Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of circuit board production equipment, and particularly relates to a circuit board reversing device. BACKGROUND

[0002] PCB (Printed Circuit Board), Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, is the support of electronic components, and is the provider of electrical connection of electronic components. Since it is made by electronic printing, it is called "printed" circuit board. The circuit board is an essential element in the current electronic industry, which is used for electrical connection of electronic components. In the production and processing process of the circuit board, it needs to involve cutting, drilling, copper sinking, image transfer, etching, detection, silk screen printing and other processes, so the processing process will involve the transmission of the circuit board. At present, the circuit board is usually transmitted by a conveying line between different process equipment, and in different processes and different processing equipment, the orientation of the circuit board is required. If the direction of the circuit board required by the next process equipment 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 next process equipment in another direction. In the traditional way, this reversing operation is manually performed. With the gradual automation of production and processing, a rotating device is used to replace manual operation. At present, when the circuit board is reversed, a rotating table is usually arranged on the conveying line. When the circuit board reaches the area where the rotating table is located, the rotating table lifts the circuit board and rotates by a set angle, and then the rotating table lowers the circuit board back to the conveying line. However, the above-mentioned method is used for single circuit board rotation and reversing, and in actual production process, different specifications of circuit boards are usually involved. In order to improve the efficiency, multiple circuit boards are usually conveyed side by side when processing some small size circuit boards. When the conveying belt simultaneously conveys multiple circuit boards side by side, the above-mentioned method cannot cope with the reversing of multiple circuit boards in a row. If the reversing operation is still performed one by one, the transmission efficiency will be seriously affected. SUMMARY

The circuit board conveying mechanism 22 first grasps the circuit board in the circuit board feeding module 4, and then the rotating frame 21 rotates under the driving of the reversing driving mechanism 23 and moves the circuit board out of the circuit board feeding module 4.

[0035] The circuit board conveying mechanism 22 comprises a reversing support 221 connected with the rotating frame 21, a plurality of upper clamping assemblies 222 connected with the reversing support 221, a lifting support 223 movably connected with the reversing support 221, a plurality of lower clamping assemblies 224 arranged on the lifting support 223 and matched with the upper clamping assemblies 222, a clamping driving member 225 arranged on the reversing support 221 and used for driving the lifting support 223 to move, and the reversing driving mechanism 23 is in transmission connection with the reversing support 221. In the embodiment, the adjacent upper clamping assemblies 222 have the same interval, the lower clamping assemblies 224 and the upper clamping assemblies 222 are one-to-one corresponding, and the upper clamping assemblies 222 / lower clamping assemblies 224 basically cover the conveying area of the circuit board feeding module 4, so that a single circuit board with large size can be grasped, a plurality of small-size circuit boards conveyed side by side can be grasped, and the reversing operation of circuit boards with different specifications can be flexibly coped with.

[0036] The reversing driving mechanism 23 comprises a reversing moving frame 231 movably connected to the rotating frame 21, a first reversing driving member 232 arranged on the rotating frame 21 and used to drive the reversing moving frame 231 to move, a second reversing driving member 233 arranged on the reversing moving frame 231, and a rocker 234 having one end connected to the output end of the second reversing driving member 233 and the other end connected to the reversing support 221.

The circuit board conveying mechanism 22 reverses (i.e., the circuit board reverses) during the process of transferring the circuit board from the first station to the second station. The third station corresponds to the circuit board discharging mechanism 5 and is used to place the reversed circuit board on the circuit board discharging mechanism 5. The fourth station is also a transition station. The circuit board conveying mechanism 22 resets during the process of moving from the third station to the fourth station. Corresponding to the four stations, four circuit board conveying mechanisms 22 are arranged in the embodiment.

[0039] The circuit board feeding module 4 comprises a feeding conveying mechanism 41 and a feeding conveying mechanism 42 located between the feeding conveying mechanism 41 and the circuit board reversing module. The feeding conveying mechanism 41 is connected with other processes of the circuit board production, and the circuit board is conveyed to the feeding conveying mechanism 42, and the feeding conveying mechanism 42 conveys the circuit board to the position corresponding to the circuit board reversing module 2. The feeding conveying mechanism 42 comprises a feeding conveying frame 421, a plurality of feeding conveying belts 422 arranged on the feeding conveying frame 421, and a space corresponding to the upper clamping assembly 222 or the lower clamping assembly 224 between adjacent feeding conveying belts 422, so that the lower clamping assembly 224 can enter the space and cooperate with the upper clamping assembly 222 to clamp the circuit board.

[0040] The circuit board feeding module 4 comprises a feeding conveying mechanism 41 and a feeding conveying mechanism 42 located between the feeding conveying mechanism 41 and the circuit board reversing module. The feeding conveying mechanism 41 is connected with other processes of the circuit board production, and the circuit board is conveyed to the feeding conveying mechanism 42, and the feeding conveying mechanism 42 conveys the circuit board to the position corresponding to the circuit board reversing module 2. The feeding conveying mechanism 42 comprises a feeding conveying frame 421, a plurality of feeding conveying belts 422 arranged on the feeding conveying frame 421, and a space corresponding to the upper clamping assembly 222 or the lower clamping assembly 224 between adjacent feeding conveying belts 422, so that the lower clamping assembly 224 can enter the space and cooperate with the upper clamping assembly 222 to clamp the circuit board.

[0041] The circuit board feeding module 4 comprises a feeding conveying mechanism 41 and a feeding conveying mechanism 42 located between the feeding conveying mechanism 41 and the circuit board reversing module. The feeding conveying mechanism 41 is connected with other processes of the circuit board production, and the circuit board is conveyed to the feeding conveying mechanism 42, and the feeding conveying mechanism 42 conveys the circuit board to the position corresponding to the circuit board reversing module 2. The feeding conveying mechanism 42 comprises a feeding conveying frame 421, a plurality of feeding conveying belts 422 arranged on the feeding conveying frame 421, and a space corresponding to the upper clamping assembly 222 or the lower clamping assembly 224 between adjacent feeding conveying belts 422, so that the lower clamping assembly 224 can enter the space and cooperate with the upper clamping assembly 222 to clamp the circuit board. Figure 1 The working process of the present application is described from the perspective of the circuit board feeding module 4 conveying the circuit board from left to right, and in this embodiment, three circuit boards are conveyed in a row. The circuit board is conveyed to the feeding conveying mechanism 42 through the feeding conveying mechanism 41, reaches the end of the feeding conveying mechanism 42 (i.e. the first station), and the circuit board conveying mechanism 22 is driven by the first reversing drive 232 to approach the feeding conveying mechanism 42 and clamp the circuit board. After clamping the circuit board, the first reversing drive 232 is reset, the rotating drive mechanism 3 drives the rotating frame 21 to rotate by ninety degrees (to the second station), and in the process of rotating, the second reversing drive 233 simultaneously drives the circuit board conveying mechanism 22 to rotate by ninety degrees. Then the rotating drive mechanism 3 continues to drive the rotating frame 21 to rotate by ninety degrees, and the circuit board conveying mechanism 22 reaches the position corresponding to the circuit board discharging mechanism 5 (i.e. the third station) and places the circuit board on the circuit board discharging mechanism 5. At this time, the circuit board is reversed by ninety degrees, and then the rotating frame 21 continues to rotate by ninety degrees. In the process of rotating 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 time to grab the circuit board. The working process of the present application is continuous operation, that is, when the first circuit board conveying mechanism 22 grabs the circuit board and moves to the second station, the second circuit board conveying mechanism 22 that reaches the first station continues to perform the same action of grabbing the circuit board, and so on.

[0042] Although the embodiment can realize simultaneous commutation of multiple circuit boards side by side, the circuit boards cannot be guaranteed to be in the same direction without skewing during the conveying process. If the circuit boards skew, the subsequent commuted circuit boards are also skewed, and the skewed circuit boards can affect the grabbing of the circuit board conveying mechanism 22 and cause the subsequent transmission process to be blocked. The present application proposes embodiment 2.

The rotary drive mechanism 3 is arranged on the rack 1 and is used to drive the circuit board commutation module 2 to rotate. Specifically, the rotary drive mechanism 3 is connected with a rotating frame 21 of the circuit board commutation module 2 and drives the rotating frame 21 to rotate. The circuit board feeding module 4 is arranged on the rack 1 and is located on one side of the circuit board commutation module 2. The circuit board feeding module 4 is connected with other processes of circuit board production and conveys the circuit boards to the circuit board commutation module 2. The circuit board discharging mechanism 5 is arranged on the rack 1 and is located on the other side of the circuit board commutation module 2. The circuit board discharging mechanism 5 is connected with other processes of circuit board production and conveys the commuted circuit boards to the next process.

[0045] The circuit board commutation module 2 is arranged on the rack 1 and comprises a rotating frame 21, a circuit board conveying mechanism 22 connected with the rotating frame 21, and a commutation drive mechanism 23 arranged on the rotating frame 21 and used to drive the circuit board conveying mechanism 22 to rotate. The commutation drive mechanism 23 can drive the circuit board conveying mechanism 22 to rotate so as to change the direction of the circuit board during the conveying process. The circuit board conveying mechanism 22 first grabs the circuit board at the circuit board feeding module 4, and then the rotating frame 21 rotates under the drive of the commutation drive mechanism 23 to move the circuit board out of the circuit board feeding module 4.

[0046] The circuit board conveying mechanism 22 comprises a reversing support 221 connected with the rotating frame 21, a plurality of upper clamping assemblies 222 connected with the reversing support 221, a lifting support 223 movably connected with the reversing support 221, a plurality of lower clamping assemblies 224 arranged on the lifting support 223 and matched with the upper clamping assemblies 222, a clamping driving member 225 arranged on the reversing support 221 and used for driving the lifting support 223 to move, and the reversing driving mechanism 23 is drivingly connected with the reversing support 221. In the embodiment, the adjacent upper clamping assemblies 222 have the same interval, and the upper clamping assemblies 222 and the lower clamping assemblies 224 correspond to each other. The upper clamping assemblies 222 / lower clamping assemblies 224 substantially cover the conveying area of the circuit board feeding module 4, so that a single circuit board of large size can be gripped, and a plurality of circuit boards of small size conveyed side by side can also be gripped, thereby flexibly coping with the reversing operation of circuit boards of different specifications.

[0047] The reversing driving mechanism 23 comprises a reversing moving frame 231 movably connected with the rotating frame 21, a first reversing driving member 232 arranged on the rotating frame 21 and used for driving the reversing moving frame 231 to move, a second reversing driving member 233 arranged on the moving frame, and a rocker 234 having one end connected with the output end of the second reversing driving member 233.

The first reversing driving member 232 drives the reversing moving frame 231 to move close to or away from the center of the rotating frame 21, and the second reversing driving member 233 can drive the reversing support 221 to rotate by ninety degrees. When the circuit board conveying mechanism 22 is located at the position corresponding to the circuit board feeding module 4, the first reversing driving member 232 drives the reversing moving frame 231 to move away from the center of the rotating frame 21, that is, drives the circuit board conveying mechanism 22 to move towards the circuit board feeding module 4, thereby facilitating the gripping of the circuit board. In the embodiment, the first reversing driving member 232 and the second reversing driving member 233 are both air cylinders.

[0048] The upper clamping assembly 222 comprises a clamping fixing member 222a connected with the reversing support 221, a plurality of buffer rods 222b connected with the clamping fixing member 222a, and an upper clamping member 222c connected with the bottom of the buffer rod 222b. In the embodiment, the buffer rod 222b is specifically a connecting rod sleeved with a spring. When the lifting frame is driven by the clamping driving member 225 to move upwards, 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, thereby avoiding the damage of impact force to the circuit board.

[0049] The rotating driving mechanism 3 comprises a first driving motor 31 arranged on the frame 1, and a divider 32 arranged on the frame 1, the output end of the first driving motor 31 is drivingly connected with the input end of the divider 32 through a belt wheel set, and the input end of the divider 32 is drivingly connected with the rotating frame 21. In this embodiment, under the action of the divider 32, the rotating frame 21 rotates by 90 degrees each time, that is, the circuit board reversing module in this embodiment has four work stations, wherein the first work station corresponds to the circuit board feeding module 4 and is used for clamping the circuit board, the second work station is a transition work station, the circuit board conveying mechanism 22 reverses the circuit board during the process of transferring the circuit board from the first work station to the second work station (that is, the circuit board is reversed), the third work station corresponds to the circuit board discharging mechanism 5 and is used for placing the reversed circuit board on the circuit board discharging mechanism 5, and the fourth work station is also a transition work station, and the circuit board conveying mechanism 22 is reset during the process of moving from the third work station to the fourth work station. Corresponding to the four work stations, four circuit board conveying mechanisms 22 are arranged in this embodiment.

[0050] The circuit board feeding module 4 comprises a feeding conveying mechanism 41 and a feeding conveying mechanism 42, and the feeding conveying mechanism 42 is located between the feeding conveying mechanism 41 and the circuit board reversing module. The feeding conveying mechanism 41 is connected with other processes of the circuit board production, and the circuit board is conveyed to the feeding conveying mechanism 42, and the feeding conveying mechanism 42 conveys the circuit board to the position corresponding to the circuit board reversing module 2. The feeding conveying mechanism 42 comprises a feeding conveying frame 421, a plurality of feeding conveying belts 422 arranged on the feeding conveying frame 421, and the adjacent feeding conveying belts 422 have a spacing corresponding to the upper clamping assembly 222 or the lower clamping assembly 224, so that the lower clamping assembly 224 can enter the spacing and cooperate with the upper clamping assembly 222 to clamp the circuit board.

[0051] The circuit board feeding module 4 further comprises a sieve plate mechanism 43, which comprises a sensing assembly 431 arranged on the feeding conveying mechanism 41, a sieve plate assembly 432 connected with the feeding conveying mechanism 41, and a placement table 433 arranged above the feeding conveying mechanism 42. The sieve plate assembly 432 is rotationally connected with the feeding conveying mechanism 41, and a sieve plate cylinder 434 for driving the sieve plate assembly 432 to rotate is further arranged below the sieve plate assembly 432. In the embodiment, the placement table 433 is provided with a baffle 433a on the side close to the circuit board reversing module 2 to prevent the circuit board from falling off the placement table 433. When the circuit board is conveyed, it cannot be guaranteed that the circuit board always maintains the set direction. When the circuit board is skewed, the subsequent reversing is also in the wrong direction. Therefore, the sieve plate mechanism 43 is used to screen out the circuit board with skewed direction. In the embodiment, the sensing assembly 431 specifically comprises a bracket and a sensor arranged on the bracket. The sensor can be an optical fiber sensor. The time for the circuit board to pass through the sensor is sensed by the optical fiber sensor to determine whether the circuit board is skewed. For example, when the direction of a certain specification of circuit board is correct, the time for the circuit board to pass through the sensor is 2s (the time is only an example, and an error range can be set in actual implementation). When the time for the circuit board to pass through the sensor is inconsistent with the time, it is determined that the direction of the circuit board is skewed. In addition, the sensor can also be of other types, such as an image sensor. 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 is rotated upward to the same height as the placement table 433. At this time, the circuit board is conveyed to the placement table 433. 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 conveyed to the placement table 433. Then, the skewed circuit board can be taken away by the worker or the additional mechanical hand.

[0052] The sieve plate assembly 432 comprises a sieve plate frame 432a rotationally connected with the feeding conveying mechanism 41, a plurality of conveying roller groups 432b arranged on the sieve plate frame 432a, a pressing plate support 432c arranged on the sieve plate frame 432a, and a plurality of pressing plate assemblies 435 uniformly arranged on the pressing plate support 432c. When the end of the sieve plate assembly 432 moves upward, it is inclined relative to the horizontal plane. At this time, the circuit board can slide downward. The pressing plate assemblies 435 can apply a force perpendicular to the plane of the sieve plate assembly 432 to the circuit board to ensure that the circuit board and the conveying roller groups 432b have sufficient friction to prevent the circuit board from sliding downward, so that the conveying roller groups 432b can smoothly convey the circuit board to the placement table 433.

[0053] The pressing plate assembly 435 comprises a first pressing plate fixing member 435a connected with the pressing plate support 432c, a connecting rod 435b connected with the first pressing plate fixing member 435a, a second pressing plate fixing member 435c arranged at the bottom of the connecting rod 435b, and a plurality of pressing plate wheels 435d connected with the second pressing plate fixing member 435c. A spring is sleeved on the connecting rod 435b, which provides a pressing force to the pressing plate, so that the pressing plate wheels 435d are in contact with the circuit board.

[0054] The circuit board discharging mechanism 5 comprises a discharging support 51 connected with the rack 1, a plurality of discharging roller sets 52 arranged on the discharging support 51, and intervals corresponding to the upper clamping assembly 222 or the lower clamping assembly 224 between adjacent discharging roller sets 52, so that the lower clamping assembly 224 can enter the interval to facilitate placing the circuit board on the discharging roller set 52. The discharging roller set 52 specifically comprises a rotating shaft and a plurality of rollers arranged on the rotating shaft, and is driven by a motor.

[0055] The accompanying drawings Figure 1 The working process of the present application is described as follows. The circuit board feeding module 4 conveys the circuit board from left to right, and in this embodiment, one row conveys three circuit boards. When the circuit board passes through the sensing assembly 431, if the circuit board is detected to be skewed, the sieve 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 continuously conveyed to the feeding conveying mechanism 42, reaches the end of the feeding conveying mechanism 42 (i.e., the first station), and the circuit board conveying mechanism 22 is driven by the first reversing drive member 232 to approach the feeding conveying mechanism 42 and clamp the circuit board. After clamping the circuit board, the first reversing drive member 232 is reset. The rotating drive mechanism 3 drives the rotating frame 21 to rotate by ninety degrees (to the second station). In the process of rotating, the second reversing drive member 233 simultaneously drives the circuit board conveying mechanism 22 to rotate by ninety degrees. Then the rotating drive mechanism 3 continues to drive the rotating frame 21 to rotate by ninety degrees, and the circuit board conveying mechanism 22 reaches the corresponding position of the circuit board discharging mechanism 5 (i.e., the third station) to place the circuit board on the circuit board discharging mechanism 5. At this time, the circuit board is reversed by ninety degrees. Then the rotating frame 21 continues to rotate by ninety degrees. In the process of rotating 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 time to grab the circuit board. The working process of the present application is continuous operation, that is, when the first circuit board conveying mechanism 22 grabs the circuit board and moves to the second station, the second circuit board conveying mechanism 22 that reaches the first station continues to perform the same action of grabbing the circuit board, and so on.
