Description

Technical Field

[0001] This invention relates to the technical field of mask production, specifically to a production and testing device for 3D-fitting masks. Background Technology

[0003] The production of 3D masks typically involves two steps: ear loop assembly and folding, welding, and edge sealing. Existing 3D mask machines usually position the semi-finished product using a positioning block, then manually hold it in place. The ear loops are then assembled using an ear loop assembly machine, attaching them to the mask with adhesive. After assembly, the semi-finished product is manually folded in half. Finally, the edges of the semi-finished product are sealed using an ultrasonic welding machine, completing the production of a 3D mask.

[0004] Regarding the aforementioned technical conditions, there is also a defect that, after the ear loops are installed on the mask, the stability of the ear loops is not tested. As a result, some loose ear loops are easy to fall off the mask during use, leading to a poor user experience.

[0005] Based on this, the present invention designs a production and testing device for 3D-fitting masks to solve the above problems. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a production and testing device for 3D-fitting masks, comprising a placement platform, a placement plate, and a testing rod. The placement plate is fixedly mounted on the placement platform, the mask is placed on the placement plate, and the ear loops are located outside the placement plate. A movable seat is movably mounted on the placement platform, a cylinder is vertically fixedly mounted on the movable seat, an mounting plate is fixedly mounted on the telescopic shaft of the cylinder, and a fixed plate is vertically fixedly mounted on the mounting plate. The testing rod is rotatably mounted on the fixed plate, and a telescopic spring is mounted on the fixed plate. One end of the telescopic spring is fixedly connected to the testing rod. The testing rod is inserted into the ear loops, and the testing rod touches the ear loops downwards. After the testing rod moves downwards a certain distance, the testing rod rotates upwards and disengages from the ear loops.

[0007] By adopting the above technical solution, after the mouth is placed on the placement plate, the driving cylinder extends the cylinder's telescopic shaft, and then the moving seat moves towards one side of the placement plate, allowing the detection rod to be inserted into the ear loop. Then, the driving cylinder retracts the telescopic shaft, at which point the detection rod touches the ear loop downwards. As the detection rod moves downwards, the ear loop is inspected. When the ear loop is not secure, it falls off the mask. When the ear loop does not fall off, the detection rod rotates upwards, thereby achieving the effect of detecting the ear loop's secureness.

[0008] Preferably, the cross-section of the placement plate is inverted V-shaped.

[0009] By adopting the above technical solution, when the mask is placed on the placement plate, the V-shaped design facilitates the ear loops to fall out, thereby making it easier for the detection rod to be inserted into the ear loops.

[0010] Preferably, an installation cylinder is fixedly installed on the fixing plate, a telescopic rod is inserted into the installation cylinder, an abutment spring is fixedly connected between the telescopic rod and the bottom of the installation cylinder, and one end of the telescopic rod abuts against the mask.

[0011] By adopting the above technical solution, the telescopic rod abuts against the mask, preventing the mask from popping up when the detection rod is removed, thus stabilizing the mask's placement.

[0012] Preferably, an abutment wheel is rotatably provided on the telescopic rod, and the abutment wheel abuts against the mask.

[0013] By adopting the above technical solution, the abutment rollers come into contact with the mask, reducing friction and thus reducing damage to the mask.

[0014] Preferably, two movable seats are correspondingly provided on the placement platform.

[0015] By adopting the above technical solution, two detection rods can simultaneously detect two ear loops, improving work efficiency.

[0016] Preferably, the placement plate has air blowing holes facing the mask.

[0017] By adopting the above technical solution, after the mask is placed on the placement plate, the air hole blows air into the mask, reducing the amount of waste material left on the mask from the previous process.

[0018] Preferably, the placement plate has a movable groove, in which a movable block is movably disposed. The placement plate is provided with a tactile switch and a fan. The tactile switch is electrically connected to the fan. The mask is located between the movable block and the abutting wheel. When the abutting wheel abuts against the mask, the movable block contacts the tactile switch, and the tactile switch turns on the fan to work.

[0019] By adopting the above technical solution, when the contact wheel touches the mask, the contact moving block moves toward the tactile switch, thereby allowing the tactile switch to turn on the fan and prevent the fan from blowing continuously when the contact wheel is not in contact with the mask, thus reducing the chance of the mask falling off the placement plate.

[0020] In summary, this application has the following beneficial technical effects: After the mouth is placed on the placement plate, the driving cylinder extends the cylinder's telescopic shaft, and then the moving seat moves towards one side of the placement plate, allowing the detection rod to be inserted into the ear loop. Then, the driving cylinder retracts the telescopic shaft, at which point the detection rod touches the ear loop downwards. As the detection rod moves downwards, the ear loop is inspected. When the ear loop is not secure, it falls off the mask. When the ear loop does not fall off, the detection rod rotates upwards, thereby achieving the effect of detecting the ear loop's secureness.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] Reference Figures 1-6 A production and testing device for 3D-fitted masks includes a placement platform 1, a placement plate 2, and a testing rod 3. A support column 4 is vertically fixed on the placement platform 1, and the placement plate 2 is fixed on the support column 4. The cross-section of the placement plate 2 is inverted V-shaped. The mask 5 is placed on the placement plate 2, and the ear loops 6 are located outside the placement plate 2. A movable seat 7 is movably disposed on the placement platform 1. In this embodiment, the movable seat 7 is moved by a lead screw, and a motor 8 serves as the power source for the lead screw. Reference Figures 1-6 A cylinder 9 is vertically fixed on the movable seat 7. A mounting plate 10 is fixed on the telescopic shaft of the cylinder 9. A fixing plate 11 is vertically fixed on the mounting plate 10. There are two fixing plates 11. The detection rod 3 is rotatably positioned between the two fixing plates 11. A telescopic spring 12 is provided on the fixing plate 11. One end of the telescopic spring 12 is fixedly connected to the detection rod 3. The telescopic spring 12 pulls the detection rod 3, keeping the detection rod 3 in a horizontal state when it is not in contact.

[0027] Reference Figures 1-6 During testing, the drive cylinder 9 extends its telescopic shaft, and the drive motor 8 moves the lead screw to move the moving seat 7 toward the placement plate 2, allowing the detection rod 3 to be inserted into the ear loop 6. Then, the drive cylinder 9 retracts the telescopic shaft, at which point the detection rod 3 touches the ear loop 6 downwards. As the detection rod 3 moves downwards, the ear loop 6 is inspected. After moving a specified distance, if the ear loop 6 is not secure, it will detach from the mask 5. If the ear loop 6 does not detach from the mask 5, it will rotate upwards against the detection rod 3, eventually causing the detection rod 3 to disengage from the ear loop 6, thus achieving the effect of testing the ear loop's secureness.

[0028] Reference Figures 1-6 After the inspection is completed, drive motor 8, so that lead screw drives moving seat 7 to move away from the placement plate 2, thus completing the inspection of ear strap 6.

[0029] Reference Figures 1-6 The cross-section of the placement plate 2 is inverted V-shaped. When the mask 5 is placed on the placement plate 2, the V-shaped design makes it easy for the ear loops 6 to fall out, thus making it easy for the detection rod 3 to be inserted into the ear loops 6. There are two movable seats 7 on the placement platform 1. The two detection rods 3 can detect the two ear loops 6 at the same time, improving work efficiency.

[0030] Reference Figures 1-6An installation cylinder 13 is fixedly installed on the fixed plate 11. A telescopic rod 14 is inserted into the installation cylinder 13. An abutment spring 15 is fixedly connected between the telescopic rod 14 and the bottom of the installation cylinder 13. An abutment wheel 16 is rotatably installed on the telescopic rod 14. After the moving seat 7 moves toward the placement plate 2, the abutment wheel 16 first abuts against the mask 5. Then, the detection rod 3 is inserted into the ear loop 6. Under the abutment of the abutment spring 15, the abutment wheel 16 presses against the mask 5. As the cylinder 9 contracts, the installation cylinder 13 moves down with the fixed plate 11. The abutment wheel 16 moves down along the surface of the placement plate 2. When the detection rod 3 is no longer in contact with the ear loop 6, the abutment wheel 16 is still abutting against the mask 5. Reference Figures 1-6 When the moving seat 7 moves away from the placement plate 2, the abutting wheel 16 disengages from the mask 5. Since the ear loop 6 has a certain elasticity, after the detection rod 3 disengages from the ear loop 6, the abutting wheel 16 abuts against the mask 5 to prevent the mask 5 from flying up. During the inspection, the mask 5 is placed stably on the placement plate 2, thereby reducing the chance of the mask 5 falling off.

[0031] Reference Figures 1-6 Two movable seats 7 are correspondingly provided on the placement platform 1, and two corresponding mounting cylinders 13 are also correspondingly provided on the placement platform 1. The two abutting wheels 16 abut against the mask 5 at the same time and move down at the same time, which can prevent the mask 5 from moving down when the abutting wheel 16 on one side moves.

[0032] Reference Figures 1-6 The placement plate 2 has a movable groove 17, in which a movable block 18 is movably disposed. The placement plate 2 is provided with a tactile switch 19 and a fan 20. A connecting plate 21 is fixedly disposed on the placement plate 2, and the tactile switch 19 is fixedly disposed on the connecting plate 21. A return spring 23 is connected between the connecting plate 21 and the movable block 18. The tactile switch 19 is located in the movable groove 17. The fan 20 is fixedly disposed on the placement plate 2, and the tactile switch 19 is electrically connected to the fan 20. In this embodiment, the fan 20 is a fan 20 with a battery. The mask 5 is located between the movable block 18 and the abutment wheel 16. The placement plate 2 has multiple air holes 22, which face the mask 5. The fan 20 is located below the air holes 22. Reference Figures 1-6 When the contact wheel 16 touches the mask 5, the contact wheel 16 pushes the mask 5 towards the moving block 18 and simultaneously pushes the moving block 18 towards the tactile switch 19 until the moving block 18 contacts the tactile switch 19. At this time, the tactile switch 19 turns on the fan 20. When the contact wheel 16 touches the mask 5, the fan 20 works, and the air blows out from the air hole 22 to blow air onto the mask 5, blowing off the punching waste remaining on the surface of the mask 5, thereby reducing the amount of waste remaining on the mask 5.

[0033] The implementation principle of this embodiment is as follows: During testing, the drive cylinder 9 extends its telescopic shaft, and then the drive motor 8 moves the lead screw to move the moving seat 7 toward the placement plate 2, allowing the detection rod 3 to be inserted into the ear loop 6. Then, the drive cylinder 9 retracts the telescopic shaft, at which point the detection rod 3 touches the ear loop 6 downwards. As the detection rod 3 moves downwards, the ear loop 6 is inspected. After moving a specified distance, if the ear loop 6 is not secure, it will fall off the mask 5. If the ear loop 6 does not fall off the mask 5, it will rotate upwards against the detection rod 3, eventually causing the detection rod 3 to disengage from the ear loop 6, thus achieving the effect of testing the ear loop's secureness.
