Description

Technical Field

[0001] This utility model relates to a PCBA housing handling fixture with MPO jumpers. Background Technology

[0002] In the optical module assembly process, PCBAs need to be transported and neatly arranged before being assembled into the housing. If the PCBA does not have an MPO installed before assembly, the assembly into the housing is relatively simple. However, the current process requires the MPO to be installed before assembly into the housing. The MPO and PCBA are often connected by jumpers, which is a flexible connection. If only the PCBA is picked up during transport, the MPO will sag due to gravity, causing assembly failure. Moreover, the surface of the MPO is often irregular and uneven, making it difficult to pick it up with a suction cup. Furthermore, since the MPO is directly inserted into the housing after assembly, to avoid interference, direct clamping can only insert half of it. An additional pressing mechanism is needed to fully press the MPO in. During the process of picking up the material from the box, the MPO may also slightly flip, which may lead to assembly failure. Therefore, most of the existing PCBA assembly processes with MPOs on the market are still manual assembly.

[0003] In view of the above-mentioned shortcomings, the designer actively researched and innovated to create a new type of PCBA housing handling fixture with MPO jumpers, making it more valuable for industrial use. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a PCBA housing handling fixture with MPO jumpers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A PCBA housing handling fixture with MPO jumpers includes a guide mounting plate. A first opening is provided on one side of the guide mounting plate, and a vacuum adsorption component for PCBA adsorption is slidably connected in the first opening. A second opening is provided on the other side of the guide mounting plate, and a clamping component for clamping the MPO is connected in the second opening. A clamping detection component for pressing the MPO is connected to the end of the guide mounting plate adjacent to the clamping component.

[0007] The vacuum adsorption assembly includes a suction nozzle top plate, which is connected to a guide mounting plate via a column. A second ball bushing is connected to the suction nozzle top plate, and a second guide shaft passes through the second ball bushing. A limit washer is connected to the upper end of the second guide shaft passing through the suction nozzle top plate, and a suction nozzle seat that slides in the first opening is connected to the lower end of the second guide shaft. A spring is fitted on the second guide shaft between the suction nozzle top plate and the suction nozzle seat. Vacuum suction cup A and vacuum suction cup B are connected to the suction nozzle seat.

[0008] The clamping assembly includes a cylinder mounting plate. A cylinder mounting plate is connected to the guide mounting plate located at the second opening. A gripper cylinder is connected to the cylinder mounting plate. Gripper A and gripper B, which move within the second opening, are connected to the gripper cylinder. An intermediate partition block located between gripper A and gripper B is connected to the guide mounting plate, which is opposite to the gripper cylinder and located within the second opening.

[0009] The clamping detection assembly includes an MPO pressure block and a first guide shaft. The end of the guide mounting plate has a pin hole, and a first ball bushing is connected inside the pin hole. The first guide shaft passes through the first ball bushing. The upper end of the first guide shaft, located above the guide mounting plate, is connected to a limit plate. The lower end of the first guide shaft is connected to the MPO pressure block, which is located on the side of the intermediate partition block. A detection piece that moves up and down synchronously with the MPO pressure block is connected to the MPO pressure block. A slotted photoelectric sensor that senses and cooperates with the detection piece is connected to the guide mounting plate.

[0010] Preferably, in the PCBA housing handling fixture with MPO jumper, the guide mounting plate is connected to a mounting top plate fixed on the robotic arm via a cylinder mounting plate and a connecting upright plate.

[0013] Preferably, in the aforementioned PCBA housing handling fixture with MPO jumper, the slotted optocoupler is connected to the cylinder mounting sheet metal.

[0014] By means of the above solution, this utility model has at least the following advantages:

[0015] This invention enables automatic loading and unloading of MPOs and PCBAs. It requires only two cylinders (a gripper cylinder and a pen-shaped cylinder). Through the adaptive adjustment of the flexible pressure block, the functions of MPO straightening, gripping, and pressing are integrated, simultaneously meeting the material loading and unloading needs of MPOs.

A slotted photoelectric sensor 27 that senses and cooperates with the detection piece is connected to the guide mounting plate 1.

[0029] In another embodiment, the guide mounting plate 1 is connected to a mounting top plate 26 fixed on the robotic arm via a cylinder mounting plate and a connecting vertical plate 25.

[0030] A jumper wire sheet metal 23 is connected to the guide mounting plate 1 located between the vacuum adsorption assembly 100 and the clamping assembly 200. The jumper wire sheet metal 23 has slots for securing the jumper wires, and multiple slots and the jumper wire sheet metal 23 form an M-shaped jumper wire sheet metal structure. A cylinder mounting plate metal 10 is connected to the guide mounting plate 1, and a pen-shaped cylinder 9 is connected to the cylinder mounting plate metal 10. The drive shaft of the pen-shaped cylinder 9 is located directly above the limiting plate 8 and is used to press the MPO down into the housing bottom shell 3.

[0031] The mounting plate 26 is fixed to the cylinder mounting plate 12 and the connecting plate 25 with screws. The pen-shaped cylinder 9 is fixed to the cylinder mounting sheet metal 10 with nuts.

The nozzle seat 16 can move freely within a certain range in the Z direction (i.e., the distance traveled by the spring 22).

[0034] The working principle of this utility model is as follows:

[0035] During material handling: First, the robotic arm is driven to move the guide mounting plate 1 above the material tray. Then, the robotic arm descends, and the MPO pressing block 5 first contacts the MPO. During the continuous descent, the intermediate separator block 4 is inserted between the two MPOs, and the MPO pressing block 5 is lifted and flattened. The descent stops when the detection plate 28 enters the signal point of the slotted photoelectric sensor 27. At this time, the gripper cylinder 11 closes, and the grippers A13 and B14 retract to clamp the MPO, ensuring that the MPO is aligned vertically and horizontally. At the same time, the vacuum suction cups A15 and B also contact and pick up the PCBA. The descent displacement error of the suction cups is offset by the spring 22. The M-shaped slot of the jumper sheet metal 23 is also locked between the two jumpers to prevent the jumpers from shaking during transportation, which would cause assembly failure. Then, the robotic arm is raised, lifting the MPO and PCBA 2. At this time, the positions of the MPO and PCBA are basically fixed, and the jumpers can only move slightly within the M-shaped slot without relative displacement.

[0036] During material unloading: The robotic arm drives the guide mounting plate 1 to move above the Housing bottom shell 3. Then, the robotic arm descends, and the MPO first enters the groove of the Housing bottom shell 3. It continues to descend until half of the MPO is in the groove, at which point it stops descending. At this time, the PCBA is just placed in the Housing bottom shell 3. Then, the gripper cylinder 11 is released, and the MPO pressing block 5 will descend under the action of gravity. At the same time, it can completely press the MPO into the Housing bottom shell 3. If the friction between the MPO and the Housing bottom shell 3 is too great, the MPO pressing block 5 cannot be pressed in by its own weight. At this time, the detection piece 28 is still at the signal point of the slot-shaped photoelectric sensor 27. Then, the system (PLC) will control the pen-shaped cylinder 9 to descend, and apply external force through the cylinder to completely press the MPO into the Housing bottom shell 3. Finally, the robotic arm is raised, the fixture is removed, and the assembly is completed.

[0037] At this point, the MPO & PCBA assembly work is complete.

[0038] It enables automatic picking and placing of MPO & PCBA; requiring only two cylinders (gripper cylinder and pen-shaped cylinder), the flexible pressure block adaptively adjusts to integrate the functions of MPO straightening, gripping, and pressing, while meeting the material picking and placing requirements of MPO. This not only reduces the size of the handling fixture and lowers the cost of the equipment, but also requires only one mechanism, avoiding the interaction between mechanisms, effectively improving work efficiency, and reducing the product NG rate caused by the interaction between different mechanisms.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for 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. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0042] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
