Description

Technical Field

[0001] This application relates to the field of production equipment for seat belt buckle sheaths, and in particular to a runner waste trimming device. Background Art

[0002] A seat belt is the only guarantee for a driver's driving safety and is an active safety measure. It can save lives at critical moments. A vehicle seat belt generally includes a buckle fixed on one side of the seat, a webbing, and a tongue provided on the webbing. Usually, the tongue is inserted into the socket of the buckle to fix the webbing. However, the socket on the buckle of the existing seat belt is generally relatively large, and it is easy for sundries to fall into it, causing damage to the buckle, and even causing injuries to passengers in some special cases. Usually, a seat belt buckle sheath is sleeved on the buckle, and the small holes of the sheath are used to prevent impurities from falling into the inside of the buckle. The seat belt buckle sheath body is usually produced by injection molding.

[0003] Refer to the attached Figure 1 , the injection molded part 1 after injection molding includes a sheath body 2 and a runner waste 3. There are four sheath bodies 2, and the runner waste 3 is connected to the four sheath bodies 2.

[0004] In view of the above related technologies, for the injection molded parts after injection molding, it is usually necessary to manually trim the runner waste to obtain the sheath body, which consumes a large amount of labor costs. Utility Model Content

[0005] In order to reduce the labor cost consumed in the process of trimming the runner waste, this application provides a runner waste trimming device.

[0006] A runner waste trimming device provided by this application adopts the following technical solutions:

[0007] A runner waste trimming device includes a frame, a transport member, and a suction assembly. The transport member is used to drive the injection molded part to be transported horizontally. The suction assembly is used to suck the injection molded part. The suction assembly is connected to the frame through a moving assembly. The frame is provided with a trimming member for trimming the runner waste. The trimming member is arranged above the transport member. The moving assembly is used to drive the suction assembly to move along the transport direction of the transport member and pass through the trimming member. The moving assembly is also used to drive the suction assembly to move vertically.

[0008] By adopting the above technical solution, after injection molding is completed, the injection molded part is placed on the transport piece, and the transport piece drives the injection molded part to move. When the injection molded part approaches the suction component, the moving component drives the suction component to move downward in the vertical direction, so that the suction component approaches the injection molded part. After the suction component sucks the injection molded part, the moving component drives the suction component and the injection molded part to move upward in the vertical direction, so that the injection molded part is away from the transport piece, and the moving component drives the suction component and the injection molded part to move along the transport direction of the transport piece, and the injection molded part passes through the cutting piece. When the injection molded part approaches the cutting piece, the cutting piece cuts the runner waste, so that the runner waste is separated from the sheath body. After cutting is completed, the moving component drives the sheath body away from the cutting piece and makes the sheath body approach the transport piece. When the sheath body approaches the transport piece, the suction component releases the sheath body, so that the sheath body falls onto the transport piece, and the transport piece drives the sheath body to discharge, so as to cut the runner waste, thereby reducing the cost of manual trimming.

[0009] Optionally, the moving component is arranged directly above the cutting piece. The frame is provided with a moving groove, and the length direction of the moving groove is the same as the transport direction of the transport piece. The moving component includes a lead screw, a slider, a first motor, and a first cylinder. The length direction of the lead screw is the same as the transport direction of the transport piece. The lead screw is rotatably connected in the moving groove. The slider is threadedly sleeved on the lead screw and slidably connected in the moving groove along the length direction of the lead screw. The first motor is connected to the frame, and the output shaft of the first motor is connected to one end of the lead screw. The first cylinder is connected to the bottom of the slider, and the piston rod of the first cylinder extends in the vertical direction. The piston rod of the first cylinder is connected to the suction component.

[0010] By adopting the above technical solution, the first motor drives the lead screw to rotate, thereby driving the slider to move along the transport direction of the transport piece. The suction component and the first cylinder move along the transport direction of the transport piece, thereby driving the injection molded part to pass through the cutting piece, and the first cylinder drives the suction component and the injection molded part to move in the vertical direction, thereby driving the injection molded part to approach or move away from the conveyor belt.

[0011] Optionally, the piston rod of the first cylinder is connected with a mounting plate. The suction component includes a suction cup and an air extraction pump. There are four suction cups, and the suction cups correspond to the sheath body one by one. The suction cups are used to connect with the sheath body. The suction cups are connected to the bottom of the mounting plate. The suction cups are used to suck the sheath body. The suction cups are communicated with a suction pipe, and the other end of the suction pipe passes through the mounting plate and is communicated with the air extraction pump. The air extraction pump is connected to the mounting plate.

[0012] By adopting the above technical solution, when taking the injection molded part, the first air cylinder drives the mounting plate to move downward in the vertical direction, so that the suction cup approaches and contacts the top of the sheath body. When the suction cup contacts the top of the sheath body, the air extraction pump extracts air from the suction cup, creating a negative pressure inside the suction cup, and the sheath body is adsorbed onto the suction cup, facilitating the taking of the injection molded part. After cutting is completed, the first air cylinder drives the suction component and the injection molded part closer to the transport component, and the air extraction pump blows air into the suction cup, facilitating the separation of the sheath body from the suction cup.

[0013] Optionally, the frame is connected with a collection box, the top of the collection box is open, the collection box is arranged directly below the cut piece, and the collection box is used for collecting runner waste.

[0014] By adopting the above technical solution, after cutting is completed, the runner waste falls into the collection box, facilitating the collection of the runner waste and minimizing the situation where the runner waste falls onto the transport component and exits with the sheath body.

[0015] Optionally, the transport component is a conveyor belt. The frame is connected with a baffle, the baffle is arranged on one side of the collection box close to the feed end of the conveyor belt, the length direction of the baffle is consistent with the width direction of the conveyor belt, the bottom of the baffle contacts the top of the conveyor belt, and the frame is connected with a deviation rectification component. The deviation rectification component is used to adjust the position of the injection molded part on the surface of the conveyor belt and drive the suction cup to align with the sheath body.

[0016] By adopting the above technical solution, the injection molded part after injection molding is placed on the top of the conveyor belt, and the conveyor belt drives the injection molded part to move along the length direction of the conveyor belt. When the injection molded part moves and approaches the baffle, the injection molded part is blocked by the baffle, causing the injection molded part to stay on one side of the baffle close to the feed end of the conveyor belt. At the same time, the deviation rectification component adjusts the position of the injection molded part on the top of the conveyor belt, facilitating the suction of the injection molded part by the suction component and minimizing the situation where the position of the suction cup does not correspond to the position of the sheath body, thereby affecting the cutting position of the cut piece.

[0017] Optionally, the deviation rectification component includes two deviation rectification plates and a second air cylinder. The length direction of the deviation rectification plates is consistent with the length direction of the conveyor belt. The two deviation rectification plates are arranged at intervals in the width direction of the conveyor belt. There is a gap for placing the injection molded part between the two deviation rectification plates. The second air cylinder corresponds to the deviation rectification plates one by one. The second air cylinder is connected to the frame, and the length direction of the second air cylinder is consistent with the width direction of the conveyor belt. The two second air cylinders are arranged at intervals in the width direction of the conveyor belt. The deviation rectification plates are connected to the piston rods of the second air cylinders. The two deviation rectification plates move in the width direction of the conveyor belt and approach or move away from each other, and the deviation rectification plates are used to contact the injection molded part.

[0018] By adopting the above technical solution, when the injection molded part stays on one side of the baffle near the feeding end of the conveyor belt, the second cylinder drives the deviation rectifying plate to move along the width direction of the conveyor belt, and makes the two deviation rectifying plates approach each other. The deviation rectifying plate pushes the injection molded part to move to the middle of the conveyor belt, so that when the suction component sucks the injection molded part, the suction cups and the sheath body correspond one by one, and the situation that the suction is inconvenient due to the non - correspondence between the positions of the suction cups and the sheath body is avoided as much as possible.

[0019] Optionally, the frame is connected with a support rod. The length direction of the support rod is consistent with the width direction of the conveyor belt. The support rod is arranged directly above the collection box. Two moving sleeves are sleeved on the support rod in a sliding manner. The two moving sleeves are arranged at intervals in sequence along the length direction of the support rod. The moving sleeve is slidably connected to the support rod along the length direction of the support rod. There are two cutting members, and the cutting members correspond to the moving sleeves one by one. The cutting member is connected to the moving sleeve. The moving sleeve is connected with a driving component, and the driving component is used to drive the moving sleeve to be slidably connected to the support rod along the length direction of the support rod.

[0020] By adopting the above technical solution, when the moving component drives the injection molded part to move directly above the cutting member, the driving component drives the two moving sleeves to be slidably connected to the support rod along the length direction of the support rod, so as to adjust the distance between the two cutting members, which is convenient for the cutting member to cut the runner waste, and further reduces the situation that the runner waste is not cut clean due to the deviation of the position of the injection molded part.

[0021] Optionally, guide rails are arranged on both sides of the support rod along the length direction of the conveyor belt. The length direction of the guide rail is consistent with the length direction of the support rod. The driving component includes rollers and a second motor. There are two rollers. The rollers are rotatably connected in the moving sleeve. The two rollers are respectively arranged on the inner walls of the two sides of the moving sleeve along the length direction of the conveyor belt. The second motor is connected to the outer wall of the moving sleeve. The output shaft of the second motor is connected to the roller. The roller is in rolling connection with the guide rail.

[0022] By adopting the above technical solution, the second motor drives the roller to rotate, so that the roller is in rolling connection with the guide rail, and the moving sleeve moves along the length direction of the support rod, so as to change the distance between the two cutting members.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. After the injection molding is completed, the injection molded part is placed on the transport part, and the transport part drives the injection molded part to move. When the injection molded part is close to the suction component, the moving component drives the suction component to move downward in the vertical direction, so that the suction component is close to the injection molded part. After the suction component absorbs the injection molded part, the moving component drives the suction component and the injection molded part to move upward in the vertical direction, so that the injection molded part is away from the transport part, and the moving component drives the suction component and the injection molded part to move along the transport direction of the transport part, and the injection molded part passes through the cutting part. When the injection molded part is close to the cutting part, the cutting part cuts the runner waste so that the runner waste is separated from the sheath body. After the cutting is completed, the moving component drives the sheath body away from the cutting part and makes the sheath body close to the transport part. When the sheath body is close to the transport part, the suction component releases the sheath body, so that the sheath body falls onto the transport part, and the transport part drives the sheath body to discharge the material, so as to cut the runner waste, thereby reducing the cost of manual trimming;

[0025] 2. The first motor drives the screw rod to rotate, thereby driving the slider to move along the transport direction of the transport part, and the suction component and the first cylinder move along the transport direction of the transport part, thereby driving the injection molded part to pass through the cutting part, and the first cylinder drives the suction component and the injection molded part to move along the vertical direction, thereby driving the injection molded part to approach or move away from the conveyor belt;

[0026] 3. When the injection molded part is stranded on the side of the baffle plate close to the feeding end of the conveyor belt, the second cylinder drives the correcting plate to move along the width direction of the conveyor belt, and makes the two correcting plates approach each other. The correcting plate pushes the injection molded part to the middle of the conveyor belt, so that when the suction component sucks the injection molded part, the suction cup corresponds to the sleeve body one by one, and the situation that the suction inconvenience caused by the mismatch between the position of the suction cup and the position of the sleeve body is avoided as much as possible.

After sucking the injection molded part 1, the first cylinder 440 drives the injection molded part 1 to move upward along the vertical direction, so that the injection molded part 1 is far away from the conveyor belt 500. The first motor 430 drives the lead screw 410 to rotate, so that the slider 420 moves along the length direction of the conveyor belt 500, thereby driving the injection molded part 1 to approach the cutting part, which is convenient for the cutting part to cut the runner waste 3.

[0041] Referring to Figure 4 and Figure 5 , the suction assembly 200 includes an air extraction pump 210 and four suction cups 220. The suction cups 220 are connected to the bottom of the mounting plate 441. The tops of the suction cups 220 are all communicated with an air extraction pipe 221. The bottom end of the air extraction pipe 221 is communicated with the suction cup 220. The top end of the air extraction pipe 221 passes through the mounting plate 441 along the vertical direction.

[0042] When sucking the injection molded part 1, the air extraction pump 210 extracts air from the suction cups 220, so that a negative pressure is formed in the suction cups 220, so that the injection molded part 1 is adsorbed on the suction cups 220, which is convenient for the moving assembly 400 to drive the injection molded part 1 to move.

[0045] When the injection molded part 1 moves to one side of the baffle 120 following the conveyor belt 500, the second cylinders 610 drive the deviation rectifying plates 620 to move along the width direction of the conveyor belt 500, so that the two deviation rectifying plates 620 approach each other.

[0047] Referring to Figure 2 and Figure 6, the cutting piece is provided for the pneumatic scissors 300, and there are two pneumatic scissors 300. The frame 100 is connected with a support rod 140. The length direction of the support rod 140 is consistent with the width direction of the conveyor belt 500. The support rod 140 is arranged directly above the collection box 130 and in the middle of the collection box 130. Two moving sleeves 150 are sleeved on the support rod 140 in a sliding manner. The two moving sleeves 150 are sequentially and spaced apart along the length direction of the support rod 140, and the moving sleeve 150 is slidably connected to the support rod 140 along the length direction of the support rod 140. The pneumatic scissors 300 correspond to the moving sleeves 150 one by one, and one pneumatic scissors 300 is connected to the top of one moving sleeve 150.

[0048] Refer to Figure 2 and Figure 6 , guide rails 141 are arranged on both sides of the support rod 140 along the length direction of the conveyor belt 500. The length direction of the guide rails 141 is consistent with the length direction of the support rod 140. The moving sleeve 150 is connected with a driving assembly 700, and the driving assembly 700 is used to drive the moving sleeve 150 to be slidably connected to the support rod 140 along the length direction of the support rod 140. The driving assembly 700 includes rollers 710 and a second motor 720. There are two rollers 710. The rollers 710 are rotatably connected inside the moving sleeve 150. The two rollers 710 are respectively arranged on the inner walls of both sides of the moving sleeve 150 along the length direction of the conveyor belt 500.

The central axis of the roller 710 is collinear with the central axis of the output shaft of the second motor 720.

[0049] When the moving assembly 400 drives the injection molded part 1 to move directly above the pneumatic scissors 300, the first cylinder 440 drives the injection molded part 1 to move downward in the vertical direction, so that the runner waste 3 is embedded in the shear opening of the pneumatic scissors 300. The second motor 720 drives the roller 710 to rotate, thereby driving the moving sleeve 150 and the pneumatic scissors 300 to move, so that the pneumatic scissors 300 can adjust the positions of the two pneumatic scissors 300 according to the length of the runner waste 3, which is convenient for the pneumatic scissors 300 to cut the runner waste 3. The runner waste 3 falls into the collection box 130, which is convenient for the collection of the runner waste 3.

[0050] The implementation principle of a runner waste trimming device according to an embodiment of the present application is as follows: After injection molding is completed, the injection molded part 1 is placed on the top of the conveyor belt 500. The conveyor belt 500 drives the injection molded part 1 to move and approach the baffle 120. Due to the blocking effect of the baffle 120, the injection molded part 1 stays on the side of the baffle 120 close to the feeding end of the conveyor belt 500. The first cylinder 440 drives the mounting plate 441 and the suction assembly 200 to move downward in the vertical direction, so that the suction cup 220 approaches the injection molded part 1 and makes the suction cup 220 correspond to the sheath body 2 one by one. When the suction cup 220 contacts the sheath body 2, the air pump 210 pumps air out of the suction cup 220, so that a negative pressure is formed in the suction cup 220, and the suction cup 220 adsorbs the sheath body 2. The first cylinder 440 drives the mounting plate 441 and the suction cup 220 to move upward in the vertical direction, thereby driving the injection molded part 1 away from the conveyor belt 500.

[0051] The first motor 430 drives the lead screw 410 to rotate, thereby making the slider 420 slide in the moving groove 110 along the length direction of the conveyor belt 500 and driving the first cylinder 440 and the injection molded part 1 to move. When the injection molded part 1 moves directly above the pneumatic scissors 300, the first cylinder 440 drives the injection molded part 1 to move downward in the vertical direction, so that the runner waste 3 is inserted into the cutting edge of the pneumatic scissors 300. The second motor 720 drives the roller 710 to rotate, thereby making the moving sleeve 150 and the pneumatic scissors 300 move, which is convenient for the pneumatic scissors 300 to trim the runner waste 3. The trimmed runner waste 3 falls into the collection box 130.

[0052] The moving assembly 400 drives the sheath body 2 away from the pneumatic scissors 300 and close to the conveyor belt 500. When the sheath body 2 approaches the conveyor belt 500, the air pump 210 supplies air into the suction cup 220, so that the sheath body 2 moves away from the suction cup 220, and the sheath body 2 falls onto the top of the conveyor belt 500. The conveyor belt 500 drives the sheath body 2 to be transported and discharged. In this way, the injection molded part 1 is trimmed, thereby reducing the labor cost during the trimming of the injection molded part 1.

[0053] The above are all the preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
