Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to an automatic circuit board leveling device. Background Technology

[0002] A circuit board, also known as a printed circuit board, is a fundamental component used to connect and support electronic components. It is typically composed of insulating materials (such as fiberglass or resin) and conductive materials (such as copper). Circuit boards provide electrical connections and signal transmission between electronic components by arranging conductive paths on their surface or inside.

[0003] In existing technologies, the cylinder air pressure is unstable during circuit board leveling, which may cause excessive pressure and damage to the circuit board, thereby increasing the defect rate and reducing production efficiency. At the same time, traditional leveling devices may require manual adjustment when leveling circuit boards of different sizes, which may lead to inaccuracy and increase the scrap rate. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic circuit board leveling device.

[0005] This utility model is achieved by the following technical solution: an automatic circuit board leveling device, comprising a leveling mechanism, a clamping mechanism and a sliding mechanism, wherein the leveling mechanism is located at the top of the clamping mechanism and the sliding mechanism is located at the bottom of the leveling mechanism;

[0006] The leveling mechanism includes a worktable, a support block fixedly connected to the top of the worktable, a slide groove slidably connected to the outer wall of the support block, a fixed plate fixedly connected to the top of the support block, a fixed block fixedly connected to the top of the fixed plate, a cylinder fixedly connected to the outer wall of the fixed block, a connecting column fixedly connected to the output end of the cylinder, the connecting column slidably connected inside the fixed plate, a limit plate fixedly connected to the outer wall of the connecting column, the limit plate slidably connected to the outer wall of the slide groove, an electric heating block fixedly connected to the end of the connecting column away from the cylinder, a limit block contacting the bottom of the limit plate, a first fixed plate fixedly connected to the left side of the limit block, a threaded rod threadedly connected to the first fixed plate, a first fixed block rotatably connected to the outer wall of the threaded rod, the first fixed block fixedly connected to the left side of the fixed plate, a motor fixedly connected to the end of the threaded rod away from the first fixed block, and the motor fixedly connected inside the worktable.

[0007] Through the above technical solution, when the circuit board is at the bottom of the heating block, the cylinder drives the heating block to move through the connecting column. The heating block heats the circuit board while simultaneously applying pressure to flatten it and prevent rebound. At the same time, a limiting plate is fixed to the outer wall of the connecting column. The limiting plate slides on the outer wall of the slide groove and contacts the limiting block at the bottom. The limiting block can prevent the cylinder from applying excessive pressure to the circuit board due to unstable air pressure, which could damage the circuit board. This reduces the defect rate and improves the overall processing quality. In addition, the motor is fixed to the threaded rod, and the threaded rod is threadedly connected to the fixed plate, which allows for precise adjustment of the height of the limiting block at any time. This allows for the leveling of circuit boards of different thicknesses, improving the utilization rate of the equipment.

[0008] As a further improvement to the above solution, the clamping mechanism includes a sliding block, a cylinder is fixedly connected inside the sliding block, and a connecting rod is fixedly connected to the output end of the cylinder.

[0009] As a further improvement to the above solution, the connecting rod is slidably connected inside the sliding block, and a clamping plate is fixedly connected to the end of the connecting rod away from the cylinder one. A circuit board is contacted at the end of the clamping plate away from the connecting rod, and a fixing plate two is contacted at the bottom of the circuit board. The fixing plate two is fixedly connected to the top of the workbench.

[0010] With the above technical solution, when the circuit board is transported to the top of the fixed plate two by the mechanical gripper, the cylinder one pushes the connecting rod to move. The connecting rod is fixed to the clamping plate, thereby fixing the circuit board and preventing it from shifting during leveling. Fixing ensures that the circuit board is in the specified position, thereby improving the leveling accuracy of the circuit board, reducing the time for repeated adjustments, and thus improving work efficiency.

[0011] As a further improvement to the above solution, the sliding mechanism includes a slide groove, which is opened on the top of the worktable. A slider is slidably connected to the outer wall of the slide groove, and the slider is fixedly connected to the bottom of the sliding block. A rack is fixedly connected to the front of the sliding block.

[0012] As a further improvement to the above solution, the rack is meshed with a half gear, and a fixed rod is fixedly connected inside the half gear. The fixed rod is rotatably connected inside the worktable, and a motor is fixedly connected to the bottom end of the fixed rod.

[0013] As a further improvement to the above solution, the motor is fixedly connected inside the workbench, a rack is fixedly connected to the back of the sliding block, a half gear is meshed with the rack, and a fixing rod is fixedly connected inside the half gear.

[0014] As a further improvement to the above solution, the first fixing rod is rotatably connected inside the worktable, and the bottom end of the first fixing rod is fixedly connected to the second motor, which is also fixedly connected inside the worktable.

[0015] Through the above technical solution, motor one drives the half gear to rotate via a fixed rod. The half gear meshes with the rack, while the rack is fixed to the outer wall of the sliding block. A slider is fixed at the bottom of the sliding block, allowing the slider to slide on the outer wall of the slide groove, thus causing the entire sliding block to move. When it moves to a specified distance, the half gear disengages from the rack. Conversely, motor two drives the half gear one to rotate via a fixed rod, and the half gear one meshes with the rack. After leveling is completed, the entire sliding block retracts, causing the sliding block to move back and forth. This keeps the equipment in a back-and-forth operating state, thereby improving processing efficiency.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a cylinder that moves the heating block via a connecting column when the circuit board is at the bottom of the heating block. The heating block heats the circuit board while simultaneously applying pressure to flatten it and prevent rebound. A limiting plate is fixed to the outer wall of the connecting column and slides against the outer wall of the groove, contacting a limiting block at its bottom. This limiting block prevents the cylinder from applying excessive pressure to the circuit board due to unstable air pressure, thus reducing the defect rate and improving overall processing quality. Furthermore, the motor is fixed to a threaded rod, which is threadedly connected to a fixed plate, allowing for precise adjustment of the limiting block's height at any time. This enables the leveling of circuit boards of varying thicknesses, improving equipment utilization.

[0018] When the circuit board is transported to the top of the fixed plate by the mechanical gripper, the cylinder pushes the connecting rod to move. The connecting rod is fixed to the clamping plate, thereby fixing the circuit board and preventing it from shifting during leveling. This fixation ensures that the circuit board is in the specified position, thereby improving the leveling accuracy of the circuit board, reducing the time spent on repeated adjustments, and thus improving work efficiency.

A limit block 110 is provided at the bottom of the limiting plate 108. A fixing plate 111 is fixedly connected to the left side of the limiting block 110. A threaded rod 112 is threadedly connected to the fixing plate 111. A fixing block 113 is rotatably connected to the outer wall of the threaded rod 112. The fixing block 113 is fixedly connected to the left side of the fixing plate 104. A motor 114 is fixedly connected to the end of the threaded rod 112 away from the fixing block 113. The motor 114 is fixedly connected inside the worktable 101.

[0030] The clamping mechanism 2 includes a sliding block 201, a cylinder 202 is fixedly connected inside the sliding block 201, and a connecting rod 203 is fixedly connected to the output end of the cylinder 202.

[0031] The connecting rod 203 is slidably connected inside the sliding block 201. The end of the connecting rod 203 away from the cylinder 202 is fixedly connected to the clamping plate 204. The end of the clamping plate 204 away from the connecting rod 203 is in contact with the circuit board 205. The bottom of the circuit board 205 is in contact with the fixing plate 206. The fixing plate 206 is fixedly connected to the top of the workbench 101.

[0032] The sliding mechanism 3 includes a slide groove 301, which is opened on the top of the worktable 101. A slider 302 is slidably connected to the outer wall of the slide groove 301. The slider 302 is fixedly connected to the bottom of the sliding block 201. A rack 303 is fixedly connected to the front of the sliding block 201.

[0033] The rack 303 is meshed with a half gear 304, and a fixed rod 305 is fixedly connected inside the half gear 304. The fixed rod 305 is rotatably connected inside the worktable 101, and a motor 306 is fixedly connected to the bottom end of the fixed rod 305.

[0034] Motor 306 is fixedly connected inside the worktable 101. A rack 307 is fixedly connected to the back of the sliding block 201. A half gear 308 is meshed with the rack 307. A fixed rod 309 is fixedly connected inside the half gear 308.

[0035] The first fixed rod 309 is rotatably connected inside the worktable 101. The bottom end of the first fixed rod 309 is fixedly connected to the second motor 310, which is also fixedly connected inside the worktable 101.

[0036] The implementation principle of the automatic circuit board leveling device in this application embodiment is as follows: During use, when the circuit board 205 is transported to the top of the fixed plate 206 by the mechanical gripper, the cylinder 202 pushes the connecting rod 203 to move. The connecting rod 203 is fixed to the clamping plate 204, thereby fixing the circuit board 205 and preventing displacement during leveling. This fixation ensures the circuit board 205 is in the specified position, thus improving the leveling accuracy of the circuit board 205, reducing repeated adjustment time, and improving work efficiency. At this time, the motor... Motor 306 drives half gear 304 to rotate via fixed rod 305. Half gear 304 meshes with rack 303, while rack 303 is fixed to the outer wall of sliding block 201. Slider 302 is fixed to the bottom of sliding block 201, allowing slider 302 to slide on the outer wall of sliding groove 301, thus causing sliding block 201 to move as a whole. When it moves to a specified distance, half gear 304 disengages from rack 303. Conversely, motor 310 drives half gear 308 to rotate via fixed rod 309, and half gear 308 meshes with rack 303. When strip 307 engages, after leveling, the sliding block 201 retracts as a whole, causing it to move back and forth. This keeps the equipment in a constant reciprocating motion, improving processing efficiency. When the circuit board 205 is at the bottom of the heating block 109, the cylinder 106 drives the heating block 109 to move via the connecting column 107. The heating block 109 heats the circuit board 205 while simultaneously applying pressure to level it and prevent rebound. At the same time, the limiting plate 108 is fixed to the outer wall of the connecting column 107, and the limiting plate 108 slides. On the outer wall of the slide 103, the bottom of the limiting plate 108 contacts the limiting block 110. The limiting block 110 can prevent the cylinder 106 from causing excessive pressure on the circuit board 205 due to unstable air pressure, which would damage the circuit board 205, thereby reducing the defect rate and improving the overall processing quality. At the same time, the motor 114 is fixed to the threaded rod 112, and the threaded rod 112 is threadedly connected to the fixing plate 111, which can accurately adjust the height of the limiting block 110 at any time. This allows for the leveling of circuit boards 205 of different thicknesses, improving the utilization rate of the equipment.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
