Detailed implementation manners

[0028] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many other different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] The following combines Figures 1-5 To further elaborate in detail on the processing table and the laser processing equipment involved in the present invention.

[0032] In an embodiment of a processing table, the processing table is used for laser processing. The processing table includes a plurality of table bodies 1, a power meter 2, and a driving assembly 3. The table body 1 is used to support the workpiece. The power meter 2 is capable of sliding relative to the plurality of table bodies 1. The output end of the driving assembly 3 is connected to the power meter 2 and is used to drive the power meter 2 to linearly move so that the power meter 2 can reciprocate between the plurality of table bodies 1.

[0033] In this embodiment, by setting the power meter 2 to be capable of sliding relative to the table body 1 and the power meter 2 performs linear movement under the drive of the driving assembly 3, the original equipment stroke can be unchanged, and it can be adapted to the multi-axis simultaneous processing method, solving the technical problem that the multi-axis simultaneous processing in the existing laser processing equipment is not adapted to the fixed power meter 2.

[0034] For the existing equipment to process, its beam energy emits from the light source and passes through an optical path system several meters long. By setting the power meter 2, the on-line measurement requirement of the beam energy of the machine tool equipment can be met. To cope with the multi-axis multi-beam equipment, a single fixed power meter 2 cannot meet the energy measurement of multiple axes within the effective operating stroke of the machine tool equipment. In this embodiment, the power meter 2 is designed to be movable. Thus, within the effective stroke range of the workbench, the power meter 2 is arranged on the table body 1, and through the movement of the driving assembly, the power meter 2 is driven to move secondly. This method does not occupy the workbench stroke and the processing space, and greatly reduces the structural cost of the machine tool.

[0035] It can be understood that the power meter 2 is a measurement means for testing the processing beam energy to ensure the accuracy of the processing energy. When multi-axis multi-beam simultaneous processing is performed, the fixed power meter 2 cannot meet the energy measurement of multiple axes, while the power meter 2 in this embodiment is movable, so that the energy of each axis can be measured.

[0036] In an embodiment of a processing table, the table body 1 is provided with opposite first side 11 and second side 12. The first side 11 is used to support the workpiece, and the driving assembly 3 is installed on the second side 12.

[0037] In this embodiment, by installing the driving assembly 3 on the second side, the driving assembly 3 can be combined with the table body 1, and at the same time, the power meter 2 can also be combined with the table body 1. With such a setting, it can be further convenient for the power meter 2 to follow the movement of the table body 1 and then perform a secondary movement relative to the table body 1.

[0038] In an embodiment of a processing table, the driving assembly 3 includes a driving member 31 and a guiding member 32. The power meter 2 is slidably installed on the guiding member 32. The output end of the driving member 31 is connected to the power meter 2 and is used to drive the power meter 2 to slide on the guiding member 32. The guiding member 32 is used to guide the movement of the power meter 2.

[0039] In this embodiment, by providing the guiding member 32, the movement of the power meter 2 can be guided, ensuring the movement accuracy of the power meter 2 and stable operation.

[0040] Specifically, the guiding member 32 may include a slide rail and a slider, and the power meter 2 is installed on the slider. It can also be a combination of a chute and a slider. The driving member 31 can be a rodless cylinder.

[0041] It can be understood that the driving assembly 3 is arranged on the second side 12, which can reduce the occupied area and will not occupy the processing space.

[0042] In addition, two limit blocks can be added. The two limit blocks are installed on the slide rail at intervals to limit the stroke of the power meter 2.

[0043] In an embodiment of the processing table, the power meter 2 is arranged at one end of a plurality of table bodies 1.

[0044] In this embodiment, two table bodies can be abutted together or have a small gap to form a large plate. The power meter 2 is arranged at one end of a plurality of table bodies 1. As shown in the figure, the two table bodies 1 are abutted together, and the power meter 2 is arranged at the end and reciprocates along the X-axis.

[0045] In an embodiment of the processing table, the driving assembly 3 straddles at least part of each table body 1. Specifically, the driving assembly 3 can be a rodless cylinder module. To enable the power meter 2 to reciprocate between a plurality of table bodies 1, the driving stroke of the driving assembly 3 needs to straddle each table body 1. When the number of table bodies 1 is two, the stroke of the driving assembly 3 can be part of the two table bodies 1, and when the number of table bodies 1 is three, the stroke of the driving assembly 3 needs to completely straddle the middle table body 1.

[0046] Combined with the previous embodiment, it can be understood that the extension length of the guiding member 32 straddles at least part of the table body 1. For example, if the guiding member 32 is a slide rail, at least part of it needs to extend to the positions corresponding to each table body 1.

[0047] In an embodiment of the processing table, the processing table further includes a fixing assembly 7, and the fixing assembly 7 is simultaneously connected to the second sides 12 of two table bodies 1.

[0048] In this embodiment, by providing two table bodies 1, two workpieces can be processed simultaneously, improving the processing effect. Specifically, the fixing assembly 7 can be a frame structure. One part can be fixed to the second side 12 of one table body 1 by bolts, and the other part can be fixed to the second side 12 of the other table body 1 by bolts in the same way.

[0049] In an embodiment of the processing table, the processing table further includes a plurality of pin sets 4. Each pin set 4 is arranged at the edge of the first side 11 and forms a positioning pattern for the manipulator to position and calibrate the position.

[0050] In this embodiment, a positioning pattern is formed by the pin group 4, which can facilitate the positioning basis for the robot to load and unload workpieces, thereby ensuring the consistent position of the workpieces during batch loading and unloading and improving the processing effect. Specifically, the number of the pin groups 4 can be two, each pin group 4 can include two pins, the two pin groups 4 can be arranged at the corners of the table body 1, and the pin connections within each pin group 4 can form an included angle, and forms such as crossing are also possible.

[0051] In a laser processing system, a galvanometer is often used, for example, to change the direction of the laser so as to adjust the processing position of the laser. Therefore, the galvanometer needs to be calibrated during use.

[0052] In an embodiment of the processing table, the processing table further includes a calibration element 5 and a pressing assembly 6. The calibration element 5 is installed on the first side 11, and the calibration element 5 is used to calibrate the galvanometer. The processing table includes a pressing assembly 6. The pressing assembly 6 is installed on the first side 11 and is used to press the calibration element 5 against the first side 11.

[0053] In this embodiment, by providing the calibration element 5, it is convenient to calibrate the galvanometer. Specifically, the calibration element 5 can be an acrylic plate. The galvanometer emits light to drill holes in the calibration plate, and then a CCD is used to capture, and its accuracy is corrected through a feedback system.

[0054] In addition, it can be understood first that the calibration element 5 is laser processed during the calibration process. Therefore, the calibration element 5 needs to be replaced regularly. In order to facilitate the replacement of the calibration element 5, in this embodiment, the pressing assembly 6 is used to simply fix the calibration element 5 in a pressed manner, which can ensure that the position of the calibration element 5 does not shift during the calibration process.

[0055] Furthermore, in order to ensure the position accuracy of the calibration element 5 during the replacement of the calibration element 5, the table body 1 and the calibration element 5 can be positioned by positioning pins.

[0056] In an embodiment of the processing table, the pressing assembly 6 includes a stud 61 and a pressing piece 62. The pressing piece 62 is connected to the stud 61. A threaded hole capable of being threadedly engaged with the stud 61 is formed on the table body 1. When the stud 61 rotates with the threaded hole, the pressing piece 62 can be driven to approach or move away from the calibration element 5.

[0057] In this embodiment, the spinning pressing method can facilitate the operation of the staff and can well press the calibration element 5.

[0058] Combined with the previous embodiments, the number of the calibration elements 5 can be multiple, and they are arranged on each table body 1 in a one-to-one correspondence.

[0059] In an embodiment of a processing table, the table body 1 is provided with air permeation holes 13 extending from the first side 11 to the second side 12. The processing table further includes a negative pressure assembly which is communicated with the air permeation holes 13 so as to be able to adsorb a workpiece on the first side 11.

[0060] In this embodiment, by providing the air permeation holes 13 and the negative pressure assembly, an adsorption effect can be generated, and the workpiece will be adsorbed and fixed after being placed on the first side 11.

[0061] Further, in combination with the previous embodiment, the calibration element 5 can also be adsorbed and fixed by the negative pressure assembly. Preferably, the air permeation holes 13 are evenly distributed on the table body 1, and the negative pressure assembly can be externally disposed on the table body 1 and communicated with the negative pressure assembly by installing an air pipe 14 on the second side 12.

[0062] In an embodiment of a processing table, the power meter 2 and the calibration element 5 can be arranged at the same end of the table body 1. Specifically, they can be both arranged at the rear, and the front can be used for staff to operate, avoiding occupying the front space. Placing the calibration element 5 at the rear makes it closer to the galvanometer, and the movement of the power meter 2 can also reduce the blockage of the movement stroke of other components.

[0063] The present utility model also relates to a laser processing device, including the processing table in the previous embodiment.

[0064] By applying the processing table in the previous embodiment, there is a movable power meter 2, so that it can facilitate matching the measurement requirements of multi-axis simultaneous processing, and solves the technical problem that the multi-axis simultaneous processing in the existing laser processing device is not compatible with the fixed power meter 2.

[0065] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0066] The above embodiments only express several implementation manners of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
