Description

Technical Field

[0001] The invention belongs to the technical field of machinery and relates to an assembling pressing machine. Background Art

[0002] During the machining process, one part needs to be pressed onto another part. In order to ensure the stability of the connection after pressing, glue is usually applied to the connection between the two parts.

[0003] There is a problem of glue overflow during the pressing operation. When the pressing head is pressed with small parts, glue will stick to the pressing head. Since the temperature of the pressing head is 180°, manual cleaning is time-consuming and laborious, which greatly increases the CT time of the machine. In addition, the high-temperature pressing head can easily burn the operator, and manual glue cleaning poses a safety hazard. Summary of the invention

[0004] The purpose of the present invention is to provide an assembly press machine with relatively high stability and safety in view of the above problems existing in the prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions: An assembly pressing machine comprises a frame, a working platform is provided on the upper part of the frame, a mainboard module is provided on the working platform for placing workpieces to be pressed, and the machine is characterized in that it also comprises a scanning component, a driving component and a pressing component. When the workpiece to be pressed is placed on the mainboard module, the scanning component can scan the identification code on the workpiece to be pressed, and the pressing component is away from the mainboard module in the initial state. When the scanning component detects that the corresponding workpiece to be pressed is located at the mainboard module, the driving component can drive the pressing component to move to the mainboard module, and the pressing operation can be performed on the pressing part of the workpiece to be pressed through the pressing component.

[0006] In the above-mentioned assembly pressing machine, the pressing assembly includes a slider and a pressing part connected to the slider, the above-mentioned working platform has a transversely arranged guide rail one, the above-mentioned slider is connected to the guide rail one, the above-mentioned driving member one is fixedly connected to the working platform and the driving member one is connected to the slider.

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

[0008] In the above-mentioned assembly pressing machine, the pressing part includes a substrate, a film tape, a material collection wheel, a material discharge wheel, a guide wheel assembly, a tension wheel assembly, a hot pressing part and a driving part 2. The above-mentioned substrate is in the shape of a flat plate and is fixedly connected to a slider. The above-mentioned material collection wheel and the material discharge wheel are both connected to the upper part of the substrate and are adjacent to each other on the left and right. The above-mentioned guide wheel assembly is connected to the substrate and the guide wheel assembly is located directly below the material collection wheel. The above-mentioned tension wheel assembly is connected to the substrate and the tension wheel assembly is located directly below the material discharge wheel. One end of the above-mentioned film tape is connected to the material discharge wheel, and the other end of the film tape is connected to the material collection wheel. The middle part of the film tape is sequentially wound around the guide wheel assembly and the tension wheel assembly. The film tape between the guide wheel assembly and the tension wheel assembly is a pressing section. In the initial state, the hot pressing part is located above the pressing section. When the driving part 2 drives the hot pressing part downward, the hot pressing part can push the pressing section to the main board module.

[0009] In the above-mentioned assembly and pressing machine, the guide wheel assembly includes roller one, roller two and a correction assembly movably connected to the base plate, roller one is located in the middle of the base plate, roller two is located at the lower part of the base plate, the correction assembly is located between roller one and roller two, the film tape is sequentially wound around roller one and roller two, and the film tape between roller one and roller two is passed through the correction assembly.

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

[0011] In the above-mentioned assembly press, the pre-tightening member is an oil pressure buffer.

[0012] In the above-mentioned assembly pressing machine, the tensioning assembly includes roller three, roller four and roller five movably connected to the base plate, the above-mentioned roller three, roller four and roller five are arranged from top to bottom, the above-mentioned roller four is located at the side between the line connecting roller three and roller five, and the above-mentioned film tape is wound around roller three, roller four and roller five in sequence.

[0013] The above-mentioned assembly pressing machine also includes a rocker arm 2, the inner end of which is hinged on the base plate, and the roller 4 is movably connected to the outer end of the rocker arm 2. A torsion spring is provided between the rocker arm 2 and the base plate. Under the elastic force of the torsion spring, the roller 4 at the outer end of the rocker arm 2 tends to be pressed tightly against the film strip.

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

[0015] Compared with the existing technology, this assembly press machine uses film tape and uses servo motors and rotary dampers to accurately control the rotation of the take-up wheel and the unwinding wheel, realizing the film tape winding function. The guide wheel assembly is responsible for guiding the film tape to prevent the film from being rolled up or deviating too much. The tension wheel assembly uses the elastic force of the torsion spring to ensure the tension of the entire film tape. It prevents the film tape from having no tension, causing the film tape to become loose during the next pressing, and the film tape cannot be accurately positioned under the pressure head. On the contrary, this solution can ensure that the film tape stably protects the pressing block during the pressing operation, and the glue is not easy to stick to the pressure head.

[0016] The overflowing glue will be stably carried away by the film tape.

[0017] At the same time, the pressing block uses a counterweight block to press, and the cylinder force is cancelled. The cylinder is only responsible for lifting the pressure head. When pressing small parts, the counterweight block relies on its own gravity to press small parts and products, so the pressing effect is more stable. The pressing force is not affected by external factors.

[0018] It can be seen that the entire pressing machine can avoid residual glue overflow on the workpiece during the pressing operation, effectively improving the quality of the finished product. And because there is no need to clean the relatively high temperature pressing block, the operation safety is also relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly mounted on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0028] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5As shown, the assembly pressing machine includes a frame 1, the upper part of the frame 1 is provided with a working platform 2, the working platform 2 is provided with a mainboard module 3 for placing the workpiece to be pressed, and also includes a scanning component 4, a driving component 5 and a pressing component. When the workpiece to be pressed is placed on the mainboard module 3, the scanning component 4 can scan the identification code on the workpiece to be pressed, and the pressing component is away from the mainboard module 3 in the initial state. When the scanning component 4 detects that the corresponding workpiece to be pressed is located at the mainboard module 3, the driving component 5 can drive the pressing component to move to the mainboard module 3, and the pressing operation can be performed on the pressing part of the workpiece to be pressed through the pressing component.

[0029] The scanning part 4 is used to scan the workpiece placed at the mainboard module 3, so as to conveniently check and record the processing operation.

[0030] When the workpiece to be pressed is placed in place, the driving member 5 drives the pressing assembly to enter the mainboard module 3, and the pressing assembly is activated to realize the workpiece pressing operation.

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

[0032] In this embodiment, dampers are provided at both the receiving wheel 12 and the unwinding wheel 13, and the unwinding and rewinding of the film tape are precisely controlled by the dampers.

[0033] The pressing assembly includes a slider 6 and a pressing portion connected to the slider 6. The working platform 2 is provided with a transversely arranged guide rail 7. The slider 6 is connected to the guide rail 7. The driving member 5 is fixedly connected to the working platform 2 and the driving member 5 is connected to the slider 6.

[0034] Since the slider 6 is connected to the guide rail 1 7 , the entire pressing assembly can be stably translated relative to the mainboard module 3 under the action of the driving member 1 5 .

[0035] Ultimately, it is ensured that the pressing components can switch stably between the operating state and the non-operating state.

[0036] The work platform 2 is fixedly connected with a limit block 8 which is opposite to the slider 6 . The limit 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 mainboard module 3 .

[0037] The movement of the slider 6 is limited by the limit block 8 to ensure that the pressing assembly is stably located on the upper part of the mainboard module 3 during operation. Of course, the rigid contact of the slider 6 can be avoided under the action of the buffer 9, which effectively reduces noise and ensures stability.

[0038] The buffer 9 is an existing damping buffer, and therefore, the specific technical features of the buffer 9 will not be described in detail in the embodiment.

[0039] The laminating part includes a substrate 10, a film tape 11, a receiving wheel 12, a feeding wheel 13, a guide wheel assembly, a tension wheel assembly, a hot pressing part and a driving part 14. The substrate 10 is in a flat plate shape and is fixedly connected to the slider 6. The receiving wheel 12 and the feeding wheel 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 wheel assembly is connected to the substrate 10 and is located directly below the receiving wheel 12. The tension wheel assembly is connected to the substrate 10. The tensioning wheel assembly is located directly below the unloading wheel 13, one end of the film belt 11 is connected to the unloading wheel 13, and the other end of the film belt 11 is connected to the collecting wheel 12, and the middle part of the film belt 11 is wound around the guiding wheel assembly and the tensioning wheel assembly in sequence, and the film belt 11 between the guiding wheel assembly and the tensioning wheel assembly is a pressing section. In the initial state, the hot pressing part is located above the pressing section, and when the driving part 14 drives the hot pressing part to move downward, the hot pressing part can push the pressing section to the mainboard module 3.

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

[0041] Each time the hot pressing piece is pressed down, the film tape 11 is intermittently moved by a set distance, so as to ensure that a new film tape 11 is in contact with the workpiece to be pressed each time during hot pressing.

[0042] The excess glue overflowing from the workpiece to be pressed adheres to the film tape 11. To avoid the residual overflowed glue on the workpiece, in this embodiment, the film tape 11 is made of PI material (polyimide).

[0043] The film tape 11 with glue adhered to it finally enters the receiving wheel 12 , and the film tape 11 with glue adhered to it is collected by the receiving wheel 12 .

[0044] The guide wheel assembly includes roller one 15, roller two 16 and a correction assembly movably connected to the base plate 10, wherein roller one 15 is located in the middle of the base plate 10, roller two 16 is located in the lower part of the base plate 10, the correction assembly is located between roller one 15 and roller two 16, and the film belt 11 is sequentially wound around roller one 15 and roller two 16, and the film belt 11 between roller one 15 and roller two 16 is passed through the correction assembly.

[0045] Under the action of the correction component, the film belt 11 between the roller 15 and the roller 2 16 can be stably leveled to prevent the film belt 11 from bending when entering the receiving wheel 12.

[0046] The correction assembly includes a correction wheel 17, a correction wheel 18 and a rocker arm 19. The correction wheel 17 has protruding baffles 17a on both sides. The middle part of the rocker arm 19 is hinged on the base plate 10. The correction wheel 18 is connected to the outer end of the rocker arm 19. A pre-tightening member 21 is provided between the base plate 10 and the outer end of the rocker arm 19. Under the action of the pre-tightening member 21, the inner end of the rocker arm 19 has a downward swing and the correction wheel 18 has a tendency 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 film strip 11 is limited on the correction wheel 17 between the two baffles 17a. At the same time, the correction wheel 2 18 has a tendency to abut against the side of the correction wheel 17 between the two baffles 17a. Therefore, the film strip 11 passing through the correction wheel 17 and the correction wheel 2 18 will be stably flattened.

[0048] The preload member 21 is a hydraulic buffer.

[0049] The tensioning assembly includes roller three 22, roller four 23 and roller five 24 movably connected to the base plate 10, and the roller three 22, roller four 23 and roller five 24 are arranged from top to bottom, and the roller four 23 is located at the side between the line connecting roller three 22 and roller five 24, and the film belt 11 is wound around roller three 22, roller four 23 and roller five 24 in sequence.

[0050] Since the film strip 11 is wound around the roller 3 22, the roller 4 23 and the roller 5 24 in sequence, the film strip 11 can be properly tensioned under the action of the above-mentioned multiple rollers. Of course, since the film strip 11 has just been released from the unwinding wheel 13, the film strip here will not bend. The film strip 11 may bend only after being squeezed and deformed by the hot pressing part. Therefore, the above-mentioned guide wheel assembly is arranged adjacent to the receiving wheel 12.

[0051] It also includes a rocker arm 25, the inner end of which is hinged on the frame 1, and the roller 4 23 is movably connected to the outer end of the rocker arm 25. A torsion spring 26 is provided between the rocker arm 25 and the base plate 10. Under the elastic force of the torsion spring 26, the roller 4 23 at the outer end of the rocker arm 25 tends to be pressed tightly against the film strip 11.

[0052] The pendulum 25 has two functions: First, under the action of the torsion spring 26, the roller 23 can have a tendency to swing; Second, provide enough space for the roller 4 23 to connect.

[0053] The hot pressing part includes a pressing block 28, a heating rod 29 and a counterweight block 30. The substrate 10 is provided with a vertically arranged guide rail 21, the pressing block 28 is connected to the guide rail 21, the heating rod 29 is connected inside the pressing block 28, the driving member 2 14 is fixedly connected to the substrate 10 and the driving member 2 14 is connected to the pressing block 28, and the counterweight block 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 compact after being energized. In this embodiment, the temperature of the compact after the temperature is increased is 180 degrees Celsius.

[0055] The second driving member 14 is a cylinder. In the initial state, the piston rod of the cylinder pushes the pressing block 28 and makes the pressing block 28 have a tendency to move away from the main board module 3. Once the piston of the cylinder retracts, the pressing block 28 pushes the film tape 11 under its own gravity and makes it contact with the workpiece to be pressed.

[0056] It can be seen that the counterweight block 30 increases the weight of the pressing block, ensuring that the pressing block 28 has sufficient pressure to act on the workpiece to be pressed. Since the counterweight block 30 is detachably connected to the pressing block 28, the counterweight block 30 can be replaced or increased or decreased according to actual conditions to meet different pressing operation requirements.

[0057] The motherboard module is an existing positioning fixture. Corresponding motherboard modules are used for different products to be pressed. The problem that this patent application needs to solve is how to hot press the product. As for what kind of positioning fixture the product is connected to, that is, how the product is connected to the motherboard module, it is existing technology, and this part of the technical solution is not a technical problem that this patent application needs to solve. Therefore, the technical features of the motherboard module are no longer repeated in the embodiments.

[0058] This assembly press machine uses film tape and uses servo motors and rotary dampers to accurately control the rotation of the take-up wheel and the unwinding wheel, realizing the film tape winding function. The guide wheel assembly is responsible for guiding the film tape to prevent the film from being rolled up or deviating too much. The tension wheel assembly uses the elastic force of the torsion spring to ensure the tension of the entire film tape. This prevents the film tape from having no tension, causing the film tape to become loose during the next pressing, and the film tape cannot be accurately positioned under the pressure head. On the contrary, this solution can ensure that the film tape stably protects the pressing block during the pressing operation, and the glue is not easy to stick to the pressure head.

[0059] The overflowing glue will be stably carried away by the film tape.

[0060] At the same time, the pressing block uses a counterweight block to press, and the cylinder force is cancelled. The cylinder is only responsible for lifting the pressure head. When pressing small parts, the counterweight block relies on its own gravity to press small parts and products, so the pressing effect is more stable. The pressing force is not affected by external factors.

[0061] It can be seen that the entire pressing machine can avoid residual glue overflow on the workpiece during the pressing operation, effectively improving the quality of the finished product. And because there is no need to clean the relatively high temperature block, the operation is also safer The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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 only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
