Description

Technical Field

[0001] This invention relates to the technical field of circuit board storage, and more particularly to a circuit board storage rack and unloading method. Background Technology

[0002] With the continuous development of the electronics industry, resin vacuum via plugging technology for PCB circuit boards, which serve as carriers for electronic products, is increasingly being applied to more and more circuit boards. Furthermore, in the production process, to make PCB circuit boards more suitable for various electronic products and to allow them to play a greater role, it is necessary to continuously optimize and improve the process flow. In the fully automated via plugging process, circuit board storage racks are essential as a preparatory step before plugging. PCBs are stacked on the storage racks for easy retrieval by robotic arms. However, directly stacking circuit boards on the racks can easily cause scratches between them. If spacers are placed between the circuit boards, the spacers must be removed after each board is taken by the robotic arm before the next board can be retrieved.

[0003] Currently, the China Patent Network has published a novel anti-scratch screen printing stencil holder for circuit boards with announcement number CN217470397U. It includes a lower frame and an upper frame spaced apart, both of which are hollow tubular square frames. Support rods are installed at the four corners of the upper surface of the lower frame and the lower surface of the upper frame. Evenly distributed fixing rods are installed on the inner sides of the lower and upper frames. Bearings are fitted onto the ends of the fixing rods near the lower and upper frames, and rollers are fitted onto the outside of the bearings. A baffle is threaded between the upper surfaces of the lower and upper frames. A U-shaped rod is installed on the lower surface of the upper frame corresponding to the baffle. Embedding holes are formed on the upper surfaces of the lower and upper frames corresponding to the baffles.

[0004] The aforementioned patent has the following defects:

[0005] Because the circuit board screen printing stencil is vertically inserted between the baffles between the lower and upper frames, and is arranged longitudinally in the horizontal direction, it not only occupies a large area, but also makes it difficult for the robotic arm to pick up the circuit board due to the obstruction of the support rod. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] In view of the problems of existing circuit board storage racks having a large footprint and being inconvenient for robotic arms to handle circuit boards, this invention is proposed.

[0008] Therefore, the purpose of this invention is to provide a circuit board storage rack and unloading method, which aims to reduce the floor space occupied by the circuit boards during storage and facilitate the handling of the circuit boards by a robotic arm.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0012] As a preferred embodiment of the circuit board storage rack of the present invention, the pressing assembly includes a first spring disposed at the center of the bottom of the storage plate, a pressure plate disposed at the other end of the first spring, and a ball bearing disposed at the lower end of the pressure plate, wherein the ball bearing is rotatably connected to the upper end of the circuit board body.

[0013] As a preferred embodiment of the circuit board storage rack of the present invention, the pressing assembly includes a limiting groove symmetrically arranged at the bottom of the storage plate about the first spring, and a limiting rod with one end inserted into the limiting groove, and the other end of the limiting rod passing through the opening of the limiting groove and connected to the upper end of the pressure plate. The storage component also includes a fixing assembly arranged on the storage tank. The fixing assembly includes a fixing frame symmetrically connected to the opening of the storage tank about the circuit board body, a fixing plate rotatably arranged on the fixing frame, and the fixing plate is movably arranged on the edge of the circuit board body, torsion springs arranged on both sides of the fixing plate, and a fixing ring arranged on the other side of the torsion spring, and the fixing ring is fixedly sleeved on the fixing frame.

[0014] As a preferred embodiment of the circuit board storage rack of the present invention, the discharge component includes a first conveyor belt disposed at the lower end of the storage component, a storage plate cover disposed at the upper end of the first conveyor belt, and the storage plate is disposed inside the storage plate cover. The bottom storage plate is disposed on the belt of the first conveyor belt, a pusher assembly disposed on the storage plate, and a discharge component disposed on the storage plate cover.

[0015] As a preferred embodiment of the circuit board storage rack of the present invention, the pusher assembly includes an arc-shaped plate disposed on both sides of the pressure plate, and the pressure plate and the arc-shaped plate are integrally formed. The bottom of the storage plate is provided with a receiving groove corresponding to the position of the arc-shaped plate, and a pusher block is disposed on the upper edge of the storage plate. The cross-section of the pusher block is a right-angled trapezoid, and the inclined surface of the pusher block is set towards the arc-shaped plate.

[0016] As a preferred embodiment of the circuit board storage rack of the present invention, the discharge assembly includes discharge ports disposed on both sides of the bottom of the storage plate cover, an arc-shaped rubber strip connected to the top of the discharge port near the discharge end of the first conveyor belt, and a push plate disposed on the first conveyor belt.

[0017] As a preferred embodiment of the circuit board storage rack of the present invention, the discharge end of the discharge component is provided with a stopping component; the stopping component includes a second conveyor belt disposed at the discharge end of the first conveyor belt, a support frame disposed directly below the second conveyor belt, a second spring disposed between the second conveyor belt and the support frame, and a conductive component disposed between the second conveyor belt and the support frame.

[0018] As a preferred embodiment of the circuit board storage rack of the present invention, the conductive component includes a support rod disposed at the lower end of the second conveyor belt, the support rod movably passing through the support frame and connected to a support block, a conductive block disposed at the lower end of the support block, conductive wheels disposed on both sides of the conductive block, conductive seats symmetrically disposed at the lower end of the support frame about the support block, and conductive strips disposed on the conductive seats, and the conductive wheels are rotatably connected to the corresponding conductive strips, the second conveyor belt, conductive block, conductive wheels and conductive strips are electrically connected by wires.

[0019] The beneficial effects of this invention are as follows: the circuit board body is fixed in the storage plate and stacked, which reduces the space occupied by the storage component. At the same time, the adjacent circuit board bodies are separated by the storage plate to avoid scratches between the circuit board bodies. The storage plate is fed out in order from bottom to top. When the robot arm grasps it, the circuit board body remains stationary, which improves the stability of the grasping process and avoids errors. Moreover, the second conveyor belt does not work during the grasping process, which reduces energy consumption.

[0020] Another objective of this invention is to provide a method for unloading circuit board storage racks, which aims to avoid scratches between circuit board bodies and improve the stability of the robotic arm during the gripping process.

[0021] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a method for unloading circuit board storage racks, comprising the following steps,

[0022] The circuit board body is placed into the storage tank inside the storage plate, and the circuit board body is wrapped and protected by the buffer bag inside the storage tank.

[0023] Then, stack the storage plates into the storage plate cover, and the pressure plate squeezes the first spring and presses it onto the circuit board body;

[0024] Start the first conveyor belt. The belt of the first conveyor belt drives the push plate to move. The push plate contacts and pushes the bottom storage plate. When the storage plate moves, it drives the push block on itself to move synchronously.

[0025] When the bottom storage plate passes through the discharge port, the pusher block contacts the arc plate, pushing the arc plate and the pressure plate upward, compressing the first spring;

[0026] When the storage plate detaches from the storage plate cover, the storage plate above it naturally falls onto the belt of the first conveyor belt and stops directly below the storage plate cover.

[0027] The storage plate, detached from the storage cover, is gradually conveyed onto the second conveyor belt via the first conveyor belt. The pressure on the second spring gradually increases, causing the conductive wheel to roll on the conductive strip, maintaining power to the second conveyor belt until the storage plate is completely transported onto the second conveyor belt. At this point, the conductive wheel disengages from the conductive strip, the second conveyor belt is de-energized, and the storage plate and circuit board body remain stationary. The robotic arm then removes the circuit board body from the storage plate, the pressure on the second spring decreases and resets, the conductive wheel re-engages with the conductive strip, and the second conveyor belt is energized again, moving the storage plate away from the second conveyor belt.

[0028] The beneficial effects of this method are: avoiding scratches between circuit boards, reducing the space required for storage, improving the stability of the robotic arm during the grasping process, and reducing energy consumption. Attached Figure Description

[0048] Example 1

[0049] Reference Figure 1-4 The first embodiment of the present invention provides a circuit board storage rack. This device includes a robotic arm (not shown in the figure), and a storage unit 1000 is provided below the robotic arm. The storage unit 1000 includes a storage component 1100 and a discharge component 1200 installed outside the storage component 1100. The discharge component 1200 can be a discharge box to protect the storage component 1100.

[0050] The storage component 1100 includes multiple storage plates 1110 stacked vertically, four rollers 1120 mounted on both sides of the storage plates 1110, a storage trough 1130 formed on the storage plates 1110, a buffer bladder 1140 connected to the storage trough 1130, a circuit board body 1150 placed on the buffer bladder 1140, and a clamping assembly 1160 installed between any two adjacent storage plates 1110; the clamping assembly 1160 includes a first spring 1161 connected to the center of the bottom of the storage plates 1110. In a compressed state, a pressure plate 1162 is connected to the other end of the first spring 1161, and a plurality of balls 1163 are embedded in the lower end of the pressure plate 1162. The balls 1163 are tumblingly connected to the upper end of the circuit board body 1150. The balls 1163 press against the upper end of the circuit board body 1150 to press and fix the upper end of the circuit board body 1150. When the upper end of the circuit board body 1150 moves relative to the pressure plate 1162, the balls 1163 roll on the upper end of the circuit board body 1150 to avoid friction between the pressure plate 1162 and the circuit board body 1150.

[0051] The storage plate 1110 has two limiting grooves 1164 symmetrically provided at the bottom about the first spring 1161, and a limiting rod 1165 with one end inserted in the limiting groove 1164. The other end of the limiting rod 1165 passes through the opening of the limiting groove 1164 and is connected to the upper end of the pressure plate 1162. Since the limiting rod 1165 can only move in the limiting groove 1164, the movement direction of the pressure plate 1162 is limited.

[0052] During use, the circuit board body 1150 is placed inside the buffer bladder 1140, and the first spring 1161 pushes the pressure plate 1162 downward to apply pressure to the circuit board body 1150, fixing the circuit board body 1150 in the buffer bladder 1140 inside the storage tank 1130. The circuit board bodies 1150 are stacked vertically, reducing the space occupied by the storage component 1100. Adjacent circuit board bodies 1150 are separated by the storage plate 1110 to prevent scratches between the circuit board bodies 1150.

[0053] Example 2

[0054] Reference Figure 1-6 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the discharge component 1200 includes a first conveyor belt 1210 disposed at the lower end of the storage component 1100, a storage plate cover 1220 installed at the upper end of the first conveyor belt 1210, a cover can be installed on the top opening of the storage plate cover 1220, and the cover is placed on the storage plate cover 1220 when the equipment is not in use to prevent dust from entering. The front of the storage plate cover 1220 is also equipped with a door, which can be opened to stack the storage plates 1110, and the storage plates 1110 are disposed inside the storage plate cover 1220. The bottom storage plate 1110 is placed on the belt of the first conveyor belt 1210, a pusher component 1230 is installed on the storage plate 1110, and a discharge component 1240 is installed on the storage plate cover 1220.

[0055] The feeding assembly 1230 includes arc-shaped plates 1231 symmetrically connected to the two sides of the pressure plate 1162, and the pressure plate 1162 and the arc-shaped plates 1231 are integrally formed. The bottom of the storage plate 1110 is provided with a receiving groove 1232 corresponding to the position of the arc-shaped plates 1231. When the pressure plate 1162 drives the arc-shaped plates 1231 to rise, the arc-shaped plates 1231 are stored through the receiving groove 1232. The assembly also includes a push block 1233 connected to the upper edge of the storage plate 1110. The push block 1233 has a right-angled trapezoidal cross section, and the inclined surface of the push block 1233 faces the direction of the pressure plate 1162. The arc-shaped plate 1231 is provided; the discharge assembly 1240 includes discharge ports 1241 provided on both sides of the bottom of the storage plate cover 1220, and an arc-shaped rubber strip 1242 is connected to the top of the discharge port 1241 near the discharge end of the first conveyor belt 1210, and a push plate 1243 is connected to the belt of the first conveyor belt 1210. Before the push plate 1243 applies a pushing force to the storage plate 1110, the rubber strip 1242 blocks the bottom storage plate 1110, and the roller 1120 on the storage plate 1110 rotates on the first conveyor belt 1210.

[0056] During use, the storage plates 1110 containing the circuit board body 1150 are stacked inside the storage plate cover 1220. When the first conveyor belt 1210 starts, the belt of the first conveyor belt 1210 drives the pusher plate 1243 to move to the side of the bottom storage plate 1110, applying a pushing force to the bottom storage plate 1110. The storage plate 1110 pushes the rubber strip 1242 to deform and pass through the discharge port 1241. When the storage plate 1110 moves, it drives the pusher block 1233 to move synchronously. When the pusher block 1233 contacts the arc plate 1231... When touched, the arc plate 1231 is pushed to drive the pressure plate 1162 to compress the first spring 1161 and move upward, so that the push block 1233 can move normally until the push block 1233 squeezes the rubber strip 1242 through the discharge port 1241. When the bottom storage plate 1110 moves out of the storage plate cover 1220, the storage plate 1110 above the storage plate 1110 naturally falls onto the belt of the first conveyor belt 1210, and is pressed by the pressure plate 1162 to prevent the circuit board body 1150 from jumping and colliding in the storage tank 1130.

[0057] The remaining structure is the same as that in Example 1.

[0058] Example 3

[0059] Reference Figure 1-8This is the third embodiment of the present invention, which differs from the second embodiment in that: the discharge end of the discharge component 1200 is provided with a stopping component 1300; the stopping component 1300 includes a second conveyor belt 1310 disposed at the discharge end of the first conveyor belt 1210, with a robotic arm positioned above the second conveyor belt 1310 to grasp the circuit board body 1150 on the second conveyor belt 1310, a support frame 1320 disposed directly below the second conveyor belt 1310, multiple second springs 1330 connected between the second conveyor belt 1310 and the support frame 1320, the second springs 1330 being replaced periodically, and a conductive component 1340 installed between the second conveyor belt 1310 and the support frame 1320. Component 1340 includes a support rod 1341 connected to the center of the lower end of the second conveyor belt 1310, and the support rod 1341 movably passes through the support frame 1320 and is connected to a support block 1342. The support block 1342 is made of insulating material. A conductive block 1343 is connected to the lower end of the support block 1342. Conductive wheels 1344 are symmetrically connected to both sides of the conductive block 1343. A conductive seat 1345 is symmetrically connected to the lower end of the support frame 1320 about the support block 1342. A conductive strip 1346 is installed on the conductive seat 1345. The conductive wheel 1344 is rotatably connected to the corresponding conductive strip 1346. The second conveyor belt 1310, the conductive block 1343, the conductive wheel 1344 and the conductive strip 1346 are electrically connected by wires.

[0060] During operation, the first conveyor belt 1210 transports the storage plate 1110 containing the circuit board body 1150 onto the second conveyor belt 1310. As more of the storage plate 1110 is transported onto the second conveyor belt 1310, the weight on the second conveyor belt 1310 increases. Simultaneously, the second conveyor belt 1310 compresses the second spring 1330 and pushes the support block 1342, conductive block 1343, and conductive wheel 1344 downwards via the support rod 1341. The conductive wheel 1344 rolls on the conductive strip 1346. When the storage plate 1110 containing the circuit board body 1150 is completely transported onto the second conveyor belt 1310, the conductive wheel 1344 disengages from the conductive strip 1346, the second conveyor belt 1310 is de-energized and stops working, and the storage plate 1110 containing the circuit board body 1150 is moved to the second conveyor belt 1310. The robot arm remains stationary on conveyor belt 1310. Then, it grabs the circuit board body 1150 from storage plate 1110. Once the circuit board body 1150 detaches from storage plate 1110, the second spring 1330 experiences reduced gravity and partially resets, pushing the second conveyor belt 1310 upwards. This causes the conductive wheel 1344 to re-engage with the conductive strip 1346, resuming power supply to the second conveyor belt 1310. The second conveyor belt 1310 restarts operation, conveying the storage plate 1110 from which the robot arm has taken the circuit board body 1150. During the robot arm's grabbing of the circuit board body 1150, the circuit board body 1150 remains stationary, improving stability and preventing errors. Furthermore, the second conveyor belt 1310 does not operate during the grabbing process, reducing energy consumption.

[0061] The remaining structure is the same as that in Example 2.

[0062] Example 4

[0063] Reference Figure 1-9 This is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that the storage component 1100 further includes a fixing component 1170 installed on the storage tank 1130. The fixing component 1170 includes a fixing frame 1171 symmetrically connected to the opening of the storage tank 1130 with respect to the circuit board body 1150, a fixing plate 1172 rotatably connected to the fixing frame 1171 and the fixing plate 1172 is movably pressed on the edge of the circuit board body 1150, torsion springs 1173 connected to both sides of the fixing plate 1172 and the torsion springs 1173 are sleeved on the fixing frame 1171, and a fixing ring 1174 connected to the other side of the torsion springs 1173 and the fixing ring 1174 is fixedly sleeved on the fixing frame 1171.

[0064] During use, when installing the circuit board body 1150 into the storage plate 1110, first apply an upward pushing force to the fixing plate 1172 on one side of the storage plate 1110. When the fixing plate 1172 rotates on the fixing frame 1171, it applies force to the torsion spring 1173, causing the torsion spring 1173 to deform, placing one side of the circuit board body 1150 into the buffer bladder 1140. Then, release the fixing plate 1172. Under the action of the restoring force of the torsion spring 1173, the fixing plate 1172 presses on one side edge of the circuit board body 1150. Then apply an upward pushing force to the fixing plate 1172 on the other side, placing the other side of the circuit board body 1150 into the buffer bladder 1140. Release the fixing plate 1172 on that side. Under the action of the restoring force of the torsion spring 1173, the fixing plate 1172 presses on the other side edge of the circuit board body 1150, improving the fixing effect of the circuit board body 1150.

[0065] When the robotic arm grasps the circuit board body 1150, it applies an upward pulling force to the circuit board body 1150. The edges of the circuit board body 1150 apply an upward pushing force to the fixing plate 1172. The fixing plate 1172 applies force to the torsion spring 1173, causing the torsion spring 1173 to deform. At the same time, the fixing plate 1172 rotates upward on the fixing frame 1171, so that the circuit board body 1150 can be normally separated from the storage plate 1110.

[0066] The remaining structure is the same as that in Example 3.

[0067] Example 5

[0068] Reference Figure 1-9 The fifth embodiment of the present invention provides a method for unloading circuit board storage racks, comprising the following steps:

[0069] S1: Open the fixing plates 1172 on both sides of the storage tank 1130, and put the circuit board body 1150 into the storage tank 1130 in the storage plate 1110. The circuit board body 1150 is wrapped and protected in the storage tank 1130 by the buffer bag 1140 and fixed by the fixing plate 1172.

[0070] S2: Then stack the storage plates 1110 into the storage plate cover 1220, and press the pressure plate 1162 squeezes the first spring 1161 and presses it onto the circuit board body 1150.

[0071] S3: Start the first conveyor belt 1210. The belt of the first conveyor belt 1210 drives the push plate 1243 to move. The push plate 1243 contacts and pushes the bottom storage plate 1110. When the storage plate 1110 moves, it drives the push block 1233 on itself to move synchronously.

[0072] S4: When the bottom storage plate 1110 passes through the discharge port 1241, the push block 1233 contacts the arc plate 1231, pushing the arc plate 1231 and the pressure plate 1162 to move upward, compressing the first spring 1161;

[0073] S5: When the storage plate 1110 is removed from the storage plate cover 1220, the storage plate 1110 located above the storage plate 1110 naturally falls onto the belt of the first conveyor belt 1210 and stops directly below the storage plate cover 1220.

[0074] S6: The storage plate 1110, detached from the storage plate cover 1220, is gradually conveyed onto the belt of the second conveyor belt 1310 via the first conveyor belt 1210. The pressure on the second spring 1330 gradually increases, causing the conductive wheel 1344 to roll on the conductive strip 1346, maintaining power to the second conveyor belt 1310 until the storage plate 1110 is completely transported onto the belt of the second conveyor belt 1310. At this point, the conductive wheel 1344 disengages from the conductive strip 1346, and the second conveyor belt 1310... 10. When the power is cut off, the storage plate 1110 and the circuit board body 1150 remain in place. The robot then picks up the circuit board body 1150 from the storage plate 1110. The circuit board body 1150 pushes open the fixing plate 1172 and moves out of the storage plate 1110. The pressure on the second spring 1330 decreases and it resets a certain distance.
