Description

Technical Field

[0001] The present invention relates to a mass production technology of integrated welding and bending, and particularly to an integrated fixture and tooling for FPC welding and bending. Background Art

[0002] A flexible printed circuit (FPC) is a highly reliable and extremely flexible printed circuit board made of polyimide or polyester film as the substrate. FPC is also known as a flexible circuit board or a flexible printed circuit board, and is favored for its excellent characteristics such as light weight, thin thickness, and free bending and folding. FPC is a technology developed in the United States in the 1970s for the development of space rocket technology. By embedding a circuit design on a flexible and thin plastic sheet, a large number of precision components can be stacked and embedded in a narrow and limited space, thereby forming a flexible circuit. Such a circuit can be bent and folded at will, with light weight, small size, good heat dissipation, and convenient installation, breaking through the traditional interconnection technology. In the structure of a flexible circuit, the materials used include insulating films, conductors, and adhesives.

[0003] With the rapid development of new energy vehicles, intelligent driving vehicles, flexible mobile phones, and other intelligent devices, the demand for FPC has been widely proposed. For example, in the process of stacking and forming modules of soft-pack battery cells for new energy vehicles, laser welding or other welding methods are required to connect the battery cells in series and parallel. Before welding, the battery cell tabs need to be processed (bent, rolled) to ensure good and stable welding quality. This demand has increased sharply with the popularization of new energy vehicles and the like.

[0004] The existing welding and bending technologies adopt a single welding and bending mode, with low production efficiency and unable to meet the rapidly expanding application requirements.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Invention

[0006] The purpose of the present invention is to provide an integrated fixture and tooling for FPC welding and bending. By optimizing the structure of the integrated fixture for welding and bending, the working efficiency of the fixture is effectively improved, the operation accuracy is improved, and thus the convenience of the welding and bending operation is improved.

[0007] To achieve the above object, an embodiment of the present invention provides an FPC welding and bending integrated fixture, which includes a cooperatively arranged upper cover, a functional part and a base. The functional part is used to realize the welding and bending of the FPC line and the workpiece. The functional part includes a carrier, and the carrier includes a plurality of bearing areas arranged on the first main body. The bearing area includes a first station and a second station for cooperatively arranging the FPC line and the workpiece; a bending device is also arranged in cooperation with each bearing area. The bending device includes a first bending die, a second bending die and a first driving device. The first driving device provides a stroke for the first bending die and / or the second bending die to cooperate to realize bending. At least part of the workpiece and / or the FPC line is located on the stroke path between the first bending die and the second bending die. By pressing and opening between the first bending die and the second bending die along this stroke, the mold closing between the first bending die and the second bending die is realized to bend the workpiece and / or the FPC line, and the bending operation is performed on the part located on the stroke. Conversely, when the mold is opened, the workpiece is released.

[0008] During the working process, the fixture is properly installed on the tooling, and the FPC line and the workpiece to be welded are placed on the first station and the second station of the bearing area. After the corresponding FPC lines and workpieces are properly placed on each bearing area of the carrier, it can be regarded that the fixture has completed the preparation work.

At this time, the mold closing operation is performed. At this time, it can be noted that according to the design requirements, the part of the FPC line and the workpiece that needs to be bent is necessarily limited to an appropriate position so that it can be bent by closing the mold. After the bending is completed, the mold can be opened in the reverse direction, and then the welded and bent FPC line and workpiece can be taken out, and the above-mentioned operations can be repeated to perform the next batch of operations.

[0032] Combined with the detailed embodiments of the present invention, the technical solutions of the present invention will be described in an exemplary and detailed manner. However, it should be understood that the protection scope of the present invention is not limited by the detailed embodiments.

[0033] Unless otherwise clearly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "having" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0034] As Figures 1 to 11 shown, the FPC welding and bending integrated jig according to a preferred embodiment of the present invention includes a cooperatively arranged upper cover 100, a functional part, and a base 500. The functional part is protected and defined between the upper cover 100 and the base 500. The functional part is the main improvement point to achieve the innovation of the present invention. By optimizing the structure and design of the functional part, the large-scale, rapid, and high-precision welding and bending forming of the product are realized. When using the horizontal jig as shown in the figure, the upper cover 100 and the base 500 are respectively located above and below the functional part.

[0035] As Figure 1 shown, the upper cover 100 includes an upper cover main body. On the upper cover main body, corresponding to several loading areas on the carrier, several upper cover units are correspondingly arranged. Each upper cover unit is respectively provided with a first FPC wire part 111, a first workpiece part 113, and a first die part 112 corresponding to the first working station 411, the second working station 413, and the third working station 412. Similarly, in order to meet the positioning requirements, a first upper cover positioning hole 121 can also be correspondingly arranged on the upper cover main body. The first upper cover positioning hole 121 is appropriately arranged around the upper cover unit. Of course, multiple first upper cover positioning holes 121 can be arranged around each corresponding upper cover unit, and the number of first upper cover positioning holes 121 arranged between them can be the same or different, which can meet the positioning and matching requirements with the carrier, etc. In addition, a second upper cover positioning hole 122 can be additionally arranged on the upper cover main body to meet the positioning or transfer requirements. At this time, magnets can be arranged on both the first upper cover positioning hole 121 and the second upper cover positioning hole 122 to assist in positioning and handling.

[0036] As Figure 2As shown, the base 500 includes a base body. On the base body, several bearing areas corresponding to those on the vehicle are provided, and correspondingly, several base units are arranged. Each base unit is respectively provided with a second FPC line part, a second workpiece part, and a second mold part 514 corresponding to the first station 411, the second station 413, and the third station 412. The second mold part 514 can at least be used to provide a fixed installation position for the first driving device, such as for screw-connecting the cylinder body. Similarly, to meet the positioning requirements, the base body can also be correspondingly provided with first base positioning holes 521. The first base positioning holes 521 are appropriately arranged around the base unit. Of course, multiple first base positioning holes 521 can be arranged around each corresponding base unit, and the number of first base positioning holes 521 arranged between them can be the same or different, which can meet the positioning and matching requirements with the vehicle, etc. In addition, the base body can also be additionally provided with second base positioning holes 522 to meet the positioning or transfer requirements. At this time, magnets can be arranged in both the first base positioning holes 521 and the second base positioning holes 522 to assist in positioning and handling.

[0037] The functional part is used to realize the welding and bending of the FPC line and the workpiece, and the functional part includes a vehicle. As Figure 3 shown, the vehicle includes several bearing areas arranged on the first body 400. The bearing areas at least include a first station 411 for fittingly placing the FPC line and a second station 413 for placing the workpiece. To carry the bending device, the bearing area can also be correspondingly provided with a third station 412. At this time, as Figure 3 shown in, the third station 412 can be arranged at a position between the first station 411 and the second station 413. Similarly, to meet the positioning requirements, the first body 400 can also be correspondingly provided with first vehicle positioning holes 421. The first vehicle positioning holes 421 are appropriately arranged around the vehicle unit. Of course, multiple first vehicle positioning holes 421 can be arranged around each corresponding vehicle unit, and the number of first vehicle positioning holes 421 arranged between them can be the same or different, which can meet the positioning and matching requirements with the vehicle, etc. In addition, the first body 400 can also be additionally provided with second vehicle positioning holes 422 to meet the positioning or transfer requirements. At this time, magnets can be arranged in both the first vehicle positioning holes 421 and the second vehicle positioning holes 422 to assist in positioning and handling.

[0038] A bending device is also provided in cooperation with each bearing area. The bending device includes a first bending die, a second bending die, and a first driving device. The first driving device provides a stroke for the first bending die and / or the second bending die to cooperate to achieve bending. That is, the first driving device can displace the first bending die along the stroke direction for die closing (at this time, the first driving device can be a one-way moving device such as a cylinder, an oil cylinder, or a linear motor); it can also displace the second bending die along the stroke direction for die closing (similarly, at this time, the first driving device can be a one-way moving device such as a cylinder, an oil cylinder, or a linear motor); or the first bending die and the second bending die simultaneously displace towards each other along the stroke direction for die closing (at this time, the first driving device can be an opposing moving device such as two oppositely arranged cylinders, oil cylinders, or linear motors). The first bending die can adopt a structure as shown in Figure 9 shown, and the second bending die can adopt a structure as shown in Figure 10 shown.

[0039] As Figure 8 shown, a feasible solution of the first driving device is shown. The cylinder body can be arranged on the base 500, the piston 632 is arranged parallel to the upper surface of the base 500, and the piston joint 633 is connected to the connecting part 634. The connecting seat 635 is fixedly connected to the first bending die or the second bending die. The cylinder is controlled by the control button 631 to perform start / stop operations according to instructions, so as to meet the requirement of controlling the first bending die and the second bending die to perform die closing operations for bending after welding is completed. Of course, the first driving device can also be arranged in other positions, and only needs to meet the requirement of connecting the stroke driving parts such as cylinders, oil cylinders, or linear motors to the first bending die or the second bending die.

[0040] In order to meet the bending requirements, according to the design, the workpiece and / or the part to be bent on the FPC line should be limited to the stroke path between the first bending die and the second bending die. That is, according to the design, during the die closing process, the matching closing of the first bending die and the second bending die bends the designed bending position correspondingly.

[0041] Furthermore, the first bending die includes a first die body 610 and a first mating part formed on the first die body 610; the second bending die includes a second die body 620 and a second mating part formed on the second die body 620; in the stroke direction, the first mating part and the second mating part can be arranged oppositely in a cooperative manner, and through the transfer of at least any one of the first mating part and the second mating part, the cooperation or engagement during the die closing process is achieved, thereby realizing the bending that meets the design requirements. Here, the bending design can be in multiple aspects such as size, shape, and angle.

[0042] Further, to achieve the aforementioned bending, as shown in the figure, the first mating portion may include a first protruding portion 611 and a second protruding portion 613 arranged in parallel. The first protruding portion 611 and the second protruding portion 613 are juxtaposed and face the second mating portion. A first recessed portion 612 is formed between the first protruding portion 611 and the second protruding portion 613; the second mating portion includes a third protruding portion 621, and the third protruding portion 621 faces the first mating portion; at this time, to achieve bending, the third protruding portion 621 here can cooperate with the first protruding portion 611 or the second protruding portion 613 or the first recessed portion 612 in the stroke direction.

[0043] Furthermore, in the situation shown in the figure, the projection of the first recessed portion 612 formed between the first protruding portion 611 and the second protruding portion 613 on the first mating portion in the paper plane direction is wedge-shaped, and the included angle formed by this projection is preferably 60°. When the third protruding portion 621 cooperates with the first recessed portion 612, the tip included angle of the third protruding portion 621 should also meet the matching requirement of this angle. Both the first protruding portion 611 and the second protruding portion 613 are provided at the end of the first mating portion. The second mating portion includes a third protruding portion 621, and the third protruding portion 621 is provided at the end of the second mating portion. The third protruding portion 621 can be used to make a close fit with a part of the first protruding portion 611 according to design needs; of course, this close fit can also occur with the second protruding portion 613; when the cooperation with the first recessed portion 612 occurs, it is equivalent to making a close fit with two adjacent surfaces of the first protruding portion 611 and the second protruding portion 613.

[0044] Furthermore, as shown in the figure, the third protruding portion 621 of the second mating portion is provided on the second mating body, and the second mating body can be block-shaped. At this time, the third protruding portion 621 protrudes and is formed on a side surface of the second mating body, that is, the tail of the third protruding portion 621 is connected and fixed to the second mating body, and the head of the third protruding portion 621 can be designed in a pointed ridge shape for cooperating with the first recessed portion 612, that is, its cross-section can be designed as a pointed cone shape.

[0045] The first protrusion 611 and the second protrusion 613 of the first mating part can be arranged side by side and spaced apart on the first mating body (the space therebetween is the first recess 612, and its arrangement can be set according to the requirements of bending mating, and it can be formed by the vacancy formed by the positions of the first protrusion 611 and the second protrusion 613 near the head. At this time, the part of the first protrusion 611 and the second protrusion 613 near their tails can also be closed according to the design requirements), and the first mating body can also be in a block shape. At this time, both the first protrusion 611 and the second protrusion 613 can be prominently formed on one side surface of the first mating body, that is, the tails of the first protrusion 611 and the second protrusion 613 are fixedly connected to one side surface of the first mating body. And the first protrusion 611 can be arranged at the edge position of the first mating body. At this time, when observed from a perspective perpendicular to the paper surface, one side part of it can be set as a plane parallel to the same side surface of the first mating body, while the other side part opposite to the first protrusion 611 is set as an inclined surface, so as to form a slightly sharp end at the end of the first protrusion 611, and the first protrusion 611 is away from the side surface of the main body, so its end can be formed by two intersecting side surfaces. This enables an effective mating structure to be formed between the first mating part and the second mating part to provide a mating form that meets the requirements.

[0046] As an implementation manner, in order to further define and optimize the working process to improve efficiency and accuracy, the functional part can also include a limiting part cooperatively arranged on the carrier. The limiting part has the function of limiting the FPC line, the workpiece, etc., so as to prevent deviation and improper mating during the welding and bending processes, which may reduce the quality of the finished product. For example Figure 4As shown, the limit part may include a second body 300 which has a defining structure for defining the formation or position of the FPC line and / or the workpiece. At least several first limit grooves 311 corresponding to the FPC line are provided on the second body 300. In the working state, the FPC line is defined to be placed in the first limit grooves 311. The limit part is also provided with several second limit grooves 313 corresponding to the workpiece. In the working state, the workpiece is defined to be placed in the second limit grooves 313. At this time, at least part of the main bodies of the FPC line and the workpiece are restricted in the first limit grooves 311 and the second limit grooves 313, forming a nested engagement form to meet the purpose of restricting both during the working process, avoiding possible deviations, etc., thus undoubtedly improving the quality and efficiency of welding and bending. Of course, in order to meet the matching requirements of the bending device, such as meeting the setting requirements of the first bending die or the second bending die or the first driving device, the second body 300 may also be correspondingly provided with a third limit groove 312, and the third limit groove 312 is located between the first limit groove 311 and the second limit groove 313. Similarly, in order to meet the positioning requirements, the first limit positioning holes 321 may also be correspondingly provided on the second body 300. The first limit positioning holes 321 are appropriately arranged around the limit part. Of course, multiple corresponding ones may be provided around the limit part, and the number of the first limit positioning holes 321 may be the same or different from each other, which can meet the positioning and matching requirements for limiting, etc. In addition, a second limit positioning hole 322 may be additionally provided on the second body 300 to meet the positioning or transfer requirements. At this time, magnets may be provided in both the first limit positioning holes 321 and the second limit positioning holes 322 to assist in positioning and handling.

[0047] Furthermore, in order to strengthen the effect of the limiting part, the functional part may also be cooperatively arranged on the wire pressing part of the limit part. Such as Figure 5A shown situation, the wire pressing includes a third body 200, on which a number of first pressing parts 314 and / or a number of second pressing parts 315 are provided. The first pressing part 314 cooperates with the first limiting groove to limit the FPC line, and the second pressing part 315 cooperates with the second limiting groove to limit the workpiece. The first pressing part 314 and the second pressing part 315 can exist in a structural form that does not affect operations such as welding and bending. For example, they can be partitions (the partitions can be continuously associated with the exposed surfaces of both to form pressing) or fences (the bars of the fences can be continuously associated with the exposed surfaces of both to form pressing) or branched structures (convex structures that partially and discontinuously protrude to the exposed surfaces of both) etc. arranged at appropriate positions for limiting the FPC line and the workpiece. The wire pressing part should appropriately expose the welding points and bending design positions during work, so its actual form can be determined according to the requirements of product design and processing, etc. Similarly, to meet the positioning requirements, first wire pressing positioning holes can also be correspondingly provided on the third body 200. The first wire pressing positioning holes are appropriately arranged around the wire pressing part. Of course, multiple first wire pressing positioning holes can be provided around the corresponding wire pressing part, and the number of first wire pressing positioning holes set between each other can be the same or different, which can meet the positioning and matching requirements with wire pressing, etc. In addition, a second wire pressing positioning hole 222 can be additionally provided on the third body 200 to meet the positioning or transfer requirements. At this time, magnets can be provided in both the first wire pressing positioning holes and the second wire pressing positioning hole 222 to assist in positioning and handling.

[0048] As an implementation manner, in order to at least meet the combined assembly requirements of the carrier, the limiting part, the wire pressing part, etc., the jig can also be provided with a magnetic positioning device. The magnetic positioning includes a positioning hole and a magnet arranged in the positioning hole in a matching manner. To meet the positioning requirements, the magnets in the positioning holes on the adjacent assembly surfaces of the carrier, the limiting part, and the wire pressing part should correspondingly meet the requirement of "opposite-sex attraction". The positioning holes are correspondingly arranged on the first body 400 and / or the second body 300 and / or the third body 200. At this time, the positioning holes can exist in the form of non-through counterbores; of course, they can also exist in the form of through holes penetrating the corresponding bodies. The positioning holes can be first positioning holes that focus on positioning, second positioning holes that focus on magnetic attraction, etc.

[0049] Further, in order to further meet the requirements of magnetic positioning, the exposed magnetic pole polarities, hole spacings, etc. of the first positioning holes on the same main body can be encoded. For example, the positions and spacings of the positioning holes provided on the first main body 400 can be designed, and at the same time, the magnetic pole polarities of the magnets at different positions are defined; and based on this, the positions, spacings, and magnetic poles of the positioning holes on the adjacent surfaces of the second main body 300 are correspondingly designed. Thus, the law of "opposite poles attract" is restricted. When the two cooperate, only qualified positioning can meet the requirements of rapid magnetic attraction. The first positioning holes can refer to the first wire-pressing positioning holes, the first limiting positioning holes 321, the first carrier positioning holes 421, and the first base positioning holes 521. The second positioning holes can refer to the second wire-pressing positioning holes 222, the second limiting positioning holes 322, the second carrier positioning holes 422, and the second base positioning holes 522

[0050] Further, of course, when the magnet is disposed in the second positioning hole, it can also be exposed to the outside to meet the requirements of handling and transferring. For example, for the convenience of handling and transferring, additional magnets can be provided on the part of the carrier that is exposed outside the limiting part and the wire-pressing part, so that it can be easily adsorbed and transferred by a magnetic handle. At this time, the second positioning hole can be only provided in the exposed part of one of the carrier, the limiting part, and the wire-pressing part, or can be provided on the three in the form of a coaxial through hole.

[0051] As an implementation manner, in order to adapt to the operation of the flexible FPC line, an FPC base 431 for directly carrying the FPC line can also be correspondingly provided on the carrier, as Figure 6 shown. The FPC base can preliminarily limit the FPC line according to the loading area on the carrier, such as by fixing with glue or paraffin that can be applied, so as to further improve the assembly efficiency.

[0052] As an implementation manner, in order to improve the safety and convenience of the welding operation, a welding base 432 can also be correspondingly provided on the carrier, as Figure 7 shown. At this time, the FPC line and the workpiece to be welded can be correspondingly arranged on the welding base 432 according to the loading area. The setting of the welding base 432 can provide protection for other parts such as the carrier to a certain extent or facilitate the uploading of the FPC line and the workpiece.

[0053] As an implementation manner, including but not limited to the above-mentioned fixtures can be used in processing equipment or systems such as laser welding tooling. The laser welding mechanism and the control mechanism for realizing automatic operation, such as an industrial control computer, can all adopt the solutions of the existing technology without affecting the implementation and innovation of the present invention.

[0054] In the working state, the carrier is cooperatively assembled to the base, and a limiting portion, a wire pressing portion, and an upper cover can be sequentially assembled thereon. The matching assembly is accurately positioned by the magnet in the first positioning hole. At this time, the FPC line on the carrier can be additionally pre-fixed on the FPC base, and the welding base can be directly disposed close to the surface of the carrier to form isolation. At this time, the FPC base can be removed or retained. If it is retained, only a vacancy needs to be provided at the corresponding position to meet the requirements of operations such as welding and bending. The jig after combination can then be transferred to the work to perform subsequent operations. After welding and bending are completed, the finished product can be demolded and transferred to carry out subsequent operations.

[0055] The foregoing description of the specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the invention to the precise forms disclosed, and obviously, many modifications and variations are possible in light of the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical applications, so that those skilled in the art can implement and utilize various different exemplary embodiments of the present invention, as well as various different selections and modifications. The scope of the present invention is intended to be defined by the claims and their equivalents.
