Description

Technical Field

[0001] This invention relates to the field of daily chemical product assembly technology, and in particular to a multi-station assembly device for daily chemical sprayers. Background Technology

[0002] As a commonly used packaging accessory in the daily chemical and personal care industry, daily chemical sprayers are mainly assembled from components such as bottle body, pump core, and top cap. The production process requires the sequential completion of multiple steps such as feeding, pump core pressing, capping, and unloading.

[0003] Existing traditional assembly equipment generally lacks adaptive clamping and coaxial automatic compensation functions. It cannot automatically adjust the clamping space according to product specifications, nor can it achieve micro-alignment and fine adjustment of the workpiece at the moment of pump core pressing and cap pressing. The machine head and workpiece are prone to coaxial deviation. Rigid impacts can easily cause problems such as pump core tilting, shell damage, and cap stripping, resulting in a high product defect rate.

[0004] Therefore, this application provides a multi-station assembly device for daily chemical sprayers to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multi-station assembly device for daily chemical sprayers, so as to solve the problem of lack of adaptive adjustment clamping and coaxial automatic compensation.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A multi-station assembly device for daily chemical sprayers includes a main body with a multi-station component. Above the multi-station component are a pump core pressing structure, a capping structure, and two robotic arm structures for loading and unloading. The multi-station component drives multiple workstation slots, each containing an adjustment component and an anti-deviation compensation component. The multi-station component drives each workstation slot to rotate at the bottom of the robotic arm structure, pump core pressing structure, and capping structure, improving assembly efficiency. The adjustment component automatically adjusts the size and shape of the workstation slots to accommodate different types of daily chemical sprayers. The anti-deviation compensation component works in conjunction with the adjustment component to ensure that, during the pressing of the pump core pressing structure and capping structure, the daily chemical sprayer adaptively adjusts its coaxiality to follow the machine head, preventing increased defect rates due to rigid impact.

[0008] Optionally, the multi-station assembly includes a motor, the drive end of which is driven by a collar, and multiple station slots are fixedly connected to the collar.

[0009] Optionally, the work station slot includes a slot body, the upper half of the slot body has a vertical slide groove one, a trigger plate is slidably connected in the slide groove one, the trigger plate is provided with a trigger groove, and the lower half of the slot body has a horizontal slide groove two.

[0010] Optionally, the adjustment assembly includes multiple inclined surfaces 1 fixedly connected to the inner side of the trigger plate, inclined surfaces 2 slidably connected to the bottom of the inclined surfaces 1, a moving rod 1 fixedly connected to the inclined surfaces 2, and an adjustment clamping plate fixedly connected to the moving rod 1.

[0011] Optionally, a main airbag is installed inside the adjusting clamp, and the main airbag is provided with multiple through holes. Multiple auxiliary airbags are provided on the outside of the adjusting clamp, and the auxiliary airbags are connected to the main airbag through the through holes.

[0012] Optionally, a plurality of springs are installed in the slide groove, and the springs are fixedly connected to the bottom of the trigger plate.

[0013] Optionally, the anti-deviation compensation component includes a second spring installed at the bottom of the inner side of the workstation slot, and a compensation plate is fixedly connected to the top of the second spring.

[0014] Optionally, the anti-deviation compensation component further includes a placement plate that slides within the slide groove two. The upper surface of the placement plate is provided with an inclined surface three. A compensation rod is fixedly connected to the bottom of the trigger plate. An inclined surface four is fixedly connected to the bottom of the compensation rod. The inclined surface four and the inclined surface three are slidably connected.

[0015] Optionally, a second movable rod is fixedly connected to the side of the placement plate, and a plurality of guide cylinders are fixedly connected inside the second sliding groove. A third spring is installed in the guide cylinder. The second movable rod is fixedly connected to the third spring. In the natural state, the upper surfaces of the placement plate and the compensation plate are flush.

[0016] Optionally, a trigger rod is fixedly connected to the bottom of the pump core press-fit structure and the cap screw-on structure, and the trigger rod is adapted to the trigger groove.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above solution, by setting up a multi-station component and using a motor-driven collar to drive multiple station slots to rotate intermittently, the station slots can be accurately positioned sequentially below the feeding, pump core pressing, capping, and unloading stations, realizing continuous assembly in a production line cycle, replacing the intermittent operation of a single station, and significantly improving the production efficiency of daily chemical sprayer assembly. The overall mechanical transmission structure is simple, the positioning is accurate, and the operation is stable, making it suitable for large-scale production. The equipment layout is compact, occupies little space, and is easy to maintain in the later stages.

[0019] By setting up an adjustment component, the vertical downward pressing motion is transformed into a horizontal centering and clamping action of the adjustment clamping plate by relying on the trigger plate to drive the sliding transmission of inclined plane one and inclined plane two. The entire process is purely mechanical linkage, requiring no additional power or electronic control induction. The structure is simple, the action is synchronous and reliable, and the failure rate is low. The adjustment clamping plate has a built-in main airbag and is connected to multiple sets of auxiliary airbags on the outside through the through hole to form an overall flexible clamping structure. It can automatically adapt to daily chemical sprayer bottles of different diameters, heights and irregular contours, and is suitable for the production of various models of products. There is no need to change tooling fixtures, which greatly reduces the downtime and production cost of changeover. The airbag adopts a flexible wrap-around clamping method, with gentle and uniform contact, avoiding the problems of bottle deformation, surface scratches and damage caused by the hard squeezing of traditional rigid clamping blocks, effectively protecting the appearance quality of the workpiece.

[0020] By incorporating an anti-deviation compensation component, the placement plate stably supports the sprayer during loading and unloading, ensuring the workpiece is placed upright and facilitating precise handling and transfer by the robotic arm. During pump core pressing and capping operations, the placement plate is pushed horizontally to slide back via the compensation rod and the inclined planes of inclined plane four and three, allowing the workpiece to smoothly transition to the compensation plate above spring two for support. This achieves automatic switching of the support benchmark. The vertical elastic buffering performance of spring two effectively absorbs the impact force of the pressing assembly, preventing rigid impact damage to the pump core and bottle body. Simultaneously, in conjunction with the flexible limit of the airbag in the adjustment component, it can achieve slight horizontal adaptive coaxial correction, automatically matching the center deviation of the pressing and capping machine head, and eliminating defects such as skewed pressing, stripped caps, and uneven assembly seams.

[0033] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0034] like Figures 1 to 10As shown, an embodiment of the present invention provides a multi-station assembly device for daily chemical sprayers, including a main body 1. A multi-station component 2 is mounted on the main body 1. Above the multi-station component 2 are a pump core pressing structure 7, a capping structure 8, and two robotic arm structures 6 for loading and unloading. The multi-station component 2 drives multiple workstation slots 3. An adjustment component 4 is installed within each workstation slot 3, and an anti-deviation compensation component 5 is installed below the adjustment component 4. The multi-station component 2 drives each workstation slot 3 to rotate at the bottom of the robotic arm structures 6, the pump core pressing structure 7, and the capping structure 8, improving assembly efficiency. The adjustment component 4 automatically adjusts the size and shape of the workstation slots 3 to adapt to different types of daily chemical sprayers. The anti-deviation compensation component 5 works in conjunction with the adjustment component 4 to allow the daily chemical sprayer to adaptively follow the coaxiality adjustment of the machine head during the pressing of the pump core pressing structure 7 and the capping structure 8, avoiding increased defect rates due to rigid impact. The main body 1 integrates the multi-station component 2, the loading and unloading robotic arms, the pump core pressing structure 7, and the capping structure 8. This system forms a fully automated production line encompassing feeding, transfer, pump core pressing, capping, and unloading. Multiple workstations operate in a cyclical manner, replacing traditional single-station, single-process, intermittent assembly. This significantly shortens the assembly cycle for individual parts, making it suitable for large-scale production of daily chemical sprayers. Production efficiency is significantly improved. The workstation slot 3 has a built-in independent adjustment component 4, which automatically changes the internal dimensions and clamping configuration of the workstation slot 3. This eliminates the need for tooling changes and manual adjustments, ensuring compatibility with daily chemical sprayer products of different heights, diameters, and shapes. The equipment is applicable to a wide range of products, reducing changeover costs and downtime. It is equipped with an anti-deviation compensation component 5, which allows the sprayer workpiece to undergo adaptive micro-adjustments in coaxiality during pump core pressing and capping, preventing misalignment, jamming, and hard impacts caused by rigid assembly between the head and workpiece. This prevents damage to the sprayer housing, pump core misalignment, and capping slippage, while also reducing rigid wear on the mechanical structure of the head and workstation slot 3, extending equipment lifespan and stabilizing product yield.

[0035] like Figures 2 to 4As shown, the multi-station component 2 includes a motor 201. A collar 202 is driven and connected to the drive end of the motor 201. Multiple station slots 3 are fixedly connected to the collar 202. Each station slot 3 includes a groove body 301. A vertical sliding groove 302 is formed in the upper half of the groove body 301. A trigger plate 304 is slidably connected within the sliding groove 302, and a trigger groove 305 is provided on the trigger plate 304. A horizontal sliding groove 303 is formed in the lower half of the groove body 301. The motor 201 serves as the power source, driving the collar 202 to rotate synchronously. The collar 202 circumferentially fixes multiple station slots 3, achieving intermittent circular feeding. The transmission is uniform and stable, and the station positioning is precise, allowing for accurate stopping at the robotic arm and during pressing. Directly below the capping station, ensuring precise connection between each process, the trough 301 has a vertical slide groove 302 and a horizontal slide groove 303, providing precise limit guidance for the vertical sliding of the trigger plate 304 and the horizontal sliding of the placement plate 503, avoiding jamming or deviation during the movement, and ensuring smooth and consistent operation of the subsequent adjustment and compensation mechanisms. The trigger plate 304 can slide up and down along the slide groove 302 and has its own trigger groove 305 structure, which can be precisely matched with the trigger rod 701 at the bottom of the pump core pressing and the capping structure 8. The mechanism is automatically triggered by the mechanical pressing action, without the need to add sensors or electrical control switches, simplifying the control system, reducing failure points, and improving the stability of equipment operation.

[0036] like Figures 5 to 8As shown, the adjustment assembly 4 includes multiple inclined surfaces 401 fixedly connected to the inner side of the trigger plate 304. An inclined surface 402 is slidably connected to the bottom of the inclined surface 401. A moving rod 403 is fixedly connected to the inclined surface 402. An adjusting clamping plate 404 is fixedly connected to the moving rod 403. A main airbag 405 is installed inside the adjusting clamping plate 404. Multiple through holes 406 are provided on the main airbag 405. Multiple auxiliary airbags 407 are provided on the outer side of the adjusting clamping plate 404. The auxiliary airbags 407 communicate with the main airbag 405 through the through holes 406. Multiple springs 408 are installed in the sliding groove 302. The springs 408 are fixedly connected to the bottom of the trigger plate 304. By utilizing the sliding contact between the inclined surfaces 401 and 402 on the inner side of the trigger plate 304, the vertical downward displacement of the trigger plate 304 is converted into a horizontal inward clamping displacement between the moving rod 403 and the adjusting clamping plate 404. This is a purely mechanical linkage requiring no power. The source is simple and reliable in structure, with a fast response speed. It can automatically center and position the sprayer workpiece to avoid clamping eccentricity. The adjusting clamp 404 has a built-in main airbag 405 and multiple auxiliary airbags 407 on the outside. The main airbag 405 communicates with the auxiliary airbags 407 through the through hole 406. When clamping, the airbags flexibly expand and fit against the outer wall of the sprayer, which can not only firmly clamp without loosening, but also avoid the rigid clamp from scratching the plastic shell and damaging the appearance. At the same time, the airbags can adapt to the concave and convex and irregular bottle contours, further expanding the product compatibility range. The slide groove 302 is equipped with a spring 408 connected to the trigger plate 304. When the pump core pressing and capping process is completed, after the trigger rod 701 moves upward and disengages from the trigger groove 305, the spring 408 can automatically lift the trigger plate 304, which drives the adjusting clamp 404 to automatically release and reset. When the workstation rotates to the next process, it can be reloaded and clamped. The whole process is automatic and cyclical, without manual intervention, and is suitable for continuous automated production.

[0037] like Figures 9 to 10As shown, the anti-deviation compensation component 5 includes a second spring 501 installed at the bottom of the inner side of the workstation slot 3. A compensation plate 502 is fixedly connected to the top of the second spring 501. The anti-deviation compensation component 5 also includes a placement plate 503 that slides within the second slide groove 303. An inclined surface 3 504 is provided on the upper surface of the placement plate 503. A compensation rod 505 is fixedly connected to the bottom of the trigger plate 304. An inclined surface 4 506 is fixedly connected to the bottom of the compensation rod 505. The inclined surface 4 506 and the inclined surface 3 504 are slidably connected. A moving rod 2 507 is fixedly connected to the side of the placement plate 503. Multiple guide cylinders 508 are fixedly connected inside the slide groove 303. Springs 509 are installed in the guide cylinders 508. Moving rod 507 is fixedly connected to springs 509. In the natural state of springs 501, the upper surfaces of the placement plate 503 and the compensation plate 502 are flush. The bottom of the pump core pressing structure 7 and the capping structure 8 are fixedly connected to the trigger rod 701. The trigger rod 701 is adapted to the trigger groove 305. During the loading and unloading stage, the daily chemical sprayer is placed on the placement plate 503, which supports it stably and facilitates the stable transfer of the robotic arm. The workpiece is not easy to tilt or tip over. When the pump core is pressed in and the capping structure 8 is pressed down, the bottom trigger rod 701 and the trigger groove 305 of the trigger plate 304 precisely engage, driving the machine head to press down and synchronously driving the trigger plate 304 downward. This causes the compensation rod 505 and the inclined plane 506 to move together. The inclined plane 506 presses against the inclined plane 504, pushing the placement plate 503 to slide horizontally along the slide groove 303. This allows the bottom of the sprayer to automatically switch to be supported by the compensation plate 502 above the spring 501, relying on the spring 501 to achieve vertical elastic buffering. With the flexible clamping of the main airbag 405 and auxiliary airbag 407 of the adjustment component 4, the workpiece can be adjusted horizontally and coaxially, automatically correcting the alignment deviation between the machine head and the workpiece, avoiding rigid impact, and preventing poor assembly such as pump core press-fit offset, shell damage, and cap stripping. At the same time, the spring 3 509 can limit and buffer the placement plate 503. After the process is completed, each component automatically resets, ensuring that the benchmark is consistent for multi-station rotation operation and that the repeatability positioning accuracy is high. It is suitable for the automated continuous assembly of various specifications of daily chemical sprayers.

[0038] The working principle of the technical solution provided by this invention is as follows:

[0039] When the multi-station assembly device for this daily chemical sprayer is working, the motor 201 in the multi-station component 2 first drives the collar 202 to perform intermittent rotation. The collar 202 drives the multiple circumferentially arranged work station slots 3 to rotate in sequence, so that each work station slot 3 stops precisely under the two robotic arm structures 6, the pump core pressing structure 7 and the capping structure 8, forming a continuous feeding, assembly and unloading assembly line operation mode.

[0040] In the loading and unloading operation, the daily chemical sprayer workpiece is placed on the placement plate 503 in the work station slot 3. The upper surface of the placement plate 503 and the compensation plate 502 are flush in their natural state, providing a flat placement benchmark for the workpiece. The robotic arm structure 6 completes the automatic loading and unloading of finished products.

[0041] When the workpiece-bearing station slot 3 rotates to the bottom of the pump core pressing structure 7 or the capping structure 8, the pump core pressing structure 7 and the capping structure 8 drive the machine head to move downward. The trigger rod 701 fixed at its bottom is inserted into the trigger groove 305 of the trigger plate 304. The trigger plate 304 slides vertically downward along the slide groove 302 as the machine head presses down, compressing the spring 408 to store energy.

[0042] During the downward movement of the trigger plate 304, the inclined surface 401 fixed on its inner side moves down synchronously. Through the inclined sliding cooperation between the inclined surface 401 and the inclined surface 402, the vertical displacement is converted into the horizontal displacement of the moving rod 403, which drives the two adjusting clamps 404 to move towards each other. At the same time, the main airbag 405 and the auxiliary airbag 407 are interconnected and inflated, flexibly hugging and clamping the outer wall of the daily chemical sprayer, automatically adapting to sprayer workpieces of different specifications and shapes, and achieving centering and clamping.

[0043] At the same time, the compensation rod 505 connected to the bottom of the trigger plate 304 moves downward, causing the inclined plane 4 506 to press down and fit against the inclined plane 3 504. This drives the placement plate 503 to overcome the elastic force of the spring 3 509 and slide horizontally along the slide groove 2 303. The bottom of the workpiece is removed from the placement plate 503 and transferred to the compensation plate 502 on top of the spring 2 501. At the moment of assembly and pressing down, the spring 2 501 provides vertical elastic buffer. With the flexible clamping and limiting of the main airbag 405 and the auxiliary airbag 407 of the adjustment component 4, the daily chemical sprayer can be adjusted slightly in the horizontal direction according to the center of the head. It automatically compensates for the coaxiality deviation between the head and the workpiece and avoids assembly defects such as shell damage, pump core misalignment, and cap stripping caused by rigid impact.

[0044] After the pump core pressing and capping processes are completed, the machine head moves upward, causing the trigger rod 701 to disengage from the trigger slot 305. Under the elastic reset action of spring 1 408, spring 2 501, and spring 3 509, the trigger plate 304, adjusting clamp 404, placement plate 503, and each transmission inclined surface component automatically return to their initial positions, releasing the workpiece clamping and compensation state. Subsequently, the multi-station assembly 2 continues to rotate and enters the next workpiece cycle assembly operation.
