Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to an automatic feeding device for a positioner feeding machine. Background Technology

[0002] During the production of locators (such as GPS positioning modules), it is necessary to perform tests on current, resistance, and other related parameters. After the tests are completed, the locators need to be unloaded, that is, transferred from the test carrier to the material tray. Currently, some companies use robotic arms for automatic transfer and unloading. However, the robotic arms have a simple structure, and the positions of the multiple transfer suction cups on the robotic arms are fixed. The spacing between the acupoints on the material tray that support the products is different from the spacing between the acupoints on the carrier. This requires the configuration of a variable-pitch platform and two sets of robotic arms (the transfer suction cups on the two sets of robotic arms have different spacing). One robotic arm is used to transfer the products from the carrier to the variable-pitch platform, which then adjusts the pitch. The other set of robotic arms then transfers the adjusted products to the material tray. This operation is complex and costly. At the same time, the common practice is to manually move the material tray to the unloading position, which results in high labor costs and low work efficiency. Utility Model Content

Detailed Implementation

[0013] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Reference Figures 1 to 5 As shown, this utility model provides an automatic feeding device for a positioning feeder. In one embodiment, it includes a feeding hopper 1 and a feeding conveying device 2 arranged on one side of the feeding hopper 1. The feeding hopper 1 includes a tray conveying mechanism 11. The tray conveying mechanism 11 includes a tray fixing platform 111, and the top of the tray fixing platform 111 is provided with three tray through holes spaced apart. A tray conveying line 12 is arranged below each tray through hole, and a tray lifting mechanism 13 is arranged at one end of each tray conveying line 12. A tray picking mechanism 14 is installed at both ends of the tray through holes on the tray fixing platform 111, and a tray straightening mechanism 15 is also installed on both sides of the two tray through holes at both ends of the tray fixing platform 111. A tray translation mechanism 16 is also installed on the top of the tray fixing platform 111 along the length direction of the tray fixing platform 111, and the tray translation mechanism 16 is also driven and connected to a tray sliding plate 17.

[0015] In this embodiment, the unloading and conveying device 2 is provided in two sets. One unloading and conveying device 2 is arranged at each end of one side of the unloading hopper 1. Two tray conveying lines 12 located below both ends of the tray fixing platform 111 are used to transport empty trays. The middle tray conveying line 12 is used to unload trays filled with locators. During operation, empty trays are first manually stacked on the loading conveying lines at both ends. The loading conveying lines then transport the trays to the tray lifting mechanism 13 located at one end. The lifting mechanism 13 lifts the material tray upwards, causing the topmost material tray to rise to the tray-separating and picking mechanism 14. The unloading and conveying device 2 transfers the tested locator to the corresponding cavity of the material tray. After it is full, the tray-separating and picking mechanism 14 clamps the topmost material tray and lifts it. Then, the tray-separating translation mechanism 16 (which uses a motor lead screw drive) drives the tray-separating slide plate 17 to move below the material tray. The tray-separating and picking mechanism 14 places the material tray on the tray-separating slide plate 17.

[0016] Subsequently, the tray straightening mechanism 15 corrects the position of the tray on the tray slide plate 17. Then, the tray translation mechanism 16 drives the tray slide plate 17 to move to the middle position of the tray fixing table 111. The tray picking mechanism 14 at the middle position clamps the tray, the tray slide plate 17 moves away, and the tray picking mechanism 14 at the middle position places the tray on the tray lifting mechanism 13 at the middle position. The tray lifting mechanism 13 then places it on the tray conveyor line 12 at the middle position, and the tray conveyor line 12 transmits it to the next process.

[0017] In one embodiment, the tray picking mechanism 14 includes a tray lifting cylinder 141 installed on the top of the tray fixing platform 111, a tray translation cylinder 142 connected to the tray lifting cylinder 141, and a tray connecting horizontal plate 143 connected to the tray translation cylinder 142; a tray connecting vertical plate 144 is connected to each of the bottom ends of the tray connecting horizontal plate 143, and a tray picking block 145 is installed on each side of the tray connecting vertical plate 144; a first V-shaped groove is opened on the lower part of the tray picking block 145 near the tray through hole, and an extension support block 146 extends from the bottom of the tray picking block 145 toward the tray through hole.

[0018] With the cooperation of the splitting lifting cylinder 141 and the splitting translation cylinder 142, the splitting material picking block 145 can be driven to perform translation and lifting movements so that the splitting material picking block 145 can clamp the two ends of the material tray, thereby realizing the splitting. In this embodiment, a first V-shaped groove is provided on one side of the splitting material picking block 145 to achieve stable clamping of the material tray. At the same time, an extension support block 146 extends from the bottom of the splitting material picking block 145 towards the splitting through hole, which can support the material tray during the clamping process and further improve the clamping stability.

[0019] In addition, a disc guide sleeve is installed on the disc connecting vertical plate 144, and a disc pin is horizontally connected to the other side of the disc picking block 145; the disc pin moves through the disc guide sleeve; a first buffer spring 147 is also installed on the disc pin, and the first buffer spring 147 is located between the disc picking block 145 and the disc connecting vertical plate 144. When the disc picking block 145 clamps the disc, the first buffer spring 147 can play a buffering role, which can buffer the impact force between it and the disc, thereby avoiding damage to the disc due to mechanical collision.

[0020] In one embodiment, the tray straightening mechanism 15 includes a straightening translation cylinder 151 mounted on the top of the tray fixing platform 111, and a straightening push plate 152 connected to the straightening translation cylinder 151. After the tray picking mechanism 14 places the tray on the tray sliding plate 17, the position may shift. At this time, the straightening translation cylinder 151 can drive the straightening push plate 152 to move, thereby centering and straightening the tray. At the same time, a tray pressing mechanism 18 is also installed on each side of the two tray through holes at both ends of the tray fixing platform 111. The tray pressing mechanism 18 includes a pressing translation cylinder 181 and a tray pressing plate 182 connected to the pressing translation cylinder 181. The top of the tray pressing plate 182 extends a pressing extension 183 towards the tray through hole. When the tray-separating and picking mechanism 14 clamps the top tray, the pressing and translating cylinder 181 drives the tray-separating pressure plate 182 to move, causing the pressing extension 183 to insert between the top tray and the second tray, thereby pressing down the second and lower trays and facilitating smooth tray separation by the tray-separating and picking mechanism 14. Furthermore, a tray-separating limiting block is installed on each of the top two sides and both ends of the tray-separating slide plate 17. After the tray-separating and picking mechanism 14 places the tray on the tray-separating slide plate 17, the tray-separating straightening mechanism 15 straightens it, and the limiting blocks limit its four sides, ensuring the stability of the tray-separating slide plate 17 during movement.

[0021] In one embodiment, the material tray lifting mechanism 13 includes a lifting fixing frame, a lifting mechanism installed on one side of the lifting fixing frame, and a lifting frame connected to the lifting mechanism; a lifting support plate is also connected to the top of the lifting frame. The lifting mechanism uses a motor screw drive to drive the lifting frame to rise and fall, thereby lifting the material tray via the lifting support plate. Simultaneously, lifting guide bars are connected vertically to both sides and both ends of the tray through-hole. When the material tray lifting mechanism 13 lifts the material tray, the lifting guide bars guide and limit its movement on all four sides, ensuring the material tray remains stable during lifting.

[0022] In one embodiment, the unloading and conveying device 2 includes an unloading robotic arm 21, an unloading mounting plate 22 connected to the unloading robotic arm 21, an unloading lifting cylinder 23 mounted on the upper part of one side of the unloading mounting plate 22, and an unloading lifting plate 24 slidably arranged on one side of the unloading mounting plate 22 and connected to the unloading lifting cylinder 23; a first slide rail assembly is arranged along the length direction of the unloading mounting plate 22 on the lower part of one side of the unloading mounting plate 22, and a plurality of variable pitch guide plates 25 are slidably connected on the first slide rail assembly; an unloading transfer suction nozzle 26 is also installed on the lower part of one side of each variable pitch guide plate 25, and an unloading transfer suction nozzle 26 is also installed on one side of each variable pitch guide plate 25. The part is also equipped with a bearing follower 27; one end of the feeding lifting plate 24 is provided with a plurality of first pitch holes 241, and the other end of the feeding lifting plate 24 is provided with a plurality of second pitch holes 242; the first pitch holes 241 are opened at an angle downward toward the second pitch holes 242, and the second pitch holes 242 are opened at an angle downward toward the first pitch holes 241; the bearing follower 27 on the pitch guide plate 25 located at one end of the feeding lifting plate 24 is arranged in the first pitch hole 241, and the bearing follower 27 on the pitch guide plate 25 located at the other end of the feeding lifting plate 24 is arranged in the second pitch hole 242.

[0023] In this embodiment, four variable pitch guide plates 25 are provided, with two variable pitch guide plates 25 arranged at each end of the unloading lifting plate 24. The unloading lifting plate 24 has two first variable pitch holes 241 and two second variable pitch holes 242, which are symmetrically arranged. The unloading lifting cylinder 23 can drive the unloading lifting plate 24 to rise and fall, so that the bearing follower 27 moves along the variable pitch holes, thereby driving the variable pitch guide plates 25 to slide along the first slide rail assembly to realize the variable pitch function.

[0024] Preferably, in this embodiment, a suction nozzle mounting base 28 is further installed on the lower part of one side of the variable pitch guide plate 25, and a feeding suction nozzle head 29 is further installed at the bottom of the suction nozzle mounting base 28; the feeding transfer suction nozzle 26 is installed at the bottom of the feeding suction nozzle head 29; the suction nozzle mounting base 28 has an L-shaped structure, and the L-shaped vertical end of the suction nozzle mounting base 28 is slidably connected to the lower part of one side of the variable pitch guide plate 25, and the feeding suction nozzle head 29 is installed at the bottom of the L-shaped horizontal end of the suction nozzle mounting base 28; the lower part of one side of the variable pitch guide plate 25 is located above the suction nozzle mounting base 28.
