Abstract
Description
Technical Field
[0001] This invention relates to the field of automation equipment technology, and in particular to a multi-displacement heating pressure holding reverse jacking 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, lights and control buttons that make up smart devices to their back panels with hot melt adhesive.
[0003] In conventional pressing and fixing of two workpieces, a heating-function anti-top fixture is typically used to fix the larger workpiece. Then, hot melt adhesive is applied to the surface of the larger workpiece to bond multiple smaller workpieces together. Subsequently, a heating-function workpiece pressing fixture head is set above the anti-top fixture. As the workpiece pressing fixture head moves downward for a certain distance, it presses down on the multiple smaller workpieces for a certain duration. When the hot melt adhesive melts, the larger workpiece and the multiple smaller workpieces are pressed and fixed together. The anti-top fixture and the workpiece pressing fixture head together constitute a pressure-holding device.
[0004] The inventors of this patent discovered in their work that, for the aforementioned pressure-holding equipment and its related operating methods, it is necessary to first fix a large workpiece on a corresponding anti-top fixture, and then adhere multiple small workpieces to the upper surface of the large workpiece by applying hot melt adhesive. Subsequently, the corresponding workpiece pressing fixture head moves downwards for a certain stroke to press down the multiple small workpieces for a certain duration. During this process, when attaching multiple small workpieces, it is necessary to accurately locate their attachment positions in order to attach them precisely. Due to the large number of them, the actual operating efficiency is very low. Furthermore, the multiple attached small workpieces are directly pressed down without any auxiliary fixing parts to secure them, which makes it easy for the hot melt adhesive at the bottom to cause circumferential displacement when it melts.
[0005] 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.

[0105] The multi-displacement heating and pressure-holding anti-jacking fixture 1000 of the present invention is described in detail below with reference to the accompanying drawings.
[0106] Reference Figures 1 to 10 As shown, the multi-displacement heating and pressure-holding anti-top fixture 1000 provided according to an embodiment of the present invention includes a fixture base 10, a multi-workpiece clamping fixture platform 20, and multiple heating support columns 30 for heating the bottom of multiple workpieces respectively.
[0107] The multi-workpiece clamping fixture 20 includes a workpiece bearing plate 201 and a plurality of elastic clamps 202 for correspondingly clamping a plurality of workpieces; the workpiece bearing plate 201 is detachably fixed on the fixture base 10, and the middle part of its upper end surface is formed as a workpiece bearing surface, and the plurality of parts pressing positions on the workpiece bearing surface are respectively provided with limiting grooves 2011 downward, and the plurality of elastic clamps 202 are correspondingly installed in the plurality of limiting grooves 2011.
[0108] Furthermore, referring to Figure 2 and Figure 6 As shown, the workpiece bearing plate 201 has through openings 2012 on the sides of the multiple limiting grooves 2011, which penetrate the upper and lower end faces of the workpiece; the multiple heating support columns 30 are fixed on the fixture seat 10, and their upper ends extend upward from the multiple through openings 2012.
[0109] Based on the above, it is clear that in specific implementation, this application is mainly used as a multi-displacement heating pressure holding and counter-pressure jig 1000.
[0110] Specifically, when applying this application, the application is assembled according to the above structure. First, multiple small workpieces to be pressed are clamped and fixed in the multiple elastic clamps 202 at a preset fixed angle. Then, a hot melt adhesive is applied to the upper surface of each of the fixed small workpieces. Subsequently, a large workpiece is applied to the upper surface of the multiple hot melt adhesives. Finally, the corresponding large workpiece is pressed down for a certain period of time by the workpiece pressing jig head moving downward for a certain stroke. When the corresponding hot melt adhesive melts, the application can be combined to press and fix the corresponding large workpiece and multiple small workpieces together.
[0111] Regarding the above, it is clear that, in use, this application changes the traditional method of "small-to-large" (attaching multiple small workpieces to a large workpiece using multiple hot melt adhesive pieces) to "large-to-small" (attaching a large workpiece directly to multiple small workpieces using multiple hot melt adhesive pieces), which achieves the following technical effects:
[0112] Firstly, multiple small workpieces are pre-clamped and fixed at preset angles, ensuring good positioning and preventing displacement. Subsequently, when the corresponding large workpiece is pressed down for a certain duration by the downward movement of the matching workpiece pressing jig head, even if multiple pieces of corresponding hot melt adhesive melt, the large workpiece to be pressed is still firmly bonded by the multiple pieces of corresponding hot melt adhesive, making it difficult for the large workpiece to shift. Thus, even after using this application, the corresponding large workpiece and multiple small workpieces can be well pressed and fixed together.
[0113] Secondly, multiple small workpieces can be directly clamped and fixed at a preset fixed angle of 0 degrees using multiple elastic clamps 202. This operation is quick and time-saving, eliminating the need for manual positioning.
[0114] The fixed angle greatly reduces the fixing time for multiple small workpieces, thereby significantly improving the overall operating efficiency.
[0115] Furthermore, through the above-mentioned optimized design, this application replaces the traditional anti-top fixture for fixing large workpieces with a fixture for fixing multiple small workpieces. By using a large-to-small operation method, the large workpiece and multiple small workpieces are pressed together and fixed. This greatly shortens the fixing time of multiple small workpieces during use, and the fact that all the small workpieces are clamped and fixed makes them less prone to displacement. This makes the application highly practical and effective.
[0116] Furthermore, in specific implementation, refer to Figure 2 As shown, according to an embodiment of the present invention, the fixture base 10 includes a mounting base plate 101, a plurality of support blocks 102 and a plurality of guide posts 103; wherein, the plurality of support blocks 102 are uniformly fixed to the periphery of the upper end surface of the mounting base plate 101.
[0117] Multiple guide posts 103 are vertically fixed on the upper surfaces of multiple support blocks 102, and the outer diameter of the upper end of each guide post 103 is smaller than the outer diameter of its lower end.
[0118] Furthermore, the workpiece support plate 201 has a plurality of sleeve holes 2013 evenly opened around its periphery, penetrating its upper and lower end faces; the positions of the plurality of sleeve holes 2013 correspond to the positions of the plurality of guide posts 103, and the inner diameter of the plurality of sleeve holes 2013 is adapted to the lower outer diameter of the plurality of guide posts 103.
[0119] When the multiple guide posts 103 are inserted into the multiple sleeve holes 2013 with an interference fit, the workpiece bearing plate 201 is supported by the multiple support blocks 102.
[0120] As described above, it is clear that during actual installation, the workpiece support plate 201 described in this application is placed directly downwards from above the mounting base plate 101. When the multiple guide posts 103 are inserted into the multiple sleeve holes 2013 with an interference fit, it can be circumferentially fixed by the multiple guide posts 103 and supported by the multiple support blocks 102. This operation eliminates the need for fastening bolts. Furthermore, during this process, since the outer diameter of the upper end of the multiple guide posts 103 is smaller than the outer diameter of their lower end, and since the multiple... The inner diameter of each of the mounting holes 2013 is adapted to the outer diameter of the lower end of each of the guide posts 103. Therefore, when the workpiece bearing plate 201 is placed directly above the mounting base plate 101, the upper ends of each of the guide posts 103 can form guide portions, making it easy to pass through the mounting holes 2013. The lower ends of each of the guide posts 103 can also be inserted into the mounting holes 2013 with an interference fit. Thus, the workpiece bearing plate 201 described in this application is indeed not easy to shift circumferentially when it is installed and fixed.
[0121] Meanwhile, when the fixture base 10 described in this application includes a mounting base plate 101, multiple support blocks 102 and multiple guide columns 103, it also facilitates the easy disassembly of the workpiece bearing plate 201. Specifically, when it needs to be disassembled, it can be lifted upwards directly, and the related operation is simple and quick.
[0122] Furthermore, in specific implementation, we will continue to refer to... Figure 2 As shown, according to an embodiment of the present invention, each of the heating support columns 30 includes a heat-pressurizing column 301 and a heat insulation block 302 fixed at the bottom of the heat-pressurizing column 301.
[0123] The outer walls of the multiple heat-pressurizing columns 301 are respectively provided with heating channels extending into them, and a heating rod 3011 is fixedly installed outward in each heating channel. A temperature detection line 3012 is also fixedly installed on the outer wall of each heat-pressurizing column 301. The multiple heat insulation blocks 302 are all fixed on the upper surface of the mounting base plate 101.
[0124] Therefore, we can conclude that:
[0125] On the one hand, by connecting multiple heating rods 3011 to a heating component, the multiple hot pressurizing columns 301 can be heated separately. When they are all heated independently, due to their small size, they are heated quickly as a whole, and can quickly conduct heat upward to the multiple small workpieces fixed on the upper side, so that the multiple hot melt adhesives attached to the multiple small workpieces can be heated and melted quickly, so as to achieve a better heat melting effect quickly, so that the multiple corresponding small workpieces can be well hot-pressed and fixed to a large workpiece.
[0126] On the other hand, by setting multiple temperature detection lines 3012 connected to an external main control device, the heating temperature of multiple heating and pressurizing columns 301 can be detected in real time, so that the operator can know in real time whether the heating temperature of multiple heating and pressurizing columns 301 has reached the specified requirements.
[0127] Furthermore, by setting multiple heat insulation blocks 302 for heat insulation, the heat loss rate of the multiple heat pressurization columns 301 is also low, so that they can conduct heat upward as much as possible.
[0128] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.
[0129] Furthermore, in specific implementation, refer to Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, according to an embodiment of the present invention, each of the elastic clamps 202 includes a base plate 2021, an upper elastic clamp 2022 and multiple pressure-relieving springs A2023;
[0130] The bottom support plate 2021 has multiple guide rods 20211 facing upwards on its upper surface. Multiple pressure-relieving springs A2023 are correspondingly fixed outside the multiple guide rods 20211. The lower bottom surface of the upper elastic clip 2022 has multiple guide holes 2022a that are suitable for the upper ends of the multiple guide rods 20211 to pass through. The upper ends of the multiple pressure-relieving springs A2023 are correspondingly fixed outside the multiple guide holes 2022a.
[0131] As described above, it is clear that in a specific implementation of this application, the workpiece pressing jig head moves downward for a certain stroke to press down the corresponding large workpiece for a certain duration, and the corresponding large workpiece and multiple small workpieces are pressed and fixed together by the hot melt adhesive. The multiple pressure-relieving springs A2023 buffer the downward pressure, so that the large workpiece and multiple small workpieces to be pressed are not easily crushed or damaged, making this application safe and reliable to use.
[0132] Furthermore, in this technical solution, reference continues to be made to Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, according to an embodiment of the present invention, each of the upper elastic clamps 2022 includes a fixing block 20221, a plug-in block 20222, an L-shaped workpiece clamping member 20223, a fixing pin 20224, and a counter-rotating spring A20225;
[0133] The fixing blocks 20221 are respectively installed in the limiting grooves 2011. Each fixing block has a downward-facing insertion groove 202211 on its upper end face and a movable groove A202212 on its inner end face that connects to the insertion groove 202211 and extends to its outer end face. The plugging blocks 20222 are respectively snapped into the insertion grooves 202211. Each plugging block has a movable groove B202221 that extends through its inner and outer end faces and a locking groove 202222 that extends through its upper and lower end faces. The movable grooves B202221 and A202212 have the same inner diameter and are coaxially arranged. The locking grooves B202222 are respectively connected to the movable grooves B202221.
[0134] Furthermore, each of the multiple L-shaped workpiece clamping components 20223 includes a vertically arranged clamping block 202231 and a movable rod 202232 vertically connected to the lower part of the clamping block 202231; the connecting ends of the multiple movable rods 202232 are respectively provided with spring slots 2022321 extending to their ends, and the upper surfaces of the multiple movable rods 202232 are respectively provided with spring-loaded grooves 2022322 communicating with the spring slots 2022321 on them near their connecting ends; the inner and outer distances of the multiple spring-loaded grooves 2022322 are all greater than the outer diameter of the multiple fixing pins 20224;
[0135] Simultaneously, multiple movable rods 202232 are inserted into multiple movable slots A202212 and B202221 from the inside out, with their ends extending out of the outer ends of the multiple movable slots A202212; multiple fixing pins 20224 are inserted into multiple locking slots 202222, with their lower ends extending into multiple spring slots 2022321; and multiple anti-top springs A20225 are inserted into multiple spring slots 022321, with their inner ends abutting against the outer walls of the multiple fixing pins 20224.
[0136] Initially, all of the multiple anti-top springs A20225 are in a natural or compressed state, the lower outer walls of the multiple fixing pins 20224 abut against the inner ends of the multiple spring pressure grooves 2022322, and the outer end faces of the multiple clamping blocks 202231 abut against the inner end faces of the multiple fixing blocks 20221.
[0137] Therefore, when the ends of the multiple movable rods 202232 are pressed inward, the multiple anti-top springs A20225 can be further compressed. At this time, the outer end faces of the multiple clamping blocks 202231 will be respectively away from the inner end faces of the multiple fixing blocks 20221, and the gap between the outer end faces of the multiple clamping blocks 202231 and the inner end faces of the multiple fixing blocks 20221 can be used to clamp multiple small workpieces.
[0138] Subsequently, by releasing the ends of the multiple movable rods 202232, the multiple anti-top springs A20225 will automatically extend. At this time, the outer end faces of the multiple clamping blocks 202231 will approach the inner end faces of the multiple fixing blocks 20221, thus enabling the clamping of multiple small workpieces so that all the small workpieces can be clamped and fixed.
[0139] It should be noted that, since the multiple upper elastic clamps 2022 described in this application are all for elastically clamping small workpieces, their clamping gap (the gap between the outer end faces of the multiple clamping blocks 202231 and the inner end faces of the multiple fixing blocks 20221) can be flexibly and adaptively changed according to the size of the small workpiece, making the multiple upper elastic clamps 2022 described in this application highly flexible and adaptable in use.
[0140] Furthermore, regarding the upper elastic clip 2022 of the aforementioned structure, on the one hand, when the multiple anti-top springs A20225 are correspondingly inserted into the multiple spring slots 2022321, and their inner ends abut against the outer walls of the multiple fixing pins 20224, the multiple anti-top springs A20225 are not easily dislodged, and their locking and limiting properties are good, making them stable and reliable in use. This also makes the multiple upper elastic clips 2022 of this application stable and reliable in use. On the other hand, when the multiple fixing pins 20224 are removed, the multiple anti-top springs can be easily disassembled. The A20225, multiple L-shaped workpiece clamping parts 20223, and multiple plug-in blocks 20222 facilitate disassembly and replacement when multiple anti-top springs A20225 fail. Conversely, when multiple anti-top springs A20225, multiple L-shaped workpiece clamping parts 20223, multiple plug-in blocks 20222, and multiple fixing pins 20224 are fixed in sequence, it also facilitates the quick installation of multiple upper elastic clips 2022 of this application. Thus, the multiple upper elastic clips 2022 of this application are quick and convenient to assemble and disassemble.
[0141] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be further improved.
[0142] Furthermore, based on the above, this technical solution still refers to... Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, according to an embodiment of the present invention, the bottom surface of the fixing block 20221 is provided with a plurality of guide holes 2022a, which are suitable for the upper ends of the multiple guide rods 20211 to pass through.
[0143] Furthermore, in a specific implementation, according to an embodiment of the present invention, each of the upper elastic clips 2022 also includes a slider 20226 fixed to the bottom of the fixed block 20221;
[0144] Each of the limiting grooves 2011 has a slide rail 20111 fixedly mounted on its bottom facing the center of the workpiece bearing surface; a plurality of sliders 20226 are correspondingly engaged on the outside of the plurality of slide rails 20111; the inner ends of each limiting groove 2011 protrude from both sides toward the center to form a limiting protrusion 20112, and the outer ends are respectively detachably equipped with stop blocks 20113;
[0145] Therefore, when the multiple fixing blocks 20221 are installed in the multiple limiting grooves 2011, their inner and outer sides are limited by multiple sets of two limiting protrusions 20112 and multiple sets of two stop blocks 20113.
[0146] Furthermore, when the multiple sets of two stop blocks 20113 are removed, the installation of multiple fixing blocks 20221 is facilitated. Then, the multiple sets of two stop blocks 20113 are re-fixed, which limits the installation of multiple fixing blocks 20221, making it convenient to install and remove multiple fixing blocks 20221.
[0147] Secondly, in specific implementation, refer to Figure 5 As shown, according to an embodiment of the present invention, each of the two limiting protrusions 20112 in each group is provided with a counter-spring B20114 that elastically abuts against the inner end face of the fixing block 20221 installed in the corresponding limiting groove 2011.
[0148] Initially, all of the aforementioned anti-top springs B20114 are in a natural or compressed state, and the outer sides of the aforementioned fixing blocks 20221 abut against the inner end faces of the aforementioned two sets of stop blocks 20113.
[0149] Therefore, by setting multiple anti-top springs B20114 to press against multiple fixing blocks 20221, the multiple fixing blocks 20221 are all fixed and stable.
[0150] It should be noted that the reason for fixing the multiple fixing blocks 20221 according to the above-described structure (by setting slide rail 20111, slider 20226 and anti-top spring B20114) is that when actually pressing and fixing a large workpiece and multiple small workpieces, the multiple fixing blocks 20221 need to have a certain downward stroke in the vertical direction. That is, this application uses multiple pressure relief springs A2023 to drive them to have a certain downward stroke in the vertical direction. In other words, the multiple fixing blocks 20221 in this application cannot be fixed in the vertical direction, so they cannot be fixed in place by fastening bolts or other components.
[0151] Preferably, according to an embodiment of the present invention, each set of two limiting protrusions 20112 has a locking groove A201121 on its inner end face, and each fixing block 20221 has two locking grooves B202213 on its inner end face, which are respectively opposite to the positions of the two locking grooves A201121; the inner and outer ends of the multiple anti-top springs B20114 are correspondingly locked in the multiple sets of locking grooves A201121 and locking grooves B202213 at the relative positions.
[0152] Therefore, by setting multiple sets of locking grooves A201121 and B202213 with opposite positions to correspondingly lock the multiple anti-reverse springs B20114, the multiple anti-reverse springs B20114 are all used with good stability, making them less likely to bounce off, making the application safer and more reliable to use.
[0153] It should be added that, in specific implementation, comparison should be made with... Figure 1 , Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, this application also includes a plurality of push cylinders A40 for correspondingly pushing a plurality of the bottom support plates 2021 and a plurality of push cylinders B50 for correspondingly pushing a plurality of the movable rods 202232.
[0154] Among them, multiple push cylinders A40 are evenly fixed around the upper end surface of the mounting base plate 101, and their cylinder rods A401 abut against the outer end surfaces of multiple base plates 2021 to push multiple elastic clamps 202 to move inward along multiple slide rails 20111.
[0155] Furthermore, multiple push cylinders B50 are stacked and fixed on the upper end face of multiple push cylinders A40, and their cylinder rods B501 abut against the outer end face of multiple movable rods 202232 to drive multiple upper elastic clamps 2022 to open accordingly.
[0156] Based on the above, it should be noted that:
[0157] On the one hand, the fixed position of different small workpieces is not constant. Therefore, this application sets up multiple push cylinders A40 to push multiple bottom support plates 2021, so that multiple elastic clamps 202 can move inward along multiple slide rails 20111. The stroke of their inward movement along multiple slide rails 20111 can be independently controlled, so that the inner and outer positions of the multiple small workpieces clamped and fixed on the multiple elastic clamps 202 can be flexibly adjusted, enabling this application to... This system enables multiple workpieces to be clamped and fixed in multiple displacements. After the multiple workpieces are clamped and fixed and all have been displaced to the appropriate position, they are counter-pressed by multiple counter-pressing springs B20114. This ensures that the multiple elastic clamps 202 are not easily displaced, and that the multiple small workpieces clamped and fixed thereon are well fixed. Furthermore, the multiple push cylinders A40 are used to push the multiple elastic clamps 202 to move inward along the multiple slide rails 20111. The related operations are intelligent and automated, which greatly saves manpower.
[0158] On the other hand, this application sets up multiple push cylinders B50 to push the outer end faces of multiple movable rods 202232, so that multiple upper elastic clamps 2022 can be driven to open accordingly, so as to place the small workpiece to be hot-pressed and fixed inside. The related operation is also intelligent and automated, which can greatly save manpower.
[0159] Furthermore, through the above-mentioned optimized design, the overall performance of this application is even better.
[0160] It should be added that, in specific implementation, comparison should be made with... Figure 4 , Figure 7 and Figure 8 As shown, according to one embodiment of the present invention, the multi-workpiece clamping fixture 20 further includes a workpiece support plate 203 with poor thermal conductivity;
[0161] In this case, a groove 2014 is provided downward on the area of the workpiece bearing surface that is not the limiting groove 2011. The workpiece support plate 203 is fixed in the groove 2014 with an interference fit, and its upper end face is flush with the upper end face of the workpiece bearing surface.
[0162] It should be noted that when using this application, when the workpiece pressing jig head moves downward for a certain stroke to press down the corresponding large workpiece for a certain period of time, it will also have a heating function to conduct heat to the fixed large workpiece, and then the fixed large workpiece will conduct heat to multiple pieces of hot melt adhesive to promote its heat melting.
[0163] It should also be noted that the area of the workpiece bearing surface that is not the limiting groove 2011 is the non-part pressing area. The area occupied by the relevant non-part pressing area is basically greater than the sum of the multiple part pressing areas, that is, greater than the sum of the areas where the multiple limiting grooves 2011 are located corresponding to the multiple part pressing positions. This non-part pressing area does not require too much heat.
[0164] Therefore, on the one hand, in order to avoid heat loss and improve heat conduction efficiency, this application provides a downward groove 2014 in the area of the workpiece bearing surface other than the limiting groove 2011. In this way, the area of the entire workpiece bearing surface that needs to conduct heat can be greatly reduced, so that the fixed large workpiece can quickly conduct heat to the multiple pieces of hot melt adhesive to promote rapid heat melting, thereby effectively improving the entire heating and pressure holding process of the product. On the other hand, by fixing the workpiece support plate 203 in the groove 2014 with an interference fit, and making its upper end face flush with the upper end face of the workpiece bearing surface, the purpose of this is to ensure that the entire workpiece bearing surface of this application can still support the fixed large workpiece very flat. When the fixed large workpiece is pressed down by the workpiece pressing jig head, its bottom non-part pressing area can also be supported, so that its bottom non-part pressing area is not easily deformed by the pressure, resulting in collapse or cracking, thus making the protection performance of product quality of this application better.
[0165] Preferably, in this technical solution, according to an embodiment of the present invention, the multi-workpiece clamping fixture 20 further includes multiple pressure-relieving springs B204;
[0166] Among them, multiple pressure-relieving springs B204 are evenly fixed vertically on the bottom surface of the inner side of the support groove 2014, and their upper ends all abut against the bottom surface of the workpiece support plate 203.
[0167] As described above, it can be understood that when the large workpiece is pressed down by the workpiece pressing jig head, the non-part pressing area on its bottom surface is supported and lifted. In addition, this application uses multiple pressure-relieving springs B204 to buffer the downward pressure, so that the non-part pressing area of the large workpiece that needs to be pressed is not easily crushed or damaged. This makes the safety and reliability of this application reach the best level, and the control of product quality also reaches the best level.
[0168] Furthermore, through the aforementioned optimized design, the entirety constituted by this application indeed has excellent performance, ensuring that this application will inevitably be promoted and applied.
[0169] Furthermore, in specific implementations of this application, since the multi-workpiece clamping fixture 20 can be easily detached from the fixture base 10, it can be directly used as a small workpiece carrier for material transfer. In other words, the multi-workpiece clamping fixture 20 of this application can be used independently as a material tray. Specifically, when using this application, multiple small workpieces to be pressed can be pre-installed on the workpiece bearing plate 201 of the multi-workpiece clamping fixture 20, and multiple multi-workpiece clamping fixtures 20 with the small workpieces to be pressed can be prepared. Each time this application is used... When applying, the multi-workpiece clamping fixture 20, which is equipped with small workpieces that need to be pressed, can be directly installed and fixed onto the fixture base 10. Then, it can be used in conjunction with the workpiece pressing fixture head. After the workpiece is pressed and fixed, the used multi-workpiece clamping fixture 20 is removed, and a new multi-workpiece clamping fixture 20 equipped with multiple small workpieces that need to be pressed is fixed on the corresponding fixture base 10. This cycle is repeated, so that it is not necessary to temporarily install multiple small workpieces, making the application more flexible in use.
[0170] Other embodiments, etc., will not be described here.
[0171] In summary, the multi-displacement heating and pressure-holding anti-top fixture 1000 provided by the present invention can elastically clamp multiple small workpieces to be pressed and fixed according to a preset fixing angle during specific implementation. Compared with the prior art, the fixing time of multiple small workpieces can be greatly shortened. The clamping and fixing of multiple small workpieces also makes them less prone to displacement. Furthermore, after multiple small workpieces are clamped and fixed, their positions can be flexibly adjusted according to actual needs, making this application truly practical and achieving the best results.
