Abstract
Description
Technical Field
[0001] This application relates to the field of laser technology, and in particular to a laser cutting device. Background Technology
[0002] Laser cutting equipment can process workpieces such as glass substrates. To ensure the processing accuracy of the workpiece, the positional accuracy of the cutting head in the laser cutting equipment must be guaranteed. However, traditional laser cutting equipment often suffers from the defect of difficulty in accurately adjusting the position of the cutting head, which affects the positional accuracy of the cutting head and ultimately the processing accuracy of the workpiece. Utility Model Content
[0003] One of the technical problems addressed by this application is how to improve the machining accuracy of workpieces by laser cutting equipment.
[0004] A laser cutting apparatus, with reference to a first direction, a second direction, and a third direction that are mutually perpendicular, includes a base and a cutting mechanism, the cutting mechanism comprising:
[0005] The support member is rotatably connected to the base;
[0006] The carrier component is movably connected to the support component;
[0007] The cutting head is fixedly mounted on the carrier; and
[0008] A first adjustment unit is used to drive the support member to rotate relative to the base about an axis extending in the first direction; and
[0009] The second adjustment unit is used to drive the carrier to rotate relative to the support member about the axis extending in the second direction and the third direction.
[0010] In one embodiment, the carrier is slidably connected to the support along the first direction.
[0011] In one embodiment, the second adjustment unit includes a first pre-tightening component and a plurality of adjustment components. The carrier is slidably connected to the support member along the first direction via the first pre-tightening component. The adjustment components drive different positions of the carrier to slide relative to the carrier, so that the carrier rotates relative to the support member about a pivot extending in the second direction and the third direction.
[0012] In one embodiment, the number of adjustment components is four, and the four adjustment components are arranged in a matrix along the second direction and the third direction.
[0013] In one embodiment, the adjusting assembly includes an adjusting rod and a sleeve, the sleeve being fixedly connected to the support member, the adjusting rod extending along the first direction and passing through the support member and the sleeve and being threadedly connected to the sleeve, and the end of the adjusting rod having an adjusting convex spherical surface that abuts against the support member.
[0014] In one embodiment, the first preload assembly includes a preload bolt, a preload spring, a first preload pad, and a second preload pad. The preload bolt is fixedly connected to the support member and slidably passes through the carrier member. The first preload pad and the second preload pad are located inside the carrier member and sleeved on the preload bolt. The second preload pad is further away from the support member than the first preload pad. One of the first preload pad and the second preload pad has a preload convex spherical surface, and the other has a preload concave spherical surface that abuts against the preload convex spherical surface. The preload spring abuts between the second preload pad and the preload bolt along the first direction.
[0015] In one embodiment, the first adjustment unit includes a second pretensioning component and a drive component, the second pretensioning component mounting the support member on the base, and the drive component driving the support member to rotate relative to the base.
[0016] In one embodiment, the first adjustment unit further includes a second pre-tightening assembly, and there are multiple second pre-tightening assemblies. Each second pre-tightening assembly includes a mounting bolt, a mounting spring, a first mounting pad, and a second mounting pad. The mounting bolt is fixedly connected to the support member and slidably passes through the carrier member. The first mounting pad and the second mounting pad are located inside the carrier member and sleeved on the mounting bolt. The second mounting pad is further away from the support member than the first mounting pad. One of the first mounting pad and the second mounting pad has a mounting convex spherical surface and the other has a mounting concave spherical surface that abuts against the mounting convex spherical surface. The mounting spring abuts between the second mounting pad and the mounting bolt along the second direction.
[0017] In one embodiment, the drive assembly includes a drive bolt that is threaded to the base and abuts against the carrier, wherein one of the drive bolt and the carrier has a drive convex spherical surface and the other has a drive concave spherical surface that abuts against the drive convex spherical surface.
[0018] In one embodiment, the cutting mechanism further includes a lifting assembly, which includes a lifting bolt that is threadedly connected to the support member and abuts against the carrier member in the third direction. The lifting bolt is capable of overcoming the weight of the carrier member to drive the carrier member to move in the third direction. The lifting bolt has a lifting convex spherical surface that abuts against the carrier member.
[0019] One technical advantage of one embodiment of this application is that, given that the cutting head is mounted on a carrier, and the carrier is mounted on a support, the carrier can rotate relative to the support about axes extending in a second and third direction, and the support can rotate relative to the machine base about an axis extending in a first direction, the cutting head can also rotate relative to the machine base about axes extending in the first, second, and third directions. This allows the cutting head to have multiple degrees of freedom of movement, thereby enabling accurate adjustment of the cutting head's position, improving the adjustment precision of the cutting head's position, ensuring that the cutting head can move to a designated position to process the workpiece, and thus improving the processing accuracy of the cutting head and the entire laser cutting device on the workpiece.

Detailed Implementation
[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0037] See Figure 1 , Figure 2 and Figure 3 This application provides a laser cutting device 10 for laser cutting workpieces such as glass substrates 1011. For ease of description, a first direction, a second direction, and a third direction that are mutually perpendicular are used as references. The first direction, the second direction, and the third direction are the extension directions of the three coordinate axes in a spatial rectangular coordinate system. For example, the first direction can be the X-axis direction, the second direction can be the Y-axis direction, and the third direction can be the Z-axis direction. The first direction and the second direction are both horizontal, and the third direction is vertical. For example, the first direction is the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction. The laser cutting device 10 includes a laser cutting unit 11, a lead screw mechanism 12, and a main unit. The lead screw mechanism 12 is mounted on the main unit. The laser cutting device 11 is slidably connected to the main unit along a third direction. The lead screw mechanism 12 drives the laser cutting device 11 to slide up and down relative to the main unit along a third direction, so that the laser cutting device 11 moves closer to or away from the workpiece, thereby appropriately adjusting the distance between the laser cutting device 11 and the workpiece so that the laser cutting device 11 can effectively process the workpiece. After the workpiece is processed, the laser cutting device 11 moves upward so that the processed workpiece can be removed.
[0038] See Figure 1 , Figure 2 and Figure 3In some embodiments, the laser cutting apparatus 11 includes a base 101 and a cutting mechanism 102, the cutting mechanism 102 being mounted on the base 101. A lead screw mechanism 12 is connected to the base 101, causing the lead screw mechanism 12 to drive the base 101 and the entire laser cutting apparatus 11 to move along a third direction. The cutting mechanism 102 includes a support member 100, a carrier member 200, a cutting head 300, a first adjustment unit 400, and a second adjustment unit 500. The support member 100 is rotatably connected to the base 101 about an axis extending in a first direction. For example, the support member 100 can be rotatably connected to the base 101 via a first pin 710. The first pin 710 passes through both the base 101 and the support member 100. The central axis of the first pin 710 extends along the first direction; therefore, the central axis of the first pin 710 can be understood as the axis around which the support member 100 rotates relative to the base 101. The carrier member 200 is movably connected to the support member 100. The cutting head 300 is fixedly mounted on the support member 200. The cutting head 300 moves synchronously with the support member 200 and is used to output laser light for processing the workpiece. The first adjustment unit 400 drives the support member 100 to rotate relative to the base 101 about an axis extending in a first direction. The second adjustment unit 500 drives the support member 200 to rotate relative to the support member 100 about axes extending in a second and third direction.
[0039] Therefore, given that the cutting head 300 is mounted on the carrier 200, which in turn is mounted on the support 100, and that the carrier 200 can rotate relative to the support 100 around axes extending in the second and third directions, while the support 100 can rotate relative to the base 101 around an axis extending in the first direction, the cutting head 300 can also rotate relative to the base 101 around axes extending in the first, second, and third directions. This allows the cutting head 300 to have multiple degrees of freedom of movement, thereby enabling accurate adjustment of its position, improving the precision of the position adjustment, and ensuring that the cutting head 300 can move to the designated position to process the workpiece, thus improving the processing accuracy of the cutting head 300 and the entire laser cutting device 11. It can be understood that the cutting head 300 rotates slightly relative to the base 101 around axes extending in the first, second, and third directions, thus effectively fine-tuning its position.
[0040] In some embodiments, the carrier 200 is slidably connected to the support 100 along a first direction, allowing different positions of the carrier 200 to move closer to or further away from the support 100 along the first direction. The first adjustment unit 400 includes a second pre-tensioning assembly 410 and a drive assembly 420. The second pre-tensioning assembly 410 mounts the support 100 onto the frame 101, and the drive assembly 420 drives the support 100 to rotate relative to the frame 101 about a pivot extending in a second direction. The second adjustment unit 500 includes a first pre-tensioning assembly 510 and a plurality of adjustment assemblies 520. The carrier 200 is slidably connected to the support 100 along the first direction via the first pre-tensioning assembly 510, and the adjustment assemblies 520 drive different positions of the carrier 200 to slide relative to the carrier 200, thereby allowing the carrier 200 to rotate relative to the support 100 about pivots extending in the first and third directions.
[0041] See Figure 4 , Figure 5 , Figure 6 and Figure 10 In some embodiments, the first pre-tightening component 510 can be a front-mounted first pre-tightening component 510, and the number of first pre-tightening components 510 can be multiple, such as three or four. The front-mounted first pre-tightening component 510 includes a pre-tightening bolt 511, a pre-tightening spring 512, a first pre-tightening pad 513, and a second pre-tightening pad 514. The pre-tightening bolt 511 is fixedly connected to the support member 100 and slidably passes through the carrier member 200, so that the carrier member 200 can slide relative to the pre-tightening bolt 511 in a second direction. The first pre-tightening pad 513 and the second pre-tightening pad 514 are located inside the bearing member 200 and are sleeved on the pre-tightening bolt 511. One of the first pre-tightening pad 513 and the second pre-tightening pad 514 has a pre-tightening convex spherical surface 5141 and the other has a pre-tightening concave spherical surface 5131 that abuts against the pre-tightening convex spherical surface 5141. The second pre-tightening pad 514 is further away from the support member 100 than the first pre-tightening pad 513. For example, the first pre-tightening pad 513 has a pre-tightening concave spherical surface 5131 and the second pre-tightening pad 514 has a pre-tightening convex spherical surface 5141. The preload spring 512 abuts against the second preload pad 514 and the preload bolt 511 in the first direction. For example, the preload spring 512 can be a rectangular spring. The preload spring 512 is sleeved on the screw of the preload bolt 511. The preload spring 512 abuts against the second preload pad 514 and the preload bolt 511 in the first direction, that is, the preload spring 512 abuts against the nut of the second preload pad 514 and the preload bolt 511.
[0042] See Figure 1 and Figure 2When the adjusting component 520 drives the support member 100 to move away from the carrier member 200, the preload spring 512 is compressed and stores energy. This means the adjusting component 520 overcomes the elastic force of the preload spring 512, causing the carrier member 200 to move away from the support member 100. When the preload spring 512 releases its pressure, it drives the carrier member 200 to move closer to the support member 100. Therefore, through the action of the adjusting component 520 and the preload spring 512, the movement of the support member 100 closer to or further from the carrier member 200 can be ensured, thereby changing the distance between the support member 100 and the carrier member 200. By setting the preload concave spherical surface 5131 and the preload convex spherical surface 5141, the carrier member 200 can move relative to the support member 100 at a reasonable angle to the first direction, preventing the carrier member 200 from jamming relative to the support member 100 during movement, thus effectively changing the distance between the support member 100 and the carrier member 200.
[0043] In some embodiments, the first preload assembly 510 may be a rear-mounted first preload assembly 510, and the number of first preload assemblies 510 may be multiple, such as three or four. The rear-mounted first preload assembly 510 also includes a preload bolt 511, a preload spring 512, a first preload pad 513, and a second preload pad 514. The preload bolt 511 is fixedly connected to the carrier 200 and slidably passes through the support 100, so that the support 100 can slide relative to the preload bolt 511 in a first direction. The first preload pad 513 and the second preload pad 514 are located within the support member 100 and sleeved on the preload bolt 511. One of the first preload pad 513 and the second preload pad 514 has a preload convex spherical surface 5141, and the other has a preload concave spherical surface 5131 that abuts against the preload convex spherical surface 5141. The second preload pad 514 is further away from the support member 200 than the first preload pad 513. For example, the first preload pad 513 has a preload concave spherical surface 5131, and the second preload pad 514 has a preload convex spherical surface 5141. A preload spring 512 abuts between the second preload pad 514 and the preload bolt 511 along a second direction. For example, the preload spring 512 can be a rectangular spring. The preload spring 512 is sleeved on the threaded rod of the preload bolt 511 and abuts between the second preload pad 514 and the nut of the preload bolt 511.
[0044] When the adjusting component 520 drives the support member 100 to move away from the carrier member 200, the preload spring 512 is compressed and stores energy. That is, the adjusting component 520 overcomes the elastic force of the preload spring 512, causing the support member 100 to move away from the carrier member 200. When the preload spring 512 releases its pressure, it drives the support member 100 to move closer to the carrier member 200. Therefore, through the action of the adjusting component 520 and the preload spring 512, the movement of the support member 100 closer to or further from the carrier member 200 can be ensured, thereby changing the distance between the support member 100 and the carrier member 200. By setting the preload concave spherical surface 5131 and the preload convex spherical surface 5141, the support member 100 can move relative to the carrier member 200 at a reasonable angle to the first direction, preventing the support member 100 from getting stuck relative to the carrier member 200 during movement, thus effectively changing the distance between the support member 100 and the carrier member 200.
[0045] Therefore, the second adjustment unit 500 may include only the front first pretension component 510, or only the rear first pretension component 510, or both the front and rear first pretension components 510.
[0046] See Figure 1 , Figure 3 and Figure 4In some embodiments, the number of adjusting components 520 can be four. These four adjusting components 520 are arranged in a matrix along the second and third directions, forming two rows and two columns. When the four adjusting components 520 are adjusted individually, different positions of the carrier 200 move relative to the support 100 along the first direction, thereby changing the distance between the carrier 200 and the support 100. This allows the carrier 200 to deflect slightly relative to the support 100 about the axes extending in the second and third directions. For example, when one row of adjusting components 520 arranged along the third direction moves while the other row remains stationary, the sliding distances of the carrier 200 relative to the positions of different adjusting components 520 relative to the support 100 differ, causing a slight deflection of the carrier 200 relative to the support 100 about the axis extending in the third direction. For example, when one row of adjusting components 520 arranged along the first direction moves, while the other row of adjusting components 520 arranged along the first direction remains stationary, the sliding distances of the carrier 200 and the corresponding positions of the different adjusting components 520 relative to the support 100 are also different, which can cause the carrier 200 to slightly deflect relative to the support 100 about the axis extending in the second direction. In other embodiments, the number of adjusting components 520 can be three, etc. Furthermore, when all four adjusting components 520 move simultaneously, the sliding distances of the carrier 200 and the corresponding positions of the four adjusting components 520 relative to the support 100 along the first direction are equal. This allows the carrier 200 to slide relative to the support 100 along the first direction, preventing the carrier 200 from rotating relative to the support 100.
[0047] See Figure 4 , Figure 6 and Figure 9In some embodiments, the adjusting assembly 520 includes an adjusting rod 521 and a sleeve 522. The sleeve 522 is embedded in and fixedly connected to the support member 200. The adjusting rod 521 extends along a first direction and passes through the support member 200 and the sleeve 522. The adjusting rod 521 slides through the support member 200 and is threadedly connected to the sleeve 522. The end of the adjusting rod 521 abuts against the support member 100. For example, when the adjusting rod 521 is tightened, it can be continuously inserted into the support member 200, thereby causing the support member 200 to move away from the support member 100 against the elastic force of the preload spring 512. This increases the distance between the support member 200 and the position corresponding to the adjusting rod 521 and the support member 100. For example, when the adjusting rod 521 is loosened, it can be continuously pushed out of the carrier 200, thereby causing the preload spring 512 to release energy and push the carrier 200 closer to the support 100. This reduces the distance between the carrier 200 and the position corresponding to the adjusting rod 521 and the support 100. The adjusting assembly 520 can be a standard part, thus its structure is simple and can reduce the manufacturing cost of the laser cutting device 11.
[0048] In some embodiments, the adjusting rod 521 has an adjusting convex spherical surface 5211 that abuts against the support member 100. By providing the adjusting convex spherical surface 5211, it is possible for the adjusting convex spherical surface 5211 to abut against the support member 100 in any direction. This ensures that the adjusting rod 521 and the support member 100 make effective contact, thereby effectively changing the distance between different positions of the carrier member 200 and the support member 100. This ensures that the carrier member 200 deflects slightly relative to the support member 100 about the axes extending in the second and third directions, thereby improving the position adjustment accuracy of the cutting head 300.
[0049] See Figure 1 , Figure 6 and Figure 7In some embodiments, there are multiple second pre-tightening components 410. The second pre-tightening components 410 and the first pre-tightening components 510 are structurally similar. Each second pre-tightening component 410 includes a mounting bolt 411, a mounting spring 412, a first mounting pad 413, and a second mounting pad 414. The mounting bolt 411 is fixedly connected to the base 101 and slides through the support member 100. The first mounting pad 413 and the second mounting pad 414 are located inside the support member 100 and are sleeved on the mounting bolt 411. One of the first mounting pad 413 and the second mounting pad 414 has a mounting convex spherical surface 4141 and the other has a mounting concave spherical surface 4131 that abuts against the mounting convex spherical surface 4141. The second mounting pad 414 is further away from the base 101 than the first mounting pad 413. For example, the first mounting pad 413 has a mounting concave spherical surface 4131 and the second mounting pad 414 has a mounting convex spherical surface 4141. The mounting spring 412 abuts against the second mounting pad 414 and the mounting bolt 411 in the second direction. For example, the mounting spring 412 can be a rectangular spring. The mounting spring 412 is sleeved on the thread of the mounting bolt 411 and abuts against the second mounting pad 414 and the nut of the mounting bolt 411.
[0050] It is understood that the mounting bolt 411 and the hole in the support member 100 form a clearance fit, resulting in a gap between the mounting bolt 411 and the support member 100 in the third direction. Similarly, the mounting spring 412, the first mounting pad 413, and the second mounting pad 414 all have gaps with the mounting bolt 411 in the third direction. When the drive assembly 420 applies torque to the support member 100 relative to the first pin 710, it can change the size of the gaps between the support member 100, the first mounting pad 413, the second mounting pad 414, and the mounting spring 412 and the mounting bolt 411 in the third direction. This allows the support member 100 to slightly deflect relative to the base 101 around the first pin 710, that is, the support member 100 rotates around an axis extending in the second direction.
[0051] See Figure 7 and Figure 8In some embodiments, the drive assembly 420 includes a drive bolt 421, which is threaded to the base 101 and abuts against the support member 200. One of the drive bolt 421 and the support member 200 has a drive convex spherical surface 4211, and the other has a drive concave spherical surface 210 that abuts against the drive convex spherical surface 4211. For example, the end of the drive bolt 421 has a drive convex spherical surface 4211, and the support member 200 also has a drive convex spherical surface 4211. By providing the drive concave spherical surface 210 and the drive convex spherical surface 4211, the drive bolt 421 can effectively abut against the support member 100, generating torque on the support member 100. For example, there can be two drive bolts 421. When one of the drive bolts 421 is tightened, the drive bolt 421 applies an abutting force to the support member 100, generating a positive torque, thereby driving the support member 100 to rotate forward relative to the base 101. When the other drive bolt 421 is tightened, it applies a resisting force to the support member 100, generating a reverse torque, thereby driving the support member 100 to rotate in the opposite direction relative to the machine base 101. This allows for reasonable adjustment of the deflection angles of the support member 100 and the entire cutting head 300 relative to the machine base 101 about the axis extending in the first direction, thereby improving the position adjustment accuracy of the cutting head 300 and consequently improving the workpiece machining accuracy. In other embodiments, the number of drive bolts 421 can be one, and two drive bolts 421 can apply torque in the same direction to the support member 100.
[0052] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the cutting mechanism 102 further includes a lifting assembly 600, which includes a lifting bolt 610. The lifting bolt 610 may have the same structure as the drive bolt 421. The lifting bolt 610 is threadedly connected to the support member 100 and abuts against the carrier member 200 in a third direction. The drive bolt 421 can overcome the gravity of the carrier member 200 to drive the carrier member 200 to move in a third direction. The lifting bolt 610 has a lifting convex spherical surface 611 that abuts against the carrier member 200. By setting the lifting convex spherical surface 611, the lifting bolt 610 can effectively abut against the carrier member 200 to push the carrier member 200 to move in a third direction, thereby fine-tuning the position of the cutting head 300 in the third direction, further improving the positional accuracy of the cutting head 300, and thus improving the processing accuracy of the workpiece.
[0053] See Figure 1 , Figure 2 and Figure 3The base 101 includes a base plate 1011 and a translation component 1012. The translation component 1012 can be a linear module and is mounted on the base plate 1011. There are two cutting mechanisms 102, referred to as the first cutting mechanism and the second cutting mechanism, respectively. The support member 100 of the first cutting mechanism is fixedly connected to the base plate 1011, thus the first cutting mechanism is a fixed cutting structure. The support member 100 of the second cutting mechanism is mounted on the translation component 1012, and the translation component 1012 drives the second cutting mechanism to slide along a first direction, thus the first cutting mechanism is a translational cutting structure. By providing two cutting mechanisms 102, the processing efficiency of the laser cutting device 11 can be improved. Furthermore, since the cutting mechanism 102 also includes a lifting assembly 600, the height difference between the two cutting heads 300 in a third direction can be effectively adjusted, thereby improving the processing accuracy of the workpiece.
[0054] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the laser cutting apparatus 11 further includes an imaging mechanism 800, which is mounted on the base 101. The imaging mechanism 800 includes imaging units 810 and a light source 830 spaced apart along a third direction. The imaging units 810 are used to take pictures of the workpiece, and the light source 830 is used to emit light, enabling the imaging units 810 to acquire clear images of the workpiece under the action of the light source 830, thereby achieving workpiece positioning. The imaging units 810 are capable of rotating relative to the base 101 along axes extending in the first, second, and third directions. This improves the positional accuracy of the imaging units 810, thereby improving the positioning accuracy of the workpiece and ultimately improving the processing accuracy of the workpiece.
[0055] See Figure 1 , Figure 2 and Figure 3The imaging mechanism 800 also includes a base 840, a first fixed base 850, a second fixed base 860, and a third fixed base 870. The base 840 is rotatably connected to the base 101 via a second pin 880. The second pin 880 passes through the base 840 and the base 101, so that the base 840 is rotatably mounted on the base 101 along an axis extending in a second direction. The central axis of the second pin 880 can be understood as the axis around which the base 840 rotates in the second direction. The imaging unit 810 includes a camera 811 and a lens barrel 812. The camera 811 and the lens barrel 812 can be threaded together to ensure that the camera 811 and the lens barrel 812 are coaxially arranged. The camera 811 is bolted to a first fixing seat 850. The first fixing seat 850 has a first elongated hole 851, and fasteners such as bolts are inserted into the first elongated hole 851, so that the fasteners fix the first fixing seat 850 to the base 840. The first elongated hole 851 extends in a third direction. When the installation position of the fastener in the first elongated hole 851 is changed, the first fixing seat 850 can slide relative to the base 840 in the third direction, thereby precisely adjusting the position of the camera 811 in the third direction. The second fixing seat 860 has a second elongated hole 861, through which fasteners such as bolts are inserted, thereby fixing the second fixing seat 860 to the base 840. The second elongated hole 861 extends along a second direction, and when the fasteners in the second elongated hole 861 are loosened, the second fixing seat 860 can slide relative to the base 840 along the second direction. The third fixing seat 870 is bolted to the second fixing seat 860 and clamps the lens barrel 812, so that the lens barrel 812 passes through the hole formed by the third fixing seat 870 and the second fixing seat 860. The light source 830 has a third elongated hole 831, through which fasteners such as bolts are inserted, thereby fixing the third fixing seat 870 to the base 840. The third elongated hole 831 extends in the third direction. When the installation position of the fastener in the third elongated hole 831 is changed, the light source 830 can slide relative to the base 840 in the third direction, thereby precisely adjusting the position of the light source 830 in the third direction.
[0056] Since the camera 811 is fixedly connected to the base 840 via the first fixed seat 850, when the base 840 is slightly deflected relative to the base 101 about the axis extending in the second direction, the camera 811 can be slightly deflected relative to the base 101 about the axis extending in the second direction. When it is necessary for the camera 811 to rotate about the first and third directions of the axis, the bolts connecting the camera 811 to the first fixed seat 850 can be loosened, and the third fixed seat 870 can be unloaded from the second fixed seat 860. Then, the fasteners in the second elongated hole 861 can be loosened, causing the second fixed seat 860 to slide relative to the base 840 in the second direction. This applies a torque to the camera 811 about the first and third directions of the axis, causing the camera 811 to deflect slightly about the first and third directions of the axis. After the deflection of the camera 811 is set, the third fixed seat 870 can be fixedly connected to the second fixed seat 860, and the fasteners can fix the second fixed seat 860 to the base 840, and also fix the camera 811 to the first fixed seat 850.
