Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of trimming equipment for injection molded workpieces, and in particular to a trimming machine. BACKGROUND

[0002] Workpieces formed by injection molding often have excess waste edges and excess waste material designed to match the injection flow channel, and the waste edges and excess waste material of the workpieces need to be removed before the workpieces can be packaged.

[0003] A common removal method is to remove the waste edges and waste material of the workpieces by a trimming machine. For non-cylindrical workpieces, regular shapes are usually cut off by a cutting mold, and irregular shapes are usually removed by polishing.

[0004] For cylindrical workpieces, the workpieces are usually fixed on a rotating table and then the waste edges and waste material of the workpieces are cut off by a cutter.

[0005] In order to avoid interference with the workpieces, the cutter is usually designed as a rod, and in order to ensure that the transition between the cut surface of the waste edge or waste material and the surface of the workpiece is smooth without steps, the cutter tip used for cutting is designed as multiple surfaces.

[0006] During long-term use, the cutter will become blunt due to wear and tear and needs to be removed and polished before it can be used again. Since the cutter tip has multiple surfaces, the cutter needs to be adjusted to the correct angle after being reinstalled after polishing before it can cut normally, so the cutter needs to be loosened and fixed multiple times during adjustment, and multiple test cuts also need to be performed to adjust the cutter to the appropriate angle, and the overall adjustment process is relatively cumbersome. SUMMARY

[0007] In order to solve the problem of the cutter of the conventional trimming machine being relatively cumbersome to reinstall after being removed and polished, the present application provides a trimming machine.

[0024] The material taking member is arranged on the lifting frame and is used to take and place the workpiece.

[0025] The material taking member is transported to a position where the material taking member can take the material on the feeding conveyor belt and the workbench by sliding the translation frame and lifting the lifting frame.

[0027] Optionally, the frame is slidably installed with a mounting plate in the direction of approaching or moving away from the feeding end of the discharge conveyor belt, and the mounting plate is rotatably installed with a second vacuum suction cup, when the mounting plate slides to the feeding end of the discharge conveyor belt, the second vacuum suction cup is located above the feeding end of the discharge conveyor belt, and at this time when the material taking device places the workpiece on the discharge conveyor belt, the second vacuum suction cup is used to receive the workpiece and place the workpiece on the discharge conveyor belt after turning over.

[0028] Optionally, the frame between the workbench and the feeding conveyor belt is provided with a temporary storage table for placing the workpiece, and when the transport frame, the lifting frame and the material taking device cooperate to transport the workpiece, the workpiece is simultaneously conveyed from the feeding conveyor belt to the temporary storage table, from the temporary storage table to the workbench, and from the workbench to the discharge conveyor belt.

[0029] Optionally, the workbench comprises a rotating table rotatably installed on the frame, a connecting shaft rotatably installed on the frame, and a rotary joint, one end of the connecting shaft is coaxially connected with the rotating table, the connecting shaft is tubular, the coaxially arranged annular negative pressure groove of the table top of the rotating table is coaxially provided with a negative pressure hole, the rotating table is internally provided with a plurality of air channels, the negative pressure groove and the negative pressure hole are connected and communicated with the inner hole of the connecting shaft through the air channels, and the rotary joint is coaxially arranged on the end of the connecting shaft away from the rotating table, and the rotary joint is used to connect the air pump.

[0030] Optionally, the tool holder comprises a first support arranged on the frame, the first support is slidably installed with a second support, the second support is horizontally slidably installed with a third support, the third support is rotatably installed with a fourth support, the rotation axis of the fourth support is horizontal, one end of the fourth support is rotatable to face the workbench, the fourth support is slidably installed with a fifth support, the fifth support can slide to the end of the fourth support close to the workbench, and the tool holder is rotatably installed on the fifth support.

[0032] In summary, after the cutter is polished and reinstalled on the cutter holder, the cutter tip angle is adjusted to the appropriate angle by rotating the cutter holder, and the cutter holder is fixed by the fixing member to complete the adjustment of the cutter. Compared with the traditional method of loosening the cutter fixing structure multiple times, rotating the cutter, and then fixing the cutter with the cutter fixing structure, the cutter adjustment is more convenient, and the problem of cutter deflection after traditional cutter adjustment and fixing is less likely to occur. When cutting off the waste edge of a cylindrical workpiece made of flexible material, the workpiece is limited by the limiting plate. Only when the waste edge is of normal thickness, the first vacuum chuck can take out the workpiece from the feeding conveyor under the limitation of the limiting plate. When the waste edge of the workpiece is too thick, causing excessive resistance, the first vacuum chuck cannot successfully take out the workpiece. The central processing unit detects the abnormal change of the internal pressure of the first vacuum chuck, stops transporting the workpiece, resets the translation frame and the lifting frame, and then commands the limiting plate to move away from the feeding conveyor. After that, the feeding conveyor is started to push the abnormal workpiece off the feeding conveyor. Then, the limiting plate is reset to normally transport the workpiece. Due to the detection of the limiting plate, most abnormal workpieces can be detected before cutting, reducing false alarms caused by abnormalities in the workpiece itself during subsequent detection of the workpiece. In addition, since the temporary table is provided, the moving stroke of the translation frame is reduced, the overall size of the equipment is reduced, and the transportation speed of the workpiece is improved.

[0087] Referring to Figure 14 and Figure 15 When the cutter is installed, first, the cutter is inserted into the spring collet 53 and the end of the cutter abuts against the hole bottom of the second connecting hole 831, and the collet of the spring collet 53 is tightened until the friction between the cutter and the spring collet 53 can prevent the cutter from slipping out of the spring collet 53 under the action of gravity.

[0088] Referring to Figure 14 and Figure 15 Then, the workpiece to be processed is sleeved on the workbench 3, the rack 87 is pushed to drive the driving gear 84 to rotate, thereby driving the driving rod 82 to rotate, because the cutter limits the rotation of the adjusting block 83, the driving rod 82 drives the adjusting block 83 to slide when rotating, thereby driving the cutter to slide until the cutting edge of the cutter abuts against the workpiece, and then the workpiece is taken out. The side wall of the rack 87 is provided with a scale 871 corresponding to the sliding distance of the adjusting block 83, after the workpiece is taken out, the rack 87 is continuously pushed to slide to drive the driving gear 84 to rotate and drive the adjusting block 83 and the cutter to slide for a specified cutting distance, and then stop. The cutting distance refers to the extension distance of the cutter after abutting against the workpiece until the waste edge of the workpiece can be cut off without damaging the workpiece.

[0089] The extension length of the cutter can be conveniently and accurately adjusted through the cooperation between the driving mechanism and the adjusting block 83, and the axial position of the cutter in the use process is not prone to change through the axial support force provided by the adjusting block 83 to the cutter.

[0090] Referring to Figure 14 and Figure 15 After the extension distance of the cutter is adjusted, the limiting block 88 is disassembled, and then the rack 87 is taken out to complete the adjustment. The side wall of the connecting base is also provided with a cover, the cover is embedded in the slot of the mounting groove 86 in cooperation to close the mounting groove 86, when the rack 87 is taken out, the cover is mounted on the side wall of the connecting base to close the mounting groove 86, so that the driving rod 82 and the driving gear 84 are not prone to rust and are not prone to be disturbed to rotate by the outside world to cause the position of the cutter to deviate.

[0091] When the cutting surface of the workpiece is located on the side wall of the workpiece, the camera 61 can obtain a photo that can be used for contrast detection by shooting from the upper side of the workpiece. However, when the cutting surface of the workpiece is located on the bottom wall of the workpiece, the photo obtained by shooting from the upper side of the workpiece cannot reflect the complete cutting surface of the workpiece.

[0092] The mounting plate 12 is horizontally slidably installed on the rack 1 along the direction close to or away from the feeding end of the discharge conveying belt 22, the mounting plate 12 is fixedly installed with a turnover motor, the output shaft of the turnover motor is horizontal, and the output shaft of the turnover motor is coaxially fixedly installed with a second vacuum chuck 121.

When the piston rod of the lifting cylinder 241 is retracted, the third vacuum chuck can be used to adsorb the workpiece of the second vacuum chuck 121, and when the piston rod of the lifting cylinder 241 is extended, the third first vacuum chuck 251 can be used to adsorb the workpiece of the workbench 3.

[0094] Referring to Figure 1 , Figure 3 and Figure 7 , the mounting plate 12 is also driven by the cylinder, when the piston rod of the cylinder is extended to push the mounting plate 12 to slide close to the feeding end of the discharge conveying belt 22, the second vacuum chuck 121 is located directly above the feeding end of the discharge conveying belt 22. At this time, the piston rod of the lifting cylinder 241 is retracted, when the sliding frame 23 slides away from the feeding conveying belt 21 and the lifting frame 24 descends to the bottom end, the third first vacuum chuck 251 places the workpiece on the second vacuum chuck 121.

[0095] Referring to Figure 1 , Figure 3 and Figure 7 , when the first vacuum chuck 251 stops, the second vacuum chuck 121 starts to fix the workpiece after machining on the second vacuum chuck 121, and then the turnover motor starts to turn over the second vacuum chuck 121, so that the workpiece faces the discharge conveying belt 22, the second vacuum chuck 121 stops, and the workpiece is turned over and falls onto the discharge conveying belt 22, and then is conveyed to the detection device 6 for detection.

[0096] By turning over the workpiece, the cutting surface of the workpiece is located on the top wall of the workpiece, so that the camera 61 can completely shoot the cutting surface of the workpiece.

[0097] Referring to Figure 3 and Figure 4The rack 1 is horizontally slidably installed with a limiting plate 11 along the conveying direction of the feeding conveying belt 21, the limiting plate 11 slides along the direction of approaching or moving away from the feeding conveying belt 21, and the limiting plate 11 is driven by a pneumatic cylinder.

[0098] Referring to Figure 3 and Figure 4 When the piston rod of the pneumatic cylinder is extended, the limiting plate 11 slides to the position directly above the discharging end of the feeding conveying belt 21, and the limiting plate 11 is provided with a limiting groove in the shape of an isosceles triangle facing the direction of the feeding end of the feeding conveying belt 21.

[0099] Referring to Figure 3 and Figure 4 When the workpiece made of flexible material, such as rubber or silica gel, is processed, the limiting plate 11 is driven by the pneumatic cylinder to move to the discharging end of the feeding conveying belt 21, and when the feeding conveying belt 21 transports the workpiece to the designated position, the side wall of the workpiece is in contact with the side wall of the limiting groove, and the scrap edge of the workpiece is located below the limiting plate 11.

[0100] Referring to Figure 3 and Figure 4 When the workpiece is sucked by the first vacuum chuck 251, the first vacuum chuck 251 needs to pull the scrap edge of the workpiece out from below the limiting plate 11 to successfully take the workpiece out of the feeding conveying belt 21, if the workpiece has defects, resulting in a too thick scrap edge or insufficient sealing between the workpiece and the first vacuum chuck 251, the first vacuum chuck 251 will not be able to take the workpiece out of the feeding conveying belt 21, when the central processing unit detects that the change in air pressure in the first vacuum chuck 251 is always in an abnormal state, it can be judged that the workpiece is a defective product, at this time the pneumatic cylinder drives the limiting plate 11 to slide away from the feeding conveying belt 21, the feeding conveying belt 21 continues to start to push the defective workpiece off the feeding conveying belt 21, and then the limiting plate 11 is reset.

[0101] Referring to Figure 3 and Figure 4 Through the cooperation between the limiting plate 11 and the first vacuum chuck 251, the workpiece can be conveniently preliminarily detected, and the overall detection process is relatively simple.

[0102] The limiting plate 11 is fixedly installed with a proximity sensor, which detects the position of the workpiece and counts at the same time, and when the proximity sensor detects that the workpiece reaches the designated position, the central processing unit stops the feeding conveying belt 21, so that the feeding conveying belt 21 is not easy to cause the distance between two workpieces to gradually shorten and cause the workpieces to be stacked with each other due to mechanical errors during the transportation of the workpieces. At the same time, the proximity sensor realizes feeding monitoring, which is convenient for subsequent maintenance when a fault occurs.

[0104] When the workpiece waste edge and the internal cover are cut, the push plate 14 is lifted to push the waste edge from the rotating table 31, and the suction pump reversely fills air to blow the cut cover from the rotating table 31, and then the jet holes 72 jet to blow the waste material.

[0105] The embodiment of the edge trimmer provided by the application has the following advantages:

[0106] After the workpiece to be processed is transported to the limiting plate 11 through the feeding conveying belt 21, the feeding conveying belt 21 is stopped, then the sliding frame 23 is slid to the discharging end of the feeding conveying belt 21, the lifting frame 24 is lowered to suck the workpiece through the first vacuum suction disc 251, the sliding frame 23 is reset, and the lifting frame 24 is lowered to place the workpiece on the temporary storage table 13.

[0107] After the above process is repeated, the workpiece is placed on the workbench 3, the third vacuum suction disc is started to adsorb the workpiece on the workbench 3, the workbench 3 is rotated under the drive of the motor, the feed motor is started to push the cutter to the specified position to cut off the waste edge of the workpiece, then the feed motor is retreated, and then the sliding frame 23, the lifting frame 24 and the first vacuum suction disc 251 repeat the above process to place the workpiece on the discharging conveying belt 22 to discharge, and the discharging conveying belt 22 transports the workpiece to the camera 61 to take a picture.
