Description

Technical Field

[0001] This utility model relates to the technical field of in-mold riveting devices, and specifically to an in-mold riveting device. Background Technology

[0002] In the air conditioning industry, for fixed sheet metal riveted components, the traditional processing method for riveting hexagonal nuts mainly relies on manual riveting. This manual method is inefficient; high-speed stamping lines produce parts at approximately three times the rate of manual riveting, requiring at least three employees for subsequent riveting processes to prevent parts from piling up at the beginning. The disconnect between the stamping and riveting processes leads to waste in the secondary packaging and logistics of semi-finished parts.

[0003] In-mold riveting technology has gradually been favored by sheet metal processing companies. However, current automated in-mold riveting devices all use gas to push rivets into the mold. Due to the long rivet movement track distance and unstable airflow, this method often results in rivet jamming, requiring frequent line stops and manual intervention to correct the jamming, leading to low production efficiency.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide an in-mold riveting device to solve the technical problem of low in-mold riveting efficiency in related technologies.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: It provides an in-mold riveting device, comprising:

[0007] The feeding module is used to arrange rivets and transport the arranged rivets one by one. The feeding module has an output port to output the rivets one by one.

[0008] The rivet feeding module includes a movable rivet feeding slider and a conveying mechanism driven by the rivet feeding slider. The rivet feeding slider is provided with a positioning component for positioning the rivet feeding slider. The positioning component is openable and closable. The conveying mechanism drives the rivet feeding slider to reciprocate between the output port and the stamping mechanism to convey the rivet to the stamping mechanism for riveting.

[0009] Furthermore, the positioning component includes a limiting pressure block, and there are at least two limiting pressure blocks. The at least two limiting pressure blocks are disposed opposite to each other on the rivet feeding slider. A rivet is accommodated between the at least two limiting pressure blocks. A limiting pressure groove adapted to the shape of the rivet is opened on the side of the limiting pressure block near the rivet feeding slider. The limiting pressure groove abuts against the rivet. The at least two limiting pressure blocks are rotatably disposed in the direction away from the rivet.

[0010] Furthermore, the positioning component includes a stripping block mounted on the nail feeding slider. The stripping block is movably arranged along the height direction of the nail feeding slider. The stripping block has a stripping cavity for accommodating a limiting block. The shape of the stripping cavity is adapted to the shape of the limiting block. The limiting block is rotatably arranged in the stripping cavity. There are at least two stripping blocks, and each of the at least two stripping blocks is respectively arranged in a one-to-one correspondence with at least two limiting blocks.

[0011] Furthermore, the rivet feeding module includes a guide rail that intersects with the output port, and a rivet feeding slider is slidably connected on the guide rail;

[0012] The conveying mechanism includes a first cylinder, the piston rod of the first cylinder extends in the same direction as the guide rail, and the piston rod is connected to the feeding slider.

[0013] Furthermore, the in-mold riveting device includes a first detection component, which is located at the output port. The detection end of the first detection component is correspondingly arranged with the riveting slider, and the first detection component is signal-connected to the conveying mechanism.

[0014] Furthermore, the feeding module includes a material distribution mechanism for conveying the rivets one by one. The material distribution mechanism includes:

[0015] The material distribution track contains a set of rivets, and an output port is provided at one end of the material distribution track near the rivet feeding module.

[0016] A stop component is telescopically mounted on the side wall of the material distribution track. The stop component and the rivet can be abutted against each other. The stop component is located on the side of the material distribution track near the output port.

[0017] A pushing component is provided, which is spaced apart from a stop component. The pushing component is located on the side of the material distribution track away from the output port. The pushing component is movably provided along the extension direction perpendicular to the material distribution track. The pushing component is used to push the rivet so that the rivet abuts against the stop component.

[0018] Furthermore, the pushing component includes a pushing portion for abutting against the rivet, the cross-sectional area of ​​which gradually decreases along the direction approaching the rivet.

[0019] Furthermore, the material distribution mechanism includes a second cylinder, the piston rod of the second cylinder extending perpendicularly to the extending direction of the material distribution track, and the piston rod of the second cylinder being connected to the pushing component.

[0020] Furthermore, the feeding module includes an air blowing nozzle, which is fixedly installed above the material distribution track, with the opening of the air blowing nozzle facing the output port.

[0022] Beneficial effects:

[0023] 1. The feeding module can automatically arrange rivets and transport them one by one in an orderly manner. By setting a positioning component, the rivets are positioned to accurately push them into place and ensure riveting accuracy. When riveting is performed, the positioning component opens and closes to smoothly release the rivet pressing. Then, the conveying mechanism drives the rivet feeding slider to send the rivet to the pressing position of the stamping mechanism for riveting operation. In this embodiment, the rivet feeding module replaces the original air-blowing rivet feeding method, changing the unstable airflow push to a stable and controllable mechanical transport, solving the problem of frequent rivet jamming, improving the line operation efficiency, and solving the technical problem of low in-mold riveting efficiency in related technologies.

[0024] 2. By setting limit blocks and limit grooves that abut against the rivet, the limit grooves can be used to press the rivet's cap or body, thereby limiting the rivet that enters between at least two limit blocks. During the riveting process, the limit blocks hold the rivet in place, preventing it from shifting or falling off the feed slider, ensuring stable riveting and guaranteeing riveting accuracy. When at least two limit blocks rotate away from the rivet, the rivet is released, avoiding interference from the positioning components during riveting. At this point, the stamping mechanism can perform the riveting operation. Attached Figure Description

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0038] According to an embodiment of this utility model, an in-mold riveting device is provided. Please refer to [link / reference]. Figures 1 to 7 ,include:

[0039] The feeding module 1 is used to arrange the rivets 10 and to transport the arranged rivets 10 one by one. The feeding module 1 has an output port 11 for outputting the rivets 10 one by one.

[0040] The rivet feeding module 2 includes a movable rivet feeding slider 21 and a conveying mechanism 22 drivenly connected to the rivet feeding slider 21. The rivet feeding slider 21 is provided with a positioning component for positioning the rivet feeding slider 21. The positioning component is openable and closable. The conveying mechanism 22 drives the rivet feeding slider 21 to reciprocate between the output port 11 and the stamping mechanism to convey the rivet 10 to the stamping mechanism for riveting.

[0041] In this way, the feeding module 1 can automatically arrange the rivets 10 and transport the arranged rivets one by one in an orderly manner. By setting a positioning component, the rivets 10 are positioned to accurately push the rivets into place and ensure the riveting accuracy. When riveting is performed, the positioning component opens and closes to release the rivets for riveting. Then, the conveying mechanism 22 drives the rivet feeding slider 21 to send the rivets to the riveting position at the stamping mechanism for riveting operation. In this embodiment, the rivet feeding module 2 replaces the original air-blowing rivet feeding method, changing the unstable airflow push to a stable and controllable mechanical transport, solving the problem of frequent rivet jamming, improving the line operation efficiency, and solving the technical problem of low in-mold riveting efficiency of in-mold riveting devices in related technologies.

[0042] In some embodiments, the in-mold riveting device includes a vibratory feeder 14, which outputs scattered rivets in a standardized manner and orderly enters the material distribution track 121 to wait for them to be pushed to the riveting position.

[0043] In the in-mold riveting device of this embodiment, see... Figure 5-7 The positioning component includes a limiting pressure block 211, and there are at least two limiting pressure blocks 211. The at least two limiting pressure blocks 211 are arranged opposite to each other on the rivet feeding slider 21. A rivet 10 is accommodated between the at least two limiting pressure blocks 211. A limiting pressure groove 212 adapted to the shape of the rivet 10 is opened on the side of the limiting pressure block 211 near the rivet feeding slider 21. The limiting pressure groove 212 abuts against the rivet 10. The at least two limiting pressure blocks 211 are rotatably arranged in the direction away from the rivet 10.

[0044] Specifically, the limiting groove 212 is formed on the side of the limiting block 211 near the rivet feeding slider 21. The shape of the limiting groove 212 is adapted to the shape of the rivet 10. When the rivet 10 is cylindrical, the limiting groove 212 is a semi-cylindrical groove. When the rivet 10 is of other shapes, the shape of the limiting groove 212 is adapted to the shape of the rivet 10 accordingly.

[0045] The axis of rotation of the limiting pressure block 211 is parallel to the direction of movement of the rivet feeding slider 21. The limiting pressure block 211 can rotate around the axis. When the limiting pressure block 211 rotates, the contact state between the limiting pressure groove 212 and the rivet 10 changes, thereby achieving the clamping or release of the rivet 10.

[0046] Thus, see Figure 6 By setting a limiting pressure block 211, the limiting pressure groove 212 abuts against the rivet 10. The limiting pressure groove 212 can be used to press the cap or body of the rivet 10, thereby limiting the rivet 10 that enters between at least two limiting pressure blocks 211. During the riveting process, the limiting pressure block 211 presses the rivet 10 to prevent it from shifting or falling off the rivet feed slider 21, ensuring stable riveting and guaranteeing riveting accuracy. See also Figure 7 When at least two limiting blocks 211 rotate in a direction away from the rivet 10, the rivet 10 is released, thus avoiding interference between the positioning component and the mold during riveting. At this time, the stamping mechanism can perform the riveting operation.

[0047] In the in-mold riveting device of this embodiment, see... Figure 5-7 The positioning component includes a stripping block 213 mounted on the nail feeding slider 21. The stripping block 213 is movably arranged along the height direction of the nail feeding slider 21. The stripping block 213 has a stripping cavity 214 for accommodating a limiting block 211. The shape of the stripping cavity 214 is adapted to the shape of the limiting block 211. The limiting block 211 is rotatably arranged in the stripping cavity 214. There are at least two stripping blocks 213, and each of the at least two stripping blocks 213 is respectively arranged in a one-to-one correspondence with the at least two limiting blocks 211.

[0048] Specifically, based on the structural characteristics of the production mold, the rivet enters from below the part, and the riveting method adopts a "bottom-up" form. The rivet is inserted into the rivet hole of the part and is riveted under pressure. During the riveting process, the rivet feeding slider 21 needs to remove the rivet from the rivet feeding slider 21 to ensure that the riveting process is smooth and stable.

[0049] Specifically, the stripping chamber 214 is located on the side of the stripping block 213 near the nail feeding slider 21. The shape of the stripping chamber 214 is adapted to the shape of the limiting block 211, so that the limiting block 211 can rotate freely in the stripping chamber 214.

[0050] Preferably, the limiting block 211 has a cylindrical or hemispherical structure, so that the limiting block 211 moves smoothly during rotation and reduces its rotational resistance.

[0051] In some embodiments, see Figure 6-7 An elastic element is provided under the limiting pressure block 211. The elastic element is eccentrically positioned relative to the axis of the limiting pressure block 211. The limiting pressure block 211 and the unloading chamber 214 are eccentrically positioned relative to the center of the unloading pressure block 213. Thus, when the unloading pressure block 213 is pressed, the limiting pressure block 211 is deflected away from the rivet 10 to release the rivet 10.

[0052] In this way, by setting the stripping pressure block 213, during the punch press riveting process, the stripping pressure block 213 is pressed down and moves to drive the limiting pressure block 211 to open, releasing the rivet 10, so that the rivet 10 is riveted and fixed to the part, ensuring the riveting quality.

[0053] Preferably, there are two stripping blocks 213 and two limiting blocks 211. The rivet feeding slider 21 has two mounting slots for accommodating the stripping blocks 213, and a platform for placing the rivets 10 is provided between the two mounting slots.

[0054] In some embodiments, a reset spring is provided below the stripping block 213 so that the stripping block 213 is reset after riveting is completed.

[0055] In the in-mold riveting device of this embodiment, see... Figure 1-2 The rivet feeding module 2 includes a guide rail 23, which intersects with the output port 11, and a rivet feeding slider 21 is slidably connected on the guide rail 23.

[0056] The conveying mechanism 22 includes a first cylinder 221, the piston rod of which extends in the same direction as the guide rail 23, and the piston rod is connected to the feeding slider 21. This arrangement allows the first cylinder 221 to drive the feeding slider 21 in the direction of the guide rail 23.

[0057] Preferably, the extension direction of the guide rail 23 is perpendicular to the extension direction of the output port 11, thereby changing the conveying direction of the rivet 10 and improving the overall width and footprint of the equipment.

[0058] Specifically, the guide rail 23 is a linear guide rail, and the extension direction of the guide rail 23 is perpendicular to the extension direction of the output port 11. The guide rail 23 is fixedly laid on the frame and the mold 3, and a nail feeding slider 21 is provided on the guide rail 23. The nail feeding slider 21 can move back and forth along the extension direction of the guide rail 23.

[0059] Specifically, the guide rail 23 is laid between the part material strip guide blocks 6 on the mold 3 according to the structural characteristics of the part.

[0060] Specifically, the first cylinder 221 is a pneumatic cylinder, which is fixed on the frame. The piston rod of the first cylinder 221 is connected to the nail feeding slider 21. The extension direction of the piston rod of the first cylinder 221 is consistent with the extension direction of the guide rail 23. The extension and retraction of the piston rod of the first cylinder 221 can drive the nail feeding slider 21 to reciprocate along the extension direction of the guide rail 23.

[0061] In the in-mold riveting device of this embodiment, see... Figure 1 The in-mold riveting device includes a first detection component 4, which is located at the output port 11. The detection end of the first detection component 4 is correspondingly set with the riveting slider 21, and the first detection component 4 is signal connected to the conveying mechanism 22.

[0062] Specifically, the detection end of the first detection component 4 is positioned facing the positioning component on the rivet feeding slider 21. When the rivet 10 reaches the positioning component, the first detection component 4 detects the presence of the rivet 10 and sends a signal to the conveying mechanism 22. After receiving the signal, the conveying mechanism 22 drives the rivet feeding slider 21 to move, taking the rivet 10 from the output port 11 and conveying it to the stamping mechanism for riveting.

[0063] In some embodiments, the detection sensor of the first detection component 4 may be a non-contact sensor such as an infrared sensor.

[0064] In the in-mold riveting device of this embodiment, see... Figure 1-3 The feeding module 1 includes a material distribution mechanism 12 for conveying the rivets 10 one by one. The material distribution mechanism 12 includes:

[0065] The material distribution track 121 contains arranged rivets 10, and an output port 11 is provided at one end of the material distribution track 121 near the rivet feeding module 2.

[0066] Stop component 122 is telescopically mounted on the side wall of the material distribution track 121. The stop component 122 is abutting against the rivet 10. The stop component 122 is located on the side of the material distribution track 121 near the output port 11.

[0067] A pushing component 123 is provided at a distance from a stop component 122. The pushing component 123 is located on the side of the material distribution track 121 away from the output port 11. The pushing component 123 is movably provided along the extension direction perpendicular to the material distribution track 121. The pushing component 123 is used to push the rivet 10 so that the rivet 10 abuts against the stop component 122.

[0068] In some embodiments, the stop member 122 is a limiting ball.

[0069] Specifically, the bottom of the material distribution track 121 is flat, the two sides of the material distribution track 121 are side walls, the inlet of the material distribution track 121 is connected to the vibrating plate 14, and the end of the material distribution track 121 is provided with an output port 11. The position of the output port 11 corresponds to the position of the rivet feeding slider 21, so that the rivet feeding slider 21 can take the rivet 10 from the output port 11. The bottom of the material distribution track 121 is used to support the rivet 10, and the side walls of the material distribution track 121 are used to restrict the lateral movement of the rivet 10.

[0070] The stop component 122 is a retractable stop block, which is retractably mounted on the side wall of the dispensing track 121. The stop component 122 can switch between an extended state and a retracted state. When the stop component 122 is in the extended state, it extends into the dispensing track 121 and abuts against the rivet 10, preventing the rivet 10 from moving towards the output port 11, thus keeping the rivet 10 ready to be pushed. When the stop component 122 is in the retracted state, it retracts into the side wall of the dispensing track 121 and no longer obstructs the movement of the rivet 10.

[0071] The pushing component 123 is a movable pusher block, which is movably arranged along the extension direction perpendicular to the material distribution track 121. The pushing component 123 can switch between an extended state and a retracted state. When the pushing component 123 is in the extended state, it extends into the material distribution track 121, pushing the rivet 10 towards the output port 11, causing the rivet 10 to abut against the stop component 122, pushing the stop component 122 back into the side wall of the material distribution track 121, no longer blocking the movement of the rivet 10, and pushing the rivet 10 forward one position to achieve the feeding of rivets one by one. When the pushing component 123 is in the retracted state, it retracts to the outside of the side wall of the material distribution track 121 and no longer pushes the rivet 10.

[0072] By setting up a material distribution track 121, after the rivet enters the material distribution track 121, the material distribution track 121 is perpendicular to the riveting direction. According to the size and structural characteristics of the rivet, the material distribution track 121 and the rivet are reserved with a gap of about 0.15mm on both sides to ensure stable rivet feeding, no jamming, and no deviation. A stop component 122 is set on one side of the material distribution track 121 to restrict the rivet from moving forward. An advance insert push rod is set at the rear end as a pushing component 123, which can provide a sufficiently large force to compress the stop component 122 by pushing and squeezing the rivet, so that the rivet can advance one position.

[0073] In the in-mold riveting device of this embodiment, see... Figure 3 The pushing component 123 includes a pushing part 1231 for abutting against the rivet 10, and the cross-sectional area of ​​the pushing part 1231 gradually decreases along the direction close to the rivet 10.

[0074] Specifically, the pushing part 1231 is a wedge-shaped block, and the cross-sectional area of ​​the pushing part 1231 gradually decreases along the direction close to the rivet 10, so that when the pushing part 1231 pushes the rivet 10, it can make more stable contact with the rivet 10, reduce the impact force, prevent the rivet 10 from jumping or flipping, and allow the pushing part 1231 to gradually insert between two adjacent rivets 10, thus ensuring the pushing efficiency of the pushing part 1231.

[0075] In the in-mold riveting device of this embodiment, see... Figure 2 The material distribution mechanism 12 includes a second cylinder 124, the piston rod of the second cylinder 124 extends perpendicularly to the extension direction of the material distribution track 121, and the piston rod of the second cylinder 124 is connected to the pushing component 123.

[0076] Specifically, the second cylinder 124 is a pneumatic cylinder, which is fixed on the frame. The piston rod of the second cylinder 124 is connected to the pushing component 123. The extension direction of the piston rod of the second cylinder 124 is perpendicular to the extension direction of the material distribution track 121. The second cylinder 124 can drive the pushing component 123 to reciprocate along the extension direction perpendicular to the material distribution track 121.

[0077] In the in-mold riveting device of this embodiment, see... Figure 1-3 The feeding module 1 includes an air blowing nozzle 13, which is fixedly installed above the material distribution track 121, with the opening of the air blowing nozzle 13 facing the output port 11.

[0078] Specifically, one end of the air nozzle 13 is connected to an air source, and the other end is an opening facing the output port 11. The air nozzle 13 can blow air onto the rivet 10, causing the rivet 10 to move within the material distribution track 121, thereby achieving automatic feeding of the rivet 10. The airflow direction of the air nozzle 13 is consistent with the extension direction of the material distribution track 121, and the airflow can push the rivet 10 towards the output port 11.

[0079] Specifically, when the rivet passes the stop component 122, it is pushed forward by the air nozzle 13 to the space between the two limit pressure blocks 211 and automatically enters the limit pressure groove 212.

[0080] By setting an air nozzle 13, the power compensation for the forward movement of the front rivet after passing the stop component 122 is provided to solve the problem of the rivet stopping. When the rivet feeding slider 21 is in place, the solenoid valve controls the air jet to blow the rivet into the rivet feeding slider 21, effectively preventing the equipment from being damaged by accidental air blowing during non-feeding periods.

[0081] A stop component 122 is installed inside the material distribution track 121 to restrict the rivets from moving forward. The second cylinder 124 pushes the pushing component 123 to advance the arranged rivets forward by one rivet position. The stop component 122 is compressed by the spring, causing the rivets to advance one position. The foremost rivet passes the stop component 122, and then the air nozzle 13 blows the rivet forward to the rivet feeding slider 21. Then, the first cylinder 221 drives the rivet feeding slider 21 to deliver the rivet to the riveting position.

[0082] In the in-mold riveting device of this embodiment, see... Figure 1 The in-mold riveting device includes a second detection component 5, which is located at the stamping mechanism. The detection end of the second detection component 5 is correspondingly set with the riveting slider 21, and the second detection component 5 is signal connected to the stamping mechanism.

[0083] Specifically, the detection end of the second detection component 5 is positioned facing the rivet feed slider 21. When the rivet feed slider 21 reaches the stamping mechanism, the second detection component 5 detects the presence of the rivet feed slider 21 and sends a signal to the stamping mechanism. After receiving the signal, the stamping mechanism starts working and rivets the rivet 10.

[0084] Specifically, to enhance the applicability of the device and meet the flexible adjustment of different rivet hole positions of parts, a second detection component 5 is set at the end of the guide rail 23 to ensure that the rivet is accurately delivered. The second detection component 5 of different sizes can be replaced according to the rivet hole position to meet the riveting requirements of various parts.

[0085] Specifically, depending on the location of the riveting hole on the part, the riveting push distance can be set according to production needs. The second detection component 5 can be made in different sizes as required and installed to meet the riveting production needs of various parts and improve the versatility and flexibility of the in-mold riveting device.

[0086] In some embodiments, the detection sensor of the second detection component 5 is a contact sensor, such as a magnetic sensor.

[0087] In some embodiments, the in-mold riveting device is based on minor mold modifications and modular combination principles. By reserving independent step positions through continuous mold opening, the in-mold riveting device with the installation push rod type rivet feeding device of this application is installed in the mold. While ensuring that the quality of the parts meets the process requirements, the in-mold riveting function is integrated. The employee only needs to pour the rivets into the vibratory plate 14, adjust the stamping feeding and other preparations, and then start the equipment to start production.

[0088] In some embodiments, the working process of the in-mold riveting device is as follows: The rivets 10 are poured into the vibratory feeder 14, which neatly arranges the scattered rivets and feeds them into the feeding track 121. After the rivets enter the feeding track 121, their front ends are blocked by the stop component 122, stopping their forward movement. The second cylinder 124 pushes the pushing component 123 to push the rivets forward one position. After the front end of the rivet passes the stop component 122, it is pushed forward by the air nozzle 13 to the rivet feeding slider 21. After the first detection component 4 detects that the rivet is in place, the first cylinder 221 pushes the rivet 10 to the riveting position. The stamping mechanism receives the signal that the rivet has reached the riveting position, performs the stamping action, completes the riveting, and the rivet feeding slider 21 retracts to receive the next rivet, thus repeating the operation.

[0089] In the in-mold riveting device of this embodiment, the feeding module 1 realizes the orderly and sequential delivery of rivets; it realizes the transportation of rivets by means of cylinder push, and iterates the original air blowing rivet delivery method, changing the unstable airflow push to a stable and controllable mechanical transportation, solving the problem of frequent rivet jamming; the positioning component accurately pushes the rivets into place and smoothly releases the rivet pressing, which improves the efficiency of the production line, reduces the labor intensity of employees, and improves the morale of the workers.

[0090] In the in-mold riveting device of this embodiment, based on the working and structural characteristics of the progressive die, only minor modifications are needed to the original die to install a rivet feeding device, so as to realize the continuous in-mold production of the front-end stamping and forming process and the back-end rivet nut process, which effectively improves production efficiency and reduces labor input costs.
