Description

Technical Field

[0001] The invention relates to the technical field of electronic component cleaning, in particular to an electrical component cleaning system. Background Art

[0002] It is very common to use air to clean electrical components. In addition to air, dry ice gas can also be used. In view of the complex spatial state of the circuit board, it is easier to use gas cleaning to remove stubborn stains in the gaps. However, due to the complex spatial structure of the circuit board, stubborn stains are easily left in a certain gap area after being blown away. Since the wind direction is mostly vertical to the circuit board, the dispersed wind direction is fixed at this time, and the dirt remaining in the gap area is difficult to get rid of. Summary of the invention

[0003] The object of the present invention is to provide an electrical component cleaning system to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] An electrical component cleaning system comprises a lotus-type circuit board clamping module and a matrix-type jet module, wherein the lotus-type circuit board clamping module clamps and conveys the circuit board to the matrix-type jet module, and the matrix-type jet module controls the circuit board on the top surface of the lotus-type circuit board clamping module to be blown and cleaned;

[0006] The lotus-type circuit board clamping module includes a sliding seat as a base and a supporting column fixed in the middle of the sliding seat, sliders connected to the track are arranged on both sides of the sliding seat, the top of the supporting column is rotatably connected to a cleaning fixed platform through a traction universal joint, and four clamps are arranged on the top of the cleaning fixed platform;

[0007] The support column is driven and rotated by a rotation driving unit with a T-shaped pushing unit, the side end of the T-shaped pushing unit is fitted with the wave surrounding unit, the wave surrounding unit is fixedly connected to the top of the sliding seat, and realizes up and down movement during the rotation process, and the top of the T-shaped pushing unit is fitted with the cleaning fixed platform to drive the cleaning fixed platform to continuously change direction and tilt.

[0008] As a further solution of the present invention: a sleeve is rotatably connected to the support column, a horizontal support sleeve rod is fixedly connected to the side of the sleeve, the rotation drive unit is installed on the side of the support column, the rotation drive unit drives the sleeve to rotate, the vertical part of the T-shaped push unit is sleeved on the circular hole of the horizontal support sleeve rod, and the horizontal support sleeve rod and the T-shaped push unit are elastically connected by a spring.

[0009] As a further solution of the present invention: a ball is arranged on the top of the T-shaped pushing unit.

[0010] As a further solution of the present invention: a plurality of evenly distributed traction elastic ropes are arranged on the traction type universal joint.

[0011] As a further solution of the present invention: the rotary drive unit, the wave encirclement unit and the T-shaped push unit are removed, and the matrix jet module is composed of a plurality of partitioned jet units, each of which has a wind pressure controlled by a wind pressure adjustment unit, and the wind pressure adjustment unit is centrally controlled by a controller, and the partitioned jet units form different blowing speeds, so that the cleaning fixed platform is unevenly force-bearing and tilted, and the cleaning fixed platform is changed and tilted by changing the wind pressure adjustment unit.

[0012] As a further solution of the present invention: the wind pressure adjustment unit is replaced with a solenoid valve, the controller controls the opening and closing of the solenoid valve, and the partitioned jet unit is used to spray in a biased manner on the surface of the cleaning fixed platform, so that the cleaning fixed platform changes direction and tilts.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. A wave-enclosing unit is fixed around the top of the sliding seat. After the support column raises the height of the cleaning fixed platform, when the cleaning fixed platform is tilted to the extreme angle, it will not contact and cooperate with the high point of the wave-enclosing unit to avoid structural interference. At the same time, the traction universal joint can play a movable connection role for the cleaning fixed platform. The traction universal joint provides a higher degree of freedom of movement for the cleaning fixed platform, so that the tilt direction of the cleaning fixed platform can be continuously changed. At this time, the wind direction blown out by the matrix jet module is fixed. As the angle of the cleaning fixed platform changes, the contact angle between the circuit board and the wind is constantly changing, thereby promoting the faster shedding of dust in the gap. Under the influence of the tilt, the dust can be fully affected by gravity and fall.

[0015] 2. First, the traction universal joint is set at the center of the cleaning fixed platform. When the pressure blown out by the partitioned jet unit corresponding to the area on the surface of the cleaning fixed platform located on one side of the traction universal joint is high, the corresponding point of the cleaning fixed platform is the lowest point, and the area height of the cleaning fixed platform corresponding to other partitioned jet units with low pressure is increased. Therefore, by controlling in this way, not only the direction of the cleaning fixed platform can be changed, but also the circuit board on the top of the cleaning fixed platform is in a fully wind-received state, thereby improving the cleaning effect.

[0016] 3. Based on advantage 2, it is only necessary to replace the air pressure adjustment unit with a solenoid valve, so that the air pressure adjustment unit is opened independently one at a time, thereby reducing the use of gas. During each blowing process, the circuit board on the blowing surface of the air pressure adjustment unit is in an inclined state, so that dust can fall to the bottom more easily. Furthermore, the interior of the sliding seat can be changed to a storage filter to store the filtered dirt and impurities. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-Figure 8 :

[0028] Embodiment 1:

[0029] It includes a lotus-type circuit board clamping module 1 and a matrix-type jet module 2. The lotus-type circuit board clamping module 1 clamps and transports the circuit board to the matrix-type jet module 2. The matrix jet module 2 controls the blowing and cleaning of the circuit board on the top surface of the lotus-type circuit board clamping module 1. The lotus-type circuit board clamping module 1 includes a sliding seat 14 as a base and a supporting column 15 fixed in the middle of the sliding seat 14. Slide blocks 141 connected to the track are arranged on both sides of the sliding seat 14. The top of the supporting column 15 is rotatably connected to a cleaning fixed platform 17 through a traction universal joint 16. Four clamps 171 are arranged on the top of the cleaning fixed platform 17. The supporting column 15 is driven to rotate and connected to a T-shaped pushing unit 13 through a rotating driving unit 11. The side end of the T-shaped pushing unit 13 is fitted with the wave surrounding unit 12 The wave enveloping unit 12 is fixedly connected to the top of the sliding seat 14, and realizes up and down movement during the rotation process. The top of the T-shaped pushing unit 13 fits with the cleaning fixed platform 17 to drive the cleaning fixed platform 17 to continuously change direction and tilt. The support column 15 is rotatably connected with a sleeve 131, and the side of the sleeve 131 is fixedly connected with a horizontal support sleeve rod 132. The rotation driving unit 11 is installed on the side of the support column 15. The rotation driving unit 11 drives the sleeve 131 to rotate. The vertical part of the T-shaped pushing unit 13 is sleeved on the circular hole of the horizontal support sleeve rod 132. The horizontal support sleeve rod 132 is elastically connected to the T-shaped pushing unit 13 through a spring 133. A ball is arranged on the top of the T-shaped pushing unit 13, and a plurality of evenly distributed traction elastic ropes 161 are arranged on the traction universal joint 16.

[0030] In this embodiment: the shape of the lotus-shaped circuit board clamping module 1 is similar to a lotus. First, the sliding seat 14 is the base seat. According to the production line requirements, the sliding seat 14 can cooperate with the guide rail to achieve directional movement. The support column 15 mainly raises the height of the cleaning fixed platform 17. The wave surrounding unit 12 is fixed around the top of the sliding seat 14. After the support column 15 raises the height of the cleaning fixed platform 17, when the cleaning fixed platform 17 is tilted to the extreme angle, it will not contact and cooperate with the high point of the wave surrounding unit 12 to avoid structural interference. At the same time, the traction universal joint 16 can play a movable connection role for the cleaning fixed platform 17. The traction universal joint 16 provides a higher degree of freedom of movement for the cleaning fixed platform 17, so that the tilt direction of the cleaning fixed platform 17 is constantly changed. At this time, the wind direction blown out by the matrix jet module 2 is fixed. Due to the change in the angle of the cleaning fixed platform 17, the contact angle between the circuit board and the wind is constantly changing, thereby promoting the dust in the gap to fall off more quickly. Under the influence of the tilt, the dust can be fully affected by gravity and fall.

[0031] In this embodiment: the traction elastic rope 161 is used to pull the traction universal joint 16, which can not only avoid the axial spin problem of the traction universal joint 16, but also realize the reset function after the angle of the cleaning fixed platform 17 changes. Since the corresponding point between the bottom of the cleaning fixed platform 17 and the wave surrounding unit 12 changes after the cleaning fixed platform 17 tilts, a completely new structure is required, so a T-shaped push unit 13 is set. First, the T-shaped push unit 13 is T-shaped, and the cross bar of the T-shaped push unit 13 contacts the wave surrounding unit 12, and the vertical bar of the T-shaped push unit 13 contacts the top of the cleaning fixed platform 17, and a ball is set on the top of the vertical bar of the T-shaped push unit 13. The ball contacts and rotates with the cleaning fixed platform 17 to reduce friction, and the cross bar will continuously contact the wave surrounding unit 12. The high and low points of the cleaning and fixing platform 17 are in contact to form vertical fluctuations, and the T-shaped pushing unit 13 can lift one side of the cleaning and fixing platform 17. At this time, the spring 133 undergoes elastic deformation to ensure that the cross bar of the T-shaped pushing unit 13 is always in contact with the wave surrounding unit 12. At the same time, the traction elastic rope 161 undergoes elastic deformation, thereby cooperating with the T-shaped pushing unit 13 to make the cleaning and fixing platform 17 achieve tilt balance. As the T-shaped pushing unit 13 rotates, the tilt high point of the cleaning and fixing platform 17 changes in a circular motion, thereby constantly changing the contact angle between the circuit board and the wind, so that the dirt can fall off quickly.

[0032] In this embodiment: the sleeve 131 is driven to rotate by the rotation drive unit 11, thereby driving the horizontal support sleeve rod 132 to rotate. Based on the circular hole, the T-shaped push unit 13 can slide up and down on the horizontal support sleeve rod 132, thereby satisfying the dynamic tilting movement of the cleaning fixed platform 17.

[0033] Embodiment 2:

[0034] The invention comprises a lotus-type circuit board clamping module 1 and a matrix-type jet module 2. The lotus-type circuit board clamping module 1 clamps and transports the circuit board to the matrix-type jet module 2. The matrix jet module 2 controls the blowing of air toward the circuit board on the top surface of the lotus-type circuit board clamping module 1 for cleaning. The lotus-type circuit board clamping module 1 comprises a sliding seat 14 as a base and a supporting column 15 fixed in the middle of the sliding seat 14. Slide blocks 141 connected to the track are arranged on both sides of the sliding seat 14. The top of the supporting column 15 is rotatably connected to a cleaning fixed platform 17 through a traction universal joint 16. The cleaning fixed platform Four clamps 171 are arranged on the top of the platform 17, a ball bearing is arranged on the top of the T-shaped push unit 13, a plurality of evenly distributed traction elastic ropes 161 are arranged on the traction universal joint 16, and the matrix jet module 2 is composed of a plurality of partitioned jet units 21, each partitioned jet unit 21 is controlled by a wind pressure adjustment unit 22 for wind pressure, and the wind pressure adjustment unit 22 is centrally controlled by a controller 23, and the partitioned jet unit 21 forms different blowing speeds, so that the cleaning fixed platform 17 is unevenly tilted due to force, and the cleaning fixed platform 17 is changed and tilted by changing the wind pressure adjustment unit 22.

[0035] In this embodiment: after the rotation drive unit 11 and the T-shaped pushing unit 13 are removed, the cleaning fixed platform 17 can achieve balance only under the cooperation of the traction elastic rope 161 and the traction universal joint 16, so the inclination of the cleaning fixed platform 17 can be controlled by changing the pressure in different wind direction areas.

[0036] In the present embodiment: first, the traction universal joint 16 is arranged at the center of the cleaning fixed platform 17. When the pressure blown out by the partitioned jet unit 21 corresponding to the area on the surface of the cleaning fixed platform 17 located on one side of the traction universal joint 16 is high, the corresponding point of the cleaning fixed platform 17 is the lowest point at this time, while the area height of the cleaning fixed platform 17 corresponding to other partitioned jet units 21 with low pressure is increased. Therefore, by controlling in this way, not only the direction of the cleaning fixed platform 17 can be changed, but also the circuit board on the top of the cleaning fixed platform 17 is in a fully wind-received state, thereby improving the cleaning effect.

[0037] Embodiment three:

[0038] It includes a lotus-type circuit board clamping module 1 and a matrix-type jet module 2. The lotus-type circuit board clamping module 1 clamps and transports the circuit board to the matrix-type jet module 2. The matrix jet module 2 controls the blowing and cleaning of the circuit board on the top surface of the lotus-type circuit board clamping module 1. The lotus-type circuit board clamping module 1 includes a sliding seat 14 as a base and a supporting column 15 fixed in the middle of the sliding seat 14. Slide blocks 141 connected to the track are arranged on both sides of the sliding seat 14. The top of the supporting column 15 is rotatably connected to a cleaning fixed platform 17 through a traction universal joint 16. Four clamps 171 are arranged on the top of the cleaning fixed platform 17, a ball bearing is arranged on the top of the T-shaped pushing unit 13, a plurality of evenly distributed traction elastic ropes 161 are arranged on the traction type universal joint 16, and the matrix jet module 2 is composed of a plurality of partitioned jet units 21, each partitioned jet unit 21 is connected to the air circuit by an electromagnetic valve, and the electromagnetic valve is centrally controlled by the controller 23, and the partitioned jet unit 21 forms different blowing areas, so that the cleaning fixed platform 17 is unevenly tilted due to the force, and the cleaning fixed platform 17 is tilted in a different direction by changing the connection of the electromagnetic valve.

[0039] In this embodiment, it is only necessary to replace the air pressure adjustment unit 22 with a solenoid valve, so that the air pressure adjustment unit 22 is opened independently at a time, thereby reducing the use of gas. During each blowing process, the circuit board on the blowing surface of the air pressure adjustment unit 22 is in an inclined state, so that dust can fall to the bottom more easily. Furthermore, the interior of the sliding seat 14 can be changed to a storage filter to store the filtered dirt and impurities.
