The top cover and the base can be close to or far from each other, so that the mounting surface 210 can be close to the groove wall of the positioning groove 110 or exit from the positioning groove 110. The shape of the positioning groove 110 is set according to the shape of the electronic device cover 102, so that the plane 301 and the bending 302 of the electronic device cover 102 can be respectively attached to the groove bottom 111 and the concave arc wall 112 of the positioning groove 110. The straight region 211 of the mounting surface 210 has a shape and a size corresponding to the groove bottom 111 of the positioning groove 110, and the curved region 212 has a shape and a size corresponding to the concave arc wall 112, so that the mounting surface 210 can be close to the groove wall of the positioning groove 110 after the upper cover and the base are close to each other. In the embodiment of the application, the installation face 210 through with the mount pad 201 corresponds the setting with the constant head tank 110, make and install the electronic equipment lid 102 in the constant head tank 110 of fixing base 101, with the bubble celloidin 400 be located the installation face 210 of mount pad 201, then be close to back each other with upper cover and base, the bubble celloidin 400 takes place crooked and electronic equipment's crooked 302 adaptation, in order to reduce the gap between bubble celloidin 400 and the electronic equipment, thereby improved the laminating degree of the crooked 302 of bubble celloidin 400 in the electronic equipment lid 102.

The fixing base 101 and the mounting base 201 can be made of bakelite, but not limited to bakelite, and can also be made of other materials with higher strength, so that the deformation and fracture resistance of the fixing base 101 and the mounting base 201 can be ensured, and the stability and reliability of the fixing base 101 and the mounting base 201 can be improved. In some examples, the upper cover further includes a cover 102, the cover 102 is connected to a side of the fixing base 101 facing away from the positioning slot 110, and a hardness of the cover 102 is greater than a hardness of the fixing base 101; and/or the base further comprises a bottom plate 202, the bottom plate 202 is connected to the side of the mounting seat 201 away from the mounting surface 210, and the hardness of the bottom plate 202 is greater than that of the mounting seat 201. For example, the cover 102 and the base plate 202 may be made of other metal materials such as aluminum, etc. to ensure the hardness of the cover 102 and the base plate 202, so as to improve the hardness of the appearance surface of the mounting fixture and resist external force.

There are various ways to control the fixed seat 101 and the mounting seat 201 to approach or separate from each other, for example, the fixed seat 101 and the mounting seat 201 can be controlled by a human hand, or an air cylinder 140 can be disposed on the upper cover or the base, and the fixed seat 101 and the mounting seat 201 can approach or separate from each other through the air cylinder 140, which is not limited herein. In some examples, the base is provided with a guide post 203, the upper cover is provided with a guide hole 103, and the guide post 203 is slidably matched with the guide hole 103. That is, the guide post 203 can slide along the extending direction of the guide hole 103, so that the fixing base 101 and the mounting base 201 can be displaced according to a preset route when being close to or away from each other, thereby being capable of rapidly and accurately controlling the fixing base 101 and the mounting base 201 to be close to or away from each other, and improving the working efficiency of the mounting jig.

To improve the accuracy and the degree of attachment of the foam 400 to the electronic device cover 102, in some examples, the flat region 211 is provided with a position-limiting post 213, and the position-limiting post 213 is configured to be sleeved with a release film 500 connected to the foam 400. Particularly, from type membrane 500 has trepanning 501, during the installation, aims at spacing post 213 from the trepanning 501 of type membrane 500 for bubble celloidin 400 with from type membrane 500 install on installation face 210 after, spacing post 213 is inserted and is located trepanning 501, with the displacement of restricting from type membrane 500 and restriction bubble celloidin 400's displacement, thereby make bubble celloidin 400 install on installation face 210 according to predetermined position, improve the degree of accuracy and the laminating degree that bubble celloidin 400 laminated in electronic equipment lid 102. Note that, during installation, the release film 500 is installed in a direction in which the release film 500 faces the installation surface 210 and the foam 400 faces the positioning groove 110, so that the release film 500 can be removed after the foam 400 is attached to the electronic device cover 102.

In some examples, the straight section 211 defines a sliding hole 214, and the position-limiting column 213 telescopically engages with the sliding hole 214, such that the position-limiting column 213 has an extended state protruding from the straight section 211 and a retracted state retracted into the sliding hole 214. For example, the mounting base 201 further includes an elastic member 215, the elastic member 215 is mounted at an end of the sliding hole 214 away from the mounting surface 210, and an inner end of the limiting column 213 abuts against the elastic member 215.

The first air extractor 230 is used for extracting air from the negative pressure chamber 220, so that the suction hole 216 communicated with the negative pressure chamber 220 generates negative pressure to absorb the foam 400 on the mounting surface 210, and the foam 400 is stably positioned between the concave arc wall 112 and the bending area 212, thereby ensuring that the mounting jig can smoothly mount the foam 400 on the electronic device cover 102. The first air-extracting device 230 may be a vacuum pump, a gear pump, or the like, and is not particularly limited as long as it can extract air from the negative pressure chamber 220.

In some examples, the number of the suction holes 216 is plural, at least one suction hole 216 is opened at a portion of the flat zone 211 near the curved zone 212, and at least one suction hole 216 is opened at the curved zone 212. Because the portion of the straight region 211 close to the bending region 212 is used for supporting one side edge of the foam 400, the straight region 211 is in direct contact with the foam 400, and the suction hole 216 is formed in the straight region 211, which is beneficial to increasing the contact area between the suction hole 216 and the foam 400, so that the adsorption effect of the suction hole 216 on the foam 400 is improved. The suction holes 216 are formed in the bending area 212, so that the portion of the foam 400 which is not directly supported can be sucked, the foam 400 is integrally and stably placed on the mounting surface 210, and the mounting jig can smoothly mount the foam 400 on the electronic device cover 102.

Similarly, the second air extractor 130 is used for extracting air from the negative pressure chamber 120, so that the absorption hole 113 communicated with the negative pressure chamber 220 generates negative pressure to absorb the electronic device cover 102 on the positioning groove 110, so that the electronic device cover 102 is stably attached and positioned on the positioning groove 110, and the mounting jig can smoothly attach the foam adhesive 400 to the electronic device cover 102. The second pumping means 130 may be a vacuum pump, a gear pump, etc., and is not particularly limited as long as it can pump the negative pressure chamber 120.

In some examples, the number of the adsorption holes 113 is plural, and the plural adsorption holes 113 are provided at intervals along the extending direction of the groove bottom 111 of the positioning groove 110. Thus, the contact area between the adsorption holes 113 and the electronic device cover 102 is increased, the electronic device cover 102 is adsorbed by the adsorption holes 113 at a plurality of positions, the balance of the electronic device cover 102 mounted in the positioning groove 110 is improved, the electronic device cover 102 is not prone to left and right shaking, and the improvement of the accuracy and the laminating degree of the foam adhesive 400 attached to the electronic device cover 102 is facilitated.
