Description

Technical Field

[0001] This application relates to the technical field of circuit boards, and more particularly to a main control board for a coffee machine. Background Art

[0002] A coffee machine is a machine used to brew coffee. Existing coffee machines mostly have functions such as preheating, cleaning, grinding, tamping, and brewing. To achieve the above functions, a circuit board is often required, including a main control board.

[0003] Our company currently has a main control board for a coffee machine, as Figure 1 shown, which includes a board body 90. Both middle sections on the two sides of the board body 90 have a pin socket area 901. Each pin socket area 901 has a number of pin holes 9011 arranged in an array. Each pin hole 9011 is a round hole. It should be noted that for external components with multiple pins, such as hybrid signal capacitors, their pins correspond one-to-one with the pin holes 9011. After the assembler inserts each pin into the corresponding pin hole 9011, the pins are then welded to the board body 90 by soldering. However: Since the number of pins on the external component is large, and when inserting into the corresponding pin holes 9011, they need to be inserted simultaneously, and the radial dimension of the pins on the external component is equal to the aperture of the pin holes 9011. Therefore, when one pin on the external component is skewed, it is difficult to initially install the external component on the board body 90. At this time, the assembler needs to straighten the skewed pin before initially installing the external component on the board body 90 to facilitate subsequent soldering, and the assembly efficiency is affected.

[0004] Therefore, there is a need to provide a main control board for a coffee machine that facilitates the insertion of multiple pins, can pre-fix the pins before soldering, and helps improve the assembly efficiency. Summary of the Utility Model

[0021] The terms and words used in the following description and claims are not limited to their literal meanings, but are used only by the present inventor to enable a clear and consistent understanding of the present application. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of the present application is provided only for the purpose of illustration and not for the purpose of limiting the present application as defined by the appended claims and their equivalents.

[0022] It can be understood that the term "a" should be construed as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be construed as a limitation on the number.

[0023] Although ordinal numbers such as "first", "second", etc. will be used to describe various components, those components are not limited herein. The term is only used to distinguish one component from another. For example, the first component can be referred to as the second component, and similarly, the second component can also be referred to as the first component, without departing from the teachings of the inventive concept. The term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0024] The terms used herein are for the purpose of describing various embodiments only and are not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Additionally, it will be understood that the terms "comprising" and / or "having" when used in this specification specify the presence of the stated features, numbers, steps, operations, components, elements, or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements, or groups thereof.

[0025] A schematic main control board for a coffee machine, referring to Figures 2 to 4 , a main control board for a coffee machine according to a preferred embodiment of the present utility model, includes a board body 10. Both middle sections on two sides of the board body 10 each have a pin socket area 101. Each of the pin socket areas 101 has a plurality of pin holes 1011 arranged in an array, and each of the pin holes 1011 is an oval hole.

[0026] It should be noted that the edge of each pin hole 1011 has a chamfer to facilitate the insertion of external pins. It should also be noted that by setting the pin hole 1011 as an oval hole, the width dimension of the pin hole 1011 is equal to the maximum radial dimension of the pins on the external component, and the length dimension of the pin hole 1011 is greater than the maximum radial dimension of the pins on the external component. Compared with the prior art where the pin hole 1011 with the same radial dimension as the pin is circular, when the pins of the external component are skewed in its length direction, since there is more reserved space in the length direction of the oval hole, as long as the pins of the external component are not very significantly skewed in the length direction, they are all easy to insert into the oval hole, facilitating subsequent soldering, and having the advantages of facilitating the insertion of multiple pins and helping to improve the assembly efficiency.

[0027] However, since the pin hole 1011 is an oval hole, even when the pin is inserted into the pin hole 1011, the pins of the external component and the board body 10 are very likely to separate again before being transported to the soldering station.

[0028] In view of this, in the embodiment of the present application, in order to pre-fix the pins after the pins of the external component are inserted into the pin hole 1011, as Figure 2 and Figure 3 shown, the main control board for the coffee machine further includes a plurality of pierceable thin sheet layers 20. Each of the pin row areas 101 is covered with one of the thin sheet layers 20, and the thin sheet layer 20 covers each of the pin holes 1011.

[0029] It should be noted that the thin sheet layer 20 is preferably a transparent or semi-transparent plastic film or thin paper. During assembly, the pins on the external component pierce through and extend into the corresponding pin holes 1011. The thin sheet layer 20 provides a horizontal limit for the pins and a slight friction force in the height direction to prevent the pins of the external component from disengaging from the pin holes 1011 before being transported to the soldering station. Compared with the prior art, it has the advantage of being able to pre-fix the pins before soldering. It should also be noted that when the pins of the external component are inserted into the pin holes 1011, the side of the external component with pins abuts against the thin sheet layer 20. It should also be noted that by setting the thin sheet layer 20, the pin hole 1011 can be regarded as being closed at one end to form a cavity. During soldering, the solder liquid fills this cavity, and since the volume of the oval hole is larger than that of the circular hole, the pins passing through the thin sheet layer 20 and extending into the pin holes 1011 will be more firmly fixed to the board body 10.

[0030] Further, due to the high temperature during the soldering process and the need for insulation between adjacent pins of external components, in the embodiment of the present application, the thin sheet layer 20 is preferably an LCP film. The LCP film has good transparency, insulation, and heat resistance. One side of the thin sheet layer 20 is adhesively connected to the board body 10 through insulating glue and covers each pin hole 1011.

[0031] It should be noted that preferably, before attaching the LCP film to the pin row area 101, a layer of insulating glue is first applied to the pin row area 101, and then the LCP film is attached to the pin row area 101.

[0032] Further, when the LCP film is attached to the pin row area 101, to facilitate the discharge of the overflowing glue, as Figure 2 、 Figure 3 and Figure 4 shown, each pin row area 101 has a first glue discharge groove 1012 and two second glue discharge grooves 1013. The two second glue discharge grooves 1013 are located at both ends of the first glue discharge groove 1012, and one end of the second glue discharge groove 1013 is connected to the first glue discharge groove 1012, and the other end of the second glue discharge groove 1013 extends to the side edge of the board body 10.

[0033] It should be noted that in the embodiment of the present application, the first glue discharge groove 1012, the two second glue discharge grooves 1013, and the side edge of the board body 10 together enclose the pin row area 101; it should also be noted that when the LCP film is attached to the board body 10, the overflowing glue can be discharged along the first glue discharge groove 1012, the second glue discharge groove 1013, and the pin hole 1011. At the same time, when the glue is applied to the pin row area 101, the first glue discharge groove 1012 and the second glue discharge groove 1013 can also prevent the glue from overflowing to other areas of the board body 10.

[0034] Further, to facilitate the glue to flow out from the end of the board body 10, as Figure 2 and Figure 4 shown, the first glue discharge groove 1012 includes two first inclined surfaces 10121. The highest points of the two first inclined surfaces 10121 are adjacent to each other and are located in the middle section of the first glue discharge groove 1012.

[0035] In addition, as Figure 2 and Figure 4 shown, each second glue discharge groove 1013 has a second inclined surface 10131. The highest point of the second inclined surface 10131 is located on the side where the two second glue discharge grooves 1013 face each other, and the lowest point of the second inclined surface 10131 is at the same horizontal height as the lowest point of the first inclined surface 10121.

[0036] Further, for facilitating the connection between the plate body 10 and the mounting seat on the coffee machine, as Figure 2 shown, both ends of the plate body 10 are each provided with at least one connection hole 102, and an external screw can pass through the connection hole 102 to connect with the mounting seat on the coffee machine.

[0037] In summary, the main control board for the coffee machine based on the embodiments of the present application is elucidated, which provides advantages such as facilitating the insertion of multiple pins, being able to pre-fix the pins before soldering, and helping to improve the assembly efficiency for the main control board for the coffee machine.

[0038] It is worth mentioning that in the embodiments of the present application, the main control board for the coffee machine has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the main control board for the coffee machine provided by the present application is easy to produce and has low costs, which is more conducive to controlling production costs and further conducive to the promotion and use of products.
