Description

Technical Field

[0001] This utility model relates to the field of automated welding equipment technology, and in particular to a chip welding machine device for filler production. Background Technology

[0002] In industrial production, packing materials, especially sheet-shaped packing materials, are widely used. In the manufacturing process of many packing products, multiple packing sheets need to be connected and fixed by intermittent welding to form specific structures or components.

[0003] Currently, in the packing material production field, the automation level of this piece welding process is generally low. Many production lines still rely on manual or semi-automated operations. For example, workers manually grab packing pieces from the loading area, place them on the fixtures at the welding station, manually adjust their alignment, and then start the welding equipment to weld.

[0004] This production method, primarily based on manual operation, has significant shortcomings. First, workers' operating speed and physical strength are limited, resulting in low overall production efficiency and high labor intensity. More importantly, the precision of manual grasping, placing, and alignment processes is difficult to guarantee, and is highly susceptible to the influence of operator skill and fatigue, leading to unstable welding position accuracy and poor product consistency in the final product. Existing simple equipment often cannot achieve precise linkage and automation of grasping, transferring, and welding actions, making it difficult to meet the demands of modern production for high efficiency and high precision.

[0005] Therefore, this utility model proposes a chip welding machine device for filler production to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a chip welding machine device for filler production, which aims to improve the problems of low automation, low production efficiency due to reliance on manual operation, unstable welding position accuracy, and poor product consistency in the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a chip welding machine device for filler production, comprising a conveyor belt, a motor screw structure, a robotic arm and a welding assembly, wherein the base of the robotic arm is slidably connected to the motor screw structure, the welding assembly is disposed on one side of the conveyor belt, and the chip welding machine device for filler production further comprises a clamping assembly. The clamping assembly is fixedly connected to the end of the robotic arm. The clamping assembly includes a hollow block, a cylinder, a clamping plate, a rotating plate, a linkage rod, and gears. The hollow block is fixed to the robotic arm. The main body of the cylinder is fixed to the inner wall of the hollow block. The clamping plates are symmetrically rotatably connected to the hollow block. The rotating plate is coaxially fixed to one of the clamping plates. One end of the linkage rod is hinged to the output end of the cylinder, and the other end of the linkage rod is hinged to the rotating plate. The gears mesh with each other and are respectively coaxially fixedly connected to the clamping plates. Preferably, the welding assembly includes a housing, a first motor, a threaded rod, a moving frame, a hydraulic cylinder, a slider, a welding column, and a linkage column. The first motor is fixed to the housing. The threaded rod is rotatably connected to the inside of the housing and is driven by the first motor. The moving frame is threaded to the threaded rod and slidably connected to the inner wall of the housing. The hydraulic cylinder is fixed to the moving frame. The slider is slidably connected to the moving frame and driven by the output end of the hydraulic cylinder. The welding column is closably connected to the moving frame. The linkage column is connected between the slider and the welding column. Preferably, the welding assembly further includes a limiting post, the two ends of which are fixed to the movable frame, and the slider has a through hole and is slidably sleeved on the outer wall of the limiting post; Preferably, there are two linkage columns, one end of each linkage column is rotatably connected to both sides of the slider, and the other end is rotatably connected to the corresponding welding column. Preferably, the clamping assembly further includes another rotating plate, which is coaxially fixed with the other clamping plate. The linkage rod is a forked rod, with one end of the forked rod hinged to the output end of the cylinder, and the two ends of the forked rod respectively hinged to the two rotating plates.

[0008] This utility model has the following beneficial effects: 1. This utility model, by setting up a conveyor belt, a motor screw structure and a robotic arm, and having the robotic arm cooperate with the clamping component and the welding component, realizes a fully automated operation process of packing sheets from conveying, gripping, positioning to welding. It solves the problems of low production efficiency, unstable welding position and poor product consistency caused by manual or semi-automatic operation in the prior art, and achieves the goal of improving production efficiency and ensuring product quality stability.

[0009] 2. This utility model solves the problem of uneven clamping force or asynchronous movement that may exist in traditional clamps, which leads to unstable or eccentric material clamping, by using a cylinder-driven connecting rod in the clamping assembly and controlling the opening and closing of a pair of clamping plates through a meshing gear synchronization mechanism. It achieves the effect of accurate clamping and positioning and stable and reliable movement.

[0010] 3. This utility model achieves the overall lifting and positioning of the welding head by using a motor screw mechanism in the welding assembly, and independently sets up a hydraulic cylinder drive linkage mechanism to pressurize the welding column.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0014] Reference Figures 1-6 The present invention provides an embodiment of a filler production chip welding machine device, comprising a conveyor belt 1, a motor screw structure 2, a robotic arm 3, and a welding assembly 4. The base of the robotic arm 3 is slidably connected to the motor screw structure 2, enabling the robotic arm 3 to perform a wide range of linear movements under the drive of the motor screw structure 2. The welding assembly 4 is disposed on one side of the conveyor belt 1 and is used to perform welding operations on the filler chips gripped and positioned by the robotic arm 3. The device also includes a clamping assembly 5, which is fixedly connected to the end of the robotic arm 3 and is used to complete the precise gripping and release of the filler chips on the conveyor belt 1. Specifically, the clamping assembly 5 includes a hollow block 501, a cylinder 502, two clamping plates 503, two rotating plates 505, a linkage rod 504, and two gears 506. The hollow block 501 serves as a mounting base fixed to the robotic arm 3. The main body of the cylinder 502 is fixed to the inner wall of the hollow block 501, serving as the power source for the entire clamping assembly 5. The two clamping plates 503 are symmetrically rotatably connected within the hollow block 501 for directly clamping the packing sheet. The two rotating plates 505 are coaxially fixed to the two clamping plates 503 respectively, for transmitting driving torque. The linkage rod 504... One end of 04 is hinged to the output end of cylinder 502, and the other end of linkage rod 504 is hinged to one of the rotating plates 505, thereby converting the linear motion of cylinder 502 into the rotational motion of rotating plate 505. Two gears 506 mesh with each other and are coaxially fixedly connected to two clamping plates 503 respectively. Through gear meshing synchronization, it is ensured that when cylinder 502 drives one clamping plate 503 to rotate, the other clamping plate 503 can rotate synchronously with equal size and opposite direction, ultimately realizing the synchronous convergence or opening of the two clamping plates 503. The welding assembly 4 includes a housing 401, a first motor 402, a threaded rod 403, a moving frame 404, a hydraulic cylinder 405, a slider 406, two welding columns 409, and two linkage columns 408. The housing 401 serves as the mounting frame for the welding assembly 4. The first motor 402 is fixed to the housing 401. The threaded rod 403 is rotatably connected inside the housing 401, and the output shaft of the first motor 402 is connected to the upper end of the threaded rod 403 via a coupling to drive the threaded rod 403 to rotate. The moving frame 404 is threadedly connected to the threaded rod 403. At the same time, the side wall of the moving frame 404 is also provided with a limit groove and is slidably connected to the inner wall of the housing 401. When the first motor 402 drives the threaded rod 403 to rotate, it can drive the moving frame 404 to move up and down along the axial direction of the threaded rod 403. The hydraulic cylinder 405, mounted on the movable frame 404, drives the slider 406 at its output end. The two sides of the slider 406 slide and engage with the limiting grooves on the side wall of the movable frame 404, improving the guiding accuracy and stability of the slider 406's movement. The welding assembly 4 also includes a limiting post 407, with both ends of the limiting post 407 fixed to the movable frame 404. The slider 406 has a through hole and slides onto the outer wall of the limiting post 407. Two welding posts 409 are rotatably connected to the movable frame 404. One end of two linkage posts 408 is rotatably connected to both sides of the slider 406, and the other end is rotatably connected to the corresponding welding post 409. Through this connection method, when the hydraulic cylinder 405 pushes the slider 406 to move, the slider 406 can synchronously drive the two welding posts 409 to converge or open through the two linkage posts 408. This two-stage motion structure, which combines the lifting and positioning achieved by the motor screw with the pressure welding achieved by hydraulic pressure, ensures precise control and strong execution of the welding action. The clamping assembly 5 also includes another rotating plate 505, which is coaxially fixed with another clamping plate 503. The linkage rod 504 is a forked rod, with one end of the forked rod hinged to the output end of the cylinder 502, and the two ends of the forked rod respectively hinged to the two rotating plates 505. In order to facilitate the assembly and subsequent maintenance of internal parts and to provide a wide operating space for clamping operations, the hollow block 501 of the clamping assembly 5 has a U-shaped opening facing downwards, and the rotation axes of the two clamping plates 503 are horizontally set on the two side walls of the hollow block 501. Furthermore, in order to ensure the smooth power transmission from the first motor 402 to the threaded rod 403, and to absorb vibration and compensate for minor axial deviations that may occur during installation, the output shaft of the first motor 402 is connected to the upper end of the threaded rod 403 via a coupling. The side wall of the moving frame 404 is provided with a limiting groove, and the two sides of the slider 406 slide in the limiting groove. This structure, together with the limiting post 407, can more reliably constrain the movement trajectory of the slider 406 and prevent deflection under the high-speed or heavy-load drive of the hydraulic cylinder 405.

[0015] Working principle: When it is necessary to grasp the packing sheet, the cylinder 502 installed inside the clamping assembly 5 is activated. The output end of the cylinder 502 pushes the linkage rod 504 to move, and the linkage rod 504 in turn drives the rotating plate 505 hinged to it to rotate around the axis. Since the rotating plate 505 is coaxially fixed with one of the clamping plates 503 and the corresponding gear 506, the clamping plate 503 and the gear 506 will rotate synchronously. Through the mutual meshing of the gear 506 and the other gear 506, the other clamping plate 503 is driven to move synchronously in the opposite direction, thereby realizing the synchronous convergence of the two clamping plates 503 to complete the stable grasping of the packing sheet. After the filler sheet is moved to the welding station, the welding assembly 4 starts to work. First, the first motor 402 drives the threaded rod 403 to rotate, and the threaded transmission drives the moving frame 404 to rise and fall as a whole, adjusting the welding mechanism to a suitable welding height. After positioning, the hydraulic cylinder 405 fixed on the moving frame 404 is started. The hydraulic cylinder 405 drives the slider 406 to slide precisely under the guidance of the limit post 407. The movement of the slider 406 is then converted into the convergence action of the two welding posts 409 through the two linkage posts 408, thereby applying sufficient clamping force to the filler sheet and completing the welding operation. In the entire automated process, the conveyor belt 1 is responsible for transporting the filler sheets to be processed to the working range of the robotic arm 3. The motor screw structure 2 drives the robotic arm 3 to perform long-distance precise linear positioning. The joints of the robotic arm 3, together with the clamping assembly 5, complete the picking and precise placement of the filler sheets. Finally, the welding assembly 4 completes the final welding process.
