Description

Technical Field

[0001] This utility model relates to the technical field of POS machine assembly, and in particular to a zebra strip frame automatic loading and unloading component for an intelligent POS terminal product. Background Technology

[0002] In the production process of smart POS terminal products, zebra strips need to be installed inside zebra strip frames to connect the display screen and motherboard, among other components. Traditionally, loading and unloading of LCD zebra strip frames is mostly done manually, which has many drawbacks. Firstly, manual loading and unloading is inefficient, making it difficult to meet the demands of large-scale, high-efficiency production, leading to longer production cycles and increased production costs. Secondly, the precision of manual operation is difficult to guarantee; frequent loading and unloading can easily damage the LCD zebra strip frames, affecting product quality and reducing the production pass rate. Furthermore, manual operation also suffers from high labor intensity and is greatly affected by human factors, which is detrimental to the stability and continuity of production.

[0003] In view of this, this utility model was developed by deeply exploring the many shortcomings and inconveniences of the existing manual loading and unloading of zebra strip frames, and through active research, improvement and trial production. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic loading and unloading device for zebra strip frames, so as to improve production efficiency, ensure product quality and reduce production costs.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] An automatic loading and unloading device for LCD zebra strip frames includes a support frame and a loading vibratory plate, a positioning seat, an assembly turntable, a transfer mechanism and a unloading module mounted on the support frame.

[0007] The positioning seat is set on one side of the feeding vibratory plate, and the positioning seat, assembly turntable and unloading module are arranged side by side at equal intervals in sequence;

[0008] The assembly turntable has a rotating base and two mounting bases for clamping or releasing the zebra strip frame, the two mounting bases being fixed to opposite ends of the rotating base;

[0009] The transfer mechanism includes a moving component, a sliding bracket, a lifting module, a double-claw bracket, and transfer claws. The moving component is movably disposed at one end of the positioning seat, the assembly turntable, and the unloading module. The sliding bracket is connected to the moving component. The lifting module is disposed on the sliding bracket. The double-claw bracket is fixedly disposed at the top of the lifting module and moves up and down with the lifting module. The two transfer claws are spaced apart at both ends of the double-claw bracket facing the assembly turntable. The moving module drives the sliding bracket and its lifting module, double-claw bracket, and transfer claws to move between the positioning seat, the assembly turntable, and the unloading module, so that the two transfer claws transfer between the positioning seat and the assembly turntable or between the assembly turntable and the unloading module.

[0010] Furthermore, the moving module includes a linear slide rail, a linear slide block, and a linear cylinder. The linear slide rail is fixedly installed on one side of the positioning seat, the assembly turntable, and the unloading module. The linear cylinder is installed on one side of the linear slide rail. The linear slide block is slidably installed on the linear slide rail and connected to the push rod of the linear cylinder. The linear cylinder's extension and retraction drive the linear slide block to slide on the linear slide rail. The slide block bracket is fixedly installed on the top of the linear slide block.

[0011] Furthermore, the distance between the two transfer grippers is the same as the distance between the positioning seat and the assembly turntable, and the distance between the assembly turntable and the unloading module.

[0012] Furthermore, the feeding vibratory feeder includes a feeding plate, a discharge port, a drive mechanism, and a discharge channel connecting the feeding plate and the discharge port.

[0013] Furthermore, the positioning seat is provided with a positioning groove corresponding to the zebra stripe at the position corresponding to the discharge port, and a clearance groove is provided on both opposite sides of the positioning groove. The width of the clearance groove is greater than the width of the transfer gripper of the transfer mechanism.

[0014] Furthermore, a gripper cylinder is provided between the two transfer grippers and the double gripper bracket to control the opening and closing of the transfer grippers.

[0015] Furthermore, a cable chain plate for cable chain installation is provided on a bracket on one side of the mobile module. One end of the cable chain is fixed to the double-claw bracket by a connecting fastener, so that the cable chain moves synchronously with the movement of the linear slide; the other end of the cable chain is fixed to the cable chain plate.

[0016] Furthermore, the rotating seat of the assembly turntable is a rotary cylinder, which is fixed to the bracket by a base plate. A mounting plate is fixed on the rotating seat, and two assembly seats are arranged opposite each other at both ends of the mounting plate. Each assembly seat includes a fixed slide rail, two sliding blocks slidably arranged on the fixed slide rail, and control grippers fixed together with the two sliding blocks. The mounting plate has a limiting plate for placing the zebra strip frame on one side corresponding to the control grippers. The limiting plate has a front limiting protrusion between the two control grippers. One end of the two control grippers is fixed to the sliding block, and the other end of one control gripper has a rear limiting block. The front limiting protrusion and the rear limiting block form a distance to limit the two ends of the zebra strip frame, so that the zebra strip frame is restricted between the front limiting protrusion and the rear limiting block.

[0017] With the above structure, this utility model's automatic loading and unloading device for LCD zebra strip frames can quickly and continuously complete the loading and unloading operations of LCD zebra strip frames. Compared with manual operation, it greatly shortens the loading and unloading time, improves production efficiency, and meets the needs of large-scale production.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0028] like Figures 1 to 6 As shown, this utility model discloses an automatic loading and unloading device for LCD zebra strip frames, which includes a support 1 and a loading vibratory plate 2, a positioning seat 3, an assembly turntable 4, a transfer mechanism 5, and an unloading module 6 disposed on the support 1.

[0029] The feeding vibratory feeder 2 includes a feeding plate 21, a discharge port 22, a driving mechanism, and a discharge channel 23 connecting the feeding plate 21 and the discharge port 22. The feeding plate 21 is used to place multiple zebra strip frames 10 for feeding. After the driving mechanism is driven, the feeding vibratory feeder 2 vibrates, and the zebra strip frames 10 can be transported from the discharge channel 23 to the discharge port 22.

[0030] like Figure 2As shown, the positioning seat 3 is located on one side of the discharge port 22. A positioning groove 31 is provided at the position of the positioning seat 3 corresponding to the discharge port 22, and clearance grooves 32 are provided on two opposite sides of the positioning groove 31. The zebra strip frame 10 flowing out of the discharge port 22 of the feeding vibrating plate 2 is pushed into the positioning groove 31 of the positioning seat 3 under the vibration of the driving mechanism, so that the position of the zebra strip frame 10 is limited on the positioning seat 3.

[0031] like Figure 3 and Figure 4 As shown, the transfer mechanism 5 includes a moving component, a sliding support 54, a lifting module 55, a double-jaw support 56, and transfer jaws 57. The positioning seat 3, the assembly turntable 4, and the unloading module 6 are arranged side by side at equal intervals. The moving component is movably disposed at one end of the positioning seat 3, the assembly turntable 4, and the unloading module 6. The sliding support 54 is connected to the moving component. The lifting module 55 is disposed on the sliding support 54. The double-jaw support 56 is fixedly disposed at the top of the lifting module 55 and can move up and down with the lifting module 55. The two transfer jaws 57 are spaced apart at both ends of the double-jaw support 56 facing the assembly turntable 4. The moving module drives the sliding support 54 and the lifting module 55, the double-jaw support 56, and the transfer jaws 57 on it to move between the positioning seat 3, the assembly turntable 4, and the unloading module 6, so that the two transfer jaws 57 can transfer between the positioning seat 3 and the assembly turntable 4 or between the assembly turntable 4 and the unloading module 6.

[0032] In this embodiment, the moving module includes a linear slide rail 51, a linear slide block 52, and a linear cylinder 53. The linear slide rail 51 is fixedly installed, the linear cylinder 53 is installed on one side of the linear slide rail 51, the linear slide block 52 is slidably installed on the linear slide rail 51, and is connected to the push rod 531 of the linear cylinder 53. The linear slide block 52 is driven to slide on the linear slide rail 51 by the extension and retraction of the linear cylinder 53. The slide block bracket 54 is fixedly installed on the top of the linear slide block 52.

[0033] A gripper cylinder 58 for controlling the opening and closing of the two transfer grippers 57 is provided between the two transfer grippers 57 and the double gripper bracket 56. In this embodiment, the distance between the two transfer grippers 57 is the same as the distance between the positioning seat 3 and the assembly turntable 4 and the distance between the assembly turntable 4 and the unloading module 6, so that the two transfer grippers 57 can simultaneously transfer the zebra strip frame 10 between the positioning seat 3 and the assembly turntable 4, or move between the assembly turntable 4 and the unloading module 6.

[0034] To ensure the safety and orderly operation of cables during the operation of the mobile module, cable management is carried out using cable carriers 59. A cable carrier plate 591 adapted for the installation of cable carriers 59 is installed on the bracket 1 on one side of the mobile module. One end of the cable carrier 59 is firmly fixed to the double-claw bracket 56 by a connecting fastener, so that the cable carrier 59 can move synchronously with the movement of the linear slide 52; the other end is fixed to the cable carrier plate 591 to ensure that the cable carrier 59 remains stable during the extension and retraction process.

[0035] like Figure 5 As shown, the assembly turntable 4 is spaced apart on one side of the positioning seat 3. The assembly turntable 4 has a rotating seat 41 and two assembly seats 42 for clamping or loosening the zebra strip frame 10. The assembly seats 42 are fixed on the rotating seat 41. In this embodiment, the rotating seat 41 is a rotary cylinder. The rotary cylinder is fixed on the bracket 1 through the base plate 411. A mounting plate 43 is fixed on the rotating seat 41. There are two assembly seats 42, which are arranged opposite to each other at both ends of the mounting plate 43. Each mounting base 42 includes a fixed slide rail 421, two sliding blocks 422 slidably mounted on the fixed slide rail 421, and control grippers 423 fixed together with the two sliding blocks 422. The mounting plate 43 is provided with a limiting plate 44 for placing the zebra strip frame 10 on one side corresponding to the control gripper 423. The limiting plate 44 is provided with a front limiting protrusion 441 between the two control grippers 423. One end of the two control grippers 423 is fixed on the sliding block 422, and the other end of one control gripper 423 is provided with a rear limiting block 45. The front limiting protrusion 441 and the rear limiting block 45 form a distance between the two ends of the zebra strip frame 10, so that the zebra strip frame 10 can be restricted between the front limiting protrusion 441 and the rear limiting block 45.

[0036] The feeding module 6 includes a feeding guide plate 61 and a feeding box 62. One end of the feeding guide plate 61 is installed on one side of the linear slide rail 51, and the other end is located on the feeding box 62. The feeding guide plate 61 is inclined so that the zebra strip frame 10 for assembly can slide into the feeding box 62.

[0037] The operation process of this utility model's automatic loading and unloading device for LCD zebra strip frames is as follows:

[0038] The zebra strip frame 10 is poured into the feeding tray 21 of the feeding vibratory plate 2; the drive mechanism is started, which drives the entire feeding vibratory plate 2 to vibrate. Under the action of vibration, the zebra strip frame 10 is conveyed from the discharge channel 23 to the discharge port 22, and then conveyed to the positioning slot 31 of the positioning seat 3.

[0039] The linear cylinder 53 of the transfer mechanism 5 extends, driving the linear slide 52 and its slide bracket 54, lifting module 55, double gripper bracket 56 and transfer gripper 57 to move towards one end of the positioning seat 3, so that one transfer gripper 57 is located on the positioning groove 31 of the positioning seat 3, and the other transfer gripper 57 is located on the assembly turntable 4. The lifting module 55 drives the double gripper bracket 56 and the two transfer grippers 57 to descend, and the gripper cylinder 58 controls the transfer gripper 57 to open to a distance greater than the zebra strip frame 10, so that the transfer gripper 57 enters the positioning seat 3 from the clearance groove 32 of the positioning seat 3, and then controls the transfer gripper 57 to clamp the zebra strip frame 10.

[0040] The lifting module 55 of the transfer mechanism 5 drives the double gripper bracket 56 and two transfer grippers 57 to rise, and the linear cylinder 53 retracts, causing the lifting module 55, the double gripper bracket 56 and the transfer grippers 57 to move to the other end. After retracting into place, the transfer gripper 57 that grips the zebra strip frame 10 is located on the assembly turntable 4, and the other transfer gripper 57 is located on the unloading guide plate 61 of the unloading module 6.

[0041] The lifting module 55 of the transfer mechanism 5 drives the double gripper bracket 56 and two transfer grippers 57 to descend, placing the gripped zebra strip frame 10 on the assembly seat 42 of the assembly turntable 4, and then clamping and fixing it by controlling the gripper 423.

[0042] The assembly turntable 4 rotates, swapping the positions of the assembly seat 42 with the zebra stripe frame 10 and the empty assembly seat 42. This allows the assembly seat 42 with the zebra stripe frame to assemble the zebra stripe. Simultaneously, the transfer mechanism 5 repeats the feeding action of the zebra stripe frame 10, so that while the assembly turntable 4 is assembling, the other assembly seat 42 on the assembly turntable 4 is also re-assembled with the zebra stripe frame 10.

[0043] The assembly turntable 4 rotates again, swapping the positions of the assembly seat 42 without zebra stripes and the assembly seat 42 with zebra stripes. One of the transfer grippers 57 of the transfer mechanism 5 picks up the zebra strip frame product with zebra stripes, while the other transfer gripper 57 simultaneously picks up an empty zebra strip frame 10 from the positioning seat 3. Then, the transfer mechanism 5 moves both transfer grippers 57 to one end of the unloading module 6, sending the assembled zebra strip frame into the unloading guide plate 61 of the unloading module 6, allowing the product to fall from the unloading guide plate 61 into the unloading box 62, completing the unloading of the product. At the same time, the other transfer gripper 57 places the unassembled zebra strip frame 10 into the assembly seat 42 of the assembly turntable 4, repeating the actions of picking up zebra strip frames 10, installing zebra stripes, and picking up the product, completing the automatic loading and unloading of zebra strip frames 10.

[0044] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
