[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] (1) By setting up a packaging heat sealing device, the following technical effects are produced:

[0031] First, a passage is provided between the conveyor belt 1 of the packaging heat sealing device and the conveyor belt 2 of the positioning and pushing device to allow the brake disc to pass through. After the brake disc passes through the passage and enters the packaging bag, it stays on the conveyor belt 1. The conveyor belt 1 not only realizes the quantitative conveying and supply of the packaging bag, but also realizes the directional conveying of the brake disc, which has a multifunctional effect.

[0032] Secondly, a vacuum generator and a heating plate are arranged above the conveyor belt 1 of the packaging heat sealing device. The vacuum generator and the heating plate run alternately on the brake disc of the conveyor belt 1, and the conveyor belt has the effect of positioning and supporting the brake disc. At the same time, the operation of the conveyor belt 1 has the effect of quantitative transportation of the turnover conveying device.

[0033] (2) By setting up a turnover conveying device, the following three technical effects are produced:

[0034] First, the turnover conveyor device is provided with an arc-shaped support, and the arc-shaped support rotates along the column. The outer side of the column is provided with a torsion spring connected to the arc-shaped support. The arc-shaped support overcomes the rotation of the torsion spring and has the effect of buffering the moving brake disc;

[0035] Secondly, the turnover conveying device is provided with a locking assembly detachably connected to the arc support. When the arc support is rotated to a certain angle, the arc support is locked by the locking assembly. Through the cooperation between the arc support and the locking assembly, the brake disc is adjusted and locked.

[0036] Third, a flexible rubber magnetic strip is arranged inside the arc support, and the inner diameter of the flexible rubber magnetic strip is slightly smaller than the outer diameter of the brake disc. The expansion of the flexible rubber magnetic strip further cushions the impact of the brake disc on the arc support. At the same time, the suction of the flexible rubber magnetic strip and the cooperation of the arc support make the flexible rubber magnetic strip have better fixing and cushioning effect on the brake disc. Moreover, since the flexible rubber magnetic strip can expand, it can adapt to the turnover of brake discs with various outer diameters. The adaptability of the brake disc turnover conveying device is very strong.

[0037] (3) By setting up the plate swing device, the following two technical effects are produced:

[0038] First, the swing plate device is provided with a positioning component. The positioning component is provided with two parallel Z-axis linear slides. The two Z-axis linear slides are connected by a connecting shaft. An X-axis linear slide is provided between the two Z-axis linear slides. The up and down movement of the Z-axis linear slide not only plays a role in conveying the brake disc, but also plays a role in positioning the brake disc in combination with the operation of the X-axis linear slide.

[0039] Secondly, a blanking assembly is provided on the X-axis linear slide. When the Z-axis linear slide descends above the pallet, the blanking assembly drives the brake disc on the pallet to the set position on the pallet through cylinder four, and then drives the pallet to rotate through cylinder five to remove the brake disc. Through the operation of the Z-axis linear slide and the X-axis linear slide in the positioning assembly, the blanking assembly achieves a higher plate swing accuracy and a more stable plate swing operation.

[0066] A method for using a production line for automatic packaging and placing brake discs, comprising the following steps:

[0067] S1: Control conveyor belt 1 and conveyor belt 2 through the PLC controller to convey the brake disc and packaging bag 8 to the position of the through port 13 and stop;

[0068] S2: Start the second cylinder 111, which drives the vacuum generator 112 down until the suction port of the vacuum generator 112 contacts the upper side of the packaging bag 8. The vacuum generator 112 is started to suck the upper side of the packaging bag 8. The second cylinder 111 retracts and drives the vacuum generator 112 up to separate the two sides of the packaging bag 8.

[0069] S3: Activate cylinder 1 22, which drives push plate 1 21 to push the brake disc into the packaging bag 8, and then the telescopic end of cylinder 1 22 retracts and returns to its original position;

[0070] S4: Start the third cylinder 121, which drives the heating plate 122 down until it contacts the opening of the packaging bag 8. The heating plate 122 is started and seals the brake disc in the packaging bag 8. The heating plate 122 is then stopped and driven up and reset by the third cylinder 121.

[0071] S5: Start conveyor belt 2 2, which conveys the packaged brake disc forward. Due to the friction and inertia of the conveyor belt, the brake disc is brought into contact with the arc-shaped support 61 on the turnover conveyor device. Under the adsorption of the flexible rubber magnetic strip 664, the brake disc overcomes the torsion force of the torsion spring at one end of the arc-shaped support 61 and drives the arc-shaped support 61 to rotate together. When the brake disc rotates to contact the locking assembly 66, it is locked in position by the locking assembly 66. At this time, the arc-shaped support 61 is facing the direction of the swing plate device.

[0072] S6: Start the cylinder 67, which drives the arc push plate 64 to extend through the support rod 65, pushing the brake disc in the arc support 61 onto the support plate 51 of the blanking assembly 5;

[0073] S7: Start the motor 1 311 and the motor 2 321, and transport the brake disc to the set position above the tray 7 through the cooperation of the X-axis linear slide 32 and the Z-axis linear slide 31, combined with the extension and retraction of the cylinder 4 52;

[0074] S8: Start cylinder five 55, the telescopic end of cylinder five 55 retracts, and drives the support plate 51 to rotate and tilt, and the brake disc slides to the set position on the tray 7, and repeats steps S1-S8 to place the brake disc at the set position on the tray 7, completing the brake disc swinging.

[0075] The specific working process of the present invention is:

[0076] During use, the PLC controller is used to set the interval running time of conveyor belt 1 and conveyor belt 2, the extension and retraction time of cylinder 2 111 and cylinder 3 121, the start time of vacuum generator 112 and heating plate 122, the extension and retraction time of cylinder 1 22 and cylinder 6 67, and the position of positioning component 4 is set by starting and stopping motor 1 311, motor 2 321 and cylinder 4 52, and the angle of support plate 51 is controlled by the extension and retraction time of cylinder 5 55.

[0077] The PLC controller controls the conveyor belt 1 and the conveyor belt 2 to convey the brake disc and the packaging bag 8 to the through-port 13 and stop. The conveyor belt 1 not only realizes the quantitative conveying and supply of the packaging bag 8, but also realizes the directional conveying of the brake disc.

[0078] Start the second cylinder 111, which drives the vacuum generator 112 down until the suction port of the vacuum generator 112 contacts the upper side of the packaging bag 8. Start the vacuum generator 112 to suck the upper side of the packaging bag 8. The second cylinder 111 retracts and drives the vacuum generator 112 to slowly rise, separating the two sides of the packaging bag 8. Since the packaging bag 8 is a bag with a certain weight, when the vacuum generator 112 slowly sucks one side of the packaging bag 8 together, the packaging bag 8 can be opened, and the sucked side of the packaging bag 8 is fixed at the same time to facilitate the entry of the brake disc.

[0079] Start the cylinder 22, which drives the push plate 21 to push the brake disc into the packaging bag 8, and then the telescopic end of the cylinder 22 retracts and returns to its original position;

[0080] Start the third cylinder 121, which drives the heating plate 122 down until it contacts the opening side of the packaging bag 8, and then starts the heating plate 122 to seal the brake disc in the packaging bag 8. Then, stop the heating plate 122, and drive the heating plate 122 up and back to its original position by the third cylinder 121;

[0081] When the vacuum generator 112 and the heating plate 122 are in operation, the conveyor belt 1 plays the role of positioning and supporting the brake disc. At the same time, the operation of the conveyor belt 1 also plays the role of quantitatively conveying the brake disc to the turnover conveying device.

[0082] Start conveyor belt 2 2, which conveys the packaged brake disc forward. Under the action of the friction and inertia of the conveyor belt, the brake disc is brought into contact with the arc-shaped support 61 on the turnover conveyor device. Since the diameter of the flexible rubber magnetic strip 664 in the free state is slightly smaller than the diameter of the brake disc, when the brake disc impacts the flexible rubber magnetic strip 664, the side expansion and deformation of the flexible rubber magnetic strip 664 can buffer the brake disc. After the brake disc is buffered, the flexible rubber magnetic strip 664 sucks and fixes the brake disc. Under the adsorption and fixation of the flexible rubber magnetic strip 664, the brake disc overcomes the torsion force of the torsion spring at one end of the arc-shaped support 61 and drives the arc-shaped support 61 to rotate together. When it rotates to contact with the locking component 66, it is locked in position by the locking component 66. At this time, the arc-shaped support 61 faces the direction of the swing plate device, and the direction adjustment action of the brake disc is stably completed.

[0083] The air cylinder 67 is activated, and the air cylinder 67 drives the arc push plate 64 to extend through the support rod 65. The arc push plate 64 passes through the through hole of the arc support 61 and pushes the brake disc in the arc support 61 onto the support plate 51 of the blanking assembly 5. At the same time, the support rod 65 carries the wedge block 652 on the release rod 651 and inserts it into the wedge groove of the limit pin 662, driving the limit pin 662 to slide and retract in the guide groove 661, thereby separating the boss 612 from the limit pin 662.
