Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of laser, in particular to a bearing device and an inkjet printer comprising the same. BACKGROUND
[0002] The bearing device is used for placing a workpiece. Generally, the workpiece is placed on a bearing surface of the bearing device. In order to ensure the machining accuracy of the workpiece, it is necessary to ensure the parallelism of the bearing surface relative to a reference horizontal plane, that is, to avoid the bearing surface being inclined relative to the reference horizontal plane. However, for the conventional bearing device, when the parallelism of the bearing surface needs to be adjusted, the operation process is relatively complex, thereby affecting the convenience of the bearing operation. CONTENT OF THE UTILITY MODEL
[0003] One of the technical problems solved by the present application is how to improve the convenience of the bearing device.
[0004] A bearing device comprises:
[0005] a support member;
[0006] a bearing member arranged on the support member, a side of the bearing member away from the support member being used for placing a workpiece; and
[0007] an adjusting mechanism comprising at least two adjusting assemblies arranged at intervals, each adjusting assembly comprising an adjusting member, the bearing member being provided with a mounting space, the adjusting member being accommodated in the mounting space and being rotationally connected with the bearing member, the adjusting member being capable of driving the bearing member to approach or move away from the support member when the adjusting member rotates relative to the bearing member.
[0008] In one of the embodiments, the adjusting member is threadedly connected with the bearing member and abuts against the support member.
[0009] In one of the embodiments, the mounting space is a through hole, the through hole being provided with an internal thread structure, the adjusting member being provided with an external thread structure, and the external thread structure threadedly engages with the internal thread structure.
[0010] In one of the embodiments, a side of the through hole away from the support member has a mounting opening, and the adjusting mechanism further comprises a plugging member for plugging or opening the mounting opening.
[0011] In one of the embodiments, the adjusting assembly further comprises an abutting member arranged on a side of the adjusting member close to the support member, one of the abutting member and the adjusting member has a convex spherical surface, and the other has a concave spherical surface, the convex spherical surface and the concave spherical surface being in contact with each other.
[0012] In one of the embodiments, the support member is provided with a mounting groove on the side facing the adjusting member, and the abutting member is at least partially located in the mounting groove.
[0013] In one of the embodiments, the adjusting assembly further comprises a locking member, which is selectively in a locking state or an unlocking state. When in the locking state, the locking member is connected to the support member and restricts the movement of the adjusting member relative to the support member and the carrier. When in the unlocking state, the locking member is separated from the carrier and the adjusting member.
[0014] In one of the embodiments, the locking member comprises a locking rod and a limiting cap connected to the locking rod. When the locking member is in the locking state, the locking rod is arranged in the adjusting member and is threadedly connected to the support member, and the limiting cap and the support member jointly clamp the adjusting member.
[0015] In one of the embodiments, the number of the adjusting assemblies is at least three.

[0017] The carrier device according to any one of the above; and
[0018] An inkjet printing host, which is used for inkjet printing on a workpiece placed on the carrier of the carrier device.
[0019] One of the technical effects of one of the embodiments is that, since the adjusting mechanism comprises at least two adjusting assemblies arranged at intervals, when the carrier surface is inclined relative to the horizontal plane, the adjusting members of some or all of the adjusting assemblies can be rotated to drive the carrier and the corresponding local adjusting assemblies to move closer to or away from the support member, thereby avoiding the inclination of the carrier surface relative to the horizontal plane, and finally making the carrier surface and the horizontal plane parallel to each other, effectively ensuring the flatness of the carrier surface. Therefore, the flatness of the carrier surface can be adjusted only by rotating the adjusting members, thereby improving the convenience of using the carrier device. BRIEF DESCRIPTION OF DRAWINGS

[0034] Referring to Figure 1 , Figure 2 and Figure 3In an embodiment of the present application, a bearing device 10 is provided for placing a workpiece. The bearing device 10 comprises a support 100, a bearing 200 and an adjusting mechanism 300. The support 100 can be placed on a mounting plane (e.g. the ground). The adjusting mechanism 300 comprises at least two adjusting assemblies 301 arranged at intervals, each adjusting assembly 301 comprising an adjusting member 320. The bearing 200 is provided with a mounting space, and the adjusting member 320 is accommodated in the mounting space and rotationally connected to the bearing 200. The bearing 200 is arranged on the support 100, for example, the bearing 200 can be stacked on the support 100, and a side of the bearing 200 facing away from the support 100 is used for placing the workpiece. When the adjusting member 320 is rotated relative to the bearing 200, the adjusting member 320 is used to drive the bearing 200 to move closer to or further away from the support 100. In this way, the bearing surface 221 of the bearing 200 for bearing the workpiece can be adjusted, ensuring the planeness of the bearing surface 221, thereby improving the convenience of using the bearing device 10.
[0035] Referring to Figure 2 , Figure 3 and Figure 4 In some embodiments, the bearing 200 comprises a bearing box 210 and a cover plate 220, and the bearing box 210 and the cover plate 220 are fixedly connected in a detachable manner, for example, the bearing box 210 and the cover plate 220 are fixedly connected by a plurality of bolts. The bearing box 210 is located between the cover plate 220 and the support 100, and a vacuum cavity 211 is formed in the bearing box 210. The cover plate 220 covers the vacuum cavity 211, and a surface of the cover plate 220 in the thickness direction facing away from the bearing box 210 is a bearing surface 221, on which the workpiece is fixed. A plurality of adsorption holes 222 are recessed on the bearing surface 221, and the adsorption holes 222 have a relatively small diameter and extend through the entire cover plate 220 and communicate with the vacuum cavity 211. When the vacuum cavity 211 is subjected to vacuumizing treatment by a vacuum generator, a vacuum is also generated in the adsorption holes 222. When the workpiece is placed on the bearing surface 221 and covers the adsorption holes 222, the workpiece will be adsorbed on the bearing surface 221 under the action of the vacuum force of the adsorption holes 222, thereby realizing the fixation of the workpiece by the bearing 200.
[0036] Referring to Figure 2 , Figure 3 and Figure 4In some embodiments, in view of the fact that the adjusting mechanism 300 comprises at least two adjusting assemblies 301, each adjusting assembly 301 is arranged at a position spaced apart from each other. For example, the number of adjusting assemblies 301 can be at least three, and the number of adjusting assemblies 301 can be equal to the number of edges of a regular polygon, and each adjusting assembly 301 is arranged at a position corresponding to each corner of the regular polygon. In other words, each connecting line connecting the positions of the adjusting assemblies 301 can be an edge of the same regular polygon. For example, the number of adjusting assemblies 301 can be four, and the four adjusting assemblies 301 are arranged at positions corresponding to the four corners of a square. For another example, the number of adjusting assemblies 301 can be three, and the three adjusting assemblies 301 are arranged at positions corresponding to the three corners of an equilateral triangle. Of course, the number of adjusting assemblies 301 can also be greater than four.
[0037] Referring to Figure 4 , Figure 5 and Figure 6 , in some embodiments, the adjusting member 320 is threadedly connected to the carrier 200 and abuts against the support 100. In this way, the adjusting member 320 can be connected to the carrier 200 through an intermediate connecting member, and the connection structure between the adjusting member 320 and the carrier 200 is simplified, and the compactness of the carrier device 10 in structure is achieved.
[0038] Referring to Figure 4 , Figure 5 and Figure 6 , in some embodiments, the mounting space is a through hole 230, the through hole 230 is provided with an internal thread structure, and the adjusting member 320 is provided with an external thread structure, and the external thread structure is threadedly connected with the internal thread structure. By providing the through hole 230, the adjusting member 320 can make full use of the accommodation space of the through hole 230, thereby achieving the compactness design of the carrier device 10 in structure.
[0039] Referring to Figure 4 , Figure 5 and Figure 6 , in some embodiments, the adjusting assembly 301 further comprises a locking member 310, the locking member 310 can be selectively in a locked state or an unlocked state, the locking member 310 in the locked state is connected to the support 100 and limits the movement of the adjusting member 320 relative to the support 100 and the carrier 200; the locking member 310 in the unlocked state is separated from the support 100 and the adjusting member 320. The locking member 310 can effectively limit the movement of the adjusting member 320 along the axis of the adjusting member 320, and also facilitates the installation and disassembly of the adjusting member 320.
[0040] The locking member 310 is fixedly connected with the support member 100, the locking member 310 is arranged in the adjusting member 320, the adjusting member 320 can rotate relative to the locking member 310 around the central axis of the locking member 310, the central axis of the locking member 310 extends along the thickness direction of the bearing member 200, for example, the cover plate 220 and the bearing box 210 are provided with a through hole 230, the through hole is the mounting space, the through hole 230 penetrates the bearing surface 221, the adjusting member 320 is accommodated in the through hole 230, and it can be understood that the adjusting member 320 is hidden in the bearing box 210. The outer side circumferential surface of the adjusting member 320 is provided with an external thread structure, the inner side wall surface of the through hole 230 is provided with an internal thread structure, the external thread structure of the adjusting member 320 is engaged with the internal thread structure, so that the adjusting member 320 is connected with the bearing box 210 through the threaded pair. When the adjusting member 320 rotates relative to the locking member 310, the bearing box 210 moves away from or approaches the support member 100 through the transmission of the threaded pair. In popular terms, when the bearing box 210 and the entire bearing member 200 move away from the support member 100, the bearing member 200 rises; when the bearing box 210 and the entire bearing member 200 move close to the support member 100, the bearing member 200 descends.
[0041] In other embodiments, the locking member 310 can be replaced by a cam or slider link structure, when the adjusting member 320 rotates relative to the bearing member 200, the adjusting member 320 can also drive the bearing box 210 to move away from or approach the support member 100 through the cam or slider link structure, that is, the rotating adjusting member 320 can also drive the bearing box 210 to rise and descend.
[0042] Referring to Figure 4 , Figure 5 and Figure 6 In some embodiments, the locking member 310 includes a locking rod 311 and a limiting cap 312 connected with the locking rod 311, when the locking member 310 is in the locking state, the locking rod 311 is arranged in the adjusting member 320 and is threadedly connected with the support member 100, and the limiting cap 312 and the support member 100 jointly clamp the adjusting member 320. In this way, by arranging the limiting cap 312, the adjusting member 320 can be well limited in the axial direction.
[0043] For example, the locking rod 311 protrudes on one surface of the limiting cap 312 in the thickness direction, and the locking rod 311 can be coaxially arranged with the limiting cap 312. The limiting cap 312 has a cross-sectional dimension greater than that of the locking rod 311, and the adjusting member 320 is provided with a rotating hole 322, and the rotating hole 322 has a hole diameter smaller than the cross-sectional dimension of the limiting cap 312, so that the limiting cap 312 cannot enter the rotating hole 322, and the limiting cap 312 is located outside the rotating hole 322. The locking rod 311 is arranged in the rotating hole 322, and the end of the locking rod 311 is fixedly connected with the support 100, so that the locking member 310 is in a locking state. Therefore, in the locking state, the adjusting member 320 is abutted between the limiting cap 312 and the support 100, that is, the limiting cap 312 and the support 100 jointly clamp the adjusting member 320, so that the sliding of the adjusting member 320 in the axial direction of the locking member 310 is limited, in other words, the adjusting member 320 can only rotate relative to the locking member 310 around the central axis of the locking member 310, and the adjusting member 320 cannot slide in the axial direction of the locking member 310. It can be understood that the axial direction of the locking member 310 is the thickness direction of the bearing 200. Therefore, the relationship between the adjusting member 320 and the bearing box 210 can be similar to that between a screw rod and a nut. When the adjusting member 320 rotates, the bearing box 210 can move linearly in the axial direction of the locking member 310, that is, the rotational movement of the adjusting member 320 is converted into the linear movement of the bearing box 210, so that the bearing box 210 moves close to or away from the support 100.
[0044] Referring to Figure 4 , Figure 5 and Figure 6 In some embodiments, the locking rod 311 includes a threaded portion 3112 and a connecting portion 3111. The threaded portion 3112 is provided with an external thread structure, and the connecting portion 3111 is not provided with an external thread structure. The connecting portion 3111 is connected between the threaded portion 3112 and the limiting cap 312. The threaded portion 3112 is threadedly connected with the support 100, so as to realize the threaded connection between the locking rod 311 and the support 100. The connecting portion 3111 cooperates with the rotating hole 322, so that the adjusting member 320 can rotate relative to the connecting portion 3111 smoothly, reduces the frictional resistance generated between the adjusting member 320 and the locking rod 311 during the rotation of the adjusting member 320, improves the smoothness of the rotation of the adjusting member 320, and finally improves the convenience of the operation of the adjusting member 320. In other embodiments, the locking rod 311 can also be fixedly connected with the support 100 in a buckling connection manner. Figure 4 , Figure 5 and Figure 6In some embodiments, since the through hole 230 penetrates the bearing surface 221, the through hole 230 has a mounting opening 231 on the bearing surface 221, through which the adjusting member 320 can be installed into the through hole 230, so that the adjusting member 320 is accommodated in the through hole 230 of the bearing box 210, which can be understood as that the adjusting member 320 is located inside the bearing member 200, so that external impact can be effectively prevented from interfering with the adjusting member 320, and the adjusting member 320 can also be effectively prevented from interfering with the workpiece on the bearing surface 221. When it is necessary to rotate the adjusting member 320, the adjusting wrench can be inserted into the through hole 230 and contacted with the adjusting member 320, and the user can exert a torque on the adjusting member 320 through the adjusting wrench, so as to drive the adjusting member 320 to rotate relative to the bearing box 210.
[0045] Referring to Figure 4 , Figure 5 and Figure 6 In some embodiments, the side of the through hole 230 away from the support member 100 has a mounting opening 231, and the adjusting mechanism 300 further comprises a blocking member 330 for blocking or opening the mounting opening 231. For example, the blocking member 330 cooperates with the through hole 230 on the cover plate 220, so as to block the mounting opening 231, which can prevent foreign matter from entering the through hole 230, so that the blocking member 330 can effectively protect the adjusting member 320, and can also prevent the through hole 230 from affecting the vacuum degree in the vacuum cavity 211, so as to improve the vacuum adsorption force and the working reliability of the bearing device 10. When it is necessary to operate the adjusting member 320, the blocking member 330 can be removed from the cover plate 220 to open the mounting opening 231 and the entire through hole 230, so that the adjusting wrench can be inserted into the through hole 230 through the mounting opening 231 and contacted with the adjusting member 320, so as to rotate the adjusting member 320 through the adjusting wrench. When the operation of the adjusting member 320 is completed, the blocking member 330 can be cooperated with the through hole 230 again to block the mounting opening 231.
[0046] Referring to Figure 4 , Figure 5 and Figure 6In some embodiments, the adjusting member 320 is provided with a receiving hole 321, which is coaxially arranged with the rotating hole 322 and communicates with the rotating hole 322. The receiving hole 321 is used to cooperate with the adjusting wrench to prevent the adjusting wrench from rotating relative to the adjusting member 320, so that the adjusting wrench applies torque to the adjusting member 320 to drive the adjusting member 320 to rotate. The receiving hole 321 extends to one of the end faces of the adjusting member 320 in the axial direction, so that the receiving hole 321 also communicates with the through hole 230. The rotating hole 322 is arranged at the middle position of the bottom wall of the receiving hole 321, and the edge position of the bottom wall of the receiving hole 321 forms a stepped surface 323, which surrounds the rotating hole 322. Therefore, the receiving hole 321 and the rotating hole 322 can form a stepped hole together. The limiting cap 312 is received in the receiving hole 321, and the limiting cap 312 abuts against the stepped surface 323. In this way, the limiting cap 312 can effectively limit the adjusting member 320 in the axial direction of the locking member 310 to prevent the adjusting member 320 from moving in the axial direction of the locking member 310. The receiving hole 321 is a regular polygon hole, for example, the receiving hole 321 can be a regular hexagonal hole. Of course, the receiving hole 321 can also be a regular triangular hole or a regular quadrilateral hole. In other embodiments, the cross section of the adjusting member 320 can be a regular polygon, which can be inserted into the regular polygon hole of the adjusting wrench, so that the adjusting wrench can drive the adjusting member 320 to rotate.
[0047] Since the number of the adjusting assemblies 301 is at least two, when the bearing surface 221 is inclined relative to the horizontal plane, the adjusting members 320 of some or all of the adjusting assemblies 301 can be adjusted to drive the bearing member 200 and the corresponding local adjusting assemblies 301 to move close to or away from the support member 100, thereby avoiding the inclination of the bearing surface 221 relative to the horizontal plane, and finally making the bearing surface 221 parallel to the horizontal plane, effectively ensuring the flatness of the bearing surface 221, thereby improving the machining precision of the workpiece. During the adjustment of the adjusting member 320, the plug 330 can be first removed from the cover plate 220, then the adjusting wrench can be inserted into the through hole 230 and cooperates with the receiving hole 321, so that the adjusting wrench applies torque to the adjusting member 320 to drive the adjusting member 320 to rotate. The rotational movement of the adjusting member 320 will be converted into the movement of the bearing box 210 away from or close to the support member 100. After the adjustment is completed, the plug 330 can be reinstalled in the mounting opening 231.
[0048] If the mode of unloading the whole cover plate 220 from the bearing box 210 and setting the gasket between the cover plate 220 and the bearing box 210 to ensure the flatness of the bearing surface 221 is adopted, on the one hand, a large number of screws between the cover plate 220 and the bearing box 210 need to be disassembled and assembled, and the disassembly and assembly of the screws are quite cumbersome, thereby affecting the convenience of using the bearing device 10. On the other hand, the cover plate 220 after disassembly will destroy the vacuum degree in the vacuum chamber 211. On the other hand, the operation of setting the gasket is cumbersome, needs to be repeatedly adjusted for many times, and affects the adjustment accuracy of the flatness.
[0049] For the bearing device 10 in the above embodiment, by setting the adjusting mechanism 300, only the blocking piece 330 needs to be disassembled to rotate the adjusting piece 320 by the adjusting wrench to adjust the flatness of the bearing surface 221. On the one hand, the whole cover plate 220 can be avoided to be disassembled, thereby saving a large number of screws to be disassembled and assembled, thereby improving the convenience of using the bearing device 10. On the other hand, the whole cover plate 220 is avoided to be disassembled to affect the vacuum degree of the vacuum chamber 211, and the disassembly of the blocking piece 330 has relatively small influence on the vacuum degree of the vacuum chamber 211 and no influence. On the other hand, the operation of rotating the adjusting piece 320 by the adjusting wrench is relatively simple, which can further improve the convenience of using the bearing device 10, and can also improve the adjustment accuracy of the flatness of the bearing surface 221.
[0050] Referring to Figure 4 , Figure 5 and Figure 6In some embodiments, the adjusting assembly 301 further comprises an abutting member 340, which is arranged on the side of the adjusting member 320 close to the support member 100. One of the abutting member 340 and the adjusting member 320 has a convex spherical surface 341, and the other has a concave spherical surface 324. The convex spherical surface 341 and the concave spherical surface 324 are in contact with each other. The locking member 310 is arranged in the abutting member 340. Since one of the abutting member 340 and the adjusting member 320 has a convex spherical surface 341, and the other has a concave spherical surface 324, the convex spherical surface 341 and the concave spherical surface 324 are in contact with each other. For example, the adjusting member 320 has a concave spherical surface 324, and the abutting member 340 has a convex spherical surface 341. Since the direction of movement of the bearing box 210 during the driving of the adjusting member 320 to move the bearing box 210 close to or away from the support member 100 can be at an angle with the axial direction of the adjusting assembly 301, in other words, the bearing box 210 does not move exactly in the vertical direction, but can move in a direction deviating from the vertical direction by a certain angle, i.e., the bearing box 210 moves obliquely relative to the vertical direction, and the contact between the concave spherical surface 324 and the concave spherical surface 324 can function like a spherical hinge, ensuring that the adjusting member 320 can rotate relative to the abutting member 340 in any direction, thereby effectively avoiding the situation that the adjusting member 320 cannot rotate, and finally effectively ensuring that the adjusting member 320 drives the bearing box 210 to move close to or away from the support member 100, thereby further improving the convenience of use of the bearing device 10 and improving the adjustment accuracy of the flatness of the bearing surface 221.
[0051] Referring to Figure 4 , Figure 5 and Figure 6 In some embodiments, the side of the support member 100 close to the adjusting member 320 is provided with a mounting groove 110, and the abutting member 340 is at least partially located in the mounting groove 110. Therefore, the mounting groove 110 effectively limits the abutting member 340 in the horizontal direction. Also, the abutting member 340 makes full use of the space of the mounting groove 110, thereby realizing the compact design of the bearing device 10 in structure. Of course, the mounting groove 110 can also be omitted, so that the abutting member 340 is directly fixed on the surface of the support member 100.
