Figure, for the ease of showing the separated state of shaft of the positioning fixed mechanism wherein link block 53 and positioning cylinder 50.
Refering to fig. 12, the limit blocking mechanism includes the second driving that stopper 47, the driving stopper 47 are gone up and down
Device 46 and mounting blocks 49, the mounting blocks 49 have a support arm 48 to extend outwardly, and second driving device 46 is solid
Due on the support arm 48, and the driving end of second driving device 46 is arranged straight down, and the stopper 47 is fixed on
The driving end of second driving device 46, the stopper 47 are located at the surface of the delivery platform 18 transmission terminal, institute
State the second driving fill 46 set for drive the stopper 47 move down until it is close or contradict delivery platform 18, for stopping
The pallet 19 continues transmission with location tray 19；Specifically, second driving device 46 is cylinder.
Refering to Fig. 7 to Figure 11, the machine for arranging screws includes feed bin 32, feed turntable 35, the first vacuum generator 39, the
Two vacuum generators 43 and for drive it is described feed turntable 35 rotate driving device；The feed bin 32 is for accommodating screw；
The feed turntable 35 is set to the side in the feed bin 32, and inclined or be vertically arranged；The periphery of the feed turntable 35
Multiple through-holes 36 are evenly distributed on face, the screw rod of the through-hole 36 and the screw matches, and can accommodate the spiral shell just
The screw rod of silk；In 35 rotation process of feed turntable:
Refering to fig. 10, there are two operating positions for these through-holes 36 tool: suction operating position and detection Charge motion position；Rotation is extremely
Just the through-hole 36 being connected to below feed turntable 35 and with second vacuum generator 43 is in suction operating position, at this time
Through-hole 36 is material sucking port 42, and the material sucking port 42 is for screw to be adsorbed in its hole；It is above rotation to feed turntable 35 and proper
The good through-hole 36 being connected to first vacuum generator 39 is in detection Charge motion position, and through-hole 36 at this time is that detection supplies
Material mouth 41, the detection inlet 41 are used for the screwed lock machine feeding screw, and the detection inlet 41 and the first vacuum are sent out
Pressure switch 40 is additionally provided on the pipeline that raw device 39 is connected to, the pressure switch 40 is for detection detection feed in the operating condition
The negative pressure value of mouth 41 judges to detect whether inlet 41 is adsorbed with screw with this；The quantity of the through-hole 36 is greater than or waits at this time
In two；
Alternatively, refering to fig. 11, there are three operating positions for these through-holes 36 tool: suction operating position, detection operating position and feed
Operating position；Just the through-hole 36 being connected to below rotation to feed turntable 35 and with second vacuum generator 43 is in suction
Operating position, through-hole 36 at this time are material sucking port 42, and the material sucking port 42 is for screw to be adsorbed in its hole；Rotation is extremely fed
Just the through-hole 36 being connected to above turntable 35 and with first vacuum generator 39 is in detection operating position, through-hole at this time
36 be detection mouth 44, is additionally provided with pressure switch 40 on the pipeline that the detection mouth 44 is connected to the first vacuum generator 39, described
Pressure switch 40 judges whether detection mouth 44 is adsorbed with spiral shell for detecting the negative pressure value of detection mouth 44 in the operating condition with this
Silk；The feed turntable 35 is in Charge motion from the detection mouth 44 rotation to the next through-hole 36 adjacent with detection mouth 44
Position, through-hole 36 at this time are inlet 45, and the inlet 45 is used for the screwed lock machine feeding screw；The through-hole at this time
36 quantity is greater than or equal to three.
It should be understood that due to frequently occurring back suction phenomenon, back suction, that is, spiral shell mentioned here in practical work process
Silk nut head be sucked by material sucking port, however due under the mutual cooperation suction between electrostatic or material, both made from
There is no negative pressure of vacuum effect still can be sent to inlet 41 after opening material sucking port 42, and then pressure switch 40 is caused to be judged by accident, causes
All adverse consequences brought by the still normal feeding of this screwed lock machine, the design of scraping brush 34 is convenient for solution real work
Occur back suction phenomenon in journey, feed turntable will be scraped off by the screw of back suction before being sent to inlet 41 by scraping brush 43
35, it can effectively avoid because back suction leads to all adverse consequences of the bring of the erroneous judgement of pressure switch 40, effectively by required screw

Free 24 stress of slide unit of XY is mobile, in free 24 moving process of slide unit of the XY, can be measured often by the rangefinder 28
The pitch offset of mobile front and back between the rangefinder 28 of a detection plane 27 corresponding thereto, so that it is determined that tightening axle bottle opener out
The centre coordinate of head rotation center；Specifically, the rangefinder 28 is laser range sensor, ultrasonic distance measurement senses, is infrared
Distance measuring sensor or amesdial.
The specific work process or working principle of the present embodiment are as follows:
When carrying out lock pair, it will be placed in feed bin 32 with wait lock the screw that pair screw hole matches in advance, and pass through calibrating device in advance
10 determine the centre coordinate of the tightening axle screwdriver head rotation center of the screwed lock unit 14, compensate the screwed lock list with this
The tool coordinates of member 14；Then start this screwed lock machine, by preparatory setting, in an X-axis mould group 9 and two Y-axis moulds
Under the collective effect of group 11, two the screwed lock units 14 draw lock from machine for arranging screws by vacuum slot thereon respectively
It pays and uses screw, then equally under the collective effect of an X-axis mould group 9 and two Y-axis mould groups 11, two contraposition locks is driven to pay mould
Block is respectively moved to corresponding 6 position of location hole, and is taken pictures detection by CCD camera 15, accurately to adjust two the screwed lock lists
Vacuum slot in member 14 completes corresponding location hole pair finally by two the screwed lock units 14 to corresponding 6 position of location hole
The locking operation of screw hole is answered, two screw synchrolocks is once can be realized and pays, lock is greatly improved and pays efficiency, improve production
Amount, conducive to mass, the needs of large-scale production, assembly.
For above-described embodiment, the present embodiment is explained further and issuable variation is described as follows:
