Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to fig. 3, it is a schematic structural diagram of a casing loading device for a casing machine according to the present invention. The sleeve loading device for the sleeve machine comprises a machine table 10, a sleeve cutting device 20 arranged on the machine table 10 and a lead conveying device 30 arranged on the machine table 10. It is contemplated that the casing loading apparatus for the casing machine may further include other functional modules, such as a mounting assembly, an electrical connection assembly, a control device for controlling the sequential operations of the casing cutting device 20 and the wire feeding device 30, etc., which are well known to those skilled in the art and will not be described in detail herein.

The machine 10 is used for carrying the casing cutting device 20 and the wire conveying device 30, and other functional modules, such as a spindle module, a tail clamping module, etc., therefore, the structure and shape of the machine 10 should be able to mount the above functional modules, and will not be described in detail herein.

The sleeve cutting device 20 includes a sleeve conveying wheel set 21 disposed on the machine table 10, two sleeve conveying pipes 22 disposed on two sides of the sleeve conveying wheel set 21, a sleeve clamping mechanism 23 disposed in the outlet direction of the sleeve conveying wheel set 21, and a cutting mechanism 24 disposed between the sleeve conveying wheel set 21 and the sleeve clamping mechanism 23. The sleeve conveying wheel set 21 comprises two rollers 211 which abut against each other, and two drivers 212 which respectively drive the two rollers 211 to rotate in opposite directions. The sleeve is sandwiched between two rollers 211 and is driven to advance while the rollers 211 rotate in opposite directions. The driver 212 may be a servo motor, which can output a driving force for a certain time interval under the control of the control device, so as to achieve the purpose of delivering a certain length of casing. The cannula-delivering tube 22 is two straight tubes, which are used to ensure the direction of the cannula during the delivery process, so that the delivered cannula can be accurately inserted into the cannula-holding device 23. The casing gripping mechanism 23 comprises a pushing mechanism 231 and a gripping assembly 232 disposed on the pushing mechanism 231. The pushing mechanism 231 is used to reciprocally push the clamping assembly 232 toward the wire feeding device 30 or pull it back from the wire feeding device 30 to the initial position. The pushing mechanism 231 is a conventional one, and may include a cylinder driver, a slide assembly disposed between the clamping assembly 232 and the machine table 10, and the like. The cylinder driver drives the clamping assembly 232 to reciprocate under the control of the control device. The clamping assembly 232 includes a lower clamping platform 233 disposed on the pushing mechanism 231, an upper clamping platform 234 disposed opposite to the lower clamping platform 233, at least one resilient member 235 interposed between the upper and

lower clamping platforms

233, 234, and an abutting mechanism 236 abutting against the upper clamping platform 234 and driving the upper clamping platform 234 to clamp the lower clamping platform 233. The lower clamping stage 233 has a planar structure. A sleeve clamp groove 237 is arranged on the upper clamp table 234. The cross-sectional profile of the sleeve clamping groove 237 is arc-shaped, and the arch height of the arc is larger than the radius of the sleeve, so that when the upper and

lower clamping platforms

233, 234 are clamped, the upper and

lower clamping platforms

233, 234 do not crush the sleeve, thereby preventing the lead wire from being inserted into the sleeve. The resilient member 235 is disposed between the upper and

lower clamping platforms

233 and 234, and pushes the upper and

lower clamping platforms

233 and 234 apart to insert the casing when the resilient member 235 is not subjected to an external pressure. The return elastic member 235 may have two springs. The propping mechanism 236 can be a cylinder having a propping head reciprocating under the control of the control module to open and close the upper and

lower clamping platforms

233, 234. Specifically, when the cannula conveying wheel set 21 pushes the cannula into the cannula clamping groove 237 of the upper and lower clamping tables 233, 234, the elastic force of the resilient member 235 overcome by the abutting mechanism 236 clamps the cannula between the upper and lower clamping tables 233, 234. The clamping assembly 232 further includes two guide posts 238 disposed on the upper and lower clamping tables 233, 234. The guide post 238 is fixed on the lower clamping table 233, and the upper clamping table 234 is slidably disposed on the guide post 238, so that the upper clamping table 234 can slide more stably and accurately. The cutting mechanism 24 includes a blade 241 attached to the end surfaces of the upper and lower clamping stages 233, 234, and a driving mechanism 242 for driving the blade 241 to reciprocate. The blade 241 is attached to the end surfaces of the upper and lower clamping tables 233 and 234 to form a shearing effect with the upper and lower clamping tables 233 and 234, so that the effect of scissors can be achieved by using only one blade 241, and the size of the whole device can be reduced. The drive mechanism 242 may also be a pneumatic cylinder that reciprocates under the control of the control module to sever the cannula. Meanwhile, the driving mechanism 242 reciprocates twice at a certain time interval to cut two sections of the cannula. When the cutting of the two lengths of casing is completed, the pushing mechanism 231 pushes the clamping assembly 232 towards the wire feeding device 30 to insert the wire into the casing.

The wire feeding device 30 includes a group of wire feeding pipes 31, a wire feeding wheel set 32 disposed in the wire outgoing direction of the wire feeding pipes 31, and a wire clamping mechanism 33 disposed in the wire outgoing direction of the wire feeding pipes 31. One set of the wire feeding tubes 31 has two wire feeding tubes to realize the feeding direction of the wire. The central axis of the guidewire delivery tube 31 is parallel to the central axis of the cannula delivery tube 22. The pushing direction of the pushing mechanism 231 is perpendicular to the arrangement direction of the cannula conveying pipe 22 and the guide wire conveying pipe 31. The structure of the wire conveying wheel set 32 is the same as that of the sleeve conveying wheel set 21, and the difference is only that the diameters of the grooves for clamping the wires are different, so the description is omitted here. The thread trap mechanism 33 is positioned between the wire transport tube 31 and the clamp assembly 232 when the cannula clamp groove 237 is aligned with the wire transport tube 31. When the clamping assembly 232 is pushed to the outgoing direction of the wire conveying device 30, the central axis of the sleeve clamping groove 237 coincides with the central axis of the wire conveying pipe 31, and when the sleeve clamping groove 237 is aligned with the wire conveying pipe 31, the wire conveying pipe 31 sends out a wire to penetrate the wire into two sections of the sleeves.

In operation, the upper and lower clamping tables 233, 234 are opened by the resilient member 235, and then the ferrule is inserted into the ferrule holding groove 237, during the insertion process, the ferrule is cut twice by the blade 241 at a certain interval, thereby forming two sections of ferrules, and then the abutting mechanism 236 abuts against the upper clamping table 234 to clamp the two sections of ferrules. The pushing mechanism 231 then pushes the clamping member 232 toward the wire feeding device 30 such that the central axis of the sleeve clamping groove 237 coincides with the central axis of the wire feeding tube 31. The wire is then fed out by the wire feeding wheel set 32 and inserted into the sleeve. When the wire is pulled out to be wound on the magnetic core, the abutting mechanism 236 is disengaged from the upper clamping table 234 for the first time to pull out one sleeve by the wire, and after one sleeve is pulled out, the abutting mechanism 236 abuts against the upper clamping table 234 again to clamp another sleeve so as to prevent the other sleeve from being pulled out. When the wire is completely wound around the core, the abutting mechanism 236 is disengaged from the upper clamping table 234 for the second time to allow the wire to pull out the second sleeve to wind the second sleeve around the core.

Compared with the prior art, the utility model provides a sleeve pipe loading equipment for jacketing machine is through setting up sleeve pipe cutting device 20, specifically, sleeve pipe cutting device 20 has sleeve pipe fixture 23 and cutting mechanism 24, cutting mechanism 24 can be two times sleeve pipes of certain interval cutting to form two sections sleeve pipes that have certain length, sleeve pipe fixture 23 has a push mechanism 231 and a centre gripping subassembly 232.
