Description

Technical Field

[0001] This utility model relates to the field of circuit board production equipment technology, and in particular to a circuit board loading and conveying device. Background Technology

[0002] In the circuit board manufacturing process, some production stages require transporting multiple circuit boards within a single circuit board carrier. This involves transporting empty and fully loaded carriers. Current technologies often employ linear conveying along a single plane, resulting in significant space waste. For example, in limited production workshops, equipment occupies a large area, but vertical space is not effectively utilized, increasing the company's site rental or construction costs. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to design a circuit board loading and conveying device that can improve the utilization rate of site space.

[0004] The objective of this utility model is achieved through the following technical solution: A circuit board loading and conveying device is designed, including a first conveyor line and a second conveyor line arranged parallel to each other at intervals, and a lifting docking assembly located at the same end of the first conveyor line and the second conveyor line. The lifting docking assembly includes a lifting unit and a third conveyor line placed on the lifting unit. The lifting unit can drive the third conveyor line to rise and fall to dock with the first conveyor line and the second conveyor line. The third conveyor line is provided with a carrier positioning unit, which is used to restrict the movement of the circuit board carrier on the third conveyor line.

[0005] In this solution, a double-layer parallel conveyor line achieves a three-dimensional logistics layout, reducing equipment footprint. The lifting docking component dynamically connects conveyor layers of different heights via the lifting movement of the third conveyor line, enabling cross-layer material transfer without additional transfer equipment. The lifting unit and the third conveyor line are linked for control, ensuring that the circuit board carrier remains horizontally aligned with the target conveyor line during cross-layer transfer, eliminating jamming or tipping caused by height differences. By setting up a carrier positioning unit, the position of the circuit board carrier is fixed, preventing displacement of the circuit board carrier during unloading or lifting. Specifically, the first conveyor line is used to transport empty circuit board carriers, and the second conveyor line is used to transport fully loaded circuit board carriers. Empty circuit board carriers are placed on the first conveyor line manually or with automated equipment, such as robotic arms or clamping modules, and transported to the docking position with the lifting docking component. At this time, the lifting unit drives the third conveyor line to rise and dock with the first conveyor line, transferring the empty circuit board carrier to the third conveyor line. After the empty circuit board carrier moves into position on the third conveyor line, the carrier positioning unit limits and fixes the empty circuit board carrier to prevent movement. Subsequently, manual or automated equipment, such as robotic arms, places the processed circuit boards into the circuit board carrier until the carrier is full. Finally, the lifting unit lowers the third conveyor line to connect with the second conveyor line, and the carrier positioning unit releases the circuit board carrier. The fully loaded circuit board carrier is then transferred to the second conveyor line and transported to the next workstation. Simultaneously, during the lifting process of the third conveyor line, the carrier positioning unit ensures the stability of the fully loaded circuit board carrier during the lifting process, preventing it from shifting due to inertia or equipment vibration.

[0006] Furthermore, the carrier positioning unit includes a locking head that cooperates with the circuit board carrier, and a first drive member that can drive the locking head toward or away from the circuit board carrier.

[0007] In this scheme, the locking head and the first driving component form a closed-loop control system. The first driving component is synchronously controlled with the conveyor line PLC. After the carrier is in place, the locking head is immediately driven to insert into the corresponding lock hole of the circuit board carrier, thereby realizing the rapid locking of the circuit board carrier.

[0008] Furthermore, the third conveyor line includes a third conveyor belt, and two carrier positioning units are provided, which are symmetrically arranged on both sides of the width direction of the third conveyor belt.

[0009] In this design, the symmetrically arranged vehicle positioning units can be locked simultaneously from both sides of the circuit board vehicle, avoiding the problem of tilting that can easily occur when locking from one side.

[0010] Furthermore, the locking head is conical at the end near the circuit board carrier.

[0011] In this design, the conical locking head has an automatic guiding function, which can compensate for the positional error of the circuit board carrier and still effectively dock even when the position of the circuit board carrier is slightly off.

[0012] Furthermore, guide strips are symmetrically arranged on both sides of the width direction of the third conveyor belt, and the spacing between the two guide strips is adjustable.

[0013] In this solution, the adjustable guide bar plays a guiding and limiting role during the movement of the circuit board carrier. By physically limiting the lateral displacement of the circuit board carrier, it prevents the circuit board carrier from tilting.

[0014] Furthermore, the third conveyor line also includes a third frame, and the guide bar includes a fixing part and a guiding part. The fixing part is provided with a plurality of U-shaped notches, and the fixing part is fixed to the third frame by fasteners passing through the U-shaped notches.

[0015] In this solution, the U-shaped notch design allows the guide bar to slide continuously in the horizontal direction. After being locked by fasteners, precise position adjustment can be achieved. This structure can be adapted to circuit board carriers of different widths, and production line specifications can be quickly switched without changing hardware.

[0016] Furthermore, the guide portions of the two guide bars are configured with a flared structure at the port near the first conveyor line, and the opening of the flared structure gradually narrows towards the first conveyor line.

[0017] In this design, the tapered horn-shaped structure (opening towards the first conveyor line) forms a V-shaped guide channel, which can automatically correct the positional deviation of the circuit board carrier and avoid jamming or impact caused by misalignment.

[0018] Furthermore, the guide array is provided with multiple guide wheels.

[0019] In this solution, guide wheels are used to reduce friction between the circuit board carrier and the guide part, thereby reducing wear on both and increasing their service life.

[0020] Furthermore, the third conveyor line is also equipped with a positioning sensor for sensing the position of the circuit board carrier.

[0021] In this solution, the position sensing device (such as a proximity switch / photoelectric sensor) can detect the position in real time when the circuit board carrier enters the third conveyor line. After receiving the feedback position signal, the third conveyor line stops conveying, thereby enabling the carrier positioning unit to limit and fix the empty circuit board carrier to prevent it from moving.

[0022] Furthermore, the lifting unit includes a lifting platform for supporting the third conveyor line, a lead screw threaded to one side of the lifting platform, a guide rod located beside the lead screw and slidably connected to the lifting platform, and a lead screw drive for driving the lead screw to rotate.

[0023] In this solution, the lifting unit, driven by a lead screw and guided by a guide rod, offers advantages such as precise positioning, stable operation, and high load-bearing capacity, making it suitable for scenarios requiring high conveying accuracy and stability. The lifting platform is the core component of the third conveyor line; the lead screw is threaded to one side of the lifting platform, driving the lifting motion through rotation; the guide rod, located beside the lead screw, is slidably connected to the lifting platform, providing stable guidance. The guide rod and lead screw form a double-rail constraint, limiting lateral displacement through a high-precision linear guide rail to prevent tilting and jamming during lifting; the lead screw drive provides the power for the lead screw's rotation.

[0024] Compared with the prior art, the beneficial effects of this utility model are: In this solution, a double-layer parallel conveyor line achieves a three-dimensional logistics layout, reducing equipment footprint. The lifting docking component dynamically connects conveyor layers of different heights via the lifting movement of the third conveyor line, enabling cross-layer material transfer without additional transfer equipment. The lifting unit and the third conveyor line are linked for control, ensuring that the circuit board carrier remains horizontally aligned with the target conveyor line during cross-layer transfer, eliminating jamming or tipping caused by height differences. By setting up a carrier positioning unit, the position of the circuit board carrier is fixed, preventing displacement of the circuit board carrier during unloading or lifting. Specifically, the first conveyor line is used to transport empty circuit board carriers, and the second conveyor line is used to transport fully loaded circuit board carriers. Empty circuit board carriers are placed on the first conveyor line manually or with automated equipment, such as robotic arms or clamping modules, and transported to the docking position with the lifting docking component. At this time, the lifting unit drives the third conveyor line to rise and dock with the first conveyor line, transferring the empty circuit board carrier to the third conveyor line. After the empty circuit board carrier moves into position on the third conveyor line, the carrier positioning unit limits and fixes the empty circuit board carrier to prevent movement. Subsequently, manual or automated equipment, such as robotic arms, places the processed circuit boards into the circuit board carrier until the carrier is full. Finally, the lifting unit lowers the third conveyor line to connect with the second conveyor line, and the carrier positioning unit releases the circuit board carrier. The fully loaded circuit board carrier is then transferred to the second conveyor line and transported to the next workstation. Simultaneously, during the lifting process of the third conveyor line, the carrier positioning unit ensures the stability of the fully loaded circuit board carrier during the lifting process, preventing it from shifting due to inertia or equipment vibration.

[0031] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0032] like Figure 1 and 2 As shown in the figure, this embodiment provides a circuit board loading and conveying device, including a first conveying line 1 and a second conveying line 2 arranged parallel to each other at intervals, and a lifting docking assembly 3 located at the same end of the first conveying line 1 and the second conveying line 2. The lifting docking assembly 3 includes a lifting unit 31 and a third conveying line 32 placed on the lifting unit 31. The lifting unit 31 can drive the third conveying line 32 to rise and fall to dock with the first conveying line 1 and the second conveying line 2. The third conveying line 32 is provided with a carrier positioning unit 321, which is used to restrict the movement of the circuit board carrier 4 on the third conveying line 32.

[0033] It should be noted that in this embodiment, both the first conveyor line 1 and the second conveyor line 2 can be belt conveyors or chain conveyors, arranged in a double-layered configuration on a frame. Specifically, taking the first conveyor line 1 as an example, the first conveyor line 1 includes a first driving roller 11 and a first driven roller 12 rotatably mounted on the frame, and a first conveyor belt 13 sleeved between the first driving roller 11 and the first driven roller 12. The first driving roller 11 is driven by a first drive motor, thereby realizing the rotation of the first conveyor belt 13. Furthermore, the length of the first conveyor line 1 is selected according to actual conditions. When the length of the first conveyor line 1 is long, a segmented design can be adopted, i.e., a combination of multiple power segments can be used. Additionally, the first conveyor line 1 is used to convey empty circuit board carriers 4, and the second conveyor line is used to convey fully loaded circuit board carriers 4.

[0034] The third conveyor line 32 is a belt conveyor line, including a third frame 324, a third driving roller 326 and a third driven roller 327 rotatably mounted on the third frame 324, and a third conveyor belt 322 sleeved between the third driving roller 326 and the third driven roller 327. The third driving roller 326 is driven by a third drive motor 328, thereby realizing the rotation of the third conveyor belt 322. The third conveyor line 32 is used to dock with the first conveyor line 1 to transfer empty circuit board carriers 4, and to dock with the second conveyor line 2 after the empty circuit board carriers 4 are fully loaded to transfer fully loaded circuit board carriers 4. The length of the third conveyor line 32 is relatively short, only about 1.5 times the length of the circuit board carriers 4.

[0035] In practical use, the first conveyor line 1 is used to transport empty circuit board carriers 4, and the second conveyor line 2 is used to transport fully loaded circuit board carriers 4. Empty circuit board carriers 4 are placed on the first conveyor line 1 manually or using automated equipment, such as robotic arms or clamping modules, and transported to the position where they dock with the lifting and docking assembly 3. At this time, the lifting unit 31 drives the third conveyor line 32 to rise and dock with the first conveyor line 1, transferring the empty circuit board carrier 4 onto the third conveyor line 32. After the third conveyor line 32 moves into position, the carrier positioning unit 321 limits and fixes the empty circuit board carrier 4 to prevent it from moving. Subsequently, manually or using automated equipment, such as robotic arms, the processed circuit boards are placed into the circuit board carrier 4 until the circuit board carrier 4 is fully loaded. Finally, the lifting unit 31 drives the third conveyor line 32 to descend and dock with the second conveyor line 2, and the carrier positioning unit 321 releases the circuit board carrier 4. The fully loaded circuit board carrier 4 is then transferred to the second conveyor line 2 and transported to the next workstation.

[0036] like Figure 3 and 4As shown, the carrier positioning unit 321 includes a locking head 3211 that cooperates with the circuit board carrier 4, and a first driving member 3212 that can drive the locking head 3211 closer to or further away from the circuit board carrier 4. Specifically, the locking head 3211 and the first driving member 3212 form a closed-loop control system. The first driving member 3212 is synchronously controlled with the conveyor line PLC. The circuit board carrier 4 is provided with a locking hole. After it moves to a predetermined position, the first driving member 3212 drives the locking head 3211 closer to the circuit board carrier 4 to insert into the locking hole of the circuit board carrier 4, thereby realizing the rapid locking of the circuit board carrier 4. In this embodiment, the first driving member 3212 is a driving cylinder, and the end of the locking head 3211 near the circuit board carrier 4 is conical. The conical locking head 3211 has an automatic guiding function, which can compensate for the positional error of the circuit board carrier 4, and can still effectively dock even when there is a slight deviation in the position of the circuit board carrier 4. Two carrier positioning units 321 are provided, symmetrically arranged on both sides of the width direction of the third conveyor belt 322. The symmetrically arranged carrier positioning units 321 can lock simultaneously from both sides of the circuit board carrier 4, avoiding the problem of tilting that is easily caused by locking on one side. In other possible embodiments, four carrier positioning units 321 may also be provided to lock the four corners of the circuit board carrier 4.

[0037] like Figure 4 and 5 As shown, guide bars 323 are symmetrically arranged on both sides of the width direction of the third conveyor belt 322, and the spacing between the two guide bars 323 is adjustable. The adjustable guide bars 323 play a guiding and limiting role during the movement of the circuit board carrier 4, physically limiting the lateral displacement of the circuit board carrier 4 and preventing the circuit board carrier 4 from tilting. Specifically, the guide bar 323 includes a fixing part 3231 and a guiding part 3232. The fixing part 3231 is provided with multiple U-shaped notches 3233, and the fixing part 3231 is fixed to the third frame 324 by fasteners passing through the U-shaped notches 3233. The U-shaped notches 3233 design allows the guide bar 323 to slide continuously in the horizontal direction. After being locked by fasteners, precise position adjustment can be achieved. This structure can adapt to circuit board carriers 4 of different widths, and production line specifications can be quickly switched without changing hardware.

[0038] Furthermore, the guide portions 3232 of the two guide bars 323 are constructed with a flared structure at the port near the first conveyor line 1, with the opening of the flared structure gradually narrowing towards the first conveyor line 1. The flared-mouth tapering structure (opening towards the first conveyor line) forms a V-shaped guide channel, which can automatically correct the positional deviation of the circuit board carrier 4 and avoid jamming or impact caused by misalignment.

[0039] Furthermore, the guide section 3232 array is provided with multiple guide wheels (not shown in the figure). The guide wheels can be made using existing technology. By setting the guide wheels, the friction between the circuit board carrier 4 and the guide section 3232 is reduced, thereby reducing wear on both and improving service life.

[0040] like Figure 4 As shown, the third conveyor line 32 is also equipped with a position sensor 325 for sensing the position of the circuit board carrier 4. The position sensor 325 adopts a proximity switch or a photoelectric sensor, which can detect the position in real time when the circuit board carrier 4 enters the third conveyor line 32. After receiving the feedback position signal, the third conveyor line 32 stops conveying, thereby causing the carrier positioning unit 321 to limit and fix the empty circuit board carrier 4 to prevent it from moving.

[0041] like Figure 2 and 3 As shown, the lifting unit 31 includes a lifting platform 311 for carrying the third conveyor line 32, a lead screw 312 threadedly connected to one side of the lifting platform 311, a guide rod 313 located beside the lead screw 312 and slidably connected to the lifting platform 311, and a lead screw drive member 314 for driving the lead screw 312 to rotate.

[0042] In this embodiment, the lifting unit 31, driven by a lead screw 312 and a guide rod 313, possesses advantages such as precise positioning, stable operation, and strong load-bearing capacity, making it suitable for scenarios requiring high conveying accuracy and stability. The lifting platform 311 is the core component of the third conveyor line 32; the lead screw 312 is threadedly connected to one side of the lifting platform 311, driving the lifting motion through rotation; two guide rods 313 are provided, located on either side of the lead screw 312, and slidably connected to the lifting platform 311, providing stable guidance. The guide rods 313 and the lead screw 312 form a double-rail constraint, limiting lateral displacement through a high-precision linear guide rail to prevent tilting and jamming during lifting; the lead screw drive component 314 uses a drive motor with an integrated gearbox. Its output end can be directly connected to the lead screw 312 via a coupling, or connected to the lead screw 312 via a belt or chain, providing rotational power to the lead screw 312.

[0043] In this embodiment, the double-layer parallel conveyor line realizes a three-dimensional logistics layout, reducing the equipment footprint. The lifting docking component 3 dynamically connects conveyor layers of different heights through the lifting movement of the third conveyor line 32, completing cross-layer material transfer without additional transfer equipment. The lifting unit 31 is linked with the third conveyor line 32 to ensure that the circuit board carrier 4 remains horizontally aligned with the target conveyor line during cross-layer transfer, eliminating material jamming or overturning caused by height differences. By setting the carrier positioning unit 321, the position of the circuit board carrier 4 is fixed, preventing the circuit board carrier 4 from shifting during material feeding or lifting. Specifically, the first conveyor line 1 is used to transport empty circuit board carriers 4, and the second conveyor line 2 is used to transport fully loaded circuit board carriers 4. Empty circuit board carriers 4 are placed on the first conveyor line 1 manually or using automated equipment, such as robotic arms or clamping modules, and transported to the position where they dock with the lifting and docking assembly 3. At this time, the lifting unit 31 drives the third conveyor line 32 to rise and dock with the first conveyor line 1, transferring the empty circuit board carrier 4 onto the third conveyor line 32. After the third conveyor line 32 moves into position, the carrier positioning unit 321 limits and fixes the empty circuit board carrier 4 to prevent it from moving. Subsequently, manually or using automated equipment, such as robotic arms, the processed circuit boards are placed into the circuit board carrier 4 until the circuit board carrier 4 is fully loaded. Finally, the lifting unit 31 drives the third conveyor line 32 to descend and dock with the second conveyor line 2, and the carrier positioning unit 321 releases the circuit board carrier 4. The fully loaded circuit board carrier 4 is then transferred to the second conveyor line 2 and transported to the next workstation.
