[0002] In modern enterprise production processes, it is sometimes necessary to measure or inspect products during production. In some scenarios where manual measurement is inconvenient or where high accuracy is required, such as in CNC engraving, visual recognition devices are usually used in conjunction with probe devices to measure various parameters and indicators of the products.

[0003] However, the processing environment of CNC engraving machines is relatively harsh, and a large amount of waste such as chips and residues are generated during the processing. When the vision recognition device and probe device are in motion and performing testing operations, these splashed chips will fly into the vision recognition device and probe device. Existing CNC engraving machines lack effective protection for the vision recognition device and probe device, which can easily lead to the obstruction of the operation of the vision recognition device and probe device due to chips and residues. Furthermore, when the vision recognition device and probe device are covered with chips and residues, their measurement accuracy will decrease. Utility Model Content

[0028] Please see Figures 1-3A visual recognition testing device for a precision engraving machine includes a hanging plate 1, a fixing plate 2, and a mounting plate 3. Two fixing plates 2 are disposed opposite each other on the lower sidewall of the hanging plate 1. The mounting plate 3 is connected to the end of the two fixing plates 2 away from the hanging plate 1. A measuring component 4 and a visual recognition component 5 are respectively disposed on the sidewall of the mounting plate 3 facing away from the hanging plate 1. A first protective cover 6 surrounds the measuring component 4 and the visual recognition component 5. A second protective cover 7 located inside the first protective cover 6 surrounds the visual recognition component 5. The bottom wall of the first protective cover 6 has through holes 61 and perforations 62. The bottom wall of the second protective cover 7 has light-transmitting holes 71 corresponding to the through holes 61. A chip-blocking component 8 is disposed at the through holes 61. A chip-blowing component 9 facing the measuring component 4 is disposed at the lower part of the mounting plate 3.

[0029] This utility model provides initial protection for the visual recognition component 5 and the measuring component 4 through the first protective cover 6, and further provides strict protection for the visual recognition component 5 through the second protective cover 7 to prevent light from interfering with the operation of the visual recognition component 5; the chip blocking component 8 blocks the debris, residue and other waste materials during operation, and the chip blowing component 9 blows away the accumulated metal residue and dust to avoid affecting the measurement accuracy of the measuring component 4.

[0030] Please see Figures 4-5 The measuring component 4 includes a base 41, a guide rail 42, a fixing block 43, a probe 44, a suspension plate 45, and a first cylinder 46. The base 41 is mounted on the side wall of the mounting plate 3. The guide rail 42 is laid on the side wall of the base 41 and extends vertically. The fixing block 43, with the probe 44 connected to its bottom end, is movably mounted on the guide rail 42. The suspension plate 45 is mounted on the upper side wall of the base 41. The first cylinder 46 is mounted on the suspension plate 45. The piston rod of the first cylinder 46 is connected downward to the fixing block 43, which drives the fixing block 43 and the probe 44 to move axially along the guide rail 42, so that the probe 44 passes downward through the through hole 62. In this embodiment, the fixing block 43 is movably mounted on the guide rail 42 by a slider.

[0031] Please see Figure 5 An upper buffer block 47 is provided on the upper side wall of the base 41, and an anti-collision post 48 is installed on the top surface of the fixing block 43, which is vertically opposite to the upper buffer block 47. When the fixing block 43 and the ejector pin retract into the first protective cover 6 under the drive of the first cylinder 46, the first cylinder 46 stops driving when the anti-collision post 48 contacts the upper buffer block 47 upwards. At this time, the fixing block 43 moves upwards to its limit position and stops moving. In this embodiment, the anti-collision post 48 is made of rubber and plays a role in shock absorption and anti-collision.

[0032] Please see Figures 5-6A support plate 49 is connected to the bottom end of the base 41. Two hydraulic buffers 410 are arranged opposite each other on the support plate 49. Each hydraulic buffer 410 includes a main body 411 fixed to the support plate 49, a telescopic rod 412 telescopically disposed within the main body 411, and a crash cap 413 connected to the top of the telescopic rod 412. The crash cap 413 abuts against the bottom wall of the fixing block 43. Please refer to [link / reference]. Figure 7 In this embodiment, the bottom wall of the fixing block 43 has two accommodating grooves 431 at its two corners, and the anti-collision cap 413 abuts against the top wall of the accommodating groove 431. The hydraulic buffer 410 has the functions of reducing impact noise, improving mechanical operating efficiency and improving mechanical precision. When the fixing block 43 and the ejector pin extend downwards out of the first protective cover 6 under the drive of the first cylinder 46, when the anti-collision cap 413 collides with the top wall of the accommodating groove 431, it can greatly reduce the mechanical impact between the fixing block 43 and the anti-collision cap 413, making the first cylinder 46 less likely to be damaged, and also eliminating rebound force and reducing the pause time.

[0033] Please see Figure 7 The debris blowing assembly 9 includes a lower limiting block 91 disposed on the side wall of the base 41 and connected to the bottom end of the guide rail 42. The lower limiting block 91 has a stepped opening 911 on the side facing away from the base 41. The top surface of the stepped opening 911 has an upwardly protruding limiting portion 912, which is used to limit the downward movement of the fixing block 43. The side wall of the stepped opening 911 has several air holes 913 facing the limiting portion 912. In this embodiment, the air holes 913 are connected to an external air source and are used to blow air onto the surface of the limiting portion 912 to prevent debris, residue, and dust from accumulating on the surface of the limiting portion 912, thus avoiding affecting the accuracy of the probe 44's downward movement.

[0034] Please see Figures 3-4 The visual recognition component 5 includes a mounting bracket 51, a camera 52, a light source bracket 53, and a ring light source 54. The mounting bracket 51 is disposed on the upper side wall of the mounting plate 3, located on one side of the base 41. The top of the camera 52 is mounted on the mounting bracket 51, and the bottom of the camera 52 extends downward toward the light-transmitting hole 71. The light source bracket 53 is disposed on the lower side wall of the mounting plate 3, located above the light-transmitting hole 71. The ring light source 54 is mounted on the light source bracket 53. In this embodiment, the ring light source 54 provides illumination, and the camera 52 acquires image information through its lens and transmits it to the engraving machine so that the engraving machine can perform processing based on the image information.

[0035] Please see Figure 2 , Figure 4 as well as Figure 8The chip-blocking assembly 8 includes a cover plate 81, a pad 82, and a second cylinder 83. The cover plate 81 is movably disposed at the through hole 61. The pad 82 is fixed to the outer wall of the first protective cover 6. The second cylinder 83 is mounted on the pad 82, and the piston rod of the second cylinder 83 is connected to the cover plate 81 to drive the cover plate 81 to cover or open the through hole 61. When the camera 52 is working, the second cylinder 83 drives the cover plate 81 to open the through hole 61. When the camera 52 stops working, the second cylinder 83 drives the cover plate 81 to cover the through hole 61 to prevent debris, residue, and other waste materials from splashing into the first protective cover 6 and the second protective cover 7.

[0036] Please see Figure 8 The cover plate 81 includes a front cover portion 811 and a vent portion 812 vertically connected to the side of the front cover portion 811. The piston rod of the second cylinder 83 is connected to the front cover portion 811. Please refer to [link / reference]. Figure 2 The first protective cover 6 is provided with guide plates 63 on both sides of the through hole 61, and guide grooves are respectively opened on the opposite sides of the two guide plates 63. The cover part 812 is slidably disposed in the two guide grooves. In this embodiment, the front cover part 811 is L-shaped and blocks one side of the first protective cover 6 to prevent debris, residue and other waste materials from entering the through hole 61 and the first protective cover 6 through the gap between the cover part 812 and the bottom wall of the first protective cover 6, thereby improving the protective effect.

[0037] Please see Figure 4 The hanging plate 1, the fixing plate 2 and the mounting plate 3 form a cavity, in which a spindle and a cutting tool connected to the bottom of the spindle for machining the workpiece are installed.
