Description

Technical Field

[0001] This invention relates to the field of metal inspection technology, and in particular to a device for detecting defects on the surface of copper plates. Background Technology

[0002] Copper plates are a type of metallic material, mainly composed of copper alloys. Depending on the application requirements, they may also contain other elements such as tin, lead, and phosphorus. During the production process of copper plates, in order to meet delivery standards, the quality of the copper plates needs to be inspected. Based on the defects on the surface of the copper plates, such as bumps, dents, and stains, the copper plates are classified into grades.

[0003] In the prior art, the detection devices for copper plate surfaces are usually visual detection methods that use cameras and image processing algorithms to detect defects, and sensor detection technologies that use specific sensors to detect defect particles on the copper plate surface. However, neither of these detection methods can identify abnormal protrusions on the copper plate surface, such as cleanable debris like copper shavings adhering during the production process, which leads to misjudgments and affects the detection results. Therefore, a copper plate surface defect detection device is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings mentioned above by providing a copper plate surface defect detection device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a copper plate surface defect detection device, used for copper plate surface detection, comprising:

[0006] A conveying device for conveying copper plates;

[0007] The detection device is mounted on the conveying device and is used to detect defects on the surface of the copper plate. The top wall of the detection device is provided with a cleaning component, a visual inspection mechanism and a defect detection component in sequence along the conveying direction of the conveying device.

[0008] The cleaning assembly consists of multiple sets of cleaning inclined rods. The cleaning inclined rods are inclined relative to the conveying direction of the copper plate and are in contact with the surface of the copper plate. A telescopic sleeve and a return spring for resisting the cleaning inclined rod to reset are provided on the side of the cleaning inclined rod away from the copper plate.

[0009] The scraping slant is provided with a trigger pin, and the scraping assembly also includes a locking mechanism that abuts against the trigger pin. The locking mechanism is provided with a connecting shaft, and the connecting shaft is provided with a pressure-sensing protrusion that extends to the outside of the connecting shaft and abuts against the rotation of the locking mechanism. The connecting shaft is provided with an abutment telescopic rod that is fixedly connected to the pressure-sensing protrusion. The abutment telescopic rod is used to retract when the contact force between the scraping slant and the protrusion exceeds a set threshold, so that the scraping slant scrapes off the protrusions on the copper plate surface and retracts when it cannot scrape them off.

[0010] Furthermore, the multiple sets of scraping slant bars are arranged in a conical shape to discharge the scraped debris from both sides of the scraping slant bars under the conveying of the conveying device.

[0011] Furthermore, the locking mechanism has a connecting hole corresponding to the connecting shaft, and the connecting hole has a missing part corresponding to the pressure measuring protrusion.

[0012] Furthermore, the locking mechanism is provided with a locking hook, and the side of the locking hook opposite to the trigger pin is provided with an inclined surface, so as to lock the cleaning bar when it is reset.

[0013] Furthermore, the defect detection component includes multiple detection levers that are inclined along the conveying direction of the copper plate;

[0014] A detection arc rod is provided on the side of the detection pendulum away from the copper plate. A contact ring corresponding to the detection arc rod is provided on the detection pendulum. A resistance sensing device is provided on the detection arc rod to detect the swing amplitude of the detection pendulum and thus detect the defect depth.

[0015] Furthermore, the detection device is provided with a mounting shaft that is rotatably connected to the detection swing arm, the detection swing arm is provided with a connecting ring corresponding to the mounting shaft, and a compression torsion spring is provided between the connecting ring and the mounting shaft.

[0016] Furthermore, the detection device is also equipped with a control unit and a power supply unit, and the control unit is electrically connected to the cleaning component, the visual inspection mechanism, the defect detection component and the power supply unit.

[0017] Furthermore, the visual inspection mechanism is arranged laterally within the inspection device, which includes an illumination component and a graphic recognition camera.

[0018] The beneficial effects of this invention are reflected in:

[0019] This invention, by setting a cleaning angled rod, retracts after contacting the protrusion, triggering a locking mechanism of a latch. A pressure-measuring protrusion within the locking mechanism hinders this rotation until the contact force exceeds a certain threshold. At this point, the pressure-measuring protrusion retracts, and the locking mechanism rotates to disengage from the trigger latch, allowing both the trigger latch and the cleaning angled rod to retract normally. This threshold is used to remove removable surface deposits, while recording protrusion defects present on the copper plate itself, thus improving detection accuracy. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-7 This invention discloses a copper plate surface defect detection device for detecting the surface defects of copper plate 01, comprising:

[0035] The conveying device 1 is used to convey the copper plate 01. It should be noted that the conveying device 1 is a common technical means in the prior art, so it is not described in detail. It can also be replaced by other structures that are easy for those skilled in the art to think of.

[0036] The detection device 2 is installed on the conveying device 1 and is used to detect defects on the surface of the copper plate 01. The top wall of the detection device 2 is provided with a cleaning component 3, a visual inspection mechanism 5 and a defect detection component 4 in sequence along the conveying direction of the conveying device 1.

[0037] The cleaning assembly 3 is composed of multiple sets of cleaning oblique rods 31. The cleaning oblique rods 31 are inclined relative to the conveying direction of the copper plate 01 and are in contact with the surface of the copper plate 01. A telescopic sleeve 32 and a reset spring 33 for resetting the cleaning oblique rod 31 are provided on the side away from the copper plate 01.

[0038] The scraping slant bar 31 is provided with a trigger pin 311. The scraping assembly 3 also includes a locking mechanism 34 that abuts against the trigger pin 311. The locking mechanism 34 is provided with a connecting shaft 341. The connecting shaft 341 is provided with a pressure measuring protrusion 342 that extends to the outside of the connecting shaft 341 and abuts against the rotation of the locking mechanism 34. The connecting shaft 341 is provided with a contact telescopic rod 343 that is fixedly connected to the pressure measuring protrusion 342. The contact telescopic rod 343 is used to retract when the contact force between the scraping slant bar 31 and the protrusion exceeds a set threshold, so that the scraping slant bar 31 scrapes off the protrusions on the surface of the copper plate 01 and retracts when it cannot scrape off the protrusions.

[0039] In order to identify abnormal protrusions on the surface of the copper plate, this application provides multiple sets of scraping inclined bars 31 in the conveying direction of the copper plate 01. The multiple sets of scraping inclined bars 31 are arranged in a conical shape to discharge the scraped debris from both sides of the scraping inclined bars 31 under the conveying of the conveying device 1. For adhesive protruding debris, the scraping inclined bars 31 can contact the protruding debris and abut against it to remove the adhesive protruding debris from the surface of the copper plate 01.

[0040] Regarding the integrated protrusion generated during the production of copper plate 01, after the scraping rod 31 contacts the protrusion, the scraping rod 31 retracts and triggers the locking mechanism 34 of the locking pin 311. The pressure-measuring protrusion 342 inside the locking mechanism 34 will hinder the rotation process until the contact force is greater than a certain threshold. Then the pressure-measuring protrusion 342 retracts, and the locking mechanism 34 rotates and disengages from the triggering pin 311, so that the triggering pin 311 and the scraping rod 31 can retract normally. It is easy to imagine that the locking mechanism 34 has a connecting hole corresponding to the connecting shaft 341, and the connecting hole has a missing part corresponding to the pressure-measuring protrusion 342.

[0041] Finally, after the scraping bar 31 disengages from the abnormal protrusion, it resets under the action of the return spring 33. At this time, the locking mechanism 34 rotates due to the contact of the trigger pin 311. Figure 7 As shown, the locking mechanism 34 is provided with a locking hook 344. The locking hook 344 and the trigger pin 311 are both provided with inclined surfaces on the opposite side, so as to lock the cleaning angle bar 31 when it is reset. During the reset process of the cleaning angle bar 31 under the action of the reset spring 33, the trigger pin 311 contacts the locking hook 344, readjusting the locking mechanism 34 to the initial state, so as to achieve the purpose of reset and facilitate the next inspection.

[0042] It should be noted in detail in this application that the defect detection component 4 includes a plurality of detection swing rods 41 that are inclined along the conveying direction of the copper plate 01;

[0043] A detection arc rod 42 is provided on the side of the detection swing rod 41 away from the copper plate 01. A contact ring 45 corresponding to the detection arc rod 42 is provided on the detection swing rod 41. A resistance sensing device is provided on the detection arc rod 42 to detect the swing amplitude of the detection swing rod 41 and thus detect the defect depth.

[0044] It is easy to imagine that the detection device 2 is provided with a mounting shaft 43 that is rotatably connected to the detection swing rod 41, the detection swing rod 41 is provided with a connecting ring corresponding to the mounting shaft 43, and a compression torsion spring 44 is provided between the connecting ring and the mounting shaft 43.

[0045] In this application, the detection device 2 is further provided with a control unit and a power supply unit. The control unit is electrically connected to the cleaning component 3, the visual inspection mechanism 5, the defect detection component 4 and the power supply unit. In addition, the strength of the contact telescopic rod 343 can be adjusted according to the hardness of the copper plate 01, and a counter can also be set in the contact telescopic rod 343. The counter is electrically connected to the control unit and is used to record data according to the movement process of the copper plate 01.

[0046] In this application, the visual inspection mechanism 5 is arranged horizontally within the inspection device 2. The inspection device 2 includes an illumination component and a graphic recognition camera. The visual inspection mechanism 5 is a commonly used technical means in the prior art, and therefore is not described in detail in this application.

[0047] Specifically, defect detection utilizes cameras and image processing algorithms. First, suitable lighting conditions are set on the copper plate, and the image of the copper plate surface is transmitted to a computer for processing. Then, image processing algorithms analyze the characteristics of the copper plate surface, such as color, shape, texture, and differences from an ideal surface. By setting certain thresholds and rules, defect particles and stains on the copper plate surface can be identified.

[0048] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0049] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0050] Additionally, "multiple" refers to two or more.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
