DETAILED DESCRIPTION

[0019] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The present invention provides a technical solution: photovoltaic cable automated production equipment, including a fixing plate 1, the fixing plate 1 is evenly provided with through holes, and a semicircular jacket 11 is installed inside the through hole, a cable protective sleeve 2 is clamped and installed inside the semicircular jacket 11, and the cable protective sleeve 2 is filled with a thin cable 21. A power-on test device 3 is arranged on one side of the fixing plate 1. When testing whether the photovoltaic cable can be powered on, firstly, each cable protective sleeve 2 to be tested is inserted between two semicircular jackets 11 in the circumferential direction, so that the semicircular jacket 11 fixes the position of the cable protective sleeve 2. At this time, the power-on test device 3 is used to perform a power-on test, and the test process is simple and convenient;

[0021] The power-on test device 3 includes an intermediate cable 33, an internal power-on circuit of the intermediate cable 33 is provided, and the power-on circuit is electrically connected to a current sensor 331, and both ends of the intermediate cable 33 are provided with wiring terminals 332, and the wiring terminals 332 are electrically connected and matched with the thin cable 21, and one end of the cable protective cover 2 is electrically connected to a power-on test head 37, when the power-on test is performed, the two wiring terminals 332 located at both ends of the intermediate cable 33 are combined with the two thin cables 21 and can be powered, and only one of the thin cables 21 needs to generate a voltage for the test, and the current sensor 331 reads the current size to determine whether the two thin cables 21 are currently faulty, and this method can quickly test the conductivity of the thin cables 21 when they are connected end to end, and the test process is efficient. Compared with powering on together, this method does not require a large input current, and the test safety is high;

[0022] The middle outer wall of the intermediate cable 33 is sleeved with a ball nut seat 31, and a screw rod 34 is movably penetrated by a thread on one side of the ball nut seat 31, and the power circuit of the intermediate cable 33 bypasses the position where the screw rod 34 is penetrated. A motor 35 is arranged on one side of the fixed plate 1, and the output end of the motor 35 is movably connected with the screw rod 34 through a coupling. The two sides of the ball nut seat 31 are correspondingly fixed with side plates 311 by welding, and a guide rod 36 is arranged on one side of the fixed plate 1. The guide rod 36 is movably inserted into the inner wall of the side plate 311. When testing, the screw rod 34 is driven to rotate by the motor 35. When the angle of the intermediate cable 33 is limited, the ball nut seat 31 can be driven to move in parallel to connect and disconnect the current. When the angle of the intermediate cable 33 is not limited, the circumferential angle can be adjusted to test another group of cables 33, achieving the function of time-sharing multiplexing of steering and translation, without the need for conventional rotating cylinders and other components, saving costs;

[0023] The number of guide rods 36 is several pairs and they are distributed in a circle. An electric push rod 361 is provided at one end of the guide rod 36. A split part 362 is connected to one end of the electric push rod 361. When the electric push rod 361 is in an extended state, the split part 362 is in an extended state. At this time, the ball nut seat 31 will move to the leftmost end as the screw rod 34 rotates. At this time, the electric push rod 361 is contracted, and the split part 362 is in a contracted state and detached from the side plate 311. Since the rotation of the ball nut seat 31 is unhindered, it will rotate with the rotation of the screw rod 34. When it reaches a suitable position, the split part 362 of another group of guide rods 36 is in a stretched state again, and it can only move in parallel, which is convenient for controlling the timing of its parallel movement.

[0024] A magnet block 312 is installed on one side of the ball nut seat 31, and an electromagnetic top block 32 is installed on one end of the screw rod 34. The electromagnetic top block 32 and the magnet block 312 are magnetically attracted to each other. When the ball nut seat 31 is driven to translate to the leftmost end, the electromagnetic top block 32 is energized, and it is magnetically attracted to the magnet block 312. At this time, when the screw rod 34 is driven to rotate, the ball nut seat 31 and the middle cable 33 can be driven to rotate. When it rotates to other angles, the electromagnetic top block 32 is powered off. At this time, the ball nut seat 31 will not rotate with the rotation of the screw rod 34, so that the rotation and translation switching are convenient;

[0025] After testing one group of cables, the semicircular jacket 11 is loosened to loosen the tested middle cable 33, and at the same time another group of cable protective jackets 2 is put in, so that the other groups can be replaced, thereby allowing the test equipment to run without stopping.

[0026] The number of guide rods 36 is a pair, one end of the guide rod 36 is provided with a receiving groove 363, a spring 364 is installed inside the receiving groove 363, one end of the spring 364 is connected to a steel ball 365, one side of the fixed plate 1 is provided with an annular groove 16, the inner wall of the annular groove 16 is in sliding contact with one end of the guide rod 36, the inner wall of the annular groove 16 is recessed inwardly and provided with a plurality of arc-shaped recesses, and the positions of the arc-shaped recesses correspond to the circumferential positions of the semicircular jacket 11 one by one, when the ball nut seat 31 rotates, it will drive the guide rod 36 to rotate around the circle, and the guide rod 36 is in the annular groove 16. The intermediate cable 33 can still be translated when switching to another angle, which is convenient for the smooth progress of the test process. When the split part 362 is retracted, the electromagnetic top block 32 can still be moved by the side plate 311 through friction when it is energized. At this time, the driving force will make the steel ball 365 break away from the arc-shaped depression, and the position of the guide rod 36 can be moved. When the electromagnetic top block 32 is not energized, the steel ball 365 will resist the arc-shaped depression, and the position of the guide rod 36 will not move, which is convenient for the movement and fixation of the guide rod 36, so as to smoothly control the rotation and translation process of the intermediate cable 33.

[0027] The electromagnetic top block 32, the electric push rod 361, the energized test head 37, and the motor 35 are all electrically connected to an external power supply and a control system, and each electrical component is controlled to operate in an orderly manner through the external power supply;

[0028] An extension clamp 12 is correspondingly installed on the outer wall of the semicircular jacket 11, and an elastic expansion part 13 is arranged between the extension clamp 12 and the semicircular jacket 11. A one-way tooth 15 is installed on the inner wall of the extension clamp 12, and a one-way tooth 14 is installed on the outer wall of the middle cable 33. The one-way tooth 14 meshes with the one-way tooth 15. When no current is detected somewhere at the outlet of the cable, since both thin cables 21 may be damaged at this time, but it is not certain which one is damaged, the two elastic expansion parts 13 are first contracted inwardly. The elastic expansion part 13 can be a telescopic gas spring or an ordinary spring. When the elastic expansion part 13 contracts inwardly, the one-way tooth 14 will mesh with the one-way tooth 15. At this time, when the middle When the cable 33 moves to the left and leaves the fixed plate 1, the semicircular jacket 11 there will be pulled to the left together with the cable protective jacket 2. At this time, when the middle cable 33 is rotated, the photovoltaic cable it clamps will be slightly bent, but it will not affect the power supply. When it reaches the cable protective jacket 2 at another angle, the middle cable 33 moves parallel to the right until its other end contacts and electrically connects with the thin cable 21 at another angle, and the cable protective jacket 2 on the opposite side is squeezed and deformed. At this time, the connection mode becomes that the original cable is electrically connected to another cable. When power is turned on again, it can be accurately known whether the cable is faulty or the other cable that is not clamped is faulty, and the faulty cable can be accurately determined.
