[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The purpose of the present invention is to provide a floating coding head and a laser coding device including the same, so as to solve the problems existing in the above-mentioned prior art, and realize the coding operation of products to be coded with different sizes without debugging the position of the execution device, thereby improving the coding efficiency.

[0029] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0030] The present invention provides a floating coding head, as Figures 1 to 3As shown, it includes a capping head assembly 11 and a floating assembly 12. Among them, the floating assembly 12 includes a fixed connection plate 121 and a floating connection plate 122, and the floating connection plate 122 can reciprocate relative to the fixed connection plate 121; the fixed connection plate 121 is used to connect to the execution end of the execution device 2, and the floating connection plate 122 is connected to one end of the capping head assembly 11. The product to be capped is placed on the workbench 6, and the other end of the capping head assembly 11 is used to abut against the surface of the product to be capped during capping. By abutting the capping head assembly 11 against the surface of the product to be capped, the relative position between the capping head assembly 11 and the surface of the product to be capped remains unchanged, and the focal length of laser capping does not change with the size of the product to be capped, that is, the focal length of laser capping is always within an appropriate range.

[0031] In the present invention, the distance between the floating connection plate 122 and the fixed connection plate 121 can be adaptively adjusted according to the size change of the product to be capped, and when capping products of different sizes, the position of the fixed connection plate 121 can remain unchanged, or it can be understood that the relative position between the fixed connection plate 121 and the workbench 6 can remain unchanged; that is, when capping workpieces of different sizes, the execution device 2 and the fixed connection plate 121 are both in the same position, and there is no need to debug the execution device 2. By changing the distance between the floating connection plate 122 and the fixed connection plate 122, capping operations for products to be capped of different sizes can be adapted within a certain range, without adjusting the position of the execution device 2 to adjust the capping focal length, so as to save the movement time of the execution device 2 and reduce the manual debugging time and difficulty, and improve the capping efficiency.

[0032] In a specific embodiment, when the present invention caps products with the same length dimension but different thicknesses, the execution device 2, such as a six-axis robot, presses the floating capping head 1 bracket against the product to be capped, without adjusting the position of the robot to adapt to the capping focal length; the distance between the floating connection plate 122 and the fixed connection plate 121 is adaptively adjusted according to the thickness dimension change of the product to be capped. At this time, the positions of the fixed connection plate 121 and the execution end of the execution device 2 can both remain unchanged, so as to save the debugging time and movement time of the execution device 2 and improve the capping efficiency. For example, if the length, width, and height of the previous capping product were 100 cm × 100 cm × 5 cm, and now the length, width, and height of the capping product are 100 cm × 100 cm × 20 cm, at this time, there is no need to adjust the height position of the robot to adapt to the capping focal length. The robot still moves the capping head assembly 11 to the previous height position of 100 cm × 100 cm × 5 cm, and the floating assembly 12 automatically adjusts the focal length of the capping head assembly 11 to complete capping.

[0033] And it can be understood that the distance between the floating connection plate 122 and the fixed connection plate 121 of the present invention can also be adaptively adjusted according to other dimensions of the product to be coded, such as the width dimension. The present invention does not make specific limitations on this.

[0034] In some embodiments, a camera assembly 13 is further included. The camera assembly 13 is located on one side of the coding head assembly 11 and is connected to the coding head assembly 11. The camera assembly 13 is used to take pictures of the product to be coded for visual positioning before coding, and the camera assembly 13 is also used to take pictures and identify the coding area of the product to be coded after coding is completed.

[0035] It should be noted that the present invention can drive the coding head assembly 11 to move to the corresponding position for coding by taking pictures of the product to be coded by the camera assembly 13 for visual positioning before coding. And by directly identifying the coding area after coding is completed, it can not only judge the coding effect, but also input the identified coding content into the system, which is convenient for docking with users. When the system judges that the coding effect is not appropriate, the system can send an instruction to control secondary coding, and then the camera assembly 13 is used to identify and judge the coding effect again.

[0036] In some embodiments, as Figure 2 shown, the floating assembly 12 further includes side plates 123, sliding connection blocks 124, guide posts 125, elastic members 126 and support plates 127. The two side plates 123 are respectively vertically connected to the fixed connection plate 121. The sliding connection blocks 124 are located below the fixed connection plate 121 and are arranged at intervals relative to each other. The support plate 127 is located between the sliding connection blocks 124 and the fixed connection plate 121. The sliding connection blocks 124 are located between the two side plates 123 and are fixedly connected to the side plates 123.

[0037] One ends of a plurality of guide posts 125 all pass through the sliding connection blocks 124 and are fixedly connected to the support plates 127. The other ends of the plurality of guide posts 125 are all fixedly connected to the floating connection plate 122. Each guide post 125 is sleeved with an elastic member 126. The plurality of guide posts 125 are slidably connected to the sliding connection blocks 124, and the relative sliding of the plurality of guide posts 125 with respect to the sliding connection blocks 124 can adjust the distance between the floating connection plate 122 and the fixed connection plate 121.

[0038] It should be noted that the elastic member 126 of the present invention is a spring. When the size of the product to be coded changes, the position of the abutting end of the coding head assembly 11 and the product to be coded changes. At this time, the plurality of guide posts 125 can slide relative to the sliding connection blocks 124. The fixed connection block 122 is in the same position driven by the actuating device 2, and the plurality of guide posts 125 drive the floating connection plate 122 to move to adjust the distance between the floating connection plate 122 and the fixed connection plate 121.

[0039] In some embodiments, the two ends of the elastic member 126 respectively abut against the sliding connection block 124 and the floating connection plate 122. When the plurality of guide posts 125 move upward relative to the sliding connection block 124, the elastic member 126 can be compressed, and the elastic force of the elastic member 126 can cause the plurality of guide posts 125 to move downward relative to the sliding connection block 124.

[0040] The present invention can also abut the two ends of the elastic member 126 against the sliding connection block 124 and the support plate 127 respectively.

[0041] In some embodiments, the floating assembly 12 further includes linear bearings; a plurality of through holes are provided on the sliding connection block 124, and linear bearings are installed in each through hole. The plurality of guide posts 125 are respectively inserted through the plurality of through holes, and the plurality of guide posts 125 are slidably connected to the sliding connection block 124 through the linear bearings.

[0042] In some embodiments, refer to Figure 2 and Figure 3 As shown, the coder head assembly 11 includes a laser assembly 111, a first connection block 112, an optical path conduction assembly 113, and a protective cover 114; wherein, the laser assembly 111 is connected to the floating connection plate 122, both ends of the first connection block 112 are respectively connected to the laser assembly 111 and the optical path conduction assembly 113, a through hole for the beam to pass through is provided on the first connection block 112, and the beam emitted by the laser assembly 111 can pass through the through hole and enter the optical path conduction assembly 113; one end of the protective cover 114 is connected to the optical path conduction assembly 113, and the other end is used to abut against the surface of the product to be coded during coding.

[0043] In some embodiments, as Figure 3 shown, the camera assembly 13 includes a second connection block 131, a camera fixing plate 132, a light source fixing plate 133, a camera 134, and a light source module 135; wherein, the second connection block 131 is fixedly connected to the first connection block 112; the camera fixing plate 132 is vertically connected to the second connection block 131, and the camera 134 is fixedly connected to the camera fixing plate 132; the light source fixing plate 133 is vertically connected to the bottom end of the camera fixing plate 132, and the light source module 135 is fixedly connected to the light source fixing plate 133, and the light source module 135 is located below the camera 134. The light source module 135 of the present invention is used to provide light source output when the camera 134 takes pictures.

[0044] In a specific embodiment, the camera fixing plate 132 includes a first fixing plate 1321 and a second fixing plate 1322. One end of the first fixing plate 1321 is perpendicularly connected to the second connecting block 131. The second fixing plate 1322 is disposed on the side of the first fixing plate 1321 away from the capping head assembly 11. The camera 134 is fixedly connected to the second fixing plate 1322. The light source fixing plate 133 is perpendicularly connected to the bottom end of the first fixing plate 1321, and the light source module 135 is connected to the bottom surface of the light source fixing plate 133.

[0045] In some embodiments, continue to refer to Figure 3 , the laser assembly 111 includes a capping head connecting plate 1111, a laser isolator head, and an isolator head fixing block. Among them, the capping head connecting plate 111 is fixedly connected to the floating connecting plate 122. The isolator head fixing block is perpendicularly connected to the capping head connecting plate 1111. One end of the laser isolator head is fixedly connected to the isolator head fixing block, and the other end is disposed opposite to the first connecting block 112. And the light beam emitted by the laser isolator head can pass through the through hole on the first connecting block 112.

[0046] In some embodiments, the optical path conduction assembly 113 includes a galvanometer assembly 1131 and a field lens 1132. The light beam emitted by the laser isolator head can sequentially pass through the galvanometer assembly 1131 and the field lens 1132 after passing through the through hole, and the galvanometer assembly 1131 can perform yaw adjustment on the light beam to code the position.

[0047] In the specific coding size range of the present invention, the robot can complete coding without moving, through the vision of the camera assembly 13 and the yaw of the galvanometer assembly 1131 of the capping head assembly 11. This can save the robot movement time, reduce the manual debugging time and difficulty, and complete marking faster.

[0048] The embodiment of the present invention also provides a laser coding device, as Figure 1 shown, including the above-mentioned floating capping head 1, execution device 2, laser coding machine main body 3, main control box 4, fume purifier 5, and workbench 6. Among them, the workpiece to be coded is placed on the workbench 6. The execution device 2 is used to drive the floating capping head 1 to move. The fume purifier 5 is used to process the fumes generated during coding, that is, the fume purifier 5 can process the fumes generated during coding inside the protective cover 114. The execution device 2 can be a six-axis robot, a single-axis module, or a multi-axis module.

[0049] When the laser coding device of the present invention is in use:

[0050] Place the workpiece to be coded on the workbench 6;

[0051] The execution device 2 drives the floating coding head 1 to move to the position where coding is to be performed, and the camera assembly 13 takes pictures of the product to be coded for visual positioning, that is, to determine the position of the product to be coded;

[0052] The execution device 2 drives the floating coding head 1 to directly press on the workpiece to be coded, that is, to make the bottom end of the floating coding head 1 abut against the top surface of the workpiece to be coded;

[0053] Calculate according to the position given by the camera assembly 13, and deflect the content to be coded to the predetermined position of the product through the galvanometer assembly 1131, without the need for the execution device 2 to move;

[0054] When coding the same type of products with the same length and width dimensions but different thickness dimensions, the distance between the floating connection plate 122 and the fixed connection plate 121 of the floating coding head 1 is adaptively adjusted according to the thickness dimension of the product to be coded, and when coding products to be coded with different thickness dimensions, the fixed connection plate 121 is in the same position, that is, there is no need for the execution device 2 to move;

[0055] After coding is completed, the camera assembly 13 directly takes pictures and identifies the coding area, which can not only judge the coding effect, but also input the content after coding into the system, facilitating docking with users;

[0056] If it is judged that the coding effect is unqualified, the system can be directly notified, or the floating coding head 1 can be controlled to perform secondary coding.

[0057] The coding head assembly 11 of the present invention cooperates with the camera assembly 13 to complete the intelligent application mode of multi-functional combination of OCR content recognition, judgment of coding effect, and product visual positioning.

[0058] When coding products to be coded within a certain size range, the present invention does not require the execution device 2 such as a six-axis robot to move. Coding is completed through the positioning position provided by the camera assembly 13 and the deflection of the galvanometer assembly 1131, and the distance between the floating connection plate 122 and the fixed connection plate 121 is adaptively adjusted according to the size of the product to be coded; it can save the robot movement time, reduce the manual debugging time and difficulty, and complete marking faster.

[0059] In terms of adaptability to different products, the present invention has a wider application range, can code different surfaces of the same product, and is stable and reliable.

[0060] When coding the same type of products with the same length and width dimensions but different thickness dimensions, the floating coding head 1 can reduce the manual debugging and operation situations, reduce the labor intensity of workers, and increase the production efficiency of the enterprise.

[0061] Adding a camera component 13 to the floating dock 1 can improve the degree of intelligence; the device's determination of whether the product marking content is qualified can reduce the working intensity of workers; real-time determination can reduce the production of unqualified products in case of equipment failure and save production costs; the visual positioning function of the camera component 13 enables the product to be placed arbitrarily within a fixed area and still complete coding, reducing the production cost of the positioning tooling and also reducing the working intensity of workers; the newly added OCR function can better interface with MES systems of different manufacturers for intelligent applications.

[0062] In the present invention, specific examples are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, based on the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation on the present invention.
