Description

Technical Field

[0001] This utility model relates to the field of gasket retesting technology, and in particular to an electrically driven automatic gasket retesting device. Background Technology

[0002] The automotive industry is one of the most important application areas for rubber gaskets. Rubber gaskets are used in the manufacture of key components such as car tires, shock absorbers, and seals, which can significantly improve vehicle comfort and safety.

[0003] There are currently three main types of similar inventions on the market:

[0004] Application 1: An automatic gasket selection device (CN214732525U)

[0005] This application relates to an automatic gasket selection device, specifically in the field of automotive parts technology. The device includes a body with at least one set of gasket storage mechanisms. Each storage mechanism includes a support column and several storage racks mounted on the support column for accommodating gaskets of different sizes. The body also includes a pushing mechanism for ejecting gaskets of the required size from their corresponding storage racks. This application, by using storage racks and a pushing mechanism to eject gaskets of the required size from the racks in multiple storage mechanisms, automatically removes the gaskets from the body, thus providing the advantage of easy removal of gaskets of the appropriate size.

[0006] Application 2: Sheet Selection Device (CN209939823U) This application relates to the field of automatic sheet selection technology and discloses a sheet selection device. The sheet selection device includes: a substrate, the substrate being provided with a pushing path having a discharge position; a pushing unit; a plurality of feeding units, the plurality of feeding units being arranged at intervals along the pushing path on the substrate; a control unit; the control unit is capable of receiving an instruction to select a sheet of a required specification, and controlling the feeding unit corresponding to the required specification sheet among the plurality of feeding units to supply the required specification sheet to the pushing path according to the instruction, the pushing unit being capable of pushing the required specification sheet along the pushing path to the discharge position. In this way, the required specification sheet can be automatically, efficiently and accurately selected, reducing production costs and the sheet selection error rate compared to manual sheet selection.

[0007] Application 3: An intelligent material rack device for automatic pad selection and retesting (CN111071767A) This invention discloses an intelligent material rack device for automatic pad selection and retesting, including a base frame assembly. The material rack device further includes a servo assembly, a tray assembly, a retesting and alignment assembly, and several hopper assemblies. The servo assembly, the retesting and alignment assembly, and the hopper assemblies are all mounted on the base frame assembly, and the tray assembly is mounted on the servo assembly. The pad selection and retesting process of this invention is completed automatically, effectively improving the automation level of the entire production line. At the same time, the pad selection and retesting process of this invention does not require direct human intervention, effectively preventing the problem of pad selection and retesting errors caused by manual pad selection errors.

[0008] The main drawbacks of the existing technology are as follows: the selection of gaskets adopts an up-and-down lifting method, the retesting of gaskets cannot be automated and manual intervention is still required, and each feeding unit is equipped with a pushing unit, which increases the cost of the equipment; the retesting of gaskets only uses a single probe for measurement, resulting in inaccurate measurement accuracy and causing rework of the electric drive after assembly.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0038] This utility model discloses an automatic device for retesting electrically driven gaskets, referenced... Figures 1-9 The system includes a gasket 1, a frame 2, a gasket feeding frame unit 3, a gasket feeding and conveying unit 4, a gasket retesting unit 5, a standard parts unit 6, an NG material frame 7, a support 8, and a leveling mechanism 9. The frame 2 is leveled and fixed to the ground using the leveling mechanism 9. In this embodiment, eight leveling mechanisms 9 are used to complete the leveling and fixing. The support 8 is placed above the frame 2 and fixed. The gasket feeding frame unit 3 is installed above the support 8. The number of gasket feeding frame units 3 is set according to the customer's technical requirements. This invention can be used for two or more types of gaskets 1 with different diameters. Gasket 1 is selected and placed into gasket feeding frame unit 3. Gaskets of different thicknesses are selected mainly by gasket picking and feeding conveying unit 4, which is placed above and fixed to frame 2. After selecting gasket 1, gasket picking and feeding conveying unit 4 conveys it to gasket retesting unit 5, which is placed above and fixed to frame 2. For NG gasket 1, it is placed into NG material frame 7 by an external robot arm, which is placed above frame 2. To verify the reliability of the equipment and retest the accuracy of the gaskets, standard parts unit 6 is placed above frame 2 and fixed.

[0039] The gasket feeding frame unit 3 includes a gasket 1, a feeding sleeve 3-1, a pad block 3-2, a sensor bracket 1 3-3, a sensor 1 3-4, a sensor 2 3-5, a connecting plate 1 3-6, a slider 1 3-7, a slider 2 3-8, a slide rail 3-9, an indicator light mounting bracket 3-10, a nameplate bracket 3-11, a nameplate 3-12, an indicator light 3-13, a gasket feeding plate 3-14, a counterweight 3-15, and a plunger 3-16. Its function is to move the slide rail 3-9 by inserting the positioning pin 4-9 on the gasket feeding conveyor unit 4 into the oblong hole of the slide rail 3-9. The gasket feeding plate 3-14 is placed in the slot of the slide rail 3-9, and the gasket feeding plate 3-14 moves a gasket 1 into the large hole of the slider 2 3-8, whereby the gasket 1 falls into the feeding slot of the gasket feeding conveyor unit 4. Place slider 2 3-8 above support 8. Place slider 1 3-7 above slider 2 3-8 and fix it in place. After slider 2 3-8 is installed, place the gasket feeding plate 3-14 into the slot of slide rail 3-9.

This ensures that slide rail 3-9 will not fall or slide out when there is no power. Place shim 3-2 on the feeding sleeve 3-1. It is mainly used to adjust the feeding sleeve 3-1 and the shim. The height between the feeding plates 3-14 is adjusted to ensure that only one pad 1 can be moved at a time. The feeding sleeve 3-1 is then placed above and fixed to the slider 3-7. The sensor bracket 3-3 is installed above the connecting plate 3-6. The distances between the sensors 3-4 and 3-5 and the pad 1 are adjusted and fixed into the mounting holes of the sensor bracket 3-3. Sensor 3-4 is primarily used to detect whether the feeding sleeve 3-1 of the pad feeding frame unit 3 is full of pads 1. Sensor 3-5 is used to alarm that the pads 1 in the pad feeding frame unit 3 are running out and manual feeding is required. The nameplate bracket 3-11 is installed on the front of the slider 3-7. A nameplate 3-12 is placed above the nameplate bracket 3-11. The nameplate 3-12 is mainly used for manual identification of the model, size, and thickness of the pads used in each pad feeding frame unit 3 to prevent incorrect placement of pads 1. Install the indicator light mounting bracket 3-10 onto the front of slider 3-7. Install indicator light 3-13 inside the hole of the bracket 3-10. Indicator light 3-13 illuminates based on the required shim thickness calculated from the previous workstation. Indicator light 3-13 turns off after shim 1 is removed. Place counterweight 3-15 into the discharge sleeve 3-1 filled with shims 1. Counterweight 3-15 prevents shims 1 from getting stuck in the discharge sleeve 3-1. Install plunger 3-16 onto connecting plate 3-6. When subjected to external force, plunger 3-16 compresses, causing slide rail 3-9 to move. When not subjected to external force, slide rail 3-9 remains stationary.
