Description

Technical Field

[0001] The utility model relates to the technical field of dispensing, and in particular, to a dispensing head and a dispensing device. Background Art

[0002] Dispensing, also known as glue application, coating, potting or drop dispensing, is to apply, pot or drop electronic glue, oil or other liquids onto products to make the products play roles such as adhesion, potting, insulation, fixation and surface smoothness. In the dispensing process, many glues contain solid particles, such as solder paste, silver paste and silica gel containing SiO2 particles. For these glues containing solid particles, under the continuous action of dispensing pressure, the solid particles inside are extremely easy to adhere to the side wall of the dispensing head, resulting in the blockage of the dispensing head, directly affecting the stability of glue dispensing or the phenomenon of no glue dispensing.

[0003] Currently, in the industry, there is no good solution to the problem that the glue is easy to adhere to the side wall, thus affecting the stability of glue dispensing. The common practice is to directly replace the blocked dispensing head or clean it with a fine needle or an ultrasonic instrument. However, frequently replacing the dispensing head will increase the cost, and after each replacement of the dispensing head, the position correction of the dispensing head is required, which will affect the operation efficiency; while using the method of cleaning with a fine needle or ultrasonic can improve this situation, but it will also waste a lot of time and affect the operation efficiency.

[0028] Please refer to Figure 1 , this embodiment provides a dispensing head 20, which includes a glue storage device 10 and a glue head 20 connected to one end of the glue storage device 10; the glue storage device 10 has at least two glue storage cavities 11 and a connection channel 12, and any two glue storage cavities 11 are communicated through the connection channel 12, and the connection point of the glue storage cavity 11 and the connection channel 12 is located on the side wall of the glue storage cavity 11; the glue head 20 has a through dispensing channel 21, one end of the dispensing channel 21 is respectively communicated with at least two glue storage cavities 11, and the other end of the dispensing channel 21 is used for dispensing. This dispensing head 20 can improve the problem that the dispensing head 20 in the prior art is easy to be blocked, and reduce the influence on the dispensing operation efficiency caused by the blockage of the dispensing head 20.

[0029] It should be noted that the dispensing head 20 of the present application can be used in the dispensing process of semiconductor devices. The dispensing head 20 includes a glue storage device 10 and a glue head 20. Among them, the glue storage device 10 is used to store glue, and the glue head 20 is communicated with the glue storage device 10 and is used to output the glue stored in the glue storage device 10 through the glue head 20, so as to perform dispensing through the glue head 20.

[0030] In this embodiment, the glue reservoir 10 has a glue storage cavity 11 and a connection channel 12. Among them, there are at least two glue storage cavities 11, and any two glue storage cavities 11 can be communicated through the connection channel 12. In addition, the connection point of the glue storage cavity 11 and the connection channel 12 is located at the side wall of the glue storage cavity 11. In this way, for the dispensing head 20 of the present application, due to the setting of the connection channel 12, the fluidity of the glue in the glue storage cavity 11 can be enhanced, and the phenomenon that the glue adheres to the inner wall of the glue storage cavity 11 can be improved.

[0031] The above-mentioned dispensing head 20 has a dispensing channel 21, which penetrates through the dispensing head 20. One end of the dispensing channel 21 is communicated with the glue storage cavity 11, and the other end is used for dispensing. It should be noted that the dispensing channel 21 is communicated with the glue outlet 113 of the glue storage cavity 11. In this way, the glue in the glue storage cavity 11 can more conveniently enter the dispensing channel 21, which is beneficial to the flow of the glue and can effectively utilize the glue.

[0032] In summary, the dispensing head 20 provided by the present application includes a glue reservoir 10 and a dispensing head 20 connected to one end of the glue reservoir 10; the glue reservoir 10 has at least two glue storage cavities 11 and a connection channel 12, and any two glue storage cavities 11 are communicated through the connection channel 12. The connection point of the glue storage cavity 11 and the connection channel 12 is located at the side wall of the glue storage cavity 11; the dispensing head 20 has a through dispensing channel 21, one end of the dispensing channel 21 is respectively communicated with at least two glue storage cavities 11, and the other end of the dispensing channel 21 is used for dispensing. By setting the connection channel 12 in the present application, and communicating any two glue storage cavities 11 through the connection channel 12, and making the connection point of the glue storage cavity 11 and the connection channel 12 located at the side wall of the glue storage cavity 11, in this way, during the dispensing process, the glue can enter the connection channel 12 through the side wall of the glue storage cavity 11, so as to improve the fluidity of the glue and avoid the glue adhering to the side wall of the glue storage cavity 11 during the dispensing process. The dispensing head 20 of the present application can improve the problem that the dispensing head 20 in the prior art is easy to be blocked, reduce the risk of unstable dispensing caused by the blockage of the dispensing head 20, and compared with the cleaning methods such as replacing the dispensing head 20 or using a thin needle and an ultrasonic instrument for the blockage of the dispensing head 20 in the prior art, since the dispensing head 20 of the present application can reduce the blockage risk, it can also reduce the cleaning or replacement times of the dispensing head 20, thereby improving the dispensing operation efficiency.

[0033] Please refer to Figure 2 , optionally, the dispensing head 20 further includes a mounting post 30. One end of the mounting post 30 is fixed inside the glue reservoir 10, and the other end extends outside the glue reservoir 10; the mounting post 30 has a through mounting hole 31, and one end of the mounting hole 31 is communicated with the glue storage cavity 11 through the connection channel 12. It should be noted that the dispensing head 20 can be fixed to the pump body of the dispensing device through the mounting post 30.

[0034] In this embodiment, the mounting post 30 is provided with a through mounting hole 31, one end of which extends into and is fixed to the glue storage container 10, and one end of the mounting hole 31 is connected to the connecting channel 12, and the other end extends out of the glue storage container 10, so that the mounting hole 31 of the mounting post 30 can also be used for glue to flow, which can further improve the fluidity of the glue in the dispensing head 20. In addition, the setting of the mounting hole 31 can also facilitate the cleaning of the connecting channel 12 through it.

[0035] The present application does not limit the size and shape of the mounting column 30 and the mounting hole 31 , and those skilled in the art may make their own selections based on actual conditions.

[0036] In addition, in order to protect the glue or facilitate cleaning of the mounting hole 31, optionally, in this embodiment, the dispensing head 20 may further include a mounting cap 40, which is detachably connected to the end of the mounting column 30 away from the connecting channel 12 to cover or open the mounting hole 31. In this way, when the mounting cap 40 is opened to open the mounting hole 31, it is convenient to clean the mounting hole 31; when the mounting cap 40 is installed to cover the mounting hole 31, the glue in the mounting hole 31 can be effectively protected.

[0037] It should be noted that the mounting cap 40 can be connected to the mounting column 30 by threading, snap-fitting, etc., and the present application does not impose any specific restrictions on the detachable manner of the mounting cap 40 and the mounting column 30.

[0038] In this embodiment, optionally, the glue storage chamber 11 has a glue inlet 111, a glue storage channel 112, and a glue outlet 113, the glue inlet 111 and the glue outlet 113 are arranged opposite to each other, and the glue storage channel 112 is connected to the glue inlet 111 and the glue outlet 113. In other words, the glue inlet 111, the glue storage channel 112, and the glue outlet 113 are connected in sequence, and the glue inlet 111, the glue storage channel 112, and the glue outlet 113 are linearly distributed. That is, the glue inlet 111, the glue storage channel 112, and the glue outlet 113 are located on the same straight line, so that the colloid in the glue storage chamber 11 flows more smoothly, which can improve the fluidity of the glue and improve the problem of easy clogging of the dispensing head 20.

[0039] Also, in this embodiment, optionally, the radial dimension of the glue storage channel 112 gradually decreases from the glue inlet 111 toward the glue outlet 113. It should be noted that the radial dimension of the glue storage channel 112 is gradually converged in this application, so that the glue dispensing head 20 of this application can be applied to the semiconductor dispensing process.

[0040] Optionally, the axial cross section of the glue storage channel 112 may be trapezoidal, such as Figure 1Of course, the shape of the glue storage channel 112 is only an example and is not intended to limit the present application.

[0041] In addition, it should be noted that, in this embodiment, the present application does not limit the connection between the glue storage chamber 11 and the connecting channel 12, and a suitable position can be selected as needed.

[0042] For example, in a feasible implementation, optionally, at least one connection point between the glue storage chamber 11 and the connecting channel 12 is located on a different horizontal line from the connection points between the other glue storage chambers 11 and the connecting channel 12. That is, at least one connection point between the glue storage chamber 11 and the connecting channel 12 is not at the same height as the connection points between the other glue storage chambers 11 and the connecting channel 12. In other words, the distance from the connection point between at least one glue storage chamber 11 and the connecting channel 12 to the glue head 20 is not equal to the distance from the connection point between the other glue storage chambers 11 and the connecting channel 12 to the glue head 20. For example, the glue storage chamber 11 includes three, two of which have connection points between the glue storage chamber 11 and the connecting channel 12 located at a first height of the glue storage chamber 11, and another connection point between the glue storage chamber 11 and the connecting channel 12 located at a second height of the glue storage chamber 11, and the first height and the second height are different.

[0043] For another example, in another feasible implementation, optionally, each glue storage cavity 11 is located on the same horizontal line with the connection point of the connection channel 12. That is, the connection points of all glue storage cavities 11 and the connection channel 12 are at the same height, in other words, the distances from the connection points of all glue storage cavities 11 and the connection channel 12 to the glue head 20 are equal.

[0044] Also, optionally, in this embodiment, the glue storage chamber 11 may include multiple glue storage chambers 11. When the glue storage chamber 11 includes multiple glue storage chambers 11, the multiple glue storage chambers 11 are distributed on the periphery of the connecting channel 12. In this way, it is convenient for the connecting channel 12 to connect different glue storage chambers 11, and the internal structure of the glue dispensing head 20 can be simplified.

[0045] Another aspect of the present invention provides a dispensing device, which includes a pump body and the above-mentioned dispensing head 20, wherein the pump body is connected to an end of the dispensing head 20 of the dispensing head 20 away from the dispensing head 20 and the dispensing head 20. The specific structure and technical effects of the dispensing head 20 have been described in detail above, so this application will not repeat them here.

[0046] The above description is only an optional embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0047] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present utility model will not separately describe various possible combination manners.
