Description

Technical Field

[0001] The utility model relates to the technical field of disassembly of automobile electronic control units, in particular to a disassembly tool for an engine controller. Background Art

[0002] The structure of the vehicle controller is mainly composed of three parts: metal shell, PCBA in the middle, and metal back cover. The upper and lower metal shells are fixed by screws and silicone, and the PCBA and the upper and lower metal shells are fixed by silicone.

[0003] This disassembly tool is mainly used to disassemble PCBA and aluminum housing. PCBA and aluminum housing are mainly separated by tearing silicone. The stickiness of silicone will make disassembly more time-consuming and laborious. In addition, due to uneven or excessive force, it is easy to disassemble and deform the PCBA board and some parts on it, or cause defects when disassembling electronic components. Different models use different disassembly tools and cannot be shared. Utility Model Content

[0004] The utility model aims to provide an engine controller disassembly tool to solve the problem that the existing disassembly tool easily causes damage or deformation of the PCB board when disassembling the PCBA and the shell.

[0005] In order to solve the above problems, the utility model adopts the following technical means:

[0006] An engine controller disassembly tool, comprising:

[0007] A positioning frame is constructed with a positioning mechanism for fixing the controller in the X-axis and Z-axis directions, and the positioning mechanism is open in the Y-axis direction;

[0008] The worm gear screw lifting mechanism has a push plate at the lifting end, the push plate moves linearly along the Z axis, the push plate abuts against the connecting part of the controller, and is used to push the PCB board connected to the connecting part;

[0009] The positioning frame and the worm screw lifting mechanism are both installed on a base.

[0010] Preferably, the positioning frame includes a pair of return-shaped plates, the bottom surfaces of the return-shaped plates are detachably connected to the base, the top sides of the return-shaped plates are constructed with horizontal slide grooves, the horizontal ends of the slide grooves pass through the return-shaped plates, and the slide grooves on the two return-shaped plates are arranged oppositely and in parallel.

[0011] Furthermore, a horizontal aluminum pressure plate is provided on the top surface of the slide groove, and a pressing mechanism is provided on the top surface of the aluminum pressure plate. The pressing mechanism includes a pushing screw rotatably installed on the aluminum pressure plate, the pushing screw passes through the return plate upward, and the pushing screw is threadedly connected to the return plate.

[0012] Furthermore, the top surface of the base is constructed with a positioning groove, the bottom end of the circular plate is arranged in the positioning groove, the length of the positioning groove is the same as the length of the bottom end of the circular plate, the width of the positioning groove is greater than the thickness of the circular plate, and the circular plate and the top surface of the base are disassembled and fixed by bolts.

[0013] Furthermore, the top surface of the base is constructed with a clearance hole for the screw of the worm gear screw lifting mechanism to pass through, and the push plate includes a flat plate that is detachably connected to the lifting end of the worm gear screw lifting mechanism, and a vertical baffle is installed on the top surface of the flat plate, and the baffle abuts against the end of the connection part of the controller that is away from the controller.

[0014] Furthermore, the base includes four surrounding rectangular plates that are connected end to end in sequence, and the adjacent rectangular plates are detachably connected. A supporting plate is installed on the top surface of the rectangular plate for disassembling and installing the worm gear screw lifting mechanism and the positioning frame. The supporting plate is detachably connected to the rectangular plate, and the plate body of the rectangular plate is provided with a horizontally penetrating through groove.

[0015] During use, the utility model has the following beneficial effects:

[0016] The controller is limited in the X-axis and Z-axis directions by the positioning frame to avoid the deflection of the controller shell during the disassembly of the PCBA; and the open setting in the Y-axis direction is used to facilitate the installation of the metal parts of the controller into the positioning mechanism. The lifting action of the worm screw lifting mechanism is used to move the push plate back and forth along the Z-axis. When the push plate moves upward, the top of the push plate acts on the connection part of the controller. As the push plate continues to move upward, the PCBA board and the metal shell move relative to each other, so that the fixed silicone between the two is torn, and the PCBA and the metal shell are separated. And by using the setting of the worm screw lifting mechanism, the effect of pushing the PCBA can be adjusted by manually controlling the rotation speed of the turbine. The worm screw lifting mechanism can not only adjust the force on the PCB board more finely by rotating the turbine, but also stop rotating the turbine when it is found that the PCB and the metal shell are partially separated. At this time, the PCB board is in a partially slightly bent deformation state, and the PCB board's own elastic recovery force is used to break the fixed silicone. This effectively avoids the situation where excessive force causes plastic deformation or breakage of the PCB board. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Please refer to Figure 1 and Figure 2 As shown, an engine controller disassembly tool comprises:

[0027] The positioning frame 1 is constructed with a positioning mechanism for fixing the controller 2 in the X-axis and Z-axis directions, and the Y-axis direction of the positioning mechanism is open;

[0028] The worm gear screw lifting mechanism 3 is provided with a push plate 4 at the lifting end. The push plate 4 moves linearly along the Z axis. The push plate 4 abuts against the connecting portion 5 of the controller 2 to push the PCB board connected to the connecting portion 5.

[0029] The positioning frame 1 and the worm gear screw lifting mechanism 3 are both installed on a base 6 .

[0030] In this way, the positioning frame 1 is used to limit the controller 2 in the X-axis and Z-axis directions to avoid the deflection of the housing of the controller 2 during the disassembly of the PCB; and the open setting in the Y-axis direction is used to facilitate the installation of the metal parts of the controller 2 into the positioning mechanism. The lifting action of the worm screw lifting mechanism 3 is used to allow the push plate 4 to move back and forth along the Z-axis. When the push plate 4 moves upward, the top of the push plate 4 acts on the connecting portion 5 of the controller 2. As the push plate 4 continues to move upward, the PCB board and the metal shell move relative to each other, so that the fixed silicone between the two is pulled apart, and the PCB and the metal shell are separated. In addition, by using the setting of the worm screw lifting mechanism 3, the effect of pushing the PCB board can be adjusted by manually controlling the rotation speed of the turbine. The worm screw lifting mechanism 3 can not only adjust the force applied to the PCB board more finely by rotating the turbine, but also stop rotating the turbine when it is found that the PCB and the metal shell are partially separated. At this time, the PCB board is in a partially bent deformation state, and the fixed silicone is broken by using the elastic recovery force of the PCB board itself. This effectively avoids the situation where excessive force causes plastic deformation or breakage of the PCB board.

[0031] Furthermore, for the positioning frame 1, the positioning frame 1 includes a pair of return plates 11, the bottom surface of the return plate 11 is detachably connected to the base 6, and the top side of the return plate 11 is constructed with a horizontal slide groove 7 serving as the positioning mechanism, and the horizontal ends of the slide groove 7 pass through the return plate 11, and the slide grooves 7 on the two return plates 11 are arranged oppositely and in parallel.

[0032] In this way, by utilizing the hollow structure of the two-turn mold plates 11 , the weight of the positioning frame 1 can be greatly reduced, and the assembly of the positioning frame 1 is facilitated.

[0033] Furthermore, a horizontal aluminum pressure plate 8 is provided on the top surface of the slide groove 7, and a pressing mechanism is provided on the top surface of the aluminum pressure plate 8. The pressing mechanism includes a pushing screw 9 rotatably installed on the aluminum pressure plate 8, and the pushing screw 9 passes through the return plate 11 upward, and the pushing screw 9 is threadedly connected to the return plate 11.

[0034] The aluminum pressure plate 8 is then used to stably clamp the metal shell clamped in the slide groove 7 under the action of the pushing screw 9. The soft property of the aluminum plate allows the aluminum pressure plate 8 to fit well with the shell under the downward pressure of the pushing screw 9, thereby improving the clamping and limiting effect of the slide groove 7 on the shell.

[0035] Furthermore, the top surface of the base 6 is constructed with a positioning groove 10, the bottom end of the return plate 11 is arranged in the positioning groove 10, the length of the positioning groove 10 is the same as the length of the bottom end of the return plate 11, the width of the positioning groove 10 is greater than the thickness of the return plate 11, and the return plate 11 and the top surface of the base 6 are disassembled and fixed by bolts.

[0036] In this way, the distance between the two return plates 11 can be adjusted, that is, the return plates 11 can be moved in the positioning groove 10 along the width direction of the positioning groove 10, so that the positioning frame 1 can clamp controllers 2 of different widths. In addition, if the connection part 5 of some controllers 2 is not in the middle position and is partially offset, the position of the push plate 4 relative to the positioning frame 1 can be adjusted by adjusting the position of the return plates 11, so that the tooling can adapt to controllers 2 of different specifications.

[0037] The top surface of the base 6 is constructed with a clearance hole for the screw of the worm gear screw lifting mechanism to pass through, and the push plate includes a flat plate 41 that is detachably connected to the lifting end of the worm gear screw lifting mechanism, and a vertical baffle 42 is installed on the top surface of the flat plate 41, and the baffle 42 abuts against the end of the connecting part 5 of the controller facing away from the controller.

[0038] In this way, the flat plate 41 is used to push the bottom surface of the connecting portion 5, and the baffle 42 is used to limit the position of the controller in the Y-axis direction.

[0039] Furthermore, the base 6 includes four surrounding rectangular plates 61 that are connected end to end in sequence, and the adjacent rectangular plates 61 are detachably connected. A supporting plate 62 is installed on the top surface of the rectangular plate 61 for disassembling and installing the worm gear screw lifting mechanism 3 and the positioning frame 1. The supporting plate 62 is detachably connected to the rectangular plate 61, and the plate body of the rectangular plate 61 is provided with a horizontally penetrating through groove 12.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
