Description

Technical Field

[0001] This utility model relates to the field of circuit board processing, specifically to a high-efficiency spraying device for circuit board surface treatment. Background Technology

[0002] A circuit board, also known as a printed circuit board (PCB), is a substrate used for the electrical connection of electronic components in electronic devices. It is usually made of one or more layers of insulating material with copper traces printed on it. These traces connect the various parts of the circuit to form a complete circuit system. Circuit board spraying refers to cleaning circuit boards with water during the manufacturing process by spraying or immersing them to remove dirt and chemicals from the surface, thereby ensuring the performance and reliability of the circuit board.

[0003] Existing spraying devices mostly adopt a fixed station design, which cannot achieve continuous operation. Furthermore, the circuit board positioning method is singular, which can easily cause displacement during the spraying process, resulting in uneven spraying. In particular, it has poor adaptability to irregularly shaped boards, affecting the surface treatment quality. Utility Model Content

[0008] The steering mechanism includes a steering shaft that passes through the vertical plate, one end of which is connected to the output end of the motor, and a rotating frame is sleeved on the outside;

[0010] The adsorption mechanism includes a vacuum generator disposed in the support, and a vacuum suction cup plate that penetrates the spray box partition cavity is mounted on the vacuum generator. The vacuum suction cup plate is provided with a plurality of suction nozzle end seats.

[0011] The spraying mechanism includes a suspension mounted above the track, on which water distribution tanks are installed at intervals, and the output end of the water distribution tanks is connected to a spraying end seat with spray holes.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0026] like Figure 1-3 As shown, the high-efficiency spraying device for circuit board surface treatment proposed in this utility model has a sliding mechanism including symmetrically arranged rails 11, a slidable workstation slide 12 between the two rails 11, a bracket 13 symmetrically installed on the upper part of the workstation slide 12, and a vertical plate 2 installed on the bracket 13.

[0027] The steering mechanism includes a steering shaft 32 that passes through the vertical plate 2. One end of the steering shaft 32 is connected to the output end of the motor 31, and a rotating frame 33 is sleeved on the outside.

[0028] The placement mechanism includes a support 41 that connects to the rotating frame 33, a spray box 42 is mounted on the support 41, and a partition 43 with a partition cavity inside the spray box 42;

[0029] The adsorption mechanism includes a vacuum generator 51 installed in the support 41, a vacuum suction plate 52 that penetrates the partition cavity of the spray box 42 and a number of suction nozzle end seats 53 are provided on the vacuum generator 51.

[0030] The spraying mechanism includes a suspension 61 mounted above the track 11, with water distribution tanks 62 installed at intervals on the suspension 61, and a spraying end seat 63 with spray holes connected to the output end of the water distribution tank 62.

[0031] It should be noted that: at least one workstation slide 12 is set along the transmission direction of the slot in the track 11, and each workstation slide 12 is equipped with an adjustment mechanism and a placement mechanism; multiple workstation slides 12 are set on the track 11, and the workstations are switched by displacement along the slot in the track. The circuit board is placed at the placement mechanism at each workstation, and the circuit board can be continuously processed.

[0032] In this embodiment, when the circuit board surface is treated by spraying, the circuit board is placed in the placement cavity separated by the spray box 42. The circuit board is vacuum-adsorbed by the adsorption mechanism. The vacuum suction cup plate 52 has a planar structure. The vacuum generator 51 adsorbs the gas at the contact position through the suction nozzle end seat 53. The suction nozzle end seat 53 and the contact position of the circuit board back plate form a stable vacuum state, which effectively fixes the circuit board.

[0033] When the workstation slide 12 moves past the spraying mechanism, the treatment liquid in the water tank 62 is sprayed onto the circuit board in the spray box 42 through the spraying end seat 63. Each workstation slide 12 continuously passes through the spraying mechanism to continuously perform surface pretreatment. Subsequently, the rotating frame 33 is controlled by the motor 31 to rotate with the adjusting shaft 32. The rotation angle is 180° clockwise and counterclockwise, adjusting the spray box 42 to the opening facing downwards, separating the excess treatment liquid from the spray box 42, and improving the surface treatment effect of the circuit board. Within one workstation switching cycle, the spraying and drying of the circuit board surface treatment are completed.

[0034] It is understandable that the suspension 61 is fixedly installed above the conveying direction of the workstation slide 12. The water distribution tank 62 and the spray end seat 63 installed on the suspension 61 cooperate with the placement cavity separated in the spray box 42. When each workstation slide 12 passes under the suspension 61, the circuit board in each spray box 42 is sprayed and cleaned through the spray end seat 63.

[0035] To prevent the treatment liquid from remaining in the spray box 42, a through drainage groove 44 is further provided at the bottom of the spray box 42. A gap is left between the drainage groove 44 and the vacuum suction plate 52, through which the treatment liquid is discharged and the newspaper at the vacuum suction plate 52 is dried.

[0036] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
