[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] See also Figure 1-Figure 3 The present embodiment discloses a multifunctional assembly line for conveying and positioning brake discs, including a product outlet layer 1 and a product return layer 2 which are distributed in an upper and lower manner. The product outlet layer 1 is arranged above the product return layer 2. The product outlet layer 1 is used to convey the preliminarily processed products to the outside of the line for inspection. The product return layer 2 is used for conveying and centering the inspected products. The product outlet end of the product outlet layer 1 corresponds to the product inlet end of the product return layer 2, which is convenient for connecting the two processes.

[0022] Specifically, the product return line layer 2 includes a return line support frame 21 and a plurality of return line conveying rollers 22 connected through the return line support frame 21, and the product outlet line layer 1 includes an outlet line support frame 11 fixedly connected to the top of the return line support frame 21 and a plurality of outlet line conveying rollers 12 connected through the outlet line support frame 11. The main bodies of the return line support frame 21 and the outlet line support frame 11 are supported by square tubes, and channel steel is used as a frame to build the frame.

[0023] The end of the loop support frame 21 is connected to a positioning mechanism 3 for product positioning and centering. The processed product is placed at the entrance end of the product outlet layer 1 by a staff member or a robot, and then transported to its outlet end by the outlet conveyor roller 12. The staff or the robot performs size and appearance inspection on the product out of the outlet line. After the inspection, the product is placed at the entrance end of the product loop layer 2, and the loop conveyor roller 22 transports the product to the positioning mechanism 3. After positioning and centering, the robot can accurately grasp the product and carry out subsequent processing.

[0024] In this embodiment, both the product outlet layer 1 and the product return layer 2 adopt a connection structure without a driving mechanism. The top mounting surface of the return support frame 21 is inclined relative to the horizontal plane, so that the return conveying roller 22 installed thereon has a certain slope, and the conveying entrance end is the high point; the top mounting surface of the outlet support frame 11 is inclined relative to the horizontal plane, so that the outlet conveying roller 12 installed thereon has a certain slope, and the conveying entrance end is the high point. When the product is placed at the conveying entrance end, the product can be driven down by the conveying roller. It can be understood that the inclination direction of the top mounting surfaces of the return support frame 21 and the outlet support frame 11 should be set in the opposite direction so that the two processes can be connected with each other. By setting a connection structure without a driving mechanism, it is possible to save operating energy consumption and reduce costs.

[0025] In the product loop layer 2, in order to prevent the product from being offset in the process of sliding down by itself and affecting the subsequent centering, in this embodiment, the loop support frame 21 is also connected with a guide mechanism 5, which is arranged at the front end of the positioning mechanism 3, including two guide rods 51 arranged in an eight-shaped shape, and a number of bearings (not shown in the figure) are fixedly connected along the length direction of the guide rods 51, and the bearings are used for conveying and guiding the product. The front end of the guide rod 51 is connected to the side end bracket of the loop support frame 21 through a connecting block 52, and the middle end or rear end of the guide rod 51 is connected between the two side end brackets through a support rod 53 arranged below it. In order to make the spacing between the two guide rods 51 adapt to products of different specifications, the guide mechanism 5 also includes a guide rod adjustment member for adjusting the spacing between the guide rods 51. In this embodiment, the guide rod adjustment member includes a screw, and the support rod 53 is constructed as a screw, which is rotatably connected between the two side end brackets, one end of the screw passes through the side end bracket and is connected to a hand wheel, and the screw is respectively connected to the two guide rods 51 through a nut seat 54. The spirals of the two nut seats 54 are arranged in opposite directions, and by turning the hand wheel, the two nut seats 54 can be driven to move in opposite directions, thereby adjusting the distance between the two guide rods 51. Correspondingly, the front end of the guide rod 51 is movably connected to the connecting block 52 to support the angle adjustment of the guide rod 51.

[0026] See also Figure 3 The positioning mechanism 3 includes a mounting plate 31 fixedly connected to the loop support frame 21. The mounting plate 31 is arranged below the loop conveying roller 22, and its length corresponds to the length of the loop conveying roller 22. The top of the mounting plate 31 is provided with two movable groups of clamping seats 32 and a clamping rod 33 connected to the top of the clamping seat 32. The top of the clamping rod 33 extends above the loop conveying roller 22. Two clamping rods 33 at a certain distance are fixedly connected to each group of clamping seats 32. The two groups of clamping seats 32 are constructed to be able to move toward or in the opposite direction to change the distance between the two clamping seats 32, so that the clamping rod 33 can clamp and position the product. Preferably, a rotating bearing can be sleeved on the top of the clamping rod 33 to avoid jamming of the clamping rod 33 when clamping.

[0027] In order to realize automatic centering and positioning, in this embodiment, the positioning mechanism 3 further includes a driving part for driving the two clamping seats 32 to move. Specifically, the driving part includes two sets of slide rails 34 fixedly connected to the top of the mounting plate 31 and staggeredly distributed. The slide rails 34 are arranged along the length direction of the mounting plate 31, and the clamping seats 32 are connected to the two sets of slide rails 34 through sliders 35. The two sliders 35 located on the inner side are respectively connected to rack connecting seats 36, and the inner sides of the two rack connecting seats 36 are respectively connected to oppositely arranged racks 37. A gear 38 is meshed and connected between the two racks 37, and the gear 38 is fixedly connected to the connecting shaft at the center of the mounting plate 31 through a bearing. Then, pushing the clamping seat 32 on one side can drive the clamping seat 32 on the other side to produce synchronous movement, so that the two sets of clamping rods 33 can move synchronously towards each other, and the four clamping rods 33 simultaneously contact the brake disc product to realize the centering of the brake disc. Compared with the traditional method of positioning by setting a positioning rod at the center of the brake disc, the positioning structure has better stability and accuracy.

[0028] Furthermore, the driving part also includes a telescopic cylinder 39 fixedly connected to the bottom end of the mounting plate 31, and the telescopic cylinder 39 is arranged along the length direction of the mounting plate 31. The piston rod end of the telescopic cylinder 39 is fixedly connected with a driving block 40, and the driving block 40 passes through the mounting plate 31 and is fixedly connected to one of the clamping seats 32 or the slider 35. Correspondingly, the mounting plate 31 is provided with an opening 41 that cooperates with the movement of the driving block 40. The telescopic movement of the telescopic cylinder 39 drives one of the clamping seats 32 to move, and then the cooperation of the gear 38 and the rack 37 drives the other clamping seat 32 to move synchronously.

[0029] Preferably, in order to control the movement stroke of the clamping seat 32 and the clamping rod 33, the side end of one of the clamping seats 32 is also fixedly connected to a photoelectric probe 42, and correspondingly, the top of the mounting plate 31 is connected to a manual slide 43, and the slide 43 adopts a ball screw structure, and the nut end of the slide 43 is fixedly connected to a photoelectric mounting plate 44, and a photoelectric sensor 45 that cooperates with the photoelectric probe 42 is fixedly connected to the photoelectric mounting plate 44. The retraction stroke of the clamping rod 33 can be controlled by adjusting the position of the photoelectric mounting plate 44 and the photoelectric sensor 45.

[0030] In actual application, the robot is used to grab the brake disc product that has been accurately positioned. Since the robot adopts an electromagnet grabbing structure, in order to avoid its suction affecting the subsequent brake disc position, and also to avoid multiple brake discs being stuck together, in this embodiment, the loop support frame 21 is connected with a first sensor at a position close to the positioning mechanism 3. Correspondingly, at least two brake cylinders 6 are fixedly connected to the front end of the loop support frame 21 to prevent product accumulation. When the product is about to enter the position of the positioning mechanism 3, the first sensor starts the brake cylinder 6 through signal transmission, slowing down or stopping the running speed of the front product, ensuring that there is only one brake disc at the position of the positioning mechanism 3. After the robot grabs the brake disc at the positioning mechanism 3, the brake cylinder 6 is released to allow the next brake disc to enter the positioning mechanism 3. In this embodiment, the brake cylinder 6 is preferably a three-axis cylinder, and a nylon push block is connected to the push plate of the three-axis cylinder. When the three-axis cylinder is extended, the nylon push block is in close contact with the conveying roller, blocking the rotation of the conveying roller, thereby achieving a braking effect. A second sensor is also connected to the position corresponding to the positioning mechanism 3. When the product enters the position of the positioning mechanism 3, the signal of the second sensor is transmitted to start the telescopic cylinder 39 of the positioning mechanism 3, driving each clamping rod 33 to move to center the product. It can be understood that the outlet support frame 11 can also be connected to the brake cylinder according to the actual operation speed to ensure the orderly progress of the conveying operation.

[0031] In this embodiment, the multifunctional assembly line further includes a defective product outlet layer 7 fixedly connected to the top of the outlet support frame 11, and the defective product outlet layer 7 is used for conveying the initially processed defective products. The defective product outlet layer 7 includes a defective product support frame 71 and a plurality of defective product conveying rollers 72 connected by the defective product support frame 71, and the top mounting surface of the defective product support frame 71 is inclined in the same direction as the outlet support frame 11. The initially processed defective products are placed at the entrance end of the defective product outlet layer 7 by staff or robots, and the products flow along the slope to the exit end position, and the staff or robots clear the products in the line, and the ends of the outlet support frame 11 and the defective product support frame 71 are connected with nylon baffles to block the products.

[0032] The multifunctional assembly line provided by the utility model adopts a three-layer inspection line, which can realize the out-line conveying of qualified and unqualified products after initial processing, as well as the return line conveying and centering positioning of qualified products after appearance inspection. The product out-line layer 1 is used to flow qualified products out of the line, and further inspect the product size and appearance by manual or robot. The products after inspection are placed in the product return line layer 2. The product return line layer 2 is used to return the inspected products to the line. The end positioning mechanism 3 positions the products in the return line. The robot grabs the positioned products for automatic palletizing. The unqualified product out-line layer 7 is used to flow unqualified products out of the line. The utility model solves the problem of inaccurate positioning after the product returns by setting the product return line layer 2 connected with the product out-line layer 1, and further setting the guide mechanism 5 and the positioning mechanism 3, so as to ensure that the position of each brake disc is accurate, and the robot will not collide with the machine. The brake cylinder can realize the orderly separation and orderly conveying of the brake disc; and the setting of the unqualified product out-line layer 7 further improves the comprehensiveness of the assembly line function.
