It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] like Figures 1 to 5 As shown, an embodiment of this utility model provides a cleaning device, including a driving component 1, a mounting base 2, and a cleaning assembly 3. The mounting base 2 is connected to the output end of the driving component 1. One end of the cleaning assembly 3 is mounted on the mounting base 2. The driving component 1 can drive the mounting base 2 to reciprocate along a first direction, and move the cleaning assembly 3 on the mounting base 2 together, so that the other end of the cleaning assembly 3 can extend into or retract from the chuck on the spindle of the PCB processing equipment. The first direction a is... Figure 1 The vertical direction in the middle.

[0039] The cleaning component 3 can be connected to an external pumping device. During the cleaning process, the other end of the cleaning component 3 is inserted into the chuck by the drive component 1, and the cleaning component 3 sprays cleaning fluid into the chuck. The process of the cleaning component 3 entering and exiting the chuck removes dust from the chuck, thus achieving cleaning of the chuck by the cleaning component 3. After cleaning, the drive component 1 drives the cleaning component 3 back to its original position, and the cleaning component 3 disengages from the chuck. The drive component 1 is a cylinder, but in other embodiments, a motor or other components can also be used.

[0040] The cleaning assembly 3 includes a connecting rod 31, a cleaning head 32, and at least one locking element 33. The mounting base 2 is provided with a fixing hole 231. One end of the connecting rod 31 is detachably connected to the fixing hole 231, and the other end of the connecting rod 31 is connected to the cleaning head 32.

[0041] For different sizes of the chuck, different lengths or shapes of the connecting rod 31 and the cleaning head 32 can be required. Through the detachable connection of the connecting rod 31 in the fixing hole 231, different types of connecting rods 31 can be used with the same mounting seat 2, so that the appropriate combination of the connecting rod 31 and the cleaning head 32 can be selected according to different cleaning needs, improving the versatility and adaptability of the cleaning assembly 3.

[0042] The locking piece 33 can fix the cleaning head 32 on the connecting rod 31, and through the locking piece 33, the cleaning head 32 is detachably connected to the connecting rod 31. When the cleaning head 32 needs to be replaced due to serious wear, the locking piece 33 is only loosened, the old cleaning head 32 is removed from the connecting rod 31, and then the new cleaning head 32 is fixed on the connecting rod 31 through the locking piece 33.

[0043] In this embodiment, through the detachable connection of one end of the connecting rod 31 with the fixing hole 231 and the detachable connection of the cleaning head 32 with the connecting rod 31, when the cleaning head 32 or the connecting rod 31 is worn or clogged, etc. affecting the cleaning effect, the entire cleaning device does not need to be disassembled as in the traditional way, but only the cleaning head 32 or the connecting rod 31 that needs to be replaced needs to be disassembled and replaced, which simplifies the replacement or maintenance process of the cleaning head 32 and the connecting rod 31, reduces the downtime caused by maintenance, and speeds up the production progress. In addition, the above detachable connection method can also reduce unnecessary parts wear and tear and reduce production costs.

[0044] In an embodiment, one end of the connecting rod 31 is provided with external threads, and the fixing hole 231 is provided with internal threads matched with the external threads. The one end of the connecting rod 31 is threadedly connected in the fixing hole 231, facilitating the installation and disassembly of the connecting rod 31.

[0045] In an embodiment, as shown in Figure 2 The cleaning head 32 includes a brush 321 and a brush rod 322, and the connecting rod 31 is provided with a first liquid spraying channel 311 and at least one connecting hole 3141. The first liquid spraying channel 311 penetrates the connecting rod 31 along the axial direction of the connecting rod 31 and is in communication with the fixing hole 231. The fixing hole 231 can be connected to external pumping equipment to enable the cleaning liquid to be sprayed from the first liquid spraying channel 311. The cleaning liquid is sprayed to the contact part of the brush 321 and the chuck, the cleaning liquid can soften the dirt, and the brush 321 can more easily remove the dirt, enhancing the cleaning effect.

[0046] The brush rod 322 is arranged in the first liquid channel 311, the brush 321 is connected to one end of the brush rod 322 and located at the end of the connecting rod 31 away from the mounting base 2, and the brush 321 can extend into or out of the chuck during cleaning. The brush 321 is used to clean or remove dirt, residues and the like on the chuck. The cleaning liquid can enter the first liquid channel 311 from the fixing hole 231 of the mounting base 2, and then the cleaning liquid is sprayed along the brush 321 from the end of the first liquid channel 311 in the axial direction. The brush 321 can be fully supplied with cleaning liquid during the entire cleaning process, and the cleaning liquid can fully soak the brush 321, thereby achieving good cleaning effect.

[0047] The material and hardness of the brush 321 are selected according to the specific application requirements to ensure that the cleaning effect is best and the workpiece is not damaged.

[0048] Each locking piece 33 is installed in the corresponding connecting hole 3141 and can abut against the brush rod 322. By abutting the brush rod 322 with the locking piece 33, the brush rod 322 can be prevented from shaking or moving in the first liquid channel 311, and the brush 321 can always be kept in the correct position for cleaning. The brush rod 322 and the first liquid channel 311 are in clearance fit, and after the locking piece 33 abuts against the brush rod 322, there is still a gap between the brush rod 322 and the first liquid channel 311 for the cleaning liquid to flow through. The cleaning liquid can be sprayed out through the gap.

[0049] Preferably, the locking piece 33 is a screw, and the connecting hole 3141 has an internal thread on the hole wall, and the locking piece 33 is screwed into the connecting hole 3141.

[0050] In an embodiment, as shown in Figure 2 , Figure 4 The first liquid channel 311 includes a first channel 3111 and a second channel 3112, the axial length of the first channel 3111 is less than the axial length of the second channel 3112, the first channel 3111 is connected between the fixing hole 231 and the second channel 3112, and a step is formed between the first channel 3111 and the second channel 3112. The step can limit the insertion position of the brush rod 322 in the first liquid channel 311.

[0051] In an embodiment, as shown in Figure 2 , Figure 4As shown, the cleaning assembly 3 further comprises a limiting member 314 sleeved on the outside of the connecting rod 31, a connecting hole 3141 is arranged on the limiting member 314, and the relative position of the connecting rod 31 and the fixing hole 231 can be limited through the limiting member 314. The connecting rod 31 comprises a first rod body 312 and a second rod body 313, and the limiting member 314 is located at the intersection of the first rod body 312 and the second rod body 313 in the axial direction of the connecting rod 31. The first rod body 312 is closer to the mounting seat 2 than the second rod body 313, and the first rod body 312 is provided with external threads. The first rod body 312 is screwed into the fixing hole 231. The first channel 3111 of the first liquid spraying channel 311 is located in the inside of the first rod body 312, and the second channel 3112 of the first liquid spraying channel 311 is located in the inside of the second rod body 313.

[0052] In an embodiment, in the axial direction of the connecting rod 31, the length of the first rod body 312 is less than the depth of the fixing hole 231, so that after the first rod body 312 is connected in the fixing hole 231, a certain space is left in the fixing hole 231, facilitating the cleaning liquid to enter the first liquid spraying channel 311 through the fixing hole 231.

[0053] In an embodiment, the cleaning device further comprises a leakage-proof baffle 4, which is arranged on the mounting seat 2. The inside of the leakage-proof baffle 4 has an inner cavity 44, part of one end of the cleaning assembly 3 is accommodated in the inner cavity 44 of the leakage-proof baffle 4, and the leakage-proof baffle 4 surrounds the cleaning assembly 3.

[0054] The driving member 1 can drive the mounting seat 2 to reciprocate in the first direction a, and when the cleaning assembly 3 is driven to extend into the chuck, the cleaning assembly 3 can clean the dust and other impurities in the chuck. The leakage-proof baffle 4 is used to abut between the main shaft and the mounting seat 2 when the cleaning assembly 3 cleans the chuck, so as to close the inner cavity 44 and block the cleaning liquid from splashing out of the inner cavity 44.

[0055] By surrounding the cleaning assembly 3 with the leakage-proof baffle 4, the other end of the cleaning assembly 3 is driven by the driving member 1 to extend into the chuck for cleaning. During the cleaning process, the cleaning liquid may not be controlled to fly in all directions. By surrounding a relatively closed space between the main shaft and the mounting seat 2 through the leakage-proof baffle 4, the inner cavity 44 is isolated from the outside world, and the cleaning liquid is always limited in a specific area, so as to prevent the cleaning liquid from splashing everywhere, avoid the cleaning liquid from splashing on the operator or the surrounding electrical equipment, and reduce the safety risk.

[0056] In an embodiment, as shown in FIG. 6, the cleaning assembly 3 further comprises a cleaning liquid supply device 5, which is arranged on the mounting seat 2 and is connected with the first liquid spraying channel 311.

The liquid storage groove 21 is recessed from the upper surface of the mounting base 2 to the lower surface of the mounting base 2 in the first direction a. The liquid return hole 22 is arranged on the side wall of the liquid storage groove 21. One end of the cleaning assembly 3 is located in the liquid storage groove 21, so that the overflowed cleaning liquid can flow into the liquid storage groove 21. The liquid storage groove 21 is used for collecting the cleaning liquid and discharging the cleaning liquid through the liquid return hole 22.

[0057] During the cleaning process of the collet, the cleaning liquid will inevitably flow or splash everywhere. After the splash of the cleaning liquid is blocked by the leakage baffle 4, the splash of the cleaning liquid can be effectively collected through the liquid storage groove 21, so as to avoid the random flow of the cleaning liquid to the working area, causing environmental pollution and equipment damage.

[0058] The liquid storage groove 21 communicates with the liquid return hole 22, so that the collected cleaning liquid can be quickly discharged through the liquid return hole 22, so that the cleaning liquid in the liquid storage groove 21 will not overflow, and the discharged cleaning liquid can be treated to remove impurities and dirt and then reused, which can save cost and reduce environmental pollution. The liquid return hole 22 is provided with one, two or more liquid return holes to achieve better liquid suction effect.

[0059] In an embodiment, as shown in the drawings, Figure 2 The liquid return hole 22 is provided with a liquid return connector 5.

[0060] In an embodiment, as shown in the drawings, Figure 2 The liquid storage groove 21 is provided with a connecting seat 23. The fixing hole 231 penetrates the connecting seat 23 in the first direction a. When the first rod body 312 is connected in the fixing hole 231, the limiting piece 314 abuts against the connecting seat 23, so as to play a limiting role.

[0061] In an embodiment, as shown in the drawings, Figure 1 The mounting base 2 is provided with a liquid injection hole 24 and a second liquid injection channel 25. The liquid injection hole 24 of the connecting seat 23 communicates with the liquid pumping device outside.

[0062] In the first direction a, the second liquid injection channel 25 is located below the liquid storage groove 21. One end of the second liquid injection channel 25 communicates with the liquid injection hole 24. The other end of the second liquid injection channel 25 communicates with the first liquid injection channel 311 through the fixing hole 231, so that the cleaning liquid sequentially passes through the liquid injection hole 24, the second liquid injection channel 25 and the fixing hole 231 and is sprayed from the first liquid injection channel 311 to the contact position of the brush 321 and the collet. Without additional pipeline connection or complex operation steps, only the liquid pumping device is connected with the liquid injection hole 24 of the mounting base 2, the supply of the cleaning liquid can be realized.

[0063] In an embodiment, the liquid injection hole 24 is provided with a liquid injection connector 6 connected with the liquid pumping device through a pipeline, so as to facilitate the delivery of the cleaning liquid.
