[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] like Figures 1 to 14The lead wire welding production line shown is used to plug the lead wire into the electrode head and weld it, including a frame 1, the frame 1 is provided with a main conveyor line 11, and a wire cutting mechanism 2, a wire stripping mechanism 3, a wire twisting mechanism 4, a wire inserting mechanism 5, a welding mechanism 6 and a unloading mechanism 7 arranged in sequence from back to front along the main conveyor line 11, the rear end of the main conveyor line 11 is also provided with a lead wire loading station (the lead wire is manually mounted on the second clamp 82), the main conveyor line 11 is provided with a first clamp 81 for clamping the electrode head and a second clamp 82 for clamping the lead wire, and the main conveyor line 11 can convey the first clamp 81 and the second clamp 82 from back to front, the left and right sides of the main conveyor line 11 are respectively provided with a first return line 12 for reflowing the first clamp 81 and a second return line 13 for reflowing the second clamp 82, the first return line 12 is provided with an electrode head loading mechanism 9 for mounting the electrode head on the first clamp 81. Among them, the wire cutting mechanism 2 (wire cutting machine) and the wire stripping mechanism 3 (wire stripping machine) are relatively common and will not be described in detail here.

[0035] The present invention can realize wire cutting, wire stripping, wire twisting, electrode head loading, wire insertion, welding and unloading and reflow of two clamps. The whole process is automated with a higher degree of automation, which simplifies the processing process and greatly improves the processing efficiency of the product, so that it can meet the needs of large-scale product processing.

[0036] In addition, the present invention uses two fixtures to clamp the lead wire and the electrode head respectively, which facilitates the transmission, positioning and processing of the lead wire and the electrode head. The present invention also uses the first return line 12 and the second return line 13 to reflux the first fixture 81 and the second fixture 82 respectively, recycling the first fixture 81 and the second fixture 82.

[0037] More specifically, Figure 1-Figure 4 As shown, the main conveying line 11 includes a first conveying track 111 and a second conveying track 112 arranged along the front-to-back direction, and the first clamp 81 slides on the first conveying track 111, and the second clamp 82 slides on the second conveying track 112. The main conveying line 11 also includes a main conveying drive device 113 that can push the first clamp 81 and the second clamp 82 to move forward.

[0038] The main conveying drive device 113 includes a main conveying driver 1131 (the main conveying driver 1131 is preferably a cylinder) provided on the frame 1, and a transmission rod 1132 slidably connected to the frame 1 along the front-back direction (the sliding connection here means sliding connection through a sliding pair), and the transmission rod 1132 is connected to the output end of the main conveying driver 1131. The transmission rod 1132 is provided with a mechanism that can push the first clamp 81 or the second clamp 82 forward in one direction (only one of the first clamp 81 and the second clamp 82 needs to be pushed, Figure 4The figure shows a push block assembly 1133 that pushes the second clamp 82. The present invention utilizes a main conveyor driver 1131 to drive the transmission rod 1132 to slide back and forth, and a push block assembly 1133 on the transmission rod 1132 to unidirectionally push the first clamp 81 or the second clamp 82 forward. This ensures that each first clamp 81 and second clamp 82 remains in a predetermined position during each movement, eliminating the need for a separate positioning structure and simplifying the structure.

[0039] More specifically, the push block assembly 1133 includes a base fixed to the transmission rod 1132. The base is provided with a push block, the rear end of which is rotatably connected to the base. A spring is provided between the front end of the push block and the base, thereby pressing the front end of the push block upward. Therefore, when the transmission rod 1132 slides forward, the front end of the push block tilts upward and protrudes from the base, where it contacts the first clamp 81 or the second clamp 82, pushing the first clamp 81 or the second clamp 82 forward. When the transmission rod 1132 slides backward, the front end of the push block compresses the spring and retracts into the base, allowing the first clamp 81 or the second clamp 82 to remain in its original position. Therefore, the push block assembly 1133 can push the first clamp 81 or the second clamp 82 forward in one direction. Of course, a certain amount of friction should exist between the first clamp 81 and the first conveyor rail 111, or between the second clamp 82 and the second conveyor rail 112.

[0040] More specifically, Figure 6 、 Figure 7 As shown, the wire twisting mechanism 4 includes a fixed platform 41, a wire clamping and positioning component 42 provided on the fixed platform 41, a mobile platform 43 slidably connected to the fixed platform 41, and a displacement driver 44 for driving the mobile platform 43 to slide left and right. The mobile platform 43 is provided with a rotation driver 45, and the output end of the rotation driver 45 is provided with a plurality of rotatable wire twisting components 46. Each of the wire twisting components 46 includes a clamping claw cylinder 461 and a wire twisting claw 462 provided at the output end of the clamping claw cylinder 461. After the lead wire is stripped, the wire core inside needs to be twisted together for subsequent insertion. The present invention uses the wire twisting claw 462 to clamp the lead wire core (but not to clamp it to death), and then rotates and retreats at the same time to complete the wire twisting process. Both the displacement driver 44 and the rotation driver 45 are preferably servo motors or stepper motors. A ball screw or similar screw pair is provided between the displacement driver 44 and the movable platform 43 for transmission. A synchronous belt and synchronous pulley pair is used to transmit power between the rotation driver 45 and one of the wire twisting assemblies 46, as well as between two adjacent wire twisting assemblies 46. Furthermore, the displacement driver 44 and the rotation driver 45 should coordinate their movements to achieve simultaneous retraction and tightening of the wire, thereby achieving a long and tight wire.

[0041] More specifically, Figure 8 、 9As shown, the wire insertion mechanism 5 includes a wire clamping assembly 51 for clamping the lead wire and capable of moving up, down, left and right, a flipping assembly 52 for clamping the electrode head and capable of flipping the electrode head, and a translation assembly 53 for driving the flipping assembly 52 to move left and right so that the lead wire is inserted into the electrode head in a vertical state, and the axis of the flipping of the flipping assembly 52 is along the front-to-back direction.

[0042] The clamping assembly 51 is primarily used to clamp and secure each lead wire and position it for subsequent insertion. Furthermore, the clamping assembly 51 includes a two-axis translation module capable of vertical, horizontal, and horizontal movement. The output end of the two-axis translation module is equipped with several pairs of clamping jaws and an opening and closing actuator (preferably a cylinder) for driving the opening and closing of each clamping jaw.

[0043] More specifically, Figure 9 As shown, the translation assembly 53 includes a translation driver 531 and a translation frame 532 arranged at the output end of the translation driver 531, the flip assembly 52 includes a flip frame 521 rotatably connected to the translation frame 532, the flip frame 521 is connected to the flip driver 522, and the flip frame 521 is provided with a clamp fixing device 523 for clamping the first clamp 81, a wire pressing assembly 524 for a wire pressing head, and a hot pressing assembly 525 for hot melting.

[0044] Furthermore, the translation driver 531 is preferably a servo motor or a stepper motor, and its output end is connected to the translation frame 532 through a screw pair. The flip driver 522 is preferably a cylinder, and its output end is connected to the flip frame 521 through a connecting rod. The clamp fixing device 523 includes a slot that can cooperate with the first clamp 81, and a fixed cylinder, the output end of which extends to press the first clamp 81 to fix it. The wire pressing assembly 524 includes a wire pressing cylinder, and the output end of the wire pressing cylinder is provided with a plurality of push rods, and a buffer spring is further provided between each push rod and the output end of the wire pressing cylinder. After the push rod is extended, the lead wire end inserted into the electrode head can be bent and pressed into the socket on the electrode head to avoid protruding wire ends. The hot pressing assembly 525 includes a hot pressing cylinder, and an electrically powered hot pressing block is provided at the output end of the hot pressing cylinder. The function of the hot pressing assembly 525 is to hot press the lead wire inserted into the electrode head, melt the lead wire into the electrode head, and fix it on the electrode head.

[0045] In the present invention, the electrode head is clamped in the first clamp 81, and the first clamp 81 is clamped on the flip frame 521. During the wire insertion process, the first step is that the wire clamping assembly 51 first positions the lead wire; the second step is that the flip driver 522 is started to flip the flip frame 521 90 degrees, adjust the electrode head to a vertical state, and expose the socket on the electrode head; the third step is that the translation driver 531 is started to drive the translation frame 532 and the entire flip assembly 52 to move to the right, that is, gradually approach the wire clamping assembly 51, and the lead wire head is slowly inserted into the socket on the electrode head; the fourth step is that the flip driver 522 is started, the flip frame 521 is flipped back 90 degrees, and the first clamp 81 and the electrode head become horizontal. This process completes the folding line; the fifth step is that the wire pressing assembly 524 is started to press and bend the lead wire head inserted into the electrode head and press it tightly into the socket on the electrode head; the sixth step is that the hot pressing assembly 525 is started to melt the lead wire into the electrode head and fix it. In the present invention, the wire clamping assembly 51 positions the lead wire, and the translation assembly 53 and the flip assembly 52 cooperate with each other to insert the wire, with high insertion accuracy; the lead wire is bent 90 degrees and is easy to detach, and the wire pressing assembly 524 and the hot pressing assembly 525 fix the lead wire, so that the lead wire and the electrode head are firmly connected.

[0046] More specifically, Figure 10 As shown, the welding mechanism 6 includes a welding head 61 and a displacement device 62 for driving the welding head 61 to move up and down and left and right. The welding mechanism 6 is mainly used to weld the lead wire end and the contact on the electrode head together. Figure 11 As shown, a hot pressing mechanism 63 for pressing down the solder joint is provided in front of the soldering mechanism 6. The hot pressing mechanism 63 includes a hot pressing driver 631. The output end of the hot pressing driver 631 is provided with a heating component 632 that can be raised and lowered. The hot pressing mechanism 63 is mainly used to press down the solder joint.

[0047] More specifically, Figure 5 As shown, the first clamp 81 is provided with a clamp cover 811 for opening and closing the first clamp 81, and a first buckle 812 for locking the clamp cover 811. One side of the clamp cover 811 is hinged to the first clamp 81, and a torsion spring is provided between the two. When one end of the first buckle 812 is pushed downward, the clamp cover 811 is unlocked. The second clamp 82 is provided with a second buckle 821 for opening and closing the second clamp 82, and when one end of the second buckle 821 is pushed downward, the second clamp 82 is opened. The present invention uses two clamps to fix the electrode head and the lead wire respectively, so as to facilitate subsequent transmission, positioning, wiring, and grasping.

[0048] More specifically, Figure 2 、 Figure 3 、 Figure 12The unloading mechanism 7 includes a cover opening device 71 on one side of the main conveyor line 11 and used to open the first clamp 81, an ejection device 72 provided below the front end of the main conveyor line 11 and used to eject the electrode head in the first clamp 81 upwards, and a two-axis translation module 73 (a common module, not repeated here) provided above the ejection device 72, and the output end of the two-axis translation module 73 can move up and down and forward and backward, and the output end of the two-axis translation module 73 is provided with a material picking clamping component 74, a pressing device 75 for opening the second clamp 82, and a vacuum adsorption component 76 for grabbing the electrode head.

[0049] Furthermore, the cover opening device 71 includes an opening cylinder and a cover-opening pressing rod at its output end. The pressing rod extends downward and presses one end of the first latch 812, thereby opening the first latch 812. The clamp cover 811 is automatically opened by the torsion spring. The ejection device 72 includes an ejection cylinder and several ejection rods at the output end of the ejection cylinder. The first clamp 81 is provided with several through-holes. When the ejection rods extend upward, they pass through the corresponding through-holes and eject the electrode tip from the first clamp 81.

[0050] The material picking clamping assembly 74 includes a plurality of first material picking jaws 741 for clamping the lead wire at the first clamp 81, a first material picking driver 742 (preferably a cylinder) for driving each first material picking jaw 741 to open and close, a second material picking jaw 743 for clamping the lead wire at the second clamp 82, and a second material picking driver 744 (preferably a cylinder) for driving the second material picking jaw 743 to open and close.

[0051] like Figure 12 As shown, the vacuum adsorption assembly 76 includes a base 761 that is slidably connected in the up and down directions (connected by a sliding pair) to the output end of the two-axis translation module 73, and a vacuum suction cup 762 is provided on the base 761. A buffer spring 763 is also provided between the base 761 and the output end of the two-axis translation module 73. The main functions of the vacuum adsorption assembly 76 are as follows: Unlike the first material picking jaw 741 and the second material picking jaw 743, which both grab the lead wire, the vacuum adsorption assembly 76 directly grabs the electrode head. In this way, even if there are defective products (the lead wire and the electrode head are not welded well, and if only the lead wire is grabbed, the electrode head may not be able to rise), the vacuum adsorption assembly 76 can also directly remove the electrode head to prevent the defective electrode head from remaining in the first fixture 81 and affecting the subsequent use of the first fixture 81.

The output end of the first rodless cylinder is provided with a first docking station capable of docking with the first conveyor track 111. The first docking station is provided with a first chute capable of cooperating with the first fixture 81. The first docking station is also provided with a first push block and a first push cylinder for driving the first push block. The first docking station is first aligned with the first conveyor track 111. After the first fixture 81 enters the first chute from the first conveyor track 111, the first rodless cylinder drives the first docking station to move above the first return conveyor 121. The first push cylinder is activated, and the first push block pushes the first fixture 81 onto the first return conveyor 121.

[0054] Similarly, the second transfer device 132 includes a second rodless cylinder located between the second return conveyor 131 and the main conveyor line 11. The output end of the second rodless cylinder is equipped with a second docking station capable of docking with the second conveyor track 112. The second docking station is equipped with a second chute capable of cooperating with the second fixture 82. The second docking station is also equipped with a second push block and a second push cylinder that drives the second push block. The second docking station is first aligned with the second conveyor track 112.

The second push cylinder is activated, and the second push block pushes the second fixture 82 onto the second return conveyor 131.

[0056] Furthermore, the electrode head grasping assembly 91 is preferably a vacuum suction cup structure. The feeding drive device 93 is preferably a cylinder, and a gear rack structure is provided between the feeding drive device 93 and the transmission shaft 92.

The electrode head grasping assembly 91 is fixed on the transmission guide rail 942, so that the electrode head grasping assembly 91 can slide freely in the up-down and left-right directions. The transmission guide rail 942 is also provided with a guide shaft 943 that is arranged in the front-back direction.

In this way, when the transmission shaft 92 rotates, the guide shaft 943 will move along the inverted U-shaped guide groove 9511, so that the electrode head grasping assembly 91 moves along the inverted U-shaped path, so that a series of loading steps of descending-grabbing the electrode head-ascending-leftward movement-descending-releasing the electrode head-ascending-rightward movement and resetting can be realized. The present invention only uses a cylinder driver, and then uses a purely mechanical transmission structure 94 and guide structure 95 to complete the loading steps.
