[0002] Carrier tapes are mainly used in the electronic component mounting industry. They are used in conjunction with cover tapes to carry and store electronic components such as resistors, capacitors, transistors, and diodes in the pockets of the carrier tape, and form a closed package by sealing the cover tape above the carrier tape to protect the electronic components from being contaminated and damaged during transportation. During the mounting of electronic components, the cover tape is peeled off, and the automatic mounting equipment accurately positions through the indexing holes of the carrier tape, and sequentially takes out the components placed in the pockets and mounts them on the integrated circuit board.

The outer wall of the reciprocating lead screw 311 is connected with a worm gear 312. The worm gear 312 meshes with a worm 39. A ball slider 313 is slidably mounted on the base 1. Two push blocks 314 are mounted on the ball slider 313 through springs. A reciprocating thread groove is provided on the reciprocating lead screw 311. The inner wall of the ball slider 313 is slidably connected with the reciprocating thread groove of the reciprocating lead screw 311 through balls. The worm 39 drives the reciprocating lead screw 311 to rotate through the worm gear 312. When the reciprocating lead screw 311 rotates, it drives the ball slider 313 to slide left and right reciprocally on the base 1 through the cooperation of the reciprocating thread groove and the balls. The two push blocks 314 contact the sliding table 37 during the movement. A return spring is provided on the sliding table 37. The elastic force of the springs on the two push blocks 314 is greater than the elastic force of the return spring on the sliding table 37. The two push blocks 314 push the sliding table 37 to the right. When the sliding table 37 moves to the right, it drives the motor 38, the worm 39 and the third gear 310 to move to the right together through the bracket. The third gear 310 meshes with the second gear 36 during the movement, so that the third gear 310 disengages from contact with the first gear 35 and then turns to contact with the second gear 36. The third gear 310 drives the mounting shaft 31 to rotate through the second gear 36. When the mounting shaft 31 rotates, it drives the mounting arm 32 to rotate. The mounting arm 32 drives the first shaft 33 and the second shaft 34 to rotate, so that the positions of the first shaft 33 and the second shaft 34 are interchanged, the wound take-up reel 6 on the first shaft 33 moves to the right, and the unwound take-up reel 6 on the second shaft 34 moves to the left. The first shaft 33 and the second shaft 34 cooperate to keep the winding operation circulating, which speeds up the operation rhythm and smoothness. A gravity rod 315 is rotatably mounted on the cover plate 2 through a round rod. A pressing block 316 is hinged to the end of the gravity rod 315 away from the cover plate 2. The pressing block 316 is located in one of the take-up reels 6.

Through the setting of the circulating winding assembly 3, the first shaft 33 and the second shaft 34 can drive the take-up reel 6 to perform the winding operation in a cycle. After the take-up reel 6 completes the winding, the first shaft 33 and the second shaft 34 can automatically change positions, so that a new take-up reel 6 continues to perform the winding operation. The staff disassembles and replaces the wound take-up reel 6, so that the process of replacing the take-up reel 6 does not affect the winding operation, improving the smoothness of the operation. The interruption time of the winding operation is short, improving the work efficiency. Through the setting of the gravity rod 315 and the pressing block 316, the pressing block 316 can press the tape being wound, improving the tightness of the tape and preventing the tape from being loosely wound and affecting storage and transportation.;

[0036] Further, please refer to Figure 6 - Figure 8The cutting assembly 4 is used for cutting the wound carrier tape. The cutting assembly 4 is arranged on the circulating winding assembly 3. The cutting assembly 4 includes a hollow column 41. The hollow column 41 is installed on the inner wall of the mounting arm 32. The outer surfaces of both ends of the hollow column 41 are respectively connected with fixed knives 42. The fixed knife 42 is hinged with a movable knife 43. The movable knife 43 is hinged with a connecting rod 44. Two inner sliders 45 are slidably installed on the inner wall of the hollow column 41. A sliding shaft 46 is connected between the two inner sliders 45. A heavy hammer 47 is slidably connected to the outer wall of the sliding shaft 46. The heavy hammer 47 contacts the two inner sliders 45 in turn during the movement. The heavy hammer 47 is located at the hollow column 41. The weight 47 is located at a high position in the hollow column 41 as the hollow column 41 rotates, so that the weight 47 falls down by gravity. The two inner sliders 45 are arranged in a mirror image. The two connecting rods 44 are respectively hinged to the two inner sliders 45. After the weight 47 falls, it drives the two inner sliders 45 to move downward. During the downward movement of the lower inner slider 45, the lower movable knife 43 is driven to rotate through the connecting rod 44, so that the angle between the movable knife 43 and the fixed knife 42 is at a right angle. During the downward movement of the upper inner slider 45, the upper movable knife 43 is driven to flip upward through the connecting rod 44, so that a gap is formed between the upper movable knife 43 and the fixed knife 42. Shear force, a part of the carrier tape is located between the upper movable knife 43 and the fixed knife 42, and the movable knife 43 and the fixed knife 42 are closed to cut the carrier tape, thereby achieving the effect of automatic cutting; a resistance ring 49 is installed on the inner wall of the hollow column 41, and buffer rings 48 are connected to the two ends of the weight 47 respectively. The two buffer rings 48 contact with the resistance rings 49 in turn during the movement, and there is a certain friction force between the buffer rings 48 and the resistance rings 49, so that before the hollow column 41 rotates to vertical, the resistance ring 49 presses against the weight 47 through the buffer ring 48, and the weight 47 cannot fall temporarily. When the hollow column 41 is vertical, the inside of the hollow column 41 The friction force of the wall and the sliding shaft 46 on the weight 47 is reduced, and the weight 47 begins to fall, increasing the falling impact force, so that the shear force between the movable knife 43 and the fixed knife 42 is increased; through the setting of the cutting component 4, the two movable knives 43 and the two fixed knives 42 cooperate to cut the carrier tape in turn, so that the carrier tape is separated from the connection between the winding drum 6 that has completed the winding, thereby achieving the effect of automatic cutting and reducing the operating steps of the staff; through the cooperation between the buffer ring 48, the resistance ring 49 and the weight 47, the shear force of cutting is more concentrated, the timing of cutting is more accurate, and the situation of incomplete cutting is avoided.

[0037] Further, see Figure 9 - Figure 12, a material pressing assembly 5, which is used to press the end of the carrier tape during winding. The material pressing assembly 5 is arranged on the circulating winding assembly 3. The material pressing assembly 5 includes a first chute 51 and a second chute 57. The first chute 51 and the second chute 57 are respectively installed on the base 1 through brackets. The first chute 51 and the second chute 57 are respectively located outside the first shaft 33 and the second shaft 34. Slide rings 52 are respectively slidably installed on the first shaft 33 and the second shaft 34. A lever 53 is connected to the slide ring 52, and a material pressing rod 54 is connected to the slide ring 52. Inner slide frames 56 are respectively installed on the first shaft 33 and the second shaft 34. The outer walls of the two material pressing rods 54 are respectively slidably connected to the inner walls of the two inner slide frames 56. The lever 53 contacts the first chute 51 and the second chute 57 in sequence during movement. An arc-shaped groove is provided on the winding drum 6. The material pressing rod 54 passes through the arc-shaped groove of one of the winding drums 6 during movement. When the lever 53 slides along the first chute 51, it is pushed by the first chute 51 and moves towards the direction close to the winding drum 6. The first chute 51 drives the slide ring 52 to slide towards the direction close to the winding drum 6. The slide ring 52 drives the material pressing rod 54 to pass through the arc-shaped groove on the winding drum 6. An installation groove is provided at the bottom of the material pressing rod 54. A spring piece 55 is installed in the installation groove of the material pressing rod 54. After the material pressing rod 54 moves into place, it presses on the carrier tape. The spring piece 55 in the installation groove below the material pressing rod 54 applies pressure to the carrier tape. After the lever 53 enters the second chute 57, the material pressing rod 54 is withdrawn from the winding drum 6. The two material pressing rods 54 alternately press the end of the carrier tape. Workers do not need to use adhesive tape to stick the end of the carrier tape before winding, reducing the operation steps of workers and saving the input of resources. The levers 53 on the first shaft 33 and the second shaft 34 take turns to enter the first chute 51 and the second chute 57 in sequence, and the two material pressing rods 54 take turns to perform the material pressing operation; through the setting of the material pressing assembly 5, the two material pressing rods 54 alternately perform the material pressing work. Before the winding drum 6 starts winding, the material pressing rod 54 automatically inserts into the winding drum 6 to press the carrier tape. After the winding drum 6 finishes winding, the material pressing rod 54 automatically withdraws, reducing the operation steps of workers manually sticking the end of the carrier tape, improving the automation level, and further improving the work efficiency.

[0038] With the above structure, the working principle of this case is as follows: The staff sleeved two winding drums 6 on the first shaft 33 and the second shaft 34 respectively. There are flat keys on the first shaft 33 and the second shaft 34, and key grooves are arranged on the inner side of the winding drum 6. The flat keys match the key grooves. The first shaft 33 and the second shaft 34 can drive the winding drum 6 to rotate. Start the motor 38, the motor 38 drives the worm 39 to rotate, the worm 39 drives the third gear 310 to rotate, the third gear 310 drives the first gear 35 on the first shaft 33 to rotate, and the first gear 35 drives the first shaft 33 to rotate. There are multiple guide cylinders arranged on the base 1. After being guided by multiple guide cylinders, the carrier tape contacts the winding drum 6 on the first shaft 33. The winding drum 6 on the first shaft 33 completes the winding operation through rotation. While the worm 39 is rotating, the worm 39 drives the reciprocating screw rod 311 to rotate through the worm gear 312. When the reciprocating screw rod 311 rotates, it drives the ball slider 313 to slide left and right reciprocally on the base 1 through the cooperation of the reciprocating thread groove and the ball. Since the number of turns of the reciprocating screw rod 311 is related to the moving distance of the ball slider 313, and the number of turns of the winding drum 6 is related to the number of turns of the reciprocating screw rod 311. During the winding process of the winding drum 6, the ball slider 313 first moves to the left and then turns to move to the right. When the winding drum 6 rotates a certain number of turns, that is, when the winding is completed, during the process of the ball slider 313 moving to the right, the two push blocks 314 on the ball slider 314 contact the slide table 37. Since the elastic force of the springs on the two push blocks 314 is greater than the elastic force of the return spring on the slide table 37, the two push blocks 314 push the slide table 37 to the right. When the slide table 37 moves to the right, it drives the motor 38, the worm 39 and the third gear 310 to move to the right together through the bracket, so that the third gear 310 disengages from the contact with the first gear 35. When the slide table 37 moves to the right in place, the third gear 310 contacts the second gear 36. The third gear 310 drives the mounting shaft 31 to rotate through the second gear 36. When the mounting shaft 31 rotates, it drives the mounting arm 32 to rotate. During this process, the slide table 37 first moves to the right and then turns to move to the left. The springs on the two push blocks 314 expand and contract at this time, and the slide table 37 remains stationary. When the mounting arm 32 rotates 180 degrees, the thrust of the two push blocks 314 on the slide table 37 begins to decrease until it disappears. The slide table 37 returns to its original position through the elastic force of the return spring. When the slide table 37 returns to its original position, the third gear 310 disengages from the engagement with the second gear 36 and engages with another first gear 35. During the rotation of the mounting arm 32, the mounting arm 32 drives the first shaft 33 and the second shaft 34 to rotate, so that the positions of the first shaft 33 and the second shaft 34 are interchanged. The wound winding drum 6 on the first shaft 33 moves to the right, and the unwound winding drum 6 on the second shaft 34 moves to the left. The functions of the first shaft 33 and the second shaft 34 are the same. After the third gear 310 engages with the first gear 35 on the second shaft 34, it drives the second shaft 34 to rotate through the first gear 35, and the winding drum 6 on the second shaft 34 starts the winding operation. At this time, the staff disassembles the winding drum 6 on the first shaft 33.Install a new take-up reel 6, so that the first shaft 33 and the second shaft 34 cooperate to keep the take-up operation cycling, which speeds up the operation rhythm and smoothness; the gravity rod 315 falls by gravity, and the pressing block 316 on the gravity rod 315 presses on the tape being taken up, improving the tightness of the tape. When the two take-up reels 6 change positions, the gravity rod 315 flips upward following the take-up reel 6. When the pressing block 316 disengages from the take-up reel 6, the gravity rod 315 falls by gravity. After the gravity rod 315 falls in place, another take-up reel 6 contacts the pressing block 316, and the gravity rod 315 and the pressing block 316 are reset accordingly, so that the pressing block 316 remains in contact with the take-up reel 6 in the process of taking up; through the setting of the circulating take-up assembly 3, the first shaft 33 and the second shaft 34 can cyclically drive the take-up reel 6 to perform the take-up operation. After the take-up reel 6 completes the take-up, the first shaft 33 and the second shaft 34 can automatically change positions, enabling the new take-up reel 6 to continue the take-up operation. The staff disassembles and replaces the take-up reel 6 that has completed the take-up, so that the process of replacing the take-up reel 6 does not affect the take-up operation, improving the smoothness of the operation. The interruption time of the take-up operation is short, improving the work efficiency; through the setting of the gravity rod 315 and the pressing block 316, the pressing block 316 can press the tape being taken up, improving the tightness of the tape and preventing the tape from being slack during take-up, which may affect storage and transportation.,

[0039] When the mounting arm 32 rotates, the hollow column 41 rotates accordingly. When the hollow column 41 rotates, the two fixed knives 42 are turned over, so that the two fixed knives 42 exchange positions. In this process, the weight 47 is located at a high position in the hollow column 41 as the hollow column 41 rotates, so that the weight 47 falls by gravity. After the weight 47 falls, it drives the inner slider 45 located below to move downward. The inner slider 45 drives another inner slider 45 to move downward through the sliding shaft 46. During the downward movement of the lower inner slider 45, the lower movable knife 43 is driven to rotate through the connecting rod 44, so that the angle between the movable knife 43 and the fixed knife 42 is at a right angle. During the downward movement of the upper inner slider 45, the upper movable knife 43 is driven to rotate through the connecting rod 44. The hollow column 41 is flipped upside down, so that a shear force is formed between the upper movable knife 43 and the fixed knife 42. When the two winding drums 6 exchange positions, the carrier tape on the winding drum 6 that has been wound up is placed on the empty winding drum 6, and a part of the carrier tape is located between the upper movable knife 43 and the fixed knife 42. When the movable knife 43 and the fixed knife 42 are closed, the carrier tape is cut off, achieving the effect of automatic cutting. When the positions are exchanged next time, the movable knife 43 and the fixed knife 42 that were previously located at the bottom move to the top for cutting, and the movable knife 43 and the fixed knife 42 that were previously located at the top move to the bottom and open; when the hollow column 41 rotates, the buffer ring 48 located at the bottom of the weight 47 contacts the resistance ring 49, and there is a certain distance between the buffer ring 48 and the resistance ring 49. The friction force makes the resistance circle 49 resist the weight 47 through the buffer circle 48 before the hollow column 41 rotates to the vertical position, and the weight 47 cannot fall temporarily. When the hollow column 41 is vertical, the friction force of the inner wall of the hollow column 41 and the sliding shaft 46 on the weight 47 is reduced, and the weight 47 starts to fall. During the falling process, the buffer circle 48 located at the top directly passes through the resistance circle 49 due to the large impact force of falling. The buffer circle 48 at the bottom can also play a certain buffering and shock-absorbing effect when the weight 47 hits the inner slider 45, so as to avoid the loosening of the connection between the inner slider 45, the connecting rod 44 and the movable knife 43 after long-term use, thereby affecting the use. Through the arrangement of the buffer circle 48 and the resistance circle 49, The heavy hammer 47 falls only when the hollow column 41 is vertical. The impact force of the fall is concentrated, which increases the shear force between the movable knife 43 and the fixed knife 42. At this time, the position of the carrier tape is relatively low, which avoids the situation where the carrier tape is too high and cut in advance, resulting in incomplete cutting. Through the setting of the cutting component 4, the two movable knives 43 and the two fixed knives 42 cooperate to cut the carrier tape in turn, so that the carrier tape is separated from the connection between the winding drum 6 that has completed the winding, achieving the effect of automatic cutting and reducing the operating steps of the staff. Through the cooperation between the buffer ring 48, the resistance ring 49 and the heavy hammer 47, the shear force of cutting is relatively concentrated, the timing of cutting is relatively accurate, and the situation of incomplete cutting is avoided.

[0040] When the second shaft 34 moves to the left, the lever 53 on the second shaft 34 enters the first slide groove 51. When the lever 53 slides along the first slide groove 51, it is subjected to the reverse thrust of the first slide groove 51 and moves toward the direction close to the winding drum 6. The first slide groove 51 drives the slip ring 52 to slide toward the direction close to the winding drum 6. The slip ring 52 drives the pressing rod 54 to slide toward the direction close to the winding drum 6 on the inner slide 56. The pressing rod 54 passes through the arc groove on the winding drum 6 during the movement. At the same time, the carrier belt is placed on the winding drum 6, and the pressing block 316 presses When the first shaft 33 moves to the right, the lever 53 on the first shaft 33 enters the second slide groove 57 and is in contact with the upper shaft 33. The above steps are similar, because the inclination direction of the second slide groove 57 is opposite to that of the first slide groove 51, when the lever 53 slides in the second slide groove 57, the lever 53 drives the slip ring 52 to move away from the winding drum 6, so that the pressing rod 54 draws out the winding drum 6. When the pressing rod 54 draws out the winding drum 6, the lever 53 is out of contact with the second slide groove 57, and the staff then replaces the winding drum 6. The two pressing rods 54 alternately press the end of the carrier tape, and the staff does not need to use tape to stick the end of the carrier tape before winding, which reduces the staff's operation steps. It also saves investment in resources. The levers 53 on the No. 1 shaft 33 and the No. 2 shaft 34 enter the No. 1 slide groove 51 and the No. 2 slide groove 57 in turn, and the two pressing rods 54 perform the pressing operation in turn. Through the setting of the pressing assembly 5, the two pressing rods 54 perform the pressing work alternately. Before the winding drum 6 starts to reel in, the pressing rod 54 is automatically inserted into the winding drum 6 to press the carrier tape. After the winding drum 6 completes reeling, the pressing rod 54 is automatically pulled out, which reduces the operating steps of the staff manually pasting the end of the carrier tape, improves the level of automation, and further improves work efficiency.
