Description

Technical Field

[0001] This invention relates to the field of dispensing devices, specifically a three-axis dispensing device and method for the hinges and wiring of an online mirror frame. Background Technology

[0002] The smart eyeglass frame consists of multiple components and requires the installation of electrical modules and connecting cables within the frame. To ensure a secure connection between the various modules during use, adhesive must be applied to and cured onto the cables and the frame's hinges. Existing adhesive application devices employ adhesive application mechanisms and pressure-holding mechanisms on both sides of the conveyor line. Since adhesive application takes time, the conveyor line must stop moving during this process, slowing down the overall adhesive application cycle and reducing work efficiency.

[0003] For example, Chinese patent CN112076953A discloses a motor rotor dispensing machine, including a frame with a first dispensing area and a second dispensing area. The first dispensing area has a rotor conveyor line with a three-section design. A preheating device and a material transfer robot are respectively installed at both ends of the rotor conveyor line. A first dispensing assembly is located on one side and / or above the middle section of the rotor conveyor line. The first dispensing assembly includes one or more combinations of a wire insulation dispensing mechanism, a fan blade dispensing mechanism, and a neck dispensing mechanism. The second dispensing area has a multi-station slot dispensing mechanism and a material unloading and storage mechanism. In this motor rotor dispensing machine, dispensing is performed through various mechanisms on both sides of the rotor conveyor line. The conveyor line needs to switch between conveying and stopping at a certain rhythm, reducing work efficiency.

[0004] For example, Chinese patent CN110801995B discloses an automated dispensing machine. This machine includes a worktable with a first and second transfer mechanism mounted on it. The worktable also has a pick-up station and a processing station. The first transfer mechanism transfers a lens tray from the pick-up station to the processing station, and the second transfer mechanism transfers a product tray from the pick-up station to the processing station. The worktable also includes a lens loading mechanism and a dispensing mechanism. The lens loading mechanism transfers lenses from the lens tray to the product trays on either side, and the dispensing mechanism connects the lenses and the products together. This automated dispensing machine improves efficiency by incorporating multiple transfer mechanisms and two dispensing mechanisms; however, this method still cannot achieve continuous product supply.

[0005] Therefore, it is necessary to provide a three-axis dispensing device and dispensing method for the hinges and wiring of an online eyeglass frame. Summary of the Invention

[0006] This invention provides a three-axis dispensing device and method for the hinge and wiring of an online eyeglass frame, which effectively solves the problem of low dispensing efficiency for eyeglass frames.

[0007] The technical solution adopted in this invention is:

[0008] A three-axis dispensing device for hinges and cabling of an online eyeglass frame includes a frame and several fixtures. It also includes at least two dispensing mechanisms arranged along the X direction on the frame, staggered connecting lines arranged on the frame corresponding to the dispensing mechanisms, and several conveying mechanisms arranged along the X direction on the frame. The staggered connecting lines include at least two streamlined mechanisms arranged along the Y direction, and a first drive mechanism arranged on the frame for driving the two streamlined mechanisms to move synchronously along the Y-axis. The conveying mechanisms and one of the streamlined mechanisms form a conveying line.

[0009] Furthermore, the first drive mechanism drives one of the streamline mechanisms and the conveying mechanism to form a conveyor line to transport the fixture, so that the product fixed in the fixture in the other streamline mechanism is dispensed with glue. After the dispensing is completed, the first drive mechanism drives the other streamline mechanism and the conveying mechanism to form a conveyor line to send out the fixture with the dispensed product, and then receives the fixture carrying the dispensed product again.

[0010] Furthermore, the first drive mechanism includes a mounting plate fixedly mounted on the frame, a first linear guide rail mounted on the frame along the Y-axis, a support plate slidably mounted on the first linear guide rail, and a first linear module fixedly mounted on the mounting plate for driving the support plate to slide along the first linear guide rail. The streamlined mechanism is fixedly mounted on the upper surface of the support plate.

[0011] Furthermore, both the streamlined mechanism and the 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 streamlined mechanism also includes a backstop, a stop assembly, and a lifting assembly mounted on the base. The stop assembly includes a first vertical plate mounted on the base, a third linear guide rail mounted on the first vertical plate, a stop block slidably mounted on the third linear guide rail, and a first cylinder mounted on the base for driving the stop block to rise and fall. The lifting assembly includes a stand mounted on the base, a fourth linear guide rail vertically mounted on the stand, a top material rack slidably mounted on the fourth linear guide rail, and a second cylinder mounted on the base for driving the top material rack to rise and fall.

[0014] Furthermore, the fixture includes a base plate, a support seat on the base plate for supporting the mirror frame, a cover plate hinged to the base plate, a latch connecting the cover plate and the base plate, and two elastic pressure components on both sides of the base plate for lateral pressure on the mirror frame. Each elastic pressure component includes a mounting block on the base, a first pin on the mounting block along the Y-axis, a pressure plate slidably mounted on the first pin, a spring sleeved on the first pin, a second pin on the mounting block along the Z-axis, a knob rotating on the second pin, a third pin on the pressure plate, a metal plate hinged to the third pin, and a magnet on the pressure plate for magnetic connection with the metal plate. The frame is also equipped with two sets of unlocking mechanisms located on the feeding side of the conveyor line. Each unlocking mechanism includes a mounting frame, a third cylinder mounted on the mounting frame, a rotary cylinder at the output end of the third cylinder, and a lever eccentrically mounted at the output end of the rotary cylinder.

[0015] Furthermore, the dispensing mechanism includes a gantry frame mounted on the machine frame, a No. 5 linear guide rail mounted on the gantry frame along the Y-axis, a sliding frame slidably mounted on the No. 5 linear guide rail, a No. 5 linear module fixedly mounted on the gantry frame for driving the sliding frame to slide, a No. 6 linear guide rail mounted on the sliding frame along the X-axis, a transverse frame slidably mounted on the No. 6 linear guide rail, a No. 6 linear module mounted on the sliding frame for driving the transverse frame to move, a No. 7 linear guide rail vertically mounted on the transverse frame, a lifting frame slidably mounted on the No. 7 linear guide rail, an No. 8 linear module fixedly mounted on the transverse frame for driving the lifting frame to move up and down, a dispensing machine mounted on the lifting frame, and a vision inspection module.

[0016] Furthermore, the frame is also equipped with a shelf, on which are mounted a glue-wiping assembly, a needle-aligning assembly, and a glue bucket. The frame is also equipped with a return line located below the conveyor line.

[0017] The three-axis dispensing method uses the three-axis dispensing device for the hinge and wiring of the online frame. One of the two intersecting connecting lines forms a conveyor line with several conveying mechanisms. The fixture is conveyed through the conveyor line, and the dispensing mechanism performs dispensing through the other streamline mechanism of the two intersecting connecting lines in conjunction with the dispensing mechanism.

[0018] Beneficial effects of the invention:

[0019] 1. The device in this application adopts an online design, which is convenient for embedding into the production line of the picture frame and realizes modular application. Through multiple streamline mechanisms and conveying mechanisms, a conveyor line is formed that can continuously transport the fixture, which can ensure that the conveyor line does not stop transporting when the dispensing mechanism dispenses glue to the product in the fixture, thus improving dispensing efficiency.

[0020] 2. Both the streamline mechanism and the conveying mechanism adopt an adjustable spacing design, which allows the working state to be switched by adjusting the spacing of the two belt conveyor lines when adapting to jigs of different sizes. This enables the conveying of jigs of different sizes, which is more convenient and cost-effective compared to replacing the conveyor lines.

[0021] 2. The structural design of the fixture and unlocking mechanism enables automatic pressing of the ribbon cable and hinge after dispensing. The fixture and unlocking structure is simple and compact, does not take up space, and is easy to operate.

[0022] 4. By setting up at least two dispensing mechanisms for dispensing, and forming multiple dispensing stations with a corresponding number of staggered splicing lines, multiple products can be dispensed simultaneously, improving dispensing efficiency. Attached Figure Description

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, the first embodiment provided by the embodiments of this application is a three-axis dispensing device for the hinges and wiring of an online eyeglass frame. It includes a frame 1 and several fixtures 2, and also includes at least two dispensing mechanisms 3 arranged along the X direction on the frame 1, staggered connecting lines 4 arranged on the frame 1 corresponding one-to-one with the dispensing mechanisms 3, and several conveying mechanisms 5 arranged along the X direction on the frame 1. The staggered connecting lines 4 include at least two streamlined mechanisms 41 arranged along the Y direction, and a first drive mechanism 42 arranged on the frame 1 for driving the two streamlined mechanisms 41 to move synchronously along the Y axis. The conveying mechanisms 5 and one of the streamlined mechanisms 41 form a conveying line.

[0034] It should be noted that the frame includes a frame body 100 and a hinge 200 assembled to the end of the frame body 100. The hinge 200 has a notch 201, through which adhesive is dispensed during dispensing. Protrusions 202 are provided on both sides of the notch 201. This application uses a PLC control system to control the dispensing mechanism 3, the staggered connection line 4, and the conveying mechanism 5.

[0035] like Figure 3 As shown, this application connects to the preceding and following processes of the sorting and hinge dispensing via two ends of the conveyor line. This application has two dispensing mechanisms 3 and two corresponding staggered connection lines 4. At least one conveying mechanism 5 is located between the two staggered connection lines. For ease of understanding, the two staggered connection lines 4 are referred to as the first staggered connection line and the second staggered connection line. The two streamlined mechanisms 41 of the first staggered connection line are streamlined mechanism A and streamlined mechanism B, respectively, and the two streamlined mechanisms 41 of the second staggered connection line are streamlined mechanism a and streamlined mechanism b, respectively. In practical use, assuming the first staggered connection line is upstream of the second staggered connection line (fixture 2 is transferred from one side of the first staggered connection line to the other side of the second staggered connection line), the initial state is that streamlined mechanism a and streamlined mechanism A form a conveyor line with conveying mechanism 5, and streamlined mechanism b and streamlined mechanism B are located at the dispensing position, so that the product of fixture 2 in streamlined mechanism b and streamlined mechanism B is dispensed. After the dispensing of the product of fixture 2 in streamlined mechanism b and streamlined mechanism B is completed, the first drive mechanism 42 drives streamlined mechanism b to replace the position of streamlined mechanism a, and streamlined mechanism B replaces streamlined mechanism A. The positions are such that streamlined mechanism b and streamlined mechanism B form a conveyor line with conveyor mechanism 5. At this time, after the dispensing is completed, the fixture 2 is conveyed downstream (the fixture 2 in streamlined mechanism B is conveyed downstream to conveyor mechanism 5 between two intersecting connecting lines 4, and the fixture 2 in streamlined mechanism b is conveyed downstream to conveyor mechanism 5). After streamlined mechanism B and streamlined mechanism b receive the fixture 2 to be dispensed again, they move to the dispensing position under the re-drive of drive mechanism 42. At this time, streamlined mechanism A conveys the fixture 2 carrying the undispensed product, and streamlined mechanism a conveys the fixture 2 after dispensing by streamlined mechanism B.

[0036] In the above design, the device of this application adopts an online design, which is convenient for embedding into the production line of the picture frame and realizes modular application. The design of the staggered connection line 4 and the conveying mechanism 5 enables the fixture 2 carrying the product to be glued to be transported to the downstream dispensing mechanism 3 during dispensing. Compared with the design of the entire conveyor line due to the dispensing braking, this application can maintain the conveying of the conveyor line and improve the dispensing efficiency.

[0037] Specifically: the first drive mechanism 42 drives one of the streamline mechanisms 41 to form a conveyor line with the conveying mechanism 5 to transport the fixture 2, so that the product fixed in the fixture 2 in the other streamline mechanism 41 is dispensed. After the dispensing is completed, the first drive mechanism 42 drives the other streamline mechanism 41 to form a conveyor line with the conveying mechanism 5 to transport the fixture 2 with the dispensed product, and then receives the fixture 2 carrying the dispensed product again.

[0038] Specifically: such as Figure 3 As shown, the first drive mechanism 42 includes a mounting plate 421 fixedly mounted on the frame 1, a first linear guide rail 422 mounted on the frame 1 along the Y-axis, a support plate slidably mounted on the first linear guide rail 422, and a first linear module 423 fixedly mounted on the mounting plate 421 for driving the support plate to slide along the first linear guide rail 422. The streamline mechanism 41 is fixedly mounted on the upper surface of the support plate.

[0039] In actual use, when it is necessary to move the two streamlined mechanisms 41, the first linear module 423 drives the support plate to slide along the first linear guide rail 422, so that the support plate drives the two streamlined mechanisms 41 to move synchronously.

[0040] In the above design, the structural design and specific implementation of the first drive mechanism 42 can ensure the stable and synchronous movement of the two streamline mechanisms 41, and ensure smooth connection when the two streamline mechanisms 41 intersect and dock with the conveying mechanism 5.

[0041] Specifically: such as Figure 3 and Figure 4 As shown, both the streamlined mechanism 41 and the conveying mechanism 5 include a base 411, a second linear guide rail 412 arranged along the Y-axis direction on the base 411, a fixed plate 413 fixedly arranged on the base 411 and located at one end of the second linear guide rail 412, a movable plate 414 slidably arranged on the second linear guide rail 412, a first shaft 415 whose two ends are fixedly connected to the fixed plate 413 and the base 411 respectively, a locking member 416 fixedly connected to the movable plate 414 for locking with the first shaft 415, belt conveyor lines 417 respectively arranged on the movable plate 414 and the fixed plate 413, and a drive assembly 418. The first shaft 415 is provided with a scale line along the axial direction, and the drive assembly 418 is used to drive the two belt conveyor lines 417 to move synchronously.

[0042] In actual use, when jig 2 needs to be conveyed, the drive assembly 418 drives the two belt conveyor lines 417 to drive synchronously. The lower ends of both sides of jig 2 contact the two belt conveyor lines 417 respectively, and the jig 2 is conveyed through the synchronous transmission of the two belt conveyor lines 417. When the size of jig 2 changes and the spacing of the two belt conveyor lines 417 needs to be adjusted: loosen the locking piece 416, push the movable plate 414 along the axial direction of shaft 415, so that the movable plate 414 drives the belt conveyor line 417 set on the movable plate 414 to move synchronously as it moves along the linear guide rail 5. At this time, the position of the other belt conveyor line 417 remains unchanged, so that the spacing of the two belt conveyor lines 417 is adjusted to the appropriate position for jig 2. Then, the locking piece 416 is tightened again to fix the position of the movable plate 414.

[0043] In the above design, the structural design of the streamline mechanism 41 and the conveying mechanism 5 can realize the adjustment of the spacing of the belt conveyor line 417, so that the spacing of the two belt conveyor lines 417 can be adjusted to the position that the fixture 2 is adapted to.

[0044] Specifically: such as Figure 4 and Figure 5 As shown, the belt conveyor line 417 includes a drive pulley 171, a flat belt 172, and several driven pulleys 173. The flat belt 172 is connected to the drive pulley 171 and the several driven pulleys 173. The drive pulley 171 is coaxially provided with a prismatic hole. The drive assembly 418 includes a motor 181 mounted on a base 411, a drive pulley 182 mounted on the shaft of the motor 181, a prism 183 coaxially connected to the drive pulley 171 through the prismatic hole, a cylinder 186 coaxially fixedly connected to one end of the prism 183, a ball bearing, a driven pulley 185 coaxially fixedly mounted on the cylinder 186, and a synchronous belt 184 connected to the drive pulley 182 and the driven pulley 185. The ball bearing is mounted on the base 411 and the inner ring of the ball bearing is connected to the cylinder 186. The drive pulley 171 mounted on the movable plate 414 can move axially along the prism 183.

[0045] In actual use, the motor 181 drives the drive pulley 182 to rotate, and with the cooperation of the synchronous belt 184, the driven pulley 185 rotates. Since the driven pulley 185 is coaxially and fixedly connected to the cylinder 186, and the cylinder 186 is coaxially and fixedly connected to the end of the prism 183, the prism 183 rotates synchronously with the driven pulley 185. During the rotation of the prism 183, it drives the drive wheel 171 to rotate synchronously. With the cooperation of the driven wheel 173, the drive wheel 171 realizes the transmission of the flat belt 172, and the flat belt 172 transmission realizes the conveying function.

[0046] In the above design, the structural design and specific implementation of the belt conveyor line 417 and the drive component 418 enable the two conveyor lines to rotate synchronously under the drive of one drive component 418. At the same time, the design of the prism 183 and the drive wheel 171 ensures that the prism 183 can move relative to the drive wheel 171 without disassembly, which facilitates changing the spacing between the two belt conveyor lines 417.

[0047] Specifically: such as Figure 4 As shown, the streamlined mechanism 41 also includes a backstop 403, a stop assembly, and a lifting assembly mounted on the base 411. The stop assembly includes a first vertical plate mounted on the base 411, a third linear guide rail mounted on the first vertical plate, a stop block 402 slidably mounted on the third linear guide rail, and a first cylinder 401 mounted on the base 411 for driving the stop block 402 to rise and fall. The lifting assembly includes a stand 404 mounted on the base 411, a fourth linear guide rail vertically mounted on the stand 404, a top material rack 405 slidably mounted on the fourth linear guide rail, and a second cylinder 406 mounted on the base 411 for driving the top material rack 405 to rise and fall.

[0048] In actual use, fixture 2 moves towards the stop assembly along the direction of the anti-reverse device 403. The stop assembly then stops fixture 2, and the lifting assembly lifts fixture 2 for dispensing. During stopping, cylinder 401 drives the stop block 402 to rise and restrain fixture 2. During lifting, cylinder 406 drives the top material rack 405 to rise, lifting fixture 2 off the streamline mechanism 41.

[0049] In the above design, the structural design and specific implementation of the streamlined mechanism 41 can effectively realize the lifting and shortening of the height difference between the product and the dispensing mechanism 3 by the fixture 2, which facilitates the dispensing of the product in the fixture 2.

[0050] Specifically: such as Figure 7 and Figure 8As shown, the fixture 2 includes a base plate 21, a support base 22 mounted on the base plate 21 for supporting the mirror frame, a cover plate 23 hinged to the base plate 21, a latch 24 connecting the cover plate 23 and the base plate 21, and two elastic pressure members 25 located on both sides of the base plate 21 for lateral pressure on the mirror frame. Each elastic pressure member 25 includes a mounting block 251 mounted on the base 411, a first pin 257 mounted on the mounting block 251 along the Y-axis, a pressure plate 252 slidably mounted on the first pin 257, a spring 253 sleeved on the first pin 257, and a second pin mounted on the mounting block 251 along the Z-axis. The frame 1 is equipped with a shaft 254, a knob 258 rotatably mounted on the second pin 254, a third pin 259 mounted on the pressure plate 252, a metal plate 255 hinged to the third pin 259, and a magnet 256 mounted on the pressure plate 252 for magnetic connection with the metal plate 255. The frame 1 is also equipped with two sets of unlocking mechanisms 11, which are located on the feeding side of the conveyor line. The unlocking mechanism 11 includes a mounting frame 111, a third cylinder 112 mounted on the mounting frame 111, a rotary cylinder 113 mounted at the output end of the third cylinder 112, and a lever 114 eccentrically mounted at the output end of the rotary cylinder 113.

[0051] It should be noted that the side of the knob 258 is not a circumferential surface, resulting in a contact part A and a contact part B. The degree of pressure exerted by contact part A on the pressure plate 252 differs from that of contact part B, meaning the horizontal position of the pressure plate 252 on the first pin 257 is different. The pressure plate 252 has notches to accommodate the two protrusions 202. A portion of the ribbon cable extending out of the notch is pressed together by metal plates 255 and 252, while another portion of the ribbon cable remains within the notch 201.

[0052] In actual use, the latch 24 locks the cover plate 23 and the base plate 21, fixing the frame to the fixture 2. The hinges 200 at both ends of the frame are exposed. Before applying adhesive, the portion of the ribbon cable (not shown in the diagram) extending from the hinge 200 is pressed against the metal plate 255 and the pressure plate 252. The knob 258 is manually rotated beforehand, causing its abutting part A to press against the side of the pressure plate 252, compressing the spring 253. The pressure plate 252 moves along the first pin 257 towards the center of the frame, exposing the notch 201 of the hinge 200, thus avoiding the adhesive application. The adhesive application mechanism 3 then applies adhesive through the notch 201. When pressure needs to be maintained after the glue is applied, cylinder 112 drives rotary cylinder 113 to move down. Rotary cylinder 113 drives lever 114 to rotate, so that lever 114 drives knob 258 to rotate and contact the abutment part B of pressure plate 252 with pressure plate 252, so that the pressure plate 252 is reduced. Under the pressure of spring 253, pressure plate 252 moves outward along pin 257 to the outside of the frame, and squeezes the ribbon cable at notch 201 to ensure that the ribbon cable at notch 201 and the glue in notch 201 are cured.

[0053] In the above design, the structural design and specific implementation of fixture 2 can effectively achieve pressure holding of the frame, ensuring the normal progress of glue application and pressure holding.

[0054] Specifically: such as Figure 6 As shown, the dispensing mechanism 3 includes a gantry frame 31 mounted on the frame 1, a No. 5 linear guide rail mounted on the gantry frame 31 along the Y-axis, a sliding module 32 mounted on the No. 5 linear guide rail, a No. 5 linear module 32 fixedly mounted on the gantry frame 31 for driving the sliding module 33 to slide, a No. 6 linear guide rail mounted on the sliding module 33 along the X-axis, a transverse frame 35 mounted on the No. 6 linear guide rail, a No. 6 linear module 36 mounted on the sliding module 33 for driving the transverse frame 35, a No. 7 linear guide rail mounted vertically on the transverse frame 35, a lifting frame 37 mounted on the No. 7 linear guide rail, a No. 8 linear module 38 fixedly mounted on the transverse frame 35 for driving the lifting frame 37 to rise and fall, a dispensing machine 39 mounted on the lifting frame 37, and a vision inspection module 34.

[0055] In actual use, when glue dispensing is required, the sliding frame 33 is driven to move along the Y-axis by the No. 5 linear module 32, the transverse frame 35 is driven to move along the X-axis by the No. 6 linear module 36, and the lifting frame 37 is driven to rise and fall by the No. 8 linear module 38. Then, the product is photographed and positioned by the vision inspection module 34, and then the glue dispensing machine 39 performs glue dispensing.

[0056] In the above design, the structural design and specific implementation of the dispensing mechanism 3 can achieve the positioning of the dispensing position during dispensing.

[0057] Specifically: such as Figure 2 As shown, the frame 1 is also provided with a platform 6, on which a glue-wiping assembly 7, a needle-aligning assembly 8, and a glue bucket 9 are provided. The frame 1 is also provided with a return line 10 located below the conveyor line.

[0058] In actual use, the unloaded fixture 2 is transported through the return line 10.

[0059] In the above design, the wiping component 7 can be used to wipe the needle of the dispensing machine 39, and the needle alignment component 8 can be used to calibrate the needle of the dispensing machine 39.

[0060] The second embodiment provided in this application is a three-axis dispensing method, which uses the hinge 200 of the frame and the three-axis dispensing device of the wiring.
