[0031] The following refers to Figures 1 to 4 to describe in detail the base platform of the first aspect of the present utility model.

[0032] Refer to Figures 1 to 3 , the base platform according to some embodiments of the present utility model includes a base 100, a cross beam 200 and a base 300; the cross beam 200 is used for installing a laser module; both ends of the cross beam 200 in its own length direction are respectively carried on the base 100 through a base 300, a processing area 101 is formed between the two bases 300, and a relief groove 310 is opened on one side of the base 300 close to the processing area 101. The relief groove 310 extends along the width direction of the cross beam 200 and is used for accommodating the edge of the bearing platform. The relief groove 310 has a first groove edge 311a located above and a second groove edge 313a located below. In the horizontal projection plane, the orthographic projections of the two second groove edges 313a are both located in the area between the orthographic projections of the two first groove edges 311a.

[0033] For example, as Figures 1 to 3As shown, the base platform includes a base 100, a cross beam 200 and two bases 300. The cross beam 200 extends in the left - right direction. The left and right ends of the cross beam 200 are respectively carried on the base 100 through the two bases 300. A processing area 101 is formed between the two bases 300. Among the two bases 300, the base 300 on the left is the first base 300A, and the base 300 on the right is the second base 300B. Avoidance grooves 310 are provided on the right side of the first base 300A and the left side of the second base 300B. The avoidance groove 310 on the first base 300A is the first avoidance groove, and the avoidance groove 310 on the second base 300B is the second avoidance groove. The first avoidance groove opens to the right and extends in the front - back direction. The second avoidance groove opens to the left and extends in the front - back direction. The upper edge of the avoidance groove 310 is the first edge 311a, and the lower edge of the avoidance groove 310 is the second edge 313a. In the first avoidance groove, in the horizontal projection plane, the orthographic projection of the first edge 311a is located on the left side of the orthographic projection of the second edge 313a. In the second avoidance groove, in the horizontal projection plane, the orthographic projection of the first edge 311a is located on the right side of the orthographic projection of the second edge 313a.

[0034] It should be noted that when the base platform of this embodiment is applied to a laser processing device, a laser module is installed on the cross beam 200, and a loading platform is slidably installed on the base 100. When the laser processing device is working, the loading platform can slide forward relative to the base 100 to leave the processing area 101. At this time, the workpiece can be loaded on the loading platform. Then, the loading platform can slide backward relative to the base 100 to drive the workpiece into the processing area 101. At this time, the laser module on the cross beam 200 can perform laser processing on the workpiece on the loading platform.

[0035] It can be understood that since avoidance grooves 310 are provided on the sides of the two bases 300 close to each other, after the loading platform slides into the processing area 101, the left and right edges of the loading platform can be respectively received in the avoidance grooves 310 of the two bases 300. Thus, on the premise that there is no interference between the loading platform and the bases 300, the distance between the two bases 300 can be set closer, the length of the cross beam 200 can be set shorter, and the overall size of the base 100 can also be set smaller. Furthermore, the overall structure of the base platform of this embodiment can be set smaller, reducing the overall occupied space of the base platform of this embodiment.

[0036] In some embodiments of the present utility model, refer to Figure 3, the base 300 includes a first bearing portion 301, a second bearing portion 302, and a third bearing portion 303 that are connected in sequence from top to bottom. The second bearing portion 302 is connected to one end of the first bearing portion 301 away from the processing area 101, and the second bearing portion 302 is connected to one end of the third bearing portion 303 away from the processing area 101, so that the first bearing portion 301, the second bearing portion 302, and the third bearing portion 303 jointly define an avoidance groove 310; in the length direction of the cross beam 200, the size of the third bearing portion 303 is larger than the size of the first bearing portion 301. At the junction of the end face of the first bearing portion 301 near the processing area 101 and the lower end face of the first bearing portion 301, a first groove edge 311a is formed. At the junction of the end face of the third bearing portion 303 near the processing area 101 and the upper end face of the third bearing portion 303, a second groove edge 313a is formed.

[0037] It can be understood that since the size of the third bearing portion 303 in the length direction of the cross beam 200 is larger than the size of the first bearing portion 301 in the length direction of the cross beam 200, the stability of the base 300 can be improved, and further, the stability of the cross beam 200 can be improved.

[0038] Specifically, referring to Figure 3 , for the first base 300A on the left side, the upper end of the second bearing portion 302 is connected to the lower left end of the first bearing portion 301, and the lower end of the second bearing portion 302 is connected to the upper left end of the third bearing portion 303. At this time, the right half of the lower end face of the first bearing portion 301, the right end face of the second bearing portion 302, and the right half of the upper end face of the third bearing portion 303 jointly define a first avoidance groove. At the junction of the lower end face of the second bearing portion 302 and the right end face of the first bearing portion 301, a first groove edge 311a is formed. At the junction of the upper end face of the second bearing portion 302 and the right end face of the third bearing portion 303, a second groove edge 313a is formed, and the second groove edge 313a is located at the lower right side of the first groove edge 311a.

[0039] Similarly, for the second base 300B on the right side, the upper end of the second bearing portion 302 is connected to the lower right end of the first bearing portion 301, and the lower end of the second bearing portion 302 is connected to the upper right end of the third bearing portion 303. At this time, the lower left end face of the first bearing portion 301, the left end face of the second bearing portion 302, and the upper left end face of the third bearing portion 303 jointly define a second avoidance groove. At the junction of the lower end face of the second bearing portion 302 and the left end face of the first bearing portion 301, a first groove edge 311a is formed. At the junction of the upper end face of the second bearing portion 302 and the left end face of the third bearing portion 303, a second groove edge 313a is formed, and the second groove edge 313a is located at the lower left side of the first groove edge 311a.

[0040] It should be noted that in the laser processing equipment, the bearing platform is an inverted trapezoid with a wider upper part and a narrower lower part.

[0041] In order to enable the avoidance groove 310 to adapt to the overall shape of the bearing platform, in some embodiments of the present invention, referring to Figure 3 and Figure 4 , the avoidance groove 310 includes a first groove wall 311, a second groove wall 312 and a third groove wall 313 that are smoothly connected in sequence. The edge of the first groove wall 311 away from the second groove wall 312 forms a first groove edge 311a, and the edge of the third groove wall 313 away from the second groove wall 312 forms a second groove edge 313a, and the third groove wall 313 is inclined downward.

[0042] For example, as Figure 3 shown, for the first base 300A, the right half of the lower end surface of the first bearing portion 301 constitutes the first groove wall 311, the right end surface of the second bearing portion 302 constitutes the second groove wall 312, and the right half of the upper end surface of the third bearing portion 303 constitutes the third groove wall 313. The right half of the upper end surface of the third bearing portion 303 is inclined downward to the right.

[0043] It can be understood that for the first base 300A, the right half of the upper end surface of the third bearing portion 303 is inclined downward to the right. On the one hand, it can make the inclination direction of the third groove wall 313 adapt to the inclination direction of the left edge of the bearing platform. On the other hand, it can make the size of the third bearing portion 303 in the horizontal direction gradually increase from top to bottom, so as to improve the bearing capacity of the third bearing portion 303, thereby improving the bearing capacity of the entire first base 300A.

[0044] It can be understood that, similarly, for the second base 300B, the left half of the upper end surface of the third bearing portion 303 is inclined downward to the left. On the one hand, it can make the inclination direction of the third groove wall 313 adapt to the inclination direction of the right edge of the bearing platform. On the other hand, it can make the size of the third bearing portion 303 in the horizontal direction gradually increase from top to bottom, so as to improve the bearing capacity of the third bearing portion 303, thereby improving the bearing capacity of the entire second base 300B.

[0045] In some embodiments of the present invention, the base 300 is provided with a hollow structure.

[0046] It can be understood that by providing a hollow structure on the base 300, while ensuring that the base 300 has the required strength, the weight of the entire base 300 can be reduced, and the material cost of manufacturing the entire base 300 can be reduced.

[0047] In a further embodiment of the present invention, referring to Figure 2 , the hollow structure includes a plurality of hollow holes 320 that are spaced apart along the width direction of the cross beam 200, and the hollow holes 320 penetrate through the base 300 along the length direction of the cross beam 200.

[0048] For example, as Figure 2 shown, the length direction of the cross beam 200 is the left - right direction, and the width direction of the cross beam 200 is the front - back direction; the hollow structure includes a plurality of hollow holes 320 spaced apart in the front - back direction, and each hollow hole 320 penetrates the base 300 in the left - right direction.

[0049] In some other embodiments of the present utility model, the hollow structure may also include a single hollow hole 320. At this time, the hollow hole 320 penetrates the base 300 in the left - right direction.

[0050] In some embodiments of the present utility model, the hollow hole 320 communicates with the avoidance groove 310.

[0051] It can be understood that the avoidance groove 310 is provided in the middle of the entire base 300. Connecting the hollow hole 320 with the avoidance groove 310 can, on the one hand, enable the hollow hole 320 to be arranged in the middle of the base 300 to ensure that the entire base 300 has sufficient strength, and on the other hand, can reduce the difficulty in the casting and molding process of the base 300.

[0052] In some embodiments of the present utility model, referring to Figure 4 , a ring - shaped reinforcing rib 321 is provided on the hole wall of the hollow hole 320.

[0053] It can be understood that by providing a ring - shaped reinforcing rib 321 on the hole wall of the hollow hole 320, the difficulty of deformation of the hole wall of the hollow hole 320 can be increased, thereby improving the overall strength of the base 300.

[0054] It should be noted that a laser module needs to be installed on the cross beam 200. The laser module includes a vertical adjustment structure and a laser generation structure. The laser generation structure is used to emit laser for laser processing of workpieces. The vertical adjustment structure is connected to the laser generation structure and is used to adjust the position of the laser generation structure in the vertical direction.

[0055] In some embodiments of the present utility model, referring to Figure 1 , a vertically extending receiving groove 210 is provided on the cross beam 200, and the receiving groove 210 is used to receive the vertical adjustment structure of the laser module.

[0056] It can be understood that by providing a vertically extending receiving groove 210 on the cross beam 200, when the base platform of this embodiment is applied to a laser processing device, the vertical adjustment structure of the laser module can be partially received in the receiving groove 210, so as to reduce the volume of the entire laser processing device.

[0057] In a further embodiment of the present utility model, referring to Figure 1The receiving groove 210 includes a first section 211, a second section 212 and a third section 213 which are connected in sequence along the vertical direction. The depth of the second section 212 is smaller than that of the first section 211 and the third section 213. The first section 211 is used to accommodate the driver of the vertical adjustment structure, the second section 212 is used to accommodate the screw rod of the vertical adjustment structure, and the third section 213 is used to accommodate the oil receiving pan of the vertical adjustment structure.

[0058] It should be noted that the cross-sectional dimension of the screw rod is smaller than the cross-sectional dimension of the driver, and the cross-sectional dimension of the screw rod is smaller than the cross-sectional dimension of the oil pan.

[0059] It is understandable that by setting the depth of the second section 212 to be smaller than the depth of the first section 211 and the depth of the third section 213 , the structural strength of the beam 200 can be improved while ensuring that the screw rod can be normally accommodated in the second section 212 .

[0060] It should be noted that when the base platform of the present application is used in laser processing equipment, a bearing platform needs to be installed on the base 100, and a drag chain for transmission needs to be set on the base 100, and the driving structure is connected to the bearing platform through the drag chain, so that the driving structure can smoothly drive the bearing platform to slide horizontally relative to the base 100. However, the setting of the drag chain makes the space occupied by the entire laser processing equipment larger.

[0061] Based on the above problems, in some embodiments of the present invention, reference Figure 1 A drag chain installation groove 110 extending along the width direction of the beam 200 is provided on the base 100 , and a portion of the drag chain installation groove 110 is located in the processing area 101 .

[0062] It is understandable that by providing a drag chain installation groove 110 on the base 100, when the base platform of this embodiment is applied to laser processing equipment, the drag chain can be accommodated in the drag chain installation groove 110 to reduce the overall occupied space of the laser processing equipment.

[0063] The laser processing equipment provided in accordance with the embodiment of the second aspect of the utility model includes the base platform provided in the embodiment of the first aspect of the utility model; the laser processing equipment also includes a laser module and a carrying platform, the laser module is arranged on the beam 200, and the carrying platform can be slidably arranged on the base 100, and under the action of external force, the carrying platform can slide into or out of the processing area 101.

[0064] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
