[0049] The following is combined with Figure 1-Figure 14 This application is described in further detail.

[0050] The embodiment of the present application discloses a part nozzle removal device 100 .

[0051] Reference Figure 1-Figure 3 , Figure 8 and Fig.10 According to the embodiment of the present application, the part nozzle removal device 100 includes: a punching device 1, a nozzle limiting device 2 and a twisting device 3. The punching device 1 includes a tool 11, and the tool 11 is arranged relative to the joint between the part and the injection nozzle. When the tool 11 is driven, the tool 11 moves close to the joint to punch and reduce the thickness of the joint. That is to say, the tool 11 cuts off a part of the joint between the part and the injection nozzle, which can avoid the thickness of the joint between the part and the injection nozzle being too large, thereby reducing the subsequent processing difficulty of separating the part from the injection nozzle. After the tool 11 completes the punching work, the tool 11 is driven to move away from the joint. It should be noted that when the tool 11 completes the punching work, the part and the injection nozzle are not completely separated, and the thickness of the joint is very small.

[0052] Furthermore, there can be multiple tools 11. When multiple parts are formed by one injection molding, there are multiple joints between the parts and the injection nozzle. The multiple joints and the multiple tools 11 are spaced apart along the radial direction of the parts, and the multiple joints and the multiple tools 11 are arranged in a one-to-one correspondence. The multiple tools 11 are driven simultaneously to punch the corresponding joints, thereby achieving the technical effect of simultaneously processing multiple joints.

[0053] Furthermore, the joint portion may be located between two cutters 11 , and the two cutters 11 respectively punch the side of the joint portion opposite to the cutter 11 . Such an arrangement may reduce the working time of the cutter 11 punching the joint portion, and may improve the working efficiency of the punching device 1 .

[0054] The water outlet limiting device 2 is used to limit the injection water outlet. By setting the water outlet limiting device 2 to limit the injection water outlet, it can be avoided that when the part and the injection water outlet are separated, the part drives the injection water outlet to move, resulting in the inability to separate the part and the injection water outlet, thereby improving the working reliability of the part water outlet removal device 100.

[0055] In some specific embodiments, the nozzle limiting device 2 can limit the injection nozzle by clamping the injection nozzle. In other specific embodiments, the nozzle limiting device 2 can limit the injection nozzle by adsorbing the injection nozzle.

[0056] The torsion device 3 includes a mounting frame 31, a first clamping assembly 32 and a first driving assembly 33. The first driving assembly 33 is connected and matched with the mounting frame 31. The first driving assembly 33 and the first clamping assembly 32 are in transmission connection. Specifically, along the second direction of the torsion device 3, the first driving assembly 33 is connected and matched with the front end wall of the mounting frame 31. Along the height direction of the torsion device 3, the first clamping assembly 32 is located below the first driving assembly 33. The second direction of the torsion device 3 can refer to Figure 1 The front-to-back direction in the torsion device 3 can be referred to as Figure 1 The up and down directions in .

[0057] Furthermore, the first clamping assembly 32 includes a first jaw group 321, which is used to clamp the circumferential edge of the part, and the first driving assembly 33 is used to drive the first clamping assembly 32 to rotate around the pivot axis of the first clamping assembly 32 so that the part and the injection nozzle are twisted and separated from each other.

[0058] Specifically, the first clamping jaw group 321 is used to clamp parts from the parts feeding equipment. After the first clamping jaw group 321 completes the part clamping, the nozzle limiting device 2 limits the injection nozzle, and the first driving assembly 33 drives the first clamping assembly 32 to rotate. The part and the injection nozzle rotate relative to each other and the joint between the part and the injection nozzle is twisted off, thereby achieving the technical effect of separating the injection nozzle and the part.

[0059] After the part and the injection nozzle are separated, the first clamping jaw group 321 releases the part, the nozzle limiting device 2 releases the injection nozzle, and then the first clamping jaw group 321 clamps the part again, and the nozzle limiting device 2 limits the injection nozzle again, thereby achieving the technical effect of cyclically separating multiple parts and corresponding injection nozzles.

[0060] Furthermore, there are multiple first drive components 33 and multiple first clamping components 32, and the multiple first drive components 33 and the multiple first clamping components 32 are spaced apart along the radial direction of the torsion device 3, and the multiple first drive components 33 and the multiple first clamping components 32 are arranged in a one-to-one correspondence. When multiple parts are formed by one injection molding, the multiple first clamping components 32 are arranged in a one-to-one correspondence with the multiple parts. After the multiple first clamping jaw groups 321 clamp the parts correspondingly, the water outlet limiting device 2 limits the injection water outlet, and the multiple first drive components 33 drive the corresponding first clamping components 32 to rotate, and the multiple parts rotate relative to the injection water outlet, so that the multiple parts are separated from the injection water outlet, thereby achieving the technical effect of separating multiple parts and the injection water outlet at the same time.

[0061] Thus, the joint between the part and the injection nozzle is punched by the tool 11 to reduce the thickness of the joint, the part is clamped by the first clamping jaw group 321, and the injection nozzle is limited by the nozzle limiting device 2, and the first driving component 33 drives the first clamping component 32 to rotate, so that the part and the injection nozzle are twisted with each other and the part and the injection nozzle are separated. Compared with the prior art, when separating the part and the injection nozzle, the injection nozzle can be prevented from remaining on the outer surface of the part, thereby improving the product quality of the part.

[0062] Reference Figure 1 , Figure 3 and Figure 5 In some embodiments of the present application, the first driving assembly 33 includes a first connecting member 331, a first driving member 332, a transmission rod 333 and a driving rack 334. Along the second direction of the torsion device 3, the first connecting member 331 is arranged on the front end wall of the mounting frame 31, and the first driving member 332 is arranged on the first connecting member 331. In some specific embodiments, along the first direction of the torsion device 3, the first driving member 332 can be arranged on the right end wall of the first connecting member 331. The first direction of the torsion device 3 can refer to Figure 1 The left and right direction in .

[0063] The driving rack 334 is movably arranged on the first connecting member 331. Specifically, the driving rack 334 is movably arranged on the top wall of the first connecting member 331. The driving rack 334 is connected and cooperated with the first driving member 332. One end of the transmission rod 333 passes through the first connecting member 331 and is connected and cooperated with the first clamping assembly 32, and the other end of the transmission rod 333 is provided with a driving gear 335. That is to say, along the height direction of the torsion device 3, the upper end part of the transmission rod 333 is provided with a driving gear 335, the transmission rod 333 is pivotally connected to the first connecting member 331, and the driving rack 334 is meshed with the driving gear 335. The first driving member 332 is used to drive the driving rack 334 to drive the transmission rod 333 to rotate around the central axis of the transmission rod 333, so that the transmission rod 333 drives the first clamping assembly 32 to rotate.

[0064] Specifically, when the first clamping jaw group 321 clamps the part and the water outlet limiting device 2 limits the water outlet, the first driving member 332 drives the driving rack 334 to move along the first direction of the torsion device 3 away from the first driving member 332, and the driving rack 334 drives the driving gear 335 to rotate, and the driving gear 335 drives the transmission rod 333 to rotate, and the transmission rod 333 drives the first clamping assembly to rotate around the central axis of the transmission rod 333, thereby achieving the technical effect of mutual twisting between the part and the injection water outlet.

[0065] After the separation of the part and the injection nozzle is completed, the first driving member 332 drives the driving rack 334 to move along the first direction of the twisting device 3 close to the first driving member 332, so that the driving rack 334 drives the first clamping assembly 32 to reset.

[0066] Furthermore, the first driving component 33 may also include a limiting rack 336, which is movably arranged on the top wall of the first connecting member 331, and the driving gear 335 is clamped between the driving rack 334 and the limiting rack 336. Along the second direction of the torsion device 3, the limiting rack 336 and the driving rack 334 are arranged opposite to and spaced apart from each other, the limiting rack 336 is meshingly connected with the driving gear 335, and the first connecting member 331 is provided with a limiting guide rail 337. Along the first direction of the twisting device, the left and right ends of the limiting guide rail 337 are both provided with limiting parts, the limiting rack 336 is guided and matched with the limiting guide rail 337, and the limiting rack 336 is limitedly matched with the limiting part.

[0067] Specifically, when the driving rack 334 drives the driving gear 335 to rotate, the driving gear 335 simultaneously drives the limiting rack 336 to move along the limiting guide rail 337. When the first clamping assembly 32 rotates to a preset angle, the limiting rack 336 cooperates with the limiting part, thereby preventing the first driving member 332 from continuously driving the driving rack 334 to move away from the first driving member 332, causing the driving rack 334 and the driving gear 335 to separate, thereby preventing the driving rack 334 from being unable to drive the first clamping assembly 32 to rotate.

[0068] In some specific embodiments, when the part and the injection nozzle are twisted against each other, the limit rack 336 can be limitedly matched with the limit part located at the left end of the limit guide rail 337. When the first clamping assembly 32 is reset, the limit rack 336 can be limitedly matched with the limit part located at the right end of the limit guide rail 337.

[0069] In some specific embodiments, the first driving member 332 may be a cylinder, but the present application is not limited thereto, and the first driving member 332 may also be a hydraulic cylinder or the like.

It should be noted that the transmission rod 333 is connected and matched with the second driving member 322.

[0071] Specifically, when the first jaw group 321 clamps a part, first the second driving member 322 drives the multiple first jaws 3211 to move in the opposite direction to increase the clamping gap 3212 and allow the part to enter the clamping gap 3212, and then the second driving member 322 drives the multiple first jaws 3211 to move toward each other to reduce the clamping gap 3212 and allow the multiple first jaws 3211 to clamp the circumferential edge of the part at the same time, thereby achieving the technical effect of multiple first jaws 3211 clamping parts.

[0072] After the separation of the part and the injection nozzle is completed, the second driving member 322 drives the plurality of first clamping jaws 3211 to move in the opposite direction to release the part.

[0073] In some specific embodiments, the second driving member 322 may be a rotary cylinder or the like.

[0076] In other specific embodiments, a part conveyor belt is arranged under the first clamping assembly 32. After the part and the injection nozzle are separated, the third driving member 34 drives the first clamping assembly 32 to move downward close to the part conveyor belt. When the third driving member 34 drives the connecting plate 35 to move downward to a preset position, the second driving member 322 drives the multiple first clamps 3211 to move in the opposite direction to place the part on the part conveyor belt, thereby preventing the part from falling from the first clamping jaw group 321 to the ground and causing damage to the part, thereby improving the user experience of the part nozzle removal device 100.

Through the guiding cooperation of the first guide structure 311 and the second guide structure 351, the connecting plate 35 can be prevented from deviating from the preset motion trajectory, thereby preventing the third driving member 34 from being unable to drive the first clamping assembly 32 to move above the part conveyor belt, thereby improving the working reliability of the part water outlet removal device 100.

[0079] In some specific embodiments, the third driving member 34 may be a cylinder, but the present application is not limited thereto, and the third driving member 34 may also be a hydraulic cylinder or the like.

[0080] Reference Figure 1 and Figure 4 In some embodiments of the present application, the torsion device 3 may further include a position detection component 36 and a controller. The position detection component 36 is arranged on the mounting frame 31. Specifically, along the first direction of the torsion device 3, the position detection component 36 can be arranged on the left end wall or the right end wall of the mounting frame 31. The position detection component 36 includes a first position detection member 361 and a second position detection member 362. Along the height direction of the torsion device 3, the first position detection member 361 is located above the second position detection member 362. The first position detection member 361 and the second position detection member 362 are both used to detect the position height of the connecting plate 35. The position detection component 36 and the third driving member 34 are both communicatively connected to the controller. The controller is used to control the third driving member 34 to start or stop working according to the detection signal of the position detection component 36.

[0081] Specifically, when the third driving member 34 drives the connecting plate 35 to move downward to the first preset position, the second position detection member 362 is triggered and generates a detection signal. The controller is used to control the third driving member 34 to stop working according to the detection signal of the second position detection member 362, thereby preventing the third driving member 34 from driving the first clamping assembly 32 to continue to move downward, thereby preventing the first clamping assembly 32 from colliding with the parts conveyor belt, and further improving the working reliability of the water outlet removal device.

[0082] When the third driving member 34 drives the connecting plate 35 to move upward to the second preset position, the first position detection member 361 is triggered and generates a detection signal. The controller is used to control the third driving member 34 to stop working according to the detection signal of the first position detection member 361, thereby preventing the third driving member 34 from driving the connecting plate 35 to move continuously upward, preventing the connecting plate 35 from separating from the mounting frame 31, and further improving the working reliability of the water outlet removal device.

[0083] When neither the first position detection member 361 nor the second position detection member 362 is triggered, the controller controls the third driving member 34 to start working. After the part is placed on the part conveyor belt, the third driving member 34 drives the first clamping assembly 32 to move upward away from the part conveyor belt. After the part and the injection nozzle are separated, the third driving member 34 drives the first clamping assembly 32 to move downward toward the part conveyor belt.

[0084] In some specific embodiments, the first position detection member 361 and the second position detection member 362 are both constructed as infrared sensors, but the present application is not limited thereto. The first position detection member 361 and the second position detection member 362 can also be constructed as Hall effect sensors. It should be noted that when the first position detection member 361 and the second position detection member 362 are both constructed as Hall effect sensors, a metal sheet is provided on the side wall of the connecting plate 35 close to the position detection component 36, and the metal sheets are suitable for being arranged opposite to and spaced apart from the first position detection member 361 and the second position detection member 362.

[0085] Reference Figure 3 , Figure 4 and Figure 6 In some embodiments of the present application, the torsion device 3 may further include a fourth driving member 37. Along the second direction of the torsion device 3, the fourth driving member 37 is arranged on the front end wall of the connecting plate 35. The fourth driving member 37 is connected and cooperated with the first driving component 33, and the first driving component 33 is located in front of the fourth driving member 37. Specifically, the first connecting member 331 is connected and cooperated with the fourth driving member 37, and the fourth driving member 37 is used to drive the first driving component 33 to move along the first direction of the part water outlet removal device 100.

[0086] Specifically, a plurality of accommodating grooves can be provided on the part conveyor belt, and the plurality of accommodating grooves are all used to accommodate parts, and the plurality of accommodating grooves are spaced apart along the first direction of the torsion device 3. By connecting and cooperating the first connecting member 331 with the fourth driving member 37, the fourth driving member 37 drives the first connecting member 331 to drive the first clamping assembly 32 to move along the first direction of the torsion device 3. The first clamping jaw group 321 can accurately place the parts on the accommodating groove of the part conveyor belt, thereby preventing the parts from detaching from the part conveyor belt, and preventing the part conveyor belt from being unable to transport the parts to the preset area, thereby improving the working reliability of the part water outlet removal device 100.

[0087] Further, when there are multiple first drive components 33 and multiple first clamping components 32, and there is one fourth drive component, one of the multiple first drive components 33 is connected and matched with the fourth drive component 37. Figure 1 In the illustrated embodiment, there are two first drive assemblies 33 and two first clamping assemblies 32, the two first drive assemblies 33 are arranged opposite to and spaced apart along the first direction of the torsion device 3, and one of the two first drive assemblies 33 is connected to and cooperates with the fourth drive member 37, and the water outlet limiting device 2 is arranged between the two first clamping assemblies 32.

[0088] It is difficult to keep the lengths of parts and injection nozzles formed by injection molding of different molds consistent. The injection nozzle length can refer to the first direction of the twisting device 3. When two parts are formed by one injection molding and the two parts are separated from the injection nozzle, one of the multiple receiving slots is suitable to be opposite to the first clamping assembly 32 that cannot be driven by the fourth driving member 37. That is to say, each time the part conveyor belt completes a part conveying, one of the receiving slots without parts is opposite to the first clamping assembly 32 that cannot be driven by the fourth driving member 37. The fourth driving member 37 drives the corresponding first clamping assembly 32 to move along the first direction of the twisting device 3, so that the corresponding first clamping jaw group 321 can accurately place the part in the corresponding receiving slot. The twisting device 3 can adapt to injection nozzles of different lengths, thereby improving the user experience of the part nozzle removal device 100.

[0089] In some specific embodiments, the fourth driving member 37 may be a cylinder, but the present application is not limited thereto, and the fourth driving member 37 may also be a hydraulic cylinder or the like.

[0090] Reference Figure 7-Figure 9 In some embodiments of the present application, the water outlet limiting device 2 includes a fifth driving member 21 and a second clamping assembly 22, the second clamping assembly 22 includes a sixth driving member 221 and a second jaw group 222, the second jaw group 222 is transmission-connected to the sixth driving member 221, the sixth driving member 221 is used to drive the second jaw group 222 to clamp the injection water outlet, the fifth driving member 21 is connected and cooperated with the sixth driving member 221, the fifth driving member 21 is used to drive the sixth driving member 221 to drive the second jaw group 222 to move close to the injection water outlet, so that the second jaw group 222 limits the injection water outlet.

[0091] Specifically, when the first clamping assembly 32 clamps the part, the fifth driving member 21 drives the sixth driving member 221 to drive the second jaw group 222 to move close to the injection nozzle, and the sixth driving member 221 drives the second jaw group 222 to clamp the injection nozzle, and then the first driving assembly 33 drives the first clamping assembly 32 to rotate to separate the part and the injection nozzle, thereby achieving the technical effect of limiting the injection nozzle, and avoiding the situation where the part drives the injection nozzle to rotate when the first driving assembly 33 drives the first clamping assembly 32 to rotate, resulting in the part and the injection nozzle being unable to be separated.

[0092] After the separation of the part and the injection nozzle is completed, the fifth driving member 21 drives the sixth driving member 221 to drive the second clamping member 222 to move away from the first clamping assembly 32. When the sixth driving member 221 moves to the preset position, the sixth driving member 221 drives the second clamping member 222 to release the injection nozzle, thereby preventing the injection nozzle from falling onto the part conveyor belt.

[0093] Furthermore, the fifth driving member 21 can be arranged on the mounting frame 31. Such an arrangement eliminates the need to additionally arrange a mounting frame 31 to mount the fifth driving member 21 and the second clamping assembly 22, thereby reducing the floor space occupied by the part nozzle removal device 100.

[0094] Further, refer to Figure 1 and Figure 8 The water outlet limiting device 2 can also include an injection water outlet recovery frame and a recovery guide rail 25. The recovery guide rail 25 is arranged on the mounting frame 31. One end of the recovery guide rail 25 is suitable for being arranged opposite to the second clamping jaw group 222, and one end of the recovery guide rail 25 is arranged opposite to the injection water outlet recovery frame. Along the second direction of the torsion device 3 from front to back, the recovery guide rail 25 is inclined downward. The recovery guide rail 25 is used to guide the injection water outlet to the injection water outlet recovery frame. Specifically, after the sixth driving member 221 releases the injection water outlet, the injection water outlet falls on the recovery guide rail 25, and the injection water outlet moves along the recovery guide rail 25 and enters into the injection water outlet recovery frame, thereby achieving the technical effect of recovering the injection water outlet.

[0095] Furthermore, the second jaw group 222 includes a plurality of second jaws 2221, and the plurality of second jaws 2221 are spaced apart along the circumferential direction of the sixth driving member 221, and the plurality of second jaws 2221 are all transmission-connected to the sixth driving member 221, and the sixth driving member 221 is used to drive the plurality of second jaws 2221 to move toward each other to clamp the injection nozzle, and the sixth driving member 221 is used to drive the plurality of second jaws 2221 to move in the opposite direction to release the injection nozzle.

[0096] Furthermore, when there are two first clamping assemblies 32 , the plurality of second clamping jaws 2221 are all located between the two first clamping assemblies 32 .

[0097] In some specific embodiments, the fifth driving member 21 may be a cylinder, and the sixth driving member 221 may be a rotary cylinder, etc., but the present application is not limited thereto, and the fifth driving member 21 may also be a hydraulic cylinder, etc.

[0098] Reference Figure 7-Figure 9 In some embodiments of the present application, the water outlet limiting device 2 may further include a pivot member 23 and a seventh driving member 24. Along the second direction of the torsion device 3, the sixth driving member 221 is pivotally connected to the front end wall of the pivot member 23. The fifth driving member 21 and the seventh driving member 24 are both connected and cooperated with the pivot member 23. Along the height direction of the torsion device 3, the seventh driving member 24 is pivotally connected to the lower end of the sixth driving member 221. The seventh driving member 24 drives the output end of the seventh driving member 24 to extend or shorten, so as to drive the sixth driving member 221 to rotate around the pivot axis between the sixth driving member 221 and the pivot member 23, and adjust the angle of the second jaw group 222.

[0099] Specifically, it is difficult to maintain the consistent height position relationship between parts and injection nozzles formed by different molds. That is to say, when the first jaw group 321 clamps the parts, along the height direction of the torsion device 3, the injection nozzles formed by different molds are difficult to be opposite to the second jaw group 222. The seventh driving member 24 is used to drive the output end of the seventh driving member 24 to extend or shorten, so that the output end of the seventh driving member 24 drives the sixth driving member 221 to rotate, and the sixth driving member 221 drives the second jaw group 222 to rotate around the pivot axis between the sixth driving member 221 and the pivot member 23 to adjust the angle of the second jaw group 222 so that the second jaw group 222 can be opposite to the injection nozzles formed by different molds, thereby improving the use experience of the nozzle removal device.

[0100] In some specific embodiments, the seventh driving member 24 may be a cylinder, but the present application is not limited thereto, and the seventh driving member 24 may also be a hydraulic cylinder or the like.

[0101] Reference Figure 10-12 In some embodiments of the present application, the punching device 1 further includes a support seat 12 and an eighth driving member 13. Along the height direction of the punching device 1, the parts are suitable for being fixed to the upper end wall of the support seat 12, the tool 11 is movably arranged on the upper end wall of the support seat 12, the eighth driving member 13 is arranged on the support seat 12, and the eighth driving member 13 is connected and matched with the tool 11. The eighth driving member 13 is used to drive the tool 11 to move close to the joint, that is, the eighth driving member 13 drives the tool 11 to move along the first direction of the punching device 1. It should be noted that the first direction of the punching device 1 can be the same as the first direction of the twisting device 3, and the height direction of the punching device 1 can be the same as the height direction of the twisting device 3.

[0102] Specifically, after the part is injection molded in the injection mold, the robot arm takes out the part and the injection nozzle from the injection mold and places the part and the injection nozzle on the support seat 12. After the part is placed on the support seat 12, the eighth driving member 13 drives the tool 11 to move close to the joint, so that the tool 11 can punch the joint between the part and the injection nozzle. After the tool 11 completes the punching work, the eighth driving member 13 drives the tool 11 to move away from the joint to reset the tool 11.

[0103] In some specific embodiments, the eighth driving member 13 may be a cylinder, but the present application is not limited thereto. The eighth driving member 13 may also be a hydraulic cylinder or the like.

[0105] In some specific embodiments, the worker may drive the cutter 11 along the second direction of the punching device 1 by hand.

[0106] Further, refer to Figure 12-14 The support seat 12 is provided with a third guide structure 121, and the second connecting member 15 is provided with a fourth guide structure 151. The third guide structure 121 and the fourth guide structure 151 are guided in cooperation with each other. Through the guiding cooperation between the third guide structure 121 and the fourth guide structure 151, the second connecting member 15 can be prevented from deviating from the preset motion trajectory, thereby preventing the eighth driving member 13 from being unable to drive the second connecting member 15 to move the tool 11 close to the joint, thereby improving the working reliability of the part water nozzle removal device 100.

[0107] In some specific embodiments, the eighth driving member 13 may be a cylinder, but the present application is not limited thereto, and the eighth driving member 13 may also be a hydraulic cylinder or the like.

[0108] Reference Fig.10 , Fig.11 and Fig.13 In some embodiments of the present application, the punching device 1 further includes a positioning member 14. The positioning member 14 is installed on the upper end wall of the support seat 12 along the height direction of the punching device 1. The positioning member 14 is suitable for extending into the part to fix and position the part.

[0109] Specifically, after the robot arm takes out the part from the injection mold, the robot arm places the part on the positioning piece 14, and the positioning piece 14 extends into the part, thereby achieving the technical effect of positioning the part through the positioning piece 14.

[0110] Furthermore, a positioning portion 141 is also provided on the upper end wall of the positioning member 14, and a positioning hole is provided on the part, and the positioning portion 141 extends into the positioning hole so that the positioning portion 141 and the positioning hole are positioned and matched, thereby preventing the part from being separated from the positioning member 14, preventing the tool 11 from being unable to punch the joint, and further improving the working reliability of the water outlet removal device.

[0111] Furthermore, there are multiple positioning portions 141, and the multiple positioning portions 141 are spaced apart along the circumferential direction of the positioning member 14. The multiple positioning portions 141 can all extend into a positioning hole, thereby avoiding damage to one of the multiple positioning portions 141, which causes the positioning portion 141 to be unable to be positioned and cooperated with the positioning hole, thereby further improving the working reliability of the water outlet removal device.
