Description

Technical Field

[0001] This utility model relates to the field of cathode plate processing technology, specifically to an online edge-rolling detection device for cathode plates. Background Technology

[0002] In existing technologies, some cathode plates may exhibit edge curling during the production line process. These products are considered defective and need to be rejected through inspection. Currently, this is mainly done manually. However, this method has several drawbacks: firstly, manual inspection is easily affected by factors such as visual fatigue or judgment errors, leading to frequent missed detections and impacting product quality control; secondly, manual inspection is inefficient and cannot meet the demands of efficient and automated operations in modern production lines. Therefore, there is an urgent need to provide an online edge curling inspection device for cathode plates. Utility Model Content

[0003] The purpose of this invention is to provide an online edge-rolling detection device for cathode plates to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an online cathode plate edge curling detection device, comprising:

[0005] There are two upright columns, each with a support frame.

[0006] A conveyor frame is set between two supports, and a conveyor belt for conveying cathode plates is installed on it;

[0007] The detection mechanism is mounted on a support, on which a sensing plate is mounted. A proximity switch is mounted on the support. When the rolled edge of the cathode plate contacts the detection mechanism, the detection mechanism swings, causing the sensing plate to move relative to the proximity switch, thus displacing the sensing plate from the detection area of ​​the proximity switch.

[0008] As a further embodiment of this utility model: a limiting block for restricting the cathode plate is installed on the conveyor belt, and the limiting block is higher than the conveyor belt.

[0009] As a further embodiment of this utility model: the detection mechanism includes a first detection structure and a second detection structure, the number of brackets is four, and the four brackets are arranged in pairs, with the two groups of brackets located above and below the conveyor belt respectively, and the first detection structure and the second detection structure are respectively installed on the two groups of brackets, each of the first detection structure and the second detection structure is equipped with a sensing plate, and each of the two groups of brackets is equipped with a proximity switch corresponding to the sensing plate.

[0010] As a further embodiment of this utility model: the first detection structure includes two bearing supports, which are respectively installed on two brackets located above the conveyor belt, and a connecting rod is provided between the two bearing supports, and a detection cylinder is installed on the outer circumferential surface of the connecting rod.

[0011] As a further embodiment of this utility model: a limiting frame is installed on one of the brackets located above the conveyor belt. The limiting frame has two arc-shaped sliding grooves. A sensing plate is provided on the end face of the limiting frame near the connecting rod. The sensing plate is fixed on the limiting frame by two limiting pins inserted into the two arc-shaped sliding grooves respectively, and the connecting rod is connected to the end face of the sensing plate.

[0012] As a further embodiment of this utility model: a slot is provided at the bottom of the detection cylinder, and the number of the slots is two.

[0013] As a further embodiment of this utility model: the second detection structure includes two rotating rods, which are respectively connected to two supports located below the conveyor belt. A connecting frame is installed at the ends of the two rotating rods away from the supports, and an arc-shaped plate is installed on each of the two connecting frames.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This application sets the detection mechanism at a height that allows only normal cathode plates to pass through. When the cathode plate develops a rolled edge, the protruding rolled edge will contact the detection mechanism, causing the detection mechanism to swing and rotate the sensing element, causing it to deviate from the detection area of ​​the proximity switch. At this time, the proximity switch can no longer detect the sensing element and thus loses the signal. By monitoring the change in this signal, it can be determined whether the cathode plate has a rolled edge. Compared with traditional manual inspection, this detection method can identify cathode plates with thicknesses within an abnormal range online, with high detection efficiency and no missed detections.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 In this embodiment of the invention, an online edge-rolling detection device for a cathode plate includes:

[0026] Two upright columns 1, each equipped with a bracket 101;

[0027] The conveyor frame 2 is located between the two supports 101, and a conveyor belt 201 for conveying the cathode plate is installed on it;

[0028] The detection mechanism 3 is mounted on the bracket 101, on which a sensing plate 4 is mounted. A proximity switch 7 is mounted on the bracket 101. When the rolled edge of the cathode plate contacts the detection mechanism 3, the detection mechanism 3 swings and causes the sensing plate 4 to move relative to the proximity switch 7, so that the sensing plate 4 moves away from the detection area of ​​the proximity switch 7.

[0029] Specifically, each of the two columns 1 has a sliding groove. The bracket 101 is connected to the column 1 by bolts passing through the sliding groove. When it is necessary to adjust the distance between the detection mechanism 3 and the conveyor belt 201, the height of the bracket 101 can be adjusted first, and then bolts can be inserted into the corresponding positions of the sliding grooves and tightened to secure the bracket 101 to the column 1, thus completing the position adjustment. The conveyor frame 2 has a U-shaped structure, and the two columns 1 are fixedly connected to the two sides of the conveyor frame 2 respectively, thereby fixing the position of the conveyor frame 2. A conveyor belt 201 is provided on the upper surface of the conveyor frame 2, and a cathode plate is placed on the conveyor belt 201. The cathode plate is moved by the conveyor belt 201 and detected by the detection mechanism 3. The detection mechanism 3 and the conveyor belt 201 are then connected. The spacing between them allows the cathode plate without curled edges to pass through. The proximity switch 7 is fixed to the bracket 101 by a fixing frame. The model of the proximity switch 7 is SICK IME12-08NPSZC0S. Under normal conditions, the proximity switch 7 is aligned with the sensing plate 4. At this time, the sensing plate 4 is within the detection range of the proximity switch 7, which can provide it with a stable detection signal. When the cathode plate curls, its protruding part will contact the detection mechanism 3, causing the detection mechanism 3 to swing and drive the sensing plate 4 to rotate, causing it to deviate from the detection position of the proximity switch 7. At this time, the proximity switch 7 can no longer detect the sensing plate 4, thus "losing the signal". By this signal change, it can be determined whether the cathode plate has curled edges.

[0030] Please see Figure 4 In one embodiment, preferably, a limiting block 202 for limiting the cathode plate is installed on the conveyor belt 201. The limiting block 202 is higher than the conveyor belt 201. There are two conveyor belts 201, which are arranged in parallel. Multiple limiting blocks 202 are installed on each of the two conveyor belts 201. The cathode plate is placed on the two conveyor belts 201, and the multiple cathode plates are distinguished by the limiting blocks 202.

[0031] Please see Figure 1-2In one embodiment, preferably, the detection mechanism 3 includes a first detection structure 31 and a second detection structure 32. There are four supports 101, arranged in pairs. The two sets of supports 101 are located above and below the conveyor belt 201, respectively. The first detection structure 31 and the second detection structure 32 are respectively installed on the two sets of supports 101. The first detection structure 31 is located above the conveyor belt 201 and is used to detect the upward-curved cathode plate. The second detection structure 32 is located below the conveyor belt 201 and is used to detect the downward-curved cathode plate. Both the first detection structure 31 and the second detection structure 32 are connected to the column 1 through the supports 101 to provide stable support. Induction plates 4 are installed on both the first detection structure 31 and the second detection structure 32, and proximity switches 7 corresponding to the induction plates 4 are installed on both sets of supports 101 for simultaneous detection of the upward and downward curled edges of the cathode plate.

[0032] Please see Figure 2 In one embodiment, preferably, the first detection structure 31 includes two bearing supports 311, which are respectively mounted on two brackets 101 located above the conveyor belt 201. A connecting rod 312 passes between the two bearing supports 311, and a detection cylinder 313 is installed on the outer circumferential surface of the connecting rod 312. Furthermore, the connecting rod 312 is fixedly connected to the detection cylinder 313. When the detection cylinder 313 swings due to contact with the cathode plate, the connecting rod 312 will rotate accordingly. The bearing supports 311 provide stable support for the connecting rod 312 while ensuring its flexible rotation, preventing it from tilting during rotation.

[0033] Please see Figure 3 In one embodiment, preferably, a limiting frame 5 is installed on a bracket 101 located above the conveyor belt 201. The limiting frame 5 has two arc-shaped grooves 6. A sensing plate 4 is provided on the end face of the limiting frame 5 near the connecting rod 312. The sensing plate 4 is fixed to the limiting frame 5 by two limiting pins 8 inserted into the two arc-shaped grooves 6 respectively. The connecting rod 312 is connected to the end face of the sensing plate 4. The movement trajectory in the two arc-shaped grooves 6 matches the movement trajectory of the connecting rod 312 driving the sensing plate 4 and the limiting pins 8. This can ensure that the limiting pins 8 can move smoothly in the arc-shaped grooves 6, while limiting their range of motion and preventing the connecting rod 312 from rotating too much.

[0034] Please see Figure 4In one embodiment, preferably, a slot 314 is provided below the detection cylinder 313. There are two slots 314, and the position of the slot 314 corresponds to the position of the limiting block 202. Since the limiting block 202 is higher than the conveyor belt 201, when the limiting block 202 passes the detection cylinder 313, it can pass smoothly through the slot 314 without interfering with the detection cylinder 313.

[0035] Please see Figure 5 In one embodiment, preferably, the second detection structure 32 includes two rotating rods 321, which are respectively connected to two supports 101 located below the conveyor belt 201. A connecting frame 322 is installed at the end of each rotating rod 321 away from the supports 101, and an arc-shaped plate 323 is installed on each connecting frame 322. Further, the connecting frame 322 and the arc-shaped plate 323 are fixedly connected, and the connecting frame 322 rotates relative to the supports 101 via the rotating rods 321. Regarding rotation, specifically: the rotating rod 321 is rotatably connected to the bracket 101, while the rotating rod 321 is fixedly connected to the connecting frame 322. Alternatively, the rotating rod 321 can be fixedly connected to the bracket 101, while the rotating rod 321 is rotatably connected to the connecting frame 322. The sensing element 4 is fixedly mounted on the connecting frame 322. When the arc plate 323 swings due to contact with the downwardly rolled cathode plate, the sensing element 4 will rotate synchronously with the connecting frame 322 connected to it, thereby deviating from the detection position of the proximity switch 7.
