[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] The defect of the copper busbar integrated production line in the prior art is that when the copper busbar needs to be bent in a Z-shape, it is often necessary to bend it manually or by using a special bending machine, and it is not possible to automatically bend the copper busbar in a Z-shape, which is very inconvenient.

[0040] To solve the above problems, the main concept adopted in this embodiment is: the fixed plate drives the movable plate to move, and the copper bar on the movable plate cooperates with the fixed plate to achieve Z-shaped bending of the copper bar as the movable plate moves.

[0041] In order to better understand the above technical solution, Figure 1-6 And specific implementation methods are used to describe the above technical solutions in detail:

[0042] The present invention provides an integrated copper busbar production line, including a copper busbar automatic production line, wherein the copper busbar automatic production line includes a bending mechanism, a cutting knife is arranged in front of the bending mechanism, and the bending mechanism includes:

[0043] A movable plate 1, wherein the movable plate 1 is used to bend the copper busbar;

[0044] A fixed plate 2, the fixed plate 2 is located on one side of the moving plate 1, and cooperates with the moving plate 1 to make the moving plate 1 move;

[0045] The two connecting rods 3 are located between the movable plate 1 and the fixed plate 2. The front and rear ends of the two connecting rods 3 are respectively matched with the movable plate 1 and the fixed plate 2, so that the movable plate 1 can bend the copper busbar.

[0046] When the copper bar has been processed through the previous process and needs to be bent in a Z shape and enter the bending mechanism, the copper bar is on the surface of the movable plate 1 at this time, and the movable plate 1 begins to translate with the cooperation of the fixed plate 2. Since the connecting rod 3 is located between the movable plate 1 and the fixed plate 2, the movable plate 1 can perform a Z-shape bend on the copper bar with the cooperation of the connecting rod 3, so that the copper bar can be bent while being fed. Compared with the prior art, which requires the copper bar to be cut off before being sent into the bending machine, this solves the problem of discontinuous work flow and low work efficiency.

[0047] As an embodiment of the present invention, a sliding groove is provided on the surface of the movable plate 1, the upper end of the connecting rod 3 is located in the sliding groove and exceeds the surface of the movable plate 1, and the movable plate 1 further includes:

[0048] A limiting column 11, the lower surface of which is rotatably connected to the surface of the moving plate 1, and two limiting columns 11 are arranged in a staggered manner to limit the copper bar;

[0049] The slider 12 is located at a position corresponding to the slide slot 23 and is fixedly connected to the outer surface of the connecting rod 3 that extends beyond the surface of the movable plate 1. The lower surface of the slider 12 is slidably connected to the surface of the movable plate 1.

[0050] A pressure head 13, which is fixedly connected to one end of the slider 12 close to the limit column 11 and is slidably connected to the surface of the movable plate 1, and is used for bending the copper busbar;

[0051] A rack 14, wherein the rack 14 is fixedly connected to the central position of the back side of the movable plate 1, and the axis direction of the rack 14 is perpendicular to the axis direction of the slider 12;

[0052] A groove is provided at the central position of the fixed plate 2, and the fixed plate 2 further comprises:

[0053] A transmission shaft 21, one end of which is fixedly connected to a motor, and the other end of which passes through the fixed plate 2 and is rotatably connected to the fixed plate 2, and the axial direction of the transmission shaft 21 is perpendicular to the axial direction of the rack 14;

[0054] The gear 22 is located in the groove, the inner surface of the gear 22 is fixedly connected to the outer surface of the transmission shaft 21, and the gear 22 is meshed with the rack 14 to drive the moving plate 1 to move;

[0055] The two groups of slide grooves 23 are arranged on one side of the fixed plate 2 close to the rack 14 , and are distributed above and below the gear 22 , and the lower ends of the two connecting rods 3 slide in the slide grooves 23 .

[0056] When the copper bar enters the bending mechanism, the copper bar passes between the two misaligned limiting posts 11, so that the limiting posts 11 limit the copper bar. As the copper bar is fed to a suitable position, that is, when the pressure head 13 matched with the connecting rod 3 above the gear 22 can squeeze the copper bar, the motor is started at this time, and the motor starts to work to drive the transmission shaft 21 to rotate, so that the gear 22 in the groove starts to rotate. Since the gear 22 is meshed with the rack 14, the rack 14 starts to move along the rotation direction of the gear 22, thereby causing the movable plate 1 to move along the moving direction of the rack.

[0057] As the movable plate 1 moves along the moving direction of the rack 14, the lower end of the connecting rod 3 slides in the slide groove 23, and the upper end of the connecting rod 3 exceeds the outer surface of the movable plate 1 and is fixedly connected to the slider 12;

[0058] The upper connecting rod 3 starts to slide along the front end of the sliding groove 23 above the gear 22, and the slider 12 slides horizontally on the surface of the movable plate 1 and also slides longitudinally downward along the sliding groove. The lower connecting rod 3 slides along the front end of the sliding groove 23 below the gear 22, and the slider 12 connected to the lower connecting rod 3 only slides horizontally along the surface of the movable plate 1;

[0059] The upper connecting rod 3 starts to slide along the rear end of the slide groove 23 above the gear 22, and the slider 12 only slides horizontally on the surface of the movable plate 1. The lower connecting rod 3 slides along the rear end of the slide groove 23 below the gear 22. The slider 12 connected to the lower connecting rod 3 slides horizontally along the surface of the movable plate 1 and also slides vertically upward along the lower slide groove.

[0060] Since the pressure head 13 is fixedly connected to one end of the limiting column 11 of the slider 12, the pressure head 13 slides synchronously with the slider 12, thereby achieving Z-shaped bending of the copper busbar;

[0061] Since the copper bar passes through the limit columns 11 and is slidably connected to the limit columns 11, when the movable plate 1 moves, under the action of friction, the pressure head 13 will drive the copper bar to make a feeding motion, thereby realizing the automated production of the Z-shaped bending of the copper bar, which is easy to operate and has a simple structure.

[0062] As an implementation mode of the present invention, a return groove 24 is further provided on the fixed plate 2 , and the return groove 24 is connected to the slide groove 23 above the gear 22 .

[0063] When a section of copper bar is bent, the movable plate 1 needs to be reset, and the motor reverses at this time. In order to prevent the slider 12 and the pressure head 13 corresponding to the slide groove 23 above the gear 22 from affecting the subsequent copper bar during the return process, that is, the pressure head 13 will squeeze the subsequent copper bar during the return process, so that the subsequent copper bar is squeezed and affected in bending, a return groove 24 is opened on the fixed plate 2, and is connected to the slide groove 23 above the gear 22, so that the movable plate 1 can slide along the return groove 24 through the connecting rod 3 and reset, thereby avoiding the pressure head 13 from squeezing the subsequent copper bar when returning along the slide groove 23.

[0064] As an implementation mode of the present invention, a baffle 25 is hingedly connected to the left end of the return groove 24 and the slide groove 23 above the gear 22 through a spring, and the baffle 25 can only be flipped upward.

[0065] In order to ensure that the movable plate 1 can be reset by sliding the connecting rod 3 along the return groove 24 instead of reset along the slide groove 23, a baffle 25 is hinged at the left end of the connection between the return groove 24 and the slide groove 23 above the gear 22. As the connecting rod 3 slides along the slide groove 23 and enters the return groove 24, the baffle 25 will be knocked open. Since the baffle 25 can only be flipped upward, when the motor is reversed, the connecting rod 3 cannot be reset along the slide groove 23, so that the connecting rod 3 can only slide along the return groove 24, so that the movable plate 1 can be reset by sliding the connecting rod 3 along the return groove 24 when it is reset.

[0066] As an embodiment of the present invention, the fixed plate 2 is further provided with a cutting groove 26, which is connected to the end of the slide groove 23 below the gear 22. A sensor is provided at the end of the cutting groove 26, and the sensor is electrically connected to the cutting knife in front of the bending mechanism.

[0067] When the connecting rod 3 in the slide groove 23 below the gear 22 enters the cutting groove 26 along the slide groove 23 and slides to the end of the cutting groove 26, the sensor at the end of the cutting groove 26 is sensed, thereby driving the cutting knife in front of the bending mechanism to move and cut the copper bar. At this time, the connecting rod 3 in the slide groove 23 above the gear 22 is in the stage of entering from the slide groove 23 to the return groove 24.

[0068] As an implementation manner of the present invention, the motor is a low-speed high-torque motor.

[0069] By setting the motor to be a low-speed high-torque motor, the gear 22 rotates slowly, thereby slowly driving the moving plate 1 to move, so as to ensure the bending effect of the copper busbar.

[0070] As an implementation manner of the present invention, the length of the moving plate 1 exceeds the length of the fixed plate 2 .

[0071] Since the movable plate 1 moves and bends the copper bar through the engagement of the gear 22 and the rack 14, in order to prevent the movable plate 1 from being too short and causing the gear 22 and the rack 14 to fail to engage, resulting in the movable plate 1 being unable to move and thus losing the bending function, the length of the movable plate 1 is set to exceed the length of the fixed plate 2.

[0072] As an implementation mode of the present invention, the slide groove 23 and the return groove 24 have the same depth and neither of them exceeds the distance between the transmission shaft 21 and the surface of the fixed plate 2 .

[0073] In order to prevent the depth of the slide groove 23 and the return groove 24 from exceeding the distance between the transmission shaft 21 and the surface of the fixed plate 2, causing the connecting rod 3 to interfere with the transmission shaft 21, affecting the rotation of the transmission shaft 21, and causing the movable plate 1 to be unable to move, and also to avoid the height difference when the connecting rod 3 enters the return groove 24 from the slide groove 23, the depths of the slide groove 23 and the return groove 24 are the same and neither exceeds the distance between the transmission shaft 21 and the surface of the fixed plate 2.

[0074] As an implementation mode of the present invention, the movable plate 1 and the fixed plate 2 are placed vertically.

[0075] By placing the movable plate 1 and the fixed plate 2 vertically, space is saved and the problem of the copper bar exceeding the movable plate 1 shaking in the horizontal direction, thereby preventing the safety hazard, is avoided, thereby improving safety.

[0076] Working principle: When the copper bar enters the bending mechanism, it passes between the two misaligned limit posts 11, so that the limit posts 11 limit the copper bar. As the copper bar is fed to a suitable position, that is, when the pressure head 13 cooperating with the connecting rod 3 above the gear 22 can squeeze the copper bar, the motor is started at this time, and the motor starts to work to drive the transmission shaft 21 to rotate, so that the gear 22 in the groove starts to rotate. Since the gear 22 is meshed with the rack 14, the rack 14 starts to move along the rotation direction of the gear 22, thereby causing the movable plate 1 to move along the moving direction of the rack.

[0077] As the movable plate 1 moves along the moving direction of the rack 14, the lower end of the connecting rod 3 slides in the slide groove 23, and the upper end of the connecting rod 3 exceeds the outer surface of the movable plate 1 and is fixedly connected to the slider 12;

[0078] The upper connecting rod 3 starts to slide along the front end of the sliding groove 23 above the gear 22, and the slider 12 slides horizontally on the surface of the movable plate 1 and also slides longitudinally downward along the sliding groove. The lower connecting rod 3 slides along the front end of the sliding groove 23 below the gear 22, and the slider 12 connected to the lower connecting rod 3 only slides horizontally along the surface of the movable plate 1;

[0079] The upper connecting rod 3 starts to slide along the rear end of the slide groove 23 above the gear 22, and the slider 12 only slides horizontally on the surface of the movable plate 1. The lower connecting rod 3 slides along the rear end of the slide groove 23 below the gear 22. The slider 12 connected to the lower connecting rod 3 slides horizontally along the surface of the movable plate 1 and also slides vertically upward along the lower slide groove.

[0080] Since the pressure head 13 is fixedly connected to one end of the limiting column 11 of the slider 12, the pressure head 13 slides synchronously with the slider 12, thereby achieving Z-shaped bending of the copper busbar;

[0081] Since the copper bar passes through the limiting pillars 11 and is slidably connected with the limiting pillars 11, when the movable plate 1 moves, the pressure head 13 drives the copper bar to make a feeding motion under the action of friction, thereby realizing the automatic production of Z-shaped bending of the copper bar, which is easy to operate and has a simple structure.

[0082] When a section of copper bar is bent, the movable plate 1 needs to be reset, and the motor reverses at this time. In order to prevent the slider 12 and the pressure head 13 corresponding to the slide groove 23 above the gear 22 from affecting the subsequent copper bar during the return process, that is, the pressure head 13 will squeeze the subsequent copper bar during the return process, so that the subsequent copper bar is squeezed and affected in bending, a return groove 24 is opened on the fixed plate 2, and is connected to the slide groove 23 above the gear 22, so that the movable plate 1 can slide along the return groove 24 through the connecting rod 3 and reset, thereby avoiding the pressure head 13 from squeezing the subsequent copper bar when returning along the slide groove 23.

[0083] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as the combination of these technical features does not exist, the above-mentioned embodiments only express several implementation methods of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, several modifications and improvements can be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
