Description

Technical Field

[0001] This utility model relates to the field of circuit board processing equipment technology, specifically a circuit board connection platform. Background Technology

[0002] In surface mount technology (SMT) production lines, the feeder platform plays a crucial role as a buffer and transmission mechanism connecting different production equipment. It is primarily used to receive, temporarily store, and transport circuit boards (PCBs), ensuring the continuity and stability of the production line process.

[0003] Currently, most conveyor belt docking stations on the market employ an adjustable conveyor belt spacing design to accommodate circuit boards of different sizes. For example, Chinese utility model patent CN214086495U discloses a docking station for SMT assembly. This docking station uses drive components such as lead screws and sprockets to move a slider, thereby adjusting the distance between the first and second conveying devices. This effectively improves the equipment's adaptability to PCBs of different specifications and solves the problem of fixed conveyor width.

[0004] However, after in-depth research and practice, the inventors discovered a significant but overlooked flaw in the practical application of such adjustable-gap connecting platforms: the sides of the circuit boards are prone to friction and scratches against the equipment's fixed frame. Specifically, to enable the conveyor belt to be adjustable, a clearance must exist between it and the outer fixed side plate or equipment frame. During transmission, due to equipment vibration, circuit board dimensional tolerances, or installation errors, the sides of the circuit board are highly susceptible to deviating from the ideal transmission path, resulting in contact and sliding friction with the fixed frame (such as the connecting plate in patent CN214086495U). This friction not only leaves scratches on the edges of the circuit board, damaging its appearance and integrity, but more seriously, it can cause damage or scrapping of precision components on the board's edge, directly leading to product scrap and economic losses in production.

[0005] Therefore, we propose a circuit board connector. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a circuit board connecting platform. By setting a synchronously running flexible guard with ball bearings on the outside of the conveyor belt, it can fundamentally prevent the sides of the circuit board from being scratched, and significantly reduce running resistance and wear through rolling friction, thus effectively solving the problems in the background technology.

[0007] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: a circuit board connecting platform, including a connecting platform and two parallel conveying devices with adjustable spacing disposed on the connecting platform. An annular baffle is fixedly installed on the outer edge of the working surface of the conveyor belt in the conveying device. A ball bearing seat is embedded and fixedly installed on the outer wall of the annular baffle. A ball bearing seat is provided in the ball bearing seat, which contains freely rotatable balls. Anti-slip texture is provided on the inner wall of the conveyor belt.

[0008] Preferably, the annular retaining edge is a flexible retaining edge made of rubber or polyurethane.

[0009] Preferably, the annular retaining edge is fixed to the conveyor belt by bonding or integral molding with the conveyor belt.

[0010] Preferably, a portion of the spherical surface of the ball protrudes from the ball seat and rolls in contact with the inner side of the fixed frame of the conveying device.

[0011] Preferably, the ball bearing seats are evenly spaced along the circumference of the annular retaining edge.

[0012] Preferably, the ball is a stainless steel ball, a ceramic ball, or an engineering plastic ball.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a circuit board connector platform, which has the following advantages: 1. This circuit board connecting platform provides a "dynamic guardrail" for the side of the circuit board without relative sliding by setting a synchronously moving annular guardrail on the outer edge of the conveyor belt working surface; when the circuit board is offset, its side contacts the synchronously moving flexible guardrail instead of the stationary metal frame, thereby eliminating scratches, wear and component damage on the side of the circuit board from the source and improving the product yield.

[0014] 2. The circuit board connector has a ball bearing and ball bearing seat structure on the outer wall of the annular retaining edge; this structure transforms the traditional harmful sliding friction into low-resistance rolling friction when the annular retaining edge contacts the fixed frame of the equipment.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a circuit board connection platform, including a connection platform 1 and two parallel conveyor devices 2 with adjustable spacing disposed on the connection platform 1. The spacing adjustment of the conveyor devices 2 can be achieved by existing technologies such as screw and nut mechanisms and linear guides, which are conventional designs and will not be described in detail here. The core component of each conveyor device 2 is an annular conveyor belt 3, which is tensioned and driven to circulate by a drive roller and a driven roller.

[0022] An annular retaining edge 5 is fixedly installed on the outer edge of the working surface of the conveyor belt 3 (i.e., the outer side of the upper surface that carries the circuit board and operates in contact with it). This annular retaining edge 5 is preferably made of a flexible material such as rubber or polyurethane, possessing good elasticity and wear resistance. The annular retaining edge 5 can be firmly bonded to the conveyor belt 3 with adhesive, or, to obtain better connection strength and service life, it can be fixed by integral molding with the conveyor belt 3 (e.g., manufactured simultaneously during the vulcanization molding of the conveyor belt 3).

[0023] The main function of the annular retaining edge 5 is to form a continuous, flexible barrier on the outside of the circuit board's transport path, moving synchronously with the conveyor belt 3. When the circuit board shifts laterally during transport due to jitter, tolerances, or installation errors, its side edge first contacts the synchronously moving annular retaining edge 5, rather than the fixed frame of the connecting platform (such as stationary components like side panels or support beams). Because the annular retaining edge 5 moves synchronously with the conveyor belt 3, there is almost no relative sliding between it and the side of the circuit board, effectively avoiding scratches, wear, and the risk of damage to components on the board edge.

[0024] To further optimize the operating performance of the annular retaining edge 5, multiple ball bearing seats 8 are embedded and fixedly installed on the outer wall of the annular retaining edge 5 (i.e., the side facing away from the circuit board and towards the fixed frame of the conveyor device 2). These ball bearing seats 8 are preferably evenly spaced along the circumference of the annular retaining edge 5 to ensure uniform support and force distribution. Each ball bearing seat 8 contains a freely rotatable ball 7. The material of the ball 7 can be selected as needed, such as stainless steel (wear-resistant, good load-bearing capacity), ceramic (high hardness, corrosion-resistant), or engineering plastics (e.g., self-lubricating, low noise).

[0025] Part of the spherical surface of the ball 7 protrudes from the ball seat 8 and rolls into contact with the fixed frame of the conveyor device 2 (e.g., the inner surface of a side guide rail or fixed side plate used to support and guide the conveyor belt). This design transforms the potentially harmful sliding friction that might occur if the flexible baffle comes into contact with the fixed frame in a conventional structure into low-resistance rolling friction. This reduces the frictional resistance and wear of the annular baffle 5 during operation, ensuring not only the smooth operation and driving efficiency of the conveyor belt 3, but also extending the service life of the annular baffle 5 and its contact components.

[0026] In addition, anti-slip textures 4 are provided on the inner wall of the conveyor belt 3 (i.e., the inner surface that contacts the drive roller, driven roller, and tension roller). These anti-slip textures 4 can be regular raised stripes, dotted bumps, or other textures that increase friction. The anti-slip textures 4 effectively increase the friction between the conveyor belt 3 and the drive roller, preventing the conveyor belt 3 from slipping on the drive roller and ensuring accurate and synchronized transmission speed.

[0027] The working principle of this utility model is as follows: In use, adjust the spacing between the two conveyor devices 2 according to the width of the circuit board to be transferred. Start the docking station; the drive mechanism of the conveyor device 2 drives the conveyor belt 3 to rotate cyclically. The circuit board is placed on the two conveyor belts 3, which carry it forward. The annular retaining edge 5 moves synchronously with the conveyor belt 3, forming dynamic protection on both sides of the circuit board. If the circuit board deviates to the side, its side contacts the flexible retaining edge to prevent scratching against the fixed frame. Simultaneously, the ball bearings 7 on the outer wall of the annular retaining edge 5 form rolling support with the inner side of the fixed frame, ensuring low-resistance operation. The anti-slip texture 4 on the inner wall of the conveyor belt 3 ensures the reliability of the transmission.
