Description

Technical Field

[0001] The utility model specifically relates to a full-automatic filter thread hole detection device. Background Technique

[0002] A filter is a device widely used in various machinery and automobiles, and its main function is to filter impurities. The finished filter has installation thread holes. During the production process of the filter, especially before the filter is warehoused, a series of inspections need to be carried out on the filter. Among them, the thread inspection in the installation hole is an essential process.

[0003] The Chinese invention patent application document with the publication number of "CN118293765A" introduces a full-automatic detection device, which consists of a frame, a feeding component, a transfer component, a clamping component, a detection component and a controller, realizing the automatic positioning, clamping and thread detection of the filter, and sending the detected filter to the qualified product area or the unqualified product area. Another Chinese invention patent document with the publication number of "CN104764426B" discloses a filter oil outlet thread detection and comparison device, including a handling manipulator, a filter full gauge rotation detection mechanism, etc., and the thread of the filter is detected by the cooperation of a speed regulating motor and a full gauge. From the above two published documents, the general process of filter thread hole detection in the prior art can be understood, which will inevitably involve three major modules: an automatic filter transportation module, an automatic filter thread hole detection module, and a filter clamping plate mechanism.

[0004] (1) Regarding the automatic filter thread hole detection module, the corresponding one in the document with the publication number of "CN104764426B" is the filter full gauge rotation detection mechanism. The full gauge mounting seat of this mechanism is linked with a coupling through a plunger screw, and the full gauge is fixedly installed on the full gauge mounting seat. During the filter thread detection process, both the full gauge and the full gauge mounting seat are fixed along the axis direction of the linear bearing, that is, they only rotate by themselves and do not move up and down with the filter. When the thread quality of the oil outlet of the filter is poor, the unqualified filter will inevitably spin or get stuck until the clamping force reaches the preloading force, at which time the plunger screw disengages from the full gauge mounting seat to protect the speed regulating motor, and the defective filter is picked out manually.

[0005] However, there are many problems with this design. First of all, when unqualified products occur, jamming will occur between the go gauge and the filter, and it is necessary to overcome the friction between the plunger screw and the go gauge mounting seat to protect the servo motor. This will inevitably exacerbate the wear of the plunger screw, the output rod of the servo motor, the go gauge, the threaded hole of the filter, etc., and these components need to be replaced frequently, resulting in high later maintenance costs and being time-consuming and laborious. Secondly, once defective products appear, it is necessary to manually remove the defective products in time, otherwise there will be a long-term jamming or the filter will rotate. This not only increases the workload of workers, but also poses a greater safety risk, especially when approaching the mechanical moving parts. Therefore, the design of the filter go gauge rotation detection mechanism is extremely unreasonable, which not only increases the maintenance difficulty and cost, but also affects the reliability and stability of the entire detection mechanism.

[0006] (2) Regarding the filter automatic transportation module, the document with the publication number "CN118293765A" discloses a transportation module composed of a feeding component and a transfer component. The feeding turntable in the feeding component is provided with a plurality of evenly arranged fan-shaped feeding notches on the outer circle for limiting and orderly transporting the filter. However, the sizes of these fan-shaped notches are fixed, resulting in each turntable being only suitable for a single specification of the filter. If different specifications need to be detected, the feeding turntable must be replaced, and this process becomes cumbersome because it involves linkage components such as the drive source and the conveyor belt. In addition, due to only relying on the fan-shaped notches for limiting, the filter is prone to shaking during transportation, affecting stability and reliability.

[0007] The transfer component includes two first transfer conveyor belts and one second transfer conveyor belt, which adopt a simple conveyor belt form and do not have a limiting structure. This results in the filter being prone to shaking, tipping, and even position deviation during movement, making it difficult for the clamping component to accurately align with the filter for clamping. To sum up, this transportation module has obvious deficiencies in terms of adaptability, stability, and operation efficiency.

[0008] (3) Regarding the filter clamping mechanism, the Chinese utility model patent document with the publication number "CN219819391U" discloses a product clamping mechanism for a filter leak detection device. The clamp consists of a main clamp, a sub-clamp, a clamp drive component, an elastic tensioning mechanism, and wear-resistant anti-slip blocks. The main clamp and the sub-clamp are designed with corresponding V-shaped clamping openings to form a quadrilateral clamping position to fix the filter. The clamp drive component realizes the relative movement between the clamps, and the elastic tensioning mechanism is located between the clamping positions to provide a clamping force.

[0009] Combined with the attached drawings of the specification of this published document Figure 4It can be clearly seen that the tension spring body 4 (i.e., the elastic tension mechanism) is arranged between the main fixture and the auxiliary fixture, and the hooks at both ends of the tension spring body 4 are respectively used to connect with the main fixture and the auxiliary fixture. This layout can only achieve the elastic change between the main fixture and the auxiliary fixture, and does not directly act on the filter in each V-shaped clamping opening. Moreover, due to the inevitable errors in the filter, V-shaped clamping opening, etc., the clamping force of each clamping opening on the filter is not in the best elastic change state. If there are significant differences in the clamping force between different clamping openings, then the filter may be displaced or overturned due to the loosening of some clamping openings during transportation. Utility Model Content

[0010] The technical problem to be solved by the present utility model is to provide a fully automatic filter thread hole detection device for the deficiencies of the above-mentioned prior art. The go gauge can float up and down. When the detected filter is unqualified, the go gauge will not get stuck with the filter, and the filter will not rotate.

[0011] To achieve the above object, the present utility model provides the following technical solutions: a fully automatic filter thread hole detection device, including a frame. A number of groups of thread detection holes are provided on the frame. A feeding device and a discharging transportation component are respectively provided on both sides of the number of groups of thread detection holes. A clamping device is provided above the number of groups of thread hole detection holes. A detection mechanism is provided in each group of thread detection holes. The clamping device can transport the filter to be detected transported by the feeding device into the detection mechanism for detection and transport the detected filter into the discharging transportation component. The detection mechanism includes a positioning die base and a first motor. A go gauge mounting seat is provided between the first motor and the positioning die base. A go gauge is connected above the go gauge mounting seat. A detection relief hole through which the go gauge can pass is provided through the middle of the positioning die base. The positioning die base is linked with a guiding component. A sensor is provided below the guiding component. It is characterized in that: the detection mechanism further includes a rotating sleeve rotatably inserted into the thread detection hole. The lower end of the rotating sleeve is linked with the output end of the first motor. A first square column is provided at the lower end of the go gauge mounting seat. A first square hole adapted to the first square column is provided in the rotating sleeve. The go gauge mounting seat is linked with a first spring.

[0012] This technical solution transports the filters in an orderly manner through the feeding device, and uses the clamping device to transport the filter to be detected to the detection mechanism at the thread detection hole for thread hole detection. Through the mutual cooperation of the guiding component and the sensor, the automatic detection and quality judgment of the filter thread hole are realized, and the adaptability of the fully automatic production line is achieved. The specific detection process is as follows: The clamping plate mechanism places the filter on the go-no-go gauge mounting seat, and then presses down the filter to facilitate the go-no-go gauge to contact the thread hole and detect the thread hole. During this process, the first motor drives the rotating sleeve to rotate, and the rotating sleeve drives the go-no-go gauge mounting seat to rotate through the linkage structure of "the first square column and the first square hole", and then drives the go-no-go gauge to rotate. If the filter is qualified, the go-no-go gauge is threadedly connected to the thread hole, and drives the filter to gradually move down until the preset position, where it will be detected by the sensor and a signal indicating that the product is qualified will be sent; if the filter is unqualified, the go-no-go gauge cannot be threadedly connected to the thread hole, but due to the design of the "first spring", the go-no-go gauge and the go-no-go gauge mounting seat will float downward, avoiding the phenomenon of the go-no-go gauge being stuck with the filter. In this way, the guiding component is also subjected to a more uniform force, improving the reliability and stability of the entire thread detection mechanism. And because the filter is unqualified, the go-no-go gauge will not be connected to the thread hole, so the unqualified filter will not move down a long distance, and the sensor will not send a detection signal. This is the unqualified filter, which is used to distinguish it from the qualified filter. At the same time, this will not affect the detection of qualified filters elsewhere. During this process, the first motor still rotates normally, also avoiding the occurrence of the first motor being overloaded. Further, since the unqualified filter will not spin or get stuck with the go-no-go gauge, there is no need to immediately manually remove the unqualified product. The unqualified filter can be removed after a single detection action is completed, reducing the workload of the workers and improving the safety of the working environment. Further, through the design of the first square column and the first square hole, the synchronous rotational connection between the go-no-go gauge mounting seat and the rotating sleeve is realized. This connection method enables the first motor to drive the rotating sleeve to rotate, thereby driving the go-no-go gauge mounting seat to rotate. The go-no-go gauge follows the rotation of the go-no-go gauge mounting seat to detect the thread hole of the filter. At the same time, by designing the first spring, the go-no-go gauge can float up and down. Under the downward pressing force of the filter, the go-no-go gauge and the go-no-go gauge mounting seat move downward relative to the rotating sleeve to facilitate the go-no-go gauge to detect the thread hole of the filter. When the detected filter is unqualified, the go-no-go gauge will not get stuck with the filter, and the filter will not spin either.

[0013] The above-mentioned fully automatic filter threaded hole detection equipment can be further configured as follows: a quick-change piece is provided between the through gauge and the through gauge mounting seat, a through gauge mounting hole is penetrated in the quick-change piece, at least one group of steel ball mounting holes are connected to the side wall of the through gauge mounting hole, one end of the steel ball mounting hole is communicated with the tapered hole, a steel ball is arranged in the steel ball mounting hole, a tapered hole is provided at the upper end of the through gauge mounting seat, the large end of the tapered hole faces the first motor, and the small end of the tapered hole faces the through gauge, the quick-change piece is inserted in the tapered hole, the large end of the tapered hole is communicated with a second spring mounting groove, a second spring is arranged in the second spring mounting groove, one end of the second spring is abutted and connected with the lower end of the quick-change piece, and the other end is abutted and connected with the bottom of the second spring mounting groove, the bottom of the second spring mounting groove is communicated with a second square hole, the lower end of the through gauge is provided with a second square column that can be adapted to the second square hole, the side wall of the tapered hole is communicated with a quick-release hole, the quick-release hole penetrates the through gauge mounting seat, and the quick-release hole is located at the end away from the tapered hole and connected with a limiting pin.

[0014] With the above technical solution, when disassembling, press the quick-change part downward, and the steel ball moves downward with the quick-change part until the steel ball approaches the large end of the tapered hole, so that the steel ball can move in the steel ball installation hole, and the steel ball is no longer in conflict with the through gauge, and the through gauge can be pulled out at this time. After the through gauge is pulled out, the quick-change part automatically resets upward under the action of the second spring. When installing, press the quick-change part downward again, and the steel ball moves downward with the quick-change part until the steel ball approaches the large end of the tapered hole, so that the steel ball can move in the steel ball installation hole, and the steel ball is no longer in conflict with the through gauge, and the through gauge is inserted until the second square column at the lower end of the through gauge is inserted into the second square hole, and the quick-change part is released. The second spring resets the quick-change part until the steel ball approaches the small end of the tapered hole, and the steel ball is squeezed to the side to conflict with the through gauge, so that the through gauge is stably installed on the through gauge mounting seat. Among them, the role of the second square column and the second square hole is to realize the synchronous rotation connection between the through gauge mounting seat and the through gauge. The shape of the "second square column and the second square hole" can be changed, as long as the synchronous rotation connection between the through gauge mounting seat and the through gauge can be realized. Furthermore, a blocking surface can be set at the upper end of the quick-change part to avoid excessive downward movement of the quick-change part when pressed down, thereby improving the flexibility of the quick-change operation. Furthermore, the limit pin is removed, and the conical hole is aligned with the quick-release hole. The steel ball can be installed from the quick-release hole. After the steel ball is installed, the limit pin can be installed back, which is convenient to operate.

[0015] The above-mentioned fully automatic filter threaded hole detection equipment can be further configured as follows: the guide assembly includes several groups of guide rods that are arranged in a direction parallel to the axis of the through gauge, the upper ends of the guide rods are connected to the positioning die seat by screws, and the frame is provided with a first linear bearing that is slidably connected to the guide rod, and the outer peripheral sleeve of the guide rod is provided with a third spring, the upper end of the third spring contacts the positioning die seat, and the lower end contacts the first linear bearing; the sensor is distributed below the guide rod, and a sheet metal part is connected below the frame by screws, and a strip hole is provided on the sheet metal part, and the sensor is inserted in the strip hole; the outer periphery of the rotating sleeve is linked with a positioning sleeve through a bearing, the positioning sleeve is distributed below the positioning hole and the positioning sleeve is connected to the frame by screws, and the lower end of the positioning sleeve is connected to several groups of connecting rods, and the lower end of the connecting rod is connected to a mounting flange plate, and the first motor is fixed to the mounting flange plate.

[0016] With the above technical solution, when the filter is qualified, the positioning die seat will drive the guide rod to move down to the preset position, which will be detected by the sensor and send out a signal that the product is qualified. During this process, the third spring is compressed. After the detection is completed, the filter is taken out and the third spring will automatically reset. At the same time, the first linear bearing is added to ensure the stability of the guide rod movement and prevent it from shaking left and right. For unqualified filters, although the positioning die seat will move down under the downward pressure of the filter, it will not drive the guide rod to the preset position, and the sensor will not send out a detection signal. In addition, the addition of sheet metal parts facilitates the installation of sensors, and strip holes are designed to adjust the sensor position according to actual conditions, thereby enhancing the adaptability of the detection mechanism to filters of different specifications and types.

[0017] The above-mentioned fully automatic filter thread hole detection device can be further set as follows: The feeding device includes a feeding conveyor belt assembly and a transfer conveyor belt assembly. A turntable rotatably installed on the frame is provided between the feeding conveyor belt assembly and the transfer conveyor belt assembly. A driving assembly capable of driving the turntable to rotate is linked in the middle of the turntable. A plurality of groups of clamping stations evenly spaced along the circumference are provided at the outer edge of the turntable, and a set of clamping plates is provided at each group of clamping stations; A sector-shaped feeding notch is provided on the side of the clamping plate away from the turntable; A plug-in member is provided between the clamping plate and the turntable, and the clamping plate and the turntable are both provided with plug-in holes adapted to the plug-in member. A plurality of groups of first magnetic members are also provided between the clamping plate and the turntable. A plurality of groups of second mounting holes are provided on the turntable or the clamping plate, and each group of first magnetic members is distributed in a group of second mounting holes; At least one electromagnet capable of fixing the filter at the sector-shaped feeding notch is provided at the sector-shaped feeding notch. A support plate is connected to the side of the electromagnet. A second magnetic member is provided on the side of the support plate away from the electromagnet. The second magnetic member is detachably connected to the support plate by screws, and the support plate is detachably connected to the electromagnet by screws. A first limiting hole and a second limiting hole recessed toward the inner side of the clamping plate are provided at the sector-shaped feeding notch. The lower end of the support plate is inserted into the first limiting hole until it contacts the end face of the turntable, and the electromagnet is inserted into the second limiting hole.

[0018] Adopting the above technical solution, first of all, the design of the plug-in member and the first magnetic member between the clamping plate and the turntable realizes the quick replacement of the clamping plate, enabling the feeding device to adapt to different specifications and types of filters, and greatly improving the production efficiency. The setting of the first magnetic member not only provides stable fixation for the clamping plate, but also further enhances the connection strength between the clamping plate and the turntable through its suction force, ensuring the stability of the clamping plate during the rotation of the turntable. Selecting the electromagnet as the main clamping component can quickly and stably adsorb the filter, ensuring the stability of the filter during transportation and reducing the shaking during transportation. The quick response performance of the electromagnet enables the filter to be quickly separated from the electromagnet when reaching a specific position, such as the visual inspection or waste removal area. In addition, the combined design of the support plate and the second magnetic member not only facilitates the installation and maintenance of the electromagnet, but also enhances the adsorption force of the electromagnet on the filter and improves the action response speed, which is crucial for improving the operation efficiency and reliability of the overall device. The design of the sector-shaped feeding notch optimizes the feeding stability of the filter, better fits the shape of the filter, and further improves the accuracy and safety of the feeding process.

[0019] The above-mentioned fully automatic filter thread hole detection device can be further set as follows: the transfer conveyor belt assembly includes a transfer conveyor belt, and pulley wheels are distributed and linked at both ends of the transfer conveyor belt. A group of pulley wheels is linked to a second motor; a support frame is arranged between the two groups of pulley wheels, the transfer conveyor belt is sleeved on the outer periphery of the support frame, and several groups of third magnetic parts are arranged between the support frame and the transfer conveyor belt. Several groups of third magnetic parts are all fixed on the support frame by screws, and several groups of third magnetic parts are arranged in sequence along the direction parallel to the transfer conveyor belt.

[0020] With the above technical solution, after the filter is moved from the turntable to the transfer conveyor belt, the third magnetic part will generate a suction force on the filter, so that the filter will not sway left and right during the process of moving with the transfer conveyor belt, and the position of the filter will not change easily, which is convenient for subsequent clamping of the filter. It should be noted that although the third magnetic part does not move with the transfer conveyor belt, the way it generates a suction force on the filter will not affect the forward movement of the transfer conveyor belt, and the transfer conveyor belt can work normally. At the same time, the separate design of the third magnetic part and the transfer conveyor belt facilitates the disassembly and assembly of the third magnetic part. Further, by controlling the rotation speed of the servo motor, the distance between every two adjacent filters can be kept consistent, that is, equal-distance feeding, so as to facilitate the clamping mechanism to accurately clamp several groups of filters at the same time.

[0021] The above-mentioned fully automatic filter thread hole detection device can be further set as follows: feeding stations, detection stations, transfer stations, and waste discharge stations are sequentially arranged along the circumferential direction on the outer periphery of the turntable; the feeding conveyor belt assembly corresponds to the feeding station, and the transfer conveyor belt assembly corresponds to the transfer station; a end face detection component and a height sensor are arranged at the detection station, and an end face detection hole is arranged on the frame corresponding to the detection station, and the end face detection hole is distributed above the end face detection component; the height sensor is connected with an adjusting plate by screws, the adjusting plate is slidably connected with a slider, the slider is fixed on the frame, a hand wheel is arranged on one side of the adjusting plate, and a threaded hole is arranged on the frame corresponding to the hand wheel; a first waste discharge frame is arranged at the waste discharge station, and the first waste discharge frame is connected with the frame by a hinge.

[0022] An improved technical solution is adopted. By setting a feeding station, an inspection station, a transfer station, and a waste discharging station on the turntable, the whole process automation of the filter from feeding to discharging is realized, significantly improving the production efficiency and product quality. At the feeding station, the feeding conveyor belt assembly accurately conveys the filter to the clamping plate of the turntable, and then the turntable transfers the filter to different stations in sequence for subsequent operations. At the inspection station, the end face inspection component and the height sensor work together to accurately detect the lower end face and height of the filter. The end face inspection component can detect whether the threaded holes exist and whether the number of connecting holes on its outer periphery is correct, ensuring that the filter meets the production standards. At the same time, the end face inspection component can select technologies such as cameras to further ensure the accuracy and efficiency of the inspection. The height sensor is slidably connected to the frame through an adjusting plate and a slider, and is precisely fixed by a handwheel and a threaded hole to ensure that the sensor detects the height of the filter at the correct position and guarantees that the product height meets the requirements. The transfer station transports the qualified filters to the next working step in an orderly manner, while the unqualified products are removed at the waste discharging station. During this process, the electromagnet plays a key role. For unqualified filters, when passing through the transfer conveyor belt, the electromagnet maintains the suction force and does not release, accurately transferring the unqualified products to the first waste discharging frame, and then releasing the electromagnet, so that the unqualified filters automatically fall into the first waste discharging frame, realizing the automatic exclusion of unqualified products.

[0023] The above-mentioned full-automatic filter threaded hole detection equipment can be further set as follows: The clamping device includes a transverse guide rail arranged above the frame, a clamping frame movable on the transverse guide rail, at least one set of clamping plate mechanisms arranged on the clamping frame, a transverse driving component for driving the clamping plate mechanism to reciprocate along the axis direction of the transverse guide rail, and a longitudinal driving component for driving the clamping plate mechanism to lift along the axial direction of the clamping frame; The clamping plate mechanism includes a main clamp, a sub-clamp, and a clamp driving component for driving the relative displacement of the main clamp and the sub-clamp. A number of corresponding V-shaped clamping openings are provided on both the main clamp and the sub-clamp. The corresponding V-shaped clamping openings between the main clamp and the sub-clamp form a quadrilateral clamping position for clamping the filter. A set of floating clamping blocks is arranged at each V-shaped clamping opening of the main clamp. The floating clamping blocks are linked with a fourth spring at one end away from the clamping position. The main clamp is provided with a third mounting hole corresponding to each clamping position. The third mounting hole is open at one end facing the floating clamping block and blocked at the other end. The fourth spring is inserted into the third mounting hole and one end of the spring is connected to the floating clamping block; A set of guide rods are distributed and connected on both sides of the floating clamping block. The main clamp is provided with guide holes. The guide holes are distributed on one side of the third mounting hole and are parallel to each other. The guide rods are inserted into the guide holes, and a second linear bearing is sleeved on the outer periphery of the guide rods, and the second linear bearing is limited in the guide holes.

[0024] With the above technical solution, a set of floating clamping blocks is arranged on the main fixture corresponding to each clamping position, and the floating clamping blocks are connected by the fourth spring and the guide rod, so that each clamping position can adaptively adjust the clamping force according to actual needs, ensuring the uniformity of the clamping force and the best elastic change state. Thus, the risk of displacement or tipping of the filter during clamping due to loosening of some clamping mouths is avoided, and at the same time, the risk of deformation of the filter due to excessive tightness of some clamping mouths during clamping is also avoided. Among them, the design of one end of the third mounting hole being open and the other end being closed facilitates the connection and elastic expansion and contraction of the fourth spring, enabling the floating clamping block to adjust its position according to needs and obtain the best elastic clamping force. At the same time, the floating clamping block is connected to the guide hole of the main fixture through the guide rod, achieving precise control of the movement direction of the floating clamping block and ensuring the smoothness and response speed of the movement of the floating clamping block. The sleeving of the second linear bearing reduces the friction between the guide rod and the guide hole, further improving the smoothness of the movement and the durability of the device.

[0025] The above-mentioned fully automatic filter thread hole detection device can be further set as follows: A set of pulling cylinders are respectively arranged in the middle of the main fixture and the sub-fixture. A connecting bolt is arranged between the two sets of pulling cylinders. The two ends of the connecting bolt are respectively threadedly connected to the output ends of a set of pulling cylinders. The bodies of the pulling cylinders are respectively connected with a support plate by screws, and the support plate is connected to the main fixture or the sub-fixture by screws; A wire pressing buckle is arranged on the main fixture or the sub-fixture. One end of the wire pressing buckle is connected to the main fixture or the sub-fixture by screws, and an arc-shaped wire groove is arranged in the middle of the wire pressing buckle.

[0026] With the above technical solution, the output ends (i.e., the piston rods of the cylinders) of the two sets of pulling cylinders are relatively fixed through the connecting bolt. The output end (i.e., the piston rod of the cylinder) of each set of cylinders moves relative to its own cylinder body, so as to realize the approach and separation of the two sets of pulling cylinders. The two pulling cylinders pull against each other, playing the role of assisting the main fixture and the sub-fixture on both sides and improving the clamping stability. Further setting the wire pressing buckle and arranging an arc-shaped wire groove in the middle can clamp wire harnesses, air pipes, etc. One end of the wire pressing buckle is fixed with screws, and the other end can stably clamp wire harnesses, air pipes, etc. by using its own structural form, and at the same time, it is convenient to disassemble and remove wire harnesses, air pipes, etc.

[0027] The above-mentioned fully automatic filter thread hole detection device can be further set as follows: The discharging and transporting component includes a discharging conveyor belt. The two ends of the discharging conveyor belt are linked with a sprocket transmission group, and the sprocket transmission group is linked with a third motor; The discharging and transporting component also includes a second waste discharging frame and a pushing plate. The second waste discharging frame and the pushing plate are respectively arranged on both sides of the discharging conveyor belt, and the second waste discharging frame and the pushing plate are distributed oppositely. The pushing plate is linked with a cylinder, and the cylinder is fixed on the frame.

[0028] With the above technical solution, the discharging conveyor belt can not only transport qualified filters but also remove unqualified filters. For the filters detected by the testing agency, the sensors in the testing agency will send signals. According to the positions of the sensors that do not detect the guide rods (unqualified filters), counting is carried out in sequence, and the pushing plate pushes the corresponding filters to the second waste bin for removal according to the unqualified positions. The qualified filters can be discharged following the discharging conveyor belt, realizing full-automatic detection and waste removal.

Detailed implementation manners

[0054] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0055] As Figures 1 to 23 shown in the full-automatic filter thread hole detection device, which includes a frame. A plurality of groups of thread detection holes are provided on the frame. Feeding device a and discharging and transporting component d are respectively provided on both sides of the plurality of groups of thread detection holes. A clamping device c is provided above the plurality of groups of thread hole detection holes. A set of detection mechanism b is respectively provided in each group of thread detection holes.

[0056] The feeding device a includes a feeding conveyor belt assembly and a transfer conveyor belt assembly b. A turntable 1a rotatably installed on the frame is provided between the feeding conveyor belt assembly and the transfer conveyor belt assembly b. A driving component capable of driving the turntable 1a to rotate is linked in the middle of the turntable 1a.

[0057] Four sets of clamping stations evenly spaced in the circumferential direction are provided on the outer edge of the turntable 1a. A set of clamping plates 2a is provided at each clamping station. A fan-shaped feeding notch 3a is provided on the side of the clamping plate 2a away from the turntable 1a. The fan-shaped feeding notch 3a fits the shape of the filter more closely, and the feeding is more stable.

[0058] A plug-in member 4a is provided between the clamping plate 2a and the turntable 1a. The clamping plate 2a and the turntable 1a are both provided with plug-in holes adapted to the plug-in member 4a. The plug-in member 4a can adopt standard parts such as pins and screws, as long as the shaft-hole matching relationship with the plug-in hole can be realized. Four sets of first magnetic members 5a are also provided between the clamping plate 2a and the turntable 1a. Four sets of second mounting holes 6a are provided on the turntable 1a or the clamping plate 2a. Each set of first magnetic members 5a is distributed in a set of second mounting holes 6a. After the first magnetic member 5a is placed in the second mounting hole 6a, a suction force will be generated on the clamping plate 2a, further limiting the clamping plate 2a. Under the combined action of the first magnetic member 5a and the plug-in member 4a, the clamping plate 2a can be stably connected to the turntable 1a. Moreover, the disassembly and installation of the clamping plate 2a are very convenient. Take out the plug-in member 4a and pull out the clamping plate 2a to separate the clamping plate 2a from the turntable 1a. During installation, only need to place the clamping plate 2a at the clamping station, and then insert the plug-in member 4a into the plug-in hole. Using the suction force of the four sets of first magnetic members 5a on the clamping plate 2a, the installation of the clamping plate 2a is completed. The sizes of the fan-shaped feeding notches 3a on different clamping plates 2a are different, which can adapt to different specifications and types of filters, that is, the adaptability of the automatic feeding device designed in this application is relatively high.

[0059] At the fan-shaped feeding notch 3a, there are 2 sets of electromagnets 7a that can fix the filter at the fan-shaped feeding notch 3a. A support plate 8a is connected to the side of the electromagnet 7a. A second magnetic member 9a is provided on the side of the support plate 8a away from the electromagnet 7a. The second magnetic member 9a is detachably connected to the support plate 8a by screws, and the support plate 8a is detachably connected to the electromagnet 7a by screws. At the fan-shaped feeding notch 3a, there are a first limiting hole 10a and a second limiting hole 11a that are recessed towards the inner side of the clamping plate 2a. The lower end of the support plate 8a is inserted into the first limiting hole 10a until it contacts the end face of the turntable 1a, and the electromagnet 7a is inserted into the second limiting hole 11a. Selecting the electromagnet 7a as the main clamping component can quickly and stably suck the filter. At the same time, when it reaches a predetermined position (such as visual inspection or waste removal or feeding position), it can quickly separate from the filter. The "clamping method" is stable and the work is reliable, and the filter will not shake during transportation. The support plate 8a is used to install the electromagnet 7a; designing the second limiting hole 11a makes the electromagnet 7a closer to the filter after being installed on the clamping plate 2a; then by designing the first limiting hole 10a, it is convenient for the positioning of the support plate 8a; further adding the second magnetic member 9a can enhance the magnetic force, so that the electromagnet 7a can maintain a strong adsorption force even in a low-power state. At the same time, the enhanced magnetic force can make the moving iron core in the electromagnet 7a move more quickly, reduce the action time, and improve the response speed of the electromagnet 7a.

[0060] The driving component includes a transmission shaft 12a. The upper end of the transmission shaft 12a is linked to the middle of the turntable 1a, and the lower end is linked to a third motor 13a. A wire harness hole 15a is provided in the transmission shaft 12a and runs through along the axis direction. The electromagnet 7a is connected to a slip ring 14a through a wire. The slip rings 14a are distributed below the third motor 13a, and the wire passes through the wire harness hole 15a to connect the electromagnet 7a and the slip ring 14a. The third motor 13a can drive the transmission shaft 12a to rotate through a divider, realizing the rotation of the turntable 1a. A wire harness hole 15a is provided in the transmission shaft 12a for collecting wire harnesses. After the wire harness passes through the wire harness hole 15a, each electromagnet 7a is connected to the slip ring 14a to realize the on-off control of the electromagnet 7a.

[0061] On the outer periphery of the turntable 1a, there are successively arranged a feeding station, an inspection station, a transfer station, and a waste removal station in the circumferential direction.

[0062] The feeding conveyor belt assembly corresponds to the loading station. The feeding conveyor belt assembly includes a feeding conveyor belt 16a. Chain sprocket wheels 17a are linked to both ends of the feeding conveyor belt 16a. A set of rollers 18a are arranged between the two sets of chain sprocket wheels 17a. The rollers 18a are distributed below the feeding conveyor belt 16a and are in rolling connection with each other. Both ends of the chain sprocket wheels 17a and both ends of the rollers 18a are connected to the machine frame through bearings. A driving source capable of driving the chain sprocket wheels 17a to rotate is linked to a set of chain sprocket wheels 17a. By setting the feeding conveyor belt 16a, it can be operated manually or in combination with a fully automatic production line. The filter reaches the feeding conveyor belt 16a and is pulled by the feeding conveyor belt 16a onto the turntable 1a until it enters the clamping station and is sent to the next station by the electromagnet 7a. Among them, the chain sprocket wheels 17a can be driven by a motor or the like to drive the feeding conveyor belt 16a to rotate. By arranging a set of rollers 18a between the two sets of chain sprocket wheels 17a, the working stability of the feeding conveyor belt 16a is improved.

[0063] At the inspection station, there are an end face inspection component 19a and a height sensor 20a. The machine frame is provided with an end face inspection hole 21a corresponding to the inspection station, and the end face inspection hole 21a is distributed above the end face inspection component 19a. The end face inspection component 19a is used to inspect the lower end face of the filter, such as whether there are threaded holes and whether the number of connecting holes around the threaded hole is correct. Qualified products are driven by the turntable 1a to the next station for the next step of work, and unqualified products are removed. Among them, the end face inspection component 19a can be a camera or the like.

[0064] The height sensor 20a is connected with an adjusting plate 22a through screws. The adjusting plate 22a is slidably connected with a slider 24a, and the slider 24a is fixed on the machine frame. A handwheel 23a is arranged on one side of the adjusting plate 22a, and the machine frame is provided with a threaded hole corresponding to the handwheel 23a. The height sensor 20a can detect the height of the filter. Qualified products are driven by the turntable 1a to the next station for the next step of work, and unqualified products are removed. Among them, the height of the adjusting plate 22a is adjusted through a slide plate until the height sensor 20a reaches the correct height. Then, the handwheel 23a is rotated until the end of the handwheel 23a abuts against the adjusting plate 22a, so as to fix the adjusting plate 22a, that is, the height sensor 20a remains stationary, which is convenient for subsequent height detection.

[0065] The transfer conveyor belt assembly f corresponds to the transfer station. The transfer conveyor belt assembly f includes a transfer conveyor belt f1. At both ends of the transfer conveyor belt f1, pulleys f2 are distributed and linked. A set of pulleys f2 is linked to a second motor f5. Between the two sets of pulleys f2, there is a support frame f3. The transfer conveyor belt f1 is sleeved on the outer periphery of the support frame f3. Between the support frame f3 and the transfer conveyor belt f1, there are multiple sets of third magnetic parts f4. The multiple sets of third magnetic parts f4 are all fixed to the support frame f3 by screws, and the multiple sets of third magnetic parts f4 are arranged in sequence along the direction parallel to the transfer conveyor belt f1. After the filter is moved from the turntable 1a to the transfer conveyor belt f1, the third magnetic part f4 will generate a suction force on the filter, so that the filter will not sway left and right during the process of moving with the transfer conveyor belt f1, and the position of the filter will not change easily, which is convenient for subsequent clamping of the filter. It should be noted that although the third magnetic part f4 does not move along with the transfer conveyor belt f1, the way it generates a suction force on the filter will not affect the forward movement of the transfer conveyor belt f1, and the transfer conveyor belt f1 can maintain normal operation. At the same time, separating the third magnetic part f4 from the transfer conveyor belt f1 is convenient for the disassembly and assembly of the third magnetic part f4.

[0066] At the waste discharging station, there is a first waste discharging frame 25a. The first waste discharging frame 25a is connected to the machine frame through a hinge. The unqualified filters are collected. When the unqualified filters pass through the transfer conveyor belt f1, the electromagnet 7a continues to maintain the suction force and does not release. The turntable 1a drives the unqualified filters to the first waste discharging frame 25a and then releases them, and the unqualified filters will automatically fall into the first waste discharging frame 25a.

[0067] Working principle of feeding device a: the feed conveyor belt assembly transports the filter to the turntable 1a, the filter enters the clamping station in sequence, and two sets of electromagnets 7a suck the filter. It rotates with the turntable 1a to the end face detection component 19a for detection. The frame is provided with an end face detection hole 21a. The end face detection component 19a can detect the lower end face of the filter through the end face detection hole 21a. It is mainly used to detect whether the threaded hole of the filter exists and whether the number of connecting holes around the threaded hole is correct. The filter will continue to rotate with the turntable 1a to the bottom of the height sensor 20a. The height sensor 20a further detects whether the height of the filter is qualified. After two tests, the tested filters will continue to rotate with the turntable 1a. Qualified products (i.e., the height, threaded holes, and the number of connection holes around the threaded holes are all correct) will be transported to the transfer conveyor belt assembly b after the height detection, and the two sets of electromagnets 7a will stop working, release the filter, and the transfer conveyor belt f1 will drive the filter to move. Unqualified products (i.e., the height, threaded holes, and the number of connection holes around the threaded holes are incorrect) will continue to rotate with the turntable 1a until they move to the first row of waste frames 25a, where the two sets of electromagnets 7a will stop working, release the filter, and the filter will fall into the first row of waste frames 25a.

[0068] The feeding device a can not only realize orderly feeding, but also realize the rapid replacement of the clamping plate 2a to adapt to filters of different specifications and types. At the same time, it can also perform various tests on the filter and remove waste. Furthermore, the filter can be transported stably, and the filter will not deflect left or right during the transportation process. "

[0069] The detection mechanism b includes a positioning die base 1b and a first motor 2b. A through gauge mounting seat 3b is provided between the first motor 2b and the positioning die base 1b. A through gauge 4b ​​is connected to the top of the through gauge mounting seat 3b. A detection clearance hole 5b through which the through gauge 4b ​​can pass runs through the middle of the positioning die base 1b. The positioning die base 1b is linked with a guide component. A rotating sleeve 6b is provided between the through gauge mounting seat 3b and the first motor 2b. The lower end of the rotating sleeve 6b is linked with the output end of the first motor 2b. A linkage structure is provided between the rotating sleeve 6b and the through gauge mounting seat 3b. The linkage structure includes a first square column 7b arranged at the lower end of the through gauge mounting seat 3b. A first square hole 8b adapted to the first square column 7b is provided in the rotating sleeve 6b. The through gauge mounting seat 3b is linked with a first spring 9b. Through the first square column 7b and the first square hole 8b, the synchronous rotation connection between the gauge mounting seat 3b and the rotating sleeve 6b can be achieved, that is, the first motor 2b drives the rotating sleeve 6b to rotate, so the first square hole 8b and the first square column 7b can also be transformed into other shapes, as long as the synchronous rotation connection between the gauge mounting seat and the rotating sleeve 6b can be achieved.

[0070] The rotating sleeve 6b drives the go - gauge mounting seat 3b to rotate, and the go - gauge 4b follows the rotation of the go - gauge mounting seat 3b to detect the threaded holes of the filter. By designing the first spring 9b, the go - gauge 4b can float up and down. Under the downward pressing force of the filter, the go - gauge 4b and the go - gauge mounting seat 3b move downward relative to the rotating sleeve 6b, so as to facilitate the go - gauge 4b to detect the threaded holes of the filter. When the detected filter is unqualified, the go - gauge 4b will not get stuck with the filter, and the filter will not spin around.

[0071] On the upper part of the go - gauge mounting seat 3b, there is an annular flange strip 10b protruding towards the outside. At the upper end of the rotating sleeve 6b, there is a first spring mounting groove 11b. The first spring 9b is sleeved in the first spring mounting groove 11b and the first spring 9b is sleeved on the outer periphery of the go - gauge mounting seat 3b. The upper end of the first spring 9b contacts the annular flange strip 10b, and the lower end contacts the bottom of the first spring mounting groove 11b. Designing the annular flange strip 10b and the first spring mounting groove 11b provides a good working environment for the first spring 9b, enabling the first spring 9b to expand and contract stably, and enabling the go - gauge 4b to float up and down.

[0072] At the upper end of the rotating sleeve 6b, there is an upper flange seat 12b connected by screws. In the middle of the upper flange seat 12b, there is a first mounting hole 13b. The first mounting hole 13b is sleeved on the outer periphery of the go - gauge mounting seat 3b and the first mounting hole 13b is distributed above the annular flange strip 10b. The inner diameter of the first mounting hole 13b is smaller than the outer diameter of the annular flange strip 10b. The upper flange seat 12b is connected to the rotating sleeve 6b by screws, which is convenient for the installation and disassembly of the first spring 9b. Designing the first mounting hole 13b can prevent interference between the go - gauge mounting seat 3b and the upper flange seat 12b when the go - gauge mounting seat 3b floats up and down. The purpose of "the inner diameter of the first mounting hole 13b is smaller than the outer diameter of the annular flange strip 10b" is to limit the annular flange strip 10b and prevent the go - gauge 4b and the go - gauge mounting seat 3b from rising and falling excessively.

[0073] At the lower end of the rotating sleeve 6b, there is a lower flange seat 14b connected by screws. The first square hole 8b is arranged at the upper end of the lower flange seat 14b. At the lower end of the lower flange seat 14b, there is a connecting shaft 15b. The connecting shaft 15b is linked with a coupling 16b, and the coupling 16b is linked with the output end of the first motor 2b. Arranging the first square hole 8b at the upper end of the lower flange seat 14b is more convenient for processing compared with arranging the first square hole 8b inside the rotating sleeve 6b. Adding the coupling 16b and linking the rotating sleeve 6b with the first motor 2b through the connecting shaft 15b at the lower end of the lower flange seat 14b can effectively transmit torque and motion, reduce the vibration and impact of the mechanical transmission system at the same time, have the ability to compensate for the offset of the two shafts, and improve the dynamic performance and service life of the first motor 2b, the rotating sleeve 6b, etc.

[0074] A quick-change part 17b is provided between the go gauge 4b and the go gauge mounting seat 3b. A go gauge mounting hole 18b runs through the quick-change part 17b. Three groups of steel ball mounting holes 19b communicate with the side wall of the go gauge mounting hole 18b. One end of the steel ball mounting hole 19b communicates with a tapered hole 20b. A steel ball 21b is arranged in the steel ball mounting hole 19b. A tapered hole 20b is provided at the upper end of the go gauge mounting seat 3b. The large end of the tapered hole 20b faces the first motor 2b, and the small end of the tapered hole 20b faces the go gauge 4b. The quick-change part 17b is inserted into the tapered hole 20b. The large end of the tapered hole 20b communicates with a second spring mounting groove 22b. A second spring 23b is arranged in the second spring mounting groove 22b. One end of the second spring 23b is in contact connection with the lower end of the quick-change part 17b, and the other end is in contact connection with the bottom of the second spring mounting groove 22b. The bottom of the second spring mounting groove 22b communicates with a second square hole 24b. The lower end of the go gauge 4b is provided with a second square post 25b that can be adapted to the second square hole 24b. During disassembly, the quick-change part 17b is pressed downward, and the steel ball 21b moves downward along with the quick-change part 17b until the steel ball 21b approaches the large end of the tapered hole 20b, so that the steel ball 21b can move in the steel ball mounting hole 19b, and the steel ball 21b is no longer in a contact relationship with the go gauge 4b. At this time, the go gauge 4b can be pulled out. After the go gauge 4b is pulled out, the quick-change part 17b automatically resets upward under the action of the second spring 23b. During installation, the quick-change part 17b is pressed downward again, and the steel ball 21b moves downward along with the quick-change part 17b until the steel ball 21b approaches the large end of the tapered hole 20b, so that the steel ball 21b can move in the steel ball mounting hole 19b, and the steel ball 21b is no longer in a contact relationship with the go gauge 4b. The go gauge 4b is placed until the second square post 25b at the lower end of the go gauge 4b is inserted into the second square hole 24b. The quick-change part 17b is released, and the second spring 23b resets the quick-change part 17b until the steel ball 21b approaches the small end of the tapered hole 20b, and the steel ball 21b is squeezed to the side to contact the go gauge 4b, realizing the stable installation of the go gauge 4b on the go gauge mounting seat 3b. Among them, the functions of the second square post 25b and the second square hole 24b are to realize the synchronous rotation connection between the go gauge mounting seat 3b and the go gauge 4b. The shapes of the "second square post 25b and the second square hole 24b" can be changed as long as the synchronous rotation connection between the go gauge mounting seat 3b and the go gauge 4b can be realized. Further, a stop surface can be provided at the upper end of the quick-change part 17b to prevent the excessive downward movement of the quick-change part 17b during downward pressing and improve the flexibility of the quick-change operation.

[0075] A quick-installation hole 34b communicates with the side wall of the tapered hole 20b. The quick-installation hole 34b runs through the go gauge mounting seat 3b, and a limit pin 35b is connected to the end of the quick-installation hole 34b far from the tapered hole 20b. The limit pin 35b is taken out, the tapered hole 20b is aligned with the quick-installation hole 34b, and the steel ball 21b can be installed from the quick-installation hole 34b. After the steel ball 21b is installed, the limit pin 35b is installed back, and the operation is convenient.

[0076] The guiding assembly includes three groups of guide rods 36b all arranged along the direction parallel to the axis of the go - gauge 4b. The upper ends of the guide rods 36b are connected to the positioning die base 1b by screws. On the frame, there is a first linear bearing 37b slidably connected to the guide rods 36b. A third spring 26b is sleeved on the outer periphery of the guide rods 36b. The upper end of the third spring 26b contacts the positioning die base 1b, and the lower end contacts the first linear bearing 37b. When the filter is a qualified product, the positioning die base 1b will drive the guide rods 36b to move downward to a preset position. During this process, the third spring 26b will be compressed. After the detection is completed and the filter is taken out, the third spring 26b will drive the guide rods 36b to automatically reset. The addition of the first linear bearing 37b improves the moving stability of the guide rods 36b and prevents them from shaking left and right. When the filter is a non - qualified product, the positioning die base 1b will move downward under the pressing force of the filter, but it will not drive the guide rods 36b to move to the preset position. Once the filter is taken out, the third spring 26b will drive the guide rods 36b to automatically reset.

[0077] Below the guide rods 36b, there is a sensor 27b. Below the frame, there is a sheet metal part 28b connected by screws. On the sheet metal part 28b, there is a strip - shaped hole 29b, and the sensor 27b is inserted at the strip - shaped hole 29b. By setting the sensor 27b, when the filter is a qualified product, the positioning die base 1b will drive the guide rods 36b to move downward to the preset position. Once the sensor 27b detects the guide rods 36b, it will send out a signal indicating that the product is qualified. When the filter is a non - qualified product, the positioning die base 1b will move downward under the pressing force of the filter, but it will not drive the guide rods 36b to move to the preset position. At this time, the sensor 27b will not detect the guide rods 36b. Further, the addition of the sheet metal part 28b facilitates the installation of the sensor 27b, and the design of the strip - shaped hole 29b can adjust the position of the sensor 27b according to the actual situation, expanding the adaptability of the detection mechanism and enabling it to be applied to the detection of filters of different specifications and types.

[0078] For each group of rotating sleeves 6b, the frame is provided with a group of positioning holes 30b. The positioning holes 30b are in clearance fit with the rotating sleeves 6b. The outer periphery of the rotating sleeves 6b is linked with a positioning sleeve 31b through a bearing. The positioning sleeves 31b are distributed below the positioning holes 30b and the positioning sleeves 31b are connected to the frame by screws. The lower ends of the positioning sleeves 31b are connected with three groups of connecting rods 32b, and the lower ends of the connecting rods 32b are connected with mounting flange plates 33b. The first motor 2b is fixed on the mounting flange plates 33b. By setting the positioning holes 30b, interference between the rotating sleeves 6b and the frame during rotation is avoided. The addition of the positioning sleeves 31b, connecting rods 32b, and mounting flange plates 33b, on the one hand, realizes the fixed installation of the first motor 2b, and on the other hand, the rotating sleeves 6b and the positioning sleeves 31b are linked through a bearing to guide the rotating sleeves 6b and improve the working stability of the rotating sleeves 6b.

[0079] The working principle of the testing mechanism b is as follows:

[0080] The clamping device c places the filter on the go - gauge mounting base 3b, and then presses down the filter so that the go - gauge 4b can contact the threaded hole and detect the threaded hole. During this process, according to the pressing - down distance of the filter, the go - gauge 4b and the go - gauge mounting base 3b will move downward under the action of the linkage structure. Next, the first motor 2b drives the rotating sleeve 6b to rotate, the rotating sleeve 6b drives the go - gauge mounting base 3b to rotate through the linkage structure, and the go - gauge mounting base 3b drives the go - gauge 4b to rotate. It should be noted that the purpose of "pressing down the filter" is to facilitate the go - gauge 4b to contact the threaded hole and more smoothly detect the threaded hole of the filter.

[0081] If the filter is qualified, the go - gauge 4b is thread - connected to the threaded hole, and the go - gauge 4b will drive the filter to gradually move downward until a preset position. During this process, the positioning die base 1b will drive the guide rod 36b to move downward to the preset position. Once the sensor 27b detects the guide rod 36b, it will send out a signal indicating that the product is qualified.

[0082] If the filter is unqualified, the go - gauge 4b cannot be thread - connected to the threaded hole. Due to the design of the linkage structure, the go - gauge 4b and the go - gauge mounting base 3b will gradually move downward following the filter. The contact relationship between the go - gauge 4b and the filter is a flexible one, rather than the mutual impact relationship in the prior art, thus avoiding the phenomenon of the go - gauge 4b being stuck with the filter. And because the filter is unqualified, the go - gauge 4b will not be connected to the threaded hole, so the unqualified filter will not move downward a long distance. Although the positioning die base 1b will move downward under the pressing action of the filter, it will not drive the guide rod 36b to move to the preset position. At this time, the sensor 27b will not detect the guide rod 36b. Therefore, even if an unqualified filter is detected, it will not affect the detection of other qualified filters. During this process, the first motor 2b still rotates normally, and the situation of the first motor 2b being overloaded is also avoided.

[0083] In summary, the testing mechanism b has the following advantages:

[0084] Firstly, it can not only achieve the thread detection of the filter, but also during the process of detecting the filter, the go - gauge 4b will float up and down under the action of the linkage structure to avoid the situation of an unqualified filter spinning, and at the same time avoid the phenomenon of the filter being stuck with the go - gauge 4b. In this way, the go - gauge mounting base 3b does not need to overcome the force of the plunger screw, reducing the wear of the plunger screw, the first motor 2b, the go - gauge 4b, the threaded hole of the filter, etc. The first motor 2b can rotate continuously without overloading, and the guiding components are evenly stressed. It reduces the later maintenance cost and extends the service life of this thread - testing mechanism.

[0085] Second, since the unqualified filter element will not rotate and will not get stuck with the go - gauge 4b, there is no need to immediately remove the unqualified product manually. Instead, it can wait until the single - detection operation is completed, and then remove the unqualified filter element, reducing the workload of workers and improving the safety of the working environment.

[0086] Third, by setting up the quick - change parts 17b, steel balls 21b, second springs 23b, tapered holes 20b, etc., the quick - change of the go - gauge 4b can be realized to adapt to the detection of filter elements of different specifications and types, improving the adaptability of this embodiment.

[0087] The clamping device c includes a transverse guide rail c20 arranged above the frame, a clamping frame c21 movable on the transverse guide rail c20, two groups of clamping plate mechanisms c22 arranged on the clamping frame c21, a transverse driving assembly for driving the clamping plate mechanism c22 to reciprocate along the axis direction of the transverse guide rail c20, and a longitudinal driving assembly for driving the clamping plate mechanism c22 to lift along the axial direction of the clamping frame c21.

[0088] The transverse driving assembly includes transverse synchronous wheels arranged on both sides of the transverse guide rail c20, a transverse synchronous belt c23 wound around the transverse synchronous wheels on both sides, a transverse driving motor c24 arranged on one side of the transverse guide rail c20 to drive one of the transverse synchronous wheels to rotate, and a transverse fixing block c25 arranged on the clamping frame c21 and connected to the transverse synchronous belt c23. The transverse driving motor c24 drives the transverse synchronous belt c23 to rotate, thereby driving the clamping frame c21 to reciprocate back and forth along the transverse guide rail c20. The longitudinal driving assembly includes longitudinal synchronous wheels c26 arranged on both sides of the clamping frame c21, a longitudinal synchronous belt c27 sleeved between the longitudinal synchronous wheels c26, longitudinal lifting plates c28 arranged at both ends of the clamping plate mechanism c22, and a longitudinal driving motor arranged on the clamping frame c21 to drive the longitudinal synchronous wheels c26 to rotate. A longitudinal driving screw c29 is arranged between the longitudinal synchronous wheel c26 and the longitudinal lifting plate c28. A longitudinal screw sleeve c30 is arranged on the longitudinal lifting plate c28. One end of the longitudinal driving screw c29 is linked with the longitudinal synchronous wheel c26, and the longitudinal driving screw c29 is in threaded connection with the longitudinal screw sleeve c30. The longitudinal driving motor drives the longitudinal synchronous wheel c26 to rotate, causing the clamping plate mechanism c22 to lift along the axial direction of the longitudinal driving screw c29.

[0089] Each group of clamping plate mechanisms c22 includes a main clamp 1c, a sub - clamp 2c, and a clamp driving component for driving the relative displacement of the main clamp 1c and the sub - clamp 2c. A plurality of corresponding clamping openings are arranged on both the main clamp 1c and the sub - clamp 2c. The corresponding clamping openings between the main clamp 1c and the sub - clamp 2c form a clamping position for clamping the filter element.

[0090] A set of floating clamping blocks 3c is provided at each clamping opening of the main fixture 1c. An elastic tensioning assembly is linked to the floating clamping block 3c at the end away from the clamping position, and the elastic tensioning assembly is linked to the main fixture 1c.

[0091] The elastic tensioning assembly includes a fourth spring 4c. A set of third mounting holes 5c is provided at each clamping opening of the main fixture 1c. The third mounting holes 5c are open at the end facing the floating clamping block 3c and blocked at the other end. The fourth spring 4c is inserted into the third mounting hole 5c and one end of the fourth spring 4c is connected to the floating clamping block 3c. The third mounting hole 5c is set to be open at one end and closed at the other end for the purpose of facilitating one end of the fourth spring 4c to extend out from the opening and be connected to the floating clamping block 3c, while the other end of the fourth spring 4c is limited at the closed end. In this way, the fourth spring 4c can undergo elastic expansion and contraction to adapt to the position change of the floating clamping block 3c, so that the floating clamping block 3c can obtain the optimal elastic clamping force.

[0092] The elastic tensioning assembly further includes two sets of guide rods 6c. One end of each set of guide rods 6c is connected to the floating clamping block 3c. Guide holes 7c are provided on the main fixture 1c. The guide holes 7c are distributed on one side of the third mounting hole 5c and are parallel to each other. The guide rods 6c are inserted into the guide holes 7c. A second linear bearing 8c is sleeved on the outer periphery of the guide rod 6c. The second linear bearing 8c is limited in the guide hole 7c. The floating clamping block 3c can drive the guide rod 6c to reciprocate along the axis of the guide hole 7c. By connecting the guide rods 6c to the floating clamping block 3c and inserting these guide rods 6c into the guide holes 7c on the main fixture 1c, the precise control of the movement direction of the floating clamping block 3c is realized, ensuring that the floating clamping block 3c can stably reciprocate along the established direction, so that the clamping force is more uniform and controllable. Further, by sleeving the second linear bearing 8c on the outer periphery of the guide rod 6c and limiting the second linear bearing 8c in the guide hole 7c, the friction between the guide rod 6c and the guide hole 7c is effectively reduced, and the smoothness and response speed of the movement of the floating clamping block 3c are improved.

[0093] The two ends of the guiding hole 7c are open. A limiting retaining ring 9c is provided at the other end of the guiding rod 6c. The outer diameter of the limiting retaining ring 9c is larger than the outer diameter of the upper opening of the guiding hole 7c. By providing a limiting retaining ring 9c with an outer diameter larger than the outer diameter of the upper opening of the guiding hole 7c at the other end of the guiding rod 6c, the moving range of the guiding rod 6c is effectively limited, ensuring that it reciprocates within a preset stroke, thereby avoiding improper clamping of the filter caused by excessive movement of the floating clamping block 3c. A screw is provided on the end face of the limiting retaining ring 9c away from the guiding rod 6c. A through hole is provided in the middle of the limiting retaining ring 9c. A threaded hole is provided at the other end of the guiding rod 6c. The threaded section of the screw passes through the through hole until it is connected to the threaded hole. By connecting the threaded section of the screw through the through hole in the middle of the limiting retaining ring 9c to the threaded hole at the other end of the guiding rod 6c, the fixing method of the limiting retaining ring 9c is simple and reliable, facilitating adjustment and maintenance. At the same time, this adjustable fixing method allows fine-tuning of the working length of the guiding rod 6c within a certain range to adapt to the clamping requirements of filters of different sizes, improving the adaptability and flexibility of the clamping plate mechanism c22.

[0094] A first V-shaped clamping opening 10c is provided on the floating clamping block 3c. A second V-shaped clamping opening 11c corresponding to the first V-shaped clamping opening 10c is provided on the auxiliary fixture 2c. The first V-shaped clamping opening 10c and the second V-shaped clamping opening 11c form a quadrilateral clamping position for clamping the filter. The contact points of the quadrilateral clamping position formed by the two V-shaped clamping openings with the filter are all tangent. There will still be a large-area surface contact at their abutting surfaces, so that filters of different specifications can be clamped with the same pair of clamping plates, and there is no need to frequently replace the main fixture 1c and the auxiliary fixture 2c, greatly improving the adaptability of the clamping plates.

[0095] Wear-resistant anti-slip blocks 12c are respectively provided on both sides of the first V-shaped clamping opening 10c and the second V-shaped clamping opening 11c. The wear-resistant anti-slip blocks 12c are made of silica gel. The wear-resistant anti-slip blocks 12c are fixed on the auxiliary fixture 2c and the floating clamping block 3c through pressing plates 13c. By providing the wear-resistant anti-slip blocks 12c, the clamping stability between the quadrilateral clamping position and the filter is improved, and its service life is extended. Further, the wear-resistant anti-slip blocks 12c are fixed on the auxiliary fixture 2c and the floating clamping block 3c through the pressing plates 13c, making the connection between the wear-resistant anti-slip blocks 12c and the auxiliary fixture 2c and the floating clamping block 3c more stable.

[0096] The fixture driving assembly includes opening clamp cylinders 14c provided on both sides of the main fixture 1c and the auxiliary fixture 2c; the output ends of the opening clamp cylinders 14c are respectively connected to the main fixture 1c and the auxiliary fixture 2c, and drive the main fixture 1c and the auxiliary fixture 2c to move towards each other or in opposite directions. The opening clamp cylinder 14c is a cylinder with two-way output at both ends. After this cylinder is connected to the main fixture 1c and the auxiliary fixture 2c, it can drive the main fixture 1c and the auxiliary fixture 2c to open or close, thereby completing clamping and loosening.

[0097] A pair of tension cylinders 15c are respectively provided in the middle of the main fixture 1c and the auxiliary fixture 2c. A connecting bolt 16c is provided between the two pairs of tension cylinders 15c. The two ends of the connecting bolt 16c are respectively threadedly connected to the output ends of a pair of tension cylinders 15c. The bodies of the tension cylinders 15c are respectively connected with a support plate 17c by screws, and the support plate 17c is connected to the main fixture 1c or the auxiliary fixture 2c by screws. The output ends (i.e., the piston rods of the cylinders) of the two pairs of tension cylinders 15c are relatively fixed through the connecting bolt 16c. The output end (i.e., the piston rod of the cylinder) of each pair of tension cylinders 15c moves relative to its own cylinder body, so as to realize the approach and separation of the two pairs of tension cylinders 15c. The two tension cylinders 15c pull against each other, playing a role in assisting the main fixture 1c and the auxiliary fixture 2c on both sides and improving the clamping stability.

[0098] Pressing wire buckles 18c are provided on both the main fixture 1c and the auxiliary fixture 2c. One end of the pressing wire buckle 18c is connected to the main fixture 1c or the auxiliary fixture 2c by screws, and an arc-shaped wire groove 19c is provided in the middle of the pressing wire buckle 18c. By providing the pressing wire buckle 18c and arranging the arc-shaped wire groove 19c in the middle, wire harnesses, air pipes, etc. can be clamped. One end of the pressing wire buckle 18c is fixed with screws, and the other end can stably clamp wire harnesses, air pipes, etc. by using its own structural form, and at the same time, it is convenient to disassemble and remove wire harnesses, air pipes, etc.

[0099] The working principle of each set of clamping plate mechanism c22: The opening clamp cylinders 14c on both sides and the two pairs of tension cylinders 15c in the middle drive the main fixture 1c and the auxiliary fixture 2c to approach each other at the same time. During the process of clamping the filter, the floating clamping block 3c will adaptively adjust the clamping force between it and the filter under the action of the fourth spring 4c and the guide rod 6c to obtain the best clamping force. By arranging a set of floating clamping blocks 3c corresponding to each clamping position on the main fixture 1c and connecting the floating clamping blocks 3c through an elastic tensioning component, the clamping force of each clamping position can be adaptively adjusted according to actual needs, ensuring the uniformity of the clamping force and the best elastic change state, thus avoiding the risk of displacement or overturning of the filter due to the loosening of some clamping openings during the transfer process, and at the same time avoiding the risk of deformation of the filter due to the over-tightening of some clamping openings during the transfer process.

[0100] The working principle of the clamping device c: When the lateral driving component and the longitudinal driving component work simultaneously, they can drive the two sets of clamping plate mechanisms c22 to move at the same time. One set of clamping plate mechanisms c22 is used to clamp the filter of the feeding device a, and the other set of clamping plate mechanisms c22 clamps the filter in the detection mechanism b. While moving simultaneously, the detected filter is transported to the discharging and transporting component d, and at the same time, the filter to be detected is transported to the detection mechanism b for detection, greatly improving the production efficiency.

[0101] The discharging and transporting component d includes a discharging conveyor belt d1. The two ends of the discharging conveyor belt d1 are linked with a sprocket drive group, and the sprocket drive group is linked with a third motor d2. The discharging and transporting component further includes a second waste discharging frame d3 and a pushing plate d4. The second waste discharging frame d3 and the pushing plate d4 are respectively arranged on both sides of the discharging conveyor belt d1, and the second waste discharging frame d3 and the pushing plate d4 are distributed oppositely. The pushing plate d4 is linked with a cylinder, and the cylinder is fixed on the frame. The discharging conveyor belt d1 can not only transport qualified filters but also remove unqualified filters. For the filters detected by the detection mechanism, the sensors in the detection mechanism will send out signals. According to the positions of the sensors that do not detect the guide rods (unqualified filters), the counting is carried out in sequence. The pushing plate d4 pushes the corresponding filters into the second waste discharging frame d3 for removal according to the unqualified positions, and the qualified filters can be discharged following the discharging conveyor belt d1, realizing full-automatic detection and waste discharging.

[0102] The transverse drive assembly and the longitudinal drive assembly work, driving the two sets of clamping plate mechanisms c22 to move simultaneously. One set of clamping plate mechanisms c22 is used to clamp the filters of the feeding device a, and the other set of clamping plate mechanisms c22 clamps the filters in the detection mechanism b. While moving simultaneously, the detected filters are transported to the discharging and transporting component d, and at the same time, the filters to be detected are transported to the detection mechanism b for detection, greatly improving the production efficiency.

[0103] For the filters detected by the detection mechanism, the sensors in the detection mechanism will send out signals. According to the positions of the sensors that do not detect the guide rods (unqualified filters), the counting is carried out in sequence. The pushing plate d4 pushes the corresponding filters into the second waste discharging frame d3 for removal according to the unqualified positions, and the qualified filters can be discharged following the discharging conveyor belt d1, realizing full-automatic detection and waste discharging.

[0104] Operating principle of the whole machine:

[0105] The material conveyor belt assembly transports the filter to the turntable 1a. The filter enters the sequential clamping station, and two groups of electromagnets 7a suck the filter. Then it rotates with the turntable 1a to the end face detection component 19a for detection. There is an end face detection hole 21a on the frame. The end face detection component 19a can detect the lower end face of the filter through the end face detection hole 21a, mainly for detecting whether there are threaded holes in the filter and whether the number of connection holes outside the threaded holes is correct. The filter will continue to rotate with the turntable 1a to below the height sensor 20a, and the height sensor 20a further detects whether the height of the filter is qualified. After two detections, the detected filters will all continue to rotate with the turntable 1a. Qualified products (that is, the cases where the height, threaded holes, and the number of connection holes outside the threaded holes are all correct) will be transported to the transfer conveyor belt assembly b after height detection. The two groups of electromagnets 7a will stop working and release the filter, and the transfer conveyor belt f1 will drive the filter to move.
