[0005] Nowadays in the automated production operation, the mechanical hand is used for loading or unloading to cooperate with the burning station, which can greatly improve the production efficiency, that is, the mechanical hand is used for grabbing the circuit board and placing it on the burning station or grabbing the burned circuit board from the burning station and placing it on the conveying line. However, in the above-mentioned existing burning equipment technical scheme, in order to ensure the stability of the product during the burning process, the upper part of the product is usually provided with a pressing structure, and the driving member is used to drive the pressing structure to displace upward and downward to press the product on the burning station. After the product is burned, although the pressing structure is separated from the product, it is still in the upper area of the product.

Therefore, the existing burning equipment is not convenient for arranging the mechanical hand for loading and unloading, and needs to be improved. SUMMARY

[0015] The utility model will be further described in detail below in combination with the accompanying drawings and related contents: Figures 1-6

[0016] A circuit board burning tool, including flatly the platform 10, be provided with the placement area of bearing circuit board A on the platform 10 and the placement area is equipped with the burning probe 20 for abutting circuit board A bottom burning contact point, the placement area of circuit board A is provided with the compression unit 30 above, drive unit 40 drives the compression unit 30 and shifts to the compression unit 30 and the limit position of the compression unit 30 and the board surface of circuit board A and drives the compression unit 30 and shifts to the avoidance position of the compression unit 30 and the board surface of circuit board A and the region above the board surface of circuit board A is misaligned.

[0017] In the above scheme, during the program burning process of the circuit board A, the drive unit 40 can drive the compression unit 30 to shift to the avoidance position misaligned with the region above the board surface of the circuit board A on the platform 10, so that the region above the board surface of the circuit board A is not blocked, and the mechanical hand can move to the region above the board surface of the circuit board A to grasp the circuit board A and unload the circuit board A from the placement area on the platform 10. Since the compression unit 30 is misaligned with the region above the board surface of the circuit board A on the platform 10, the compression unit 30 will not interfere with the movement of the mechanical hand. By this arrangement, it is convenient to arrange the mechanical hand to load or unload the circuit board A on the placement area of the circuit board A on the platform 10, which also helps to simplify the movement path of the mechanical hand and improve the overall operation efficiency of the equipment.

[0018] It should be noted that in the prior art, the circuit board A needs to be placed on the platform 10 during the burning process, and the circuit board A is generally small and thin in size. The mechanical hand usually grasps the circuit board A by adsorbing the board surface of the circuit board A with a suction cup. Therefore, if the compression unit 30 is always kept above the region above the board surface of the circuit board A, it is necessary to consider whether the mechanical hand components located above the board surface of the circuit board A will interfere with the compression unit 30.

[0019] ​As a preferred solution, the lower end of the carrier 10 is provided with a stand 50, the stand 50 is provided with a first telescopic cylinder 41, the rod core of the piston rod of the first telescopic cylinder 41 is located in the plumb direction and the rod end is connected with a mounting plate 42, the mounting plate 42 is provided with a rotary cylinder 43, the shaft core of the rotary shaft of the rotary cylinder 43 is located in the plumb direction and the shaft end is connected with the pressing unit 30. In this solution, the first telescopic cylinder 41 can drive the mounting plate 42 to move up and down together with the rotary cylinder 43 thereon, so as to make the pressing unit 30 connected with the shaft end of the rotary cylinder 43 move up and down, thereby pressing the circuit board A placed on the carrier 10; and the rotary cylinder 43 can drive the pressing unit 30 to rotate around the rotary shaft of the rotary cylinder 43 as the rotation core, so as to make the pressing unit 30 be positioned to the avoidance position arranged in the region above the board surface of the circuit board A, so as to make the mechanical hand grab the circuit board A burned or place the circuit board A to be burned on the carrier 10.

[0020] Further, the rotary shaft of the rotary cylinder 43 is connected with a connecting arm 44 suspended in the radial direction, and the pressing unit 30 is connected to the suspended end of the connecting arm 44. The connecting arm 44 serves as a transition connecting piece between the pressing unit 30 and the rotary cylinder 43, which ensures that the cylinder body of the rotary cylinder 43 is reasonably avoided from the circuit board A, and at the same time enables the pressing unit 30 to press the circuit board A.

[0021] As a preferred solution, the stand 50 is provided with a second telescopic cylinder 60, the rod core of the piston rod of the second telescopic cylinder 60 is located in the plumb direction and the rod end is connected with a probe seat 61, the burning probe 20 is arranged on the probe seat 61, and the pressing unit 30 is in the limiting position pressing the circuit board A on the board surface. The second telescopic cylinder 60 drives the probe seat 61 to move up to the burning position where the burning probe 20 abuts against the bottom burning contact of the circuit board A or drives the probe seat 61 to move down to the initial position where the burning probe 20 is separated from the bottom burning contact of the circuit board A.

[0022] In this solution, the second telescopic cylinder 60 drives the probe seat 61 to move up and down, thereby controlling whether the burning probe 20 contacts the bottom burning contact of the circuit board A on the carrier 10. In the case that the pressing unit 30 presses the circuit board A on the board surface, the second telescopic cylinder 60 drives the probe seat 61 to move up, so that the burning probe 20 thereon abuts against the burning contact on the circuit board A to perform program burning, and the burning probe 20 maintains good contact with the circuit board A, thereby avoiding the situation that the burning probe 20 and the circuit board A are not in good contact, which leads to burning failure.

[0023] Further, in combination with Figure 3 and Figure 5As shown, since the circuit board A needs to be placed on the carrier 10, the burning probe 20 is located below it. In order to avoid the interference between the probe base 61 or the burning probe 20 and the carrier 10, a slot 11 is arranged in the middle of the carrier 10, and the probe base 61 is located in the slot 11. Through the arrangement of the slot 11, the probe base 61 or the burning probe 20 and the carrier 10 are mutually avoided.

[0024] As a preferred solution, in combination with Figure 1 , Figure 2 and Figure 4 As shown, the stand includes a column 51 connected to the lower end face of the carrier 10, and the lower end of the column 51 is connected to a base 52, and the first and second mounting frames 53A and 53B are arranged on the base 52, and the first and second telescopic cylinders 41 and 60 are respectively mounted on the first and second mounting frames 53A and 53B. The first and second telescopic cylinders 41 and 60 are both located below the carrier 10, and at the same time, the first telescopic cylinder 41 is connected to the rotary cylinder 43 from bottom to top, optimizing the space above the carrier 10, and effectively avoiding the interference of the mechanical hand when it is transposed above each burning tool.
