Description

Technical Field

[0001] The utility model belongs to the field of automatic feeding equipment, and specifically relates to a feeding device for a mobile phone case inkjet device. Background Art

[0002] A tray is a common transportation and loading tool, which can realize the flexible operation of goods and is widely used in fields such as production, transportation, warehousing, and circulation. In traditional tray feeding mechanisms, most trays are presented as individual entities and are fed separately, unable to achieve stacked tray feeding. As a result, during the processing and production process, workers need to continuously place feeding trays into the feeding equipment.

[0003] The Chinese patent document "CN212333837U, a tray stacking and operating feeding device" includes a tray supply mechanism and a tray receiving mechanism arranged at intervals, and a tray operating mechanism for operating trays between the bottom of the tray supply mechanism and the bottom of the tray receiving mechanism. A feeding mechanism for picking up workpieces in the tray on the tray operating mechanism and transporting them to the outside is provided in the spaced space between the tray supply mechanism and the tray receiving mechanism. The tray operating mechanism includes parallel tracks, a tray operating seat slidably arranged on the parallel tracks, and a linear driving source for driving the tray operating seat to run on the parallel tracks. A limiting structure for fixing the tray is provided on the tray operating seat. The tray supply mechanism includes a supply stacking rack for stacking trays located at the top of the parallel tracks, and a stacking tray lifting part with lifting displacement for supporting the stacked trays is provided on the supply stacking rack. The tray receiving mechanism includes a receiving stacking rack for stacking trays located at the top of the parallel tracks, and a stacking part for releasing the stacked trays and stacking them on the tray operating seat and for lifting the stacked trays away from the tray operating seat.

[0004] The above structure fixes the tray by setting a limiting mechanism to prevent it from falling together with other trays and the lowermost tray, and uses a stacking tray lifting part to transport the lowermost tray, and transports the tray to the tray receiving mechanism through the tray operating mechanism. This structural design is complex, has high requirements for the limiting mechanism during tray operation to prevent other trays from operating together with the lowermost tray, and increases the manufacturing cost of the equipment.

Detailed implementation mode

[0031] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0032] Please refer to Figure 1-8 ;

[0033] A feeding device for a mobile phone case inkjet device, comprising a conveying bin 1 and an output bin 2. A conveying device 3 is provided in the conveying bin 1. The conveying device 3 is used to transport the loading trays. The trays can be stacked manually, eliminating the need for multiple tray transports and improving work efficiency. A lifting device 4 is provided on one side of the conveying device 3. A conveying device 5 is provided in the output bin 2. A lifting device 6 is provided on one side of the conveying device 5. A material taking device 7 is provided above the conveying device 3 for taking out the products to be inkjet on the trays. A tray transporting device 8 that shuttles between the two is provided between the conveying bin 1 and the output bin 2. The tray transporting device 8 is arranged at the lower end of the openings of the conveying bin and the output bin. The tray transporting device 8 includes a linear motor module 81. The linear motor module 81 is a commonly used linear motor module on the market. A moving slide 82 is installed on the moving end of the linear conveying motor. A lifting cylinder 83 is installed on the moving slide 82. A fixing plate 84 is provided on the lifting cylinder 83. The fixing plate 84 is driven to rise and fall by the lifting cylinder 83. A number of strip holes 85 are symmetrically provided on the fixing plate 84. A suction nozzle 86 is installed on the number of strip holes 85. The suction nozzle 86 is fixed in the strip hole 85 by using screws. The strip hole 85 is an oval hole. The suction nozzle 86 is fixed in the strip hole 85 by using upper and lower nuts. By loosening one of the nuts, the position of the suction nozzle 86 can be adjusted to achieve the purpose of adsorbing trays of different sizes. The initial position of the moving slide 82 is in the output bin 2 to avoid blocking the material taking device 7 from taking out the products to be inkjet on the trays. Since the fixing plate 84 does not need to rise too high, only the suction nozzle 86 needs to be higher than the adjacent side wall of the conveying bin 1 and the output bin 2 to avoid collisions. Therefore, only one lifting cylinder 83 is provided, with a simple structure, small occupied volume, and low manufacturing cost.

[0034] Specifically, place the product to be inkjet-printed on the tray, and then place multiple trays on the first conveying device 3 in a stacked manner. The first conveying device 3 starts to convey the trays to the first lifting device 4, and then the first lifting device 4 rises to lift the trays. After the trays are lifted in place, the material taking device 7 takes away the products to be inkjet-printed on the topmost material-carrying tray. After all the products to be inkjet-printed are taken out, the lifting cylinder 83 drives the fixed plate 84 to rise, and the linear motor module 81 controls the moving slide 82 to start moving until the first suction nozzle 86 is located above the tray. The lifting cylinder 83 drives the fixed plate 84 to descend until the first suction nozzle 86 fits the tray. After the first suction nozzle 86 adsorbs the tray, the lifting cylinder 83 drives the fixed plate 84 to rise to lift the tray. The moving slide 82 resets, the lifting cylinder 83 drives the fixed plate 84 to descend, and aligns the tray with the second lifting device 6. Cancel the adsorption effect of the first suction nozzle 86, and the tray can be placed on the second lifting device 6. The second lifting device 6 descends a certain distance. At this time, the first lifting device 4 rises a certain distance, and then repeat the above steps of taking out the products to be inkjet-printed and transporting the trays until all the trays on the first lifting device 4 are sucked onto the second lifting device 6. The second lifting device 6 starts to descend and places the trays completely on the second conveying device 5. The second conveying device 5 starts and sends out the trays, realizing the transportation of products and the operation of empty trays in the form of stacking single trays, reducing the requirement for the height of the device, making reasonable use of the internal space of the device, and having a simple structure.

[0035] In order to ensure that the moving slide 82 can slide smoothly, in this embodiment, a first moving guide rail 87 is provided on one side of the linear motor module 81. A moving slider 88 is provided on the first moving guide rail 87, and the moving slider 88 is fixedly connected to the bottom of the moving slide 82. Through the cooperation of the linear motor module 81, the first moving guide rail 87 and the moving slider 88, both sides of the moving slide 82 are supported to ensure that the moving slide 82 will not tilt or shift in position during movement.

[0036] In this embodiment, the first conveying device 3 includes a first support frame 31 for installing the first driving motor 32. Two first driving rollers 33 are symmetrically installed on both sides of the first support frame 31. A first conveyor belt 34 is driven and connected by the two first driving rollers 33 on each side. A first transmission roller 35 is driven and connected between the two first driving rollers 33 corresponding to the same end of the first support frame 31, so that the two first driving rollers 33 on both sides can rotate synchronously, and thus the two first conveyor belts 34 can also move synchronously. The first transmission roller 35 extends to the outer end of the first driving roller 33 and is fixedly connected with a first driven wheel 37. The first driven wheel 37 is driven and connected with a first driving wheel 36 through a belt. The first driving wheel 36 is installed at the output end of the first driving motor 32. Specifically, when the first driving motor 32 is started, it drives the first driving wheel 36 to rotate. When the first driving wheel 36 rotates, it drives the first driven wheel 37 to rotate through the belt. When the first driven wheel 37 rotates, it drives the first transmission roller 35 to rotate together. The first transmission roller 35 causes the two first driving rollers 33 to rotate synchronously, so that the two first conveyor belts 34 move synchronously, avoiding the asynchronous movement of the first conveyor belt and resulting in the offset of the tray during transportation and the tray being separated from the first conveyor belt 34.

[0037] In this embodiment, the first lifting device 4 includes a first mounting plate 41 for installing the second driving motor 42. Two first screw bases 43 are fixedly installed on the first mounting plate 41. A first screw rod 44 is driven and connected between the two first screw bases 43. The first screw rod 44 is stably driven in the device through the two first screw bases 43 at both ends. A second driven wheel 46 is fixedly installed at the lower end of the first screw rod 44. The second driven wheel 46 is driven and connected with a second driving wheel 45 through a belt. The second driving wheel 45 is installed at the output end of the second driving motor 42. A first nut seat 47 is threadedly connected to the first screw rod 44. A first tray rack 48 is fixedly installed on the first nut seat 47. The thread on the first screw rod 44 and the first nut seat 47 on the first tray rack 48 form a threaded drive to realize the linear lifting movement of the tray rack. Specifically, when the second driving motor 42 is started, it drives the second driving wheel 45 to rotate. The second driving wheel 45 drives the second driven wheel 46 to rotate through the belt. When the second driven wheel 46 rotates, it drives the first screw rod 44 to rotate. Since the first nut seat 47 is fixedly connected to the first tray rack 48 that needs to be lifted, the rotation of the first screw rod 44 will be converted into the linear movement of the first nut seat 47 and the first tray rack 48, thus realizing the lifting function of the first tray rack 48.

[0038] In order to ensure that the first tray rack 48 can slide smoothly, two first sliding guide rails 411 are symmetrically installed on the first mounting plate 41. A first slider 412 that is slidably matched with each of the two first sliding guide rails 411 is installed on each of the two first sliding guide rails 411. The first slider 412 is fixedly connected with the first tray rack 48.

[0039] In this embodiment, the second conveying device 5 includes a second support frame 51 for mounting the third driving motor 52. Two driving rollers II 53 are symmetrically mounted on both sides of the second support frame 51. A conveyor belt II 54 is drivenly connected between the two driving rollers II 53 on each side. A second driving roller II 55 is drivenly connected between the two driving rollers II 53 corresponding to the same end of the second support frame 51. The second driving roller II 55 extends outside the driving roller II 53 and is fixedly connected with a third driven wheel 57. A second belt drivesly connects a third driving wheel 56 on one side of the third driven wheel 57. The third driving wheel 56 is mounted on the output end of the third driving motor 52. The structure of the second conveying device 5 is the same as that of the first conveying device 3. The third driving motor 52 of the second conveying device 5 rotates in the reverse direction of the first driving motor 32 of the first conveying device 3, so as to be able to send out the tray.

[0040] In this embodiment, the second lifting device 6 includes a second mounting plate 61 for mounting the fourth driving motor 62. Two screw rod seats II 63 are fixedly mounted on the second mounting plate 61. A screw rod II 64 is drivenly connected between the two screw rod seats II 63. The lower end of the screw rod II 64 is fixedly mounted with a fourth driven wheel 66. The fourth driven wheel 66 is drivesly connected with a fourth driving wheel 65 through a belt. The fourth driving wheel 65 is mounted on the output end of the fourth driving motor 62. A nut seat II 67 is threadedly connected to the screw rod II 64. A tray rack II 68 is fixedly mounted on the nut seat II 67. The structure and operation mode of the second lifting device 6 refer to the first lifting device 4, and will not be described in detail here.

[0041] To ensure that the tray rack II 68 can slide smoothly, two sliding guide rails II 611 are symmetrically mounted on the second mounting plate 61. A second slider 612 that is slidably engaged with the sliding guide rail II 611 is mounted on each of the two sliding guide rails II 611. The second slider 612 is fixedly connected with the tray rack II 68.

[0042] In this embodiment, the material taking device 7 includes a third support frame 71. A second moving guide rail 72 and a first sliding table 721 sliding on the second moving guide rail 72 are installed on the third support frame 71. The first sliding table 721 is driven by a fifth driving motor 722 to slide on the second moving guide rail 72. A third moving guide rail 73 and a second sliding table 731 sliding on the third moving guide rail 73 are installed on one side of the first sliding table 721. The second sliding table 731 is driven by a sixth driving motor 732 to slide on the third moving guide rail 73. A fourth moving guide rail 74 and a third sliding table 741 sliding on the fourth moving guide rail 74 are installed on the second sliding table 731. The third sliding table 741 is driven by a seventh driving motor 742 to slide on the fourth moving guide rail 74. A fixing frame 743 is vertically installed on the third sliding table 741. A second suction nozzle 744 is provided at the lower end of the fixing frame 743. The fixing frame 743 has a structure similar to an "L" shape. The second suction nozzle 744 is arranged in the horizontally extending part of the fixing frame 743. Through the cooperation of the second moving guide rail 72 and the third moving guide rail 73, the second suction nozzle 744 can be aligned with the products to be inkjet-printed at different positions on the tray. Then, the fourth moving guide rail 74 controls the third sliding table 741 to perform a descending action, so that the second suction nozzle 744 can contact the products to be inkjet-printed on the tray and adsorb them. The third sliding table 741 rises, and then the products to be inkjet-printed are placed on the subsequent processing equipment.
