[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] like Figures 1 to 3 As shown, an embodiment of the present application provides a heating and pressure-maintaining mechanism, which includes a frame 2, a lifting drive assembly 1 is arranged on the top of the frame 2, and a first type of longitudinal guide rail assembly is arranged on one side of the frame 2, such as Figure 4 and Figure 5 As shown, a slide is installed on the first type of longitudinal guide rail assembly, and the slide is connected to the lifting drive assembly 1. A plurality of hot pressing head 7457 mechanisms are arranged on the slide, and each hot pressing head 7457 mechanism includes a base 741, a second type of longitudinal guide rail assembly 742 installed on the base 741, a moving seat 743 installed on the second type of longitudinal guide rail assembly 742, a counterweight assembly 744 for detachably connecting to the moving seat 743, and a pressing head assembly 7457 connected to the lower end of the moving seat 743, and a blocking piece 746 is connected to the lower end of the base 741, a part of which is located below the moving seat 743, and the blocking piece 746 is used to limit the moving distance of the moving seat 743. The other side of the frame 2 is provided with a plurality of weight reduction components 5, each weight reduction component 5 corresponds to each hot pressing head 7457 mechanism one by one, and also includes a plurality of connecting ropes 9, each connecting rope 9 corresponds to each weight reduction component 5 one by one, one end of the connecting rope 9 is used to be detachably connected to the corresponding moving seat 743, and the other end of the connecting rope 9 is used to pass through the fixed pulley assembly provided on the frame 2 and be connected to the corresponding weight reduction component 5. The above-mentioned fixed pulley assembly may include a front fixed pulley assembly 31 and a rear fixed pulley assembly 32.

[0046] When the product needs to be pressure-maintained, the product is first transported to the pressure-maintaining position, and then the lifting drive assembly 1 drives the slide to descend, and the slide will drive the various hot pressing heads 7457 mechanisms on it to descend together. After the slide descends to the predetermined position, it stops moving, and the pressing head assembly 7457 of each hot pressing head 7457 mechanism will apply pressure to the product below. The above-mentioned pressing head assembly 7457 is a pressing head assembly 7457 with a heating function. In this application, the pressure applied to the product is achieved by the cooperation of the counterweight assembly 744 and the weight reduction assembly 5. The counterweight assembly 744 is composed of a plurality of counterweight blocks, and the weight reduction assembly 5 is composed of a plurality of weight reduction blocks 504. Neither the counterweight block nor the weight reduction block 504 has elasticity, so the pressure applied to the product will not fluctuate up and down. Moreover, the counterweight assembly 744 and the weight reduction assembly 5 are used in combination to obtain pressure values ​​suitable for different products.

[0047] For example, no counterweight assembly 744 may be provided on the movable seat 743. In this case, without the counterweight assembly 744, the holding pressure required by the product can be met by relying solely on the overall gravity of the hot pressing head 7457 mechanism.

[0048] For another example, if the product requires a relatively large pressure holding force, a counterweight assembly 744 needs to be provided on the movable seat 743 to meet the pressure holding force required by the product. In this case, a corresponding number of counterweight blocks can be installed on the movable seat 743 according to the actual needs of the product. At this time, the connecting rope 9 may not be connected to the movable seat 743.

[0049] For another example, when the pressure holding required by the product is very small, all the counterweights are removed, but the pressure holding is still not met, the connecting rope 9 needs to be connected to the movable seat 743, and the other end of the connecting rope 9 passes through the fixed pulley assembly provided on the frame 2 and is connected to the corresponding weight reduction assembly 5. By adjusting the number and weight of the weight reduction blocks 504 on the weight reduction assembly 5, the pressure value can be reduced to the pressure holding required by the product. For another example, when the various combinations of counterweight blocks on site cannot accurately meet the pressure holding of the product, the counterweight blocks can be used in conjunction with the weight reduction blocks 504 to accurately adjust the pressure value.

[0050] Furthermore, the above-mentioned hot pressing head 7457 mechanisms of the present application are independent of each other, and each hot pressing head 7457 mechanism is provided with a counterweight component 744 and a weight reduction component 5, so that each hot pressing head 7457 mechanism can perform pressure control independently, so that the heating and pressure-maintaining mechanism of the present application can simultaneously generate different pressure values ​​to maintain pressure for different products.

[0051] Specifically, there are many implementation methods of the above-mentioned lifting drive component 1. For example, the above-mentioned lifting drive component 1 is a motor lifting module.

[0052] Specifically, two first-type longitudinal guide rail assemblies are arranged at intervals on the frame 2, and the slide is connected to the two first-type longitudinal guide rail assemblies respectively. A floating joint 603 is arranged at the top of the slide, and the floating joint 603 is connected to the above-mentioned lifting drive assembly 1. In this way, under the drive of the lifting drive assembly 1, the slide can move up and down.

[0053] Specifically, the connecting rope 9 can be a rope of the type of nylon rope, etc. A connecting pillar can be arranged on the movable seat 743, and a hole is provided on the connecting pillar for connecting with the connecting rope 9.

[0054] In one embodiment, if Figure 5 As shown, the movable seat 743 is provided with two support columns, which are spaced apart from each other. The counterweight assembly 744 includes a plurality of counterweight blocks sleeved on the support columns, and the end of each support column is detachably connected with a locking member 7441.

[0055] Specifically, the locking member 7441 is threadedly connected to the support column. After the locking member 7441 is separated from the support column, the counterweight block can be removed from the support column, or the counterweight block can be installed on the support column. When the counterweight block is adjusted, the locking member 7441 can be threadedly connected to the support column, and then each counterweight block can be fixed on the support column through the locking member 7441.

[0056] In one embodiment, based on the above, Figure 4 As shown, it also includes a fence 10 connected to the slide, and the fence 10 is used to enclose the various counterweight blocks on the moving seat 743 inside. An extension frame is set on one side of the slide, and the extension frame is installed with an in-place detection sensor 4.

[0057] Specifically, when the slide table descends to a predetermined position, the in-position detection sensor 4 generates a signal, and the lifting drive assembly 1 stops operating. The in-position detection sensor 4 may be a photoelectric sensor 605 or other types of sensors.

[0058] In one embodiment, if Figure 6 As shown, the weight reduction assembly 5 includes a mounting plate 505 connected to the frame 2, a linear bearing 503 arranged on the mounting plate 505, a guide shaft 502 slidingly matched with the linear bearing 503, a connecting pillar arranged at the upper end of the guide shaft 502, and a plurality of weight reduction blocks 504 arranged at the lower end of the guide shaft 502 and detachably connected to the guide shaft 502.

[0059] Specifically, the connection pillar is provided with a hole, and the hole is used to connect with the connection rope 9.

[0060] Specifically, a support is provided at the lower end of the guide shaft 502, and a notch can be provided on the weight-reducing block 504. The weight-reducing block 504 is inserted into the guide shaft 502 through the notch and supported by the support. It can be understood that the weight-reducing block 504 and the guide shaft 502 can also be connected in other ways.

[0061] Specifically, through the cooperation between the guide shaft 502 and the linear bearing 503, each guide shaft 502 can be raised and lowered smoothly without interfering with each other.

[0062] In one embodiment, if Figure 2 As shown, a weight reduction failure detection sensor 8 is provided on the frame 2 on the outer side of the weight reduction component 5 .

[0063] Specifically, the weight reduction failure detection sensor 8 can be a photoelectric sensor 605, etc. When the weight reduction component 5 needs to be used, the weight reduction component 5 moves upward for a distance under the traction of the connecting rope 9. During the product pressure holding stage, if a connecting rope 9 breaks, or a hot pressing head 7457 mechanism fails, causing the weight reduction component 5 to drop unexpectedly, this will trigger the weight reduction failure detection sensor 8 to generate a signal, and further countermeasures can be taken through the signal to ensure that the product can perform normal pressure holding operation.

[0064] In one embodiment, if Figure 8 As shown, the pressing head assembly 7457 includes an adapter plate assembly having a heat insulation plate 7452, a leveling mechanism connected to the adapter plate assembly, and a hot pressing head 7457 connected to the leveling mechanism, the leveling mechanism is provided with a heating assembly 7491, the adapter plate assembly is connected with a wiring terminal 747, and the wiring terminal 747 is used to be electrically connected to the heating assembly 7491.

[0065] Specifically, Figures 8 to 11 As shown, the adapter plate assembly includes an upper adapter plate 7451, a heat insulation plate 7452 and a lower adapter plate 7453 which are arranged in sequence. The upper adapter plate 7451 is connected to the movable seat 743, and the lower adapter plate 7453 is connected to the leveling mechanism. The leveling mechanism is used to adjust the hot pressing head 7457 to a horizontal state. This ensures that the hot pressing head 7457 can have good contact with the product, thereby ensuring that the product will not have poor adhesion, warping and other undesirable phenomena after pressure maintenance.

[0066] The leveling mechanism includes a first adjustment block 7454, a second adjustment block 7455 and a heating block 7456. The hot pressing head 7457 is connected to the lower end of the heating block 7456. The heating assembly 7491 is provided on the heating block 7456. The first adjustment block 7454 includes a horizontal portion 74542 and a vertical portion 74541 located on one side of the horizontal portion 74542. The horizontal portion 74542 of the first adjustment block 7454 is connected to the lower adapter plate 7453. The second adjusting block 7455 includes a main body 74551, an X-direction bolt mounting portion 74552 arranged on the main body 74551, and a Y-direction bolt mounting portion 74553 arranged on one side of the main body 74551, a plurality of first-type top screws 7492 are arranged at one end of the main body 74551 of the second adjusting block 7455, the vertical portion 74541 of the first adjusting block 7454 is supported by the first-type top screws 7492, a plurality of through holes are arranged on the X-direction bolt mounting portion 74552 of the second adjusting block 7455, each of which is provided with an X-direction bolt 7458, each of which is threadedly connected to the vertical portion 74541 of the first adjusting block 7454, and a first rotating shaft 7493 is also connected between the vertical portion 74541 of the first adjusting block 7454 and the X-direction bolt mounting portion 74552 of the second adjusting block 7455.

[0067] The heating block 7456 is provided with a plurality of through holes, each of which is provided with a Y-direction bolt 7459, each of which is threadedly connected to the Y-direction bolt mounting portion 74553 of the second adjusting block 7455, and a second rotating shaft 7495 is further provided between the heating block 7456 and the Y-direction bolt mounting portion 74553 of the second adjusting block 7455. The heating block 7456 is provided with an extension portion, and a plurality of second-type top screws 7494 are provided on the extension portion of the heating block 7456, and the bottom end of the Y-direction bolt mounting portion 74553 of the second adjusting block 7455 is supported by the second-type top screw 7494. Specifically, the second-type top screw 7494 can pass through the extension portion of the hot pressing head 7457 and the heating block 7456 in sequence.

[0068] Specifically, when the hot pressing head 7457 needs to be leveled, the X-direction bolt 7458 can be loosened, and then the first type of top screw 7492 can be screwed to allow the second adjustment block 7455 to rotate around the first rotating shaft 7493, and the level can be adjusted by pressure-sensitive paper test to complete the θx level adjustment. After the adjustment is completed, the X-direction bolt 7458 is locked. Then the Y-direction bolt 7459 is loosened, and the second type of top screw 7494 is screwed to allow the heating block 7456 to rotate around the second rotating shaft 7495, and the level can be adjusted by pressure-sensitive paper test to complete the θy level adjustment. After the adjustment is completed, the Y-direction bolt 7459 is locked.

[0069] It should be noted that the above-mentioned through holes for the bolts to pass through can have larger gaps to facilitate the adjustment of the levelness.

[0070] Specifically, the heat insulation plate 7452 is used to prevent heat from being transferred to the second type longitudinal guide rail assembly 742, causing the second type longitudinal guide rail assembly 742 to deform and become stuck.

[0071] In one of the embodiments, based on the above, it further includes a bottom translation component 6, and the frame 2 is set on the bottom translation component 6.

[0072] The bottom translation assembly 6 is used to move the frame 2 horizontally, so that it is convenient to perform pressure-maintaining operations on multiple rows of products respectively.

[0073] Furthermore, the bottom translation assembly 6 includes a support plate 607, the frame 2 has two support legs 21, the two support legs 21 are connected to the support plate 607, the support plate 607 is installed on the transverse guide rail assembly 601, a transverse drive assembly 604 is arranged on the outer side of the support plate 607, the transverse drive assembly 604 is connected to the floating joint 603 arranged on the support plate 607, a block is also connected to one side of the support plate 607, hydraulic buffers 602 for limiting position are respectively arranged on both sides of the block, and a detection piece 606 is also arranged on the support plate 607, and the detection piece 606 is used to trigger the photoelectric sensor 605 arranged on the outer side of the support plate 607 to generate a signal.

[0074] Specifically, the lateral drive assembly 604 may be a cylinder or other drive mechanism. The lateral drive assembly 604 is used to drive the support plate 607 to move horizontally, and then drive the frame 2 to move horizontally through the support plate 607. The detection sheet 606 cooperates with the photoelectric sensor 605 to confirm whether the support plate 607 has moved into place.

[0075] The embodiment of the present application also provides a heating and pressure-maintaining method, which adopts the heating and pressure-maintaining mechanism, and specifically includes: first determining the pressure value required for product pressure maintenance, and determining the use of the counterweight component 744 and the weight-reducing component 5 according to the pressure value.

[0076] In one of the embodiments, the pressure value required for pressure maintenance is met by using the counterweight component 744 alone, the weight reduction component 5 alone, or the counterweight component 744 and the weight reduction component 5 in combination.

[0077] The above method of the present application can ensure that the pressure remains constant during the product pressure maintenance process, and can conveniently and flexibly adjust the required pressure value.
