Description

Conveying mechanism with clamp overturning function for communication wire core wire treatment

Technical Field

The invention relates to a conveying mechanism with a clamp overturning function for processing a communication wire core wire.

Background

With the rapid development and rapid popularization of high-speed data transmission technology and 5G and other network communication technologies, the demand for communication wires is increasing.

The existing wire for high-speed network communication generally comprises a wire core, an insulating adhesive layer, an aluminum foil layer, a braided layer (copper foil) and a plastic protective sleeve (also called an outer cover) from inside to outside, and the end of the wire can be assembled with various connecting terminals and welded to a PCB (printed circuit board) after two sets of treatment processes are carried out on the end of the wire in actual use. The first treatment process is called wire pretreatment in the industry and mainly comprises the steps of peeling off the outer cover, turning and cutting the braided layer, pasting copper foil and wrapping copper foil. At present, corresponding automatic production equipment is arranged in the industry to complete the procedures. The communication wire is processed by the first set of processing technology to form a front-end multi-section core wire processing section of the wire section extending out of the coating outer cover (the number of the core wires coated in the outer cover is determined by the design requirement).

The second set of processing technology is used for carrying the first set of processing technology, which is called core wire processing in the industry and mainly comprises the procedures of port pre-cutting, aluminum foil removing, insulating glue removing and fine cutting. Compared with the first set of treatment process, the treatment process has higher requirements. The port is precut, namely the port of the wire core is cut off tidily, and the front ends of the wire cores are often uneven, so the wire cores are cut neatly after finishing. And the process of removing the aluminum foil in the refinement is divided into the processes of laser aluminum foil, ring cutting and pulling out the aluminum foil, the next step after pulling out the aluminum foil is to adopt laser ring cutting to cut the insulating adhesive layer on the surface of the core wire, then pull out the insulating adhesive layer, and finally carry out fine cutting and trimming on the front end of the core wire according to the position requirement of a welding point with the PCB.

In practical operation, for a kind of production process which needs to weld core wires on two sides of a PCB and has a fall in the welding position of the core wires, the processing size requirements of the core wires on two sides are different. For this reason, two groups of communication wires need to be processed, and in order to increase the processing speed and efficiency, the processing practice in the industry is to fix the two groups of communication wires onto a fixture, and then bind the two groups of communication wires on a conventional conveying line and convey the wires to each processing equipment station to process the two groups of communication wires at one time. Because the core wire preprocessing sections of two groups of communication wires on the same clamp are separated by an angle, and the conveying mechanism does not have a turning function, no matter the laser circular cutting equipment or the insulating glue layer removing and core wire fine cutting finishing equipment is used, the angle of the working head of the equipment mechanism is required to be adjusted to deal with another layer after the core wire preprocessing sections of one group of communication wires are processed, so that the time is wasted, the production efficiency is influenced, and the positioning error is easily generated after the working head of the equipment mechanism is adjusted, so that the processing precision of the core wires is influenced.

Certainly, in order to overcome the above problems, some enterprises arrange workers on each equipment station for core wire processing to adjust the angle of the clamp, and then switch the positions of the core wire preprocessing sections at the front ends of the two groups of communication wires to cater to the working head on the equipment. Thus, although the device mechanism working head does not need to be adjusted again, the following problems still exist:

1) the labor intensity of workers is high, a plurality of batches of workers need to be arranged for rotation, and the labor cost of enterprises is increased;

2) the operation time of workers is long, the action may be deformed, the adjustment angle of the clamp is inaccurate, the processing precision of the core wire is reduced, and the defective rate is increased.

Therefore, a conveying mechanism for processing a communication wire core wire, which can automatically complete the turning function of a clamp, is urgently needed in the industry at present.

Disclosure of Invention

In order to solve the above technical problems, an object of the present invention is to provide a conveying mechanism with a clamp overturning function for processing a core wire of a communication wire, which can convey a clamp to a designated station and overturn the clamp by a specific angle, so as to process two groups of communication wires with different size processing requirements fixed on the clamp, thereby improving the working efficiency and ensuring the core wire processing quality.

The technical scheme of the invention is as follows: a conveying mechanism with a clamp overturning function for communication wire core wire processing comprises a clamp for clamping two groups of communication wires with different sizes and processing requirements and a conveying line body for conveying the clamp, and is characterized in that the conveying line body comprises a guide rail and a servo belt conveying mechanism, and push blocks for pushing the clamp to advance along the guide rail are fixed on a belt of the servo belt conveying mechanism at intervals; the turning mechanism comprises a pneumatic finger driven by a first lifting cylinder to lift, a left pivoting frame and a right pivoting frame which are driven by the pneumatic finger to clamp left and right, and conical lugs are symmetrically arranged on the left pivoting frame and the right pivoting frame and are respectively matched with conical holes arranged on two sides of the clamp; the turnover mechanism also comprises an ejector rod for driving the clamp to turn around the conical convex block and a second lifting cylinder for driving the ejector rod to move; the automatic control system further comprises a PLC controller electrically connected with the servo belt conveying mechanism, the first lifting cylinder, the pneumatic finger and the second lifting cylinder.

Furthermore, the guide rail is an oblique guide rail of an oblique positioning fixture and comprises a high guide vertical plate and a low guide vertical plate which are arranged at intervals, a bearing guide groove for supporting the bottom of the fixture is formed in the top of the low guide vertical plate, an inclined surface for supporting the lifting fixture is formed in the top of the high guide vertical plate, the belt is located between the high guide vertical plate and the low guide vertical plate, and the pneumatic finger is attached to the high guide vertical plate.

Furthermore, the ejector rod is arranged at the bottom of the low guide vertical plate, and the bottom surface of the bearing guide groove of the low guide vertical plate is provided with an opening for ejecting the ejector rod.

Furthermore, the clamp is specially designed and comprises a core wire processing section clamping head and a wire body section clamping seat detachably connected with the core wire processing section clamping head, wherein the core wire processing section clamping head comprises a clamping head body block, the clamping head body block is symmetrically provided with assembly inclined planes up and down, an included angle a is formed between the two assembly inclined planes, and a is more than or equal to 45 degrees and less than or equal to 90 degrees; each assembly inclined plane is provided with a chuck embedding groove for embedding the core wire processing section, a plurality of branching notches for separating the core wire processing sections are transversely arranged at equal intervals on the top of the chuck embedding groove, a chuck gland for covering the corresponding chuck embedding groove is hinged on the chuck body block, and a chuck gland locking mechanism is arranged between the chuck gland and the chuck body block in a matching manner; the wire rod section clamping seat comprises a clamping seat body block which is provided with an assembly concave cavity up and down, a clamping seat embedding groove for embedding the wire rod section is formed in the bottom surface of each assembly concave cavity, a clamping seat pressing cover for covering the assembly concave cavity is hinged to the clamping seat body block, and a clamping seat pressing cover locking mechanism is arranged between the clamping seat pressing cover and the clamping seat body block in a matched mode; the left side and the right side of the clamp seat body block are both provided with the tapered holes.

Furthermore, the core wire processing section clamping head and the wire rod section clamping seat are connected through a double-sided elastic clamping mechanism or are clamped through a key groove structure and then are connected and fixed through a connecting piece.

Furthermore, the double-sided elastic clamping mechanism comprises two elastic clamping hooks symmetrically arranged at the front end of the clamp seat body block and a convex block arranged on the clamp seat body block, and clamping grooves respectively corresponding to the two elastic clamping hooks are symmetrically arranged on the convex block.

In the actual process of processing the communication wire core wire, in view of material saving, a single communication wire is generally bent into a U shape, and both ends of the communication wire are processed simultaneously. In order to match with the processing mode, two chuck embedding grooves are symmetrically arranged on each assembling inclined plane left and right, and each chuck embedding groove is correspondingly provided with a chuck pressing cover; and two clamping seat embedding grooves are formed in the bottom surface of each corresponding assembly concave cavity and are respectively connected with the two clamping head embedding grooves on the corresponding assembly inclined surface.

For each assembly concave cavity, two parallel sections of the communication wire bent into a U shape are clamped into the two clamping seat embedding grooves, and an arc section between the two parallel sections can be exposed out of the clamping seat of the wire section. Certainly, due to the fact that the two-sided clamp is different in size of processing the core wires at the front ends of the communication wires clamped on the two sides, the communication wires on one side can protrude forwards during installation, the arc-shaped section on the double-sided clamp can not be exposed outside the clamping seat of the wire, and therefore the two clamping seat embedded grooves on one assembling concave cavity are communicated through the arc-shaped grooves during design, so that the U-shaped embedded grooves are integrally formed and used for embedding the wire section of the whole communication wire.

Furthermore, the chuck gland locking mechanism is an elastic buckle mechanism, for example, a lock hook is arranged on the chuck body block, and a lock groove which is matched with the lock hook is arranged on the chuck gland; or the chuck gland locking mechanism is a connecting piece, such as a screw, a bolt or a pin.

the position of the turnover mechanism on the whole conveying mechanism is actually a placement station of core wire processing equipment, such as a circular cutting aluminum foil laser machine, an aluminum foil removing mechanism, a circular cutting insulating glue layer laser machine, an insulating glue layer removing mechanism and the like.

The front end of the wire section of each communication wire without being stripped is divided into a plurality of treated core wire pretreatment sections.

The fixture is placed on the guide rail, and under the control of the PLC, the servo belt conveying mechanism drives the push block to accurately and sequentially convey the fixture to the station where each turnover mechanism is located and stop.

When the clamp reaches the position of the turnover mechanism, the first lifting cylinder drives the pneumatic fingers to lift, so that the left pivoting frame and the right pivoting frame are located on two sides of the clamp, and then the pneumatic fingers work, so that the left pivoting frame and the right pivoting frame are clamped to jack the conical lugs into the conical holes on two sides of the clamp. And then, the corresponding processing equipment processes a group of communication wires in the fixture, after the processing is finished, the second lifting cylinder drives the ejector rod to jack up so that the fixture is turned over, another group of communication wires to be clamped is sent to a specified angle position and processed by the corresponding processing equipment, and after the processing is finished, the servo belt conveying mechanism acts again to send the fixture to the next turnover mechanism and the station where the corresponding processing equipment is located.
