Description

Technical Field

[0001] This utility model relates to the field of production line material stacking technology, and in particular to a production line material stacking positioning card holder. Background Technology

[0002] In the field of material stacking technology for highly automated and intelligent modern manufacturing production lines, efficient and stable material stacking has become a core key to ensuring the smooth operation of the production process. With the continuous acceleration of production cycles and the increasing sophistication of products, traditional, extensive material stacking methods are no longer sufficient to meet current production demands. Material stacking not only needs to ensure the materials are neatly arranged in space, forming a standardized and regulated stacking array, but also needs to ensure dynamic stability during the stacking process, effectively avoiding problems such as material tipping and displacement caused by vibration and mechanical displacement. Positioning brackets, as indispensable precision auxiliary components in the material stacking process, accurately position and multi-dimensionally limit the stacked materials.

[0003] In existing positioning fixtures, when dealing with excessively high material stacks, a pressure plate is typically used for positioning to limit the movement and enhance the stability of the stacked materials. Currently, most positioning fixtures rely on screw structures to adjust the pressure plate position, raising and lowering the pressure plate by rotating the screw. However, due to the characteristics of ordinary screw lifting mechanisms, the screw occupies a certain axial space in both working and non-working states. In space-constrained working environments, this greatly limits the flexibility of the positioning fixture and may even prevent proper installation and operation due to insufficient space. Furthermore, production line materials often have varying shapes, and existing pressure plates are mostly rigid flat structures. When pressed down, they cannot adapt to irregularly shaped materials, easily leading to uneven localized stress. This not only makes effective positioning and fixing difficult but may also damage the material surface due to concentrated pressure, affecting material quality. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a material stacking and positioning bracket for production lines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a production line material stacking and positioning card holder, including a base, a surrounding plate fixedly installed on the upper end of the base, and storage slots symmetrically opened on both sides of the surrounding plate, with two connecting seats fixedly installed at the bottom of the two storage slots.

[0006] The upper ends of the two connecting seats are provided with grooves, and each groove is hinged with a folding plate. The middle of the storage slot is provided with a bidirectional adjusting screw. Both ends of the bidirectional adjusting screw are rotatably threaded with movable blocks. The upper and lower ends of each movable block are fixedly installed with two connecting pieces. The upper end of the storage slot is provided with a connecting seat, and the bottom of the connecting seat is provided with a groove. Two folding plates are rotatably installed on the inner side of the groove. The front middle of the enclosure is provided with handles on both sides. The inner side of the handle extends through into the storage slot and is fixedly connected to the end of the bidirectional adjusting screw. The upper end of the connecting seat is fixedly installed with a pressure plate.

[0007] Preferably, the connecting seat 2 extends through to the upper end of the storage groove and the surrounding plate, and both ends of the folding plate are fixedly installed with shafts. The two folding plates located at the bottom of the movable block are respectively hinged to the inner side of the groove 1 through the shafts.

[0008] Preferably, the two folding plates located at the upper end of the movable block are respectively hinged to the inner side of the second groove via shafts. The surface of each connecting piece is provided with through holes adapted to the shafts. The ends of the four folding plates near the movable block are rotatably installed inside the through holes via shafts.

[0009] Preferably, slide rails are provided on both sides of the storage slot, and limit sliders are rotatably connected to both ends of the bidirectional adjusting screw. The two limit sliders are slidably installed inside the slide rails. The side of the bidirectional adjusting screw near the handle passes through the limit slider and is connected to the handle. The slide rail near the handle is provided at the front end of the enclosure.

[0010] Preferably, the lower pressure plate has multiple sealing cavities inside, and each sealing cavity has a contact rod slidably installed inside. The upper end of the contact rod is fixedly installed with a piston ring, and the piston ring is in contact with the inner wall of the sealing cavity.

[0011] Preferably, a compression spring is fixedly installed on the top of the piston ring, the upper end of the compression spring is fixedly installed on the upper end of the sealing cavity, and the bottom of the contact rod extends to the outside of the sealing cavity and is fixedly installed with an anti-slip pressure head.

[0012] Preferably, the upper part of the lower pressure plate has an air chamber, the bottom of which is connected to the interior of multiple sealed chambers, and a solenoid valve is fixedly installed on the top of the lower pressure plate. The bottom of the solenoid valve is connected to the interior of the air chamber and is electrically connected to an external relay.

[0013] Preferably, the four folding plates are diamond-shaped, and the distance between the shafts at the end of the folding plate closest to the movable block is much greater than the distance between the shafts at the end closest to connecting seat one and connecting seat two. The threads at both ends of the bidirectional adjusting screw have opposite directions of rotation, and the thread pitch is 2mm-4mm. The screw hole on the movable block is adapted to the thread of the bidirectional adjusting screw.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. By setting up a lifting mechanism consisting of a bidirectional adjusting screw, a movable block, and a diamond-shaped folding plate, when the handle is turned to drive the bidirectional adjusting screw to rotate, the reverse threads at both ends of the screw drive the movable block to move in opposite directions, causing the folding plate to rotate around the shaft as the fulcrum. This efficiently converts the horizontal displacement of the movable block into the vertical lifting of the connecting seat 2, achieving precise adjustment of the lower pressure plate height. Because of the action inside the storage slot, the folding plate can be completely stored in the storage slot when folded, greatly reducing the axial space occupied in the non-working state and solving the installation and operation limitations in environments with limited space.

[0016] 2. By setting contact rods with compression springs and anti-slip pressure heads inside the lower pressure plate, when the stacking height of materials is different or the surface is irregular, each contact rod extends and retracts independently according to the contour of the material surface. The elastic force of the compression spring makes the anti-slip pressure head fit tightly against the material surface. During the descent, multiple contact rods adaptively adjust the extension and retraction amount according to the surface shape of the material, forming a multi-point uniform elastic pressure. This avoids the local pressure concentration caused by the rigid pressure plate on irregular materials, which leads to surface damage. At the same time, the anti-slip texture of the anti-slip pressure head enhances the friction, achieving stable positioning of materials of different shapes and solving the problem of poor adaptability of traditional rigid pressure plates.

[0017] 3. By setting up an air chamber and a solenoid valve in conjunction, when the contact rod extends and retracts independently with the material surface, the solenoid valve opens synchronously. The piston ring moves upward, allowing the air in the sealed cavity to be discharged from the solenoid valve through the air chamber. After the pressure reaches the set point, the solenoid valve closes, and the air chamber and the sealed cavity form a closed space. The internal air pressure locks the piston ring, ensuring that the contact rod continuously and tightly contacts the material surface. This effectively avoids the problem of uneven pressure caused by different extension and retraction of the contact rod and inconsistent spring deformation due to differences in material height. It ensures that the pressure at each contact point for materials with complex shapes is always uniform and stable, significantly improving the positioning reliability. Attached Figure Description

[0028] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0029] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0030] Example: Reference Figures 1-5 Production line material stacking positioning card holder, including base 1, with a surrounding plate 101 fixedly installed on the upper end of base 1, and storage slots 102 symmetrically opened on both sides of the surrounding plate 101, and two connecting seats 2 fixedly installed at the bottom of the two storage slots 102.

[0031] The upper ends of the two connecting seats 1 2 are provided with grooves 201, and the interior of each groove 201 is hinged with a folding plate 202. The middle of the storage slot 102 is provided with a bidirectional adjusting screw 3. Both ends of the bidirectional adjusting screw 3 are rotatably threaded with movable blocks 302. The upper and lower ends of each movable block 302 are fixedly installed with two connecting pieces 304. The upper end of the storage slot 102 is provided with a connecting seat 2 204. The bottom of the connecting seat 2 204 is provided with a groove 205. The inner side of the groove 2 205 is rotatably installed with two folding plates 202. The front middle of the enclosure 101 is provided with handles 301 on both sides. The inner side of the handles 301 extends through into the storage slot 102 and is fixedly connected to the end of the bidirectional adjusting screw 3. The upper end of the connecting seat 2 204 is fixedly installed with a pressure plate 4.

[0032] Specifically: In actual use, the enclosure 101 forms a lateral barrier from all sides, providing an initial horizontal positioning frame for the materials to be stacked, preventing lateral displacement during stacking. The bidirectional adjusting screw 3 rotates under the drive of the handle 301. Since the threads at both ends rotate in opposite directions, they can simultaneously drive the two movable blocks 302 to slide towards or away from each other, converting the rotational power into a lateral driving force. The movable blocks 302 are hinged to the folding plate 202, both receiving the driving force of the bidirectional adjusting screw 3 to achieve their own displacement and transmitting the displacement to the folding plate 202. By rotating the handle 301... 1. The rotation of the bidirectional adjusting screw 3 drives the movable block 302 to slide along the storage slot 102. The movable block 302 drives the folding plate 202 to rotate around the grooves on the connecting seat 1 2 and the connecting seat 2 204. The rotation of the folding plate 202 and the lever effect convert the horizontal displacement into the vertical lifting and lowering of the connecting seat 2 204, thereby driving the lower pressure plate 4 to adjust its height. This achieves precise positioning of materials with different stacking heights. Throughout the process, all components move in an orderly manner within the storage slot 102, ensuring both the stability and precision of the adjustment. The storage slot 102 also enables a compact layout of the components, improving space utilization.

[0033] Connecting seat 204 extends through to the upper end of storage groove 102 and surrounding plate 101. Both ends of folding plate 202 are fixedly installed with shaft 203. The two folding plates 202 located at the bottom of movable block 302 are respectively hinged to the inner side of groove 1 201 through shaft 203. The two folding plates 202 located at the upper end of movable block 302 are respectively hinged to the inner side of groove 2 205 through shaft 203. The surface of connecting piece 304 is provided with through hole 305 that matches shaft 203. The end of the four folding plates 202 near movable block 302 is rotatably installed inside the through hole 305 through shaft 203.

[0034] Specifically: In actual use, the folding plate 202 is hinged to the connecting seat 1 2, connecting seat 2 204 and movable block 302 respectively through the two end shafts 203. The horizontal displacement of the movable block 302 is converted into its own rotational motion, and then the rotation drives the connecting seat 2 204 to achieve vertical lifting. When the bidirectional adjusting screw 3 drives the movable block 302 to move in opposite directions, the movable block 302 drives the shaft 203 to move synchronously through the through hole 305 on the connecting piece 304. The shaft 203 drives the folding plate 202 to rotate with the shaft 203 in the groove 1 201 and the groove 2 205 as the fulcrum. The two ends of the folding plate 202 rotate together under the constraint of the shaft 203, so that the horizontal driving force is smoothly converted into the vertical lifting force of the connecting seat 2 204, and finally realizes the precise height adjustment of the lower pressure plate 4, providing reliable limit support for material stacking.

[0035] The storage slot 102 has slide rails 306 on both sides. Both ends of the bidirectional adjusting screw 3 are rotatably connected to limit sliders 307. The two limit sliders 307 are slidably installed inside the slide rails 306. The side of the bidirectional adjusting screw 3 near the handle 301 passes through the limit sliders 307 and is connected to the handle 301. The slide rail 306 near the handle 301 is provided at the front end of the enclosure 101. The lower pressure plate 4 has multiple sealing cavities 401 inside. The sealing cavity 401 has a contact rod 403 slidably installed inside. The upper end of the contact rod 403 is fixedly installed with a piston ring 404. The piston ring 404 fits against the inner wall of the sealing cavity 401. The top of the piston ring 404 is fixedly installed with a compression spring 402. The upper end of the compression spring 402 is fixedly installed at the upper end of the sealing cavity 401. The bottom of the contact rod 403 extends to the outside of the sealing cavity 401 and is fixedly installed with an anti-slip pressure head 405.

[0036] Specifically: In actual use, the slide rail 306 provides a precise sliding path for the limiting slider 307, ensuring that the screw moves up and down axially without radial deviation. The limiting slider 307 connects the bidirectional adjusting screw 3 and the slide rail 306, sliding along the slide rail 306 with the axial movement of the screw and supporting the rotational movement of the screw, keeping the screw axially stable during rotation and preventing tilting due to uneven force. When the contact rod 403 is compressed, the spring contracts to store potential energy, and when released, it pushes the contact rod 403 to reset, ensuring that the anti-slip pressure head 405 is always tightly in contact with the material surface, forming elastic pressure. The piston ring 404 is fixed to the top of the contact rod 403, preventing the contact rod 403 from falling out of the sealing cavity 401 and evenly transmitting the elastic force of the compression spring 402 to the contact rod 403, ensuring balanced force transmission. The anti-slip pressure head 405 increases the friction with the material surface, and together with the elastic pressure, enhances the clamping stability of the material, preventing the material from sliding during the limiting process.

[0037] The upper part of the lower pressure plate 4 has an air chamber 406. The bottom of the air chamber 406 is connected to the interior of multiple sealed chambers 401. A solenoid valve 407 is fixedly installed on the top of the lower pressure plate 4. The bottom of the solenoid valve 407 is connected to the interior of the air chamber 406 and is electrically connected to an external relay. The four folding plates 202 have a rhomboid structure. The distance between the shafts 203 of the folding plates 202 near the movable block 302 is much larger than the distance between the shafts 203 near the connecting seat 1 and the connecting seat 204. The threads at both ends of the bidirectional adjusting screw 3 have opposite directions and the thread pitch is 2mm-4mm. The screw holes 303 on the movable block 302 are adapted to the threads of the bidirectional adjusting screw 3. The multiple folding plates 202 utilize their diagonal characteristics and the difference in the distance between the shafts 203 at both ends to form an efficient force transmission structure. Combined with the geometric stability of the rhomboid structure, this ensures that the force is minimally lost and has a clear direction during transmission, providing structural support for the precise lifting and lowering of the lower pressure plate 4 and meeting the adjustment requirements for different stacking heights.

[0038] The working principle of this utility model is as follows: In specific use, the material to be stacked is first placed on the upper part of the base 1. The surrounding plate 101 forms a lateral enclosure from all sides to achieve the initial horizontal positioning of the material and prevent lateral displacement during the stacking process. When the material is stacked to the height that needs to be pressed down to limit, the operator rotates the handle 301 at the front end of the surrounding plate 101. The handle 301 drives the bidirectional adjusting screw 3 to rotate synchronously in the storage groove 102. Since the threads at both ends of the screw turn in opposite directions and are adapted to the screw holes 303 of the movable block 302, it will drive the two movable blocks 302 to move in opposite directions along the slide rails 306 on both sides of the storage groove 102.

[0039] As the movable block 302 approaches, the connecting plates 304 at its upper and lower ends drive the folding plate 202 to rotate via the shaft 203. The rotation of the folding plate 202 adjusts the body angle, thereby generating an upward force. The top folding plate 202 converts the horizontal displacement of the movable block 302 into the vertical lifting force of the connecting seat 204. During this process, the bidirectional adjusting screw 3 moves upward with the rotation of the folding plate 202, while the limiting slider 307, which is rotatably connected to both ends of the screw, slides upward synchronously along the slide rail 306, guiding and constraining the axial movement of the screw, ensuring that the rotation of the folding plate 202 and the transmission of force are always in a stable state, so that the connecting seat 204 can drive the lower pressure plate 4 to rise precisely.

[0040] When the lower pressure plate 4 descends and contacts the material surface, the contact rod 403 inside the lower pressure plate 4 first contacts the material. As the lower pressure plate 4 continues to descend, the contact rod 403 slides upward under the reaction force. The piston ring 404 at the upper end of the contact rod moves upward synchronously within the sealing cavity 401, compressing the compression spring 402 at the top. The elastic potential energy of the spring causes the anti-slip pressure head 405 to tightly adhere to the material surface. At this time, the solenoid valve 407 opens synchronously, and the air in the sealing cavity 401 is discharged from the solenoid valve 407 through the air chamber 406, ensuring that the contact rod 403 can adaptively adjust its extension and contraction according to the irregular shape or height difference of the material surface without obstruction. When the contact rod 403 is fully pressed into place, the solenoid valve 407 is closed manually by an external relay. The air chamber 406 and each sealing cavity 401 form a closed space, and the internal air pressure locks the position of the piston ring 404, so that the contact rod 403 maintains a multi-point uniform elastic pressure. This avoids material damage caused by rigid contact and enhances the friction through the anti-slip pressure head 405, improving the limiting stability.

[0041] When picking up or putting down materials, the handle 301 is rotated in the opposite direction, and the bidirectional adjusting screw 3 drives the movable block 302 to move in opposite directions. The folding plate 202 rotates in the opposite direction and unfolds. The screw moves downward as the folding plate 202 resets. The limiting slider 307 slides down synchronously along the slide rail 306 to maintain the guiding constraint. At the same time, the solenoid valve 407 opens to release the air pressure, and the compression spring 402 pushes the contact rod 403 to reset. Finally, the folding plate 202 is folded and stored in the storage slot 102. The connecting seat 204 drives the lower pressure plate 4 to rise and reset, which greatly reduces the space occupied and facilitates subsequent operation and storage.
