Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically a flipping machine for circuit board production. Background Technology

[0002] In the production and testing of printed circuit boards, there are usually conveyor belts for transporting printed circuit boards. Since most printed circuit boards are double-sided, both sides must be processed during production and testing. During the production of circuit boards, there will be some waste material on the surface, which needs to be removed and collected. A flipping machine for circuit board production is needed to process the waste material on the surface of the circuit boards.

[0003] Existing flipping machines have low operating efficiency, and the waste material is inconvenient to collect after being knocked off. They are also inconvenient for flipping circuit boards of different sizes, making it difficult for users to adjust the position of the adjustment plate and reducing the machine's versatility. Furthermore, existing flipping machines are not stable enough when clamping the circuit board surface, failing to securely hold the board during flipping and providing no protection against damage. In addition, existing flipping machines are inconvenient for collecting waste material from the circuit board surface, making them difficult for users to operate. Utility Model Content

A first lead screw nut is threaded on the surface of the first lead screw body, and the first lead screw nut is slidably engaged with the inner wall of the fixed frame. The surface of the first lead screw nut is fixed to the surface of the frame. Guide rods are installed on the inner wall of the fixed frame, and the guide rods are slidably engaged with the surface of the frame. Grooves are formed on the surface of the fixed plate.

[0007] Preferably, the waste recycling mechanism consists of a guide block, a door, a cavity, a collection frame, and an elastic clip. The inside of the housing is provided with a cavity, and a collection frame for collecting waste is provided inside the cavity. Guide blocks are installed on both sides of the collection frame, and the guide blocks slide against the inner wall of the cavity.

[0008] Preferably, the bottom surface of the collection frame is equipped with elastic clips, which engage with the inner wall of the chassis. The collection frame is located below the guide frame, and the surface of the chassis is provided with a door, which is detachably connected to the surface of the chassis.

[0009] Preferably, the stabilizing clamping mechanism consists of a cylinder, a first clamping plate, a sponge pad, a groove, and a second clamping plate. Cylinders are installed on the surface of the flipping plate. The input end of the cylinder is electrically connected to the output end of the controller. The second clamping plate is installed on the surface of the clamping frame.

[0010] Preferably, the surface of the fixture frame is provided with a first clamping plate, and the surfaces of the first clamping plate and the second clamping plate are both equipped with sponge pads for surface protection of the circuit board body. The surface of the fixture frame is provided with a groove, and the groove slides and engages with the surface of the first clamping plate.

[0011] Preferably, the convenient adjustment mechanism consists of a fixed rod, a servo motor body, a shaft, a second lead screw body, and a second lead screw nut. The surface of the chassis is provided with a second lead screw body. One end of the second lead screw body passes through the adjustment plate and rotates with the inner wall of the fixed plate. The surface of the second lead screw body is threaded with a second lead screw nut. The surface of the second lead screw nut is fixed to the inner wall of the adjustment plate, and the second lead screw nut slides with the surface of the chassis.

[0012] Preferably, a servo motor body is installed on the inner wall of the chassis. The input end of the servo motor body is electrically connected to the output end of the controller. A shaft is installed on the output end of the servo motor body through a coupling. One end of the shaft is fixed to the surface of the second lead screw body. Fixing rods are installed on the inner walls of both the chassis and the fixing plate. The fixing rods slide against the surface at the bottom of the adjusting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the flipping machine not only makes it convenient for users to adjust the position of the adjustment plate, making the flipping machine more versatile, but also allows the flipping machine to firmly clamp the circuit board body for flipping, and at the same time, it can protect the surface of the circuit board body from damage. In addition, the flipping machine can collect the waste material on the surface of the circuit board body for processing, making the flipping machine more convenient for users to operate.

[0014] 1. By setting up a convenient adjustment mechanism, the servo motor body inside the control box is controlled to work. Under the action of the servo motor body, the shaft body is driven to rotate. When the shaft body rotates, the shaft body drives the second lead screw body to rotate on the inner wall of the fixed plate. Under the joint action of the second lead screw body and the second lead screw nut, the second lead screw nut moves on the surface of the second lead screw body, thereby driving the adjustment plate to move on the surface of the control box. At this time, the adjustment plate slides on the surface of the fixed rod. Under the action of the fixed rod, the adjustment plate is guided to avoid the phenomenon of the adjustment plate being tilted when adjusting the position. This realizes the function of flipping the circuit board body of different sizes, so that the user can easily adjust the position of the adjustment plate when using the flipping machine, making the flipping machine more versatile in use.

[0015] 2. By setting up a stable clamping mechanism, when the controller controls the cylinder to work, the cylinder drives the first clamping plate to move on the surface of the clamp frame, so that the first clamping plate slides inside the groove. Under the action of the groove, the first clamping plate is guided, so that the first clamping plate moves downward until it contacts the surface of the circuit board body. Under the combined action of the groove and the first clamping plate, the surface of the circuit board body is clamped by the groove, which prevents the circuit board body from shaking when flipping and hitting. With the action of the sponge pad, the surface of the circuit board body can be protected and protected from damage. This realizes the function of the flipping machine to stably clamp the surface of the circuit board body, so that the flipping machine can stably clamp the circuit board body for flipping, and at the same time, it can protect the surface of the circuit board body from damage.

[0016] 3. Equipped with a waste recycling mechanism, waste falls into the guide frame and automatically descends into the collection frame under gravity. The collection frame collects the waste. To process the waste inside the collection frame, the user pulls the door on the surface of the machine housing. Then, the user pulls the collection frame inside the cavity, causing the guide block to slide against the inner wall of the machine housing. The guide block guides the collection frame, causing the elastic clip to move away from the inner wall of the machine housing, thus collecting the waste inside the collection frame. This achieves the function of centralized waste collection for the flipping machine, allowing it to collect waste from the surface of the circuit board for processing, making the flipping machine more convenient for users.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0024] This utility model provides a structure for a flipping machine used in circuit board production, as shown in the following figure. Figure 1 and Figure 2 As shown, the system includes a chassis 1, on the surface of which a controller 101 (e.g., LA series) is mounted. A mounting plate 103 is mounted on the top surface of the chassis 1. An adjustment plate 102 is also mounted on the surface of the chassis 1. A mounting bracket 104 is mounted on the top surface of the chassis 1. Inside the mounting bracket 104 is a flip-up plate 108. A clamping frame 116 is mounted on the surface of the flip-up plate 108 using screws. A photoelectric sensor 109 (e.g., E series) is mounted on the surface of the flip-up plate 108. The input terminal of the photoelectric sensor 109 is electrically connected to the output terminal of the controller 101. Inside the mounting bracket 104 is a first lead screw body 107, which rotatably engages with the inner wall of the mounting bracket 104. Inside the mounting bracket 104 is a frame 114, inside which is installed a rotary motor 115. The rotary motor 115 can be a JO series model. The input end of the rotary motor 115 is electrically connected to the output end of the controller 101. The output end of the rotary motor 115 is equipped with a rotating shaft through a coupling, and one end of the rotating shaft is fixed to the surface at the center of the flip plate 108. The surface of the first lead screw body 107 is threaded with a first lead screw nut 113. The first lead screw nut 113 slides with the inner wall of the fixed frame 104. The surface of the first lead screw nut 113 is fixed with the surface of the frame 114. The inner wall of the fixed frame 104 is equipped with guide rods 112. The guide rods 112 slide with the surface of the frame 114. The surface of the fixed plate 103 is provided with grooves 110. The inside of the machine box 1 is equipped with a guide frame 105. The inner walls of the adjusting plate 102 and the fixed plate 103 are provided with conveying components 106. The surface of the conveying components 106 is provided with a circuit board body 111.

[0025] Furthermore, such as Figure 2 As shown, the interior of the chassis 1 is equipped with a waste recycling mechanism 2, which consists of a guide block 21, a door 22, a cavity 23, a collection frame 24, and an elastic clip 25. The interior of the chassis 1 has a cavity 23, and the cavity 23 is equipped with a collection frame 24 for collecting waste. Guide blocks 21 are installed on both sides of the collection frame 24, and the guide blocks 21 slide against the inner wall of the cavity 23. Elastic clips 25 are installed on the bottom surface of the collection frame 24, and the elastic clips 25 engage with the inner wall of the chassis 1. The collection frame 24 is located below the guide frame 105. The surface of the chassis 1 is equipped with a door 22, which is detachably connected to the surface of the chassis 1.

[0026] During implementation, after the waste falls into the guide frame 105, it automatically falls into the collection frame 24 under the action of gravity. The collection frame 24 collects the waste. If the waste inside the collection frame 24 needs to be processed, the user pulls the door 22 on the surface of the housing 1 to remove the door 22 from the surface of the housing 1. Then, the user pulls the collection frame 24 inside the cavity 23, causing the collection frame 24 to slide along the guide block 21 on the inner wall of the housing 1. Under the action of the guide block 21, the collection frame 24 is guided, and the collection frame 24 moves the elastic clip 25 away from the inner wall of the housing 1, thereby pulling the collection frame 24 out of the cavity 23 and processing the waste inside the collection frame 24 in a centralized manner, so as to realize the function of the flipper for centralized collection of waste.

[0027] Furthermore, such as Figure 2 and Figure 4 As shown, the surfaces of the flipping plate 108 and the fixture frame 116 are provided with a stabilizing clamping mechanism 3. The stabilizing clamping mechanism 3 consists of a cylinder 31, a first clamping plate 32, a sponge pad 33, a groove 34, and a second clamping plate 35. The surface of the flipping plate 108 is equipped with a cylinder 31, which can be an SMC series cylinder. The input end of the cylinder 31 is electrically connected to the output end of the controller 101. The surface of the fixture frame 116 is equipped with a second clamping plate 35, and the surface of the fixture frame 116 is provided with a first clamping plate 32. The surfaces of the first clamping plate 32 and the second clamping plate 35 are both equipped with sponge pads 33 for surface protection of the circuit board body 111. The surface of the fixture frame 116 is provided with a groove 34, which slides and engages with the surface of the first clamping plate 32.

[0028] During implementation, when the controller 101 controls the cylinder 31 to work, the cylinder 31 drives the first clamping plate 32 to move on the surface of the clamp frame 116, causing the first clamping plate 32 to slide inside the groove 34. Under the action of the groove 34, the first clamping plate 32 is guided, causing the first clamping plate 32 to move downward until it contacts the surface of the circuit board body 111. Under the combined action of the groove 34 and the first clamping plate 32, the surface of the circuit board body 111 is held by the groove 110, preventing the circuit board body 111 from shaking when flipping and hitting. Under the action of the sponge pad 33, the surface of the circuit board body 111 can be protected and prevented from damage, so as to realize the function of the flipping machine to firmly clamp the surface of the circuit board body 111.

[0029] Furthermore, such as Figure 3 and Figure 5 As shown, the surfaces of the chassis 1, the adjusting plate 102, and the fixed plate 103 are provided with a convenient adjustment mechanism 4. The convenient adjustment mechanism 4 consists of a fixed rod 41, a servo motor body 42, a shaft 43, a second lead screw body 44, and a second lead screw nut 45. The surface of the chassis 1 is provided with a second lead screw body 44. One end of the second lead screw body 44 passes through the adjusting plate 102 and rotates with the inner wall of the fixed plate 103. The surface of the second lead screw body 44 is threaded with a second lead screw nut 45, and the surface of the second lead screw nut 45 is fixed to the inner wall of the adjusting plate 102. The second lead screw nut 45 slides with the surface of the housing 1. The inner wall of the housing 1 is equipped with a servo motor body 42, which can be an HF series model. The input end of the servo motor body 42 is electrically connected to the output end of the controller 101. The output end of the servo motor body 42 is equipped with a shaft 43 through a coupling. One end of the shaft 43 is fixed to the surface of the second lead screw body 44. The inner walls of the housing 1 and the fixing plate 103 are both equipped with fixing rods 41, which slide with the surface at the bottom of the adjusting plate 102.

[0030] During implementation, the servo motor body 42 inside the control box 1 operates, driving the shaft 43 to rotate. When the shaft 43 rotates, it drives the second lead screw body 44 to rotate on the inner wall of the fixed plate 103. With the cooperation of the second lead screw body 44 and the second lead screw nut 45, the second lead screw nut 45 moves on the surface of the second lead screw body 44, thereby driving the adjusting plate 102 to move on the surface of the box 1. At this time, the adjusting plate 102 slides on the surface of the fixed rod 41. Under the action of the fixed rod 41, the adjusting plate 102 is guided to avoid the adjusting plate 102 from tilting when adjusting the position. This allows the size between the adjusting plate 102 and the fixed plate 103 to adapt to the processing needs of circuit board bodies 111 of different sizes, so as to realize the function of the flipping machine to flip circuit board bodies 111 of different sizes.

[0031] Working Principle: In use, first place the chassis 1 in the designated position. The user can adjust the distance between the adjusting plate 102 and the fixed plate 103 according to the different dimensions of the circuit board body 111. At this time, the user operates the controller 101, causing the controller 101 to control the servo motor body 42 inside the chassis 1 to work. Under the action of the servo motor body 42, the shaft 43 rotates. When the shaft 43 rotates, it drives the second lead screw body 44 to rotate on the inner wall of the fixed plate 103. The second lead screw body 44 and the second lead screw nut 45 work together to drive the second lead screw nut 45 to rotate on the second lead screw body 403. The surface movement of the 4 causes the adjustment plate 102 to move on the surface of the housing 1. At this time, the adjustment plate 102 slides on the surface of the fixing rod 41. Under the action of the fixing rod 41, the adjustment plate 102 is guided to avoid the phenomenon of the adjustment plate 102 being tilted when adjusting the position. This allows the size between the adjustment plate 102 and the fixing plate 103 to adapt to the processing needs of circuit board bodies 111 of different sizes, so as to realize the function of the flipping machine to flip circuit board bodies 111 of different sizes. This makes it convenient for users to adjust the position of the adjustment plate 102 when using the flipping machine, and makes the flipping machine more versatile in use.

[0032] Subsequently, the clamping frame 116, in its normal state, is located inside the groove 110, ready for operation. When the circuit board body 111 moves to one side of the fixing frame 104 via the conveying assembly 106, the position of the circuit board body 111 can be sensed by the photoelectric sensor 109, and a signal is transmitted to the controller 101. The controller 101 controls the clamping and flipping of the circuit board body 111 based on these signals. The photoelectric sensor 109 can accurately detect the position and state of the circuit board body 111, ensuring the smooth progress of the flipping process. After receiving the signal from the photoelectric sensor 109, the controller 101 clamps the circuit board body 111 from the surface of the conveying assembly 106. Subsequently, the controller 101 automatically controls the drive device (not shown in the diagram) on the surface of the first lead screw body 107 to rotate on the inner wall of the fixing frame 104 under the action of the drive device. The first lead screw body 107 rotates in cooperation with the first lead screw nut 113. The frame 114 and the flipping plate 108 move downwards. At this time, the frame 114 slides on the surface of the guide rod 112, and the guide rod 112 guides the frame 114. Under the combined action of the second clamping plate 35 and the first clamping plate 32, the circuit board body 111 is lifted and moved away from the surface of the conveying assembly 106. Subsequently, the controller 101 controls the rotation motor 115 inside the frame 114 to work. Under the action of the rotation motor 115, the flipping plate 108 is driven to move on the fixed frame 104. The internal rotation drives the fixture frame 116 to flip, which in turn flips the circuit board body 111. An external knocking device (not shown in the diagram) knocks off the waste material from the surface of the circuit board body 111, causing the waste material to automatically fall into the guide frame 105. At this time, the frame 114, the flipping plate 108, and the fixture frame 116 reset, causing the second clamping plate 35 and the first clamping plate 32 on the surface of the fixture frame 116 to move into the groove 110, ready for the next operation. The drive device, specifically a servo motor, is installed inside the chassis 1. Its purpose is to drive the first lead screw body 107 to achieve the lifting and lowering movement of the frame 114 and the flipping plate 108. The installation and connection method between the servo motor and the first lead screw body 107 is existing technology and will not be described further. The specific composition and working principle of the conveying component 106 are also existing technology and will not be described further.

[0033] Subsequently, when the controller 101 controls the cylinder 31 to work, the cylinder 31 drives the first clamping plate 32 to move on the surface of the clamp frame 116, causing the first clamping plate 32 to slide inside the groove 34. Under the action of the groove 34, the first clamping plate 32 is guided, causing the first clamping plate 32 to move downward until it contacts the surface of the circuit board body 111. Under the combined action of the groove 34 and the first clamping plate 32, the surface of the circuit board body 111 is held by the groove 110, preventing the circuit board body 111 from shaking when flipping and striking. Under the action of the sponge pad 33, the surface of the circuit board body 111 can be protected and prevented from damage, so as to realize the function of the flipping machine to firmly hold the surface of the circuit board body 111. Thus, when the flipping machine is used, it can firmly hold the circuit board body 111 for flipping, and at the same time, it can protect the surface of the circuit board body 111 from damage.

[0034] Subsequently, the waste falls into the guide frame 105 and automatically descends into the collection frame 24 under gravity. The collection frame 24 collects the waste. If the waste inside the collection frame 24 needs to be processed, the user pulls the door 22 on the surface of the housing 1 to remove it. Then, the user pulls the collection frame 24 inside the cavity 23, causing the collection frame 24 to slide against the guide block 21 on the inner wall of the housing 1. The guide block 21 guides the collection frame 24, causing the elastic latch 25 to move away from the inner wall of the housing 1, thus pulling the collection frame 24 out of the cavity 23. The waste inside the collection box 24 is centrally processed. Then, the user puts the cleaned collection box 24 into the cavity 23. The user pushes the collection box 24, causing the collection box 24 to automatically lock onto the inner wall of the chassis 1 with the elastic clip 25. Under the action of the elastic clip 25, the collection box 24 is prevented from shifting inside the cavity 23, so that the flipping machine can collect waste more effectively and realize the function of centrally collecting waste. This allows the flipping machine to collect the waste on the surface of the circuit board body 111 together for processing, making the flipping machine more convenient for the user to operate and finally completing the use of the flipping machine.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
