Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.

[0023] In the wire harness manufacturing process, many wire harness plastic parts need to meet waterproof requirements. Plastic parts with an integrally sealed structure offer efficiency and cost advantages in assembly time and the amount of sealing rings used. This part structure requires punching for the holes where wires need to pass through. However, waste, debris, or dust may adhere to these holes and cannot fall into the corresponding collection structure due to gravity. When the wire harness passes through the corresponding holes in the plastic part, it may contaminate the terminals (especially female terminals) on the wire harness.

[0024] In view of the above, embodiments of this application provide a plastic part punching machine to overcome at least one of the above-mentioned technical problems.

[0025] Please see Figure 1 and Figure 2 In this embodiment of the application, the plastic punching machine includes a lower mold 10, a support member 20, and a dust collection member 30.

[0026] The lower mold 10 has a placement cavity 11. The support member 20 includes a support base 21 and a slide 22. The slide 22 is located on one side of the support base 21 along the height direction X and is slidably connected to the support base 21. The lower mold 10 is connected to the side of the slide 22 opposite to the support base 21. The slide 22 has a through hole 221 communicating with the placement cavity 11. The vacuum cleaner 30 is located on one side of the support base 21 along the height direction X and is connected to the support base 21. The vacuum cleaner 30 has a vacuum port 31. The slide 22 has a first position in which the lower mold 10 is located on the side of the vacuum cleaner 30 along the height direction X, and the vacuum port 31 communicates with the through hole 221.

[0027] It is understandable that, such as Figure 8As shown, a processing area 110 is provided on the plastic part punching machine. An upper mold 100 and a lower mold 10 are provided in the processing area 110. The lower mold 10 has a placement cavity 11 for placing the plastic part to be punched. When the upper mold 100 and the lower mold 10 are correspondingly positioned in the height direction X of the plastic part punching machine, the upper mold 100 can be connected to a pneumatic-hydraulic booster cylinder. The pneumatic-hydraulic booster cylinder drives the upper mold 100 to move in the height direction X, thereby punching the plastic part placed in the placement cavity 11.

[0028] Within the processing area 110, a support member 20 is also provided. The support member 20 consists of a support base 21 and a slide table 22, among other structures. The slide table 22 is slidably mounted on the support base 21 and can move in a certain direction. The lower mold 10 is located on the side of the slide table 22 opposite to the support base 21. The slide table 22 can be driven to move in the same direction, and the direction of movement can be set as needed. The movement can be achieved through slide rails, slide grooves, pulleys, etc. Through holes 221 are provided along the height direction X on the slide table 22. The number of through holes 221 is the same as the number of lower molds 10, and their positions correspond one-to-one. A portion of the lower mold 10 can be placed in the corresponding through hole 221, connecting the placement cavity 11 in the lower mold 10 to the corresponding through hole 221. A vacuum cleaner 30 is connected to the support base 21. The vacuum cleaner 30 can be a vacuum generator that can produce negative pressure. Since the slide table 22 can move the lower mold 10 to the first position, in the first position, the lower mold 10 and the upper mold 100 are offset from each other in the height direction X. The lower mold 10 is located on one side of the dust collection component 30 in the height direction X, that is, the slide table 22 moves the lower mold 10 to the top of the dust collection component 30. At this time, the dust collection port 31 on the dust collection component 30 is located directly below the corresponding through hole 221 and is connected to the corresponding through hole 221. When the dust collection component 30 is working, the dust collection port 31 can be in a negative pressure state. Through the dust collection port 31, dust, waste materials and debris in the through hole 221 can be sucked up. Since the placement cavity 11 is connected to the through hole 221, the dust collection component 30 can suck up the waste materials, debris, dust and other materials attached to the plastic parts in the placement cavity 11, especially the waste materials and debris attached to the holes generated by punching, to ensure the cleanliness of the holes, improve the cleanliness of the plastic parts, and avoid contamination of the terminals on the wire harness when the wire harness passes through the holes.

[0029] The vacuum cleaner 30 is connected to the dust collection bag. The dust, waste, and debris sucked up by the vacuum cleaner 30 can enter the dust collection bag for unified collection and treatment, thus avoiding the splashing of the sucked-up dust, waste, and debris and causing secondary pollution.

[0030] Please see Figure 1 , Figure 2 and Figure 3In conjunction with the above embodiments, in some embodiments, the plastic part punching machine includes a connector 40. The connector 40 is located on one side of the dust suction component 30 along the height direction X and is connected to the dust suction component 30. In a first position, the connector 40 is fitted with the slide table 22. The connector 40 has a channel 41, and the dust suction port 31 communicates with the through hole 221 through the channel 41.

[0031] It is understood that a connector 40 is provided on one side of the vacuum cleaner 30 along the height direction X. The connector 40 can be a plate-like structure and is installed on the surface of the vacuum cleaner 30 facing the lower mold 10. The connector 40 has channels 41 that communicate with the vacuum ports 31. The number of channels 41 is the same as the number of vacuum ports 31, and their positions correspond one-to-one. The connector 40 can be made of soft material. When the slide table 22 is in the first position, the connector 40 connected to the vacuum cleaner 30 is fitted against the lower surface of the slide table 22. The channels 41 on the connector 40 communicate with the through holes 221 on the slide table 22. The connector 40 can provide good sealing between the connector 40 and the slide table 22, reducing the risk of air leakage at the connection between the channels 41 and the through holes 221, ensuring that the vacuum cleaner 30 has a large suction force on the through holes 221, so that the vacuum ports 31 can effectively suck up the waste and debris on the plastic parts in the placement cavity 11 through the channels 41 and the through holes 221.

[0032] Please see Figure 4 In conjunction with the above embodiments, in some embodiments, the plastic part punching machine further includes a material take-up member 60. The material take-up member 60 is connected to the support base 21. The slide table 22 has a second position in which the lower mold 10 is located on one side of the material take-up member 60 in the height direction X, and the material take-up member 60 is used to push the material in the placement cavity 11 along the height direction X.

[0033] It is understandable that a material-picking component 60 can also be set on the support base 21. The position of the material-picking component 60 can be set according to the sliding direction of the slide table 22, so that when the slide table 22 slides to a certain position, the lower mold 10 on it corresponds to the material-picking component 60. If the slide table 22 has a second position during the sliding process, in the second position, the lower mold 10 is located on the side of the material-picking component 60 in the height direction X, that is, the lower mold 10 is located on top of the material-picking component 60. After the plastic part placed in the lower mold 10 has undergone punching and dust extraction, it can be picked up in the second position. During picking up, the material-picking component 60 pushes the plastic part in the placement cavity 11 along the height direction X, and a part of the plastic part can be pushed out of the interior of the placement cavity 11. Among them, the material-picking component 60 can lift the plastic part in the placement cavity 11 by about 0.5mm-2mm, without completely ejecting the plastic part. Under the action of the material handling component 60, a portion of the plastic part protrudes from the lower mold 10, making it easier for employees to pick up the material and improving the efficiency of material handling, while also preventing the plastic part from splashing due to its internal elasticity.

[0034] Please see Figure 4 In conjunction with the above embodiments, in some embodiments, the material handling component 60 includes a first driving part 61 and an ejector part 62. The first driving part 61 is connected to the support base 21. The ejector part 62 is located on the side of the first driving part 61 facing the lower mold 10 and is connected to the first driving part 61.

[0035] It is understood that the material handling component 60 may include a first driving part 61 and an ejector part 62. The first driving part 61 may be a cylinder, and the ejector part 62 may be a top block connected to the cylinder's telescopic rod. The first driving part 61 is mounted on the support base 21. By driving the ejector part 62 to move along the height direction X, when the slide table 22 is in the second position, the first driving part 61 can drive the ejector part 62 to engage in the through hole 221, pushing the plastic part in the placement cavity 11 and causing a portion of it to move out of the placement cavity 11 for easy handling by the operator.

[0036] Please see Figure 4 In conjunction with the above embodiments, in some embodiments, the plastic punching machine includes a sensor 70, which is connected to the support base 21. When the slide table 22 is in the second position, the sensor 70 is used to detect the position of the material in the placement cavity 11.

[0037] It is understandable that a sensor 70 is also connected to the support base 21. The sensor 70 can be a through-beam photoelectric sensor, and there are two of them, installed on both sides of the support base 21. When the slide table 22 is in the second position, it is not necessarily the material picker 60 that pushes the plastic part in the placement cavity 11, but it may also be that a plastic part to be punched needs to be placed into the placement cavity 11. In the second position, the two through-beam photoelectric sensors are located on both sides of the slide table 22. When the plastic part to be punched is placed in the placement cavity 11, if the plastic part is not placed in place, part of the plastic part will still be outside the placement cavity 11. This part will block the light emitted by the photoelectric sensor, thereby causing the photoelectric sensor to send an alarm signal to the corresponding alarm device, prompting the operator that the plastic part is not installed in place and part of the plastic part is outside the placement cavity 11. Therefore, the sensor 70 can be used to detect whether the plastic part is fully installed in place during installation, so as to avoid damage to the plastic part by the upper mold 100 during punching due to improper installation.

[0038] Please see Figure 6 In conjunction with the above embodiments, in some embodiments, the plastic part punching machine includes a protective member 80. The protective member 80 is connected to the support base 21, and when the slide table 22 is not in the first position or the second position, the protective member 80 is used to cover the dust suction member 30 and the material picking member 60.

[0039] Understandably, a protective element 80 is also connected to the support base 21. The protective element 80 can provide a certain degree of protection for the dust suction element 30 and the material picking element 60 on the device. When the slide table 22 moves to other positions, not in the first or second position, in order to protect the dust suction element 30 and the material picking element 60 at the first and second positions, the protective element 80 can be covered on the dust suction element 30 and the material picking element 60 to prevent them from being blocked by foreign objects or damaged by external impacts when they are not working.

[0040] Please see Figure 6 and Figure 7 In conjunction with the above embodiments, in some embodiments, the protective component 80 includes a mounting portion 81, a covering portion 82, and a supporting portion 83.

[0041] The mounting portion 81 is located on the side of the picking member 60 opposite to the vacuuming member 30 and is connected to the support base 21. The cover portion 82 is connected to the mounting portion 81 and is used to cover the vacuuming member 30 and the picking member 60. The lifting portion 83 is located between the mounting portion 81 and the picking member 60 and is used to support the cover portion 82.

[0042] It is understood that the material-picking component 60, the dust-collecting component 30, and the collection component 90 (described below) are sequentially arranged on the support base 21, and the arrangement direction of these three components is the same as the sliding direction of the slide table 22. The mounting part 81 on the protective component 80 is located on the side of the material-picking component 60 away from the dust-collecting component 30. The mounting part 81 can be a mounting frame, which can be connected to the support base 21 by bolts, clips, or other structures. The covering part 82 on the protective component 80 can be a corrugated rubber sheet with a certain degree of flexibility and elasticity. One end of it is connected to the mounting part 81, and the other end extends along the sliding direction of the slide table 22. When the slide table 22 slides to a position other than the first and second positions, the other end of the covering part 82 can be pulled to extend it and cover the material-picking component 60 and the dust-collecting component 30, which can provide a certain degree of protection for both. Because the cover 82 has a certain degree of flexibility, it may deform under the influence of other external objects or forces when covering the material picker 60 and the vacuum cleaner 30, causing the cover 82 to shrink. This results in a portion of the material picker 60 or the vacuum cleaner 30 not being covered by the cover 82 (for example, if a heavy object falls on the surface of the cover 82, the coverage area of ​​the cover 82 will be reduced), thus reducing the protective effect on both. Therefore, a support 83 is also provided on the protective member 80. The support 83 can be connected to the support base 21. Its top is a plate-like structure and is horizontally arranged between the mounting part 81 and the material picker 60. When the cover 82 is in a shrunken state (not covering the vacuum cleaner 30 and the material picker 60), the position of the cover 82 between the mounting part 81 and the material picker 60 can be supported by the support 83, keeping it at a certain height for easy unfolding later. When the cover 82 is in the unfolded state (covering the vacuum cleaner 30 and the material picker 60), the lifting part 83 can support the part of the cover 82 located between the mounting part 81 and the material picker 60, so as to prevent the part from being deformed by pressure, causing the cover 82 to shrink and the coverage area to decrease.

[0043] Please see Figure 5 In conjunction with the above embodiments, in some embodiments, the plastic punching machine includes a collecting member 90. The collecting member 90 is connected to the support base 21. The slide 22 has a third position in which the lower mold 10 is located on one side of the collecting member 90 in the height direction X, and the collecting member 90 is used to collect waste material that falls into the placement cavity 11.

[0044] It is understandable that a collecting component 90 is also connected to the support base 21. The collecting component 90 is located on the side of the dust collection component 30 away from the material handling component 60. When the slide table 22 moves to the third position, the lower mold 10 on the slide table 22 is exactly located on the side of the collecting component 90 in the height direction X, that is, on the top of the collecting component 90. The collecting component 90 corresponds to the through hole 221 on the slide table 22. In the third state, the upper mold 100 and the lower mold 10 work together to punch the plastic part placed in the placement cavity 11. The waste material generated after punching can directly enter the collecting component 90 through the corresponding through hole 221. Through the collecting function of the collecting component 90, the waste material that falls off during the punching process can be effectively collected for unified treatment. The waste material will not fall onto the support base 21, ensuring the cleanliness of the surface of the support base 21.

[0045] Please see Figure 5 In conjunction with the above embodiments, in some embodiments, the collecting member 90 includes a hopper section 91 and a conveying section 92. The hopper section 91 is located on one side of the support base 21 in the height direction X and is connected to the support base 21. In a third position, the lower mold 10 is disposed on the side of the hopper section 91 opposite to the support base 21. The conveying section 92 is located on the side of the hopper section 91 opposite to the lower mold 10 and is connected to the hopper section 91.

[0046] It is understandable that the collecting part 90 is composed of a hopper part 91 and a conveying part 92. The hopper part 91 can be a hopper with a large opening at the top and a small opening at the bottom. When the slide table 22 is in the third position, the opening at the top of the hopper part 91 is connected to the through hole 221 on the slide table 22. The waste material generated by the plastic part punched by the upper mold 100 in the placement cavity 11 will enter the hopper part 91 through the through hole 221, and then enter the conveying part 92 through the hopper part 91. The conveying part 92 is a large-diameter metal hose. The other end of the metal hose is connected to the dust collection bag, so that the waste material conveyed by the metal hose can enter the dust collection bag for unified treatment.

[0047] Please see Figure 4 In conjunction with the above embodiments, in some embodiments, the carrier 20 includes a slide rail 23 and a second drive unit 24.

[0048] The slide rail 23 is located on the X-side of the support base 21 in the height direction and is connected to the support base 21. The slide table 22 is slidably connected to the support base 21 via the slide rail 23. The second drive unit 24 is connected to the slide table 22 and is used to drive the slide table 22 to slide.

[0049] Understandably, a slide rail 23 is also provided on the support member 20. The slide rail 23 cooperates with the slide table 22, allowing the slide table 22 to move along the extension direction of the slide rail 23, thereby moving between the first position, the second position, and the third position as needed. The slide table 22 is connected to the second drive unit 24, which can be a high-precision servo motor, driving the slide table 22 to move on the slide rail 23, enabling the slide table 22 to reciprocate between the first position, the second position, and the third position, and to achieve precise positioning.

[0050] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0051] The above provides a detailed description of the plastic punching machine provided in the embodiments of this application, and uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
