Adjustable dispensing needle micro-distance adjustment mechanism

Abstract

This utility model discloses an adjustable dispensing needle micro-distance adjustment mechanism, applied in the field of clamping device technology. It includes a bracket, with a connecting seat fixedly connected to the horizontal end of the bracket, and an adjusting screw threaded to the top of the connecting seat. By installing the connecting seat on the bracket, and through the action of the fixed seat and the matching seat, rotating the adjusting screw can drive the fixed seat and the matching seat. The limiting grooves on the fixed seat and the matching seat cause the dispensing needle to be slightly adjusted upwards, making the dispensing needle and the dispensing end of the glue tube more tightly locked, preventing separation from the glue tube and ensuring normal dispensing operation. The limiting mechanism allows for quick splicing, fixing, and disassembly of the fixed seat and the matching seat. When the fixed seat descends to a suitable position under the action of the adjusting screw, the fixed seat and the matching seat separate, allowing the connecting end of the dispensing needle to be quickly removed from between the fixed seat and the matching seat, achieving convenient disassembly.

Description

Technical Field

[0001] This utility model belongs to the field of clamping device technology, and specifically relates to an adjustable dispensing needle micro-distance adjustment mechanism. Background Technology

[0002] A dispensing machine is a device used to precisely coat or inject adhesives, colloids, and other materials onto specific locations. It is widely used in many industries such as electronics, automobiles, and medical.

[0003] Currently, the glue removal part of a dispensing machine generally consists of a glue cartridge and a dispensing needle. The glue cartridge is fixed on the mounting base of the dispensing machine, and the dispensing needle is directly fixed to the glue outlet end of the glue cartridge by a snap-fit ​​method. Traditional dispensing machine mounting bases generally only have a fixing structure for fixing the glue cartridge, lacking a structure for fixing and limiting the dispensing needle. During use, the needle and glue cartridge are prone to detachment due to vibration and dispensing pressure, resulting in glue leakage or dripping. Utility Model Content

[0004] The purpose of this invention is to address the adjustable dispensing needle micro-distance adjustment mechanism, which has the advantages of preventing separation and facilitating disassembly.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable dispensing needle micro-distance adjustment mechanism, including a bracket, a connecting seat fixedly connected to the horizontal end of the bracket, an adjusting screw threadedly connected to the top of the connecting seat, one end of the adjusting screw penetrating to the bottom of the connecting seat and rotatably connected to a fixed seat, a fitting seat provided at the bottom of the bracket, a limiting groove provided at the top of both the fixed seat and the fitting seat, a locking block symmetrically fixedly connected to the side of the fixed seat near the fitting seat, a locking groove provided on the fitting seat to engage with the locking block, and an inner groove provided on the opposite side of each of the two locking blocks, with a limiting mechanism provided inside the inner groove.

[0006] The above technical solution is as follows: This utility model has a connecting seat installed on the bracket. Through the action of the fixed seat and the matching seat, when the adjusting screw is rotated, the fixed seat and the matching seat can be driven. The limiting groove on the fixed seat and the matching seat will slightly adjust the distance of the dispensing head upward, so that the dispensing head and the dispensing end of the glue tube are more tightly locked, avoiding separation from the glue tube and ensuring the normal operation of the dispensing work. Through the limiting mechanism, the fixed seat and the matching seat can be quickly spliced, fixed and disassembled. When the fixed seat is lowered to the appropriate position under the action of the adjusting screw, the fixed seat and the matching seat are separated, and the connecting end of the dispensing head can be quickly taken out from between the fixed seat and the matching seat, so as to facilitate disassembly.

[0007] The present invention is further configured such that the limiting mechanism includes a limiting block, and elastic support plates are symmetrically fixedly connected between the limiting block and the inner groove. The front and back of the mounting base are provided with pressing grooves that engage with the limiting block.

[0008] Using the above technical solution: Under the action of the elastic support plate, the limiting block and the pressing groove can be locked together to limit the locking block and the groove and prevent them from separating. When the pressing limit is fast, the locking block and the groove lose their limit and can be quickly separated.

[0009] The present invention is further configured such that a sleeve is provided at the top of the bracket, a rubber tube is snapped into the inside of the sleeve, a limit bolt is threadedly connected to the surface of the sleeve, the output end of the rubber tube extends through to the bottom of the bracket and is snapped into a dispensing head, and the connecting end of the dispensing head is snapped into two limit grooves.

[0010] The above technical solution facilitates the dispensing of adhesive onto the workpiece.

[0011] The present invention is further configured such that the surface of the limiting block is symmetrically equipped with sliders, and the interior of the inner groove is provided with a sliding groove that is slidably connected to the sliders.

[0012] The above technical solution involves sliding the limiting block to facilitate pressing.

[0013] The present invention is further configured such that a mounting base is fixedly connected to one side of the bracket, and the mounting base has a mounting hole.

[0014] The above technical solution facilitates the mounting of the bracket on external travel equipment.

[0015] The present invention is further configured such that a connecting block is bolted inside the bracket, and one side of the connecting block is fixedly connected to the sleeve.

[0016] The above technical solution is adopted to limit and fix the sleeve.

[0017] The present invention is further configured such that sliding rods are symmetrically bolted to the top of the fixed base, and the sliding rods are slidably connected to the connecting base.

[0018] The above technical solution is used to limit the movement of the fixed seat when it is raised or lowered.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model has a connecting seat installed on the bracket. Through the action of the fixed seat and the matching seat, when the adjusting screw is rotated, the fixed seat and the matching seat can be driven. The limiting groove on the fixed seat and the matching seat will adjust the dispensing head upward by a small distance, so that the dispensing head and the dispensing end of the glue tube are more tightly locked, avoiding separation from the glue tube and ensuring the normal operation of the dispensing work.

[0021] 2. This utility model uses a limiting mechanism to quickly connect, fix, disassemble, and separate the fixed seat and the matching seat. When the fixed seat is lowered to the appropriate position under the action of the adjusting screw, the fixed seat and the matching seat are separated, and the connecting end of the dispensing head can be quickly taken out from between the fixed seat and the matching seat, thus achieving the purpose of convenient disassembly.
