The specific embodiment of Workpiece detecting device is described in detail below.Specifically, Fig. 2 is the embodiment of the present invention
Partial sectional view of the reaction chamber of offer in no piece.Fig. 3 is reaction chamber provided in an embodiment of the present invention when there is piece
Partial sectional view.Referring to Figure 2 together and Fig. 3, pedestal 2 is provided in reaction chamber, for carrying pallet 1, and at this
The bottom of reaction chamber is provided with Workpiece detecting device, central axis 6, upper flange 5, lower flange 8 and bellows 7.Wherein, workpiece is examined
Surveying device includes probe 3, compressed spring 10 and detection switch, wherein detection switch includes stationary contact 14 and movable contact 13, the two
The digital signal in relation to being is issued when being in contact, i.e. physical state corresponding to the digital signal indicates to be placed with support on pedestal
Disk;The two is issued when mutually separating in relation to no digital signal, i.e., physical state corresponding to the digital signal indicates on pedestal
It is not placed with pallet.Preferably, stationary contact 14 is connect with DC power supply 15, when movable contact 13 and stationary contact 14 are in contact, two
Power on circuitry where person;When movable contact 13 is mutually separated with stationary contact 14, down circuitry where the two, so as to by stationary contact
14 are used as digital signal with the presence or absence of both physical states of voltage, it may be assumed that if there are voltages for stationary contact 14, then it represents that put on pedestal
It is equipped with pallet;If voltage is not present in stationary contact 14, then it represents that be not placed with pallet on pedestal.Additionally, it is preferred that, reaction chamber is also
Including control unit, for reading the digital signal issued by Workpiece detecting device, and judged on pedestal according to the digital signal
Whether pallet is placed with.Certainly, in practical applications, it can also manually read and judge whether be placed with pallet on pedestal.
It is provided with the second through-hole on the chamber wall 16 of reaction chamber bottom, is protruded into reaction chamber with for probe 3.And
And the first through hole through its thickness is provided on the loading end of pedestal 2, probe 3 is located in the first through hole, and its lower end
It is connect with the upper end for the central axis 6 being vertically arranged, the lower end of central axis 6 is connect with lower flange 8;Lower flange 8 is by compressed spring 10
Carrying, and connect with movable contact 13.Specifically, the setting of compressed spring 10 (can be the outer of detection switch in fixed bracket 11
Shell) on, lower flange 8 and the central axis 6 being attached thereto and probe are carried by compressed spring 10.When there is no pallet 1 on pedestal 2
When, in a state of nature, the upper end of probe 3 is higher than the loading end of pedestal 1 to compressed spring 10, and movable contact 13 is located at and stationary contact at this time
At the position of point 14 phases separation, as shown in Figure 2.When pallet 1 is placed on the loading end of pedestal 2, pallet 1 utilizes itself weight
Power is downwardly against probe 3, and probe 3 drives movable contact 13 to be displaced downwardly at the position being in contact with stationary contact 14, while compressed spring
10 are compressed, as shown in Figure 3.When pallet 1 is taken out from pedestal 2, compressed spring 10 pushes up laxative remedy using own resilient
Orchid 8 and the central axis 6 and probe that are attached thereto synchronize move up, thus make probe 3 again on move to the upper end and be higher than holding for pedestal 1
At the position of section, while movable contact 13 is located at again at the position separated with 14 phase of stationary contact.

It is sealed.Bellows 7 is around being set in around central axis 6, and between upper flange 5 and lower flange 8, and respectively with two
Person is tightly connected.In this way, vacuum state is in inside the inside of reaction chamber and bellows 7, and detection switch and laxative remedy
The position of 5 connection of orchid has switched to atmospheric condition, thereby may be ensured that the cable of acquisition signal can smoothly be connect with detection switch.
Preferably, lower flange 8 is used with movable contact 13 and is detachably connected, to avoid rigid connection to component
Bring impact.It is further preferred that being provided with sphere-contact portion 9 in the bottom of lower flange 8, and corresponding on movable contact 13
It is vertically arranged with contact bar 12, the upper surface of contact bar 12 is plane.When pallet 1 is placed on the loading end of pedestal 2, ball
Surface contact part 9 is in contact with the upper surface of contact bar 12, since the upper surface of sphere-contact 9 and contact bar 12 is sphere-contact,
This can still make sphere-contact portion 9 connect with the contact holding of bar 12 under the premise of allowing lower flange 8 to tilt certain angle
Touching, and can to avoid probe 3, central axis 6 and contact bar 12 generate bending stress, so as to improve equipment stability and can
By property.
Preferably, probe 3 is using the production of the insulating materials of ceramics or quartz etc., the probe 3 of insulating materials with support
It when disk 1 is in contact, will not be conducted with pallet 1, to will not be had an impact to the field distribution inside reaction chamber.
Preferably, the upper surface of probe 3 has circular arc chamfering, with realization and pallet smooth engagement, thus will not be to pallet
It causes to scratch.In addition, the material of pallet may include aluminium or silicon carbide etc., and the gravity of pallet should meet: by pallet
When placing on the base, probe can be pushed using self gravity, so that movable contact moves down, and be in contact with stationary contact.
Fig. 4 is the biography piece flow diagram of reaction chamber provided in an embodiment of the present invention.As shown in Figure 4, it will be held in the palm in manipulator
Disk is passed to before reaction chamber, and software systems (i.e. control unit) (can be counted by directly reading the DI value of Workpiece detecting device
Word signal value) judge whether to have in reaction chamber piece, and after manipulator completes film releasing movement, software systems are led to again
The DI value for reading Workpiece detecting device is crossed, state, which is updated in reaction chamber, piece state.Due to Workpiece detecting device
So as to accurately and judge whether there is pallet in reaction chamber in time, and then equipment can be improved in DI value true and accurate
Reliability.
