[0028] Reference Figures 1 to 10 According to the first aspect of the present application, the brush assembly device includes: a material taking head 100, a vacuum generator (not shown in the figure), a first positioning structure 200, a second positioning structure 300, a positioning driver 400 and a moving module 500.

[0029] The material taking head 100 is provided with an air passage 110 and an air hole 120 , and the air passage 110 is connected to the air hole 120 ; a vacuum generator, connected to the air passage 110 , so as to allow the air holes 120 to draw air in to attract the brush 920 ; The first positioning structure 200 is provided on the material dispensing head 100 and is used to penetrate into the first positioning hole 921 of the brush 920; The second positioning structure 300 is movably disposed on the material taking head 100; The positioning driver 400 is driven and connected to the second positioning structure 300, and is used to drive the second positioning structure 300 to descend so as to penetrate into the second positioning hole 931 of the assembly component 930; The moving module 500 drives and connects to the material taking head 100 , and is used to drive the material taking head 100 to approach the brush 920 or the part to be assembled 930 .

[0030] For example, in some embodiments, reference Figure 6 and Figure 8 The air hole 120 is opened at the lower end of the material taking head 100. One end of the air channel 110 can be connected to the vacuum generator, and the other end is connected to the air hole 120. When the vacuum generator is operating, the air hole 120 can absorb air. Figure 5 and Figure 6 The first positioning structure 200 is columnar and is disposed through the material taking head 100, and the lower end of the first positioning structure 200 passes through the lower end of the material taking head 100. Figure 6 and Figure 7 The second positioning structure 300 is columnar and can be lifted and lowered through the material reclaiming head 100. The positioning driver 400 is fixedly connected to the material reclaiming head 100. The positioning driver 400 specifically includes a cylinder. Under the drive of the positioning driver 400, the lower end of the second positioning structure 300 can pass through the lower end of the material reclaiming head 100 and be lower than the lower end of the first positioning structure 200, or retract into the material reclaiming head 100. Figure 1 The moving module 500 specifically includes a connected lifting module and a translation module, so as to drive the material head 100 to lift and translate, and at the same time drive the first positioning structure 200, the second positioning structure 300 and the positioning driver 400 to move.

[0031] One of the operating modes of the brush assembly device of the present application is as follows: the moving module 500 drives the material taking head 100 to move above the brush 920, referring to Figure 9, the brush 920 has a first positioning hole 921, and the first positioning structure 200 is aligned with the first positioning hole 921. Subsequently, the mobile module 500 drives the material picking head 100 to descend. During the descent of the material picking head 100, the lower end of the material picking head 100 gradually approaches the brush 920, and the first positioning structure 200 penetrates into the first positioning hole 921. The material picking head 100 and the brush 920 are against or close to a distance where the brush 920 can be sucked up by suction. Next, the vacuum generator operates, the air hole 120 sucks air, and the brush 920 is adsorbed to the lower end of the material picking head 100. Then, the mobile module 500 drives the material picking head 100 to rise and translate to the top of the part to be assembled 930, with reference to Figure 9 The part to be assembled 930 is specifically a plastic part and is provided with a second positioning hole 931 and a protrusion 932. The first positioning structure 200 is aligned with the protrusion 932. At the same time, the second positioning structure 300 is aligned with the second positioning hole 931 on the part to be assembled 930. Subsequently, the positioning driver 400 drives the second positioning structure 300 to descend. The lower end of the second positioning structure 300 protrudes from the lower end of the material removal head 100 and is lower than the first positioning structure 200, and penetrates into the second positioning hole 931. The moving module 500 drives the material removal head 100 to descend, and the material removal head 100 gradually approaches the part to be assembled 930. At the same time, the lower end of the first positioning structure 200 will also abut against the protrusion 932. The vacuum generator then stops operating, and the retrieving head 100 releases its suction force on the brush 920. Under the force of gravity, the brush 920 slides down along the first positioning structure 200 to the protrusion 932, allowing the protrusion 932 to penetrate the first positioning hole 921 of the brush 920, thereby completing the assembly of the brush 920 and the component to be assembled 930. After this, the moving module 500 drives the retrieving head 100 upward, causing the first positioning structure 200 to leave the first positioning hole 921. The positioning actuator 400 drives the second positioning structure 300 to rise and retract into the retrieving head 100, causing the second positioning structure 300 to leave the second positioning hole 931, allowing the retrieving head 100 to install the next brush 920.

[0032] In summary, during the retrieving process, the vacuum generator cooperates with the air holes 120 on the retrieving head 100 to absorb the brush 920, and the first positioning structure 200 penetrates the first positioning hole 921 of the brush 920, so that the relative position between the brush 920 adsorbed by the retrieving head 100 and the retrieving head 100 is accurate. During the assembly process, the positioning driver 400 cooperates with the second positioning structure 300 to penetrate the second positioning hole 931 of the component to be assembled 930, so that the relative position between the retrieving head 100 and the component to be assembled 930 is accurate. At the same time, the first positioning structure 200 and the second positioning structure 300 are both provided on the retrieving head 100. As a result, the relative position between the brush 920 and the component to be assembled 930 is accurate at this time. After the retrieving head 100 cancels the adsorption of the brush 920, the brush 920 can accurately fall along the first positioning structure 200 to the assembly position on the component to be assembled 930. Furthermore, the first positioning structure 200 can abut against the protrusion 932 on the to-be-assembled component 930 , so that the brush 920 can be guided onto the protrusion 932 by the first positioning structure 200 , thereby ensuring the position accuracy of the brush 920 .

[0033] It should also be understood that when the first positioning structure 200 cooperates with the air hole 120 to attract the brush 920, the second positioning structure 300 can be retracted into the material removal head 100 to provide a clearing mechanism. During assembly, the lower end of the second positioning structure 300 can be lower than the first positioning structure 200, allowing it to be pre-inserted into the second positioning hole 931 to calibrate the relative position between the component to be assembled 930 and the material removal head 100. Specifically, the second positioning structure 300 has a non-circular cross-section, and the cross-section of the second positioning hole 931 matches that of the second positioning structure 300. When the second positioning structure 300 is inserted into the second positioning hole 931, it can also correct the orientation of the component to be assembled 930.

[0034] In a further embodiment, referring to Figure 9 Two brushes 920 distributed along the circumference need to be assembled on a to-be-assembled part 930 of the potentiometer, and only one second positioning hole 931 is provided on the to-be-assembled part 930, and the second positioning hole 931 is located at the center of the to-be-assembled part 930. Therefore, two groups of first positioning structures 200 are provided, and two groups of air holes 120 are also provided, so that the material picking head 100 can pick up materials and assemble two brushes 920 at the same time, and only one group of second positioning structures 300 and positioning driver 400 needs to be provided on one material picking head 100.

[0035] In other embodiments, the first positioning structure 200 and the second positioning structure 300 may also be needle-shaped, ball-shaped, or other shapes, as long as they can be inserted into the first positioning hole 921 and the second positioning hole 931. The first positioning structure 200 and the second positioning structure 300 may also be directly disposed on the lower end or side of the material removal head 100. The positioning driver 400 may also be a motor or other driver. The moving module 500 may also be a robot.

[0036] Reference Figure 6 and Figure 8 According to some embodiments of the present application, the brush assembly device of the present application further includes a hair dryer (not shown in the figure), which is connected to the air duct 110 so that the air hole 120 blows air to press the brush 920 against the part to be assembled 930.

[0037] It can be understood that after the brush 920 is assembled to the part to be assembled 930, the fan is operated to blow air through the air duct 110 to the air hole 120, and the brush 920 is pressed against the part to be assembled 930 by the wind. Therefore, when the first positioning structure 200 leaves the first positioning hole 921 of the brush 920, the brush 920 can be prevented from being carried away by the first positioning structure 200 due to static electricity or other forces.

[0038] Specifically, in order to enable the air duct 110 to be connected to the hair dryer and the vacuum generator at the same time, a three-way valve can be provided at the air inlet of the air duct 110 to control the air duct 110 to selectively connect to the hair dryer or the vacuum generator.

[0039] Reference Figure 5 According to some embodiments of the present application, the first positioning structure 200 can be raised and lowered relative to the material taking head 100 .

[0040] It can be understood that during the material picking process, after the first positioning structure 200 passes through the first positioning hole 921 of the brush 920, it can abut against the supporting structure that supports the brush 920 (the supporting structure is, for example, the first punch 630 described below), and the first positioning structure 200 rises relative to the material picking head 100 to retract into the material picking head 100, so that the lower end of the material picking head 100 can be close to the brush 920 to absorb the brush 920. It should be understood that since the brush 920 has a certain thickness, when the material picking head 100 is close to the brush 920, the first positioning structure 200 will not be completely retracted into the material picking head 100, and at least part of the lower end of the first positioning structure 200 still remains passed through the first positioning hole 921. After the material picking head 100 completes the material picking and moves away from the supporting structure, the first positioning structure 200 descends relative to the material picking head 100 to extend out of the material picking head 100 to ensure the positioning effect of the brush 920, and in the later assembly process, the material picking head 100 can be placed without being too close to the part to be assembled 930, and the first positioning structure 200 can be against the protrusion 932 on the part to be assembled 930.

[0041] Reference Figure 5 According to some embodiments of the present application, the material taking head 100 is provided with an installation chamber 130, one end of the first positioning structure 200 is movably set in the installation chamber 130, and the other end can enter and exit the installation chamber 130, and is used to penetrate into the first positioning hole 921 of the brush 920, and an elastic member 150 is provided in the installation chamber 130, and the elastic member 150 abuts against one end of the first positioning structure 200, and is used to provide an elastic force for the other end of the first positioning structure 200 to extend out of the installation chamber 130.

[0042] It is understood that after the lower end of the first positioning structure 200 passes through the first positioning hole 921 of the brush 920 and abuts against the supporting structure, and the material removal head 100 continues to descend, the first positioning structure 200 pushes the elastic member 150 to compress, allowing the first positioning structure 200 to retract into the installation chamber 130, while allowing the material removal head 100 to continue to move downward to approach the brush 920. When the material removal head 100 completes the material removal and moves away from the supporting structure, the elastic member 150 expands to push the first positioning structure 200 out of the installation chamber 130.

[0043] Specifically, the inner wall of the installation chamber 130 forms a step structure 140, and the upper end of the first positioning structure 200 forms a larger flange 210. The outer diameter of the flange 210 is larger than the minimum inner diameter of the step structure 140. Therefore, the flange 210 cannot pass through the step structure 140. The flange 210 is offset from the side of the step structure 140 to limit the length of the first positioning structure 200 protruding from the material head 100, thereby preventing the first positioning structure 200 from detaching from the installation chamber 130.

[0044] Of course, in some other embodiments, the first positioning structure 200 may also be connected to the material retrieving head 100 via a cylinder, so that the first positioning structure 200 can be raised and lowered relative to the material retrieving head 100 to achieve a telescopic effect relative to the material retrieving head 100 .

[0045] Reference Figure 3 and Figure 4 According to some embodiments of the present application, the brush assembly device of the present application also includes a stamping mechanism 600, which includes a loading plate 610, a pressing plate 620, a first punch 630 and a punching driver 640. The loading plate 610 and the pressing plate 620 are used to pass the material strip 910 with the brush 920. The loading plate 610 is provided with a first punching hole 611, and the pressing plate 620 is provided with a second punching hole 621. The first punching hole 611 is opposite to the second punching hole 621. The first punch 630 is movably arranged in the first punching hole 611. The punching driver 640 drives the first punch 630 to drive the first punch 630 to pass through the first punching hole 611 and enter the second punching hole 621 to punch out the brush 920 on the material strip 910; the material taking head 100 can enter the second punching hole 621 to take away the brush 920.

[0046] It is understood that the brush 920 is formed by processing the material strip 910 through the upstream stamping and forming equipment, and when it is transmitted to the brush assembly equipment of the present application, ... the brush 920 is formed by processing the material strip Figure 10 The material strip 910 is formed with a brush 920 connected to the material strip 910, so the brush 920 needs to be punched off the material strip 910. The material strip 910 can be transferred between the carrier plate 610 and the pressing plate 620. The portion of the material strip 910 with the brush 920 corresponds to the first punching hole 611 of the carrier plate 610 and the second punching hole 621 of the pressing plate 620. Subsequently, the punching driver 640 drives the first punch 630 upward, and the first punch 630 passes through the first punching hole 611 and enters the second punching hole 621. At the same time, the first punch 630 cooperates with the second punching hole 621 to punch the brush 920 off the material strip 910. At this time, the brush 920 is located at the upper end of the first punch 630, and the upper end of the first punch 630 is located in the second punching hole 621. The material removal head 100 can enter the second punching hole 621 and remove the brush 920 from the upper end of the first punch 630. It should be understood that the first punching hole 611 can guide the rise and fall of the first punch 630, and the second punching hole 621 can cooperate with the first punch 630 to flush the brush 920 down. At the same time, the second punching hole 621 can also limit the brush 920 that has just been flushed down within the second punching hole 621 to prevent the brush 920 from being blown off the first punch 630 by wind or other factors. The second punching hole 621 guides the material removal head 100 so that the material removal head 100 can take the material.

[0047] Reference Figure 4 According to some embodiments of the present application, the first punch 630 is provided with a limiting hole 631 , and the first positioning structure 200 can penetrate into the limiting hole 631 .

[0048] It is understood that the limiting hole 631 is formed at the upper end of the first punch 630. Before the first punch 630 punches the material strip 910, the material removal head 100 can drive the first positioning structure 200 to first pass through the first positioning hole 921 of the brush 920 and into the limiting hole 631 of the first punch 630. As the first punch 630 rises to punch the material strip 910, the first punch 630 pushes the first positioning structure 200 upward, and the upper end of the first positioning structure 200 retracts into the material removal head 100, while the lower end of the first positioning structure 200 remains through the first positioning hole 921 of the brush 920 and into the limiting hole 631 of the first punch 630. After the first punch 630 punches the brush 920 downward, the first positioning structure 200 remains inserted into the first positioning hole 921 of the brush 920. Thus, by cooperating with the first punch 630, the first positioning structure 200 ensures the accuracy of the relative position of the brush 920 and the first positioning structure 200 during the process of the first punch 630 punching the material strip 910 and punching down the brush 920, thereby avoiding the problem that the position of the brush 920 is offset or flipped during the process of the brush 920 being punched down, resulting in the first positioning structure 200 being unable to accurately penetrate the first positioning hole 921 of the brush 920, and facilitating the material picking head 100 to accurately pick up materials.

[0049] Reference Figure 3 According to some embodiments of the present application, the stamping mechanism 600 also includes a second punch 650, which is located downstream of the first punch 630. The punching driver 640 also drives the second punch 650 to drive the second punch 650 to cooperate with the edge of the pressure plate 620 to cut the material strip 910.

[0050] It can be understood that after the first punch 630 punches the brush 920 off the material strip 910, the material strip 910 needs to be recovered, and the punching of the material strip 910 is continuous. The material strip 910 needs to be continuously transported forward, and the part of the material strip 910 where the brush 920 is punched off will be transported to the second punch 650. While the punching driver 640 drives the first punch 630 to rise to punch the material strip 910, the punching driver 640 can simultaneously drive the second punch 650 to rise, and the second punch 650 cooperates with the edge position of the pressure plate 620 to cut the material strip 910. The cut material strip 910 will fall and fall into the collection box below. Thus, by cutting the material strip 910 to facilitate its recovery, distributing the first punch 630 and the second punch 650 along the conveying direction of the material strip 910, and enabling the punching driver 640 to drive the first punch 630 and the second punch 650 at the same time, the use of the driver can be saved, and the two punching actions can be performed simultaneously, thereby simplifying the control program.

[0051] Reference Figure 1 and Figure 2 According to some embodiments of the present application, the brush assembly device of the present application also includes a jig 700, which is used to carry the part to be assembled 930. The jig 700 is provided with a liftable third positioning structure 710, which can penetrate into the second positioning hole 931 of the part to be assembled 930.

[0052] It is understood that after the jig 700 transfers the component to be assembled 930 to the assembly position, the third positioning structure 710 can rise to penetrate into the second positioning hole 931 of the component to be assembled 930 to initially position the component to be assembled 930 and pre-adjust the position of the component to be assembled 930. Subsequently, in some embodiments, during the assembly process, before the second positioning structure 300 penetrates into the second positioning hole 931 of the component to be assembled 930, the third positioning structure 710 first descends and exits the second positioning hole 931. In other embodiments, the third positioning structure 710 does not exit the second positioning hole 931 beforehand, and the second positioning structure 300 penetrates into the second positioning hole 931 of the component to be assembled 930 and pushes the third positioning structure 710 downward, allowing the third positioning structure 710 to exit the second positioning hole 931. It should be understood that the third positioning structure 710 is used to pre-position the part to be assembled 930 before assembly and to guide the insertion of the second positioning structure 300, but does not position the part to be assembled 930 during the assembly process. It is necessary to ensure that the specific position of the part to be assembled 930 is adjusted by the second positioning structure 300 to ensure that the position between the part to be assembled 930 and the brush 920 is accurate.

[0053] Reference Figure 1According to some embodiments of the present application, the brush assembly device of the present application also includes a material dispensing mechanism 800, which includes a translation drive 810, a lifting drive 820 and a material dispensing structure 830. The lifting drive 820 drives the connected material dispensing structure 830 to drive the material dispensing structure 830 to penetrate the third positioning hole 911 of the material belt 910. The translation drive 810 drives the connected material dispensing structure 830 to drive the material dispensing structure 830 to move along the conveying direction of the material belt 910.

[0054] It is understood that in order to transport the material belt 910 forward, Figure 10 A third positioning hole 911 is formed on the material strip 910. The translation driver 810 drives the lifting driver 820 to drive the material dipping structure 830 to translate so that the material dipping structure 830 is aligned with the third positioning hole 911 on the material strip 910. The lifting driver 820 drives the material dipping structure 830 to descend to penetrate into the third positioning hole 911. Then the translation driver 810 drives the material dipping structure 830 to translate. The material dipping structure 830 abuts against the inner wall of the third positioning hole 911 to push the material strip 910 to translate and transport.

[0055] Specifically, the material shifting structure 830 is columnar, and in order to ensure the stability of the conveying of the material belt 910, a plurality of material shifting structures 830 are provided.
