DETAILED DESCRIPTION

[0040] Below are all the attached Figure 1-10 The present invention is further described by way of the following embodiments:

[0041] Example 1

[0042] like Figure 1 As shown, a cleaning device for shell and cover parts of electric tools with automatic arrangement and storage function is used to clean the coolant, chips, grinding chips and other pollutants remaining on the head shell or similar parts of angle grinders, straight grinders, cutting machines, etc. The overall device includes three main parts: an external washing liquid circulation system 4, an automatic feeding system 5 and an integrated cleaning and automatic storage component 6.

[0043] The washing liquid circulation system 4 is located outside the device, and includes a hydraulic pump, a pipeline, a filtering device, etc. It provides clean washing liquid to the cleaning area through the liquid inlet pipe, and takes away the dirty washing liquid for filtration through the liquid outlet pipe. The system realizes the recycling of washing liquid.

[0044] The automatic feeding system 5 is located at the front end of the cleaning and automatic storage component 6, and is used to automatically feed the parts to be cleaned into the cleaning area to ensure that the parts are evenly stressed and accurately positioned, which is conducive to improving the cleaning efficiency.

[0045] The integrated cleaning and automatic storage component 6 contains multiple sets of directional cleaning nozzles, which can clean the incoming parts 001 at multiple angles to remove surface contaminants. During the cleaning process, the parts will be automatically collected in a regular manner by the storage device for subsequent use or packaging.

[0046] The main components of the automatic feeding system 5 include: a storage box 51, in which the parts to be cleaned 001 are stored; a reversible push plate 52 is set at the bottom to push the parts out of the storage box in batches; a bracket 54 to fix the storage box; and a second cylinder 003 to drive the storage box to rise and fall.

[0047] The front lower part and the front bottom part of the material storage box 51 are left empty for installing the cleaning and automatic storage assembly 6. The push plate 52 covers the rest of the bottom plate except the empty space, and is connected to the material storage box 51 through two rotating shafts to realize the flipping and pushing function. The side of the push plate 52 away from the rotating shaft is connected to the first cylinder 002 through a hinge to realize flipping.

[0048] The material storage box 51 and the first cylinder 002 are fixedly mounted on the bracket 54; the second cylinder 003 is fixed on the frame or wallboard (not shown), and the output end is connected to the bracket 54 to drive the entire material storage box to move up and down. In this way, the relative position of the material storage box can be adjusted according to the number of parts to meet the continuous feeding needs of the cleaning components.

[0049] like Figure 3As shown, the cleaning and automatic storage assembly 6 includes the following mechanisms:

[0050] (1) Cleaning mechanism 61: This is the area where parts are actually cleaned. It is located in the gap at the front end of the storage box 51 and is directly fixed to the frame or wall panel (not shown).

[0051] (2) The lever mechanism 62 provided on both sides is used to flip the storage surface in the cleaning mechanism 61 and to divert the unstored parts 001 at an angle.

[0052] (3) The diversion mechanism 63 at the front end is arranged between the cleaning mechanism and the material storage box, and is used to collect and temporarily store the parts diverted from the storage surface.

[0053] The automatic storage process during cleaning is as follows:

[0054] First, the empty storage box 612 is lifted by an external device and moved into the cleaning mechanism. After the storage box 612 and the grid plate 613 below it are lowered to the working position, the automatic feeding system starts to feed the parts 001 to be cleaned. At the same time, the cleaning liquid circulation system continues to supply cleaning liquid to the inside.

[0055] Under the action of the set pulse airflow, the part 001 is subjected to multi-directional impact cleaning. At the same time, some of the cleaned parts will naturally fall into the slots of the storage box 612, forming an automatic storage effect of regular arrangement.

[0056] When the storage quantity reaches the set value, the grid plate 613 rises to lift the storage box 612 and move it out of the cleaning mechanism, completing a batch of cleaning and storage.

[0057] like Figure 4 As shown, the cleaning mechanism 61 mainly includes the following components:

[0058] Cleaning tank 611: The interior of the tank is the actual cleaning area for parts. The tank walls are connected to the outside to fix the cleaning mechanism to the overall device. Reinforcement ribs can be set on the inner wall of the tank to ensure structural strength.

[0059] Storage box 612: used to hold cleaned parts. The bottom and sides of the box can be designed with sealing and diversion structures to drain excess liquid in the box and ensure that the parts are dry after storage.

[0060] Grid plate 613: supports the storage box and moves the storage box as a whole with the lifting movement. The grid plate material should be selected from lightweight and high-strength materials to reduce the system load.

[0061] Lifting shaft 614: threaded shaft structure, drivingly connected with the third cylinder 004, to realize the overall lifting of the grid plate. The shaft should be made of stainless steel.

[0062] Guide shaft 615 and guide shaft seat 616: improve lifting stability and reduce motion deviation. Combined cross arrangement is preferred.

[0063] Air nozzle 617: produces impact cleaning vortex. The number, position and angle can be optimized to improve the cleaning effect.

[0064] Observation surface 618: Made of glass or plexiglass, it is convenient for monitoring the internal storage box.

[0065] The outer plates on both sides of the cleaning pool 611 are movably sealed and assembled with the inner plates on both sides of the material storage box 51 in the automatic feeding system. This structure can narrow the gap between the two, avoid leakage of cleaning liquid, and facilitate replacement and maintenance of the cleaning system.

[0066] The sealing plate at the front upper part of the cleaning pool 611 is relatively short, forming an opening. The opening matches the shape and size of the storage box 612. The storage box 612 is a rectangular parallelepiped structure, and a movable cover is provided on the top. The cover is designed with a plurality of positioning grooves according to the shape of the parts to be cleaned 001. These positioning grooves can fix the fallen parts so that they remain neat and stable in the storage box.

[0067] When the cleaned parts naturally fall into the box through the upper opening, they can be accurately arranged in the positioning grooves. This can effectively avoid the mess during transportation. The number and size of the positioning grooves can be flexibly adjusted according to the size of the parts.

[0068] During cleaning, the storage box 612 is placed on the grid plate 613. The four corners of the grid plate 613 are fixed to the upper plane of the lifting shaft 614 by bolts. The lower end of the lifting shaft 614 passes through the shaft hole in the center of the bottom plate of the cleaning tank 611, and is threadedly connected to the output rod head of the third cylinder 004. A mechanical seal is used between the shaft hole of the bottom plate to ensure that the lifting shaft 614 slides up and down in the shaft hole while ensuring that the washing liquid does not leak.

[0069] The two ends of the top of the guide shaft 615 are screwed and locked on the opposite sides of the bottom surface of the grid plate 613. The shaft body passes downward through the bottom plate of the cleaning tank 611 and is sealed with a sealing ring. The lower end of the guide shaft 615 is inserted into the bearing on the guide shaft seat 616, and there is a light interference fit between the bearing and the shaft 615, so that the shaft 615 can slide up and down in the bearing. The guide shaft seat 616 is fixed to the mounting plate on the side of the bracket 54 with bolts.

[0070] A plurality of air nozzles 617 are obliquely inserted from top to bottom into the air nozzle holder installed on the front side plate of the cleaning tank 611, and an air seal ring is arranged in the holder. A transparent observation window 618 is arranged above the front of the air nozzle 617 to facilitate monitoring of the storage situation inside the storage box.

[0071] like Figure 5-6 As shown, the lever mechanism 62 mainly includes:

[0072] The pin 621 directly acts on the storage box to flip it. The head of the pin is a spherical surface to reduce the contact pressure with the storage box.

[0073] The pull shaft 622 is the main shaft that drives the pull pin to rotate. The lower section is a spline, which is connected to the spline gear 623. Bearings are set at both ends of the shaft to improve the smoothness of rotation.

[0074] The spline gear 623 is mounted on the lower end of the shifting shaft 622 and meshes with the rack 624. The material can be copper alloy or the like.

[0075] Rack 624: Meshes with spline gear 623 to drive it to rotate. Positioning pins are set at both ends to prevent axial movement.

[0076] Mounting base 625: fixes the rack, and the bottom is connected to the frame.

[0077] Diagonal support 626: Installed at a 45-degree angle to push the rack to move. The material can be stainless steel, etc.

[0078] Fixed plate 627: locks the diagonal brace and is fixed to the frame by bolts.

[0079] Straight support 628: an actuator for driving the movable cover of the storage box to flip.

[0080] Reset torsion spring: Installed in the semicircular grooves 009 symmetrically reserved at both ends of the shift shaft, and the torsion spring is installed to achieve the reset of the shift shaft.

[0081] The pin 621 is fixedly mounted on the upper section of the pull shaft 622. The pull shaft 622 is embedded in the semicircular groove 009 on the two side plates of the storage box 51, and is slidably matched with the shaft hole reserved in the groove. Usually, the pin 621 is hidden in the semicircular groove.

[0082] The lower section of the pull shaft 622 is a spline end, which is sleeved with a spline gear 623. The gear 623 is meshed with a rack 624 to drive the pull shaft and the pull pin to rotate. The two ends of the rack 624 can be slidably assembled in the mounting seats 625 on both sides of the bottom plate of the cleaning tank 611.

[0083] One end of the rack 624 is an inclined surface, which can slide and cooperate with the matching inclined surface of the diagonal support 626. When the diagonal support 626 rises, the inclined surface pushes the rack to move, thereby driving the gear and the shifting shaft to rotate, and the shifting pin is turned out to enter the waist hole of the storage box cover.

[0084] After the diagonal support 626 continues to rise to a certain height, the inclined surface is out of contact with the rack. At this time, the straight support 628 contacts the lower end of the shifting shaft, driving the shifting shaft and the shifting pin to continue to rise, completing the cover plate flipping.

[0085] The diagonal brace 626 and the straight brace 628 are both mounted on a fixing plate 627, and the fixing plate 627 is assembled on the output rod end of the fourth cylinder 005. The cylinder is fixed on a frame or a wall plate (not shown).

[0086] like Figure 7 As shown, the diversion mechanism 63 includes a diversion chamber 631, a gate 632 for controlling the retention of part 001 in the diversion chamber 631, a compression spring 633 for regulating the stroke of the gate 632, a compression spring shaft 634 for guiding the compression spring 633, a fixing seat 635 for installing the compression spring shaft 634, and an opening and closing cylinder 010 for controlling the opening and closing of the gate 632.

[0087] The flow dividing chamber 631 is a closed U-shaped trough body, which is covered at the front opening of the cleaning tank 611. The internal partition plate 011 divides it into two upper and lower channels, the upper channel is the parts inlet, and the lower channel is the outlet.

[0088] A gate 632 is installed at the exit, which is usually in a closed state by default. The two ends of the bottom of the gate 632 are assembled on the fixed seat 635 through a compression spring 633 and a compression spring shaft 634. A special opening and closing cylinder 010 is also provided for controlling the opening and closing of the gate.

[0089] Before work, the opening and closing cylinder 010 starts before cleaning, driving the gate 632 to open the outlet channel. This will release the reserved parts in the diversion chamber to flow back to the cleaning pool and re-participate in this cleaning collection. After cleaning, the opening and closing cylinder 610 closes the gate and waits for the next working cycle to open it again.

[0090] With reference to all the accompanying drawings;

[0091] 1. System Pre-configuration Phase:

[0092] The conveying system transfers the parts to be cleaned to the storage box;

[0093] The cleaning liquid circulation system injects cleaning liquid into the cleaning tank;

[0094] The external gripping mechanism grabs the empty storage box and places it on the grid plate in the cleaning tank.

[0095] 2. Cleaning operation stage:

[0096] The cylinder drives the material storage box to rise and fall, and transfer the parts to the appropriate height;

[0097] The cylinder drives the push plate to push the appropriate amount of parts into the cleaning tank;

[0098] The air nozzle generates a pulse cleaning vortex, and the parts are tumbled and cleaned under the action of the vortex. At the same time, the vortex impacts the parts to achieve the cleaning purpose and drive the parts to tumble up and down in the cleaning solution. When the airflow is paused, the parts will fall into the fixed groove on the lid of the storage box. The fixed groove is made according to the most stable orientation of the parts. Therefore, when the airflow is started again, the parts that fall into the fixed groove in a certain orientation will no longer be locked with the movement of the vortex, while the parts that fall into the fixed groove in other orientations will be rolled up by the vortex again because of the mismatch in contact and continue to tumble up and down until they enter the fixed groove in a certain orientation and are locked;

[0099] The visual system monitors the locking status inside the storage box and closes the air nozzle when it is fully loaded.

[0100] 3. Storage and flipping stage:

[0101] The cylinder drives the grid plate to rise, driving the storage box into the diversion area, and the gate closes;

[0102] The cylinder drives the diagonal support to push the lever mechanism to work and flip the storage box cover;

[0103] The remaining parts slide from the cover plate into the diversion chamber for temporary storage.

[0104] 4. Uninstallation phase:

[0105] An external gripper mechanism removes the fully loaded parts bin from the system;

[0106] Complete a complete cleaning and storage cycle.
