Description

Technical Field

[0001] This utility model relates to the field of PCB board production and assembly technology, specifically to a ball bearing guide rail for PCB board production. Background Technology

[0002] In the process of assembling electronic components onto a PCB board, automated equipment is used to ensure assembly efficiency. This assembly equipment includes multiple translation and lifting mechanisms. The translation mechanism uses a slide block and a round rod-shaped guide rail. After a certain number of uses, wear occurs between the slide block and the round rod, resulting in a "flared mouth" phenomenon. This causes the slide block and the round rod to wobble during translation, which seriously affects the assembly of the PCB board and leads to a large number of defective products. Utility Model Content

[0003] To solve the above problems, this utility model provides a ball bearing guide for PCB board production, which adopts a ball bearing slider and guide rail, resulting in stable and precise translation and a long service life.

[0004] The technical solution adopted by this utility model is to provide a ball bearing guide for PCB board production, including a mounting frame, a slide rail disposed in the mounting frame, ball bearing sliders respectively disposed on the slide rail, a mounting plate fixed to the upper end of the ball bearing slider, limiting seats respectively disposed at both ends of the mounting plate, and a limiting groove disposed on the side of the limiting seat facing the mounting frame. Two slide rails are arranged in parallel, and two ball bearing sliders are disposed and slidably mounted on the two slide rails respectively. The inner side of the mounting frame opposite to the limiting seat is embedded in the limiting groove.

[0005] The upper end of the mounting frame is provided with mounting grooves, and the two ends of the slide rail are respectively overlapped and embedded in the mounting grooves and fixed.

[0006] The upper end of the mounting slot and the end facing the inside of the mounting frame are open.

[0007] The beneficial effect of this utility model is that it provides a ball bearing guide for PCB board production, which adopts ball bearing slider and slide rail, greatly reduces friction and wear, and effectively avoids the "trumpet mouth" phenomenon. Attached Figure Description

[0008] Figure 1 It is a structural diagram of the present utility model.

[0009] In the attached diagram, 1 is the mounting frame, 2 is the slide rail, 3 is the ball bearing slider, 4 is the mounting plate, 5 is the limit seat, 6 is the limit groove, and 7 is the mounting groove. Detailed Implementation

[0010] like Figure 1As shown, this utility model provides a ball bearing guide for PCB board production, including a mounting frame 1, a slide rail 2 disposed within the mounting frame 1, ball bearing sliders 3 respectively disposed on the slide rail 2, a mounting plate 4 fixed to the upper end of the ball bearing sliders 3, limiting seats 5 respectively disposed at both ends of the mounting plate 4, and a limiting groove 6 disposed on the side of the limiting seat 5 facing the mounting frame 1. Two slide rails 2 are arranged in parallel, and two ball bearing sliders 3 are disposed and slidably mounted on the two slide rails 2 respectively. The inner side of the mounting frame 1 opposite to the limiting seat 5 is embedded in the limiting groove 6.

[0011] The ball slider 3 and the slide rail 2 are ball-type linear guides. The ball slider 3 contacts the slide rail 2 through the balls. The slide rail 2 is a rectangular structure with ball raceways. When the ball slider 3 slides, the balls inside roll synchronously, which greatly reduces friction and wear and effectively avoids the "trumpet mouth" phenomenon. The use of two sets of ball sliders 3 and slide rails 2 makes the balance of the mounting plate 4 better and more stable when it moves, and increases the upper limit of the structure's stress. Limit seats 5 are added to both ends of the mounting plate 4. The limit seats 5 form a slidable connection with the mounting frame 1 through the limit groove 6 and move synchronously with the mounting plate 4, further improving the balance, stability and upper limit of the stress of the mounting plate 4 when it moves. The mounting plate 4 is used to support and install other mechanisms. It is easy to install and operate.

[0012] like Figure 1 As shown, the upper end of the mounting frame 1 is provided with mounting grooves 7, and the two ends of the slide rail 2 are respectively overlapped and embedded in the mounting grooves 7 and fixed.

[0013] Mounting slot 7 makes positioning the slide rail 2 easier and installation more convenient.

[0014] like Figure 1 As shown, the upper end of the mounting groove 7 and the end facing the inside of the mounting frame 1 are open.

[0015] The structure of the mounting slot 7 is defined, which allows for more precise positioning of the slide rail 2, making installation more convenient.
