[0023] Please refer to Figure 1 This embodiment discloses a FPCA double-sided dispensing method, including steps S100 to S300. It should be noted that the steps in this embodiment are numbered only for the convenience of review and understanding, and do not limit the execution order of the steps. The contents of each step are described in detail below: S100, placing the target workpiece 10 in a manner that the first surface 11 faces the first direction and the second surface 13 faces the second direction, the first surface 11 and the second surface 13 of the target workpiece 10 are two opposite surfaces, the first surface 11 of the target workpiece 10 is provided with a first glue spotting area 12, the second surface 13 of the target workpiece 10 is provided with a second glue spotting area 14, the area between the first glue spotting area 12 and the second glue spotting area 14 on the projection plane of the first surface 11 of the target workpiece 10 is a non-glue spotting area 15, and the first direction and the second direction are two opposite directions on the same straight line; S200, bending and fixing the target workpiece 10 so that the first glue spot area 12 and the second glue spot area 14 are both oriented in the first direction or the second direction; S300, sending the bent and fixed target workpiece 10 into the target glue dispensing area.

[0024] For example, in a new energy power battery, FPCA is used as a signal transfer board, wherein the signal transfer board is usually in a long strip shape, and the electronic components 20 (see Fig. 9 ) to perform glue dispensing to encapsulate and protect the electronic components 20 as a whole or in part. This embodiment takes the signal adapter board as an example of the target workpiece 10. For the current dispensing equipment, the dispensing head of the dispensing equipment is usually arranged along the longitudinal direction, and the movement direction of the dispensing head is up and down. The glue falls from the dispensing head from top to bottom onto the target workpiece 10. Therefore, in this embodiment, the "up" direction is used as an example of the first direction, and the "down" direction is used as an example of the second direction, that is, step S100 places the target workpiece 10 in a manner such that the first side 11 faces upward and the second side 13 faces downward. Unlike ordinary FPCA, the FPCA used as a signal adapter board has a small number of electronic components 20 and their positions are sparsely distributed. Please refer to Figure 2, if the first glue spot area 12 of the first surface 11 and the second glue spot area 14 of the second surface 13 of the target workpiece 10 are projected onto the same plane, for example, on the projection plane of the first surface 11, the first glue spot area 12 and the second glue spot area 14 will not intersect, that is, on the projection plane of the first surface 11 of the target workpiece 10, the area between the first glue spot area 12 and the second glue spot area 14 is a non-glue spot area 15, that is, there is no need to perform glue spotting in this area. Based on the distribution characteristics of the glue spotting areas on different surfaces of the signal adapter board, in this embodiment, the target workpiece 10 is bent and fixed before performing glue spotting, so that the first glue spotting areas 12 and the second glue spotting areas 14 distributed on different surfaces have the same orientation, for example, when the glue spotting head is located above the target workpiece 10, the first glue spotting area 12 and the second glue spotting area 14 are both facing upward; for example, when the glue spotting head is located below the target workpiece 10, the first glue spotting area 12 and the second glue spotting area 14 are both facing downward. Then, the target workpiece 10 is sent into the target glue dispensing area (i.e., the working area of ​​the glue dispensing head). In this way, by bending the target workpiece 10 before glue dispensing, the first glue dispensing area 12 and the second glue dispensing area 14 distributed on the first side 11 and the second side 13 of the target workpiece 10 are both facing the same direction, so that glue dispensing can be performed on both sides of the target workpiece 10 simultaneously, and there is no need to perform glue dispensing on the second side 13 after completing glue dispensing on the first side 11, which is beneficial to improving glue dispensing efficiency and saving the cost of flipping and glue dispensing equipment.

[0025] In some application examples, step S100, bending and fixing the target workpiece 10, may also include: S101 , processing an adhesive layer on the first surface 11 of the target workpiece 10 and at a position adapted to the second adhesive dispensing area 14 .

[0026] For example, the target workpiece 10 is placed flat on a workbench, and double-sided tape or glue is applied to the target area of ​​the first surface 11 of the target workpiece 10 to process the adhesive layer. The target area can be determined based on experience, for example, refer to Figure 2 , bend the target workpiece 10 in advance to observe the position of the second glue spot area 14 of the target workpiece 10 after bending, and then determine the position and size of the target area according to the material of the adhesive layer to ensure the reliability of the adhesion of the bent position of the target workpiece 10, for example Figure 2 The adhesive layer is processed at the position indicated by the mark A, and after the target workpiece 10 is bent, the adhesive layer can stick and fix the bent position of the target workpiece 10. It should be noted that the adhesive layer needs to be removed after the glue dispensing process is completed, so as to obtain a complete target workpiece 10.

[0027] In some other application examples, step S100, bending and fixing the target workpiece 10, may also include: S102 , processing an adhesive layer on the first surface 11 of the target workpiece 10 and at a position adapted to the non-glue-dispensing area 15 , so that the second glue-dispensing area 14 can be covered by the adhesive layer after the target workpiece 10 is bent.

[0028] For example, the principle of the above step S101 is the same, and the adhesive layer can be processed at the non-adhesive area 15 to perform adhesive fixation. Figure 2 and Figure 3 The number of the non-glue dispensing area 15 can be one or more, and the non-glue dispensing area 15 for processing the adhesive layer is usually located adjacent to the glue dispensing area. For example, when the target workpiece 10 is bent, the bending line (such as Figure 3 The first and second glue-dispensing areas 15 (as shown by the mark L1 in the figure) are usually in the non-glue-dispensing area 15, and the second glue-dispensing area 14 is located on one side of the bending line, so that the second glue-dispensing area 14 can be flipped from below the first surface 11 of the target workpiece 10 to above the first surface 11 of the target workpiece 10 after the target workpiece 10 is bent. The adhesive layer is processed in the non-glue-dispensing area 15 where the bending line is located (as shown by the mark B in the figure), and the bending position of the target workpiece 10 can be glued and fixed. Of course, the selection of the non-glue-dispensing area 15 mentioned above is only one of the commonly used examples. In actual applications, the position of the non-glue-dispensing area 15 for processing the adhesive layer can be reasonably selected according to the bending length of the target workpiece 10.

[0029] It is worth mentioning that the first surface 11 of the target workpiece 10 and the position adapted to the second dispensing area 14 and the position of the non-dispensing area 15 of the first surface 11 of the target workpiece 10 (i.e. Figure 2 or Figure 3 The adhesive layer is processed synchronously at the positions indicated by marks A and B in the figure, so that after the target workpiece 10 is bent, the adhesive layers in the glue-dotting area and the non-glue-dotting area 15 can fit each other, thereby improving the reliability of the adhesive fixation of the target workpiece 10 after bending.

[0030] Step S100, bending and fixing the target workpiece 10, including: S110, bending the target workpiece 10 once, or bending the target workpiece 10 multiple times; S120 , fixing the bent target workpiece 10 .

[0031] For example, please refer to Figure 2 Assuming that the second glue spot area 14 is only set on the second surface 13 of the first end of the target workpiece 10, then, it is only necessary to bend the first end of the target workpiece 10 so that the second glue spot area 14 is turned over to the top of the first surface 11 of the target workpiece 10, so that one bending can be achieved; please refer to Figure 3, assuming that the number of the second glue spot areas 14 is two, and the two second glue spot areas 14 are distributed on the second surfaces 13 of the first end and the second end opposite to the target workpiece 10, then the first end and the second end of the target workpiece 10 need to be bent, so that the second glue spot areas 14 at the first end and the second end of the target workpiece 10 are flipped over to the top of the first surface 11 of the target workpiece 10 to achieve secondary bending; also assuming that the number of the first glue spot areas 12 is one, and the number of the second glue spot areas 14 is two, on the projection plane of the first surface 11 of the target workpiece 10, the two second glue spot areas 14 are distributed on the opposite sides of the first glue spot area 12, then the target workpiece 10 can be bent upward (the bending direction is as shown in FIG. Figure 4 As shown by the curved arrow mark in the middle), the first glue spot area 12 and the second glue spot area 14 of the target workpiece 10 are both facing upward, so that secondary bending can be achieved; please refer to Figure 5 , and assuming that the number of the second glue spot areas 14 is two, and the number of the first glue spot areas 12 is also two, two sections of the target workpiece 10 are bent upward, and then one section of the target workpiece 10 is bent upward, so that the first glue spot area 12 and the second glue spot area 14 of the target workpiece 10 are both facing upward, achieving three bends; and so on, when the number of the first glue spot area 12 and the second glue spot area 14 of the target workpiece 10 is multiple, the first glue spot area 12 and the second glue spot area 14 can be bent multiple times by the target workpiece 10 to make the first glue spot area 12 and the second glue spot area 14 have the same orientation, so as to achieve synchronous glue spotting on two relative sides of the target workpiece 10.

[0032] After the target workpiece 10 is bent, two parts that are bent toward each other are formed. A virtual dividing line can be set at the connection between the two parts and named as the bending line. Under ideal conditions, the two parts that are bent toward each other can be regarded as one part (the first part) remaining stationary, and the other part (the second part) rotating around the bending line until it rotates to a preset angle and remains stationary. Generally speaking, under ideal conditions, the plane where the first part is located and the plane where the second part is located after bending are parallel to each other. For ease of understanding, the direction indicated when the rotating part (such as the second part) is rotated to the position corresponding to the stationary state is defined as the bending direction, and for ease of illustration and understanding, the direction line is used to indicate the bending direction in the attached drawings. For further understanding, please refer to Figure 4 , when the target workpiece 10 has a regular outer contour (such as a rectangle), the direction line (such as Figure 4 The side line L2 in FIG. 1 can be regarded as one of the side lines parallel to the outer contour of the target workpiece 10 (such as Figure 4 Alternatively, the direction line may be considered parallel to the center line of the target workpiece 10 (eg, Figure 4 as indicated by L4 in the figure).

[0033] In some application examples, in step S110, the target workpiece 10 is bent multiple times, including: S111, bending the target workpiece 10 multiple times according to a first bending mode, in which two adjacent bending directions are opposite, and the bending line and the direction line of the bending direction are perpendicular to each other; Please refer to Figure 6 For the example in the figure, the bending direction of the first bend points to the left, the direction of the second bend points to the right, and the length of the second bend is shorter than the length of the first bend, the direction of the third bend points to the left again, and the length of the third bend is shorter than the length of the second bend, and so on, multiple bends are implemented to achieve the first glue spotting area 12 and the second glue spotting area 14 are arranged upward. It should be noted that for the sake of convenience of example, the thickness of the target workpiece 10 shown in the figure is relatively thick, but in actual applications, the thickness of the FPCA as the target workpiece 10 is relatively thin, and the height difference after bending is within a controllable range, and double-sided synchronous glue spotting can be performed.

[0034] Alternatively, in some other application examples, in step S110, the target workpiece 10 is bent multiple times, including: S112, bending the target workpiece 10 multiple times according to a second bending mode, wherein in the second bending mode, an angle between a bending line and a direction line of a bending direction is an acute angle or an obtuse angle.

[0035] For example, please refer to Figure 4 The angle between the bending line and the direction line of the bending direction is as follows: Figure 4 As shown by the mark R in . By changing the bending direction, the two parts formed by the target workpiece 10 after bending can be made not to completely overlap, so as to avoid the glue dispensing area on one of the parts. For example, the long strip of the target workpiece 10 is bent into a shape such as "Z", "U" or "V", that is, the angle R can be an acute angle such as 30°, 45° or 60°, or an obtuse angle such as 120°, 135° or 150°.

[0036] Preferably, the target workpiece 10 is bent multiple times, including: the target workpiece 10 is bent multiple times according to a second bending mode, and in the second bending mode, the angle between the bending line and the direction line of the bending direction is 45° or 135°.

[0037] For example, please refer to Figure 7 For the long strip of target workpiece 10, the angle between the bending line and the direction line of the bending direction is 45° or 135°, so that the geometric center lines of the two adjacent parts formed after the target workpiece 10 is bent are perpendicular to each other, so that the target workpiece 10 forms a regular pattern after bending, which is convenient for dispensing processing.

[0038] Please refer to Figure 8 and Fig. 9 The present embodiment also provides a FPCA double-sided dispensing fixture, including a carrier plate 100, a support member 200 and a pressing member 300. The carrier plate 100 is provided with a workpiece accommodating area 101, and the workpiece accommodating area 101 is used to place the target workpiece 10 after bending. In some application examples, the workpiece accommodating area 101 can be provided with a positioning groove 102, and the shape of the positioning groove 102 is adapted to the outer contour of the target workpiece 10, so that the target workpiece 10 can be placed in the workpiece accommodating area 101 through the positioning groove. 10 has a first surface 11 and a second surface 13 relative to each other. The first glue spot area 12 of the first surface 11 and the second glue spot area 14 of the second surface 13 of the target workpiece 10 after bending are both facing away from the carrier plate 100, that is, the first glue spot area 12 and the second glue spot area 14 face upwards, so as to facilitate the glue spot processing. The support member 200 is installed on the carrier plate 100 and its position is adapted to the bending position of the target workpiece 10. The clamping member 300 can abut against the upper end surface of the support member 200 and clamp the bending position of the target workpiece 10. Among them, the clamping member 300 can directly clamp the target workpiece 10, or indirectly clamp the target workpiece 10 through the electronic components 20 installed on the target workpiece 10. The support member 200 has a certain thickness to provide a certain supporting force to the clamping member 300 to prevent the clamping member 300 from applying excessive pressure to the bending position of the target workpiece 10 and damaging the target workpiece 10.

[0039] The FPCA double-sided glue dispensing fixture of this embodiment is applied to the above-mentioned FPCA double-sided glue dispensing method. Before glue dispensing, the target workpiece 10 is bent and clamped and fixed by the clamping member 300 and the supporting member 200, so that the first glue dispensing area 12 and the second glue dispensing area 14 distributed on the first surface 11 and the second surface 13 of the target workpiece 10 are both facing the same direction, so that both sides of the target workpiece 10 can be glued synchronously.

[0040] It should be noted that Figure 8 and Fig. 9 Only an example is shown in which the support member 200 and the clamping member 300 are located at one end of the carrier plate 100. However, in actual applications, the support member 200 and the clamping member 300 can be arranged at opposite ends of the carrier plate 100, such as the left and right ends, or can be arranged in the middle of the carrier plate 100, so as to clamp different bending positions of the target workpiece 10.

[0041] For some application examples, please refer to Figure 8 and Fig. 9The pressing member 300 is hingedly connected to the carrier plate 100 or the support member 200. For example, a hinge 310 is provided on the carrier plate 100, and the pressing member 300 is connected to the pressing member 300 through the hinge 310, so that the hinged connection between the pressing member 300 and the carrier plate 100 can be achieved; for example, when the size of the support member 200 is large, the pressing member 300 is installed on the support member 200 through the hinge 310 or the hinge shaft. The bending position of the target workpiece 10 is placed at the working position of the pressing member 300, and the pressing member 300 is closed, and pressure can be applied to the target workpiece 10 through the pressing member 300.

[0042] Alternatively, in some other application examples (this application example is not shown in the figure), the clamping member 300 is movably connected to the carrier plate 100 or the support member 200 through a guide rod. For example, the carrier plate 100 is installed with the guide rod, and the guide rod and the plane where the carrier plate 100 are located are perpendicular to each other. The clamping member 300 is movably mounted on the guide rod. When pressure needs to be applied to the target workpiece 10, the clamping member 300 slides down along the guide rod and abuts against the target workpiece 10, thereby applying a clamping force to the target workpiece 10. For example, when the size of the support member 200 is large, the guide rod is installed on the support member 200, and the clamping member 300 is movably mounted on the guide rod, which can also apply a clamping force to the target workpiece 10.

[0043] Please refer to Figure 8 and Fig. 9 In order to facilitate the clamping member 300 to continuously apply the clamping force to the target workpiece 10, the support member 200 is provided with a first magnetic member 210, and the clamping member 300 is provided with a second magnetic member 320. The support member 200 and the clamping member 300 are magnetically connected through the first magnetic member 210 and the second magnetic member 320. The magnetic method can facilitate the separation of the clamping member 300 and the support member 200, so as to facilitate the removal and placement of the target workpiece 10. It should be conceivable that the clamping member 300 and the support member 200 or the carrier plate 100 can also be locked and fixed by clamping or by threaded fasteners.

[0044] Please continue to refer to Figure 8 and Fig. 9 The pressing member 300 is provided with a height adapting portion 330, which can abut against the target workpiece 10. For different bending positions, the thickness after bending may be different. For example, the thickness of the bending position where the electronic component 20 is provided and the thickness of the bending position where the electronic component 20 is not provided are different. The height adapting portion 330 is provided on the pressing member 300, which can adapt to the bending positions of different thicknesses to ensure that the bending positions will not be deformed during the dispensing process. The height adapting portion 330 can be a small plate with a certain thickness.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
