Description

Technical Field

[0001] The utility model relates to the technical field of welding machines, in particular to a semi-automatic enameled wire pin welding machine. Background Art

[0002] In the current electronics industry, when welding electronic components with enameled wire pins, it is often necessary to manually remove the paint in advance, and then use a high-temperature electric soldering iron and soldering to weld the enameled wire. This welding method has a long operating process and low welding quality. There is an enameled wire spot welding machine that uses an enameled wire spot welding head made of a high-density tungsten-molybdenum alloy for welding. The welding head removes the paint through contact resistance, reducing the steps of enameled wire welding. However, the enameled wire is thin, and it is not easy to align it using manual welding. It is easy for the enameled wire spot welding head to spark before it contacts the enameled wire, resulting in a blank weld. Blank weld refers to sparking when the tip of the enameled wire spot welding head does not contact other objects that can conduct heat. The enameled wire spot welding head is a precision component. When a blank weld occurs, the life span will be greatly reduced. Utility Model Content

[0023] like Figure 1 As shown, it is a structural schematic diagram of a semi-automatic enameled wire pin welding machine provided by an embodiment of the utility model. In this embodiment, the semi-automatic enameled wire pin welding machine includes a three-axis driving platform 1, a welding assembly 2, a welding platform 3 and a positioning assembly 4.

[0024] Among them, in this embodiment, the three-axis drive platform 1 is installed on the frame 5, the welding assembly 2 is installed on the mobile end of the three-axis drive platform 1, the welding platform 3 is used to carry the components to be welded and dock with the welding assembly 2, and the positioning assembly 4 is used to position the components to be welded. The positioning assembly 4 is fixed on the welding platform 3 during welding. This embodiment realizes automatic welding through the three-axis drive platform 1, which can improve the stability during welding and reduce the occurrence of empty welding. The components to be welded can be manually installed on the positioning assembly 4. The positioning assembly 4 can be any component that can position the components to be welded and can be detachably fixed on the welding platform 2. The positioning assembly 4 can be selected and designed according to the components to be welded. An exhaust pipe is also installed on the three-axis drive platform 1. The other end of the exhaust pipe can be connected to a negative pressure mechanism to discharge waste during welding, thereby reducing the harm to workers caused by waste pollution generated by welding. Figure 1 The center exhaust pipe was too long and was cut off.

[0025] The three-axis drive platform 1 includes an X-axis moving plate 11, a Y-axis moving frame 12 and a Z-axis electric cylinder 13; the X-axis moving plate 11 is installed on the frame 5, and the Y-axis moving frame 12 is fixed on the X-axis moving plate 11; a vertical mounting plate 14 is installed on the moving end of the Y-axis moving frame 12, and the Z-axis electric cylinder 13 is installed on the vertical mounting plate 14; the enameled wire spot welding head 21 of the welding assembly 2 is installed on the moving end of the Z-axis electric cylinder 13, and the enameled wire spot welding head 21 is installed vertically downward.

[0026] Among them, the X-axis moving plate 11 is used to realize the movement of the Y-axis moving frame 12 and the Z-axis electric cylinder 13 in the X-axis direction, the Y-axis moving frame 12 is used to realize the movement of the Z-axis electric cylinder 13 in the Y-axis direction, and the Z-axis electric cylinder 13 drives the enameled wire spot welding head 21 of the welding assembly 2 to move in the Z-axis direction, which can realize the accurate positioning of the enameled wire spot welding head 21, prevent the enameled wire spot welding head 21 from igniting when it is not in contact with the enameled wire, and prevent the occurrence of empty welding. The welding assembly 2 also includes other components for realizing welding, such as a welding power supply, etc. Other welding components 2 can be set on the frame 5 and electrically connected to the enameled wire spot welding head 21. The enameled wire spot welding head 21 can be any welding head that does not require a paint removal step, and the size of the enameled wire spot welding head 21 can be determined according to the diameter of the enameled wire to be welded.

[0027] The welding platform 3 is plate-shaped and is provided with a mounting groove for mounting the positioning assembly 4 ; the mounting groove is arranged within the moving range of the enameled wire spot welding head 21 .

[0028] Among them, the welding platform 3 can be installed on the frame 5 through a bracket. When installing, the welding platform 3 can determine the relative position with the three-axis driving platform 1 to ensure that the installation slot is within the moving range of the enameled wire spot welding head 21. After the component to be welded is fixed on the positioning component 4, it is fixed in the installation slot as a whole with the positioning component 4, and the positioning between the component to be welded and the three-axis driving platform 1 can be completed. In this embodiment, there is no need to position the component to be welded with the enameled wire spot welding head 21, which reduces the difficulty of positioning, and thus can improve the welding accuracy and processing efficiency.

[0029] like Figure 2 As shown, it is a structural schematic diagram of a positioning component provided in this embodiment, the positioning component 4 is used to position the first component 7 with the enameled wire pin 6 and the second component 8 with the soldering pad, so that the enameled wire pin 6 is positioned directly above the soldering pad.

[0030] Among them, the positioning component 4 can be integral or split. The integral positioning component 4 can first install the second component 8 with the solder pad, and then install the first component 7 with the enameled wire pin 6 above the first component 7, so that the enameled wire pin 6 can be positioned directly above the solder pad. In this embodiment, the positioning component 4 is preferably split, and the split positioning component 4 can include a first component for installing the first component 7, and a second component for installing the second component 8, and a positioning structure is provided between the first component and the second component. After completing the installation of the first component 7 and the second component 8 respectively, the first component and the second component are assembled to complete the positioning work between the first component 7 and the second component 8, so that the enameled wire pin 6 is positioned directly above the solder pad. The second component 8 can be installed using automated equipment, so that the split positioning component 4 can further improve the installation efficiency.

[0031] In summary, the semi-automatic enameled wire pin welding machine provided in this embodiment drives the welding assembly 2 to weld on the welding platform 3 through the three-axis driving platform 1, and positions the components to be welded, thereby improving the positioning accuracy of the enameled wire spot welding head 21 during welding, preventing empty welding, and increasing the service life of the enameled wire spot welding head 21. In addition, semi-automatic welding processing is realized, processing efficiency is improved, and the advantages of high positioning accuracy and good welding quality are achieved.

[0032] like Figure 3 , which is a side view of the three-axis drive platform in this embodiment. In this embodiment, the X-axis moving plate 11 and the Y-axis moving frame 12 each include a base plate, and slide rails 15 are installed in pairs on the two base plates. The slide rails 15 of the X-axis moving plate 11 are vertically arranged with the slide rails 15 of the Y-axis moving frame 12.

[0033] Among them, the three-axis driving platform 1 is guided by two slide rails 15 in the X-axis and Y-axis directions, which can improve the stability and positioning accuracy of the welding assembly 2 moving in the X-axis and Y-axis directions. The X-axis moving plate 11 and the Y-axis moving frame 12 can be driven by a driving device, and the driving device is preferably a screw motor mechanism. The screw motor mechanism is preferably arranged between the two slide rails 15, which can improve the force condition of the two slide rails 15, thereby further improving the movement stability. The screw motor mechanism has high positioning accuracy, which is conducive to preventing empty welding.

[0034] In this embodiment, a slider is provided on the slide rail 15 , and the slider of the X-axis moving plate 11 is connected to the bottom plate of the Y-axis moving frame 12 ; a top plate is installed on the slider of the Y-axis moving frame 12 , and the top plate is connected to the vertical mounting plate 14 through a right-angle connector 16 .

[0035] Among them, the slide rails 15 of the X-axis moving plate 11 and the Y-axis moving frame 12 are both flat, which can improve the stability of the movement. The right-angle connector 16 is preferably a right-angle rib plate, which fixes the top plate and the vertical mounting plate 14 to improve the stability of the vertical installation, prevent the welding assembly 2 from shaking greatly during movement, and improve the positioning accuracy of the enameled wire spot welding head 21, as well as the stability during welding. The bottom plate of the Y-axis moving frame 12 is installed on the slider of the X-axis moving plate 11, which can drive the Y-axis moving frame 12 to move along the X-axis direction as a whole. The top plate is installed on the slider of the Y-axis moving frame 12, which can drive the vertical mounting plate 14 to move along the Y-axis direction, so as to realize the movement and positioning of the welding assembly 2 in the XY plane.

[0036] In this embodiment, a lifting bracket 17 is provided between the bottom plate of the X-axis moving plate 11 and the frame 5 , and the lifting bracket 17 is used to lift the three-axis driving platform 1 so that the enameled wire spot welding head 21 is suspended above the welding platform 3 .

[0037] Among them, the flattened design of the X-axis moving plate 11 and the Y-axis moving frame 12 can improve the movement stability. The welding assembly 2 needs to be docked with the welding platform 3, and the welding assembly 2 needs to be raised to a certain height. Only using the vertical mounting plate 14 to raise the welding assembly 2 will cause the top of the three-axis drive platform 1 to be unstable. Therefore, raising the bottom plate of the X-axis moving plate 11 to a certain height by raising the bracket 17 can further improve the overall stability, reduce the shaking of the welding assembly 2, and improve the positioning accuracy of the enameled wire spot welding head 21.

[0038] like Figure 4 As shown, it is a schematic diagram of the installation of the positioning component of this embodiment on the welding platform. In this embodiment, the positioning component 4 includes a wire hanging plate 41 and a movable clamp; the wire hanging plate 41 is detachably installed in the installation groove of the welding platform 3, the wire hanging plate 41 is used to fix the first component 7 and position the enameled wire pin 6, and a docking hole 42 is provided in the middle of the wire hanging plate 41; the movable clamp is used to fix the second component 8 and position the second component 8 in the docking hole 42.

[0039] Among them, the positioning component 4 is a split type, and the first component 7 is installed on the wire hanging plate 41. The enameled wire pin 6 can be positioned and fixed manually, and then placed in the installation groove of the welding platform 3. The second component 8 can be loaded mechanically, and the second component 8 with the pad is placed face up on the movable fixture by an automated machine, and clamped by the movable fixture. Then, it is transported to the docking hole 42 by the moving function of the movable fixture, so that the pad of the second component 8 is directly below the enameled wire pin 6 of the first component 7, and the positioning is completed. In this embodiment, only the first component 7 needs to be manually installed, which can increase the processing speed.

[0040] like Figure 5As shown, it is a schematic diagram of the structure of the wire hanging board in this embodiment. In this embodiment, the docking hole 42 is in the shape of an elongated strip, the long side of the docking hole 42 is parallel to the Y-axis, and the short side is parallel to the X-axis; a slot 43 for fixing the first element 7 is provided on one side of the long side, and a spring wire clamp 44 for clamping the enameled wire pin 6 and straightening it is provided on the other side; a guide column 45 is also installed on the wire hanging board 41, and the guide column 45 is used to position the straightened enameled wire pin 6 so that the enameled wire pin 6 passes over the docking hole 42 and is parallel to the X-axis.

[0041] Among them, the long strip-shaped docking hole 42 can be convenient for positioning, and the shape of the card slot 43 can be designed according to the first element 7. The shape of the card slot 43 can temporarily fix the first element 7, which is convenient for guiding the enameled wire pin 6 later. As shown in the figure, the first element 7 is a magnetic bar for completing the winding, and the corresponding card slot 43 is a round hole. The card slot 43 and the magnetic bar gap of the first element 7 are matched, which can just clamp the magnetic bar. The depth of the card slot 43 can be preset according to the magnetic bar, so that the enameled wire can be on the surface of the wire hanging board 41 when the magnetic bar is inserted into the card slot 43. In order to ensure the accuracy of welding, the enameled wire pin 6 needs to be straightened into a straight line and kept stable during the welding process.

[0042] In this embodiment, the spring wire clamp 44 includes a dumbbell-shaped body with cylindrical heads at both ends. The middle part of the body can be installed in the through hole set on the wire hanging plate 41. A thrust spring is installed between the head at the lower end of the body and the lower bottom surface of the wire hanging plate 41. The elastic force provided by the spring makes the body tend to move downward, so that the head at the upper end of the body is in close contact with the wire hanging plate 41, clamping the enameled wire pin 6. Before clamping, the enameled wire pin 6 can be manually straightened to facilitate positioning.

[0043] In this embodiment, the guide column 45 is used to guide the enameled wire pin 6 between the card slot 43 and the spring wire clamp 44, so that the enameled wire pin 6 passes over the docking hole 42 and positions it in the docking hole 42. The installation position of the guide column 45 on the wire hanging plate 41 can be designed according to the specific structure of the first element 7 and the second element 8 and the relative position during welding, so that the enameled wire pin 6 passes over the docking hole 42 and is parallel to the X-axis. The guide column 45 is preferably a stepped shaft, and the enameled wire pin 6 can be hung on the shoulder of the guide column 45 and fixed relative to the guide column 45, so that the height of the enameled wire pin 6 on the upper surface of the wire hanging plate 41 is determined, and the positioning of the enameled wire pin 6 in the vertical direction is realized, thereby improving the controllability of the welding process.

[0044] like Figure 6As shown in the figure, it is a schematic diagram of the structure of the movable clamp in the embodiment. In this embodiment, the movable clamp comprises a pair of raised clamps 46, a clamp driving assembly 47 and a YZ moving mechanism 48; the cross-section of the clamp 46 is rectangular, and the long side of the clamp 46 is parallel to the Y-axis; guide rods 49 are installed at the bottom of the two clamps 46, and the clamp driving assembly 47 is used to drive the clamps 46 to open and close along the guide rods 49; the YZ moving mechanism 48 is arranged at the bottom of the clamps 46, and is used to drive the clamps 46 to move to the docking hole 42, and position the pad directly below the enameled wire pin 6.

[0045] Among them, Figure 7 As shown, it is a partial enlarged view of the clamp in the embodiment. The second component 8 is a sheet-like electronic component with a pad, which can be fixed by clamping the two sides of the sheet-like electronic component by a pair of clamps 46. The length of the two clamps 46 when clamping the second component 8 is less than the length of the docking hole 42, so that the clamps 46 can drive the second component 8 to move and fine-tune along the length direction in the docking hole 42, thereby improving the positioning accuracy between the enameled wire pin 6 and the pad. A fixed block can be set at the bottom of the clamp 46, and a guide rod 49 can be installed through the fixed block. The guide rod 49 can be set in pairs to improve the stability of the clamp 46 when moving. The clamp drive assembly 47 can be any driving mechanism such as a cylinder, an electric cylinder or an electric push rod that can drive the two clamps 46 to move along the guide rod 49.

[0046] In this embodiment, a mounting plate is provided at the bottom of the clamping assembly, and is connected to the moving end of the YZ moving mechanism 48 through the mounting plate. The YZ moving mechanism 48 can be any mechanism capable of moving along the Y axis and along the Z axis, preferably an electric cylinder mechanism capable of moving along the Y axis and the Z axis. Not only can the second component 8 be transported to the docking hole 42 along the Y axis, but also the position of the second component 8 in the Y axis and Z axis directions can be adjusted in the docking air, so that the pad is positioned directly below the enameled wire pin 6. The pad is positioned directly below the enameled wire pin 6. During welding, the enameled wire spot welding head 21 directly presses the enameled wire pin 6 downward toward the pad, and the welding step can be completed without manual positioning, which can improve the accuracy of welding and ensure the welding quality.

[0047] Depend on Figure 3 It can be seen that in this embodiment, a frame-shaped bracket 18 is also provided on the vertical mounting plate 14, and a camera 19 with a lens set downward is installed on the frame-shaped bracket 18. The YZ moving mechanism 48 is electrically connected to a fine-tuning device, and the fine-tuning device is used to adjust the positioning position of the second element 8 along the Y-axis direction according to the information recorded by the camera 19.

[0048] The camera 19 is mounted on the vertical mounting plate 14 through a frame-shaped bracket 18, and its position in the Z-axis direction is fixed, which can maintain the shooting distance of the camera 19 and improve the clarity. The fine-tuning device can be an automatic control device or a manual control button, which determines whether the enameled wire pin 6 and the pad are aligned in the Y-axis direction through the image information recorded by the camera 19, and adjusts according to the offset. When the fine-tuning device is a manual control button, it can be equipped with a display screen to display the position of the enameled wire pin 6 and the pad.

[0049] like Figure 8 As shown, it is a schematic diagram of the installation of the feeding mechanism in the embodiment. In this embodiment, it also includes a feeding mechanism 9, which includes a two-axis moving mechanism 91 installed on the frame 5. The moving end of the two-axis moving mechanism 91 is provided with a cantilever 92, and the end of the cantilever 92 is installed with a suction cup 93. The suction cup 93 is used to transfer the second component 8 to between the two clamps 46 and make the soldering pad of the second component 8 face upward.

[0050] Among them, the feeding mechanism 9 can realize the automatic feeding of the second component 8, reduce the labor intensity of manual work, and improve the efficiency of welding processing. The second component 8 can be placed in any container that can lay the second component 8 flat, and the feeding mechanism 9 can take the material from it. Preferably, the container is a material tray. The second component 8 is placed on the material tray with the pad facing up. After the suction cup 93 completes the material taking, the second component 8 is directly moved to the chuck so that the second component 8 can be clamped with the pad facing up. The structure of the cantilever 92 and the suction cup 93 can be designed according to the structure of the second component 8. After the suction cup 93 transfers the second component 8 between the two clamps 46, the chuck drive assembly 47 cooperates with the suction cup 93 to drive the two clamps 46 to move closer to each other and clamp the second component 8.

[0051] In this embodiment, the welding platform 3 is in a "concave" shape, and a protrusion for supporting the hanging wire plate 41 extends toward the center from the inner side of the installation groove; a YZ fine-tuning platform 31 connected to the frame 5 is provided at the bottom of the welding platform 3; and a quick-connect structure is provided at the corresponding position of the installation groove and the hanging wire plate 41.

[0052] Among them, the setting of the mounting groove makes the welding platform 3 present a "concave" shape, with an opening at one end, and the wire hanging plate 41 can be quickly placed in the mounting groove through the opening, which is convenient for placing and taking the wire hanging plate 41 and improving processing efficiency. The welding platform 3 is connected to the frame 5 through the YZ fine-tuning platform 31, which can fine-tune the actual position of the welding platform 3 in the Y-axis and Z-axis directions, facilitate the adjustment of the position during installation, and ensure the positioning accuracy of the welding platform 3. The welding platform 3 can position the wire hanging plate 41 and the movable fixture, thereby improving the positioning accuracy of the first element 7 and the second element 8, and further improving the welding quality. The quick-connect structure can be any kind of quick-fixing structure, such as a snap-on structure. Preferably, the quick-connect structure can be a magnetic buckle set at the corresponding position of the wire hanging plate 41 and the welding platform 3. The magnetic buckle can be set on the periphery of the wire hanging plate 41, and at the position corresponding to the mounting groove of the welding platform 3. When in use, the magnetic buckle can temporarily fix the wire hanging plate 41 on the welding platform 3 by magnetic force, improve the installation stability of the wire hanging plate 41, and the installation position can be more accurate.
