In the prior art, when workers produce air conditioner base plates for welding, the base feet of the base plates are easy to be welded, so that the produced air conditioner base plates need to be inspected one by one, unqualified products are reworked again or the products are unavailable, production time and manpower resources are excessively consumed, negligence can occur, and the situations of production material waste and the like are caused. Chinese patent CN206028993U discloses a fool-proof device for spot welding of auto parts, including material frame, spot welder, flexible door, first photoelectric sensor, second photoelectric sensor, material temporary storage frame, counting sensor and programmable control chip, wherein first photoelectric sensor is used for detecting whether there is the material on the operation panel, however the waste residue that flies to splash among the spot welding process probably covers the response that leads to the sensor on the photoelectric sensor and appears the mistake, and then influences the normal clear of spot welding process.
Disclosure of Invention
The utility model aims at the problem that prior art exists, provide one kind and use photoelectric sensor and pressure sensor cooperation, not only can avoid air conditioner chassis footing to leak and weld, still can avoid a certain sensor to receive external influence and lead to spot welding a spot welding device on air conditioner chassis wrong.
In order to achieve the above object, the utility model adopts the following technical scheme:
a spot welding device of an air conditioner chassis comprises a spot welding machine, a photoelectric sensor, a pressure sensor, a controller and a clamp; the clamp is positioned on two sides of the spot welder, and the photoelectric sensor, the pressure sensor and a switch of the spot welder are electrically connected to the controller. When using this spot welding device to weld air conditioner chassis, be fixed in the anchor clamps of both sides with air conditioner chassis between, place the footing on chassis respectively in the welding point on left and right sides both sides, the footing can cover photoelectric sensor this moment, and pressure sensor has sensed pressure variation simultaneously, pressure sensor has set up the threshold value in advance, and this threshold value is the weight scope of footing, when pressure variation is in this threshold value scope, can regard as to place the footing, does not then regard as not placing the footing in this threshold value scope. When the photoelectric sensor and the pressure sensor sense the feet, the spot welder can be started through the controller to weld the air conditioner chassis and the feet, and if any one of the photoelectric sensor and the pressure sensor does not sense the feet, the spot welder cannot be started to weld.
Preferably, the photoelectric sensor is positioned in the clamp and used for sensing whether feet of the air conditioner chassis are placed or not, and when the photoelectric sensor is covered, the feet of the air conditioner chassis are prevented from being placed above the photoelectric sensor.
Preferably, the pressure sensor is located below the spot welder and used in cooperation with the photoelectric sensor, and when feet of the air conditioner chassis are placed, the pressure sensor can sense pressure changes within a preset threshold range.
Preferably, the number of the pressure sensors is one or more, namely two pressure sensors can be respectively placed below two sides of the spot welding machine, and one pressure sensor can be placed below the spot welding machine.
Preferably, the controller is a PLC controller for connecting the sensor and the switch of the spot welding machine.
Preferably, the two sides of the clamp are provided with slide rails, so that the clamp can slide on the slide rails according to the length of a placed product, and the distance between the two slide rails is controlled, thereby placing products with different lengths.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the photoelectric sensor, the pressure sensor and the controller are additionally arranged on the original spot welding device, so that the bottom foot of the chassis is prevented from being welded in a missing manner in the process of producing the air conditioner chassis, the supervision personnel and the rework time are saved, and the waste of production materials is avoided;
(2) the photoelectric sensor and the pressure sensor are used in a matched mode, and the situation that when a certain sensor breaks down, the spot welding process is affected or spot welding is wrong is avoided.

Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
