Description

Technical Field

[0001] The utility model belongs to the technical field of assembly equipment, in particular to a flip-type semi-automatic FPC assembly machine. Background Art

[0002] Electronic devices are one of the indispensable tools for people's entertainment production. They contain large and small electronic components of different types. Among them, FPC flexible circuits are widely used in the connection between hardware. Usually, a relatively small connector is set at the connection end of FPC for connecting with hardware, such as the connection between the mobile phone motherboard and the camera;

[0003] Since the connection port of PFC is very small, manual alignment assembly is usually adopted in the past, so the production efficiency is low. In order to solve this problem, an automatic assembly machine of FPC and hardware has emerged, such as the Chinese public patent document "CN219767348U, a FPC oblique insertion machine pull-down assembly mechanism". According to paragraph 0019 of its specification, when assembling the backlight, the backlight is first moved to the top of the assembly platform, and then the LCD with FPC is grabbed by a six-axis robot, and the FPC is aligned with the backlight hole. After that, the six-axis robot is controlled to perform oblique insertion and complete the assembly. During the assembly process, the FPC is pulled down by the pull-down component, and the FPC is kept in a taut state as a whole, so that the FPC insertion process is smoother, which greatly improves the assembly efficiency and reduces the labor intensity of the staff;

[0004] Although the technical solution can achieve the goal of improving production efficiency, the overall equipment is large in size and usually needs to be assembled in a fixture. Then the product after assembly is still in the fixture and needs to be taken out externally or manually, which is also a factor affecting production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Please refer to Figure 1-5 ;

[0029] Although the FPC assembly machine described in the utility model requires manual assistance, it can improve efficiency compared with traditional full manual operation under the premise of reducing work intensity; it specifically includes a conveying device 1, and the conveying device 1 in this embodiment can push the parts forward for conveying without a fixture, and can specifically be a transmission conveying method such as a conveyor belt, a positioning component 2 is installed on the conveying device 1, and a top pressing device 3 is installed above the positioning component 2, and a flipping device 4 corresponding to the positioning component 2 is installed on one side of the conveying device 1, and a fixture (not shown) is installed on the upper end surface of the flipping device 4, and a floating pressing component 5 is installed on the lower end surface, and the floating pressing component 5 corresponds to the top pressing device 3;

[0030] It should be noted that the assembly machine described in the present invention is used for installation between FPC and hardware, wherein the hardware may be a motherboard or other pre-assembled hardware.

[0031] In the initial state, the flip device 4 is located outside the conveying device 1. At this time, the jig faces upward and the floating pressing component 5 faces downward. During operation, the FPC is manually placed in the jig. Of course, the acupuncture points in the jig should be adapted to the FPC so that the PFC will not deviate or fall during its movement. At the same time, the parts to be assembled enter the positioning component 2 through the conveying device 1. At this time, the position of the parts to be assembled is adjusted by the positioning component 2 to correspond to the jig. Of course, the positioning component 2 has the function of fixing the parts in addition to the positioning function.

[0032] Then the flipping device 4 drives the jig to rotate 180°, so that the jig faces downward and corresponds to the part to be assembled, or even close to it. In this state, the jig also has the function of pressing and fixing the parts; at this time, the connecting end of the FPC corresponds to the position of the part to be assembled. Preferably, a slot corresponding to the part to be assembled is also provided on the jig. After the jig is flipped, the part enters the slot of the jig, which is more convenient for assembly with the FPC;

[0033] Then the pressing device 3 is activated to apply pressure to the floating pressing assembly 5, causing it to move downward. At this time, the floating pressing assembly 5 passes through the fixture and pushes the FPC out of the acupuncture points of the fixture. At the same time, the floating pressing assembly 5 continues to move downward to press the FPC and the parts tightly, so that the connecting end of the FPC is engaged with the parts to complete the assembly; finally, the flipping device is rotated 4180° to reset. At this time, the assembled parts are still on the conveying device 1. After the positioning assembly 2 is reset, the assembled parts are released from the restrictions and then sent out through the conveying device 1.

[0034] Based on the above implementation mode, manual labor only needs to load the FPC and trigger the switch to start the equipment after loading is completed. There is no need for excessive manual operation steps, which greatly reduces the operator's workload. After assembly is completed, the product will be automatically sent out of the equipment without the assistance of other equipment, which simplifies the structure of the equipment and improves production efficiency.

[0035] One embodiment of the flipping device 4 of the utility model specifically includes a fixed base 41, on which a driving motor 42 and a rotating shaft 43 are respectively installed, the driving motor 42 and the rotating shaft 43 are connected through a synchronous wheel set 44, a flip frame 45 is installed on the rotating shaft 43, a fixture is installed on the upper end surface of the flip frame 45, and a floating pressing component 5 is installed on the lower end surface, the driving motor 42 is linked to the synchronous wheel set 44 to rotate the rotating shaft 43, thereby driving the flip frame 45 to reciprocate.

[0036] The floating pressing assembly 5 is further described, which specifically includes a floating frame 51, on which a pressing portion 52 that can pass through the fixture is installed, and a plurality of springs 53 are installed between the flip frame 45 and the floating frame 51. In this embodiment, the floating frame 51 and the flip frame 45 are movably connected, so that the separation of the two can be restricted and the floating frame 51 can be made movable. In the initial state, the spring 53 is located between the two and applies a thrust, so that the floating frame 51 and the flip frame 45 are in a state of being away from each other, and at this time, the pressing portion 52 does not pass through the fixture;

[0037] During operation, the flip frame 45180° rotates so that the fixture is located above the part, and the floating pressing assembly 5 is located below the pressing device 3. Then the pressing device 3 is actuated to apply pressure to the floating frame 51, and at the same time the spring 53 is compressed to make the floating frame 51 approach the flip frame 45. At the same time, the pressing portion 52 extends into the fixture to push the FPC downward, that is, the FPC approaches the part. Further, the pressing portion 52 applies pressure to the end face of the FPC, so that the FPC is buckled with the part. After completion, the pressing device 3 is reset, the pressure applied to the floating frame 51 is cancelled, and under the action of the spring 53, the floating frame 51 moves away from the flip frame 45, and the pressing portion 52 is pulled out of the fixture.

[0038] In one of the embodiments of the pressing part 52, the pressing part 52 includes a connecting rod 521, one end of the connecting rod 521 is connected to the floating frame 51, and the other end passes through the flip frame 45 to be connected to the pressure head 522, and the pressure head 522 is placed in a groove that can be accommodated in the flip frame 45. The pressure head 522 in this embodiment has a larger bottom area than the connecting rod 521, so that the FPC and parts can be replaced and pressed. In addition, under the action of the spring 53, the floating frame 51 and the flip frame 45 are in a distant state, but the pressure head 522 cannot pass through the flip frame 45, so the floating frame 51 and the flip frame 45 can be flexibly connected.

[0039] Furthermore, a plurality of positioning rods 61 are provided on the floating frame 51, and the positioning rods 61 pass through the flip frame 45. A plurality of positioning blocks 62 are installed on the end surface of the conveying device 1, and the positioning blocks 62 are provided with positioning holes 63 corresponding to the positioning rods 61. When the flip frame 45 is flipped, the positioning rods 61 need to enter the positioning holes 63 before the next step can be performed. If the positioning rods 61 cannot enter the positioning holes 63, the surfaces are not aligned to avoid crushing the parts.

[0040] The present utility model is about one of the implementations of the positioning assembly 2, which specifically includes a cylinder 1 21, a cylinder 22 and a cylinder 3 23;

[0041] The cylinder 1 21 is installed longitudinally, and a horizontally arranged cylinder 4 25 is installed at its output end through a connecting piece 24. The placement position of the cylinder 4 25 is consistent with the movement direction of the conveying device 1. A clamping piece 1 261 is installed at the output end of the cylinder 4 25. The clamping piece 1 261 in this embodiment has a clamping groove 1 262.

[0042] The second cylinder 22 is installed longitudinally, and a second clamping piece 271 is installed at its output end. The second clamping piece 271 corresponds to the first clamping piece 261. It should be noted that the fourth cylinder 25 and the first clamping piece 261 are located at the conveying device 1, and the second clamping piece 271 needs to be used in conjunction with the first clamping piece 261. Therefore, the second clamping piece 271 should extend to the conveying device 1, and the second clamping piece 271 is also provided with a second clamping groove 272.

[0043] The cylinder three 23 is horizontally arranged on one side of the conveying device 1, and is distributed at 90 degrees with the cylinder four 25, and a top block 28 is installed at its output end, and the top block 28 corresponds to the other side of the conveying device 1;

[0044] In the initial state, cylinder four 25 and clamping part two 271 are both located above the conveying device 1, which can avoid obstruction in the transportation of parts. When the parts are transported between cylinder four 25 and clamping part two 271, cylinder one 21 and cylinder two 22 are actuated to make cylinder four 25 and clamping part two 271 descend and approach the conveying device 1. At this time, the conveying device 1 stops moving, and then cylinder three 23 is actuated to move the top block 28 toward the other side of the conveying device 1. During this process, the top block 28 contacts the parts and pushes the parts to move laterally to the other side of the conveying device 1 and achieve alignment. Then cylinder four 25 is actuated to push clamping part one 261 to move along the transportation direction of the conveying device 1, and while achieving the clamping connection between the clamping slot one 262 and the parts, it pushes the parts to move toward the direction of clamping part two 271, and finally the other end of the part is clamped with the clamping slot two 272, and the positioning and fixation of the parts are completed.

[0045] After the parts and FPC are assembled, cylinder three 23 drives the top block 28 to reset, and cylinder one 21 and cylinder two 22 respectively drive cylinder four 25 and clamping part two 271 to rise, thereby releasing the restrictions on the parts. It should be noted that the clamping part two 271 fixes the parts in a horizontal manner, which can be understood as the clamping groove two 272 facing downward, and enters the clamping groove two 272 under the push of the clamping part one 261. When the clamping part two 271 rises, the restrictions on the parts are naturally released. Finally, the conveying device 1 is started again to push the assembled parts out of the equipment.

[0046] One embodiment of the top pressing device 3 of the utility model specifically includes a mounting seat 31, a multi-axis moving assembly 32 is mounted on the mounting seat 31, a movable frame 33 is mounted on the output end of the multi-axis moving assembly 32, and a second pressing head 34 corresponding to the floating frame 51 is mounted on the lower end of the movable frame 33. The movable frame 33 is driven downward by the multi-axis moving assembly 32, so that the second pressing head 34 contacts the floating frame 51 and applies pressure;

[0047] Furthermore, a fixed frame 35 is installed on the multi-axis moving component 32. The fixed frame 35 is in an "H" shape and can strengthen the overall structure. Its two sides are respectively slidably connected to the movable frame 33. A visual camera 36 is installed at the lower end of the fixed frame 35. It should be noted that the fixed frame 35 cannot move up and down, so the visual camera 36 can be kept at a fixed distance from the conveying device 1. As long as the focus is adjusted, there will be no blur. After the top pressing operation is completed, the flip frame 45 drives the fixture to reset. At this time, the assembled product is not obstructed, and the multi-movable fixed frame 35 can be moved horizontally by the multi-axis moving component 32, and the product can be visually inspected by the visual camera 36.
