[0021] Reference Figures 1 to 4The embodiment of the present invention provides a copper bar marking device, comprising a housing 1, and a tool assembly and a first limiting plate 3 both arranged in the housing 1; the housing 1 has a copper bar socket 11 for inserting the copper bar into the housing 1 along a first direction. The tool assembly comprises a driving mechanism 25, a first blade 21 and a second blade 22, the first blade 21 and the second blade 22 are arranged on opposite sides of the copper bar socket 11 along a second direction, the driving mechanism 25 is used to drive the first blade 21 and the second blade 22 to move toward each other along the second direction to press out knife marks on the two side surfaces of the copper bar, or the driving mechanism 25 is used to drive the first blade 21 and the second blade 22 to move away from each other along the second direction; the first limiting plate 3 is slidably connected to the housing 1 along the first direction, the first limiting plate 3 and the copper bar socket 11 are arranged at intervals along the first direction, and the interval between the first limiting plate 3 and the copper bar socket 11 is the insertion length of the copper bar; wherein, there is a non-zero angle between the first direction and the second direction.

[0022] The interval between the first limit plate 3 and the copper bar is adjusted in advance, so as to predefine the insertion distance of the copper bar, and then the copper bar is inserted into the copper bar socket 11 until the copper bar contacts the first limit plate 3. The driving mechanism 25 is started, and the driving mechanism 25 drives the first blade 21 and the second blade 22 to move toward each other, so that the first blade 21 and the second blade 22 clamp the copper bar, and the first blade 21 and the second blade 22 are driven by the driving mechanism 25 until they can leave knife marks on the surface of the copper bar, and the knife marks on the copper bar are the drawn lines. After the lines are drawn, the driving mechanism 25 drives the first blade 21 and the second blade 22 away from each other, so that the first blade 21 and the second blade 22 no longer press the copper bar, so that the staff can pull out the copper bar from the copper bar socket 11.

[0023] When the position of the first limit plate 3 is fixed, the staff only needs to insert each copper bar into the copper bar socket 11. When the copper bar abuts the first limit plate 3, the first blade 21 and the second blade 22 press a knife mark on the copper bar. Multiple copper bars of the same batch can be marked with lines by the above method, and because the first blade 21 and the second blade 22 are relatively stable, the knife marks are relatively stable and are not easily wiped off.

[0024] As an example, the tool assembly further includes a first tool holder 23 and a second tool holder 24, the first blade 21 is mounted on the first tool holder 23, and the second tool holder 24 is arranged on the second tool holder 24. The driving mechanism 25 is a finger cylinder, which is also called a pneumatic clamp finger. The first tool holder 23 is fixed to one clamp finger of the driving mechanism 25, and the second tool holder 24 is fixed to another clamp finger of the driving mechanism 25. The first tool holder 23 and the second tool holder 24 are driven by the finger cylinder to move toward each other or away from each other. The finger cylinder described in this embodiment is a parallel clamp type.

[0025] In this embodiment, the finger cylinder is directly used to drive the first tool holder 23 and the second tool holder 24 to move toward each other, thereby driving the first blade 21 on the first tool holder 23 and the second blade 22 on the second tool holder 24 to move closer to or away from each other. The finger cylinder is also called a pneumatic clamping finger, which has the characteristics of fast response and strong power, and can shorten the line drawing time and increase the depth of the knife mark.

[0026] Reference Figure 2 and Figure 3 As an example, the tool assembly is provided with two, wherein the driving mechanism 25 of one of the tool assemblies is fixed on the housing 1, and the tool assembly is the first tool assembly 201. The driving mechanism 25 of the other tool assembly is slidably connected to the housing 1 along a third direction, and the tool assembly is the second tool assembly 202. The first direction, the second direction and the third direction are perpendicular to each other. In the present embodiment, two tool assemblies are provided, and lines can be drawn at both ends of the copper bar at the same time, and since the second tool assembly 202 can slide along the third direction, it can adapt to copper bars of different lengths or widths. And lines can also be drawn at different positions along the third direction on the same copper bar. Reference Figure 2 and Figure 3 As an example, the driving mechanism 25 of the second tool assembly 202 is slidably connected to the shell 1 through a second slide 31, the first slide 26 is fixed in the shell 1, the first position sensor 27 is arranged at one end of the length of the first slide 26, and the second position sensor 28 is arranged at the other end of the length of the first slide 26. A receiving piece 29 is arranged on the driving mechanism 25 of the second tool assembly 202. When the driving mechanism 25 of the second tool assembly 202 moves to one end of the first slide 26, the first position sensor 27 senses the receiving piece 29, and when the driving mechanism 25 of the second tool assembly 202 moves to the other end of the first slide 26, the second position sensor 28 senses the receiving piece 29.

[0027] In this embodiment, the first position sensor 27 and the second position sensor 28 are used to cooperate with the receiving piece 29 . The first position sensor 27 and the second position sensor 28 are mainly used to limit the driving mechanism 25 and define the sliding path of the driving mechanism 25 on the second slide 31 .

[0028] Reference Figure 2 and Figure 3 As an example, the copper bar marking device further includes a second limit plate 4 and a sliding assembly 41, wherein the second limit plate 4 and the first limit plate 3 are spaced apart along the third direction, the second limit plate 4 is connected to the housing 1 via the sliding assembly 41, and the sliding assembly 41 is used to drive the second limit plate 4 to slide along the first direction and along the third direction. The sliding assembly 41 in this embodiment is a cross slide, which can drive the second limit plate 4 to move along the first direction and the third direction, so that the side surface of the second limit plate 4 close to the copper bar socket 11 and the side surface of the second limit plate 4 close to the copper bar socket 11 are coplanar, so that the second limit plate 4 and the first limit plate 3 can respectively abut the two ends of the copper bar to improve the accuracy of the marking.

[0029] As an example, the first limit plate 3 is slidably connected to the housing 1 through the second slide 31, the first slide 26 is fixed on the housing 1, the first limit plate 3 is installed on the second slide 31, a receiving plate 34 is provided on the first limit plate 3, and a first sensor 32 and a second sensor 33 are provided at both ends of the length of the slide. In this embodiment, the maximum length of the second slide 31 is 550 mm, when the first limit plate 3 slides to one end of the second slide 31, the first sensor 32 senses the receiving plate 34, and when the first limit plate 3 slides to the other end of the second slide 31, the second sensor 33 senses the receiving plate 34.

[0030] The first sensor 32 and the second sensor 33 sense whether the first limit plate 3 slides to the end of the length direction of the second slide 31. The first sensor 32 and the second sensor 33 serve as soft limits for the position of the first limit plate 3 to define the two ends of the sliding path of the first limit plate 3.

[0031] Reference Figure 1 As an example, the shell 1 includes a shell body 12, connecting bolts and two hand guards 13, the shell body 12 is provided with a feed port, the two hand guards 13 are spaced apart along the second direction, the space between the two hand guards 13 is connected to the feed port, and the space between the two hand guards 13 constitutes the copper busbar socket 11.

[0032] The hand-blocking plates 13 in this embodiment are made of PVC material, and the space between the two hand-blocking plates 13 constitutes a copper bar insertion port for inserting the copper bar.

[0033] As an example, the hand guard 13 is provided with an adjustment slot 14 penetrating along the thickness direction thereof, the adjustment slot 14 extends along the second direction, and the connecting bolt penetrates the adjustment slot 14 and is threadedly connected to the shell body 12. In actual use, the connecting bolt is first loosened, and the hand guard 13 can be adjusted up and down along the second direction, thereby adjusting the width of the copper bar socket 11 along the second direction, so as to adapt to copper bars of different thicknesses.

[0034] Reference Figure 1 and Figure 4 As an example, the copper bar marking device also includes a horizontal plate 6 disposed outside the housing 1, and the horizontal plate 6 is slidably connected to the housing 1 along the second direction, and the horizontal plate 6 is used to support the copper bar at the copper bar socket 11. In this embodiment, the horizontal plate 6 is disposed outside the housing 1, and slides up and down in contact with the outer wall of the housing 1. After adjusting the copper bar socket 11 in the above manner, the position of the horizontal plate 6 can be adjusted so that the horizontal plate 6 and the bottom surface of the copper bar are parallel, thereby allowing the copper bar to be inserted into the copper bar socket 11 as horizontally as possible. Since the width of the copper bar socket 11 along the second direction must be greater than or equal to the thickness of the copper bar before the copper bar can be inserted, generally, the width of the copper bar socket 11 along the second direction is greater than the thickness of the copper bar, so the horizontal plate 6 is adjusted to a suitable position so that the copper bar is inserted into the copper bar socket 11 and can abut against the first limit plate 3 in a horizontal state, making the marking more accurate.

[0035] In this embodiment, both ends of the horizontal plate 6 are connected to cylinders respectively, and the cylinders drive the horizontal plate 6 to reciprocate along the second direction.

[0036] Reference Figure 1 As an example, the copper bar marking device further includes a foot pedal 5, the foot pedal 5 is electrically connected to the driving mechanism 25, and the foot pedal 5 is used to start or shut down the driving mechanism 25. The foot pedal 5 controls the action of the cylinder, which is a common method in the mechanical field, so it will not be described in detail.

[0037] In this embodiment, the copper busbar marking device also includes a visual detection mechanism, which includes a camera and a control device. The camera takes a picture of the copper busbar after the line is drawn, and the control device analyzes the picture taken by the camera to determine whether a line is drawn on the copper busbar, and then determines the effect of the line drawing.
