Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubber diaphragm packaging, in particular to an automatic stacking device for rubber diaphragm packaging. BACKGROUND

[0002] As a key industrial component that relies on elastic deformation to achieve medium control, rubber diaphragm plays an irreplaceable role in many industrial scenarios such as flow control valves, pressure regulating valves, differential devices, etc. Its manufacturing process mainly covers core links such as raw material preparation and processing, mold design and positioning, and mold pressing vulcanization forming. The vulcanization forming process needs to rely on a press, and different specifications of rubber diaphragm can be produced by replacing the mold on the press. In the production process of rubber diaphragm, the transfer and stacking of the molded rubber diaphragm are important steps to ensure the efficient operation of the subsequent packaging link. Currently, the industry generally uses a transfer device to handle the molded rubber diaphragm. This type of device usually uses a suction nozzle to grab the rubber diaphragm and transfer it to a designated location for stacking to achieve centralized collection. However, the existing transfer device has obvious limitations in actual application and cannot meet the needs of diversified production and precise packaging. On the one hand, the grabbing mechanism of the existing device cannot flexibly adjust the direction of the suction nozzle. For rubber diaphragms with uneven surfaces, the suction nozzle cannot fully adhere to the surface of the diaphragm, making it difficult to stably grab and limiting its use. It is difficult to adapt to the discharging needs of rubber diaphragms of different shapes. On the other hand, in the packaging link of rubber diaphragm, the number of stacked rubber diaphragms needs to be counted manually, which is not only inefficient but also prone to errors due to human operation, resulting in inaccurate packaging quantities and making it difficult to achieve quantitative stacking and collection, causing many inconveniences to the subsequent packaging process.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-7 The present invention provides a technical solution: an automatic stacking device for rubber diaphragm packaging, comprising a support mechanism 1, wherein two first connecting rods 2 are installed at one end on the top of the front of the support mechanism 1 through a pin shaft, a rotating cylinder 3 for driving the first connecting rod 2 to rotate is installed on the rear side of the support mechanism 1, and a bracket 4 is installed on the other end of the first connecting rod 2 through a pin shaft. The support mechanism 1, the first connecting rod 2, and the bracket 4 form a four-bar mechanism. As the first connecting rod 2 rotates alternately clockwise or counterclockwise, the bracket 4 can move vertically to the right or left. A grabbing mechanism 5 is installed at the front end of the bracket 4. By adjusting the rotation stroke of the rotating cylinder 3, the rotation angle of the first connecting rod 2 can be changed, and then the height of the bracket 4 can be adjusted to change the grabbing height of the rubber diaphragm.

[0020] As a preferred solution, further, the supporting mechanism 1 includes a base 11 installed at the discharge port of the molding equipment, and limiting plates 12 are installed on the left and right sides of the top of the base 11. The outer wall of the limiting plate 12 is sleeved with a lifting plate 13 that can move up and down. The front of the lifting plate 13 is connected to the first connecting rod 2 through a pin shaft, and the rotating cylinder 3 is installed on the rear side of the lifting plate 13 to adjust the height of the lifting plate 13 to facilitate the grabbing of the rubber diaphragm. Positioning bolts 14 are screwed on the bottom of the left and right sides of the lifting plate 13, and the positioning bolts 14 are in contact with the limiting plate 12 to achieve the positioning of the lifting plate 13.

[0021] As a preferred solution, further, the grabbing mechanism 5 includes a mounting plate 51 installed at the front end of the bracket 4, and a first rotatable shaft 52 is installed at the center position of the mounting plate 51 through a bearing, and a first straight gear 53 is installed on the top of the first rotating shaft 52. A driver 54 is installed on the rear side of the lower surface of the mounting plate 51, and the first straight gear 53 is driven to rotate by the driver 54, thereby rotating the first rotating shaft 52, so that the adsorption component 55 is staggered with the air holes on the rubber diaphragm to prevent failure when grabbing the rubber diaphragm. An adsorption component 55 is installed at the bottom end of the first straight gear 53 for grabbing the workpiece, and a stacking height limiting component 56 is installed at the front end of the lower surface of the mounting plate 51 to determine the packaging quantity by limiting the grabbing height.

[0022] As a preferred embodiment, further, the adsorption assembly 55 includes a dust cover 551 installed at the bottom end of the first rotating shaft 52, a motor 552 is installed on the lower surface of the dust cover 551, a turntable 553 is installed on the output end of the motor 552, a ridge 554 is installed on the lower surface of the turntable 553, and at least three rotating units 555 are installed equidistantly along the circumference of the outer edge of the lower surface of the dust cover 551. The turntable 553 is driven by the motor 552 to rotate, so that the ridges 554 are spirally distributed on the lower surface of the turntable 553, and the rotating unit 555 can be moved inward or outward to change the grasping angle.

[0023] More specifically, when grabbing rubber diaphragms of different shapes, the motor 552 is started to drive the turntable 553 to rotate, and the spiral ridges 554 rotate with the turntable 553, squeezing and pushing the fan gear 5552 to rotate around the support column 5551, thereby driving the suction nozzle 5554 to deflect inward or outward, and adjusting it to an angle that completely fits the surface of the rubber diaphragm to ensure stable grabbing; through the above-mentioned structural linkage, the grabbing mechanism 5 can flexibly adapt to the grabbing needs of rubber diaphragms of different heights and shapes, and realize automatic quantitative packaging, which significantly improves operational efficiency and applicability.

[0024] As a preferred solution, further, the rotating unit 555 includes a support column 5551 installed on the outer edge of the lower surface of the dust cover 551, and a fan gear 5552 is installed on the inner side of the bottom of the support column 5551 through a pin shaft, and the fan gear 5552 is meshed with the ridge 554, so that the suction nozzle 5554 can be rotated during transmission, and a suction nozzle support 5553 is vertically installed at the bottom of the fan gear 5552, and a suction nozzle 5554 is installed at the bottom of the suction nozzle support 5553, and the suction nozzle 5554 is used to suck the workpiece.

[0025] As a preferred solution, further, the stacking height limiting component 56 includes a box body 561 installed at the front end of the lower surface of the mounting plate 51, and two left-right symmetrical scale plates 562 are installed on the front of the box body 561. The scale plates 562 are length units and are used to measure the stacking height of the workpieces. A second rotating shaft 563 is installed on the front of the box body 561 with the scale plates 562 as the center through a bearing, and one end of a second connecting rod 564 and a second spur gear 565 are installed at the front and rear ends of the second rotating shaft 563 respectively, and the two second spur gears 565 are meshed and connected to allow the two second connecting rods 564 to rotate in opposite directions. The two second connecting rods 564 are symmetrically arranged on the left and right. When the two second connecting rods 564 move in the direction, the photoelectric sensor 5611 can be horizontally raised and lowered, and a worm gear 566 is installed at the rear end of the second spur gear 565 on the right. The bottom of the right side wall of the box body 561 is installed with a The worm 567 meshing with the worm gear 566 allows the second spur gear 565 to rotate under the transmission condition of the worm 567 and the worm gear 566. An observation window 568 is provided in the middle of the front of the second connecting rod 564. The scale of the dial 562 displayed in the observation window 568 is used as a height measurement standard. The other end of the second connecting rod 564 is installed with one end of the third connecting rod 569 through a pin shaft. The other end of the third connecting rod 569 is installed with a connecting plate 5610 through a pin shaft. A photoelectric sensor 5611 electrically connected to the rotating cylinder 3 is installed at the center position of the connecting plate 5610. The laser of the photoelectric sensor 5611 can sense the stacking height of the rubber diaphragm to realize the quantitative collection of the rubber diaphragm. The laser emitted by the photoelectric sensor 5611 is perpendicular to the center line of the dust cover 551. When transporting the rubber diaphragm, ensure that the laser of the photoelectric sensor 5611 can be blocked by the rubber diaphragm with a certain stacking height.

[0026] More specifically, when the stacking height threshold of the rubber diaphragm needs to be adjusted, the operator rotates the worm 567 and utilizes the meshing transmission of the worm 567 and the worm wheel 566 to drive the second spur gear 565 on the right to rotate, and then drives the second spur gear 565 on the left to rotate in the opposite direction through the meshing of the two second spur gears 565, so that the two second connecting rods 564 swing upward or downward synchronously; when the second connecting rod 564 swings, the connecting plate 5610 and the photoelectric sensor 5611 are driven to rise and fall horizontally through the third connecting rod 569. At this time, the operator can adjust the stacking height threshold of the rubber diaphragm by rotating the worm 567 and utilizing the meshing transmission of the worm 567 and the worm wheel 566 to drive the second spur gear 565 on the right to rotate. The observation window 568 on the second connecting rod 564 reads the scale value of the dial 562 until the height of the photoelectric sensor 5611 reaches the preset stacking height threshold, and the adjustment is completed; in the stacking process of the rubber diaphragms, as the number of diaphragms increases, the stacking height gradually increases. When the height reaches the set threshold, the rubber diaphragm blocks the laser beam emitted by the photoelectric sensor 5611, and the photoelectric sensor 5611 triggers an electrical signal and transmits it to the rotating cylinder 3, controlling the rotating cylinder 3 to stop moving, thereby completing the quantitative stacking and realizing the precise quantitative packaging of the rubber diaphragms.

[0027] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0028] Step 1: Install the support mechanism 1 at the discharge end of the rubber diaphragm forming equipment, and drive the first connecting rod 2 to rotate clockwise and counterclockwise by rotating the cylinder 3, so that the bracket 4 can swing left and right to form a rubber diaphragm transfer track; Step 2: The rubber diaphragm is sucked by the suction force of the suction nozzle 5554. When the rubber diaphragm reaches the packaging position, the suction nozzle 5554 is cut off and the rubber diaphragm falls. In this reciprocating motion, the rubber diaphragm can be stacked and collected. Step 3: When it is necessary to grasp rubber diaphragms of different shapes, the driver 54 rotates the first spur gear 53, causing the dust cover 551 to rotate, thereby changing the position of the suction nozzle 5554 so that the suction nozzle 5554 is offset from the air holes on the surface of the rubber diaphragm to prevent the suction nozzle 5554 from losing its grasping function. The motor 552 drives the turntable 553 to rotate clockwise or counterclockwise. The inclined surface of the ridge 554 presses the sector gear 5552 inward or outward according to the tilt direction, thereby causing the sector gear 5552 to swing back and forth, changing the tilt angle of the suction nozzle 5554 on the suction nozzle holder 5553, so that the suction nozzle 5554 can fully contact the concave or convex surface of the rubber diaphragm, thereby achieving the grasping of different types of rubber diaphragms. Step 4. When the stacking height of the rubber diaphragms needs to be adjusted, under the premise that the rotation angle of the rotating cylinder 3 remains unchanged, the worm 567 is rotated clockwise or counterclockwise, and under the transmission condition of the worm 567 and the worm wheel 566, the second spur gear 565 and the two second spur gears 565 move relative to each other, and the two second connecting rods 564 swing up or down at the same time, and the angle between the second connecting rod 564 and the third connecting rod 569 becomes smaller or larger, so that the photoelectric sensor 5611 rises or falls, and the size of the dial 562 seen in the observation window 568 is the stacking height of the rubber diaphragms. As the stacking height of the rubber diaphragms increases, when the light of the photoelectric sensor 5611 is blocked by the rubber diaphragms, the photoelectric sensor 5611 is triggered, and the rotating cylinder 3 stops moving, so that the rubber diaphragms are packaged in equal quantities.
