Description

Technical Field

[0001] The utility model relates to the field of lamp bead production, in particular to a loading mechanism for a die bonder. Background Technique

[0002] In the current lighting market, LED lamp beads are highly favored due to their significant advantages such as high efficiency, energy conservation, and environmental protection, and the market demand continues to grow. In the production process of LED lamp beads, the die bonder is one of the key devices. For the loading equipment used in some die bonders, usually, a manipulator sucks the materials from the material tray onto the loading track. However, when facing materials of different sizes, it is difficult for the traditional manipulator to make flexible adjustments, and the adjustment process is very cumbersome, time-consuming, and laborious.

[0003] After retrieval, Chinese Patent Publication No.: CN218560365U discloses a loading mechanism for a die bonder, including: a loading body, the loading body includes a loading table, a material rack is arranged on the outer surface of the loading table, a material groove is opened inside the material rack, a loading track is fixedly connected to the outer surface of the loading table, a support frame is fixedly connected to the side surface of the loading table, a guide rail is fixedly connected to the outer surface of the support frame, and a lead screw nut mechanism is slidably connected to the outer surface of the guide rail; a manipulator, the manipulator includes a suction nozzle, and the suction nozzle is arranged below the side of the lead screw nut mechanism away from the support frame. Through the connection of the screw and the lead screw nut mechanism, when facing materials of different sizes, by rotating the screw, the suction nozzle can slide on the upper surface of the connecting rod, so as to adjust to a suitable suction position, and then the position of the suction nozzle can be fixed by rotating the screw. This device is simple to operate and can greatly save the adjustment time when facing materials of different sizes.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 - Figure 2 , Figure 5 , an embodiment provided by the present invention: a feeding mechanism for a die bonder, including a driving slide rail 1. The driving slide rail 1 is a prior art, and through it, the suction nozzle 33 of the mechanical claw can be driven to move for feeding. And those skilled in the art can implement it. Since it is a prior art, not too much description will be made in this case. The lower surface of the front end of the driving slide rail 1 is in contact with a support plate 2 that ensures the stable movement of the suction nozzle 33. A chute 5 is provided on the upper surface of the support plate 2. Multiple suction nozzles 33 slide on the inner wall of the chute 5 to adjust the position. An assembly and disassembly component is provided on the upper surface of the support plate 2, and an adjustment component is provided on the lower surface of the support plate 2. The adjustment component includes a cylindrical shell 32. The cylindrical shell 32 is fixedly connected to the lower surface of the support plate 2. A cylinder 35 is rotatably connected to the inner wall of the cylindrical shell 32. A guide groove 36 is provided on the outer wall of the cylinder 35. The guide groove 36 has a certain arc to ensure that when the cylinder 35 rotates, the connecting plate 34 can move along the arc. A connecting plate 34 is slidably connected to the inner wall of the guide groove 36. The top end of the connecting plate 34 penetrates and is slidably connected to the lower surface of the cylindrical shell 32. The connecting plate 34 is provided with a cylindrical rod-shaped structure in the middle, and at the same time, it horizontally penetrates and slides left and right on the lower surface of the cylindrical shell 32. Suction nozzles 33 are fixedly connected to both the front surface and the rear surface of the connecting plate 34. The suction nozzle 33 is a prior art, and through it, the product can be fixed. The top end of the suction nozzle 33 is slidably connected to the inner wall of the chute 5. Multiple groups of guide grooves 36 are provided, and the multiple groups of guide grooves 36 are symmetrically arranged with the center line of the cylinder 35 as the axis of symmetry. The multiple groups of guide grooves 36 are provided to ensure that the multiple groups of suction nozzles 33 can move synchronously.

[0033] Refer to Figure 1 , Figure 3 , Figure 5, the disassembly and assembly component includes a support block 41. The support block 41 is adapted to the inner wall at the bottom front side of the driving slide rail 1 to ensure the stability of the limit. The support block 41 is fixedly connected to the upper surface of the support plate 2. A limit groove 46 is formed in the front surface at the top of the support block 41. The support block 41 slides on the inner wall at the bottom front side of the driving slide rail 1. The support block 41 is set in a T shape, and being set in a T shape ensures the stability of the support plate 2.

[0034] Refer to Figure 2 , Figure 4 , the adjustment component further includes a rotating rod 31 that can drive the cylinder 35 to rotate. The rotating rod 31 passes through and is rotatably connected to the left surface of the cylindrical shell 32. The rotating rod 31 passes through and is fixedly connected to the left surface of the cylinder 35. A limiting rod 37 that can limit the rotating rod 31 is slidably connected through the rear end of the left surface of the rotating rod 31. Multiple groups of grooves are formed in the outer wall of the cylindrical shell 32 near the rotating rod 31, and the multiple groups of grooves are the limiting points for the suction nozzle 33 at different positions. The right surface of the limiting rod 37 contacts the inner wall of the groove. A spring 38 is sleeved on the outer wall of the limiting rod 37. The spring 38 always pulls the limiting rod 37 to move to the right through its own elasticity to ensure the stability of the limit of the limiting rod 37. One end of the spring 38 is fixedly connected to the right surface of the limiting rod 37, and the other end of the spring 38 is fixedly connected to the left surface of the rotating rod 31.

[0035] Refer to Figure 3 , Figure 5 , the disassembly and assembly component further includes a moving plate 44 that ensures the stable movement of the limiting plate 45. The moving plate 44 passes through and is slidably connected to the front surface at the bottom front end of the driving slide rail 1. A limiting plate 45 that can limit the support block 41 is fixedly connected to the rear surface of the moving plate 44. The limiting plate 45 is slidably connected to the inner wall at the bottom front side, and the rear surface of the limiting plate 45 contacts the inner wall of the limit groove 46.

[0036] Refer to Figure 1 , Figure 3 , Figure 5 , the disassembly and assembly component further includes a fixing block 42 that ensures the stable rotation of the bidirectional threaded rod 43. The fixing block 42 is fixedly connected to the front surface at the bottom front end of the driving slide rail 1. A bidirectional threaded rod 43 is rotatably connected through the front surface of the fixing block 42. The bidirectional threaded rod 43 is a prior art, and it is a rod-shaped structure with two sets of threads with different helix directions on its outer wall. When rotating, the structures threadedly connected to its outer wall will move relatively or in opposite directions. At the same time, it has the characteristics of self-locking in the front and rear directions to ensure the stability of the structures threadedly connected to its outer wall when not rotating. The bidirectional threaded rod 43 passes through and is threadedly connected to the front surface at the left end of the moving plate 44.

[0037] Working principle: When it is necessary to adjust the spacing of the suction nozzles 33, pull the limit rod 37 outwards so that the limit rod 37 disengages from the groove on the left surface of the cylindrical shell 32, and the spring 38 is stretched. At this time, rotate the rotating rod 31. The rotating rod 31 drives the cylinder 35 to rotate, and the guiding groove 36 on the outer wall of the cylinder 35 rotates accordingly. The connecting plate 34 slidably connected to the inner wall of the guiding groove 36 moves along with the arc of the guiding groove 36, thereby driving the suction nozzles 33 to slide in the sliding groove 5, realizing the adjustment of the spacing of the suction nozzles 33. Multiple groups of guiding grooves 36 are symmetrically arranged with the center line of the cylinder 35 as the axis of symmetry, ensuring that multiple groups of suction nozzles 33 can move evenly, guaranteeing the uniformity of the spacing between the suction nozzles 33, improving the stability of fixing the product. After adjusting to the appropriate position, release the limit rod 37, the spring 38 contracts, and pull the limit rod 37 to insert it back into the groove on the left surface of the cylindrical shell 32 to limit the rotating rod 31 and fix the position of the suction nozzles 33.

[0038] When it is necessary to disassemble and assemble the suction nozzles 33, rotate the bidirectional threaded rod 43. Since the bidirectional threaded rod 43 has the characteristic of self-locking in the front and rear directions and two groups of threads with different helix directions are provided on its outer wall, when the bidirectional threaded rod 43 is rotated, the moving plate 44 threadedly connected to its outer wall will perform a linear movement. The moving plate 44 drives the limit plate 45 to move, so that the rear surface of the limit plate 45 disengages from or contacts the limit groove 46 on the front surface of the top end of the support block 41, thereby realizing the disassembly and assembly of the suction nozzles 33. The entire disassembly and assembly process does not require using tools to rotate multiple bolts, is easy to operate, has high efficiency, and can be completed by one person. When installing, insert the support block 41 into the inner wall of the front bottom side of the driving slide rail 1, and then rotate the bidirectional threaded rod 43 in the reverse direction. The subsequent structural cooperation method is the same as above.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
