Description

Technical Field

[0001] This invention relates to the field of chain assembly technology, and in particular to an assembly machine and process for chain assembly. Background Technology

[0002] A chain is a mechanical transmission element composed of a series of interconnected links, used to transmit power or motion. During the assembly process of the inner links of the chain, the assembly machine feeds an inner chain plate into the sleeve feed port, presses an inner chain plate into the bottom of the sleeve, then fits a roller on the top of the sleeve, and finally presses the remaining inner chain plate into the top of the sleeve.

[0003] In existing chain assembly machines, there is a lack of inspection and sorting mechanisms before the top of the sleeve is pressed into the remaining inner chain plate. Due to malfunctions, the outer wall of the sleeve may not be pressed with rollers, and its top may be pressed into the remaining inner chain plate. During chain transmission, due to the lack of rollers, the sleeve and sprocket teeth are in direct contact, which increases sliding friction, leading to abnormal wear, a sharp drop in transmission efficiency, and abnormal noise. Secondly, overload of the chain link rigidity may cause local deformation or even breakage, threatening the safety of the transmission system. In addition, chain links without rollers are prone to stress concentration during high-speed movement, shortening the overall life of the chain. More seriously, if such defects are not detected, a batch of defective products will flow downstream, increasing rework costs and potentially causing equipment failures or safety accidents, seriously affecting production reliability. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the prior art, chain assembly machines lack a detection and sorting mechanism before pressing the top of the sleeve into the remaining inner chain plate. Due to a malfunction, the outer wall of the sleeve may not be pressed into the roller, and its top may be pressed into the remaining inner chain plate. During chain transmission, due to the missing roller, the sleeve and sprocket teeth are in direct contact, which increases sliding friction, leading to abnormal wear, a sharp drop in transmission efficiency, and abnormal noise. If such defects are not detected, a large number of defective products will flow downstream, increasing rework costs and potentially causing equipment failure or safety accidents. Therefore, this invention proposes a chain assembly machine device and its process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] S2, the mechanical sorting mechanism will assemble the complete part of the first inner link assembly assembly, that is, the sleeve with rollers on the outer wall, and send it into the second inner link assembly assembly to intercept the incomplete part, that is, the sleeve without rollers.

[0022] S3, the second inner link assembly works, assembling the remaining inner link plate at the top of the sleeve.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1. The main structure of this invention includes a first inner link assembly, a mechanical sorting mechanism, and a second inner link assembly. The first inner link assembly is used to fit an inner link plate onto the bottom of the sleeve and to fit a roller onto the outer wall of the sleeve. The second inner link assembly is used to press the top of the semi-finished product of the first inner link assembly into the remaining inner link plate to form an inner link. The mechanical sorting mechanism can detect and sort the semi-finished products of the first inner link assembly, capturing and intercepting the semi-finished products without rollers, and sending the semi-finished products with rollers to the second inner link assembly. The assembly of the last inner chain plate significantly reduces the risk of problems in existing chain assembly machines. Before pressing the top of the sleeve into the remaining inner chain plate, the lack of a detection and sorting mechanism can lead to issues. For example, a malfunction in the chain assembly machine might result in the sleeve's outer wall not being pressed into the roller, with its top being pressed into the remaining inner chain plate. During chain transmission, the missing roller causes direct contact between the sleeve and the sprocket teeth, increasing sliding friction, leading to abnormal wear, a sharp drop in transmission efficiency, and abnormal noise. If such defects are not detected, a large number of defective products will flow downstream, increasing rework costs and potentially causing equipment failure or safety accidents.

[0025] 2. The mechanical sorting mechanism of this invention is entirely composed of a mechanical structure. It operates based on the change in diameter at the semi-finished sleeve assembly point of the first inner link assembly component. The transfer mechanism of the mechanical sorting mechanism operates along a predetermined path. Only after the outer wall of the semi-finished sleeve is fitted with rollers, and the sleeve diameter increases, can the transfer mechanism transport the semi-finished product from the unloading point of the first inner link mechanism to the loading point of the second inner link mechanism. No electrical detection components are required, resulting in a simple, stable, and reliable structure. By allowing only sleeves with increased outer diameters (i.e., those fitted with rollers) to enter the next assembly process, assembly defects caused by missing rollers are effectively avoided, improving assembly quality and chain performance, reducing rework risks and safety hazards, and making it suitable for high-efficiency automated production lines.

[0026] 3. The present invention provides a workbench unloading mechanism at the unloading point of the first inner link assembly mechanism. After the transfer mechanism of the mechanical sorting mechanism reaches a certain position according to the predetermined path, the workbench unloading mechanism will perform the unloading operation. If the semi-finished product at the unloading point of the first inner link mechanism is not transferred away by the mechanical sorting component because it is not fitted with rollers, the unloading mechanism will unload the defective product to leave space for the unloading of the first inner link assembly mechanism. The logic of the controller controlling the mechanical sorting component, the workbench unloading mechanism and other components is simple, which facilitates the upgrading and maintenance of the equipment.

The top of the release plate 16 is flush with the top surface of the workbench 2. The third assembly cylinder 110 and the second inner chain plate material box 10 are not flush with the second assembly cylinder 11.

[0050] The specific implementation steps and principles of this invention are as follows:

[0051] Two path planning components set on the side of the workbench 3 sequentially drive the first common seat 18 and the second common seat 40 to move in a U-shaped path. The first chain plate pusher 18 sequentially obtains an inner chain plate from the bottom of the first inner chain plate box 6 and moves laterally. The sleeve pusher 183 obtains a sleeve from the top of the first horizontal T seat 71 of the sleeve box 7. The middle pusher 182 moves the inner chain plate to the position of the first assembly cylinder 8. The first assembly cylinder 8 presses the bottom of the sleeve into the inner chain plate. The first pusher 184 transfers the sleeve and inner chain plate as a whole. The auxiliary pusher 185 captures the sleeve and inner chain plate as a whole and transfers it to the bottom of the second assembly cylinder 8. The roller pusher 186 obtains a roller from the top of the first horizontal T seat 71 at the bottom of the roller box 9. The roller, sleeve, and inner chain plate move simultaneously to the bottom of the second assembly cylinder 8 to complete the action of pressing the roller into the outer wall of the sleeve. The end pusher 188 sends the semi-finished product into the side of the connecting plate 22.

[0052] When the mechanical sorting mechanism is activated, the vertical motor 24 pushes the bottom seat 30 to move along the guide rail 29 via the toggle frame 23 and the horizontal column 28. The two gripping arms 25 gradually approach one of the sleeves on the top of the inner chain plate inside the buffer tank 220. During this process, the horizontal column 28 moves along the inclined surface 34 and the horizontal surface 35 on the side of the U-shaped guide rod 36. The two gripping arms 25 move closer to a set distance. Assuming that the roller is correctly fitted on the outer wall of the sleeve on the side of the buffer tank 220, the two gripping arms 25 will grip the semi-finished product and move it forward a certain distance. When the horizontal column 28 moves to the starting end of 37, the semi-finished product is released. During this period, the micro switch 33 is triggered, and the release cylinder 15 drives the release plate 16 to open, releasing the defective products that have not been transferred.

[0053] When the second common seat 40 makes a loop path movement, the semi-finished product is transported from the clearance groove 187 by the capture pallet 404, the half-stroke push plate 403 transports the semi-finished product to the position of the third assembly cylinder 110, and the second chain plate push plate 402 transports the remaining chain plate to the bottom of the third assembly cylinder 110, finally completing the assembly of the entire inner chain link.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
