Description

Technical Field

[0001] The invention relates to the technical field of gas mask production, and in particular to a gas mask lens and cover body assembly production device. Background Art

[0002] Gas masks can filter harmful substances in the air. As an important part of gas masks, the eye window is related to the mask's field of vision retention rate and the matching of optical equipment, and has a great impact on the physiological state and work of personnel. The gas masks currently on the market are of binocular window type and monocular large eye window type. However, no matter what type of mask lens, hard lenses are used. The connection between the lens and the mask body is assembled by screw-tightening clamps. A certain force is applied to the rubber at the eye window of the mask body to deform the rubber at the part in contact with the lens, thereby achieving airtightness of the mask eye window.

[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figures 1 to 13 As shown, a specific embodiment of a gas mask lens and cover body assembly production device of the present invention, for the convenience of understanding, the gas mask is used as the application scenario of the present invention, wherein the gas mask includes a cover body 10, a lens 11, an upper buckle 12 and a lower buckle 13, and the cover body 10 is further divided into a bearing part 14, a connecting part 15 and an installation part 16, all of which are prior arts and will not be elaborated herein.

[0035] The gas mask lens and cover body assembly production device includes a workbench 20, a placement table 30, an adsorption module, a first supporting mechanism, a second supporting mechanism, a supporting frame 50, an opening mechanism, a lens installation module and a clamping component.

[0036] The placement table 30 is arranged on the workbench 20 and is used to fix the cover body 10. The adsorption module can adsorb the cover body 10 on the placement table 30, which can help the cover body 10 to be flattened. The first supporting mechanism can squeeze and fix the bearing part 14, and the second supporting mechanism can support the connecting part 15, and at the same time can push the mounting part 16 to make it turn into a horizontal state. The opening mechanism is installed on the support frame 50, which can open the mounting part 16. The lens mounting module can install the lens 11 into the mounting part 16, and the clamping assembly can clamp and fix the two buckles to facilitate screwing and fixing.

[0037] like Figures 1 to 6 An operating panel 21 is provided in the middle of the workbench 20, and a placing table 30 is fixedly installed on the upper surface of the operating panel 21. A boss 31 is provided on the upper surface of the placing table 30, so that a step is formed on the outer side of the boss 31. In this embodiment, the bottom surface of the step is inclined. When working, the cover body 10 can pass through the boss 31 and be sleeved on the step, and the bearing portion 14 will be close to the bottom surface of the step.

[0038] The adsorption module includes adsorption holes 32 distributed on the bottom surface of the step, and an annular cavity 34 is arranged at the bottom of the placement table 30. All the adsorption holes 32 are connected to the annular cavity 34. The side of the placement table 30 is provided with air holes 35 connected to the annular cavity 34. The air holes 35 are connected to an air pump (not shown in the figure), so that the adsorption holes 32 can generate suction to firmly adsorb the bearing part 14 of the cover body 10 on the placement table 30. The distributed adsorption holes 32 can help the cover body 10 to flatten its bearing part 14 on the placement table 30 during installation, which is convenient for subsequent extrusion and fixation. In addition, the worker can detach from the cover body 10, and the subsequent fixing link does not need to be manually adjusted.

[0039] like Figures 5 to 8 The first supporting mechanism includes an installation chamber 40 opened on the boss 31, and the boss 31 is provided with one in four directions, front, back, left, and right. The installation chambers 40 are all open structures. Sliding blocks 41 are horizontally and sealedly installed in the installation chambers 40. A fixed block 42 is fixedly installed at the end of the sliding block 41. The fixed block 42 is a bottom opening structure, and an extrusion membrane 43 is fixedly arranged near the bottom. The extrusion membrane 43 is made of rubber. A vertical ventilation duct 44 is arranged at the center of the placement table 30. The ventilation duct 44 is connected to the four installation chambers 40, and a one-way valve 45 is installed at the connection point.

[0040] After the air is inflated into the ventilation pipe 44 , the gas enters the installation chamber 40 through the one-way valve 45 , thereby pushing the sliding block 41 and the fixed block 42 to slide outward. After the fixed block 42 moves to the outside, it is just located above the bearing portion 14 .

[0041] A first air passage 46 communicating with the ventilation pipe 44 is further provided below the installation chamber 40, and a second air passage 47 communicating with the interior of the fixing block 42 is provided on the sliding block 41, and the other end of the second air passage 47 opens downward. When the sliding block 41 moves outward to the extreme position, the second air passage 47 is just communicated with the first air passage 46 (such as Figure 8 At this time, the gas in the ventilation duct 44 continues to enter the fixing block 42 through the second air channel 47 and the first air channel 46, thereby increasing the internal air pressure, forcing the extrusion film 43 to expand downward and bulge out of shape, and the extrusion film 43 presses the upper surface of the bearing portion 14 downward, thereby achieving extrusion and fixing of the cover body 10.

[0042] After the work is completed, when the fixed block 42 needs to be reset, the ventilation pipe 44 starts to pump air, the first air channel 46 is connected to the third air channel 48, and the third air channel 48 is also connected to the installation chamber 40, and a piston 49 is installed in the third air channel 48 through a spring. When the first air channel 46 is in the inflated state, the piston 49 blocks the third air channel 48. Due to the setting of the one-way valve 45, the gas in the installation chamber 40 cannot return to the original path, so when the ventilation pipe 44 starts to pump air, only the first air channel 46 is in the pumping state, and the gas in the fixed block 42 is first pumped out, and then the pumping state will cause the piston 49 to release the blockage of the third air channel 48, so that the first air channel 46 is connected to the installation chamber 40, so that the gas in the installation chamber 40 is pumped out through the third air channel 48 and the first air channel 46, and the interior is in a negative pressure state. At this time, the sliding block 41 will drive the fixed block 42 to retract into the installation chamber 40. The working principle of the four fixing blocks 42 is the same, and the cover body 10 can be fixed in four directions: front, back, left, and right.

[0043] like Figure 5 A bottom cavity 33 is provided at the bottom of the placement table 30. The bottom cavity 33 is located inside the annular cavity 34 and is connected to the ventilation pipe 44. An air pipe 36 is connected to the bottom cavity 33. The air pipe 36 is connected to an air pump (not shown in the figure), so as to realize the inflation and deflation of the ventilation pipe 44.

[0044] like Figure 4When the first supporting mechanism completes the fixation of the cover body 10, the second supporting mechanism starts to work. The second supporting mechanism includes a cylinder installed under the workbench 20. A lifting frame 22 is fixedly installed on the output end of the cylinder. A first top block 23 is arranged at the front and rear positions and the right side of the lifting frame 22. A second top block 24 is also arranged separately on the left side of the first top block 23. The second top block 24 is controlled separately by another cylinder. The four top blocks are respectively located in the front, rear, left and right directions of the cover body 10. Through holes are opened on the operating panel 21 at the corresponding positions. When the four top blocks rise, they will abut against the outer side of the connecting portion 15 on the cover body 10. It should be noted that the shapes of the four top blocks match the shapes of the corresponding connecting portions 15, so that the top blocks can better play a fixing role.

[0045] When the four top blocks continue to rise, they will push against the mounting portion 16. In the original state, the mounting portion 16 is tilted, which makes it inconvenient to install the lens 11. Therefore, as the top blocks push, the four corners of the mounting portion 16 gradually turn into a horizontal state, and the parts connected to the four corners also turn into a horizontal state, so that the inner side can be opened later, thereby facilitating the installation of the lens 11.

[0046] It is particularly noted that, since the left side portion of the cover body 10 is an inward-retracted structure, based on the special shape, the second top block 24 cannot contact the connecting portion 15 when it is directly raised, so a sliding unit is also provided.

[0047] The sliding unit includes a slide seat 25 slidably mounted on the bottom of the second top block 24. The telescopic part of the cylinder is fixedly connected to the bottom of the slide seat 25. The second top block 24 can slide left and right along the slide seat 25. Side panels 27 are provided on both sides of the through hole on the operating panel 21 through which the second top block 24 passes. A guide groove 28 is opened on the inner side surface of the side panel 27. The guide groove 28 has a vertical section and an inclined section. Slide columns 26 are provided on the front and rear sides of the second top block 24. The slide columns 26 are located in the guide groove 28.

[0048] The second push block 24 will first rise along the vertical section of the guide groove 28 , and then move obliquely upward through the inclined section, and finally push the left mounting portion 16 .

[0049] After the first supporting mechanism and the second supporting mechanism complete the fixing of the cover body 10 , the opening mechanism starts to work to open the inner side of the mounting portion 16 .

[0050] In this embodiment, the spreading mechanism includes a driving unit and a spreading unit.

[0051] like Figure 2 , Fig. 9 and Fig.10The opening unit includes a support frame 51 which can be lifted and lowered on a support frame 50. A cylinder is installed on the support frame 50. The support frame 51 is fixedly connected to the telescopic part of the cylinder. The cylinder can drive the support frame 51 to lift and lower. The support frame 51 is generally annular in structure, and a plurality of slide grooves are evenly opened along its circumference. Clamping blocks 60 are slidably installed in the slide grooves. The clamping blocks 60 can slide along the radial direction of the support frame 51.

[0052] A horizontal frame 63 is installed on the clamping block 60 for horizontal sliding, and a vertical frame 64 is installed on the horizontal frame 63 for vertical sliding. Both the horizontal frame 63 and the vertical frame 64 are provided with fixing bolts, so that after the horizontal frame 63 and the vertical frame 64 have completed sliding, the bolts can be manually tightened to fix them.

[0053] A swivel seat 65 is installed at the bottom of the vertical frame 64 through damping rotation, and a spreading claw 66 is rotatably installed on the swivel seat 65 through a torsion spring. In a non-working state, the spreading claw 66 is in a horizontal state and faces a direction away from the center of the supporting frame 51.

[0054] The spreading claw 66 can be rotated downward, and the maximum rotation angle is 60 degrees.

[0055] According to the shape of the cover body 10 to be processed, the positions of the horizontal frame 63 and the vertical frame 64 are manually adjusted before work, and the swivel seat 65 is rotated at the same time, so that after the supporting frame 51 is lowered, all the opening claws 66 can just face the mounting part 16 of the cover body 10. At the same time, after the opening claws 66 collide with the mounting part 16, the swivel seat 65 will also make adaptive rotation.

[0056] It is particularly noted that, in this embodiment, the width of the spreading claw 66 is relatively narrow. Due to the irregular shape of the cover body 10 and the inclined portion of the mounting portion 16 , the spreading claw 66 is designed to be relatively narrow to facilitate better insertion into the inner side of the mounting portion 16 .

[0057] When the carrier 51 descends, all the opening claws 66 are facing the mounting portion 16. Since the mounting portion 16 has been adjusted to a horizontal state, the driving unit drives all the clamping blocks 60 to slide outward along the sliding groove, so that all the opening claws 66 are inserted into the inner side of the mounting portion 16. Then the cylinder drives the carrier 51 to rise, and the opening claws 66 will gradually rotate downward as it rises, so that the opening claws 66 open the mounting groove on the inner side of the mounting portion 16.

[0058] The driving unit includes a swivel ring 52 rotatably mounted on a carrier frame 51, a driving ring 53 is arranged on the outer side of the swivel ring 52, and the driving ring 53 has a uniform wave-shaped structure. A gear ring 54 is also fixedly mounted on the swivel ring 52. A motor is mounted on the carrier frame 51, and a driving gear is mounted on the output end of the motor. The driving gear is meshed with the gear ring 54, thereby driving the gear ring 54 to rotate.

[0059] The clamping block 60 is rotatably mounted with an adjusting wheel 61, and a rubber ring 62 is arranged in the groove of the adjusting wheel 61. The rubber ring 62 is elastic and is sleeved on all the adjusting wheels 61 (such as Fig.10 As shown in the figure, the elastic force of the rubber ring 62 will make all the adjusting wheels 61 have a force tending to the center direction and abut against the driving ring 53. When the clamping block 60 needs to move, the gear ring 54 rotates, and the wavy surface on the outside will push the adjusting wheel 61 to drive the clamping block 60 to move outward. The rubber ring 62 will be stretched, thereby realizing the movement of the opening claw 66, and the opening claw 66 can be controlled to be inserted into the mounting portion 16.

[0060] When the opening claws 66 open the mounting portion 16 , the lens mounting module is then required to install the lens 11 into the mounting portion 16 .

[0061] Continue back Figure 1 and Figure 2 The lens installation module includes a suction cup 80 that can be lifted and lowered on the support frame 50. A cylinder is installed on the support frame 50. The suction cup 80 is fixedly connected to the telescopic part of the cylinder. The suction surface of the suction cup 80 is an arc-shaped structure that matches the shape of the lens 11. When the lens 11 needs to be installed, the worker first manually installs the lens 11 on the suction cup 80, and then the cylinder drives the suction cup 80 to descend until the lens 11 enters the installation part 16 of the cover body 10.

[0062] Then the spreading mechanism rises and leaves the cover body 10, and the second supporting mechanism gradually begins to descend, so that the mounting portion 16 gradually resumes its tilted state, and at the same time the suction cup 80 continues to descend until the lens 11 is completely pressed into the mounting portion 16, and then the suction cup 80 separates from the lens 11 and rises, and at the same time the first supporting mechanism and the second supporting mechanism are reset to release the fixation of the cover body 10, thereby completing the installation of the lens 11.

[0063] Then, the upper buckle 12 and the lower buckle 13 are installed. The worker manually installs the two buckles on the cover body 10 to fix the lens 11. After the installation is completed, the bolts need to be tightened to lock it.

[0064] Since the fixation of the cover body 10 and the lens 11 mainly relies on the tight squeezing of the two buckles and is fixed by tightening the side screws, the buckles that have been installed may deviate from their originally predetermined positions due to uneven force during the manual tightening of the screws, resulting in the inability to effectively ensure the consistency of the product status. Therefore, it is necessary to clamp the buckles through a clamping assembly.

[0065] like Figure 2 and Fig. 9The clamping assembly includes a clamping frame 70 slidably mounted on the carrier frame 51. There are two clamping frames 70, one on each of the left and right sides of the carrier frame 51. A cylinder is mounted on the carrier frame 51. The clamping frame 70 is fixedly connected to the telescopic part of the cylinder. The shapes of the two carrier frames 51 match the shapes of the two buckles respectively.

[0066] When in use, the support frame 51 drives the clamping frame 70 to descend to a suitable height, and then the cylinders on both sides respectively drive the clamping frame 70 to move toward the center, clamp the two buckles and fix them, and then tighten the screws, and finally remove the installed mask.

[0067] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
