[0002] US Patent No. 2018 / 049661A1 discloses a headband electrode carrier system, which is a headband for quickly and easily acquiring electroencephalogram (EEG) signal data, such as EEG data on epilepsy and epileptiform activity. The product assembly process includes welding, dispensing, UV curing, powder coating, and laser marking. During the critical dispensing and UV curing processes, turnover fixtures are needed for rapid positioning and workstation switching to ensure production efficiency and positioning accuracy. Typically, the assembly process of a headband electrode carrier system requires two different fixtures, meaning a fixture change is necessary midway through assembly. Using two fixtures is not only costly but also reduces assembly efficiency due to fixture changes. Utility Model Content

[0003] In view of the technical problem that the assembly of the headband electrode carrier system in the prior art requires two jigs, which is not only costly, but also results in low assembly efficiency due to the jig replacement steps, the purpose of this utility model is to provide a two-in-one rotating jig for the installation of the headband electrode carrier system.

[0004] The two-in-one rotary fixture for installing the headband electrode carrier system of this utility model is equipped with:

[0005] Several first positioning holes arranged side by side for fixing electrode assemblies;

[0006] Several second positioning holes arranged side by side for fixing electrode assemblies, the bottom of the second positioning holes being light-transmitting;

[0007] A plurality of hollow slots arranged side by side and a plurality of light-transmitting plates respectively installed in the hollow slots, wherein the second positioning holes are respectively provided on the light-transmitting plates.

[0008] Preferably, the bottom of the first positioning hole and the bottom of the second positioning hole are hole bottoms that are consistent with the bottom shape of the corresponding electrode assembly, and more preferably contour hole bottoms.

[0009] Preferably, the two-in-one rotary fixture has, from the outside to the middle, two end first positioning holes, two proximal end first positioning holes and six middle first positioning holes, as well as two end second positioning holes, two proximal end second positioning holes and six middle second positioning holes.

[0010] Among them, the bottom of the two end first positioning holes and the bottom of the two end second positioning holes are circular flat bottoms, which are consistent with the bottom shape of the electrode assembly fixed at the upper end of the two-in-one rotary fixture; and the circular flat bottoms of the two end second positioning holes have positioning pins that are consistent with the bottom groove shape of the bottom of the end electrode assembly.

[0011] The bottom of the two proximal first positioning holes and the bottom of the two proximal second positioning holes have proximal waist-shaped positioning grooves with the same shape. The proximal waist-shaped positioning grooves are consistent with the shape of the waist-shaped fork teeth at the bottom of the proximal electrode assembly fixed on the two-in-one rotary fixture.

[0012] The bottom of the six central first positioning holes and the bottom of the six central second positioning holes have a central waist-shaped positioning groove with the same shape. The central waist-shaped positioning groove has the same shape as the waist-shaped fork tooth at the bottom of the central electrode assembly fixed on the two-in-one rotary fixture.

[0013] Preferably, the light-transmitting plate is detachably disposed in the hollow groove of the two-in-one rotating fixture by screws.

[0014] Preferably, the light-transmitting plate is a transparent acrylic plate.

[0030] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0031] like Figures 1-4 As shown, the two-in-one rotary fixture 10 for installing the headband-type electrode carrier system of this utility model includes a plurality of first positioning holes 11 arranged side by side for fixing the electrode assembly 20 and a plurality of second positioning holes 12 arranged side by side for fixing the electrode assembly 20, wherein, as Figure 2 As shown, the bottom of the second positioning hole 12 is light-transmitting.

[0032] Continue as Figure 3 and Figure 4 As shown, the two-in-one rotating fixture 10 has several hollowed-out grooves 101 arranged side by side. Several light-transmitting plates 102 are installed within each of the hollowed-out grooves 101. Second positioning holes 12 are respectively provided on these light-transmitting plates 102, so that when the bottom of the two-in-one rotating fixture 10 is irradiated with UV light, the UV light can pass through the light-transmitting plates 102 at the second positioning holes 12, fully curing the UV adhesive within the second positioning holes 12 to firmly bond the knobs attached to the electrode assembly. In a further example, the light-transmitting plates 102 are detachably mounted within the hollowed-out grooves 101 of the two-in-one rotating fixture 10 using screws. Of course, other mounting methods are also possible, such as bonding, etc., which are not limited here. Furthermore, the light-transmitting plates are transparent acrylic sheets.

[0033] Continue as Figure 1 and Figure 4 As shown, the bottom of the first positioning hole 11 and the bottom of the second positioning hole 12 are contoured holes with the same shape as the bottom of the corresponding electrode assembly 20, which can perfectly lock the electrode assembly 20 in the first positioning hole 11 and the second positioning hole 12, preventing the electrode assembly 20 from moving during operation.

[0034] In this example, electrode assembly 20 comes in three different sizes, each with a different bottom shape. The first type is as follows: Figure 5 and Figure 6 The end electrode assembly 21 shown has a flat, round bottom and a bottom groove 211 on its flat, round bottom. The second type is as follows... Figure 7 and Figure 8 The bottom shown is the proximal electrode assembly 22 with a large waist-shaped fork tooth 221. The third type is as follows: Figure 9 and Figure 10 The bottom part is the middle electrode assembly 23 with small waist-shaped fork teeth 231. Of course, other specifications of electrode assemblies can also be used, which are not limited here.

[0035] In this example, continue as follows Figure 1As shown, the two-in-one rotary fixture 10 has, from the outside to the middle, two end first positioning holes 111, two proximal end first positioning holes 112, and six middle first positioning holes 113, as well as corresponding two end second positioning holes 121, two proximal end second positioning holes 122, and six middle second positioning holes 123. The bottoms of the two end first positioning holes 111 and the two end second positioning holes 121 have the same shape as the bottom of the end electrode assembly 21 fixed to the upper end of the two-in-one rotary fixture 10, both being circular and flat. Furthermore, as... Figure 11 As shown, positioning pins 1211 are provided on the bottom of the circular flat holes 121 at both ends, matching the bottom grooves 211 on the flat circular bottom of the end electrode assembly 21. These pins perfectly engage and fix the electrode assembly 21 on the bottom of the circular flat holes, preventing rotation. Square perforations 1212 are also provided on the bottom of the two end second positioning holes 121 to increase the amount of UV light transmitted through the bottom of the two end second positioning holes 121, thus improving curing. Of course, the shape of the perforations on the bottom of the two end second positioning holes 121 is not fixed, as long as it increases light transmission. Since the two end second positioning holes 121 themselves are light-transmitting holes, square perforations are not required. The bottoms of the two proximal first positioning holes 112 and the two proximal second positioning holes 122 have proximal waist-shaped positioning grooves of the same shape. These proximal waist-shaped positioning grooves are identical in shape to the large waist-shaped fork teeth 221 at the bottom of the proximal electrode assembly 22 fixed on the proximal end of the two-in-one rotary fixture 10. The bottoms of the six central first positioning holes 113 and the six central second positioning holes 123 have central waist-shaped positioning grooves of the same shape. These central waist-shaped positioning grooves are identical in shape to the small waist-shaped fork teeth 231 at the bottom of the central electrode assembly 23 fixed on the central part of the two-in-one rotary fixture 10.

[0036] Continue as Figure 1 As shown, the two-in-one rotating fixture 10 is also equipped with a wire harness fixing seat 31 for winding the wire harness. A long horizontal bar 32 is provided on the top of the wire harness fixing seat 31 to prevent the wire harness wound on the wire harness fixing seat 31 from falling off. Wire clamping seats 33 are respectively provided on the edge of the first positioning hole 11 for fixing the wire harness. After one end of the wire harness is wound around the wire harness fixing seat 31, the wire at the other end of the wire harness is clamped onto the wire clamping seat 33, which facilitates the application of adhesive to the electrode assembly 20 fixed in the first positioning hole 11 for curing, preventing the wire harness from moving during operation. Furthermore, both ends of the wire clamping seat 33 are fixed to the two-in-one rotating fixture 10 by screws.

[0037] like Figure 12As shown, a strap seat 41 is provided on both outer sides of the second positioning hole 12 arranged side by side on the two-in-one rotating fixture 10. The two ends of the fabric tape 40 are secured to the strap seat 41, thereby fixing the fabric tape 40 above the second positioning hole 12 of the two-in-one rotating fixture 10. Several retaining rings 42 for securing the electrode assembly 20 are provided along the length of the fabric tape 40, enabling the electrode assemblies to be connected in series. When the fabric tape 40 is fixed above the second positioning hole 12, the retaining rings 42 on the fabric tape 40 can sequentially correspond to the positions above the second positioning hole 12, thereby fixing the electrode assembly 20 within the second positioning hole 12. In this example, continuing as... Figure 1 As shown, the strap seats 41 at both ends of the two-in-one rotating fixture 10 have different shapes. One end of the strap seat 41 is a parallel convex strip retainer 411, and the other end is a U-shaped hole retainer 412. The fixing seats at both ends of the fabric tape 40 are also different. One end has two parallel retaining holes that fit inside the parallel convex strip retainer 411, and the other end has a convex strip that can be fitted into the U-shaped hole retainer 412, thereby fixing the fabric tape 40 onto the two-in-one rotating fixture 10. Of course, the strap seats and the fixing seats at both ends of the fabric tape can also be other shapes, as long as they can serve the purpose of fixing the two ends of the fabric tape through the strap seats. There is no limitation here. Furthermore, the fabric tape 40 is a medium-sized double-layer fabric tape.

[0038] Furthermore, continuing as Figure 1 As shown, handles 50 are provided at both ends of the two-in-one rotating fixture 10. Furthermore, the handles 50 are screwed onto the two-in-one rotating fixture 10, making it convenient for the operator to hold the handles and move the two-in-one rotating fixture 10.

[0039] Continue as Figure 12 As shown, after fixing the electrode assembly 20 onto the first positioning hole 11, the two-in-one rotary fixture 10 is placed on the first tooling to apply adhesive to the electrode assembly wire harness for the first time. Then, UV curing is performed directly on top of the adhesive-coated electrode assembly 20 to fix the electrode assembly 20 to the wires of the wire harness. Figure 13 As shown, the fixture is removed from the first tooling and placed on the worktable, and the electrode assembly 20, after the first application of adhesive and curing, is inserted into the retaining ring 42 already placed in the second positioning hole 12. Then, the two-in-one rotating fixture 10 is moved to the second tooling, and a second application of adhesive is performed around the periphery of the electrode assembly 20. Figure 14As shown, the fixture is then removed from the second tooling and placed on the worktable, and the knob 60 is placed on the electrode assembly 20 after the adhesive has been applied. The two-in-one rotary fixture 10 is then directly moved to the third tooling, and UV light is shone from the bottom of the two-in-one rotary fixture 10 onto the second application of UV adhesive in the bottom of the light-transmitting hole of the second positioning hole 12. The cured UV adhesive bonds the electrode assembly 20 to the knob 60. In other words, in this invention, when performing the second UV curing of the electrode assembly knob, it is only necessary to directly move the two-in-one rotary fixture 10 to the third tooling, without needing to remove the electrode assembly after the second application of adhesive, replace it with another fixture, and then move it to the third tooling, greatly improving the assembly efficiency of the headband electrode carrier system.

[0040] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
