Description

Technical Field

[0001] The utility model relates to the field of wire material processing, in particular to a double-head terminal soldering machine. Background Art

[0002] Wire processing generally includes wire tinning and wire terminal making. Existing tinning machines mainly include single-head tinning machines, double-head tinning machines, and tinning machines with one end tinning and the other end terminal or plug. Single-head tinning machines are those that need to be tinned on one side of the wire. Then the wire only needs to be cut, stripped, fluxed, and tinned to complete the process of tinning the wire, as in patent CN105186263B. For double-head tinning machines, both sides of the wire need to be cut, stripped, fluxed, and tinned, as in patents CN210817841U and CN103996958B. The terminal machine has one end that is tinned and the other end that is terminal-bonded, and the wire feeding mechanism feeds the wire in horizontally, and the wire taking mechanism that moves horizontally clamps the wire to the wire cutting mechanism for cutting and stripping. After one end of the wire is stripped, the first moving mechanism drives the wire feeding mechanism to move to the terminal bonding mechanism position to perform terminal bonding on the wire head. After the terminal bonding process is completed, the moving mechanism drives the wire feeding mechanism to move back to the horizontal production line, corresponding to the wire cutting mechanism and the wire taking mechanism. Then the wire taking mechanism clamps the terminal bonding end of the wire with the terminal, pulls the wire through the wire cutting mechanism, and the wire cutting mechanism performs wire cutting again. The wire with the terminal is cut off and the other end is stripped, and the wire clamped on the wire feeding mechanism is moved by the moving mechanism to the terminal bonding mechanism for terminal bonding again, and the cycle repeats. The wire with the terminal is clamped by the tinning mechanism, and the other end of the stripped wire is subjected to flux application and tinning operations. Finally, the wire that has completed the tinning operation is clamped and discharged by the unloading mechanism.

[0003] In the existing wire processing, there is also a demand for installing terminals at both ends of the wire, so a double-end terminal crimping machine is developed, such as patent CN220138916U. Since tinning and terminal crimping are both wire processing businesses, how to combine tinning and double-end terminal crimping functions into the same device is a technical problem to be solved by the utility model.

[0031] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Reference Figures 1 to 8 , an embodiment of the double-head terminal soldering machine of the utility model is proposed:

[0033] A double-end terminal soldering machine comprises a frame, a wire feeding mechanism 1, a wire cutting and stripping mechanism 3, a tinning mechanism 4, and a wire taking mechanism 5 which are sequentially arranged in the length direction of the frame, and a moving mechanism 2, a first terminal-cutting mechanism 6, a wire moving mechanism 8, and a second terminal-cutting mechanism 7 which are arranged in the width direction of the frame.

[0034] The wire feeding mechanism 1 is arranged on the moving mechanism 2, and the moving mechanism 2 drives the wire feeding mechanism 1 to move along the length direction and the width direction of the frame. The moving mechanism is a mechanism that can move in the length direction and the width direction, and is a mechanical structure commonly used in the prior art.

[0035] Specifically, the moving mechanism 2 includes a third sliding track arranged to move along the width direction of the frame and a third screw connected to the third motor, the third sliding track and the first screw are arranged in parallel, and the third sliding track is located on both sides of the third screw. The moving mechanism also includes a moving bracket slidably mounted on the third sliding track through a slider, the moving bracket is transmission-connected to the third screw through a third nut, and under the control of the third motor, the moving bracket realizes movement on the third sliding track through a transmission mechanism composed of the third nut and the third screw.

[0036] The movable bracket is provided with a fourth sliding rail arranged along the length direction of the frame and a fourth screw rod connected to the fourth motor. The fourth sliding rail and the fourth screw rod are arranged in parallel, and the fourth sliding rail is located on both sides of the fourth screw rod. The wire feeding mechanism 1 is slidably connected to the fourth sliding rail through a slider, and is transmission-connected to the fourth screw rod through a fourth nut. Under the control of the fourth motor, the wire feeding mechanism 1 realizes movement on the fourth sliding rail through a transmission mechanism composed of a fourth nut and a fourth screw rod, and realizes movement on the fourth sliding rail through a transmission mechanism composed of a fourth nut and a fourth screw rod.

[0037] The wire taking mechanism 5 moves along the length direction of the frame, including a track arranged along the length direction of the frame and a mechanical gripper slidably arranged on the track, and the mechanical gripper is driven by a power source to slide on the track to slide to the wire feeding structure position to clamp the wire. The tinning mechanism 4 includes a first clamping assembly, a rotating assembly and a tinning material pool, the tinning material pool includes a flux pool and a tin liquid pool, the first clamping assembly is arranged on the rotating assembly, and the flux pool and the tin liquid pool are located below the rotating assembly.

[0038] The wire feeding mechanism 1, the wire cutting and stripping mechanism 3, the tinning mechanism 4 and the wire taking mechanism 5 are mechanical structures commonly used in the prior art, and their specific structures can refer to the corresponding specific structures in publication numbers CN103996958B and CN220107165U.

[0039] The wire feeding mechanism 1 is used to transport the wire, and the moving mechanism 2 drives the wire feeding mechanism 1 to move along the length and width directions of the frame to transport the wire to the wire cutting and stripping station and the first terminal bonding station; the first terminal bonding mechanism 6 is used to perform terminal bonding on the wire on the first terminal bonding station; the wire taking mechanism 5 is used to pull the wire on the wire cutting and stripping station so that the wire passes through the first clamping assembly, and at the same time, the wire to be cut position is opposite to the wire cutting and stripping station; the wire cutting and stripping mechanism 3 is used to cut and strip the wire at the wire to be cut position; the first clamping assembly is used to clamp the passed wire; the rotating assembly is used to drive the first clamping assembly to rotate so that the clamped wire end is transferred to the tinning material pool for tinning; the wire moving mechanism 8 moves between the first clamping assembly and the second terminal bonding mechanism 7, and is used to transport the wire clamped by the first clamping assembly to the second terminal bonding station; the second terminal bonding mechanism 7 is used to perform terminal bonding on the wire on the second terminal bonding station.

[0040] This double-end terminal soldering machine can automatically complete terminal bonding at one end of the wire and tinning at the other end according to the program settings, as well as terminal bonding at both ends of the wire, thereby meeting the processing needs of users.

[0041] The process of one-end terminaling and one-end tinning is as follows: the moving mechanism 2 drives the wire feeding mechanism 1 to send the input wire to the wire cutting and stripping mechanism 3 for first-end wire cutting and stripping, and then the wire after the first-end wire cutting and stripping is sent to the first terminal-attaching mechanism 6 for first-end terminal-attaching, and then the wire that has completed the first-end terminal is sent to the wire cutting and stripping mechanism 3 again. At this time, the wire cutting and stripping mechanism 3 and the first clamping assembly are opened, and the mechanical clamping hand of the wire taking mechanism 5 passes through the wire cutting and stripping mechanism 3 and the first clamping assembly to pull the wire that has completed the first-end terminal to the rear of the first clamping assembly, and then the first clamping assembly is used to clamp the wire. The holding assembly clamps the wire that has completed the terminal at the first end, and at the same time, the mechanical clamp of the wire-taking mechanism 5 releases the wire, and the wire tangent and stripping mechanism 3 performs wire tangent and stripping on the wire again, so that the wire is cut into two sections, realizing the first end tangent and stripping of the front section of the wire and the second end tangent and stripping of the rear section of the wire. The front section of the wire that has completed the tangent and stripping of the first end is conveyed to the first terminal-tying mechanism 6 again, and the rear section of the wire that has completed the tangent and stripping of the second end is driven by the rotating assembly to rotate the first clamping assembly so that the second end of the clamped wire is transferred to the tinning material pool for tinning, thereby completing the terminalizing at one end and the tinning at the other end.

[0042] The process of terminalizing at both ends is as follows: the moving mechanism 2 drives the wire feeding mechanism 1 to send the input wire to the wire cutting and stripping mechanism 3 for first-end wire cutting and stripping, and then the wire after the first-end wire cutting and stripping is sent to the first terminalizing mechanism 6 for first-end terminalizing, and then the wire that has completed the first-end terminalizing is sent to the wire cutting and stripping mechanism 3 again. At this time, the wire cutting and stripping mechanism 3 and the first clamping assembly are opened, and the mechanical clamp of the wire taking mechanism 5 passes through the wire cutting and stripping mechanism 3 and the first clamping assembly to pull the wire that has completed the first-end terminalizing to the rear of the first clamping assembly. Then, the first clamping assembly clamps the wire that has completed the first end terminal, and at the same time, the mechanical clamp of the wire taking mechanism 5 releases the wire, and the wire tangent and stripping mechanism 3 tangents and strips the wire again, so that the wire is cut into two sections, realizing the first end tangent and stripping of the front section of the wire and the second end tangent and stripping of the rear section of the wire. The front section of the wire that has completed the first end tangent and stripping is conveyed to the first terminal mechanism 6 again, and the rear section of the wire that has completed the second end tangent and stripping is conveyed by the wire moving mechanism 8 to the second terminal mechanism 7 for second end terminalling, thereby completing the double-end terminalling.

If the first sliding rail 81 is set in the X-axis direction, the second sliding rail 84 is set in the Y-axis direction, which is used to realize the forward, backward, left and right movement of the line moving mechanism 8.

[0044] The first mounting frame 83 is slidably mounted on the first sliding rail 81, the second sliding rail 84 and the second linear drive assembly 85 are mounted on the first mounting frame 83, the second mounting frame 86 is slidably mounted on the second sliding rail 84, and the rotary drive assembly 87 is mounted on the second mounting frame 86. The first linear drive assembly 82 drives the first mounting frame 83 to move on the first sliding rail 81, and the second linear drive assembly 85 drives the second mounting frame 86 to move on the second sliding rail 84, thereby driving the rotary drive assembly 87 and the second clamping assembly 88 thereon to move forward, backward, left, and right.

[0045] like Figure 5 As shown, the first linear drive assembly 82 includes a first motor 821, a first screw rod 822 connected to the rotating shaft of the first motor 821, and a first nut 833 threadedly assembled on the first screw rod 822.

The first mounting frame 83 is transmission-connected to the first screw rod 822 through the first nut 833. Under the control of the first motor, the first mounting frame 83 realizes movement on the first sliding rail 81 through the transmission structure composed of the first nut 833 and the first screw rod 822.

[0046] like Figure 6 As shown, the second linear drive assembly 85 includes a second motor 851, a second screw rod 852 connected to the rotating shaft of the second motor 851, a second nut threadedly assembled on the second screw rod 852, and the second sliding rail 84 is arranged in parallel with the second screw rod 852. A connecting plate 853 is provided on the second nut, and the second mounting frame 86 is connected to the connecting plate 853 and is transmission-connected to the second screw rod 852 through the second nut.

[0047] The rotary drive assembly 87 includes a rotary motor 871, a driving wheel 872 connected to the output shaft of the rotary motor 871, and a driven wheel 873 assembled and driven by a transmission belt 874 with the driving wheel 872, and the driven wheel 873 drives the second clamping assembly 88 to rotate.

[0048] The rotating motor 871 is provided with a first support plate 875 and a second support plate 876 arranged in a front-to-back relative spacing. The first support plate 875 and the second support plate 876 are connected and fixed to the second mounting frame 86. The output shaft of the rotating motor 871 passes through the first support plate 875 and the second support plate 876. The transmission assembly consisting of the driving wheel 872, the driven wheel 873 and the transmission belt 874 is located between the first support plate 875 and the second support plate 876.

[0049] The second clamping assembly 88 includes a clamping assembly 882, a telescopic driving unit 881, and a connecting pipe 883 connected between the clamping assembly 882 and the telescopic driving unit 881. The connecting pipe 883 passes through the first support plate 875 and the second support plate 876, and is supported on the first support plate 875 and the second support plate 876 through bearings. The driven wheel 873 is sleeved on the connecting pipe 883. The rotating motor 871 drives the driven wheel 873 to rotate through the driving wheel 872 and the transmission belt 874, and the driven wheel 873 drives the connecting pipe 883 to rotate, thereby driving the entire second clamping assembly 88 to rotate.

[0050] The chuck assembly 882 includes a chuck housing, two groups of transmission connecting rods rotatably mounted in the chuck housing, and two clamping plates 8820 placed outside the chuck housing. The telescopic rod 8810 of the telescopic drive unit 881 extends from the connecting pipe 883 into the chuck housing and is connected to the power input ends of the two transmission connecting rods. The power output ends of the two transmission connecting rods are respectively provided with connectors 8823, and the two clamping plates 8820 are respectively connected and fixed to the two connectors 8823. The transmission connecting rod includes a first transmission rod 8821 and a second transmission rod 8822.

The inner end of the first transmission rod 8821 is the power input end of the transmission connecting rod, and the outer end of the second transmission rod 8822 is the power output end of the transmission connecting rod. When the telescopic drive unit 881 is extended, the angle at the connection between the first transmission rod 8821 and the second transmission rod 8822 decreases, so that the inner ends of the two second transmission rods 8822 move away from each other and the outer ends move closer to each other, thereby achieving the closing of the two clamps 8820 to clamp the wire; when the telescopic drive unit 881 is retracted, the angle at the connection between the first transmission rod 8821 and the second transmission rod 8822 increases, so that the inner ends of the two second transmission rods 8822 move closer to each other and the outer ends move away from each other, thereby achieving the opening of the two clamps 8820.

[0051] The second clamping assembly 88 of the wire moving mechanism 8 opens and is conveyed to the rear end of the first clamping assembly. Facing the wire clamped by the first clamping assembly, the telescopic driving unit 881 drives the two clamping plates 8820 to close to clamp the wire. At the same time, the first clamping assembly releases the clamped wire, and the wire is transferred to the second clamping assembly 88 and conveyed to the second terminal terminal station. During the conveying process, the rotating driving assembly 87 drives the second clamping assembly 88 to rotate 180°.

[0052] A discharge conveyor belt 9 is provided between the first clamping assembly and the second terminal-bonding mechanism 7. The discharge conveyor belt 9 is located below the second clamping assembly 88. After the tinning process or the second terminal-bonding process is completed, the second clamping assembly 88 clamps and conveys the wire to the top of the discharge conveyor belt 9. The rotary drive assembly 87 drives the second clamping assembly 88 to rotate 90 degrees (such as Figure 7 As shown), the opening direction of the two clamping plates 8820 is toward the direction of gravity, and the processed wire material falls smoothly onto the discharge conveyor belt 9.

[0053] The wire moving mechanism 8 has the functions of moving in the X-axis direction, moving in the Y-axis direction and rotating by 180 degrees, so as to better cooperate with the wire conveying.
