Description

Technical Field

[0001] This utility model relates to the field of sensor manufacturing technology, and in particular to a sensor cleaning device and sensor processing equipment. Background Technology

[0002] In sensor manufacturing, pad treatment is a critical process affecting sensor performance and subsequent assembly quality. It involves multiple steps, including material loading, polishing, cleaning, and soldering. In existing sensor processing equipment, each step is independent and operated manually or semi-automatically. For example, sensor pads need to be cleaned after polishing to avoid affecting subsequent soldering, and they also need to be cleaned again after soldering to ensure a clean surface and prevent poor contact during sensor use. However, current sensor cleaning methods commonly used in the industry suffer from two main problems: 1. Using fixed brushes or wiping blocks for cleaning is not flexible in terms of adjusting the cleaning position. It has poor compatibility with different sensor specifications, and the cleaning parts are prone to wear, requiring frequent shutdowns for replacement, which affects production efficiency.

[0003] 2. Although some cleaning devices can be moved simply, they can only adjust the cleaning position in one direction, making it difficult to fully cover the solder pad area and leaving cleaning dead spots. At the same time, the cleaning media (such as cleaning cloths) are mostly fixed and replaceable, and cannot be put away and updated in real time. Used cleaning media can easily cause secondary pollution, further reducing the cleaning effect.

[0004] Therefore, there is an urgent need for a sensor cleaning device and sensor processing equipment to solve the above problems. Utility Model Content

The feeding conveyor line 200 is arranged along the length of the frame 100; The feeding device 300 is connected to the beginning of the feeding conveyor line 200 and is used to provide sensors to the feeding conveyor line 200; The grinding device 400 is connected to the rear end of the feeding device 300 and is used to grind the pads of the sensor. The first cleaning device 500a is connected to the rear end of the polishing device 400 and is used to clean the polished pads on the sensor. The soldering device 600 is connected to the rear end of the first cleaning device 500a and is used to apply solder to the pads of the sensor. The second cleaning device 500b is connected to the rear end of the soldering device 600 and is used to clean the solder pads on the sensor after soldering. The unloading device 700 is connected to the rear end of the second cleaning device 500b and is used to remove the sensor from the feeding conveyor line 200.

[0018] The working principle of the automatic sensor processing equipment in this invention is as follows: ①Reference Figure 1 and Figure 2 Preferably, the feeding device 300 includes a first motion component 310, a floating seat 320, a clamping component 330, a detection component 340, and a plurality of feeding bins 350. The feeding bins 350 are evenly distributed on both sides of the feeding conveyor line 200 and are used to store stacked fixtures 800. Each fixture 800 carries a plurality of sensors arranged at intervals along its length. The floating seat 320 is mounted on the first motion component 310 and can slide up and down relative to the first motion component 310. The floating seat 320 is provided with a supporting part. 321 is used to adjust the fixture 800 to be parallel to the horizontal plane when it comes into contact with the fixture 800; the clamping component 330 is installed on the floating seat 320 for clamping the fixture 800; the detection component 340 is installed on the floating seat 320 for detecting the distance between the fixture 800 located at the uppermost end in the feeding bin 350; the clamping component 330 can clamp the fixture 800 located at the uppermost end when the detection component 340 detects that the distance has reached the threshold, and transfer it to the feeding conveyor line 200 through the first motion component 310.

[0019] Specifically, there are six feeding bins 350, three of which are located on the left side of the feeding conveyor line 200, and the other three on the right side. The feeding conveyor line 200 transports the fixture 800 along the Y-axis. Furthermore, the first motion component 310 is preferably configured as an XZ-axis motion module, capable of driving the floating seat 320, the clamping component 330, and the detection component 340 to move in the X and Z-axis directions. For example, in one stroke, the XZ-axis motion module drives the floating seat 320, the clamping component 330, and the detection component 340 to move above the feeding bins 350. The detection component 340 detects the distance between itself and the uppermost fixture 800 within the feeding bins 350 in real time. Simultaneously, the detection component 340 and the first motion component 310 drive the floating seat 320, the clamping component 330, and the first motion component 310 to move the first motion component 310. Component 330 and detection component 340 gradually approach the fixture 800 until the distance reaches the threshold. At this time, the supporting part 321 on the floating seat 320 abuts against the fixture 800. Since the floating seat 320 is slidably connected to the first motion component 310, it will push the fixture 800 to be parallel to the horizontal plane. Finally, the clamping component 330 is activated to clamp the fixture 800. Finally, the first motion component 310 drives the fixture 800 to be close to the feeding conveyor line 200. Then, the clamping component 330 is released, allowing the fixture 800 to be placed on the feeding conveyor line 200 and conveyed to the next process by the feeding conveyor line 200. This cycle continues. When the fixture 800 in one or more loading bins 350 is emptied, the fixture 800 is manually replenished by the operator. Of course, in some embodiments, it can also be automatically replenished by an automated device, which will not be described in detail here.

[0020] Reference Figure 1 and Figure 2 In some embodiments, a slide block 361 is provided on the floating seat 320, and a slide groove 362 is provided on the first motion component 310. The slide block 361 is slidably disposed in the slide groove. In a further embodiment, the lower end of the slide groove 362 is at least partially closed to restrict the slide block 361 from disengaging from the slide groove 362. Specifically, since the floating seat 320 is connected to the first motion component 310 by gravity, when the abutment part 321 abuts against the uppermost fixture 800, the floating seat 320 will be pushed back a short distance. That is, after waiting for a preset time, the fixture 800 is clamped in the clamping component 330. This not only adjusts the fixture 800 from an inclined state to a horizontal state, but also avoids damage to the fixture 800 and / or the sensor caused by the floating seat 320 pushing against the fixture 800, so that the clamping component 330 can successfully clamp the fixture 800.

[0021] Preferably, a fixture 800 has 8 slots, which can simultaneously support 8 sensors for processing, as shown in the reference. Figure 1 and Figure 2In some embodiments, two clamping components 330 are provided and arranged at intervals along the length of the fixture 800, respectively for clamping the front end and rear end of the fixture 800; preferably, the clamping components 330 are configured as gripper cylinders; this configuration can improve the stability of the clamping components 330 in clamping the fixture 800, and avoid the fixture 800 from shaking during the transfer process, which could cause the sensor to fall off or the fixture 800 to fail to be accurately placed on the feeding conveyor line 200.

[0022] ②Reference Figure 1 and Figure 3 In some embodiments, the polishing device 400 includes a second motion component 410, a plurality of polishing components 420, and a plurality of abrasive boxes 430; the polishing components 420 are mounted on the second motion component 410; the abrasive boxes 430 are used to hold liquid abrasive; the second motion component 410 can drive the polishing components 420 to pick up liquid abrasive from the abrasive boxes 430 and drive the polishing components 420 to polish the pads of the sensor.

[0023] In the embodiment where the fixture 800 simultaneously carries eight sensors, the grinding components 420 are configured in four groups, enabling simultaneous grinding of four sensors. Grinding of all eight sensors can be completed in two passes, significantly improving production efficiency. Specifically, the four grinding components 420 are mounted on the second motion component 410 and spaced apart along the Y-axis. Each grinding component 420 includes a first motor 421 and a grinding head 422, with the grinding head 422 mounted at the output end of the first motor 421. Preferably, the second motion component 410 is configured as a first XYZ axis motion module. In one stroke, the first XYZ axis motion module first drives the grinding component 420 to approach the abrasive box 430 and pick up liquid abrasive, improving the grinding efficiency of the grinding component 420. The grinding effect is achieved by first XYZ axis motion module driving grinding component 420 to approach the sensor on fixture 800 until the grinding of the first group of 4 sensors is completed. Preferably, the sensors 1, 3, 5, and 7 along the length of fixture 800 are grouped together, and the sensors 2, 4, 6, and 8 are grouped together. That is, during the first grinding, sensors 1, 3, 5, and 7 are ground first. After grinding, the first XYZ axis motion module drives the 4 grinding components 420 to move a certain distance along the Y-axis until the 4 grinding components 420 are opposite sensors 2, 4, 6, and 8 respectively, and then the sensors 2, 4, 6, and 8 are ground. This reduces the movement distance of the first XYZ axis motion module, which helps to further improve grinding efficiency.

[0024] ③Reference Figure 1 , Figures 4-5In some embodiments, the first cleaning device 500a includes a bracket 510a, a first movable plate 520a, a second movable plate 530a, an unwind reel 540a, a take-up reel 550a, a second motor 560a, a first drive assembly 570a, and a second drive assembly 580a; the first movable plate 520a is slidably disposed on the bracket 510a; the second movable plate 530a is slidably disposed on the first movable plate 520a; the unwind reel 540a and the take-up reel 550a are rotatably disposed on the first movable plate 520a; the second motor 560a is connected to the take-up reel 550a and is used for... The drive reel 550a rotates; the first drive assembly 570a is mounted on the bracket 510a and connected to the first movable plate 520a, and is used to drive the first movable plate 520a to move relative to the bracket 510a in the Z-axis direction; the second drive assembly 580a is mounted on the first movable plate 520a and connected to the second movable plate 530a, and is used to drive the second movable plate 530a to move relative to the first movable plate 520a in the X-axis direction; one end of the cleaning cloth is connected to the unwind reel 540a, and the other end is wrapped around the lower end of the second movable plate 530a and connected to the reel 550a.

[0025] Specifically, in one stroke, the second motor 560a first drives the take-up reel 550a to rotate until the clean cleaning cloth is aligned with the fixture 800. Then, the first drive assembly 570a drives the second movable plate 530a, the unwind reel 540a, the take-up reel 550a, the second motor 560a, and the second drive assembly 580a to move downward along the Z-axis until they are in contact with the sensor on the fixture 800. Then, the second drive assembly 580a drives the second movable plate 530a, the unwind reel 540a, the take-up reel 550a, and the second motor 560a to reciprocate along the X-axis, thereby cleaning the liquid abrasive and grinding debris remaining on the pads. After cleaning, the first drive assembly 570a drives the second movable plate 530a, the unwind reel 540a, the take-up reel 550a, and the second motor 560a to reciprocate. The two movable plates 530a, unwind reel 540a, rewind reel 550a, second motor 560a, and second drive assembly 580a move upward along the Z-axis until they separate from the fixture 800. Finally, the second motor 560a drives the rewind reel 550a to rotate, thereby partially winding up the cleaning cloth. This results in the used part of the cleaning cloth being wound up, while the clean part moves from the unwind reel 540a to be opposite the fixture 800, and this cycle repeats. Preferably, the first drive assembly 570a and the second drive assembly 580a are both cylinders. During cleaning, the first drive assembly 570a remains in an extended state, ensuring that the cleaning cloth is always in contact with the fixture 800, and then the second drive assembly 580a drives the cleaning cloth to wipe back and forth.

[0026] Reference Figure 1 , Figures 4-5In some embodiments, the first movable plate 520a is provided with a first tensioning component 591a opposite to the unwinding reel 540a and a second tensioning component 592a opposite to the take-up reel 550a. One end of the cleaning cloth is connected to the unwinding reel 540a, and the other end is sequentially wound around the first tensioning component 591a, the lower end of the second movable plate 530a, and the second tensioning component 592a and connected to the take-up reel 550a. This arrangement can keep the cleaning cloth in a taut state at all times, thereby keeping the cleaning cloth in good contact with the fixture 800 (sensor), which is beneficial to improving the cleaning effect and the unwinding and take-up effect of the cleaning cloth.

[0027] ④Reference Figure 1 and Figure 6 In some embodiments, the soldering device 600 includes a third motion component 610, a soldering iron 620, a solder inlet component 630, a solder guide tube 640, and a solder paste inlet component 650; the soldering iron 620 is mounted on the third motion component 610; the solder inlet component 630 is mounted on the third motion component 610 and is used to provide solder wire; one end of the solder guide tube 640 is connected to the solder inlet component 630 and the other end extends to the soldering iron 620; the solder paste inlet component 650 is connected to the solder guide tube 640 and is used to provide solder paste so that the solder wire in the solder guide tube 640 is immersed in the solder paste.

[0028] Specifically, the solder wire is provided by the solder inlet component 630, which enters from one end of the solder guide tube 640 and exits from the other end. The solder paste inlet component 650 provides solder paste (flux) into the solder guide tube 640, so that the solder paste completely submerges the solder wire within the solder guide tube 640. The other end of the solder guide tube 640 extends to the soldering iron 620, where it is heated and melted, adhering to the polished solder pads. Preferably, the soldering iron 620, solder inlet component 630, solder guide tube 640, and solder paste inlet component 650 are configured as two sets, enabling simultaneous soldering of two sensors. For example, in an embodiment where the fixture 800 simultaneously carries eight sensors, the third motion component 610 drives the two sets of soldering irons 620 to first solder sensors 1 and 5, and then the third motion component 610 drives the two sets of soldering irons 620 along the Y-axis. The two sets of soldering irons 620 move along the Y-axis until they align with sensors 2 and 6 and are tinned. Then, the third motion component 610 drives the two sets of soldering irons 620 to move along the Y-axis until they align with sensors 3 and 7 and are tinned. Then, the third motion component 610 drives the two sets of soldering irons 620 to move along the Y-axis until they align with sensors 4 and 8 and are tinned. Finally, the third motion component 610 drives the two sets of soldering irons 620 to reset. It should be noted that four tinning devices 600 are set and arranged at intervals along the conveying direction of the feeding conveyor line 200. Since the tinning process takes a long time, while the polishing and cleaning processes take less time, setting multiple tinning devices 600 to adapt to the polishing and cleaning processes can avoid affecting the overall production efficiency of the processing equipment.

[0029] Furthermore, the second motion component 410 is configured as a second XYZ axis motion module. A sensor cleaning device also includes a solder blowing component and a solder bath 660. The solder blowing component is mounted on the third motion component 610 and faces the soldering iron 620. The solder bath 660 is mounted on the frame 100 with its open end facing the soldering iron 620. The solder blowing component can blow residual solder on the soldering iron 620 into the solder bath 660 when the third motion component 610 drives the soldering iron 620 close to the solder bath 660. Specifically, the second motion component 410 first... The soldering iron 620 is moved along the Z-axis to approach the sensor and apply solder. Then, the soldering iron 620 is moved along the Z-axis and X-axis to approach the solder bath 660. The solder blowing component blows the residual solder and solder paste on the soldering iron 620 into the solder bath 660. Then, it retracts along the Z-axis and X-axis and moves along the Y-axis to the next sensor, until all sensors on the fixture 800 are soldered. After each sensor is soldered, the residual solder and solder paste on the soldering iron 620 is cleaned to ensure the quality of soldering the next sensor.

[0030] Furthermore, the sensor has three pads, corresponding to two signal terminals and one ground terminal. By setting the cross-sectional outline of the soldering iron 620 in the XY plane to a rectangle, and cooperating with the movement of the second XYZ axis motion module in the Y-axis direction, the soldering of the three pads can be completed simultaneously in the form of "drag soldering", which greatly improves the soldering efficiency.

[0031] ⑤Reference Figure 1 and Figure 7 In some embodiments, a Y-axis motion module 810 and a vision inspection device 820 mounted on the Y-axis motion module 810 are provided between the second cleaning device 500b and the unloading device 700. Specifically, the vision inspection device 820 can move along the Y-axis under the drive of the Y-axis motion module 810, thereby taking pictures and inspecting all sensors on the fixture 800 (arranged along the Y-axis in the length direction) one by one. Furthermore, a defective product area 900 is provided on the frame 100. When the vision inspection device 820 detects that the processing effect of a certain sensor is unqualified, the sensor is transferred to the defective product area 900 for reprocessing. It should be noted that the second cleaning device 500b can adopt the same structure as the first cleaning device 500a, which will not be described in detail here, nor should it be considered as a limitation of this utility model.

[0032] Furthermore, refer to Figure 8The unloading device 700 includes a fourth motion component 710 and a fifth motion component 720, as well as multiple first unloading bins 730 and multiple second unloading bins 740. The defective product area 900 is located on the left side of the end of the feeding conveyor line 200. The multiple first unloading bins 730 are located on the right side of the end of the feeding conveyor line 200 and opposite to the fourth motion component 710. The multiple second unloading bins 740 are opposite to the fifth motion component 720. The fourth motion component 710 includes a second XZ-axis motion module and a second clamping component, and can transfer defective sensors to the defective product area 900. The fifth motion component 720 includes a third XZ-axis motion module and a third clamping component, and can transfer qualified sensors to the second unloading bins 740. Furthermore, when the transfer efficiency of the fifth motion component 720 cannot keep up, the fourth motion component 710 can transfer qualified sensors to the first unloading bins 730, thereby matching the production efficiency of the entire processing equipment.

[0033] ⑥ In some embodiments, a first spraying device is provided between the polishing device 400 and the first cleaning device 500a for spraying cleaning agent onto the sensor pads; this can improve the cleaning effect on the pads after polishing and avoid affecting the subsequent soldering effect; in a further embodiment, a second spraying device is provided between the soldering device 600 and the second cleaning device 500b for spraying cleaning agent onto the sensor pads, which can improve the cleaning effect on the pads after soldering and avoid residual molten solder or solder paste on the pads.

[0034] The advantages of this invention are: the dual-axis coordinated adjustment allows the cleaning cloth to fully cover the solder pads, completely eliminating cleaning dead corners and improving cleaning accuracy; and after each cleaning, the used cleaning cloth is promptly rolled up, and a new cleaning cloth is simultaneously released from the unwinding reel, ensuring that clean media is used for each cleaning, effectively avoiding secondary pollution and ensuring stable cleaning results.
