Description

Technical Field

[0001] The invention relates to the technical field of terminal forming, and in particular to a terminal picking and placing positioning carrier. Background Art

[0002] In the non-standard automation industry, terminal positioning is frequently used in tools and equipment. Inaccurate positioning during operation can easily lead to poor product positioning, impacting subsequent operation and causing functional and dimensional anomalies. Traditional fixed positioning pins are particularly prone to deformation and improper handling of components with small, irregular, or fragile dimensions, particularly those with stringent requirements for size and appearance. The introduction of this floating, adsorption-based positioning technology allows for effective product positioning and release, preventing a range of defects caused by poor handling and placement, and creating a solution that utilizes positioning pins and adsorption in conjunction.

[0003] According to Chinese patent CN119328691A, a flexible secondary positioning vacuum adsorption device and a positioning method thereof are disclosed. The device adsorbs the product located in the positioning groove through a vacuum adsorption part, and then pushes the positioning slider through a push rod to apply flexible push in two different directions to the product located in the positioning groove, thereby achieving precise positioning of the product. However, in actual operation, the terminal is relatively light in weight and needs to be adsorbed by the vacuum adsorption part with a larger suction force. Since the space in the adsorption channel is relatively narrow, it takes a certain amount of time for the adsorption channel 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, resulting in the terminal still being adsorbed when taking the material or the terminal still not being adsorbed when releasing the material, affecting the efficiency and reliability of terminal transportation.

[0004] Therefore, it is necessary to develop a terminal pick-and-place positioning vehicle to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a terminal picking and placing positioning carrier with high efficiency and high stability.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a terminal pick-up and placement positioning carrier, comprising: substrate; The moving assembly includes a positioning pin and upper and lower sliders that move synchronously, wherein the upper and lower sliders have sliding holes, and the sliding holes are in an oblique state; A transmission assembly includes a transmission rod and a follower shaft fixedly connected to the transmission rod, wherein the follower shaft extends into the sliding hole; A reset member, which abuts against the transmission rod; The adsorption part includes a connecting air hole for gas transmission, an air chamber connected to the connecting air hole and an air vent. The air chamber is formed by a depression from the lower surface of the substrate and / or the upper surface of the moving component. The air vent passes through the substrate from the air chamber.

[0007] Furthermore, the air chamber is located between the substrate and the moving component, and adjacent air chambers are communicated with each other.

[0008] Furthermore, the number and positions of the vent holes correspond to those of the positioning pin and are located on the side of the positioning pin.

[0009] Furthermore, the reset member includes a fixed block and a spring, and two ends of the spring respectively abut against the fixed block and the transmission rod.

[0010] Furthermore, the transmission rod has a limit groove formed by being recessed inward from the upper surface, and a cover plate is provided above the limit groove. The cover plate is fixedly connected to the base plate, the cover plate is located in the limit groove and the length of the limit groove is greater than the length of the cover plate. When the transmission rod moves, it interferes with the cover plate.

[0011] Furthermore, the upper and lower sliders have an air avoidance groove and the sliding hole. The air avoidance groove is formed by being recessed inward from the upper end surfaces of the upper and lower sliders. The two ends of the air avoidance groove pass through the side surfaces of the upper and lower sliders. The sliding hole passes through the other opposite side surface of the upper and lower sliders and is connected to the air avoidance groove.

[0012] Furthermore, the end of the transmission rod extends into the air-avoiding groove, and both ends of the follower shaft expose the outer surface of the end of the transmission rod and extend into the sliding hole respectively.

[0013] Furthermore, a sliding sleeve is sleeved on the exposed position of the follower shaft, and the sliding sleeve extends into the sliding hole.

[0014] Furthermore, a plurality of protrusions are formed on the surface of the substrate, and the shapes of the plurality of protrusions are changed according to the shapes of the terminals, so as to support the terminals and keep the terminals in a horizontal state.

[0015] Furthermore, a magnetic component is embedded in the protrusion, and the magnetic component magnetically adsorbs the terminal.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the present invention is a terminal picking and placing positioning carrier with the characteristics of high efficiency and high stability. While the transmission component drives the positioning for the terminal, the air chamber airtightness is directly controlled by the bonding or separation of the substrate and the transmission component, ensuring that the adsorption force is quickly released, avoiding terminal adhesion during picking and placing, and overcoming technical difficulties such as inaccurate positioning and adsorption delay in the picking and placing of 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.

[0019] To further illustrate the technical means and effectiveness of the present invention in achieving its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, describes in detail the specific implementation, structure, features, and effectiveness of the terminal pick-and-place positioning carrier proposed in accordance with the present invention. In the following description, references to different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0020] Unless defined otherwise, 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 belongs.

[0021] The specific solution of the terminal picking and placing positioning carrier provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Please see Figures 1 to 4 The present invention is a terminal picking and placing positioning carrier, which includes a substrate 1, a moving component 2 corresponding to the substrate 1, a transmission component 3 that pushes the moving component 2 toward or away from the substrate 1, and a reset component 4 that helps the transmission component 3 to reset.

[0023] Please see Figures 1 to 2The shape of the base plate 1 can be changed according to needs to support the aforementioned components. The base plate 1 has a through slot 11 and a plurality of guide holes 12. The through slot 11 is formed by a recessed groove from the upper surface of the base plate 1. The two ends of the through slot 11 extend through the side surface of the base plate 1 to accommodate the transmission assembly 3. The guide holes 12 extend through the upper and lower surfaces of the base plate 1 and are internally mounted with linear bearings 13.

[0024] Please see Figures 2 to 3 The moving assembly 2 includes a mounting plate 21, a pressure plate 22 fixedly connected to the mounting plate 21, and positioning pins 23 provided 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 vertically penetrates the pressure plate 22 and the base plate 1, and the 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. Secondly, 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.

[0025] The movable assembly 2 is fixedly mounted with upper and lower sliders 25. The bottoms of the upper and lower sliders 25 are fixedly connected to the mounting plate 21 or the pressure plate 22, and the tops thereof extend through the base plate 1 and into the through-slot 11. Specifically, the upper and lower sliders 25 have a clearance groove 251 and a slide hole 252. The clearance groove 251 is formed inwardly from the upper end surfaces of the upper and lower sliders 25. The two ends of the clearance groove 251 extend through the side surfaces of the upper and lower sliders 25. The slide hole 252 extends through the other opposing side surfaces of the upper and lower sliders 25 and communicates with the clearance groove 251. Specifically, the slide hole 252 is arranged obliquely, that is, the slide hole 252 is an elongated hole with one end being taller than the other.

[0026] Please see 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 that is sleeved on the follower shaft 32. The transmission rod 31 is disposed within the through slot 11 and is driven by an external force (such as a motor, cylinder, or other power source) to move along the through slot 11. The follower shaft 32 extends through both sides of the transmission rod 31. Both ends of the follower shaft 32 are exposed at the outer surface of the end of the transmission rod 31. The exposed portions are sleeved on the sliding sleeves 33 and extend into the sliding holes 252, allowing the sliding sleeves 33 to move along the sliding holes 252.

[0027] Preferably, the transmission rod 31 has a limit groove 34 formed by being recessed inward from the upper surface, and a cover plate 35 is provided above the limit 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 limit groove 34 and the length of the limit 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, thereby limiting the forward distance and reset distance of the transmission rod 31.

[0028] Please see Figure 3The reset member 4 includes a fixed block 41 and a spring 42. The fixed block 41 is installed in the through slot 11, opposite to the end of the transmission rod 31, and the two ends of the spring 42 respectively abut the fixed block 41 and the transmission rod 31.

[0029] Please see Figure 2 and Figure 4 The terminal pick-and-place positioning device of the present invention further includes a suction portion 5, which includes a connecting air hole 51, an air chamber 52 connected to the connecting air hole 51, and a plurality of vent holes 53 connected to 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 sucks or blows air into the air chamber 52 and the vent holes 53 through the connecting air hole 51.

[0030] The air chamber 52 is located between the substrate 1 and the pressure plate 22, and is formed by a recess in the lower surface of the substrate 1 and / or the upper surface of the pressure plate 22. It is connected to 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 needs. In this embodiment, the air chamber 52 is a rectangular body with four regions distributed, and adjacent air chambers 52 are connected to each other.

[0031] A plurality of vent holes 53 pass through 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 according to the number and position of the positioning pins 23 . The vent holes 53 are usually located on one side of the positioning pins 23 .

[0032] Please see Figure 1 In another embodiment, a plurality of protrusions 14 are formed on the surface of the substrate 1. The shapes of the plurality of protrusions 14 are changed according to the shapes of the terminals and are used to support the terminals so that the terminals are generally in a horizontal state.

[0033] In another embodiment, a plurality of protrusions 14 are embedded with magnetic components 15 , and the magnetic components 15 magnetically attract the terminals.

[0034] When a terminal picking and placing positioning carrier of the present invention is used, the substrate 1 is in a fixed state, and the transmission rod 31 is pushed by external force to move along the groove 11 toward the outside of the substrate 1, and the follower shaft 32 and the sliding sleeve 33 move along the sliding hole 252 accordingly. The sliding sleeve 33 rotates, and the follower shaft 32 moves from the high position of the sliding hole 252 to the low position. The upper and lower sliders 25 are forced to move toward the upper surface of the substrate 1, driving 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 substrate 1, and the robot (not shown) places the terminal on the substrate 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 substrate 1 are fitted together, and the adsorption part 5 forms a relatively closed state. The external air source draws air into the air chamber 52 and the vent hole 53 through the connecting air hole 51, fixes the position of the terminal, and completes the terminal loading process.

[0035] When the terminal needs to be cut, the transmission rod 31 is pushed by external force to move along the groove 11 into the substrate 1, and 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 upper part. The upper and lower sliders 25 are forced away from the substrate 1, driving the mounting plate 21, the pressure plate 22 and the positioning pin 23 to move accordingly. The end of the positioning pin 23 exits the upper surface of the substrate 1, the pressure plate 22 and the substrate 1 are separated, and the adsorption part 5 forms an open state, stops adsorbing the terminal, and removes the terminal.

[0036] The present invention is a terminal picking and placing positioning carrier with the characteristics of high efficiency and high stability. While the transmission component drives the positioning for the terminal, the air chamber airtightness is directly controlled by the bonding or separation of the substrate and the transmission component, ensuring that the adsorption force is quickly released and avoiding terminal adhesion during picking and placing. It overcomes the technical difficulties such as inaccurate positioning and adsorption delay in the picking and placing of small irregular terminals, and has high precision, high stability and high efficiency, and is suitable for precision terminal production scenarios with strict requirements on size and appearance.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the scope of protection of the present invention.
