Description

Technical Field

[0001] The utility model relates to the technical field of AF electroplating pill processing equipment, in particular to a glue dispensing mechanism. Background Art

[0002] AF electroplating pills are a special material used in the electroplating process. They are mainly used to form a thin film with specific functions on the surface of an object. AF electroplating pills are widely used in mobile phone screens, 3C industry glass, digital camera glass and other fields that require high clarity, high wear resistance and anti-fingerprint properties.

[0003] In the production process of AF electroplated pills, glue dispensing is used to coat a layer of protective glue, adhesive or other functional materials on the surface of the pills to enhance the pills' anti-fingerprint performance, wear resistance, corrosion resistance or to achieve other specific functions. In the prior art, during the processing of AF pills, it is necessary to perform glue dispensing on the AF pills. However, the current glue dispensing method is generally for the staff to manually pick up the AF pills and then dispense glue through a glue dispensing gun. The glue dispensing gun includes a glue barrel and a push rod. The glue barrel is fixed with an annular wing, and the push rod is fixed with a push handle. In this way, the staff first needs to hold the glue barrel and push the push rod to dispense glue, and also needs to hold the AF pills, which makes the operation inconvenient and the force of squeezing the push rod uneven, resulting in uneven glue coverage of the AF pills, and it is also impossible to control the amount of glue dispensed each time. Utility Model Content

[0004] The utility model aims to provide a dispensing mechanism to solve the problems of uneven dispensing of AF pills and inability to control the dispensing amount in the prior art.

[0005] In order to solve the above problems, the present invention provides the following technical solutions:

[0006] A dispensing mechanism includes a workbench, the workbench is fixedly provided with a bracket, the bracket is fixedly provided with a cylinder, the bracket is vertically slidably connected to a lifting platform, the movable end of the cylinder is coaxially connected to a reciprocating screw rod passing through the lifting platform, the lifting platform and the reciprocating screw rod are used in conjunction with each other for lifting, the lifting platform is provided with a first notch for clamping a push rod, the lifting platform is bolted with a first pressure plate for pressing the push handle; the bracket is fixed with a support platform, the support platform is provided with a second notch for clamping a rubber cylinder, and the support platform is bolted with a second pressure plate for pressing the annular wing.

[0007] The working principle and beneficial effects of this utility model:

[0008] When using this solution, the rubber cylinder is inserted into the support platform through the second notch, the push rod is inserted through the first notch, the support platform supports the syringe through the annular wing, the lifting platform is located directly below the push handle, and the lifting platform and the bracket are vertically slidably connected, thereby limiting the lifting platform to only slide in the vertical direction, and the lifting platform is driven to slide upward by rotating the reciprocating screw until the lifting platform rises and contacts with the push handle, and then the first pressing plate and the second pressing plate are installed, the annular wing is fixed between the second pressing plate and the support platform, and the needle handle is fixed between the first pressing plate and the lifting platform.

[0009] By holding the AF pill at the glue outlet of the rubber cylinder, the reciprocating screw and the lifting platform are driven downward by the cylinder, the support platform supports the rubber cylinder through the annular wings, and the first pressure plate squeezes the push rod downward through the needle handle, and the glue discharged from the glue outlet of the rubber cylinder is smeared on the AF pill. Since the cylinder squeezes the push rod downward linearly and evenly, the glue discharged from the glue outlet of the rubber cylinder is also even, thereby solving the problems of uneven dispensing of AF pills and uncontrollable dispensing amount in the prior art.

[0010] Furthermore, one side of the first pressing plate is rotatably connected to the lifting platform, and one side of the second pressing plate is rotatably connected to the support platform. When the lifting platform contacts the needle handle, the first pressing plate is rotated to be directly above the needle handle and connected to the lifting platform. Similarly, when the support platform contacts the annular wing, the second pressing plate is rotated to be directly above the annular wing and connected to the support platform.

[0011] Furthermore, the cylinder is fixedly mounted on the top of the bracket. This optimized solution can meet the maximum stroke of the cylinder, thereby facilitating the extrusion of the rubber cylinder for rubber discharge.

[0012] Furthermore, the second pressing plate is an annular plate provided with a third notch, wherein the third notch is used for the push rod to enter, so that the second pressing plate can squeeze the annular wing.

[0013] Furthermore, the cylinder is electrically connected to a controller, which precisely controls the extension and contraction of the movable end of the cylinder, thereby precisely controlling the amount of glue discharged.

[0014] Furthermore, the first pressing plate and the second pressing plate are both elastic plates, which have better fixing and squeezing effects. BRIEF DESCRIPTION OF THE DRAWINGS

In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0023] Example: Refer to Figure 5 The dispensing gun includes a glue cylinder 4 and a push rod 9. The glue cylinder 4 is fixedly sleeved with an annular wing 11, and the push rod 9 is fixedly provided with a push handle 12.

[0024] like Figure 1 and Figure 4 As shown, a dispensing mechanism includes a workbench 6, the workbench 6 is fixed with a bracket 13, the top of the bracket 13 is fixed with a cylinder 1, the bracket 13 is vertically slidably connected to the lifting platform 3, the movable end of the cylinder 1 is coaxially connected to the reciprocating screw 2 passing through the lifting platform 3, and the lifting platform 3 and the reciprocating screw 2 are used together for lifting (that is, the lifting platform 3 and the reciprocating screw 2 are threadedly connected to form a screw slider structure).

[0025] The lifting platform 3 is provided with a first notch for clamping the push rod 9, and the lifting platform 3 is bolted and fixedly connected with a first pressure plate 10 for pressing the annular wing 11; the bracket 13 is fixedly provided with a support platform 7, and the support platform 7 is provided with a second notch for clamping the rubber cylinder 4, and the support platform 7 is bolted and fixedly connected with a second pressure plate 8 for pressing the annular wing 11, and the second pressure plate 8 is provided with a third notch for the push rod 9 to pass through.

[0026] like Figure 2 and Figure 3As shown, when this solution is used, the rubber cylinder 4 is inserted into the support platform 7 through the second notch, the push rod 9 is inserted through the first notch, the support platform 7 supports the syringe 4 through the annular wing 11, and the lifting platform 3 is located directly below the push handle 12. The lifting platform 3 and the bracket 13 are vertically slidably connected, thereby limiting the lifting platform 3 to slide only in the vertical direction. The lifting platform 3 is driven to slide upward by rotating the reciprocating screw 2 until the lifting platform 3 rises and contacts with the push handle 12, and then the first pressure plate 10 and the second pressure plate 8 are installed by bolts, and the push rod 9 is located in the third notch on the second pressure plate 8, and the annular wing 11 is fixed between the second pressure plate 8 and the support platform 7, and the needle handle is fixed between the first pressure plate 10 and the lifting platform 3.

The first pressing plate 10 squeezes the push rod 9 downward through the needle handle, and the glue at the glue outlet of the glue cylinder 4 is smeared on the AF pill 5. Since the cylinder 1 squeezes the push rod 9 downward linearly and evenly, the glue at the glue outlet of the glue cylinder 4 is also even, thereby solving the problems of uneven glue dispensing and uncontrollable glue dispensing amount of the AF pill 5 in the prior art.
