Description

Technical Field

[0001] The invention relates to the field of computer maintenance, in particular to computer equipment maintenance chip auxiliary disassembly equipment. Background Art

[0002] There are multiple electronic components inside the computer, which usually consist of PCB boards, chips, capacitors, etc. When the chip is damaged and needs to be repaired, it is necessary to remove the chip from the surface of the PCB board and replace it with a new PCB board. The chip and the PCB board are connected by soldering. When disassembling, it is necessary to heat it first to melt the solder at the connection before the chip can be removed. The general disassembly method is to manually use a hot air gun to blow air. However, during the blowing process, the hot air diffuses outward, resulting in a decrease in the heating effect and low disassembly efficiency.

[0003] The utility model patent with application number CN201621433376.2 discloses a chip removal tool, whose structure includes a bracket, a hand wheel and a removal device. The chip removal tool can not only disassemble chips of different sizes, but also ensure that the chip is evenly stressed and not easily damaged when it is used to pull out the chip multiple times.

[0004] However, during the actual disassembly and use process, a hot air gun is needed to melt the tin at the connection between the chip and the motherboard first. The heat generated by the hot air gun during heating will diffuse outward, and the outward-diffused hot air flow will heat the components on the outside, causing other chips on the outside to be easily damaged by heat.

[0039] Specifically, the chip is clamped by the cooperation of four positioning clamps 44, and the positioning clamps 44 perform soft clamping under the elastic support of the buffer spring 56 during clamping, which has a buffering function, can prevent the clamping force from being too large, and improve the protection effect of the chip.

[0040] In this embodiment, the power device 7 includes a telescopic push rod 71, a power motor 72, a power gear 73, a limit gear 74, a positioning slot 75, a positioning rod 76, a clamping gear ring 77 and an air supply gear ring 78.

The power motor 72 is installed below the telescopic push rod 71, the power gear 73 is installed on the output end of the power motor 72, the limit gear 74 is rotatably installed with the bottom of the power gear 73 through a bearing, the positioning slot 75 is opened at the top of the side seat 31, the positioning rod 76 is installed on the bottom of the limit gear 74, the bottom end of the positioning rod 76 is inserted into the positioning slot 75, the clamping gear ring 77 is installed on the outer wall of the transmission turntable 61, and the air supply gear ring 78 is installed on the outer wall of the ring seat 8.

[0041] Specifically, the power device 7 drives the device to perform the clamping work, and at the same time, the power device 7 drives the internal hot air flow to circulate and heat the chip.

[0042] In this embodiment, the guide clamping strip 54 is clamped inside the guide clamping seat 48 , and the sleeve 53 is sleeved on the outside of the outer support roller 47 .

[0043] Specifically, the guide card strip 54 is stuck in the guide card seat 48, and the guide card strip 54 can be pulled horizontally along the guide card seat 48, so that the position of the dividing strip 52 is limited by the guide card strip 54 to prevent the dividing strip 52 from falling downward. At the same time, the sleeve 53 is sleeved on the outside of the outer support roller 47 to fix the end of the dividing strip 52, and then the side of the dividing strip 52 away from the sleeve 53 is surrounded by the outside of the four positioning card plates 44, and supported by the cooperation of the middle support roller 46 and the outer support roller 47 on the outside of the positioning card plate 44 to prevent the dividing strip 52 from directly contacting the positioning card plate 44 , reducing friction. During installation, the left end of the dividing tape 52 is connected to the outer wall of the winding roller 50, and the dividing tape 52 is wound around the outside of the winding roller 50, and the right end of the dividing tape 52 is first passed through the gap between the middle support roller 46 on the surface of the leftmost positioning card plate 44 and the outer support roller 47 on the rear side, and then the dividing tape 52 is passed around the outside of the remaining three positioning card plates 44, and then the sleeve 53 is put on the outside of the leftmost positioning card plate 44 and located on the surface of the outer support roller 47 on the front side, and then the guide strip 54 is clamped inside the guide card seat 48, so that the dividing tape 52 can slide along the outside of the positioning card plate 44.

[0044] In this embodiment, the positioning rod 76 is installed at a position away from the center of the circle at the bottom of the limiting gear 74, and the positioning rod 76 is an elliptical cylinder. The positioning slot 75 is adapted to the positioning rod 76, and a thin rubber protective gasket is installed at the bottom end of the positioning card plate 44.

[0045] Specifically, after the positioning rod 76 is inserted into the positioning slot 75, it cannot rotate. The positioning rod 76 restricts the limit gear 74 so that the limit gear 74 can only move in the up and down directions and cannot rotate. As a result, when the limit gear 74 moves to the outside of the clamping gear ring 77 and engages with the clamping gear ring 77, the clamping gear ring 77 is fixed, thereby fixing the transmission turntable 61 and maintaining the clamping state.

[0046] In this embodiment, the power gear 73 is meshed with the air supply gear ring 78, and the limiting gear 74 is meshed with the clamping gear ring 77. The upper and lower sides of the tooth head of the outer wall of the power gear 73 are both opened as a boss, and the upper side of the tooth head of the outer wall of the limiting gear 74 is opened as a boss.

The telescopic push rod 71 is an electric push rod, and the power motor 72 drives the power gear 73 to move vertically, thereby controlling whether the power gear 73 is engaged with the air supply gear ring 78 or the clamping gear ring 77. When the power gear 73 is engaged with the air supply gear ring 78, it drives the ring seat 8 to rotate to allow the internal gas to circulate. When the power gear 73 is engaged with the clamping gear ring 77, it drives the transmission turntable 61 to rotate, and drives the limit slot 62 to rotate through the transmission turntable 61, thereby adjusting the grasping device 4 to perform clamping work, and the thickness of the power gear 73 is less than the spacing between the air supply gear ring 78 and the clamping gear ring 77, so that the power gear 73 can only be engaged with one of the air supply gear ring 78 or the clamping gear ring 77 at the same time.

[0048] In this embodiment, a rubber fur strip is disposed at the bottom of the separation strip 52 .

[0049] Specifically, the bottom of the dividing strip 52 will not directly contact the surface of the PCB board, and the bottom end of the rubber bristle strip at the bottom of the dividing strip 52 will contact the PCB board. When the rubber bristle strip encounters other components on the surface of the PCB board, the rubber bristles will automatically bend so that they can pass smoothly. The gap between the bottom of the dividing strip 52 and the PCB board is sealed by the rubber bristle strip to prevent hot air from diffusing outward through the gap during heating.

[0050] In this embodiment, a guide hood 13 is installed on the top of the heating nozzle 12, a lower exhaust fan blade 15 is installed on the inner wall of the heating nozzle 12 and located near the top, and an upper exhaust fan blade 14 is installed on the outer wall of the heating nozzle 12 and located near the top, and the outer end of the upper exhaust fan blade 14 is installed on the inner wall of the ring seat 8.

[0051] Specifically, the interior of the top cover 9 and the ring seat 8 are divided into two cavities by the cooperation of the heating nozzle 12 and the guide cover 13. The interior of the inner heating nozzle 12 is a cavity for downward blowing and heating, and the outer cavity of the heating nozzle 12 is a cavity for upward reflux of heated gas.

[0052] In this embodiment, the upper exhaust fan blades 14 and the lower exhaust fan blades 15 have opposite spiral directions.

[0053] Specifically, the rotation of the upper exhaust fan blades 14 and the lower exhaust fan blades 15 causes the air inside the deflector scoop 13 to flow downward, and the air outside the deflector scoop 13 to flow upward, forming a circular flow.

[0054] In this embodiment, a heating wire is installed on the inner wall of the top cover 9 through a bracket, and a temperature sensor is arranged on the inner wall of the heating nozzle 12 and located near the bottom.

[0055] Specifically, the gas inside the top cover 9 is heated by the heating wire, and the heated gas enters the guide cover 13 and the heating nozzle 12 as it circulates and flows downward. The temperature is detected by the temperature sensor inside the heating nozzle 12 to prevent the PCB board from being damaged due to excessive temperature during heating.

[0056] The working principle and use process of the present invention are as follows: the device is connected and installed with a control arm with horizontal and vertical movement by connecting the flange seat 2, the infrared positioning head 10 is turned on, and the rays of the infrared positioning head 10 pass through the transparent glass plate 11, the deflector bucket 13 and the heating nozzle 12 and then irradiate the surface of the PCB board, and then the device is controlled to translate so that the irradiation point moves to the position just above the chip, and then the device is controlled to descend so that the bottom end of the positioning card plate 44 moves above the PCB surface, and then the telescopic push rod 71 is controlled to drive the power motor 72 to move downward, and the power motor 72 drives the power gear 73 and the limit gear 74 to move downward, and the limit gear 74 moves downward to release the restriction and fixation with the clamping gear ring 77, and the power gear 73 moves to the outside of the clamping gear ring 77 The side meshes with the clamping gear ring 77, and the power motor 72 drives the power gear 73 to rotate, the power gear 73 drives the clamping gear ring 77 to rotate, the clamping gear ring 77 drives the transmission turntable 61 to rotate, the transmission turntable 61 drives the limit card slot 62 to rotate, the limit card slot 62 pushes the limit push rod 55 to slide inward along the positioning slide groove 41, the moving slide seat 42 drives the buffer spring 56, the buffer seat 43 and the positioning card plate 44 to move inward, the positioning card plate 44 drives the bottom drag sheet 49 to move inward and insert it to the outside of the bottom of the chip. After the four positioning card plates 44 and the bottom drag sheet 49 are all stuck on the outside of the chip, the power motor 72 is turned off, and the dividing belt 52 is supported by the four positioning card plates 44 to seal the outside of the chip above, and the telescopic push rod 71 is controlled to drive the power motor 72 moves upward, the power motor 72 drives the power gear 73 to move upward and mesh with the air supply tooth ring 78, the power gear 73 drives the limit gear 74 to move upward and mesh with the clamping tooth ring 77 to fix the clamping tooth ring 77, and control the heating wire to heat, the power motor 72 starts to drive the power gear 73 to rotate, the power gear 73 drives the air supply tooth ring 78 to rotate, the air supply tooth ring 78 drives the ring seat 8 to rotate, the ring seat 8 drives the upper exhaust fan blades 14 to rotate, the upper exhaust fan blades 14 rotate to push the heated gas outside the heating nozzle 12 upward, the airflow flows along the top of the top cover 9 and then gathers in the middle, the upper exhaust fan blades 14 drive the heating nozzle 12 to rotate, the heating nozzle 12 drives the lower exhaust fan blades 15 to rotate, the lower exhaust fan blades 15 rotate to drive the heating wire to enter The hot air flow inside the hot nozzle 12 flows downward to heat the chip, and the hot air flow contacts the chip and diffuses outward. After the air flow diffuses outward, it flows upward under the obstruction of the dividing belt 52, and the air flow passes through the reflux opening 32 and the limit card slot 62 and flows to the internal cavity of the upper ring seat 8 and the top cover 9, and is heated again, thereby realizing the circulation of the hot air flow. The circulating gas is heated by the heating wire, and the hot air flow heats the chip. The heating uniformity is improved by the air flow heating method.

The chip is clamped and removed upward by the cooperation of the four positioning card plates 44 and the bottom drag sheet 49, thereby completing the chip disassembly work.
