Description

Technical Field

[0001] The invention relates to the technical field of soldering, in particular to a positioning soldering device for electronic components of a computer mainboard. Background Art

[0002] Soldering is a welding method that uses low-melting-point metal solder to melt and then penetrate and fill the gap between metal parts. Soldering is widely used in the electronics industry and can connect many different types of metal materials. The welding method is simple, low-cost and easy to operate. When processing computer motherboards, soldering technology is used to position and process electronic components. However, existing soldering equipment still has defects and deficiencies in some aspects that need to be improved:

[0003] For example, a positioning soldering device for electronic components of a computer motherboard with application number: CN202211083715.9 includes: a frame, a fixed platform, a lifting device, and a positioning device, wherein the frame carries the soldering device; the fixed platform is fixed on the frame to fix the computer motherboard and has a mobile function; the lifting device is fixed on the frame and is located on one side of the fixed platform; the positioning device is movably arranged on the lifting device, and the first moving arm is provided with a transmission nut in the middle, which is rotatably connected to the transmission screw, and the two sides are slidably connected to the frame in the vertical direction. Driven by the lifting motor and restricted by the frames on both sides, the first moving arm moves up and down on the transmission screw through the transmission nut. Compared with the prior art, the present invention adjusts the welding position and welding angle of the soldering assembly in real time through the arrangement of the displacement assembly and the rotation assembly, and combines the electric soldering iron with the tin bar conveying through the soldering assembly to achieve highly automated coordination and improve the welding quality and efficiency.

[0004] The soldering heads of the soldering equipment in the above documents are mostly fixed vertically downward, and the angle of the soldering heads cannot be adjusted. The soldering heads in fixed positions cannot fully perform soldering processing on components, resulting in certain limitations in soldering.

[0005] For example, the application number is: CN201922390213.0. A soldering device for electronic component production includes a soldering device body, a workbench is provided at the bottom of the soldering device body, a dovetail groove is provided at the top of the front side of the workbench, and an adjusting mechanism used in conjunction with the soldering device is provided in the inner cavity of the dovetail groove. Fixing mechanisms used in conjunction with the adjusting mechanism are provided on the front and rear sides of both sides of the soldering device body, and fixing grooves used in conjunction with the fixing mechanism are provided on both sides of the top of the workbench. The fixing mechanism includes a shell, a first through hole and a second through hole are respectively provided at the top and bottom of the shell, and an adjusting rod is provided in the inner cavity of the shell. The top of the adjusting rod passes through the first through hole and the second through hole and extends to the outside of the shell and is fixedly connected with a pull ring. By arranging a soldering device body, a workbench, a dovetail groove, an adjustment mechanism, an adjustment plate, a slider, a slide groove, a limit groove, a fixing mechanism, a shell, a first through hole, a second through hole, an adjustment rod, a pull ring, a spring, a limit block and a fixing groove for coordinated use, the problem that most of the existing soldering devices for electronic component production do not have a fixing mechanism for the workbench, which causes shaking during soldering and affects the user's use is solved.

[0006] Most of the soldering equipment in the above documents are unable to remove dust from the soldering heads and the required welding objects. When dust adheres to the processing components and the soldering heads, the dust will affect the subsequent soldering operations to a certain extent. At the same time, the existing equipment cannot ensure the uniform outflow of the welding liquid. The soldering heads spray empty liquid during the spraying process, which reduces the processing efficiency.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) The user can place the computer motherboard on the placement table, and then start the electric slide rail, so that the sliding seat moves on the electric slide rail, and synchronously drives the placement table to move. The user can adjust the position of the placement table as needed, so as to position the computer motherboard. After the placement table position adjustment is completed, the user starts the electric slide seat, and the electric slide seat drives the soldering head to move downward, thereby completing the soldering operation;

[0029] (2) When the user turns the handle, the handle can drive the bidirectional threaded rod to rotate to reel in the traction rope, and simultaneously pull the turntable so that the turntable drives the rotating shaft to rotate, and simultaneously drives the gear to rotate, and drives the half gear to rotate, and synchronously drives the soldering head to rotate at the same angle through the connecting seat.

At this time, the block on the upper side of the auxiliary plate will block the guide port. When the welding liquid is injected into the soldering head through the liquid supply pipe, the welding liquid at the lower side of the liquid storage box drops faster, and the auxiliary plate drives the block downward. At this time, the guide port is not blocked, and the welding liquid can be replenished to the lower side of the liquid storage box through the guide port. At this time, the amount of welding liquid stored at the lower side of the liquid storage box can be relatively stable to a certain extent, reducing the phenomenon of empty spraying when the soldering head sprays liquid due to the reduction of the liquid storage amount.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The auxiliary plate 29 includes a table top 1, the upper surface of the table top 1 is fixedly connected with a support column 4, and the side end of the support column 4 is fixedly connected with a liquid storage box 7, and the support column 4 is fixedly connected with an electric slide 5, and the electric slide 5 is provided with a soldering head 9, and a liquid supply pipe 10 is connected between the soldering head 9 and the liquid storage box 7;

[0048] The partition 32 is fixedly connected to the inside of the liquid storage box 7, and a plurality of groups of guide ports 33 are provided on the partition 32 at equal distances, and the liquid storage box 7 and the partition 32 can be used as auxiliary mechanisms for adjusting the amount of solder liquid stored;

[0049] The lower side of the table top 1 is fixedly connected with an electric slide rail 2, and the electric slide rail 2 is electrically connected with a sliding seat 3, and the upper side of the sliding seat 3 is fixedly connected with a placing table 6, and the placing table 6 is nested and connected to the outer side of the upper surface of the table top 1;

[0050] The auxiliary mechanism includes an auxiliary plate 29, a buffer rod 37 is fixedly connected to the inside of the auxiliary plate 29, and the auxiliary plate 29 is nested on the outside of the buffer rod 37, and a buffer spring 36 is fixedly connected between the edge of the auxiliary plate 29 and the buffer groove 35; a stopper 34 is fixedly connected to the upper side of the auxiliary plate 29, and the stopper 34 is nested in the inside of the guide port 33, the lengths of the auxiliary plate 29 and the partition 32 are both less than the maximum length of the liquid storage box 7, and the auxiliary plate 29 forms an elastic structure with the buffer groove 35 through the buffer spring 36.
