[0023] Example: Figures 1 to 5 As shown: A PCB aluminum substrate cooling device capable of intelligently adjusting temperature, the cooling device comprises a box body 1, a supporting mechanism 2, a first moving part 3 and a second moving part 4. Figure 1 As shown: the box 1 is distributed on the left and right, and the interior is a cavity structure; it is used to place the PCB board for cooling. Preferably, the bottom of the box 1 is provided with support legs 11, so that it is convenient to form a stable support. The front of the box 1 is provided with a door 12; one side of the door is hinged to the box through a hinge, so that it is convenient to form an opening and closing structure for loading and unloading, while ensuring sufficient sealing effect. The rear side of the box is provided with an air vent. Figure 2 As shown: an adjusting screw 13 is provided on one side of the support leg 11, and a mounting hole 14 is provided on one side of the box body 1, and a threaded rotation connection is maintained between the adjusting screw 13 and the mounting hole 14. The purpose of such a setting is to achieve horizontal support adjustment of the box body through the rotation effect of the adjusting screw, thereby ensuring that the box body is always in a horizontal working state.

[0024] like Figure 3As shown: In this embodiment, the support mechanism 2 includes a support plate 21, a cylinder 22, and a clamping plate 23. The support plates 21 are two symmetrically distributed on the left and right sides, and are both arranged on the side wall of the inner cavity of the box body 1, and the support plates themselves extend forward and backward. The cross section of the support plate 21 is a concave structure, and the PCB substrate workpiece is placed horizontally between the two support plates 21. The cylinder 22 is arranged on the outside of the support plate 21, and the output end passes through the side wall of the support plate 21. One end of the clamping plate 23 is connected to the output end of the cylinder 22 and is located in the concave inner cavity of the support plate 21. It can move up and down to complete the loading and unloading operations of the PCB substrate workpiece; the lower end surface of the clamping plate 23 is also bonded with an elastic pad 24. With such a setting, the structural design is reasonable, and the concave structure of the support plate is convenient for forming a slide rail structure to complete the loading of the PCB board. In the initial state, the cylinder is contracted and the clamping plate is at the highest point of the stroke position. An air pump is provided on one side of the box body to drive the cylinder to work. Then the staff starts the extension of the cylinder, which will drive the clamping plate and the elastic pad to complete the clamping and fixing operation of the PCB board.

[0025] like Figure 3As shown: In this embodiment, the first moving member 3 includes a first screw rod 31, a first guide rod 32, a first motor 33 and a connecting plate 34. The first screw rod 31 is vertically distributed and arranged between the upper end face and the lower end face of the box body 1, and passes through the support plate 21, and does not interfere with the inner cavity of the support plate 21. The support plate 21 and the first screw rod 31 are matched by keyways to maintain relative rotation but not relative movement. The upper and lower parts of the first screw rod 31 are provided with a rotating part 35 with opposite thread rotation directions; such an arrangement can drive the two connecting plates connected to the rotating plate to move closer or farther synchronously. The first guide rod 32 is vertically distributed and arranged in the inner cavity of the box body 1, and remains parallel to the first screw rod 31. The first motor 33 is arranged on the box body 1 through a bracket, and the output end is connected to the first screw rod 31; the first motor adopts a servo control motor. The connecting plates 34 are two, which are distributed up and down, and are respectively connected to the upper and lower rotating parts 35 of the first screw rod 31 in rotation, and the connecting plates 34 also pass through the first guide rod 32; the first screw rod 31, the first guide rod 32, the first motor 33 and the two connecting plates 34 are two groups that are matched and installed and distributed left and right. That is, the two first screw rods are located at the front side of the box body, and the two first guide rods are located at the rear side of the box body. The upper left and right connecting plates are symmetrically positioned, and the lower left and right connecting plates are also symmetrically positioned. In this way, in the initial state, the distance between the upper two connecting plates and the lower two connecting plates from the centrally distributed PCB board is the largest. When the staff starts the first motor to rotate forward, the first screw rod rotates clockwise, which will drive the upper and lower connecting plates to move along the first screw rod, specifically, the upper and lower connecting plates are close to each other, so that the closer the connecting plate drives the cooling pipe to the PCB board, the stronger the cooling effect on the PCB board is, thereby achieving the purpose of intelligent temperature regulation. On the contrary, the first motor reverses and drives the upper and lower connecting plates to move away from each other. Thus, the further the connecting plates drive the cooling tubes to move away from the PCB, the weaker the cooling effect on the PCB.

[0026] like Figure 3 and Figure 4 As shown: In this embodiment, a cooling pipe 5 is further provided between the connecting plates 34 symmetrically distributed on the left and right sides, and the two cooling pipes 5 are symmetrically distributed up and down; the input end of the cooling pipe 5 is connected to the external cold air source through a fan 51, and the fan 51 adopts a variable frequency fan 51, and is connected to the cooling pipe 5 through a hose 53, and the hose 53 is long enough. With such a configuration, the variable frequency fan is provided with low-range, medium-range and high-range power, corresponding to low-speed wind, medium-speed wind and high-speed wind, that is, to achieve three-speed temperature regulation, and then cooperate with the up and down movement of the cooling pipe, so as to achieve a further cooling and temperature regulation effect of the PCB board. As shown Figure 5As shown: the cooling pipe 5 is also provided with a plurality of evenly distributed air holes 52, and the air holes 52 distributed on the two cooling pipes 5 are both oriented toward the PCB substrate workpiece distributed in the middle; in this arrangement, the staff turns on the fan, and the fan starts to deliver cold air into the cooling pipe, and then completes the air supply cooling operation of the PCB substrate workpiece through the air holes.

[0027] like Figure 3 As shown: In this embodiment, the second moving member 4 is used to drive the cooling pipe 5 to move forward and backward, and keep the upper cooling pipe 5 and the lower cooling pipe 5 moving in opposite directions. In a preferred embodiment, the second moving member 4 includes a fixed block 41, a second screw rod 42, a second guide rod 43 and a second motor 44. There are two fixed blocks 41, which are respectively arranged at the two ends of the cooling pipe 5; a carrier for the cooling pipe. Side wing plates 45 are provided on both sides of the front and rear of the connecting plate 34, and the two can be connected and fixed by welding. The second screw rod 42 is arranged between the side wing plates 45 on the left side and the front and rear distribution, and penetrates the fixed block 41 on the left side, and the second screw rod 42 is threadedly connected with the corresponding fixed block 41; such arrangement forms a screw nut structure, and the second guide rod 43 is arranged between the side wing plates 45 on the right side and the front and rear distribution, and penetrates the fixed block 41 on the right side, and the second guide rod 43 is slidably connected with the corresponding fixed block 41; such arrangement plays a good guiding role. The second motor 44 is arranged on one side of the side wing plate 45 through a bracket, and is connected to the second screw rod 42. The thread rotation directions of the second screw rod 42 above and the second screw rod 42 below are opposite. In the initial state, the two cooling tubes 5 are respectively located at the front and rear sides of the inner cavity of the box body 1. With such a configuration, when the staff starts the second motor, the second motor will drive the second screw rod to rotate synchronously. Due to the threaded connection between the second screw rod and the left fixed block, and the guiding sliding effect of the right fixed block and the second guide rod, the second screw rod will drive the fixed block and the cooling tube to move forward and backward as a whole. For a specific analysis of the example, when the second motor starts to rotate forward, it will drive the second screw rod to rotate clockwise, that is, the second screw rod distributed above will drive the fixed block and the cooling tube to move backward as a whole. The second screw rod distributed below will drive the fixed block and the cooling tube to move forward as a whole.

[0028] The cooperation of the fixed block, the second screw rod, the second guide rod and the second motor can drive the air supply pipe to move forward and backward, thereby ensuring the uniformity of air supply to the PCB board, and then utilizing the mobile and convenient air supply cooling to greatly improve the uniformity and quality of PCB board cooling. In this way, the cooling device can intelligently adjust the air supply volume to achieve the effect of conveniently adjusting the cooling temperature, and is more practical.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
