Description

Technical Field

[0001] This utility model belongs to the technical field of SMT placement equipment, and in particular relates to a copper buckle riveting mechanism and an SMT material tape receiving machine. Background Technology

[0002] A pick-and-place machine is a device that accurately places surface mount components onto PCB pads by moving the placement head. During production, when the tape in the pick-and-place machine is about to run out, a tape splicer is needed to connect the head of the new tape in the storage cartridge to the tail of the old tape in the pick-and-place machine. The tape splicer usually uses adhesive tape to join the head of the new tape to the tail of the old tape. This splicing method has weak bonding strength and is prone to causing the head of the new tape to detach from the tail of the old tape, affecting the normal operation of the pick-and-place machine.

[0003] Therefore, the designers proposed using copper clips to connect the new material strip head to the old material strip tail, thus connecting the upper film of the new and old material strips and facilitating continuous collection after the upper film is peeled off. However, most existing copper clips are joined manually by riveting, which obviously suffers from high labor intensity and low joining efficiency. Utility Model Content

[0020] Please see Figures 1 to 5As shown, in this embodiment, a copper buckle riveting mechanism includes a material receiving component 10, a first support platform 20, a second support platform 30, and a lifting component 40. The first support platform 20 is configured to receive and support the new material strip head 21 and the old material strip tail 22 to be joined. The second support platform 30 is located on one side of the first support platform 20 and is configured to receive and support a copper buckle 50. The copper buckle 50 is located below the new material strip head 21 and the old material strip tail 22. The copper buckle 50 has multiple riveting portions 51, each riveting portion 51 corresponding to a material hole 23 of a new material strip head 21 or an old material strip tail 22. The lifting component 40 is located below the second support platform 30. The lifting component 40 is configured to lift all the riveted parts 51 on the copper buckle 50 upward and extend them out of the corresponding material holes 23. The material taking component 10 includes a first driving component 11 and an adsorption component 12. The driving end of the first driving component 11 is connected to the adsorption component 12. The first driving component 11 is configured to drive the adsorption component 12 to move horizontally and move vertically. The adsorption component 12 is configured to adsorb or release a copper buckle 50. The adsorption component 12 is also configured to cooperate with the lifting component 40 to rivet the copper buckle 50 located on the second support platform 30 at the connection between the new material belt head 21 and the old material belt tail 22.

[0021] As can be seen, through the cooperation of the material picking component 10, the first support platform 20, the second support platform 30 and the lifting component 40, the first support platform 20 receives and carries the new material strip head 21 and the old material strip tail 22 to be joined. The first drive component 11 drives the adsorption component 12 to move horizontally and rise and fall. With the help of the adsorption component 12, a copper buckle 50 is released to the second support platform 30. The lifting component 40 lifts all the riveting parts 51 on the copper buckle 50 upward and extends them out of the corresponding material holes 23. The adsorption component 12 cooperates with the lifting component 40 to rivet the copper buckle 50 located on the second support platform 30 to join the connection between the new material strip head 21 and the old material strip tail 22, which replaces manual riveting and greatly improves the joining efficiency.

[0022] In one embodiment, the riveting part 51 includes at least one foldable flange, and the lifting assembly 40 lifts all the flanges on the copper buckle 50 upward so that each flange protrudes from the corresponding feed hole 23.

[0023] As can be seen, by setting an upward-folding flange at the riveting part 51, the lifting component 40 lifts all the flanges on the copper buckle 50 upward, so that each flange extends out of the corresponding material hole 23, which further improves the stability of riveting.

[0024] In one embodiment, the adsorption component 12 includes an adsorption head 120 and a riveting head 121. The adsorption surface of the adsorption head 120 is provided with a plurality of adsorption holes 120a. An air extraction channel is provided inside the adsorption head 120. The first end of the air extraction channel is connected to the adsorption hole 120a, and the second end of the air extraction channel is connected to an air extraction component. The air extraction component is configured to extract air from the air extraction channel so as to adsorb the copper buckle 50 onto the adsorption surface of the adsorption head 120 through the plurality of adsorption holes 120a. The riveting head 121 is disposed on one side of the adsorption head 120. When riveting the copper buckle 50, the riveting head 121 presses down the flange protruding from the material hole 23, so that the flange folds outward and presses against the edge of the material hole 23.

[0025] In one embodiment, the bottom of the riveting head 121 is provided with a plurality of downwardly extending protrusions 121b, each protrusion 121b corresponding to a riveting part 51; when riveting the copper buckle 50, each protrusion 121b presses down the flange of the corresponding protruding material hole 23.

[0026] As can be seen, by opening multiple adsorption holes 120a on the adsorption surface of the adsorption head 120 and connecting it to the air extraction component through the air extraction channel, the copper buckle 50 is firmly adsorbed onto the adsorption surface using the principle of negative pressure, resulting in high adsorption stability. At the same time, a protrusion 121b is provided at the bottom of the riveting head 121, which facilitates the riveting of the flange of the corresponding riveting part 51 into the material hole 23 during riveting, thus providing an adsorption component 12 with high adsorption stability and good riveting effect.

[0027] Specifically, the copper buckle 50 has four rivet parts 51 spaced apart along its own length direction, and four protrusions 121b are provided, with each protrusion 121b corresponding to one rivet part 51.

[0028] It can be seen that by setting four riveting parts 51 on the copper buckle 50, the riveting firmness is further improved.

[0029] In one embodiment, the lifting assembly 40 includes a lifting base 41, a lifting drive 42, and a lifting member 43. The lifting base 41 is mounted on one side of the first support platform 20. The lifting member 43 is vertically and elliptically disposed within the lifting base 41. Multiple top pins 44 extend upward from the top of the lifting member 43, each top pin 44 corresponding to a riveting part 51. The second support platform 30 has multiple clearance holes 31 for avoiding the top pins 44. The fixed end of the lifting drive 42 is mounted on the lifting base 41. The drive end of component 42 is connected to the lifting component 43. The lifting drive component 42 is configured to drive the lifting component 43 to rise and fall, thereby driving multiple top pins 44 to rise to a high position or a low position in the corresponding clearance hole 31. When the top pin 44 is in the high position, each top pin 44 passes through the corresponding clearance hole 31 and abuts against the corresponding riveting part 51, thereby pushing the copper buckle 50 located on the second support platform 30 away from the support surface of the second support platform 30, thereby causing all the riveting parts 51 on the copper buckle 50 to be pushed upward and protrude from the corresponding material hole 23.

[0030] Specifically, the lifting drive component 42 is a lifting cylinder, a motor, or a drive module with linear stroke.

[0031] As can be seen, by setting multiple top pins 44 at the top of the lifting component 43, with each top pin 44 corresponding to a riveting part 51 of the copper buckle 50, and by opening clearance holes 31 in the second support platform 30 for the top pins 44 to pass through for the pins, it is ensured that the pins accurately abut against the corresponding riveting parts 51, thus preventing the copper buckle 50 from shifting or tilting during the lifting process. This provides a lifting component 40 with high lifting accuracy and good lifting effect.

[0032] In one embodiment, the lifting assembly 40 also includes a plurality of buffer springs 45, each buffer spring 45 corresponding to a top pin 44, and the buffer spring 45 is installed between the corresponding top pin 44 and the lifting member 43.

[0033] It can be seen that by setting the buffer spring 45, when the top pin 44 is in the high position, the lifting part 43 is prevented from making hard contact with the bottom of the second support platform 30, thereby improving the service life of the lifting part 43 and the second support platform 30.

[0034] In one embodiment, the first driving assembly 11 includes a base 110, a first driving member 111, a transverse plate 112, a second driving member 113, and a lifting plate 114, wherein: the transverse plate 112 is reciprocally movable on the base 110 in the horizontal direction; the fixed end of the first driving member 111 is mounted on the base 110, and the driving end of the first driving member 111 is connected to the transverse plate 112; the first driving member 111 is configured to drive the transverse plate 112 to reciprocate in the horizontal direction; the lifting plate 114 is vertically movable on the transverse plate 112; the adsorption member 12 is mounted on the lifting plate 114; the fixed end of the second driving member 113 is mounted on the transverse plate 112, and the driving end of the second driving member 113 is connected to the lifting plate 114; the second driving member 113 is configured to drive the lifting plate 114 to rise and fall, thereby causing the adsorption member 12 to rise and fall relative to the transverse plate 112.

[0035] Specifically, both the first driving component 111 and the second driving component 113 are driven motors.

[0036] Of course, the first drive unit 111 and the second drive unit 113 can also be cylinders or drive modules with linear stroke.

[0037] In one embodiment, a sliding guide pair is provided between the transverse plate 112 and the base 110. The sliding guide pair includes a linear guide rail 13 and a slider 14. The linear guide rail 13 is fixed to the base 110 extending horizontally, and the slider 14 is fixed to the transverse plate 112 and slidably sleeved on the linear guide rail 13.

[0038] As can be seen, by setting the linear guide rail 13 and the slider 14, the sliding guide of the transverse plate 112 on the base 110 is realized, providing a sliding guide pair with high guiding accuracy and good guiding effect.

[0039] In one embodiment, a transmission pair is provided between the second driving member 113 and the lifting plate 114. The transmission pair includes a transmission screw 15 and a nut 16. The transmission screw 15 is rotatably mounted on the transverse plate 112 along its own axis. The nut 16 is fixed on the lifting plate 114 and sleeved on the transmission screw 15. The driving end of the second driving member 113 is connected to the transmission screw 15. The second driving member 113 is configured to drive the transmission screw 15 to rotate along its own axis. The second driving member 113 drives the lifting plate 114 to rise and fall through the cooperation of the transmission screw 15 and the nut 16.

[0040] As can be seen, through the cooperation of the transmission screw 15 and the nut 16, the second driving component 113 drives the transmission screw 15 to rotate along its own axis, effectively driving the lifting plate 114 to rise and fall, providing a transmission pair with high transmission accuracy and high transmission efficiency.

[0041] During the riveting process, the above-mentioned copper buckle riveting mechanism works as follows: First, a person or a robot places the new material strip head 21 and the old material strip tail 22 to be joined on the first support platform 20. Second, the first drive assembly 11 drives the adsorption member 12 to move laterally and rise and fall, and the adsorption member 12 adsorbs or releases a copper buckle 50 onto the second support platform 30. Then, the lifting drive member 42 drives the lifting member 43 to rise, which drives multiple top pins 44 to rise to a high position in the corresponding clearance holes 31. Each top pin 44 passes through the corresponding clearance hole 31 and abuts against the corresponding riveting part 51, pushing the copper buckle 50 on the second support platform 30 away from the support surface of the second support platform 30, thereby causing all the riveting parts 51 on the copper buckle 50 to be pushed upward and protrude from the corresponding material hole 23. Finally, the first drive assembly 11 drives the adsorption member 12 to descend, and each protrusion 121b rivets the flange of the corresponding riveting part 51 into the material hole 23, completing the riveting.

[0042] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
