Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically a deburring component for PCB board processing. Background Technology

[0002] PCB board processing deburring components are equipment components used in the field of PCB board processing technology, specifically designed to remove burrs, sharp edges, and other defects from the edges of PCB boards.

[0003] In PCB manufacturing, deburring is a crucial step. Currently, existing deburring assemblies for PCB manufacturing have several insurmountable shortcomings in practical use. The most prominent problem is the lack of an effective positioning method for PCBs of different sizes. Most existing deburring assemblies can only accommodate PCBs of specific sizes. When processing PCBs of different sizes, frequent manual adjustments of the positioning device are often required, making the operation extremely cumbersome and severely impacting processing efficiency. Therefore, this invention proposes a deburring assembly for PCB manufacturing to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a deburring component for PCB board processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deburring assembly for PCB board processing, comprising a base, on which a positioning fixture mechanism, two sets of support platforms, and a deburring processing mechanism are mounted;

[0006] The positioning fixture mechanism includes a transverse guide seat and a longitudinal guide seat mounted on the base. The longitudinal guide seat is connected to a first cylinder on one side. Two sets of clamping sliders are provided opposite each other on the transverse guide seat. An adjusting slider is provided on the longitudinal guide seat. The two sets of clamping sliders are symmetrically and movably connected to the adjusting sliders through connecting rods. The clamping ends of the two sets of clamping sliders are provided with positioning clips.

[0007] One end of each of the two sets of support platforms is provided with a protruding baffle that matches the positioning clip;

[0008] The deburring processing mechanism includes guide frames mounted on two sets of support platforms. The guide frames are equipped with assembly plates. A second cylinder is mounted below the assembly plates. A grinding motor is mounted below the second cylinder. A deburring grinding block is mounted below the grinding motor.

[0009] Preferably, each of the two sets of support platforms has a screw in its side wall groove. The screw is connected to a control motor on the side wall of the support platform, and the screw is connected to the side blocks at both ends of the guide frame.

[0010] Preferably, a transverse guide cavity is provided above the guide frame, and a lead screw is disposed in the transverse guide cavity. The lead screw is connected to a drive motor on one side of the guide frame, and the lead screw is connected to the assembly plate. The two ends of the assembly plate can move left and right within the range of the two side cavities of the transverse guide cavity.

[0011] Preferably, both the positioning clip and the protruding baffle of the support platform have anti-slip pads attached to their clamping ends by Velcro, and the anti-slip pads are specifically made of rubber.

[0012] Preferably, a positioning hole is provided above the positioning clip, and the positioning clip is detachably installed on the transverse guide by bolts.

[0013] Preferably, a controller is integrated on the side wall of the guide frame, and the controller can be electrically connected to the first cylinder, the control motor, the second cylinder, and the drive motor through PLC programming technology.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The first cylinder controls the longitudinal guide seat, which drives the adjusting slider to move. The connecting rod makes the two sets of clamping sliders move closer or further apart on the transverse guide seat. With the help of the positioning clamps, flexible and precise positioning of PCB boards of different sizes can be achieved, which solves the problem that existing deburring components are difficult to adapt to PCB boards of various sizes, and improves positioning efficiency and accuracy. At the same time, the second cylinder can control the up and down movement of the grinding motor and the deburring block, and adjust the deburring depth and force. The control motor drives the screw to rotate, which enables the guide frame and the deburring processing mechanism mounted on it to move laterally along the support table, realizing deburring operations on different positions of the PCB board. The drive motor drives the lead screw to rotate, which allows the assembly plate to move left and right in the transverse guide cavity, and the transverse position of the deburring block can be flexibly adjusted. The coordinated work of multiple drive methods greatly improves the efficiency and quality of deburring processing. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a PCB board processing deburring assembly, including a base 1, a positioning fixture mechanism 2, two sets of support platforms 3, and a deburring processing mechanism 4 installed on the base 1;

[0023] The positioning fixture mechanism 2 includes a transverse guide seat 21 and a longitudinal guide seat 22 mounted on the base 1. The longitudinal guide seat 22 is connected to a first cylinder 241 on one side. Two sets of clamping sliders 23 are provided opposite each other on the transverse guide seat 21, and an adjusting slider 24 is provided on the longitudinal guide seat 22. The two sets of clamping sliders 23 are symmetrically and movably connected to the adjusting slider 24 through connecting rods 25. The clamping ends of the two sets of clamping sliders 23 are provided with positioning clamps 26. One end of the two sets of support platforms 3 is provided with a protruding baffle that matches the positioning clamps 26. The deburring processing mechanism 4 includes a guide frame 41 mounted on the two sets of support platforms 3. An assembly plate 45 is provided on the guide frame 41. A second cylinder 47 is installed below the assembly plate 45. A grinding motor is installed below the second cylinder 47. A deburring grinding block 48 is installed below the grinding motor.

[0024] Please see Figures 1 to 4Both sets of support platforms 3 have screws 43 installed in the side wall grooves. The screws 43 are connected to the control motors 44 on the side walls of the support platforms 3, and are also connected to the side blocks 42 at both ends of the guide frame 41. A transverse guide cavity is opened above the guide frame 41, and a lead screw 46 is installed in the transverse guide cavity. The lead screw 46 is connected to the drive motor 461 on one side of the guide frame 41, and is also connected to the assembly plate 45. The two ends of the assembly plate 45 can move left and right within the range of the two side cavities of the transverse guide cavity, which can be controlled by the second cylinder 47. The system controls the up-and-down movement of the grinding motor and the deburring block 48 to adjust the deburring depth and force; the system controls the motor 44 to drive the screw 43 to rotate, which enables the guide frame 41 and the deburring processing mechanism 4 mounted on it to move laterally along the support platform 3, realizing deburring operations on different positions of the PCB board; the drive motor 461 drives the lead screw 46 to rotate, which allows the assembly plate 45 to move left and right in the transverse guide cavity, and the transverse position of the deburring block 48 can be flexibly adjusted. Through the coordinated work of multiple drive methods, the efficiency and quality of deburring processing are greatly improved.

[0025] Please see Figures 1 to 4 The positioning clip 26 and the protruding baffle of the support platform 3 both have anti-slip pads attached to their clamping ends with Velcro. The anti-slip pads are made of rubber and utilize the rough surface and elasticity of rubber to significantly increase the friction with the PCB board surface, further preventing the PCB board from sliding. The positioning clip 26 has a pre-drilled positioning hole. The positioning clip 26 is detachably mounted on the transverse guide 21 by bolts. During long-term use, the clamping end of the positioning clip 26 may wear due to frequent contact with the PCB board, affecting the clamping effect. At this time, the operator can use the positioning hole and appropriate tools to quickly unscrew the bolts and remove the worn positioning clip 26 from the transverse guide 21.

[0026] Please see Figures 1 to 4 A controller 5 is integrated on the side wall of the guide frame 41. The controller 5 can be electrically connected to the first cylinder 241, the control motor 44, the second cylinder 47, and the drive motor 461 through PLC programming technology. With the help of PLC programming technology, the controller 5 can issue unified and precise control commands to the first cylinder 241, the control motor 44, the second cylinder 47, and the drive motor 461, so that the operator does not need to manually adjust each power component one by one.

[0027] During positioning, the controller 5 is activated, and the first cylinder 241 is turned on via PLC programming technology. The first cylinder 241 pushes the longitudinal guide 22, causing it to move along the base 1. As the longitudinal guide 22 moves, the adjusting slider 24 mounted on it moves synchronously. The adjusting slider 24 drives two sets of clamping sliders 23 to slide relative to each other on the transverse guide 21 via the connecting rod 25. The operator places the PCB board on the two sets of support platforms 3, so that the edge of the PCB board contacts the protruding baffle at one end of the support platform 3. According to the size of the PCB board, the stroke of the first cylinder 241 is adjusted by the controller 5, thereby precisely adjusting the distance between the two sets of clamping sliders 23. The positioning clamp 26 is used to firmly clamp the PCB board. The rubber anti-slip pads on the clamping end faces of the positioning clamp 26 and the protruding baffle effectively increase friction and prevent the PCB board from sliding during positioning.

[0028] During deburring, based on the location of the PCB board requiring deburring and the process requirements, controller 5 starts control motor 44, which drives screw 43 to rotate. Under the rotation of screw 43, guide bracket 41 moves laterally along the side wall groove of support platform 3, adjusting the deburring processing mechanism 4 to a suitable lateral position. Simultaneously, drive motor 461 is started, driving lead screw 46 to rotate within the lateral guide cavity. Lead screw 46 is connected to assembly plate 45, allowing assembly plate 45 to move left and right within the range of the lateral guide cavity, further fine-tuning the lateral position of deburring block 48. Ensure that the deburring block 48 accurately aligns with the area of ​​the PCB board that needs deburring. Then, the controller 5 starts the second cylinder 47, which pushes downward, causing the grinding motor and the deburring block 48 mounted below to approach the edge of the PCB board. The grinding motor starts, driving the deburring block 48 to rotate at high speed to deburr the edge of the PCB board. It should be noted that the technology of electrically connecting the controller 5 with the first cylinder 241, the control motor 44, the second cylinder 47, and the drive motor 461 through PLC programming is an existing mature technology and will not be described in detail here.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
