Description

Technical Field

[0001] This utility model belongs to the field of material feeding technology, specifically referring to a packaged chip roll feeding device. Background Technology

[0002] During the chip packaging and testing process, the reels are fed via a winding conveyor. During testing, the operator needs to load the reel onto the equipment's feeding end and unroll the strip for testing. After each reel is tested, it needs to be reloaded.

[0003] Currently, two main feeding methods are used: manual feeding and pneumatic feeding. While manual feeding is simple to operate, it is inefficient and has high labor costs. Pneumatic feeding, on the other hand, improves efficiency but also has significant drawbacks: due to automated feeding, the feeding frequency is high, placing strict requirements on the stability and durability of the pneumatic mechanism; it also relies on high-precision sensors for positioning and anomaly monitoring, increasing system complexity and the false alarm rate; furthermore, issues such as air pressure fluctuations, mechanical wear, and decreased sensor sensitivity in the pneumatic system all affect the reliability of feeding and increase equipment maintenance costs. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a packaged chip roll feeding device, which at least partially solves the above problems.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a chip roll feeding device, including a conveying cylinder, which is configured to be tilted and fixed for holding the roll;

[0006] A rotating shaft is horizontally positioned below the conveying cylinder and is driven to rotate by a motor. The rotating shaft has trapezoidal grooves arranged in a circular array.

[0007] The transfer tray, hinged in a trapezoidal groove, is used to receive and fix the material roll;

[0008] A cam disk is fixedly sleeved on a rotating shaft, and the cam disk is provided with a protrusion.

[0009] Furthermore, the protrusion is located in the upper circumferential region of the rotating shaft, and the arc length of the protrusion is greater than the width of the trapezoidal groove. The arc length of the area on the cam disk where the protrusion is located is greater than the width of the trapezoidal groove.

[0010] Furthermore, the end of the trapezoidal groove away from the conveying cylinder is set as an inclined side, and the contour of the protrusion is adapted to the angle of the inclined side.

[0011] Furthermore, the transfer plate is provided with a first positioning pin, the feed plate is provided below the rotating shaft, and the feed plate is provided with a second positioning pin. The first positioning pin and the second positioning pin are the same size.

[0012] Furthermore, the first positioning pin and the second positioning pin are coaxially aligned, and their ends are in contact with each other.

[0013] Furthermore, push rods are symmetrically arranged on both sides below the rotating shaft, and the push rods are used to push the material roll onto the feeding tray.

[0014] The beneficial effects of this utility model are as follows: This solution uses a motor to drive the rotating shaft to rotate. During the rotation of the shaft, the angle of the transfer plate is controlled by the cam plate to achieve material feeding. This device is different from pneumatic drive and uses a motor screw drive, which has better stability. Moreover, the conveyor cylinder can load multiple rolls of material at one time. The rolls are automatically positioned under the action of gravity, realizing continuous material feeding, greatly reducing the frequency of manual intervention, and effectively improving production efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1-4 As shown in the figure, an embodiment of the present invention proposes a chip roll loading device, including a conveying cylinder 1, a rotating shaft 2, a transfer disk 3, and a cam disk 4. The conveying cylinder 1 is fixedly inclined, and the chip rolls are uniformly placed in the conveying cylinder 1. The chip rolls will automatically slide down under the action of gravity. The rotating shaft 2 is horizontally located below the conveying cylinder 1. The rotating shaft 2 is driven to rotate by a motor 7. The stability and accuracy of the motor 7 are superior to those of pneumatic components. The rotating shaft 2 is provided with trapezoidal grooves 10 arranged in a circumferential array. In some embodiments, two sets of trapezoidal grooves 10 are provided. The transfer disk 3 is hinged in the trapezoidal grooves 10, from which... All material rolls sliding down the conveyor cylinder 1 are caught and fixed by the transfer plate 3; the cam plate 4 is fixedly sleeved on the rotating shaft 2. The cam plate 4 does not rotate with the rotating shaft 2. The cam plate 4 is provided with a protrusion 11. When the transfer plate 3 contacts the protrusion 11, it will change its angle to match the tilt angle of the conveyor cylinder 1 so as to catch the material rolls sliding down the conveyor cylinder 1. When the transfer plate 3 rotates with the rotating shaft 2 to the area below that is not the protrusion 11, the transfer plate 3 will naturally droop under the action of gravity and remain in a vertical state, so as to facilitate the subsequent conveying of the material rolls on the transfer plate 3 to the feeding end of the testing equipment.

[0024] In some embodiments, the protrusion 11 is located in the upper circumferential region of the rotating shaft 2. The arc length of the protrusion 11 is greater than the width of the trapezoidal groove 10, thereby ensuring that the transfer disk 3, which rotates with the trapezoidal groove 10 to the top, can tilt to a suitable angle under the action of the protrusion 11 so that the transfer disk 3 can dock with the conveying cylinder 1. The arc length of the area on the cam disk 4 that is not where the protrusion 11 is located is greater than the width of the trapezoidal groove 10, thereby ensuring that the transfer disk 3, which rotates with the trapezoidal groove 10 to the top and bottom, is not affected by the protrusion 11, so that the transfer disk 3 hangs down naturally under the action of gravity so as to dock with the detection equipment.

[0025] In some embodiments, the end of the trapezoidal groove 10 away from the conveying cylinder 1 is set as an inclined side. When the transfer disk 3, which is hinged in the trapezoidal groove 10, is pressed, it will only move in the direction of the inclined side, thereby ensuring that the angle is adapted to the conveying cylinder 1. The contour of the protrusion 11 is adapted to the angle of the inclined side, that is, the contour angle of the protrusion 11 can drive the transfer disk 3 to press against the inclined side, avoiding the situation where the pressing angle is too large or too small.

[0026] In some embodiments, the transfer disk 3 is provided with a first positioning pin 8. When the transfer disk 3 is coaxial with the conveying cylinder 1, the first positioning pin 8 is located on the central axis of the conveying cylinder 1. The center of the material roll sliding down the conveying cylinder 1 can directly slide onto the first positioning pin 8. The size of the first positioning pin 8 is adapted to the aperture of the center of the material roll. A feeding disk 6 is provided below the rotating shaft 2. The feeding disk 6 supplies material to the detection device. A second positioning pin 9 is provided on the feeding disk 6. The first positioning pin 8 and the second positioning pin 9 are the same size. The first positioning pin 8 and the second positioning pin 9 are coaxially aligned and their ends are in contact with each other, thereby ensuring that the material roll on the first positioning pin 8 can directly slide onto the second positioning pin 9.

[0027] In some embodiments, push rods 5 are symmetrically arranged on both sides below the rotating shaft 2. The push rods 5 can be driven to extend and retract by a more reliable electric screw. When the transfer plate 3 moves the material roll to the lower position, the electric screw drives the push rods 5 to move towards the transfer plate 3 and pushes the material roll on the transfer plate 3 towards the feeding plate 6, so that the material roll slides from the first positioning pin 8 to the second positioning pin 9, thereby completing the feeding operation.

[0028] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
