Description

Technical Field

[0001] This utility model relates to the field of smart glasses manufacturing equipment, specifically a multi-station pressing device for online frames and dustproof nets. Background Technology

[0002] Smart glasses have speakers that can emit sound. Since the speakers have mesh openings, a dustproof mesh is needed to prevent dust accumulation and blockage. The dustproof mesh has an adhesive backing layer and is pre-installed on the speaker opening of the frame, then pressed together using a pressing device. Existing devices for attaching dustproof meshes to 3C products are too simple in structure, have low automation, and are inefficient for assembling dustproof meshes on batches of products.

[0003] For example, Chinese patent CN206658376U discloses a dustproof net pressure-holding device, including a base plate, a first cylinder arranged along the side of the base plate, and a second cylinder arranged perpendicular to the side of the base plate. A fixed seat is connected to the output end of the first cylinder, and a pressure head structure is connected to the output end of the second cylinder, with the pressure head structure located above the moving direction of the fixed seat. It also includes a controller, with a solenoid valve connected to the first cylinder and a solenoid valve connected to the second cylinder electrically connected to the controller. This dustproof net pressure-holding device uses the first cylinder to move the fixed seat towards one side of the second cylinder, and the second cylinder to press the pressure head structure onto the dustproof net, holding the pressure for a certain period to ensure the dustproof net is firmly adhered to the product shell. However, this method is only suitable for offline pressing of a single product and is inefficient.

[0004] Therefore, it is necessary to provide an online multi-station pressing device for eyeglass frames and dustproof nets. Utility Model Content

[0005] This utility model provides an online multi-station pressing device for eyeglass frames and dustproof nets, which effectively solves the problem of low pressing efficiency between eyeglass frames and dustproof nets.

[0006] The technical solution adopted in this utility model is:

[0007] An online multi-station pressing device for mirror frames and dustproof nets includes a frame and several fixtures, a multi-station staggered conveyor line mounted on the frame, and at least two pressing mechanisms arranged along the X-axis on the frame. The multi-station staggered conveyor line includes several fixed conveyor mechanisms with the X-axis as the conveying direction, several Y-axis drive mechanisms corresponding one-to-one with the pressing mechanisms, and several movable conveyor mechanisms with the X-axis as the conveying direction. The movable conveyor mechanisms are fixedly mounted on the Y-axis drive mechanisms, and each Y-axis drive mechanism has two movable conveyor mechanisms arranged along the Y-axis. The movable conveying mechanism can be connected to the conveying mechanism to form a multi-station staggered conveying line.

The pressing mechanism includes a gantry frame set on the machine frame, a first linear guide rail set on the gantry frame along the X direction, a transverse frame slidably set on the first linear guide rail, a first linear module fixedly set on the gantry frame for driving the transverse frame to slide along the first linear guide rail, and two pressing modules arranged on the transverse frame along the X direction. The fixture is provided with two material discharge slots.

[0008] Furthermore, the pressing module includes a second linear module vertically mounted on the mounting plate, a floating connecting frame fixedly mounted on the output end of the second linear module, and a clamping assembly mounted on the lower end face of the floating connecting frame.

[0009] Furthermore, the floating connecting frame includes a first plate disposed at the output end of the second linear module, several linear bearings vertically disposed on the first plate, guide pillars sleeved on the linear bearings, a second plate connected to the lower ends of several guide pillars, and several sets of clamping assemblies disposed on the lower end face of the second plate for clamping the product. The clamping assembly includes a gripper cylinder disposed on the lower end face of the second plate and two clamping plates driven by the gripper cylinder.

[0010] Furthermore, the Y-axis drive mechanism drives the movable conveyor mechanism to move along the Y-axis direction, so that the two movable conveyor mechanisms on the same Y-axis drive mechanism alternately dock with the fixed conveyor mechanism.

[0011] Furthermore, both the fixed conveying mechanism and the movable conveying mechanism include a base, a second linear guide rail arranged along the Y-axis on the base, a fixed plate fixedly arranged on the base and located at one end of the second linear guide rail, a movable plate slidably arranged on the second linear guide rail, a first shaft fixedly connected to the fixed plate and the base at both ends respectively, a locking component fixedly connected to the movable plate for locking with the first shaft, belt conveyor lines respectively arranged on the movable plate and the fixed plate, and a drive assembly. The first shaft has a scale line arranged along the axial direction, and the drive assembly is used to drive the two belt conveyor lines to move synchronously.

[0012] Furthermore, the belt conveyor line includes a drive pulley, a flat belt, and several driven pulleys. The flat belt is connected to the drive pulley and the driven pulleys. The drive pulley is coaxially provided with a prismatic hole. The drive assembly includes a motor mounted on a base, a drive pulley mounted on the motor shaft, a prism coaxially connected to the drive pulley through the prismatic hole, a cylinder coaxially fixedly connected to one end of the prism, a ball bearing, a driven pulley coaxially fixedly mounted on the cylinder, and a synchronous belt connected to the drive pulley and the driven pulleys. The ball bearing is mounted on the base, and the inner ring of the ball bearing is connected to the cylinder. The drive pulley mounted on the movable plate can move along the axial direction of the prism.

[0013] Furthermore, the movable conveying mechanism includes a lifting component mounted on the base for ejecting the fixture from the belt conveyor line, a stopping component for stopping the fixture in the belt conveyor line, and a return conveyor line is also mounted on the frame.

[0014] The beneficial effects of the utility model are as follows: by setting up a multi-station staggered conveyor line, the fixture can be staggered and conveyed, which improves the efficiency of product pressing. At the same time, the structural design of the pressing mechanism and the fixture can simultaneously enable two pressing modules of one pressing mechanism to press two products, further improving efficiency.

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 , Figure 2 and Figure 3As shown in the embodiment of this application, an online multi-station pressing device for mirror frames and dustproof nets includes a frame 1, a gantry frame 10 mounted on the frame 1, and several fixtures 2. It also includes a multi-station staggered conveyor line 3 mounted on the frame 1 and at least two pressing mechanisms 4 arranged along the X-axis on the gantry frame 10. The multi-station staggered conveyor line 3 includes several fixed conveyor mechanisms 31 that convey the fixtures 2 along the X-axis, several Y-axis drive mechanisms 32 corresponding one-to-one with the pressing mechanisms 4, and several movable conveyor mechanisms 33 that convey the fixtures 2 along the X-axis. The movable conveyor mechanisms 33 are fixedly mounted on the Y-axis drive mechanisms 32. Each Y-axis drive mechanism 33... Two movable conveying mechanisms 33 are arranged along the Y-axis direction on the shaft drive mechanism 32. The two movable conveying mechanisms 33 can be docked with adjacent fixed conveying mechanisms 31 to form a multi-station staggered conveying line 3. At least one fixed conveying mechanism 31 is arranged between the two Y-axis drive mechanisms 32. The pressing mechanism 4 includes a first linear guide rail 42 arranged along the X-direction on the gantry frame 10, a transverse frame 43 slidably arranged on the first linear guide rail 42, a first linear module 44 fixedly arranged on the gantry frame 10 for driving the transverse frame 43 to slide along the first linear guide rail 42, and two pressing modules 41 arranged along the X-direction on the transverse frame 43. The fixture 2 is provided with two material discharge slots.

[0025] It should be noted that, as Figure 7 As shown, a mounting port 200 for installing a dustproof net is provided on each of the two side walls of the housing 100 of the mirror frame. This application uses a PLC control system to control the automatic operation of the pressing mechanism 4 and the multi-station staggered conveyor line 3.

[0026] In practical use, the device of this application can be connected to the previous and subsequent stations for pressing the frame and dustproof net together, so that the fixture 2 is automatically conveyed from the previous station to the fixed conveying mechanism 31 at one end of the device and flows out along the fixed conveying mechanism 31 at the other end of the device. The two movable conveying mechanisms 33 are driven synchronously along the Y-axis by the Y-axis drive mechanism 32, so that one of the movable conveying mechanisms 33 is connected to the adjacent fixed conveying mechanism 31 for conveying the fixture 2. When one movable conveying mechanism 33 is connected to the fixed conveying mechanism 31, the other movable conveying mechanism 33 is connected to the pressing mechanism 4. When the other pressing mechanism 4 is connected to the fixed conveying mechanism 31, the movable conveying mechanism 33 that was originally connected to the fixed conveying mechanism 31 moves away from the pressing mechanism 4. The fixture 2 is conveyed to the corresponding pressing mechanism 4 through the multi-station staggered conveyor line 3. The first linear module 44 drives the pressing module 41 to clamp the product, so that the dustproof net is bonded to the shell 100 of the frame.

[0027] In the above design, the multi-station staggered conveyor line 3 of this application is designed online, allowing the device to be directly embedded in the production line of the picture frame and linked with other equipment such as conveyor belts, robotic arms, and inspection stations, without the need for manual intervention or separate workpiece handling. By setting up the multi-station staggered conveyor line 3, staggered conveying of the fixture 2 can be achieved, improving the efficiency of product pressing. At the same time, the structural design of the pressing mechanism 4 and the fixture 2 can simultaneously enable the two pressing modules 41 of one pressing mechanism 4 to press two products, further improving efficiency.

[0028] Specifically: such as Figure 4 As shown, the pressing module 41 includes a second linear module 411 vertically mounted on the mounting plate, a floating connecting frame 413 fixedly mounted on the output end of the second linear module 411, and two clamping assemblies 414 mounted on the lower end face of the floating connecting frame 413.

[0029] In actual use, after the pressing module 41 is driven above the fixture 2 by the first linear module 44, the second linear module 411 drives the floating connecting frame 413 to move downwards, causing the lower end face of the fixture 2 of the clamping assembly 414 to abut against each other. Under the continuous drive of the second linear module 411, the floating connecting frame 413 is compressed. Then, the two clamping assemblies 414 clamp the two side walls of the housing 100, pressing the dustproof net pre-installed on the housing 100 onto the housing 100 and covering the mounting opening 200. Then, the clamping pressing module 41 is released and reset.

[0030] In the above design, the structural design and specific implementation of the pressing module 41 can effectively achieve precise pressing of the dustproof net and the shell 100, and the floating connecting frame 413 will not cause the clamping component 414 to damage the upper surface of the fixture 2 or cause damage to the clamping component 414.

[0031] Specifically: such as Figure 5 As shown, the floating connecting frame 413 includes a first plate 4131 disposed at the output end of the second linear module 411, several linear bearings 4132 vertically disposed on the first plate 4131, guide posts 4133 sleeved on the linear bearings 4132, springs sleeved on the guide posts 4133, and a second plate 4134 connecting the lower ends of the several guide posts 4133. The two ends of the springs abut against the second plate 4134 and the linear bearings 4132 respectively. The clamping assembly 414 includes a gripper cylinder 4135 disposed on the lower end face of the second plate 4134 and two clamping plates 4136 driven by the gripper cylinder 4135.

[0032] In actual use, after the lower end of the clamping plate 4136 contacts the fixture 2, it continues to move downward under the drive of the second linear module 411, causing the spring to compress and the guide post 4133 to slide relative to the linear bearing 4132, thus reducing the distance between the first plate 4131 and the second plate 4134. When the second linear module 411 drives the floating connecting frame 413 to move upward, causing the clamping plate 4136 to disengage from the end face of the fixture 2, the spring gradually returns to its original position, restoring the distance between the first plate 4131 and the second plate 4134.

[0033] In the above design, the structural design and specific implementation of the floating connecting frame 413 facilitate the reduction of the impact of the clamping plate 4136 on the fixture 2, achieve buffer protection, and avoid damage to the clamping plate 4136 and the fixture 2.

[0034] Specifically: the Y-axis drive mechanism 32 drives the movable conveying mechanism 33 to move along the Y-axis direction, so that the two movable conveying mechanisms 33 on the same Y-axis drive mechanism 32 alternately dock with the fixed conveying mechanism 31.

[0035] Specifically: such as Figure 2 and Figure 6 As shown, both the fixed conveying mechanism 31 and the movable conveying mechanism 33 include a base 311, a second linear guide rail 312 arranged along the Y-axis direction on the base 311, a fixed plate 313 fixedly arranged on the base 311 and located at one end of the second linear guide rail 312, a movable plate 314 slidably arranged on the second linear guide rail 312, a first shaft 315 whose two ends are fixedly connected to the fixed plate 313 and the base 311 respectively, a locking member 316 fixedly connected to the movable plate 314 for locking with the first shaft 315, belt conveyor lines 317 respectively arranged on the movable plate 314 and the fixed plate 313, and a drive assembly 318. The first shaft 315 is provided with a scale line along the axial direction, and the drive assembly 318 is used to drive the two belt conveyor lines 317 to move synchronously.

[0036] In actual use, when it is necessary to adjust the width (Y-axis dimension) of the entire conveyor line, the drive assembly 318 drives the two belt conveyor lines 317 to move synchronously. The lower ends of both sides of the fixture 2 contact the two belt conveyor lines 317 respectively, and the synchronous transmission of the two belt conveyor lines 317 realizes the conveying of the fixture 2. When the size of the fixture 2 changes and the spacing of the two belt conveyor lines 317 needs to be adjusted: loosen the locking piece 316, push the movable plate 314 along the axial direction of the first axis 315, so that the movable plate 314 drives the belt conveyor lines 317 set on the movable plate 314 to move synchronously as it moves along the fifth linear guide rail, so that the spacing of the two belt conveyor lines 317 is adjusted to the appropriate position of the fixture 2. Then, the locking piece 316 is tightened again to fix the position of the movable plate 314.

[0037] In the above design, the structural design and specific implementation of the fixed conveying mechanism 31 and the movable conveying mechanism 33 facilitate the rapid adjustment of the width of the entire conveying line, enabling the conveying of jigs 2 of different sizes.

[0038] Specifically: such as Figure 6 As shown, the belt conveyor 317 includes a drive pulley 171, a flat belt, and several driven pulleys. The flat belt is driven by the drive pulley 171 and the driven pulleys. The drive pulley 171 is coaxially provided with a prismatic hole. The drive assembly 318 includes a motor 185 mounted on a base 311, a drive pulley 183 mounted on the shaft of the motor 185, a prism 184 coaxially connected to the drive pulley 171 through the prismatic hole, a cylinder coaxially fixedly connected to one end of the prism 184, a ball bearing, a driven pulley 181 coaxially fixedly mounted on the cylinder, and a synchronous belt 182 driven by the drive pulley 183 and the driven pulley 181. The ball bearing is mounted on the base 311 and its inner ring is connected to the cylinder. The drive pulley 171 mounted on the movable plate 314 can move axially along the prism 184.

[0039] In actual use, the motor 185 drives the drive pulley 183 to rotate, and with the cooperation of the synchronous belt 182, the driven pulley 181 rotates. Thus, the driven pulley 181 drives the cylinder and prism 184 to rotate synchronously, and the prism 184 drives the drive wheel 171 to rotate. With the cooperation of the driven wheel, the flat belt rotates.

[0040] In the above design, the structural design and specific implementation of the belt conveyor 317 can effectively realize the transmission of the flat belt.

[0041] Specifically: such as Figure 6 As shown, the movable conveying mechanism 33 includes a lifting component 331 mounted on the base 311 for ejecting the fixture 2 from the belt conveyor line 317, and a stopping component 332 for stopping the fixture 2 in the belt conveyor line 317. A return conveyor line 9 is also mounted on the frame 1.

[0042] In actual use, when it is necessary to lift the conveying fixture 2, the fixture 2 is first stopped by the stop component 332, and then the lifting component 331 lifts the fixture 2 from below. The return conveyor line 9 is used to return the subsequently unloaded fixture 2.

[0043] In the above design, the structural design and specific implementation of the movable conveying mechanism 33 can effectively lift the fixture 2, so that the fixture 2 can cooperate with the pressing mechanism 4 to press the product in the lifted state.

[0044] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
