In the cable nose crimping device, a crimping mechanism 20 is arranged on a frame 10, the crimping mechanism 20 is provided with a movable wire pressing groove 21 and a first through hole 22, the wire pressing groove 21 can accommodate a cable 1 and a wire nose 3, the first through hole 22 penetrates into the wire pressing groove 21 from one end of the crimping mechanism 20, and the crimping mechanism 20 is used for crimping the cable 1 and the wire nose 3; a heating mechanism 40 is provided on the housing 10 at one side of the crimping mechanism 20, the heating mechanism 40 being used to heat the solder paste in the wire nose 3.

It should be noted that, the side wall of the insertion end 5 of the wire nose 3 is provided with a through hole, and the through hole is communicated with the first through hole 22 and the interior of the insertion end 5 of the wire nose 3, so it is conceivable that the heat source emitted by the heating mechanism 40 can enter the interior of the wire nose 3 through the first through hole 22 and the through hole on the wire nose 3, and further, the solder can be directly heated, the heating efficiency can be improved, and meanwhile, the sufficient reaction of the solder can be ensured.

Therefore, the cable wire nose crimping device provided by the embodiment of the invention has at least the following beneficial effects: the cable nose crimping device provided by the embodiment of the invention is applied to a hot-pressing process, the plugging end 5 of the cable 1 is plugged into the cable nose 3, the soldering tin material in the wiring end 4 of the cable nose 3 is heated by the heating mechanism 40, and simultaneously the crimping of the cable 1 and the cable nose 3 is finished by matching with the extrusion action of the crimping mechanism 20.

In yet other embodiments of the present invention, the portable mechanism is returned to its original position, secured to the housing, and the cable is placed on the housing to perform a cable nose hot press operation, and the cable nose crimping apparatus may further include a clamping mechanism 50. In contrast to the cable nose crimping apparatus without the clamping mechanism 50, the clamping mechanism 50 is provided on the housing 10 below the crimping mechanism 20, the clamping mechanism 50 comprising a movable jaw assembly 51, the jaw assembly 51 being adapted to grip the cable nose 3. Therefore, it is conceivable that the clamping mechanism 50 may be used for initial fixation of the wire nose 3.

Referring to fig. 2, 5, and 6-7, in some embodiments of the invention, the crimping mechanism 20 includes: a first driving member 23, a mounting portion 24, and a movable portion 25. The first driving member 23 is disposed on the frame 10, and the first driving member 23 has an output end; the mounting part 24 is movably arranged at one end of the first driving piece 23, the output end of the first driving piece 23 is arranged at one end of the mounting part 24 in a penetrating manner, the mounting part 24 is provided with the wire pressing groove 21, and the first through hole 22 penetrates into the wire pressing groove 21 from one end of the mounting part 24; the movable part 25 is arranged at the output end of the first driving piece 23, and the first driving piece 23 drives the movable part 25 to move in the wire pressing groove 21; the wire groove 21 is provided with a first wire pressing portion 211 and a second wire pressing portion 212 on two sides, the second wire pressing portion 212 is arranged on the mounting portion 24, the first wire pressing portion 211 is arranged on the movable portion 25, and the first wire pressing portion 211 and the second wire pressing portion 212 are arranged oppositely.

Specifically, the first driving member 23 drives the movable portion 25, so as to drive the first wire pressing portion 211 on the movable portion 25 to move, and since the output end of the first driving member 23 is disposed at one end of the mounting portion 24 in a penetrating manner, the movable portion 25 is disposed at one end of the mounting portion 24, that is, the movable portion 25 is disposed at one side of the wire pressing groove 21, and slides in the wire pressing groove 21 along the driving direction of the first driving member 23, so that the first wire pressing portion 211 can be far away from or near the second wire pressing portion 212 disposed opposite to the first wire pressing portion. When the first wire pressing part 211 is close to and attached to the outer side wall of the wire nose 3, the second wire pressing part 212 contacts with the outer side wall of the attached wire nose 3 at the same time, so that the second wire pressing part 212 on the other side of the wire pressing groove 21 can be matched to press the inserting end 5 of the wire nose 3; when the first pressing portion 211 is far away from the second pressing portion 212, the crimped cable 1 and the wire nose 3 can be taken out from the pressing groove 21.

It will be appreciated that the fixed block 26 and the movable block 27 are detachably disposed in the wire pressing groove 21, and therefore, the fixed block 26 and the movable block 27 are replaceable. It is conceivable that the first wire pressing portion 211 and the second wire pressing portion 212 are damaged by the high temperature during the heating and pressure welding process, and the detachable and replaceable fixed block 26 and the movable block 27 are respectively added on the second wire pressing portion 212 and the first wire pressing portion 211, so that the whole pressure welding mechanism 20 is prevented from being replaced due to the damage of the mounting portion 24 by the high temperature, and the maintenance cost is reduced. While the second through hole 261 on the fixing block 26 corresponds to the first through hole 22 in position, it is conceivable that the heat source of the heating mechanism 40 sequentially passes through the first through hole 22 and the second through hole 261, and finally directly heats the wire nose 3 in the wire pressing groove 21 and the solder material therein.

Still further, in some embodiments of the present invention, the fixed block 26 and the movable block 27 include contact surfaces 28, the contact surfaces 28 abut against the outer side of the wire nose 3, and the contact surfaces 28 are adapted to the outer side of the wire nose 3. Therefore, it is conceivable that the contact surfaces 28 of the fixed block 26 and the movable block 27 that contact the outside of the wire nose may be arc-shaped contact surfaces 28, or may be polygonal-prism-shaped side surfaces, or the like, and both of the contact surfaces 28 may effectively press the wire nose 3. In addition, since the fixed block 26 and the movable block 27 are both detachably arranged, the fixed block 26 and the movable block 27 of the contact surface 28 with different shapes can be replaced, and the fixed block 26 and the movable block 27 of the contact surface 28 with different sizes can be replaced, so that the crimping mechanism 20 is suitable for crimping cables 1 and wire noses 3 with different sizes. Specifically, the wire pressing range is wide, namely the section of the compressible wire is from 10 square millimeters to 240 square millimeters, and the range covers most wire types required by the market, so that the applicability is high. Meanwhile, the full-automatic melt-pressing all-in-one machine is high in welding efficiency, labor efficiency is greatly improved, welding of 120 square millimeter wires only needs less than 30 seconds, wiring quality can be greatly improved, and labor cost and time cost can be reduced.

Referring to fig. 1, 3 and 5, in some embodiments of the invention, the heating mechanism 40 includes a laser generator and a laser emitter 41. A laser generator (not shown) is provided in the housing 10; the laser transmitter 41 is disposed on the frame 10 at one side of the mounting portion 24, the laser transmitter 41 is connected to the laser generator, and the laser transmitting direction of the laser transmitter 41 coincides with the axis of the first through hole 22. Therefore, the high-energy rays emitted by the laser emitter 41 pass through the first through hole 22 on the crimping mechanism 20 and then enter the wire pressing groove 21, pass through the second through hole 261 on the fixed block 26 and reach the through hole on the wire nose 3, and then irradiate the soldering tin material inside the wire nose 3 and the wire core of the cable 1, so that the soldering tin material and the wire core of the cable 1 can be heated.

It should be emphasized that, in other embodiments, the heating mechanism 40 may be an ultrasonic heating method, an electric induction heating method, an arc heat release heating method, or a plasma arc heat release heating method, and the fixed blocks 26 and the movable blocks 27 in the corresponding press-bonding mechanism 20 may be connected to the heating mechanism 40, and the purpose of heating the solder material in the wire nose 3 and the wire core of the cable 1 may be achieved by using the heating mechanism 40, that is, the fixed blocks 26 and the movable blocks 27, so that the heating mechanism 40 may not be specifically limited in this embodiment, and the wire nose 3, the solder material, and the wire core may be heated.

Referring to fig. 10-11, in some embodiments of the present invention, the crimping mechanism 20 and the heating mechanism 40 are slidably coupled to the frame 10 via the mounting block 11. That is, a chute is provided on the frame 10, and the chute is used for sliding the mounting block 11, so that the mounting block 11 can be removed, and the crimping mechanism 20 and the heating mechanism 40 can be removed for use in a working scene of field crimping.

It is conceivable that the mounting block 11, when mounted on the frame 10, can be used in a working scenario where the cable 1 and the wire nose 3 are pressed in batches. For example, the crimping device of the wire nose 3 of the cable 1 may further include a feeding mechanism 60 as shown in fig. 1 to 4, the feeding mechanism 60 is disposed on the rack 10 and located below the crimping mechanism 20, and the feeding mechanism 60 includes: a conveyor belt 61 and a mounting seat 62, the conveyor belt 61 is arranged on one side of the frame 10, one end of the conveyor belt 61 is positioned below the clamping jaw assembly 51, and the conveyor belt 61 is used for conveying the nose 3; the mounting seat 62 is rotatably arranged on the conveyor belt 61, the mounting seat 62 is provided with a mounting groove 621, the mounting groove 621 is used for mounting the wiring terminal 4 of the wire nose, and the rotation center of the mounting seat 62 is coincident with the axis of the plug-in end 5 of the wire nose 3.

It is emphasized that the movable mounting portion 24 is movably provided at the output end of the first driving member 23, and when the feeding mechanism 60 feeds the wire nose 3 into the crimping mechanism 20, the movable mounting portion 24 moves rightward by a certain distance to align the notch of the wire crimping slot 21 with the direction in which the wire nose 3 is fed, so that the wire nose 3 enters the wire crimping slot 21.

It should be further noted that, when the connection end 2 of the cable 1 is connected to the connection end 5 of the wire nose 3, the wire nose 3 in the mounting groove 621 can be rotated by the rotating mounting seat 62 before the heating mechanism 40 heats and the crimping mechanism 20 crimps; meanwhile, as the rotation center of the mounting seat 62 coincides with the axis of the inserting end 5 of the wire nose 3, the rotation center of the wire nose 3 coincides with the wire core of the cable 1, the solder in the wire nose 3 is moved in the rotation process of the wire nose 3, so that the solder can be uniformly coated on the wire core of the cable 1, the solder is prevented from being unevenly distributed due to the fact that the solder is hung on the wall of the solder injection port 31 arranged on one side of the wire nose 3 when the solder is sprayed out, the contact between the wire core of the cable 1 and the inner side wall of the wire nose 3 is better, the contact area 28 is increased, and meanwhile, the connection tightness is enhanced, namely, the connection stability between the cable 1 and the wire nose 3 is enhanced.

When the crimping work is completed between the cable 1 and the wire nose 3, the wire nose 3 is taken out of the mounting groove 621 of the mounting seat 62 by taking out the cable 1, and then the next mounting seat 62 is conveyed to the lower part of the crimping mechanism 20 by the conveyor 61.

In some embodiments of the present invention, the cable nose crimping device further includes a temperature measuring mechanism (not shown) provided on the frame 10, the temperature measuring mechanism being configured to detect a heating temperature of the heating mechanism 40. The temperature measuring mechanism can comprise two temperature sensors, such as non-contact infrared temperature sensors, wherein one temperature sensor can be used for measuring the temperature of the plug-in end 5 of the wire nose 3, so that the temperature in the welding process can be conveniently controlled, insufficient melting of soldering tin in the wire nose 3 can be avoided, and the welding quality is influenced; and the other temperature sensor can measure the temperature of the insulating layer near one side of the wire nose 3 so as to control the temperature and time of the insulating layer and avoid the insulating layer from being damaged by long-time overheat in the welding process.

Specifically, the output end of the second sliding component 54 is provided with the clamping jaw component 51, and the output direction of the output end of the second sliding component 54 is the left-right direction, so that the clamping jaw component 51 is driven by the second sliding component 54 to be far away from or near to the upper side of the feeding mechanism 60, so it can be understood that the second sliding component 54 can drive the clamping jaw component 51 to avoid the transmission of the wire nose 3 and to be close to the clamping and fixing wire nose 3. The first sliding component 53 is disposed on the mounting plate 521 at one side of the mounting box 52, and the sliding direction of the first sliding component 53 is vertical, and the second sliding component 54 is disposed on the output end of the first sliding component 53, so that the first sliding component 53 can drive the second sliding component 54 to drive the clamping jaw component 51 to clamp the wire nose 3, and lift the wire nose 3 upward from the mounting groove 621. Furthermore, the second driving piece 522 is arranged in the mounting box 52, the second driving piece 522 drives the inner side of the mounting plate 521 to act on, so that the mounting plate 521 turns around by taking one end hinged on the mounting box 52 as a turning center, the first sliding component 53 mounted on the mounting plate 521 is inclined, the second sliding component 54 is driven to lift upwards, namely, the clamping jaw component 51 on the output end of the second sliding component 54 is lifted, finally, the wire nose 3 in the clamping jaw component 51 is inclined by a certain angle, the angle is adapted to the tin injection port 31 of the tin injection mechanism 30, the tin injection direction of the tin injection port 31 is coincided with the central axis of the inserting end 5 of the wire nose 3, thereby being more beneficial to the tin injection mechanism 30 to inject the soldering tin, reducing the possibility of hanging the soldering tin, being convenient for the periphery of the inserting end 2 of the soldering tin hanging wall, being immersed in the soldering tin material, thereby enabling the contact between the wire core of the wire cable 1 and the inner side wall of the wire nose 3 to be better, increasing the contact area 28, and simultaneously, the tightness of the connection degree between the wire 1 and the wire nose 3 to be enhanced.

Then, the second driving mechanism stops outputting the mounting plate 521, and the mounting plate 521 returns to the left side of the mounting box 52 in the original path under the action of gravity, so that the first sliding assembly 53 is restored to the initial state and the vertical state, and the second sliding mechanism can also be restored to the horizontal state, and the wire nose 3 in the clamping jaw assembly 51 is also restored to the vertical state.

In the above embodiment, the first sliding component 53 and the second sliding component 54 may be a screw structure, a translation mechanism of a rack and pinion, a pushing mechanism such as an air cylinder or a hydraulic cylinder, etc., and the embodiment of the present invention is not particularly limited, and the second sliding mechanism may be driven to move up and down, and the clamping jaw component 51 may be driven to move horizontally.

And the second driving member 522 may be provided with a cam structure that, when the cam portion of the cam structure abuts against the driving inclined surface 5211 on the mounting plate 521, the cam structure lifts up the mounting plate 521 so that the mounting plate 521 is turned counterclockwise, thereby enabling the inclined placement of the wire nose 3 for facilitating the tin injection of the tin injection mechanism 30. When the cam part of the cam structure is separated from the driving inclined plane 5211 of the mounting plate 521, the mounting plate 521 can be slowly reset under the action of gravity in cooperation with the rotation of the cam structure, so that the wire nose 3 is finally restored to the initial state, namely the vertical state, and the wire nose is convenient for plugging the cable 1.

It should be noted that, the tilting time of the wire nose 3 is the tin injection time of the tin injection mechanism 30, so according to the crimping requirements of different wire noses 3 and different cables 1, there are different materials of the soldering tin material and different tin injection requirements of different usage amounts, so the tilting time of the wire nose 3 is different, namely, the angles of the swing angles of the cams of different second driving members 522 can be set, the larger the swing angle of the cams is, the longer the tilting time of the wire nose 3 is, and the use scene with more tin injection usage amount is satisfied; and conversely, the smaller the swing angle of the cam is, the shorter the inclination time of the wire nose 3 is, so that the use scene with less tin injection amount is satisfied.

It should be further noted that, after the cam portion of the cam mechanism of the second driving member 522 is separated from the driving interface, that is, between the adjacent two cams abutting against the driving inclined plane 5211, the time for inserting the cable 1 into the inserting end 5 of the wire nose 3, the time for heating the wire nose 3 by the heating mechanism 40, the time for conveying the wire nose 3, the actuation time of the first sliding component 53 and the second sliding component 54, and the like are included, so that the mechanisms are highly matched, so that the crimping process is completely and smoothly operated, and the crimping efficiency between the cable 1 and the wire nose 3 can be improved.

The technician can manually press the pressing end 512 and compress the elastic member 513, so that the clamping end 511 is opened under the action of the hinge point to facilitate clamping the wire nose 3, and after the pressing end 512 is loosened, the clamping end 511 can be reset under the action of the elastic member 513 and clamp the wire nose 3 under the action of the elastic force. The elastic member 513 may be a spring or a rubber member, etc., and is not particularly limited in this embodiment.
