Description

Technical Field

[0001] This invention belongs to the field of circuit board manufacturing, and particularly relates to unlocking devices and circuit board production lines. Background Technology

[0002] In modern manufacturing, particularly in areas involving automated assembly, material handling, and warehousing logistics, carriers are widely used to carry, position, and secure materials of various shapes, such as circuit boards, facilitating their movement and processing between different workstations on the production line. These carriers are typically designed with reliable locking mechanisms to ensure the materials remain stable during transport and processing, preventing displacement, drops, or damage. The carrier structure usually includes a base serving as a fundamental support platform and fastening components slidably mounted on the base, such as locking sliders, claws, or pressure blocks. These fastening components are often designed with specific structures, such as hooks, flanges, or beveled mating parts, to engage with corresponding structures on the material, thus firmly securing the material to the carrier's base. When materials need to be removed from the carrier for subsequent processing, assembly, inspection, or warehousing, a crucial unlocking step is required.

[0003] In many existing production lines, it is necessary to load the carrier onto a fixed support structure and then unlock it via an unlocking structure. However, since the fixed support structure is usually stationary, and in order to ensure that the unlocking structure can function effectively, the physical distance between the fixed support structure and the unlocking structure is designed to be small. This results in a very narrow physical space around the fixed support structure for loading operations, which increases the difficulty of loading the carrier and reduces the efficiency of unlocking. Summary of the Invention

[0004] The purpose of this application is to provide an unlocking device and a circuit board production line, aiming to solve the problems of how to improve the convenience of loading the unlocking device and improve the unlocking efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, an unlocking device is provided for releasing a carrier from fixing a material. The carrier includes a first component for supporting the material and a second component slidably disposed on the first component. The second component is fastened to the material to detachably connect the material. The unlocking device has an unlocking station and a loading station. The unlocking device includes a conveying structure and a pushing structure slidably disposed on the unlocking station. The conveying structure carries the first component at the loading station and drives the first component to slide to the unlocking station. The pushing structure slides to abut against the second component and pushes the second component to slide a predetermined distance along a first direction to release the fastening state between the second component and the material.

[0007] In some embodiments, the unlocking device further includes a drive structure located on the material conveying path, the push structure being connected to the output end of the drive structure, and the drive structure being used to drive the push structure to slide.

[0008] In some embodiments, the driving structure includes a driving member and a rotatably disposed synchronous belt. The driving member is used to drive the synchronous belt to rotate. The pushing structure is connected to one side of the synchronous belt so that the synchronous belt drives the pushing structure to slide along the first direction.

[0009] In some embodiments, two second components are spaced apart along the first direction, and the two second components are respectively located on both sides of the material. Two pushing structures are spaced apart, and each pushing structure corresponds to each of the second components. The synchronous belt connects the two pushing structures to its two sides along the second direction, so that the synchronous belt drives the two pushing structures to move in opposite directions or towards each other. The second direction is set at an angle to the first direction.

[0010] In some embodiments, the drive structure further includes a support seat located on the material conveying path, the drive member and the timing belt are both disposed on the support seat, the support seat is further provided with a guide structure, the pushing structure is connected to the guide structure, and the guide structure is used to guide the pushing structure to move along the first direction.

[0011] In some embodiments, the drive structure further includes a connector that is clamped to the timing belt and the push structure is fixedly connected to the connector.

[0012] In some embodiments, the unlocking device further includes a lifting structure for lifting the first component, the conveying structure having a conveying surface for supporting the first component, the conveying surface having a clearance channel for the lifting structure to pass through, the lifting structure being slidably disposed in the clearance channel, the lifting structure being capable of rising and falling in a third direction, the lifting structure lifting the first component to disengage from the conveying surface during its rising stroke, and the pushing structure pushing the second component when the first component disengages from the conveying surface.

[0013] In some embodiments, the conveying structure includes a first conveyor line and a second conveyor line spaced apart from the first conveyor line along a second direction. The extension direction of the first conveyor line is parallel to the extension direction of the second conveyor line, the second direction is at an angle to the first direction, and the avoidance channel is formed between the first conveyor line and the second conveyor line.

[0014] In some embodiments, the pushing structure includes a connecting rod connected to the output end of the driving structure, a cylinder connected to the connecting rod, and a piston rod extending in a vertical direction. The cylinder and the piston rod are located above the first member, and the piston rod is extended and retracted relative to the cylinder in a vertical direction so that the peripheral wall of the piston rod abuts against the side wall of the second member.

[0015] Secondly, a circuit board production line is provided, which includes the unlocking device described above.

[0016] The beneficial effects of this application are as follows: When in use, the unlocking device of this application carries the first component at the loading station and drives it to slide to the unlocking station through the conveying structure, which replaces the manual handling operation, shortens the transfer time of the carrier between stations, eliminates the waiting and delay caused by manual intervention, and enables the unlocking operation to be seamlessly connected to the automated production line, significantly improving the overall unlocking efficiency; In addition, the conveying structure can drive the first component to slide between the unlocking station and the loading station. At the loading station, the conveying structure can receive the first component. At this time, the pushing structure and its working area on the unlocking station are spatially separated from the loading station. Therefore, the loading of the first component at the loading station is not restricted by the pushing structure and its surrounding compact layout on the unlocking station, providing sufficient and unobstructed physical space for placing the first component, which is conducive to improving the convenience of loading the unlocking device.

[0028] Please see Figures 1 to 4 This application provides an unlocking device for releasing a carrier 200 from fixing a material. The carrier 200 includes a first component 210 for supporting the material and a second component 220 slidably disposed on the first component 210. The second component 220 is fastened to the material for detachable connection. The unlocking device has an unlocking station 400 and a loading station 300. The unlocking device includes a conveying structure 10 and a pushing structure 20 slidably disposed on the unlocking station 400. The conveying structure 10 carries the first component 210 at the loading station 300 and drives the first component 210 to slide to the unlocking station 400. The pushing structure 20 slides to abut against the second component 220 and pushes the second component 220 to slide a predetermined distance along a first direction a to release the fastening state between the second component 220 and the material.

[0029] It should be noted that the material provided in this embodiment can be a circuit board, and the carrier 200 is used to load and fix the circuit board. When electronic components need to be assembled on the circuit board, the unlocking device can release the carrier 200 from fixing the material, thereby facilitating the assembly of electronic components on the circuit board. Understandably, the first component 210 is a flat structure that can support the material. The second fastener can specifically be a locking slider 342, a claw, or a pressure block, etc. The second component 220 is usually designed with a specific structure, such as a hook, flange, or inclined mating part, which can engage or mesh with the corresponding structure on the material, thereby detachably connecting it to the material. In addition, the top surface of the first component 210 is provided with a groove, and the second component 220 is slidably connected to the groove, thereby allowing the second component 220 to be slidably disposed on the first component 210.

[0030] It should be noted that the push structure 20 pushes the second component 220 to slide a predetermined distance along the first direction a. Optionally, the predetermined distance ranges from 1mm to 15mm, and can be flexibly set according to different materials and carriers 200. Understandably, the predetermined distance cannot be too small, as this would not guarantee the release of the engagement between the second component 220 and the material. Nor can the predetermined distance be too large, as this would cause interference between the second component 220 and other structures on the first component 210.

[0031] In this embodiment, the material after being released from its fixed position can be taken away by downstream equipment of the conveying structure 10, such as a robotic arm. The empty carrier 200 can also be conveyed by the conveying structure 10 to the downstream or recycling position. This significantly reduces the waiting time between equipment, optimizes the production line layout, and improves the overall equipment efficiency.

[0032] In this embodiment, the loading station 300 and the unlocking station 400 are spaced apart along the material conveying direction. At the loading station 300, the conveying structure 10 is in the receiving state. At this time, the pushing structure 20 and its working area on the unlocking station 400 are spatially separated from the loading station 300. Therefore, the loading station 300 has ample space and is unobstructed. The operator or robotic arm only needs to perform a simple "placement" action to complete the loading without the need for precise alignment or careful avoidance. This significantly shortens the time required for a single loading and significantly improves the efficiency of the loading process, thereby speeding up the pace of the entire unlocking process. Furthermore, the spacious loading space greatly reduces the possibility of accidental collisions and effectively protects the carrier 200, the material, and the pushing structure 20 from accidental collision damage.

[0033] When in use, the unlocking device of this application carries the first component 210 at the loading station 300 via the conveying structure 10 and drives it to slide to the unlocking station 400, replacing the manual handling operation, shortening the transfer time of the carrier 200 between stations, eliminating the waiting and delay caused by manual intervention, and enabling the unlocking operation to be seamlessly connected to the automated production line, significantly improving the overall unlocking efficiency; and the conveying structure 10 can drive the first component 210 to slide between the unlocking station 400 and the loading station 300. At the loading station 300, the conveying structure 10 can receive the first component 210. At this time, the pushing structure 20 and its working area on the unlocking station 400 are spatially separated from the loading station 300. Therefore, loading the first component 210 at the loading station 300 is not restricted by the pushing structure 20 and its surrounding compact layout on the unlocking station 400, providing sufficient and unobstructed physical space for placing the first component 210, which is conducive to improving the convenience of loading the unlocking device.

[0034] In addition, during or after the conveying structure 10 transports the carrier 200 to the unlocking station 400, it can ensure that the first component 210, the second component 220 fixed on the first component 210, and the material are accurately and stably positioned in the preset position, providing a reliable basis for subsequent unlocking actions.

[0035] In some embodiments, such as Figure 2 and Figure 3 As shown, the unlocking device also includes a drive structure 30 located on the material conveying path. The pushing structure 20 is connected to the output end of the drive structure 30, and the drive structure 30 is used to drive the pushing structure 20 to slide. By setting the drive structure 30, the operator or automated equipment only needs to place the carrier 200 on the conveying structure 10 of the loading station 300, and the subsequent positioning, conveying, and unlocking actions are all automatically completed by the device. This greatly simplifies the operation steps, reduces the dependence on skilled operators, reduces manpower input, and effectively reduces labor costs and training and management costs.

[0036] Furthermore, by setting the driving structure 30 to drive the sliding of the pushing structure 20, the pushing force of the pushing structure 20 is precisely controllable. The pushing force of the pushing structure 20 is directly applied to the second component 220 that needs to be moved, with a clear direction, avoiding misoperation or force dispersion. Moreover, the sliding stroke of the pushing structure 20 is precise, ensuring that the second component 220 is pushed to the minimum and safe distance required for complete disengagement, reducing the risk of unlocking failure due to insufficient pushing distance or material damage due to excessive pushing, thus improving the reliability of unlocking. Furthermore, by setting the driving structure 30, each unlocking action is executed by the mechanical structure according to a preset program, with highly consistent pushing distance, speed, and force, completely eliminating the uncertainty of manual operation and ensuring the stability of product quality.

[0037] Understandably, the embodiments of this application also include a control system (not shown in the figure). The conveying structure 10, the pushing structure 20, and the driving structure 30 are all communicatively connected to the control system. The control system can control the automatic coordination and operation of the conveying structure 10, the pushing structure 20, and the driving structure 30. The entire process is greatly automated through the automatic coordination and operation of the conveying structure 10, the pushing structure 20, and the driving structure 30, which reduces manual operation and greatly improves blocking efficiency.

[0038] In some embodiments, such as Figure 3As shown, the drive structure 30 includes a drive member 31 and a rotatably mounted synchronous belt 32. The drive member 31 drives the synchronous belt 32 to rotate. The pushing structure 20 is connected to one side of the synchronous belt 32 so that the synchronous belt 32 drives the pushing structure 20 to slide along the first direction a. By setting the synchronous belt 32, the drive member 31 can be prevented from being directly connected to the pushing structure 20, thus preventing the drive member 31 from stalling or losing its synchronization due to load fluctuations (such as sudden changes in resistance) on the pushing structure 20. The synchronous belt 32 can buffer impacts and maintain the straightness of the motion trajectory, preventing the pushing structure 20 from deviating or getting stuck. In addition, by setting the synchronous belt 32, the friction noise of the synchronous belt 32 is significantly reduced during operation, and the synchronous belt 32 can bypass the complex structure inside the unlocking device, such as the wiring harness, etc., and achieve multi-angle steering through the synchronous belt 32 wheel, adapting to narrow or irregular spaces and avoiding restrictions on the installation position of the drive structure 30.

[0039] Optionally, the drive unit 31 and the timing belt 32 can be packaged as independent modules to facilitate adaptation to different materials. Only the length of the timing belt 32 needs to be adjusted, without redesigning the drive unit 31. Of course, the timing belt 32 can also be used as an independent component, which can be replaced separately when damaged without disassembling the entire drive structure 30, thereby helping to reduce maintenance costs and improve the convenience of maintenance and adjustment.

[0040] Optionally, such as Figure 3 As shown, the driving component 31 includes a driving wheel 311, a driven wheel 312, and a rotary driver 313 for driving the driving wheel 311 to rotate. The driving wheel 311 and the driven wheel 312 are arranged at intervals along a first direction a. The two ends of the timing belt 32 are respectively wound around the driving wheel 311 and the driven wheel 312. The rotary driver 313 can specifically be a drive motor. In other possible embodiments, the rotary driver 313 can be a roller motor, and the two ends of the timing belt 32 are directly sleeved on the two ends of the roller motor.

[0041] In some embodiments, two second components 220 are spaced apart along the first direction a, and two push structures 20 are spaced apart on both sides of the material. Each push structure 20 corresponds to a second component 220. The synchronous belt 32 connects the two push structures 20 on both sides along the second direction b, so that the synchronous belt 32 drives the two push structures 20 to move in opposite directions or towards each other. The second direction b is at an angle to the first direction a. Understandably, the two push structures 20 correspond to the two second components 220, and both second components 220 are engaged with the material and jointly clamp the material, improving the stability of the material fixation. When unlocking is required, the synchronous belt 32 drives the two push structures 20 to slide in opposite directions, thereby releasing the clamping and fixing of the material. Understandably, when it is necessary to re-fix the material, the synchronous belt 32 drives the two pushing structures 20 to move towards each other, thereby driving the two second components 220 to move towards each other, so as to clamp the material between the two second components 220.

[0042] It is understood that the plane defined by the rotation trajectory of the synchronous belt 32 is a horizontal plane. The line connecting the driving pulley 311 and the driven pulley 312 divides the synchronous belt 32 into a first connecting segment 321 and a second connecting segment 322. The first connecting segment 321 and the second connecting segment 322 are spaced apart along the second direction b. One abutting structure 20 connects to the first connecting segment 321, and the other abutting structure 20 connects to the second connecting segment 322. When the synchronous belt 32 rotates, the first connecting segment 321 and the second connecting segment 322 move in opposite directions, thereby driving the two abutting structures 20 to slide in opposite directions or move towards each other. Optionally, the first direction a is perpendicular to the second direction b.

[0043] Of course, in other possible implementations, the timing belt 32 can also be replaced by a chain, and the drive unit 31 can drive the sprocket to rotate, thereby driving the chain to move, and the pushing structure 20 moves synchronously with the chain. The chain has high tensile strength, strong impact resistance and corrosion resistance, and the chain can be adapted to different sizes of carriers 200 and materials by adding or removing chain links, which provides high design flexibility.

[0044] In some embodiments, the drive structure 30 further includes a support base 33 located on the material conveying path. The drive member 31 and the timing belt 32 are both disposed on the support base 33. The support base 33 also includes a guide structure 34. The pushing structure 20 is connected to the guide structure 34, which guides the pushing structure to move along the first direction a. By providing the guide structure 34, the sliding of the pushing structure 20 becomes more stable and reliable, and deviation of the pushing structure 20 during sliding can be effectively avoided. The guide structure 34 includes a guide rail 341 connected to the support base 33 and extending along the first direction a, and a slider 342 slidably connected to the guide rail 341. The pushing structure 20 is connected to the slider 342, thereby achieving a sliding connection between the pushing structure 20 and the guide rail 341.

[0045] Optionally, the guide rail 341 is disposed within the space formed by the synchronous belt 32, thereby making full use of the space inside the synchronous belt 32 and avoiding the guide rail 341 and slider 342 occupying excess space, which is conducive to miniaturization of the unlocking device. In addition, when multiple pushing structures 20 are provided, multiple sliders 342 can be provided accordingly, with each slider 342 connected to each pushing structure 20 in a one-to-one manner, and each slider 342 slidably connected to the same guide rail 341, which is conducive to further reducing the space occupied by the drive structure 30 and miniaturizing the unlocking device.

[0046] In some embodiments, such as Figure 3 As shown, the drive structure 30 also includes a connector 35, which is clamped to the timing belt 32 and fixedly connected to the pushing structure 20. By providing the connector 35, the timing belt 32 is prevented from being directly fixed to the pushing structure 20, thus avoiding breakage of the timing belt 32 due to uneven distribution of driving force. The connector 35 acts as a rigid intermediary, evenly transmitting the tension of the timing belt 32 to the pushing structure 20, preventing deformation of the flexible belt due to uneven stress. Furthermore, the connector 35 can be replaced individually when damaged, without disassembling the entire drive structure 30, enabling quick replacement and improving maintenance convenience.

[0047] In some embodiments, to improve the stability of the connection between the connector 35 and the timing belt 32, a row of grooves is provided on the side of the connector 35 that is in contact with the timing belt 32, thereby increasing the grip and providing an anti-slip effect. Optionally, the connector 35 is made of an elastic material, such as rubber, sponge, or silicone. When external impacts such as bumps or resistance occur, the connector 35 can absorb the instantaneous impact force, preventing the timing belt 32 from being subjected to sudden load changes and breaking.

[0048] In some embodiments, such as Figure 1 and Figure 4As shown, the unlocking device also includes a lifting structure 40 for lifting the first component 210. The conveying structure 10 has a conveying surface 500 for supporting the first component 210. The conveying surface 500 is provided with a clearance channel 600 for the lifting structure 40 to pass through. The lifting structure 40 is slidably disposed in the clearance channel 600. The lifting structure 40 can rise and fall along a third direction c. During its rising stroke, the lifting structure 40 lifts the first component 210 until it is separated from the conveying surface 500. When the first component 210 is separated from the conveying surface 500, the pushing structure 20 pushes the second component 220, thereby making the position of the first component 210 more stable when the pushing structure 20 pushes the second component 220, thus improving the reliability of unlocking. Understandably, when the fixed state of the material is released, the lifting structure 40 descends, causing the first component 210 to fall back onto the conveying surface 500. The material and carrier 200 can then be conveyed by the conveying structure 10 to the downstream equipment.

[0049] In some embodiments, the conveying structure 10 includes a first conveying line 11 and a second conveying line 12 spaced apart from the first conveying line 11 along a second direction b. The extension direction of the first conveying line 11 is parallel to the extension direction of the second conveying line 12, and the second direction b is at an angle to the first direction a. A clearance channel 600 is formed between the first conveying line 11 and the second conveying line 12. Since the lifting structure 40 is located between the first conveying line 11 and the second conveying line 12, the lifting structure 40 can rotate within the conveying surface 500 of the conveying structure 10 without occupying the side space of the conveying structure 10, thereby making reasonable use of space and reducing the overall size of the unlocking device.

[0050] Specifically, in the embodiments of this application, both the first conveyor line 11 and the second conveyor line 12 can be belt transmission structures. Due to tension, the belt transmission structure generates a clamping force at the contact part between the belt and the pulley. When the main pulley is running, it drives the belt by friction. Because belt transmission works by friction, it can effectively mitigate the impact of the load, and the operation is smooth and noiseless.

[0051] Optionally, such as Figure 4 As shown, the lifting structure 40 includes a fixed plate 41 located below the conveying surface 500, a lifting driver 42 connected to the fixed plate 41, and a lifting plate 43 connected to the output end of the lifting driver 42. The lifting plate 43 is used to support the first component 210. The lifting driver 42 drives the lifting plate 43 to rise and fall, thereby driving the first component 210 to rise and fall. Optionally, the fixed plate 41 is provided with a plurality of guide sleeves 45 around its periphery, and the bottom of the lifting plate 43 is connected with a plurality of guide posts 44. Each guide post 44 corresponds to each guide sleeve 45 and passes through each guide sleeve 45. Through the cooperation of the guide posts 44 and the guide sleeves 45, the lifting of the lifting plate 43 can be guided, preventing the lifting trajectory of the lifting plate 43 from deviating.

[0052] In some embodiments, the pushing structure 20 includes a connecting rod 21 connected to the output end of the drive structure 30, a cylinder 22 connected to the connecting rod 21, and a piston rod 23 extending in a vertical direction. The cylinder 22 and piston rod 23 are located above the first member 210. The piston rod 23 is telescopically arranged relative to the cylinder 22 in a vertical direction so that the peripheral wall of the piston rod 23 abuts against the side wall of the second member 220. Understandably, the cylinder 22 and piston rod 23 are located above the first member 210. Because the piston rod 23 telescopically extends relative to the cylinder 22 in a vertical direction, the length of the piston rod 23 can be extended, ensuring that the peripheral wall of the piston rod 23 can contact the side wall of the second member 220, ensuring that the pushing structure 20 can push the second member 220 to move, thereby improving the reliability of the unlocking action.

[0053] Understandably, when two pushing structures 20 are provided, the extension directions of the two connecting rods 21 of the two pushing structures 20 are both parallel to the second direction b. In addition, multiple second components 220 can be provided at intervals along the second direction b to enhance the fixing effect on the material. At this time, multiple cylinder bodies 22 and piston rods 23 can be arranged at intervals on the same connecting rod 21, and each cylinder body 22 and piston rod 23 corresponds to each second component 220.

[0054] The present invention also proposes a circuit board production line, which includes an unlocking device. The specific structure of the unlocking device is as described in the above embodiments. Since the circuit board production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0055] In summary, when the unlocking device of this application is in use, the conveying structure 10 carries the first component 210 at the loading station 300 and drives it to slide to the unlocking station 400, replacing the manual handling operation, shortening the transfer time of the carrier 200 between stations, eliminating the waiting and delay caused by manual intervention, and enabling the unlocking operation to be seamlessly connected to the automated production line, significantly improving the overall unlocking efficiency. Furthermore, the conveying structure 10 can drive the first component 210 to slide between the unlocking station 400 and the loading station 300. At the loading station 300, the conveying structure 10 can receive the first component 210. At this time, the pushing structure 20 and its working area on the unlocking station 400 are spatially separated from the loading station 300. Therefore, loading the first component 210 at the loading station 300 is not restricted by the pushing structure 20 and its surrounding compact layout on the unlocking station 400, providing sufficient and unobstructed physical space for placing the first component 210, which is conducive to improving the convenience of loading the unlocking device.

[0056] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
