Description

Technical Field

[0001] This utility model relates to the field of circuit board surface assembly production line technology, and in particular to a circuit board assembly docking station capable of scanning labels. Background Technology

[0002] Printed circuit boards, also known as PCBs, are used in surface mount assembly lines to mount or assemble components onto the surface of circuit boards. In PCB assembly lines, transfer tables are typically used to transport circuit boards between adjacent processing equipment.

[0003] Common transfer stations include automated conveyor systems that transport circuit boards from one workstation to the next. Some transfer stations also include label scanning devices to scan labels on the circuit boards. However, these devices are fixed in position and can only scan one side of the PCB. If the label is on the other side of the PCB, scanning will fail. Therefore, existing transfer stations with label scanning devices generally suffer from poor applicability.

[0004] In summary, how to provide a more suitable docking station is a problem that urgently needs to be solved in the field of PCB surface mount assembly production line technology. Utility Model Content

[0005] This invention provides a circuit board assembly docking station capable of scanning tags, thereby solving the technical problem of poor applicability of existing docking stations.

[0006] To solve the aforementioned technical problems, the present invention adopts the following technical solution:

[0007] A circuit board assembly docking station capable of scanning labels includes a frame and an operating module mounted on the frame. The frame includes a housing and two mounting seats.

When the label scanning device is mounted on the mounting seat in the upper cavity, the label scanning device is located above the conveying mechanism. When the label scanning device is mounted on the mounting seat in the lower cavity, the label scanning device is located below the conveying mechanism and directly facing the bottom window.

[0008] In one embodiment, the label scanning device is linearly reciprocating and slidingly against the mounting base; the trajectory of the label scanning device is parallel to the transmission surface of the conveying mechanism and perpendicular to the conveying direction of the conveying mechanism.

[0011] In one embodiment, the slider is provided with a locking mechanism. When the locking mechanism is in the locked state, the locking mechanism restricts the slider from sliding along the slide groove; when the locking mechanism is in the unlocked state, the slider can slide along the slide groove.

[0012] In one embodiment, the locking mechanism includes a threaded rod and a limiting member. The upper end of the threaded rod is provided with a nut, and the lower end of the threaded rod is threadedly connected to a threaded hole opened on the slider. The limiting member is connected to the lower end of the threaded rod and is partially located in the slide groove. When the threaded rod moves up and down relative to the slider, the threaded rod drives the limiting member to move up and down in the slide groove.

[0013] In one embodiment, the conveying mechanism includes two support plates symmetrically disposed on the machine frame, two conveyor belts respectively disposed on the two support plates, and a drive assembly for simultaneously driving the two conveyor belts; the two conveyor belts are configured to support both sides of the circuit board respectively; when the label scanning device is mounted on the mounting base, the orthographic projection of the label scanning device on the conveying surface of the conveying mechanism is located between the two conveyor belts.

[0014] In one embodiment, the conveyor belt includes a pulley assembly disposed on a support plate and a connecting belt sleeved on the pulley assembly; the connecting belt forms a support portion extending along the conveying direction of the conveying mechanism under the limiting position of the pulley assembly, and the support portion supports the circuit board; the drive assembly drives the pulley assemblies of the two conveyor belts simultaneously through a connecting shaft, so that the pulley assembly drives the connecting belt to convey the circuit board.

[0015] In one embodiment, an abutment platform is provided on the inner sidewall of the support plate, and the abutment platform extends along the conveying direction of the conveying mechanism; the abutment platform is located below the support portion and abuts against the bottom surface of the support portion; the pulley set includes a driving pulley, two driven pulleys and multiple tension pulleys; the two driven pulleys are respectively located at both ends of the abutment platform, and each tension pulley is located below the driven pulley; the two ends of the connecting shaft are rotatably connected to the two support plates; the driving pulleys of the two pulley sets are sleeved on the connecting shaft; the drive assembly includes a drive motor and a shaft coupling, the drive motor is fixed to the outer sidewall of a support plate, and the shaft of the drive motor is coaxially connected to the connecting shaft through the shaft coupling, and the drive motor drives the connecting shaft to rotate.

[0016] In one embodiment, the upper cavity has an inlet window and an outlet window on its two opposite vertical sidewalls; the inlet end of the conveying mechanism extends from the inlet window to the outside of the housing, and the outlet end of the conveying mechanism extends from the outlet window to the outside of the housing; the two mounting seats are located above and below the inlet window, respectively.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention relates to a detachable label scanning device, with a mounting base in both the upper and lower cavities. The label scanning device is selectively installed in one of the two mounting bases based on the location of the circuit board label, adapting to the scanning requirements of different circuit boards. Normally, the label scanning device is mounted in the upper cavity mounting base, with a baffle plate sealing the bottom window of the upper cavity to maintain a relatively closed state, providing a degree of dust prevention and catching any fallen objects. In special cases, the label scanning device is mounted in the lower cavity mounting base; in this case, the baffle plate is removed, and the label scanning device scans the circuit board label from the bottom window upwards. Using the aforementioned solution, this invention can scan both circuit boards with front and back labels, offering better applicability compared to existing docking stations.

[0044] Please see Figures 1 to 4This embodiment provides a circuit board assembly docking station capable of scanning tags, including a machine frame 10 and an operation module disposed on the machine frame 10. The operation module is capable of completing the conveying process of circuit boards 70 to adjacent equipment in the production line, including but not limited to. The operation module is powered by an external power supply to achieve operation.

[0045] The machine frame 10 includes a housing and two mounting bases 100. The housing has an upper cavity 101 and a lower cavity 102 arranged in a vertical direction. The bottom wall of the upper cavity 101 has a bottom window 1012 that passes through the lower cavity 102. The bottom window 1012 has a removable cover plate 1011, which closes the bottom window 1012. Specifically, the cover plate 1011 can be fixed to the upper surface of the bottom window 1012 with screws. When it is necessary to remove the cover plate 1011, the screws can be unscrewed to remove the cover plate 1011. The two mounting bases 100 are respectively fixed to the inner wall of the upper cavity 101 and the inner wall of the lower cavity 102 by fasteners. Preferably, the two mounting bases 100 are located on the same side of the housing.

[0046] The operating module includes a conveyor mechanism 20 for conveying the circuit board 70 and a label scanning device 90 for scanning the labels on the circuit board 70. Of course, the operating module also includes other commonly used components, such as the control unit 50, the electronic control system, the heat dissipation system, and other components commonly used in the prior art, which will not be described in detail here.

[0047] The conveying mechanism 20 is located inside the upper cavity 101 and is used to convey the circuit board 70. The circuit board 70 enters from the inlet end 201 of the conveying mechanism 20 and exits from the outlet end 202. Therefore, it can be assumed that the conveying direction of the conveying mechanism 20 is from the inlet end 201 to the outlet end 202, and the conveying direction mentioned below should also be understood in this way.

[0048] The label scanning device 90 is detachably mounted on one of the two mounting bases 100. When the label scanning device 90 is mounted on the mounting base 100 in the upper cavity 101, it is positioned above the conveying mechanism 20 and scans the labels on the upper surface of the circuit board 70 conveyed by the conveying mechanism 20 from top to bottom. When the label scanning device 90 is mounted on the mounting base 100 in the lower cavity 102, it is positioned below the conveying mechanism 20 and directly facing the bottom window 1012. The label scanning device scans the labels on the lower surface of the circuit board 70 of the conveying mechanism 20 from bottom to top through the bottom window 1012. The operation of both the conveying mechanism 20 and the label scanning device 90 is controlled by a control unit 50 built into the machine frame 10. The control unit 50 can be a PLC controller, an MCU processor, or other microprocessor capable of data analysis, processing, and control functions.

[0049] Compared with the prior art, the label scanning device 90 in this embodiment is designed as a detachable device. A mounting base 100 is provided in both the upper cavity 101 and the lower cavity 102. The label scanning device 90 is selectively installed in one of the two mounting bases 100 according to the position of the label on the circuit board 70, to adapt to the scanning needs of different circuit boards 70. Normally, the label scanning device 90 is installed in the mounting base 100 of the upper cavity 101, and a baffle plate 1011 closes the bottom window 1012 of the bottom wall of the upper cavity 101, keeping the upper cavity 101 relatively closed, providing a certain degree of dust prevention and collection of fallen objects. In special cases, the label scanning device 90 is installed in the mounting base 100 of the lower cavity 102. In this case, the baffle plate 1011 is removed, and the label scanning device 90 scans the label on the circuit board 70 from the bottom window 1012 upwards. Using the aforementioned solution, this embodiment can scan both circuit boards 70 with front labels and circuit boards 70 with back labels, making it more versatile than existing docking stations.

[0050] Next, the various structural connection schemes of this utility model will be further illustrated by way of examples.

[0051] Please continue reading. Figures 1-4 In some embodiments, the housing has an inlet window and an outlet window, which respectively penetrate the upper cavity 101 and are located on opposite sides of the upper cavity 101. A conveying mechanism 20 is disposed within the upper cavity 101 of the housing. The inlet end 201 of the conveying mechanism 20 extends out of the housing from the inlet window, and the outlet end 202 of the conveying mechanism 20 extends out of the housing from the outlet window. The housing serves a dustproof and protective function, preventing external dust and impurities from contaminating the circuit board 70 and preventing foreign objects from impacting the circuit board 70.

[0052] Please combine Figure 2 , Figure 5 and Figure 6 In one embodiment, the label scanning device 90 is linearly reciprocating and slidingly against the mounting base 100. The trajectory of the label scanning device 90 is parallel to the transmission surface of the conveying mechanism 20, which can be understood as the plane where the circuit board 70 is located or the plane where the bottom sidewall of the circuit board 70 is located. Furthermore, the trajectory of the label scanning device 90 is also perpendicular to the conveying direction of the conveying mechanism 20. The label scanning device 90 slides relative to the mounting base 100 to adjust its scanning position, making it suitable for scanning different batches and models of circuit boards 70, thus having a wide range of applications.

[0053] In one embodiment, the mounting base 100 is provided with a slide groove 110. The label scanning device 90 includes a scanning body 901, a connecting frame 902, and a slider 903. The slider 903 slidably engages with the slide groove 110. Specifically, the slider 903 includes a protruding portion that inserts into the slide groove 110, thus allowing the slider 903 to slide against the slide groove 110 via the protruding portion. In a preferred embodiment, a spindle guide rail can be used to replace the mounting base 100 and the slider 903. The spindle guide rail is a readily available standard part and belongs to the prior art; therefore, its structure will not be described in detail here.

[0054] The scanning body 901 scans the labels on the circuit board 70 to obtain the marking information contained in the labels, and then transmits the marking information to the control unit 50. The control unit 50 stores the marking information in a storage module, such as in a database or a separately configured storage medium, for easy retrieval later. The scanning body 901 can use commonly used scanning components in the industry; its specific structure and working principle will not be described in detail here. In some embodiments, the scanning body 901 can scan the labels on the circuit board 70 while it is moving (at a slow or high speed), without waiting for the circuit board 70 to stop moving before scanning the labels. Furthermore, the scanning body 901 can scan multiple labels at once, thereby improving its scanning efficiency. In addition, the scanning body 901 can also achieve wide-angle reading, large-field-of-view reading, and long-distance reading to broaden its applicability.

[0055] In some embodiments, the connecting frame 902 is configured with an adjustable angle, thereby allowing the scanning angle of the scanning body 901 to be adjusted. The upper cavity 101 and lower cavity 102 provide ample operating space for adjusting the scanning angle of the scanning body 901. Specifically, the connecting frame 902 includes a first rod 9021, a second rod 9022, and a hinge seat 9023. One end of the first rod 9021 is fixed to the slider 903, and the other end of the first rod 9021 is rotatably connected to the second rod 9022 via the hinge seat 9023. The scanning body 901 is fixed to the second rod 9022. By manually pushing the scanning body 901, the scanning body 901 can cause the second rod 9022 to swing relative to the hinge seat 9023, thereby adjusting the position of the scanning body 901 to obtain the optimal scanning angle. In addition, the scanning body 901 can be used to scan labels of different models and batches of circuit boards 70, making it widely applicable.

[0056] Furthermore, the hinge base 9023 includes two bases and a pin. The two bases are sleeved on the pin and are respectively fixed to the first rod 9021 and the second rod 9022. In the absence of external force, the friction between the bases and the pin fixes their relative positions, thereby fixing the relative positions of the first rod 9021 and the second rod 9022. Consequently, the position of the scanning body 901 is also fixed, allowing the scanning body 901 to continuously maintain a fixed scanning angle to scan the labels of various circuit boards 70 of the same batch and model. Of course, in other embodiments, the hinge base 9023 can also adopt commercially available structural components capable of achieving hinge functionality, which will not be elaborated upon here.

[0057] In some embodiments, in order for the slider 903 to slide along the mounting base 100 during the tag scanning process, a locking mechanism is provided on the slider 903 to limit the slider 903 to the mounting base 100. When the locking mechanism is in the locked state, the locking mechanism restricts the slider 903 from sliding along the slide groove 110; when the locking mechanism is in the unlocked state, the slider 903 can slide along the slide groove 110.

[0058] In one embodiment, the locking mechanism includes a threaded rod 9031 and a limiting member 9032. The upper end of the threaded rod 9031 is provided with a nut, and the lower end is threadedly connected to a threaded hole in the slider 903. The limiting member 9032 is connected to the lower end of the threaded rod 9031 and is partially located in the groove 110 of the mounting base 100. When the threaded nut is manually tightened, the threaded rod 9031 moves up and down relative to the slider 903, thereby driving the limiting member 9032 to move up and down. When the limiting member 9032 moves upward and abuts against the upper sidewall inside the groove 110 of the mounting base 100, the locking mechanism is in a locked state. The friction between the limiting member 9032 and the upper sidewall inside the groove 110 restricts the movement of the limiting member 9032 along the groove 110, and the limiting member 9032 also restricts the threaded rod 9031 and the slider 903 from sliding along the groove 110. When the limiting member 9032 moves down and away from the upper side wall inside the slide groove 110, the locking mechanism is in the unlocked state. At this time, the limiting member 9032 can move freely relative to the slide groove 110. By manually pushing the slider 903, the slider 903 can slide along the slide groove 110 of the mounting base 100, thereby freely adjusting the position of the label scanning device 90.

[0059] Please combine Figures 7-13In one embodiment, the conveying mechanism 20 includes two support plates 211 symmetrically disposed on the machine frame 10, two conveyor belts 21 respectively disposed on the two support plates 211, and a drive assembly 22 for simultaneously driving the two conveyor belts 21. The two conveyor belts 21 are configured to support both sides of the circuit board 70 respectively. Driven by the drive assembly 22, the two conveyor belts 21 act synchronously on both sides of the circuit board 70, thereby pushing the circuit board 70 forward. With the aforementioned structural solution, a clearance space can be formed between the two conveyor belts 21 to avoid components on the bottom surface of the circuit board 70. The orthographic projection of the label scanning device on the conveying surface of the conveying mechanism is located between the two conveyor belts. Specifically, the label scanning device is directly above the position between the two conveyor belts, so that the label scanning device can scan the labels on the surface of the circuit board from top to bottom.

[0060] In one embodiment, the conveyor belt 21 includes a pulley assembly disposed on a support plate 211 and a connecting belt 2122 sleeved on the pulley assembly. The connecting belt 2122, under the constraint of the pulley assembly, forms a support portion 2123 extending along the conveying direction of the conveying mechanism 20, which supports the circuit board 70. The drive assembly 22 simultaneously drives the pulley assemblies of both conveyor belts 21 via a connecting shaft 23, so that the pulley assemblies drive the connecting belt 2122 to convey the circuit board 70.

[0061] In one embodiment, the pulley assembly includes a driving pulley 2124, two driven pulleys 2121, and multiple tension pulleys 2125. The two driven pulleys 2121 are located at both ends of the abutment platform 2112, and the two driven pulleys 2121 limit the movement of the connecting belt 2122 to form a support portion 2123. Each tension pulley 2125 is located below the driven pulleys 2121 and is used to provide tension to the connecting belt 2122. The two ends of the connecting shaft 23 are rotatably connected to two support plates 211, and the driving pulleys 2124 of the two pulley assemblies are sleeved on the connecting shaft 23. When the connecting shaft 23 rotates, it drives the driving pulleys 2124 of the two pulley assemblies to rotate synchronously.

[0062] The following are the implementation methods for installing the two support plates 211:

[0063] In one embodiment (not shown), both support plates 211 can be fixedly attached to the machine frame 10. The distance between the two support plates 211 is not adjustable. The method by which the support plates 211 are fixedly attached to the machine frame 10 is not limited here.

[0064] Please continue reading. Figures 5 to 7In one embodiment, one of the two support plates 211 is movably connected to the machine frame 10, and the other is fixedly connected to the machine frame 10. Specifically, the machine frame 10 has a first built-in plate 11 and a second built-in plate 12 inside. The first built-in plate 11 and the second built-in plate 12 are fixed to the inner wall of the machine frame 10 by fasteners. The bottoms of the first built-in plate 11 and the second built-in plate 12 are connected by a base plate 13, wherein the base plate 13 forms part of the bottom wall of the upper cavity 101, and the bottom window 1012 is opened on the base plate 13. A guide rod 81 is provided between the first built-in plate 11 and the second built-in plate 12. The number of guide rods 81 can be one, two, or more. The guide rod 81 is perpendicular to the first built-in plate 11 and the second built-in plate 12, and its two ends are respectively connected to the first built-in plate 11 and the second built-in plate 12. The two support plates 211 are disposed between the first built-in plate 11 and the second built-in plate 12 and are sleeved on the guide rods 81. The support plate 211 near the first built-in plate 11 is fixed to the first built-in plate 11 by fasteners and cannot slide relative to the guide rod 81. The support plate 211 near the second built-in plate 12, however, can slide back and forth along the axial direction of the guide rod 81 relative to the guide rod 81.

[0065] Furthermore, the distance between the two support plates 211 can be adjusted by a lead screw mechanism. Specifically, the lead screw mechanism includes a lead screw shaft 80, a lead screw sleeve, and a lead screw motor. The two ends of the lead screw shaft 80 pass through the first inner plate 11 and the second inner plate 12, respectively, and are rotatably connected to both the first inner plate 11 and the second inner plate 12. The lead screw motor is fixed to the side of the first inner plate 11 facing away from the support plate 211, and its shaft is connected to the lead screw shaft via a coupling member. The lead screw sleeve is fitted onto the lead screw shaft 80 and threadedly connected to it. The support plate 211 closest to the first inner plate 11 is fixedly connected to the lead screw sleeve; specifically, the lead screw sleeve is inserted into the corresponding support plate 211 and fixedly connected to it by fasteners. When the lead screw motor drives the lead screw shaft 80 to rotate in both directions, the lead screw shaft 80 forces the lead screw sleeve to reciprocate along the axial direction of the lead screw shaft 80. This causes the lead screw sleeve to move the corresponding support plate 211 away from and closer to the other support plate 211, adjusting the distance between the two support plates 211, and ultimately adjusting the distance between the two conveyor belts 21. In some applications, the distance between the supports of the two conveyor belts 21 can be adjusted using the aforementioned method, allowing the conveying mechanism 20 to be adapted to convey circuit boards 70 of different widths.

[0066] In one embodiment, both support plates 211 are movably connected to the machine frame 10. The connection scheme of the support plates 211 in this embodiment differs from the previous embodiment in that the lead screw mechanism includes two lead screw sleeves, with the internal threads of the two lead screw sleeves rotating in opposite directions. The two support plates 211 are respectively fixed to the two lead screw sleeves. When the lead screw motor drives the lead screw shaft 80 to rotate, the lead screw shaft 80 drives the two lead screw shaft sleeves 80 to move closer and further apart, thereby causing the two lead screw sleeves to drive the two support plates 211 to move closer and further apart.

[0067] Next, the structure of the support plate 211 will be further illustrated by example.

[0068] Please combine Figure 9 and Figure 10 In one embodiment, an abutment platform 2112 protrudes from the inner sidewall of the support plate 211. Preferably, the abutment platform 2112 is integrally formed with the support plate 211. The abutment platform 2112 extends along the conveying direction of the conveying mechanism 20. The abutment platform 2112 is located below the support portion 2123 and abuts against the bottom surface of the support portion 2123 to provide support for the support portion 2123 and prevent the support portion 2123 from being deformed by the pressure of the circuit board 70, thus affecting the supporting effect of the support portion 2123.

[0069] In an embodiment where the distance between the two support plates 211 is adjustable, the radial cross-sectional shape of the connecting shaft 23 is prismatic, elliptical, or other non-circular. The driving wheel 2124 has a mounting hole corresponding to the radial cross-sectional shape of the connecting shaft 23. After the connecting shaft 23 is inserted and assembled into the mounting hole, the rotation of the connecting shaft 23 can drive the driving wheel 2124 to rotate.
