Description

Technical Field

[0001] The present application relates to the field of assembly devices, and in particular to an automatic installation device for a roller brush end shaft. Background Art

[0002] Reference Figure 1 A roller brush includes a main rod and bristles, wherein the bristles are arranged on the side wall of the main rod, and the end surfaces at both ends of the main rod are provided with insertion holes. After the roller brush is produced, end shafts need to be inserted into the insertion holes at both ends of the main rod. The assembly is usually completed by manually inserting the end shafts into the insertion holes.

[0003] However, during the manual assembly process, since the end shaft and the socket are designed to be tight-fitting, hammering and other actions are required during assembly to complete the assembly of the end shaft, and the assembly efficiency is not high. Summary of the invention

[0004] In order to improve the assembly efficiency of the end shaft, the present application provides an automatic installation device for the end shaft of a roller brush.

[0005] The present application provides a roller brush end shaft automatic installation device, which adopts the following technical solution:

[0006] A roller brush end shaft automatic installation device comprises a plurality of positioning blocks, a plurality of pushing components for pushing the positioning blocks, a placement groove is provided on the positioning block, a feeding component for conveying the end shaft to the placement groove is provided on the positioning block, and a mounting part for installing the end shaft into the roller brush is provided on the side of the pushing component away from the positioning block.

[0007] By adopting the above technical solution, the main rod is placed on the positioning block. After the positioning block clamps the main rod, the feeding assembly transports the end shaft to the placement groove on the positioning block, and the mounting part installs the end shaft into the socket on the main rod, thereby automatically completing the installation of the end shaft and improving the installation efficiency of the end shaft.

[0008] In a specific possible implementation manner, each of the positioning blocks is provided with a positioning groove which is communicated with the placement groove.

[0009] By adopting the above technical solution, the positioning groove positions the position of the main rod on the positioning block, thereby improving the positioning accuracy of the main rod on the positioning block.

[0010] In a specific possible implementation manner, the ejection assembly includes an ejection cylinder and an ejection plate, and the ejection plate is arranged on the piston rod of the ejection cylinder.

[0011] By adopting the above technical solution, the ejection cylinder drives the ejection plate to move, and the ejection plate drives the positioning block to move, which makes it convenient to clamp the main rod on the positioning block and improves the stability of the main rod when assembling the end shaft.

[0012] In a specific feasible implementation scheme, the feeding assembly includes a mounting block, a cut-off cylinder and a material-stopping cylinder, the mounting block is arranged on the positioning block, the mounting block is provided with a feeding hole connected to the placement groove, the cut-off cylinder is arranged on the mounting block, the piston rod of the cut-off cylinder is arranged toward the feeding hole, and the material-stopping cylinder is arranged on the mounting block, and the piston rod of the material-stopping cylinder is arranged toward the feeding hole.

[0013] By adopting the above technical solution, the cut-off cylinder and the material-blocking cylinder can realize the single conveying of the end shaft, which is convenient for accurate conveying of the end shaft. At the same time, it is convenient to control the amount of the end shaft conveyed each time, and reduce the situation where there are too many end shafts and it is inconvenient to install.

[0014] In a specific possible implementation manner, a blowing hole communicating with the feeding hole is provided on the side wall of the mounting block.

[0015] By adopting the above technical solution, the blowing hole blows air toward the end shaft in the feeding hole, pushing the end shaft to be transported outside the feeding hole, thereby reducing the situation where the end shaft is retained in the feeding hole due to friction.

[0016] In a specific possible implementation manner, a shock assembly is provided at one end of the mounting block close to the positioning block.

[0017] By adopting the above technical solution, the shock component shocks the end shaft in the feeding hole, thereby reducing the situation where the end shaft is continuously retained in the feeding hole due to friction.

[0018] In a specific possible implementation mode, the shock assembly includes a shock block and a lifting cylinder, the positioning block is provided with a mounting cavity, the lifting cylinder is arranged in the mounting cavity, and the shock block is arranged on the piston rod of the lifting cylinder.

[0019] By adopting the above technical solution, the shock block hits the mounting block, thereby shocking the end shaft in the mounting block, making it easier for the end shaft in the mounting block to escape from the feeding hole.

[0020] In a specific possible implementation mode, a clearance groove for the shock block to be engaged is formed on the mounting block, and a limiting block is provided on the inner wall of the clearance groove.

[0021] By adopting the above technical solution, the positioning groove makes it easier for the shock block to shock the end shaft more directly, and the limit block limits the movement of the end shaft, making it easier for the end shaft to escape from the feeding hole, thereby further improving the conveying efficiency of the end shaft.

[0022] In a specific possible implementation manner, a clearance cavity is provided on the inner bottom surface of the placement groove, and a conveyor belt is provided in the clearance cavity.

[0023] By adopting the above technical solution, the conveyor belt conveys the end shaft to the main rod, and can pull the end shaft in the feeding hole out of the feeding hole, thereby improving the conveying efficiency of the end shaft. It is also convenient for the installation parts to install the end shaft.

[0024] In a specific possible implementation manner, the mounting member is a pushing cylinder.

[0025] By adopting the above technical solution, the piston rod of the pushing cylinder is extended, and the end shaft is pressed into the socket on the main rod, which facilitates the automatic installation of the end shaft and improves the installation efficiency of the end shaft.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Put the end shaft into the placement groove, and then automatically install the end shaft into the socket on the main rod through the installation part, eliminating the process of manual installation and hammering of the end shaft, and improving the installation efficiency of the end shaft;

[0028] 2. The shock assembly can shock the end shaft, reducing the situation where the end shaft is retained in the feeding hole of the mounting block due to friction, thereby improving the conveying stability and efficiency of the end shaft. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following is combined with Figure 2-5 This application is described in further detail.

[0036] Reference Figure 2 and Figure 3 An automatic installation device for the end shaft of a roller brush includes a workbench 1 and two positioning blocks 2. The two positioning blocks 2 are arranged on the workbench 1. The workbench 1 is provided with a push-up assembly 4, which can push the two positioning blocks 2 closer to or farther from each other. A placement groove 6 is provided on each positioning block 2, and a positioning groove 7 connected to the placement groove 6 is provided on each positioning block 2. The main rod 101 of the roller brush is placed between the two positioning blocks 2, and both ends of the main rod 101 are stuck in the positioning groove 7. The push-up assembly 4 pushes the two positioning blocks 2 closer to each other, so that the positioning blocks 2 clamp the main rod 101.

[0037] Reference Figure 2 and Figure 3 The ejection assembly 4 includes an ejection cylinder 41 and an ejection plate 42. The ejection cylinder 41 is fixed on the workbench 1, and the ejection plate 42 is fixed on the piston rod of the ejection cylinder 41. The ejection plate 42 is fixedly connected to the positioning block 2. The piston rod of the ejection cylinder 41 extends to push the two positioning blocks 2 closer to each other, and the piston rod of the ejection cylinder 41 retracts to drive the positioning blocks 2 away from each other.

[0038] Reference Figure 3 and Figure 4 The positioning block 2 is provided with a feeding assembly 3, which includes a mounting block 31, a cut-off cylinder 33 and a blocking cylinder 32. The mounting block 31 is fixed on the positioning block 2. The mounting block 31 is provided with a feeding hole 8 connected to the placement groove 6. The cut-off cylinder 33 is fixed on the mounting block 31. The piston rod of the cut-off cylinder 33 passes through the side wall of the mounting block 31 and extends into the feeding hole. The blocking cylinder 32 is fixed on the mounting block 31. The piston rod of the blocking cylinder 32 passes through the side wall of the mounting block 31 and extends into the feeding hole 8. In the initial state, the piston rod of the blocking cylinder 32 extends out, and the piston rod of the cut-off cylinder 33 retracts. After the end shaft enters the feeding hole 8, the end shaft stays in the feeding hole 8 due to the blocking effect of the piston rod of the blocking cylinder 32. The piston rod of the cut-off cylinder 33 extends out to clamp the other end shaft of the end shaft away from the stopper cylinder 32, and the piston rod of the stopper cylinder 32 retracts, and the end shaft is transported into the placement groove 6. After that, the piston rod of the stopper cylinder 32 falls again, and the piston rod of the cut-off cylinder 33 retracts again. The cooperation of the cut-off cylinder 33 and the stopper cylinder 32 allows only one end shaft to be transported at a time, thereby improving the transport accuracy of the end shaft.

[0039] Reference Figure 3 and Figure 4 The end of the mounting block 31 away from the positioning block 2 is provided with a blowing hole 9 connected to the feeding hole 8. By connecting an air input device such as an air pump to the blowing hole 9, the end shaft in the feeding hole 8 is blown to reduce the situation where the end shaft is retained in the feeding hole 8.

[0040] Reference Figure 2A mounting member 15 is fixed on the workbench 1. In this embodiment, the mounting member 15 is specifically a push cylinder, and the piston rod of the push cylinder is arranged toward the placement groove 6. The piston rod of the push cylinder extends out, and the end shaft is inserted into the socket 103 of the main rod 101 to complete the assembly of the end shaft.

[0041] Reference Figure 3 and Figure 5 The mounting block 31 is provided with a shock assembly 5 at one end close to the positioning block 2. The shock assembly 5 includes a shock block 52 and a lifting cylinder 51. The positioning block 2 is provided with a mounting cavity 12. The lifting cylinder 51 is vertically fixed in the mounting cavity 12. The shock block 52 is fixed on the piston rod of the lifting cylinder 51. The mounting block 31 is provided with a clearance groove 10 for the shock block 52 to be clamped. A limit block 11 is integrally formed on the inner wall of the clearance groove 10.

[0042] Reference Figure 3 and Figure 5 During the conveying of the end shaft, there is a situation where the end shaft is difficult to slide from the feeding hole 8 into the placement groove 6 under the action of airflow and its own gravity due to friction. By setting the shock block 52, after the piston rod of the lifting cylinder 51 is retracted, the end shaft is driven to swing, changing the force direction of the end shaft, making it easier for the end shaft to slide out of the discharge hole. After the piston rod of the lifting cylinder 51 is extended, the shock block 52 hits the mounting block 31, causing the end shaft to vibrate, making it easier for the end shaft to slide from the discharge hole into the placement groove 6.

[0043] Reference Figure 3 and Figure 5 A clearance cavity 13 is provided on the inner bottom surface of the placement groove 6, and a conveyor belt 14 is provided in the clearance cavity 13. The conveyor belt 14 conveys the end shaft to the main rod 101, so that after one end of the end shaft falls into the placement groove 6, the other end of the end shaft is guided to escape from the feeding hole 8, which is convenient for conveying the end shaft.

[0044] The implementation principle of the embodiment of the present application is as follows: the main rod 101 is placed in the positioning groove 7 on the positioning block 2, the piston rod of the push cylinder 41 is extended, and the positioning block 2 clamps the main rod 101 on the workbench 1. The end shaft is automatically transported into the mounting block 31 through a vibration plate, etc., the piston rod of the cut-off cylinder 33 changes from retracting to extending, and the piston rod of the material-blocking cylinder 32 changes from extending to retracting. , and an end shaft is transported. Blow air into the blowing hole 9, the end shaft slides in the placement groove 6, the piston rod of the lifting cylinder 51 shrinks and then extends, and the end shaft is shaken off onto the conveyor belt 14, and the conveyor belt 14 transports the end shaft to the main rod 101, the piston rod of the push cylinder extends, and the end shaft is pressed into the socket 103 on the main rod 101, and the installation of the end shaft is completed.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
