Description

Technical Field

[0001] This utility model relates to the field of electronic product assembly and fastening technology, and in particular to a bracket assembly and screw fastening device. Background Technology

[0002] Currently, the assembly and attachment of CPU brackets to motherboards in electronic products mainly involves manual alignment of the CPU bracket with the motherboard by operators. This ensures the holes on the bracket align with those on the motherboard, and a screwdriver is used to insert screws through the holes on the bracket and into the screw holes on the motherboard, gradually tightening the screws to ensure a tight fit. However, over-tightening can damage the screws or deform the motherboard. However, visually aligning the screws and screw holes cannot guarantee perfect alignment; angular misalignment may occur, causing the screws to be misaligned, resulting in stripped threads or motherboard damage. Furthermore, manual attachment of the CPU bracket to the motherboard is prone to over-tightening or under-tightening. Over-tightening can deform the motherboard, while under-tightening can cause the CPU bracket to detach from the motherboard. Utility Model Content

[0028] Before describing the embodiments of this utility model in detail, the application environment of this utility model will be described first. The technology of this utility model is mainly applied to the field of electronic product assembly and fastening technology. This utility model is used to solve the problems of screw misalignment, excessively tight or loose screw fastening during the existing manual assembly and fastening operations of CPU brackets and motherboards.

[0029] Please combine Figures 1 to 4 As shown, this utility model provides a bracket assembly and screw-locking device.

[0030] In an exemplary embodiment of this application, the bracket assembly and screw-locking device includes: a frame 1, on which a rack 101 for storing brackets 102 to be locked is provided; a conveying mechanism 2, disposed on the frame 1, for transporting a tray 201 loaded with a motherboard; a transfer, extraction, and locking mechanism, disposed on the frame 1, including a transfer module 3, an extraction module 4, and a locking module 5, wherein the extraction module 4 is used to extract the brackets 102 to be locked from the rack 101 and assemble them with the motherboard, the locking module 5 is used to lock the brackets 102 to be locked to the motherboard, and the transfer module 3 is used to drive the extraction module 4 and the locking module 5 to move; a vision module 6, disposed on the frame 1, for identifying the assembly position and locking hole position of the brackets 102 to be locked to the motherboard; and a pressing and positioning mechanism 7, disposed on the frame 1, for pressing and positioning the brackets 102 to be locked onto the motherboard.

[0031] In this embodiment, the transfer module 3 drives the extraction module 4 to move to the material rack 101 to extract the bracket 102 to be locked. The vision module 6 identifies the assembly position of the bracket 102 to be locked on the motherboard. Then, the transfer module 3 drives the extraction module 4 to move to the motherboard to assemble the bracket 102 to be locked with the motherboard. After assembly, the pressing and positioning mechanism 7 presses and positions the bracket 102 to be locked on the motherboard, providing pre-tightening force to prevent displacement of the bracket 102 to be locked with the motherboard. After pressing and positioning, the vision module 6 identifies the locking hole positions of the bracket 102 to be locked with the motherboard. After the locking hole positions are determined, the transfer module 3 drives the locking module 5 to move to the motherboard to lock and fix the bracket 102 to be locked with the motherboard. This application uses the fastening module 5 to perform the fastening operation between the bracket 102 to be fastened and the motherboard, which can fasten the screws within the preset tightening torque, avoiding the problem of the screws being too tight or too loose; the pressing and positioning mechanism 7 presses and positions the bracket 102 to be fastened on the motherboard, and the vision module 6 identifies the fastening hole positions of the bracket 102 to be fastened and the motherboard, effectively avoiding the problem of the screws being misaligned between the component to be fastened and the motherboard.

[0032] It is worth noting that the conveying mechanism 2 is a motor-driven chain conveyor, and the frame 1 is equipped with a blocking cylinder. The blocking cylinder is used to block and position the material tray 201 at the assembly and locking station. The frame 1 is also equipped with a lifting mechanism, which is used to lift the material tray 201 away from the conveying mechanism 2. The transfer module 3 is a robotic arm module, and the locking module 5 is a self-locking screw machine.

[0033] In an exemplary embodiment of this application, the extraction module 4 includes an extraction driving component 401 and an extraction component 402. The extraction driving component 401 is used to drive the extraction component 402 to move along the height direction of the frame 1. The extraction component 402 is provided with a through hole 402a, which is used to pass through the material rack 101.

[0034] In this embodiment, the extraction drive component 401 is a cylinder, the material rack 101 is an I-shaped steel, and the bracket to be locked 102 is stacked and sleeved on the material rack 101 along the length direction of the material rack 101. By providing a through hole 402a on the extraction component 402, the extraction component 402 can be quickly positioned with the material rack 101 and the bracket to be locked 102 on the material rack 101 can be extracted.

[0035] In an exemplary embodiment of this application, the extraction component 402 is provided with a plurality of suction cups 402b around the through hole 402a, and the suction cups 402b are used to adsorb the support 102 to be locked on the extraction material rack 101.

[0036] In this embodiment, the through hole 402a is a rectangular hole, and the extraction component 402 is provided with four suction cups 402b around the through hole 402a. The suction cups 402b are connected to the negative pressure component, and the extraction component 402 extracts the bracket 102 to be locked by adsorption.

[0037] In an exemplary embodiment of this application, the extraction component 402 is further provided with an extraction positioning post 402c, which is used to cooperate with the locking hole of the bracket 102 to be locked.

[0038] In this embodiment, two extraction positioning posts 402c are provided on the extraction component 402 at a pair of diagonal positions of the through hole 402a. By cooperating with the locking hole of the bracket 102 to be locked by the extraction positioning posts 402c, the posture of the bracket 102 to be locked extracted by the extraction component 402 is determined on the extraction component 402, avoiding secondary adjustment of the assembly angle between the bracket 102 to be locked and the motherboard.

[0039] In an exemplary embodiment of this application, the frame 1 is further provided with a hopper 103 and a vision inspection module 104. The hopper 103 is used to store screws, and the vision inspection module 104 is used to detect the posture of the screws extracted from the fastening module 5.

[0040] In this embodiment, the visual inspection module 104 detects whether the screw angle extracted by the fastening module 5 from the hopper 103 is in a vertical state. If the screw angle is deviated, the screw is thrown out, thereby ensuring that the screw is in a vertical state for fastening the bracket 102 and the motherboard, and avoiding screw misalignment.

[0041] In an exemplary embodiment of this application, a linear transfer bracket 8 is provided on the frame 1. The linear transfer bracket 8 is provided with a first linear transfer mechanism 801 and a second linear transfer mechanism 802 along the height direction. The vision module 6 is disposed on the first linear transfer mechanism 801. The first linear transfer mechanism 801 is used to drive the vision module 6 to move along the width direction of the conveying mechanism 2. The pressing and positioning mechanism 7 is disposed on the second linear transfer mechanism 802. The second linear transfer mechanism 802 is used to drive the pressing and positioning mechanism 7 to move along the width direction of the conveying mechanism 2.

[0042] In this embodiment, both the first linear transfer mechanism 801 and the second linear transfer mechanism 802 are motor-driven screw transmission devices. The first linear transfer mechanism 801 and the second linear transfer mechanism 802 are offset along the height direction of the transfer bracket. When identifying the assembly position of the bracket to be locked 102 and the motherboard, the second linear transfer mechanism 802 drives the pressing positioning mechanism 7 to move along the width direction of the conveying mechanism 2 to avoid the pressing positioning mechanism 7 interfering with the recognition result of the vision module 6. Since two brackets to be locked 102 need to be assembled on the motherboard, the first linear transfer mechanism 801 drives the vision module 6 to move along the width direction of the conveying mechanism 2 to satisfy the recognition of the two assembly positions.

[0043] In an exemplary embodiment of this application, the vision module 6 includes a telescopic drive component 601 and a vision module 602. The telescopic drive component 601 is used to drive the vision module 602 to move along the length direction of the conveying mechanism 2.

[0044] In this embodiment, the telescopic drive component 601 is a telescopic cylinder, and the vision module 602 is a CCD camera. The telescopic drive component 601 drives the vision module 602 to move along the length direction of the conveying mechanism 2 to identify the locking holes on the bracket 102 to be locked and the motherboard at different positions along the length direction of the conveying mechanism 2.

[0045] In an exemplary embodiment of this application, the pressing positioning mechanism 7 includes a lifting drive component 701 and a pressing component 702. The lifting drive component 701 is used to drive the pressing component 702 to move along the height direction of the linear transfer bracket 8.

[0046] In this embodiment, the lifting drive component 701 is a telescopic cylinder. The lifting drive component 701 drives the pressing component 702 to move along the height direction of the linear transfer bracket 8, so that the pressing component 702 can press and position the bracket 102 to be locked on the material tray 201 that has been assembled with the main board, thus preventing the bracket 102 to be locked from shifting from the main board.

[0047] In an exemplary embodiment of this application, the pressing component 702 is provided with a pressing positioning post 702a, which is used to cooperate with the locking holes of the bracket 102 to be locked and the main board.

[0048] In this embodiment, two pressing positioning posts 702a are provided diagonally along the upper edge of the pressing component 702. The pressing component 702a is used to quickly position the pressing component 702 with the locking hole. The locking component first locks the two locking holes without positioning posts to ensure that the bracket 102 to be locked will not be offset from the motherboard. At this time, the pressing action of the pressing component 702 on the bracket 102 to be locked can be removed, and then the remaining two screws can be locked.

[0049] In one exemplary embodiment of this application, the pressing member 702 is provided with a cushioning pad 702b.

[0050] In this embodiment, the buffer pad 702b includes, but is not limited to, flexible materials such as rubber, to avoid the problem of deformation of the bracket 102 caused by direct contact between the rigid material of the pressing component 702 and the bracket to be locked.

[0051] The working principle is as follows: the transfer module 3 drives the extraction module 4 to move to the material rack 101 to extract the bracket 102 to be locked. The vision module 6 identifies the assembly position of the bracket 102 and the motherboard on the motherboard. Then, the transfer module 3 drives the extraction module 4 to move to the motherboard to assemble the bracket 102 and the motherboard. After assembly, the pressing and positioning mechanism 7 presses and positions the bracket 102 on the motherboard to provide pre-tightening force to prevent the bracket 102 and the motherboard from shifting. After pressing and positioning, the vision module 6 identifies the locking hole positions of the bracket 102 and the motherboard. After the locking hole positions are determined, the transfer module 3 drives the locking module 5 to move to the motherboard to lock and fix the bracket 102 and the motherboard. This application uses the fastening module 5 to perform the fastening operation between the bracket 102 to be fastened and the motherboard, which can fasten the screws within the preset tightening torque, avoiding the problem of the screws being too tight or too loose; the pressing and positioning mechanism 7 presses and positions the bracket 102 to be fastened on the motherboard, and the vision module 6 identifies the fastening hole positions of the bracket 102 to be fastened and the motherboard, effectively avoiding the problem of the screws being misaligned between the component to be fastened and the motherboard.

[0052] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
