[0002] The refrigerator door body includes an outer door panel and a rectangular frame structure for fixing the outer door panel. The rectangular frame structure is composed of two vertically arranged columns and two horizontally arranged end covers. Since electronic components and magnets are designed inside the columns, the refrigerator columns adopt a split design, including an upper cover plate and a lower cover plate, which are injection molded separately. The electronic components and magnets are installed in the cavity between the upper cover plate and the lower cover plate, and then the upper cover plate and the lower cover plate are locked and fixed with screws, and the refrigerator column assembly is completed.

[0003] In order to ensure the quality of the product, multiple tests are required before it leaves the factory. After all tests are passed, the product will be marked to facilitate product traceability. The tests include insulation, withstand voltage, resistance continuity, magnet polarity and visual inspection of screws.

[0004] The existing technology combines insulation, withstand voltage and resistance continuity tests, and uses electronic component detection equipment to detect the electronic components in the refrigerator column, followed by electronic component detection, magnet polarity detection and screw visual detection, and finally laser marking. The refrigerator column needs to be transferred between various devices throughout the process, which is inefficient and needs to be improved. Utility Model Content

[0005] In order to improve the efficiency of refrigerator door post detection and marking, the present application provides an all-in-one refrigerator post marking and detection machine.

[0008] By adopting the above technical solution, the operator places the refrigerator column in the positioning assembly and connects the refrigerator column to the electronic component detection component. The positioning assembly fixes the refrigerator column, and the electronic component detection component, magnetic pole detection component and camera are started for detection. After the detection is completed, the laser marking machine prints a barcode in the marking area of ​​the refrigerator column. Automated electronic component detection, magnet polarity detection and screw visual detection are realized, and marking can be performed at the same time, improving the efficiency of detection and marking.

[0009] Optionally, the positioning component includes a first fixture, a second fixture, and an electric sliding table. The electric sliding table is horizontally installed on the workbench. The first fixture is installed on the electric sliding table, and the second fixture is installed on the workbench. The electric sliding table drives the first fixture to approach or move away from the second fixture.

[0010] By adopting the above technical solution, the electric sliding table drives the first fixture to press the refrigerator column tightly against the second fixture. The first fixture and the second fixture clamp the refrigerator column from the length direction thereof, realizing the positioning of the refrigerator column. In addition, the slidably arranged first fixture can be adapted to refrigerator columns of various sizes.

[0011] Optionally, a first pressing cylinder is installed on the electric sliding table. A first pressing block is installed on the cylinder shaft of the first pressing cylinder. The first pressing cylinder drives the first pressing block to approach or move away from the first fixture in the horizontal direction. The driving direction of the first pressing cylinder is set perpendicular to the driving direction of the electric sliding table. A second pressing cylinder parallel to the first pressing cylinder is installed on the workbench. A second pressing block is installed on the cylinder shaft of the second pressing cylinder. The second pressing cylinder drives the second pressing block to approach or move away from the second fixture in the horizontal direction.

[0012] By adopting the above technical solution, the operator places the refrigerator column against the first fixture. The first pressing cylinder drives the first pressing block to fix the refrigerator column on the first fixture from the side. The electric sliding table drives the first fixture and the first pressing cylinder to move, and drives the refrigerator column to move while maintaining the clamping state. When the end wall in the length direction of the refrigerator column abuts against the second fixture, the second pressing cylinder drives the second pressing block to fix the refrigerator column on the second fixture from the side. The refrigerator column is fixed in both the length direction and the width direction, realizing the precise positioning of the refrigerator column.

[0013] Optionally, a travel switch is embedded in the second fixture. An operation console is installed beside the workbench.

[0014] By adopting the above technical solution, when no refrigerator column is placed on the first fixture and the second fixture, the electric sliding table controls the distance between the first fixture and the second fixture to be greater than the length of the refrigerator column to be detected. The operator places the refrigerator column flat on the electric sliding table, starts the marking and detection integrated machine, and the PLC controller controls the first pressing cylinder to start. The first pressing block presses the refrigerator column against the first fixture. At the same time, the electric sliding table drives the first fixture and the first pressing cylinder to approach the second fixture, driving the refrigerator column to approach the second fixture. During the approaching process, the end wall of the refrigerator column away from the first fixture contacts the contact point of the travel switch and pushes the contact point into the second fixture. Until the end wall of the refrigerator column abuts against the second fixture, the contact point completely retracts into the second fixture and the travel switch is triggered. The PLC controller controls the electric sliding table to stop moving and the second pressing cylinder to start. The second pressing block presses the refrigerator column against the second fixture to realize the positioning of the refrigerator column, and it is difficult for the refrigerator column to move by itself. At this time, the magnetic pole detection component and the camera start to detect and feedback the detection results to the PLC controller. After receiving the feedback result, the PLC controller controls the laser marking machine to start and print barcodes on the refrigerator column. It realizes automatic detection and marking and improves efficiency.

[0016] By adopting the above technical solution, the operator places the refrigerator column flat on the first fixture and the second fixture. At this time, one end of the refrigerator column away from the first fixture is located on the extension plate. When the first fixture presses the refrigerator column against the second fixture, the magnet installation position of the refrigerator column is directly above the extension plate and also directly above the magnetic pole detection component. The magnetic pole detection component detects the magnetic pole of the magnet through the rectangular groove, improving the accuracy.

[0017] Optionally, roller slides are installed on the bottom wall of the gantry. There are two roller slides, and the two roller slides are arranged oppositely. A slider is arranged between the two roller slides, and the slider is slidably matched with the two roller slides.

The lower driving block is connected to the electric slide table, and the upper driving block is connected to the tooling plate.

[0020] By adopting the above technical solution, the movement of the electric slide table drives the lower driving block to move. The lower driving block drives the upper driving block to move synchronously through the belt, realizing the synchronous movement of the laser marking machine and the refrigerator column placed on the electric slide table. The laser marking machine is always located directly above the marking area and can be automatically adapted to refrigerator columns of various lengths.

[0021] Optionally, the adjusting member includes a horizontal shaft rod, a vertical shaft rod, a transverse bevel gear, a longitudinal bevel gear, and an adjusting block. A vertical plate is installed on the tooling plate. The horizontal shaft rod is rotatably connected to the vertical plate through a rotating seat. The transverse bevel gear is fixedly arranged on the horizontal shaft rod. A knob is installed at one end of the horizontal shaft rod away from the transverse bevel gear; a horizontal plate is installed on the tooling plate.

The vertical bevel gear drives the vertical shaft rod to rotate in the screw hole of the adjusting block, forcing the adjusting block to rise or fall along the track, thereby driving the laser marking machine to rise or fall. The height adjustment of the laser marking machine is realized, which can be adapted to the refrigerator columns of various thicknesses. During the adjustment process, the fixing bolt slides in the chute following the adjusting block. After adjusting to the appropriate height, the operator tightens the fixing bolt to reinforce the adjusting block and fix the height of the adjusting block.
