Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, and in particular to a core wire pretreatment machine. Background Technology

[0002] Cables are widely used in various fields. In the production and processing, it is often necessary to cut a long wire into different products, such as data cables, headphone cables, power cords, plug connectors, etc., which all involve cutting hundreds of meters of wire into pieces before further processing and testing.

[0003] Chinese utility model patent with announcement number CN212010528U discloses an automatic wire pretreatment machine, which includes a wire feeding module, an upper fixture module, a stripping module, a braiding push module, a braiding press module, a braiding cut and stripping module, a first copper foil application module, a first copper foil wrapping module, a braiding flip module, a braiding press module, a second copper foil application module, a second copper foil wrapping module, an aluminum foil cutting module, an aluminum foil peeling module, a wire loosening module, and a wire exit module arranged in the process sequence, and also includes a control module. The automatic wire pretreatment machine is also equipped with upper and lower circulating tracks arranged at vertical intervals. Several general-purpose fixtures are arranged on the upper and lower circulating tracks. After the wire is clamped by the general-purpose fixtures, it is transferred to each workstation. After completing the pretreatment process, these general-purpose fixtures are collected in sequence and transferred manually or by a transfer vehicle to the front end of the wire pretreatment machine to participate in the process again. The above-mentioned frequent transfer operations may increase unnecessary waiting time, which will reduce the overall operating efficiency and may also cause wear or deformation of the fixtures, affecting the positioning accuracy of the fixtures. In addition, each working unit of the equipment adopts a single-station design, resulting in low production efficiency, which cannot meet the increasingly high requirements of modern industry and production for core wire pretreatment equipment.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

The aluminum foil cutting mechanism, aluminum foil removal mechanism, insulation layer cutting mechanism, insulation layer removal mechanism, wire pre-shaping mechanism, wire sorting mechanism, and wire cutting mechanism all employ a dual-station design. The transmission mechanism includes a first track drive mechanism mounted on the upper part of the frame, a second track drive mechanism mounted below the first track drive mechanism, and a first lifting mechanism and a second lifting mechanism mounted at both ends of the frame. When the first lifting platform of the first lifting mechanism and the second lifting platform of the second lifting mechanism are in a high position, they are on the same horizontal plane as the first track of the first track drive mechanism; when they are in a low position, they are on the same horizontal plane as the second track of the second track drive mechanism.

[0011] As a further embodiment of this utility model, the push block includes a push block body, a limiting guide block rotatably mounted on the push block body via a rotating shaft, and a torsion spring fitted on the rotating shaft. The limiting guide block has an inclined surface that rises from low to high along the forward direction.

[0012] As a further embodiment of this utility model, the first slide rail is slidably mounted on a plurality of slide blocks, each of the slide blocks being mounted on a slide block mounting plate, and the two ends of the slide block mounting plate being fixed to two support plates respectively, the two support plates being used to support the two first rails respectively.

[0014] As a further embodiment of this utility model, the first driving mechanism includes a first linear motor, a first transmission rod connected to the output shaft of the first linear motor, and a first connecting block mounted on the first transmission rod, wherein the first connecting block is connected to the first slide rail.

[0015] As a further embodiment of this utility model, the first lifting mechanism includes a first rotary motor, a first lead screw connected to the output shaft of the first rotary motor, and a first lifting platform threadedly connected to the first lead screw.

[0016] As a further embodiment of this utility model, the first rotary motor is mounted on a mounting plate, and two slide rails are arranged side by side on the mounting plate. A slider is slidably mounted on each of the two slide rails, and a sliding mounting bracket is mounted on each of the two sliders. The sliding mounting bracket is screwed to the first lead screw.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Due to the above structural design, the following mechanisms are sequentially arranged on the same side of the transmission mechanism: aluminum foil cutting mechanism, aluminum foil removal mechanism, insulation layer cutting mechanism, insulation layer removal mechanism, core wire pre-shaping mechanism, core wire sorting mechanism, and core wire cutting mechanism. All of the above processing units adopt a dual-station design, which improves production efficiency. By setting a first track drive mechanism and a second track drive mechanism on the frame, as well as a first lifting mechanism and a second lifting mechanism at both ends of the frame, the first lifting mechanism sends the fixture to the first track drive mechanism. After the first track drive mechanism sends the fixture to each station in sequence, the second lifting mechanism sends the fixture to the second track drive mechanism. The second track drive mechanism then returns the fixture to the first lifting mechanism, thereby completing the cyclic reciprocating operation of the fixture. This reduces unnecessary transfer steps, improves operating efficiency, reduces fixture wear or deformation, and ensures the positioning accuracy of the fixture. Attached Figure Description

[0040] Example:

[0041] like Figure 1-7As shown, this application discloses a core wire pretreatment machine, including a frame 100, a transmission mechanism 200 disposed on the frame 100, and a core wire pre-shaping mechanism 300, a core wire removing mechanism 400, an insulation layer cutting mechanism 500, an insulation layer removing mechanism 600, a core wire pre-shaping mechanism 700, a core wire sorting mechanism 800, and a core wire cutting mechanism 900, all arranged sequentially along the processing direction on the same side of the transmission mechanism 200. The cutting mechanism 900 adopts conventional technical means, but adopts a dual-station design. In this embodiment, the core wire pre-shaping unit is used as an example to briefly explain the above content. The core wire pre-shaping mechanism 700 includes a mounting frame 701, two core wire pre-shaping units 702 arranged side by side on the mounting frame 701, and two limiting units 703 correspondingly arranged in front of the core wire pre-shaping units 702. The limiting units 703 are mounted on the limiting unit mounting frame, and the limiting unit mounting frame is mounted on the frame 100. The two core wire pre-shaping units perform core wire pre-shaping operations on the two products on the fixture, that is, a dual-station operation is adopted, thus improving the production efficiency of core wire pre-processing operations.

[0042] The transmission mechanism 200 includes a first track drive mechanism 201 disposed on the upper part of the frame 100, a second track drive mechanism 202 disposed below the first track drive mechanism 201, and a first lifting mechanism 203 and a second lifting mechanism 204 disposed at both ends of the frame 100. When the first lifting platform 2033 of the first lifting mechanism 203 and the second lifting platform 204 of the second lifting mechanism 204 are in a high position, they are on the same horizontal plane as the first track 2011 of the first track drive mechanism 201; when they are in a low position, they are on the same horizontal plane as the second track 202 of the second track drive mechanism 202. The first track drive mechanism 201... The structure of the first lifting mechanism 201 is the same as that of the second track drive mechanism 202, but the direction of movement is opposite. The structures of the first lifting mechanism 203 and the second lifting mechanism 204 are the same. Through the above structural design, the first lifting mechanism 203 sequentially sends the fixture to the first track drive mechanism 201. After the first track drive mechanism 201 sequentially sends the fixture to each workstation, the second lifting mechanism 204 sends the fixture to the second track drive mechanism 202. The second track drive mechanism 202 returns the fixture to the first lifting mechanism 203, thereby completing the cyclic reciprocating operation of the fixture. This reduces unnecessary transfer steps, improves operating efficiency, reduces wear or deformation of the fixture, and ensures the positioning accuracy of the fixture.

[0043] Specifically, the first track drive mechanism 201 includes two first tracks 2011, a first slide rail 2012 disposed between the two first tracks 2011 and slightly below, and a first drive mechanism 2013 that drives the first slide rail 2012 to perform linear reciprocating motion. The first slide rail 2012 is provided with several push blocks 2014, and a receiving space for placing a fixture is formed between two adjacent push blocks 2014. This results in several receiving spaces corresponding to different workstations being formed on the first slide rail 2012. During operation, the fixture is located in the receiving space and can move along the two first tracks. The first drive mechanism 2013 drives the first slide rail 2012 to advance one station along the product movement direction on the two first tracks 2011, so that the fixture in the current accommodating space is sent to the next accommodating space. Then, the first drive mechanism 2013 drives the first slide rail 2012 to retract and reset, so that the fixture in the next accommodating space slides to the current accommodating space. The first drive mechanism 2013 drives the first slide rail 2012 to reciprocate, so that the fixture moves sequentially in several accommodating spaces on the first slide rail 2012, thereby allowing the products on the fixture to be processed sequentially. Since the first slide rail 2012 needs to transfer the fixture in the first lifting mechanism 203 to the first track drive mechanism 201, and also needs to send the fixture on the first track drive mechanism 201 to the second lifting mechanism 204, the first slide rail 2012 can extend into the first lifting platform 2033 of the first lifting mechanism 203 and the second lifting platform of the second lifting mechanism 204.

[0044] Specifically, the push block 2014 includes a push block body 2014a, a limiting guide block 2014b rotatably mounted on the push block body 2014a via a rotating shaft, and a torsion spring (not shown in the figure) fitted on the rotating shaft. The limiting guide block 2014b has an inclined surface 2014c that rises from low to high along the forward direction. The limiting guide block 2014b is in a spring-like state under the action of the torsion spring. When the first drive mechanism 2013 drives the first slide rail 2012 to move along the forward direction, the limiting guide block 2014b is in a spring-like state. The guide block 2014b can drive the fixture to move in the forward direction. When the first drive mechanism 2013 drives the first slide rail 2012 to move backward, the fixture presses the limiting guide block 2014b along the inclined surface 2014c, causing the torsion spring to deform. The fixture then slides past the limiting guide block from the current accommodating space to the next accommodating space. The limiting guide block 2014b is reset under the action of the torsion spring, so that the current fixture can be driven to move when the first drive mechanism 2013 drives the first slide rail 2012 to move in the forward direction the next time.

[0045] Specifically, the first slide rail 2012 is slidably mounted on a plurality of slide blocks 2015, each of the slide blocks 2015 is mounted on a slide block mounting plate 2016, and the two ends of the slide block mounting plate 2016 are respectively fixed to two support plates 101. The two support plates 101 are respectively used to support the two first rails 2011, and the bottom ends of the two support plates are connected to a horizontal plate to enhance the stability of the entire structure.

[0046] Specifically, a plurality of limiting blocks 2017 are provided on any of the first tracks 2011. By providing a plurality of limiting blocks 2017 on the first tracks 2011, the fixture moving on the first tracks 2011 is limited to prevent the fixture from moving beyond the design allowable range, thereby avoiding equipment damage or safety accidents caused by excessive movement.

[0047] Specifically, the first drive mechanism 2013 includes a first linear motor 2013a, a first transmission rod 2013b connected to the output shaft of the first linear motor 2013a, and a first connecting block 2013c mounted on the first transmission rod 2013b. The first connecting block 2013c is L-shaped. One end of the first connecting block 2013c is connected to the first slide rail, and the other end is fixedly mounted on the first transmission rod 2013b. The free end of the first transmission rod 2013b is rotatably mounted on a support seat through a bearing. The support seat is mounted on the frame.

[0048] Specifically, the first lifting mechanism 203 includes a first rotary motor 2031, a first lead screw 2032 connected to the output shaft of the first rotary motor 2031, and a first lifting platform 2033 threadedly connected to the first lead screw 2032. The first rotary motor 2031 is mounted on a mounting plate 2034. Two slide rails 2035 are arranged side by side on the mounting plate 2034. A slider 2036 is slidably mounted on each of the two slide rails 2035. A sliding mounting bracket 2037 is mounted on each of the two sliders 2036. The sliding mounting bracket 2037 is threadedly connected to the first lead screw 2032. The first lifting platform 2033 is mounted on the sliding mounting bracket 2037. The free end of the first lead screw 2032 is rotatably mounted on a support seat through a bearing. The support seat is mounted on the frame. Through the above structural design, the first rotary motor 2031 can drive the first lifting platform 2033 to move stably up and down along the slide rails.

[0049] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, high production efficiency, and high operational efficiency.

[0050] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
