Description

Technical Field

[0001] This utility model relates to the field of telescopic conveyor manufacturing, and in particular to a precision repair device for connecting parts of telescopic belt conveyors. Background Technology

[0002] Telescopic belt conveyors are ordinary belt conveyors with added telescopic mechanisms, allowing the belt conveyor to extend and retract freely in the length direction. Users can adjust the buttons according to their requirements to control the length of the conveyor at any time. They are mainly used in vehicle loading and unloading and material handling systems with telescopic requirements.

[0003] In the production process of telescopic belt conveyors, connectors are needed to connect different components. For example, Chinese patent CN217208889U discloses a sheet metal connector that facilitates connection, which includes a first connector, a second connector and a third connector fixedly connected to both sides of the first connector, and an auxiliary mechanism provided on the upper side of the second connector and the third connector. The auxiliary mechanism includes a fixing block fixedly connected to the upper side of the second connector.

[0004] Such connectors are commonly used as parts in telescopic belt conveyors, but burrs may be present at the openings during the manufacturing process. Traditionally, these burrs are removed by hand filing, which has the following drawbacks:

[0005] Firstly, frequent adjustments to the connectors are required, resulting in high labor intensity;

[0006] Secondly, the close contact between operators and the connecting parts poses a safety hazard.

[0007] Third, filing results in a large amount of debris, creating a harsh working environment and low processing efficiency. Utility Model Content

[0143] Working principle and usage:

[0144] Step 1, Pre-setting:

[0145] Place the corresponding shaped connector 701 into the vibratory feeder 201; and adjust the movable limit block according to the shape of the connector 701 to fit the shape of the connector 701. Adjust the size of the screening rod 303 and the bolt to fit the size of the screw hole of the connector 701.

[0146] Press the start switch to test the power supply.

[0147] Press the adjustment switch, and the PLC controller outputs a signal to the screw jack 205. The screw jack 205 drives the second limit baffle 204 to move in an orderly manner, thereby adjusting the distance between the first limit baffle 203 and the second limit baffle 204.

[0148] Pressing the fixed switch causes the PLC controller to output a signal to the push rod motor 602 and the electric telescopic rod 603. The push rod motor 602 drives the "L"-shaped limit hook to move, thereby fixing the storage base plate of the storage mechanism 604. The electric telescopic rod 603 drives the movable base plate to move upward.

[0149] The second step is to use:

[0150] Pressing the precision switch activates the PLC controller, which outputs a signal to the vibratory feeder 201 and the conveyor belt structure 202. The vibratory feeder 201 and conveyor belt structure 202 then start, causing the connector 701 to move below the electric telescopic rod 501. The distance sensor module 1 outputs the collected signal to the PLC controller, which in turn outputs a signal to the push rod motor 206, the electric telescopic rod 501, the push rod motor 502, and the gripper motor 503.

[0151] Push rod motor 206 drives the limiting structure 207 to move, correcting the position of connector 701. Push rod motor 502 and gripper motor 503 start to grip the connector; electric telescopic rod 501 starts after a delay and transfers connector 701 into the screening box structure.

[0152] Distance sensor module 2 outputs the collected signals to the PLC controller, and the PLC controller outputs signals to push rod motor 2 301, push rod motor 6 306, and lead screw stepper motor 1 304.

[0153] Push rod motor 2 301 drives the screening rod 303 to move in an orderly manner to determine the position of the connector 701. Push rod motor 6 306 starts after a delay, first fixing the connector 701, and then the screening rod 303 disengages from the connector 701.

[0154] The lead screw stepper motor 304 starts, moving the connector 701 below the grinding mechanism. At the same time, the connector 701 is fixed in another unloaded area of ​​the screening box structure.

[0155] The distance sensor module 3 outputs the collected signal to the PLC controller, and the PLC controller outputs the signal to the servo motor 308 and the push rod motor 307. The servo motor 308 drives the frustum-shaped grinding head to rotate, and the push rod motor 307 drives the frustum-shaped grinding head to move down in an orderly manner to grind the screw hole of the connector 701.

[0156] After grinding, the PLC controller outputs signals to the electric telescopic rod 504, push rod motor 505, and gripper motor 506. Push rod motor 505 and gripper motor 506 grip the connector 701, and the electric telescopic rod 504 moves the connector 701 away from the screening box structure, then places it onto the calibration plate 401. The distance sensor module 5 outputs the collected signal to the PLC controller, which outputs a signal to the push rod motor 402. Push rod motor 402, after a delay, moves the calibration bolt 403 upwards to detect the connector 701. If the hole is smaller than the standard, the connector is pushed out of the calibration plate 401, and the output signal of the distance sensor module 5 changes.

[0157] The third step is storage:

[0158] The distance sensor module four outputs the collected signals to the PLC controller, and the PLC controller outputs signals to the lead screw stepper motor two 507, the electric telescopic rod three 508, the stepper motor 509, the gripper motor three, and the lead screw stepper motor three 601.

[0159] Electric telescopic rod 3 (508), stepper motor 509, and gripper motor 3 grasp the connector 701 and adjust the orientation of the connector 701. Lead screw stepper motor 2 (507) transfers the connector 701 to the limit rod 3. When one layer is full, electric telescopic rod 4 (603) moves down one unit distance.

[0160] When a row of storage mechanisms 604 is fully loaded, the lead screw stepper motor 601 drives the positioning box structure to move, so that the unloaded positioning box structure is located below the mounting plate. In this way, the storage of all connectors 701 is completed.

[0161] Example 2: Based on Example 1, a dustproof curtain is added to the side of the load-bearing plate 105 to improve the working environment.
