Description

Technical Field

[0001] The utility model relates to the technical field of assembly line processing, and specifically discloses an assembly line conveying auxiliary device. Background Technique

[0002] An assembly line is an industrial production organization method. Its core idea is to decompose the production process into multiple continuous processes. Each process is responsible for being completed by specialized workers or equipment. The products flow sequentially between these processes, and finally the entire production process is completed.

[0003] Through the division of labor and the use of specialized equipment, the assembly line can significantly improve production efficiency and shorten the production cycle. The assembly line production method can reduce labor costs, reduce raw material waste, and due to the improvement of production efficiency, the cost per unit product is also reduced.

[0004] For example, the utility model with the authorization announcement number CN211077298U discloses a conveying device for an automated assembly line, including a vertical channel steel, a fixed channel steel, a first fixing plate, a second fixing plate, rollers, stabilizing columns, anti-slip rubber pads, connecting channel steels, a protective plate, a connecting track, a motor fixing box, a runner, a connecting rotating rod, a fixing ring, and a rotating motor. The beneficial effects of the utility model are: the connecting rotating rod is rotatably arranged at both end points of the connecting channel steel, and the protective plate is fixedly surrounded and fixed outside the connecting rotating rod to protect the connecting rotating rod and eliminate potential safety hazards. The rotating motor is directly connected to the internal connecting shaft of the connecting rotating rod and is locked by screwing a fastening screw. Through the direct connection between the connecting rotating rod and the rotating motor, the synchronous rotation of the rotating motor and the connecting rotating rod is realized. The connecting track is fixedly wrapped around the outside of the runner to ensure the transmission linkage of the conveying device.

[0005] Currently, for assembly line processing, products are mainly transported through a conveyor belt structure, enabling workers to operate on the products at intervals while pressing on the conveyor belt to form assembly line production. Conventional assembly line conveying structures all use a single conveyor belt for transportation. Since the surfaces of some products are smooth, they are extremely likely to roll off the conveyor belt during transportation. At the same time, if the products are assembled on the assembly line, due to the different progress of different workstations, when the progress difference between workstations is too large, it is necessary to appropriately intercept and block the product transportation to ensure that the workstations with a large difference can keep up with the progress and ensure the processing quality of each product. Content of the Utility Model

[0006] In view of this, the purpose of the present utility model is to provide an assembly line conveying auxiliary device to solve the problems of preventing objects from slipping on the conveyor belt mechanism for transporting objects on the assembly line and intercepting and blocking objects when there is a progress difference at a single workstation.

[0007] To achieve the above object, the present utility model provides the following technical solution: A pipeline conveying auxiliary device, including a table conveying mechanism, and a conveying limiting mechanism is arranged at the upper end of the table conveying mechanism;

[0008] The upper end of the conveying limiting mechanism is equidistantly distributed with a conveying blocking mechanism.

[0009] Specifically, the table conveying mechanism includes a workbench, and several workstations are distributed on one side of the workbench. The number of workstations is the same as the number of the conveying blocking mechanisms, and the positions correspond one by one;

[0010] Supporting legs for support are fixed at the lower ends of the workbench and the workstations.

[0011] Specifically, a driving bearing is fixed at the upper end of the workbench, a driving shaft rod penetrates through the inside of the driving bearing, and a driving roller is fixedly sleeved on the surface of the driving shaft rod;

[0012] A motor is further arranged above the workbench. A rotating shaft for driving is arranged inside the motor, and the end of the rotating shaft is fixedly assembled with the driving shaft rod through a coupling.

[0013] Specifically, several symmetrically distributed linkage bearings are further fixed at the upper end of the workbench. A linkage shaft rod penetrates through the inside of the linkage bearing, and a linkage roller is fixedly sleeved on the surface of the linkage shaft rod. Several linkage rollers and a single driving roller are arranged through belt transmission.

[0014] Specifically, the conveying limiting mechanism includes a mounting plate. First cylinders are fixed on both sides of the upper end of the mounting plate. A first piston rod for driving is arranged inside the first cylinder, and a limiting plate is arranged at the end of the first piston rod.

[0015] Specifically, a threaded column is installed at the upper end of the workbench. A built-in sleeve penetrates through the surface of the mounting plate. The built-in sleeve and the threaded column penetrate through each other. A nut is threadedly installed at the end of the threaded column, and a knob is arranged on the outer peripheral wall of the nut.

[0016] Specifically, the conveying blocking mechanism includes a support plate. The lower end of the support plate is installed on the upper end of the limiting plate through a bracket. A second cylinder penetrates through the surface of the support plate. A second piston rod for telescoping is arranged inside the second cylinder, and a blocking strip is installed at the end of the second piston rod.

[0017] Specifically, buffer sleeves are slidably sleeved on both the front and rear sides of the blocking strip. Built-in grooves are formed on both sides of the blocking strip. Springs are arranged inside the built-in grooves. The two ends of the springs are fixedly assembled with the surface of the buffer sleeve and the inner wall surface of the built-in groove respectively.

[0018] The working principle and beneficial effects of this solution are as follows: 1. The tabletop conveying mechanism can serve as the basic working mechanism of the assembly line, ensuring the stable conveying of raw materials or components in product production. A work station is set on one side of the workbench, facilitating simultaneous operation by multiple workers. A conveying limit mechanism is set above the conveyor belt. The conveying limit mechanism can protect both sides according to the size of the conveyed object through a limit plate structure that can move up and down, avoiding the situation where the object is too smooth and rolls off the conveyor belt.

[0019] 2. Based on the contact of the conveying limit mechanism described in 1, a conveying blocking structure is added. When there is a large difference in work progress at different work stations, in order to prevent the current backward work station from accumulating too much work, the conveyed objects can be blocked by the conveying blocking mechanism and gathered at the position of the current backward work station, thus facilitating the quick replenishment of progress and avoiding omission. Especially in the case of product assembly on the assembly line, it can prevent quality problems in product assembly.

The objectives and other advantages of the present utility model can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The tabletop conveying mechanism 1 comprises a workbench 10, and a plurality of workstations 11 are distributed on one side of the workbench 10. The number of the workstations 11 is the same as the number of the conveying intercepting mechanism 3, and the positions correspond one to one. The connection between the workstations 11 and the workbench 10 is fixed and assembled by screws, and the lower ends of the workbench 10 and the lower ends of the workstations 11 are fixed with supporting legs for support.

[0031] A driving bearing 12 is fixed to the upper end of the workbench 10, and the outer wall surface of the driving bearing 12 is fixedly assembled with the workbench 10 through a bracket, and a driving shaft 19 is provided inside the driving bearing 12, and the surface of the driving shaft 19 is interference-fitted with the inner ring wall of the driving bearing 12, and a driving roller 13 is fixedly sleeved on the surface of the driving shaft 19. A motor 14 is also provided above the workbench 10, and the outer wall surface of the motor 14 is fixedly assembled with the surface of the workbench 10 through a bracket, and a rotating shaft for driving is provided inside the motor 14, and the end of the rotating shaft is fixedly assembled with the driving shaft 19 through a coupling;

[0032] A plurality of symmetrically distributed linkage bearings 15 are fixed to the upper end of the workbench 10, a linkage shaft 16 is provided inside the linkage bearing 15, the surface of the linkage shaft 16 is interference fit with the inner ring wall of the linkage bearing 15, a linkage roller 17 is fixedly sleeved on the surface of the linkage shaft 16, and the plurality of linkage rollers 17 and the single driving roller 13 are driven by a conveyor belt 18;

[0033] The conveying limiting mechanism 2 includes a mounting plate 20, which is arranged along both ends of the workbench 10 and corresponds to the feeding and discharging sides of the conveyor belt 18. First cylinders 21 are fixed on both sides of the upper end of the mounting plate 20. A first piston rod for driving is arranged inside the first cylinder 21. A limiting plate 22 is arranged at the end of the first piston rod. Two first piston rods located on the same side and along the feeding and discharging direction of the conveyor belt 18 are connected to the same limiting plate 22. There are two limiting plates 22, which are arranged in parallel with each other.

[0034] A threaded post 23 is installed at the upper end of the workbench 10. A built-in sleeve 24 is penetrated through the surface of the mounting plate 20. The connection position between the built-in sleeve 24 and the mounting plate 20 is fixed by welding. The built-in sleeve 24 and the threaded post 23 penetrate through each other. A nut 25 is threadedly installed at the end of the threaded post 23. The end face of the nut 25 is closely attached to the end face of the built-in sleeve 24. A knob 26 is arranged on the outer circumferential wall of the nut 25. The end of the knob 26 is welded to the surface of the nut 25. The number of the knobs 26 is two and they are evenly distributed.

[0035] The conveying blocking mechanism 3 includes a support plate 30. The lower end of the support plate 30 is installed at the upper end of the limiting plate 22 through a bracket, and the support plate 30 straddles the limiting plates 22 distributed on both sides. A second air cylinder 31 is penetrated through the surface of the support plate 30. The connection position between the second air cylinder 31 and the support plate 30 is fixedly assembled by screws. A second piston rod for telescoping is arranged inside the second air cylinder 31. A blocking strip 32 is installed at the end of the second piston rod. The blocking strip 32 is of a rectangular structure. The blocking strip 32 can be used as a blocking component for the conveyor belt 18 when conveying objects.

Built-in grooves 34 are opened on both sides of the blocking strip 32. Springs 35 are arranged inside the built-in grooves 34. Both ends of the springs 35 are fixedly assembled with the surface of the buffer sleeves 33 and the inner wall surface of the built-in grooves 34 respectively. By the compression to reset of the springs 35, when the buffer sleeves 33 touch the blocked objects, a buffering effect can be achieved.

[0037] During specific implementation

[0038] When pipeline conveying is required, the power supply of the motor 14 is turned on. The motor 14 is connected with a forward and reverse switch through a wire, and the model of the forward and reverse switch is HY2-8. The motor 14 is also plugged into the indoor 220V power socket through a wire plug. Through the forward and reverse switch, the motor 14 can be started, so that the motor 14 drives the drive shaft rod 19 to rotate through the rotating shaft. Thus, the drive shaft rod 19 drives the drive roller 13 to rotate, and further drives the conveyor belt 18 to rotate. The conveyor belt 18 realizes the auxiliary support of transmission through a plurality of linkage rollers 17. The linkage rollers 17 can ensure stable rotation through the linkage shaft rod 16 and the linkage bearing 15.

[0039] During the process of the conveyor belt 18 conveying an object, according to the height of the object, by the telescoping of the first piston rod of the first air cylinder 21, the up and down movement of the limiting plate 22 can be realized, so that the limiting plates 22 distributed on both sides above the conveyor belt 18 can ensure the stable conveyance of the object and prevent it from slipping off from both sides of the conveyor belt 18.

[0040] When the progress of a certain work station 11 is slow, the piston rod of the second cylinder 31 can be extended and retracted to drive the stop bar 32 to move up and down and approach the conveyor belt 18, so as to block the object transfer. When the object contacts the stop bar 32, the buffer sleeve 33 slides on the stop bar 32, and the spring 35 is compressed and reset, so as to achieve the buffer protection for the object contact.

[0041] When it is necessary to remove the transfer limit mechanism 2 and the transfer blocking mechanism 3, hold the knob 26 by hand to drive the nut 25 to rotate and generate relative thread movement with the threaded column 23, so as to disconnect the inner sleeve 24 from the threaded column 23. Furthermore, the transfer limit mechanism 2 and the transfer blocking mechanism 3 can be removed as a whole.

[0042] The above are only the embodiments of the present invention. Common knowledge such as specific structures and characteristics known in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the present invention.
