Description

Technical Field

[0001] The utility model relates to the technical field of SMT patch technology, in particular to an SMT board pushing machine. Background Art

[0002] SMT PCB ejectors are a type of equipment used in SMT (Surface Mount Technology) production lines in the electronics manufacturing industry. They are primarily used for automatic board delivery and collection. The design and functionality of these machines help improve production efficiency while ensuring safe and precise handling of PCBs (Printed Circuit Boards).

[0003] In industrial production, to improve work efficiency, circuit boards need to be collected and reprocessed. Therefore, an SMT pusher is needed to transport and collect the patches. For example, the prior art Chinese Patent Publication No. "CN220173705U" discloses an SMT pusher, which includes a pusher body, a cylinder box disposed on the outer surface of the pusher body, a telescopic rod disposed inside the cylinder box, a push plate fixedly connected to one end of the telescopic rod, and a working plate disposed on the outer surface of the push plate. The utility model has the following advantages and effects: SMT boards can be pushed out of the pusher body and pushed into a collection box for collection. The provision of a first conveyor bed facilitates the transfer of the collection box to the outside of the pusher. The provision of a support plate limits the height of the second conveyor bed. The provision of a bridge allows the pusher body to raise the height of the collection box during operation, facilitating the complete filling of the collection box with SMT boards. The collection box is simultaneously raised to the height of the second conveyor bed, facilitating the collection of the filled collection box by the staff for subsequent processing.

[0004] However, in actual operation, the patch is pushed by reciprocatingly driving the push plate, and each reciprocating movement can only push one patch. The transmission efficiency of pushing the patch is low, which affects the processing efficiency of the patch. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the pusher can only push one patch in one reciprocating movement and the board feeding efficiency is low, and to propose an SMT pusher.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An SMT pusher is designed, comprising a frame, with a lifting device and a conveying platform provided on the side of the frame. The lifting device is used to lift and lower a transport frame for collecting patches, and the conveying platform comprises a conveying table, which pushes patches to the transport frame through a pusher mechanism.

[0008] The push plate mechanism includes a guide plate and a pair of fixed seats. The guide plates are provided in pair, and a spacing adjustment component is provided between the guide plates and the conveying platform. The push plate is detachably connected to the fixed seat.

[0009] Furthermore, the spacing adjustment component includes a guide groove, and a material port is provided on both sides of the conveying platform. The two sides below the material port penetrate to form the guide groove, and the two ends of the guide plate are slidably connected to the guide groove through a guide part, and the guide parts on both sides are provided on the opposite sides of a pair of guide plates.

[0010] Furthermore, it also includes a bidirectional screw rod, a pair of guide plates are L-shaped structures, and the top sides thereof are provided with upward extending baffles, the bidirectional screw rod is rotatably connected to the bottom of the conveying platform, and one end thereof is extended and fixed with a handwheel, and the bottom of the pair of guide plates are respectively threadedly connected to the two ends of the bidirectional screw rod.

[0011] Furthermore, the push plate mechanism also includes a bracket and a synchronous belt. The bracket is fixed in the conveying platform, and a pair of guide rods are provided on the bracket. The bracket is rotatably connected to the synchronous belt through a driving assembly. The fixed seat is slidably connected to the guide rod, and the positions therebetween are relatively arranged and are both fixed to the side of the synchronous belt.

[0012] Furthermore, the fixing seat is L-shaped and provided with a through slot, the push plate is tilted and matches the height of the patch, and the bottom thereof is rotatably connected to a rotating seat;

[0013] The rotating seat is in a T-shaped structure and engages with the through slot, and at least one positioning glass bead is embedded at the bottom, and the positioning glass bead abuts against the fixing seat.

[0014] Furthermore, a torsion spring is fixedly connected between the rotating shaft of the push plate and the rotating seat, and the push plate rotates when it is impacted by the patch delivered from the far end.

[0015] The utility model proposes an SMT plate pushing machine, which has the following beneficial effects: the utility model drives the push plates on both sides to move back and forth by driving the synchronous belt, and the push plates can push two patches with one reciprocating movement. In addition, the push plates are rotatably connected to the rotating seat through a torsion spring, which can push the patches while avoiding the occurrence of patch jamming. In addition, the spacing between the guide plates on both sides can be adjusted by a bidirectional screw rod to adapt to patches of different widths, thereby improving the practicality of the device, effectively improving the conveying efficiency and processing efficiency of the patches, and having a simple structure, easy operation and strong practicality.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 An SMT push board machine includes a frame 1, a lifting device 2 and a conveying platform 3 are provided on the side of the frame 1, the lifting device 2 is used to lift and lower the transport frame 21 for collecting patches, the conveying platform 3 includes a conveying table 31, and the conveying table 31 pushes the patches to the transport frame 21 through a push board mechanism 4;

[0023] The push plate mechanism 4 includes a guide plate 41 and a pair of fixed seats 42 . The guide plates 41 are provided in pair, and a spacing adjustment component 5 is provided between the guide plates 41 and the conveying platform 31 . A push plate 6 is detachably connected to the fixed seat 42 .

[0024] It should be added that the conveying platform 3 is used in conjunction with an external feeding device, that is, the patch is conveyed to the conveying platform 31 by the feeding device (such as a suction cup adsorption feeding device), and then the patch is pushed into the transport frame 21 by the pushing plate mechanism 4;

[0025] In addition, when the patch is pushed by the push plate mechanism 4, the transport frame 21 is gradually raised following the feeding rhythm under the drive of the lifting device to cooperate with the push plate 6 to deliver the patch.

[0026] Furthermore, the spacing adjustment component 5 includes a guide groove 51, and a material port is provided on both sides of the conveying platform 31. The two sides below the material port penetrate to form the guide groove 51, and the two ends of the guide plate 41 are slidably connected to the guide groove 51 through a guide portion 52, and the guide portions 52 on both sides are provided on the opposite sides of a pair of guide plates 41.

[0027] Furthermore, it also includes a bidirectional screw rod 53, a pair of guide plates 41 are L-shaped structures, and the top sides thereof are provided with upward extending baffles, the bidirectional screw rod 53 is rotatably connected to the bottom of the conveying platform 31, and one end thereof is extended and fixed with a handwheel 54, and the bottom of a pair of guide plates 41 are respectively threadedly connected to the two ends of the bidirectional screw rod 53.

[0028] It is worth mentioning that a slide groove is formed between the baffles on both sides, and the patch is arranged in the slide groove for limited sliding. Of course, in order to protect the patch from damage, the top of the guide plate 41 can be rotatably connected to a number of rollers, among which the spacing can be adjusted to adapt to patches of different widths and increase the scope of application.

[0029] In more detail, the push plate mechanism 4 also includes a bracket 43 and a synchronous belt 44. The bracket 43 is fixed in the conveying platform 31, and a pair of guide rods 45 are provided on the bracket 43. The bracket 43 is rotatably connected to the synchronous belt 44 through a driving assembly. The fixed seat 42 is slidably connected to the guide rod 45, and the positions therebetween are relatively arranged and are both fixed to the side of the synchronous belt 44.

[0030] It should be noted that the bracket 43 is arranged above the bidirectional screw 53, and the driving assembly includes a pair of synchronous wheels and a motor. The top of the bracket 43 is rotatably connected to a pair of synchronous wheels, and the bottom is fixed with a motor. The shaft end of the motor is fixedly connected to one of the synchronous wheels, and the synchronous belt 44 is sleeved between the pair of synchronous wheels.

[0031] In general, the fixing seat 42 is L-shaped and has a through slot 421. The push plate 6 is tilted and matches the height of the patch, and its bottom is rotatably connected to a rotating seat 61.

[0032] The rotating seat 61 is in a T-shaped structure and engages with the through slot 421 , and has at least one positioning bead 62 embedded at the bottom. The positioning bead 62 abuts against the fixing seat 42 .

[0033] Specifically, the positioning glass bead 62 facilitates quick disassembly and assembly of the rotating seat 61 to achieve the function of replacing the push plate 6, thereby preventing the torsion spring from aging or the push plate 6 from being inconvenient to replace due to damage.

[0034] Finally, a torsion spring is fixedly connected between the rotating shaft of the push plate 6 and the rotating seat 61, and the push plate 6 rotates when it is resisted by the patch delivered from the far end.

[0035] Of course, the rotating seat 61 needs to limit the rotation angle of the push plate 6 to ensure that the height of the push plate 6 under normal circumstances matches the conveying height of the patch.

[0036] Working mode; when working, the patch is transported by the feeding device 21 to the transport frame, and then the spacing between the guide plates 41 on both sides is adjusted according to the width of the patch;

[0037] By rotating the bidirectional screw rod 53 by the hand wheel 54, the guide plates 41 on both sides are driven to move relative to each other to adjust the spacing. The patch is limited and slides between a pair of baffles. When it hits the push plate 6, the push plate 6 rotates and returns to its original position under the action of the torsion spring after it separates from the patch.

[0038] The motor drives the synchronous belt 44 to rotate, and the synchronous belt 44 drives the push plates 6 on both sides to move back and forth relative to each other, pushing the patches one by one.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
