Description

Technical Field

[0001] This utility model relates to the field of circuit board surface mount technology, specifically to a high-efficiency circuit board surface mount device. Background Technology

[0002] High-efficiency surface mount technology (SMT) equipment, also known as automated surface mount technology equipment, is a mechanical device used to quickly and accurately mount electronic components onto circuit boards. This device is widely used in modern electronics manufacturing to improve production efficiency, ensure assembly accuracy, and reduce human error.

[0003] In the existing technology, the process of mounting circuit boards is inefficient and the overall operation is quite cumbersome.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN218388149U) discloses a patch mounting device for circuit board processing, including a frame, a mounting bracket welded to the upper outer surface of the frame, a buffer rubber seat slidably connected to the upper inner surface of the frame, a circuit board body placed on the upper outer surface of the buffer rubber seat, a telescopic clamping plate provided on the upper inner surface of the buffer rubber seat, a threaded rotating rod rotatably connected to the front inner surface of the mounting bracket, and a movable plate threadedly connected to the outer wall of the threaded rotating rod. This patch mounting device for circuit board processing clamps and holds the circuit board using the telescopic clamping plate. At this time, a first spring buffers the pressure on the circuit board from the buffer rubber seat, preventing damage to the circuit board due to the pressure of patch mounting. The patch mounting device moves back and forth to perform patch mounting work on multiple circuit boards. Simultaneously, a third spring allows the rubber protrusion to elastically deform and adaptively compress the telescopic clamping plate, thereby ensuring the clamping effect of the telescopic clamping plate on the circuit board and improving the patch mounting accuracy.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, during the process of moving the circuit board to a specific position before surface mounting, instability can easily cause the circuit board to shift. The limiting force on the circuit board is too small, which is not conducive to stable and efficient surface mounting. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency board mounting device to solve the problem mentioned in the background art that, during the process of moving the board to a specific position before mounting, instability can easily cause the board to shift, resulting in insufficient restraint force on the board and hindering stable and efficient board mounting.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency board mounting device, comprising a bracket and a board body disposed inside the bracket, wherein a mounting end is installed at the upper end of the bracket; a movable support is disposed on the inner side of the bracket, and the lower end of the board body is placed on the upper end of the movable support, and an auxiliary positioning mechanism is disposed on the inner side of the movable support; a fixed base is installed at the upper end of the bracket, and an electric push rod is installed through the middle of the fixed base, and a partition is fixedly installed at the lower end of the electric push rod; a self-removal cooling mechanism is disposed at the upper end of the fixed base, and a collection box is disposed on the right side of the bracket.

[0008] Furthermore, the auxiliary positioning mechanism is provided with a reciprocating threaded rod, and the left and right ends of the reciprocating threaded rod are rotatably installed inside the bracket. A motor is provided at the left end of the reciprocating threaded rod, and the lower end of the motor is installed on the outside of the bracket.

[0009] Furthermore, the reciprocating threaded rod is threadedly installed at the rear end of the movable support, and a limit rod is installed through the front end of the movable support, with the left and right ends of the limit rod fixedly installed on the inner wall of the bracket.

[0010] Furthermore, a damper is installed through the inner side of the movable support, and a positioning plate is installed at the lower end of the damper. The positioning plate is tilted to the left, and a pressure spring is provided between the positioning plate and the movable support.

[0011] Furthermore, the self-removing cooling mechanism is provided with a storage compartment, and the lower end of the storage compartment is fixedly installed on the upper end of the fixed base. An auxiliary pressure plate is installed through the upper end of the partition, and the upper end of the auxiliary pressure plate is attached to the inner wall of the storage compartment.

[0012] Furthermore, the storage compartment is equipped with an elastic airbag, and the lower end of the elastic airbag is installed on the upper end of the fixed base, and the elastic airbag and the auxiliary pressure plate form a pressing structure.

[0013] Furthermore, a jet nozzle is fixedly installed on the right side of the fixed base, with the lower end of the jet nozzle aligned with the inner side of the bracket. The jet nozzle is connected to the elastic airbag through a duct. A one-way air inlet is installed through the left side of the elastic airbag, and a one-way valve is provided inside the one-way air inlet.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When mounting the circuit board, place the circuit board body on the movable support and embed the circuit board body along the left inclined part of the positioning plate. After the circuit board body is embedded, the positioning plate can position the circuit board through the setting of pressure spring and damper, which makes it convenient for the user to install and place the circuit board body.

[0016] Furthermore, by starting the motor on the left side of the reciprocating threaded rod, the motor drives the reciprocating threaded rod to rotate. The surface of the reciprocating threaded rod is threadedly connected to the movable support, and the movable mounting end is used to mount the circuit board body by lowering the mounting end. This allows for convenient mounting with high mounting efficiency.

[0017] 2. When the circuit board body moves to the rightmost end of the bracket, as the circuit board body passes the partition, the electric push rod inside the fixing seat is activated. The activation of the electric push rod causes the partition to descend, so that the partition is located to the left of the circuit board body. This allows the circuit board body to fall into the collection box, making it easy to remove the circuit board body. This makes it easy to remove the circuit board body after it has been mounted.

[0018] Furthermore, as the partition descends, it causes the auxiliary pressure plate to slide along the inside of the storage compartment, squeezing the elastic airbag. The squeezed elastic airbag delivers the internal air to the jet nozzle through the air duct. At this time, the jet nozzle blows air onto the surface of the circuit board body. After the jet nozzle blows air onto the surface of the circuit board body, it can promote air circulation on the surface of the circuit board body, so that the circuit board body can cool down faster after being mounted.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figures 1-4 The technical solution shown is a high-efficiency board mounting device. To solve the problem of inconvenient positioning, it discloses: a bracket 1 and a board body 2 disposed inside the bracket 1, with a mounting end 3 installed at the upper end of the bracket 1; a movable support 5 is disposed inside the bracket 1, with the lower end of the board body 2 placed on the upper end of the movable support 5, and an auxiliary positioning mechanism is disposed inside the movable support 5. The auxiliary positioning mechanism is provided with a reciprocating threaded rod 4, and the left and right ends of the reciprocating threaded rod 4 are rotatably mounted inside the bracket 1. A motor is disposed at the left end of the reciprocating threaded rod 4, and the lower end of the motor is installed on the outside of the bracket 1. The reciprocating threaded rod 4 is threadedly mounted to the rear end of the movable support 5, and a limit rod 6 is installed through the front end of the movable support 5. The left and right ends of the limit rod 6 are fixedly installed on the inner wall of the bracket 1. A damper 7 is installed through the inner side of the movable support 5, and a positioning plate 9 is installed at the lower end of the damper 7. The positioning plate 9 is tilted on the left side, and a pressure spring 8 is disposed between the positioning plate 9 and the movable support 5.

[0028] When mounting the circuit board, place the circuit board body 2 on the movable support 5, such as... Figure 4 As shown, the circuit board body 2 is embedded along the left inclined side of the positioning plate 9. After the circuit board body 2 is embedded, the positioning plate 9 can position the circuit board through the setting of the pressure spring 8 and the damper 7, which facilitates the user to install and place the circuit board body 2. When surface mounting is required, such as... Figure 1 and Figure 3 As shown, by starting the motor on the left side of the reciprocating threaded rod 4, the motor drives the reciprocating threaded rod 4 to rotate. With the threaded connection between the surface of the reciprocating threaded rod 4 and the movable support 5, the rotation of the reciprocating threaded rod 4 can drive the movable support 5 to move under the limit of the limit rod 6. At the same time, in conjunction with the movable mounting end 3, the mounting end 3 descends to mount the circuit board body 2, thereby facilitating the mounting process and achieving high mounting efficiency.

[0029] Example 2: Figures 1-6As shown, the technical solution disclosed in this embodiment, based on the first embodiment, addresses the problem of inconvenient circuit board removal by providing the following: a fixed base 10 is mounted on the upper end of the bracket 1, and an electric push rod 11 is installed through the middle of the fixed base 10. A partition 12 is fixedly mounted on the lower end of the electric push rod 11. A self-removing cooling mechanism is provided on the upper end of the fixed base 10. A collection box is provided on the right side of the bracket 1. The self-removing cooling mechanism includes a storage compartment 13, and the lower end of the storage compartment 13 is fixedly mounted on the upper end of the fixed base 10. An auxiliary pressure device is installed through the upper end of the partition 12. Plate 14, and the upper end of the auxiliary pressure plate 14 is attached to the inner wall of the storage compartment 13. The storage compartment 13 is provided with an elastic airbag 15, and the lower end of the elastic airbag 15 is installed on the upper end of the fixed base 10. The elastic airbag 15 and the auxiliary pressure plate 14 form a pressing structure. The right side of the fixed base 10 is fixedly installed with a jet nozzle 16, and the lower end of the jet nozzle 16 is aligned with the inner side of the bracket 1. The jet nozzle 16 and the elastic airbag 15 are connected by an air guide tube. The left side of the elastic airbag 15 is provided with a one-way air inlet 17, and a one-way valve is provided inside the one-way air inlet 17.

[0030] When the circuit board body 2 moves to the rightmost end of the bracket 1, as the circuit board body 2 passes the partition 12, as... Figure 5 As shown, by activating the electric push rod 11 inside the fixed base 10, the activation of the electric push rod 11 causes the partition 12 to descend, so that the partition 12 is located on the left side of the electric plate body. When the reciprocating threaded rod 4 continues to drive the movable support 5 to move, the movable support 5 moves to the left to reset. At this time, the partition 12 blocks the circuit board body 2, and the circuit board body 2 is blocked from the positioning plate 9, so that the circuit board body 2 can fall into the collection box and be easily removed. This allows the circuit board body 2 to be easily removed after it has been mounted. Figure 6 As shown, as the partition 12 descends, the partition 12 drives the auxiliary pressure plate 14 to slide along the inside of the storage compartment 13 and compress the elastic airbag 15. The elastic airbag 15 is compressed and the air inside is delivered to the jet nozzle 16 through the air guide tube. At this time, the jet nozzle 16 blows air onto the surface of the circuit board body 2. Conversely, when the elastic airbag 15 stops being compressed by the auxiliary pressure plate 14, air is introduced through the one-way valve inside the one-way air inlet 17, so that the elastic airbag 15 can be re-inflated. It can be used repeatedly. After the jet nozzle 16 blows air onto the surface of the circuit board body 2, it can promote the air circulation on the surface of the circuit board body 2, so that the circuit board body 2 can cool down faster after being mounted.
