Abstract
Description
Technical Field
[0001] This utility model relates to the field of assembly line technology, and in particular to an assembly line conveying mechanism and an assembly line. Background Technology
[0002] Generally, when producing trolley cases, each component needs to be manufactured separately. After manufacturing, they are assembled manually. During the assembly process, the operator needs to assemble the cases on one side of the conveyor line. The cases are transported on the conveyor line, and the operator needs to take the cases to be processed to the workstation and then assemble them at the workstation.
[0003] A search revealed that patent CN220148511U discloses a bag assembly line, but this assembly line has the following shortcomings in use:
[0004] During use, the bags are lifted by a lifting rod, and personnel assemble the bags on the lifting rod. However, when it is necessary to clamp the bags during assembly, the personnel's hands need to be fixed, making it inconvenient to assemble the bags with both hands. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that in the existing technology, the bags are lifted by a lifting rod and assembled by personnel on the lifting rod. However, when it is necessary to clamp the bags during assembly, the personnel's hands need to be fixed, which makes it inconvenient to assemble the bags with both hands. Therefore, this utility model proposes an assembly line conveying mechanism and assembly production line.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An assembly production line includes a machine base, two workbenches are fixedly mounted on one side of the machine base by bolts, the same first fixing plate is fixedly mounted on the inner walls of both sides of the workbenches, two supports are mounted on one side of the machine base, and a pushing mechanism is provided on the supports, which can push the bags onto the workbenches;
[0008] In order to hold the bags, the worktable also includes a clamping mechanism that can clamp the bags when they are on the worktable.
[0009] In one possible design, the pushing mechanism includes a second push plate and a second cylinder for driving the second push plate to move. One side of the second cylinder is fixedly connected to one side of the bracket, and the telescopic part of the second cylinder passes through one side of the bracket and is fixedly connected to one side of the second push plate.
[0010] In one possible design, the clamping mechanism includes two clamping plates, a housing, a bidirectional lead screw, and a first motor for driving the bidirectional lead screw to rotate. One side of the first motor is fixedly connected to one side of the housing. The two ends of the bidirectional lead screw are rotatably connected to the inner walls of the two sides of the housing, respectively. The output end of the first motor passes through one side of the housing and is fixedly connected to one end of the bidirectional lead screw. The top of the worktable has a grid hole. Both clamping plates are grid-shaped and slidably connected to the inner wall of the grid hole. Two sliders are slidably connected to the bottom inner wall of the housing. The bottom of the clamping plates is fixedly connected to the top of the sliders. A lead screw nut is embedded in one side of the slider and is threadedly connected to the bidirectional lead screw.
[0011] In one possible design, a long plate is fixed to one side of the top of the workbench, and a first cylinder is fixed to one side of the long plate. The telescopic part of the first cylinder passes through one side of the long plate and is fixedly provided with a first push plate for pushing the bag onto the machine platform.
[0012] In one possible design, an electric push rod for adjusting the height of the clamping plate is fixedly installed on the top of the first fixed plate, and a top plate is fixedly installed on the telescopic part of the electric push rod. The bottom of the box body is fixedly connected to the top of the top plate.
[0013] In one possible design, four telescopic rods are fixedly installed on the top of the first fixed plate to improve the stability of the top plate, and the telescopic parts of the four telescopic rods are fixedly connected to the four bottom corners of the top plate respectively.
[0014] An assembly line conveying mechanism is used for conveying the assembly production line described above. It includes multiple conveying rollers, one end of each conveying roller is rotatably connected to the inner wall of one side of a machine base, and the other end of each conveying roller passes through one side of the machine base. A housing is fixedly installed on one side of the machine base, and the same rotating rod is rotatably installed on the inner walls of both sides of the housing. Bevel gears are fixedly sleeved on the rotating rod and at one end of each conveying roller and mesh with each other. A second motor for driving the conveying rollers to rotate is fixedly installed on one side of the housing, and the output end of the second motor passes through one side of the housing and is fixedly connected to one end of the rotating rod.
[0015] In this application, during use, the second motor on one side of the housing is started, and the output end of the second motor begins to rotate, driving the rotating rod to rotate inside the housing. When the rotating rod rotates, through the transmission action of the bevel gear, it drives multiple conveyor rollers to rotate synchronously. The bags placed on the conveyor rollers move forward with the rotation of the conveyor rollers under the action of friction, and are conveyed to the workstation along the assembly line. When they reach the workstation, the second cylinder of the pushing mechanism is activated, and the telescopic part of the second cylinder begins to extend, pushing the second push plate towards the bag. After the second push plate contacts the bag, it continuously applies a pushing force, smoothly pushing the bag from the initial position onto the workbench (the top of the workbench is flush with the conveyor rollers). During this process, the operator needs to observe the movement of the bag to ensure that the bag smoothly enters the workbench. The worktable should operate without any deviation or jamming. If any abnormality occurs, immediately stop the second cylinder, investigate and resolve the cause before continuing operation. Based on the height of the bag, activate the electric push rod on top of the first fixed plate. The telescopic part of the electric push rod extends, pushing the top plate fixed to it upwards. During the ascent, the top plate lifts the box fixed on top of it, causing the box to slide upwards within the grid holes on the top of the worktable. Adjust the clamps to a suitable height to accommodate the bag's height and ensure effective clamping. Simultaneously, the four telescopic rods on top of the first fixed plate extend with the ascent, providing stable support and preventing swaying during ascent, ensuring the accuracy and stability of the clamp height adjustment. Activate the first motor of the clamping mechanism. The output of the first motor starts to rotate, driving the fixedly connected bidirectional lead screw to rotate within the box. Since both ends of the bidirectional lead screw are rotatably connected to the inner walls of both sides of the box, and the two clamping plates are connected to the bidirectional lead screw via bottom sliders, during the rotation of the bidirectional lead screw, based on the thread characteristics of the lead screw, the two clamping plates will move relative to each other along the inner wall of the grille holes towards the center, gradually approaching the bag. Once the clamping plates contact the sides of the bag, pressure continues to be applied, firmly clamping the bag onto the worktable, providing stable positioning for subsequent assembly operations. This eliminates the need for manual clamping, facilitating two-handed assembly. After the bag is stably clamped by the clamping mechanism, the operator can perform the corresponding assembly operations on the worktable. After completing the assembly, the first motor is restarted. This causes the two clamping plates to rotate in the opposite direction, driving the double-acting screw to rotate in the opposite direction. At this time, under the action of the double-acting screw, the two clamping plates move in opposite directions along the inner wall of the fence hole, gradually loosening the clamping of the bag and allowing the bag to return to a free state. The first cylinder on one side of the top of the workbench is activated. The telescopic part of the first cylinder extends, pushing the first push plate fixed to it towards the bag. After the first push plate contacts the bag, it applies a pushing force to smoothly push the bag from the workbench onto the conveyor roller on the machine. The conveyor roller transports the bag to the next station. The first cylinder, the second cylinder, the first motor, the second motor, and the electric push rod need to be controlled by an external controller and powered by an external power source. The cylinders need to be connected to an external air source. The first and second motors can be stepper motors.This motor can rotate in both directions; the specific type can be selected according to actual needs. The material, type, and specifications of the bidirectional lead screw can also be selected as needed.
[0016] The beneficial effects of this utility model are as follows:
[0017] In this utility model, the assembly line conveying mechanism and assembly production line, through the clamping mechanism, use a motor-driven bidirectional lead screw to drive the clamping plate to automatically clamp the bag. During the assembly process, the operator does not need to use his hands to fix the bag, which can completely free his hands and allow him to focus more on the assembly operation, significantly improving the flexibility and efficiency of the assembly.
[0018] In this utility model, the assembly line conveying mechanism and assembly production line use a push mechanism to drive a push plate with a cylinder to smoothly push the bags from the conveying rollers to the worktable. The whole process does not require frequent manual handling of the bags, reducing manual operation links and reducing labor intensity.
[0019] In this invention, the clamping mechanism can automatically clamp the bags, eliminating the need for operators to hold the bags by hand during assembly. This completely frees up their hands, allowing them to focus more on the assembly operation and significantly improving the flexibility and efficiency of assembly. The pushing mechanism can smoothly push the bags from the conveyor rollers to the worktable. The entire process does not require frequent manual handling of the bags, reducing manual operation steps and lowering labor intensity. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Example 1
[0028] Reference Figure 1-5 An assembly line, used in the field of assembly production lines, includes: a machine base 1, a workbench 2, a pushing mechanism, a clamping mechanism, and a conveyor roller assembly. The machine base 1 serves as the main frame of the entire assembly line, bearing and coordinating the work of each component; the workbench 2 is used to place bags to be assembled or partially assembled; the pushing mechanism is responsible for pushing the bags onto the workbench 2; the clamping mechanism clamps and fixes the bags on the workbench 2 for subsequent assembly operations; and the conveyor roller assembly realizes the transfer of bags on the assembly line.
[0029] Machine base 1, serving as the supporting foundation for the entire assembly line, is constructed of robust metal to ensure sufficient strength and stability. Two workbenches 2 are bolted to one side of machine base 1, arranged in parallel. Each workbench 2 has a rectangular structure, with a single first fixing plate 11 fixed to its inner walls on both sides. The first fixing plate 11 is horizontally positioned, providing a mounting base for clamping mechanisms and other components. A long plate 18 is fixed to one side of the top of each workbench 2, perpendicular to the top surface of the workbench 2, serving to support and position the first cylinder 3.
[0030] The pushing mechanism is mounted on two supports 5 on one side of the machine base 1. Its function is to push the bags from other positions onto the worktable 2. The pushing mechanism includes a second push plate 6 and a second cylinder 4 for driving the second push plate 6. One side of the second cylinder 4 is fixedly connected to one side of the support 5 by bolts to ensure a secure installation. The telescopic part of the second cylinder 4 passes through one side of the support 5 and is fixedly connected to one side of the second push plate 6. When the second cylinder 4 is working, its telescopic part pushes the second push plate 6 to move horizontally, thereby pushing the bags onto the worktable 2. During the pushing process, the second push plate 6 contacts the bags, and through its large contact area and appropriate pressure, ensures that the bags can be moved smoothly and accurately to the designated position on the worktable 2.
[0031] A clamping mechanism is installed on the workbench 2 to clamp and fix the bag when it is on the workbench 2, preventing the bag from moving during assembly and ensuring assembly accuracy. The clamping mechanism includes two clamping plates 9, a box body 16, a double-acting lead screw 17, and a first motor 15 for driving the double-acting lead screw 17 to rotate. The connection between the first motor 15 and the double-acting lead screw 17 is as follows: one side of the first motor 15 is fixedly connected to one side of the box body 16 by bolts, and both ends of the double-acting lead screw 17 are rotatably connected to the inner walls of both sides of the box body 16 by bearings, ensuring that the double-acting lead screw 17 can rotate freely. The output end of the first motor 15 passes through one side of the box body 16 and is fixedly connected to one end of the double-acting lead screw 17 by a coupling. When the first motor 15 is working, its output end drives the double-acting lead screw 17 to rotate.
[0032] The top of the workbench 2 has a grid hole 10. Two clamping plates 9 are both grid-shaped, their shape matching the grid hole 10. Both clamping plates 9 are slidably connected to the inner wall of the grid hole 10, ensuring smooth movement along the extension direction of the grid hole 10. Two sliders are slidably connected to the bottom inner wall of the box body 16. The bottom of the clamping plates 9 is fixedly connected to the top of the sliders by welding. A lead screw nut is embedded on one side of the slider, and the lead screw nut is threadedly connected to a double-acting lead screw 17. When the double-acting lead screw 17 rotates, due to the threaded engagement between the lead screw nut and the double-acting lead screw 17, the two sliders will move towards or away from each other along the axis of the double-acting lead screw 17, thereby driving the two clamping plates 9 to move synchronously, realizing the clamping or releasing operation of the bag. When the two clamping plates 9 move towards each other, they gradually approach the bag and eventually clamp it tightly; when it is necessary to release the bag, the two clamping plates 9 move away from each other, leaving the bag.
[0033] A first cylinder 3 is bolted to one side of the long plate 18. The telescopic part of the first cylinder 3 extends through one side of the long plate 18 and is fixedly mounted with a first push plate 19 for pushing the bag onto the machine base 1. After the bag completes part of the assembly process on the workbench 2, the first cylinder 3 operates, and its telescopic part pushes the first push plate 19 to move horizontally, pushing the bag from the workbench 2 onto the machine base 1 for subsequent conveying or other operations. The shape and size of the first push plate 19 are designed according to the size and shape of the bag to ensure that it can push the bag stably and reliably.
[0034] To accommodate bags of different sizes and shapes and improve the versatility of the clamping mechanism, an electric push rod 13 for adjusting the height of the clamping plate 9 is fixedly installed on the top of the first fixed plate 11. A top plate 14 is fixedly installed on the telescopic part of the electric push rod 13, and the bottom of the box body 16 is bolted to the top of the top plate 14. When the height of the clamping plate 9 needs to be adjusted, the electric push rod 13 operates, and its telescopic part drives the top plate 14 to move up and down, thereby driving the entire clamping mechanism, including the box body 16, the bidirectional lead screw 17, and the clamping plate 9, to move up and down, thus achieving the adjustment of the clamping plate 9's height.
[0035] Meanwhile, to improve the stability of the top plate 14 during its vertical movement, four telescopic rods 12 are fixedly installed on the top of the first fixed plate 11. The telescopic parts of the four telescopic rods 12 are fixedly connected to the four bottom corners of the top plate 14. The telescopic rods 12 play a guiding and supporting role during the vertical movement of the top plate 14, ensuring that the top plate 14 always remains horizontal and avoiding swaying or tilting. This ensures that the clamping plate 9 can be accurately adjusted to the required height, achieving effective clamping of the bag.
[0036] The assembly line conveyor mechanism is used to transport bags on the assembly line. It includes multiple conveyor rollers, one end of which is rotatably connected to the inner wall of one side of the machine base 1 via bearings, and the other end of each conveyor roller passes through one side of the machine base 1. A housing is fixedly installed on one side of the machine base 1, and the same rotating rod 7 is rotatably mounted on the inner walls of both sides of the housing via bearings. Bevel gears 8 are fixedly fitted on the rotating rod 7 and one end of each conveyor roller, and adjacent bevel gears 8 mesh with each other. A second motor for driving the rotation of the conveyor rollers is fixedly installed on one side of the housing. The output end of the second motor passes through one side of the housing and is fixedly connected to one end of the rotating rod 7 via a coupling.
[0037] When the second motor operates, its output drives the rotating rod 7 to rotate, and the bevel gears 8 on the rotating rod 7 rotate accordingly. Through the meshing transmission between the bevel gears 8, the various conveyor rollers rotate synchronously. The bags are placed on the conveyor rollers, and as the conveyor rollers rotate, the bags are continuously conveyed on the assembly line. By adjusting the speed of the second motor, the rotation speed of the conveyor rollers can be controlled, thereby adjusting the bag conveying speed to meet the speed requirements of different assembly processes.
[0038] However, as is well known to those skilled in the art, the working principles and wiring methods of the first cylinder 3, the second cylinder 4, the first motor 15, the second motor, and the electric push rod 13 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0039] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
