The following describes in detail the universal tool for PCBA testing and programming, taking five sets of fixed rollers with guide grooves and five sets of components thereof as examples. Of course, the protection scope of the present invention is not limited to five sets of fixed rollers with guiding grooves and the form of the five sets of components thereof, the number of the fixed rollers with guiding grooves and the number of the components depend on the size of the horizontal Y axis direction of the PCBA board to be tested, i.e. the size between the first side (left side) and the second side (right side) of the PCBA board, so that the multi-component schemes except the five sets of fixed rollers with guiding grooves and the five sets of components thereof are also within the protection scope of the present invention.

Referring to fig. 1, there is shown a five-set fixed roller with guide grooves and a universal fixture for PCBA testing and programming of five-set components thereof, including a fixture base 100, a PCBA horizontal left limit device 200 (which is the aforementioned PCBA horizontal first side limit device), a PCBA horizontal upper limit device 300 (which is the aforementioned PCBA horizontal second side limit device), a PCBA size adapting device 400, and 5 components 500 of a PCBA appearance adapting device. Five components 500 are mounted on the PCBA size-conforming device 400 and move as the PCBA size-conforming device 400 is adjusted.

Referring to fig. 2, the structure of the PCBA horizontal left stop is shown. The PCBA horizontal left stop 200 is comprised of five fixed rollers 203 with guide grooves 204, rollers 202 and roller bases 201. Five fixed rollers 203 are linearly arranged in the horizontal direction of the roller base 201 through respective rollers 202; the guide grooves 204 of the five fixed rollers 203 vertically support the left side of the PCBA, can bear the pressure of pressing down of a probe during testing and programming, and meanwhile, the five fixed rollers 203 limit the PCBA to move left; the guide grooves 204 on the five fixed rollers 203 play a horizontal guide role when the PCBA board is horizontally inserted and extracted, and the five fixed rollers 203 roll around the rolling shaft 202 during insertion, so that friction can be reduced, and meanwhile, the PCBA is prevented from being damaged during the inserting and extracting processes.

Referring to fig. 3, the structure of the horizontal upper stop of the PCBA is shown. The PCBA horizontal upper stop device 300 comprises a baffle 301 with a groove 303 and a pair of sensors 302, the groove 303 on the baffle 301 limits the PCBA to move horizontally upwards and supports the horizontal upper end of the PCBA. A pair of sensors 302 are provided on the left and right sides of the bezel 310 for a pair of photoelectric sensors to detect whether the PCBA board is inserted in place, for triggering a detection or programming action.

Referring to fig. 4, the PCBA is shown in its configuration to size fit the device. The PCBA size adaptation device 400 is composed of two slide rails 401a and 401b, a substrate 402 mounted on the two slide rails 401a and 401b, and a positioning bolt 403. The position of the base plate 402 is adjusted on the two slide rails 401a and 401b, and the openings between the five components 500 and the PCBA horizontal left limiting device 200 in the PCBA profile adaptation device are adjusted as a whole, so as to adapt to PCBA boards of different sizes. After adjustment, the positioning bolt 403 is tightened to set. The same product only needs to be adjusted once during batch test and programming, and only needs to be adjusted again when the product to be tested is replaced.

Referring to fig. 5, the configuration of the PCBA form-adapting device is shown. The PCBA contour adaptation device consists of five identical components 500, wherein each component 500 consists of a sliding rail 501, a sliding block 502, a roller 506 with a guide groove 507, a rolling shaft 508, a sliding rod 503, a spring 504 and a sliding rod limiting guide seat 505. The slide rail 501 and the slide bar limit guide seat 505 in each assembly 500 are installed on the base plate 402, one end of the slide bar 503 is installed on the slide bar guide seat 505, and the other end of the slide bar 503 is inserted into the slide block 502 in a sliding manner. The sliding block 502 of each assembly 500 can freely extend and contract on the sliding rail 501 of the assembly 500, the spring 504 is sleeved on the sliding rod 503 and is positioned between the sliding block 501 and the sliding rod limit guide seat 505, the roller 506 with the guide groove 507 is arranged on the sliding block 502 through the roller 508, and the roller 506 rotates around the roller 507.

When the PCBA board is horizontally inserted, the guide grooves 507 of the rollers 506 play a role in insertion guide, and meanwhile, the guide grooves 507 can vertically support the PCBA board during detection. Because of the tension of the spring 504, the roller 506 always contacts the left side of the PCBA, and in the inserting process of the PCBA, the sliding block 502 changes along with the change of the outer edge of the right side of the PCBA and enables the PCBA to be always clamped in the guide groove of the roller 506, so that the appearance adapting function of the PCBA is realized.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
