The elastic sheet assembling equipment comprises a workbench, a support feeding device, a jig conveying device, elastic sheet press-fitting devices, a turnover device and a detection and discharging device, wherein the support feeding device, the jig conveying device, the elastic sheet press-fitting devices, the turnover device and the detection and discharging device are fixed to the workbench; the support feeding device, the elastic sheet press-fitting devices, the turnover device and the detection and discharging device are connected with corresponding stations of the jig conveying device separately; and the multiple elastic sheet press-fitting devices are located on the front side and the rear side of the turnover device separately. According to the production system, through the arrangement of the support feeding device, the jig conveying device, the elastic sheet press-fitting devices, the turnover device and the detection and discharging device, automatic machining and circulation of microswitch elastic sheets and supports are achieved, and the automation degree of the whole equipment is improved.

Description

technical field [0001] The invention relates to the field of micro switches, in particular to a micro switch automatic production system and a production process. Background technique [0002] The micro switch is a contact mechanism with a small contact interval and a quick action mechanism, which performs a switching action with a specified stroke and a specified force. It is covered with a casing and has a drive rod on the outside. Small, hence the name micro switch, also called sensitive switch. The external mechanical force acts on the action reed through the transmission elements (press pins, buttons, levers, rollers, etc.). Tap to quickly connect or disconnect. The assembly of the micro switch shrapnel and the micro switch bracket has an important influence on the performance of the micro switch. The quality of shrapnel and bracket assembly directly affects the sensitivity, accuracy and service life of the micro switch. Therefore, for the micro switch, the assembly...

Problems solved by technology

[0003] Chinese invention patent application (publication number CN210997358U, publication date: 202007144) discloses an assembly device for micro switch terminals and end caps, which solves the complex and low assembly efficiency of existing micro switch terminals and end caps technical problem, it is equipped with a workbench, and the two sides of the workbench are respectively equipped with a terminal vibration plate and an end cover vibration plate. There is a terminal slideway, and a detection mechanism is installed above the terminal slideway. The detection mechanism uses a detection cylinder to drive the probe to move. A positioning cylinder is provided under the terminal slideway. The output end of the positioning cylinder is provided with a moving shaft that matches the terminal seat. There is a horizontal push mechanism under the positioning cylinder, and the horizontal push mechanism drives the positioning cylinder to move in the horizontal direction through the push cylinder; the discharge port of the end cover vibrating plate is provided with an end cover direct vibration slideway, and an end cover is provided at the exit of the end cover direct vibration slideway. Cover positioning seat, the top of the end cover positioning seat is provided with a grabbing mechanism

[0004] The existing technology has the following deficiencies: 1. When assembling the shrapnel of the micro switch, each process is manually completed on a single workbench, and then the product flow is sent to the next workbench through the conveyor line for the next process process, and finally completed The entire assembly process of the micro switch shrapnel; and each process requires manual participation and auxiliary feeding flow, which affects the processing efficiency of the entire device and results in a low degree of automation of the entire equipment

2. When circulating the micro switch shrapnel positioning jig, first use the air claw hand to grab the empty positioning jig at the end of the conveyor belt, and then move the moving device to drive the air claw hand to move to the initial end of the conveyor belt to complete the positioning jig Circulation; while the air claw hand grasps the positioning fixture cycle, it needs three steps: the air claw hand grasps up, the moving device moves horizontally, and the air claw hand moves down to release, resulting in more steps when the positioning fixture is cycled, which is not conducive to positioning. with fast cycle

3. When loading the shrapnel belt of the micro switch, first place the shrapnel belt on the conveyor belt, and then drive the shrapnel belt to move along the limit device to the punching and bending process through the friction between the conveyor belt and the shrapnel belt. The shrapnel belt itself is thinner and lighter in weight, and the friction between the conveyor belt and the shrapnel belt is also small, that is, the driving force provided by the conveyor belt to the shrapnel belt is small; The limit resistance of the limit device; when the shrapnel belt is deformed due to inaccurate manufacturing or transportation impact, the friction resistance between the shrapnel belt and the limit device will further increase; when the friction between the shrapnel belt and the limit device When the resistance is greater than the driving force provided by the conveyor belt, the shrapnel belt will be stuck between the limit devices, causing the shrapnel belt to fail to load normally

4. When punching and bending the shrapnel of the micro switch, first use the punching device to punch a single shrapnel from the shrapnel belt, and then use the bending device to bend the single shrapnel to complete the punching and bending process of the shrapnel ; and in this way of processing, the punching process and bending process of the shrapnel are carried out separately, that is, two steps of punching and bending are required, resulting in an increase in the processing steps of the shrapnel; at the same time, when the punching and bending are performed separately, it is necessary to The punching device and the bending device are respectively set up, which also increases the number of equipment and the space occupied by the equipment
