[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0023] Please refer to Figures 1 to 3 This embodiment provides a circuit board assembly production line docking station, comprising a machine frame and an operating module mounted on the machine frame. The operating module is capable of completing, but not limited to, conveying circuit boards 70 between adjacent devices in the production line. The operating module is powered by an external power supply to achieve operation.

[0024] The operation module includes a conveying mechanism 20, a board inlet sensor 92, a board outlet sensor 94, and a control unit 50. Of course, the operation module also includes other commonly used components, such as an electronic control system, a heat dissipation system, and other components commonly used in the prior art, which will not be described in detail here.

[0025] The conveying mechanism 20 is used to convey the circuit board 70. The circuit board 70 enters from the board input end 201 of the conveying mechanism 20 and moves out from the board output end 202. Therefore, it can be considered that the conveying direction of the conveying mechanism 20 is from the board input end 201 to the board output end 202. The conveying direction appearing below should also be understood in this way.

[0026] The position of the board inlet sensor 92 corresponds to the position of the board inlet end 201 of the conveying mechanism 20. It is used to sense the circuit board 70 on the board inlet end 201 of the conveying mechanism 20 and generate a corresponding board inlet signal. The position of the board outlet sensor 94 corresponds to the position of the board outlet end 202 of the conveying mechanism 20. It is used to sense the circuit board 70 on the board outlet end 202 of the conveying mechanism 20 and generate a corresponding board outlet signal. The control unit 50 controls the conveying mechanism 20 to start conveying the circuit board 70 after receiving the board inlet signal fed back by the board inlet sensor 92, and controls the conveying mechanism 20 to stop conveying the circuit board 70 after receiving the board outlet signal fed back by the board outlet sensor 94.

[0027] The working process of the circuit board assembly production line docking station includes: the control unit 50 sends a board delivery instruction to the equipment at the previous station, such as a board loader, and the equipment at the previous station starts based on the board delivery instruction and delivers the circuit boards 70 to the conveying mechanism 20 piece by piece; when the circuit board 70 is conveyed to the board feed end 201 of the conveying mechanism 20, the board feed sensor 92 senses the circuit board 70 and generates a board feed signal, and feeds the board feed signal back to the control unit 50, and the control unit 50 controls the conveying mechanism 20 to start, and the conveying mechanism 20 delivers the circuit board 70 from the conveying mechanism 20 The board input end 201 is sent to the board output end 202 of the conveying mechanism 20 until the board output sensor 94 senses the circuit board 70 and generates a board output signal. The board output sensor 94 feeds back the board output signal to the control unit 50. The control unit 50 controls the conveying mechanism 20 to stop conveying the circuit board 70, so that the circuit board 70 stays on the conveying mechanism 20. Subsequently, according to the production line rhythm requirements, the next workstation sends a feeding instruction to the control unit 50 or the control unit 50 spontaneously controls the start of the conveying mechanism 20, and the conveying mechanism 20 conveys the circuit board 70 to the equipment of the next workstation. In summary, compared with the prior art, the shuttle machine of the present invention can adjust the timing of conveying the circuit board 70 according to the working rhythm of the production line, so that the process of the shuttle machine conveying the circuit board 70 can adapt to the working rhythm of the production line, and has better adaptability.

[0028] In one embodiment, both the inlet sensor 92 and the outlet sensor 94 are non-contact inductive switches. These sensors can sense the circuit board 70 without contacting it, preventing them from interfering with the conveying mechanism 20's conveying of the circuit board 70. Specifically, the inlet sensor 92 and / or the outlet sensor 94 are proximity switches, such as photoelectric sensors. Preferably, the inlet sensor 92 and / or the outlet sensor 94 are background-suppressing photoelectric sensors. Background-suppressing photoelectric sensors can reduce color interference from the circuit board 70 itself, and their detection capabilities are largely unaffected by the color of the circuit board 70 itself, thus enabling detection of circuit boards 70 of varying colors.

[0029] In one embodiment, the board inlet sensor 92 is located below the board inlet end 201 of the conveyor mechanism 20 and is spaced apart from the board inlet end 201 of the conveyor mechanism 20. The board outlet sensor 94 is located below the board outlet end 202 of the conveyor mechanism 20 and is spaced apart from the board outlet end 202 of the conveyor mechanism 20. The board inlet sensor 92 and the board outlet sensor 94 can sense the circuit boards 70 without contacting the circuit boards 70, thereby preventing the board inlet sensor 92 and the board outlet sensor 94 from interfering with the conveyor mechanism 20 in conveying the circuit boards 70.

[0030] Please combine Figure 3 In one embodiment, the machine frame 10 includes a shell, and the conveying mechanism 20 is arranged in the shell. The shell can play a dustproof and protective role, and to a certain extent can prevent external dust and impurities from contaminating the circuit board 70, and prevent external foreign objects from hitting the circuit board 70. The shell is provided with a symmetrically arranged board inlet window 14 and a board outlet window 15. The board inlet end 201 of the conveying mechanism 20 extends from the board inlet window 14 to the outside of the shell, and the board outlet end 202 of the conveying mechanism 20 extends from the board outlet window 15 to the outside of the shell. In this way, the board inlet end 201 and the board outlet end 202 of the conveying mechanism 20 can more conveniently dock with the equipment of the previous station and the equipment of the next station respectively.

[0031] In one embodiment, the board inlet sensor 92 is connected to the inner wall of the shell and is located below the board inlet window 14 ; the board outlet sensor 94 is connected to the inner wall of the shell and is located below the board outlet window 15 .

[0032] In an optional embodiment, a first connecting seat 91 and a second connecting seat 93 are provided in the machine frame 10. Specifically, the first connecting seat 91 and the second connecting seat 93 are fixed to the bottom of the board inlet window 14 and the bottom of the board outlet window 15 respectively by fasteners.

[0033] Please combine Figure 4 and Figure 5The first connecting seat 91 defines a first slot 911. Specifically, the first slot 911 extends perpendicular to the conveying direction of the conveyor mechanism 20 and parallel to the conveying surface of the conveyor mechanism 20. First, inwardly protruding first blocks 925 are symmetrically positioned on the inner walls of the two opposing notches of the first slot 911. The plate feed sensor 92 includes a first sensor 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 disposed within the first slide groove 911 and is slidable along 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 positioned between the first linear spring 922 and the first slide groove 911. Under the deforming elastic force of the first linear spring 922, the first washer 924 abuts against the edge of the notch of the first slide groove 911, and the first end cap 923 abuts against two first latches 925. This structural solution makes the position of the board infeed sensor 92 adjustable, suitable for sensing circuit boards 70 of different batches and models. When the position of the plate entry sensor 92 needs to be adjusted, it is only necessary to manually push the first washer 924 with a tool, so that the first washer 924 overcomes the deformation elastic force of the first linear spring 922 and moves toward the first sensing body 921, so that the first washer 924 is separated 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, and then the first washer 924 is released, and the deformation elastic force of the first linear spring 922 pushes the first washer 924 toward the first slide groove 911, so that the first washer 924 abuts against the first slide groove 911, and the relative position of the plate entry sensor 92 and the first slide groove 911 is determined by the friction force between the first washer 924 and the first slide groove 911 and the friction force between the first end cap 923 and the two first blocks 925.

[0034] The structure of the second connecting seat 93 is similar to that of the first connecting seat 91 , and the structure of the board-out sensor 94 is similar to that of the board-in sensor 93 . In this embodiment, the specific structures of the second connecting seat 93 and the board-out sensor 94 are not illustrated in detail.

[0035] The second connecting seat 93 defines a second chute, extending parallel to the direction of the first chute 911. The inner walls of the two opposing notches of the second chute are symmetrically provided with inwardly protruding second latches. The board-out sensor 94 comprises 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, which is slidable along the second chute. The second washer and the second linear spring are sleeved on the second connecting rod, and the second washer is located between the second linear spring and the second chute. Under the deformation force of the second linear spring, the second washer abuts the edge of the notch of the second chute, and the second end cap abuts the two second latches. The aforementioned structural scheme makes the position of the board-out sensor 94 adjustable, suitable for sensing different batches and models of circuit boards 70. The adjustment principle of the board-out sensor 94 is similar to that of the board-in sensor 92, and the adjustment principle of the board-out sensor 94 will not be elaborated here.

[0036] See also Figures 6 to 12 In one embodiment, the conveying mechanism 20 includes two support plates 211 symmetrically arranged on the machine frame, two conveyor belts 21 respectively arranged 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 the two sides of the circuit board 70 respectively. Under the drive of the drive assembly 22, the two conveyor belts 21 act synchronously on the two sides of the circuit board 70 to push the circuit board 70 forward. The above-mentioned structural solution can form an avoidance space between the two conveyor belts 21 to avoid the components on the bottom surface of the circuit board 70. The board inlet sensor 92 and the board outlet sensor 93 are both located between the two conveyor belts 21. The board inlet sensor 92 and the board outlet sensor 93 sense the lower surface of the circuit board 70 from bottom to top, thereby increasing the area of ​​the circuit board 70 that can be sensed. Therefore, the board inlet sensor 92 and the board outlet sensor 93 can sense the circuit board 70 more accurately.

[0037] In one embodiment, the conveyor belt 21 includes a pulley assembly mounted on a support plate 211 and an interlocking belt 2122 mounted on the pulley assembly. The interlocking belt 2122, constrained by the pulley assembly, forms a support portion 2123 extending along the conveying direction of the conveyor mechanism 20. The support portion 2123 supports the circuit board 70. The drive assembly 22 simultaneously drives the pulley assemblies of both conveyor belts 21 via an interlocking shaft 23, so that the pulley assembly drives the interlocking belt 2122 to transport the circuit board 70.

[0038] In one embodiment, the pulley assembly 212 includes a driving pulley 2124, two driven pulleys 2121, and a plurality of tensioning pulleys 2125. The two driven pulleys 2121 are located at either end of the abutment platform 2112, and the two driven pulleys 2121 limit the position of the interlocking belt 2122, thereby forming a support portion 2123. Each tensioning pulley 2125 is located below the driven pulleys 2121 and is used to provide tension to the interlocking belt 2122. The two ends of the interlocking shaft 23 are rotatably connected to the two support plates 211. The driving pulleys 2124 of the two pulley assemblies are sleeved on the interlocking shaft 23. When the interlocking shaft 23 rotates, the driving pulleys 2124 of the two pulley assemblies rotate synchronously.

[0039] Regarding the installation method of the two support plates 211, there are the following implementation methods: In one embodiment (not shown), both support plates 211 may be fixedly connected to the machine frame 10 , and the distance between the two support plates 211 is not adjustable. As for how the support plates 211 are fixedly connected to the machine frame 10 , there is no limitation here.

[0040] 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 built-in plate 11 and a second built-in plate 12 are provided inside the machine frame 10. The first built-in plate 11 and the second built-in plate 12 are fixedly connected to the inner wall of the machine frame 10 by fasteners, and the bottoms of the first built-in plate 11 and the second built-in plate 12 are connected by a 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 provided 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 closer to the first built-in plate 11 is fixedly connected to the first built-in plate 11 by fasteners and cannot slide relative to the guide rods 81. The support plate 211 close to the second inner plate 12 can slide back and forth relative to the guide rod 81 along the axial direction of the guide rod 81 .

[0041] Furthermore, the distance between the two support plates 211 can be adjusted by a screw mechanism. Specifically, the screw mechanism includes a screw shaft 80, a screw sleeve and a screw motor. The two ends of the screw shaft 80 pass through the first built-in plate 11 and the second built-in plate 12 respectively, and are rotatably connected to the first built-in plate 11 and the second built-in plate 12 respectively. The screw motor is fixed to the side of the first built-in plate 11 facing away from the support plate 211, and its rotating shaft is connected to the screw rotating shaft through a shaft coupling component. The screw sleeve is sleeved on the screw shaft 80 and is threadedly connected to the screw shaft 80. The support plate 211 close to the first built-in plate 11 is fixedly connected to the screw sleeve. Specifically, the screw sleeve is inserted into the corresponding support plate 211 and is fixedly connected to the support plate 211 through fasteners. When the lead screw motor drives the lead screw shaft 80 to rotate forward and reverse, the lead screw shaft 80 forces the lead screw sleeve to reciprocate along the axial direction of the lead screw shaft 80, thereby driving the corresponding support plate 211 away from and toward 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 application scenarios, the distance between the two conveyor belt 21 brackets can be adjusted using the aforementioned method, so that the conveying mechanism 20 can adapt to conveying circuit boards 70 of different widths.

[0042] 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 that of the previous embodiment in that the screw mechanism includes two screw sleeves, the internal threads of which rotate in opposite directions. The two support plates 211 are respectively fixedly connected to the two screw sleeves. When the screw motor drives the screw shaft 80 to rotate, the screw shaft 80 drives the two screw shaft sleeves 80 to move closer to and away from each other, thereby driving the two support plates 211 closer to and away from each other.

[0043] Next, the structure of the support plate 211 is further exemplified.

[0044] In one embodiment, an abutment platform 2112 is protruding 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 the bottom surface of the support portion 2123 to provide support for the support portion 2123, thereby preventing the support portion 2123 from being deformed by the downward pressure of the circuit board 70, which would affect the supporting effect of the support portion 2123.

[0045] In the embodiment where the distance between the two support plates 211 is adjustable, the radial cross-section of the linkage shaft 23 is prismatic, elliptical, or other non-circular shapes, and the driving wheel 2124 is provided with an assembly hole corresponding to the radial cross-section of the linkage shaft 23. After the linkage shaft 23 is inserted into and assembled with the assembly hole, the rotation of the linkage shaft 23 drives the driving wheel 2124 to rotate, and the linkage shaft 23 and the driving wheel 2124 can move relative to each other in the axial direction of the linkage shaft 23. This design allows the screw mechanism to drive the support plate 211 and the driving wheel 2124 to move axially along the linkage shaft 23, while also allowing the linkage shaft 23 to drive the driving wheel 2124.

[0046] Next, an example explanation will be given of how the driving assembly 22 drives the interlocking belt 2122 .

[0047] In one embodiment, the drive assembly 22 includes a drive motor and a coupling. The drive motor is secured to the machine frame 10 via fasteners. Specifically, the drive motor is secured to the side of the first internal plate 11 facing away from the support plate 211 via fasteners. The drive motor's rotating shaft is coaxially connected to the linkage shaft 23 via the coupling. The drive motor drives the linkage shaft 23 to rotate, which in turn drives the driving pulleys 2124 of the two belt assemblies to rotate synchronously.
