Description

Technical Field

[0001] This invention belongs to the field of wire harnesses, and specifically relates to an automated testing device for wire harnesses. Background Technology

[0002] Currently, after wire harness production and processing, a simple continuity test is performed. Existing tests are usually conducted in a static state, or after the wire harness has undergone a series of stretching and bending operations, it is then connected to a testing instrument for electrical testing. However, these tests still operate in a static state. In actual use, wire harnesses often work in sync with mechanical equipment. If the electrical performance of the wire harness becomes abnormal during this movement, it can lead to unexpected malfunctions or even shutdowns of the equipment, causing property damage or safety accidents with serious consequences. Therefore, the test data from existing testing equipment is not comprehensive or effective enough, and existing testing equipment can usually only test wire harnesses one by one, resulting in low efficiency.

The corresponding mounting block drives the round rod to move synchronously, causing the round rod to move under the pressure of the wire harness, thereby changing the bending position of the wire harness. The translation mechanism is controlled to drive the L-shaped plate to move back and forth, simulating the repeated bending of the wire harness in actual use and the changing bending part, further improving the comprehensiveness of the wire harness test.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 An automated testing device for wire harness 001, such as Figure 1-5 and Figure 7-10As shown, it includes a base frame 1 and a detector 2; the detector 2 is connected to the base frame 1. It also includes an installation roller 101, an installation plate 102, a fixing plate 103, a sliding sleeve 104, an electric clamp 105, a connecting assembly, a torsion assembly, and a tension assembly; a connecting assembly is connected to the left and right sides of the base frame 1; the installation roller 101 is connected between the two connecting assemblies; four annularly spaced installation plates 102 are fixed to the installation roller 101; a torsion assembly is connected to the left and right sides of each installation plate 102; a fixing plate 103 is connected to each torsion assembly; a sliding sleeve 104 is slidably connected to each fixing plate 103; an electric clamp 105 is bolted to each sliding sleeve 104; a tension assembly is connected to each sliding sleeve 104; and each tension assembly is connected to a fixing plate 103.

The telescopic end of the electric push rod 301 is fixedly connected to the fixed plate 302. A tension sensor 304 is connected to the upper and lower parts of the fixed plate 302. Each tension sensor 304 is connected to a return spring 303. Both return springs 303 are fixedly connected to a corresponding sliding sleeve 104.

[0021] The connecting components on the right include an electric push rod 601, a fixing block 602, a connecting wire 603, a fixing rod 604, a fixing frame 605, a sliding rod 606, a connecting wire 607, a fixing sleeve 608, a spur gear 609, a conductive disc 610, an elastic telescopic rod 611, a ball 612, and a conductive sleeve 613; the electric push rod 601 is bolted to the right side of the base frame 1; the telescopic end of the electric push rod 601 is fixedly connected to the fixing block 602; the right side of the detector 2 is plugged in. There is a connecting line 603; the connecting line 603 is provided with a threaded part 003, which is screwed onto the fixing block 602; the fixing block 602 is fixedly connected to a fixing rod 604; the fixing rod 604 is welded to a fixing frame 605, and the fixing frame 605 is provided with four annular equidistant rubber parts 004; the fixing frame 605 is fixedly connected to a sliding rod 606; the sliding rod 606 is provided with several protruding strips, and the sliding rod 606 is slidably connected to the mounting roller 101; four protruding strips are inserted into the fixing rod 604. A series of equidistant annular connecting lines 607 are provided, each with a control switch; a fixing bracket 605 is bolted to four equidistant annular fixing sleeves 608; a connector on each connecting line 607 is inserted into a fixing sleeve 608; a fixing rod 604 is fixedly connected to a spur gear 609; a fixing block 602 is connected to a power component, which is connected to the spur gear 609; a conductive sleeve 613 is rotatably connected to the end of the connecting line 603; a conductive disk 610 is fixedly connected to the right side of the fixing rod 604, and the conductive disk 610 is inserted into the conductive sleeve 613; each connecting line 607 has a threaded head 006 at its end, and all threaded heads 006 are screwed into the conductive disk 610; two elastic telescopic rods 611 are fixedly connected to the conductive disk 610; each elastic telescopic rod 611 has a ball 612 fixedly connected to its telescopic end; the conductive sleeve 613 has a groove corresponding to each ball 612, with each ball 612 located in one groove.

[0022] The power assembly includes a drive motor 701 and a second spur gear 702; a second fixing block 602 is bolted to the drive motor 701; the output shaft of the drive motor 701 is fixed to the second spur gear 702, and the second spur gear 702 meshes with the first spur gear 609.

[0023] The rubber part 004 on the fixing frame 605 is thinner and narrower than other parts, which makes it easier for the fixing frame 605 to bend at the rubber part 004.

[0024] Each connector on the second connecting wire 607 is equipped with two elastic locking blocks 005. The connector on the second connecting wire 607 is engaged with the corresponding fixing sleeve 608 through the elastic locking blocks 005, which makes it easy to quickly remove the connector on the second connecting wire 607 from the fixing sleeve 608.

[0025] It also includes a mounting block 401 and a round rod 402; each mounting plate 102 has several four-position grooves 002; each four-position groove 002 is slidably connected to a mounting block 401, and both the mounting block 401 and the mounting plate 102 are magnetic.

[0026] In use, the wire harness 001 is placed manually or by an external feeding device. The terminals of the wire harness 001 to be tested are placed on the electric clamp 105, so that the wires of the wire harness 001 are positioned between the four round rods 402. Figure 3 As shown, the electric clamp 105 then closes to clamp the terminals of wire harness 001. The drive motor 701 is started, and its output shaft drives the second spur gear 702 to rotate the first spur gear 609. This causes the first spur gear 609 to rotate the fixing rod 604, fixing frame 605, sliding rod 606, and mounting roller 101. This, in turn, causes the mounting roller 101 to rotate the mounting plate 102 and its connected parts, allowing the next mounting plate 102 to rotate to the corresponding position of the external feeding device. This facilitates the continued placement of wire harness 001 manually or by the external feeding device. When the fixing rod 604 rotates, it drives the conductive disk 610 to rotate within the conductive sleeve 613, preventing the second connecting wire 607 and the first connecting wire 603 from being twisted and damaged due to the rotation of the fixing rod 604, thus ensuring the service life of the second connecting wire 607 and the first connecting wire 603. During the test, the second connecting wire 607 and the first connecting wire 603 will exhibit some normal bending motion. To ensure the accuracy of the test results, the second connecting wire 607 and the first connecting wire 603 should be periodically inspected. Replace wire 603. When replacing wire 603, pull wire 603 out of the detector 2 and manually unscrew the threaded part 003 of wire 603 from the fixing block 602. This separates the conductive sleeve 613 from the conductive disk 610, causing the conductive sleeve 613 to compress the ball 612, compressing the elastic telescopic rod 611, and causing the ball 612 to disengage from the groove on the conductive sleeve 613. This further separates wire 603 from the conductive disk 610. When replacing the second connecting wire 607, manually press the elastic clip 005 to separate it from the fixing sleeve 608. At the same time, pull the connector of the second connecting wire 607 out of the fixing sleeve 608. Then, rotate the second connecting wire 607 to unscrew the threaded head 006 from the conductive disk 610. Remove the second connecting wire 607 from the fixing rod 604 for replacement. This allows for the periodic replacement of consumable parts, ensuring the accuracy of test results and avoiding the need to replace other parts, thus reducing costs.

[0027] After wire harness 001 is fed, the electric push rod 601 is extended, causing the fixing block 602 to move the fixing rod 604 and its connected parts, so that the connector of the connecting wire 607 is inserted into the terminal of wire harness 001. All wire harnesses 001 are then connected to the detector 2 via the connecting wire 603. The detector 2 is then started. Taking the wire harness 001 corresponding to the mounting plate 102 below as an example, the torsion assembly is controlled to operate. The electric shaft 203 drives the fixing block 201 to rotate horizontally. The rotation of the fixing block 201 simultaneously drives the fixing plate 103 to rotate. The electric shaft 202 drives the fixing plate 103 to rotate vertically. The rotation of the fixing plate 103 drives the sliding sleeve 104 and the electric clamp 105 to rotate. When the sliding sleeve 104 and electric clamp 105 rotate vertically during rotation, the round rod 402 limits the wire harness 001, causing the wire harness 001 to bend at the position of the round rod 402. This simulates the bending of the wire harness 001 during actual use. The electrical performance of the wire harness 001 during the bending process is monitored in real time by the detector 2, thereby testing the impact of the bending of the wire harness 001 on the electrical performance. When the fixing plate 103 rotates, it causes the sliding sleeve 104 and electric clamp 105 to rotate horizontally, causing the wire harness 001 to bend and contact the mounting plate 102. The mounting plate 102 limits the wire harness 001, causing the wire harness 001 to bend at the contact position with the mounting plate 102. When the wire harness 001 bends, the terminals of the wire harness 001 drive the connecting wires. The synchronous movement of the connector of the second wire 607 causes the fixing bracket 605 to bend synchronously with the wire harness 001 at the rubber part 004. Simultaneously, the electric push rod 601 extends, allowing the connector of the second wire 607 to move synchronously with the terminal of the wire harness 001. This prevents the terminal of the wire harness 001 from detaching from the connector of the second wire 607, thus avoiding interference with the testing of the wire harness 001. Furthermore, by controlling the torsion assembly on each mounting plate 102, the fixing plate 103 rotates in different directions, resulting in different bending directions for the wire harness 001 corresponding to each mounting plate 102. This allows for comparison and testing to determine whether different bending directions affect the electrical performance of the wire harness 001. When the wire harness 001 bends, it pulls on the sliding sleeve 104, causing the sliding sleeve 104 to slide on the fixing plate 103. The return spring 303 is stretched, causing the wire harness 001 to bend and simultaneously pulling on the wires and terminals. This simulates the pulling situation between the wires and terminals of the wire harness 001 during actual use, thus testing whether the pulling between the wires and terminals affects the electrical performance of the wire harness 001. The stretching of the return spring 303 also triggers the tension sensor 304, which monitors and records the tension on the wire harness 001. During the test, the extension and retraction of the electric push rod 301 can be controlled, causing the fixed plate 302 to move the tension sensor 304, thereby adjusting the tension on the wire harness 001. This allows for testing the impact of different tension conditions on the electrical performance of the wire harness 001, increasing the sample size of the test data and ensuring the comprehensiveness of the test.Throughout the entire process, the detector 2 remains operational, ensuring that it tests the wire harness 001 at every step the fixed plate 103 performs. By monitoring various data points of the wire harness 001 during the dynamic process, the detector 2 identifies any abnormalities encountered during the dynamic simulation test. If no abnormalities are found, all wire harnesses 001 have passed the test. If an abnormality occurs, the control switch on the connecting wire 607 corresponding to one wire harness 001 is turned on, while the control switches on the connecting wires 607 corresponding to all other wire harnesses 001 are turned off. This process of dynamic simulation testing on each wire harness 001 individually identifies which wire harnesses 001 exhibited abnormalities, facilitating further analysis of the abnormal wire harnesses. This allows for simultaneous dynamic simulation testing of multiple wire harnesses 001, improving testing efficiency while ensuring the comprehensiveness and effectiveness of the test.

[0028] Example 2 Based on Example 1, such as Figure 1-10 As shown, It also includes a fixed plate 3 501, a lifting unit, an electric push rod 2 504, a fixed plate 4 505, a translation mechanism 506, an L-shaped plate 507, and a magnetic block 508; the fixed plate 3 501 is bolted to the rear of the base frame 1; the fixed plate 3 501 is connected to the lifting unit, and two electric push rods 2 504 are connected to the lifting unit, which is used to drive the electric push rods 2 504 to rise and fall; each electric push rod 2 504 has a fixed plate 4 505 fixedly attached to its telescopic end; each fixed plate 4 505 is connected to a translation mechanism 506, which consists of a translation slide rail and two translation sliders, and each translation slider has an L-shaped plate 507 fixedly attached; each L-shaped plate 507 has a magnetic block 508 fixedly attached, and each magnetic block 508 is directly opposite a mounting block 401 below the mounting roller 101, and the magnetic force between the magnetic block 508 and the mounting block 401 is much greater than the magnetic force between the mounting block 401 and the mounting plate 102.

[0029] The lifting unit includes an electric slide rail 502 and an electric slider 503; the electric slide rail 502 is fixedly connected to the fixed plate 3 501; two electric sliders 503 are slidably connected on the electric slide rail 502; each electric slider 503 is fixedly connected to an electric push rod 2 504.

[0030] When testing the wire harness 001 below the mounting roller 101, the electric push rod 2 504 is extended, causing the fixed plate 4 505 to move the translation mechanism 506, L-shaped plate 507, and magnetic block 508, bringing the magnetic block 508 close to the mounting plate 102. Then, the upper fixed plate 3 501 is controlled to slide upwards, and the lower fixed plate 3 501 is controlled to slide downwards. Consequently, the magnetic block 508 drives the corresponding mounting block 401 to slide vertically to the end of its stroke within the limiting groove 002 through magnetic force, with adjacent mounting blocks 401 moving in opposite directions. Simultaneously, the mounting block 401 drives the round rod 402 to move synchronously, causing the four round rods 402 to simultaneously compress the wire harness 001, making the wire harness 001 bend in an S-shape. Then, the two translation mechanisms 506 are operated, causing the two L-shaped plates 507 on the left to move the magnetic block 508 to the right, and the two L-shaped plates 507 on the right to move the magnetic block 508 to the left. The direction of movement causes the corresponding mounting block 401 to move synchronously with the round rod 402, so that the round rod 402 moves under the pressure of the wire harness 001. The translation mechanism 506 is controlled to drive the L-shaped plate 507 to move back and forth, so that the bending position of the wire harness 001 changes, simulating the repeated bending and bending of the wire harness 001 in actual use. The electrical performance of the wire harness 001 during the dynamic change process is monitored in real time by the detector 2, which further improves the comprehensiveness of the wire harness 001 test. The power component drives the mounting roller 101 and mounting plate 102 and their connected parts to rotate, so that other wire harnesses 001 rotate to the bottom of the mounting roller 101. Before this, the electric push rod 504 is controlled to retract, so that the magnetic block 508 moves away from the mounting roller 101 and mounting plate 102, so as to prevent the magnetic block 508 from blocking the mounting plate 102. Similarly, the above dynamic simulation test can be performed on each wire harness 001.

[0031] Example 3 Based on Example 2, such as Figure 5 As shown, It also includes a protective sleeve 403; each mounting block 401 is fixedly connected to a round rod 402; each round rod 402 is rotatably connected to a protective sleeve 403.

[0032] The protective sleeve 403 contacts and presses against the wire harness 001. When the translation mechanism 506 drives the L-shaped plate 507 to move back and forth, the L-shaped plate 507 drives the magnetic block 508 to move back and forth, and then the corresponding mounting block 401 drives the round rod 402 to move back and forth synchronously. The protective sleeve 403 contacts and presses against the surface of the wire harness 001, so that the protective sleeve 403 rotates on the round rod 402. Thus, when the wire harness 001 is dynamically simulated and tested by the tester 2, the round rod 402 is prevented from directly contacting and rubbing against the wire harness 001, thereby avoiding damage to the surface of the wire harness 001.
