Description

Technical Field

[0001] This utility model relates to the field of injection valve technology, and in particular to an easy-to-disassemble injection valve. Background Technology

[0002] In the field of surface mount technology (SMT), solder paste ejection valves are core components of precision dispensing equipment, and their performance directly affects production efficiency and product quality. Existing solder paste ejection valves typically consist of two parts: the valve body and the cartridge connector assembly. The main function of the cartridge connector assembly is to connect the solder paste cartridge to the ejection valve body, ensuring that the solder paste is stably and accurately delivered to the ejection valve body for ejection under pressure.

[0003] Currently, the solder paste cartridge connector assembly and the injection valve body are mainly connected by bolts. This bolt-locking method is cumbersome in practice, requiring operators to use tools to tighten or loosen the bolts, making the assembly and disassembly process extremely inconvenient. This inconvenience is particularly pronounced when frequent solder paste cartridge changes or equipment cleaning and maintenance are needed, severely restricting the changeover efficiency of the production line.

[0004] Therefore, the existing injection valve needs to be improved to solve the problem that the injection valve body and the rubber sleeve connector assembly are locked with bolts, which makes assembly and disassembly inconvenient.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide an easy-to-disassemble injection valve that effectively solves the problem that the injection valve body and the rubber sleeve connector assembly of existing injection valves are locked with bolts, resulting in inconvenience in assembly and disassembly.

[0059] Nozzle 302, which is installed at the bottom of the connector body 301 and connected to the lower opening of the glue dispensing channel 3012;

[0060] The sliding ejector pin 303 slides downward from above the vertical rotating shaft 2, passes through the vertical rotating shaft 2, and extends into the glue outlet channel 3012. It is used to squeeze the glue material in the glue outlet channel 3012 downward after being driven, and then spray it out through the nozzle 302.

[0061] A pin spring 304 is sleeved on the sliding pin 303 and located above the vertical rotating shaft 2, and is used to drive the sliding pin 303 to slide upward relative to the vertical rotating shaft 2 until it disengages from the nozzle 302.

[0062] Accordingly, the injection valve body 1 includes:

[0063] The valve body housing 101 has an internal accommodating cavity. The bottom surface of the valve body housing 101 has a positioning rotation groove 1011 for the top of the vertical rotating shaft 2 to be inserted upward and connected to the accommodating cavity. The side surface of the valve body housing 101 has a connector slot 1012. The top of the positioning rotation groove 1011 has a needle groove for the ejector spring 304 to pass through.

[0064] A linear drive mechanism 102 is installed in the accommodating cavity and is used to press down on the top of the sliding ejector pin 303 so that the sliding ejector pin 303 slides down and sprays the adhesive in the dispensing channel 3012 outward through the nozzle 302.

[0065] The linear drive mechanism 102 includes:

[0066] A rotating pressure plate 1021, one end of which is hinged to the valve body housing 101, and the other end abuts against the top surface of the sliding pin 303;

[0068] Optionally, the easy-to-disassemble injection valve also includes:

[0069] Rotary cover plate 4 is hinged to the injection valve body 1 to cover the side opening of the connector slot 1012;

[0070] The hand-tightening locking member 5 passes through the outside of the rotating cover plate 4 and is threadedly connected to the injection valve body 1.

[0071] The easy-to-disassemble injection valve provided in this embodiment operates as follows:

[0072] I. Installation process of injection valve body 1

[0073] 1. Positioning of vertical pivot component 2:

[0074] After the sliding ejector pin 303 passes through the ejector spring 304 and the vertical rotating shaft 2 in sequence, the lower end of the sliding ejector pin 303 is inserted into the upper opening of the glue dispensing channel 3012, thereby achieving a seal at the upper end of the glue dispensing channel 3012.

[0075] At this time, the upper end of the vertical rotating shaft 2 is exposed above the connector body 301.

[0076] 2. Connecting of rubber sleeve connector assembly 3:

[0077] Hold the rubber tube connector assembly 3 and align the upper end of the vertical rotating shaft 2 with the positioning rotating groove 1011 of the valve body housing 101.

[0078] Push the connector body 301 upwards, and the upper end of the vertical rotating shaft 2 is inserted into the positioning rotating groove 1011. The horizontal translation limit is completed by the insertion of the vertical rotating shaft 2 and the connector body 301 (only translation is limited, rotation is not limited).

[0079] 3. Rotary locking:

[0080] Rotate the rubber tube connector assembly 3 in the positive direction with the vertical rotating shaft 2 as the axis, so that its other end (the snap-fit ​​part 3014 of the connector body 301) is rotated and snapped into the connector slot 1012 on the side of the valve body housing 101.

[0081] The lateral opening structure of the connector slot 1012 completely restricts the vertical freedom of the rubber tube connector assembly 3 and locks its relative position.

[0082] 4. Cover and lock the rotating cover plate 4:

[0083] The rotating cover plate 4, which is hinged to the injection valve body 1, has a side opening in the cover joint slot 1012.

[0084] Tighten the hand-tightening locking part 5 so that it passes through the rotating cover plate 4 and is threadedly connected to the injection valve body 1, further reinforcing the rotating cover plate 4.

[0085] II. Controlling the glue output

[0086] 1. The solder paste cartridge is connected to the glue cartridge interface 3011 of the connector body 301, and the solder paste flows into the middle of the glue outlet channel 3012 through the inclined flow channel 3013.

[0087] 2. The piezoelectric ceramic 1022 is vertically mounted on the top of the rotating pressure plate 1021, providing downward power for the sliding ejector pin 303. After the piezoelectric ceramic 1022 is energized, it pushes the rotating pressure plate 1021 downward; the rotating pressure plate 1021 squeezes the sliding ejector pin 303 downward, squeezing the adhesive material in the dispensing channel 3012 into the nozzle 302 for ejection.

[0088] 3. After power is cut off, the ejector spring 304 drives the sliding ejector pin 303 to slide upward, disengage from the nozzle 302, and stop dispensing glue.

[0089] III. Disassembly Process

[0090] 1. Loosen and remove the hand-tightening locking piece 5, and open the rotating cover 4 to expose the connector slot 1012.

[0091] 2. Rotate the rubber tube connector assembly 3 in the opposite direction to disengage the snap-fit ​​part 3014 from the connector slot 1012.

[0092] 3. Pull down the rubber tube connector assembly 3 so that the vertical rotating shaft 2 drives the sliding ejector pin 303 and ejector pin spring 304 to move downward and disengage from the injection valve body 1.

[0093] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
