Description

Technical Field

[0001] This invention relates to the field of barcode conveying equipment technology, and more specifically to a circuit board conveying barcode scanning mechanism. Background Technology

[0002] In the mass production of circuit boards, to achieve full-process tracking, quality traceability, and process inspection for each circuit board, the industry commonly uses the method of affixing unique identification barcodes to the circuit boards. This barcode, as the carrier of the circuit board's identity information, needs to ensure rapid and accurate identification at each stage of production. However, its placement is random, potentially located on the front or back of the circuit board. Furthermore, the dimensions (width, thickness) of circuit boards of different models and applications vary significantly, posing core requirements for the compatibility and full-coverage identification capabilities of barcode scanning equipment.

[0003] Currently, the circuit board scanning solutions on the market are mainly divided into two categories, both of which have obvious technical defects: The first is the manual scanning mode, in which operators need to manually find the barcode position on the circuit board and then use a barcode scanner to scan it. This method has high labor costs and low scanning efficiency, and cannot meet the requirements of large-scale production lines.

[0004] The second type is the production line integrated scanning solution, which mostly uses barcode scanners or readers in conjunction with movable tracks to achieve scanning. This type of solution has limiting shortcomings: (1) The scanning device needs to follow the track to align with the barcode. Some use a vision camera to position and then drive the track to move and scan the barcode. Others use an exhaustive method to let the barcode scanner traverse the board to find the barcode. The addition of movable tracks not only increases the cost of the equipment, but also the barcode scanner is prone to wear and breakage of the connecting wires due to long-term reciprocating motion, resulting in scanning failure. At the same time, collisions are also likely to occur during the movement, causing damage to the scanning device and reducing the service life of the equipment; (2) For the case where the barcode is located on the back of the circuit board, the existing solutions mostly use a flipping device to clamp the circuit board and flip it so that the barcode faces upward. In this process, it is very easy to touch the electronic components on the board, causing problems such as hidden damage to the circuit board and falling off of electronic components, which affects the product yield.

[0005] In summary, existing barcode scanning solutions suffer from low efficiency, high equipment wear and tear, easy damage to circuit boards, and poor compatibility, making it difficult to meet the demands for efficient, safe, and accurate barcode scanning in circuit board production. Therefore, there is an urgent need to develop a new type of circuit board conveying and scanning mechanism to address these technical pain points. Summary of the Invention

[0006] The purpose of this invention is to design a circuit board conveying and scanning mechanism that takes into account scanning efficiency, equipment stability, product safety, and multi-specification compatibility, and adapts to the actual needs of large-scale circuit board production.

[0007] To achieve the above objectives, the present invention specifically adopts the following technical solution: A circuit board conveying and scanning mechanism includes two sets of conveying tracks arranged in parallel. The two sets of conveying tracks are used to carry the circuit board below the edge so that it travels in a straight line. The area between the two sets of conveying tracks is a shooting area. An upper vision component and a lower vision component are arranged above and below the shooting area respectively. The upper vision component and the lower vision component are used to shoot the upper and lower surfaces of the circuit board to obtain a QR code.

[0008] Furthermore, the upper vision component includes an upper flat panel light source with a through hole in the middle and multiple upper connectors connecting the four corners of the upper flat panel light source. The upper connectors are installed on the inner wall of the housing, and an upper camera with a downward shooting direction is provided at the through hole, and the vertical height of the upper camera is adjustable.

[0009] Furthermore, the lower vision component includes a lower flat-panel light source with a through hole in the middle and lower connectors connecting the four corners of the lower flat-panel light source. The lower connectors are installed on the inner wall of the housing. A lower camera with the shooting direction facing upward is provided at the through hole. The lower camera is fixedly installed on the inner wall of the housing through a horizontal connector.

[0010] Furthermore, the conveying track includes a stop bar and first pulleys rotatably mounted at both ends of the stop bar. A transmission belt is driven between the two first pulleys. A belt support plate for supporting the lower surface of the transmission belt is mounted on the stop bar. Two second pulleys are also mounted on the stop bar. A servo motor mounted below the stop bar is arranged between the two second pulleys. A drive pulley is mounted on the output shaft of the servo motor. Pulling the transmission belt downwards causes it to wrap around the two second pulleys and the drive pulley in a triangular shape.

[0011] Furthermore, the conveying and scanning mechanism also includes an adjustment mechanism for adjusting the distance between the two stop bars. The adjustment mechanism includes two strip-shaped bases fixed parallel to each other on the inner wall of the housing. One strip-shaped base is fixedly connected to the bottom of one of the stop bars. A lead screw is rotatably installed between the two strip-shaped bases via a bearing, and a guide rod fixed to the strip-shaped base is also provided between the two. The bottom of the other stop bar is fixedly installed with a screw drum seat threaded to the lead screw and a guide shaft support slidably connected to the guide rod. A knob is fixed at the free end of the lead screw.

[0012] Furthermore, a lead screw module is vertically arranged on the back of the upper flat light source. The lead screw module is also fixedly installed on the inner wall of the housing through a transverse connector. The slider of the lead screw module is connected and installed with the upper camera.

[0013] Furthermore, an L-shaped connector is fixedly installed on one of the baffles, and a laser rangefinder facing the shooting area is fixed on the L-shaped connector.

[0014] Furthermore, the housing has through windows in the movable areas of the two baffles, and the through windows are used to connect to the external conveying equipment for conveying circuit boards.

[0015] Furthermore, a first operating door is hinged to the side of the housing where the knob is located on the lead screw, and a second operating door is hinged to the opposite side of the first operating door. A control panel is installed inside the housing and is located on one side of the second operating door. The control panel is electrically connected to the upper camera, lower camera, servo motor, servo motor of the lead screw module, laser rangefinder, and conveying equipment of the external conveying circuit board.

[0016] Furthermore, the field of view of the upper and lower cameras is 400mm x 400mm.

[0017] The beneficial effects of this invention are as follows: This invention employs a fixed-mount upper / lower camera with a 400x400mm field of view design, which can cover circuit boards within a range of 50mm-400mm. It eliminates the need for moving the camera via a movable track and avoids exhaustive searching for barcodes. Meanwhile, the surface light source ensures uniform brightness across the entire field of view and high barcode recognition accuracy. This reduces the cost of the moving track equipment and avoids the problems of circuit wear and collision damage caused by long-term reciprocating motion.

[0018] This invention uses an adjustment mechanism consisting of a lead screw, a guide rod, and a lead drum seat, along with a knob to manually adjust the spacing between two sets of conveyor tracks, making it compatible with circuit boards of different specifications within a width range of 50mm-400mm. The track spacing adjustment works in conjunction with the camera's wide field of view design to achieve dual compatibility of "width + coverage," significantly improving the equipment's versatility.

[0019] This invention uses a laser rangefinder to detect the thickness of the circuit board in real time. After the data is fed back to the control panel, the vertical height of the upper camera is finely adjusted by a lead screw module, thus achieving dynamic and precise focusing; this solves the problem of blurry focus when scanning circuit boards of different thicknesses.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0023] This invention provides a circuit board conveying and scanning mechanism that replaces the traditional flipping mechanism by using dual cameras for synchronous scanning. The dual vision components can simultaneously collect barcode information from both sides of the circuit board, fundamentally avoiding problems such as electronic components falling off and the circuit board being damaged during the flipping process. At the same time, the fixed camera with a 400x400mm wide field of view design eliminates the need for moving the barcode searcher, and the automated conveying and scanning work together, significantly improving efficiency compared to manual scanning. Furthermore, the track spacing is adjustable, and the upper camera's 33-degree dynamic focus adapts to circuit boards of different thicknesses. Combined with the wide field of view coverage, it is compatible with various models and specifications of circuit boards.

[0024] Please refer to this as well. Figures 1 to 3The mechanism includes two sets of parallel conveyor tracks 1. The two sets of conveyor tracks 1 are used to carry the circuit board below the edge and drive it to move in a straight line. The area between the two sets of conveyor tracks 1 is the shooting area 2. The upper vision component 3 and the lower vision component 4 are respectively arranged above and below the shooting area 2. The two work together to shoot the upper and lower surfaces of the circuit board to obtain the QR code.

[0025] Specifically, such as Figure 2 As shown, the upper vision component 3 includes an upper flat light source 31 with a through hole in the middle, and multiple upper connectors 32 connected to the four corners of the upper flat light source 31. The upper connectors 32 are metal hardware connectors, and their specific style is shown in the figure. The upper connectors 32 are fixedly installed on the inner wall of the housing 14 to achieve a stable assembly of the upper vision component 3. At the same time, an upper camera 33 with the shooting direction facing downward is provided at the through hole, and the vertical height of the upper camera 33 is adjustable to adapt to the focusing requirements of circuit boards of different thicknesses.

[0026] Specifically, such as Figure 3 As shown, the lower vision component 4 includes a lower flat light source 41 with a through hole in the middle, and lower connectors 42 connecting the four corners of the lower flat light source 41. The lower connectors 42 are also metal hardware connectors, as shown in the figure. The lower connectors 42 are installed on the inner wall of the housing 14. A lower camera 43 with the shooting direction facing upward is provided at the through hole. The lower camera 43 is fixedly installed on the inner wall of the housing 14 by the horizontal connectors 7 to keep the position fixed so as to cover the entire field of view.

[0027] During operation: Turn on the upper and lower flat panel light sources 41, adjust the brightness to suit the shooting requirements, ensure clear barcode imaging, and enable the barcodes on both sides of each circuit board conveyed by the conveyor track 1 to be accurately photographed and identified.

[0028] Please refer to this as well. Figures 4 to 6The conveying track 1 includes a stop bar 101 and first pulleys 102 rotatably mounted at both ends of the stop bar 101. A transmission belt 103 is sleeved between the two first pulleys 102, and the transmission belt 103 is in a taut state. A belt support plate 104 is installed on the stop bar 101. The belt support plate 104 is located in the loop of the transmission belt 103 and supports the lower surface of the upper transmission belt 103 to ensure that the belt is taut and does not collapse, ensuring that the circuit board enters the shooting area 2 smoothly along a straight line. Two second pulleys 105 are also installed on the stop bar 101. A servo motor 106 is installed between the two second pulleys 105 and installed below the stop bar 101. The output shaft of the servo motor 106 is equipped with a drive pulley 107. The drive pulley 107 pulls the transmission belt 103 downward, so that the transmission belt 103 is triangularly wrapped around the outside of the two second pulleys 105 and the drive pulley 107. During operation: The external conveying equipment delivers the circuit board to be scanned to the two sets of conveying tracks 1. The edge of the transmission belt 103 supports the lower edge of the circuit board. After the servo motor 106 starts, it drives the active pulley 107 to rotate, which drives the first pulley 102 to rotate through the transmission belt 103, thereby driving the transmission belt 103 to transport the circuit board. The support plate 104 simultaneously supports the upper transmission belt 103 to ensure that the belt does not collapse and the circuit board does not shift during the transport process. Example

[0029] Please refer to this as well. Figures 4 to 6 To improve equipment compatibility and adapt to circuit boards of different widths, the conveying and scanning mechanism also includes an adjustment mechanism 5 for adjusting the distance between the two stop bars 101. The adjustment mechanism 5 includes two strip-shaped bases 51 fixed parallel to each other on the inner wall of the housing 14. One of the strip-shaped bases 51 is fixedly connected to the bottom of one of the stop bars 101. A lead screw 52 is rotatably mounted between the two strip-shaped bases 51 via a bearing, and a guide rod 53 fixed to the strip-shaped base 51 is also provided between them. The bottom of the other stop bar 101 is fixedly mounted with a screw drum seat 54 threadedly connected to the lead screw 52, ​​and a guide shaft support 55 slidably connected to the guide rod 53. A knob 56 is fixed at the free end of the lead screw 52 for easy manual adjustment.

[0030] During operation: Based on the width of the circuit board to be scanned (adaptable range 50mm-400mm), rotate the knob 56 at the free end of the lead screw 52 to drive the lead screw 52 to rotate; the lead drum seat 54, which is threaded to the lead screw 52, ​​drives the corresponding stop bar 101 to move in a straight line under the limiting assistance of the guide rod 53 and the guide shaft support 55, adjusting the spacing of the two sets of conveying tracks 1 until it meets the edge support requirements of the circuit board, ensuring that the circuit board is transported smoothly without deviation.

[0031] With this setup, the track spacing can be manually adjusted via the adjustment mechanism 5, which consists of lead screw 52, ​​guide rod 53, and lead drum seat 54, and the knob 56. This allows for the adaptation of circuit boards of different specifications within a width range of 50mm-400mm, eliminating the need to customize dedicated barcode scanning devices for different circuit board models and greatly improving the equipment's versatility and adaptability.

[0032] Please refer to this as well. Figures 4 to 9 Considering the differences in circuit board thickness, precise focusing is required to ensure clear barcode imaging. A lead screw module 6 (a known and mature technology that can be directly selected by those skilled in the art) is vertically mounted on the back of the upper flatbed light source 31. The lead screw module 6 is fixedly installed on the inner wall of the housing 14 via a horizontal connector 7, and its slider 8 is fixedly connected to the upper camera 33, driving the upper camera 33 to move vertically. Simultaneously, an L-shaped connector 9 is fixedly installed on one of the baffles 101, and a laser rangefinder 10 facing the imaging area 2 is fixed on the L-shaped connector 9 for real-time detection of the height of the circuit board's upper surface. A through window 11 is provided in the movable area of ​​the two baffles 101, connecting to external conveying equipment to achieve seamless integration of fully automated circuit board conveying and barcode scanning.

[0033] Based on the layout design of the housing 14, a first operating door 12 is hinged to the side of the housing 14 where the knob 56 is located on the lead screw 52, ​​and a second operating door 13 is hinged to the opposite side of the first operating door 12, facilitating equipment debugging, cleaning, and troubleshooting. A control panel 15 is installed inside the housing 14, located to the side of the second operating door 13. The control panel 15 is a microcomputer that can input parameters according to actual production needs to regulate the operation of the entire equipment. The control panel 15 is electrically connected to the upper camera 33, lower camera 43, servo motor 106, the servo motor of the lead screw module 6, the laser rangefinder 10, and external conveying equipment. The lead screw module 6 drives the upper camera 33 to fine-tune its vertical height, achieving precise focusing and solving the problem of blurry focus when scanning circuit boards of different thicknesses. Simultaneously, with the microcomputer as the core, it links and controls various components to achieve full automation of the "conveyance-focusing-scanning-decoding-uploading" process, eliminating the need for manual intervention and completely replacing manual scanning, significantly reducing labor costs.

[0034] Please refer to this as well. Figures 1 to 9 The specific working process of the circuit board conveying and scanning mechanism provided by the present invention is as follows: 1. Confirm that the transmission belt 103 of the conveyor track 1 is undamaged, the support plate 104 is firmly supported, and the first and second pulleys 105 rotate smoothly; the flat light source of the upper and lower vision components 4 transmits light evenly, the camera lens is clean, and the field of view is unobstructed; the lead screw 52 and guide rod 53 of the adjustment mechanism 5 are not stuck, and the knob 56 rotates flexibly; the circuit connection of the laser rangefinder 10, lead screw module 6, servo motor 106, and control panel 15 is reliable and there is no poor contact.

[0035] 2. Turn on the power of the device and start the system through the control panel 15 (microcomputer). Link the upper and lower cameras 43, flat panel light source, servo motor 106, laser rangefinder 10 and external conveying equipment. Debug the signal transmission stability and ensure that the response of each component is synchronized. Calibrate the camera field of view (400x400mm) to ensure that the shooting range can cover the preset maximum specification circuit board.

[0036] 3. Based on the width of the circuit board to be scanned, rotate the knob 56 at the free end of the lead screw 52 to drive the lead screw 52 to rotate; the lead drum seat 54 drives the corresponding stop bar 101 to move in a straight line under the limiting assistance of the guide rod 53 and the guide shaft support 55, adjusting the spacing of the two sets of conveying tracks 1 until it meets the edge conveying requirements of the circuit board, ensuring that the circuit board is conveyed smoothly without deviation.

[0037] 4. Based on the thickness of the circuit board, the laser rangefinder 10 is preset to a detection threshold through the control panel 15; the laser rangefinder 10 (fixed to the L-shaped connector 9) emits a laser towards the shooting area 2 to detect the height of the upper surface of the circuit board in real time. After the data is transmitted to the control panel 15, it drives the lead screw module 6 and the slider 8 to move, fine-tuning the vertical height of the upper camera 33 to achieve precise focusing; the upper and lower flat light sources 41 are turned on and the brightness is adjusted to meet the shooting requirements to ensure clear barcode imaging.

[0038] 5. An external conveying device transports a test circuit board to the track through the through window 11, starts the conveying program, observes the conveying status of the circuit board, the camera focusing accuracy and the light source supplementary lighting effect, and completes the test run after confirming that there are no abnormalities.

[0039] 6. Start the continuous scanning mode. The external conveying device will transport the circuit board to be scanned to the two sets of conveying tracks 1 through the through window 11. The edge of the transmission belt 103 supports the lower edge of the circuit board. The servo motor 106 drives the transmission belt 103 to rotate, and the circuit board will smoothly enter the shooting area 2 along a straight line (the support plate 104 supports the upper transmission belt 103 at the same time to avoid collapse and displacement).

[0040] 7. After the circuit board enters the shooting area 2, the laser rangefinder 10 provides real-time feedback on the height data of the upper surface, and the control panel 15 dynamically fine-tunes the height of the upper camera 33 to maintain accurate focus; the upper and lower cameras 43 start synchronously, and under the supplementary light of a 400x400mm surface light source, they respectively shoot the front and back of the circuit board, quickly identify the barcode information and transmit it to the control panel 15; during the shooting process, there is no need to move the camera or flip the circuit board, so as to achieve full-area coverage scanning without blind spots.

[0041] 8. The circuit boards that have been scanned are transported by conveyor track 1, seamlessly connecting to subsequent external processes; subsequent circuit boards enter the shooting area 2 in sequence, repeating the above scanning process to achieve large-scale continuous operation.

[0042] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0043] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the present invention.
