets 12241 are arranged along the installation direction, so that the external airflow blows through the air outlets 12241 to the fuse 500 on the thermoforming station, so that the air outlets 12241 can blow evenly to different parts of the fuse 500, thereby ensuring that the temperature on the fuse 500 drops evenly.

[0078] Furthermore, the pressing module 122 also includes a base 1221, which is mounted on the drive unit or the bracket 110. The pressing head 1222 is slidably connected to the base 1221, and a counterweight 1226 is pressed on the pressing head 1222. Under the drive of the drive unit, the weight of the pressing head 1222 and the counterweight 1226 presses onto the fuse 500. When the pressing head 1222 contacts the fuse 500, the base 1221 slides relative to the pressing head 1222, so that the counterweight 1226, which originally applied force to the base 1221, presses onto the fuse 500 with its own weight, thereby forming the shape of the fuse 500 by the weight of the pressing head 1222 and the counterweight 1226.

[0079] Specifically, the top of the pressure head 1222 extends outward to form a load-bearing part, and a positioning post is vertically provided on the upper surface of the load-bearing part. The counterweight 1226 is placed on the load-bearing part and is sleeved on the positioning post to limit the offset of the counterweight 1226.

[0080] In one embodiment, the load-bearing portion on the pressure head 1222 is in contact with all the pressure heads 1222, thereby applying pressure to the pressure head 1222 through the same counterweight 1226, so that the counterweight 1226 is distributed to different positions of the fuse 500 via the multiple pressure heads 1222.

[0081] However, in the above embodiments, the pressure applied to each pressure head 1222 is difficult to control, which can easily lead to insufficient pressure in some parts of the fuse 500 and the shape of the final formed part cannot meet the processing requirements. Therefore, preferably, each pressure head 1222 and its corresponding counterweight 1226 constitute a pressing molding module. The weights of any two pressing molding modules are different, so that the pressure applied to each pressure head 1222 can be adjusted independently, thereby facilitating precise control of the pressure of each pressure head 1222 on the pressing module 122.

[0082] In a preferred embodiment, the bracket 110 includes a first connecting portion 111, a driving portion is mounted on the first connecting portion 111, and the driving portion drives the molding assembly 120 and / or the heating assembly 130, such that the molding assembly 120 moves relative to the heating assembly 130.

[0083] The first connecting part 111 includes at least a vertically arranged guide post 1112, which is slidably connected to a sliding plate 112. The driving part drives the sliding plate 112 to slide along the axial direction of the guide post 1112. The forming component 120 or the heating component 130 is mounted on the sliding plate 112.

[0084] In this embodiment, specifically, the driving unit includes a first driving unit 121 and a second driving unit 131. The first driving unit 121 is used to drive the molding assembly 120, and the second driving unit 131 is used to drive the heating assembly 130. The molding assembly 120 and the heating assembly 130 are driven by the first driving unit 121 and the second driving unit 131 to move closer to each other and finally move to the thermoforming station to process the fuse 500 placed on it. The base 1221 and the sliding plate 112 are connected by a column, so that a gap is reserved between the base 1221 and the sliding plate 112 to support the counterweight 1226.

[0085] Furthermore, the bracket 110 also includes a second connecting part 113, which is mounted on the first connecting part 111; the first connecting part 111 also includes a base plate 1111, on which the guide post 1112 is mounted, and the second connecting part 113 is also supported on the base plate 1111.

[0086] On the other hand, a heat preservation box 140 is installed on the second connecting part 113. The heat preservation box 140 is located on the thermoforming station. The second driving part 131 is used to drive the heating component 130 to extend into the heat preservation box 140. The fuse 500 is sent into the heat preservation box 140 and heated by the heating component 130. The heat preservation box 140 includes an outer cover 142, which has a cylindrical structure and covers the heating component 130. The inner wall of the outer cover 142 is attached with heat preservation blocks, so that the temperature inside the heat preservation box 140 is always relatively high, thereby preheating the fuse 500 transferred to the heat preservation box 140, so that the fuse 500 can reach the transition temperature more quickly, thereby increasing the processing speed and improving efficiency.

[0087] Furthermore, side ears 141 are installed on the two outer sides of the insulation box 140. The pressing module 122 also includes a limiting part 1223, which is set corresponding to the side ears 141. When the pressing module 122 approaches the heating component 130, the limiting part 1223 and the side ears 141 clamp the fuse 500. Specifically, the limiting part 1223 has a first limiting groove 12231, and the side ears 141 have a second limiting groove 1411. When the limiting part 1223 approaches the side ears 141, the first limiting groove 12231 and the second limiting groove 1411 are combined to form the cross-sectional shape of the fuse 500, and the position of the fuse 500 is restricted by the first limiting groove 12231 and the second limiting groove 1411.

[0088] On the other hand, the limiting part 1223 is provided with a vertically arranged sliding groove 12232. The base 1221 is connected to the sliding groove 12232 by a slider on the base 1221 so that it is slidably connected to the limiting part 1223. After the limiting part 1223 contacts the side ear 141, the base 1221 can continue to move downward, thereby increasing the downward stroke of the pressure head 1222. Specifically, the downward stroke of the base 1221 is limited by the length of the sliding groove 12232.

[0089] An elastic unit 1227 is installed on the limiting part 1223 on the side of the base 1221 near the clamping module. The elastic unit 1227 is connected to a base surface of the limiting part 1223 and the base 1221. The limiting part 1223 and the corresponding side ear 141 clamp the fuse 500 through the elastic deformation of the elastic unit 1227.

[0090] During the pressing step performed by the molding mechanism 100, the fuse 500 is bent, which increases the overall length of the fuse 500 entering the thermoforming station. The original length of the fuse 500 in the thermoforming station is insufficient to meet the length requirements of the bent fuse 500. Therefore, it is necessary to compensate the fuse 500 from the outside into the thermoforming station. However, the fuse 500 entering the straightening module has already been processed. If it is compensated into the thermoforming station, it will cause an error in the fuse 500 of the previous heat processing. Therefore, through the elastic deformation of the elastic unit 1227, the limiting part 1223 on the base 1221 near the straightening module and the side ear 141 clamp the fuse 500 to prevent the fuse 500 from shifting at that point. Secondly, during the process of straightening the fuse 500, by clamping both ends of the fuse 500 and applying tension to one end, the bent fuse 500 can be straightened more effectively.

[0091] In a preferred embodiment, the heating head 132 includes a contact and a heating element, the heating element being sleeved inside the contact, the contact contacting the fuse 500 and bending the fuse 500 through the edges of the contact. The straightening mechanism 200 also includes an adjustment component 250. Specifically, the lower limit part 220 is mounted on a base of the straightening mechanism 200, and the upper limit part 210 is slidably connected to the base. The adjustment component 250 adjusts the gap between the upper limit part 210 and the lower limit part 220 by driving the upper limit part 210. Although the cooling part 1224 cools the fuse 500, the temperature of the fuse 500 is still higher than the room temperature. If the fuse 500 moves in the closed-loop limiting hole, heat will accumulate in the limiting hole. Therefore, setting the upper limit part 210 and the lower limit part 220 to have a gap can effectively dissipate heat. Preferably, the adjustment component 250 includes a bolt 251, and the upper limit part 210 is moved by rotating the bolt 251.

[0092] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details.
