However, current transfer stations primarily function as circuit board transporters, making their functionality relatively limited and hindering improvements in production line efficiency and cost savings.

The output sensor is linearly reciprocating and slidingly disposed on the second connecting seat. The movement trajectory of the output sensor is parallel to the movement trajectory of the feed sensor.

[0010] In one optional embodiment, the machine frame includes a housing with symmetrically arranged inlet and outlet windows; a conveying mechanism is disposed inside the housing, with the inlet end of the conveying mechanism extending from the inlet window to the outside of the housing, and the outlet end of the conveying mechanism extending from the outlet window to the outside of the housing; an inlet sensor is located below the inlet window; and an outlet sensor is located below the outlet window.

[0011] In one optional embodiment, the machine frame includes two mounting bases; the housing has an upper cavity and a lower cavity arranged in an upward and downward direction; an inlet window and an outlet window are opened in the upper cavity; a bottom window penetrating the lower cavity is opened in the bottom wall of the upper cavity, and the bottom window is provided with a removable baffle plate to close the bottom window; the two mounting bases are respectively fixed to the inner walls of the upper cavity and the lower cavity; a conveying mechanism is disposed in the upper cavity; the label scanning device is detachably mounted on one of the two mounting bases; when the label scanning device is mounted on the mounting base in the upper cavity, the label scanning device is located above the conveying mechanism; when the label scanning device is mounted on the mounting base in the lower cavity, the label scanning device is located below the conveying mechanism and directly facing the bottom window.

[0012] In one optional embodiment, the mounting base is provided with a slide groove; the label scanning device includes a scanning body, a connecting frame and a slider, the slider can slide back and forth linearly in the slide groove, the trajectory of the slider is parallel to the transmission surface of the conveying mechanism and perpendicular to the conveying direction of the conveying mechanism; the scanning body is set on the slider through the connecting frame and can slide together with the slider.

[0013] In one optional 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; the orthographic projections formed by the brush mechanism, foreign object sensor, and label scanning device on the conveying surface of the conveying mechanism are located between the two conveyor belts; the first orthographic projection and the second orthographic projection are located between the two conveyor belts.

[0014] In one optional 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 simultaneously drives the pulley assemblies of the two conveyor belts through a connecting shaft, so that the pulley assemblies drive the connecting belt to convey the circuit board; the inner sidewall of the support plate is provided with an abutment platform, which 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 assembly 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 respectively; the driving pulleys of the two pulley assemblies 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 rotating 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.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the board infeed sensor forms a first orthographic projection on the conveying surface of the conveying mechanism, and the board outfeed sensor forms a second orthographic projection on the same surface. The orthographic projections of the brush mechanism, foreign object sensor, and label scanning device on the conveying surface are located between the first and second orthographic projections. Therefore, during the conveying process, the circuit board first passes through the position corresponding to the board infeed sensor, then through the positions corresponding to the brush mechanism, foreign object sensor, and label scanning device, and finally through the position corresponding to the foreign object sensor.

[0016] When the circuit board is transported from the previous station to the board feeding end of the conveying mechanism, the circuit board is first detected by the board feeding sensor. The board feeding sensor generates a board feeding signal. When the control unit receives the board feeding signal fed back by the board feeding sensor, it controls the conveying mechanism to start transporting the circuit board and controls the label scanning device to start scanning the label of the circuit board, thus realizing the function of scanning the circuit board label during the transport of the circuit board.

[0017] During the conveying process of the circuit board, the brush mechanism cleans foreign objects from the surface of the circuit board, thus achieving the function of cleaning the circuit board.

[0018] After the brush mechanism cleans the surface of the circuit board, the foreign object sensor detects whether there are any foreign objects on the surface of the circuit board. After receiving the signal from the foreign object sensor that there are foreign objects, the control unit can control the conveying mechanism to stop conveying the circuit board so that the foreign objects on the surface of the circuit board can be cleaned manually. This is how the foreign object detection function is realized.

[0019] When the circuit board is finally delivered to the output end of the conveying mechanism, the control unit receives the output signal from the output sensor and controls the conveying mechanism to stop delivering the circuit board. When the control unit receives the output command from the next station equipment, it controls the conveying mechanism to send the circuit board to the next station equipment. Through the above scheme, the board storage function is realized so as to coordinate with the working rhythm of the next station equipment.

[0020] In summary, the solution of this utility model can realize the function of conveying circuit boards. Furthermore, during the conveying process, it can perform functions such as foreign object cleaning, foreign object monitoring, and label scanning of circuit boards without stopping the machine. In addition, after cleaning and scanning the circuit boards, it can also store them. Compared with the prior art, the solution of this utility model can achieve more functions, thus better adapting to production line needs. Attached Figure Description

[0027] Please combine Figures 1 to 4 This embodiment provides a multifunctional circuit board assembly docking station, including a machine frame 10 and an operation module disposed on the machine frame 10. The operation module is capable of performing processes including but not limited to the transport of circuit boards 70 to adjacent equipment in the production line. The operation module is powered by an external power supply to enable operation.

[0028] The operating module includes a conveying mechanism 20, a brush mechanism 30, a foreign object sensor 40, an infeed sensor 92, an outfeed sensor 94, a label scanning device 90, and a control unit 50. Of course, the operating module also includes other commonly used components, such as electronic control systems and heat dissipation systems, which are commonly used in existing technologies. These commonly used components will not be described in detail here.

[0029] The conveying mechanism 20 is used to convey the circuit board 70. The circuit board 70 enters from the board inlet end 201 of the conveying mechanism 20 and exits from the board outlet end 202. Therefore, it can be assumed that the conveying direction of the conveying mechanism 20 is from the board inlet end 201 to the board outlet end 202. The conveying direction mentioned below should also be understood in this way.

[0030] The brush mechanism 30 is located above the conveying mechanism 20 and is used to clean foreign objects from the surface of the circuit board 70 during the conveying process of the conveying mechanism 20. These foreign objects may be components, packaging materials, dust and impurities, and other solid substances that may affect the subsequent processing.

[0031] The foreign object sensor 40 is used to sense foreign objects on the surface of the circuit board 70 after the brush mechanism 30 has cleaned them.

[0032] The board feed sensor 92 is positioned corresponding to the board feed end 201 of the conveying mechanism 20. It is used to sense the circuit board 70 on the board feed end 201 of the conveying mechanism 20 and generate a corresponding board feed signal. The board output sensor 94 is positioned corresponding to the board output end 202 of the conveying mechanism 20. It is used to sense the circuit board 70 on the board output end 202 of the conveying mechanism 20 and generate a corresponding board output signal.

[0033] The label scanning device 90 is mounted on the machine frame 10 and is used to scan the label of the circuit board 70 during the conveying process of the conveying mechanism 20, obtain the marking information contained in the label, and transmit 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 in a separate storage medium, for easy retrieval later.

[0034] The control unit 50 can be a PLC controller, an MCU processor, or other microprocessor capable of data analysis, processing, and control functions. The control unit 50 is electrically connected to the brush mechanism 30, the label scanning device 90, the infeed sensor 92, the outfeed sensor 94, the conveying mechanism 20, and the foreign object sensor 40 via wires. The control unit 50 can receive signals and instructions from the infeed sensor 92, the outfeed sensor 94, the foreign object sensor 40, the previous station equipment, and the next station equipment, and control the conveying mechanism 20, the brush mechanism 30, and the label scanning device 90 to perform corresponding actions based on these signals and instructions.

[0035] Please combine Figure 3 , Figure 4 and Figure 5 The board infeed sensor 92 forms a first orthographic projection 301 on the conveying surface of the conveying mechanism 20, and the board outfeed sensor 94 forms a second orthographic projection 302 on the conveying surface of the conveying mechanism 20. The orthographic projections formed by the brush mechanism 30, the foreign object sensor 40, and the label scanning device 90 on the conveying surface of the conveying mechanism 20 are p1, p2, and p3, respectively. p1, p2, and p3 are located between the first and second orthographic projections. The conveying surface of the conveying mechanism 20 should be understood as the plane containing the surface portion of the conveying mechanism 20 that supports the circuit board 70 during the conveying process. In this embodiment, this plane is parallel to the lower surface of the circuit board 70. Furthermore, the relative positions of p1, p2, and p3 are not limited to... Figure 5 As shown in the figure, in other embodiments, the relative positions of the three can vary depending on the actual device design, as long as all three are located between the first orthographic projection 301 and the second orthographic projection 302.

[0036] In the aforementioned scheme, during the process of conveying the circuit board 70, the conveying mechanism 20 first passes through the position corresponding to the board entry sensor 92, then passes through the positions corresponding to the brush mechanism 30, the foreign object sensor 40 and the label scanning device 90, and finally passes through the position corresponding to the foreign object sensor 40.

[0037] The working process of the multifunctional circuit board assembly dock in this embodiment includes: S1. Control unit 50 sends a board delivery command to the equipment at the next station via a signal line. Based on the board delivery command, the equipment at the next station delivers the circuit board 70 to the board entry end 201 of the conveying mechanism 20. The board entry sensor 92 senses the circuit board 70 at the board entry end 201 and generates a board entry signal, and feeds the board entry signal back to control unit 50.

[0038] S2. After receiving the board feeding signal, the control unit 50 starts the conveying mechanism 20 to transport the circuit board 70. At the same time, after receiving the board feeding signal, the control unit 50 also starts the label scanning device 90 and the brush mechanism 30.

[0039] The label scanning device 90 operates as follows: During the transport of the circuit board 70, the label scanning device 90 scans the labels on the circuit board 70 and transmits the scan results to the control unit 50. The control unit 50 analyzes the scan results. If the scan results are normal, the scan results are converted into corresponding data and stored in its built-in or external storage medium. If the scan results are abnormal, such as no label information being scanned, incomplete labels being scanned, missing labels, or missed scans, the control unit 50 controls the transport mechanism 20 to stop transporting the circuit board 70, allowing manual inspection of the circuit board 70 for label errors. After inspection, the operator inputs a command to the control unit 50, which then controls the transport mechanism 20 to continue transporting the circuit board 70. This scheme enables the function of scanning labels on the circuit board 70. In some optional embodiments, an alarm device 60 can be set up to issue alarm information. When a label error occurs, the control unit 50 controls the alarm device 60 to issue an alarm to alert the operator. The alarm device 60 is electrically connected to the control unit 50 via a wired connection. The alarm device 60 can be a buzzer, signal light, or other device that can emit a warning signal.

[0040] The working process of the brush mechanism 30 includes: after the conveying mechanism 20 is started, the control unit 50 controls the brush mechanism 30 to start working. During the conveying process of the conveying mechanism 20 transporting the circuit board 70, the brush mechanism 30 cleans foreign objects from the upper surface of the circuit board 70. To prevent incomplete cleaning of foreign objects by the brush mechanism 30, after the brush mechanism 30 has cleaned the upper surface of the circuit board 70, the foreign object sensor 40 senses the corresponding part of the upper surface of the circuit board 70 after being cleaned by the brush mechanism 30 to monitor whether there are still foreign objects in that part. If the foreign object sensor 40 does not detect any foreign objects on the upper surface of the circuit board 70, the conveying mechanism 20 transports the circuit board 70 normally. If the foreign object sensor 40 detects foreign objects remaining on the upper surface of the circuit board 70, it sends a signal to the control unit 50 indicating the presence of foreign objects. After receiving the signal from the foreign object sensor 40, the control unit 50 can control the conveying mechanism 20 to stop transporting the circuit board 70 so that manual intervention can be performed to check and clean it, ensuring that the foreign objects remaining on the upper surface of the circuit board 70 are completely removed. After manual inspection and removal of foreign objects, the operator inputs a start command to the control unit 50 via a physical start button, causing the conveyor mechanism 20 to continue the subsequent conveying of the circuit board 70. This solution achieves the functions of cleaning the circuit board 70 and monitoring for foreign objects after cleaning. In some optional embodiments, after receiving a signal from the foreign object sensor 40 indicating the presence of a foreign object, the control unit 50 controls the alarm device 60 to issue an alarm to alert the operator.

[0041] S3. When the circuit board 70 is conveyed to the board output end 202 of the conveying mechanism 20, the board output sensor 94 senses the circuit board 70 and generates a board output signal, and feeds the board output signal back to the control unit 50. The control unit 50 controls the conveying mechanism 20 to stop conveying the circuit board 70. At this time, the circuit board 70 stays on the conveying mechanism 20, waiting for the control unit 50 to receive the board pick-up signal from the next station equipment. After that, the control unit 50 controls the conveying mechanism 20 to convey the circuit board 70 to the next station equipment. In this way, the board storage function is realized so as to coordinate with the working rhythm of the next station equipment.

[0042] When there is no circuit board 70 on the conveying mechanism 20, neither the board infeed sensor 92 nor the board outfeed sensor 94 can detect the circuit board 70. The control unit 50 cannot receive the board infeed signal and the board outfeed signal. The control unit 50 sends a board delivery command to the next station equipment so that the next station equipment can send the new circuit board 70 to the board infeed end 201 of the conveying mechanism 20 and repeat the above process.

[0043] In summary, this embodiment can achieve the functions of foreign object cleaning, foreign object monitoring, and label scanning of the circuit board 70 without stopping the machine during the conveying process of the conveying mechanism 20. In addition, after cleaning and scanning the circuit board 70, it can also realize the function of storing the board. Compared with the prior art, the solution of this utility model can realize more functions, thereby better adapting to the needs of the production line. On the other hand, it can complete the cleaning and label scanning process without stopping the machine, which is conducive to improving the efficiency of the production line.

[0044] Next, the structure and connection method of the label scanning device 90 of this application will be further illustrated by way of example.

[0045] Please combine Figure 1 , Figure 4 , Figure 6 and Figure 7 In one embodiment, the machine frame 10 includes a housing, and the conveying mechanism 20 is disposed within the housing. The housing serves as a dustproof and protective element, preventing external dust and impurities from contaminating the circuit board 70 and preventing foreign objects from impacting the circuit board 70. The housing has symmetrically arranged inlet windows 14 and outlet windows 16. The inlet end 201 of the conveying mechanism 20 extends from the inlet window 14 to the outside of the housing, and the outlet end 202 of the conveying mechanism 20 extends from the outlet window 16 to the outside of the housing. This allows the inlet end 201 and outlet end 202 of the conveying mechanism 20 to more easily connect with the equipment at the previous station and the equipment at the next station, respectively.

[0046] Furthermore, the housing is provided with an upper cavity 101 and a lower cavity 102 arranged in an upward and downward direction. The conveying mechanism 20 is located in the upper cavity, and the inlet window 14 and the outlet window 16 are located on opposite sides of the upper cavity 101. The bottom wall of the upper cavity 101 has a bottom window 1012 that passes through the lower cavity 102. The bottom window 1012 is provided with a detachable baffle 1011, which closes the bottom window 1012. Specifically, the baffle 1011 can be fixed to the upper surface of the bottom window 1012 with screws. When it is necessary to remove the baffle 1011, the screws can be unscrewed to remove the baffle 1011.

[0047] Please continue reading. Figure 6 and Figure 7 In some embodiments, the machine frame 10 further includes two mounting bases 100 ( Figure 6 and Figure 7(Only one mounting base is marked in the image). 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. 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 (e.g., ...), Figure 3 As shown), the label scanning device 90 is located 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 installed in the mounting base 100 in the lower cavity (as shown), Figure 6 As shown), the label scanning device 90 is located below the conveying mechanism 20 and directly opposite the bottom window 1012. The label scanning device 90 scans the label on the lower surface of the circuit board 70 of the conveying mechanism 20 from bottom to top through the bottom window 1012.

[0048] 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.

[0049] Please continue reading. Figure 2 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.

[0050] Please combine Figure 8 and Figure 9In 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.

[0051] 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.

[0052] 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 and lower cavities 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] Next, the structure and connection method of the brush mechanism 30 of this application will be further illustrated by way of example.

[0057] Please combine Figure 3 and Figure 10In one embodiment, the brush mechanism 30 includes a brush member for cleaning foreign objects. The brush member is located above the feed plate end 201 of the conveying mechanism 20, and the foreign object sensor 40 is disposed at the feed plate end 201 of the conveying mechanism 20. In the conveying direction of the conveying mechanism 20, the brush member is closer to the feed plate side of the conveying mechanism 20 than the foreign object sensor 40. This ensures that the monitoring action of the foreign object sensor 40 occurs after the brush member performs the cleaning action, reducing the probability of false detection by the foreign object sensor 40.

[0058] In this embodiment, the brush mechanism 30 further includes a lifting drive device 31, which is mounted on the machine frame 10. Specifically, the lifting drive device 31 is fixed to the inner wall of one of the panels of the machine frame 10 by fasteners. The brush component is located at the output end of the lifting drive device 31, which drives the brush component to move up and down. The lifting drive device 31 can be a cylinder, an electric cylinder, or other drive device capable of outputting reciprocating motion. In this embodiment, the lifting drive device 31 uses a low-cost cylinder. In some application scenarios, when it is necessary to stop the machine to remove the circuit board 70 from the conveying mechanism 20, the cylinder valve is manually operated to move the brush component upward away from the conveying mechanism 20, so that the circuit board 70 can be manually removed from the conveying mechanism 20. After the circuit board 70 is removed, the cylinder valve is manually operated to move the brush component downward to a preset working position. In addition, when the conveying mechanism 20 stops working, the cylinder also drives the brush component to move upward, so as to leave operating space above the conveying mechanism 20, which facilitates the inspection, maintenance and other operations of the conveying mechanism 20.

[0059] In some other embodiments, the lifting drive device 31 is a cylinder, and the valve switch of the cylinder is an electric control switch. The electric control switch is electrically connected to the control unit 50. The control unit 50 controls the operation of the electric control switch, thereby controlling the cylinder to move, and finally controlling the lifting drive device 31 to drive the brush mechanism 30 to move up and down.

[0060] In other embodiments, the lifting drive device 31 may be an electric cylinder (or a linear module). The electric cylinder is electrically connected to the control unit 50. The control unit 50 controls the electric cylinder to drive the brush component to move down precisely according to a preset stroke, so that the brush mechanism 30 can flexibly adjust its position according to the thickness of different circuit boards 70, ensuring that the brush mechanism 30 can be used for circuit boards 70 of different thicknesses.

[0061] In one embodiment, the brush component includes a brush handle and a brush plate 32. The brush handle is fixed to the output end of the lifting drive device 31 by fasteners. The brush plate 32 is fixed to the brush handle, with its surface perpendicular to the conveying direction of the conveying mechanism 20, and its bottom side parallel to the transmission surface of the conveying mechanism 20. The transmission surface of the conveying mechanism 20 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. When the conveying mechanism 20 conveys the circuit board 70 along its conveying direction, the bottom side of the brush plate 32 contacts the upper surface of the circuit board 70 and slides relative to the upper surface of the circuit board 70, thus sweeping foreign objects off the upper surface of the circuit board 70. The cleaning process is simple and quick. In addition, the cleaning process is synchronized with the conveying process of the conveying mechanism 20 conveying the circuit board 70, and does not affect the efficiency of the conveying mechanism 20 in conveying the circuit board 70.

[0062] In one embodiment, the brush plate 32 includes a rigid rod 321 and a bristle assembly 322. The rigid rod 321 is fixed to the brush handle by fasteners. The orthographic projection of the bristle assembly 322 onto the conveying mechanism 20 is located between the foreign object sensor 40 and the end edge of the inlet plate 201 of the conveying mechanism 20. The bristle assembly 322 can be made of filaments such as plastic filaments, cotton filaments, and feathers. The filaments of the bristle assembly 322 are fixed to the rigid rod 321 by bonding, welding, rope binding, or other suitable connection methods, and extend along the length direction of the rigid rod 321. The length of the bristle assembly 322 extending along the rigid rod 321 is greater than the width of the circuit board 70. When the lifting drive device 31 drives the brush component to move down to the preset position, the bristle assembly 322 on the rigid rod 321 contacts the top surface of the conveying mechanism 20 and the upper surface of the circuit board 70. When the bristle assembly 322 slides relative to the circuit board 70, the bristle assembly 322 can thoroughly clean the upper surface of the circuit board 70.

[0063] Next, the structure and connection of the board entry sensor 92 and the board exit sensor 94 of this application will be further described by way of example.

[0064] Please combine Figure 3 , Figure 11 as well as Figure 12In one embodiment, both the infeed sensor 92 and the outfeed sensor 94 are non-contact inductive switches. The infeed sensor 92 and the outfeed sensor 94 can sense the circuit board 70 without contacting it, thus avoiding interference with the conveying mechanism 20's transport of the circuit board 70. Specifically, the infeed sensor 92 and / or the outfeed sensor 94 are proximity switches, such as photoelectric switches. Preferably, the infeed sensor 92 and / or the outfeed sensor 94 are background suppression photoelectric sensors. Background suppression photoelectric sensors can reduce color interference from the circuit board 70 itself, and their detection capability is largely unaffected by the color of the circuit board 70, thus enabling the detection of circuit boards 70 of different colors.

[0065] In one embodiment, the board feed sensor 92 is located below and spaced apart from the board feed end 201 of the conveying mechanism 20; the board discharge sensor 94 is located below and spaced apart from the board discharge end 202 of the conveying mechanism 20. The board feed sensor 92 and the board discharge sensor 94 can sense the circuit board 70 without contacting it, thus avoiding interference with the conveying mechanism 20's transport of the circuit board 70.

[0066] In one embodiment, the inlet sensor 92 is connected to the inner wall of the housing and is located below the inlet window 14; the outlet sensor 94 is connected to the inner wall of the housing and is located below the outlet window 16.

[0067] In an optional embodiment, the machine frame is provided with a first connecting seat 91 and a second connecting seat 93. Specifically, the first connecting seat 91 and the second connecting seat 93 are respectively fixed to the bottom of the inlet window 14 and the bottom of the outlet window 16 by fasteners.

[0068] The first connecting seat 91 has a first sliding groove 911. Specifically, the direction in which the first sliding groove 911 extends is perpendicular to the conveying direction of the conveying mechanism 20 and parallel to the conveying surface of the conveying mechanism 20. The inner walls of the two opposite openings of the first sliding groove 911 are symmetrically provided with inwardly protruding first locking blocks 925. The feed plate sensor 92 includes a first sensing body 921, a first connecting rod, a first washer 924, and a first linear spring 922. One end of the first connecting rod is connected to the first sensing body 921, and the other end has a first end cap 923. The first end cap 923 is slidably disposed within the first slide groove 911. A first washer 924 and a first linear spring 922 are sleeved on the first connecting rod, with the first washer 924 located between the first linear spring 922 and the first slide groove 911. Under the deformation elastic force of the first linear spring 922, the first washer 924 abuts against the edge of the groove opening of the first slide groove 911, and the first end cap 923 abuts against the two first locking blocks 925. Through the aforementioned structural scheme, the position of the board feed sensor 92 is adjustable to be suitable for sensing circuit boards 70 of different batches and models. When the position of the feed plate sensor 92 needs to be adjusted, the first washer 924 can be manually pushed with a tool, causing the first washer 924 to overcome the deformation force of the first linear spring 922 and move towards the first sensing body 921. In this way, the first washer 924 separates from the first slide groove 911, so that the end cap of the first connecting rod can be easily pushed to slide along the first slide groove 911 to the expected position. Then, the first washer 924 is released, and the deformation force of the first linear spring 922 pushes the first washer 924 towards the first slide groove 911, so that the first washer 924 abuts against the first slide groove 911. The relative position of the feed plate sensor 92 and the first slide groove 911 is defined by the friction between the first washer 924 and the first slide groove 911, as well as the friction between the first end cap 923 and the two first locking blocks 925.

[0069] The second connecting seat 93 has a second sliding groove 110, the extension direction of which is parallel to the extension direction of the first sliding groove 911. Symmetrically arranged on the inner walls of the two opposite openings of the second sliding groove 110 are inwardly protruding second locking blocks. The board ejector sensor 94 includes a second sensing body, a second connecting rod, a second washer, and a second linear spring. One end of the second connecting rod is connected to the second sensing body, and the other end has a second end cap. The second end cap is slidably disposed within the second sliding groove 110. The second washer and the second linear spring are sleeved on the second connecting rod, with the second washer located between the second linear spring and the second sliding groove 110. Under the deformation force of the second linear spring, the second washer abuts against the edge of the opening of the second sliding groove 110, and the second end cap abuts against the two second locking blocks. Through the aforementioned structural design, the position of the board ejector sensor 94 is adjustable to accommodate sensing circuit boards 70 of different batches and models. The adjustment principle of the output sensor 94 is similar to that of the input sensor 92. Therefore, the adjustment principle of the output sensor 94 will not be elaborated here, nor will the installation scheme of the output sensor 94 be illustrated.

[0070] Please combine Figures 13 to 19 In one embodiment, the conveying mechanism 20 includes two support plates 211 symmetrically disposed on the machine frame, 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 first orthographic projection 301 of the infeed sensor 92 and the second orthographic projection 302 of the outfeed sensor 94 are located between the two conveyor belts 21. Specifically, both the infeed sensor 92 and the outfeed sensor 94 are located between the two conveyor belts 21. The infeed sensor 92 and the outfeed sensor 94 sense the lower surface of the circuit board 70 from bottom to top, increasing the area of ​​the circuit board 70 that can be sensed. Therefore, the infeed sensor 92 and the outfeed sensor 94 can sense the circuit board 70 more accurately. In addition, the orthographic projections formed on the conveying surface of the conveying mechanism 20 by the brush mechanism 30, the foreign object sensor 40, and the label scanning device 90 are also located between the two conveyor belts 21.

[0071] 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.

[0072] 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.

[0073] The following are the implementation methods for installing the two support plates 211: 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. As to how the support plates 211 are fixedly attached to the machine frame 10, no limitation is made here.

[0074] In 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, a first internal plate 11 and a second internal plate 12 are provided inside the machine frame 10. The first internal plate 11 and the second internal plate 12 are fixed to the inner wall of the machine frame 10 by fasteners, and the bottoms of the first internal plate 11 and the second internal plate 12 are connected by a base plate 13. A guide rod 81 is provided between the first internal plate 11 and the second internal plate 12, and the number of guide rods 81 can be one, two, or more. The guide rod 81 is perpendicular to the first internal plate 11 and the second internal plate 12, and its two ends are respectively connected to the first internal plate 11 and the second internal plate 12. The two support plates 211 are disposed between the first internal plate 11 and the second internal plate 12 and are sleeved on the guide rods 81. The support plate 211 closer to the first internal plate 11 is fixed to the first internal plate 11 by fasteners and cannot slide relative to the guide rods 81. The support plate 211, which is close to the second built-in plate 12, can slide back and forth relative to the guide rod 81 along the axial direction of the guide rod 81.

[0075] 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.

[0076] 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.

[0077] Next, the structure of the support plate 211 will be further illustrated by example.

[0078] 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.

[0079] 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. Furthermore, the connecting shaft 23 and the driving wheel 2124 can move relative to each other along the axial direction of the connecting shaft 23. This design allows the screw mechanism to drive the support plates 211 and the driving wheel 2124 to move along the axial direction of the connecting shaft 23, and also allows the connecting shaft 23 to drive...

[0080] Next, we will provide an exemplary description of how the drive component 22 drives the connecting belt 2122.

[0081] In one embodiment, the drive assembly 22 includes a drive motor and a coupling. The drive motor is fixed to the machine frame 10 by fasteners. Specifically, the drive motor is fixed to the side of the first built-in plate 11 facing away from the support plate 211 by fasteners. The shaft of the drive motor is coaxially connected to the connecting shaft 23 through the coupling. The drive motor drives the connecting shaft 23 to rotate, and the connecting shaft 23 drives the drive pulleys 2124 of the two belt assemblies to rotate synchronously. The drive pulleys 2124 drive the connecting belt 2122 to move, thereby causing the support portion 2123 of the connecting belt 2122 to move the circuit board 70, thus achieving the purpose of conveying the circuit board 70.

[0082] In one embodiment, the top surface of the support plate 211 has a downwardly recessed groove 2111. The foreign object sensor 40 is a photoelectric sensor, and the light-emitting element 40a and the light-receiving element 40b of the photoelectric sensor are respectively embedded in the grooves 2111 of the two support plates 211. Under the limitation of the grooves 2111, the photoelectric sensor will not easily shift its position, thus ensuring its sensing accuracy.

[0083] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0084] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
