Description

Technical Field

[0001] The invention relates to the technical field of circuit board production equipment, and in particular to a circuit board reversing device. Background Art

[0002] PCB (Printed Circuit Board), Chinese name is printed circuit board, also known as printed circuit board, printed circuit board, is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made by electronic printing, it is called a "printed" circuit board. Circuit boards are essential components in the current electronics industry, and are used for electrical connections of electronic components. In the production and processing of circuit boards, multiple processes such as cutting, drilling, copper plating, image transfer, etching, testing, and silk screen printing are required. Therefore, the processing process involves the transmission of circuit boards. At present, when circuit boards are transmitted, conveyor lines are usually used to transmit circuit boards between equipment in different processes. In different processes and different processing equipment, there will be requirements for the direction of the circuit board. If the direction of the circuit board required by the equipment of the next process is different from the current one, the circuit board needs to be reversed when it is transmitted to the next process, so that the circuit board enters the equipment of the next process in another direction. In traditional practice, this reversing operation is done manually. As production and processing gradually turn to automation, rotary devices are used to replace manual work. At present, when reversing the circuit board, a rotary table is usually set up on the conveyor line. When the circuit board reaches the area where the rotary table is located, the rotary table lifts the circuit board and rotates it to a set angle. Then the rotary table descends and puts the circuit board back to the conveyor line. However, the above method is used for the rotational reversal of a single circuit board, while the actual production process usually involves circuit boards of different specifications. When processing some small-sized circuit boards, in order to improve efficiency, multiple circuit boards are usually conveyed side by side. When the conveyor belt conveys multiple circuit boards side by side at the same time, the above method cannot cope with the reversal of multiple circuit boards in a row. If the reversal operation is still performed one by one, it will seriously affect the transmission efficiency. Summary of the invention

[0025] Example 1

[0026] Reference Figures 1 to 8The present invention provides a circuit board reversing device, comprising: a frame 1, a circuit board reversing module 2, a rotary drive mechanism 3, a circuit board feeding module 4, and a circuit board discharging mechanism 5. The rotary drive mechanism 3 is arranged on the frame 1, and is used to drive the circuit board reversing module 2 to rotate. Specifically, the rotary drive mechanism 3 is connected to the rotating frame 21 of the circuit board reversing module 2, and drives the rotating frame 21 to rotate. The circuit board feeding module 4 is arranged on the frame 1, and the circuit board feeding module 4 is located on one side of the circuit board reversing module 2. The circuit board feeding module 4 is connected with other processes of circuit board production to transport the circuit board to the circuit board reversing module 2. The circuit board discharging mechanism 5 is arranged on the frame 1, and the circuit board discharging mechanism 5 is located on the other side of the circuit board reversing module 2. The circuit board discharging mechanism 5 is connected with other processes of circuit board production to transport the reversing circuit board to the next process.

[0027] The circuit board reversing module 2 is arranged on the frame 1, and the circuit board reversing module 2 includes a rotating frame 21, a circuit board conveying mechanism 22 connected to the rotating frame 21, and a reversing driving mechanism 23 arranged on the rotating frame 21 for driving the circuit board conveying mechanism 22 to rotate. The reversing driving mechanism 23 can drive the circuit board conveying mechanism 22 to rotate, so as to change the direction of the circuit board during the process of conveying the circuit board. The circuit board conveying mechanism 22 first grabs the circuit board in the circuit board feeding module 4, and then the rotating frame 21 rotates under the drive of the reversing driving mechanism 23 to move the circuit board out of the circuit board feeding module 4.

[0028] The circuit board conveying mechanism 22 includes a reversing bracket 221 connected to the rotating frame 21, a plurality of upper clamping assemblies 222 connected to the reversing bracket 221, a lifting bracket 223 movably connected to the reversing bracket 221, a plurality of lower clamping assemblies 224 arranged on the lifting bracket 223 and matching with the upper clamping assemblies 222, a clamping driving member 225 arranged on the reversing bracket 221 and used to drive the lifting bracket 223 to move, and the reversing driving mechanism 23 is in transmission connection with the reversing bracket 221. In this embodiment, there is the same interval between adjacent upper clamping assemblies 222, and the lower clamping assemblies 224 correspond to the upper clamping assemblies 222 one by one, and the upper clamping assemblies 222 / lower clamping assemblies 224 basically cover the conveying area of ​​the circuit board feeding module 4, so that it can not only grab a single large-sized circuit board, but also grab a plurality of small-sized circuit boards conveyed side by side, and flexibly cope with the reversing operation of circuit boards of different specifications.

The first reversing drive 232 drives the reversing movable frame 231 to approach or move away from the center of the rotating frame 21, and the second reversing drive 233 can drive the reversing bracket 221 to rotate ninety degrees. When the circuit board conveying mechanism 22 is located at a position corresponding to the circuit board feeding module 4, the first reversing drive 232 drives the reversing movable frame 231 away from the center of the rotating frame 21, that is, drives the circuit board conveying mechanism 22 to move toward the circuit board feeding module 4, so as to facilitate the grabbing of the circuit board. In this embodiment, the first reversing drive 232 and the second reversing drive 233 are both cylinders.

[0030] The upper clamping assembly 222 includes a clamping fixture 222a connected to the reversing bracket 221, a plurality of buffer rods 222b connected to the clamping fixture 222a, and an upper clamping member 222c connected to the bottom of the buffer rod 222b. In this embodiment, the buffer rod 222b is specifically a spring arranged outside the connecting rod. When the clamping driving member 225 drives the lifting frame to move upward, the lower clamping assembly 224 contacts the bottom of the circuit board, and the upper clamping assembly 222 contacts the top surface of the circuit board. The buffer rod 222b can play a buffering role to prevent the impact force from damaging the circuit board.

[0031] The rotary drive mechanism 3 includes a first drive motor 31 arranged on the frame 1, and a divider 32 arranged on the frame 1. The output end of the first drive motor 31 is connected to the input end of the divider 32 through a pulley group, and the input end of the divider 32 is connected to the rotating frame 21. In this embodiment, under the action of the divider 32, the rotating frame 21 rotates ninety degrees each time, that is, the circuit board changing module in this embodiment has four stations, wherein the first station corresponds to the circuit board feeding module 4, which is used to clamp the circuit board, the second station is a transition station, and the circuit board conveying mechanism 22 is reversed during the transfer of the circuit board from the first station to the second station (that is, the circuit board is reversed), the third station corresponds to the circuit board discharge mechanism 5, which is used to place the reversed circuit board on the circuit board discharge mechanism 5, and the fourth station is also a transition station, and the circuit board conveying mechanism 22 is reset during the movement from the third station to the fourth station. Corresponding to the four stations, four circuit board conveying mechanisms 22 are provided in this embodiment.

[0032] The circuit board feeding module 4 includes a feeding conveying mechanism 41 and a loading conveying mechanism 42, and the loading conveying mechanism 42 is located between the feeding conveying mechanism 41 and the circuit board loading module. The feeding conveying mechanism 41 is connected with other processes of circuit board production to convey the circuit board to the loading conveying mechanism 42, and the loading conveying mechanism 42 conveys the circuit board to a position corresponding to the circuit board reversing module 2. The loading conveying mechanism 42 includes a loading conveying frame 421, and a plurality of loading conveying belts 422 arranged on the loading conveying frame 421. There is a gap corresponding to the upper clamping assembly 222 or the lower clamping assembly 224 between adjacent loading conveying belts 422, so that the lower clamping assembly 224 can enter the gap and cooperate with the upper clamping assembly 222 to clamp the circuit board.

[0033] The circuit board discharge mechanism 5 includes a discharge bracket 51 connected to the frame 1, and a plurality of discharge roller groups 52 arranged on the discharge bracket 51. There is a gap corresponding to the upper clamping assembly 222 or the lower clamping assembly 224 between adjacent discharge roller groups 52, and the lower clamping assembly 224 can enter the gap to facilitate placing the circuit board on the discharge roller group 52. The discharge roller group 52 specifically includes a rotating shaft and a plurality of rollers arranged on the rotating shaft, and the discharge roller group 52 is driven by a motor.

[0034] Attach Figure 1 The perspective describes the working process of the present invention. The circuit board feeding module 4 conveys the circuit boards from left to right. In this embodiment, three circuit boards are conveyed in a row. The circuit board is transported to the loading conveying mechanism 42 via the feeding conveying mechanism 41 and arrives at the end of the loading conveying mechanism 42 (i.e., the first station). The circuit board conveying mechanism 22 is driven by the first reversing drive member 232 to approach the loading conveying mechanism 42 and clamp the circuit board. After clamping the circuit board, the first reversing drive member 232 is reset, and the rotary drive mechanism 3 drives the rotating frame 21 to rotate ninety degrees (turn to the second station). During the rotation, the second reversing drive member 233 simultaneously drives the circuit board conveying mechanism 22 to rotate ninety degrees. Then the rotary drive mechanism 3 continues to drive the rotating frame 21 to rotate ninety degrees. The circuit board conveying mechanism 22 arrives at the position corresponding to the circuit board discharge mechanism 5 (i.e., the third station) and places the circuit board on the circuit board discharge mechanism 5. At this time, the circuit board is reversed by ninety degrees. Then the rotating frame 21 continues to rotate ninety degrees. During the rotation of the rotating frame 21, the second reversing drive member 233 is reset, and the circuit board conveying mechanism 22 returns to the initial state and enters the fourth station to wait for the next circuit board to be grabbed. The working process of the present invention is a continuous operation, that is, when the first circuit board conveying mechanism 22 grabs the circuit board and transfers it to the second station, the second circuit board conveying mechanism 22 arriving at the first station continues to perform the same action of grabbing the circuit board, and so on.

[0035] Although the present embodiment can realize the simultaneous reversal of multiple circuit boards arranged side by side, it cannot be guaranteed that the circuit boards are always in the same direction without being skewed during the transportation process. If the circuit boards are skewed, the circuit boards after the subsequent reversal will also be skewed, and the skewed circuit boards may also affect the grasping of the circuit board conveying mechanism 22, and may also cause the boards to be stuck during the subsequent transmission process. Therefore, the present invention proposes embodiment 2.

[0036] Example 2

[0037] Reference Figures 1 to 8 A circuit board reversing device comprises: a frame 1, a circuit board reversing module 2, a rotary drive mechanism 3, a circuit board feeding module 4, and a circuit board discharging mechanism 5. The rotary drive mechanism 3 is arranged on the frame 1, and is used to drive the circuit board reversing module 2 to rotate. Specifically, the rotary drive mechanism 3 is connected to the rotating frame 21 of the circuit board reversing module 2, and drives the rotating frame 21 to rotate. The circuit board feeding module 4 is arranged on the frame 1, and the circuit board feeding module 4 is located on one side of the circuit board reversing module 2.

The circuit board discharging mechanism 5 is connected with other processes of circuit board production to transport the reversed circuit board to the next process.

[0038] The circuit board reversing module 2 is arranged on the frame 1, and the circuit board reversing module 2 includes a rotating frame 21, a circuit board conveying mechanism 22 connected to the rotating frame 21, and a reversing driving mechanism 23 arranged on the rotating frame 21 for driving the circuit board conveying mechanism 22 to rotate. The reversing driving mechanism 23 can drive the circuit board conveying mechanism 22 to rotate, so as to change the direction of the circuit board during the process of conveying the circuit board. The circuit board conveying mechanism 22 first grabs the circuit board in the circuit board feeding module 4, and then the rotating frame 21 rotates under the drive of the reversing driving mechanism 23 to move the circuit board out of the circuit board feeding module 4.

In this embodiment, there is the same interval between adjacent upper clamping assemblies 222, and the lower clamping assemblies 224 correspond to the upper clamping assemblies 222 one by one, and the upper clamping assemblies 222 / lower clamping assemblies 224 basically cover the conveying area of ​​the circuit board feeding module 4, so that it can not only grab a single large-sized circuit board, but also grab a plurality of small-sized circuit boards conveyed side by side, and flexibly cope with the reversing operation of circuit boards of different specifications.

[0040] The reversing drive mechanism 23 includes a reversing movable frame 231 movably connected to the rotating frame 21, a first reversing drive member 232 arranged on the rotating frame 21 for driving the first reversing movable frame 231 to move, a second reversing drive member 233 arranged on the movable frame, and a rocker 234 with one end connected to the output end of the second reversing drive member 233, the other end of the rocker 234 is connected to the reversing bracket 221, specifically, a transfer shaft is provided on the reversing movable frame 231, the rocker 234 is connected to the transfer shaft, the transfer shaft is connected to the reversing bracket 221, and the end of the second reversing drive member 233 is rotatably connected to the reversing movable frame 231. The first reversing drive 232 drives the reversing movable frame 231 to approach or move away from the center of the rotating frame 21, and the second reversing drive 233 can drive the reversing bracket 221 to rotate ninety degrees. When the circuit board conveying mechanism 22 is located at a position corresponding to the circuit board feeding module 4, the first reversing drive 232 drives the reversing movable frame 231 away from the center of the rotating frame 21, that is, drives the circuit board conveying mechanism 22 to move toward the circuit board feeding module 4, so as to facilitate the grabbing of the circuit board. In this embodiment, the first reversing drive 232 and the second reversing drive 233 are both cylinders.

[0041] The upper clamping assembly 222 includes a clamping fixture 222a connected to the reversing bracket 221, a plurality of buffer rods 222b connected to the clamping fixture 222a, and an upper clamping member 222c connected to the bottom of the buffer rod 222b. In this embodiment, the buffer rod 222b is specifically a spring arranged outside the connecting rod. When the clamping driving member 225 drives the lifting frame to move upward, the lower clamping assembly 224 contacts the bottom of the circuit board, and the upper clamping assembly 222 contacts the top surface of the circuit board. The buffer rod 222b can play a buffering role to prevent the impact force from damaging the circuit board.

[0042] The rotary drive mechanism 3 includes a first drive motor 31 arranged on the frame 1, and a divider 32 arranged on the frame 1. The output end of the first drive motor 31 is connected to the input end of the divider 32 through a pulley group, and the input end of the divider 32 is connected to the rotating frame 21. In this embodiment, under the action of the divider 32, the rotating frame 21 rotates ninety degrees each time, that is, the circuit board changing module in this embodiment has four stations, wherein the first station corresponds to the circuit board feeding module 4, which is used to clamp the circuit board, the second station is a transition station, and the circuit board conveying mechanism 22 is reversed during the transfer of the circuit board from the first station to the second station (that is, the circuit board is reversed), the third station corresponds to the circuit board discharge mechanism 5, which is used to place the reversed circuit board on the circuit board discharge mechanism 5, and the fourth station is also a transition station, and the circuit board conveying mechanism 22 is reset during the movement from the third station to the fourth station. Corresponding to the four stations, four circuit board conveying mechanisms 22 are provided in this embodiment.

[0043] The circuit board feeding module 4 includes a feeding conveying mechanism 41 and a loading conveying mechanism 42, and the loading conveying mechanism 42 is located between the feeding conveying mechanism 41 and the circuit board loading module. The feeding conveying mechanism 41 is connected with other processes of circuit board production to convey the circuit board to the loading conveying mechanism 42, and the loading conveying mechanism 42 conveys the circuit board to a position corresponding to the circuit board reversing module 2. The loading conveying mechanism 42 includes a loading conveying frame 421, and a plurality of loading conveying belts 422 arranged on the loading conveying frame 421. There is a gap corresponding to the upper clamping assembly 222 or the lower clamping assembly 224 between adjacent loading conveying belts 422, so that the lower clamping assembly 224 can enter the gap and cooperate with the upper clamping assembly 222 to clamp the circuit board.

[0044] The circuit board feeding module 4 includes a sieve plate mechanism 43, which includes an induction component 431 arranged on the feeding conveying mechanism 41, a sieve plate component 432 connected to the feeding conveying mechanism 41, and a placement table 433 arranged above the loading conveying mechanism 42, wherein the sieve plate component 432 is rotatably connected to the feeding conveying component, and a sieve plate cylinder 434 for driving the sieve plate component 432 to rotate is also arranged below the sieve plate component 432. In this embodiment, a baffle 433a is arranged on one side of the placement table 433 close to the circuit board reversing module 2 to prevent the circuit board from falling from the placement table 433. When the circuit board is conveyed, it cannot be guaranteed to always maintain the set direction 100%. When the circuit board is skewed, the subsequent reversal is also in the wrong direction. Therefore, the sieve plate mechanism 43 is used to screen out circuit boards with skewed directions. In this embodiment, the sensing component 431 specifically includes a bracket and a sensor arranged on the bracket. The sensor can be an optical fiber sensor. The optical fiber sensor senses the time the circuit board passes through to determine whether the circuit board is skewed. For example, when the direction of a circuit board of a certain specification is correct, the time it takes to pass the sensor is 2s (this time is only an example, and the error range can be set in actual implementation). When the time the circuit board passes through the sensor is inconsistent with this time, it is determined that the direction of the circuit board is skewed. In addition, the specific implementation sensor can also use other types of sensors, such as image sensors. The sieve plate cylinder 434 drives the end of the sieve plate assembly 432 to rotate between the feeding conveying mechanism 42 and the placement table 433. When the piston rod of the sieve plate cylinder 434 is extended, the end of the sieve plate assembly 432 rotates upward to the same height as the placement table 433. At this time, the circuit board is transported to the placement table 433. That is, when the sensor detects that the direction of the circuit board is skewed, the piston rod of the sieve plate cylinder 434 is extended, so that the circuit board is transported to the placement table 433. After that, the skewed circuit board can be taken away by the staff or a robot provided separately.

[0045] The sieve plate assembly 432 includes a sieve plate frame 432a rotatably connected to the feed conveying mechanism 41, a plurality of conveying roller groups 432b arranged on the sieve plate frame 432a, a pressing plate bracket 432c arranged on the sieve plate frame 432a, and a plurality of pressing plate assemblies 435 evenly arranged on the pressing plate bracket 432c. When the end of the sieve plate assembly 432 moves upward, it tilts relative to the horizontal plane, and the circuit board may slide down at this time, and the pressing plate assembly 435 can test the force perpendicular to the plane of the sieve plate assembly 432 to the circuit board, ensuring that the circuit board and the conveying roller group 432b have sufficient friction to avoid sliding down, so that the conveying roller group 432b can smoothly deliver the circuit board to the placement table 433.

[0046] The pressure plate assembly 435 includes a first pressure plate fixing member 435a connected to the pressure plate bracket 432c, a connecting rod 435b connected to the pressure plate fixing member, a second pressure plate fixing member 435c disposed at the bottom of the connecting rod 435b, and a plurality of pressure plate wheels 435d connected to the second pressure plate fixing member 435c. A spring is sleeved on the connecting rod 435b, and the spring provides downward pressure to the pressure plate, so that the pressure plate wheels 435d contact the circuit board.

[0047] The circuit board discharge mechanism 5 includes a discharge bracket 51 connected to the frame 1, and a plurality of discharge roller groups 52 arranged on the discharge bracket 51. There is a gap corresponding to the upper clamping assembly 222 or the lower clamping assembly 224 between adjacent discharge roller groups 52, and the lower clamping assembly 224 can enter the gap to facilitate placing the circuit board on the discharge roller group 52. The discharge roller group 52 specifically includes a rotating shaft and a plurality of rollers arranged on the rotating shaft, and the discharge roller group 52 is driven by a motor.

[0048] Attach Figure 1 The perspective described above describes the working process of the present invention. The circuit board feeding module 4 conveys the circuit board from left to right. In this embodiment, three circuit boards are conveyed in a row. When the circuit board passes through the sensing component 431, if it is detected that the circuit board is skewed, the screen plate mechanism 43 guides the circuit board to the placement table 433. If the direction of the circuit board is normal, the circuit board is continued to be conveyed to the loading conveying mechanism 42. When it reaches the end of the loading conveying mechanism 42 (i.e., the first station), the circuit board conveying mechanism 22 approaches the loading conveying mechanism 42 and clamps the circuit board under the drive of the first reversing drive member 232. After clamping the circuit board, the first reversing drive member 232 is reset, and the rotating drive mechanism 3 drives The rotating frame 21 rotates ninety degrees (turns to the second station), and during the rotation process, the second reversing drive 233 drives the circuit board conveying mechanism 22 to rotate ninety degrees at the same time, and then the rotating drive mechanism 3 continues to drive the rotating frame 21 to rotate ninety degrees, and the circuit board conveying mechanism 22 reaches the position corresponding to the circuit board discharge mechanism 5 (i.e., the third station), and places the circuit board on the circuit board discharge mechanism 5. At this time, the circuit board realizes a ninety-degree reversal, and then the rotating frame 21 continues to rotate ninety degrees. During the rotation of the rotating frame 21, the second reversing drive 233 is reset, and the circuit board conveying mechanism 22 returns to the initial state and enters the fourth station to wait for the next circuit board to be grabbed. The working process of the present invention is a continuous operation, that is, when the first circuit board conveying mechanism 22 grabs the circuit board and transfers it to the second station, the second circuit board conveying mechanism 22 that arrives at the first station continues to perform the same action of grabbing the circuit board, and so on.
