Description

Technical Field

[0001] This invention relates to the field of precision manufacturing technology, and in particular to a metal parts processing and cleaning device. Background Technology

[0002] In precision manufacturing fields such as aerospace, high-end medical devices, precision optical components, and automotive core parts, parts must be thoroughly cleaned after processing to remove contaminants such as oil and particles. To improve automation, parts are often aligned and placed into the mounting holes of a specialized material frame before being fed into cleaning equipment as a whole. However, this production method presents two major cleaning challenges: Firstly, cleaning dead zones: When parts are in a fixed position, the areas in contact with the mounting holes (such as shoulders and side walls) are blocked. The close arrangement of parts also creates mutual shielding, making it difficult for cleaning media (liquid or gas) to effectively cover the entire surface of the parts, especially complex internal cavities, blind holes, and threads, forming stubborn cleaning dead zones.

[0003] Secondly, the risk of collisions: In order to solve the problem of dead corners, the whole material frame vibration or strong turbulent cleaning is often used. This can easily cause precision parts to collide and rub against each other in the material frame, causing irreversible damage such as scratches and deformation, which seriously affects the product yield.

[0004] Existing technologies such as high-pressure spraying and ultrasonic cleaning are insufficient to achieve thorough cleaning of aligned parts without causing damage. Therefore, there is an urgent need for a precision cleaning solution that can simultaneously meet the requirements of absolute cleanliness and absolute safety. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a metal parts processing and cleaning device, which aims to solve the problems of cleaning dead corners and impact damage in the automated cleaning process of precision parts.

[0006] This invention provides the following technical solution: A metal parts processing and cleaning device, comprising: A first spray box and a second spray box are arranged side by side. Both the first spray box and the second spray box include a box cover and a box body. The box cover is provided with a spray gun that is aligned with the parts inside the box. The bottom of the box body is provided with a drain port. A first material frame disposed in the first spray box for supporting parts arranged in a matrix, and a second material frame disposed in the second spray box for supporting parts arranged in a matrix. The first material frame includes a first tray for supporting the bottom of the part and limiting the periphery of the bottom side of the part, and a first drive unit for driving the first tray to rotate and swing. The second material frame includes a second tray for supporting the top of the part and limiting the periphery of the top side of the part, and a second drive unit for driving the second tray to rotate and swing. The transfer unit is used to pick up and transfer parts from the first material frame; The flipping unit, located between the transmission unit and the second material frame, is used to receive the parts transmitted by the transmission unit, flip them 180 degrees, and then position the parts one-to-one with the second tray.

[0007] The technical advantages of the above solution are as follows: 1. Solved the problem of cleaning dead corners: After the parts are first cleaned by "conical swing" spraying in the first spray box, the flipping unit flips the parts 180 degrees, and then the other side of the parts is cleaned by "conical swing" spraying in the second spray box. This combination of "conical swing exposing all angles" and "flipping to exchange contact areas" ensures that 100% of the outer surface of the parts can be directly and thoroughly rinsed by the cleaning medium, thus eliminating the static cleaning dead corners caused by fixed placement and mutual obstruction in principle.

[0008] 2. Achieves zero impact damage: Throughout the entire cleaning process, parts are stably supported within independent mounting holes on either the first or second tray, with their movement precisely controlled by the drive unit. During cleaning in the spray tank, parts do not come into contact with each other; during transfer, they are individually gripped by the gripper unit. This design fundamentally avoids collisions and friction between parts, perfectly protecting the surface quality of high-value precision components.

[0009] 3. Enhanced Automation and Efficiency: The parallel dual-spray box design, combined with automated transfer and flipping units, creates a continuous cleaning production line. Parts can be loaded in batches, automatically cleaned on both sides, and output, achieving efficient, automated, and continuous cleaning of batches of "aligned" parts, significantly improving production efficiency.

[0010] Preferably, both the first driving unit and the second driving unit include: A transverse mounting box and a longitudinal mounting plate, wherein the transverse mounting box is mounted on the longitudinal mounting plate along a transverse guide; Rotary and oscillating units arranged in a matrix are installed on the transverse mounting box, and each set of rotary and oscillating units is connected to a first tray or a second tray. The rotation and swing unit includes a first ball head, a ball pin sleeve, a first connecting rod, a second connecting rod, a second ball head, a ball head hinge seat, a turntable, and a center rod; The ball joint is fixedly installed on the edge of the turntable, and a second ball joint is enclosed therein; The ball pin sleeve is fixedly installed, and the first ball head is sleeved inside the ball pin sleeve; One end of the first ball head is connected to the second ball head via the second connecting rod, and the other end is connected to the first tray or the second tray via the first connecting rod; A set of central rods is provided at the center of the turntable, and the central rods are rotatably installed in the horizontal mounting box; The longitudinal mounting plate is provided with a transverse guide groove for the central rod to reciprocate laterally. The bottom of the longitudinal mounting plate is provided with a slider, which is slidably mounted in the longitudinal slide rail of the housing. The housing is provided with a longitudinal lead screw that is threadedly connected to the slider. One side of the longitudinal mounting plate is also provided with a transverse drive component for driving the transverse mounting box to reciprocate laterally.

[0011] Its technical effect is that, 1. Achieves precise and controllable complex motion: By combining "rotation (center rod driven turntable)" with "oscillation (ball joint-linkage mechanism)" and lateral and longitudinal translational drive, the tray can drive the parts to perform a complete conical oscillation motion. This composite motion can actively expose all surfaces of the parts to the spray flow.

[0012] 2. It offers flexible adjustability: The maximum amplitude of the conical pendulum is determined by the mechanical dimension of the distance between the ball joint and the center rod, providing a basic adjustment dimension for parts of different sizes. Within this maximum amplitude, the actual amplitude and direction of the conical pendulum can be precisely controlled by program-controlled lateral and longitudinal movements, resulting in strong process adaptability.

[0013] 3. Facilitates parts transfer: The drive mechanism can precisely adjust and stabilize the pallet in a horizontal position, which provides the necessary prerequisite for the grippers of the transfer unit to reliably grasp and place parts, ensuring the smooth operation of the automated process.

[0014] Preferably, the lateral drive component includes a first sealing box disposed on one side of the longitudinal mounting plate, and a set of push rods are disposed inside the first sealing box. The drive end of the push rods extends out of the first sealing box and is connected to one side of the lateral mounting box.

[0015] Its technical advantage lies in the use of a push rod to drive the horizontal mounting box, resulting in a simple and direct structure. Placing the drive component (push rod) inside the first sealed box effectively isolates the cleaning liquid, steam, or splashes that may be present in the spray box, protecting the drive component and improving the equipment's operational reliability and service life in humid environments.

[0016] Preferably, the transmission structure of the central rod includes: Each of the central rods arranged in a matrix pattern is equipped with a set of first transmission pulleys; Multiple sets of circular first conveyor belts are sequentially fitted onto the first transmission pulleys arranged in a matrix from the outside in. In addition to one set of central rods driven by the same first conveyor belt and the central set of central rods arranged in a matrix, a second pulley is also installed. A straight second conveyor belt is fitted over the second pulley; A second mounting box is also installed at the bottom of the horizontal mounting box. A rotary motor is installed inside the second mounting box. The drive end of the rotary motor is connected to one of the central rods on which the second pulley is installed.

[0017] Its technical effect is that, 1. The transmission system is simplified, reducing costs and complexity: By designing a matrix-arranged pulley system and multiple circular conveyor belts, only one rotary motor is needed to synchronously drive all the central rods in the matrix to rotate. This greatly simplifies the mechanical structure and electrical control compared to configuring a separate motor and control system for each rotary unit, reducing manufacturing costs and failure rates.

[0018] 2. Ensures motion synchronization: All center rods are linked by a rigidly connected belt drive system, ensuring that the phase and speed of all tray rotation movements are strictly synchronized, thus making the motion trajectory of all parts consistent and the cleaning effect uniform.

[0019] Preferably, a tensioning roller for tensioning the first and second conveyor belts is also provided between any two adjacent sets of center rods.

[0020] The technical advantage lies in the fact that the tension roller provides continuous and appropriate tension to both the first and second conveyor belts, effectively preventing slippage, jumping, or detachment of the belts due to slack after long-term operation. This ensures the stability and precision of the rotational power transmission, thereby guaranteeing the accuracy of the conical pendulum motion trajectory of the parts.

[0021] Preferably, the transmission unit includes: Linear overhead rails; The lifting block is slidably mounted on the linear lifting rail; A reciprocating cylinder is used to drive the lifting block to reciprocate along the linear lifting rail; A telescopic cylinder is installed at the bottom of the lifting block; A hanging plate is installed on the drive end of the telescopic cylinder; The first gripper unit, arranged in a matrix, is mounted on the hanging plate and is used to align and grip parts with the first and second trays.

[0022] Its technical advantage lies in the fact that, through the combination of linear lifting rails, reciprocating cylinders, and telescopic cylinders, the first gripper unit can move quickly and accurately in three-dimensional space. The first gripper units, distributed in a matrix and strictly aligned with the pallet, can grab or place an entire batch of parts at once, achieving efficient and damage-free parts transfer between the first spray box and the flipping unit, with high positioning accuracy.

[0023] Preferably, the flipping unit includes: Flip-up board; The second gripper units, arranged in a matrix, are mounted on the flip plate and are used to align and grip the parts with the first gripper units; A tilting cylinder, the tilting plate being mounted on its drive end; A lifting cylinder, the tilting cylinder being mounted on its drive end; A turntable, the bottom end of which is mounted on the drive end of the lifting cylinder; Its technological advantage lies in achieving a precise 180-degree rotation through a tilting cylinder, solving the core need for cleaning and changing the surface of parts. Combined with a lifting cylinder, the rotated parts can be precisely placed onto the tray of the second material frame, or retrieved from the second material frame. The turntable design further expands its functionality, enabling the tilting unit to rotate the cleaned parts and place them onto the output conveyor, completing a fully automated closed loop from cleaning to unloading.

[0024] The beneficial effects of this invention are: 1. Achieved theoretically no dead angle cleaning: The drive unit makes the parts perform a "conical pendulum" movement under the spray, actively exposing all angles; then the flipping unit makes the parts "flip over", exchanging the contact area with the tray. The two cleaning combinations ensure that 100% of the outer surface of the parts can be directly and fully acted on by the cleaning medium, fundamentally eliminating static blind spots. 2. Zero impact damage achieved: Throughout the cleaning and transfer process, the parts are securely placed in the independent placement holes of the first or second tray, and their movement is completely controlled by the drive unit. There is no hard contact or collision between the parts or between the parts and the material frame, which perfectly protects the precision surface of the parts. 3. Balancing high efficiency and flexibility: The matrix distribution design enables automated continuous cleaning of batches of parts. The parameters of the conical pendulum (such as cone angle and frequency) can be flexibly adjusted through the program. Only by changing the tray that is compatible with the shape of the parts, it can adapt to parts of different sizes and shapes, resulting in high process flexibility. 4. Especially suitable for high-value and complex parts: This solution provides an innovative and reliable technical approach to solve the ultimate cleaning problem of high-value and easily damaged parts such as precision gears, fuel nozzles, medical devices, and complex housings.

[0026] Example 1 like Figure 1-5As shown, a metal parts processing and cleaning device, in this embodiment, includes a first spray box 1 and a second spray box 2 arranged side by side. The first spray box 1 and the second spray box 2 include the same box cover 3 and box body 5. The box cover 3 is provided with spray guns 4 that are aligned with the parts in the box body 5. The bottom of the box body 5 is provided with a drain port 6. The first spray box 1 and the second spray box 2 are also provided with a first material frame 7 and a second material frame 8 for supporting parts arranged in a matrix. The first material frame 7 includes a first tray 9 for supporting the bottom of the parts and limiting the bottom periphery of the parts. The second material frame 8 includes a second tray 10 for supporting the top of the parts and limiting the top periphery of the parts. The first material frame 7 and the second material frame 8 also include a drive unit 11 for driving the first tray 9 and the second tray 10 to rotate and swing respectively.

[0027] The present invention also includes a transmission unit 19 and a flipping unit 20. The transmission unit 19 is used to transmit parts from the first material frame 7 to the flipping unit 20. The flipping unit 20 is located between the transmission unit 19 and the second material frame 8, and is used to grab and flip the received parts, and to align the flipped parts with the second tray 10 one by one.

[0028] The drive unit 11 includes a transverse mounting box 111 and a longitudinal mounting plate 112. Rotary and oscillating units 113 arranged in a matrix are mounted on the transverse mounting box 111. Each set of rotary and oscillating units 113 is connected to a first tray 9 or a second tray 10. Each rotary and oscillating unit 113 includes a first ball head 1131, a ball pin sleeve 1132, a first connecting rod 1133, a second connecting rod 1134, a second ball head 1135, and a ball head hinge seat 1136. The turntable 1137 and the center rod 1138 are connected. The ball joint 1136 is fixedly installed on the edge of the turntable 1137 and encloses a second ball head 1135. The ball pin sleeve 1132 is connected to the bottom of the housing 5 through the frame, and the first ball head 1131 is fitted inside the ball pin sleeve 1132. One end of the first ball head 1131 is connected to the second ball head 1135 through the second connecting rod 1134, and the other end of the first ball head 1131 is connected to the first ball head 1135 through the first connecting rod 1133. The turntable 1137 has a turntable 9 or a second turntable 10. A set of central rods 1138 are provided at the center of the turntable 1137. The central rods 1138 are rotatably installed in the transverse mounting box 111. The transverse mounting box 111 is mounted on the longitudinal mounting plate 112 along the transverse guide. The longitudinal mounting plate 112 is also provided with a transverse guide groove 114 for the central rods 1138 to move reciprocally in the transverse direction. The bottom of the longitudinal mounting plate 112 is provided with a slider 115. The slider 115 is slidably installed in the longitudinal slide rail 116 of the box 5. The box 5 is also provided with a longitudinal lead screw 117 screwed into the slider 115. A set of first sealing boxes 118 is provided on one side of the longitudinal mounting plate 112. A set of top rods 119 are provided in the first sealing boxes 118. The driving end of the top rods 119 passes through the first sealing boxes 118 and connects to one side of the transverse mounting box 111 to drive the transverse mounting box 111 to move reciprocally in the transverse direction.

[0029] Thus, when the horizontal, vertical, and drive center rod 1138 rotational drives are performed, the first tray 9 and the second tray 10 can be driven to complete conical pendulum motion. The "conical pendulum" actively exposes various angles and "flips" to exchange contact areas. The two combinations ensure that 100% of the outer surface of the parts can be directly and fully acted on by the cleaning medium, fundamentally eliminating static blind spots. The maximum swing amplitude is determined by the distance between the ball joint 1136 and the center rod 1138. Within this maximum swing amplitude, in conjunction with the horizontal and vertical reciprocating motion, any swing amplitude within the maximum swing amplitude can be achieved. At the same time, the first tray 9 and the second tray 10 can be kept in a horizontal position to facilitate the transfer of parts.

[0030] Furthermore, the parts are placed within the mounting holes of the first tray 9 and the second tray 10 throughout the entire process, with controlled movement and no contact between them, thus perfectly protecting the precision surfaces of the parts.

[0031] The matrix-type distribution design can also realize automated continuous cleaning of batch-aligned parts. It can adapt to parts of different shapes and sizes by simply replacing the first tray 9 and the second tray 10 and adjusting the spacing between the ball joint seat 1136 and the center rod 1138. The process is also more flexible. At the same time, by designing the matching cavity placement holes of the first tray 9 and the second tray 10, it can be better suited for cleaning high-value and complex parts.

[0032] The transmission unit 19 includes a linear suspension rail 191 and a lifting block 192 mounted on the linear suspension rail 191. The lifting block 192 is slidably mounted on the suspension rail and is driven to reciprocate along the suspension rail by a reciprocating cylinder. A set of telescopic cylinders 194 is mounted at the bottom of the lifting block 192. A set of lifting plates 195 is mounted at the driving end of the telescopic cylinders 194. First gripper units 196, arranged in a matrix and aligned with the first tray 9 and the second tray 10, are mounted on the lifting plates 195. The flipping unit 20 includes a flipping plate 201 and second gripper units 202 mounted on the flipping plate 201 and aligned with the first gripper units 196. The flipping plate 201 is mounted at the driving end of a set of flipping cylinders 203. The flipping cylinders 203 are mounted at the driving end of a lifting cylinder 204 on one side of the second spray box 2. The bottom end of the lifting cylinder 204 is mounted at the driving end of the turntable 205. Therefore, after the first gripper unit 196 has finished spraying the parts in the first spray box 1, it is driven to rise and fall by the telescopic cylinder 194 and then transferred to the top of the flipping unit 20 by the lifting block 192. Then, the second gripper unit 202 is aligned with the bottom side of the gripped parts and flipped 180°. Then, it is driven to fall and align with the second tray 10 by the lifting cylinder 204. After rising and disengaging from the second spray box 2, the box cover 3 is closed and then the parts are flipped for spraying. After the spraying is completed, the flipping unit 20 can be rotated 180° by the turntable 205 and then dropped onto the conveyor 21 on one side for output.

[0033] Example 2 like Figure 5 As shown, in this embodiment of a metal parts processing and cleaning device, to further reduce the size of the equipment, a set of first transmission pulleys 12 can be installed on each of the central rods 1138 arranged in a matrix. Multiple sets of circularly distributed first conveyor belts 13 are sequentially sleeved on the outside of the matrix-arranged first transmission pulleys 12 from the outside in. A second pulley 14 is also installed outside one set of central rods 1138 driven by the same set of first conveyor belts 13 and the outermost set of central rods 1138 in the matrix arrangement. A straight second conveyor belt 15 is sleeved on the outside of the second pulleys 14. A second mounting box 16 is also installed at the bottom of the transverse mounting box 111. A set of rotary motors 17 is installed inside the second mounting box 16. The drive end of the rotary motors 17 is connected to one set of central rods 1138 on which the second pulleys 14 are installed.

[0034] Thus, only one set of rotary motors 17 is needed to achieve synchronous rotation of the matrix-arranged center rods 1138. In order to tension the first conveyor belt 13 and the second conveyor belt 15, a tensioning roller 18 can be added between any two adjacent sets of center rods 1138.

[0035] The working principle of this invention is: 1. Loading: Place the batch of parts into the placement holes of the first tray 9 in the first spray box 1, close the box cover 3, start the spray gun 4, and at the same time drive unit 11 drives the first tray 9 to make a compound conical swing motion to spray and clean the parts facing upwards without dead angles. 2. Transfer and Flipping: After the first side is cleaned, the drive unit 11 adjusts the first tray 9 to a horizontal position. The lid 3 opens, and the first gripper unit 196 of the transfer unit 19 descends and clamps all parts. After being lifted, the parts are transported by the lifting block 192 to the top of the flipping unit 20. The second gripper unit 202 of the flipping unit 20 rises and clamps the bottom of the parts, and then the first gripper unit 196 releases. Next, the flipping cylinder 203 drives the flipping plate 201 to rotate 180 degrees, turning the parts around. 3. Flipping and Cleaning: The lifting cylinder 204 drives the flipping plate 201 to descend, precisely aligning the flipped part onto the second tray 10 of the second spray box 2. The second gripper unit 202 releases and rises away, closing the lid 3 of the second spray box 2. The drive unit 11 drives the second tray 10 to make the part perform a conical swing motion, and the spray gun 4 cleans the other side of the part (the side that was originally in contact with the first tray 9) without any blind spots. 4. Unloading: After the second cleaning is completed, the flipping unit 20 clamps the part again, the turntable 205 rotates 180 degrees, and places the part on the conveyor 21 on one side for output, completing the entire automated cleaning process.
