Description

Technical Field

[0001] This application relates to the field of lock tongue plastic coating production technology, and in particular to a lock tongue plastic coating production line. Background Technology

[0002] As a key component at the end of the seatbelt, the locking tongue's safety and durability directly affect the overall protective effect. Under extreme conditions such as car collisions and emergency braking, the locking tongue must withstand impact forces of up to several tons, and its structural strength and fatigue resistance are directly related to the safety of occupants.

[0003] Lock tongue coating production line is the core equipment for achieving large-scale production. It completes multiple processes through automation to ensure that the coating quality of each lock tongue is stable and reliable. Lock tongue coating production line has the advantages of high production efficiency, stable product quality, and sustainable production.

[0004] In existing lock tongue coating production lines, the finished lock tongues are usually transported to a designated workstation via conveyor belt, and then manually packed into blister boxes one by one. However, this manual packing method is inefficient, easily leads to lock tongue accumulation, affects subsequent processes, and requires workers to frequently bend over and grab, resulting in a large workload. Summary of the Invention

[0005] The purpose of this application is to solve the problem mentioned in the background art that requires manual insertion of the manufactured lock tongue into the blister box, which results in low boxing efficiency and a large workload. This application provides a lock tongue plastic coating production line.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A latch encapsulation production line includes a first base, an injection molding unit for injection molding the latch is mounted on the upper end of the first base, a second base is disposed on the side of the first base, a feeding unit for feeding materials and a heating unit for heating the latch are mounted on the upper end of the second base, a third base is disposed on the side of the second base away from the first base, a detection unit for detecting the latch is mounted on the upper end of the third base, a material transfer unit for moving the latch is disposed at the end of the first base, a controller is fixed to the end of the first base away from the material transfer unit, and a support frame is disposed on the side of the third base away from the second base, with a support fixed to the lower end of the support frame. The support frame has a conveyor belt installed inside. The controller is electrically connected to the injection molding unit, feeding unit, heating unit, detection unit, material transfer unit, and conveyor belt. The support frame is equipped with a receiving structure for storing finished locking tongues. The receiving structure includes a mounting frame fixed to the support frame. Multiple positioning strips are fixed on the mounting frame, and blister boxes are placed between the multiple positioning strips. A guide frame is fixed on the mounting frame. One end of the guide frame is closed, and the other end is open. The open end of the guide frame extends into the mounting frame. The mounting frame is equipped with a clamping component and a pushing component. The support frame is equipped with a positioning component.

[0007] By adopting the above technical solution, the production line operates as follows: First, the loading unit is filled with lock tongue parts. Then, the loading unit uses vibration to orderly transport the parts to the heating unit. The multi-axis robotic arm of the transfer unit extends into the heating unit, removes the heated parts, and precisely embeds them into the molding die of the injection molding unit. The controller starts the injection molding unit, completing the plastic coating molding according to preset parameters. After molding, the die automatically demolds, and the robotic arm extends into the die again to remove the molded lock tongue. The transfer unit then transports the molded lock tongue to the inspection unit. The inspection unit inspects each lock tongue individually, checking for missing materials, burrs, and whether the dimensions are up to standard. The inspection data is transmitted to the controller in real time. Qualified lock tongues are sent to the receiving structure, while unqualified lock tongues fall into the recycling box in the inspection unit, achieving precise diversion. Finally, the receiving structure collects the qualified lock tongues and transports them with a conveyor belt. By repeating the above operations, the processing, inspection, and packaging of lock tongues can be achieved.

[0008] Furthermore, the clamping assembly includes two first telescopic cylinders fixed on the mounting frame. The two first telescopic cylinders are symmetrically arranged. The first telescopic cylinders are electrically connected to the controller. The telescopic end of the first telescopic cylinder is fixed with a clamping plate.

[0009] By adopting the above technical solution, the first telescopic cylinder, together with the clamping plate, can clamp and restrict the stacked blister boxes, making it easier for the subsequent pushing component to push the blister boxes out.

[0010] Furthermore, the pushing assembly includes a multi-stage telescopic cylinder fixed on the mounting frame. The multi-stage telescopic cylinder is electrically connected to the controller. A pushing plate is fixed to the telescopic end of the multi-stage telescopic cylinder. The end of the pushing plate away from the multi-stage telescopic cylinder is attached to the bottommost blister box.

[0011] By adopting the above technical solution, the multi-stage telescopic cylinder extends to drive the pusher plate to move, and in conjunction with the conveyor belt, it can send the bottom blister box out of the mounting frame, so that the locking tongue can be installed later.

[0012] Furthermore, the positioning assembly includes two second telescopic cylinders fixed on the support frame. The two second telescopic cylinders are symmetrically arranged and electrically connected to the controller. A first positioning block is fixed to the telescopic end of each second telescopic cylinder. The first positioning block is located above the conveyor belt, and the side of the first positioning block away from the second telescopic cylinder is used to abut against the end of the blister pack.

[0013] By adopting the above technical solution, the second telescopic cylinder, in conjunction with the first positioning block, can position both ends of the blister box, preventing the blister box from shifting position when the finished product lock tongue is placed.

[0014] Furthermore, the positioning assembly also includes a third telescopic cylinder fixed to the support frame. A second positioning block is fixed to the telescopic end of the third telescopic cylinder, and the third telescopic cylinder is electrically connected to the controller. The second positioning block is located above the conveyor belt and has a right-angle positioning groove for abutting against the corner of the blister pack.

[0015] By adopting the above technical solution, the third telescopic cylinder, in conjunction with the second positioning block, can position the corners of the blister box, thereby improving the positioning effect.

[0016] Furthermore, a first fiber optic sensor is fixed on the support frame, and the first fiber optic sensor is electrically connected to the controller. The first fiber optic sensor is located on one side of the second telescopic cylinder and corresponds to the position of the third telescopic cylinder.

[0017] By adopting the above technical solution, when the blister box moves to the position of the first fiber optic sensor, the first fiber optic sensor will sense the blister box, which means that the blister box is within the positioning range of the positioning component. Then, in conjunction with the controller, the second telescopic cylinder and the third telescopic cylinder will be activated to perform positioning operations on the blister box. The positioning of the blister box can be made more accurate through the first fiber optic sensor.

[0018] Furthermore, a second fiber optic sensor is fixed on the support frame. The second fiber optic sensor is electrically connected to the controller and is located near the closed end of the guide frame.

[0019] By adopting the above technical solution, when the blister box moves to the position of the second fiber optic sensor, the second fiber optic sensor, in conjunction with the controller, can shut off the conveyor belt, avoiding the problems of accumulation and squeezing caused by the continuous conveying of the blister box with the finished lock tongue, which is more conducive to the conveying of the finished lock tongue.

[0020] In summary, this application includes at least one of the following beneficial effects; 1. In this application, multiple blister packs are stacked on a conveyor belt, positioning the stacked finished product storage boxes between multiple positioning strips. The positioning strips are used to position the stacked blister packs, ensuring they are centered. After stacking, two first telescopic cylinders operate simultaneously, driving a clamping plate to clamp the stacked blister packs. Then, the conveyor belt and multi-stage telescopic cylinders begin operation. When the multi-stage telescopic cylinders operate, their telescopic ends extend, driving a pusher plate to move. As the pusher plate moves, it pushes the bottommost blister pack, separating it from the stacked blister packs above. The pusher plate, in conjunction with the conveyor belt, sends the blister pack out of the mounting frame. After being pushed out, the telescopic ends of the multi-stage telescopic cylinders retract, resetting the pusher plate. Then, the two first telescopic cylinders operate again, causing their telescopic ends to move the clamping plate, releasing it from clamping the stacked blister packs. At this point, the stacked blister packs are no longer clamped and fall onto the conveyor belt. Once the blister packs are filled with finished lock tongues, the conveyor belt begins to transport them. At this point, the first and multi-stage telescopic cylinders repeat the feeding action, automatically arranging the blister packs without the need for intermittent manual placement, which is quite convenient. The receiving structure allows processed and inspected lock tongues to be directly inserted into the blister packs, enabling packaging immediately after lock tongue production and inspection, eliminating the need for subsequent manual packaging and improving work efficiency.

[0021] 2. In this application, when the blister pack moves between the two second telescopic cylinders, the conveyor belt stops working. At this time, the second and third telescopic cylinders work simultaneously. When the second telescopic cylinders work, they drive the positioning blocks to abut against the blister pack. By having the two positioning blocks abut against both ends of the finished blister pack, the blister pack can be positioned. When the third telescopic cylinder works, it drives the second positioning blocks to move, so that the right-angle positioning grooves on the second positioning blocks correspond to the corners of the blister pack, further improving the positioning accuracy of the blister pack. Positioning the blister pack using the positioning components can effectively avoid the problem of the blister pack being offset due to collision when placing the finished lock tongue, which is more conducive to the placement of the finished lock tongue.

[0022] 3. In this application, during the conveying process of the blister box, when the blister box moves to the position of the first fiber optic sensor, the first fiber optic sensor will sense the blister box. At this time, it indicates that the blister box is within the positioning range of the positioning component. Then, the first fiber optic sensor sends a signal to the controller. After receiving the signal, the controller sends a control signal to the conveyor belt to stop working, and sends a control signal to the second telescopic cylinder and the third telescopic cylinder to work, thereby performing a positioning operation on the blister box. The first fiber optic sensor can make the positioning of the blister box more accurate, which is more conducive to the placement and conveying of the finished lock tongue.

[0023] 4. In this application, during the conveying process of blister packs filled with finished lock tongues, if the operator fails to retrieve the blister packs filled with finished lock tongues in time, the blister packs continue to be conveyed on the conveyor belt. When the second fiber optic sensor detects the blister pack, it indicates that the blister pack containing the finished lock tongues has been conveyed to the closed end of the guide frame. Then, the second fiber optic sensor sends a signal to the controller. After receiving the signal, the controller sends a control signal to the conveyor belt to stop working and sends a control signal to its built-in buzzer, causing the buzzer to sound an alarm, thereby reminding the operator to retrieve the blister pack containing the finished lock tongues. This effectively avoids the problem of accumulation and compression caused by the continuous conveying of blister packs containing finished lock tongues due to the continuous operation of the conveyor belt, and is more conducive to the conveying of finished lock tongues.

[0026] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0027] This application discloses a latch tongue plastic coating production line.

[0028] Reference Figure 1 and Figure 2 A latch encapsulation production line includes a first base 1, with an injection molding unit 11 for injection molding the latch mounted on the upper end of the first base 1. A second base 12 is disposed on the side of the first base 1, with a feeding unit 13 for feeding materials and a heating unit 14 for heating the latch mounted on the upper end of the second base 12. A third base 15 is disposed on the side of the second base 12 away from the first base 1, with a detection unit 16 for detecting the latch mounted on the upper end of the third base 15. The end of the first base 1 is provided with a detection unit for detecting the latch. The material transfer unit 17 moves the locking tongue. A controller 18 is fixed at the end of the first base 1 away from the material transfer unit 17. A support frame 2 is provided on the side of the third base 15 away from the second base 12. A support frame 21 is fixed at the lower end of the support frame 2. A conveyor belt 22 is installed inside the support frame 2. The controller 18 is electrically connected to the injection molding unit 11, the feeding unit 13, the heating unit 14, the material transfer unit 17, and the conveyor belt 22. A receiving structure for storing finished locking tongues is provided on the support frame 2.

[0029] When the production line is in operation, manual loading of iron parts into the feeding unit 13 is required. Then, the entire production line is started. The feeding unit 13 uses vibration to transport the iron parts to the heating unit 14 in an orderly manner. The heating unit 14 heats the iron parts precisely to 110℃ ± 5℃. After heating, the multi-axis robotic arm of the transfer unit 17 extends into the heating unit 14, removes the heated iron parts, and precisely embeds them into the molding die of the injection molding unit 11. The controller 18 starts the injection molding unit 11, completing the encapsulation molding according to preset parameters. After molding, the die automatically demolds, and the robotic arm re-enters the die to remove the molded latch. After injection molding, the transfer unit 17 transfers the molded latch to the inspection unit 16. The inspection unit 16 inspects each latch individually, checking for missing materials, burrs, and dimensional accuracy. The inspection data is transmitted to the controller 18 in real time. Qualified latches are then fed into the receiving structure, which collects the qualified latches and transports them via the conveyor belt 22. By repeating the above operations, the locking tongue can be processed, inspected, and packaged.

[0030] Reference Figures 2-4 The receiving structure includes a mounting frame 3 fixed on the support frame 2. Multiple positioning strips 31 are fixed on the mounting frame 3. A blister box 32 is placed between the multiple positioning strips 31. A guide frame 33 is fixed on the mounting frame 3. One end of the guide frame 33 is a closed end and the other end is an open end. The open end of the guide frame 33 extends into the interior of the mounting frame 3. The mounting frame 3 is equipped with a clamping component and a pushing component. The support frame 2 is equipped with a positioning component.

[0031] The clamping assembly includes two first telescopic cylinders 34 fixed on the mounting frame 3. The two first telescopic cylinders 34 are symmetrically arranged and electrically connected to the controller 18. The telescopic ends of the first telescopic cylinders 34 are fixed with clamping plates 341. When the two clamping plates 341 clamp the stacked blister boxes 32, the bottommost blister box 32 will not come into contact with the clamping plates 341, thereby ensuring that the subsequent pusher plate 343 can push it out.

[0032] In addition, the material pushing assembly includes a multi-stage telescopic cylinder 342 fixed on the mounting frame 3. The multi-stage telescopic cylinder 342 is electrically connected to the controller 18. A material pushing plate 343 is fixed to the telescopic end of the multi-stage telescopic cylinder 342. The end of the material pushing plate 343 away from the multi-stage telescopic cylinder 342 is attached to the bottommost blister box 32.

[0033] In use, multiple blister boxes 32 are stacked on the conveyor belt 22, so that the stacked finished product storage box is positioned between multiple positioning strips 31. The positioning strips 31 are used to position the stacked blister boxes 32, so that the blister boxes 32 are in the center position. After stacking, the two first telescopic cylinders 34 work simultaneously, extending their telescopic ends and driving the clamping plate 341 to clamp the stacked blister boxes 32. Then, the conveyor belt 22 and the multi-stage telescopic cylinders 342 start working. When the multi-stage telescopic cylinders 342 work, their telescopic ends extend and drive the pusher plate 343 to move. When the pusher plate 343 moves, it pushes the bottommost blister box 32, separating it from the stacked blister boxes 32 above. The pusher plate 343, in conjunction with the conveyor belt 22, sends the blister box 32 out of the mounting frame 3. After being pushed out, the telescopic ends of the multi-stage telescopic cylinders 342 retract, resetting the pusher plate 343. Then, the two first telescopic cylinders 34 work again, causing their telescopic ends to drive the clamping plate 341 to no longer clamp the stacked blister boxes 32. At this time, the stacked blister boxes 32 are no longer clamped and fall onto the conveyor belt 22. Once the blister pack 32 is filled with finished lock tongues, the conveyor belt 22 begins to transport the blister pack 32. At this time, the first telescopic cylinder 34 and the multi-stage telescopic cylinder 342 repeat the feeding action to achieve automatic arrangement of the blister packs 32, eliminating the need for intermittent manual placement, which is more convenient. The receiving structure allows the processed and inspected lock tongues to be directly inserted into the blister pack 32, enabling boxing immediately after lock tongue production and inspection, eliminating the need for subsequent manual boxing and improving work efficiency.

[0034] Reference Figure 3 and Figure 5 The positioning assembly includes two second telescopic cylinders 35 fixed on the support frame 2. The two second telescopic cylinders 35 are symmetrically arranged and electrically connected to the controller 18. A first positioning block 351 is fixed to the telescopic end of the second telescopic cylinder 35. Positioning grooves adapted to the positioning blocks are opened at both ends of the blister box 32. The first positioning block 351 is located above the conveyor belt 22, and the side of the first positioning block 351 away from the second telescopic cylinder is used to abut against the end of the blister box 32.

[0035] The positioning component also includes a third telescopic cylinder 352 fixed on the support frame 2. The telescopic end of the third telescopic cylinder 352 is fixed with a second positioning block 353. The third telescopic cylinder 352 is electrically connected to the controller 18.

[0036] In addition, the second positioning block 353 is located above the conveyor belt 22, and a right-angle positioning groove is provided on the second positioning block 353. The right-angle positioning groove is used to abut the corner of the blister box 32.

[0037] When the blister box 32 moves between the two second telescopic cylinders 35, the conveyor belt 22 stops working. At this time, the second telescopic cylinders 35 and the third telescopic cylinder 352 work simultaneously. When the second telescopic cylinder 35 works, its telescopic end extends, causing the first positioning block 351 to abut against the blister box 32. By having the two positioning blocks abut against both ends of the finished blister box 32, the blister box 32 can be positioned. When the third telescopic cylinder 352 works, its telescopic end extends, causing the second positioning block 353 to move, so that the right-angle positioning groove on the second positioning block 353 corresponds to the corner of the blister box 32, further improving the positioning accuracy of the blister box 32. By positioning the blister box 32 through the positioning components, the problem of the blister box 32 being offset due to collision when placing the finished lock tongue can be effectively avoided, which is more conducive to the placement of the finished lock tongue. When the blister pack 32 that has been sent out of the mounting frame 3 on the conveyor belt 22 is filled with finished product locking tongue, the telescopic ends of the second telescopic cylinder 35 and the third telescopic cylinder 352 begin to retract, no longer positioning the blister pack 32, and the conveyor belt 22 starts to work, transporting the blister pack 32 filled with finished products.

[0038] Reference Figure 5 and Figure 6 A first fiber optic sensor 36 is fixed on the support frame 2, and the first fiber optic sensor 36 is electrically connected to the controller 18.

[0039] The first fiber optic sensor 36 is located on one side of the second telescopic cylinder 35 and corresponds to the position of the third telescopic cylinder 352.

[0040] During the conveying process of the blister box 32, when the blister box 32 moves to the position of the first fiber optic sensor 36, the first fiber optic sensor 36 will sense the blister box 32. At this time, it means that the blister box 32 is within the positioning range of the positioning component. Then, the first fiber optic sensor 36 sends a signal to the controller 18. After receiving the signal, the controller 18 sends a control signal to the conveyor belt 22 to stop it from working, and sends a control signal to the second telescopic cylinder 35 and the third telescopic cylinder 352 to make the second telescopic cylinder 35 and the third telescopic cylinder 352 work, thereby performing a positioning operation on the blister box 32. The first fiber optic sensor 36 can make the positioning of the blister box 32 more accurate, which is more conducive to the placement and conveying of the finished lock tongue.

[0041] A second fiber optic sensor 37 is fixed on the support frame 2. The second fiber optic sensor 37 is electrically connected to the controller 18. The second fiber optic sensor 37 is located near the closed end of the guide frame 33.

[0042] During the conveying process of the blister box 32 filled with finished lock tongues, if the operator fails to pick up the finished blister box 32 filled with finished lock tongues in time, the blister box 32 continues to be conveyed on the conveyor belt 22. When the second fiber optic sensor 37 senses the blister box 32, it indicates that the blister box 32 containing finished lock tongues has been conveyed to the closed end of the guide frame 33. Then, the second fiber optic sensor 37 sends a signal to the controller 18. After receiving the signal, the controller 18 sends a control signal to the conveyor belt 22 to stop it from working and sends a control signal to its built-in buzzer to make the buzzer sound an alarm, thereby reminding the operator to pick up the blister box 32 containing finished lock tongues. This can effectively avoid the problem of accumulation and squeezing caused by the continuous conveying of the blister box 32 containing finished lock tongues due to the continuous operation of the conveyor belt 22, and is more conducive to the conveying of finished lock tongues.

[0043] Working principle: When this production line is working, the loading unit 13 needs to be filled with iron parts manually first, and then multiple blister boxes 32 are stacked on the conveyor belt 22, so that the stacked finished product storage boxes are positioned between multiple positioning strips 31. The positioning strips 31 are used to position the stacked blister boxes 32, so that the blister boxes 32 are in the center position. After stacking, the two first telescopic cylinders 34 work simultaneously, so that their telescopic ends extend and drive the clamping plate 341 to clamp the stacked blister boxes 32. Then the conveyor belt 22 and the multi-stage telescopic cylinders 342 start to work. When the multi-stage telescopic cylinders 342 are working, The telescopic end of the cylinder extends and drives the pusher plate 343 to move. When the pusher plate 343 moves, it pushes the bottommost blister box 32, separating it from the stacked blister boxes 32 above. The pusher plate 343, in conjunction with the conveyor belt 22, sends the blister box 32 out of the mounting frame 3. After being pushed out, the telescopic end of the multi-stage telescopic cylinder 342 retracts, bringing the pusher plate 343 back to its original position. Then, the two first telescopic cylinders 34 work again, causing their telescopic ends to drive the clamping plate 341 to stop clamping the stacked blister boxes 32. At this time, the stacked blister boxes 32 are no longer clamped and fall onto the conveyor belt 22. During the conveying process of the blister box 32, when the blister box 32 moves to the position of the first fiber optic sensor 36, the first fiber optic sensor 36 will sense the blister box 32. At this time, it means that the blister box 32 is within the positioning range of the positioning component. Then, the first fiber optic sensor 36 sends a signal to the controller 18. After receiving the signal, the controller 18 sends a control signal to the conveyor belt 22 to stop it from working, and sends a control signal to the second telescopic cylinder 35 and the third telescopic cylinder 352 to make the second telescopic cylinder 35 and the third telescopic cylinder 352 work. When the second telescopic cylinder 35 works, its telescopic end extends and drives the first positioning block 351 to abut against the blister box 32. By having the two positioning blocks abut against both ends of the finished blister box 32, the positioning of the blister box 32 can be achieved. When the third telescopic cylinder 352 works, its telescopic end extends and drives the second positioning block 353 to move, so that the right angle positioning groove on the second positioning block 353 corresponds to the corner of the blister box 32, further improving the positioning accuracy of the blister box 32. Afterwards, the entire production line is started. At this time, the feeding unit 13 conveys the iron parts to the heating unit 14 in an orderly manner through vibration. The heating unit 14 heats the iron parts to a precise temperature of 110℃ ± 5℃. After heating, the multi-axis robotic arm of the transfer unit 17 extends into the heating unit 14, removes the heated iron parts, and precisely embeds them into the molding mold of the injection molding unit 11. The controller 18 starts the injection molding unit 11 and completes the plastic coating molding according to the preset parameters. After molding, the mold is automatically demolded, and the robotic arm extends into the mold again to remove the molded lock tongue. After the injection molding unit completes the injection molding, the transfer unit 17 transfers the molded lock tongue to the detection unit 16. The detection unit 16 inspects each lock tongue to check for missing materials, burrs, and whether the dimensions are qualified. The detection data is transmitted to the controller 18 in real time. During the inspection process, qualified lock tongues are sent to the blister box 32 of the mounting frame 3 on the conveyor belt 22, while unqualified lock tongues fall into the recycling box in the detection unit, achieving precise diversion. As the lock tongues are produced, once the blister packs 32 on the conveyor belt 22, which have been fed from the mounting frame 3, are filled with finished lock tongues, the telescopic ends of the second telescopic cylinder 35 and the third telescopic cylinder 352 begin to retract, ceasing to position the blister packs 32. The conveyor belt 22 then begins to transport the blister packs 32 filled with finished lock tongues. At this time, the first telescopic cylinder 34 and the multi-stage telescopic cylinder 342 repeat the feeding action to achieve automatic arrangement of the blister packs 32, while the second telescopic cylinder 35 and the third telescopic cylinder 352 repeat the positioning work. This process is repeated to achieve the production, inspection, and packaging of the lock tongues.
