Description

Technical Field

[0001] The utility model relates to the technical field of wire harness production equipment, in particular to a waterproof plug penetration device used for wire harness production. Background Art

[0002] With the improvement of manufacturing technology, electronic products continue to develop in the direction of high integration and modularization. Various types of home appliances, household cars and other equipment have begun to spread to ordinary families and become a necessity of modern life. General household electronic products have high requirements for waterproof performance due to their wide range of usage scenarios and complex and changeable actual situations. As one of the necessary parts in the high integration and modularization process of electronic products, the electronic wiring harness is ensured to meet the product waterproof requirements by setting fixed blocks and waterproof plugs at the ends of the wire row during the production process. Due to the small size of these accessories, their installation on the electronic wiring harness is often achieved manually in the traditional operation mode. During operation, the operator inserts each wiring harness into the corresponding wire holes of the plug cover and the waterproof plug one by one, such as Fig.11 The structure shown is the wiring harness after the waterproof plug and the plug cover have been inserted, wherein the plug cover 2' is located between the waterproof plug 1' and the end 30' of the wire harness 3', and one end face of the plug cover 2' is provided with a groove 20' to facilitate the waterproof plug 1' to be unable to move after being inserted, and the other end face is provided with a docking port 21'. In the subsequent operation after the wiring is completed, the waterproof plug 1' will be inserted into the groove 20' to lock the end of the wire harness in the docking port 21'. In batch operations, such as Fig.12 As shown, the operator manually places multiple waterproof plugs 1' and plug covers 2' in order in the pre-prepared fixture 4', and then manually threads them one by one to achieve batch operation. This traditional operation method is not only time-consuming, but also unstable in efficiency due to subjective reasons such as the operator's proficiency and experience. It is impossible to effectively control production capacity and is not conducive to the comprehensive consideration of the quality of automated production line operations. In short, the traditional operation method and supporting operation equipment have the following problems:

[0003] 1) The operation speed is highly dependent on the operator's proficiency, carefulness and experience;

[0004] 2) The operation continuity is weak, and it is easy to make operating errors due to operator fatigue, which in turn leads to a large number of defective products and causes large production losses. Utility Model Content

[0048] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific diagrams. It should be noted that the terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described here can be implemented in an order other than that illustrated or described here. In addition, the term "including" or "having" and any variation thereof are intended to cover non-exclusive inclusions, for example, a product or device containing a series of components or units is not necessarily limited to those components or units clearly listed, but may include other components or components that are not clearly listed or inherent to these products or devices.

[0049] Reference Figure 1 , Figure 2 , Figure 3 The waterproof plug insertion device for wire harness production includes a base plate 10, a first wire plate 21, a second wire plate 22, a first feed assembly, a second feed assembly and a pressing assembly. The first wire plate 21, the second wire plate 22, the first feed assembly and the second feed assembly are all arranged on the base plate 10.

[0050] The first wire plate 21 has a first wire groove 2101, and the second wire plate 22 has a second wire groove 2201, which is located at one side of the first wire plate 21 (located at the rear side of the first wire plate 21 in the structure shown in the figure, and the threading direction is from front to back), and the second wire groove 2201 corresponds to the first wire groove 2101 one by one;

[0051] The first feeding assembly has a first feeding portion for feeding the waterproof plug 901 to the threading position, and the feeding portion is located between the first wire plate 21 and the second wire plate 22;

[0052] The second feeding assembly has a second feeding portion for conveying the bolt cover 902 to the threading position, and the second wire guide 22 is located between the second feeding portion and the first feeding portion;

[0053] The pressing assembly has a vertically lifting pressing end 401, which is located above the second wire plate 22. The pressing end 401 presses from top to bottom on the bolt cover 902, the waterproof bolt 901 and the second wire groove 2201 located at the threading position to meet the threading conditions.

[0054] After this example is configured as above, it is convenient to automatically supply the waterproof plug and the plug cover, and automatically press the two together, and provide guidance for each wire harness when threading the wires to the waterproof plug and the plug cover, so that each wire in the multiple wire harnesses corresponding to the same waterproof plug has an independent threading channel.

[0055] It should be noted that, in the present invention, the number and position relationship of the first wire grooves 2101 and the second wire grooves 2201 correspond to the wire holes on the waterproof plug 901 and the plug cover 902 one by one;

[0056] In addition, each groove of the first wire groove 2101 and the second wire groove 2201 corresponding to the wire harness is an open groove structure, so that after the threading operation is completed, the wire harness can be easily removed and the groove can be cleaned conveniently.

[0057] The position of the second wire plate 22 can be regarded as a threading station (the threading station is actually the area covered by the pressing end of the pressing assembly after being pressed down, and therefore also includes the position of the waterproof plug and the bolt cover located on the front and rear sides of the second wire plate and in contact with the front and rear ends of its second wire groove). The front and rear ends of the second wire groove 2201 are respectively where the waterproof plug 901 and the bolt cover 902 are in place. When the waterproof plug 901 and the bolt cover 902 are both delivered to their positions, the pressing end 401 descends and presses on the bolt cover 902, the waterproof plug 901 and the second wire groove 2201, so that the bolt cover 902 and the waterproof plug 901 cannot be displaced (that is, it is equivalent to manual threading operation, in which a person holds the waterproof plug or the bolt cover and fixes them in position to facilitate threading, but in manual operation, only one of the waterproof plug or the bolt cover can be fixed at the same time, or in batch operation, refer to Fig.12 , it is necessary to prefabricate a specific fixture and manually place the waterproof plug and the plug cover to a specific clamping position), and at the same time, the opening position of the second wire groove 2201 is also closed (combined with Figure 2 and Figure 6 The action mechanism and design purpose can be deduced) to prevent the end of the wire from being lifted up and exposed above the slot opening when the wire harness passes through the second wire slot 2201 during the threading process and cannot be smoothly extended into the wire hole of the bolt cover 902 on the rear side.

[0058] In order to realize the delivery of the waterproof plug to the threading position, the utility model can set the first feeding assembly according to the following structure: In some embodiments, such as Figure 4 As shown, the first wire board 21 has a horizontal first material conveying channel 501 and a vertical first feeding channel (a first feeding block 3101 is already provided therein, so it is not convenient to mark), the first material conveying channel 501 and the first feeding channel intersect and communicate with each other (when the first feeding block 3101 is in the lifting and lowering limit position, its top end surface is flush with the channel bottom surface of the first material conveying channel 501), and the first material conveying channel 501 is connected to the first vibration screening feeding device (not shown in the figure, refer to Fig. 9 );

[0059] The first feeding assembly includes a first feeding block 3101 and a first feeding cylinder 3102, wherein the first feeding block 3101 is located in the first feeding channel;

[0060] The first feeding cylinder 3102 is located below the first feeding block 3101 and is upwardly connected to the first feeding block 3101. Its telescopic rod pushes the first feeding block 3101 after vertical extension and retraction, and lifts the waterproof plug 901 delivered from the first feeding channel 501 to the threading position.

[0061] It should be noted that the first feeding block 3101 and the first feeding cylinder 3102 are combined to realize the function of the first feeding unit.

[0062] In order to realize the delivery of the bolt cover to the threading position, the utility model can set the second feeding assembly according to the following structure: In some embodiments, such as Figure 5 As shown, the second feeding assembly includes a feeding block 3201, a second feeding block 3202 and a second feeding cylinder 3203, wherein:

[0063] The feed block 3201 has a horizontal second feed channel 502 and a vertical second feeding channel (it is inconvenient to mark because the second feed block 3202 is embedded therein), the second feed channel 502 and the second feeding channel intersect and communicate with each other (when the second feed block 3202 is in the lifting and lowering limit position, its top end surface is flush with the channel bottom surface of the second feed channel 502), and the second feed channel 502 is connected to the second vibration screening feeding device (not shown in the figure) that supplies the bolt cover 902;

[0064] The second feeding block 3202 is located in the second feeding channel;

[0065] The second feeding cylinder 3203 is located below the second feeding block 3202 and is upwardly connected to the second feeding block 3202. Its telescopic rod is vertically extended and retracted to push the second feeding block 3202, and lifts the bolt cover 902 delivered from the feeding block 3201 to the threading position / pushing position.

[0066] The utility model is to make the mechanism setting reasonable and avoid the feeding cylinder affecting the normal working of the pushing station and the threading station. Figure 1 , Figure 4 , Figure 8 As shown, the two feeding cylinders are arranged under the base plate 10, and the cylinder shells are fixed by the bracket block 3001 to make them work stably.

[0067] It should be noted that the second feeding block 3202 and the second feeding cylinder 3203 are combined to realize the function of the second feeding unit.

[0068] like Figure 7 The structure of the feeding channel of the utility model is shown, wherein the first feeding channel 501 is arranged in the first wire board 21, and is used to automatically supply the waterproof plug to the front side of the threading station after docking with the first vibration screening feeding device. Fig. 9The first feeding channel is shown docking with the conveyor belt of the vibrating screening and feeding device. Figure 7 In the structure shown, the second feeding channel 502 is arranged in the feeding block 3201, and is used to automatically supply the bolt cover to the rear side of the threading station after docking with the second vibration screening feeding device.

[0069] When the utility model is in operation, in some cases, the embedded groove of the bolt cover is deep, so that after the second feeding part delivers to the threading position, the bottom of the embedded groove of the bolt cover (the end face of the wire hole) has a certain distance from the end of the second wire groove, so that the wire harness may not be accurately inserted into the wire hole due to deformation during this section of travel. Figure 2 As shown, after the bolt cover 902 is delivered to the position, there is a certain distance between the end (rear end) of the second wire groove 2201 and the bottom (wire hole end face) of the bolt cover embedding groove, so that the end of the wire bundle passing through the second wire groove 2201 may collapse or warp due to its own weight, resulting in the problem that it cannot smoothly pass through the bolt cover wire hole. To deal with such problems, the following structure can be set: In some embodiments, such as Figure 5 As shown, the second feeding assembly includes a pushing block 3204 and a pushing cylinder 3205, wherein:

[0070] The pushing block 3204 is located at one side of the second feeding block 3202, and is used to push the bolt cover 902 toward the waterproof plug 901 by a certain distance, so that the end of the second wire groove 2201 contacts the bottom of the embedded groove of the bolt cover 902;

[0071] The pushing cylinder 3205 is disposed on the base plate 10 and is located at one side of the pushing block 3204 , and a telescopic rod of the pushing cylinder 3205 is connected to the pushing block 3204 .

[0072] The utility model eliminates the distance between the bolt cover with the embedding groove and the second wire groove after the bolt cover is lifted into place by means of the pushing block and the pushing cylinder, so that the wire harness can smoothly pass into the wire hole of the bolt cover, thereby ensuring the operation accuracy.

[0073] like Figure 3 As shown, the front end of the push block 3204 has a groove corresponding to the shape of the bolt cover. During the pushing process, the bolt cover 902 delivered to the position by the second feeding part is pushed toward the side of the second wire board, so that the bottom of the embedded groove of the bolt cover 902 contacts the (rear side) end of the second wire groove 2201 on the second wire board. In the structure shown in the figure, the pushing direction of the push block 3204 is from back to front.

[0074] In order to facilitate the stability and guidance of the pusher block during advancement, the utility model can be arranged according to the following structure: In some embodiments, such as Figure 5As shown, the feed block 3201 has a push guide groove, and the push block 3204 is located in the push guide groove and reciprocates in the push guide groove after being driven by the push cylinder 3205. The push guide groove is provided on the feed block to ensure the stability of the push operation, so that the bolt cover that has been delivered can accurately fall into the groove at the end of the push block.

[0075] It should be noted that during the pushing operation, when the bolt cover 902 is pushed toward the second wire groove 2201, in order to avoid the bottom of the bolt cover 902 being blocked, only a part of the structure at the bottom of the second wire groove body is connected to the upper end surface of the second wire plate 22. Figure 2 , Figure 6 In the structure shown, it can be observed that in the direction in which the bottom of the corresponding bolt cover is pushed forward, a gap is formed after a certain distance is left between the bottom of the second wire groove 2201 and the upper end surface of the second wire plate 22. Figure 2 The bolt cover 902 in the structure has not been advanced yet, and has only reached the upper limit of the feeding. Figure 6 The bolt cover 902 has been pushed into the surrounding structure of its embedded groove and is sleeved on the second wire groove 2201, so that the bottom of the bolt cover 902 has been embedded in the gap between the bottom of the second wire groove 2201 and the upper end surface of the second wire block 21.

[0076] The utility model sets the material pressing assembly according to the following structure: in some embodiments, as Figure 1 , Figure 6 As shown, the pressing assembly includes a pressing end 401, a pressing cylinder 402 and a column 403, and the telescopic rod of the pressing cylinder 402 is connected to the pressing end 401;

[0077] The column 403 connects the pressing cylinder 402 and the base plate 10, and is used to fix the pressing cylinder 402 to the base plate 10 so that it has stable working conditions.

[0078] It should be noted that the shape of the lower end surface of the pressing end 401 corresponds to the bolt cover (which has been fed and pushed to the threading position), the waterproof bolt (which has been fed to the threading position) and the second wire groove 2201. Figure 6 It can be observed from the structure shown that the lower end surface of the pressing end 401 is convex in the middle part, corresponding to the second wire groove 2201, and concave on both sides, corresponding to the top of the waterproof plug 901 and the plug cover 902.

[0079] In addition, if Figure 6As shown, a connection structure 404 can be provided between the telescopic rod of the pressing cylinder 402 and the pressing end 401, so that the pressing end 401 can adjust the specific pressing position after reciprocating along the straight line direction on it. This structural setting can be used for different waterproof plug threading conditions (waterproof plugs and plug covers of different models and specifications such as different wire hole numbers or width dimensions). After replacing the corresponding specification of the pressing end, it can accurately cover the waterproof plug, plug cover and second wire groove of the threading station after pressing down.

[0080] Based on the above situation, the utility model can be configured as follows to correspond to the threading operation of waterproof plugs of various specifications: in some embodiments (not shown in the figure), the first wire trough is an independent structure, and the first wire plate is provided with an embedding groove for the first wire trough to be embedded, and the body width of the first wire trough can be set larger to correspond to the width of the waterproof plug of the largest specification applicable to the threading device of the waterproof plug. At this time, the number of wire troughs on the first wire trough can be set to various specifications according to actual conditions, such as three-wire trough system, four-wire trough system, five-wire trough system, etc., which means that there are a corresponding number of wire troughs on the main body of the first wire trough, so as to be used for waterproof plugs and plug covers with a corresponding number of wire holes.

[0081] It should be noted that the column 403 can be fixed on the base plate 10 independently, or can be fixed on the base plate through other intermediate structures under the premise of simplifying the structure. Figure 6 In the structure shown, in order to control the structure width (the structure width can be regarded as equivalent to the length of the second conductor block), the column 403 is fixed to the base plate 10 through the second conductor plate 22.

[0082] In order to realize the in-place detection during the material conveying process, the utility model can be arranged according to the following structure: the waterproof plug penetration device includes a first detection part and a second detection part, wherein the detection end of the first detection part is located on one side of the first feeding part, and is used to detect the feeding in-place status of the waterproof plug; the detection end of the second detection part is located on one side of the second feeding part, and is used to detect the feeding in-place status of the plug cover.

[0083] like Fig.10 The structure shown in the figure, the utility model constructs a set of detection components by setting the first detection part and the second detection part, so as to realize the real-time detection of the delivery status of the materials (including the waterproof plug and the plug cover) in the threading operation, determine the lifting timing of each feeding block (when it is lowered to a low position, it is material collection, and when it is lifted to a high position, it is material feeding / unloading), and realize the determination of the action timing of the first feeding part and the second feeding part. In the structure shown in the figure, the first detection part 601 is located on one side of the second detection part 602, and the two can be fixed on the base plate 10 through a bracket structure (not shown in the figure).

[0084] Based on this example, the utility model can use a beam-type photoelectric switch to realize the first detection unit and the second detection unit in some of the preferred embodiments. Alternatively, the utility model can also use a proximity switch (including a contact mechanical switch solution such as a travel switch and a micro switch) to realize the functions of the first detection unit and the second detection unit. When a proximity switch is used, ear plates can be respectively set at the high and low positions of each feed block so that it protrudes from one side of the feed block. After the proximity switch is set on this side, the position detection of the feed block is realized by triggering the proximity switch with ear plates of different heights.

[0085] like Fig.10 The first detection unit 601 and the second detection unit 602 implemented by the beam-type photoelectric switch are shown. The receiving end and the transmitting end of the first detection unit 601 are respectively located on both sides of the first feeding block 3101, and the receiving end and the transmitting end of the second detection unit 602 are respectively located on both sides of the second feeding block 3202.

[0086] Based on the above example, Figure 1 , Figure 3 As shown, in order to facilitate the arrangement of the first detection unit 601 and make the structure compact and reasonable, the utility model can be provided with an open slot 701 on the first wire plate 21, so that the slot is connected to the first feeding channel, and the transmitting end / receiving end of the first detection unit 601 is placed therein so that it is located on one side (front side) of the first feeding block 3101, as shown in FIG. Figure 3 As shown, another open slot 702 is provided on the second wire plate 22, and the slot is opened to a depth that allows the receiving end / transmitting end of the first detection unit 601 placed therein to be located on the other side (rear side) of the first feeding block 3101, so as to perform real-time detection of the feeding status of the waterproof plug 901. To correspond to the setting of the transmitting end or receiving end of the second detection unit 602, the setting structure of the transmitting end or receiving end of the first detection unit 601 can be referred to, as shown in FIG. Figure 5 As shown, a third slot 703 is opened on the feeding block 3201, and the transmitting end and the receiving end of the second detection part 602 are set in cooperation with the opening slot 702 already opened on the second wire board 22, so that the two are respectively located on both sides of the second feeding block 3202.

[0087] It should be noted that the light signal emitted by the transmitting end of the through-beam photoelectric switch passes through the wire hole of the waterproof plug or bolt cover and is received by the receiving end, or is blocked by the first feeding block or the second feeding block, so as to serve as the on / off detection signal. To this end, the transmitting end and the receiving end need to be set at specific positions facing a wire hole on the waterproof plug or bolt cover.

[0088] In addition, if Fig. 9 As shown, in order to detect whether the lifting and feeding of the first feeding block 3101 is in place, a through hole 800 can be provided on the first feeding block 3101 to facilitate the signal of the photoelectric switch of the first detection unit 601 to pass through. Fig. 9In the structure shown, through holes 800 corresponding to the wire holes of the waterproof plug 901 are set on the first feeding block 3101, and the transmitting end or the receiving end of the first detection unit 601 can be set on both sides of the vertical position of any through hole. Since the lifting of the first feeding block 3101 also needs to cooperate with the operation sequence of the vibration screening equipment, and the setting of such electric control logic belongs to the prior art, the utility model will not be described in detail.

[0089] The utility model can be combined with a vibrating plate to feed materials, and after cooperating with the conveyor belt connecting the first feeding channel and the second feeding channel, two sets of vibrating screening and feeding devices are constructed for conveying plug covers and waterproof plugs respectively, and the vibrating plate continuously conveys the waterproof plugs and plug covers after adjusting the angle to the corresponding feeding channels. Fig. 9 In the structure shown, the first feeding channel 501 arranged in the first wire board 21 is connected to the first conveyor belt A1, and the first vibrating screening feeding device (not shown in the figure) is connected through the conveyor belt to obtain the waterproof plug.

[0090] To sum up, the utility model provides a waterproof plug threading auxiliary device which automatically supplies waterproof plugs and plug covers, automatically presses the two together and has the conditions for smooth threading. The picking and hand-held fixation of waterproof plugs in manual operations are all realized by the device automatically, and manual operations only require threading. Compared with traditional methods and equipment, the operation difficulty is greatly reduced, the operation accuracy is improved, the burden on operators is effectively reduced, and production efficiency is improved.

[0091] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
