Description

Technical Field

[0001] The utility model relates to the technical field of PCBA board processing jigs, and specifically relates to a fixture adjusting mechanism for circuit board processing. Background Art

[0002] In the electronic manufacturing industry, the processing of PCBA (Printed Circuit Board Assembly) boards is an important link. As the core component of electronic devices, the processing accuracy and stability of PCBA boards directly affect the performance and reliability of electronic devices. During the processing of PCBA boards, as an important tool for fixing and supporting PCBA boards, the rationality of the fixture design and the adjustment accuracy are crucial for ensuring the processing quality.

[0003] However, there are some problems in the existing jigs for PCBA board processing during actual use. First of all, due to the relatively thin PCBA board itself, traditional jigs often have difficulty providing sufficient clamping force, which easily causes the PCBA board to shift or deform during processing, thus affecting the processing accuracy. Content of the Utility Model

[0004] (I) Purpose of the Utility Model

[0005] In view of this, the purpose of the present utility model is to provide a fixture adjusting mechanism for circuit board processing, which solves the problems raised in the above background.

[0006] (II) Technical Solution

[0007] A fixture adjusting mechanism for circuit board processing includes a housing, the top of the housing is connected with a top shell, and one end of the top shell is connected with a connecting shell. The inner wall of the connecting shell is provided with threads. The inner bottom wall of the housing is fixedly installed with two groups of fixed seats, and circular through grooves are provided on the outer surfaces of the two groups of fixed seats. Bidirectional lead screws are movably installed in the circular through grooves, and one end of each bidirectional lead screw is connected with a motor, and the motor is fixedly connected to one side of the fixed seat. Two groups of sliding seats are movably installed on the outer surfaces of the bidirectional lead screws, and clamping plates are connected to the bottoms of the two groups of sliding seats. An air shell is fixedly installed on the inner wall of the housing, and an air pipe is fixedly installed at the top of the air shell. One end of the air pipe is connected with a vacuum pump, and the vacuum pump is fixedly installed in the inner wall of the top shell. The outer surface of the clamping plate is wrapped with rubber.

[0008] Preferably, a limiting ring is fixedly installed on the inner wall of the top shell.

[0009] Preferably, a storage battery is fixedly installed on one side of the inner wall of the housing, and a charging port is provided on the outer surface of one side of the housing.

[0010] Preferably, a filter plate is fixedly installed at the bottom end of the air shell.

[0011] Preferably, both sides of the inner wall at the bottom end of the outer shell are fixedly installed with limiting sliding rails, and limiting blocks are movably installed in the inner walls of the limiting sliding rails, and the limiting blocks are fixedly connected to one side of the sliding seat.

[0012] Preferably, grooves are formed on the outer surfaces on the upper and lower sides of the limiting blocks, and multiple groups of rotating rollers are movably installed in the grooves.

[0013] Preferably, fixing plates are fixedly installed at the bottom ends of the two fixing seats.

[0014] From the above technical solutions, it can be seen that the present application has the following beneficial effects:

[0015] 1. The utility model can quickly and preliminarily fix the PCBA board on the fixture by using the vacuum adsorption system composed of a vacuum pump and an air shell. This non-contact adsorption method not only avoids the damage to the PCBA board that may be caused by traditional fixtures, but also can provide a stable working position for the PCBA board at the initial stage of processing.

[0016] 2. The utility model drives the bidirectional lead screw to rotate through a motor, and then controls the movement of the sliding seat and the clamping plate, realizing the high-precision clamping of the PCBA board. This clamping method can ensure that the PCBA board maintains a stable position and posture during the processing, improving the processing accuracy. Moreover, the rubber material wrapped on the outer surface of the clamping plate increases the friction with the PCBA board, effectively preventing the PCBA board from sliding or shifting during the processing. At the same time, the rubber material also plays a buffering role, protecting the PCBA board from being clamped and further ensuring the processing quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0025] A fixture adjustment mechanism for circuit board processing, including an outer shell 1, a top shell 2 is connected to the top end of the outer shell 1, and a connecting shell 3 is connected to one end of the top shell 2. Threads are provided on the inner wall of the connecting shell 3. Two groups of fixed seats 612 are fixedly installed on the bottom inner wall of the outer shell 1, and circular through-holes are provided on the outer surfaces of the two groups of fixed seats 612. A bi-directional lead screw 6 is movably installed in each circular through-hole, and one end of the bi-directional lead screw 6 is connected to a motor 611. The motor 611 is fixedly connected to one side of the fixed seat 612. Two groups of sliding seats 7 are movably installed on the outer surface of the bi-directional lead screw 6, and clamping plates 8 are connected to the bottom ends of the two groups of sliding seats 7. An air shell 915 is fixedly installed on the inner wall of the outer shell 1, and an air pipe 913 is fixedly installed at the top end of the air shell 915. One end of the air pipe 913 is connected to a vacuum pump 911. The vacuum pump 911 is fixedly installed in the inner wall of the top shell 2. The outer surface of the clamping plate 8 is wrapped with rubber.

[0026] Furthermore, a limit ring 912 is fixedly installed on the inner wall of the top shell 2. The limit ring 912 is used to support the air shell 915, ensuring the stable support of the air shell 915, preventing it from displacing or shaking during the working process, and thus enhancing the structural stability of the entire fixture.

[0027] Furthermore, a battery 914 is fixedly installed on one side of the inner wall of the outer shell 1, and a charging port 111 is provided on the outer surface of one side of the outer shell 1. The introduction of the battery 914 enables the fixture adjustment mechanism to no longer rely on an external power source for operation, greatly enhancing its portability and independence. The charging port 111 provided on the outer surface of one side of the outer shell 1 facilitates the user to charge the battery 914, ensuring the continuous use of the fixture adjustment mechanism.

[0028] Furthermore, a filter plate 9 is fixedly installed at the bottom end of the air shell 915. The filter plate 9 can prevent dust, impurities, etc. from entering the interior of the air shell, protecting internal components such as the vacuum pump 911 and the air pipe 913 from pollution and damage.

[0029] Furthermore, on both sides of the inner wall at the bottom end of the outer shell 1, limiting sliding rails 5 are fixedly installed, and limiting blocks 711 are movably installed in the inner walls of the limiting sliding rails 5. The limiting blocks 711 are fixedly connected to one side of the sliding seat 7. The limiting sliding rails 5 ensure the linearity and stability of the sliding seat 7 during movement, improving the clamping accuracy and stability.

[0030] Furthermore, grooves are formed on the outer surfaces on the upper and lower sides of the limiting blocks 711, and multiple groups of rotating rollers 712 are movably installed in the grooves. The rotating rollers 712 can significantly reduce the frictional resistance of the sliding seat during movement, making the clamping action smoother and more efficient.

[0031] Furthermore, a fixing plate 4 is fixedly installed at the bottom ends of the two fixing seats 612. The fixing plate 4 enhances the overall structural strength of the fixture adjustment mechanism, making it more durable.

[0032] Working principle: First, the inner wall of the connecting shell 3 is provided with threads. This design enables the fixture mechanism to be conveniently and quickly connected and fixed to other equipment such as a processing machine tool by rotation, thus ensuring the stability of the fixture during the processing. During the process of clamping the PCBA board, first start the vacuum pump 911. The vacuum pump 911 transmits air flow to the air shell 915 through the air pipe 913. As the vacuum pump 911 works, a negative pressure is formed inside the air shell 915, and then suction is generated at the bottom end of the outer shell 1. This suction acts on the PCBA board, enabling it to be tightly adsorbed on one side of the outer shell 1, achieving preliminary fixation. Next, by controlling the start of the motor 611, the bidirectional lead screw 6 connected to the motor 611 starts to rotate. Since threads are respectively provided on both sides of the bidirectional lead screw 6 and are matched with the threads in the two sliding seats 7, when the bidirectional lead screw 6 rotates, the two sliding seats 7 move relatively along the axial direction of the bidirectional lead screw 6. This movement drives the clamping plate 8 connected to the sliding seat 7 to move closer to the middle until the clamping plate 8 clamps the PCBA board on one side of the outer shell 1. The outer surface of the clamping plate 8 is wrapped with a rubber material, increasing the frictional force between the clamping plate 8 and the PCBA board, preventing the PCBA board from sliding or shifting during the processing, and at the same time protecting the PCBA board from being clamped and ensuring the processing quality.
