[0025] The turnover mechanism 4 is arranged outside the main conveying mechanism 2, the turnover station is arranged outside the main conveying mechanism 2, the turnover mechanism 4 comprises an operation end, the operation end extends above the main conveying mechanism 2 and can pick up the mainboard on the main conveying mechanism 2 to perform turnover in the turnover station, the pickup end of the board changing mechanism 3 can be moved to the turnover station, the pickup end of the board changing mechanism 3 can pick up the mainboard from the operation end, when the mainboard turnover action is needed, that is, when the turnover mechanism 4 is needed to cooperate, the mainboard carrier changing action is completed, the mainboard is first picked up by the turnover mechanism 4, then the turnover is performed, so that the original bottom of the mainboard faces upward, and finally the turnover mainboard is picked up by the board changing mechanism 3 and placed in another mainboard carrier.

[0026] By arranging the main conveying mechanism, the board changing mechanism and the turnover mechanism, the main conveying mechanism is used to realize the feeding and discharging of the two mainboard carriers, after the two mainboard carriers are in place, the board changing mechanism can pick up the mainboard on one of the carriers and place it on the other carrier, so as to realize the switching of the carriers, if the turnover action of the mainboard is needed, the turnover mechanism picks up the mainboard from one carrier and turns it over, so that the original bottom surface of the mainboard becomes the top surface, then the board changing mechanism picks up the mainboard and places it in another carrier, so as to complete the board changing operation. Compared with the existing board changing program, the automatic operation is more efficient, and manual operation is not needed, so that the problems of poor consistency and part wear caused by manual operation are avoided.

[0028] Correspondingly, since the side conveying mechanism 5 cannot directly deliver the carriers to the conveying assembly 21, two rail changing mechanisms 6 are also needed to be correspondingly arranged, both of which are arranged on the operation table 1 and above the two carrier loading and unloading stations respectively. The rail changing mechanism 6 comprises a grabbing end which can move between the side conveying mechanism 5 and the main conveying mechanism 2 to pick up the mainboard carrier and switch it between the side conveying mechanism 5 and the main conveying mechanism 2. During the operation, when the mainboard carrier is in place on the side conveying mechanism 5 and the mainboard carrier which has completed the board changing has left the main conveying mechanism 2, the rail changing mechanism 6 can grab the mainboard carrier on the side conveying mechanism 5 and place it on the conveying assembly 21 of the main conveying mechanism from above to realize the transfer of the mainboard carrier.

[0029] Specifically, as shown in Figure 8 The rail changing mechanism 6 comprises a moving module 61, a rotating seat 62, a grabbing frame 63, a clamping assembly 64 and a first suction head 65.

The plurality of third suction heads 46 are arranged on the claw frame 45, and are used to suck the mainboards.

[0038] The two-axis module 41 is different from the front moving module 61 and the three-axis module 31. The two-axis module 41 is composed of an X-axis module and a Y-axis module, and is arranged on the outside of the main conveying mechanism 2. Since it only needs to move towards or away from the main conveying mechanism 2 or along the length direction of the main conveying mechanism 2, it does not need to move in the Z-axis direction.

[0046] The main board carrier conversion method of the application is realized based on the main board carrier conversion device, and the main board carrier conversion method is realized as follows.

[0047] First, an SMT process carrier carrying a main board and a UF process carrier not carrying a main board need to be prepared, and after preparation, they are ready to be sent to the operation table 1, and the preparation process can be performed on the production line connected to the operation table 1.

[0048] When conversion is needed, the two main board carriers are placed on the two carrier feeding and discharging stations respectively, and one of the main board carriers has a main board placed thereon, and the carrier with the main board placed thereon can be an SMT process carrier, specifically, the SMT process carrier and the UF process carrier are placed on the two carrier feeding stations respectively, i.e., on the two side conveying mechanisms 5.

[0049] The rail changing mechanism 6 places the two carriers on the two conveying assemblies 21 through grabbing, translation, rotation and other operations.

[0050] The two conveying assemblies 21 convey the two mainboard carriers to a certain distance, which can be determined according to the distance between the two conveying assemblies 21, and the like. It should be noted that the mainboard can also be transferred on two same carriers, for example, only needs to be flipped, and the two carriers can be directly moved and discharged by the two docking conveying assemblies 21.

[0051] If the mainboard needs to be flipped, the flipping mechanism 4 picks up the mainboard from one mainboard carrier and flips it to face upward. It should be noted that after picking up, it is determined whether to directly flip according to the situation. When the identification code of the mainboard is located at the bottom, the mainboard cannot be flipped at the first time, and needs to be first photographed by the camera assembly 7. Otherwise, the mainboard is directly flipped.

[0052] After flipping, the board changing mechanism 3 moves to the flipping station and picks up the mainboard from the flipping mechanism 4. If the data of the mainboard is not entered in the previous step, the board changing mechanism 3 needs to drive the mainboard to pass through the camera assembly 7 to enter the data, and then the mainboard is placed in the UF process carrier.

[0053] After placing, the two conveying assemblies 21 convey the two mainboard carriers to the two carrier unloading stations respectively, and unload the two mainboard carriers from the operation table 1.

[0054] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, and the like within the spirit and principle of the present application should be included in the protection scope of the present application.
