Preferably, the water-cooling channel H202b may be arranged according to the position and area of the bearing surface S20 to ensure that the water-cooling channel H202b can substantially uniformly cool the bearing surface S20. Illustratively, a plurality of water-cooling channels H202b are disposed in the jig base 20, the plurality of water-cooling channels H202b are disposed in parallel and extend along the length direction of the jig base 20, and two adjacent water-cooling channels H202b are communicated with each other through a connecting channel H202 c. In a specific application, the water inlet H2021 may be connected to a water supply device through which cooling water is supplied into the water-cooled passage H202b, and the water outlet H2022 may be connected to an external container. In addition, the bearing surface S20 on the jig base 20 is adapted to the back plate to be bonded, and can be attached to the back plate, for example, if the bottom surface of the back plate is a plane, the bearing surface S20 is also a plane adapted to the back plate.

The lens floating support is embedded in the jig base 20 and can elastically float in the vertical direction, and when the back plate is pressed and attached to the bearing surface S20, the lens floating support elastically abuts against the lens area.

That is, the lens floating mount is for supporting the lens area on the back plate. The lens floating mount can slide in a vertical direction with respect to the jig base 20 and has elasticity. In the pressure maintaining process, the pressurizing and heating mechanism 30 applies downward pressure to the back plate and the workpiece assembled on the back plate, so that the back plate is pressed and attached to the bearing surface S20 of the jig base 20, at this time, the lens area on the back plate is located above the lens floating support table, and the lens floating support table elastically abuts against the lens area to provide an upward elastic supporting effect for the lens area.

It should be noted that, since the lens area protrudes downward from the bottom surface of the backplate, and different backplates have a certain size error, the height of the lens area protruding downward also has a size error. If set up the recess that corresponds with the camera lens region on tool seat 20, then to the backplate of difference, because size error's existence, when the backplate was placed on tool seat 20 for a few, the camera lens region can not contact with the bottom surface of recess, has leaded to the camera lens region can not obtain reliable support, finally causes the bonding between backplate and other parts inhomogeneous, and the plane degree is poor.

In this application, tool seat 20 and the unsteady saddle of camera lens set up independently respectively, and when the backplate was placed on tool seat 20, the bottom surface and the loading surface S20 contact of backplate utilized loading surface S20 to support the bottom surface of backplate, and the camera lens region carries out elastic support through the unsteady saddle of independent camera lens, so, can ensure that the bottom surface of backplate and camera lens region homoenergetic can obtain reliable support to, can adapt to the backplate of different size errors.

On the other hand, the lens floating support platform can elastically float, when the back plate is pressed and attached to the bearing surface S20 by the pressurizing and heating mechanism 30, the lens area is elastically contacted with the lens floating support platform, and the lens floating support platform is used for providing elastic support for the lens area, so that the support is reliable and stable, the uniform compression of the lens area and other areas is facilitated, the uniform and firm bonding between the workpiece and the back plate is ensured, the flatness is better, and the elastic support can also play a role in buffering and protecting the lens area of the back plate.

Referring to fig. 1 and 3, in an embodiment of the present invention, the top surface of the lens floating holder is located below the bearing surface S20 at a predetermined distance, which is less than the height of the lens region protruding downward on the back plate.

That is, after the lens floating mount is installed in the jig base 20, a predetermined distance is provided between the top surface of the lens floating mount and the bearing surface S20 of the jig base 20, and the predetermined distance is smaller than the height of the lens region protruding downward on the back plate, so that when the back plate is pressed and attached to the bearing surface S20 of the jig base 20 by the pressure heating mechanism 30, the lens region on the back plate can generate downward pressure on the lens floating mount, thereby ensuring that the lens floating mount generates upward elastic supporting effect on the lens region. In addition, the top surface of the lens floating bracket is positioned below the bearing surface S20, so that a groove is formed between the top surface of the lens floating bracket and the bearing surface S20 of the jig seat 20, when the back plate is tightly attached to the bearing surface S20 of the jig seat 20, the lens area is positioned in the groove and the compression amount of the lens floating bracket is not too large, and further, the acting force of the elastic support between the lens area and the lens floating bracket is not too large, so that the relatively proper supporting acting force is kept, and the damage caused by the too large stress of the lens area is prevented.

In addition, when the back plate is deformed, some of the suction holes H202d are not sucked to the back plate, and the negative pressure of the suction holes H202d is not normal, so that it can be determined whether the back plate is deformed.

It should be noted that, in order to ensure that each area of the back plate keeps being smoothly attached to the carrying surface S20, a plurality of suction holes H202d may be dispersedly disposed on the carrying plate 202, for example, the suction holes H202d are disposed at each corner of the carrying surface S20, so that the back plate is more easily attached to the carrying surface S20 in a smooth manner under the condition that the number of the suction holes H202d is small.

The support table 12 is arranged at the upper end of the sliding column 11, and the top surface of the support table 12 is matched with the lens area to support the lens area of the backboard. Preferably, the size of the platform 12 is matched with the size of the lens area of the backboard, and when the backboard is placed on the jig base 20, the lens area on the backboard is just opposite to the platform 12 up and down, so that the lens area is supported by the platform 12.

The first elastic element 13 is disposed between the bottom of the sliding column 11 and the jig base 20, and is used for providing an upward elastic force to the sliding column 11. In the pressure maintaining process, the pressurizing and heating mechanism 30 of the pressure maintaining device moves downward to press the back plate and the workpiece assembled on the back plate, so that the back plate is pressed downward, the lens area on the back plate can be abutted against the support table 12, and the first elastic member 13 is in a compressed state, so that the support table 12 elastically supports the lens area.

An adaptive limiting pin 15 penetrates through the pin hole H10b, and the limiting pin 15 penetrates through the limiting groove H11 so as to limit the sliding stroke of the sliding column 11 in the vertical direction through the limiting groove H11. That is, the height dimension of the stopper groove H11 in the vertical direction on the slide post 11 is larger than the radial dimension of the stopper pin 15.

When the pallet 12 is pressed to move downwards to the limit position, the top surface of the limit groove H11 is abutted against the limit pin 15, the maximum distance of the downward sliding of the sliding column 11 is limited by the top surface of the limit groove H11, and when the pressure applied to the pallet 12 is removed, the elastic force of the first elastic piece 13 forces the sliding column 11 and the pallet 12 thereon to move upwards, when the pallet 12 moves upwards to the limit position, the bottom surface of the limit groove H11 is abutted against the limit pin 15, and the maximum distance of the upward sliding of the sliding column 11 is limited by the bottom surface of the limit groove H11, so that the pallet 12 can float reliably and stably up and down, and the structure is simple and the assembly is convenient.

The upper end of the sliding column 11 extends upward into the through hole H202a of the loading plate 202, and the pallet 12 is fixed to the upper end of the sliding column 11, so that the pallet 12 can stably and reliably float in the through hole H202 a. In addition, simple structure, convenient assembling.

Since the pallet 12 is pressed by the first elastic member 13 and then transferred to the pressure sensor 14 during the pressure holding process, and the pressure is high, the pressure sensor 14 is easily damaged during a long-term use, and thus, the pressure sensor 14 needs to be replaced.

In this embodiment, the first quick-release opening H20b and the second quick-release opening H20c are disposed on the side of the lower jig base 20, when the pressure sensor 14 needs to be replaced, the limit pin 15 can be detached from the first quick-release opening H20b, at this time, the pressure of the first elastic member 13 on the pressure sensor 14 is released, and then the pressure sensor 14 is detached from the second quick-release opening H20c, so that the maintenance is convenient, and the whole jig does not need to be disassembled.

Referring to fig. 3 to 4, in an example of the present invention, the present invention further includes a stopper 204, and the stopper 204 is located in the second quick release opening H20c and fixed to the jig base 20 by a fastener, so as to limit the pressure sensor 14 in the sinking groove H201 a.

In a state where the pressure sensor 14 is normally used, the stopper 204 can restrict the pressure sensor 14 in the fitting groove, thereby preventing problems such as instability and positional deviation of the pressure sensor 14. When the pressure sensor 14 is damaged, the stopper 204 can be disassembled first, the second quick-release opening H20c is opened, the limit pin 15 is disassembled, and then the pressure sensor 14 is taken out from the second quick-release opening H20c, so that the disassembly is convenient and simple.

Referring to fig. 1 to 4, in an embodiment of the invention, the elastic connection mechanism 203 includes a plurality of guide columns 2031, a plurality of second elastic members 2032 and a plurality of C-shaped members 2033, wherein the plurality of guide columns 2031 are arranged between the base 201 and the bearing plate 202 at intervals, so that the bearing plate 202 is slidable in a vertical direction with respect to the base 201.

The plurality of second elastic members 2032 are distributed between the bottom plate and the carrier plate 202, an upper end of each second elastic member 2032 abuts against the carrier plate 202, and a corresponding segment of each elastic member abuts against the bottom plate. The second elastic member 2032 is exemplarily a spring, and a plurality of springs are distributed between the base plate and the carrier plate 202, and the carrier plate 202 can be floated in a vertical direction by an elastic action provided by the plurality of springs.

The C-shaped members 2033 are arranged around the jig base 20 at intervals, each C-shaped member 2033 has an opening H203, an upper stop edge 2033b above the opening H203, and a lower stop edge 2033a below the opening H203, the edges of the bottom plate and the carrier plate 202 are located in the opening H203 of the C-shaped member 2033, the bottom plate abuts against the lower stop edge 2033a, and the carrier plate 202 abuts against the upper stop edge 2033b, so that the floating distance of the carrier plate 202 is limited by the C-shaped member 2033.

In order to maintain the position relationship between the C-shaped element 2033 and the bottom plate and the carrier plate 202, the C-shaped element 2033 may be fixed to one of the bottom plate and the carrier plate 202, for example, the upper stop edge 2033b of the C-shaped element 2033 is fixed to the carrier plate 202 by a fastener, and the lower stop edge 2033a of the C-shaped element 2033 is only located below the bottom plate and is not fixed to the bottom plate, so that the pressurizing and heating mechanism 30 pressurizes the jig base 20, and when the carrier plate 202 is pressed to move downward, the second elastic element 2032 compresses, and the lower stop edge 2033a on the C-shaped element 2033 moves downward and away from the bottom plate. When the pressure is removed by the pressure heating mechanism 30, the second elastic member 2032 pushes the bearing plate 202 to move upward, and at this time, the lower stop edge 2033a on the C-shaped member 2033 moves upward along with it until the lower stop edge 2033a abuts against the bottom plate, and the bearing plate 202 can float upward to the highest position, so that the C-shaped member 2033 is used to realize the stroke limit of the bearing plate 202, that is, the floating distance of the bearing plate 202 is limited.

It should be noted that, in the floating mechanism of the related art, a spring is disposed between two fixed plates and a floating plate, a stroke column is disposed on the fixed plate, the stroke column is in sliding fit with the floating plate and is locked at an end of the stroke column through a nut, the nut abuts against an outer side of the floating plate, and a maximum stroke of the floating plate is limited through the nut.

In this embodiment, the C-shaped member 2033 is used for limiting, and since the bottom plate abuts against the lower retaining edge 2033a and the bearing plate 202 abuts against the upper retaining edge 2033b, the structural design can bear larger impact, ensure reliable stroke limiting, and cannot fail even after long-term use.
