Specifically, it is located in the middle part of the door, perpendicular to the vehicle body, and plays a role in supporting the roof and the door. The B-pillar is usually a separately produced component and then welded to other parts of the vehicle body; such a design can keep the vehicle body with high strength during a collision, and at the same time, it is also convenient for adjustment and maintenance during the production process.
[0003] The traditional way of loading and unloading the B-pillar usually relies on manual operation, taking out the material from the material storage box and then placing it at the position to be welded, with low efficiency, high labor intensity and difficult to guarantee the assembly accuracy. With the development of automation technology, more and more automatic material taking and feeding devices have emerged. However, the automotive B-pillar often needs to be precisely assembled onto the vehicle in an upright state. When the material taking device automatically clamps the B-pillar, it is often difficult to ensure the upright state of the B-pillar, so it is impossible to quickly load the B-pillar and accurately position it. To solve the above problems, a new type of automatic loading and unloading fixture for an automotive B-pillar is needed. Summary of the Utility Model

[0030] As Figure 4 、 5As shown, start the moving motor 19. Driven by the sliding block 18, the material pushing plate 8 pushes the B-pillar closest to the docking frame 3 in the storage frame 2 into the docking frame 3. The controller 6 connects the circuit of the electromagnet 15 to make the electromagnet 15 adsorb and fix the B-pillar. The upper and lower ends of the B-pillar are respectively located in the upper docking groove 13 and the lower docking groove 14, which can ensure the accuracy of the B-pillar during docking and transfer; start the electric telescopic rod 20 to move the docking frame 3 away from the storage frame 2, leaving enough space for the rotation of the docking frame 3; start the rotating motor 16 to drive the support plate 4 and the docking frame 3 to rotate, so that the docking frame 3 rotates to the position where the B-pillar needs to be loaded; use the controller 6 to disconnect the adsorption of the electromagnet 15, and then start the electric telescopic rod 20 to push the B-pillar to the designated position. The whole process ensures the upright state of the B-pillar, can ensure the automatic clamping and placement of the B-pillar, and can ensure the precise positioning of the B-pillar.
