[0028] The present invention provides a fixture lifting device 100.

[0029] Please refer to Figure 1, in an embodiment of the present invention, the jig lifting device 100 includes a frame 1, a loading mechanism 2, a pushing mechanism 3, and a lifting mechanism 4; the frame 1 is provided with a lifting station; the loading mechanism 2 is arranged on one side of the frame 1, and the loading mechanism 2 is used to transfer the workpiece onto the frame 1; the pushing mechanism 3 is movably arranged on the frame 1, and the pushing mechanism 3 is used to push the workpiece to the lifting station; the lifting mechanism 4 is arranged at the lifting station, and the lifting mechanism 4 is used to lift the workpiece.

[0030] In the technical solution of the present invention, after the loading mechanism 2 transfers the workpiece onto the frame 1, the pushing mechanism 3 can actively push the workpiece directly to the lifting station, avoiding the problem of inaccurate positioning. Then, the lifting mechanism 4 lifts the workpiece in the vertical direction, thereby improving the production efficiency.

[0031] Specifically, in an embodiment of the present invention, please refer to Figure 1 and Figure 2 , the pushing mechanism 3 includes a movable seat 31 and a pushing plate 32. The movable seat 31 is movably arranged on the frame 1, and the pushing plate 32 is arranged on the movable seat 31. The pushing plate 32 is used to push the workpiece. The movable seat 31 of the pushing mechanism 3 is movably arranged on the frame 1. By precisely controlling the movement of the movable seat 31, the pushing plate 32 can be driven to achieve precise pushing of the workpiece, ensuring that the workpiece can reach the lifting station accurately and effectively avoiding the positioning deviation problem that may occur in the traditional slideway or ramp guiding method. By adjusting the movement range of the movable seat 31 and the size and shape of the pushing plate 32, the pushing mechanism 3 can adapt to the pushing requirements of light bar jig templates or other similar workpieces with different sizes and shapes, making the entire jig lifting device 100 have a wider applicability and can meet the loading requirements in various production scenarios. At the same time, according to the actual production requirements, the pushing speed and force of the workpiece can be flexibly adjusted by controlling the movement speed of the movable seat 31 and the thrust of the pushing plate 32. For example, when dealing with heavier or higher-friction workpieces, the thrust of the pushing plate 32 can be appropriately increased; for the production link that requires rapid loading, the pushing speed can be increased, so as to better match different production rhythms and workpiece characteristics and improve the overall performance and production efficiency of the equipment.

[0032] Furthermore, in an embodiment of the present invention, please refer to Figure 1 and Figure 2, the movable seat 31 is slidably arranged on the frame 1 along the feeding direction of the feeding mechanism 2, and is located in the lower space of the feeding mechanism 2. The movable seat 31 has a receiving groove, and the push plate 32 is movably arranged in the receiving groove. In this way, the movable seat 31 can be set on the feeding path of the workpiece, and the feeding space of the equipment is fully and reasonably utilized. This layout makes the structure of the entire equipment more compact, and there is no need to occupy too much space to set the push mechanism 3, which can effectively improve the space utilization rate and optimize the layout of the production line. By accommodating the push plate 32 in the receiving groove, when the push mechanism 3 is not working, the push plate 32 can avoid the transmission path of the workpiece to avoid obstructing the normal transmission of the workpiece. When the workpiece needs to be pushed, the push plate 32 can be extended from the receiving groove in time to accurately push the workpiece, realizing the efficient switching of pushing and avoiding, and further improving the coordination and fluency of the equipment operation. This setting enables the push mechanism 3 to cooperate with different feeding mechanisms 2 to adapt to a variety of feeding methods and workpiece transmission requirements. Regardless of whether a belt conveyor, chain conveyor or other form of feeding mechanism 2 is used, as long as the size and position relationship of the movable seat 31 and the push plate 32 are reasonably designed, efficient pushing and avoiding of the workpiece can be achieved, thereby improving the versatility and compatibility of the equipment. In the actual production process, if the feeding process or equipment layout needs to be adjusted and modified, this setting also provides greater convenience. Since the structures of the movable seat 31 and the push plate 32 are relatively independent and easy to adjust, the position, pushing angle and force of the push mechanism 3 can be quickly adjusted according to new production needs without large-scale modification of the entire equipment, thereby improving the adaptability and flexibility of the equipment.

[0033] Furthermore, in one embodiment of the present invention, please refer to Figure 1 , there are two pushing mechanisms 3, and the two pushing mechanisms 3 are arranged on opposite sides of the feeding mechanism 2. That is, the movable seats 31 of the two pushing mechanisms 3 are arranged on both sides of the feeding mechanism 2, which can realize the synchronous pushing of the workpiece, and the workpiece is subjected to more uniform force during the pushing process, reducing the deviation and shaking of the workpiece, and further improving the stability of the pushing. Especially for light bar fixture templates with larger sizes or irregular shapes, this two-way pushing method can better ensure that the workpiece arrives at the lifting station accurately. And the two movable seats 31 move in the same direction, and the movements are more coordinated. Under the command of the control system, the two pushing mechanisms 3 can be started and stopped at the same time, ensuring the continuity and synchronization of the workpiece pushing process, reducing the problems of workpiece deviation and jamming caused by the asynchronous movement of the pushing mechanism 3, and further improving the reliability of the equipment operation.

[0034] Specifically, in one embodiment of the present invention, please refer to Figure 1 and Figure 2, the loading mechanism 2 includes rollers 21 and a first driving motor provided on the frame 1, and the first driving motor drives the rollers 21 to rotate. The rollers 21 have good rotational performance and load-bearing capacity, and can quickly and smoothly convey the light bar fixture template or other workpieces to the frame 1 under the drive of the first driving motor. The rotation of the rollers 21 provides stable support and propulsion force for the workpieces, keeping the workpieces in a stable state during the conveying process, and avoiding unstable phenomena such as unsmooth sliding, jamming, or excessive sliding of the workpieces caused by uneven surfaces, excessive or insufficient friction on the slideway or slope. This stable transmission method helps to improve the conveying accuracy of the workpieces. During the conveying process, the rotation of the rollers 21 can effectively reduce the direct friction between the workpieces and the conveying components. Especially when conveying the light bar fixture template with a relatively smooth or easily scratched surface, this rolling conveying method can better protect the surface quality of the workpieces and reduce the risk of defects such as scratches and abrasions caused by friction, thereby improving the appearance quality and performance stability of the products. Among them, the first driving motor is a linear reduction motor, and the linear reduction motor can achieve high-precision control of the rotation speed of the rollers 21. During the loading process, according to the light bar fixture templates of different sizes and weights, the rotation speed of the rollers 21 can be accurately adjusted to ensure that the workpieces are conveyed to the frame 1 at an appropriate speed.

[0035] Specifically, in an embodiment of the present invention, the lifting mechanism 4 includes a second driving motor, a transmission component, and a lifting plate 41. The second driving motor is provided inside the frame 1, the lifting plate 41 is provided at the lifting station, and the transmission component connects the output end of the second driving motor and the lifting plate 41. The second driving motor can accurately control the lifting height of the lifting plate 41. Through the precise transmission of the transmission component, the lifting plate 41 can lift the light bar fixture template to an appropriate position according to a preset program. The transmission component can smoothly transmit the power of the second driving motor to the lifting plate 41, so that the lifting plate 41 remains stable during the lifting process.

[0036] Among them, the transmission component is a ball screw structure. The ball screw structure is a high-precision transmission structure that can accurately convert the rotational motion of the second driving motor into the linear motion of the lifting plate 41. This precise transmission method enables the lifting plate 41 to move strictly according to the preset displacement and speed during the lifting process, ensuring that the light bar fixture template is lifted to an accurate position, thereby further improving the lifting accuracy.

[0037] The second driving motor is a stepping motor. The stepping motor can rotate with an accurate step angle, and through the control system, micron-level precise control of the lifting height of the lifting plate 41 can be achieved. During the lifting process of the light bar fixture template, this high-precision positioning ability ensures that the workpiece can be lifted to an extremely precise position, meeting the requirements of high-precision processing or assembly, and further improving the product quality and production efficiency.

[0038] Further, in an embodiment of the present invention, please refer to Figure 1 , the jig lifting device 100 further includes a positioning plate 5. The positioning plate 5 is disposed on a side of the frame 1 away from the loading mechanism 2 and is close to the lifting station. On a side of the positioning plate 5 facing the loading mechanism 2, there are two spaced positioning blocks 51. The two positioning blocks 51 are used to abut against and limit the workpiece. The two spaced positioning blocks 51 on the positioning plate 5 can accurately abut against and limit the workpiece, ensuring the accurate position of the workpiece at the lifting station. This mechanical limiting method has higher positioning accuracy and stability compared to simply relying on the pushing mechanism 3 or the lifting mechanism 4 for positioning, and can effectively avoid phenomena such as displacement and shaking of the workpiece during lifting or processing, further improving product quality and production efficiency. At the same time, the setting of the positioning plate 5 and the positioning blocks 51 provides an intuitive operation guide for the operator, enabling the operator to clearly see the positioning position and state of the workpiece. During the loading and lifting processes, the operator can quickly and accurately judge whether the workpiece has reached the designated position according to the indication of the positioning blocks 51, thereby timely adjusting the operating parameters of the equipment or dealing with possible problems, improving the operation convenience of the equipment and the controllability of the production process. By adjusting the position of the positioning blocks 51 or designing positioning blocks 51 with different sizes, the positioning plate 5 can adapt to the positioning requirements of light bar jig templates or other similar workpieces with various sizes and shapes. This enables the entire jig lifting device 100 to quickly switch between different production tasks and product types, improving the versatility of the equipment.

[0039] To facilitate the pushing mechanism 3 to push the workpiece, in an embodiment of the present invention, please refer to Figure 1, the frame 1 is provided with a plurality of pulley blocks arranged at intervals, each pulley block includes a plurality of fixed pulleys 8 arranged at intervals along the feeding direction, and the lifting mechanism 4 includes a plurality of lifting plates 41, each lifting plate 41 is arranged between two pulley blocks. The plurality of fixed pulleys 8 in each pulley block are arranged at intervals along the feeding direction, and can accurately guide the workpiece. During the pushing process, the workpiece can always maintain the correct feeding direction under the guidance of the pulley block, avoid the workpiece from being offset or deviating during the pushing process, improve the accuracy of the workpiece pushing, and ensure that the workpiece can accurately reach the lifting station. The setting of multiple pulley blocks can effectively reduce the friction resistance of the workpiece during the pushing process, and the fixed pulley 8 can enable the workpiece to move more smoothly along the feeding direction, reduce the workpiece position deviation and thrust loss caused by friction, and further improve the stability of the workpiece pushing. And by reasonably adjusting the spacing between the pulley blocks and the position of the lifting plate 41, the setting can adapt to the pushing and lifting requirements of light bar fixture templates or other similar workpieces of different sizes and shapes. Whether the workpiece is long and narrow or short and wide, it can be pushed and lifted stably with the cooperation of the pulley block and the lifting plate 41, which improves the versatility of the equipment. During the loading process, the lifting plate 41 can be retracted under the pulley block without causing any obstruction to the transmission of the workpiece. The workpiece can reach the lifting station quickly and smoothly under the guidance of the pulley block, and then be lifted by the lifting plate 41.

[0040] For precise guidance, in one embodiment of the present invention, please refer to Figure 1 , the positioning plate 5 is provided with two linear guides 6 arranged at intervals on one side facing the feeding mechanism 2, and the lifting mechanism 4 is slidably connected with the two linear guides 6. The linear guide 6 can provide accurate linear motion guidance for the lifting mechanism 4, ensuring that the lifting mechanism 4 moves in a straight line during the lifting and lowering process, effectively avoiding the deviation, shaking and other phenomena of the lifting mechanism 4 during the movement, and further improving the positioning accuracy. The linear guide 6 has good load-bearing capacity and wear resistance, can bear the weight of the lifting mechanism 4 and the workpiece, and at the same time reduce the friction loss during the movement, extend the service life of the equipment, and reduce the maintenance cost and failure rate of the equipment. As a standardized component, the linear guide 6 is convenient for modular design and integration of the equipment. According to different equipment scales and production requirements, the linear guide 6 of appropriate specifications can be selected, the positioning device can be quickly built, and the equipment can be quickly assembled and debugged. At the same time, the linear guide 6 is also easy to integrate with other automation equipment and control systems to realize the automated production and intelligent control of the equipment.

[0041] Further, in one embodiment of the present invention, please refer to Figure 1The jig lifting device 100 also includes two movable plates 7 movably arranged on the frame 1, and the two movable plates 7 are respectively located on opposite sides of the lifting station. The two movable plates 7 are respectively located on opposite sides of the lifting station, and can limit the workpiece in the lateral direction to prevent the workpiece from lateral displacement or shaking during the lifting or waiting process. Cooperating with the positioning block 51 on the positioning plate 5, precise limiting of the workpiece in multiple directions is achieved, further improving the positioning accuracy and stability of the workpiece. The movable design of the movable plate 7 enables it to be flexibly adjusted according to the actual size of the workpiece to meet the positioning requirements of light bar jig templates or other similar workpieces of different widths or lengths. By adjusting the position of the movable plate 7, the workpiece can obtain the best limiting effect on the lifting station, avoiding the problem of inaccurate positioning due to changes in the size of the workpiece, and improving the versatility and flexibility of the equipment.

[0042] Further, in one embodiment of the present invention, the fixture lifting device 100 also includes a feeding detection module, which is arranged on the frame 1 and is arranged near the feeding mechanism 2. After the feeding detection module detects that the workpiece has arrived at the specified position, it can automatically trigger the pushing mechanism 3 to perform the pushing operation. The entire process does not require human intervention, and an automated process from feeding detection to workpiece pushing is realized, which greatly improves the automation level of production, reduces the occupation of human resources, and reduces labor costs. The automated detection and pushing process reduces misoperation caused by human factors. Since the equipment runs according to the preset program, the pushing action of the workpiece is always performed at the correct time and conditions, avoiding equipment failure and workpiece damage caused by irregular or untimely manual operation, reducing the failure rate of the equipment and the scrap rate in the production process, and improving the production quality and stability of the equipment. : The feeding detection module, the pushing mechanism 3 and the lifting mechanism 4 can achieve close collaboration through the control system. This modular design facilitates the overall integration and optimization of the equipment, and can adjust and optimize the parameters of each module according to different production needs and process requirements to achieve the best operating state of the equipment and improve the comprehensive performance and production efficiency of the equipment.

[0043] In an embodiment of the present invention, the fixture lifting device 100 can automatically detect the feeding state of the workpiece by setting up a feeding detection module, realizing an automated process of feeding, pushing, and lifting, improving production efficiency, and reducing manual intervention. The two pushing plates 32 of the pushing mechanism 3 move in the same direction, capable of synchronously and efficiently pushing the workpiece to the lifting station, further shortening the feeding time of the workpiece. The positioning plate 5, the movable plate 7, and the pushing plate 32 of the pushing mechanism 3 work together to limit the workpiece from multiple directions, ensuring the accurate position of the workpiece during the lifting process and improving the positioning accuracy. The lifting mechanism 4 adopts a combination of a stepping motor and a ball screw, capable of quickly and accurately lifting the workpiece to the processing station to meet the requirements of high-precision machining. The structure of each component is simple, easy to maintain and adjust, with strong versatility, capable of adapting to workpieces of different sizes, weights, and shapes, and having high flexibility. The pulley group can reduce the frictional resistance during the pushing process of the workpiece and improve the stability of pushing. The overall design realizes highly automated and intelligent control, and each mechanism works in coordination to ensure the high efficiency, stability, and accuracy of production.

[0044] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
