Description

Technical Field

[0001] The present invention relates to the field of dust-proof net assembly devices, and specifically to an adjustable dust-proof net assembly device. Background Art

[0002] At present, for many electronic products, such as speakers, headphones, etc., through the setting of dust-proof nets, dust, hair, fibers, etc. are prevented from entering the device, preventing them from adhering to electronic components, avoiding overheating damage of components caused by dust accumulation affecting heat dissipation, extending the service life of the device. For the sound generating units of devices such as speakers and headphones, it can prevent dust from entering and interfering with sound propagation, maintaining the purity and clarity of the sound quality.

[0003] The existing dust-proof nets are assembled by attaching a denser dust-proof net outside the protective housing to achieve a better dust-proof effect, and are assembled by bonding or hot melting methods to fix the dust-proof net and the protective housing to each other, so as to better protect the electronic product subsequently. The assembly device is assembled in cooperation with a hot melting head corresponding to the size of the protective housing through an electric telescopic machine tool. Through the up and down movement of the electric telescopic machine tool, the hot melting head is driven to weld and assemble between the dust-proof net and the protective housing, so as to integrally die-cast the protective housing and the dust-proof net, thereby improving the assembly efficiency of the dust-proof net.

[0004] Through the press-type assembly of the hot melting machine, the assembly between the dust-proof net and the protective housing can be quickly completed. However, the assembly size of the existing assembly device for the dust-proof net is fixed, and when the user needs to perform hot melting operations on dust-proof nets of different sizes, it cannot quickly adapt to different sizes, thereby reducing the use efficiency of the device.

[0021] By adopting the above technical solution, it is ensured that the first limiting block can smoothly limit the dust-proof net and the protective housing under the drive of the first sliding rod.

[0022] Further, the linkage rod is designed in an L-shaped structure, and the linkage rod is slidably connected to the first sliding rod. A chute corresponding to the first sliding rod is formed in the linkage rod. The linkage rod is slidably connected to the first limiting block, and a chute corresponding to the first limiting block is formed in the linkage rod. And two groups of the linkage rods are symmetrically arranged on the outer wall of the first limiting block. The first limiting block slides in the first limiting groove.

[0023] By adopting the above technical solution, it is ensured that the first limiting block slides more smoothly under the drive of the linkage rod, and at the same time, the linkage rod can smoothly drive the first limiting block to slide in the first limiting groove.

[0024] Further, the linkage block is fixedly connected to the second sliding rod, and the outer wall of the linkage block is rotatably connected to the turbine. The linkage block is located on the outer wall of the other end of the transmission rod. One end of the first spring is in contact with the inner wall of the first telescopic rod, and the other end is in contact with the end of the second telescopic rod. The cross section of the second telescopic rod is designed in a rectangular structure.

[0025] By adopting the above technical solution, it is ensured that the linkage block can be smoothly driven to move in the main body of the assembly device through the transmission of the first telescopic rod, and then the first limiting block can smoothly start to move on the outer wall of the guiding block.

[0026] Further, the transmission assembly includes a first transmission gear, and the first transmission gear is slidably connected to the main body of the assembly device.

[0033] By adopting the above technical solution, it is ensured that while the hot melt head works smoothly through the deformation of the elastic member, the space between the protective housing and the dust-proof net is limited, avoiding the adhesion between the dust-proof net and the hot melt head.

[0034] In summary, the present invention mainly has the following beneficial effects:

[0035] 1. Through the cooperation of the driving component and the adjustment component, the present invention drives the worm to rotate inside the assembly device main body through the driving of the braking groove, and at the same time drives the turbine to rotate inside the assembly device main body, so that the first adjustment column and the first limiting block can be smoothly adjusted freely inside the assembly device main body, so that the assembly device main body can adapt to the assembly of dust-proof nets of different sizes.

[0036] 2. Through the cooperation of the clamping assembly and the linkage device, when the user needs to assemble the dust-proof net, the first limiting block is driven by the first sliding rod to move within the main body of the assembly device, overlapping and stacking the dust-proof net and the protective housing, and at the same time restricting the protective housing to prevent movement during the hot melt welding process, thereby making the use of the main body of the assembly device more efficient.

[0037] 3. Through the transmission assembly and the second adjustment assembly, when the user adjusts the main body of the assembly device, with the further cooperation of the linkage device, only one braking is required to install the corresponding hot melt head and adjust the clamping device through the second adjustment column, thereby improving the use efficiency of the device. At the same time, due to the setting of the second adjustment assembly, the center of the hot melt head and the dust-proof net body are kept overlapping, so that the welding head can weld the dust-proof net more accurately during operation.

[0038] 4. Through the setting of the limiting device, the restriction of the protective housing is successfully achieved through the deformation of the elastic member, thereby preventing the dust-proof net and the welding head from sticking during the extrusion process, and avoiding the dust-proof net and the welding head from contacting for a long time, resulting in damage to the dust-proof net due to overheating.

Detailed implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0050] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0051] The present invention provides an adjustable dust-proof net assembly device, mainly to solve the problem that the existing main body 10 of the assembly device cannot use dust-proof nets of different sizes. The core innovation point is that by moving the first adjusting column 21, the user can quickly adjust the position of the first limiting block 31, so that the main body 10 of the assembly device can adapt to different dust-proof nets, as well as related unique structural designs.

[0052] An adjustable dust-proof net assembly device, as Figure 1 - Figure 9 shown, includes the main body 10 of the assembly device, the first adjusting column 21, and the hot press head mounting main body 70. A driving assembly and a quick-release assembly for moving the first adjusting column 21 are installed in the main body 10 of the assembly device. The driving assembly includes a turbine 11 and a worm 12. The first adjusting column 21 is slidably installed in the turbine 11, and an adjusting assembly for moving the first adjusting column 21 is installed in the turbine 11. The first limiting block 31 is fixedly installed at the end of the first adjusting column 21, and a clamping assembly for driving the first limiting block 31 is installed on the outer wall of the first limiting block 31;

[0053] A first adjusting column 21 is slidably installed inside the turbine 11. The turbine 11 is rotatably connected to the main body 10 of the assembling device. The worm 12 is engaged with the turbine 11. A braking groove 13 is formed at the end of the worm 12, and the braking groove 13 is located at the end of the worm 12 away from the turbine 11. The worm 12 is rotatably connected to the main body 10 of the assembling device. By means of the braking groove 13, the worm 12 can be smoothly driven to rotate, and then the turbine 11 starts to rotate inside the main body 10 of the assembling device, ensuring that the user can smoothly drive the turbine 11 to rotate inside the main body 10 of the assembling device through the braking groove 13.

[0054] In this embodiment, the further adjusting assembly further includes a first guiding groove 22 and a first limiting groove 23. The first guiding groove 22 is formed inside the turbine 11, and the first guiding groove 22 is designed in an arc-shaped structure. A plurality of groups of the first guiding grooves 22 are arranged at equal angles inside the turbine 11. The first adjusting column 21 slides inside the first guiding groove 22. A first limiting groove 23 is formed inside the main body 10 of the assembling device, and the first limiting groove 23 is designed in a rectangular structure. A plurality of groups of the first limiting grooves 23 are arranged at equal angles inside the main body 10 of the assembling device. Through the limitation of the first guiding groove 22 and the first limiting groove 23, the first adjusting column 21 moves more smoothly inside the main body 10 of the assembling device, enabling the user to simultaneously adjust the positions of multiple groups of the first adjusting columns 21, ensuring that when the turbine 11 starts to rotate, the first adjusting columns 21 always maintain concentric motion.

[0055] Exemplarily, the clamping assembly further includes a linkage rod 33, a second sliding rod 35 and a second limiting block 36. The second limiting block 36 is slidably connected to the main body 10 of the assembling device. The end of the second limiting block 36 is rotatably connected to the linkage rod 33, and the second limiting block 36 is located inside the first limiting groove 23. One end of the linkage rod 33 is rotatably connected to the first limiting block 31, and the other end of the linkage rod 33 is rotatably connected to the first sliding rod 34. Under the limitation of the second limiting block 36, the first limiting block 31 is driven to start moving inside the first limiting groove 23 by the rotation of the first sliding rod 34. A guiding block 32 is slidably connected to the end of the first limiting block 31, and the guiding block 32 is rotatably connected to the first adjusting column 21. The first sliding rod 34 is slidably connected to the second sliding rod 35, ensuring that the first limiting block 31 can smoothly limit the dust-proof net and the protective housing through the drive of the first sliding rod 34, and at the same time, the user can smoothly stack and clamp and limit the protective housing and the dust-proof net when using the main body 10 of the assembling device.

[0056] In this embodiment, the linkage rod 33 is designed in an L-shaped structure, and the linkage rod 33 is slidably connected to the first slide rod 34. A chute corresponding to the first slide rod 34 is provided in the linkage rod 33. The linkage rod 33 is slidably connected to the first limiting block 31, and a chute corresponding to the first limiting block 31 is provided in the linkage rod 33. Due to the limitation of the second limiting block 36, when the linkage rod 33 starts to rotate within the assembly device main body 10, one end of the linkage rod 33 rotates and starts to slide on the outer wall of the first slide rod 34, and the other end of the linkage rod 33 rotates and starts to slide on the outer wall of the first limiting block 31. Two groups of the linkage rod 33 are symmetrically arranged on the outer wall of the first limiting block 31. The first limiting block 31 slides within the first limiting groove 23, ensuring that the first limiting block 31 slides more smoothly under the drive of the linkage rod 33. At the same time, the linkage rod 33 can smoothly drive the first limiting block 31 to slide within the first limiting groove 23.

[0057] The linkage device in this embodiment includes a linkage block 41. A transmission rod 42 is fixedly installed on the outer wall of the linkage block 41. One end of the transmission rod 42 is rotatably installed with a first telescopic rod 43. A first spring 44 is installed within the first telescopic rod 43. A second telescopic rod 45 is slidably installed within the first telescopic rod 43. The linkage block 41 is fixedly connected to the second slide rod 35. The outer wall of the linkage block 41 is rotatably connected to the turbine 11. The turbine 11 rotates within the assembly device main body 10, and at the same time keeps the linkage block 41 stationary within the assembly device main body 10. The turbine 11 rotates within the assembly device main body 10. The linkage block 41 is located on the outer wall of the other end of the transmission rod 42. One end of the first spring 44 abuts against the inner wall of the first telescopic rod 43, and the other end abuts against the end of the second telescopic rod 45. The cross-section of the second telescopic rod 45 is designed in a rectangular structure. When the second telescopic rod 45 starts to slide within the first telescopic rod 43, under the limitation of the first spring 44, the first telescopic rod 43 drives the transmission rod 42 to drive the linkage block 41 to move within the assembly device main body 10. When the second telescopic rod 45 starts to move, it is ensured that the linkage block 41 can be smoothly driven to start moving within the assembly device main body 10 through the transmission of the first telescopic rod 43, thereby enabling the first limiting block 31 to smoothly start moving on the outer wall of the guiding block 32.

[0058] The further transmission assembly of this embodiment includes a first transmission gear 51, a transmission block 52 and a second transmission gear 53. The first transmission gear 51 is slidably connected to the main body 10 of the assembly device. The cross-section of the first transmission gear 51 is designed as a circular structure, enabling the first transmission gear 51 to slide smoothly within the main body 10 of the assembly device. At the same time, the first transmission gear 51 can rotate within the main body 10 of the assembly device, and the first transmission gear 51 is fixedly connected to the transmission rod 42. One end of the transmission block 52 is fixedly connected to the second telescopic rod 45, and the other end of the transmission block 52 is fixedly connected to the second transmission gear 53. The first transmission gear 51 meshes with the turbine 11. Through the rotation of the first transmission gear 51, the first telescopic rod 43 is driven to rotate. At this time, due to the rectangular design of the second telescopic rod 45, it is ensured that while the first transmission gear 51 slides within the main body 10 of the assembly device, it can also rotate simultaneously under the rotation of the turbine 11, thereby driving the second adjustment assembly to move simultaneously.

[0059] It should be noted that the second adjustment assembly includes a second adjustment gear 61 and a second guide groove 62. A second guide groove 62 is formed in the second adjustment gear 61, and a second adjustment column 63 is slidably installed in the second guide groove 62. The second guide groove 62 is designed as an arc-shaped structure, and multiple groups of second guide grooves 62 are arranged at equal angles within the second adjustment gear 61. The second adjustment gear 61 meshes with the second transmission gear 53. The rotation of the first telescopic rod 43 drives the second transmission gear 53 to start rotating within the main body 70 for installing the hot press head through the second telescopic rod 45, thereby driving the second transmission gear 53 to rotate simultaneously and realizing the rotation of the second adjustment gear 61. At this time, due to the limitation of the second limiting groove 71, the position of the second adjustment column 63 can be smoothly changed, ensuring that the position of the second adjustment column 63 can be smoothly adjusted through the rotation of the second transmission gear 53, thereby realizing the installation of different hot melt heads.

[0060] In this embodiment, the hot press head mounting body 70 is fixedly connected to the assembly device body 10. When the assembly device body 10 starts to operate, the hot press head mounting body 70 starts to move within the assembly device body 10. A second limiting groove 71 is formed in the hot press head mounting body 70, and the second adjusting column 63 is slidably connected to the second limiting groove 71, so that the second adjusting column 63 can smoothly move within the hot press head mounting body 70. The horizontal plane at the top of the second adjusting column 63 is higher than the horizontal plane at the bottom of the hot press head mounting body 70. The transmission block 52 is rotatably connected to the hot press head mounting body 70. The second telescopic rod 45 starts to rotate within the assembly device body 10, and at the same time drives the transmission block 52 to start rotating within the hot press head mounting body 70, thereby driving the second transmission gear 53 to start rotating, ensuring that the second telescopic rod 45 can smoothly drive the second transmission gear 53 to rotate through the transmission block 52. At the same time, under the restriction of the second limiting groove 71, the movement of the second adjusting column 63 is smoother. At the same time, through the setting of the hot press head mounting body 70, the assembly device body 10 can better drive the hot melt head to move.

[0061] It should be emphasized that the limiting device includes an elastic member 81, a slider 82, a guiding column 83 and a guiding groove 84. One end of the elastic member 81 is rotatably connected to the first limiting block 31, and the other end of the elastic member 81 is fixedly connected to the guiding column 83. The guiding column 83 is slidably connected to the slider 82. The elastic member 81 is designed in an arc structure. When the hot melt head contacts the elastic member 81, under the action of the assembly device body 10, the elastic member 81 starts to deform. The cross-section of the guiding column 83 is designed in a rectangular structure, and two groups of guiding columns 83 are symmetrically arranged within the first limiting block 31. Two groups of sliders 82 are symmetrically arranged on the side of the elastic member 81. Then, it drives the guiding column 83 to start sliding within the guiding groove 84, and at the same time the slider 82 starts to rotate within the guiding column 83, ensuring that while the hot melt head works smoothly through the deformation of the elastic member 81, it restricts between the protective housing and the dust-proof net, and prevents the dust-proof net from sticking to the hot melt head.

[0062] The working principle of the present invention is as follows: The user drives the worm 12 to start rotating within the assembly device main body 10 through the braking groove 13. At this time, the rotation of the worm 12 drives the turbine 11 to start rotating within the assembly device main body 10. At this time, under the guidance of the first guiding groove 22, the first adjusting column 21 starts to move within the assembly device main body 10, thereby driving the first limiting block 31 to start moving within the assembly device main body 10. At this time, the second limiting block 36 also moves within the assembly device main body 10. At the same time, due to the limitation of the first limiting groove 23, multiple groups of first adjusting columns 21 start to move within the assembly device main body 10 simultaneously, driving multiple groups of first limiting blocks 31 to slide within the first limiting groove 23. At this time, due to the limitation of the second limiting block 36, the first limiting block 31 pulls the first sliding rod 34 to start sliding on the outer wall of the second sliding rod 35 through the linkage rod 33. Multiple groups of first limiting blocks 31 connected to the linkage block 41 start to move within 1O, thereby achieving the purpose of adjusting the first adjusting column 21 and the first limiting block 31;

[0063] At the same time, through the setting of the first transmission gear 51, when the turbine 11 starts to rotate, under the drive of the turbine 11, the first transmission gear 51 starts to rotate simultaneously, thereby driving the first telescopic rod 43 to rotate simultaneously at the end of the transmission rod 42. At this time, due to the rectangular design of the second telescopic rod 45, under the limitation of the first telescopic rod 43, the second telescopic rod 45 starts to rotate simultaneously, thereby driving the second transmission gear 53 at the other end of the second telescopic rod 45 to start rotating within the hot press head installation main body 70. At the same time, due to the rotation of the transmission block 52, the second transmission gear 53 starts to rotate simultaneously, thereby driving the second adjusting gear 61 to start rotating within the hot press head installation main body 70. At this time, due to the limitation of the second limiting groove 71, the second adjusting column 63 starts to move within the hot press head installation main body 70, so that the user can simultaneously change the position of the second adjusting column 63 according to the installation requirements of the hot melt head by rotating the turbine 11. Therefore, when the user adjusts the assembly device main body 10, it is not necessary to adjust the assembly device main body 10 multiple times;

[0064] When the user needs to use the main body 10 of the assembly device, after the user adjusts the position of the first limiting block 31, the user places the dust-proof net and the protective housing between multiple groups of first limiting blocks 31 at the same time. At this time, the user can start the main body 10 of the assembly device, so that the hot press head mounting main body 70 starts to move inside the main body 10 of the assembly device, and at the same time drives the transmission block 52 to move inside the main body 10 of the assembly device. Furthermore, the transmission block 52 drives the second telescopic rod 45 to start sliding inside the first telescopic rod 43. At this time, due to the limitation of the first spring 44, the first telescopic rod 43 transmits the force of the second telescopic rod 45 to the first transmission gear 51. At this time, the first transmission gear 51 starts to slide in 1O, and at the same time the first transmission gear 51 still meshes with the turbine 11. At this time, as the transmission block 52 moves, it drives the first telescopic rod 43 to start sliding inside the main body 10 of the assembly device, and at the same time drives the linkage block 41 to start sliding inside the main body 10 of the assembly device through the transmission rod 42. Furthermore, the linkage rod 33 is driven to start rotating inside the main body 10 of the assembly device through the second sliding rod 35 and the first sliding rod 34. At this time, due to the limitation of the second limiting block 36, the linkage rod 33 drives the first limiting block 31 to start sliding inside the guiding block 32 and at the same time sliding inside the first limiting groove 23. With the linkage of the linkage block 41, multiple groups of first limiting blocks 31 start to move towards the same center at the same time inside the first limiting groove 23. At this time, driven by the movement of multiple groups of first limiting blocks 31, the dust-proof net and the protective housing overlap each other. At the same time, with the continuous movement of the transmission block 52, when the hot melt head is in contact with the outer wall of the elastic member 81, as the hot press head mounting main body 70 moves further, the elastic member 81 starts to deform, and then drives the guiding column 83 to start sliding inside the guiding groove 84, and at the same time the slider 82 starts to rotate inside the guiding column 83. At this time, the elastic member 81 completely enters the first limiting block 31, and the first limiting block 31 and the elastic member 81 inside the first limiting block 31 start to limit the protective housing and the dust-proof net;

[0065] When the first limiting block 31 starts to preliminarily limit the protective housing, as the transmission block 52 is further pressed down, the second telescopic rod 45 starts to squeeze the first spring 44 until the hot melt head starts to press-weld the dust-proof net and the protective housing, and then the hot press head mounting body 70 stops moving. At this time, the second telescopic rod 45 stops squeezing the first spring 44, and at the same time, the second telescopic rod 45 remains stable within the first telescopic rod 43. When a hot melt welding operation ends, similarly, the hot press head mounting body 70 starts to move within the assembly device main body 10. As the hot melt head moves on the outer wall of the elastic member 81, at this time, the elastic member 81 starts to reset under the action of its own stress. At the same time, it drives the second telescopic rod 45 to move within the first telescopic rod 43, and at the same time, the first spring 44 starts to reset. When the hot press head mounting body 70 moves to the initial position, the first telescopic rod 43 drives the transmission rod 42 to reset at the same time, and then drives the linkage block 41 to drive the first sliding rod 34 and the second sliding rod 35 to reset, thereby starting to limit the dust-proof net main body and the dust-proof net, avoiding the dust-proof net from always contacting the hot melt head. When the elastic member 81 no longer contacts the hot melt head, by the rotation of the first sliding rod 34, it drives the first limiting block 31 to no longer limit the dust-proof net protective housing. At this time, the user can remove the assembled dust-proof net.
