DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See attached Figure 1-11 A chip soldering device in a domain controller includes a positioning plate 1, a cylinder 2 is provided on the positioning plate 1, a lifting plate 3 is connected to the bottom output end of the cylinder 2, a soldering iron 4 is provided on the lifting plate 3, a feeding assembly for conveying tin wire is provided on the lifting plate 3, the feeding assembly includes a first connecting component 51, a tin feeding tube 52 and a feeding unit 53, the first connecting component 51 is arranged on the lifting plate 3, the tin feeding tube 52 and the feeding unit 53 are respectively arranged on both sides of the first connecting component 51, the tin wire passes through the tin feeding tube 52 and one end of the feeding unit 53 is arranged on one side of the soldering head of the soldering iron 4, the cylinder 2 drives the soldering iron 4 and the feeding assembly to move downward synchronously through the lifting plate 3 to perform soldering work, during which the feeding unit 53 conveys the tin wire to the soldering head of the soldering iron 4, the tin wire melts on the soldering head, and the soldering operation can be realized without manual operation.

[0034] In this embodiment, the feeding unit 53 includes two rotating shafts 531 arranged upper and lower, and gears 532 and feed rollers 533 are provided on the two rotating shafts 531. The two gears 532 are meshed and connected with each other, and a gap is provided between the two feed rollers 533 for the tin wire to pass through. When the single rotating shaft 531 rotates, under the action of the two meshing gears 532, the two rotating shafts 531 rotate in opposite directions, further making the two feed rollers 533 rotate in opposite directions. At this time, the tin wire between the two feed rollers 533 moves toward the solder head of the soldering iron 4 and melts on the solder head to facilitate the soldering operation.

[0035] In this embodiment, a ratchet 534 is provided at one end of the lower rotating shaft 531, and a limiting assembly matching the feeding unit 53 is provided on the positioning plate 1. The limiting assembly includes a second connecting component 61 and a limiting unit 62. The limiting unit 62 is connected to the positioning plate 1 through the second connecting component 61, and the limiting unit 62 includes a pawl 621 matched with the ratchet 534. During the process of the cylinder 2 driving the lifting plate 3 to move downward, the position of the positioning plate 1 remains unchanged, and the lifting plate 3 drives the ratchet 534 to move downward through the rotating shaft 531. The ratchet 534 moves downward and its ratchet teeth come into contact with the pawl 621, causing it to rotate. At this time, the ratchet 534 drives the rotating shaft 531 to rotate, further enabling the two feeding rollers 533 to transport the tin wire, and there is no need to add an additional drive to the feeding assembly, which greatly reduces the manufacturing cost of the equipment.

[0036] One side of the pawl 621 is connected to the second connecting component 61 through a spring 622 and a connecting shaft 623. When the lifting plate 3 drives the driving assembly to move upward, the ratchet 534 pushes the pawl 621, causing the pawl 621 to deflect around the connecting shaft 623. When the ratchet 534 exceeds the position of the pawl 621, the pawl 621 is reset under the action of the spring 622. When the soldering iron 4 resets upward, the feed roller 533 does not rotate, thereby preventing the feed roller 533 from rotating in the opposite direction when the soldering iron 4 resets upward and transporting the tin wire backward, affecting subsequent use.

[0037] In this embodiment, the first connecting component 51 includes a first adjusting plate 511, a connecting tube 512 and a supporting plate 513. The first adjusting plate 511 is connected to the lifting plate 3. The connecting tube 512 and the supporting plate 513 are respectively arranged on both sides of the first adjusting plate 511. The connecting tube 512 is sleeved on the outer wall of the tin feeding tube 52. The side of the supporting plate 513 away from the first adjusting plate 511 is rotatably connected to the ends of the two rotating shafts 531. The position and angle of the tin feeding tube 52 and the feeding unit 53 can be adjusted by adjusting the position and angle of the first adjusting plate 511, the connecting tube 512 and the supporting plate 513, and then the angle of the tin wire and the tin feeding can be adjusted, so as to facilitate adaptive adjustment according to different models of soldering irons 4.

[0038] In this embodiment, a circular hole 5111, an arc groove 5112 and a strip groove 5113 are provided on the first adjustment plate 511. The first adjustment plate 511 is connected to the lifting plate 3 through the circular hole 5111, the arc groove 5112 and the bolts. By loosening and tightening the bolts at this position, the angle between the first adjustment plate 511 and the lifting plate 3 can be changed, so as to facilitate the adjustment of the position and angle of the tin feeding tube 52 and the feeding unit 53.

[0039] The first adjustment plate 511 is connected to the connecting tube 512 and the support plate 513 through the strip groove 5113 and bolts. By loosening and tightening the bolts at this position, the angle and position between the support plate 513 and the first adjustment plate 511 can be changed, so as to further adjust the position and angle of the tin feeding tube 52 and the feeding unit 53.

[0040] In this embodiment, the second connecting component 61 includes a fixed plate 611, a second adjusting plate 612 and a connecting plate 613. The top of the fixed plate 611 is connected to the positioning plate 1, the top of the second adjusting plate 612 is connected to the bottom of the fixed plate 611, and its bottom is connected to the top of the connecting plate 613. The connecting plate 613 is connected to the spring 622 and the end of the connecting shaft 623 away from the pawl 621. The position of the connecting shaft 623 and the pawl 621 can be changed by adjusting the position and angle of the second connecting component 61, so that the pawl 621 can cooperate with the ratchet 534. When the position and angle of the first connecting component 51 are changed, the position and angle of the second connecting component 61 can be adaptively changed.

[0041] In this embodiment, the second adjustment plate 612 includes an upper rectangular groove 6121 and a lower rectangular groove 6122. The second adjustment plate 612 is connected to the bottom of the fixed plate 611 through the upper rectangular groove 6121 and bolts. By loosening and tightening the bolts at the position of the upper rectangular groove 6121, it is convenient to adjust the angle and position between the second adjustment plate 612 and the fixed plate 611.

[0042] The second adjustment plate 612 is connected to the top of the connecting plate 613 through the lower rectangular groove 6122 and bolts. By loosening and tightening the bolts at the position of the lower rectangular groove 6122, it is convenient to adjust the angle and position between the connecting plate 613 and the second adjustment plate 612, thereby achieving the effect of adjusting the position and angle of the second connecting component 61.

[0043] In this embodiment, the pawl 621 is provided with a first ratchet tooth 6211 and a second ratchet tooth 6212 that cooperate with the ratchet teeth on the outer wall of the ratchet 534. When the soldering iron 4 is soldering downward, the first ratchet tooth 6211 initially acts on the ratchet teeth of the ratchet 534 to rotate the ratchet 534 by a certain angle. When the soldering iron 4 is soldering downward for the second time, the second ratchet tooth 6212 acts on the ratchet teeth of the ratchet 534 to rotate the ratchet 534 by a certain angle. By alternately cooperating with the ratchet 534, the cooperation between the two is more stable.

[0044] In this embodiment, a track 11 is provided on the positioning plate 1 for the lifting plate 3 to slide up and down, so as to facilitate the lifting plate 3 to move up and down more stably.

[0045] Working principle: the cylinder 2 starts the lifting plate 3 to move downward on the track 11, which further makes the soldering iron 4 and the feeding assembly move downward synchronously. During this process, the ratchet 534 moves downward and is blocked by the pawl 621, causing it to rotate, and drives the feeding roller 533 to rotate through the rotating shaft 531, so that the tin wire passes through the tin feeding tube 52 and the two feeding rollers 533 to approach the solder head of the soldering iron 4 and melt onto the solder head. At this time, the soldering iron 4 completes the soldering work downward without manual soldering, thereby improving the soldering efficiency.

[0046] When the cylinder 2 drives the lifting plate 3 to move upward, the soldering iron 4 and the feeding assembly move upward synchronously. At this time, the ratchet 534 will push the pawl 621 to deflect, and the ratchet 534 will not rotate by itself, thereby preventing the two feeding rollers 533 from rotating in the opposite direction, causing the tin wire to move away from the soldering head of the soldering iron 4 and affecting the next soldering.

[0047] By adjusting the angle and position of the first connecting component 51, the position and angle of the tin feeding tube 52 and the feeding unit 53 can be adaptively changed, which makes it convenient to change the feeding angle and position of the tin wire as needed. By adjusting the angle and position of the second connecting component 61, the position and angle of the limiting unit 62 can be adaptively adjusted according to the feeding angle and position of the tin wire, which makes it convenient to perform soldering operations on different types of chips as needed, thereby greatly improving the use range and practicality of the device.
