Description

Technical Field

[0001] This utility model belongs to the field of mechanical installation technology, specifically relating to a three-dimensional adjustment device for installing scanners on automated production lines. Background Technology

[0002] On automated packaging production lines, barcode scanners are needed to scan and identify packing slips on pallets for information management. Currently, barcode scanners are mainly installed as fixed units on the automated packaging line or as adjustable units using a screw mechanism. However, these installation methods only allow for positional adjustment in a single dimension (such as the vertical direction) and cannot adjust horizontal displacement. When the type of pallet changes (accompanied by changes in the packing slip placement and / or size), the barcode scanner struggles to adapt to scanning packing slips for different pallet sizes, resulting in low scanning efficiency or even scanning failures, severely impacting the smooth operation of the automated packaging line.

[0003] To address the issue of traditional adjustable supports having only one adjustment dimension, several improvements have emerged in existing technologies. For example, Chinese utility model patent application number 201822134428.1 discloses a three-dimensional adjustable support made entirely of aluminum profiles, comprising a base, a column, a first adjustment component, a second adjustment component, and a mounting platform. This support uses a rotating knob to control the vertical movement of the feet to achieve base positioning. The first adjustment component is used for vertical adjustment, the second adjustment component for horizontal adjustment, and the mounting platform is rotatable. This design, to a certain extent, improves upon the problems of traditional supports, such as bulky appearance, cumbersome operation, time-consuming adjustment, and high cost.

[0004] However, although the aforementioned existing technologies have achieved three-dimensional adjustment, they still have significant shortcomings for the specific application scenarios of pallet and box list scanning in automated packaging lines:

[0005] Its bulky appearance and complex structure: the base design does not fully consider the compact space layout requirements of automated packaging lines, the components are large in size, and after installation, they are prone to spatial interference with other equipment on the packaging line. Both the first adjustment component and the second adjustment component have complex structures, making production and assembly relatively complicated.

[0006] The operation is cumbersome and the adjustment is time-consuming: the first and second adjustment components can only achieve vertical adjustment, and the operation is cumbersome; if front-back and left-right adjustment is to be achieved, the entire three-dimensional adjustment bracket needs to be moved, which is time-consuming, laborious, and difficult to adjust accurately.

[0007] High cost: The use of an all-aluminum profile structure and multiple sets of mechanical adjustment components results in high material and processing costs, which is not conducive to large-scale promotion and application.

[0008] In summary, existing barcode scanner mounting brackets cannot meet the needs of automated packaging lines for efficient and flexible adjustment of pallet, box, and packing slip scanning. There is an urgent need for a barcode scanner mounting bracket that can achieve multi-dimensional precise adjustment, has a compact and elegant structure, is easy to operate, and is cost-effective. Utility Model Content

[0009] The purpose of this invention is to propose a three-dimensional adjustment device for scanner installation on an automated production line. It features multi-dimensional precise adjustment, a compact and elegant structure, convenient operation, and controllable cost, thus meeting the efficient and flexible adjustment requirements of automated packaging lines for scanning pallets, boxes, and packing lists.

[0010] The above objectives are achieved through the following technical solutions:

[0011] A three-dimensional adjustment device for mounting a scanner on an automated production line includes a vertical guide column, a longitudinal guide assembly, a transverse guide beam, and an equipment mounting base. The longitudinal guide assembly is vertically slidably connected to the vertical guide column via a first fastener and a first guide structure. The transverse guide beam is vertically slidably connected to the longitudinal guide assembly via a second fastener and a second guide structure. The equipment mounting base is laterally slidably connected to the transverse guide beam via a third guide structure and is used to mount the scanner equipment.

[0012] Preferably, the longitudinal guide assembly includes a longitudinal guide beam and a right-angle tripod; the longitudinal guide beam is connected to one right-angle side of the right-angle tripod, and the other right-angle side of the right-angle tripod is fitted to the vertical guide column.

[0013] Preferably, the first guide structure is a vertical guide hole; the vertical guide hole is radially through the vertical guide post and extends axially along the vertical guide post; the first fastener passes radially through the vertical guide hole along the vertical guide post and is then connected to the longitudinal guide assembly.

[0014] Preferably, the first fastener includes a first screw and a first nut; one end of the first screw is fixedly connected to the longitudinal guide assembly; the other end of the first screw radially penetrates the vertical guide post through the vertical guide hole and is threadedly adjustablely connected to the first nut.

[0015] Preferably, the first nut is provided with an extension auxiliary operating rod.

[0016] Preferably, the second guide structure includes a longitudinal linear guide groove disposed on the longitudinal guide assembly, the second fastener includes a second screw and a second nut, the second nut and the second screw being threadedly adjustable; one end of the second screw is fixed with a slider I, and the slider I is slidably engaged with the longitudinal linear guide groove; the other end of the second screw is connected to the transverse guide beam.

[0017] Preferably, the second guide structure further includes a transverse linear guide groove I disposed on the transverse guide beam; the second fastener further includes a third nut, which is threadedly and adjustablely connected to the second screw; a slider II is fixed to one end of the second screw connected to the transverse guide beam, and the slider II is slidably engaged with the transverse linear guide groove I.

[0018] Preferably, the second nut and the third nut are each provided with an extension auxiliary operating lever.

[0019] Preferably, the third guide structure includes a transverse linear guide groove II disposed on a transverse guide beam and a slider III fixed on a device mounting base, wherein the device mounting base is slidably engaged with the transverse linear guide groove II via the slider III.

[0020] This technical solution has the following beneficial effects:

[0021] 1. Compact and elegant structure, adaptable to the space requirements of automated production lines. Simplified component design: Utilizing a combination of right-angle tripods, vertical guide columns, longitudinal guide beams, and transverse guide beams, it replaces the bulky all-aluminum profile base and complex adjustment components of existing technologies. The overall shape is smaller, reducing spatial interference with other equipment on the packaging line and fitting into compact automated production line layouts. Modular integration: Through the cooperation of guide holes, linear guide grooves, and sliders, the three-dimensional adjustment function is integrated into a simple mechanical structure, avoiding structural redundancy caused by traditional multi-component stacking and further reducing space occupation.

[0022] 2. Multi-dimensional independent adjustment, convenient, precise, and efficient operation. Three-dimensional adjustment decoupling: Vertical adjustment: Through the cooperation of the first screw and the vertical guide hole, rotating the first nut allows the longitudinal guide component to slide up and down along the vertical guide column without moving the entire support. Longitudinal adjustment: The second screw engages with the longitudinal linear guide groove via slider I; rotating the second nut drives the transverse guide beam to slide back and forth along the longitudinal linear guide groove. Simultaneously, the cooperation of slider II and transverse linear guide groove I assists in fixation, achieving precise longitudinal positioning. Transverse adjustment: The equipment mounting base is directly slidably connected to the transverse linear guide groove II via slider III, allowing for quick left and right position adjustment of the barcode scanner. Auxiliary operation design: The first, second, and third nuts are all equipped with extended auxiliary operating rods, allowing for quick manual adjustment without tools, avoiding the cumbersome operation of traditional knobs or complex mechanisms, significantly shortening adjustment time and improving efficiency. Precise guiding and positioning: The cooperation between the linear guide groove and the slider provides rigid guidance. Compared to the traditional adjustment method of "moving the entire support," it avoids positional deviation, achieving precise positioning and adapting to the rapid alignment of single positions of pallet boxes of different sizes.

[0023] 3. Controllable costs, suitable for large-scale promotion. Low material and processing costs: By abandoning all-aluminum profiles and multiple complex mechanical components, it mainly uses standard parts and simple machined parts such as screws, nuts, guide grooves, and sliders, significantly reducing material costs; the simplified structure makes the production and assembly process more efficient, reducing processing time and process complexity. Low maintenance costs: The modular design facilitates disassembly and replacement of parts, and the adjustment mechanism is less prone to failure due to complex structure, making later maintenance significantly less difficult and costly than existing technologies.

[0024] 4. Highly targeted functionality, adaptable to automated production line scenarios. Dynamic adjustment advantage: For high-frequency scenarios with changes in the position and size of pallet boxes and packing slips, it provides independent and rapid vertical, longitudinal, and lateral adjustments without the need for machine downtime or overall relocation. This ensures that the barcode scanner is compatible with the packing slip position, improves the continuity and stability of automated production lines, and avoids production stoppages caused by barcode scanning failures.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0031] Therefore, the following detailed description of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] This embodiment discloses a three-dimensional adjustment device for scanner installation on an automated production line, as a preferred implementation of this technical solution, such as... Figure 1 As shown, a three-dimensional adjustment architecture is constructed based on the Cartesian coordinate system, including a vertical guide column 1, a longitudinal guide component, a transverse guide beam 8, and an equipment mounting base 11.

[0034] The longitudinal guide assembly, through the cooperation of the first fastener 3 and the first guide structure, is vertically slidably connected to the vertical guide column 1 to achieve vertical (Z-axis) adjustment of the device. Specifically: the first guide structure (such as a T-shaped guide rail / dovetail groove) on the vertical guide column 1 can cooperate with the sliding pair of the longitudinal guide assembly to form a vertical motion pair; the first fastener 3 (such as a bolt group with a flange face) generates frictional torque to lock the longitudinal guide assembly during tightening by compressing spring washers or elastic washers, thereby fixing the Z-axis position of the device.

[0035] The transverse guide beam 8, through the cooperation of the second fastener 7 and the second guide structure, is adjustable in the longitudinal direction and slides with the longitudinal guide assembly, enabling longitudinal (Y-axis) adjustment of the device. Specifically: the second guide structure of the longitudinal guide assembly (such as a linear guide rail / rectangular slide rail) and the transverse guide beam 8 form a horizontal forward and backward motion pair; the second fastener 7 (such as an internal hexagon set screw) releases the longitudinal freedom of the transverse guide beam 8 when loosened by tightening the anti-slip teeth or damping layer on the side of the guide rail, and fixes the Y-axis coordinate of the device through mechanical engagement after tightening.

[0036] The device mounting base 11 is laterally slidably connected to the transverse guide beam 8 via a third guide structure, used to mount the scanner device 13 and achieve lateral (X-axis) adjustment of the device. Specifically, the third guide structure adopts a non-powered self-positioning slide rail (such as a linear guide rail with a ball bearing retainer), and the device mounting base 11 achieves unobstructed sliding through the built-in ball bearing assembly. Further optimization design involves setting a magnetic positioning block or elastic buckle at the end of the slide rail to ensure that the mounting base automatically positions itself after reaching the target position without the need for additional fastening.

[0037] Example 2

[0038] This embodiment discloses a three-dimensional adjustment device for scanner installation on an automated production line. As a preferred embodiment of this technical solution, it differs from Embodiment 1 in that the longitudinal guide component includes a longitudinal guide beam 4 and a right-angle tripod 6. The longitudinal guide beam 4 and the right-angle tripod 6 form a triangular support structure, which can maximize torsional stiffness. The right-angle tripod 6 can be made of high-strength aluminum alloy die-casting, with its two right-angled sides forming a column mating surface (first right-angled side) and a guide beam connecting surface (second right-angled side). The column mating surface is fitted to the vertical guide column 1. Furthermore, a sliding groove matching the first guide structure (such as a T-shaped guide rail) can be machined on the surface of the right-angle tripod 6 to achieve a vertical sliding connection with the vertical guide column 1. The guide beam connecting surface is rigidly connected to the longitudinal guide beam 4 by welding or high-strength bolts, allowing the second guide structure to be mounted on the longitudinal guide beam 4.

[0039] Example 3

[0040] This embodiment discloses a three-dimensional adjustment device for scanner installation on an automated production line. As a preferred embodiment of this technical solution, it differs from embodiments 1 and 2 in that it employs a through-type connection design using a vertical guide hole 2 combined with fasteners, further simplifying and compacting the structure. Specifically: the first guide structure is a vertical guide hole 2; the vertical guide hole 2 is radially through the vertical guide column 1 and extends axially along the vertical guide column 1. Based on this, the first fastener 3, after radially passing through the vertical guide hole 2 along the vertical guide column 1, connects to the longitudinal guide assembly. Thus, the first fastener 3 and the vertical guide hole 2 cooperate to form a vertical kinematic pair, eliminating the need for additional sliding pairs in the longitudinal guide assembly, further simplifying the device structure.

[0041] Example 4

[0042] This embodiment discloses a three-dimensional adjustment device for scanner installation on an automated production line. As a preferred implementation of this technical solution, the difference from embodiment 3 is that the first fastener 3 includes a first screw 3.1 and a first nut 3.2.

[0043] The first screw 3.1 can be made of high-strength alloy steel. One end of the first screw 3.1 is fixedly connected to the longitudinal guide assembly; the other end of the first screw 3.1 is radially penetrated through the vertical guide post 1 via the vertical guide hole 2 and is threadedly adjustablely connected to the first nut 3.2. Furthermore, the first nut 3.2 is provided with an extension auxiliary operating rod 12.

[0044] Based on this, during the vertical (Z-axis) adjustment of the device, the first nut 3.2 is driven to move axially along the first screw 3.1 by rotating the extended auxiliary operating rod 12, and the rotational motion is converted into radial pressure by utilizing the helix angle of the thread. In the loosened state: the first nut 3.2 is screwed to the end of the first screw 3.1, and the first screw 3.1 is in clearance fit with the vertical guide hole 2, allowing the longitudinal guide assembly to slide freely vertically. In the locked state: the first nut 3.2 is tightened until it contacts the surface of the vertical guide column 1, thereby applying a preload to lock the Z-axis position of the device.

[0045] Example 5

[0046] This embodiment discloses a three-dimensional adjustment device for scanner installation on an automated production line. As a preferred embodiment of this technical solution, the difference from embodiments 1-4 is that the second guide structure includes a longitudinal linear guide groove 5, and the second fastener 7 includes a second screw 7.1 and a second nut 7.2, with the second nut 7.2 threadedly adjustable to the second screw 7.1. The longitudinal linear guide groove 5 is formed on the bearing surface of the longitudinal guide assembly, using a T-shaped or dovetail cross-section, and can be formed in one step by a CNC milling machine. One end of the second screw 7.1 is fixed with a slider I 7.3, which slides and engages with the longitudinal linear guide groove 5; the other end of the second screw 7.1 is connected to the transverse guide beam 8.

[0047] Based on this, during the longitudinal (Y-axis) adjustment of the device, the second nut 7.2 is driven to move axially along the second screw 7.1, and the helix angle of the thread converts the rotational motion into radial pressure. In the loosened state: the second nut 7.2 is screwed to a position close to the middle of the second screw 7.1, and the second screw 7.1 and slider I 7.3 are in clearance fit with the longitudinal linear guide groove 5, allowing the transverse guide beam 8 to slide freely longitudinally together with the second guide structure. In the locked state: the second nut 7.2 is tightened to contact the surface of the longitudinal guide assembly, thereby applying a preload to lock the Y-axis position of the device.

[0048] Example 6

[0049] This embodiment discloses a three-dimensional adjustment device for scanner installation on an automated production line. As a preferred embodiment of this technical solution, the difference from Embodiment 5 is that the second guide structure further includes a transverse linear guide groove I9, and the second fastener 7 further includes a third nut 7.4, which is threadedly and adjustablely connected to the second screw 7.1. The transverse linear guide groove I9 ​​is ​​formed on the transverse guide beam 8 (along the X-axis direction) and can adopt the same T-shaped or dovetail-shaped cross-section as the longitudinal guide groove. A slider II 7.5 is fixed to one end of the second screw 7.1 connected to the transverse guide beam 8, and is slidably engaged with the transverse linear guide groove I9 ​​via the slider II 7.5.

[0050] Based on this, this embodiment, while enabling position adjustment of the device in the X-axis direction through the third guide structure, allows for further position adjustment in the X-axis direction when a larger adjustment is required. This can be achieved by adjusting the position of the transverse guide beam 8 through the cooperation of the second fastener 7 and the transverse linear guide groove I9. In other words, this technical solution expands the position adjustment range in the X-axis direction without increasing the overall size of the device.

[0051] In addition, without considering the adjustment range of the X-axis position, the position of the transverse guide beam 8 can be adjusted by the cooperation of the second fastener 7 and the transverse linear guide groove I9, thereby adjusting the center of gravity of the device.

[0052] Correspondingly, when positioning the transverse guide beam 8, the third nut 7.4 is driven to move axially along the second screw 7.1, and the helix angle of the thread converts the rotational motion into radial pressure. In the loosened state: the third nut 7.4 is screwed to a position close to the middle of the second screw 7.1, and the second screw 7.1 and slider II 7.5 are clearance-fitted with the transverse linear guide groove I 9, allowing the transverse guide beam 8 to slide freely longitudinally along the X-axis. In the locked state: the third nut 7.4 is tightened to the surface of the transverse guide beam 8, thereby applying a preload to lock the X-axis position of the device.

[0053] Example 7

[0054] This embodiment discloses a three-dimensional adjustment device for scanner installation on an automated production line. As a preferred embodiment of this technical solution, the difference from embodiment 6 is that the second nut 7.2 and the third nut 7.4 are respectively provided with extended auxiliary operating rods 12. When it is necessary to rotate the second nut 7.2 and the third nut, force can be applied by the corresponding extended auxiliary operating rods 12 without the need for other auxiliary tools, making the operation convenient and quick.

[0055] Example 8

[0056] This embodiment discloses a three-dimensional adjustment device for scanner installation on an automated production line. As a preferred embodiment of this technical solution, based on any of the embodiments 1-7, the third guide structure includes a transverse linear guide groove II 10 and a slider III. The transverse linear guide groove II 10 is opened along the length direction (X-axis) of the transverse guide beam 8 and can adopt an industry standard T-slot. The slider III is a standard part for sliding engagement with the transverse linear guide groove II 10 and is fixed on the equipment mounting base 11, so that the equipment mounting base 11 can slide along the length direction (X-axis) of the transverse guide beam 8.
