Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0027] See also Figure 1-2 This embodiment provides a flexible online double engraving mechanism, including two left and right engraving mechanisms, namely, a shell engraving mechanism A and an engraving mechanism B. The engraving mechanism includes a positioning frame 1, a column 2 and an engraving machine 7. The slide rail 4 is installed on the upper end of the positioning frame 1. The bottom of the positioning frame 1 is fixedly installed with a supporting foot, and the supporting foot is installed on the ground through anchor bolts.
[0028] An electric-controlled cylinder 3 is installed on the positioning frame 1. The outer cylinder end of the electric-controlled cylinder 3 is fixedly connected to the upper edge of the slide rail 4. A slide plate is fixedly installed on the output end of the electric-controlled cylinder 3. When the electric-controlled cylinder 3 is extended or retracted, it can move the slide plate in the horizontal direction, that is, in the X direction.
[0029] The column 2 is mounted on the slide plate by bolts, and when the slide plate slides, it can slide with the column 2.
[0030] A slide groove is provided on the slide rail 4, and a slider matching the slide groove is fixedly installed at the bottom of the slide plate, so that the slide plate slides along the telescopic direction of the electric control cylinder 3. The structure of the slide groove is not limited, and it can be a rectangular structure, a T-shaped structure or an isosceles trapezoidal structure.
[0031] A first cylinder 6 is fixedly installed on the upper end of the column 2. The first cylinder 6 is placed vertically, and the engraving machine 7 is fixedly installed together with the telescopic end of the first cylinder 6; when the first cylinder 6 is telescoped, it can move the engraving machine 7 in the vertical direction, that is, in the Z direction.
[0032] A sensor 10 is fixedly installed at the bottom of the engraving machine 7 on the engraving mechanism A and at the bottom edge of the side away from the column 2. A positioning pin 9 is also fixedly installed at the bottom of the engraving machine 7.
[0033] On the ground, a support frame 20 is also installed through anchor bolts. When the support frame 20 is installed on the ground, it forms a floor. A clamp 18 is fixedly installed at the upper end of the support frame 20. The clamp 18 is preferably a pneumatic cylinder. A positioning hole is also provided in the upper part of the support frame 20. When the positioning pin 9 moves downward with the engraving machine 7, it can be inserted into the positioning hole, thereby achieving positioning.
[0034] The support frame 20 is in the shape of a "mu" character frame structure. A plurality of square tubes 21 are fixedly installed above the "mu" character frame. The plurality of square tubes 21 are connected together by steel plates. A placement portion with an open upper end is formed between the plurality of square tubes 21 and the steel plates. The positioning hole is opened on the steel plate, as Figure 5 shown.
[0035] The engraving mechanism A and the engraving mechanism B are located on both sides of the support frame 20. Along the direction of the vehicle body's advancement, the engraving mechanism A is located on the right side of the support frame, and the engraving mechanism B is located on the left side of the support frame 20, as Figure 1-2 shown.
[0036] The engraving mechanism B is composed of a positioning frame 1, a column 2, an engraving machine 7, an electric control cylinder 3, a positioning pin 9, a sensor 10, and a first cylinder 6, as Figure 4 shown. There is one sensor 10 on the engraving mechanism B, and it is installed at the bottom edge on the side of the engraving machine 7 away from the column 2. There are 2 positioning pins 9. One is on the engraving machine housing below the maintenance sensor 10, and the other is at the bottom edge on the side of the engraving machine 7 close to the column 2. The connections between the other respective structures are the same as those described above and will not be elaborated here.
[0037] The engraving mechanism is installed inside the production line body, and the support frame 20 is installed together with the production line. After the lower body assembly is automatically transported to this station and lowered after being welded in the previous process, the engraving machines on the left and right sides receive the vehicle arrival signal through PLC vehicle type information transmission.
[0038] Engraving mechanism A: The column 2 on the engraving mechanism A slides along the slide rail 4 to the engraving preparation position respectively through the bottom electric control cylinder 3. The support mechanism 5 on the engraving mechanism A is pushed by the second cylinder 8 (as shown in the figure, the cylinder body of the second cylinder 8 is fixed on the slide plate) to contact and fit with the vehicle body. Refer to Figure 3 shown. The support mechanism 5 has two vertical direction limits. A second support mechanism 52 is provided at the bottom position of the engraving machine. The second support mechanism 52 is driven by a single cylinder body 81 alone. The two support mechanisms are actually rotatably connected to the slide plate. The cylinder drives the two to make a rotational movement, and then presses and fits with the vehicle body. Referring to the figure, the slide plate and the surrounding structures reserve a space for rotation. The support mechanism rotates in a way to reserve an adjustment space for the placement of the vehicle body.
[0039] The engraving machine 7 is lowered downward along the Z direction by the first cylinder 6, and the positioning pin 9 located thereon enters the floor positioning hole on the vehicle body for positioning. After the sensor 10 located on the engraving machine 7 senses the plate, the engraving machine 7 starts to engrave the VIN code;
[0040] Engraving mechanism B: At the same time, the upright column 2 on the engraving mechanism B slides along the slide rail 4 to the engraving preparation position through the bottom electric control cylinder 3, and the engraving machine 7 on the engraving mechanism B is lowered along Z by the first cylinder 6 to the positioning pin 9 located thereon and enter the positioning hole of the seat beam for positioning. After the sensor 10 on the engraving machine 7 senses the plate, the engraving machine 7 starts to engrave the VIN code;
[0041] After the engraving mechanisms on both sides have finished printing, they automatically retreat to the engraving preparation position under the action of the electric control cylinder 3;
[0042] At this time, the clamps 18 located in the line body are all opened after receiving the engraving completion signal, and the lower body assembly is raised to the conveying preparation position through the slide. The slide is a component used in the existing body production line and will not be described here.
[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
