Description

Technical Field

[0001] The utility model relates to the technical field of assembly line production, in particular to a processing device for assembly line marking. Background Art

[0002] In the field of assembly line production technology, in the specific process of marking on products, in order to improve processing efficiency, flying marking is usually used. Flying marking is also called dynamic marking, which is different from static marking. This method is to quickly mark the workpieces on the assembly line while the assembly line is moving. This processing method can not only greatly improve work efficiency, but also facilitate factory automation integration based on the working method of the assembly line. At present, flying marking has been widely used in production activities in various industries such as food, medical, 3C electronics, etc.

[0003] However, due to the accumulated motion error of the assembly line and the corresponding time error of the sensor, although there is software algorithm compensation for marking in the flow, line deformation will still occur during marking, affecting the processing quality of the marking process. The marking accuracy of conventional flying marking often exceeds 1mm. When customers have high requirements for marking accuracy, it is difficult to balance processing efficiency and processing quality in the marking process. Utility Model Content

[0007] In this application, a material diverting device is added to divert the incoming material of the main pipeline to both sides. At this time, marking machines can be symmetrically set on both sides of the main pipeline to realize parallel processing and improve processing efficiency; assisted by a multi-station rotary processing device, on the one hand, the processing efficiency can be further improved, and on the other hand, the workpiece can be brought to the marking position for static marking to improve the processing quality.

[0008] The multi-station rotary processing device is a prior art, which rotates the clamped object so that the object can be circulated in multiple stations. Obviously, the multi-station rotary processing device here is used to clamp the workpiece to the marking position and load and unload materials, that is, the clamping mechanism of the multi-station rotary processing device must have a loading position, a marking position and a unloading position.

[0009] In some embodiments, a multi-station rotary processing device includes a rotatable base plate, to which a plurality of adapter plates are fixedly connected. The plurality of adapter plates are evenly distributed in the circumferential direction of the base plate. Each adapter plate is fixedly connected to a clamping mechanism, and the clamping mechanism is vertically slidably connected to the adapter plate.

[0010] In this embodiment, a plurality of adapter plates on the bottom plate are evenly distributed in the circumferential direction of the bottom plate.

[0011] In some embodiments, a kicking device is also included. The multi-station rotary processing device is a four-station rotary processing device. Four adapter plates are connected to the base plate. The four clamping mechanisms correspond to the loading position, marking position, identification position and unloading position in sequence along the rotation direction of the base plate.

Along the running direction of the kicking assembly line, the kicking rod can be rotated to the oblique direction of the main waterline.

[0018] In this embodiment, the kicking rod moves in a rotational manner, which is more suitable for the use scenario where the kicking devices are symmetrically arranged on both sides compared to the linear motion kicking more commonly used in the prior art; along the running direction of the kicking assembly line, the kicking rod can be rotated to the oblique direction of the mainstream assembly line. Combined with the aforementioned kicking rod being arranged on the side away from the mainstream assembly line, qualified products can be merged from the kicking assembly line into the mainstream assembly line under the action of the kicking rod.

[0022] In this embodiment, the first driving device is a telescopic cylinder. Combined with the usage scenario here, only two working positions are required, so the telescopic cylinder is more economical and easier to implement.

DETAILED DESCRIPTION

[0032] The utility model is further described below in conjunction with the accompanying drawings.

[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] like Figure 1-Figure 4 As shown, the utility model provides a processing device for assembly line marking.

[0035] The processing device for assembly line marking includes a main pipeline 0, a material shifting device 1 and a multi-station rotary processing device 2; the material shifting device 1 is arranged on the main pipeline 0, and the material shifting device 1 includes a material blocking rod 11, a material shifting rod 12, a first incoming material sensor 13 and a first driving device 14, the material blocking rod 11 is arranged perpendicular to the running direction of the main pipeline 0, the first incoming material sensor 13 is used to sense the incoming material of the main pipeline 0, and the first incoming material sensor 13 and the first driving device 14 are electrically connected to drive the material shifting rod 12 to perform a linear reciprocating motion along the extension direction of the material blocking rod 11, and then shift the incoming material to both sides of the main pipeline 0; the multi-station rotary processing device 2 is symmetrically arranged on both sides of the main pipeline 0, and is used to clamp the workpiece to the marking position and load and unload the material, and the material shifting device 1 shifts the incoming material to the loading position of the multi-station rotary processing device 2.

[0036] In the present application, a material diverting device 1 is added to divert the incoming material of the main pipeline 0 to both sides. At this time, marking machines can be symmetrically arranged on both sides of the main pipeline 0 to realize parallel processing and improve processing efficiency; assisted by a multi-station rotary processing device 2, on the one hand, the processing efficiency can be further improved, and on the other hand, the workpiece can be brought to the marking position for static marking to improve the processing quality.

[0037] The multi-station rotary processing device 2 is a prior art, which clamps the material and rotates it so that the material can flow through multiple stations. Obviously, the multi-station rotary processing device 2 here is used to clamp the workpiece to the marking position and load and unload materials, so the clamping mechanism action of the multi-station rotary processing device 2 must include the loading position, marking position and unloading position. In this application, the loading position is the material shifting position of the aforementioned material shifting device 1, the marking position is the rotation to the marking machine operation position, and the unloading position is to bring the workpiece back to the main pipeline 0 or the next process after the marking is completed, such as the subsequent kicking device 3.

[0038] The blocking rod 11 is set to be perpendicular to the main pipeline 0, and plays a role of blocking the material, limiting the movement of the material along the running direction of the main pipeline 0. The material-moving rod 12 moves along the extension direction of the blocking rod 11, and is used to position the material perpendicular to the direction of the main pipeline 0. The combination of the two limits the material to the loading position of the multi-station rotary processing device 2. Among them, the multi-station rotary processing device 2 is a prior art, and the device is used in this application to clamp and operate the material. The first incoming material sensor 13 is installed on the blocking rod 11, which is used to sense the incoming material of the main pipeline 0, so as to provide information feedback and provide instructions for the action of the material-moving rod 12.

[0039] like Figure 2 As shown, two working positions of the material moving rod 12 are shown. Combined with the first incoming material sensor 13, it reciprocates between the two working positions, so that the incoming material is circulated and moved to both sides of the main pipeline 0, so as to be clamped by the multi-station rotary processing device 2 on both sides.

[0040] In this embodiment, the multi-station rotary processing device 2 includes a rotatable bottom plate 26, and a plurality of adapter plates 21 are fixedly connected to the bottom plate 26. The plurality of adapter plates 21 are evenly distributed in the circumferential direction of the bottom plate 26. Each adapter plate 21 is fixedly connected to a clamping mechanism 24, and the clamping mechanism 24 is vertically slidably connected to the adapter plate 21. The plurality of adapter plates 21 on the bottom plate 26 are evenly distributed in the circumferential direction of the bottom plate 26. At this time, the plurality of clamping mechanisms 24 can operate simultaneously, so that multiple stations can act simultaneously and the processing efficiency is improved.

[0041] Specifically, in this embodiment, if Figure 3 As shown, the bottom plate 26 can rotate under the drive of the rotary motor 25, and multiple adapter plates 21 are evenly distributed on the circumference of the upper end surface of the bottom plate 26. The lifting module 22 is installed on the adapter plate 21. The clamping mechanism 24 is connected to the lifting module 22 through the back plate 23. Under the action of the lifting module 22, the clamping mechanism 24 can move up and down relative to the adapter plate 21 to facilitate clamping materials, transportation, and loading and unloading. The lifting module 22 can adopt common options such as linear motors to drive lifting, which will not be repeated here.

[0042] In the present embodiment, a kicking device 3 is also included. The multi-station rotary processing device 2 is a four-station rotary processing device. Four adapter plates 21 are connected to the bottom plate 26. Four clamping mechanisms 24 correspond to the loading position, marking position, identification position and unloading position in sequence along the rotation direction of the bottom plate. The kicking device 3 is used to divert qualified materials and unqualified materials. A four-station rotary processing device is adopted, and the loading position, marking position, identification position and unloading position correspond in sequence along the rotation direction of the bottom plate 26. An identification position and a kicking device 3 are added, and the identification information and the kicking device 3 are linked to divert qualified materials and unqualified materials. In the present embodiment, the identification position is an anti-counterfeiting identification, which is not specifically limited here. It is used to detect whether the material is qualified. Common identification methods include CCD photography, code scanning identification, etc.

[0043] In combination with the above, in this embodiment, since the kicking device 3 is provided, the unloading position preferably leads directly to the kicking process.

[0044] In this embodiment, the four-station rotary processing device corresponds to four clamping mechanisms 24. Combined with the uniform distribution of the adapter plate 21, the adapter plate 21 and the corresponding clamping mechanism 24 are evenly distributed at 90 degrees on the circumference of the upper end surface of the bottom plate 26. The rotary motor 25 is used for the clamping mechanism 24 to carry the material to the next station, and the lifting module 22 facilitates the loading and unloading and avoiding of the clamping mechanism 24.

[0045] In this embodiment, two kicking devices 3 are included, and the kicking devices 3 are symmetrically arranged on both sides of the main pipeline 0, and each kicking device 3 corresponds to a multi-station rotary processing device 2. Each multi-station rotary processing device 2 corresponds to a kicking device 3 to avoid the control logic of the kicking device 3 being too complicated and inconvenient to implement; similar to the multi-station rotary processing device 2, the kicking devices 3 are symmetrically arranged on both sides of the main pipeline 0 to improve the overall integration.

[0046] In this embodiment, the kicking device 3 includes a kicking assembly line 31, a kicking rod 36, a second incoming material sensor 32 and a second driving device 35. The main assembly line 0 and the kicking assembly line 31 run in the same direction. The second incoming material sensor 32 and the second driving device 35 are electrically connected to drive the kicking rod 36 to move, thereby integrating qualified materials into the main assembly line 0. The kicking device 3 includes a kicking assembly line 31, and the kicking rod 36 can move to integrate qualified materials into the main assembly line 0.

[0047] In combination with the above, in this embodiment, since the kicking device 3 is provided, the unloading position preferably directly leads to the kicking assembly line 31 of the kicking process.

[0048] In this embodiment, the second incoming material sensor 32 is used to sense the incoming material of the kicking device 3. After sensing the material, the kicking rod 36 is controlled to operate according to the host computer instruction to achieve the function of diverting qualified materials and unqualified materials.

[0049] In this embodiment, the second driving device 35 can drive the kicking rod 36 to rotate. The rotation axis of the kicking rod 36 is set on the side of the kicking device 3 away from the main pipeline 0. Along the running direction of the kicking assembly line 31, the kicking rod 36 can be rotated to the direction oblique to the main pipeline 0. The kicking rod 36 moves in a rotating manner. Compared with the linear motion kicking that is more commonly used in the prior art, it is more suitable for the use scenario where the kicking device 3 is symmetrically arranged on both sides here; along the running direction of the kicking assembly line 31, the kicking rod 36 can be rotated to the direction oblique to the main pipeline 0. Combined with the aforementioned setting of the kicking rod 36 on the side away from the main pipeline 0, qualified products can be merged from the kicking assembly line 31 into the main pipeline 0 under the action of the kicking rod 36.

[0050] Combination Figure 1 and Figure 4 As shown, the kicking rod 36 and the second driving device 35 are connected to the side of the kicking device 3 away from the main pipeline 0. Obviously, the second driving device 35 and the kicking rod 36 do not move with the kicking pipeline 31. In this embodiment, the second driving device 35 and the kicking rod 36 are fixed to the side of the kicking device 3 away from the main pipeline 0 through the fixed base 34, and the mounting bracket 33 used to fix the second incoming material sensor 32 can also be connected to the second driving device 35 or the fixed base 34. Obviously, the mounting bracket 33 can also be set integrally with the fixed base 34.

[0051] Figure 4 The figure shows two working positions of the kick rod 36. When the incoming material is qualified, the kick rod 36 Figure 4 The solid line position in the figure is used to guide qualified materials to the main pipeline 0; when the incoming materials are unqualified materials, the kicking rod 36 is Figure 4 At the dotted line position in the figure, the kicking material pipeline 31 is not blocked at this time, the incoming materials will not be guided, and the unqualified materials will not be guided to flow into the main pipeline 0.

[0052] In this embodiment, the second drive device 35 is selected as a rotary cylinder to control the rotation of the aforementioned kicking rod 36. The first drive device 14 is a telescopic cylinder, and the material-moving rod 12 is driven by the telescopic cylinder to perform linear reciprocating motion along the extension direction of the material-blocking rod 11. Obviously, there are different implementations of linear motors, telescopic cylinders, etc. as power sources. Combined with the usage scenario here, only two working positions are required, so the aforementioned drive device is more economical and more convenient to implement.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
