[0035] In addition, a brief explanation is given for the orientations involved in this specific implementation: the directions or positional relationships indicated by "front", "rear", "up", "down", "left", "right", etc., of each structural member mentioned below refer to the orientations or positional relationships shown in the accompanying drawings; these positional relationships are only for the convenience of description and simplified description, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 - Fig.13As shown, an audio line tinning welding device according to a preferred embodiment of the present invention comprises a frame 1, a controller, a plurality of bendable jigs 2 and an audio line feeding device connected to the jig 2 and used to drive the jig 2 to move a preset distance along the length direction of the frame 1, the jig 2 is used to load the audio line, and also comprises a bracket 3 located above the audio line feeding device, a telescopic mechanism 4 is arranged on the bracket 3, a tin furnace mechanism 5 is arranged on the frame 1 at a position corresponding to the telescopic mechanism 4, the telescopic mechanism 4 bends the jig 2 to allow the audio line to extend into the tin furnace mechanism 5 for tinning, the controller, the bracket 3, the audio line feeding device and the tin furnace mechanism 5 are all arranged on the frame 1, and the telescopic mechanism 4, the audio line feeding device and the tin furnace mechanism 5 are all electrically connected to the output end of the controller.

[0039] The mechanism of the present invention can simulate the manual tinning method, rotate the tinning at a 90-degree angle, and have uniform quality. When welding products, the products are pre-tinned, and the tin points are saturated after welding, with less cold solder joints and false solder joints.

[0040] The jig 2 includes a jig seat, a fixed block 22 rotatably connected to the jig seat, and a reset tension spring 23 arranged between the jig seat and the fixed block 22. The jig seat is fixedly connected to the audio cable feeding device, and pressure blocks A24 are rotatably arranged on both sides of the fixed block 22. A compression spring 25 is arranged between the two pressure blocks A24. The pressure block A24 is used to fix the audio cable on the fixed block 22.

[0041] A jig mechanism that simulates the process of holding the core wire manually and bending the fingers or wrists at a certain angle to dip the wire into tin. A cylindrical pin is installed on each of the fixed block and the jig seat, and the two cylindrical pins are connected by a reset spring. A cylindrical pin is installed at the connection between the jig seat and the fixed block to form a freely movable joint between the two parts. When the telescopic mechanism is extended and pressed down, the fixed block is rotated a certain angle relative to the jig seat. When the telescopic mechanism is returned to its original position, the fixed block will automatically return to its original state before rotation due to the action of the reset spring. The two pressure blocks are also strung to the fixed block by two cylindrical pins. Below the cylindrical pin, a compression spring is used to make the two pressure blocks bear force against each other, and the tops of the pressure blocks are closed to fix the audio cable.

[0042] The telescopic mechanism 4 includes a telescopic cylinder 41, which is electrically connected to the output end of the controller, and is fixedly connected to the bracket 3. The driving end of the telescopic cylinder 41 is connected to a push rod 42, and the lower end of the push rod 42 is rotatably connected to a bearing 43, and the bearing 43 is used to contact the fixed block 22 to bend the fixed block 22.

[0043] When the fixture comes under the telescopic mechanism, the telescopic cylinder in the telescopic mechanism will push the push rod, and the bearing connected to the push rod will come into contact with the fixed block in the fixture. The fixed block will rotate 90 degrees under the action of the push rod, and the end face of the audio cable will be immersed in the tin furnace for about one millimeter to complete the simulation of artificial tinning. When the telescopic mechanism returns to its position, the fixed block will automatically return to its original state before rotation due to the action of the tension spring.

[0044] The tin furnace mechanism 5 includes a lifting cylinder 51, which is electrically connected to the output end of the controller. The driving end of the lifting cylinder 51 is connected to a support plate 52, and a tin furnace 53 is arranged on the support plate 52. The tin furnace 53 contains molten tin.

[0045] The tin furnace mechanism 5 also includes a transverse cylinder 54 arranged on the support plate 52, and a frame 55 is provided at the driving end of the transverse cylinder 54. A cleaning plate 56 is rotatably connected inside the frame 55. One end of the cleaning plate 56 extends into the tin furnace 53, and the other end of the cleaning plate 56 is connected to a pushing cylinder 57. The pushing cylinder 57 is used to drive the cleaning plate 56 to rotate so that the cleaning plate 56 is immersed in the tin water. The transverse cylinder 54 and the pushing cylinder 57 are both electrically connected to the output end of the controller.

[0046] When the tinning mechanism starts to work, the lifting cylinder at the bottom is pushed out, and the mechanism as a whole moves upward to the specified position. The two transverse cylinders and the pushing cylinder at the rear work at the same time. While the cleaning plate moves backward under the action of the transverse cylinder, the cleaning plate is thrust by the pushing cylinder to make a lever movement and tilt downward, and the tin oxide on the surface of the tin furnace is cleaned.

[0047] A first positioning mechanism 6 is provided on the bracket 3 in front of the telescopic mechanism 4, and a twisting and cutting mechanism 7 is provided on the frame 1 at a position corresponding to the first positioning mechanism 6. After the first positioning mechanism 6 positions the jig 2, the twisting and cutting mechanism 7 is used to twist and cut the audio cable.

[0048] The shearing mechanism 7 includes a fixed plate 71 and a first transverse cylinder 72 and a second transverse cylinder 73 arranged in parallel on the fixed plate 71. The driving end of the first transverse cylinder 72 is connected to a thread twisting robot 74, and the thread twisting robot 74 is used to twist the audio line. Specifically, in this embodiment, the thread twisting robot is fixedly connected to the first transverse cylinder through a thread twisting robot slider. The first transverse cylinder 72, the second transverse cylinder 73 and the thread twisting robot 74 are all electrically connected to the output end of the controller. The driving end of the second transverse cylinder 73 is connected to a swing arm slider 75, and the upper end of the swing arm slider 75 is fixedly connected to a swing arm connecting block 76, the end of the swing arm connecting block 76 is rotatably connected to the upper swing arm 77 and the lower swing arm 78, the end of the upper swing arm 77 is rotatably connected to the upper slider 79, the end of the lower swing arm 78 is rotatably connected to the lower slider 710, the upper slider 79 and the lower slider 710 are both slidably sleeved on the guide shaft 711, the guide shaft 711 is fixedly set on the base 712, the base 712 and the lower end of the fixed plate 71 are fixedly connected, the lower end of the upper slider 79 is provided with an upper tool 713, the upper end of the lower slider 710 is provided with a lower tool 714, the upper tool 713 and the lower tool 714 are used to cut the audio cable.

[0049] Based on the above technical solution, the wire twisting robot is mainly composed of a flat-open cylinder and upper and lower wire twisting blocks. The two clamps of the parallel cylinder are respectively connected to the upper and lower wire twisting blocks. The slider of the wire twisting robot is fixed on the first transverse optical axis through a guide sleeve. The first transverse optical axis and the fixed plate are fixedly connected. The slider of the wire twisting robot is connected to the first transverse cylinder with a floating joint. The wire twisting robot is fixed on the slider of the wire twisting robot. Because the guide sleeve can only reciprocate laterally, the wire twisting robot can only move laterally. The power source for the transverse movement of the wire twisting robot is the first transverse cylinder. When the upper and lower wire twisting blocks bite the audio line, the first transverse cylinder drives the wire twisting robot to move backward. The audio wire harness will be automatically leveled by the clamping force. This function is completed.

[0050] Based on the above technical solution, there are two guide shafts, and the two guide shafts are fixed on the base. The upper swing arm and the lower swing arm are both mechanical swing arms, so the upper and lower sliders can only reciprocate vertically along the guide shafts. The upper slider is connected to the upper tool, and the lower slider is connected to the lower tool; both sides of the upper and lower sliders are connected with mechanical swing arms, and the end of the mechanical swing arm is fixed on the swing arm connecting block, and the swing arm connecting block is fixed on the swing arm slider. The swing arm slider is fitted with the second transverse optical axis, and the second transverse optical axis is fixed on the fixed plate. The swing arm slider is connected to the second transverse cylinder with a floating joint. Therefore, the swing arm slider can only move laterally. The power source for the transverse movement of the swing arm slider is the second transverse cylinder.

[0051] The upper cutter is an oblique cutter with teeth on the blade; the lower cutter is a flat cutter with teeth on the blade. The upper and lower cutters can be installed interchangeably. Different from ordinary cutters, this new type of cutter can handle relatively soft wire harnesses, anti-breaking wires, cotton wires, enameled copper wire harnesses, data cables, power cables, various charging and audio cables, including all objects that can be cut by the cutter.

[0052] The shearing mechanism 7 also includes a slider module 715 and an adjusting rod 716, the adjusting rod is a plum blossom-shaped screw rod, the base 712 is slidably set on the slider module 715, the slider module is fixedly connected to the frame through a support column, the adjusting rod 716 passes through the slider module 715 and the fixed plate 71 in sequence, the adjusting rod 716 and the slider module 715 are threadedly connected, and the adjusting rod 716 and the fixed plate 71 are fixedly connected.

[0053] The function of the slider module is to move the mechanism forward and backward as a whole under necessary conditions, such as when the cutting length of the audio cable needs to be changed, by twisting the plum blossom screw rod.

[0054] Specific working principle of rubbing and shearing mechanism:

[0055] The audio cable stops after arriving at the twisting and shearing mechanism station. After the first positioning mechanism is positioned, the twisting and shearing mechanism starts to work. When the mechanism does not move, the upper and lower cutters are in an open state, and the upper and lower twisting blocks are also in an open state. After starting to work, the first transverse cylinder extends, the twisting robot moves forward to the specified position, the twisting robot closes, the audio cable is clamped, the first transverse cylinder shrinks to the specified position, and the twisting robot will also move backward to the specified position after clamping the line under the action of the first transverse cylinder. Immediately afterwards, the second transverse cylinder shrinks to the specified position, the swing arm slider moves backward, and the mechanical swing arm is closed by tension. The mechanical swing arm is connected to the upper and lower sliders, so the upper and lower sliders under tension will also undergo vertical closing movement. Because the upper and lower cutters are fixed on the upper and lower sliders respectively, the audio cable will be cut after the cutters are engaged. When the audio cable is cut, the second transverse cylinder quickly extends to its original position, and the upper and lower cutters are quickly opened by thrust. Finally, the twisting robot opens and the twisting and shearing is completed.

[0056] A second positioning mechanism 8 is provided on the bracket 3 at the rear side of the telescopic mechanism 4, and a soldering mechanism 9 is provided on the frame 1 at a position corresponding to the second positioning mechanism 8, and the second positioning mechanism 8 is used to fix the audio cable on the fixture 2, and the soldering mechanism 9 includes a first linear module 91, and the driving end of the first linear module 91 is connected to the second linear module 92, and the driving end of the second linear module 92 is connected to the vertical cylinder 93, and the driving end of the vertical cylinder 93 is connected to a soldering pen 94, and the soldering pen 94 is used to solder the audio cable and the pin, wherein the first linear module 91, the second linear module 92 and the vertical cylinder 93 are all electrically connected to the output end of the controller.

[0057] The main working principle of the soldering mechanism: the soldering pen is pushed by the vertical cylinder for spot welding. Because the audio line and the pin have four soldering points, a linear module is needed to control the reciprocating motion of the soldering pen for step-by-step spot welding.

[0058] The first positioning mechanism 6 and the second positioning mechanism 8 both include a positioning cylinder 100, which is electrically connected to the output end of the controller. The driving end of the positioning cylinder 100 is connected to a connecting block 101. The lower end of the connecting block 101 is provided with two correction blocks 102. The two correction blocks 102 are used to engage on both sides of the fixed block 22. The lower end of the connecting block 101 is located between the two correction blocks 102 and is also provided with a pressing block B103. The pressing block B103 is used to fix the audio cable on the fixed block 22.

[0059] When the jig is working, the secondary positioning is performed to ensure that the position of the jig is not deviated. When the positioning cylinder is pushed out, the correction block will be stuck in the position of the jig. At this time, the pressure block will fix the audio cable. When the audio cable is pulled externally, the part of the audio cable fixed by the pressure block will not loosen. Ensure that there is no deformation, displacement, miscutting or miswelding during product processing.

[0060] An audio line tinning welding device also includes a vibration plate 10 arranged on the frame 1, and the vibration plate 10 is connected to a material channel 11, and the material channel 11 is used to transport pins. A rotating cylinder is also arranged on the frame 1 at the outlet of the material channel 11, and the driving end of the rotating cylinder is connected to a material picking robot 12. The material picking robot 12, the rotating cylinder and the output end of the controller are electrically connected, and the material picking robot 12 is used to clamp the pins from the outlet of the material channel 11.

[0061] The vibrating plate sends the pin to the material channel. After the material picking robot picks up the material, the rotary cylinder rotates 90 degrees clockwise. After the position is accurate, the first feeding robot will clamp the pin, and the rotary cylinder returns to its original position. This action is repeated.

[0062] An audio line tinning welding device also includes a feeder, the feeding mechanism includes a first feeding cylinder 13 and a pin plate 14 arranged on a frame 1, the movement direction of the first feeding cylinder is horizontal, and a limit mechanism 15 and a pin placement block 16 are arranged in parallel on the pin plate 14, the driving end of the first feeding cylinder 13 is connected to a second feeding cylinder 17, the movement direction of the second feeding cylinder is longitudinal, the moving direction of the first feeding cylinder 13 is perpendicular to the moving direction of the second feeding cylinder 17, the driving end of the second feeding cylinder 17 is arranged in parallel with a first feeding manipulator 18, a second feeding manipulator 19 and a third feeding manipulator 20, a side of the third feeding manipulator 20 is provided with an ejection cylinder, and the driving end of the ejection cylinder is connected to The ejector manipulator 21, the first feeding manipulator 18 is used to clamp the pin from the material picking manipulator 12 and insert the pin into the limiting mechanism 15, the second feeding manipulator 19 is used to clamp the pin from the limiting mechanism 15 and insert the pin into the pin placement block 16, the third feeding manipulator 20 is used to clamp the pin from the pin placement block 16 and pass it to the ejector manipulator 21, the ejector manipulator 21 ejects the pin to the bottom of the soldering pen 94, wherein the first feeding cylinder 13, the second feeding cylinder 17, the ejection cylinder, the first feeding manipulator 18, the second feeding manipulator 19, the third feeding manipulator 20 and the ejector manipulator are all electrically connected to the output end of the controller.

[0063] The limiting mechanism 15 includes a pin correction block 151 and a fixer 152 which are arranged relatively up and down on the pin plate 14. The pin correction block 151 is slidably connected to the pin plate 14. Specifically, the pin correction block is slidably connected to the pin plate through a slide rail. The fixer 152 is connected to a rotating motor, and the rotating motor is electrically connected to the output end of the controller. A limiting notch 153 is provided at the lower end of the pin correction block 151, and the limiting notch 153 is used to clamp on the outside of the pin to correct its position.

[0064] There are three manipulators on the second feeding cylinder, and the three manipulators are driven by the first feeding cylinder and the second feeding cylinder to realize lateral and longitudinal movement within the plane. When the first feeding manipulator receives the pin sent by the picking manipulator, it clamps it and moves horizontally. After the first feeding manipulator reaches the position of the fixture, it moves longitudinally under the action of the cylinder. When the manipulator reaches the longitudinal position, it will force the pin correction block to rise through the principle of the slope and the slider. After the pin is inserted into the fixture position, the manipulator retreats longitudinally. The pin correction block will come down under the action of the spring and gravity, and it will open a limiting notch, and then the rotating motor will drive the fixture to rotate (the fixture has positioning beads or other fixing methods. The final result is that when there is no external force, the pin will rotate with the fixture after being inserted into the fixture. When subjected to external force, the fixture rotates and the pin slips inside the fixture). When the limiting notch of the pin correction block is stuck to the pin, the rotating motor drives the fixture to rotate at least 1 circle or more circles. After the protruding plastic part of the pin is stuck by the pin correction block, it will slip inside the fixture. After multiple circles, the rotating body stops, and the position where the pin slips and does not rotate with the fixture is the position corrected by the mechanism, and finally the soldering surface of the pin is unified in one direction. At this time, the second feeding robot clamps the continuous pin and sends the pin to the pin placement block horizontally. The third feeding robot clamps the pin from the pin placement block. Under the action of the second feeding cylinder, the robot continues to move horizontally to the specified distance to pass the pin to the ejector robot, and then the ejector cylinder moves the ejector robot vertically to the solderable distance, and a workflow is completed.

[0065] The audio cable feeding device includes a servo motor and a synchronous belt transmission mechanism powered by the servo motor, the servo motor is electrically connected to the output end of the controller, and each of the jigs 2 is evenly fixed on the synchronous belt in the synchronous belt transmission mechanism.

[0066] The fixture is locked on the synchronous belt by screws. The synchronous belt has multiple working positions. The working power relies on the motor to connect the output shaft through the synchronous belt for power transmission to achieve normal operation of the mechanism.

[0067] The formation of a complete equipment is inseparable from the cooperation of each working mechanism. Each mechanism is independent of each other but closely connected.

[0068] The following is a summary of the basic working principles of audio cable tinning equipment:

[0069] A wire placement robot is also provided at the initial position of the jig. The wire placement robot is fixedly connected to the frame. The wire placement robot is in a closed state by default. The closing of the wire placement robot causes the pressure block of the jig to open, so that the audio cable can be fixed on the jig.

[0070] After the audio cable is arranged, the controller controls the audio cable feeding device to move forward one station, and at the same time, the line placing robot is opened. When the audio cable reaches the working position of the rubbing and shearing mechanism, the first positioning mechanism plays a role.

[0071] The first positioning mechanism positions the fixture through the action of the correction block and the pressure block. The rubbing and cutting mechanism starts to work, and the originally uneven audio cables are rubbed to the same level after being rubbed by the rubbing block. The audio cables are cut as a whole under the action of the cutter, which is convenient for subsequent tinning.

[0072] The audio cable feeding device reaches the tinning station. After the tinning mechanism reaches the predetermined position, the telescopic mechanism extends to rotate the fixture to a certain angle. The audio cable is tinned, the telescopic mechanism returns to its original position, and the fixed block of the fixture returns to its original state before rotation under the action of the reset spring.

[0073] Then the audio cable feeding device moves to the soldering mechanism working position. The material picking robot grabs the pin head and transfers the pin to the first feeding robot through the rotating cylinder. After the pin is sent to the holder, the pin correction block corrects the pin. The pin will slip after finding the correct position. After several turns, the rotating body stops and the product is in the right position. At this time, the second feeding robot grabs the pin, and after multiple layers of transfer, the pin is sent to the bottom of the soldering pen of the soldering mechanism.

[0074] While the soldering mechanism is working, the second positioning mechanism in front of the soldering station will reposition the fixture during the process to ensure the soldering accuracy. After the soldering is completed, the audio cable feeding device moves the audio cable and the audio cable naturally slides into the material tray under the action of the top plate. The audio cable and the pin complete the welding steps, and all the above actions are repeated for each subsequent station.

[0075] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
