Description

Technical Field

[0001] The utility model relates to the field of glue dispensing equipment, in particular to a glue wiping mechanism with a double-wiping wheel glue dispensing needle. Background Art

[0002] Automatic dispensing equipment is an automated equipment that can automatically dispense glue to the designated position of the product. After the dispensing needle dispenses glue, there will be residual glue overflowing on the white surface, so the dispensing needle needs to be wiped during the dispensing process.

[0003] For the wiping process of the dispensing needle, the existing wiping mechanism with the publication number CN115090464A includes a mounting seat; a support assembly, including a plurality of support parts arranged on the mounting seat and spaced apart, at least some of the support parts are detachably mounted; an wiping assembly, including an wiping tape that is optionally wound around the plurality of support parts, the wiping tape being movably arranged along its length, a section of the wiping tape forming a width-adjustable wiping groove and / or a flat wiping section between some of the support parts; and a driving assembly for driving the wiping tape to move.

[0004] The existing glue wiping mechanism adopts a single dust-free cloth roll to be retracted and released, and the V-angle of the dust-free cloth is used in conjunction with the clamping cylinder to perform glue wiping. The existing glue wiping mechanism will cause the dust-free cloth to waste a section of clean dust-free cloth each time it wipes the glue, resulting in frequent replacement of the dust-free cloth and increased equipment operating costs. At the same time, the glue wiped off the surface of the dust-free cloth may contact the first support part, causing the glue to be retained there. Utility Model Content

[0007] Furthermore, the chuck is provided with an arc-shaped groove, the material of the chuck is rubber, the base is provided with a clearance groove, and the chuck is located in the clearance groove.

[0008] Furthermore, laser sensors are provided on the base at the diameters of the receiving wheel and the discharging wheel of each dust-free cloth receiving and discharging assembly.

[0009] Furthermore, both the receiving wheel and the discharging wheel can be detachably connected with a limit plate.

[0010] Furthermore, the diameters at both ends of the guide wheel are larger than the diameter of the middle section.

[0011] The beneficial effects of the utility model are: through the coordinated use of the clamping cylinder, the chuck, the dust-free cloth retracting and releasing assembly, the limit plate, and the laser sensor, the installation and maintenance of the dust-free cloth are facilitated, the utilization rate of the dust-free cloth is improved, the replacement frequency of the dust-free cloth is reduced, and the glue will not contact the guide wheel.

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] refer to Figures 1-4The double-rubber wheel dispensing needle glue wiping mechanism shown in the figure includes a base 1, a strip groove 101 is provided in the middle of the base 1, and a clamping cylinder 2 is fixedly connected to the lower part of the strip groove 101 by a screw. The strip groove 101 is provided to adjust the installation position of the clamping cylinder 2 to adapt to the glue wiping process of different dispensing mechanisms. The clamping jaws of the clamping jaw cylinder 2 are fixedly connected to the chuck 201. The two sides of the base 1 are mirror-imaged with dust-free cloth retracting components, and the dust-free cloth retracting components include The motor 301, the receiving wheel 302, the unloading wheel 303, the guide wheel group 304 and the dust-free cloth roll 305, the guide wheel group 304 includes multiple guide wheels, and the multiple guide wheels are distributed in a trapezoidal shape on the base 1. The receiving wheel 302, the unloading wheel 303 and the guide wheels are all rotatably connected to the base 1, the rotating shaft of the motor 301 is fixedly connected to the receiving wheel 302, and the two clamping jaws of the clamping cylinder 2 are respectively located between the guide wheels of the two guide wheel groups 304.

[0019] The chuck 201 is provided with an arc groove, which can make way for the needle. The chuck 201 is made of rubber, and the base 1 is provided with a make way groove. The chuck 201 is located in the make way groove, which can make way for the jaws of the chuck 201.

[0020] The base 1 is provided with a laser sensor 5 on the diameter of the receiving wheel 302 and the discharging wheel 303 of each dust-free cloth receiving and placing assembly. The laser sensor 5 is used to detect whether the dust-free cloth in the dust-free cloth receiving and placing assembly has been used up.

[0021] The receiving wheel 302 and the discharging wheel 303 can be detachably connected to the limiting disk 4, which can prevent the dust-free cloth roll 305 from running away during the receiving and discharging process.

[0022] The diameters of the two ends of the guide wheel are larger than the diameter of the middle section, thereby achieving vertical positioning of the dust-free cloth roll.

[0023] The working principle of the present invention is as follows: when in use, the dust-free cloth roll 304 is placed on the unwinding wheel 301, and is guided backward by the guide wheel group 304 and fixed on the receiving wheel 302 for rewinding. The dust-free cloths of the two dust-free cloth rewinding assemblies are clamped at a V angle at the clamping cylinder 2. When wiping glue, the dispensing needle of the dispensing machine moves between the two clamping jaws of the clamping cylinder 2. At this time, the dispensing needle is located between the two dust-free cloths, and the clamping cylinder 2 drives the clamping head 201 to approach each other so that the two dust-free cloths are close to the needles. The dispensing needle is pulled out when the clamping cylinder is clamped, and the glue wiping process is completed by the friction between the dust-free cloth and the needle. After that, the clamping cylinder is loosened, and the motors of the two dust-free cloth retracting assemblies drive the receiving wheel 302 to rotate and rewind the dust-free cloth. The dust-free cloth that has been wiped with glue can be pushed forward from the glue wiping station.

[0024] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be understood to be within the scope of protection of the present invention.
