Description

Technical Field

[0001] This invention relates to an apparatus for producing steel plates for weighing scales, and more particularly to an intelligent flipping device for steel plates in weighing scales. Background Technology

[0002] The core principle of current weighing scales is to convert a person's weight into an electrical signal using sensors. The core component is typically a steel strain gauge. When a person stands on the scale, gravity is transmitted to the steel strain gauge through a mechanical structure, causing the steel plate to deform. The strain gauge attached to the steel plate also experiences micro-strain, resulting in a slight change in its resistance. By using multiple steel strain gauges to form a Wheatstone bridge circuit, this minute resistance change is converted into a differential voltage signal. After amplification and analog-to-digital conversion, the processor can calculate the weight.

[0003] Steel sheet strain sensors typically use a stamped steel sheet as the main body. Due to defects in the stamping process, the dimensions of the front and back of the steel sheet often differ. If the strain gauges are not uniformly attached to the front or back, inconsistencies in the steel sheet strain sensor's design will lead to errors in the final measurement results. To address this, current production processes often involve creating a notch on one side of the steel sheet, followed by a process on the production line using a diffuse reflection photoelectric sensor to determine the front and back of the steel sheet for selection. However, the steel sheet often undergoes surface electroplating during production, which can cause the diffuse reflection photoelectric sensor to misjudge the orientation.

[0004] Therefore, overcoming the aforementioned defects and standardizing the orientation of the front and back of steel sheets on the production line has become an important issue that urgently needs to be addressed by those skilled in the art. Summary of the Invention

[0005] This invention overcomes the shortcomings of the above-mentioned technologies and provides an intelligent flipping device for the steel plates of a weighing scale.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart steel plate flipping device for a weight scale includes a detection conveying trough 1 and a feeding conveying trough 2 connected in sequence. The detection conveying trough 1 is used to receive steel plates 3 with uncertain front and back orientations from an upstream process. The feeding conveying trough 2 is used to feed steel plates 3 with their front facing up to a downstream process. The detection conveying trough 1 is provided with a push detection component that identifies the front and back of the steel plate by pushing the side of the steel plate 3. A flipping component 4 capable of flipping the steel plate 3 is provided between the detection conveying trough 1 and the feeding conveying trough 2. The flipping component 4 flips or does not flip the steel plate 3 after passing through the flipping component 4 according to the detection result of the push detection component.

[0008] Preferably, the pressing detection assembly includes a clamping module 5 disposed above the end of the detection conveying groove 1 for applying pressure to the lower steel sheet 3. The pressing detection assembly also includes a pressing module 6 disposed on the side of the end of the detection conveying groove 1. The pressing module 6 includes a first slide 61 that can approach or move away from the detection conveying groove 1. The end of the first slide 61 near the detection conveying groove 1 is provided with an extension rod 62 that can be inserted into the detection conveying groove 1. The front end of the extension rod 62 is provided with a tip 621. The bottom surface of the tip 621 is in contact with the bottom surface of the detection conveying groove 1, and the top surface extends from the tip towards the bottom surface of the detection conveying groove 1. The first slide 61 gradually rises in the direction of the steel sheet 3 at the end of the detection conveying groove 1. When the front of the steel sheet 3 is facing down, the tip 621 can be inserted into the bottom of the steel sheet 3 along the collapsed corner area 31 of the steel sheet 3 as the first slide 61 approaches the detection conveying groove 1. When the back of the steel sheet 3 at the end of the detection conveying groove 1 is facing down, the tip 621 cannot be inserted into the bottom of the steel sheet 3. The pushing module 6 also includes a first photoelectric sensor 63 for detecting whether the first slide 61 has moved into place. When the tip 621 cannot be inserted into the bottom of the steel sheet 3, the first slide 61 cannot move into place and triggers the first photoelectric sensor 63.

[0009] Preferably, the pushing module 6 further includes a guide rail 64 extending laterally perpendicular to the end side of the detection conveying groove 1. The first slide 61 is movably connected to the guide rail 64 and moves laterally. A second slide 65, which can move laterally, is also movably connected to the guide rail 64. The first slide 61 is located between the second slide 65 and the detection conveying groove 1. A first compression spring 66 is connected between the first slide 61 and the second slide 65. A limiting movable link 67 is also connected between the first slide 61 and the second slide 65 so that the two slides can move closer or further apart within a certain range. One end of the limiting movable link 67 is fixed to the first slide 61, and the other end is movably connected to the second slide 65 and can move laterally relative to the second slide 65. The pushing module 6 further includes a first electric push rod 68 connected to the second slide 65 for driving the second slide 65 to move laterally along the guide rail 64. The first photoelectric sensor 63 is fixed to the guide rail 64.

[0010] Preferably, a second photoelectric sensor 69 is also fixed on the guide rail 64 for detecting whether the second slide 65 has moved to the designated position.

[0011] Preferably, the clamping module 5 includes a third slide 51 that is disposed above the end of the detection conveying groove 1 and can move up and down. A first clamping arm 52 extending downward is connected to the third slide 51. A first roller 53 is rotatably connected to the first clamping arm 52 so as to make rolling contact with the steel sheet 3 below. A second compression spring 54 for providing downward pressure to the third slide 51 is connected to the top of the third slide 51.

[0012] Preferably, the flipping assembly 4 includes a rotating seat 41 located at the end of the detection conveying channel 1, which is rotatable about a horizontal axis. The axis of rotation of the rotating seat 41 is perpendicular to the extension direction of the detection conveying channel 1. The rotating seat 41 is provided with a flipping groove 42 for the steel sheet 3 output from the end of the detection conveying channel 1 to enter. The flipping groove 42 is the same width as the steel sheet 3 and extends in the same direction as the extension direction of the detection conveying channel 1. The flipping groove 42 passes through the rotating seat 41. When the pushing detection assembly detects that the back side of the steel sheet 3 at the end of the detection conveying channel 1 is facing up, and the steel sheet 3 enters the flipping groove 42, the rotating seat 41 will rotate 180° to flip the steel sheet 3 to face up. When the pushing detection assembly detects that the front side of the steel sheet 3 at the end of the detection conveying channel 1 is facing up, and the steel sheet 3 enters the flipping groove 42, the rotating seat 41 will not move.

[0013] Preferably, the flipping assembly 4 further includes a second electric push rod 43. The rotating seat 41 is provided with a through hole 411 coaxially arranged with its rotation axis. The second electric push rod 43 is coaxially arranged with the rotating seat 41 and can extend through the through hole 411 to enter the flipping groove 42 and retract to exit the flipping groove 42. The flipping groove 42 also extends away from the second electric push rod 43 and penetrates the end face of the rotating seat 41 so that the second electric push rod 43 can push the steel sheet 3 in the flipping groove 42 in a direction perpendicular to the detection conveying groove 1.

[0014] Preferably, the intelligent flipping device further includes an anti-pullback component 7, which includes a fourth slide 71 that is movable up and down and is disposed above the inlet of the detection conveying trough 1. A second pressing arm 72 extending downward is connected to the fourth slide 71. A second roller 73 is rotatably connected to the second pressing arm 72 so as to make rolling contact with the steel sheet 3 below. A third compression spring 74 for providing downward pressure to the fourth slide 71 is connected to the top of the fourth slide 71.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The intelligent flipping device of this invention includes a pushing detection component located at the end of the detection conveying trough and a flipping component located between the detection conveying trough and the unloading conveying trough. The pushing detection component utilizes the characteristic that the front of the steel sheet will have a collapsed corner area to determine the orientation of the front and back of the steel sheet by pushing against the side of the steel sheet. Based on the judgment result of the pushing detection component, the operation of the flipping component can be precisely controlled, thereby intelligently flipping the steel sheet in a targeted manner. This ensures that all steel sheets entering the unloading conveying trough after passing through the detection conveying trough and the flipping component are front-side up, ensuring consistency in subsequent processes. As mentioned above, using this intelligent flipping device avoids the problem of diffuse reflection detection results being affected by the electroplating of the steel sheet in traditional detection methods. Moreover, since this invention utilizes the characteristics of steel sheet stamping to detect the front and back by pushing, there is no need to specially set grooves on the steel sheet for detection. This significantly improves detection efficiency and reduces the production cost increased by setting grooves. Attached Figure Description

[0026] The following examples further illustrate the features and other related characteristics of the present invention in detail, to facilitate understanding by those skilled in the art:

[0027] like Figures 1 to 9 As shown, a smart steel plate flipping device for a weight scale includes a detection conveying trough 1 and a feeding conveying trough 2 connected in sequence. The detection conveying trough 1 is used to receive steel plates 3 with uncertain front and back orientations from upstream processes. The feeding conveying trough 2 is used to feed steel plates 3 with their front facing up to downstream processes. The detection conveying trough 1 is provided with a push detection component that identifies the front and back of the steel plate by pushing the side of the steel plate 3. A flipping component 4 capable of flipping the steel plate 3 is provided between the detection conveying trough 1 and the feeding conveying trough 2. The flipping component 4 flips or does not flip the steel plate 3 after passing through the flipping component 4 according to the detection result of the push detection component.

[0028] Due to the inherent characteristics of the stamping process, the front edge of the steel sheet 3 formed by stamping will form a collapsed corner area 31 due to pressure. The collapsed corner area 31 is generally presented as an arc surface located on the front edge.

[0029] The intelligent flipping device of this invention includes a pushing detection component located at the end of the detection conveying trough 1 and a flipping component 4 located between the detection conveying trough 1 and the unloading conveying trough 2. The pushing detection component utilizes the characteristic that the front of the steel sheet 3 will produce a collapsed corner area 31 to determine the orientation of the front and back of the steel sheet 3 by pushing the side of the steel sheet 3. Based on the judgment result of the pushing detection component, the flipping component 4 can be precisely controlled to operate, thereby intelligently flipping the steel sheet 3 in a targeted manner. This ensures that all steel sheets 3 entering the unloading conveying trough 2 after passing through the detection conveying trough 1 and the flipping component 4 are front-facing, ensuring consistency in subsequent processes. As described above, using the intelligent flipping device of this invention avoids the problem of diffuse reflection detection results being affected by the electroplating of the steel sheet 3 in traditional detection schemes. Moreover, since this invention utilizes the stamping characteristics of the steel sheet 3 to detect the front and back by pushing, there is no need to specially set grooves on the steel sheet 3 for detection. This significantly improves detection efficiency and reduces the production cost increased by setting grooves.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 9As shown, preferably, the pressing detection assembly includes a clamping module 5 disposed above the end of the detection conveying groove 1 for applying pressure to the lower steel sheet 3. The pressing detection assembly also includes a pressing module 6 disposed on the side of the end of the detection conveying groove 1. The pressing module 6 includes a first slide 61 that can approach or move away from the detection conveying groove 1. The end of the first slide 61 near the detection conveying groove 1 is provided with an extension rod 62 that can be inserted into the detection conveying groove 1. The front end of the extension rod 62 is provided with a tip 621. The bottom surface of the tip 621 is in contact with the bottom surface of the detection conveying groove 1, and the top surface is perpendicular to the tip. The tip 621 gradually rises towards the first slide 61. When the steel sheet 3 at the end of the detection conveying groove 1 is facing down, the tip 621 can be inserted into the bottom of the steel sheet 3 along the collapsed corner area 31 of the steel sheet 3 as the first slide 61 approaches the detection conveying groove 1. When the steel sheet 3 at the end of the detection conveying groove 1 is facing down, the tip 621 cannot be inserted into the bottom of the steel sheet 3. The pushing module 6 also includes a first photoelectric sensor 63 for detecting whether the first slide 61 has moved into place. When the tip 621 cannot be inserted into the bottom of the steel sheet 3, the first slide 61 cannot move into place and triggers the first photoelectric sensor 63.

[0031] As described above, when the pressing detection assembly of this application detects the steel sheet 3, the pressing module 6 controls the first slide 61 to move towards the detection conveying groove 1. This allows the first slide 61 to drive the extension rod 62 to press the side of the steel sheet 3. If the steel sheet 3 is facing upwards (i.e., the collapsed corner area 31 is on the upper surface), the tip 621 cannot penetrate the bottom of the steel sheet 3 through the collapsed corner area 31, thus obstructing the movement path of the first slide 61 and preventing it from moving into position to trigger the first photoelectric sensor 63. However, if the steel sheet 3 is facing downwards (i.e., the collapsed corner area 31 is on the lower surface), the tip 621 can penetrate the bottom of the steel sheet 3 through the collapsed corner area 31, and the first slide 61 can move into position to trigger the first photoelectric sensor 63. Thus, the orientation of the steel sheet 3 can be determined based on the triggering status of the first photoelectric sensor 63. The pressing detection assembly of this application also includes a clamping module 5. By clamping the steel sheet 3 downwards using the clamping module 5, it can be ensured that the steel sheet 3 will not detach from the detection conveying groove 1 under the pressure of the pressing module 6.

[0032] like Figures 1 to 5As shown, preferably, the pushing module 6 further includes a guide rail 64 extending laterally perpendicular to the end side of the detection conveying groove 1. The first slide 61 is movably connected to the guide rail 64 and moves laterally. A second slide 65, which can move laterally, is also movably connected to the guide rail 64. The first slide 61 is located between the second slide 65 and the detection conveying groove 1. A first compression spring 66 is connected between the first slide 61 and the second slide 65. A limiting movable link 67 is also connected between the first slide 61 and the second slide 65 so that the two slides can move closer or further apart from each other within a certain range. One end of the limiting movable link 67 is fixed to the first slide 61, and the other end is movably connected to the second slide 65 and can move laterally relative to the second slide 65. The pushing module 6 also includes a first electric push rod 68 connected to the second slide 65 for driving the second slide 65 to move laterally along the guide rail 64. The first photoelectric sensor 63 is fixed to the guide rail 64.

[0033] As described above, the first slide 61 and the second slide 65 are both connected to the guide rail 64 and move coaxially. When the push module 6 performs the test, the first electric push rod 68 first drives the second slide 65 to move towards the test conveying groove 1. Since the first compression spring 66 is connected between the first slide 61 and the second slide 65, the first slide 61 can also move towards the test conveying groove 1 under the push of the first compression spring 66. In this way, the first compression spring 66 between the first slide 61 and the second slide 65 can form a buffer area, allowing the tip 621 to flexibly push the steel sheet 3, thereby avoiding hard contact between the tip 621 and the steel sheet 3 and damage to the steel sheet 3. After the test is completed, when the first electric push rod 68 drives the second slide 65 to retract, the second slide 65 can also use the limiting movable linkage 67 to pull the first slide 61 away from the test conveying groove 1.

[0034] Specifically, the relative distance between the first slide 61 and the second slide 65 is greatest when the first compression spring 66 is not compressed, and the relative distance between the first slide 61 and the second slide 65 is closest when the first compression spring 66 is compressed to its limit.

[0035] like Figures 1 to 5 As shown, preferably, a second photoelectric sensor 69 is also fixed on the guide rail 64 to detect whether the second slide 65 has moved to a designated position. When the second slide 65 moves to the designated position, the second photoelectric sensor 69 will be triggered. Based on the signal from the second photoelectric sensor 69, the first electric push rod 68 can be precisely controlled to stop driving the second slide 65 to move in a timely manner. At the same time, it can also ensure that the second slide 65 can stop at the same position every time it is detected, and ensure that the first compression spring 66 can apply a constant thrust to the first slide 61 during detection to push the steel sheet 3 to ensure the consistency of detection.

[0036] like Figures 1 to 5 As shown, preferably, the clamping module 5 includes a third slide 51 that is movable up and down and is positioned above the end of the detection conveying trough 1. A first clamping arm 52 extending downward is connected to the third slide 51. A first roller 53 is rotatably connected to the first clamping arm 52 to facilitate rolling contact with the steel sheet 3 below. A second compression spring 54 is connected to the top of the third slide 51 to provide downward pressure. In this way, the first roller 53 can clamp the steel sheet 3 under the combined action of the gravity of the third slide 51 and the second compression spring 54 to prevent the steel sheet 3 from falling out of the detection conveying trough 1. At the same time, when the pushing detection component detects and lifts the steel sheet 3, it adaptively raises and maintains clamping to avoid damaging the steel sheet 3. In addition, the rolling contact between the first roller 53 and the steel sheet 3 can reduce friction and does not affect the conveying of the steel sheet 3.

[0037] like Figure 1 , Figure 6 , Figure 7 , Figure 8 As shown, preferably, the flipping assembly 4 includes a rotating seat 41 that is rotatable about a horizontal axis at the end of the detection conveying channel 1. The axis of rotation of the rotating seat 41 is perpendicular to the extension direction of the detection conveying channel 1. The rotating seat 41 is provided with a flipping groove 42 for the steel sheet 3 output from the end of the detection conveying channel 1 to enter. The flipping groove 42 is the same width as the steel sheet 3 and extends in the same direction as the extension direction of the detection conveying channel 1. The flipping groove 42 passes through the rotating seat 41. When the pushing detection assembly detects that the back side of the steel sheet 3 at the end of the detection conveying channel 1 is facing up, and the steel sheet 3 enters the flipping groove 42, the rotating seat 41 will rotate 180° to flip the steel sheet 3 to face up. When the pushing detection assembly detects that the front side of the steel sheet 3 at the end of the detection conveying channel 1 is facing up, and the steel sheet 3 enters the flipping groove 42, the rotating seat 41 will not move.

[0038] As described above, when the steel sheet 3 from the upstream process enters the inspection conveying trough 1, the steel sheet 3 at the end of the inspection conveying trough 1 will be pushed into the flipping trough 42 by the steel sheet 3 behind it. According to the detection result of the pushing detection component, if the steel sheet 3 entering the flipping trough 42 is facing up, the rotating seat 41 will rotate 180° to flip the steel sheet 3 over. Otherwise, the rotating seat 41 will not move.

[0039] When the detection conveyor trough 1 and the unloading conveyor trough 2 are set in the same direction and parallel, the next steel sheet 3 entering the tilting trough 42 can push the steel sheet 3 originally located in the tilting trough 42 to the unloading conveyor trough 2.

[0040] When the detection conveyor trough 1 and the unloading conveyor trough 2 are set vertically, such as Figure 1 , Figure 6 , Figure 7 , Figure 8As shown, preferably, the flipping assembly 4 further includes a second electric push rod 43. The rotating seat 41 is provided with a through hole 411 coaxially arranged with its rotation axis. The second electric push rod 43 is coaxially arranged with the rotating seat 41 and can extend through the through hole 411 to enter the flipping groove 42 and retract to exit the flipping groove 42. The flipping groove 42 also extends away from the second electric push rod 43 and penetrates the end face of the rotating seat 41 so that the second electric push rod 43 can push the steel sheet 3 in the flipping groove 42 in a direction perpendicular to the detection conveying groove 1.

[0041] As described above, if the detection conveying trough 1 and the unloading conveying trough 2 are set vertically, when the next steel sheet 3 is about to enter the tilting trough 42, the second electric push rod 43 can be controlled to extend into the tilting trough 42 along the through hole 411, pushing the steel sheet 3 originally located in the tilting trough 42 into the unloading conveying trough 2 in a direction perpendicular to the detection conveying trough 1. After the pushing is completed, the second electric push rod 43 retracts to avoid obstructing the subsequent steel sheet 3 from entering the tilting trough 42.

[0042] like Figure 1 and Figure 2 As shown, preferably, the intelligent flipping device further includes an anti-pullback component 7. The anti-pullback component 7 includes a fourth slide 71 that is movable up and down and is disposed above the inlet of the detection conveying trough 1. A second pressing arm 72 extending downward is connected to the fourth slide 71. A second roller 73 is rotatably connected to the second pressing arm 72 so as to make rolling contact with the steel sheet 3 below. A third compression spring 74 for providing downward pressure to the fourth slide 71 is connected to the top of the fourth slide 71.

[0043] During the manufacturing process, the steel sheet 3 is easily magnetized. When the magnetic steel sheet 3 is sent into the detection conveying tank 1, it may be pulled out of the detection conveying tank 1 again due to magnetic attraction.

[0044] As described above, in this case, the intelligent flipping device is also equipped with an anti-pull-back component 7 at the entrance of the detection conveying trough 1. With the help of the gravity of the fourth slide 71 and the elastic force of the third compression spring 74, the second roller 73 can apply downward pressure to the steel sheet 3 that has just entered the detection conveying trough 1 to increase the friction between the bottom of the steel sheet 3 and the surface of the detection conveying trough 1, thereby preventing the steel sheet 3 from being pulled out of the detection conveying trough 1 again due to the magnetic attraction.

[0045] As stated above, this case protects a smart flipping device for the steel plates of a weighing scale, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
