In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.
[0037] The present application will be described in detail below in combination with the drawings. As shown in Figures 1 to 7 .
[0038] Embodiment 1: Referring to Figure 1 ; a planar moving mechanism of a laser engraving head, comprising: an X moving mechanism 1, a laser engraving head 6 is connected to the X moving mechanism 1 during use, the X moving mechanism 1 comprises: a horizontally arranged frame body 11, and a horizontal moving block 15 in sliding connection with the frame body 11, the frame body 11 is connected with a horizontal driving mechanism for driving the horizontal moving block 15 to move horizontally;
[0039] The opposite two end faces of the frame body 11 are respectively provided with guide structures, and the two sides of the transverse moving block 15 are respectively provided with moving wheel assemblies capable of moving along the guide structures; the moving wheel assemblies are in abutment with the corresponding guide structures; and at least one side of the moving wheel assemblies is connected with an elastic member for driving itself to be close to the frame body 11.
[0040] Referring to the accompanying drawings Figure 1 At present, the laser engraving machine generally drives the laser engraving head 6 to move in the transverse direction through the X moving mechanism 1. When driving, the transverse moving block 15 is fixedly connected with the laser engraving head 6, the X moving mechanism 1 drives the transverse moving block 15 to move transversely, and drives the laser engraving head 6 to move transversely. Since the engraving head needs to frequently reciprocate in the transverse direction during the working process, the transverse moving block 15 also needs to frequently rub against and move relative to the frame body 11. Exemplarily, in the embodiment, the transverse moving block 15 adopts two moving wheel assemblies to clamp the two end faces of the frame body 11 and abut against the corresponding guide structures. During the relative movement, the moving wheel assemblies are respectively in rolling connection with the corresponding guide structures, so as to reduce the friction coefficient. Secondly, during the use process, even if the rollers of the moving wheel assemblies and / or the guide structures are worn, under the driving of the elastic member, the moving wheel assemblies still remain in close contact with the corresponding guide structures, so as to solve the problem that the transverse moving block 15 and the frame body 11 are shaken during the later movement due to wear, and the engraving precision is low.
[0041] Referring to the accompanying drawings Figure 1 The upper end face and the lower end face of the frame body 11 are respectively provided with guide structures, and the upper side and the lower side of the transverse moving block 15 are respectively provided with moving wheel assemblies capable of moving along the guide structures; the moving wheel assemblies are provided with moving wheels 41, the guide structures include guide grooves 111 arranged on the frame body 11, and the moving wheels 41 respectively extend into the corresponding guide grooves 111.
[0042] Referring to the accompanying drawings Figure 3 Exemplarily, the guide structures are arranged on the upper end face and the lower end face of the frame body 11, and of course, the guide structures can also be arranged on the front end face and the rear end face of the frame body 11. The moving wheels 41 respectively move along the corresponding guide structures. Exemplarily, in the embodiment, the guide structures can adopt the guide grooves 111, that is, the guide grooves 111 are arranged on the upper end face and the lower end face of the frame body 11. The moving wheels 41 located on the upper side and the lower side are respectively connected to the upper end and the lower end of the transverse moving block 15. The moving wheels 41 on the two sides are respectively clamped into the corresponding guide grooves 111, and the moving wheels 41 on the upper side and the lower side form a clamping state with the frame body 11 and are connected with the frame body 11. Under the driving of the transverse driving structure, the transverse moving block 15 moves transversely. Since the moving wheels 41 respectively move along the corresponding guide grooves 111, the transverse moving block 15 forms directional movement, so as to ensure the precision of the transverse movement of the transverse moving block 15.
[0043] In use, the mobile wheel 41 and the end surface of the guide groove 111 will be worn, and due to the elastic force of the elastic member, the mobile wheel 41 will always be in abutting state with the end surface of the guide groove 111, thereby overcoming the deviation caused by wear.
[0044] Secondly, for the convenience of clamping, at least one side of the mobile wheel assembly comprises a rotating arm 43 connected with the transverse moving block 15, and the rotating arm 43 and the transverse moving block 15 are provided with the elastic member, and the outer end of the rotating arm 43 is connected with a rotating shaft 42, and the rotating shaft 42 is sleeved with the mobile wheel 41.
[0045] The mobile wheel assembly is connected with the transverse moving block 15 through the rotating arm 43, and in specific setting, the rotating arm 43 can be connected with a rotating shaft 44, and the transverse moving block 15 is provided with an axle hole matched with the rotating shaft 44, and the rotating shaft 44 is inserted into the axle hole and can rotate relative to the transverse moving block 15; it can be understood that a bearing can be arranged in the axle hole, and the rotating shaft 44 is connected with the bearing, so that the rotating shaft 44 rotates relative to the transverse moving block 15 more flexibly. The elastic member is connected between the rotating arm 43 and the transverse moving block 15, and the elastic member drives the rotating arm 43 to drive the corresponding mobile wheel 41 to move close to the frame body 11; so that the two mobile wheels 41 on both sides form clamping to the frame body 11. In use, when the mobile wheel 41 and the guide structure are worn, the elastic member will always drive the mobile wheel 41 to abut with the guide structure, so as to offset the wear amount and keep the clamping of the two mobile wheels 41 on both sides to the frame body 11.
[0046] Referring to Figure 4 , Figure 5 ; one side of the mobile wheel assembly comprises a main shaft 31 connected with the transverse moving block 15, the main shaft 31 is sleeved with the mobile wheel 41, and the mobile wheel 41 can rotate relative to the transverse moving block 15.
[0047] Referring to the accompanying Figure 4 , Figure 5Exemplarily, the mobile wheel assembly on the upper side in the embodiment adopts the combination of the main shaft 31 and the mobile wheel 41; of course, the mobile wheel assembly on the lower side can also adopt the combination of the main shaft 31 and the mobile wheel 41; the mobile wheel assembly on one side is the fixed wheel structure 3, and the mobile wheel assembly on the other side is the elastic adjusting wheel structure 4, which can make the overall structure more simple; when installing, the mobile wheel assembly of the elastic adjusting wheel structure 4 can be first rotated outwardly to the outer frame body 11, so that the distance between the mobile wheel assemblies on the two sides is greater than the frame body 11, thereby facilitating the movement of the mobile wheels 41 on the two sides to the guide structures on the two sides of the frame body 11 respectively, and then the elastic member is loosened, and the mobile wheels 41 on the two sides form clamping on the frame body 11. The mobile wheel assembly on one side is the combination of the rotating arm 43, the rotating shaft 42 and the mobile wheel 41, and the mobile wheel assembly on the other side is the combination of the main shaft 31 and the mobile wheel 41, and the overall structure is relatively more simple and the cost is lower; it is easy to understand that: after the mobile wheel 41 is sleeved with the main shaft 31, the mobile wheel 41 can be sleeved with the main shaft 31 through the bearing, so that the mobile wheel 41 can rotate relative to the main shaft 31, thereby enabling the lateral moving block 15 to rotate; of course, the mobile wheel 41 can also be directly sleeved with the main shaft 31 to realize the rotation of the mobile wheel 41 relative to the main shaft 31. Secondly, when the main shaft 31 is connected with the lateral moving block 15, the main shaft 31 can be connected with the lateral moving block 15 through the bearing, that is, the lateral moving block 15 is provided with an axle hole, and the axle hole is provided with a bearing connected with the main shaft 31, so that the main shaft 31 can rotate relative to the lateral moving block 15, and then the mobile wheel 41 can rotate relative to the lateral moving block 15.
[0048] Referring to Figure 5 The elastic member includes a torsion spring 45 or / and a tension spring; the inner end of the rotating arm 43 is connected with a rotating shaft 44, the lateral moving block 15 is provided with an axle hole matched with the rotating shaft 44, and the rotating shaft 44 is inserted into the axle hole; the torsion spring 45 is sleeved on the rotating shaft 44, and the two ends of the torsion spring 45 are respectively connected with the lateral moving block 15 and the rotating shaft 44, or / and the two ends of the tension spring are respectively connected with the rotating arm 43 and the lateral moving block 15.
[0049] In order to conveniently drive the mobile wheel 41 to move close to the guide structure on the frame body 11, exemplarily, the structure of the torsion spring 45 is adopted in the embodiment, the rotating arm 43 is driven to rotate by the torsion spring 45, and the mobile wheel 41 connected with the rotating arm 43 is driven to move close to the guide structure; it can be understood that the torsion spring 45 can also be replaced by a tension spring, or the torsion spring 45 and the tension spring are used at the same time, the tension spring drives the rotating arm 43 to have a rotating trend, and the mobile wheel 41 connected with the rotating arm 43 is driven to move close to the guide structure.
[0050] Referring to Figure 3The guide structure comprises a guide groove 111 arranged on the frame body 11, and one end of the moving wheel 41 is inserted into the guide groove 111; the cross section of the guide groove 111 is in a V shape or a trapezoidal shape.
[0051] In order to facilitate the guiding effect, in the embodiment, the guide structure is exemplarily a guide groove 111, and the moving wheel 41 moves along the guide groove 111; when being arranged, in order to avoid the shaking of the moving wheel 41, the moving wheel 41 can be provided in plurality, and in the embodiment, two moving wheels 41 are arranged on each side, and it can be understood that a plurality of moving wheels 41 can be arranged on each side to make the lateral moving block 15 move stably. Secondly, in the use process, in order to ensure that the moving wheel 41 and the guide groove 111 are always in the state of abutment, in the embodiment, the cross section of the guide groove 111 is arranged in a V shape or a trapezoidal shape, and the moving wheel 41 can always abut against the two sides of the guide groove 111, even if the two sides of the moving wheel 41 and the guide groove 111 are worn.
[0052] Referring to Figure 6 , Figure 7 The guide structure comprises a guide rod 114 arranged on the frame body 11, and the middle part of the side surface of the moving wheel 41 is recessed to form an annular groove 33 matched with the guide rod 114.
[0053] In the use process, in order to reduce the wear, a material with high hardness and wear resistance is generally used. If the frame body 11 directly abuts against the moving wheel 41 and friction occurs, in order to reduce the wear, the material of the whole frame body 11 needs to be replaced, which will inevitably increase the cost, and the proportion of the wear-resistant part used is small. Therefore, in order to reduce the cost and increase the wear resistance of the contact part, in the embodiment, the structure of arranging the guide rod 114 is exemplarily adopted, the guide rod 114 can be made of a material with high hardness and wear resistance, or a wear-resistant layer can be formed on the side surface of the guide rod 114 by plating, or only the wear-resistant layer can be electroplated on the exposed side surface of the guide rod 114. Correspondingly, the moving wheel 41 is provided with a recessed structure in the middle part of the side surface, the guide rod 114 passes through the annular groove 33 in the side surface of the moving wheel 41, and the moving wheel 41 rotates along the guide rod 114 during movement.
[0054] Secondly, it can be understood that, in order to facilitate the arrangement of the guide rod 114, a concave groove 113 can be arranged on the frame body 11, and the lower half of the guide rod 114 is arranged in the concave groove 113. Of course, the guide rod 114 can be fixed by other ways, such as welding, and the guide structure can also be a guide block with a V-shaped groove or a trapezoidal groove arranged on the surface, and the guide block is fixed to the frame body 11 instead of the guide rod 114. The length of the guide rod 114 is less than the length of the frame body 11.
[0055] Referring to Figure 1 , Figure 2The lateral drive mechanism includes a drive member 14 disposed on one side of the frame 11 and a drive pulley 18 drivenly connected to the drive member 14. The drive member 14 can drive the drive pulley 18 to rotate. A driven pulley 13 is disposed on the other side of the frame 11. The drive pulley 18 is connected to the driven pulley 13 through a belt. The belt is connected to the lateral moving block 15. When the drive member 14 drives the drive pulley 18 to rotate, the belt moves and drives the lateral moving block 15 to move laterally.
[0056] See appendix Figure 1 , Figure 2 To facilitate the lateral movement of the transverse moving block 15, a belt drive mechanism is used for the lateral drive mechanism. The driving component 14 can be a servo motor. The servo motor's shaft 42 is connected to the drive pulley 18, or to the drive pulley 18 via a transmission mechanism 16. The servo motor drives the drive pulley 18 to rotate and moves the belt. During this movement, the belt drives the lateral moving block 15 to move laterally. Figure 1 As shown, exemplarily, a main auxiliary frame 17 and a secondary auxiliary frame 12 are respectively connected to both sides of the frame 11. The main auxiliary frame 17 is fixedly connected to the servo motor. It can be understood that the servo motor can be directly shaft-connected to the drive pulley 18 and directly drive the drive pulley 18 to rotate. In this embodiment, a transmission mechanism 16 is used, which includes a first intermediate component 161 connected to the servo motor and a second intermediate component 162 connected to the drive pulley 18. The first intermediate component 161 and the second intermediate component 162 are connected. The transmission mechanism 16 can be a gear transmission mechanism, a belt transmission mechanism, a chain transmission mechanism, etc. As shown in the figure, exemplarily, the transmission mechanism uses a belt transmission mechanism, and both the first intermediate component 161 and the second intermediate component 162 are pulleys. It should also be noted that the belt in this application includes synchronous belts and other belts; the pulleys include synchronous pulleys and other pulleys.
[0057] See Figure 3 , Figure 6 The frame 11 is hollow in the middle to form an inner space 115 for the belt to pass through. The end face of the frame 11 near the transverse moving block 15 is recessed to form an outer space 112 for the belt to pass through. The two sides of the transverse moving block 15 are respectively connected to clamping block assemblies 5 for clamping the belt. The clamping block assembly 5 includes a main clamping block 53, which is connected to the side of the transverse moving block 15 through a connector 54. The main clamping block 53 has a notch in the middle of the side near the frame 11 for the belt to pass through. A secondary clamping block 52 is provided in the notch. The secondary clamping block 52 is connected to the main clamping block 53 and clamps the belt.
[0058] In the working process, the belt needs to be protected from external interference, in the embodiment, the frame body 11 is set as a hollow structure, the inside of the frame body 11 forms an inner space 115 and is used for the belt to pass through; the middle part of one of the outer end faces of the frame body 11 is concave to form an outer space 112, which is also used for the belt to pass through; the inner space 115 and the outer space 112 are combined to protect the belt and reduce the risk of belt interference. Secondly, in order to facilitate the connection of the belt and the transverse moving block 15, in the embodiment, the clamping block assembly 5 is exemplarily used, the clamping block assembly 5 includes a main clamping block 53 and a secondary clamping block 52, the main clamping block 53 is connected with the transverse moving block 15 through a connecting piece, the connecting piece can adopt a transverse bolt and the like; by adopting such a structure, the clamping block assembly 5 can be conveniently disassembled and replaced with different clamping block assemblies 5. The spacing between the clamping block assembly 5 and the transverse moving block 15 can be adjusted by rotating the transverse bolt; when adjusting the spacing, the spacing between the two clamping block assemblies 5 can also be adjusted, thereby adjusting the tension of the belt. Secondly, the transverse bolt is connected with two adjacent fixed nuts, one of which abuts against the transverse moving block 15 and is used to determine the position of the transverse bolt connected with the transverse moving block 15, and the other fixed nut abuts against the main clamping block 53, the fixed nut and the head of the transverse bolt clamp the main clamping block 53 to determine the position of the main clamping block 53. In the embodiment, the main clamping block 53 and the secondary clamping block 52 are exemplarily used to clamp the belt, and of course other clamping structures can also be used.
[0059] Preferably, the two sides of the X moving mechanism 1 are respectively connected with Y moving mechanisms 2, the X moving mechanism 1 drives the laser engraving head 6 to move transversely, and the two Y moving mechanisms 2 synchronously drive the X moving mechanism 1 to move longitudinally.
