Description
Technical Field
[0001] The present invention belongs to the technical field of automatic tape splicing for pick - and - place machines, and in particular relates to a tape temporary storage mechanism and a tape splicing machine. Background Art
[0002] SMT (Surface Mount Technology) is the core technology in modern electronic manufacturing and is widely used in fields such as consumer electronics, communication equipment, and automotive electronics. The core equipment of SMT chip - mounting technology is the SMT pick - and - place machine, which can automatically grasp components and accurately place them on the PCB through an electronic eye recognizer.
[0003] Under normal circumstances, when the tape in the pick - and - place machine is about to run out, a tape splicing machine is required to join the tape head of the new tape reel and the tape tail of the old tape reel. After joining, the new tape reel is placed at the preset working position of the pick - and - place machine. Therefore, most tape splicing machines are usually equipped with a buffer bin to temporarily store the tape of the old tape reel. The buffer bin can be set in a fixed or rotary form. The fixed buffer bin is usually fixedly installed on the machine table. To save space, the bottom size of the buffer bin is usually set to be larger than the size of the top feed inlet of the buffer bin, and the bottom of the buffer bin is arranged below the tape feeding component. This can enable the buffer bin to save space while ensuring the buffer capacity. However, during the specific process of storing the tape, due to the small size of the feed inlet, the tape is prone to congestion at the feed inlet, which affects the smooth entry of the tape into the buffer bin and also causes creases on the tape. Summary of the Invention
[0004] The purpose of the present invention is to provide a tape temporary storage mechanism and a tape splicing machine to solve the problem that the conventional buffer bin in the prior art can cause the tape to be easily congested at the feed inlet.
[0005] To achieve this purpose, the present invention adopts the following technical solutions:
[0006] In the first aspect, a tape temporary storage mechanism is provided, which includes a base, a tape feeding component, and a tape bin, wherein:
[0007] The silo includes a silo body, a rotating member, a guide wheel, and a first driving member. The silo body is fixedly arranged on the base. The silo body has a storage cavity for storing a strip. The opening of the storage cavity faces upward and extends in a first direction. The middle of the rotating member is hinged to the silo body. The first end of the rotating member is located at the first end of the opening in the first direction. The guide wheel is installed at the first end of the rotating member. The guide wheel is at least configured to support and guide the strip to be stored in the storage cavity. The driving end of the first driving member is connected to the second end of the rotating member. The first driving member is configured to drive the second end of the rotating member to rotate, so as to drive the guide wheel to approach or move away from the opening, thereby changing the size of the opening;
[0008] The feeding assembly is arranged on the base and on the side of the opening away from the guide wheel. The feeding assembly includes a feeding table, a conveying ratchet, and a second driving member. The feeding table is installed on the base. The feeding table is configured to receive the strip on the guide wheel. The conveying ratchet is rotatably arranged on the base. The teeth of the conveying ratchet are engaged in the material clamping holes of the strip. The driving end of the second driving member is connected to the conveying ratchet. The second driving member is configured to drive the conveying ratchet to rotate, so as to feed the strip into the silo body;
[0009] In the working state, the first driving member drives the guide wheel to move away from the opening to a first preset position, so that the opening becomes larger; in the waiting state, the first driving member drives the guide wheel to approach the opening to a second preset position, so that the opening becomes smaller.
[0010] Furthermore, a material pressing assembly is arranged on the base. The material pressing assembly includes a third driving member, a lifting seat, and a guiding pressing block. The lifting seat is arranged on the base in a liftable manner. The guiding pressing block is installed on the lifting seat and is located directly above the opening. The bottom of the guiding pressing block has a material pressing arc surface. The fixed end of the third driving member is installed on the base. The driving end of the third driving member is connected to the lifting seat. The third driving member is configured to drive the guiding pressing block to rise to a high position or a low position through the lifting seat. The third driving member drives the guiding pressing block to the low position to cooperate with the material pressing arc surface of the guiding pressing block to press the strip located at the opening.
[0011] Furthermore, the tape temporary storage mechanism further includes a transverse movement assembly, which includes a transverse movement driving member and a transverse movement seat. The transverse movement seat is disposed on the base so as to be able to approach or move away from the magazine body along a second direction. The pressing component is installed on the transverse movement seat. The fixed end of the transverse movement driving member is installed on the base, and the driving end of the transverse movement driving member is connected to the transverse movement seat. The transverse movement driving member is configured to drive the transverse movement seat to reciprocate along the second direction, so as to drive the guiding pressing block to approach or move away from directly above the opening along the second direction.
[0012] Furthermore, the guiding wheel is set as a one-way wheel that can only rotate in one direction, so that the friction between the tape and the guiding wheel during tape feeding is less than the friction between the tape and the guiding wheel during tape rewinding.
[0013] Furthermore, a material blocking assembly is arranged on the base. The material blocking assembly is configured to press the tape against the upper roller surface of the guiding wheel to increase the friction between the tape and the guiding wheel. The material blocking assembly includes a fourth driving member and a material blocking pressing rod. The material blocking pressing rod is rotatably arranged on the base. The fixed end of the fourth driving member is installed on the base, and the driving end of the fourth driving member is connected to the first end of the material blocking pressing rod. The fourth driving member is configured to drive the material blocking pressing rod to rotate by a preset angle, so that the second end of the material blocking pressing rod abuts against the tape and presses the tape against the upper roller surface of the guiding wheel to increase the friction between the tape and the guiding wheel, thereby preventing the tape from rewinding.
[0014] Furthermore, the first driving member includes a first motor and a transverse movement member. A hinge shaft penetrates through one side of the magazine body close to the rotating member. The middle part of the rotating member abuts against the hinge shaft. The transverse movement member is connected to the second end of the rotating member. The fixed end of the first motor is installed on the magazine body, and the driving end of the first motor is connected to the transverse movement member. The first motor drives the transverse movement member to move transversely along a first direction, so as to drive the guiding wheel to approach or move away from the opening through the cooperation of the hinge shaft, thereby changing the size of the opening;
[0015] A first transmission pair is arranged between the first motor and the transverse movement member. The first transmission pair includes a first transmission lead screw and a first nut. The first transmission lead screw is rotatably arranged on the magazine body along its own axis. The first nut is fixed on the transverse movement member and sleeved on the first transmission lead screw. The driving end of the first motor is connected to the first transmission lead screw. The first motor is configured to drive the first transmission lead screw to rotate along its own axis. The first motor drives the transverse movement member to move transversely through the transmission cooperation of the first transmission lead screw and the first nut.
[0016] Furthermore, the silo body includes a feeding part and a storage part. The opening is arranged at the top of the feeding part. The width of the feeding part along the first direction is smaller than the width of the storage part along the first direction. The feeding part is located obliquely above the storage part on the side facing the guide wheel.
[0017] Furthermore, the conveying ratchet is located directly below the feeding table. The pressing component further includes a floating component. The floating component includes a floating plate, at least one buffer, and at least one floating pressing block. The first end of each buffer is connected to the lifting seat, the second end of each buffer is connected to the top of the floating plate, each floating pressing block is installed at the bottom of the floating plate, and each floating pressing block is located directly above the feeding table. The floating pressing block is configured to limit the tape on the feeding table in the height direction during feeding.
[0018] Furthermore, a sensing component is arranged on the base on one side of the feeding table. The sensing component is configured to detect whether there is a tape on the feeding table.
[0019] In a second aspect, a tape splicing machine is provided. The tape splicing machine includes the above-mentioned tape temporary storage mechanism.
[0020] Compared with the prior art, the beneficial effects of the tape temporary storage mechanism are as follows:
[0021] 1) Through the cooperation of the feeding component and the opening-adjustable silo, the first driving component drives the rotating component to rotate, drives the guide wheel to approach or move away from the opening, changes the size of the opening, and the second driving component drives the conveying ratchet to rotate to send the tape into the silo body. In the working state, the first driving component drives the guide wheel to move away from the opening to the first preset position to make the opening larger. In the waiting state, the first driving component drives the guide wheel to approach the opening to the second preset position to make the opening smaller, realizing the collection of the tape while adjusting the size of the silo opening, and avoiding congestion of the tape at the opening and creases on the tape.
[0022] 2) By setting the pressing component, the third driving component drives the guiding pressing block to the low position, and the pressing arc surface of the guiding pressing block presses the tape located at the opening, realizing accurate pressing of the tape located at the opening and ensuring the accuracy of the tape pressing position.
[0023] 3) By setting the material blocking component, the fourth driving component drives the material blocking pressing rod to rotate by a preset angle, so that the second end of the material blocking pressing rod abuts against the tape and presses the tape against the upper roller surface of the guide wheel, increasing the friction between the tape and the guide wheel and further avoiding the phenomenon of tape rewinding.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0032] In a first aspect, please refer to Figures 1 to 5As shown in the figure, in this embodiment, a tape temporary storage mechanism includes a base 10, a feeding component 20, and a magazine 30, where: The magazine 30 includes a magazine body 31, a rotating member 32, a guide wheel 33, and a first driving member 34. The magazine body 31 is fixedly arranged on the base 10. The magazine body 31 has a storage cavity for storing the tape. The opening 300 of the storage cavity faces upward and extends along the first direction ( Figure 1 the X direction in Figure 1 ), the middle part of the rotating member 32 is hinged to the magazine body 31, the first end of the rotating member 32 is located at the first end of the opening 300 in the first direction, the guide wheel 33 is installed at the first end of the rotating member 32, and the guide wheel 33 is at least configured to support and guide the tape to be stored in the storage cavity. The driving end of the first driving member 34 is connected to the second end of the rotating member 32. The first driving member 34 is configured to drive the second end of the rotating member 32 to rotate, so as to drive the guide wheel 33 to approach or move away from the opening 300, thereby changing the size of the opening 300; The feeding component 20 is arranged on the base 10 and is located on the side of the opening 300 away from the guide wheel 33. The feeding component 20 includes a feeding table 21, a conveying ratchet wheel 22, and a second driving member 23. The feeding table 21 is installed on the base 10. The feeding table 21 is configured to receive the tape on the guide wheel 33. The conveying ratchet wheel 22 is rotatably arranged on the base 10. The teeth of the conveying ratchet wheel 22 are clamped in the card holes of the tape. The driving end of the second driving member 23 is connected to the conveying ratchet wheel 22. The second driving member 23 is configured to drive the conveying ratchet wheel 22 to rotate, so as to feed the tape into the magazine body 31; In the working state, the first driving member 34 drives the guide wheel 33 to move away from the opening 300 to the first preset position, so that the opening 300 becomes larger; In the waiting state, the first driving member 34 drives the guide wheel 33 to approach the opening 300 to the second preset position, so that the opening 300 becomes smaller.
[0033] It should be noted that: A tape temporary storage mechanism needs to be used in cooperation with a material transfer mechanism (not shown in the figure). The guide wheel 33 supports and guides the tape to be stored in the storage cavity to move to the material transfer mechanism, and the material transfer mechanism then introduces the received tape to the feeding table 21. The feeding table 21 receives the introduced tape and clamps the teeth of the conveying ratchet wheel 22 in the card holes of the tape.
[0034] Specifically, the second driving member 23 is a driving motor.
[0035] It can be seen that through the cooperation of the feeding component 20 and the adjustable bin 30 with the opening 300, the first driving member 34 drives the rotating member 32 to rotate, driving the guide wheel 33 to approach or move away from the opening 300, changing the size of the opening 300. The second driving member 23 drives the conveying ratchet 22 to rotate, feeding the tape into the bin body 31. In the working state, the first driving member 34 drives the guide wheel 33 to move away from the opening 300 to a first preset position, so that the opening 300 becomes larger. In the waiting state, the first driving member 34 drives the guide wheel 33 to approach the opening 300 to a second preset position, so that the opening 300 becomes smaller. While collecting the tape, the size of the opening 300 of the bin 30 is adjusted, avoiding congestion of the tape at the opening 300 and forming creases on the tape.
[0036] As an implementation manner, a pressing component 40 is arranged on the base 10. The pressing component 40 includes a third driving member 41, a lifting seat 42 and a guiding pressing block 43. The lifting seat 42 is arranged on the base 10 in a liftable manner. The guiding pressing block 43 is installed on the lifting seat 42 and is located directly above the opening 300. The bottom of the guiding pressing block 43 has a pressing arc surface 430. The fixed end of the third driving member 41 is installed on the base 10, and the driving end of the third driving member 41 is connected to the lifting seat 42. The third driving member 41 is configured to drive the guiding pressing block 43 to rise to a high position or a low position through the lifting seat 42. The third driving member 41 drives the guiding pressing block 43 to a low position to cooperate with the pressing arc surface 430 of the guiding pressing block 43 to press the tape located at the opening 300.
[0037] Specifically, the third driving member 41 is a lifting motor. A second transmission pair is arranged between the third driving member 41 and the lifting seat 42. The second transmission pair includes a second transmission lead screw 44 and a second nut 45. The second transmission lead screw 44 is arranged on the base 10 so as to be rotatable along its own axis. The second nut 45 is fixed on the lifting seat 42 and sleeved on the second transmission lead screw 44. The driving end of the third driving member 41 is connected to the second transmission lead screw 44. The third driving member 41 is configured to drive the second transmission lead screw 44 to rotate along its own axis. The third driving member 41 drives the lifting seat 42 to move horizontally through the transmission cooperation of the second transmission lead screw 44 and the second nut 45.
[0038] It can be seen that by arranging the pressing component 40, the third driving member 41 drives the guiding pressing block 43 to a low position, and cooperates with the pressing arc surface 430 of the guiding pressing block 43 to press the tape located at the opening 300, achieving precise pressing of the tape located at the opening 300 and ensuring the accuracy of the pressing position of the tape.
[0039] As an implementation manner, a tape temporary storage mechanism further includes a transverse movement component 50. The transverse movement component 50 includes a transverse movement driving member 51 and a transverse movement seat 52. The transverse movement seat 52 can move along the second direction ( Figure 1is arranged on the base 10 close to or away from the silo body 31 in the Y direction), the pressing component 40 is installed on the transverse moving seat 52, the fixed end of the transverse moving driving part 51 is installed on the base 10, the driving end of the transverse moving driving part 51 is connected to the transverse moving seat 52, and the transverse moving driving part 51 is configured to drive the transverse moving seat 52 to reciprocate in the second direction, so as to drive the guiding pressing block 43 to approach or move away from directly above the opening 300 in the second direction.
[0040] Specifically, the transverse moving driving part 51 is a driving motor, and a third transmission pair is arranged between the transverse moving driving part 51 and the transverse moving seat 52. The third transmission pair includes a third transmission lead screw 53 and a third nut 54. The third transmission lead screw 53 is rotatably arranged on the base 10 along its own axis, the third nut 54 is fixed on the transverse moving seat 52 and sleeved on the third transmission lead screw 53, the driving end of the transverse moving driving part 51 is connected to the third transmission lead screw 53, and the transverse moving driving part 51 is configured to drive the third transmission lead screw 53 to rotate along its own axis. The transverse moving driving part 51 drives the transverse moving seat 52 to move transversely through the transmission cooperation of the third transmission lead screw 53 and the third nut 54.
[0041] It can be seen that by setting the transverse moving component 50, the transverse moving driving part 51 drives the transverse moving seat 52 to reciprocate in the second direction, driving the guiding pressing block 43 to approach or move away from directly above the opening 300 in the second direction. The transverse moving driving part 51 drives the guiding pressing block 43 to move away from directly above the opening 300, so as to create a clearance space for the guiding wheel 33 when the device is in the waiting state.
[0042] As an implementation manner, the guiding wheel 33 is set as a one-way wheel that can only rotate in one direction, so that the frictional force between the material belt and the guiding wheel 33 during belt feeding is less than the frictional force between the material belt and the guiding wheel 33 during belt rewinding.
[0043] It can be seen that by setting the guiding wheel 33 as a one-way wheel that can only rotate in one direction, when feeding the belt, the material belt moves under the rotational cooperation of the guiding wheel 33, and when rewinding the belt, the material belt moves on the upper roller surface of the fixedly arranged guiding wheel 33, which not only ensures that the material belt is fed at high speed without jamming during belt feeding, but also avoids the phenomenon of the material belt rewinding from the silo body 31.
[0044] It should be noted that when feeding the belt, the friction between the material belt and the guiding wheel 33 is rolling friction, and when rewinding the belt, the friction between the material belt and the guiding wheel 33 is sliding friction.
[0045] As an implementation manner, a material blocking assembly 60 is provided on the base 10. The material blocking assembly 60 is configured to press the material tape against the upper roller surface of the guiding wheel 33 to increase the friction force between the material tape and the guiding wheel 33. The material blocking assembly 60 includes a fourth driving member 61 and a material blocking pressing rod 62. The material blocking pressing rod 62 is rotatably arranged on the base 10. The fixed end of the fourth driving member 61 is installed on the base 10, and the driving end of the fourth driving member 61 is connected to the first end of the material blocking pressing rod 62. The fourth driving member 61 is configured to drive the material blocking pressing rod 62 to rotate a preset angle, so that the second end of the material blocking pressing rod 62 abuts against the material tape and presses the material tape against the upper roller surface of the guiding wheel 33, thereby increasing the friction force between the material tape and the guiding wheel 33 and further preventing the material tape from rewinding.
[0046] Specifically, the fourth driving member 61 is a driving motor.
[0047] It can be seen that by providing the material blocking assembly 60, the fourth driving member 61 drives the material blocking pressing rod 62 to rotate a preset angle, so that the second end of the material blocking pressing rod 62 abuts against the material tape and presses the material tape against the upper roller surface of the guiding wheel 33, increasing the friction force between the material tape and the guiding wheel 33 and further avoiding the phenomenon of the material tape rewinding.
[0048] As an implementation manner, the first driving member 34 includes a first motor 340 and a transverse moving member 341. A hinge shaft 310 is penetrated through one side of the material bin body 31 close to the rotating member 32. The middle part of the rotating member 32 abuts against the hinge shaft 310. The transverse moving member 341 is connected to the second end of the rotating member 32. The fixed end of the first motor 340 is installed on the material bin body 31, and the driving end of the first motor 340 is connected to the transverse moving member 341. The first motor 340 drives the transverse moving member 341 to move transversely in the first direction, so as to drive the guiding wheel 33 to approach or move away from the opening 300 through the cooperation of the hinge shaft 310, thereby changing the size of the opening 300. A first transmission pair is arranged between the first motor 340 and the transverse moving member 341. The first transmission pair includes a first transmission lead screw 342 and a first nut 343. The first transmission lead screw 342 is rotatably arranged on the material bin body 31 along its own axis. The first nut 343 is fixed on the transverse moving member 341 and sleeved on the first transmission lead screw 342. The driving end of the first motor 340 is connected to the first transmission lead screw 342. The first motor 340 is configured to drive the first transmission lead screw 342 to rotate along its own axis, and the first motor 340 drives the transverse moving member 341 to move transversely through the transmission cooperation of the first transmission lead screw 342 and the first nut 343.
[0049] It can be seen that by driving the traversing member 341 to traverse with the first motor 340 and driving the guide wheel 33 to move with the cooperation of the hinge shaft 310, the size of the opening 300 is changed, providing a first driving member 34 with a simple driving method and high driving stability; at the same time, through the cooperation of the first transmission lead screw 342 and the first nut 343, the first motor 340 drives the first transmission lead screw 342 to rotate along its own axis, effectively driving the traversing member 341 to traverse, providing a transmission pair with high transmission accuracy and high transmission efficiency.
[0050] As an implementation manner, the bin body 31 includes a feeding part 311 and a material storage part 312. The opening 300 is arranged at the top of the feeding part 311. The width of the feeding part 311 in the first direction is smaller than the width of the material storage part 312 in the first direction. The feeding part 311 is located obliquely above the material storage part 312 on the side facing the guide wheel 33.
[0051] It can be seen that by arranging the feeding part 311 obliquely above the material storage part 312, the material tape flows obliquely downward along the feeding part 311 into the material storage part 312 by its own weight. On the premise of realizing efficient collection of the material tape, the space at the bottom of the feeding part 311 is not occupied, making way for the movement of other subsequent devices.
[0052] As an implementation manner, the conveying ratchet 22 is located directly below the feeding table 21. The pressing component 40 further includes a floating component 70. The floating component 70 includes a floating plate 71, at least one buffer 72 and at least one floating pressing block 73. The first end of each buffer 72 is connected to the lifting seat 42, the second end of each buffer 72 is connected to the top of the floating plate 71, each floating pressing block 73 is installed at the bottom of the floating plate 71, each floating pressing block 73 is located directly above the feeding table 21, and the floating pressing block 73 is configured to limit the material tape on the feeding table 21 in the height direction during feeding.
[0053] Specifically, two buffers 72 are provided, and the two buffers 72 are arranged at intervals in the first direction. Two floating pressing blocks 73 are provided, and the two floating pressing blocks 73 are arranged at intervals in the first direction. Each floating pressing block 73 is set as a pressing wheel, and each pressing wheel is rotatably installed on the mounting plate 74. A waist-shaped hole 740 is formed in the mounting plate 74, and a screw passes through the waist-shaped hole 740 and is screwed into the floating plate 71 to adjustably set the corresponding pressing wheel on the floating plate 71 at a high position.
[0054] It can be seen that through the cooperation of the floating plate 71, the buffer 72 and the floating pressing block 73, the floating pressing block 73 limits the material tape on the feeding table 21 in the height direction during feeding, effectively avoiding the phenomenon that the material tape jumps out of the feeding table 21 during feeding.
[0055] Specifically, a blowing device 11 is provided directly above the feeding table 21. The blowing end of the blowing device 11 faces the feeding surface of the feeding table 21, and the blowing device 11 is connected to an external air supply device through an air pipe.
[0056] It can be seen that by providing the blowing device 11 with its blowing end facing the feeding surface of the feeding table 21, external miscellaneous materials are prevented from falling into the feeding table 21, achieving a clean conveying surface before and after belt feeding, further improving the feeding efficiency and avoiding wear and creases on the tape.
[0057] As an implementation manner, a sensing member 12 is provided on one side of the feeding table 21 on the base 10, and the sensing member 12 is configured to detect whether there is a tape on the feeding table 21.
[0058] Specifically, the sensing member 12 is a proximity sensor.
[0059] It can be seen that by providing the sensing member 12, it is possible to detect whether there is a tape on the feeding table 21. If no tape is detected, a prompt can be issued in a timely manner and the tape can be replenished, avoiding the idling of the conveying ratchet 22 driven by the second driving member 23.
[0060] In a second aspect, based on the above tape temporary storage mechanism, a tape receiving machine is provided, which includes the above tape temporary storage mechanism.
[0061] When the above tape temporary storage mechanism is in the working state: the first driving member 34 drives the guide wheel 33 to move away from the opening 300 to a first preset position, making the opening 300 larger. The tape to be stored in the storage cavity is sleeved on the guide wheel 33, and the guide wheel 33 supports and guides the tape to be stored in the storage cavity to move to the material transfer mechanism. The material transfer mechanism then introduces the received tape onto the feeding table 21. The feeding table 21 receives the introduced tape and engages the teeth of the conveying ratchet 22 with the tape engaging holes of the tape. The second driving member 23 drives the conveying ratchet 22 to rotate, sending the tape to the opening 300 of the bin body 31. At the same time, the third driving member 41 drives the guide pressing block 43 to the low position, and the pressing arc surface 430 of the guide pressing block 43 cooperates to press the tape located at the opening 300, pressing the tape into the storage cavity;
[0062] When the above tape temporary storage mechanism is in the waiting state: the third driving member 41 drives the guide pressing block 43 to the high position, the transverse movement driving member 51 drives the transverse movement seat 52 to move away from the base 10 along the second direction, driving the avoidance guide wheel 33 to move. The first driving member 34 drives the guide wheel 33 to move close to the opening 300 to a second preset position, making the opening 300 smaller.
[0063] It should be noted that when the strip temporary storage mechanism is in the working state, the fourth driving member 61 drives the material blocking pressure lever 62 to rotate by a preset angle, so that the second end of the material blocking pressure lever 62 presses against the guide wheel 33 and forms a material blocking area above the opening 300, and cooperates with the material blocking area to prevent the strip from jumping out of the material storage cavity when the strip is feeding.
