Description

Technical Field

[0001] This utility model belongs to the field of automatic tape feeding technology for chip mounters, and in particular relates to an adjustable tape storage bin and tape feeding machine. Background Technology

[0002] SMT (Surface Mount Technology) is a core technology in modern electronics manufacturing and is widely used in consumer electronics, communication equipment, automotive electronics and other fields. The core equipment of SMT technology is the SMT placement machine, which can automatically pick up components and place them accurately on the PCB through an electronic eye recognition device.

[0003] Typically, when the tape in the pick-and-place machine is about to run out, a tape feeder is needed to connect the head of the new tape reel to the tail of the old tape reel. After connection, the new tape reel is placed at the preset station of the pick-and-place machine. Therefore, most tape feeders are usually equipped with a buffer bin to temporarily store the tape from the old tape reel. The buffer bin can be fixed or rotary. Fixed buffer bins usually have a longer feed inlet to avoid tape congestion at the feed inlet, which results in a larger space occupied by the feed part of the buffer bin and a larger overall machine size. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable feeder for temporary storage of feed strips and a feeder for receiving feed strips, so as to solve the problem of large space occupation of buffer bins in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] In a first aspect, an adjustable feed spout temporary storage bin is provided, comprising a bin body, guide wheels, a rotating component, and a first driving component, wherein:

[0007] The hopper body is fixedly mounted on the machine platform. The hopper body has a storage cavity for storing material strips. The opening of the storage cavity faces upward and has a horizontal section extending along a first direction.

[0008] The middle part of the rotating component is hinged to the hopper body, the first end of the rotating component 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 component, and the guide wheel is at least configured to support and guide the material belt to be stored in the storage cavity;

[0009] The fixed end of the first driving member is mounted on the hopper body, and 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, thereby causing the guide wheel to rotate closer to or further away from the second end of the opening in the first direction, thereby changing the size of the opening.

[0010] The material strip is introduced into the storage cavity from the second end of the opening in the first direction via the guide wheel.

[0011] Furthermore, the second end of the rotating component extends into the storage cavity, the first end of the rotating component extends out of the opening at the first end in the first direction, and the width of the rotating component is adapted to the width of the storage cavity.

[0012] Furthermore, the guide wheel is configured as a one-way wheel that can only rotate in one direction, so that the friction between the material belt and the guide wheel when the belt is being fed is less than the friction between the material belt and the guide wheel when the belt is being retracted.

[0013] Furthermore, the hopper body includes a feeding section and a storage section. The opening is located at the top of the feeding section. The width of the feeding section along the first direction is smaller than the width of the storage section along the first direction. The feeding section is located diagonally above the storage section on the side facing the guide wheel.

[0014] Furthermore, the hopper body includes a first baffle, a second baffle, and a first side plate, wherein:

[0015] The first baffle and the second baffle are arranged in parallel and spaced apart and connected as a whole by multiple connectors. The first side plate is disposed between the outer edge of the first baffle and the outer edge of the second baffle. The first baffle, the second baffle and the first side plate form the storage cavity.

[0016] A hinge shaft is installed between the first baffle and the second baffle, and the middle part of the rotating member is rotatably sleeved on the hinge shaft.

[0017] Furthermore, the first side plate of the hopper body near the guide wheel is provided with a gap, which is located above the hinge shaft, so that a space for the rotating component to rotate is formed obliquely above the hopper body.

[0018] Furthermore, a limiting member is provided at the upper part of the vacant portion, and the rotating member is disposed inside the limiting member. The limiting member is configured to limit the travel of the rotating member away from the opening. The first end of the limiting member is connected to the inner wall of the first baffle, and the second end of the limiting member is connected to the inner wall of the second baffle.

[0019] Furthermore, the first driving component includes a first motor and a lateral moving component. The lateral moving component is connected to the second end of the rotating component. The fixed end of the first motor is mounted on the first baffle. The driving end of the first motor is connected to the lateral moving component. The first motor drives the lateral moving component to move laterally in a first direction, so as to drive the guide wheel to move closer to or away from the opening through the cooperation of the hinge shaft, thereby changing the size of the opening.

[0020] Furthermore, a transmission pair is provided between the first motor and the transverse member. The transmission pair includes a transmission screw and a nut. The transmission screw is rotatably mounted on the first baffle along its own axis. The nut is fixed on the transverse member and sleeved on the transmission screw. The driving end of the first driving member is connected to the transmission screw. The first driving member is configured to drive the transmission screw to rotate along its own axis. The first driving member drives the transverse member to move laterally through the transmission cooperation of the transmission screw and the nut.

[0021] In one aspect, a material strip receiving machine is provided, which includes the aforementioned adjustable material strip temporary storage bin.

[0022] Compared with the prior art, the advantages of the adjustable feed spout temporary storage bin and feed spout receiving machine are as follows:

[0023] 1) Through the cooperation of the guide wheel, the rotating part and the first driving part, the guide wheel supports the material belt to be stored in the storage cavity. The first driving part drives the second end of the rotating part to rotate, which drives the guide wheel to move closer to or away from the opening, thereby changing the size of the opening. This realizes the adjustment of the size of the opening. When feeding, the first driving part drives the guide wheel away from the second end of the opening in the first direction, making the opening larger. The material belt is introduced into the storage cavity from the opening through the guide wheel, avoiding the material belt from being blocked at the feed port. When not feeding, the first driving part drives the guide wheel closer to the second end of the opening in the first direction, making the opening smaller, which significantly reduces the space occupied by the temporary storage bin.

[0024] 2) By setting the guide wheel to be a unidirectional wheel that can only rotate in one direction, the material belt moves under the rotation of the guide wheel during feeding and moves on the upper roller surface of the fixed guide wheel during rewinding. This ensures that the material belt is fed at high speed without jamming during feeding and prevents the material belt from jumping out of the hopper body during rewinding.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Firstly, please refer to Figures 1 to 3As shown, in this embodiment, an adjustable feed tray storage bin includes a bin body 10, a guide wheel 20, a rotating component 30, and a first driving component 40. The bin body 10 is fixedly mounted on a machine base (not shown in the figure). The bin body 10 has a storage cavity for storing the feed tray, with the opening 100 of the storage cavity facing upwards and having a direction along a first direction (…). Figure 1 The horizontal segment extending in the X direction; the middle part of the rotating member 30 is hinged to the hopper body 10, the first end of the rotating member 30 is located at the first end of the opening 100 in the first direction, the guide wheel 20 is installed at the first end of the rotating member 30, and the guide wheel 20 is configured to support and guide the material belt to be stored in the storage cavity; the fixed end of the first driving member 40 is installed on the hopper body 10, the driving end of the first driving member 40 is connected to the second end of the rotating member 30, and the first driving member 40 is configured to drive the second end of the rotating member 30 to rotate, so as to drive the guide wheel 20 to rotate closer to or away from the second end of the opening 100 in the first direction, thereby changing the size of the opening 100; the material belt is introduced into the storage cavity from the second end of the opening 100 in the first direction via the guide wheel 20.

[0032] As can be seen, through the cooperation of the guide wheel 20, the rotating part 30 and the first driving part 40, the guide wheel 20 supports the material belt to be stored in the storage cavity, and the first driving part 40 drives the second end of the rotating part 30 to rotate, causing the guide wheel 20 to move closer to or away from the opening 100, thereby changing the size of the opening 100 and realizing the adjustment of the size of the opening 100. When feeding, the first driving part 40 drives the guide wheel 20 away from the second end of the opening 100 in the first direction, making the opening 100 larger, and the material belt is introduced into the storage cavity from the opening 100 through the guide wheel 20, avoiding the material belt from being blocked at the feeding port. When not feeding, the first driving part 40 drives the guide wheel 20 closer to the second end of the opening 100 in the first direction, making the opening 100 smaller, which significantly reduces the space occupied by the temporary storage bin.

[0033] In one embodiment, the second end of the rotating member 30 extends into the storage cavity, and the first end of the rotating member 30 extends out of the opening 100 at the first end in the first direction. The width of the rotating member 30 is adapted to the width of the storage cavity.

[0034] It can be seen that by setting the second end of the rotating part 30 inside the storage cavity, not only can the rotation of the rotating part 30 be adjusted, but the external space of the storage cavity is not occupied, further reducing the space occupied by the temporary storage bin.

[0035] In one implementation, the guide wheel 20 is configured as a one-way wheel that can only rotate in one direction, so that the friction between the belt and the guide wheel 20 when the belt is being fed is less than the friction between the belt and the guide wheel 20 when the belt is being retracted.

[0036] It can be seen that by setting the guide wheel 20 as a unidirectional wheel that can only rotate in one direction, the material belt moves under the rotation of the guide wheel 20 during feeding and moves on the upper roller surface of the fixed guide wheel 20 during rewinding. This ensures that the material belt is fed at high speed without jamming during feeding and prevents the material belt from jumping out of the hopper body 10 during rewinding.

[0037] It should be noted that the friction between the belt and the guide wheel 20 is rolling friction when the belt is being fed, and sliding friction when the belt is being rewound.

[0038] In one embodiment, the hopper body 10 includes a feeding section 11 and a storage section 12. An opening 100 is provided at the top of the feeding section 11. The width of the feeding section 11 along the first direction is smaller than the width of the storage section 12 along the first direction. The feeding section 11 is located obliquely above the storage section 12 on the side facing the guide wheel 20.

[0039] As can be seen, by setting the feeding section 11 diagonally above the storage section 12, the material belt flows diagonally downward into the storage section 12 by its own weight. Under the premise of achieving efficient collection of the material belt, it does not occupy the space at the bottom of the feeding section 11, thus making way for the movement of other equipment.

[0040] In one embodiment, the hopper body 10 includes a first baffle 13, a second baffle 14, and a first side plate 15, wherein: the first baffle 13 and the second baffle 14 are along a second direction ( Figure 1 The components (in the Y direction) are arranged in parallel intervals and connected as a whole by multiple connectors 16. The first side plate 15 is located between the outer edge of the first baffle 13 and the outer edge of the second baffle 14. The first baffle 13, the second baffle 14 and the first side plate 15 form a storage cavity. A hinge shaft 17 is installed between the first baffle 13 and the second baffle 14. The middle part of the rotating component 30 is rotatably sleeved on the hinge shaft 17.

[0041] Specifically, the middle part of the rotating component 30 can also be hinged between the first baffle 13 and the second baffle 14.

[0042] As can be seen, the first baffle 13, the second baffle 14 and the first side plate 15 are connected into one body by multiple connectors 16, providing a hopper body 10 with a simple structure and easy installation. At the same time, a hinge shaft 17 is installed between the first baffle 13 and the second baffle 14, which does not occupy the external space of the hopper body 10.

[0043] In one embodiment, the first side plate 15 of the hopper body 10 near the guide wheel 20 is provided with a gap, which is located above the hinge shaft 17, so that a space for the rotating member 30 to rotate is formed obliquely above the hopper body 10.

[0044] It can be seen that by providing a gap on the side of the hopper body 10 near the guide wheel 20, interference between the rotating part 30 and the hopper body 10 is avoided when rotating, and at the same time, feeding space is provided for the material belt to flow into the storage cavity.

[0045] In one embodiment, a limiting member 18 is provided on the upper part of the vacant portion, and a rotating member 30 is provided inside the limiting member 18. The limiting member 18 is configured to limit the travel of the rotating member 30 away from the opening 100. The first end of the limiting member 18 is connected to the inner wall of the first baffle 13, and the second end of the limiting member 18 is connected to the inner wall of the second baffle 14.

[0046] It can be seen that by setting the limiting component 18, the travel of the rotating component 30 away from the opening 100 is limited, so as to avoid the overall space occupied by the equipment being too large due to the opening 100 being too large.

[0047] It should be noted that: on the one hand, when the first baffle 13 and the second baffle 14 are assembled, the limiting member 18 can serve as a connecting member to connect the first baffle 13 and the second baffle 14 into one unit; on the other hand, when the rotating member 30 rotates, the limiting member 18 can also serve as a limiting member to limit the travel of the rotating member 30 away from the opening 100.

[0048] In one embodiment, the first driving member 40 includes a first motor 41 and a transverse member 42. The transverse member 42 is connected to the second end of the rotating member 30. The fixed end of the first motor 41 is mounted on the first baffle 13. The driving end of the first motor 41 is connected to the transverse member 42. The first motor 41 drives the transverse member 42 to move laterally in a first direction, so as to drive the guide wheel 20 to move closer to or away from the opening 100 through the cooperation of the hinge shaft 17, thereby changing the size of the opening 100.

[0049] Specifically, a mounting bracket 50 is installed on one side of the first baffle 13 along the second direction, and the first motor 41 is mounted on the first baffle 13 through the mounting bracket 50.

[0050] As can be seen, the first motor 41 drives the transverse component 42 to move laterally, and with the cooperation of the hinge shaft 17, it drives the guide wheel 20 to move, thereby changing the size of the opening 100, thus providing a first driving component 40 with a simple driving method and high driving stability.

[0051] In one embodiment, a transmission pair is provided between the first motor 41 and the transverse member 42. The transmission pair includes a transmission screw 43 and a nut 44. The transmission screw 43 is rotatably mounted on the first baffle 13 along its own axis. The nut 44 is fixed on the transverse member 42 and sleeved on the transmission screw 43. The driving end of the first driving member 40 is connected to the transmission screw 43. The first driving member 40 is configured to drive the transmission screw 43 to rotate along its own axis. The first driving member 40 drives the transverse member 42 to move laterally through the transmission cooperation of the transmission screw 43 and the nut 44.

[0052] As can be seen, through the cooperation of the transmission screw 43 and the nut 44, the first driving member 40 drives the transmission screw 43 to rotate along its own axis, effectively driving the transverse member 42 to move laterally, providing a transmission pair with high transmission accuracy and high transmission efficiency.

[0053] Secondly, based on the aforementioned adjustable material outlet temporary storage bin, a material strip receiving machine is provided, including the aforementioned adjustable material outlet temporary storage bin.

[0054] When the above-mentioned adjustable material tray storage bin is feeding the material: the first driving member 40 drives the second end of the rotating member 30 to rotate, which drives the guide wheel 20 to rotate away from the second end of the opening 100 in the first direction until the rotating member 30 abuts against the limiting member 18. At this time, the opening 100 reaches its maximum size, and the material tray is introduced into the storage cavity from the second end of the opening 100 in the first direction under the rotation of the guide wheel 20, thus completing the feeding.

[0055] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
