Description

Technical Field

[0001] This application relates to the technical field of fuse welding auxiliary tools, and particularly relates to a pair of tweezers. Background Art

[0002] Electronic devices such as explosion-proof mobile phones and battery protection boards usually have temperature fuses to ensure the safe operation of the electronic devices. Since the temperature fuse is very sensitive to the welding temperature, during welding, if the temperature at the welding site is transmitted to the inside of the temperature fuse and exceeds the melting temperature of the temperature fuse, the temperature fuse will melt from the inside, resulting in irreparable damage to the temperature fuse. At this time, only a new temperature fuse can be replaced and welded again, resulting in a high defective rate of welding. Utility Model Content

[0003] This application provides a pair of tweezers, aiming to solve the technical problem that the temperature fuse is easily melted during welding.

[0004] In some embodiments of this application, a pair of tweezers is provided, including:

[0005] Tweezers arms, having a first end and a second end, the first ends of the two tweezers arms are fixedly connected, and the second ends of the two tweezers arms are spaced apart;

[0006] A heat absorbing member, connected to the second end of the tweezers arm, the heat absorbing member is used to contact the object to be clamped to absorb heat; and,

[0007] A heat conducting member, having a heat collecting end and a heat dissipating end, the heat conducting member is arranged on the tweezers arm, the heat collecting end of the heat conducting member is connected to the heat absorbing member, the heat dissipating end of the heat conducting member extends along the direction away from the second end of the tweezers arm, and the heat collecting end conducts the heat from the heat absorbing member to the heat dissipating end for heat dissipation.

[0008] In some embodiments, the heat conducting member includes a heat pipe;

[0009] The two tweezers arms have inner arm surfaces arranged oppositely, and the heat pipe is arranged on the inner arm surface of the tweezers arm along the extending direction of the tweezers arm.

[0010] In some embodiments, the heat conducting member further includes a heat dissipating liquid;

[0011] The heat dissipating liquid is filled in the heat pipe, and the heat dissipating liquid is used to absorb the heat of the heat collecting end and evaporate to form steam and flow towards the heat dissipating end.

[0012] In some embodiments, the shape of the heat pipe is a flat tube;

[0013] A groove is arranged on the inner arm surface of the tweezers arm, the heat pipe is installed in the groove, and one side surface of the heat pipe exposes the groove.

[0014] In some embodiments, the material of the heat absorber is a flexible heat absorber, and the heat collecting end of the heat conducting member is fixed to the second end of the tweezer arm through the heat absorber.

[0015] In some embodiments, the heat absorber is a metal mesh provided with mesh holes for adsorbing a heat dissipation medium, and the heat absorbed by the heat absorber is also dissipated through the heat dissipation medium.

[0016] In some embodiments, the tweezer further includes a heat dissipation member;

[0017] The first ends of the two tweezer arms are respectively connected to the heat dissipation member, the heat dissipation end of the heat conducting member is connected to the heat dissipation member, and the heat dissipation member is used for dissipating the heat on the heat dissipation end.

[0018] In some embodiments, the heat dissipation member includes a connecting portion;

[0019] The connecting portion is connected to the first end of the tweezer arm, the heat dissipation end of the heat conducting member is connected between the tweezer arm and the connecting portion, and a heat conducting medium is filled between the heat dissipation end and the connecting portion for transferring the heat of the heat dissipation end to the connecting portion.

[0020] In some embodiments, the heat dissipation member further includes a plurality of heat dissipation fins;

[0021] The plurality of heat dissipation fins are connected to the connecting portion and are spaced apart from each other, and the heat of the connecting portion is dissipated through the plurality of heat dissipation fins.

[0022] In some embodiments, the tweezer further includes an electrically conductive member;

[0023] The electrically conductive member is disposed on the outer surface of the tweezer arm and covers the touch portion of the tweezer arm.

[0024] According to the tweezer in the above embodiments, during welding, the second ends of the two tweezer arms can be used to clamp at the clamping point on the lead. When the heat at the welding point is transferred to the clamping point, since the heat absorber is connected to the second end of the tweezer arm, the heat absorber can be in contact with the lead. The heat absorber absorbs most of the heat transferred from the lead at the clamping point, thereby reducing the heat transferred from the lead to the inside of the fuse body. Also, since the heat absorber is connected to the heat collecting end of the heat conducting member, the heat absorbed by the heat absorber can be quickly transferred to the heat dissipation end through the heat conducting member for heat dissipation, so as to prevent the heat absorber from accumulating heat, thereby improving the continuous heat dissipation ability of the tweezer.

[0025] Thus, when the tweezers are clamped at the clamping point during the soldering process, the tweezers can absorb the heat on the pin at the clamping point to reduce the temperature directly transmitted from the pin to the inside of the fuse body, thereby effectively reducing the risk of the fuse body melting and facilitating the improvement of the yield of soldering the thermal fuse. In addition, the tweezers provided in this application do not require special training for the soldering personnel, nor do they require the development of dedicated heat dissipation soldering tooling for different thermal fuses, and have strong versatility.

Detailed Embodiments

[0035] The present application will be further described in detail below with reference to specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are denoted by related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid overshadowing the core part of the present application. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0036] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment and do not mean to be essential components and / or sequences.

[0037] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0038] The thermal fuse 1 is used to cut off the circuit when overheating occurs during the operation of the electronic device to avoid hazards such as fire. As Figure 1 shown, the thermal fuse 1 may include a fuse body 11 and pins 12, and a fusible body that can be melted at high temperature is provided inside the fuse body 11. For example, taking the thermal fuse 1 at 85°C as an example, when welding the thermal fuse 1 at the welding point a, the high-temperature heat at the welding point a will be transmitted along the pins 12 to the inside of the fuse body 11. If the temperature inside the fuse body 11 exceeds 85°C, the fusible body will melt, and the thermal fuse 1 will be irreversibly damaged. At this time, only a new thermal fuse 1 can be replaced and welded again, resulting in a relatively high defective rate of the welding of the thermal fuse 1 and causing waste of the thermal fuse 1.

[0039] To better weld the thermal fuse 1, the present application provides a pair of tweezers 2, as Figure 2 and Figure 3As shown, the tweezers 2 may include tweezer arms 21, a heat absorber 22, and a heat conductor 23. The tweezer arms 21 have a first end 211 and a second end 212. The first ends 211 of the two tweezer arms 21 are connected and fixed, and the second ends 212 of the two tweezer arms 21 are spaced apart. The heat absorber 22 is connected to the second end 212 of the tweezer arm 21, and the heat absorber 22 can be used to contact the object to be clamped to absorb heat. The heat conductor 23 has a heat collection end 231 and a heat dissipation end 232. The heat conductor 23 is disposed on the tweezer arm 21. The heat collection end 231 of the heat conductor 23 is connected to the heat absorber 22, and the heat dissipation end 232 of the heat conductor 23 extends in a direction away from the second end 212 of the tweezer arm 21. The heat collection end 231 can conduct the heat from the heat absorber 22 to the heat dissipation end 232 for heat dissipation.

[0040] In this way, during soldering, the second ends 212 of the two tweezer arms 21 can be used to clamp at the clamping point b on the pin 12. When the heat at the soldering point a is transferred to the clamping point b, since the heat absorber 22 is connected to the second end 212 of the tweezer arm 21, the heat absorber 22 can contact the pin 12. The heat absorber 22 will absorb most of the heat transferred on the pin 12 at the clamping point b, thereby reducing the heat transferred from the pin 12 to the inside of the fuse body 11. Also, since the heat absorber 22 is connected to the heat collection end 231 of the heat conductor 23, the heat absorbed by the heat absorber 22 can be quickly transferred to the heat dissipation end 232 through the heat conductor 23 for heat dissipation, so as to prevent the heat absorber 22 from accumulating heat, thereby improving the continuous heat dissipation ability of the tweezers 2.

[0041] Thus, when the tweezers 2 are clamped at the clamping point b during the soldering process, the tweezers 2 can absorb the heat on the pin 12 at the clamping point b to reduce the temperature directly transferred from the pin 12 to the inside of the fuse body 11, thereby effectively reducing the risk of the fuse body 11 being melted, which is beneficial to improving the yield of soldering the temperature fuse 1. In addition, the tweezers 2 provided in this application do not require special training for the soldering personnel, nor do they require the development of a dedicated heat dissipation soldering tooling for different temperature fuses 1, and have strong versatility.

[0042] Among them, according to the different soldering habits of the soldering personnel, the above-mentioned soldering point a can be set at the end of the pin 12 away from the fuse body 11, or can be set at any other position on the pin 12. The above-mentioned clamping point b can be located between the soldering point a and the fuse body 11. This application does not make special restrictions on the specific positions of the soldering point a and the clamping point b on the pin 12.

[0043] In some embodiments, as Figures 3 to 5 shown, the heat conductor 23 may include a heat pipe 233; the two tweezer arms 21 may have relatively arranged inner arm surfaces 213, and the heat pipe 233 may be disposed on the inner arm surface 213 of the tweezer arm 21 along the extending direction of the tweezer arm 21.

[0044] The heat pipe 233 is arranged on the inner arm surface 213 of the tweezer arm 21, so that it is not easy for the welding operator to touch the heat pipe 233 when using the tweezers 2, thereby preventing the welding operator from being scalded by the heat pipe 233 during the use of the tweezers 2. At the same time, since the two tweezer arms 21 of the tweezers 2 are in a spaced state when not in use, and the heat pipe 233 is arranged on the inner arm surface 213 of the tweezer arm 21, the tweezer arm 21 can also play a role in protecting the heat pipe 233 to prevent the heat pipe 233 from being worn by external objects.

[0045] In other embodiments, the heat pipe 233 can also be arranged on the side surface or the outer surface of the tweezer arm 21, and the heat dissipation end 232 of the heat pipe 233 can also extend outward from the tweezer arm 21. As long as the heat pipe 233 has a certain length and the heat dissipation end 232 of the heat pipe 233 extends along the direction away from the second end 212 of the tweezer arm 21, the heat of the heat collection end 231 can be transferred to the heat dissipation end 232 for heat dissipation. This application does not make special restrictions on the specific position of the heat pipe 233 arranged on the tweezer arm 21. In addition, the heat conducting member 23 can also be arranged in the form of a heat conducting rod or a heat conducting wire. For example, one end of the heat conducting rod or the heat conducting wire can be connected to the heat absorbing member 22, and the other end can extend along the direction away from the tweezer arm 21. This application does not make special restrictions on the specific structure of the heat conducting member 23.

[0046] In some embodiments, as Figure 5 shown, the heat conducting member 23 can further include a heat dissipation liquid 234; the heat dissipation liquid 234 is filled in the heat pipe 233, and the heat dissipation liquid 234 can be used to absorb the heat of the heat collection end 231 and evaporate to form steam and flow towards the heat dissipation end 232.

[0047] When the heat collection end 231 of the heat conducting member 23 absorbs the heat transferred by the heat absorbing member 22, the temperature of the heat collection end 231 rises. The heat dissipation liquid 234 can absorb the heat of the heat collection end 231 and evaporate to form steam. The steam carries the heat and flows towards the heat dissipation end 232 for heat dissipation, so that the heat of the heat collection end 231 can be quickly dissipated to enhance the continuous heat dissipation ability of the tweezers 2. When the steam condenses at the heat dissipation end 232, the condensed heat dissipation liquid 234 can flow back to the heat collection end 231 again. Thus, the heat conducting member 23 can be recycled repeatedly to save the cost of the tweezers 2.

[0048] Among them, the heat conducting member 23 can be made of a metal material with good heat conductivity such as a copper pipe, an aluminum alloy pipe or a stainless steel pipe, and the heat dissipation liquid 234 can be made of a liquid material that is easy to evaporate such as water or alcohol. This application does not make special restrictions on the specific materials of the heat conducting member 23 and the heat dissipation liquid 234.

[0049] In some embodiments, as Figure 5As shown, the shape of the heat pipe 233 can be set as a flat tube; a groove 214 is provided on the inner arm surface 213 of the tweezer arm 21, and the heat pipe 233 can be installed in the groove 214, and one side surface of the heat pipe 233 is exposed from the groove 214.

[0050] Setting the shape of the heat pipe 233 as a flat tube structure form enables the heat pipe 233 to have a larger contact area with air, so that the heat pipe 233 can have a larger heat dissipation area. In other embodiments, the heat pipe 233 can also be set as a round tube or a rectangular tube and other structure forms, and the present application does not make special restrictions on the specific shape of the heat pipe 233.

[0051] During installation, the heat pipe 233 can be fixed in the groove 214 of the tweezer arm 21 by means of bonding, clamping or plugging. For example, the groove 214 can be set as a card slot structure, so that the heat pipe 233 can be slidably plugged into the groove 214 from the second end 212 of the tweezer arm 21, and the present application does not make special restrictions on the specific manner of fixing the heat pipe 233 on the tweezer arm 21. Since one side surface of the heat pipe 233 is exposed from the groove 214, the heat pipe 233 can directly dissipate heat to the air on the side surface exposed from the groove 214.

[0052] In some embodiments, as Figure 6 shown, the material of the heat absorbing member 22 can be a flexible heat absorbing member 22, and the heat collecting end 231 of the heat conducting member 23 can also be fixed to the second end 212 of the tweezer arm 21 through the heat absorbing member 22.

[0053] Using a flexible heat absorbing member 22, when the tweezer arm 21 clamps the pin 12, the flexible heat absorbing member 22 can deform and wrap the clamping point b, so as to ensure sufficient contact between the heat absorbing member 22 and the pin 12, so that the heat on the pin 12 can be transferred to the heat absorbing member 22 as much as possible. Among them, the material of the heat absorbing member 22 can be selected from metal mesh structures such as copper mesh or stainless steel mesh, or the material of the heat absorbing member 22 can also be selected as flexible heat conducting cloth. The present application does not make special restrictions on the specific material of the heat absorbing member 22.

[0054] In addition, the flexible heat absorbing member 22 can also bind the heat collecting end 231 of the heat conducting member 23 to the second end 212 of the tweezer arm 21. Thus, the heat absorbing member 22 can not only play a role in conducting heat between the pin 12 and the heat conducting member 23, but also the heat absorbing member 22 can play a role in fixing the heat conducting member 23, so as to improve the connection stability between the heat conducting member 23 and the tweezer arm 21. For example, the heat absorbing member 22 can be set as a sleeve structure to be sleeved on the second end 212 of the tweezer arm 21 and fix the heat collecting end 231 of the heat conducting member 23, and the present application does not make special restrictions on the specific shape of the heat absorbing member 22.

[0055] In some embodiments, as Figure 6As shown, the heat absorbing element 22 may be a metal mesh provided with meshes 220 , and the meshes 220 may be used to absorb the heat dissipation medium. The heat absorbed by the heat absorbing element 22 may also be dissipated through the heat dissipation medium.

[0056] Among them, the heat dissipation medium can be selected from materials such as alcohol or thermally conductive silicone. This application does not impose any special restrictions on the specific material of the heat dissipation medium. Before welding, the heat absorption component 22 can be dipped in some alcohol or thermally conductive silicone, and the alcohol or thermally conductive silicone can adhere to the mesh 220. When the tweezers arm 21 clamps the pin 12, the heat dissipation medium can wrap around the pin 12, so that the heat absorption component 22 can transfer the heat of welding to the heat pipe 233 for rapid heat dissipation. At the same time, when alcohol is selected as the heat dissipation medium, the volatilization of the alcohol itself will also take away part of the heat, thereby further improving the heat dissipation capacity of the tweezers 2, which is beneficial to improving the welding yield of the temperature fuse 1.

[0057] In some embodiments, as Figure 3 and Figure 7 As shown, the tweezers 2 may further include a heat sink 24 ; the first ends 211 of the two tweezer arms 21 are respectively connected to the heat sink 24 , and the heat sink 232 of the heat conductor 23 is connected to the heat sink 24 , and the heat sink 24 is used to dissipate heat on the heat sink 232 .

[0058] Therefore, by setting the heat sink 24 at the first end of the two tweezers arms 21, the heat sink 24 can not only connect the two tweezers arms 21, but also through the connection between the heat sink 24 and the heat conductor 23, the heat sink 24 can also dissipate heat for the heat dissipation end 232 of the heat conductor 23, thereby enhancing the ability of the tweezers 2 to continuously dissipate heat.

[0059] The heat sink 24 may be made of a metal such as copper, stainless steel, or aluminum alloy. Metal not only has good heat dissipation but also has high structural strength, which helps ensure the stability of the tweezers 2. Furthermore, the tweezers arm 21 and the heat sink 24 may be connected by screw threads, snap connections, pin connections, or mortise and tenon connections. This application does not impose any particular restrictions on the connection method between the tweezers arm 21 and the heat sink 24.

[0060] In some embodiments, as Figure 7 As shown, the heat sink 24 may include a connecting portion 241; the connecting portion 241 is connected to the first end 211 of the tweezers arm 21, and the heat dissipation end 232 of the heat conductor 23 is connected between the tweezers arm 21 and the connecting portion 241. A heat conducting medium 243 may be filled between the heat dissipation end 232 and the connecting portion 241, and the heat conducting medium 243 is used to transfer the heat of the heat dissipation end 232 to the connecting portion 241.

[0061] After the tweezer arm 21 is connected to the heat dissipation member 24, the heat dissipation end 232 of the heat conduction member 23 can abut between the tweezer arm 21 and the connection portion 241, so that the heat on the heat dissipation end 232 can be transferred to the connection portion 241 for heat dissipation. In addition, by filling a heat conduction medium 243 between the heat dissipation end 232 and the connection portion 241, the heat of the heat dissipation end 232 can be quickly transferred to the heat dissipation member 24 for heat dissipation. Among them, the heat conduction medium 243 can be selected from heat conduction materials such as heat conduction silica gel, heat conduction silicone grease or graphite, and the present application does not make special restrictions on the specific material of the heat conduction medium 243.

[0062] In some embodiments, as Figure 3 and Figure 7 shown, the heat dissipation member 24 may further include a plurality of heat dissipation fins 242; the plurality of heat dissipation fins 242 are connected to the connection portion 241, and the plurality of heat dissipation fins 242 are spaced apart from each other, and the heat of the connection portion 241 can be dissipated through the plurality of heat dissipation fins 242.

[0063] By providing a plurality of heat dissipation fins 242 on the connection portion 241, the heat dissipation member 24 can form a radiator structure with heat dissipation fins. The plurality of heat dissipation fins 242 can increase the heat dissipation area of the connection portion 241, so that the heat absorbed by the connection portion 241 can be quickly dissipated through the plurality of heat dissipation fins 242, thereby improving the heat dissipation capacity of the tweezers 2. According to the design of different sizes and shapes of the connection portion 241, the number and spacing of the heat dissipation fins 242 can be adjusted adaptively, and the present application does not make special restrictions on the specific parameters of the number and spacing of the heat dissipation fins 242.

[0064] In some embodiments, as Figure 3 shown, the tweezers 2 may further include a conductive member 25; the conductive member 25 is disposed on the outer surface of the tweezer arm 21, and the conductive member 25 can cover the touch portion of the tweezer arm 21.

[0065] During the process of welding the temperature fuse 1, it is easy to generate static electricity on the tweezers 2. By providing the conductive member 25 on the outer surface of the tweezer arm 21, the welder can ground the static electricity bracelet. In this way, the static electricity on the tweezers 2 can be released through the conductive member 25 and the static electricity bracelet, thereby avoiding the static electricity generated during welding from damaging the temperature fuse 1 and improving the welding yield.

[0066] Among them, the material of the tweezer arm 21 can be selected from insulating and heat-insulating plastics, rubbers or wood materials to avoid the tweezers 2 from getting too hot and scalding hands. The material of the conductive member 25 can be selected from materials with good electrical conductivity such as metal copper sheets, iron sheets or stainless steel sheets, and the present application does not make special restrictions on the specific materials of the tweezer arm 21 and the conductive member 25.

[0067] The above uses specific examples to elaborate on the present utility model, which is only for helping to understand the present utility model and is not intended to limit the present utility model. For those skilled in the technical field to which the present utility model pertains, based on the idea of the present utility model, several simple deductions, deformations or substitutions can also be made.
