[0002] Automotive wiring harnesses are the main network of automotive circuits. Without wiring harnesses, there would be no automotive circuits. A wiring harness is an assembly that connects circuits by crimping copper contact terminals with wires and cables, then molding an insulator or adding an outer metal shell, and bundling the wires together.

(The sentence is incomplete and requires further context to translate accurately.) The upper brush, the upper grinding block and the upper brush are both located in the same vertical and horizontal plane as the wire harness being transported. The lower limit position of the first mounting plate must ensure that the grinding end of the upper grinding block and the cleaning end of the upper brush are in contact with the upper surface of the wire harness being transported. It must also ensure that the upper grinding block, the upper brush and the first mounting plate do not interfere with the transmission action of the corresponding conveying mechanism II. Thus, during the transmission of the wire harness, the upper grinding block and the lower grinding block work together to grind the surface of the wire harness, and the upper brush and the lower brush work together to clean the ground wire harness surface.

[0015] Preferably, it also includes suction heads, branch lines, a main pipeline, and a dust removal device; on the inner top surface of the housing, horizontally arranged branch lines are symmetrically spaced from front to back between the first end cutting and grinding assembly and the tail end cutting and grinding assembly, and each branch line does not interfere with the lifting and lowering movement of the first mounting plate; on the lower surface of each branch line, several suction heads are sequentially and sealedly connected along its length, and the upper ends of all the branch lines converge into one line and are sealed and connected to the lower end of the main pipeline.

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0026] This utility model discloses a grinding device for automotive wiring harnesses, comprising a housing 1, a conveying mechanism I 3, a conveying mechanism II 4, a front end cutting grinding assembly 6, a surface grinding assembly, and a rear end cutting grinding assembly 21; the specific structure is as follows: Figures 1-4 As shown, the housing 1 is a horizontally arranged hollow cuboid structure, and symmetrically arranged horizontally on its left and right sides are two conveying mechanisms I3. Two conveying mechanisms I3 extend vertically into the interior of the housing 1. Inside the housing 1, symmetrically arranged horizontally between the two conveying mechanisms I3 are two conveying mechanisms II4, spaced apart horizontally. The two conveying mechanisms II4 are arranged coplanarly with each corresponding conveying mechanism I3. Vertically embedded in the left and right sides of the housing 1 are transmission holes 2 at positions corresponding to the conveying mechanisms I3. Each transmission hole 2 communicates with the interior of the housing 1, and its size must ensure that the housing 1 does not interfere with the transmission of the wire harness 5 on the corresponding conveying mechanism I3. The conveying mechanisms I3 and II4 of this invention are existing conventional wire harness 5 transmission mechanisms, therefore their structure will not be described in detail here.

[0027] This utility model provides a head end grinding component 6 for grinding the head end cut of the wire harness 5 between the left-side conveying mechanism I3 and the corresponding conveying mechanism II4 inside the housing 1. It also provides a surface grinding component for grinding the surface of the wire harness 5 between the two conveying mechanisms II4 inside the housing 1. Furthermore, it provides a tail end grinding component 21 for grinding the tail end cut of the wire harness 5 between the right-side conveying mechanism I3 and the corresponding conveying mechanism II4 inside the housing 1.

[0028] The front end grinding assembly 6 and the rear end grinding assembly 21 of this utility model have the same structure and are symmetrically arranged on the left and right sides; the rear end grinding assembly includes a third electric push rod 601, a second mounting plate 602, a fourth electric push rod 603, a rib plate, a mounting base 604, a motor 605, a grinding disc 606, a slide rail 609, a slider 610, a fifth electric push rod 607, and an abutment plate 608; Figures 1-4As shown, inside the housing 1, a second mounting plate 602 is horizontally arranged between the right-side conveying mechanism I3 and the corresponding conveying mechanism II4. A third electric push rod 601 is vertically arranged on the upper surface of the housing 1, slightly to the left of the center of the second mounting plate 602. The pushing end of the third electric push rod 601 extends vertically downwards into the housing 1 and is screwed to the upper surface of the second mounting plate 602, slightly to the left of the center, thus driving the second mounting plate 602 to move vertically up and down within the housing 1 above the conveying mechanism I3. The mounting base 604 is a central... A cavity is provided, and the cavity is spaced apart on the left side of the lower surface of the second mounting plate 602. A fourth electric push rod 603 is also horizontally provided on the lower surface of the second mounting plate 602 relative to the left side of the mounting base 604. The fourth electric push rod 603 is located within the coverage area of ​​the second mounting plate 602. The tail of the fourth electric push rod 603 is fixedly connected to the corresponding position of the lower surface of the second mounting plate 602 through a rib plate. Its pushing end is horizontally to the right and screwed to the left side of the mounting base 604, and pushes the mounting base 604 to reciprocate horizontally along the lower surface of the second mounting plate 602.

[0029] like Figures 1-4 As shown, a motor 605 is horizontally arranged inside the mounting base 604. The fixed end of the motor 605 is screwed to the right inner side of the mounting base 604, and its output end extends vertically out of the right side of the mounting base 604 and is screwed to the vertically arranged grinding disc 606 on the same axis, thereby driving the grinding disc 606 to rotate around its own axis and ensuring that neither the second mounting plate 602 nor the mounting base 604 interferes with the rotation of the grinding disc 606.

[0030] like Figures 1-4 As shown, horizontally arranged sliders 610 are symmetrically spaced at intervals on the upper surface of the mounting base 604, and the length of each slider 610 corresponds to the lateral length of the mounting base 604. A horizontally arranged slide rail 609 matching each slider 610 is also provided on the lower surface of the second mounting plate 602 relative to the position of each slider 610. Each slide rail 609 is spaced apart on the right side of the rib plate, and the cooperation between the sliders 610 and the slide rails 609 ensures the stability of the horizontal movement of the mounting base 604.

[0031] like Figures 1-4As shown, the right end of the second mounting plate 602 extends horizontally to the right and is directly above the left end of the right-side conveying mechanism I3. A fifth electric push rod 607 is vertically mounted on the upper surface of the second mounting plate 602 near its right end. The pushing end of the fifth electric push rod 607 extends vertically downward from the lower surface of the second mounting plate 602 and is coaxially screwed to the upper surface of the abutment plate 608. The abutment plate 608 is spaced to the right of the grinding disc 606 and does not interfere with the movement of the grinding disc 606. A wire matching the wire harness 5 is also embedded on the lower surface of the abutment plate 608 at a position relative to the wire harness 5. The groove, and then driven by the cooperation of the third electric push rod 601 and the fifth electric push rod 607, the abutment plate 608 moves vertically downward and abuts and fixes the wire harness 5 on the conveying mechanism I3; on the upper surface of the housing 1, relative to the position of the fifth electric push rod 607 of the first end cutting and grinding assembly 6 and the position of the fifth electric push rod 607 of the tail end cutting and grinding assembly 21, respectively, the housing 1 is vertically embedded and opened through the fifth electric push rod 607, and the abutment hole 7 is used to ensure that the housing 1 does not interfere with the fifth electric push rod 607 moving vertically upward with the second mounting plate 602.

[0032] Specifically, the upper limit position of the second mounting plate 602 must ensure that the mounting base 604 is located above the conveying mechanism I3 and does not interfere with the transmission of the wire harness 5 on the conveying mechanism I3 and the conveying mechanism II4; the lower limit position of the second mounting plate 602 is located above the conveying mechanism I3, and must ensure that the fourth electric push rod 603, the mounting base 604 and the grinding disc 606 all descend between the conveying mechanism I3 and the corresponding conveying mechanism II4, and ensure that the grinding disc 606 and the wire harness 5 are coaxially arranged.

[0033] like Figures 1-4 As shown, several first electric push rods 8 are vertically spaced from left to right on the inner bottom surface of the housing 1, between each conveying mechanism I3 and the corresponding conveying mechanism II4. The tail of each first electric push rod 8 is fixedly installed on the corresponding position on the inner bottom surface of the housing 1, and its pushing end is vertically upward and screwed to the fixed end of the corresponding guide wheel group 9. The rotating end of each guide wheel group 9 is consistent with the forward direction of the wire harness 5, and its setting position is in the same vertical and horizontal plane as the wire harness 5 being transmitted. Thus, driven by the first electric push rods 8, the corresponding guide wheel group 9 rises vertically and guides and supports the wire harness 5 being transmitted. The upper limit position of each guide wheel group 9 must ensure that the rotating end of the guide wheel group 9 is in contact with the lower surface of the wire harness 5 being transmitted, and its lower limit position must ensure that it does not interfere with the mounting base 604 when it descends to the lower limit position.

[0034] This utility model surface polishing assembly includes a fixed base 10, a lower polishing block 11, a lower brush 12, a second electric push rod 13, a first mounting package, an upper polishing block 15, and an upper brush 16; as shown Figures 1-4 As shown, a fixed seat 10 is horizontally provided on the inner bottom surface of the housing 1 between the two conveying mechanisms II 4. On the upper surface of the fixed seat 10, a lower grinding block 11 and a lower brush 12 matching the wire harness 5 are provided at intervals on the left and right relative to the position of the wire harness 5. The lower grinding block 11 and the lower brush 12 are both located in the same vertical and horizontal plane as the wire harness 5 being transmitted. The height of the fixed seat 10 must ensure that the grinding end of the lower grinding block 11 and the cleaning end of the lower brush 12 are in contact with the lower surface of the wire harness 5 being transmitted, and ensure that the lower grinding block 11, the lower brush 12 and the fixed seat 10 do not interfere with the transmission action of the corresponding conveying mechanism II 4.

[0035] like Figures 1-4 As shown, a first mounting plate 14 is horizontally positioned slightly above the center of the interior of the housing 1, relative to the two conveying mechanisms II 4. A second electric push rod 13 is vertically positioned on the upper surface of the housing 1, relative to the position of the first mounting plate 14. The pushing end of the second electric push rod 13 extends vertically downwards into the interior of the housing 1 and is screwed to the center of the upper surface of the first mounting plate 14, driving the first mounting plate 14 to move vertically up and down in the area above the conveying mechanism II 4. On the lower surface of the first mounting plate 14, relative to the position of the wire harness 5, upper grinding blocks 15 and upper brushes 16, matching the wire harness 5, are spaced to the left and right. Both the grinding block 15 and the upper brush 16 are located in the same vertical and horizontal plane as the wire harness 5 being transported. The lower limit position of the first mounting plate 14 must ensure that the grinding end of the upper grinding block 15 and the cleaning end of the upper brush 16 are in contact with the upper surface of the wire harness 5 being transported. It must also ensure that the upper grinding block 15, the upper brush 16, and the first mounting plate 14 do not interfere with the transmission action of the corresponding conveying mechanism II 4. Thus, during the transmission of the wire harness 5, the upper grinding block 15 and the lower grinding block 11 work together to grind the surface of the wire harness 5, and the upper brush 16 and the lower brush 12 work together to clean the surface of the ground wire harness 5.

[0036] like Figures 1-4As shown, on the inner top surface of the housing 1, between the first end cutting and grinding assembly 6 and the last end cutting and grinding assembly 21, horizontally arranged branches 18 are symmetrically spaced from front to back, and each branch 18 does not interfere with the lifting and lowering movement of the first mounting plate 14. On the lower surface of each branch 18, several suction heads 17 are sequentially and sealed along its length. The upper ends of all branches 18 converge into one and are sealed to the lower end of the main pipe 19. The upper end of the main pipe 19 extends vertically upwards from the upper surface of the housing 1 and is sealed to the dust removal device 20. The dust removal device 20 is spaced between the second electric push rod 13 and the third electric push rod 601 of the first end cutting and grinding assembly 6. Through the cooperation of the suction heads 17, branch pipes, main pipe 19, and dust removal device 20, the dust generated during the grinding of the wire harness 5 is collected. This dust removal device is a conventional dust removal mechanism, so its structure will not be described in detail here.

[0037] In this invention, a sensor I is installed on the inner bottom surface of the housing 1 between the left-side conveying mechanism I3 and the leftmost first electric push rod 8. The sensor I is positioned directly facing the wire harness 5 being transmitted and is electrically connected to the third electric push rod 601, the fourth electric push rod 603, the fifth electric push rod 607 and the motor 605 of the first end cutting and polishing assembly 6, as well as all the first electric push rods 8 on the left side. When the first end of the wire harness 5 is transmitted out of the right end of the left-side conveying mechanism I3, the sensor I receives a signal. At this time, all the guide wheel groups 9 on the left side descend to the lower limit position and the first end cutting of the wire harness 5 is polished by the first end cutting and polishing assembly 6.

[0038] In this invention, a sensor II is installed on the inner bottom surface of the housing 1 between the right-side conveying mechanism I3 and the rightmost first electric push rod 8. The sensor II is positioned directly facing the wire harness 5 being transmitted and is electrically connected to the third electric push rod 601, the fourth electric push rod 603, the fifth electric push rod 607 and the motor 605 of the tail end cutting and polishing assembly 21, as well as all the first electric push rods 8 on the left side. When the tail end of the wire harness 5 is about to be transmitted to the right-side conveying mechanism I3, the sensor II detects the signal of the wire harness 5 from present to absent. At this time, all the guide roller groups 9 on the right side descend to the lower limit position, and the tail end cutting of the wire harness 5 is polished by the tail end cutting and polishing assembly 21.

[0039] The working principle of this utility model:

[0040] First, wire harness 5 enters the housing 1 through the corresponding conveying hole 2 via the left-side conveying mechanism I3. When sensor I detects wire harness 5, the left-side conveying mechanism I3 stops working. At this time, the grinding disc 606 of the first-end cutting and grinding assembly 6 descends vertically under the drive of the corresponding third electric push rod 601 until it reaches the coaxial position with wire harness 5. Then, the abutment plate 608 of the first-end cutting and grinding assembly 6 descends vertically under the drive of the corresponding fifth electric push rod 607, pressing the wire harness 5 against the left-side conveying mechanism I3. Then, the pushing end of the fourth electric push rod 603 of the first-end cutting and grinding assembly 6 extends, so that the corresponding grinding disc 606 contacts the first-end cut of the wire harness 5. At this time, the motor 605 of the first-end cutting and grinding assembly 6 starts, and the first-end cut of the wire harness 5 can be ground by the corresponding grinding disc 606. Figure 1 As shown;

[0041] After the initial cutting edge is polished, the polishing disc 606 of the initial cutting edge polishing assembly 6 rises to its upper limit position, and simultaneously all the guide wheel groups 9 on the left side rise to their upper limit positions. At this time, both conveying mechanisms I3 and both conveying mechanisms II4 are activated. Simultaneously, driven by the second electric push rod 13, the upper polishing block 15 and the upper brush 16 descend vertically with the mounting plate and contact the upper surface of the wire harness 5. During the transmission of the wire harness 5, the upper polishing block 15 and the lower polishing block 11 work together to polish the surface of the wire harness 5, and the upper brush 16 and the lower brush 12 work together to clean the polished surface of the wire harness 5. Figure 3 As shown;

[0042] When the detection signal of sensor II changes from present to absent, it indicates that the tail end of wire harness 5 is about to be transmitted to the right-side conveyor mechanism I3. At this time, both conveyor mechanisms I3 and both conveyor mechanisms II4 stop working. Then, all guide wheel groups 9 on the right side descend to their lower limit positions. Simultaneously, the grinding disc 606 of the tail end cutting grinding assembly 21 descends vertically under the drive of the corresponding third electric push rod 601 until it reaches the coaxial position with wire harness 5. Then, the abutment plate 608 of the tail end cutting grinding assembly 21 descends vertically under the drive of the corresponding fifth electric push rod 607, and presses the wire harness 5 against the right-side conveyor mechanism I3. Then, the pushing end of the fourth electric push rod 603 of the tail end cutting grinding assembly 21 extends, so that the corresponding grinding disc 606 contacts the tail end cut of wire harness 5. At this time, the motor 605 of the tail end cutting grinding assembly 21 starts, and the tail end cut of wire harness 5 can be ground by the corresponding grinding disc 606. Figure 4 As shown; after the tail end is polished, the right-side conveyor mechanism I3 is started and the wire harness 5 is transferred to the next process. Then the above steps are repeated to polish the next wire harness 5.

[0043] The beneficial effects of this utility model are:

(The sentence is incomplete and requires further context to translate accurately.) The upper brush, the upper grinding block and the upper brush are both located in the same vertical and horizontal plane as the wire harness being transported. The lower limit position of the first mounting plate must ensure that the grinding end of the upper grinding block and the cleaning end of the upper brush are in contact with the upper surface of the wire harness being transported. It must also ensure that the upper grinding block, the upper brush and the first mounting plate do not interfere with the transmission action of the corresponding conveying mechanism II. Thus, during the transmission of the wire harness, the upper grinding block and the lower grinding block work together to grind the surface of the wire harness, and the upper brush and the lower brush work together to clean the ground wire harness surface.
