Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and specifically to a circular tube welding wire device and system. Background Technology

[0002] With the implementation of global smoking bans, global market analysis reports on e-cigarettes show a continuous increase in sales. The round tube and Litz wire of an e-cigarette require welding. Currently, welding is mostly done manually or semi-automatically. Manual welding is labor-intensive and inefficient, leading to insufficient production capacity and high production costs. Semi-automatic welding typically uses resistance welding equipment. Resistance welding is a welding method that uses the resistance heat generated when current passes through two workpieces under the pressure of two positive and negative electrodes to melt the contact surfaces between the two workpieces, thus achieving a connection. However, existing resistance welding equipment can only weld wire to one preset position on the round tube and cannot weld wire to other positions. If welding is required at multiple different positions, manual adjustment is necessary. Summary of the Invention

[0026] The beneficial effects of the circular tube welding device and system described in this invention are as follows:

[0027] The control mechanism can control the operation of the X-axis motion module, which drives the first frame to move in the X-axis direction. This causes the first Y-axis motion module, the second frame, and the second Z-axis motion module mounted on the first frame to move synchronously in the X-axis direction. The fixture Z-axis adjustment module, lifting module, and round tube placement module mounted on the second frame also move synchronously in the X-axis direction. When moving to the round tube supply device in the X-axis direction, the control mechanism controls the first Y-axis motion module to drive the second frame to move in the positive Y-axis direction. This causes the round tube placement module mounted on the second frame to move in the Y-axis direction, allowing the round tube to be welded to fit into the product positioning rod. The first Y-axis motion module then drives the second frame to move in the opposite Y-axis direction, resetting the product positioning rod. The control mechanism can also control the operation of the X-axis motion module, moving it in the X-axis direction to the wire supply device, and adjusting the fixture Z-axis... The Z-axis adjustment mechanism of the section module drives the sliding side plate to move in the Z-axis direction. Since the round tube mounting module is installed on the sliding side plate, the product positioning rod of the round tube mounting module will also move synchronously. The product positioning rod moves until the round tube contacts the wire. Then, the first Z-axis motion module of the lifting module drives the positioning component to position the round tube to be welded. The control mechanism controls the second Z-axis motion module to drive the welding head of the welding module to move in the Z-axis direction to contact the wire and the round tube and perform resistance welding. After the welding at this position is completed, the control mechanism controls the second Z-axis motion module to drive the welding head of the welding module to reset. The control mechanism controls the rotary motor to drive the product positioning rod to rotate a certain angle, so that the round tube also rotates by the same angle. The wire supply device provides the wire. The control mechanism controls the second Z-axis motion module to drive the welding head of the welding module to move in the Z-axis direction to contact the wire and the round tube at another position and perform resistance welding.

[0059] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0060] like Figures 1 to 14As shown, this embodiment of the invention discloses a circular tube welding device, including a worktable 1, a control mechanism 2, an X-axis motion module 3, a first frame 4, a first Y-axis motion module 5, a second frame 6, a fixture Z-axis adjustment module 7, a lifting module 8, a circular tube placement module 9, a second Z-axis motion module 10, and a welding module 11; the control mechanism 2 is mounted on the worktable 1; the X-axis motion module 3 is mounted on the worktable 1 along the X-axis direction, and the X-axis motion module 3 is electrically connected to the control mechanism 2; the first frame 4 includes a first base plate 41, a first top plate 42, and a connection between the first base plate 41 and the... The first top plate 42 has a first side plate 43 and a first bottom plate 41 that are drive-connected to the X-axis motion module 3; the first Y-axis motion module 5 is mounted on the bottom plate along the Y-axis direction and is electrically connected to the control mechanism 2; the second frame 6 includes a second bottom plate 61 and a second side plate 62 connected to the second bottom plate 61, and the second bottom plate 61 is drive-connected to the first Y-axis motion module 5; the fixture Z-axis adjustment module 7 includes a Z-axis adjustment mechanism 71 and a sliding side plate 72, the Z-axis adjustment mechanism 71 is mounted on the second bottom plate 61 and is electrically connected to the control mechanism 2, and the sliding side plate 72... Plate 72 is slidably connected to the second side plate 62, and the sliding side plate 72 is drive-connected to the Z-axis adjusting mechanism 71; the lifting module 8 includes a first Z-axis motion module 81 and a positioning component 82. The first Z-axis motion module 81 is installed on the sliding side plate 72 along the Z-axis direction. The first Z-axis motion module 81 is electrically connected to the control mechanism 2, and the first Z-axis motion module 81 is drive-connected to the positioning component 82; the round tube placement module 9 is installed on the sliding side plate 72. The round tube placement module 9 includes a product positioning rod 91 and a rotating motor 92. The rotating motor 92 is electrically connected to the control mechanism 2. The positioning rod 91 is connected to the rotating motor 92 for transmission, and the round tube 12 is sleeved on the product positioning rod 91; the second Z-axis motion module 10 is installed on the first top plate 42 along the Z-axis direction, and the second Z-axis motion module 10 is electrically connected to the control mechanism 2; the welding module 11 includes a welding machine 111 and a welding head 112, the welding machine 111 is connected to the second Z-axis motion module 10 for transmission, the welding machine 111 is electrically connected to the welding head 112 and the product positioning rod 91, the welding head 112 and the product positioning rod 91 are electrically opposite, and the welding head 112 and the product positioning rod 91 cooperate to weld the round tube 12 and the wire.

[0061] Control mechanism 2 can control the operation of X-axis motion module 3. X-axis motion module 3 can drive the first frame 4 to move in the X-axis direction, thereby causing the first Y-axis motion module 5, the second frame 6, and the second Z-axis motion module 10 mounted on the first frame 4 to move synchronously in the X-axis direction. The fixture Z-axis adjustment module 7, the lifting module 8, and the round tube placement module 9 mounted on the second frame 6 also move synchronously in the X-axis direction. When moving in the X-axis direction to the round tube 12 device, control mechanism 2 controls... The first Y-axis motion module 5 operates, driving the second frame 6 to move in the positive Y-axis direction. This causes the round tube placement module 9, mounted on the second frame 6, to move in the Y-axis direction, allowing the round tube 12 to be welded to fit into the product positioning rod 91. The first Y-axis motion module 5 then drives the second frame 6 to move in the opposite Y-axis direction, resetting the product positioning rod 91. The control mechanism 2 controls the X-axis motion module 3 to move in the X-axis direction to the wire supply device, driving the Z-axis adjustment mechanism 71 of the fixture Z-axis adjustment module 7. As the sliding side plate 72 moves in the Z-axis direction, the product positioning rod 91 of the round tube 12 mounting module will also move synchronously due to the round tube 12 mounting module being installed on the sliding side plate 72. The product positioning rod 91 moves until the round tube 12 contacts the wire, and then the positioning component 82 is driven by the first Z-axis motion module 81 of the lifting module 8 to position the round tube 12 to be welded. The control mechanism 2 controls the second Z-axis motion module 10 to drive the welding head 112 of the welding module 11 to move in the Z-axis direction until it contacts the wire and the round tube. 12. After resistance welding is performed at this position, the control mechanism 2 controls the second Z-axis motion module 10 to drive the welding head 112 of the welding module 11 to reset. The control mechanism 2 controls the rotary motor 92 to drive the product positioning rod 91 to rotate at a certain angle, so that the round tube 12 also rotates at the same angle. The wire supply device provides the wire. The control mechanism 2 controls the second Z-axis motion module 10 to drive the welding head 112 of the welding module 11 to move in the Z-axis direction to contact the wire and the round tube 12 at another position and perform resistance welding.

[0062] It should be noted that the X-axis motion module 3, the first Y-axis motion module 5, the Z-axis adjustment mechanism 71, the first Z-axis motion module 81, the second Z-axis motion module 10, and the second Y-axis motion module 131 can be electric cylinders or pneumatic cylinders. The welding machine 111 can be a resistance welding machine. The first Z-axis motion module 81 is mounted on the sliding side plate 72 via a pad 83.

[0063] In some embodiments, such as Figure 7-11As shown, the circular tube mounting module 9 also includes a housing 93, a first rotating wheel 94, a second rotating wheel 95, a transmission belt 96, a clamp tube 97, a clamp sleeve 98, a clamp tube 99, a first wheel 910, and a second wheel 911. The housing 93 is fixedly connected to the sliding side plate 72, and the rotating motor 92 is fixedly connected to the housing 93. The transmission shaft of the rotating motor 92 passes through the first through hole of the housing 93 and is connected to the first rotating wheel 94. The second rotating wheel 95 is connected to the first rotating wheel 94 via the transmission belt 96. The first rotating wheel 94, the second rotating wheel 95, and the transmission belt 96 are housed inside the housing 93. One end of the clamp tube 97 passes sequentially through the second through hole of the housing 93, the third through hole of the sliding side plate 72, and the fourth through hole of the first wheel 910. The first wheel 910 is fixed to the clamp tube 97. The second wheel 911 is fixed to the first end of the chuck tube 97 and embedded in the third through hole. The second wheel 911 is electrically connected to the welding machine 111. The other end of the chuck tube 97 passes through the fifth through hole of the second rotating wheel 95. The second end of the chuck tube 97 is a chuck with a groove 971. The side of the groove 971 has at least two slots 972. The product positioning rod 91 is nested into the groove 971. The chuck sleeve 98 is fitted onto the chuck. The clamp tube 99 abuts against the second end. The inside of the clamp tube 99 has a first protrusion 991. The side of the product positioning rod 91 has a first recess 913. The first protrusion 991 and the first recess 913 are engaged. The outside of the clamp tube 99 has a second recess 992. The outside of the round tube 12 has a second protrusion 121. The second recess 992 and the second protrusion 121 are engaged.

[0064] When the rotating motor 92 rotates, the first rotating wheel 94, which is connected to the drive shaft of the rotating motor 92, rotates synchronously. The rotation of the first rotating wheel 94 drives the second rotating wheel 95 to rotate synchronously via the drive belt 96. The rotation of the second rotating wheel 95 drives the chuck tube 97 to rotate. The product positioning rod 91 is nested into the groove 971 of the chuck tube 97. Because the side of the groove 971 has at least two slots 972, the chuck can be tightened by the chuck sleeve 98, thereby fixing the product positioning rod 91. The first protrusion 991 inside the clamp tube 99 engages with the first recess 913 on the side of the product positioning rod 91. When the product positioning rod 91 rotates, the clamp tube 99 also rotates synchronously. The second recess 992 on the outside of the clamping tube 99 engages with the second protrusion 121 on the outside of the round tube 12. When the clamping tube 99 rotates, the round tube 12 also rotates synchronously. Because the round tube 12 can rotate, the welding point on the side of the round tube 12 corresponding to the welding head 112 can be changed, thus enabling the welding head 112 to weld at multiple different positions on the side of the round tube 12. The first wheel 910 embedded in the third through hole makes the rotation of the product positioning rod 91 more stable. The second wheel 911 is electrically connected to the welding machine 111, so the product positioning rod 91, which is fixedly connected to the second wheel 911, can cooperate with the welding head 112 to complete the welding of the round tube 12 and the wire.

[0065] In some embodiments, such as Figure 7 As shown, the circular tube mounting module 9 also includes a first detection sensor 912, which is mounted on the top of the sliding side plate 72. The first detection sensor 912 is connected to the control mechanism 2 via a signal. The edge of the second wheel 911 is provided with a protrusion, which is detected by the first detection sensor 912.

[0066] By setting a protrusion on the edge of the second disc 911, the first detection sensor 912 can detect the rotation angle of the round tube 12 when the rotating motor 92 drives the second disc 911 to rotate, and feed it back to the control mechanism 2. The control mechanism 2 can understand the angle of the welding line relative to the round tube 12.

[0067] In some embodiments, such as Figure 6 As shown, the positioning component 82 includes a movable seat 821, an adjusting seat 822, and a first fork 8224. The movable seat 821 is connected to the first Z-axis motion module 81 via a transmission. The first fork 8224 is fixedly connected to the movable seat 821. The adjusting seat 822 includes a sliding member 8221, an adjusting shaft 8222, and a second fork 8223. The sliding member 8221 is fixedly connected to the movable seat 821. The second fork 8223 is slidably connected to the sliding member 8221. One end of the adjusting shaft 8222 is connected to the second fork 8223. The other end of the adjusting shaft 8222 is provided with a knob 8226 and is installed on the fixing part 8225 of the sliding member 8221.

[0068] The movable seat 821 in the positioning assembly 82 is connected to the first Z-axis motion module 81 via a transmission connection. Therefore, the first Z-axis motion module 81 can drive the movable seat 821 to move in the Z-axis direction, and at the same time, it will also drive the first fork 8224, which is fixedly connected to the movable seat 821, to move in the Z-axis direction. After contacting the clamp 99 of the round tube placement module 9, it positions the clamp 99. The sliding member 8221 of the adjusting seat 822 is fixedly connected to the movable seat 821. A slide rail is provided on the sliding seat, and the second fork 8223 is slidably connected to the sliding member 8221 through the slide rail. The user can move the second fork 8223 in the Z-axis direction by turning the knob 8226, thereby changing the distance between the second fork 8223 and the product positioning rod 91. The second fork 8223 is used to position the round tube 12 on the product positioning rod 91 in the Z-axis direction, thereby ensuring the accurate position of the welding point. Because the diameter of the round tube 12 may change, an adjustment seat 822 is provided so that the height difference between the first fork 8224 and the second fork 8223 can be adjusted, making the round tube welding device suitable for round tubes 12 of various diameters.

[0069] In some embodiments, such as Figure 7 As shown, it also includes a stripping module 13, which includes a second Y-axis motion module 131 and a third fork 132. The second Y-axis motion module 131 is mounted on the sliding side plate 72 along the Y-axis direction. The second Y-axis motion module 131 and the third fork 132 are connected by transmission. The second Y-axis motion module 131 is electrically connected to the control mechanism 2. The fork of the third fork 132 is set on the product positioning rod 91.

[0070] By setting up the stripping module 13, after the round tube 12 is welded to the Litz wire, the resistance welding controller 22 of the control mechanism 2 controls the second Y-axis motion module 131 of the stripping module 13 to work. The second Y-axis motion module 131 can drive the third fork 132 to move in the Y-axis direction, thereby pushing out the round tube 12 with the welded wire that is sleeved on the product positioning rod 91. Among them, the outer periphery of the clamping tube 99 has a concave part in the middle, making the clamping tube 99 an "I" tube. The third fork 132 is inserted into the middle of the clamping tube 99, so that the second Y-axis motion module 131 moves in the positive direction of the Y-axis, and the clamping tube 99 pushes out the round tube 12. After pushing out the round tube 12, the second Y-axis motion module moves in the opposite direction of the Y-axis, and the clamping tube 99 resets. Meanwhile, the second Y-axis motion module 131 and the round tube placement module 9 are both installed on the sliding side plate 72. Therefore, the stripping module 13 and the round tube placement module 9 will move synchronously, ensuring that the third fork 132 can always cooperate with the tube clamp 99.

[0071] In some embodiments, such as Figure 1As shown, it also includes a first auxiliary guide rail 14 and a second auxiliary guide rail 15. The first auxiliary guide rail 14 is installed on the worktable 1 along the X-axis direction. The first frame 4 also includes a first sliding block 44, which is installed on the bottom of the first base plate 41 and is slidably connected to the first auxiliary guide rail 14. The second auxiliary guide rail 15 is installed on the top of the first base plate 41 along the Y-axis direction. The second frame 6 also includes a second sliding block 63, which is installed on the bottom of the second base plate 61 and is slidably connected to the second auxiliary guide rail 15.

[0072] The X-axis motion module 3 can drive the first frame 4 to move along the X-axis direction. The first Y-axis motion module 5, the second frame 6, the fixture Z-axis adjustment module 7, the lifting module 8, the round tube placement module 9, the second Z-axis motion module 10, and the welding module 11 are all set on the first frame 4. Therefore, in order to make the movement of the X-axis motion module 3 more stable, the first auxiliary guide rail 14 is installed on the worktable 1, and the first sliding block 44 is set at the bottom of the first frame 4. The sliding connection between the first sliding block 44 and the first auxiliary guide rail 14 increases the force points, so that the X-axis motion module 3 can better and more evenly distribute the force applied by the first frame 4 and the components installed on the first frame 4, and ensure the stability of the first frame 4 when sliding.

[0073] The first Y-axis motion module 5 can drive the second frame 6 to move along the Y-axis direction. The fixture Z-axis adjustment module 7, lifting module 8, and round tube placement module 9 are all located on the second frame 6. Therefore, in order to make the movement of the first Y-axis motion module 5 more stable, a second auxiliary guide rail 15 is installed on the top of the first base plate 41 along the Y-axis direction, and a second sliding block 63 is set at the bottom of the second frame 6. The second sliding block 63 is slidably connected to the second auxiliary guide rail 15, thereby increasing the force points and allowing the first Y-axis motion module 5 to better and more evenly distribute the force applied by the second frame 6 and the components installed on the second frame 6, thus ensuring the stability of the second frame 6 when sliding.

[0074] In some embodiments, such as Figure 3 and Figure 4 As shown, the sliding side plate 72 is provided with a test piece 73, and the second side plate 62 is provided with a plurality of second detection sensors 74. The plurality of second detection sensors 74 are arranged along the Z-axis direction. The test piece 73 cooperates with the second detection sensors 74, and the second detection sensors 74 are signal connected to the control mechanism 2.

[0075] By providing a test piece 73 on the sliding side plate 72 and multiple second detection sensors 74 arranged along the Z-axis on the second side plate 62, when the sliding side plate 72 is driven to move along the Z-axis by the Z-axis adjustment mechanism 71, the control mechanism 2 can determine the position of the sliding side plate 72 based on the signal fed back by the second detection sensors 74 through the cooperation between the test piece 73 and the second detection sensors 74. It is understood that the second detection sensors 74 can be magnetoelectric sensors, infrared sensors, laser sensors, etc.

[0076] In some embodiments, such as Figure 2 As shown, the control mechanism 2 includes a control frame 21, a resistance welding controller 22, a cable chain 23, and a bellows assembly 24. The control frame 21 is mounted on the workbench 1, the resistance welding controller 22 is mounted on the control frame 21, the cable chain 23 is mounted on the workbench 1 along the X-axis, and the cable chain 23 is located below the control frame 21. The first frame 4 also includes a fixing member 45. One end of the cable chain 23 is fixedly connected to the fixing member 45. The bellows assembly 24 includes a bellows 241, a first mounting member 242, and a second mounting member 243. The first mounting member 242 is mounted on the control frame 21, and the second mounting member 243 is mounted on the first frame 4. One end of the bellows 241 is fixed to the first mounting member 242, and the other end of the bellows 241 is fixed to the second mounting member 243.

[0077] The resistance welding controller 22 is electrically connected to the X-axis motion module 3, the first Y-axis motion module 5, the Z-axis adjustment mechanism 71, the first Z-axis motion module 81, the rotary motor 92, the second Z-axis motion module 10, the welding machine 111, and the second Y-axis motion module 131 via wires. Simultaneously, the resistance welding controller 22 is signal-connected to the first detection sensor 912, enabling it to control the operation of the resistance welding controller X-axis motion module 3, the first Y-axis motion module 5, the Z-axis adjustment mechanism 71, the first Z-axis motion module 81, the rotary motor 92, the second Z-axis motion module 10, the welding machine 111, and the second Y-axis motion module 131. A cable chain 23 is mounted on the worktable 1 along the X-axis direction. The cable chain 23 is located below the control frame 21, and the first frame 4 also includes a fixing member 45. One end of the cable chain 23 is fixedly connected to the fixing member 45. When the X-axis motion module 3 drives the first frame 4, the cable chain 23 also rotates accordingly, thus limiting the cable routing of the X-axis motion module 3. The first mounting component 242 of the corrugated pipe 241 module is mounted on the control frame 21, and the second mounting component 243 is mounted on the first frame 4. The corrugated pipe 241, which is fixed to the first mounting component 242 and the second mounting component 243 respectively, can be used to restrict the wiring between the resistance welding controller 22 and the first Y-axis motion module 5, Z-axis adjustment machine 71, first Z-axis motion module 81, rotary motor 92, second Z-axis motion module 10, welding machine 111, and second Y-axis motion module 131. The corrugated pipe 241 and the cable chain 23 are used to prevent the wiring from affecting the movement of each motion module in the round pipe welding device.

[0078] In some embodiments, such as Figure 1 and Figure 13 As shown, it also includes a detection module 16, which is located on one side of the welding module 11. The detection module 16 includes a third base plate 161, a third side plate 162, a camera 163, and a light source 164. The third base plate 161 is connected to the third side plate 162 and is mounted on the first top plate 42. The camera 163 and the light source 164 are mounted on the third side plate 162. The camera 163 is located above the light source 164. Both the camera 163 and the light source 164 are electrically connected to the control mechanism 2.

[0079] The camera 163 and the light source 164 can be fixed to one side of the welding module 11 via the third base plate 161 and the third side plate 162. The camera 163 can capture whether the wire is in place before welding and provide feedback to the control structure. Before the wire is in place, the control mechanism 2 will not drive other components to work; after the wire is in place, the control mechanism 2 will drive other components to work. At the same time, this embodiment has a light source 164 located below the camera 163, which can provide exposure for the camera 163 in low light conditions, ensuring that the camera 163 can clearly capture the condition of the wire.

[0080] It should be noted that the third side plate 162 is equipped with a fixing claw. The light source 164 is fixed to the column, and the fixing claw holds the column. The operator can adjust the illumination direction of the light source 164 by rotating the column. It is understood that the fixing claw can be slidably connected to the third side plate 162. The third side plate 162 is provided with a slot, and the base of the fixing claw is provided with a screw hole. A nut and washer are provided on the side facing away from the fixing claw. Screws are passed through the screw hole, the slot, and the nut and washer in sequence and tightened for fixation. Loosening the screws and nut and washer allows adjustment of the height of the fixing claw through the slot, thereby adjusting the height of the light source 164. It is understood that the light source 164 can be an LED light, and the camera 163 can be a CDD camera 163.

[0081] The present invention also provides a circular tube welding system, including the above-mentioned circular tube welding device, a circular tube 12 supply device and a wire supply device. The circular tube 12 supply device provides the circular tube 12 to be welded to the circular tube 12 welding device, and the wire supply device provides the wire to be welded to the circular tube 12 welding device.

[0082] Because the circular tube welding system of the present invention uses the above-mentioned circular tube welding device, it can weld multiple different positions of the circular tube 12 without manual intervention, making the welding of the circular tube 12 completely automated, saving manpower. At the same time, mechanical adjustment of position is more accurate and more efficient than manual adjustment.

[0083] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
