Description

Technical Field

[0001] The invention relates to the technical field of glue outlet cleaning, in particular to a glue erasing device with glue erasing claws. Background Art

[0002] With the rapid development of the electronics industry, the bonding and potting technologies in the electronic packaging industry have also been rapidly improved. As the core of dispensing technology, contact dispensing has also been rapidly developed. As electronic products require high-precision and pollution-free dispensing, higher requirements are placed on contact dispensing.

[0003] Contact dispensing is the process of applying glue to products through dispensing needles, mixing tubes or self-made dispensing pipes. However, in actual work, the following problems often occur:

[0004] 1. After the dispensing valve is closed, the glue outlet (including the dispensing needle, mixing tube or self-made glue outlet pipe) often has a drawing phenomenon, resulting in residual glue at the glue outlet. Excessive residue will affect the subsequent dispensing effect.

[0005] 2. After the dispensing valve is closed, glue dripping will occur at the glue outlet due to the slow release of glue pressure. Wait until the glue pressure is completely released before the next dispensing. The dripping glue will contaminate the product.

[0006] Due to the relationship between the eraser position and angle, the existing eraser still leaves glue residue after erase, resulting in poor cleaning effect. Summary of the Invention

[0007] In order to solve the problem of glue residue at the glue outlet in the prior art, the present invention provides a glue erasing device with glue erasing claws having good cleaning effect.

[0008] The technical solution adopted by the present invention to solve its technical problem is:

[0009] A glue-erasing device with glue-erasing jaws includes a base positioned below the glue-dispensing needle of a glue-dispensing machine. Several glue-erasing jaws are evenly distributed circumferentially on the base. The glue-erasing jaws comprise a base, a glue-erasing tape, and a conveying mechanism mounted on the base for conveying the glue-erasing tape to the glue-dispensing needle. The conveying mechanism includes a glue-erasing pulley assembly and a raw material tray for supplying the glue-erasing tape. During glue-erasing, the glue-erasing pulley assembly, wrapped with the glue-erasing tape, encircles and wraps the glue-dispensing needle. The number of glue-erasing jaws can be adjusted as needed.

[0010] Furthermore, the base is also provided with an adjustment mechanism for adjusting the conveying mechanism in the direction of approaching and moving away from the dispensing needle. By providing the adjustment mechanism, the size of the circular area formed by the glue-erasing clamping claws can be adjusted, so that different needles can be accommodated.

[0011] Furthermore, the adjustment mechanism includes a first connecting rod, a second connecting rod and a third connecting rod, the first end of the first connecting rod is hinged on the base, the second end of the first connecting rod is hinged on the third connecting rod, the first end of the second connecting rod is hinged on the base, the second end of the second connecting rod is hinged on the third connecting rod, the first connecting rod or the second connecting rod is connected to a second motor, and the raw material disk and the wiping tape wheel assembly are installed on the third connecting rod.

[0012] Furthermore, the base is mounted on the base via a rotating mechanism. When encountering glue that cures quickly, it tends to solidify at the glue outlet. The glue-erasing jaws can rotate and simultaneously move up and down in conjunction with the glue outlet to wipe away any remaining glue. Furthermore, for glues made from certain materials, the glue-erasing tape on the raw material tray can be attached with a glue remover, making it easier to remove glue from the needle tip.

[0013] Furthermore, the rotating mechanism includes a driving gear and a driven gear rotatably arranged on the base and meshing with each other, the driving gear is connected to a driving motor, and the base is fixed on the driven gear.

[0014] Furthermore, a material receiving tray is installed on the base, and the material receiving tray is connected to a third motor that drives the tray to rotate.

[0015] Furthermore, a glue sealing device is fixed on the driven gear just below the glue dispensing needle, and the glue sealing device is a waste glue tank or a needle sealing tank.

[0016] Furthermore, the rubbing belt pulley assembly includes a driving pulley, a driven pulley and a conveyor belt, and the rubbing belt is wound around the outside of the conveyor belt.

[0017] Furthermore, the material of the conveyor belt is a flexible material, and preferably, the conveyor belt is a silicone belt.

[0018] Furthermore, the driving pulley is connected to a first motor for driving the driving pulley to rotate. The speed of the first motor is adjustable, so that the rubbing speed is adjustable.

[0019] Beneficial effects:

[0020] (1) The patented eraser gripper is designed to resemble a cotton peach structure, which can adapt to a variety of glue outlets, various specifications of plastic steel dispensing needles, TT dispensing needles, mixing tubes and self-made glue outlets;

[0021] (2) The patented eraser device can be installed at the desired location through the base, is easy to disassemble, and has strong versatility;

[0022] (3) The conveyor belt is made of soft silicone and wrapped with wiping tape to protect the dispensing needle from deformation during the wiping process;

[0023] (4) The eraser is mounted on a rotatable gear. When encountering glue with a fast curing speed, it is easy to solidify at the glue outlet. The gear can be rotated to rotate the eraser to erase the needle. At the same time, the glue outlet moves up and down to wipe off the residual glue.

[0024] (5) A waste glue tank or a sealing needle tank can be placed under the glue outlet. During the non-dispensing period, the glue outlet can be immersed in the silicone oil box to prevent the glue from solidifying. Some glues need to be discharged regularly during dispensing. The silicone oil box can be replaced with a waste glue tank. After the glue is discharged, wipe the glue outlet at the same time and continue dispensing. BRIEF DESCRIPTION OF THE DRAWINGS
