Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, and in particular to a weight stacking type 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] In the existing actual operation, on the one hand, the pressurized heating devices used are basically provided with a workpiece pressure plate and a counter-top spring fixed on the upper part of the corresponding workpiece pressure plate, which provides elastic force to press down multiple small workpieces through the provided counter-top spring. The inventor of this patent found that the elastic force of the provided counter-top spring will gradually weaken over time, so it needs to be replaced every certain period of use. This increases maintenance costs and manpower. On the other hand, due to the different placement positions of the HAF glue, this leads to very subtle height differences between the upper end faces of the glue, which also leads to very subtle height differences between the upper end faces of the multiple small workpieces subsequently placed. As a result, when a pressurized heating device with a heating plate with a flat bottom surface is simply used to heat and pressurize them synchronously, the corresponding multiple small workpieces with lower upper end faces cannot be heated and pressurized well.

[0006] Moreover, for the utility model patent "Hot Melt Water Cooling Pressure Maintaining Equipment" disclosed with the above-mentioned patent number "202122640361.0", the support platform is floated by setting spring parts. Over time, the elastic force of the spring parts used will gradually decrease, so that the floating stroke of the support platform will also become smaller after a long time of use, making it unable to better support the camera module that needs to be heated and pressurized.

[0007] 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.

[0067] The following describes in detail a weight stacking high-precision heating and pressure-maintaining device 1000 according to an embodiment of the present invention with reference to the accompanying drawings.

[0068] Reference Figures 1 to 14 As shown, the weight stacking high-precision heating and pressurizing equipment 1000 provided according to an embodiment of the present invention includes a heating and pressurizing reverse-pressing fixture 10 for fixing a workpiece, a single-powered multiple-weight individual heating and pressurizing fixture 20 for pressing the workpiece downward by weights and capable of independently heating and pressurizing multiple positions of the workpiece, and a lifting member A (not shown) for controlling the vertical movement of the single-powered multiple-weight individual heating and pressurizing fixture 20;

[0069] The single-powered, multiple-weight, separate heating and pressure-maintaining jig 20 is fixedly mounted on the bottom of the lifting member A (not shown) and is located directly above the heating and pressure-maintaining reverse-top jig 10 .

[0070] Based on the above, it is clear that when this application is implemented, it is mainly used as a weight stacking 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.

[0071] 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 single-powered multiple-weight separate 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.

[0072] With regard to the above, it is clear that the single-powered multiple-weight individual heating and pressurizing jig 20 provided in the present application can heat and pressurize multiple fixed small workpieces separately by pressing the weights downward. Even if there is a very slight height difference, since the single-powered multiple-weight individual heating and pressurizing jig 20 provided in the present application obviously adopts the method of pressing the weights downward to heat and pressurize multiple fixed small workpieces separately, this enables the multiple small workpieces provided to be better heated and pressurized.

[0073] Moreover, since the single-powered multiple-weight individual heating and pressure-maintaining jig 20 provided in the present application heats and pressurizes multiple fixed small workpieces separately by pressing down the weights, when the present application adopts the method of pressing down the weights to replace the multiple top pressure springs 210 used traditionally to provide downward pressure, this also enables the downward pressure on multiple small workpieces to remain constant for a long time, making the present application more stable and reliable to use, and can greatly reduce replacement costs and maintenance costs.

[0074] At the same time, when the present application heats and pressurizes multiple fixed small workpieces separately by pressing down with weights, the multiple pieces of HAF glue corresponding to the bottom of the corresponding multiple small workpieces will be 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 heat pressing.

[0075] Therefore, through the above-mentioned optimized design, the single-power multiple-weight individual heating and pressure-maintaining fixture 20 of the present application is highly practical and has good use effect.

[0076] Furthermore, in specific implementation, Figure 2-Figure 7 As shown, according to one embodiment of the present invention, the single-power multiple-weight individual 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 heat-pressing columns 204 and a plurality of weight members 205;

[0077] 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 the lower ends thereof are provided with support blocks 2031 horizontally toward the center and lower part of the power plate 201; the workpiece pressure plate 202 is limited to be directly below the power plate 201 and is supported by the plurality of 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;

[0078] In addition, the power plate 201 is provided with a plurality of through grooves 2011 which pass through the upper and lower end surfaces thereof and correspond to the plurality of pressure holes 2021; the lower ends of the plurality of heat-pressurized columns 204 are correspondingly limited in the plurality of pressure holes 2021, and the upper ends of the plurality of heat-pressurized columns 204 are correspondingly limited in the plurality of through grooves 2011; and the plurality of weight components 205 are correspondingly detachably placed in the upper parts of the plurality of through grooves 2011.

[0079] Here, it should be noted that in actual operation, after the single-powered multiple-weight individual heating and pressure-maintaining jig 20 described in the present application descends to a certain height, the workpiece pressing plate 202 set 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 pieces of HAF glue fixed on the upper end face of the large workpiece will be located at the positions of the multiple pressure holes 2021. When the single-powered multiple-weight individual heating and pressure-maintaining jig 20 described in the present application continues to descend to a certain height, the bottoms of the multiple heat-pressurized columns 204 will naturally reach the upper end faces of the corresponding multiple small workpieces. At this time, the multiple weight components 205 are at the corresponding When placed on the upper part of the multiple through grooves 2011, the bottom thereof will naturally contact the top of the multiple heat-pressing columns 204, so as to apply downward pressure to the multiple heat-pressing columns 204 to prompt them to heat-press the corresponding multiple small workpieces. In this way, the multiple small workpieces can be heated and pressurized better, and the present application adopts multiple weight components 205 to replace the multiple top pressure springs 210 used in the traditional way to provide downward pressure, so that the downward pressure on the multiple small workpieces can be kept constant for a long time, making the present application more stable and reliable to use, and the quality of the multiple weight components 205 remains basically unchanged for a long time, so that the replacement cost and maintenance cost can be greatly reduced.

[0080] Furthermore, in the specific implementation, continue to compare Figure 2-Figure 7 As shown, according to one embodiment of the present invention, the single-power multiple-weight individual heating and pressure-maintaining fixture 20 further includes a plurality of pressure-relieving components 206;

[0081] Among them, reference Figure 7 As shown, the upper end surface of the power plate 201 is provided with pressure relief grooves 2012 on the sides of the plurality of through grooves 2011, referring to Figure 5 and Figure 6 As shown, the outer walls of the upper ends of the multiple heat-pressurized columns 204 are respectively provided with ears 2041 protruding outward and facing the pressure-relieving grooves 2012 at similar positions; the multiple pressure-relieving components 206 are correspondingly clamped in the multiple pressure-relieving grooves 2012, and their upper ends correspondingly contact the lower bottom surfaces of the multiple ears 2041.

[0082] It should be noted here that the above-mentioned multiple pressure-relief components 206 in this application all provide a certain buffering force, so that when the multiple weight components 205 are placed on the upper part of the multiple through grooves 2011 to apply downward pressure to the multiple hot pressurizing columns 204 to prompt them to hot press the corresponding multiple small workpieces, the multiple hot pressurizing columns 204 will not directly and rigidly heat and pressurize the corresponding multiple small workpieces, so that the corresponding multiple small workpieces are not easily crushed due to hard force, making this application more stable and reliable to use.

[0083] Preferably, in this embodiment, two pressure-relieving grooves 2012 are respectively provided on the upper end surface of the power plate 201 at the periphery of the plurality of through grooves 2011, facing downwardly and oppositely to each other, and two ears 2041 are respectively protruded outward on the outer walls of the upper ends of the plurality of heat-pressurized columns 204, facing the two pressure-relieving grooves 2012 at similar positions; a pressure-relieving component 206 is respectively mounted in each of the pressure-relieving grooves 2012, so that the stability of the pressure relief of the plurality of heat-pressurized columns 204 in the vertical direction can be better maintained.

[0084] And preferably, in this embodiment, each of the pressure relief components 206 is a spring pressure relief component, which is common in the prior art, so its details are not described in detail here.

[0085] Furthermore, in the specific implementation, Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, each of the weight components 205 includes a columnar reference weight 2051 and a plurality of detachable sheet-like tiny weight pieces 2052 stacked on top of the reference weight 2051;

[0086] Among them, the lower ends of the multiple reference weights 2051 are correspondingly inserted into the upper parts of the multiple through slots 2011, and their bottoms are correspondingly against the top surfaces of the multiple heat-pressurized columns 204; a fixing pin 20511 is vertically provided on the top of each of the reference weights 2051; and the multiple tiny weight pieces 2052 are respectively provided with fixing holes 20521 that pass through their upper and lower end surfaces and are suitable for the fixing pin 20511 to pass through.

[0087] Preferably, in this embodiment, the control Figures 2 to 5As shown, two fixing pins 20511 are vertically provided on the top of each reference weight 2051; and two fixing holes 20521 are respectively opened on the plurality of tiny weight pieces 2052 and pass through the upper and lower end surfaces thereof so as to allow the two fixing pins 20511 to pass through accordingly.

[0088] It should be noted here that when actually using this application, in order to pre-detach the multiple said tiny weight pieces 2052 and retain the multiple said reference weights 2051, so that they can be inserted into the upper part of the multiple said through grooves 2011 and their bottoms can be correspondingly against the tops of the multiple said hot pressurizing columns 204, when it is necessary to pressurize the corresponding multiple small workpieces later, according to actual needs, a suitable number of said tiny weight pieces 2052 can be stacked on the top of the said reference weights 2051 at different positions, so that when the present application uses multiple said weight components 205 to press down the multiple said hot pressurizing columns 204, the downward pressure can also be flexibly adjusted, so that the overall use effect of the single-powered multiple weights separate heating and pressure-maintaining fixture 20 of this application can be effectively improved.

[0089] Furthermore, by providing the fixing pins 20511 to fix the stacked plurality of tiny weight pieces 2052, the stacking stability of the plurality of tiny weight pieces 2052 is good and they will not slide when they are stacked and fixed to the top of any reference weight 2051, so that the plurality of weight components 205 have excellent stability in use.

[0090] In addition, in a specific implementation, according to one embodiment of the present invention, the single-power multiple-weight individual heating and pressure-maintaining jig 20 further includes a plurality of vertical guide rails 207 and a plurality of corresponding guide blocks 208 that can move up and down and are provided on the plurality of vertical slide rails 40;

[0091] The plurality of vertical guide rails 207 are vertically fixed on the upper end surface of the power plate 201 ; and the plurality of guide blocks 208 are correspondingly fixed on the outer walls of the plurality of reference weights 2051 .

[0092] It should be noted here that, since in actual use, the lengths of the multiple reference weights 2051 will be very long, and their placement stability will be poor when only their lower ends are placed on the upper parts of the multiple through slots 2011, the present application provides multiple vertical guide rails 207 and multiple corresponding guide blocks 208 that can move up and down on the multiple vertical guide rails 207 to fix the multiple reference weights 2051 accordingly, so that the placement stability of the multiple reference weights 2051 is effectively improved, and they can also move stably in the up and down directions, making them less likely to shake or tip over during use.

[0093] Furthermore, in this technical solution, according to one embodiment of the present invention, the single-power multiple-weight individual heating and pressure-maintaining jig 20 further includes a plurality of guide posts 209 and a plurality of pressure springs 210;

[0094] Among them, the workpiece pressure plate 202 is evenly opened on the periphery thereof with a plurality of guide holes 2022 penetrating its upper and lower end surfaces; a plurality of the guide columns 209 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 holes 2022; a plurality of the top pressure springs 210 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.

[0095] Initially, the workpiece pressing plate 202 is supported by the plurality of supporting blocks 2031 , and the plurality of pressing springs 210 are in a natural state or a compressed state.

[0096] From this, it can be clearly seen that after the single-powered multiple-weight individual 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 onto the fixed large workpiece to press and fix it. At this time, the multiple small workpieces corresponding to the upper surfaces of the multiple pieces of HAF glue 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 single-powered multiple-weight individual heating and pressure-maintaining fixture 20 described in the present application continues to descend to a certain height, when the bottoms of the multiple heat-pressurizing columns 204 correspond to the upper end faces of the multiple small workpieces set up, the multiple pressure springs 210 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.

[0097] Moreover, since the workpiece pressure plate 202 is evenly provided with a plurality of guide holes 2022 penetrating the upper and lower end surfaces thereof around its periphery, and a plurality of guide posts 209 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 holes 2022, therefore, in actual use of the present application, by setting the guide posts 209 for upward and downward guidance, the workpiece pressure plate 202 can be accurately displaced in the upward and downward directions and not easily displaced circumferentially, so that the single-powered multiple-weight separate heating and pressure-maintaining fixture 20 described in the present application is further improved in terms of stability and reliability.

[0098] Again, in a specific implementation, according to one embodiment of the present invention, the single-power multiple weights individual heating and pressure-maintaining fixture 20 of the present invention further includes a limit block 211 for correspondingly limiting the downward stroke of the multiple weight members 205;

[0099] The plurality of limit blocks 211 are horizontally fixed on the upper end surface of the power plate 201, and one end of each of the limit blocks 211 extends above the plurality of through slots 2011; the outer wall of the lower end of each of the reference weights 2051 of the plurality of weight members 205 is respectively provided with a limit slot 20512 suitable for inserting one end of the limit block 211 at the corresponding position;

[0100] Initially, there is a certain distance between the upper end surface of one end of each of the limiting blocks 211 and the inner top surface of the limiting groove 20512 at the corresponding position, and the corresponding multiple distances form corresponding maximum downward pressing strokes.

[0101] From this, it can be clearly seen that when multiple limit blocks 211 are provided in the present application to limit the downward stroke of multiple weight components 205, multiple small workpieces are well protected when they are pressed down accordingly, and human error will not cause a large number of tiny weight pieces 2052 to be stacked on top of a certain reference weight 2051, resulting in excessive downward pressure and crushing the small workpieces to be pressed down and fixed.

[0102] Furthermore, according to one embodiment of the present invention, the single-power multiple-weight individual heating and pressure-maintaining fixture 20 of the present invention further includes multiple pressure sensors A212;

[0103] Among them, the top surfaces of the multiple heat-pressurized columns 204 are respectively provided with grooves 2042 downwardly; the multiple pressure sensors A212 are correspondingly fixed in the multiple grooves 2042; the lower ends of the multiple reference weights 2051 correspondingly rest against the top surfaces of the multiple pressure sensors A212.

[0104] Therefore, by setting up multiple pressure sensors A212, the pressure intensity of multiple hot pressurizing columns 204 on multiple small workpieces can be detected accordingly, so that when the pressure of a certain hot pressurizing column 204 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.

[0105] Furthermore, through the above-mentioned optimized design, the use effect of the whole composed of the single-power multiple-weight individual heating and pressure-maintaining fixture 20 described in the present application can be further improved.

[0106] In addition, refer to Figures 8 to 14 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;

[0107] 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 having a downwardly protruding camera module, and the upper end surface of the heatable workpiece carrier plate 1011 is downwardly opened with a lifting opening 10111 facing the camera module.

[0108] Furthermore, the camera module floating heating support 102 is embedded in the lifting opening 10111 and fixed to the upper portion of the lifting member B103; the lifting member B103 is mounted on the fixed base plate 1013. When the workpiece is pressed against the upper end surface of the heatable workpiece support plate 1011, the camera module floating heating support 102 can rise until it elastically contacts the camera module.

[0109] 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 will be 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 set up 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.

[0110] From the above, it is clear that:

[0111] 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.

[0112] 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.

[0113] Furthermore, through the above-mentioned optimized design, the heating and pressure-maintaining reverse-top fixture 10 described in the present application is also highly practical, stable in use, and reliable in use.

[0114] It should be added that, in the specific implementation, Figure 12-14 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;

[0115] The heating block 1021, the heat insulating block 1022 and the lifting block 1023 are fixed 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 the left and right sides of the inner bottom surface of the U-shaped seat 1024 are respectively provided with guide grooves 10241 extending through the lower bottom surface thereof; two guide rods 10231 are provided on both sides of the bottom of the lifting block 1023 and extend downwardly and pass through the two guide grooves 10241 from top to bottom;

[0116] 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;

[0117] 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 .

[0118] 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:

[0119] On the one hand, the two guide holes 2022 can play a better guiding role to limit the two guide rods 10231 to move up and down only in the vertical direction, so that the heating block 1021 used to support the camera module has good lifting stability and good lifting flatness.

[0120] 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.

[0121] Furthermore, through the above-mentioned optimized design, the overall use effect of the heating and pressure-maintaining reverse-top fixture 10 described in the present application can be effectively improved.

[0122] It should be further added that, in a specific implementation, 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;

[0123] Among them, an upper slot 10232 is opened upward in the middle of the bottom of the lifting block 1023; a lower slot 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 fixed to the upper slot 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 fixed in the lower slot 10242.

[0124] 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:

[0125] 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.

[0126] Second point, when using the present 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 dynamic 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 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.

[0127] 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.

[0128] 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.

[0129] Furthermore, through the above-mentioned optimized design, the overall use effect of the heating and pressure-maintaining reverse-top fixture 10 described in the present application can be further improved.

[0130] Moreover, in the present technical solution, according to one embodiment of the present invention, the heating and pressure-maintaining counter-top jig 10 described in the present application further includes a plurality of clamping jaw members 104 for clamping and fixing the workpiece; the plurality of clamping jaw members 104 are evenly fixed on the periphery of the upper end surface of the heatable workpiece carrier plate 1011 .

[0131] Preferably, in this embodiment, the clamping jaws 104 include fixed clamping jaws 1041 fixed on two adjacent sides of the upper end surface of the heatable workpiece carrier plate 1011 and movable clamping jaws 1042 fixed on the other two adjacent sides of the upper end surface of the heatable workpiece carrier plate 1011;

[0132] Among them, the upper end surface of the fixed base plate 1013 is installed with two driving components 105 for correspondingly controlling the two movable clamps 1042 to move toward the position of the middle of the upper end surface of the heatable workpiece supporting plate 1011. The upper parts of the two driving components 105 are correspondingly connected to the two movable clamps 1042, and the two driving components 105 are preferably cylinder-driven linear modules or screw-driven linear modules.

[0133] Therefore, the present application clamps and fixes the workpiece through the two fixed clamping jaws 1041 and the two movable clamping jaws 1042, so that the fixed workpiece is not easily displaced in the circumferential direction.

[0134] It is further necessary to add that Figure 1 As shown, in a specific implementation, according to one embodiment of the present invention, the present application further includes a horizontal U-shaped bracket seat 30, a vertical slide rail 40 and a slider 50;

[0135] 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 on the vertical slide rail 40; the multi-position heating and pressure-maintaining jig is fixed on the slider 50; the lifting component A (not shown) is fixed on the top of the horizontal U-shaped bracket seat 30, and the single-power multiple-weight separate heating and pressure-maintaining jig 20 is fixed at its lower end. Specifically, its lower end is fixedly connected to the middle part of the upper end surface of the power plate 201.

[0136] Preferably, in this embodiment, a plurality of the vertical slide rails 40 and the sliders 50 are provided, and the plurality of 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 the plurality of sliders 50 are correspondingly arranged on the plurality of vertical slide rails 40 and can move up and down, and the plurality of sliders 50 are all connected to the bottom of the lifting component A (not shown).

[0137] For the above, we can summarize:

[0138] First, the present application uses the vertical slide rail 40 and the slider 50 to drive the multi-position heating and pressure-maintaining jig to move in the up and down directions, which can play a better guiding role, making the multi-position heating and pressure-maintaining jig more stable and reliable when moving in the up and down directions.

[0139] 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, the lifting component A (not shown), 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 It 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.

[0140] Furthermore, through the above-mentioned optimized design, the overall use effect of this application can be optimized.

[0141] Other embodiments and the like are not described here as examples.

[0142] To sum up, the weight stacking high-precision heating and pressurizing equipment 1000 provided by the present invention, when implemented, the overall structure of this application adopts a single-power multi-point heating and pressurizing method to heat and pressurize multiple small workpieces separately. Specifically, it adopts a weight pressing method to heat and pressurize multiple small workpieces separately, which makes the downward pressure on multiple small workpieces remain constant for a long time, making this application more stable and reliable to use, and can greatly reduce replacement costs and maintenance costs.

[0143] At the same time, when the present application heats and pressurizes multiple fixed small workpieces separately by pressing down with weights, the multiple pieces of HAF glue corresponding to the bottom of the corresponding multiple small workpieces will be evenly melted, 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 present application also has multiple corresponding pressure-relief components 206, which makes it difficult for the corresponding multiple small workpieces to be crushed due to hard force.

[0144] 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.

[0145] In addition, when the lifting component B103 drives the camera module floating heating support 1021 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.

[0146] Furthermore, as a whole, this application is indeed extremely practical and has excellent performance.
