Description

Technical Field

[0001] This utility model relates to the field of mobile phone case processing technology, specifically a plastic tray feeding and handling device. Background Technology

[0002] In automated mobile phone case packaging production lines, plastic trays serve as the carrier and protective components for the phone cases. Their efficient and precise feeding and handling are crucial for ensuring the smooth operation of the entire packaging process. Plastic trays are typically injection-molded from plastic and feature a specific groove structure that precisely matches the shape of the phone case. During transportation and storage, they provide stable support, preventing surface wear or structural damage caused by collisions or compression. Therefore, they are indispensable in the mobile phone case packaging process. Traditional plastic pallet loading and handling relies heavily on manual operation or semi-automated equipment, presenting numerous problems that urgently need to be addressed. In manual operation, workers must separate, move, and place stacked plastic pallets one by one to designated conveyor positions, resulting in high labor intensity and extremely low efficiency. Because plastic pallets may attract or jam when stacked, manual separation often requires additional time, severely restricting the overall production line cycle time. Furthermore, the positioning accuracy of manually placed plastic pallets is difficult to guarantee, easily leading to pallet misalignment and tilting. This causes positioning deviations in subsequent phone case and pallet assembly processes, affecting packaging quality and increasing the defect rate.

[0003] With the continuous growth of demand in the mobile phone case market and the accelerated pace of product upgrades, production lines are placing higher demands on the efficiency, precision, and automation of plastic tray loading and handling. Traditional methods can no longer meet the needs of large-scale, fast-paced production, not only increasing labor costs and management difficulties for enterprises but also making it difficult to guarantee product quality stability. Therefore, developing a device that can achieve automatic separation, precise loading, and stable handling of plastic trays has become an urgent need to improve the automation level of mobile phone case packaging production lines, reduce production costs, and improve product quality. To this end, this utility model provides a plastic tray loading and handling device. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] This utility model provides two technical solutions: Figures 1-10 The first embodiment is shown: a plastic pallet loading and conveying device, including a loading component 1, and a conveying component 2 is provided on one side of the loading component 1; The feeding assembly 1 includes a first mounting frame 11. Two limiting frames 17 are provided at the top of the first mounting frame 11. A fixing frame 18 is fixedly installed at the top of the two limiting frames 17. A set of first sliding rods 19 slides through one side of the outer wall of the fixing frame 18. A clamping plate 111 is fixedly installed at one end of the outer wall of the set of first sliding rods 19. A spring 110 is sleeved on the outer wall of the set of first sliding rods 19. The two ends of the outer wall of the set of springs 110 are fixedly connected to the outer wall of the clamping plate 111 and the outer wall of the fixing frame 18, respectively. A wedge structure is provided on one side of the outer wall of the clamping plate 111. Under the action of the spring 110, the wedge separates the uppermost plastic tray from the lower plastic tray unit group, ensuring that the suction cup can accurately adsorb a single plastic tray. When the plastic tray unit group is lifted upward, the clamping plate 111 is slightly separated to both sides under the action of the spring 110, ensuring that it does not hinder the overall rise of the plastic tray unit group. At the same time, the elastic force of the spring 110 continues to act on the edge of the plastic support, ensuring that there is always an upward force during the upward movement of the plastic support unit group, so that the uppermost plastic support and the lower plastic support unit group are kept in a certain separation state.

[0017] The handling assembly 2 includes a second mounting frame 21, a rotating frame 25 is rotatably mounted on the top of the second mounting frame 21, a set of mounting plates 27 is fixedly mounted on the top of the rotating frame 25, a lifting rod 28 slides through the mounting plate 27, a pulley 29 is fixedly mounted on the top of the lifting rod 28, a pneumatic suction cup 26 is fixedly mounted on the bottom of the lifting rod 28, a circular guide rail 210 is slidably mounted on the top of the set of pulleys 29, and a set of cams 212 is mounted on the top of the circular guide rail 210.

[0018] The top of the first mounting frame 11 is fixedly mounted with a first mounting shell 12. Two irregular gears 13 are rotatably mounted on the inner wall of the first mounting shell 12. The two irregular gears 13 are meshed with each other. A multi-link rotating arm 14 is fixedly mounted on one end of the outer wall of the two irregular gears 13. One end of the outer wall of the multi-link rotating arm 14 is rotatably connected to one end of the outer wall of the limiting frame 17.

[0019] A first servo motor 16 is fixedly installed at the top of the first mounting shell 12. The output end of the first servo motor 16 passes through the inner wall of the first mounting shell 12 and is fixedly installed with a first gear 15. The first gear 15 is meshed with the outer wall of one of the two irregular gears 13. A frame 112 is fixedly installed at the bottom of the first mounting bracket 11. A second servo motor 113 is fixedly installed on the outer wall of the frame 112.

[0020] Figures 1-10 The second embodiment is shown, and its main difference from the first embodiment is that: a lifting frame 114 is slidably provided on the inner wall of the frame 112, a lifting plate 116 is fixedly installed on the top of the lifting frame 114, racks 115 are provided on both sides of the inner wall of the lifting frame 114, and two second gears 117 are rotatably installed on the outer wall of the frame 112. The two second gears 117 are meshed with each other and respectively mesh with the two racks 115. The output end of the second servo motor 113 passes through the outer wall of the frame 112 and is fixedly connected to the outer wall of one of the two second gears 117. When the second servo motor 113 is started, it can drive one of the second gears 117 to rotate. At this time, the other second gear 117 will rotate, and then the two second gears 117 drive the lifting frame 114 to rise and fall through the two racks 115.

[0021] The top of the second mounting bracket 21 is fixedly mounted with a second mounting shell 213, and the bottom of the second mounting shell 213 is fixedly mounted with a third servo motor 22. The output end of the third servo motor 22 passes through the inner wall of the second mounting shell 213 and is fixedly mounted with a drive wheel 23. A grooved wheel 24 is meshed on one side of the outer wall of the drive wheel 23. The drive wheel 23 is equipped with multiple crank pins, and the grooved wheel 24 is provided with radial grooves that match the crank pins. This configuration enables the plastic tray conveying device to stop and start precisely within a specific time interval, ensuring the stability and accuracy of the pneumatic suction cup 26 when picking up the plastic tray.

[0022] The grooved wheel 24 is rotatably mounted on the inner wall of the second mounting housing 213, and the top end of the grooved wheel 24 is fixedly connected to the rotating frame 25.

[0023] A fixing frame 211 is fixedly installed at the top of the circular guide rail 210 to fix the circular guide rail 210. The pulley 29 is slidably set with the inner wall of the circular guide rail 210 and a set of cams 212. When the pulley 29 slides on the inner wall of the circular guide rail 210 and the cams 212, it can drive the pneumatic suction cup 26 to move.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] During operation, the feeding assembly 1 is responsible for limiting and fixing the plastic tray unit group, automatically separating it, and continuously pushing it upwards. When the plastic tray unit group is conveyed to the predetermined position, the first servo motor 16 drives the first gear 15 to rotate. The first gear 15 drives one of the two meshing irregular gears 13 to rotate, and then through the meshing transmission of the two irregular gears 13, the multi-link rotating arm 14 drives the limiting frame 17 to close inward from the open state. When it closes to the set angle, the limiting frame 17 clamps and fixes the plastic tray unit group. At the same time, the high baffle behind the fixing frame 18 rises synchronously to prevent the plastic tray unit group from collapsing and ensure the limiting stability. The plastic tray unit separation mechanism works synchronously: a spring 110 is sleeved on the outer wall of the first slide rod 19 on the fixed frame 18. The spring 110 pushes the clamping plate 111 to precisely engage with the gap between the top and second plastic trays. The separation of a single tray is achieved by using the wedge structure and the separation force of the spring 110. After the top plastic tray is sucked away, the second servo motor 113 drives two meshing second gears 117 to rotate. Through the meshing transmission between the second gears 117 and the rack 115, the lifting frame 114 and the lifting plate 116 are lifted upward, just enough to bring the new top plastic tray to the separation position, completing the cyclic feeding.

[0026] The conveying assembly 2 achieves stable transport of the plastic tray through intermittent motion and cam 212 control. The third servo motor 22 drives the drive wheel 23 to rotate, and its crank pin is sequentially embedded in the radial groove of the grooved wheel 24, causing the grooved wheel 24 and the top rotating frame 25 to perform intermittent motion. When the pneumatic suction cup 26 moves above the plastic tray, the grooved wheel mechanism pauses the device, providing time for the suction action. The mounting plate 27 on the rotating frame 25 passes through the lifting rod 28, and the top pulley 29 slides along the circular guide rail 210 and the cam 212. When the pulley 29 enters the downward bending section of the guide rail, the contour of the cam 212 guides the lifting rod 28 to drive the pneumatic suction cup 26 to move downward slightly, and after contacting the plastic tray, it is adsorbed by negative pressure. After adsorption is completed, the grooved wheel mechanism drives the rotating frame 25 to continue rotating, and the pulley 29 returns to its original position along the guide rail, causing the suction cup to rise. Finally, it descends again above the conveyor belt guided by the cam 212, releasing the plastic tray to the designated position, realizing the automated process of "pickup-transfer-placement".
