[0002] Circuit board production equipment refers to the general term for various equipment used in the production of circuit boards. Among them is an automatic printing placement machine. When the placement machine is running, the placement machine needs to accurately install the electronic components on multiple carriers onto the circuit board.

[0003] In actual applications, workers will use boxes to store used carrier tapes. At this time, multiple carrier tapes are prone to entanglement with each other. Therefore, when the box is full of carrier tapes, the workers need to cut off the unused carrier tapes in order to move the box away. However, due to the large number of carrier tapes, the workers need to spend more time on the operation, which reduces their work efficiency.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The spring is used to prevent the blade from contacting the carrier tape when the blade is in contact with the carrier tape, thereby saving the operating time of the staff and improving the working efficiency of the staff.

When the limiting frame slides, it will drive the limiting rod to slide. At this time, the limiting rod reaches the function of limiting the sliding path of the limiting frame. By setting the limiting structure, the position of the carrier tape can be limited when cutting the carrier tape, thereby making it more convenient for the staff to operate.

[0029] By setting a shielding structure, when the shielding structure is needed, the rectangular frame is rotated, and the rotation of the rectangular frame will drive the adjustment plate to rotate.

When the hook is hung on the surface of the card plate, the card plate reaches the effect of limiting the hook position and then limiting the rope position. By hanging the hook on the card plate in different positions, the rectangular frame can be limited to different positions. Then the adjusting plate is pulled, and when the adjusting plate slides along the inner wall of the rectangular frame, it will drive the block to slide along the inner wall of the adjusting hole. The limit hole reaches the effect of limiting the sliding path of the block and then limiting the sliding path of the adjusting plate. When the adjusting plate slides to a suitable position, the plug rod is slid along the surface of the bent plate. When the plug rod slides into the inner wall of the plug hole, the plug rod reaches the effect of limiting the position of the adjusting plate. By setting a shielding structure, the light above the control panel can be blocked, thereby preventing strong light from being irradiated on the surface of the control panel to generate reflections, which affects the staff's viewing of the control panel, thereby further improving the practicality of the equipment.

[0046] like Figure 7 , Figure 8 and Fig. 9 As shown, the shielding structure 6 includes a rectangular frame 61, which is rotatably connected to the SMT machine body 1, an adjustment plate 62 is slidably connected to the inner wall of the rectangular frame 61, a rope 63 is fixedly connected to the upper surface of the rectangular frame 61, and a hook 64 is fixedly connected to the end of the rope 63 away from the rectangular frame 61, and a positioning plate 65 is fixedly connected to the position of the SMT machine body 1 relative to the hook 64, and a plurality of clamping plates 66 are fixedly connected to the side of the positioning plate 65 close to the hook 64, and the size of the clamping plate 66 is adapted to the size of the hook 64.

A bending plate 67 is fixedly connected to one side of the rectangular frame 61 close to the rope 63. The vertical section of the bending plate 67 is "L"-shaped. A plug rod 68 slides through the surface of the short arm of the bending plate 67. The adjustment plate 62 is provided with a plurality of holes relative to the position of the plug rod 68. The size of the holes on the adjustment plate 62 is matched with the size of the plug rod 68. When the plug rod 68 is engaged with the holes, the plug rod 68 serves to limit the position of the adjustment plate 62.

[0047] Working principle: By setting the cutting structure 4, when the cutting structure 4 needs to be used, first press the pull plate 47 in the direction close to the fixed plate 42, and the connection plate 46 moves with the help of the pull plate 47 to drive the blade 45 to slide along the slide plate 44. At this time, the blade 45 will slide into the cutting hole 49, and the sliding of the connection plate 46 will squeeze the spring 48. At this time, the spring 48 is in a compressed state, and then pull the pull plate 47. The movement of the pull plate 47 will drive the connection plate 46 to move. When the connection plate 46 moves, it will drive the blade 45 to move. When the blade 45 contacts the carrier tape 7, the blade 45 will cut the carrier tape 7, and when the blade 45 slides, it will also drive the slide plate 44 along The inner wall of the slide hole 43 slides, and at this time the slide hole 43 limits the sliding path of the slide plate 44, and then limits the sliding path of the blade 45. When the cutting is completed, the pull plate 47 is released, and the spring 48 begins to extend. The connecting plate 46 will slide in the direction away from the slide plate 44 with the help of the elastic force of the spring 48. The sliding of the connecting plate 46 will drive the blade 45 to slide. The spring 48 can prevent the blade 45 from contacting the carrier 7 as much as possible when the blade 45 is not in use. By setting the cutting structure 4, it is convenient for the staff to quickly cut multiple carriers 7, thereby saving the staff's operating time and improving the staff's work efficiency.

[0048] By setting the limiting structure 5, when the limiting structure 5 needs to be used, the driving disk 56 is rotated, and the driving disk 56 will drive the screw 52 to rotate along the surface of the square plate 51, and the driving disk 56 can facilitate the rotation of the screw 52, ​​and the anti-sliding block 57 can facilitate the rotation of the driving disk 56. When the screw 52 rotates, it will drive the transmission plate 53 to move away from the square plate 51 with the help of the thread, and the movement of the transmission plate 53 will drive the limiting frame 54 to move. When the limiting frame 54 contacts the carrier tape 7, the limiting frame 54 can press the carrier tape 7 tightly, thereby facilitating the staff to cut the carrier tape 7. When the limiting frame 54 slides, it will drive the limiting rod 55 to slide. At this time, the limiting rod 55 can limit the sliding path of the limiting frame 54. By setting the limiting structure 5, the position of the carrier tape 7 can be limited when cutting the carrier tape 7, thereby making it more convenient for the staff to operate.

[0049] By setting the shielding structure 6, when the shielding structure 6 needs to be used, the rectangular frame 61 is rotated, and the rotation of the rectangular frame 61 will drive the adjustment plate 62 to rotate. When the adjustment plate 62 is rotated to a suitable position, the hook 64 is moved. When the hook 64 is hung on the surface of the card plate 66, the card plate 66 reaches the effect of limiting the position of the hook 64 and then limiting the position of the rope 63. By hanging the hook 64 on the card plate 66 at an unused position, the rectangular frame 61 can be limited to different positions. Then, the adjustment plate 62 is pulled, and when the adjustment plate 62 slides along the inner wall of the rectangular frame 61, it will drive the stopper 69 along the adjustment hole The inner wall slides, and the limit hole reaches the function of limiting the sliding path of the stop block 69 and then limiting the sliding path of the adjustment plate 62. When the adjustment plate 62 slides to a suitable position, the insertion rod 68 is slid along the surface of the bending plate 67. When the insertion rod 68 slides along the inner wall of the hole, the insertion rod 68 reaches the function of limiting the position of the adjustment plate 62. By setting the shielding structure 6, the light above the control panel 3 is blocked, thereby preventing strong light from being reflected when it hits the surface of the control panel 3, which affects the staff's viewing of the control panel 3, thereby further improving the practicality of the equipment.
