[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: a negative pressure adsorption component welding tray, including a tray body 1, a suction cup 2, an air pipe 3, an air pump 4, an air hole 5, a support seat 6, a turntable 7, a block 8, a knob 9, a cylinder 10, a push rod 11, a spring 12, a base 13, a support column 14, a support column 2 15, and a fixing block 16.

[0031] This device has the effect of separating the circuit board after welding is completed, specifically:

[0032] A support seat 6 is arranged below the tray body 1. The support seat 6 is an open structure. An air pump 4 is fixedly installed on the surface of the support seat 6. Air pipes 3 are connected to both ends of the air pump 4. One end of the air pipe 3 passes through the lower surface of the support seat 6, and the other end of the air pipe 3 is rotatably connected to a suction cup 2. The suction cup 2 is an arched structure, and the surface of the suction cup 2 contacts the lower surface of the tray body 1. A plurality of air holes 5 are arranged in an annular manner on the surface of the tray body 1, and the arrangement area of ​​the air holes 5 is smaller than the diameter range of the suction cup 2. An ejection structure is arranged on the surface of the tray body 1. The ejection structure separates the soldered circuit board from the tray body 1 by the movement of the push rod 11 for easy removal. The ejection structure includes a cylinder 10. The cylinder 10 is a hollow structure. A push rod 11 is slidably connected to the upper surface of the cylinder 10. A spring 12 is arranged at one end of the push rod 11, and the other end of the spring 12 is fixed inside the push rod 11. The other end of the push rod 11 passes through the surface of the tray body 1. Two groups of cylinders 10 and push rods 11 are symmetrically arranged.

[0033] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the circuit board to be soldered is placed on the upper surface of the tray body 1. At this time, the surface of the circuit board covers the push rod 11. The air pump 4 is started, and the air pump 4 draws out the air in the suction cup 2 through the air pipe 3. Since the suction cup 2 is in contact with the lower surface of the tray body 1, the air hole 5 on the surface of the tray body 1 is in a state of communication with the suction cup 2. The circuit board pushes the push rod 11 downward under negative pressure. The push rod 11 slides downward on the surface of the cylinder 10 and compresses the spring 12. The circuit board compresses the push rod 11 downward until it is in close contact with the upper surface of the tray body 1. At this time, the air in the suction cup 2 is continuously pumped out by the air pump 4. The air pressure in the suction cup 2 is reduced, so that the suction cup is tightly connected with the tray body 1, and the circuit board is adsorbed on the surface of the tray body 1. At this time, the welding process of components can be carried out on the surface of the circuit board. When the welding is completed, the air pump 4 is started to blow air into the suction cup 2, so that the atmospheric pressure in the suction cup 2 is restored to balance with the outside, the suction cup 2 loses the adsorption force on the circuit board, and the push rod 11 loses the pressure of the circuit board at the same time. Under the action of the spring 12, the push rod 11 rebounds inside the cylinder 10, and the push rod 11 moves upward to push the circuit board, so that the circuit board is separated from the surface of the tray body 1, so as to facilitate the removal of the welded circuit board.

[0034] The device has the effect of adjusting the height and rotating the circuit board, specifically:

[0035] The surface of the support seat 6 is provided with a rotating structure, and the rotating structure can drive the tray body 1 to rotate by using a turntable 7, so as to facilitate the welding of components in different directions on the surface of the tray body 1. The rotating structure includes a turntable 7, which is a circular ring structure, and the turntable 7 is rotatably connected to the bottom surface of the support seat 6, and the upper surface of the turntable 7 is connected to the bottom surface of the cylinder 10. The outer surface of the turntable 7 is a ratchet structure, and a clamping block 8 is provided on one side of the turntable 7. The clamping block 8 is rotatably connected to the bottom surface of the support seat 6, and the clamping block 8 is a ratchet structure. The bottom surface of the support seat 6 is rotatably provided with a knob 9, and the surface of the knob 9 is driven by the rotating shaft of the support seat 6. The surface of the knob 9 passes through the front surface of the support seat 6, and the lower surface of the support seat 6 is provided with an adjustment structure, which uses a support column 14 and a support column 2 15 to adjust the height of the device, so as to facilitate use by different users. The adjustment structure includes a base 13, and the upper surface of the base 13 is provided with a support column 14, and the outer surface of the support column 14 is sleeved with a support column 2 15, and the other end of the support column 2 15 is connected to the lower surface of the support seat 6, and the outer surface of the support column 14 is provided with a thread, and the outer surface of the support column 14 is threadedly connected with a fixing block 16, and the four corners of the base 13 are respectively provided with support columns 14;

[0036] like Figure 1 , Figure 2 and Figure 6As shown, when the height of the device needs to be adjusted, the handheld support seat 6 is lifted up, and the upward movement of the support seat 6 drives the support column 2 15 on the lower surface to slide upward on the surface of the support column 1 14, so that the height of the device is increased. When it is adjusted to a suitable height, the fixed block 16 on the surface of the support column 14 is rotated, and the fixed block 16 rotates on the surface of the support column 14 and supports the support column 2 15. During the operation of the device, the knob 9 on the outer surface of the support seat 6 is turned, and the rotation of the knob 9 drives the turntable 7 to rotate, and the rotation of the turntable 7 drives the upper tray body 1 to rotate, thereby driving the circuit board to rotate, which is convenient for the user to weld the circuit board in different directions. Since the suction cup 2 and the air pipe 3 are rotatably connected, the suction cup 2 rotates synchronously with the rotation of the tray body 1 during the rotation of the tray body 1, and no interference occurs. The outer surface of the turntable 7 is a ratchet structure, and the bottom surface of the support seat 6 is provided with a block 8 of a ratchet structure, so that the turntable 7 can only rotate in one direction, preventing the tray body 1 from rotating in the opposite direction due to the friction of the user's hand during the welding process.

[0037] Working principle: When using the negative pressure adsorption component welding tray, the air pump 4 is used to evacuate the suction cup 2 so that the circuit board is firmly adsorbed on the surface of the tray body 1, and a push rod 11 is set through the surface of the tray body 1. After welding is completed, the push rod 11 moves upward under the action of the spring 12 to push the circuit board upward, so as to facilitate the separation of the circuit board from the tray body 1 after welding. The knob 9 on the surface of the device can drive the turntable 7 to rotate, and the rotation of the turntable 7 drives the tray body 1 to rotate, thereby driving the circuit board to rotate, so as to facilitate welding of the circuit board in different directions. The device is supported by support column 1 14 and support column 2 15, and support column 2 15 can slide on the surface of support column 1 14, so that the height of the device can be adjusted to adapt to different users, thereby increasing the overall practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
