Description

Technical Field

[0001] This utility model relates to the field of electronic component processing technology, and in particular to an integrated device for inductor coil lead cutting, soldering testing and coding. Background Technology

[0002] Inductors play a crucial role in various circuit systems and are widely used. One type of inductor on the market consists of a pair of coils wound one turn after another around a circular toroidal coil. The toroidal coil is an insulating tube that insulates the coils from each other. After a certain number of turns, four leads are provided. To increase inductance, an iron core or magnetic powder core is usually placed inside the toroidal coil. These inductors are classified into three main categories based on their shape: inductors without a base or base plate, inductors with a base plate (such as...). Figure 1 (as shown in (a)) and inductors with bases (such as Figure 1 (as shown in (b)).

[0003] The manufacturing process of inductors typically involves the following steps: dispensing, baking, lead cutting, soldering, withstand voltage testing, inductance testing, and coding. In the existing technology, utility model patent CN206451600U discloses an integrated automatic soldering and testing machine for inductors. This machine processes inductors after lead cutting, including soldering, withstand voltage testing, and inductance testing, but the number of steps is limited. Furthermore, it is only suitable for inductors without a base / plate, not for inductors with a base / plate. Moreover, if the inductor comes from a product that has undergone dispensing and baking, the relative position of the product may shift due to vibrations during baking on the loading tray. Without position correction, this will significantly impact continuous production. Therefore, there is an urgent need for an integrated inductor lead cutting, soldering, testing, and coding device that can solve the above problems. Utility Model Content

[0048] In order to make the technical problems, technical solutions and advantages to be solved by the utility model more clear, the following will be described in detail in combination with the drawings and specific embodiments.

[0049] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0050] The utility model provides a kind of inductance coil cut foot soldering test coding integrated equipment, as shown in figure, including workbench 18, wherein: Figures 2-3

[0051] One end of workbench 18 is provided with the feeding baking tray 1 for conveying the inductance coil 17 to be processed, and the other end is provided with the discharging belt 16;

[0052] Workbench 18 is sequentially provided with feeding correction positioning device 2, cutting foot machine 4, soldering device, voltage withstand test mechanism 8, inductance test mechanism 11 and coding mechanism 13 between feeding baking tray 1 and discharging belt 16, the side of feeding correction positioning device 2 and cutting foot machine 4 is provided with feeding and cutting foot mechanical arm 3, the side of soldering device and voltage withstand test mechanism 8 is provided with soldering and voltage withstand test mechanical arm 7, the side of inductance test mechanism 11 is provided with inductance test mechanical arm 10, and coding mechanism 13 includes coding discharging mechanical arm 14 and coding machine 15 oppositely arranged with coding discharging mechanical arm 14;

[0053] Feeding correction positioning device 2 includes mounting seat 21, mounting seat 21 is provided with fixed stand 22, fixed stand 22 is provided with support seat 23 for placing inductance coil 17 to be processed and extending in the length direction of inductance coil base / bottom plate 171 in the form of a Chinese character, magnet (not shown) is embedded in support seat 23, the length direction of support seat 23 is provided with clamping device on both sides, clamping device includes opening cylinder 24 arranged on mounting seat 21, both ends of opening cylinder 24 are provided with positioning clamp fixing support 25 and positioning clamp 26 for clamping inductance coil base / bottom plate 171 at the end of positioning clamp fixing support 25.

[0054] ​In use, the loading and cutting robotic arm 3 first picks up the inductor coil 17 to be processed from the loading baking tray 1 and places it into the loading and straightening positioning device 2. The support base 23 of the loading and straightening positioning device 2 is embedded with a magnet. The magnet attracts the inductor coil 17 to be processed onto the support base 23. Then, the open cylinder 24 closes and drives the positioning clamp 26 to clamp the base / bottom plate 171 of the inductor coil 17 to the preset position on the loading and straightening positioning device 2. In this way, the position of the inductor coil 17 to be processed is corrected by the magnet and the positioning clamp 26. After that, the loading and cutting robotic arm 3 clamps the inductor coil 17 to be processed onto the cutting machine 4. After the cutting is completed, the soldering and withstand voltage testing robotic arm 7 clamps the inductor coil 17 to be processed and passes it through the soldering device and the withstand voltage testing mechanism 8 to complete the soldering and withstand voltage testing. During the testing process, if the withstand voltage test of the inductor coil 17 to be processed fails, it is placed in the withstand voltage defective product collection box 9; if the withstand voltage test of the inductor coil 17 to be processed passes, the inductor testing robot arm 10 transports it to the inductor testing mechanism 11 for inductance testing. Similarly, if the inductance test of the inductor coil 17 to be processed fails, it is placed in the inductor defective product collection box 12; if the inductance test of the inductor coil 17 to be processed passes, the coding and unloading robot arm 14 clamps the inductor coil 17 to be processed for coding. Finally, the coded inductor coil 17 is transported to the unloading belt 16, which transports it out. Repeating the above process completes the production.

[0055] There are usually multiple inductor coils 17 to be processed on the feeding baking tray 1, such as Figures 4-5 As shown, the relative position of the inductor coil 17 to be processed changes due to the bumps during baking on the feeding tray 1. Therefore, the relative position needs to be adjusted before feeding. When the feeding and cutting robot arm 3 grips the coil, it can adjust the position of the inductor coil 17 in the Y-axis direction and place it on the feeding correction and positioning device 2. The positioning clamp 26 clamps the coil 17 symmetrically and pushes it to the center of the gripper relative to the feeding and cutting robot arm 3 to adjust its position in the X-axis direction. In this way, when the gripper of the feeding and cutting robot arm 3 picks up the inductor coil 17 again, the center of the inductor coil 17 is relatively coincident with the center of the two grippers of the feeding and cutting robot arm 3, thus completing the position correction.

[0056] The inductance coil foot cutting, soldering, testing, coding and marking integrated equipment can realize flexible production, and is provided with a feeding correcting positioning device, a foot cutting machine, a soldering device, a voltage resistance testing mechanism, an inductance testing mechanism and a coding mechanism between the feeding baking tray and the discharging belt in sequence, the feeding correcting positioning device and the foot cutting machine are provided with a feeding and foot cutting mechanical arm on the side surface, the soldering device and the voltage resistance testing mechanism are provided with a soldering and voltage resistance testing mechanical arm on the side surface, and the inductance testing mechanism is provided with an inductance testing mechanical arm on the side surface, so that the foot cutting, soldering, voltage resistance testing, inductance testing and coding of the inductance coil to be processed can be realized automatically through cooperation of the mechanical arms and the foot cutting machine, the soldering device, the voltage resistance testing mechanism, the inductance testing mechanism and the coding mechanism, the process is covered and the use is convenient.

[0057] As shown in Figure 3 For the convenience of component installation and the improvement of positioning accuracy, a positioning clamp adapter plate 27 can be arranged between the positioning clamp fixing support 25 and the positioning clamp 26, and the positioning clamp adapter plate 27 is provided with a vertical extension long strip fixing hole 271 in which a fixing screw (not shown in the figure) for fixing the positioning clamp adapter plate 27 to the positioning clamp fixing support 25 is arranged.

[0058] The positioning clamp 26 is provided with a long strip fixing hole 261 extending along the length direction of the support seat 23, and the long strip fixing hole 261 is provided with a fixing screw (not shown in the figure) for fixing the positioning clamp 26 to the positioning clamp adapter plate 27; the positioning clamp adapter plate 27 is provided with a vertical extension long strip fixing hole 271, and the long strip fixing hole 271 is provided with a fixing screw (not shown in the figure) for fixing the positioning clamp adapter plate 27 to the positioning clamp fixing support 25.

[0059] The long strip fixing hole 261 can move the positioning clamp 26 in the length direction of the support seat 23, and the long strip fixing hole 271 can move the positioning clamp 26 in the vertical direction, so that the position of the positioning clamp 26 can be adjusted according to different models of the inductance coil to be processed 17, and the positioning clamp 26 can accurately clamp the base / plate 171 of the inductance coil to be processed 17.

In this way, the position of the inductor coil can be better ensured not to change, and the continuous production is better facilitated.

[0063] The pin trimmer 4 can further be provided with a sensor mounting plate 43, and the sensor mounting plate 43 is provided with a photoelectric sensor 44 for detecting whether the inductor coil 17 to be trimmed exists on the pin trimmer 4.

[0064] At this time, the working process of the pin trimmer 4 can be as follows:

[0065] The photoelectric sensor 44 detects whether the inductor coil 17 to be trimmed exists on the pin trimmer 4, and after it is determined that there is no inductor coil 17 to be trimmed, the loading and trimming mechanical arm 3 clamps the inductor coil 17 to be trimmed from the loading correction positioning device 2 to the pin trimmer 4, the rotary pressing cylinder 41 controls the pressing plate 42 to rotate and press down, so as to position the inductor coil 17 to be trimmed, and then the pin trimmer 4 is started to trim and shape the PIN feet of the inductor coil 17 to be trimmed to the specified PIN distance and PIN length, and the rotary pressing cylinder 41 controls the pressing plate 42 to rise and rotate back to the original position.
