Description

Technical Field

[0001] The present invention relates to the technical field of circuit board packaging, and in particular to a blocking glue spraying mechanism for a PCBA packaging device. Background Art

[0002] There are many packaging methods for PCBA (Printed Circuit Board + Assembly), such as coating the surface of the circuit board with conformal coating, potting and low-pressure injection molding. Each of the above methods has its own advantages and disadvantages: direct spraying of conformal coating, although simple, convenient and easy to implement, cannot truly protect the circuit board, cannot achieve waterproof and shockproof, and the packaging may fail over time; potting is cumbersome, inefficient, costly and has poor reliability; low-pressure injection molding uses low-pressure injection molding equipment, special molds, and adjusts the corresponding injection pressure and time to complete the packaging of the circuit board. This method has high mold design and production costs, and the characteristics of the glue itself have a greater impact on the packaging.

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

[0004] In the patent with application number CN202311160341.0 and titled "PCBA Packaging Device and PCBA Offset Adjustment Method", the solution adopted can quickly and reliably adjust the angle of the PCBA before packaging to avoid PCBA offset. However, the blocking mechanism is complex in design, and the position of the blocking mechanism needs to be controlled according to the position of the PCBA during the conveying process. In addition, the blocking mechanism is arranged near the carrier frame, and the PCBA is blocked from below, which may interfere with the lifting component and the correction mechanism, affecting the correction of the PCBA, and further affecting the packaging accuracy of the PCBA.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] Please refer to Figures 1 to 3。The embodiments of the present application provide a blocking glue spraying mechanism for a PCBA encapsulation device, which includes a first mounting bracket 1, a glue spraying assembly 3, a blocking member 4, a first driving member (not shown in the figure), and a second driving member 5.

[0037] Among them, the glue spraying assembly 3 is mounted on the first mounting bracket 1 and is used to spray glue on the PCBA. The blocking member 4 is mounted on the first mounting bracket 1 and has a blocking position for blocking the PCBA at the working station and an avoidance position higher than the blocking position. The first driving member is connected to the first mounting bracket 1 and is used to drive the first mounting bracket 1 to move along the first direction X. The first direction X is parallel to the conveying direction of the PCBA. The second driving member 5 is connected to the blocking member 4 and is used to drive the blocking member 4 to move along the vertical direction Z to switch between the blocking position and the avoidance position. The second driving member 5 is mounted on the first mounting bracket 1.

[0038] The blocking glue spraying mechanism for the PCBA encapsulation device provided by this embodiment can be integrally arranged above the PCBA conveying line, so as to block the PCBA from above and avoid interference. The blocking glue spraying mechanism integrates the blocking member 4 and the glue spraying assembly 3 through the first mounting bracket 1, making the structure more compact. By setting the first driving member, the blocking member 4 can be moved in the first direction X, that is, the position of the blocking member 4 in the first direction X is adjustable, so that PCBAs of different lengths can be blocked. By adjusting the position of the blocking member 4 in the first direction X, the center of the blocked PCBA is always located at the center of the working station, which is convenient for subsequent angle adjustment and glue spraying of the PCBA. The length of the PCBA described in the embodiments of the present application refers to the dimension of the PCBA along the horizontal direction X.

[0039] The blocking glue spraying mechanism can drive the blocking member 4 to move along the vertical direction Z to switch between the blocking position and the avoidance position by setting the blocking member 4 and the second driving member 5, so as to quickly and effectively block the PCBA at the working station.

[0040] In this embodiment, when the blocking member 4 is in the blocking position, the lowest point of the blocking member 4 is lower than the bottom surface of the glue spraying assembly 3; when the blocking member 4 is in the avoidance position, the lowest point of the blocking member 4 is higher than the bottom surface of the glue spraying assembly 3, so that the blocking member 4 will not cause interference when the glue spraying assembly 3 sprays glue on the PCBA.

[0041] Such as Figure 1 and Figure 2As shown, a first slide rail 7 extending in the vertical direction Z is provided on the first mounting bracket 1. The glue spraying assembly 3 is slidably connected to the first slide rail 7 through a first slider 8, so that the glue spraying assembly 3 can move up and down relative to the first mounting bracket 1. The glue spraying blocking mechanism further includes a third driving member (not shown in the figure) connected to the glue spraying assembly 3, which is used to drive the glue spraying assembly 3 to move in the vertical direction Z for better glue spraying operation. In the embodiment of the present application, the installation position of the third driving member is not limited, and the fixed end of the third driving member can be fixed to the first mounting bracket 1.

[0042] In this embodiment, the glue spraying blocking mechanism further includes a second mounting bracket 2 and a fourth driving member. The first mounting bracket 1 is slidably mounted on the second mounting bracket 2. One end (fixed end) of the first driving member can be fixedly mounted on the second mounting bracket 2, and the other end (mobile end) of the first driving member is connected to the first mounting bracket 1. The fourth driving member is connected to the second mounting bracket 2 and is used to drive the second mounting bracket 2 to move in the second direction Y, so that the second mounting bracket 2 can drive the first mounting bracket 1 and the glue spraying assembly 3 mounted on the first mounting bracket 1 to move in the second direction Y, which is convenient for glue spraying on the PCBA. Wherein, the second direction Y is perpendicular to the first direction X and parallel to the horizontal plane. In the embodiment of the present application, the installation position of the fourth driving member is not limited.

[0043] As Figure 1 shown, a second slide rail 9 extending in the first direction X is provided on the second mounting bracket 2. The first mounting bracket 1 is slidably connected to the second slide rail 9 through a second slider 10, so that the first mounting bracket 1 and the glue spraying assembly 3 and the blocking member 4 mounted thereon can move relative to the second mounting bracket 2 in the first direction X. Preferably, the second slide rail 9 is located on the side of the second mounting bracket 2, so that Figure 2 the first mounting bracket 1 and its related structures shown are located on one side of the second mounting bracket 2 in the second direction Y, with a reasonable layout, so as to ensure the smooth blocking and glue spraying of the PCBA.

[0044] Preferably, as Figure 2 shown, the glue spraying assembly 3 and the blocking member 4 are located on different sides of the first mounting bracket 1. The up and down movement of the glue spraying assembly 3 is realized by the third driving member to complete the glue spraying on the PCBA; the up and down movement of the blocking member 4 is realized by the second driving member 5 to realize the positioning and blocking of the PCBA. Therefore, setting the glue spraying assembly 3 and the blocking member 4 on different sides of the first mounting bracket 1 in the second direction Y can make the layout more reasonable.

[0045] More preferably, the glue spraying assembly 3 is located on a side of the first mounting frame 1 away from the second mounting frame 2, occupying the mounting surface of the first mounting frame 1 away from the second mounting frame 2 (that is, a side of the first mounting frame 1 perpendicular to the second direction Y). The blocking member 4 is located on a side of the first mounting frame 1 perpendicular to the first direction X, and in the first direction X, the blocking member 4 is located on a side of the glue spraying assembly 3 away from the PCBA material, thereby reducing the movement of the first mounting frame 1 in the first direction X.

[0046] like Figure 3 As shown, the first mounting frame 1 is further provided with a connecting member 6, and the second driving member 5 and the first mounting frame 1 are connected via the connecting member 6. Specifically, there are two connecting members 6, and the two connecting members 6 are spaced apart in the vertical direction Z, so as to stably fix the second driving member 5 on the first mounting frame 1.

[0047] More specifically, the second driving member 5 extends along the vertical direction Z, and has a fixed portion 51 and a movable portion 52, the fixed portion 51 is connected to the connecting member 6, the movable portion 52 is located below the fixed portion 51, and the blocking member 4 is connected to an end of the movable portion 52 away from the fixed portion 51. The second driving member 5 can be a cylinder. The two connecting members 6 are respectively located at both ends of the fixed portion 51 along the vertical direction Z.

[0048] like Figure 1 As shown, the bottom surfaces of the two opposite ends of the second mounting frame 2 along the first direction X can be respectively placed on two third slide rails (not shown) extending along the second direction Y, and the third slide rails are arranged on the upper surface of the fixed workbench, so that the second mounting frame 2 can drive the first mounting frame 1 to move along the second direction Y relative to the workbench.

[0049] In one application scenario, the blocking member 4 is adjusted to an appropriate position by the first and fourth driving members, and then the blocking member 4 is placed in a blocking position by the second driving member 5 to block the delivered PCBA so that the PCBA is located at the working station, and then the blocking member 4 is placed in an avoidance position by the second driving member 5. And by adjusting the position of the blocking member 4 in the first direction X, the center of the blocked PCBA is located at the center of the working station. After the PCBA is corrected by other components of the PCBA packaging device, the glue spraying assembly 3 is adjusted to an appropriate height by the third driving member, and then the glue spraying assembly 3 is driven by the first and fourth driving members to move along the first direction X and the second direction Y to achieve the glue spraying packaging operation of the PCBA.

There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this specification, unless otherwise specified, the meaning of "plurality" is two or more.

[0051] Any numerical values recited herein include all values from the lower value to the upper value incremented by one unit therebetween, provided that there is a separation of at least two units between any lower value and any higher value.

For values less than 1, a unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples of what is intended to be explicitly stated, and all possible combinations of numerical values recited between the lowest value and the highest value are considered to be expressly set forth in this specification in a similar manner.

[0052] Unless otherwise stated, all ranges include the endpoints and all numbers therebetween. The term “about” or “approximate” used in connection with a range is applicable to both endpoints of that range. Thus, “about 20 to 30” is intended to cover “about 20 to about 30”, including at least the specified endpoints.

[0053] All articles and references, including patent applications and publications, are incorporated herein by reference for various purposes. The term “consisting essentially of” describing a combination should include the identified elements, ingredients, components or steps as well as other elements, ingredients, components or steps that do not materially affect the basic novel characteristics of the combination. The use of the terms “comprising” or “including” to describe the combinations of elements, ingredients, components or steps herein also contemplates embodiments consisting essentially of these elements, ingredients, components or steps. By using the term “may” herein, it is intended to indicate that any of the attributes described as “may” include are optional.

[0054] A plurality of elements, ingredients, components or steps can be provided by a single integrated element, ingredient, component or step. Alternatively, a single integrated element, ingredient, component or step can be separated into discrete plural elements, ingredients, components or steps. The disclosure of the articles “a” or “an” used to describe an element, ingredient, component or step does not thereby preclude the presence of other elements, ingredients, components or steps.
