Description

Technical Field

[0001] The present invention relates to the technical field of terminal crimping machines, and in particular to an integrated intelligent crimping and testing device for connector terminals of new energy vehicles. Background Art

[0002] Among the many components of new energy vehicles, connector terminals are key components for power and signal transmission, and their processing quality is particularly critical. However, in the current processing of new energy vehicle connector terminals, especially in the crimping and testing stages, there are still some urgent problems that need to be solved.

[0003] In traditional production processes, the crimping and loading of connector harness terminals usually relies on manual labor to simply place multiple wire harnesses with crimp joints into the crimping interface one by one. This is not only inefficient, but also prone to problems such as terminal misalignment and wrong direction due to human negligence, seriously affecting product quality and production continuity. In the inspection link, existing inspection methods are mostly offline inspection or sampling inspection. Offline inspection requires the crimped terminals to be sent to the inspection station separately, which not only increases the production floor space, but also makes the feedback of the inspection results lag, and it is impossible to timely discover and correct problems in the crimping process, resulting in the accumulation of defective products.

[0004] To this end, the present invention proposes an integrated intelligent crimping and testing device for connector terminals of new energy vehicles. Summary of the Invention

[0005] The present invention aims to provide an integrated intelligent crimping and detection device for connector terminals of new energy vehicles to solve the problems raised in the above-mentioned background technology. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an integrated intelligent crimping and detection device for connector terminals of new energy vehicles, comprising a crimping machine, the crimping machine comprising an upper die and a lower die for squeezing the end of a wire harness, a conveyor belt provided on one side of the crimping machine, a plurality of connecting seats provided above the conveyor belt, a connecting strip provided inside the connecting seat, two elastic telescopic rods provided at the bottom of the connecting strip, an arc-shaped clamping sleeve provided on the inner wall of the connecting strip for clamping the wire harness, the conveyor belt being intermittently started and stopped by an external control device, when the end of the wire harness moves to the center position of the upper die and the lower die, the conveyor belt stops running, and the upper die moves downward to crimp the crimping joint at the end of the wire harness; a fixed seat provided on one side of the crimping machine, a cylinder provided above the fixed seat, the cylinder being electrically connected to the control module of the crimping machine, and a detection unit provided at the front end of the cylinder for measuring the size of the crimping joint of the wire harness after crimping.

[0006] Preferably, a fixing cylinder is provided on one side of the upper die, an L-shaped rod is provided inside the fixing cylinder, a vertical rod is provided inside the L-shaped rod, a spring 1 is provided inside the L-shaped rod, the elastic force of the spring 1 is greater than the elastic force of the elastic telescopic rod, and a pressure plate in contact with the outer wall of the wiring harness is provided at the bottom end of the vertical rod, the cross-section of the pressure plate is W-shaped and the pressure plate is elastic.

[0007] Preferably, the detection unit includes a measuring ruler located at the end of the cylinder, the measuring ruler includes a ruler body and two ruler heads, the center areas of the two ruler heads are aligned with the central axis of the wire harness crimping joint, and when the two ruler heads are moved to contact the outer wall of the crimping joint, the distance between the two parallel surfaces of the crimping joint can be measured.

[0008] Preferably, the measuring ruler also includes two ruler heads. An arc-shaped rack is provided at the end of the arc-shaped ferrule, and a square rack engaged with the arc-shaped rack is provided above the conveyor belt. A connecting rod is provided at the bottom of the square rack, and the bottom end of the connecting rod is fixedly connected to the fixed seat. The engagement transmission of the arc-shaped rack and the square rack will cause the arc-shaped ferrule to drive the wiring harness to rotate. When the conveyor belt is stopped, the bottom surface of the crimping joint of the wiring harness is parallel to the detection surface of the chuck 2. In this state, the chuck 2 is displaced toward the crimping joint, and the distance between the other two parallel surfaces of the crimping joint can be measured.

[0009] Preferably, a bending rod is provided above the fixing seat, an electromagnet is provided inside the bending rod, a slider is provided at the end of the electromagnet, an insertion rod is provided at the end of the slider, a spring 2 is provided outside the insertion rod, and the end of the spring 2 is fixedly connected to the protruding part of the insertion rod. When the electromagnet is energized, it will generate a repulsive force with the slider and push the slider to move toward the direction close to the two clamps 2.

[0010] Preferably, a visual sensor is provided on the side of the upper die, which is used to capture the images of the wire harness crimping joint and the crimping area. An electric push rod is provided on the other side of the upper die, and a connecting piece is provided at the end of the electric push rod, and one side of the connecting piece is fixedly connected to the L-shaped rod.

[0012] Preferably, the electromagnet is electrically connected to the control module in the measuring ruler. When the tolerance detected by the measuring ruler is greater than the preset tolerance, the electromagnet will be automatically energized. Under normal conditions, the elastic force of the second spring pulls the slider out of the inside of the two chucks.

[0013] The present invention has at least the following beneficial effects:

[0014] 1. In the present invention, the wire harness is placed on a curved ferrule for fixation. When the crimping joint of a single wire harness moves to the center of the upper and lower dies, the conveyor stops and squeezes the crimping joint of the wire harness. At the same time, the pressure plate also presses the center portion of the wire harness. The two pressing processes are carried out simultaneously, which helps to ensure the overall stability of the wire harness pressing process and is less likely to cause pressure deviation. After the crimping is completed, the conveyor will again drive the connector to move horizontally and equidistantly and repeat the crimping action to complete the automated crimping of the wire harness. Compared with the existing technology, it is not only more efficient, but also reduces problems such as terminal clamping misalignment, improving product quality and production continuity.

[0015] 2. In the present invention, while the crimping is in progress, the conveyor belt will deliver the crimped wire harness to the middle of the two measuring heads and stop. The cylinder will push the two measuring heads to measure the size of the crimped joints. The staff can use the data size of the crimped joints on the display screen to monitor, which is convenient for timely discovery and correction of problems that occur during the crimping process, thereby optimizing the overall crimping process.

[0016] 3. In the present invention, after the crimping joint is measured by the first chuck, the crimping joint completes the change of the detection surface position through the transmission of the arc rack and the square rack. At this time, the cylinder pushes the second chuck to measure the size of the crimping joint again. The data obtained from the two measurements can further accurately confirm the overall size of the crimping joint, ensuring that the crimping has a higher yield rate; when an unqualified wire harness is measured for the first time, the slider will push the unqualified wire harness in the arc ferrule, so that this wire harness is distinguished from other wire harnesses, making it more convenient for the staff to pick it up in time, making the detection process more intelligent.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-9 The present invention provides a technical solution: an integrated intelligent crimping and testing device for connector terminals of new energy vehicles, comprising:

[0029] Example 1

[0030] Crimping machine 1, crimping machine 1 includes an upper die 2 and a lower die 3 for extruding the end of the wire harness. The crimping machine 1 drives the upper die 2 to press the lower die 3 through an intelligent push rod, and extrude the crimping joint placed between the upper die 2 and the lower die 3 to form a regular regular hexagonal joint shape. The above is the existing technology, so it will not be repeated.

[0031] The crimping machine 1 in this scheme is provided with a conveyor belt 4 on one side, and a plurality of connecting seats 5 are provided above the conveyor belt 4 and fixedly connected thereto. The plurality of connecting seats 5 are equidistantly distributed, and the conveyor belt 4 can drive the connecting seat 5 to move laterally in the working state. A connecting strip 6 is provided inside the connecting seat 5, and the connecting strip 6 is slidably connected to the connecting seat 5 in the vertical direction. Two elastic telescopic rods 7 are provided at the bottom of the connecting strip 6, and the two ends of the elastic telescopic rod 7 are fixedly connected to the connecting strip 6 and the connecting seat 5 respectively. The elastic telescopic rod 7 has self-recovering elasticity, and the inner wall of the connecting strip 6 is provided with an arc-shaped clamping sleeve 8 for clamping the wiring harness, and the arc-shaped clamping sleeve 8 is rotatably connected to the connecting strip 6. The arc-shaped clamping sleeve 8 is elastic and has a certain clamping effect on the wiring harness, and the arc-shaped clamping sleeve 8 can drive the wiring harness to rotate above the connecting strip 6.

[0032] The conveyor belt 4 is in an intermittent start-stop working state through an external control device. When the end of the wiring harness is displaced to the center position of the upper die 2 and the lower die 3, the conveyor belt 4 stops running, and the upper die 2 moves downward to crimp the crimping joint at the end of the wiring harness to complete the crimping process; a fixed cylinder 12 is provided on one side of the upper die 2 and is fixedly connected to it, an L-shaped rod 13 is provided inside the fixed cylinder 12 and is slidably connected to it, a vertical rod 14 is provided inside the L-shaped rod 13 and is slidably connected to it, a spring 15 is provided inside the L-shaped rod 13, and the two ends of the spring 15 are fixedly connected to the L-shaped rod 13 and the vertical rod 14 respectively. The elastic force of the spring 15 is greater than the elastic force of the elastic telescopic rod 7. The bottom end of the vertical rod 14 is provided with a pressing plate 16 that contacts the outer wall of the wiring harness and is fixedly connected to it. The cross-section of the pressing plate 16 is W-shaped and the pressing plate 16 is elastic. The elasticity of the pressing plate 16 can completely enter the interior of the connecting seat 5 as the upper die 2 descends, and recover after being detached from the connecting seat 5;

[0033] During the transmission process of the conveyor belt 4, the outer wall of the wire harness above the connecting seat 5 contacts the inclined surface of the side of the pressure plate 16, and under the elastic force of the spring 15, the wire harness will gradually slide to the bottom of the pressure plate 16 and be squeezed by the pressure plate 16. A visual sensor 29 is provided on the side of the upper die 2 and is fixedly connected to it. The visual sensor 29 is used to capture the image of the wire harness crimping joint and the crimping area. An electric push rod 30 is provided on the other side of the upper die 2 and is fixedly connected to it. The visual sensor 29 is electrically connected to the electric push rod 30, and the end of the electric push rod 30 is provided with a connecting piece 31 and fixed to it. Connection, one side of the connecting piece 31 is fixedly connected to the L-shaped rod 13; when the visual sensor 29 detects that the crimping joint at the end of the wire harness is not aligned with the crimping area, the electric push rod 30 will laterally displace the pressure plate 16 according to the specific situation of the deviation, and the spring 15 provides the pressing force on the wire harness for the pressure plate 16, which can drive the wire harness to be slightly displaced inside the arc-shaped clamping sleeve 8 until the clamping joint at the end of the wire harness is aligned with the clamping area. The crimping machine 1 will drive the upper die 2 to continue to crimp the end of the wire harness, ensuring the accuracy of the crimping work and helping to improve the crimping quality of the wire harness.

[0034] Furthermore, a fixing seat 9 is provided on one side of the crimping machine 1 and is fixedly connected thereto, a cylinder 10 is provided above the fixing seat 9 and is fixedly connected thereto, the cylinder 10 is electrically connected to the control module of the crimping machine 1, and when the crimping machine 1 performs crimping, the push rod of the cylinder 10 automatically extends forward a preset distance, and a detection unit 11 is provided at the front end of the cylinder 10 for measuring the size of the wire harness crimping joint after crimping. The detection unit 11 includes a measuring ruler 17 located at the end of the cylinder 10, and the side wall of the measuring ruler 17 is fixedly connected to the end of the cylinder 10. The measuring ruler 17 includes a ruler body 18 and two ruler heads 19. The center areas of the two ruler heads 19 are aligned with the central axis of the wire harness crimping joint, and when the two ruler heads 19 are moved to contact the outer wall of the crimping joint, the distance between the two parallel surfaces of the crimping joint can be measured (the measurement principle here is the same as the distance measurement principle of the electronic vernier caliper in the prior art), ensuring that the size of the crimping joint that is deformed after crimping is qualified, reducing the hysteresis of the feedback of the detection results, and ensuring the quality of the crimped product.

[0035] Automated crimping and testing integrated process:

[0036] The staff can place the wire harnesses to be crimped on top of each connector 5 in advance and clamp them with the arc-shaped clamping sleeve 8, and then start the conveyor belt 4 and the crimping machine 1 to work. During this process, every time the crimping joint of a single wire harness moves with the conveyor belt 4 to the center of the upper die 2 and the lower die 3, the conveyor belt 4 will stop for a while. At the same time, the upper die 2 will descend to squeeze the crimping joint of the wire harness. At the same time, the upper die 2 will also drive the fixing cylinder 12, the L-shaped rod 13 and the pressing plate 16 at the bottom of the vertical rod 14 to press the center part of the wire harness. This pressing process is carried out synchronously with the pressing process of the wire harness ends, which is conducive to ensuring the overall stability of the wire harness pressing process, making the quality of the wire harness crimping better and less prone to pressure deviation. After the crimping is completed, the upper die 2 is reset, and the elastic telescopic rod 7 will also drive the crimped wire harness to reset. At this time, the conveyor belt 4 will again drive the connecting seat 5 to move laterally and equidistantly, so that the next wire harness is moved between the upper die 2 and the lower die 3, and the above actions are repeated to complete the automated crimping of the wire harness. Compared with the existing technology, it is not only more efficient, but also reduces problems such as terminal clamping misalignment, thereby improving product quality and production continuity.

[0037] On the other hand, while the crimping work is being carried out, the conveyor belt 4 will also deliver the crimped wire harness to the middle of the two ruler heads 19 and stop. The cylinder 10 will push the two ruler heads 19 to move to the outer wall of the crimping joint after crimping, and measure the size of the formed crimping joint. The measured data can be directly transmitted to the display screen of the crimping machine 1, so that the staff can monitor the data size of the crimping joint in time, facilitate timely discovery and correction of problems arising during the crimping process, and optimize the overall crimping process.

[0038] According to the above embodiment, embodiment 2

[0039] The measuring ruler 17 also includes two ruler heads 20. The functions of ruler heads 20 and 19 are the same, and they are only used to measure the size of the crimping joint. Ruler heads 20 and 19 are both movably connected to the ruler body 18, and the measuring distance can be freely changed according to measurement needs. The end of the arc-shaped ferrule 8 is provided with an arc-shaped rack 21 and fixedly connected to it. A square rack 22 engaged with it is provided above the conveyor belt 4. A connecting rod 23 is provided at the bottom of the square rack 22 and fixedly connected to it. The overall shape of the connecting rod 23 is L-shaped, and the bottom end of the connecting rod 23 is fixedly connected to the fixed seat 9. The meshing transmission of the arc-shaped rack 21 and the square rack 22 will cause the arc-shaped ferrule 8 to drive the wiring harness to rotate. When the conveyor belt 4 is stopped, the bottom surface of the crimping joint of the wiring harness is parallel to the detection surface of the chuck 2. In this state, the chuck 2 displaced toward the crimping joint can measure the distance between the other two parallel surfaces of the crimping joint.

[0040] Furthermore, a bending rod 24 is provided above the fixing seat 9 and is fixedly connected thereto. The overall shape of the bending rod 24 is L-shaped. An electromagnet 25 is provided inside the bending rod 24 and is fixedly connected thereto. A slider 26 is provided at the end of the electromagnet 25. The slider 26 is located inside the bending rod 24 and is slidably connected thereto. An insertion rod 27 is provided at the end of the slider 26 and is fixedly connected thereto. The insertion rod 27 passes through the electromagnet 25 and the bending rod 24 and is slidably connected to the two. A spring 28 is provided on the outside of the insertion rod 27. The end of the spring 28 is fixedly connected to the protruding portion of the insertion rod 27, and the other end is fixedly connected to the protruding portion of the bending rod 24. The outer wall is fixedly connected, and when the electromagnet 25 is energized, it will generate a repulsive force with the slider 26, and push the slider 26 to move in the direction close to the two chucks 2, until the slider 26 pushes the wiring harness to move a short distance above the arc-shaped sleeve 8. The electromagnet 25 is electrically connected to the control module in the measuring ruler 17. When the tolerance detected by the measuring ruler 17 is greater than the preset tolerance, when the cylinder 10 is pushed forward again, the electromagnet 25 will be automatically energized, and the elastic force of the spring 28 under normal conditions will pull the slider 26 out of the inside of the two chucks 2 and return to the inside of the bending rod 24 again.

[0041] The process of secondary inspection and automatic rejection of defective products:

[0042] After the crimping joint is measured by chuck 1, the connecting seat 5 moving with the conveyor belt 4 will drive the arc-shaped rack 21 and the square rack 22 to engage with each other for transmission, thereby causing the arc-shaped sleeve 8 to drive the wiring harness to rotate slightly until the bottom surface of the clamping joint is parallel to the detection surface of chuck 2. In this state, the crimping joint has completed the change in the position of its own detection surface. At this time, the cylinder 10 pushes chuck 2 forward to move the joint, and the size of the crimping joint that has completed the rotation can be measured again. The data obtained from the two measurements can further accurately confirm the overall size of the crimping joint, ensuring that the crimping has a higher yield rate.

[0043] On the other hand, when the tolerance detected by the measuring ruler 17 in the initial measurement is greater than the preset tolerance, when the cylinder 10 is pushed forward again, the electromagnet 25 will be automatically energized (the electromagnet 25 is energized and de-energized by the control module in the measuring ruler 17). The repulsive force generated by the electromagnet 25 will push the slider 26 to slide forward. In this state, the unqualified wiring harness has moved to the front of the two clamps 2. Therefore, the slider 26 will slide forward at the same time as the two clamps 2 and push the unqualified wiring harness in the arc-shaped ferrule 8, so that this wiring harness is different from other wiring harnesses, making it more convenient for staff to pick it up in time, making the detection process more intelligent. After this, the electromagnet 25 will be de-energized again, and the slider 26 will return to the inside of the bending rod 24 again under the pulling force of the spring 2 28.
