Description

Technical Field

[0001] This utility model relates to the field of carrier technology, and in particular to a reflow carrier for SMT processes. Background Technology

[0002] SMT is an abbreviation for Surface Mount Technology, which is an electronic assembly technology that uses professional automated assembly equipment such as solder paste printers, pick-and-place machines, and reflow soldering machines to directly attach and solder surface mount components onto the surface of a circuit board. It is one of the technologies commonly used in the production of computer components. SMT reflow trays or reflow carriers are trays or carriers used to hold PCBs and then take them to the reflow oven.

[0003] However, it still has the following drawbacks in practical use:

[0004] After the reflow oven is used, the circuit boards need to be removed from the carrier for subsequent use. However, this is usually done manually, which is inefficient and increases the workload. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to a reflow carrier for SMT processes, comprising:

Third pulleys are symmetrically disposed on the inner walls of the front and rear ends of the second connecting belt.

[0014] Furthermore, a protective frame is provided at the lower end of the vehicle body, and a lifting mechanism is provided inside the protective frame.

[0015] Specifically, the lifting mechanism is protected by a protective frame.

[0016] Furthermore, the main body of the vehicle is provided with four placement slots at equal intervals, and the end of the placement slot away from the rotating lead screw has a corresponding slot;

[0017] Specifically, the circuit board is placed in the slot.

[0018] Furthermore, a rotating seat is provided on the outer circumference of the rotating screw, and four first limiting frames are equidistantly arranged on the outer circumference of the rotating screw, with a buffer pad provided on the lower side of the end of the first limiting frame;

[0019] Specifically, the rotating seat drives the rotating screw to rotate, and the rotating screw drives the first limit frame to move up and down, and the buffer pad contacts the circuit board to protect the circuit board.

[0020] Furthermore, the main body of the vehicle is symmetrically provided with rotating shafts on the left and right sides. The rotating shafts are connected to the active gears. The outer circumferential wall of the active gears meshes with the limiting teeth. The outer circumferential wall of the rotating shafts is symmetrically provided with second limiting frames at the front and rear.

[0021] Specifically, the rotation angle of the second limit frame is adjusted by manually rotating the drive gear and limiting the rotation angle of the drive gear by the limit gear.

[0022] Furthermore, the second limiting frame is configured to correspond to the corresponding slot, and the first limiting frame is configured to correspond to the placement slot;

[0023] Specifically, when the second limit frame rotates, the rotation angle of the second limit frame is increased through the corresponding slot.

[0025] Specifically, rotating the lead screw drives the connecting shaft to rotate, and when the third pulley rotates, it drives the lifting lead screw to rotate, which in turn drives the lifting frame to move up and down.

[0026] Beneficial effects

[0027] Compared with existing technologies, the advantages of this utility model are:

[0028] I.

[0029] II. In this utility model, after the circuit board is placed in the placement slot, the rotating seat is manually rotated to drive the rotating screw to rotate. The rotating screw drives the first limiting frame to move up and down. The buffer pad contacts the circuit board to protect it. By manually rotating the active tooth, the rotation angle of the active tooth is limited by the limiting tooth, thereby adjusting the rotation of the second limiting frame. When the second limiting frame rotates, the rotation angle of the second limiting frame is increased by the corresponding slot, which can limit the circuit board and prevent the circuit board from shifting.

[0044] Vehicle mechanism 1 includes vehicle body 101;

[0045] The first limiting mechanism 2 includes a rotating lead screw 201 disposed at the middle of the upper end of the carrier body 101;

[0046] The second limiting mechanism 3 includes active teeth 301 symmetrically arranged on the outer wall of the front end of the vehicle body 101.

[0047] The lifting mechanism 4 includes a connecting shaft 401 disposed on the lower outer wall of the carrier body 101. A first pulley 402 is connected to the lower end of the connecting shaft 401. A first connecting belt 403 is disposed on the outer circumference of the first pulley 402. A second pulley 404 is symmetrically disposed on the left and right sides of the inner wall of the first connecting belt 403. A second connecting belt 405 is disposed on the outer circumference of the rear end of the second pulley 404. A third pulley 406 is symmetrically disposed on the front and rear inner walls of the second connecting belt 405.

[0048] The upper end of the connecting shaft 401 is connected to the rotating lead screw 201, and the upper end of the third pulley 406 is connected to the lifting lead screw 407, which passes through the placement groove 103. The outer circumference of the lifting lead screw 407 is provided with a lifting frame 408.

[0049] Lift the circuit board and follow these steps;

[0050] When the rotary seat 202 is manually rotated, the rotary seat 202 drives the rotating screw 201 to rotate, the rotating screw 201 drives the connecting shaft 401 to rotate, the connecting shaft 401 drives the first pulley 402 to rotate, the first pulley 402 drives the first connecting belt 403 to rotate, the first connecting belt 403 drives the second pulley 404 to rotate, the second pulley 404 drives the second connecting belt 405 to rotate, the second connecting belt 405 drives the third pulley 406 to rotate, and when the third pulley 406 rotates, it drives the lifting screw 407 to rotate, and the lifting screw 407 drives the lifting frame 408 to move up and down.

[0051] This step makes it easier to lift the circuit boards inside the carrier, reducing the workload.

[0052] Example 2

[0053] Please see Figure 1-4 As shown, this embodiment, based on embodiment 1 above, further includes:

[0054] A protective frame 102 is provided at the lower end of the vehicle body 101, and a lifting mechanism 4 is provided in the inner cavity of the protective frame 102;

[0055] The main body 101 of the vehicle is provided with four placement slots 103 at equal intervals, and the end of the placement slot 103 away from the rotating screw 201 has a corresponding slot 104.

[0056] A rotating seat 202 is provided on the outer circumference of the rotating screw 201, and four first limit frames 203 are equidistantly arranged on the outer circumference of the rotating screw 201. A buffer pad 204 is provided on the lower side of the end of the first limit frame 203.

[0059] The circuit board is positioned to limit its movement; the following steps are described.

[0060] After placing the circuit board in the placement slot 103, manually rotate the rotating base 202 to drive the rotating screw 201 to rotate. The rotating screw 201 drives the first limiting frame 203 to move up and down. The buffer pad 204 contacts the circuit board to protect it. By manually rotating the active tooth 301, the rotation angle of the active tooth 301 is limited by the limiting tooth 302, thereby adjusting the rotation of the second limiting frame 304. When the second limiting frame 304 rotates, the rotation angle of the second limiting frame 304 is increased through the corresponding slot 104.
