Abstract

This invention relates to the field of testing technology and discloses a testing device, including a base, a tubing bundle assembly, and an anti-tangle assembly. A test head is rotatably mounted at the bottom of the base. The tubing bundle assembly is located on one side of the base and contains a wire harness. One end of the wire harness is connected to the test head, allowing the test head to rotate the tubing bundle assembly. The anti-tangle assembly is located at the top of the base and has a limiting space that allows the tubing bundle assembly to bend. The anti-tangle assembly is connected to the tubing bundle assembly. When the test head rotates the tubing bundle assembly, a portion of the anti-tangle assembly rotates synchronously. In this invention, when the test head rotates, the wire harness segment directly connected to the test head drives the rotating portion of the anti-tangle assembly to rotate synchronously. Due to the constraint of the limiting space, the main body of the tubing bundle assembly only makes a small-angle arc-shaped oscillation with the rotating portion, avoiding circumferential twisting and entanglement caused by superposition, thus cutting off the conditions for entanglement from the perspective of the motion trajectory.

Description

Technical Field

[0001] This invention relates to the field of testing technology, and more specifically to a testing device. Background Technology

[0002] In existing technologies, testing devices are driven by motors to move up and down and rotate, thereby enabling various testing functions on target objects, such as PCBs. The cable bundle is connected to one end of the test head and extends upward to connect to the display device. During the up-and-down and rotational movements, especially during rotation, the cable bundle hangs freely as the test head rotates. During rotation, the cable bundle naturally twists and overlaps along the circumference of the testing device, eventually forming entanglement. This causes the wire harness inside the cable bundle to easily break, affecting the overall testing and display effects. Furthermore, due to repeated entanglement and pulling, the outer sheath of the cable bundle ages faster, and the fatigue life of the internal wire harness is significantly shortened, usually requiring frequent shutdowns for replacement. This not only increases consumable costs but also reduces the effective testing time of the entire device. Summary of the Invention

[0003] In view of this, the present invention provides a testing device to solve the problem that the pipeline package is prone to entanglement when the testing device moves in the prior art.

[0004] This invention provides a testing device, including a base, a tubing assembly, and an anti-tangle component. A test head is rotatably mounted at the bottom of the base. The tubing assembly is located on one side of the base and contains a wire harness. One end of the wire harness is connected to the test head, which can drive the tubing assembly to rotate. The anti-tangle component is located at the top of the base and has a limiting space for bending the tubing assembly. The anti-tangle component is connected to the tubing assembly, and when the test head drives the tubing assembly to rotate, a portion of the anti-tangle component rotates synchronously.

[0005] In this application, the anti-winding component is located on the top of the base. Its limiting space forces the cable bundle assembly to be arranged in a bent state. At the same time, the anti-winding component is connected to the cable bundle assembly and rotates synchronously with the test head. When the test head rotates, the wire harness segment directly connected to the test head drives the rotating part of the anti-winding component to rotate synchronously. Due to the constraint of the limiting space, the main body of the cable bundle assembly only swings in a small arc angle with the rotating part, avoiding circumferential torsion and superposition that would lead to entanglement. This cuts off the conditions for entanglement from the perspective of motion trajectory, reduces friction and wear on the outer sheath of the cable bundle assembly and fatigue damage to the wire harness, and extends the replacement cycle of the cable bundle. At the same time, it avoids signal path interruption caused by copper core breakage of the wire harness, reduces signal interference and short circuit risk caused by outer sheath wear, and ultimately ensures that the PCB test data collected by the test head can be transmitted to the display device without loss or delay, and the accuracy of the test results and the stability of the display effect are continuously guaranteed.

[0006] In one alternative embodiment, one end of the anti-winding component extends upward along the height of the base, and the anti-winding component is provided with a support portion extending in the X direction to form a limiting space.

The connecting rod is disposed along the height direction of the pedestal. A limiting space is formed between the connecting rod and the support. A portion of the pipeline package assembly overlaps the support and extends along the direction of the connecting rod, causing the pipeline package assembly to be bent.

[0008] In one alternative embodiment, the extension direction of the support is set at a preset angle to the extension direction of the connecting rod.

[0009] In one optional embodiment, the top of the base is provided with a connecting shaft, and the support part includes a bearing, a first support member, and a second support member. The bearing is arranged circumferentially along the connecting shaft, a portion of the first support member is arranged circumferentially along the bearing, and one end of another portion of the first support member extends in the X direction. The second support member is located on the first support member and is connected to the first support member. The connecting rod is located on the second support member.

[0010] In one alternative implementation, the connecting rod is detachably connected to the support.

[0011] In one alternative embodiment, the second support includes a chassis and a connecting column located on the chassis. The chassis is fixed to the first support by a connector. The connecting column is formed by two semicircular blocks joined together and connected by a connector. A receiving groove for accommodating the connecting rod is formed between the two semicircular blocks.

[0012] In one optional embodiment, the pipeline package assembly includes a first pipeline package and a second pipeline package. The bottoms of both the first and second pipeline packages are located on one side of the base and are arranged adjacent to each other. The top of the first pipeline package is located in the limiting space and extends along the height direction of the anti-winding component. The top of the second pipeline package is bent toward the side away from the first pipeline package.

[0013] In one optional embodiment, the base includes a base body, a drive member, and a connecting plate. The base body is movably disposed along the height direction. An anti-winding component is disposed on the top of the base body. The drive member is located inside the base body and its output shaft is connected to the test head. The connecting plate is located at the bottom of the base body and is connected to the base body. The test head is disposed at the bottom of the connecting plate. The output shaft of the drive member can pass through the connecting plate and connect to the test head.

[0014] In one alternative embodiment, a limiting portion is provided on one side of the connecting plate, through which the pipeline assembly can be installed. Attached Figure Description

[0022] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0023] According to an embodiment of the present invention, a testing device is provided, including a base 10, a tubing assembly 20, and an anti-winding component 30. A test head 11 is provided at the bottom of the base 10 and is rotatably mounted. The tubing assembly 20 is located on one side of the base 10 and contains a wire harness 21. One end of the wire harness 21 is connected to the test head 11, which can drive the tubing assembly 20 to rotate. The anti-winding component 30 is disposed at the top of the base 10 and has a limiting space 31 for bending the tubing assembly 20. The anti-winding component 30 is connected to the tubing assembly 20, and when the test head 11 drives the tubing assembly 20 to rotate, a portion of the anti-winding component 30 rotates synchronously.

[0024] In this application, the anti-winding component 30 is disposed on the top of the base 10. Its limiting space 31 forces the cable bundle assembly 20 to be arranged in a bent state. At the same time, the anti-winding component 30 is connected to the cable bundle assembly 20 and rotates synchronously with the test head 11. When the test head 11 rotates, the wire harness segment directly connected to the test head 11 drives the rotating part of the anti-winding component 30 to rotate synchronously. Due to the constraint of the limiting space, the main body of the cable bundle assembly 20 only swings in a small arc with the rotating part, and does not undergo circumferential twisting and superposition. This cuts off the conditions for winding from the motion trajectory level, reduces the friction and wear of the outer sheath of the cable bundle assembly 20 and the fatigue damage of the wire harness, and extends the replacement cycle of the cable bundle. At the same time, it avoids the interruption of the signal path caused by the copper core breakage of the wire harness, reduces the signal interference and short circuit risk caused by the wear of the outer sheath, and ultimately ensures that the PCB test data collected by the test head can be transmitted to the display device without loss and delay, and the accuracy of the test results and the stability of the display effect are continuously guaranteed.

[0025] Specifically, this application achieves active constraint against entanglement through two structural features: the limiting space 31 of the anti-entanglement component 30 and partial synchronous rotation. The principle is as follows: The limiting space 31 of the anti-winding component forces the pipeline bundle assembly 20 into a fixed bent shape. This bent structure is equivalent to setting a rigid fulcrum on the extension path of the pipeline bundle. From a mechanical point of view, the stress distribution at the bend will change abruptly. The torque generated by the rotation of the test head 11, when transmitted to the bend, will be mostly offset by the supporting reaction force of the bend structure and cannot continue to be transmitted upward along the pipeline bundle assembly 20. This cuts off the channel for torque to diffuse to the pipeline bundle assembly 20 in the force transmission path, preventing the pipeline bundle body from circumferentially torturing due to torque.

[0026] Furthermore, the anti-winding component 30 is connected to the cable bundle assembly 20, and a portion of the anti-winding component rotates synchronously when the test head 11 rotates. The rotational angular velocity of this synchronously rotating part is completely consistent with that of the test head. Since this rotating part rotates at the same speed and in the same direction as the test head 11, there is no relative displacement between them. Therefore, the cable harness segment directly connected to the test head 11 only rotates coaxially with the rotating part and will not be subjected to additional tensile force. The main body of the cable bundle assembly 20, constrained by the limiting space 31, will only swing in a small arc with the rotating part. The swing amplitude is much smaller than the amplitude of the circumferential rotation, and there is no torsional action. The movement trajectory limits the range of motion of the cable bundle assembly 20, avoiding the possibility of circumferential superimposed entanglement.

[0027] In one embodiment, one end of the anti-winding component 30 extends upward along the height of the base 10, and the anti-winding component 30 is provided with a support portion 33 extending in the X direction to form a limiting space 31.

[0028] It should be noted that the X direction is the horizontal direction of the base 10, that is, the support part 33 extends horizontally toward the side away from the base 10.

[0029] The anti-winding component 30 extends upwards along the height of the base 10, without occupying the testing space below the base 10, thus avoiding interference with the handling and testing of target objects such as PCBs. The support part 33 extends in the X direction, and the lateral span of the limiting space 31 can be flexibly adjusted according to the arrangement position of the cable bundle assembly 20 to adapt to the cable bundle layout requirements of different models. At the same time, the X-direction extending support part 33 provides a stable support base for the cable bundle assembly 20. Combined with the height-extended anti-winding component 30, it forces the cable bundle assembly 20 to form a bending shape with lateral support and vertical extension, structurally fixing the bending angle and preventing the cable bundle assembly 20 from shifting its bending shape due to its own weight or equipment vibration, thus ensuring the stability of the torque isolation effect.

[0030] In one embodiment, the anti-winding component 30 further includes a base 32 and a connecting rod 34. The base 32 is located on the base 10, and the support part 33 is located on the base 32. The support part 33 is rotatably disposed relative to the base 32. One end of the support part 33 extends along the X direction. The connecting rod 34 is located on the support part 33 and is connected to the support part 33. The connecting rod 34 is disposed along the height direction of the base 10. A limiting space 31 is formed between the connecting rod 34 and the support part 33. A portion of the pipeline package 20 overlaps the support part 33 and extends along the direction of the connecting rod 34, so that the pipeline package 20 is bent.

[0031] The support part 33 is rotatable relative to the base 32. When the test head 11 rotates, the support part 33 can rotate synchronously with the rotation of the pipeline package assembly 20, ensuring that the rotational angular velocity is consistent with that of the test head 11, eliminating the relative displacement tension between the support part 33 and the pipeline package assembly 20, and further reducing stress damage to the wire harness.

[0032] The design of the pipeline package assembly 20 overlapping the support part 33 ensures that the bending point of the pipeline package assembly 20 fits snugly with the support part 33, preventing the pipeline package assembly 20 from sliding or shifting during rotation; at the same time, the connecting rod 34 extends along the height direction to guide the vertical extension section of the pipeline package assembly 20. The double constraint ensures that the pipeline package assembly 20 is always in the preset bending trajectory, making the anti-winding effect more stable.

[0033] It should be noted that the pipeline package assembly 20 and the connecting rod 34 are bound together by a connector, which can be made of wire harness strips, etc. The number of wire harness strips is not limited to one; it can be two, three, etc.

[0034] In one embodiment, the extension direction of the support 33 is set at a preset angle to the extension direction of the connecting rod 34.

[0035] In this embodiment, the extending direction of the support 33 is at 90° to the extending direction of the connecting rod 34, i.e., the preset angle is 90°. In other embodiments, the connecting rod 34 can be tilted so that the preset angle is 70°, 80°, 120°, etc.

[0036] The preset angle can be specifically designed according to the material, diameter, length, and other parameters of the cable bundle assembly 20. For example, a 90° right angle is suitable for short cable bundles, and an obtuse angle is suitable for long cable bundles. By adjusting the bending angle, the stress distribution at the bending point of the cable bundle is optimized, avoiding local stress concentration caused by excessively large or small bending angles, and further extending the service life of the cable harness. Different models of testing devices have different cable bundle layout paths and lengths. The preset angle design enables standardized production and differentiated adaptation of the anti-winding assembly 30, eliminating the need to redesign the overall structure for different models and reducing R&D costs.

[0037] In one embodiment, the base 32 has a connecting shaft 321 on its top, and the support part 33 includes a bearing 331, a first support member 332, and a second support member 333. The bearing 331 is arranged circumferentially along the connecting shaft 321, a portion of the first support member 332 is arranged circumferentially along the bearing 331, and one end of another portion of the first support member 332 extends in the X direction. The second support member 333 is located on the first support member 332 and is connected to the first support member 332. The connecting rod 34 is located on the second support member 333.

[0038] On the one hand, the cooperation between bearing 331 and connecting shaft 321 transforms the rotational friction of support 33 from sliding friction to rolling friction, significantly reducing rotational resistance and preventing pipeline pulling and twisting caused by rotational jamming of support 33, thus ensuring the smooth synchronous rotation of anti-entanglement component 30 during the rotation of test head 11. The first support member 332 has a bearing-encircling section and an X-direction extension section, which not only ensures rotational coaxiality but also improves the structural rigidity of support 33; the second support member 333 independently supports connecting rod 34, realizing layered force transmission, preventing the load of connecting rod 34 from directly acting on the rotating parts, and extending the service life of the rotating structure.

[0039] On the other hand, the precise fit between the bearing 331 and the connecting shaft 321 limits the rotational deviation of the support part 33, ensuring that the rotation axis of the support part 33 and the test head 11 are consistent, and avoiding excessive swing amplitude of the pipeline package due to eccentric rotation.

[0040] In one embodiment, the connecting rod 34 is detachably connected to the support portion 33.

[0041] When the connecting rod 34 is worn, deformed, or needs to be changed in size, it can be disassembled separately without replacing the entire anti-winding assembly 30, reducing maintenance costs and downtime for repairs. Furthermore, connecting rods 34 of different diameters and materials can be replaced according to actual needs. For example, thicker connecting rods are suitable for multi-wire harness coils, and wear-resistant connecting rods are suitable for high-frequency rotation scenarios, thus upgrading the functionality of the anti-winding assembly 30.

[0042] In one embodiment, the second support member 333 includes a chassis 3331 and a connecting column 3332 located on the chassis 3331. The chassis 3331 is fixed to the first support member 332 by a connector. The connecting column 3332 is formed by two semicircular blocks joined together and connected by a connector. A receiving groove 3333 for receiving the connecting rod 34 is formed between the two semicircular blocks.

[0043] The receiving groove 3333 formed by the two semi-circular blocks can accurately wrap the connecting rod 34, preventing the connecting rod from radially shifting during equipment operation and ensuring the stability of the limiting space; at the same time, the modular structure allows for the assembly and disassembly of the connecting rod without disassembling other parts, making the operation simple and requiring no special tools.

[0044] Furthermore, by replacing the modular connecting posts with different inner diameters, connecting rods of different diameters can be adapted, further improving the versatility of the anti-winding assembly 30 and reducing spare parts inventory costs.

[0045] In one embodiment, the cable bundle assembly 20 includes a first cable bundle 22 and a second cable bundle 23. The bottoms of the first cable bundle 22 and the second cable bundle 23 are both located on one side of the base 10 and are arranged adjacent to each other. The top of the first cable bundle 22 is located at the limiting space 31 and extends along the height direction of the anti-winding assembly 30. The top of the second cable bundle 23 is bent toward the side away from the first cable bundle 22.

[0046] For multi-wire harness testing devices, the two wire bundles are arranged separately. The first wire bundle 22 is constrained by the anti-tangle component 30, while the second wire bundle 23 is bent independently. This avoids the two wire bundles from tangling and rubbing against each other during rotation, solving the tangling problem in multi-wire bundle layouts. The two wire bundles are arranged adjacently with differentiated bends, making full use of the unused space on one side of the base 10 and avoiding space congestion caused by messy wire bundle arrangement, thus facilitating subsequent inspection and maintenance.

[0047] In one embodiment, the base 10 includes a base 12, a drive member 13, and a connecting plate 14. The base 12 is movably disposed along the height direction. An anti-winding component 30 is disposed on the top of the base 12. The drive member 13 is located inside the base 12, and the output shaft of the drive member 13 is connected to the test head 11. The connecting plate 14 is located at the bottom of the base 12 and is connected to the base 12. The test head 11 is disposed at the bottom of the connecting plate 14, and the output shaft of the drive member 13 can pass through the connecting plate 14 and connect to the test head 11.

[0048] The base 12 can move along the height direction, driving the anti-winding component 30 at the top to rise and fall synchronously. This ensures that the tubing bundle is always under the limiting constraint of the anti-winding component during the up-and-down movement of the test head 11, preventing the tubing bundle from deviating from the bending trajectory due to rising and falling. This achieves full anti-winding coverage in both rotation and rising / falling modes. The drive component 13 is built into the base 12, saving external space of the base 10. The connecting plate 14 centrally supports the test head 11, making the layout of the test head 11, drive component 13, and anti-winding component 30 more regular and reducing the overall size of the equipment.

[0049] It should be noted that a device for controlling the up and down movement is provided on the side of the base 10 away from the pipeline package assembly 20, including components such as a lifting motor, coupling, and guide slider, so as to realize the up and down movement of the test head 11 driven by the base 10 in the height direction. The specific structure of this part will not be described or shown here.

[0050] In one embodiment, a limiting part 141 is provided on one side of the connecting plate 14, through which the pipeline package assembly 20 can be disposed.

[0051] The limiting part 141 positions the lower end of the pipeline package and forms a double constraint with the anti-winding component 30 at the upper end, preventing the lower end of the pipeline package from swinging or shifting significantly when the test head 11 rotates, and further limiting the range of motion of the pipeline package.

[0052] In this embodiment, the limiting part 141 is a fixing member with openings on three sides, allowing the pipeline package assembly 20 to pass through the limiting part 141. In other embodiments, the limiting part 141 may also be a cylindrical structure with through holes.

[0053] On the other hand, this application also provides a flying probe tester, including the test apparatus of the above embodiments.
