Description

Technical Field

[0001] This invention belongs to the field of vacuum vibratory press technology, and specifically relates to a vacuum vibratory press. Background Technology

[0002] A vacuum vibratory press is a device used for pressing various materials. It combines the functions of vacuum and vibration. By creating a vacuum environment, the material to be pressed is placed between upper and lower hot-press molds. Then, the action of vibration and pressure causes the materials to bond tightly together. The vacuum environment helps to eliminate air between the materials, reducing air bubbles and voids, thereby improving the pressing quality. Vacuum vibratory presses are widely used in electronics, automotive, aerospace, and new energy fields. They can be used to press various materials, such as metals, plastics, rubber, and glass. For example, in the electronics industry, vacuum vibratory presses can be used to press electronic components and package integrated circuits.

[0003] The authorized publication number "CN109263071A" describes "a vacuum vibratory press for quartz stone preparation, including a base, with side support rods fixed to the upper surfaces of both the left and right ends of the base, a PLC controller installed on the side of one side support rod, a top plate fixed to the upper end of the side support rod, a horizontal slide rail on the left side of the upper surface of the base, a slider slidably connected to the slide rail inside the slide rail, and a first horizontal electric telescopic rod installed on the left end of the slide rail. This vacuum vibratory press for quartz stone preparation uses a mixing tank to stir raw materials such as quartz sand, ceramic fragments, glass fragments, and resin binders to ensure the uniformity of material mixing. A belt moves the mold seat and mold blank, and the mold seat and vacuum hood are used to isolate the mold blank. The vacuum pump creates a vacuum, which, combined with stirring, effectively separates air from the mold blank, ensuring process quality. The overall operation is smooth and the work efficiency is high."

[0004] The aforementioned patent uses a mixing tank to mix raw materials such as quartz sand, ceramic fragments, glass fragments, and resin binders, ensuring the uniformity of material mixing. A belt moves the mold base and mold blank, and the mold base and vacuum hood are used to isolate the mold blank. The vacuum pump creates a vacuum, which, combined with mixing, effectively separates air from the mold blank, ensuring process quality. The overall operation is smooth and the work efficiency is high. However, during the operation of the vacuum vibratory press, the molding material is very prone to sticking to the bottom of the vibratory block during the vibratory pressing process, causing the bottom of the vibratory block to become uneven. This results in the top of the molding material being uneven in subsequent continuous vibratory pressing. To address this, we propose a vacuum vibratory press. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this solution, during the fabrication process of the diaphragm, the two lead screws in the two sets of pushing components rotate in the forward direction, causing the two lead screws to slide and move the two sliding frames through sliding engagement with them. During the movement of the two sliding frames, the two sliders slide and engage with the two guide rails to ensure the parallel movement of the two sliding frames. The two sliding frames push the two electric clamps to move horizontally. Two positioning lasers detect that the two diaphragms are close to one end of the diaphragm and activate the two electric clamps to clamp one end of the diaphragm. The two sets of driving components drive the two lead screws to rotate in the opposite direction. The two lead screws slide and engage with the two sliding frames to push the two sliding frames back to their original positions. The two sliding frames then drive the two electric clamps back to their original positions. The two electric clamps simultaneously pull the diaphragm, causing it to unfold inside the vacuum chamber. By pulling the diaphragm, it is positioned between the pressure plate and the molding material, effectively preventing the molding material from sticking to the bottom of the pressure plate, ensuring the smoothness of the bottom of the pressure plate, and avoiding unevenness on the top of the molding material later.

[0017] 2. In this solution, when the two positioning lasers sense that the two sliding frames have returned to zero and reset, the two sets of drive components drive the two lead screws to rotate in the forward direction again. The two lead screws push the two sliding frames to shift in the forward direction by 2-3cm through sliding cooperation with the two sliding frames, thereby avoiding the diaphragm from being stretched and broken.

[0018] 3. In this solution, during the fabrication process, when the two positioning lasers detect a positive offset of 2-3cm between the two sliding frames, the two third electric telescopic rods are powered on and activated. The two third electric telescopic rods push the gate downwards, bringing the gate closer to the base plate. The gate and the base plate work together to cut the diaphragm. One end of the cut diaphragm falls to the top of the molding material, while the two electric clamps release their grip on the other end of the diaphragm, allowing the diaphragm to be evenly laid on the top of the molding material.

[0019] 4. In this solution, the feed inlet connects the sealing cover and the vacuum cover, and allows the diaphragm to pass through. The sealing cover is detachably installed on the top of the vacuum cover and accommodates the material rack and the winding end of the diaphragm. The first roller, the second roller, and the auxiliary roller are used to deflect the diaphragm. Among the first roller, the second roller and the auxiliary roller, the first roller and the second roller are close together to clamp the diaphragm, and the auxiliary roller is offset from the second roller. The auxiliary roller deflects the unfolded end of the diaphragm between the guillotine and the base plate. The material rack supports the diaphragm in the winding state through the rotating shaft. The ratchet assembly is used to limit the unidirectional rotation of the diaphragm in the winding state. The unfolded end of the diaphragm is pulled by two electric clamps. The diaphragm deflects around the first roller, the second roller, and the auxiliary roller, accurately guiding the diaphragm between the guillotine and the base plate, which facilitates the cutting of the diaphragm.

Diaphragm 22, diaphragm 22 is fixedly connected to the inner wall of vacuum chamber 3 via a transmission mechanism; and The fabric feeding mechanism is located between the inner walls of the vacuum chamber 3 and is connected to the diaphragm 22 to feed the fabric onto the diaphragm 22.

[0024] In this invention, the bracket 1 is used to support and fix the vacuum platform 2. The vacuum platform 2 is used to accommodate and fix the vacuum hood 3, the lifting mechanism, the vibration pressing mechanism, and the conveyor belt 14. At the same time, the vacuum platform 2 supports and fixes the PLC control box 39 and the air compressor 40. The lifting mechanism is used to lift and move the vacuum hood 3, the transmission mechanism, the cloth feeding mechanism, and the vibration pressing mechanism. The vibration pressing mechanism is used to apply pressure to the pressure plate 10. The transmission component is used to transport the diaphragm 22. The cloth feeding mechanism is connected to the diaphragm 22 and is used to pull the diaphragm 22.

[0025] The fabric-making mechanism includes a drive assembly, a push assembly, and a shearing assembly. There are two sets of push assemblies, which are located between the inner walls of the vacuum chamber 3 and are connected to the diaphragm 22. There are also two sets of drive assemblies, which are located at the side of the vacuum chamber 3 and are connected to the two sets of push assemblies. The shearing assembly is located between the inner walls of the vacuum chamber 3 and is situated between the transmission mechanism and the two sets of push assemblies.

[0026] In this invention, two sets of pushing components are used to pull the diaphragm 22 to move, two sets of driving components are used to provide power to the two sets of pushing components, and a shearing component is used to cut the diaphragm 22.

[0027] The system includes an auxiliary support block 26, a sliding frame 28, a guide rail 29, a slider 30, a positioning laser 31, an electric clamp 32, and a lead screw 33. The auxiliary support block 26 is fixedly connected to the inner wall of the vacuum chamber 3. The lead screw 33 is disposed between the inner walls of the vacuum chamber 3, with one end of the lead screw 33 rotatably connected to the inner wall of the vacuum chamber 3 and the other end of the lead screw 33 rotatably connected to the auxiliary support block 26. The guide rail 29 is fixedly connected to the inner wall of the vacuum chamber 3, and the guide rail 29 is parallel and corresponding to the lead screw 33. The sliding frame 28 is sleeved on the circumferential surface of the guide rail 29. The electric clamp 32 is fixedly connected between the inner walls of the sliding frame 28. The positioning laser 31 is fixedly connected to the side end of the sliding frame 28. The slider 30 slides between the inner walls of the guide rail 29 and is connected to the sliding frame 28.

[0028] In this invention, the auxiliary support block 26 is used to assist in supporting the lead screw 33. The lead screw 33 pushes the sliding frame 28 to move through sliding engagement with the sliding frame 28. The guide rail 29 is used to accommodate the sliding of the slider 30. The electric clamp 32 is used to clamp and fix the diaphragm 22. The positioning laser 31 uses laser emission to position the sliding frame 28 in real time. The slider 30 guides the movement of the sliding frame 28 through sliding engagement with the guide rail 29, ensuring the parallel movement of the guide rail 29. During the fabrication process of the diaphragm 22, the two lead screws 33 in the two sets of pushing components rotate in the forward direction, so that the two lead screws 33 push the two sliding frames 28 to move through sliding engagement with the two sliding frames 28. During the movement of the two sliding frames 28, the two sliders 30 ensure the parallel movement of the two sliding frames 28 through sliding engagement with the two guide rails 29. The two sliding frames 28 push the two electric clamps 32 to translate. The two positioning lasers 31 detect the two diaphragms 22 approaching each other. Near one end of the diaphragm 22, two electric clamps 32 are activated to hold one end of the diaphragm 22. Two sets of drive components drive two lead screws 33 to rotate in opposite directions. The two lead screws 33 push the two sliding frames 28 to reset through sliding cooperation with the two sliding frames 28. The two sliding frames 28 drive the two electric clamps 32 to reset. The two electric clamps 32 simultaneously pull the diaphragm 22 to move, so that the diaphragm 22 unfolds inside the vacuum chamber 3. When the two positioning lasers 31 sense that the two sliding frames 28 have returned to zero and reset, the two sets of drive components drive the two lead screws 33 to rotate in the forward direction again. The two lead screws 33 push the two sliding frames 28 to shift forward by 2-3 cm through sliding cooperation with the two sliding frames 28, thereby preventing the diaphragm 22 from being taut and breaking. By pulling the diaphragm 22, the diaphragm 22 is positioned between the pressure plate 10 and the molding material, effectively preventing the molding material from sticking to the bottom of the pressure plate 10, ensuring the smoothness of the bottom of the pressure plate 10, and avoiding unevenness on the top of the molding material in the future.

The output end of the servo motor 37 extends to the inner walls of the gear cover 34 and is fixedly connected to the driving gear 36.

[0030] In this invention, the gear cover 34 is used to seal and protect the driven gear 35 and the driving gear 36. The driven gear 35 drives the lead screw 33 to rotate. The driving gear 36 drives the driven gear 35 to rotate through meshing with the driven gear 35. The servo motor 37 drives the driving gear 36 to rotate. When the single drive assembly drives the lead screw 33 to rotate, it powers on the servo motor 37. The output end of the servo motor 37 drives the driving gear 36 to rotate. The driving gear 36 drives the driven gear 35 to rotate through meshing with the driven gear 35. The driven gear 35 drives the lead screw 33 to rotate, thereby providing torque for the rotation of the lead screw 33, and thus providing power for the parallel movement of the electric clamp 32.

[0043] A method of using a vacuum vibratory press includes the following steps: S1, Fabric: After the molding material is placed on top of the conveyor belt 14, the conveyor belt 14 transports the molding material to the bottom of the pressure plate 10. Power is applied to activate the two first electric telescopic rods 5. The output ends of the two first electric telescopic rods 5 push the vacuum cover 3 downwards, causing the vacuum cover 3 to press down to the top of the conveyor belt 14. Simultaneously, the vacuum cover 3, together with the vacuum platform 2, forms a sealed cavity for the molding material. The two lead screws 33 in the two sets of pushing components rotate forward, causing the two lead screws 33 to push the two sliding frames 28 to move through sliding engagement with the two sliding frames 28. During the movement of the two sliding frames 28, the two sliders 30 ensure the parallel movement of the two sliding frames 28 through sliding engagement with the two guide rails 29. The two sliding frames 28 push the two electric clamps 32 to move horizontally. The two positioning lasers 31 detect that the two diaphragms 22 are close to one end of the diaphragm 22, and power is applied to activate the two electric clamps 32 to clamp one end of the diaphragm 22. The two sets of drive components drive the two lead screws 33 to rotate in opposite directions. The two lead screws 33 push the two sliding frames 28 to reset through sliding cooperation with the two sliding frames 28. The two sliding frames 28 drive the two electric clamps 32 to reset. The two electric clamps 32 simultaneously pull the diaphragm 22 to move, so that the diaphragm 22 unfolds in the vacuum chamber 3. When the two positioning lasers 31 sense that the two sliding frames 28 have returned to zero and reset, the two sets of drive components drive the two lead screws 33 to rotate in the forward direction again. The two lead screws 33 push the two sliding frames 28 to shift forward by 2-3 cm through sliding cooperation with the two sliding frames 28, thereby avoiding the diaphragm 22 from being taut and breaking. By pulling the diaphragm 22, the diaphragm 22 is positioned between the pressure plate 10 and the molding material, which effectively prevents the molding material from sticking to the bottom of the pressure plate 10, ensuring the smoothness of the bottom of the pressure plate 10, avoiding the unevenness of the top of the molding material, and realizing the fabrication of the diaphragm 22. S4. Cutting and laying out the fabric: During the fabrication process, the unfolded end of the diaphragm 22 is pulled by two electric clamps 32. The diaphragm 22 deflects around the first roller shaft 19, the second roller shaft 20 and the auxiliary roller shaft 21, precisely guiding the diaphragm 22 between the guillotine 23 and the base plate 24, facilitating the cutting of the diaphragm 22. When the two positioning lasers 31 detect that the two sliding frames 28 have shifted forward by 2-3 cm, the two third electric telescopic rods 25 are activated. The two third electric telescopic rods 25 push the guillotine 23 downward, bringing the guillotine 23 closer to the base plate 24. The guillotine 23 and the base plate 24 cooperate to cut the diaphragm 22. One end of the cut diaphragm 22 falls to the top of the forming material, while the two electric clamps 32 release the clamps on the other end of the diaphragm 22, allowing the diaphragm 22 to be evenly laid on the top of the forming material, thus achieving the cutting and laying of the diaphragm 22. S2, Vibratory compression molding: When the power is turned on again, the second electric telescopic rod 11 is started. The output end of the second electric telescopic rod 11 pushes the pressure plate 10 down. The pressure plate 10 extrudes and shapes the molding material. At the same time, multiple vibrators 16 are started. The multiple vibrators 16 vibrate the molding material and remove the air inside the molding material to achieve vibration and compression molding of the molding material. S3, Vacuuming: After vibration compression molding, the air compressor 40 is started. The air compressor 40 extracts air from the sealed cavity through the pipeline, further reducing the air in the molding material and achieving vacuuming of the molding material.
