AI Technical Summary
Existing PCB board mounting fixtures are prone to PCB board vibration during soldering, causing the PCB board to bounce out and have poor heat dissipation, which affects production quality.
A PCB board mounting fixture including a fixture body and a pneumatic base is designed. The pneumatic base drives a clamping mechanism to clamp the PCB board, and a support beam and a return hole are set in the positioning groove of the fixture to improve stability and heat dissipation.
It achieves stable positioning of the PCB board and improves heat dissipation, reduces the investment cost for enterprises, and prevents the PCB board from slipping and getting damaged.

Abstract
Claims
1. A PCB board paster jig comprising a jig body, characterized in that: It also includes a pneumatic base. The fixture body has a hollow fixture positioning groove in the middle, and a support frame is provided in the fixture positioning groove. Several return holes are provided around the fixture positioning groove. The fixture body also has multiple sets of clamping mounting grooves. Each set of clamping mounting grooves includes two symmetrically arranged clamping mounting grooves. Each clamping mounting groove is provided with a clamping mechanism. The clamping mechanism includes a spring and a T-shaped clamping block. One end of the spring abuts against the T-shaped clamping block, and the other end abuts against the side wall of the clamping mounting groove. The pneumatic base includes a drive mechanism and a telescopic bracket. The drive mechanism is used to drive the telescopic bracket to open and close. The telescopic bracket is used to cooperate with the clamping mechanism of the fixture body.
2. The PCB board paster jig according to claim 1, characterized in that: The clamping surface of the T-shaped clamping block is provided with several friction teeth.
3. The PCB board paster jig according to claim 1, wherein: The fixture positioning groove is provided with multiple crisscrossing support beams to form a support frame.
4. The PCB board paster jig according to claim 1, characterized in that: The fixture has a circumferential return hole on the inner side of the positioning groove.
5. The PCB board paster jig according to claim 1, wherein: Each of the clamping mounting slots has an inwardly bent limiting part on both sides.
6. The PCB board paster jig according to claim 1, wherein: The telescopic bracket includes two pressure plates and two telescopic plates. The pressure plates are connected to the telescopic plates, and the two telescopic plates are located between the two pressure plates. The telescopic plates have inclined strip-shaped adjustment holes. A connecting plate is provided between the two telescopic plates. The two ends of the connecting plate have protrusions that slide with the strip-shaped adjustment holes. The middle part of the connecting plate is connected to the movable end of the driving mechanism. The driving mechanism is used to drive the protrusions of the connecting plate to move along the adjustment holes.
7. The PCB board paster jig according to claim 6, characterized in that: The pneumatic base is also provided with a base and a guide rod. The guide rod and the drive mechanism are fixed on the base, and the pressure plates on both sides of the telescopic bracket are respectively sleeved on the guide rod.
8. The PCB board paster jig according to claim 6, wherein: Each of the telescopic plates has two inclined strip-shaped adjustment holes.
9. The PCB board paster jig according to claim 1, wherein: The fixture body is also provided with four sets of clamping slots.
