[0034] The above-mentioned batch patch device for PCB board processing, when in use, arranges the electrical components and PCB boards to be attached in sequence on the conveying device 100, so that the conveying device 100 drives the electrical components and PCB boards to move to the bottom of the adjustment seat 300, and the adjustment seat 300 is controlled by the second drive shaft 230 to move left and right, and the adsorption seat 400 is controlled by the lifting rod 500 to move up and down, so that the bottom end of the adsorption seat 400 can be attached to the surface of the electrical component to be attached.

The two positioning plates 211 are arranged opposite to each other up and down, and the two fixing tubes 212 are arranged at intervals and located between the two positioning plates 211.

The third fixing frame 220 is inserted into the fixing tube 212, and the second drive shaft 230 is installed on the third fixing frame 220.

[0037] Among them, the third fixing frame 220 includes a first folding plate 222 and a second folding plate 223; the two first folding plates 222 are respectively located above the two second fixing frames 210, and the bottom end of the first folding plate 222 is installed with a fixing rod 221, and the fixing rod 221 is inserted into the fixing tube 212. One end of the first folding plate 222 is vertically arranged, and the other end of the first folding plate 222 is bent to fit against the positioning plate 211.

[0038] like Figure 4 As shown, in one embodiment, the adjustment seat 300 includes a first fixing plate 310, a side plate 320 and a fixing block 330; the top of the first fixing plate 310 is lower than the top of the side plate 320, and the two side plates 320 are respectively fixed on both sides of the first fixing plate 310, and the fixing block 330 is fixed to the bottom end of the first fixing plate 310, the top of the fixing block 330 is a plane, and the bottom end of the fixing block 330 is set to an arc surface, and a threaded hole 331 is opened at the end of the fixing block 330 for transmission connection with the second drive shaft 230, and an installation cavity 340 is formed between the fixing block 330 and the side plate 320.

[0039] Specifically, the top end of the side panel 320 abuts against the inner top surface of the second folding plate 223 , and the width between the two side panels 320 is the same as the width of the through-hole 2231 . The air pipe 600 passes through the adsorption seat 400 and the adjustment seat 300 and then passes through the through-hole 2231 .

[0040] like Figure 5As shown, in one embodiment, the adsorption seat 400 includes a clamping block 410 and a second fixing plate 420; a limiting groove 411 is provided at the top of the clamping block 410, and the bottom surface of the limiting groove 411 is set as an arc surface for fitting the fixing block 330, the clamping block 410 is clamped in the installation cavity 340, and the second fixing plate 420 is fixed to the bottom end of the clamping block 410, and a plurality of ventilation grooves 421 are provided at the bottom end of the second fixing plate 420.

[0041] Specifically, when the clamping block 410 is completely clamped in the installation cavity 340 , the top end of the second fixing plate 420 fits with the bottom end of the side plate 320 , forming a complete rectangular structure therebetween.

[0042] In one embodiment, a second mounting hole 350 is provided at the connection between the first fixing plate 310 and the side plate 320. One end of the second mounting hole 350 vertically penetrates to the highest point of the top of the mounting cavity 340. The other end of the second mounting hole 350 is bent upward and faces directly above the first fixing plate 310. The lifting end of the lifting rod 500 is installed in the second mounting hole 350 facing downward, and the other end of the lifting rod 500 is bent and clamped in the second mounting hole 350.

[0043] Furthermore, a plurality of through holes 321 are provided on the side of the side panel 320, and the plurality of through holes 321 are horizontally spaced apart.

The second bend portion 630 is installed in the through hole 321, and one end of the second bend portion 630 is bent downward and connected to the first bend portion 610 through the straight pipe portion 620. There is a gap between the straight pipe portion 620 and the side of the clamping block 410. The other end of the second bend portion 630 is bent upward and connected to the pneumatic equipment through the connecting pipe portion 640.

[0045] Specifically, since there is a gap between the straight tube portion 620 and the side of the clamping block 410, and the distance between the adjustment seat 300 and the adsorption seat 400 will change, when the distance between the adjustment seat 300 and the adsorption seat 400 increases, the two ends of the straight tube portion 620 will be pulled toward the through hole 321 and the third mounting hole 430 respectively, and the main body of the straight tube portion 620 will approach the side of the clamping block 410.

[0046] In one embodiment, a batch placement method for PCB board processing is applied to the batch placement device for PCB board processing in any of the above embodiments, comprising the following steps:

[0047] The electrical components and PCB boards to be attached are placed on the conveying device in sequence, so that the conveying device drives the electrical components and PCB boards to move to the bottom of the adjustment seat.

[0048] The adjustment seat is controlled by the second driving shaft to move left and right, and the adsorption seat is controlled by the lifting rod to move up and down, so that the bottom end of the adsorption seat can be attached to the surface of the electrical component to be attached.

[0049] After the adsorption seat adsorbs the electrical component, it will move to the bottom of the PCB board for placement.

[0050] The above-mentioned batch patch method for PCB board processing is used. When in use, the electrical components and PCB boards to be attached are placed on the conveying equipment in sequence, so that the conveying equipment drives the electrical components and PCB boards to move to the bottom of the adjustment seat. The adjustment seat is moved left and right under the control of the second drive shaft, and the adsorption seat is moved up and down under the control of the lifting rod, so that the bottom end of the adsorption seat can be attached to the surface of the electrical component to be attached. At this time, the adsorption seat adsorbs the electrical component, and the conveying equipment stops conveying during the adsorption process. When the adsorption seat completes adsorption of the electrical component, the conveying equipment continues conveying and moves the PCB board to directly below the adjustment seat. At this time, multiple adjustment seats and adsorption seats are started at the same time to perform patch operations on the PCB board. This patch method can perform large-scale patch operations on electrical components, and has better time-saving and efficiency-increasing effects.
