Description

Technical Field

[0001] This utility model belongs to the field of PCB manufacturing, and specifically relates to a feeding robot for a PCB testing machine. Background Technology

[0002] In various electronic products, PCB boards are often used as core electronic components. To ensure their reliability, various performance parameters need to be tested during the manufacturing process. Before testing, a robotic arm is usually used to feed the PCB board into the testing equipment. Before the board is picked up by the robotic arm, its position on the support plate needs to be positioned. Existing positioning mechanisms usually only push the board to a designated position on the support plate and make it abut against the limiting member to achieve the positioning effect. Existing methods cannot detect whether the board is tightly attached to the limiting member. If the board is not tightly attached to the limiting member, the positioning effect cannot be achieved.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figures 1-9 As shown, this utility model provides a PCB testing machine feeding robot, including a chassis 1. The chassis 1 has a feeding position 10 and a transport position 20. A support plate 11 is provided in the feeding position 10. An inlet 12 is provided on one side of the inner wall of the feeding position 10, located on the support plate 11. The support plate 11 has several openings 111, each containing a suction cup 112 for adsorbing PCB components. A positioning mechanism 3 for positioning PCB components is provided at the top of the support plate 11. A first driving member 13 is provided at the bottom of the feeding position 10 for driving the support plate 11 to move into the transport position 20. The top of the feeding position 10 is provided with a second driving component 14 and a mounting bracket 141. The second driving component 14 is used to drive the mounting bracket 141 to move horizontally above the material support plate 11. The mounting bracket 141 is equipped with a CCD camera 142 for identifying the plates on the material support plate 11. The transport position 20 is provided with a discharge port 2 on one side. The top of the transport position 20 is provided with a third driving component 21 and a vertical driving component 22. The third driving component 21 is used to drive the vertical driving component 22 to pass through the discharge port 2 and enter and exit the machine housing 1. The output end of the vertical driving component 22 is connected to a plate picker 221.

[0031] Furthermore, such as Figure 4As shown, the number of the second driving members 14 is at least two sets, and each second driving member 14 is arranged along the extension direction of the second positioning rod 118. The number of the mounting bracket 141 and the CCD camera 142 corresponds to the number of the second driving members 14. The mounting bracket 141 includes a slider 143 and an L-shaped base 144. The slider 143 is driven to cooperate with the second driving members 14. A fourth driving member 4 is provided at the bottom of the slider 143 for driving the base 144 to slide at the bottom of the slider 143. The horizontal part of the base 144 is slidably connected to the bottom of the slider 143. The CCD camera 142 is mounted on the top of the vertical part of the base 144. A fill light 145 and a laser pointer 146 are provided at the bottom of the vertical part of the base 144. The laser pointer 146 is used to emit a laser towards the shooting point of the CCD camera 142. Specifically, the sheet metal enters the housing 1 through the feed inlet 12 and is placed on the support plate 11. After being positioned by the positioning mechanism 3, the CCD camera 142 needs to detect the gap between the sheet metal and the second positioning rod 118. The second drive member 14 and the fourth drive member 4 are used to adjust the position of the CCD camera 142. When the CCD camera 142 moves, the second drive member 14 drives the CCD camera 142 to move along the long side of the support plate 11, and the fourth drive member 4 drives the CCD camera 142 to move along the wide side of the support plate 11. It is worth noting that the second drive member 14 and the fourth drive member 4 can be lead screw assemblies. The lead screw assembly can achieve the movement accuracy of the CCD camera 142, thereby... The CCD camera 142 can better identify the recognition area of ​​the board. At least two sets of CCD cameras 142 can be set, and each set is equipped with the same number of second drive units 14 and fourth drive units 4 to control the position of each CCD camera 142. Furthermore, the second drive units 14 with the same direction but different strokes can be set to control the corresponding CCD cameras 142, so as to detect more positions on the board and achieve better detection results. At the same time, a fine-tuning structure 5 can be set on the fixed plate 113. When the CCD camera 142 detects a gap between the board and the second positioning rod 118, the board is adjusted by the fine-tuning mechanism 5 to achieve a tight fit between the board and the second positioning rod 118.

[0032] Furthermore, such as Figures 5-6As shown, a fixing plate 113 is provided at the bottom of the material support plate 11, and is driven to be connected to the first driving member 13 through the fixing plate 113. A lifting member 114 and several conveyor belts 115 are provided at the top of the fixing plate 113. The lifting member 114 is used to drive the material support plate 11 to move up and down. The material support plate 11 is provided with several lifting ports 116 corresponding to each of the conveyor belts 115. Specifically, before the board enters the feed inlet 12, the support plate 11 is driven to descend by the lifting component 114. At this time, each conveyor belt 115 passes through each lifting port 116, so that the top surface of each conveyor belt 115 is higher than the top surface of the support plate 11. After the board enters the machine box 1 through the feed inlet 12, the bottom surface of the board is conveyed by each conveyor belt 115 and reaches above the support plate 11. The support plate 11 is driven to rise by the lifting component 114 to contact the board, and the bottom surface of the board is separated from the contact of the conveyor belt 115. After being positioned by the positioning mechanism 3, the bottom surface of the board is adsorbed by the suction cup 112 in the opening 111 to achieve the fixing effect of the board.

[0033] Furthermore, such as Figures 5-6As shown, a first positioning rod 117 is provided on one side of the material support plate 11. The positioning mechanism 3 includes a horizontal driving member 31 and a positioning block 32. The horizontal driving member 31 is used to drive the positioning block 32 to push the plate on the material support plate 11 to move, and finally the plate abuts against the first positioning rod 117 for positioning. A second positioning rod 118 is provided on the top surface of the material support plate 11 on the side away from the feed port 12. The first positioning rod 117 and the second positioning rod 118 are perpendicular to each other. Several push rods 321 extend vertically from the bottom of the positioning block 32. The top surface of the material support plate 11 is recessed and provided with movable grooves 119 corresponding to each push rod 321. Specifically, the plate passes through the feed inlet 12 and is transported to the top of the support plate 11 via each conveyor belt 115. The lifting member 114 drives the support plate 11 upwards to contact the plate, separating the bottom surface of the plate from the conveyor belt 115. At this point, one side of the plate abuts against the second positioning rod 118 for positioning, and then the positioning mechanism 3 performs the final positioning. During this process, the horizontal drive member 31 drives the positioning block 32 towards the plate, pushing the plate towards the first positioning rod 117, ultimately positioning one side of the plate against the first positioning rod 117. It is worth noting that the second positioning rod 118 extends vertically, making its height greater than the stroke length of the lifting member 114 driving the support plate 11 to move up and down. This ensures that after the lifting member 114 drives the support plate 11 downwards, the top surface of the conveyor belt 115 is higher than the top surface of the support plate 11. Meanwhile, the top surface of the conveyor belt 115 is lower than the top surface of the second positioning rod 118, so that the conveyor belt 115 conveys the plate to the top of the support plate 11 and continues to convey the plate until one side of the plate abuts against the second positioning rod 118 for positioning, thus achieving the positioning effect. In addition, when the plate is positioned by the positioning mechanism 3, the positioning block 32 is driven by the horizontal drive member 31, and the push rod 321 set at the bottom of the positioning block 32 contacts and pushes the plate to move. Each push rod 321 extends into its corresponding movable groove 119, and the bottom of the push rod 321 does not contact the bottom of the movable groove 119. The bottom of the push rod 321 is lower than the top surface of the support plate 11, so that each push rod 321 can fully contact one side of the plate, preventing the push rod 321 from dislodging from the side of the plate during the process of pushing the plate, and preventing the push rod 321 from being unable to push plates with smaller thicknesses. This has a wide range of applications.

[0034] Furthermore, a transition roller 15 is provided between the inner side of the feed inlet 12 and the support plate 11. Specifically, there is a certain gap between the support plate 11 and the feed inlet 12. By setting the transition roller 15, after the plate enters the feed inlet 12, the bottom surface of the plate first contacts the transition roller 15, and then is captured by each conveyor belt 115 through the transition roller 15. The conveyor belt 115 then transports the plate to the top of the support plate 11, thus avoiding the situation where the plate cannot be captured by the conveyor belt 115 and moved into the gap after entering the feed inlet 12.

[0035] Furthermore, a vacuum pump is connected to the bottom of the suction cup 112.

[0036] Furthermore, such as Figures 7-9As shown, the third driving component 21 includes a fixed guide rail 211, a movable guide rail 212, and a mounting base 213. The fixed guide rail 211 is installed on the top of the housing 1. The top of the fixed guide rail 211 is provided with a first circulating belt 214 and a slide groove 215. The first circulating belt 214 is connected to a first connecting rod 216, which slides in cooperation with the slide groove 215. The top surface of the movable guide rail 212 is slidably connected to the bottom surface of the fixed guide rail 211. A second circulating belt 217 is provided in the middle of the movable guide rail 212, wherein the axial direction of the rollers of the first circulating belt 214 is perpendicular to the axial direction of the rollers of the second circulating belt 217. The movable guide rail 212 is fixedly connected to the bottom end of the first connecting rod 216. The second circulating belt 217 is fixedly installed with the second connecting rod 218. The top end of the second connecting rod 218 extends upward and is fixedly connected to the fixed guide rail 211. The bottom of the mounting base 213 is fixedly installed with the vertical drive component 22. The vertical drive component 22 is connected to the plate picker 221 and drives the plate picker 221 to move vertically. The top surface of the mounting base 213 is slidably connected to the movable guide rail 212. The mounting base 213 has a third connecting rod 219 on the side away from the second connecting rod 218. The third connecting rod 219 is connected to the second circulating belt 217. The first circulating belt 214 is driven by a motor to rotate, and the first connecting rod 216 is driven by the first circulating belt 214 to slide in the slide groove 215, thereby driving the moving guide rail 212 to move closer to or away from the discharge port 2. The second circulating belt 217 is fixedly connected to the inner top wall of the fixed guide rail 211 through the second connecting rod 218. Therefore, when the moving guide rail 212 moves, it drives the first connecting rod 216 to move closer to or away from the second connecting rod 218, and at the same time drives the second circulating belt 217 to rotate. The rotation of the second circulating belt 217 drives the mounting base 213 to move closer to or away from the discharge port 2. When the first circulating belt 214 drives the moving guide rail 212 to move closer to the discharge port 2, it notifies the second circulating belt 217 to rotate and drives the mounting base 213 to move closer to the discharge port 2 through the third connecting rod 219, thereby driving the plate clamp 22 to clamp the plate and transport it out of the discharge port 2. Conversely, the same principle applies. The length of the third driving component 21 is shortened, thereby achieving the effect of reducing the volume of the machine box 1.

[0037] The following is a detailed explanation of the working principle of this utility model;

[0038] In use, the board is fed through the feed port 12 and slid onto the support plate 11. After being positioned by the positioning mechanism 3, the board is attracted by the suction cups 112 in each opening 111. The CCD camera 142 is driven by the second drive unit 14 to take pictures of the contact point between the board and the second positioning rod 118 to identify whether the board and the second positioning rod 118 are tightly attached. After identification, the support plate 11 is driven by the first drive unit 13 to move into the transport position 20 and finally to the bottom of the board picker. The vertical drive unit 22 then drives the board to move further in. The movable plate clamp moves towards the support plate 11 and contacts and clamps the plate on the support plate 11. At this time, the suction cup 112 releases its adsorption on the plate. The vertical drive member 22 drives the plate clamp 221 to lift the plate. The third drive member 21 drives the plate clamp 221 to move outward through the discharge port 12 and transport the plate to the external testing mechanism. The second drive member 14 can drive the CCD camera 142 to move, so as to detect whether one side of the plate is in close contact with the second positioning rod 118, and achieve the recognition effect.
