Description

TECHNICAL FIELD

[0001] The present specification relates to the technical field of circuit board packaging, and in particular to a blocking mechanism for a PCBA packaging device. BACKGROUND

[0002] There are many packaging methods for PCBA (Printed Circuit Board + Assembly), such as coating the surface of the circuit board with three-proof paint, potting, and low-pressure injection molding. Each of the above methods has its own advantages and disadvantages: direct spraying of three-proof paint, although simple, convenient and easy to implement, cannot truly protect the circuit board and cannot achieve waterproofing and shockproofing; potting is tedious, inefficient, costly and has poor reliability; low-pressure injection molding uses a low-pressure injection molding device to complete the packaging of the circuit board by using a dedicated mold and adjusting the corresponding injection pressure and time. This method has a high cost of mold design and production, and the characteristics of the glue itself have a large impact on packaging.

[0003] In the patent with application number CN2021 / 131465 and the name "PCBA board packaging method and packaging equipment thereof", the adopted scheme is suitable for reliable packaging of low-height PCBA (PCBA board), but the incoming PCBA often deviates, and if the angle of the PCBA is not adjusted correctly in time, it will increase the defect rate of the subsequent packaged products.

[0004] In the patent with application number CN202311160341.0 and the name "PCBA packaging device and PCBA deviation adjustment method", the adopted scheme can quickly and reliably adjust the angle of the PCBA before packaging to avoid PCBA deviation. However, the blocking mechanism is complex and needs to control the position of the blocking mechanism according to the position of the PCBA during transportation, and the blocking mechanism is arranged near the carrier frame and blocks the PCBA from below, which may interfere with the lifting assembly and the deviation correction mechanism, affecting the deviation correction of the PCBA and further affecting the packaging accuracy of the PCBA.

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0035] Please refer to Figures 1 to 3 The embodiment of the present application provides a blocking mechanism for a PCBA packaging device, which comprises a mounting frame 1, a mounting plate 2, a blocking piece 3, a first driving piece (not shown in the figure) and a second driving piece 4.

[0036] Among them, the mounting frame 1 is provided with a sliding rail 121 extending along a horizontal direction X. The mounting plate 2 is slidingly installed on the sliding rail 121. The first driving piece is connected with the mounting plate 2, and is used for driving the mounting plate 2 to move along the horizontal direction X. The blocking piece 3 is installed on the mounting plate 2. The blocking piece 3 has a blocking position for blocking the PCBA at the working station 9 and a avoiding position higher than the blocking position. The second driving piece 4 is connected with the blocking piece 3, and is used for driving the blocking piece 3 to move along the vertical direction Y to switch between the blocking position and the avoiding position.

[0037] The blocking mechanism for the PCBA packaging device provided by the embodiment can be integrally arranged above the PCBA conveying line through the mounting frame 1, so as to block the PCBA from above and avoid interference. The blocking mechanism has a simple structure, and the blocking piece 3 can be moved in the horizontal direction X through the slide rail 121 and the first driving piece, that is, the position of the blocking piece 3 in the horizontal direction X is adjustable, so that the PCBA of different lengths can be blocked. The blocking mechanism can drive the blocking piece 3 to move in the vertical direction Y through the blocking piece 3 and the second driving piece 4, so as to switch between the blocking position and the avoiding position, thereby quickly and effectively blocking the PCBA at the working station 9.

[0038] In the embodiment, as shown in Figure 1 The mounting frame 1 includes two vertically arranged support portions 11 and a horizontally arranged mounting portion 12, and the slide rail 121 is located on the upper surface and the lower surface of the mounting portion 12. The two support portions 11 can mount the blocking mechanism on the bearing frame 7 of the PCBA packaging device, as shown in Figure 3 The upper surface and the lower surface of the mounting portion 12 are each provided with the slide rail 121, so that the mounting plate 2 can be better connected, and the mounting plate 2 can move more stably in the horizontal direction X.

[0039] Specifically, the mounting portion 12 is provided with a support block 5 at each end in the horizontal direction X, and the support block 5 is connected to the vertical surface of the support portion 11 and the bottom surface of the mounting portion 12, respectively, so that the support portion 11 can stably support the mounting portion 12. The support block 5 can be connected to the mounting portion 12 and the support portion 11 through screws or other fasteners, so as to facilitate the installation and disassembly of the mounting frame 1.

[0040] As shown in Figure 2 The mounting plate 2 is provided with two slide blocks 21 on the side facing the slide rail 121, and the two slide blocks 21 are connected to the slide rail 121 on the upper surface and the lower surface of the mounting portion 12, respectively. The slide block 21 is connected to the vertical surface of the mounting plate 2 and the slide rail 121 on the mounting portion 12, respectively, so as to stably connect the mounting portion 12 and the mounting plate 2.

[0041] The mounting position of the first driving piece is not limited in the embodiment. Preferably, the second driving piece 4 is mounted on the mounting plate 2, so as to quickly drive the blocking piece 3. The second driving piece 4 and the blocking piece 3 are arranged on the back surface of the side of the mounting plate 2 provided with the slide block 21, so as to reasonably utilize the space.

[0042] In the embodiment, the mounting plate 2 is further provided with a connecting piece 6, and the second driving piece 4 and the mounting plate 2 are connected through the connecting piece 6.

[0043] Specifically, the number of the connecting pieces 6 is two, and the two connecting pieces 6 are spaced apart in the vertical direction Y, so as to stably fix the second driving piece 4 to the mounting plate 2.

[0044] More specifically, the second driving piece 4 extends in the vertical direction Y, and the second driving piece 4 has a fixed part 41 and a moving part 42, the fixed part 41 is connected with the connecting piece 6, and the moving part 42 is located below the fixed part 41, and the blocking piece 3 is connected with one end of the moving part 42 away from the fixed part 41. The second driving piece 4 can be a pneumatic cylinder. The two connecting pieces 6 are respectively located at both ends of the fixed part 41 in the vertical direction Y.

[0045] Preferably, in the vertical direction Y, the length of the mounting plate 2 can be slightly greater than the length of the fixed part 41 of the second driving piece 4, and the mounting part 12 is located at a position slightly below the middle of the fixed part 41 of the second driving piece 4, so that the mounting plate 2 can be better moved in the horizontal direction X.

[0046] It should be noted that the horizontal direction X in the present application is parallel to the conveying direction of the PCBA, and the position of the blocking piece 3 in the horizontal direction X is adjustable, which not only avoids interference (i.e. avoids interference with the glue spraying assembly) when spraying glue on the PCBA, but also can block PCBA of different lengths. By adjusting the position of the blocking piece 3 in the horizontal direction X, the center of the blocked PCBA is always located at the center of the working station 9, so as to facilitate subsequent angle adjustment and glue spraying of the PCBA. The length of the PCBA in the embodiment of the present application refers to the size of the PCBA in the horizontal direction X.

[0047] As shown in Figure 3 When the supporting part 11 of the mounting frame 1 is fixedly connected with the side of the bearing frame 7 away from the conveying assembly 8, the blocking piece 3 is located above the working station 9, and when the blocking piece 3 is in the blocking position, the PCBA conveyed by the conveying assembly 8 can be blocked, so that the PCBA is located in the working station 9, and by adjusting the position of the blocking piece 3 in the horizontal direction X, the center of the blocked PCBA is located at the center of the working station 9.
