Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, and in particular to a novel automatic printing circuit board separation device. Background Technology

[0002] In the PCB depaneling process, PCB depaneling machines are typically used to divide printed circuit boards. PCB depaneling machines, LED depaneling machines, milling cutter-type depaneling machines, and hybrid electrical-electrical design machines use milling cutters for cutting, making them particularly suitable for dividing precision SMD thin boards and aluminum circuit boards. They operate like guillotines and are suitable for PCBs of various thicknesses, with a cutting stroke of less than 2mm, eliminating any concerns about operational safety. They reduce the internal stress generated during cutting to below 180μST, preventing solder cracking and damage to precision components. They can cut V-groove edges with a minimum width of 0.3mm and a height of 60mm. The cutters can be repeatedly re-polished after wear.

[0003] Existing panel separation fixtures typically connect the panels using bolts and other tools, making installation and disassembly cumbersome, time-consuming, and labor-intensive. Therefore, an automatic panel separation machine is needed to improve this problem.

[0004] An existing patent (publication number: CN215471470U) discloses a panel separating fixture for an automatic panel separating machine, comprising a left fixture plate, a rotating shaft connected to the right side of the left fixture plate, and a right fixture plate connected to the outer wall of the rotating shaft. Grooves are formed above and below the center of the front of the left fixture plate, and at positions away from the right fixture plate. A push rod is connected inside the grooves. A through hole is formed on the left side of the grooves, corresponding to the push rod. A button is fixedly connected to the left end of the push rod outside the through hole. A connecting rod is fixedly connected to the outer wall of the push rod on the left side of the left fixture plate. A return spring is fixedly connected to the right end of the push rod inside the groove. By setting up the left fixture plate, right fixture plate, push rod, positioning pin, and limit plate, the problem of the current panel separating fixtures, which are generally connected by bolts and other tools, being cumbersome and time-consuming to install and disassemble, is solved.

[0005] Existing patents offer solutions to the above problems, but they lack a structure for clamping, conveying, and separating the new printed circuit boards, which increases the need for manual intervention, thereby increasing production costs and operational risks.

[0006] Therefore, a new type of automatic PCB separation equipment is proposed. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The PCB depaneling machine body of this application can perform PCB depaneling operations on novel printed circuit boards. It can also support and limit the movement of the support mechanism. The support frame provides stable support for the entire support mechanism and supports and limits the movement of the conveying mechanism. The storage slot provides a temporary space for storing printed circuit boards, allowing users to conveniently place multiple novel printed circuit boards, improving work efficiency. The limiting slot positions the threaded rod and the limiting rod, ensuring they maintain a stable position during operation, thereby ensuring the conveying mechanism can move along a predetermined trajectory, improving the accuracy and stability of PCB depaneling. Driven by a servo motor, the threaded rod can precisely control the moving speed and position of the conveying mechanism, achieving… Precise transport of printed circuit boards ensures accurate separation operations at various positions. Limiting rods provide auxiliary support and guidance, working in conjunction with threaded rods to ensure smooth movement of the transport mechanism, preventing swaying or deviation and improving separation quality. Servo motors provide precise power output, controlling the speed and direction of the threaded rod according to the separation process requirements. Support blocks, as the main support components of the transport mechanism, support important components such as the vacuum pump and adsorption plate, ensuring their stable operation during separation. The left support block is threaded to the threaded rod, while the right support block is slidably connected to the limiting rod, allowing the transport mechanism to move accurately under the guidance of the support mechanism. The vacuum pump provides negative pressure to the adsorption plate via a suction pipe and vacuum hose, enabling the plate to firmly adhere to the printed circuit board (PCB). This ensures the PCB won't shift or fall during transport, improving the safety and stability of the board separation operation. The suction pipe transmits the negative pressure generated by the vacuum pump to the vacuum hose, providing adsorption force to the adsorption plate. The flexible vacuum hose allows the adsorption plate to move up and down with the hydraulic telescopic rod, ensuring the negative pressure is always effectively transmitted to the adsorption plate. The adsorption plate generates adsorption force through adsorption holes at the bottom, firmly adsorbing the PCB and achieving stable transport. The planar structure of the adsorption plate ensures full contact with the PCB, guaranteeing uniform adsorption force. The fabric prevents the circuit board from deforming or being damaged during transport. The suction holes are evenly distributed on the bottom of the suction plate, which can generate uniform suction force to ensure that the printed circuit board remains stable during suction and transport. The hydraulic telescopic rod can adjust the height of the suction plate to adapt to printed circuit boards of different thicknesses, improving the versatility of the equipment. During the separation process, the hydraulic telescopic rod can also adjust the position of the suction plate as needed to ensure the accuracy and reliability of the separation operation. The connecting rod connects the left and right support blocks together to ensure that the conveying mechanism remains synchronized during movement, avoiding the situation where the left and right sides are not synchronized, which may cause the circuit board to tilt or fall. At the same time, the connecting rod also enhances the overall stability of the conveying mechanism.

[0019] 2. Compared with the existing automatic printing circuit board separation equipment, this application achieves the effect of clamping, conveying and separating the new printed circuit board by means of the cooperation of the support mechanism and the conveying mechanism, reducing the need for manual intervention, thereby reducing production costs and operational risks.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A novel automatic printed circuit board separation device includes a separation machine body 1, a support mechanism 2 fixedly connected to the inner side of the separation machine body 1, and a conveying mechanism 3 threadedly connected to the surface of the support mechanism 2.

[0029] The support mechanism 2 includes a support frame 21, a storage plate groove 22, a limiting groove 23, a threaded rod 24, a limiting rod 25, and a servo motor 26. The support frame 21 is fixedly connected to the inner side of the PCB separator body 1. The storage plate groove 22 is opened on the front side of the inner side of the support frame 21. The limiting grooves 23 are respectively opened on both sides of the top of the support frame 21. The threaded rod 24 is rotatably connected to the inner side of the left limiting groove 23. The limiting rod 25 is fixedly connected to the inner side of the right limiting groove 23. The servo motor 26 is bolted to the left side of the front side of the support frame 21. The output end of the servo motor 26 passes through the support frame 21 and is rotatably connected to the support frame 21. The front side of the threaded rod 24 is bolted to the output end of the servo motor 26.

[0030] In this embodiment: the depaneling machine body 1 can depanel new printed circuit boards and support and limit the support mechanism 2. The support frame 21 provides stable support for the entire support mechanism 2 and supports and limits the conveying mechanism 3. The storage slot 22 provides a temporary space for storing printed circuit boards, which can facilitate the user to place multiple new printed circuit boards and improve work efficiency. The limiting slot 23 positions the threaded rod 24 and the limiting rod 25 to ensure that they maintain a stable position during operation, thereby ensuring that the conveying mechanism 3 can move along the predetermined path. The trajectory is used to move, improving the accuracy and stability of the board separation. By setting the threaded rod 24 and driving it with the servo motor 26, the moving speed and position of the conveying mechanism 3 can be precisely controlled, realizing the accurate delivery of printed circuit boards and ensuring that the board separation operation can be carried out accurately in different positions. The limit rod 25 plays an auxiliary support and guiding role, and works with the threaded rod 24 to ensure that the conveying mechanism 3 remains stable during movement without shaking or deviation, thus improving the quality of board separation. By setting the servo motor 26 to provide precise power output, the rotation speed and direction of the threaded rod 24 can be controlled according to the requirements of the board separation process.

[0031] Specifically, such as Figure 3 As shown, the conveying mechanism 3 includes a support block 31, a vacuum pump 32, an air extraction pipe 33, a vacuum hose 34, an adsorption plate 35, several adsorption holes 36, a hydraulic telescopic rod 37, and a connecting rod 38. The left support block 31 is threadedly connected to the surface of the threaded rod 24, and the right support block 31 is slidably connected to the surface of the limiting rod 25.

[0032] Specifically, such as Figure 3 As shown, vacuum pump 32 is bolted to the top of two support blocks 31, suction pipe 33 is fixedly connected to the side of the two vacuum pumps 32 away from each other, suction pipe 33 passes through the top of support block 31 on the side away from vacuum pump 32, vacuum hose 34 is fixedly connected to the bottom of suction pipe 33, and adsorption plate 35 is fixedly connected to the bottom of vacuum hose 34.

[0033] Specifically, such as Figure 3As shown, the adsorption hole 36 is located at the bottom of the adsorption plate 35, the top of the hydraulic telescopic rod 37 is bolted to the bottom of the support block 31, the bottom output end of the hydraulic telescopic rod 37 is bolted to the chamfer at the top of the adsorption plate 35, the left side of the connecting rod 38 is bolted to the front side of the left support block 31, and the right side of the connecting rod 38 is bolted to the front side of the right support block 31.

[0034] In this embodiment: Support block 31 serves as the main support component of the conveying mechanism 3, supporting important components such as vacuum pump 32 and adsorption plate 35, ensuring their stable operation during the board separation process. Simultaneously, the left support block 31 is threadedly connected to threaded rod 24, and the right support block 31 is slidably connected to limiting rod 25, allowing the conveying mechanism 3 to move accurately under the guidance of support mechanism 2. Vacuum pump 32 provides negative pressure to adsorption plate 35 through suction pipe 33 and vacuum hose 34, enabling adsorption plate 35 to firmly adsorb the printed circuit board, ensuring the circuit board will not shift or fall during transport, thus improving the safety and stability of the board separation operation. Suction pipe 33 transmits the negative pressure generated by vacuum pump 32 to vacuum hose 34, providing adsorption force to adsorption plate 35. Vacuum hose 34 has a certain degree of flexibility, adapting to the up-and-down movement of adsorption plate 35 with hydraulic telescopic rod 37, ensuring that negative pressure is always effectively transmitted to adsorption plate 35. The suction plate 35 generates adsorption force through the adsorption holes 36 at the bottom, firmly adsorbing the printed circuit board and achieving stable transport of the circuit board. The planar structure of the adsorption plate 35 ensures full contact with the circuit board, ensuring uniform distribution of adsorption force and preventing deformation or damage to the circuit board during transport. The adsorption holes 36 are evenly distributed at the bottom of the adsorption plate 35, generating uniform adsorption force and ensuring the stability of the printed circuit board during adsorption and transport. The height of the adsorption plate 35 can be adjusted by the hydraulic telescopic rod 37 to accommodate printed circuit boards of different thicknesses, improving the versatility of the equipment. During the board separation process, the hydraulic telescopic rod 37 can also adjust the position of the adsorption plate 35 as needed, ensuring the accuracy and reliability of the board separation operation. The connecting rod 38 connects the left and right support blocks 31 together, ensuring that the transport mechanism 3 remains synchronized during movement and preventing the circuit board from tilting or falling due to asynchrony between the left and right sides. At the same time, the connecting rod 38 also enhances the overall stability of the transport mechanism 3.

[0035] Specifically, such as Figure 4 As shown, a reinforcing ring 4 is bolted to the side of the connecting rod 38 near the support block 31, and the side of the reinforcing ring 4 away from the connecting rod 38 is bolted to the front side of the support block 31.

[0036] Specifically, such as Figure 3 As shown, a protective sleeve 5 is fitted at the bottom of the adsorption hole 36, and the surface of the protective sleeve 5 is coated with an anti-corrosion coating.

[0037] In this embodiment: by setting a reinforcing ring 4, the connection between the connecting rod 38 and the support block 31 is strengthened, improving the stability and firmness of the connection; by setting a protective sleeve 5, the adsorption hole 36 can be prevented from directly contacting the printed circuit board, avoiding scratches or damage to the circuit board; by setting an anti-corrosion coating, it can resist the erosion of various corrosive substances, extend its service life, and reduce the maintenance cost of the equipment.

[0038] Specifically, such as Figure 4 As shown, a reinforcing seat 6 is bolted to the surface of the vacuum pump 32, and the bottom of the reinforcing seat 6 is bolted to the top of the support block 31.

[0039] Specifically, such as Figure 5 As shown, a rotating shaft 7 is bolted to the rear side of the inner side of the left limiting groove 23, and the rear side of the threaded rod 24 is rotatably connected to the inner side of the rotating shaft 7.

[0040] In this embodiment: by setting the reinforcing seat 6, the vacuum pump 32 is reinforced, making the vacuum pump 32 more stable during operation. By setting the rotating shaft 7, during the rotation of the threaded rod 24, the rotating shaft 7 can share some of the force, reducing the burden on the servo motor 26 at the front end of the threaded rod 24 and extending the service life of the servo motor 26.

[0041] Working Principle: First, the user installs the PCB separator body 1 in a suitable working position. Then, when preparing to separate the new printed circuit board, the user places the new printed circuit board to be separated inside the storage box. Subsequently, the user powers on and starts the servo motor 26. The output end of the servo motor 26 drives the threaded rod 24 to rotate. Since the left support block 31 is threadedly connected to the threaded rod 24, and the right support block 31 is slidably connected to the surface of the limit rod 25, under the rotation of the threaded rod 24, the support blocks 31 on both sides begin to move along the preset trajectory through the connecting rod 38. At the same time, the user powers on and starts the vacuum pump 32. The vacuum pump 32 transmits negative pressure to the vacuum hose 34 through the suction pipe 33, thereby causing the adsorption plate 35 to generate adsorption force. In addition, the user powers on and starts the hydraulic telescopic rod 37. The hydraulic telescopic rod 37 drives the adsorption plate 35 to move downward, bringing it close to the top of the new printed circuit board placed inside the storage box. When the suction hole 36 contacts the top of the new printed circuit board, the new printed circuit board will be attracted to the bottom of the suction plate 35 under the action of suction. Then, the user adjusts the height of the suction plate 35 by using the hydraulic telescopic rod 37 to ensure that the new printed circuit board is transported to the bottom of the blade inside the depaneling machine body 1. After the new printed circuit board is depaneled, the user controls the servo motor 26 to reverse, and the servo motor 26 drives the threaded rod 24 to reverse, and the support block 31 will slide backward to the top of the storage box. Then, the user turns off the vacuum pump 32, and the suction force of the suction plate 35 disappears. At this time, the user can remove the depaneled new printed circuit board, and operate the hydraulic telescopic rod 37 to move downward again, and start the vacuum pump 32 to attract the new printed circuit board to be depaneled inside the storage box again. Finally, when all depaneling operations are completed, the user turns off the vacuum pump 32, the hydraulic telescopic rod 37, the servo motor 26 and the depaneling machine body 1 in sequence.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
