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. Background Technology

[0002] In the production process of locators (such as GPS positioning modules), it is necessary to perform tests on current, resistance, and other related parameters. This requires separating the product from the hopper onto a tray, picking the product from the tray, and transferring it to the corresponding carrier. Finally, the carrier is moved to the appropriate testing equipment for testing. Currently, most small and medium-sized enterprises use manual transfer and loading, which is inefficient and costly. Some enterprises use robotic arms for automated transfer and loading, but robotic arms have a simple structure, and the positions of the multiple transfer suction cups on the robotic arm are fixed. The spacing between the acupoints on the tray that hold the product is different from the spacing between the acupoints on the carrier. This requires a variable-pitch platform and two sets of robotic arms (with different spacing between the transfer suction cups on the two sets of robotic arms). One robotic arm is used to transfer the product from the tray to the variable-pitch platform, which adjusts the pitch. Then, the other set of robotic arms transfers the adjusted product to the carrier. This operation is complex and costly. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic feeding device for a positioner. This device integrates the pitch-changing function of the pitch-changing platform into a transfer and loading device. Through the pitch-changing translation mechanism of the transfer and loading device, the pitch of the pitch-changing feeding suction cup is directly changed. Then, driven by the transfer and flipping mechanism, the positioner picked up by the pitch-changing feeding suction cup is flipped 180° so that the positioner faces upward. Finally, the feeding and transfer device picks up the positioner and transfers it into the carrier. There is no need to add an additional pitch-changing platform, which reduces costs and is highly practical.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 4 As shown, this utility model provides an automatic feeding device for a locator. In one embodiment, it includes a transfer device 1 and a feeding and transfer device 2. The feeding and transfer device 2 includes a feeding robotic arm 21, a first feeding seat 22 connected to the feeding robotic arm 21, and a plurality of feeding and transfer modules installed on one side of the first feeding seat 22. The feeding and transfer module includes a transfer Z-axis cylinder 23 installed on one side of the first feeding seat 22, a transfer lifting plate 24 connected to the transfer Z-axis cylinder 23, a transfer lifting seat 25 connected to one side of the transfer lifting plate 24, and a transfer lifting seat 25 connected to the transfer lifting plate 24. The base 25 has a transfer connecting horizontal plate 26 at its bottom; a transfer rotary motor 27 is also installed on the transfer connecting horizontal plate 26, and the transfer rotary motor 27 also drives a transfer suction head 28; a first transfer suction head 281 is also installed at the bottom of the transfer suction head 28; a first air blowing block 261 is connected to each end of the bottom of the transfer connecting horizontal plate 26, and the transfer suction head 28 is located between the two first air blowing blocks 261; a first air blowing port is opened at the bottom of the first air blowing block 261, and a first air source connector communicating with the first air blowing port is also installed on one side of the first air blowing block 261.

[0021] In this embodiment, the transfer device 1 includes a transfer robotic arm 11, a transfer connecting seat 12 connected to the transfer robotic arm 11, a transfer flipping mechanism 13 mounted on the transfer connecting seat 12, and a transfer flipping plate 14 connected to the transfer flipping mechanism 13; a variable pitch translation mechanism 15 is installed on one side of the transfer flipping plate 14 along its length, and the variable pitch translation mechanism 15 is also driven to connect a variable pitch connecting plate 16; a plurality of variable pitch sliding plates 17 are also slidably connected to one side of the transfer flipping plate 14 along its length, and each variable pitch sliding plate 17... A variable pitch guide groove 171 is opened on one side along the length of the transfer and flipping plate 14; a variable pitch sliding plate 17 arranged near the variable pitch connecting plate 16 is connected to the variable pitch connecting plate 16, and a variable pitch connecting rod 172 is connected to one side of each of the other variable pitch sliding plates 17, and one end of the variable pitch connecting rod on each variable pitch sliding plate 17 is inserted into the variable pitch guide groove 171 on the adjacent variable pitch sliding plate 17 to its right; a variable pitch suction cup seat 173 is also connected to the variable pitch sliding plate 17, and a variable pitch feeding suction cup 174 is installed at the bottom of the variable pitch suction cup seat 173.

[0022] The transfer robotic arm 11 and the loading robotic arm 21 can be existing robots that can move and rotate freely in space. Four sets of variable-pitch sliding plates 17 are provided (the number of variable-pitch sliding plates 17 can be adaptively adjusted according to actual usage requirements). One variable-pitch sliding plate 17 is connected to the variable-pitch connecting plate 16, and the other three variable-pitch sliding plates 17 are linked by the variable-pitch connecting rod 172 and the variable-pitch guide groove 171. During operation, the transfer robotic arm 11 first drives the transfer flipping plate 14 to move to the predetermined material picking position, then the variable-pitch loading suction cup 174 picks up the locator, and the transfer robotic arm 11 then drives the transfer flipping plate 14 to move to the material placement position, that is, below the loading and transfer device 2. Figure 3 As shown, the spacing between the variable pitch sliding plates 17 is relatively wide at this time, requiring pitch adjustment to reduce the distance between them to correspond with the spacing between the loading and transfer modules (there are four sets of loading and transfer modules) and the spacing between the cavities on the carrier. At this time, the variable pitch translation mechanism 15 can drive the variable pitch connecting plate 16 to move one of the variable pitch sliding plates 17 to the left, while the variable pitch connecting rod 172 on the adjacent variable pitch sliding plate 17 will move along the variable pitch guide groove 171 to its right end, thus adjusting the pitch. As the connecting plate 16 continues to move to the left, the inner wall of the right end of the variable pitch guide groove 171 will exert a leftward thrust on the variable pitch connecting rod 172, thereby driving the variable pitch sliding plate 17 connected to it to also move to the left, reducing the distance between it and other variable pitch sliding plates 17, until the distance adjustment of all variable pitch sliding plates 17 is completed. Then, the transfer and flipping mechanism 13 drives the transfer and flipping plate 14 to flip 180°, so that the locator faces upward, the loading and transfer module performs aerial material retrieval, and then transfers it into the carrier.

[0023] The loading and transfer module can pick up the transfer locator through the first transfer nozzle 281. At the same time, the transfer rotary motor 27 can drive the first transfer nozzle 281 to rotate the locator to adjust the angle and make it easier to place it in the corresponding position of the carrier. In addition, a first air blowing block 261 is connected to each end of the bottom of the transfer connecting plate 26. Air can be blown into the carrier through the first air blowing port to clean the dust and impurities on the carrier and ensure that the product is placed flat in the carrier.

[0024] Preferably, the motor shaft of the transfer rotary motor 27 has an axially hollow structure, and the two ends of the motor shaft are arranged to pass through the top and bottom of the transfer rotary motor 27, respectively; the transfer suction head 28 is installed at the bottom of the motor shaft of the transfer rotary motor 27, and a second air source connector is also installed at the top of the motor shaft of the transfer rotary motor 27. The transfer rotary motor 27 can be an existing dual-axis motor. Meanwhile, the transfer lifting seat 25 is slidably connected to the lower part of one side of the transfer lifting plate 24, and a transfer pad 251 is connected to the top of the transfer lifting seat 25. A transfer fixing block 252 is horizontally connected to the upper part of one side of the transfer lifting plate 24. The loading and transfer module also includes a first equalizing screw 253, with one end of the first equalizing screw 253 with a nut located above the transfer fixing block 252, and the other end of the first equalizing screw 253 movably passing through the transfer fixing block 252. A first pressure sensor 254 is also installed on the top of the transfer pad 251, and the other end of the first equalizing screw 253 is connected to the top of the first pressure sensor 254. A first buffer spring 255 is also sleeved on the portion of the first equalizing screw 253 located between the first pressure sensor 254 and the transfer fixing block 252. A first buffer spring 255 is provided. When the first transfer nozzle 281 picks up and transfers the positioner, it can buffer the downward pressure of the first transfer nozzle 281 on the positioner to avoid excessive pressure and damage to the product. In addition, a cable tray 256 is also connected to the transfer pad 251 to facilitate wiring.

[0025] Preferably, the pitch-changing link 172 has an L-shaped structure, with its horizontal L-shaped end connected to one side of the pitch-changing sliding plate 17, and its vertical L-shaped end movably inserted into the pitch-changing guide groove 171 on another pitch-changing sliding plate 17. A first pitch-changing slide rail assembly is arranged along the length of one lower side of the transfer and flipping plate 14, and the upper other side of the pitch-changing sliding plate 17 is slidably connected to the first pitch-changing slide rail assembly. The slidable connection between the pitch-changing sliding plate 17 and the first pitch-changing slide rail assembly guides the pitch-changing sliding plate 17 during translation, ensuring its translational stability.

[0026] In one embodiment, the variable pitch suction cup seat 173 is arranged below the variable pitch sliding plate 17, and a second variable pitch slide rail assembly is also arranged vertically on the lower part of the other side of the variable pitch sliding plate 17; an extension vertical plate 175 extends upward from one top end of the variable pitch suction cup seat 173, and the extension vertical plate 175 is slidably connected to the second variable pitch slide rail assembly (a stop block extends upward from the top of the extension vertical plate 175 towards the second variable pitch slide rail assembly); a second buffer spring 176 is also connected vertically to the other top end of the variable pitch suction cup seat 173, and a first insertion hole is opened at the bottom of the variable pitch sliding plate 17, and the upper part of the second buffer spring 176 is inserted into the first insertion hole; a first U-shaped groove is also opened at the bottom of the variable pitch suction cup seat 173, and the variable pitch feeding suction cup 174 is installed at the bottom of the first U-shaped groove.

[0027] The variable pitch feeding suction cup 174 is partially exposed outside the first U-shaped groove. When the suction cup is used to pick up the positioner, the second buffer spring 176 can buffer the downward pressure of the variable pitch feeding suction cup 174 on the product to avoid damaging the product. Preferably, a buffer pad 177 is also connected to each end of the bottom of the variable pitch suction cup seat 173, which can also play a role in buffering and protection.

[0028] In a preferred embodiment, the variable pitch translation mechanism 15 includes a variable pitch translation cylinder mounted on one side of the transfer tilting plate 14, and a first floating joint connected to the output shaft of the variable pitch translation cylinder; the upper part of the variable pitch connecting plate 16 is connected to the first floating joint. Driven by the variable pitch translation cylinder, the variable pitch connecting plate 16 can be moved, thereby driving the variable pitch sliding plate 17 to move, realizing a variable pitch action. Simultaneously, the transfer tilting mechanism 13 includes a tilting motor 131, a tilting reducer 132 connected to the tilting motor 131, and a tilting connecting block 133 connected to the tilting reducer 132; one end of the transfer tilting plate 14 is connected to the tilting connecting block 133. The use of a motor and reducer as the driving method ensures the stability of the rotation of the transfer tilting plate 14.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
