Description

Technical Field

[0001] The present invention relates to the technical field of chain assembly, in particular to an assembly machine device for chain assembly and a process thereof. Background Art

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

[0003] In the prior art, the chain assembly machine lacks a detection and sorting mechanism before pressing the top of the sleeve into the remaining inner link plate. The chain assembly machine may malfunction, resulting in the outer wall of the sleeve not being pressed into the roller, and its top being pressed into the remaining inner link plate. During chain transmission, due to the missing roller, the sleeve is in direct contact with the sprocket teeth, and the sliding friction is aggravated, resulting in abnormal wear, a sudden drop in transmission efficiency and abnormal noise; secondly, the rigid overload of the chain link may cause local deformation or even breakage, threatening the safety of the transmission system; in addition, the rollerless chain link is prone to stress concentration during high-speed movement, shortening the overall life of the chain. What is more serious is that if such defects are not detected, a large number of defective products will flow into the downstream, increasing the rework cost and possibly causing equipment failure or safety accidents, seriously affecting production reliability. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that the chain assembly machine in the prior art lacks a detection and sorting mechanism before pressing the top of the sleeve into the remaining inner link plate.

[0022] S3, the second inner link assembly assembly works, and the remaining inner link plates are assembled on top of the sleeve.

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

[0024] 1. The main structure of the present invention includes a first inner link assembly component, a mechanical sorting mechanism and a second inner link assembly component. The first inner link assembly component is used to sleeve the inner link plate on the bottom of the sleeve and sleeve the roller on the outer wall of the sleeve. The second inner link assembly component is used to press the top of the semi-finished product of the first inner link assembly component 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 component, capture and intercept the semi-finished products that are not sleeved with rollers, and send the semi-finished products that are sleeved with rollers to the second inner link assembly component. The assembly of the last inner link plate is greatly reduced. In the existing technology, the chain assembly machine lacks a detection and sorting mechanism before pressing the top of the sleeve into the remaining inner link plate. The chain assembly machine may malfunction, resulting in the outer wall of the sleeve not being pressed into the roller, and its top being pressed into the remaining inner link plate. During chain transmission, due to the missing roller, the sleeve is in direct contact with the sprocket teeth, and the sliding friction is aggravated, resulting in abnormal wear, a sudden drop in transmission efficiency and abnormal noise. If such defects are not detected, a large number of defective products will flow into the downstream, increasing the cost of rework and the possibility of equipment failure or safety accidents.

[0025] 2. The mechanical sorting mechanism of the present invention is entirely mechanical. It operates based on the diameter change of the semi-finished sleeve at the point where the first inner link assembly is assembled. The transfer mechanism of the mechanical sorting mechanism operates according to a predetermined path. Once the outer wall of the semi-finished sleeve is fitted with rollers and the sleeve diameter increases, the transfer mechanism can then 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., sleeves fitted with rollers) to enter the next assembly step, assembly defects caused by missing rollers are effectively avoided, improving assembly quality and chain performance, reducing the risk of rework and safety hazards, and making the system suitable for efficient automated production lines.

[0026] 3. The present invention is provided with a workbench unloading mechanism for controlling the unloading of the workbench at the unloading position of the first inner link assembly mechanism. After the transfer mechanism of the mechanical sorting mechanism works according to the predetermined path and reaches a certain position, the workbench unloading mechanism will perform the unloading operation. If the semi-finished product at the unloading position 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 products to leave space for the unloading of the first inner link assembly mechanism. The logic of the controller for controlling the mechanical sorting component, the workbench unloading mechanism and other components is simple, which facilitates upgrading and maintenance of the equipment.

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

[0051] The two path planning components arranged on the side of the workbench 3 drive the first common seat 18 and the second common seat 40 to move in a U-shaped path in turn, and the first chain plate push plate 18 obtains an inner chain plate from the bottom of the first inner chain plate material box 6 in turn and moves horizontally, and the sleeve push plate 183 obtains the sleeve from the top of the first horizontal T seat 71 of the sleeve material box 7, and the intermediate push plate 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 interior of the inner chain plate, and the first push plate 184 transfers the sleeve and inner chain plate as a whole. The auxiliary push plate 185 captures the sleeve and inner chain plate as a whole and transfers them to the bottom of the second assembly cylinder 8, and the roller push plate 186 obtains the roller from the top of the first horizontal T seat 71 at the bottom of the roller material box 9. The roller, sleeve, and inner chain plate move to the bottom of the second assembly cylinder 8 at the same time, completing the action of pressing the roller into the outer wall of the sleeve, and the end push plate 188 delivers the semi-finished product to the side of the connecting plate 22;

[0052] When the mechanical sorting mechanism is in operation, the vertical motor 24 pushes the bottom seat 30 to move along the guide rail 29 through the toggle frame 23 and the horizontal column 28, and the two clamping arms 25 gradually approach one of the sleeves on the top of the inner chain plate inside the cache slot 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, and the two clamping arms 25 move close to the set distance. Assuming that the rollers are correctly installed on the outer wall of the sleeve on the side of the cache slot 220 at this time, the two clamping arms 25 will clamp the semi-finished product and move it forward a certain distance. When the horizontal column 28 moves to the starting end 37, the semi-finished product will be 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 moves in a circular path, the semi-finished product is transported from the avoidance groove 187 by capturing the 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 plates to the bottom of the third assembly cylinder 110, finally completing the assembly of the entire inner chain link.
