Technical Field

[0001] This utility model relates to the field of electronic component testing technology, and in particular to an automatic motherboard replacement device. Background Technology

[0002] In the mass production testing of PCB motherboards, frequent replacement and repositioning of the motherboard and daughterboard are required. The positioning accuracy after replacement directly determines the reliability of the motherboard and daughterboard connection. Once a positioning error occurs, it will lead to poor circuit contact, inaccurate test results, or even damage to precision electronic components during subsequent testing. During the positioning process, it is also necessary to avoid the deformation of the daughterboard under stress. This requires considering the insulation protection and support protection of the PCB board during the positioning process. Therefore, an automatic motherboard and daughterboard replacement device is needed to ensure the positioning accuracy and protection of the motherboard and daughterboard during the replacement process. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an automatic mother-daughter plate replacement device to solve the problem of positioning accuracy after mother-daughter plate replacement in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution: An automatic motherboard / daughterboard replacement device includes: A replacement base is provided, wherein an insulating plate seat is provided on the replacement base, and a liftable sub-plate support plate is provided on the upper side of the insulating plate seat. A positioning component is arranged between the insulating plate seat and the sub-plate support plate along the circumference of the insulating plate seat. The positioning component includes a guide slider that is slidably connected to the insulating plate base in the horizontal direction. A support plate slide is provided inside the guide slider. The support plate slide is arranged along the diagonal direction of the guide slider, and the side of the support plate slide near the sub-plate support plate is open. A slide entrance is provided at the highest point of the support plate slide. Support plate pulleys are provided along the circumferential side of the sub-plate support plate, and the support plate pulleys slide in cooperation with the support plate slide rails.

[0005] To achieve the above technical solution, the positioning component is used to perform positioning processing on the sub-plate support plate after replacement, thereby ensuring the positioning accuracy of the sub-plate after each replacement. The support plate slide is set along the diagonal direction of the guide slider, which allows the support plate pulley on the sub-plate support plate to slide within the support plate slide, realizing the lifting and lowering movement of the sub-plate support plate. The side of the support plate slide closest to the sub-plate support plate is set as an open design, which facilitates the sliding cooperation between the support plate pulley and the support plate slide, ensuring the stability of the lifting and lowering movement of the sub-plate support plate. The setting of the slide inlet can provide preliminary positioning processing for the support plate pulley, ensuring that the support plate pulley can slide stably within the support plate slide.

[0006] In one embodiment of the present invention, four sets of guide rails are arranged on the insulating plate base along its circumference, and a slider drive is arranged on two sets of parallel guide rails. The slider drive drives the guide slider to slide along the guide rails.

[0007] To achieve the above technical solution, setting four sets of guide rails can improve the synchronicity of the guide slider sliding along the guide rails and ensure the overall stability of the sub-plate support plate during lifting. Slider drive components are set on two sets of parallel guide rails, which can reduce the number of drive units while ensuring the stability of the drive.

[0008] In one embodiment of the present invention, a slider base plate is provided between the guide slider and the guide rail, the slider base plate and the guide rail are slidably engaged, and multiple sets of guide sliders are arranged on the slider base plate in the horizontal direction.

[0009] To achieve the above technical solution, the use of the slider base plate can improve the stability of the cooperation between the guide slider and the guide rail. Setting multiple sets of guide sliders can improve the overall stability of the sub-plate support plate during lifting and lowering, and avoid the problem of inaccurate positioning of the sub-plate support plate after replacement.

[0010] In one embodiment of this utility model, a lifting assembly for loading and unloading materials is also included.

The lifting drive component drives the support plate push plate to rise and lift the sub-plate support plate, so that the sub-plate support plate can slide on the push plate pulley to facilitate loading and unloading materials.

[0011] To achieve the above technical solution and reduce the risk of collision damage to the sub-plate and mother plate during loading and unloading, a lifting assembly is installed to lift the sub-plate support plate to a non-assembly work surface before replacement. The lifting drive is used to drive the support plate push plate to rise and lift the sub-plate support plate. At that time, the push plate pulley contacts the sub-plate support plate, allowing the sub-plate support plate to slide on the support plate push plate, thus avoiding collision damage to the sub-plate support plate.

[0012] In one embodiment of the present invention, the support plate push plate is provided in multiple groups equally distributed along the length direction of the sub-plate support plate, and the sub-plate support plate is provided with a push plate through groove, and the support plate push plate and the push plate through groove are slidably engaged.

[0013] To achieve the above technical solution, multiple sets of support plates and push plates are used to improve the sliding stability of the sub-plate support plate on the support plate and push plate. The push plate through groove can provide lifting space for the support plate and push plate, ensuring the stability of the support plate and push plate in use.

[0014] In one embodiment of the present invention, a support guide plate is provided on the support plate push plate, the support guide plate is slidably connected to the support plate push plate along the length direction of the sub-plate support plate, and a feeding guide wheel is provided on the top of the support guide plate for guiding the loading and unloading of the sub-plate support plate.

[0015] To achieve the above technical solution, the support guide plate can provide initial guidance for the sub-plate support plate, making it easier for the sub-plate support plate to enter the support surface of the support plate pusher plate, ensuring the stability of the sub-plate support plate during loading. The support guide plate can extend out of the support plate pusher plate in the horizontal direction, thereby improving the ease of loading the sub-plate support plate. The feeding guide wheel can guide the sub-plate support plate while avoiding scratches and bumps.

[0016] In one embodiment of the present invention, the supporting guide plate is located on one side of the sub-plate supporting plate, and a guide plate driving member is provided on the supporting plate push plate, with the supporting guide plate located at the movable end of the guide plate driving member.

[0017] To achieve the above technical solution, the support guide plate is set on one side of the sub-plate support plate, which can improve the guiding coverage of the support guide plate on the sub-plate support plate and improve the stability of the sub-plate support plate during loading and unloading.

[0018] As described above, the automatic replacement device for mother and daughter plates of this utility model has the following beneficial effects: The positioning component performs positioning processing on the daughter plate support plate after replacement, thereby ensuring the positioning accuracy of the daughter plate after each replacement; the support plate slide is set along the diagonal direction of the guide slider, enabling the support plate pulley on the daughter plate support plate to slide within the support plate slide, realizing the lifting and lowering movement of the daughter plate support plate; the support plate slide is set with an open design on the side of the support plate slide closest to the daughter plate support plate, facilitating the sliding cooperation between the support plate pulley and the support plate slide, ensuring the stability of the lifting and lowering movement of the daughter plate support plate; the setting of the slide inlet provides preliminary positioning processing for the support plate pulley, ensuring that the subsequent support plate pulley can slide stably within the support plate slide.

[0028] Please see Figures 1 to 6 This utility model provides an automatic replacement device for mother and daughter boards, including a replacement base 1, an insulating board seat 2 disposed on the replacement base 1, a liftable daughter board support plate 3 disposed on the upper side of the insulating board seat 2, and a positioning component disposed between the insulating board seat 2 and the daughter board support plate 3 along the circumference of the insulating board seat 2. The positioning component is used to perform positioning processing on the daughter board support plate 3 after replacement, thereby ensuring the positioning accuracy of the daughter board after each replacement.

[0029] The positioning component includes a guide slider 4 that is slidably connected to the insulating plate base 2 in a horizontal direction. A support plate slide 5 is provided inside the guide slider 4. The support plate slide 5 is arranged along the diagonal direction of the guide slider 4. The side of the support plate slide 5 closest to the sub-plate support plate 3 is open. A slide inlet 18 is provided at the highest point of the support plate slide 5. Support plate pulleys 6 are provided along the circumferential side of the sub-plate support plate 3. The support plate pulleys 6 slide and engage with the support plate slide 5. By arranging the support plate slide 5 along the diagonal direction of the guide slider 4, the support plate pulleys 6 on the sub-plate support plate 3 can slide within the support plate slide 5, thereby realizing the lifting and lowering movement of the sub-plate support plate 3.

[0030] When in use, place the sub-board support plate 3 on the insulating plate base 2, so that the support plate pulley 6 falls into the support plate slide 5. At that time, the support plate pulley 6 will move along the trajectory of the support plate slide 5, causing the sub-board support plate 3 to fall.

[0031] Setting the side of the support plate slide 5 closest to the sub-plate support plate 3 as open facilitates the sliding cooperation between the support plate pulley 6 and the support plate slide 5, ensuring the stability of the lifting and lowering movement of the sub-plate support plate 3. The setting of the slide inlet 18 can provide initial positioning for the support plate pulley 6, ensuring that the support plate pulley 6 can slide stably within the support plate slide 5.

[0032] Four sets of guide rails 7 are arranged around the insulating board base 2. A slider drive 8 is arranged on two parallel sets of guide rails 7. The slider drive 8 drives the guide slider 4 to slide along the guide rails 7. By setting four sets of guide rails 7, the synchronicity of the guide slider 4 sliding along the guide rails 7 can be improved, ensuring the overall stability of the sub-board support plate 3 during the lifting and lowering process. The slider drive 8 is arranged on two parallel sets of guide rails 7, which can reduce the number of drive units while ensuring the stability of the drive.

[0033] A slider base plate 9 is provided between the guide slider 4 and the guide slide rail 7. The slider base plate 9 and the guide slide rail 7 slide together. Multiple sets of guide sliders 4 are arranged on the slider base plate 9 in the horizontal direction. The slider base plate 9 can improve the stability of the cooperation between the guide slider 4 and the guide slide rail 7. Setting multiple sets of guide sliders 4 can improve the overall stability of the sub-plate support plate 3 during the lifting process and avoid the problem of inaccurate positioning of the sub-plate support plate 3 after replacement.

[0034] It also includes a lifting assembly for loading and unloading materials. The lifting assembly includes two sets of lifting base plates 10 symmetrically arranged on the lower side of the insulating plate base 2 and on the replacement base 1.

The lifting base plate 10 is provided with a lifting drive component 13. The lifting drive component 13 drives the support plate push plate 11 to rise and lift the sub-plate support plate 3, so that the sub-plate support plate 3 can slide on the push plate pulley 12 to facilitate loading and unloading. In order to reduce the collision damage to the sub-plate and the mother plate during the loading and unloading process, by setting up the lifting assembly, the sub-plate support plate 3 is lifted to the non-assembly working surface before replacement. The lifting drive component 13 drives the support plate push plate 11 to rise and lift the sub-plate support plate 3. At that time, the push plate pulley 12 contacts the sub-plate support plate 3, so that the sub-plate support plate 3 can slide on the support plate push plate 11, avoiding collision damage to the sub-plate support plate 3.

[0035] Multiple sets of support plate push plates 11 are evenly distributed along the length of the sub-plate support plate 3. Furthermore, the sub-plate support plate 3 is provided with a push plate through groove 14. The support plate push plates 11 and the push plate through groove 14 slide together.
