Abstract
Description
Technical Field
[0001] This invention relates to the technical field of detecting defects in electrode machining, and in particular to an automated detection device and method for detecting defects in electrode machining. Background Technology
[0002] A workshop produced a batch of such Figures 1-3 The electrode shown is used for mounting onto an electronic product. The electrode includes a square plate 1 and a circular column 2 fixed on the top surface of the square plate 1. The circular column 2 has four oblique openings 3 on its cylindrical surface and around its circumference. The two oblique openings 3 on the left side form a V shape, and the two oblique openings on the right side form a V shape.
[0003] Due to the manufacturing process, some poles only had one or two bevels 3 machined on them, while the actual requirement was to machine four bevels 3 on each pole. Therefore, the workers were required to inspect each pole for manufacturing defects.
[0004] The method for detecting defects in electrode post machining within the workshop is as follows:
[0005] S1. The worker takes out a pole to be tested from the material basket and holds the square plate 1 of the pole by hand. Then, the square plate 1 is rotated, and the square plate 1 drives the circular column 2 to rotate synchronously. During the rotation, the worker observes the circular column 2 of the pole.
[0006] If only 1 to 3 bevels are observed on the electrode post, it indicates that the electrode post being inspected has a processing defect, and the worker will determine that the electrode post is a defective product; if four bevels are observed on the electrode post, it indicates that the electrode post being inspected does not have a processing defect, and the worker will determine that the electrode post is a qualified product, thus completing the inspection of a electrode post for processing defects.
[0007] S2. By repeating step S1 multiple times, workers can detect machining defects in a batch of pole pieces.
[0008] However, while the in-workshop inspection methods can detect processing defects in a batch of electrode posts, they still have the following technical limitations:
[0009] Workers can only inspect the terminal blocks for machining defects one by one, and with up to 600 terminal blocks to be inspected per day, it takes a very long time to complete all 600, which undoubtedly reduces the efficiency of defect detection. To solve this problem, more workers need to be added to the inspection team, which undoubtedly increases the inspection cost.
[0010] Therefore, there is an urgent need for a detection device and method that can reduce detection costs and greatly improve the efficiency of detecting defects in pole piece machining. Summary of the Invention
[0011] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automated detection device and method for detecting defects in pole piece processing.
[0012] The objective of this invention is achieved through the following technical solution: an automated detection device for detecting defects in the machining of electrode posts, comprising a lead screw module longitudinally fixed to a worktable surface, a longitudinally arranged strip seat fixed to the top surface of the movable plate of the lead screw module, a plurality of protrusions fixed to the top surface of the strip seat along its length, and a positioning plate fixed to the front and rear sides of each protrusion; a bracket located on the left side of the lead screw module is also fixed to the worktable surface, and a transverse mounting plate extending to the right and directly above the lead screw module is fixed to the front end of the bracket, and two detection components are arranged on the front end surface of the transverse mounting plate, the two detection components being located on the left and right sides of the lead screw module respectively;
[0013] The detection component located on the left includes a horizontal cylinder fixed on the front end face of the horizontal mounting plate. A vertical plate is fixed on the working end of the piston rod of the horizontal cylinder. A horizontally arranged rectangular shell is fixed on the bottom end of the vertical plate. An end cap is fixed on the left end face of the rectangular shell. A through groove communicating with its inner cavity is opened on the bottom wall of the rectangular shell.
[0014] The detection component on the left also includes a movable plate disposed inside the rectangular shell. The left end of the movable plate is slidably installed in the inner cavity of the rectangular shell. A spring is fixed between the left end face of the movable plate and the end cap. The right end of the movable plate extends outside the rectangular shell, and a light-transmitting hole is opened in the extension, penetrating through its front and rear ends. A connecting block is also fixed on the bottom surface of the left end of the movable plate, penetrating the through groove of the rectangular shell downward. The bottom end of the connecting block is connected to a clamping plate located directly below the rectangular shell. The clamping plate extends to the right side of the movable plate, and a V-shaped groove is opened in the extension end.
[0015] The detection assembly on the left also includes two laser beam sensors fixed on the right end face of the rectangular shell. The two laser beam sensors are located at the front and back of the movable plate, respectively. The beams emitted by the two laser beam sensors are both injected into the light-transmitting hole, and the two beams are directed at each other.
[0016] The spacing between any two adjacent bosses on the strip seat is equal, and the spacing between any two adjacent positioning plates is equal to the width of the square plate of the pole post.
[0017] The movable plate, rectangular shell, and clamping plate are arranged in parallel to each other.
[0018] The card plate end cap is detachably fixed to the left end face of the rectangular shell by locking screws.
[0019] The two detection components on the horizontal mounting plate are symmetrical.
[0020] The detection device also includes a controller, which is electrically connected to the lead screw module, the horizontal cylinder and the laser beam sensor via signal lines.
[0021] A method for automatically detecting defects in electrode post machining includes the following steps:
[0022] S1. The worker takes out multiple poles to be tested and places the square plate of the pole on the top surface of the boss on the strip seat. Since the distance between two adjacent positioning plates is equal to the width of the square plate of the pole, the multiple poles are respectively positioned on the bosses of the strip seat. At this time, the two oblique openings on the left side of the pole face to the left, while the two oblique openings on the right side of the pole face to the right.
[0023] S2. Control the moving plate of the lead screw module to move backward. The moving plate drives the strip seat to move backward synchronously. The strip seat drives the multiple poles installed on it to move backward synchronously. When the moving plate moves backward to the set distance, the controller controls the lead screw module to close. The first pole on the moving plate moves to the detection station of the two detection components. At this time, the circular column of the pole is still between the V-shaped groove of the clamping plate of the two detection components.
[0024] S3. The piston rods of the horizontal cylinders of the two detection components extend, and the piston rods drive the vertical plate to move toward the pole post. The vertical plate drives the rectangular shell, end cover, movable plate, clamping plate and two laser beam sensors to move synchronously toward the pole post. The V-shaped groove of the clamping plate moves toward the circular column of the pole post.
[0025] When the piston rod of the horizontal cylinder is fully extended, if one of the laser beam sensors sends an electrical signal to the controller, it indicates that the bevel was not machined on the circular column of the pole post, and the worker will then determine that the pole post is a defective product.
[0026] If none of the four laser beam sensors send an electrical signal to the controller, it means that the four bevels on the pole have not been missed in the machining process, indicating that the V-groove of the clamping plate has been inserted into the bevels. Therefore, the pole is determined to be a qualified product, thus completing the detection of a machining defect of a pole.
[0027] S4. After testing one pole post, the worker controls the horizontal cylinders of both testing components to retract. The piston rod drives the vertical plate to move away from the pole post. The vertical plate drives the rectangular shell, end cover, movable plate, clamping plate and two laser beam sensors to move away from the pole post in sync. Among them, the V-shaped groove of the clamping plate moves away from the circular column platform of the pole post.
[0028] S5. The worker repeats steps S2 to S4 multiple times to inspect all the poles on the bar seat for processing defects; after inspection, the worker removes the qualified or unqualified products from the bar seat.
[0029] S6. Workers can repeat steps S1 to S5 multiple times to detect processing defects in all poles in a batch in the workshop.
[0030] The present invention has the following advantages: reducing detection costs and greatly improving the efficiency of detecting defects in electrode processing. Attached Figure Description

[0046] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:
[0047] like Figures 4-11 As shown, an automated detection device for detecting defects in the machining of electrode posts includes a lead screw module 4 longitudinally fixed to a worktable. A longitudinally arranged strip seat 6 is fixed to the top surface of the moving plate 5 of the lead screw module 4. Multiple bosses 7 are fixed to the top surface of the strip seat 6 along its length. A positioning plate 8 is fixed to the front and rear sides of each boss 7. The distance between any two adjacent bosses 7 on the strip seat 6 is equal, and the distance between any two adjacent positioning plates 8 is equal to the width of the square plate 1 of the electrode post.
[0048] The workbench is also fixed with a bracket 9 located on the left side of the lead screw module 4. A horizontal mounting plate 10 extending to the right and directly above the lead screw module 4 is fixed at the front end of the bracket 9. Two detection components 11 are provided on the front end surface of the horizontal mounting plate 10. The two detection components 11 are located on the left and right sides of the lead screw module 4, respectively. The two detection components 11 on the horizontal mounting plate 10 are symmetrical.
[0049] The detection component 11 located on the left side includes a horizontal cylinder 12 fixed on the front end face of the horizontal mounting plate 10. A vertical plate 13 is fixed on the working end of the piston rod of the horizontal cylinder 12. A horizontally arranged rectangular shell 14 is fixed on the bottom end of the vertical plate 13. An end cap 15 is fixed on the left end face of the rectangular shell 14. A through groove 16 communicating with its inner cavity is opened on the bottom wall of the rectangular shell 14.
[0050] The detection component 11 on the left also includes a movable plate 17 disposed within a rectangular shell 14. The left end of the movable plate 17 is slidably installed in the inner cavity of the rectangular shell 14. A spring is fixed between the left end face of the movable plate 17 and the end cap 15. The right end of the movable plate 17 extends outside the rectangular shell 14, and a light-transmitting hole 18 penetrating its front and rear ends is opened in the extension. A connecting block 19 is also fixed on the bottom surface of the left end of the movable plate 17, penetrating the through groove 16 of the rectangular shell 14 downward. The bottom end of the connecting block 19 is connected to a retaining plate 20 located directly below the rectangular shell 14. The retaining plate 20 extends to the right side of the movable plate 17, and a V-shaped groove 21 is opened in the extension end. The movable plate 17, the rectangular shell 14, and the retaining plate 20 are arranged parallel to each other. The end cap 15 of the retaining plate 20 is detachably fixed to the left end face of the rectangular shell 14 by a locking screw.
[0051] The detection component 11 on the left also includes two laser beam sensors 22 fixed on the right end face of the rectangular shell 14. The two laser beam sensors 22 are located in front of and behind the movable plate 17 respectively. The beams emitted by the two laser beam sensors 22 are both injected into the light-transmitting hole 18, and the two beams are directed at each other.
[0052] The detection device also includes a controller, which is electrically connected to the lead screw module 4, the horizontal cylinder 12 and the laser beam sensor 22 via signal lines. The operator can control the lead screw module 4 to start or stop through the controller, and at the same time, can also control the extension or retraction of the piston rod of the horizontal cylinder 12, thus facilitating the operator's operation.
[0053] A method for automatically detecting defects in electrode post machining includes the following steps:
[0054] S1. The worker takes out multiple poles to be tested and places the square plate 1 of the pole on the top surface of the boss 7 on the strip seat 6. Since the distance between two adjacent positioning plates 8 is equal to the width of the square plate 1 of the pole, the multiple poles are respectively positioned on the boss 7 of the strip seat 6. At this time, the two oblique openings 3 on the left side of the pole face to the left, while the two oblique openings 3 on the right side of the pole face to the right.
[0055] S2. The moving plate 5 of the control screw module 4 moves backward. The moving plate 5 drives the strip seat 6 to move backward synchronously. The strip seat 6 drives the multiple poles installed on it to move backward synchronously. When the moving plate 5 moves backward to the set distance, the controller controls the screw module 4 to close. The first pole on the moving plate 5 moves to the detection station of the two detection components 11. At this time, the circular column 2 of the pole is still between the V-shaped groove 21 of the clamping plate 20 of the two detection components 11.
[0056] S3. The piston rod of the horizontal cylinder 12 of the two detection components 11 is extended. The piston rod drives the vertical plate 13 to move toward the pole post. The vertical plate 13 drives the rectangular shell 14, end cover 15, movable plate 17, clamping plate 20 and two laser beam sensors 22 to move toward the pole post in sync. Among them, the V-shaped groove 21 of the clamping plate 20 moves toward the circular column 2 of the pole post.
[0057] When the piston rod of the horizontal cylinder 12 is fully extended, if one of the laser beam sensors 22 sends an electrical signal to the controller [the reason why the laser beam sensor 22 sends an electrical signal to the controller is that the bevel 3 is not machined on the circular column 2 of the pole post, causing the unmachined part to push the clamping plate 20 outward, the clamping plate 20 drives the connecting block 19 to push outward, the connecting block 19 drives the movable plate 17 to push outward, the movable plate 17 compresses the spring, and at the same time, the light-transmitting hole 18 of the movable plate 17 is misaligned with the beam emitted by the laser beam sensor 22, the movable plate 17 blocks the beam emitted by the laser beam sensor 22, so the laser beam sensor 22 sends an electrical signal to the controller], it means that the bevel 3 is not machined on the circular column 2 of the pole post, and the worker judges the pole post to be a defective product;
[0058] If none of the four laser beam sensors 22 send an electrical signal to the controller, it means that the four bevels 3 on the pole piece have not been missed in the machining process, indicating that the V-groove 21 of the clamping plate 20 has been inserted into the bevel 3, and thus the pole piece is determined to be a qualified product, thereby completing the detection of a pole piece machining defect.
[0059] S4. After testing one pole post, the worker controls the horizontal cylinders 12 of the two testing components 11 to retract. The piston rod drives the vertical plate 13 to move away from the pole post. The vertical plate 13 drives the rectangular shell 14, end cover 15, movable plate 17, clamping plate 20 and two laser beam sensors 22 to move away from the pole post in sync. Among them, the V-shaped groove 21 of the clamping plate 20 moves towards the circular column 2 away from the pole post.
[0060] S5. The worker repeats steps S2 to S4 multiple times to inspect all the poles on the bar seat 6 for processing defects; after inspection, the worker removes the qualified or unqualified products from the bar seat 6.
[0061] S6. Workers can repeat steps S1 to S5 multiple times to detect processing defects in all poles in a batch in the workshop.
[0062] As shown in steps S2-S5, this detection device only needs the lead screw module 4 and the two detection components 11 working together to automatically and quickly detect whether the bevel 3 has been missed on the electrode post, thus enabling continuous detection of multiple electrodes on the strip seat 6. Therefore, compared to the detection methods in the workshop, this device eliminates the need for workers to inspect the electrode posts one by one for machining defects, enabling the rapid inspection of 600 electrodes per day, thereby shortening the detection time for machining defects and greatly improving the efficiency of electrode post machining defect detection.
[0063] Furthermore, only two workers are needed to inspect for machining defects in the poles, eliminating the need to add more workers and thus effectively saving on inspection costs.
[0064] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
