Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, and in particular to a PCB board cleaning machine. Background Technology

[0002] A PCB, or printed circuit board, is a component that provides electrical connections for electronic components. It uses an insulating board as its base material, cut to a specific size, and has at least one conductive pattern and holes. It replaces the traditional chassis for mounting electronic components and enables interconnection between them. During the manufacturing process, contaminants such as flux and solder can remain on the surface of the PCB, necessitating cleaning. Ultrasonic cleaning equipment is now commonly used for this purpose.

[0003] Current PCB board cleaning machines have certain shortcomings in use. The efficiency of cleaning a single PCB board is low, so multiple PCB boards are put into the cleaning machine together for cleaning. However, when multiple PCB boards are put into the cleaning tank together, the PCB boards will come into contact and pile up. After contact with water, the PCB boards are also prone to sticking together, which makes it impossible to effectively clean the contact surfaces of the PCB boards. As a result, the cleaning effect of the PCB boards is poor and the cleaning efficiency of the cleaning machine is low. Therefore, improvements are now being made to the PCB board cleaning machine. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing cleaning machines cause PCB board contact accumulation during PCB board cleaning, resulting in ineffective cleaning of the PCB board and low cleaning efficiency. Therefore, a PCB board cleaning machine is proposed.

[0005] To achieve the above objectives, this utility model employs the following technology: a PCB board cleaning machine, comprising an ultrasonic cleaner and a cleaning tank disposed at the upper part of the ultrasonic cleaner, and further comprising:

[0006] The placement mechanism is attached to the inner wall of the cleaning tank. The placement mechanism includes a fixed frame that is attached to the inner wall of the cleaning tank. Several clamping parts and support blocks are fixedly installed on the fixed frame. The clamping parts are located above the support blocks. Several PCB boards are distributed in a rectangular array inside the cleaning tank through the clamping parts and support blocks.

[0007] The mounting mechanism is fixedly connected to the upper side of the fixed frame, and the placement mechanism is fixed inside the cleaning tank through the mounting mechanism.

[0008] As a further description of the above technical solution: the fixing frame includes a pair of horizontally parallel horizontal plates and a pair of vertically parallel vertical plates, the pair of horizontal plates and the pair of vertical plates forming a rectangular frame.

[0009] As a further description of the above technical solution: the clamping part includes a mounting plate fixed on the fixing frame. Both ends of the mounting plate are provided with screw holes. A pair of clamping plates are fixedly installed on the mounting plate. Each of the opposite surfaces of the pair of clamping plates is provided with a slot, and the slot is provided with an anti-slip rubber strip.

[0010] As a further description of the above technical solution: the spacing between the pair of clamps is greater than the thickness of the PCB board, the number of anti-slip strips is several, the anti-slip strips are cylindrical, and the outer side of the anti-slip strips protrudes from the outer surface of the clamps.

[0011] As a further description of the above technical solution: the support block has a U-shaped block structure, and the support block and the clamping part are located on the same vertical line.

[0012] As a further description of the above technical solution: the installation mechanism includes a hanging plate suspended from the top of the cleaning pool, one end of the hanging plate having a threaded rod through it, one end of the threaded rod being fixedly connected to a handle, and the other end of the threaded rod being fixedly connected to a pressure plate.

[0013] As a further description of the above technical solution: the hanging plate is hook-shaped, the threaded rod passes through one end of the hanging plate and is threadedly connected to the hanging plate, and the pressure plate is a circular plate structure.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] The mounting mechanism suspends and fixes the PCB board in the cleaning tank of the cleaning machine. During the PCB board cleaning process, the PCB board is inserted into the clamping part, so that the PCB board can be distributed in an array in the cleaning tank, which will not cause the PCB board to contact or pile up. This ensures that each PCB board can be thoroughly and effectively cleaned, improves the cleaning effect of the PCB board, and makes the cleaning machine more efficient. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-2 This embodiment provides a PCB board cleaning machine, including an ultrasonic cleaner 1 and a cleaning tank 2 disposed at the upper part of the ultrasonic cleaner 1. The cleaning tank 2 is equipped with a placement mechanism 4 through a mounting mechanism 4. The placement mechanism 4 is used to fix the PCB boards to be cleaned evenly and at intervals in the cleaning tank 2, so as to avoid the PCB boards in the cleaning tank 2 from contacting and piling up, thereby ensuring that each PCB board can be thoroughly and effectively cleaned.

[0025] Reference Figures 3-4 The placement mechanism 3 includes a fixing frame 31 that fits against the inner wall of the cleaning tank 2. Several clamping parts 32 and support blocks 33 are fixedly installed on the fixing frame 31. The clamping parts 32 are located above the support blocks 33. Several PCB boards are distributed in a rectangular array inside the cleaning tank 2 through the clamping parts 32 and support blocks 33. The fixing frame 31 fits against the inner wall of the cleaning tank 2. The clamping parts 32 and support blocks 33 realize the spaced distribution of several PCB boards, thereby avoiding contact and accumulation of PCB boards that need to be cleaned in the cleaning tank 2, and ensuring that each PCB board can be thoroughly and effectively cleaned.

[0026] The fixing frame 31 includes a pair of horizontally parallel horizontal plates and a pair of vertically parallel vertical plates. The pair of horizontal plates and the pair of vertical plates form a rectangular frame. The rectangular frame structure of the fixing frame 31 is used for the stable installation of the clamping parts 32 and the support blocks 33, so that several clamping parts 32 and support blocks 33 can be evenly arranged on the fixing frame 31, thereby realizing the fixing of the PCB board to be cleaned.

[0027] The clamping part 32 includes a mounting plate 321 fixed on the fixing frame 31. Both ends of the mounting plate 321 are provided with screw holes 322. A pair of clamping plates 323 are fixedly installed on the mounting plate 321. Each of the opposite surfaces of the pair of clamping plates 323 is provided with a slot 324, and the slot 324 is provided with an anti-slip strip 325. When fixing the PCB board, the PCB board is inserted from top to bottom between the two clamping plates 323 until the bottom of the PCB board abuts against the support block 33. After the bolts are screwed into the screw holes 322 of the mounting plate 321, the clamping plates 323 are fixed on the fixing frame 31. The anti-slip strip 325 on the slot 324 of the clamping plate 323 can prevent the inserted PCB board from slipping and falling during cleaning after the PCB board is fixed by the clamping part 32.

[0028] In this design, the spacing between a pair of clamping plates 323 is greater than the thickness of the PCB board. There are several anti-slip strips 325, which are cylindrical in shape and protrude from the outer surface of the clamping plates 323. The spacing between the clamping plates 323, which is greater than the thickness of the PCB board, ensures that the PCB board can be inserted between the clamping plates 323, thereby ensuring that the clamping plates 323 can clamp and fix the PCB board. The anti-slip strips 325 protruding from the outer surface of the clamping plates 323 can directly contact the PCB board, thereby achieving anti-slip and preventing the PCB board from detaching from the clamping plates 323.

[0029] Reference Figure 5 The installation mechanism 4 includes a hanging plate 41 suspended on the top of the cleaning tank 2. One end of the hanging plate 41 has a threaded rod 42 through it. One end of the threaded rod 42 is fixedly connected to a handle 43, and the other end of the threaded rod 42 is fixedly connected to a pressure plate 44. The hanging plate 41 is suspended at the edge of the ultrasonic cleaner 1 and the cleaning tank 2. The threaded rod 42 drives the pressure plate 44 to move, thereby clamping and fixing the hanging plate 41 on the cleaning tank 2, thus fixing the placement mechanism 3 in the cleaning tank 2.

[0030] The hanging plate 41 is hook-shaped, and the threaded rod 42 passes through one end of the hanging plate 41 and is threadedly connected to the hanging plate 41. The pressure plate 44 is a circular plate structure. The hook-shaped hanging plate 41 can be installed on the ultrasonic cleaner 1 and the cleaning tank 2. When the threaded rod 42 is rotated by the handle 43, it can move on the hanging plate 41, so that the pressure plate 44 abuts against the outer side of the ultrasonic cleaner 1, thereby fixing the hanging plate 41 and the placement mechanism 3.

[0031] Working principle: When using the PCB board cleaning machine of this application, the ultrasonic cleaner 1 is placed and fixed, and the hanging plate 41 is suspended at the edge of the ultrasonic cleaner 1 and the cleaning tank 2. Then, the threaded rod 42 is turned by the handle 43, so that the pressure plate 44 on the threaded rod 42 abuts against the outer surface of the ultrasonic cleaner 1, thereby fixing the hanging plate 41 on the cleaning tank 2 of the ultrasonic cleaner 1. The lower end of the hanging plate 41 is connected to the fixing frame 31. The clamping part 32 and the support block 33 are installed through the fixing frame 31. The PCB boards to be cleaned are inserted between the clamping plates 32 and 33 in sequence until the lower end of the PCB board abuts against the support block 33. The PCB boards to be cleaned are arranged in an array in the cleaning tank 2 by the clamping part 32 and the support block 33 on the fixing frame 31, so as to avoid the PCB boards from contacting and piling up. Then, cleaning water is poured into the cleaning tank 2, and the PCB boards are cleaned by the ultrasonic cleaner 1.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
