Description

Technical Field

[0001] The present invention belongs to the technical field of dispensing devices, and particularly relates to a dispensing device for sensor processing. Background Art

[0002] Sensor potting glue is used to pour epoxy potting glue into the installation cavity of the sensor circuit board to encapsulate and protect the circuit board and components. It can enhance the anti-vibration, compressive resistance, waterproof and sealing performance of capacitive sensors, fill gaps to improve the heat dissipation effect, and effectively reduce the environmental damage and corrosion of the circuit board.

[0003] In the prior art, there are two ways to pot sensor glue: First, manually hold the injection needle and insert it into the gap between the sensor body and the housing for dispensing; Second, use mechanical equipment for low-pressure potting, so that the glue is injected into the gap between the sensor body and the housing under low pressure.

[0004] However, both of the above two dispensing methods have certain defects. Since the gap between the sensor body and the housing is small, the sensor body may be in contact with the inner wall of the housing. When dispensing at this time, the glue liquid is truncated and cannot completely enter the gap between the sensor body and the inner wall of the housing; and when dispensing glue between the sensor body and the housing, if the glue liquid is dropped from the upper gap, a part of the air will be blocked in the gap between the sensor body and the housing, so that it cannot be discharged, resulting in a decrease in the encapsulation effect between the sensor body and the housing, thereby reducing the waterproof, anti-vibration and heat dissipation effects of the sensor. Summary of the Invention

[0005] The purpose of the present invention is to provide a dispensing device for sensor processing with a simple structure and reasonable design in order to solve the above problems.

[0006] The present invention realizes the above purpose through the following technical solutions:

[0007] A dispensing device for sensor processing includes a dispensing machine. A workbench for placing sensors is provided on the upper surface of the dispensing machine. A dispensing device is provided above the dispensing machine. The dispensing device includes a fixed seat as a support. A collar is fixedly welded on the fixed seat. A rotating ring is rotatably arranged in the collar. A stainless steel dispensing cylinder is fixedly arranged in the middle of the rotating ring. A glue injection pipe is arranged at the upper end of the stainless steel dispensing cylinder. A dispensing needle tube is arranged at the lower end of the stainless steel dispensing cylinder. The inside of the stainless steel dispensing cylinder is communicated with the dispensing needle tube. There are multiple dispensing needle tubes, and the multiple dispensing needle tubes are arranged in a circular array along the lower end surface of the stainless steel dispensing cylinder. An outlet hole is arranged on one side of the dispensing needle tube, and multiple outlet holes are arranged along the height direction of the dispensing needle tube. A cotton layer is fixedly arranged on the outer circle on the other side of the dispensing needle tube.

[0008] As a further optimization solution of the present invention, a fourth motor is provided on one side of the fixed seat. A driving gear is fixedly arranged on the rotating shaft at the lower end of the fourth motor. A driven gear is fixedly arranged on the outer circumference at the lower end of the stainless steel dispensing cylinder. The driven gear is coaxial with the stainless steel dispensing cylinder, and the driven gear meshes with the driving gear.

[0009] As a further optimization solution of the present invention, a magnetic plate is adsorbed and fixed on the lower surface of the stainless steel dispensing cylinder. A plurality of round holes for the dispensing needle tube to pass through are arranged on the magnetic plate.

[0010] As a further optimization solution of the present invention, the sensor includes a sensor body and a housing. The sensor body is installed inside the housing. A dispensing gap is formed between the inner circumference of the housing and the outer circumference of the sensor body. The dispensing gap is annular, the upper end of the dispensing gap is open, and the dispensing gap corresponds to the dispensing needle tube.

[0011] As a further optimization solution of the present invention, slide rails, a cross beam and a vertical beam are arranged on the dispensing machine. There are two slide rails, and both slide rails are fixedly connected to the upper surface of the dispensing machine by screws. Sliders are slidably arranged on both slide rails. A third wire block is fixedly arranged at the lower end of the slider. A third motor is fixedly arranged at one end of the slide rail. A third lead screw is fixedly connected to the rotating shaft of the third motor. The third lead screw cooperates with the third wire block. The two sliders are respectively fixedly connected to both ends of the cross beam.

[0012] As a further optimization solution of the present invention, a first motor is fixedly arranged at one end of the cross beam. A first lead screw is fixedly arranged on the rotating shaft of the first motor. The vertical beam is slidably arranged on the cross beam. A first wire block is fixedly arranged on the surface of the vertical beam close to the cross beam. The first lead screw cooperates with the first wire block.

[0013] As a further optimization solution of the present invention, a protective housing is fixedly arranged at the upper end of the vertical beam. A second motor is installed in the protective housing. A second lead screw is fixedly connected to the rotating shaft at the lower end of the second motor. A second wire block is connected in cooperation with the second lead screw. An installation plate is slidably arranged on the surface of the vertical beam. The second wire block is fixedly welded on the installation plate.

[0014] As a further optimization solution of the present invention, a third lead screw is fixedly connected to the installation plate. The fixed seat and the fourth motor are both fixedly installed on the surface of the third lead screw.

[0015] As a further optimization solution of the present invention, a box body is fixedly installed on one side at the upper end of the protective housing. Glue is stored in the box body. Inlet and outlet pipes are arranged on both sides of the box body. One inlet and outlet pipe is connected to the injection pipe through a hose. The injection pipe is communicated with the inside of the stainless steel dispensing cylinder.

[0016] As a further optimization solution of the present invention, a protective cover is fixedly installed above the dispensing machine.

[0017] The beneficial effects of the present invention are as follows: the stainless steel dispensing cylinder and the fixing seat of the present invention are lowered as a whole to insert the dispensing needle tube into the dispensing gap. When the fourth motor is started, the fourth motor drives the driving gear to rotate through the rotating shaft, and the driving gear is meshed with the driven gear to rotate the stainless steel dispensing cylinder. During the rotation of the stainless steel dispensing cylinder, multiple dispensing needle tubes are driven to rotate in the dispensing gap. Glue is injected from the glue injection pipeline, and the glue is injected into the dispensing gap through the stainless steel dispensing cylinder, the dispensing needle tube and the glue outlet hole in turn. Since multiple glue outlet holes are arranged along the height direction of the dispensing needle tube, the glue is evenly injected into the dispensing gap, and as the dispensing needle tube moves in the dispensing gap, the glue gradually fills the dispensing gap. When the dispensing needle tube moves, it serves the purpose of correcting the sensor body to the center of the shell, so that the width of the dispensing gap remains uniform, and it is not easy to cause the outer ring of the sensor body to fit with the inner ring of the shell so that the glue cannot pass through;

[0018] Using this method for dispensing glue can evenly fill the glue dispensing gap, which increases the dispensing efficiency.

[0019] A cotton layer is fixedly arranged at the outer ring of the other side of the dispensing needle tube. When the dispensing needle tube rotates in the dispensing gap, it rotates toward the side of the dispensing needle tube where the cotton layer is arranged, so that the dispensing needle tube can wipe off dust and impurities on the inner wall of the dispensing gap through the cotton layer during the movement in the dispensing gap. The dust and impurities are adsorbed on the surface of the cotton layer and taken out, thereby achieving the purpose of cleaning the inner wall of the dispensing gap before dispensing, and solving the problem that it is difficult to clean the narrow dispensing gap in the prior art;

[0020] In order to ensure the cleanliness of the cotton layer, a magnetic plate is adsorbed and fixed on the lower end surface of the stainless steel dispensing cylinder. The magnetic plate is provided with a plurality of circular holes for the dispensing needle to pass through. The magnetic plate is manually moved downward regularly to make the magnetic plate rise and fall reciprocatingly on the dispensing needle. The dust and impurities adsorbed on the cotton layer can be scraped off through the inner wall of the circular hole, thereby ensuring the cleanliness of the cotton layer. It is not easy to bring new dust and impurities into the dispensing gap during dispensing. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0034] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0035] As Figures 1 to 12As shown, in order to solve the problem that due to the small gap between the sensor body and the housing, the sensor body may be in contact with the inner wall of the housing. When dispensing glue at this time, the glue is truncated and cannot completely enter the gap between the sensor body and the inner wall of the housing; and when dispensing glue between the sensor body and the housing, if the glue is injected from the upper gap, a part of the air will be blocked in the gap between the sensor body and the housing, and thus cannot be discharged, resulting in a decrease in the encapsulation effect between the sensor body and the housing, thereby reducing the waterproofness, anti-vibration performance and heat dissipation effect of the sensor. The present invention proposes a dispensing device for sensor processing, including a dispensing machine 1. A workbench 3 for placing the sensor is provided on the upper surface of the dispensing machine 1. A dispensing device 11 is provided above the dispensing machine 1. The dispensing device 11 includes a fixed seat 21 as a support. A collar 24 is fixedly welded on the fixed seat 21. A rotating ring 25 is rotatably arranged in the collar 24. A stainless steel dispensing cylinder 23 is fixedly arranged in the middle of the rotating ring 25. A glue injection pipe 22 is provided at the upper end of the stainless steel dispensing cylinder 23. A dispensing needle tube 27 is provided at the lower end of the stainless steel dispensing cylinder 23. The inside of the stainless steel dispensing cylinder 23 is communicated with the inside of the dispensing needle tube 27. A plurality of dispensing needle tubes 27 are provided. The plurality of dispensing needle tubes 27 are arranged in a circular array along the lower end surface of the stainless steel dispensing cylinder 23. An glue outlet hole 29 is provided on one side of the dispensing needle tube 27. A plurality of glue outlet holes 29 are arranged along the height direction of the dispensing needle tube 27. The sensor includes a sensor body 34 and a housing 33. The sensor body 34 is installed inside the housing 33. A dispensing gap 35 is formed between the inner circle of the housing 33 and the outer circle of the sensor body 34. The dispensing gap 35 is annular. The upper end of the dispensing gap 35 is open. The dispensing gap 35 corresponds to the dispensing needle tube 27. A fourth motor 31 is provided on one side of the fixed seat 21. A driving gear 32 is fixedly arranged on the rotating shaft at the lower end of the fourth motor 31. A driven gear 26 is fixedly arranged on the outer circle at the lower end of the stainless steel dispensing cylinder 23. The driven gear 26 is coaxial with the stainless steel dispensing cylinder 23. The driven gear 26 meshes with the driving gear 32.

[0036] It should be noted that the teeth on the driving gear 32 and the driven gear 26 are not shown in the figure and are common existing structures, so they will not be elaborated here.

[0037] During operation, the stainless-steel dispensing cylinder 23 and the fixing base 21 descend as a whole to insert the dispensing needle tube 27 into the dispensing gap 35. When the fourth motor 31 is started, the fourth motor 31 drives the driving gear 32 to rotate through the rotating shaft. The driving gear 32 meshes with the driven gear 26, causing the stainless-steel dispensing cylinder 23 to rotate. During the rotation of the stainless-steel dispensing cylinder 23, multiple dispensing needle tubes 27 are driven to rotate in the dispensing gap 35, and glue is injected from the injection pipeline 22. The glue will pass through the stainless-steel dispensing cylinder 23, the dispensing needle tube 27, and the glue outlet holes 29 in sequence and be injected into the dispensing gap 35. Since there are multiple glue outlet holes 29 arranged along the height direction of the dispensing needle tube 27, the glue will be evenly injected into the dispensing gap 35. And as the dispensing needle tube 27 moves in the dispensing gap 35, the glue gradually fills the dispensing gap 35. When the dispensing needle tube 27 moves, it serves the purpose of correcting the sensor body 34 to the center of the housing 33, keeping the width of the dispensing gap 35 uniform and preventing the phenomenon that the outer ring of the sensor body 34 fits with the inner ring of the housing 33 and the glue cannot pass through.

[0038] Using this method for dispensing enables the glue to be evenly filled in the dispensing gap 35 and also increases the dispensing efficiency.

[0039] Furthermore, a cotton layer 30 is fixedly arranged on the outer ring of the other side of the dispensing needle tube 27. When the dispensing needle tube 27 rotates in the dispensing gap 35, it rotates towards the side where the cotton layer 30 is arranged. This enables the cotton layer 30 to wipe off the dust and impurities on the inner wall of the dispensing gap 35 during the movement of the dispensing needle tube 27 in the dispensing gap 35. The dust and impurities are adsorbed on the surface of the cotton layer 30 and are taken out, achieving the purpose of cleaning the inner wall of the dispensing gap 35 before dispensing and solving the problem in the prior art that it is difficult to clean the relatively narrow dispensing gap 35.

[0040] To ensure the cleanliness of the cotton layer 30, a magnetic plate 28 is adsorbed and fixed on the lower surface of the stainless-steel dispensing cylinder 23. Multiple round holes for the dispensing needle tube 27 to pass through are provided on the magnetic plate 28. Manually operate the magnetic plate 28 to move downward regularly, causing the magnetic plate 28 to reciprocate up and down on the dispensing needle tube 27. The dust and impurities adsorbed on the cotton layer 30 can be scraped off through the inner wall of the round holes, ensuring the cleanliness of the cotton layer 30 and preventing new dust and impurities from being brought into the dispensing gap 35 during dispensing.

[0041] During the process of dispensing glue to the sensors, the sensors are arranged in a matrix on the upper surface of the workbench 3, and a batch of sensors are processed by dispensing glue, with relatively high dispensing efficiency. In order to achieve dispensing glue to the sensors arranged in a matrix, the dispensing syringe 27 needs to move in the length, width, and height directions above the workbench 3. Therefore, slide rails 4, a cross beam 5, and a vertical beam 6 are provided on the dispensing machine 1. There are two slide rails 4, and both of the two slide rails 4 are fixedly connected to the upper surface of the dispensing machine 1 by screws. Sliders 8 are slidably arranged on both of the two slide rails 4. A third wire block 36 is fixedly arranged at the lower end of the slider 8. A third motor 20 is fixedly arranged at one end of the slide rail 4. A third lead screw 19 is fixedly connected to the rotating shaft of the third motor 20. The third lead screw 19 cooperates with the third wire block 36. The two sliders 8 are respectively fixedly connected to both ends of the cross beam 5. When the third motor 20 is started, it can drive the third lead screw 19 to rotate. When the third lead screw 19 rotates, it drives the third wire block 36 to move along the length direction of the slide rail 4. When the slide rail 4 moves, the slider 8 and the cross beam 5 synchronously move along the length direction of the slide rail 4.

[0042] A first motor 12 is fixedly arranged at one end of the cross beam 5. A first lead screw 18 is fixedly arranged on the rotating shaft of the first motor 12. The vertical beam 6 is slidably arranged on the cross beam 5. A first wire block 17 is fixedly arranged on the surface of the vertical beam 6 close to the cross beam 5. The first lead screw 18 cooperates with the first wire block 17. When the first motor 12 is started, it drives the first lead screw 18 to rotate. When the first lead screw 18 rotates, it can drive the first wire block 17 to move on the cross beam 5. When the first wire block 17 moves, the vertical beam 6 moves along the length direction of the cross beam 5.

[0043] A protective housing 7 is fixedly arranged at the upper end of the vertical beam 6. A second motor 13 is installed in the protective housing 7. A second lead screw 14 is fixedly connected to the rotating shaft at the lower end of the second motor 13. A second wire block 15 is connected in cooperation with the second lead screw 14. A mounting plate 16 is slidably arranged on the surface of the vertical beam 6. The second wire block 15 is fixedly welded to the mounting plate 16. When the second motor 13 is started, it drives the second lead screw 14 to rotate. When the second lead screw 14 rotates, it drives the second wire block 15 to move along the height direction of the vertical beam 6. When the second wire block 15 moves, the mounting plate 16 synchronously moves along the height direction of the vertical beam 6.

[0044] A third lead screw 19 is fixedly connected to the mounting plate 16. A fixed seat 21 and a fourth motor 31 are both fixedly installed on the surface of the third lead screw 19. When the third lead screw 19 synchronously moves in space with the vertical beam 6, the stainless steel dispensing cylinder 23 and the dispensing syringe 27 can synchronously move with the third lead screw 19, realizing the dispensing operation.

[0045] A box body 9 is fixedly installed on one side of the upper end of the protection housing 7. The box body 9 stores glue. Both sides of the box body 9 are provided with inlet and outlet pipes 10. One inlet and outlet pipe 10 is connected to the glue injection pipe 22 through a hose, and the other inlet and outlet pipe 10 is connected to the glue supply mechanism. The glue injection pipe 22 is internally communicated with the stainless steel dispensing cylinder 23. After the glue is supplied to the box body 9 by the glue supply mechanism, it is then sequentially transported to the stainless steel dispensing cylinder 23 through the inlet and outlet pipe 10, the hose and the glue injection pipe 22.

[0046] It should be noted that the glue supply mechanism is a storage tank and a material pump. The storage tank stores glue, and the material pump transports the glue in the storage tank to the box body 9.

[0047] A protective cover 2 is fixedly installed above the dispensing machine 1, which has good protection and has a certain dust-proof effect.

[0048] It should also be noted that the workbench 3 is made of a magnetic plate and can be used to adsorb and fix the sensor. The induction unit in the sensor can be adsorbed by a magnetic object to achieve the purpose of adsorption and positioning. In actual use, the workbench 3 can also use a negative pressure suction plate or other structures for the sensor to be stably placed, which is a common existing fixing technology and will not be elaborated here.

[0049] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
