[0030] The utility model will be further explained in detail in combination with specific embodiments.

[0031] Embodiment:

[0032] As Figure 1 and Figure 2 The utility model discloses a PCBA / FPC flexible production full-automatic line body 100, including machine 1, vision detection work station 2a, spray flux work station 3a, welding work station 3b, function detection work station 3c, gel work station 3d and UV curing device 4 are sequentially set on the machine along X direction, every work station (vision detection work station 2a, spray flux work station 3a, welding work station 3b, function detection work station 3c, gel work station 3d) includes A flow line 5, B flow line 6 and a function device, A flow line 5 and B flow line 6 all along X direction conveying product fixture 200, the lower of function device is work position, and the Y direction side of work position is conveying position, A flow line 5 switches position between work position and conveying position, when A flow line 5 is located in conveying position, and B flow line 6 is butt joint.

[0033] The functional devices on each station are different, such as the functional device on the visual inspection station 2a is a visual inspection device, the functional device on the welding station 3b is a welding device, and so on. The PCBA / FPC takes the product fixture 200 as a carrier and moves through the alternately arranged A flow line 5 and B flow line 6. The product fixture 200 carrying the PCBA / FPC sequentially undergoes visual inspection, flux spraying, HB (hot-pressing soldering) welding, conductive function detection, point sealant, and UV (ultraviolet) curing to complete production. The A flow line 5 is responsible for moving the product fixture 200 in position to the working position, so that the corresponding functional device completes its process on the PCBA / FPC. Subsequently, the A flow line 5 sends the product fixture 200 back to the conveying position and then continues to move along the X direction. The B flow line 6 serves as a buffer component between adjacent two stations, so that the front and rear product fixtures 200 do not need to always maintain synchronous conveying. By controlling the start and stop procedures of the A flow line 5 and the B flow line 6, the conveying rhythm can be rationalized. The modularization of the stations on the assembly line makes the assembly line flexible and can be built. The conveying is convenient through the alternately arranged AB flow lines, which saves the handling time, so the work efficiency is high. The production line only needs to leave the operators for loading and unloading, and does not need to have an operator corresponding to each station, so the total manpower is saved, and the labor cost is greatly reduced.

[0034] As shown in Figure 2 and Figure 3 , the A flow line 5 includes a Y direction module 51, a first synchronous belt bracket 52 driven to translate by the Y direction module 51, a first synchronous belt line 53 arranged on the inner side of the first synchronous belt bracket 52, and a first blocking mechanism 54 arranged on the discharge direction of the first synchronous belt line 53. The A flow line 5 further includes a jacking mechanism 55 arranged on the inlet side of the first blocking mechanism 54, which vertically penetrates the middle part of the first synchronous belt line 53. The two sides of the first synchronous belt bracket 52 have a first baffle 521 higher than the conveying surface of the first synchronous belt line 53, and the first baffle 521 is provided with a plurality of first stop blocks 522 for preventing the product fixture 200 from rising. The first baffle 521 is provided with a plurality of A line sensors 56 for detecting the arrival position of the product fixture 200.

[0035] The first synchronous belt line 53 is used to convey the product fixture 200 along the X direction, and the first baffle 521 limits the Y direction of both sides of the product fixture 200. The A line sensor 56 is used to determine the position of the product fixture 200, so as to judge when the product fixture 200 is in position and when it is moved out. The blocking mechanism 54 blocks the product fixture 200, so that it first stays in the middle part of the first synchronous belt line 53. In order to prevent the product fixture 200 from moving during processing, the jacking mechanism 55 is used to jack up the product fixture 200 until its upper surface is pressed by the second baffle 522, so as to fix the product fixture 200.

[0036] As shown inFigure 4 As shown, the B-line 6 includes a second synchronous belt support 61, a second synchronous belt line 62 disposed inside the second synchronous belt support 61, and a second blocking mechanism 63 disposed in the discharge direction of the second synchronous belt line 62. The second synchronous belt support 61 has second baffles 611 on both sides that are higher than the conveying surface of the second synchronous belt line 62. The second baffles 611 are provided with multiple second stops 612 and several B-line sensors 64 for detecting the arrival position of the product fixture 200.

[0037] Because streamline B 6 does not require Y-axis translation, its structure is simpler than streamline A 5. The second synchronous belt 62 is used to transport the product fixture 200, while the B-line sensor 64 is used to determine the timing of the product fixture 200's entry and exit. The second baffle 611 and the second stop 612 are used to restrict the movement space of the product fixture 200.

[0038] like Figure 2 As shown, the functional testing station 2b also has a waste discharge station located on the other Y-side of the conveying station, and a waste discharge ramp 7 is provided on the X-side of the waste discharge station. The visual inspection station 2a is the same as the functional testing station 2b except for the visual inspection device, so it will not be described again.

[0039] Because both the visual inspection station 2a and the functional inspection station 2a need to remove defective products, there's no need for defective products to flow into subsequent stations for further processing. Therefore, both need to have an additional waste discharge position, which is the function of the waste discharge ramp 7. When a product is defective, the product fixture 200 is transferred by flow line A 5 to the waste discharge position and then conveyed along the X direction to the waste discharge ramp 7. This way, flow line A 5 can immediately receive the next product fixture 200 upon returning to the conveying position.

[0040] like Figure 1 As shown, the machine 1 is also equipped with an X-direction return line 11, which extends from the outlet side of the UV curing unit 4 to the inlet side of the vision inspection station 2a. The X-direction return line 11 passes under the vision inspection station 2a, the flux spraying station 3a, the welding station 3b, the functional testing station 2b, the dispensing station 3c, and the UV curing unit 4. Above the X-direction return line 11 is a conveying channel, the height of which is greater than the thickness of a single product fixture 200.

[0041] After the PCBA / FPC on the product fixture 200 has completed production, a worker can be stationed at the end of the production line to place the product fixture 200 at the entrance of the X-direction return line 11. The X-direction return line 11 can then return the product fixture 200 to the entrance of the production line, allowing it to be reused. When the X-direction return line 11 is located directly below the workstation, the width occupied by the production line will be smaller, resulting in a more compact structure.

[0042] The working procedure of the full-automatic PCBA / FPC flexible production line 100 is as follows:

[0043] The PCBA is placed on the product fixture 200 and enters the A flow line 5 on the visual inspection work station 2a. The first A flow line 5 moves the product fixture 200 to the lower side of the visual inspection device. After the visual inspection is completed, the qualified product is sent to the first B flow line 6, and the unqualified product is placed on the first waste slope plate 7. Then, the first qualified product is sent to the A flow line 5 of the flux spraying work station 3a. The second A flow line 5 moves the product fixture 200 to the lower side of the flux spraying device to spray flux, and then moves to the second B flow line 6 to wait. Then, the product fixture 200 enters the A flow line 5 of the welding work station 3b. The third A flow line 5 moves the product fixture 200 to the lower side of the welding device to perform HB welding to weld the FPC to the PCBA. Then, the product fixture 200 moves to the third B flow line 6 to wait. Then, the product fixture 200 moves to the A flow line 5 of the function detection work station 2b. The fourth A flow line 5 moves the product fixture 200 to the lower side of the conductive function detection device to perform function detection on the PCBA / FPC. The qualified product is sent to the fourth B flow line 6 to wait, and the unqualified product is sent to the second waste slope plate 7. Then, the product fixture 200 is sent to the A flow line 5 of the dispensing work station 3c. The fifth A flow line 5 moves the product fixture 200 to the lower side of the dispensing device to perform UV dispensing. Then, the PCBA / FPC after dispensing is translated to pass through the UV curing device 4 to perform UV curing. Finally, the product fixture 200 after completing all processes is translated to return to the entrance of the line through the X-direction reflow line 11.

[0044] The above only describes some embodiments of the present application. Those skilled in the art can make some modifications and improvements without departing from the inventive concept, and these modifications and improvements are within the protection scope of the present application.
