Description

Technical Field

[0001] This utility model relates to the field of cassette polishing, and in particular to a fully automatic polishing feeding device. Background Technology

[0002] The SIM card of a smartphone is installed inside the side of the phone frame via a card tray. During the processing of the card tray, a preliminary card tray with a card holder and a card cap is first formed using a high-precision stamping die. This preliminary card tray is then inserted into a card tray tray tray with several insertion holes. After several trays are filled with preliminary card trays, they are transferred to the post-processing stage. The post-processing stage includes a series of steps such as CNC machining, sandblasting, oxidation, wire drawing, and polishing. However, all these processes require the use of card tray fixtures to fix the card trays. Therefore, before each process, the card trays on the tray tray must be inserted one by one into the corresponding card tray fixture. Currently, there are feeding devices on the market for card tray turntables. Since the card tray fixtures for CNC machining, sandblasting, oxidation, and wire drawing in the post-processing stage are all square in structure and arranged in the same way as the card tray trays, the feeding device only has a suction nozzle with horizontal and vertical movement. The suction nozzle picks up all the card trays in a row from the tray tray and places them into the card tray fixture. However, the polishing caddy fixture used for polishing is a circular disc with four spaced-apart caddy placement areas. Each caddy placement area has several rows of placement slots for caddies, and each row of placement slots consists of several spaced-apart slots. Therefore, traditional feeding equipment cannot be directly used for feeding the polishing caddy fixture in the polishing process. Currently, feeding the polishing caddy fixture in the polishing process is done manually. Manual operation is prone to problems such as missed placements, improper placement, and incorrect placement orientation, resulting in a low processing yield.

[0003] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content

The transfer plate is provided on the upper sliding plate, and the rear end of the upper sliding plate is connected to the top surface of the rotating belt. The suction device has a suction nozzle that is suspended above the parking area. The suction nozzle is installed on the mounting plate in a manner that allows it to lift the card holder on the lifting and placing plate by moving up and down and to slide to the left to insert the card holder into the transfer plate.

[0011] A lower sliding plate is slidably mounted on the lower base plate between the front and rear side plates, and is located below the upper sliding plate. An opening is provided on the rear side plate within the right end range of the rotating belt. The rear end of the lower sliding plate extends out of the opening and connects with the inner bottom surface of the rotating belt. The lower sliding plate and the upper sliding plate are staggered and spaced apart. The lower sliding plate is provided with the aforementioned transfer plate, and the transfer plate on the lower sliding plate is located below the upper sliding plate.

[0012] The mounting plate has a drive motor extending in the left-right direction at the top left end, with the drive motor facing left and a rotating rod connected to the conveying end of the drive motor. The mounting plate has two crossbeams with open tops and hollow structures, located at the top left end of the mounting plate. The two crossbeams are spaced apart in the left-right direction and extend in the front-back direction. The drive motor is located outside the front end of the right crossbeam, and the rotating rod passes through the two crossbeams. A drive sprocket is fitted inside the crossbeam on the rotating rod, and a driven sprocket is rotatably mounted at the rear end of the two crossbeams.

[0015] This fully automatic polishing feeding equipment, in its application, involves stacking trays one on top of the other in the tray placement area. A clamping device suspends the trays above the bottommost tray above it. A pushing device pushes the bottommost tray out of the tray placement area and into the lifting placement plate. A suction device then picks up the trays from the bottom tray and transfers them to a transfer plate. Once all the trays are transferred to the transfer plate, the lifting placement plate lowers, placing the trays on two conveyor belts. The two conveyor belts then output the trays from the machine frame. After the trays are removed from the lifting placement plate, the lifting placement plate rises again, and the pushing device continues to transport the trays from the bottommost tray in the placement area. The card tray is transferred to the lifting and placing plate for the suction device to transfer card trays. After the transfer tray is full of card trays, the polishing card tray fixture is placed on the top input end of the two placement conveyor bars by the robot arm. The polishing card tray fixture is transported to the positioning collar range. The top plate device is activated to lift the polishing card tray fixture upwards, so that the polishing card tray fixture is limited within the positioning collar. The card tray suction cup device inserts the card trays on the transfer tray into the card tray placement area of ​​the polishing card tray fixture. After the polishing card tray fixture is full of card trays, the top plate device is reset, and the polishing card tray fixture falls onto the top surface of the two placement conveyor bars. The two placement conveyor bars continue to transport the polishing card tray fixture to the top conveyor end of the two placement conveyor bars. Finally, the polishing card tray fixture is rotated out of the frame by the robot arm. Compared with existing technologies, the loading of polishing cassette fixtures is all automated, which improves production efficiency, reduces labor costs, and is less prone to problems such as missing, improper placement, and incorrect placement direction, thus improving the yield rate. In addition, the loading mechanism, transfer mechanism and unloading mechanism are set up in separate areas, which facilitates the disassembly and installation of the entire equipment.

A compression spring (not shown in the figure) is provided between the upper end of the limiting block 1411 and the bottom of the strip-shaped groove. On the opposite sides of the two conveyor belts 13, multiple fixing blocks 141 and limiting blocks 1411 are provided. The right end of the lower plate 14, located inside the lower end of the tray, is equipped with a pushing device that pushes the tray out of the top surface of the limiting block 1411 and onto the top surface of the fixing block 141. Specifically, the bottom surface of the lower plate 14, located between the two conveyor belts 13, is equipped with a push-out cylinder (not shown in the figure). The push-out cylinder is upward-facing and connected to a push-out plate located below the tray. Figure 3 As shown, during application, the card tray is driven by the lifting and placing plate 12, which moves downward and stacks on the left end of the conveyor belt 13. The card tray is then transported to the right end of the conveyor belt 13 and falls into the horn space. The lifting and placing plate 12 moves upward and resets, the push-out cylinder is activated, and the push-out plate moves upward, pushing the card tray upward. Under the action of the compression spring, the distance between the horn space between the two fixing blocks 141 increases, causing the card tray to detach from the horn space until it finally stacks on the top surface of the fixing block 141. The compression spring resets, and the distance between the horn space between the two fixing blocks 141 decreases.

[0031] The transfer mechanism has a transfer tray 51 on which a plurality of card trays are inserted and a suction device 52 that picks up the card trays in the parking area and transfers them to the transfer tray 51.

The two ends of the suction strip 72 are connected to the two corresponding opposing adjusting guide blocks 715. The bottom surface of the suction strip 72 is recessed with a number of insertion slots into which the side plates of the card tray extend. The number of insertion slots corresponds to the card slots on the transfer tray, that is, there are ten insertion slots. The card tray suction and release frame 71 is mounted on the mounting plate in a manner that allows it to rotate circumferentially, move up and down, move left and right, and move back and forth. That is, the card tray suction and release frame 71 is connected to the output end of a multi-axis moving robot. The way the multi-axis moving robot moves the card tray suction and release frame 71 up and down, left and right, and back and forth, as well as the way the suction strip uses vacuum to lift the card tray, are all technologies known to those skilled in the art. In application, the robotic arm controls the card tray suction and release frame 71 to move above the transfer plate 51 and sucks the card trays into the corresponding slots one by one. Then, the card trays are inserted into the polishing card tray fixture in the positioning sleeve 61 one by one.

[0035] The frame has a front loading structure capable of placing the polishing tray fixture on the front end of the placement conveyor bar 62 and a rear unloading mechanism capable of transferring the polishing tray fixture conveyed to the rear end of the placement conveyor bar out of the mounting plate 1. The front loading structure is mounted on the mounting plate 1 in a manner that allows it to move up and down and translate forward and backward to transport the polishing tray fixture outside the frame to the front end of the placement conveyor bar 62. The rear unloading mechanism is mounted on the mounting plate 1 in a manner that allows it to translate left and right and move up and down to transfer the polishing tray fixture conveyed to the rear end of the top surface of the placement conveyor bar 62 out of the mounting plate 1. Figure 1 As shown, specifically, both the front loading structure and the rear unloading mechanism have clamping claws 81, cylinders 82, and clamping mounting plates 83. The clamping claws 81 have two opposing clamping limit blocks that can move relative to or away from each other. The clamping mounting plates 83 are horizontally positioned. On the front loading structure, the clamping mounting plate 83 is horizontally positioned along the front-to-back direction on the left side of the front end of the mounting plate 1 and falls within the range of the two placement conveyor bars. On the rear unloading structure, the clamping mounting plate 83 is horizontally positioned along the left-to-right direction on the left side of the rear end of the mounting plate 1. The cylinder 82 is a double-rod cylinder, mounted on the bottom surface of the clamping mounting plate 83 and horizontally positioned along the horizontal direction of the clamping mounting plate 83. The clamping limit blocks... The two clamping blocks are respectively erected on the two output ends of the double-rod cylinder, and the two clamping limit blocks have a protruding clamping block 811 on the opposite side. The two clamping blocks 811 have a recessed groove that matches the shape of the polishing card holder fixture. The polishing card holder fixture is a circular structure, and the groove is a corresponding arc groove. The clamping mounting plate 83 of the front loading structure is installed on the front left side of the mounting plate 11 in a way that can move back and forth and lift up and down. The clamping mounting plate 83 of the rear unloading structure is installed on the rear left side of the mounting plate 11 in a way that can move left and right and lift up and down. The lateral movement and vertical lifting of the clamping mounting plate are technologies known to those skilled in the art and will not be described in detail here. In application, the front loading structure moves downward, and the polishing card holder fixture falls between the two clamping blocks of the front loading structure. The clamping cylinder of the front loading structure is activated, and the two clamping blocks 811 move relative to each other. The front loading structure clamps the polishing card holder fixture, moves upward, and then moves backward, conveying the polishing card holder fixture to the front end of the two placement conveyor bars. The two placement conveyor bars are conveyed downward. When the polishing card holder fixture is conveyed to the rear end of the two placement conveyor bars, the rear unloading structure moves downward, causing the polishing card holder fixture located at the rear end of the two placement conveyor bars to fall between the two clamping blocks of the rear unloading structure. The clamping cylinder of the rear unloading structure is activated, and the rear unloading structure clamps the polishing card holder fixture. The rear unloading structure moves upward and then moves to the left, transferring the polishing card holder fixture off the two placement conveyor bars.

[0036] In this fully automatic polishing feeding device, the trays are stacked one on top of the other in the placement frame 111. The lifting and clamping cylinder 24 is activated, and the two clamping blocks move to the limiting groove range of the second-to-last tray from the bottom. The clamping cylinder is then activated, and the two clamping blocks 21 move relative to each other, causing the limiting protrusions 211 on the two clamping blocks to extend into the corresponding limiting grooves of the trays. The two clamping blocks 21 then move upwards, suspending the trays above the bottom tray in mid-air. Above the lower card tray, the push cylinder is activated, driving the push block 32 to push the lowest card tray to the left. At this time, the card tray is pushed out of the discharge port and falls into the lifting placement plate. The suction device 52 sucks the card tray onto the transfer plate 51 located at the right end of the transfer frame. After all the card trays on the card tray have been transferred to the transfer plate 51, the lifting placement plate 51 moves down, and the card tray is placed on the left end of the two conveyor belts 13. The tray is output to the right end of the two conveyor belts and then output. After the tray moves out of the lifting placement plate 2, the lifting placement plate 51 moves upward, and the push block 32 continues to transport the trays at the bottom of the placement frame 111 to the lifting placement plate 51 for the suction device to transfer the trays. After the transfer plate 51 is full of trays, the transfer plate is transported to the left end of the transfer plate 51. The polishing tray fixture is placed on the top front end of the two placement conveyor strips by the robot arm. The polishing tray fixture is then transported... Once the polishing tray is placed within the limiting groove, the top plate device activates, positioning the polishing tray fixture within the positioning ring 61. The tray suction cup device then inserts the trays from the transfer plate 51 into the corresponding tray placement area of ​​the polishing tray fixture. After the polishing tray fixture is fully filled with trays, the top plate device resets, and the polishing tray fixture falls onto the top surface of the two placement conveyor bars. The two placement conveyor bars continue to transport the polishing tray fixture to the rear end of the top surface of the two placement conveyor bars. Finally, a robotic arm rotates the polishing tray fixture out of the frame. Compared with existing technologies, the loading of the polishing tray fixture is entirely automated, thereby improving production efficiency, reducing labor costs, and reducing the likelihood of missed placement, improper placement, or incorrect placement direction, thus improving the yield rate. Furthermore, the loading mechanism, transfer mechanism, and unloading mechanism are separated, facilitating the disassembly and installation of the entire equipment.

[0037] In this utility model, the preferred feature is that, Figure 8As shown, a lower sliding plate 1522 is slidably mounted on the lower base plate 151 between the front side plate 152 and the rear side plate 153, and is located below the upper sliding plate 1521.

The transfer disk 51 on the lower sliding plate 1522 is located below the upper sliding plate 1521, and the lower sliding plate 1522 and the upper sliding plate 1521 are staggered and spaced apart to the left and right. In application, when the upper sliding plate 1521 is at the left end and the lower sliding plate 1522 is at the right end, and when the upper sliding plate 1521 is at the right end and the lower sliding plate 1522 is at the left end, the transfer plate at the right end receives the card trays transferred from the parking area, and the transfer plate at the left end transfers the card trays to the polishing card tray fixture through the card tray suction and release device. After the card trays on the transfer plate at the left end are transferred, they are transported to the right end, and the transfer plate at the right end is also filled with card trays and transported to the left end. The alternating operation of the two transfer plates can improve the card tray transfer efficiency.

[0038] In this utility model, the preferred feature is that, Figure 3 As shown, the top surface of the upper top plate 11 is provided with a limiting cylinder 91, a limiting strip 92, a guide strip 93, and a top plate cylinder 94 on the front, left, and rear sides of the material outlet, respectively. The limiting cylinder 91 extends in the front-rear direction, and its output end faces rearward and is connected to a limiting plate 911. The rear side of the limiting plate 911 is flush with the front inner wall of the material outlet. The middle of the rear side of the limiting plate 911 protrudes rearward and extends in the left-right direction, and can overlap the front limiting protrusion on the front end of the top surface of the tray. The right side of the limiting strip 92 is flush with the left inner wall of the material outlet, and the upper end of the limiting strip 92 protrudes to the right and can overlap the left end of the top surface of the tray. The front of the guide strip 93... The side is flush with the rear inner wall of the discharge port. The lifting and placing plate 12 has a top plate opening that runs vertically through it. The top plate cylinder 94 is located on the top surface of the left end of the lower plate 14, and the top surface of the top plate cylinder 94 is lower than the top surface of the two placement conveyor bars 13. In application, when the card tray is conveyed to the left onto the lifting and placing plate, it abuts against the limiting bar 92. The card tray is in place and is limited by the left limiting protrusion. The limiting cylinder 91 is activated, which drives the front limiting protrusion to press against the card tray and simultaneously pushes the card tray backward against the backing bar 93. Then the top plate cylinder is activated to push the card tray upward, so that the card tray can be in the predetermined position after being transferred to the lifting and placing plate 12, which facilitates the precise suction of the suction device.
