[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0049] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0050] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0051] See also Figure 3 Now, the marking and positioning device provided in the embodiment of the present application is described. The marking and positioning device provided in the embodiment of the present application is used to position the product 10.

[0052] Reference Figure 1 and Figure 2 The product 10 includes a detection surface 11 and a plurality of marking surfaces, and the detection surface 11 and each of the marking surfaces form an angle. The detection surface 11 and each of the marking surfaces are located on the upper side of the product 10. Before marking, it is necessary to first detect the detection surface 11 with a detection element (such as a probe), read the information, and then mark each of the marking surfaces in turn after confirmation. Among them, the product 10 can be a remote control.

[0053] In the marking device, the direction of the detection element is consistent with the direction of the marking laser, that is, the detection marking direction. Since the orientation of each marking surface is at an angle to the orientation of the detection surface 11, after detection, the orientation of each marking surface needs to be adjusted before marking can be performed.

[0054] In some embodiments, the detection and marking direction is a vertical direction, then the detection surface 11 needs to be adjusted to a horizontal level during detection, and each marking surface also needs to be adjusted to a horizontal level during marking. In some embodiments, the detection and marking direction is an inclined direction, and the angle with the horizontal plane can be 85°, 60°, 45°, etc. Correspondingly, the detection surface 11 and each marking surface need to be adjusted to be perpendicular to the detection and marking direction during detection or marking.

[0055] Reference Figure 3 The marking and positioning device includes a base 20, a positioning member 30, an elastic component 40 and a driving mechanism 50.

[0056] The base 20 is a base for the positioning member 30 to be installed for rotation. The positioning member 30 is rotatably arranged on the base 20 around a first axis X. The first axis X is arranged horizontally. The product 10 can be installed on the positioning member 30. The positioning member 30 can be installed and fixed to the product 10. Then, since the positioning member 30 is rotatably installed on the base 20 around the horizontal first axis X, when the positioning member 30 rotates, the inclination angle of the product 10 will change. Correspondingly, the detection surface 11 and each marking surface on the product 10 will also change accordingly.

[0057] It can be understood that the positioning member 30 has a mounting area that matches the shape of the product 10 to mount and fix the product 10 and prevent the product 10 from shifting and moving during the rotation of the positioning member 30 .

[0058] Reference Figure 4 The elastic component 40 is disposed between the positioning member 30 and the base 20 , and the elastic component 40 enables the positioning member 30 mounted with the product 10 to be in the first position, and the detection surface 11 is perpendicular to the detection marking direction.

[0059] When the positioning member 30 is not installed on the product 10, it can be in the first position or not in the first position. When the product 10 is installed on the positioning member 30, the weight of the positioning member 30 plus the product 10 and the elastic force of the elastic component 40 reach a balance, so that the positioning member 30 is in the first position under the elastic force of the elastic component 40. That is, if the positioning member 30 is in the first position when the product 10 is not installed, then after the product 10 is installed, the position of the positioning member 30 remains unchanged and is still in the first position. If the positioning member 30 is not in the first position when the product 10 is not installed, then after the product 10 is installed, the position of the positioning member 30 moves and rotates to the first position.

[0060] In the first position, the angle of the positioning member 30 is such that the detection surface 11 is perpendicular to the detection marking direction. At this time, the detection element (such as a probe) of the marking device can approach the detection surface 11 and make vertical contact with the detection surface 11 to read information from the detection surface 11, so as to control the subsequent marking action according to the read information.

[0061] It should be noted that when the positioning member 30 is in the first position, the driving mechanism 50 may not apply a force to the positioning member 30, or the force applied by the driving mechanism 50 to the positioning member 30 may be different in magnitude and / or direction from the force when the positioning member 30 is in the second position and the third position.

[0062] Reference Figure 3 , Figure 5 and Figure 6The driving mechanism 50 is used to drive the positioning member 30 to rotate around the first axis X so that any marking surface is perpendicular to the detection marking direction. The driving mechanism can drive the positioning member to rotate so that the marking surface is perpendicular to the detection marking direction. After the marking surface is marked, the positioning member is continued to be driven to rotate so that another marking surface is perpendicular to the detection marking direction, and the marking is continued until all marking surfaces are marked.

[0063] Based on the above structure, the embodiment of the present application can automatically adjust the detection surface and multiple marking surfaces of the product to be perpendicular to the direction of the probe or marking laser through the cooperation of the elastic component and the driving mechanism. The switching is convenient, no manual adjustment is required, and the production efficiency is higher.

[0064] Reference Figure 5 , the plurality of marking surfaces include a first marking surface 12 and a second marking surface 13;

[0065] Among them, refer to Figure 3 The driving mechanism 50 includes a first driving component 51 and a second driving component 52.

[0066] Reference Figure 4 and Figure 5 The first driving component 51 is disposed on the base 20 and located at one end of the positioning member 30. The first driving component 51 is used to drive the positioning member 30 to rotate to a second position. When the positioning member 30 is in the second position, the first marking surface 12 is perpendicular to the detection marking direction.

[0067] The first driving assembly 51 can drive the positioning member 30 to overcome the elastic force of the elastic assembly 40 and rotate to the second position so that the first marking surface 12 is perpendicular to the detection marking direction. It can be understood that the first driving assembly 51 can push or pull the positioning member 30 to rotate.

[0068] Reference Figure 4 and Figure 6 The second driving component 52 is disposed on the base 20 and located at the other end of the positioning member 30. The second driving component 52 is used to drive the positioning member 30 to rotate to a third position. When the positioning member 30 is in the third position, the second marking surface 13 is perpendicular to the detection marking direction. The second driving component 52 can drive the positioning member 30 to overcome the elastic force of the elastic component 40 and rotate to the third position so that the second marking surface 13 is perpendicular to the detection marking direction. It can be understood that the second driving component 52 can push or pull the positioning member 30 to rotate.

[0069] Reference Figure 3Specifically, the first driving assembly 51 includes a first connecting plate 511, a first driver 512, and a first driving head 513. The first connecting plate 511 is disposed at one end of the base 20 away from the second driving assembly 52, the first driver 512 is disposed on the first connecting plate 511, and the first driving head 513 is connected to the first driver 512, and can drive the positioning member to rotate to the second position under the drive of the first driver 512.

[0070] The first connecting plate 511 connects and fixes the base 20 and the first driver 512. The first driving head 513 can be located above the positioning member 30. When the first driver 512 drives the first driving head 513 to descend, the first driving head 513 can press down one end of the positioning member 30, thereby driving the positioning member 30 to rotate to the second position. Or the first driving head 513 can be located below the positioning member 30. When the first driver 512 drives the first driving head 513 to move upward, the first driving head 513 can lift up one end of the positioning member 30, thereby driving the positioning member 30 to rotate to the second position. Specifically, the direction of pressing down or lifting up can be selected according to the positional relationship between the first position and the second position to drive the positioning member 30 to rotate. Specifically, the first driver 512 can be a cylinder.

[0071] Reference Figure 3 Specifically, the second driving assembly 52 includes a second connecting plate 521, a second driver 522, and a second driving head 523. The second connecting plate 521 is disposed at one end of the base 20 away from the first driving assembly 51; the second driver 522 is disposed on the second connecting plate 521; the second driving head 523 is connected to the second driver 522, and can drive the positioning member to rotate to the third position under the drive of the second driver 522.

[0072] The second connecting plate 521 connects and fixes the base 20 and the second driver 522. The second drive head 523 can be located above the positioning member 30. When the second driver 522 drives the second drive head 523 to descend, the second drive head 523 can press down one end of the positioning member 30, thereby driving the positioning member 30 to rotate to the third position. Or the second drive head 523 can be located below the positioning member 30. When the second driver 522 drives the second drive head 523 to move upward, the second drive head 523 can lift up one end of the positioning member 30, thereby driving the positioning member 30 to rotate to the third position. Specifically, the direction of pressing down or lifting can be selected to drive the positioning member 30 to rotate according to the positional relationship between the first position, the second position and the third position. Specifically, the second driver 522 can be a cylinder.

[0073] The first driving head 513 and the second driving head 523 may be L-shaped, with one end connected to the driver and the other end extending out to face the positioning member 30 to drive the positioning member 30 to rotate.

[0074] Reference Figure 3 The base 20 includes a bottom plate 21 and a hinge support 22 provided on the bottom plate 21, and the middle part of the positioning member 30 is rotatably connected to the hinge support 22. The hinge support 22 is fixed on the bottom plate 21, and the positioning member 30 is rotatably connected to the hinge support 22. The positioning member 30 can rotate on the hinge support 22 to change its direction. There are two hinge supports 22, which are located on both sides of the bottom plate 21. The two hinge supports 22 are rotatably connected to the positioning member 30 at the same time, and the positioning member 30 is suspended, so that the positioning member 30 is separated from the bottom plate 21, so that the positioning member 30 has space to rotate. In actual use, when one end of the positioning member 30 rotates to abut against the bottom plate 21, the positioning member 30 is located in the second position, and when the other end of the positioning member 30 rotates to abut against the bottom plate 21, the positioning member 30 is located in the third position. That is, the contact between the positioning member 30 and the bottom plate 21 ensures the stability of the positioning member 30 in the second position and the third position.

[0075] Reference Figure 4 , the elastic component 40 includes a first elastic member 41 and a second elastic member 42; the first elastic member 41 is located on one side of the hinge support 22, one end of the first elastic member 41 abuts the base 20, and the other end abuts the positioning member 30; the second elastic member 42 is located on the other side of the hinge support 22, one end of the second elastic member 42 abuts the base 20, and the other end abuts the positioning member 30. That is, by arranging two elastic members on both sides of the hinge support 22, the positioning member 30 is located in the first position through the support of the two elastic members. When the positioning member 30 rotates to the second position, the first elastic member 41 is further compressed, and the second elastic member 42 recovers or extends. When the positioning member 30 rotates to the third position, the second elastic member 42 is further compressed, and the second elastic member 42 recovers or extends. Specifically, the first elastic member 41 and the second elastic member 42 can be compression springs.

[0076] Reference Figure 4 , Figure 5 and Figure 6 The positioning member 30 has an inclined first abutting surface 31 at one end facing the bottom plate 21, and an inclined second abutting surface 32 at the other end. When the positioning member 30 rotates until the first abutting surface 31 abuts against the bottom plate 21, the positioning member 30 is located at the second position, and when the positioning member 30 rotates until the second abutting surface 32 abuts against the bottom plate 21, the positioning member 30 is located at the third position. That is, the abutment of the first abutting surface 31 and the second abutting surface 32 with the bottom plate 21 makes the positioning member 30 more stable in the second position and the third position.

[0077] Reference Figure 3 The positioning member 30 includes a support plate 33 and a plurality of limit blocks 34, the plurality of limit blocks 34 are arranged on the support plate 33, and each of the limit blocks 34 surrounds a positioning area 35 for the installation and positioning of the product 10, and the inner side of each of the limit blocks 34 can abut against the edge of the product 10. The plurality of limit blocks 34 surround a positioning area, and the positioning area 35 is a contoured area, and the shape is adapted to the shape of the product 10, so that after the product 10 is installed in the positioning area 35, the inner side of the limit block 34 abuts against the edge of the product 10, thereby limiting the movement of the product 10 in all directions, and limiting and fixing the product 10.

[0078] Reference Figure 5 and Figure 7 , the marking and positioning device also includes a rotating table 60, the base 20 is arranged on the rotating table 60, and the rotating table 60 can drive the base 20 to rotate at a preset angle. In actual production, the conveying direction of the product 10 is not necessarily the same as the direction when marking, and there may be a certain angle. Therefore, when the product 10 is conveyed, the rotating table 60 can be rotated first so that the direction of the positioning member 30 is the same as the direction of the conveyed product 10, and then the product 10 is moved to the positioning member 30 by the robot arm. Then the rotating table 60 rotates the preset angle again, and then marking is performed. Among them, the preset angle can be 30°, 45°, 60°, 90°, 120°, etc. In some preferred embodiments, the preset angle is 90°.

[0079] Reference Figure 3 and Figure 5 The marking and positioning device further includes a substrate 70 and a buffer plunger 71. The rotating table 60 is disposed on the substrate 70, and the buffer plunger 71 is disposed on the substrate 70. When the rotating table 60 reciprocates to a preset angle, it abuts against the buffer plunger 71. The buffer plunger 71 can buffer the rotation of the rotating table 60, and is used to provide a buffering force when the rotating table 60 as a whole rotates the product 10 to the marking position by a preset angle, so as to prevent the product 10 from being subjected to a large impact force and moving.

[0080] An embodiment of the present application further provides a marking device, comprising a marking head and a marking positioning device as described in any one of the above items, wherein the marking head is used to emit the marking laser.
