The sealant 7 for including backplane level 6 and being fixed on backplane level 6, sealant 7 are sealedly and fixedly connected with backplane level 6, the side of sealant 7
Just change, when sealant 7 with easily wearing long, directly can replace the sealant 7 of abrasion is overall, float layer 4 and bottom plate
Layer 6 is fixedly connected, and sealant 7 is the sandwich of layers containing flexible layer, and sealant 7 is by 10 groups of metal level 8, rubber layer 9 and metal level
Into；The workpiece to be detected 12 of its support is placed on sealing mechanism 24 by support mechanism 22, and workpiece 12 to be detected tips upside down on sealer
On structure 24, a closed cavity is enclosed with sealing mechanism 24；Position-limit mechanism 21 be stuck on workpiece 12 to be detected limit it is to be checked
Workpiece 12 is surveyed to move up.Position-limit mechanism 21 shifts position onto and is tightly stuck in workpiece 12 to be detected after workpiece 12 to be detected falls in place
On sealing mechanism 24.
The diagonal angle of support mechanism 22, which is provided with detection sensor, ensures that workpiece 12 is in place, during ensureing that workpiece 12 declines
It is not in that inclination is blocked that level, which declines, and the diagonal angle of position-limit mechanism 21 also is provided with workpiece sensing sensor, and position-limit mechanism 21 moves
After in place, workpiece sensing sensor can be detected to the workpiece 12 below position-limit mechanism 21, it is ensured that bottom jacking cylinder 5 is pushed up
It is safe and punctual to be raised to position.
Wherein, support mechanism 22 has certain vertical drop with sealing mechanism 24, so as to avoid robot from grabbing
Hand directly contacts with sealant 7 and damages the structure of sealant 7；Support mechanism 22 includes locating part 13, cylinder 14 and supporting parts
15, supporting parts 15 are fixed on the output shaft of cylinder 14, and cylinder 14 drives supporting parts 15 to move up or down, and locating part 13 is solid
It is scheduled on base 1, and each vertical height of the locating part 13 of support mechanism 22 away from the plane of base 1 is consistent, locating part 13 can
The maximum height that limitation supporting parts 14 move up, the required highest for moving up the supporting parts 14 of each support mechanism 22 are high
Spend it is in the same plane so that four support mechanisms 22 are in the workpiece battery collet 12 to be detected that gets off from handgrip of undertaking
When, make battery collet 12 to be horizontal positioned, will not be with horizontal plane run-off the straight；Position-limit mechanism 21 includes being fixed on base 1
Guide rail 16, the moving member 17 slid back and forth along guide rail 16 and the actuating unit for driving moving member 17 to move forward and backward, moving member
17 are stuck on workpiece 12 to be detected, limit workpiece 12 to be detected and move up；Actuating unit include motor 18 and with motor 18
The ball screw 19 that output shaft is fixedly connected, ball screw 19 cooperates with the sliding sleeve 20 on moving member 17 and connected, with rolling
The rotation of ballscrew 19, the counter ball screw mandrel 19 of sliding sleeve 20 are moved forward or rearward, so as to drive moving member 17 along guide rail 16
It is moved forward or rearward.
Wherein, float layer 4 uses speciality rubber, and elastic packing performance is good, is used for multiple times and is less prone to fatigue cracking, very well
Solve the problems, such as rigidity push deformation it is small, be advantageous to sealant 7 and be bonded with the better seal of workpiece 12 to be detected；Float layer
Multiple filling parts 11 are provided among 4, because 12 inner spaces of workpiece battery collet to be detected are larger, therefore in float layer 4
Between the filler 11 of the highly dense property of multiple lightweights, the confined air anaplasia that such sealing mechanism 24 encloses with workpiece 12 to be detected are set
It is small, so that helium during detection toward required filling in confined space tails off, and then reduce experimental period, save experimental cost.
(inert gas is poured in experiment and carries out gas leakage detection).Negative pressure and malleation test, big closed space body are carried out in experiment
Product can lengthen the testing time, while big volume needs to pour more inert gases, cost of idleness, is contracted using special filler
Short experimental period, save experimental cost.
The air-tightness detection device of the utility model battery collet also includes the controlling organization that control cylinder and motor open and close
23。
The course of work of the utility model device：Workpiece is in place；Frock promotes sealant fitting；Vacuum generator is opened
Beginning takes out negative pressure to die cavity to 0.02Mpa, pressurize 30 seconds, it is determined that without big leakage；Helium is poured in toward die cavity, carries out leakage helium
Inspection；Detection terminates.
The workpiece battery collet 12 to be detected to get off from robot gripper is accepted by support mechanism 22, and robot gripper will be treated
Detection workpiece battery collet 12 is placed in support mechanism 22, and now four supporting parts 15 are respectively positioned at locating part 13, so as to ensure
The top of four supporting parts 14 is located in same level, starts cylinder 14, and cylinder 14 drives supporting parts 15 to move down, mobile
Overlapped to workpiece battery collet 12 (25 at sealing) to be detected and the sealant 7 of sealing mechanism 24；Start the motor of actuating unit
18, ball screw 19 rotates, and the sliding sleeve 20 being set in outside ball screw 19 drives moving member 17 to be moved forward along guide rail 16, directly
It is stuck in the upper end of moving member 17 on workpiece 12 to be detected and plays limitation workpiece 12 to be detected and move up；Start jacking cylinder
5, jacking cylinder 5 promotes border structure 3 to move upwards until sealant 7 is brought into close contact with workpiece 12 to be detected, with border structure 3
The float layer 4 (outer edge) that backplane level 6 is fixedly connected is as moving up for border structure 3 is stretched, due to the elasticity of float layer 4
Good seal performance, therefore it can be avoided by rigid drawing crack in the seal process that exerts a force, if in addition workpiece 12 to be detected with sealing
Layer 7 junction out-of-flatness or post welding distortion be present, have flexible sandwich 9 sealant 7 also can well with it is to be checked
Survey the palette of workpiece 12；Sealant 7 is with after the palette of workpiece 12 to be detected, extracting the air in confined space, making wherein
Negative pressure (now barometric reading is negative pressure 0.02Mpa in confined space) is formed, pressurize again reads off barometric after 30 seconds
Reading, if barometric reading does not change substantially, illustrate no big air leakage point；Then toward filling helium in confined space
Gas, carry out Lou helium with Nitrogen Detector after filling and detect, if leakage helium phenomenon occurs, Nitrogen Detector can alarm；After detection terminates,
The motor 18 of actuating unit is again started up, ball screw 19 inverts, and the sliding sleeve 20 being set in outside ball screw 19 drives moving member
17 are moved rearwards along guide rail 16, restart cylinder 14, and cylinder 14 drives supporting parts 15 to move up, so as to drive work after detection
Part 12 moves up, and when supporting parts 15 are moved at locating part 13, robot gripper takes the workpiece 12 detected away.
