Description

Technical Field

[0001] The invention belongs to the technical field of new energy automobile manufacturing, and in particular relates to a material taking device for die-casting production of automobile lampshades. Background Art

[0002] Car lampshades can gather and refract the light emitted by the bulb, making the light more concentrated and directional, thereby improving the lighting effect and ensuring that the driver has a good view at night or in bad weather conditions. They can also provide a layer of physical protection for the bulb to prevent it from being damaged by external factors such as collision, dust, water vapor, and flying stones.

[0003] The die-casting process can achieve rapid prototyping and produce a large number of lampshade products in a short period of time. Compared with other manufacturing processes, it greatly shortens the production cycle and meets the needs of large-scale production in the automotive industry. Therefore, it is widely promoted and applied. The temperature of the lampshade that has just been die-cast is high, and direct material removal may cause burns to the operator. Therefore, it is necessary to cooperate with the material removal equipment to complete the material removal of the lampshade. In the actual material removal process, the lampshade is ejected from the mold by the push device and the push plate, but the strength of the push force is fixed. When the lampshade and the mold are adhered due to uneven spraying or insufficient dosage of the release agent, excessive push force will cause deformation or damage to the lampshade, affecting the processing quality of the lampshade. At this time, the staff can only actively cooperate with the material removal work, which greatly increases the burden on the staff and causes low material removal efficiency.

[0043] A material moving mechanism 7 is fixedly installed on one side of the upper end of the base 1, and the material moving mechanism 7 is used to transfer the taken out lampshade. The material moving mechanism 7 includes a U-shaped fixing plate 71 fixedly installed on the upper end of the base 1, and an electric push rod 72 is rotatably sleeved in the U-shaped fixing plate 71. A motor rotating assembly 73 for driving the electric push rod 72 to rotate is fixedly installed on the upper end of the base 1, and a cross plate 74 is fixedly connected to the upper output end of the electric push rod 72. A hollow adsorption seat 75 is fixedly installed on the lower side of one end of the cross plate 74, and a plurality of negative pressure suction holes 76 are opened at the lower end of the hollow adsorption seat 75. A vacuum pump 77 is fixedly installed on the lower end of the cross plate 74, and the air inlet of the vacuum pump 77 is fixedly connected to the hollow adsorption seat 75.

[0044] A PLC controller is also fixedly installed on the upper end of the base 1, and the PLC controller is electrically connected to the pressurizing and pushing mechanism 2, the pushing force monitoring and feedback mechanism 3, the vibration de-adhesion mechanism 4, the pressure adjustment mechanism 5, the material taking trigger mechanism 6 and the material moving mechanism 7 respectively.

[0045] The operating principle of the present invention is described as follows: when the die-casting production of the lampshade is completed and the material needs to be taken, the PLC controller controls the hydraulic pump 24 to work, and the hydraulic pump 24 cooperates with the pressurized pipe 23 to transport the pressure oil in the oil storage tank 22 to multiple hydraulic cylinders 21, and the lampshade is quickly pushed out from the lower mold 9 by the thrust force generated by the moving end of the hydraulic cylinder 21 in cooperation with the push rod 11 and the push plate 12, so as to realize automatic material taking. When adhesion occurs between the lampshade and the lower mold 9, the hydraulic cylinder 21 is affected by the adhesion force between the lampshade and the lower mold 9 during the process of pushing the push plate 12 upward, so that the vibration de-adhesion mechanism 4 cooperates with the force-bearing rod 11 to push the push plate 12 upward. 33 overcomes the action of the push spring 34 and moves relative to the feedback shell 31, and synchronously drives the pressing rod 311 to move toward the adhesion feedback switch 39, until the pressing rod 311 acts on the adhesion feedback switch 39, indicating that there is indeed adhesion between the lampshade and the lower mold 9. At this time, the PLC controller controls the hydraulic pump 24 to stop working, so that the hydraulic cylinder 21 cooperates with the push spring 34 to generate a push force on the lampshade in the current state for 20 seconds, so that the lampshade undergoes stress relaxation after being subjected to a continuous small force for a period of time, so that the stress of adhesion is reduced, and the total force required for separation is reduced, which is convenient for the subsequent continued material removal work;

[0046] After the top thrust is maintained for 20 seconds, if the adhesion problem between the lampshade and the lower mold 9 is not completely solved at this time, that is, the current top thrust still cannot make the vibration de-adhesion mechanism 4 move up in the direction opposite to the feedback shell 31, so that the pressing rod 311 still acts on the adhesion feedback switch 39, at this time, the PLC controller first controls the power supply equipment to supply power to the positioning electromagnetic plate 35, and the positioning electromagnetic plate 35 generates a magnetism opposite to the positioning permanent magnetic strip 36, so that the positioning electromagnetic plate 35 and the positioning permanent magnetic strip 36 are fixed, thereby realizing the relative fixation of the vibration de-adhesion mechanism 4, and the PLC controller then controls the power supply equipment to supply power to the positive and negative electromagnetic plates 4 7 supplies alternating current, so that the positive and negative electromagnetic plates 47 generate the same or opposite magnetic force as the positive and negative permanent magnetic plates 46, and then drive the reciprocating plate 43 to cooperate with the reciprocating rod 42 to drive the connecting plate 44 to make the push rod 11 and the push plate 12 move up and down, thereby generating a vibration force on the lampshade. The vibration causes a slight displacement and loosening of the tiny adhesion points, which can weaken the overall adhesion strength when accumulated. The adhesion force can be actively destroyed by slight vibration, thereby solving the adhesion problem of most lampshades when taking materials, without the need for direct human intervention in the operation, thereby greatly improving the convenience and efficiency of taking materials, and suitable for popularization and use;

[0047] After the vibration de-adhesion mechanism 4 works for 30 seconds, the PLC controller controls the power supply device to stop supplying power to the positive and negative electromagnetic plates 47, so that the vibration de-adhesion mechanism 4 stops working, and synchronously controls the hydraulic pump 24 to continue working, and cooperates with the hydraulic cylinder 21 to provide further thrust, and the PLC controller synchronously controls the adjustment motor 53 to move, and the adjustment motor 53 drives the adjustment screw 52 to move, and the adjustment seat 54 drives the conductive contact 55 to slide synchronously on the resistor rod 56 through the threaded sleeve effect of the adjustment screw 52 and the adjustment seat 54, so that the access resistance of the resistor rod 56 gradually decreases, and the conductive contact 55 and the resistor rod 56 are connected. 6 is connected in series to the power supply circuit of the hydraulic pump 24, which is a DC pump, so that the power of the hydraulic pump 24 is gradually increased, thereby providing a greater thrust force to take the material. The gradual increase in force can more accurately control the separation process of the lampshade and the lower mold 9, avoiding irreparable losses caused by excessive force at once, and product adhesion means that there is a strong adhesion between the product and the mold. Conventional thrust force cannot overcome this adhesion to smoothly take out the product. By increasing the thrust force, a greater separation force can be provided, which helps to break the adhesion between the product and the mold, thereby achieving effective separation of the product;

[0048] In the process of increasing the push force to further remove the material, if the adhesion force between the lampshade and the lower mold 9 is still very large at this time, the vibration anti-adhesion mechanism 4 further overcomes the action of the push spring 34 and moves relative to the feedback shell 31, so that the pressing rod 311 drives the adhesion feedback switch 39 and the mounting plate 38 to move further downward along the guide slide bar 37 to overcome the elastic force of the compensation spring 310, until the mounting plate 38 acts on the warning switch 312, indicating that the adhesion force between the lampshade and the lower mold 9 cannot be overcome to complete the material removal work. At this time, the PLC controller sends a signal to the receiving terminal of the staff to remind the staff to make corresponding processing;

[0049] During the downward movement of the upper mold 10 relative to the lower mold 9, the trigger plate 614 on the outer wall of the upper mold 10 first contacts the upper side of the extension plate 610 during the downward movement, thereby driving the extension plate 610 to turn downward through the rotation connection between the rotating shaft 69 and the side plate 68 to overcome the action of the torsion spring 611, until the trigger plate 614 passes through the extension plate 610 and moves to the lower side of the extension plate 610. At this time, the extension plate 610 is reset again under the action of the torsion spring 611. When the die-casting production is completed and the upper mold 10 needs to be separated from the lower mold 9, during the upward movement and reset of the upper mold 10, the trigger plate 614 will act on the trigger switch 613 on the lower side of the extension plate 610. At this time, because the baffle 612 is blocked on the upper side of the extension plate 610, the extension plate 610 will not further flip upward. After the trigger switch 613 is pressed and triggered, it means that the die casting is completed and the material picking work can be carried out. At this time, the PLC controller controls the hydraulic pump 24 to work to pick up the material. When the die casting work is detected to be completed, the material picking work can be automatically triggered to proceed, thereby making the material picking action more compatible with the rhythm of the die casting production, making the entire die casting production process more coherent, and improving production efficiency;

[0050] When the upper die 10 is completely separated from the lower die 9, the extension plate 610 drives the vertical plate 67 and the sliding plate 64 to move up to the highest point. At this time, the sliding plate 64 presses the start switch 66. At this time, the PLC controller controls the material moving mechanism 7 to start the action, and the PLC controller controls the electric slide rail 61 to drive the trigger shell 62 to move backward, so that the extension plate 610 is relatively separated from the trigger plate 614. Under the action of the pull-down spring 65, the sliding plate 64 drives the extension plate 610 to move down and reset, waiting for the next die-casting work;

[0051] The PLC controller controls the motor rotating assembly 73 to drive the electric push rod 72 to rotate, so that the cross plate 74 and the hollow adsorption seat 75 move between the lower mold 9 and the upper mold 10, and the electric push rod 72 then drives the hollow adsorption seat 75 to move downward, so that the hollow adsorption seat 75 contacts the upper surface of the lampshade pushed out, and the PLC controller controls the vacuum pump 77 to work, and the vacuum pump 77 forms a negative pressure suction force in the hollow adsorption seat 75, and cooperates with the negative pressure suction hole 76 to achieve a stable connection between the hollow adsorption seat 75 and the lampshade, and then the lampshade is transferred to the side through the motor rotating assembly 73, and the taken out lampshade can be automatically transferred when the material is taken out, thereby further improving the continuity of the die-casting production of the lampshade, and when the hollow adsorption seat 75 needs to release the connection with the lampshade, the PLC controller controls the vacuum pump 77 to stop working and stop providing negative pressure suction force on the hollow adsorption seat 75.
