Description

Technical Field

[0002] In order to remove dirt, grease, dust, flux residue, rosin residue and other contaminants on the circuit board, the circuit board needs to be cleaned to ensure the performance and reliability of the circuit board. After cleaning, the circuit board needs to be transported for subsequent process flow.

[0003] A Chinese patent application with publication number CN112122196A discloses a circuit board cleaning and conveying device for an assembly line, in which two conveying chains are respectively mounted on two parallel mounting plates, and are driven to operate by a driving sprocket and a driven sprocket rotatably connected at both ends of the mounting plates. The spacing between the two conveying chains is adjusted to enable the chains to lift and convey different circuit boards. When the circuit board moves and passes over a brush roller, the bottom of the circuit board is brushed by the reciprocating brush roller and finally leaves from the other end as the conveyor chain is conveyed. The left and right ends of the device of the present invention can be aligned with the conveying table of the production line without manual intervention.

[0004] In the actual implementation process of the above patent application document, the brush roller rotates to pick up the board washing water in the water box to wash the back of the circuit board. On the one hand, the front of the circuit board cannot be cleaned. On the other hand, since the amount of board washing water picked up by the brush roller is limited and the contact time between the circuit board and the brush roller is also short, the board washing water cannot fully soak and clean the contaminants on the circuit board, resulting in poor cleaning effect.

[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1 to 9 As shown, a switch circuit board conveying device of the present invention comprises a body 1 and a washing liquid pool 2 arranged in the body 1, and the washing liquid pool 2 contains washing liquid for cleaning the circuit board 4. A conveying component 3 is arranged in the washing liquid pool 2, and the conveying component 3 comprises a bracket 31 and a conveying belt 32 arranged on the bracket 31, and push blocks 33 are arranged at intervals on the conveying belt 32, and the circuit board 4 is placed between adjacent push blocks 33. Parts of the bracket 31 and the conveying belt 32 are located in the washing liquid, so that the circuit board 4 on the conveying belt 32 can be fully soaked. The conveying direction of the conveying component 3 is defined as the left-right direction, and a conveying component 2 located on the right side of the conveying component 3 is arranged on the body 1.

[0036] There are two groups of conveying components 2 symmetrically arranged along the front-to-back direction. Conveying components 2 include two sprocket wheels 5 spaced apart from each other and chains 51 arranged around the two sprocket wheels 5. The sprocket wheels 5 are rotatably connected to the machine body 1. The front and rear corresponding sprocket wheels 5 of the two groups of conveying components 2 are fixedly connected through a rotating shaft. The sprocket wheel 5 located at the top is connected to a motor 52. The motor 52 is fixedly mounted on the machine body 1. The motor 52 drives the sprocket wheel 5 to rotate clockwise. Mounting plates 6 are evenly spaced apart on the chain 51. Both ends of the mounting plate 6 are rotatably connected to the corresponding chains 51, and a torsion spring (not shown in the figure) is arranged at the rotating connection. The mounting plate 6 is provided with an avoidance groove 61 for avoiding the conveying component 1 3, which is beneficial for the conveying component 1 3 to transport the circuit board 4 to the mounting plate 6. Sponge structures are arranged on both sides of the mounting plate 6, such as Figure 2 As shown, when the mounting plate 6 is located on the left side of the sprocket 5 and is not acted upon by an external force, the torsion spring drives the mounting plate 6 to be in a state of upward deflection from an end close to the chain 51 to an end away from the chain 51 .

[0037] A driving structure is provided on the machine body 1, and the conveying component 3 conveys the soaked circuit board 4 to the mounting plate 6. The mounting plate 6 picks up the circuit board 4 during the upward movement, and as the chain 51 continues to drive, the two adjacent mounting plates 6 clamp the circuit board 4. When the mounting plate 6 contacts the driving structure, the driving structure drives the mounting plate 6 to deflect downward. When the mounting plate 6 is separated from the driving structure, the mounting plate 6 deflects upward under the action of the torsion spring, thereby realizing that the sponge structure on the two adjacent mounting plates 6 scrubs the circuit board 4, thereby improving the cleaning effect of the circuit board 4.

[0038] A conveyor assembly 3 7 is arranged on the right side of the conveyor assembly 2, and the conveyor assembly 3 7 includes a bracket 2 71 and a conveyor belt 2 arranged on the bracket 2 71. When the mounting plate 6 moves from the top of the sprocket 5 to the right side of the sprocket 5, the circuit board 4 falls onto the conveyor belt 2 and enters the next process flow with the conveyor belt 2. The entire cleaning process does not require manual participation, which avoids the washing liquid from causing harm to the staff.

[0039] like Figures 2 to 5As shown, in order to prevent the circuit board 4 from sliding off the mounting plate 6 after the mounting plate 6 picks up the circuit board 4 from the conveying component 1 3, a guide convex strip 11 is fixedly connected to the machine body 1, and the guide convex strip 11 forms a block for the circuit board 4, so that the circuit board 4 can smoothly rise with the mounting plate 6. The driving structure is located on the left side of the conveying component 2, and the driving structure includes a mounting rod 12 and a protrusion 62. The mounting rod 12 is fixedly connected to the machine body 1, and a lever 13 is evenly arranged at a vertical interval on the side of the mounting rod 12 facing the mounting plate 6, and the protrusion 62 is fixedly connected to the mounting plate 6. When the mounting plate 6 moves upward on the left side of the sprocket 5, the lever 13 pushes the protrusion 62 to drive the mounting plate 6 to deflect downward. When the protrusion 62 is separated from the lever 13, the mounting plate 6 deflects upward under the action of the torsion spring. In the process of repeatedly deflecting downward and upward, the mounting plate 6 causes the sponge structure to repeatedly scrub the surface of the clamped circuit board 4.

[0040] like Figures 5 to 7 As shown, two squeezing plates 8 are symmetrically arranged on both sides of the mounting plate 6. The squeezing plates 8 are parallel to and fixedly connected to the mounting plate 6. A movable plate 9 is arranged between the squeezing plates 8 and the mounting plate 6. The movable plate 9 is slidably arranged in a direction perpendicular to the mounting plate 6. The sponge structure includes a plurality of sponge blocks 91 arranged in a front-to-back direction, and adjacent sponge blocks 91 are fitted front and back toward one end of the circuit board 4. The squeezing plates 8 are provided with squeezing grooves 81 corresponding to the sponge blocks 91. The sponge blocks 91 penetrate the corresponding squeezing grooves 81 and are fixedly connected to the corresponding movable plates 9. The movable plates 9 are connected to a driving assembly for driving the movable plates 9 to move. The protrusions 62 on the mounting plate 6 are disengaged from the uppermost lever 13. When the mounting plate 6 continues to move upward, the driving assembly drives the movable plates 9 to drive the sponge blocks 91 to move in a direction close to the mounting plate 6. The squeezing grooves 81 squeeze the sponge blocks 91, so that the washing liquid in the sponge blocks 91 is squeezed out.

[0041] like Figure 8 As shown, the movable plate 9 is elastically connected to the mounting plate 6 through a spring (not shown in the figure), the driving assembly includes a driving member and a rotating rod 63, the rotating rod 63 is rotatably connected to the mounting plate 6, and the two movable plates 9 are respectively connected to the rotating rod 63 through a connecting rope 92. The driving member drives the rotating rod 63 to rotate and wrap around the connecting rope 92, and the connecting rope 92 drives the corresponding movable plate 9 to move in the direction close to the mounting plate 6. When the driving member cancels the driving of the rotating rod 63, the movable plate 9 moves and resets in the direction away from the mounting plate 6 under the action of the spring. After the washing liquid in the sponge block 91 is squeezed out, the movable plate 9 drives the sponge block 91 to reset, and the sponge block 91 can absorb the washing liquid on the surface of the circuit board 4, which is beneficial to the subsequent drying process of the circuit board 4.

[0042] like Figure 3 and Fig. 9As shown, one end of the mounting plate 6 close to the chain 51 is fixedly connected to a mounting column 67, and the driving member includes a toothed plate 14 fixedly connected to the body 1 and a transmission gear 64 rotatably connected to the mounting column 67, the transmission gear 64 is fixedly connected to a coaxially arranged bevel gear 1 65, and the rotating rod 63 is fixedly connected to a bevel gear 2 66 meshing with the bevel gear 1 65. During the upward movement of the mounting plate 6, when the transmission gear 64 contacts the toothed plate 14, the toothed plate 14 drives the transmission gear 64 to rotate, and the transmission gear 64 drives the rotating rod 63 to rotate through the cooperation of the bevel gear 1 65 and the bevel gear 2 66, so that the rotating rod 63 is wound around the connecting rope 92, driving the movable plate 9 to move in the direction close to the mounting plate 6.

[0043] like Figure 2 and Figure 5 As shown, a support rod 82 perpendicular to the water squeezing plate 8 is fixedly connected to the water squeezing plate 8. When the mounting plate 6 is located on the left side of the sprocket 5, the support rod 82 is located on the upper surface of the water squeezing plate 8, and the support rod 82 is hidden between adjacent sponge blocks 91. When the movable plate 9 drives the sponge block 91 to move closer to the mounting plate 6, the support rod 82 is exposed to support the circuit board 4, which is conducive to the downward flow of the washing liquid squeezed out of the sponge block 91.

[0044] like Figure 5 and Figure 8 As shown, a water bag 10 is arranged between the movable plate 9 and the mounting plate 6, and a nozzle 83 connected to the corresponding water bag 10 is arranged on the water squeezing plate 8. When the movable plate 9 moves toward the mounting plate 6, the water bag 10 is squeezed, and the washing liquid in the water bag 10 is sprayed out from the nozzle 83 to wash the circuit board 4. A water inlet 101 is arranged on the water bag 10, and a one-way valve 1 (not shown in the figure) and a filter screen (not shown in the figure) are arranged at the water inlet 101. The one-way valve 1 allows the washing liquid to enter the water bag 10 from the outside, and the one-way valve 2 (not shown in the figure) is arranged at the nozzle 83. The one-way valve 2 allows the washing liquid in the water bag 10 to flow out. The water bag 10 is bonded to the mounting plate 6 and the corresponding movable plate 9 respectively.

[0045] like Figure 3 , Figure 5 , Figure 8 and Fig. 9As shown, the machine body 1 is provided with a tooth plate 2 15 at a position close to the lower sprocket 5. After the water bag 10 enters the washing liquid pool 2, the transmission gear 64 on the mounting plate 6 meshes with the tooth plate 2 15, and the tooth plate 2 15 drives the transmission gear 64 to rotate. The transmission gear 64 drives the rotating rod 63 to rotate through the cooperation of the bevel gear 1 65 and the bevel gear 2 66. The rotating rod 63 is wound around the connecting rope 92 to drive the movable plate 9 to move toward the mounting plate 6, and the gas in the water bag 10 is discharged through the nozzle 83. After the transmission gear 64 is separated from the tooth plate 2 15 below, the spring resets the movable plate 9, and the movable plate 9 drives the water bag 10 to open, so that the washing liquid in the washing liquid pool 2 is filtered by the filter net and then enters the water bag 10 through the one-way valve 1, so as to replenish the washing liquid in the water bag 10. Moreover, after being filtered by the filter net, the washing liquid entering the water bag 10 is relatively clean, and when the circuit board 4 is flushed, the cleaning effect of the circuit board 4 can be further improved.

[0046] A baffle 53 is fixedly connected to the chain 51 and is located between two adjacent mounting plates 6. When the conveying component 3 conveys the circuit board 4 to the mounting plate 6, the circuit board 4 rests against the baffle 53, which is conducive to unifying the placement position of the circuit board 4 on the mounting plate 6.

[0047] like Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, a guide groove 68 is provided on the mounting column 67. When the mounting plate 6 is located on the left side of the sprocket 5, the guide groove 68 is located on the upper surface of the mounting column 67. The body 1 is fixedly connected with a collecting box 16. When the water squeezing groove 81 squeezes the sponge block 91 and the washing liquid in the water bag 10 washes the circuit board 4, the washing liquid in the sponge block 91 and the washing liquid for washing the circuit board 4 can flow into the collecting box 16 along the guide groove 68, so as to collect the washing liquid, which is beneficial to the subsequent centralized treatment of the washing liquid.
