Description
Technical field
The present invention relates to a kind of global function jigsaw to test Pneumatic fixture.
Background technique
Currently, a kind of most popular technology and technique are surface mounting technologies in electronic assembly industry, English name is
SMT, SMT are a kind of surfaces on surface or other substrates that no pin or short leg surface-assembled component are mounted on to pcb board
On, the circuit load technology of welding assembly is subject to by the methods of Reflow Soldering or immersed solder.If assembling component, there are rosin joints, company
There are colloid substances, and pcb board can all be caused the bad shape of service interruption occur on the key of the problems such as tin or pcb board route
Condition, therefore need to detect the pcb board for having carried out SMT before factory, and the product big now for amount, Ke Husuo
It is lower to price, therefore how save the cost is SMT factory director's phase problem in need of consideration, but for measuring big product, carry out
Detection after SMT is all usually test fixture using hand, and can only singly put into inside test fixture into
Row test, not only speed is slow, high labor cost, while there is also security risk, test fixture is easy hand folding.As can designing
The global function jigsaw that a kind of testing efficiency is high and security performance is high tests Pneumatic fixture, then can be well solved the above problem.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a kind of testing efficiency it is high and
The high global function jigsaw of security performance tests Pneumatic fixture.
The technical scheme adopted by the invention is that: the present invention includes pedestal, needle plate, support plate and pressing plate, and the support plate is placed
On the base, the top of the support plate is arranged in the needle plate, and the top of the needle plate, the bottom is arranged in the pressing plate
The both ends of seat are provided with key, cylinder are provided on the pressing plate, two keys are connect with the air cylinder signal.
By above scheme as it can be seen that board under test is put on support plate, then only while by the key at lower bottom base both ends, cylinder
It can start and pressing plate is pushed to move downward, pressing plate presses together needle plate and support plate, on the probe and support plate on needle plate
Board under test test lead connection, whether and then it is qualified to be able to detect board under test.Because the key for starting cylinder is arranged in pedestal
Both ends the security performance of test is greatly increased, if one hand is pressed so being merely able to the hands remove to press the key at both ends
Lower key is just able to carry out pressing test, then operator is possible to when board under test is put into support plate, due to being eager to test
And press the button at once, being in this case easy for can there is a situation where clamp hands.In addition, being improved to gas by the mode manually pressed
The mode of cylinder pressing, speeds lower needle speed, improves work efficiency, reduce human cost, accelerate out ETCD estimated time of commencing discharging.
Further, several carriers are provided on the support plate, several described support plates are placed with board under test.Thus
As it can be seen that can further improve testing efficiency with the multiple boards under test of disposable test by being provided with multiple carriers, subtract
Human cost is lacked.
Further, there are three the carriers, three carriers to be placed with the board under test for setting on the support plate.
It can be seen that by setting, there are three carriers, can further improve test effect with three boards under test of disposable test
Rate reduces human cost.
Further, the pedestal setting is fluted, and the support plate is slidably matched with the groove, and the two of the pedestal
Side is provided with handle.It can be seen that support plate when placing board under test, directly uses hand by being slidably matched with the groove on pedestal
It draws and support plate is pulled out outside pedestal, then put board under test, then support plate is put on pedestal again and is matched with groove, makes to put to be measured
This process of plate is more convenient.In addition, pedestal two sides are additionally provided with handle, this also can be more easily moved in this way
Invention, meets the actual needs of operator.
Further, four positioning columns are provided on the pedestal, four positioning columns are each passed through the pressing plate
On the base with the Corner Strapped of the needle plate, four positioning columns are matched with the pressing plate and needle plate sliding
It closes.It can be seen that being slidably matched with pressing plate and needle plate by being provided with four positioning columns, during pressing plate pressing, no
Only needle plate knit stitch can be allowed more smooth, and probe can be allowed more accurately to align the test lead of board under test.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram that support plate stretches out pedestal.
Specific embodiment
As depicted in figs. 1 and 2, the board under test 8 is the pcb board for having carried out SMT in the present embodiment, and the present invention includes bottom
Seat 1, needle plate 2, support plate 3 and pressing plate 4, the pedestal 1 are arranged fluted 9, and the support plate 3 is slidably matched with the groove 9, when putting
When setting the board under test 8, directly the support plate 3 described in handle pulls out 1 outside of pedestal, then puts the board under test 8, then
The support plate 3 is put on the pedestal 1 again and is matched with the groove 9, makes to place this process of the board under test 8 more
Convenient and efficient, there are three the carriers 7, three carriers 7 to be placed with the board under test 8 for setting on the support plate 3, in this way
Can the multiple boards under test 8 of disposable test, improve testing efficiency, the upper of the support plate 3 is arranged in the needle plate 2
The top of the needle plate 2 is arranged in side, the pressing plate 4, and the both ends of the pedestal 1 are provided with key 5, set on the pressing plate 4
It is equipped with cylinder 6, two keys 5 are connect with 6 signal of cylinder, only press the described of 1 both ends of pedestal simultaneously
Key 5, the cylinder 6 can start and the pressing plate 4 pushed to move downward, and the pressing plate 4 is the needle plate 2 and the load
Plate 3 presses together, and the probe on the needle plate 2 is connect with the test lead of the board under test 8 on the support plate 3, Jin Erneng
Whether qualified enough detect the board under test 8.Because the both ends of the pedestal 1 are arranged in the key 5 for starting the cylinder 6,
So being merely able to the hands remove to press the key 5 at both ends, the security performance of test is greatly increased, if one hand is pressed
The key 5 is just able to carry out pressing test, then operator is possible to when the board under test 8 is put into the support plate 3,
The key 5 is pressed at once due to being eager to test, and being in this case easy for can there is a situation where clamp hands.Meanwhile by artificial
The mode of pressing is improved to the mode of cylinder pressing, speeds lower needle speed, improves work efficiency, reduces human cost,
Accelerate out ETCD estimated time of commencing discharging.Four positioning columns 11 are provided on the pedestal 1, four positioning columns 11 are each passed through the pressing plate
4 with the Corner Strapped of the needle plate 2 on the pedestal 1, four positioning columns 11 with the pressing plate 4 and the needle plate 2
It is slidably matched, in this way during the pressing plate 4 presses, 2 knit stitch of needle plate can not only be allowed more smooth, and can
Probe is allowed more accurately to align the test lead of the board under test 8.In addition, the two sides of the pedestal 1 are provided with handle 10, this
Sample can more easily move the present invention, meet the actual needs of operator.
The present invention is applied to pcb board testing field.
