Description

Technical Field

[0001] This utility model relates to the field of substrate inspection technology, and in particular to a substrate inspection fixture rotation and conveying device. Background Technology

[0002] In the field of electronics manufacturing, printed circuit boards (PCBs), which are the core carriers of electronic devices, need to have their electrical performance and structural reliability verified by specialized testing fixtures. In traditional testing systems, testing fixtures are set on both the upper and lower sides of the testing station, with the upper and lower testing fixtures facing each other. After pressing, the high-density probe array on the fixtures makes reliable contact with the substrate pads to complete key tests such as conductivity, insulation resistance, and signal integrity.

[0003] As electronic products rapidly evolve towards higher complexity and integration, substrate sizes have exceeded 550mm × 650mm, leading to a significant increase in the volume and weight of corresponding inspection fixtures. In actual production line applications, inspection fixtures need to be transferred from the storage area to the inspection station. During the installation and positioning phase, the upper inspection fixture must be rotated 180° to achieve installation. However, handling and rotating large fixtures is inconvenient, resulting in low handling efficiency and a risk of heavy fixtures falling, which can easily cause equipment damage and personnel injury. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a substrate inspection fixture rotation and handling device, which can smoothly complete the handling and flipping operations of large fixtures, simplifying the loading and unloading of large fixtures.

[0005] Therefore, the technical solution of this utility model is: a substrate testing fixture rotation and transportation device, including a transportation trolley and a fixture fixing fixture, wherein the transportation trolley is provided with a hydraulic lifting seat and a rotatable rotating bracket is installed on the hydraulic lifting seat;

[0006] The fixture fixing tool is mounted on the rotating bracket, and the fixture fixing tool has sliding grooves on both sides for inserting the fixture; the fixture fixing tool is provided with a locking assembly, which includes a locking block, and the locking block is located on the side away from the rotating bracket.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the locking assembly further includes a push rod, one end of which is connected to the operating handle near the rotating bracket, and the other end of which is connected to the locking block; the locking block is provided with an L-shaped locking surface, and the push rod can drive the locking block to move up or down, that is, the L-shaped locking surface has two states: abutting against the edge of the fixture and disengaging from the edge of the fixture.

[0008] Based on the above solution and as a preferred embodiment of the above solution: the locking assembly further includes a locking block mounting base, which has a vertical guide groove; the locking block has inclined grooves on both sides, and a C-shaped bracket is fixed at the end of the push rod, with a pulley that slides with the inclined groove on the inner side of the C-shaped bracket; the push rod pushes the pulley to move along the inclined groove, thereby driving the locking block to move up and down along the guide groove.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: when the locking block is in the lowest position, the locking block does not interfere with the lower surface of the fixture.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the fixture fixing tool is provided with multiple sets of parallel locking components, and different locking blocks are located at different positions of the fixture fixing tool.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: a guide limiting block is provided at the entrance of the chute, and a vertically arranged spring is provided on the back of the guide limiting block; a horn-shaped opening is provided on the side of the guide limiting block, and the horn-shaped opening is opposite to or higher than the entrance of the chute.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the slide groove is provided with a limiting block at one end near the rotating support, and the upper and lower surfaces of the slide groove are provided with rollers.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: the hydraulic lifting seat is equipped with a rotary motor, and the rotary bracket is fixed on the output shaft of the rotary motor, which can drive the fixture fixing tool to rotate 180 degrees.

[0014] Based on the above scheme and as a preferred embodiment of the above scheme: the transport trolley is equipped with a hydraulic power mechanism that can drive the hydraulic lifting seat to move up and down.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The fixture is locked and clamped by the fixture fixing tool. Through the coordinated action of the hydraulic lifting seat and the rotary motor, the heavy-duty inspection fixture is lifted and rotated smoothly and accurately. The 180° automatic rotation mechanism of the rotating bracket completely replaces manual handling, fundamentally avoiding the risk of fixture falling. It ensures the safety of operators and significantly improves the efficiency of large tooling transfer.

[0017] 2. The testing fixture is fixed by using the sliding grooves on both sides of the fixture, and the locking block is driven by the push rod linkage to lock the testing fixture, preventing the testing fixture from slipping during transportation and flipping. At the same time, the locking block can be raised and lowered under the action of the push rod, which not only ensures that the testing fixture is restricted in the locked state, but also completely avoids the bottom surface of the testing fixture when unlocking, so as to achieve interference-free loading and unloading.

[0018] 3. The guide limit block at the chute inlet is matched with the horn-shaped opening, and a spring is provided below the guide limit block. During the process of the fixture sliding in, the horn-shaped opening is opposite to the position of the chute inlet, which can guide the fixture to slide accurately into the chute. After the fixture has completely slid into the chute, the guide limit block moves upward under the action of the spring, which plays a certain blocking role and restricts the fixture from sliding out of the chute.

[0019] 4. Locking blocks at different positions are set on the fixture fixing tool to adapt to different specifications of fixtures and improve the versatility of the device. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0031] See the attached drawings. The substrate inspection fixture rotation and transport device described in this embodiment includes a transport trolley 1 and a fixture fixing fixture 2. The transport trolley 1 has a base frame 11 and a column 12. The base frame 11 is equipped with rollers 13 to facilitate the movement of the transport trolley 1. The column 12 is equipped with a hydraulic lifting seat 14 and a hydraulic power mechanism 15, which drives the hydraulic lifting seat 14 to move up and down. The hydraulic power mechanism can be a commercially available electric hydraulic lifting mechanism to complete the lifting of the hydraulic lifting seat.

[0032] The hydraulic lifting seat 14 is provided with a motor box 16, and a rotary motor is provided inside the motor box. A rotary bracket 17 is fixed on the output shaft of the rotary motor. A fixture fixing tool 2 is installed on the rotary bracket 17. The rotary motor can drive the fixture fixing tool 2 to rotate 180 degrees through the rotary bracket 17.

[0033] The fixture fixing fixture 2 is used to install the substrate testing fixture (hereinafter referred to as "fixture 3"). The fixture fixing fixture 2 has sliding grooves 21 on both sides for inserting the fixture. Rollers 22 are provided on the upper and lower groove surfaces of the sliding grooves 21 to facilitate the movement of the fixture 3 along the sliding grooves 21 and reduce friction. A limiting block 23 is provided at one end of the sliding groove 21 near the rotating bracket 17 to limit the position of the fixture 3 and prevent it from sliding out from the other side of the sliding groove 21.

[0034] A guide limiting block 4 is provided at the entrance of the slide 21, and a vertically arranged spring 41 is provided on the back of the guide limiting block 4; a flared opening 42 is provided on the side of the guide limiting block 4, which is opposite to or higher than the entrance of the slide 21. During the sliding of the fixture 3, the fixture 3 presses down on the guide limiting block 4, causing the flared opening 42 to move down to be opposite to the entrance of the slide 21, which can guide the fixture 3 to slide accurately into the slide 21; after the fixture 3 has completely slid into the slide 21, the guide limiting block 4 moves upward under the action of the spring 41, which can prevent the fixture 3 from sliding out of the slide 21.

[0035] The fixture fixing tool 2 is provided with at least one set of locking components 5. If multiple sets of parallel locking components 5 are provided, and different locking blocks 51 are located at different positions of the fixture fixing tool 2, fixtures 3 of different specifications can be clamped and locked.

[0036] The locking assembly 5 includes a locking block 51, a push rod 52, an operating handle 53, and a locking block mounting base 54. The end of the push rod 52 near the rotating bracket 17 is connected to the operating handle 53, and a slider 55 is provided on the push rod 52. A slide rail 24 is provided on the fixture fixing tool 2, and the operating handle 53 can drive the push rod 52 to move along the slide rail 24. The end of the push rod 52 away from the rotating bracket 17 is connected to an U-shaped bracket 56, and pulleys 5 are provided inside both sides of the U-shaped bracket 56. 7; The locking block 51 has inclined grooves 58 on both sides, and the inclined grooves 58 are inclined upward towards the locking block mounting base 54. The pulley 57 on the inner side of the C-shaped bracket 56 is placed in the inclined groove 58, and the two slide in cooperation; The locking block mounting base 54 has a vertical guide groove 59, and the locking block 51 has a pin 510 on the side facing the locking block mounting base 54. The pin 510 is placed in the guide groove 59; The locking block 51 has an L-shaped locking surface 511 on the side facing the push rod 52.

[0037] When the operating handle 53 pushes the push rod 52 toward the lock block mounting base 54, the pulley 57 of the U-shaped bracket 56 moves within the inclined groove 58 of the lock block 51, causing the lock block 51 to move downwards along the guide groove 59, thus placing the lock block 51 at its lowest position. The lock block 51 does not interfere with the lower surface of the fixture 3, allowing the fixture 3 to be pushed normally. After the fixture 3 is in place, pulling the operating handle 53 backwards causes the push rod 52 to move the lock block 51 away from the lock block mounting base 54. The pulley 57 of the U-shaped bracket 56 then moves within the inclined groove 58, causing the lock block 51 to move upwards along the guide groove 59, thus moving the L-shaped locking surface 511 on the lock block 51 to its highest position, abutting against the edge of the fixture 3, thereby locking the fixture 3.

[0038] In use, fix the fixture 2 onto the rotating bracket 17, at which point all locking blocks 51 are in their lowest position. Then, push the fixture 3 into the slide groove 21 through the flared opening 42 of the guide limit block 4. At this point, the guide limit block 4 is pressed down by the fixture, and the spring 41 is compressed. When the front end of the fixture 3 abuts against the limit stop 23 of the slide groove 21, it indicates that the fixture 3 has moved to the bottom. At this point, the fixture 3 leaves the guide limit block 4, and the guide limit block 4 moves upward under the action of the spring 41, preventing the fixture 3 from sliding out of the slide groove 21. Then, according to the specifications of the fixture 2, lock the corresponding locking blocks 51. (Alternatively, the fixture fixing tool and the fixture can correspond one-to-one, with only one corresponding locking block; two locking blocks can also be set, such as...) Figure 4 As shown, depending on the usage requirements, the other idle locking block can be in the lowest position, without interfering with the normal loading and unloading of the fixture.

[0039] Move the transport trolley 1 to the side of the testing device, and move the fixture 3 to the side of the fixture mounting base of the testing device. If the fixture is installed, drive the rotating bracket 17 to rotate 180 degrees so that the fixture 3 faces down. If the fixture is installed without the fixture, the fixture 3 does not need to be flipped. Then, release the locking block 51 so that the locking block 51 is disengaged from the fixture 3. Then, align the slide groove 21 of the fixture fixing fixture 2 with the mounting slide groove of the fixture mounting base. The fixture mounting base is provided with a protrusion that can press down the guide limit block 4. The guide limit block 4 can be pressed down to facilitate pushing the fixture 3 directly into the mounting slide groove of the fixture mounting base, thereby completing the installation operation of the fixture 3.
