Description

Technical Field

[0001] This invention relates to the field of laser measurement technology, specifically to a controller housing line laser measurement device. Background Technology

[0002] After the controller housing is manufactured, its mounting surface undergoes flatness measurement. One of the most common methods is using a line laser 3D camera. A line laser 3D camera projects a laser line emitted from a laser onto the surface of the object being measured. An image sensor captures the image of the object's surface with the laser line. The laser line creates stripes of varying brightness on the surface, and the positions of these stripes change with the shape of the object's surface. Therefore, by analyzing these stripe position changes, combined with the known geometric relationship between the laser and the camera, and the angle between the laser line and the object's surface, the depth information of each point corresponding to a stripe is calculated using the principle of triangulation. Ultimately, the flatness of the object's surface can be measured.

[0003] When measuring the flatness of the controller housing surface, line laser 3D cameras project laser lines emitted from a laser onto the surface of the object being measured, forming stripes of varying brightness. The depth information of each stripe's corresponding point is calculated by analyzing the changes in its position. If dust particles adhere to the object's surface, they directly interfere with the changes in the stripe position formed by the laser line, leading to inaccurate measurement results. To prevent dust particles from adhering to the object's surface, existing line laser measurement equipment incorporates a dust removal mechanism to clean away the dust particles, ensuring the object's surface remains clean. For example, the invention patent with application number 202510257172.5 disclosed a workbench with guide rails. A slide plate is engaged with the guide rails, and a drive motor is located at one end of the guide rails. A threaded rod is located at the output end of the drive motor, and the threaded rod is threadedly connected to the slide plate. A clamping and fixing assembly is located on the top surface of the slide plate. Along the direction of travel of the slide plate on the guide rails, the workbench is sequentially equipped with a flatness detection assembly and a dust collection and suction assembly. The dust collection and suction assembly includes air knives and a vacuum conveyor positioned opposite each other on both sides of the guide rails. The object to be tested is clamped and fixed by the clamping and fixing assembly. The drive motor drives the slide plate, which holds the object to be tested, to move unidirectionally along the axis of the threaded rod to transport the object. Before the object reaches the workstation, the air knives in the dust collection and suction assembly blow up the dust adhering to the object, and then the vacuum conveyor in the assembly sucks away the blown dust, thus cleaning the surface of the object and effectively improving the accuracy of the measurement.

[0004] However, long-term operation has revealed that existing measuring equipment still has technical shortcomings that urgently need improvement. As is well known, air knife dust removal works by having air from a high-pressure blower enter the air knife and then be blown out at high speed through a thin sheet of air only 0.05 mm thick. Through the Coanda effect and the special geometry of the air knife, this thin air curtain can reach 30-40 times the volume of ambient air, forming a thin, high-intensity, large-airflow impact curtain that exits from the air knife's blade. The impact force of this air curtain easily blows up dust, thus achieving excellent dust removal efficiency. Furthermore, the air knife's blade is designed to be flat to create a wide and uniform airflow outlet, thereby improving dust removal efficiency. Due to space constraints and the direction of travel of the test object, and to ensure good dust collection efficiency of the vacuum conveyor, it needs to be positioned directly opposite the air knife to minimize the distance between them. Simultaneously, the dust blown by the air knife should flow towards the vacuum conveyor, maximizing its dust collection efficiency. Therefore, the air knife should not be installed in front of or behind the test object's path, as this would negatively impact the loading and unloading of the control unit, the operator's visibility, the aesthetics of the equipment layout, and the movement of the control unit. The air knife and vacuum conveyor should also not be staggered, as this would reduce the vacuum conveyor's dust collection efficiency. Therefore, the best arrangement remains the existing technology, where the air knife and vacuum conveyor are positioned directly opposite each other on the left and right sides of the test object's path. Meanwhile, the flat blade opening of the air knife cannot be too large, otherwise the high-pressure dust removal capacity of the airflow will be greatly reduced. If the blade opening is too small, the width of the controller housing surface covered by the blown airflow will be reduced, resulting in a very limited surface area covered by the air curtain-like airflow blown by the air knife. This makes it difficult to cover a larger area of ​​the housing surface, thus resulting in an unsatisfactory dust removal effect on the housing surface. Moreover, in order to ensure the accuracy of the measurement when the controller housing is transported to the measurement station, additional manual or electric operation is required for the fixing component to fix the controller housing in a specific position. Manual operation of the fixing component will undoubtedly increase the energy and time consumption of the operator, while electric operation of the fixing component requires additional electric drive components, which increases the manufacturing and maintenance costs of the equipment. Therefore, how to fix the controller housing with the fixing components without having to operate the fixing components separately, and how to effectively increase the surface area of ​​the controller housing covered by the airflow blown by the air knife to improve the dust removal effect of the controller housing when the air knife and vacuum conveyor are set opposite each other on the left and right sides of the controller housing's travel path, without increasing the opening degree of the air knife blade, are urgent technical problems to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a controller housing line laser measurement device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a controller housing line laser measurement device, comprising a feeding table slidably disposed on a worktable, a driving mechanism for driving the feeding table to reciprocate, and an air knife located on one side of the feeding table, wherein a tray for placing the controller housing is elastically slidably disposed on the feeding table.

[0007] A pusher block is slidably disposed on the tray;

[0008] The workbench is fixedly equipped with an inclined guide rail that slides into the push block;

[0009] During the process of the feeding table moving towards the measuring station, the inclined guide rail pushes the push block to abut against the controller housing to clamp and fix the controller housing, and then pushes the pallet to move elastically in the direction perpendicular to the feeding table so as to drive the controller housing to move relative to the air knife in the direction perpendicular to the feeding table.

[0010] As described above, the top of the tray is provided with a receiving groove adapted to the controller housing for placing the controller housing, and the tray is provided with a channel for the push block to pass through and communicate with the receiving groove.

[0011] As described above, a first end rod is installed on the top of the push block, and a second end rod is fixedly installed on the feeding table by a fixing plate. A folding curtain is connected between the first end rod and the second end rod, and the folding curtain is located above the inclined guide rail to cover the inclined guide rail.

[0012] As described above, when the controller housing is not placed on the pallet, during the process of the feeding table moving towards the measuring station, the inclined guide rail is driven to push the push block to slide so that the push block pulls the folding curtain across and blocks the receiving groove on the pallet via the first end rod.

[0013] As described above, the push block of the receiving groove on the folding curtain shielding plate abuts against the inner wall of the receiving groove of the plate so that the plate limits the push block.

[0014] As described above, the top of the push block is provided with a guide groove, the inclined guide rail is slidably disposed in the guide groove, and the end of the push block that abuts against the controller housing is the abutment part, which is located on the side of the first end rod close to the controller housing.

[0015] As described above, linear guide rails are fixedly installed on both the left and right sides of the pallet, and guide grooves are opened on the opposite surfaces of the two linear guide rails. Long sliders are fixedly installed on both the left and right sides of the push block through fixing rods, and the two long sliders are slidably arranged in the guide grooves of the two linear guide rails in a one-to-one correspondence.

[0016] As described above, two oppositely arranged second slide rails are fixedly installed on the top of the feeding platform, and wing plates are fixedly installed on both the left and right sides of the pallet. A set of second sliders is fixedly installed on the bottom of each of the two wing plates, and the two sets of second sliders are slidably engaged with the two second slide rails one by one.

[0017] As described above, a first cleaning component is fixedly installed at the bottom of the first end rod. The first cleaning component includes a first plug plate and two first oil-absorbing cottons. The two first oil-absorbing cottons are pressed and inserted into the two ends of the first plug plate in a corresponding manner. The ends of the two first oil-absorbing cottons that are far apart from each other are inserted into the guide grooves of the two linear guide rails in a corresponding manner.

[0018] As described above, a second cleaning component is fixedly installed at the bottom of the tray. The second cleaning component includes a second plug plate and a second oil-absorbing cotton. The second oil-absorbing cotton is pressed and inserted under the second plug plate. The ends of the two second oil-absorbing cotton that are far apart from each other are in contact with the opposite surfaces of the two second slide rails.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention, by elastically sliding a tray on a feeding table, sliding a pusher block on the tray, and fixing a slanted guide rail slidably connected to the pusher block, allows the pusher block to automatically fix the controller housing during the feeding table's movement to the measuring station. Furthermore, after fixing the controller housing, the pusher block cleverly utilizes the controller housing's blocking effect to move the controller housing in a direction perpendicular to the feeding table. This creates a displacement between the controller housing and the air knife perpendicular to the feeding table's direction of travel. This allows the high-pressure airflow from the air knife to sweep across the controller housing's surface, significantly increasing the surface area covered by the high-pressure airflow and thus improving dust removal efficiency. Therefore, this invention can fix the controller housing without requiring separate operation of the fixing components. It also effectively increases the surface area covered by the airflow from the air knife, improving dust removal efficiency, even when the air knife and vacuum conveyor are positioned opposite each other on the left and right sides of the controller housing's travel path, without increasing the air knife's blade opening. This effectively overcomes the shortcomings of existing technologies.

[0021] 2. In this invention, the fixing of the controller housing and the displacement between the controller housing and the air knife perpendicular to the direction of the feeding table to improve the dust removal effect on the surface of the controller housing are automatically achieved during the process of the feeding table moving to the measuring station. There is no additional separate operation throughout the process, and no interruption is required, which can effectively improve work efficiency.

[0022] 3. In this application, by setting up a folding curtain, the folding curtain not only serves to prevent dust from entering the inclined guide rail during the movement of the feeding table towards the measuring station when the controller housing is being measured, through the continuous pulling of the push block, but also, under the specific structural design of this application, when the controller housing is not placed on the pallet, the push block is no longer obstructed by the controller housing during the movement of the feeding table towards the measuring station. At this time, the push block can further pull the folding curtain to extend until the folding curtain covers the receiving groove on the pallet, so that the folding curtain automatically achieves the function of preventing dust from entering the receiving groove on the pallet. Both involve the feeding table moving towards the measuring station, but the folding curtain has different functions depending on whether the controller housing is placed on the pallet or not, achieving two goals at once.

[0023] 4. In this application, by installing a first cleaning component at the bottom of the first end rod, the first plug-in plate on the first cleaning component can block dust, thus providing a better dustproof effect for the inclined guide rail. Simultaneously, the first oil-absorbing cotton on the first cleaning component not only absorbs excess lubricating oil in the guide groove of the linear guide rail, but also cleverly uses the absorbed lubricating oil to remove dust adhering to the guide groove, thereby cleaning the guide groove of the linear guide rail. Furthermore, the functions of the first oil-absorbing cotton in absorbing excess lubricating oil in the guide groove of the linear guide rail and removing dust adhering to the guide groove are automatically achieved during the process of the receiving groove on the folding curtain cover plate, requiring no additional operation and effectively improving work efficiency.

Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] The terms relating to direction and position used in this application are relative to the accompanying drawings.

[0051] First embodiment:

[0052] Please see the appendix Figure 1-19 The present invention provides a technical solution: a controller housing line laser measurement device, including a feeding table 3 slidably disposed on a worktable 23, a driving mechanism for driving the feeding table 3 to reciprocate and slide, and an air knife 18 located on one side of the feeding table 3. A tray 5 for placing the controller housing 4 is elastically slidably disposed on the feeding table 3.

[0053] A pusher block 6 is slidably mounted on the tray 5;

[0054] An inclined guide rail 7 is fixedly installed on the workbench 23 and slides into the push block 6;

[0055] During the process of the feeding table 3 moving towards the measuring station, the inclined guide rail 7 pushes the push block 6 to abut against the controller housing 4 to clamp and fix the controller housing 4, and then pushes the pallet 5 to move elastically in the direction perpendicular to the feeding table 3 so as to drive the controller housing 4 to move relative to the air knife 18 in the direction perpendicular to the feeding table 3.

[0056] Specifically, this embodiment includes a cabinet 2, a workbench 23 fixedly installed on the top of the cabinet 2, an upper box 1 fixedly installed on the workbench 23, the upper box 1 enclosing a frame, a top plate fixedly installed on the top of the frame, and a side door that can be opened and installed on the frame. Two first slide rails 14 arranged opposite to each other are fixedly installed on the workbench 23. Pads 12 are fixedly installed on both sides of the bottom of the feeding table 3. A set of first sliders 13 is fixedly installed on the bottom of each of the two pads 12. The two sets of first sliders 13 are slidably engaged with the two first slide rails 14. The number of first sliders 13 in each set of first sliders 13 is at least two. The drive mechanism includes a motor 15 fixedly mounted on the worktable 23. A lead screw 16 is coaxially keyed or coaxially fixedly connected to the power output shaft of the motor 15. A limit plate 303 is fixedly mounted on the bottom of the feeding table 3, located between the two sets of first sliders 13. The lead screw 16 is screwed to and passes through the limit plate 303. A bearing seat 102 is fixedly mounted on the worktable 23, and the end of the lead screw 16 is rotatably connected to the bearing seat 102. The motor 15 can rotate forward and reverse. By starting the motor 15, the lead screw 16 is driven to rotate. Based on the screw connection between the lead screw 16 and the limit plate 303, when the motor 15 drives the lead screw 16 to rotate forward, it drives the limit plate 303 and the feeding table 3 to move towards the measuring station. When the motor 15 drives the lead screw 16 to rotate in the reverse direction, it drives the limit plate 303 and the feeding table 3 to move away from the measuring station. Of course, the drive mechanism can also be replaced by other structures, as long as they can drive the feeding table 3 to slide back and forth. The workbench 23 is equipped with an air knife 18 and a vacuum conveyor arranged opposite each other. A bracket 17 is fixedly installed on the workbench 23, and the air knife 18 is fixedly installed on the bracket 17. The air knife 18 is also connected to a high-pressure blower through a connecting pipe (the connecting pipe and the high-pressure blower are not shown in the figure). The vacuum conveyor includes a suction hood 19, a negative pressure pipe 1901, a vacuum pump, and a filter (not shown in the figure). The negative pressure pipe 1901 is fixedly installed on the workbench 23 and passes through the workbench 23. The bottom of the workbench 23 extends into the interior of the cabinet 2. The vacuum pump and filter are located inside the cabinet 2. The specific structure and operating principle of the air knife 18 and the vacuum conveyor are existing technologies and will not be described in detail. The suction hood 19 and the air knife 18 are positioned opposite each other and are located on the left and right sides of the feeding platform 3 in the direction of travel. The high-pressure airflow blown out of the air knife 18 impacts the controller housing 4, causing the dust on the controller housing 4 to be blown up. Under the action of the negative pressure chamber of the suction hood 19, the blown dust is sucked into the suction hood 19 and finally filtered and retained in the vacuum conveyor. The length of the air knife 18 air outlet in the direction of travel of the feeding platform 3 is greater than the length of the controller housing 4.

[0057] The feeding platform 3 has a sliding support plate 5 on top, and a pusher block 6 on the support plate 5. The sliding directions of both the pusher block 6 and the support plate 5 relative to the feeding platform 3 are perpendicular to the traveling direction of the feeding platform 3. When the feeding platform 3 moves, it causes the support plate 5 and the pusher block 6 to move synchronously in the traveling direction of the feeding platform 3. The support plate 5 is used to place the controller housing 4. When the support plate 5 moves, it causes the controller housing 4 to move synchronously. The pusher block 6 cooperates with the support plate 5 to clamp and fix the controller housing 4 between the pusher block 6 and the support plate 5. A fixed plate 302 is fixedly installed on the feeding table 3. A connecting plate 503 opposite to the fixed plate 302 is fixedly installed on the bottom of the pallet 5. A tension spring 11 is connected between the connecting plate 503 and the fixed plate 302. One end of the tension spring 11 is fixedly connected to the connecting plate 503, and the other end is fixedly connected to the fixed plate 302. A limiting plate 303 is fixedly installed on the feeding table 3, which abuts against the end face of the pallet 5. The abutment between the end face of the pallet 5 and the limiting plate 303 keeps the tension spring 11 in a stretched state, so that the relative sliding resistance between the pallet 5 and the feeding table 3 is greater than the relative sliding resistance between the push block 6 and the pallet 5. The end face of the pallet 5 is always in contact with the limiting plate 303 before the push block 6 abuts against the controller housing 4. The inclined guide rail 7 is located above the pallet 5. The inclined guide rail 7 has a specific angle with the traveling direction of the feeding table 3. The degree of the angle is not fixed and can be determined according to the actual stroke length of the feeding table 3. The inclined guide rail 7 and the push block 6 are slidably engaged. The top of the push block 6 is provided with a guide groove 601, which is parallel to the inclined guide rail 7. The inclined guide rail 7 is slidably engaged in the guide groove 601. The end of the push block 6 that abuts against the controller housing 4 is the abutment part 603, which is located on the side of the first end rod 9 near the controller housing 4. When the feeding table 3 drives the push block 6 to move in the traveling direction of the feeding table 3, the inclined guide rail 7 pushes the push block 6 to slide in a direction perpendicular to the traveling direction of the feeding table 3 due to the inclined setting of the inclined guide rail 7. When the feeding platform 3 is located at the position furthest from the measuring station, the push block 6 does not contact the controller housing 4 in the tray 5. At this time, the controller housing 4 is in a non-fixed state, which facilitates the placement and removal of the controller housing 4. When the feeding platform 3 moves toward the measuring station, the feeding platform 3 drives the tray 5 and the push block 6 to move synchronously. The movement of the push block 6 causes it to slide relative to the inclined guide rail 7, so that the inclined guide rail 7 pushes the push block 6 toward the controller housing 4. When the abutting part 603 abuts against the controller housing 4, the controller housing 4 is clamped and fixed by the push block 6 and the tray 5. There is no need to perform a separate operation to fix the controller housing 4, which eliminates the action of separately operating the fixing components to fix the controller housing 4 in the prior art.

[0058] Furthermore, cleverly, after the controller housing 4 is clamped and fixed by the push block 6 and the tray 5, as the feeding table 3 moves further toward the measuring station, the inclined guide rail 7 pushes the push block 6, which in turn pushes the controller housing 4 and the tray 5 to move synchronously in a direction perpendicular to the feeding table 3. This results in the controller housing 4 being moved by the feeding table 3 in its direction of travel while being pushed by the push block 6 in a direction perpendicular to the feeding table 3. The air knife 18 is located in a direction perpendicular to the feeding table 3. Therefore, when the controller housing 4 moves in a direction perpendicular to the feeding table 3, the high-pressure airflow blown out by the air knife 18 will sweep and impact the surface of the controller housing 4, thereby greatly increasing the surface area of ​​the controller housing 4 covered by the high-pressure airflow and thus improving the dust removal effect.

[0059] Therefore, this invention, by elastically sliding a tray 5 on the feeding table 3, sliding a pusher 6 on the tray 5, and fixing an inclined guide rail 7 that is slidably connected to the pusher 6, enables the pusher 6 to automatically fix the controller housing 4 before the feeding table 3 moves to the measuring station. Furthermore, after fixing the controller housing 4, the pusher 6 cleverly utilizes the blocking effect of the controller housing 4 on the pusher 6 to push the controller housing 4 in a direction perpendicular to the feeding table 3. This causes a displacement between the controller housing 4 and the air knife 18 perpendicular to the direction of travel of the feeding table 3. This allows the high-pressure airflow from the air knife 18 to sweep across the surface of the controller housing 4, thereby greatly increasing the surface area of ​​the controller housing 4 covered by the high-pressure airflow and improving the dust removal effect. It is evident that the present invention can fix the controller housing by the fixing component without the need for separate operation of the fixing component. Furthermore, it can effectively increase the surface area of ​​the controller housing covered by the airflow blown out by the air knife, thereby improving the dust removal effect, even when the air knife and vacuum conveyor are set opposite each other on the left and right sides of the controller housing's travel path and without increasing the opening degree of the air knife blade. This effectively solves the shortcomings of the prior art.

[0060] Moreover, since the fixing of the controller housing 4 and the displacement between the controller housing 4 and the air knife 18 perpendicular to the direction of travel of the feeding table 3 to improve the dust removal effect on the surface of the controller housing 4 are automatically achieved during the process of the feeding table 3 moving to the measuring station, there is no additional separate operation throughout the process, and no interruption is required, which can effectively improve work efficiency.

[0061] In this embodiment, a mounting frame 20 is fixedly installed on the workbench 23, and a line laser 3D camera 21 is fixedly installed on the mounting frame 20. The structure and principle of the line laser 3D camera 21 are existing technologies and will not be described in detail. The measurement station is directly below the line laser 3D camera 21. When the feeding table 3 moves to the measurement station, the controller housing 4 is located below the line laser 3D camera 21 to perform line laser measurement on the surface of the controller housing 4. The controller housing 4 can be measured at a fixed point or during movement, both of which are achieved by moving and stopping the feeding table 3. A light shield 22 is also fixedly installed on the mounting frame 20 to block light so that the laser line emitted by the light shield 22 is projected onto the surface of the object to be measured more clearly and to reduce light interference. The light shield 22 has a notch for the feeding table 3, the support plate 5, the controller housing 4, the push block 6, and other structures that move synchronously with the feeding table 3 to pass through.

[0062] In this embodiment, the top of the tray 5 is provided with a receiving groove that is adapted to the controller housing 4 for placing the controller housing 4. The tray 5 is provided with a channel for the push block 6 to pass through and communicate with the receiving groove. When the push block 6 is pushed and fixed by the inclined guide rail 7, the push block 6 moves along the channel on the tray 5.

[0063] Furthermore, a first end rod 9 is installed on the top of the push block 6, and a second end rod 10 is fixedly installed on the feeding table 3 via a fixing plate 302. A folding curtain 8 is connected between the first end rod 9 and the second end rod 10. The folding curtain 8 is located above the inclined guide rail 7 to shield the inclined guide rail 7. Furthermore, the inclined guide rail 7 is located on the opposite side of the air knife 18, so that when the airflow blown out by the air knife 18 impacts the surface of the controller housing 4, the dust blown up can easily adhere to the inclined guide rail 7, thereby increasing the friction between the inclined guide rail 7 and the push block 6 and accelerating wear. For this reason, a folding curtain 8 is added in this embodiment. The folding curtain 8 is located above the inclined guide rail 7, and the minimum distance between the folding curtain 8 and the inclined guide rail 7 is less than 3mm. The folding curtain 8 shields the part of the inclined guide rail 7 located directly above the support plate 5, so that the dust blown up from the controller housing 4 is not easily adhered to the inclined guide rail 7, thus achieving the function of protecting the inclined guide rail 7.

[0064] Specifically, the top of the push block 6 is provided with an installation groove 602. The first end rod 9 is fixedly installed in the installation groove 602 to reduce the top height of the first end rod 9, thereby reducing the distance between the folding curtain 8 and the inclined guide rail 7. The folding curtain 8 is a foldable structure. The structure of the folding curtain 8 is existing technology and will not be described in detail. One end of the folding curtain 8 is fixedly connected to the first end rod 9 and the other end is fixedly connected to the second end rod 10. The first end rod 9 is fixedly connected to the push block 6, and the second end rod 10 is fixedly connected to the feeding table 3. Therefore, as the feeding table 3 moves, as the inclined guide rail 7 continuously pushes the push block 6 to move, the push block 6 can stretch the folding curtain 8 through the first end rod 9 so that the folding curtain 8 can always cover the part of the inclined guide rail 7 located directly above the support plate 5, thereby making it difficult for dust blown on the controller housing 4 to adhere to the inclined guide rail 7.

[0065] Furthermore, since it is difficult to achieve the requirements of a cleanroom in the working environment, when the equipment is not used for a long time, dust in the workshop is very easy to adhere to the pallet 5. Once the dust accumulates in the receiving groove of the pallet 5, it will affect the accurate positioning of the controller housing 4 when it is placed next time. Therefore, the ingenuity of this invention is that when the controller housing 4 is not placed on the pallet 5, the controller housing 4 will not abut against the push block 6. After the push block 6 is no longer blocked by the controller housing 4, it drives the inclined guide rail 7 to push the push block 6 to slide during the movement of the feeding table 3 towards the measuring station. This allows the push block 6 to pull the folding curtain 8 through the first end rod 9 to pass over and cover the receiving groove on the pallet 5. The pallet 5 not only moves to the inside of the equipment, but the receiving groove on the pallet 5 is also covered by the folding curtain 8, making it difficult for external dust to enter the receiving groove. It can be seen that the folding curtain 8 also plays the role of preventing dust in the receiving groove on the pallet 5, and no manual operation is required.

[0066] Therefore, by setting up the folding curtain 8 in this application, the folding curtain 8 not only provides dust protection to the inclined guide rail 7 during the movement of the feeding table 3 toward the measuring station when the controller housing 4 is being measured, through the continuous pulling of the push block 6, but also, under the specific structural design of this application, when the controller housing 4 is not placed on the pallet 5, the push block 6 is no longer obstructed by the controller housing 4 during the movement of the feeding table 3 toward the measuring station. At this time, the push block 6 can further pull the folding curtain 8 to extend until the folding curtain 8 covers the receiving groove on the pallet 5, so that the folding curtain 8 automatically provides dust protection to the receiving groove on the pallet 5. Both cases involve the feeding table 3 moving toward the measuring station, but the folding curtain 8 has different functions depending on whether the controller housing 4 is placed on the pallet 5 or not, achieving two goals at once.

[0067] In this embodiment, the folding curtain 8 covers the receiving groove on the tray 5, and the push block 6 abuts against the inner wall of the receiving groove of the tray 5 so that the tray 5 limits the push block 6 and prevents the push block 6 from separating from the tray 5.

[0068] The top of the feeding platform 3 is fixedly equipped with two oppositely arranged second slide rails 301. Wing plates 501 are fixedly installed on both the left and right sides of the pallet 5. A set of second sliders 504 is fixedly installed at the bottom of each of the two wing plates 501. The two sets of second sliders 504 are slidably engaged with the two second slide rails 301 in a one-to-one correspondence. The number of second sliders 504 in each set of second sliders 504 is at least two. The sliding connection between the pallet 5 and the feeding platform 3 is achieved by the sliding engagement of the second sliders 504 with the second slide rails 301.

[0069] In this embodiment, linear guide rails 502 are fixedly installed on both the left and right sides of the support plate 5. The two linear guide rails 502 are fixedly installed on the top of the two wing plates 501 one by one. The opposite surfaces of the two linear guide rails 502 are provided with guide grooves. The two sides of the push block 6 are fixedly installed with long sliders 25 by fixing rods 24. The two long sliders 25 are slidably disposed in the guide grooves of the two linear guide rails 502 one by one. The sliding connection between the push block 6 and the support plate 5 is realized by the sliding connection between the two long sliders 25 and the guide grooves of the two linear guide rails 502.

[0070] In this embodiment, two support columns 101 are fixedly installed on the top of the workbench 23 (only one support column 101 is shown in the figure), and the two ends of the inclined guide rail 7 are fixedly connected to the two support columns 101 one by one by bolts (not shown in the figure). The inclined guide rail 7 and the first end rod 9 are staggered in both the height direction and the horizontal direction.

[0071] Second embodiment:

[0072] This embodiment uses the same technical features as the first embodiment, but differs in that:

[0073] Please see the appendix Figure 20-22A first cleaning component 27 is fixedly installed at the bottom of the first end rod 9. The first cleaning component 27 includes a first plug plate 2701 and two first oil-absorbing cottons 2702. Both ends of the first plug plate 2701 are provided with slots (not shown in the figure). The two first oil-absorbing cottons 2702 are pressed into the slots at both ends of the first plug plate 2701 in a corresponding manner. The ends of the two first oil-absorbing cottons 2702 that are far apart from each other are inserted into the guide grooves of the two linear guides 502 in a corresponding manner. The first oil-absorbing cottons 2702 abut against the inner wall of the guide groove of the linear guide 502. Specifically, since the two linear guides 502 are located on the left and right sides of the support plate 5, when dust on the controller housing 4 is blown up, the dust easily adheres to the inner wall of the guide groove of the linear guide 502 because the guide groove of the linear guide 502 is coated with lubricating oil. This increases wear when the long slider 25 slides in the guide groove. Moreover, when lubricating oil is applied to the guide groove of the linear guide 502, excess lubricating oil will drip onto the wing plate 501, causing contamination. Therefore, in this embodiment, by fixing the first cleaning component 27 to the bottom of the first end rod 9, when the controller housing 4 is not placed on the tray 5, as the first end rod 9 pulls the folding curtain 8 to continuously extend and cover the receiving groove on the tray 5, the first end rod 9 can also drive the first cleaning component 27 to move synchronously, so that the first oil-absorbing cotton 2702 on the first cleaning component 27 slides in the guide groove of the linear guide rail 502. As the first oil-absorbing cotton 2702 slides, it absorbs the excess lubricating oil in the guide groove of the linear guide rail 502, and uses the excess lubricating oil absorbed in the first oil-absorbing cotton 2702 to remove the dust adhering to the guide groove. Moreover, the distance between the bottom of the first plug plate 2701 and the top surface of the support plate 5 is no more than 1mm, and the first plug plate 2701 is tightly fitted with the outer side of the push block 6, so that the first plug plate 2701 can block dust, making it difficult for the dust blown up to pass through the gap between the first end rod 9 and the support plate 5 and adhere to the inclined guide rail 7. Thus, the first plug plate 2701 can provide better dust protection for the inclined guide rail 7.

[0074] Therefore, by installing a first cleaning component 27 at the bottom of the first end rod 9, the first plug-in plate 2701 on the first cleaning component 27 can block dust, thus providing a better dustproof effect for the inclined guide rail 7. Simultaneously, the first oil-absorbing cotton 2702 on the first cleaning component 27 not only absorbs excess lubricating oil in the guide groove of the linear guide rail 502, but also cleverly uses the absorbed lubricating oil to remove dust adhering to the guide groove, thereby cleaning the guide groove of the linear guide rail 502. Furthermore, the functions of the first oil-absorbing cotton 2702 in absorbing excess lubricating oil in the guide groove of the linear guide rail 502 and removing dust adhering to the guide groove using the absorbed lubricating oil are automatically achieved during the process of the folding curtain 8 covering the receiving groove on the support plate 5, requiring no additional operation and effectively improving work efficiency.

[0075] Furthermore, in order to improve the smoothness of sliding, lubricating oil needs to be applied to the two second slide rails 301 from time to time. Although the lubricating oil can play a lubricating role, since the controller housing 4 is located between the two second slide rails 301, when dust on the controller housing 4 flies up, the lubricating oil on the opposite surface of the two second slide rails 301 is also very easy to attract dust, which will increase the wear between the second slide rails 301 and the second slider 504. Moreover, excess lubricating oil will fall on the feeding table 3 and be contaminated. Therefore, in this embodiment, a second cleaning component 26 is fixedly installed on the bottom side of the tray 5 away from the first end rod 9. The second cleaning component 26 includes a second plug plate 2601 and a second oil-absorbing cotton 2602. The bottom of the second plug plate 2601 has a rectangular inner groove (not shown in the figure). The inner groove passes through both ends of the second plug plate 2601. The second oil-absorbing cotton 2602 is pressed and inserted into the inner groove at the bottom of the second plug plate 2601 so that the second oil-absorbing cotton 2602 is located below the second plug plate 2601. The ends of the two second oil-absorbing cotton 2602 that are far apart from each other extend to the outside of the second plug plate 2601 and abut against the opposite surfaces of the two second slide rails 301 one by one. The end face shape of the second oil-absorbing cotton 2602 is adapted to the side shape of the second slide rail 301 so that the second oil-absorbing cotton 2602 fits better with the second slide rail 301.

[0076] When the controller housing 4 is placed on the tray 5, the inclined guide rail 7 pushes the push block 6, which in turn pushes the tray 5 and the controller housing 4 to slide. This causes the tray 5 to move synchronously with the second cleaning component 26. At this time, the second oil-absorbing cotton 2602 slides along the length of the second slide rail 301 to absorb excess lubricating oil and clean the dust adhering to the opposing surfaces of the two second slide rails 301 using the absorbed lubricating oil. Furthermore, the absorption of excess lubricating oil and the cleaning of dust adhering to the second slide rails 301 by the second oil-absorbing cotton 2602 are automatically achieved during the movement of the feeding table 3 toward the measuring station, requiring no additional operation and further improving work efficiency.

[0077] In this embodiment, when applying lubricating oil to the opposing surfaces of the two second slide rails 301 and the guide grooves of the two linear guide rails 502, in order to prevent the lubrication effect from being reduced due to insufficient lubricating oil, more lubricating oil can be applied. The extra lubricating oil will not drip and cause pollution, but will be absorbed by the first oil-absorbing cotton 2702 and the second oil-absorbing cotton 2602 for cleaning dust.

[0078] Furthermore, the bottom of the second oil-absorbing cotton 2602 abuts against the top surface of the feeding table 3. When the dust cleaned from the guide groove of the linear guide rail 502 falls onto the feeding table 3, the second oil-absorbing cotton 2602 can also clean up the dust that falls onto the feeding table 3. The cleaned dust can be stored in a storage box (not shown in the figure) at the end of the feeding table 3.

[0079] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources, and this application is equipped with a control system for controlling the operation of the entire equipment.
