Description

Technical Field

[0001] This utility model relates to the field of edge trimming devices for injection molded parts, specifically an edge trimming device for injection molded parts of a sweeping robot. Background Technology

[0002] In the manufacturing process of robotic vacuum cleaners, the trimming of injection-molded parts is a crucial step. After molding, the edges of injection-molded parts often have excess burrs and flash, which not only affect the appearance quality of the robotic vacuum cleaner but may also adversely impact its assembly and performance. Therefore, efficiently and accurately removing excess material from the edges of injection-molded parts is a key step in ensuring the quality of robotic vacuum cleaner products.

[0003] Traditional methods for trimming injection-molded parts for robotic vacuum cleaners primarily rely on manual operation. Workers use simple tools such as scissors and files to manually trim and grind the edges of the injection-molded parts. On one hand, manual operation is extremely inefficient, as workers need to process each injection-molded part individually, resulting in slow processing speeds that cannot meet the demands of large-scale production. Furthermore, prolonged repetitive labor can easily lead to worker fatigue, affecting the quality and consistency of trimming. On the other hand, the precision of manual operation is difficult to guarantee; differences in operating techniques and pressure among different workers can easily cause uneven trimming, and may even damage the injection-molded part itself, reducing the product yield.

[0004] With the development of automation technology, some companies have begun to use automated equipment for edge trimming of injection-molded parts for robotic vacuum cleaners. Existing edge trimming equipment typically uses a single blade assembly for this operation. The blade assembly's position adjustment is not flexible enough, generally limited to movement within a two-dimensional plane, making it difficult to adapt to the edge trimming needs of injection-molded parts for robotic vacuum cleaners of different sizes and shapes. For injection-molded parts with complex shapes and irregular edges, a single blade assembly often cannot complete the edge trimming task comprehensively and efficiently, requiring multiple adjustments to the position of the injection-molded part or the angle of the blade assembly, making the operation cumbersome and significantly reducing edge trimming efficiency.

[0005] Furthermore, existing trimming equipment presents inconveniences in terms of tool set replacement and maintenance. The tool sets are usually fixed in a complex manner, requiring the use of multiple tools and consuming considerable time and effort when changing tools, thus affecting the normal operation of the equipment and production efficiency.

[0018] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Reference Figure 1 , Figure 2 and Figure 3 As shown, a device for removing edges from injection-molded parts for a sweeping robot includes a processing table 1. A door frame 2 is mounted above the processing table 1, and an electric cylinder 1 is mounted on the side of the processing table 1 to drive the door frame 2 to move back and forth. A movable seat 3 is slidably mounted on the door frame 2, and an electric cylinder 2 is also mounted on the door frame 2 to drive the movable seat 3 to move horizontally. An electric cylinder 30 is vertically mounted on the front end of the movable seat 3, and a drive assembly 4 is mounted on the output end of the electric cylinder 30. A tool holder 5 is fixedly connected below the drive assembly 4, and a multi-headed blade assembly 6 is rotatably mounted in the tool holder 5. An elastic lock 7 is also mounted on the tool holder 5 to lock the multi-headed blade assembly 6. By setting the electric cylinder 1 to drive the door frame 2 to move back and forth, the electric cylinder 2 to drive the movable seat 3 to move horizontally, and the electric cylinder 30 to drive the assembly 4 to move up and down, the multi-headed blade assembly 6 can flexibly adjust its position in three-dimensional space, thereby enabling edge removal operations on injection-molded parts for sweeping robots of different positions and shapes, greatly improving the applicability and flexibility of the device. The electric cylinder 30 ensures that the drive assembly 4 and the tool holder 5 can be flexibly raised and lowered during use. During processing, the drive assembly 4 drives the tool holder 5 and the multi-head cutter group 6 to rotate and cut edges. The tool holder 5 ensures that the multi-head cutter group 6 can be stably installed, and the operating angle of the multi-head cutter group 6 can be adjusted by rotation to facilitate different edge-cutting processes. At the same time, the elastic locking element 7 can lock the multi-head cutter group 6 to ensure the stability of the edge-cutting process.

[0019] Reference Figure 2 As shown, the drive assembly 4 includes a base 41 and a drive motor 42 that drives the tool holder 5 to rotate. The drive motor 42 is vertically mounted in the base 41 and is fixedly connected to the base 41. The drive motor 42 in the drive assembly 4 provides power for the rotation of the tool holder 5, enabling the multi-head tool set 6 to perform rotary cutting and improve the trimming efficiency. Furthermore, selecting a suitable model of drive motor 42 ensures the stability and reliability of the tool holder 5's rotation, guaranteeing the trimming quality.

[0020] Reference Figure 3 As shown, the tool holder 5 includes a top plate 51, a first vertical plate 52, and a second vertical plate 53. The first vertical plate 52 and the second vertical plate 53 are symmetrically mounted on the lower end face of the top plate 51, and the top plate 51, the first vertical plate 52, and the second vertical plate 53 are integrally formed. The tool holder 5 adopts an integrally formed structure of top plate 51, first vertical plate 52, and second vertical plate 53, ensuring the overall strength and stability of the tool holder 5. At the same time, the tool holder 5 can be made of high-strength aluminum alloy material, which reduces the weight of the tool holder 5, can withstand a certain amount of external force, and extends the service life of the tool holder 5.

[0021] Reference Figure 4 and Figure 5 As shown, the multi-head cutter assembly 6 includes a disc base 61 and rotary cutting blades 62. The rotary cutting blades 62 are evenly mounted on the outer surface of the disc base 61, and are detachably and fixedly connected to the disc base 61. This detachable connection allows for easy replacement of different types of rotary cutting blades 62 according to different edge removal requirements. The high-speed steel rotary cutting blades 62 possess excellent wear resistance and cutting performance, enabling efficient removal of edge material from injection molded parts. The disc base 61 includes a turntable portion 611 and a sleeve 612 for mounting the rotary cutting blades 62. The sleeve 612 is evenly mounted on the outer surface of the turntable portion 611 and is integrally formed with the turntable portion 611. The turntable portion 611 has a positioning groove 610 corresponding to the elastic locking element 7. The integral formation of the turntable portion 611 and the sleeve 612 ensures structural stability and facilitates stable mounting of the rotary cutting blades 62 via the sleeve 612. The positioning groove 610, in conjunction with the elastic locking element 7, accurately locks the position of the multi-head blade assembly 6, ensuring the stability and accuracy of the rotary cutting blade 62 during operation. The disc base 61 can be made of stainless steel to improve its corrosion resistance and extend its service life. Side shafts 613, rotatably connected to the blade holder 5, are fixedly mounted on both sides of the turntable 611, and locking bolts 614 for fixing the rotary cutting blade 62 are provided on the side of the sleeve 612. The side shafts 613 allow the multi-head blade assembly 6 to rotate flexibly within the blade holder 5. The bearing steel material of the side shafts 613 reduces friction during rotation, improving flexibility and efficiency. The locking bolts 614 facilitate the fixing and disassembly of the rotary cutting blade 62, making blade replacement and maintenance convenient.

[0022] Reference Figure 3 and Figure 4 As shown, the elastic locking component 7 includes a base frame 71, a top frame 72, a locking rod 73, and a pull rod 74. The base frame 71 is fixedly installed on the lower end face of the second vertical plate 53, the top frame 72 is fixedly installed on the base frame 71, the locking rod 73 is slidably installed on the base frame 71, and a support spring 731 is fixedly installed between the locking rod 73 and the top frame 72. The locking rod 73 is slidably installed on the top frame 72, and one end of the locking rod 73 is fixed to the top frame 72. The structural design of the elastic locking component 7 allows the locking rod 73 to automatically insert into the positioning groove 610 under the action of the support spring 731, thereby locking the multi-head cutter assembly 6. The locking can be easily released by pulling the pull rod 74, facilitating the replacement or adjustment of the multi-head cutter assembly 6. The elastic locking component 7 can be made of carbon steel or alloy steel, ensuring its strength and wear resistance.

[0023] Working Principle: During actual edge trimming, the injection-molded part of the robot vacuum cleaner is placed on the processing table 1. Based on the position of the injection-molded part and the edge trimming requirements, electric cylinder one is activated, driving the gate frame 2 to move back and forth, so that the multi-head blade assembly 6 roughly reaches the front and rear positions of the injection-molded part. Electric cylinder two is activated, driving the movable seat 3 to move horizontally on the gate frame 2, further adjusting the horizontal position of the multi-head blade assembly 6. Electric cylinder three 30 is activated, causing the drive assembly 4 and the tool holder 5 to move up and down, adjusting the multi-head blade assembly 6 to a suitable height. Drive motor 42 is activated, driving the tool holder 5 to rotate, thereby driving the multi-head blade assembly 6 to rotate, performing the edge trimming operation on the injection-molded part.

[0024] If it is necessary to replace the rotary cutting blade 62, first pull the lever 74 of the elastic locking element 7 to pull the locking rod 73 out of the positioning groove 610, thus releasing the lock on the multi-head blade assembly 6. Then loosen the locking bolt 614 on the side of the sleeve 612, replace the appropriate rotary cutting blade 62, and then tighten the locking bolt 614. Finally, loosen the lever 74, and the locking rod 73, under the action of the support spring 731, inserts into the positioning groove 610, relocking the multi-head blade assembly 6.
