Description

Technical Field

[0001] This utility model relates to the field of cathode copper sampling technology, and in particular, to a standard sampling point positioning device for cathode copper plates. Background Technology

[0002] According to the requirements of the national standard for cathode copper (GB / T 467-2010) "5.3 Sampling and Sample Preparation Methods for Cathode Copper", cathode copper should be sampled using a drilling machine or punch press. Specifically, ten points should be taken from the cathode copper sample plate, nine of which should form a complete checkerboard pattern of three horizontal and three vertical lines, and one point should be located at the edge. Every four bundles of samples forming different four-sided edge samples should be taken. Using a drill bit or punch with a diameter of 10mm-20mm, drill or punch holes in a checkerboard pattern within a rectangle 100mm away from the cathode copper.

[0003] Traditional sampling point location methods rely on manual on-site measurement and positioning. This method is greatly affected by subjective factors, which may result in poor standardization and representativeness of the sampling points. Especially when taking the last sample from the four edges, abnormal local crystallization may occur during the growth of the cathode copper plate. The impurity elements in the crystallized areas are often outside the standard range. When manually locating sampling points, these points are deliberately avoided, which seriously interferes with the representativeness of the sampling.

[0004] Chinese patent CN203053734U discloses a cathode copper plate sampling machine. While this device can sample cathode copper plates, it cannot automatically generate sampling points, requiring manual measurement and positioning, which introduces human error. Therefore, there is a need for a cathode copper plate standard sampling point positioning device that can automatically generate sampling points, improving the standardization and representativeness of the sampling points. Utility Model Content

[0005] This invention provides a standard sampling point positioning device for cathode copper plates to solve the technical problem that the existing technology relies on manual measurement and positioning of sampling points, which is not objective and has poor representativeness.

The cathode copper plate standard sampling point positioning device is used to determine the position of the cathode copper plate sampling point. The device includes a copper plate sample placement platform, a standard point positioning disk, and a peripheral standard point positioning frame. The copper plate sample placement platform is used to place the cathode copper plate. The standard point positioning disk is mounted directly above and parallel to the copper plate sample placement platform.

[0010] Furthermore, the linear slide of the stepping single-axis lead screw is equipped with limiters on both the front and rear sides along its driving direction, and the distance between the two limiters is consistent with the width of the cathode copper plate.

[0011] Furthermore, the laser light strip includes 5-10 laser lights arranged at intervals in a direction perpendicular to its direction of movement.

[0012] Furthermore, the length of the laser strip is equal to the distance between the rectangular edge formed by the checkerboard-patterned standard sampling points on the cathode copper plate and the edge of the cathode copper plate.

[0015] Furthermore, the copper plate sample platform is equipped with spherical casters, which are used to support the cathode copper plate and assist in moving the cathode copper plate.

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0026] See Figures 1 to 4 An embodiment of the first aspect of this utility model provides a cathode copper plate standard sampling point positioning device. The cathode copper plate standard sampling point positioning device is used to determine the position of the cathode copper plate sampling point. The cathode copper plate standard sampling point positioning device includes a copper plate sample placement platform 1, a standard point positioning disk 2, and a peripheral standard point positioning frame 3. The copper plate sample placement platform 1 is used to place the cathode copper plate. The standard point positioning disk 2 is mounted directly above the copper plate sample placement platform 1 and parallel to the copper plate sample placement platform 1. A checkerboard-shaped standard point laser lamp 5 is provided on the standard point positioning disk 2. The checkerboard-shaped standard point laser lamp 5 is used to direct the laser light onto the cathode copper plate 14 to form a checkerboard-shaped standard sampling point. The peripheral standard point positioning frame 3 is installed around the standard point positioning disk 2. A laser light strip 6 is installed on the peripheral standard point positioning frame 3. The laser light strip 6 is used to form peripheral standard sampling points on the cathode copper plate.

[0027] The cathode copper plate standard sampling point positioning device described above includes a PLC controller and a power control cabinet 13 located below the copper plate placement platform 1. The PLC controller is connected to the peripheral standard point positioning frame 3 and is used to control the movement position of the laser light strip 6 on the peripheral standard point positioning frame 3. The power control cabinet is connected to an infrared proximity switch 11 and is used to control the on / off state of the standard point positioning disk 2 and the laser light strip 6 on the peripheral standard point positioning frame 3. The cathode copper plate standard sampling point positioning device is placed side by side with the sampling machine. The cathode copper plate 14 is placed on the copper plate placement platform 1, and the height of the copper plate placement platform 1 is the same as the height of the sampling machine, which facilitates the movement of the cathode copper plate to the sampling machine for sampling after the sampling point positioning is completed. The connecting rod 4 is positioned on one side of the standard point positioning disk 2, suspending the disk above the copper plate sampling platform 1. It is parallel to the lower cathode copper plate in both horizontal and vertical directions. A checkerboard-patterned standard point laser lamp 5 is installed on the standard point positioning disk 2. Directly shining this laser lamp onto the cathode copper plate 14 forms a checkerboard-patterned sampling point, specifically a checkerboard-style sampling point consisting of nine points arranged in a three-horizontal and three-vertical grid. Simultaneously, peripheral standard point positioning frames 3 are installed around the standard point positioning disk 2. The laser light strip 6 on the peripheral standard point positioning frames 3 is set by the PLC controller installation program, randomly illuminating one laser lamp to form the tenth sampling point at the edge.

[0028] See Figure 2 and Figure 4 This utility model sets up a checkerboard-shaped standard point laser lamp 5 on the standard point positioning disk 2, and the laser shines directly onto the cathode copper plate 14 to form a checkerboard-shaped standard sampling point; at the same time, a peripheral standard point positioning frame 3 is installed around the standard point positioning disk 2, and a laser light strip 6 is installed on the peripheral standard point positioning frame 3 to form peripheral standard sampling points. By using this device, the interference of human subjective factors is effectively overcome during the cathode copper plate sampling process, ensuring the objectivity and representativeness of the sampling and reducing the occurrence of sampling disputes.

[0029] In the embodiments of this application, the cathode copper plate standard sampling point positioning device further includes a connecting rod 4 connected to the standard point positioning disk 2. The connecting rod 4 is a height-adjustable structure, used to adjust the height of the standard point positioning disk 2 to accommodate workers of different heights. The connecting rod 4 can be a telescopic rod for height adjustment, a screw for height adjustment via thread, or other height-adjustable structures. By adjusting the height of the connecting rod 4, the height of the standard point positioning disk 2 can be adjusted. According to the requirements of the national standard for cathode copper (GB / T467-2010) "5.3 Cathode Copper Sampling and Sample Preparation Method", the edge of the rectangle formed by the checkerboard-patterned standard sampling points, directly shone by the laser lamp 5 onto the cathode copper plate, is 100mm away from the edge of the copper plate.

[0030] In the embodiments of this application, the checkerboard-style standard point laser lights 5 on the standard point positioning disk 2 are a three-vertical and three-horizontal checkerboard laser light array. The standard point positioning disk 2 is equipped with a three-vertical and three-horizontal checkerboard laser light array, that is, each row and each column is set with three parallel laser lights at intervals. When the power is turned on, the nine laser lights are lit at the same time and shine directly onto the lower copper plate to form nine standard sampling points, which can be manually marked.

[0031] See Figure 4 In the embodiments of this application, the peripheral standard point positioning frame 3 includes four sets of stepping single-axis lead screw linear slides 7 arranged in a rectangle. Each set of stepping single-axis lead screw linear slides 7 is equipped with a laser light strip 6. The laser light strip 6 is installed on the slider 8 of the stepping single-axis lead screw linear slide 7. The stepping single-axis lead screw linear slide 7 is used to drive the slider 8 to move to a preset position, thereby driving the laser light strip 6 to move to the preset sampling position through the slider 8. The four sets of stepping single-axis lead screw linear slides 7 are fixedly installed around the standard point positioning disk 2, and are parallel to the lower copper plate in both horizontal and vertical directions. As the height of the standard point positioning disk 2 is adjusted, the stepping single-axis lead screw linear slides 7 are connected to the PLC controller. After the peripheral sampling positioning frame is powered on, the PLC controller will start one of the linear slides 7 with laser lights according to the preset program. At this time, the laser light strip 6 on the slider 8 will randomly light up one laser light according to the preset program. At the same time, the stepper motor rotates the screw to push the slider 8 to move according to the preset travel distance (time) of the PLC. After reaching the preset distance, it stops. At this time, the laser light on the slide will shine on the copper plate. This is the tenth sampling point. The ten standard sampling points can be marked manually.

[0032] In the embodiments of this application, each set of stepper single-axis lead screw linear slides 7 is provided with limiters 9 on both the front and rear sides along its driving direction, and the distance between the front and rear limiters 9 is consistent with the width of the cathode copper plate. The limiters 9 are used to limit the movement range of the slider 8, so that the laser strip 6 on the slider 8 can only move within the width range of the cathode copper plate, ensuring that the tenth sampling point can be formed.

[0033] In the embodiments of this application, the laser light strip 6 comprises 5-10 laser lights arranged at intervals in a direction perpendicular to its moving direction. According to the requirements of the national standard for cathode copper (GB / T 467-2010) "5.3 Cathode Copper Sampling and Sample Preparation Methods," the tenth sampling point located at the edge should be set within 100mm of the rectangular edge formed by the standard points of the checkerboard pattern. Therefore, the laser light strip 6 consists of 5-10 laser lights, and one laser light is randomly lit each time, which can improve the randomness and objectivity of the sampling points.

[0034] In the embodiments of this application, the length of the laser light strip 6 is equal to the distance between the edge of the rectangle formed by the checkerboard-patterned standard sampling points on the cathode copper plate and the edge of the cathode copper plate. In this application, the distance between the two ends of the laser light strip 6 is 100mm, which is used to ensure that it can cover the 100mm edge of the lower cathode copper plate.

[0035] In the embodiments of this application, at least two right-angle locators 10 are provided on the copper plate sample stage 1. The right-angle locators 10 are used to fix the corner positions of the cathode copper plate. When positioning the standard sampling point, the cathode copper plate is placed inside the right-angle locator 10 to fix the position of the cathode copper plate.

[0036] In an embodiment of this application, the right-angle positioner 10 includes two positioning bars arranged at right angles, each equipped with a proximity switch 11. The proximity switches 11 control the power supply to the standard point positioning disk 2 and the peripheral standard point positioning frame 3 when the cathode copper plate is in position relative to the right-angle positioner 10. Two infrared proximity switches 11 are also provided inside the right-angle positioner 10, controlling the power supply to the upper electrical facilities by cutting off the infrared radiation through the cathode copper plate.

[0037] In the embodiments of this application, the copper plate sample placement platform 1 is equipped with spherical casters 12, which are used to support the cathode copper plate and assist in moving the cathode copper plate. The spherical casters 12 are spherical casters installed on the copper plate sample placement platform 1. The sampling machine and the cathode copper plate standard sampling point positioning device are placed side by side. Since the cathode copper plate is relatively heavy, after the sampling point positioning is completed, the cathode copper plate is directly pushed onto the sampling machine platform by the rolling of the spherical casters 12, which saves effort and facilitates the transportation of the cathode copper plate.

[0038] The method of using the cathode copper plate standard sampling point positioning device of this application is as follows:

[0039] 1. Manually place the cathode copper plate on the copper plate sample stage, ensuring that one side of the cathode copper plate is tightly against the right-angle locator;

[0040] 2. When the cathode copper plate is placed on the copper plate sample stage, the cathode copper plate blocks the infrared proximity switch, controlling the power supply of the chessboard sample positioning plate and the surrounding standard sample positioning frame suspended above the copper plate sample stage;

[0041] 3. After the nine laser lights on the chessboard-shaped positioning plate are powered on, they irradiate the lower cathode copper plate with laser beams, forming nine standard points;

[0042] 4. After the peripheral sample positioning frame is powered on, the PLC controller will start one of the stepper single-axis lead screw linear slides with laser lights according to the preset program. At this time, the laser lights on the slider will randomly light up one laser light according to the preset program. At the same time, the stepper motor rotates the lead screw to push the slider to start moving according to the preset travel distance (time) of the PLC. After reaching the preset distance, it stops. At this time, the laser light on the slider will shine on the cathode copper plate, which is the tenth sampling point.

[0043] 5. After the sampling points are located and marked manually with a marker, the cathode copper plate is manually pushed to the top of the sampling machine via the spherical casters to begin the sampling operation.

[0044] 6. After the cathode copper plate leaves the right-angle positioner, the infrared proximity switch on the copper plate sample stage is reconnected, and the power supply to the control device is cut off.

[0045] 7. When the next cathode copper plate begins to locate the sampling point, the PLC controller will start the stepping single-axis lead screw slide on the next set of peripheral sample positioning frame in a clockwise direction according to the preset program to ensure that the national standard requirement that "every four bundles of samples forming different four-sided edge samples should be taken" is met.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
