[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see Figures 1-5 This invention provides a technical solution: a BC module high-antioxidant manifold bending device, including a mounting plate 100. A sliding tube 200 is slidably connected to one end of the middle of the mounting plate 100. The sliding tube 200 and the mounting plate 100 are connected by a T-shaped slider and a groove to form a sliding constraint. A groove is opened at the bottom of the sliding tube 200. T-shaped sliders are distributed on the mounting plate 100. This is prior art. Other limiting sliding structures can also be used, which will not be described in detail here. A fixed tube 300 is slidably connected to one end of the sliding tube 200. One end of the fixed tube 300 is fixed to the other end of the middle of the mounting plate 100. The end of the fixed tube 300 away from the sliding tube 200 is welded to the other end of the middle of the mounting plate 100. It is necessary to ensure that the sliding tube 200 and the fixed tube 300 are on the same straight line and slide smoothly. The mounting plate 100, the sliding tube 200 and the fixed tube 300 are all made of stainless steel. A flange 400 is fixed to the end of the fixed tube 300. The sliding tube 200 is welded to the end of the fixed tube 300. Limiting plates 500 are fixed at the middle of both ends of the sliding tube 200. The limiting plates 500 are welded to the sliding tube 200. A sliding rod 600 passing through the limiting plate 500 is vertically fixed at the middle of the flange 400. The outer side of the sliding rod 600 is coated with lubricating oil. A limiting pulley 700 is connected to the end of the sliding rod 600 near the limiting plate 500, and the outer side of the sliding rod 600 is sleeved between the limiting pulley 700 and the limiting plate 500. A reset component 800 is provided, which is a stainless steel spring. A trigger component 900 is rotatably connected to the outer side of the sliding tube 200 at the position corresponding to the limit pulley 700. A starting component 1010 for driving the trigger component 900 to rotate is fixed at the top of the sliding tube 200. A bending opening 1020 is opened at the other end of the sliding tube 200. The bending opening 1020 is formed by cutting with a cutting machine. A bending component 1030 is provided at the bending opening 1020 of the sliding tube 200.
[0026] In use, the busbar enters through the fixed tube 300, passes through the sliding tube 200 and the bending assembly 1030, and exits through the bending opening 1020. During bending, the starting assembly 1010 is activated first. The operation of the starting assembly 1010 drives the trigger assembly 900 to rotate clockwise. During the clockwise rotation of the trigger assembly 900, the reset member 800 is compressed. Since the position of the slide rod 600 is fixed, the sliding tube 200 is moved away from the fixed tube 300, so that the conveyed busbar will not be affected during the bending process, and it can be bent continuously, thereby improving efficiency. At the same time, the trigger assembly 900 drives the bending assembly 1030 to bend the busbar.
[0027] Please see Figure 1 and Figure 2 The triggering component 900 includes a drive wheel 901 rotatably connected to the sliding tube 200 at the position corresponding to the limiting pulley 700. A drive trigger block 902 is obliquely fixed to the top of the outer ring of the drive wheel 901. One side of the drive trigger block 902 is slit and the other side is arc-shaped. The slit faces the bending component 1030 and the arc-shaped side faces the limiting pulley 700. When the drive trigger block 902 rotates, it drives the bending component 1030 to rotate. A transition block 903 is obliquely fixed to the bottom of the outer ring of the drive wheel 901, and a toothed ring 904 is sleeved on the inner ring of the drive wheel 901. The toothed ring 904 meshes with the starting component 1010. The extended edge line of the drive trigger block 902 coincides with the extended edge line of the transition block 903. The included angle between the two ends of the transition block 903 is 90°, so that the contact time between the transition block 903 and the limiting pulley 700 can make the bending component 1030 rotate to a right angle.
[0028] In use, the starting component 1010 drives the gear ring 904 to rotate clockwise, which in turn drives the drive wheel 901 to rotate clockwise. The clockwise rotation of the drive wheel 901 drives the drive trigger block 902 and the transition block 903 to rotate clockwise together. The rotation of the drive trigger block 902 contacts the bending component 1030, causing the bending component 1030 to rotate counterclockwise, thereby completing the bending. The rotation of the transition block 903 contacts the limiting pulley 700, compressing the limiting pulley 700. Due to the obstruction of the limiting plate 500, the limiting pulley 700 will cause the sliding tube 200 to move away from the fixed tube 300 when compressing the reset component 800.
[0029] Please see Figures 1-5The bending assembly 1030 includes a roller 1031 disposed within a bending opening 1020. The roller 1031 has a busbar inlet 1032 extending through both ends for the busbar to pass through. A stop block 1033 is vertically fixed to one side of the bottom end of the bending opening 1020. Sliding tubes 200 extend from both ends of the roller 1031 and are connected to a rotating shaft 1034. A driven wheel 1035 is sleeved on the outside of the rotating shaft 1034. A return spring 1036, a type of coil spring, is connected between the outside of the rotating shaft 1034 and the outside of the sliding tube 200, and can drive the rotating shaft 1034 to... Returning to the initial position without external force, the driven wheel 1035 tilts at the top, driving the trigger block 902 to one side, where a driven trigger block 1037 is fixed. When the driving trigger block 902 rotates, it contacts the driven trigger block 1037, causing the driven wheel 1035 to rotate. The distance from which the transition block 903 contacts the limit pulley 700 is the same as the distance from which the driving trigger block 902 contacts the driven trigger block 1037. The angle between the extension line of the driven trigger block 1037 and the extension line of the driving trigger block 902 is 90°, which is the angle of the initial position. It can also be designed to be other angles, but attention should be paid to the travel.
[0030] In use, the clockwise rotation of the moving trigger block 902 contacts the driven trigger block 1037, causing the driven trigger block 1037 to rotate along with it. The driven trigger block 1037 rotates counterclockwise, compressing the return spring 1036. The counterclockwise rotation of the driven trigger block 1037 synchronously drives the driven wheel 1035 and the rotating shaft 1034 to rotate counterclockwise, which in turn drives the roller 1031 to rotate counterclockwise around the rotating shaft 1034. The rotation of the roller 1031 causes the busbar inlet 1032 to bend. After the roller 1031 bends the busbar onto the stop block 1033, the starting component 1010 is activated to return to the initial position. After the return spring 1036 recovers its deformation, it drives the driven wheel 1035 back to its original position.
[0031] Please see Figure 1 , Figure 2 and Figure 5 The starting component 1010 includes a telescopic component 1011 fixed to one side of the top end of the sliding tube 200. The telescopic component 1011 can be a cylinder or an electric push rod. The specific model is selected according to the actual use. It is existing technology and will not be described in detail here. A rack 1012 is connected between the output end of the telescopic component 1011 and the top of the gear ring 904. The rack 1012 meshes with the gear ring 904.
[0032] In use, the telescopic component 1011 extends and retracts, causing the rack 1012 to move towards the drive wheel 901, and the gear meshing causes the gear ring 904 on the drive wheel 901 to rotate.
[0033] Please see Figure 1 and Figure 2A shearing blade 1040 is vertically fixed on one side of the top of the bending opening 1020, and a trigger switch 1070 is fixed on the outside of the sliding tube 200. The trigger switch 1070 is electrically connected to the shearing blade 1040.
[0034] Note: The shearing blade 1040 and the trigger switch 1070 are for additional configuration use, that is, to cut independently. Alternatively, the shearing blade 1040 can be used horizontally to work together. This application only shows the case of using them independently.
[0035] Please see Figure 1 , Figure 3 and Figure 5 A fixing plate 1050 with a limiting fixing tube 300 and a sliding rod 600 is vertically fixed on the mounting plate 100 to increase reliability.
[0036] Please see Figure 3 Electric rollers 1060 are distributed inside both the sliding tube 200 and the fixed tube 300. The electric rollers 1060 are existing technology. The specific model is selected according to the actual use and is used for conveying the busbar.
