Description

Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to an assembly pressing machine. Background Technology

[0002] During machining operations, it is necessary to press one part onto another part. In order to ensure the stability of the connection after pressing, glue is usually applied to the joint between the two parts.

[0003] There is an issue of glue overflow during pressing operations. When the pressing head presses against small parts, glue gets on the pressing head. Since the pressing head temperature is 180°C, manual cleaning is time-consuming and laborious, greatly increasing the machine's CT time. Moreover, the high-temperature pressing head can easily burn operators, and manual glue cleaning poses a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an assembly and pressing machine with high stability and safety.

[0005] The objective of this invention can be achieved through the following technical solutions: An assembly pressing machine includes a frame with a working platform on the upper part of the frame. The working platform has a main board module for placing workpieces to be pressed. The machine is characterized by further including a scanning component, a driving component, and a pressing assembly. When the workpiece to be pressed is placed on the main board module, the scanning component scans an identification code on the workpiece. Initially, the pressing assembly is away from the main board module. When the scanning component detects that the corresponding workpiece is located on the main board module, the driving component moves the pressing assembly to the main board module, and the pressing assembly performs pressing operations on the pressing portion of the workpiece.

[0006] In the above-mentioned assembly pressing machine, the pressing component includes a slider and a pressing part connected to the slider. The working platform has a horizontally arranged guide rail, the slider is connected to the guide rail, and the driving component is fixed to the working platform and connected to the slider.

[0007] In the above-mentioned assembly pressing machine, a limiting block is fixedly connected to the working platform and is directly opposite the slider. The limiting block has a buffer. When the slider abuts against the buffer, the pressing part on the slider is located directly above the motherboard module.

[0008] In the aforementioned assembly and pressing machine, the pressing section includes a substrate, a film strip, a take-up roller, a feed roller, a guide roller assembly, a tension roller assembly, a hot press component, and a second driving component. The substrate is flat and fixed to the slider. The take-up roller and the feed roller are both connected to the upper part of the substrate and are adjacent to each other on the left and right. The guide roller assembly is connected to the substrate and is located directly below the take-up roller. The tension roller assembly is connected to the substrate and is located directly below the feed roller. One end of the film strip is connected to the feed roller, and the other end of the film strip is connected to the take-up roller. The middle part of the film strip is wound around the guide roller assembly and the tension roller assembly in sequence. The film strip between the guide roller assembly and the tension roller assembly is the pressing section. In the initial state, the hot press component is located above the pressing section. When the second driving component moves the hot press component downward, the hot press component can push the pressing section to the main board module.

[0009] In the above-mentioned assembly and pressing machine, the guide roller assembly includes roller one, roller two and a correction component movably connected to the substrate. Roller one is located in the middle of the substrate, roller two is located in the lower part of the substrate, and the correction component is located between roller one and roller two. The film strip is wound around roller one and roller two in sequence, and the film strip between roller one and roller two passes through the correction component.

[0010] In the above-mentioned assembly and pressing machine, the correction component includes a correction wheel one, a correction wheel two, and a swing rod one. The correction wheel one has protruding baffles on both sides. The middle part of the swing rod one is hinged to the base plate. The correction wheel two is connected to the outer end of the swing rod one. There is a pre-tightening member between the base plate and the outer end of the swing rod one. Under the action of the pre-tightening member, the inner end of the swing rod one swings downward and the correction wheel two tends to abut against the correction wheel one. The correction wheel two abuts against one side of the correction wheel between the two baffles.

[0011] In the aforementioned assembly and pressing machine, the preload component is a hydraulic damper.

[0012] In the above-mentioned assembly and pressing machine, the tensioning component includes rollers three, four and five movably connected to the substrate. Rollers three, four and five are arranged from top to bottom. Roller four is located on the side between the line connecting rollers three and five. The film strip is wound around rollers three, four and five in sequence.

[0013] The assembly and pressing machine described above also includes a swing arm two, the inner end of which is hinged to the substrate, and the roller four is movably connected to the outer end of the swing arm two. There is a torsion spring between the swing arm two and the substrate. Under the elastic force of the torsion spring, the roller four at the outer end of the swing arm two tends to press tightly onto the film belt.

[0014] In the above-mentioned assembly and pressing machine, the hot pressing component includes a second driving component, a pressing block, a heating rod, and a counterweight. The base plate has a second vertically arranged guide rail. The pressing block is connected to the second guide rail. The heating rod is connected inside the pressing block. The second driving component is fixed to the base plate and connected to the pressing block. The counterweight is detachably connected to the upper part of the pressing block.

[0015] Compared to existing technologies, this assembly and pressing machine uses a film belt and a servo motor and rotary damper to precisely control the rotation of the take-up and unload rollers, achieving the film belt winding function. The guide roller assembly is responsible for guiding the film belt, preventing excessive winding or deviation. The tension roller assembly uses the elasticity of torsion springs to ensure the tension of the entire film belt. This prevents the film belt from becoming loose during the next pressing, which would result in the film belt not being accurately positioned under the pressure head. Conversely, this solution ensures that the film belt stably protects the pressing block during pressing operations, and adhesive is less likely to stick to the pressure head.

[0016] The overflowing glue will be steadily carried away by the membrane belt.

[0017] Meanwhile, the pressing block uses a counterweight for pressing, eliminating the need for cylinder force. The cylinder is only responsible for lifting the pressing head. When pressing small parts, the counterweight itself presses the small parts and the product together, resulting in a more stable pressing effect. The pressing force is not affected by external forces.

[0018] As can be seen, the entire pressing machine can prevent residual glue from overflowing onto the workpiece during the pressing operation, effectively improving the quality of the finished product. Furthermore, since there is no need to clean the high-temperature pressing blocks, the operation is also relatively safe. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should be noted that when a component is said to be "mounted on" another component, it can be directly mounted on the other component or may be interspersed with a component. When a component is said to be "set on" another component, it can be directly set on the other component or may be interspersed with a component. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or may be interspersed with a component.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5As shown, this assembly pressing machine includes a frame 1, with a working platform 2 on the upper part of the frame 1. The working platform 2 has a main board module 3 for placing the workpiece to be pressed. It also includes a scanning component 4, a driving component 5, and a pressing assembly. When the workpiece to be pressed is placed on the main board module 3, the scanning component 4 can scan the identification code on the workpiece. In the initial state, the pressing assembly is away from the main board module 3. When the scanning component 4 detects that the corresponding workpiece to be pressed is located on the main board module 3, the driving component 5 can drive the pressing assembly to move to the main board module 3. The pressing assembly can then perform pressing operations on the pressing part of the workpiece to be pressed.

[0029] Scanner 4 is used to scan the workpiece placed on the motherboard module 3, thereby facilitating the verification and recording of the processing operation.

[0030] Once the workpiece to be pressed is placed in place, the drive component 5 drives the pressing assembly into the main board module 3, and the pressing assembly then performs the workpiece pressing operation.

[0031] Of course, after the workpiece pressing process is completed, the drive component 5 drives the pressing assembly to exit.

[0032] In this embodiment, dampers are provided at both the take-up roller 12 and the unwind roller 13 to precisely control the release and rewinding of the film strip.

[0033] The pressing assembly includes a slider 6 and a pressing part connected to the slider 6. The working platform 2 has a horizontally arranged guide rail 7. The slider 6 is connected to the guide rail 7. The driving component 5 is fixed to the working platform 2 and is connected to the slider 6.

[0034] Since the slider 6 is connected to the guide rail 7, the entire pressing assembly can be stably translated relative to the motherboard module 3 under the action of the drive component 5.

[0035] Ultimately, this ensures that the pressing assembly can switch stably between working and non-working states.

[0036] A limiting block 8 is fixedly connected to the working platform 2, which is directly opposite to the slider 6. The limiting block 8 has a buffer 9. When the slider 6 abuts against the buffer 9, the pressing part on the slider 6 is located directly above the motherboard module 3.

[0037] The movement of slider 6 is limited by limit block 8, ensuring that the pressing component is stably positioned on the upper part of motherboard module 3 during operation. Meanwhile, buffer 9 prevents slider 6 from rigidly contacting the motherboard, effectively reducing noise and ensuring stability.

[0038] Buffer 9 is an existing damping buffer; therefore, the specific technical features of buffer 9 will not be described in detail in the embodiments.

[0039] The pressing section includes a substrate 10, a film belt 11, a take-up roller 12, a feed roller 13, a guide roller assembly, a tension roller assembly, a hot pressing component, and a driving component 14. The substrate 10 is flat and fixed to the slider 6. The take-up roller 12 and the feed roller 13 are both connected to the upper part of the substrate 10 and are adjacent to each other on the left and right. The guide roller assembly is connected to the substrate 10 and is located directly below the take-up roller 12. The tension roller assembly is connected to the substrate 10. The tensioning wheel assembly is located directly below the feeding wheel 13. One end of the film belt 11 is connected to the feeding wheel 13, and the other end of the film belt 11 is connected to the receiving wheel 12. The middle part of the film belt 11 is wrapped around the guide wheel assembly and the tensioning wheel assembly in sequence. The film belt 11 between the guide wheel assembly and the tensioning wheel assembly is the pressing section. In the initial state, the hot pressing component is located above the pressing section. When the driving component 2 14 drives the hot pressing component to move down, the hot pressing component can push the pressing section to the main board module 3.

[0040] The two ends of the membrane belt 11 are connected to the feeding wheel 13 and the receiving wheel 12 respectively. At the same time, the membrane belt 11 is wound around the guide wheel assembly and the tensioning wheel assembly in sequence. Therefore, the continuous rotation of the receiving wheel 12 and the feeding wheel 13 can drive the membrane belt 11 to move stably.

[0041] Each time the hot-pressing component is pressed down, the membrane belt 11 moves intermittently by a set distance to ensure that a new membrane belt 11 contacts the workpiece to be pressed each time the hot-pressing is performed.

[0042] Excess adhesive that overflows from the workpiece to be pressed adheres to the membrane tape 11. To prevent excess adhesive residue from remaining on the workpiece, in this embodiment, the membrane tape 11 is made of PI material (polyimide).

[0043] The film strip 11 with adhesive residue eventually enters the receiving wheel 12, where the film strip 11 with adhesive residue is collected.

[0044] The guide roller assembly includes a first roller 15, a second roller 16, and a correction component movably connected to the substrate 10. The first roller 15 is located in the middle of the substrate 10, the second roller 16 is located in the lower part of the substrate 10, and the correction component is located between the first roller 15 and the second roller 16. The film strip 11 is sequentially wound around the first roller 15 and the second roller 16, and the film strip 11 between the first roller 15 and the second roller 16 passes through the correction component.

[0045] The corrective assembly can stabilize and level the film belt 11 between roller 15 and roller 26, preventing the film belt 11 from bending when it enters the take-up roller 12.

[0046] The correction assembly includes a correction wheel 17, a correction wheel 18, and a swing arm 19. The correction wheel 17 has protruding baffles 17a on both sides. The swing arm 19 is hinged to the base plate 10 in the middle. The correction wheel 18 is connected to the outer end of the swing arm 19. A pre-tightening member 21 is provided between the base plate 10 and the outer end of the swing arm 19. Under the action of the pre-tightening member 21, the inner end of the swing arm 19 swings downward and the correction wheel 18 tends to abut against the correction wheel 17. The correction wheel 18 abuts against the side of the correction wheel 17 between the two baffles 17a.

[0047] The membrane belt 11 is positioned on the first correction wheel 17 between the two baffles 17a. At the same time, the second correction wheel 18 tends to abut against the side of the first correction wheel 17 between the two baffles 17a. Therefore, the membrane belt 11 passing through the first correction wheel 17 and the second correction wheel 18 will be stably leveled.

[0048] The preload 21 is a hydraulic damper.

[0049] The tensioning assembly includes rollers 22, 23, and 24 movably connected to the substrate 10. The rollers 22, 23, and 24 are arranged from top to bottom. The roller 23 is located on the side between the line connecting rollers 22 and 24. The film strip 11 is wound around the rollers 22, 23, and 24 in sequence.

[0050] Since the membrane belt 11 is wound sequentially around rollers 22, 23, and 24, it can be appropriately tensioned under the action of these rollers. Of course, since this section of the membrane belt 11 has just been released from the feed roller 13, it will not bend at this point. The membrane belt 11 can only bend after being deformed by the hot press; therefore, the guide roller assembly is positioned adjacent to the take-up roller 12.

[0051] It also includes a swing arm 25, the inner end of which is hinged to the frame 1, and the roller 23 is movably connected to the outer end of the swing arm 25. There is a torsion spring 26 between the swing arm 25 and the substrate 10. Under the elastic force of the torsion spring 26, the roller 23 at the outer end of the swing arm 25 tends to press tightly onto the film belt 11.

[0052] The second 25 of the lever has two functions: Firstly, under the action of the torsion spring 26, the roller 23 can have a tendency to swing; Secondly, provide sufficient space for the connection of roller 423.

[0053] The hot pressing component includes a pressing block 28, a heating rod 29, and a counterweight 30. The base plate 10 has a vertically arranged guide rail 31. The pressing block 28 is connected to the guide rail 31. The heating rod 29 is connected inside the pressing block 28. The driving component 14 is fixed to the base plate 10 and connected to the pressing block 28. The counterweight 30 is detachably connected to the upper part of the pressing block 28.

[0054] In this embodiment, the heating rod 29 is an electric heating rod, which can stably increase the temperature of the pressed block after being energized. In this embodiment, the temperature of the pressed block after the temperature increase is 180 degrees Celsius.

[0055] The driving component 14 is a cylinder. In the initial state, the piston rod of the cylinder pushes against the pressure block 28 and causes the pressure block 28 to tend to move away from the main board module 3. Once the piston of the cylinder retracts, the pressure block 28 pushes the film belt 11 under its own gravity and makes it contact the workpiece to be pressed.

[0056] It can be seen that the counterweight 30 increases the weight of the pressing block, ensuring that the pressing block 28 has sufficient pressure on the workpiece to be pressed. Since the counterweight 30 is detachably connected to the pressing block 28, it can be replaced or added or removed according to the actual situation to adapt to different pressing operation requirements.

[0057] The motherboard module is an existing positioning fixture. Different motherboard modules are used for different products to be pressed. The problem that this patent application needs to solve is how to perform hot pressing on the product. As for which positioning fixture the product is connected to, that is, how the product is connected to the motherboard module, that is prior art, and this part of the technical solution is not the technical problem that this patent application needs to solve. Therefore, the technical features of the motherboard module will not be described in the embodiments.

[0058] This assembly press uses a film belt and a servo motor and rotary damper to precisely control the rotation of the take-up and unload rollers, achieving the film belt winding function. The guide roller assembly is responsible for guiding the film belt, preventing excessive winding or deviation. The tension roller assembly uses the elasticity of torsion springs to ensure the tension of the entire film belt. This prevents the film belt from becoming loose during the next press, which would make it difficult to accurately position the film belt under the press head. Conversely, this design ensures that the film belt stably protects the press block during the pressing operation, and glue does not easily stick to the press head.

[0059] The overflowing glue will be steadily carried away by the membrane belt.

[0060] Meanwhile, the pressing block uses a counterweight for pressing, eliminating the need for cylinder force. The cylinder is only responsible for lifting the pressing head. When pressing small parts, the counterweight itself presses the small parts and the product together, resulting in a more stable pressing effect. The pressing force is not affected by external forces.

[0061] As can be seen, the entire pressing machine can prevent residual glue from overflowing onto the workpiece during the pressing operation, effectively improving the quality of the finished product. Furthermore, since there is no need to clean the high-temperature pressing blocks, the operation is also relatively safe. The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
