Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production, in particular to a cleaning fixture for circuit board patch processing. Background Art

[0002] After the circuit board is completed with patch welding, it needs to be cleaned to remove impurities such as flux and pollutants remaining on the circuit board during the welding process, preventing polar residues formed by such substances from covering the surface of the solder joints and causing short-circuit phenomena during the later power-on use of the circuit board. Since the sizes of circuit boards with different size specifications vary greatly, and the existing circuit board fixtures are generally fixed non-adjustable structures, resulting in the fixture not being adjustable according to the size of the circuit board during use. Therefore, it is necessary to specially mold and process corresponding fixtures according to different specifications of circuit boards. Therefore, it is necessary to provide a new cleaning fixture for circuit board patch processing to solve the above technical problems. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a cleaning fixture for circuit board patch processing.

[0004] A cleaning fixture for circuit board patch processing includes an installation frame and several partition frames in an I-shaped structure. The bottom surfaces at both ends in the length direction of the installation frame are provided with several corresponding positioning grooves. Both ends of the bottom plate of the partition frame are provided with convex pieces for inserting and matching the positioning grooves, and the convex pieces and the corresponding positioning grooves are connected by preset screw holes and bolts.

[0005] Rolling components are provided on both sides of the frame edges in the length direction of the installation frame and the webs of the partition frames. The rolling components include upper and lower installation bars. The installation bar located below is fixedly connected to the bottom plates of the corresponding installation frame and partition frame. The installation bar located above is rotationally assembled with an adjusting rod through a bearing at the midpoint of its own length, and the adjusting rod is screwed with preset screw holes in the corresponding frame edge of the installation frame and the top plate of the partition frame.

[0006] Workers can control the position of the partition frame in the positioning groove according to the size specification of the circuit board, and then divide the interior of the installation frame into a containing space suitable for different specifications of circuit boards. The convex pieces at both ends of the partition frame can be inserted into the corresponding positioning grooves, and then the positioning frame and the convex pieces can be fixed with bolts.

[0007] Preferably, guide rods are provided on both sides of the top of the installation bar located above. The top ends of the guide rods penetrate through the corresponding frame edges of the installation frame and the top plates of the partition frames and are exposed to the outside, and scale bars are provided on the rod bodies of the guide rods.

[0008] Preferably, a plurality of uniformly distributed spherical shells are provided on the opposite surfaces of the upper and lower mounting bars. A rolling ball is provided inside the spherical shell, and a part of the sphere of the rolling ball is exposed to the outside from the notch of the spherical shell.

[0009] After the installation of the partition frame is completed, the distance between the upper and lower mounting bars can be controlled according to the thickness specification of the circuit board: Rotate the adjusting rod relative to the mounting frame or the partition frame, so that the adjusting rod drives the corresponding mounting bar to move vertically until the distance between the rolling balls on the two mounting bars is equivalent to the thickness of the circuit board. When loading the circuit board on the present utility model later, first keep the circuit board horizontally placed and both ends enter between the corresponding two groups of mounting bars, and are carried by the rolling balls. In this way, after multiple circuit boards are sequentially moved in place, the upper and lower mounting bars can be adjusted to clamp the circuit board. If friction occurs during the movement of the circuit board, it is the rolling friction between its flat end face and the rolling ball. On the one hand, it reduces wear; on the other hand, the contact between the circuit board and the rolling ball is a point contact later, effectively reducing the covered area of the circuit board and improving the cleaning effect.

[0010] Preferably, one end in the width direction of the mounting frame is of an open structure, and insertion frames are fixedly provided at both ends of the open structure. A baffle is vertically inserted between the two insertion frames.

[0011] Preferably, several rotating rods are threadedly connected to the baffle. One end of the rotating rod is assembled with an extrusion plate through a bearing. Limiting rods are provided on both sides of the rotating rod, and the limiting rods are inserted into preset through holes on the baffle.

[0012] The insertion frames are provided for carrying the baffle. The baffle is used for blocking the open structure of the mounting frame on the one hand, and on the other hand, it can also block and limit the space filled with circuit boards currently through its own extrusion plate: After the circuit boards in the space between two adjacent partition frames or between the partition frame and the adjacent mounting frame are installed, the baffle can be inserted into the insertion frame, and then the rotating rod is rotated so that the extrusion plate moves towards the circuit board until it touches the circuit board, so that the circuit boards in the corresponding space can be limited.

[0013] After the cleaning is completed, the baffle and the insertion frame can be separated by reverse operation, and the staff can quickly take out the circuit board through the open structure of the mounting frame.

[0014] Compared with the related art, the cleaning fixture for circuit board chip processing provided by the present utility model has the following beneficial effects:

[0015] The present utility model divides the interior of the mounting frame into several spaces with different gaps by arranging a movable partition frame inside the mounting frame, so that different specifications of circuit boards can be clamped and fixed during use, and then the device can realize the clamping and fixing of different specifications of circuit boards, so the application range of the device can be improved.

[0016] By setting up the rolling components, during the process of placing or taking out the circuit board, the possible friction of the circuit board is converted into rolling point friction, and at the same time, the covering area caused by clamping the circuit board is small, improving the cleaning effect.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0023] Please refer to Figures 1 to 4 , a cleaning fixture for circuit board chip processing, includes a mounting frame 1 and several partition frames 2 in an I-shaped structure. The bottom surfaces at both ends in the length direction of the mounting frame 1 are provided with several corresponding positioning grooves 11. Both ends of the bottom plate of the partition frame 2 are provided with tabs 21 for inserting into the positioning grooves 11, and the tabs 21 and the corresponding positioning grooves 11 are connected by bolts through preset screw holes;

[0024] One end in the width direction of the mounting frame 1 is in an open structure, and insertion frames 5 are fixedly provided at both ends of the open structure. A retaining piece 4 is vertically inserted between the two insertion frames 5. Several rotating rods 6 are threadedly connected to the retaining piece 4. One end of the rotating rod 6 is assembled with a pressing plate 61 through a bearing. Limiting rods are provided on both sides of the rotating rod 6 and the limiting rods are inserted into preset through holes on the retaining piece 4.

[0025] Rolling components 3 are provided at both the lengthwise frame edges of the installation frame 1 and on both sides of the webs of the partition frames 2. The rolling components 3 include upper and lower mounting bars 31. The lower mounting bar 31 is fixedly connected to the bottom plates of the corresponding installation frame 1 and partition frame 2. The upper mounting bar 31 is rotatably assembled with an adjusting rod 312 through a bearing at the midpoint of its own length. The adjusting rod 312 is screwed into preset screw holes in the frame edges of the corresponding installation frame 1 and the top plates of the partition frames 2. On both sides of the top of the upper mounting bar 31, guide rods 311 are provided. The top ends of the guide rods 311 penetrate through the frame edges of the corresponding installation frame 1 and the top plates of the partition frames 2 and are exposed to the outside. A scale bar is provided on the rod bodies of the guide rods 311. On the opposite surfaces of the upper and lower mounting bars 31, a number of uniformly distributed spherical shells 32 are provided. A rolling ball 321 is provided inside the spherical shell 32, and a part of the sphere of the rolling ball 321 is exposed to the outside from the notch of the spherical shell 32.

[0026] The working principle of the present utility model is as follows:

[0027] First, according to the specifications of the circuit boards to be cleaned, the staff takes out the corresponding number of partition frames 2 and installs them at different positions in the installation frame 1, thereby dividing the interior of the installation frame 1 into storage spaces suitable for circuit boards of different specifications.

[0028] Then, the circuit boards are horizontally placed in several independent spaces separated by the partition frames 2, and both ends of the circuit boards are supported by the rolling balls 321 of the two lower mounting bars in this space. Then, by pushing the circuit boards, the circuit boards can be slid into the interior of the installation frame 1. By repeating this step, the circuit boards to be cleaned can be installed in the installation frame 1 in sequence. Then, the adjusting rod 312 is rotated. The adjusting rod 312 drives the upper mounting bar 31 to move downward, and the distance between the two mounting bars 31 is controlled by the scale lines on the outer wall of the guide rod 311. Finally, the two mounting bars 31 clamp the circuit boards.

[0029] Then, the baffle 4 is inserted into the insertion frame 5, and the rotating rod 6 is rotated so that the pressing plate 61 moves towards the circuit board until it touches the circuit board, thus completing the limiting of the circuit board in the corresponding space. After the cleaning is completed, the reverse operation can be performed to separate the baffle 4 and the insertion frame 5, and the staff can quickly take out the circuit boards through the open structure of the installation frame 1.
