Description

Technical Field

[0001] The present application relates to the field of equipment for gluing optical couplers, and in particular to an optical coupler surface gluing equipment and a gluing process. Background Art

[0002] Optocoupler surface glue coating equipment is widely used in the manufacturing process of electronic components, especially in the production line of optocouplers. With the increasingly obvious trend of miniaturization and integration of electronic products, the requirements for optocoupler surface glue coating are also getting higher and higher.

[0003] In the existing technology, in order to solve the problem of gluing on the surface of the optical coupler, the following methods are usually used: one is to use a manual dispensing gun for gluing. This method is simple and easy, but manual operation can easily lead to uneven glue amount and low efficiency; the second is to use a nozzle-type automatic gluing machine. This equipment achieves uniform gluing by precisely controlling the position and speed of the nozzle.

[0004] However, the above methods still have some problems in practical application; especially for products such as optocouplers that require precise control of the amount and shape of the colloid, the traditional method is difficult to effectively solve the phenomenon of colloid drawing, which will cause the colloid to adhere to unnecessary places and affect product quality. Therefore, how to reduce the phenomenon of colloid drawing is an urgent problem to be solved. Summary of the invention

[0005] In order to reduce the colloid wire drawing phenomenon, the present application provides an optical coupler surface glue coating device and a glue coating process.

[0006] In the first aspect, the present application provides an optical coupling surface glue coating device, which adopts the following technical solution: An optical coupler surface glue coating device, comprising: frame; a glue delivery pipe having a glue outlet, the glue delivery pipe being arranged parallel to the first direction, the glue delivery pipe being connected to the frame; and, A cutting assembly, the cutting assembly comprising: A mounting frame connected to the frame; and Two cutting blocks with cutting surfaces, in a first direction, the cutting blocks are located outside the glue outlet of the glue feeding tube; the two cutting blocks are distributed in sequence in a second direction, and the sides of the two cutting blocks close to each other are the cutting surfaces, and the cutting blocks are slidably connected to the mounting frame along the second direction, so that the cutting blocks can be adjusted between a cutting posture and a glue feeding posture; When the cutting blocks are in a cutting posture, the cutting surfaces of the two cutting blocks are in contact with each other; When the cutting block is in the glue feeding posture, a material passing gap is formed between the cutting surfaces of the two cutting blocks.

[0007] By adopting the above technical solution, the two cutting blocks of the cutting assembly can slide along the second direction under the action of the driving cylinder, so that they can contact each other to form a closed state when needed, effectively cutting off the colloid and reducing the occurrence of colloid wiredrawing; and when there is no need to cut the colloid, the material gap formed between the two cutting blocks can ensure that the colloid flows smoothly onto the chip.

[0008] Optionally, the cutting surface is wavy in a cross section perpendicular to the first direction.

[0009] By adopting the above technical solution, the cross section of the cutting surface perpendicular to the first direction is designed to be wavy, which can separate the colloid into multiple strips along the third direction, reduce the overall diameter of the colloid, and effectively reduce the occurrence of colloid wire drawing.

[0010] Optionally, the cutting surface, along a cross section perpendicular to the third direction, is in the shape of an arc that is concave toward one side of one of the cutting blocks.

[0011] By adopting the above technical solution, the cross section of the cutting surface along the third direction is designed to be concave toward one side of one of the cutting blocks, which can cut the colloid in the first direction and further reduce colloid stringing.

[0012] Optionally, the wall surface of the cutting block close to the glue feeding tube is a material receiving surface; in the first direction, a drop gap is formed between the material receiving surface and the glue outlet end wall of the glue feeding tube.

[0013] By adopting the above technical solution, the drop gap formed between the material receiving surface and the end wall of the glue outlet of the glue delivery hose can facilitate personnel to insert their hands or other tools into the glue outlet to peel off the solidified colloid, thereby effectively reducing the problem of normal operation of the equipment being affected by colloid solidification.

[0014] Optionally, the two material receiving surfaces are inclined toward the glue outlet on a side that is close to each other.

[0015] By adopting the above technical solution, the design of the two material connection surfaces being inclined toward the glue outlet side toward the side close to each other can guide the cut colloid to flow to both sides, effectively avoiding the accumulation of colloid at the joint of the two material connection surfaces, thereby reducing equipment failure and maintenance frequency caused by colloid accumulation.

[0016] Optionally, each of the cutting blocks is fixedly connected with a corresponding stop bar, the stop bar has a material blocking surface, and the stop bar is located on a side of the cutting block close to the glue feeding pipe; The two material blocking surfaces are inclined toward a side close to each other and a side away from the glue outlet, so that a material receiving area is formed between the material blocking surface and the material receiving surface.

[0017] By adopting the above technical solution, the design of the baffle bar and the material receiving surface can effectively prevent the colloid from falling off the cutting block. Specifically, the material receiving surface on the baffle bar is inclined toward the side close to each other and away from the glue outlet, so that a material receiving area is formed between the material receiving surface and the material receiving surface, and the colloid falls along the material receiving surface into the material receiving area, reducing the risk of the colloid falling directly from the cutting block.

[0018] Optionally, a suction component is also included, and the suction component includes: A material collecting box having an air outlet and a material inlet; and, A vacuum pump having an air outlet, wherein the air outlet of the vacuum pump is connected to the air outlet of the collecting box; The blocking bar and / or the cutting block is provided with a first discharge hole, one end of the first discharge hole is communicated with the material receiving area, and the other end of the first discharge hole is communicated with the feed port of the material collecting box.

[0019] By adopting the above technical solution, the suction component can effectively collect the colloid residue generated during the cutting process. Specifically, the combined design of the collection box and the vacuum pump allows the cut colloid to smoothly enter the collection box through the first discharge hole, avoiding the problem of equipment blockage caused by colloid residue, and improving the cleanliness and maintenance convenience of the equipment. At the same time, the design of the material receiving area ensures that the colloid can flow into the first discharge hole in an orderly manner, further enhancing the collection efficiency of the colloid.

[0020] Optionally, a heating wire is embedded in the baffle bar and / or the cutting block.

[0021] By adopting the above technical solution, when a heating wire is embedded in the baffle and / or the cutting block, the colloid can be heated to make it easier to flow and be collected in the collection box through the first discharge hole and the second discharge hole, thereby effectively reducing the residue of colloid on the cutting block and improving the cleanliness and working efficiency of the equipment.

[0022] Optionally, it further includes a cross slide having a driving part, the cross slide is fixedly connected to the frame, the sliding direction of the driving part of the cross slide is perpendicular to the first direction, and the mounting frame is fixedly connected to the driving part.

[0023] By adopting the above technical solution, the driving part of the cross slide can move on the reference plane, so that the mounting frame and the cutting block thereon can be accurately moved to the required position on the reference plane, thereby improving the flexibility and precision of the equipment and ensuring the accuracy and reliability of the colloid cutting process.

[0024] In a second aspect, the present application provides a process for coating an optical coupler surface with glue, which adopts the following technical solution: A process for coating the surface of an optical coupler, using the aforementioned coating equipment, is characterized in that it includes the following steps: S1: Place the chip on the base; S2: Open the valve to drip the colloid in the glue delivery tube to between the two optocouplers on the chip; after the colloid drips, if the cutting block needs to be cleaned, just energize the heating wire and let the vacuum machine collect the colloid in the first discharge hole and the second discharge hole into the collection box through the main discharge hole; S3: Send the chip coated with colloid to a drying box for drying.

[0025] By adopting the above technical solution, when the colloid is cut by a cutting block, the occurrence of wire drawing of the colloid can be effectively reduced.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The cutting assembly can accurately cut the colloid through the relative movement of the two cutting blocks in the second direction, reducing the occurrence of colloid drawing and improving the quality and reliability of glue coating; 2. The wavy cutting surface design can divide the colloid into multiple small parts, further reduce the diameter of the colloid, reduce overall wire drawing, and ensure uniformity and stability during the gluing process; 3. The drop gap design between the material receiving surface and the glue outlet makes it convenient for personnel to clean the solidified colloid at the glue outlet, ensuring the continuous and efficient operation of the equipment.
