Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a heating, pressure-holding, and reverse-top fixture. Background Technology

[0002] In the manufacturing process of various smart devices, such as smartphones, cameras, tablets and smart bracelets, it is often necessary to flatly press and fix two parts that make up the structure together with adhesive. For example, it is necessary to flatly press and fix small parts such as cameras and lights that make up smart devices to their back panels with hot melt adhesive.

[0003] In conventional methods for pressing and fixing two workpieces together, a fixture is typically used to hold the larger workpiece in place. Several smaller workpieces are then bonded to the surface of the larger workpiece using hot melt adhesive. A workpiece pressing fixture head is positioned above the fixture. As the workpiece pressing fixture head moves downwards for a certain distance, it presses down on the smaller workpieces for a certain duration. When the hot melt adhesive melts, the larger workpiece and the smaller workpieces are pressed and fixed together.

[0004] In the prior art, many smartphones typically have a camera module that protrudes from the rear end of their back panel. In order to fix the back panel of a smartphone with a camera module that protrudes from its rear end on a fixture table, the upper surface of the fixture table is usually opened downwards, and a support is set in the corresponding opening to support the corresponding camera module, so that it can be heat-pressed and fixed to the corresponding back panel by the workpiece pressing down the fixture head for a certain stroke.

[0005] Upon investigation, it was found that in actual operation, for traditional pressure-holding devices, such as the utility model patent "Hot Melt Pressure Holding Device" disclosed in the applicant's patent number "202122640150.7", the support platform is set up to float by setting up spring components. Over time, the elasticity of the spring components will gradually decrease, so that the floating stroke of the support platform will decrease after a long period of use, making it unable to properly support the corresponding camera module.

[0006] In response, the inventor of this patent, drawing on practical work experience, reflected on the problems encountered in his work, reviewed a large amount of scientific research data and literature, and conducted a novelty search through the website of the State Intellectual Property Office, gradually conceived and designed this application to solve the relevant technical problems. Summary of the Invention

[0007] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to provide a heating, pressure-holding, and reverse-topping fixture.

[0008] To achieve the above objectives, a heating and pressure-holding reverse-top fixture according to an embodiment of the present invention is suitable for placing a mobile phone back panel, wherein the mobile phone back panel has a downwardly protruding camera module, and includes a fixture base, a floating heating support for the camera module, and a lifting component A;

[0010] The floating heating support for the camera module is embedded in the lifting port and fixed on the upper part of the lifting component A, so that it can float in the vertical direction by being driven by the lifting component A; when the back panel of the mobile phone is pressed against the upper surface of the workpiece bearing plate, the floating heating support for the camera module can rise to elastically resist the camera module.

[0011] In addition, the heating, pressure-holding, and anti-jacking fixture according to the above embodiments of the present invention may also have the following additional technical features:

[0018] According to one embodiment of the present invention, the floating heating platform for the camera module further includes a U-shaped seat, a fixing ring, and a floating limiting pin;

[0019] The U-shaped seat is fixed to the bottom surface of the base plate and faces the lifting port. The bottom surface of the U-shaped seat has a guide hole on the left and right sides that extends through to its bottom surface. The bottom sides of the lifting block have two guide posts that are corresponding to the two guide holes and are interference fit from top to bottom.

[0020] The fixed ring is fixed to the top of the lifting component A; the floating limiting pin passes through the fixed ring, and its left and right ends are fixed between the lower ends of the two guide columns; the inner diameter of the fixed ring in the vertical direction is larger than the outer diameter of the floating limiting pin in the vertical direction.

[0021] Initially, the bottom surface of the floating limit pin is in contact with the lower inner wall of the fixed ring, and a lifting gap is formed between the top inner wall of the fixed ring and the top surface of the floating limit pin.

[0022] According to one embodiment of the present invention, the floating heating platform for the camera module further includes a counter-rotating spring, a connecting block, and a pressure sensor;

[0023] The lifting block has an upper slot at the bottom center; the U-shaped seat has a lower slot at the bottom center; the upper end of the anti-top spring is fixed to the upper slot, and the lower end is connected to the upper end face of the connecting block; the lower bottom surface of the connecting block is fixed to the upper part of the pressure sensor, and the lower part of the pressure sensor is fixed in the lower slot.

[0024] According to one embodiment of the present invention, the fixture base further includes a fixed base plate and a plurality of support columns for supporting the base plate;

[0025] Multiple support columns are correspondingly fixed between the periphery of the upper surface of the fixed base plate and the periphery of the lower surface of the base plate; the lifting component A is fixed to the upper surface of the fixed base plate.

[0026] According to one embodiment of the present invention, it further includes a plurality of gripper components for clamping and fixing the back panel of the mobile phone; the plurality of gripper components are uniformly fixed to the periphery of the upper surface of the heatable workpiece support plate.

[0027] According to one embodiment of the present invention, the gripper component includes fixed grippers fixed on adjacent sides of the upper end face of the heatable workpiece support plate and movable grippers fixed on other adjacent sides of the upper end face of the heatable workpiece support plate.

[0028] The upper surface of the fixed base plate is equipped with two driving components for correspondingly controlling the movement of the two movable grippers toward the center of the upper surface of the heatable workpiece carrier plate. The upper parts of the two driving components are connected to the two movable grippers respectively.

[0029] According to one embodiment of the present invention, it further includes multiple demolding ejector rods, a lifting platform, and a lifting component B for driving the lifting platform to move up and down in the vertical direction;

[0030] The upper surface of the heatable workpiece support plate has a plurality of lifting holes evenly distributed in the middle of the upper surface, extending to its lower surface; a plurality of demolding ejector rods are correspondingly inserted into the plurality of lifting holes, with their upper ends correspondingly located inside the plurality of lifting holes, and their lower ends extending downward to the lower part of the plurality of lifting holes, and are all fixed to the upper surface of the lifting platform, and the bottom of the lifting platform is connected to the lifting component B.

[0031] According to one embodiment of the present invention, a pressure-relieving member is further included; the pressure-relieving member is connected between the lifting platform and the lifting member B.

[0032] This application incorporates a lifting component A to drive the floating heating platform of the camera module to rise and fall. Compared to traditional methods, such as those described in the background section, which rely solely on springs to move the camera module's floating heating platform vertically, this application avoids the problem of decreasing elasticity leading to a smaller floating stroke. In other words, this application provides more precise control over the lifting position of the camera module's floating heating platform, resulting in longer service life and better support for the camera module. This leads to a superior fixation effect, where the camera module is ultimately heat-pressed onto the smartphone's back panel. Furthermore, through the aforementioned optimized design, the overall structure of this application exhibits strong practicality, stability, and reliability.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0076] The heating, pressure-holding, and anti-top fixture 1000 of the present invention will now be described in detail with reference to the accompanying drawings.

[0077] Reference Figures 1 to 7 As shown, the heating and pressure-holding reverse-top fixture 1000 provided according to the embodiment of the present invention is suitable for placing a mobile phone back panel, the mobile phone back panel having a downwardly protruding camera module. The present application includes a fixture seat 10, a floating heating support 20 for the camera module and a lifting component A30.

[0078] The fixture base 10 includes a heatable workpiece support plate 101 suitable for fixing the back panel of the mobile phone. The upper end of the heatable workpiece support plate 101 has a lifting port 1011 facing the camera module.

[0079] Furthermore, the floating heating platform 20 of the camera module is embedded in the lifting port 1011 and fixed on the upper part of the lifting member A30, so that it can float in the vertical direction by being driven by the lifting member A30; when the back panel of the mobile phone is pressed against the upper surface of the heatable workpiece support plate 101, the floating heating platform 20 of the camera module can rise to elastically resist the camera module.

[0080] Based on the above, it is clear that in specific implementation, this application is mainly used as a heating, pressure-holding, and anti-top fixture 1000 for fixing the back panel of a smartphone and the camera module that needs to be pressed and fixed therewith.

[0081] Specifically, when applying this application, the application is assembled according to the structure described above. The camera module floating heating support 20 is driven to descend to the lowest position by the lifting component A30. Then, the application is used to fix the smartphone back panel and the camera module to be pressed and fixed thereto on the upper surface of the heatable workpiece support plate 101, so that the camera module to be fixed is locked and limited in the lifting port 1011. At this time, a layer of HAF adhesive block is pre-set between the camera module to be fixed and the corresponding back panel. Subsequently, the camera module floating heating support 20 is driven to rise to a certain height by the lifting component A30 until it abuts against the bottom surface of the camera module to be fixed. Finally, the workpiece pressing jig head is driven to descend a certain stroke, which can heat-press and fix the smartphone back panel and the camera module to be pressed and fixed thereto together.

[0082] Regarding the above, it is clear that:

[0083] Firstly, this application provides the lifting component A30 to drive the floating heating support 20 of the camera module to rise and fall. Compared with the traditional method described in the background of this application, which only uses springs to make the floating heating support 20 of the camera module float in the vertical direction, this application does not have the problem of the elastic force gradually decreasing and the floating stroke decreasing. In other words, this application can control the lifting position of the floating heating support 20 of the camera module more precisely, resulting in a longer service life and better support for the corresponding camera module, so that the final fixation effect of heat-pressing it together with the back panel of the smartphone is better.

[0084] Secondly, the heatable workpiece support plate 101 and the floating heating platform 20 of the camera module described in this application obviously both have heating functions, so that after heating, they can conduct heat upward to the HAF adhesive block that is attached, so as to promote rapid heat melting, so that the corresponding camera module and other components and the back panel of the smartphone can be quickly heat-pressed and fixed together.

[0085] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical, stable, and reliable in use.

[0086] Furthermore, in specific implementation, in accordance with... Figure 2 and Figure 4 As shown, according to an embodiment of the present invention, the heatable workpiece support plate 101 includes a heating plate 101a, a heat insulation plate 102b and a bottom support plate 103c that are stacked and fixed in sequence from top to bottom;

[0087] The heating plate 101a has a plurality of heating channels A extending into its interior evenly on its side wall. Each heating channel A has a heating rod A1012 extending outward therefrom fixedly installed in its interior. The heating plate 101a also has at least one temperature detection line A1013 connected outward to its side wall.

[0088] Furthermore, the heating plate 101a, the heat insulation plate 102b, and the bottom support plate 103c, which are stacked and fixed together, have lifting ports 1011 that penetrate their upper and lower end faces.

[0089] As described above, it is clear that, on the one hand, by setting the heat insulation plate 102b for heat insulation, the heating plate 101a, after being heated, can conduct heat upwards as much as possible to the HAF adhesive attached to the upper surface of the smartphone back panel, so that the attached HAF adhesive heats up quickly and can melt rapidly. On the other hand, by setting the heat insulation plate 102b for isolation, the components such as the bottom support plate 103c located below the heat insulation plate 102b are not easily deformed by heat, so that the components such as the bottom support plate 103c located below the heat insulation plate 102b have a long service life and stable performance.

[0090] Furthermore, by connecting multiple heating rods A1012 to a heating component, the heating plate 101a can be heated evenly, making it heat up quickly and effectively transferring heat upwards to the HAF adhesive attached to the upper surface of the smartphone back panel, so that the attached HAF adhesive can be heated and melted quickly.

[0091] Meanwhile, by connecting a main control device to the temperature detection line A1013, the heating temperature of the heating plate 101a can be detected in real time, so that the operator can know in real time whether the heating temperature of the heating plate 101a has reached the specified requirements.

[0092] Therefore, through the above-mentioned optimized design, the overall usability of this application can be effectively improved.

[0093] Furthermore, in specific implementation, in accordance with... Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, according to an embodiment of the present invention, the floating heating platform 20 for the camera module includes a heating block 201, a heat insulation block 202, and a lifting block 203;

[0094] The heating block 201, the heat insulation block 202, and the lifting block 203 are fixed together as a whole from top to bottom; the bottom of the lifting block 203 is connected to the top of the lifting component A30.

[0095] Furthermore, the heating block 201 has a heating channel B extending into its interior on its side wall. A heating rod B2011 extending outward is fixed inside the heating channel A, and a temperature detection line B2012 is also connected outward to the side wall of the heating block 201.

[0096] Based on the same principle, in this application, on the one hand, the heat insulation block 202 is used for heat insulation, so that after the heating block 201 is heated, it can conduct heat upward as much as possible to the HAF adhesive attached to the upper surface of the back panel of the smartphone, so that the attached HAF adhesive is heated quickly and can melt rapidly. On the other hand, the heat insulation block 202 is used for isolation, so that the lifting block 203 and other components located below the heat insulation block 202 are not easily deformed by heat, so that the lifting block 203 and other components located below the heat insulation block 202 have a long service life and stable performance.

[0097] Furthermore, by connecting multiple heating rods B2011 to a heating component, the heating block 201 can be heated uniformly, ensuring that it heats up quickly and effectively conducts heat upwards to the HAF adhesive attached to the upper surface of the smartphone back panel, thus ensuring that the attached HAF adhesive can be heated and melted quickly.

[0098] Meanwhile, by connecting a main control device to the temperature detection line B2012, the heating temperature of the heating block 201 can be detected in real time, so that the operator can know in real time whether the heating temperature of the heating block 201 has reached the specified requirements.

[0099] Furthermore, in a specific implementation, according to an embodiment of the present invention, the floating heating support 20 for the camera module further includes a U-shaped seat 204, a fixing ring 205, and a floating limiting pin 206;

[0100] The U-shaped seat 204 is fixed to the bottom surface of the base plate 103c and faces the lifting port 1011. The left and right sides of the inner bottom surface of the U-shaped seat 204 are respectively provided with guide holes 2041 that penetrate to the bottom surface of the base plate 103c. The bottom sides of the lifting block 203 are provided with two guide posts 2031 that are corresponding to the two guide holes 2041 and pass through them from top to bottom with an interference fit.

[0101] Furthermore, the fixing ring 205 is fixed to the top of the lifting component A30; the floating limiting pin 206 passes through the fixing ring 205, and its left and right ends are fixed between the lower ends of the two guide posts 2031; the inner diameter of the fixing ring 205 in the vertical direction is larger than the outer diameter of the floating limiting pin 206 in the vertical direction.

[0102] Initially, the lower bottom surface of the floating limit pin 206 is in contact with the lower inner wall of the fixed ring 205, and a lifting gap is formed between the upper inner wall of the fixed ring 205 and the upper top surface of the floating limit pin 206.

[0103] Therefore, by setting up a camera module floating heating platform 20 with the above-described structure, including a heating block 201, a heat insulation block 202, a lifting block 203, a U-shaped seat 204, a fixing ring 205, and a floating limit pin 206, we can conclude that:

[0104] On the one hand, the two guide holes 2041 provided can play a good guiding role, so as to limit the two guide columns 2031 to move up and down in the vertical direction, so that the heating block 201 used to support the camera module has good lifting stability and good lifting flatness.

[0105] On the other hand, by setting the fixed ring 205 and the floating limiting pin 206, and limiting that in the initial state, a lifting gap is formed between the inner top wall of the fixed ring 205 and the upper top surface of the floating limiting pin 206, the lifting range of the heating block 201 used to support the camera module is limited, so that the lifting component will not drive the heating block 201 to rise too much due to misoperation, which would damage the camera module to be supported.

[0106] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be further improved.

[0107] Furthermore, in this technical solution, compared with... Figure 6 and Figure 7 As shown, according to an embodiment of the present invention, the floating heating platform 20 for the camera module further includes a counter-top spring 207, a connecting block 208, and a pressure sensor 209;

[0108] The lifting block 203 has an upper slot 2032 at the bottom center; the U-shaped seat 204 has a lower slot 2042 at the bottom center; the upper end of the anti-top spring 207 is fixed to the upper slot 2032, and the lower end is connected to the upper surface of the connecting block 208; the lower bottom surface of the connecting block 208 is fixed to the upper part of the pressure sensor 209, and the lower part of the pressure sensor 209 is fixed in the lower slot 2042.

[0109] Therefore, when the floating heating platform 20 for the camera module described in this application also includes the anti-top spring 207, the connecting block 208, and the pressure sensor 209, the following effects can be achieved:

[0110] Firstly, initially, that is, when this application is not in use, the lifting component A30 drives the floating heating platform 20 of the camera module to rise to the highest position. At this time, the heating block 201 of the floating heating platform 20 of the camera module will be basically flush with the upper part of the lifting port 1011. It will not exert downward pressure on the anti-top spring 207, so that the anti-top spring 207 will be in a natural state. It will not gradually lose its elasticity due to being in a compressed state for a long time. In other words, this application sets the lifting component A30 to work with the anti-top spring 207 so that the anti-top spring 207 is not subjected to downward pressure when not in use, thereby extending its service life.

[0111] Secondly, when using this application, firstly, the lifting component A30 drives the floating heating support 20 of the camera module to descend to its lowest position. Then, using this application, the smartphone back panel and the camera module to be pressed and fixed thereto are fixed on the upper surface of the heatable workpiece support plate 101, so that the camera module to be fixed is locked and limited within the lifting port 1011. At this time, a layer of HAF adhesive block is pre-set between the camera module to be fixed and the corresponding back panel. Subsequently, the lifting component A30 drives the floating heating support 20 of the camera module to descend to its lowest position. The heated support platform 20 rises to a certain height until it abuts against the bottom surface of the camera module to be fixed. Finally, the workpiece pressing fixture head is driven to descend a certain stroke, which can heat-press and fix the smartphone back panel and the camera module to be pressed and fixed together. During this heat-pressing process, the anti-top spring 207 is in a compressed state, which will generate an upward reaction force to push the bottom surface of the camera module to be fixed, so that the camera module to be fixed has a good heat-pressing and fixing effect on both the top and bottom sides, and the camera module to be fixed is more firmly fixed.

[0112] Thirdly, when the lifting component A30 drives the floating heating platform 20 of the camera module to rise to a certain height and abut against the bottom surface of the camera module to be fixed, the heating block 201 of the floating heating platform 20 of the camera module does not rigidly press against the bottom surface of the camera module to be fixed. Instead, it is buffered by the anti-top spring 207, so that the camera module to be fixed is not easily damaged by the sudden impact, making the reliability of this application better.

[0113] Fourthly, by setting the pressure sensor 209, the pressure applied by the floating heating support 20 to the bottom surface of the camera module to be fixed can be detected, so that the pressure is monitored in real time if it is too high or too low, so that the operator can adjust it in time.

[0114] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be further improved.

[0115] It should be added that, in a specific implementation, according to an embodiment of the present invention, the fixture base 10 further includes a fixed base plate 102 and a plurality of support columns 103 for supporting the base plate 103c.

[0116] Among them, multiple support columns 103 are respectively fixed between the periphery of the upper end surface of the fixed base plate 102 and the periphery of the lower bottom surface of the base plate 103c; the lifting component A30 is fixed to the upper end surface of the fixed base plate 102.

[0117] It should also be added that, in specific implementation, comparison should be made with... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, this application further includes a plurality of gripper components 40 for clamping and fixing the back panel of the mobile phone; the plurality of gripper components 40 are uniformly fixed to the periphery of the upper end surface of the heatable workpiece support plate 101.

[0118] Preferably, in a specific implementation, according to an embodiment of the present invention, the gripper member 40 includes fixed grippers 401 fixed on adjacent sides of the upper end face of the heatable workpiece support plate 101 and movable grippers 402 fixed on other adjacent sides of the upper end face of the heatable workpiece support plate 101.

[0119] The fixed base plate 102 has two driving components 50 installed on its upper surface to control the movement of the two movable grippers 402 toward the center of the upper surface of the heatable workpiece support plate 101. The upper parts of the two driving components 50 are connected to the two movable grippers 402.

[0120] Therefore, this application uses the two fixed grippers 401 and the two movable grippers 402 to clamp and fix the back panel of the smartphone, making it difficult for the fixed smartphone back panel to shift circumferentially.

[0121] Preferably, in this technical solution, both driving components 50 are preferably cylinder driving components, cylinder transmission linear modules, or lead screw transmission linear modules.

[0122] Furthermore, it is necessary to add that, in specific implementation, comparison should be made with... Figure 2 and Figure 4 According to one embodiment of the present invention, this application also includes multiple demolding ejector rods 60, a lifting platform 70, and a lifting component B80 for driving the lifting platform 70 to move up and down in the vertical direction;

[0123] The upper surface of the heatable workpiece support plate 101 has a plurality of lifting holes 1014 that extend to its lower surface. Multiple demolding ejector rods 60 are correspondingly inserted into the multiple lifting holes 1014, with their upper ends located inside the multiple lifting holes 1014 and their lower ends extending downward to the lower part of the multiple lifting holes 1014. They are all fixed to the upper surface of the lifting platform 70, and the bottom of the lifting platform 70 is connected to the lifting component B80.

[0124] Therefore, it can be clearly understood that after the corresponding camera module and other components are hot-pressed and fixed to the smartphone back panel, the two driving components 50 drive the two movable grippers 402 to move a certain distance away from the center of the upper surface of the heatable workpiece support plate 101. Then, the lifting component B80 drives the multiple demolding ejector rods 60 to rise. The tops of the multiple demolding ejector rods 60 will extend to the upper part of the multiple lifting holes 1014 and lift the whole consisting of the corresponding camera module and other components and the smartphone back panel that are hot-pressed together. In this way, the whole consisting of the corresponding camera module and other components and the smartphone back panel can be unloaded and transferred.

[0125] Preferably, in this technical solution, according to an embodiment of the present invention, the application further includes a pressure-relieving member 90; the pressure-relieving member 90 is connected between the lifting platform 70 and the lifting member B80, and the pressure-relieving member 90 is preferably a pressure-relieving spring.

[0126] Therefore, by setting the pressure-reducing component 90 to buffer the pressure, even when the lifting component B80 drives multiple demolding ejector rods 60 to rise so that their tops extend beyond the upper part of multiple lifting holes 1014 to lift the overall structure formed by the corresponding camera module and other components and the smartphone back panel that are fixed together by heat pressing, the tops of the multiple demolding ejector rods 60 do not rigidly lift the overall structure formed by the corresponding camera module and other components and the smartphone back panel that are fixed together by heat pressing. This makes it less likely for the overall structure formed by the corresponding camera module and other components and the smartphone back panel that are fixed together by heat pressing to be broken all at once, so that the reliability of this application is optimal.

[0127] Furthermore, in specific implementation, the lifting component A30 and lifting component B80 in this embodiment are preferably lifting cylinders, cylinder transmission linear modules or screw transmission linear modules that are fixed to the upper surface of the fixed base plate 102 in a vertical direction.

[0128] Other embodiments, etc., will not be described here.

[0129] In summary, this application incorporates the lifting component A30 to drive the floating heating platform 20 of the camera module to rise and fall. Compared to traditional methods, such as those described in the background section of this application, which rely solely on springs to move the floating heating platform 20 vertically, this application avoids the problem of decreasing elasticity leading to a smaller floating stroke. In other words, this application provides more precise control over the lifting position of the floating heating platform 20, resulting in longer service life and better support for the camera module. This leads to a superior fixation effect, where the camera module is ultimately heat-pressed onto the smartphone back panel. Furthermore, through the aforementioned optimized design, the overall structure of this application exhibits strong practicality, stability, and reliability.
