The solar frame cutting machine is provided with the automatic feeding device of the solar frame cutting machine and the cutting assembly 5, and the cutting assembly 5 is used for cutting a workpiece in a truncated mode.

As shown in fig. 1, the stock assembly 1 has a discharge end 13 and a discharge end 14, and a material (workpiece, i.e., profile) is placed from the discharge end 13 and is discharged from the discharge end 14. The stock assembly 1 comprises a mounting frame 16, two chain mechanisms are respectively arranged on two sides above the mounting frame 16, each chain mechanism comprises two chain wheels 17 (shown in figure 2), one chain wheel 17 is positioned near the discharging end 13, the other chain wheel 17 is positioned near the discharging end 14, the chain wheel 17 near the discharging end 13 is a free wheel, and the chain wheel 17 near the discharging end 14 is driven by a stepping motor. And a sensor is arranged near the discharge end 14, the sensor is connected with a controller, the controller is connected with a stepping motor, and when the sensor detects that the workpiece is arranged at the discharge end 14, the controller controls the stepping motor to stop running, and the workpiece is waited to be taken out of the discharge end 14 by the taking component 2. Two chain wheels 17 on each chain mechanism are sleeved with a conveying belt 11, the conveying belt 11 is a chain, the chain is meshed with the chain wheels, the conveying belt 11 can be driven by the chain wheels 17 near the discharging end 14 to rotate, and materials are conveyed from the discharging end 13 to the discharging end 14. As shown in fig. 2, a plurality of supporting blocks 12 are mounted on the conveyor belt 11, specifically, one supporting block 12 is mounted on each chain segment of the chain (i.e., the conveyor belt 11), the chain is specially designed so that each chain segment of the chain has an outwardly extending connecting plate, through holes are formed in the connecting plate, and the supporting blocks 12 are mounted on the chain segments through the through holes and bolts. In other embodiments, the conveyor belt 11 may be a belt, with the corresponding sprocket 17 replaced by a roller, and the support blocks mounted on the conveyor belt 11 in a conventional manner. As shown in fig. 2 and 4, the supporting block 12 has a first insertion groove 121, one side of the workpiece (solar frame profile) can be inserted into the first insertion groove 121, and then the supporting block 12 drives the workpiece to be transferred from the discharging end 13 to the discharging end 14 along with the operation of the conveyor belt 11, and how many pieces of workpieces to be processed can be stored in advance on the conveyor belt 11 above between the discharging end 13 and the discharging end 14, so the stock assembly 1 has the technical effect of being capable of storing a plurality of workpieces in advance. The workpiece is inserted in the corresponding two bearing blocks 12 on the chain mechanisms at the left side and the right side for transmission, so that the workpiece is more stable. And since the workpiece is inserted into the first insertion groove 121, the first insertion groove 121 has a gripping effect on the workpiece, so that the workpiece is stably transferred and is not damaged during the transfer. And because the first inserting groove 121 holds the workpiece, the space placement angle of the workpiece in the transmission process is not changed, so that the space placement angle of the workpiece is controlled in the whole process of transmitting the workpiece, and the workpiece is transmitted to the cutting assembly 5, so that the cutting assembly 5 can cut the workpiece in an accurate cutting direction (an oblique angle of 45 degrees is formed in the cutting process).

Further, as shown in fig. 2, the first insertion groove 121 has a wedge-shaped opening 1211, and the wedge-shaped opening 1211 facilitates the placement of the workpiece into the first insertion groove 121. As shown in fig. 2, the supporting block 12 is further provided with a supporting surface 122, and the supporting surface 122 can support another corner surface (as shown in fig. 4) of the workpiece (section bar). It can be seen that the design of the first insertion groove 121 and the bearing surface 122 in the bearing block 12 is designed in consideration of the structure of the solar frame profile, so that the bearing block 12 can stably and safely bear the workpiece. Further, a protection pad 123 is also mounted on the supporting surface 122, and the protection pad 123 has two functions: firstly, protecting the surface of a workpiece, and avoiding scratching the workpiece; second, if a plurality of sets of protection pads 123 with different thicknesses are reserved, the stock assembly 1 can be suitable for transporting a plurality of workpieces (profiles) with different sizes by replacing the protection pads 123. The support surface 122 is preferably provided with a protective pad 123, and in other embodiments, the support surface 122 may be used directly to support a workpiece.

As shown in fig. 5, a positioning rod 15 is provided outside the conveyor belt 11, the positioning rod 15 is a horizontal transverse rod, the length of the positioning rod 15 is approximately equal to the distance between the discharging end 13 and the discharging end 14, and the height of the positioning rod 15 is approximately the same as the height of the workpiece placed in the first insertion groove 121. When the work pieces are placed in the first insertion groove 121, one end of the work pieces is positioned by the positioning rod 15, which can align the work pieces on the stock assembly 1 with each other. Preferably, the positioning rod 15 is mounted on the side of the stock component 1 near the cutting component 5, and when the lengths of the workpieces on the stock component 1 are inconsistent, the workpiece on the stock component 1 is preferably aligned towards the end of the cutting component 5.

As shown in fig. 1, the take-up assembly 2 is disposed near the discharge end 14 of the stock assembly 1. As shown in fig. 3, the material taking assembly 2 includes a cross bar 22, two ends of one side of the cross bar 22 facing the material storing assembly 1 are respectively provided with a first manipulator 21, the first manipulators 21 are horizontally placed, the first manipulators 21 are pneumatic, and the first manipulators 21 are located near the material discharging end 14 of the material storing assembly 1; a transverse moving cylinder and a lifting cylinder are arranged near the middle position of the cross rod 22, the transverse moving cylinder can drive the cross rod 22 to horizontally move, the lifting cylinder can drive the cross rod 22 to vertically move, and the transverse moving cylinder and the lifting cylinder enable the cross rod 22 to drive the first manipulator 21 to move towards the stock assembly 1, grab a workpiece, move upwards, retreat, move downwards and put the workpiece into the feeding assembly 3, loosen a hand and retreat. The two first manipulators 21 are spaced apart to better grip long workpieces, which are located near the inner sides of the two conveyor belts 11, respectively.

As shown in fig. 3, in conjunction with fig. 5, the feeding assembly 3 includes a liftable cross frame 32, and a total of 4 rollers 31 are rotatably disposed on the cross frame 32, and the 4 rollers 31 are uniformly distributed over substantially the entire length of the cross frame 32.

The cross frame 32 is driven by a lifting cylinder to lift, so that the workpiece can be conveniently transported. The number of the rollers 31 is not necessarily four, and in other technical schemes, at least 1 roller 31 can be arranged; and at least one roller 31 among all the rollers 31 is driven to rotate by a motor. The first robot 21 places the workpiece gripped from the stock assembly 1 on the roller 31.

The invention realizes the synchronous rotation of a plurality of active rollers 31 through the gears 33 and the small toothed belts 34, and the workpiece has small mass and no need of large driving force, thus the workpiece transmission can be realized well by only one motor. In other technical solutions, the feeding assembly 3 may be further provided with a "belt transmission mechanism" as disclosed in CN106697921a, that is, a roller drives a conveyor belt to rotate, and the workpiece is placed on the conveyor belt.

As shown in fig. 5, the material extracting assembly 4 is disposed at one side (front side in the workpiece conveying direction) of the feeding assembly 3, and the material extracting assembly 4 can assist in feeding into the cutting assembly 5. As shown in fig. 5, when the feeding assembly 3 feeds the workpiece to the direction of the cutting assembly 5 through the roller 31, the feeding distance can be adjusted by changing the rotation number of the roller 31, a sensor can be arranged at the front end of the feeding direction of the feeding assembly 3, a controller is arranged at the front end of the feeding direction of the feeding assembly, the control end of the controller is connected with a motor for driving the roller 31, and when the sensor senses that the feeding assembly 3 feeds the workpiece to a certain distance, the motor is stopped by the controller, so that the workpiece is fed to a preset distance. By adjusting the position of the sensor, the part to be cut at the front end of the workpiece can be completely sent into the cutting assembly 5 for cutting, and the material pumping assembly 4 is not required. In this embodiment, a material extracting component 4 is further provided for assisting in feeding, so as to feed more efficiently and accurately. As shown in fig. 5, by setting the sensor as above, the feeding assembly 3 forwards conveys the workpiece to a certain distance, that is, the conveying is stopped, the material drawing assembly 4 is provided with a second manipulator 421, the second manipulator 421 is pneumatically and horizontally arranged, the second manipulator 421 moves to the front end of the workpiece, clamps the front end of the workpiece, continues to draw toward the cutting assembly 5 until reaching the position near the position where the workpiece can be cut, then the transverse frame 32 descends for a small distance, the workpiece is put down, and the cutting assembly 5 cuts the workpiece. The concrete structure of the material drawing assembly 4 is that the material drawing assembly 4 comprises a sliding rail 41 and a moving vehicle 42 which are arranged on the side of the cutting assembly 5, the sliding rail 41 is parallel to the feeding direction of the feeding assembly 3, the moving vehicle 42 is clamped on the sliding rail 41 through a linear bearing arranged on the moving vehicle 42, and the linear bearing can reduce the moving friction resistance of the moving vehicle 42 on the sliding rail 41.
