Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a device for applying adhesive to the end face of a motor housing. Background Technology
[0002] In the motor manufacturing process, to achieve a sealed connection between the motor housing and other components, a ring of sealant is often applied to the end face of the motor housing using a motor gluing device. This device typically includes a robotic arm, a gluing mechanism, and a cleaning mechanism. The gluing mechanism has a dispensing head for distributing the sealant. During the gluing process, the robotic arm drives the gluing mechanism along a preset path, aligning the dispensing head with the end face of the motor housing and moving it along the end face, thus evenly applying the sealant to the end face of the motor housing to form a sealing ring. After one or more gluing operations, the robotic arm drives the gluing mechanism to the cleaning mechanism, which cleans any remaining sealant from the dispensing head end face of the gluing mechanism, ensuring a stable sealant output for subsequent gluing operations. In existing technology, the cleaning mechanism includes an unwinding roller, a take-up roller, and a cleaning cloth. When cleaning the dispensing head is required, a robotic arm drives the dispensing mechanism to the cleaning cloth, ensuring that the end face of the dispensing head is in contact with the cleaning cloth. Then, the unwinding roller releases the cleaning cloth, and the take-up roller rewinds it. The cleaning cloth and the dispensing head undergo relative displacement, thereby wiping away any residual sealant from the dispensing head, thus completing the cleaning process. This cleaning method only utilizes a localized area of the cleaning cloth, resulting in a significant waste of unused cleaning cloth and hindering efforts to reduce consumable costs in the dispensing operation. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a glue-applying device for the end face of a motor housing, which helps to reduce the consumable costs of glue-applying operations.
[0004] According to an embodiment of the present invention, a motor housing end face gluing device includes a frame, a robot arm mounted on the frame, an output end of the robot arm connected to a gluing mechanism, and a gluing mechanism having a glue dispensing head; a base slidably connected to the frame; an unwinding roller rotatably connected to the base; a take-up roller rotatably connected to the base; a cleaning cloth, one end of which is wound around the unwinding roller and the other end connected to the take-up roller; the robot arm being used to drive the gluing mechanism to move so that the end face of the glue dispensing head abuts against the cleaning cloth between the unwinding roller and the take-up roller; and a linear drive mechanism mounted on the frame, the linear drive mechanism being used to drive the base to reciprocate along the width direction of the cleaning cloth.
[0005] It has at least the following beneficial effects: When the adhesive applicator is performing the adhesive applicator operation on the motor housing end face, the robotic arm on the frame will drive the adhesive applicator to move according to the preset adhesive applicator path, so that the adhesive outlet of the adhesive applicator is aligned with the end face of the motor housing and moves at a uniform speed. At the same time, the adhesive applicator will stably output sealant, so that a uniform sealant ring is formed on the end face of the motor housing. After the glue application is completed, the robotic arm drives the glue application mechanism to the cleaning cloth between the unwinding and take-up rollers, so that the glue outlet end face of the glue application mechanism comes into contact with the cleaning cloth between the unwinding and take-up rollers. Then, the unwinding and take-up rollers rotate simultaneously, and the take-up roller rewinds the cleaning cloth released by the unwinding roller. At the same time, the linear drive mechanism drives the base to move back and forth along the width direction of the cleaning cloth. The unwinding roller, take-up roller and cleaning cloth on the base move back and forth synchronously along the width direction of the cleaning cloth, thereby causing relative displacement between the cleaning cloth and the end face of the glue outlet. This allows the cleaning cloth to wipe and clean the residual sealant at the end face of the glue outlet using different areas of the cleaning cloth. After cleaning the glue outlet, the robotic arm drives the glue application mechanism to perform the glue application operation again, and the equipment can enter the next glue application cycle. This motor housing end face gluing equipment makes the cleaning cloth reciprocate synchronously along the width direction during the winding and unwinding process. This allows the end face of the glue dispensing head to not only have relative displacement with the length direction of the cleaning cloth, but also to fully contact all areas in the width direction of the cleaning cloth. This maximizes the use of the available cleaning area of the cleaning cloth, making full use of the cleaning cloth and thus helping to reduce the consumable cost of the gluing operation.
[0006] The adhesive coating device for the end face of the motor housing according to an embodiment of the present utility model further includes a tensioning mechanism, which is disposed on the base and between the unwinding roller and the take-up roller. The tensioning mechanism is used to maintain tension on the cleaning cloth between the unwinding roller and the take-up roller.

The second pressure roller is floatingly connected to the base and disposed between the two second traction rollers. The cleaning cloth is wound around the two second traction rollers, and the second pressure roller presses on the cleaning cloth.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0020] refer to Figure 1 , Figure 5 , Figure 8 and Figure 9 This utility model discloses a glue coating device for the end face of an electric motor housing, including a frame 600, a base 610, an unwinding roller 100, a winding roller 200, a cleaning cloth 300, and a linear drive mechanism 400. A robot arm 620 is mounted on the frame 600. The output end of the robot arm 620 is connected to a glue applicator 630, which has a glue dispensing head 631. A base 610 is slidably connected to the frame 600. An unwinding roller 100 is rotatably connected to the base 610. A take-up roller 200 is rotatably connected to the base 610. One end of a cleaning cloth 300 is wound around the unwinding roller 100, and the other end of the cleaning cloth 300 is connected to the take-up roller 200. The robot arm 620 is used to drive the glue applicator 630 to move so that the end face of the glue dispensing head 631 abuts against the cleaning cloth 300 between the unwinding roller 100 and the take-up roller 200. A linear drive mechanism 400 is mounted on the frame 600 and is used to drive the base 610 to reciprocate along the width direction of the cleaning cloth 300.
[0021] It should be explained that the width direction of the cleaning cloth 300 is the left-right direction. The linear drive mechanism 400 is used to drive the base 610 and the unwinding roller 100, the winding roller 200 and the cleaning cloth 300 on the base 610 to move synchronously in the left-right direction. As an embodiment of this utility model, the frame 600 is provided with two slide rails parallel to the left-right direction, and the base 610 is provided with two sliders, which are respectively slidably connected to the two slide rails. In this utility model, the unwinding roller 100 is fitted with a rolled cleaning cloth 300. The unwinding roller 100 and the winding roller 200 can be common expansion and contraction rollers. The winding roller 200 is fitted with a paper tube. The other end of the cleaning cloth 300 is connected to the paper tube by adhesive tape, which will not be further described here. In this utility model, the adhesive coating equipment for the end face of the motor housing also includes a first motor 120 and a second motor 220. Both the first motor 120 and the second motor 220 are mounted on the frame 600. The output end of the first motor 120 is connected to the unwinding roller 100, and the output end of the second motor 220 is connected to the take-up roller 200. The first motor 120 is used to drive the unwinding roller 100 to rotate, and the second motor 220 is used to drive the take-up roller 200 to rotate. Further details will not be elaborated here.
[0022] Understandably, when the adhesive applicator is normally performing the adhesive applicator operation on the motor housing end face, the robotic arm 620 on the frame 600 will drive the adhesive applicator 630 to move according to the preset adhesive applicator path, so that the adhesive outlet 631 of the adhesive applicator 630 is aligned with the end face of the motor housing and moves at a uniform speed. At the same time, the adhesive applicator 630 stably outputs sealant, so that a uniform sealant ring is formed on the end face of the motor housing. After the adhesive applicator operation is completed, the robotic arm 620 drives the adhesive applicator 630 to move to the cleaning cloth 300 between the unwinding roller 100 and the take-up roller 200, so that the end face of the adhesive outlet 631 of the adhesive applicator 630 abuts against the cleaning cloth 300 between the unwinding roller 100 and the take-up roller 200. Subsequently, the unwinding roller 100 and the take-up roller 200 rotate simultaneously, and the take-up roller 200 rewinds the cleaning cloth 300 released by the unwinding roller 100. At the same time, the linear drive mechanism 400 drives the base 610 along the width of the cleaning cloth 300. The unwinding roller 100, winding roller 200, and cleaning cloth 300 on the base 610 move back and forth synchronously along the width direction of the cleaning cloth 300. This causes relative displacement between the cleaning cloth 300 and the end face of the dispensing head 631, allowing different areas of the cleaning cloth 300 to wipe and clean the residual sealant on the end face of the dispensing head 631. After cleaning the dispensing head 631, the robot arm 620 drives the glue coating mechanism 630 to perform glue coating operations again, and the equipment can enter the next glue coating cycle. This motor housing end face glue coating equipment, by causing the cleaning cloth 300 to move back and forth synchronously along the width direction during the unwinding and winding process, allows the end face of the dispensing head 631 to not only have relative displacement with the length direction of the cleaning cloth 300, but also to fully contact all areas of the cleaning cloth 300 in the width direction. This maximizes the use of the usable cleaning area of the cleaning cloth 300, making full use of the cleaning cloth 300 and thus helping to reduce the consumable cost of the glue coating operation.
[0023] It should be further explained that, in this embodiment of the utility model, the adhesive coating equipment for the motor housing end face drives the base 610, the unwinding roller 100, and the winding roller 200 to move synchronously along the width direction of the cleaning cloth 300 via the linear drive mechanism 400. This allows the cleaning cloth 300 to reciprocate along its own width direction. In conjunction with the unwinding action of the unwinding roller 100 and the winding action of the winding roller 200, the adhesive dispensing head 631 can fully utilize all available areas in the length and width directions of the cleaning cloth 300. Only after all areas of a single roll of cleaning cloth 300 have been used for cleaning and become ineffective does it need to be replaced with a new cleaning cloth 300. This significantly extends the service life of a single roll of cleaning cloth 300, reduces the number of times and the total amount of cleaning cloth 300 need to be replaced per unit time, and thus reduces the consumable cost of replacing the cleaning cloth 300.
[0024] refer to Figures 3 to 5The motor housing end face gluing equipment also includes a tensioning mechanism 500, which is mounted on the base 610 and located between the unwinding roller 100 and the take-up roller 200. The tensioning mechanism 500 is used to maintain the tension of the cleaning cloth 300 between the unwinding roller 100 and the take-up roller 200. Understandably, under the action of the tensioning mechanism 500, the cleaning cloth 300 between the unwinding roller 100 and the take-up roller 200 maintains tension, which can prevent the cleaning cloth 300 from wrinkling or shifting due to slack. This ensures that when the base 610 moves back and forth along the width of the cleaning cloth 300, the end face of the cleaning cloth 300 and the adhesive dispensing head 631 always maintains a uniform and tight contact, preventing incomplete cleaning of residual sealant on the adhesive dispensing head 631 due to insufficient contact. On the other hand, during the unwinding process of the unwinding roller 100 and the take-up roller 200, the tension can counteract the tension fluctuations generated during the unwinding and take-up of the cleaning cloth 300, maintain the stability of the movement of the cleaning cloth 300, and prevent the cleaning cloth 300 from being overstretched or slack due to uneven tension. This ensures that every usable area of the cleaning cloth 300 can effectively participate in cleaning, reducing the need to replace the cleaning cloth 300 prematurely due to local failure or poor cleaning effect. Therefore, it also helps to reduce the consumable cost of the adhesive application operation.
[0025] refer to Figures 3 to 5 , Figure 7 and Figure 8 The tensioning mechanism 500 includes a first pressure roller 510 and two first traction rollers 520. The first pressure roller 510 and the two first traction rollers 520 are parallel to the width direction of the cleaning cloth 300. The two first traction rollers 520 are rotatably connected to the base 610. The first pressure roller 510 is floatingly connected to the base 610. The first pressure roller 510 is located between the two first traction rollers 520. The cleaning cloth 300 is wrapped around the two first traction rollers 520. The first pressure roller 510 presses on the cleaning cloth 300. The tensioning mechanism 500 also includes a second pressure roller 530 and two second traction rollers 540. The second pressure roller 530 and the two second traction rollers 540 are parallel to the width direction of the cleaning cloth 300. The two second traction rollers 540 are rotatably connected to the base 610. The two second traction rollers 540 are located between the take-up roller 200 and the first traction roller 520 on the side near the take-up roller 200. The second pressure roller 530 is floatingly connected to the base 610 and is located between the two second traction rollers 540. The cleaning cloth 300 is wound around the two second traction rollers 540, and the second pressure roller 530 presses on the cleaning cloth 300.
[0026] Understandably, the cleaning cloth 300 is wound around two first traction rollers 520 and two second traction rollers 540. The two first traction rollers 520 and two second traction rollers 540 provide a stable winding path for the cleaning cloth 300 through rotational support, allowing the cleaning cloth 300 to move smoothly. The first pressure roller 510 is floatingly connected to the base 610 and presses on the cleaning cloth 300 between the two first traction rollers 520. The first pressure roller 510 continuously applies vertical pressure to the cleaning cloth 300 between the two first traction rollers 520 by its own weight, so as to significantly increase the tension of this section of the cleaning cloth 300, thereby increasing the tension of the cleaning cloth 300 between the unwinding roller 100 and the take-up roller 200. Similarly, the second pressure roller 530 continuously applies vertical pressure to the cleaning cloth 300 between the two second traction rollers 540 by its own weight, thereby increasing the tension of the cleaning cloth 300 between the unwinding roller 100 and the take-up roller 200. The first pressure roller 510 prevents the cleaning cloth 300 from slack during the initial unwinding stage, while the second pressure roller 530 counteracts tension fluctuations that may occur during the winding process, ensuring controllable tension of the cleaning cloth 300 throughout the entire unwinding and winding process. The dual-stage tensioning action of the first pressure roller 510 and the second pressure roller 530 ensures that the cleaning cloth 300 receives stable tension throughout the entire unwinding and winding process, preventing wrinkles, shifts, or localized slack in the cleaning cloth 300.
[0027] refer to Figure 6 Both ends of the first traction roller 520 are provided with first limiting protrusions 521, and the area between the two first limiting protrusions 521 is used for the movement of the cleaning cloth 300. Both ends of the second traction roller 540 are provided with second limiting protrusions, and the area between the two second limiting protrusions is used for the movement of the cleaning cloth 300. It can be understood that during the length direction movement of the cleaning cloth 300 as it is unwound by the unwinding roller 100 and wound by the winding roller 200, and during the reciprocating movement of the cleaning cloth 300 along its own width direction with the base 610, the two first limiting protrusions 521 and the two second limiting protrusions can limit and guide the cleaning cloth 300, so as to restrict the cleaning cloth 300 from deviating or shifting along its own width direction, and ensure that the cleaning cloth 300 always moves stably. The two first limiting protrusions 521 and the two second limiting protrusions can ensure the relative position stability of the cleaning cloth 300 and the dispensing head 631, and avoid insufficient contact or contact position displacement between the cleaning cloth 300 and the end face of the dispensing head 631 due to the displacement of the cleaning cloth 300, thereby ensuring the thorough cleaning of residual sealant in the dispensing head 631.
[0028] refer to Figure 3 , Figure 4 and Figure 8The base 610 has a clearance hole 611 extending along the width of the cleaning cloth 300. A support rod 650 is mounted on the frame 600, passing through the clearance hole 611. The support rod 650 is located below the cleaning cloth 300 between the unwinding roller 100 and the take-up roller 200. The upper end of the support rod 650 can abut against the adhesive dispensing head 631 through the cleaning cloth 300. Understandably, during cleaning operations, the end face of the adhesive dispensing head 631 presses against the cleaning cloth 300. The support rod 650 provides stable support from below the cleaning cloth 300, preventing the cleaning cloth 300 from sinking or deforming due to force. This ensures uniform and sufficient contact pressure between the adhesive dispensing head 631 and the cleaning cloth 300, thereby guaranteeing the cleaning cloth 300's ability to remove residual sealant from the end face of the adhesive dispensing head 631 and improving the cleaning effect of the cleaning cloth 300. On the other hand, the clearance hole 611 extends along the width direction of the cleaning cloth 300, and the support rod 650 passes through the clearance hole 611, so that when the base 610 moves back and forth along the width direction of the cleaning cloth 300, the support rod 650 does not hinder the movement of the base 610, and can always maintain a fixed relative position with the dispensing head 631, thereby enabling the support rod 650 to always abut against the dispensing head 631 through the cleaning cloth 300.
[0029] In this invention, the dispensing head 631 abuts against the cleaning cloth 300 between the first traction roller 520 near the take-up roller 200 and the second traction roller 540 near the unwind roller 100. A support rod 650 is provided below the cleaning cloth 300 between the first traction roller 520 near the take-up roller 200 and the second traction roller 540 near the unwind roller 100. In this invention, the two first traction rollers 520 and the two second traction rollers 540 have the same diameter, and their axes are on the same horizontal plane. It is understood that having the same diameter and axes on the same horizontal plane ensures that the cleaning cloth 300 between the first traction roller 520 near the take-up roller 200 and the second traction roller 540 near the unwind roller 100 remains flat, preventing the cleaning cloth 300 from tilting and failing to fully contact the dispensing head 631.
[0030] refer to Figures 1 to 4The motor housing end face adhesive coating equipment also includes a first cover 110 and a second cover 210. The first cover 110 is mounted on the frame 600 and has a first material passage hole 111. The unwinding roller 100 is located inside the first cover 110, and the cleaning cloth 300 passes through the first material passage hole 111. The second cover 210 is mounted on the frame 600 and has a second material passage hole. The winding roller 200 is located inside the second cover 210, and the cleaning cloth 300 passes through the second material passage hole. Understandably, the first cover 110 encloses the unwinding roller 100, and the second cover 210 encloses the take-up roller 200. The first cover 110 and the second cover 210 can effectively isolate external dust and debris from contact with the unwinding roller 100, the take-up roller 200, and the cleaning cloth 300, preventing impurities from adhering to the surface of the cleaning cloth 300 and affecting the cleaning effect. They can also prevent foreign objects from being rolled into the rotating unwinding roller 100 and the take-up roller 200, causing equipment failure. On the other hand, the first feed hole 111 and the second feed hole can play a limiting and guiding role for the cleaning cloth 300, further constraining the movement path of the cleaning cloth 300 and preventing the cleaning cloth 300 from deviating during the unwinding and take-up process.
[0031] refer to Figure 9 The motor housing end face adhesive application equipment also includes a positioning mechanism 640, which is used to position the motor housing. Understandably, the function of the positioning mechanism 640 is to precisely fix the position of the motor housing, preventing displacement during adhesive application, ensuring that the end face of the motor housing is precisely aligned with the preset adhesive application path of the adhesive dispensing head 631, so that the sealant can be evenly applied to the designated area on the end face of the motor housing, thereby forming a qualified sealing ring. The robotic arm 620, adhesive application mechanism 630, and positioning mechanism 640 are all common components in adhesive application equipment and will not be described further here.
[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0033] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
