The cooling air outlet of the cooling machine 1 is communicated with the cover 2, so that cold air is continuously sent into the cover 2. The input end of the jig stop lifting conveying mechanism 3 is connected with the output end of a previous process, the output end of the jig stop lifting conveying mechanism 3 is connected with the input end of a next process, the stop lifting end of the jig stop lifting conveying mechanism 3 is located directly below the jig temporary storage rack 5, the stop lifting end of the jig stop lifting conveying mechanism 3 and the jig temporary storage rack 5 are located in the working area of the jig reflow lifting mechanism 4, the input end of the jig reflow conveying mechanism 6 is connected with the output end of an empty jig of the next process, and the output end of the jig reflow conveying mechanism 6 is connected with the recovery end of an empty jig of a previous process. The jig stop lifting conveying mechanism 3 is used for receiving a jig 7 with high temperature and carrying a PCB board output by a previous process, and conveying the jig 7 to the jig reflow lifting mechanism 4 and a next process in sequence. The jig reflow lifting mechanism 4 is used for driving the jig 7 to move between the lifting end of the jig stop lifting conveying mechanism 3 and the jig temporary storage rack 5, so that the jig 7 with high temperature and carrying the PCB board on the jig stop lifting conveying mechanism 3 is stored on the jig temporary storage rack 5 to cool, and the jig 7 carrying the PCB board after cooling is sent back to the jig stop lifting conveying mechanism 3. In addition, when the jig stop lifting conveying mechanism 3 conveys the jig 7 to the stop lifting end, the conveying is stopped and the jig 7 is lifted, so that the jig reflow lifting mechanism 4 obtains the jig 7. The jig reflow conveying mechanism 6 is used for recovering the empty jig 7 of the next process to the previous process, so as to achieve the purpose of recycling the jig 7.

[0036] Working principle:

[0037] The jig stop lifting conveying mechanism 3 receives the jig 7 with high temperature and carrying a PCB board output by a previous process, and when the jig stop lifting conveying mechanism 3 conveys the jig 7 to the stop lifting end, the conveying is stopped and the jig 7 is lifted. Then the jig reflow lifting mechanism 4 conveys the lifted jig 7 to the jig temporary storage rack 5 for temporary storage, and the above operation is repeated until the jig temporary storage rack 5 is full of the jigs 7. Then the cooling machine 1 is started, the cooling machine 1 continuously sends cold air into the cover 2 to cool the jigs 7 temporarily stored in the jig temporary storage rack 5. After cooling and receiving, the jig reflow lifting mechanism 4 conveys the jigs 7 in the jig temporary storage rack 5 to the stop lifting end of the jig stop lifting conveying mechanism 3 in sequence, and the jig reflow lifting mechanism 4 outputs the jigs 7 to a next process.

[0038] When the PCB board on the jig 7 is removed by a next process, the jig reflow conveying mechanism 6 receives the empty jig 7 of the next process after the PCB board is removed, and conveys the empty jig 7 to a previous process for recovery, so as to achieve the purpose of recycling the jig 7.

[0039] Referring to Figure 3 、 Figure 4 In the embodiment, the jig stopping and lifting conveying mechanism 3 comprises a jig conveying line 301 for conveying the jig 7, a lifting assembly 302 for lifting the jig 7, and a stopping cylinder 303. The input end of the jig conveying line 301 is connected with the output end of the previous process, the output end of the jig conveying line 301 is connected with the input end of the next process, the lifting assembly 302 is arranged below the stopping and lifting end of the jig conveying line 301, and the stopping cylinder 303 is arranged vertically upward below the stopping and lifting end of the jig conveying line 301. The extension end of the stopping cylinder 303 is provided with a stopping plate 3031, and the stopping plate 3031 is provided with a sensor for detecting whether the jig 7 reaches the stopping and lifting end of the jig conveying line 301. After the jig conveying line 301 receives the jig 7 with high temperature and carrying the PCB board conveyed from the previous process, the jig 7 is driven to move to the output end, and at this time, the stopping plate 3031 of the stopping cylinder 303 is extended. When the jig 7 collides with the sensor on the stopping plate 3031, the jig conveying line 301 stops conveying, the lifting assembly 302 starts, and the jig 7 is lifted upward to leave the conveying belt of the jig conveying line 301, so as to be obtained by the jig reflow lifting mechanism 4. The jig stopping and lifting conveying mechanism 3 realizes the connection of the previous process, the next process and the jig reflow lifting mechanism 4 through the jig conveying line 301, the lifting assembly 302 and the stopping cylinder 303, and sequentially conveys the jig 7 conveyed from the previous process to the jig reflow lifting mechanism 4 and the next process, and has compact structure and small space occupation.

[0040] Specifically, the jig conveying line 301 comprises a first fixed frame 3011, a first conveying motor 3012, a first synchronous part 3013, two first conveying belts 3014 movably arranged on the upper ends of the two side plates of the first fixed frame 3011, and the first conveying motor 3012 is fixed with the first fixed frame 3011. The output shaft of the first conveying motor 3012 is connected with one of the first conveying belts 3014 and drives it to rotate, and the two first conveying belts 3014 rotate synchronously through the first synchronous part 3013. When the jig conveying line 301 operates, the first conveying motor 3012 is started to drive the first conveying belt 3014 connected therewith to rotate, and the first conveying belt 3014 drives the other first conveying belt 3014 to rotate synchronously through the first synchronous part 3013, so that the two first conveying belts 3014 receive the jig 7 carrying the PCB board from the previous process and sequentially convey the jig 7 to the jig reflow lifting mechanism 4 and the next process.

[0041] Specifically, the lifting assembly 302 includes a vertically upward-facing lifting cylinder 3021 and a lifting platform 3022 disposed above the lifting cylinder 3021. The telescopic end of the lifting cylinder 3021 is connected to the bottom of the lifting platform 3022, driving the lifting platform 3022 up and down. When the jig 7 stops at the stop lifting end of the jig conveyor line 301, the lifting cylinder 3021 is activated, and the lifting platform 3022 lifts the jig 7 upward, allowing the jig 7 to leave the conveyor belt of the jig conveyor line 301 so that it can be retrieved by the jig return lifting mechanism 4.

[0042] Furthermore, in order to enable the lifting assembly 302 to lift the jig 7 more stably, the lifting assembly 302 also includes two linear guide assemblies respectively arranged on the left and right sides of the bottom of the lifting platform 3022, and the linear guide assembly includes a vertically arranged linear guide rod 3023 and a linear bearing slider 3024. A bearing mounting hole for connecting the corresponding linear bearing slider 3024 is provided on the bottom of the first fixed frame 3011. The upper end of the linear guide rod 3023 is connected to the bottom of the lifting platform 3022, and the lower end of the linear guide rod 3023 passes through the corresponding linear bearing slider 3024 and can move up and down along the linear bearing slider 3024.

[0043] See also Figure 5 、 Figure 6 In this embodiment, the jig return and lifting mechanism 4 includes a jig fork 401, a fork telescopic module 402, a lifting platform 403, and a lifting module 404.

At the same time, a positioning block 4011 is provided at the end of the jig fork 401 for positioning the jig 7. The positioning block 4011 can prevent the jig 7 from shifting relative to the jig fork 401 when the jig fork 401 moves the jig 7, or the jig 7 from falling off the jig fork 401, causing the equipment to malfunction.

[0044] When storing the jig 7, the lifting module 404 drives the lifting platform 403 to descend to the height of the jig stop lifting and conveying mechanism 3, and then the fork telescopic module 402 extends the jig fork 401. After it is fully extended, the lifting module 404 drives the lifting platform 403 to rise a short distance, and lifts the jig 7 on the jig stop lifting and conveying mechanism 3. After lifting, the fork telescopic module 402 retracts the jig fork 401. After retraction, the lifting module 404 drives the lifting platform 403 to rise to the height of the jig temporary storage rack 5, and then the fork telescopic module 402 extends the jig fork 401. After it is fully extended, the lifting module 404 drives the lifting platform 403 to descend a short distance, so that the jig 7 on the jig fork 401 is temporarily stored on the jig temporary storage rack 5, and then the fork telescopic module 402 retracts the jig fork 401. The above steps are repeated until the jig temporary storage rack 5 is full of jigs 7.

[0045] When taking the fixture 7, the lifting module 404 drives the lifting platform 403 to rise to the height of the fixture temporary storage rack 5, and then the fork telescopic module 402 extends the fixture fork 401. After it is fully extended, the lifting module 404 drives the lifting platform 403 to rise a short distance, and lifts the fixture 7 on the fixture temporary storage rack 5. After lifting, the fork telescopic module 402 retracts the fixture fork 401. After retraction, the lifting module 404 drives the lifting platform 403 down to the fixture stop lifting conveyor. The fork telescopic module 402 extends the jig fork 401. After it is fully extended, the lifting module 404 drives the lifting platform 403 to descend a short distance, so that the jig 7 on the jig fork 401 stops on the jig stop lifting and conveying mechanism 3. Then the fork telescopic module 402 retracts the jig fork 401, and the jig stop lifting and conveying mechanism 3 conveys the jig 7 to the next process. Repeat the above steps until all the jigs 7 on the jig temporary storage rack 5 are taken out.

[0046] The fixture reflux lifting mechanism 4 can realize the vertical transportation of the fixture 7 through the fixture fork 401, fork telescopic module 402, lifting platform 403 and lifting module 404 set above, so that the structure of the equipment can be set more compactly and the space occupied by the equipment can be reduced.

[0047] Specifically, the fork telescopic module 402 includes a driving motor 4021, a transmission belt arranged transversely along the telescopic direction of the jig fork 401, two slide rails 4022 arranged along the telescopic direction of the jig fork 401, and a slide block connecting plate 4023.

When the jig fork 401 is extended, the driving motor 4021 drives the transmission belt to rotate forward, the transmission belt drives the slide block connecting plate 4023 to move forward along the two slide rails 4022 through the belt connecting piece, and the slide block connecting plate 4023 drives the jig fork 401 to extend forward. When the jig fork 401 is retracted, the driving motor 4021 drives the transmission belt to rotate reversely, the transmission belt drives the slide block connecting plate 4023 to move backward along the two slide rails 4022 through the belt connecting piece, and the slide block connecting plate 4023 drives the jig fork 401 to retract backward. The fork telescopic module 402 arranged above can realize stable extension or retraction of the jig fork 401.
