[0040] Example 1

[0041] Please see attached Figure 1-6 A wave soldering carrier disassembly and reflow device comprises a releasing mechanism 1, a separating mechanism 2, a clamping mechanism 4, a PCB board transporting mechanism 3 and a tooling reflow mechanism 5; the output end of the releasing mechanism 1 is connected to the input end of the separating mechanism 2, and the clamping mechanism 4 is located on one side of the separating mechanism 2, for clamping the PCB board and the tooling in the separating mechanism 2 to the PCB board transporting mechanism 3 and the tooling reflow mechanism 5 respectively.

[0042] In this embodiment, the wave soldering carrier 19 includes a tooling and a PCB board embedded in the tooling. The front end of the tooling includes a folded pressure plate 51. When the pressure plate 51 is flipped to the top of the PCB board, the PCB board is tightly fixed in place; when the pressure plate 51 is flipped to the plane where the PCB board is located, the PCB board will not be limited. The PCB board is embedded in the rear end of the tooling, and is fixed at the front and rear ends of the PCB by buckles 21. The buckle 21 includes a fixed end fixed in the tooling and a sliding end that can rotate around the fixed end. When the sliding end slides onto the PCB board, the PCB board is fixed; when the sliding end slides onto the tooling, the buckle 21 will not limit the PCB board. PCB board through holes 28 are provided on the left and right sides of the PCB board to facilitate the clamping of the PCB board during the subsequent separation process.

[0043] The front end and the rear end of this embodiment are relative to the transmission direction of the wave soldering carrier 19. In the wave soldering process, the end that is first output from the release mechanism 1 is the front end, and the end that is later output from the release mechanism 1 is the rear end; similarly, the end that first contacts the track of the wave soldering carrier 19 is the front end, and the end that contacts the track of the wave soldering carrier 19 is the rear end. When the tooling and the PCB board in the wave soldering carrier 19 need to be disassembled and separated, the pressure plate 51 in the wave soldering carrier 19 needs to be flipped to the plane where the PCB board is located, and the sliding end of the buckle 21 is rotated to the top of the tooling, so that the wave soldering carrier 19 is in a released state.

[0044] The release mechanism 1 includes a first fixed rail 6 and a first movable rail 10 arranged in parallel. The first movable rail 10 can move in a direction close to or away from the first fixed rail 6 to adjust the distance between the first fixed rail 6 and the first movable rail 10, so that the device in this embodiment is suitable for wave soldering carriers 19 of different sizes.

[0045] First transmission chains are respectively arranged on opposite sides of the first fixed rail 6 and the first movable rail 10 , and both sides of the wave soldering carrier 19 are respectively located on the two first transmission chains; the two first transmission chains move synchronously, driving the wave soldering carrier to move forward.

[0046] The front end of the first movable rail 10 is provided with a first blocking cylinder 11, which is used to block the wave soldering carrier from moving forward when it moves to the designated position; the rear end and the front end of the first movable rail 10 are respectively provided with a first photodetector 7 and a second photodetector 8; the first photodetector is used to detect whether the wave soldering carrier 19 enters the first transmission chain, and the second photodetector is used to detect whether the wave soldering carrier is blocked by the first blocking cylinder and is in a stationary state. Among them, the first photodetector 7 can be located at the end of the rear end of the first movable rail 10, and the second photodetector 8 can be located at the rear end of the first blocking cylinder 11. Of course, the first blocking cylinder 11, the first photodetector 7 and the second photodetector 8 can also be arranged in the first fixed rail 6.

[0047] The flipping unit includes a flipping cylinder 17 and a flipping swing arm 18. The flipping cylinder 17 is located outside the first fixed rail. The output end of the flipping cylinder is connected to the flipping swing arm 18. The front end of the flipping swing arm 18 includes a fixing ring. When the wave soldering carrier is blocked by the first blocking cylinder 11, the fixing ring is just located in the pressure plate opening 20 above the pressure plate. The flipping cylinder can drive the flipping swing arm 18, the pressure plate opening 20 and the pressure plate to flip together, so that the pressure plate is flipped to the plane where the PCB board is located.

[0048] The button unit includes a fixed frame 12, both ends of which are respectively fixed on the first fixed rail and the first movable rail. A pressure plate cylinder 49 is respectively arranged on the inner side of both ends of the fixed frame 12. The pressure plate cylinder 49 is located above the tooling. When the wave soldering carrier is blocked by the first blocking cylinder 11, the pressure plate cylinder 49 is pressed down to position the tooling to prevent it from moving during the flipping of the pressure plate 51.

[0049] A lever cylinder 13 is arranged above the fixing member; at the same time, the movable plate 14 and the levers 15 located on both sides of the movable plate 14 are slidably connected. The movable plate 14 can reciprocate along the transmission direction perpendicular to the wave soldering carrier 19 driven by the lever cylinder 13. The bottom of the lever 15 is tangent to the buckle 21; as shown in the attached Figure 3 As shown, when the buckle 21 is cam-shaped, the buckle 21 includes two arcs, one large and one small. The large arc is the fixed end, which is fixed to the tooling by screws, and the small arc is the sliding end, which can slide on the tooling and the PCB board. The bottom of the lever 15 is tangent to the buckle, which specifically means that the bottom of the lever 15 is tangent to the outer circle of the large arc, so that during the movement of the lever 15, it is in close contact with the buckle 21, driving it to rotate and open.

[0050] After positioning the wave soldering carrier 19, the present application flips the pressure plate to the plane where the PCB board is located through the flip unit, and the buckle 21 is unscrewed through the lever 15, so that the wave soldering carrier 19 is in a released state, which is convenient for the subsequent separation of the PCB board and the tooling; the distance between the first movable rail and the first fixed rail in the release mechanism 1 in the present application is adjustable, which can be suitable for wave soldering carriers of different sizes, and can realize automatic positioning, flipping and lever 15 of the wave soldering carrier 19, realizing unmanned operation, with a high degree of automation, and significantly improving the release efficiency of the wave soldering carrier 19.

[0051] The separation mechanism 2 includes a second fixed rail 23 and a second movable rail 30 corresponding to the first fixed rail 6 and the first movable rail 10, and the second movable rail 30 can move toward or away from the second fixed rail 23. In this embodiment, the distance between the first fixed rail 6 and the first movable rail 10 is equal to the distance between the second fixed rail 23 and the second movable rail 30, and the objects transmitted by the two are the same. Similarly, a second transmission chain is set on the side opposite to the second fixed rail 23 and the second movable rail 30.

[0052] The front end of the second fixed rail 23 is provided with a second blocking cylinder 26; the rear end and the front end of the second fixed rail 23 are respectively provided with a third photodetector 24 and a fourth photodetector 25; when the third photodetector 24 detects the wave soldering carrier 19, the second blocking cylinder extends; the second transmission chain starts to drive until the wave soldering carrier 19 is blocked by the second blocking cylinder 26, and the second transmission chain stops driving. At this time, the wave soldering carrier 19 is in a released state, that is, the PCB board is no longer restricted by the tooling, and the PCB board can be easily taken out through the PCB board through holes 28 on both sides of the PCB board; at the same time, the gap of the pressure plate and the end of the tooling constitute the tooling clamping position 31. The clamping mechanism 4 can only start the clamping action when the fourth photodetector 25 detects that the wave soldering carrier is stationary.

[0053] The clamping mechanism 4 includes a robot 33, the front end of the robot 33 is provided with a clamping swing arm that can swing freely in three-dimensional space, the front end of the clamping swing arm is provided with a clamping unit, the clamping unit includes a PCB clamping subunit and a tooling clamping subunit, the PCB clamping subunit includes a first clamping cylinder 36 and first clamping blocks 37 on both sides and parallel to the first clamping cylinder 36; wherein the first lifting cylinder 35, the first lifting cylinder 35 is connected to the first clamping cylinder 36, used to drive the first clamping cylinder 36 to lift, the first clamping cylinder 36 is connected to the first clamping block 37, used to drive the two first clamping blocks 37 to tighten and loosen. The first lifting cylinder 35 and the second lifting cylinder 38 are fixed together at the front end of the clamping swing arm through the fixture mounting plate 34.

[0054] The tool clamping subunit includes a second lifting cylinder 38, a second clamping cylinder 39, and second clamping blocks 40 on both sides of and parallel to the second clamping cylinder 39; wherein the second lifting cylinder 38 is connected to the second clamping cylinder 39 to drive the second clamping cylinder 39 to lift and lower, and the second clamping cylinder 39 is connected to the second clamping block 40 to drive the tightening and loosening of the two second clamping blocks 40. The tool clamping subunit directly clamps the tool and transmits it to the tool return mechanism 5, and a transmission chain is set on the upper surface of the tool return mechanism 5 to output the tool.

[0055] The PCB board transport mechanism 3 includes a third fixed rail 42 and a third movable rail 45. Similarly, the third movable rail 45 can move in a direction close to or away from the second fixed rail 23. In this embodiment, the distance between the third fixed rail 42 and the third movable rail 45 is smaller than the distance between the second fixed rail 23 and the second movable rail 30. The third fixed rail 42 and the third movable rail 45 are used to transport the PCB board 44, and the width of the PCB board 44 is smaller than the width of the wave soldering carrier 19. Similarly, a third transport chain is arranged on the side opposite to the third fixed rail 42 and the third movable rail 45.

[0056] A fifth photodetector 43 and a sixth photodetector 48 are respectively disposed at the rear end and the front end of the third fixed rail 42; the fifth photodetector 43 detects whether a PCB board is placed on the third transmission chain, and the sixth photodetector 48 is used to detect whether the PCB board is output. A PCB board clamping position 46 is also disposed on both sides of the third movable rail 45 and the third fixed rail 42. When the PCB clamping subunit places the PCB board on the third transmission chain, the first clamping block 37 after being released is exactly located at the PCB board clamping position 46, and then moves out of the PCB board clamping position 46 under the drive of the clamping swing arm.

[0067] S022: When the third photoelectric detector 24 detects that the wave soldering carrier enters the second transmission chain, the second blocking cylinder 26 extends; at the same time, the second transmission chain drives the wave soldering carrier to move until it is blocked by the second blocking cylinder 26;

[0068] S03: When the fourth photoelectric detector 25 detects that the wave soldering carrier is stationary, the clamping mechanism 4 first clamps the PCB board and transfers it to the PCB board transport mechanism for output; then clamps the tooling and transfers it to the tooling reflow mechanism 5 for output. Specifically including:

[0069] S031: The fourth photoelectric detector 25 located at the rear end of the second blocking cylinder 26 detects that the wave soldering carrier is stationary; the clamping swing arm in the robot 33 drives the PCB board clamping subunit to move above the PCB board, the first lifting cylinder 35 extends downward, and the two first clamping blocks 37 fall into the two PCB board through holes 28 respectively, the first clamping cylinder 36 drives the first clamping blocks 37 to tighten, and the first lifting cylinder 35 drives the PCB board and the first clamping blocks 37 to shrink upward, so that the PCB board is separated from the wave soldering carrier 19;

At the same time, the loosened first clamping block 37 is located in the PCB board clamping position 46, and the first lifting cylinder drives the first clamping block 37 to retract upward. After the fifth photoelectric detector 43 detects the PCB board, the third transmission chain starts to move, and the PCB board clamping subunit can place the next PCB board 44 to the PCB board transport mechanism 3 until the sixth photoelectric detector 48 detects the PCB board.

[0071] S033: The clamping swing arm in the robot 33 drives the tooling clamping unit to move above the tooling, the second lifting cylinder 38 extends downward, the two second clamping blocks 40 respectively fall to the two tooling clamping positions 31, the second clamping cylinder 39 drives the second clamping blocks 40 to tighten, the second lifting cylinder 38 drives the tooling and the second clamping blocks 40 to retract upward, and places the tooling in the tooling reflux mechanism 5 for transmission.

[0072] The PCB board and the tooling in the wave soldering carrier in the released state are in an independent state. In this application, the robot first drives the PCB board clamping subunit to clamp the PCB board and place it on the PCB board transportation mechanism output, and then drives the tooling clamping subunit to clamp the tooling and place it on the tooling reflow mechanism output, thereby realizing the automatic separation of the PCB board and the tooling in the wave soldering carrier in the released state, and further improving the separation efficiency.
