Description

Technical Field

[0001] The invention belongs to the field of high-frequency transformer production equipment, and in particular relates to high-frequency transformer soldering equipment. Background Art

[0002] A high-frequency transformer is a power transformer with an operating frequency exceeding the medium frequency (10kHz). It is mainly used as a transformer in high-frequency switching power supplies. Some are also used as transformers in high-frequency inverter power supplies and high-frequency inverter welding machines. According to the operating frequency, it can be divided into several grades: 10kHz~50kHz, 50kHz~100kHz, 100kHz~500kHz, 500kHz~1MHz, and above 10MHz.

[0003] A high-frequency transformer consists of an iron core (or magnetic core) and a coil, which includes two or more "E"-shaped windings. The production of a high-frequency transformer primarily involves winding on a spool, wrapping with adhesive tape, wiring, soldering, assembly, inductance testing, wrapping with copper tape, testing, calibration, and packaging.

[0004] The current soldering process involves using a clamp to hold a high-frequency transformer and inserting the leads into a solder pot. The pot temperature is pre-set to 450-500°C, and the leads are soldered for 2-4 seconds before being removed. However, since the clamp can only solder one lead at a time, this is extremely inefficient. Furthermore, due to the high temperature of the molten solder, workers' hands are often too close to the pot during soldering, posing a potential safety hazard and easily getting burned.

[0005] To address this situation, the patent application number "CN201520049273.5" discloses a high-frequency transformer line end tinning device, which includes a tin pool and an intermediate rod. The interior of the two ends of the intermediate rod are respectively connected to retractable left and right hand-held rods. A plurality of clamping blocks are fixedly connected to the side of the intermediate rod facing the tin pool. Among the multiple clamping blocks, the bottoms of two adjacent clamping blocks have integrally connected limit blocks on the opposite side.

[0006] This device inserts a high-frequency transformer between multiple clamps on an intermediate rod, which not only prevents the high-frequency transformer from falling into the tin pool due to loose bonding and resulting in waste, but also ensures the high-frequency transformer is highly consistent, eliminating the phenomenon of under- or over-immersion. During operation, it is only necessary to hold the left and right hand rods so that the exposed terminal is immersed in the tin pool. The length of the left and right hand rods can be adjusted according to actual operation needs, making it very convenient to use. However, when soldering the high-frequency transformer, the device still requires manual operation of the hand rods, which can easily cause burns to the operator during manual operation. At the same time, after the high-frequency transformer pins are tinned, the high-frequency transformer needs to be manually removed, which reduces work efficiency. Summary of the Invention

[0007] The present invention aims to provide a high-frequency transformer soldering device to realize automatic tinning of high-frequency transformer pins and removal after tinning.

[0008] The high-frequency transformer soldering equipment in this scheme includes a support frame and a placement rod, and the placement rod is provided with multiple placement holes for placing the high-frequency transformer; the support frame is provided with a tin pool for soldering the high-frequency transformer, and two circulating transmission mechanisms are arranged on the support frame. The transmission mechanism is in a "concave" shape, and the two transmission mechanisms are respectively located on both sides of the tin pool, and the opposite sides of the transmission mechanism are provided with blocks for placing the placement rod.

[0009] The working principle and beneficial effects of this solution are as follows: During use, multiple high-frequency transformers are placed in the mounting holes of the mounting rods, with the pins of the high-frequency transformers extending out of the mounting holes, with the length of the pins extending out of the mounting holes being no less than the required tinning height. The ends of the mounting rods are then secured in corresponding blocks of two transmission mechanisms. The transmission mechanism is then activated, and during transmission, the mounting rods are moved. During movement, when the mounting rods are not in contact with the tin pool, they are in a higher position and do not come into contact with the support frame. When they reach the tin pool, their lower position allows the pins of the high-frequency transformers to enter the tin pool for soldering. Simultaneously, the transmission mechanism's transmission speed is controlled to ensure that the pins of the high-frequency transformers remain in the tin pool for a period of 2 to 4 seconds. Because the transmission mechanism is looped around the support frame, after the pins of the high-frequency transformers are soldered, the transmission mechanism continues to drive the mounting rods. When the mounting rods move below the support frame, the high-frequency transformers are positioned below the mounting rods. Gravity then causes the soldered high-frequency transformers to automatically fall out of the mounting holes of the mounting rods, achieving automatic detachment of the high-frequency transformers. The high-frequency transformer soldering equipment in this solution realizes the automatic soldering and removal of the high-frequency transformer pins by setting a transmission mechanism, which cooperates with the placement rod. While ensuring the safety of the staff, it improves the soldering efficiency of the high-frequency transformer.

[0010] Furthermore, a collection basket for collecting high-frequency transformers is provided below the support frame, which facilitates the unified collection of high-frequency transformers and improves work efficiency.

[0011] Furthermore, the block is provided with a slot, in which a card is placed for securing the placement rod. The card prevents the placement rod from falling after being moved to the support frame and lowered, thereby reducing damage to the high-frequency transformer caused by the placement rod falling; and the card does not adversely affect manual handling of the placement rod.

[0012] Furthermore, the support frame is provided with a motor for driving the transmission mechanism. In order to reduce the number of transmission components between the motor and the transmission mechanism, the motor is preferably a dual-axis motor.

[0013] Furthermore, a plurality of stop blocks are fixedly connected to opposite sides of the two transmission mechanisms, each of which has a plurality of stop holes formed in the vertical direction thereof, and the clamping block is detachably connected to the stop block via the stop holes. During the soldering process of the high-frequency transformer pins, the liquid level of the tin in the tin pool changes over time. By providing the stop blocks and adjusting the position of the clamping block on the stop blocks, the height of the placement rod can be adjusted, thereby satisfying the soldering requirements of the high-frequency transformer pins at different liquid levels in the tin pool.

[0014] Furthermore, both transmission mechanisms include a chain and a plurality of sprockets used therewith, the plurality of sprockets being rotatably connected to the support frame; the limit blocks are provided on opposite sides of the two chains; and the sprockets are driven by a motor. By using a sprocket and chain transmission method, the overall structure of the transmission mechanism is simpler, more reliable, and has a lower investment cost.

[0015] Furthermore, both transmission mechanisms include a conveyor belt and a plurality of drive wheels used in conjunction therewith, the plurality of drive wheels being rotatably connected to the support frame; the limit blocks are provided on opposite sides of the two conveyor belts; and the drive wheels are driven by a motor. The use of drive wheels and conveyor belts makes the overall structure of the transmission mechanism simpler and more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 3 for Figure 2 Schematic diagram of the structure after the card block and the limit block are connected. DETAILED DESCRIPTION

[0019] The following is further described in detail through specific implementation methods:

[0020] The reference numerals in the drawings of the specification include: support frame 1, conveyor belt 2, transmission wheel 3, rotating shaft 4, belt 5, placement rod 6, placement hole 7, tin pool 8, limit block 9, card block 10, card 11, collection basket 12, limit hole 13.

[0021] Example 1 is basically as shown in the attached Figures 1 to 3As shown: high-frequency transformer soldering equipment, including a support frame 1 and a placement rod 6, the placement rod 6 is provided with a plurality of placement holes 7 for placing high-frequency transformers; a tin pool 8 for soldering the high-frequency transformer is provided on the top of the support frame 1, and a collection basket 12 for collecting the high-frequency transformer is provided below the support frame 1. Two circulating transmission mechanisms are provided on the support frame 1, and the two transmission mechanisms are driven by the same motor; the transmission mechanism includes a conveyor belt 2 and a plurality of transmission wheels 3 used therewith, and the plurality of transmission wheels 3 are rotatably connected to the support frame 1 through a rotating shaft 4, and the conveyor belt 2 is connected to the transmission wheel 3 to form a "concave" shape. " shape, the two conveyor belts 2 are respectively located on both sides of the tin pool 8; a plurality of limit blocks 9 are provided on the opposite sides of the two conveyor belts 2, and a plurality of limit holes 13 are provided in the vertical direction of the limit blocks 9. The limit blocks 9 are detachably connected with a clamping block 10 by screws, and the clamping block 10 is fixed at the limit hole 13. The clamping block 10 is provided with a slot, and a card 11 for fixing the placement rod 6 is provided in the slot; the motor is a double-axis motor, and the two output shafts of the double-axis motor are respectively connected to the rotating shaft 4 on both sides of the tin pool 8 through a belt 5. The rotation of the rotating shaft 4 drives the transmission wheel 3 connected thereto to rotate, and the rotation of the transmission wheel 3 drives the conveyor belt 2 to transmit.

[0022] The specific implementation process is as follows: During use, adjust the position of the clamping block 10 on the stopper block 9 and determine the height of the clamping block 10 relative to the molten tin liquid level to meet the soldering height of the high-frequency transformer pins. The high-frequency transformer is placed through the mounting hole 7 of the mounting rod 6. The mounting rod 6 is then secured in the slot of the clamping block 10. The clamping card 11 in the slot secures the mounting rod 6. The dual-axis motor is activated, which drives the belt 5 connected to it. The belt 5 drives the drive wheel 3 connected to it, which drives the conveyor belt 2. The conveyor belt 2 drives the mounting rod 6, thereby moving the mounting rod 6. When the mounting rod 6 moves to the tin pool 8, the high-frequency transformer pins enter the molten tin, allowing soldering to be applied to the high-frequency transformer pins. After soldering, the high-frequency transformer pins move below the support frame 1. At this point, the high-frequency transformer is located below the mounting rod 6. After soldering, the high-frequency transformer falls under gravity into the collection basket 12. However, the mounting rod 6 is prevented from falling due to the securing action of the clamping card 11. When the mounting rod 6 is needed to secure the high-frequency transformer, it can be manually removed.

[0023] The only difference between Example 2 and Example 1 is that the conveyor belt 2 and transmission wheel 3 of the transmission mechanism are replaced by chains and sprockets, and multiple sprockets are rotatably connected to the support frame 1; the limit blocks 9 are set on opposite sides of the two chains; and the sprockets are driven by a dual-axis motor.
