Description

Technical Field

[0001] This utility model relates to the field of anti-collision device technology, and more specifically, to an anti-collision device for high-end PCBA production process. Background Technology

[0002] Anti-collision devices, as the name suggests, are devices that prevent rigid collisions between objects. They are widely used in automated production equipment. PCBA is a printed circuit board assembly. PCBA is made by printing solder paste on PCB and then installing various components such as resistors, integrated circuits, capacitors and transformers according to the purpose and required characteristics of the circuit board.

[0003] In the PCBA production process, the circuit boards are often limited by pallets and then transported by a conveyor device. During the production and processing of the circuit boards, it is necessary to set up workstations for manual inspection or assembly of some parts in some steps. The pallets carrying the circuit boards are moved from the conveyor belt to the manual inspection table by the workers for manual inspection or assembly of some parts.

[0004] To prevent circuit board trays from colliding during transport, buffer pads or rubber pillars are typically used. However, simple buffer pads or rubber pillars result in a rather rigid cushioning effect, which affects the anti-collision performance. Furthermore, when the tray is removed from or placed on the conveyor belt, it is easy for the tray to collide with the conveyor belt or with the manual inspection table, affecting the installation of components on the circuit board. Therefore, an anti-collision device for high-end PCBA production is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides an anti-collision device in the high-end PCBA production process to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-collision device for high-end PCBA production, comprising a tray, wherein a rubber pad is provided in the middle of the tray, which acts as a buffer when the circuit board is placed in the middle of the tray, preventing the circuit board from colliding with the tray; stabilizing slide strips are symmetrically fixedly connected to the front and rear ends of the tray, facilitating the installation of the tray on the conveyor belt and limiting the position of the tray; anti-collision plates are symmetrically fixedly connected to the left and right ends of the tray, which act as anti-collision when multiple trays are moving, preventing two trays from colliding; a plastic strip is fixedly connected to the middle of the anti-collision plate, which buffers the deformation of the anti-collision plate and improves the anti-collision effect; and multiple rubber blocks are fixedly connected to the side of the anti-collision plate away from the tray, which act as a preliminary buffer and further improve the anti-collision effect.

[0007] An air cushion is fixedly connected to the bottom of the tray, and an elastic strip is fixedly connected to the middle of the air cushion. A buffer plate is provided at the bottom of the tray, and multiple springs are provided at the top of the buffer plate. Multiple positioning posts are fixedly connected to the top of the buffer plate, and a limiting ring is fitted at the top of each positioning post. The air cushion moves the tray from the conveyor belt to the worktable, and acts as a buffer when the tray is placed on the conveyor belt from the worktable. The compression of the springs by the buffer plate further enhances the buffering and anti-collision function. The cooperation of the positioning posts and the limiting rings improves the stability of the buffer plate. The deformation of the air cushion pulls on the elastic strip, thereby deforming the elastic strip and improving the buffering effect.

[0008] Preferably, multiple mounting posts are symmetrically fixedly connected to both ends of the bottom of the rubber pad. One end of each mounting post has a spherical structure. The inner cavity of the tray has a positioning groove corresponding to the mounting post. The mounting posts are located inside the positioning groove. The cooperation between the mounting posts and the positioning groove facilitates the installation and positioning of the rubber pad, so that the rubber pad can be replaced when it is damaged after long-term use, thereby improving the performance.

[0009] Preferably, the anti-collision plate and the plastic strip are made of the same material, the cross-sectional shape of the plastic strip is set to "<", and the two ends of the anti-collision plate are set to beveled structures. Through the cooperation of the anti-collision plate and the plastic strip, deformation occurs during a collision, which plays a buffering role.

[0010] Preferably, the rubber block is fixed to the middle of one side of the anti-collision plate, and the rubber block is set as a cylindrical structure, so as to further play the role of anti-collision.

[0011] Preferably, there are two air cushions, which are respectively set on both sides of the bottom of the tray. The cross-sectional shape of the two ends of the elastic strip is set to "<". Through the cooperation of the air cushions and the elastic strip, the tray plays a buffering role when it is placed, so as to avoid collision during placement.

[0012] Preferably, there are two buffer plates, which are respectively arranged between two air cushions. The top of the spring is fixedly connected to the bottom wall of the tray. The spring is compressed by the buffer plates to achieve a buffering effect.

[0013] Preferably, the limiting ring is fixed to the bottom of the tray, and the top of the positioning post extends into the interior of the limiting ring and is fixedly connected to the limiting plate. The cooperation between the limiting ring and the positioning post improves the stability of the buffer plate's movement.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model firstly uses a rubber pad to cushion the circuit board when it is placed in the middle of the tray, preventing the circuit board from colliding with the tray. The combination of the anti-collision plate and the plastic strip causes the anti-collision plate and the plastic strip to deform when two adjacent trays collide, which also cushions the circuit and makes the cushioning effect more gradual and improves the cushioning effect. The combination of the air cushion and the elastic strip makes the tray cushion when it is placed, preventing collisions. The compression of the spring by the buffer plate further improves the cushioning effect, preventing collisions with the conveyor belt or manual inspection table and improving the protection effect.

[0016] 2. This utility model also improves the stability of the buffer plate's movement by using the combination of the limiting ring and the positioning post. The combination of the mounting post and the positioning groove facilitates the installation and positioning of the rubber pad, so that the rubber pad can be replaced when it is damaged after long-term use, thus improving the performance. The rubber block plays a preliminary buffering role, further improving the anti-collision effect. The plastic strip buffers the deformation of the anti-collision plate, improving the anti-collision effect.

[0017] In summary, through the interaction of the above-mentioned multiple functions, the collision between two adjacent pallets can be buffered, and the buffering effect can be made more gradual, thus improving the buffering effect. Furthermore, buffering during pallet placement can prevent collisions with the conveyor belt or manual inspection table, thereby improving the protective effect. Attached Figure Description

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.

[0025] As attached Figure 1-5 The diagram shows an anti-collision device for high-end PCBA production, including a tray 1. A rubber pad 2 is provided in the middle of the tray 1. When the circuit board is placed in the middle of the tray 1, the rubber pad 2 acts as a buffer to prevent the circuit board from colliding with the tray 1. Stabilizing slide strips 3 are symmetrically fixed to the front and rear ends of the tray 1 to facilitate the installation of the tray 1 on the conveyor belt and to limit the movement of the tray 1. Anti-collision plates 4 are symmetrically fixed to the left and right ends of the tray 1. The anti-collision plates 4 can prevent collisions when multiple trays 1 are moving, preventing two trays 1 from colliding. A plastic strip 13 is fixedly connected to the middle of the anti-collision plate 4. The plastic strip 13 buffers the deformation of the anti-collision plate 4 and improves the anti-collision effect. Multiple rubber blocks 5 are fixedly connected to the side of the anti-collision plate 4 away from the tray 1. The rubber blocks 5 act as a preliminary buffer to further improve the anti-collision effect.

[0026] An air cushion 6 is fixedly connected to the bottom of the pallet 1, and an elastic strip 7 is fixedly connected to the middle of the air cushion 6. A buffer plate 8 is provided at the bottom of the pallet 1, and multiple springs 9 are provided at the top of the buffer plate 8. Multiple positioning posts 10 are fixedly connected to the top of the buffer plate 8, and a limiting ring 11 is sleeved on the top of the positioning post 10. The air cushion 6 moves the pallet 1 from the conveyor belt to the worktable and acts as a buffer when it is placed on the conveyor belt from the worktable. The compression of the springs 9 by the buffer plate 8 further enhances the buffering and anti-collision function. The cooperation of the positioning posts 10 and the limiting ring 11 improves the stability of the buffer plate 8. The deformation of the air cushion 6 pulls on the elastic strip 7, thereby deforming the elastic strip 7 and improving the buffering effect.

[0027] As attached Figure 1-5As shown, multiple mounting posts 12 are symmetrically fixed to both ends of the bottom of the rubber pad 2. One end of each mounting post 12 has a spherical structure. The inner cavity of the tray 1 has a positioning groove corresponding to the mounting post 12. The mounting posts 12 are placed inside the positioning groove. The anti-collision plate 4 and the plastic strip 13 are made of the same material. The cross-sectional shape of the plastic strip 13 is "<". Both ends of the anti-collision plate 4 are beveled. The rubber block 5 is fixed to the middle of one side of the anti-collision plate 4. The rubber block 5 is cylindrical. There are two air cushions 6, which are respectively set on both sides of the bottom of the tray 1. The cross-sectional shape of both ends of the elastic strip 7 is "<". There are two buffer plates 8, which are respectively set between the two air cushions 6. The top of the spring 9 is fixed to the bottom wall of the tray 1. Next, the limiting ring 11 is fixed to the bottom of the tray 1, and the top of the positioning post 10 extends into the interior of the limiting ring 11 and is fixedly connected to the limiting plate. Through the cooperation of the mounting post 12 and the positioning groove, the rubber pad 2 is conveniently installed and positioned, so that the rubber pad 2 can be replaced when it is damaged after long-term use, thus improving the performance. Through the cooperation of the anti-collision plate 4 and the plastic strip 13, deformation occurs during collision, which plays a buffering role. The rubber block 5 further plays a collision-proof role. Through the cooperation of the air cushion 6 and the elastic strip 7, the tray 1 plays a buffering role when placed, avoiding collisions during placement. The compression of the spring 9 by the buffer plate 8 plays a buffering role. Through the cooperation of the limiting ring 11 and the positioning post 10, the stability of the buffer plate 8 in buffering movement is improved.

[0028] The working principle of this utility model is as follows: When the circuit board is placed in the middle of the tray 1, it can be cushioned by the rubber pad 2 to avoid collision between the circuit board and the bottom wall of the tray 1.

[0029] When multiple pallets 1 are conveyed on the conveyor belt, the anti-collision plates 4 and rubber blocks 5 at both ends of the pallets 1 provide buffer protection to prevent two adjacent pallets 1 from colliding, thereby affecting the conveying effect of the circuit board in the middle of the pallet 1.

[0030] When the pallet 1 carrying the circuit board needs to be manually moved from the conveyor belt to the manual inspection platform, or when the pallet 1 is placed on the conveyor belt, the air cushion 6 and the buffer plate 8 are squeezed, causing the buffer plate 8 to squeeze the spring 9, which can buffer the pallet 1 when it is placed, improve the stability of the placement, and improve the anti-collision effect.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
