Detailed Implementation

[0031] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0032] like Figure 1-10As shown, a cleaning and transfer device for a coupling production line includes: a cleaning mechanism 1 and a transfer mechanism 2 for receiving workpieces cleaned by the cleaning mechanism 1. The cleaning mechanism 1 includes: a cleaning chamber 11, and a flushing cleaning section 12 for cleaning the surface of the workpiece and for correcting the posture of the workpiece is provided inside the cleaning chamber 11. The flushing cleaning section 12 includes: a first cleaning section 121, and a second cleaning section 122 are disposed opposite to each other on the inner wall of the cleaning chamber 11. The water outlet end faces of the first cleaning section 121 and the second cleaning section 122 are provided with cleaning ports 123 arranged in a rectangular array. A slide table 4 for smooth movement of the workpiece is provided between the cleaning mechanism 1 and the transfer mechanism 2.

[0033] The cleaning chamber 11 includes a baffle plate 111, a fixed plate 112, an I-beam plate 113, and a movable plate 114. The two baffle plates 111, I-beam plates 113, and movable plates 114 are connected and fitted together to form a shell structure with openings at the top and bottom. The movable plate 114 is hinged at the discharge port of the cleaning chamber 11. The baffle plate 111 and the I-beam plate 113 are mounted on the fixed plate 112, and the fixed plate 112 is mounted on the frame.

[0034] A U-shaped block 115 is provided on the baffle plate 111. A support shaft 116 is rotatably installed inside the U-shaped block 115. A cover plate 117 is provided on the U-shaped block 115 to prevent the support shaft 116 from detaching from the U-shaped block 115. The other end of the support shaft 116 is fixedly connected to the movable plate 114, so that the movable plate 114 can swing freely.

[0035] The inner wall of the baffle plate 111 is provided with a groove for installing the first cleaning part 121 and the second cleaning part 122. The first cleaning part 121 and the second cleaning part 122 are fixed in the groove by bolts and sealed by a sealing ring. The baffle plate 111 is provided with an independent water channel. Each row of cleaning ports 123 on the first cleaning part 121 and the second cleaning part 122 is connected by an independent water channel. Each independent water channel is provided with a solenoid valve at the inlet for independent control. The baffle plate 111 also includes a water tank 3, which is connected to the independent water channel by a pipe and is supplied with water by a water pump.

[0036] This application solves the problem of incorrect positioning caused by the non-end face of the workpiece contacting the bottom when it falls into the cleaning chamber 11, which leads to the workpiece rolling when passing the slide table 4 and making it impossible to control the transport of the workpiece normally by setting up a flushing cleaning section 12. The water channels sprayed from the cleaning ports 123 on the first cleaning section 121 and the second cleaning section 122 are perpendicular to the first cleaning section 121 and the second cleaning section 122. Therefore, when the workpiece is in an abnormal state, water column pressure is applied to the upper and lower ends of the workpiece at the same time, which can drive the workpiece to twist and adjust the abnormal state of the workpiece. The adjusted workpiece can be smoothly transported to the transfer mechanism 2 through the slide table.

[0037] The bottom of the cleaning chamber 11 is provided with a drainage structure 13, which includes a horizontal column 131. The horizontal column 131 is located at the bottom of the cleaning chamber 11, and multiple horizontal columns 131 are arranged parallel to each other. The axial direction of the horizontal column 131 is the direction of movement of the workpiece. The horizontal column 131 can be fixed to the bottom of the cleaning chamber 11 individually, or it can be installed at the bottom of the cleaning chamber 11 after being integrated with a frame. The function of the horizontal column 131 is to support the parts and prevent them from falling. Its shape is not limited to columnar shape, but can be other shapes or structures, such as screens, prisms, etc. The fixing plate 112 is provided with a positioning groove 132 for positioning the horizontal column 131. The two ends of the horizontal column 131 are placed in the positioning groove 132 and are pressed and fixed by a V-shaped strip 133. The V-shaped strip 133 is located in the groove of the I-beam plate 113.

[0038] The cleaning chamber 11 further includes a workpiece ejection mechanism 14, which moves the workpiece from the discharge port of the cleaning chamber 11 to the transfer mechanism 2. The workpiece ejection mechanism 14 includes a linear motion mechanism 141, which is mounted on a frame. A T-shaped plate 142 is provided at the output end of the linear motion mechanism 141. Multiple uprights 146 are provided on the T-shaped plate 142, spaced apart and matched in position to the horizontal column 131. The column 146 passes between the two horizontal columns 131 and is placed inside the cleaning chamber 11. The direction of movement of the column 146 is consistent with the direction of arrangement of the horizontal columns 131. A partition plate 143 is provided between the T-shaped plate 142 and the output end of the linear motion mechanism 141. The column 146 also includes a guide rail 144, which is mounted on the fixed plate 112. A slider 145 is provided on the guide rail 144. The slider 145 is mounted on the partition plate 143 through a connecting block 147, thereby improving the stability of the column 146 during movement.

[0039] Below the drain structure 13, a water collection structure 15 and a water spraying structure 16 are provided. The water spraying structure 16 is placed between the water collection structure 15 and the drain structure 13 to filter large particles. The water spraying structure 16 includes: a water spraying bracket 161, on which a water collection funnel 151 is installed. A water spraying net 162 is detachably or fixedly installed on the water collection funnel 151 to filter large particles. A water collection pipe 152 is provided at the lower end of the water collection funnel 151 to facilitate centralized collection of wastewater, or the water collection pipe 152 is connected to a water tank.

[0040] The transfer mechanism 2 includes: a motor 202, which is mounted on a motor support 206. A bearing 205 is housed within the motor support 206. The outer diameter and one end face of the bearing 205 are in contact with the motor support 206. An elastic retaining ring is provided on the other side of the bearing 205 to prevent axial movement. The motor support 202 is fixed to a profile frame 201. The bore end of the motor 202 is aligned with the drive shaft 204. A keyway is provided on one side of the drive shaft 204, and a keyway is also provided inside the motor 202. The motor 202 transmits power and torque to the drive shaft 204 via a flat key 203. A bearing 205 and an elastic retaining ring 207 are also housed within the bearing 205 housing. The bearings 205 on both sides support the drive shaft 204. The extension block 212 is connected to the profile frame 201 on one side, and an adjusting screw 213 is provided on the other side. The adjusting shaft 214 is set in the slot of the extension block 212 on both sides. The adjusting screw 213 is threadedly connected to the adjusting shaft 214. The position of the adjusting shaft 214 in the lateral direction is adjusted by tightening or loosening the adjusting screw 213, so as to adjust the tension of the belt 216. Bearings 205 are provided on both sides of the adjusting shaft 214. The inner hole of the bearing 205 fits with the outer circle of the adjusting shaft 214, and the outer circle of the bearing 205 fits with the inner hole of the driven shaft 215. The adjusting shaft 214 and the driven shaft 215 coincide. A mandrel frame 222 is provided in the middle of the profile frame 201. The mandrel 223 is set in the mandrel frame 222 on both sides to prevent the middle of the belt 216 from collapsing. A support plate 217 is provided on the top of the profile frame 201. The belt 216 is located on the pallet 217. Several baffles 218 are provided on both sides of the pallet 217 and the belt 216 to prevent the workpiece from detaching from the belt 216. A first height limit plate 21 is provided on the left side of the profile frame 201, between the two baffles 218 on the left. A second height limit plate 22 is provided on the right side of the profile frame 201. The first height limit plate 21 and the second height limit plate 22 together form a height limit plate to prevent the workpiece from tipping over when the end face of the workpiece is not in contact with the belt 216. The second height limit plate 22 is located at the end of the two baffles 218 and is in contact with them. A guide plate 23 is provided on the profile frame 201 to adjust the position of the workpiece on the transfer mechanism 2. One side is in contact with the second height limit plate 22, and the other side is in contact with one of the baffles. 218 is fitted, causing the workpiece to move laterally closer to the center of the belt 216; the limiting plate 24 is installed at the front end of the profile frame 201, and the V-shaped groove 25 of the limiting plate 24 ensures that the position of the workpiece is consistent each time it is conveyed. The opening direction of the V-shaped groove 25 corresponds to the trajectory direction of the workpiece after it is guided by the guide plate 23; the adapter plate 208 is fixed on the bearing seat 211 and the motor support seat 206 respectively. The other side of the adapter plate 208 is connected to the connecting plate 209, and the connecting plate 209 is equipped with a sensor 210. The sensors 210 are distributed on both sides of the limiting plate 24. When the workpiece fits with the V-shaped structure of the limiting plate 24, the sensor 210 receives a signal, indicating that the workpiece has reached the designated position and can proceed to the next process. At the same time, the motor 202 stops running.The water receiving tank 224 is located below the mandrel 223 and is fixedly connected to the profile frame 201 to prevent water stains on the workpiece from dripping onto the ground.

[0041] The transfer mechanism 2 is provided with a first height limiting plate 21 and a second height limiting plate 22 for assisting in adjusting the workpiece's posture. The first height limiting plate 21 and the second height limiting plate 22 have the same structure.

[0042] This application does not mention a control system, as the control system is not the focus of this application and is therefore not disclosed. Any control system that can achieve the corresponding function of this application is acceptable.

[0043] A cleaning and transfer method for a cleaning and transfer device used in a coupling production line includes the following steps:

[0044] Step 1: The workpiece processed by the CNC lathe falls onto the draining structure 13 inside the cleaning chamber 11;

[0045] Step 2: The cleaning ports 123 on the first cleaning section 121 release high-pressure water row by row from bottom to top. At the same time, the cleaning ports 123 on the second cleaning section 122 release high-pressure water row by row from top to bottom. The two form a high-pressure counter-current to clean the workpiece of the non-end face contact drainage structure 13 while performing posture correction.

[0046] Step 3: After the workpiece is cleaned and straightened, the cleaned workpiece is pushed out of the cleaning chamber 11 by the workpiece ejection mechanism 14 and moved to the transfer mechanism 2.

[0047] Step 4: The first height limit plate 21 and the second height limit plate 22 on the transfer mechanism 2 respectively perform auxiliary posture adjustment on the workpieces that have not completed posture correction.

[0048] When using this invention,

[0049] After the CNC lathe finishes machining the workpiece, the workpiece falls onto the horizontal column 131 in the cleaning chamber 11. Water from the water tank 3 enters the baffle plate 111 through a water pump and is sprayed out from top to bottom and from bottom to top through the cleaning ports 123 on the first cleaning section 121 and the second cleaning section 122, respectively, to clean the cutting fluid and chips from the surface of the workpiece and to correct any abnormal posture of the workpiece. The baffle plate 111, the I-beam plate 113, and the movable plate 114 surround the workpiece to prevent liquid from spraying into the external space. After cleaning, the linear motion mechanism 141 drives the vertical column... The column 146 pushes the workpiece to move laterally on the horizontal column 131. When it passes the movable plate 114, the water flow is automatically shut off. The column 146 lifts the movable plate 114, causing the movable plate 114 to rotate. The column 146 continues to push the workpiece to move laterally until the workpiece falls onto the conveying mechanism 2. The water sprayed from the first cleaning section 121 and the second cleaning section 122 flows through the water spray net 162 into the water collection funnel 151 on the water spray bracket 161, and then flows back into the water tank 3 through the water collection pipe 152, so that the water used for cleaning can be recycled or collected and treated centrally.

[0050] The workpiece falls from the cleaning mechanism 1 onto the belt 216. The motor 202 transmits power and torque to the drive shaft 204 via the key 203. The rotation of the drive shaft 204 drives the driven shaft 215 to rotate and the belt 216 to move laterally. The workpiece moves laterally with the belt 216. When the workpiece passes the height limit plate, if the end face of the workpiece is not in contact with the belt, the height limit plate will cause the workpiece to tilt until its end face is in contact with the belt 216. When the workpiece passes the guide plate 23, the distance between the bottom plane of the guide plate 23 and the belt 216 is less than the outer diameter of the workpiece. This setting adds a measure to keep the workpiece in the same posture. When the workpiece reaches the V-groove 25 of the limit plate 24, the sensor 210 sends a signal. At this time, the motor 202 stops running and transmits the signal that the workpiece has reached the designated position to the next process.

[0051] The preferred embodiments of the invention have been described in detail above with reference to the accompanying drawings. However, the invention is not limited to the specific details of the above embodiments. Within the scope of the inventive concept, various equivalent transformations can be made to the technical solutions of the invention, and all such equivalent transformations fall within the protection scope of the invention.
