Description

Technical Field

[0001] The utility model belongs to the technical field of transformer production equipment, in particular to automatic transformer winding feeding equipment. Background Art

[0002] In the traditional transformer winding production process, the common feeding method used in factories is mainly semi-open manual feeding. This method involves the operator directly operating in front of and to the side of the equipment, placing the material in the fixture flow channel, and then waiting for the material to gradually move until it is completely received by the equipment, and then repeating the feeding process. This method has several significant shortcomings. First, because there are no protective doors or similar protective measures in front and to the side of the equipment, there are great safety hazards. The operator is vulnerable to accidental injuries during the feeding process, such as material ejection caused by sudden movement of mechanical parts or accidental blockage of the material flow channel.

[0003] Secondly, this traditional method requires continuous manual participation, which limits production efficiency and is labor-intensive. Long-term repetitive operations not only increase labor costs, but also easily cause operator fatigue, thus affecting the overall production quality and efficiency.

[0004] Therefore, in order to improve production safety, reduce production costs and improve efficiency, it is urgent to develop a new type of automated feeding equipment. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1 to Figure 3 The utility model provides a transformer winding automatic feeding device, comprising:

[0031] The chassis 1 comprises an upper case 11 and a lower case 12;

[0032] A workbench 2 is fixed in the chassis 1;

[0033] The feeding and loading mechanism 3 is installed on the workbench 2, and includes a positioning fixture 31 for placing the material tray 5, safety doors 32 installed on both sides of the positioning fixture 31, and a lifting mechanism 33 for lifting the material tray 5; the lifting mechanism 33 includes a lifting platform for carrying the material tray 5 and a driving mechanism that can drive the lifting platform to move longitudinally;

[0034] A manipulator 4 is arranged on the workbench 2, and is used to grab the material in the material tray 5 and transfer it to the material discharge direct vibration device 8 or to grab the empty tray 6 to the empty tray delivery port 7;

[0035] The material discharging direct vibration device 8 is used to receive the material placed by the robot 4 and transfer the material;

[0036] The PLC controller is used to control the operation of the entire device, including receiving feedback signals from various sensors and controlling the movement of the manipulator 4 and the position adjustment of the lifting mechanism 33 according to these signals.

[0037] The automatic transformer winding feeding equipment provided by the utility model realizes the automated operations of material loading, grabbing, transferring and unloading by arranging a manipulator, a material feeding and loading mechanism, a material discharging direct vibration device and a PLC controller, thereby effectively improving production safety and avoiding the potential safety hazards caused by manual operation; at the same time, it reduces labor input and reduces production costs; in addition, the operating efficiency of the automated equipment is higher than that of manual operation, thereby improving production efficiency.

[0038] Therefore, the equipment will adopt automated tray feeding, automatic lifting and robotic handling systems, which not only ensures operational safety, but also significantly improves production efficiency and reduces waste of manpower and material resources.

[0039] In one embodiment of the present application, the manipulator 4 includes a suction cup device 42 and a moving mechanism 41 for driving the suction cup device 42 to move horizontally or vertically; the suction cup device 42 is provided with a plurality of suction nozzles 421 for sucking tray materials or empty trays. The suction cup device can suck a plurality of tray materials or empty trays at the same time through a plurality of suction nozzles, and the moving mechanism drives the suction cup device to move, thereby realizing the rapid grasping and transfer of materials and empty trays, and improving the efficiency of loading and unloading.

[0040] In one embodiment of the present application, the discharge direct vibration device 8 includes a discharge flow channel 81 and a sensor disposed at the end of the discharge flow channel 81 for detecting whether there is material in the discharge flow channel 81. Timely detection of whether there is material in the discharge flow channel prevents equipment blockage caused by poor discharge, thereby ensuring continuous and efficient operation of the equipment.

[0041] In one embodiment of the present application, the feeding and loading mechanism 3 is provided with a material tray in position sensor 34, which is used to sense whether the material tray has reached a preset height and stop lifting when the preset height is reached. The lifting height is accurately controlled so that the material tray reaches the optimal material picking position, which facilitates the manipulator to quickly and accurately grab the material, thereby improving the loading efficiency and the grabbing success rate.

[0042] In one embodiment of the present application, the feeding and loading mechanism 3 is also provided with a tray limit sensor 35. When all the material trays are taken out, the lifting mechanism triggers the upper limit sensor, and the PLC controller controls the lifting mechanism to descend to the initial height. When the material trays are taken out, the lifting mechanism is automatically controlled to reset without manual intervention, thereby improving the automation degree and continuous production capacity of the equipment.

[0043] In one embodiment of the present application, the number of material trays that can be accommodated in the feeding and loading mechanism 3 is 18 to 25, which increases the storage capacity of the material trays, reduces the loading frequency, and further improves the working efficiency of the equipment.

[0044] In one embodiment of the present application, the safety door 32 is equipped with a foolproof door sensor, and the safety door 32 must be closed and the closed state is confirmed by the foolproof door sensor before the device can be operated. This ensures the safety of the device during operation, prevents personnel from mistakenly entering the working area, and avoids safety accidents.

[0045] In one embodiment of the present application, the outer surface of the chassis 1 is provided with a user operation interface 9, through which the user inputs operation instructions to control the start, stop and reset of the entire device. This facilitates the user to achieve one-touch control, including controlling the start, stop and reset of the device, and at the same time, the user can intuitively observe the working status of the device, including the cumulative amount and time of the material, etc., thereby improving the human-computer interactivity and visual management level.

[0046] In one embodiment of the present application, the driving mechanism is a motor, a cylinder or a hydraulic cylinder, which increases the diversity and flexibility of the driving mode, and a suitable driving mode can be selected according to actual production needs to optimize equipment performance.

[0047] In one embodiment of the present application, universal wheels 10 are provided at the bottom of the chassis 1 to facilitate the movement of the chassis 1 .

[0048] Among them, the working process of the utility model is as follows:

[0049] First, make sure the robot stays at the safe point (if it is not at the safe point, you can move it to the safe point manually), click the reset button on the touch screen to reset the device first, and the touch screen will display the words after the reset is completed. Then click the external start button, and the lifting mechanism will move to the discharge position. Open the safety anti-fool door, put in the tray filled with materials, and close the safety anti-fool door after confirming that the tray is placed. After the safety anti-fool door is closed, the anti-fool sensor has a signal to operate the device, otherwise it cannot be operated, and then close the door of the device. There is a start button on the outside of the device. At this time, press the start button, and the device starts to work. The tray lifting mechanism starts to lift the tray upward to load the material. When the tray reaches the range of the tray sensor, the tray lifting mechanism stops when the sensor has a sensing signal, and the sensing signal is fed back to the PLC controller. At this time, the PLC controller will send a material-picking instruction to the robot. The manipulators are arranged vertically from right to left in sequence. The suction nozzles suck the material and then move to the top of the straight vibration flow channel of the discharge straight vibration mechanism. There is a sensor at the end of the flow channel. When no material is sensed, the PLC controller sends a signal to the manipulator to allow the material to be discharged. The manipulator puts the material horizontally into the discharge flow channel, and then the material flows to the winding machine for winding. The manipulator returns to a safe point and waits for the PLC controller to send a signal to allow the material to be taken. As mentioned above, the manipulator sucks the material from the tray vertically in sequence, and then puts it horizontally into the discharge flow channel until a tray of material is taken. After the material in the tray is taken, the manipulator moves vertically to the middle of the tray, sucks the empty tray, moves to the empty tray delivery port and puts the empty tray in. The empty tray will flow out of the equipment. Then the robot will move to the safe point and wait for the PLC controller to send a signal to allow material to be taken. At this time, the tray in place sensor above the tray lifting mechanism does not sense the presence of a tray, and the tray lifting mechanism will continue to lift upward until the tray in place sensor senses the tray, then the tray lifting mechanism will stop moving, and the PLC controller will send a command to the robot to start a new tray of material to be taken and loaded. After the empty tray of the last tray of material is taken away by the robot and the robot returns to the safe point, the tray lifting mechanism will be sensed by the tray limit sensor when it is lifting upward, and feedback will be given to the PLC controller, triggering the tray lifting mechanism to return to the origin for the next round of loading.
