Description

Technical Field

[0001] This utility model relates to the field of diode welding technology, and in particular to a diode connection auxiliary structure. Background Technology

[0002] A through-hole diode is a type of diode that is directly inserted into a hole in a circuit board and fixed in place. This type of diode is very common in electronic circuits, especially in situations where manual soldering or repair is required. In the use of through-hole diodes, the terminals need to be soldered to the circuit board. Due to the small size of the diode, auxiliary structures are used to assist in soldering the circuit board and the diode in order to improve connection efficiency.

[0003] A search revealed Chinese Patent Publication No. CN216503211U, which discloses a diode welding auxiliary device. The device includes a support plate for mounting a diode, a first limiting plate slidably mounted on the side wall of the support plate, and a second limiting plate slidably mounted on the end of the first limiting plate. Sliding the first and second limiting plates fixes the support plate to the circuit board. Multiple diodes are then fixed using the support plate to assist welding. After the diodes are fixed, welding is performed on the side of the circuit board away from the support plate. Compared to using tweezers to fix the diodes, this significantly improves welding efficiency.

[0004] In actual use, the aforementioned diode connection auxiliary structure requires multiple limiting plates to clamp and fix the circuit board. To ensure the stability of the clamping, limiting plates need to be set around the circuit board. This means that when assisting in the installation or removal of the circuit board, it is necessary to operate the limiting plates on all four sides simultaneously, which is difficult for a single person to complete. This significantly increases the difficulty of using the auxiliary structure. Therefore, a diode connection auxiliary structure is proposed to solve the above problems. Utility Model Content

[0012] The moving unit includes a screw, which is rotatably connected to the upper surface of the clamping plate. Limiting rods are fixedly connected to both the left and right sides of the upper surface of the clamping plate.

[0013] As a further description of the above technical solution:

[0014] The upper ends of both the screw and the limiting rod pass through the U-shaped frame, and the screw and the U-shaped frame are threaded together.

[0015] As a further description of the above technical solution:

[0016] A circular plate is fixedly connected to the top end of the screw, and a support plate is fixedly connected to the top end of the limiting rod.

[0030] 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.

[0031] Reference Figures 1-2This utility model provides an embodiment of a diode connection auxiliary structure, including a circuit board 1. A through-hole diode 2 is inserted into the top of the circuit board 1. A insertion hole is provided on the top of the circuit board 1, through which the through-hole diode 2 is inserted into the circuit board 1. Then, the electrode leads of the through-hole diode 2 can be soldered to the circuit board 1 to complete the installation of the through-hole diode 2. A U-shaped frame 3 is fitted onto the outer side of the circuit board 1. A clamping plate 4 is provided inside the U-shaped frame 3. A rubber pad 5 is fixedly connected to the bottom surface of the clamping plate 4. When moved, the rubber pad 5 can move synchronously. The inner wall surfaces on the left and right sides of the U-shaped frame 3 are mirrored and detachably connected to two L-shaped plates 6. The end of the circuit board 1 is located inside the L-shaped plate 6. When the circuit board 1 is placed on the L-shaped plate 6, the L-shaped plate 6 will support the circuit board 1 and provide initial positioning, so that the circuit board 1 is stably placed inside the U-shaped frame 3. Different sizes of L-shaped plates 6 can be replaced according to different batches of circuit boards 1 to support the circuit board 1, reducing the obstruction of the bottom surface of the circuit board 1 while providing stable support for the circuit board 1.

[0032] Reference Figures 1-3 A baffle 7 is fixedly connected to the back of the U-shaped frame 3. When placing the circuit board 1, the circuit board 1 can be placed on the L-shaped plate 6 first, and then the circuit board 1 can be pushed to make the circuit board 1 fit against the baffle 7, further limiting the position of the circuit board 1. A moving unit is provided above the clamping plate 4. The moving unit includes a screw 41, which is rotatably connected to the upper surface of the clamping plate 4. When the screw 41 moves up and down, it can drive the clamping plate 4 to move synchronously. The left and right sides of the upper surface of the clamping plate 4 Both are fixedly connected to a limiting rod 43, which can guide and limit the movement of the clamping plate 4, so that the clamping plate 4 can only move in a straight line in the up and down direction. The upper ends of the screw 41 and the limiting rod 43 are both inserted through the U-shaped frame 3. The screw 41 and the U-shaped frame 3 are threadedly connected. When the screw 41 rotates, it can move in the up and down direction relative to the U-shaped frame 3. At the same time, it can drive the clamping plate 4 to move up and down synchronously under the limitation of the limiting rod 43. It can be operated by a single person, reducing the difficulty of operation.

[0033] A circular plate 42 is fixedly connected to the top of the screw 41, and a support plate 44 is fixedly connected to the top of the limiting rod 43. An anti-slip groove is provided on the outer surface of the circular plate 42. The operator can rotate the screw 41 through the circular plate 42 to facilitate screwing. The anti-slip groove increases the friction between the outer wall of the circular plate 42 and the operator's hand to prevent slippage. The upper surface of the circular plate 42 and the upper surface of the support plate 44 are on the same horizontal plane. After the clamping plate 4 moves down to clamp and limit the circuit board 1 and the through-hole diode 2, the U-shaped frame 3 can be inverted, so that the bottom surface of the circuit board 1 and the lead wire of the through-hole diode 2 are flipped to the top for easy soldering. At this time, the circular plate 42 and the support plate 44 can increase the contact area between the bottom surface of the device and the placement platform, making the device more stable after inversion and improving the stability during soldering.

[0034] Reference Figure 2 and Figure 4 The inner walls of the left and right sides of the U-shaped frame 3 are fixedly connected to the limiting housings 8. The bottom surface of the L-shaped plate 6 is fixedly connected to the side plate 9. When the L-shaped plate 6 moves, it can drive the side plate 9 to move synchronously. The side plate 9 is fixedly connected to the U-shaped frame 3 by bolts 10. The two side plates 9 on the left and right sides of the U-shaped frame 3 are respectively inserted into the interior of the two limiting housings 8 on the left and right sides of the U-shaped frame 3. When different L-shaped plates 6 need to be installed, the bottom end of the side plate 9 can be inserted into the interior of the limiting housing 8 for preliminary limiting, so that the bolts 10 can be quickly aligned with the screw holes on the surface of the side plate 9, which is convenient for the installation of the L-shaped plate 6. The operation is simple. When the L-shaped plate 6 needs to be replaced for different specifications of circuit boards 1, the fixing of the L-shaped plate 6 and the side plate 9 can be released by simply unscrewing the bolts 10. The operation is simple and convenient for replacement.

[0035] Working principle: After all the through-hole diodes 2 that need to be soldered are inserted into the circuit board 1, the circuit board 1 is placed on the L-shaped plate 6 to initially limit the circuit board 1. Then, the circuit board 1 is pushed back so that it fits against the baffle 7. As the circular plate 42 is turned, the screw 41 rotates, which in turn moves the clamping plate 4 and the rubber pad 5 downward under the limit of the limiting rod 43. Together with the L-shaped plate 6, the circuit board 1 and the through-hole diodes 2 are limited. This can be operated by a single person, improving the efficiency of auxiliary limiting and preventing the through-hole diodes 2 from detaching from the circuit board 1 during the soldering process. At the same time, all the through-hole diodes 2 are inserted and limited, improving the soldering efficiency. Then, the U-shaped frame 3 can be inverted so that the bottom surface of the circuit board 1 and the leads of the through-hole diodes 2 are flipped to the top for easy soldering. The circular plate 42 and the support plate 44 can increase the contact area between the bottom surface of the structure and the platform, making the device more stable after inversion and improving the stability during soldering.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
