DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-3 The utility model provides a technical solution: an efficient circuit program burning device, comprising a clamping mechanism 2, a matching mechanism 3 movably connected to the clamping mechanism 2, and a probe mechanism 4 movably connected to the matching mechanism 3;

[0027] The clamping mechanism 2 includes a fixing assembly 23, a connecting member 22 and a handle assembly 21. The handle assembly 21 is divided into a handle portion 211 and a connecting portion 212. The handle assembly 21 and the fixing assembly 23 are hingedly connected through the connecting member 22 and the matching mechanism 3.

[0028] The probe mechanism 4 includes a probe assembly 41, the lower end of the probe assembly 41 is fixedly connected to a spring ejector pin 42, and the upper end of the probe assembly 41 is plugged into a wiring socket 43;

[0029] The handle portion 211 is pressed down, and cooperates with the connecting piece 22 and the matching mechanism 3 in a hinged manner to drive the probe mechanism 4 to move downward. The end of the spring ejector pin 42 in the probe mechanism 4 corresponds to the burning point of the circuit board and is in stable contact.

[0030] During the burning operation, the burning point of the circuit board can be accurately located; after the handle portion 211 of the clamping mechanism 2 is pressed down, the matching mechanism 3 is locked according to the action of gravity, so that the spring ejector 42 of the probe mechanism 4 is in stable contact at the burning point, which can solve the problem of poor matching between the burner and the circuit board to be burned, and achieve the effect of stable burning and high burning efficiency.

[0031] In this embodiment, the matching mechanism 3 includes a sliding frame 31, and an upper sliding block 32 and a lower sliding block 33 are respectively provided at the upper and lower ends of the sliding frame 31. The sliding frame 31, the upper sliding block 32, the lower sliding block 33 and the probe assembly 41 are fixed using bolts.

[0032] In this embodiment, the upper sliding block 32 and the lower sliding block 33 can slide forward and backward along the direction of the handle portion 211 .

[0033] When the front and rear positions of burning need to be changed, the upper sliding block 32 and the lower sliding block 33 are moved along the direction of the handle portion 211. The positions of the upper sliding block 32 and the lower sliding block 33 correspond to each other. After adjustment, they are fixed with bolts. Different contact pressures can be applied to the circuit board, or used in conjunction with different circuit boards.

[0034] In this embodiment, a sliding groove 411 perpendicular to the direction of the handle portion 211 is provided at the rear end of the probe assembly 41 , and the matching mechanism 3 can slide in the sliding groove 411 .

[0035] When the left and right positions of the burning need to be changed, the probe mechanism 4 can be moved in the sliding slot 411 and fixed with bolts after adjustment, so as to match different burning point positions of different circuit boards.

[0036] In this embodiment, a bottom plate 1 is fixedly connected to the lower surface of the fixing assembly 23 , and a fixing column 12 is arranged on the upper surface of the bottom plate 1 .

[0037] When the circuit board is placed on the bottom plate 1, the fixing posts 12 correspond to the openings at the four corners of the circuit board, making the placement convenient and accurate.

[0038] In this embodiment, a foot seat 11 is disposed on the lower surface of the base plate 1 .

[0039] Four feet 11 can be provided, which are fixed on the four corners of the lower surface of the base plate 1 respectively, so that the base plate 1 is kept in a horizontal direction without shaking, thereby stabilizing the burning process.

[0040] In this embodiment, the fixing column 12 is movably connected to the upper surface of the base plate 1 .

[0041] The fixing column 12 can be plugged into the base plate 1. The fixing column 12 can also be a bolt. There are matching threaded holes on the base plate 1. When burning different circuit boards, the position of the fixing column 12 can be changed so that the fixing column 12 corresponds to the opening of the new circuit board.

[0042] In this embodiment, four fixing posts 12 are provided, corresponding to the openings of the circuit board respectively.

[0043] In this embodiment, the fixing assembly 23 includes a fixing block 231 and a fixing frame 232 , and the fixing block 231 and the fixing frame 232 are connected by bolts.

[0044] The function of the clamping mechanism 2 is achieved through an articulated connection. Specifically, the handle portion 211, the connecting piece 22, the fixing frame 232 and the end of the sliding frame 31 close to the handle portion 211 are each provided with two pairs of corresponding openings, and the openings are hinged in sequence. When the handle portion 211 is pressed down, the four groups of hinges are linked to make the two groups of openings of the sliding frame 31 close to the end of the handle portion 211 in the vertical and horizontal directions. Since the matching mechanism 3 and the probe mechanism 4 are fastened and do not slide during burning, the spring ejector pin 42 is perpendicular to the circuit board at this time, thereby realizing the clamping effect of the clamping mechanism 2.

[0045] In this embodiment, the portion of the cable socket 43 away from the probe assembly 41 is the data cable.

[0046] It is connected to an external PC or program storage via a data cable to achieve power supply or program burning.

[0047] When using:

[0048] Put the burning device on a horizontal table to ensure that the device is placed stably without shaking, put the circuit board on the bottom plate 1, the opening on the circuit board corresponds to the fixing column 12, keep the circuit board stable and not shaking, insert the cable socket 43 into the probe assembly 4, and then adjust the upper sliding block 32 and the lower sliding block 33, adjust the front and rear position of the probe assembly 41, and then adjust the left and right position of the probe assembly 41. After the position is determined, use bolts to fix the matching mechanism 3 and the probe assembly 41, press the handle part 211 downward, the handle part 211 is hinged and linked, and drives the sliding frame 31 to move downward, thereby driving the spring ejector pin 42 of the probe mechanism 4 to move downward, corresponding to the burning point of the circuit board and stably contacting, and then carry out the burning work; after the burning is completed, lift the handle part 211 to drive the spring ejector pin 42 to move upward, at this time the handle part 211 and the upper surface of the sliding frame 31 form a "V" shape, pull out the cable socket 43, and remove the circuit board.
