It will be appreciated that in other embodiments the number of dwell stations 11 may also be one, three, four, five or more.

The pressure maintaining assembly 20 is slidably disposed at one side of the base 10 and corresponds to the at least one pressure maintaining station 11. In the present embodiment, the pressure holding unit 20 is provided corresponding to the two pressure holding stations 11, and the pressure holding unit 20 is movable between the two pressure holding stations 11. The pressure maintaining assembly 20 includes a pressure head 21, a pressure head assembly 22 and at least one first elastic member 23, the pressure head assembly 22 is slidably connected to the base 10, so that the pressure maintaining assembly 20 can move between the two pressure maintaining stations 11. The pressing head 21 is slidably disposed on the pressing head assembly 22, the at least one first elastic member 23 is connected between the pressing head 21 and the pressing head assembly 22, and when the pressing head assembly 22 moves to any one of the pressure maintaining stations 11, the pressing head 21 can vertically press the first workpiece 200 and/or the second workpiece 300.

In some embodiments, the number of the first elastic members 23 is four, and the first elastic members 23 may be springs.

It is understood that in other embodiments, the number of the first elastic members 23 may be one, two, three, five, six or more according to the shape of the ram 21 and the pressure of the dwelling. The first elastic member 23 may be a member having elasticity such as rubber.

One implementation of the pressure maintaining device 100 is generally as follows:

Under the elastic action of the first elastic member 23, the pressing head 21 can be adaptively adjusted according to the inclination angles of the first workpiece 200 and the second workpiece 300, so that the pressing head 21 can vertically press the first workpiece 200 and the second workpiece 300, no gap exists between the pressing head 21 and the first workpiece 200 and the second workpiece 300, the pressing force between the pressing head 21 and the first workpiece 200 and the second workpiece 300 is ensured to be uniform, the second workpiece 300 and the first workpiece 200 are pressed in place, and the bonding stability between the first workpiece 200 and the second workpiece 300 is ensured.

It should be noted that, the pressing head 21 vertically presses the first workpiece 200 and/or the second workpiece 300, which can be understood as follows: depending on the type of workpiece and the location of the bond, the indenter 21 may press only the first workpiece 200 or the second workpiece 300 vertically, or the indenter 21 may press the first workpiece 200 while pressing the second workpiece 300.

Referring to fig. 2, in the present embodiment, the pressure maintaining device 100 may further include a positioning assembly 30 disposed on the base 10, wherein the positioning assembly 30 is used for positioning the first workpiece 200 such that the first workpiece 200 and the second workpiece 300 are located at the correct pressure maintaining station 11. The positioning assembly 30 is further used for fixing the first workpiece 200, so as to prevent the first workpiece 200 from shifting when the pressing head 21 presses the second workpiece 300 against the first workpiece 200, thereby preventing the first workpiece 200 from being bonded to the second workpiece 300.

In some embodiments, the positioning assembly 30 may include an inner strut 31, an inner retainer 32, and a plurality of outer retainers 33. The plurality of outer limiting members 33 and the plurality of inner limiting members 32 are used to limit the first workpiece 200 in a first direction and a second direction perpendicular to the first direction.

The number of the inner supporting members 31 is two, and the two inner supporting members 31 are arranged opposite to the inner limiting member 32. The number of the outer limiting members 33 is six, and the outer limiting members are respectively disposed in the circumferential direction of the two inner supporting members 31 and the inner limiting member 32.

One implementation of the positioning assembly 30 is generally as follows: firstly, a first workpiece 200 bonded with a second workpiece 300 is placed on a base 10, and an inner limiting member 32 and two inner supporting members 31 are both positioned on the inner side of the first workpiece 200; then, the inner supporting member 31 is activated, and the inner supporting member 31 moves toward a direction close to the pressure maintaining assembly 20 along the first direction, so that the inner supporting member 31 and the corresponding outer limiting member 33 clamp one sidewall of the first workpiece 200, thereby ensuring that the first workpiece 200 is fixed. After the pressure maintaining assembly 20 maintains the pressure of the second workpiece 300 on the first workpiece 200, the inner supporting member 31 is activated, and the inner supporting member 31 moves in the direction away from the pressure maintaining assembly 20 along the first direction, so that the inner supporting member 31 and the corresponding outer limiting member 33 release the first workpiece 200, and the first workpiece 200 and the second workpiece 300 are taken out.

Referring to fig. 3, in the present embodiment, the pressure maintaining device 100 may further include inner supporting driving mechanisms 34 corresponding to the inner supporting members 31 one by one, and the inner supporting driving mechanisms 34 are configured to move the inner supporting members 31 along the first direction.

The third elastic member 343 may be a spring.

It is understood that in other embodiments, the number of the third elastic members 343 may also be two, and two third elastic members 343 are respectively disposed between two outer sidewalls of the inner support connecting member 342 and an inner sidewall of the inner support sliding cavity 3411. Or the number of the third elastic members 343 may also be three, four or more. The third elastic member 343 may be a member having elasticity such as rubber.

One implementation process of the inner supporting member 31 driven by the inner supporting driving mechanism 34 to move along the first direction is generally as follows: firstly, before the first workpiece 200 is placed, the inner support member 31 is manually or robotically shifted to the side far away from the pressure head assembly 22; then, the first workpiece 200 is placed; the inner supporting member 31 is further loosened, and the inner supporting member 31 and the inner supporting connecting member 342 move toward the direction close to the pressing head assembly 22 under the elastic action of the third elastic member 343, so that the inner supporting member 31 moves along the first direction to cooperate with the corresponding outer limiting member 33 to clamp the first workpiece 200.

It is understood that, in other embodiments, the inner supporting member driving mechanism 34 may also be a cylinder, and the cylinder is connected to the inner supporting member 31, so as to realize the movement of the inner supporting member 31 along the first direction. The inner support driving mechanism 34 may also be another component capable of driving the inner support 31 to perform a linear motion. In this way, automation of the movement of the inner stay 31 can be achieved.

The cover 40 has a substantially plate shape and is used to fix the first workpiece 200 in cooperation with the base 10. The base 10 is provided with a cover positioning part 13, and the cover positioning part 13 is used for clamping the cover 40, so that the cover 40 clamps the first workpiece 200 along the third direction. Specifically, the cover plate positioning elements 13 and the positioning assembly 30 are located on the same side of the base 10, the cover plate positioning elements 13 are substantially rod-shaped, the number of the cover plate positioning elements 13 is four and corresponds to the locking portions 41 one by one, the cover plate positioning elements 13 have a guiding function and are also used for being connected with the locking portions 41 of the cover plate 40, so that the cover plate 40 is matched with the base 10 to fix the first workpiece 200.

For convenience of explanation, the third direction is defined as a Z-axis direction as shown in fig. 2.

Thus, when the pressing head 21 vertically presses the first workpiece 200 and the second workpiece 300, the pressing head 21 can also adsorb the second workpiece 300, so that when the second workpiece 300 is bonded and pressure-maintained with the first workpiece 200, the second workpiece 300 cannot be deviated due to flowability of glue; meanwhile, as the pressure head 21 absorbs the second workpiece 300, the second workpiece 300 and the first workpiece 200 can be bonded according to preset precision, and the bonding precision between the first workpiece 200 and the second workpiece 300 is ensured to meet the requirement.

In some embodiments, the side of the ram 21 facing away from the ram assembly 22 is provided with a recess 212, and two sides of the recess 212 are respectively provided with a first abutting surface 213 and two second abutting surfaces 214 arranged on two sides of the first abutting surface 213, and the first abutting surface 213 and the second abutting surfaces 214 are both substantially planar.

In this way, the pressing head 21 is realized to press the first workpiece 200 and the second workpiece 300.

It is understood that in other embodiments, the recess 212 may be omitted.

Referring to fig. 7, in some embodiments, in a direction in which the pressing head 21 vertically presses the first workpiece 200 and the second workpiece 300, i.e., in a direction perpendicular to the first pressing surface 213 and the second pressing surface 214, a height difference H exists between the first pressing surface 213 and the second pressing surface 214, and the height of the first pressing surface 213 is higher than that of the second pressing surface 214. In this way, the indenter 21 can press the second workpiece 300 into the first workpiece 200 by the height difference H, thereby ensuring that the second workpiece 300 and the first workpiece 200 can be bonded with a predetermined accuracy.

It is understood that in other embodiments, the height of the first abutting surface 213 may be less than or equal to the height of the second abutting surface 214 according to the type of the workpiece and the precision of the adhesion.

In this way, the indenter 21 maintains the pressure for a certain time against the first workpiece 200 and the second workpiece 300.

After the pressure maintaining is finished, firstly, the vacuum generating device is closed, so that the adsorption holes 211 of the pressure head 21 stop adsorbing the second workpiece 300; then, the pressure maintaining connecting member 222 is pulled in a direction away from the base 10, and the second elastic member 225 is utilized to separate the clamping member 2241 of the pressure maintaining assembly 20 from the clamping groove 121 of the clamping portion 12; further moving the pressure maintaining connecting member 222 along the extending direction of the slide rail 14 of the base 10, and sliding the sliding member 223 along the slide rail 14 of the base 10 to enable the pressure maintaining assembly 20 to be located at another pressure maintaining station 11 or at another position where the pressure head 21 does not press the first workpiece 200 and the second workpiece 300; the inner supporting member 31 and the corresponding outer limiting member 33 are further used to release one side wall of the first workpiece 200 by the inner supporting driving mechanism 34, so as to take out the first workpiece 200 and the second workpiece 300. At this point, the pressure holding of the first workpiece 200 and the second workpiece 300 is completed.

According to the pressurizer 100 provided by the utility model, based on the elastic action of the first elastic piece 23, the pressure head 21 can be adjusted in a self-adaptive manner according to the inclination angles of the first workpiece 200 and the second workpiece 300, so that the pressure head 21 can vertically press the first workpiece 200 and the second workpiece 300, no gap exists between the pressure head 21 and the first workpiece 200 and the second workpiece 300, the pressing force between the pressure head 21 and the first workpiece 200 and the second workpiece 300 is uniform, the second workpiece 300 and the first workpiece 200 are pressed in place, and the bonding stability between the first workpiece 200 and the second workpiece 300 is ensured. Meanwhile, the second workpiece 300 is adsorbed on the basis of the adsorption hole 211 of the pressure head 21, so that the second workpiece 300 can be adhered to the first workpiece 200 according to preset adhesion precision, and the adhesion precision between the first workpiece 200 and the second workpiece 300 is ensured to meet the requirement.
