Description

Technical Field

[0001] This utility model relates to the field of glue dispensing device technology, and in particular to a high-precision glue dispensing mechanism. Background Technology

[0002] In the processing of some electronic components, the materials are mounted on the surface of the circuit board. After the glue is applied to the surface of the circuit board by the glue dispensing mechanism, the object is directly bonded to the surface of the circuit board. The glue dispensing mechanism is a device that applies adhesive material to the surface of the workpiece.

[0003] A glue applicator is a tool for applying or extruding glue. It can be used wherever glue is needed and is widely used in industries such as building decoration, electronics, automobiles and auto parts, ships and containers. Of course, glue is also needed in the production of bottle caps, and glue applicator devices are required. Generally, the metal sheet is placed on the fixture manually, and then glue is added to the metal sheet. Each set of fixtures is equipped with a clamping device. Then the glass is placed on the fixture and squeezed by the fixture. After clamping, the fixture and the product are initially cured in a UV cold light oven. After cleaning, applying glue, and cleaning, it is finally cured in a UV oven.

[0004] The glue-dispensing device has the following drawbacks: the glue is added manually, so the amount of glue added each time is uncertain. Therefore, in order to meet the required bonding strength between the metal sheet and the glass, more glue is usually added, which causes excess glue to overflow and lead to glue waste. To address this issue, a high-precision glue-dispensing mechanism is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-precision glue dispensing mechanism, which aims to improve the problem of excess glue overflow and waste caused by the existing technology of adding more glue to meet the requirements.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-precision glue dispensing mechanism, comprising a lifting platform, a base, a support, a glue dispensing machine, a glue storage box frame, and a glue dispensing controller, characterized in that: a mixing mechanism is provided on the glue storage box frame, an auxiliary mechanism is provided on the support, the mixing mechanism includes a through pipe fixedly connected to the rear outer wall of the glue storage box frame, a mixing box fixedly connected to the end of the through pipe away from the glue storage box frame, a pre-setting cylinder slidably connected to the side outer wall of the mixing box, a measuring scale fixedly connected to the front outer wall of the pre-setting cylinder, a discharge port opened on the left inner wall of the pre-setting cylinder, a compression spring fixedly connected to the bottom outer wall of the mixing box, a sloping opening opened on the right inner wall of the mixing box, and a glue dispensing pipe fixedly connected to the rear outer wall of the pre-setting cylinder.

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a rotating column, which is rotatably connected to the inner walls of the left and right sides of the bracket via bearings. A fixed frame is fixedly connected to the rotating column. An adjusting plate is slidably connected to the inner wall of the left side of the rotating column. A slot is opened on the outer wall of the left side of the bracket. A telescopic spring is fixedly connected to the outer wall of the left side of the adjusting plate. A magnifying glass is fixedly connected to the inner wall of the front side of the fixed frame.

[0008] As a further description of the above technical solution: the pre-set cylinder is fixedly connected to the top outer wall of the glue storage box frame, and the end of the compression spring away from the mixing box is fixedly connected to the bottom inner wall of the discharge port.

[0009] As a further description of the above technical solution: the mixing box is slidably connected to the left outer wall of the pre-set cylinder, and the discharge port is connected to the inclined opening.

[0010] As a further description of the above technical solution: a pressing plate is fixedly connected to the top outer wall of the mixing box, and the end of the dispensing tube away from the pre-set cylinder is fixedly connected to the outer wall of one side of the dispensing machine.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting up a pre-set cylinder, a measuring ruler, a discharge port and other structures, the amount of glue injected is precisely controlled, so that the amount of glue injected is controlled to a certain extent, preventing excessive glue during injection. The glue is added manually, so the amount of glue added each time is uncertain. However, in order to make the connection strength of the glue injection position meet the requirements, more glue is usually added, which causes excess glue to overflow and waste glue.

[0016] 2. In this utility model, by setting a slot, a telescopic spring, a magnifying glass and other structures, the glue injection area is magnified by the magnifying glass, which makes it easier for personnel to observe the small parts of the glue injection area, and facilitates personnel operation and adjustment. This improves the problem that it is difficult for personnel to observe the glue injection point with the naked eye, which leads to the problem of glue injection deviation.

[0027] Working principle: Adhesive is pre-filled into the mixing box 72 via the through-tube 71. The precise amount of adhesive is prepared by observing the volume of adhesive in milliliters through the pre-positioned cylinder 73 using the graduated scale 74. Then, the pressing plate 78 is pressed down, causing the mixing box 72 to move downwards until the inclined outlet 77 aligns with the discharge outlet 75, allowing the adhesive in the mixing box 72 to flow into the pre-positioned cylinder 73. The adhesive is then drawn in through the dispensing pipe 79 by the dispensing machine 4 and applied to the desired area, minimizing waste. Simultaneously, during dispensing, the adjusting plate 83 is pulled out of the slot 84, and then the adjusting plate 83 is rotated, causing the rotating column 81 to rotate. The rotation of the rotating column 81 drives the fixing frame 82 to rotate, adjusting the angle of the magnifying glass 86. This allows personnel to magnify and observe the dispensing area through the magnifying glass, facilitating operation and adjustment.
