Description

Technical Field

[0001] The invention relates to a device for testing equipment of printed circuit boards, in particular to a handheld probe seat device. Background Art

[0002] See also Figure 1 and Figure 2 A conventional probe station 1 comprises a track set 11 and a probe frame 12. The track set 11 comprises two parallel Y-axis iron plates 111 and an X-axis iron plate 112 which is perpendicular to the Y-axis iron plate 111 and connected to the Y-axis iron plate 111 at both ends. The probe frame 12 is provided with a probe set 13 and is movably arranged on the track set 11, and the probe set 13 is used to measure a circuit board 9.

[0003] During measurement, the probe holder 12 needs to be moved on the Y-axis iron plate 111 and the X-axis iron plate 112 to the measuring position of the circuit board 9, and then the probe holder 12 needs to be adjusted so that the probe group 13 is lowered to contact the circuit board 9 for measurement. However, when measuring each measuring position of the circuit board 9, it is necessary to move and adjust the position of the probe holder 12 or the X-axis iron plate 112 each time, and make the probe group 13 contact the circuit board 9 before performing electrical measurement, which is inconvenient and time-consuming to operate. In addition, if the probe group 13 is forgotten to be withdrawn from the circuit board 9 after the measurement is completed, and the probe group 13 is directly moved to the next measuring position, the probe group 13 will collide with the parts on the circuit board 9 and be damaged, or the circuit board 9 will be scratched, and the damage rate is high, which needs to be improved.

[0039] Before the present invention is described in detail, it should be noted that in the following description, similar components are represented by the same reference numerals, and the front-to-back direction X, left-right direction Y, and up-down direction Z referred to in the following description are based on the user's operation. Figure 4 The front-rear direction X, the left-right direction Y and the up-down direction Z are substantially perpendicular to each other.

[0040] See also Figure 3 , Figure 4 and Figure 5The first embodiment of the handheld probe holder device of the present invention is suitable for being provided with two electrical measurement probes 7 and being placed on a surface 81 of a printed circuit board 8 and performing electrical measurement. The handheld probe holder device comprises a handheld holder 2, a lever unit 3, and a probe holder 4. In other examples, the handheld probe holder device can also be placed on other surfaces, such as the surface of a table.

[0041] The hand-held seat 2 includes a seat body 21 extending forward and backward, two hand-held pieces 22 respectively arranged on the left and right sides of the seat body 21 for holding, and two anti-slip sheets 23 arranged on the seat body 21. The seat body 21 has a bottom surface 211. Preferably, each hand-held piece 22 is a plate, and more preferably, each hand-held piece 22 has a plurality of grooves 221, the grooves 221 are formed on the outside and extend forward and backward and are spaced up and down, and a plurality of convex ribs 222 are formed between the grooves 221, and the convex ribs 222 are used to increase the friction when holding. The anti-slip sheet 23 is adhered to the bottom surface 211 of the seat body 21 and is used to prevent the seat body 21 from sliding arbitrarily, and in the first embodiment, the number of the anti-slip sheets 23 is two, and they are arranged adjacent to each other front and back, but in other variations, the number of the anti-slip sheets 23 can also be one, or more than three.

[0042] See also Figure 5 and Figure 6 Specifically, the seat body 21 has a support portion 212 and a stop portion 213 disposed in opposite directions along the front-rear direction X, two side seat portions 214 spaced apart from each other and connecting the support portion 212 and the stop portion 213, and two protective arm portions 215 extending forward from the support portion 212 and spaced apart from each other in the left-right direction Y. The side seat portions 214 are respectively provided for the handpieces 22 to be disposed, and the support portion 212, the stop portion 213 and the side seat portions 214 jointly define an opening 216 that passes through the handpieces 22 from top to bottom. A measuring port 217 that passes through the handpieces 22 from top to bottom is formed between the protective arm portions 215.

[0043] See also Figure 3 , Figure 5 and Figure 6The lever unit 3 is located between the hand-held parts 22 of the hand-held seat 2 and is rotatably pivoted to the hand-held seat 2. The lever unit 3 includes a movable part 31 pivoted to the hand-held seat 2, two bearings 32, and a pivot shaft 33. The movable part 31 has a plate 311 and a non-slip sheet 312 arranged on the bottom side of the plate 311. The plate 311 is generally stepped and has a fulcrum 313 pivoted to the hand-held seat 2 and passing through the opening 216, a front end 314 located before the fulcrum 313, a rear end 315 located after the fulcrum 313, and a connecting part 316 located between the front end 314 and the rear end 315. The distance between the fulcrum 313 and the front end 314 is smaller than the distance between the fulcrum 313 and the rear end 315, so that the rear end 315 has the potential energy to move downward constantly. The anti-slip sheet 312 is disposed on the bottom side of the connecting portion 316 and has a contact surface 317 located on the bottom side. The bearing 32 is rotatably disposed on the left and right sides of the movable member 31 and is located at the fulcrum 313 of the movable member 31. The pivot shaft 33 passes through the seat body 21 of the hand-held seat 2, the movable member 31, and the bearing 32 along the left-right direction Y. In this way, the movable member 31 can rotate around the fulcrum 313.

[0044] See also Figure 3 , Figure 4 and Figure 5 , the probe holder 4 is arranged on the movable part 31 and can rotate with the movable part 31, and the probe holder 4 includes a probe frame 41, a longitudinal fine-tuning button 42, and an angle fine-tuning button 43. The probe frame 41 faces forward and is located above the abutment portion 212 of the movable part 31. The probe frame 41 has a rotating head 411 that can be rotatably arranged on the front side clockwise or counterclockwise and is provided for the electrical measurement probe 7. In this way, the front end of the electrical measurement probe 7 is extended into the measurement port 217. In the first embodiment, the electrical measurement probe 7 is a differential pressure probe, so the number of the electrical measurement probes 7 is two, but in other variations, the electrical measurement probe 7 can also be a single-ended probe, so the number of the electrical measurement probe 7 can also be only one, and the rotating head 411 of the probe frame 41 can also be provided for only one electrical measurement probe 7. The longitudinal fine-tuning button 42 is used to drive the probe frame 41 to move linearly up and down. The angle fine-tuning knob 43 is used to drive the rotating head 411 to rotate clockwise or counterclockwise around its own axis, thereby achieving the function of fine-tuning the electrical property measurement probe 7 after reaching a predetermined position.

[0045] In addition, the electrical measurement probe 7 of the first embodiment is located between the protective arms 215 , which can prevent the electrical measurement probe 7 from being hit when the handheld probe holder device is moved.

[0046] See also Figure 5 and Figure 7 The handheld probe holder device can be in a holding state (such as Figure 7 ) and a measurement state (such as Figure 5 ). In the picking state, due to the effect of gravity, the movable member 31 rotates in a direction in which the rear end portion 315 faces downward and the front end portion 314 faces upward, and drives the probe seat 4 to rotate in a direction in which the front side faces upward and the rear side faces downward, and the abutting surface 317 of the movable member 31 partially exposes the bottom surface 211 of the seat body 21 from the opening 216. At this time, the electrical measurement probe 7 moves in a direction away from the bottom surface 211 of the seat body 21. Figure 5 As shown, when the handheld probe holder device is placed on the surface 81 of the printed circuit board 8 and switched to the measuring state, the abutting surface 317 of the movable member 31 abuts against the surface 81 and pushes the movable member 31 to rotate in a direction with the rear end 315 facing upward and the front end 314 facing downward, so that the probe holder 4 rotates in a direction with the front side facing downward and the rear side facing upward, so that the electrical measurement probe 7 contacts the printed circuit board 8 downward.

[0047] When performing electrical measurement, first hold the handpiece 22 of the handheld holder 2, then pick up the handheld holder 2, move it to the position above the printed circuit board 8 where the measurement is required, and then place it on the surface 81 of the printed circuit board 8 to switch the handheld probe holder device to the measurement state, so that the electrical measurement probe 7 contacts the surface 81 of the printed circuit board 8 to perform electrical measurement. When there is a gap between the electrical measurement probe 7 and the surface 81 of the printed circuit board 8 but they are not in contact, the longitudinal fine-tuning knob 42 and the angle fine-tuning knob 43 of the probe holder 4 can be adjusted so that the electrical measurement probe 7 contacts the surface 81 of the printed circuit board 8 to perform electrical measurement. It should be noted that, regardless of whether the number of the electrical measurement probes 7 is one or two, as long as the longitudinal fine-tuning knob 42 and the angle fine-tuning knob 43 are adjusted for the first time to make the electrical measurement probes 7 contact the printed circuit board 8, when moving to the next measurement state, there is no need to adjust the longitudinal and horizontal positions of the electrical measurement probes 7. When it is necessary to perform multi-point measurement on the printed circuit board 8 or to measure a large number of mass-produced printed circuit boards 8, the operation is more convenient and time-saving.

[0048] See also Figure 7 and Figure 8In the first embodiment, the movable member 31 of the lever unit 3 further has a front bolt 318 and a rear bolt 319. The front bolt 318 is inserted into the front end portion 314 so as to be movable up and down, and is used to abut against the abutting portion 212 of the seat body 21 to adjust the forward tilt angle. The rear bolt 319 is inserted into the rear end portion 315 so as to be movable up and down, and is used to abut against the limiting portion 213 of the seat body 21 to adjust the backward tilt angle. By blocking the movable member 31 with the rear bolt 319, the electrical measurement probe 7 can be prevented from being damaged due to excessive backward tilting and being separated from the measurement port 217. In other variations, the front bolt 318 and the rear bolt 319 can be omitted, and excessive backward tilting can also be prevented by providing a stopper (not shown) on the probe seat 4 and using the handpiece 22 to stop the stopper.

[0049] In the first embodiment, the anti-slip sheet 23 of the hand-held seat 2 and the anti-slip sheet 312 of the movable part 31 are silicone sheets containing conductive powder, and the conductive powder is carbon powder. The anti-slip sheet 23 and the anti-slip sheet 312 are used to increase the friction between the hand-held probe seat device and the surface 81 when in the measuring state, so as to avoid the electrical measurement probe 7 from moving on the surface 81 of the printed circuit board 8 in a forward and backward or left and right sliding manner, thereby avoiding damage to the electrical measurement probe 7, scratching of the printed circuit board 8 or electrostatic damage. However, in other variations, the anti-slip sheet 23 and the anti-slip sheet 312 can also be omitted. As long as a silicone sheet of the above material is used during measurement, it is first placed on the surface 81 of the printed circuit board 8 and placed for the hand-held probe seat device to achieve the same anti-slip effect.

[0050] The present invention can be directly moved by hand through the hand-held part 22 of the hand-held seat 2, which is easy to operate. In addition, the distance between the fulcrum 313 and the front end 314 of the movable part 31 of the lever unit 3 is smaller than the distance between the fulcrum 313 and the rear end 315, so that when the hand-held probe seat device is in the picking state, the abutting surface 317 of the movable part 31 partially exposes the bottom surface 211 of the seat body 21 from the opening 216, and the probe seat 4 rotates in the direction of the front side facing upward and the rear side facing downward to drive the electrical measurement probe 7 to leave the surface 81 of the printed circuit board 8, which can avoid scratching the printed circuit board 8 or crashing the electrical measurement probe 7. The present invention also has the effect of reducing the damage rate. In this way, the purpose of the present invention can be achieved.

[0051] See also Fig. 9 , Fig.10 and Fig.11 The second embodiment of the handheld probe holder device of the present invention is substantially the same as the first embodiment, except that:

[0052] The handheld probe seat device further comprises a placement seat 5, and the placement seat 5 is used to place the handheld seat 2. The placement seat 5 comprises a bottom plate 51 extending along the front-to-back direction X and on which the handheld seat 2 is placed, a baffle plate 52 arranged at the front side of the bottom plate 51 and extending upward, and a positioning group 53 arranged at the rear side of the bottom plate 51 and used to limit the handheld seat 2 from escaping.

[0053] The bottom plate 51 has a recessed groove 511 at the front side and a notch 512 formed at the rear side. The recessed groove 511 is suitable for accommodating the electrical measurement probe 7 to prevent the electrical measurement probe 7 from hitting the bottom plate 51. The baffle 52 is used to block the protective arm 215 of the hand-held seat 2. The positioning group 53 is located in the notch 512 and has a buckling member 531, an adjusting member 532, and two elastic members 533. The buckling member 531 is movably disposed in the notch 512 of the bottom plate 51, and the buckling member 531 has a buckling portion 534 for buckling against the seat body 21 of the hand-held seat 2. The adjusting member 532 is screwed to the buckling member 531 and the bottom plate 51 so as to be movably disposed in the notch 512 of the bottom plate 51, and the buckling member 531 has a buckling portion 534 for buckling against the seat body 21 of the hand-held seat 2. The adjusting member 532 is screwed to the buckling member 531 and the bottom plate 51 so as to be movably disposed in the notch 512 of the bottom plate 51, and is used to drive the buckling member 531 to move forward and backward. The elastic member 533 is elastically pressed between the bottom plate 51 and the buckling member 531 and provides an elastic restoring force. In the second embodiment, the number of the elastic members 533 is two, but in other variations, the number of the elastic members 533 may be one or more than three.

[0054] The placement seat 5 can be used to place the handheld seat 2. When the handheld probe seat device needs to be transported, the handheld seat 2 can be placed on the placement seat 5, and the buckling member 531 can be buckled against the seat body 21 of the handheld seat 2 to prevent the handheld seat 2 from being damaged by arbitrary movement during transfer or transportation between work stations.

[0055] Thus, in addition to having the same purpose and function as the first embodiment, the second embodiment also has a better storage method and better transportation stability.

[0056] See also Fig.12 , Fig.13 and Fig.14 The third embodiment of the handheld probe holder device of the present invention is substantially the same as the second embodiment, except that:

[0057] The buckling member 531' of the positioning group 53' further comprises two first positioning portions 535 formed at the rear side and arranged at intervals, and a notch 536 formed at the rear side and penetrating vertically and located between the first positioning portions 535. The positioning group 53' eliminates the adjusting member 532, and the positioning group 53' further comprises a connecting rod 537 and a positioning member 538. The connecting rod 537 is inserted through the buckling member 531' and the bottom plate 51 of the placement seat 5. The positioning member 538 is pivotally connected to the rear end of the connecting rod 537 and is located in the notch 536 of the buckling member 531'. The positioning member 538 comprises a pivoting portion 539 pivotally connected to the connecting rod 537 and having a circular arc at the bottom end, a swinging portion 540 extending upward from the pivoting portion 539, and a positioning rod 541 inserted through the swinging portion 540 along the front-rear direction X. The positioning rod 541 has a second positioning portion 542 located at the front end and used for being engaged with any one of the first positioning portions 535 of the buckling member 531 ′.

[0058] In the third embodiment, each first positioning portion 535 of the buckling member 531' is a concave hole, and the second positioning portion 542 of the positioning member 538 is a flange, but in other variations, each first positioning portion 535 and the second positioning portion 542 may be a flange and a concave hole, respectively. In addition, the second positioning portion 542 is located at the front end of the positioning rod 541, but in other variations, the second positioning portion 542 may also be directly formed at the front side of the swinging portion 540 of the positioning member 538, that is, the positioning rod 541 may be omitted.

[0059] In the third embodiment, the number of the first positioning portions 535 of the buckling member 531 ′ is two, but in other variations, the number of the first positioning portion 535 may be only one.

[0060] See also Figures 15 to 19 When the hand-held seat 2 needs to be positioned, the buckling member 531' can be pushed forward and buckled against the seat body 21 of the hand-held seat 2, and then the positioning member 538 is rotated to make the second positioning portion 542 snap into any one of the first positioning portions 535 of the buckling member 531', so that the hand-held seat 2 can be positioned. When the hand-held seat 2 needs to be taken away, the positioning member 538 is rotated again to make the second positioning portion 542 disengage from any one of the first positioning portions 535, and the elastic restoring force of the elastic member 533 will push the buckling member 531' backward, so that the buckling member 531' is away from the hand-held seat 2, and the hand-held seat 2 can be taken away.

[0061] Compared with the second embodiment, a hand tool (not shown) is required to rotate the adjustment member 532 (such as Fig.11) and then drive the buckling member 531 to move and position the hand-held seat 2. In the third embodiment, the hand-held seat 2 can be positioned by simply pushing the buckling member 531' and rotating the positioning member 538 so that the second positioning portion 542 is engaged with any of the first positioning portions 535, and the positioning is relatively quick. In this way, in addition to having the same purpose and function as the second embodiment, the third embodiment also has better convenience of use.

[0062] The above are merely embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention still fall within the scope of the present invention.
