Description

Technical Field

[0001] The invention relates to the field of drill bit testing, and in particular to an auxiliary device for testing drill bit parameters and a detection device and method thereof. Background Art

[0002] A large number of CNC drills are needed in the PCB industry. In recent years, with the development of science and technology and the need to reduce costs, PCB CNC drills generally use welding knives, that is, the drill handle is uniformly made of white steel with a diameter of 3.175, and the diameter of the drill bit is set according to different specifications. It is generally made of tungsten steel and surface coated for special purposes.

[0003] CNC drill bits are the material with the highest cost besides base materials and precious metals, and have always been the focus of control by various manufacturers. In the process of use, the control method of combining grinding times and total length is generally adopted. In terms of incoming material inspection, the total length, diameter, and drill length of the drill bit are mainly checked. These parameters are related to the borehole diameter and the life of the drill bit. Due to the huge number of purchases, the actual number of random inspections accounts for a very low proportion of the total number.

[0004] The existing method of measuring length and diameter mainly relies on vernier calipers. The general vernier caliper has an accuracy of 0.01mm and can only display two digits. When measuring the length, due to the small diameter of the drill bit, the tightening and loosening of the caliper will cause the length to change. The caliper jaws are made of metal. If the drill bit is pressed too tightly, the tip of the drill bit will be crushed, causing the drill needle to be scrapped.

[0005] Some companies also use automatic grinders to measure drill bit length and diameter. The repeated measurement accuracy is poor, with an error of ±0.005mm. This error can offset the feed amount of one grinding. In addition, because the fully automatic drill bit grinder is expensive, the cost of using it for incoming material inspection is too high.

[0006] The second dimension is a professional device for measuring two coordinates that has become increasingly common in recent years. It can capture the image contour of the object to be measured through the set data, and can capture points, lines, circles, arcs, angles, and calculate various parameters based on the relative positions of its elements. By setting standard parameters and tolerances, it can realize automatic measurement and qualified judgment of parts and output inspection forms. Patent CN103206920B discloses a tool measuring device for a second dimension image measuring instrument. Its main function is to fix the horizontal axis and the drill bit through a V-clamp. It is not suitable for PCB drill bits with collars, and the structure is complex and cannot achieve batch measurement. The complex structure causes the height of the device to be too high and there is a risk of hitting the second dimension lens. For three-dimensional objects such as drill needles, automatic focus is required, and the measurement time is too long. There is currently no better way to solve the above problems.

[0007] When the two-dimensional imaging device measures the drill bit, it is necessary to extract the image of the object. Since the heights of the drill bit and the tail end of the drill shank are different, that is, the depth of field is different, focusing is required to extract the contour in the image. In addition, it is necessary to focus on both sides of the drill bit to obtain the image, and then infer the position of the drill head based on the two sides of the drill bit. The measurement method is cumbersome and the measurement efficiency is low. Summary of the invention

[0008] The present invention aims to solve one of the problems in the related art to at least a certain extent.

[0013] Furthermore, the limit baffle is connected to one end of the passage, and the head of the drill needle is connected to the other end of the passage. When the passage is connected, the conveyor belt stops working.

However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, mechanisms, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0034] The present application provides an auxiliary device for testing drill bit parameters, including an auxiliary plate, on which a limit baffle and a transmission component are arranged; the auxiliary plate is also provided with a first notch penetrating the auxiliary plate; when the drill bit is placed on the auxiliary plate, the transmission component acts on the drill bit, so that the head of the drill bit abuts against the limit baffle, and at the same time the tail of the drill bit is located in the first notch.

[0035] The present application provides a two-dimensional detection device for drilling needle parameter testing, which includes the above auxiliary device, a two-dimensional imaging device, and a fill light located under the auxiliary plate.

[0036] The present application provides a two-dimensional detection method for drilling bit parameter testing, comprising the following steps:

[0037] S1: placing the drill bit on the auxiliary plate, and the transmission component acts on the drill bit, so that the head of the drill bit abuts against the limit baffle, and the tail of the drill bit is located in the first notch;

[0038] S2: The fill light starts working;

[0039] S3: The two-dimensional imaging device scans the auxiliary plate to obtain the contour of the limit baffle and the contour of the drill shank tail, and calculates the drill bit parameters accordingly.

[0040] The reason why the first gap is set in this application is to ensure that the fill light under the auxiliary plate can pass through the first gap for fill light, so that when the two-dimensional image is scanned, the tail contour of the drill needle can be clearly scanned. The limit baffle is an upright vertical plate, and its contour is relatively clear and can be quickly captured by the two-dimensional image, so that the contour of the drill needle can be obtained and its parameters can be calculated.

[0041] The present application can obtain the contour of the drill bit tail with the help of the first notch in the auxiliary plate, and the contour of the drill bit head with the help of the position of the limit baffle, and then the length of the drill bit and other parameters can be obtained. The device and method of the present application have a simple structure, and can realize batch testing of drill bits with the help of two-dimensional imaging and auxiliary devices, and the test results are accurate.

[0042] Example 1

[0043] Please refer to the attached Figure 1-3 The present embodiment provides an auxiliary device for testing drill bit parameters, including an auxiliary plate 11, on which a limit baffle 13 and a transmission component are arranged; the auxiliary plate 11 is also provided with a first notch penetrating the auxiliary plate 11; when the drill bit is placed on the auxiliary plate 11, the transmission component acts on the drill bit, so that the head of the drill bit abuts against the limit baffle 13, and at the same time, the tail of the drill bit is located in the first notch.

[0044] The lengths of drill needles from the same batch are basically the same, and their lengths will not change much after the drill bits are worn. The first notch in the present application has a certain area, which can ensure that after the head of the drill needle abuts against the limit baffle 13, regardless of whether it is worn or not, its tail is located within the range of the first notch, thereby ensuring that in subsequent testing, the light emitted by the fill light passes through the first notch, making the outline of the tail of the drill needle clearly visible.

[0045] In order to improve the efficiency of drill bit measurement, the present application sets a plurality of protrusions and grooves on the same side of the limit baffle 13 facing the first notch, and the head of the drill bit abuts against the bottom of the groove in the limit baffle 13.

[0046] In order to further improve the efficiency of drill needle measurement, Figure 1 As shown, the present application sets the groove on one side of the limit baffle 13 as a protrusion on the other side, so that the drill can be placed on both sides of the limit baffle 13 for testing. The limit baffle 13 forms a bow-shaped upright vertical plate with orderly concave and convex, and the drill can be placed on both sides. At the same time, the position of the first notch and the position of the transmission component correspond to the position of the drill, ensuring that the present application can perform batch testing of drills at the same time.

[0047] In order to ensure that the head of the drill needle abuts against the limit baffle 13 under the drive of the transmission component, a second notch penetrating the auxiliary plate 11 is also provided on the auxiliary plate 11 of the present application. When the head of the drill needle abuts against the limit baffle 13, the head of the drill needle is located in the second notch. When obtaining the outline of the drill needle, the outline of the limit baffle 13 can be used as the outline of the drill needle head. The purpose of setting the second notch is to observe whether the drill needle abuts against the limit baffle 13 in the image; if the head of the drill needle does not abut against the limit baffle 13, the light of the fill light will be emitted through the second notch, indicating that the transmission before the drill needle test is not in place and needs to be re-transmitted and placed.

[0048] The drill needle in the present application includes a drill bit 22 and a drill shank 23. A drill needle collar 21 is provided on the drill shank 23. A limiting protrusion 15 is provided on the auxiliary plate 11. The limiting protrusion 15 is located between the limiting baffle 13 and the first notch, and is used to limit the drill needle collar 21. When placing the drill needle, the limiting protrusion 15 can preliminarily locate the position of the drill needle. The distance between the limiting protrusion 15 and the limiting baffle 13 is greater than the distance between the drill needle collar 21 and the limiting baffle 13, and the limiting protrusion 15 is a U-shaped groove structure, and the opening size of the groove is adapted to the outer diameter of the drill shank 23. When placing, the drill shank 23 is held by hand and placed in the U-shaped limiting protrusion 15, and the limiting protrusion 15 is located at the rear side of the drill needle collar 21, and is used to initially locate the position of the drill needle.

[0049] In this embodiment, the transmission assembly includes a spring ejector 14, which includes an ejector tube and a spring 141 and an ejector rod 142 located inside the ejector tube. One end of the spring 141 is fixed to the bottom of the ejector tube, and the other end is fixedly connected to the ejector rod 142. The ejector rod 142 is used to contact the tail of the drill needle.

[0050] The drill needle in this embodiment is placed as follows: hold the drill handle 23 so that the rear end of the drill handle 23 presses the tip of the push rod 142 in the spring push pin 14. At this time, the spring 141 is compressed by the rear end of the drill needle until the drill bit can enter the groove in the limit baffle 13, and then press the drill handle 23 into the U-shaped limit protrusion 15. At this time, the drill needle collar 21 is located between the limit protrusion 15 and the limit baffle 13; then slowly release the drill needle, and the drill needle is pushed by the spring 141 and the push rod 142 to move toward the limit baffle 13 until the drill bit 22 abuts against the limit baffle 13. The present application can ensure that the drill needle is tightened to abut against the limit baffle 13 and the spring thrust does not damage the drill bit by setting a suitable spring.

[0051] Example 2

[0052] The auxiliary device for drilling bit parameter testing provided in this embodiment is different from that in Embodiment 1 in that the transmission component is different. In this embodiment, the transmission component includes a transmission belt, which is located between the first notch and the limit baffle 13; when the drilling bit is placed on the auxiliary plate 11, the drilling bit is located on the transmission belt.

[0053] In this embodiment, the drill needles need to be tested in batches, so the conveyor belt can be set as a whole, which can simultaneously drive multiple drill needles located on the same side of the limit baffle 13 to move toward the limit baffle 13. The drill needle is placed on the conveyor belt, and the friction between the conveyor belt and the drill needle is used to transfer the drill needle to the groove of the limit baffle 13. The friction is small, so the head of the drill needle will not collide violently with the limit baffle 13, and the head of the drill needle can be ensured to be intact.

[0054] In the present application, the conveyor belt is located between the second notch and the limiting baffle 13, ensuring that the conveyor belt will not cover or affect the second notch, and will not affect the contour capture of the drill needle tail in subsequent tests.

[0055] Since the friction force is relatively small, it is necessary to ensure that the head of the drill needle is in contact with the limit baffle 13 before the two-dimensional image is scanned. The present application sets up a passage connected to both ends of the power supply, wherein the limit baffle 13 is connected to one end of the passage, and the limit baffle 13 is a conductive structure made of metal; the head of the drill needle is connected to the other end of the passage, and the drill bit is a conductive structure made of metal. When the passage is connected, it means that the head of the drill needle is in contact with the limit baffle 13, and the conveyor belt stops working. In order to accurately and quickly observe whether the passage is conductive, an indicator light or a buzzer or other device can be connected in series in the passage to timely indicate the on and off status of the passage.

[0056] In the present application, the conveyor belt located on the same side of the limit baffle 13 can be set as one, or a conveyor belt can be set for each drill bit; at the same time, the number of passages connected to the power supply corresponds to the drill bit, and it is necessary to detect whether the head of each drill bit is in contact with the limit baffle 13.

[0057] The drill needle is placed as follows in this embodiment: hold the drill handle so that it is placed on the conveyor belt, adjust the position of the drill needle so that the drill bit 22 can enter the groove in the limit baffle 13, and press the drill handle 23 into the U-shaped limit protrusion 15. At this time, the drill needle collar 21 is located between the limit protrusion 15 and the limit baffle 13; turn on the conveyor belt, and the drill needle is driven by the conveyor belt to move toward the limit baffle 13 until the passage is opened, and stop the conveyor belt.

[0058] Example 3

[0059] The auxiliary device for testing drill bit parameters provided in this embodiment is different from that in Embodiment 1 in that the transmission component is different. In this embodiment, the transmission component includes an electromagnet, and the first notch is located between the limit baffle 13 and the electromagnet. The electromagnet can be selected according to the material of the drill handle, and it generates thrust on the drill handle, so that the drill bit moves toward the direction close to the limit baffle 13.

[0060] In order to ensure that the drill bit is not damaged, you can choose the right type and size of electromagnet according to the material of the drill shank and the weight and model of the drill needle to avoid excessive thrust of the electromagnet on the drill shank, which may cause collision damage to the drill needle.

[0061] The drill needle in this embodiment is placed as follows: hold the drill handle 23, adjust the position of the drill needle so that the drill bit 22 can enter the groove in the limit baffle 13, and press the drill handle 23 into the U-shaped limit protrusion 15. At this time, the drill needle collar 21 is located between the limit protrusion 15 and the limit baffle 13; release the drill needle, and the drill needle moves toward the limit baffle 13 under the thrust of the electromagnet until the head of the drill needle abuts against the limit baffle 13.

[0062] Example 4

[0063] The present application provides a two-dimensional detection device for drilling needle parameter testing, including the auxiliary device in embodiments 1-3, a two-dimensional imaging device, and a fill light located below the auxiliary plate 11. The light emitted by the fill light can pass through the first notch and the second notch and be captured by the two-dimensional imaging device.

[0064] The present application provides a two-dimensional detection method for drilling bit parameter testing, comprising the following steps:

[0065] S1: Place the drill bit on the auxiliary plate 11, and use the transmission assembly in Example 1, Example 2, or Example 3 to transmit the drill bit to the position where the head of the drill bit abuts against the limit baffle 13. At this time, there is a second notch below the head of the drill bit and a first notch below the tail of the drill bit.

[0066] S2: placing the auxiliary plate 11 with the drill needle installed on the table of the two-dimensional imaging device; the fill light starts working;

[0067] S3: Operate the secondary element to automatically measure the data, taking the simple drill length parameter as an example:

[0068] S31: Operate the second dimension to read the lower left and lower right positioning holes 12 as a reference coordinate system for subsequent automatic positioning (when placing a board later, even if it is placed at any position, it is only necessary to read these two positioning holes 12, and the machine will automatically read the subsequent contour and size data based on the reference holes);

[0069] S32: Read the tail end contour of the first drill needle and set it as L1 (the drill needle of this tool has notches at both ends to facilitate the passage of light from the bottom and top, so as to identify a clear drill needle contour). Because the drill needle is pressed against the limit baffle 13, the position of the limit baffle 13 is equal to the position of the drill needle head. Read the contour of the limit baffle 13 and set it as L2. Measure the distance from L1 to L2 as the drill needle length, and set the tolerance and optimal value of the drill needle length.

[0070] S33: After the data is completed, click on the full-automatic test function, set the arbitrary position alignment, and align the two-dimensional imaging device with the positioning hole 12 of the auxiliary plate 11.

[0071] S34: The equipment runs fully automatic tests and automatically outputs reports.

[0072] In the present application, in addition to the first notch and the second notch, a corresponding notch can also be set at any position that needs to be measured to facilitate the passage of light emitted by the fill light and to facilitate the capture and calculation of the drill needle image by the two-dimensional imaging device.

[0073] The advantages of the present invention are that, compared with caliper measurement and grinder measurement, the measurement method of the present application has high accuracy; and can realize automatic measurement of batch drill bits;

[0074] The advantages of the present invention are that the device has a simple structure, low cost, and a low overall height (not exceeding 9.5 mm), thereby avoiding collision with a secondary dimension measurement lens.

[0075] The advantage of the present invention is that the automatic focus of the drill bit is omitted. The position of the limit baffle 13 is directly measured instead of inferring the top of the blade by measuring the two side edges of the drill bit through the limit baffle 13 of the drill bit. Only one data needs to be measured without automatic focus, and the measurement is more efficient.

[0076] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
