Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and more specifically, to an auxiliary welding device for remote control circuit boards. Background Technology

[0002] Circuit boards are important components in electronic devices. By connecting circuit boards, the circuits between various components can be connected, enabling the device to work properly. Circuit boards also have many advantages such as small size and light weight. In the production process of remote controls, the soldering of circuit boards is a key step.

[0003] Because the height of the battery electrode is greater than the thickness of the circuit board, the operator needs to move the remote control circuit board to the edge of the soldering table during the soldering process, hold the soldering iron in one hand and the solder wire in the other, and at the same time hold the battery electrode to perform the soldering operation. This not only makes the operation extremely inconvenient and the soldering efficiency low, but also makes the battery electrode prone to tilting.

[0004] Chinese patent publication number CN213916562U discloses an auxiliary welding device for remote control circuit boards, including a base plate and an outer plate surrounding the base plate to form a circuit board limiting area. This utility model features electrode slots on the outer plate, allowing battery electrodes to be placed within the slots during welding. This eliminates the need to manually hold the battery electrodes during welding, making operation convenient and improving welding efficiency.

[0005] However, as can be seen from the accompanying drawings in the instruction manual, the circuit board is fixed only by limiting the position of the limit strip, which is not very practical and is inconvenient to use for circuit boards of different sizes. Moreover, when soldering electronic components, the user has to manually press them with tweezers, which can easily cause the components to be misaligned during the soldering process. The error rate is relatively high, and repeated errors can easily damage the circuit board and affect the soldering quality. Therefore, an auxiliary soldering device for remote control circuit boards is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an auxiliary welding device for remote control circuit boards to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a remote control circuit board auxiliary welding device, including a support frame, a support plate fixedly connected to the top of the support frame, a placement plate provided on the top of the support plate, a connecting block fixedly connected to the bottom of the placement plate, an air pump fixedly connected to the connecting block through the middle of the support plate, an adsorption hole opened on the surface of the placement plate, and a toggle plate fixedly connected to one end of the placement plate.

[0008] The support plate has a limiting groove at the top, and magnetic plates are symmetrically fixedly connected to both ends of the inner cavity of the limiting groove.

Fixed baffles are symmetrically fixedly connected to the top of the placement plate. Threaded rods are inserted into the middle of three of the fixed baffles. One end of the threaded rod is rotatably connected to a pressing plate, and the other end is fixedly connected to a rotating head.

[0009] A vertical pole is fixedly connected to one side of the top of the support plate, and a telescopic rod is rotatably connected to the top of the vertical pole. One end of the telescopic rod is equipped with a pressing mechanism.

[0010] Preferably, the support frame has a heat dissipation hole in the middle, and the input end of the air pump passes through the middle of the connecting block and is connected to the inner cavity of the placement plate.

[0011] Preferably, the cross-sectional shape of the connecting block is set to "T" shape, and the wall of the ball is in contact with the top wall of the support plate.

[0012] Preferably, the limiting slider is adapted to the limiting groove, the limiting slider is disposed in the middle of the limiting groove, a metal plate is disposed at the bottom of the limiting slider, and the limiting slider corresponds to the magnetic plate.

[0013] Preferably, the extrusion mechanism includes an insert rod inserted into one end of the telescopic rod, a pull ring fixedly connected to the top of the insert rod, and a limiting plate and a spring sleeved on the bottom end of the insert rod.

[0014] Preferably, the limiting plate is located at the end of the spring away from the pull ring, the limiting plate is fixedly connected to the insertion rod, and the bottom diameter of the insertion rod is smaller than the diameter of the insertion rod.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model firstly uses an air pump to generate suction at the top of the placement plate through the suction holes, which facilitates the adsorption of the circuit board onto the top of the placement plate, regardless of the size of the circuit board. By rotating the rotating head, the extrusion plate is controlled to extrude and fix the circuit board, which can also be used to position and fix circuit boards of different sizes, improving practicality. Furthermore, the extrusion mechanism can easily extrude and fix the electronic components that need to be soldered, preventing the components from sliding and misaligning during soldering, thus improving the soldering quality.

[0017] 2. This utility model also controls the sliding of the limiting slider within the limiting groove by pushing the toggle plate, which can change the orientation of the circuit board on the top of the placement plate. The magnetic plate and the metal plate at the bottom of the limiting slider can be used to position the limiting slider, improving the stability of the placement plate. The ball bearings further enhance the stability of the rotation of the placement plate. The uprights and telescopic rods support the extrusion mechanism while facilitating changes in the extrusion position, thus improving the performance.

[0018] In summary, through the interaction of the above-mentioned functions, it is convenient to position and fix circuit boards of different sizes, improving practicality, and it can also squeeze and fix the soldered components to avoid misalignment and improve the soldering quality.

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.

[0025] As attached Figure 1-4The remote control circuit board auxiliary welding device shown includes a support frame 1, a support plate 2 fixedly connected to the top of the support frame 1, a placement plate 3 set on the top of the support plate 2 to support the circuit board, a connecting block 9 fixedly connected to the bottom of the placement plate 3 to limit the placement plate 3 to the top of the support plate 2 and facilitate the rotation of the placement plate 3, thereby changing the orientation of the circuit board on the top of the placement plate 3 for welding purposes, a pump 10 fixedly connected through the middle of the support plate 2 to the connecting block 9, which can generate suction on the top of the placement plate 3 when the pump 10 is started, an adsorption hole 8 is opened on the surface of the placement plate 3 to facilitate the adsorption of the circuit board on the top of the placement plate 3 for welding purposes, and a toggle plate 15 fixedly connected to one end of the placement plate 3, which can be toggled and rotated by inserting a rod 18.

[0026] The top of the support plate 2 has a limiting groove 12. Magnetic plates 13 are symmetrically fixed to both ends of the inner cavity of the limiting groove 12. A limiting slider 14 is fixedly connected to the bottom of the actuating plate 15. Multiple balls 11 are provided at the bottom of the placement plate 3. By pushing the actuating plate 15, the limiting slider 14 can slide inside the limiting groove 12, thereby causing the placement plate 3 to rotate. The balls 11 improve the stability of the rotation of the placement plate 3. The magnetic plates 13 can adsorb and position the limiting slider 14, improving the usage effect.

[0027] Fixed baffles 4 are symmetrically fixed around the top of the placement plate 3. Threaded rods 5 are inserted into the middle of three of the fixed baffles 4. One end of the threaded rod 5 is rotatably connected to a pressing plate 6, and the other end is fixedly connected to a rotating head 7. The fixed baffles 4 provide convenient support. By picking up and controlling the threaded rod 5, the pressing plate 6 is driven to press the circuit board on the top of the placement plate 3, which facilitates the positioning of the circuit board and improves the usage effect.

[0028] A vertical rod 16 is fixedly connected to one side of the top of the support plate 2. A telescopic rod 17 is rotatably connected to the top of the vertical rod 16. A pressing mechanism is provided at one end of the telescopic rod 17. The vertical rod 16 supports the telescopic rod 17, which facilitates the control of the rotation of the telescopic rod 17 and the adjustment of the position of the pressing mechanism. The pressing mechanism can press and position the electronic components to be welded, which facilitates the welding process.

[0029] As attached Figure 1 , 2 As shown, the support frame 1 has a heat dissipation hole in the middle. The input end of the air pump 10 passes through the middle of the connecting block 9 and is connected to the inner cavity of the placement plate 3. The heat dissipation hole facilitates air ventilation. By starting the air pump 10, the gas inside the placement plate 3 can be extracted, so that the position of the adsorption hole 8 generates suction, which facilitates the adsorption of the circuit board on the top of the placement plate 3 and makes it easy to fix.

[0030] As attached Figure 2, 4 As shown, the cross-sectional shape of the connecting block 9 is set to "T" shape, and the wall of the ball 11 fits against the top wall of the support plate 2. The connecting block 9 facilitates the rotation of the placement plate 3 on the top of the support plate 2, and the ball 11 improves the smoothness of the rotation.

[0031] As attached Figure 2-4 As shown, the limiting slider 14 is adapted to the limiting groove 12. The limiting slider 14 is located in the middle of the limiting groove 12. A metal plate is provided at the bottom of the limiting slider 14. The limiting slider 14 corresponds to the magnetic plate 13. By sliding the limiting slider 14 inside the limiting groove 12, the stability of the rotation of the placement plate 3 is improved. With the cooperation of the magnetic plate 13 and the second metal plate, the position of the limiting slider 14 is easily positioned, thereby positioning the placement plate 3.

[0032] As attached Figure 1 , 2 As shown, the extrusion mechanism includes an insert rod 18 inserted into one end of the telescopic rod 17, a pull ring 21 fixedly connected to the top of the insert rod 18, and a limiting plate 19 and a spring 20 sleeved on the bottom end of the insert rod 18.

[0033] As attached Figure 1 , 2 As shown, the limiting plate 19 is located at the end of the spring 20 away from the pull ring 21. The limiting plate 19 is fixedly connected to the insertion rod 18. The bottom diameter of the insertion rod 18 is smaller than the diameter of the insertion rod 18. By pushing the limiting plate 19 with the spring 20, the insertion rod 18 can generate a squeezing force on the bottom. By pulling the spring 20, the insertion rod 18 can be easily moved upward, making it convenient to move and use.

[0034] The working principle of this utility model is as follows: When in use, the circuit board is placed on the top of the placement plate 3. The extrusion plate 6 can be controlled by rotating multiple rotating heads 7 to extrude and position the circuit board on the top of the placement plate 3. Alternatively, the air pump 10 can be started to generate suction inside the adsorption hole 8 to adsorb the circuit board on the top of the placement plate 3.

[0035] During soldering, place the electronic component in the preset position on the circuit board, then rotate and pull the plug rod 18 to rotate and extend one end of the telescopic rod 17 until the plug rod 18 is directly above the electronic component. Then release the pull on the plug rod 18 to press and fix the plug rod 18 against the electronic component, which facilitates soldering.

[0036] When it is necessary to change the placement orientation of the circuit board, the insertion rod 18 is moved away from the top of the placement plate 3, and then the limit slider 14 is moved from one magnetic plate 13 to another magnetic plate 13 when the toggle plate 15 is pushed. The magnetic plate 13 is used for positioning to change the placement orientation of the circuit board, which is convenient for auxiliary soldering.

[0037] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
