Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, specifically to an infrared receiver head wire bonding device. Background Technology

[0002] The infrared receiver head wire bonding device is used to ensure the reliable and fixed welding connection between the infrared receiver head and the wire to form an electrical path. The device can position and clamp the infrared receiver head to keep it stable during welding, while feeding solder to the welding area. The welding is completed by heating, which replaces manual operation to achieve mass production, improves welding efficiency and quality stability, reduces problems such as poor welding and desoldering, and ensures the reliability and consistency of the connection between the infrared receiver head and the wire.

[0003] In the prior art, an automatic welding device with infrared positioning, disclosed in patent publication number CN221473981U, includes a body and a switch. The body houses a first motor connected to a first lead screw, with a first slider at one end of the lead screw. Because the infrared emitter is tilted, it does not affect the welding torch in front. The device adjusts the rotating block via a rotating shaft, and then rotates the rotating arm again via the rotating shaft, lowering the welding torch below the rotating arm so that the torch contacts the workpiece to be welded, completing the welding process. Simultaneously, a second push rod moves a moving block back and forth, causing the rotating block in front to move, facilitating adjustment of the rotating arm for welding at different positions.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Example: An infrared receiver head wire bonding device, see attached diagram. Figure 1 -Appendix Figure 7 ,include,

[0034] The wire bonding device body 100 includes a fixing frame 110, a guide rail 120 adapted to be installed on the top of the fixing frame 110, a welding material 130 located inside the guide rail 120, a positioning plate 140 set directly above the guide rail 120 and used in conjunction with the welding material 130, a plurality of welding heads 150, and a heating block 160 fixedly installed on the fixing frame 110.

[0035] It should be noted that the fixing frame 110 is used to ensure the overall structural stability of the wire bonding device body 100, the guide rail 120 is used to guide the positioning and movement of the infrared receiver head to be welded and the welding material 130, ensuring that they are in the correct position during welding, the welding material 130 is used to provide solder and other materials for the infrared receiver head, the positioning plate 140 can be moved vertically by an external robotic arm, thereby assisting in fixing the position of the welding material 130 on the guide rail, the welding head 150 is used to heat the welding part, so that the solder melts and the welding is completed, and the heating block 160 can heat up after being powered on, preheating the welding material 130 through heat conduction. The wire bonding device body 100 is existing technology, and this solution will not describe it in detail, and those skilled in the art can clearly understand its working principle.

[0036] The adjustment mechanism 200 includes a pitch-changing assembly 210 for horizontal pitch-changing movement of multiple welding heads 150, and a lifting assembly 220 for controlling vertical displacement of multiple welding heads 150.

[0037] The pitch control assembly 210 is located below the positioning plate 140, and the lifting assembly 220 is located outside the pitch control assembly 210.

[0038] The pitch-changing assembly 210 includes a rotating rod 211 rotatably connected to the inner surface of the positioning plate 140, a first bevel gear 212 fixedly sleeved on the outer end face of the rotating rod 211, a second bevel gear 213 meshing with the outer surface of the first bevel gear 212, and a transmission column 214 fixedly connected to the inner surface of the second bevel gear 213.

[0039] Specifically, the pitch conversion assembly 210 also includes multiple arc grooves 215 respectively opened on both sides of the transmission column 214, a force-bearing column 216 disposed inside the arc groove 215, a slider 217 fixedly connected to the outer end face of the force-bearing column 216, and a guide rod 218 fixedly installed on the bottom of the positioning plate 140 and used in conjunction with the slider 217.

[0040] It should be noted that when the rotating rod 211 drives the first bevel gear 212 to rotate, the first bevel gear 212 and the second bevel gear 213 cooperate to drive the transmission column 214 and the arc groove 215 to rotate synchronously. The arc groove 215 pushes the force-bearing column 216, causing the slider 217 to slide horizontally along the guide rod 218, thereby driving the horizontal spacing adjustment of the welding heads 150 of the lifting assembly 220.

[0041] Preferably, a rotating bearing sleeve is installed at the connection between the transmission column 214 and the positioning plate 140, the inner wall of the arc groove 215 slides in contact with the outer surface of the force-bearing column 216, and the slider 217 is slidably sleeved on the outer surface of the guide rod 218.

[0042] When the drive column 214 rotates, it can drive multiple force-bearing columns 216 and sliders 217 to move horizontally with varying pitch along the outer surface of the guide rod 218 through the arc groove 215.

[0043] Furthermore, the lifting assembly 220 includes a rotating column 221 rotatably connected to the inner surface of the slider 217, a threaded rod 222 fixedly installed at the through end of the rotating column 221, and an internal threaded block 223 threadedly connected to the outer surface of the threaded rod 222 and used in conjunction with the welding head 150.

[0044] It should also be noted that when the rotating column 221 rotates, it can drive the threaded rod 222 to rotate synchronously, so that the internal thread block 223 can move vertically through the rotation of the threaded rod 222, thereby driving the welding head 150 to rise and fall.

[0045] It should be noted that multiple welding heads 150 are respectively adapted to be installed on the outer side of multiple internal threaded blocks 223, the outer end face of the threaded rod 222 is fixedly installed on the inner wall of the slider 217 by a shaft, and the outer surface of the internal threaded block 223 slides in contact with the inner wall of the slider 217.

[0046] Furthermore, the adjustment mechanism 200 also includes a drive assembly 230 for flexibly controlling the rotation of the rotating rod 211 and the rotating column 221 to drive the welding head 150 to make horizontal pitch movement or vertical displacement.

[0047] They are respectively located on the outside of the positioning plate 140 and the slider 217.

[0048] Specifically, the drive assembly 230 includes a first fixed magnet 231 fixedly connected to the top of the positioning plate 140, and a first movable magnet 232 fixedly sleeved on the outer surface of the rotating rod 211 and used in conjunction with the first fixed magnet 231.

[0049] Preferably, the drive assembly 230 further includes a second fixed magnet 233 fixedly connected to the bottom of the slider 217, and a second movable magnet 234 fixedly sleeved on the outer surface of the rotating column 221 and used in conjunction with the second fixed magnet 233.

[0050] It should be explained that, through the cooperation of the first fixed magnet 231 and the first movable magnet 232, the magnetic coupling can be controlled by an external circuit to drive the rotating rod 211 to rotate, thereby controlling the welding head 150 to move horizontally with varying pitch. Through the cooperation of the second fixed magnet 233 and the second movable magnet 234, the magnetic coupling can be controlled by an external circuit to drive the rotating column 221 to rotate, thereby controlling the welding head 150 to move vertically up and down. Electromagnetic coupling is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand its working principle.

[0051] When using,

[0052] The infrared receiver head and welding material 130 are placed on the guide rail 120 and guided by the guide rail 120 to move below the positioning plate 140. Then, the positioning plate 140 is moved vertically by an external robotic arm to help fix the position of the welding material 130 on the guide rail. The welding material 130 provides solder and other materials to the infrared receiver head.

[0053] During this process, the heating block 160 is energized and heats up, preheating the welding material 130 through heat conduction;

[0054] The magnetic coupling between the first fixed magnet 231 and the first movable magnet 232 is controlled by an external circuit, causing the first movable magnet 232 to drive the rotating rod 211 to rotate. The rotating rod 211 drives the first bevel gear 212 and the second bevel gear 213 to rotate. The second bevel gear 213 then drives the transmission column 214 to rotate, causing the transmission column 214 to push the force-bearing column 216 through the arc groove 215, thereby driving the slider 217 to slide horizontally along the guide rod 218. This adjusts the horizontal spacing of the multiple welding heads 150 to accommodate infrared receiver head pins with different spacing.

[0055] Subsequently, the magnetic coupling between the second fixed magnet 233 and the second movable magnet 234 is controlled by an external circuit. The second movable magnet 234 drives the rotating column 221 to rotate, and the rotating column 221 drives the threaded rod 222 to rotate. This causes the internal thread block 223 to move vertically along the inner wall of the threaded rod 222 through the rotation of the threaded rod 222, thereby driving the welding head 150 to rise and fall to a suitable welding position.

[0056] Then, the welding head 150 is controlled to heat the welding area, so that the solder and other welding materials 130 melt, completing the welding of the infrared receiver head and the wire. After the welding is completed, the welding head 150 is reset by the reverse control external circuit so that the next welding operation can be continued.

[0057] In summary, by setting the adjustment mechanism 200, precise automated control can be achieved for the horizontal pitch movement or vertical displacement of the welding head 150, adapting to infrared receivers with different pin spacing and heights. This significantly improves the device's adaptability to products of various specifications, thereby greatly enhancing the positioning accuracy of the welding head 150 while meeting the production needs of rapid product upgrades.

[0058] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
