[0027] Please see Figure 1-3 , Figure 1 This is a schematic diagram of a metal frame auxiliary material pressing device. Figure 2 This is a structural schematic diagram of a mid-frame fixing fixture. Figure 3 This is a structural diagram of a fixed base; the present invention provides an auxiliary material pressing device for a metal frame, including an electrical control component, a pressing component, a moving component and a housing, wherein the electrical control component, the pressing component and the moving component are all mounted on the housing.
[0028] The movable component includes a middle frame fixing fixture, a fixed base, and a base moving component; the fixed base is connected to the base moving component; a first positioning fixing component is provided on the middle frame fixing fixture, and a second positioning fixing component is provided on the fixed base to cooperate with the first positioning fixing component; the first positioning fixing component and the second positioning fixing component are detachably connected.
[0029] The electrical control component is connected to the pressing component, which can be moved to the position where the extrusion frame fixes the jig.
[0030] Specifically, the first positioning and fixing component can be a positioning pin hole, and the second positioning and fixing component can be a positioning pin; the first positioning and fixing component can be at least one first blind hole, and the second positioning and fixing component can be at least one second blind hole, with magnets of opposite polarity disposed in the first and second blind holes; the first positioning and fixing component can be a positioning pin hole and at least one first blind hole, and the second positioning and fixing component can be a positioning pin and at least one second blind hole. The diameter of the first and second blind holes can be, but is not limited to, 12 mm, and the depth can be, but is not limited to, 2 mm.
[0031] The magnet can be, but is not limited to, neodymium iron boron magnets (strong magnets, permanent magnets). Diameter 8-15mm, e.g., 12mm; thickness 1-3mm, e.g., 2mm. The attractive force of a single magnet is approximately 0.7KG-1.3KG, e.g., 1KG. Positioning pins, one large and one small, are distributed along a diagonal line of the four magnets on the fixed base. Two positioning pins are used for positioning to prevent fixture deflection; positioning accuracy is ±0.02mm.
[0032] The installation process of the fixing fixture can involve initially positioning the fixing fixture by using the locating pin holes on the fixing fixture and the locating pins on the fixing base, and then slightly adjusting the position of the fixing fixture or fixing base to ensure that the magnets are on the same axis. The fixing fixture and fixing base may also have threaded holes. After adjustment, the fixing fixture and fixing base are fixed with screws.
[0033] The number of first blind holes and second blind holes is unlimited. For example, four first blind holes can be set at the four corner points of the fixed fixture or at a position where the four corner points are moved inward by a preset distance, and four second blind holes can be set at the corresponding position of the fixed base.
[0034] The number of locating pin holes is unlimited. For example, there can be two pin holes, one large and one small (for foolproof purposes), with diameters of 8mm and 6mm respectively.
[0035] like Figure 4 As shown, Figure 4 This is an exploded view of an auxiliary material pressing device for a metal frame. The base moving component includes a second power component and a guide rail. The second power component is connected to a fixed base, and the fixed base is connected to the guide rail and can move along the guide rail. When the fixed base moves along the guide rail, it can drive the middle frame fixing fixture to move, and the metal frame can be placed in the middle frame fixing fixture.
[0036] The base moving component also includes at least one limiting part, which may be, but is not limited to, a limiting post or a limiting block. The limiting part may be fixed at a certain position on the guide rail, and when the fixed base moves along the guide rail to the limiting part, it will no longer move; the limiting part may be fixed at a certain position on the housing, and when the fixed base moves along the guide rail and contacts the limiting part, it will be blocked by the limiting part and will no longer move.
[0037] like Figure 2 As shown, the middle frame fixing fixture is provided with at least one stop block for fixing the metal middle frame.
[0038] like Figure 1 As shown, the pressing assembly includes a first power component, a pressure sensor, a top cover, a pressing fixture, and a top cover moving component.

The touchscreen is connected to the central control unit, and both the first power unit and the pressure sensor are connected to the central control unit. The connection method can be wireless or wired. The first power unit can be, but is not limited to, an electric cylinder.
[0040] The pressure sensor is fixed to the upper surface of the top cover and located at the contact point between the first power component and the top cover. The pressure sensor measures the pressure exerted by the first power component (electric cylinder) on the top cover. It can also be used as the pressure exerted by the pressing jig on the fixed jig when the pressing jig is in contact with the fixed jig. The pressure sensor feeds back the pressure to the central control electrical component, allowing it to adjust the pressure of the electric cylinder on the top cover based on the actual and target pressures. Force control and force feedback are possible to regulate the pressing pressure and reduce the risk of damaging the middle frame.
[0041] The lower surface of the top cover is in contact with the pressing fixture. The top cover moving part is fixed to the housing, and the top cover is also connected to the top cover moving part. The top cover moving part includes a fixed part and a moving part. The fixed part is fixed to the housing, and the moving part is connected to the top cover and drives the top cover to move along the fixed part, so that the top cover drives the pressing fixture to the position of the pressing fixture.
[0042] The fixed part can be a slide groove, and the moving part can be a slider. The slider moves in the slide groove, driving the top cover to move.
[0043] The fixed part includes a bearing, and the movable part includes an optical shaft. The optical shaft is sleeved on the bearing, which can be sleeved on the outer surface of the bearing or nested in the inner wall of the bearing.
[0044] This utility model has the following technical effects:
[0045] This device features positioning and fixing parts on a fixed fixture and a fixed base. These parts can be blind holes or positioning pins. Magnets of opposite polarity are placed in the blind holes. When changing the fixed fixture, the magnetic attraction and positioning pins are used to quickly position and fix the fixture. Through the synergy of rapid positioning via magnetic attraction / pin holes and electronic pressure feedback, efficient replacement of multiple fixture models and high-yield pressing are achieved.
[0046] This device is equipped with a central control unit, sensors, and an electric cylinder. This allows the central control unit to adjust the pressure of the electric cylinder on the pressing jig based on the actual and target pressure detected by the sensors. Force control and force feedback can be performed to regulate the pressing pressure and reduce the risk of damaging the middle frame.
[0047] This device, by setting guide rails and a second power component (cylinder), can move the fixed jig, making it easy for the fixed jig to cooperate with the external feeding port, thus realizing automated production without the need for manual loading and unloading.
[0048] Experimental data:
[0049] This invention uses existing technology and the pressing device of this invention to press the same auxiliary material, pressing 100 pieces of auxiliary material at a time. The existing technology achieves a pressing effect of 85 pieces, while the present invention achieves a pressing effect of 97 pieces, resulting in a 12% improvement in yield.
[0050] The experimental results of quick tool change are shown in Table 1. The operator was a machine adjustment technician with one month of work experience after on-the-job training, and the total time was 9.8 minutes.
