Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and in particular to a glue-wiping mechanism for a dispensing machine. Background Technology

[0002] With my country's rapid development, the drawbacks of manual labor have become incompatible with current production needs. Manual labor requires highly experienced operators and is only suitable for small-batch production. When mass production is needed, it not only affects production capacity but also makes it difficult to guarantee product quality. The replacement of manual labor with automated production is an inevitable trend in the industry.

[0003] For delicate small parts, manual dispensing is inefficient and it is difficult to ensure the consistency of the dispensing amount, making it difficult to control the quality. After the product is dispensing, the residual glue on the dispensing head needs to be wiped off to avoid the residual glue affecting the next dispensing. After each dispensing, the needle of the syringe needs to be wiped with a dispensing wiping mechanism. The current dispensing wiping mechanism has low wiping efficiency and cannot clean the dispensing needle well. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a glue-wiping mechanism for a dispensing machine, which facilitates self-service dispensing and automatic glue wiping after dispensing.

[0005] The technical solution of this utility model is as follows: a glue-wiping mechanism for a dispensing machine, including a frame, a movable module mounted on the frame, a dispensing component mounted on the output end of the movable module, and a glue-wiping component correspondingly mounted below the dispensing component. The glue-wiping component includes a clamping and wiping structure and a flat wiping structure arranged in parallel. The flat wiping structure includes a mounting plate, a transmission motor fixed on the mounting plate, a material reel assembly connected to the output end of the transmission motor, a pulley assembly, and a glue-wiping conveyor belt. The glue-wiping conveyor belt is wound around the pulley assembly through the material reel assembly. The pulley assembly includes a first pulley and a second pulley arranged in parallel. The glue-wiping conveyor belt between the first pulley and the second pulley is horizontally conveyed. The clamping and wiping structure includes a pneumatic clamp fixed on the mounting plate, a clamping block seat connected to the output end of the pneumatic clamp, and a clamping and wiping wheel rotatably connected to the clamping block seat. The clamping and wiping wheel is horizontally arranged outside the first pulley.

[0006] As can be seen from the above scheme, the adhesive wiping assembly is used to wipe adhesive below the dispensing assembly, thereby avoiding the adhesive from affecting the next dispensing. The material tape reel is used to receive and release the material. The adhesive wiping conveyor belt is used to wipe the bottom of the dispensing assembly by conveying and translating. The clamping and wiping roller and the clamping block seat are used for clamping and wiping. The adhesive is wiped on the dispensing assembly through the clamping and wiping structure and the flat wiping structure.

[0007] The frame is equipped with a detection component parallel to the dispensing assembly. The moving module includes an X-axis moving unit, a Y-axis moving unit slidably fitted on the X-axis moving unit, and a lifting mounting base slidably fitted on the Y-axis moving unit. The dispensing assembly is connected to the lifting mounting base, and the detection component is slidably connected to the Y-axis moving unit. Therefore, the moving module achieves adjustment in three axes through the X-axis moving unit, the Y-axis moving unit, and the lifting mounting base.

[0008] The dispensing assembly includes a connector, a glue reservoir mounted on the connector, a glue valve, and a dispensing head. The glue valve is connected to the glue reservoir, and the dispensing head is connected to the bottom end of the glue valve. The dispensing head is positioned above the glue-applying conveyor belt. Therefore, the glue reservoir is used to store glue, and the dispensing head is used to dispense the glue.

[0009] The detection assembly includes a detection base, a detection camera mounted on the detection base, and a light source. The light source is positioned below the detection camera, and the detection base is slidably engaged with the frame.

[0010] The wiping structure also includes a gripper cylinder mounted on the mounting plate. Two sets of gripping blocks on the output end of the gripper cylinder are respectively connected to the first pulley and the second pulley via connecting blocks. Therefore, the gripper cylinder is used to adjust the distance between the first pulley and the second pulley, thereby adjusting the length of the adhesive-wiping conveyor belt of the flat wiping structure.

[0011] The pulley assembly also includes guide wheels, which slide in conjunction with guide rails on the mounting plate via sliders. The guide rails are vertically mounted on the mounting plate. Therefore, the guide wheels can be adjusted up and down on the mounting plate via the guide rails, facilitating tension adjustment of the adhesive-applying conveyor belt. Attached Figure Description

[0016] like Figures 1 to 3 As shown, this utility model is a glue-wiping mechanism for a dispensing machine, including a frame 1, a movable module 2 mounted on the frame 1, a dispensing assembly 3 mounted on the output end of the movable module 2, and a glue-wiping assembly 4 correspondingly mounted below the dispensing assembly 3. The glue-wiping assembly 4 includes a clamping structure and a flat wiping structure arranged side by side. The flat wiping structure includes a mounting plate 40, a conveyor motor 42 fixed on the mounting plate 40, a tape reel assembly 41 connected to the output end of the conveyor motor 42, a pulley assembly, and a glue-wiping conveyor belt 43. The adhesive-applying conveyor belt 43 is wound around the pulley group via the material reel assembly 41. The pulley group includes a first pulley 44 and a second pulley 45 arranged side by side. The adhesive-applying conveyor belt 43 between the first pulley 44 and the second pulley 45 provides horizontal transport. The clamping and wiping structure includes a pneumatic clamp 46 fixed on the mounting plate 40, a clamping block seat 47 connected to the output end of the pneumatic clamp 46, and a clamping and wiping wheel 48 rotatably connected to the clamping block seat 47. The clamping and wiping wheel 48 is horizontally arranged outside the first pulley 44. In this embodiment, a fixture is arranged directly below the dispensing assembly, and a magnetic core product is installed inside the fixture. The adhesive-applying assembly 4 is arranged in front of the fixture. After the dispensing assembly 3 is driven by the moving module 2 to dispense adhesive onto the magnetic core product on the fixture, the moving module 2 drives the dispensing assembly 3 to move above the corresponding part of the adhesive-applying assembly 4 to wipe the adhesive from the dispensing head, avoiding residual adhesive from affecting the next dispensing.

[0017] The frame 1 is provided with a detection component 5 parallel to the dispensing assembly 3. The moving module 2 includes an X-axis moving unit 21, a Y-axis moving unit 22 slidably engaged on the X-axis moving unit 21, and a lifting mounting base 23 slidably engaged on the Y-axis moving unit 22. The dispensing assembly 3 is connected to the lifting mounting base 23, and the detection component 5 is slidably connected to the Y-axis moving unit 22.

[0018] The dispensing assembly 3 includes a connector 31, a glue reservoir 32 disposed on the connector 31, a glue valve 33, and a dispensing head 34. The glue valve 33 is connected to the glue reservoir 32, and the dispensing head 34 is connected to the bottom end of the glue valve 33. The dispensing head 34 is correspondingly disposed above the glue-wiping conveyor belt 43.

[0019] The detection component 5 includes a detection base 51, a detection camera 52 disposed on the detection base 51, and a light source 53. The light source 53 is disposed below the detection camera 52. The detection base 51 is slidably engaged with the frame 1.

[0020] The clamping structure also includes a gripper cylinder 491 disposed on the mounting plate 40. Two sets of gripping blocks on the output end of the gripper cylinder 491 are respectively connected to the first pulley 44 and the second pulley 45 through connecting blocks.

[0021] The pulley assembly also includes a guide wheel 492, which slides with a guide rail 401 on the mounting plate 40 via a slider. The guide rail 401 is vertically arranged on the mounting plate 40.

[0022] The working process of this utility model is as follows: the moving module 2 drives the dispensing assembly 3 to move downward, and the dispensing head 34 dispenses glue to the magnetic core product in the fixture directly below. After a single dispensing is completed, the Y-axis moving unit 22 drives the dispensing assembly 3 to move forward, the conveyor motor 42 drives the material belt reel 41 to rotate, and the glue-wiping conveyor belt 43 between the first pulley 44 and the second pulley 45 moves horizontally to wipe away the residual glue at the bottom of the dispensing head 34. The dispensing head 34 moves down between the clamping and wiping wheel 48 and the first pulley 44. The pneumatic clamp 46 drives the clamping and wiping wheel 48 on the clamping block seat 47 to move closer to the first pulley 44 to clamp the dispensing head 34. The glue-wiping conveyor 43 moves to wipe away the residual glue. The pneumatic clamp 46 drives the clamping and wiping wheel 48 to move away from the first pulley 44 to release the dispensing head 34. The dispensing head 34 is reset and the next dispensing process begins.

[0023] Finally, it should be emphasized that the above description is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
