Description

Technical Field

[0001] This invention relates to the field of reel reel packaging, and more particularly to a reel reel seeker mechanism. Background Technology

[0002] Reel reel trays are widely used for the storage and transportation of electronic components (such as capacitors, resistors, and inductors). They are usually wrapped with a protective tape to provide protection, insulation, and mechanical strength for the electronic components in the tray. However, there are some problems and limitations in the current market. Generally, the protective tape is attached to the outside of the reel tray. In the existing cutting method, the attached protective tape and the material head are often not accurately joined, resulting in the protective tape pressing too hard on the reel tray or not being firmly attached.

[0003] To achieve precise engagement between the tray head and the protective tape, the tray head needs to be located before the protective tape is packaged. Therefore, it is urgent to design a mechanism that can locate the tray head during the handling of the protective tape, so as to adapt to the automated packaging of the tray and improve the overall packaging efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a reel reel head-finding mechanism. Through the design of air blowing and two parallel sensors, the reel can be unwound to a specific length. In conjunction with a reel clamping and conveying device that can clamp the head of the reel, the position of the head of the reel is determined while it is being transported, so that it can be accurately attached to the protective tape in the future.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a reel disc lead-finding mechanism, comprising a frame and a disc flipping device and a tape-applying turntable device mounted thereon. The frame is also provided with a disc unwinding device and a disc pushing structure that pushes the disc placed flat by the disc flipping device to the disc unwinding device. The frame is provided with two parallel lead-finding sensors and a lead-finding air blowing block that blows the lead of the unwound tape from the disc unwinding device into the lead-finding sensors. The signals from the two lead-finding sensors are used to control the unwinding and rewinding of the disc unwinding device. The frame is also provided with a clamping and conveying device for transporting the disc from the disc unwinding device to the tape-applying turntable device, and the clamping and conveying device clamps the lead of the unwound tape from the disc during transport.

[0006] This solution utilizes an air-blowing mechanism and two parallel sensors to control the unwinding state of the material tray based on the signals generated by the two sensors. This allows the material tray to be unwound to a specific length. Combined with a clamping and conveying device that can clamp the tape head, the solution achieves the simultaneous transport and determination of the tape head position of the transported material tray, enabling precise subsequent bonding with the protective tape.

[0007] Preferably, the clamping and conveying device includes a clamping and conveying seat mounted on a frame, a clamping and conveying movable structure that can move horizontally and vertically on the clamping and conveying movable structure, a clamping and conveying movable seat mounted on the clamping and conveying movable structure, a conveying chuck mounted on the clamping and conveying movable seat, and two clamping swing arms sleeved on the main rod of the conveying chuck, and the two clamping swing arms are respectively connected to a first swing arm motor and a second swing arm motor on the clamping and conveying movable seat through a transmission structure, and both clamping swing arms are connected to a clamping block for clamping the head of the material tray.

[0008] This preferred embodiment features two clamping swing arms on the main rod of the pallet chuck, with the main rod as the rotation center, thus enabling the clamping operation to be completed simultaneously with the pallet clamping.

[0009] Preferably, the conveyor seat is provided with two conveyor chucks, and the distance between the centers of the two conveyor chucks is the distance between the centers of the tape-attaching turntable device and the material tray unwinding device. Only the conveyor chucks near the material tray unwinding device are provided with a tape-clamping swing arm.

[0010] This preferred solution improves overall efficiency by using two transfer clamps to simultaneously clamp the tray for finding the tape head and the tray for applying the tape on the tape turntable.

[0011] Preferably, the frame panel has an arc-shaped clamping groove centered on the rotation center of the unwinding device. When the clamping block is clamping the tape head, it is inserted into the clamping groove and moves within the clamping groove to clamp the tape head.

[0012] This preferred solution, through the design of the clamping groove, can limit the running trajectory of the clamping block and also position the transport chuck.

[0013] Preferably, the clamping and conveying movable seat is provided with two vertically oriented pressure plate cylinders symmetrical about the conveying clamping plate device near the material tray unwinding device, and both pressure plate cylinders are connected to pressure plate blocks.

[0014] This preferred solution, through the design of the pressure plate block, can achieve the effect of pressing the plate during the clamping of the material tray, thus preventing the plate from moving during clamping.

[0015] Preferably, the unwinding device includes an unwinding seat mounted on the frame, an unwinding shaft connected to the unwinding seat via a vertically oriented unwinding lifting cylinder, and the unwinding shaft being rotatable relative to the unwinding lifting cylinder. The unwinding shaft is connected to an unwinding rotating motor via an unwinding transmission structure, and the unwinding transmission structure and the unwinding shaft are able to lift and lower each other but cannot rotate relative to each other. An unwinding disc for carrying the material tray is fixedly sleeved on the upper part of the unwinding shaft.

[0016] The material tray unwinding device of this preferred embodiment, through the design of the unwinding lifting cylinder, can ensure that the unwinding tray can support the material tray and detach the material tray from the frame panel, ensuring that it can be unwound along with the unwinding tray.

[0017] Preferably, the material tray turning device includes a turning and lifting structure mounted on the frame, a turning mounting base extending through the frame panel connected to the turning and lifting structure, a first turning motor with a vertically oriented rotating shaft mounted on the turning mounting base, a first turning motor connected to a first turning seat, a second turning motor with a horizontally oriented rotating shaft mounted on the first turning seat, a turning clamp for holding the material tray connected to the second turning motor, a turning movable motor mounted on the first turning seat, a turning movable motor connected to a turning gear, and a turning movable block mounted on the first turning seat via a slide rail, a turning movable block with a turning rack cooperating with the turning gear, and the second turning motor mounted on the turning movable block.

[0018] The preferred embodiment of the tray flipping device can achieve flipping in two vertical directions, thereby enabling changes in the state and position of the tray. The design of the flipping motor and the flipping block allows for adjustment of the position of the flipping block, thus accommodating trays of different sizes. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0027] like Figure 1-2 As shown, the specific structure of the present invention is as follows: a reel disc lead-finding mechanism, including a frame and a disc flipping device 4 and a tape-applying turntable device 7 mounted on it. The frame is also provided with a disc unwinding device 42 and a disc pushing structure 41 that pushes the disc placed flat by the disc flipping device 4 to the disc unwinding device 42. The frame is provided with two parallel lead-finding sensors 44 and a lead-finding air blowing block 43 that blows the lead of the tape unwound by the disc unwinding device into the lead-finding sensors. The signals from the two lead-finding sensors 44 are used to control the unwinding and rewinding of the disc unwinding device 42. The frame is also provided with a clamping and conveying device 46 for transporting the disc on the disc unwinding device 42 to the tape-applying turntable device, and the clamping and conveying device 46 clamps the lead of the tape unwound from the disc during transport.

[0028] In practical use, the tray is first placed on the tray flipping device 4, then placed on the panel of the frame by the tray flipping device 4. The tray is then pushed onto the tray unwinding device 42 by the tray pushing structure 41. The tray unwinding device 42 then rotates the tray to unwind it. Simultaneously, the lead-finding air-blowing block 43 blows air, which blows the lead of the tray into two parallel lead-finding sensors 44 (laser beam sensors) until both sensors generate a sensing signal (laser beam). If the laser signal is intercepted and cannot be received (indicating the generation of a sensing signal), the unwinding stops, and then the winding continues until one of the lead-finding sensors has no signal and the other has a signal, stopping the unwinding device. Each reel is unwound in this way, ensuring that the unwound lead is between the two lead-finding sensors 44, thus providing lead-finding positioning. Then, the lead of the reel is clamped by the clamping and conveying device 46, and the reel is transported to the tape-applying turntable device 7 for subsequent protective tape application.

[0029] like Figure 5-6 As shown, the clamping and conveying device 46 includes a clamping and conveying seat 71 mounted on the frame. The clamping and conveying seat 71 has a clamping and conveying movable structure 72 that can move horizontally and vertically. A clamping and conveying movable base 73 is mounted on the clamping and conveying movable structure 72. Two conveying chucks 74 are mounted on the clamping and conveying movable base 73, and the distance between the centers of the two conveying chucks 74 is the distance between the centers of the tape-attaching turntable device 7 and the material tray unwinding device 42. Two clamping swing arms 77 are sleeved on the main body rod of the conveying chuck 74 closest to the material tray unwinding device 42. Both 77 are connected to the first swing arm motor 75 and the second swing arm motor 76 on the clamping and conveying movable seat 73 via a transmission structure. Both clamping swing arms 77 are connected to clamping blocks 78 for clamping the tape head of the material tray. An arc-shaped clamping groove is provided on the frame panel with the rotation center of the material tray unwinding device as the center. When clamping the tape head, the clamping block is inserted into the clamping groove and moves in the clamping groove to complete the clamping of the tape head. The clamping and conveying movable seat 73 is provided with two vertically oriented pressure plate cylinders 79 that are symmetrical about the conveying clamp 74 near the material tray unwinding device. Both pressure plate cylinders 79 are connected to pressure plate blocks 80.

[0030] The specific operation of the clamping and conveying device 46 is as follows: First, the clamping and conveying movable structure 72 drives the clamping and conveying movable seat 73 to move up and down and horizontally, so that the clamping block 78 can be inserted into the clamping groove 45. At this time, there is still a gap between the conveying clamp 74 and the material tray. Then, the pressing plate cylinder 79 drives the pressing plate block 80 to descend, so that the pressing plate block 80 presses down on the material tray. Then, the clamping and conveying movable structure drives the clamping and conveying movable seat 73 to continue to descend, so that the conveying clamp 74 clamps the material tray. During this process, the pressing plate cylinder 79 will retract, and the pressing plate block 80 will remain relatively stationary. Then, the first swing arm motor 75 and the second swing arm motor 76 drive the clamping swing arm 77 to rotate, so that the clamping block 78 completes the clamping of the tape head. Then, the clamping and conveying movable structure 72 drives the clamping movable seat 73 to move as a whole, moving the material tray to the tape-attaching turntable device 7.

[0031] like Figure 3 As shown, the unwinding device 42 includes an unwinding seat 51 mounted on the frame. An unwinding shaft 54 ​​is connected to the unwinding seat 51 via a vertically oriented unwinding lifting cylinder 56. The unwinding shaft 54 ​​can rotate relative to the unwinding lifting cylinder 56. The unwinding shaft 56 is connected to an unwinding rotating motor 52 via an unwinding transmission structure 53. The unwinding transmission structure 53 and the unwinding shaft 54 ​​can lift and lower each other but cannot rotate relative to each other. An unwinding disc 57 for supporting the material tray is fixedly sleeved on the upper part of the unwinding shaft 54.

[0032] When the material tray is pushed to the material tray unwinding device 42 by the material tray pushing structure 41, the unwinding lifting cylinder 56 first drives the unwinding shaft 54 ​​and the unwinding reel 57 to rise as a whole, so that the upper part of the unwinding shaft 54 ​​passes through the material tray, and the material tray is supported by the unwinding reel 57. Then, the unwinding motor 52 is started, and the unwinding transmission structure 53 drives the unwinding shaft 54 ​​to rotate, thereby realizing unwinding and rewinding. The air blowing and sensing of the lead seeker are used to realize lead seeker.

[0033] like Figure 4 As shown, the material tray flipping device 4 includes a flipping and lifting structure 62 mounted on the frame. A flipping mounting base 61 extending through the frame panel is connected to the flipping and lifting structure 62. A first flipping motor 63 with a vertically oriented rotating shaft is mounted on the flipping mounting base 61. The first flipping motor 63 is connected to a first flipping seat 64. A flipping movable motor 65 is mounted on the first flipping seat 64. The flipping movable motor 65 is connected to a flipping gear. A flipping movable block 66 is mounted on the first flipping seat via a slide rail. A flipping rack that cooperates with the flipping gear is mounted on the flipping movable block 66. A second flipping motor 67 with a horizontally oriented rotating shaft is mounted on the flipping movable block 66. A flipping clamp 68 for clamping the material tray is connected to the second flipping motor 67.

[0034] In practical use, the material tray is first placed on the flipping clamp 68 by manual labor or a robotic arm. The flipping clamp 68 holds the material tray. Then, according to the size of the material tray, the flipping motor 65 drives the flipping gear to rotate, which moves the flipping block 66. Then, the first flipping motor 63 rotates 180 degrees, and the second flipping motor 67 rotates 90 degrees, thus completing the flipping and repositioning of the material tray from vertical to horizontal. Then, the flipping lifting structure 62 drives the flipping mounting base 61 to descend as a whole, and then places the material tray on the panel of the frame. To avoid interference, a groove with a width smaller than the diameter of the material tray is opened on the panel.
