Description

Technical Field

[0001] This utility model belongs to the field of LED lamp production technology, and in particular relates to a substrate loading robot for LED lamp circuit board production. Background Technology

[0002] LED circuit boards are the core component of LED lamps. They are used to install and connect LED chips and convert electrical energy into current and voltage suitable for LED chips to emit light through circuit design. They are usually made of aluminum substrate or fiberglass board, which not only have good heat dissipation performance and mechanical strength, but also have the advantages of small size, light weight and long life. Because of these advantages, they are widely used in indoor and outdoor lighting, automotive lighting, display screens and other fields.

[0003] The robotic arm is one of the important feeding devices. It uses a clamp to hold the substrate for feeding. The robotic arm and the clamp are usually locked together with multiple bolts. The disassembly process is relatively complicated. When the equipment is maintained, special tools are required to disassemble the clamp and perform maintenance, which affects the progress of equipment maintenance. To address this, we propose a substrate feeding robotic arm for LED circuit board production. Utility Model Content

[0004] The purpose of this invention is to provide a substrate loading robot for LED circuit board production. By incorporating a disassembly component, specifically, an air pump is activated to inject air into an air chamber and air pipe, causing the air chamber to expand and push the insert block outwards to engage with a rectangular protrusion. Then, a threaded pin is inserted to anchor the insert block. After the air chamber releases gas, the insert block retracts into the hollow protrusion under the action of a spring. This allows the operator to easily control the locking of the rectangular top cover and U-shaped base plate by expanding the air chamber. The disassembly process is relatively simple and does not require special tools, ensuring the progress of equipment maintenance. This invention solves the problem that existing robotic arms, which are important loading devices, use clamps to hold substrates for loading. The robotic arm and clamps are usually locked together with multiple bolts, making disassembly complicated. When maintaining the equipment, special tools are needed to disassemble the clamps and perform maintenance, thus affecting the progress of equipment maintenance.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a substrate loading robot for LED lamp circuit board production, including a loading mechanism. The loading mechanism is used to grab or place the substrates needed for processing LED lamps. The loading mechanism includes a robotic arm, a rectangular top cover and a bidirectional lead screw.

[0007] The multi-stage rotation adjustment of the robotic arm is used to displace the substrate it grasps.

[0008] The rectangular top cover is located at the bottom left side of the robotic arm, and a U-shaped base plate is installed at the bottom of the rectangular top cover;

[0009] The bidirectional lead screw is located at the center of the bottom of the U-shaped base plate;

[0010] The rectangular top cover has four hollow protrusions installed on its outer wall, and the four hollow protrusions are arranged in a central circumferential array.

[0011] Furthermore, the feeding mechanism includes a disassembly assembly, which is located at the bottom left side of the robotic arm. The disassembly assembly is used to periodically disassemble and maintain the grippers of the robotic arm.

[0012] A clamping assembly is disposed below the disassembly assembly, and the clamping assembly is used to clamp the processing substrate of the LED lamp from the left and right horizontal directions;

[0013] The inner wall of the bottom of the disassembly component abuts against the outer wall of the clamping component.

[0014] Furthermore, the robotic arm includes eight rectangular protrusions, which are divided into four groups of protrusion assemblies: front, rear, left, and right. The four groups of protrusion assemblies are arranged in a circumferential array with the rectangular top cover as the center. Each group of protrusion assemblies includes two rectangular protrusions, and the outer side walls of the two rectangular protrusions are mounted on the outer wall of the U-shaped base plate. By setting the hollow structure inside the hollow protrusions, the rectangular top cover and the U-shaped base plate can be locked together by setting auxiliary parts such as airbags inside the hollow protrusions.

[0015] The hollow protrusion and the rectangular protrusion are on the same horizontal plane, and the two rectangular protrusions of each protrusion assembly clamp the hollow protrusion from the side with their sides close to each other.

[0016] Furthermore, the hollow protrusion has a hollow center, and an air bladder is installed at the center of the hollow protrusion. Slide plates are provided on both the front and back of the air bladder, and the two slide plates are arranged in a mirror image with the air bladder as the center. By setting the air bladder, when air is injected, it can push the slide plates outward through its own expansion, thereby causing the two slide plates to move away from each other.

[0017] The outer wall of the skateboard and the inner wall of the hollow protrusion are both rounded, so that the outer wall of the skateboard and the inner wall of the hollow protrusion fit together tightly.

[0018] Furthermore, the sides of the two sliding plates that are close to each other are mounted on the outer wall of the airbag, and the sides of the two sliding plates that are far apart are each equipped with an insert. The insert penetrates the hollow protrusion and the rectangular protrusion and extends outward. The insert is shaped as a rounded rectangular protrusion, and its outer diameter matches the inner diameter of the hollow protrusion and the rectangular protrusion at the penetration point. A spring is fitted on the outer side of the outer wall of the insert. A screw hole is opened at the center of the rectangular protrusion, and a threaded pin is threaded into the screw hole of the rectangular protrusion. A shaft passes through the insert and extends downwards. An air pump is installed at the top center of the rectangular top cover. An air chamber is provided on the top of the air pump. The air pump and the air chamber are connected to each other by a hose. Four air pipes are installed on the outer wall of the air chamber. The four air pipes are arranged in a circular array around the air pump. The bottom of each of the four air pipes passes through the top outer wall of the hollow protrusion and extends downwards. The air pipes are connected to the inside of the air bladder. A spring is provided on the outside of the insert so that it can drive the slide plate to return to its original position after the squeezing pressure is removed, thereby pulling the insert out of the rectangular protrusion.

[0019] The outer wall of the skateboard side is flexibly connected to the inner wall of the hollow protrusion by a spring.

[0020] Furthermore, four support blocks are installed at the bottom of the air chamber. All four support blocks are installed at the edge of the outer wall of the bottom of the air chamber and are arranged in a circular array around the air chamber. The circular top cover can provide some protection for the air pump and the air chamber, while the support blocks can provide support for the air chamber from the bottom, preventing the air chamber from accidentally falling downward and damaging the air pump.

[0021] The outer side of the air chamber is fitted with a circular top cover. The inner top wall of the circular top cover is installed on the outer top wall of the air chamber. The bottom of the circular top cover has four notches. The top of the circular top cover is connected to the bottom left side of the robotic arm.

[0022] Furthermore, the clamping assembly includes two clamping plates, which are respectively sleeved on the left and right sides of the outer wall of the bidirectional lead screw. Each clamping plate has an internal thread at its center and is threaded to the outer wall of the bidirectional lead screw. The left and right sides of the bidirectional lead screw extend outwards through the outer wall of the U-shaped base plate and are rotatably connected. A motor is located on the left side of the bidirectional lead screw and is mounted on the left outer wall of the U-shaped base plate. The coupling at the output end of the motor on the right side is mounted on the left outer wall of the bidirectional lead screw. The clamping plates are trapezoidal in shape. Three arc-shaped protrusions are installed on the bottom of each plate on the side closest to each other. A support ring is sleeved on the outer side of the outer wall of the center of the bidirectional lead screw. The support ring is installed on the inner wall of the top of the U-shaped base plate. Four slide rails are provided on the outer side of the bidirectional lead screw. The four slide rails are arranged in a circular array with the bidirectional lead screw as the center. The slide rails pass through the two clamping plates and are slidably connected. The left and right outer walls of the slide rails are installed on the inner wall of the U-shaped base plate. By setting the opposite external threads on both sides of the bidirectional lead screw, the bidirectional lead screw can be controlled to make the two clamping plates move closer or further apart by controlling its rotation direction.

[0023] The slide rail is designed with a square hole, and the threads on the left and right sides of the outer wall of the bidirectional lead screw are mirror images of each other with the support ring as the center.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model, through the setting of a disassembly component, specifically involves starting an air pump to inject air into the airbag through the air chamber and air pipe, causing the airbag to expand and push the insert block outward to displace and engage with the rectangular protrusion. Then, a threaded pin is inserted to anchor the insert block. In this way, after the airbag discharges the gas, the insert block retracts into the hollow protrusion under the action of the spring. This allows the operator to control the locking of the rectangular top cover and the U-shaped bottom plate by expanding the airbag. The disassembly steps are relatively simple and do not require the use of special tools, ensuring the progress of equipment maintenance.

[0026] 2. This utility model sets up a clamping assembly, specifically by starting a motor to rotate a bidirectional lead screw, and by using the opposite external threads of the bidirectional lead screw to bring two clamping plates closer to each other along the slide rail, and by using the arc-shaped protrusions installed at the bottom of the clamping plates to clamp the LED substrate. In this way, the substrate can be quickly connected to the clamping assembly, which facilitates the robotic arm to adjust the spatial displacement of the substrate and ensures that the robotic arm can stably perform the LED substrate loading work.

[0027] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The loading mechanism 1 includes a disassembly assembly 12, which is located at the bottom left side of the robotic arm 11. The disassembly assembly 12 is used to periodically disassemble and maintain the grippers of the robotic arm 11. The clamping assembly 13 is located below the disassembly assembly 12 and is used to clamp the processing substrate of the LED light from the left and right horizontal directions. The bottom inner wall of the disassembly assembly 12 abuts against the outer wall of the clamping assembly 13. The robotic arm 11 includes eight rectangular protrusions 1222. The eight rectangular protrusions 1222 are divided into four groups of protrusion components: front, rear, left, and right. The four groups of protrusion components are arranged in a circular array with the rectangular top cover 1211 as the center. Each group of protrusion components includes two rectangular protrusions 1222.

The hollow protrusion 1221 and the rectangular protrusions 1222 are on the same horizontal plane.

The air tubes 128 are arranged in a circular array around the air pump 1261. The bottoms of the four air tubes 128 all penetrate the top outer wall of the hollow protrusion 1221 and extend downwards. The air tubes 128 are interconnected with the inside of the airbag 123. When the air pump 1261 is activated, air is injected into the airbag 123 through the air chamber 1262 and the air tubes 128, causing the airbag 123 to inflate and push the insert 1242 outwards to engage with the rectangular protrusion 1222. Then, the threaded pin 125 is inserted to engage the insert 1242. 2. Anchoring: After the airbag 123 discharges the gas, the insert 1242 retracts into the hollow protrusion 1221 under the action of the spring. This allows the operator to control the locking of the rectangular top cover 1211 and the U-shaped base plate 1212 by expanding the airbag 123. The disassembly steps are relatively simple and do not require special tools, ensuring the progress of equipment maintenance. The outer wall of the side of the slide plate 1241 and the inner wall of the hollow protrusion 1221 are flexibly connected by springs. Four support blocks 127 are installed at the bottom of the air chamber 1262. The four support blocks 127 are all installed at the edge of the bottom outer wall of the air chamber 1262 and are arranged in a circular array with the air chamber 1262 as the center. A circular top cover 129 is fitted on the outside of the air chamber 1262. The inner wall of the top of the circular top cover 129 is installed on the outer wall of the top of the air chamber 1262. Four notches are opened at the bottom of the circular top cover 129. The top of the circular top cover 129 is connected to the bottom left side of the robotic arm 11.The clamping assembly 13 includes two clamping plates 132, which are respectively fitted onto the left and right sides of the outer wall of the bidirectional lead screw 131. Each clamping plate 132 has an internal thread at its center. The clamping plates 132 are threadedly connected to the outer wall of the bidirectional lead screw 131. The left and right sides of the bidirectional lead screw 131 extend outwards through the outer wall of the U-shaped base plate 1212 and are rotatably connected. A motor 134 is located on the left side of the bidirectional lead screw 131 and is mounted on the left outer wall of the U-shaped base plate 1212. The coupling at the right output end of the motor 134 is mounted on the left outer wall of the bidirectional lead screw 131. The clamping plates 132 are trapezoidal in shape. Three arc-shaped protrusions 133 are installed at the bottom of the two clamping plates 132 on their closest sides. A support ring 135 is fitted onto the outer side of the outer wall at the center of the bidirectional lead screw 131 and is mounted on the top inner wall of the U-shaped base plate 1212. There are four slide rails 136, which are arranged in a circular array around the bidirectional lead screw 131. The slide rails 136 pass through the two clamping plates 132 and are slidably connected. The left and right outer walls of the slide rails 136 are installed on the inner wall of the U-shaped base plate 1212. The motor 134 is started to rotate the bidirectional lead screw 131, and the two clamping plates 132 are brought closer to each other along the slide rails 136 through the opposite external threads of the bidirectional lead screw 131. The LED substrate is clamped by the arc protrusions 133 installed at the bottom of the clamping plates 132. In this way, the substrate can be quickly connected to the clamping assembly 13, which facilitates the spatial displacement adjustment of the substrate by the robotic arm 11 and ensures that the robotic arm 11 can stably perform the LED substrate loading work. The slide rails 136 are square holes. The threads on the left and right sides of the outer wall of the bidirectional lead screw 131 are mirrored with the support ring 135 as the center.

[0038] One specific application of this embodiment is as follows: When in use, the robotic arm 11 is first started to put the robotic arm 11 into working state. The model of the robotic arm 11 is FANUC M-1000iA. The robotic arm 11 identifies the location of the LED substrate through a sensor or vision system, and then moves the disassembly assembly 12 above the LED substrate through the robotic arm 11.

[0039] Next, the motor 134 is started to rotate the bidirectional lead screw 131. When the bidirectional lead screw 131 rotates, it will drive the two clamping plates 132 to move closer to each other through the opposite external threads on both sides of the outer surface. When the clamping plates 132 move, they will move along the slide rail 136 to clamp the LED substrate in the hopper from the left and right sides. Then the robotic arm 11 is started again to move the LED substrate clamped by the clamping assembly 13 to the production line for subsequent production.

[0040] When the equipment has been in use for a long time, internal wear will occur, affecting its working performance. Internal maintenance is required, including replacing worn parts. The threaded pin 125 is rotated and pulled out. Then, the air pump 1261 is started to draw air from the airbag 123 into the air chamber 1262. Air is then drawn into the air pump 1261 through the hose between the air pump 1261 and the air chamber 1262, and finally expelled, causing the airbag 123 to gradually shrink and return to its original shape. The sliding surfaces on both sides of the airbag 123... After the plate 1241 is released from pressure, it will retract into the hollow protrusion 1221 under the action of the spring, and pull out the insert 1242 from the through point of the rectangular protrusion 1222, thus ending the locking between the rectangular top cover 1211 and the U-shaped bottom plate 1212. Then, the U-shaped bottom plate 1212 is removed for maintenance of its bottom parts. Then, the rectangular top cover 1211 and the U-shaped bottom plate 1212 are aligned, and then the air pump 1261 is started to relock the rectangular top cover 1211 and the U-shaped bottom plate 1212 together.

The four slide rails (136) are arranged in a circular array with the bidirectional lead screw (131) as the center. The slide rails (136) pass through the two clamping plates (132) and are slidably connected. The left and right outer walls of the slide rails (136) are installed on the inner wall of the U-shaped base plate (1212). The slide rail (136) is designed with a square hole, and the threads on the left side of the outer wall of the bidirectional lead screw (131) and the threads on the right side of the outer wall of the bidirectional lead screw (131) are mirrored with the support ring (135) as the center.
