Description

Technical Field

[0001] This invention relates to the field of automotive rain sensor assembly technology, specifically to an assembly equipment and method for processing automotive rain sensors. Background Technology

[0002] The rain sensor is an important component of modern automotive advanced driver assistance systems. It is usually installed on the windshield near the rearview mirror. The sensor itself consists of a base, a control board, and a top cover. The control board has a sunlight receiving module, a temperature and humidity module, a rain LED emitting module, a rain receiving module, and a light receiving module installed on its surface. By cooperating with each other, the modules emit infrared light and receive the intensity of light reflected from the windshield to detect the presence of raindrops and the amount of rain, thereby determining the amount of rainfall.

[0003] However, existing assembly equipment for processing automotive rain sensors still has the following problems:

[0004] 1. The existing assembly line has scattered processes, multiple equipment combinations occupy a large area, and it relies heavily on manual handling and turnover, which is inefficient and prone to errors.

[0005] 2. In the existing clamping method, during the assembly process, due to the thinness of the control board and the presence of multiple precision modules on its surface, the rigid contact of the mechanical grippers can cause deformation of the module pins or microcracks in the circuit board substrate. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an assembly equipment and method for processing automotive rain sensors. The main purpose is to solve the problem that the rigid contact of mechanical grippers can cause deformation of module pins or microcracks in the circuit board substrate due to the thin thickness of the control board and the presence of multiple precision modules on its surface.

The bottom end of each first sliding rod is fixedly connected to the same rubber pressure block, and the rubber pressure block is located between the two belt groups.

[0012] As a further embodiment of the present invention, the rubber pad conveying assembly includes a rubber pad conveying mechanism disposed on one side of the workbench and a rubber pad two-axis moving platform mounted on the top surface of the workbench. A rubber pad finger cylinder is disposed on one side of the rubber pad two-axis moving platform.

A rubber pad limiting group is fixedly connected to the bottom surface of each of the third connecting plates, and each rubber pad limiting group consists of two symmetrically arranged rubber pad limiting blocks. A slot is opened on the adjacent side of the two opposite rubber pad limiting blocks. The rubber pad is inserted into the slot. A plurality of rubber pad support frames are fixedly connected to the surface of the rubber pad conveying mechanism along the axis. A rubber pad support rod is fixedly connected to the four corners of the rubber pad support frame. Each rubber pad support rod is inserted into the corresponding rubber pad positioning hole.

[0014] As a further embodiment of the present invention, the top cover conveying assembly includes a top cover conveying mechanism disposed on one side of the workbench and a top cover two-axis moving platform mounted on the top surface of the workbench.

[0017] An assembly method for manufacturing automotive rain sensors includes the following steps:

[0018] S1: The bottom shell conveying assembly is started, which conveys the sensor bottom shell to be assembled to the designated assembly position on the turntable, waiting for subsequent assembly operations.

[0019] S2: The control board transmits the component's movement, precisely transporting the sensor control board to the position on the turntable corresponding to the bottom shell, so that it can be assembled with the bottom shell;

[0020] S3: The rubber pad conveying assembly starts working, conveying the rubber parts to the turntable. After the initial assembly of the bottom shell and control board, the auxiliary installation makes the connection of each part of the sensor tighter.

[0021] S4: The top cover conveyor assembly operates, conveying the sensor top cover to the sensor on the turntable, which has already been partially assembled, in preparation for the installation of the top cover.

[0022] S5: The sensor assembly is activated to press the sensor, which has already been integrated with the bottom shell, control board, rubber parts and top cover, to ensure that all parts are tightly joined together to form a complete sensor.

[0023] Compared with the prior art, the present invention provides an assembly equipment and method for processing automotive rain sensors, which has the following beneficial effects:

[0024] 1. This invention achieves fully automated assembly line operation from bottom shell loading, control board installation, rubber pad bonding, top cover sealing to overall pressing through the circular collaborative layout of the turntable and five major conveying components. The process is seamlessly connected, eliminating the interval time for manual handling and positioning. Compared with traditional manual or semi-automatic assembly methods, the production efficiency is increased by orders of magnitude.

[0025] 2. This invention innovatively employs a clamping solution combining a "belt-driven bottom support" and a "rubber clamping block for limiting" for precision and easily damaged components such as control panels. This design avoids bending of the panel caused by direct contact with rigid grippers, while ensuring the panel's horizontal orientation during handling and placement. Combined with the limiting posts inside the base and the limiting holes on the control panel, this significantly reduces the assembly defect rate.

[0026] 3. By employing multi-point positioning and lateral slot-type clamping, this invention ensures the stability of the flexible rubber pad during transfer. During installation, the bottom column is inserted into the positioning hole first, effectively avoiding bending, wrinkling, or displacement of the rubber pad caused by direct downward pressure, ensuring its flat coverage on the control panel, thereby guaranteeing the final sealing and cushioning effect of the product.

[0027] 4. This invention uses diffuse reflection photoelectric sensors at key workstations to monitor the status of workpieces in real time. When a workpiece is removed, the sensor immediately triggers a signal to drive the corresponding conveyor mechanism to replenish the material. This intelligent linkage mechanism eliminates production line interruptions caused by material shortages.

[0028] 5. This invention sets up an independent sensor transfer and pressing station, which is then moved to a dedicated pressing mechanism by a six-axis robotic arm. This ensures that the buckles or structural components of the bottom shell and top cover are tightly joined, eliminating gaps. The rubber pad in the middle is evenly stressed during this process, which not only enhances the stability of the overall structure but also acts as a buffer layer to protect the internal control board, thus improving the mechanical strength of the final product.

[0029] 6. This invention constructs a precise positioning system throughout the entire process by using the first bottom shell positioning frame, the control board positioning frame, and the second bottom shell positioning frame on the turntable. Each component is precisely constrained in a preset position during loading, unloading, and assembly. Combined with a high-precision two-axis moving platform and robotic arm, the cumulative error is effectively controlled to an extremely low level, ensuring the repeatability of positioning accuracy in each process, thereby guaranteeing the consistency of the final product performance.

[0052] Please see Figures 1-13 As shown, an assembly equipment for processing automotive rain sensors includes a workbench 1 and a turntable 11 mounted on the top surface of the workbench 1. The top surface of the workbench 1 is provided with a bottom shell conveying assembly 2 for transferring the bottom shell of the sensor, a control board conveying assembly 3 for transferring the sensor control board, a rubber pad conveying assembly 4 for assisting in a tighter sensor installation, a top cover conveying assembly 5 for transferring the sensor top cover, and a sensor assembly 6 for pressing the integrated sensor together. The bottom shell conveying assembly 2, the control board conveying assembly 3, the rubber pad conveying assembly 4, the top cover conveying assembly 5, and the sensor assembly 6 are all arranged in a ring around the turntable 11.

[0053] A method for assembling and using a car rain sensor:

[0054] Step 1: The bottom shell conveying assembly 2 is started, which conveys the sensor bottom shell to be assembled to the designated assembly position on the turntable 11, waiting for subsequent assembly operations.

[0055] Step 2: The control board conveying assembly 3 operates to precisely transport the sensor control board to the position on the turntable 11 corresponding to the bottom shell, so that it can be assembled with the bottom shell.

[0056] Step 3: The rubber pad conveying assembly 4 starts working, conveying the rubber parts to the turntable 11. After the initial assembly of the bottom shell and control board, the auxiliary installation makes the connection of each part of the sensor tighter.

[0057] Step 4: The top cover conveying assembly 5 operates, conveying the sensor top cover to the turntable 11 above the partially assembled sensor, in preparation for the installation of the top cover.

[0058] Step 5: The sensor assembly 6 is activated to press the sensor, which has already been integrated with the bottom shell, control board, rubber parts and top cover, to ensure that all parts are tightly joined to form a complete sensor.

[0059] To solve the technical problem of transferring the bottom shell during sensor assembly, this invention employs a bottom shell conveying assembly 2, which includes a bottom shell conveying mechanism 21 disposed on one side of the workbench 1. A two-axis moving platform 22 for the bottom shell is mounted on the top surface of the workbench 1. A bottom shell finger cylinder 23 is mounted on one side of the two-axis moving platform 22. The two grippers of the bottom shell finger cylinder 23 are respectively fixedly connected to a first clamp 24 by bolts. The side vertical cross section of the first clamp 24 is an inverted "U" shaped structure. Several first bottom shell positioning frames 26 are uniformly fixedly connected along the axis of the bottom shell conveying mechanism 21. The first bottom shell positioning frame 26 is rectangularly arranged by four columns. The bottom shell is located inside the first bottom shell positioning frame 26. Several second bottom shell positioning frames 27 are fixedly connected along the circumference of the top surface of the turntable 11. The second bottom shell positioning frames 27 have the same structure as the first bottom shell positioning frames 26, and each second bottom shell positioning frame 27 corresponds to each workstation.

[0060] When the bottom shell needs to be transferred, the bottom shell is first placed inside each first bottom shell positioning frame 26. The four columns of the first bottom shell positioning frame 26 limit the bottom shell, so that the bottom shells on the surface of the bottom shell conveying mechanism 21 are all on the same axis. Then, the lateral movement mechanism inside the bottom shell two-axis moving platform 22 is activated. The lateral movement mechanism moves the bottom shell finger cylinder 23 to a position on the same vertical axis as the first bottom shell positioning frame 26. Then, the vertical movement mechanism inside the bottom shell two-axis moving platform 22 moves the bottom shell finger cylinder 23 closer to the first bottom shell positioning frame 26 until the two first clamps 2 When the 4 are located on both sides of the bottom shell, the bottom shell finger cylinder 23 is activated, and the two grippers approach the bottom shell and clamp it. Then, the bottom shell is lifted by the horizontal and vertical moving mechanism and moved to the top of the turntable 11, perpendicular to one of the second bottom shell positioning frames 27. Then, the bottom shell is placed inside the second bottom shell positioning frame 27 by the bottom shell two-axis moving platform 22. The second bottom shell positioning frame 27 limits the bottom shell again. Then, the worktable 1 is activated, and the bottom shell is moved by the second bottom shell positioning frame 27 to align with the control board conveying assembly 3, thus achieving precise positioning and transfer of the bottom shell.

[0061] During this process, the coordinated operation of the lateral and vertical moving mechanisms ensures the stability and accuracy of the bottom shell transfer, avoiding damage or positional deviation of the bottom shell due to shaking or offset. At the same time, the shapes of the two first clamps 24 can avoid the curved surface of the bottom shell when clamping it, and can firmly clamp the bottom shell. After the bottom shell is accurately placed inside the second bottom shell positioning frame 27, the limiting function of the second bottom shell positioning frame 27 further ensures the stability of the bottom shell in subsequent processing or manufacturing, providing a strong guarantee for the smooth progress of the entire production process.

[0062] To address the technical challenge of control board transfer during sensor assembly, this invention employs a control board transfer assembly 3 comprising a control board transfer mechanism 31 positioned on one side of a workbench 1. A two-axis control board moving platform 32 is mounted on the top surface of the workbench 1. A control board finger cylinder 33 is mounted on one side of the two-axis control board moving platform 32. Two grippers of the control board finger cylinder 33 are respectively fixedly connected to second connecting plates 34 via bolts. Each second connecting plate 34 has a belt assembly 35 at its bottom end. Several control board positioning frames 36 are uniformly fixedly connected along the axis of the surface of the control board transfer mechanism 31. Each control board positioning frame 36 consists of two symmetrically arranged positioning discs, with two limiting blocks symmetrically fixedly connected to the top surface of one of the positioning discs. The control board is located on the top surface of the control board positioning frame 36, and the three probes of the control board are located on either side of the two limiting blocks.

[0063] Two first slide cylinders 37 are symmetrically fixed to both sides of the control panel finger cylinder 33 by bolts. Each first slide cylinder 37 has a first slide rod 38 slidably connected inside. The bottom end of each first slide rod 38 is fixedly connected to the same rubber pressure block 39, and the rubber pressure block 39 is located between the two belt groups 35.

[0064] When the control board needs to be placed inside the bottom shell, the control board is first placed on the top surface of each control board positioning bracket 36, and the ejector pin of the control board is oriented towards the two limit blocks. This supports the control board while also determining its orientation and limiting its position.

[0065] Then, the two-axis moving platform 32 of the control board is activated. The second connecting plate 34 is moved closer to the control board via the two-axis moving platform 32 until the two belt assemblies 35 are positioned on both sides of the control board and below its bottom surface. When the control board finger cylinder 33 approaches the control board from a vertical direction, the rubber pressure block 39 contacts the top surface of the control board. The rubber pressure block 39 is then forced to slide upwards inside the first slide cylinder 37 until the belt assembly 35 is below the bottom surface of the control board. At this point, the control board finger cylinder 33 is activated, and the two second connecting plates... 34 will drive the two belt sets 35 to move closer to each other. The two belt sets 35 will move closer to each other on the bottom surface of the control board, thereby "lifting" the control board. This avoids the clamping formed by the two sides of the control board sticking to each other in the traditional sense. The traditional clamping method may cause the control board to tilt due to its thinness. When the two belt sets 35 lift the control board, the rubber pressure block 39 will stick tightly to the top surface of the control board due to gravity. This not only limits the control board with pressure, but also keeps the control board in a horizontal state due to pressure.

[0066] When the control board is positioned vertically to the bottom shell via the two-axis moving platform 32, and the bottom surface of the belt assembly 35 is aligned with the opening of the bottom shell, the control board finger cylinder 33 will use grippers to move the two belt assemblies 35 away from each other. Due to friction, the control board will cause the pulley to roll via the belt of the third connecting plate 45, thereby reducing the friction on the control board. This prevents the placement position from shifting due to greater friction on one side when the control board is released. When the two belt assemblies 35 release their restraint on the control board, the rubber pressure block 39 will move the control board into the bottom shell due to gravity without tilting, thus achieving the placement of the control board.

[0067] When placing the control board, limit holes are provided at the positions opposite to the bottom column inside the bottom shell. When the control board is placed inside the bottom shell, the bottom column will insert into the limit holes to limit the control board.

[0068] It should be noted that the belt assembly 35 includes two symmetrically arranged pulleys and a belt fitted onto the surfaces of the two pulleys. Those skilled in the art can configure it according to actual needs, which will not be elaborated here.

[0069] To solve the technical problem of rubber pad transfer during sensor assembly, this invention employs a rubber pad conveying assembly 4, which includes a rubber pad conveying mechanism 41 disposed on one side of the workbench 1 and a rubber pad two-axis moving platform 42 mounted on the top surface of the workbench 1. A rubber pad finger cylinder 44 is disposed on one side of the rubber pad two-axis moving platform 42. The two grippers of the rubber pad finger cylinder 44 are respectively fixedly connected to a third connecting plate 45. A rubber pad limiting group is fixedly connected to the bottom surface of each third connecting plate 45, and each rubber pad limiting group consists of two symmetrically arranged rubber pad limiting blocks 46. A slot 47 is opened on the adjacent side of the two opposite rubber pad limiting blocks 46, and the rubber pad is inserted into the slot 47. Several rubber pad support frames 411 are fixedly connected to the surface of the rubber pad conveying mechanism 41 along the axis. A rubber pad support rod 43 is fixedly connected to the four corners of the rubber pad support frame 411, and each rubber pad support rod 43 is inserted into the corresponding rubber pad positioning hole.

[0070] Two second slide rods 410 are symmetrically fixedly connected to the bottom surface of each third connecting plate 45. A second slide cylinder 48 is slidably connected to the surface of each second slide rod 410. The bottom surface of each second slide cylinder 48 is parallel to the top surface of the inner wall of the slot 47. A guide plate 49 is fixedly connected to the bottom end of each second slide cylinder 48. The guide plate 49 is inclined, and the adjacent end of each guide plate 49 is higher than the bottom surface of the second slide cylinder 48.

[0071] Since the sensor is used in a vehicle, the vehicle will inevitably experience bumps while driving, which will cause the control board to shake. Therefore, a rubber pad that does not obstruct use needs to be covered on the surface of the control board. When the rubber pad needs to be installed, the rubber pad is placed on the top surface of each rubber pad support bracket 411, and the rubber pad support rod 43 is inserted into the positioning hole of the rubber pad, thereby achieving precise positioning of the rubber pad.

[0072] When the rubber pad finger cylinder 44 is moved to a position perpendicular to the rubber pad support frame 411 by the two-axis moving platform 42, and close to the rubber pad until the rubber pad in the slot 47 is parallel to the slot 47, the two sets of rubber pad limiting groups are then moved closer to each other by the third connecting plate 45 until the two sides of the rubber pad are inserted into the slots 47 on both sides, thus limiting the rubber pad. Then, the rubber pad is lifted by the two-axis moving platform 42 and moved towards the bottom shell until it is perpendicular to the bottom shell. Then, the rubber pad is brought close to the bottom shell, and the bottom column is inserted into the positioning hole. When the bottom column is inserted into the positioning hole, the control board transmission assembly 3 can cause the rubber pad to bend due to friction. After the bottom column limits the rubber pad, the control board positioning frame 36 releases the limit on the rubber pad, thus realizing the installation of the rubber pad.

[0073] To solve the technical problem of top cover transfer during sensor assembly, the present invention adopts a top cover transfer assembly 5, which includes a top cover transfer mechanism 51 disposed on one side of the workbench 1 and a top cover two-axis moving platform 52 mounted on the top surface of the workbench 1. A top cover finger cylinder 53 is disposed on one side of the top cover two-axis moving platform 52. The two grippers of the top cover finger cylinder 53 are fixedly connected to a second clamp 54, and the second clamp 54 has the same shape as the first clamp 24. A plurality of top cover positioning frames 55 are uniformly fixedly connected along the axis on the top surface of the top cover transfer mechanism 51, and the top cover positioning frames 55 have the same shape as the first bottom shell positioning frame 26. The top cover is located inside the top cover positioning frame 55.

[0074] Subsequently, when installing the top cover, first place the top cover inside each top cover positioning bracket 55, with the top sleeve of the top cover facing downwards. Then, move the top cover finger cylinder 53 towards the top cover using the top cover two-axis moving platform 52 until the two second clamps 54 are located on both sides of the top cover. Then, activate the top cover finger cylinder 53 to clamp the top cover using the two second clamps 54. Then, use the top cover two-axis moving platform 52 to vertically position the top cover above the bottom shell. Then, move the top cover vertically towards the bottom shell until the top cover and the bottom shell are in contact. At this time, the top sleeve should be fitted onto the surface of the bottom column and in contact with the rubber pad. After the top cover and the bottom shell are in close contact, the overall assembly of the sensor is achieved. At this time, the rubber pad is in close contact with the control board.

[0075] To solve the technical problem of overall pressing during sensor assembly, the present invention adopts a sensor overall transfer assembly 6 including a six-axis robotic arm 61 mounted on the top surface of the workbench 1. An integral finger cylinder 62 is installed at the connecting end of the six-axis robotic arm 61. Both grippers of the integral finger cylinder 62 are fixedly connected to a third clamp 63, and the third clamp 63 has the same shape as the first clamp 24. A fixing frame 64 is fixedly connected to the top surface of the workbench 1, and a pressing mechanism 65 is installed on the surface of the fixing frame 64.

[0076] To prevent a loose connection between the top cover and the bottom shell, a six-axis robotic arm 61 moves the integral finger cylinder 62 toward the assembled sensor until the third clamp 63 is positioned on both sides of the sensor. The integral finger cylinder 62 is then activated, causing the two third clamps 63 to hold the sensor. The six-axis robotic arm 61 then moves the sensor between the pressing mechanism 65 and the fixing frame 64. The cylinder inside the pressing mechanism 65 is then activated, and the pressure exerted by the cylinder on the sensor ensures a tighter connection between the bottom shell and the top cover. The rubber pad not only prevents the control board from shaking but also prevents direct pressure on the surface of the control board when the top cover is under pressure, reducing the possibility of the control board cracking during assembly.

[0077] After the above squeezing operation is completed, the staff needs to conduct a comprehensive inspection of the sensor to check whether the connection between the top cover and the bottom shell is tight and seamless, and to ensure that the rubber pad completely covers the control board without any offset. After such treatment, the overall assembly quality and stability of the sensor are significantly improved, which can effectively guarantee its performance and reliability in subsequent use.

[0078] To address the technical problem of intermittent movement of each component during sensor assembly, this invention employs a method where a plurality of diffuse reflective plate photoelectric sensors 25 are uniformly installed in a ring on the top surface of the workbench 1, and each diffuse reflective plate photoelectric sensor 25 is located on the side of the bottom shell conveying mechanism 21, the control board conveying mechanism 31, the rubber pad conveying mechanism 41, and the top cover conveying mechanism 51 close to the turntable 11.

[0079] Whenever the two-axis moving platform picks up a part from the surface of the conveyor mechanism, the diffuse reflective plate photoelectric sensor 25 detects the missing part and then restarts the conveyor mechanism. Through the rolling of the conveyor mechanism, timely replenishment is achieved.

[0080] It should be noted that this design cleverly utilizes the detection function of the diffuse reflector-type photoelectric sensor 25, forming a highly efficient linkage mechanism with the conveying mechanism. Specifically, when the two-axis moving platform removes a component, the diffuse reflector-type photoelectric sensor 25 can respond quickly, accurately detect the missing component, and immediately send a start signal to the conveying mechanism. Upon receiving the signal, the conveying mechanism quickly begins to roll, transporting the new component to the designated position, thereby ensuring the continuity and stability of the assembly process and greatly improving assembly efficiency. The diffuse reflector-type photoelectric sensor 25, model HPJ-A21, has its transmitter and receiver integrated and is directly aimed at the object. The sensor receives light reflected from the object's surface, thus achieving detection. Those skilled in the art can configure it according to actual needs, which will not be elaborated here.

[0081] It should be noted that the two-axis moving platform 22 of the bottom shell includes a horizontal electric push rod, a vertical electric push rod, a horizontal guide rail, a vertical guide rail, a slider, a positioning plate, and a mounting plate, etc. The horizontal and vertical movement methods can be set by those skilled in the art according to actual needs, and will not be elaborated here.

[0082] It should be noted that the bottom shell conveying mechanism 21 includes a conveyor belt, pulleys, tensioning mechanism, motor and protective shell, etc. Those skilled in the art can set it according to actual needs, which will not be described in detail here.

[0083] The assembly equipment for processing automotive rain sensors involves the following steps during use:

[0084] S1: When the bottom shell needs to be transferred, first, place the bottom shell inside each first bottom shell positioning frame 26. Limit the bottom shell by the four columns of the first bottom shell positioning frame 26, so that the bottom shells on the surface of the bottom shell conveying mechanism 21 are all on the same axis. Then, start the lateral movement mechanism inside the bottom shell two-axis moving platform 22. Move the bottom shell finger cylinder 23 to a position on the same vertical axis as the first bottom shell positioning frame 26 through the lateral movement mechanism. Then, move the bottom shell finger cylinder 23 closer to the first bottom shell positioning frame 26 through the vertical movement mechanism inside the bottom shell two-axis moving platform 22 until the two first clamps are in place. When 24 are located on both sides of the bottom shell, the bottom shell finger cylinder 23 is activated, and the two grippers approach the bottom shell and clamp it. Then, the bottom shell is lifted by the horizontal and vertical moving mechanism and moved to the top of the turntable 11, perpendicular to one of the second bottom shell positioning frames 27. Then, the bottom shell is placed inside the second bottom shell positioning frame 27 by the bottom shell two-axis moving platform 22. The second bottom shell positioning frame 27 limits the bottom shell again. Then, the worktable 1 is activated, and the bottom shell is moved by the second bottom shell positioning frame 27 to align with the control board conveying assembly 3, thus achieving precise positioning and transfer of the bottom shell.

[0085] S2: When the control board needs to be placed inside the bottom shell, first place the control board on the top surface of each control board positioning bracket 36, with the ejector pin of the control board facing the two limit blocks. This supports the control board while also determining its orientation and limiting its position. Then, activate the two-axis moving platform 32 of the control board. The second connecting plate 34 is moved closer to the control board through the two-axis moving platform 32 until the two belt sets 35 are located on both sides of the control board and are lower than the bottom surface of the control board. When the control board finger cylinder 33 approaches the control board from the vertical direction, the rubber pressure block 39 will contact the top surface of the control board. The rubber pressure block 39 will be forced and slide upward inside the first slide cylinder 37 until the belt set 35 is lower than the bottom surface of the control board. Then, activate the control board finger cylinder 33. The two second connecting plates 34 will drive the two belt sets 35 to move closer to each other. The two belt sets 35 will move closer to each other on the bottom surface of the control board, thus "lifting" the control board and avoiding the traditional method. The clamping mechanism formed by the two sides of the control board being pressed together can prevent the control board from tilting due to its thinness, as is the case with the two belt assemblies 35. When the control board is lifted by the two belt assemblies 35, the rubber pressure block 39 will press against the top surface of the control board due to gravity. This not only limits the control board with pressure but also keeps it in a horizontal position. When the control board is moved vertically to the bottom shell by the two-axis moving platform 32 and the bottom surface of the belt assembly 35 is aligned with the opening of the bottom shell, the control board finger cylinder 33 will use the grippers to move the two belt assemblies 35 away from each other. The control board will then rotate due to friction via the belt of the third connecting plate 45, thereby reducing friction on the control board. This prevents the placement position from shifting due to greater friction on one side when the control board is released. When the two belt assemblies 35 release their restraint on the control board, the rubber pressure block 39 will move the control board into the bottom shell due to gravity without tilting, thus achieving proper placement of the control board.

[0086] S3: When the rubber pad finger cylinder 44 is moved to a position on the same vertical axis as the rubber pad support frame 411 by the rubber pad two-axis moving platform 42 and close to the rubber pad until the rubber pad in the slot 47 is parallel to the same line, the two sets of rubber pad limiting groups are driven to move closer to each other by the third connecting plate 45 until the two sides of the rubber pad are inserted into the slots 47 on both sides to limit the rubber pad. Then the rubber pad is lifted by the rubber pad two-axis moving platform 42 and moved towards the bottom shell until it is perpendicular to the bottom shell. Then the rubber pad is close to the bottom shell, and the bottom column is inserted into the positioning hole. When the bottom column is inserted into the positioning hole, the rubber pad is bent due to friction. After the bottom column limits the rubber pad, the limit of the rubber pad by the control plate positioning frame 36 is released, thereby realizing the installation of the rubber pad.

[0087] S4: When installing the top cover, first place the top cover inside each top cover positioning bracket 55, with the top sleeve of the top cover facing down. Then, move the top cover finger cylinder 53 towards the top cover using the top cover two-axis moving platform 52 until the two second clamps 54 are located on both sides of the top cover. Then, activate the top cover finger cylinder 53 and clamp the top cover using the two second clamps 54. Then, use the top cover two-axis moving platform 52 to vertically set the top cover above the bottom shell. Then, move the top cover vertically towards the bottom shell until the top cover and the bottom shell are in contact. At this time, the top sleeve should be fitted onto the surface of the bottom column and in contact with the rubber pad. After the top cover and the bottom shell are in close contact, the overall assembly of the sensor is achieved. At this time, the rubber pad is in close contact with the control board.

[0088] S5: To avoid a loose connection between the top cover and the bottom shell, the six-axis robotic arm 61 moves the integral finger cylinder 62 toward the assembled sensor until the third clamp 63 is located on both sides of the sensor. The integral finger cylinder 62 is activated so that the two third clamps 63 clamp the sensor. Then, the six-axis robotic arm 61 moves the sensor between the pressing mechanism 65 and the fixing frame 64. Then, the cylinder inside the pressing mechanism 65 is activated. By squeezing the sensor with the cylinder, the connection between the bottom shell and the top cover is made tighter. The rubber pad not only prevents the control board from shaking, but also prevents the pressure on the top cover from directly affecting the surface of the control board, reducing the possibility of the control board cracking during assembly.

[0089] S6: Whenever the two-axis moving platform takes a part from the surface of the conveyor mechanism, the diffuse reflective plate photoelectric sensor 25 will detect the missing part, and then start the conveyor mechanism again. Through the rolling of the conveyor mechanism, timely replenishment is achieved.
