Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a non-stop material changing and wiping mechanism. Background Technology

[0002] In modern industrial production, especially in fields such as electronic packaging and precision assembly, automated dispensing machines are widely used. Dispensing machines precisely apply adhesive through their nozzles, and the cleanliness of the nozzles directly affects the accuracy, consistency, and quality of the final product. If there is cured adhesive or contaminants remaining in the nozzles, it will lead to problems such as poor dispensing, stringing, and clogging, which will seriously affect the production yield.

[0003] To ensure dispensing quality, existing dispensing equipment usually integrates an automatic cleaning mechanism. These mechanisms mostly use roll-shaped cleaning cloths or cleaning paper as consumables. During the intervals between dispensing machine operations, a clean cleaning cloth is driven by a mechanical device to move under the nozzle and wipe the nozzle to remove residual adhesive.

[0004] However, as a consumable, the roll of cleaning cloth will be consumed and eventually run out during use. In the existing technology, when the cleaning cloth is exhausted, the entire dispensing equipment usually needs to be stopped, and then the operator needs to manually open the equipment protective cover and replace it with a new roll of material. The entire material replacement process will cause the production line to be interrupted, reducing the effective working time of the equipment and the overall production efficiency.

[0005] Therefore, this utility model proposes a non-stop material changing and wiping mechanism to overcome the shortcomings of the prior art. Summary of the Invention

[0006] In view of the problems in the existing material changing and wiping mechanisms, such as the need to stop the equipment and interrupt production when changing cleaning consumables, and the poor cleaning effect of a single cleaning medium, this utility model aims to provide a material changing and wiping mechanism with an improved structure that can effectively solve the above problems without stopping the machine.

[0007] This utility model provides a non-stop material changing and wiping mechanism, including: a base plate for the wiping mechanism, a cloth conveyor assembly, a cleaning assembly, a dust-free cloth, and a photoelectric switch.

[0008] The conveyor belt assembly includes a feeding tray and a receiving tray rotatably connected to the base plate of the adhesive wiping mechanism, and a stepper motor fixedly connected to the base plate of the adhesive wiping mechanism and driven by the receiving tray. The cleaning assembly includes a cleaning cotton mounting plate fixedly connected to the base plate of the adhesive wiping mechanism, and a cleaning cotton body is mounted on the cleaning cotton mounting plate.

[0009] The lint-free cloth is wound between the feeding tray and the receiving tray, and driven by the stepper motor, its movement path is set to pass through and cover the surface of the cleaning cotton body, thus forming a composite cleaning surface together with the cleaning cotton body. The photoelectric switch is set on the bottom plate of the wiping mechanism, and its position is set to monitor the remaining roll diameter of the lint-free cloth on the feeding tray.

[0010] Preferably, the non-stop material changing and wiping mechanism further includes at least one driven wheel, which is rotatably mounted on the base plate of the adhesive wiping mechanism, and the movement path of the lint-free cloth between the feeding tray and the composite cleaning surface is configured to pass around the driven wheel.

[0011] Preferably, the axis of the driven wheel is parallel to the axis of the feeding tray, and the driven wheel is used to tension the cleanroom cloth.

[0012] Preferably, the non-stop material changing and wiping mechanism further includes a photoelectric sensor, which is mounted on the base plate of the adhesive wiping mechanism, and the detection area of ​​the photoelectric sensor faces the movement path of the cleanroom cloth in the conveyor belt assembly.

[0013] Preferably, the detection optical path of the photoelectric switch is configured to span the outer edge of the roll of the cleanroom cloth wound on the feeding tray.

[0014] Preferably, the adhesive cotton mounting plate and the adhesive wiping mechanism base plate are connected by adjustable fasteners to adjust the height of the adhesive cotton body relative to the adhesive wiping mechanism base plate.

[0015] Preferably, the adhesive cotton body is a long strip-shaped block and is detachably installed on the adhesive cotton mounting plate.

[0016] Preferably, the cleaning component is located between the feeding tray and the receiving tray, and the lint-free cloth passes sequentially through the feeding tray, the composite cleaning surface, and is wound up by the receiving tray.

[0017] This utility model has the following beneficial effects: This invention solves the problem of production interruption caused by the need to stop equipment operation when changing consumables in the prior art by setting a photoelectric switch for monitoring the remaining amount of cleaning cloth. It can provide early warning and achieve material change without stopping the machine, thereby improving the continuity of production and overall efficiency.

[0018] This invention solves the problem in the prior art that a single cleaning medium cannot effectively remove both sticky adhesive and fine dust simultaneously by layering the cleaning cotton body and the lint-free cloth to form a composite cleaning surface. It achieves a dual and enhanced cleaning effect and ensures the cleanliness of the nozzle.

[0019] This invention solves the problem of wrinkling or deviation of the cleaning cloth due to unstable tension during transmission by setting a driven wheel to tension the conveying path of the clean cloth, ensuring that the cleaning surface is always flat and the contact is stable and reliable, thus improving the consistency of cleaning quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 2 This utility model provides a non-stop material replacement wiping mechanism, which aims to solve the problems in the prior art where the cleaning device of the dispensing machine must stop production when changing cleaning consumables, and the cleaning is not thorough with a single cleaning medium.

[0024] like Figure 1 and Figure 2As shown, the non-stop material changing and wiping mechanism includes a wiping mechanism base plate 5, and a cloth conveying assembly and a cleaning assembly mounted on the wiping mechanism base plate 5. The wiping mechanism base plate 5 provides a modular mounting base for the entire device. The cloth conveying assembly and the cleaning assembly work together to achieve automated cleaning. Specifically, the cloth conveying assembly includes a feeding tray 6 and a receiving tray 10 rotatably connected to the wiping mechanism base plate 5. The two ends of the cleanroom cloth 8 are respectively wound around the feeding tray 6 and the receiving tray 10. The cloth conveying assembly also includes a stepper motor 9 fixedly connected to the wiping mechanism base plate 5. The stepper motor 9 drives the receiving tray 10 to provide winding power to the receiving tray 10, thereby driving the cleanroom cloth 8 to move along a preset path for cleaning. The component includes a cleaning cotton mounting plate 3 fixedly connected to the base plate 5 of the wiping mechanism. A cleaning cotton body 7 is mounted on the cleaning cotton mounting plate 3. As the lint-free cloth 8 moves from the feeding tray 6 to the receiving tray 10, its movement path is set to pass through and cover the surface of the cleaning cotton body 7. The lint-free cloth 8 and the cleaning cotton body 7 together form a composite cleaning surface for wiping. This composite cleaning surface first uses the cleaning cotton body 7 to remove large pieces of adhesive residue, and then uses the lint-free cloth 8 for fine wiping. In order to achieve material replacement without stopping the machine, a photoelectric switch 1 is also provided on the base plate 5 of the wiping mechanism. The position of the photoelectric switch 1 is set to monitor the remaining roll diameter of the lint-free cloth 8 on the feeding tray 6. When the roll diameter is less than a preset value, a signal is output to provide an early warning for replacing consumables.

[0025] To further optimize the stability of the cleanroom cloth 8 during the conveying process, the non-stop material changing wiping mechanism also adds at least one driven wheel 2 on the path of the cloth conveying assembly. Furthermore, the driven wheel 2 forms a specific position and cooperation relationship with the adhesive wiping mechanism base plate 5 and the cleanroom cloth 8 to ensure that the cleanroom cloth 8 remains stable and taut during the cleaning operation.

[0026] Please refer to Figure 1 The driven wheel 2 is rotatably mounted on the base plate 5 of the adhesive wiping mechanism. Specifically, its mounting position is set between the feeding tray 6 and the aforementioned composite cleaning surface. The axis of the driven wheel 2 is parallel to the rotation axis of the feeding tray 6. After the cleanroom cloth 8 is led out from the feeding tray 6, its movement path is set to go around the outer circumference of the driven wheel 2 and then travel to the composite cleaning surface. The driven wheel 2 is used as a guide and tension wheel here. By changing the travel path of the cleanroom cloth 8, a constant tension is applied to the cleanroom cloth 8. This tensioning structure ensures that the surface of the cleanroom cloth 8 delivered to the composite cleaning surface is flat and wrinkle-free, thereby ensuring the uniformity and reliability of the wiping effect and effectively preventing the cloth belt from deviating during high-speed movement.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to achieve comprehensive monitoring of the operating status of the mechanism, a photoelectric sensor 4 is also provided on the base plate 5 of the adhesive wiping mechanism. The detection area of ​​the photoelectric sensor 4 faces the movement path of the cleanroom cloth 8 in the conveyor belt assembly, so as to monitor the integrity of the cleanroom cloth 8 or whether there is any abnormal state such as deviation in real time. At the same time, the setting method of the photoelectric switch 1 is refined. Its detection light path is set to cross the outer edge of the roll of cleanroom cloth 8 wound on the feeding tray 6. The remaining roll diameter of the cleanroom cloth 8 is determined by whether the light path is blocked by the wound cloth.

[0028] In a preferred embodiment, to accommodate dispensing nozzles of different heights or types, the adhesive cotton mounting plate 3 and the adhesive wiping mechanism base plate 5 are connected by adjustable fasteners. For example, the adhesive cotton mounting plate 3 is fastened to the adhesive wiping mechanism base plate 5 by bolts passing through the elongated through holes on the adhesive cotton mounting plate 3. This structure allows the adhesive cotton mounting plate 3 to float up and down or adjust its height within a certain range, thereby changing the pressing contact force of the adhesive cotton body 7.

[0029] In a preferred embodiment, the cleaning cotton body 7 is a long strip-shaped block that is detachably installed on the cleaning cotton mounting plate 3. For example, the cleaning cotton mounting plate 3 is provided with a dovetail groove or a snap-fit ​​structure, and the corresponding part of the cleaning cotton body 7 is provided with a matching structure. It is installed and fixed by sliding or snapping. This method facilitates quick replacement when the cleaning cotton body 7 is worn or needs to be replaced with different materials.

[0030] Furthermore, to ensure the smooth and stable conveying path of the cloth belt, the layout of the entire mechanism is optimized. The cleaning component is fixed on the bottom plate 5 of the adhesive wiping mechanism between the feeding tray 6 and the receiving tray 10, so that the clean cloth 8 can form a clear motion flow line, that is, it is led out from the feeding tray 6 in sequence, passes around the driven wheel 2 used for tensioning, passes smoothly over the composite cleaning surface, and is finally evenly wound up by the receiving tray 10. The axis of the driven wheel 2 is parallel to the axis of the feeding tray 6 to ensure that the cloth belt is evenly stressed during the conveying process and to prevent twisting.

[0031] The working principle of this non-stop material changing and wiping mechanism is as follows: In use, the entire roll of cleanroom cloth 8 is installed on the feeding tray 6. One end of the cloth is wrapped around the driven wheel 2 and covers the surface of the cleanroom cloth body 7, which is fixed on the cleanroom cloth mounting plate 3, to form a composite cleaning surface. The final end is fixed on the receiving tray 10. When a cleaning action is required, the stepper motor 9 starts and drives the receiving tray 10 to rotate, thereby pulling the cleanroom cloth 8 forward a preset distance and conveying a clean cloth surface to the cleaning position. The nozzle to be cleaned moves above the composite cleaning surface and presses down during the dispensing interval. The nozzle tip first contacts the cleanroom cloth 8 made of the cleanroom cloth body 7. The elasticity of the cleanroom cloth body 7 is used to remove the sticky adhesive residue. Then, the surface cleanroom cloth 8 completes the fine wiping, removing small particles and dust, achieving a double cleaning effect. The driven wheel 2 applies a constant tension to the cleanroom cloth 8 throughout the conveying process to ensure the flatness of the cleaning contact surface.

[0032] During operation, photoelectric sensor 4 monitors the running status of cleanroom cloth 8 in real time to prevent production from being affected by abnormalities such as cloth belt breakage or jamming. Photoelectric switch 1, located at the feeding tray 6, continuously monitors the remaining roll diameter of cleanroom cloth 8. When cleanroom cloth 8 is about to run out, its roll diameter decreases, the detection light path of photoelectric switch 1 is no longer blocked, and a warning signal is triggered. After receiving the signal, the operator can prepare a new roll in advance and quickly complete the replacement during the interval of equipment operation without stopping the whole machine, thereby avoiding production interruption caused by material replacement.

[0033] The entire mechanism is precisely driven by the stepper motor 9 to achieve automated step-by-step conveying of the cleaning cloth belt. The combination of the adhesive cotton body 7 and the dust-free cloth 8 achieves efficient dual cleaning. Furthermore, the residual material warning function of the photoelectric switch 1 ultimately achieves the goal of replacing consumables without stopping the machine. All components are integrated on the adhesive wiping mechanism base plate 5 to form a compact and efficient automated cleaning assembly.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
