Description

Technical Field

[0001] The utility model belongs to the technical field of feeding mechanisms, in particular to a feeding mechanism of a photoelectric coupler glue dispensing machine. Background Art

[0002] The material tape needs to be conveyed to the photoelectric coupling dispensing machine through the feeding mechanism of the photoelectric coupler dispensing machine for dispensing. The material tape is sent to the photoelectric coupling dispensing machine through the top pin of the feeding mechanism corresponding to the position of the pinhole of the first section of the material tape. After the dispensing of the first section of the material tape is completed, the feeding mechanism needs to return the top pin to correspond to the position of the pinhole of the second section of the material tape and then continue to convey the material tape. The existing material tapes have a variety of different widths and the positions of the pinholes are also different. Since the position of the top pin of each feeding mechanism is fixed, multiple feeding mechanisms are required when conveying different material tapes.

[0003] In the prior art, a Chinese patent with a reference number of CN 218132995 U discloses a feeding mechanism of a photoelectric coupler dispensing machine, including a mounting plate and a first driving cylinder mounted on the mounting plate, the piston rod of the first driving cylinder moving in a horizontal direction, the end of the piston rod of the first driving cylinder away from the first driving cylinder is fixedly connected to a fixing plate, the fixing plate is fixedly connected to a second driving cylinder, the piston rod of the second driving cylinder moving in a vertical direction, the needle of the utility model can slide to change its position, and can drag different material strips.

[0004] The comparative document provides a feeding mechanism that can adapt to different pinhole intervals on the material belt. However, after the above patent completes the conveyance of a section of the material belt, the feeding mechanism needs to move upward, reset horizontally, move downward, and push horizontally to achieve continuous conveyance of the material belt. This means that the feeding mechanism needs to waste a lot of time after completing the conveyance of a section of the material belt, which is inefficient.

[0005] Therefore, a feeding mechanism of a photoelectric coupler dispensing machine is proposed. Utility Model Content

A fastening nut 49 is screwed on the outer wall of one side of the moving block 44 by threaded engagement. A through groove 491 is opened on the outer wall of one side of the moving table 42 near the outer side of the fastening nut 49, and a scale line 9 is drawn on the outer wall of one side of the moving table 42 near the lower position of the through groove 491. A feeding table 5 is arranged at the lower position of the lifting table 3, and a material belt 6 is arranged on the top of the feeding table 5, and a pinhole 7 is opened on the top of the material belt 6. A guide rod 8 is welded on the top of the lifting table 3, and the guide rod 8 passes through the mounting plate 1.

[0024] It should be noted that, after the existing material belt feeding mechanism completes the conveying of a section of material belt, the feeding mechanism needs to move upward, reset horizontally, move downward, and push horizontally to realize continuous conveying of the material belt. This causes the feeding mechanism to waste a lot of time after completing the conveying of a section of material belt, which is inefficient. In this embodiment, multiple groups of moving blocks 44 at the bottom of the moving table 42 can not only adjust the position of the ejector pin 48 according to the lateral spacing and longitudinal spacing of the pinholes 7 on the material belt 6, so that the feeding structure can convey different types of material belts 6, but also enable the moving table 42 to move horizontally, and the multiple pressing tables 46 can move upward one by one to realize continuous feeding of the material belt 6. Multiple sections of material belt 6 can be fed in one operation, which is efficient.

[0025] Specifically, in the present embodiment, the present scheme mainly includes an ejector position adjustment component 4, which adjusts the position of the ejector 48 according to the lateral spacing and longitudinal spacing of the pinholes 7 on the material belt 6. During the specific adjustment, the second screw moving component 47 is controlled to work, the ball screws on the two second screw moving components 47 rotate, and the ejector 48 on the ball screw moves, and the two ejector pins 48 are controlled to move toward or oppositely, thereby realizing the lateral spacing adjustment of the two ejector pins 48. Subsequently, the moving block 44 is slid in the adjustment cavity 43 opened at the bottom of the moving platform 42, and the longitudinal spacing of adjacent moving blocks 44 is accurately controlled by the scale line 9. When the moving block 44 moves to the desired position, the fastening nut 49 is rotated, and the fastening nut 49 is screwed into the moving block 44 through the threaded screw connection between the fastening nut 49 and the moving block 44, and the nut of the fastening nut 49 is squeezed on the outer wall of the moving platform 42. The fixing of the position of the fastening nut 49 is achieved through friction resistance, and then the fixing of the position of the moving block 44 is achieved, and the longitudinal interval adjustment of the ejector pin 48 is completed. When the material belt 6 is conveyed, the first cylinder 2 drives the lifting platform 3 to move downward through its output end, and the ejector position adjustment component 4 at the bottom of the lifting platform 3 moves downward synchronously, and the ejector pin 48 is inserted into the pinhole 7 on the material belt 6. The ball screw in the first screw moving component 41 rotates to make the moving platform 42 move laterally, and then the ejector pin 48 moves laterally. The ejector pin 48 conveys the material belt 6 horizontally on the feeding platform 5. After completing the conveying of the material belt 6 for a certain distance, the second cylinder 45 drives the press table 46 to move upward through its output end, and the ejector pin 48 at the bottom of the press table 46 pulls out the pinhole 7 to realize the feeding of the material belt 6. Through the lateral movement of the moving platform 42, multiple press tables 46 move upward one by one to realize continuous feeding of the material belt 6.

[0026] In a further preferred embodiment of the present invention, Figure 2 As shown, the first screw moving assembly 41 and the second screw moving assembly 47 are both composed of a three-phase asynchronous motor and a ball screw.

[0027] In this embodiment, the first screw moving assembly 41 and the second screw moving assembly 47 can be driven to move, so that the moving platform 42 and the ejector pin 48 can move linearly.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, the mounting plate 1, the lifting platform 3 and the feeding platform 5 are all level with each other.

[0029] In this embodiment, the ejector pin 48 can be vertically inserted into the material belt 6, thereby enabling the material belt 6 to be stably transported and fed horizontally.

[0030] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the fastening nut 49 passes through the through slot 491 , and the outer side wall of the fastening nut 49 does not contact the inner side wall of the through slot 491 .

[0031] In this embodiment, the through slot 491 can provide space for the lateral movement of the fastening nut 49 , and the position of the fastening nut 49 can be fixed by squeezing the fastening nut 49 against the outer wall of the moving platform 42 .
