Description

Burning tool for PCBA

Technical Field

The utility model belongs to the technical field of burn record frock, concretely relates to burn record frock for PCBA.

Background

The circuit board is subjected to SMT loading and then subjected to the whole manufacturing process of a DIP plug-in, namely PCBA represents the circuit board with welded components. In the production process of the PCBA, burning of programs is often involved. In the prior art, the burning tool can only burn a chip or a circuit board with pins, but cannot burn a PCBA with only a bonding pad but no pins. In the prior art, the probe is directly led out from the burner to burn on the PCBA board, so that the operation is troublesome, the efficiency is low, and the condition of misoperation is easy to occur; or the burning is carried out by a needle bed, but the positioning of the needle bed is not accurate enough, the occupied area is large, the volume is too large, the carrying is inconvenient when people go out, and the structure is easy to damage.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a burn record frock for PCBA to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a burning tool for a PCBA comprises a burner and a burning connector arranged on the side wall of the burner. The top of the burner is provided with an upper cover plate and a lower bottom plate which are of cuboid structures with the same shape; the four top corners of the upper cover plate are provided with upper cover plate magnets, the four bottom corners of the lower base plate are provided with lower base plate magnets, and the upper cover plate magnets and the lower base plate magnets are identical in position and opposite in polarity and are used for attracting the upper cover plate and the lower base plate together; a burning interface is arranged on the side surface of the lower bottom plate and matched with the burning connector; the top surface of the lower bottom plate is provided with a placing groove for placing PCBAs to be burned; the bottom of the placing groove is provided with at least one round hole, and a single-head probe is arranged in the round hole and is used for being connected with a welding pad of the PCBA to be burned; the tail part of the single-head probe is electrically connected with the burning interface.

Furthermore, a positioning groove is formed in the bottom surface of the upper cover plate; the positioning groove and the placing groove are the same in shape, size and position. The positioning groove can further limit the PCBA to be burned, so that the askew PCBA to be burned can be automatically calibrated and reset.

Furthermore, the top surface of the upper cover plate is provided with a handle, so that the upper cover plate can be conveniently taken.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a through the upper cover plate and the lower plate of special design, realized the automatic alignment actuation for the probe can in close contact with PCBA's pad, is convenient for burn the record. The whole burning process is convenient and accurate in positioning and convenient to operate. The tool is small in size and convenient to carry.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Referring to the attached drawing 1 of the specification, the utility model relates to a burn record frock for PCBA, including burn record ware 4 and set up in burn record joint 5 of the lateral wall of burn record ware 4. The top of the burner 4 is provided with an upper cover plate 2 and a lower base plate 3, and the upper cover plate 2 and the lower base plate 3 are of cuboid structures with the same shape; the four top corners of the upper cover plate 2 are provided with upper cover plate magnets 1, the four bottom corners of the lower base plate 3 are provided with lower base plate magnets 7, and the upper cover plate magnets 1 and the lower base plate magnets 7 are identical in position and opposite in polarity and are used for attracting the upper cover plate 2 and the lower base plate 3 together; a burning interface 6 is arranged on the side surface of the lower bottom plate 3, and the burning interface 6 is matched with the burning connector 5; the top surface of lower plate 3 is equipped with places recess 8 for place the PCBA who waits to burn.

Referring to the attached drawing 2 of the specification, at least one round hole 9 is formed at the bottom of the placing groove 8, and the position of the round hole 9 is matched with the position of a pad of the PCBA to be burned. Preferably, but not by way of limitation, the circular holes 9 provided in this embodiment are twenty circular holes 9 arranged in a row, and are used for burning PCBA of a corresponding model.
