Description

Technical Field

[0001] The invention relates to a device for producing a steel sheet for a weight scale, in particular to an intelligent turning device for a steel sheet for a weight scale. Background Art

[0002] The core principle of weighing scales is to convert the human body's gravity into an electrical signal for measurement through a sensor. The core component is usually a steel sheet strain sensor. When a person stands on the scale, gravity is transmitted to the steel sheet strain sensor through the mechanical structure, causing the steel sheet to deform. The strain gauge attached to the steel sheet will also produce micro-strain, so that the resistance value of the strain gauge will also change slightly. By using multiple steel sheet strain sensors to form a Wheatstone bridge circuit, the tiny resistance change is converted into a differential voltage signal, and the weight can be calculated by the processor after amplification and analog-to-digital conversion.

[0003] Steel sheet strain sensors usually use a stamped steel sheet as the main body. Due to defects in the stamping process, there are often certain differences in the sizes of the front and back sides of the steel sheet. If the strain gauges are not uniformly pasted on the front or back side, the consistency of the steel sheet strain sensor will be different, resulting in errors in the final measurement results. In response to this situation, it is often necessary to set a notch on one side of the steel sheet during the current production process, and then use diffuse reflection photoelectric sensors to judge the front and back sides of the steel sheet and screen them on the assembly line. However, the steel sheet often needs to undergo surface electroplating during the production process, which can easily cause the diffuse reflection photoelectric sensor to make misjudgments.

[0004] Therefore, how to overcome the above-mentioned defects and unify the front and back directions of the steel sheets on the production line has become an important issue that needs to be solved urgently by technical personnel in this field. Summary of the invention

[0026] The features of the present invention and other related features are further described in detail below through embodiments to facilitate understanding by those skilled in the art:

[0027] like Figures 1 to 9 As shown, an intelligent flipping device for steel sheets of a weight scale comprises a detection conveying trough 1 and a discharge conveying trough 2 connected in sequence, the detection conveying trough 1 is used to receive steel sheets 3 with uncertain front and back directions conveyed from an upstream process, the discharge conveying trough 2 is used to deliver steel sheets 3 facing upward to a downstream process, the detection conveying trough 1 is provided with a pushing detection component for identifying the front and back sides of the steel sheet by pushing the side of the steel sheet 3, a flipping component 4 capable of flipping the steel sheet 3 is provided between the detection conveying trough 1 and the discharge conveying trough 2, and the flipping component 4 flips or does not flip the steel sheet 3 passing through the flipping component 4 according to the detection result of the pushing detection component.

[0028] Due to the 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 generally appears as a curved surface located at the front edge.

[0029] The intelligent flipping device of this case includes a push detection component arranged at the end of the detection conveying trough 1 and a flipping component 4 arranged between the detection conveying trough 1 and the unloading conveying trough 2, wherein the push detection component can use the characteristic that the front of the steel sheet 3 will produce a collapsed angle area 31 to judge the front and back directions of the steel sheet 3 by pushing the side of the steel sheet 3, and according to the judgment result of the push detection component, it can accurately control whether the flipping component 4 is in motion, thereby intelligently flipping the steel sheet 3 in a targeted manner, so that all the steel sheets 3 that pass through the detection conveying trough 1 and the flipping component 4 and enter the unloading conveying trough 2 are facing up to ensure the consistency of subsequent processes. As mentioned above, the use of the intelligent flipping device of this case can avoid the problem that the traditional detection scheme affects the diffuse reflection detection results due to the electroplating of the steel sheet 3, and because this case uses the characteristics of the stamping forming of the steel sheet 3 to detect the front and back sides by pushing, there is no need to deliberately set grooves on the steel sheet 3 for detection, which can greatly improve the detection efficiency and reduce the production cost increased by setting the grooves.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig. 9As shown, preferably, the push detection component includes a clamping module 5 arranged above the end of the detection conveying groove 1 for applying pressure to the steel sheet 3 below, and the push detection component also includes a pushing module 6 arranged on the side of the end of the detection conveying groove 1, and the pushing module 6 includes a first slide 61 that can approach / move away from the detection conveying groove 1, and the end of the first slide 61 close to the detection conveying groove 1 is provided with an extension rod 62 that can be inserted into the detection conveying groove 1, and 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 from the top. The tip 621 is gradually lifted toward the first slide 61, and when the steel sheet 3 moves to the end of the detection conveying groove 1 with the front side facing downward, the tip 621 can be inserted into the bottom of the steel sheet 3 along the collapsed angle area 31 of the steel sheet 3 as the first slide 61 approaches the detection conveying groove 1; when the steel sheet 3 moves to the end of the detection conveying groove 1 with the back side facing downward, 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 position; when the tip 621 cannot be inserted into the bottom of the steel sheet 3, the first slide 61 cannot move into position, triggering the first photoelectric sensor 63.

[0031] As described above, when the push detection assembly of this case detects the steel sheet 3, the push module 6 controls the first slide 61 to move toward the detection conveying groove 1, so that the first slide 61 can drive the extension rod 62 to push the side of the steel sheet 3. If the steel sheet 3 is facing up at this time, that is, the collapsed angle area 31 is located on the upper surface, the tip 621 cannot be inserted into the bottom of the steel sheet 3 through the collapsed angle area 31, and the moving path of the first slide 61 is therefore blocked and cannot move to the position to trigger the first photoelectric sensor 63; and if the steel sheet 3 is facing down at this time, that is, the collapsed angle area 31 is located on the lower surface, the tip 621 can be inserted into the bottom of the steel sheet 3 with the help of the collapsed angle area 31, and the first slide 61 can also move to the position to trigger the first photoelectric sensor 63. In this way, the front and back directions of the steel sheet 3 can be judged according to the triggering situation of the first photoelectric sensor 63. The push detection assembly of this application also includes a clamping module 5, which can ensure that the steel sheet 3 will not escape from the detection conveying groove 1 under the push of the push module 6 by pressing the steel sheet 3 downward by the clamping module 5.

[0032] like Figures 1 to 5As shown, preferably, the pushing module 6 also includes a guide rail 64 arranged on the end side of the detection conveying groove 1 and extending laterally perpendicular to the detection conveying groove 1, the first slide 61 is movably connected to the guide rail 64 for laterally movement, and the guide rail 64 is also movably connected to a second slide 65 that can move laterally, 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, and a limited movable link 67 is also connected between the first slide 61 and the second slide 65 so that the two slides can approach / move away from each other within a certain range, one end of the limited movable link 67 is fixed on the first slide 61, and the other end is limited and movably connected to the second slide 65 so that it 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, and the first photoelectric sensor 63 is fixed on the guide rail 64.

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

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

[0035] like Figures 1 to 5 As shown, preferably, a second photoelectric sensor 69 for detecting whether the second slide 65 has moved to the specified position is fixed on the guide rail 64, so that when the second slide 65 moves to the specified position, the second photoelectric sensor 69 will be triggered, and the first electric push rod 68 can be accurately controlled to stop driving the second slide 65 to move in time according to the signal of the second photoelectric sensor 69, and at the same time, it can also ensure that the second slide 65 can stop at the same position each 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 disposed above the end of the detection conveying trough 1 and capable of moving up and down, the third slide 51 is connected with a first clamping arm 52 extending downward, the first clamping arm 52 is rotatably connected with a first roller 53 for rolling contact with the steel sheet 3 below, and the top of the third slide 51 is connected with a second compression spring 54 for providing downward pressure to the third slide 51, so that the first roller 53 can press the steel sheet 3 under the dual action of the gravity of the third slide 51 and the second compression spring 54 to prevent the steel sheet 3 from escaping from the detection conveying trough 1, and at the same time, when the push detection component detects the lifting of the steel sheet 3, it is adaptively lifted and maintained to prevent damage to the steel sheet 3. In addition, the rolling contact between the first roller 53 and the steel sheet 3 can also reduce friction without affecting 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 which is arranged at the end of the detection conveying trough 1 and can rotate around a horizontal axis, the rotating axis of the rotating seat 41 is perpendicular to the extension direction of the detection conveying trough 1, and the rotating seat 41 is provided with a flipping groove 42 for the steel sheet 3 output from the end of the detection conveying trough 1 to enter, the flipping groove 42 is the same width as the steel sheet 3 and the extension direction is consistent with the extension direction of the detection conveying trough 1, the flipping groove 42 runs through the rotating seat 41, when the push detection assembly detects that the steel sheet 3 at the end of the detection conveying trough 1 is facing up with the back side 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 with the front side facing up, and when the push detection assembly detects that the steel sheet 3 at the end of the detection conveying trough 1 is facing up with the front side 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 of the upstream process enters the detection conveying trough 1, the steel sheet 3 at the end of the detection conveying trough 1 will be pushed into the flipping trough 42 by the steel sheet 3 behind. According to the detection result of the push detection component, if the steel sheet 3 entering the flipping trough 42 is facing up with the reverse side, 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 conveying trough 1 and the unloading conveying trough 2 are arranged in parallel in the same direction, the next steel sheet 3 entering the turning trough 42 can push the steel sheet 3 originally located in the turning trough 42 to the unloading conveying trough 2.

[0040] When the detection conveyor trough 1 and the unloading conveyor trough 2 are arranged vertically, as Figure 1 , Figure 6 , Figure 7 , Figure 8As shown, preferably, the flipping assembly 4 also includes a second electric push rod 43, and the rotating seat 41 is provided with a through hole 411 coaxially arranged with its rotating axis. The second electric push rod 43 is coaxially arranged with the rotating seat 41 and can extend out and enter into the flipping groove 42 through the through hole 411, and retract and exit the flipping groove 42. The flipping groove 42 also extends in a direction away from the second electric push rod 43 and penetrates the end face of the rotating seat 41 to facilitate the second electric push rod 43 to 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 conveyor trough 1 and the unloading conveyor trough 2 are arranged vertically, when the next steel sheet 3 is ready to enter the flip trough 42, the second electric push rod 43 can be controlled to extend into the flip trough 42 along the through hole 411, and the steel sheet 3 originally located in the flip trough 42 is pushed out in a direction perpendicular to the detection conveyor trough 1 into the unloading conveyor trough 2. After the pushing is completed, the second electric push rod 43 is retracted to avoid blocking the subsequent steel sheet 3 from entering the flip trough 42.

[0042] like Figure 1 and Figure 2 As shown, preferably, the intelligent flipping device also includes an anti-sucking back component 7, and the anti-sucking back component 7 includes a fourth slide 71 that is arranged above the entrance of the detection conveying trough 1 and can move up and down, and the fourth slide 71 is connected to a second clamping arm 72 extending downward, and the second clamping arm 72 is rotatably connected to a second roller 73 for rolling contact with the steel sheet 3 below, and the top of the fourth slide 71 is connected to a third compression spring 74 for providing downward pressure to the fourth slide 71.

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

[0044] As described above, in this case, the intelligent flipping device is also provided with an anti-suction 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 sucked out of the detection conveying trough 1 again due to magnetic adsorption.

[0045] As mentioned above, this case protects an intelligent flipping device for steel sheets on a weight scale. All technical solutions that are identical or similar to those in this case should be deemed to fall within the scope of protection of this case.
