[0039] The present invention will be further explained below in conjunction with the accompanying drawings and embodiments:

[0040] Example

[0041] like Figure 1 As shown, the present embodiment provides a transmission test line roller conveyor system, in which a transmission transfer roller line 8 to be tested (the main test roller line in the present system), an empty pallet return roller line 12 (the empty pallet roller line in the present system), a transmission transfer roller line 13 after testing (the roller line after testing in the present system) and a transmission transfer roller line 14 to be tested (the auxiliary test roller line in the present system) are arranged in sequence longitudinally, and 8 AMT test benches and 4 MT test benches are symmetrically arranged on the west side of the transmission transfer roller line 8 to be tested and on the east side of the transmission transfer roller line 14 to be tested; the test benches symmetrical in east-west direction are connected by 3 groups of transverse roller groups consisting of 2 transverse roller lines, and the transverse roller lines form several connection points with the above 4 longitudinally arranged roller lines, and a turntable is arranged on each connection point, which has the function of identifying pallet information and adjusting the posture of the transmission, and converting the corresponding posture according to the transmission pallet label information to ensure that the pallet is transferred to the destination set by the PLC;

[0042] Among them, 4 AMT test benches constitute the AMT test area 2 of the north assembly line, which is located on the north side of the test line; 2 MT test benches constitute the MT test area of ​​the assembly workshop, which is located on the west side of the test line; 2 AMT test benches constitute the AMT test area of ​​the south assembly line, which is located on the east side of the test line. The above test benches can be replaced at will according to actual conditions to meet the needs of the actual production line.

[0043] The north assembly line interface 1 is the north assembly area, and correspondingly, the south assembly line interface 4 is the south assembly area; the north assembly line interface 1 is provided with two roller line channels, namely the north return channel and the north conveying channel, the north return channel is connected to the north end of the empty pallet roller line 12, and the north conveying channel is connected to the transmission transfer roller line 8 to be tested; the south assembly line interface 4 is also provided with two roller line channels, namely the south return channel and the south conveying channel; among them, the south return channel is connected to the south end of the empty pallet roller line 12, and the south conveying channel is connected to the transmission transfer roller line 14 to be tested.

[0044] After the test, one branch at the output end of the transmission transfer roller line 13 flows through the test line offline point 7, which is used for the transmission test offline and moved to the paint line for painting. After the test, another branch at the output end of the transmission transfer roller line 13 flows through the rework area 6, which is used to repair the faulty transmission.

[0045] The specific working principle is as follows:

[0046] The pallets of the two assembly lines and the transmissions connected together enter the test lines from the north and south sides of the test lines respectively, so the two assembly lines are also arranged on the north and south sides of the factory respectively. During the production process, an industrial computer can also be used to configure a test bench for the transmission of each assembly line. The transmission transfer roller line 8 to be tested and the transmission transfer roller line 14 to be tested can transport the transmission to the test bench corresponding to the corresponding test area according to the pre-configured plan; the AMT and MT box types of the transmission are distinguished by the pallet RFID tag information, and whether the transmission comes from the south assembly line or the north assembly line. The transmission transfer roller line 8 to be tested or the transmission transfer roller line 14 to be tested transfers the transmission to the corresponding test bench, and after the transmission test is offline, the empty pallet is transported back to their respective assembly areas (the south assembly area and the north assembly area) according to the pallet information.

[0047] like Figure 2 As shown, the transmission connected to the pallet enters from the conveying channel of the north assembly line interface 1, and is transported to the first turntable 9 after the RFID reader / writer head of the transmission transfer roller line 8 to be tested recognizes the pallet information. The first turntable 9 recognizes the direction of the transmission according to the pallet information and rotates the posture of the transmission into place in advance, that is, adjusts the input shaft end of the transmission to face the direction of docking with the test bench to be tested (here, the offline test bench 10). After the test on the offline test bench 10, the transmission is adjusted to its original posture through the second turntable 11, and then passed through the third turntable 15, the fifth turntable 17, and the eighth turntable 18. The transmission is transported to the transmission transfer roller line 13 on the platform 20 after testing. The transmission transfer roller line 13 transports the transmission to the test line offline point 7, where the operator lifts the transmission and transports it to the paint line for painting. After the transmission is offline, the empty pallet passes through the empty pallet return roller line 12 to identify the information and then transports it back to the return channel of the north assembly line interface 1 and back to the north assembly point. Of course, if the transmission comes from the south assembly line interface 4, it can also be transported back to the south assembly line interface 4 through the empty pallet return roller line 12 through several turntables, and then transported back to the south assembly point.

[0048] According to Figure 2As shown, if both test benches on the west side are occupied, the transmission to be tested located on the transmission transfer roller line 8 will be transported to the test bench corresponding to the test area on the east side through the first turntable 9, the second turntable 11, the third turntable 15, the fifth turntable 17 and the sixth turntable 18, as well as the transmission transfer roller line 14. Similarly, if a test bench on the east side is occupied, it can be transported to another test bench on the opposite side through the seventh turntable 19 for testing. During the transportation process, any turntable can adjust the desired posture of the transmission and restore the posture. The above operations can realize balanced testing of the system, thereby achieving the purpose of balanced production.

[0049] When a transmission has not been flashed and calibrated before testing, but is determined to be a faulty transmission after testing, the transmission will be transported to the rework area 6 via the post-test transmission transfer roller line 13 for rework.

[0050] The above embodiment is only one of the implementation methods that can realize the technical solution of the present invention. The scope of protection claimed by the present invention is not limited only to this embodiment, but also includes changes, replacements and other implementation methods that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention.
