[0002] An evaporator is an important component used in refrigeration and air conditioning systems. Its main function is to convert the refrigerant (usually a refrigerant) from a liquid state to a gaseous state. This process is completed by absorbing heat, thereby achieving a refrigeration effect. Evaporators are widely used in various refrigeration devices, such as refrigerators, air conditioners, refrigerated trucks, etc.

[0025] Such as Figures 1 to 4As shown in the figure, an evaporator laser welding jig includes a base 1. In the middle of the top surface of the base 1, a profiling mechanism base 2 is fixedly connected. Above the profiling mechanism base 2, a profiling mechanism 3 is provided. A pressing plate 5 is pressed on the top surface of the profiling mechanism 3. On the top surface of the base 1, a demoulding mechanism 6 is provided for controlling the vertical movement of the profiling mechanism 3. On the surface of the profiling mechanism base 2, an opening cover assembly 7 is installed for controlling the movement of the pressing plate 5. On the top surface of the base 1, a rotary pressing mechanism 4 is also provided for limiting the position of the pressing plate 5. More specifically, first, the operator takes out the pressing plate 5, then places the product into the profiling mechanism 3, then covers the pressing plate 5, presses the start button, the rotary pressing mechanism 4 rotates and presses the pressing plate 5 downwards, so that the products are fitted together for convenient welding. After welding is completed, the rotary pressing mechanism 4 releases the pressing plate 5, the demoulding mechanism 6 drives the profiling mechanism 3 to move downwards, and pushes the product out of the inside of the profiling mechanism 3. The opening cover assembly 7 can assist in driving the pressing plate 5 to rise, thus facilitating material taking.

[0026] The rotary pressing mechanism 4 includes a first electric push rod 401, and the first electric push rod 401 is fixedly installed on the top of the base 1. The end of the telescopic end of the first electric push rod 401 is fixedly installed with a motor 402. The output end of the motor 402 is fixedly connected with a rotating shaft 403. The end of the rotating shaft 403 is fixedly connected with a pressing block 404. It should be noted that by running the motor 402, the rotating shaft 403 and the pressing block 404 are driven to rotate, so that the pressing block 404 rotates to the upper side of the pressing plate 5, and then the first electric push rod 401 drives the motor 402 to descend, driving the rotating shaft 403 and the pressing block 404 to descend, so that the pressing block 404 presses the top surface of the pressing plate 5 to press and limit the pressing plate 5.

[0027] The demoulding mechanism 6 includes a second electric push rod 601, and the second electric push rod 601 is fixedly installed on the top surface of the base 1. The telescopic end of the second electric push rod 601 is fixedly connected with a lower docking plate 602. Both the left and right sides of the profiling mechanism 3 are fixedly connected with upper docking plates 603, and the upper docking plate 603 and the lower docking plate 602 are fixedly connected by bolts. A top-out groove 605 is formed through the middle of the profiling mechanism 3. A top-out block 604 is fixedly connected to the top surface of the profiling mechanism base 2, and the surface of the top-out block 604 is slidably connected to the inner wall of the top-out groove 605. More specifically, by running the second electric push rod 601, its telescopic end is shortened, thereby driving the lower docking plate 602 and the upper docking plate 603 to descend, and then driving the profiling mechanism 3 to descend. The top-out block 604 will slide along the inner wall of the top-out groove 605, pushing the product inside the profiling mechanism 3 upwards, so that the profiling mechanism 3 and the product are separated from each other.

[0028] A pressure sensor 606 is fixedly installed on the top surface of the profiling mechanism base 2. It should be noted that when the profiling mechanism 3 continuously descends under the action of the demolding mechanism 6 and finally contacts the pressure sensor 606, the pressure sensor 606 will detect the pressure at this time and immediately feedback to pause the operation of the second electric push rod 601, thereby controlling the lowest position of the descent of the profiling mechanism 3.

[0029] The lid opening assembly 7 includes a third electric push rod 701, and the third electric push rod 701 is fixedly installed on the surface of the profiling mechanism base 2. The telescopic end of the third electric push rod 701 is fixedly connected to a connecting column 702, and the top end of the connecting column 702 contacts the bottom surface of the pressing plate 5. A sliding hole 703 is penetrated through the surface of the profiling mechanism 3, and the inner wall of the sliding hole 703 is slidably connected to the surface of the connecting column 702. A guide post 704 is fixedly connected to the top surface of the profiling mechanism 3, and the guide post 704 is slidably connected to the sliding block of the pressing plate 5. More specifically, by operating the third electric push rod 701, the connecting column 702 is driven to move upward, and the pressing plate 5 is pushed along the surface of the guide post 704 by the connecting column 702, so as to control the pressing plate 5 to rise, thereby expanding the gap between the profiling mechanism 3 and the pressing plate 5 and facilitating the taking of products.

[0030] The number of the rotary pressing mechanisms 4 is four groups, and the four groups of rotary pressing mechanisms 4 are respectively located at the four corners of the top surface of the base 1. It should be noted that by setting the four groups of rotary pressing mechanisms 4, the four corners of the pressing plate 5 are pressed and limited, so that the profiling mechanism 3 and the pressing plate 5 are kept stable.

[0031] In summary: First, the operator takes out the pressing plate 5, then puts the product into the profiling mechanism 3, then covers the pressing plate 5, presses the start button, the rotary pressing mechanism 4 rotates and presses the pressing plate 5 downward, so that the products are fitted together for convenient welding. After welding is completed, the rotary pressing mechanism 4 releases the pressing plate 5, the demolding mechanism 6 drives the profiling mechanism 3 to move downward, and the product is pushed out from the inside of the profiling mechanism 3.
