Description

Technical Field

[0001] This utility model belongs to the field of automation equipment, and in particular relates to a press-fitting device for installing strip-shaped products such as sealing strips into a groove-shaped structure. Background Technology

[0002] In industrial production, many products require sealing properties to prevent the intrusion of liquids, gases, or dust. For this purpose, sealing strips are typically installed in grooves within the product casing to achieve a reliable seal.

[0003] In existing technologies, the pressing of sealing strips often employs roller-type sealing strip pressing devices, where the sealing strip is pressed into the groove by the rolling and squeezing action of the rollers. However, this traditional method has certain limitations: when the groove shape of the product housing is irregular (such as a bent or discontinuous structure) or the groove depth is inconsistent, the rollers cannot apply force evenly, leading to insufficient pressing of the sealing strip, localized deformation, or decreased sealing performance. Furthermore, roller pressing is less adaptable to complex curved surfaces or narrow spaces, easily causing damage to the sealing strip or improper installation, affecting the sealing quality and service life of the product.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] like Figure 1 , Figure 2 As shown, Embodiment 1 of this utility model discloses a sealing strip pressing device for pressing a sealing strip 400 into a groove with an irregular shape and depth. The sealing strip pressing device includes a pressing mechanism 100 and a supply mechanism 200. Both mechanisms are configured as guide rods, namely a first guide rod and a second guide rod. The pressing mechanism 100 and the supply mechanism 200 respectively have a first guide hole 110 and a second guide hole 210. A pressing member 300 is slidably disposed in the first guide hole 110, and the sealing strip 400 is slidably disposed in the second guide hole 210. The sealing strip 400 is rolled up and gradually unwound, and inserted into the groove by the supply mechanism 200. The pressing member 300 is in the shape of a slender rod, and the pressing member 300 is driven up and down by a driving mechanism 500 to press the sealing strip 400 into the groove. The pressing component 300, the pressing mechanism 100, and the supply mechanism 200 are all slender rods, which facilitates pressing the sealing strip 400 into grooves of irregular shape and depth, making the sealing strip pressing device more widely applicable.

[0026] The pressing mechanism 100 and the supply mechanism 200 are fixed at a set angle by a first fixing block 600, and the two guide rods are at a set angle. The smaller this set angle is, the easier it is to bring the two guide rods together and insert them into the groove.

[0027] The pressing mechanism 100 is mounted on a first mounting base 700 via a second fixing block 610, and the supply mechanism 200 is mounted on a second mounting base 800 via a third fixing block 620. The first mounting base 700 and the second mounting base 800 are fixed together, and the second mounting base 800 is connected to a six-axis robot (not shown in the figure), which controls the overall movement of the sealing strip pressing device.

[0028] A drive mechanism 500 is mounted on a first mounting base 700, and drives the pressing member 300 to reciprocate up and down. The drive mechanism 500 can be a hydraulic, pneumatic, or a crank-connecting rod, gear-rack, or similar mechanism. In this embodiment, the drive mechanism 500 uses a cam mechanism, including a rotary motor 510, a cam 520, and a connecting rod 530. The rotary motor 510 is mounted on the first mounting base 700, the cam 520 is connected to the rotating shaft of the rotary motor 510, and the connecting rod 530 is slidably mounted on the first mounting base 700 via a linear bearing. The lower end of the connecting rod 530 is connected to the pressing member 300, and the upper end of the connecting rod 530 is connected to the cam 520.

[0029] In this embodiment, the cam 520 is an eccentric wheel, and the axis of the rotary motor 510 is perpendicular to the connecting rod 530. An elastic element 540 is sleeved on the outer surface of the connecting rod 530, and a fixing element 550 is provided at the upper end of the connecting rod 530. One end of the elastic element 540 abuts against a linear bearing, and the other end abuts against the fixing element 550. The top end of the fixing element 550 abuts against the eccentric wheel. Under the action of the elastic element 540, the fixing element 550 can always abut against the eccentric wheel, and the connecting rod 530 reciprocates up and down under the action of the eccentric wheel.

[0030] In other embodiments, the elastic element may be omitted from the outer surface of the connecting rod 530. In this case, an annular groove is provided on the outer surface of the eccentric wheel, and the top end of the fixing member 550 is engaged in the annular groove.

[0031] The first mounting base 700 includes a fixed base plate 710 and a fixed vertical plate 720, a first support plate 730, a second support plate 740, and a linear bearing fixing plate 750, all perpendicular to the fixed base plate. The fixed vertical plate 720 and the second support plate 740 are disposed on the upper surface of the fixed base plate 710. The first support plate 730 and the linear bearing fixing plate 750 are disposed on the lower surface of the fixed base plate 710. A second fixing block 610 is mounted on the first support plate 730. Two second support plates 740 are provided. A rotary motor 510 is mounted on the fixed vertical plate 720, with its rotation shaft passing through the fixed vertical plate 720. A cam 520 is rotatably connected to the two second support plates 740 via bearings, and the rotation shaft of the rotary motor 510 is connected to the cam 520. A linear bearing is mounted on the linear bearing fixing plate 750, and a connecting rod 530 passes through the linear bearing fixing plate 750 and the fixed base plate 710, abutting against the cam 520.

[0032] The second mounting base 800 includes two upright plates 810, with three horizontal plates 820 arranged sequentially from top to bottom between them. The three horizontal plates 820 enhance the stability of the second mounting base 800. Each of the three horizontal plates 820 has a through hole for the sealing strip 400 to pass through. The first fixing block 600 is mounted on the lowermost horizontal plate 820 of the second mounting base 800 via a fourth fixing block 630. The arrangement of the second fixing block 610, the third fixing block 620, and the fourth fixing block 630 strengthens the stability of the pressing mechanism 100 and the supply mechanism 200 during installation. The first support plate 730 of the first mounting base 700 is connected to the upright plate 810 of the second mounting base 800, improving the stability of the first mounting base 700. The second mounting base 800 is connected to the six-axis robot via the uppermost horizontal plate 820.

[0033] like Figure 3 As shown, to reduce processing difficulty, the pressing mechanism 100 is a split design, comprising a first rod 120, a second rod 130, and a third rod 140 connected to each other. Each of the three rods has a first through hole 111, a second through hole 112, and a third through hole 113, which together form a first guide hole 110. The diameters of the first through holes 111 and 113 are slightly larger than the diameter of the pressing member 300, providing effective guidance. The first rod 120 is relatively short, facilitating the machining of the smaller diameter first through hole 111. The second rod 130 is a standard part, and the diameter of the second through hole 112 is not limited; it only needs to pass through the pressing member 300. The second rod 130 is threadedly connected to the first rod 120 and the second rod 130. The split pressing mechanism 100 and the second rod 130, which requires no machining, reduce processing costs and difficulty.

[0034] The third rod portion 140 is relatively long, facilitating insertion into grooves of varying depths. The outer surface of the third rod portion 140 is tapered, with its lower end being the smaller diameter end 141 and its upper end being the larger diameter end 142. This design allows the lower end of the pressing mechanism 100 to be thinner, making it easier to insert into narrower grooves.

[0035] Refer again Figure 2 As shown, a clearance opening 220 is provided at the supply end of the supply mechanism 200 and on the side near the pressing mechanism 100 to prevent the pressing member 300 from contacting the supply end of the supply mechanism 200 after it extends out.

[0036] like Figure 4As shown, in the second embodiment of this utility model, the rotation shaft of the rotary motor 510 is arranged parallel to the connecting rod 530. The outer surface of the cam 520 is provided with a continuous W-shaped groove 521. The connecting rod 530 is provided with a slider that cooperates with the W-shaped groove 521. The rotary motor 510 drives the cam 520 to rotate, and the cam 520 drives the connecting rod 530 to move up and down through the W-shaped groove 521 and the slider.
