DETAILED DESCRIPTION

[0036] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] like Figures 1 to 4As shown, a circulating tooling screw locking machine includes a workbench 1, an annular conveyor line 2, a conveying fixture 3, a loading station 4, a detection device 5, a screw locking device 6 and a unloading device 7. Among them, the annular conveyor line 2 is arranged on the workbench 1. Several conveying fixtures 3 are connected to the annular conveyor line 2 at intervals and move in a circular cycle on the workbench 1 through the annular conveyor line 2; the loading station 4, the detection device 5, the screw locking device 6 and the unloading device 7 are sequentially installed on the workbench 1 around the annular conveyor line 2; when the loading station 4 corresponds to the position of one conveying fixture 3, the detection device 5, the screw locking device 6 and the unloading device 7 each correspond to one conveying fixture 3. When the loading station 4 is loading, other stations can also complete the corresponding work at the same time, shortening the production time and significantly improving the production efficiency. Among them, the detection device 5 is a camera module or a detection sensor, which is used to detect the position of the workpiece to be screwed to determine whether the screw needs to be screwed.

[0038] The circulating tooling screw locking machine is provided with a ring conveyor line 2, a conveying fixture 3, a loading station 4, a detection device 5, a screw locking device 6 and a material unloading device 7 on a workbench 1. The conveying fixture 3 is moved in a ring-shaped cycle on the workbench 1 by the ring conveyor line 2. The material is first loaded at the loading station 4, and the workpiece to be screwed is placed on the conveying fixture 3. Then, the detection device 5 is used for detection to detect the position of the workpiece to be screwed to determine whether the screw needs to be screwed. If it meets the requirements, the screw needs to be screwed, and the screw locking device 6 screws the workpiece to be screwed, and unloads it at the material unloading device 7; if it does not meet the requirements, the screw locking device 6 and the material unloading device 7 do not screw the workpiece to be screwed, and the ring conveyor line 2 is re-conveyed to the loading station 4 for re-assembly and loading. The circulating tooling screw locking machine is arranged in this way, so that the circulating tooling screw locking machine has the characteristics of high efficiency, optimized space utilization, and can solve the problem of stacking. High efficiency is reflected in: the circular conveying function of the circular conveyor line 2 enables the workpiece to be screwed continuously, significantly improving production efficiency; compared with traditional linear conveying or fixed-point processing methods, it greatly reduces downtime waiting time and improves equipment utilization. Optimized space utilization is reflected in: the compact design of the circular conveyor line 2 and its combination with other structures make the entire equipment occupy a smaller area and optimize space utilization, which is of great significance for the spatial layout of the production site and saving production costs. The solution to the problem of stacking is specifically manifested in that through the reasonable design of the circular conveyor line 2 and the combined control strategy of the circular conveyor line 2, the conveying fixture 3, the loading station 4, the detection device 5, the screw locking device 6 and the unloading device 7, the stacking phenomenon that may occur in traditional equipment is effectively avoided. The continuous flow of workpieces on the circular conveyor line 2 ensures the smooth progress of the production process and reduces the risk of production interruption.

[0039] In this embodiment, the annular conveyor line 2 includes a servo motor 21, a transmission mechanism 22, a main sprocket 23, a secondary sprocket 24, a chain 25 and an annular slide rail 26; the main sprocket 23 and the secondary sprocket 24 are rotatably connected to the two ends of the workbench 1 respectively; the chain 25 is appropriately mounted on the main sprocket 23 and the secondary sprocket 24; the servo motor 21 is connected to the main sprocket 23 through the transmission mechanism 22; the transmission mechanism 22 is an existing conventional structure and is not described in detail. The annular slide rail 26 is installed on the workbench 1 around the chain 25; the conveying fixture 3 can be slidably connected to the annular slide rail 26 and connected to the chain 25. The servo motor 21 drives the main sprocket 23 through the transmission mechanism 22. The main sprocket 23 rotates, driving the chain 25 and the secondary sprocket 24 to rotate. Under the action of the rotation of the chain 25, the conveying fixture 3 can rotate synchronously with the chain 25 on the annular slide rail 26, which is stable and reliable, and can effectively avoid the deviation or shaking of the conveying fixture 3 during the movement, thereby ensuring the stability and accuracy of the operation of the circulating tooling screw locking machine. The circular conveyor line 2 designed in this way can make the circulating tooling screw locking machine have the characteristics of high efficiency, optimized space utilization, and solving the problem of stacking in the application of the entire equipment.

[0040] In this embodiment, the conveying fixture 3 includes a movable slide 31, a workpiece fixture 32 and a connecting member 33; the movable slide 31 can be slidably connected to the annular slide rail 26; the workpiece fixture 32 is installed on the movable slide 31; and the movable slide 31 is connected to the chain 25 through the connecting member 33.

The push rod 42 is pushed by the push cylinder 41 to make the rotating shaft 44 rotate on the locking rod 45, so that the locking rod 45 swings. Through control, when the locking rod 45 is adapted and clamped with the locking groove 34, the annular conveyor line 2 stops conveying, which is convenient for placing the workpiece to be assembled on the conveying fixture 3, improves the stability of placing the workpiece to be assembled, and realizes the rapid and accurate positioning of the conveying fixture 3. The feeding effect is good. After the feeding is completed, under the push of the push cylinder 41, the locking rod 45 is away from the locking groove 34, achieving a good unlocking effect, and the annular conveyor line 2 resumes conveying.

The movable sliding mechanism 72 is used to adjust the workpiece clamping assembly 73 to move between the annular conveyor line 2 and the unloading track 74, and then the workpiece clamping assembly 73 clamps the workpiece with the screws locked, and under the action of the movable sliding mechanism 72, it is transported to the unloading track 74, so as to achieve a good unloading effect and high production efficiency.
