DETAILED DESCRIPTION

[0019] 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.

[0020] Reference Figures 1 to 5 As shown, in order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electroplating passivation processing device, comprising a passivation box 1, a liquid injection pipe 11, a liquid outlet pipe 12, a mounting assembly, a lifting assembly 3 and a swing assembly 4, the liquid injection pipe 11 and the liquid outlet pipe 12 are respectively connected to the passivation box 1; There are two groups of mounting components, both of which are mounted on the passivation box 1 through a lifting component 3. The lifting component 3 is used to synchronously drive the two mounting components to move up and down, and the lifting component 3 can respectively drive the two mounting components to move up to the same height and down to different heights; The mounting assembly includes a mounting frame 21, a placement frame 22 and an air guide plate. Both ends of the mounting frame 21 are respectively connected to the lifting assembly 3, the placement frame 22 is rotatably connected to the mounting frame 21, and the swing assembly 4 is installed on the mounting frame 21 to drive the placement frame 22 to swing. Two groups of air guide plates are provided and are respectively provided on both sides of the placement frame 22. A storage cavity 231 is provided in the air guide plate. An air inlet 232 and an air outlet 233 are provided on the air guide plate and are respectively connected to the storage cavity 231. A one-way valve 234 is provided between the storage cavity 231 and the air inlet 232 and the air outlet 233. A pressure relief assembly 5 is disposed in the storage cavity 231 , and pressure relief rods 221 are disposed on both sides of the placement frame 22 . The pressure relief rods 221 are arranged in linkage with the pressure relief assembly 5 .

[0021] According to the design of the present invention, the two groups of installation components are raised to the same height by the lifting component 3, and then the electroplated parts that need to be passivated are placed in the placement frame 22 according to the needs, and then the two groups of installation components are synchronously moved down by the lifting component 3, and the two installation components are respectively at different heights and the electroplated parts are fully in contact with the passivation liquid. At this time, the swing component 4 is started to drive the placement frame 22 to perform a constant speed or variable speed swinging motion, and the swinging direction is the opposite direction of the two placement frames 22. During the swinging process of the placement frame 22, the passivation liquid will fluctuate, thereby improving the contact effectiveness between the passivation liquid and the electroplated parts and improving the passivation effect.

[0022] Furthermore, during the swinging process of the placement frame 22, the pressure relief rod 221 can be continuously linked with the pressure relief assembly 5, thereby realizing lateral airflow, improving the circulation of the passivation liquid, and improving the passivation effect.

[0023] The present invention is further configured as follows: the lifting assembly 3 includes a lifting motor 31, a transmission gear set 32, a screw rod 33 and a guide rod 34, and two sets of screw rods 33 and guide rods 34 are provided, and each set of screw rods 33 and guide rods 34 is respectively connected to two sides of one of its mounting frames 21; The transmission gear set 32 ​​is connected to two sets of screw rods 33 and the lifting motor 31 respectively.

[0024] The design of this structure enables the four sets of screw rods 33 to rotate synchronously through the transmission gear set 32 ​​when the lifting motor 31 is started, so that the two mounting frames 21 can be lifted and lowered synchronously along the guide rod 34 .

[0025] The present invention is further configured as follows: the transmission gear set 32 ​​includes a first transmission gear 321, a second transmission gear 322, a first linkage gear 323, a second linkage gear 324 and a transmission chain, and the first transmission gear 321 and the second transmission gear 322 are each provided with two groups, the two first transmission gears 321 are respectively connected to one group of screw rods 33, and the two second transmission gears 322 are respectively connected to the other group of screw rods 33; The two first transmission gears 321 are connected via a transmission chain; The two second transmission gears 322 are connected via a transmission chain; The first linkage gear 323 is mounted on a first transmission gear 321, and the second linkage gear 324 is mounted on a second transmission gear 322. The first linkage gear 323 and the second linkage gear 324 are connected through a transmission chain. The diameter length of the first linkage gear 323 is greater than the diameter length of the second linkage gear 324 .

[0026] like Figure 4 The figure shows the position of the transmission chain.

[0027] When the lifting motor 31 is started, it can drive a first transmission gear 321 to rotate. Under the connection of the transmission chain, another first transmission gear 321 is rotated. At this time, the lead screw 33 connected to the first transmission gear 321 rotates, thereby lifting and lowering.

[0028] Furthermore, since the first linkage gear 323 is installed on the first transmission gear 321, when the first transmission gear 321 rotates, the first linkage gear 323 also rotates accordingly, and the first linkage gear 323 drives the second linkage gear 324 to rotate through the transmission chain. Since the second linkage gear 324 is installed on the second transmission gear 322, when the second linkage gear 324 rotates, the second transmission gear 322 also rotates accordingly, and then through the transmission chain, the other second transmission gear 322 rotates, thereby achieving the effect of synchronously moving the placement frame 22 up and down.

[0029] Since the diameter length of the first linkage gear 323 is greater than the diameter length of the second linkage gear 324, the number of rotations of the second linkage gear 324 is greater than the number of rotations of the first linkage gear 323. Therefore, during the startup of the lifting motor 31, the descending speed of one placement frame 22 is greater than the descending speed of the other placement frame 22. When the lifting motor 31 stops, the vertical position of one placement frame 22 is lower than the vertical position of the other placement frame 22.

[0030] The present invention is further configured as follows: the swing assembly 4 includes a swing motor 41, a swing arm 42 and a transmission rod 43, the swing arm 42 is connected to the output end of the swing motor 41, one end of the transmission rod 43 is connected to the swing arm 42, and the other end is connected to the placement frame 22; When the swing motor 41 is started, the transmission rod 43 pushes the placement frame 22 to perform a swing motion.

[0031] The design of the swing assembly 4 is such that when the swing motor 41 is started, the swing arm 42 is driven to perform a curved motion, thereby causing the placement frame 22 to perform a synchronous swing motion through the transmission rod 43. The swing assembly 4 adopts an existing structural design and will not be described in detail again.

[0032] The present invention is further configured as follows: the installation assembly includes a first installation assembly 2 and a second installation assembly 20 , and when the lifting assembly 3 drives the first installation assembly 2 and the second installation assembly 20 to move down to the lowest position, the first installation assembly 2 is located obliquely above the second installation assembly 20 .

[0033] The present invention is further configured as follows: a plurality of first liquid outlet grooves opening obliquely downward are provided on one side of the placement frame 22 of the first installation component 2 facing the second installation component 20; A plurality of second liquid outlet grooves opening obliquely upward are provided on the side of the placement frame 22 of the second installation component 20 facing the first installation component 2. The design of the first liquid outlet groove and the second liquid outlet groove can cause the passivation liquid to move toward the notch of the liquid outlet groove during the swinging process of the placement frame 22, so as to form a directional liquid flow inside the passivation liquid and improve the passivation effect.

[0034] The present invention is further configured as follows: an operating groove 235 having an arc-shaped structure is provided on the air guide plate, and the pressure relief rods 221 are respectively slidably connected in the operating groove 235 .

[0035] The present invention is further configured as follows: the pressure relief assembly 5 includes an exhaust airbag 51, an exhaust block 52 and an exhaust spring 53. The exhaust airbag 51 is arranged in the storage chamber 231. An operation port 6 is arranged between the storage chamber 231 and the operation slot 235. The exhaust block 52 is slidably connected to the operation port 6 through the exhaust spring 53. When the pressure relief rod 221 moves with the placement frame 22, when the pressure relief rod 221 abuts against the exhaust block 52, the exhaust block 52 is pushed to move inward, so that the exhaust block 52 squeezes the exhaust airbag 51, so that the gas in the exhaust airbag 51 is discharged from the outlet. When the pressure relief rod 221 continues to move with the placement frame 22, the pressure relief rod 221 separates from the exhaust block 52, and the exhaust block 52 is reset under the action of the exhaust spring 53. At this time, since the internal air pressure of the exhaust airbag 51 is less than the external air pressure, air enters the exhaust airbag 51 from the air inlet 232. The exhaust airbag 51 is preferably made of a material with a restoring spring.

[0036] The present invention is further configured as follows: the two groups of air guide plates are respectively a first air guide plate 23 and a second air guide plate 24, the first air guide plate 23 is arranged on a side of the placement frame 22 away from the swing assembly 4, and the second air guide plate is arranged on a side of the placement frame 22 close to the swing assembly 4; The air outlet on the first air guide plate 23 is arranged on a side facing the placement frame 22; The air outlet on the second air guide plate 24 is arranged at the upper end or the lower end.

[0037] The design of the air outlet enables a transverse convection airflow to be formed in the passivation box 1 when the pressure relief rod 221 triggers the pressure relief assembly 5 on the first air guide plate 23; When the pressure relief rod 221 triggers the pressure relief assembly 5 on the second air guide plate 24, a circulating airflow can be formed in the passivation box 1, so that different passivation effects can be formed according to the type of electroplated parts, passivation time, and passivation degree.

[0038] During the passivation process, the benefits of filling with gas are: 1. Preventing oxidation: Inert gas can isolate oxygen in the air, thereby preventing the electroplated parts from reacting with oxygen during the passivation process to generate oxides, which in turn affects the performance and appearance of the coating.

[0039] 2. Improve the coating environment: By increasing the gas pressure, the inert gas can improve the discharge conditions during coating, create a more stable and uniform coating environment, and is conducive to the formation of high-quality passivation film.

[0040] 3. Improve the quality of the coating: Under the protection of inert gas, the passivation process can proceed more smoothly, thereby reducing defects and impurities in the coating and improving the density and corrosion resistance of the coating.

[0041] 4. For example, in some electroplated parts, gases such as oxygen are introduced to participate in the reaction. The main function of these gases is to promote specific chemical reactions to generate a coating or passivation film with specific properties.

[0042] The present invention is further configured as follows: the operation port 6 , the exhaust block 52 and the exhaust spring 53 are each provided with two groups, and are respectively provided at two ends of the operation slot 235 .

[0043] The design of this structure can control whether the pressure relief rod 221 abuts against the corresponding exhaust block 52 by the rotation direction of the swing motor 41, so as to flexibly realize the gas mode.

[0044] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
