[0002] The glue developer is a kind of equipment in the production of printed circuit boards, which is used to manufacture the lead patterns in PCBs. The working principle of the glue developer can be divided into three steps: glue coating, development, and cleaning. Among them, glue coating is the first step of the glue developer. The specific process is: the photosensitive glue is evenly heated and applied on the printed circuit board (PCB), so that it dries under the sunlight or other specific light.

[0003] The specific steps of photoresist coating include placing the silicon wafer in a coating and developing machine, and spraying photoresist onto the surface of the silicon wafer through the photoresist nozzle of the coating and developing machine; the photoresist colloid contains air, which causes bubbles to be generated during the coating process, resulting in uneven coating, which in turn affects the coating quality.

[0004] Therefore, the utility model provides a glue coating mechanism utilizing vibration and needle bar defoaming and a glue coating developing machine including the glue coating mechanism. Utility Model Content

[0025] Reference Figure 1-Figure 4 As shown, this embodiment provides a specific implementation method for a glue coating mechanism, including a glue coating bin 1 and a workbench, wherein the glue coating bin 1 is in a truncated cone shape and is set on the workbench.

[0026] The glue coating chamber 1 comprises a glue feeding pipe 81, a glue coating head 84, and an operating chamber 83. The glue feeding pipes 81 are provided with two glue feeding pipes 81, and are symmetrically distributed on both sides of the glue coating head 84. The glue coating head 84 is suspended in the center of the bottom of the operating chamber 83. The operating chamber 83 is a truncated cone-shaped chamber.

[0027] The glue coating chamber 1 further comprises a transfer chamber 82, which is located at the top middle position of the working chamber 83, and is communicated with two glue feeding pipes 81.

[0028] The transfer bin 82 is a hemispherical cavity with an opening facing upward, and the top is connected to the inner wall of the glue coating bin 1 to form a closed loop.

[0029] The glue inlet pipe 81 transports the glue liquid from the glue barrel storage tank 3 to the glue storage tank 00, and transfers it to the glue coating head 84 through the infusion pipe 93 at the bottom center of the glue storage tank 00, so that it can be used for glue coating operations.

[0030] The transfer bin 82 includes a glue storage tank 00 and a bubble removal end 01. The bubble removal end 01 is suspended in the middle position above the glue storage tank 00. The glue storage tank 00 is connected to two glue inlet pipes 81.

[0031] The bottom of the glue storage tank 00 is flat and the opening is upward. The glue storage tank 00 supplies glue to the glue coating head 84 to facilitate its operation.

[0032] In one specific embodiment, the side surface of the glue storage groove 00 is a curved surface, which is not easy to retain the colloid, allowing the colloid to slide downward smoothly, the colloid flow is more concentrated, and the glue discharge is more stable.

[0033] The defoaming end 01 includes a telescopic end 02, a heating plate 03 and a needle rod 04. The needle rod 04 is installed on a fixed plate by disassembly. The heating plate 03 is fixedly installed on the other side of the fixed plate, and the fixed plate is connected to the telescopic end 02.

[0034] Furthermore, the telescopic end 02 is an electric telescopic rod or an electric cylinder, as long as it can drive the needle rod 04 to move up and down.

[0035] The needle bar 04 of the utility model is heated by the heating plate 03, so that it has a certain temperature. The telescopic end 02 drives the fixed plate to move up and down, so that the needle bar 04 on the fixed plate is inserted into the liquid surface layer of the glue during the descending process to eliminate the bubbles in the glue.

[0036] In one specific embodiment, the needle rod 04 includes a horizontally arranged main board and a plurality of heat-conducting needles embedded in the bottom surface of the main board. These heat-conducting needles are linearly distributed, including but not limited to array distribution and circular radial distribution. A large number of densely distributed heat-conducting needles are moved downward to puncture and eliminate bubbles in the colloid.

[0037] Furthermore, the thermal conductive needle is made of a material with high thermal conductivity, including but not limited to metal and alloy.

[0038] A liquid infusion tube 93 is installed at the center of the bottom of the glue storage tank 00, and a striking block 91 is provided on the outer wall of the bottom of the glue storage tank 00. The striking block 91 is mechanically connected to the telescopic rod 92.

[0039] The bubbles in the glue liquid entering the glue storage tank 00 are driven by the telescopic rod 92 to drive the striking block 91 to act on the bottom of the glue storage tank 00, causing the glue storage tank 00 to vibrate, so that the bubbles in the glue liquid in the tank move upward under the action of the vibration, effectively preventing the bubbles from directly entering the infusion tube 93, thereby improving the quality of the glue coating operation.

[0040] A glue coating and developing machine comprises the above-mentioned glue coating mechanism, and further comprises a machine body, a glue barrel storage slot, and a display screen.
