Description

Technical Field

[0001] This utility model relates to an automatic barcode scanning control mechanism with a convertible positioning fixture. Background Technology

[0002] With social development, people's lives have become more convenient, and cars have become an essential tool for most people. For safety reasons, each part needs to undergo multiple inspections before leaving the factory. To avoid omissions and ensure that a part is not missed in a certain step of the inspection, QR codes are usually marked on the parts. After each inspection, the QR code is registered to ensure that the part has completed the inspection for that item and whether the previous inspection process has been completed. Since many of the cast parts in automobiles are symmetrically distributed, the symmetrical parts on the left and right sides are also symmetrical in shape. Therefore, if the scanning and placement fixture is directly for a single part, it will require a lot of resources to prepare the fixture. Therefore, it is necessary to set up a universal fixture for symmetrical parts to reduce costs. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] like Figure 1-4 As shown, an automatic barcode scanning control mechanism with a convertible positioning fixture includes a positioning fixture 1, on which a barcode scanning mechanism 2 is mounted. The positioning fixture includes a workpiece placement plate 3, on which a fixed limiting structure 4 and a movable limiting structure 5 are provided. The workpiece placement plate slides back and forth under the barcode scanning mechanism. In use, the workpiece placement plate is first slid to the front, and then the workpiece to be scanned is placed on the workpiece placement plate. The workpiece to be scanned is limited by the fixed limiting structure and the movable limiting structure. Then the workpiece placement plate slides to the rear and under the barcode scanning mechanism. After the barcode scanning mechanism scans the code, the workpiece placement plate slides to the front again and the workpiece is removed. When it is necessary to replace symmetrical workpieces, the movable limiting structure is removed, flipped to the back, and fixed to the workpiece placement plate to achieve adaptation for symmetrical workpieces. Other barcode scanning processes are the same as described above, so they will not be elaborated further.

[0024] In this embodiment, in order to achieve the fixed limiting structure to limit the workpiece, the fixed limiting structure includes a limiting block 6, which is disposed on the rear part of the upper surface of the workpiece placement plate. The limiting block is used to limit the rear side of the workpiece to prevent the workpiece from detaching from the rear side. Furthermore, the fixed limiting structure also includes at least two limiting holes 7, which can be symmetrically distributed and correspond to the limiting posts on the back of the symmetrically arranged workpiece. The two limiting holes are respectively connected to the limiting posts on the corresponding symmetrical workpieces. The limiting holes are opened in the middle of the workpiece placement plate.

[0025] In this embodiment, in order to achieve the limiting of the front side of the workpiece by the movable limiting structure, the movable limiting structure includes a workpiece side limiting plate 8, which is inserted into the front side of the workpiece placement plate. Specifically, the workpiece side limiting plate is a right-angle plate, and the right-angle edge of the workpiece side limiting plate is in contact with one corner of the front side of the workpiece placement plate. The inclined edge of the workpiece side limiting plate is a curved edge 9 corresponding to the front side of the workpiece. At the same time, the front side of the workpiece side limiting plate is in contact with the front side of the workpiece placement plate, so that the curved edge of the inclined edge of the workpiece side limiting plate can limit the front side of the workpiece. When it is necessary to change to a symmetrical workpiece, it is only necessary to flip the workpiece side limiting plate over to achieve the limiting of the symmetrical workpiece.

[0026] In this embodiment, to specifically realize the insertion of the workpiece side limiting plate into the workpiece placement plate, the workpiece placement plate has bottom insertion holes 10 symmetrically opened on the front side of the upper surface of the workpiece placement plate. The front side of the workpiece side limiting plate has a mating insertion hole 11 corresponding to the bottom insertion hole. The bottom insertion hole and the corresponding mating insertion hole are aligned and fixed by a pin 12. In use, in order to facilitate the fixing of the workpiece side limiting plate, it is inserted by two pins. At the same time, when it is necessary to flip, it is only necessary to pull out the pins and then flip the workpiece side limiting plate. Since the bottom insertion holes are symmetrically arranged, the mating insertion holes are exchanged after flipping. After realigning, the pins are inserted to complete the fixing.

[0027] In this embodiment, to avoid missing either of the two pins, a pin end 13 is provided at the upper end of the pin, and the two pin ends are connected by a rope 14, so that the two pins are connected.

[0028] In this embodiment, in order to achieve the forward and backward sliding of the workpiece placement plate, a lead screw mechanism 15 for driving the workpiece placement plate to slide is installed under the workpiece placement plate. The lead screw mechanism includes a base 16, and lead screw mounting seats 17 are provided on the front and rear sides of the base. A lead screw 18 driven by an external motor is rotatably connected between the two lead screw mounting seats. A lead screw nut 19 is installed on the lead screw and slides back and forth with the rotation of the lead screw. The lead screw nut is fixed to the workpiece placement plate. The external motor can be fixed to one of its lead screw mounting seats. The motor drives the lead screw to rotate, thereby driving the lead screw nut to slide back and forth, thus realizing the forward and backward sliding of the workpiece placement plate.

[0029] In this embodiment, to assist the workpiece placement plate in sliding back and forth, the two lead screw mounting seats are provided with guide rods 20 parallel to the lead screws on both sides of the lead screws. A sliding joint seat 21 is provided under the workpiece placement plate corresponding to the guide rod. The sliding joint seat is slidably connected to the guide rod. The sliding joint seat is provided with guide holes 22 that cooperate with the guide rod. The sliding joint seat and the guide rod assist the workpiece placement plate in sliding back and forth.

[0030] In this embodiment, to facilitate the installation of the scanning mechanism, a scanning bracket 23 for mounting the scanning mechanism is provided above the rear side of the lead screw mechanism. A sliding groove 24 is installed under the scanning bracket, and a fixing block 25 is slidably connected to the sliding groove. The sliding groove can be an existing trapezoidal groove, and the fixing block can be a trapezoidal block. The fixing block is locked to the sliding groove by bolts. Alternatively, a vertical screw hole 26 can be provided on the bottom of the fixing block, through which a bolt 27 is screwed. The fixing block is fixed by the end of the bolt abutting against the groove surface of the sliding groove. The scanning mechanism is installed under the fixing block. Specifically, a frame 28 can be installed under the fixing block, and the existing scanning mechanism is installed through the frame 28.
