Description

Coaxial cable automatic supply tinning system {COAXIAL CABLE AUTOMATIC SUPPLY TINNING SYSTEM}

The present invention relates to a coaxial cable automatic supply tinning system, and more particularly, in the tinning process, which is a process of braiding the end of a coaxial cable, automatically supplying a coaxial cable, but rotating the coaxial cable during the tinning process It relates to a coaxial cable automatic supply tinning system that is provided so that the ends of the cable can be soldered evenly.

In recent years, research on a connected car configured to support vehicle safety, convenience improvement, and infotainment service by connecting various electronic devices inside a vehicle and an external network through wireless communication has been actively conducted.

The main systems constituting the connected car transmit signals mainly using coaxial cables inside the vehicle, and as the demand for infotainment services increases, the bandwidth increases, durability, and information reliability are increased. There is a demand for higher performance of cables.

As described above, the coaxial cable applied to the vehicle is generally coated by soldering the metal terminal at the end of the coaxial cable in order to be connected to the electronic circuit board inside the vehicle. That is, a soldering method is widely used as a method for connecting a coaxial cable, which is a metal wire, to an electronic component such as a printed circuit board.

Therefore, in order to facilitate the connection work between the coaxial cable and the printed circuit board, a process of pre-coating the metal terminal of the coaxial cable with lead is required.

In the process of pre-coating lead, there is a dipping process, which is a method of stripping the insulating material surrounding the end of the coaxial cable and coating the metal terminal with high-temperature liquid lead.

The dipping process is a method of coating lead by vertically descending and immersing the object to be dipping into high-temperature liquid lead contained in a container.

When this dipping process is continuously performed for mass production of a coaxial cable, the non-uniformity of excessively dipping or insufficiently dipping lead in a portion may occur depending on the shape of the end portion of the coaxial cable.

When lead is coated non-uniformly as described above, a problem in connectivity with the printed circuit board may be deteriorated due to an increase in material cost due to excessive use of lead and a non-uniform lead coating.

In order to solve this problem, a device capable of uniformly coating lead by supplying air to a coaxial cable or the like using an air nozzle has been disclosed in Korean Patent Registration No. 10-1151262.

The device disclosed in Korean Patent Registration No. 10-1151262 has an inlet and outlet on both sides of a solder tank containing high-temperature liquid lead so that the insulated metal wire passes through the liquid lead. The device is configured so that only the lead is coated, and external air is introduced using the air nozzle coupled to the outlet so that the lead is spread evenly and dipping.

A device such as a wire dipping device disclosed in Korean Patent Registration No. 10-1151262 may be useful when the insulating material does not melt or deform even with high-temperature liquid lead, but an insulating material having a melting point similar to or lower than the temperature of liquid lead. When applied to a wire composed of

In addition, like the coaxial cable 1 shown in FIG. 1 , even in the case of a high-frequency cable consisting of two terminals: a core wire 1a provided as a conductor at the center and a braid 1b provided as an external conductor, the conventional When the dipping process is used, the core wire 1a, the braid 1b, and the insulator 1c are simultaneously immersed in the high-temperature liquid lead, which may cause a problem in which the insulator 1c is melted.

Therefore, a coaxial cable tinning device for independently soldering the core wire and braid of a coaxial cable has been proposed in Korean Patent Registration No. 10-1905666. The coaxial cable tinning device disclosed in Korean Patent Registration No. 10-1905666 has an effect of preventing damage to the insulator by high-temperature liquid lead.

In other words, the coaxial cable tinning device disclosed in Korean Patent Registration No. 10-1905666 does not vertically immerse the coaxial cable in high-temperature liquid lead, but inserts the coaxial cable into the continuously descending liquid lead in the rotational direction. It is a device that allows the solder to be coated only on the two terminals by controlling the position where the top solder falls and the thickness of the liquid solder.

As such, the coaxial cable tinning device disclosed in Korean Patent Registration No. 10-1905666 has the advantage of minimizing damage to the insulator and independently soldering two metal terminals.

However, although damage to the insulator is minimized in the above manner, there is a problem in that the lead is not evenly coated on the two terminals corresponding to the core wire and the braid, and there is a problem in that a portion is coated with lead excessively or insufficiently.

In addition, there was a problem in that the coaxial cable was manually supplied and aligned in the tinning process, resulting in decreased productivity, reduced quality consistency, and direct exposure of workers to harmful processes.

Since it is a system in which tinning is performed, for convenience of description of the automatic coaxial cable supply tinning system 10 according to an embodiment of the present invention, the process will be described in a schematic sequence.

The coaxial cable automatic feeding device 200 is provided with a coaxial cable lead-in hopper (hopper, 210) into which the coaxial cable (1) is introduced, and automatically aligns the coaxial cable (1) introduced into the hopper (210) and supplies it. In other words, the automatic coaxial cable feeder 200 introduces the coaxial cable 1 that requires soldering of the termination through the hopper 210 and automatically aligns the introduced coaxial cable 1 .

The coaxial cable automatic feeder 200 is connected to the hopper 210 and aligns the coaxial cable 1 by vibrating the vibrating feeder 220 and the side end opposite to the hopper 210 side of the vibrating feeder 220 and a vertical alignment unit 230 for vertically aligning the coaxial cable by having an alignment gradient 231 of a downwardly inclined shape. The alignment gradient 231 according to the present embodiment is formed in a V-shaped cross-section, so that the coaxial cables 1 can be automatically aligned one by one.

The coaxial cable vacuum adsorption transfer device 300 is connected to the coaxial cable automatic supply device 200 and transports the coaxial cable 1 by vacuum adsorption, the first vacuum adsorption transfer unit 310 and the conveyor alignment unit 320 and a second vacuum adsorption transfer unit 330 .

The first vacuum adsorption transfer unit 310 is connected to the automatic coaxial cable supply device 200 to vacuum-adsorb the coaxial cable 1 and transport it.

In addition, the conveyor alignment unit 320 is provided below one end of the first vacuum adsorption transfer unit 310 to align the ends of the plurality of coaxial cables 1 received from the first vacuum adsorption transfer unit 310. Zero alignment is performed. proceed In other words, the conveyor alignment unit 320 is provided to intersect the coaxial cable 1 transport direction, which is the direction in which the coaxial cable 1 is transported in the first vacuum adsorption transport 310 , and terminates the plurality of coaxial cables 1 .

In the coaxial cable rotary tinning device 100, a coating process of coating the terminal end of the coaxial cable 1 with lead while rotating the coaxial cable 1 provided with the flux coating device 400 adjacent to the flux coating device 400 It is a device that does

The coaxial cable rotary tinning device 100 includes a lead tank 110 in which liquid lead is stored, a pump P transporting liquid lead stored in the lead tank 110, and a liquid lead transported by the pump P. The discharge unit 120, the casing 130, the adjusting unit 140, and the coaxial cable rotating unit 150, which are received and discharged to the lead tank 110, are spaced apart from the lead tank 110 to the upper part by a predetermined interval. And, it may include a tinning jig 160 for supporting the coaxial cable rotating unit 150.

The solder tank 110 forms a predetermined space in which liquid lead (hereinafter, referred to as 'lead water') can be stored, and a heating means (H) for heating the solder water or maintaining the temperature of the solder water is provided at the bottom. installed.

The pump (P) serves to transport the lead water stored in the lead tank 110 to the upper part, and may be accommodated in the casing 130 provided on one side in the longitudinal direction of the lead tank 110 . For reference, a known pump device to which a motor and an impeller are applied may be used as the pump P, and various other pump devices used in other general industrial fields may be used.

An inlet 131 communicatively connected to the space formed in the lead tank 110 is provided at the lower end of the casing 130, and an outlet 132 through which lead water transported by the pump P is discharged is provided at the upper end thereof.

The discharge unit 120 receives the solder discharged from the outlet 132 of the casing 130 and discharges it to the solder tank 110, and the solder discharged from the discharge unit 120 is discharged in two directions so that the coaxial cable ( The core wire 1a and the insulator 1c of 1) may be coated with a predetermined time difference, respectively.

The discharge unit 120 includes a supporting member 121 that receives the lead transported by the pump P, and a first discharge port 122 and a second discharge port 123 provided on the bottom surface of the supporting member 121. may include

The support member 121 forms a predetermined space for accommodating the solder discharged from the outlet 132 of the casing 130 , and may be detachably coupled to the outlet 132 .

A configuration in which the support member 121 is detachably coupled to the outlet 132 of the casing 130 may be applied to various known configurations. For example, a guide rail 133 having a 'C'-shaped cross section into which the longitudinal end of the support member 121 can be inserted is installed on the inner surface of the casing 130 that partitions the outlet 132 to provide the support. The longitudinal end of the member 121 may be detachably coupled to the outlet 132 of the casing 130 .

The first discharge port 122 and the second discharge port 123 are constant to each other along the longitudinal direction (the X direction shown in FIG. 3 ) and the width direction (the arrow Y direction shown in FIG. 3 ) of the support member 121 . It may be formed on the bottom surface of the support member 121 in a spaced apart state.

In addition, the lead water introduced into the support member 121 through the outlet 132 of the casing 130 may be discharged to the lead tank 110 through the first outlet 122 and the second outlet 123 , respectively.

The first discharge port 122 and the second discharge port 123 may be spaced apart from each other at a predetermined distance along the longitudinal direction and the width direction of the supporting member 121 to be formed on the bottom surface of the supporting member 121 .

The reason why the first discharge port 122 and the second discharge port 123 are spaced apart from each other by a predetermined distance along the width direction of the support member 121 is, for example, preferentially covering the braid 1b of the coaxial cable 1 with solder. This is to cover the core wire (1a) of the coaxial cable (1) with lead after the That is, the braid 1b and the core wire 1a of the coaxial cable 1 are sequentially coated with solder.

And, the reason that the first outlet 122 and the second outlet 123 are spaced apart from each other by a predetermined distance along the longitudinal direction of the support member 121 is between the core wire 1a of the coaxial cable 1 and the braid 1b. This is to prevent the insulator 1c from being coated with lead. That is, the first outlet 122 and the second outlet 123 are spaced apart as much as the distance occupied by the insulator 1c of the coaxial cable 1 to discharge the solder only at the portion where the core wire 1a and the braid 1b are formed. am.

Accordingly, as shown in FIG. 2 , the coaxial cable 1 is disposed in a direction parallel to the longitudinal direction of the support member 121 and then the support member in the space formed between the lead tank 110 and the support member 121 . When passing along the width direction of (121), the braid (1b) of the coaxial cable (1) may be primarily covered by the solder discharged from the second outlet (123).

Then, the core wire 1a of the coaxial cable 1 may be secondaryly covered by the solder discharged from the first outlet 122 .

Accordingly, it is possible to coat the core wire 1a and the braid 1b of the coaxial cable 1 with solder in a single process of passing the end of the coaxial cable 1 through the lower portion of the support member 121 .

For reference, the width of the first outlet 122 or the second outlet 123 in order to uniformly coat the entire outer circumferential surface (the entire circumferential edge) of the core wire 1a and the braid 1b having a circular cross section. It is preferable that the direction lengths (L1, L2)) are 8 to 12 times larger than the circumferential length of the core wire 1a or the braid 1b of the coaxial cable 1 to be covered. For this reason, when the time for the core wire (1a) or the braid (1b) to pass through the inside of the braid for the coating of the lead material is considered, the width direction length L1 of the first outlet port 122 or the second outlet port 123 (L1, L2)) is preferably 8 to 12 times larger than the circumferential length of the core wire 1a or braid 1b of the coaxial cable 1 to be covered. It is most preferable to form it in about 10 times the size. That is, when the width direction length (L1, L2) of the first discharge port 122 or the second discharge port 123 is less than 8 times the circumferential length of the core wire 1a or the braid 1b, the core wire 1a) However, it is difficult to coat the entire outer circumferential surface of the braid 1b, and when it exceeds 12 times, the working time becomes too long, and the desired mass production rate cannot be maintained.

For example, when the circumferential length of the core wire 1a of the coaxial cable 1 is 157 mm, the width direction length L1 of the first outlet 122 must be formed to be about 157 mm so that the solder is uniformly applied to the entire outer circumferential surface of the core wire 1a. can be covered. In addition, when the circumferential length of the braid 1b of the coaxial cable 1 is 942 mm, the width direction length L2 of the second outlet 123 must be formed to be about 942 mm so that the braid is uniformly applied to the entire outer circumferential surface of the braid 1b. can be covered.

Meanwhile, the discharge unit 120 may further include an adjustment unit 140 for adjusting the area of the first discharge port 122 or the second discharge port 123 formed in the support member 121 .

The adjusting unit 140 allows the areas of the first outlet 122 and the second outlet 123 to be adjusted corresponding to the lengths of the core wire 1a and the braid 1b of the coaxial cable 1 . That is, the adjusting unit 140 is compatible with the core wire 1a and the braid 1b of the coaxial cable 1 having various specifications so that the tinning device 100 according to an embodiment of the present invention can be coated with solder. serves to make

The adjusting unit 140 is provided along the longitudinal direction of the support member 121 and is moved along the longitudinal direction of the guide plate 141 and the guide plate 141 having scales 141a on the upper surface of the first outlet 122 . ) or a cover unit 143 for adjusting the area of the second outlet 123 may be included.

The guide plate 141 is provided along the longitudinal direction of the supporting member 121 in a state disposed on the upper portion of the supporting member 121 , and one longitudinal end thereof is connected to the other side in the longitudinal direction of the supporting member 121 and The other end extends to one side in the longitudinal direction of the support member 121 .

The cover unit 143 may be provided on a bottom surface portion of the support member 121 on which the first discharge port 122 is formed and on a bottom surface portion of the support member 121 on which the second discharge hole 123 is formed.

In addition, the cover unit 143 is provided on the bottom surface of the support member 121 to block a part of the area of the first or second outlets 122 or 123. A fixed cover 143a, and a fixed cover 143a.

The fixing cover 143a may be fixedly mounted on the bottom surface of the support member 121 to block a portion of an area formed by the first discharge port 122 or the second discharge port 123 .

The fixing cover 143a has a width direction length greater than the width direction length L1 of the first discharge port 122 or the width direction length L2 of the second discharge port 123 , and the bottom surface of the support member 121 . It may be fixedly mounted via a fastening means not shown in FIG. 1 to block a portion of an area formed by the first or second outlets 122 or 123 .

The movable cover 143b also has a width direction length greater than the width direction length L1 of the first outlet 122 or the width direction length L2 of the second outlet 123, and is formed by the fixed cover 143a. An area of the first discharge port 122 or the second discharge port 123 that is not blocked may be blocked. That is, the movable cover 143b may be moved along the longitudinal direction of the support member 121 to block the area of the first discharge port 122 or the second discharge port 123 that is not blocked by the fixed cover 143a. there is.

When the moving cover 143b is moved in the direction in which the fixed cover 143a is disposed, the area of the first outlet 122 or the second outlet 123 is reduced, and, conversely, moves in the opposite direction in which the fixed cover 143a is disposed. In this case, the area of the first discharge port 122 or the second discharge port 123 may increase. And, one side of the movable cover (143b) may be provided with a handle portion 144 that the operator can grip by hand.

Accordingly, the operator can move the movable cover 143b while holding the handle 144 in the direction in which the fixed cover 143a is disposed or in the opposite direction.

Here, the first outlet 122 or the second outlet 123 whose area is variable by the adjusting unit 140 is a core wire 1a or an insulator 1c having various lengths according to the standard of the coaxial cable 1 . To be compatible with the , a relatively larger area than the area of the first or second outlets 122 or 123 may be formed.

In addition, a seating groove 145 in which the movable cover 143b and the fixed cover 143a are inserted and seated may be provided on the bottom surface of the support member 121 .

The seating groove 145 is formed on the bottom surface of the support member 121 while having an area larger than the area formed by the first or second discharge ports 122 or 123, and the area is moved with the fixing cover 143a. The cover (143b) has a size that can be accommodated.

Accordingly, the movable cover 143b may be moved in the direction in which the fixed cover 143b is disposed or in the opposite direction while being seated in the seating groove 145 .

For example, when the length of the core wire 1a of the coaxial cable 1 to be covered is longer than the length of the core wire 1a of the coaxial cable 1 that was previously performed in the covering process, the area of the first outlet 122 is By moving the blocking moving cover (143b) in the opposite direction in which the fixed cover (143a) is disposed, it is possible to increase the spacing between the fixed cover (143a) and the moving cover (143b). Then, the area of the first discharge port 122 that was blocked by the fixed cover 143a and the movable cover 143b is further opened to correspond to the increased length of the core wire 1a.

In addition, when the length of the braid (1b) of the coaxial cable (1) to be covered is shorter than the length of the braid (1b) of the coaxial cable (1) performed in the existing coating process, the area of the second outlet (123) is By moving the blocking moving cover (143b) in the direction in which the fixed cover (143b) is arranged, it is possible to reduce the spacing between the fixed cover (143a) and the moving cover (143b).
