Description

Technical Field

[0001] The invention relates to an automatic processing device for the insulation glue layer of a communication wire core wire. Background Art

[0002] With the rapid development and popularization of high-speed data transmission technology and network communication technologies such as 5G, the demand for communication cables is increasing.

[0003] The wires currently used for high-speed network communications are usually composed of a wire core, an insulating rubber layer, an aluminum foil layer, a braided layer (copper foil), and a plastic protective sheath (also called an outer sheath). In actual use, the ends of such wires need to undergo two sets of processing before they can be equipped with various types of connection terminals. The first set of processing is called wire pretreatment in the industry, which mainly includes the processes of stripping the outer sheath, cutting the braided layer, pasting copper foil, and wrapping copper foil. At present, the industry has corresponding automated production equipment to complete these processes.

[0004] The second set of processing technology takes over the first set of processing technology, which is called core wire processing in the industry. If further subdivided, core wire processing includes aluminum foil processing technology for processing aluminum foil and insulating glue layer processing technology for processing insulating glue layer. In detail, the aluminum foil processing technology in the prior art is mainly divided into the pre-cutting of the front end of the core wire, laser ring cutting and removing the aluminum foil. The pre-cutting of the front end of the core wire is to trim the front end of the core wire by a cutting mechanism. This is because the front ends of the rows of core wires fixed on the fixture are often uneven, so they need to be sorted and cut neatly. In addition, the welding length requirements of different wire cores and solder joints on the PCB board are different, so the cutting requirements are also different. At the same time, trimming the front end of the core wire neatly in the early stage is also conducive to the processing of subsequent links. Laser ring cutting uses laser equipment to laser aluminum foil and cut a ring on the aluminum foil. Finally, the aluminum foil is removed, that is, the aluminum foil that has been ring-cut is removed from the core wire by a removal mechanism.

[0005] The insulation layer treatment process is divided into three steps: laser ring cutting, removing the insulation layer, and final fine cutting and trimming of the core wire. Laser ring cutting also uses laser equipment to laser the insulation layer and cut a ring on the insulation layer. Removing the insulation layer means removing the ring-cut insulation layer from the core wire. Fine cutting and trimming means making the final trimming according to the welding length between the front end of the core wire and the PCB board.

[0006] In the traditional treatment of the insulation layer of the core wire, except for the laser ring cutting, the other steps are completed manually. However, it is obvious that the manual operation method has high labor intensity and high cost, and the quality cannot be stably and effectively controlled. For this reason, many automatic core wire insulation layer pretreatment equipment have been born in the industry. This type of equipment transfers the process originally completed by manual work to a specialized organization, greatly improving the execution efficiency and quality stability.

[0007] For example, in a common type of core wire insulation layer processing device, it is usually composed of a wire clamping conveyor line set on a machine table and a laser insulation layer ring cutting machine, an insulation layer removal mechanism and an insulation layer precision cutting mechanism arranged in sequence along its conveying direction. The wire clamping conveyor line uses a clamp to clamp the communication wire to be processed, exposing the core wire part at the front end, and the clamp is driven by a synchronous belt transmission mechanism driven by a servo motor. The insulation layer removal mechanism mainly removes the insulation layer from the core wire through a clamping manipulator driven by a cylinder. The insulation layer precision cutting mechanism positions the core wire through a clamping claw, and then the cutter driven by a cylinder cuts off the front end of the core wire. Since the cylinder is set on a displacement mechanism that can adjust the displacement forward and backward, the front and rear distance relative to the core wire can be adjusted to determine the length of the core wire to be cut. The laser transmitter head of the laser insulation layer ring cutting machine can rotate around the insulation layer on the core wire to ring cut the insulation layer.

[0008] However, after long-term research, we found that the known communication wire core wire insulation layer processing device has the following problems that need to be improved:

[0009] It should be said that in the known technology, removing the insulating layer and fine cutting the core wire are two processes, which are completed by two sets of mechanisms respectively. The disadvantage is that the core wire needs to be transferred between the two sets of mechanisms. It is well known in the industry that the core wire is very fragile after the insulating layer is removed. It is very easy to damage the core wire during the transfer process, causing the core wire to be scrapped, resulting in the complete abandonment of the previous processing steps, which greatly increases the production cost of the enterprise.

[0010] In addition, re-transferring and re-aligning require high adjustment of the subsequent insulation glue layer precision cutting mechanism, increase working procedures, waste time, and reduce production efficiency.

[0011] For this reason, some manufacturers often reintroduce manual labor to achieve the removal and precision cutting steps of the insulating rubber layer. However, this manual operation method is obviously too labor-intensive and inefficient, and the labor cost investment is large for enterprises. Moreover, it is difficult for workers to maintain their movements over time, and a slight mistake will damage other parts of the core wire, causing the quality of the core wire to decline, affecting the subsequent processing links, and making it impossible to stably and effectively control the quality of the core wire. Therefore, the industry urgently needs a better solution. Summary of the invention

[0019] Furthermore, the translation drive mechanism in the integrated pulling and precision cutting mechanism is a first servo cylinder arranged on the transverse adjustment plate and connected to the front and rear adjustment plates, and the transverse adjustment plate is provided with at least two parallel first front and rear guide rails, and the lower part of the front and rear adjustment plates is provided with slide blocks matching with the first front and rear guide rails; the pulling drive mechanism is a second servo cylinder arranged on the front and rear adjustment plates and connected to the working bracket, and the front and rear adjustment plates are provided with at least two parallel second front and rear guide rails, and the lower part of the working bracket is provided with slide blocks matching with the second front and rear guide rails; the first servo cylinder and the second servo cylinder are both electrically connected to the PLC controller or industrial control machine.

[0023] Taking into account the common situation that the core wires need to be soldered on both sides of the PCB board, and there is a drop in the welding position of the core wires, the size processing requirements for the core wires of the communication wires on both sides are different, and the corresponding fine cutting lengths of the front ends of the core wires are also different. Therefore, in order to save the process, it is often necessary to fix two layers of communication wires with different size processing requirements on the fixture, and use two laser insulation adhesive layer ring cutting machines to perform ring cutting on the insulation adhesive layers of the two layers of wires respectively. Therefore, further, the fixture described in the present invention is fixed with two layers of communication wires with different core wire cutting lengths, and the corresponding laser insulation adhesive layer ring cutting machines are also two corresponding to the processing of these two layers of communication wires, which are a first laser insulation adhesive layer ring cutting machine and a second laser insulation adhesive layer ring cutting machine arranged in sequence along the conveying direction of the wire clamping conveyor line, and both are CO 2 The laser aluminum foil circular cutting machine, the second laser insulating adhesive layer circular cutting machine is located between the first laser insulating adhesive layer circular cutting machine and the integrated pulling and fine cutting mechanism.

[0024] The working principle of the present invention is as follows:

[0025] Initially, the communication wires after the previous aluminum foil ring cutting and unplugging treatment are clamped with a fixture and placed on the wire clamping conveyor line. Under the control of the PLC controller or industrial computer, the wire clamping conveyor line transports the fixture and the communication wires to the laser insulation glue ring cutting machine and the unplugging and fine cutting integrated mechanism in turn. The following processing steps are implemented by each mechanism:

[0026] (1) The laser insulation layer cutting machine cuts the insulation layer on the surface of the core wire and then transports it to the next station;

[0027] (2) The integrated pulling and fine cutting mechanism cooperates with the reciprocating transverse driving mechanism and the translation driving mechanism to control the displacement of the transverse adjustment plate and the front and rear adjustment plate, and accurately pushes the working bracket and the first and second pneumatic clamps thereon to the position where the core wire is located;

[0028] (3) Under the drive of the removal drive mechanism, the working support continues to move forward, so that the front end of the core wire passes through the clamping block and the cutter block in sequence. The distance between the stop position of the cutter block and the front end of the core wire, i.e., the length of the core wire to be cut, can be adjusted by controlling the movement of the working support;

[0029] (4) The first pneumatic clamp and the second pneumatic clamp are closed, the cutter assembly is closed to cut off the front end of the core wire, and the clamping assembly clamps the insulating rubber layer;

[0030] (5) The pull-out drive mechanism drives the working bracket to retract, and the insulating rubber layer is pulled out from the surface of the core wire. Repeat steps (1) to (5) to process the insulating rubber layer on the core wire of each clamp communication cable.

[0031] By means of the above scheme, the present invention has at least the following advantages:

[0032] 1. The present invention is equipped with an integrated pulling and fine cutting mechanism, which can simultaneously complete the two steps of pulling out the insulation layer of the core wire and fine cutting the front end of the core wire at one time, simplifying and integrating the functions that could only be completed by two sets of equipment into one set of equipment, which not only improves production efficiency, but also saves production costs of enterprises. It can also avoid the damage that the core wire is susceptible to when transferring after the insulation layer is pulled out in the known technology, effectively prevent the quality of the core wire from decreasing, and eliminate manual work, which greatly reduces the burden on workers.

[0033] 2. The integrated pulling and precision cutting mechanism of the present invention can adjust the stop position of the cutter block on the core wire by controlling the movement of the working bracket through the servo cylinder. The length of the stop position of the cutter block from the front end of the core wire is also the length of the core wire that needs to be cut. Therefore, the present invention can achieve precision cutting of the core wire length, greatly improving the operation accuracy.

[0034] 3. The various mechanisms of the integrated pulling and precision cutting mechanism in the present invention complete various actions in an orderly manner under the control of a PLC controller or an industrial computer, and keep the actions from moving, so it has high working reliability, avoids damage to other parts of the core wire that may be caused during manual operation, and effectively prevents the quality of the core wire from deteriorating.

[0035] 4. The integrated plucking and precision cutting mechanism of the present invention has a simple structure, is easy to assemble, disassemble and maintain, and can save maintenance costs.

[0036] 5. The integrated pulling and fine cutting mechanism of the present invention is designed with a transverse adjustment plate limit sensing switch, a front and rear adjustment plate sensing plate, and a working bracket limit sensing switch to limit the movement distance of the transverse adjustment plate, the front and rear adjustment plate, and the working bracket respectively to prevent their activities from exceeding the control stroke, thereby better ensuring the working reliability of the mechanism of the present invention.
