[0002] To prevent electronic components from being contaminated or damaged during transport, carrier tape is typically used in conjunction with cover tape to protect the components. For accurate positioning and identification of the corresponding electronic components, the carrier tape needs to be laser-marked. The laser marking can be text, graphics, or QR codes.

[0003] In existing technologies, to improve laser marking efficiency, multiple tracks are typically required to perform laser marking simultaneously. When performing laser marking simultaneously on multiple tracks, the carrier belts on all tracks must be fed smoothly. Utility Model Content

[0042] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0043] The reason for the unstable feeding, as mentioned in the background technology, is mainly due to the fact that the feeding speed is not constant during laser marking, and the feeding speed of the loading tray is difficult to match perfectly with the laser marking speed. When the loading speed of the loading tray is lower than the laser marking feeding speed for a short period of time, the carrier belt will be stretched, which may even lead to deformation. Conversely, when the loading speed of the loading tray is higher than the laser marking feeding speed for a short period of time, the carrier belt will become loose, which is detrimental to ensuring the flatness of the carrier belt during marking. Especially when laser marking is performed on carrier belts on multiple tracks simultaneously, structural design is needed to ensure the stability of the carrier belt feeding.

[0044] Example 1

[0045] To solve the above problems, please refer to Figures 1 to 4 This embodiment proposes a multi-track carrier belt laser marking feeding buffer structure, including a fixed frame 1, a feeding tray 2, a buffer assembly 4, and a feeding wheel 5. Specifically, the fixed frame 1 is used to support the feeding tray 2, the buffer assembly 4, and the feeding wheel 5. The fixed frame 1 can be a plate or a box-shaped structure. The feeding tray 2, the buffer assembly 4, and the feeding wheel 5 are all disposed on the outer wall of the box-shaped structure.

[0046] Specifically, the feeding tray 2 is mounted on the fixed frame 1, and the feeding tray 2 and the fixed frame 1 are rotatably connected; the axis of the feeding tray 2 is basically horizontal, and it is preferred to be arranged horizontally. In practical applications, it is preferable that the feeding speed of the feeding tray 2 is controllable. Controlling the feeding speed of the feeding tray 2 is a conventional technical means for those skilled in the art, and will not be described in detail here.

[0047] For structures where multiple carrier tapes are laser-marked simultaneously, the carrier tapes should be arranged horizontally on the same horizontal plane during marking. Therefore, it is best if the center lines of each carrier tape along its length are roughly in the same vertical plane. That is, the distance between the same carrier tape and the fixing frame 1 should be roughly equal, while the distances between different carrier tapes and the fixing frame 1 should be unequal.

[0048] The function of buffer component 4 is to provide a certain buffering range for each carrier tape. The presence of buffer component 4 ensures that each carrier tape adapts to the feeding requirements of the laser marking equipment, preventing the carrier tape from being too tight or too loose between the feeding tray and the laser marking equipment, thus ensuring a smoother feeding process. In practical applications, each carrier tape corresponds to one buffer structure.

[0049] To supply the carrier belt to the laser marking equipment at a suitable position, multiple feeding rollers 5 are also provided. The multiple feeding rollers 5 are all rotatably mounted on the fixed frame 1. The number of feeding rollers 5 is equal to the number of feeding trays 2 and corresponds one-to-one. That is, each carrier belt corresponds to one feeding roller 5. The function of the feeding rollers 5 is to adjust the corresponding carrier belt to a suitable distance from the fixed frame 1, so that in the laser marking equipment, only the vertical distance of each carrier belt needs to be adjusted, avoiding large adjustments to the horizontal position of the carrier belt.

[0050] The carrier belt 3 on each of the feeding trays 2 sequentially passes around the corresponding buffer assembly 4 and the corresponding feed roller 5. In this way, the buffer assembly 4 is used to adjust the carrier belt to prevent it from being too loose or too tight, thus ensuring that the carrier belt 3 feeds smoothly.

[0051] In some implementations, the buffer component 4 can be formed in various ways. For example, some structures use springs for tensioning. However, the elastic force generated by the spring is related to the amount of spring deformation. When the compression or tension of the spring is different, the carrier belt is subjected to uneven force along its length. Therefore, the buffer component designed in this disclosure is specifically as follows:

[0052] Please refer to Figures 1 to 4 The buffer assembly 4 includes a slide rail 41 fixedly mounted on the fixed frame 1, a slider 42 slidably mounted on the slide rail 41, and a first adjusting wheel 43 rotatably mounted on the slider 42. In a specific implementation, the slide rail 41 and slider 42 are slidably connected, and the slider 42 can only slide along the length of the slide rail 41; its freedom in other directions is restricted. Specifically, the groove that fits the slider 42 with the slide rail 41 can be a T-shaped groove or a dovetail groove to prevent the slider 42 from disengaging from the slide rail 41; that is, the cross-section of the slide rail 41 can be a T-shaped structure. In a preferred embodiment, the slide rail 41 is vertically mounted, and the carrier belt 3 passes around the first adjusting wheel 43 on the corresponding slider 42. The tension of the carrier belt is adjusted using the gravity of the slider 42. Since the gravity of the slider 42 remains constant, the tension along the length of the carrier belt can be kept essentially constant. When the feeding speed of the laser marking equipment exceeds the feeding speed of the feeding tray for a short period, the carrier belt tightens and the slider 42 moves upward to eliminate the tension caused by the speed difference between the laser marking equipment and the feeding tray. When the feeding speed of the laser marking equipment is less than the feeding speed of the feeding tray for a short period, the carrier belt loosens and the slider 42 moves downward under its own gravity to eliminate the loosening of the carrier belt caused by the speed difference between the laser marking equipment and the feeding tray. Compared to feeding devices without a feeding buffer structure, this device can automatically adapt to the feeding speed requirements of the laser marking equipment, eliminating the need for the feeding speed of the feeding tray to be completely consistent with the feeding speed of the laser marking equipment, which is also difficult to achieve.

[0053] In practical implementation, the rotation center line of the first adjusting wheel 43 is perpendicular to the length direction of the slide rail 41. This facilitates movement under the action of the carrier belt. In other words, by setting the first adjusting wheel 43 and making the carrier belt pass around it, a force can be applied along the length direction of the corresponding carrier belt using the gravity of the slider 42 and the first adjusting wheel 43. Combined with the sliding of the slider 42, the tension of the carrier belt can be adjusted to ensure smooth feeding.

[0054] In some implementations, due to structural limitations, the sliding distance of slider 42 should generally not be too large. Therefore, the sliding distance of slider 42 can be limited to a certain range. Specifically, the sliding of slider 42 can be limited by a first limiting block 411 and a second limiting block 412, thus allowing slider 42 to slide between the first limiting block 411 and the second limiting block 412. Specifically, the first limiting block 411 and the second limiting block 412 are configured as follows: a first limiting block 411 and a second limiting block 412 are fixedly provided on the slide rail 41; the first limiting block 411 and the second limiting block 412 are respectively disposed at both ends of the slide rail 41; the slider 42 can slide between the first limiting block 411 and the second limiting block 412. For example, in some implementations, the distance between the first limiting block 411 and the second limiting block 412 can be 0.5 to 1.5 meters. When the slide rail 41 is set vertically, the first limiting block 411 is set at the upper end of the slide rail 41, and the second limiting block 412 is set at the lower end of the slide rail 41.

[0055] While the above structure can achieve stable feeding, in extreme cases, if the carrier belt continues to tighten when the slider 42 moves upward against the first limiting block 411, the buffer structure will lose its function; or if the carrier belt continues to loosen when the slider 42 moves downward against the second limiting block 412, the buffer structure will also lose its function. Therefore, in some implementations, proximity sensors are added. Specifically, a first proximity sensor and a second proximity sensor are installed on each slide rail 41, located between the first limiting block 411 and the second limiting block 412. The first proximity sensor is located closer to the first limiting block 411, and the second proximity sensor is located closer to the second limiting block 412. By setting the first and second proximity sensors, the feeding speed of the corresponding feeding tray can be easily controlled based on the signals from the first and second proximity sensors, ensuring that the slider 42 always operates between the first and second limiting blocks 411 and 412. Adjusting the feeding speed of the corresponding feeding tray based on the signals from the first and second proximity sensors is a conventional technique that those skilled in the art can understand and implement, and will not be elaborated further here.

[0056] In practical applications, to reduce interference with other components and minimize space occupation, in this embodiment, the fixing frame 1 is further provided with a second adjusting wheel 44 and a third adjusting wheel 45; specifically, the second adjusting wheel 44 and the third adjusting wheel 45 are rotatably connected to the fixing frame 1. The second adjusting wheel 44 and the third adjusting wheel 45 are disposed on both sides of one end of the slide rail 41; when the slide rail 41 is vertically arranged, the second adjusting wheel 44 and the third adjusting wheel 45 are respectively located on both sides of the upper end of the slide rail 41. The carrier belt 3 passes sequentially around the second adjusting wheel 44, the first adjusting wheel 43, and the third adjusting wheel 45.

[0057] In the laser marking process, it is usually necessary to mark carrier tapes of different widths. Therefore, to accommodate different widths, the first adjusting wheel 43, the second adjusting wheel 44, the third adjusting wheel 45, and the feed wheel 5 have all been further improved: the first adjusting wheel 43, the second adjusting wheel 44, the third adjusting wheel 45, and the feed wheel 5 all include a wheel axle 51 and a wheel body 52; the wheel axle 51 is fixedly installed with the fixed frame 1, and the wheel body 52 is rotatably installed on the wheel axle 51; the wheel body 52 has multiple annular grooves 53 in the middle for accommodating carrier tapes 3 of different widths. Specifically, the smaller the width, the greater the depth of the corresponding annular groove 53. In specific implementation, the number of first adjusting wheels 43 can be one or two. When there is one first adjusting wheel 43, it should be located in the middle position of the slider 42. If there are two first adjusting wheels 43, they should be symmetrically arranged about the slide rail 41.

[0058] In practical implementation, to facilitate adjustment of the discharge position of the carrier belt on different tracks, this disclosure also includes multiple adjusting wheels 6, with each feeding tray 2 corresponding to at least one adjusting wheel 6; the portion of the carrier belt 3 located between the corresponding buffer assembly 4 and the corresponding feeding wheel 5 bypasses the corresponding adjusting wheel 6. The adjusting wheel 6 has multiple annular grooves 53 for accommodating carrier belts of varying widths 3. By providing multiple adjusting wheels 6 and annular grooves 53 on the adjusting wheels 6, it is beneficial to maintain the stability of the carrier belt's position along the axial direction of the adjusting wheel 6.
