Description

Technical Field

[0001] The utility model relates to the technical field of transfer racks, in particular to a transfer rack used for wire harness detection. Background Art

[0002] A wiring harness is a combination of multiple wires or cables used to transmit power, signals, or data between electronic devices and appliances. It connects two or more isolated electronic circuits to enable current flow and supports the functions of various electronic components. After processing, the wiring harness is usually transported to the test bench for testing on a transfer rack rather than being stacked directly on the test bench. This is mainly done to avoid taking up a large amount of work space, as stacking wiring harnesses can easily lead to congestion in the work area on the test bench, hindering the staff's testing operations and affecting production efficiency and safety.

[0003] Most existing wire harnesses are long and flexible. Therefore, when they are stacked on the transport rack, they are not properly supported and isolated, which causes friction and relative movement between the wire harnesses, leading to entanglement between them. This not only requires workers to spend more time to untangle them, increasing the complexity and time cost of the operation; it also easily causes the wire harnesses to be pulled or folded during the inspection process, increasing the risk of deformation or damage to the wire harnesses, resulting in the inability of the inspection equipment to accurately detect quality problems of the wire harnesses, thereby affecting the accuracy of the wire harness inspection;

[0004] In view of this, in order to overcome the above technical problems, the utility model proposes a transfer rack for wire harness detection, which solves the above technical problems. Utility Model Content

Not only does it not require staff to spend more time to untangle, reducing the complexity of operation and the time cost of detection; it also prevents the wire harness from being pulled or folded during the detection process, reducing the risk of wire harness damage, and ensuring that the detection equipment can accurately detect specific quality problems of the wire harness, thereby improving the accuracy of wire harness detection.

[0024] As an embodiment of the present invention, the guide plate 13 includes an upper clamping plate 14 and a lower clamping plate 15; the upper clamping plate 14 and the lower clamping plate 15 are connected by a support spring 151; an electromagnetic ring 152 is installed at the upper end of the lower clamping plate 15; the groove 141 is opened on one side of the upper clamping plate 14 and the lower clamping plate 15; the grooves 141 of the upper clamping plate 14 and the lower clamping plate 15 are facing each other up and down; the warning light 17 is installed at the upper end of the upper clamping plate 14.

[0025] As an embodiment of the present invention, a baffle 153 is provided in the groove 141 of the lower clamping plate 15 ; the baffle 153 is rotationally connected to the lower clamping plate 15 via a torsion spring; and the baffle 153 is made of PTFE material.

[0026] As an embodiment of the present invention, a circular groove 154 is provided at the upper end of the lower clamping plate 15; a calibration rod 155 is slidably connected in the circular groove 154; the electromagnetic ring 152 is embedded in the bottom of the circular groove 154; and the end of the calibration rod 155 away from the bottom of the circular groove 154 is fixedly connected to the upper clamping plate 14.

[0028] During operation, most existing wire harnesses are long and flexible. Therefore, when the wire harnesses are stacked on the transport rack, they are not properly supported and isolated, which causes friction and relative movement between the wire harnesses, resulting in entanglement between them. This not only requires workers to spend more time to untangle them, increasing the complexity and time cost of the operation; it also easily causes the wire harnesses to be pulled or folded during the inspection process, increasing the risk of deformation or damage to the wire harnesses, resulting in the inability of the inspection equipment to accurately detect quality problems of the wire harnesses, thereby affecting the accuracy of the wire harness inspection;

[0029] To this end, the present invention provides a guide plate 13 so that each wire harness is placed in the groove 141 of the guide plate 13, so that the wire harness is clamped by the insertion rod 143 in the groove 141, so that the wire harness is hung on the transfer rack through the guide plate 13, so that the wire harness can maintain a straight shape in a vertical state, thereby reducing the possibility of relative friction and entanglement between the wire harnesses, not only eliminating the need for workers to spend more time untangling, reducing the complexity of operations, and reducing the time cost of detection; it also prevents the wire harness from being pulled or folded during the detection process, reducing the risk of damage to the wire harness, and ensuring that the detection equipment can accurately detect specific quality problems of the wire harness, thereby improving the accuracy of wire harness detection;

[0030] In the initial state, the calibration rod 155 and the insertion rod 143 are both made of iron material, and the electromagnetic ring 152 in the circular groove 154 is in an energized state, so that the electromagnetic ring 152 generates a magnetic adsorption force on the calibration rod 155, so that the electromagnetic ring 152 drives the lower clamping plate 15 to rise relative to the calibration rod 155, so that the calibration rod 155 continues to approach the circular groove 154 until the calibration rod 155 is inserted into the circular groove 154. At this time, the lower clamping plate 15 and the upper clamping plate 14 are in a connected state, and the connected upper clamping plate 14 and the lower clamping plate 15 are directly opposite each other. In order to prevent the lower clamping plate 15 from shaking left and right when it rises, causing the lower clamping plate 15 to deviate, the calibration rod 155 is inserted into the gap of the support spring 151, thereby affecting the support spring. 151 is compressed, so by providing the inner tube 18, the inner tube 18 is sleeved on the surface of the calibration rod 155, so that the inner tube 18 isolates the calibration rod 155 from the support spring 151, and prevents the lower clamping plate 15 from shaking and causing the calibration rod 155 to be inserted into the gap of the support spring 151, and the outer tube 19 is provided to protect the support spring 151, and prevent foreign matter such as sand and gravel from falling into the gap of the support spring 151 and blocking the compression of the support spring 151, thereby ensuring the normal contraction of the support spring 151, so as to ensure that the calibration rod 155 can be stably inserted into the circular groove 154, so that the lower clamping plate 15 and the upper clamping plate 14 are connected, so that the user can place the guide plate 13 in the guide groove 121;

[0031] When the user needs to place the produced wiring harness on the transfer rack so as to transport the produced wiring harness to the testing equipment for testing, the user needs to first press the controller 16 with one hand so that the controller 16 can control the electromagnetic sheet 145 to operate, so that the electromagnetic sheet 145 generates a magnetic attraction force on the insertion rod 143, so that the insertion rod 143 can squeeze the connecting spring 144 into the slot 142 under the adsorption of the electromagnetic sheet 145, so that the insertion rod 143 in the slots 142 on both sides drives the clamping plates 146 to move away from each other; and the user presses the controller 16 with the other hand so that the controller 16 can control the electromagnetic sheet 145 to operate, so that the electromagnetic sheet 145 can generate a magnetic attraction force on the insertion rod 143, so that the insertion rod 143 can squeeze the connecting spring 144 into the slot 142 on both sides under the adsorption of the electromagnetic sheet 145, so that the insertion rod 143 in the slots 142 on both sides drives the clamping plates 146 to move away from each other. The wire harness is held in one hand and placed in the groove 141 so that the wire harness is located between the two holding plates 146; stop pressing the controller 16 to cut off the power to the electromagnetic sheet 145. At this time, the insertion rod 143 extends out of the slot 142 under the push of the restoring force of the connecting spring 144, so that the insertion rod 143 pushes the holding plate 146 close to the wire harness, so that the holding plate 146 contacts the wire harness. Since the wire harness is made of silicone rubber material, when the insertion rod continues to extend out of the slot 142, the holding plate 146 is blocked by the wire harness, causing the holding plate 146 to release The bending deformation causes the clamping plate 146 to wrap the wire harness, thereby increasing the contact area between the clamping plate 146 and the wire harness, and the clamping plate 146 is made of silicone rubber material, so that the friction coefficient of the clamping plate 146 is large, and thus the friction force between the clamping plate 146 and the wire harness is large, so that the clamping plate 146 can effectively clamp the wire harness, preventing the wire harness from sliding relative to the clamping plate 146 under the action of its own gravity, causing the wire harness to slide down along the clamping plate 146, and the surface of the clamping plate 146 is craggy. The V-shaped groove 147 can further increase the friction coefficient of the surface of the clamping plate 146, thereby increasing the friction between the clamping plate 146 and the wiring harness, ensuring that the wiring harness can be effectively clamped by the clamping plate 146; since a baffle 153 is provided at the notch of the groove 141 of the lower clamping plate 15, when the user pushes the wiring harness to squeeze the baffle 153, the baffle 153 overcomes the torsion force of the torsion spring and rotates into the groove 141, so that the groove 141 opens, thereby allowing the wiring harness to enter the groove 141 of the lower clamping plate 15;When the wire harness passes over the baffle 153, the wire harness no longer generates a pushing force on the baffle 153, so that the baffle 153 rotates in the direction of the wire harness under the action of the torsion spring restoring force, so that the baffle 153 closes the wire harness in the groove 141, and then controls the electromagnetic ring 152 to be powered off, so that the electromagnetic ring 152 no longer generates an adsorption force on the calibration rod 155, so that the lower clamping plate 15 falls under the action of its own gravity, and because the lower clamping plate 15 is connected to the upper clamping plate 14 by the support spring 151, the lower clamping plate 15 stretches the support spring and descends along the wire harness, so that the lower clamping plate 15 limits the middle and lower ends of the wire harness. Because the lower end of the wire harness is easily shaken by the inertial force during the movement of the transfer rack, causing friction and relative movement at the lower end of the wire harness, which leads to the problem of the lower ends of the wire harness being entangled with each other. Therefore, the lower clamping plate 15 is used to limit the middle and lower ends of the wire harness, which can effectively reduce the amplitude of the shaking of the lower end of the wire harness to prevent friction contact between the wire harnesses and the problem of the lower ends of the wire harnesses being entangled with each other, so as to ensure that the adjacent wire harnesses are kept separated from each other during transportation; thereby, there is no need for staff to spend more time to untangle the entanglements, reducing the complexity of the operation and reducing The time cost of detection is low; it also avoids the wiring harness being pulled or folded during the detection process, reduces the risk of wiring harness damage, ensures that the detection equipment can accurately detect specific quality problems of the wiring harness, and thus improves the accuracy of wiring harness detection. After the wiring harness is transported to the detection table, press the controller 16 on the guide plate 13 at one end of the guide groove 121 close to the detection table so that the clamping plate 146 no longer clamps the wiring harness. At this time, the user removes the wiring harness for detection. After the detection is completed, if there is no problem with the wiring harness, it is placed back on the guide plate 13 for clamping and suspension. If there is a problem with the wiring harness, a label is affixed to the surface of the wiring harness and After specifying the problem, place the wire harness on the guide plate 13 for clamping and suspending. Then, remove the guide plate 13 holding the tested wire harness from the end of the guide slot 121 closest to the test platform and insert it from the end of the guide slot 121 away from the test platform. Simultaneously, press the warning light 17, causing it to illuminate. The warning light 17 is designed to indicate that the wire harness clamped by the guide plate 13 is a tested wire harness, making it easier for operators to distinguish it from untested wire harnesses, preventing repeat testing and improving testing efficiency. This further enhances the practicality of the present invention.
