Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, and in particular to a single-power, multiple-weight, individually heated and pressure-maintained jig. 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 flat pressing with adhesive. For example, small parts such as the camera and lighting of a smartphone need to be fixed to its back panel by flat pressing with hot melt adhesive.

[0003] Conventionally, when pressing and fixing two corresponding workpieces, a jig table is generally set up to fix the large workpiece, and multiple small workpieces are glued to the upper surface of the corresponding large workpiece by applying hot melt adhesive, and a workpiece pressing jig head with a heating plate with a flat bottom surface is set above the corresponding jig table. The corresponding workpiece pressing jig head moves downward for a certain stroke to press down the corresponding multiple small workpieces for a certain period of time. When the corresponding hot melt adhesive is hot-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 workpiece pressing fixture head used is basically provided with a workpiece pressing plate and a counter-top spring fixed on the upper part of the corresponding workpiece pressing 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, which increases maintenance costs and manpower. On the other hand, due to the different installation positions of the HAF glue, the upper end faces thereof will have very subtle height differences from each other, so that the upper end faces of the multiple small workpieces installed subsequently will also have very subtle height differences from each other, so that when the workpiece pressing fixture head 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] 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.

[0077] The following describes in detail a single-power, multiple-weight, individual heating and pressure-maintaining jig 1000 according to an embodiment of the present invention with reference to the accompanying drawings.

[0078] Reference Figures 1 to 8 As shown, a single-power, multiple-weight, separate heating and pressurizing fixture 1000 according to an embodiment of the present invention includes a power plate 10, a workpiece pressing plate 20, a pressing plate supporting member 30, a plurality of heat-pressing columns 40 for pressing a part of the workpiece, and a plurality of weight members 50 for applying downward pressure to the plurality of heat-pressing columns 40;

[0079] The pressure plate supporting members 30 are provided in plurality and are evenly fixed downwardly on the outer periphery of the power plate 10, and a support block 301 is provided horizontally at the lower end thereof toward the middle and lower part of the power plate 10; the workpiece pressure plate 20 is limited to be directly below the power plate 10 and is supported by the plurality of support blocks 301, and the workpiece pressure plate 20 is provided with a plurality of pressure holes 201 penetrating the upper and lower end surfaces thereof;

[0080] In addition, the power plate 10 is provided with a plurality of through grooves 101 passing through its upper and lower end surfaces and corresponding to the plurality of pressure holes 201; the lower ends of the plurality of heat pressurized columns 40 are correspondingly limited in the plurality of pressure holes 201, and the inner diameters of the bottoms of the plurality of pressure holes 201 are slightly smaller than the outer diameters of the tops, so as to support the plurality of heat pressurized columns 40, and the upper ends of the plurality of heat pressurized columns 40 are correspondingly limited in the plurality of through grooves 101; the plurality of weight components 50 are correspondingly detachably placed on the upper parts of the plurality of through grooves 101.

[0081] Based on the above, it is clear that when the present application is implemented, it is mainly used as a single-power multiple-weight separate heating and pressure-maintaining fixture 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.

[0082] Specifically, when applying the present application, the present application is assembled according to the structure described above, and a jig table is used to fix a large workpiece (such as the back panel of a mobile phone, etc.) in advance. Then, a piece of HAF glue is affixed to multiple preset positions on the upper end surface of the fixed large workpiece. Subsequently, a heating pre-pressing mechanism is used to pre-melt the corresponding multiple pieces of HAF glue to a certain degree. 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 present application can be used to press and fix the corresponding large workpiece and multiple small workpieces that are bonded together.

[0083] From the above, it is clear that:

[0084] First, the present application is provided with the workpiece pressing plate 20. After the present application is lowered to a certain height, the workpiece pressing plate 20 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 at the positions of the multiple pressing holes 201. When the present application continues to descend to a certain height, the bottoms of the multiple hot pressurizing columns 40 will naturally reach the upper end faces of the corresponding multiple small workpieces. At this time, the multiple weight components 50 are placed on the multiple through slots 101. When the weight components 50 are in the upper part, the bottom thereof will naturally reach the top of the multiple heat-pressing columns 40, so as to apply downward pressure to the multiple heat-pressing columns 40 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 50 to replace the multiple anti-top springs 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 50 remains basically unchanged for a long time, which can also greatly reduce the replacement cost and maintenance cost.

[0085] Second, after the multiple heat-pressurizing columns 40 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 the present application, each piece of HAF glue is also heated and pressurized separately, so that the multiple pieces of HAF glue will melt evenly, so that a better hot melting effect can be achieved quickly, so that the multiple corresponding small workpieces can be well fixed by hot pressing.

[0086] Furthermore, through the above-mentioned optimized design, 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. On the basis of the provided pressing intensity being able to remain constant for a long time, the multiple pieces of HAF glue corresponding to the bottom of the corresponding multiple small workpieces are indeed heat-melted evenly, so that the best heat-melting effect can be achieved quickly, so that the multiple corresponding small workpieces can indeed be well fixed by hot pressing. As a result, the present application is highly practical and effective to use.

[0087] Furthermore, in specific implementation, Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the present application further includes a plurality of pressure relief members 60;

[0088] Among them, the upper end surface of the power plate 10 is respectively provided with pressure-relief grooves 102 downwardly beside the multiple through grooves 101, and the upper end outer walls of the multiple heat-pressurized columns 40 are respectively protruding outward with ears 401 facing the pressure-relief grooves 102 at similar positions; the multiple pressure-relief components 60 are correspondingly clamped in the multiple pressure-relief grooves 102, and their upper ends are correspondingly against the lower bottom surfaces of the multiple ears 401.

[0089] It should be noted here that the above-mentioned multiple pressure-relief components 60 in this application all provide a certain buffering force, so that when the multiple weight components 50 are placed on the upper part of the multiple through grooves 101 to apply downward pressure to the multiple hot pressurizing columns 40 to hot press the corresponding multiple small workpieces, the multiple hot pressurizing columns 40 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 the use of this application more stable and reliable.

[0090] Preferably, in this embodiment, two pressure-relieving grooves 102 are respectively opened downwardly and oppositely on the periphery of the plurality of through grooves 101 on the upper end surface of the power plate 10, and two ears 401 are respectively protruded outward on the outer walls of the upper ends of the plurality of the heat-pressurized columns 40, which are directly opposite to the two pressure-relieving grooves 102 at similar positions; a pressure-relieving component 60 is respectively clamped in each of the pressure-relieving grooves 102, so that the stability of the pressure relief of the plurality of the heat-pressurized columns 40 in the vertical direction can be better maintained.

[0091] And preferably, in this embodiment, each of the pressure relief components 60 is a spring pressure relief component, which is common in the prior art, so its details are not described in detail here.

[0092] Furthermore, in the specific implementation, Figure 2 、 Figure 4 and Figure 7As shown, according to one embodiment of the present invention, each of the weight components 50 includes a columnar reference weight 501 and a plurality of detachable sheet-like tiny weight pieces 502 stacked on top of the reference weight 501;

[0093] The lower ends of the reference weights 501 are correspondingly inserted into the upper inner portions of the through slots 101 , and the bottoms thereof are correspondingly against the upper surfaces of the heat-pressurizing columns 40 .

[0094] It should be noted here that when actually using this application, in order to pre-detach multiple said tiny weight pieces 502 and retain multiple said reference weights 501, so that they can be inserted into the upper part of multiple said through slots 101 and their bottoms can be correspondingly against the tops of multiple said hot pressurizing columns 40, when it is necessary to pressurize the corresponding multiple small workpieces later, according to actual needs, a suitable number of said tiny weight pieces 502 can be stacked on top of the said reference weights 501 at different positions, so that when the present application uses multiple said weight components 50 to press down multiple said hot pressurizing columns 40, the downward pressure can also be flexibly adjusted, so that the overall use effect of the present application can be effectively improved.

[0095] Furthermore, in a specific implementation, according to one embodiment of the present invention, the present invention further includes a plurality of vertical guide rails 70 and a plurality of corresponding sliders 80 that can move up and down and are provided on the plurality of vertical guide rails 70;

[0096] The plurality of vertical guide rails 70 are vertically fixed on the upper end surface of the power plate 10 ; and the plurality of sliders 80 are correspondingly fixed on the outer walls of the plurality of reference weights 501 .

[0097] It should be noted here that, since in actual use, the lengths of the multiple reference weights 501 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 101, the present application provides multiple vertical guide rails 70 and multiple corresponding sliders 80 that can move up and down on the multiple vertical guide rails to fix the multiple reference weights 501 accordingly, so that the placement stability of the multiple reference weights 501 is effectively improved, and they can also move stably in the up and down directions, so that they are not easy to shake or tip over during use.

[0098] In addition, in a specific implementation, according to one embodiment of the present invention, each of the reference weights 501 is provided with a vertically detachable fixing pin 5011 on the top; and a plurality of the tiny weight pieces 502 are respectively provided with fixing holes 5021 penetrating the upper and lower end surfaces thereof for the fixing pin 5011 to pass through.

[0099] Preferably, in this embodiment, two fixing pins 5011 are vertically provided on the top of each reference weight 501; and two fixing holes 5021 are respectively opened on the plurality of tiny weight pieces 502 and pass through the upper and lower end surfaces thereof for the two fixing pins 5011 to pass through.

[0100] In this way, when the plurality of tiny weight pieces 502 are stacked and fixed on the top of the reference weight 501 , the stacking is stable and will not slide off, so that the plurality of weight components 50 of the present application also have excellent stability in use.

[0101] Furthermore, in the specific implementation, Figure 1 、 Figure 2 and Figure 5 As shown, according to one embodiment of the present invention, the present invention further includes a limiting block 90 for correspondingly limiting the downward pressing stroke of the plurality of weight members 50;

[0102] The plurality of limit blocks 90 are horizontally fixed on the upper end surface of the power plate 10, and one end of each of the limit blocks 90 extends above the plurality of through slots 101; the outer walls of the lower ends of the reference weights 501 of the plurality of weight members 50 are respectively provided with limit slots 5012 suitable for inserting one end of the limit blocks 90 at the corresponding positions;

[0103] Initially, there is a certain distance between the upper end surface of one end of each of the limiting blocks 90 and the inner top surface of the limiting groove 5012 at the corresponding position, and the corresponding multiple distances form corresponding multiple maximum downward pressing strokes.

[0104] From this, it can be clearly seen that when a plurality of the limit blocks 90 are provided in the present application to limit the downward stroke of the plurality of the weight components 50, the protection effect is good when a plurality of small workpieces are pressed down accordingly, and human error will not cause a large number of tiny weight pieces 502 to be stacked on top of a certain reference weight 501, resulting in excessive downward pressure and crushing the small workpieces to be pressed down and fixed.

[0105] Furthermore, through the above-mentioned optimized design, the overall use effect of the present application can be further improved.

[0106] It should be added that, in the specific implementation, Figure 2 、 Figure 3 、 Figure 4 and Figure 7 As shown, according to one embodiment of the present invention, the present application further includes a plurality of guide posts 100 and a plurality of pressure springs 110;

[0107] Among them, the workpiece pressure plate 20 is evenly opened with a plurality of guide holes 202 passing through its upper and lower end surfaces on its periphery; a plurality of the guide columns 100 are evenly fixed downward on the periphery of the lower bottom surface of the power plate 10, and their lower ends are interference fit and movably passed through the plurality of the guide holes 202; a plurality of the top pressure springs 110 are evenly fixed between the periphery of the lower bottom surface of the power plate 10 and the periphery of the upper end surface of the workpiece pressure plate 20.

[0108] Initially, the workpiece pressing plate 20 is supported by the plurality of supporting blocks 301 , and the plurality of pressing springs 110 are in a natural state or a compressed state.

[0109] From this, it can be clearly seen that after the application is lowered to a certain height, the workpiece pressing plate 20 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 HAF glues fixed on the upper end face of the large workpiece will be located correspondingly at the positions of the multiple pressing holes 201. When the application continues to descend to a certain height, when the bottoms of the multiple hot pressurizing columns 40 correspond to the upper end faces of the multiple small workpieces, the multiple pressure springs 110 will be compressed to provide a reverse force to push down the workpiece pressing plate 20, so that the workpiece pressing plate 20 can apply a certain downward pressure to press the fixed large workpiece.

[0110] Moreover, since the workpiece pressure plate 20 is evenly provided with a plurality of guide holes 202 penetrating the upper and lower end surfaces thereof around its periphery; and a plurality of the guide posts 100 are evenly fixed downwardly on the periphery of the lower bottom surface of the power plate 10, and their lower ends are interference fit and movably passed through the plurality of guide holes 202, therefore, when the present application is actually used, by providing the guide posts 100 for upward and downward guidance, the workpiece pressure plate 20 can be accurately displaced in the upward and downward directions and is not easily displaced circumferentially, thereby further improving the stability and reliability of the present application.

[0111] It should also be added that, in the specific implementation, reference Figure 2 and Figure 4 As shown, according to one embodiment of the present invention, each of the heat-pressurized columns 40 includes a copper column 40a, a heat-insulating block 40b, and an extension column 40c;

[0112] The copper column 40a, the heat-insulating block 40b and the extension column 40c are sequentially connected from bottom to top; the upper outer walls of the plurality of extension columns 40c are respectively provided with ears 401 protruding outwards and facing the pressure-relieving grooves 102 at adjacent positions.

[0113] From the above, it can be understood that, on the one hand, the present application provides heat insulation by setting the thermal insulation block 40b, so that after the copper column 40a is heated, it can transfer the heat downward to the corresponding multiple small workpieces pressed together as much as possible, so that the multiple blocks of HAF glue corresponding to the bottom of the multiple corresponding small workpieces are heated quickly so as to be able to melt quickly. On the other hand, the present application provides isolation by setting the thermal insulation block 40b, so that the extension column 40c and the weight component 50 located on the upper part of the thermal insulation block 40b are not easily deformed by heat, so that the extension column 40c and the weight component 50 located on the upper part of the thermal insulation block 40b have a long service life and more stable performance.

[0114] Again, in the specific implementation, according to one embodiment of the present invention, each side wall of the copper column 40a is provided with a heating channel extending into the interior thereof, each heating channel is respectively fixed with a heating rod 40a1 extending outward thereof, and each side wall of the copper column 40a is also respectively connected to the outside with a temperature detection line 40a2.

[0115] From this, it can be clearly seen that:

[0116] On the one hand, by connecting multiple heating rods 40a1 to a heating component, multiple copper pillars 40a can be heated separately. When they are heated independently, due to their small volume and size, they are heated quickly as a whole, and can indeed quickly transfer heat downward to the multiple pieces of HAF glue arranged at the bottom, so that the multiple pieces of HAF glue can be quickly heated and melted evenly, so that a better melting effect can be achieved quickly, so that multiple corresponding small workpieces can be well fixed by hot pressing.

[0117] On the other hand, by setting up multiple temperature detection lines 40a2 connected to an external main control device, the heating temperature of multiple copper pillars 40a can be detected in real time, so that the operator can know in real time whether the heating temperature of multiple copper pillars 40a meets the specified requirements.

[0118] Furthermore, according to one embodiment of the present invention, the present application further includes a plurality of pressure sensors 120;

[0119] The top surfaces of the extension columns 40c are each provided with a slot 40c1 downwardly; the pressure sensors 120 are correspondingly fixed in the slots 40c1; and the lower ends of the reference weights 501 are correspondingly pressed against the top surfaces of the pressure sensors 120.

[0120] By providing a plurality of pressure sensors 120, the pressure applied by the plurality of heat pressurizing columns 40 to the plurality of small workpieces can be detected accordingly, so that when the pressure applied by a certain heat pressurizing column 40 to a certain small workpiece is too high or too low, it can be monitored in real time, so that the operator can make timely adjustments.

[0121] Again, in the specific implementation, according to one embodiment of the present invention, a connecting seat 103 is provided upwardly in the middle of the upper end surface of the power plate 10; the connecting seat 103 is suitable for connecting to a lifting device, and the lifting device is preferably a lifting cylinder, a cylinder-driven linear module or a screw-driven linear module.

[0122] Other embodiments and the like are not described here as examples.

[0123] To sum up, the single-powered multiple-weight individual heating and pressurizing jig 1000 provided by the present invention, in specific implementation, the overall structure of the present application adopts a single-powered multi-point heating and pressurizing method to heat and pressurize multiple small workpieces separately. The present application adopts multiple weight components 50 to replace the multiple anti-top springs used in the traditional way to provide downward pressure, which can keep the downward pressure on multiple small workpieces constant for a long time, making the present application more stable and reliable to use, and the quality of the multiple weight components 50 remains basically unchanged for a long time, which can also greatly reduce replacement costs and maintenance costs.

[0124] Moreover, on the basis of the fact that the pressure provided by the present application can be kept constant for a long time, the multiple pieces of HAF glue corresponding to the bottom of the corresponding multiple small workpieces can be evenly melted, so that the best hot melting effect can be achieved quickly, so that the multiple corresponding small workpieces can be well fixed by hot pressing. Therefore, the present application is highly practical and effective to use.
