Description

Technical Field

[0001] This specification relates to the technical field of circuit board packaging, and particularly to a deviation rectifying mechanism for a PCBA packaging device. Background Art

[0002] There are many packaging methods for PCBA (Printed Circuit Board + Assembly), such as applying three-proof 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: directly spraying three-proof paint, although simple, convenient, and easy to implement, cannot truly protect the circuit board, cannot achieve waterproof and shockproof functions, and over time, the packaging may fail; potting is cumbersome, inefficient, costly, and has poor reliability; low-pressure injection molding uses low-pressure injection molding equipment to complete the packaging of the circuit board through a special mold and by adjusting the corresponding injection pressure and time. This method has relatively high mold design and manufacturing costs, and the characteristics of the glue itself have a greater impact on the packaging.

[0003] In the patent with the application number CN2021 / 131465 and the name "Packaging Method and Packaging Equipment for PCBA Boards", the adopted solution is suitable for the reliable packaging of low-height PCBA (PCBA boards). However, the PCBA as the incoming material often deviates. If the angle of the PCBA is not adjusted correctly in time, it will lead to an increase in the defect rate of the subsequent packaged products. In the prior art, the rotation table is used to adjust the angle of the PCBA, with low accuracy, long adjustment time, and low efficiency. Utility Model Content

Beneficial effects

[0019] The deviation rectifying mechanism for the PCBA packaging device provided by this embodiment can drive two relatively arranged clamping plates to approach or move away from each other along the first direction through the setting of the first driving member, so as to clamp or loosen the PCBA; by setting the second driving member to drive the clamping plate to rotate, the angle of the PCBA can be rotated and adjusted when the PCBA is clamped by the clamping plate, avoiding the deviation of the PCBA.

The terms used herein in the specification of this utility model are only for the purpose of describing specific implementations and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] Please refer to Figures 1 to 4 An alignment mechanism for a PCBA packaging device provided by an embodiment of this application includes a mounting frame 1, a clamping plate 2, a first driving member 3 and a second driving member 4.

[0035] Among them, the mounting frame 1 is fixedly arranged. The two clamping plates 2 are arranged oppositely and are located above the mounting frame 1. The opposite sides of the two clamping plates 2 are used to clamp the PCBA. The first driving member 3 is connected to the clamping plate 2 and is used to drive the two clamping plates 2 to approach or separate from each other along the first direction X. The second driving member 4 is connected to the clamping plate 2 and is used to drive the clamping plate 2 to rotate. The first direction X is parallel to the rotation plane of the clamping plate 2. The first driving member 3 and the second driving member 4 are arranged below the clamping plate 2 and are located inside the mounting frame 1. It should be noted that the rotation plane in this application is parallel to the horizontal plane.

[0036] The alignment mechanism for the PCBA packaging device provided by this embodiment, by setting the first driving member 3 to drive the two oppositely arranged clamping plates 2 to approach or separate from each other along the first direction X, can clamp or loosen the PCBA; by setting the second driving member 4 to drive the clamping plate 2 to rotate, the angle of the PCBA can be rotated and adjusted when the PCBA is clamped by the clamping plate 2, avoiding the offset of the PCBA. This alignment mechanism can clamp the PCBA for rotational alignment to adjust the angle of the PCBA, so that the angle of the PCBA is accurate during packaging, thereby facilitating the spraying and packaging of the PCBA by the spraying component accurately. Using the rotational alignment method to adjust the angle of the PCBA can quickly and reliably adjust the angle of the PCBA before packaging. Compared with the method of using a rotating workbench to adjust the angle of the PCBA, the adjustment method of this alignment mechanism has high precision, short adjustment time and high efficiency, and when performing spraying and packaging, the clamping plate 2 clamping the PCBA can ensure that the angle of the PCBA is fixed without offset, thereby ensuring high packaging accuracy.

[0037] In addition, the mounting frame 1 is fixedly arranged and remains stationary. The mounting frame 1 can be fixedly installed on a workbench or other work surface to provide an installation position for the correction mechanism. The two clamping plates 2 are located above the mounting frame 1, and the first driving member 3 and the second driving member 4 are arranged below the clamping plates 2 and located in the mounting frame 1, so that the correction mechanism has a reasonable layout and effectively utilizes space.

[0038] In this embodiment, a fixing block 5 is fixedly provided at the bottom of the clamping plate 2. When the clamping plate 2 moves or rotates along the first direction X, the fixing block 5 does not move or rotate with the clamping plate 2. The deviation correction mechanism also includes a cam 6. The cam 6 is in continuous contact with a side of the fixing block 5 that is away from the other clamping plate 2 along the first direction X. The cam 6 rotates around a fixed axis to make the two clamping plates 2 approach or move away from each other. The fixed axis extends along a second direction Y, which is perpendicular to the first direction X and parallel to the rotation plane of the clamping plate 2. The first driving member 3 is connected to the cam 6 and is used to drive the cam 6 to rotate around the fixed axis.

[0039] Taking the distance from the fixed axis to the side of the cam 6 as the radius of the side, the cam 6 has a first side with the smallest radius and a second side with the largest radius. The fixed axis of the cam 6 remains stationary relative to the mounting frame 1, and a second elastic member (not shown) extending along the first direction X is provided between the clamping plate 2 and the mounting frame 1. When the first side of the cam 6 contacts the fixed block 5, the second elastic member is in a natural state, and the distance between the two clamping plates 2 is the largest; when the cam 6 rotates to the second side and contacts the fixed block 5, the second elastic member is compressed, and the two clamping plates 2 move inward to clamp the PCBA.

[0040] Preferably, the fixing block 5 is cylindrical and extends along the second direction Y. The cam 6 is in continuous contact with the circular side surface of the fixing block 5. The fixing block 5 can rotate around the rotation axis extending along the second direction Y, so that the fixing block 5 and the cam 6 maintain synchronous rotation in opposite directions, so that the cam 6 rotates more labor-saving and smoothly.

[0041] like Figure 2 As shown, a photoelectric sensing sheet 7 is fixed on the cam 6, and the photoelectric sensing sheet 7 can rotate around a fixed axis together with the cam 6. A photoelectric sensor 8 is provided on the mounting frame 1, and the photoelectric sensing sheet 7 can cooperate with the photoelectric sensor 8 to sense the position of the clamping plate 2 in the first direction X.

[0042] Specifically, Figure 3As shown, the photoelectric sensor 8 is provided with a first groove 81, and the photoelectric sensing sheet 7 can extend into the first groove 81 to cooperate with the photoelectric sensor 8 for sensing. The photoelectric sensor 8 is electrically connected to the first driving member 3. If the cam 6 is in the position where the first side contacts the fixed block 5, at this time, the photoelectric sensing sheet 7 is located outside the first groove 81 of the photoelectric sensor 8. When the first driving member 3 drives the cam 6 to rotate so that the second side contacts the fixed block 5, the two clamping plates 2 approach each other and can clamp the PCBA. If the cam 6 is in the position where the second side contacts the fixed block 5, at this time, the photoelectric sensing sheet 7 is located inside the first groove 81 of the photoelectric sensor 8. When the first driving member 3 drives the cam 6 to rotate so that the first side contacts the fixed block 5, the two clamping plates 2 move away from each other and can loosen the PCBA.

[0043] In this embodiment, a rotating table 9 is further provided in the mounting bracket 1, and the fixed block 5 is arranged below the rotating table 9. The rotation axis of the rotating table 9 extends in the vertical direction. The clamping plates 2 are fixedly installed on the upper surface of the rotating table 9. The rotating table 9 is connected to the second driving member 4, and the second driving member 4 is located on one side of the rotating table 9 in the second direction Y to make reasonable use of space. The second driving member 4 is used to drive the rotating table 9 to rotate, thereby driving the clamping plates 2 to rotate.

[0044] In one embodiment, the number of the second driving members 4 is one, which is connected to one of the clamping plates 2 and is used to drive one of the clamping plates 2 to rotate. The other clamping plate 2 is connected with a first elastic member (not shown in the figure). When the two clamping plates 2 clamp the PCBA inward and the second driving member 4 drives one of the clamping plates 2 to rotate, the other clamping plate 2 can rotate along with it. This embodiment only needs one second driving member 4 to drive the two clamping plates 2 to rotate simultaneously, and the structure is simple. The first elastic member has an elastic component along the first direction X and an elastic component along the second direction Y, so as to ensure that the other clamping plate 2 can rotate with the clamping plate 2 connected to the second driving member 4.

[0045] In another embodiment, the number of the second driving members 4 is two, which are respectively connected to the two clamping plates 2 and are used to drive the two clamping plates 2 to rotate simultaneously. The two second driving members 4 move synchronously, so as to realize the simultaneous rotation of the two clamping plates 2, and the rectification efficiency can be improved.

[0046] Preferably, the connection line of the rotation centers of the two clamping plates 2 extends along the first direction X, and when the two clamping plates 2 clamp the PCBA, the connection line of the rotation centers of the two clamping plates 2 passes through the center of the PCBA, so as to ensure that when the PCBA is rotationally rectified, the PCBA can rotate around its own center, which is convenient for quickly adjusting the PCBA to the correct position, thereby further improving the rectification efficiency.

[0047] As Figure 4As shown in the figure, on the opposite sides of the two clamping plates 2, there are inclined surfaces 10 for guiding. The distance between the two inclined surfaces 10 gradually increases from bottom to top, so that the PCBA can move upward along the inclined surfaces 10. Above the inclined surfaces 10 of the clamping plates 2, there are blocking parts 11. As the two clamping plates 2 continuously approach each other, the side of the PCBA first contacts the inclined surfaces 10 and then can move upward along the inclined surfaces 10 and is finally blocked by the blocking parts 11. At this time, the two clamping plates 2 are relatively stationary, realizing the clamping and fixing of the PCBA.

[0048] Preferably, there is a second groove 12 between the blocking part 11 and the inclined surface 10, and the thickness of the second groove 12 can be equal to the thickness of the PCBA. The inclined surface 10 is used for guiding, and the side of the PCBA finally contacts the second groove 12, which can ensure that the clamping plate 2 clamps and fixes the PCBA. The thickness of the clamping plate 2 is greater than the thickness of the PCBA to ensure a better offset adjustment effect.

[0049] In this embodiment, the rectifying mechanism further includes a camera (not shown in the figure) fixedly arranged on the mounting frame 1. After the clamping plate 2 clamps the PCBA, the camera can take a picture of the PCBA to obtain the offset angle of the PCBA, and the second driving member 4 can drive the clamping plate 2 to rotate according to the offset angle. Specifically, there are several positioning points on the PCBA. The camera takes a picture of the PCBA, so that the actual positions of the positioning points can be obtained. When spraying and encapsulating the PCBA, the PCBA needs to be located at a specific position. At this time, the position where the positioning points on the PCBA are located can be defined as the encapsulation position. By comparing the actual position with the encapsulation position, the offset angle of the PCBA can be obtained, so that the second driving member 4 drives the clamping plate 2 to rotate according to the offset angle, realizing the rectification of the PCBA, and the positioning points on the PCBA rotate from the actual position to the encapsulation position. The number of positioning points is preferably 2 or 3, which saves the rectification time while ensuring the rectification accuracy.

[0050] Compared with the method of obtaining the picture of the entire PCBA to adjust the position of the PCBA, in this embodiment, the offset angle is determined through the positioning points, which can avoid the error caused by the distortion during the transmission of the PCBA picture and avoid the time waste caused by a large amount of calculation.

[0051] In this embodiment, the rectifying mechanism further includes a controller (not shown in the figure) electrically connected to the first driving member 3, the second driving member 4 and the camera, which is used to control the start and stop of the first driving member 3, the second driving member 4 and the camera and receive the images taken by the camera. The first driving member 3 and the second driving member 4 in this embodiment can both be motors, or the types of driving members can be set appropriately according to needs.

[0052] In a specific application scenario, the controller controls the first driving member 3 to start, drives the cam 6 to rotate, makes the two clamping plates 2 approach each other, and after clamping the PCBA, the first driving member 3 shuts down. Then, the controller controls the camera to take a picture of the PCBA to obtain the offset angle of the PCBA. The controller controls the second driving member 4 to start, drives the clamping plate 2 to rotate by the offset angle according to the offset angle, and then the second driving member 4 shuts down. Then, the glue spraying assembly performs the spraying and encapsulation task. After the spraying is completed, the controller controls the first driving member 3 to start, drives the cam 6 to rotate to make the two clamping plates 2 move away from each other, and releases the PCBA from the clamping plates 2.
