Description

Technical Field

[0001] This utility model belongs to the field of skin roller manufacturing technology, and in particular relates to a batch-scale automated assembly line for skin rollers. Background Technology

[0002] The core structure of a skin roller typically consists of a plastic top plate, a bottom plate, multiple middle plates, and a metal steel plate, all nested together. Hollow core rods are placed on the top and bottom plates. The middle plates and steel plates are nested on the core rods of the bottom plate. Finally, the core rod of the top plate is inserted into the core rod of the bottom plate to complete the assembly.

[0003] Currently, the assembly and production of skin rollers mostly rely on manual labor or semi-automated equipment. Traditional manual assembly methods have significant drawbacks: First, due to the large number and small size of roller components (especially the middle piece and steel piece), manual picking, alignment and assembly are extremely inefficient and labor-intensive, severely restricting production capacity. Second, human hands directly contact precision parts, which can easily lead to poor product assembly, scratches or contamination due to unstable operation, uneven force or cleanliness issues. Product consistency and yield are difficult to guarantee, posing medical safety risks.

[0004] While some existing semi-automated equipment reduces human intervention to some extent, it still faces many technical bottlenecks. For example, the feeding, positioning, transfer, and pressing processes for different materials are often discrete, and the connection between processes relies on multiple positioning and transfers. This not only results in complex mechanisms and large floor space but also high cumulative errors, affecting assembly accuracy. In particular, for processes such as medium-sized pieces and steel sheets that require the sequential assembly of multiple identical parts, semi-automated equipment typically uses a single-piece feeding method, which is repetitive and has a long cycle time, resulting in limited improvement in production efficiency. Furthermore, traditional linear or substation layouts make it difficult to achieve the circulation of materials and the reuse of tooling bases, leading to low equipment utilization and insufficient overall automation and intelligence.

[0005] Therefore, there is an urgent need in this field for a fully automated skin roller assembly line that is highly integrated, fast-paced, precise, and capable of fully unmanned operation, in order to fundamentally solve the problems of low production efficiency, poor product consistency, and potential hygiene risks in existing technologies. Summary of the Invention

[0006] The purpose of this invention is to provide a batch-scale automated assembly line for skin roller needles.

[0016] A method for using a batch-automated assembly line for skin rollers includes the following steps: The SS01 bottom film feeding device, middle film feeding device, and top film feeding device store bottom films, middle films, and top films respectively in their hoppers, and are arranged sequentially in the material grooves of the corresponding guide clamps. The middle films in the front row of the middle film feeding device are temporarily stored in the first preparation plate, the top films in the front row of the top film feeding device are temporarily stored in the second preparation plate, and the bottom films in the front row of the bottom film feeding device are locked by the ten locking rods of the locking mechanism.

[0017] This utility model has the following beneficial effects: 1. This utility model, through the design of a novel conveying system, organically combines the chute and the conveyor belt to form a U-shaped circular layout. A longitudinal pushing mechanism is used for the transfer of tooling seats between the chute and the conveyor belt, and a transverse pushing mechanism is used to achieve step-by-step precise feeding of tooling seats in the first and second chutes, forming a closed and continuous material flow. The tooling seats circulate in the channel, realizing seamless connection of processes such as feeding, assembly, and pressing, minimizing idle waiting time, and making the production cycle compact and efficient.

[0018] 2. This utility model, by considering the different characteristics and quantity requirements of the top sheet, bottom sheet, middle sheet, and steel sheet, designs specialized bottom sheet feeding devices, middle sheet feeding devices, steel sheet feeding devices, and top sheet feeding devices. Each feeding module can automatically complete the arrangement, positioning, and supply of materials, ensuring that ten materials are precisely positioned for the robotic arm each time. The material transfer operation is performed by an adsorption-type robotic arm, with gentle movements and precise positioning, effectively avoiding damage, displacement, or contamination of small precision parts during the transfer process. The entire assembly process is completed under the control of a preset program, eliminating human interference and ensuring the uniformity of assembly force and position for each product, thus significantly improving the product yield.

[0019] 3. This utility model, by designing ten ends on the tooling base and cooperating with a bottom sheet feeding device, middle sheet feeding device, steel sheet feeding device and top sheet feeding device that output ten pieces of material at a time, allows one tooling base to realize the automated assembly of ten products at a time. It adopts a parallel operation mode, and compared with the traditional single-piece serial production, the output per unit time increases by an order of magnitude, which greatly improves the overall production capacity.

[0020] 4. This utility model sets up a double-row adsorption mechanism between the medium sheet feeding device and the steel sheet feeding device. The medium sheet and steel sheet are fed alternately through the double-row adsorption mechanism. The number of medium sheet feeding devices and steel sheet feeding devices is designed to be three. According to the number of medium sheets and steel sheets, they can be installed in three batches, which improves the production cycle, reduces the time occupied, and improves work efficiency.

[0021] 5. This utility model can complete all assembly processes in one stop. Starting from the bottom sheet feeding, it automatically completes the multiple insertions of the middle sheet and steel sheet in sequence, until the final pressing of the top sheet. All core processes are automatically completed on an integrated production line, truly realizing "one-click" production from parts to finished products. It reduces material turnover and secondary positioning in intermediate links. Moreover, the U-shaped channel not only ensures the continuity of logistics, but also allows the tooling of the pressed product to automatically flow to the unloading station. The empty tooling returns to the starting feeding station through the circulation channel, realizing the automatic recycling and reuse of tooling, reducing auxiliary time and management costs, and achieving a high level of automation and intelligence.

[0035] The first conveyor line 5 and the second conveyor line 6 have the same structural features. The first conveyor line 5 includes an active roller, a driven roller and a motor reducer installed on the main frame 1. Two narrow belts are provided on the active roller and the driven roller. Openings are provided at corresponding positions at both ends of the narrow belts on the main frame 1 for the narrow belts to pass through, so that the upper part of the narrow belt slides along the upper surface of the main frame 1.

[0036] Among them, such as Figure 1-4 As shown, the first slide 3 and the second slide 4 are both composed of two metal edges. The metal edges are composed of several linearly distributed metal strips that are parallel to the length direction of the main frame 1. The spacing between the two metal edges is set to be consistent with the width of the tooling base 7. Among them, such as Figure 1-4 As shown, both sides of the first conveyor line 5 and the second conveyor line 6 are provided with limiting edges parallel to the width direction of the main frame 1. The material and cross-section of the limiting edges are the same as the material and cross-section of the metal strip.

[0037] Among them, such as Figure 2-3 As shown, a block is embedded in the top surface of the main frame 1, which serves as the bottom surface of the first slide groove 3 and the second slide groove 4, as well as the position supporting the narrow strip. The outer surfaces of the block, the limiting edge, and the sub-metal strips that make up the metal strip are all coated with a low-friction coating.

[0038] An opening is provided in the first slide 3 at a position opposite to the bottom sheet feeding device 11 and the top sheet feeding device 14. The opening is located on the outer metal edge of the first slide 3. A horizontal pusher cylinder is provided at the position corresponding to the opening. A pusher plate is provided at the end of the horizontal pusher cylinder. The tooling seat is fastened by applying a pushing force through the pusher plate. Since the bottom sheet and the end 701 and the top sheet and the bottom sheet need to be concentrically positioned, this device is provided to ensure the high stability of the tooling seat 7 and provide a guarantee.

[0039] Among them, such as Figure 6 and Figure 8 As shown, the top of the hopper 15 is fitted with a hinged door panel for feeding. Except for the two side panels which are made of stainless steel, the other panels of the hopper 15 are transparent and observable plastic panels. The hopper 15 includes a rectangular part 1501 at the bottom, and a trapezoidal part 1502 integrally formed on the top of the rectangular part 1501. A conveyor belt 1503 is provided on the rear side of the rectangular part 1501 to support the material in the trapezoidal part 1502 and to feed the material in batches. A stirring shaft mechanism 1054 is provided on the front side of the rectangular part 1501. Flexible stirring blades are fixed on the periphery of the stirring shaft mechanism 1054. The length of the stirring blades is the same as the width of the inner cavity of the rectangular part 1501. The vibration of the electromagnetic vibration table 16 ensures that the material flows into the trough of the guide clamp.

[0040] Among them, the top of the main frame 1 is fixed with several control cabinets. The front side of the control cabinet is equipped with a panel that integrates various buttons and touch bottles for the automatic control and status display of various devices.

[0041] A method for using a batch-automated assembly line for skin rollers includes the following steps: The bottom sheet 27, middle sheet 28 and top sheet 29 are stored in the hopper 15 of the bottom sheet feeding device 11, the middle sheet feeding device 12 and the top sheet feeding device 14 respectively, and are arranged in the material groove of the corresponding guide clamp plate. The middle sheet 28 in the front row of the middle sheet feeding device 12 is temporarily stored in the first preparation plate 18, and the top sheet 29 in the front row of the top sheet feeding device 14 is temporarily stored in the second preparation plate 25. The bottom sheet 27 in the front row of the bottom sheet feeding device 11 is locked by the ten locking rods 1704 of the locking mechanism 17. All steel sheet through rods 1302 on the rotary table 1301 are stacked with steel sheets 30. SS02 Tooling seat 7 circulation: The first chute 3 and the second chute 4 are filled with tooling seats 7 with their ends touching. Some tooling seats 7 are temporarily stored on the first conveyor line 5 and the second conveyor line 6. There is a tooling seat 7 arranged in front of each other at the corresponding positions of the bottom film feeding device 11, the three middle film feeding devices 12, the top film feeding device 14, the pressing station 22, the image detection device 26 and the finished product conveyor line 2. The transverse pushing mechanism 8 pushes the tooling seat 7 at the front end of the first slide 3 and the second slide 4 into the first slide 3 and the second slide 4. The pushing stroke is consistent with the length of the tooling seat 7. After the pushing is completed, it is reset. The second conveyor line 6 and the first conveyor line 5 push the next tooling seat 7 to the front end of the first slide 3 and the second slide 4 for preparation. The clearance cylinder 903 of the longitudinal pushing mechanism 9 lifts the two sets of clamping rollers 905. As the transverse pushing mechanism 8 pushes, the tooling seat 7 at the tail end of the first slide 3 and the second slide 4 is inserted between the two sets of clamping rollers 905. The clamping rollers 905 and the tooling seat 7 are driven to move towards the first conveyor line 5 and the second conveyor line 6 through the secondary slide table 901. After moving into place, the clamping rollers 905 are controlled to retract downwards and reset. All tooling seats 7 are circulated in the U-shaped conveyor line, and the stroke of tooling seats 7 driven in the first chute 3 and the second chute 4 is consistent with the length of tooling seat 7 each time. SS03 Film 27 Loading: The rotating shaft 1902 flips the receiving plate 1903 to the front end of the guide clamp plate of the film loading device 11, controls the locking cylinder 1702 to retract and drive the locking rod 1704 to lift, so that the locking rod 1704 disengages from the film 27 in the material groove. The front row of film 27 slides onto the receiving plate 1903, and the film 27 arranged in the material groove of the guide clamp plate moves forward by the distance of one film 27. The locking cylinder 1702 extends and drives the locking rod 1704 to insert into the core cylinder of the film 27 axis. The system is in a limited position. The horizontal cylinder 1904 extends to control the pad 1905 to extend forward. The rotating shaft 1902 controls the receiving plate 1903 and the bottom piece 27 above it to rotate 180°. The pad 1905 and the receiving plate 1903 clamp the ten bottom pieces 27. At this time, the ten bottom pieces 27 are located directly above the ten ends 701 on the tooling base 7. The horizontal cylinder 1904 is controlled to reset, the pad 1905 is pulled out, and the core tubes of the ten bottom pieces 27 are sleeved on the ten ends 701 with the core tubes facing upward. SS04 Medium-sized sheet 28 and steel sheet 30 are loaded: The inner ten second adsorption units 2103 of the double-row adsorption mechanism 21 are directly above the ten bottom plates 27 on the tooling base 7, and the outer ten second adsorption units 2103 adsorb the steel plates 30 on the ten steel plate through rods 1302. The sliding box 2101 drives the two rows of second adsorption units 2103 to move inward, releasing the adsorption of the ten outer steel plates 30. The steel plates 30 are fitted onto the core cylinder of the ten bottom plates 27 by gravity. The inner ten second adsorption units 2103 move to directly above the first material preparation plate 18 of the middle plate feeding device 12 and adsorb the middle plate 28. The slide box 2101 is reset, and the ten outer second adsorption units 2103 adsorb the steel sheets 30 on the ten steel sheet rods 1302. The ten inner second adsorption units 2103 put the middle sheet 28 onto the core cylinder of the bottom sheet 27. The middle sheet 28 and steel sheet 30 are sequentially set according to the above method. The three middle sheet feeding devices 12 and the three steel sheet feeding devices 13 are divided into three batches. A total of eight middle sheets 28 and nine steel sheets 30 are set on each bottom sheet 27. SS05 Image Detection Device 26 acquires the assembled film 27, intermediate film 28 and steel sheet 30 on the tooling stand 7; SS06 Top sheet 29 feeding: The top sheet on the second preparation plate 25 of the top sheet feeding device 14 is adsorbed and moved to the semi-finished product on the tooling seat 7 by the second single-row adsorption mechanism 20. The core of the top sheet 29 is facing down and inserted into the core of the bottom sheet 27. SS07 Product Pressing: Pressing station 22 presses the top piece 29 downward through ten pressing points 2204 to achieve an interference fit between the top piece 29 and the bottom piece 27, and the product assembly is completed; SS08 Finished Product Output: The first single-row adsorption mechanism 10 adsorbs and transfers ten finished products from the tooling seat 7 to the finished product conveyor line 2.
