Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] In this article, when it is mentioned that the first component is located on the second component, this may mean that the first component can be directly formed on the second component, or a third component can be inserted between the first component and the second component. In addition, in the drawings, for the effective description of the technical content, the thickness of the components may be exaggerated or reduced.

[0027] In this document, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." modify the entire list of elements when following a list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0028] The terms used herein are only for describing specific exemplary configurations and are not intended to be limiting. As used herein, the singular articles "a", "an", and "the" may also be intended to include the plural forms, unless it is clearly stated otherwise in the context. The terms "comprising", "including", and "having" are inclusive, and thus specify the presence of the specified features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or their combinations.

[0030] It has been found through research that in the related art, the label is horizontally attached to the PCBA circuit board. However, the thermal expansion and contraction of the PCBA circuit board during operation may cause the label to fall off. At the same time, bubbles are generated when the label is horizontally attached, and the generation of bubbles also easily accelerates the falling off of the label. The falling off of the label will cause the subsequent operations to be unable to recognize the label.

[0031] Therefore, how to avoid the label from falling off during the thermal expansion and contraction of the PCBA circuit board is a technical problem that urgently needs to be solved in the art.

[0032] Regarding the defects existing in the above solutions and the reasons for their occurrence, they are all the results obtained by the inventors through practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed in this disclosure for the above problems should both be the contributions made by the inventors to this disclosure during the disclosure process.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0034] Hereinafter, some embodiments of the present invention will be described in detail with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0035] As Figures 1 to 9 shown, at least one embodiment provides a fully automatic labeling machine for PCBA production, including: a conveyor belt 1, which is adapted to drive the PCBA circuit board 6 to horizontally move to the labeling station. Further, a positioning device 10 is arranged to be lifted and lowered at the labeling station of the conveyor belt 1, and the positioning device 10 is adapted to limit the horizontal movement of the PCBA circuit board 6. The positioning device 10 includes: a positioning block 101, on the side wall of which a lifting cylinder is arranged; a supporting plate 102, which is vertically fixed at the end of the piston rod of the lifting cylinder; adjusting cylinders 103, two of the adjusting cylinders 103 are respectively arranged on both sides of the supporting plate 102, and a limiting member 104 is arranged at the end of the piston rod of each adjusting cylinder 103, and the limiting member 104 is adapted to clamp the PCBA circuit board 6 from both sides. After the PCBA circuit board 6 moves to the labeling station, the lifting cylinder drives the supporting plate 102 to move upward, and the two limiting members 104 first clamp and limit the PCBA circuit board 6 from both ends; a plurality of suction cups 105 are arranged in a matrix on the supporting plate 102, and the suction cups 105 are communicated with a negative pressure air pump, and the suction cups 105 are adapted to suck the bottom wall of the PCBA circuit board 6 by negative pressure.

[0036] In this embodiment, a label is attached to the surface of the PCBA circuit board for convenient identification in subsequent production management and quality control. Therefore, a high-strength adhesive is not used when attaching the label, and the label may need to be torn off when necessary. In other fields, such as the automotive or aerospace fields, high-strength adhesives are required for labels. However, the glue of such adhesives can cause chemical contamination to the PCBA circuit board. In the anti-detachment technology for the food and drug packaging fields, the label is pre-coated with hot melt adhesive and has surface microstructures (to increase friction). However, there are still the following limitations. First, the heat resistance is insufficient: the hot melt adhesive is prone to softening and failure under the high-temperature working environment (>85°C) of the PCBA. Second, chemical contamination: the volatile substances of the colloid may corrode the solder joints of the circuit board. Therefore, there are insurmountable obstacles to the cross-field transfer of label anti-detachment in other fields. In this embodiment, the wrinkled area of the label avoids the identification area and resolves the contradiction between stress release and identification clarity. Therefore, the transfer from other fields cannot be applied to this PCBA circuit board field.

[0037] Reference appendix Figure 2 , a label feeding device 2, which is arranged on one side of the conveyor belt 1 and is adapted to support the label 5; the label feeding device 2 is arranged on the side of the conveyor belt 1 away from the labeling device 3 for storing and limiting the label 5 so that the middle part of the label 5 bulges upward. A labeling device 3, which is arranged above the conveyor belt 1; the labeling device 3 includes a horizontal moving pair and a labeling cylinder arranged on the side wall of the slider of the horizontal moving pair for pressing the label 5, a pressing roller 30; the pressing roller 30 is arranged at the end of the piston rod of the labeling cylinder. A loading manipulator 4, which is arranged above the conveyor belt 1; the loading manipulator 4 is used for sucking the label 5 by negative pressure and attaching it to the surface of the circuit board. Among them, the label feeding device 2 drives the label 5 to move towards the conveyor belt 1 so that the middle part of the label 5 is in a convex shape; the loading manipulator 4 is adapted to suck the label 5 by negative pressure to first adhere the two ends of the label 5 to the surface of the PCBA circuit board 6; the pressing roller 30 of the labeling device 3 rolls from the middle part of the label 5 to both ends in sequence so that the adhesion parts of the two ends of the label 5 and the PCBA circuit board 6 are wrinkled.

[0038] Reference appendix Figure 3The label delivery device 2 comprises: a fixed plate 21, which is horizontally arranged, and two support plates 22 are vertically arranged on both sides of the length direction; a label delivery disc 23 slidably arranged on the side wall of the support plate 22, and the two label delivery discs 23 are staggered up and down; the horizontal heights of the two label delivery discs 23 are different, and when one label delivery disc 23 moves toward the conveyor belt 1, the other label delivery disc 23 moves away from the conveyor belt 1; a movable toothed disc is rotatably arranged on the side wall of the support plate 22 and meshes with the two label delivery discs 23; a driving motor is arranged on the outer wall of the support plate 22, and the driving toothed disc 24 is sleeved on the outer wall of the rotating shaft of the driving motor; wherein the driving toothed disc 24 rotates forward and backward to move one of the label delivery discs 23 toward the conveyor belt 1. A plurality of placement grooves 25 are opened on the label delivery disc 23 along the length direction, and the groove depth of the placement grooves 25 gradually deepens from the middle to the two ends.

[0039] Reference Figure 2 and Figure 4 A horizontal groove 26 is respectively provided at both ends of the placement groove 25. When the loading robot 4 moves above the placement groove 25, the horizontal groove 26 is aligned with the negative pressure suction cup 40 of the loading robot 4 to ensure the stability of the negative pressure suction cup 40 when adsorbing the label 5.

[0040] Continue to refer to the attached Figure 3 The bottom wall of the placement slot 25 is provided with a plurality of through holes 27, which are respectively arranged in the middle of the placement slot 25 and at both ends near the horizontal slot 26. The arrangement of the through holes 27 prevents the bottom wall of the label 5 from being adsorbed by the bottom wall of the placement slot 25 when the label 5 falls off from the placement slot 25, so that the label 5 can be more smoothly removed from the placement slot 25.

[0041] Continue to refer to the attached Figure 3 In order to improve the stability of the horizontal movement of the label delivery disk 23, the side wall of the label delivery disk 23 is provided with a linear rack 29 adapted to the driving gear disk 24, and the two linear racks 29 are arranged opposite to each other; a plurality of support rollers 28 are evenly distributed on the surface of the fixed plate 21, and the support rollers 28 are suitable for abutting against a linear rack 29 located below.

A horizontal groove 26 is respectively arranged at both ends of the placing groove 25. When the loading manipulator 4 moves above the placing groove 25, the horizontal groove 26 is aligned with the negative pressure suction cup 40 of the loading manipulator 4.

[0043] At least one embodiment provides a labeling method for a full-automatic labeling machine, characterized in that the labeling method comprises: The label feeding device 2 drives the label 5 to move towards the conveyor belt 1, so that the middle of the label 5 is in a convex shape. The setting of the placing groove 25 makes the middle of the label 5 bulge upward, while both ends are horizontally arranged; the loading manipulator 4 is adapted to negatively adsorb the label 5 to first adhere both ends of the label 5 to the surface of the PCBA circuit board 6. At this time, the middle of the label 5 bulges upward; when the negative pressure suction cup 40 adsorbs the label 5, the negative pressure suction cup 40 adsorbs the horizontal areas at both ends of the label 5; when the negative pressure suction cup 40 moves above the surface of the PCBA circuit board 6 and places the label 5, first make both ends of the label 5 contact and adhere to the surface of the PCBA circuit board 6. The pressing roller 30 of the labeling device 3 rolls from the middle of the label 5 to both ends in sequence. The pressing roller 30 pushes from the middle to both ends of the label. In this way, the bubbles that might have formed in the label 5 will escape from both sides of the two arches respectively, and no bubbles will be formed on the label, ensuring the integrity of the two-dimensional code on the label during subsequent circulation; so that the adhesion parts of both ends of the label 5 and the PCBA circuit board 6 are in folds. After the left and right sides of the label are respectively compacted, the left and right arches will respectively form a fold at both ends of the label. This fold will form an expansion buffer area during the subsequent heating process of the PCBA board, avoiding damage to the label due to stress.
