Description

Technical Field

[0001] The invention relates to the technical field of riveting machines, in particular to a riveting machine used for electronic radiators. Background Art

[0002] Electronic radiators are usually used to dissipate heat for high-power electronic components. The electronic radiator includes a base and a plurality of heat sinks arranged on the base. The plurality of heat sinks are arranged parallel to each other and at intervals on the base. The heat on the electronic components can be transferred to the heat sinks, and heat exchange with the outside world is carried out through the heat sink, so as to achieve the purpose of dissipating heat for the electronic components. When the electronic radiator is produced, a socket will be set between the two heat sinks of the electronic radiator, and the rivets will be pressed into the socket for assembly.

[0003] At present, a swing arm is often designed and used in combination with a pressure head. When the riveting operation is not carried out, the rivet can be positioned with the help of the swing arm, which is convenient for the subsequent riveting operation and ensures that the rivet will not be displaced due to the driving effect of the conveyor belt. This reflects the flexibility of the overall design and can also ensure the smooth progress of the entire riveting operation. However, it has the following defects: the spring is prone to elastic fatigue after long-term operation, causing its elasticity to change. The spring that has elastic fatigue is prone to cause the swing arm to not move into place when the pressure head descends, thereby hindering the descent of the pressure head. At the same time, the failure of the swing arm to move into place will also affect the positioning of the rivet.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a riveting machine for electronic heat sink is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a riveting machine for an electronic radiator, which solves the problems raised in the above-mentioned background technology.

[0007] Furthermore, one end of the transmission steel wire rope is fixedly connected to the outer surface of the riveting pressure head, and the other end of the transmission steel wire rope is fixedly connected to the side surface of the transmission plate.

[0008] Furthermore, the upper surface of the gradually inclined spiral member is a spiral plane structure, and the bottom of the gravity slide is located between the head and tail ends of the gradually inclined spiral member.

[0009] Furthermore, the side surface of the protruding portion at the bottom of the gravity slide is in an inclined structure, and the gravity slide forms a transmission structure through the gradually inclined spiral member and the torsion spring shaft.

[0010] Furthermore, a support plate is provided below the conveyor belt, and the support plate is located directly below the riveting head.

[0011] Furthermore, the surface of the conveyor belt is equidistantly distributed with feed components, and the feed components include a feed plate and a limiting groove, and a limiting groove is provided in the middle of the surface of the feed plate.

[0016] The present invention provides a riveting machine for electronic radiators, which has the following beneficial effects:

[0017] The riveting machine for electronic radiators has a riveting head that rises after a riveting operation is completed. During the rising process, the torsion spring shaft is reset to drive the round head end of the receiving slideway back to the bottom of the riveting head to receive the useless part of the fallen rivet, and arrange it to a designated position for collection. Even if elastic fatigue occurs during the resetting process of the torsion spring shaft and the resetting is not in place, the inclined surface of the protruding part of the bottom of the gravity slide will push the gradually inclined spiral part to rotate and reset in place during the process of the gravity slide descending under the action of gravity, so that the round head end of the receiving slideway and the positioning arc piece can be reset to the bottom of the riveting head, thereby avoiding the round head end of the receiving slideway from being reset in place and failing to accurately receive the useless part of the fallen rivet, and also avoiding the positioning arc piece from being reset in place and failing to accurately position the rivet in transmission to the bottom of the riveting head.

[0026] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] like Figure 1-Figure 7As shown, the present invention provides a technical solution: a riveting machine for electronic radiators, comprising a riveting assembly 1 and a conveyor belt 2, the riveting assembly 1 comprising a support frame 101, a hydraulic push rod 102, a riveting pressure head 103, a wire pipe 104, a transmission wire rope 105, a torsion spring shaft 106, a transmission plate 107, a receiving slide 108, a gradually inclined spiral member 109, a limiting guide rail 110 and a gravity slide 111, a hydraulic push rod 102 is fixed to the upper side of the support frame 101, and the bottom of the hydraulic push rod 102 is connected to the riveting pressure head 103, a wire pipe 104 is arranged on one side of the riveting pressure head 103, and the wire pipe 104 is penetrated with a transmission wire rope 105, a torsion spring shaft 106 is arranged on the bottom surface of the support frame 101, and the top of the torsion spring shaft 106 is connected to the transmission plate 107, and the transmission plate 10 A receiving slide 108 is fixed on the surface of 7, a gradually inclined spiral 109 is fixed on the outer wall of the torsion spring shaft 106, a limiting guide rail 110 is fixed on one side of the torsion spring shaft 106 on the surface of the support frame 101, and a gravity slide 111 is slidably connected inside the limiting guide rail 110, and the transmission belt 2 is arranged below the receiving slide 108, one end of the transmission wire rope 105 is fixedly connected to the outer surface of the riveting pressure head 103, and the other end of the transmission wire rope 105 is fixedly connected to the side of the transmission plate 107, the upper surface of the gradually inclined spiral 109 is a spiral plane structure, and the bottom of the gravity slide 111 is located between the head and tail ends of the gradually inclined spiral 109, the side of the protruding part of the bottom of the gravity slide 111 is an inclined structure, and the gravity slide 111 forms a transmission structure with the torsion spring shaft 106 through the gradually inclined spiral 109;

[0028] The specific operation is as follows: when performing the riveting operation, the hydraulic push rod 102 extends to make the riveting pressure head 103 drop vertically. During the descent of the riveting pressure head 103, the transmission wire rope 105 applies tension to the side of the transmission plate 107. Under the action of the tension, the transmission plate 107 rotates with the torsion spring shaft 106 as the center of the circle, so that the round head end of the receiving slideway 108 and the positioning arc piece 112 leave the bottom of the riveting pressure head 103. The torsion spring shaft 106 rotates under the force and drives the gradually inclined spiral member 109 to rotate. During the rotation of the gradually inclined spiral member 109, a force is applied along the inclined surface of the protruding part of the bottom of the gravity slide 111, so that the gravity slide 111 is forced to slide up along the inside of the limiting guide rail 110;

[0029] After the round head end of the receiving slide 108 is misaligned with the riveting press 103 due to rotation, the riveting press 103 continues to descend. When the rivet 404 enters the riveting press 103 for pressing, the useless part of the riveting press 103 carrying the rivet 404 rises after the riveting is completed. When the riveting press 103 rises back to its original position, the transmission plate 107 rotates and resets under the reset action of the torsion spring shaft 106, so that the round head end of the receiving slide 108 returns to the bottom of the riveting press 103 again. At this time, the riveting press 103 spits out the useless part of the rivet 404 inside it, and the useless part of the rivet 404 falls onto the receiving slide 108 and slides along its inclined surface to be discharged to the specified position;

[0030] When the torsion spring shaft 106 is reset, the gradually inclined spiral member 109 rotates and resets accordingly. At this time, the gravity slide 111 slides down along the inner part of the limiting guide rail 110 under the action of gravity. At this time, even if the torsion spring shaft 106 produces elastic fatigue and fails to reset, the inclined surface of the protruding part of the bottom of the gravity slide 111 will push the gradually inclined spiral member 109 to rotate and reset in place during the descent of the gravity slide 111, so that the round head end of the receiving slide 108 and the positioning arc piece 112 can be reset to the right below the riveting pressure head 103. The lifting and lowering of the gravity slide 111 will cause friction with the gradually inclined spiral member 109. By embedding active balls on any surface of the two, the sliding friction can be converted into rolling friction to reduce the friction force, thereby avoiding friction damage. Lubrication can also be used to enhance the lubricity to reduce the friction force.

[0031] Based on the above description, the riveting press head 103 of the present invention rises after completing a riveting operation. During the rising process, the torsion spring shaft 106 is reset to drive the round head end of the receiving slide 108 back to the bottom of the riveting press head 103 to receive the useless part of the fallen rivet 404 and arrange it to a designated position for collection. Even if elastic fatigue occurs during the resetting process of the torsion spring shaft 106 and the resetting is not in place, the inclined surface of the protruding part of the bottom of the gravity slide 111 will push the gradually inclined spiral member 109 to rotate and reset in place during the process of the gravity slide 111 descending under the action of gravity, so that the round head end of the receiving slide 108 and the positioning arc piece 112 can be reset to the bottom of the riveting press head 103, thereby avoiding the round head end of the receiving slide 108 from failing to reset and failing to accurately receive the useless part of the fallen rivet 404, and also avoiding the positioning arc piece 112 from failing to reset and failing to accurately position the rivet 404 in transmission to the bottom of the riveting press head 103.

[0032] like Figure 1-Figure 7As shown, a support sheet 3 is provided below the conveyor belt 2, and the support sheet 3 is located directly below the riveting pressure head 103. Feeding components 4 are evenly distributed on the surface of the conveyor belt 2. The feeding components 4 include a material placement plate 401 and a limiting groove 402. The limiting groove 402 is provided in the middle of the surface of the material placement plate 401. The feeding component 4 also includes a heat sink 403 and a rivet 404. The heat sink 403 is placed inside the limiting groove 402, and the surface holes of the heat sink 403 are pierced inside after being stacked. A rivet 404 is provided, and the rivet 404 is located on the central axis of the conveyor belt 2, and the central axis of the conveyor belt 2 is located directly below the riveting head 103. The riveting assembly 1 also includes a positioning arc piece 112, and the bottom surface of the end of the receiving slideway 108 is fixed with a positioning arc piece 112, and the positioning arc piece 112 is located directly below the riveting head 103, and the positioning arc piece 112 is perpendicular to the surface of the conveyor belt 2, and the bottom side of the positioning arc piece 112 is in contact with the outer surface of the rivet 404;

[0033] The specific operation is as follows: the heat sink 403 is stacked and placed in the limiting groove 402 on the surface of the material loading plate 401. At this time, the rivet 404 passes through the hole on the heat sink 403, and the top of the rivet 404 protrudes from the surface of the material loading plate 401. The rivet 404 is transmitted along the conveyor belt 2. When the material loading plate 401 reaches the position of the support plate 3, it enters the riveting operation area. At this time, the positioning arc piece 112 is located directly below the riveting press 103, so that the outer side surface of the rivet 404 being transmitted will be in contact with the bottom side surface of the positioning arc piece 112, which means that the rivet 404 has reached the designated operating position. At this time, the conveyor belt 2 pauses transmission and the riveting press 103 descends. When the riveting press 103 descends, the positioning arc piece 112 rotates away from the rivet 404 due to the tension applied by the transmission wire rope 105, so that the rivet 404 can enter the riveting press 103 for pressing.

[0034] In summary, when the riveting machine for electronic radiators is used, first, the heat sinks 403 are stacked and placed in the limiting grooves 402 on the surface of the material placing plate 401, wherein the heat sinks 403 are stacked on each other and the spacing between the heat sinks 403 is limited by inserts, and the shape of the heat sink 403 is not limited, and is usually round or square, and the limiting grooves 402 are adapted to the shape of the heat sink 403. At this time, the rivet 404 passes through the hole on the heat sink 403, and the top of the rivet 404 protrudes from the surface of the material placing plate 401, and the rivet 404 is transported with the conveyor belt 2. When the material placing plate 401 reaches the position of the support plate 3, it enters the riveting operation area. At this time, the positioning arc piece 112 is located directly below the riveting press head 103, so that the outer side surface of the rivet 404 being transported will fit and contact with the bottom side surface of the positioning arc piece 112, which means that the rivet 404 has reached the specified operation position. At this time, the conveyor belt 2 stops transmitting and the riveting press head 103 descends;

[0035] The hydraulic push rod 102 extends to make the riveting ram 103 descend vertically. During the descent of the riveting ram 103, the transmission wire rope 105 applies tension to the side of the transmission plate 107. Under the action of the tension, the transmission plate 107 rotates with the torsion spring shaft 106 as the center of the circle, so that the round head end of the receiving slideway 108 and the positioning arc piece 112 leave the bottom of the riveting ram 103. The torsion spring shaft 106 rotates under the force and drives the gradually inclined spiral member 109 to rotate. During the rotation of the gradually inclined spiral member 109, a force is applied along the inclined surface of the protruding part of the bottom of the gravity slide 111, so that the gravity slide 111 is forced to slide up along the inside of the limit guide rail 110;

[0036] After the round head end of the receiving slide 108 is misaligned with the riveting press 103 due to rotation, the riveting press 103 continues to descend. When the rivet 404 enters the riveting press 103 for pressing, the useless part of the riveting press 103 carrying the rivet 404 rises after the riveting is completed. When the riveting press 103 rises back to its original position, the transmission plate 107 rotates and resets under the reset action of the torsion spring shaft 106, so that the round head end of the receiving slide 108 returns to the bottom of the riveting press 103 again. At this time, the riveting press 103 spits out the useless part of the rivet 404 inside it, and the useless part of the rivet 404 falls onto the receiving slide 108 and slides along its inclined surface to be discharged to the specified position;

[0037] When the torsion spring shaft 106 is reset, the gradually inclined spiral member 109 rotates and resets accordingly. At this time, the gravity slide 111 slides down along the inner side of the limiting guide rail 110 under the action of gravity. At this time, even if the torsion spring shaft 106 produces elastic fatigue and fails to reset into place, the inclined surface of the protruding part at the bottom of the gravity slide 111 will push the gradually inclined spiral member 109 to rotate and reset into place during the descending process of the gravity slide 111, so that the round head end of the receiving slide 108 and the positioning arc piece 112 can be reset to just below the riveting press head 103, thereby positioning and pressing the subsequent rivet 404.

[0038] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
