Specific embodiment
The application is further described with the following Examples.
A kind of specific embodiment of plastic product welding system of the application, as depicted in figs. 1 and 2, including：For fixing
The stationary fixture 1 of product to be welded and the main control module 8 of control welding process, are provided with temperature knowledge on the stationary fixture 1
Other device, the temperature recognition device obtains the temperature information of product to be welded and the temperature information is sent to into main control module
8, the main control module 8 selects corresponding welding scheme according to the temperature information.
In the present embodiment, the stationary fixture 1 includes upper mould 5, lower mould 6 and for driving lower mould 6 vertically reciprocal
The lower die driving device 7 of motion, the temperature recognition device is fixed on the upper mould 5.During work, product is fixed on into lower mould 6,
Lower die driving device 7 drives lower mould 6 to move up as the matched moulds of upper mould 5, and at this moment temperature recognition device just can be accurately right
Quasi- identification point.Move up and down because upper mould 5 is not driven substantially, thus temperature recognition device is fixed on into upper mould 5 can be effective
Reduce due to moving up and down brought vibrations, and then avoid, due to displacement caused by vibrations, improving the accuracy of temperature detection.
The temperature recognition device includes the infrared temperature induction apparatuss being fixed on the stationary fixture 1, the infrared temperature

Step A：Judge whether stationary fixture 1 reaches welding post, if it is, performing next step；
Step B：The product temperature value of the infrared temperature induction apparatuss detection of product is obtained, judges the value whether in preset temperature
In the range of, if it is not, then terminate welding process, if it is, judging whether more than preset temperature value, if greater than preset temperature
Value, then judge the product for hot product, if less than preset value, then judges that the product is cold product；
Step C；By barcode scanner 4 obtain product processing time information, calculate process time information and it is current when
Between time difference, if the time difference be more than Preset Time difference, judge that the product is cold product, if the time difference is less than
Preset Time difference, then judge the product for hot product；
Step D：Whether contrast step B is consistent with the judged result of step C, if unanimously, next step is performed, if not
Unanimously, welding process is interrupted；
Step E：If fruit product is hot product, call the first welding scheme and start welding, such as fruit product is cold product, is adjusted
With the second welding scheme and start welding.Specifically, the main distinction of the first welding scheme and the second welding scheme can be weldering
Connect the difference in parameter, such as heating-up temperature parameter, welding pressure parameter, weld interval.
Need to remark additionally, in above step B to step D, it is also possible to only with step B or step C, namely
Only use a kind of temperature recognition methodss.
To sum up, compared with prior art, this welding system and welding method in welding process due to having taken into full account product
Impact of the temperature to welding effect, selects suitable welding scheme, so as to effective in welding process according to the temperature of product
Ensure that welding quality.
Finally it should be noted that above example is only illustrating the technical scheme of the application, rather than the application is protected
The restriction of shield scope, although having made to explain to the application with reference to preferred embodiment, one of ordinary skill in the art should
Work as understanding, the technical scheme of the application can be modified or equivalent, without deviating from the reality of technical scheme
