[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 ring. The ring 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 ring.

[0003] In existing technologies, such as Figure 1 The inductor coil with base (i.e., base plate) shown needs to be mounted on the plate during production. Currently, this is usually done manually, which is labor-intensive and inefficient. Summary of the Invention

Detailed Implementation

[0040] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0041] In the prior art, there is an inductor coil (such as...) Figure 1 The winding diameter of the inductor shown in (a) is relatively thick, and its connection end can be tinned for direct use as a pin. When mounting this type of inductor, the pin of the inductor is first passed through the base plate (e.g., Figure 1 The pin sockets on the inductor coil (as shown in (b) and (c)) are then bent to temporarily fix the inductor coil after it passes through the base plate. This gives the inductor coil on the upper board (as shown in (b) and (c)). Figure 1 (as shown in d).

[0042] To perform the mounting operation on the aforementioned inductor coil, this invention provides a method for mounting the inductor coil base plate using a mounting mechanism, such as... Figure 2-6 As shown, the inductor coil base plate mounting mechanism includes a mounting base 500. The mounting base 500 has a base plate receiving groove 300 for accommodating the base plate 200 of the inductor coil 100. Above the base plate receiving groove 300, there is a pressing device for pressing down the inductor coil 100 so that the leads 101 of the inductor coil 100 pass through the lead insertion holes 201 on the base plate 200. Below the base plate receiving groove 300, there is a support for the base plate 200. The bracket 22 includes a left bracket 221 and a right bracket 222 that can be separated (i.e., separated and closed). The width of the left bracket 221 and the right bracket 222 after being closed is less than the distance between the pin insertion holes 201 on both sides of the base plate 200. The fixing base 500 is provided with a first driving device for driving the left bracket 221 and the right bracket 222 to separate so as to bend (i.e. pull into a figure-eight shape) the pin 101 of the inductor coil 100 after passing through the base plate 200.

[0043] The method includes:

[0044] Step 1: Place the base plate 200 into the base plate receiving groove 300;

[0045] Step 2: Align the pins 101 of the inductor coil 100 with the pin sockets 201 of the base plate 200, and use the pressing device to press down the inductor coil 100 so that the pins 101 of the inductor coil 100 pass through the pin sockets 201 on the base plate 200.

[0046] Step 3: Use the first driving device to drive the left bracket 221 and the right bracket 222 to separate them so as to bend the pin 101 of the inductor coil 100 after it passes through the base plate 200;

[0047] In this step, the left bracket 221 and the right bracket 222 are separated so that the pin 101 of the inductor coil 100 after passing through the base plate 200 is bent. The drive device can then be reset. After the reset is completed, the inductor coil 100 is removed, and the production of the next product (the inductor coil to be installed on the board) can proceed.

[0048] It is conceivable that the pins of the inductor coil 100 can be a pair (2) or two pairs (4). In this embodiment, the pins of the inductor coil 100 are two pairs, located on both sides of the inductor coil 100 ring. Correspondingly, the pin sockets 201 on the base plate 200 are also two pairs (4) and symmetrically distributed on both sides of the length direction of the base plate 200.

[0049] In this application, the inductor coil 100 has two sets of windings, and the two connecting ends of each set of windings are used as pins 101. The diameter of the windings / pins 101 is preferably 1.0-2.5mm, which has a certain strength and can be directly used as PINs.

[0050] The present invention utilizes an inductor coil base plate mounting mechanism for mounting. A pressing device presses down the inductor coil so that the inductor coil leads pass through the lead insertion holes on the base plate. A first driving device drives the left and right brackets to separate, bending the leads of the inductor coil after passing through the base plate. Compared with manual operation, this method reduces the workload of manual mounting, improves efficiency, and better ensures product quality.

[0051] To facilitate bending the pin 101 of the inductor coil 100 after it passes through the base plate 200 using the left bracket 221 and right bracket 222, and to save effort, the present invention can have the following structural forms depending on the structure:

[0052] Structural form one (such as) Figure 6 As shown in (a): The outer surfaces (i.e., the ends that are far apart from each other) of the left bracket 221 and the right bracket 222 can both be inclined surfaces 2211 and 2221 that gradually thicken from top to bottom;

[0053] Structural Form Two (e.g.) Figure 6 As shown in (b): The lower middle part of the outer side of the left bracket and the right bracket can be provided with slopes 2211 and 2221 that gradually thicken from top to bottom. This structure applies force to the far end of the pin 101 after the inductor coil 100 passes through the base plate 200. Compared with the previous structure, it can avoid the near end of the pin 101 close to the pin socket 201 of the base plate 200 being blocked by the pin socket 201, and makes it easier to bend the pin 101.

[0054] The first driving device for separating the left bracket 221 and the right bracket 222 can adopt various structural forms readily conceived by those skilled in the art. For example, the first driving device can be a single cylinder, with its two ends driving the left and right brackets respectively. However, for ease of implementation, the first driving device in this invention preferably includes a left bracket cylinder 34 for driving the left bracket 221 and a right bracket cylinder 36 for driving the right bracket 222. In this case, the left bracket 221 can be driven by the left bracket cylinder 34, and the right bracket 222 can be driven by the right bracket cylinder 36.

[0055] The pressing device for pressing down the inductor coil 100 can also adopt various structural forms readily conceived by those skilled in the art. The pressing device in this invention is preferably a pressing cylinder 1. In the embodiment shown in the figure, the fixing base 500 may include an upper fixing plate 7 (workbench panel), a middle fixing plate 37 (support cylinder fixing plate), and a lower fixing plate 45 (base plate). A support column 38 may be provided between the middle fixing plate 37 and the upper fixing plate 7, and a support column 44 may be provided between the lower fixing plate 45 and the upper fixing plate 7. A cylinder bracket may be provided on the upper fixing plate 7, and the pressing cylinder 1 is fixed on the cylinder bracket. The bracket 22 and the first driving device are both located on the middle fixing plate 37. The cylinder bracket is preferably Z-shaped and includes a first horizontal plate 2, a vertical plate 3, and a second horizontal plate 5 from top to bottom. The pressing cylinder 1 is fixed on the first horizontal plate 2 to avoid operating space. A rubber pressure block 4 may be provided at the output end of the pressing cylinder 1 to prevent damage to the inductor coil 100 during the pressing process.

[0056] To facilitate guiding, temporarily supporting, and fixing the inductor coil 100, and to ensure that the leads 101 of the inductor coil 100 accurately pass through the lead insertion holes 201 on the base plate 200, the mounting base 500 (i.e., the upper mounting plate 7) may be provided with a detachable (i.e., open and close) left lead plate 20 and right lead plate 30 on both sides above the base plate receiving groove 300. The mounting base 500 is provided with a second driving device for driving the left lead plate 20 and right lead plate 30 to open and close. The opposite ends of the left lead plate 20 and right lead plate 30 Half-hole slots are provided on both surfaces. When the left lead plate 20 and the right lead plate 30 are closed together, the half-hole slots are engaged to form a guide socket 400 for guiding the pin 101 of the inductor coil 100. At this time, the position of the guide socket 400 corresponds to the position of the pin socket 201 on the bottom plate 200 inside the bottom plate receiving slot 300 (the guide socket 400 is located directly above the pin socket 201, and the two are aligned and preferably coaxial). The upper surfaces of the left lead plate 20 and the right lead plate 30 form a temporary support surface for the inductor coil 100.

[0057] At this point, step 2 above is further described as follows: the pins 101 of the inductor coil 100 are aligned and inserted into the guide socket 400 formed by the closed left guide plate 20 and right guide plate 30. The left guide plate 20 and right guide plate 30 are driven to separate by the second driving device, and the inductor coil 100 is pressed down by the pressing device so that the pins 101 of the inductor coil 100 pass through the pin socket 201 on the base plate 200.

[0058] In this step, the manual switch 12 can be pressed for the first time (e.g., turning on the foot switch and pressing down the foot switch). The second drive device drives the left guide plate 20 and the right guide plate 30 to close together to form a guide socket 400. Then, the pin 101 of the inductor coil 100 is aligned and inserted into the guide socket 400 formed by the closed left guide plate 20 and the right guide plate 30. The manual switch 12 is pressed for the second time. The second drive device drives the left guide plate 20 and the right guide plate 30 to separate. At the same time, the pressing device presses down the inductor coil 100 so that the pin 101 of the inductor coil 100 passes through the pin socket 201 on the base plate 200 to the predetermined position.

[0059] To ensure that the pins 101 of the inductor coil 100 pass more precisely through the pin sockets 201 on the base plate 200, the opposing end faces of the left lead plate 20 and the right lead plate 30 can be mutually mating first and second fracture surfaces, respectively. The first fracture surface sequentially includes a first protrusion 2021, a first groove 2022, a second protrusion 2023, and a second groove 2024. The second fracture surface sequentially includes a third groove 3021 that mates with the first protrusion 2021, a third protrusion 3022 that mates with the first groove 2022, a fourth groove 3023 that mates with the second protrusion 2023, and a fourth protrusion 3024 that mates with the second groove 2024. 24. The first groove 2022, the second groove 2024, the third groove 3021, and the fourth groove 3023 are all provided with semi-hole slots. When the left guide plate 20 and the right guide plate 30 are closed together, the first protrusion 2021 is located within the third groove 3021, the second protrusion 2023 is located within the fourth groove 3023, the third protrusion 3022 is located within the first groove 2022, and the fourth protrusion 3024 is located within the second groove 2024. The semi-hole slots on the first protrusion 2021, the second protrusion 2023, the third protrusion 3022, and the fourth protrusion 3024 respectively engage with the semi-hole slots in the third groove 3021, the fourth groove 3023, the first groove 2022, and the second groove 2024 to form two pairs (four) of guide holes 400. The guide holes 400 are preferably tapered holes, larger at the top and smaller at the bottom, to facilitate the insertion of the pins 101 of the inductor coil 100.

[0060] To better guide, temporarily support, and fix the inductor coil 100, the thickness of both the left lead plate 20 and the right lead plate 30 is preferably less than the length of the pin 101 of the inductor coil 100 and greater than half the length of the pin 101 of the inductor coil 100. In this case, the inductor coil 100 can be relatively stably inserted into the guide socket 400 without tilting. The thickness can be 0.5-1.5cm.

[0061] The second driving device for driving the left guide plate 20 and the right guide plate 30 to separate and engage can adopt various structural forms that are easily conceived by those skilled in the art. However, for ease of implementation, the second driving device in this invention preferably includes a left guide cylinder 14 that drives the left guide plate 20 and a right guide cylinder 9 that drives the right guide plate 30. In this case, the left guide plate 20 can be driven by the left guide cylinder 14 and the right guide plate 30 can be driven by the right guide cylinder 9.

[0062] To facilitate the guidance and positioning of the guide plates 20 and 30, a left guide rail 21 and a right guide rail 33 can be respectively provided on both sides of the base plate receiving groove 300 on the fixing base 500 (i.e., the upper fixing plate 7). The left guide plate 20 is slidably connected in the left guide rail 21, and the right guide plate 30 is slidably connected in the right guide rail 33. To prevent the guide plates 20 and 30 from detaching, a left guide plate pressure plate 19 can be provided on both sides of the left guide plate 20 above the left guide rail 21 to prevent the left guide plate 20 from detaching, and a right guide plate pressure plate 29 and 31 can be provided on both sides of the right guide plate 30 above the right guide rail 33 to prevent the right guide plate 30 from detaching. To protect the internal structure and prevent dust from entering, protective covers 15 and 8 can be provided on the top of the left guide rail 21 and the right guide rail 33. The figure also shows a left guide plate bracket 18 and a right guide plate bracket 32.

[0063] To further reduce the workload of manual plate loading and improve processing efficiency, a bottom plate storage slot 16 can be provided on the fixed base 500 (i.e., the upper fixed plate 7) on the side of the line connecting the left guide plate 20 and the right guide plate 30 (the front side in the embodiment shown in the figure). Specifically, the bottom plate storage slot 16 can store 10-20 bottom plates 200. The bottom plate storage slot 16 has a bottom plate outlet at its lower end. On the side of the bottom plate storage slot 16 away from the bottom plate receiving slot 300, the fixed base 500 has a guide tongue 24 that can move back and forth to push the bottom bottom plate 200 in the bottom plate storage slot 16 into the bottom plate receiving slot 300. The fixed base 500 is provided with a third driving device for driving the guide tongue 24 to move back and forth.

[0064] At this time, the aforementioned step 1 is further as follows: the bottom plate 200 is placed in the bottom plate storage slot 16, and the guide tongue 24 is moved by the third driving device to push the bottom plate 200 located at the bottom layer in the bottom plate storage slot 16 into the bottom plate receiving slot 300.

[0065] In this step, the manual switch 12 can be pressed for the first time. After the second drive device drives the left guide plate 20 and the right guide plate 30 to close, the third drive device drives the guide tongue 24 to move forward so as to push the bottom plate 200 located in the bottom plate storage slot 16 into the bottom plate receiving slot 300.

[0066] To facilitate positioning and accommodating the base plate 200, the base plate receiving groove 300 can be a C-shaped receiving groove as shown in the figure, which is formed by a pair of side baffles 301 arranged opposite to each other on both sides of the base plate receiving groove 300 and a far end baffle 6 located on the side away from the base plate storage groove 16.

[0067] To facilitate the storage of the base plate 200, the base plate storage slot 16 is preferably composed of a pair of U-shaped uprights 161 arranged opposite each other. To facilitate the guidance and positioning of the guide tongue 24, a guide tongue guide rail 26, 28 can be provided on the side of the base plate storage slot 16 away from the base plate receiving slot 300 on the fixing base 500 (i.e., the upper fixing plate 7), and the guide tongue 24 is slidably connected within the guide tongue guide rail 26, 28. To prevent the guide tongue 24 from detaching, guide tongue pressure plates 23, 25 can be provided on both sides of the guide tongue 24 above the guide tongue guide rails 26, 28 to prevent the guide tongue 24 from detaching. To protect the internal structure and prevent dust from entering, a protective cover 17 can be provided above the guide tongue 24; a guide tongue bracket 27 is also shown in the figure. For ease of implementation, the third driving device in this invention is preferably a guide tongue cylinder 35.

[0070] The side of the housing 10 may be provided with a power socket 43, an air pipe connector 40 for supplying air to each cylinder, and a foot switch socket 11 for connecting a foot switch to control the pressing device, the first drive device, the second drive device and the third drive device, so as to facilitate turning on the foot switch.

[0071] The housing 10 may contain a microcontroller control unit 41, a solenoid valve group 39, and a switching power supply 42 to ensure normal operation of the machine.
