Description

Technical Field

[0001] The invention relates to the technical field of wire harness processing, and in particular to a highly efficient and automated stripping processing device and process for household wire harnesses. Background Art

[0002] In the field of wire harness processing, the stripping process of wire harness conductors is a crucial link. At present, when stripping wire harness conductors, the common practice is to use a cutter head that matches the size of the wire harness conductor to perform the slitting operation. However, this traditional slitting method has significant disadvantages.

[0003] If the cutting depth is not properly controlled, a large amount of insulation will remain at the end of the wire harness conductor when the cutting depth is insufficient. These excess insulation layers cannot be easily removed by conventional operations, and additional processing steps are required later, which not only increases processing costs but also affects production efficiency.

[0004] On the contrary, once the cutting depth is too large, the damage to the harness conductor cannot be underestimated. Excessive cutting will cause scratches and damage to the surface of the harness conductor, which has a direct negative impact on the crimping quality of the harness terminal. Insecure crimping may increase contact resistance, which in turn causes local heating and affects the stability and safety of the entire circuit system. Moreover, during the later use of electricity in the product, the damaged harness conductor may also cause faults such as open circuit and short circuit, which seriously threatens the normal operation and service life of the product.

[0005] It can be seen that how to ensure the stripping and cutting effect of the wire harness insulation layer while effectively avoiding damage to the surface of the wire harness conductor has become a technical problem that needs to be urgently solved in the current wire harness processing and manufacturing industry. Summary of the invention

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention provides a high-efficiency automatic peeling processing equipment for household wire harnesses, comprising a main gear disc, a driving gear meshing with the main gear disc, and a motor for driving the driving gear to rotate, a wire threading groove is provided at the center of the main gear disc, a supporting bearing is arranged on one side of the main gear disc, a group of guide brackets distributed on both sides of the wire threading groove are positioned and installed on the end surface of one side of the main gear disc, a group of symmetrically arranged knife disc parts are elastically installed between the group of guide brackets, and the wires of the wire harness pass through the wire threading groove and are located between the group of guide brackets and the group of knife disc parts.

[0008] Among them, a support block is provided in the middle of the guide bracket, and side blocks are provided on both sides. The side end of the cutter disc is movably installed in the area between the support block and the side block. A long screw is inserted at the position of the support block and the side block. The long screw moves through the side end of the cutter disc, and the long screw sleeve is provided with a tension spring located between the side end of the cutter disc and the support block. The cutter disc is also equipped with a regular polygonal half blade for cutting into the insulation layer of the wire harness. A group of first-position cylinder parts and second-position cylinder parts for promoting the movement of the cutter disc are provided on the main gear ring side.

[0009] As a preferred technical solution of the device of the present invention: the main gear disc is provided with a group of positioning grooves with square openings, and the support block is provided with positioning blocks matching with the positioning grooves;

[0010] The main gear plate is provided with a bolt insertion hole which is connected with the positioning groove through and through, the positioning block is provided with a screw hole which matches with the bolt insertion hole, and the bolt insertion hole and the screw hole are fastened and installed with fixing bolts.

[0011] As a preferred technical solution for the equipment of the present invention: a guide hole is vertically opened on the side end of the cutter disc, and rod insertion holes are vertically opened on the support block and the edge block. The long screw passes through the rod insertion hole and the guide hole and the long screw protrudes from the end of the rod body of the edge block to tighten the installation nut.

[0012] As a preferred technical solution of the device of the present invention: the transverse width dimension of the regular polygonal half blade of the cutter disc is matched with the spacing dimension of the support blocks of a set of guide brackets.

[0013] As a preferred technical solution of the device of the present invention: a group of first-position cylinder components are distributed at the same diameter position of the cutter disc component, and a group of second-position cylinder components are distributed at the same diameter position of the cutter disc component.

[0014] As a preferred technical solution of the device of the present invention: assuming that the regular polygonal half blade adopts a regular n-gon, the circular angle between the first orientation cylinder part and the second orientation cylinder part is 2π / n.

[0015] As a preferred technical solution of the device of the present invention: the regular polygon of the regular polygonal half blade of the cutter disc member is a regular quadrilateral or a regular hexagon or any regular even-numbered polygon.

[0016] As a preferred technical solution of the device of the present invention: the diameter of the regular polygon inscribed circle of the regular polygon half blade is the same as the diameter of the wire harness conductor of the wire harness wire.

[0017] The present invention also provides a high-efficiency and automatic stripping process for household wiring harnesses, comprising the following contents:

[0018] S1. When the length of the wire harness wire passing through the wire groove of the main gear plate reaches the preset stripping length La, the wire harness wire stops moving forward.

[0019] S2. Perform the first cutting operation on the current position of the wire harness insulation layer: currently a group of cylinder parts at the middle position of the cutter disc part are actuated to push the cutter disc part to completely cut into the wire harness insulation layer.

[0020] S3. The motor drives the driving gear to rotate, and the driving gear drives the main gear disc to rotate toward the direction of another group of cylinder parts that are not in motion. When the other group of cylinder parts that are not in motion are exactly at the middle position of the cutter disc, the motor stops driving the main gear disc to move.

[0021] S4. Perform a secondary cutting operation on the current position of the wire harness insulation layer: a group of cylinder parts currently in the middle position of the cutter disc part is actuated to push the cutter disc part to completely cut into the wire harness insulation layer.

[0022] S5. When the distance that the harness wire continues to move forward reaches the preset insulation retention length Lc, the harness wire stops moving forward and the contents of S2 to S4 are repeated.

[0023] S6. Repeat S1 to S5 to complete the wiring harness insulation layer cutting operation of the wiring harness conductors.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention cuts the insulation layer by two regular polygonal external cutting methods. Although a small amount of insulation layer remains after the first cutting, the second cutting can almost completely cut off the remaining part. In this way, when removing the excess insulation layer at the end of the wire harness conductor, it only needs to be simply clamped and pulled outward, and the excess insulation layer at the end of the wire harness conductor can be completely removed.

[0026] 2. The present invention adopts a regular polygonal half blade, and the contact area between the blade and the wire harness conductor is a small number of "point contacts". While ensuring the insulation stripping and slitting effect, it greatly reduces the damage to the conductor, ensures the crimping quality of the wire harness terminal, improves the stability and safety of the entire circuit system, and extends the product life.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] Embodiment 1: The present invention designs a highly efficient and automated stripping and processing device for household wiring harnesses, such as Figure 1 , Figure 2 , mainly includes a main gear disc 1, a guide bracket 2, a cutter disc 4, a tension spring 5, a long screw 6, a first position cylinder 10 and a second position cylinder 11, a motor 12 and a driving gear 13, and the specific structure configuration is as follows:

[0038] Main chainring 1: Figure 1 , Figure 2 , a threading groove 101 is provided at the center for the wire harness to pass through. A set of square opening positioning grooves 102 are provided on one end face, and a bolt insertion hole 103 is connected to the positioning groove 102, and a support bearing 104 is provided on one side. The main gear plate 1 is stably supported by the support bearing 104, providing an installation foundation for other components. The threading groove 101 ensures the accurate threading position of the wire harness, and the positioning groove 102 and the bolt insertion hole 103 are used for accurate positioning and fastening connection with the guide bracket 2.

[0039] Guide bracket 2: Figure 1 , Figure 2 , Figure 3 , Figure 4A group of guide brackets 2 are positioned and installed on one side end surface of the main gear disc 1 and are distributed on both sides of the threading groove 101. A support block 201 is set in the middle position of each guide bracket 2. The support block 201 is equipped with a positioning block 202 that matches the positioning groove 102. The positioning block 202 has a screw hole 203 that matches the bolt insertion hole 103 and is fastened to the main gear disc 1 by the fixing bolt 3; side blocks 204 are set on both sides of the guide bracket 2. The support block 201 and the side block 204 have a rod insertion hole 205 vertically. The guide bracket 2 plays a role in guiding and supporting the wire harness conductors and the cutter disc 4. The positioning block 202 matches the positioning groove 102, and the screw hole 203 matches the bolt insertion hole 103. With the help of the fixing bolt 3, accurate installation and fixation are achieved. The rod insertion hole 205 is used to cooperate with the long screw 6 to ensure the stable installation and movement guidance of the cutter disc 4.

[0040] Cutter head 4: Figure 1 , Figure 2 , Figure 4 , a group of symmetrically configured cutter discs 4 are elastically installed between a group of guide brackets 2. The side end of the cutter disc 4 is movably installed in the area between the support block 201 and the edge block 204, and a guide hole 402 is vertically opened at the side end. The long screw 6 passes through the rod insertion hole 205 and the guide hole 402, and the long screw 6 protrudes from the end of the rod body of the edge block 204 to fasten the mounting nut 7. The cutter disc 4 is also equipped with a regular polygonal half blade 401 for cutting into the wire harness insulation layer 8. The regular polygonal half blade 401 is a blade with only half the shape of a regular polygon. Under the support and guidance of the guide bracket 2, the cutter disc 4 is installed and position-adjusted with the help of the long screw 6 and the nut 7. The regular polygonal half blade 401 is a key component for cutting the wire harness insulation layer 8.

[0041] Tension spring 5: Figure 1 , Figure 2 , which is sleeved on the long screw rod 6 and is located between the side end of the cutter disc 4 and the support block 201. The tension spring 5 provides elastic support force for the cutter disc 4, so that the cutter disc 4 maintains a certain initial position when not pushed by the cylinder, and can buffer the movement of the cutter disc 4 during the cutting process to avoid excessive impact on the cutter disc 4 and the wire harness conductors.

[0042] Long screw 6: Figure 1 , Figure 2 , Figure 3 , inserted at the support block 201 and the edge block 204, and movably passes through the side end of the cutter head 4, and its threads are distributed in the end area of ​​the rod body. The long screw 6 serves to connect the guide bracket 2 and the cutter head 4, and cooperates with the nut 7 to achieve the installation and position fine-tuning of the cutter head 4, and at the same time provides installation support for the tension spring 5.

[0043] The first cylinder 10 and the second cylinder 11: Figure 1 , Figure 2, Figure 5 , Figure 7 , a group of first-position cylinder parts 10 and a group of second-position cylinder parts 11 are arranged on the ring side of the main gear disc 1. A group of first-position cylinder parts 10 are distributed at the same diameter position of the cutter disc part 4, and a group of second-position cylinder parts 11 are distributed at the same diameter position of the cutter disc part 4. When the regular polygonal half blade 401 is a regular n-gon, the circular angle between the first-position cylinder part 10 and the second-position cylinder part 11 is 2π / n. The first-position cylinder part 10 and the second-position cylinder part 11 are used to push the cutter disc part 4 to move so that the regular polygonal half blade 401 cuts into the wire harness insulation layer 8. The two are distributed at a specific angle to achieve two different-position cutting operations on the wire harness insulation layer 8.

[0044] Motor 12 and driving gear 13: Figure 1 , Figure 2 , Figure 5 , Figure 7 The motor 12 is used to drive the driving gear 13 to rotate, and the driving gear 13 is meshed with the main gear plate 1. The motor 12 provides power, and the driving gear 13 transmits the rotation of the motor 12 to the main gear plate 1, so as to realize the rotation of the main gear plate 1, thereby changing the relative position of the cutter disc 4 and the cylinder part, and completing the two cutting operations of the wire harness insulation layer 8.

[0045] Embodiment 2: The present invention designs a highly efficient and automated stripping process for household wiring harnesses, the specific contents of which are as follows:

[0046] Preparation stage: insert the wire harness wire to be processed into the wire threading groove 101 of the main gear disc 1, ensure that the wire harness wire is located at a suitable position between a set of guide brackets 2 and a set of cutter disc parts 4, start the equipment related system, and set the preset stripping length La and insulation retention length Lc.

[0047] (i) First cutting operation: When the length of the wire harness conductor passing through the wire threading groove 101 reaches the preset stripping length La, the wire harness conductor stops moving forward.

[0048] (ii) At this time, a group of cylinder members (such as the first position cylinder member 10) currently facing the middle position of the cutter head member 4 is in motion, and its output push rod pushes the cutter head member 4 to overcome the elastic force of the tension spring 5, so that the regular polygonal half blade 401 completely cuts into the wire harness insulation layer 8. Figure 5 , Figure 6 After the first cut, most of the wiring harness insulation layer 8 is cut, and only a small amount of insulation layer residue 801 exists in the area along the circumscribed shape of the wiring harness conductor 9.

[0049] (iii) Main toothed disc rotates: the motor 12 starts, driving the driving gear 13 to rotate, and the driving gear 13 drives the main toothed disc 1 to rotate toward the other set of cylinder parts that are not in motion (such as the second position cylinder part 11). When the other set of cylinder parts that are not in motion is exactly at the middle position of the cutter disc part 4, the motor 12 stops driving the main toothed disc 1 to move, so that the cutter disc part 4 accurately reaches the second cutting position.

[0050] (iv) Secondary cutting operation S4: A group of cylinder members (such as the second position cylinder member 11) currently in the middle of the cutter head member 4 is actuated to push the cutter head member 4 to completely cut into the wire harness insulation layer 8 again. Figure 7 , Figure 8 This cutting again divides the majority of the small amount of insulation layer residue 801 after the first cutting, making the insulation layer residue 801 area almost negligible. Since the area where the regular polygonal half blade 401 contacts the wire harness conductor 9 is only a few "point contacts", damage to the wire harness conductor 9 when cutting the insulation layer is effectively prevented.

[0051] ㈤ Circular operation: The wire harness continues to move forward. When the forward distance reaches the preset insulation retention length Lc, the wire harness stops moving forward and the operation steps ㈡ to ㈣ are repeated.

[0052] ㈥ Repeat the contents of ㈠ to ㈤ until the wire harness insulation layer 8 of the wire harness conductor is cut. Subsequently, the wire harness conductor can be cut along the cut position of the wire harness insulation layer 8 according to the fixed length specification, and the excess insulation layer at the end of the wire harness conductor can be removed by simply clamping and pulling out.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
