DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

It is to be understood that the figures and descriptions of embodiments of a Universal Box Build (UBB) have been simplified to illustrate elements that are relevant for a clear understanding, while eliminating, for the purpose of clarity, many other elements found in typical vehicle systems. Those of ordinary skill in the art may recognize that other elements and/or steps are desirable and/or required in implementing the present invention. However, because such elements and steps are well known in the art, and because they do not facilitate a better understanding of the present invention, a discussion of such elements and steps is not provided herein.
The non-limiting embodiments described herein are with respect to system and method of activating or triggering predetermined functions for vehicle electromechanical systems based on image recognition and radio frequency systems. Other electronic devices, modules and applications may also be used in view of these teachings without deviating from the spirit or scope as described herein. The UBB may be modified for a variety of applications and uses while remaining within the spirit and scope of the claims. The embodiments and variations described herein, and/or shown in the drawings, are presented by way of example only and are not limiting as to the scope and spirit. The descriptions herein may be applicable to all embodiments of the UBB although it may be described with respect to a particular embodiment.
A Universal Box Build (UBB) may be used to create consumer electronic devices for multiple brands including tools to program positions, datum, and fiducials and assemble the devices with low changeover time specifications. The UBB may have full traceability and data recording using various sensors, (for example, torque on screws, force applied when placing the components, deflection on a printed circuit board (PCB) main board, force when a memory module is inserted, a parts presence indicator, and a machine vision to record the incoming components state) while also using the their characteristics for handling to address the variability of off the shelve parts. Recorded data and images for quality validation and traceability may be transmitted to a Manufacturing Execution System (MES) making the cell Internet of Things (IoT) ready.
The end effectors and work flow of the cell may be designed to accommodate several standards of components with the universal function train of thought from the group up. Adaptability to several standard components has been accomplished with adjustable gripping tools. Precise positioning is done with respect to fixed fiducials from the manufacturing of the components and characteristics. For traceability, all of the measurements and quality assurance data may be connected to the MES system, making the cell IOT ready.
FIG. 1 is an example of a Universal Box Build (UBB). The UBB 100 includes a box 101, a rolling cart 102, a kitting tray 103, a robot 104, a tool changer 105, a robotized screw tool 106, a gate 107, an end of arm tool box 108, and a human interface module 109. The tool box 108 may include a heatsink gripper, an inertia resistant screw bit, a memory modules gripper, an ODM MB gripper, a CPU gripper, a MB gripper, a CPU cover gripper, and a CPU socket latch. Each one of these tools may attach to the tool changer to add a specific piece, for example a heatsink, a CPU, a memory module, and the like, to the PCB. This interchangeability may allow the UBB to perform the necessary functions of assembling to the PCB after a user input of the required specifications.
The user may input the specifications of the PCB into the human module interface. The computer may then respond by bringing in the product chassis from the rolling cart 102 into the UBB 101. The UBB may then assemble onto the PCB based on the specifications inputted by the user the quantities of components from the kitting tray. The robot 104 is a robotic arm that engages the tool changer 105 to pick up the necessary tool from the tool box 108. Once the robot 104 has the necessary tool, it moves to the kitting tray 103 to obtain the PCB that will be assembled to the chassis. The robot 104 picks up the necessary piece and places it on the PCB. The screw tool 106 then attaches the necessary piece(s) to the PCB. Once all of the pieces are attached to the PCB based on the inputted specifications, the rolling cart 102 slides out from the UBB to allow the user to obtain the finished product.
