[0025] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, this application proposes an automated pressing device for foundation boxes, which includes a gripping mechanism 1 and a pressing mechanism 2. The gripping mechanism 1 includes an inner tray loading robotic arm 11 and an inner cover loading robotic arm 12 arranged at intervals. The movable end of the inner tray loading robotic arm 11 integrates an inner tray gripping module 13 and a finished product unloading module 14, which are used to grip and load the inner tray and unload the pressed finished product, respectively. The movable end of the inner cover loading robotic arm 12 is equipped with an inner cover gripping module 15 for gripping and loading the inner cover. The pressing mechanism 2 includes a pressing machine platform 21, a pressing fixture 22 that can move horizontally on the pressing machine platform 21, a horizontal movement drive module 23 that drives the pressing fixture 22 to move horizontally, and a pressing actuator 24 that is set above the moving path of the pressing fixture 22. The pressing actuator 24 is used to perform pressing action on the inner plate and the inner cover. This realizes the full automation of the entire process of inner plate feeding, inner cover feeding, pressing, and finished product unloading, reduces manual intervention, and achieves high efficiency, high precision and high yield in the pressing process of inner plate and inner cover.

[0027] like Figure 6 As shown, the upper surface of the loading device 22 is provided with a plurality of equally spaced contour-imitating slots 221. The slots 221 are contour-imitatingly set with the inner plate and the inner cover, providing a precise positioning basis for the loading of the inner plate and the inner cover.

[0028] like Figure 1-2 As shown, the inner disc gripping module 13 includes a first mounting frame 131, on which a plurality of first vacuum suction units are arranged in a matrix for picking up the inner disc from the inner disc injection molding machine. In this embodiment, the first vacuum suction units are arranged at equal intervals along a first direction, and their intervals are equal to the discharge interval of the inner disc on the inner disc injection molding machine and the interval of the receiving groove on the pressure loading fixture, which enables the inner disc gripping module to directly pick up and transfer the inner disc from the inner disc injection molding machine to the pressure loading fixture.

[0029] The first vacuum suction device 132 includes a first positioning cover 1321 that conforms to the groove on the surface of the inner disk. A first vacuum suction cup 1322 is located at the center of the first positioning cover 1321. The first vacuum suction cup 1322 is elastically connected to the first mounting bracket 131 by a first spring. When the first vacuum suction cup 1322 is not subjected to external force (the spring is not compressed), the suction end of the first vacuum suction cup 1322 protrudes from the end of the first positioning cover 1321. This ensures that when the first vacuum suction device 132 suctions the inner disk, the first vacuum suction cup 1322 first abuts against the surface of the inner disk, the spring is compressed, and then the first positioning cover 1321 is pressed into the groove on the surface of the inner disk. The first vacuum suction cup 1322 suctions through negative pressure vacuum, which can effectively prevent the inner disk from shifting, rotating, or falling off during the gripping process.

[0030] like Figure 1 , 3 As shown in Figure 4, the finished product unloading module 14 includes a second mounting frame 141. The second mounting frame 141 is provided with multiple finished product gripping units 142 arranged along a first direction. Each finished product gripping unit 142 includes a mounting plate 1421 and several pneumatic grippers 1422 evenly spaced along a second direction on the mounting plate 1421. The pneumatic grippers 1422 are used to grip products that have been press-fitted into the receiving groove 221. In this specific embodiment, the pneumatic grippers 1422 can be rotary pneumatic grippers. The rotary pneumatic grippers grip the finished product from the receiving groove 221 and transfer it to an external material tray. The rotary pneumatic grippers can drive the product to rotate, so as to adjust the unloading angle of the finished product according to the angle of the receiving groove in the material tray.

[0031] like Figure 1 , 3 As shown in Figure 4, the finished product unloading module 14 also includes a first spacing adjustment mechanism, which includes a first telescopic cylinder 1431 and multiple sets of first connecting rods 1432. The push rod of the first telescopic cylinder 1431 is connected to the mounting plate 1421 at the beginning or end. One end of each first connecting rod 1432 is fixed to a mounting plate, and the other end extends to an adjacent mounting plate and is provided with a first guide groove 1433 extending in a first direction. The adjacent mounting plate is provided with a first guide post 1434 embedded in the first guide groove 1433. The first spacing adjustment mechanism is driven by the first telescopic cylinder 1431, and through the mutual cooperation of the first connecting rods 1432, the first guide grooves 1433 and the first guide posts 1434, it can realize the synchronous and equidistant opening and closing of multiple finished product gripping units. When the first telescopic cylinder 1431 is in the retracted state and the extended state respectively, the first guide post 1434 is located at both ends of the first guide groove 1433. The two sets of spacing between the finished product gripping units are respectively matched with the spacing between the receiving grooves 221 on the pressure loading device 22 and the spacing between the receiving grooves on the external material tray, which effectively improves the applicability of the equipment and makes the switching process simple and convenient.

[0032] The inner plate gripping module 13 and the finished product unloading module 14 are both integrated into the inner plate loading robotic arm 11, which enables the robotic arm to complete the two actions of inner plate placement and finished product removal in one stroke, further improving production efficiency.

[0033] like Figure 1 and 5 As shown, the inner cover gripping module 15 includes a third mounting bracket 151, on which a first inner cover gripping unit 152 is fixed. A second inner cover gripping unit 153 is provided on the adjacent side of the first inner cover gripping unit 152 along the first direction. The second inner cover gripping unit 153 is slidably disposed on the third mounting bracket 151, and the second inner cover gripping unit 153 is connected to a second spacing adjustment mechanism. The second spacing adjustment mechanism drives the second inner cover gripping unit 153 to slide along the first direction.

[0034] like Figure 1 and 5 As shown, the first inner cover gripping unit 152 and the second inner cover gripping unit 153 have the same structure, both including a connecting plate 1521, with a plurality of second vacuum suction units arranged in a matrix along the connecting plate 1521. In this embodiment, the second vacuum suction unit includes a second positioning cover 1522 that is conformally arranged to the groove on the surface of the inner cover. A second vacuum suction cup 1523 is provided at the center of the second positioning cover 1522, and the second vacuum suction cup 1523 is elastically connected to the connecting plate 1521 by a second spring. The second positioning cover 1522 and the second vacuum suction cup 1523 cooperate with each other to effectively prevent the inner cover from shifting, rotating, or falling off during the gripping process.

[0035] Preferably, the side of the second positioning cover 1522 is provided with a positioning guide block 1524 for calibrating the adsorption angle of the inner cover to ensure that the orientation is accurate when placed on the pressure loading device.

[0036] like Figure 5 As shown, the second spacing adjustment mechanism includes a second telescopic cylinder 1541 and a second connecting rod 1542. The push rod of the second telescopic cylinder 1541 is connected to the second inner cover gripping unit 153. One end of the second connecting rod 1542 is fixed to the first inner cover gripping unit 152 or the second inner cover gripping unit 153, and the other end is provided with a second guide groove 1543 extending in the first direction. The other inner cover gripping unit is correspondingly provided with a second guide post 1544 that passes through the second guide groove 1543.

[0037] like Figure 1 and 6As shown, the pressing actuator 24 includes a support frame 241 mounted on the pressing machine base 21, a pressing cylinder 242 mounted on the support frame 241, and a product-conforming pressing head 243 connected to the output end of the pressing cylinder 242. The pressing cylinder 242 drives the product-conforming pressing head 243 to perform pressing action on the inner disc and inner cover within the receiving groove 221. The shape of the pressing head matches the product, and in conjunction with the conforming receiving groove 221 on the pressing fixture 22, it ensures that the pressing force is applied evenly to the correct position, improving pressing quality and consistency, and increasing product yield.

[0038] The lateral movement drive module 23 drives the pressing fixture 22 to move laterally, allowing the pressing fixture 22 to move out from under the pressing actuator 24 to receive the inner disc and inner cover. Then, the pressing fixture 22 is moved to below the pressing head of the pressing actuator 24 to press the inner disc and inner cover together. In a specific embodiment, the lateral movement drive module 23 includes components such as a motor, a lead screw, and a slide rail that cooperate with each other.

[0039] Working principle:

[0040] The inner plate loading robotic arm 11 moves above the inner plate injection molding machine, the inner plate gripping module 13 descends, the first vacuum suction cup 1322 contacts the inner plate surface first, the first spring is compressed, the first positioning cover 1321 is embedded in the inner plate groove, the vacuum adsorption is started, and the inner plate is accurately gripped. The robotic arm moves above the pressure loading fixture 22 and accurately places the inner plate into the simulated shape positioning slot 221.

[0041] The inner cover loading robotic arm 12 moves above the inner cover injection molding machine, the inner cover gripping module 15 descends, the second vacuum suction cup 1523 contacts the inner cover surface first, the second spring is compressed, and the second positioning cover 1522 is embedded in the inner cover groove, vacuum adsorption is activated, and the inner cover is precisely gripped. If the spacing between the outer material trays is different from that of the receiving groove 221, the second spacing adjustment mechanism is activated, the second telescopic cylinder 1541 pushes the second inner cover gripping unit 153 to slide, that is, the second guide post 1544 moves along the second guide groove 1543 to complete the spacing adjustment of the two gripping units. The inner cover loading robotic arm 12 covers the inner cover on top of the positioned inner tray.

[0042] The transverse drive module 23 pushes the pressing fixture 22 to move horizontally to directly below the pressing actuator 24, and the pressing cylinder 242 drives the product contour pressing head 243 to press down, completing the pressing of the inner plate and the inner cover.

[0043] The loading device 22 returns to its initial position, and the inner tray loading robot arm 11 simultaneously moves the inner tray gripping module 13 and the finished product unloading module 14 above the loading device. The pneumatic gripper 1422 descends to grip the finished product that has been pressed in the receiving slot 221. If the spacing between the outer trays is not equal to the spacing between the receiving slots, the first spacing adjustment mechanism is activated, and the first telescopic cylinder 1431 pushes the mounting plate 1421. The first guide post 1434 slides along the first guide groove 1433, synchronously adjusting the spacing of all gripping units. The rotary pneumatic gripper 1422 rotates the finished product according to the tray angle and places it on the outer tray.

[0044] The inner plate grabbing module 13 operates simultaneously, placing a new batch of inner plates into the emptied receiving slot 221.
