Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing technology, and in particular to a heat shrink tubing cutting device. Background Technology

[0002] In some terminal connector connection processes, heat shrink tubing is often placed over the crimped terminals and then heat-shrinked to enclose the terminals.

[0003] Before heat shrink tubing is fitted onto terminals, it needs to be cut. In the existing technology, heat shrink tubing is fed in roll form and then cut directly. Cutting the roll heat shrink tubing directly has two problems: firstly, there is no support for the cut; secondly, because the tubing is bent after being rolled, cutting directly results in a flat cut surface, which can lead to insufficient or excessive material when wrapping the terminals. Utility Model Content

[0004] Based on the above, the purpose of this utility model is to provide a heat shrink tubing cutting device that can support the heat shrink tubing during cutting and produce a smooth cut surface.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0027] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] like Figure 1 and 2 As shown, this utility model embodiment provides a heat shrink tubing cutting device, including: a first feeding tube 1, which is straight and includes a first cavity 11; a second feeding tube 2, which is also straight and includes a second cavity 21, the outlet of the first feeding tube 1 and the inlet of the second feeding tube 2 corresponding to each other, and the first feeding tube 1 and the second feeding tube 2 aligned on the same horizontal line; a feeding drive assembly 3, which is disposed between the first feeding tube 1 and the second feeding tube 2, for moving the heat shrink tubing within the first cavity 11 and the second cavity 21; and a cutting assembly 4, which is disposed near the outlet of the second feeding tube 2, and includes a cutting drive part 41, the output end of which is provided with a cutting blade part 42.

[0032] In this embodiment, the entire heat shrink tubing cutting device is mounted on a fixed platform (not shown in the figure). Other crimping terminal mechanisms are also mounted on the fixed platform. Since these are not innovations of this invention, the other components of the fixed platform will not be described in detail here. The principle of this embodiment is as follows: the rolled heat shrink tubing enters the first cavity 11 through the inlet of the first feeding tube 1 for straightening. After exiting the outlet of the first feeding tube 1, the heat shrink tubing enters the second cavity 21 through the inlet of the second feeding tube 2 for a second straightening. To drive the heat shrink tubing to move on the first feeding tube 1 and the second feeding tube 2, the feeding drive assembly 3 between the first feeding tube 1 and the second feeding tube 2 drives the heat shrink tubing to move. After straightening on the second feeding tube 2, a cutting assembly 4 is installed at the outlet of the second feeding tube 2. The cutting drive 41 drives the cutting blade 42 to cut the heat shrink tubing. Because of the straightening, the cut surface remains flat during cutting. During the cutting process, the first feeding tube 1 and the second feeding tube 2 also provide support.

[0033] In some embodiments, such as Figure 1 and 2 As shown, the heat shrink tubing cutting device further includes a first cutting mounting plate 5, which is disposed on the fixed platform. A first cutting fixing plate 51 is disposed above the first cutting fixing plate 51, and a first fixing clamp 511 is disposed on the top of the first cutting fixing plate 51. One end of the first feeding tube 1 is clamped in the first fixing clamp 511. Specifically, one end of the first feeding tube 1 is clamped and fixed by the first fixing clamp 511, and the other end of the first feeding tube 1 extends toward the second feeding tube 2.

[0034] In some embodiments, such as Figure 1 and 2 As shown, a cutting guide plate 52 is also provided on the first tube-cutting fixing plate 51. The cutting guide plate 52 extends away from the first feeding tube 1. A cutting guide port 521 is provided on the side of the cutting guide plate 52 away from the first feeding tube 1. The cutting guide port 521 corresponds to the inlet of the first feeding tube 1. A displacement sensor 53 is provided between the cutting guide port 521 and the inlet of the first feeding tube 1. Specifically, by setting the cutting guide plate 52 and the cutting guide port 521, the rolled heat shrink tubing is guided before entering the first tube cavity 11, ensuring that the heat shrink tubing is straightened as soon as it enters the first tube cavity 11, and preventing bending and jamming at the inlet of the first feeding tube 1. The displacement sensor 53 is used in conjunction with the feeding drive assembly 3 and the cutting assembly 4. The data obtained by the displacement sensor 53 is used to control the movement of the feeding drive assembly 3 and the cutting assembly 4, thereby controlling the cutting length of the heat shrink tubing.

[0035] In some embodiments, such as Figure 1 and2 As shown, the feeding drive assembly 3 includes a first feeding drive unit 31 and a second feeding drive unit 32. The first feeding drive unit 31 includes two first feeding drive motors 311, which are mounted on the first tube cutting mounting plate 5. Each of the output ends of the two first feeding drive motors 311 is provided with a first feeding drive drive wheel 312. The second feeding drive unit 32 includes a feeding double-outlet cylinder 321, which is provided with a feeding slide 322 at each of its two output ends. A feeding mounting shaft 323 is provided on the feeding slide 322. A feeding drive wheel 324 is rotatably mounted on the top of the feeding mounting shaft 323, and a feeding drive follower wheel 325 is rotatably mounted on the bottom of the feeding mounting shaft 323. A feeding drive belt is provided between the feeding drive drive wheel and the feeding drive follower wheel 325. Specifically, in this embodiment, two first feeding drive motors 311 drive the feeding drive drive wheel to rotate, which in turn drives the feeding drive follower wheel 325 to rotate via the feeding drive belt. The feeding drive follower wheel 325 then drives the feeding drive wheel 324 to rotate. When the heat shrink tubing is sandwiched between the two feeding drive wheels 324, the rotation of the feeding drive wheel 324 causes the heat shrink tubing to move. During cutting, the heat shrink tubing needs to be stopped from being fed. In this embodiment, a double-layer feeding cylinder drives the feeding slide 322 to move, causing the feeding drive wheels 324 to move closer or further apart. When the feeding drive wheels 324 are close together, the heat shrink tubing can be fed; when they are separated, the feeding drive wheels 324 do not contact the heat shrink tubing, and the feeding of the heat shrink tubing stops at this point.

[0036] In some embodiments, such as Figure 1 and 2 As shown, the feeding slide 322 includes a feeding sliding base plate 3221, a feeding sliding side plate 3222, and a feeding sliding top plate 3223. A U-shaped mounting opening 3224 is formed between the feeding sliding base plate 3221, the feeding sliding side plate 3222, and the feeding sliding top plate 3223. The feeding mounting shaft 323 is rotatably mounted on the feeding sliding top plate 3223, and the feeding drive follower wheel 325 is located within the U-shaped mounting opening 3224. Specifically, in this embodiment, the feeding drive follower wheel 325 is mounted within the U-shaped mounting opening 3224, and the rotational power is synchronously transmitted to the feeding drive wheel 324 through the feeding mounting shaft 323, without affecting the mutual approach or separation of the two feeding drive wheels 324.

[0037] In some embodiments, such as Figure 1 and 2As shown, the tube-cutting drive unit 41 includes a tube-cutting gripper cylinder 411, and two tube-cutting slides 412 are provided at the two output ends of the tube-cutting gripper cylinder 411. The cutting unit 42 includes a first cutter 421 and a second cutter 422, which are arranged one-to-one on the tube-cutting slides 412. Preferably, the first cutter 421 is located below the second cutter 422. Specifically, in this embodiment, the tube-cutting gripper cylinder 411 drives the two tube slides to move closer or further apart, thereby moving the first cutter 421 and the second cutter 422. The heat shrink tubing is placed between the first cutter 421 and the second cutter 422, and the tube-cutting gripper cylinder 411 drives the first cutter 421 and the second cutter 422 to cut the heat shrink tubing.

[0038] In some embodiments, such as Figure 1 and 2 As shown, in order to fix the second feeding tube 2, a second cutting tube fixing plate 6 is connected to the tube cutting claw cylinder 411. A second fixing clamp 61 is provided on the second cutting tube fixing plate 6, and the second feeding tube 2 is clamped on the second fixing clamp 61.
