Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of injection molding part processing equipment, and in particular to an injection molding part automatic clamping modular integrated processing station. BACKGROUND

[0002] In the prior art, in addition to precision injection molding machine equipment and injection molding process parameters for precision injection molding part production precision control, due to various factors, injection molding parts will inevitably have burrs (also known as overflow, burr, burr, etc.), mostly occurring at the split position of the mold, which is the remaining edge of the overflow into the mold line or the gap of the mold release pin during the molding process and left on the plastic part. Therefore, in general, after the injection molding part is injection molded, manual tools are arranged to manually remove the burrs. However, for precision injection molding parts, manual burr removal cannot guarantee the consistency and stability of the appearance precision of the injection molding parts, and greatly reduces the overall production efficiency and increases the production labor cost. Moreover, injection molding manufacturers usually need to interface different customer orders and produce different types of injection molding parts, so the current enterprise designs the burr processing equipment to be specialized for a certain injection molding product, which cannot realize the universality of the equipment. For injection molding products with high appearance precision, a production line composed of multiple devices with different processing technologies needs to be designed in the burr processing process, which has low integration degree, greatly increases the production equipment cost and prolongs the production cycle, reduces the production efficiency, and occupies a large amount of production space resources. Since the burr removal of the injection molding part is mostly carried out by polishing process, a large amount of dust will be generated during the processing process, which not only affects the normal production of the workshop, but also easily causes lung diseases due to long-term inhalation of too much dust, which is harmful. The existing injection molding part burr removal processing equipment mostly does not design a dust collection mechanism, or the dust collection components are designed in a scattered layout, which cannot be efficiently integrated into the equipment and simultaneously meet the requirements of efficient dust collection and sufficient processing station space.

The injection molding part automatic clamping modular integrated processing station is modularly designed by the edge pressing mechanism, small grinding head mechanism and flexible abrasive belt polishing mechanism, and the processing function modules are installed side by side on the module mounting plate in a detachable manner. The processing function modules can be replaced simply and quickly according to the type of injection molding part and the change of processing technology, and the integrated processing of multiple different processes can be carried out on one equipment, realizing the versatility of the equipment, improving the automation production efficiency, reducing the production cost, and also ensuring the consistency and stability of the product quality. Moreover, by arranging the processing function modules side by side on the module mounting plate on the top right side of the bottom box frame, arranging the multi-joint manipulator on the manipulator mounting plate on the top left side of the bottom box frame, and arranging the dust collection mechanism between the manipulator mounting plate and the module mounting plate, a compact and reasonable integrated layout design is realized, the occupation of production space resources by the equipment is reduced, and the dedicated dust collection mechanism is integrated, so that the dust collection space and the processing space of the injection molding part are overlapped, meeting the requirement of efficient dust collection, and the side-by-side arrangement of the processing function modules also reserves sufficient processing station space for the multi-joint manipulator to drive the injection molding part on each processing function module.

[0008] Further, the left cylinder clamping mechanism includes a left cylinder mounting plate fixed to the left end of the upper cross bar, a left guide rod cylinder fixed to the left cylinder mounting plate, and a left cylinder pressing plate fixed to the output end of the left guide rod cylinder, the left cylinder pressing plate being clamped to the upper end surface of the left bottom mold plate; the right cylinder clamping mechanism is arranged at the right end of the upper cross bar and is symmetrically designed with the left cylinder clamping mechanism; the lower cylinder clamping mechanism includes a lower cylinder mounting plate fixed to the middle of the lower cross bar, and a first cylinder assembly and a second cylinder assembly fixed to the left and right sides of the lower cylinder mounting plate respectively, the first cylinder assembly includes a first lower guide rod cylinder fixed to the left side of the lower cylinder mounting plate, and a first lower cylinder pressing plate fixed to the output end of the first lower guide rod cylinder, the first lower cylinder pressing plate being clamped to the left end surface of the lower bottom mold plate, and the second cylinder assembly is symmetrically designed with the first cylinder assembly.

[0009] As can be seen from the above solutions, the left cylinder clamping mechanism fixes the left guide rod cylinder to the left end of the upper cross bar through the left cylinder mounting plate, and the left cylinder pressing plate is fixed to the output end of the left guide rod cylinder, the left guide rod cylinder drives the left cylinder pressing plate to move linearly and is clamped to the upper end surface of the left bottom mold plate, thereby automatically clamping the buckle of the injection molded part at this position; similarly, the right cylinder clamping mechanism arranged at the right end of the upper cross bar and symmetrically designed with the left cylinder clamping mechanism also automatically clamps the buckle of the injection molded part at this position; the first lower guide rod cylinder of the first cylinder assembly is fixed to the lower cross bar through the left side of the lower cylinder mounting plate of the lower cylinder clamping mechanism fixed to the middle of the lower cross bar, and the first lower cylinder pressing plate is fixed to the output end of the first lower guide rod cylinder, the first lower cylinder pressing plate being clamped to the left end surface of the lower bottom mold plate, thereby automatically clamping the buckle of the injection molded part at this position, and similarly, the second cylinder assembly fixed to the right side of the lower cylinder mounting plate is symmetrically designed with the first cylinder assembly, thereby also automatically clamping the buckle of the injection molded part at this position. Through automatic clamping of the buckles of the injection molded part in three directions, stable automatic clamping of the injection molded part is achieved.

[0010] Further, the dust collection mechanism includes a dust collection cover arranged between the mechanical arm mounting plate and the mold mounting plate, an air suction cover arranged below the dust collection cover, and a dust collector arranged in communication with the air suction cover, the air suction cover and the dust collector being arranged inside the bottom box frame.

[0011] From the above scheme, the dust collection mechanism is arranged between the manipulator mounting plate and the module mounting plate, so that a large amount of dust generated during polishing of the injection molded part on the edge pressing mechanism, the small grinding head mechanism and the flexible abrasive belt polishing mechanism can be covered and absorbed by the dust collection cover below in time. The dust enters the dust collector through the dust collection cover and the air suction cover, high-efficiency dust collection is realized, the air suction cover and the dust collector are arranged in the inside of the bottom box frame, the dust collection mechanism is completely integrated on the equipment, the component design layout is more compact, the overall space occupation of the equipment is reduced, and the polishing processing station space is not affected.

[0012] Further, the edge pressing mechanism includes an elastic pressing rod assembly, a guide shaft support and an edge pressing mounting seat, the edge pressing mounting seat is installed on the module mounting plate through positioning pins and bolts, and the elastic pressing rod assembly is fixedly connected with the edge pressing mounting seat through the guide shaft support.

[0013] From the above scheme, the edge pressing mechanism fixes the elastic pressing rod assembly for flexible rolling of the inner and outer edges of the injection molded part on the edge pressing mounting seat through the guide shaft support, so that the edge pressing mechanism is modularized, and the edge pressing mechanism is positioned between the edge pressing mounting seat and the module mounting plate through positioning pins and fastened and connected through bolts, so that the modularization and disassembly design of the edge pressing mechanism are realized.

[0014] Further, the small grinding head mechanism includes a small grinding head, a main shaft motor, a main shaft motor support and a small grinding head mounting seat, the small grinding head mounting seat is installed on the module mounting plate through positioning pins and bolts, the main shaft motor is fixed on the small grinding head mounting seat through the main shaft motor support, and the output end of the main shaft motor is connected with the small grinding head in a matched mode.

[0015] From the above scheme, the small grinding head mechanism fixes the main shaft motor on the small grinding head mounting seat through the main shaft motor support, and the small grinding head is matched with the output end of the main shaft motor, the main shaft motor drives the small grinding head to polish the inner edge of the injection molded part, so that the small grinding head mechanism is modularized, the small grinding head mechanism is positioned between the small grinding head mounting seat and the module mounting plate through positioning pins, and fastened and connected through bolts, so that the modularization and disassembly design of the small grinding head mechanism are realized.

[0016] Further, the small grinding head mechanism further includes a first dust blowing device, the first dust blowing device includes a double-shaft air cylinder fixed on one side of the main shaft motor support and having an output direction parallel to the main shaft of the main shaft motor, a gas pipe fixing block is installed at the output end of the double-shaft air cylinder, and a gas blowing pipe facing the small grinding head is arranged on the gas pipe fixing block.

[0017] From the above scheme, the first dust blowing device of the small grinding head mechanism drives the air pipe fixed block installed at the output end to make linear motion, and the air pipe is connected with the external air source. When the small grinding head mechanism completes the polishing process of the injection molded part, dust will be attached to the small grinding head, which will affect the polishing effect of the next cycle. At this time, the double-shaft air cylinder drives the air pipe to blow dust upwards and downwards to clean the small grinding head, ensuring the polishing effect of the small grinding head in each polishing cycle. After cleaning, the double-shaft air cylinder drives the air pipe to reset, which does not affect the polishing process of the injection molded part in the next cycle.

[0018] Further, the flexible abrasive belt polishing mechanism includes an abrasive belt mounting seat, an abrasive belt driven wheel set, an abrasive belt driving wheel, an abrasive belt tensioning wheel assembly, an abrasive belt, and an asynchronous motor. The abrasive belt mounting seat is installed on the module mounting plate through positioning pins and bolts. The abrasive belt driven wheel set and the abrasive belt driving wheel are both rotatably installed on the abrasive belt mounting seat and are in transmission cooperation through the abrasive belt. The asynchronous motor is fixed on the abrasive belt mounting seat and is drivingly connected with the abrasive belt driving wheel. The abrasive belt tensioning wheel assembly is slidably installed on the abrasive belt mounting seat through a sliding block and a guide rail, and is tensioned by a tension spring. The tensioning wheel rotatably installed on the abrasive belt tensioning wheel assembly tensions the abrasive belt.

[0019] As can be seen from the above scheme, the flexible abrasive belt polishing mechanism comprises a belt transmission cooperation assembly composed of the abrasive belt driven wheel set, the abrasive belt driving wheel, the abrasive belt tensioning wheel assembly, and the abrasive belt. The asynchronous motor drives the abrasive belt driving wheel to rotate and then drives the abrasive belt to polish the injection molded part. Since all the above components are installed on the abrasive belt mounting seat, the flexible abrasive belt polishing mechanism is modularized. The flexible abrasive belt polishing mechanism is positioned by the positioning pins between the abrasive belt mounting seat and the module mounting plate, and is fastened by bolts, realizing the modularized and detachable design of the flexible abrasive belt polishing mechanism.

[0020] Further, the position where the tensioning wheel is rotatably installed on the abrasive belt tensioning wheel assembly is provided with a second dust blowing device. The air pipe joint of the second dust blowing device is fixedly arranged on the back of the rotating bearing of the tensioning wheel through a joint fixing block, and a blowing hole communicating with the air pipe joint is arranged on the bearing seat of the tensioning wheel, and the blowing hole faces the contact position of the tensioning wheel and the abrasive belt.

[0021] As can be seen from the above scheme, the blowing hole arranged on the bearing seat of the tensioning wheel communicates with the air pipe joint arranged on the back of the rotating bearing of the tensioning wheel. The air pipe joint is connected with the external air source, realizing dust blowing and cleaning of the contact position of the tensioning wheel and the abrasive belt. Since the abrasive belt is driven, dust blowing and cleaning of the entire abrasive belt is realized, ensuring the polishing effect of the abrasive belt.

[0022] A further embodiment is that the flexible sanding belt grinding mechanism also includes a thin cylinder fixed on the sanding belt mounting base, the output end of the thin cylinder acting on the sanding belt tension wheel assembly, and the output direction being opposite to the tensioning direction of the tension wheel.

[0023] As can be seen from the above scheme, since sanding belts are consumable tools, when the sanding belt is severely worn and needs to be replaced, the sanding belt tensioning wheel assembly can be pushed to slide in the opposite direction of its tension by controlling the thin cylinder, so that the sanding belt can be loosened and replaced easily.

[0024] A further proposed solution is that the mounting flange of the automatic fixing fixture is connected to the multi-joint robot arm for quick positioning and quick fixing via a quick-change fixture.

[0025] As can be seen from the above scheme, the positioning and connection between the automatic fixing fixture and the multi-joint robot adopts a quick-change fixture, which can realize the rapid replacement of the automatic fixing fixture on the multi-joint robot and ensure the repeatability of the positioning accuracy between the replaced automatic fixing fixture and the multi-joint robot.

[0026] A further embodiment is that the modular integrated processing station for automatic clamping of injection molded parts also includes a quick-connect electrical box mounted on the module mounting plate. The dual-axis cylinder and the air blowing pipe of the small grinding head mechanism, the air pipe connector and the thin cylinder of the flexible sanding belt grinding mechanism are all connected to the dual unit and the external air source in sequence through the quick-connect electrical box.

[0027] As can be seen from the above scheme, the quick-connect electrical box is set on the module mounting plate and connected to the dual unit and the external air source in sequence. Therefore, pneumatic devices such as the dual-shaft cylinder, air blowing pipe, air pipe connector and thin cylinder, which are also set on the module mounting plate, can be conveniently and quickly connected to the quick-connect electrical box to realize the air supply and control of each pneumatic device.

[0028] A further improvement is that the pressing mechanism, the small grinding head mechanism, and the flexible sanding belt grinding mechanism are all equipped with protective covers.

[0029] As can be seen from the above solutions, setting up a protective box cover can achieve the functions of dust prevention, noise reduction, and safety protection. Attached Figure Description

The positioning and connection between the automatic fixing clamp 4 and the multi-joint robot 3 adopt the quick exchange clamp 31, so that the automatic fixing clamp 4 can be quickly replaced on the multi-joint robot 3, and the repeated positioning precision between the automatic fixing clamp 4 and the multi-joint robot 3 after replacement is ensured.

[0054] In the embodiment, the automatic clamping and molding integrated processing station for injection molded parts further comprises a quick-connection electrical box 12 arranged on the module mounting plate 5, and the double-shaft air cylinder 75 and the blowing pipe 77 of the small grinding head mechanism 7 and the air pipe joint 845 and the thin air cylinder 87 of the flexible sand belt polishing mechanism 8 are sequentially connected with the two-couple and external air source through the quick-connection electrical box 12. The quick-connection electrical box 12 is arranged on the module mounting plate 5 and sequentially connected with the two-couple and external air source, so that the pneumatic devices such as the double-shaft air cylinder 75, the blowing pipe 77, the air pipe joint 845 and the thin air cylinder 87 arranged on the module mounting plate 5 can be quickly and conveniently connected with the quick-connection electrical box 12, and the air source supply and control of each pneumatic device are realized.

[0055] In the embodiment, the edge pressing mechanism 6, the small grinding head mechanism 7 and the flexible sand belt polishing mechanism 8 are all provided with protective box covers. Through the arrangement of the protective box covers, the dustproof, noise reduction and safety protection effects can be achieved.
