DETAILED DESCRIPTION

[0033] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0034] like Figure 1-Figure 7As shown, this embodiment provides a hot pressing device, which includes a driving device (not shown in the figure), a mounting plate 100, and at least one supporting member 200 arranged on the mounting plate 100. The driving device can be a motor, a cylinder, a mechanical arm, etc. The mounting plate 100 is connected to the driving device. A workbench 300 is arranged below the supporting member 200. Under the drive of the driving device, the mounting plate 100 can drive at least one supporting member 200 to move in a direction toward or away from the workbench 300. A workpiece 400 to be processed is arranged on the workbench 300. In this embodiment, the workpiece 400 to be processed is taken as an example of a transparent adhesive film. For example, two adhesive films are placed on the workbench 300 and stacked up and down. The driving device is started, so that the driving device drives the supporting member 200 to move toward the direction of the adhesive film through the mounting plate 100, so that the supporting member 200 squeezes the two adhesive films, thereby realizing the hot pressing treatment of the two adhesive films, and the two adhesive films can be made into a breathing bag 800 with multiple independent spaces.

[0035] Furthermore, the hot pressing device in this embodiment is described by taking one of the support members 200 on the mounting plate 100 as an example. An extrusion member 500 is also provided on the support member 200. When the support member 200 moves toward the workpiece 400 to be processed, the support member 200 indirectly realizes the extrusion effect on the workpiece 400 through the extrusion member 500, that is, the extrusion member 500 at least partially protrudes from the outer surface of the support member 200. The temperature of the extrusion member 500 is variable. When the workpiece 400 to be processed needs to be hot pressed, the temperature of the extrusion member 500 can be increased. When the hot pressing operation is not required, the temperature of the extrusion member 500 can be decreased, so as to facilitate use.

[0036] Furthermore, the support member 200 performs hot pressing operation on the workpiece 400 indirectly through the extrusion member 500, so it can be known that the extrusion member 500 has an extrusion surface 510 close to the workpiece 400, and the extrusion member 500 performs hot pressing operation on the workpiece 400 through the extrusion surface 510. A protective plate 600 is also provided on the support member 200, and the protective plate 600 has a first end surface 610 close to the workpiece 400, wherein the first end surface 610 can be flush with the extrusion surface 510 on one hand, and can also be further away from the support member 200 than the extrusion surface 510 on the other hand, that is, close to the workpiece 400.

[0037] When the first end face 610 is arranged flush with the extrusion face 510, the protection plate 600 can be located outside the extrusion member 500 and can cover the extrusion member 500 in the horizontal X direction. Driven by the driving device, the support member 200 can simultaneously drive the extrusion member 500 and the protection plate 600 to move toward the direction close to the workpiece 400 to be processed. In this process, the extrusion face 510 and the first end face 610 are located in the same plane. When the surface of the workpiece 400 to be processed is flat, the extrusion face 510 and the first end face 610 can simultaneously contact the surface of the workpiece 400 to be processed and extrude the workpiece 400, and then the extrusion face 510 performs hot pressing treatment on the workpiece 400.

[0038] When the first end face 610 is arranged to be farther away from the support member 200 than the extrusion surface 510, the protective plate 600 can be located on the outside of the extrusion member 500 and can cover the extrusion member 500 in the horizontal X direction. Driven by the driving device, the support member 200 can simultaneously drive the extrusion member 500 and the protective plate 600 to move toward the direction close to the workpiece 400 to be processed. In this process, since the first end face 610 is closer to the workpiece 400 to be processed, when the surface of the workpiece 400 to be processed is flat, the first end face 610 can contact the workpiece 400 to be processed before the extrusion surface 510, and the extrusion surface 510 will contact the workpiece 400 to be processed only after the first end face 610 contacts the workpiece 400 to be processed, and then the extrusion surface 510 performs hot pressing treatment on the workpiece 400 to be processed.

[0039] It is worth mentioning that the protective plate 600 in this embodiment can cover the extrusion piece 500 protruding from the outer surface of the support member 200 in the horizontal X direction, and can prevent the staff from being burned by direct contact with the extrusion piece 500. In addition, during the process of the extrusion piece 500 performing hot pressing treatment on the workpiece 400, the protective plate 600 can assist the extrusion piece 500 in extruding the workpiece 400 through the first end surface 610, and can improve the stability of the position of the workpiece 400 during the hot pressing treatment. In particular, when the first end surface 610 is arranged farther away from the support member 200 than the extrusion surface 510, the first end surface 610 can pre-position the workpiece 400 before the extrusion surface 510 contacts the workpiece 400.

[0040] In some embodiments, a guide groove 210 is provided on the side wall of the support member 200 and extends in the direction of the workpiece 400, that is, in the vertical Y direction, and is in the shape of a long strip, and a movable block 620 that can be snap-connected in the guide groove 210 is provided on the protective plate 600, wherein the movable block 620 can move back and forth in the guide groove 210 along the length direction of the guide groove 210; through the cooperation of the guide groove 210 and the movable block 620, the protective plate 600 can be movably connected to the support member 200, so that the protective plate 600 can move toward or away from the workpiece 400 to be processed on the support member 200.

[0041] When not in contact with the workpiece 400, the support member 200 is located above the workbench 300 under the action of the driving device, that is, the support member 200 is located above the workpiece 400. At this time, the protective plate 600 drives the movable block 620 to be located at the end of the guide groove 210 close to the workpiece 400 under the action of its own gravity, that is, the protective plate 600 is at the lowest position relative to the support member 200. When the protective plate 600 contacts the workpiece 400 and generates a squeezing effect with the workpiece 400, since the force is mutual, under the squeezing effect of the workpiece 400, the protective plate 600 will move as a whole toward the direction close to the mounting plate 100 through the movement of the movable block 620 in the guide groove 210.

[0042] It is understandable that the protective plate 600 is movably connected to the support member 200. The protective plate 600 can not only still cover the extrusion member 500 in the horizontal X direction to avoid accidental touch and burns of the staff, but also makes the use of the protective plate 600 more flexible.

[0043] Specifically, the protective plate 600 can assist the extrusion member 500 in extruding the workpiece 400, and through the extrusion between the protective plate 600 and the workpiece 400, the protective plate 600 moves toward the direction close to the mounting plate 100, which can prevent the protective plate 600 from exerting too much pressure on the workpiece 400, and prevent the workpiece 400 from being damaged by the large pressure of the protective plate 600. Further, after the protective plate 600 exerts pressure on the workpiece 400, the staff can manually move the protective plate 600 so that the protective plate 600 moves toward the direction close to the mounting plate 100, so that the protective plate 600 releases the pressure on the workpiece 400, so that the workpiece 400 near the extrusion surface 510 can be processed, such as unfolded, so as to avoid the wrinkles of the workpiece 400 after the heat treatment, and then the protective plate 600 is put down, so that the first end surface 610 re-extrudes and positions the workpiece 400 through the movement of the movable block 620 in the guide groove 210.

[0044] Furthermore, in some embodiments, in order to facilitate the manual operation of the protective plate 600 by the staff, an operating handle (not shown in the figure) can be provided on the protective plate 600 .

[0045] It should be noted that in order to achieve the snap-fit ​​connection between the movable block 620 and the guide groove 210, the guide groove 210 can be set as a T-slot with a T-shaped cross-section, and the movable block 620 can be set as a T-block with a T-shaped cross-section. As long as the snap-fit ​​cooperation between the movable block 620 and the guide groove 210 can be achieved, there is no special limitation on this; and the movable protective plate 600 on the support member 200 can cover the extrusion member 500 during the entire hot pressing process to improve safety.

[0046] In some embodiments, an installation groove 220 capable of accommodating the protective plate 600 is provided on the side wall of the support member 200, and the above-mentioned guide groove 210 is provided on the side wall of the installation groove 220. The protective plate 600 can be movably set in the installation groove 220 through the cooperation of the movable block 620 and the guide groove 210.

[0047] By providing the mounting groove 220 on the support member 200 and disposing the protective plate 600 in the mounting groove 220 , the size of the overall mechanism can be reduced and the occupied space can be reduced.

[0048] In some embodiments, a return spring (not shown in the figure) is arranged between the protective plate 600 and the mounting groove 220. Specifically, the return spring is arranged between the end of the protective plate 600 away from the workpiece to be processed 400 and the end of the mounting groove 220 close to the mounting plate 100. The return spring can maintain the protective plate 600 with a tendency to move toward the direction close to the workpiece to be processed 400.

[0049] It is understandable that the protective plate 600 can be pushed under the action of the return spring, and the protective plate 600 , combined with its own gravity, can facilitate the movable block 620 to move in the guide groove 210 toward the workpiece 400 to be processed.

[0050] Specifically, when not working, under the action of the return spring and gravity, the protective plate 600 is at the lowest point relative to the support member 200, and the extrusion member 500 is covered at this time; when hot pressing treatment is performed, when the protective plate 600 contacts the workpiece 400 to be processed and is extruded with the workpiece 400, under the action of the workpiece 400, the return spring can be compressed, so that the protective plate 600 moves toward the mounting plate 100; if the staff needs to operate the protective plate 600 afterwards, the return spring can be further compressed to move the protective plate 600 toward the mounting plate 100, and then the workpiece 400 to be processed near the extrusion surface 510 can be processed. After the processing, under the action of the return spring, the protective plate 600 can be automatically pressed again on the workpiece 400 to be processed.

[0051] When the hot pressing treatment is completed, the support member 200 moves as a whole away from the workpiece 400 to be processed. During this process, the return spring gradually expands, and the return spring pushes the protective plate 600 to move away from the mounting plate 100 relative to the support member 200 until the protective plate 600 moves to the lowest point relative to the support member 200.

[0052] In particular, by setting the return spring, the protective plate 600 can be pushed better, so that the position of the protective plate 600 changes with the movement of the support member 200. During the entire hot pressing process, the protective plate 600 can cover the extrusion member 500 to improve safety.

[0053] In some embodiments, a power supply device (not shown in the figure) is further provided on the hot pressing device, and the extrusion piece 500 is connected to the power supply device by wires. The extrusion piece 500 in this embodiment is made of a conductive material. When the power supply device is started and supplies power to the extrusion piece 500, the temperature of the extrusion surface 510 of the extrusion piece 500 can be increased, thereby achieving variable temperature of the extrusion piece 500. The power supply of the power supply device increases the temperature of the extrusion surface 510 of the extrusion piece 500, so that the extrusion piece 500 can be better subjected to hot pressing treatment on the workpiece 400.

[0054] Preferably, the power supply device can adjust the current supplied to the extrusion piece 500, and thus can adjust the temperature of the extrusion surface 510 of the extrusion piece 500, so as to facilitate use.

[0055] In some embodiments, the support member 200 has a first side wall 230 facing the workpiece 400 to be processed. A snap-fit ​​groove 231 is provided on the first side wall 230 , and the extrusion member 500 is snap-fitted and installed in the snap-fit ​​groove 231 .

[0056] Specifically, the extrusion piece 500 is connected to the power supply device through wires and then installed in the clamping groove 231, or the extrusion piece 500 is first installed in the clamping groove 231 and then connected to the power supply device through wires. Through the setting of the clamping groove 231, the installation of the extrusion piece 500 on the support piece 200 can be better achieved.

[0057] In some embodiments, the support member 200 also has a second side wall 240 and a third side wall 250 adjacent to the first side wall 230, and the second side wall 240 and the third side wall 250 are arranged opposite to each other, and the snap-in groove 231 on the first side wall 230 extends in the length direction of the support member 200 in the shape of a long strip and opens on the second side wall 240 and the third side wall 250 respectively.

[0058] Through the opening of the snap-fitting groove 231 on the second side wall 240 and the third side wall 250, the extrusion piece 500 can be installed into the snap-fitting groove 231 or removed from the snap-fitting groove 231 through the opening on the second side wall 240 or the opening on the third side wall 250, thereby realizing the detachable installation of the extrusion piece 500 and the snap-fitting groove 231, which is convenient for operation and use.

[0059] In some embodiments, the cross-section of the snap-in groove 231 is a constricted shape that is narrow on the outside and wide on the inside, and the cross-sectional shape of the extrusion piece 500 matches the cross-sectional shape of the snap-in groove 231. When the extrusion piece 500 is snap-fitted and installed into the snap-in groove 231 from the opening on the second side wall 240 or the third side wall 250, the snap-in groove 231 can limit the extrusion piece 500 in the vertical Y direction, thereby preventing the extrusion piece 500 from falling and improving safety in use.

[0060] It is understandable that, in some embodiments, the snap-fit ​​groove 231 may be set as a T-shaped groove, as long as the snap-fit ​​groove 231 can limit the extrusion member 500 in the vertical Y direction, and there is no special limitation on this.

[0061] In some embodiments, a stopper 700 is provided on the second side wall 240 and / or the third side wall 250 of the support member 200, the first end of the stopper 700 is connected to the support member 200, and the second end of the stopper 700 extends to the opening of the clamping groove 231. After the extrusion member 500 is installed in the clamping groove 231, the stopper 700 is installed on the support member 200, so that the stopper 700 can limit the extrusion member 500 in the clamping groove 231 in the length direction of the support member 200, so as to prevent the extrusion member 500 from shaking, shifting or falling in the clamping groove 231. When it is necessary to remove the extrusion member 500 from the clamping groove 231, it is only necessary to remove the stopper 700 first.

[0062] In some embodiments, the first end of the retaining member 700 is rotatably and / or detachably connected to the support member 200. Specifically, a positioning hole 260 is provided on the support member 200, and a positioning column (not shown in the figure) is provided on the first end of the retaining member 700, and the positioning column can be threadedly connected to the positioning hole 260, so that the retaining member 700 can be rotatably and detachably attached to the support member 200.

[0063] It is understandable that by rotating or disassembling the retaining member 700 on the support member 200, the second end of the retaining member 700 can be removed from the opening of the clamping groove 231 on the second side wall 240 and / or the third side wall 250, so that the extrusion member 500 can be disassembled and assembled in the clamping groove 231. By rotating or installing the retaining member 700 on the support member 200, the second end of the retaining member 700 can be extended into the opening of the clamping groove 231 on the second side wall 240 and / or the third side wall 250, so that the extrusion member 500 in the clamping groove 231 can be limited.

[0064] In some embodiments, since the extrusion member 500 has a relatively high temperature during operation, in order to increase the service life, the support member 200, the protective plate 600 and the blocking member 700 may be made of high temperature resistant materials.

[0065] It should be noted that since the main function of the protective plate 600 is to cover the extrusion part 500 to prevent the staff from accidentally touching it and causing burns, the protective plate 600 should not have thermal conductivity so that the staff can safely operate the protective plate 600 to improve safety.

[0066] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
