[0027] It should be noted that if the present invention involves directional indications, such as up, down, front, back, left, right, etc., then the directional indications are only used to explain the relative positional relationship between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly; if the present invention involves descriptions of "first", "second", etc., then the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0028] Depend on Figures 1 to 8 It can be seen that the attachment pressure-maintaining device includes a lifting drive mechanism and a carrier 11 fixedly connected to the output part of the lifting drive mechanism, and also includes a first pressure-maintaining component 20a and a second pressure-maintaining component 20b that are slidably installed on the lower side of the carrier 11 along the direction of approach / away, a third pressure-maintaining component 20c that is arranged at one end of the first pressure-maintaining component 20a and the second pressure-maintaining component 20b and is slidably installed on the lower side of the carrier 11 along the sliding direction of the first pressure-maintaining component 20a and the second pressure-maintaining component 20b, and a sliding drive mechanism for driving the first pressure-maintaining component 20a, the second pressure-maintaining component 20b and the third pressure-maintaining component 20c to slide, the first pressure-maintaining component 20a, the second pressure-maintaining component 20b and the third pressure-maintaining component 20c respectively include a plate-shaped pressure head 21, and a positioning structure and a plurality of suction holes are provided on the outer side of the pressure head 21; usually, two positioning structures are arranged at intervals, and the positioning structure is a positioning pin 40. Of course, the positioning structure is a positioning groove, and a plurality of suction holes are provided on the bottom surface of the positioning groove.

[0029] When attaching the lining parts, the lining parts are placed on the outside of the first pressure-maintaining component 20a, the second pressure-maintaining component 20b, and the third pressure-maintaining component 20c respectively. The lining parts are positioned by the positioning structure and fixed by adsorption through multiple suction holes. The first pressure-maintaining component 20a, the second pressure-maintaining component 20b, and the third pressure-maintaining component 20c are driven by the lifting drive mechanism to fall into the interior of the cavity surrounded by the product, and then the first pressure-maintaining component 20a, the second pressure-maintaining component 20b, and the third pressure-maintaining component 20c are driven to slide by the sliding drive mechanism. The lining parts are respectively attached to the inner wall of the corresponding side and pressure-maintained by the first pressure-maintaining component 20a, the second pressure-maintaining component 20b, and the third pressure-maintaining component 20c. The attaching and pressure-maintaining device of the embodiment of the present invention can attach the lining parts to the inner wall in three directions at the same time, and can maintain pressure after the lining parts are attached, which solves the problems of the existing manual attachment of the lining parts, which is difficult and inefficient.

[0030] In an embodiment of the present invention, in order to facilitate pressure maintenance and avoid hard collisions with the product during attachment and pressure maintenance, the first pressure-maintaining component 20a, the second pressure-maintaining component 20b, and the third pressure-maintaining component 20c further include a push-pull member 22 spaced apart from the pressure head 21, an elastic telescopic member 24 in a compressed state provided between the pressure head 21 and the push-pull member 22, and a connecting member 23 connected between the pressure head 21 and the push-pull member 22, one end of the connecting member 23 being fixedly connected to the pressure head 21, the push-pull member 22 being slidably connected to the connecting member 23, and a limit member for preventing the push-pull member 22 from slipping off the connecting member 23 being provided at the other end of the connecting member 23. The elastic telescopic member 24 is in a compressed state, and the elastic force generated can keep the pressure head 21 and the push-pull member 22 in a taut state, so that when the pressure head 21 is not subjected to external force, the pressure head 21 and the push-pull member 22 can slide synchronously. When attaching the lining part, after the lining part on the pressure head 21 contacts the inner wall, as the sliding drive mechanism continues to move, the push-pull part 22 continues to slide, which will further squeeze the elastic telescopic part 24 between the push-pull part 22 and the pressure head 21. The elastic force generated by the elastic telescopic part 24 acts on the pressure head 21 to achieve attachment and pressure maintenance, which can avoid hard collision when contacting the inner wall and play a buffering role.

[0031] In order to prevent the pressure head 21 from being deflected when attaching the lining member, elastic telescopic members 24 are respectively provided on opposite sides of the connecting member 23. Usually, the elastic telescopic members 24 are springs or elastic columns made of elastic material.

Usually, the push-pull member 22 of the third pressure-maintaining component 20c is set as a long strip block, which is connected to the flat plate 33 as a whole. Of course, it can also be set as a split structure and fixedly connected by fastening bolts.

The rotation axis of the output portion of the rotating drive mechanism 60 is perpendicular to the carrier plate 11, and the output portion of the rotating drive mechanism 60 is fixedly connected to the carrier plate 11. The rotating drive mechanism 60 can drive the carrier plate 11 and the first pressure-maintaining component 20a, the second pressure-maintaining component 20b, and the third pressure-maintaining component 20c installed on the carrier plate 11 to rotate, so that the first pressure-maintaining component 20a, the second pressure-maintaining component 20b, and the third pressure-maintaining component 20c are rotated to the loading position in turn. Whether loading is done manually or by a loading mechanism, the operation is very convenient. Typically, the rotating drive mechanism 60 is a stepping motor, but it can also be an electric turntable.

[0040] Specifically, the mechanism further includes a connecting plate 13 spaced apart from the upper side of the carrier plate 11, a plurality of first columns 14 spaced apart between the circumferential edges of the connecting plate 13 and the circumferential edges of the carrier plate 11, a support plate 15 spaced apart from the mounting plate 12, and a plurality of second columns 16 spaced apart between the circumferential edges of the support plate 15 and the circumferential edges of the mounting plate 12.

[0041] In order to facilitate the accurate rotation of the first pressure-maintaining component 20a, the second pressure-maintaining component 20b, and the third pressure-maintaining component 20c to the loading position, a disc is fixed on the output part of the rotating drive mechanism 60, and a first detection part, a second detection part, and a third detection part are respectively provided on the disc corresponding to the first pressure-maintaining component 20a, the second pressure-maintaining component 20b, and the third pressure-maintaining component 20c.

[0043] The swing drive mechanism 70 can drive the carrier plate 11 and the first, second, and third pressure-maintaining assemblies 20a, 20b, and 20c mounted thereon to rotate away from the bracket 80. This allows the outer side of the pressure head 21 to be tilted when the first, second, and third pressure-maintaining assemblies 20a, 20b, and 20c are positioned at the loading position, facilitating material loading. Typically, the swing drive mechanism 70 is a pneumatic cylinder, but it can also be an electric cylinder.

[0045] In some other embodiments, the mounting plate 12 may also be directly fixed on the slide plate 90 , in which case the swing drive mechanism 70 is not required.

[0046] In an embodiment of the present invention, since an adhesive layer is provided on the attachment side of the lining part and a protective film is provided on the outer side of the adhesive layer, the protective film needs to be torn off before attachment.
