Description

Technical Field

[0001] The utility model relates to the technical field of mask production equipment, in particular to an ear strap connecting device for mask production which is easy to position. Background Art

[0002] A mask is a sanitary product worn over the nose and mouth to filter air, thereby protecting against harmful gases and germs. Masks in use vary in size. For example, adult and children's masks are significantly different in size, so the ear straps attached to the edges of different sizes also vary in size.

[0003] With the increasing prevalence of automation, in automated mask production, an earband gripper picks up the earband, bends it 90°, places the ends of the earband on the edge of the mask, and then secures it to the mask using an ultrasonic welder. However, existing earband grippers cannot adjust the horizontal spacing between the earbands, resulting in an inability to adjust the length of the earband when picking it up. To address this issue, we propose an earband connection device for mask production that facilitates positioning. Utility Model Content

[0004] The utility model provides an ear strap connection device for mask production that is easy to position. It has the advantages of allowing the rotation of the manipulator to be controlled by a drive motor, high rotation accuracy, and accurate positioning when picking up the ear strap, thereby solving the problems raised in the above-mentioned background technology.

[0023] The following will clearly and completely describe the technical solution of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figures 1 to 5 The utility model provides a technical solution: an ear strap connection device for mask production that is easy to position, including a support frame, which is a support device for the entire ear strap connection device. Figure 1 and Figure 2As shown, the specific structure of the support frame includes two parallel supports 1, each of which has a vertical bracket 4 mounted vertically on top. The two vertical brackets 4 are connected by at least one reinforcement bracket 7. A U-shaped frame 2 is provided on the side of each vertical bracket 4, with its opening facing the vertical bracket 4 and its ends connected to the vertical bracket 4. During use, the support frame 1 is fastened to the mask production equipment with bolts to fix the support frame.

[0025] The present application also includes a strip mounting plate 20, such as Figure 1 As shown, the strip mounting plate 20 is located on one side of the support frame, and both ends of the strip mounting plate 20 are connected to the vertical first guide rail 6 through the first slider 3, and the first guide rail 6 is fixed on the support frame, as shown in FIG. Figure 1 As shown, specifically, the two first guide rails 6 are respectively installed on the side of the U-shaped frame 2 away from the vertical bracket 4;

[0026] It should be noted that other structures of the ear band connecting device are to be installed on the side of the strip mounting plate 20. The U-shaped frame 2 provided can advance the strip mounting plate 20 forward so that there is a certain distance between the strip mounting plate 20 and the vertical bracket 4, thereby avoiding the possibility that other structures installed on the side of the strip mounting plate 20 will not touch the vertical bracket 4.

[0027] The specific structure on the side of the strip mounting plate 20 will be described below; Figure 1 and Figure 2 As shown, a second guide rail 10 is horizontally mounted on the side of the strip-shaped mounting plate 20. Two second sliders 5 are symmetrically arranged on the second guide rail 10. Each second slider 5 is provided with a positioning mechanism to fix it. The positioning mechanism is a positioning bolt threaded on the second slider 5. Tightening the positioning bolt can abut against the surface of the second guide rail 10, and the second slider 5 can move left and right along the second guide rail 10, thereby adjusting the distance between the two second sliders 5. When the position of the second slider 5 is adjusted, it can be locked and fixed with the positioning bolt. In addition, in order to facilitate the observation of the specific position of the second slider 5, a scale is provided on the surface of the second guide rail 10 (not shown in the figure). The scale is engraved in relief to prevent the scale protrusion from affecting the sliding of the second slider 5.

[0028] Next, a vertical downward mounting shaft 12 is provided on the side of each second slider 5. A bearing seat 11 is provided on the side of each second slider 5. The mounting shafts 12 are rotatably mounted within the bearing seats 11, and the two are connected via bearings. A drive mechanism is also provided on the top of the second slider 5, connected to the top of the mounting shaft 12. The drive mechanism includes a drive motor 8 mounted on the top of the mounting shaft 12. The drive motor 8 is mounted on a motor seat 9, one end of which is connected to the second slider 5. The drive motor 8 is a servo motor with high control precision, and the drive motor 8 drives the mounting shaft 12 to rotate.

[0029] Each mounting shaft 12 is provided with a manipulator at the bottom thereof, which is used to pick up the mask strap. The driving motor 8 drives the mounting shaft 12 to rotate at an angle of 0-90°. Figure 1 As shown, the robot is in the state of zero angle at this time, and Figure 2 The manipulator is rotated 90 degrees. The specific structure of the manipulator includes a fixed seat 24, the bottom of which is symmetrical and rotatably connected to two bar seats 14. There is a certain distance between the two bar seats 14, and the distance is used for the two bar seats 14 to be closed.

[0030] like Figure 4 and Figure 5 As shown, one end of each of the two strip seats 14 is connected to a downward-angled strip clamping arm 15, and the distal end of each strip clamping arm 15 is connected to a clamping portion 16, which is a rubber block. The other ends of the two strip seats 14 are connected by a spring 25. The ends of the two strip seats 14 away from the strip clamping arm 15 are connected to a vertically upward-extending strip plate 13. Each strip plate 13 has an outwardly flared L-shaped bend 22 at the top, and magnets 23 are mounted on the opposing surfaces of the two L-shaped bends 22.

[0031] It should be noted that the tops of the two strip plates 13 are designed to be in the shape of an L-shaped bend 22 in order to increase the distance between the tops of the strip plates 13. Because an electromagnet 21 is provided in the middle position between the two L-shaped bends 22 and the electromagnet 21 is mounted on the mounting shaft 12, this allows for sufficient installation space for the electromagnet 21.

[0032] The polarity of both ends of the electromagnet 21 here is the same as that of the magnet 23, so that when the electromagnet 21 is energized, it is used to push the magnet 23 to move to both sides thereof. At this time, the magnet 23 is away from the electromagnet 21, and the electromagnet 21 drives the bar seat 14 to rotate around the bottom of the fixing seat 24. The bar seat 14 drives the two bar clamping arms 15 to close, causing the clamping portion 16 at the end of the bar clamping arm 15 to close, thereby clamping the mask strap. The whole process is to allow the magnet 23 to drive the two clamping portions 16 to close. Just turn on and off the power to the electromagnet 21. When the electromagnet 21 is de-energized, the clamping portion 16 returns to its initial position under the pulling force of the spring 25.

[0033] The strip plate 13 , the strip seat 14 , the strip clamping arm 15 , and the clamping portion 16 are all made of non-magnetic materials, such as aluminum alloy, stainless steel, or other non-magnetic materials.

[0034] Furthermore, the entire earband connection device also requires lifting motion, so a lifting mechanism is provided on the side of the strip mounting plate 20 away from the manipulator. The lifting mechanism includes a mounting base 19 disposed in the middle of the strip mounting plate 20. A telescopic mechanism 17 is connected below the mounting base 19. The bottom of the telescopic mechanism 17 is connected to the connecting base 18, and both ends of the connecting base 18 are connected to the support 1.

[0035] The telescopic mechanism 17 can be a cylinder, an electric lifting rod or a hydraulic cylinder. The telescopic mechanism 17 can also be a linear drive module, such as a screw linear drive module or a linear motor.

[0036] In summary, the earband connecting device proposed in this application is arranged on one side of the earband feeding mechanism. When the earband is discharged, it is located below the strip clamp arm 15. Of course, at this time, the lifting mechanism is in the raised state, so that the strip clamp arm 15 is located above the earband.

[0037] Then the strip clamp arm 15 descends, allowing the ear strap to be located between the clamping parts 16 and clamping the ear strap, and then the ear strap feeding mechanism automatically cuts the ear strap;

[0038] Afterwards, the driving motor 8 drives the two ends of the ear strap to rotate 90 degrees, and then lowers it under the drive of the lifting mechanism, so that the two ends of the ear strap are placed on the edge of the mask, and then fixed by welding with an ultrasonic welding machine.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
