[0025] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0026] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are 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.

[0027] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0028] An embodiment of this utility model provides a sleeve feeding device, such as... Figure 1-4 As shown, it includes:

[0029] The storage structure 1 includes a hopper 101 for stacking and storing sleeves 4 and a feeding structure 102 disposed at the bottom of the hopper 101 for feeding sleeves 4 one by one.

[0030] The material receiving and pushing mechanism 2 includes a material receiving structure 201 disposed below the material feeding structure 102 and a first driving structure 202 for pushing the material receiving structure 201 back and forth. The material receiving structure 201 is used to receive the sleeve 4 falling from the material feeding structure 102.

[0031] The alignment mechanism 3 includes an alignment station 301 located in front of the receiving structure 201 for aligning the sleeve 4, an alignment structure 302 for aligning the sleeve 4, and a second drive structure 303.

[0032] The first drive structure 202 can push the sleeve 4 on the receiving structure 201 to the alignment station 301, and the second drive structure 303 is used to push the alignment structure 302 to the alignment station 301 from left to right, so that the alignment structure 302 abuts against and is positioned with the sleeve 4.

[0033] The storage hopper 101 in the material storage structure 1 can store a large number of sleeves 4, reducing the frequency of manual feeding. The unloading structure 102 can unload the sleeves 4 one by one, avoiding accumulation and disorder, and ensuring the accuracy of unloading. Specifically, the unloading structure 102 is located below the storage hopper 101. By using gravity or other structural forces, the sleeves 4 are moved one by one from the storage hopper 101 and fall onto the receiving structure 201. The receiving structure 201 can receive one or more sleeves 4. The first drive structure 202 can push the receiving structure 201 to the alignment station 301, so that the sleeves 4 that need to be positioned are pushed onto the alignment station 301. During the pushing of the receiving structure 201 by the first drive structure 202, the sleeves 4 in the unloading structure 102 stop being unloaded to ensure the stability of the alignment. Specifically, the unloading structure 102 can block the unloading port by using a horizontal plate, a horizontal block, or the top of the receiving structure 201 to prevent the sleeves 4 from falling further. When the sleeve 4 is pushed onto the alignment station 301, the alignment structure 302 aligns the sleeve 4 by abutting against it, ensuring the positional accuracy of the sleeve 4 during subsequent processing or assembly. The sleeve 4 is then pushed out to the alignment station 301, facilitating both alignment and direct handling by the robotic arm.

[0034] In this embodiment, the sleeve 4 rolls along the front-to-back direction to the unloading structure 102 and then is vertically unloaded. Its long side is then placed in the receiving structure 201 along the left-to-right direction and pushed to the alignment station 301. Therefore, the alignment structure 302 can be positioned on both the left and right sides, simultaneously abutting against the left and right ends of the sleeve 4 to achieve positioning, or it can be positioned on one side and pushed to abut against other abutting structures for alignment. The first drive structure 202 and the second drive structure 303 can be hydraulic cylinders, pneumatic cylinders, drive motors, or other drive structures. The arrangement of the first drive structure 202 and the second drive structure 303 ensures the stability and reliability of the pushing and alignment actions. Through the coordinated work of the storage structure 1, the receiving and pushing mechanism 2, and the alignment mechanism 3, the automatic unloading, receiving, pushing, and alignment of the sleeve 4 are achieved, reducing manual operation and improving production efficiency. The material storage structure 1 has a large capacity stacking mechanism to reduce manual intervention, and the material unloading structure 102 uses gravity or a tossing mechanism to drop the sleeves 4 one by one to avoid jamming.

[0035] In some embodiments, such as Figure 3-4 As shown, the hopper 101 includes a hopper trough 103 with a downwardly sloping bottom, and the unloading structure 102 includes a vertically downward unloading trough 104 provided at the bottom end of the hopper trough 103. The bottom of the hopper trough 103 and the rear side wall of the unloading trough 104 both have through grooves 111 with a width less than the length of the sleeve 4.

[0036] The inclined design of the hopper 103 facilitates the automatic downward sliding of the sleeve 4 to the discharge chute 104 under its own weight. The vertical downward orientation of the discharge chute 104 ensures that the sleeve 4 falls accurately onto the receiving structure 201, reducing the problem of rolling deviation caused by the inclined design. The through groove 111 is mainly designed to allow external access into the storage structure 1 to actuate the sleeve 4 if it gets stuck during sliding or falling, ensuring smooth discharge of the sleeve 4 and improving discharge efficiency and reliability.

[0037] Furthermore, such as Figure 3-4 As shown, the feeding structure 102 includes a push block 105 disposed below the hopper 103 and a third drive structure 106 for driving the push block 105 to move up and down. The push block 105 can pass through the through groove 111 and abut against the sleeve 4 on the hopper 103 to push the sleeve 4 into the feeding groove 104.

[0038] The push block 105 is controlled to move up and down by the third drive structure 106 set on the side wall of the hopper 101 or the worktable. When moving upward, the push block 105 can pass through the through groove 111 and abut against the sleeve 4 inside the storage structure 1 and push the sleeve 4 upward, ensuring that the sleeve 4 can slide smoothly into the feeding groove 104, avoiding the accumulation or jamming of the sleeve 4 during the feeding process, realizing automatic anti-jamming, reducing manual operation, and ensuring the stable operation of the entire feeding device.

[0039] Furthermore, the width of the hopper 103 is greater than the length of one sleeve 4 but less than the length of two sleeves 4, and the width of the hopper 103 is the same as that of the discharge hopper 104.

[0040] The width of the material hopper 103 can only accommodate one sleeve 4, preventing multiple sleeves 4 from being placed side by side or overlapping. This ensures that the sleeves 4 can slide into the material discharge hopper 104 one by one in an orderly manner. In practice, the width of the material hopper 103 is only slightly larger than the length of the sleeve 4, which makes it convenient to accommodate only one sleeve 4 for stable rolling and material discharge. This avoids the sleeve 4 from tilting due to excessive width, which could cause jamming or falling. This further improves the accuracy and stability of material discharge and avoids possible blockage or chaos of the sleeve 4 during the material discharge process.

[0041] Furthermore, such as Figure 1-3 As shown, the outer side of the feeding trough 104 is provided with an adjustment structure 107 for adjusting the length of the feeding trough 104 in the front-to-back direction.

[0042] To ensure accurate material feeding, the length of the feeding groove 104 in the front-to-back direction is set according to the diameter of the sleeve 4. If a sleeve 4 with a smaller diameter is replaced, the material feeding will not be accurately aligned with the receiving structure 201. The adjusting structure 107 can flexibly adjust the length of the feeding groove 104 in the front-to-back direction according to the actual diameter of the sleeve 4, thereby improving versatility and feeding stability.

[0043] Furthermore, such as Figure 2-3 As shown, the front sidewall of the feeding trough 104 has a through hole 108. The adjustment structure 107 includes an L-shaped hook 109 disposed on the front sidewall of the feeding trough 104 and an adjustment block 110 placed on the L-shaped hook 109. The adjustment block 110 is inserted into the front sidewall of the feeding trough 104.

[0044] Adjustable blocks 110 of different thicknesses can be switched to hang on L-shaped hooks 109. Specifically, the left and right sides of the adjustable block 110 have matching hook structures that can be hung on L-shaped hooks 109, the middle part is a groove that can be locked on the feeding groove 104, and the inner side is a protrusion that can extend into the feeding groove 104. The length of the feeding groove 104 in the front-to-back direction is determined by the different thicknesses of the protrusions. The structure of L-shaped hooks 109 makes it easy to switch between adjustable blocks 110 of different thicknesses, and can quickly adjust the internal dimensions of the feeding groove 104, thereby adapting to the feeding requirements of different specifications of sleeves 4, improving the versatility and flexibility of the device. At the same time, this adjustment method is simple to operate and easy to adjust quickly on site.

[0045] Furthermore, such as Figure 3 As shown, the receiving structure 201 has a receiving groove 203 directly below the feeding groove 104, and the shape of the receiving groove 203 matches the shape of the sleeve 4.

[0046] The receiving groove 203 is positioned directly below, working in conjunction with the vertically positioned discharge groove 104 to ensure that the sleeve 4 accurately falls from the discharge groove 104 into the receiving groove 203. The receiving groove 203 is square, matching the shape of the sleeve 4, and its bottom can be round, improving the stability of the receiving and ensuring the positional accuracy of the sleeve 4 during subsequent pushing and alignment processes. Furthermore, multiple receiving grooves 203 can be provided, allowing the sleeve 4 to fall into each receiving groove 203 sequentially when the first driving structure 202 drives the receiving structure 201 forward. The top of the receiving structure 201 and the bottom of the discharge groove 104 are spaced a preset distance apart to ensure that the sleeve 4 does not fall further while the receiving structure 201 is moving, and also does not obstruct sliding.

[0047] Furthermore, such as Figure 2 As shown, the second drive structure 303 is arranged side by side on the left or right side of the receiving structure 201, and the second drive structure 303 includes a connecting block 204 connected to the receiving structure 201.

[0048] Compared to the conventional rear-mounted arrangement, the side-by-side arrangement provides stable driving force while effectively saving space, ensuring that the alignment structure 302 can move accurately to the alignment station 301. The connection between the connecting block 204 and the receiving structure 201 ensures effective power transmission, making the alignment action smoother and more reliable.

[0049] Furthermore, such as Figure 1-4 As shown, the material receiving and pushing mechanism 2 also includes a guide rail 205 arranged in the front-to-back direction below the material receiving structure 201, and a guide block 206 at the bottom of the material receiving structure 201 that slides in cooperation with the guide rail 205.

[0050] The cooperation between the guide rail 205 and the guide slider 206 ensures that the receiving structure 201 maintains stable and accurate linear motion during the forward and backward movement, avoiding the problem of inaccurate position or misalignment of the sleeve 4 due to motion deviation, thus improving the operating accuracy and reliability of the entire feeding device. At the same time, this guiding structure can also withstand a certain lateral force, enhancing the stability of the sleeve 4 during alignment.

[0051] Furthermore, such as Figure 1-4 As shown, the alignment structure 302 is arranged on the opposite side of the second drive structure 303 in the left-right direction. The receiving structure 201 is provided with a limiting block 304 on the opposite side of the alignment structure 302. The second drive structure 303 can drive the alignment structure 302 to abut against the side end of the sleeve 4 and make the other side end of the sleeve 4 abut against the limiting block 304.

[0052] The cooperation between the limiting block 304 and the alignment structure 302 enables precise positioning of the sleeve 4. The limiting block 304 provides a clear positioning reference for the sleeve 4. The second drive structure 303 drives the alignment structure 302 to push the sleeve 4, making the sleeve 4 tightly abut against the limiting block 304, thereby achieving precise alignment of the sleeve 4 and facilitating subsequent handling by the robotic arm. Specifically, the alignment structure 302 can be a flat plate or a push head with a shape that matches the sleeve 4.

[0053] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
