Description

Technical Field

[0001] This utility model relates to the field of PCB production equipment technology, specifically to a PCB carrier for reflow soldering. Background Technology

[0002] PCB, or Printed Circuit Board, is an electronic component printed and spatially arranged for mounting electronic components. Surface Mount Technology (SMT) is a circuit assembly technology that mounts leadless or short-lead surface-mount components onto the surface of a PCB and assembles them using methods such as reflow soldering or dip soldering. Typically, after the bare PCB has undergone SMT component loading, it passes through a reflow oven where the solder paste on the PCB melts at high temperatures and then cools, ultimately stabilizing the components. To prevent electronic components from deforming or falling off during the reflow process, carriers are used to hold the components in place.

[0003] Currently, the width of existing PCB carriers for reflow soldering is fixed during use. When it is necessary to change to a PCB with a different width, the carrier tool needs to be changed to a carrier tool of the corresponding size, or a larger carrier tool needs to be used, and other auxiliary fixing tools are used for fixing. This operation is relatively troublesome and greatly reduces work efficiency. Therefore, this utility model provides a PCB carrier for reflow soldering. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-6 As shown, this embodiment proposes a PCB carrier for reflow soldering, including a carrier base plate 1, a groove 2 is provided on the carrier base plate 1, clamping plates 3 are symmetrically arranged in the groove 2, the clamping plates 3 are hollow inside, an adjustment component 100 is provided at the bottom of the carrier base plate 1, and a fixing component 200 is provided on the clamping plates 3.

[0029] The adjustment assembly 100 includes a dual-axis motor 101 fixedly installed on the bottom of the vehicle base plate 1. The input end of the dual-axis motor 101 is connected to a power source via an external cable. Threaded rods 102 are fixedly installed on the output ends of both ends of the dual-axis motor 101. Support plates 103 are fixedly installed on both symmetrical sides of the bottom of the vehicle base plate 1. T-shaped slide bars 104 are fixedly installed on both symmetrical sides of the bottom of the vehicle base plate 1. T-shaped slide rails 105 are slidably connected to the outer surfaces of the two T-shaped slide bars 104. The T-shaped slide bars 104 and T-shaped slide rails 105 are matched. The top of both support plates 103 has slots to facilitate the movement of the T-shaped slide rails 105. Connecting plates 106 are fixedly installed on one side of the bottom of both T-shaped slide rails 105. Two threaded rods 102 are threaded through one end away from the dual-axis motor 101 and pass through one side of the corresponding connecting plate 106 and are rotatably connected to the side wall of the support plate 103. One end of the two T-shaped slide rails 105 is fixedly installed with a connecting vertical rod 107. One side of the top of the two connecting vertical rods 107 is fixedly installed with a sliding rod 108. One end of the two sliding rods 108 is movably passed through the groove 2 and fixedly installed at one end of the corresponding clamping plate 3. Sliding blocks 109 are fixedly installed on both sides of the two clamping plates 3. Sliding slots 110 are opened on both sides of the groove 2. The sliding blocks 109 match the sliding slots 110. Clamping components 300 are installed on both clamping plates 3.

[0030] The clamping assembly 300 includes a drive motor 301 fixedly installed on one side of the clamping plate 3. The input end of the drive motor 301 is connected to a power supply via an external cable. A bidirectional screw 302 is fixedly installed on the output end of the drive motor 301. The end of the bidirectional screw 302 away from the drive motor 301 is rotatably connected to the inner wall of the clamping plate 3. Moving blocks 303 are threadedly connected to the outer surfaces of both ends of the bidirectional screw 302. A moving groove 304 is opened on one side of the clamping plate 3. The moving block 303 matches the inner wall of the clamping plate 3. A bearing plate 305 is fixedly installed on one side of the moving block 303. One end of the bearing plate 305 extends movably through to one side of the moving groove 304. A baffle 306 is fixedly installed on one side of the bearing plate 305. The bottom of the clamping plate 3 and the bottom of the baffle 306 are in contact with the bottom wall of the groove 2.

[0031] The adjustable component 100 can effectively adjust the clamping according to different specifications of the PCB board. When it is necessary to adjust the clamping according to different specifications of the PCB board, the dual-axis motor 101 is started to drive the threaded rod 102 to rotate. The threaded rod 102 drives the T-shaped slide rail 105 on one side of the two connecting plates 106 to move along the T-shaped slide bar 104. While the T-shaped slide rail 105 is moving, it drives the sliding rod 108 on one side of the connecting vertical rod 107 to move, thereby driving the two clamping plates 3 to move relative to each other. While the clamping plates 3 are moving, the sliding block 109 and the sliding slot 110 cooperate to make the clamping plates 3 move horizontally and stably. Then, the drive motor 301 is started to drive the bidirectional screw 302 to rotate. The bidirectional screw 302 drives the two moving blocks 303 to move relative to each other, thereby driving the baffle 306 on one side of the bearing plate 305 to move relative to each other, thereby adjusting the clamping according to different specifications of the PCB board.

[0032] Example 2

[0033] like Figures 1-6As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a fixing component 200 including a support base 201 fixedly installed on one side of the top of the bearing plate 305. A clamping fixing plate 202 is rotatably connected to the support base 201. An mounting plate 203 is fixedly installed on one side of the top of the clamping fixing plate 202. An electric push rod 204 is rotatably connected to one side of the mounting plate 203. The input end of the electric push rod 204 is connected to a power source via an external cable. The output end of the electric push rod 204 is rotatably connected to a rocker arm 205. A movable groove 206 is provided on the clamping fixing plate 202. A cam 207 is rotatably connected, and the bottom end of a rocker arm 205 is fixedly installed on the top of the cam 207. The cam 207 is in contact with the top of the support plate 305. The fixed component 200 can effectively fix the clamped PCB board. When it is necessary to fix the clamped PCB board, the electric push rod 204 is activated to move the rocker arm 205. The rocker arm 205 drives the cam 207 to rotate in the movable groove 206. The rotation of the cam 207 drives the clamping and fixing plate 202 to rotate, thereby fixing one end of the clamping and fixing plate 202 to fix the clamped PCB board.

[0034] During operation, the PCB board is first placed into the groove 2. Then, the dual-axis motor 101 is started to drive the threaded rod 102 to rotate. The threaded rod 102 drives the T-shaped slide rail 105 on one side of the two connecting plates 106 to move along the T-shaped slide bar 104. While the T-shaped slide rail 105 is moving, it also drives the sliding rod 108 on one side of the connecting vertical rod 107 to move, thereby causing the two clamping plates 3 to move relative to each other. While the clamping plates 3 are moving, the cooperation of the sliding block 109 and the sliding slot 110 makes the clamping plates 3 move horizontally and stably to clamp the width of the PCB board. Then, the drive motor 301 is started to drive the bidirectional screw 302 to rotate. The bidirectional screw 302 drives the two moving blocks 303 to move relative to each other. The two moving blocks 303 drive the baffle 306 on one side of the bearing plate 305 to move relative to each other, thereby clamping the length of the PCB board. Then, the electric push rod 204 is started to drive the rocker arm 205 to move. The rocker arm 205 drives the cam 207 to rotate in the movable groove 206. The rotation of the cam 207 drives the clamping fixing plate 202 to rotate, thereby driving one end of the clamping fixing plate 202 to fix the clamped PCB board.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
