Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, and in particular to a spring-loaded high-precision heating and pressure-maintaining equipment. Background Art

[0002] In the manufacturing process of various smart devices, such as smartphones, cameras, tablets, and smart bracelets, it is often necessary to fix two workpieces that constitute their structure together by smooth pressing with adhesive. For example, small parts such as the camera module and lighting of a smartphone need to be fixed to its back panel by smooth pressing with hot melt adhesive.

[0003] Conventionally, a pressure holding device is used when hot pressing and fixing two corresponding workpieces. Traditional pressure holding equipment, such as the utility model patent "Hot Melt Water Cooling Pressure Holding Equipment" disclosed in the patent number "202122640361.0" previously applied for by the applicant of this patent, basically sets a jig table to fix the large workpiece, and adheres multiple small workpieces to the upper surface of the corresponding large workpiece by applying hot melt adhesive, and a pressurizing and heating device with a heating plate with a flat lower surface is set above the corresponding jig table. When the corresponding pressurizing and heating device moves downward for a certain distance to press down the corresponding multiple small workpieces for a certain period of time and when the corresponding hot melt adhesive is melted, it can press and fix the corresponding large workpiece and the multiple small workpieces together.

[0004] Since the hot melt adhesive used is HAF adhesive, which is not sticky at room temperature and can only produce strong adhesion after being pressurized and heated, before pressing and fixing the corresponding large workpiece and multiple small workpieces, it is also necessary to use a heating pre-pressing mechanism to pre-melt the hot melt adhesive on the upper surface of the corresponding large workpiece to a certain degree, and then the corresponding multiple small workpieces can be attached thereon, and then the corresponding large workpiece and multiple small workpieces that are attached together can be pressed and fixed.

[0005] However, in the existing actual operation, due to the different installation positions of the HAF glue, there will be very slight height differences between the upper end surfaces of each other, so that the upper end surfaces of the multiple small workpieces installed subsequently will also have very slight height differences. As a result, when the workpiece pressing fixture head with a flat bottom surface of the heating plate is simply used to heat and pressurize them synchronously, the corresponding multiple small workpieces with lower upper end surface heights cannot be heated and pressurized well. Moreover, for the utility model patent "Hot Melt Water Cooling Pressure Holding Equipment" disclosed with the above-mentioned patent number "202122640361.0", the support platform is floated by setting a spring part. Over time, the elastic force of the spring part will gradually decrease, so that the floating stroke of the support platform will become smaller after a period of time, making it impossible to better support the camera module that needs to be heated and pressurized.

[0006] In this regard, the inventor of this patent combined his actual work experience, thought about the problems encountered in his work, read a large amount of scientific research materials and literature, and searched the website of the State Intellectual Property Office for novelties, and gradually conceived and designed this application to solve relevant technical problems.

Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0063] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components.

[0065] The following describes in detail a spring-loaded high-precision heating and pressure-maintaining device 1000 according to an embodiment of the present invention with reference to the accompanying drawings.

[0066] Reference Figures 1 to 13As shown, the spring-pressing high-precision heating and pressure-maintaining equipment 1000 provided according to an embodiment of the present invention includes a heating and pressure-maintaining reverse-pressing fixture 10 for fixing a workpiece, a multi-position heating and pressure-maintaining fixture 20 for pressing the workpiece downward by spring force and capable of independently heating and pressurizing multiple positions of the workpiece, and a lifting member A30 for controlling the up and down movement of the multi-position heating and pressure-maintaining fixture 20;

[0067] The multi-position heating and pressure-maintaining jig 20 is fixed at the bottom of the lifting component A30 and is located directly above the heating and pressure-maintaining reverse-top jig 10 .

[0068] Based on the above, it is clear that when this application is implemented, it is mainly used as a spring-top pressure-type high-precision heating and pressure-maintaining equipment 1000 for heating and pressurizing multiple small workpieces corresponding to the upper surfaces of multiple pieces of HAF glue adhered to the upper end surface of a large workpiece.

[0069] Specifically, when applying the present application, the present application is assembled according to the structure described above, and the heating and pressure-maintaining anti-top fixture 10 described in the present application is used to fix a large workpiece (such as the back panel of a mobile phone, etc.), and then, a piece of HAF glue is respectively affixed to multiple preset positions on the upper end surface of the fixed large workpiece. Subsequently, a heating and pre-pressing mechanism is used to pre-melt the corresponding multiple pieces of HAF glue to a certain degree, and then, multiple other small workpieces (such as collection cameras and lighting lamps, etc.) are affixed to the upper surface of the multiple corresponding pieces of HAF glue. Finally, the multi-position heating and pressure-maintaining fixture 20 described in the present application can be used to press and fix the corresponding large workpiece and multiple small workpieces that are bonded together.

[0070] With regard to the above, it is clear that the multi-position heating and pressure-maintaining jig 20 provided in the present application can perform spring-type heating and pressurizing on multiple fixed small workpieces separately, even if they have very slight height differences. However, since the multi-position heating and pressure-maintaining jig 20 provided in the present application obviously adopts a spring-type top-pressure method to heat and pressurize multiple fixed small workpieces separately, this enables the multiple small workpieces provided to be better heated and pressurized.

[0071] Moreover, since the multi-position heating and pressure-maintaining fixture 20 provided in the present application adopts a spring-pressing method to perform spring-pressing heating and pressurizing on multiple fixed small workpieces separately, this also makes it difficult for the multiple fixed small workpieces to be crushed by force.

[0072] Furthermore, it can be concluded that, through the above-mentioned optimized design, the overall structure of the present application adopts a single-power multi-point heating and pressurizing method to perform elastic heating and pressurization on multiple small workpieces separately, so that the multiple pieces of HAF glue corresponding to the bottom of the corresponding multiple small workpieces will be heat-melted evenly, so that a better heat-melting effect can be achieved quickly, so that the multiple corresponding small workpieces can be well fixed by hot pressing, and the corresponding multiple small workpieces are not easily crushed due to hard force. Therefore, the present application is highly practical and has good use effect.

[0073] Furthermore, in specific implementation, Figure 2-Figure 5 As shown, according to one embodiment of the present invention, the multi-position heating and pressure-maintaining fixture 20 includes a power plate 201, a workpiece pressure plate 202, a pressure plate supporting member 203, a plurality of top pressure springs A204 and a plurality of heat-pressing columns 205 for pressing a part of the workpiece;

[0074] The pressure plate supporting members 203 are provided in plurality and are evenly fixed downwardly on the outer periphery of the power plate 201, and a support block 2031 is provided horizontally at the lower end of each of the support members 2031 toward the center and bottom of the power plate 201; the workpiece pressure plate 202 is positioned directly below the power plate 201 and is supported by the support blocks 2031, and the workpiece pressure plate 202 is provided with a plurality of pressure holes 2021 penetrating the upper and lower end surfaces thereof;

[0075] In addition, the lower bottom surface of the power plate 201 is provided with a plurality of fixing grooves 2011 corresponding to the plurality of pressure holes 2021; a plurality of the top pressure springs A204 are vertically mounted in the plurality of fixing grooves 2011, and a plurality of the hot pressurizing columns 205 are fixed at their lower ends; the plurality of the hot pressurizing columns 205 are correspondingly limited in the plurality of pressure holes 2021, and can move up and down along the plurality of pressure holes 2021.

[0076] From the above, we can understand that:

[0077] First, the multi-position heating and pressure-keeping jig 20 described in the present application is provided with the workpiece pressing plate 202. After the multi-position heating and pressure-keeping jig 20 described in the present application is lowered to a certain height, the workpiece pressing plate 202 can be naturally pressed on the fixed large workpiece to press and fix it. At this time, the multiple small workpieces corresponding to the upper surfaces of the multiple HAF glues fixed on the upper end face of the large workpiece will be located correspondingly at the positions of the multiple pressing holes 2021. The multi-position heating and pressure-keeping jig 20 described in the present application continues to descend to a certain height so that the bottom of a certain heat-pressing column 205 can reach the upper end face of the small workpiece with the lowest upper end face height, and the bottoms of the other multiple heat-pressing columns 205 can also reach the upper end faces of the small workpieces set at other positions. In this way, the multiple small workpieces set can all be heated and pressurized better.

[0078] Secondly, since the multiple heat-pressurized columns 205 are interference-fitted and can move up and down in the multiple pressure holes 2021, after the multiple heat-pressurized columns 205 are heated, they can directly heat and pressurize the multiple small workpieces, and the multiple corresponding small workpieces can transfer the heat to the HAF glue set at the bottom thereof. That is to say, in this application, each piece of HAF glue is also heated and pressurized separately, so that the multiple pieces of HAF glue can indeed quickly achieve a better hot melting effect, so that the multiple corresponding small workpieces can be well fixed by hot pressing.

[0079] Third, since the present application is provided with a plurality of the said top pressure springs A204, which are correspondingly connected to the upper parts of the plurality of said heat-pressurizing columns 205, the plurality of said heat-pressurizing columns 205 will not rigidly heat and pressurize the corresponding plurality of small workpieces, so that the corresponding plurality of small workpieces are not easily crushed due to hard force, making the present application stable and reliable to use.

[0080] Furthermore, in a specific implementation, according to one embodiment of the present invention, the multi-position heating and pressure-maintaining fixture 20 further includes a plurality of guide pillars 206 and a plurality of pressing springs B207;

[0081] Among them, the workpiece pressure plate 202 is evenly opened on the periphery thereof with a plurality of guide grooves 2022 penetrating the upper and lower end surfaces; a plurality of the guide columns 206 are evenly fixed downward on the periphery of the lower bottom surface of the power plate 201, and their lower ends are interference fit and movably passed through the plurality of the guide grooves 2022; a plurality of the top pressure springs B207 are evenly fixed between the periphery of the lower bottom surface of the power plate 201 and the periphery of the upper end surface of the workpiece pressure plate 202.

[0082] Initially, the workpiece pressing plate 202 is supported by the plurality of supporting blocks 2031 , and the plurality of pressing springs B207 are in a natural state or a compressed state.

[0083] From this, it can be clearly seen that after the multi-position heating and pressure-maintaining fixture 20 described in the present application descends to a certain height, the workpiece pressing plate 202 set up will naturally be pressed on the fixed large workpiece to press and fix it. At this time, the multiple small workpieces corresponding to the upper surfaces of the multiple HAF glues fixed on the upper end face of the large workpiece will be located correspondingly at the positions of the multiple pressing holes 2021. When the multi-position heating and pressure-maintaining fixture 20 described in the present application continues to descend to a certain height, when the bottoms of the multiple hot pressurizing columns 205 correspond to the upper end faces of the multiple small workpieces set up, the multiple pressure springs B207 set up will be compressed to provide a reverse force to push down the workpiece pressing plate 202, so that the workpiece pressing plate 202 can apply a certain downward pressure to press the fixed large workpiece.

[0084] Moreover, since the workpiece pressure plate 202 is evenly provided with a plurality of guide grooves 2022 penetrating the upper and lower end surfaces thereof around its periphery; and a plurality of guide posts 206 are evenly fixed downwardly on the periphery of the lower bottom surface of the power plate 201, and their lower ends are interference fit and movably passed through the plurality of guide grooves 2022, therefore, when the present application is actually used, by providing the guide posts 206 for upward and downward guidance, the workpiece pressure plate 202 can be accurately displaced in the upward and downward directions and is not easily displaced circumferentially, making the present application more stable and reliable to use.

[0085] Furthermore, in the specific implementation, continue to compare Figure 2-Figure 5 As shown, according to one embodiment of the present invention, the multi-position heating and pressure-maintaining fixture 20 further includes a detachable plate 208 for maintaining the elastic force of the plurality of pressing springs A204;

[0086] Among them, the removable plate 208 is fixedly mounted on the lower surface of the workpiece pressure plate 202 to block the multiple pressure holes 2021 and support the multiple hot pressurizing columns 205, and its periphery is removably fixed to the workpiece pressure plate 202 and / or the multiple support blocks 2031 by fastening bolts 209.

[0087] It should be noted here that, in specific implementation, before the use of this application, the lower ends of the multiple pressure springs A204 are fixed with the multiple heat-pressurized columns 205, and the multiple heat-pressurized columns 205 have a certain weight, which will correspondingly stretch the multiple pressure springs A204, so that the elastic force of the multiple pressure springs A204 will slowly decrease after a long time of use. Therefore, the multi-position heating and pressure-maintaining fixture 20 described in this application is provided with the removable plate 208 so that it is stacked and fixed at the bottom of the workpiece pressure plate 202. At this time, it can block the multiple pressure holes 2021 and support the multiple heat-pressurized columns 205, so that the multiple pressure springs A204 will not be stretched when not in use, so that their elasticity can be better maintained to increase their service life. Only when using this application, the fastening bolts 209 can be screwed to remove the removable plate 208.

[0088] From the above, it can be clearly seen that the multi-position heating and pressure-maintaining fixture 20 described in the present application can better protect the multiple pressure springs A204 by setting the removable plate 208, and can better maintain its elasticity to increase its service life, and can also protect the multiple heat-pressurizing columns 205 so that they are not damaged by foreign objects when not in use.

[0089] Furthermore, through the above-mentioned optimized design, the overall use effect of this application can be effectively improved.

[0090] In addition, in the specific implementation, still refer to Figure 2-Figure 5As shown, according to one embodiment of the present invention, the multi-position heating and pressure-maintaining fixture 20 further includes a plurality of detachable seats 210, a plurality of fixing blocks 211 and a plurality of pressure sensors A212;

[0091] Among them, multiple fixed grooves 2011 all penetrate to the upper end surface of the power plate 201, multiple detachable seats 210 are correspondingly detachably fixed in the multiple fixed grooves 2011, and the bottoms of the multiple detachable seats 210 are respectively upwardly opened with a accommodating groove 2101; multiple fixed blocks 211 are correspondingly fixed between the upper ends of the multiple pressure springs A204 and the bottoms of the multiple pressure sensors A212; multiple pressure sensors A212 are correspondingly fixed in the multiple accommodating grooves 2101.

[0092] Therefore, by setting up multiple pressure sensors A212, the pressure intensity of multiple hot pressurizing columns 205 on multiple small workpieces can be detected accordingly, so that when the pressure of a certain hot pressurizing column 205 on a certain small workpiece is too large or too small, it can be monitored in real time, so that the operator can make timely adjustments.

[0093] Furthermore, in this technical solution, Figure 6-Figure 12 As shown, according to one embodiment of the present invention, the heating and pressure-maintaining reverse top fixture 10 includes a fixture base 101, a camera module floating heating support 102 and a lifting component B103;

[0094] The fixture base 101 includes a heatable workpiece carrier plate 1011 and a fixed base plate 1013 that supports the heatable workpiece carrier plate 1011 via a plurality of support columns 1012. The heatable workpiece carrier plate 1011 is suitable for carrying a workpiece, and the workpiece has a downwardly protruding camera module. The upper end surface of the heatable workpiece carrier plate 1011 has a downwardly opening 10111 facing the camera module.

[0095] In addition, the camera module floating heating support 102 is embedded in the lifting port 10111 and fixed on the upper part of the lifting component B103, so as to be driven to float in the up and down directions through the lifting component B103; the lifting component B103 is installed on the fixed base plate 1013; when the workpiece is pressed against the upper end surface of the workpiece supporting plate, the camera module floating heating support 102 can rise to elastically offset the camera module.

[0096] When the heating and pressure-maintaining counter-top fixture 10 described in the present application is actually used, the camera module floating heating support 102 is driven to the lowest position in advance by the lifting component B103, and then the workpiece (such as the back panel of a smartphone) and the camera module to be pressed and fixed therewith are fixed on the upper end surface of the heatable workpiece carrier plate 1011, so that the camera module to be fixed is clamped and limited in the lifting port 10111. At this time, a layer of HAF glue block is pre-set between the camera module to be fixed and the corresponding workpiece (such as the back panel of a smartphone). Subsequently, the camera module floating heating support 102 is driven to rise to a certain height by the lifting component B103 until it is against the lower bottom surface of the camera module to be fixed. Finally, the multi-position heating and pressure-maintaining fixture 20 set in the present application is driven to descend a certain stroke, which can hot-press and fix the workpiece (such as the back panel of a smartphone) and the camera module to be pressed and fixed therewith.

[0097] From the above, it is clear that:

[0098] First, the present application is provided with the lifting component B103 to drive the camera module floating heating support 102 to rise and fall, so that compared with the traditional method as described in the background technology of the present application, which only uses spring parts to cause the camera module floating heating support 102 to float in the up and down directions, the present application does not have the problem of the elastic force gradually decreasing and causing the floating stroke to decrease. In other words, the present application can control the lifting position of the camera module floating heating support 102 more accurately, so that it can be used for a long time and can basically support the corresponding camera module well, so that the final hot pressing fixation effect between it and the workpiece (such as the back panel of a smartphone) is better.

[0099] Secondly, the heatable workpiece carrier plate 1011 and the camera module floating heating support 102 described in this application obviously have a heating function, so that after heating, they can conduct heat upward to the attached HAF glue block to achieve further rapid thermal melting, so that the corresponding camera module and other components and the workpiece (such as the back panel of a smartphone) can be further quickly hot-pressed and fixed to each other.

[0100] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is more practical, more stable in use and more reliable in use.

[0101] Again, in the specific implementation, continue to compare Figure 6-Figure 12 As shown, according to one embodiment of the present invention, the camera module floating heating support 102 includes a heating block 1021, a heat insulating block 1022, a lifting block 1023, a U-shaped seat 1024, a fixing ring 1025 and a floating limit pin 1026;

[0102] The heating block 1021, the heat insulating block 1022 and the lifting block 1023 are fixed together in sequence from top to bottom; the U-shaped seat 1024 is fixed to the lower bottom surface of the heatable workpiece carrier plate 1011 and faces the lifting opening 10111, and a guide hole 10241 is respectively formed on the left and right sides of the inner bottom surface of the U-shaped seat 1024 and extends through the lower bottom surface thereof; two guide rods 10231 extend downwardly from both sides of the bottom of the lifting block 1023 and are correspondingly interference fit through the two guide holes 10241 from top to bottom;

[0103] Furthermore, the fixing ring 1025 is fixed on the top of the lifting member B103; the floating limit pin 1026 passes through the fixing ring 1025, and its left and right ends are fixed between the lower ends of the two guide rods 10231; the inner diameter of the fixing ring 1025 in the vertical direction is larger than the outer diameter of the floating limit pin 1026 in the vertical direction;

[0104] Initially, the lower bottom surface of the floating limit pin 1026 fits against the inner lower wall of the fixing ring 1025 , and a lifting gap is formed between the inner top wall of the fixing ring 1025 and the upper top surface of the floating limit pin 1026 .

[0105] Therefore, by providing the camera module floating heating support 102 having the above-mentioned structure of the heating block 1021, the heat insulating block 1022, the lifting block 1023, the U-shaped seat 1024, the fixing ring 1025 and the floating limit pin 1026, it can be concluded that:

[0106] On the one hand, the two guide holes 10241 can play a better guiding role to limit the two guide rods 10231 to move only up and down in the vertical direction, so that the heating block 1021 used to support the camera module has good lifting stability and good lifting flatness.

[0107] On the other hand, by setting the fixed ring 1025 and the floating limit pin 1026, and limiting them to the initial state, a lifting gap is formed between the inner top wall of the fixed ring 1025 and the upper top surface of the floating limit pin 1026, which limits the lifting range of the heating block 1021 used to support the camera module, so that the lifting component B103 will not drive the heating block 1021 to rise too much due to misoperation, resulting in damage to the camera module to be supported.

[0108] Furthermore, through the above-mentioned optimized design, the overall use effect of the present application can be further improved.

[0109] It should be added that in the specific implementation, Figure 6-Figure 12 As shown, especially the control Figure 11 and Figure 12As shown, according to one embodiment of the present invention, the camera module floating heating support 102 further includes a reverse spring 1027, a connecting block 1028 and a pressure sensor B1029;

[0110] Among them, an upper clamping groove 10232 is opened upward in the middle of the bottom of the lifting block 1023; a lower clamping groove 10242 is opened downward in the middle of the inner bottom surface of the U-shaped seat 1024; the upper end of the anti-top spring 1027 is clamped to the upper clamping groove 10232, and the lower end is connected to the upper end surface of the connecting block 1028; the lower bottom surface of the connecting block 1028 is fixed to the upper part of the pressure sensor B1029, and the lower part of the pressure sensor B1029 is clamped and fixed in the lower clamping groove 10242.

[0111] Therefore, when the camera module floating heating support 102 of the present application further includes the anti-top spring 1027, the connecting block 1028 and the pressure sensor B 1029, the following effects can be achieved:

[0112] First, at the beginning, that is, when the present application is not in use, the lifting component B103 drives the camera module floating heating support 102 to rise to the highest position. At this time, the heating block 1021 of the camera module floating heating support 102 will be basically flush with the upper part of the lifting port 10111, and it will basically not give the anti-top spring 1027 downward pressure, so that the anti-top spring 1027 will be in a natural state, and it will not be in a compressed state for a long time, causing its elastic force to gradually decrease after a long time of use. That is to say, the present application sets the lifting component B103 to cooperate with the anti-top spring 1027 for use, so that the anti-top spring 1027 is basically not subject to downward pressure when not in use, so as to extend its service life.

[0113] Second point, when using this application, first drive the camera module floating heating support 102 to the lowest position through the lifting component B103, and then fix the workpiece (such as the back panel of a smart phone) and the camera module to be pressed and fixed thereto on the upper end surface of the heatable workpiece carrier plate 1011, so that the camera module to be fixed is clamped and limited in the lifting port 10111. At this time, a layer of HAF glue block will be pre-set between the camera module to be fixed and the corresponding workpiece (such as the back panel of a smart phone). Subsequently, the camera module is driven to float by the lifting component B103. The heating support 102 rises to a certain height until it contacts the lower bottom surface of the camera module to be fixed. Finally, the multi-position heating and pressure-maintaining fixture 20 provided in the present application is driven to descend a certain stroke, which can hot-press and fix the workpiece (such as the back panel of a smart phone) and the camera module to be pressed and fixed thereto together. During this hot-pressing and fixing process, the anti-top spring 1027 is in a compressed state, which will generate an upward reaction force to push up the lower bottom surface of the camera module to be fixed, so that the upper and lower sides of the camera module to be fixed are both hot-pressed and fixed, and the camera module to be fixed is fixed more firmly.

[0114] Third, when the lifting component B103 drives the camera module floating heating support 102 to rise to a certain height until it is against the lower bottom surface of the camera module to be fixed, the heating block 1021 of the camera module floating heating support 102 does not hard press upward against the lower bottom surface of the camera module to be fixed, but is buffered by the anti-top spring 1027, so that the camera module to be fixed is not easily damaged all at once, making the reliability of the application better.

[0115] Fourthly, by setting the pressure sensor B1029, the pressure strength of the camera module floating heating support 102 on the bottom surface of the camera module to be fixed can be detected, so that when the corresponding pressure is too large or too small, it can be monitored in real time, so that the operator can make timely adjustments.

[0116] Furthermore, through the above-mentioned optimized design, the overall use effect of the present application can be further improved.

[0117] It should be further added that, in specific implementation, according to one embodiment of the present invention, the present application also includes a plurality of clamping jaw members 108 for clamping and fixing the workpiece; the plurality of said clamping jaw members 108 are evenly fixed on the periphery of the upper end surface of the heatable workpiece carrier plate 1011 .

[0118] Preferably, in a specific implementation, according to one embodiment of the present invention, the clamping member 108 includes fixed clamping jaws 1081 fixed on two adjacent sides of the upper end surface of the heatable workpiece carrier plate 1011 and movable clamping jaws 1082 fixed on the other two adjacent sides of the upper end surface of the heatable workpiece carrier plate 1011;

[0119] Among them, the upper end surface of the fixed base plate 1013 is installed with two driving components 109 for correspondingly controlling the two movable clamps 1082 to move toward the position of the middle part of the upper end surface of the heatable workpiece carrier plate 1011. The upper parts of the two driving components 109 are correspondingly connected to the two movable clamps 1082, and the two driving components 109 are preferably cylinder-driven linear modules or screw-driven linear modules.

[0120] Therefore, the present application clamps and fixes the workpiece through the two fixed clamping jaws 1081 and the two movable clamping jaws 1082, so that the fixed workpiece is not easily displaced in the circumferential direction.

[0121] It is further necessary to add that, Figure 6-Figure 12 As shown, in a specific implementation, according to one embodiment of the present invention, the heating and pressure-maintaining reverse ejection fixture 10 further includes a plurality of demoulding ejector pins 104, a lifting platform 105, a lifting component C106 and a pressure-relieving component 107;

[0122] A plurality of lifting holes 10112 extending through to the lower surface of the heatable workpiece carrier plate 1011 are evenly opened in the middle of the upper end surface; a plurality of demoulding ejector rods 104 are correspondingly arranged in the plurality of lifting holes 10112, and their upper ends are correspondingly located in the plurality of lifting holes 10112, and their lower ends are all extended downward to the outside of the lower part of the plurality of lifting holes 10112, and are all fixed to the upper end surface of the lifting platform 105; the pressure relief component 107 is connected between the lifting platform 105 and the lifting component C106, and the pressure relief component is preferably a spring pressure relief component; the lifting component C106 is installed on the fixed base plate 1013.

[0123] From this, it can be clearly seen that after the corresponding camera modules and other components and the workpiece (such as the back panel of a smart phone) are fixed to each other by hot pressing, the two driving components 109 correspondingly drive the two movable clamps 1082 to move a certain distance toward the position where the middle of the upper end surface of the heatable workpiece carrier plate 1011 is located, and then, the lifting component C106 drives the multiple demolding rods 104 to rise, and the tops of the multiple demolding rods 104 will extend out of the upper part of the multiple lifting holes 10112, and lift up the corresponding camera modules and other components and the workpiece (such as the back panel of a smart phone) that are fixed together by hot pressing. In this way, the unloading and transfer of the whole composed of the corresponding camera modules and other components and the workpiece (such as the back panel of a smart phone) is facilitated.

[0124] In addition, by arranging the pressure-relief member 107 to buffer the pressure, the plurality of demoulding ejector pins 104 are driven to rise by the lifting member C106 so that their tops extend correspondingly outside the upper parts of the plurality of lifting holes 10112 to lift the whole composed of the corresponding camera modules and other components and the workpiece (such as the back panel of a smart phone) that are fixed together by heat pressing. The tops of the plurality of demoulding ejector pins 104 do not rigidly lift the whole composed of the corresponding camera modules and other components and the workpiece (such as the back panel of a smart phone) that are fixed together by heat pressing, so that the whole composed of the corresponding camera modules and other components and the workpiece (such as the back panel of a smart phone) that are fixed together by heat pressing is not easily damaged at once, so that the reliability of the use of this application is optimal.

[0125] It should also be added that, in the specific implementation, Figure 1 and Figure 13 As shown, according to one embodiment of the present invention, the present application further comprises a horizontal U-shaped bracket seat 30, a vertical slide rail 40 and a slider 50;

[0126] Among them, the heating and pressure-maintaining counter-top jig 10 is installed on the inner bottom surface of the horizontal U-shaped bracket seat 30; the vertical slide rail 40 is fixed on the inner rear wall of the horizontal U-shaped bracket seat 30; the slider 50 can move up and down and is arranged on the vertical slide rail 40; the multi-position heating and pressure-maintaining jig 20 is fixed on the slider 50; the lifting component A30 is fixed on the top of the horizontal U-shaped bracket seat 30.

[0127] Preferably, in this embodiment, there are multiple vertical slide rails 40 and multiple sliders 50, and multiple vertical slide rails 40 are evenly fixed on the inner rear wall of the horizontal U-shaped bracket seat 30 from left to right, and multiple sliders 50 are correspondingly arranged on the multiple vertical slide rails 40 and can move up and down, and multiple sliders 50 are all connected to the bottom of the lifting component A30.

[0128] For the above, we can summarize:

[0129] First, the present application uses the vertical slide rail 40 and the slider 50 to drive the multi-position heating and pressure-maintaining jig 20 to move in the up and down directions, which can play a better guiding role, making the multi-position heating and pressure-maintaining jig 20 more stable and reliable when moving in the up and down directions.

[0130] Second, the present application sets the horizontal U-shaped bracket 30 to fix the designed heating and pressure-maintaining counter-top fixture 10, the multi-position heating and pressure-maintaining fixture 20, the lifting component A30, the vertical slide rail 40 and the slider 50, so that the overall structure of the present application is very compact and very stable. Figure 1 and Figure 13It can be seen that the horizontal U-shaped bracket seat 30 provided in the present application is an integrally formed structure during mold design, and it does not have any splicing structure, making it very stable to use, so that the entire pressure-maintaining equipment constituted by the present application is also more stable and reliable to use.

[0131] Furthermore, through the above-mentioned optimized design, the overall use effect of this application can be optimized.

[0132] Other embodiments and the like are not described here as examples.

[0133] To sum up, the spring top pressure high-precision heating and pressure-maintaining equipment 1000 provided by the present invention, in specific implementation, the overall structure of the present application adopts a single-power multi-point heating and pressurizing method to heat and pressurize multiple small workpieces separately, so that the multiple pieces of HAF glue corresponding to the bottom of the corresponding multiple small workpieces will be hot-melted evenly, so that a better hot-melt effect can be achieved quickly, so that the multiple corresponding small workpieces can be well fixed by hot pressing, and the corresponding multiple small workpieces are not easily crushed due to hard force.

[0134] In addition, the present application is provided with the lifting component B103 to drive the camera module floating heating support 102 to rise and fall, so that compared with the traditional method as described in the background technology of the present application that only uses spring parts to cause the camera module floating heating support 102 to float in the up and down directions, the present application does not have the problem of the elastic force gradually decreasing and causing the floating stroke to decrease. In other words, the present application can control the lifting position of the camera module floating heating support 102 more accurately, so that it can be used for a long time and can basically support the corresponding camera module better, so that it can finally be fixed to the workpiece (such as the back panel of a smartphone) by hot pressing with a better effect.

[0135] At the same time, when the lifting component B103 drives the camera module floating heating support 102 to rise to a certain height until it is against the lower bottom surface of the camera module to be fixed, the heating block 1021 of the camera module floating heating support 102 does not hard press upward against the lower bottom surface of the camera module to be fixed, but is buffered by the anti-top spring 1027, so that the camera module to be fixed is not easily damaged all at once, making the reliability of the application better.

[0136] Furthermore, as a whole, this application is indeed extremely practical and has excellent performance.
