The support mechanism 2 includes a support component, the support component forms a slide groove 21, and the adsorption component releases the adsorbed resistor 20 into the slide groove 21. The push mechanism 3 includes a push component, and the push component includes a slider 31. The slider 31 reciprocates relative to the slide groove 21 to push the resistor 20 to move along the first direction in the slide groove 21. The shift mechanism 4 is used to apply a moving force to the resistor 20 to move along the first direction. The limiting mechanism 5 is used to detachably fix a frame 30, and the resistor 20 is pushed into the frame 30. The fixing mechanism 6 is used to fix the resistor 20 that has been pushed into the frame 30.

Therefore, the resistor chip assembly device of the present invention has the advantages of high efficiency, accuracy and reliability for the assembly of the resistor chip 20.

[0032] Please refer to Figures 1 to 3Specifically, the driving assembly includes a lifting cylinder 11 and a rotating cylinder 12, and the adsorption assembly includes a rotating rod 13 and an adsorption head 14. The two ends of the rotating rod 13 are respectively connected to the rotating cylinder 12 and the adsorption head 14. The lifting cylinder 11 drives the lifting of the rotating cylinder 12, and the rotating cylinder 12 drives the rotation of the rotating rod 13 to enable the adsorption head 14 to adsorb and release the resistor 20. In this way, the suction mechanism 1 can adapt to the chute 21 in different directions and accurately release the resistor 20 into the chute 21. In particular, the suction mechanism 1 can use the lifting cylinder 11 and the rotating cylinder 12 to move the adsorption head 14 to the relative position with the feeding mechanism 9, the identification mechanism and the recovery mechanism 10 (which will be further described below) to achieve different functions of adsorption, identification and recovery of the resistor 20, so that various functions can be achieved with high automation and reliability.

[0033] Please refer to Figure 4 and Figure 5 Specifically, the support assembly includes a support block 22, a pair of support plates 23 and a pair of fixed plates 24, the pusher assembly includes a first driving cylinder 32, the piston rod of the first driving cylinder 32 is drivingly connected to the slider 31, the slider 31 includes a block body 311 and a slide plate 312, a block groove 221 is provided in the support block 22, a pair of support plates 23 are provided with protruding plates 231 which protrude relative to each other and are suspended above the block groove 221, the protruding plates 231 are located at the lower part of the corresponding support plate 23 close to the support block 22, and the slide groove 21 is formed between the pair of support plates 23 and Located above the two protruding plates 231, the fixing plate 24 fixes the supporting plate 23 on the supporting block 22, and there is a spacing space between the two protruding plates 231. The resistor 20 is slidably supported on the two protruding plates 231, and the block body 311 reciprocates in the spacing space to make the slide plate 312 reciprocate on the two protruding plates 231. The first driving cylinder 32 drives the block body 311 to reciprocate and return to its original position after pushing the resistor 20 into the skeleton 30, thereby providing an empty chute 21 again to receive the resistor 20 released by the adsorption head 14 again. In this way, through the specific arrangement of the above-mentioned supporting assembly and the pushing assembly, the resistor 20 located in the chute 21 can be smoothly and reliably moved to the accurate position of the skeleton 30.

[0034] Please refer to Figures 4 to 7Specifically, the limiting mechanism 5 includes a positioning plate 51 and a first spring-pressing assembly 52. ​​The first spring-pressing assembly 52 includes a first pressing block 521, a plurality of first pressing columns 522, a plurality of first elastic members 523 respectively sleeved on the outer periphery of a first pressing column 522, and a first limiting plate 524. The positioning plate 51 and the first limiting plate 524 are arranged opposite to each other in the first direction and a limiting groove 53 is formed therebetween. The first pressing block 521 receives a first pressing force which is parallel and equivalent to the first direction and the elastic restoring force of the first elastic member 523, so that the first pressing column 522 applies a force to the first limiting plate 524 to limit the skeleton 30 to maintain a constant position in the limiting groove 53. After the first pressing force is no longer applied, the first pressing block 521 can be relatively away from the positioning plate 51 along the first direction. Therefore, by adopting the above-mentioned first spring-pressing assembly 52, the orientation of the skeleton 30 in the first direction can be reliably maintained so as to ensure that the resistor 20 moves to the accurate position in the skeleton 30, and the skeleton 30 can be easily taken out in the subsequent process.

[0035] Please refer to Figures 4 to 9 Specifically, the fixing mechanism 6 includes a pair of connecting plates 61, a first supporting plate 62 and a first fixing assembly 63. The pair of connecting plates 61 are fixedly connected to the two sides of the supporting block 22 respectively, the first supporting plate 62 is fixedly connected to the pair of connecting plates 61, the first fixing assembly 63 includes a second driving cylinder 631 and a first fixing member 632, and the limiting mechanism 5 also includes a second spring pressing assembly 54. The second driving cylinder 631 drives the first fixing member 632 to move in the second direction. The movement of the first fixing member 632 in the second direction by the second driving cylinder 631 can avoid friction or interference with the resistor sheet 20 and can adapt to resistor sheets 20 of different thicknesses. The second direction is perpendicular to the first direction. In this embodiment, the first direction is the horizontal direction and the second direction is the vertical direction. The second spring-pressing assembly 54 includes a second pressing block 541, a plurality of second pressing columns 542, a plurality of second elastic members 543 respectively sleeved on the outer periphery of a second pressing column 542, and a second limiting plate 544. The second pressing block 541 receives a second pressing force parallel to the second direction and an elastic restoring force of the second elastic member 543, so that the second pressing column 542 applies a force to the second limiting plate 544 so that the second limiting plate 544 and the first fixing member 632 respectively press the two sides of the skeleton 30 in parallel to the second direction to keep their positions unchanged. After the second pressing force is no longer applied, the second pressing block 541 can be relatively away from the first fixing member 632 in the second direction. In this way, by using the second spring-pressing assembly 54 and the first fixing member 632 to relatively press the resistor 20, the position of the resistor 20 in the skeleton 30 can be reliably maintained accurately, and the skeleton 30 can be easily removed in the subsequent process. The position of the resistor 20 in the skeleton 30 can also be fixed by the first fixing member 632.

[0036] Please refer to Figure 8 and Fig. 9 Specifically, the fixing mechanism 6 further includes a second support plate 64 and a second fixing assembly 65, the second support plate 64 is fixedly connected to a pair of connecting plates 61, the first support plate 62 and the second support plate 64 are relatively fixed above and to the side of the pair of connecting plates 61, respectively, the second fixing assembly 65 includes a third driving cylinder 651 and a second fixing member 652, the piston rod of the third driving cylinder 651 is drivingly connected to a transmission plate 66, the second fixing member 652 is fixedly connected to the transmission plate 66, and the third driving cylinder 651 drives the second fixing member 652 to move parallel to the second direction. Therefore, by using the third driving cylinder 651 to move the second fixing member 652 in the second direction, not only can the friction or interference with the resistor 20 be avoided and the resistor 20 with different thicknesses can be adapted, but also the resistor 20 can be provided with stable support.

[0037] Please refer to Figure 1 to Figure 2. Specifically, the shifting mechanism 4 includes a first roller 41 and a second roller 42. The resistor assembly device also includes a limiting frame 7 arranged between the first roller 41 and the frame 30. The limiting frame 7 is provided with a pair of elastic arms 71 and a slot 72 located below the elastic arms 71. The first roller 41 is arranged between a supporting plate 23 and an elastic arm 71. The first roller 41 cooperates with the slide plate 312 to move the resistor 20 pushed thereunder to the limiting slot 53. The slot 72 moves the resistor 20 pushed thereunder by the first roller 41 to the limiting slot 53. 20 is limited and allowed to pass, the elastic arm 71 applies elastic pressure to the resistor 20 in the direction of the slot 72, the second roller 42 is arranged on the transmission plate 66, the second roller 42 and the second fixing member 652 are successively in contact with the resistor 20, the second roller 42 further moves the resistor 20 that has been sent into the limiting slot 53 into place, the second fixing member 652 presses the resistor 20 that has been moved into place, the first fixing member 632 and the second fixing member 652 fix the resistor 20 by pressurization, heating or / and dispensing. In this way, the first roller 41 and the second roller 42 can apply friction to the relative front and back surfaces of the resistor 20 to make the movement of the resistor 20 along the first direction smoother, and the limiting frame 7 can better limit the movement of the resistor 20. After the second roller 42 moves the resistor 20 into position, the second fixing member 652 moves downward under the drive of the third driving cylinder 651 to press the resistor 20, thereby avoiding the friction of the second fixing member 652 on the resistor 20 and aligning the resistor 20 with the preset position to fix it to the frame 30.

[0038] Please refer to Figure 2 , Figure 4 and Figure 5Specifically, the resistor assembly device further comprises a moving mechanism 8, the moving mechanism 8 comprises a fourth driving cylinder 81, a moving block 82, a moving plate 83, a pair of guide grooves 84 and a pair of legs 85, the piston rod of the fourth driving cylinder 81 is drivingly connected to the moving block 82, one side of the moving plate 83 is fixedly connected to the moving block 82, the other side of the moving plate 83 supports the supporting block 22 and the first driving cylinder 32, one end of the pair of legs 85 is fixedly connected to the moving plate 83 and the other end is respectively slidably connected to a guide groove 84, and the fourth driving cylinder 81 drives the moving plate 83 to reciprocate parallel to the first direction. In this case, the moving mechanism 8 is used to drive the supporting mechanism 2 and the pushing mechanism 3 to relatively abut against and away from the limiting mechanism 5 along the first direction, so that the limiting mechanism 5 can make a relative rotation to drive the skeleton 30 without the resistor 20 to dock and cooperate with the supporting mechanism 2 and the pushing mechanism 3 without interference, and drive the skeleton 30 with the resistor 20 installed to move away from the supporting mechanism 2 and the pushing mechanism 3 to accept the production of the next process.

[0039] Please refer to Figure 1 and Figure 2 Specifically, the resistor chip assembly device also includes a feeding mechanism 9, an identification mechanism and a recovery mechanism 10. The feeding mechanism 9 includes a support 91, a fifth driving cylinder 92 and a support plate 93. The support plate 93 is connected to the piston rod of the fifth driving cylinder 92. The support plate 93 is provided with a die groove 931 for accommodating the resistor chip 20. The fifth driving cylinder 92 drives the support plate 93 to reciprocate relative to the adsorption head 14. Therefore, the feeding mechanism 9 can continuously supply the resistor chip 20 to the suction mechanism 1 in a highly automated manner. The die groove 931 is used to receive the resistor chip 20. The identification mechanism includes a visual detector. The visual detector has a machine vision function. The visual detector is arranged in the die groove 93. 1 and is used to identify whether the resistor 20 in the mold groove 931 is qualified. The recycling mechanism 10 includes a recycling box 101 and a guide rack 102.
