In the present embodiment, referring to fig. 4, the carrying driver 20 is composed of two cylinders, including a lifting cylinder and a translation cylinder, wherein the translation cylinder is disposed on the lifting cylinder; and the relative motion between the first clamp body 21-1 and the second clamp body 21-2 is realized through a clamping finger cylinder which is fixed on a translation cylinder, so that the first clamp body 21-1 and the second clamp body 21-2 are driven by the clamping finger cylinder to make corresponding movement through the lifting movement of the lifting cylinder and the translation movement of the translation cylinder, so as to smoothly clamp the component 300 on the feeding table 10.
The component conveying mechanism conveys the component 300 on the feeding table 10 to the automatic assembly mechanism, specifically, the automatic assembly mechanism comprises an assembly table 30 and a screw locker 31, wherein two ends of the assembly table 30 are respectively provided with a front end limiting part 30-1 and a tail end limiting part 30-2, the front end limiting part 30-1 and the tail end limiting part 30-2 are of U-shaped structures and have opposite openings, and the front end limiting part 30-1, the assembly table 30 and the tail end limiting part 30-2 jointly form a containing cavity for positioning the component 300; the accommodating cavity is positioned below the first clamp body 21-1 and the second clamp body 21-2, so that after the first clamp body 21-1 and the second clamp body 21-2 clamp the assembly 300, the assembly 300 can be placed in the accommodating cavity under the matching driving of the carrying driver 20 and the clamping finger air cylinder; the cavity is mainly used to ensure the stability and positioning of the assembly 300, and to provide better assurance for the subsequent assembly of the screws.
In the embodiment, referring to fig. 5, because the tail end limiting portion 30-2 is disposed on the assembly table 30, in order to match the structure therein, a clearance gap 21-1E corresponding to the tail end limiting portion 30-2 is disposed in the tail end clamping groove 21-1B of the first clamp body 21-1, and similarly, a clearance gap is also disposed on the second clamp body 21-2, when the two clamp bodies are combined, the two clearance gaps are matched to form clearance for the tail end limiting portion 30-2.
Referring to fig. 6-7, the screw locking device 31 mainly acts on the second screw 200 (long screw), the screw locking device 31 is disposed above the cavity and can move up and down, and the screw locking device 31 has a magnetic locking head 31-1, the locking head 31-1 is adapted to the second screw, that is, the locking head 31-1 can act on the second screw 200, the locking operation of the second screw and the first screw is realized by using the locking head 31-1, the locking head 31-1 has magnetism so as to ensure the stability of the connection between the second screw and the locking head 31-1, and the falling of the second screw 200 is avoided by means of magnetic attraction.
In this embodiment, the up-and-down movement of the screw locking device 31 is realized by a vertical driver 32, where the vertical driver 32 may be a linear driving device such as an air cylinder, a linear motor or an electric cylinder, and the screw locking device 31 is fixedly disposed on an output shaft of the vertical driver 32.
Optionally, the automatic assembly mechanism further includes a support plate 33, the above-described vertical driver 32 is fixed on the support plate 33, and the support plate 33 is utilized to form a stable and effective support, so as to facilitate automatic operation of the vertical driver 32 and the screw locker 31;
meanwhile, considering that the output of the vertical driver 32 is often accompanied by vibration, in order to ensure the stability of the screw locking device 31 in the up-and-down moving process, a vertical sliding rail 34-1 and a first sliding seat 34-2 capable of sliding on the sliding rail 34-1 are further arranged on the support plate 33, a switching block 34-3 is fixed on the first sliding seat 34-2, the output end of the vertical driver 32 is fixed with the switching block 34-3, and the screw locking device 31 is fixed with the switching block 34-3; by means of the switching, the screw locking device 31 is not directly fixed with the output shaft of the vertical driver 32 to reduce the transmission of the vibration frequency, and simultaneously, the stability of the screw locking device 31 in the up-and-down sliding process is ensured by the matching of the slide rail and the slide seat,
optionally, a second sliding seat 34-4 is further provided on the sliding rail 34-1, where the second sliding seat 34-4 is spaced from the first sliding seat 34-2 and located below the first sliding seat 34-2, and a buffer block 34-5 is provided on the second sliding seat 34-4, and the buffer block 34-5 is elastically connected to the adapting block 34-3 through an elastic member 34-6; while the locking head 31-1 of the screw locker 31 extends downward and passes through the buffer block 34-5.
By means of the elastic connection between the buffer block 34-5 and the adapter block 34-3, the buffer block 34-5 directly acts on and abuts against the component 300 after the screw locking device 31 descends, so that the screw locking device 31 can further stabilize the component 300 on the assembly table 30 during assembly.
Optionally, the elastic member 34-6 is a spring.
In this embodiment, referring to fig. 6, the mounting table 30 and the supporting plate 33 are both movable in the horizontal plane, because there are five mounting holes in the assembly 300 at different positions, and in order to ensure that the screws can be quickly and stably mounted in the five mounting holes, the supporting plate 33 and the mounting table 30 need to be adjusted and moved to ensure the processing precision, so as to complete the positioning processing.
Because the assembly table 30 provided by the present embodiment is movable, when the first clamp 21-1 and the second clamp 21-2 in the component conveying mechanism clamp the component 300 for conveying, the assembly table 30 can move to a position right below the first clamp 21-1 and the second clamp 21-2, so that the first clamp 21-1 and the second clamp 21-2 can be quickly and stably placed in the accommodating cavity on the assembly table 30 after clamping the component 300 on the feeding table 10.
Considering that the assembly table 30 has a plurality of position points, in order to ensure the moving precision and the position precision of the assembly table 30, the ball screw module is adopted to control the movement of the assembly table, so that the high-precision positioning of five mounting holes of the assembly is realized, and the smooth screw installation is ensured.
The second screw 200 is fed by a second screw feeding mechanism, so that the second screw 200 can be magnetically attracted to the locking head 31-1 of the screw locker 31.
