Description

Technical Field

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

[0018] 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 mechanism. 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.

[0019] 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.

Simultaneously, a laser sensor is also installed on one side of the L-shaped horizontal end of the nozzle mounting base 28 to measure the height of the feeding and transferring nozzle 26.

[0020] In one embodiment, the material unloading 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 each end of the tray through hole 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.

[0021] In this embodiment, two tray conveyor lines 12 located below both ends of the tray fixing platform 111 are used to transport empty trays, and the middle tray conveyor line 12 is used to transport trays full of locators for unloading. During operation, empty trays are first stacked on the loading conveyor lines at both ends. The loading conveyor lines transport the trays to the tray lifting mechanism 13 located at one end. The tray lifting mechanism 13 lifts the trays up, so that the tray at the top layer rises to the tray picking mechanism 14. The unloading and transfer device 2 transfers the tested locators to the corresponding cavity of the tray. After it is full, the tray picking mechanism 14 clamps the top tray and lifts it up. Then, the tray translation mechanism 16 (the tray translation mechanism 16 adopts the transmission method of motor screw) drives the tray slide plate 17 to move below the tray. The tray picking mechanism 14 places the tray on the tray slide plate 17.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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 third buffer spring is also installed on the disc pin, and the third buffer spring 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 third buffer spring 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.

[0026] 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, the tray-separating straightening mechanism 15 corrects it, and the limiting blocks limit its four sides, ensuring the stability of the tray-separating slide plate 17 during movement.

[0027] 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.

[0028] In one embodiment, a carrier spreading device 5 is also arranged below the unloading conveyor line 3; the carrier spreading device 5 includes a spreading horizontal plate 51, a spreading lifting cylinder 52 installed on one side of the spreading horizontal plate 51, and a spreading lifting plate 53 connected to the spreading lifting cylinder 52; a plurality of spreading clamping cylinders 54 are spaced apart along the length of the top of the spreading lifting plate 53; the spreading clamping cylinders 54 also drive two spreading translation blocks 541 connected to each spreading translation block 541, and a spreading vertical rod 542 is connected to each spreading vertical rod 542; a spreading insert rod 543 extends upward from the middle of the top of the spreading vertical rod 542.

The top of each support frame 511 is connected to the bottom of one side of the unloading conveyor line 3. At the same time, a pressing connecting plate 557 is arranged on each side of the horizontal support plate 55, and a limiting pressure plate 558 is connected between the two pressing connecting plates 557. The limiting pressure plate 558 is located above the horizontal support plate 55, and several contoured through holes are opened in the length direction of the top of the limiting pressure plate 558. Each pressing connecting plate 557 is installed on one side of the unloading conveyor line 3.

[0030] During operation, the unloading conveyor line 3 connects to the upstream conveyor line to connect to the carrier and transports the carrier to the top of the spreading plate 55. Then, the spreading lifting cylinder 52 drives the spreading lifting plate 53 to rise, allowing the spreading rods 543 to be inserted into the corresponding holes at both ends of the carrier (the carrier is made of flexible material and has a certain degree of elasticity). Next, the spreading clamping cylinder 54 drives the two spreading rods 543 to move apart, slightly opening the placement slot in the middle of the top of the carrier. Then, the unloading and transferring device 2 removes the locator from the placement slot for unloading. This is simple and efficient. In this embodiment, four spreading clamping cylinders 54 are provided, which can spread four carriers at once, improving work efficiency. Simultaneously, the spreading... Lifting guide sleeves 531 are installed at both ends of the lifting plate 53; an opening carrier plate 55 is arranged above the opening lifting plate 53, and a lifting guide column 551 is connected to each of the bottom ends of the opening carrier plate 55; the lower part of each lifting guide column 551 is arranged to move through a lifting guide sleeve 531; a clearance notch 552 is also provided on the top two sides of the opening carrier plate 55 corresponding to the opening insert rod 543; a fourth buffer spring 553 is also sleeved on the outer wall of each lifting guide column 551; the fourth buffer spring 553 is located between the top of the opening lifting plate 53 and the bottom of the opening carrier plate 55; the bottom of the limiting pressure plate 558 is connected to the two ends of the contour through hole with a first positioning pin.

[0031] After the carrier is transferred to the top of the spread plate 55, the spread lifting cylinder 52 drives the spread lifting plate 53 to raise the spread plate 55. At this time, the spread plate 55 will lift the carrier upward until the carrier reaches the bottom of the limit pressure plate 558. The carrier has a pin hole corresponding to the first positioning pin. The first positioning pin will be inserted into the pin hole to position the carrier. The spread insertion rod 543 will pass through the clearance notch 552 and be inserted into the corresponding insertion holes at both ends of the carrier. Under the drive of the spread clamping cylinder 54, the carrier placement slot is opened and the unloading and transfer device 2 removes the locator.

[0032] In one embodiment, a first guide block 554 is installed at both ends of the top of the spreading carrier plate 55, and one end of the first guide block 554 is provided with a downwardly inclined guide surface 555; a limiting blocking platform 556 is also provided at the bottom of the lifting guide column 551. The two first guide blocks 554 installed at each end of the top of the spreading carrier plate 555 can play a limiting role, ensuring the stability of the carrier when it is lifted by spreading the carrier plate 55.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
