[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying 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 making creative efforts shall fall within the scope of protection of the present invention.

[0056] The present invention is described in further detail below with reference to the accompanying drawings:

[0057] A cockpit assembly process, such as Figure 12 As shown, the following steps are included:

[0058] Step S1: Load the cab onto a tooling vehicle on the main line. The tooling vehicle is operated on the main line. Loading can be performed by a robotic arm. The main line can be operated continuously.

[0059] Step S2: Install accessories on the cockpit. The main line adopts a continuous operation mode.

[0060] Step S3: At the main line's unloading station, the tooling vehicle is pushed off the main line via the first unloading mechanism. The first unloading mechanism 23 comprises a push cylinder 231 and a decoupling member 232. The output end of the push cylinder 231 is provided with a one-way flap 237 that matches the tooling vehicle 4. The upper end surface of the decoupling member 232 is provided with a slide rail for the tooling vehicle 4, and the upper end surface of the slide rail gradually increases in height.

[0061] Step S4: Load the tooling vehicle onto a first circulation vehicle, wherein the first circulation vehicle has a first positioning mechanism that matches the tooling vehicle.

[0062] Step S5: The tooling vehicle is transported to the auxiliary line by the first transfer vehicle, and the tooling vehicle is mounted on the auxiliary line, and the tooling vehicle is circulated on the auxiliary line. The auxiliary line adopts an intermittent operation mode, that is, one workstation is operated at a certain interval.

[0063] Step S6: Perform quality inspection on the cockpit on the auxiliary line.

[0064] Step S7: After quality inspection, the cockpit is taken offline to obtain an empty loading vehicle.

[0065] Step S8: The empty loading vehicle is transported to the main line via a second transfer vehicle and mounted on the main line.

[0066] Execute steps S1-S8 cyclically to realize the flow of tooling vehicles and products.

[0067] The first and second transfer vehicles are used to transfer the tooling vehicle / cockpit from the main line to the auxiliary line, and then from the auxiliary line to the main line. This allows the tooling vehicle to flow between two production lines with different modes, as well as the product flow. This reduces transfer costs and eliminates the distance requirements between the main and auxiliary lines, facilitating the spatial layout of the production line. In one specific embodiment, the one-way flap is coupled to a detection switch. When the one-way flap is flipped, it triggers the operation of the push cylinder, but the arrangement of the detection switch is not limited to this.

[0068] The accessories include any one of the following components or their combination:

[0069] Crossbeam, air conditioner, steering column, skin, heater, condenser pipe, temperature and humidity sensor, PM2.5 sensor, ion generator, airbag, glove box, display, HUD wiring harness, instrument panel, light switch, air outlet duct, decorative strip, air outlet, underbody air duct, ambient light;

[0070] The quality inspection includes: power-on test and taking pictures.

[0071] Example 1

[0072] Cockpit processing includes:

[0073] The cockpit is placed on the tooling cart at workstation No. 1 by a robotic arm, and a loading cart is set up on one side of the tooling cart;

[0074] As the main line continues to operate, the accessories of the loading car are gradually installed in the cockpit of the tooling car;

[0075] The tooling vehicle passes through the first off-line mechanism and enters the fourth position;

[0076] The first transfer vehicle moves the tooling vehicle at the fourth position to the auxiliary line and mounts it at the No. 1 workstation on the auxiliary line;

[0077] As the auxiliary lines are intermittently running, the auxiliary lines in the cockpit are tested, including power-on testing, taking photos, etc.

[0078] The tested cockpit is taken off the line by a robot. At the off-line station, the product is transferred to the shipping tooling vehicle, which then becomes an empty tooling vehicle.

[0079] The empty loading vehicle enters the auxiliary line off-line station and is transferred to the first position through the second off-line mechanism and the second transfer vehicle;

[0080] The empty tool loading vehicle is pushed onto the main line through the main line's loading mechanism and enters the No. 1 workstation;

[0081] The above steps are executed cyclically to realize the flow of production line, specifically the flow of tooling vehicles and products between the main line and auxiliary line. Figure 1 The arrows show the direction of flow.

[0082] Example 2

[0083] This embodiment provides an assembly system 1 for implementing the above assembly process, 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 with a driving cabin. Figure 2 and Figure 3 Only the drive bracket 41 of the tooling vehicle 4 is shown. The tooling vehicle 4 is mounted on the main line 2. A transfer track 5 for the first circulation vehicle 6 is provided between the main line 2 and the auxiliary line 3. The main line 2 is provided with a first dismounting mechanism 23, which includes a push cylinder 231 and a decoupling member 232. The output end of the push cylinder 231 is provided with a one-way flap 237 that matches the tooling vehicle 4. The upper end surface of the decoupling member 232 is provided with a slide rail for the tooling vehicle 4, and the upper end surface of the slide rail gradually increases in height. The first circulation vehicle 6 is provided with a first positioning mechanism for the tooling vehicle 4. The auxiliary line 3 has a mounting mechanism for the tooling vehicle 4. A second dismounting mechanism is provided downstream of the auxiliary line 3, and the second circulation vehicle 7 cooperates with the second dismounting mechanism. Specifically, under the action of the first dismounting mechanism 23, the drive bracket 41 of the tooling vehicle 4 is pushed from the third position 235 to the fourth position 236.

[0084] The pushing cylinder 231 pushes the tooling vehicle 4 downstream through the one-way flap 237. The tooling vehicle 4 moves along the uncoupling 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 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.

[0085] For example, a one-way flap is coupled to a detection switch. When the one-way flap flips, it triggers the operation of a push cylinder. Specifically, the detection switch 238 installed on the main line is a proximity switch that is arranged to cooperate with the first hook member 411. When the detection switch detects a signal, the push cylinder pushes the tooling vehicle along the unhooking member. The pushing speed of the push cylinder is greater than the operating speed of the first push head of the main line. However, the arrangement of the detection switch is not limited to this.

[0086] The main line 2 is in continuous operation mode. Through the first offline mechanism 23, the tooling vehicle 4 is separated from the main line 2 and does not move continuously with the main line 2. It is in a relatively static state, which is convenient for the loading and positioning of the first transfer vehicle 6.

[0087] Figure 3 The structure of the one-way flap is shown, and the output shaft of the pushing cylinder 231 is provided with a mounting seat, and the one-way flap 237 is rotatably mounted on the mounting seat, and the right side (upstream side) of the one-way flap 237 is provided with a chamfer; the left side (downstream side) of the mounting seat is provided with a flip groove 239, and the rear end of the one-way flap 237 is 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 (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 uncoupling member 232. Among them, the tooling vehicle 4 is provided with a guide wheel 44 and a first hook part 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 part 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 part 232 to facilitate the tooling vehicle 4 to be loaded onto the first circulation vehicle 6.

[0088] Among them, such as Figure 3 and 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 portion of the L-shaped flap 413 is rotatably mounted on the downstream side of the first base via a rotating shaft 414. The upper side wall of the L-shaped flap 413 is buckled onto 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, it enters the lower side of the first base to push the L-shaped flap, causing the tooling vehicle to operate with the main line. The speed of the tooling vehicle during the process of loading or unloading may be greater than the active operating speed. The L-shaped flap can prevent the tooling vehicle from colliding with the first pusher.

[0089] Figure 4The structure of the first transfer vehicle 6 is shown: it includes a first transfer drive mechanism 65, a first base 66, a first lifting plate 63, and a turntable 61. The first transfer drive mechanism 65 is mounted on the underside of the first base 66 to drive the movement of the first transfer vehicle. The first base 66 is also equipped 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 and can be driven by a motor and a reducer. The first positioning mechanism is mounted on the turntable. The first positioning mechanism includes positioning pins 62 that match the positioning holes 46 on the underside of the tooling vehicle. In one embodiment, four positioning holes 46 and four corresponding positioning pins are provided. To reduce error accuracy, the positioning pins can be pointed pins. The first transfer vehicle 6 enters the bottom of the tooling vehicle, lifts the first lifting plate, and the tooling vehicle is separated from the main line. After rotating 180 degrees via the turntable 61, the tooling vehicle is mounted on the auxiliary line.

[0090] 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.

[0091] Figure 5 and Figure 6 The structure of a tool vehicle mounted on an 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. The driving bracket 41 of the tool vehicle 4 is provided with a second hook member 43. The lower side of the second hook member 43 is provided with a U-shaped groove 431 that matches the second pusher head 312. The second guide wheel groove 32 matches the guide wheel 44 of the driving bracket 41. The pusher head can be a bearing.

[0092] Auxiliary line 3 operates in intermittent mode. The second hook 43 securely holds the tooling cart on the second pusher 312 of auxiliary line 3. After a single rotation, the auxiliary line remains stationary, meeting the requirements for static product movement during electrical testing, quality inspection, automatic photography, and product end-of-line processing. The mounting mechanism of auxiliary line 3 may also include a proximity switch 34, compatible with the second pusher 312, to facilitate relative positioning between the second pusher and the auxiliary line, the first transfer cart, and the tooling cart.

[0093] The present invention also provides a running structure of the auxiliary line 3 to the main line 2: Figure 8, a second offline mechanism and a second circulation vehicle 7 are provided downstream of the auxiliary line 3. The second offline mechanism includes a proximity switch matching the second push head and a shortened second guide wheel groove, but is not limited to this. 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 provided on the upper side of the second lifting plate; the second positioning mechanism includes a beam groove 71 matching the lower 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, the tooling vehicle 4 is separated from the auxiliary line 3, and quickly runs 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 operation structure is adopted.

[0094] The second offline mechanism includes an adjusting cylinder 33 provided on the auxiliary line, which is used to adjust the positions of the tooling vehicle and the second transfer vehicle.

[0095] like Figure 9 and Figure 10 , the upstream of the main line 2 is provided with a line mechanism 24, which includes a line cylinder 246, a guide groove 241 and a line flap 242, and the output end of the line cylinder 246 is connected to the guide groove 241 ( Figure 9 (Only the threading cylinder is shown in the figure.) The middle portion of the threading flap 242 is hinged to the outer end of the guide slot 241. The sidewalls of the threading flap 242 extend downward and abut against the lower sidewalls of the guide slot, which limit the lower end of the threading flap 241. After the two guide wheels 44 of the tooling vehicle are inserted into the guide slot 241, the cylinder retracts, pulling the tooling vehicle into the first guide wheel slot of the main line. During operation, the first pusher 221 engages with the first hook member 411 of the tooling vehicle, allowing it to enter the main line for circulation.

[0096] The steps for bringing a tooling vehicle online include:

[0097] 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;

[0098] The guide channel 241 retracts, and the tooling cart 4 / drive bracket is pulled to the second position 26 via the upper line flap 241. The first pusher 221 of the main line 2 cooperates with the first hook 411 of the tooling cart to push the tooling cart 4 to the downstream workstation. A movable wheel 243 can be provided on the underside of the guide channel to support the guide channel 241. A second stop 247 and a cylinder can be provided downstream of the guide channel 241. The output end of the cylinder is connected to the second stop. When the tooling cart 4 is pulled to the second position, the second stop 247 extends to prevent the tooling cart from colliding with the downstream tooling cart 4 or the loading cart 8. A stop 245 can be provided at the end of the transfer track of the second transfer cart 7.

[0099] The main line 2 has a first drive mechanism and a first chain 211. A first pusher 221 is mounted on the first chain 211. The first drive mechanism drives the first chain. The main line and auxiliary line are arranged in a ring structure. The auxiliary line has a second drive mechanism 31 and a second chain 311. The second drive mechanism drives the second chain 311. A second pusher 312 is mounted on the second chain 311 via a second base 313. A stopper can be installed between the loading and unloading stations of the auxiliary line to separate the first and second transfer vehicles.

[0100] Figure 11 The main line shows the structure of the loading cart and tooling cart. The loading cart 8 is mounted on the first pusher 221 of the main line. The loading cart 8 and the tooling cart 4 are spaced apart. The loading cart 8 is used to place accessories such as beams, air conditioners, steering columns, skins, heaters, condenser pipes, temperature and humidity sensors, PM2.5 sensors, ion generators, airbags, glove boxes, displays, HUD wiring harnesses, instrument panels, light switches, air ducts, decorative strips, air outlets, underbody air ducts, ambient lighting, etc. While the main line is running continuously, assemblers remove accessories from the loading cart and assemble them accordingly. The auxiliary line is used for quality inspection and cockpit assembly. It adopts an intermittent operation mode, rotating once / at a workstation according to the beat and at regular intervals. The tooling cart is equipped with product positioning holes 42 that match the cockpit.

[0101] The present invention enables tooling vehicles / products to flow through production lines with two different operating modes.

[0102] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
