Description

Technical Field

[0001] The utility model relates to the technical field of precision parts processing, in particular to a buckle assembly device capable of self-adapting to part height. Background Art

[0002] Connectors are a type of component that our electronic engineering technicians often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. Generally, connectors are assembled from multiple parts. The components of the connector are large and small. In the assembly flow channel station, the heights of the two parts will be different. It is necessary to set flow channel stations of different heights, which is relatively cumbersome. In order to improve the assembly efficiency, high-speed reciprocating servo motors are often used, and there are higher requirements for the inertia of the servo motor when it stops.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model installs a pressure sensor under the groove wheel guide mechanism, and the servo motor controls the rotation of the reciprocating wheel. The rotation of the connecting piece drives the cam follower A to move. The guide column fixed with the cam follower A slides up and down along the longitudinal linear guide rail, and the longitudinal linear guide rail slides left and right along the transverse linear guide rail, so that the guide column follows the cam follower B to move along the limited track of the limit groove to transport the parts to be assembled to the specified position. Since the assembled parts are different in height, there will be height inconsistency in the horizontal direction at the assembly station. The pressure sensor is embedded in the nozzle fixing frame, and the pressure value of the buckle nozzle is set when assembling parts of different heights. The pressure generated after the buckle nozzle contacts the surface of the part is fed back by the pressure sensor to the digital pressure sensor for display. When the value reaches the set value, the digital pressure sensor sends a signal to control the servo motor to stop running. At this time, the parts installed on the assembly station are assembled, so that the assembly device can adapt to different part heights and improve the applicability of the device.

[0012] 2. The utility model installs a damping reducer on one side of the reciprocating wheel. When assembling parts, in order to improve the assembly efficiency, the snap-on suction nozzle is often required to perform high-speed reciprocating motion. In this way, the reciprocating wheel has a large inertia. The damping reducer is installed on one side of the reciprocating wheel. When the part assembly is about to reach the set end point, the digital pressure sensor sends a signal, the damping reducer works, and cooperates with the servo motor to reduce the speed of the reciprocating wheel until it stops, thereby solving the problem of large inertia and improving the precision of part assembly.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5As shown, the utility model provides a snap-on assembly device with adaptive part height, comprising a mounting seat 1, a component mounting bracket 2, a groove wheel guide mechanism 3, a front block shell 4, a limiting groove 5, a digital pressure sensor 6, a sensor bracket 7, a servo motor 8, a servo motor bracket 9, a snap-on suction nozzle 10 and a vacuum generator 11; a component mounting bracket 2 is fixed in front of the mounting seat 1, a groove wheel guide mechanism 3 is fixed at the upper center of the component mounting bracket 2, a front block shell 4 is fixed at the front end of the component mounting bracket 2, a limiting groove 5 is provided on the front block shell 4, a sensor bracket 7 is fixed above the front block shell 4, a digital pressure sensor 6 is fixed on the sensor bracket 7, a servo motor bracket 9 is fixed on the rear surface of the component mounting bracket 2, a servo motor 8 is fixed on the servo motor bracket 9, a vacuum generator 11 is fixed on the side of the servo motor bracket 9 away from the servo motor, and a snap-on suction nozzle 10 is connected to the lower end of the groove wheel guide mechanism 3.

[0021] refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 A nozzle fixing frame 310 is installed at the lower end of the guide column 308, and a pressure sensor 311 is embedded in the nozzle fixing frame 310. The pressure sensor 311 is electrically connected to the top digital pressure sensor 6.

[0022] By installing a pressure sensor 311 below the groove wheel guide mechanism 3, the servo motor 8 controls the reciprocating wheel 301 to rotate, and the connecting piece 302 rotates to drive the cam follower A303 to move. The guide column 308 fixed to the cam follower A303 slides up and down along the longitudinal linear guide 306, and the longitudinal linear guide 306 slides left and right along the transverse linear guide 304, so that the guide column 308 follows the cam follower B309 to move along the limited track of the limit groove 5 to transport the parts to be assembled to the specified position. Due to the difference in height of the assembled parts, there will be height inconsistency in the horizontal direction at the assembly station. The pressure sensor 311 is embedded in the nozzle fixing frame 310 to set the pressure value of the buckle suction nozzle 10 when the parts are assembled. The pressure generated after the buckle suction nozzle 10 contacts the surface of the part is fed back by the pressure sensor 311 to the digital pressure sensor 6 for display. When the value reaches the set value, the digital pressure sensor 6 sends a signal to control the servo motor 8 to stop running. At this time, the parts installed on the assembly station are assembled, so that the assembly device can adapt to different part heights and improve the applicability of the device.

[0023] refer to Figure 2 A damping reducer 312 is installed at one end of the reciprocating wheel 301. The damping reducer 312 is fixed on the rear surface of the component mounting bracket 2. The damping reducer 312 is electrically connected to the digital pressure sensor 6.

[0024] By installing a damping reducer 312 on one side of the reciprocating wheel 301, in order to improve the assembly efficiency when assembling parts, the snap-on suction nozzle 10 is often required to perform high-speed reciprocating motion. In this way, the reciprocating wheel 301 has a large inertia. The damping reducer 312 is installed on one side of the reciprocating wheel 301. When the part assembly is about to reach the set end point, the digital pressure sensor 6 sends a signal, and the damping reducer 312 works, cooperating with the servo motor 8 to reduce the speed of the reciprocating wheel 301 until it stops, thereby solving the problem of large inertia and improving the precision of part assembly.

[0025] How to use

[0026] The working principle and use process of the utility model are as follows: the processed parts are placed in the work station, the vacuum generator 11 works to control the snap nozzle 10 to suck the parts, the servo motor 8 starts to control the reciprocating wheel 301 to rotate, and drives the cam follower A303 to move in the connecting piece 302, so that the guide column 308 connected to the cam follower A303 is lifted up along the longitudinal linear guide 306, and the cam follower B309 moves along the limit groove 5. As the rotation angle of the reciprocating wheel 301 increases, the longitudinal linear guide 306 slides to the left along the transverse linear guide 304. When the set end point of the part assembly is about to be reached, the pressure generated by the snap nozzle 10 after contacting the surface of the part is fed back to the digital pressure sensor 6 by the pressure sensor 311 for display. When the value reaches the set value, the digital pressure sensor 6 sends a signal to control the servo motor 8 to stop running, and the damping reducer 312 works to cooperate with the servo motor 8 to reduce the speed of the reciprocating wheel 301 until it stops, completing the part assembly, and then reversely start the servo motor 8 to send the snap nozzle 10 back to the starting position to complete a cycle.
