Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board stencil storage technology, and more specifically, it relates to a circuit board stencil storage device. Background Technology
[0002] In existing technologies, PCB stencil storage devices are indispensable equipment in various electronic manufacturing projects, including modern electronics manufacturing, printed circuit board production lines, surface mount technology processes, and automated electronic assembly. They are widely used in key operational stages such as stencil classification, orderly management, and rapid retrieval in PCB manufacturing enterprises, electronic product production workshops, and various electronic assembly lines. To meet the storage needs of PCB stencils of different specifications and improve the adaptability of equipment to diverse production tasks, existing technologies typically use storage racks with storage slots for stencil storage. These racks are designed with storage slot structures of different spacing, depth, and width according to different PCB sizes, stencil thicknesses, and production process requirements to ensure that PCB stencils of various specifications receive appropriate storage space and stable support and protection. However, in actual electronic manufacturing processes, due to factors such as frequent product updates, diversified order types, and high production task switching frequencies, production lines often need to handle PCB stencils of different sizes and thicknesses. This necessitates that the stencil storage device possesses… While offering a degree of flexibility, existing storage devices generally suffer from fundamental drawbacks when it comes to replacing storage racks with those featuring slots of varying spacing, depth, or width. These rack replacement mechanisms require screwdrivers, wrenches, and specialized tools to accurately disassemble and reinstall the racks. This high reliance on specialized tools severely limits the equipment's rapid adjustment capabilities and the production line's flexible switching efficiency. This is particularly problematic in emergency situations involving fast-paced electronic manufacturing production requiring rapid line changes, immediate adjustments to product specifications, urgent equipment maintenance, or rapid production scheduling. Traditional tool-dependent replacement designs often fail to meet the demands of rapid operation, leading to prolonged downtime, significantly reduced production efficiency, increased manufacturing costs, and delayed delivery. Ultimately, this severely restricts the on-site usability of circuit board stencil storage devices and the continuous operation efficiency of electronic manufacturing production lines.
[0003] Secondly, some technologically improved circuit board stencil storage devices have successfully achieved convenient rack replacement to a certain extent, allowing for quick disassembly and installation without the need for specialized tools. However, these improved storage devices, primarily designed for ease of operation, often overemphasize the simplification and convenience of replacement operations during the development process, resulting in design deficiencies and technical defects in the overall stability and reliability of the fixed connection structure. Specifically, in the actual use environment of circuit board stencil storage devices, the rack fixing structure needs to withstand a combination of complex load factors, including the rack's own weight, the weight of multiple layers of stencils, inertial forces and impact loads during equipment movement and transportation, vibrations generated during internal handling operations, lateral impacts from accidental collisions, and alternating loads from repeated stencil handling during daily use. Under the long-term continuous action of these harsh working conditions, the overly simple quick-release connection mechanism is extremely susceptible to the cumulative effects of various adverse factors such as static loads caused by the weight of the steel mesh, dynamic impact loads caused by equipment movement, and repeated stresses generated by the picking and placing operations. This can gradually lead to serious structural failures such as loosening of fixed components, increased connection gaps, and even complete detachment of the fixed structure. When the fixed structure of the storage rack becomes loose due to external forces and equipment movement, it will not only cause the storage rack to shift position and the steel mesh to become unstable, affecting the accuracy and efficiency of steel mesh retrieval, but may also cause a chain of problems such as steel mesh slippage, storage chaos, and operational difficulties. When the fixed structure accidentally detaches and completely fails, the storage rack may instantly lose its support and positioning, causing serious safety accidents such as steel mesh scattering, equipment damage, and personal injury, resulting in damage to expensive circuit board steel mesh, production interruption, and economic losses.

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides a circuit board stencil storage device, which has the following advantages:
[0017] 1. By setting up a tool-free adjustment mechanism consisting of a separating sleeve, a push block, a transmission sleeve, a matching block, a spring, an abutment block, and a connector frame, the technical problem of traditional circuit board stencil storage devices requiring screwdrivers, wrenches, and special disassembly tools for accurate disassembly and reinstallation when changing storage racks is effectively solved. When changing storage racks, the operator only needs to rotate the separating sleeve forward, which drives the push block to rotate forward. Due to the inclined structure design of the push block and the matching block, the spring returns to its original position, pushing the transmission sleeve to slide. The transmission sleeve drives the matching block to move so that it is always in close contact with the push block. The abutment groove on the inner side of the transmission sleeve no longer limits the outer wall of the abutment block. The abutment spring returns to its original position, pushing the abutment block and moving the connector frame outward. The device moves and slides out of the insertion slot, thus enabling rapid separation of the implant sleeve and implant rod. The entire process requires no professional tools and can be completed simply by manual rotation. This significantly improves the ease of equipment replacement and the flexible switching efficiency of electronic manufacturing production lines. Especially in emergency situations where the pace of electronic manufacturing production is fast and requires rapid line changes, product specifications change and require immediate adjustment, equipment maintenance requires urgent handling, or production tasks require rapid adaptation, it can meet the needs of rapid operation, effectively shorten production downtime, improve production efficiency, and avoid adverse consequences such as increased manufacturing costs and delayed delivery. It greatly improves the on-site usability of the circuit board stencil storage device and the continuous operation efficiency of the electronic manufacturing production line.
[0018] 2. By setting up a multi-locking and stabilizing mechanism composed of components such as an action plate, action groove, action hole, locking sleeve, bearing rod, bearing plate, bearing spring, fixed clamp, fixed clamp rod, fixed clamp plate, fixed clamp groove, and drag spring, the technical defects of the fixed connection structure of the improved circuit board stencil storage device, such as poor stability and easy loosening or even complete detachment of the fixed structure due to external forces and equipment movement, are effectively solved. After the storage rack is installed, the inner wall of the abutment groove gradually presses the abutment block inward, causing the plug-in frame to re-lock into the plug-in groove to form a stable locking relationship. The drag spring resets and pulls the fixed clamp plate to re-insert the fixed clamp rod into the original fixed clamp groove. Rotating the action plate in the forward direction resets the bearing spring and pushes the locking sleeve to slide reset. Then, rotating the action plate in the reverse direction causes the action hole and action groove to rotate and reset to a position that does not correspond to the bearing plate and bearing rod. When the bearing rod cooperates with the bearing plate to support and limit the locking sleeve, the inner wall of the locking sleeve re-limits the outer wall of the fixed clamp plate. The clamping rod and clamping groove work together to limit the rotation of the clamping frame and prevent the separation sleeve from rotating accidentally. This multi-locking mechanism can effectively resist the combined effects of various complex load factors, such as the self-weight of the storage rack, the weight of multiple layers of steel mesh, the inertial force and impact load during equipment movement and transportation, the vibration force generated by handling operations inside the workshop, the lateral impact force generated by accidental collisions, and the alternating load generated by repeated picking and putting away of steel mesh during daily use. Even under the long-term cumulative effects of adverse factors such as the static load generated by the weight of the steel mesh, the dynamic impact load caused by equipment movement, and the repeated stress generated by picking and putting away operations, the locking components can maintain a stable connection, effectively preventing the fixing components from loosening and the connection gap from increasing. This avoids serious safety accidents such as storage rack position displacement, unstable steel mesh storage, steel mesh slippage, equipment damage, and personal injury caused by the failure of the fixing structure, thus ensuring the safety and reliability of the circuit board steel mesh storage device.

The insert sleeve 3 is connected, and a clamping bracket 13 is fixedly provided on one side of the separating sleeve 5. A clamping rod 14 is slidably provided in the clamping bracket 13. A clamping plate 15 is connected to one end of the clamping rod 14. A locking sleeve 16 is fitted on the outside of the implant sleeve 3. Multiple clamping grooves 17 are opened on the outside of the implant sleeve 3. A bearing rod 18 is fixedly connected to one side of the locking sleeve 16. A bearing plate 19 is fixedly provided on the bearing rod 18. The bearing plate 19 is provided in two places. An abutment groove 20 is opened on the inside of the transmission sleeve 7. An abutment block 21 is movably provided in the abutment groove 20. A plug-in bracket 22 is connected to one side of the abutment block 21. A plug-in groove 23 is opened on the outside of the implant rod 4. One end of the plug-in bracket 22 passes through the implant sleeve 3 and is inserted into the plug-in groove 23. The inner wall of the abutment groove 20 and the outer wall of the abutment block 21 are both designed with a chamfered structure.
[0029] The inner side of the fixing frame 1 is symmetrically provided with storage racks 24, and the implantation rod 4 is fixedly connected to one side of the storage rack 24. Multiple storage slots 25 are opened on one side of the storage rack 24.
[0030] The frame 26 is detachably provided on the outside of the fixed frame 1. A handle 27 is fixedly provided on one side of the frame 26. A caster wheel 28 is detachably provided at the bottom of the frame 26.
[0031] In this embodiment, when the storage rack 24 needs to be replaced, it must first be removed. First, the actuating plate 9 is rotated clockwise. Then, the actuating plate 9 will drive the actuating hole 11 and the actuating groove 10 to rotate clockwise. When the actuating hole 11 rotates to a position concentric with the support plate 19, the locking sleeve 16 is pushed. The locking sleeve 16 will drive the support rod 18 and the support plate 19 on one side to gradually slide into the actuating hole 11. At the same time, the locking sleeve 16 and the actuating plate 9 will cooperate to compress the support spring 30. When the support spring 30 is compressed to its limit, the support plate 19 near the locking sleeve 16 just slides through the actuating hole 11. The device moves to the other side of the action plate 9, and then rotates the action plate 9 in the opposite direction, causing the action plate 9 to drive the action hole 11 and the action groove 10 to rotate in the opposite direction, so that the bearing rod 18 enters the action groove 10. When the outer wall of the bearing rod 18 contacts one end of the inner wall of the action groove 10, the rotation of the action plate 9 stops. At this time, the bearing rod 18, together with the bearing plate 19 near the locking sleeve 16, limits the locking sleeve 16 to one side of the action plate 9, so that the locking sleeve 16 no longer limits the outer wall of the clamping plate 15. Then, the separation sleeve 5 is rotated in the forward direction. The separation sleeve 5 will drive multiple clamping brackets 13 on one side to rotate in the forward direction. Then, the clamping brackets 13 drive the clamping brackets to rotate in the forward direction. Plate 15, clamping rod 14, and drag spring 31 rotate in the forward direction. Then, the inner wall of clamping groove 17 presses against one end of clamping rod 14. Due to the rounded corner design at the edge of clamping rod 14 and inner wall of clamping groove 17, one end of clamping rod 14 gradually slides out of clamping groove 17, and the other end of clamping rod 14 drives clamping plate 15 to slide outward, causing clamping plate 15 to drive drag spring 31 to stretch outward. At the same time, separating sleeve 5 drives outer push block 6 to rotate in the forward direction. Due to the special structural design of push block 6 and matching block 8, when push block 6 rotates in the forward direction, spring spring 12 resets and pushes transmission sleeve 7, causing transmission sleeve 7 to move along... As the guide rail 29 gradually slides, the transmission sleeve 7 will drive the matching block 8 to move, so that one side of the matching block 8 is always in close contact with the push block 6. Then, the inner abutment groove 20 of the transmission sleeve 7 gradually stops limiting the outer wall of the abutment block 21. Then, multiple abutment springs 32 simultaneously reset and push the abutment block 21, so that the abutment block 21 drives one side of the insertion frame 22 to move outward. Then, one end of the insertion frame 22 will gradually slide out of the insertion groove 23. Then, the implantation sleeve 3 is pulled to one side to separate the implantation sleeve 3 and the implantation rod 4. Then, the other implantation sleeves 3 are removed according to the above steps. Then, the storage rack 24 can be removed from the inside of the fixing frame 1.
[0032] Please see Figures 3-5 As a further implementation of the device as a whole: a guide rail 29 is fixedly provided on the outside of the implant sleeve 3, the guide rail 29 is aligned with the abutment block 21, and the guide rail 29 is located in the abutment groove 20.
[0033] A bearing spring 30 is movably sleeved on the outside of the bearing rod 18. One end of the bearing spring 30 is connected to the locking sleeve 16, and the other end of the bearing spring 30 abuts against one side of the actuating plate 9.
[0034] Both the end of the clamping rod 14 and the edge of the inner wall of the clamping groove 17 adopt a rounded corner structure design.
[0035] A drag spring 31 is movably sleeved on the outside of the clamping rod 14, and the two ends of the drag spring 31 are connected to the clamping plate 15 and the clamping frame 13 respectively.
[0036] Multiple abutment springs 32 are connected to one side of the abutment block 21, and the other end of the abutment spring 32 is connected to the outer wall of the implant sleeve 3.
[0037] More specifically, when the removed storage rack 24 has been replaced and needs to be reinstalled, first place the storage rack 24 inside the fixing frame 1, then make one side of the storage rack 24 fit against the inner wall of the side plate 2, and make the implantation rod 4 fixedly connected to one side of the storage rack 24 pass through the reserved hole on the side plate 2. Then, put the implantation sleeve 3 from the outside of the side plate 2 to the outside of the implantation rod 4. Then, rotate the separation sleeve 5 in the opposite direction, so that the separation sleeve 5 drives the fixing rod 14, the fixing plate 15 and the drag spring 31 to rotate in the opposite direction through the fixing bracket 13 on one side. At the same time, the separation sleeve 5 will drive the outer push block 6 to rotate in the opposite direction and reset. Then the push block 6 pushes the matching block 8 to one side, so that the matching block 8 slides and resets. Matching block 8 drives transmission sleeve 7 to slide and reset along guide rail 29, and transmission sleeve 7 drives inner abutment groove 20 to slide and reset. Due to the chamfer design of one side of inner wall of abutment groove 20 and one side of outer wall of abutment block 21, the inner wall of abutment groove 20 gradually presses abutment block 21 inward, causing abutment block 21 to move inward and reset. Abutment block 21 will also compress one side abutment spring 32, causing abutment block 21 to drive one side plug bracket 22 to gradually engage in plug groove 23. At the same time, transmission sleeve 7 will compress spring spring 12. When separation sleeve 5 is fully reset, one end of plug bracket 22 is reinserted into plug groove 23, forming an engagement relationship. At this time, clamping bracket 13 just drives clamping rod 14 and other components to rotate to the original position. The clamping groove 17 is positioned accordingly. Then, the drag spring 31 resets and pulls the clamping plate 15, causing the clamping plate 15 to slide inward along one side of the clamping rod 14. One end of the clamping rod 14 is then reinserted into the original clamping groove 17. The actuating plate 9 is then rotated forward, causing the actuating hole 11 and the actuating groove 10 to rotate forward. When the actuating hole 11 rotates again to a position concentric with the bearing plate 19, the bearing spring 30 resets and pushes the locking sleeve 16, causing the locking sleeve 16 to slide back to its original position. The locking sleeve 16 also causes one side of the bearing rod 18 and the two bearing plates 19 to slide back to their original positions. After the bearing spring 30 is fully reset, the bearing plate 19 at the top of the bearing rod 18 moves back to the original side of the actuating plate 9, and then rotates in the opposite direction. The action plate 9 resets, causing the action hole 11 and action groove 10 to rotate and reset to a position that does not correspond to the support plate 19 and support rod 18. At this time, the support rod 18, together with the top support plate 19, supports the locking sleeve 16 to one side of the action plate 9, making the locking sleeve 16 unable to slide easily. Then, the inner wall of the locking sleeve 16 will re-limit the outer wall of the clamping plate 15, making the clamping plate 15 and clamping rod 14 unable to slide outward. Then, the clamping rod 14 and clamping groove 17 cooperate to form a rotation limit on the clamping frame 13, preventing the separation sleeve 5 from rotating accidentally, thereby achieving convenient and stable installation of the implantation sleeve 3. Then, the other implantation sleeves 3 are locked together according to the above steps, thereby achieving stable fixation of the replacement storage rack 24.
[0038] In summary, during the use or operation of the overall equipment: when it is necessary to replace the storage rack 24, the storage rack 24 must first be removed. First, rotate the actuating plate 9 clockwise. Then, the actuating plate 9 will drive the actuating hole 11 and the actuating groove 10 to rotate clockwise. When the actuating hole 11 rotates to a position concentric with the support plate 19, push the locking sleeve 16. The locking sleeve 16 will drive the support rod 18 and the support plate 19 on one side to gradually slide into the actuating hole 11. At the same time, the locking sleeve 16 and the actuating plate 9 will cooperate to compress the support spring 30. When the support spring 30 is compressed to its limit, the support plate 19 near the locking sleeve 16 will just slide. The rod passes through the actuation hole 11 and moves to the other side of the actuation plate 9. Then, the actuation plate 9 is rotated in the opposite direction, causing the actuation hole 11 and the actuation groove 10 to rotate in the opposite direction. This allows the bearing rod 18 to enter the actuation groove 10. When the outer wall of the bearing rod 18 contacts one end of the inner wall of the actuation groove 10, the rotation of the actuation plate 9 is stopped. At this time, the bearing rod 18, together with a bearing plate 19 near the locking sleeve 16, limits the locking sleeve 16 to one side of the actuation plate 9, so that the locking sleeve 16 no longer limits the outer wall of the clamping plate 15. Then, the separation sleeve 5 is rotated in the forward direction. The separation sleeve 5 will drive multiple clamping brackets 13 on one side to rotate in the forward direction. Then, the clamping brackets 1... 3. The clamping plate 15, clamping rod 14, and dragging spring 31 rotate forward. Then, the inner wall of the clamping groove 17 presses against one end of the clamping rod 14. Due to the rounded corner design at the edge of the clamping rod 14 and the inner wall of the clamping groove 17, one end of the clamping rod 14 gradually slides out of the clamping groove 17, and the other end of the clamping rod 14 drives the clamping plate 15 to slide outward, causing the clamping plate 15 to pull the dragging spring 31 outward. At the same time, the separating sleeve 5 drives the outer push block 6 to rotate forward. Due to the special structural design of the push block 6 and the matching block 8, when the push block 6 rotates forward, the spring spring 12 resets and pushes the transmission sleeve 7, causing the transmission... The sleeve 7 gradually slides along the guide rail 29, and the transmission sleeve 7 drives the matching block 8 to move, so that one side of the matching block 8 is always in close contact with the push block 6. Then, the inner abutment groove 20 of the transmission sleeve 7 gradually stops limiting the outer wall of the abutment block 21. Then, multiple abutment springs 32 synchronously reset and push the abutment block 21, so that the abutment block 21 drives one side of the insertion frame 22 to move outward. Then, one end of the insertion frame 22 will gradually slide out of the insertion groove 23. Then, the implant sleeve 3 is pulled to one side to separate the implant sleeve 3 and the implant rod 4. Then, the other implant sleeves 3 are removed according to the above steps. Then, the storage rack 24 can be removed from the inside of the fixing frame 1.
[0039] When the removed storage rack 24 has been replaced and needs to be reinstalled, first place the storage rack 24 inside the fixed frame 1, then make one side of the storage rack 24 fit against the inner wall of the side plate 2, and make the implantation rod 4 fixedly connected to one side of the storage rack 24 pass through the reserved hole on the side plate 2. Then, put the implantation sleeve 3 from the outside of the side plate 2 to the outside of the implantation rod 4. Then rotate the separation sleeve 5 in the opposite direction, so that the separation sleeve 5 drives the fixed rod 14, the fixed plate 15 and the drag spring 31 to rotate in the opposite direction through the fixed clamp 13 on one side. At the same time, the separation sleeve 5 will drive the outer push block 6 to rotate in the opposite direction and reset. Then the push block 6 pushes the matching block 8 to one side, so that the matching block 8 slides and resets. 8 drives the transmission sleeve 7 to slide and reset along the guide rail 29, and the transmission sleeve 7 will also drive the inner abutment groove 20 to slide and reset. Due to the chamfer design of one side of the inner wall of the abutment groove 20 and one side of the outer wall of the abutment block 21, the inner wall of the abutment groove 20 gradually presses the abutment block 21 inward, so that the abutment block 21 moves inward and resets. The abutment block 21 will also squeeze the abutment spring 32 on one side, so that the abutment block 21 drives the plug bracket 22 on one side to gradually lock into the plug groove 23. At the same time, the transmission sleeve 7 will squeeze the spring spring 12. When the separation sleeve 5 is completely reset, one end of the plug bracket 22 is reinserted into the plug groove 23 to form a locking relationship. At this time, the clamping bracket 13 just drives the clamping rod 14 and other components to rotate to the original clamping position. The corresponding position of slot 17 is reached, and then the drag spring 31 resets and pulls the clamping plate 15, causing the clamping plate 15 to slide one side of the clamping rod 14 inward. Then, one end of the clamping rod 14 will be reinserted into the original clamping slot 17. Then, the action plate 9 is rotated in the forward direction, causing the action plate 9 to drive the action hole 11 and the action slot 10 to rotate in the forward direction. When the action hole 11 rotates again to the position concentric with the support plate 19, the support spring 30 resets and pushes the locking sleeve 16, causing the locking sleeve 16 to slide and reset. The locking sleeve 16 will also drive one side of the support rod 18 and the two support plates 19 to slide and reset. When the support spring 30 is fully reset, the support plate 19 at the top of the support rod 18 moves back to the original side of the action plate 9, and then the action plate 19 is rotated in the reverse direction. When the action plate 9 is reset, the action plate 9 drives the action hole 11 and the action groove 10 to rotate and reset to a position that does not correspond to the support plate 19 and the support rod 18. At this time, the support rod 18, together with the top support plate 19, supports the locking sleeve 16 to one side of the action plate 9, so that the locking sleeve 16 cannot slide easily. Then, the inner wall of the locking sleeve 16 will limit the outer wall of the clamping plate 15 again, so that the clamping plate 15 and the clamping rod 14 cannot slide outward. Then, the clamping rod 14 and the clamping groove 17 cooperate to form a rotation limit on the clamping frame 13, preventing the separation sleeve 5 from rotating accidentally, thereby realizing the convenient and stable installation of the implantation sleeve 3. Then, the other implantation sleeves 3 are locked together according to the above steps, thereby realizing the stable fixation of the replacement storage rack 24.
[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
