Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a multi-position heating and pressure-holding 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 smartphones 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. Above the fixture is a workpiece pressing fixture head with a flat bottom surface. As the workpiece pressing fixture head moves downward 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] Because the hot melt adhesive used is HAF adhesive, which is not tacky at room temperature and only becomes tacky after being pressurized and heated, a heating pre-pressing mechanism is needed to pre-melt the hot melt adhesive on the surface of the large workpiece to a certain degree before pressing and fixing the large workpiece and multiple small workpieces together. Only then can the multiple small workpieces be attached to it, and then the large workpiece and multiple small workpieces that are attached together can be pressed and fixed.

[0005] In actual operation, due to the different placement positions of the HAF adhesive, there are very slight height differences between their upper surfaces. This results in slight height differences between the upper surfaces of the subsequent small workpieces. Consequently, when using a workpiece pressing fixture head with a flat bottom plate to simultaneously heat and pressurize the workpieces, the smaller workpieces with lower upper surfaces cannot receive adequate heating and pressurization. Furthermore, since the smaller workpieces are generally quite small, the downward heat conduction of the larger heating plate is uneven before it is fully heated, leading to uneven and asynchronous heating of the smaller workpieces. This prevents the heat from being quickly and synchronously conducted to the HAF adhesive pieces on their lower surfaces to promote rapid melting.

[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 multi-position heating and pressure-holding fixture.

[0008] To achieve the above objectives, a multi-position heating and pressure-holding fixture according to an embodiment of the present invention includes a power plate, a workpiece pressure plate, a pressure plate support component, multiple top pressure springs A, and multiple heat-pressurizing columns for pressing local parts of the workpiece.

[0009] The pressure plate support component is provided in multiple ways and is evenly fixed downward on the outer periphery of the power plate. A support block is provided horizontally at the lower end of the pressure plate towards the center and lower part of the power plate. The workpiece pressure plate is limited to the lower part of the power plate and is supported by the multiple support blocks. The workpiece pressure plate has multiple pressure holes that penetrate its upper and lower end faces.

[0010] The bottom surface of the power plate has multiple fixing slots facing upwards, corresponding to the multiple pressure holes; multiple top pressure springs A are vertically fitted into the multiple fixing slots, and multiple hot pressurizing columns are fixed at their lower ends; the multiple hot pressurizing columns are correspondingly limited in the multiple pressure holes, and can move up and down along the multiple pressure holes.

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

[0012] According to one embodiment of the present invention, it further includes multiple guide posts and multiple top compression springs B;

[0013] The workpiece pressure plate has multiple guide holes evenly distributed around its upper and lower end faces; multiple guide pillars are evenly fixed downwards around the lower bottom surface of the power plate, with their lower ends corresponding to an interference fit and movably inserted into the multiple guide holes; multiple top pressure springs B are evenly fixed between the lower bottom surface of the power plate and the upper top surface of the workpiece pressure plate.

[0014] According to one embodiment of the invention, it further includes a removable plate for maintaining the elastic force of the plurality of compression springs A;

[0015] The detachable plate is fixedly attached to the bottom surface of the workpiece pressure plate to block multiple pressure holes and support multiple hot press columns. Its periphery is detachably fixed to the workpiece pressure plate and / or multiple support blocks by fastening bolts.

[0016] According to one embodiment of the present invention, it further includes a plurality of detachable seats;

[0017] Multiple fixing slots extend through the upper surface of the power plate, and multiple detachable seats are correspondingly and detachably fixed in the multiple fixing slots; the upper ends of multiple top pressure springs A are correspondingly connected to the multiple detachable seats.

[0018] According to one embodiment of the present invention, it further includes a plurality of fixing blocks and a plurality of pressure sensors;

[0019] Each of the detachable seats has an upward-facing receiving groove at its bottom; the fixing blocks are correspondingly fixed between the upper ends of the multiple top pressure springs A and the bottoms of the multiple pressure sensors; the multiple pressure sensors are correspondingly fixedly installed in the multiple receiving grooves.

[0020] According to one embodiment of the present invention, each of the heat-pressurizing columns includes a copper column, a heat insulation block, and an extension column;

[0021] The copper pillar, the heat insulation block, and the extension pillar are connected sequentially from bottom to top; the lower ends of the multiple top pressure springs A are correspondingly connected to the upper parts of the multiple extension pillars.

[0022] According to one embodiment of the present invention, each of the copper pillars has a heating channel extending into its interior on its sidewall, and a heating rod extending outward is fixed in each heating channel. Furthermore, each of the copper pillars is connected to a temperature detection line extending outward.

[0023] According to one embodiment of the present invention, a connecting seat is provided at the center of the upper end surface of the power plate; the connecting seat is adapted to be connected to a lifting device.

[0024] The multi-position heating and pressure-holding fixture provided in this application, in its specific implementation, employs a single-power multi-point heating and pressurizing method to individually heat and pressurize multiple small workpieces. This ensures that the multiple HAF adhesives corresponding to the bottom of the various small workpieces are uniformly melted, achieving a rapid and optimal heat-melting effect. Consequently, the various small workpieces are effectively heat-pressed and fixed. Furthermore, since the multiple heating and pressurizing columns do not rigidly heat and pressurize the various small workpieces, they are less likely to be damaged due to rigid force. In addition, this application also has the function of individually detecting the downward pressure and the hot-pressing temperature of the multiple heating and pressurizing columns, resulting in excellent overall performance.

[0065] The multi-position heating and pressure-holding fixture 1000 of the present invention will now be described in detail with reference to the accompanying drawings.

[0066] Reference Figures 1 to 6 As shown, the multi-position heating and pressure holding fixture 1000 provided according to an embodiment of the present invention includes a power plate 10, a workpiece pressure plate 20, a pressure plate support member 30, multiple top pressure springs A40, and multiple heat-pressing columns 50 for pressing the workpiece locally.

[0067] The pressure plate support member 30 is provided in multiple ways and is uniformly fixed downward on the outer periphery of the power plate 10. Each of the lower ends of the pressure plate 30 is provided with a support block 301 horizontally downward on the power plate 10. The workpiece pressure plate 20 is limited to the power plate 10 and is supported by the multiple support blocks 301. The workpiece pressure plate 20 has multiple pressure holes 201 that penetrate its upper and lower end faces.

[0068] Furthermore, the bottom surface of the power plate 10 has multiple fixing grooves 101 corresponding to the multiple pressure holes 201; multiple top pressure springs A40 are vertically fitted into the multiple fixing grooves 101, and multiple hot press columns 50 are fixedly provided at their lower ends; the multiple hot press columns 50 are correspondingly limited in the multiple pressure holes 201, and can move up and down along the multiple pressure holes 201 with an interference fit.

[0069] Based on the above, it is clear that, in specific implementation, this application is mainly used as a multi-position heating and pressure holding fixture 1000 for heating and pressurizing multiple small workpieces corresponding to the upper surfaces of multiple HAF adhesives bonded to the upper end face of a large workpiece.

[0070] Specifically, when applying this application, assemble the application according to the structure described above, first use a jig to fix a large workpiece (such as a mobile phone back panel), then attach a piece of HAF adhesive to multiple preset positions on the upper surface of the fixed large workpiece, then use a heating and pre-pressing mechanism to pre-melt the corresponding HAF adhesive to a certain degree, then attach multiple other small workpieces (such as cameras and lights) to the upper surface of the corresponding HAF adhesive, and finally use this application to press and fix the corresponding large workpiece and multiple small workpieces together.

[0071] Regarding the above, it is clear that:

[0072] Firstly, this application includes a workpiece pressure plate 20. After the application descends to a certain height, the workpiece pressure plate 20 can naturally press against 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 adhesives fixed on the upper surface of the large workpiece will be located at the positions of the multiple pressure holes 201. As the application continues to descend to a certain height, the bottom of one of the heat-pressing columns 50 will reach the upper surface of the small workpiece with the lowest upper surface height. The bottoms of the other heat-pressing columns 50 will also reach the upper surfaces of the small workpieces set at other positions. In this way, the multiple small workpieces can be heated and pressurized well.

[0073] Secondly, since the multiple hot press columns 50 are correspondingly interference-fitted and can move up and down through the multiple pressure holes 201, after the multiple hot press columns 50 are heated, they can directly heat and pressurize the multiple small workpieces. The multiple corresponding small workpieces can then conduct heat to the HAF adhesive at their bottom. In other words, in this application, each piece of HAF adhesive is also heated and pressurized individually, so that the multiple pieces of HAF adhesive will melt evenly, thereby quickly achieving a better melting effect, so that the multiple corresponding small workpieces can be well hot-pressed and fixed.

[0074] Thirdly, since this application is equipped with multiple top pressure springs A40, which are connected to the upper part of multiple hot pressurizing columns 50, the multiple hot pressurizing columns 50 will not rigidly heat and pressurize the corresponding multiple small workpieces, so that the corresponding multiple small workpieces are not easily crushed due to rigid force, making this application stable and reliable in use.

[0075] Furthermore, through the aforementioned optimized design, the entire application employs a single-power multi-point heating and pressurizing method to individually heat and pressurize multiple small workpieces. This ensures that the multiple HAF adhesives corresponding to the bottom of the various small workpieces are uniformly melted, achieving a rapid and optimal melting effect. Consequently, the various small workpieces are effectively heat-pressed and fixed. Moreover, since the multiple heat-pressurizing columns 50 do not rigidly heat and pressurize the various small workpieces, they are less likely to be damaged due to rigid force. Therefore, this application is highly practical and effective in use.

[0076] Furthermore, in specific implementation, in accordance with... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, according to one embodiment of the present invention, this application also includes multiple guide posts 60 and multiple top compression springs B70;

[0077] The workpiece pressure plate 20 has multiple guide holes 202 evenly distributed around its periphery, penetrating its upper and lower end faces; multiple guide posts 60 are evenly fixed downwards around the lower bottom surface of the power plate 10, with their lower ends corresponding to an interference fit and movably inserted into the multiple guide holes 202; multiple top pressure springs B70 are evenly fixed between the lower bottom surface of the power plate 10 and the upper end surface of the workpiece pressure plate 20.

[0078] Initially, the workpiece pressure plate 20 is supported by multiple support blocks 301, and multiple top pressure springs B70 are in a natural or compressed state.

[0079] Therefore, it can be clearly understood that after the application descends to a certain height, the workpiece pressure plate 20 will naturally press against 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 adhesives fixed on the upper surface of the large workpiece will be located at the positions of the multiple pressure holes 201. As the application continues to descend to a certain height, when the bottom of the multiple heat-pressing columns 50 abuts against the upper surfaces of the multiple small workpieces, the multiple top pressure springs B70 will be compressed to provide a reverse force to push down the workpiece pressure plate 20, so that the workpiece pressure plate 20 can apply a certain downward pressure to press against the fixed large workpiece.

[0080] Furthermore, since the workpiece pressure plate 20 has multiple guide holes 202 evenly distributed around its periphery, penetrating its upper and lower end faces; and multiple guide posts 60 are evenly fixed downwards around the lower bottom surface of the power plate 10, with their lower ends corresponding to an interference fit and movably inserted into the multiple guide holes 202, in actual use, by setting the guide posts 60 for vertical guidance, the workpiece pressure plate 20 can be accurately displaced in the vertical direction and is not easily displaced circumferentially, making the use of this application more stable and reliable.

[0081] Furthermore, in a specific implementation, according to an embodiment of the present invention, this application also includes a detachable plate 80 for maintaining the elastic force of the plurality of top compression springs A40;

[0082] The detachable plate 80 is fixedly attached to the bottom surface of the workpiece pressure plate 20 to block multiple pressure holes 201 and support multiple hot press columns 50. Its periphery is detachably fixed to the workpiece pressure plate 20 and / or multiple support blocks 301 by fastening bolts 90.

[0083] Therefore, it can be understood that before the present application is used, the lower ends of the multiple top pressure springs A40 are correspondingly fixed with multiple heat-pressing columns 50. Each of the multiple heat-pressing columns 50 has a certain weight, which will correspondingly stretch the multiple top pressure springs A40. As a result, the elasticity of the multiple top pressure springs A40 will gradually decrease after prolonged use. Therefore, the present application provides the detachable plate 80, which is stacked and fixed at the bottom of the workpiece pressure plate 20. At this time, it can block multiple pressure holes 201 and support multiple heat-pressing columns 50, so that the multiple top pressure springs A40 are not stretched when not in use, thus better maintaining their elasticity and increasing their service life. Only when the present application is used can the fastening bolts 90 be screwed on to remove the detachable plate 80.

[0084] As described above, it is clear that by setting the detachable plate 80, this application can effectively protect the multiple top pressure springs A40, maintain their elasticity to increase their service life, and also protect the multiple heat-pressurizing columns 50 so that they are not damaged by external objects when not in use.

[0085] Therefore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.

[0086] Preferably, in this technical solution, the bottom of each of the multiple support blocks 301 is provided with screw holes 3011 facing upwards, and the periphery of the detachable plate 80 is provided with multiple fixing holes 801 penetrating its upper and lower end faces. The positions of the multiple fixing holes 801 are one-to-one with the positions of the multiple screw holes 3011. Multiple fastening bolts 90 are screwed into the multiple sets of fixing holes 801 and screw holes 3011 in the corresponding positions from bottom to top. In this way, the detachable plate 80 is fixedly attached to the bottom of the workpiece pressure plate 20.

[0087] Furthermore, in specific implementation, in accordance with... Figure 2 and Figure 4 As shown, according to one embodiment of the present invention, this application also includes a plurality of detachable seats 100;

[0088] Among them, multiple fixing slots 101 extend through the upper surface of the power plate 10, and multiple detachable seats 100 are detachably fixed in the multiple fixing slots 101; the upper ends of multiple top pressure springs A40 are connected to the multiple detachable seats 100.

[0089] Therefore, it can be clearly understood that when multiple detachable seats 100 are removed from the top of the power plate 10, multiple top pressure springs A40 and the multiple hot pressurizing columns 50 fixed at their bottoms are also removed to facilitate replacement or maintenance, thus making the overall performance of this application better.

[0090] Furthermore, according to an embodiment of the present invention, this application also includes a plurality of fixing blocks 110 and a plurality of pressure sensors 120;

[0091] The bottom of each of the detachable seats 100 is provided with an upward-facing receiving groove 1001; the fixing blocks 110 are respectively fixed between the upper ends of the multiple top pressure springs A40 and the bottoms of the multiple pressure sensors 120; the multiple pressure sensors 120 are respectively fixedly installed in the multiple receiving grooves 1001.

[0092] Therefore, by setting multiple pressure sensors 120, the pressure applied by multiple hot pressurizing columns 50 to multiple small workpieces can be detected accordingly. This allows for real-time monitoring of whether the pressure applied by a certain hot pressurizing column 50 to a certain small workpiece is too high or too low, so that operators can make timely adjustments.

[0093] Furthermore, in specific implementation, it is necessary to refer to... Figure 2 , Figure 4 and Figure 5 As shown, according to an embodiment of the present invention, each of the heat-pressurizing columns 50 includes a copper column 501, a heat insulation block 502, and an extension column 503.

[0094] The copper pillar 501, the heat insulation block 502, and the extension pillar 503 are connected sequentially from bottom to top; the lower ends of the multiple top pressure springs A40 are correspondingly connected to the upper parts of the multiple extension pillars 503.

[0095] As described above, it can be understood that, on the one hand, by setting the heat insulation block 502, this application provides heat insulation so that after the copper pillar 501 is heated, it can conduct heat downwards as much as possible to the multiple small workpieces it is pressed with, so that the multiple HAF adhesives set at the bottom of the multiple corresponding small workpieces are heated quickly and can melt rapidly. On the other hand, by setting the heat insulation block 502, this application provides isolation so that the multiple top pressure springs A40 and other components set on the upper part of the heat insulation block 502 are not easily deformed by heat, so that the multiple top pressure springs A40 and other components set on the upper part of the heat insulation block 502 have a long service life and stable performance.

[0096] Furthermore, in a specific implementation, according to an embodiment of the present invention, each of the copper pillars 501 has a heating channel extending into its interior on its sidewall, and a heating rod 5011 extending outward is fixed in each heating channel, and a temperature detection line 5012 is also connected outward to the sidewall of each copper pillar 501.

[0097] Therefore, it can be clearly stated that:

[0098] On the one hand, by connecting multiple heating rods 5011 to a heating component, the multiple copper pillars 501 can be heated separately. When they are heated independently, due to their small size, they are heated quickly as a whole. This allows the heat to be quickly conducted downwards to the multiple HAF adhesives at their bottom, ensuring that the multiple HAF adhesives are heated quickly and melted evenly, thus achieving a better melting effect quickly. This allows multiple corresponding small workpieces to be well hot-pressed and fixed.

[0099] On the other hand, by setting multiple temperature detection lines 5012 connected to an external main control device, the heating temperature of multiple copper pillars 501 can be detected in real time, so that the operator can know in real time whether the heating temperature of multiple copper pillars 501 has reached the specified requirements.

[0100] It should be added that, in a specific implementation, according to an embodiment of the present invention, a connecting seat 102 is provided in the middle of the upper end surface of the power plate 10; the connecting seat 102 is adapted to be connected to a lifting device, the lifting device being preferably a lifting cylinder, a cylinder drive linear module or a screw drive linear module.

[0101] Preferably, in this technical solution, each of the copper pillars 501 is made of beryllium copper with excellent thermal conductivity, and its outer surface is plated with a layer of precision chromium. The precision chromium plating coats the surface, which can better enhance the hardness and wear resistance of the multiple copper pillars 501 in this application, and can effectively prevent the oxidation of the surface to form verdigris that would contaminate the product.

[0102] Other embodiments, etc., will not be described here.

[0103] In summary, the multi-position heating and pressure-holding fixture 1000 provided in this application, in specific implementation, adopts a single-power multi-point heating and pressurizing method to heat and pressurize multiple small workpieces individually. This ensures that the multiple HAF adhesives corresponding to the bottom of the various small workpieces are uniformly melted, thus achieving a better heat-melting effect quickly. This allows the various small workpieces to be well-fixed by heat pressing. Furthermore, since the multiple heat-pressurizing columns 50 do not rigidly heat and pressurize the various small workpieces, the various small workpieces are not easily damaged by rigid force. At the same time, this application also has the function of individually detecting the downward pressure and the hot-pressing temperature of the multiple heat-pressurizing columns 50, making the overall performance of this application excellent.
