Description

Technical Field

[0001] This invention relates to the field of laser engraving machine technology, specifically to a highly adaptable feeding mechanism based on a QR code automatic laser engraving machine. Background Technology

[0002] Laser engraving technology uses a laser engraving machine to ablate the surface layer of a PCB with low power, forming readable and valid information. The QR code contains technical information such as product barcode, model number, and version number.

[0003] In existing technologies, when circuit boards are transported to laser engraving machines via external conveying mechanisms, due to the limitations of the size of the external conveying mechanism itself and the planning location of the circuit board production line equipment in the factory, the external conveying mechanism often adopts a multi-segment structure, that is, changing the complete external conveying mechanism into a segmented conveying line to ensure that the external conveying mechanism can adapt to different types of circuit board transport.

[0004] When segmented conveyor lines are connected to laser engraving machines, the limitations of different laser engraving machine models prevent the external conveyor mechanism from connecting tightly to the internal conveyor track of the laser engraving machine. This causes the circuit board at the connection point of the crystalline silicon section to be partially suspended. As a result, when the circuit board is transferred, it will deviate from the predetermined trajectory due to the suspension at the end. This leads to expansion of the circuit board and the guide mechanism of the laser engraving machine, resulting in damage to the circuit board.

[0005] To address this issue, we propose a highly adaptable feeding mechanism based on an automatic QR code laser engraving machine. Summary of the Invention

Conveying rollers are symmetrically installed at both ends inside the side of the conveying track plates that are close to each other. The outer surfaces of the two conveying rollers located inside the same conveying track plate are driven by a synchronous belt. Connecting plates are fixedly installed on the bottom surfaces of the two synchronous belts. Clamping plates are fixedly installed at equal intervals on the surfaces of the two connecting plates that are close to each other. The centering component is driven by the auxiliary conveying component, and quickly aligns with the conveying track inside the laser engraving machine cabinet when adjusting the spacing between the two conveying track plates; The centering component includes a positioning shaft fixedly installed inside the conveyor mechanism cabinet, a positioning ring slidably installed on the surface of the positioning shaft, and a centering positioning plate fixedly installed on the upper surface of the positioning ring; The extended shock absorption components work in conjunction with the auxiliary conveying components to extend the synchronous belt conveying distance, shorten the distance between the synchronous belt and the conveying track, and reduce the shaking of the conveyed objects caused by multiple segments connecting. The extended shock absorption assembly includes a bonding track plate that is fixedly installed on one side of each of the two conveyor track plates. The bonding track plate has three limiting rings inside, and the outer surfaces of the three limiting rings are jointly fitted with a rubber belt.

[0008] Preferably, one of the conveyor track plates is threaded onto the outer surface of the drive screw, and the other conveyor track plate is fixedly installed on the upper surface of one side of the conveyor mechanism cabinet. The two conveyor track plates extend into the interior of the laser engraving machine cabinet from the surface of one side of the laser engraving machine cabinet.

[0009] Preferably, the auxiliary conveying assembly further includes a positioning frame plate fixedly installed in the middle of the upper surface of the pallet, and rollers are rotatably installed inside the upper surface of the positioning frame plate.

[0010] Preferably, the clamping plates on the two connecting plates are staggered, and two adjacent clamping plates are slidably installed on each other. The positioning frame plates on the two sets of clamping plates are staggered, and the top surface of the roller is flush with the top surface of the timing belt.

[0011] Preferably, the centering component also includes a connector fixedly installed on the bottom surface of the positioning ring, and folding plates symmetrically rotated and installed on both sides of the connector.

[0012] Preferably, the positioning ring, connector, and center positioning plate are located in the middle of the two conveyor track plates. The two sets of folding plates on both sides of the connector are rotatably installed at the bottom of the two conveyor track plates at the ends away from the connector. An indicator mark is provided on the middle part of the upper surface of the center positioning plate near the laser engraving machine cabinet to indicate the middle position of the two conveyor track plates.

[0013] Preferably, the extended shock absorption assembly also includes a limiting wheel rotatably mounted on one side surface of the track plate, a support spring fixedly installed inside the bottom end of the track plate, a driven block slidably mounted on one side of the top end of the track plate, a threaded rod horizontally threaded at the center of the driven block, and a handle fixedly mounted on the surface of one end of the threaded rod.

[0014] Preferably, the track plate is inverted L-shaped, and the three limiting rings are also inverted L-shaped. The limiting ring in the middle is rotatably installed on the surface of the corner of the track plate, and the other two limiting rings are slidably installed inside the track plate.

[0015] Preferably, the limiting wheel is rotatably installed at the corner of the track plate, and the outer surface of the limiting wheel is in contact with the outer surface of the limiting ring. The limiting wheel restricts the outer surface of the rubber belt, so that the rubber belt is in an inverted L shape that is in contact with the outer surface of the limiting ring. The support spring is vertically set, and the end of the support spring away from the track plate is fixedly installed on the upper surface of the limiting ring located in the vertical direction inside the track plate.

[0016] Preferably, one side surface of the driven block is rotatably connected to the center of a limiting ring located in the horizontal direction inside the mating track plate, and the threaded rod is rotatably installed in the middle of the two mating track plates on opposite sides.

[0017] Beneficial effects Compared with the prior art, the present invention provides a highly adaptable feeding mechanism based on a QR code automatic laser engraving machine, which has the following beneficial effects: By incorporating the track plate, limiting ring, and rubber belt, the rubber belt can serve as an extension of the external conveyor mechanism, thus fitting snugly against the conveyor track inside the laser engraving machine cabinet. This reduces the fluctuations in circuit board transport caused by gaps between the external conveyor mechanism and the internal conveyor track. As a flexible transition connector, the rubber belt tightly fits the inner and outer conveyor tracks, eliminating mechanical gaps and significantly reducing vibration and displacement caused by gaps, ensuring smooth circuit board transport. Furthermore, the deformable design of the rubber belt facilitates adaptation to laser engraving machines of different specifications, thereby improving the adaptability of the synchronous belt and rubber belt as external conveyors.

[0018] The deformable design of the rubber belt driven by the limiting ring facilitates quick changes in the horizontal length of the rubber belt, making it easy to connect with the conveyor rails inside the laser engraving machine cabinet of different lengths, thereby maintaining the continuous and stable conveying of the circuit board.

[0019] By using a centering positioning plate and a matching track plate, the external conveyor track and the internal conveyor track of the laser engraving machine cabinet can be quickly aligned, thereby improving the connection accuracy between the external and internal conveyor tracks.

[0020] By using equidistant and staggered positioning frame plates and rollers, the top surface of the rollers is always in contact with the center of the bottom of the circuit board when the circuit board is conveyed by the synchronous belt. The rollers are staggered to form a multi-point contact network, which ensures that the circuit board is subjected to uniform force and avoids the circuit board from being deflected during the conveying process, which could cause a single point to be suspended, and thus cause the circuit board to warp or shift. This keeps the center of gravity of the circuit board always within the support plane and effectively suppresses the lateral sway of the circuit board. Attached Figure Description

[0030] Among them, the two sets of interlocking clamps 25 and rollers 27 are always positioned between the two conveyor rails 15 to support the middle of the circuit board conveyed by the synchronous belt 23, so as to prevent the circuit board from becoming unbalanced during the transport of the circuit board on the surface of the synchronous belt 23.

[0031] The multiple rollers 27, which are equidistant and staggered, facilitate the application of uniform support force to the center of the circuit board.

[0032] Further embodiments Please see Figure 3 , Figure 4 and Figure 6 The highly adaptable feeding mechanism based on the QR code automatic laser engraving machine also includes a centering component. The centering component is driven by the auxiliary conveying component and quickly aligns with the conveying track inside the laser engraving machine cabinet 11 when adjusting the distance between the two conveying track plates 15.

[0033] The centering component includes a positioning shaft 31 fixedly installed inside the conveying mechanism cabinet 12, a positioning ring 32 slidably installed on the surface of the positioning shaft 31, and a centering positioning plate 35 fixedly installed on the upper surface of the positioning ring 32.

[0034] The centering component also includes a connector 33 fixedly mounted on the bottom surface of the positioning ring 32, and folding plates 34 symmetrically rotated and mounted on both sides of the connector 33.

[0035] The positioning ring 32, the connector 33, and the centering positioning plate 35 are located in the middle of the two conveying track plates 15. The two sets of folding plates 34 located on both sides of the connector 33 are rotatably installed at the bottom of the two conveying track plates 15 at the ends away from the connector 33. An indicator mark is provided on the middle part of the upper surface of the centering positioning plate 35 near the laser engraving machine cabinet 11 to indicate the middle position of the two conveying track plates 15.

[0036] The folding plate 34 is composed of multiple connecting rods that are hinged to each other.

[0037] Further embodiments Please see Figures 4 to 9 The highly adaptable feeding mechanism based on the QR code automatic laser engraving machine also includes an extended shock absorption component. The extended shock absorption component works in conjunction with the auxiliary conveying component to extend the conveying distance of the synchronous belt 23, shorten the gap between the synchronous belt 23 and the conveying track, and reduce the shaking of the object conveying caused by multi-segment connection.

[0038] The extended shock absorption assembly includes a bonding track plate 41 that is fixedly installed on one side of each of the two conveyor track plates 15. The bonding track plate 41 has three limiting rings 42 inside, and the outer surfaces of the three limiting rings 42 are jointly driven by a rubber belt 43.

[0039] The extended shock absorption assembly also includes a limiting wheel 44 rotatably mounted on one side surface of the track plate 41, a support spring 45 fixedly mounted inside the bottom end of the track plate 41, a driven block 46 slidably mounted on one side of the top end of the track plate 41, a threaded rod 47 horizontally threaded at the center of the driven block 46, and a handle 48 fixedly mounted on the surface of one end of the threaded rod 47.

[0040] The track plate 41 is inverted L-shaped, and the three limiting rings 42 are also inverted L-shaped. The limiting ring 42 in the middle is rotatably installed on the surface of the corner of the track plate 41, and the other two limiting rings 42 are slidably installed inside the track plate 41.

[0041] The limiting wheel 44 is rotatably installed at the corner of the track plate 41, and the outer surface of the limiting wheel 44 is attached to the outer surface of the limiting ring 42. The limiting wheel 44 restricts the outer surface of the rubber belt 43, so that the rubber belt 43 is in an inverted L shape attached to the outer surface of the limiting ring 42. The support spring 45 is vertically set, and the end of the support spring 45 away from the track plate 41 is fixedly installed on the upper surface of the limiting ring 42 located in the vertical direction inside the track plate 41.

[0042] Among them, one side surface of the driven block 46 is rotatably connected to the center of the limiting ring 42 located in the horizontal direction inside the mating track plate 41, and the threaded rod 47 is rotatably installed in the middle of the two mating track plates 41 on opposite sides.

[0043] The centering positioning plate 35 and the fitting track plate 41 are designed to facilitate the rapid alignment of the synchronous belt 23 with the conveyor track inside the laser engraving machine cabinet 11. The rubber belt 43, as an extension of the synchronous belt 23, can be connected with the conveyor track inside the laser engraving machine cabinet 11 of different specifications, increasing the adaptability of the device.

[0044] The support spring 45 is used to limit the position of the limiting ring 42 that is fixedly connected to it, thereby keeping the rubber belt 43 in a taut state and preventing the rubber belt 43 from loosening.

[0045] The overall working process and principle of the above embodiments are as follows: Position adjustment of the conveyor mechanism: The operator starts the drive motor 13 through the control device, and drives the drive screw 14 fixedly connected to it to rotate through the output shaft end of the drive motor 13. This causes the conveyor track plate 15 threaded to the surface of the drive screw 14 to move closer to the conveyor track plate 15 located on the conveyor mechanism cabinet 12, until the distance between the two conveyor track plates 15 is equal to the width of the conveyor track inside the laser engraving machine cabinet 11.

[0046] It should be noted that the start-up of the drive motor 13 is achieved by a controller installed on the conveyor cabinet 12, and the above process is existing technology, so it will not be described in detail here.

[0047] During the above process, as the two conveyor track plates 15 approach each other, the folding plate 34, which is rotatably connected between the bottom ends of the two conveyor track plates 15, will deform. Since the folding plate 34 is composed of multiple connecting rods that are hinged to each other, the folding plate 34 will shrink as the distance between the two conveyor track plates 15 shortens. Therefore, the connecting piece 33 set between the two sets of folding plates 34 will move accordingly, and through the connecting piece 33, the positioning ring 32 will be driven to move horizontally on the surface of the positioning shaft 31.

[0048] The positioning shaft 31 has a groove on its surface for the positioning ring 32 to move horizontally, which ensures that the positioning ring 32 can move horizontally stably on the surface of the positioning shaft 31.

[0049] Meanwhile, a centering positioning plate 35 is fixedly connected to the top surface of the positioning ring 32, and an indicator mark is provided on the side of the centering positioning plate 35 closest to the laser engraving machine cabinet 11 to indicate the center of the conveyor track inside the laser engraving machine cabinet 11, so as to quickly align the synchronous belt 23 on the two conveyor track plates 15 with the surface of the conveyor track.

[0050] Extension of the external conveying mechanism: In the prior art, when laser engraving a circuit board, an external conveying mechanism is used to transport the circuit board into the laser engraving machine cabinet 11 to complete the laser engraving of the circuit board's QR code. In order to meet the continuous transport of the circuit board, the external conveying mechanism is often divided into multiple transport paths. Due to the size limitations of the existing conveying mechanism cabinet 12 and the length limitations of the transport track inside the laser engraving machine cabinet 11, there is still a certain distance between the external conveying mechanism and the edge of the transport track. This results in a break at the connection of the track segment, causing fluctuations in the stable transport of the circuit board and a shift in the position of the circuit board.

[0051] Therefore, after the positions of the two conveyor track plates 15 are adjusted, the mating track plate 41 located on the side of the two conveyor track plates 15 closest to the laser engraving machine cabinet 11 will be inside the laser engraving machine cabinet 11. It should be noted that at this time, the inner surface of the mating track plate 41, which is the extension end of the conveyor track plate 15, will be in contact with the edge of the conveyor track inside the laser engraving machine cabinet 11. In addition, due to the presence of the mating track plate 41, when adjusting the distance between the two conveyor track plates 15, it is also possible to determine whether the external conveying mechanism is aligned with the conveyor track by observing whether the mating track plate 41 is in contact with the edge of the conveyor track inside the laser engraving machine cabinet 11.

[0052] After the installation of the track plate 41 is completed, the staff will manually hold the handle 48 and control the handle 48 to rotate on the track plate 41. The handle 48 drives the threaded rod 47 to rotate. The rotation of the threaded rod 47 installed on the track plate 41 causes the driven block 46 threaded to it to move horizontally inside the track plate 41. At this time, a limiting ring 42 rotatably connected to the driven block 46 will also move synchronously inside the track plate 41.

[0053] Since the three limiting rings 42 are arranged in an inverted L shape, the limiting ring 42 in the middle is rotatably installed on the surface of the corner of the track plate 41, and the other two limiting rings 42 are slidably installed inside the track plate 41. The surfaces of the three limiting rings 42 are connected to the rubber belt 43 for transmission. Therefore, when the limiting ring 42 rotatably connected to the driven block 46 moves, the deformation of the rubber belt 43 will cause another limiting ring 42 slidably connected inside the track plate 41 to make a vertical displacement in the vertical direction. When the limiting ring 42 moves, it will compress the support spring 45 fixedly installed on its top, thereby moving the rubber belt 43 in the horizontal direction closer to the edge of the conveyor track inside the laser engraving machine cabinet 11 until the rubber belt 43 contacts the edge of the conveyor track, thus completing the extension of the external conveyor mechanism.

[0054] It should be noted that during the above process, while the support spring 45 is contracting and deforming, it will generate a spring force in the opposite direction to the deformation force due to its own elasticity. As a result, the limiting ring 42 after horizontal displacement and the limiting ring 42 after vertical displacement can always keep the rubber belt 43 in a taut state, thereby avoiding the situation where the rubber belt 43, which serves as an extension track, becomes loose after deformation, thus affecting the circuit board transportation.

[0055] Circuit board delivery: After the external conveying mechanism is installed, the stepper motor 21 is started by the controller. The output shaft of the stepper motor 21 drives the conveyor roller 22, which is fixedly connected to it, to rotate. Through the transmission connection between the conveyor roller 22 and the synchronous belt 23, the synchronous belt 23 is made to rotate continuously, thereby conveying the circuit board to the laser engraving machine cabinet 11.

[0056] It should be noted that as the two conveyor track plates 15 approach each other, the connecting plates 24 fixedly connected to the two conveyor track plates 15 will also approach each other. At this time, the clamping plates 25 fixedly connected to the connecting plates 24 will also approach each other. Since the clamping plates 25 located at equal intervals on the two connecting plates 24 are slidably installed on each other, and the two sets of clamping plates 25 are staggered, the two sets of clamping plates 25 will be inserted and installed on each other. At the same time, the positioning frame plate 26 and the roller 27 on the clamping plates 25 will also move synchronously.

[0057] Since the upper surface of the roller 27 is flush with the upper surface of the timing belt 23, when the two timing belts 23 transport the circuit board, the multiple rollers 27 set between the two timing belts 23 will act as support members in the middle of the circuit board, thereby assisting in the transportation of the circuit board and ensuring the stable transportation of the circuit board on the timing belt 23.

[0058] Subsequently, the circuit board is transferred through the surface of the rubber belt 43 and enters the laser engraving machine cabinet 11, thus completing the circuit board conveying operation.

[0059] It should be noted that during the above process, when the circuit board is on the rubber belt 43, the rubber belt 43 itself will not rotate, and one end of the circuit board is always on the surface of the synchronous belt 23 in motion. After the other end of the circuit board leaves the rubber belt 43 and comes into contact with the conveyor track inside the laser engraving machine cabinet 11, the circuit board will be conveyed again by the conveyor track inside the laser engraving machine cabinet 11 in motion. Therefore, the rubber belt 43, as the extension end of the synchronous belt 23, will not affect the continuous conveying of the circuit board.

[0060] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
