Description

Technical Field

[0001] This application relates to the field of PCB motherboard cache library technology, and in particular to a synchronous belt-connected power belt conveyor structure. Background Technology

[0002] In the PCB motherboard manufacturing industry, after the PCB motherboards are manufactured on the SMT production line, they are all temporarily stored in a warehouse in batches. When the next stage needs the product, the mechanism will retrieve the motherboards from the warehouse. Since the warehouse has a large number of storage positions, if the conveyor belt in each storage position is designed as a powered conveyor belt, the conveyor equipment will occupy a large space in a narrow space, the structure will be more complex, and maintenance will be inconvenient. Summary of the Invention

[0003] To address the shortcomings of existing buffer storage locations where all conveyor belts are designed as powered conveyor belts, resulting in large space occupation, more complex structures, and inconvenient maintenance in narrow spaces, this application provides a synchronous belt-connected powered conveyor belt structure.

[0004] The synchronous belt-connected power belt conveyor structure provided in this application adopts the following technical solution: A synchronous belt-connected powered conveyor structure includes: a non-powered conveyor module for supporting and conveying products; a powered conveyor module for supporting and actively conveying products; a power connection mechanism disposed on the powered conveyor module; and a pushing mechanism for pushing the powered conveyor module closer to the non-powered conveyor module. The pushing mechanism can push the powered conveyor module until the power connection mechanism contacts and connects with the non-powered conveyor module to connect power, thereby driving the non-powered conveyor module and the powered conveyor module to synchronously convey products.

[0005] By adopting the above technical solution, during feeding, the product is placed on the powered belt conveyor module, which then transports the product forward. Simultaneously, a pushing mechanism drives the powered belt conveyor module to a power connection mechanism, which connects with the unpowered belt conveyor module to enable power transmission and synchronously transport the product. During unloading, the motor reverses to transport the product from the unpowered belt conveyor module back to the powered belt conveyor module for removal. In other words, a single power source connects two belt conveyors simultaneously, enabling product transport in confined spaces, saving space, simplifying the structure, reducing costs, and facilitating maintenance.

[0006] Preferably, the powered belt conveyor module has first fixed synchronous pulleys on both sides near the end of the unpowered belt conveyor module, and the unpowered belt conveyor module has second fixed synchronous pulleys on both sides near the end of the powered belt conveyor module. The power connection mechanism includes: a power connection mounting plate, with two power connection mounting plates opposite each other on both sides of the powered belt conveyor module; a synchronous pulley set, which is rotatably mounted on the power connection mounting plate; and a double-toothed synchronous belt, which is sleeved on the synchronous pulley set. The two first fixed synchronous pulleys respectively mesh with the two double-toothed synchronous belts. The pushing mechanism can push the powered belt conveyor module until the two double-toothed synchronous belts mesh with the corresponding second fixed synchronous pulleys to connect the power.

[0007] By adopting the above technical solution, during feeding, the pushing mechanism pushes the powered belt conveyor module until the two double-sided toothed synchronous belts mesh with the corresponding second fixed synchronous pulleys. The synchronous pulley set tensions and connects the double-sided toothed synchronous belts into a closed path to connect the power. When the powered belt conveyor module transports products, it drives the first fixed synchronous pulley to rotate, and through the cooperation of the double-sided toothed synchronous belt and the synchronous pulley set, it drives the second fixed synchronous pulley to rotate. The rotation of the second fixed synchronous pulley can drive the belt on the unpowered belt conveyor module to rotate synchronously to transport products. Compared with the traditional power connection using gear / rack structure or magnetic wheel structure, which has shortcomings such as wear / abnormal noise / large impact when connecting power with gear / rack structure, and shortcomings such as slippage / low power transmission of magnetic wheel connection structure, this application achieves power connection by having the double-sided toothed synchronous belt mesh with the first and second fixed synchronous pulleys on both sides respectively. Furthermore, by pushing the powered belt conveyor module closer to / away from the unpowered belt conveyor module through the pushing mechanism, power connection or disconnection can be quickly achieved, which is safer, more efficient, and more stable.

[0008] Preferably, the synchronous pulley assembly includes a third and a fourth fixed synchronous pulley rotatably mounted on the power connection mounting plate, and a first and a second movable synchronous pulley movably mounted on the power connection mounting plate in a vertical direction. The power connection mounting plate is provided with a movable guide rail arranged in a vertical direction and two movable sliders movably mounted on the movable guide rail. The first and second movable synchronous pulleys are respectively mounted on the two movable sliders. An elastic element, which is a spring, is provided between the movable sliders and the power connection mounting plate. When the pushing mechanism pushes the power belt module until the two double-toothed synchronous belts mesh with the corresponding second fixed synchronous pulleys, the double-toothed synchronous belts pull the first and second movable synchronous pulleys closer together and compress the elastic element.

[0009] By adopting the above technical solution, when the pushing mechanism pushes the power belt module to the point where the two double-sided toothed synchronous belts mesh with the corresponding second fixed synchronous pulleys, the double-sided toothed synchronous belts pull the first and second movable synchronous pulleys toward each other and compress the elastic element, so that the first and second movable synchronous pulleys provide pressure and tension when they are compressed and unfolded, making their up-and-down movement more linear and uniform.

[0010] Preferably, the power belt conveyor module includes: a first belt conveyor mounting frame; a first gear rotatably mounted on the first belt conveyor mounting frame; a first belt sleeved on and meshing with the first gear; a speed-regulating motor mounted on the first belt conveyor mounting frame; and a first drive shaft drivingly connected to the speed-regulating motor, wherein the first gear and the first fixed synchronous pulley are mounted on the first drive shaft.

[0011] By adopting the above technical solution, the speed-regulating motor drives the first transmission shaft to rotate through the driving gear, driven gear, and transmission belt, which in turn drives the first gear and the first fixed synchronous pulley to rotate synchronously. The rotation of the first gear drives the first belt to rotate and transport the product. At the same time, when the first fixed synchronous pulley rotates synchronously, it drives the second fixed synchronous pulley to rotate synchronously through the cooperation of the pushing mechanism and the power connection mechanism. That is, it uses one power to connect two sets of belt lines at the same time, realizing the transport of products in narrow spaces, saving space, simplifying the structure, reducing costs, and facilitating maintenance.

[0012] Preferably, the power belt conveyor module further includes roller mounting frames disposed on the first belt conveyor mounting frame and located on both sides of the first belt, and a plurality of auxiliary conveying rollers rotatably arranged on the roller mounting frames along the conveying direction.

[0013] By adopting the above technical solution, multiple auxiliary conveying rollers that are rotated and arranged on the roller mounting frame along the conveying direction form double-sided flow bars. The double-sided flow bars assist in supporting the product and distributing its weight and width dimensions, making the product conveying more stable.

[0015] By adopting the above technical solution, the driving component can be driven by a telescopic cylinder or a motor. In use, the driving component drives the powered belt conveyor module to move relative to the driving mounting plate. The driving guide rail and the driving slider are used to support and guide the module, so that the powered belt conveyor module moves stably until the power connection mechanism contacts and connects with the unpowered belt conveyor module.

[0016] Preferably, the push mounting plate is provided with a positioning detection switch, and the powered belt conveyor module is provided with a positioning detection element corresponding to the positioning detection switch. When the push mechanism pushes the powered belt conveyor module to the point where the power connection mechanism contacts and drives the unpowered belt conveyor module, the positioning detection element is opposite to the positioning detection switch and sends a positioning signal.

[0017] By adopting the above technical solution, the start and stop of the power belt conveyor module can be controlled by the position detection switch. After the position signal is triggered, the machine can be stopped, reversed or alarmed in a coordinated manner, which can avoid the equipment from overtravel collision. The positioning is accurate and reliable and the response speed is fast.

[0018] Preferably, the unpowered belt conveyor module includes a second belt conveyor mounting frame and a second belt disposed on the second belt conveyor mounting frame.

[0019] By adopting the above technical solution, a driven gear is rotatably provided on the second belt mounting frame, the second belt is sleeved on the driven gear and meshes with the driven gear, and the second belt is a flat belt, so that the product placement and transmission are stable and reliable.

[0020] Preferably, the powered belt conveyor module is provided with a plurality of first sensors arranged along the conveying direction, and the unpowered belt conveyor module is provided with a plurality of second sensors arranged along the conveying direction.

[0021] By adopting the above technical solution, multiple first sensors and multiple second sensors are responsible for monitoring the different positional states of the product at various locations throughout the entire feeding and discharging process.

[0022] Preferably, the powered belt conveyor module is provided with two oppositely arranged first guide bars, and the unpowered belt conveyor module is provided with two oppositely arranged second guide bars.

[0023] By adopting the above technical solution, the product is guided by the first guide bar and the second guide bar to prevent the product from deviating during the entire feeding and discharging process.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. During feeding, the product is placed on the powered belt conveyor module, which then transports the product forward. Simultaneously, a pushing mechanism drives the powered belt conveyor module to a power connection mechanism, which connects with the unpowered belt conveyor module to enable power transmission. This allows the unpowered belt conveyor module to synchronously transport the product. During unloading, the motor reverses to transport the product from the unpowered belt conveyor module back to the powered belt conveyor module for removal. This system utilizes a single power source to connect two belt conveyors simultaneously, enabling product transport in confined spaces, saving space, simplifying the structure, reducing costs, and facilitating maintenance. 2. This application achieves power connection by having the first and second fixed synchronous pulleys mesh on both sides of the double-sided toothed synchronous belt, and by using a pushing mechanism to move the powered belt module closer to / away from the unpowered belt module, it can quickly achieve power connection or disconnection, which is safer, more efficient and stable.

[0032] The following is in conjunction with the appendix Figures 1 to 5 This application will be described in further detail.

[0033] This application discloses a synchronous belt-connected power belt conveyor structure, such as... Figure 1 As shown, the system includes a non-powered belt conveyor module 1 for supporting and conveying products, a powered belt conveyor module 2 for supporting and actively conveying products, a power connection mechanism 3 disposed on the powered belt conveyor module 2, and a pushing mechanism 4 for pushing the powered belt conveyor module 2 closer to the non-powered belt conveyor module. The pushing mechanism 4 can push the powered belt conveyor module 2 until the power connection mechanism 3 contacts and connects with the non-powered belt conveyor module 1 to connect power, thereby driving the non-powered belt conveyor module 1 and the powered belt conveyor module 2 to synchronously convey products.

[0034] When using the feeding structure of this application, the product is placed on the powered belt conveyor module, which transports the product forward. Simultaneously, a pushing mechanism pushes the powered belt conveyor module to a power connection mechanism, which then connects with the unpowered belt conveyor module to drive the unpowered belt conveyor module to synchronously transport the product. When unloading, the motor reverses to transport the product from the unpowered belt conveyor module back to the powered belt conveyor module for removal. In other words, it uses one power source to connect two belt conveyors simultaneously, enabling product transport in narrow spaces, saving space, simplifying the structure, reducing costs, and facilitating maintenance.

[0035] Furthermore, such as Figure 3As shown, the powered belt conveyor module 2 has first fixed synchronous pulleys 5 on both sides near the end of the unpowered belt conveyor module 1, and the unpowered belt conveyor module 1 has second fixed synchronous pulleys 6 on both sides near the end of the powered belt conveyor module 2. The power connection mechanism 3 includes a power connection mounting plate 31, a synchronous pulley set 32 ​​rotatably mounted on the power connection mounting plate 31, and a double-tooth synchronous belt 33 sleeved on the synchronous pulley set 32. The two power connection mounting plates 31 are positioned opposite each other on both sides of the powered belt conveyor module 2. The two first fixed synchronous pulleys 5 respectively mesh with the two double-tooth synchronous belts 33. The pushing mechanism 4 can push the powered belt conveyor module 2 until the two double-tooth synchronous belts 33 mesh with the corresponding second fixed synchronous pulleys 6 to connect the power.

[0036] When feeding using the structure of this application, the pushing mechanism pushes the powered belt conveyor module until the two double-sided toothed synchronous belts mesh with the corresponding second fixed synchronous pulleys. The double-sided toothed synchronous belts are then tensioned and connected into a closed path through the synchronous pulley set to connect the power. When the powered belt conveyor module transports products, it drives the first fixed synchronous pulley to rotate, and through the cooperation of the double-sided toothed synchronous belt and the synchronous pulley set, it drives the second fixed synchronous pulley to rotate. The rotation of the second fixed synchronous pulley can drive the belt on the unpowered belt conveyor module to rotate synchronously to transport products. Compared with the traditional power connection using gear / rack structure or magnetic wheel structure, which has shortcomings such as wear / abnormal noise / large impact when connecting power with gear / rack structure, and slippage / low power transmission structure, this application achieves power connection by having the double-sided toothed synchronous belt mesh with the first and second fixed synchronous pulleys on both sides respectively. Furthermore, by pushing the powered belt conveyor module closer to / away from the unpowered belt conveyor module through the pushing mechanism, power connection or disconnection can be quickly achieved, which is safer, more efficient, and more stable.

[0037] Furthermore, such as Figure 2As shown, the synchronous pulley assembly 32 includes a third fixed synchronous pulley 321 and a fourth fixed synchronous pulley 322 rotatably mounted on the power connection mounting plate 31, and a first movable synchronous pulley 323 and a second movable synchronous pulley 324 movably mounted on the power connection mounting plate 31 in the vertical direction. The power connection mounting plate 31 is provided with a movable linear rail 71 arranged in the vertical direction and two movable sliders 72 movably mounted on the movable linear rail 71. The first movable synchronous pulley 323 and the second movable synchronous pulley 324 are respectively mounted on the two movable sliders 72. An elastic element 73 is provided between the movable slider 72 and the power connection mounting plate 31. When the pushing mechanism 4 pushes the power belt module 2 until the two double-tooth synchronous belts 33 mesh with the corresponding second fixed synchronous pulleys 6, the double-tooth synchronous belts 33 pull the first movable synchronous pulley 323 and the second movable synchronous pulley 324 to move closer to each other and compress the elastic element 73. When the pushing mechanism pushes the power belt module to the point where the two double-toothed synchronous belts mesh with the corresponding second fixed synchronous pulleys, the double-toothed synchronous belts pull the first and second movable synchronous pulleys closer together and compress the elastic element, so that the first and second movable synchronous pulleys provide pressure and tension when they are compressed and unfolded, making their up-and-down movement more linear and uniform.

[0038] Furthermore, such as Figure 3 As shown, the powered conveyor belt module 2 includes a first conveyor belt mounting frame 21, a first gear 22 rotatably mounted on the first conveyor belt mounting frame 21, a first belt 23 sleeved on and meshing with the first gear 22, a speed-regulating motor 24 mounted on the first conveyor belt mounting frame 21, and a first transmission shaft 25 connected to the speed-regulating motor 24. The first gear 22 and the first fixed synchronous pulley 5 are mounted on the first transmission shaft 25. The speed-regulating motor drives the first transmission shaft to rotate through the driving gear, driven gear, and transmission belt, which in turn drives the first gear and the first fixed synchronous pulley to rotate synchronously. The rotation of the first gear drives the first belt to rotate and transport the product. At the same time, when the first fixed synchronous pulley rotates synchronously, it drives the second fixed synchronous pulley to rotate synchronously through the cooperation of the pushing mechanism and the power connection mechanism. That is, it uses one power to connect two sets of conveyor belts at the same time, realizing the transport of products in narrow spaces, saving space, simplifying the structure, reducing costs, and facilitating maintenance.

[0039] Furthermore, the powered conveyor belt module 2 also includes roller mounting frames 26 mounted on the first conveyor belt mounting frame 21 and located on both sides of the first belt 23, and multiple auxiliary conveying rollers 27 rotatably arranged on the roller mounting frames 26 along the conveying direction. The multiple auxiliary conveying rollers rotatably arranged on the roller mounting frames along the conveying direction form double-sided flow rails, which assist in supporting the product and distributing its weight and width dimensions, making the product conveying more stable.

[0040] Furthermore, such as Figure 4 As shown, the pushing mechanism 4 includes a pushing mounting plate 41, a pushing guide rail 42 disposed on the pushing mounting plate 41 along the conveying direction, a pushing slider 43 movably disposed on the pushing guide rail 42 and connected to the powered belt conveyor module 2, and a pushing drive member 44 disposed on the pushing mounting plate 41. The driving end of the pushing drive member 44 is connected to the powered belt conveyor module 2 and is used to drive the powered belt conveyor module 2 to move in a direction closer to or away from the unpowered belt conveyor module 1. The pushing drive member can be driven by a telescopic cylinder or a motor. In use, the pushing drive member drives the powered belt conveyor module to move relative to the pushing mounting plate, and the pushing guide rail and the pushing slider cooperate to achieve support and guidance, so that the powered belt conveyor module moves stably until the power connection mechanism contacts and connects with the unpowered belt conveyor module.

[0041] Furthermore, the push mounting plate 41 is equipped with a positioning detection switch 81, and the powered belt conveyor module 2 is equipped with a positioning detection element 82 corresponding to the positioning detection switch 81. When the push mechanism 4 pushes the powered belt conveyor module 2 to the point where the power connection mechanism 3 contacts and drives the unpowered belt conveyor module 1, the positioning detection element 82 aligns with the positioning detection switch 81 and sends a positioning signal. The positioning detection switch controls the start and stop of the powered belt conveyor module. After triggering the positioning signal, it can trigger a shutdown, reversal, or alarm, avoiding equipment overtravel collisions. The positioning is accurate and reliable, and the response speed is fast.

[0042] Furthermore, such as Figure 5 As shown, the unpowered belt conveyor module 1 includes a second belt conveyor mounting frame 11 and a second belt 12 mounted on the second belt conveyor mounting frame 11. A driven gear is rotatably mounted on the second belt conveyor mounting frame, and the second belt is sleeved on the driven gear and meshes with the driven gear. The second belt is a flat belt, which makes the product placement and transmission smooth and reliable.

[0043] Furthermore, the powered conveyor belt module 2 is equipped with multiple first sensors 9 arranged along the conveying direction, and the unpowered conveyor belt module 1 is equipped with multiple second sensors 10 arranged along the conveying direction. The multiple first sensors and multiple second sensors are responsible for monitoring the different positional states of the product at various locations throughout the entire feeding and discharging process.

[0044] Furthermore, the powered conveyor belt module 2 is provided with two opposing first guide bars 13, and the unpowered conveyor belt module 1 is provided with two opposing second guide bars 14. The first and second guide bars guide the product and prevent it from deviating during the entire feeding and discharging process.

[0045] The implementation principle of a synchronous belt-connected power belt conveyor structure according to an embodiment of this application is as follows: During feeding, the product is placed on the powered belt conveyor module, which then transports the product forward. Simultaneously, a pushing mechanism pushes the powered belt conveyor module until the two double-toothed synchronous belts mesh with the corresponding second fixed synchronous pulleys. The synchronous pulley set tensions and connects the double-toothed synchronous belts into a closed path to connect the power supply. When the powered belt conveyor module transports the product, it drives the first fixed synchronous pulley to rotate, which in turn drives the second fixed synchronous pulley to rotate through the cooperation of the double-toothed synchronous belt and the synchronous pulley set. The rotation of the second fixed synchronous pulley drives the belt on the unpowered belt conveyor module to rotate. The system synchronously conveys products, and during material removal, the motor reverses to transfer products from the unpowered belt conveyor module back to the powered belt conveyor module for removal. This means that one power source simultaneously connects two belt conveyors, enabling product transport in confined spaces, saving space, simplifying the structure, reducing costs, and facilitating maintenance. Furthermore, the double-sided toothed synchronous belt pulls the first and second movable synchronous pulleys towards each other, compressing the elastic element. This provides pressure and tension during the compression and unfolding of the first and second movable synchronous pulleys, resulting in more linear and uniform vertical movement.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
