[0035] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0036] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0037] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0038] Next, the backlight detection device 100 according to the embodiments of the present invention will be specifically described with reference to the accompanying drawings.

[0039] As Figures 1 to 4 shown, the backlight detection device 100 according to the embodiments of the present invention includes: a fixed frame 10, a movable seat 20, a light source assembly 30, and a vision detection assembly 40.

[0040] Specifically, the movable seat 20 is disposed on the fixed frame 10, and the position of the movable seat 20 in the first direction is adjustable. The light source assembly 30 is disposed on the movable seat 20, and the vision detection assembly 40 is disposed on the movable seat 20. The vision detection assembly 40 and the light source assembly 30 are spaced apart in the second direction to form a detection channel suitable for the passing of the sheet material therebetween. Wherein, the light source assembly 30 is adapted to emit light towards the detection channel, and the vision detection assembly 40 is adapted to capture an image of the sheet material in the detection channel.

[0041] In other words, as Figures 1 to 4 shown, the backlight detection device 100 according to the embodiments of the present invention mainly includes a fixed frame 10, a movable seat 20, a light source assembly 30, and a vision detection assembly 40. Among them, the fixed frame 10 is used to connect to the to-be-installed position. The movable seat 20 can be installed on one side of the fixed frame 10. Both the light source assembly 30 and the vision detection assembly 40 can be installed on the side of the movable seat 20 away from the fixed frame 10. And the light source assembly 30 and the vision detection assembly 40 are spaced apart in the second direction (for example, the vertical direction), so that the space between the light source assembly 30 and the vision detection assembly 40 can be used as a detection channel. During use, the sheet material (for example, the pole piece) can pass through the detection channel. During detection, the pole piece is stationary. The light source assembly 30 emits light towards the detection channel on the first side (for example, the lower side) of the detection channel, so as to form a more obvious contour of the pole piece on the upper side of the detection channel. The vision detection assembly 40 can capture an image of the pole piece in the detection channel on the second side (for example, the upper side) of the detection channel. In this way, the position of the V-angle of the pole piece can be captured, so as to provide data reference for subsequent pole piece processing procedures and ensure the accuracy and efficiency of the processing process.

[0042] In this embodiment, the position of the movable seat 20 on the fixed frame 10 is adjustable in the first direction. The ways to realize the position adjustment of the movable seat 20 include but are not limited to the following situations:

[0043] Situation 1: The movable seat 20 is movably disposed on the fixed frame 10 in the first direction and is driven to move in the first direction by a driving structure;

[0044] Situation 2: The movable seat 20 is movably disposed on the fixed frame 10 in the first direction. After manually adjusting the position of the movable seat 20, the position of the movable seat 20 is locked by a locking structure;

[0045] When the position of the V-angle of the pole piece changes in the first direction, by adjusting the position of the movable seat 20 in the first direction, the positions of the light source assembly 30 and the vision detection assembly 40 in the first direction can be changed together, so that the light source assembly 30 and the vision detection assembly 40 can be adjusted to the corresponding positions.

[0046] Thus, for the backlight detection device 100 according to the embodiment of the present invention, by arranging the light source assembly 30 and the vision detection assembly 40 on the movable seat 20 whose position can be adjusted in the first direction, when the position of the V-angle of the pole piece changes in the first direction, only by adjusting the position of the movable seat 20 can the positions of the light source assembly 30 and the vision detection assembly 40 be quickly changed, so that the backlight detection device 100 can quickly adapt to the detection requirements of different types of pole pieces, realize quick model changeover, and further ensure the production efficiency of the pole pieces.

[0047] In some embodiments of the present invention, the movable seat 20 is movably arranged on the fixed frame 10 along the first direction, and the backlight detection device 100 further includes: a driving assembly 50, the driving assembly 50 is arranged on the fixed frame 10, and the driving assembly 50 is connected to the movable seat 20 to drive the movable seat 20 to move along the first direction.

[0048] Specifically, as Figures 1 to 3 shown, a first slide rail 11 is fixedly connected to one side of the fixed frame 10, the first slide rail 11 extends along the first direction, the movable seat 20 is fixedly connected with a first slider 21, and the first slider 21 is slidably installed on the first slide rail 11 along the first direction, so that the movable seat 20 can move relative to the fixed frame 10 along the first direction, and the light source assembly 30 and the vision detection assembly 40 can also move along the first direction with the movable seat 20.

[0049] As Figures 1 to 3 shown, a driving assembly 50 is arranged on the fixed frame 10, and the output end of the driving assembly 50 is connected to the movable seat 20, so that the driving assembly 50 can drive the movable seat 20 to move along the first direction, which is beneficial to accurately adjust the light source assembly 30 and the vision detection assembly 40 to the position directly opposite to the V-angle of the pole piece, so that when the position of the V-angle of the pole piece changes in the first direction, the backlight detection device 100 can quickly make corresponding adjustments and realize quick model changeover.

[0050] According to an embodiment of the present utility model, the driving assembly 50 includes a lead screw 51, a driving slider 52 and a motor 53. The lead screw 51 extends along a first direction and is rotatably disposed on the fixing frame 10 about its own axis. The driving slider 52 is threadedly connected to the lead screw 51 and is connected to the movable seat 20 to drive the movable seat 20 to move. The motor 53 is disposed on the fixing frame 10, and the output end of the motor 53 is connected to one end of the lead screw 51 to drive the lead screw 51 to rotate.

[0051] That is to say, as Figures 1 to 3 shown, the driving assembly 50 mainly includes a lead screw 51, a driving slider 52 and a motor 53. During installation, the axial direction of the lead screw 51 is kept consistent with the first direction. Both ends of the lead screw 51 are rotatably mounted on the fixing frame 10 about its own axis. The driving slider 52 is sleeved on the lead screw 51 and is threadedly connected thereto. The driving slider 52 is movably mounted on the fixing frame 10 along the first direction, and the driving slider 52 is fixedly connected to the movable seat 20. In this way, when the lead screw 51 rotates, the movable seat 20 can be driven to move along the first direction by the driving slider 52.

[0052] The motor 53 can be a servo motor 53. The motor 53 is fixedly mounted on the fixing frame 10, and the conveying end of the motor 53 is fixedly connected to one end of the lead screw 51. By the driving force of the motor 53, the lead screw 51 can be rotated, so as to drive the driving slider 52 to move along the first direction. Since the driving slider 52 is fixedly connected to the movable seat 20, when the driving slider 52 moves, the movable seat 20 will also move correspondingly along the first direction. Thus, the adjustment of the position of the movable seat 20 can be realized.

[0053] In this embodiment, through the cooperation of the motor 53, the lead screw 51 and the driving slider 52, the position of the movable seat 20 in the first direction can be accurately adjusted, which is beneficial to accurately adjust the light source assembly 30 and the vision detection assembly 40 to the position directly facing the V-angle of the pole piece.

[0054] In some embodiments of the present utility model, the light source assembly 30 includes a first connecting seat 31 and a light source 32. The first connecting seat 31 is disposed on the movable seat 20, and the position of the first connecting seat 31 in a second direction is adjustable. The light source 32 is disposed on the first connecting seat 31, and the light source 32 is adapted to emit light to the detection channel.

[0055] Specifically, as Figures 1 to 3As shown, the light source assembly 30 mainly includes a first connecting seat 31 and a light source 32. The first connecting seat 31 is mounted on the movable seat 20, and the position of the first connecting seat 31 in the second direction on the movable seat 20 is adjustable. For example, the first connecting seat 31 is movably connected to the movable seat 20 along the second direction, and a driving member can be used to drive the first connecting seat 31 to move in the second direction, thereby realizing the position adjustment of the first connecting seat 31 in the second direction.

[0056] The light-emitting surface of the light source 32 faces the detection channel, so that the light source 32 can emit light to the detection channel, and the brightness of the light source 32 is adjustable, so that the brightness of the light source 32 can be adjusted according to actual needs. The light source 32 can be fixedly mounted on the first connecting seat 31, and by adjusting the position of the first connecting seat 31 in the second direction, the position adjustment of the light source 32 can be realized, so as to adapt to the change of the width of the pole piece.

[0057] Thus, when the width of the pole piece changes, by adjusting the position of the light source 32 in the second direction, the distance between the light source 32 and the pole piece can be effectively adjusted, and it can be ensured that the position and brightness of the light source 32 are properly corresponding to the width of the pole piece, which can effectively improve the flexibility and adaptability of the use of the light source 32.

[0058] According to an embodiment of the present invention, the first connecting seat 31 is provided with a first long hole 311, the length direction of the first long hole 311 is the second direction, and the backlight detection device 100 further includes: a first locking member, one end of the first locking member passes through the first long hole 311 and is connected to the movable seat 20, and the first locking member is adapted to lock or release the first connecting seat 31, so that the position of the first connecting seat 31 in the second direction is adjustable.

[0059] That is to say, as Figures 1 to 3 shown, the backlight detection device 100 further includes a plurality of first locking members. The first locking member can be a screw. The first connecting seat 31 is provided with a plurality of first long holes 311 penetrating along the third direction. The length direction of the first long holes 311 is the same as the second direction, and the width of the first long holes 311 is the same as the radial dimension of the first locking member. The first end of the first locking member can pass through the first long hole 311 and be threadedly connected to the movable seat 20. When the first locking member is tightened, the second end of the first locking member locks the first connecting seat 31 on the movable seat 20; when the first locking member is not tightened (i.e., loosened), the second end of the first locking member releases the first connecting seat 31, so that the first connecting seat 31 is movable in the second direction.

[0060] Thus, when adjusting the position of the first connecting seat 31, only need to loosen the first locking member, and the first connecting seat 31 can move along the second direction. After adjusting to the appropriate position, tighten the first locking member again, and the first connecting seat 31 can be firmly locked on the movable seat 20.

[0061] In this embodiment, the first locking member is provided to lock or release the first connecting seat 31, with a simple structure and convenient adjustment of the position of the first connecting seat 31.

[0062] In some embodiments of the present utility model, the vision detection assembly 40 includes: a second connecting seat 41 and a detection camera 42. The second connecting seat 41 is provided on the movable seat 20, and the position of the second connecting seat 41 in the second direction is adjustable. The detection camera 42 is provided on the second connecting seat 41, and the detection camera 42 is adapted to capture an image of the sheet material in the detection channel.

[0063] In other words, as Figures 1 to 3 shown, the vision detection assembly 40 according to the embodiment of the present utility model mainly includes a second connecting seat 41 and a detection camera 42. The second connecting seat 41 is installed on the movable seat 20, and the position of the second connecting seat 41 in the second direction on the movable seat 20 is adjustable. For example, the second connecting seat 41 is movably connected to the movable seat 20 in the second direction, and a driving member can drive the first connecting seat 31 to move in the second direction, thereby realizing the adjustment of the position of the first connecting seat 31 in the second direction.

[0064] The detection camera 42 can be a CCD camera with adjustable focal length. The detection camera 42 can capture an image of the sheet material in the detection channel. The detection camera 42 can be fixedly installed on the second connecting seat 41, and the adjustment of the detection camera 42 can be realized by adjusting the position of the second connecting seat 41 in the second direction, thereby adapting to the change of the width of the pole piece.

[0065] Thus, when the width of the pole piece changes, by adjusting the position of the detection camera 42 in the second direction, the distance between the detection camera 42 and the pole piece can be effectively adjusted, ensuring that the focal length and shooting area of the detection camera 42 can match the width of the pole piece, thereby ensuring that the detection camera 42 can adapt to the shooting requirements of pole pieces with different widths and improving the flexibility and accuracy of detection.

[0066] According to an embodiment of the present utility model, the second connecting seat 41 is provided with a second long hole 411. The length direction of the second long hole 411 is the second direction. The backlight detection device 100 further includes: a second locking member 412. One end of the second locking member 412 passes through the second long hole 411 and is connected to the movable seat 20. The second locking member 412 is adapted to lock or release the second connecting seat 41, so that the position of the second connecting seat 41 in the second direction is adjustable.

[0067] That is to say, as Figures 1 to 3As shown, the backlight detection device 100 further includes a plurality of second locking members 412. The second locking members 412 can be screws. The second connection base 41 is provided with a plurality of second long holes 411 penetrating along the third direction. The length direction of the second long holes 411 is the same as the second direction. The width of the second long holes 411 is the same as the radial dimension of the second locking members 412. The first end of the second locking members 412 can pass through the second long holes 411 and be threadedly connected to the movable seat 20. When the second locking members 412 are tightened, the second ends of the second locking members 412 lock the second connection base 41 to the movable seat 20. When the second locking members 412 are not tightened (i.e., loosened), the second ends of the second locking members 412 release the second connection base 41, enabling the second connection base 41 to be movable in the second direction.

[0068] Thus, when adjusting the position of the second connection base 41, only need to loosen the second locking members 412, and the second connection base 41 can move along the second direction. After adjusting to a suitable position, tighten the second locking members 412 again, and the second connection base 41 can be firmly locked to the movable seat 20.

[0069] In this embodiment, by providing the second locking members 412, the second connection base 41 can be locked or released, with a simple structure and convenient for adjusting the position of the second connection base 41.

[0070] In some embodiments of the present utility model, the backlight detection device 100 further includes: a light-transmitting component 60. The light-transmitting component 60 is provided on the movable seat 20. The light-transmitting component 60 is located between the visual detection component 40 and the light source component 30. The light-transmitting component 60 is provided with two light-transmitting parts spaced apart along the second direction. A detection channel is defined between the two light-transmitting parts. The two light-transmitting parts cooperate to smooth the sheet material.

[0071] Specifically, as Figures 1 to 3 shown, the visual detection component 40 and the light source component 30 are provided with the light-transmitting component 60. The light-transmitting component 60 is installed on the movable seat 20. The light-transmitting component 60 has two light-transmitting parts, which are spaced apart along the second direction, so that a detection channel is defined between the two light-transmitting parts. And the dimension of the detection channel in the first direction, that is, the dimension between the two light-transmitting parts, is slightly larger than the thickness of the pole piece, so that the pole piece can be smoothed by the two light-transmitting parts when extending into the detection channel, which can ensure the accuracy of subsequent detection.

[0072] In this embodiment, the light-transmitting component 60 can move together with the movable seat 20. When the position of the V-angle of the pole piece in the first direction changes, by adjusting the position of the movable seat 20 in the first direction, the positions of the light source component 30, the visual detection component 40 and the light-transmitting component 60 in the first direction can be changed together, so that the backlight detection device 100 can quickly adapt to the detection requirements of different models of pole pieces and realize rapid model change.

[0073] According to an embodiment of the present utility model, the position of the light-transmitting component 60 in the second direction and / or the third direction is adjustable.

[0074] That is to say, on the movable seat 20, the position of the light-transmitting component 60 in the second direction is adjustable. For example, the light-transmitting component 60 is movably arranged on the movable seat 20 along the second direction, and a driving member can drive the light-transmitting component 60 to move in the second direction, so as to realize the position adjustment of the light-transmitting component 60 in the second direction, which is beneficial to adjusting the light-transmitting component 60 to a height adapted to the loading position of the pole piece.

[0075] Optionally, on the movable seat 20, the position of the light-transmitting component 60 in the third direction is also adjustable. For example, the light-transmitting component 60 is movably arranged on the movable seat 20 along the third direction, and a driving member can drive the light-transmitting component 60 to move in the third direction, so as to realize the position adjustment of the light-transmitting component 60 in the third direction, which is beneficial to adjusting the light-transmitting component 60 to a position adapted to the pole piece.

[0076] Furthermore, on the movable seat 20, the positions of the light-transmitting component 60 in the second direction and the third direction are both adjustable.

[0077] Thus, by adjusting the position of the light-transmitting component 60, the position of the detection channel can be changed, so that the backlight detection device 100 can quickly adapt to different working conditions.

[0078] In some embodiments of the present utility model, the backlight detection device 100 further includes: a third connecting seat 70, a third locking member and a fourth locking member. The third connecting seat 70 is provided with a third long hole 71, the length direction of the third long hole 71 is the second direction, the light-transmitting component 60 is movably arranged on the third connecting seat 70 along the third direction, one end of the third locking member passes through the third long hole 71 and is connected to the movable seat 20, the third locking member is adapted to lock or release the third connecting seat 70, so that the position of the third connecting seat 70 in the second direction is adjustable, and the fourth locking member is arranged on the third connecting seat 70 or the light-transmitting component 60, and the fourth locking member is adapted to lock or release the light-transmitting component 60, so that the position of the light-transmitting component 60 in the third direction is adjustable.

[0079] Specifically, as Figures 1 to 3As shown, the backlight detection device 100 further includes a third connector 70, a third locking member, and a fourth locking member. Among them, the light-transmitting component 60 is installed on the third connector 70. The third connector 70 is provided with a plurality of third long holes 71 penetrating along the third direction. The length direction of the third long holes 71 is the same as the second direction. The width of the third long holes 71 is the same as the radial dimension of the third locking member. The first end of the third locking member can pass through the third long holes 71 and be threadedly connected to the movable seat 20. When the third locking member is tightened, the second end of the third locking member locks the third connector 70 on the movable seat 20; when the third locking member is not tightened (i.e., loosened), the second end of the third locking member releases the third connector 70, so that the third connector 70 is movable in the second direction.

[0080] Thus, when adjusting the position of the third connector 70, only need to loosen the third locking member, and the third connector 70 can move along the second direction. After adjusting to the appropriate position, then tighten the third locking member, and the first connector 31 can be firmly locked on the movable seat 20, so as to realize the adjustment of the position of the light-transmitting component 60 in the second direction.

[0081] Furthermore, the third connector 70 is provided with a second sliding rail extending along the third direction, and the light-transmitting component 60 is provided with a second sliding block. The second sliding block is slidably installed on the second sliding rail along the third direction, so that the light-transmitting component 60 can be movable relative to the third connector 70 along the third direction, and thus the position can be adjusted by moving the light-transmitting component 60 in the third direction.

[0082] As Figures 1 to 3 shown, the fourth locking member can be arranged on the third connector 70 or the light-transmitting component 60. For example, the fourth locking member can be a screw, and the fourth locking member is threadedly connected to the second sliding rail. When the fourth locking member is tightened, the fourth locking member abuts against the third connector 70, so as to lock the light-transmitting component 60 on the third connector 70, thereby avoiding unnecessary slippage of the light-transmitting component 60; when the fourth locking member is loosened, the fourth locking member cancels the abutment against the third connector 70, and the light-transmitting component 60 is movable along the third direction, and the light-transmitting component 60 can be moved during adjustment.

[0083] According to an embodiment of the present invention, the light-transmitting component 60 includes: a connecting member 61, a first light-transmitting plate 62, and a second light-transmitting plate 63.

The first end of the second guiding portion 65 is arranged on the first light-transmitting plate 62. In the second direction, the distance between the second guiding portion 65 and the first light-transmitting plate 62 gradually increases from the first end to the second end of the second guiding portion 65.

[0087] That is to say, as Figures 1 to 4 shown, the first light-transmitting plate 62 is provided with a first guiding portion 64 at the first end in the first direction. The first guiding portion 64 can be an arc-shaped plate. The first end of the first guiding portion 64 can be fixedly connected to the first end of the first light-transmitting plate 62. The second end of the first guiding portion 64 is far from the first light-transmitting plate 62. And in the second direction, the distance between the first guiding portion 64 and the second light-transmitting plate 63 gradually increases from the first end to the second end of the first guiding portion 64. When the pole piece extends into the detection channel, the pole piece far from the second light-transmitting plate 63 can be guided into the detection channel through the first guiding portion 64, so that the pole piece can be prevented from being damaged when entering the detection channel.

[0088] As Figure 4 shown, the second light-transmitting plate 63 is provided with a second guiding portion 65 at the first end in the first direction. The second guiding portion 65 can be an arc-shaped plate. The first end of the second guiding portion 65 can be fixedly connected to the first end of the second light-transmitting plate 63. The second end of the second guiding portion 65 is far from the second light-transmitting plate 63. And in the second direction, the distance between the second guiding portion 65 and the first light-transmitting plate 62 gradually increases from the first end to the second end of the second guiding portion 65. When the pole piece extends into the detection channel, the pole piece far from the first light-transmitting plate 62 can be guided into the detection channel through the second guiding portion 65, so that the pole piece can be prevented from being damaged when entering the detection channel.
