[0032] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0034] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0035] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0036] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] In order to solve the problem that when the existing carrier tape splicing device places the carrier tape on the carrier tape flow channel, the carrier tape often warps in the vertical direction and swings in the horizontal direction, resulting in a low success rate for the carrier tape to enter the carrier tape flow channel, thereby affecting the efficiency of subsequent carrier tape splicing. Figures 1 to 6As shown, the carrier tape splicing device specifically includes: a carrier tape feeding mechanism 10, a carrier tape limiting mechanism 20, and a carrier tape flow channel 30, which are arranged in sequence along a first direction; and a transfer mechanism for transporting the carrier tape. The carrier tape is transported along the first direction. The carrier tape limiting mechanism 20, the carrier tape flow channel 30, and the transfer mechanism are all arranged on the mounting base 1. The carrier tape limiting mechanism 20 includes a first limiting component for limiting the carrier tape in the second direction and a second limiting component for limiting the carrier tape in the third direction. The second direction and the third direction are arranged orthogonally. The first direction is perpendicular to both the second direction and the third direction. The transfer mechanism is configured to transport the carrier tape at the carrier tape feeding mechanism 10 to the first limiting component for limiting the second direction, transport the carrier tape at the first limiting component to the second limiting component for limiting the third direction, and transport the carrier tape at the second limiting component into the carrier tape flow channel 30. The utility model limits the carrier tape by the first limiting component and the second limiting component and cooperates with the transfer mechanism to transport the carrier tape to ensure that the carrier tape can accurately enter the carrier tape flow channel 30. It should be noted that, referring to Figure 1 As shown, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction.

[0038] In the above embodiment, the structure of the first limiting assembly includes a support member 21 arranged along a first direction, a lifting member 22 for driving the support member 21 to move along a third direction, and a first limiting plate 23 disposed on the support member 21 and movable along a second direction. The support member 21 is used to support the carrier tape transported by the transfer mechanism. Support wheels 211 are also provided on one side of the support member 21 to cooperate with the support member 21 to support the carrier tape. A lifting cylinder is provided below the support member 21 to drive the support member 21 up and down, thereby enabling the transfer mechanism to avoid the transfer mechanism transporting the carrier tape. Under the action of an external force, the first limiting plate 23 can approach the carrier tape on the support member 21 along the second direction to limit the position of the carrier tape in the second direction and ensure the horizontality of the carrier tape. A spring is provided on the support member 21 to cooperate with the first limiting plate 23. When the external force is no longer acting on the first limiting plate 23, the first limiting plate 23 can automatically return to its original position under the action of the restoring force of the spring.

[0039] In a specific embodiment, the second limiting assembly includes a carrier plate 24 configured at the end of the carrier flow channel 30, where the end of the carrier flow channel 30 refers to the end of the carrier flow channel 30 close to the carrier limiting mechanism 20, a second limiting plate 25 that can move along a third direction relative to the carrier plate 24, a first driving member 26 for driving the second limiting plate 25 to reciprocate along the third direction, and the first driving member 26 can specifically be a driving cylinder arranged along the third direction for the driving rod; and a sensor arranged at the end of the carrier flow channel 30, which is used to sense whether the carrier reaches below the second limiting plate 25 to determine whether the second limiting plate 25 moves downward to limit. The upper surface of the carrier plate 24 is provided with a first groove 28 extending along a first direction; the lower surface of the second limiting plate 25 is provided with a second groove 29 extending along the first direction. When the second limiting plate 25 is overlying the carrier plate 24, the first groove 28 and the second groove 29 form a trumpet-shaped limiting channel to limit the vertical position of the carrier tape, ensuring that the carrier tape does not warp before entering the carrier tape flow channel 30. It will be understood that the opening of the limiting channel near the carrier tape flow channel 30 is smaller than the opening away from the carrier tape flow channel 30, to facilitate the entry and limiting of the leading end of the carrier tape.

[0040] In one embodiment, the transfer mechanism includes a moving assembly and a gripping member 43 disposed on the moving portion of the moving assembly, which can be a gripping cylinder; two clamping jaws 431 disposed on the driving end of the gripping cylinder, the two clamping jaws 431 being brought into contact with each other to clamp the carrier tape; a power member 44 disposed on one side of the first limiting assembly, which can be a driving cylinder; a rotating member 45 disposed on the driving end of the power member 44, which can be a driving motor; and a driving wheel 46 disposed on the rotating shaft of the driving motor. The power rod of the power member 33 is disposed along the third direction, and the rotating shaft of the driving motor is disposed along the second direction. Through the above arrangement, the gripping cylinder and the clamping jaws 431, driven by the moving assembly, can grip the carrier tape from the carrier tape feeding mechanism 10 and transfer the carrier tape to the carrier tape limiting mechanism 20. When the carrier moves to the front of the first limit assembly, the power member 44 will drive the driving wheel 46 to rise to avoid the position. When the carrier is placed at the first limit assembly and limited, the power member 44 drives the driving wheel 46 to press down on the carrier, and drives the driving wheel 46 to rotate through the rotating member 45 to drive the carrier to move along the first direction to the second limit assembly.

[0041] Furthermore, the moving component includes a linear module 41 arranged along the first direction and an assembly plate 42 arranged on the moving part of the linear module 41. The grabbing member 43 is fixed on the assembly plate 42. The linear module 41 drives the grabbing member 43 and the clamping claw 431 to move along the first direction to clamp the carrier from the carrier feeding mechanism 10 and transfer it along the first direction.

[0042] In one embodiment, the carrier tape splicing device further includes a carrier tape buffer mechanism 50 disposed between the carrier tape feeding mechanism 10 and the carrier tape limiting mechanism 20. The carrier tape buffer mechanism 50 can detect whether the carrier tape flow channel 30 is in a state of insufficient material or full material. The carrier tape buffer mechanism 50 includes a second driving member 51 disposed along a third direction at its driving end, and a buffer wheel 52 disposed on the driving end of the second driving member 51. The second driving member 51 can be a driving cylinder. The second driving member 51 drives the buffer wheel 52 to move upward to avoid the position when the clamp 431 grabs the carrier tape from the carrier tape feeding mechanism 10. A shortage signal sensor 53 and a full material signal sensor 54 are disposed on the same side of the buffer wheel 52 and arranged along the third direction. The shortage signal sensor 53 and the full material signal sensor 54 are used to send shortage signals and full material signals, respectively. More specifically, the buffer wheel 52 is slidably mounted on the driving end of the second drive member 51 via a slide rail 55 disposed along the third direction, allowing the buffer wheel 52 to rotate in the second direction. The buffer wheel 52 is provided with a mating portion 521 that engages with the low-stack sensor 53 and the full-stack sensor 54. The mating portion 521 is located between the low-stack sensor 53 and the full-stack sensor 54. After the clamp 431 grabs the carrier tape from the carrier tape feeding mechanism 10, the carrier tape passes under the buffer wheel 52. When the carrier tape flow channel 30 is full, the buffer wheel 52 moves downward under its own weight, passing through the mating portion 521 and triggering the full-stack sensor 54, causing the carrier tape feeding mechanism 10 to stop feeding. When the tape flow channel is low on material, the buffer wheel 52 moves upward under the force of the carrier tape, passing through the mating portion 521 and triggering the low-stack sensor 53, causing the carrier tape feeding mechanism 10 to resume feeding. The above arrangement solves the problem that the carrier tape feed amount cannot be accurately controlled due to the large inertia of the carrier tape on the winding shaft of the carrier tape feeding mechanism, and the carrier tape may be deformed due to over-pulling or loosened due to over-loosening, making it impossible to cut the carrier tape.

[0043] In one embodiment, the assembly plate 42 is further provided with a carrier tape cutting assembly. The carrier tape cutting assembly includes a third drive member 61 having a drive end movable in a second direction. The third drive member 61 can be a drive cylinder, a rotary drive member 62 disposed at the drive end of the third drive member 61, and a cutting blade 63 disposed at the drive end of the rotary drive member 62. The rotary drive member 62 can drive the cutting blade 63 to rotate about the first direction. The cutting blade 63 is disposed perpendicular to the first direction. When the carrier tape at the carrier tape feeding mechanism 10 is nearly exhausted, the buffer wheel 52 moves upward, triggering the out-of-tape signal sensor 53 via the mating portion 521. The second drive member 51 then drives the buffer wheel 52 upward, straightening the carrier tape. The cutting blade 63 is then driven to the stretched carrier tape by the linear module 41 and the third drive member 61. The rotary drive member 62 then drives the cutting blade 63 to rotate, cutting the carrier tape.

[0044] In one specific embodiment, the assembly plate 42 further includes a pin assembly comprising a fourth drive member 64 with a driving end disposed along the second direction, a fifth drive member 65 disposed on the driving end of the fourth drive member 64, and a pin 66 disposed on the driving end of the fifth drive member 65. The driving end of the fifth drive member 65 is disposed along the third direction, and the pin 66 is disposed along the third direction. A strip-shaped through hole 31 extending along the first direction is provided above the carrier tape flow channel 30. The fourth drive member 64 and the fifth drive member 65 cooperate to pass the pin 66 through the strip-shaped through hole 31 and insert it into the pin hole of the carrier tape. The linear module 41 then drives the pin 66 to move the carrier tape within the carrier tape flow channel 30 along the first direction to the splicing position, thereby resolving the difficulty of carrier tape splicing and debugging, reducing the difficulty of splicing and debugging, and improving splicing accuracy.

[0045] To provide power for the first limiting plate 23 to move in the second direction, a bolt 67 extending in the second direction is provided on the driving end of the third driving member 61. The bolt 67 engages with the first limiting plate 23. Driven by the third driving member 61, the bolt 67 abuts against the sidewall of the first limiting plate 23 and pushes the first limiting plate 23 inward in the second direction to limit the carrier tape.

[0046] Regarding the specific structure of the carrier tape feeding mechanism, it includes a winding shaft 11 on which a carrier tape roll is wound, a rotating assembly for driving the winding shaft 11 to rotate in a second direction, and a retaining cylinder 12 for driving the retaining cylinder 12 in the second direction. The retaining cylinder 12 includes a rotating motor 13 and a friction wheel 14 coupled to the rotating motor 13 via a transmission belt 15. The friction wheel 14 corresponds to the end of the winding shaft 11. When the carrier tape is insufficient and needs to be fed, the friction wheel 14 is connected to the winding shaft 11 under the drive of the retaining cylinder 12, and the rotating motor 13 drives the winding shaft 11 to rotate and feed the tape. When the carrier tape is full and no longer needs to be fed, the retaining cylinder 12 drives the retaining cylinder 12 to separate the friction wheel 14 from the winding shaft 11.

[0047] The working process of the carrier tape splicing device provided by the utility model is as follows:

[0048] Splicing action: The moving assembly drives the clamping jaw 431 to the discharge port of the carrier tape feeding mechanism 10. The clamping jaw 431 grasps the carrier tape, and the moving assembly drives the carrier tape toward the carrier tape flow channel 30. The driving end of the second driving member 51 of the carrier tape buffer mechanism 50 extends upward to avoid the clamping jaw 431 and the grabbing cylinder. The moving assembly moves the carrier tape to the carrier tape limiting mechanism 20. The grabbing cylinder and clamping jaw 431 release the carrier tape, and the moving assembly drives the bolt 67 on the third driving member 61 to move to the first limiting assembly and correspond to the position of the first limiting plate 23. The lifting member 22 of the first limiting assembly drives the support member 21 to extend upward. The third driving member 61 extends in the second direction, driving the bolt 67 to push the first limiting plate 23, and the carrier tape is limited in the second direction. The power member 44 drives the driving wheel 46 to move downward to contact the carrier tape. The driving wheel 46 begins to rotate under the drive of the rotating member 45, and the carrier tape moves in the first direction toward the carrier tape flow channel 30. When the sensor detects the carrier tape, the first drive member 26 retracts the second limit plate 25 downward to cover the carrier plate 24, effectively limiting the carrier tape in the third direction. The moving assembly then moves the pins 66 to the strip-shaped through-holes 31 above the carrier tape flow channel 30. The fifth drive member 65 then moves the pins 66 downward and inserts them into the pin holes in the carrier tape. The moving assembly then moves again in the first direction, moving the carrier tape to the splicing position. This improves pin insertion accuracy and eliminates the need for adjustment.

[0049] Normal discharge operation: The driving end of the second driving member 51 of the carrier tape buffer mechanism 50 retracts, the driving rod of the avoidance cylinder 12 of the carrier tape feeding mechanism 10 extends, the mating portion 521 on the buffer wheel 52 triggers the out-of-stock signal sensor 53, the friction wheel 14 rotates, driving the carrier tape roll, the buffer wheel 52 triggers the full-stock signal sensor 54, and the friction wheel 14 stops rotating. When the carrier tape roll on the winding shaft is almost used up, the turret tester sends an out-of-stock signal to the rotating assembly in advance, and the friction wheel 14 stops rotating. At this time, when the buffer wheel 52 sends a signal to the out-of-stock signal sensor 53 again, the driving rod of the second driving member 51 of the carrier tape buffer mechanism 50 extends upward, driving the buffer wheel 52 upward, so that the carrier tape is in a straight state. The moving assembly drives the carrier tape cutting assembly to move to the discharge port of the carrier tape feeding mechanism 10. The driving rod of the third driving member 61 extends, and the rotating driving member 62 drives the cutting knife 63 to rotate and cut the carrier tape.

[0050] To sum up, the utility model cooperates with the carrier feeding mechanism, the carrier limiting mechanism, the carrier flow channel and the transfer mechanism, utilizes the first limiting component to limit the carrier in the second direction, and utilizes the second limiting component to limit the carrier in the third direction; and transports the carrier after the limit is completed into the carrier flow channel through the transfer mechanism for subsequent carrier splicing operations. The carrier splicing device can increase the success rate of the carrier entering the carrier flow channel, thereby improving work efficiency and avoiding the situation where the carrier cannot enter the carrier flow channel due to carrier warping or the carrier itself being relatively soft.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
