[0002] The assembly of a bearing seat is a process of assembling multiple parts used by the bearing seat. In the existing automatic assembly line of various industrial products, a rotary table type automatic assembly line is a relatively common choice. Such a rotary table type automatic assembly line is not only small in structure, but also fast in assembly speed and high in overall work efficiency for products with a small number of parts. The specific working process is to set multiple carriers on the rotary table in the circumferential direction, and sequentially set multiple assembly devices around the rotary table, so that the products on the carriers rotate with the rotary table and sequentially pass through feeding, assembly and discharging, and finally the empty carriers return to the feeding position.

[0003] However, in the actual production process, one or several carriers on the rotary table may occasionally malfunction, resulting in the carrier being unable to be normally used. For example, the product is stuck on the carrier and cannot be discharged, or the carrier position is offset due to loosening after long-term use, etc. At this time, the entire assembly line needs to be stopped for maintenance, and after the technical personnel replace the faulty carrier, the assembly line can be restarted. This not only affects the assembly efficiency of the product, but also requires a high response time for the technical personnel to respond to the fault.

Each work station corresponds to a work area on the rotary table, in the embodiment, the displacement mechanism 7 drives the carriers 6 in the bearing unit to move, so that one of the carriers 6 is located in the corresponding work area as the current working carrier 6, and the remaining carriers 6 are used as standby carriers, when the current working carrier 6 in the work area fails to work, the displacement mechanism 7 can drive the failed working carrier 6 out of the work area, and replace the standby carrier 6 into the work area, so that the failure of the single carrier does not affect the assembly work of the whole assembly line.

[0028] It should be understood that the detection of the failure of the carrier 6 can be realized by means of various existing sensors, and the control host of the assembly line controls the corresponding displacement mechanism after receiving the failure detection information. In this process, according to the type of the carrier and the product, any commercially available sensor is selected to realize the failure detection, which is a conventional technical means in the field of sensors, and therefore it is not described in detail in this embodiment.

[0029] Based on the preferred example of the displacement mechanism 7 in the above embodiment, the displacement mechanism 7 comprises a rotating base 7.1 which rotates with the rotary table 3 around its own axis, all the carriers 6 in the same bearing unit are fixed on the rotating base 7.1, and a driver is arranged between the rotating base 7.1 and the rotary table 3 for driving the rotating base 7.1 to rotate.

[0030] Preferably, as shown in Figure 6 The two carriers 6 are symmetrically arranged along the longitudinal plane where the center line of the rotating base 7.1 is located. The rotating base 7.1 is driven to rotate by the driver, so that the two carriers 6 can be alternately moved into the corresponding working area.

[0031] Based on the above preferred embodiment, the rotating disc 3 has a circular mounting groove 8 at the position corresponding to the rotating base 7.1, the mounting groove 8 penetrates the upper end surface and the lower end surface of the rotating disc 3 in the thickness direction, the rotating base 7.1 is embedded in the mounting groove 8, and the outer side wall of the rotating base 7.1 is provided with a sliding block (not shown in the figure), and the inner wall of the mounting groove 8 is provided with a sliding groove 3.1 matched with the sliding block, and the sliding block is slidingly matched in the sliding groove 3.1. Specifically, as shown in Figure 5 The cross section of the sliding groove 3.1 is a trapezoidal structure with large outer side and small inner side, and the sliding block is matched with the sliding groove 3.1, so that the rotating base 7.1 is rotated around its axis by the matching relationship between the sliding block and the sliding groove 3.1.

[0032] Further, the driver is a driving motor 7.2 fixed below the rotating base 7.1, and the lower end surface of the rotating disc 3 is fixed with an arc-shaped rack 7.3 arranged around the mounting groove 8, and the output shaft of the driving motor 7.2 is connected with the arc-shaped rack 7.3 through a gear set.

[0033] As shown in Figure 4 The part of the mounting groove 8 intersects with the outer contour of the rotating disc to form a notch, and the rotating base 7.1 includes a base block 7.1.1 in the shape of an I-beam, the two ends of the base block 7.1.1 along its length direction form arc surfaces 7.1.2 matched with the mounting groove 8, the sliding block is arranged on the arc surface 7.1.2, the two sides of the base block 7.1.1 along its width direction have assembly grooves 7.1.3, the carrier 6 is embedded in the assembly groove 7.1.3, and the outer side surface of the base block 7.1.1 along the width direction has a passage 8.1 left between the inner wall of the mounting groove 8, and the width of the passage 8.1 is designed to allow the product 14 to pass through.

[0034] Specifically, the rotating disc 3 is provided with a mechanical arm 9 for grabbing the product 14 on the carrier 6 and capable of putting the product 14 into the passage 8.1. The product on the faulty carrier 6 can be grabbed and put into the passage 8.1 by the mechanical arm 9, so as to reduce the product remaining on the carrier 6, thereby facilitating the timely recovery management of the product and avoiding the problems of product omission and mixed loading of different batches.

[0035] Preferably, as shown in Figure 3 and Figure 4As shown, the upper surface of the turntable 3 has an annular groove 10, on which a sliding base 11 and a displacement actuator for driving the sliding base 11 to move are slidably fitted. The robotic arm 9 is mounted on the sliding base 11. The displacement actuator can be a motor-driven roller that abuts against the upper surface of the turntable, thereby allowing the sliding base 11 to move along the annular groove 10, thus driving the robotic arm 9 to move. By using the sliding base 11 to drive the robotic arm 9, the robotic arm can be moved arbitrarily to a position adjacent to the faulty carrier, facilitating the timely grabbing of products from the faulty carrier and transferring them through channel 8.1, preventing products from remaining on the carrier indefinitely. This robotic arm 9 is a conventional robotic arm in existing industrial automation equipment, and its structure will not be described in detail.

[0036] Preferably, such as Figure 5 As shown, an annular receiving tray 12 is provided below the turntable 3. The opening of the receiving tray 12 faces upward and is located below the channel 8.1. The receiving tray 12 is detachably connected to the turntable 3.

[0037] The turntable 3 has six or eight support units.

[0038] like Figure 3 and Figure 4 As shown, a protective cover 13 is provided in the middle of the turntable 3. One or more cameras are installed inside the protective cover 13 to monitor the working status of the vehicles in each working area in real time. When a product on one of the vehicles experiences abnormal displacement, or when the vehicle itself shifts position, the camera can promptly provide fault information, thereby controlling the rotation of the rotating base 7.1. This allows the faulty vehicle to be switched out in time, ensuring the smooth progress of subsequent product assembly. Preferably, the protective cover 13 is configured to allow light to pass through during the camera's image acquisition process. Specifically, the protective cover 13 is made of a transparent material.

[0039] Product 14 is a bearing housing.
