Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing, in particular to a rotary glue wiping mechanism. Background Art

[0002] With the continuous development of technology, the dispensing process is more and more widely used in 3C and semiconductor fields, and the requirements for the automation of the dispensing process are getting higher and higher. Glue hanging on the needle or nozzle is a difficulty in the dispensing industry, which cannot be completely avoided at present. The contact-type glue wiping method before printing is used to deal with the residual glue on the needle. However, due to the limitations of the current glue wiping method, the residual glue cannot be completely cleaned, and long-term operation affects the yield.

[0003] At present, the common methods of wiping glue in the field of dispensing technology include wiping on the plane or wiping on both sides. Both of these methods have cleaning dead corners and cannot effectively remove residual glue from the nozzle. As the equipment operating time continues to increase, the printing yield will be affected. Therefore, designing a new and efficient wiping mechanism has important research significance.

[0004] The "glue wiping device" is disclosed in Chinese patent documents, and its announcement number is CN219226305U. The glue wiping platform of the utility model is movably arranged on the base. By adopting a floating glue wiping platform structure, while protecting the glue dispensing structure, the glue wiping tape and the glue dispensing structure are closely applied, so that there is no dead angle for wiping the glue, and a better glue wiping effect can be achieved. The glue wiping device can realize automatic wiping of components in photovoltaic modules through the coordinated arrangement of unwinding mechanism, glue wiping mechanism, winding mechanism, etc., and can be used in the photovoltaic industry. No manual wiping is required, and the glue wiping effect can be guaranteed. It has a simple structure and a high degree of automation, which is conducive to improving production efficiency and saving labor costs. However, this patent is only applicable to wiping the bottom plane, and cannot be applied to wiping the side of the needle or nozzle. In addition, it has a complex structure and high production cost, which is not conducive to industrialization. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of the utility model is to provide a rotary glue erasing mechanism to solve the problem that the existing glue erasing methods have cleaning dead corners and cannot effectively remove the residual glue on the side of the nozzle, which will affect the printing yield as the equipment operating time continues to increase.

[0006] To achieve the above-mentioned purpose and other related purposes, the utility model is implemented by including the following technical solutions.

[0007] The utility model provides a rotary glue erasing mechanism, comprising a glue erasing mechanism and a rotating mechanism for driving the glue erasing mechanism to rotate, wherein the glue erasing mechanism comprises an unwinding mechanism, an eraser tape, an eraser head module for 360° erase, and a rewinding mechanism, wherein the eraser tape is sequentially wound on the unwinding mechanism, the eraser head module, and the rewinding mechanism, wherein the unwinding mechanism is used to provide a feeding power for the eraser tape, and the eraser tape located in the eraser head module area is used to wipe the glue dispensing head; and the rewinding mechanism is used to provide a rewinding power for the wiped eraser tape.

[0008] Preferably, a flexible liquid absorption block is provided between the erasing head module and the erasing tape. On the one hand, the flexible liquid absorption block is convenient for absorbing the glue absorbed by the erasing tape to prevent the glue from falling during the wiping process and keep the device clean; on the other hand, it can wrap the dispensing needle or nozzle during wiping to achieve 360° automatic and non-destructive cleaning without dead ends.

[0009] Preferably, the rubber erasing head module is a planar rubber erasing head module or a clamping rubber erasing head module.

[0010] In the above technical scheme of the present application, the nozzle residual glue is cleaned 360° without dead angles through the rotating mechanism. After wiping is completed, the winding mechanism can realize the automatic rotation and winding of the wiping tape to replace the dirty wiping tape. The operation mode of the utility model is as follows: before the equipment prints, the dispensing needle or nozzle is moved to the top of the wiping dispensing head, and dropped to the Z-axis height position set in advance, so that the dispensing needle or nozzle is lowered to contact the wiping dispensing head, and the rotating mechanism starts to rotate, driving the wiping mechanism to rotate so that the wiping tape completes the wiping of the dispensing needle or nozzle without dead angles (simulating manual wiping action). After wiping is completed, the Z axis is lifted to a safe height, and the winding mechanism rotates to rewind the dirty wiping tape, completing the 360° automatic cleaning of the dispensing needle or nozzle without dead angles. The flat-type wiping head module or the clamping-type wiping head module can be switched at will according to the wiping requirements.

[0011] Preferably, the planar eraser head module is provided with an eraser platform, and the eraser tape located in the planar eraser head module area is in contact with the eraser platform.

[0012] Preferably, the clamping type eraser head module includes an electric clamp and an eraser tape limiting shaft, the electric clamp includes a first clamp and a second clamp that are arranged opposite to each other, a clamping space is formed between the first clamp and the second clamp, and the eraser tape limiting shaft is arranged in the clamping space; the eraser tape in the clamping space is limited by the eraser tape limiting shaft and then fits with the surfaces of the first clamp and the second clamp.

The flexible liquid absorbent blocks are convenient for absorbing the glue absorbed by the wiping tape to prevent the glue from falling during the wiping process and keep the device clean. On the other hand, the relatively arranged flexible liquid absorbent blocks can wrap the glue dispensing needle or nozzle during wiping to achieve 360° automatic cleaning without dead ends.

[0014] Preferably, the rotating mechanism includes a rotating motor, the rotating motor is provided with a rotating shaft, the rotating shaft is sequentially connected with an electric rotating connector and a coupling, and the eraser mechanism is connected to the coupling. Since the unwinding mechanism, the winding mechanism, the electric clamp and other components need to be powered by an external power supply, during the electrical design process, when the above-mentioned mechanical part rotates 360 degrees without limit and continuously, the wire needs to be connected to the rotating part, which will encounter the problem of wire entanglement. The present application adopts an electric rotating connector to transmit the rotating connection of power and signals, which can avoid the entanglement of wires and realize the rotating connection of the power supply of the above-mentioned mechanisms. The coupling facilitates the transmission connection.

[0022] (1) A 360° erasing head module is used, combined with a rotating mechanism to achieve 360° cleaning of residual adhesive on the nozzle without dead angles. After wiping is completed, the winding mechanism can realize automatic rotation and winding of the erasing tape to replace the dirty erasing tape;
