Description

Background technique

There are many packaging methods for PCBA (Printed Circuit Board+ Assembly), such as applying conformal paint on the surface of the circuit board, potting, and low-pressure injection molding. Each of the above methods has its own advantages and disadvantages: direct spraying of conformal protective paint, although the operation is simple, convenient and easy to implement, cannot truly protect the circuit board, cannot achieve waterproofing and shockproof, and the packaging may fail after a long time; Potting is a cumbersome operation with low efficiency, high cost and poor reliability; low-pressure injection molding uses low-pressure injection molding equipment to complete circuit board packaging through a dedicated mold and adjusts the corresponding injection pressure and time. This method has relatively high mold design and production costs. High, the characteristics of the glue itself have a greater impact on packaging.

In the patent application number PCT/CN2021/131465, titled "PCBA board packaging method and packaging equipment", the solution adopted is suitable for reliable packaging of low-height PCBA (PCBA board), but the PCBA as incoming material Offsets often occur. If the angle of the PCBA is not adjusted correctly in time, the defective rate of subsequent packaged products will increase. In the prior art, a rotating workbench is used to adjust the angle of the PCBA, but the accuracy is not high, the adjustment time is long, and the efficiency is low.

See Figure 1 to Figure 3. The embodiment of the present application provides a PCBA packaging device, which includes a glue spray component (not shown), a workbench 18 , a lifting component 4 and a correction mechanism 5 .

Among them, the glue spray component is used to spray glue liquid to the PCBA. The workbench 18 is located below the glue spray assembly. The lifting assembly 4 is disposed on the workbench 18 for carrying the PCBA 100 . The lifting component 4 has a correction position and a working position higher than the correction position. The correction mechanism 5 is arranged on the workbench 18, and the correction mechanism 5 can controllably clamp and release the PCBA 100 horizontally. When the lifting assembly 4 lifts the PCBA100 to the correction position, the correction mechanism 5 horizontally clamps the PCBA100 for correction, and releases the PCBA100 after correction. The lifting component 4 lifts the PCBA 100 to the working position when the PCBA 100 is released by the correction mechanism 5 .

The PCBA packaging device provided in this embodiment is provided with a lifting component 4 and a correction mechanism 5 on the workbench 18. When the lifting component 4 is located at the correction position, the correction mechanism 5 horizontally clamps the PCBA 100 for correction to adjust the angle of the PCBA 100, and After the deviation is corrected, the PCBA100 is released, so that the PCBA packaging device can quickly and reliably adjust the angle of the PCBA100 before packaging to avoid PCBA100 deviation. By arranging the glue spray assembly above the workbench 18, glue can be sprayed on the PCBA 100 when the lifting assembly 4 is further raised to the working position to complete the packaging. The working position is higher than the correction position, and the lifting component 4 lifts the PCBA 100 to the working position when the PCBA 100 is released by the correction mechanism 5, which can avoid obstruction caused by the correction mechanism 5 when the PCBA 100 is packaged.

In this embodiment, a transfer mechanism is provided on the workbench 18, and the transfer mechanism is used to transfer the PCBA 100 to the work station. The correction mechanism 5 and the lifting component 4 can correct and lift the PCBA 100 located at the work station, that is, the correction mechanism 5 and the lifting component 4 are both arranged at the work station.

Specifically, the transfer mechanism includes two conveyor belts 2 extending along the first direction X, and two carrier frames 1 opposite to each other. One of the carriers 1 is fixed on the workbench 18, and the other carrier 1 is movably disposed on the workbench 18 and can move along the second direction Y to change the distance from the fixed carrier 1, so that This PCBA packaging device is applied to PCBA100 of different widths. The lifting assembly 4 is arranged between the two bearing frames 1, and the two correction mechanisms 5 are respectively arranged on the two bearing frames 1.

Wherein, the first direction X and the second direction Y are vertical and parallel to the horizontal plane. The width of the PCBA 100 described in the embodiment of the present application refers to the size of the PCBA 100 along the second direction Y.

In this embodiment, a detection station is provided upstream of the work station, and the detection station is provided with a first photoelectric detection component. As shown in Figure 1, the work station is also provided with a blocking mechanism 3 for forming a block in the transfer direction of the PCBA 100 (ie, the first direction X). The blocking mechanism 3 is arranged on the carrying frame 1 . The blocking mechanism 3 has an escape position that allows the PCBA 100 to pass and a blocking position that blocks the PCBA 100 . When it is in the avoidance position, the blocking mechanism 3 does not block the transfer of the PCBA 100; when it is in the blocking position, the blocking mechanism 3 blocks the PCBA 100 at the work station. When the first photoelectric detection component detects the PCBA 100, the blocking mechanism 3 moves from the avoidance position to the blocking position. The lifting assembly 4 is located upstream of the blocking mechanism 3 . By setting the blocking mechanism 3, the PCBA 100 on the conveyor belt 2 can be blocked, and then the lifting assembly 4 can lift the PCBA 100.

In this embodiment, the deflection correction mechanism 5 includes two clamping members respectively provided on both sides of the lifting assembly 4 . The opposite sides of the two clamping parts are used to clamp and adjust the angle of PCBA100. When the lifting assembly 4 is in the correction position, the two clamping parts can clamp the PCBA100 on the lifting assembly 4 inward, and the distance between the two clamping parts is equal to the width of the PCBA100. When the lifting component 4 is in the working position, the distance between the two clamping parts is greater than the width of the PCBA100, which can avoid obstruction caused by the clamping parts when packaging the PCBA100. At this time, the glue spraying component can spray glue to the PCBA100.

Specifically, the lifting assembly 4 includes two lifting parts located inside the carrier frame 1 respectively. The lifting assembly 4 also has a standby position lower than the correction position. When the lifting component 4 is in the standby position, the top surface of the lifting component is lower than or flat to the top surface of the conveyor belt 2, and the distance between the two clamping components is greater than the width of the PCBA100. When the lifting component 4 is in the correction position, the top surface is higher than the top surface of the conveyor belt 2 .

Specifically, the speed at which the lifting component 4 switches from the standby position to the correction position is greater than the speed at which it switches from the correction position to the working position. This is because when the lifting component 4 switches from the correction position to the working position, the PCBA100 has completed the offset adjustment, and there are no constraints on the circumference of the PCBA100. If the speed of the lifting component 4 is too high at this time, it may cause the PCBA100 to shake during the rising process. This causes an angular shift. The speed of the lifting component 4 when switching from the correction position to the working position should be as small as possible to allow the PCBA 100 to rise smoothly and ensure that the PCBA 100 that has completed the offset adjustment will no longer produce angular offset.

In this embodiment, in order to enable the blocking mechanism 3 to switch between the avoidance position and the blocking position in a timely manner, the PCBA packaging device includes a first driving member 10 for driving the blocking mechanism 3 to switch between the blocking position and the avoiding position. The first photoelectric detection component includes a first photoelectric sensor 82 and a first photoelectric sensing sheet 81 . Among them, a rotatable first photoelectric sensor piece 81 is provided at the detection station, and a first photoelectric sensor 82 that cooperates with the first photoelectric sensor piece 81 and senses is fixed below the carrier 1 . When the PCBA 100 is not located above the first photoelectric sensor sheet 81 , the top of the first photoelectric sensor sheet 81 is higher than the upper surface of the conveyor belt 2 , and the bottom end does not cooperate with the first photoelectric sensor 82 ; when the PCBA 100 is located above the first photoelectric sensor sheet 81 , the top end of the first photoelectric sensor sheet 81 is flush with the upper surface of the conveyor belt 2 , and the bottom end cooperates with the first photoelectric sensor 82 .

The first photoelectric sensor 82 is electrically connected to the first driving member 10 . The blocking mechanism 3 is first in the avoidance position. When the PCBA 100 passes through the detection station, the top of the first photoelectric sensor sheet 81 is pressed down, so that the bottom end of the first photoelectric sensor sheet 81 cooperates with the first photoelectric sensor 82 to trigger The first photoelectric sensor 82 transmits the signal to the first driving component 10 , and the first driving component 10 drives the blocking mechanism 3 to switch from the avoidance position to the blocking position before the PCBA 100 reaches the blocking mechanism 3 .

Among them, the top surface of the first photoelectric sensor sheet 81 is preferably an arc surface, so as not to affect the transmission of the PCBA 100 at the detection station. The bottom end of the first photoelectric sensing sheet 81 is located on one side of the top end in the first direction X, that is, the bottom end and the top end of the first photoelectric sensing sheet 81 are staggered in the vertical direction. A point between the bottom end and the top end of the first photoelectric sensing sheet 81 is fixed to the carrying frame 1 . The first photoelectric sensor 82 is provided with a groove for sensing the bottom end of the first photoelectric induction piece 81. When the top end of the first photoelectric induction piece 81 is not pressed down, the bottom end of the first photoelectric induction piece 81 is located outside the groove, and the first The photoelectric sensor 82 fails to sense the first photoelectric sensor sheet 81; when the PCBA 100 is transmitted through the detection station, the top of the first photoelectric sensor sheet 81 is pressed down, and the bottom end of the first photoelectric sensor sheet 81 moves diagonally to the concave position. In the slot, the first photoelectric sensor 82 senses the first photoelectric sensing piece 81 and sends the signal to the first driving member 10 .

As shown in Figure 3, the PCBA packaging device also includes a second driving member 11 for driving the lifting assembly 4 to switch between the standby position, the correction position and the working position. In order to enable the second driving member 11 to drive the lifting assembly 4 to lift in time, a second photoelectric detection assembly is provided at the work station. The second photoelectric detection component includes a second photoelectric sensor 92 and a second photoelectric sensing sheet 91 .

Specifically, the work station is provided with a rotatable second photoelectric induction piece 91 , and a second photoelectric sensor 92 that cooperates with the second photoelectric induction piece 91 and senses is fixed below the carrier 1 . When the PCBA 100 is not located above the second photoelectric sensor sheet 91 , the top of the second photoelectric sensor sheet 91 is higher than the upper surface of the conveyor belt 2 , and the bottom end does not cooperate with the second photoelectric sensor 92 ; when the PCBA 100 is located above the second photoelectric sensor sheet 91 , the top end of the second photoelectric sensor sheet 91 is flush with the upper surface of the conveyor belt 2 , and the bottom end cooperates with the second photoelectric sensor 92 .

The second photoelectric sensor 92 is electrically connected to the second driving member 11 . The lifting assembly 4 is first in the standby position. When the PCBA 100 is blocked by the blocking mechanism 3 at the working station, the top of the second photoelectric sensor sheet 91 is pressed down, so that the bottom end of the second photoelectric sensor sheet 91 is in contact with the second photoelectric sensor 92 Cooperation is formed to trigger the second photoelectric sensor 92. The second photoelectric sensor 92 transmits the signal to the second driving component 11. After the PCBA 100 is blocked by the blocking mechanism 3, the second driving component 11 drives the lifting component 4 to switch from the standby position to the correction position. to lift PCBA100 to facilitate subsequent angle offset adjustment.

Specifically, the specific structures of the second photoelectric sensor sheet 91 and the second photoelectric sensor 92 may refer to the structures of the above-mentioned first photoelectric sensor sheet 81 and the first photoelectric sensor 82 respectively. Their structures are similar and will not be described again in this application.

Preferably, the second photoelectric sensor 92 and the first driving member 10 are electrically connected. After the second driving member 11 drives the lifting assembly 4 to leave the standby position, the top of the second photoelectric sensor sheet 91 returns to a position slightly higher than the top surface of the conveyor belt 2. At this time, the second photoelectric sensor 92 cannot sense the second photoelectric sensor sheet 91. , the second photoelectric sensor 92 transmits the signal to the first driving member 10, and the first driving member drives the blocking mechanism 3 to return to the avoidance position, so that after the lifting assembly 4 puts down the PCBA 100, the blocking mechanism 3 will not cause damage to the PCBA 100 on the conveyor belt 2 Movement creates obstruction.

As shown in Figure 1, the clamping member is provided with a top post 6 at one end away from the carrier 1 in the second direction Y. The PCBA packaging device also includes a cam 7 that is continuously in contact with the side of the top post 6. The cam 7 rotates around a fixed axis. Move the two clamping pieces closer or further away from each other. Taking the distance from the fixed axis to the side of the cam 7 as the radius at the side, the cam 7 has a first side with the smallest radius and a second side with the largest radius. The fixed axis of the cam 7 remains stationary relative to the carrier 1 , and an elastic member extending along the second direction Y is provided between the clamping member and the carrier 1 . When the first side of the cam 7 is in contact with the top post 6, the elastic member is in a natural state, and the distance between the two clamping parts is the largest; when the second side of the cam 7 is in contact with the top post 6, The elastic part is compressed, and the two clamping parts move inward to clamp the PCBA100.

In this embodiment, the cam 7 is connected to a third driving member 12 for driving the cam 7 to rotate, and the third driving member 12 is electrically connected to the second photoelectric sensor 92 . The cam 7 is first in the first side contact position with the top post 6. When the PCBA 100 is blocked at the working station by the blocking mechanism 3, the second photoelectric sensor 92 is triggered, and the second photoelectric sensor 92 transmits the signal to the third driver. Part 12, the third driving part 12 drives the cam 7 to rotate after the PCBA100 is blocked by the blocking mechanism 3, so that the second side is in contact with the top post 6, and the two clamping parts are close to clamp the PCBA100 and adjust the angle of the PCBA100. Avoid deflection.

In this embodiment, when the lifting component 4 is in the correction position, the top surface of the lifting component 4 is flush with the bottom surface of the clamping member. Preferably, the thickness of the clamping member is equal to the thickness of the PCBA 100, so that the top surface of the PCBA 100 lifted by the lifting assembly 4 is flush with the top surface of the clamping member. In other embodiments, the thickness of the clamping member may be slightly larger than the thickness of the PCBA 100 to ensure better offset adjustment effect.

Specifically, when the second driving member 11 drives the lifting assembly 4 to switch from the standby position to the correction position, the third driving member 12 drives the cam 7 to rotate. That is, when the PCBA 100 is blocked by the blocking mechanism 3 at the working station, the lifting assembly 4 and the clamping piece start moving at the same time. The speed of the rotation of the cam 7 is related to the speed of the lifting component 4 switching from the standby position to the correction position. When the lifting component 4 is in the correction position, the second side of the cam 7 is in contact with the top post 6 to ensure that the PCBA100 is effectively Make offset adjustments.

The rotation speed of the cam 7 needs to be reasonably controlled so that the time it takes for the cam 7 to rotate from the first position where the side is in contact with the top post 6 to the second position where the side is in contact with the top post 6 is greater than the time it takes for the lifting component 4 to move from the standby position. The time to switch to the correction position. When the lifting component 4 is in the correction position, after the PCBA100 is clamped by the clamping member and the angle adjustment is completed, the cam 7 continues to rotate and returns to the first position where the side is in contact with the top column 6. The compressed elastic member gradually resets during the process. , push the clamping parts to move outward, so that the distance between the two clamping parts is greater than the width of PCBA100. The lifting component 4 is switched from the correction position to the working position so that the top surface of the PCBA100 is higher than the top surface of the clamping piece, making it easier to package the PCBA100.

As shown in Figure 3, the carrier 1 is provided with a third photoelectric sensor 15 for sensing the position of the clamping member. The cam 7 is provided with a third photoelectric sensing piece 16 that matches the third photoelectric sensor 15 . The third photoelectric sensing piece 16 rotates around the fixed axis together with the cam 7 . The third photoelectric sensor 15 is provided with a groove, and the third photoelectric sensing piece 16 can extend into the groove to cooperate with the third photoelectric sensor 15 for sensing. The third photoelectric sensor 15 and the third driving member 12 are electrically connected. When the lifting component 4 is in the standby position, the first side of the cam 7 is in contact with the top post 6. At this time, the third photoelectric sensor piece 16 is located in the groove of the third photoelectric sensor 15; when the clamping piece needs to be clamped on the PCBA 100 , the third driving member 12 drives the cam 7 to rotate. During the rotation of the cam 7, when the second side is in contact with the top post 6, the clamping member clamps the PCBA 100 (at this time, the third photoelectric sensor sheet 16 leaves the third photoelectric sensor 15), and then the cam 7 continues to rotate until the first side is in contact with the top post 6, the third photoelectric sensor piece 16 returns to the groove of the third photoelectric sensor 15, and the third photoelectric sensor 15 sends a signal to The third driving member 12 drives the cam 7 to stop rotating.
