Description

Technical Field

[0001] The utility model belongs to the technical field of relay coil winding, in particular to an improved device for a relay winding table which first inserts an iron core and then performs coil winding. Background Art

[0002] The existing relay winding mechanism is a production method of winding with an empty winding table first. Figures 1 to 3 As shown, the relay reel 10 of the existing relay reel winding mechanism has a winding machine shaft mounting center hole 11. The relay reel 10 is directly fixed to the winding machine shaft 20 through the winding machine shaft mounting center hole 11 for winding. This production method of winding with an empty reel requires that the winding machine shaft mounting center hole 11 be reserved for winding. This will cause certain limitations on the thickness of the relay reel, resulting in limitations on the width of the finished relay. This imposes certain installation space requirements on the finished relay when used by customers, and is particularly unable to meet the requirements of special small installation spaces.

[0003] In summary, the current application structure of the empty-coil winding production method presents a significant bottleneck in improving the application of finished relay products. To overcome these technical difficulties, it is urgent to develop a solution with wider application scope and greater market competitiveness. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a winding mechanism for a pre-installed iron core type relay reel. The relay reel winding mechanism can achieve the extreme reduction of the width of the finished relay, thereby reducing the space requirements for customers to install the relay, greatly enhancing the installation advantage over similar type relays, making it easier to gain customer recognition and improving the product's market competitiveness.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A pre-installed iron core type relay winding table winding mechanism is characterized by comprising a winding table fixing shaft, a relay winding table, an iron core, a magnet and a winding machine main shaft fixing fixture; wherein,

[0007] The relay winding table has an auxiliary shaft mounting portion that is nested with the auxiliary shaft fixed to the winding table, and a main shaft mounting portion that is nested with the main shaft fixing fixture of the winding machine;

[0008] The iron core is tightly fitted and fixed in the iron core mounting hollow hole groove provided on the relay winding table; and the left and right sides of the iron core have exposed surfaces in the hollow part of the iron core mounting hollow hole groove; the rear end of the iron core is magnetically attracted to the winding table fixed attached shaft, and the front end of the iron core is magnetically attracted to the winding machine main shaft fixing fixture to connect the winding table fixed attached shaft and the winding machine main shaft fixing fixture.

[0009] The winding machine main shaft fixing device has a winding table front end mounting portion that is nested with the main shaft mounting portion of the relay winding table;

[0010] The magnet is tightly fixed in the magnet mounting hole provided in the winding machine main shaft fixing fixture, and the magnet is magnetically matched with the front end of the iron core;

[0011] The reel fixing shaft is provided with a reel rear end mounting portion which is nested with the shaft mounting portion of the relay reel, and the rear end of the iron core is magnetically matched with the reel rear end mounting portion.

[0012] As described above, in a pre-installed iron core type relay winding table winding mechanism, the rear end portion of the iron core is arranged corresponding to the position of the auxiliary shaft mounting portion of the relay winding table, and the front end portion of the iron core protrudes from the iron core mounting hollow hole groove to be nested on the rear end mounting portion of the winding table where the auxiliary shaft is fixed.

[0013] As described above, in a pre-installed iron core type relay winding table winding mechanism, the front end portion of the iron core is arranged corresponding to the position of the main shaft mounting portion of the relay winding table, and the front end portion of the iron core protrudes from the iron core mounting hollow hole groove to be nested in the front end mounting portion of the winding table of the winding machine main shaft fixing fixture.

[0014] In the aforementioned pre-installed core-type relay winding table winding mechanism, the magnet is arranged at a position corresponding to the front end mounting portion of the winding table of the winding machine main shaft fixing fixture.

[0015] The technical solution provided above has the following beneficial effects:

[0016] First, the present invention's pre-installed core-type relay winding mechanism pre-installs the core on the relay winding table before winding. A magnet is then installed in the winding machine's spindle fixture, which tightly attracts the core. This not only ensures a stable connection between the relay winding table and the winding machine's spindle fixture, but also allows the spindle fixture to attract the relay winding table for winding. This pre-installed core-type relay winding table structure minimizes the thickness of the relay winding table, minimizing the size of the finished relay.

[0017] Secondly, the winding mechanism of the iron core type relay reel of the present invention is provided with a reel fixing shaft which firmly connects the relay reel and the iron core during the winding operation. This not only provides stable support for the relay reel during the winding process, but also prevents the relay reel from being damaged by shaking.

[0018] In summary, the core purpose of the present invention is to provide an efficient, reliable and easy-to-operate relay winding mechanism to comprehensively solve the problems existing in the prior art and promote technological progress and development of the relay manufacturing industry.

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] In the claims, the specification, and the drawings of the present application, terms such as "first", "second", and "third" are used merely to distinguish one object or implementation from another, without necessarily implying a particular order or sequence.

[0036] The present application will be described in detail below with reference to the drawings. Figures 4 to 11 As shown in the drawings, the present application is a kind of first core type relay reel winding mechanism, including reel fixed auxiliary shaft 100, relay reel 200, iron core 300, magnet 400 and winding machine main shaft fixing jig 500.Winding work, the relay reel 200 is first inserted with iron core 300, then the relay reel 200 with the iron core 300 is connected together with the reel fixed auxiliary shaft 100 and winding machine main shaft fixing jig 500.Compared with the prior art, the improved relay reel winding mechanism is suitable for the winding of the relay reel 200 with the iron core 300, can minimize the thickness of the relay reel 200, realize the minimization of the appearance size of the relay reel 200, and improve the product competitiveness.

[0037] Specifically, the rear end of the relay reel 200 is an auxiliary shaft mounting portion 210, which is used for cooperating with the reel fixed auxiliary shaft 100 to be nested, and the front end of the relay reel 200 is a main shaft mounting portion 220, which is used for cooperating with the winding machine main shaft fixing jig 500 to be nested.

[0038] The relay reel 200 of the present invention has a core mounting hollow slot 230, and the core 300 is tightly fitted and fixed in the core mounting hollow slot 230. Figure 8 As shown, the left and right sides of the iron core 300 of the present invention have exposed surfaces 330 in the hollow of the iron core mounting hollow slot 230, so that the copper wire can be directly wound on the iron core 300 when the relay winding platform 200 of the present invention is working.

[0039] The relay winding table 200 of the present invention is magnetically attracted to the winding table fixed shaft 100 through the rear end portion 310 of the iron core 300, and is magnetically attracted to the winding machine main shaft fixing fixture 500 through the front end portion 320 of the iron core 300, so as to connect the winding table fixed shaft 100 and the winding machine main shaft fixing fixture 500.

[0040] The rear end portion 310 of the iron core 300 of the present invention is arranged to correspond to the position of the auxiliary shaft mounting portion 210 of the relay reel 200, and the front end portion 320 of the iron core 300 protrudes from the iron core mounting hollow hole 230, so that the iron core 300 is not only magnetically attracted to the reel rear end mounting portion 110 of the reel fixed auxiliary shaft 100, but can also be nested on the reel rear end mounting portion 110 of the reel fixed auxiliary shaft 100, together with the auxiliary shaft mounting portion 210 of the relay reel 200, further stabilize the connection between the relay reel 200 and the reel fixed auxiliary shaft 100.

[0041] The front end portion 320 of the iron core 300 of the present invention is arranged to correspond to the position of the spindle mounting portion 220 of the relay winding table 200, and the front end portion 320 of the iron core 300 protrudes from the iron core mounting hollow hole groove 230, so that the iron core 300 is not only magnetically attracted to the magnet 400 fixed in the winding machine spindle fixing fixture 500, but can also be nested in the winding table front end mounting portion 510 of the winding machine spindle fixing fixture 500, together with the spindle mounting portion 220 of the relay winding table 200, further stabilizing the connection between the relay winding table 200 and the winding machine spindle fixing fixture 500.

[0042] The rear end of the winding machine spindle fixing fixture 500 of the present invention is a winding table front end mounting portion 510, and the winding table front end mounting portion 510 is used to cooperate and nest with the spindle mounting portion 220 of the relay winding table 200. The winding machine spindle fixing fixture 500 of the present invention is provided with a magnet mounting hole 520, and the magnet 400 is tightly fixed in the magnet mounting hole 520, and the magnet 400 is arranged at a position corresponding to the winding table front end mounting portion 510. The magnet 400 is used to tightly attract the iron core 300, not only enabling the winding machine spindle fixing fixture 500 to adsorb the relay winding table 200 for winding work, but also further stabilizing the connection between the relay winding table 200 and the winding machine spindle fixing fixture 500.

[0043] The winding platform fixing attachment shaft 100 of the present invention includes an attachment shaft body, the front end of which serves as a winding platform rear end mounting portion 110. This rear end mounting portion 110 is not only designed to nest with the attachment shaft mounting portion 210 of the relay winding platform 200, but also magnetically attracts the iron core 300 fixed within the relay winding platform 200. This provides stable support for the relay winding platform 200 during the winding process, preventing the relay winding platform 200 from shaking and causing various damage to the relay winding platform 200.

[0044] Specifically, when the winding machine is working, the iron core 300 is first inserted into and fixed in the iron core mounting hollow hole 230 of the relay winding table 200, and the relay winding table 200 with the inserted iron core 300 is sent to the winding machine main shaft fixing fixture 500 equipped with a magnet 400 through the winding machine's conveying mechanism for adsorption. After the relay winding table 200 and the winding machine main shaft fixing fixture 500 are nested and fixed, the winding machine's driving mechanism drives the winding table fixing auxiliary shaft 100 to move forward and adsorb the iron core 300 in the relay winding table 200, and at the same time completes the nesting and fixation of the winding table fixing auxiliary shaft 100 and the relay winding table 200; then the relay winding table 200 performs the winding action again.

[0045] The aforementioned pre-installed iron core relay winding platform structure reduces the width L of the upper and lower slot walls 231 and 232 of the core mounting hollow slot 230 of the relay winding platform 200, minimizing the overall thickness of the relay winding platform 200 while also leaving space for the copper wire wound around the relay winding platform 200. The copper wire can be wound directly onto the core 300 within the hollow portion of the core mounting hollow slot 230, specifically onto the exposed surfaces 330 on the left and right sides of the core 300, minimizing the size of the finished relay. However, the prior art approach of pre-installing an empty winding platform requires the winding platform to support the copper wire, increasing the thickness of the winding platform.

[0046] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention is applicable to various other combinations, modifications, and environments and is capable of modification within the scope of the present invention as described herein, through the teachings above, or through techniques or knowledge in the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
