Description

Technical Field

[0001] This utility model relates to the field of electroplating parts production technology, specifically to an electroplating etching cleaning device with a cleaning solution replacement structure. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics. Etching, on the other hand, uses a chemical solution to contact the workpiece, dissolving unwanted metals and leaving the desired pattern after electroplating. After processing, residual substances on the workpiece need to be removed with a cleaning solution. During the cleaning process, the workpiece needs to be immersed in the cleaning solution. After a period of use, the cleaning solution needs to be replaced. However, in the current technology, the cleaning solution needs to be drained before new cleaning solution is injected into the cleaning tank, which reduces work efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the deficiencies and shortcomings of the existing technology by providing a reasonably designed and easy-to-use electroplating and etching cleaning device with a cleaning solution replacement structure, which can effectively solve the defects of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a base plate and a mounting frame, wherein the mounting frame is provided on the upper side of the base plate, the mounting frame is arranged in an inverted "U" shape, the vertical plates on both sides of the mounting frame are fixedly connected to the base plate, and the outer walls on both sides of the mounting frame are flush with the two sides of the base plate; it also includes:

[0005] The cleaning tank is located on the lower side inside the mounting frame. The two sides of the cleaning tank are fixedly connected to the vertical plates of the mounting frame. The cleaning tank is equipped with a partition frame inside. The partition frame is arranged in a "+" shape. The cleaning tank is divided into four cavities by the partition frame. The support plate of the partition frame is sealed and abuts against the inner ring wall of the cleaning tank. The two side walls of the partition frame are sealed and abut against the two inner walls of the cleaning tank.

[0006] Two rotating plates are respectively embedded and fixed in the two side walls of the partition frame. The other side wall of the rotating plate is in contact with the two inner walls of the washing tub. A rotating shaft is fixed on the side wall of the rotating plate away from the partition frame. The rotating shaft passes through the side wall of the washing tub through a sealed bearing and is then screwed into the vertical plates on both sides of the mounting frame through a bearing.

[0007] The drive motor is fixed on the top wall of the base plate, and the output shaft of the drive motor is inserted into the vertical plate on one side of the mounting bracket. The output shaft of the drive motor is connected to one of the rotating shafts through a synchronous pulley transmission assembly.

[0008] The mounting plate is suspended on the upper side of the cleaning tub. Openings are provided on both the upper and lower sides of the outer ring wall of the cleaning tub. Several suction cups are fixed in a matrix on the lower surface of the mounting plate. The suction cups are suspended on the upper side of the openings. The mounting plate is connected to the horizontal plate of the mounting frame through a lifting mechanism.

[0009] Two water pipes are connected and inserted through the outer ring wall of the cleaning tank on the left and right sides respectively. The two water pipes are connected to the external cleaning liquid source and the external liquid storage tank respectively.

[0010] The above technical solution involves injecting a corresponding amount of cleaning fluid into the upper cavity, then connecting the water pipe on one side of the cavity to the external cleaning fluid, thereby injecting the cleaning fluid into the cavity. The stiff workpiece is adsorbed onto the suction cup. The lifting mechanism is activated, which moves the mounting plate downwards. The mounting plate, through the suction cup, moves the workpiece downwards, passing through the opening on the upper side of the cleaning tank and inserting it into the cleaning tank for cleaning. After cleaning is completed, the drive motor is activated. The drive motor, through the synchronous wheel transmission assembly, drives the rotating shaft connected to it to rotate the rod. This rotating shaft drives the rotating plate, the partition frame, and the rotating plate on the other side to rotate. The partition frame moves the cleaning fluid on the upper side to the other side inside the cleaning tank. At this time, the clean cleaning fluid is pushed to the upper side inside the cleaning tank, thus facilitating cleaning.

[0011] As a further improvement of this utility model, the lifting mechanism includes:

[0012] The connecting plates are two in number and are symmetrically fixed to the top wall of the mounting plate. The front and rear sides of the connecting plates are screwed with rotating rods through shafts.

[0013] The telescopic link consists of two telescopic links, which are symmetrically arranged on the upper side of the mounting plate. The support rods on both sides of the lower end of the telescopic link are respectively screwed to the upper end of the corresponding rotating rod through shafts. The support rods on both sides of the upper end of the telescopic link are screwed to sliding blocks through shafts. The sliding blocks are slidably arranged in the sliding groove on the lower side of the horizontal plate of the mounting frame.

[0014] Two bidirectional lead screws are provided, which are symmetrically embedded on the left and right and screwed into the horizontal plate of the mounting frame through bearings. The two bidirectional lead screws are connected by a synchronous pulley transmission assembly, and the sliding block is screwed onto the corresponding bidirectional lead screw through a thread.

[0015] The lifting motor is embedded and fixed in the horizontal plate of the mounting frame, and the output shaft of the lifting motor is fixedly connected to one end of one of the bidirectional lead screws.

[0016] With the above technical solution, the lifting motor is started, which drives the connected bidirectional lead screw to rotate. The bidirectional lead screw drives another bidirectional lead screw to rotate through the synchronous wheel transmission assembly. The two bidirectional lead screws drive the sliding blocks on both sides of their respective sides to move. The sliding blocks drive the upper end of the telescopic connecting rod to move, thereby causing the lower end of the telescopic connecting rod to drive the rotating rod to rotate. During the rotation, the rotating rod drives the mounting plate to move up and down through the connecting plate.

[0017] As a further improvement of this utility model, a graphite pad is fixed on the outer wall of the support plate of the partition frame, and the graphite pad is arranged to abut against the inner wall of the washing tub.

[0018] The above technical solution can increase the sealing between the separator and the cleaning box.

[0019] As a further improvement of this utility model, a fixed plate is fixed on the upper surface of the base plate, and a movable block is slidably arranged on the upper side of the fixed plate. A reciprocating screw is screwed into the interior of the movable block through a thread. One end of the reciprocating screw is screwed into the fixed plate through a bearing. A rotary motor is fixed on the other end of the reciprocating screw. The rotary motor is embedded and fixed in one side wall of the mounting frame. A cleaning plate is suspended on the upper side of the fixed plate. The lower side of the cleaning plate is sleeved on the movable block. A rotary motor is embedded inside the movable block. The output shaft of the rotary motor is connected to a rotating rod through a worm gear pair. The rotating rod is screwed into the movable block through a bearing. After the two ends of the rotating rod pass through the movable block, they are fixedly connected to the cleaning plate. After the cleaning plate passes through the lower opening, it is located on the lower side inside the cleaning tank. The side wall of the cleaning plate is set to abut against the partition frame.

[0020] With the above technical solution, after the cleaning fluid is discharged, the rotary motor is started. The rotary motor drives the rotating rod to rotate through the worm gear pair. The rotating rod drives the cleaning plate to rotate, so that the cleaning plate is inserted into the cleaning tank. Then the rotary motor is started again, and the rotary motor drives the reciprocating screw to rotate. The reciprocating screw drives the moving block to move back and forth. The moving block drives the cleaning plate to move back and forth in the cleaning tank, thereby cleaning the inner wall of the partition rack.

[0021] As a further improvement of this utility model, several dust removal holes are equidistantly arranged on the lower side wall of the fixing plate, the interior of the bottom plate is a hollow structure, the inlet on the upper side wall of the bottom plate is located below the dust removal holes, and the front side of the bottom plate is an open structure.

[0022] With the above technical solution, during the cleaning process, impurities pass through the dust removal holes and enter the interior of the base plate. After a period of time, the base plate is cleaned.

[0023] As a further improvement of this utility model, a collection box is provided inside the base plate. The collection box passes through the opening on the front side wall of the base plate and is exposed on the front side of the base plate, which facilitates the collection of impurities.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: The electroplating and etching cleaning device with a cleaning fluid replacement structure described in this utility model divides the cleaning tank into several cavities, which can discharge the original cleaning fluid and fill it with new cleaning fluid at the same time during the workpiece cleaning process, thereby improving work efficiency.
