Description

Technical Field

[0001] This utility model belongs to the field of plate mounting machine technology, and in particular relates to a plate mounting machine that can quickly clamp the plates. Background Technology

[0002] A loading machine is a piece of equipment used in the production process, typically used to automatically transfer parts or materials from one workstation to another. Traditional loading machines usually place the board directly on the loading plate and lift it up and down. During the lifting process, the board is easily displaced by gravity or other factors, which can result in inaccurate loading. When the board is transferred to the conveyor for transport, it cannot be calibrated and may cause the board to slip.

[0003] In this regard, patent document with publication number CN223101870U discloses an automatic loading machine for preventing displacement, which includes a main base plate, a support component, a mounting component, a lifting component, a limiting component, a connecting component, and a clamping component. This technology, by setting an anti-displacement structure, can clamp and fix the board during the operation of the loading machine, reducing the probability of the board slipping and preventing damage to the board. However, after in-depth analysis and practical verification, this existing technology still has a significant drawback: its clamping components typically require the independent operation of multiple (usually four) clamping screws. Operators must sequentially rotate the rotating target on top of each screw to move the circular pressure plates downwards and clamp the material. This "multi-point screwing" clamping method is cumbersome, time-consuming, and significantly reduces loading and unloading efficiency. In scenarios requiring frequent material changes and batch production, this inefficient clamping method becomes a bottleneck restricting production cycle time, hindering further improvements in production efficiency.

[0004] Therefore, there is an urgent need for a new type of loading mechanism structure that can significantly improve clamping and releasing speed while retaining effective anti-deviation function. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a fast-clamping board loading machine. This board loading machine, through an innovative linkage drive structure and lateral clamping design, achieves single-action synchronous and rapid clamping and release of the board material, effectively solving the problem of low efficiency in traditional multi-point clamping methods. While ensuring the reliability of anti-deviation, it significantly improves production efficiency.

[0006] In view of this, the present invention provides a board mounting machine capable of rapid clamping, comprising: A support platform, on which boards can be placed; The frame is equipped with a lifting assembly, which can drive the support platform to move up and down on the frame; Two sets of clamping plates are located on both sides of the support platform. Both sets of clamping plates are slidably connected to the support platform, allowing the two sets of clamping plates to move closer to or further away from each other. The linkage drive component is located at the bottom of the support platform. The linkage drive component can simultaneously drive the two sets of clamping plates to move closer or further apart. The two sets of clamping plates close to each other can clamp the plates on the support platform, while the two sets of clamping plates far apart can release the plates on the support platform.

[0007] In this technical solution, when it is necessary to pick up or place the board, the linkage drive component simultaneously drives the two sets of clamping plates to move away from each other, at which time the board can be picked up or placed. After the board is placed on the upper surface of the support platform, the linkage drive component simultaneously drives the two sets of clamping plates to move closer to each other. The two sets of clamping plates contact the two side walls of the board respectively, clamping the board. Then, the lifting component drives the support platform to rise and fall, realizing the stable transfer of the board.

[0008] In the above technical solution, guide columns are provided on both sides of the bottom of the support platform, and two sets of clamping plates are slidably connected to the two sets of guide columns. The clamping plates are provided with guide grooves that can be sleeved on the outside of the guide columns.

[0009] In the above technical solution, the guide post is further defined as a polygonal prism, and the contour of the guide groove is adapted to the contour of the guide post.

[0010] In the above technical solution, the linkage drive component further includes: Two transmission blocks are respectively set on two sets of clamps, and inclined transmission surfaces are provided on the side walls of the two transmission blocks that are far apart from each other. The driving block is slidably disposed at the bottom of the support platform in a direction perpendicular to the movement of the clamping plate. The two ends of the driving block are located on the side of the two transmission blocks that are far apart from each other. Both ends of the driving block are provided with inclined driving surfaces, and the two driving surfaces are in contact with the two transmission surfaces respectively. Two sets of limiting blocks are respectively set at the ends of the two sets of guide columns away from the bearing platform; Two sets of elastic elements are respectively arranged between two sets of clamping plates and two sets of limiting blocks; The driving component can drive the driving block to move in the sliding direction.

[0011] In the above technical solution, the driving component further includes a transmission screw and a transmission screw hole. One end of the transmission screw is rotatably connected to the bottom of the support platform, and the transmission screw hole is set on the driving block. The transmission screw and the transmission screw hole are threadedly connected.

[0012] In the above technical solution, a handwheel is further provided at the end of the transmission screw away from the bearing platform.

[0013] In the above technical solution, a rubber pad is further provided on the side wall of the plywood closest to the board.

[0014] In the above technical solution, each set of clamps includes multiple clamps, which are distributed at intervals along a direction perpendicular to their sliding direction, and adjacent clamps are fixedly connected.

[0015] In the above technical solution, the lifting component further includes: Guide rods, including lifting guide rods, are mounted on the frame; The lead screw is rotatably mounted on the frame, and the lead screw and guide rod are distributed parallel to each other. The power source drives the lead screw to rotate; The support platform is equipped with guide holes and lifting nuts. The support platform is slidably connected to the guide rod through the guide holes, and the lifting nuts are engaged with the lead screw drive.

[0016] The beneficial effects of this utility model are: 1. Through a set of linkage drive components, the synchronous drive of two sets of clamping plates is realized. The operator only needs to perform a simple action (such as rotating a handwheel) to make the two sets of clamping plates move closer or further apart at the same time, thereby completing the clamping or release of the material. This design reduces the clamping time by several times and is particularly suitable for batch production lines that require frequent material changes, significantly improving production efficiency.

[0017] 2. Through the cooperation of the guide post and the guide groove, especially the use of a multi-faceted prism design, the clamping plate is effectively prevented from rotating during movement and use, ensuring the accurate direction of the clamping force.

[0018] 3. The screw is used as the driving component. The inherent self-locking characteristic of the screw and screw hole ensures that the clamping force can be reliably maintained even when the operation is stopped, and it will not loosen due to equipment vibration, thus ensuring stability during the lifting process.

[0019] 4. The linkage drive components are mainly integrated at the bottom of the support platform, resulting in a compact structure and small space occupation. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] Example 1 This embodiment provides a loading machine that can quickly clamp plates, mainly used for lifting and transferring rectangular plates or plates with parallel sidewalls on both sides. The loading machine includes a support platform 1, a frame 2, a lifting assembly, two sets of clamping plates 4, and a linkage drive assembly 5. Please see Figure 1 and Figure 2 The frame 2 serves as the support for the entire machine. The frame 2 has a base and two uprights spaced apart on both sides of the base. For example, the frame 2 can be welded from steel. A guide rod 301 is fixedly installed vertically on one upright. There can be multiple guide rods 301. A lead screw 302 is installed vertically on the other upright. The lead screw 302 can be rotatably installed on the upright through bearings. A power source 303 for driving the lead screw 302 to rotate is connected to the end of the lead screw 302. The power source 303 can be a servo motor and is installed on the upright. Please see Figures 1-3 In any of the attached drawings, the support platform 1 can be made of steel plate. The upper surface of the support platform 1 is a flat surface that can stably place the plate. The support platform 1 has a guide hole 101 that slides with the guide rod 301. A linear bearing can be installed in the guide hole 101 to reduce friction. At the same time, a lifting nut 102 that matches the lead screw 302 is fixedly installed on the support platform 1. When the servo motor drives the lead screw 302 to rotate, the support platform 1 can make precise vertical lifting and lowering movements along the guide rod 301 through the transmission of the lead screw 302 nut pair. In this embodiment, the lead screw 302 can be a trapezoidal lead screw or a ball screw with self-locking characteristics. When the power source 303 stops driving, the lead screw 302 and the lifting nut 102 can form a self-lock to prevent the support platform 1 from falling on its own under the action of gravity, thereby ensuring the stability of the process of picking up and placing the board. Please see Figures 3-5 The bottom of the support platform 1 is provided with a fixing frame, which is formed by two U-shaped metal frame structures. The fixing frame can be welded to the bottom of the support platform 1. Horizontally placed guide columns 6 are installed on both sides of the fixing frame. The guide columns 6 can be installed on the fixing frame by threaded fasteners. Preferably, the guide columns 6 are polygonal prisms. Two sets of clamping plates 4 are set corresponding to these two sets of guide posts 6. Each set of clamping plates 4 can be formed by a long strip of steel plate or multiple small clamping plates 4 spaced apart and fixed by connectors. The clamping plates 4 are machined with rectangular guide grooves that are consistent with the cross-sectional shape of the rectangular guide posts 6, so that the clamping plates 4 can be fixed in the vertical direction along the guide posts 6, but can slide smoothly in the horizontal direction. When the clamping plates 4 adopt a structure of multiple small clamping plates 4 spaced apart, the number of guide posts 6 can be the same as the number of small clamping plates 4. Each small clamping plate 4 is provided with a guide groove, and each small clamping plate 4 is slidably connected to a guide post 6 to ensure the stable movement of the clamping plates 4. On the inner side of the clamping plate 4 facing the board, a rubber pad 7 is fixed by adhesive or screws. When the board is clamped, the rubber pad 7 contacts the side wall of the board to avoid the clamping force from damaging the board. The linkage drive component 5 is located at the bottom of the support platform 1. The linkage drive component 5 can simultaneously drive the two sets of clamping plates 4 to move closer to each other or further away from each other. When the two sets of clamping plates 4 move closer to each other, they can clamp the plate on the support platform 1. When the two sets of clamping plates 4 move further away from each other, they can release the plate on the support platform 1. Please refer to the details. Figures 3-5 Below the inner side of each of the two clamping plates 4, a transmission block 501 is fixed. On the outer side of the two transmission blocks 501 that are far apart from each other, a transmission surface 5011 inclined from the inside to the outside is machined. A driving block 502 is slidably mounted on the fixed frame so that the driving block 502 can slide horizontally in a direction perpendicular to the sliding of the clamping plate 4. Inclined driving surfaces 5021 are also machined at both ends of the driving block 502. These two driving surfaces 5021 are in contact with the inclined surfaces of the transmission surfaces 5011 on the two transmission blocks 501 respectively. At the end of each guide post 6 furthest from the fixed frame, a limiting block 503 is installed. The cross-section of the limiting block 503 is larger than that of the guide post 6. On each guide post 6 between the clamping plate 4 and the limiting block 503, a spring serving as an elastic element 504 is fitted. The two ends of the spring are connected to the clamping plate 4 and the limiting block 503, respectively. When the transmission block 501 is not under force, the elastic element 504 can pull the two sets of clamping plates 4 away from each other, so that the two sets of clamping plates 4 are in a state of releasing the plate. When the two transmission blocks 501 are pushed by the driving block 502, the two sets of clamping plates 4 move towards each other, gradually clamping the plate. The movement of the drive block 502 is controlled by a drive component. In this embodiment, the drive component includes a horizontally arranged transmission screw 505 and a transmission screw hole provided on the drive block 502. Please refer to [link / reference]. Figure 4 and Figure 5 A mounting plate is provided at the bottom of the support platform 1. One end of the transmission screw 505 is rotatably mounted on the mounting plate through a bearing. The other end of the transmission screw 505 passes through the transmission screw hole on the drive block 502 and is fixedly mounted with a handwheel 506. When the operator applies rotational force to the handwheel 506, the transmission screw 505 can be rotated, thereby causing the drive block 502 to move towards or away from the transmission block 501. During the process of the drive block 502 moving towards the transmission block 501, the two drive surfaces 5021 cooperate with the two transmission surfaces 5011 to push the two transmission blocks 501 towards each other, thereby driving the two sets of clamping plates 4 to move closer to each other and clamping the plate. During this process, the elastic element 504 is stretched and deformed. As the drive block 502 moves away from the transmission block 501, the two drive surfaces 5021 separate from the two transmission surfaces 5011. During this process, the elastic force of the elastic element 504 resets and causes the two sets of clamping plates 4 to move away from each other, releasing the plate. Finally, the two transmission surfaces 5011 come into contact with the two drive surfaces 5021 again, ready to clamp the plate again. In this embodiment, the transmission screw 505 may be made of fine thread to increase transmission accuracy and self-locking performance.

[0030] Working principle Loading process: In the initial state or when loading is required, turn the handwheel 506 to move the drive block 502 away from the transmission block 501. At this time, the pressure of the two drive surfaces 5021 on the two transmission surfaces 5011 on the drive block 502 disappears. Under the elastic force of the elastic element 504, the two sets of clamping plates 4 slide along the guide column 6 to both sides. The two sets of clamping plates 4 are in the open state. At this time, the operator can place a stack of plates stably on the upper surface of the support platform 1.

[0031] Rapid clamping process: After placing the plate, turn the handwheel 506 in the opposite direction to move the drive block 502 closer to the transmission block 501. When the drive block 502 moves, its two drive surfaces 5021 and the transmission surfaces 5011 on the two transmission blocks 501 are squeezed. Due to the inclined plane, the horizontal movement of the drive block 502 is decomposed into a lateral thrust on the two transmission blocks 501 (i.e., the two clamping plates 4), forcing them to overcome the elastic force of the elastic element 504 and slide along the guide post 6 towards the center (i.e., the direction where the plate is located). Finally, the rubber pads 7 on both clamping plates 4 simultaneously contact and tightly press the two sides of the plate, firmly clamping the plate in the center of the support platform 1. Due to the self-locking property of the thread, the clamping state is reliably maintained.

[0032] Lifting and Conveying: After clamping is completed, the control system starts the power source 303, drives the lead screw 302 to rotate, and drives the entire support platform 1 and the clamped plates on it to rise smoothly. When the uppermost plate reaches the same height as the discharge conveyor belt, the lifting stops. At this time, the external push rod mechanism pushes the uppermost plate onto the conveyor belt, completing one loading cycle. During the process of the push rod mechanism pushing the plate, the two sets of clamping plates 4 always clamp the plate, ensuring that only the uppermost plate is pushed out. After one plate is pushed out, the lifting assembly drives the support platform 1 to rise a distance equal to the thickness of one plate, preparing for the next loading cycle. Throughout the entire lifting and loading process, the plate is always reliably clamped, with no risk of displacement.

[0033] Unloading: When the entire stack of boards is about to be used up or the type of material needs to be changed, the support platform 1 is lowered to the bottom, and the operator turns the handwheel 506 to release the clamp 4, so that the remaining boards or pads can be removed, completing one work cycle.

[0034] The embodiments of the present invention have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
