Description

Technical Field

[0001] This utility model relates to the field of headphone case assembly technology, and in particular to a headphone case top card assembly machine with positioning and calibration function. Background Technology

[0002] The headphone box top card machine is an automated device used in the production of headphone packaging boxes. Its main function is to accurately insert the top card into the box. It realizes the feeding, positioning and pressing processes through mechanical structure, replacing manual operation, improving assembly efficiency and consistency. It is suitable for the exquisite packaging of TWS headphones, ensuring that the top card fits tightly with the box, avoiding loosening, ensuring the packaging is beautiful and the product is protected. It is used in the packaging stage of headphone production line.

[0003] To meet the automation requirements of headphone packaging, the process is as follows: after empty boxes and top cards are fed separately, they are positioned by vision or mechanical means. The top card is pressed into the box according to the set pressure and stroke. Then, in-place, missing, and reversed inspections are carried out. Qualified products are unloaded. When an abnormality occurs, an alarm is automatically triggered or defective products are rejected. Some models will pre-fold the top card before inserting it into place to achieve multi-station parallel operation.

[0004] During equipment operation, if an open-loop system is used for pressure and stroke control, it is difficult to adjust in real time according to the slight differences in the material and thickness of the packaging box. This often results in problems such as the top card being pressed too deeply and damaging the box, or not being pressed in properly and causing the product to loosen. In the positioning stage, traditional visual or mechanical secondary positioning methods are affected by ambient light and dirt on the surface of the material, resulting in insufficient positioning accuracy and the top card and the box cannot be accurately aligned. Utility Model Content

[0009] The clamping mechanism includes two fixed plates. The bottom ends of the adjacent sides of the two fixed plates are fixedly connected to the middle of the front and rear sides of the bracket, respectively. The top of the adjacent sides of the multiple fixed plates are fixedly connected to telescopic blocks one. The adjacent sides of the multiple telescopic blocks one are fixedly connected to telescopic blocks two. The adjacent sides of the multiple telescopic blocks two are fixedly connected to baffles. The left and right ends of the multiple baffles are fixedly connected to connecting blocks. The opposite sides of the multiple connecting blocks are fixedly connected to clamping plates.

[0010] As a further description of the above technical solution:

[0011] The outer sides of the multiple rollers are designed to be non-slip, and the outer walls of the multiple rollers are symmetrically distributed along the central axis of the sliding member.

[0012] As a further description of the above technical solution:

[0013] The outer walls of both baffles are made of nitrile rubber, and the outer edges of the clamps are chamfered.

[0014] As a further description of the above technical solution:

[0015] The operating mechanism includes a motor, the rear of which is fixedly connected to the front left end of the conveyor belt. A support block is fixedly connected to the top rear side of the conveyor belt, and a feeding component is provided on the top of the support block. A waste plate is fixedly connected to the front right end of the conveyor belt, a pushing component is provided on the rear right end of the conveyor belt, and an interaction component is provided on the front left end of the conveyor belt. A detection door is fixedly connected to the top middle section of the conveyor belt, and a camera is fixedly connected to the top inside the detection door.

[0016] As a further description of the above technical solution:

[0017] The feeding assembly includes a rotating shaft, which is rotatably connected inside a support block. A rotating groove is provided at the top center of the support block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, two sliding parts slide on the front and rear sides of the left top of the conveyor belt, driving rotating column one and rotating column two to move. Rotating column two causes telescopic rod one to slide on the outer wall of telescopic rod two, adjusting the distance between the sliding parts. The roller on the adjacent side of the sliding parts contacts the packaging box, and under the action of the sliding parts, it rolls and pushes the packaging box, so that the packaging box is balanced by force and its position is accurately adjusted, improving the positioning stability and reducing operational errors caused by position deviation.

[0024] 2. In this utility model, two fixed plates provide support for the entire mechanism. When the telescopic block one on the fixed plate is activated, it drives the telescopic block two to move in the adjacent direction. The telescopic block two drives the baffle to move. The baffle drives the clamping plate to approach the packaging box through the connecting block. The distance between the clamping plates is adjusted by the telescopic blocks one and two until the clamping plate clamps the packaging box, thus achieving a stable fixation of the packaging box, preventing it from shifting during the top clamping operation, ensuring the accuracy of the top clamping, and adapting to packaging boxes of different specifications.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-5 An embodiment of this utility model is provided: a headphone box top card machine with positioning calibration function, including a bracket 1, a conveyor belt 2 fixed to the top of the bracket 1, an adjustment mechanism 3 provided on the top of the bracket 1, the adjustment mechanism 3 is used to calibrate the position of the packaging box, a clamping mechanism 4 is provided on the middle side of the top of the bracket 1, the clamping mechanism 4 is used to fix the position of the packaging box, and an operating mechanism 5 is provided on the top of the conveyor belt 2.

[0035] The adjustment mechanism 3 includes two sliding members 31. The two sliding members 31 are slidably connected to the front and rear sides of the top left end of the conveyor belt 2 on opposite sides. Rotating column 1 32 is fixedly connected to the right end of the opposite side of the multiple sliding members 31. Rotating column 2 33 is rotatably connected to the left end of the opposite side of the multiple sliding members 31. Telescopic rod 1 34 is fixedly connected to the outer wall of the two rotating column 2 33. Telescopic rod 2 35 is slidably connected to the outer wall of the multiple telescopic rod 1 34. Multiple rollers 36 are provided on the adjacent side of the multiple sliding members 31.

[0036] Specifically, the packaging box is conveyed to the top of the conveyor belt 2. The adjusting mechanism 3 is activated to calibrate the position of the packaging box. Two sliding members 31 slide on the front and rear sides of the top left end of the conveyor belt 2, driving the rotating column 1 32 and rotating column 2 33 to move. The rotation of rotating column 2 33 causes telescopic rod 1 34 to slide on the outer wall of telescopic rod 2 35. Through the relative movement of telescopic rod 1 34 and telescopic rod 2 35, the distance between the two sliding members 31 is adjusted. Multiple rollers 36 on the adjacent side of the sliding member 31 contact the packaging box. Driven by the sliding member 31, the rollers 36 roll and push the packaging box. The packaging box is moved to a preset position on the conveyor belt 2 to achieve initial position calibration. After the packaging box is calibrated by the adjustment mechanism 3, the conveyor belt 2 transports it to the clamping mechanism 4. The clamping mechanism 4 actuates to fix the position of the packaging box. After the clamping mechanism 4 fixes the packaging box, the operating mechanism 5 performs a top clamping operation on the top of the conveyor belt 2. After the top clamping operation is completed, the clamping mechanism 4 releases the fixation on the packaging box, and the conveyor belt 2 transports the top-clamped packaging box to the next process. At the same time, the adjustment mechanism 3 resets, ready to calibrate the position of the next incoming packaging box.

[0037] Reference Figure 4 The clamping mechanism 4 includes two fixed plates 41. The bottom ends of the adjacent sides of the two fixed plates 41 are fixedly connected to the middle of the front and rear sides of the bracket 1, respectively. The top of the adjacent sides of the multiple fixed plates 41 are fixedly connected to telescopic blocks 1 42. The adjacent sides of the multiple telescopic blocks 1 42 are fixedly connected to telescopic blocks 2 43. The adjacent sides of the multiple telescopic blocks 2 43 are fixedly connected to baffles 44. The left and right ends of the multiple baffles 44 are fixedly connected to connecting blocks 45, and the opposite sides of the multiple connecting blocks 45 are fixedly connected to clamping plates 46.

[0038] Specifically, when the packaging box, after being calibrated by the adjustment mechanism 3, is conveyed to the clamping mechanism 4 by the conveyor belt 2, the clamping mechanism 4 begins to work. Two fixing plates 41 are fixed to the middle of the front and rear sides of the bracket 1, providing support for the entire clamping mechanism 4. The telescopic block 42 on the top of the adjacent side of the fixing plate 41 is activated, causing the telescopic block 43 to move in the adjacent direction. As the telescopic block 43 moves, the baffle 44 on its adjacent side moves synchronously. The connecting blocks 45 at both ends of the baffle 44 then move the clamping plate 46 closer to the packaging box. Through the telescopic movements of the telescopic block 42 and the telescopic block 43, the distance between the two clamping plates 46 is adjusted. The clamping plate 46 contacts and clamps the packaging box, thus fixing the packaging box. During the top clamping operation of the packaging box by the operating mechanism 5, the clamping mechanism 4 maintains the fixed state of the packaging box. The clamping force of the clamping plate 46 prevents the packaging box from shifting during the top clamping. After the top clamping operation is completed, the telescopic block 1 42 drives the telescopic block 2 43 to move away from each other. The baffle 44, connecting block 45 and clamping plate 46 are then reset, releasing the fixing of the packaging box. The conveyor belt 2 transports the top clamped packaging box to the next process. The clamping mechanism 4 is then ready to fix the next incoming packaging box, ensuring that the entire top clamping operation is carried out continuously and stably.

[0039] Reference Figures 3-6 The outer sides of multiple rollers 36 are designed to be non-slip. The outer walls of multiple rollers 36 are symmetrically distributed along the central axis of the sliding member 31. The outer walls of the two baffles 44 are made of nitrile rubber. The outer edges of the clamping plate 46 are chamfered. The operating mechanism 5 includes a motor 51. The rear side of the motor 51 is fixedly connected to the front left end of the conveyor belt 2. The rear top of the conveyor belt 2 is fixedly connected to a support block 58. The top of the support block 58 is provided with a feeding component 53. The front right end of the conveyor belt 2 is fixedly connected to a waste plate 52. The rear right end of the conveyor belt 2 is provided with a pushing component 54. The front left end of the conveyor belt 2 is provided with an interactive component 55. The top middle part of the conveyor belt 2 is fixedly connected to a detection door 56. The top inside the detection door 56 is fixedly connected to a camera 57.

[0040] Specifically, when the packaging box is conveyed to the adjusting mechanism 3, multiple rollers 36, with their anti-slip design on the outside, enhance the friction with the surface of the packaging box. Furthermore, their outer walls are symmetrically distributed along the central axis of the sliding member 31, ensuring the packaging box remains balanced under force. Through the movement of the sliding member 31 and the rolling of the rollers 36, the packaging box is pushed to a preset position for precise calibration. The calibrated packaging box is then conveyed by the conveyor belt 2 to the clamping mechanism 4. Two fixed plates 41 provide stable support for the clamping mechanism 4. The first telescopic block 42 on the fixed plate 41 is activated, causing the second telescopic block 43 to move in an adjacent direction. This, in turn, causes the baffle 44 and connecting block 45 to bring the clamping plate 46 closer to the packaging box. Since the outer wall of the baffle 44 is made of nitrile rubber... Furthermore, the outer edge of the clamping plate 46 is chamfered to avoid damage when it comes into contact with the packaging box. The distance between the clamping plates 46 is adjusted and the packaging box is clamped and fixed by the telescopic movement of telescopic block 1 42 and telescopic block 2 43. In the operating mechanism 5, the motor 51 provides power for the operation of the equipment. The feeding component 53 on the top of the support block 58 transports the top clamp to the assembly position. After the top clamping operation is completed, the packaging box is transported to the inspection door 56 by the conveyor belt 2. The camera 57 at the top of the inspection door 56 inspects it. If the inspection fails, the push component 54 pushes the defective product to the waste plate 52; if it passes, it is transported to the next process. The interactive component 55 is used for the operation and status display of the equipment to ensure that the equipment can complete the top clamping operation continuously and stably.

[0041] Reference Figures 2-5 The feeding component 53 includes a rotating shaft 532, which is rotatably connected to the inside of the support block 58. A rotating groove 531 is provided in the middle of the top of the support block 58. A robotic arm 533 is fixedly connected to the top of the rotating shaft 532. An adsorption plate 534 is fixedly connected to the left side of the robotic arm 533. The pushing component 54 includes a support plate 541. The lower front end of the support plate 541 is fixedly connected to the right rear end of the waste plate 52. A telescopic member 542 is fixedly connected to the upper front end of the support plate 541. A push plate 543 is fixedly connected to the front side of the telescopic member 542. The interactive component 55 includes an interactive body 551. The rear side of the interactive body 551 is fixedly connected to the left front end of the conveyor belt 2. A screen 552 is fixedly connected to the left front end of the interactive body 551. A button 553 is fixedly connected to the right front end of the interactive body 551.

[0042] Specifically, after the clamping mechanism 4 fixes the packaging box, the feeding assembly 53 starts working. The rotating shaft 532 inside the support block 58 rotates, and the robotic arm 533 at its top rotates with the rotating shaft 532 in the rotating groove 531 at the top center of the support block 58. The suction plate 534 on the left side of the robotic arm 533 moves to the top card storage area and suctions the top card. Through the rotation of the rotating shaft 532 and the movement of the robotic arm 533, the top card is moved to the assembly position of the packaging box, completing the top card feeding operation. When the top card is assembled and detected as a defective product by the camera 57 inside the detection gate 56, the push assembly 54 is started, and the support plate 54... 1 provides support for the telescopic component 542. The telescopic component 542 extends, driving the front push plate 543 to move forward. The push plate 543 contacts the defective product and pushes it to the waste plate 52, thereby removing the defective product. In the interactive component 55, the interactive main body 551 is fixed to the front left end of the conveyor belt 2. The operator can view the equipment operation status through the screen 552 on the front left end of the interactive main body 551, and set parameters and control the operation through the button 553 on the front right end. Through the precise feeding of the feeding component 53, the efficient removal of the push component 54, and the convenient operation of the interactive component 55, the top card operation is ensured to be stable and orderly.

[0043] Working principle: The packaging box is conveyed to the top of the conveyor belt 2. The adjustment mechanism 3 is activated to calibrate the position of the packaging box. Two sliding parts 31 slide on the front and back sides of the top left end of the conveyor belt 2, driving the rotating column 1 32 and rotating column 2 33 to move. The rotation of rotating column 2 33 causes telescopic rod 1 34 to slide on the outer wall of telescopic rod 2 35. Through the relative movement of telescopic rod 1 34 and telescopic rod 2 35, the distance between the two sliding parts 31 is adjusted. Multiple rollers 36 on the adjacent side of the sliding parts 31 contact the packaging box. The multiple rollers 36 have an anti-slip design on the outside, which enhances the friction with the surface of the packaging box. Their outer walls are symmetrically distributed along the central axis of the sliding parts 31, so that the packaging box remains balanced when subjected to force. Driven by the sliding parts 31, the rollers 36 roll and push the packaging box, so that the packaging box moves to the preset position on the conveyor belt 2. Through the movement of the sliding parts 31 and the rolling of the rollers 36, the precise calibration of the packaging box is achieved.

[0044] After the packaging box is calibrated by the adjustment mechanism 3, the conveyor belt 2 transports it to the clamping mechanism 4. The clamping mechanism 4 starts to move to fix the position of the packaging box. Two fixing plates 41 are fixed in the middle of the front and rear sides of the bracket 1, respectively, to provide stable support for the entire clamping mechanism 4. The telescopic block 42 on the top of the adjacent side of the fixing plate 41 is activated, which drives the telescopic block 43 to move in the adjacent direction. As the telescopic block 43 moves, the baffle 44 on the adjacent side moves synchronously. The connecting blocks 45 at the left and right ends of the baffle 44 then drive the clamping plate 46 to approach the packaging box. Since the outer wall of the baffle 44 is made of nitrile rubber and the outer edge of the clamping plate 46 is chamfered, it can avoid damage when contacting the packaging box. Through the telescopic movement of the telescopic block 42 and the telescopic block 43, the distance between the two clamping plates 46 is adjusted until the clamping plate 46 contacts the packaging box and clamps it, thereby fixing the packaging box.

[0045] After the clamping mechanism 4 fixes the packaging box, the operating mechanism 5 performs a top clamping operation on the packaging box at the top of the conveyor belt 2. The rear side of the motor 51 is fixedly connected to the front left end of the conveyor belt 2 to provide power for the operation of the equipment. The feeding component 53 at the top of the support block 58 transports the top clamp to the assembly position. The specific working process of the feeding component 53 is as follows: the rotating shaft 532 inside the support block 58 rotates, and the robotic arm 533 at its top rotates with the rotating shaft 532 in the rotating groove 531 at the top center of the support block 58. The adsorption plate 534 on the left side of the robotic arm 533 moves to the top clamp storage position and adsorbs the top clamp. Through the rotation of the rotating shaft 532 and the movement of the robotic arm 533, the top clamp is moved to the assembly position of the packaging box to complete the top clamp feeding operation.

[0046] During the top clamping operation of the operating mechanism 5 on the packaging box, the clamping mechanism 4 keeps the packaging box in a fixed state. The clamping force of the clamping plate 46 prevents the packaging box from shifting during the top clamping. After the top clamping operation is completed, the telescopic block 1 42 drives the telescopic block 2 43 to move away from each other. The baffle 44, the connecting block 45 and the clamping plate 46 are then reset, and the clamping mechanism 4 releases the fixation of the packaging box.

[0047] Conveyor belt 2 transports the finished packaging box to inspection gate 56. A camera 57 is fixedly connected to the top of the inside of inspection gate 56. The camera 57 inspects the packaging box. If the inspection fails, the push assembly 54 is activated. The lower front end of the support plate 541 is fixedly connected to the right rear end of the waste plate 52, providing support for the telescopic component 542. The telescopic component 542 extends, driving the push plate 543 on the front side to move forward. The push plate 543 contacts the defective product and pushes it to the waste plate 52 on the right front end of conveyor belt 2, thus removing the defective product. If the inspection is successful, the packaging box is transported to the next process by conveyor belt 2.

[0048] The rear side of the interactive component 55 is fixedly connected to the front left end of the conveyor belt 2. The front left end of the interactive main body 551 is fixedly connected to the screen 552, and the front right end is fixedly connected to the button 553. The operator can view the equipment operation status through the screen 552 and set parameters and control the operation through the button 553.

[0049] After completing the top clamping operation for one packaging box, the adjustment mechanism 3 resets, ready to calibrate the position of the next incoming packaging box. The clamping mechanism 4 is also ready to fix the next incoming packaging box, ensuring that the entire top clamping operation is carried out continuously and stably.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
