[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. 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.

[0052] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0053] The present invention provides a cockpit production line 1, such as Figure 1-3 As shown, it includes a main line 2, an auxiliary line 3, a first circulation vehicle 6 and a tooling vehicle 4 of a driving cabin. Figure 2 and Figure 3 Only the driving bracket 41 of the tooling vehicle 4 is shown, the tooling vehicle 4 is mounted on the main line 2, and the transfer track 5 of the first circulation vehicle 6 is arranged between the main line 2 and the auxiliary line 3; the main line 2 is provided with a first offline mechanism 23, the first offline mechanism 23 includes a pushing cylinder 231 and a decoupling member 232, the output end of the pushing cylinder 231 is provided with a one-way flap 237 matching the tooling vehicle 4, the upper end surface of the decoupling member 232 is provided with a slide rail of the tooling vehicle 4, and the height of the upper end surface of the slide rail gradually increases; the first circulation vehicle 6 is provided with a first positioning mechanism of the tooling vehicle 4. Specifically, under the action of the first offline mechanism 23, the driving bracket 41 of the tooling vehicle 4 is pushed from the third position 235 to the fourth position 236.

[0054] The pushing cylinder 231 pushes the tooling vehicle 4 downstream through the one-way flap 237, and the tooling vehicle 4 moves along the unhooking piece 232 and gradually increases its position, so that the tooling vehicle 4 is separated from the main line. The first circulation vehicle 6 loads the tooling vehicle through the first positioning mechanism and then transfers it to the auxiliary line 3, and mounts the tooling vehicle 4 on the mounting mechanism, thereby realizing the transfer of the tooling vehicle / cockpit from the main line to the auxiliary line, reducing the cost of transfer, and having no requirement for the distance between the main line and the auxiliary line, which is beneficial to the spatial layout of the production line.

[0055] For example, the one-way flap is coupled with the detection switch, and after the one-way flap is turned over, the operation of the push cylinder is triggered; specifically, the detection switch 238 installed on the main line is a proximity switch that cooperates with the first hook member 411. When the detection switch detects a signal, the tooling vehicle is pushed along the unhooking member by the push cylinder, wherein the pushing speed of the push cylinder is greater than the running speed of the first push head of the main line. However, the arrangement of the detection switch is not limited to this.

[0056] The main line 2 is in continuous operation mode. The first offline mechanism 23 is used to separate the tooling vehicle 4 from the main line 2 and stop moving with the main line 2 . The tooling vehicle 4 is in a relatively static state, which is convenient for loading and positioning of the first circulation vehicle 6 .

[0057] Figure 3The structure of the one-way flap is shown, and a mounting seat is provided on the output shaft of the push cylinder 231, and the one-way flap 237 is rotatably mounted on the mounting seat, and a chamfer is provided on the right side (upstream side) of the one-way flap 237; a flip groove 239 is provided on the left side (downstream side) of the mounting seat, and the rear end of the one-way flap 237 abuts against the side wall where the flip groove 239 is located, forming a limiting structure. Under the push of the tooling vehicle, the one-way flap 237 flips to the left side (downstream), and under the push of the main line, the tooling vehicle moves downstream; under the action of the limiting structure, after the one-way flap is reset, it pushes the tooling vehicle 4 to the left (downstream), so that the tooling vehicle moves along the upper surface of the unhooking member 232. Among them, the tooling vehicle 4 is provided with a guide wheel 44 and a first hook member 411, the main line 2 is provided with a first guide wheel groove 27 for accommodating the guide wheel 44, and a first push head 221 matching the first hook member 411, and a notch is provided on the front side wall of the first guide wheel groove 27 on the lower side of the unhooking member 232, so as to facilitate the tooling vehicle 4 to be loaded onto the first circulation vehicle 6.

[0058] Among them, Figure 3 and Figure 7 The first hook member 411 includes a first base and a flap mechanism 412. The flap mechanism 412 includes an L-shaped flap 413. The middle part of the L-shaped flap 413 is rotatably mounted on the downstream side of the first base through a rotating shaft 414. The upper side wall of the L-shaped flap 413 is buckled on the upper side of the first base, and the other side wall extends downward to cooperate with the first pusher. The first base has an upper side wall, and its front end may also be provided with a side wall. During the operation of the first pusher of the main line, the lower side of the first base is entered to push the L-shaped flap, so that the tooling vehicle can run with the main line; the speed of the tooling vehicle in the process of going online or offline may be greater than the active operation speed, and the L-shaped flap can avoid the collision between the tooling vehicle and the first pusher.

[0059] Figure 4 The structure of the first circulation vehicle 6 is shown: it includes a first circulation drive mechanism 65, a first base 66, a first lifting plate 63 and a turntable 61. The first circulation drive mechanism 65 is installed on the lower side of the first base 66 to drive the movement of the first circulation vehicle. The first base 66 is also provided with a first cylinder and a guide column 67. The output end of the first cylinder is connected to the first lifting plate 63. The turntable 61 is rotatably mounted on the first lifting plate 63. The turntable 61 can be driven by a motor and a reducer. The first positioning mechanism is installed on the turntable. The first positioning mechanism includes a positioning pin 62 that matches the positioning hole 46 on the lower side of the tooling vehicle. In a specific embodiment, four positioning holes 46 and four corresponding positioning pins are provided. In order to reduce the error accuracy, the positioning pin can be in the form of a pointed pin. The first circulation vehicle 6 enters the bottom of the tooling vehicle, lifts the first lifting plate, and makes the tooling vehicle separate from the main line. After rotating 180 degrees through the turntable 61, the tooling vehicle is mounted on the auxiliary line.

[0060] Among them, the first circulation driving mechanism 65 adopts a gear driven by a servo motor, and a rack matching the gear is arranged on the transfer track to ensure the precise positioning of the circulation vehicle when it stops running.

[0061] Figure 5 and Figure 6 The structure of the tool vehicle mounted on the auxiliary line is shown. The mounting mechanism of the auxiliary line 3 includes a second guide wheel groove 32 and a second pusher head 312 mounted on a second chain 311. A second hook member 43 is provided on the driving bracket 41 of the tool vehicle 4. A U-shaped groove 431 matching the second pusher head 312 is provided on the lower side of the second hook member 43.

[0062] The auxiliary line 3 adopts intermittent operation mode, and the second hook member 43 can firmly hold the tooling vehicle on the second pusher 312 of the auxiliary line 3. After the auxiliary line rotates once, it is in a static state to meet the requirements of electrical detection station, quality inspection, automatic photography and offline product static. The mounting mechanism of the auxiliary line 3 can also include a proximity switch 34 that matches the second pusher 312. It is used for relative positioning between the second pusher and the auxiliary line, the first circulation vehicle and the tooling vehicle.

[0063] The present invention also provides a running structure from the auxiliary line 3 to the main line 2: Figure 8 , the second offline mechanism and the second circulation vehicle 7 are arranged downstream of the auxiliary line 3. The second offline mechanism includes a proximity switch matching the second pusher head and a shortened second guide wheel groove, but is not limited thereto. The front side wall of the second guide wheel groove can also be removed in the second offline mechanism. The second circulation vehicle 7 is provided with a second circulation drive mechanism 75, a second base 76, a second lifting plate 72 and a second positioning mechanism. The second circulation drive mechanism 75 is installed on the lower side of the second base 76. The second base 76 is provided with a second cylinder and a second guide column 73. The output end of the second cylinder is connected to the second lifting plate 72. The second positioning mechanism is arranged on the upper side of the second lifting plate; the second positioning mechanism includes a beam groove 71 matching the lower side cross beam 45 of the tooling vehicle 4, which is used for positioning the tooling vehicle and the second circulation vehicle. After alignment, the second lifting plate 72 is lifted to separate the tooling vehicle 4 from the auxiliary line 3 and quickly run to the main line 2. After the tooling vehicle is on the main line, it returns to the auxiliary line to wait. In order to ensure the accurate positioning of the second circulation vehicle, a gear and rack operating structure is adopted.

[0064] The second offline mechanism includes an adjusting cylinder 33 arranged on the auxiliary line, which is used to adjust the positions of the tooling vehicle and the second circulation vehicle.

The middle part of the upper line flap 242 is hinged at the outer end of the guide groove 241. The side wall of the upper line flap 242 extends downward and abuts against the lower side wall of the guide groove. The lower side wall of the guide groove limits the lower end of the upper line flap 241. After the two guide wheels 44 of the tooling vehicle are inserted into the guide groove 241, the cylinder retracts and pulls the tooling vehicle into the first guide wheel groove of the main line. During the operation of the first push head 221, it cooperates with the first hook member 411 of the tooling vehicle and enters the main line for circulation.

[0066] The steps to put the tooling vehicle online include:

[0067] The second transfer vehicle 7 transports the tooling vehicle 4 to the first position 25 via the transfer track 5; the guide groove 241 extends, and the guide wheel 44 of the tooling vehicle at the first position is nested into the guide groove 241 via the upper line flap 242;

[0068] The guide groove 241 retracts, and the tooling vehicle 4 / driving bracket is pulled to the second position 26 through the upper line flap 241; the first push head 221 of the main line 2 cooperates with the first hook member 411 of the tooling vehicle to push the tooling vehicle 4 to the downstream station. Among them, a moving wheel 243 can be provided on the lower side of the guide groove to support the guide groove 241, and a second stopper 247 and a cylinder can be provided downstream of the guide groove 241. The output end of the cylinder is connected to the second stopper.
