DETAILED DESCRIPTION

[0043] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments are not limiting to the scope of the present application unless otherwise specifically stated.

[0044] The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the scope of the application, its application, or uses.

[0045] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered as if the techniques, methods, and apparatus were discussed in detail herein, where appropriate.

[0046] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary, and not as a limitation. Thus, other examples of exemplary embodiments can have different values.

[0047] It should be noted that like references and characters herein relate to like items throughout the figures, and once an item is defined in one figure, it need not be discussed further in subsequent figures.

[0048] According to one embodiment of the present application, a FPC bending method is provided. As shown in Figures 1 to 3 The FPC bending method includes:

[0049] S100, bending a first bending part of the FPC board along the X axis. For example, the first bending part 21 of the FPC board 20 can be bent along the X axis by the first bending piece 11. That is, the first bending piece 11 pushes one end or root of the first bending part 21 to rotate around the X axis, thereby achieving the effect of bending along the X axis.

[0050] As shown in Figure 3 , the FPC board 20 is a board that has not been bent, and the first bending part 21 in the first FPC board 20-1 is a structure after the FPC board 20 is bent by the first bending piece 11. The first bending part 21 can be a gold finger of the FPC board 20. The first bending piece 11 can move along the Z axis direction and push the first bending part 21 to bend along the X axis, for example, drive the first bending part 21 to rotate downward along the X axis. Wherein, the first bending part 21 can rotate 90° or close to 90° along the X axis, or other angles, which can be determined by those skilled in the art according to the actual situation, which is not limited here.

[0051] S200, bending a second bending part of the FPC board along the Y axis, so that the second bending part 22 and the first bending part 21 are located on the same side of the main body 23. For example, the second bending part 22 of the FPC board 20 can be bent along the Y axis by the second bending piece 12. That is, the second bending piece 12 pushes one end or root of the second bending part 22 to rotate around the Y axis, thereby achieving the effect of bending along the Y axis.

[0052] Wherein, the second bending part 22 and the first bending part 21 are located on the same side of the main body 23. For example, the FPC board 20 is placed horizontally, the second bending part rotates downward around the Y axis, the second bending part 22 is bent to the lower side of the main body 23, the first bending part 21 rotates downward around the X axis, and the first bending part 21 is also bent to the lower side of the main body 23.

[0053] As shown in Figure 3 , the second bending part 22 in the first FPC board 20-1 is a structure after the FPC board 20 is bent by the second bending piece 12. The second bending part 22 can be an electrical connection part of the FPC board 20 to the product. The second bending piece 12 can move along the Z axis, thereby being able to push the second bending part 22 to bend along the Y axis. For example, drive the second bending part 22 to rotate downward along the Y axis. Wherein, the second bending part 22 can rotate 30°, 45° or 60° along the Y axis, so as to enable the FPC board 20 to avoid the structure in the product during assembly. Of course, as for the specific bending angle, those skilled in the art can determine it according to the actual situation, which is not limited here.

[0054] It should be noted that when the FPC board 20 has multiple second bending portions 22, the second bending member 12 can be provided with multiple bending portions, and each of the multiple bending portions corresponds one-to-one with a second bending portion 22. Multiple bending portions can simultaneously perform bending operations on multiple second bending portions 22.

[0055] S300: The second bent portion of the FPC board is bent along the X-axis, and then the second bent portion of the FPC board is bent along the Z-axis, so that the portion of the second bent portion after the Z-axis bend is parallel to the first bent portion. For example, the second bent portion 22 after the second bent portion 12 is bent can be further bent using a third bending member. That is, the third bending member can drive... Figure 3 One end or root of the second bending section 22 of the first FPC board 20-1 first rotates about the X-axis and then about the Z-axis to achieve the bending operation.

[0056] In this process, the third bending member first causes the second bending portion 22 to bend along the X-axis, for example, by rotating the second bending portion 22 upwards along the X-axis at a certain angle, thereby avoiding other structures in the product. Then, the third bending member causes the second bending portion 22 to bend along the Z-axis, thereby connecting the second bending portion 22 to the corresponding position on the product. The specific angle of rotation of the second bending portion 22 can be determined by those skilled in the art based on actual conditions, and is not specifically limited here.

[0057] In this example, the second bend 22 is arranged parallel to the first bend 21, and the second bend 22 extends along the Z-axis. For example, the second bend 22 and the first bend 21 can be a plate body. The second bend of the FPC plate is bent along the Z-axis to a certain angle so that the second bend 22 is parallel to the first bend 21, and the length or width direction of the second bend 22 extends along the Z-axis.

[0058] In this example, the third bending component can be composed of a four-axis robotic arm 71 and a first gripper 72. The robotic arm 71 is connected to the first gripper 72, which can clamp the second bending portion 22. Then, under the drive of the robotic arm 71, it can perform a precise multi-axis bending operation. The first gripper 72 can be an electric gripper.

[0059] In this example, during the assembly of the FPC board 20, multiple bending components sequentially bend the first bend and the second bend 22 on the FPC board 20 in different directions, which can improve the bending accuracy and the assembly efficiency of the FPC board 20.

[0060] In one example, the folding the second bending part 22 of the FPC board 20 along the X axis, and then folding the second bending part 22 of the FPC board 20 along the Z axis further comprises: folding the second bending part 22 of the FPC board 20 along the Y axis.

[0061] As shown in FIG. 3, the folding step of the FPC board 20 comprises: Figure 3

[0062] S310, folding the second bending part 22 of the FPC board 20 along the X axis.

[0063] S320, folding the second bending part 22 of the FPC board 20 along the Z axis.

[0064] S330, folding the second bending part 22 of the FPC board 20 along the Y axis. That is, the third bending member can first drive the second bending part 22 of the first FPC board 20-1 to fold along the X axis, for example, drive the second bending part 22 to rotate a certain angle along the X axis upward, so as to avoid other structures in the product. Then the third bending member drives the second bending part 22 to fold along the Z axis, so that the plane where the second bending part 22 is located is perpendicular to the plane composed of the X axis and the Y axis, that is, it can be parallel to the first bending part 21 and can correspond to the mounting part position on the product.

[0065] Since the third bending member needs to avoid the structure of the product during the folding process of the second bending part 22, after folding the second bending part 22 of the FPC board 20 along the Z axis, the second bending part 22 may be skewed. At this time, by folding the second bending part 22 of the FPC board 20 along the Y axis, the position of the second bending part 22 can be further adjusted so that the second bending part 22 can extend along the Z axis. Then the third bending member folds the second bending part 22 along the Y axis, for example, folds along the Y axis upward, so as to fold into Figure 3 the structure of the second bending part 22 of the third FPC board 20-3 in FIG. 3. Thus, the second bending part 22 can be connected to the mounting part position of the product. The specific angle of rotation of the second bending part 22 can be determined by those skilled in the art according to the actual situation, and is not limited here.

[0066] In this example, the third bending member first drives the second bending part 22 of the first FPC board 20-1 to fold along the X axis, so as to avoid other structures in the product. As shown in FIG. 3, Figure 3 ​In the process, the first FPC plate 20-1 is the shape formed by bending the FPC plate 20 under the action of the first bending mechanism 1. The second FPC plate 20-2 is the partial bending process of the second bent portion 22 under the action of the second bending mechanism 7. The second bent portion 22 of the third FPC plate 20-3 is the shape formed by bending under the action of the second bending mechanism 7. Then, the robotic arm 71 can simultaneously drive the first gripper to rotate along the Z-axis and Y-axis, thereby bending the second bent portion 22 with an arc-shaped motion trajectory to... Figure 3 The structure of the second bend 22 of the third FPC board 20-3.

[0067] In one example, prior to the step of bending the first bent portion of the FPC board along the X-axis, the FPC bending method further includes positioning the FPC board 20.

[0068] In this example, the material is picked up by a material-picking component, for example, by adsorption. After picking up the material, the FPC board 20 is conveyed to a preset position, and then bent by the first bending component 11 and the second bending component 12. Before picking up the material, the FPC board 20 can be positioned, which helps to improve the bending accuracy and assembly accuracy of the FPC board 20.

[0069] In one example, positioning the FPC board 20 includes placing the FPC board 20 on the positioning plate 3 to position the FPC board 20.

[0070] like Figure 13 As shown, the positioning plate 3 is provided with multiple positioning posts, and the FPC board 20 is placed on the positioning plate 3. The positioning posts can pass through the FPC board 20. The multiple positioning posts work together to position the FPC board 20. The positioning plate 3 is also provided with negative pressure holes, which can hold the FPC board 20 in place and prevent the FPC board 20 from shifting.

[0071] In one example, after positioning the FPC board, the FPC bending method further includes: conveying the FPC board to a first assembly position.

[0072] In this example, after the FPC board 20 is positioned, the first bending mechanism 1 picks up the FPC board 20 and transports it to the first assembly position. At the first assembly position, the first bending member 11 and the second bending member 12 bend the FPC board 20 and assemble the FPC board 20 into the product.

[0073] In one example, the plurality of FPC boards are bent, the plurality of FPC boards are arranged along the Y axis at intervals, and the plurality of FPC boards have a height difference in the Z axis direction. The plurality of FPC boards 20 can be bent at the same time, thereby improving work efficiency. The plurality of FPC boards 20 have a height difference in the Z axis direction, thereby avoiding interference.

[0074] In this example, the first bending member 11 is arranged at intervals, the plurality of first bending members 11 have a height difference in the Z axis direction, and the plurality of first bending members 11 can bend the plurality of FPC boards 20, respectively; and / or,

[0075] The second bending member 12 is arranged at intervals, the plurality of second bending members 12 have a height difference in the Z axis direction, and the plurality of second bending members 12 can bend the plurality of FPC boards 20, respectively.

[0076] In this example, the first bending member 11 is arranged at intervals, the plurality of first bending members 11 have a height difference in the Z axis direction, and the plurality of first bending members 11 can bend the plurality of FPC boards 20, respectively; and / or,

[0077] For example, the first bending member 11 can be arranged at intervals along the Y axis, and the two first bending members 11 have a height difference in the Z axis direction.

[0078] In this example, the second bending member 12 can also be arranged at intervals, thereby enabling the plurality of FPC boards 20 to be bent respectively, thereby improving work efficiency. The plurality of second bending members 12 have a height difference in the Z axis direction, thereby avoiding interference. The number of first bending members 11 and second bending members 12 can be the same, thereby enabling the first bending portion 21 and the second bending portion 22 of the plurality of FPC boards 20 to be bent.

[0079] For example, the second bending member 12 can be arranged at intervals along the Y axis, and the two second bending members 12 have a height difference in the Z axis direction.

[0080] In one example, before the second bending portion 22 of the FPC board 20 is bent along the X axis, the method further comprises assembling the FPC board 20 into a product.

[0081] In this example, the first bending member 11 and the second bending member 12 bend the FPC board 20, and then the FPC board 20 is assembled into a product. Then the third bending member further bends the second bending portion 22.

[0082] In this example, the first bending member 11 and the second bending member 12 can push the first bending part 21 and the second bending part 22 to bend, and keep the first bending part 21 and the second bending part 22 in the bent state, and then the first bending member 11 and the first bending part 21 are inserted into the product together. The second bending member 12 and the second bending part 22 are inserted into the product together, and the first bending part 21 and the second bending part 22 are fixed in the product, so that the first bending part 21 and the second bending part 22 can be smoothly installed in the product, and the bending accuracy and assembly accuracy of the FPC board 20 can be ensured. After the plate body of the FPC board 20 is installed to the product, the first bending member 11 and the second bending member 12 are pulled out of the product.

[0083] Alternatively, the plate body of the FPC board 20 can be installed to the product first, and then the first bending member 11 and the second bending member 12 push the first bending part 21 and the second bending part 22 to bend into the product, and fix the first bending part 21 and the second bending part 22 in the product.

[0084] In one example, the assembly of the FPC board 20 to the product includes pressing the FPC board 20 into the product.

[0085] As shown in Figure 8 In this example, the plate body of the FPC board 20 can be pressed into the product by the pressing member 14. The pressing member 14 can move along the Z-axis direction to press the FPC board 20 into the product, so as to assemble the FPC board 20 to the product. For example, the plate body of the FPC board 20 is pressed to the product by the pressing member 14, so that the buckle on the product can buckle the FPC board 20.

[0086] In one example, before the assembly of the FPC board 20 to the product, the method further includes collecting the actual position of the product, and adjusting the product to the preset position.

[0087] As shown in Figure 5 and Figure 6 In this example, the product is carried on the first assembly table 4, and the vision camera 5 is located on one side of the first assembly table 4. The vision camera 5 can take a photo of the product on the first assembly table 4 to collect the actual position of the product, and the vision camera 5 can guide the assembly of the FPC board 20.

[0088] The first assembly table 4 can be movably arranged, and the vision camera 5 can take a photo of the product on the first assembly table 4, so as to determine the position of the product. When the product deviates, the first assembly table 4 can be rotated to drive the product to rotate, so as to drive the product to adjust the position. The first assembly table 4 can be driven to rotate by a rotating driving device, for example, a motor.

[0089] In this example, one side of the visual camera 5 is also provided with a matched light source, which can be driven by a pneumatic cylinder to adjust the position, so as to better illuminate the product. After the position of the product is adjusted, the pneumatic cylinder drives the light source to move away to avoid other structures.

[0090] In one example, after the FPC plate is assembled to the product, the method further comprises:

[0091] The product is transported to a second assembly position, then the second bending part of the FPC plate is bent along the X axis, and then the second bending part of the FPC plate is bent along the Z axis.

[0092] In this example, the first bending part 21 of the FPC plate 20 is bent along the X axis and the second bending part 22 of the FPC plate 20 is bent along the Y axis at the first assembly position. The second bending part 22 of the FPC plate 20 is bent along the X axis, and then the second bending part 22 of the FPC plate 20 is bent along the Z axis at the second assembly position. That is, the first bending member 11 and the second bending member 12 are located in the same process, and the third bending member is located in another process. The product can be transported to the second assembly position, i.e., the process where the third bending member is located, by a conveying mechanism. The first bending member 11 and the second bending member 12 bend the first bending part 21 and the second bending part 22 of the FPC plate 20, respectively, and the FPC plate 20 is assembled to the product. Then the product is transported to the position of the third bending member by the conveying mechanism, and the second bending part 22 is further bent by the third bending member. The third bending member is arranged separately from the first bending member 11 and the second bending member 12, which can modularize the structure of the first bending member 11, the second bending member 12 and the third bending member, and is beneficial to the assembly and maintenance of each structure.

[0093] The conveying mechanism can be a conveying belt, a robot hand, or a combination of different types of conveying mechanisms, etc. Those skilled in the art can determine according to the actual situation, which is not limited here.

[0094] In one example, the method further comprises: transporting a plurality of products to the second assembly position, and sequentially bending the second bending part 22 of the FPC plate 20 of the plurality of products. That is, a plurality of products are transported to the position of the third bending member, and the third bending member can move between the plurality of products, so as to sequentially bend the FPC plate 20 on the plurality of products.

[0095] As Figures 9 to 11As shown, in this example, the third bending member includes a mechanical arm 71 and a first clamping jaw 72, the mechanical arm 71 is connected to the first clamping jaw 72, the first clamping jaw 72 can clamp the second bending part 22, and then can accurately perform multi-axis bending operation under the driving of the mechanical arm 71. The outer periphery of the third bending member is provided with a plurality of second assembly tables 73, and the products can be carried on the second assembly tables 73.

[0096] In this example, the third bending member can move between a plurality of products to bend the FPC board 20 of the products on different second assembly tables 73. Among them, when the third bending member bends the FPC board 20 of the product on one of the second assembly tables 73, the remaining second assembly tables 73 can be used as a standby table to improve the utilization rate of the third bending member, thereby facilitating the improvement of work efficiency.

[0097] For example, two second assembly tables 73 are provided, and the two second assembly tables 73 are respectively in transmission connection with the X-axis cylinder and the Y-axis cylinder. Among them, one end of the X-axis cylinder along the X-axis is the feeding position, and one end of the Y-axis cylinder along the Y-axis is the feeding position. The X-axis cylinder and the Y-axis cylinder alternately take materials, and both of them bend and assemble the FPC board 20 at the end away from the feeding position, so as to avoid interference with the third bending member.

[0098] According to the second aspect of the present application, an FPC bending device is provided. The FPC bending device can perform the FPC bending method described in the above embodiments.

[0099] As shown in the figure, Figures 4 to 8 In this example, the FPC bending device includes a first bending mechanism 1. The first bending mechanism 1 includes a suction member, a first bending member 11 and a second bending member 12, the suction member is suitable for adsorbing the FPC board 20, the first bending member 11 can be arranged in the suction member, the first bending member 11 can move along the Z-axis to push the first bending part 21 of the FPC board 20 to bend along the X-axis, and the second bending member 12 can be arranged in the suction member, the second bending member 12 can move along the Z-axis to push the second bending part 22 of the FPC board 20 to bend along the Y-axis.

[0100] As shown in the figure, Figure 8As shown, in this example, the first bending member 11 can be a plate structure, which can be driven to move along the Z-axis by the second driving member 111. The first bending portion 21 can be the gold fingers of the FPC board 20. The FPC board 20 is an unbent board, and the first FPC board 20-1 is the structure of the FPC board 20 after being bent by the first bending mechanism 1. The adsorption member adsorbs the FPC board 20, and then the second driving member 111 drives the first bending member 11 to move toward the first bending portion 21, pass through the adsorption member, and push the first bending portion 21 to bend along the X-axis. For example, the first bending portion 21 can rotate 90° or close to 90° along the X-axis. Those skilled in the art can determine this according to the actual situation, and no specific limitation is made here.

[0101] like Figure 8 As shown, in this example, the second bending member 12 can be a plate structure, and it can have multiple bends corresponding to the second bending portion 22 of the FPC board 20. The second bending portion 22 is the electrical connection portion of the FPC board 20 to the product. The third driving member 121 can drive the second bending member 12 to move along the Z-axis, thereby pushing the second bending portion 22 to bend along the Y-axis. For example, the second bending portion 22 can rotate 30°, 45°, or 60° along the Y-axis, etc., which can be determined by those skilled in the art according to the actual situation, and is not specifically limited here.

[0102] It should be noted that the second driving component 111 can be a cylinder or a linear motor or other driving device. Those skilled in the art can determine the specific type of device based on the actual situation, and no specific limitation is made here.

[0103] like Figure 7 and Figure 8 As shown, in this example, the first bending mechanism 1 further includes a mounting plate 13, on which the first driving member 2 and the second driving member 111 are mounted. One end of the mounting plate 13 along the Z-axis is provided with a suction nozzle or suction plate to form an adsorption member. The mounting plate 13 has a through-hole 131 along the Z-axis, through which the first bending member 11 can pass. The mounting plate 13 also has a corresponding perforation for clearance at the position of the second bending member 12.

[0104] like Figure 8 As shown, in one example, the first bending mechanism 1 further includes a pressing member 14, which can be inserted through the adsorption member and can press the FPC board 20 into the product.

[0105] In this process, the first bending member 11 pushes the first bending portion 21 to maintain the bend, and the second bending member 12 pushes the second bending portion 22 to maintain the bend. Then, the first bending mechanism 1 can move towards the product, and the first bending member 11 and the first bending portion 21 are inserted into the product together, and the second bending member 12 and the second bending portion 22 are inserted into the product together, so that the first bending portion and the second bending portion 22 can be smoothly installed into the product. Then, the first bending member 11 and the second bending member 12 are pulled out of the product. Then, the lower pressing member 14 presses the FPC board 20 tightly against the product, so that the buckles on the product can fasten the FPC board 20.

[0106] Alternatively, the pressing member 14 can press the FPC board 20 firmly against the product, allowing the clips on the product to hold the FPC board 20 in place. Then, the first bending member 11 and the second bending member 12 respectively push the first bending portion 21 and the second bending portion 22 to bend and fix them inside the product. Those skilled in the art can determine the specific method according to the actual situation, and no specific limitation is made here.

[0107] like Figure 5 As shown, in this example, the lower pressure member 14 includes a pressure plate 141 and a plurality of pressure rods 142, the plurality of pressure rods 142 being mounted on the pressure plate 141, and the pressure rods 142 being adapted to abut against the FPC plate 20.

[0108] In this example, multiple pressure rods 142 are connected to the pressure plate 141 at intervals, and the pressure rods 142 can pass through the mounting plate 13. The pressure plate 141 can simultaneously drive the multiple pressure rods 142 to press down the FPC board 20, thereby making the force on the FPC board 20 more even, so as to smoothly press the FPC board 20 into the product.

[0109] In this example, the fourth drive member 144 can drive the pressure plate 141 to move along the Z-axis, thereby simultaneously driving multiple pressure rods 142 to press down the FPC plate 20. The fourth drive member 144 can be fixedly mounted on the mounting plate 13.

[0110] like Figure 8 As shown, in this example, the pressure head of the pressure bar 142 can be a circular structure or a square structure, etc., which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0111] It should be noted that the fourth driving component 144 can be a cylinder or a linear motor or other driving device. Those skilled in the art can determine the specific type of device based on the actual situation, and no specific limitation is made here.

[0112] like Figure 8 As shown, in one example, the pressure rod 142 is movably connected to the pressure plate 141, and an elastic element 143 is provided between the pressure rod 142 and the pressure plate 141.

[0113] In this example, the pressing rod 142 can be movably arranged in the pressing plate 141, the elastic member 143 can be a cylindrical spring, the elastic member 143 can be sleeved on the pressing rod 142, one end of the spring abuts against the pressing rod 142, and the other end abuts against the pressing plate 141. When the pressing rod 142 presses the FPC plate 20, the elastic member 143 can be contracted to play a buffering effect, so as to avoid that the FPC plate 20 is damaged by the pressing rod 142.

[0114] As shown in Figure 6 and Figure 7 , in one example, two first bending mechanisms 1 are arranged at intervals, and the two first bending mechanisms 1 have a height difference in the Z-axis direction.

[0115] In this example, the two first bending mechanisms 1 can be arranged at intervals along the Y-axis direction. By arranging two first bending mechanisms 1, two FPC plates 20 can be bent at the same time, so as to facilitate improving work efficiency. The two first bending mechanisms 1 have a height difference in the Z-axis direction, and the two first bending mechanisms 1 can avoid interfering with each other.

[0116] As shown in Figure 7 and Figure 8 , in one example, the FPC bending device further comprises two first driving members 2, and the two first driving members 2 can drive the two first bending mechanisms 1 to move in the Z-axis direction, respectively.

[0117] In this example, the mounting plate 13 can be mounted on the mounting bracket 15, and the first driving member 2 is drivingly connected to the mounting bracket 15, so that the first driving member 2 can drive the first bending mechanism 1 to move along the Z-axis. When assembling the FPC plate 20, the product is located below the first bending mechanism 1, and the first driving member 2 can drive the first bending mechanism 1 to move downward, so as to facilitate assembling the FPC plate 20. After assembly is completed, the first driving member 2 can drive the first bending mechanism 1 to move upward, so as to move away from the product, so as to facilitate the product to enter the next process.

[0118] The mounting bracket 15 can be assembled by a plurality of rod bodies and plate bodies, and the specific structure of the mounting bracket 15 can be determined by those skilled in the art according to the actual situation, which is not limited here.

[0119] In this example, by arranging two first driving members 2 to drive two first bending mechanisms 1 respectively, the flexibility of the structure can be improved. That is, the FPC plate 20 on one of the first bending mechanisms 1 can be assembled first, and then the FPC plate 20 on the other first bending mechanism 1 can be assembled. Alternatively, two FPC plates 20 can be assembled at the same time, which can be determined by those skilled in the art according to the actual situation, which is not limited here.

[0120] It should be noted that the first driving member 2 can be a driving device such as a cylinder or a linear motor, and the person skilled in the art can determine according to the actual situation, which is not specifically limited here.

[0121] As shown in Figure 6 and Figure 13 , in one example, the FPC bending device further comprises a positioning plate 3 and a first assembly table 4, the positioning plate 3 is suitable for placing the FPC plate 20 to position the FPC plate 20, and the first assembly table 4 is suitable for carrying products, and the first bending mechanism 1 can move between the positioning plate 3 and the first assembly table 4.

[0122] As shown in Figure 4 , in this example, the FPC bending device further comprises a hopper 9, and the FPC plate 20 is placed in the hopper 9. The hopper 9 can be manually loaded. The suction cup can suck the FPC plate 20 in the hopper 9 and then place it on the positioning plate 3. The positioning plate 3 can position the FPC plate 20. The first bending mechanism 1 can adsorb the FPC plate 20 on the positioning plate 3, then move to the position of the first assembly table 4, and then assemble. By positioning the FPC plate 20 through the positioning plate 3, the assembly precision can be improved.

[0123] In this example, a plurality of positioning columns are provided on the positioning plate 3, and the positioning columns are provided through the FPC plate 20, so as to play a positioning role on the FPC plate 20. The positioning plate 3 is also provided with a negative pressure hole, and the FPC plate 20 can be adsorbed through the negative pressure hole to avoid the FPC plate 20 from deviating.

[0124] As shown in Figure 12 , in this example, the fifth driving member 10 can drive the first bending mechanism 1 to move along the Y-axis direction, so as to move between the positioning plate 3 and the first assembly table 4. The fifth driving member 10 can be a double-acting linear motor, which can drive the suction cup to take materials and also drive the first bending mechanism 1 to move along the Y-axis direction. Thus, the space can be saved, and the compactness of the structure can be improved.

[0125] It should be noted that one of the fifth driving members 10 is drivingly connected to the cylinder, and the cylinder is drivingly connected to the first driving member 2 through the support plate, so that the cylinder can drive the first bending mechanism 1 to move along the X-axis direction. Among them, the two first driving members 2 are connected to the support plate, and the cylinder is drivingly connected to the support plate. The cylinder can synchronously drive the two first bending mechanisms 1.

[0126] It should be noted that the other mover of the fifth driving member 10 is drivingly connected to the suction disc through the X-axis cylinder and the Z-axis cylinder. That is, the mover of the fifth driving member 10 is drivingly connected to the X-axis cylinder, the X-axis cylinder is drivingly connected to the Z-axis cylinder, and the Z-axis cylinder is drivingly connected to the suction disc. After the suction disc is moved to the material taking position by the fifth driving member 10, the X-axis cylinder drives the Z-axis cylinder to move to a preset position along the X-axis direction, and then the Z-axis cylinder drives the suction disc to move downward along the Z-axis direction, so that the suction disc can suck the FPC plate 20 in the material bin 9. Then the X-axis cylinder and the Z-axis cylinder are reversely operated. The fifth driving member 10 drives the suction disc to the positioning plate 3 again, and the FPC plate 20 on the suction disc can be placed on the positioning plate 3 through the X-axis cylinder and the Z-axis cylinder.

[0127] As shown in Figure 5 In one example, the FPC bending device further comprises a vision camera 5 located on one side of the first assembly table 4, the vision camera 5 can take a photo of the product on the first assembly table 4, the first assembly table 4 is movably arranged, and the first assembly table 4 can drive the product to adjust the position.

[0128] In this example, the vision camera 5 can guide the assembly of the FPC plate 20. The vision camera 5 can take a photo of the product on the first assembly table 4, so as to determine the position of the product. When the product deviates, the first assembly table 4 can be rotated to drive the product to rotate, thereby adjusting the position of the product. The first assembly table 4 can be driven to rotate by a rotating driving device, for example, the rotating driving device can be a motor.

[0129] In this example, the FPC bending device further comprises a light source cooperating with the vision camera 5. The light source can be driven by a cylinder to adjust the position, so as to better illuminate the product. After the position of the product is adjusted, the cylinder drives the light source to move away to avoid the first bending mechanism 1.

[0130] As shown in Figure 6 In one example, the FPC bending device further comprises a baffle 6 located on at least one side of the first assembly table 4.

[0131] In this example, the product is fixed in the flow tooling, and the flow tooling is conveyed to the first assembly station 4 by the conveying belt. The conveying belt can be composed of two belts, and the first assembly station 4 is located between the two belts. When feeding, the baffle 6 located in front of the first assembly station 4 moves upward under the action of the air cylinder along the conveying direction of the conveying belt, and can block the flow tooling on the first assembly station 4. Then a positioning pin is inserted into the flow tooling through an air cylinder to further fix the flow tooling. After the flow tooling enters the first assembly station 4, the baffle 6 located at the rear side of the first assembly station 4 moves upward under the action of the air cylinder along the conveying direction of the conveying belt, and can block the flow tooling behind. After the FPC board 20 is assembled, the baffle 6 moves downward, and the positioning pin is extracted from the flow tooling, so as to facilitate the flow of the flow tooling to the next process.

[0132] As shown in Figure 3 In one example, two positioning plates 3 are arranged at intervals, and the two positioning plates 3 have a height difference in the Z-axis direction.

[0133] In this example, the positioning plates 3 are arranged at intervals along the Y-axis direction, and the two positioning plates 3 have a height difference in the Z-axis direction, so as to facilitate the two first bending mechanisms 1 to take materials and avoid interference.

[0134] It should be noted that one of the positioning plates 3 is drivingly connected with an air cylinder, and the air cylinder drives one of the positioning plates 3 to move along the Z-axis relative to the other, so as to generate a height difference. For example, after the suction cup finishes discharging, the air cylinder drives the positioning plate 3 to move along the Z-axis to generate a height difference. After the first bending mechanism 1 finishes taking materials, the air cylinder drives the positioning plate 3 to move along the Z-axis, so that the two positioning plates 3 are located in the same plane, so as to facilitate the suction cup to discharge.

The X-axis cylinder and the Y-axis cylinder alternately take materials, and both of them bend and assemble the FPC board 20 at the end away from the feeding position.
