Description

Technical Field

[0001] The invention relates to the technical field of glue dispensing equipment, and in particular to an automatic and efficient glue erasing system and a glue erasing method. Background Art

[0002] The cleaning and wiping mechanism is an automated device for automatic cleaning of the dispensing needle or nozzle. When the workstation is determined, the needle will be wiped accurately and easily. It is one of the necessary mechanisms for factory automation, and its purpose is to improve the efficiency of the factory and realize the scale of production. The utility model CN216396906U discloses a semi-automatic dispensing and laminating device, wherein the glue cleaning unit is arranged between the dispensing and laminating conveying unit and the feed conveying unit, and is located below the dispensing unit, and is used to wipe the dispensing needle. It also discloses that the fixed block is provided with an alcohol injection needle connection, and the alcohol injection needle is located at the upper end of the connecting plate. The injection port of the alcohol injection needle is located above the clamping channel, and is used to soak the dust-free cloth with alcohol. The automatic dispensing and glue-joining box is arranged on the connecting plate, and the automatic dispensing and glue-joining box is provided with a accommodating chamber, and the accommodating chamber is used to store the residual glue in the dispensing needle, improve the cleaning effect, and protect the cleanliness of the equipment. However, in this device, the utilization rate of the dust-free cloth is low, which is easy to cause waste; and the glue dispensing needle needs to be clamped with a clamp assembly during the glue wiping process, which restricts the movement of the needle and makes it difficult to control the friction during the glue wiping. When the glue wiping force is small, the glue cannot be wiped clean, and when the glue wiping force is large, it is easy to damage the needle. In addition, when the needle is not used for a long time, the residual glue at the end of the needle cannot be wiped off by the non-woven fabric, causing the glue to solidify in the needle easily, resulting in increased maintenance costs. Summary of the invention

[0003] The invention discloses an automatic and efficient glue erasing system, aiming to improve the problems of low efficiency, poor effect and serious waste of the existing glue erasing system.

[0004] The present invention adopts the following scheme:

[0006] The needle soaking device comprises a soaking cup connected to the cleaning liquid feeding device, wherein the soaking cup contains cleaning liquid for storing the needle, thereby preventing the glue in the needle from solidifying during the storage period;

[0007] The wiper device includes a material rolling mechanism and an infiltration mechanism, wherein the material rolling mechanism includes two reel devices arranged on both sides of the infiltration mechanism, and each reel device is provided with a stepping motor for controlling the wiping cloth on the reel device to realize forward transmission or reverse transmission to improve the utilization rate of the wiping cloth; the infiltration mechanism is arranged below the wiping cloth, and includes an infiltration platform, an infusion mechanism and an elastic member, wherein the infusion mechanism is connected to the cleaning liquid feeding device, and the infiltration platform is arranged on the infusion mechanism through the elastic member;

[0010] Furthermore, the eraser device is arranged on the rodless cylinder and the guide rail so as to drive the eraser device to adjust the depth following the position of the needle.

[0011] Furthermore, the infiltration platform is made of a deformable material.

[0012] Furthermore, it also includes a waste liquid collecting device, which is connected to the soaking cup to discharge the cleaning liquid in the soaking cup at a regular time.

[0013] Furthermore, the infiltration table is provided with a pressure sensor, which is suitable for identifying the pressure of the needle on the infiltration table and transmitting the pressure data to the control system. The control system is configured to drive the infusion mechanism to infuse liquid into the infiltration table and control the stepper motor to work to perform the eraser action when the pressure reaches a preset value.

[0014] Furthermore, the infiltration mechanism is also provided with an ultrasonic device, and the ultrasonic device is suitable for being used in the soaking cup to ultrasonically clean the needle stored in the soaking cup.

[0015] The present invention also provides an automatic glue erasing method, using any one of the automatic and efficient glue erasing systems, the steps comprising:

[0016] When erasing glue, the motion mechanism moves the needle to the top of the erasing station, drives the needle down to fit the dust-free cloth, and presses the dust-free cloth to the infiltration station;

[0017] When the pressure on the infiltration station reaches a preset value, the control system controls the infusion mechanism to deliver cleaning liquid to the non-woven fabric, and controls the stepper motor to drive the reel device to rotate so that the wiping cloth transmits a preset length, thereby wiping the needle, and recording the working rhythm of the stepper motor to obtain the position of the unwiped part of the wiping cloth, and continuing to work until the wiping cloth roll of the feeding reel device reaches the preset alarm margin;

[0018] At this time, if a new wiping cloth roll is replaced, the stepper motor rotates in the original direction; if the wiping cloth roll is not replaced, the stepper motor rotates in the reverse direction, and the unwiped part of the wiping cloth is transmitted to the top of the infiltration table so as to use the unwiped part to wipe the needle, thereby improving the utilization rate of the wiping cloth;

DETAILED DESCRIPTION

[0025] Example 1

[0026] Combination Figure 1 and Figure 2 As shown, this embodiment provides an automatic and efficient glue erasing system, comprising: a cleaning liquid feeding device 1, a glue erasing device 2 and a needle soaking device 3; wherein,

[0027] The needle soaking device 3 comprises a soaking cup connected to the cleaning liquid feeding device 1, wherein the soaking cup contains cleaning liquid for storing the needle, thereby preventing the glue in the needle from solidifying during storage;

[0028] The eraser device 2 includes a material rolling mechanism and an infiltration mechanism 24, wherein the material rolling mechanism includes two reel devices 21 arranged on both sides of the infiltration mechanism 24, and each reel device 21 is provided with a stepping motor 22 for controlling the wiping cloth on the reel device 21 to realize forward transmission or reverse transmission to improve the utilization rate of the wiping cloth; the infiltration mechanism 24 is arranged below the wiping cloth, and includes an infiltration platform 241, an infusion mechanism 242 and an elastic member 243, wherein the infusion mechanism 242 is connected to the cleaning liquid feeding device 1, and the infiltration platform 241 is arranged on the infusion mechanism 242 through the elastic member 243;

[0029] When wiping glue, the needle is suitable for moving to the top of the wiping cloth and pressing the wiping cloth onto the wetting table 241, the infusion mechanism 242 is suitable for delivering cleaning liquid to the wetting table 241 to soak the wiping cloth, and the stepping motor 22 is suitable for driving the reel device 21 to rotate so that the wiping cloth wipes the needle.

[0030] Combination Figure 1 and Figure 2 As shown, in this embodiment, the glue erasing device 2 is arranged on the rodless cylinder 4 and the guide rail 5, so as to drive the glue erasing device 2 to adjust the depth following the position of the needle. Through this arrangement, it can adapt to the change of the dispensing position, reduce the movement stroke of the needle during glue erasing, and thus improve the working efficiency. For example, when the dispensing position changes continuously along a straight line, the rodless cylinder 4 can drive the glue erasing device 2 as a whole to follow the change of the dispensing position and move to the closest position, so as to reduce the stroke of the needle for glue erasing after the dispensing is completed, and improve the glue erasing efficiency.

[0031] The coiling mechanism is provided with two reel devices 21 for installing the wiping cloth roll and for recovering the wiping cloth roll respectively. Specifically, a stepper motor 22 is provided on each of the two reel devices 21, and the stepper motor 22 can drive the reel device 21 to rotate forward or reverse simultaneously, so as to realize forward transmission or reverse transmission of the wiping cloth. A plurality of transmission rollers 23 are also provided on the coiling mechanism for transmitting the wiping cloth at the wiping position. An infiltration mechanism 24 is provided below the wiping cloth at the wiping position, and the infiltration mechanism 24 is used to transport cleaning liquid to the wiping cloth to infiltrate the wiping cloth when wiping, so as to improve the wiping effect. Here, the infiltration platform 241 is made of a deformable material, for example, a sponge with a higher density can be used. The infusion mechanism 242 can pass through the infiltration platform 241 or be provided in the infiltration platform 241, and is used to transport the cleaning liquid to the infiltration platform 241. When wiping the glue, the needle moves to the top of the wiping position and presses the wiping cloth down onto the soaking platform 241, and the soaking platform 241 soaks the wiping cloth, thereby achieving the effect of wet wiping. It should be noted that in this embodiment, the soaking platform 241 is installed on the infusion mechanism 242 through the elastic member 243. When the needle has a large downward stroke, the soaking platform 241 will not produce destructive force on the needle under the elastic action of the elastic member 243 and the deformability of the soaking platform 241 itself, which can effectively prevent the needle from being damaged. In addition, since the soaking platform 241 is made of a deformable material, when the needle presses the wiping cloth down onto the soaking platform 241, the soaking platform 241 deforms downward at the needle, and the wiping cloth is correspondingly pressed into the deformation groove of the soaking platform 241, so that the wiping cloth can partially wrap the edge of the needle, thereby increasing the area of ​​wiping the glue, so as to improve the efficiency and effect of wiping the glue.

[0032] In another embodiment, the infiltration station 241 is provided with a pressure sensor, and the pressure sensor is suitable for identifying the pressure of the needle on the infiltration station 241, and transmitting the pressure data to the control system, and the control system is configured to drive the infusion mechanism 242 to infuse the infiltration station 241 and control the stepper motor 22 to work to perform the wiping action when the pressure reaches a preset value. The working time of the infusion mechanism 242 can be controlled by the pressure sensor to prevent the waste of cleaning liquid. In addition, this setting cooperates with the stepper motor 22, and the wiping can be started only when there is a certain pressure between the needle and the wiping cloth, so as to prevent the friction between the wiping cloth and the needle from being small and resulting in poor wiping effect, thereby improving the wiping effect.

[0033] In a preferred embodiment, each of the reel devices 21 is provided with a roll material remaining amount detection device to detect the remaining amount of the wiping cloth on the reel device 21; the roll material remaining amount detection device may be a photoelectric sensor, etc. The transmission direction of the wiping cloth in the initial state is defined as forward transmission, and the stepper motor 22 is suitable for controlling the forward transmission of the wiping cloth to a preset distance to wipe the needle head; when the roll material remaining amount detection device detects that the remaining amount of the wiping cloth of the feeding reel device 21 reaches the preset remaining amount, the two stepper motors 22 reverse to make the wiping cloth reversely transmitted, and use the wiping cloth that has not wiped the needle head during forward transmission to wipe the needle head. Here, when the stepper motor 22 rotates, it can automatically record the working rhythm, that is, it can automatically record the parts that have been wiped and the parts that have not been wiped during the transmission process of the wiping cloth. During the working process of the winding mechanism, when the needle is wiped once, the stepper motor 22 will continue to drive a certain distance when the needle moves up to separate from the wiping cloth to prevent the edge of the wiped area from affecting the unwiped area, so that unwiped areas are formed on the wiping cloth at equal intervals. When a wiping cloth roll is wiped in the forward transmission, if a new wiping cloth roll is not replaced in time within a certain period of time, the stepper motor 22 can be driven to rotate in the reverse direction to drive the wiping cloth to rotate in reverse. Since the stepper motor 22 has recorded the position of the unwiped part of the wiping cloth roll during the forward transmission, the unwiped part can be controlled to move to the glue wiping position for wiping during the reverse transmission, so that the unwiped part during the forward transmission can be utilized, and the residual glue in the wiped part can be prevented from affecting the wiping effect. This solution can fully utilize the wiping cloth roll when there is no time to replace a new wiping cloth roll, thereby reducing the waste of the wiping cloth roll and reducing the time for replacing the cloth roll, thereby improving the efficiency of wiping glue.

[0034] In this embodiment, the cleaning liquid feeding device 1 is used to store the cleaning liquid, and the cleaning liquid is connected to the infusion mechanism 242 and the needle soaking mechanism through a pipeline. The needle soaking device 3 includes a soaking cup, in which cleaning liquid is stored for storing the needle, thereby preventing the glue in the needle from solidifying during the storage period; the soaking cup is also provided with a drain port, which is connected to the waste liquid collection device 6. A solenoid valve is also provided between the drain port and the waste liquid collection device 6, and the solenoid valve can be opened and closed regularly to discharge the cleaning liquid in the soaking cup regularly, and provide new cleaning liquid through the cleaning liquid feeding device 1. By regularly replacing the cleaning liquid, the cleaning liquid can be prevented from being invalid, especially the cleaning liquid containing alcohol. In a preferred embodiment, the infiltration mechanism 24 is also provided with an ultrasonic device, which is suitable for use in the soaking cup to ultrasonically clean the needle stored in the soaking cup. The ultrasonic device also helps to discharge the residual glue in the needle.

[0035] In addition, a glue dripping groove is provided on one side of the erasing position, and the needle can be placed still or shaken above the glue dripping groove before erasing to discharge most of the glue into the glue dripping groove by dripping, thereby reducing the erasing burden of the erasing device 2.

[0036] Through the scheme of this embodiment, the efficiency and effect of erasing glue can be effectively improved, and the utilization rate of the wiping cloth can be improved.

[0037] Example 2

[0038] The present invention also provides an automatic glue erasing method, using the automatic and efficient glue erasing system, the steps include:

[0039] When erasing glue, the needle is moved to the top of the erasing station by the motion mechanism, the needle is driven down to be close to the dust-free cloth, and the dust-free cloth is pressed toward the infiltration station 241;

[0040] When the pressure on the infiltration station 241 reaches a preset value, the control system controls the infusion mechanism 242 to deliver cleaning liquid to the non-woven fabric, and controls the stepper motor 22 to drive the reel device 21 to rotate so that the wiping cloth transmits a preset length, thereby wiping the needle, and records the working rhythm of the stepper motor 22 to obtain the position of the unwiped part of the wiping cloth, and continues to work until the wiping cloth roll of the feeding reel device 21 reaches a preset alarm margin;

[0041] At this time, if a new wiping cloth roll is replaced, the stepper motor 22 rotates in the original direction; if the wiping cloth roll is not replaced, the stepper motor 22 rotates in the reverse direction, and the unwiped part of the wiping cloth is transmitted to the top of the infiltration station 241 so as to use the unwiped part to wipe the needle, thereby improving the utilization rate of the wiping cloth;

[0042] After the needle is wiped, if no dispensing work is performed again within a preset time, it moves to the immersion mechanism 24 to immerse the needle in the immersion cup. The immersion cup discharges the cleaning liquid regularly and provides new cleaning liquid through the cleaning liquid feeding device 1.

[0043] Through the method of this embodiment, the glue wiping can be automated and the glue wiping efficiency is high. In addition, the glue liquid in the needle can be effectively prevented from solidifying when it is placed for a long time.

[0044] It should be understood that the above are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.

[0045] The above description of the drawings used in the implementation manner only illustrates certain embodiments of the present invention and should not be regarded as limiting the scope.
