A labeling machine for finished distribution boxes

Abstract

This invention relates to the field of marking and punching technology, and discloses a marking machine for finished distribution boxes, including a frame. This invention drives a pressing roller to rotate and move upwards, pressing the punched area of ​​the distribution box label. This effectively smooths out the downward deformation of the punched opening caused by punching, keeping the label surface flat and preventing gaps between the label and the distribution box assembly surface during subsequent assembly. This ensures the overall neatness of the distribution box's appearance and prevents dust, moisture, and other impurities from entering the assembly area, improving stability and service life. Simultaneously, through the guide plate's downward and outward movement grooves in conjunction with the drive assembly, the support seat can be vertically separated from the label and then moved horizontally outwards, moving the support seat and internal waste material to the operating area. Furthermore, the synchronous plate drives the top block upwards, automatically ejecting the punched waste material from the support seat. Waste cleaning can be completed without disassembling the workpiece, avoiding processing interruptions, significantly reducing additional operating steps, and effectively improving overall processing efficiency.

Description

Technical Field

[0001] This invention belongs to the field of marking and punching technology, specifically, it relates to a marking machine for labels on finished electrical distribution boxes. Background Technology

[0002] As a core device in the power system used to distribute electrical energy and protect circuit safety, the finished nameplate of the distribution box is a key component for identifying equipment specifications, models, production information, and safety parameters. The processing accuracy and assembly fit of the nameplate directly affect the overall standardization and safety of the distribution box. Currently, in the processing of finished distribution box nameplates, the two core processes of marking (engraving relevant equipment information) and punching (for nameplate assembly and fixing) are both completed on the same integrated processing equipment. This equipment integrates laser marking and punching functions, eliminating the need to transfer nameplates between multiple machines and simplifying the processing flow.

[0003] In the aforementioned integrated marking and punching equipment, the instantaneous impact force of the punching head on the nameplate during the punching process is concentrated at the punching position. This causes the punched opening of the nameplate to easily deform downwards, forming a localized uneven area. During subsequent assembly, such uneven nameplates cannot fit tightly against the mounting surface of the distribution box, resulting in noticeable gaps. This not only affects the appearance's neatness but also allows dust, moisture, and other impurities to enter the assembly area, potentially leading to loosening and corrosion over time, affecting the nameplate's stability and lifespan. Furthermore, to facilitate the collection of punching waste, the waste generated during punching falls directly to the bottom of the workpiece. Since the waste is located in a closed space below the workpiece, operators cannot remove it without disassembling the workpiece or interrupting the integrated equipment's processing flow. The waste can only be cleaned from the groove after the entire batch of processing is completed. This method not only adds extra steps and significantly reduces overall processing efficiency but may also affect the accuracy of subsequent punching operations due to excessive waste accumulation in the groove.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0021] Example 1:

[0022] like Figures 1 to 9 As shown, a labeling machine for finished distribution boxes includes a frame 1.

[0023] A support plate 11 is installed on the frame 1, and the support plate 11 is used to support the distribution box nameplate. A laser marking machine 4 is installed on the frame 1, and the laser marking machine 4 is used to mark the distribution box nameplate. A punching assembly for punching holes in the distribution box nameplate is installed on the frame 1. A support seat 17 is provided on the support plate 11, and the support seat 17 corresponds to the output end of the punching assembly. A guide plate 25 is installed at the bottom of the support plate 11. The guide plate 25 has a lower sliding groove 26 and an outer sliding groove 27. The lower sliding groove 26 is used to guide the support seat 17 to slide vertically and separate it from the distribution box sign, while the outer sliding groove 27 is used to guide the support seat 17 containing punching waste to separate horizontally. A drive motor 29 is installed on the side wall of the bearing seat 17, and a plug shaft 30 is installed at the output end of the drive motor 29. A threaded block 31 is inserted into the plug shaft 30, and the threaded block 31 is engaged with the threaded sleeve 41 in a fixed state. A pressing roller 34 is installed on the top of the threaded block 31. When the drive motor 29 starts, the pressing roller 34 rotates and moves upward to squeeze the punched position of the power distribution box sign to ensure its flatness. It also drives the top block 38 inside the bearing seat 17 to move upward, so that the punching waste is separated. A drive assembly for moving the support base 17 is also installed at the bottom of the support plate 11.

[0024] like Figures 1 to 9 As shown in the specific embodiment, four support legs 2 are installed at the bottom of the frame 1, and anti-slip pads are installed at the bottom of the four support legs 2. Reinforcing ribs 3 are installed between adjacent support legs 2, and the heights of adjacent reinforcing ribs 3 are different. A controller 8 is installed on the frame 1. The controller 8 is used to control the start and stop of the laser marking machine 4, the punching assembly, the drive motor, and the drive assembly. The four support legs 2 and the bottom anti-slip pads can improve the placement stability of the frame 1 and prevent shaking during equipment operation. The reinforcing ribs 3 with different adjacent heights can enhance the structural strength of the frame 1 and prevent the frame 1 from deforming under long-term stress. The controller 8 realizes centralized control of all components.

[0025] like Figures 1 to 9 As shown, the punching assembly further includes a punching hydraulic push rod 5, with a bracket 6 mounted on the output end of the punching hydraulic push rod 5. The bracket 6 is arched, and punching heads 7 are mounted on both ends of the bracket 6. The bottom of the punching head 7 is opposite to the support seat 17. A groove 18 is provided on the support plate 11, and the support seat 17 is placed inside the groove 18. The punching hydraulic push rod 5 provides sufficient punching power, and the arched bracket 6 ensures that the punching heads 7 at both ends are subjected to uniform force, realizing synchronous double-hole punching of the nameplate and improving processing efficiency. The support seat 17 is placed inside the groove 18, which ensures that the support seat 17 is installed stably and facilitates the collection of punching waste, preventing waste from scattering.

[0026] like Figures 1 to 9As shown, a base plate 10 is further mounted on the top of the frame 1, a base 9 is mounted on the top of the base plate 10, and four connecting posts 13 are mounted on the base 9. The tops of the connecting posts 13 are connected to the bottom of the support plate 11. The cooperation of the base plate 10, the base 9, and the four connecting posts 13 provides stable support for the support plate 11, ensuring that the support plate 11 is firmly installed and preventing deformation or shaking of the support plate 11 during the nameplate processing, thus ensuring processing accuracy.

[0027] like Figures 1 to 9 As shown, the outer wall of the support plate 11 has a notch 12, which facilitates the operator's handling of the distribution box label. Positioning blocks 14 are installed at the four corners of the support plate 11, with positioning shafts 16 rotatably mounted on the positioning blocks 14. A clamping plate 15 is mounted on the positioning shaft 16. When the clamping plate 15 rotates to the distribution box label, it positions the label by cooperating with the support plate 11. The notch 12 improves the convenience of label handling and placement, reduces the difficulty of manual operation, and the cooperation of the positioning blocks 14, positioning shafts 16, and clamping plates 15 enables rapid and accurate label positioning, preventing label displacement during marking and punching processes and improving processing accuracy.

[0028] Example 2:

[0029] The difference between the above embodiments and this embodiment is that: Figures 1 to 9 As shown, the drive assembly includes an electric push rod 19, a synchronous frame 20 is installed at the output end of the electric push rod 19, positioning rods 21 are installed at both ends of the synchronous frame 20, a positioning plate 22 is installed at the end of the positioning rod 21, and the diameter of the positioning plate 22 is larger than the diameter of the positioning rod 21, a positioning seat 23 is installed on the outer wall of the positioning rod 21, a slide rod 24 is installed on the back of the positioning seat 23, the end of the slide rod 24 is connected to the side wall of the bearing seat 17, and the slide rod 24 is slidably disposed in the lower moving groove 26, the end of the lower moving groove 26 is connected to the end of the outer moving groove 27, the lower moving groove 26 is in a vertical state, and the outer moving groove 27 is in an inclined state. The electric push rod 19 drives the positioning rods 21 and slide rods 24 at both ends to move synchronously through the synchronous frame 20, ensuring that the bearing seat 17 is subjected to uniform force. The positioning plate 22 can prevent the positioning rods 21 from falling off. The positioning seat 23 improves the installation stability of the slide rods 24. The cooperation between the slide rods 24 and the lower moving groove 26 and the outer moving groove 27 realizes the smooth switching between the vertical downward movement and the horizontal outward movement of the bearing seat 17, improving the continuity of the action.

[0030] like Figures 1 to 9As shown, in a specific embodiment, a connecting frame 28 is installed on the side wall of the support base 17. The end of the connecting frame 28 is connected to the housing of the drive motor 29. The support base 17 is connected to the threaded sleeve 41. A connecting sleeve 32 is installed on the threaded sleeve 41. A pair of support frames 33 are installed on the top of the connecting sleeve 32. A pressing roller 34 is rotatably installed on the top of the pair of support frames 33. The pressing roller 34 is located on the outer side wall of the threaded sleeve 41. The connecting frame 28 realizes a stable connection between the drive motor 29 and the support base 17, ensuring that the drive motor 29 moves synchronously with the support base 17. The connecting sleeve 32 and the support frames 33 provide stable installation support for the pressing roller 34, ensuring that the pressing roller 34 can rotate and move upward stably, achieving precise leveling of the punching position of the sign.

[0031] like Figures 1 to 9 As shown, further, a groove 35 is provided on the outer wall of the connecting sleeve 32, and a sliding sleeve 36 is rotatably installed on the groove 35. A synchronous plate 37 is installed on the sliding sleeve 36. The synchronous plate 37 is movably connected to the threaded sleeve 41 and the side wall of the bearing seat 17 respectively. A top block 38 is installed at the end of the synchronous plate 37, and the top block 38 is in the shape of a boss. The top block 38 is inserted into the inner cavity of the bearing seat 17. A limit rod 39 is vertically installed through the synchronous plate 37. The limit rod 39 is in a vertical state. The bottom of the limit rod 39 is connected to the side wall of the connecting frame 28. A limit plate 40 is installed on the top of the limit rod 39. The diameter of the limit plate 40 is larger than the diameter of the limit rod 39. The cooperation between the slide groove 35 and the slide sleeve 36 ensures that the synchronous plate 37 can move synchronously with the threaded block 31. The boss-shaped top block 38 can realize the rapid ejection of waste materials. The limit rod 39 and the limit plate 40 can limit the movement range of the synchronous plate 37, avoid excessive movement of the synchronous plate 37 and damage to the components, and improve the stability of equipment operation.

[0032] The implementation principle of the label marking machine for finished distribution boxes of the present invention is as follows: In use, the operator first places the distribution box nameplate to be marked and punched on the support seat 17 of the support plate 11. Using the positioning blocks 14, positioning shafts 16 and clamping plates 15 at the four corners of the support plate 11, the clamping plate 15 is rotated to the top of the distribution box nameplate. The clamping plate 15 and the support plate 11 cooperate to achieve precise positioning of the distribution box nameplate, avoiding displacement during subsequent marking and punching. At the same time, the notch 12 opened on the outer wall of the support plate 11 allows the operator to quickly pick up and place the distribution box nameplate, improving the ease of operation.

[0033] After positioning is completed, the equipment is started by the controller 8 installed on the frame 1. The controller 8 synchronously controls the laser marking machine 4, the punching assembly, the drive motor 29, and the drive assembly to operate according to the preset program. Among them, after the laser marking machine 4 is started, it accurately marks the power distribution box label positioned on the carrier 17, completing the engraving of the required information on the label.

[0034] At the same time, the punching assembly is started simultaneously. The punching hydraulic push rod 5 drives the arched bracket 6 and the punching heads 7 at both ends to move down and complete the punching operation by aligning with the preset punching position of the power distribution box sign. The waste generated by punching falls directly into the lower support seat 17 and is collected, completing the initial collection and storage of waste.

[0035] After the punching process is completed, the controller immediately starts the drive assembly. The electric push rod 19 drives the synchronous frame 20, positioning rod 21 and sliding rod 24 to move synchronously. First, the sliding rod 24 is driven to slide vertically along the vertical downward groove 26 on the guide plate 25, which drives the entire bearing seat 17 to move vertically downward, so that the bearing seat 17 is completely separated from the above power distribution box sign, avoiding scratch damage to the sign. After moving to the lower position, the sliding rod 24 slides into the inclined outer groove 27. With the guidance of the outer groove 27, the bearing seat 17 and the internal punching waste are moved to the outside, so that the bearing seat 17 moves to the outside working area of ​​the equipment. At the same time, the connecting frame 28 and the drive motor 29 fixed on it are moved to the position directly below the punching position of the sign, completing the work station switch.

[0036] After the workstation is adjusted, the controller starts the drive motor 29. The drive motor 29 drives the insert shaft 30 to drive the threaded block 31 to rotate. Relying on the meshing transmission structure between the threaded block 31 and the fixed threaded sleeve 41, the threaded block 31 rotates and rises at the same time, which simultaneously drives the pressing roller 34 at the top of the support frame 33 to rotate and move upward. This allows the pressing roller 34 to fit tightly against the area around the punched hole of the distribution box sign to perform rolling and smoothing operations, effectively smoothing out the warping, dents and other deformations caused after punching, and ensuring the overall flatness of the signboard surface.

[0037] While the pressing roller 34 is moving upward, the sliding sleeve drives the synchronous plate 37 to move vertically and stably upward along the limit rod 39. The synchronous plate 37 pushes the top block 38, which has a boss-shaped end, upward from the inner cavity of the bearing seat 17, pushing the punching waste material remaining inside the bearing seat 17 upward as a whole, realizing automatic removal and cleaning of punching waste material. The entire process of marking, punching, leveling, and waste removal is completed in a continuous manner and is fully automated, which greatly improves the processing efficiency and quality of the distribution box nameplate.

[0038] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
