[0034] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0035] First, combine Figures 1 to 3 A servo cover screwing device according to an embodiment of the utility model is described, which is used to screw a cover 7 onto an object and has a wide range of application scenarios.

[0036] like Figures 1 to 3 As shown, a servo capping device according to an embodiment of the utility model comprises a servo driving module, a transmission module, an elastic clamp 3 and a material pushing mechanism.

[0037] Specifically, if Figure 1 , 3 As shown, the servo drive module is used to provide a driving force for rotation. The servo drive module includes: a servo motor 11 and a reducer 12, the input end of the reducer 12 is connected to the output end of the servo motor 11, and the output end of the reducer 12 is connected to the input end of the transmission module. Through the setting of the servo motor 11, the torque of the cover 7 rotating on the object can be adjusted.

[0038] Further, if Figure 1 , 3 As shown, the servo drive module includes: a mounting plate 13, which is connected to the reducer 12 and is used to be fixed to an external moving mechanism.

[0039] Specifically, if Figure 1~2 As shown, the transmission module is connected to the servo drive module to transmit the power generated by the servo drive module. The transmission module includes: a connecting frame 21, a spline shaft 22, a spline nut 23, a guide sleeve 24 and a spring 25. The connecting frame 21 is connected to the output end of the servo drive module; the top of the spline shaft 22 is connected to the connecting frame 21; the spline nut 23 is axially slidably sleeved on the spline shaft 22; the guide sleeve 24 is connected to the top of the spline nut 23 and sleeved on the bottom of the connecting frame 21; the top of the spring 25 is connected to the connection, and the bottom of the spring 25 is connected to the guide sleeve 24. Through the setting of the spring 25, when the cover 7 contacts an object, the reaction force can be transmitted to the spline nut 23 and the guide sleeve 24, so that the guide sleeve 24 compresses the spring 25, which plays a certain buffering role and ensures the effect of screwing the cover.

[0040] Further, if Figure 1~2As shown, a limiting protrusion 211 is provided on the connecting frame 21 , and the limiting protrusion 211 is used to position the guide sleeve 24 .

[0041] Specifically, if Figure 1~2 As shown, the elastic clamp 3 is connected to the transmission module, and a plurality of latch teeth are arranged on the inner wall of the elastic clamp 3 for clamping the external cover 7 and rotating with the action of the transmission module to screw the cover 7 onto the external object.

[0042] Specifically, if Figures 1 to 3 As shown, the push mechanism is connected to the elastic chuck 3, and when there is no object in the external capping processing position, the cover 7 on the elastic chuck 3 is pushed out. The push mechanism includes: a housing 41, a piston cavity, a piston push rod 43, a first air inlet 44 and a second air inlet 45. The top of the housing 41 is connected to the output end of the transmission module; the piston cavity is opened inside the housing 41; the piston push rod 43 is arranged in the piston cavity, and one end of the piston push rod 43 passes through the piston cavity, and the piston push rod 43 divides the piston cavity into a rod cavity 422 and a rodless cavity 421; the first air inlet 44 is opened on the housing 41 and communicated with the rodless cavity 421; the second air inlet 45 is opened on the housing 41 and communicated with the rod cavity 422. By injecting gas into the first air inlet 44, the piston push rod 43 can move downward to push out the cover 7 clamped by the elastic chuck 3, and by injecting air into the second air inlet 45, the piston push rod 43 can move upward to reset.

[0043] Further, if Figures 1 to 3 As shown, the elastic clamp 3 is arranged at the bottom of the housing 41, and a limiting sleeve 5 is arranged between the elastic clamp 3 and the housing 41. The limiting sleeve 5 is provided with a clearance hole, which is used to provide a space for the piston push rod 43 to move forward and backward. The limiting sleeve 5 is used to limit the position of the elastic clamp 3 clamping the cover 7.

[0044] Further, if Figures 1 to 3 As shown, a servo capping device of an embodiment of the utility model further comprises: a coupling 61 and a rotary joint 62. The input end of the coupling 61 is connected to the servo drive module; the core shaft 621 of the rotary joint 62 is connected to the output end of the coupling 61 and the input end of the transmission module, and two inlets 623 are provided on the housing 622 of the rotary joint 62, and two outlets 624 are provided on the core shaft 621 of the rotary joint 62. The two inlets 623 are respectively connected to the two outlets 624, and the two outlets 624 are respectively connected to the first air inlet 44 and the second air inlet 45. Through the setting of the rotary joint 62, the air path transportation can be made more convenient, and the problem of air path winding inconvenience can be prevented.

[0045] Working principle:

[0046] First, the mounting plate 13 is connected to the external moving mechanism, and then the moving mechanism drives the screw capping device to move to the cap 7 station, and the cap 7 is clamped by the elastic deformation of the elastic chuck 3, and then moved to the screw capping processing position, and the external moving mechanism drives the elastic chuck 3 to clamp the cap 7 close to the object to be screwed on. After contacting the object, the servo motor 11 is pneumatically driven to drive the coupling 61, the core shaft 621 of the rotary joint 62, the transmission module, and the elastic chuck 3 to rotate, and the bottle cap is screwed on the object.

[0047] When there is no object to be screwed on at the screw-on processing position, in the gap where the elastic chuck 3 grabs a new cover 7, gas is injected through one of the inlets 623, and the gas is transferred to the first air inlet 44 through the outlet 624 connected thereto and enters into the rodless chamber 421, so that the piston push rod 43 moves downward to push off the cover 7 of the elastic chuck 3, and then gas is injected through another inlet 623, and the gas is transferred to the second air inlet 45 through the outlet 624 connected thereto and enters into the rod chamber 422, so that the piston push rod 43 moves upward and resets, and the cover 7 can be grabbed again.

[0048] Above, refer to Figures 1 to 3 A servo capping device according to an embodiment of the utility model is described, in which a pushing mechanism is arranged on the elastic clamp 3. When there is a shortage of bottles in the capping processing position, the cap 7 of the elastic clamp 3 is pushed off in the gap when the elastic clamp 3 grabs the new cap 7, so that the elastic clamp 3 grabs the new cap 7 without collision, thereby ensuring that the grip is intact.
