[0022] Specifically, the condenser 25 is arranged in an S shape inside the transverse clamping plate 5, so that the contact area with the cooling plate 24 can be increased, so that the cooling plate 24 absorbs more cold air, thereby cooling the electronic components.
[0023] In this embodiment: a cold conduction plate 24 is fixedly installed on the upper surface of the two horizontal clamping plates 5, a condenser 25 is arranged inside the two horizontal clamping plates 5, a refrigerator 26 is fixedly installed on the upper surface of the condensate tank 11, the surfaces of the cold conduction plate 24 and the condenser 25 are in contact with each other, the input end of the condenser 25 and the inside of the water pipe 13 are interconnected, the output end of the condenser 25 and the inside of the return pipe 15 are interconnected, and the inside of the water pipe 13 is interconnected with the inside of the return pipe 15 through the condenser 25.
[0024] Specifically, the upper surface of the cooling plate 24 is in direct contact with the lower surface of the electronic component, thereby ensuring the cooling effect.
[0025] In this embodiment: the output end of the first servo motor 4 is fixedly connected to the right end of the first forward and reverse screw rod 3, the output end of the second servo motor 9 is fixedly connected to the front end of the second forward and reverse screw rod 7, a water inlet is provided on the upper surface of the condensate tank 11, the condensate tank 11 is interconnected with the interior of the water supply pipe 13 through the first pump 12, and the condensate tank 11 is interconnected with the interior of the return pipe 15 through the second pump 14.
[0026] Specifically: When the condensate needs to be replaced after being used for a long time, the condensate can be replaced through the water inlet to ensure its refrigeration quality.
[0027] Working principle: When the utility model is in use, first the first servo motor 4 is started, driving the first positive and negative screw rod 3 to rotate clockwise, the first positive and negative screw rod 3 rotates clockwise, thereby driving the two horizontal clamping plates 5 to move in a direction close to each other, until the electronic component can be put down, and the electronic component is placed between the two horizontal clamping plates 5. At this time, the horizontal clamping plate 5 continues to move, thereby clamping the left and right sides of the electronic component. After the clamping is completed, the second servo motor 9 is started, driving the second positive and negative screw rod 7 to rotate clockwise, thereby driving the two vertical clamping plates 8 to move in a direction close to each other, thereby clamping the upper and lower sides of the electronic component. After the clamping is completed, the telescopic rod 16 is started, driving the welding head to move downward, thereby welding the surface of the electronic component. Before welding, the first pump 12 and the second pump 14 are started at the same time, and the first pump 12 and the second pump 14 are started at the same time.
