Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of processing of decorative diamonds, and particularly relates to a decorative diamond paint spraying system capable of automatically feeding and discharging. BACKGROUND

[0002] A crystal (rhinestone) is a kind of accessory part obtained by cutting a man-made crystal glass into a diamond facet, and the material is relatively economical and has a dazzling feeling like a diamond in visual effect. In application, the crystal is generally embedded in a claw chain in advance, and then tin soldering is performed to form a predetermined shape, and then an electroplating process is performed to form a high-grade accessory. In the tin soldering process, the crystal protective paint will experience a high temperature higher than the tin melting point. Therefore, the prior art sprays paint on part of the surface of the crystal. Once the protective paint is damaged at a certain link in the production of the accessory, the silver plating layer will be damaged, the light reflection effect cannot be achieved, and the accessory is scrapped.

[0003] For example, patent No. CN202020674621.9 discloses a paint spraying system for crystal silver layer protective paint, which comprises a ring-shaped conveying belt and a feeding section, a silver baking heating section, a silver baking cooling section, a paint spraying section, a drying section, a paint spraying cooling section and a discharging section arranged in sequence and connected end to end on the ring-shaped conveying belt. The ring-shaped conveying belt is a track-shaped chain conveying structure. The discharging section, the feeding section and the silver baking heating section are sequentially located on one straight section of the ring-shaped conveying belt. The silver baking cooling section is located on one circular arc section of the ring-shaped conveying belt. The paint spraying section and the drying section are sequentially located on the other straight section of the ring-shaped conveying belt. The paint spraying cooling section is located on the other circular arc section of the ring-shaped conveying belt. The silver baking heating section comprises a first drying chamber through which the ring-shaped conveying belt passes. The drying section comprises a second drying chamber through which the ring-shaped conveying belt passes. The paint spraying section comprises at least one paint spraying chamber through which the ring-shaped conveying belt passes for spraying base paint and at least one paint spraying chamber through which the ring-shaped conveying belt passes for spraying surface paint. The silver baking cooling section comprises a blower and a spray pipe arranged along the conveying direction of the ring-shaped conveying belt and located above the ring-shaped conveying belt. One end of the spray pipe is closed, the other end is connected with the blower, and the lower side is uniformly provided with a plurality of spray holes. The paint spraying cooling section comprises a plurality of cooling fans arranged along the conveying direction of the ring-shaped conveying belt and located directly above the ring-shaped conveying belt. The cooling fans blow air downward. Referring to the content of paragraph 20 of the patent specification, "wherein the feeding section and the discharging section are manually placed and taken out by workers from the suction disc support".

[0004] In the existing technology, manual loading and unloading are very labor-intensive. One blister pack needs to be put in or taken out every 2 seconds (at a slow speed, the actual production speed is even faster). About 15,000 blister packs need to be processed in a day. If you are not careful, you may miss some. Usually, two operators are set up for each loading and unloading section to reduce labor intensity and avoid omissions. This means that four people are needed for loading and unloading alone, which is expensive. Utility Model Content

The annular conveyor belt 1 includes multiple circular supports 11 arranged at equal intervals. In the feeding section 2 and the unloading section 3, the circular supports 11 do not rotate; therefore, there are no friction belts in the feeding section 2 and the unloading section 3 to drive the rotation of the circular supports 11. For details on the structure of the annular conveyor belt 1, please refer to the descriptions in application numbers CN202020078287.0 or CN202020674623.8. A feeding device 4 and an unloading device 5 are respectively provided next to the feeding section 2 and the unloading section 3. The feeding device 4 and the unloading device 5 are located on the outer side of the corresponding circular support 11 of the annular conveyor belt 1 (in this patent, the side away from the annular conveyor belt 1 is defined as the outer side), and each includes a blister storage structure 6, a lifting structure 7, and a transfer structure 8. The blister tray storage structure 6 is used to store blister trays, and the lifting structure 7 is used to keep the top of the blister tray stack 63 at the same height at all times. The transfer structure 8 is used to transfer the blister trays between the circular support 11 and the blister tray stack 63.

[0033] Among them, see Figures 3-5In this embodiment, the blister tray storage structure 6 includes a base, a blister tray storage rack 61 rotatably mounted on the base (via a vertically mounted pivot), an indexing motor on the base, and multiple blister tray stacking areas 62 on the blister tray storage rack 61. The indexing motor drives the blister tray storage rack 61 to rotate in an indexing manner; the multiple blister tray stacking areas 62 are evenly distributed around the pivot and correspond to the indexing angle. The blister tray storage rack 61 is horizontally positioned and is a disc structure (specifically a disc structure in this embodiment), a regular polygon structure, or a cross shape, etc., located outside the column 81 (left or right side). The inner end of the blister tray stacking area 62 is arranged side by side with the corresponding circular bracket 11 of the feeding section 2 or the unloading section 3. A circular tray that matches the size of the blister tray is placed on the blister tray stacking area 62, and multiple guide rods 64 are evenly distributed around the tray and the blister tray on the blister tray stacking area 62. The guide rods 64 are vertically positioned and are specifically circular rods. Multiple blister packs are stacked one on top of the other on a tray and within the stacking area enclosed by multiple guide rods 64, forming a blister pack stack 63. The top of the blister pack stack 63 is flush with the circular support 11. The top of the blister pack stack 63 is located above the guide rods 64 to facilitate quick removal of the blister packs, and the suction cups 35 can move upwards to above the guide rods 64. The structure of the blister pack storage structure 6 can be found in the descriptions of applications CN202011480429.7, CN202020078288.5, or CN202020673697.X. The feeding device 4 and the unloading device 5 can share the same base.

[0034] Among them, see Figures 3-5The lifting structure 7 is located below the blister tray stack 63, and it can lift the blister tray stack 63 stepwise to keep the top of the blister tray stack 63 at the same height. The lifting structure 7 is located below the corresponding tray to allow the blister tray stack 63 to move up and down. Specifically, the lifting structure 7 includes a vertically arranged lifting frame 71, a tray 72 on the lifting frame 71 that can move up and down, and a stepping drive mechanism between the lifting frame 71 and the tray 72. The tray 72 can move up and down on the lifting frame 71, and the stepping drive mechanism is used to drive the tray 72 to move up and down step by step. The lifting frame 71 is located on the outside of the column 81 (left or right side). The tray 72 is located directly below the inner end of the blister tray stacking area 62, below the tray, and is arranged radially along the blister tray storage rack 61 and in the left-right direction. Each blister tray stacking area 62 has a notch for the tray 72 to pass through upwards; the notch is radially arranged along the blister tray storage rack 61 and is specifically a rectangular notch. After the tray 72 passes through the notch upwards, it lifts the stack of blister trays 63 upwards. Each time the blister tray storage rack 61 rotates by a division angle (e.g., 90°), one blister tray stacking area 62 is rotated to be directly above the tray 72, and the tray 72 passes through the notch upwards and rises step by step so that the top of the stack of blister trays 63 is always at the same height. When all the blister trays on the tray are removed, the tray 72 moves downwards to be directly below the blister tray stacking area 62, and the blister tray storage rack 61 rotates again by division. Furthermore, the center of the tray has a positioning hole in the vertical direction, and the upper side of the tray 72, directly opposite the positioning hole, has a positioning post in the vertical direction that matches the size of the positioning hole. Both the positioning hole and the positioning post are circular, and the upper end of the positioning post is a pointed tip (with a chamfered outer edge). When the pallet 72 lifts the pallet, the positioning pin can be inserted into the positioning hole to ensure stable lifting. When the positioning pin is inserted into the positioning hole, the upper side of the positioning pin is flush with or lower than the upper side of the pallet. The structure of the lifting structure 7 can be found in the description of application number CN202020078288.5.

[0035] Among them, see Figures 1-2 The transfer structure 8 includes a column 81, a rotating arm 82 rotatably mounted on the column 81, and two robotic arms 83 at both ends of the rotating arm 82. The column 81 is vertically positioned at the midpoint between the blister tray storage structure 6 and the circular conveyor belt 1. The lifting structure 7 is located on the side of the column 81 closest to the blister tray storage structure 6 (the outer side, specifically the left or right side). The rotating arm 82 is positioned horizontally, with its midpoint rotatably mounted on the column 81, and can rotate 180° in increments (clockwise or counterclockwise, or 180° back and forth). The two robotic arms 83 are located directly above the inner end of the blister tray stacking area 62 and the corresponding circular support 11, respectively, and move up and down synchronously (i.e., the two lifting cylinders 33 are driven synchronously). The rotating arms 82 of the loading device 4 and the unloading device 5 must not interfere with each other during rotation.

[0036] Among them, seeFigure 6 The robotic arm 83 includes a support 31, a lifting slide plate 32, a lifting cylinder 33, a buffer slide plate 34, a suction cup 35, a vacuum port, a buffer pad, a negative pressure port 36, a steel wire telescopic hose 37, and at least one air inlet. The support 31 is vertically positioned at the end of the rotating arm 82 and is specifically a rectangular plate. The lifting slide plate 32 is slidably positioned on the lower left or right side of the support 31, and can move up and down; it is vertically positioned. The lifting cylinder 33 is vertically positioned between the support 31 and the lifting slide plate 32, and is used to drive the lifting slide plate 32 to move up and down. The buffer slide plate 34 is slidably positioned on the left or right side of the lifting slide plate 32, and can move up and down; it is vertically positioned. The suction cup 35 is horizontally positioned and fixed to the bottom of the buffer slide plate 34; it is specifically a disc that mates with a blister pack and is used to pick up the blister pack. The vacuum port is located on the upper side of the suction cup 35, at the center of the suction cup 35, and is vertically positioned. A buffer pad is located on the underside of the suction cup 35. A negative pressure interface 36 is located on the top of the support 31, directly above the vacuum interface, and is vertically oriented. It is connected to the vacuum structure via a pipe with a valve. A steel wire telescopic hose 37 is vertically oriented, positioned between the negative pressure interface 36 and the vacuum interface, and is located on the left and right sides of the support 31, respectively, along with the lifting slide plate 32. An air blowing port is located on the suction cup 35, next to the vacuum interface, and is connected to the compressed air supply structure via a pipe with a valve. The suction cup 35 moves downwards to the upper side of the corresponding blister tray, and moves upwards to the upper side of the circular bracket 11 or the blister tray stacking area 62. The structure of the robotic arm 83 can be found in the descriptions of applications CN202011480429.7 or CN 202020673697.X.

[0037] Specifically, when the lifting cylinder 33 extends, the suction cup 35 presses against the blister pack on the circular bracket 11 or against the top of the blister pack 63. When the lifting cylinder 33 retracts, the suction cup 35 moves upward above the anti-fall support 12 or guide rod 64. When picking up the blister pack, the vacuum port draws a vacuum (controlled by a corresponding valve). When outputting the blister pack, the air outlet blows air (controlled by a corresponding valve).

[0038] Among them, see Figure 7 In this embodiment of the invention, the circular bracket 11 is a horizontally arranged mesh structure with a diameter larger than that of the blister pack. Multiple (4-12) anti-falling uprights 12 are evenly distributed on its upper outer edge. The anti-falling uprights 12 are vertically arranged, are round rods, and their upper ends are flush with the upper ends of the guide rods 64. The suction cup 35 can move upwards to above the anti-falling uprights 12. The structure of the circular bracket 11 can be found in the descriptions of applications CN202020078287.0 or CN 202020674623.8.

[0039] Example 2

[0040] Example 2 provides an automatic rhinestone spraying system with automatic loading and unloading capabilities. Its structure is basically the same as that of Example 1, except that the diameter of the circular support 11 in this example is 1-3 cm larger than the diameter of the blister pack (larger than the prior art (0.5-2.0 cm), allowing the robotic arm 83 more room to maneuver and preventing the blister pack from colliding with the anti-falling pole 12). The anti-falling pole 12 is vertically positioned with a height of 1.5-2.5 cm (smaller than the prior art (2-4 cm)) to reduce the travel distance of the suction cup 35 and increase speed. This also allows the suction cup 35 to quickly move away from the circular support 11, preventing the blister pack from colliding with the anti-falling pole 12.

[0041] Example 3

[0042] Example 3 provides an automatic loading and unloading rhinestone spraying system, whose structure is basically the same as that of Example 1, except that: in this example, the blister tray storage rack 61 is provided with four blister tray stacking areas 62, with an indexing rotation angle of 90°.

Two blister tray stacking areas 62 are arranged side by side, and the other two blister tray stacking areas 62 (one of which is located directly below the corresponding robot arm 83) are arranged side by side. Each blister tray stacking area 62 is provided with four guide rods 64, which are located on the same circle concentric with the tray. The diameter of the circle formed by the four guide rods 64 is 1-2 cm larger than the diameter of the blister tray, and the diameter of the tray is smaller than the diameter of the circle formed by the four guide rods 64, and the tray is coaxial with the blister tray.

[0043] Example 4

[0044] Example 4 provides a rhinestone spraying system capable of automatic feeding and unloading. Its structure is basically the same as that of Example 1, except that: in this example, the annular conveyor belt 1 is equipped with an operating room, and the feeding section 2, unloading section 3, feeding device 4, and unloading device 5 are all located within the operating room, avoiding external interference and reducing noise. Specifically, the operating room is a rectangular chamber arranged along the front-to-back direction with a door on its outer side.
