Description

Technical Field

[0001] This invention relates to the field of terminal forming technology, and more particularly to a terminal picking and positioning carrier. Background Technology

[0002] In the non-standard automation industry, terminal product positioning is frequently used in jigs and equipment. Inaccurate positioning during operation can easily lead to poor product position, affecting subsequent actions and causing functional and dimensional abnormalities. This is especially true for small, irregular, and thin components with high dimensional and aesthetic requirements; traditional fixed positioning pins are prone to deformation and abnormal placement / removal. Introducing this floating, adsorption-based positioning technology can effectively position and release products, avoiding a series of product defects caused by improper placement / removal, creating a solution where positioning pins and adsorption work together.

[0003] According to Chinese patent CN119328691A, a flexible secondary positioning vacuum adsorption device and its positioning method are disclosed. This device adsorbs products located in the positioning groove through a vacuum adsorption unit, and then pushes the positioning slider with a push rod to apply flexible push in two different directions to the products located in the positioning groove, so as to achieve precise positioning of the products. However, in actual operation, the terminals are relatively light and need to be adsorbed by the vacuum adsorption unit with a large suction force. In addition, due to the relatively narrow space in the adsorption channel, the adsorption channel needs a certain amount of time to switch from the adsorption state to the non-adsorption state or from the non-adsorption state to the adsorption state. Moreover, the length of the adsorption channel is different, and this time is difficult to control. As a result, the terminals are still adsorbed when picking up the material or not adsorbed when discharging the material, which affects the efficiency and reliability of terminal transfer.

[0004] Therefore, it is necessary to develop a terminal picking and positioning carrier to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency and high-stability terminal picking and positioning carrier.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a terminal picking and placing positioning carrier, comprising:

[0007] substrate;

[0008] The moving component includes a positioning pin and a sliding block that move synchronously, the sliding block having a sliding hole that is angled.

[0009] The transmission assembly includes a transmission rod and a follower shaft fixedly connected to the transmission rod, the follower shaft extending into the sliding hole;

[0010] The reset element abuts against the transmission rod;

[0011] The adsorption section includes a connecting air hole for gas delivery, an air chamber communicating with the connecting air hole, and a vent hole. The air chamber is recessed from the lower surface of the substrate and / or the upper surface of the moving component, and the vent hole extends through the substrate from the air chamber.

[0012] Furthermore, the air chamber is located between the substrate and the moving component, and adjacent air chambers are interconnected.

[0013] Furthermore, the number and position of the vent holes correspond to the positioning pin, and are located to the side of the positioning pin.

[0014] Furthermore, the reset component includes a fixing block and a spring, with the two ends of the spring abutting against the fixing block and the transmission rod, respectively.

[0015] Furthermore, the transmission rod has a limiting groove formed by a recess inward from the upper surface, and a cover plate is provided above the limiting groove. The cover plate is fixedly connected to the base plate. The cover plate is located in the limiting groove and the length of the limiting groove is greater than the length of the cover plate. When the transmission rod moves, it interferes with the cover plate.

[0016] Furthermore, the upper and lower sliders have a clearance groove and a sliding hole. The clearance groove is formed by an inward recess from the upper end face of the upper and lower sliders. Both ends of the clearance groove penetrate the side surface of the upper and lower sliders. The sliding hole penetrates the other opposite side surface of the upper and lower sliders and communicates with the clearance groove.

[0017] Furthermore, the end of the transmission rod extends into the clearance groove, and both ends of the follower shaft are exposed on the outer surface of the end of the transmission rod, respectively extending into the sliding hole.

[0018] Furthermore, a sliding sleeve is fitted onto the exposed position of the follower shaft, and the sliding sleeve extends into the sliding hole.

[0019] Furthermore, a plurality of protrusions are formed on the surface of the substrate, and the shape of the protrusions changes according to the shape of the terminal to support the terminal and keep the terminal in a horizontal state.

[0020] Furthermore, a magnetic component is embedded in the protrusion, which magnetically attracts the terminal.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention is a terminal picking and placing positioning carrier with high efficiency and high stability. While the transmission component drives the positioning of the terminal, the air chamber is directly controlled by the bonding or separation of the substrate and the transmission component to ensure that the adsorption force is quickly released and the terminals are avoided from sticking together during picking and placing. It overcomes the technical problems of inaccurate positioning and adsorption delay in picking and placing small irregular terminals. It has high precision, high stability and high efficiency, and is suitable for precision terminal production scenarios with strict requirements for size and appearance. Attached Figure Description

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0029] The specific solution of the terminal picking and positioning carrier provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Please refer to Figures 1 to 4 The present invention is a terminal picking and placing positioning carrier, which includes a base plate 1, a moving component 2 corresponding to the base plate 1, a transmission component 3 for pushing the moving component 2 closer to or away from the base plate 1, and a reset component 4 for helping the transmission component 3 to reset.

[0031] Please refer to Figures 1 to 2The shape of the substrate 1 can be changed according to the requirements to support the aforementioned components. The substrate 1 has a through groove 11 and several guide holes 12. The through groove 11 is formed by recessing from the upper surface of the substrate 1. Both ends of the through groove 11 penetrate the side surface of the substrate 1 to accommodate the transmission assembly 3. The guide holes 12 penetrate the upper and lower surfaces of the substrate 1 and a linear bearing 13 is installed inside them.

[0032] Please refer to Figures 2 to 3 The movable component 2 includes a mounting plate 21, a pressure plate 22 fixedly connected to the mounting plate 21, and positioning pins 23 disposed on the mounting plate 21 and the pressure plate 22. The mounting plate 21 and the pressure plate 22 are located below the base plate 1. The bottom of the positioning pin 23 is fixedly connected to the mounting plate 21, and its top extends vertically upward through the pressure plate 22 and the base plate 1. Its end can extend out of the upper surface of the base plate 1. The pressure plate 22 ensures that the positioning pin 23 is arranged vertically. Furthermore, the mounting plate 21 is provided with a plurality of sliding guide posts 24. The bottom of the plurality of sliding guide posts 24 is fixedly connected to the mounting plate 21, and the top extends vertically upward into the guide hole 12, cooperating with the linear bearing 13.

[0033] The movable component 2 is fixedly mounted with upper and lower sliders 25. The bottom of the upper and lower sliders 25 is fixedly connected to the mounting plate 21 or the pressure plate 22, and its top passes through the base plate 1 and extends into the through groove 11. Specifically, the upper and lower sliders 25 have a clearance groove 251 and a sliding hole 252. The clearance groove 251 is formed by a recess inward from the upper end face of the upper and lower sliders 25, and both ends of the clearance groove 251 penetrate the side surface of the upper and lower sliders 25. The sliding hole 252 penetrates the other opposite side surface of the upper and lower sliders 25 and communicates with the clearance groove 251. Specifically, the sliding hole 252 is arranged obliquely, that is, the sliding hole 252 is an elongated hole, and the height of one end is greater than the height of the other end.

[0034] Please refer to Figure 3 The transmission assembly 3 includes a transmission rod 31, a follower shaft 32 mounted at the end of the transmission rod 31, and a sliding sleeve 33 sleeved on the follower shaft 32. The transmission rod 31 is located in the through groove 11 and is driven by an external force (such as a power source like a motor or cylinder) to move along the through groove 11. The follower shaft 32 passes through both sides of the transmission rod 31, and both ends of the follower shaft 32 are exposed on the outer surface of the end of the transmission rod 31. After the exposed positions are sleeved on the sliding sleeve 33, they extend into the sliding hole 252 respectively, and the sliding sleeve 33 can move along the sliding hole 252.

[0035] Preferably, the transmission rod 31 has a limiting groove 34 formed by recessing from the upper surface. A cover plate 35 is provided above the limiting groove 34. The cover plate 35 is fixedly connected to the base plate 1 by bolts or screws. The cover plate 35 is located in the limiting groove 34 and the length of the limiting groove 34 is greater than the length of the cover plate 35. When the transmission rod 31 moves, it interferes with the cover plate 35, limiting the forward distance and reset distance of the transmission rod 31.

[0036] Please refer to Figure 3The reset component 4 includes a fixing block 41 and a spring 42. The fixing block 41 is installed in the through groove 11 and is opposite to the end of the transmission rod 31. The two ends of the spring 42 abut against the fixing block 41 and the transmission rod 31 respectively.

[0037] Please refer to Figure 2 and Figure 4 The terminal picking and positioning carrier of the present invention further includes an adsorption part 5, which includes a connecting air hole 51, an air chamber 52 communicating with the connecting air hole 51, and a plurality of vent holes 53 communicating with the air chamber 52. The connecting air hole 51 passes through the mounting plate 21 and the pressure plate 22 and is connected to an external air source (not shown). The external air source draws in or blows air into the air chamber 52 and the vent holes 53 through the connecting air hole 51.

[0038] The air chamber 52 is located between the substrate 1 and the pressure plate 22, and is formed by a recess from the lower surface of the substrate 1 and / or the upper surface of the pressure plate 22, and communicates with the connecting air hole 51 and the vent hole 53. Specifically, the shape and position of the air chamber 52 can be changed according to the requirements. In this embodiment, the air chamber 52 is a rectangular body, distributed in four regions, and adjacent air chambers 52 are interconnected.

[0039] A number of vent holes 53 penetrate the upper and lower surfaces of the substrate 1 and communicate with the air chamber 52. The number and position of the vent holes 53 vary depending on the number and position of the positioning pins 23. The vent holes 53 are usually located on one side of the positioning pins 23.

[0040] Please refer to Figure 1 In another embodiment, a plurality of protrusions 14 are formed on the surface of the substrate 1. The shape of the plurality of protrusions 14 changes according to the shape of the terminal and is used to support the terminal so that the terminal is generally in a horizontal state.

[0041] In another embodiment, a plurality of protrusions 14 are embedded with magnetic components 15, which magnetically attract the terminals.

[0042] When the terminal picking and positioning carrier of the present invention is used, the base plate 1 is in a fixed state. The transmission rod 31 is pushed by external force to move outward along the through groove 11. The follower shaft 32 and the sliding sleeve 33 move along the sliding hole 252. The sliding sleeve 33 rotates, and the follower shaft 32 moves from the high point to the low point of the sliding hole 252. The upper and lower sliders 25 are moved towards the upper surface of the base plate 1 by force, which drives the mounting plate 21, the pressure plate 22 and the positioning pin 23 to move accordingly. The end of the positioning pin 23 extends out of the upper surface of the base plate 1. The robot (not shown) puts the terminal on the base plate 1, so that the positioning pin 23 extends into the positioning hole of the terminal. At the same time, the terminal covers the vent hole 53. The pressure plate 22 and the base plate 1 are attached to each other, and the adsorption part 5 forms a relatively sealed state. The external air source draws air into the air chamber 52 and the vent hole 53 through the connecting air hole 51 to fix the position of the terminal and complete the terminal loading process.

[0043] When the terminal needs to be unloaded, the transmission rod 31 is pushed by external force to move along the through groove 11 into the substrate 1. The follower shaft 32 and the sliding sleeve 33 move along the sliding hole 252. The sliding sleeve 33 rotates, and the follower shaft 32 moves from the lower part of the sliding hole 252 to the higher part. The upper and lower sliders 25 are forced away from the substrate 1, which drives the mounting plate 21, the pressure plate 22 and the positioning pin 23 to move. The end of the positioning pin 23 exits the upper surface of the substrate 1, the pressure plate 22 and the substrate 1 separate, the adsorption part 5 is in an open state, the adsorption of the terminal stops, and the terminal is removed.

[0044] This invention is a terminal picking and placing positioning carrier with high efficiency and high stability. The transmission component drives the positioning of the terminal, and the air chamber is directly controlled by the bonding or separation of the substrate and the transmission component to ensure that the adsorption force is quickly released and the terminals are avoided from sticking together during picking and placing. It overcomes the technical problems of inaccurate positioning and adsorption delay in picking and placing small irregular terminals. It has high precision, high stability and high efficiency, and is suitable for precision terminal production scenarios with strict requirements on size and appearance.
