Description

Technical Field

[0001] The present invention relates to the technical field of superhard material diamond synthesis, and particularly to an integrated production system and production method for cup-shaped powder products. Background Art

[0002] Powder products are made by pressing and sintering powders through a hydraulic press. Among them, cup-shaped powder products are one of the most important types of powder products. At present, the pressing method for cup-shaped powder products includes processes such as pressing into shape, manual turning, loading into trays, and loading onto vehicles. Among them, before turning, the product is pushed to the front end of the mold cavity through a feeding box, the operator scrapes the product to the front end of the feeding pallet with a hook, manually picks up the product and turns it over, and then stacks it on a special tray. When a box is full, it is manually loaded onto a special vehicle. This method has the following defects: 1. When the employee scrapes the product to the front end of the feeding pallet with a hook, there is a risk of pinching hands; 2. Manual scraping of products, turning over, tray loading, and vehicle loading result in extremely high labor intensity; 3. The products pressed by the hydraulic press are in a state with the cup bottom facing up, and automatic palletizing cannot be achieved; 4. One person can only operate one device, which requires a large amount of manpower.

[0003] The Chinese patent invention specification with the publication number CN108994679A discloses an integrated production process and production system for ring-shaped thin-walled powder products. This method can realize the automation of the entire process of pressing, milling, transporting, and palletizing ring-shaped thin-walled powder products. However, since the powder products after pressing are relatively fragile, they are easily broken when grabbed by the grabbing manipulator of the automatic palletizer; in addition, cup-shaped powder products do not require milling, and after palletizing, they still need to be sent to a drying kiln for drying. This method is not applicable to cup-shaped powder products. Summary of the Invention

[0012] The present invention also discloses an integrated production method for cup-shaped powder products, including the following steps:

[0013] (1) Using a hydraulic press to press the product into a cup shape;

[0014] (2) Feed the pressed product into the tipping bucket for turning it over and then send the pressed product to the product transfer mechanism;

[0015] (3) Feed the turned-over product into the automatic palletizing mechanism through the product transfer mechanism for automatic palletizing;

[0016] (4) Load the palletized product into a special vehicle;

[0017] (5) Feed the palletized product into a drying kiln for drying.

[0018] Further, step (2) specifically includes the following processes:

[0019] (2.1) After the hydraulic press presses the product into shape, the slider of the hydraulic press rises back to the upper limit position, and the ejector device pushes the pressed product out of the mold cavity;

[0020] (2.2) The feeding mechanism pushes the product to the specified position on the right side of the mold cavity and at the same time feeds the material into the mold cavity;

[0021] (2.3) The feeding mechanism returns to its original position, and the slider of the hydraulic press starts to move downward to press the next batch of products. When the slider reaches the lower limit position, the next batch of products is pressed into shape, and at the same time, the pushing mechanism pushes the pressed product into the tipping bin;

[0022] (2.4) The rotating cylinder drives the tipping bin to rotate clockwise by an appropriate angle, so that the pressed product slides along the tipping bin onto the product transfer mechanism;

[0023] (2.5) The rotating cylinder drives the tipping bin to rotate counterclockwise back to its original position.

[0026] (3.1) The products enter the track of the automatic palletizing machine in sequence, and the automatic palletizing machine counts the number of products entering the track;

[0027] (3.2) When the track is full of products, the negative pressure suction cup moves above the track. At this time, multiple groups of suction cups arranged side by side on the negative pressure suction cup are respectively in one-to-one position correspondence with the products, and each group of suction cups is located directly above the center of the product;

[0028] (3.3) The negative pressure suction cups descend, and each group of suction cups cooperate with the negative pressure generator to transfer the clamped products to a special product tray for palletizing.

[0029] Step (4) specifically includes the following processes:

[0030] (4.1) Push the special vehicle to the designated position.

[0031] (4.2) Use the gripper manipulator to grab the special product tray onto the pallet rack of the automatic loading machine.

[0032] (4.3) Use the servo motor and lead screw to drive the pallet rack to move up and down and back and forth, so that the special product tray moves to a position corresponding to the carriage of the special vehicle.

[0033] (4.4) Use the servo motor and lead screw to push the special product tray into the carriage of the special vehicle.

[0034] The beneficial effects of the present invention are as follows:

[0035] The integrated production process of the cup-shaped powder products disclosed in the present invention integrates processes such as pressing and forming, automatic turning over, automatic palletizing, and automatic loading into an integrated continuous production process, realizing the integrated production of products. It not only reduces the labor intensity of employees, solves the problems of low automation degree in the production of cup-shaped powder products and easy fragmentation of products, but also improves safety.

[0036] By setting an automatic turning-over mechanism to turn over the product, the cup-shaped powder product becomes cup-mouth-up, facilitating the vacuum suction cups of the automatic palletizing mechanism to suck the product.

[0037] By setting leakage holes on the product transfer mechanism to remove defective products that are broken, the defective rate is reduced.

[0038] By using negative pressure suction cups to grab the products for automatic palletizing, the situation of fragmentation of cup-shaped powder products is avoided.

[0039] By setting limit tracks and electromagnets, the body of the special vehicle will not shake in the front-back and left-right directions when loading. Description of the Drawings

[0048] The working process of the integrated production system for cup-shaped powder products is as follows: First, a hydraulic press is used to press the product into a cup shape. Then, the pressed product is sent into the tipping bin for turning over and the pressed product is sent onto the product transfer mechanism; Next, the turned-over product is sent into the automatic palletizing mechanism through the product transfer mechanism for automatic palletizing; The palletized product is loaded into a special vehicle; Finally, the palletized product is sent into a drying kiln for drying.

[0049] Using a hydraulic press to press the product into a cup shape is an existing technology, so the pressing method will not be described in detail.

[0050] Sending the pressed product into the tipping bin for turning over and sending the pressed product onto the product transfer mechanism specifically includes the following processes:

[0051] (2.1) After the hydraulic press presses the product into shape, the slider of the hydraulic press rises back to the upper limit position, and the ejection device pushes the pressed product up from the mold cavity;

[0052] (2.2) The feeding mechanism pushes the product to the specified position on the right side of the mold cavity and at the same time feeds the material into the mold cavity;

[0053] (2.3) The feeding mechanism returns to its original position, and the slider of the hydraulic press starts to move downward to press the next batch of products. When the slider reaches the lower limit, the next batch of products is pressed into shape. At the same time, the push plate cylinder acts, and the piston rod of the push plate cylinder drives the first push plate 3 to push the pressed product into the tipping bin;

[0054] (2.4)The rotary cylinder 6 drives the tipping bin to rotate clockwise by an appropriate angle, such as 220 degrees, so that the pressed product slides down the tipping bin onto the first conveyor belt;

[0055] (2.5)The rotary cylinder 6 drives the tipping bin to rotate counterclockwise back to the initial position.

[0056] The pressed products first move forward successively under the drive of the first conveyor belt 5; when passing through the chute 9, the defective products that are broken will fall out through the leakage holes. After reaching the front end of the chute, they enter the palletizing track of the automatic palletizing mechanism along the second conveyor belt 10.

[0057] The automatic palletizing mechanism automatically palletizes the products, which specifically includes the following process:

[0058] (3.1)The products enter the automatic palletizing machine track successively, and the automatic palletizing machine counts the number of products entering the track;

[0059] (3.2)When the track is filled with products, the negative pressure suction cups move above the track. At this time, multiple groups of suction cups arranged side by side on the negative pressure suction cups correspond to the products one by one in position, and each group of suction cups is located above the center of the product;

[0060] (3.3)The negative pressure suction cups descend to the position of the cup mouth of the cup-shaped powder product. The programmable logic controller opens the solenoid valve, the valve group is opened, and the vacuum generator starts to work, generating negative pressure in the suction cups to suck the products, and then transporting the adsorbed products to the special product tray for palletizing.

[0061] The automatic loading mechanism automatically loads the palletized products, which specifically includes the following process:

[0062] (4.1)Push the special vehicle 50 to the designated position, connect the power supply of the electromagnet 45, generate a suction force on the special product vehicle to prevent the special product vehicle from moving left and right.

[0063] (4.2)Use the gripper manipulator to grab the special product tray to the pallet rack 41 of the automatic loading mechanism; this process is as follows: First, the gripper trolley 49 drives the robotic arm 39 to move back and forth, so that the gripper crossbeam 34 moves to directly above the special product tray, and then the lifting cylinder 32 acts. Driven by the piston rod, the gripper crossbeam 34 moves downward to the position of the special product tray; then the clamping cylinder acts. Driven by the piston rod of the clamping cylinder, the grippers 36 at both ends grab the special tray; then the piston rod of the lifting cylinder 32 moves upward to the initial position, and the gripper trolley 49 drives the robotic arm 39 to move forward to directly above the pallet rack 41, and through the actions of the lifting cylinder and the clamping cylinder, the special product tray is placed on the pallet rack 41.

[0064] (4.3) Drive the first lead screw nut 37 to move up and down by using the first lead screw 13 and the first motor 28, so that the tray rack moves to the height of the specified carriage. At the same time, drive the third lead screw nut 31 to move back and forth by using the third lead screw 15 and the third motor 29, so that the tray rack moves to the position corresponding to the specified carriage.

[0065] (4.4) The second lead screw 27 and the second motor 30 act to drive the second lead screw nut 38 to move left and right, thereby driving the second push plate 42 to move left and right, and pushing the special tray into the carriage of the special vehicle.

[0066] The integrated production method of the cup-shaped powder product has been described in the working process of the integrated production system of the cup-shaped powder product, so it will not be elaborated here.

When facing the front, the direction on the left hand side is defined as the left; it should be understood that the orientation or positional relationship indicated by the terms "front", "rear", "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the protected content of the present invention.
