Description

Technical Field

[0001] This invention relates to the field of injection molding technology, and in particular to a screw embedding device and method for an air spring chamber. Background Technology

[0002] An air spring is made by filling a sealed container with compressed air, utilizing the compressibility of gas to achieve its elastic effect. Air springs have ideal non-linear elastic characteristics. With the addition of a height adjustment device, the vehicle height does not change with the increase or decrease of load. The spring stiffness can be designed to be lower, resulting in good ride comfort.

[0003] like Figure 1 As shown, this product is the air chamber of a plastic air spring. Because air springs are subjected to large forces, a hollow metal screw needs to be embedded in the mounting hole of the air chamber to improve the load-bearing capacity of the plastic air chamber and meet the needs of use with large impacts and vibrations.

[0004] However, in the existing technology, there is no special equipment for embedding the air spring chamber, and it can only be completed manually step by step, resulting in low overall work efficiency and a high defect rate. Summary of the Invention

The execution end of the industrial robot A can drive the second manipulator to move to the discharge end of the second transfer mechanism to grab the air spring chamber and place the air spring chamber on the mold of the injection molding machine, and then grab the air spring chamber and place it on the second transfer mechanism. A chain plate conveyor is provided between the feeding mechanism and the preheating mechanism, and a collection box is placed at the end of the chain plate conveyor.

[0011] A further aspect of the present invention is that the third transfer mechanism includes a linear motor module d, and a positioning pin D for placing an air spring chamber is connected to the slide of the linear motor module d. The linear motor module d is perpendicular to the second transfer mechanism. The detection mechanism includes a support, and an industrial camera is connected to the support. The industrial camera is located above the linear motor module d.

[0015] A method for embedding an air spring chamber screw, using the aforementioned air spring chamber screw embedding device, includes the following steps: S1. Loading: The operator manually or the robot automatically places the air spring chamber to be embedded in the screw onto the positioning pin A on the chain conveyor A. The chain conveyor A drives the air spring chamber to move to the other end.

[0016] S2. Preheating: Driven by linear motor module a and linear motor module b, the first robotic arm grabs multiple air spring chambers, moves them, and places them on the positioning pin B of the chain conveyor B. The chain conveyor B drives the air spring chambers into the heating box for heating. After heating, the air spring chambers flow out of the heating box and pass under the temperature sensor. The temperature sensor transmits the temperature of the air spring chambers to the PLC controller. If the temperature is not within the required threshold range, the first robotic arm will place the air spring chambers with unqualified temperatures on the chain conveyor and collect them in the collection box for re-feeding and preheating.

The UV laser marking machine completes the marking work. S5. Detection: Industrial robot B drives the third manipulator to place the air spring chamber on the positioning pin D of the linear motor module d. When the air spring chamber passes under the industrial camera, the industrial camera transmits the image information to the PLC controller. The PLC controller determines whether the screw is embedded in the air spring chamber based on the image information.

[0019] S6. Weighing: The linear motor module e drives the fourth robot to grab the air spring chamber. If the PLC controller determines from the image information that the screw is not embedded, it is judged as a defective product. The fourth robot puts the defective product into the defective product inlet and collects it in the defective product box. The opening and closing cylinder extends, drives the door of the drive box to open, and the robot places the qualified air spring chamber detected by the industrial camera into the electronic scale for weighing.

[0020] S7. Unloading: The PLC controller determines whether the product is qualified based on the weight information fed back by the electronic scale. If the weight is not within the set threshold range, it is judged as a defective product. The fourth robot puts the defective product into the defective product inlet and collects it in the defective product box. The good product is placed on the belt conveyor to complete the unloading. The operator packs it on the packaging table for delivery or transfers it to the next process.

[0021] The beneficial effects of this invention are: The screw embedding device and method for the air spring chamber of the present invention integrates feeding, preheating, embedding, coding, detection, weighing and unloading into one unit, which saves a lot of time and effort, improves work efficiency, and at the same time ensures product quality.

A non-contact temperature sensor 204 is connected above the discharge end of the chain conveyor B201. In this embodiment, the non-contact temperature sensor 204 is a laser temperature sensor 204.

[0036] The first transfer mechanism 3 includes a linear motor module a301, which is connected to a bracket and is perpendicular to the feeding mechanism 1 and the preheating mechanism 2. A linear motor module b302 is connected to the slide of the linear motor module a301, and a first lifting cylinder is connected to the slide of the linear motor module b302. The power output end of the first lifting cylinder is connected to a base, and a first robotic arm is connected in parallel to the base. The first robotic arm corresponds vertically to each set of positioning pins A.

[0037] The second transfer mechanism 4 includes a linear motor module c401, which is connected to the machine base 5. The linear motor module c401 has a positioning pin C for placing the air spring chamber 18 on its slide. The coding mechanism 6 is a UV laser coding machine 601, which is connected to the machine base 5 on the side of the linear motor module c401.

[0038] Industrial robot A7 is located between preheating mechanism 2 and second transfer mechanism 4. The execution end of industrial robot A7 can drive the second manipulator to move to the discharge end of second transfer mechanism 4 to grab air spring chamber 18, and place air spring chamber 18 on the mold of injection molding machine 8, and then grab air spring chamber 18 and place it on second transfer mechanism 4. A chain plate conveyor 15 is provided between feeding mechanism 1 and preheating mechanism 2, and a collection box 16 is placed at the end of chain plate conveyor 15.

[0039] The third transfer mechanism 9 includes a linear motor module d901, and a positioning pin D for placing the air spring chamber 18 is connected to the slide of the linear motor module d901. The linear motor module d901 is perpendicular to the second transfer mechanism 4. The detection mechanism 11 includes a support 1101, and an industrial camera is connected to the support 1101.

[0043] In this embodiment, the first robotic arm, the second robotic arm, the third robotic arm, and the fourth robotic arm are all finger cylinders.

[0044] Example 2: This example is a further improvement on Example 1. The main improvement is that in Example 1, the box 1301 is in an open state during use, and impurities can easily fall onto the electronic scale 1302, resulting in inaccurate weighing results. In this example, the above-mentioned defects can be avoided. Specifically: Two doors 1303 are slidably connected to the top of the box body 1301, and two opening and closing cylinders 1304 are connected to the box body 1301, and the opening and closing cylinders 1304 drive the two doors 1303 to open or close respectively; in this embodiment, two doors 1303 are slidably connected to the top of the box body 1301 to prevent other impurities from falling onto the electronic scale 1302 and to ensure the accuracy of weighing.

[0045] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.

[0046] The specific working principle of this invention is as follows: Step 1, feeding: The operator manually or automatically places the air spring chamber 18 to be embedded in the screw 19 onto the positioning pin A on the chain conveyor A101. The chain conveyor A101 drives the air spring chamber 18 to move to the other end.

[0047] Step 2, Preheating: Driven by linear motor modules a301 and b302, the first robotic arm grasps multiple air spring chambers 18, moves them, and places them on the positioning pin B of the chain conveyor B201. The chain conveyor B201 drives the air spring chambers 18 into the heating box 203 for heating. After heating, they flow out of the heating box 203 and pass under the temperature sensor 204. The temperature sensor 204 transmits the temperature of the air spring chambers 18 to the PLC controller. If the temperature is not within the required threshold range, the first robotic arm will place the air spring chambers 18 with unqualified temperatures on the chain conveyor 15 and collect them in the collection box 16 for re-feeding and preheating.

[0048] Step 3, Embedded part: The operator manually or with a robotic arm grabs the screw 19 and places it in the mold of the injection molding machine 8 in advance. The industrial robot A7 drives the second robotic arm to place the preheated gripping air spring chamber 18 on the mold. Molten plastic is injected into the mold by the injection molding machine 8. After cooling, the screw 19 is wrapped in the mounting hole 1801 of the air spring chamber 18.

[0049] Step 4, coding: Industrial robot A7 drives the second robotic arm to grab the air spring chamber 18 embedded in the screw 19 and place it on the positioning pin C on the linear motor module c401. UV laser coding machine 601 completes the coding work. Step 5, Inspection: Industrial robot B10 drives the third manipulator to place the air spring chamber 18 on the positioning pin D of the linear motor module d901. When the air spring chamber 18 passes under the industrial camera, the industrial camera transmits the image information to the PLC controller. The PLC controller determines whether the screw 19 is embedded in the air spring chamber 18 based on the image information.

[0050] Step 6, Weighing: The linear motor module e1201 drives the fourth robotic arm to grab the air spring chamber 18. If the PLC controller determines from the image information that the screw 19 is not embedded, it is judged as a defective product. The fourth robotic arm puts the defective product into the defective product inlet 501 and collects it in the defective product box 502. The opening and closing cylinder 1304 extends, the drive box door 1303 opens, and the robotic arm places the qualified air spring chamber 18 detected by the industrial camera into the electronic scale 1302 for weighing.

[0051] Step 7, Unloading: The PLC controller determines whether the product is qualified based on the weight information fed back by the electronic scale 1302. If the weight is not within the set threshold range, it is judged as a defective product. The fourth robot arm puts the defective product into the defective product inlet 501 and collects it in the defective product box 502. The good product is placed on the belt conveyor 1401 to complete the unloading. The operator packs it on the packaging table 17 for delivery or transfers it to the next process.

[0052] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent transformations or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.

The good product is placed on the belt conveyor (1401) to complete the unloading. The operator packs it on the packing table (17) for delivery or transfers it to the next process.
