[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] like Figure 1-3As shown, a quantitative control conveying platform for flat tubes is applied to the re-inspection conveying production line of flat tubes, including a frame 1, on which a first conveying platform 9 for obliquely conveying flat tubes is arranged, the first conveying platform 9 includes a first fixed shaft 91 and a transmission shaft 92, and a plurality of chain transmission lines 93 are arranged between the first fixed shaft 91 and the transmission shaft 92. The frame 1 is also fixedly connected to a first servo drive motor 99, and the first servo drive motor 99 is used to drive the transmission shaft 92 to rotate. Each chain transmission line 93 includes a plurality of first sprockets 931 sleeved on the transmission shaft 91, and a plurality of second sprockets 932 sleeved on the first fixed shaft 91. The first sprockets 931 and the second sprockets 932 are connected by chains 933, and a plurality of pallets 94 are fixedly arranged on each chain 933 at intervals, and the pallets 94 are used to place flat tubes in batches. The pallet 94 is a right-angled trapezoidal structure, and the bottom edge of the pallet 94 is fixedly connected to the chain 933, and the flat tubes are placed on one side of the right-angle edge of the pallet 94. Therefore, when the first conveyor platform conveys the flat tube upward at an angle, the flat tube is placed horizontally on the chain transmission line and on a pallet placed horizontally. The side of the pallet in contact with the flat tube is perpendicular to the chain. Because the conveyor platform conveys upward at an angle, the flat tube is just leaning against the right-angled side of the pallet and will not collapse.

[0021] It should be noted that support rods 95 are provided on both sides or one side of the chain 933. The support rods 95 are provided along the conveying direction of the flat tube and are fixedly mounted on the first fixed shaft 91 and the transmission shaft 92. In addition, a plurality of fixed rods 96 are provided on the frame 1. The fixed rods 96 are provided below the chain 933. The fixed rods 96 and the chain 933 are arranged perpendicularly. The fixed rods 96 are fixedly connected to the frame through fixed brackets 961. A plurality of threaded holes are provided upward on each fixed rod 96. The support rods 97 are fixedly connected to the fixed rods 96 by screws. Thus, the flat tube is placed horizontally on the chain. If the flat tube is long, it can be mounted horizontally between two or more transmission chains, that is, it can be mounted horizontally on multiple chain transmission lines.

[0022] As shown in the figure, a sprocket adjusting device is also provided on the frame 1, and the sprocket adjusting device includes a third sprocket 98 and a bracket. The chain 933 includes an upper running chain 961 and a lower running chain 962. The third sprocket 991 is arranged between the running chain 961 and the lower running chain 962, and is located on the lower running chain 962. One end of the bracket 992 is fixedly connected to the fixing rod 96, and the other end of the bracket is drivingly connected to the third sprocket 991.

[0023] A second conveying platform 2 for conveying flat tubes is arranged on the frame 1, a connecting seat 3 is arranged above the conveying platform, and a plurality of flip ring plates 4 are arranged on one side of the connecting seat 3 close to the output end of the second conveying platform. The flip ring plates 4 are used to flip the flat tubes from the front side to the back side.

[0024] Therefore, by arranging a second conveying platform on the frame, arranging a connecting seat above the conveying platform, and arranging a flip ring plate on the connecting seat, the flat tube to be inspected is flipped from the front side to the back side, thereby facilitating the front and back side inspection of the flat tube.

[0025] To further illustrate, the second conveying platform 2 includes a first driven rotating shaft 21 and a first driving rotating shaft 22 arranged in parallel, the first driven rotating shaft 21 and the first driving rotating shaft 22 are horizontally fixedly arranged on the frame 1, a conveyor belt 22 is arranged on the outer surface of the first driven rotating shaft 21 and the first driving rotating shaft 22, the first driving rotating shaft 22 is connected to a second servo driving motor 23, the second servo driving motor 23 is fixedly installed on the frame 1 through a motor seat, a sprocket is arranged at one end of the first driving rotating shaft 22, the second driving rotating shaft of the second servo driving motor 23 drives the first driving rotating shaft 22 to operate through a chain and a sprocket, and the rotating shaft close to the output end of the second conveying platform 2 is the first driving rotating shaft 22. Thus, the smooth transportation of the flat tube is achieved.

[0026] like Figure 1 As shown, the second conveyor platform 2 includes multiple conveyor lines, and the first driven shaft 21 is parallelly provided with multiple first transmission bearings 23 along its length direction, and the outer surface of each first transmission bearing 23 is connected to the first driving shaft 22 through a corresponding conveyor belt to form multiple conveyor lines. Therefore, by arranging multiple conveyor lines on the frame, each conveyor line can synchronously convey the flat tube through a driving motor, which greatly improves production efficiency and saves energy. It should be noted that if the size of the flat tube is relatively short, it can be conveyed by one conveyor belt; if the size of the flat tube is relatively long, it can be conveyed horizontally on two conveyor belts.

[0027] It should be noted that the frame 1 is also provided with a belt tension adjustment device 3, which includes a fluid wheel tensioning shaft 31 and a plurality of adjusting fluid wheels 32 arranged on the fluid wheel tensioning shaft 31. The two ends of the fluid wheel tensioning shaft 31 are fixedly connected to the frame 1, and each adjusting fluid wheel 32 is arranged in parallel and rotatably connected to the fluid wheel tensioning shaft 31 through a corresponding connecting frame. The conveyor belt includes an upper conveyor belt 24 and a lower conveyor belt 20, and the adjusting fluid wheel 32 is located on the upper surface of the lower conveyor belt 20. Under normal circumstances, the conveyor belt is made of PVC. During use, the belt will become loose, and thus, the fluid wheel tensioning shaft and the adjusting fluid wheel 32 are used to adjust the tension of the conveyor belt.

[0028] It should be noted that the flip ring plate 4 includes a horizontal portion 41 and an arc-shaped curved portion 42. One end of the horizontal portion 41 is fixedly connected to the connecting seat 3 through a connecting rod, and the other end of the horizontal portion 41 is an arc-shaped curved portion 42. The arc-shaped curved portion 42 is curved along the outer curved surface of the first active rotating shaft 22. A reserved distance is set between the outer curved surface of the first active rotating shaft 22 and the arc-shaped curved portion 42. The reserved distance is used for passing the flat tube. The distance between the horizontal portion 41 and the upper conveyor is the reserved distance h1, and the height of the flat tube is h2. The reserved distance h1 is greater than the height h2 of the flat tube. In this way, the flat tube can be smoothly flipped from the flip ring plate.

[0029] At the same time, the frame 1 is also provided with a third conveying platform 5 for horizontally conveying the flat tubes, and the third conveying platform 5 is located below the output end of the second conveying platform 2. After the flat tubes are conveyed to the turning plate 4 by the second conveying platform 2, the flat tubes are turned over from the front side to the back side along the arc-shaped curved portion, and then slide down to the third conveying platform 5. Therefore, the front side inspection can be performed on the second conveying platform, and the back side inspection can be completed on the third conveying platform.

[0030] As shown in the figure, the horizontal parts of the connecting rod and the flip ring plate 4 are located in the same plane, a plurality of bolt holes are provided on the connecting rod, a connecting slot hole 43 is provided on the horizontal part 41, and the connecting rod and the flip ring plate 4 are fixedly connected by bolts passing through the connecting slot hole 43 and the bolt hole 44. Therefore, by providing a plurality of bolt holes for the flip ring plate to select, the flip ring plate can select a suitable bolt hole according to the size of the flat tube, etc., to realize the connection between the flip ring plate and the connecting rod.
