Description

Technical Field

[0001] The present invention relates to the technical field of heating wire welding, and particularly to a heating wire welding device. Background Art

[0002] Among numerous electronic devices and electrical products in industrial, household, and special fields, heating wires are extremely crucial heating elements. Their core function is to efficiently convert electrical energy into heat energy to meet various heating requirements. For example, in household appliances such as electric heaters, ovens, and dryers, heating wires generate heat when powered on, providing a warm and dry environment for indoor spaces or items; in the industrial production field, like plastic molding equipment and metal heat treatment equipment, heating wires are an indispensable part of processes such as material heating, softening, and melting; in addition, in some special environments or devices, such as heating components in the aerospace field and disinfection heating devices in medical equipment, heating wires also play a vital role, ensuring the normal operation of related processes or devices.

[0003] During the current heating wire welding, when manually operating the wire to wind and weld the heating wire, it is very difficult to meet the standards of neatness, tightness, and integrity, resulting in unstable welding quality, increased contact resistance, and affecting the electrical energy transmission efficiency. Moreover, most of the existing welding methods require separately winding and welding the wires at both ends of the heating wire, which not only increases the processes and operation difficulty, reduces the production efficiency, but also easily introduces more errors due to multiple operations, further affecting the welding quality. Therefore, the present invention proposes a heating wire welding device. Summary of the Invention

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The present invention can firmly clamp the wire through the rotary clamping mechanism. Then, the pneumatic push rod of the pressing mechanism drives the pressing plate to tightly press the wire and the pin ends of both ends of the heating wire together, providing a good foundation for subsequent welding. Then, in cooperation with the first driving mechanism and the rotary clamping mechanism, the ends of the two sides of the wire are evenly wound around the pin ends of both ends of the heating wire. The welding mechanism welds the connection between the wire and the heating wire. The entire welding process has a high degree of automation, reduces the welding quality problems caused by inaccurate manual operation, effectively reduces the contact resistance, thereby ensuring the power transmission efficiency, and improving the production efficiency and product quality.

[0024] 2. In the present invention, through the cooperation of the second driving mechanism and the third driving mechanism with the welding mechanism, through the design of multi-dimensional adjustment, the welding mechanism can adapt to the welding of heating wires and wires with different specifications and shapes, greatly improving the versatility and flexibility of the equipment, and reducing the production cost of enterprises.

[0025] 3. In the present invention, both sides of the wire are used to connect to the two pin ends of the heating wire simultaneously. The first driving mechanism drives the mounting frames on both sides to move towards each other, and the wires on both sides are transported to the appropriate positions at one time. The rotating clamping mechanism evenly winds the ends of the wires on both sides around the pin ends of the heating wire at the same time, reducing the process of manually operating on the pin ends of both ends of the heating wire respectively, thus greatly improving the production efficiency and meeting the requirements of large-scale production.

[0048] Embodiment 1

[0049] As shown in the appendix Figure 1 to the appendix Figure 11 As shown, the present invention provides a heating wire welding device, including a processing table 1. A chute 101 is correspondingly opened on the upper surface of the processing table 1. A first driving mechanism 2 is provided on the top of the processing table 1. Mounting frames 3 are slidably arranged oppositely in the two chutes 101. The first driving mechanism 2 is used to drive the opposite movement of the two mounting frames 3. Rotating clamping mechanisms 4 for clamping wires are provided on both mounting frames 3. On the top of the processing table 1 and in the middle of the two rotating clamping mechanisms 4, a pressing mechanism 7 for pressing the heating wire and the wire is provided. Manipulators 10 for placing and taking the heating wire are provided on the side of the pressing mechanism 7 through adapter plates. A gantry 9 is provided at the rear side of the top of the processing table 1. A second driving mechanism 5 is installed on the front side of the gantry 9. A third driving mechanism 8 is provided on the second driving mechanism 5. The second driving mechanism 5 is used to drive the lifting movement of the third driving mechanism 8. A welding mechanism 6 is connected to the third driving mechanism 8. The welding mechanism 6 is used to weld the welding seams of the heating wires and wires on both sides.

[0050] Embodiment 2:

[0051] As shown in the appendix Figure 3 to the appendix Figure 7 As shown, this embodiment is basically the same as the previous embodiment. The difference is that the first driving mechanism 2 includes ear seats 201 correspondingly arranged on both sides of the top of the processing table 1. A first bidirectional lead screw 202 is installed between the two ear seats 201. The mounting frames 3 are connected by opposite threads on the outer sides of the first bidirectional lead screw 202. One end of the first bidirectional lead screw 202 is connected to a first motor 203.

[0052] Furthermore, a cross frame 301 is provided between the two side plates of the mounting frame 3. An installation groove 302 is opened along the plate body at the top of the cross frame 301. A second motor 303 is fixedly installed on one side of the cross frame 301. The output end of the second motor 303 penetrates into the inside of the installation groove 302 and is fixedly connected to a second bidirectional lead screw 304. First moving blocks 305 are connected by opposite threads on the outer side of the second bidirectional lead screw 304. First connecting members 306 that cooperate with the rotating clamping mechanism 4 are provided on the opposite sides of the two first moving blocks 305.

[0053] Furthermore, the rotary clamping mechanism 4 includes a fixed seat 401 detachably connected to the first connecting member 306 and an arc-shaped rotating plate 402. A limiting rib 403 is provided on the outer side of the arc-shaped rotating plate 402, and the inner side of the limiting rib 403 is slidably engaged with the top side of the fixed seat 401. Two sets of third motors 411 are correspondingly arranged on the bottom side plate of the fixed seat 401. The output ends of the two sets of third motors 411 are both connected with a first gear 405. Teeth 404 meshing with the first gear 405 are provided on the outer side of the limiting rib 403. Fixed grooves 406 corresponding to the limiting rib 403 are provided on the inner side of the arc-shaped rotating plate 402. An annular block 407 is rotatably connected in the fixed groove 406. An arc-shaped connecting rod 408 is annularly arranged on the side end face of the annular block 407 through a pin shaft. The other ends of a plurality of arc-shaped connecting rods 408 are fixedly connected with an intermediate block 409. The other side end points of a plurality of intermediate blocks 409 are jointly rotatably connected with a ring 410. The arc-shaped connecting rod 408 drives the intermediate block 409 to rotate about the ring 410 to realize opening and closing. By rotating the annular block 407, after the annular block 407 rotates, the arc-shaped connecting rod 408 drives the intermediate block 409 to open. The intermediate block 409 rotates along the end connected to the ring 410. The opening and closing of the intermediate block 409 are realized through the rotation of the annular block 407, so as to realize releasing and locking.

[0054] Furthermore, the pressing mechanism 7 includes a support column 701 arranged between the two side mounting frames 3. The top of the support column 701 is connected with an arc-shaped frame 702. A second limiting groove 703 is correspondingly formed on the inner side of the arc-shaped frame 702. A pressing table 704 is arranged at the inner bottom of the arc-shaped frame 702. A semi-circular groove 705 for accommodating a heating wire is arranged at the upper end of the pressing table 704. The semi-circular groove 705 is coaxial with the annular block 407. Two pressing plates 706 are arranged on the top of the pressing table 704. The two pressing plates 706 are arranged in a mirror image with respect to the axis of the semi-circular groove 705, and the lower ends of the two pressing plates 706 are at the same height as the top surface of the semi-circular groove 705. Inner arc surfaces corresponding to the semi-circular groove 705 are formed at the opposite ends of the tops of the two pressing plates 706. Pneumatic push rods 707 are arranged on the opposite sides of the two pressing plates 706. The two side pneumatic push rods 707 are both arranged on a bearing plate 708. The bearing plate 708 is fixed on the inner side of the arc-shaped frame 702 through a tightening member cooperating with the second limiting groove 703. The output ends of the two side pneumatic push rods 707 are fixedly connected to the corresponding pressing plates 706. An extension plate 709 for the pressing plate 706 to slide relatively for a short distance is arranged on the top side of the pressing table 704.

[0055] As described above, first, the robotic arm 10 grips the wire and places it on the rotary clamping mechanism 4. At this time, the annular block 407 in the rotary clamping mechanism 4 starts to rotate, driving the connected arc-shaped connecting rod 408 to move. The arc-shaped connecting rod 408 further drives the middle block 409 to open or close. The middle block 409 rotates along the end connected to the circular ring 410. By the rotation of the annular block 407, the opening and closing of the middle block 409 are realized, thus realizing the functions of releasing and locking the wire, ensuring that the wire is firmly clamped on the rotary clamping mechanism 4. Next, the heating wire is placed in the semi-circular groove 705 on the pressing platform 704 of the pressing mechanism 7. The semi-circular groove 705 is coaxial with the annular block 407, preparing for the subsequent pressing and winding operations. Subsequently, the first motor 203 is started. The first motor 203 drives the first bidirectional lead screw 202 to rotate. Since the mounting brackets 3 are threadedly connected to the outer sides of the first bidirectional lead screw 202 in opposite directions, the two side mounting brackets 3 are driven to move towards each other along the sliding groove 101, and then the wire is conveyed into the inner arc surface formed by the two pressing plates 706, and the wires on both sides are respectively located on the pin ends at both ends of the heating wire, providing the correct position for the subsequent pressing operation. After that, the pneumatic push rods 707 are started. The two pneumatic push rods 707 are both arranged on the bearing plate 708. The bearing plate 708 is fixed by cooperating with the second limiting groove 703 inside the arc-shaped frame 702 through a tightening member. The output ends of the pneumatic push rods 707 are fixedly connected to the corresponding pressing plates 706. The pneumatic push rods 707 drive the two pressing plates 706 to slide relatively for a short distance on the extension plate 709 on the top side of the pressing platform 704, making the two pressing plates 706 approach each other, pressing the wires on both sides and the pin ends at both ends of the heating wire together, ensuring that the wire and the heating wire can be in close contact before welding. After the pressing operation is completed, the third motor 411 is started. The output end of the third motor 411 is connected with a first gear 405. The first gear 405 meshes with the teeth 404 on the limiting protrusions 403 on the outer side of the arc-shaped rotating plate 402. Therefore, when the third motor 411 drives the first gear 405 to rotate, it will further drive the whole arc-shaped rotating plate 402 to rotate. At the same time, in cooperation with the first motor 203 driving the first bidirectional lead screw 202 to rotate, the two side mounting brackets 3 are kept in appropriate positions and movements, so that the ends of the wires on both sides are evenly wound around the pin ends at both ends of the heating wire, preparing for the subsequent welding operation. After the winding operation is completed, the wire and the heating wire connection are welded by the welding mechanism 6 to ensure that the two can be firmly connected together. Finally, the robotic arm 10 removes the welded wire and heating wire.

[0056] Embodiment 3:

[0057] As shown in the attached Figure 8 to the attached Figure 11As shown, this embodiment is basically the same as the previous one, except that the second driving mechanism 5 includes a first driving component 501 and a second driving component 502. The first driving component 501 is symmetrically arranged on the front side of the top of the gantry 9. There are two groups of the second driving components 502 corresponding to the first driving component 501, and the first driving component 501 drives the second driving component 502. The first driving component 501 includes a first fixing plate 5011 arranged on the top side of the gantry 9. A second fixing plate 5013 is correspondingly arranged beside the first fixing plate 5011. First synchronous pulleys 5014 are installed on both the first fixing plate 5011 and the second fixing plate 5013. A first synchronous belt 5015 is wound around the two first synchronous pulleys 5014 on both sides. A spur gear 5012 is coaxially fixedly connected to the first fixing plate 5011 with respect to the first synchronous pulley 5014. The spur gears 5012 on the two first driving components 501 are meshed with each other. One side of the spur gear 5012 is driven by a fourth motor 5016 provided. The second driving component 502 includes a third fixing plate 5021 arranged on the bottom side of the gantry 9 and second synchronous pulleys 5022. The second synchronous pulleys 5022 are respectively installed on the second fixing plate 5013 and the third fixing plate 5021. A second synchronous belt 5023 is wound around the second synchronous pulleys 5022. A moving member 5024 is fixedly arranged on the body of the second synchronous belt 5023. A connecting plate 5025 is arranged on the end face of the moving member 5024. A connecting plate 5026 is also arranged on the side of the moving member 5024. A slide rail 5027 is arranged on the side of the gantry 9. A slider 5028 that is matched with the slide rail 5027 is slidably arranged on the slide rail 5027. The side of the slider 5028 is fixedly connected to one side of the connecting plate 5026. The second synchronous pulley 5022 and the first synchronous pulley 5014 located on the second fixing plate 5013 are coaxial. Specifically, by starting the fourth motor 5016, the spur gear 5012 and the first synchronous pulley 5014 on the same axis rotate synchronously. Since the spur gears 5012 on both sides are meshed with each other, the spur gear 5012 thereon will drive the spur gear 5012 on the other first driving component 501 to rotate synchronously. Thus, by driving the spur gear 5012 on the other side, the rotation of the other first synchronous pulley 5014 is driven, ensuring that the first synchronous pulleys 5014 on the two first driving components 501 rotate synchronously. The first synchronous pulley 5014 on the second fixing plate 5013 is driven to rotate by the first synchronous belt 5015 wound around the outside of the first synchronous pulley 5014. Since the second synchronous pulley 5022 on the second fixing plate 5013 is coaxially arranged with the first synchronous pulley 5014, when the first synchronous pulley 5014 on the same axis rotates, the second synchronous pulley 5022 on the same axis rotates synchronously. The two second synchronous pulleys 5022 rotate synchronously through the second synchronous belt 5023 wound around them. By driving the second synchronous belt 5023, the moving member 5024 thereon is driven to move along the slide rail 5027, thereby driving the third driving mechanism 8 and the welding mechanism 6 to move up and down. During the movement, the slide rail 5027 provides stable track support for the movement of the third driving mechanism 8 and the welding mechanism 6.

[0058] Further, the third driving mechanism 8 includes a frame plate 802. The frame plate 802 is fixedly connected to the side surface of the connecting plate 5025 through second connecting members 801 provided on both sides. A fixing frame 803 is welded to the bottom of the side plate of the frame plate 802. Two groups of guide rods 804 are arranged in parallel in the two fixing frames 803. An electric rail 805 is provided on the bottom surface of the frame plate 802 facing the guide rods 804 along the plate body direction. An electric slider 806 linearly slides on the electric rail 805. Specifically, the welding mechanism 6 is driven by the third driving mechanism 8 to perform linear movement in the horizontal direction.

[0059] Further, the welding mechanism 6 includes an L-shaped block 601 sleeved outside the guide rod 804. A fifth motor 602 is fixedly installed at the top of the L-shaped block 601. The output end of the fifth motor 602 is fixedly connected to a second gear 603. An electric lifting rod 604 is rotatably connected inside the L-shaped block 601. The output end of the electric lifting rod 604 is fixedly connected to a lifting collar 606.

[0060] Working principle: First, the robotic arm 10 precisely clamps the wire and steadily places it on the rotary clamping mechanism 4. The annular block 407 in the rotary clamping mechanism 4 starts to rotate, driving the arc-shaped connecting rod 408 to move. The arc-shaped connecting rod 408 further drives the intermediate block 409 to open or close. By rotating the annular block 407, the opening and closing of the intermediate block 409 are controlled, thereby realizing the functions of releasing and locking the wire, ensuring that the wire is firmly clamped on the rotary clamping mechanism 4. Place the heating wire in the semi-circular groove 705 on the pressing platform 704 of the pressing mechanism 7. The semi-circular groove 705 is coaxial with the annular block 407, preparing for subsequent pressing and winding operations. Start the first motor 203, and the first motor 203 drives the first bidirectional lead screw 202 to rotate. Since the mounting brackets 3 are threadedly connected to the outer sides of the first bidirectional lead screw 202 in opposite directions, the two side mounting brackets 3 are driven to move towards each other along the sliding grooves 101, thereby conveying the wire into the inner arc surface formed by the two pressing plates 706, and making the wires on both sides respectively located on the pin ends at both ends of the heating wire. Start the pneumatic push rod 707, and the pneumatic push rod 707 drives the two pressing plates 706 to slide relatively for a short distance on the extension plate 709 on the top side of the pressing platform 704, making the two pressing plates 706 approach each other and pressing the wires on both sides and the pin ends at both ends of the heating wire together to ensure that the wire and the heating wire are in close contact before welding. Then start the third motor 411, and the third motor 411 drives the first gear 405 to rotate, thereby driving the overall rotation of the arc-shaped rotating plate 402. At the same time, in cooperation with the first motor 203 driving the first bidirectional lead screw 202 to rotate, the two side mounting brackets 3 are kept in appropriate positions and movements, so that the ends of the wires on both sides are evenly wound around the pin ends at both ends of the heating wire. Then, in response to the second driving mechanism 5, start the fourth motor 5016, and the fourth motor 5016 drives the spur gears 5012 and the first synchronous pulleys 5014 on the same axis to rotate synchronously. Since the spur gears 5012 on both sides mesh with each other, the spur gears 5012 on the other driving component 501 will rotate synchronously, thereby driving another group of first synchronous pulleys 5014 to rotate, ensuring that the first synchronous pulleys 5014 on both driving components 501 rotate synchronously. The first synchronous belt 5015 wound around the outside of the first synchronous pulley 5014 drives the first synchronous pulley 5014 on the second fixing plate 5013 to rotate. Since the second synchronous pulley 5022 on the second fixing plate 5013 is coaxially arranged with the first synchronous pulley 5014, when the first synchronous pulley 5014 on the same axis rotates, the coaxial second synchronous pulley 5022 is driven to rotate synchronously. The two second synchronous pulleys 5022 on both sides achieve synchronous rotation through the wound second synchronous belt 5023, and the second synchronous belt 5023 drives the moving member 5024 thereon to move along the slide rail 5027.The moving member 5024 is connected to the frame plate 802 of the third driving mechanism 8 through the connecting plate 5025, thereby driving the third driving mechanism 8 and the welding mechanism 6 to move up and down, roughly moving the welding mechanism 6 to the vicinity of the height area where the wire and the heating wire are connected, making a preliminary positioning for subsequent precise welding. Then, it cooperates with the electric slider 806 linearly sliding on the electric rail 805 of the third driving mechanism 8 to start operating, driving the welding mechanism 6 to linearly move in the horizontal direction, further adjusting the position of the welding mechanism 6 in the horizontal direction to make it closer to the welding point. Then, through the welding mechanism 6, the output end of the fifth motor 602 drives the second gear 603 to rotate. The second gear 603 meshes with the driven gear 605 on the outer surface of the electric lifting rod 604, so that the whole electric lifting rod 604 keeps rotating, driving the lifting collar 606 to rotate, and then the welding head 611 rotates to adjust the orientation of the welding head 611 to meet the welding requirements at different angles. The output end of the electric lifting rod 604 drives the lifting collar 606 to move up and down, which can drive the welding head 611 to move up and down, precisely adjusting the position of the welding head 611 in the vertical direction to make it closer to the welding point. When the welding head 611 is adjusted to the appropriate position, the welding mechanism 6 starts the welding operation to weld the connection between the wire and the heating wire, firmly connecting the two together. After welding, the robotic arm 10 removes the welded wire and heating wire, completing the entire assembly welding process. The design of multi-dimensional adjustment enables the welding mechanism 6 to adapt to the welding of heating wires and wires with different specifications and shapes, greatly improving the versatility and flexibility of the equipment, reducing manual intervention, effectively reducing the contact resistance, thus ensuring the power transmission efficiency, and improving the production efficiency and product quality.
