Description

Technical Field

[0001] This application relates to the technical field of automatic equipment, and in particular to a linkage stopper. Background Technology

[0002] Stoppers are widely used in automated production lines, assembly equipment, and AGV material handling, mainly for blocking, positioning, and diverting workpieces or materials. Most existing stoppers are pneumatically driven, have a large structural size, occupy internal space, and are difficult to install and use in space-constrained environments; at the same time, pneumatic devices rely on an air source, which cannot meet the application needs in some environments without an air source.

[0003] Meanwhile, existing stoppers typically only allow for independent operation of a single unit, failing to achieve coordinated control between multiple units, thus limiting their application in complex scenarios such as multi-station collaboration and AGV multi-vehicle scheduling. Therefore, existing technologies still have shortcomings in terms of applicability without an air source and multi-unit coordination, requiring improvement. Utility Model Content

[0004] To meet the requirements of environments without air supply and multiple linkages, this application provides a linkage stopper.

[0005] The linkage stopper provided in this application adopts the following technical solution: A linkage stopper includes a stopper assembly. The stopper assembly includes a base for mounting on an AGV or automated equipment. A fixing sleeve is fixed on the base. A stopping pin is disposed within the fixing sleeve and slides vertically within the fixing sleeve. A drive shaft is horizontally disposed within the base. A transmission component for moving the stopping pin is disposed on the drive shaft. Multiple stopper assemblies are spaced apart along the axis of the drive shaft. A connecting shaft is coaxially fixed between any two adjacent drive shafts of the stopper assemblies. The stopper assembly also includes a drive component connected to the drive shaft of one of the stopper assemblies.

[0006] By adopting the above technical solution, by setting a fixed sleeve and a blocking pin on the base, and using a drive shaft and transmission assembly to realize the vertical lifting and lowering of the blocking pin, and then using a connecting shaft to make multiple blocking components move in tandem along the drive shaft, and finally being driven by the drive assembly, multiple blocking devices can work together in an environment without an air source, ensuring that the blocking action is synchronous and reliable, thereby meeting the usage requirements of automatic equipment or AGVs in multi-station or multi-vehicle collaboration.

[0007] Preferably, by setting a fixed sleeve and a blocking pin on the base, and using a drive shaft and transmission assembly to realize the vertical lifting and lowering of the blocking pin, and then using a connecting shaft to make multiple blocking components move in tandem along the drive shaft, and finally being driven uniformly by the drive assembly, multiple blocking devices can work together in an environment without an air source, ensuring that the blocking action is synchronous and reliable, thereby meeting the usage requirements of automatic equipment or AGVs in multi-station or multi-vehicle collaboration.

[0008] By adopting the above technical solution, the transmission component, through the cooperation of the rocker arm, rotating shaft and connecting plate, transforms the rotational motion of the drive shaft into the lifting motion of the blocking pin. The positioning shaft stably transmits the motion process to the blocking pin, thereby ensuring that the blocking pin moves smoothly, is accurately positioned, and can maintain a reliable self-locking state.

[0009] Preferably, the fixing sleeve is provided with a sliding groove, the sliding groove is U-shaped, the lower end of the sliding groove is open, and the positioning shaft slides in the sliding groove in the vertical direction.

[0010] By adopting the above technical solution, the U-shaped sliding groove allows the positioning shaft to slide along a defined trajectory in the vertical direction, which can effectively prevent the blocking pin from shifting laterally during the lifting process, ensuring the stability and accuracy of the blocking action, and improving the reliability of the entire blocking mechanism.

[0011] Preferably, a limiting bolt is also fixed on the base, and the limiting bolt is located on the side of the swing arm away from the blocking pin along the width direction of the base.

[0012] By adopting the above technical solution, the limit bolt can provide an effective limiting effect during the movement of the swing arm, preventing the swing arm from deviating or swinging excessively, thereby improving the stability of the lifting and lowering of the blocking pin and ensuring the durability and safety of the mechanism in long-term operation.

[0013] Preferably, a guide copper sleeve is also fitted onto the upper end of the blocking pin.

[0014] By adopting the above technical solution, the guide copper sleeve can effectively reduce the friction and wear of the blocking pin during the lifting process, improve the guiding accuracy and service life of the blocking pin, and make the blocking action smoother and more reliable.

[0015] Preferably, the drive assembly includes a servo motor, and a mounting bracket for mounting on an AGV or automated equipment is fixed on the servo motor housing. A pulley is coaxially fixed on the output shaft of the servo motor, and a pulley is also coaxially fixed on the drive shaft of the stop assembly closest to the servo motor. A belt is wound around the two pulleys.

[0016] By adopting the above technical solution, the drive component uses a servo motor in conjunction with belt drive, so that the power of the motor output shaft is stably transmitted to the drive shaft of the stopper assembly through the pulley and belt, thereby ensuring the smoothness and response speed of the stopper pin lifting action, and facilitating installation and use on space-constrained equipment or AGVs.

[0017] Preferably, each of the connecting shafts is coaxially fixed with a coupling at both ends, and each coupling is coaxially fixed with the drive shaft of the corresponding side stop assembly.

[0018] By adopting the above technical solution, and by fixing couplings coaxially at both ends of the connecting shaft and connecting them to the corresponding drive shafts, the power transmission between multiple stopper assemblies can be ensured synchronously, enabling multiple sets of stoppers to operate in a coordinated manner, thereby improving the reliability and linkage effect of the system operation.

[0019] Preferably, a position detection component for detecting the position of the blocking pin is provided on the outer side of the blocking component on the side opposite to the driving component.

[0020] By adopting the above technical solution, the position detection component can detect the real-time position of the blocking pin, realize the monitoring and feedback of the blocking status, thereby improving the intelligence level and operational safety of the blocking mechanism.

[0021] Preferably, an indicator plate is fixed on the drive shaft of the stopper assembly on the side opposite to the drive assembly. A protrusion is formed on the indicator plate. The position detection assembly includes two detection probes. When the stop pin is located at the highest point and the lowest point, the protrusion corresponds to the two detection probes respectively.

[0022] By adopting the above technical solution, and through the cooperation of the convex plate and two detection probes, the position of the blocking pin can be accurately detected when it is at its highest and lowest points, thereby achieving accurate judgment of the limit position of the blocking pin, ensuring the reliability of the blocking process and meeting the automatic control requirements of the equipment.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the coordinated design of the drive shaft and the connecting shaft, multiple stopper components can be driven in a unified manner and maintain synchronous operation. Multiple sets of linkage can be achieved without relying on the air source, which is particularly suitable for application in automated equipment or AGV scenarios, improving the applicability and scalability of the device. 2. The transmission assembly, in conjunction with the fixed sleeve, sliding groove, and guide copper sleeve, enables the blocking pin to move up and down stably and smoothly, and has a reliable self-locking function, ensuring the accuracy of blocking positioning and safety during operation, while reducing wear and increasing the service life of the mechanism. 3. The drive component adopts a servo motor and belt drive, and combined with the design of position detection components and indicator plates, it realizes smooth drive and real-time status monitoring of the blocking pin movement, thereby improving the intelligence level of the blocker and the reliability of system operation.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses a linkage stopper.

[0028] See Figures 1-3 The linkage stopper includes a stopper assembly 1, which includes a drive shaft 14. The drive shaft 14 is horizontally arranged, and multiple stopper assemblies 1 are spaced apart along the axis of the drive shaft 14. A connecting shaft 3 is provided between any two adjacent drive shafts 14, and couplings 31 are coaxially fixed at both ends of the connecting shaft 3. Any coupling 31 is coaxially fixed to the corresponding drive shaft 14. A drive assembly 4 is provided on the side of the stopper assembly 1 on one side of the drive shaft 14 that is away from the other stopper assemblies 1, and a position detection assembly 5 is provided on the other side.

[0029] The stopper assembly 1 also includes a base 11, which is used for mounting on AGVs or automated equipment. A drive shaft 14 passes through the base 11 along its own axis and is rotatably connected to the base 11. A fixing sleeve 12 is fixed on the base 11, and a stopping pin 13 is disposed within the fixing sleeve 12. The stopping pin 13 slides vertically against the fixing sleeve 12, and a guide copper sleeve 131 is fitted onto the upper end of the stopping pin 13. A transmission assembly 2 is disposed on the drive shaft 14. The transmission assembly 2 includes a rocker arm, one end of which is fitted onto the drive shaft 14 along its length, and the other end of which is provided with a rotating shaft 22. The axis of the rotating shaft 22 is parallel to the axis of the drive shaft 14. A connecting plate 23 is disposed on the rotating shaft 22, one end of which is rotatably connected to the rotating shaft 22 along its length, and the other end of which is provided with a positioning shaft 24. The axis of the positioning shaft 24 is parallel to the axis of the drive shaft 14, and the other end of the positioning shaft 24 is fixed to the stopping pin 13. The fixed sleeve 12 is provided with a sliding groove 121, which is U-shaped and open at the lower end. The positioning shaft 24 slides vertically within the sliding groove 121. A limit bolt 15 is also fixed on the base 11, located on the side of the swing arm away from the blocking pin 13 along the width direction of the base 11. When the swing plate 21 and the connecting plate 23 are aligned in the length direction, the blocking pin 13 is at its highest point, and at this time, the swing plate 21 and the connecting plate 23 are in a self-locking state.

[0030] The drive assembly 4 includes a servo motor 41. An AGV or automatic equipment is also fixed with a mounting bracket. The housing of the servo motor 41 is fixed on the mounting bracket. A belt 42 pulley is coaxially fixed on the output shaft of the servo motor 41. A belt 42 pulley is also coaxially fixed on the drive shaft 14 of the stop assembly 1 closest to the servo motor 41. A belt 42 is wound around the two belt 42 pulleys.

[0031] An indicator plate 52 is fixed on the drive shaft 14 of the stop assembly 1 on the side opposite to the drive assembly 4. A protrusion plate 53 is formed on the indicator plate 52. The position detection assembly 5 includes two detection probes 51. When the stop pin 13 is located at the highest point and the lowest point respectively, the protrusion plate 53 corresponds to the two detection probes 51 respectively.

[0032] The implementation principle of the linkage stopper in this embodiment is as follows: Workers fix multiple bases 11 and mounting brackets to the locations on the AGV or automated equipment where blocking is required. The output shaft of the servo motor 41 rotates, driving the nearest drive shaft 14 to rotate. This drive shaft 14 drives the connecting shaft 3 via a coupling 31, thereby causing multiple drive shafts 14 and connecting shafts 3 to rotate simultaneously. Any drive shaft 14 drives the corresponding swing plate 21 to rotate, which in turn drives the connecting plate 23 to rotate. The connecting plate 23 drives the positioning shaft 24 to slide downwards along the length of the sliding groove 121, thereby causing the blocking pin 13 to slide downwards vertically. In this way, the servo motor 41 can drive multiple blocking pins 13 to slide downwards simultaneously vertically, achieving the effect of blocking or resetting. The position detection component 5 can detect the position of the blocking pins 13 in real time.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
