DETAILED DESCRIPTION

[0036] 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.

[0037] See also Figure 1-9 The present invention provides a technical solution: a laptop shell processing and welding device, comprising a reaction pool 1 in which an electrolyte solution is arranged, a conductive part 3 of the present invention is installed inside and at the bottom of the reaction pool 1, and is used for cathodic protection of the laptop shell, a circulation part 4 of the present invention is installed at the bottom of the reaction pool 1, and is used for circulating the solution to separate hydrogen bubbles from the flow, a convection part 5 of the present invention is installed on the reaction pool 1, and the hydrogen bubbles are separated from the electrode surface through convection between the solution and the circulation part 4, and a clamping part 6 of the present invention is installed at the edge of the reaction pool 1, and is used for clamping the laptop shell and increasing the area of ​​cathodic protection and reducing the disturbance of the water surface by the hydrogen bubbles,

[0038] In the present invention, cathodic protection of the metal shell of the notebook is realized based on the principle of electrochemical corrosion. The conductive part 3 of the present invention includes an insulating chassis 31, which is installed at the bottom of the outer wall of the reaction tank 1. A copper bar 32 is embedded on the top of the insulating chassis 31. A guide column 33 is arranged on the copper bar 32. A spiral electrode 34 is fixedly connected to the guide column 33. The spiral shape can increase the contact area of ​​the hydrogen bubbles, slow down the climbing speed of the hydrogen bubbles, and thus reduce the disturbance of the water surface. A gasket 35 is fixedly connected to the spiral electrode 34. The gasket 35 is made of insulating material to avoid direct current from contacting the surface of the notebook metal shell. To prevent pollution and ensure the safety of personnel during loading, a power interface 36 is provided on the front side of the outer wall of the insulating chassis 31, and the power interface 36 is electrically connected to the copper bus 32. The insulating chassis 31 is a mouth-shaped structure. There are two copper busbars 32 and they are symmetrically distributed on the top of the insulating chassis 31. There are four guide pillars 33, four spiral electrodes 34 and four gaskets 35. Every two guide pillars 33 are respectively fixedly connected to the ends of the copper busbars 32 on the same side. Four mounting holes 2 are symmetrically opened at the bottom of the inner wall of the reaction pool 1. The four guide pillars 33 are respectively fixedly connected to the inner walls of the four mounting holes 2 and seal the mounting holes 2.

[0039] In this embodiment, in order to further reduce the concentration of hydrogen bubbles and water surface disturbance, the circulation part 4 of this case includes a frame 41, which is fixedly connected to the bottom of the outer wall of the reaction tank 1, and the frame 41 is located between the inner walls of the insulating case 31. A water pump 42 is installed on the inner wall of the frame 41, and its model adopts an irg type vertical circulation pump. The inlet of the water pump 42 is connected to a water suction pipe 43, and the outlet of the water pump 42 is connected to a water outlet pipe 44. The ends of the water suction pipe 43 and the water outlet pipe 44 are respectively fixedly connected to the two sides of the insulating case 31 and are connected.

[0040] In order to increase the turbulence of the solution and accelerate the dispersion and removal of hydrogen bubbles from the electrode, the convection part 5 of this case includes a bracket 51, which is fixedly connected to one side of the outer wall of the reaction tank 1. A rotating motor 52 is installed on the bracket 51, and the output shaft of the rotating motor 52 is fixedly connected to a rotating shaft 1 53. A rotating shaft 2 54 is rotatably connected to one side of the inner wall of the reaction tank 1, and a stirring paddle 55 is fixedly connected to the end of the rotating shaft 2 54. Pulleys 56 are fixedly sleeved on the rotating shafts 1 53 and 2 54, and a transmission belt 57 is connected between the two pulleys 56.

[0041] It is worth noting that in order to adapt to notebook shells of different sizes for stable loading, the clamping part 6 of this case includes a rod sleeve 61, which is fixedly connected to the edge of one side of the pool mouth of the reaction pool 1. An electric push rod 62 is installed on the inner wall of the rod sleeve 61. The inner rod end of the electric push rod 62 is fixedly connected to an insulating plate 63, and the bottom of the insulating plate 63 is fixedly connected to a grille 64. The grille 64 can increase the bubble climbing area and reduce the effect of concentrated floating of bubbles. There are two clamping parts 6, and the other clamping part 6 is symmetrically installed on the edge of the other side of the pool mouth of the reaction pool 1.

[0042] It is worth noting that the four corners of the bottom of the outer wall of the reaction pool 1 are fixedly connected with legs 7, and the bottoms of the four legs 7 are fixedly connected with a bottom plate 8. A displacement mechanism 9 is arranged on the top rear side of the bottom plate 8. The displacement mechanism 9 includes two parallel linear motors and one transverse linear motor. The two parallel linear motors are symmetrically installed on the top rear side of the bottom plate 8, and the transverse linear motor is installed on the mover ends of the two parallel linear motors. A laser welding gun 10 is installed on the mover end of the transverse linear motor. A laser displacement sensor 11 is aligned and installed on one side of the emission end of the laser welding gun 10. The model is optoNCDT14xx / 2300. The laser displacement sensor 11 is electrically connected to the rotating motor 52. The feedback signal is formed by calculating the refraction angle of the laser displacement sensor 11 to drive the rotating motor 52 to work. The rotation speed of the rotating motor 52 is proportional to the size of the refraction angle. A notebook shell 12 is arranged in the reaction pool 1. The notebook shell 12 is placed on four gaskets 35, and the notebook shell 12 is clamped between two grids 64.

[0043] The working principle is that the inner rod of the electric push rod 62 is extended and retracted to drive the insulating plate 63 to move, thereby adjusting the distance between the grids 64 on both sides, thereby achieving the purpose of adapting to notebook shells 12 of different sizes. The notebook shell 12 is immersed in the electrolyte solution and clamped and fixed by the grids 64 on both sides. After being energized through the power interface 36, direct current is caused to be conducted to the guide column 33 through the copper bus 32, and then the current is passed through the spiral electrode 34 through the guide column 33, so that the electrolyte solution is energized to apply current to the metal notebook shell 12, making it a cathode, thereby inhibiting and slowing down the corrosion of the metal.

[0044] Based on the principle of electrochemical corrosion, hydrogen bubbles are generated in the electrolyte solution. The spiral structure of the spiral electrode 34 and the pores between the grids 64 can provide more escape channels for the bubbles, increase the contact area between the bubbles and the electrode surface, and reduce the adhesion strength of the bubbles on the electrode surface, thereby promoting the detachment of the bubbles, avoiding the problem of a large number of bubbles overflowing and causing strong shaking of the water surface, thereby ensuring the stability of the water surface.

[0045] On the other hand, the water pump 42 is used to cause the electrolyte solution to circulate along the water suction pipe 43 and the water outlet pipe 44, so that the electrolyte solution always flows in the right direction in the reaction tank 1, so that the hydrogen bubbles are separated from the electrode surface and dispersed in the solution. A ray is vertically projected into the electrolyte solution through the laser displacement sensor 11. Based on the vertical projection, when the laser with an incident angle of 0 degrees enters the water from the air, according to the law of refraction, the incident angle is 0 and the refraction angle is 0, which means that when the vertically projected laser enters the water, its propagation direction does not change and it still propagates in the vertical direction. However, in this case, considering the circulation of the water surface and the continuous generation of bubbles, it will affect the laser beam to a certain extent. The refraction angle causes the laser to deviate to the right to a certain extent. At this time, the laser displacement sensor 11 can accurately calculate the offset and synchronously drive the rotating motor 52 according to the feedback signal, so that the rotating shaft 1 53 and the rotating shaft 2 54 rotate synchronously based on the pulley 56 and the transmission belt 57, so that the stirring paddle 55 stirs the electrolyte solution, thereby causing the stirred electrolyte solution to form a convection effect with the electrolyte solution circulating to the right, and taking the hydrogen bubbles away from the electrode area in time to prevent the hydrogen bubbles from gathering on the electrode surface. The refraction angle of the laser displacement sensor 11 is proportional to the rotation speed of the stirring paddle 55, thereby further improving the electrode reaction efficiency, the uneven electrode surface, and the effect of interfering with the current distribution.

[0046] In the improved electrolyte solution, the water surface is stable and the hydrogen bubbles are dispersed and flow in an orderly manner, which can further compensate for the refraction accuracy in laser welding and reduce welding errors. The displacement mechanism 9 is used to drive the laser welding gun 10 to adjust the processing position based on the X and Y axes, and the Z-axis movement of the laser welding gun 10 itself is used to adjust the welding position, so that the gun head of the laser welding gun 10 is immersed in the electrolyte solution to perform welding processing on the notebook shell 12. The accelerated oxidation reaction of the metal caused by the high temperature of welding is protected by the cathodic protection to form an anti-oxidation layer, which greatly reduces the oxidation area of ​​the welding point and prevents the oxidation from further spreading, thereby improving the welding safety, the accuracy of the welding point and the welding quality.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
