DETAILED DESCRIPTION

[0048] The core of this application is to provide a detection device to improve the detection efficiency and accuracy of product quality.

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] Planar electromagnetic headphones are a type of high-end audio device that uses a planar diaphragm unit. They use electromagnetic force to drive a large-area planar diaphragm to produce sound. They are loved by a large number of users for their unique sound-producing method and sound quality, as well as their relatively comfortable wearing experience.

[0051] Planar electromagnetic headphones are usually composed of magnets, PC sheets and iron bowl components. The assembly quality inspection process of magnets, PC sheets and iron bowl components in traditional planar electromagnetic headphones mainly relies on manual operation. This method not only leads to high labor costs, but also is subject to the instability of manual inspection, which easily leads to uneven inspection quality and low efficiency.

[0052] For this reason, Figure 1 As shown, the embodiment of the present application discloses a testing device, including a workbench 100. The material tray containing the test pieces is transferred from the loading station 300 to the testing station 400 and the sorting station 500 through the streamline 200 set on the workbench 100, thereby completing the testing process of the test pieces, reducing the manual operation process, saving labor costs, and improving the testing efficiency and accuracy of product quality.

[0053] The following will be combined Figures 1 to 11 The detection device disclosed in the embodiments of the present application is specifically explained and illustrated.

[0054] Among them, Figure 1As shown, a streamline 200 for transferring the test pieces to different stations is provided on the workbench 100, and a loading station 300, a testing station 400 and a sorting station 500 are sequentially provided along the direction of the streamline 200, and the loading station 300 is provided with a loading mechanism 301, through which the material tray containing the test pieces can be divided onto the streamline 200, and the material tray containing the test pieces can be sequentially transferred to the testing station 400 and the sorting station 500 through the streamline 200. After the test pieces are tested at the testing station 400, the unqualified products are calibrated at the same time, and the unqualified products in the test pieces are screened out by the sorting station 500, thereby completing the testing process of the test pieces. As can be seen from the above example, the material tray containing the test parts is transferred from the loading station 300 to the testing station 400 and the sorting station 500 through the streamline 200 set on the workbench 100, thereby completing the testing process of the test parts, reducing the manual operation process, saving labor costs, and improving the efficiency and accuracy of product quality testing.

[0055] In some embodiments, Figure 1 As shown, a first guide rail 402 and a second guide rail 403 are arranged above the streamline 200, and the first guide rail 402 can move along the second guide rail 403. At the same time, first mounting frames 101 are respectively arranged on both sides of the streamline 200 to fix the two parallel second guide rails 403 on the workbench 100, and are respectively located on both sides of the streamline 200, and the first guide rail 402 is supported on the two second guide rails 403 and can move along the second guide rails 403, so that the detection device 401 movably arranged on the first guide rail 402 can move along the x direction and the y direction, so that the detection device 401 can detect the detection piece at the detection station 400. In this embodiment, the detection device 401 may include a visual detection camera and a mounting seat for mounting the visual detection camera on the first guide rail 402, and the mounting seat can move along the first guide rail 402.

[0056] Furthermore, a telescopic cylinder can be provided on the mounting seat to drive the detection device 401 to move along the z direction. At the same time, the mounting seat is connected to the visual detection camera through a pin, and the visual detection camera can rotate along the pin to adjust the pitch angle of the visual detection camera, thereby ensuring the amount of light entering the light source and improving the detection accuracy.

[0057] Furthermore, arc grooves can be symmetrically arranged along the pins on the mounting seat. When the pitch angle of the visual inspection camera is adjusted, fasteners can pass through the arc grooves and cooperate with the mounting holes on the visual inspection camera to achieve fixation between the visual inspection camera and the mounting seat.

[0058] Furthermore, a cut-off plate is provided at a position corresponding to the inspection station 400 on the streamline 200, and the cut-off plate can be connected to the lifting mechanism, and the cut-off plate is located in the middle of the streamline 200. When the material tray containing the inspection piece moves to the inspection station 400, the cut-off plate can be lifted to a position higher than the streamline 200 under the drive of the lifting mechanism to prevent the material tray from continuing to move. At this time, the inspection piece can be visually inspected by the inspection device 401 of the inspection station 400. After the inspection is completed and the unqualified products are marked, the cut-off plate is driven by the lifting mechanism to drop below the streamline 200, and the material tray can be moved to the next station.

[0059] like Figure 1 As shown, the sorting station 500 includes a first unloading station 501 disposed on one side of the streamline 200 and a second unloading station 505 disposed at one end of the streamline 200. The first unloading station 501 is used for unloading unqualified products, and the second unloading station 505 is used for unloading qualified products. The third guide rail 103 and the fourth guide rail 104 are disposed at the sorting station 500, and the third guide rail 103 and the fourth guide rail 104 are disposed above the streamline 200, and the third guide rail 103 can move along the fourth guide rail 104. At the same time, second mounting frames 101a are respectively provided on both sides of the streamline 200 to fix two parallel fourth guide rails 104 on the workbench 100, and are respectively located on both sides of the streamline 200, and the third guide rail 103 is supported on the two fourth guide rails 104 and can move along the fourth guide rails 104, so that the adsorption part 102 provided on the third guide rail 103 can move the empty material tray to the material bin where the defective products are placed to place the defective products, and at the same time, a suction nozzle is movably provided on the third guide rail 103, so that the defective products can be moved to the empty material tray through the suction nozzle.

[0060] In some embodiments, Figure 1 As shown, the adsorbent 102 includes four arms arranged to intersect and suction cups arranged at the ends of the arms, so that the four corners of the empty tray are sucked by the suction cups of the four arms, and then moved to the silo where the defective products are placed along the fourth guide rail 104 through the third guide rail 103, so as to be used to hold the defective products. At the same time, a telescopic cylinder is connected to the suction nozzle, and the height of the suction nozzle can be controlled by the telescopic cylinder, so as to facilitate the movement of the defective products to the empty tray. Of course, the adsorbent 102 can not only use a suction cup, but also a magnetic suction part, such as an electromagnet. By respectively arranging metal parts at the four corners of the empty tray, the metal parts can cooperate with the electromagnet to achieve the adsorption of the empty tray, thereby achieving the purpose of moving the empty tray to the silo where the defective products are placed.

[0061] like Figure 1 As shown, the first unloading station 501 is provided with an unloading and loading assembly. Fig.10 and Fig.11As shown, the loading and unloading assembly includes a mounting plate, a pulling mechanism 502 and a locking mechanism 503. By pulling out the first bin 5023 and the second bin 5024 through the pulling mechanism 502, an empty material tray can be placed in the first bin 5023, and the unloaded material tray of the second bin 5024 can be taken out at the same time, thereby shortening the manual loading and unloading stroke and improving the loading and unloading efficiency. In addition, the pulling mechanism 502 can be locked by the locking mechanism 503 to prevent the pulling mechanism 502 from shaking or shifting, thereby improving the stability of the loading and unloading mechanism.

[0062] Specifically, Fig.10 As shown, the pulling mechanism 502 includes a track 5021 arranged in parallel, and a slider 5022 is arranged on the mounting plate, and the track 5021 and the slider 5022 are slidably matched to realize the pulling action of the pulling mechanism 502. At the same time, two bins are arranged on the track 5021. For the convenience of understanding, the two bins are defined as a first bin 5023 and a second bin 5024, respectively. The first bin 5023 is used to place an empty material tray, and the second bin 5024 is used to place a material tray, and the second bin 5024 is located near the area where the workpiece is unloaded, so that the unloaded workpiece can be placed on the empty material tray and stacked on the second bin 5024. When loading and unloading is required, the first bin 5023 and the second bin 5024 can be pulled out by the pulling mechanism 502, and the empty material tray can be added and placed in the first bin 5023, and the material tray of the second bin 5024 can be taken out, thereby shortening the manual loading and unloading stroke and improving the loading and unloading efficiency. It should be noted that the mounting plate is a part of the workbench 100 of the detection equipment to fix other equipment and ensure the stability of the equipment. The mounting plate can be a regular-shaped plate, such as an L-shaped structural plate, a rectangular plate, etc., or a special-shaped plate to meet the actual equipment fixing requirements.

[0063] In some embodiments, the number of rails 5021 can be two, and the first bin 5023 and the second bin 5024 are coaxially arranged on the two rails 5021, so that the first bin 5023 and the second bin 5024 share the same pulling mechanism 502, thereby achieving the effect of pulling the first bin 5023 and the second bin 5024 at the same time, saving installation space, reducing the use of parts, and reducing costs. Fig.10As shown, the number of tracks 5021 can also be four, so that the first bin 5023 and the second bin 5024 are independently arranged, and the first bin 5023 and the second bin 5024 are respectively located on two adjacent tracks 5021 at different positions, that is, the first bin 5023 and the second bin 5024 respectively realize the pulling effect of the first bin 5023 and the second bin 5024 through two independent pulling mechanisms 502, so as to control the loading and unloading of materials separately, and realize more accurate loading and unloading of materials. It should be noted that the number of the first bin 5023 and the second bin 5024 can be one, two or more, respectively, and the first bin 5023 and the second bin 5024 can also be different in number, such as one first bin 5023 and two second bins 5024, or two first bins 5023 and one second bin 5024. Of course, the number of tracks 5021 can be two, so that each first material bin 5023 and second material bin 5024 are coaxially arranged on two tracks 5021. The number of tracks 5021 can also be adapted to the number of first material bins 5023 and second material bins 5024, that is, the first material bin 5023 and the second material bin 5024 are independent of each other or each material bin is independent of each other.

[0064] Furthermore, the drawing mechanism 502 includes a retracted state and a drawn-out state. When there is no need to draw the first material bin 5023 and the second material bin 5024, the drawing mechanism 502 is in the retracted state. In order to prevent the drawing mechanism 502 from shaking or shifting, the drawing mechanism 502 can be locked by the locking mechanism 503, thereby preventing the drawing mechanism 502 from shaking or shifting; when it is necessary to load and unload materials, the locking mechanism 503 can be used to release the lock of the drawing mechanism 502, and the drawing mechanism 502 can be pulled out at this time, so that the drawing mechanism 502 is in the drawn-out state, so that loading and unloading can be performed.

[0065] In some embodiments, Fig.10 and Fig.11As shown, the locking mechanism 503 can be a buckle, and a limiter 5025 cooperating with the buckle 5032 is provided on the pulling mechanism 502. Specifically, the locking mechanism 503 is connected to the mounting plate, and the locking mechanism 503 includes a rotating cylinder 5031 and a buckle 5032 connected to the rotating cylinder 5031, so that the buckle 5032 can be driven to rotate when the output shaft of the rotating cylinder 5031 rotates, and the limiter 5025 on the pulling mechanism 502 is an L-shaped structure, and one end of the limiter 5025 is connected to the pulling mechanism 502, and the other end of the limiter 5025 cooperates with the buckle 5032. When the rotating cylinder 5031 drives the buckle 5032 to rotate to the first position, the buckle 5032 abuts against the limiting portion 5025, so that the locking mechanism 503 locks the pulling mechanism 502; when the rotating cylinder 5031 drives the buckle 5032 to rotate to the second position, the buckle 5032 disengages from the limiting portion 5025, so that the track 5021 of the pulling mechanism 502 can slide with the slider 5022 of the mounting plate, thereby ensuring that the pulling mechanism 502 can be pulled out and the pulling mechanism 502 is in a pulled-out state.

[0066] Of course, the locking mechanism 503 may also be a magnetic attraction member, and a magnetic attraction portion cooperating with the magnetic attraction member is provided on the pull-out mechanism 502, and the magnetic attraction portion may be made of metal. Specifically, the magnetic attraction member may be an electromagnet, and when the electromagnet is powered on, the electromagnet becomes magnetic, and at this time the electromagnet firmly attracts the magnetic attraction portion on the pull-out mechanism 502, thereby preventing the pull-out mechanism 502 from shaking or shifting. When the electromagnet is powered off, the magnetism of the electromagnet disappears, and at this time the pull-out mechanism 502 can be pulled out.

[0067] Furthermore, if Fig.10 and Fig.11 As shown, the loading and unloading mechanism also includes a lifting mechanism 504 respectively arranged in the first material bin 5023 and the second material bin 5024. When the empty material tray on the top layer of the first material bin 5023 is taken up and loaded, the lifting mechanism 504 in the first material bin 5023 lifts the stacked empty material trays in the first material bin 5023 until the empty material trays in the first material bin 5023 are emptied. At the same time, the lifting mechanism 504 in the second material bin 5024 is lowered in sequence until the unloading material trays in the second material bin 5024 are full. At this time, the first material bin 5023 and the second material bin 5024 can be drawn out through the pulling mechanism 502, and the empty material trays are replenished into the first material bin 5023, and the unloading material trays in the second material bin 5024 are taken out at the same time.

[0068] In some embodiments, Fig.11As shown, the lifting mechanism 504 includes a power device 5041 and a support plate 5044. When loading and unloading, the material trays can be stacked and placed on the support plate 5044, so that the support plate 5044 is driven to be lifted and lowered by the power device 5041 to achieve the lifting effect of the material tray. Among them, the power device 5041 can use a screw motor, which is connected to the support plate 5044 through the screw rod of the screw motor, so as to achieve the lifting of the support plate 5044. Of course, the power device 5041 can also use a telescopic cylinder, which is connected to the support plate 5044 through the telescopic rod of the telescopic cylinder, so as to achieve the lifting of the support plate 5044.

[0069] The power device 5041 may include a driving member 5042 and a support leg 5043 connected to the driving member 5042, and the support leg 5043 is connected to the support plate 5044, so that the driving member 5042 drives the support leg 5043 to rise and fall, thereby driving the support plate 5044 to rise and fall. It should be noted that the driving member 5042 may be a guide rail hydraulic lift or a sleeve cylinder lift, etc., which is not limited herein.

[0070] Further, in order to improve the stability of the support leg 5043 supporting the support disk 5044, the number of the support legs 5043 may be, but not limited to, two, and may also be three, four or more, and the support leg 5043 adopts an L-shaped structure. The support leg 5043 has two intersecting side surfaces, and for ease of understanding, the two side surfaces of the support leg 5043 are defined as a first side surface and a second side surface, respectively, and the first side surface of the support leg 5043 supports the support disk 5044, and the second side surface of the support leg 5043 is connected to the driving member 5042. Preferably, the connection position of the two inner side surfaces of the support leg 5043 is connected by an arc transition, that is, the connection position between the first inner side surface opposite to the first side surface of the support leg 5043 and the second inner side surface opposite to the second side surface of the support leg 5043 is connected by an arc transition, so as to avoid stress concentration, which may cause cracking or fracture damage to the support leg 5043.

[0071] Furthermore, if Fig.11As shown, in order to facilitate the installation of the drawing mechanism 502, the drawing mechanism 502 further includes a support frame 5026 supporting the first material bin 5023 and the second material bin 5024, and the support frame 5026 is located above the track 5021, and the track 5021 is connected to the support frame 5026, so that the support frame 5026 can slide with the track 5021, and the lifting mechanism 504 is fixed on the support frame 5026, and a hollow area is provided on the support frame 5026, so that the support plate 5044 of the lifting mechanism 504 can be freely lifted and lowered in the hollow area to avoid being interfered by the support frame 5026. In addition, a plurality of limiting enclosures 5027 are provided on the support frame 5026, so that the first material bin 5023 and the second material bin 5024 are respectively enclosed by each limiting enclosure 5027, and the empty material tray and the unloading material tray can be limited by the limiting enclosure 5027. Specifically, there are at least four limiting enclosure plates 5027 corresponding to each silo to limit the four sides of the material tray to ensure stable lifting and lowering of the material tray.

[0072] It should be noted that in the above embodiment, the second bin 5024 can be used to place unqualified products, that is, the empty material tray in the first bin 5023 is moved to the second bin 5024 through the adsorption member 102, and the unqualified products can be moved to the empty material tray in the second bin 5024 through the suction nozzle until the second bin 5024 is full of lower material trays, and the first bin 5023 and the second bin 5024 are pulled out through the pulling mechanism 502, and the empty material trays are added and placed in the first bin 5023, and the lower material tray of the second bin 5024 is taken out, thereby shortening the manual loading and unloading strokes and improving the loading and unloading efficiency. Of course, the second bin 5024 can also be used to place qualified products, which will not be repeated in this article.

[0073] Furthermore, the detection device also includes a shell, and the pull-out mechanism 502 has a pull-out end that is easy to pull out, and the pull-out end of the pull-out mechanism 502 forms a part of the shell, so that the detection device has a simpler structure and is more convenient to operate.

[0074] like Figures 2 to 5 As shown, the streamline 200 includes a first track 201, a second track 202 and a guide assembly 203. By moving at least one of the first track 201 and the second track 202, the distance between the first track 201 and the second track 202 can be adapted to trays of different sizes, thereby improving the applicability of the streamline 200. At the same time, by connecting at least one of the first track 201 and the second track 202 with the guide assembly 203, the guide assembly 203 can guide the movement of the first track 201 and the second track 202, thereby ensuring the stability of the movement.

[0075] Specifically, Figure 2 and Figure 3As shown, the streamline 200 includes a first track 201 and a second track 202 with adjustable spacing. By moving at least one of the first track 201 and the second track 202, the spacing between the first track 201 and the second track 202 can be changed, so that the spacing between the first track 201 and the second track 202 can be adapted to trays of different sizes, thereby improving the applicability of the streamline 200. Specifically, the first track 201 can be controlled by the power component 2022 to move in a direction close to or away from the second track 202 to change the spacing between the first track 201 and the second track 202, so as to adapt to trays of different sizes and models. Of course, the power component 2022 can also be used to control the second track 202 to move toward or away from the first track 201 to change the distance between the first track 201 and the second track 202, or the power component 2022 can also be used to simultaneously control the first track 201 and the second track 202 to move toward or away from the center line of the first track 201 and the second track 202 to change the distance between the first track 201 and the second track 202, thereby adapting to different sizes and models of material trays.

[0076] Furthermore, in order to ensure the stability of at least one of the first track 201 and the second track 202 when moving and avoid deflection during movement, at least one of the first track 201 and the second track 202 is connected to the guide assembly 203, so as to guide the movement of at least one of the first track 201 and the second track 202 through the guide assembly 203 to ensure the stability of movement. Specifically, the guide assembly 203 can use a telescopic rod connected to the first track 201 and the second track 202 respectively. When the first track 201 and the second track 202 are close to or away from each other, the telescopic rod is retracted or extended, and at the same time cooperates with the power assembly 2022 to limit the movement of at least one of the first track 201 and the second track 202 to avoid deflection during movement.

[0077] It should be noted that, in the above embodiment, the power assembly 2022 may use a screw motor or a telescopic cylinder to control the movement of at least one of the first track 201 and the second track 202. In addition, when the length of the belt assembly is long, two, three or more guide assemblies 203 may be provided to cooperate with the power assembly 2022, so as to ensure the stability when moving at least one of the first track 201 and the second track 202.

[0078] In some embodiments, Figures 2 to 5As shown, a first belt 2011 is provided on the first track 201, and a second belt 2021 is provided on the second track 202, and the first belt 2011 and the second belt 2021 are arranged opposite to each other, so that the material tray can be supported on the first belt 2011 and the second belt 2021, so that the first belt 2011 and the second belt 2021 are driven to move by the rotating motor 205 arranged on the first track 201 and the second track 202, respectively, so as to transport the material tray on the first belt 2011 and the second belt 2021 to the detection station 400, so as to detect the detection piece through the detection device 401. Among them, the power component 2022 includes a screw rod 2023 and a nut 2024 matched with the screw rod 2023, and the nut 2024 is fixedly connected to any one of the first track 201 and the second track 202, so that when the screw rod 2023 is rotated, the nut 2024 drives any one of the first track 201 and the second track 202 to move closer to or away from the other.

[0079] For ease of understanding, the following explanation and description are made by taking the power assembly 2022 disposed on the second track 202 as an example. Figure 2 and Figure 3 As shown, the nut 2024 is fixedly connected to the second rail 202. When the screw rod 2023 is rotated in the forward direction, the nut 2024 will drive the second rail 202 to move toward the first rail 201, so as to reduce the distance between the first rail 201 and the second rail 202. Conversely, when the screw rod 2023 is rotated in the reverse direction, the nut 2024 will drive the second rail 202 to move away from the first rail 201, so as to increase the distance between the first rail 201 and the second rail 202, thereby adapting to the transportation of trays of different sizes.

[0080] Furthermore, if Figures 2 to 5 As shown, a connecting plate 2028 is fixed to one end of the screw rod 2023, and the guide assembly 203 is fixed to the connecting plate 2028. Specifically, the connecting plate 2028 is located on the side of the second track 202 that is away from the first track 201, and the connecting plate 2028 has an extension portion 2029 connected to the first track 201, and the extension portion 2029 is fixed to the bottom of the first track 201 through a T-shaped connecting plate, while the other end of the screw rod 2023 passes through the T-shaped connecting plate and extends out of the side of the first track 201 away from the second track 202, so that the operator can rotate the screw rod 2023 to make the nut 2024 drive the second track 202 to move in a direction close to or away from the first track 201.

[0081] In order to enable the operator to rotate the screw rod 2023 more efficiently and labor-savingly, in some embodiments, as Figure 4As shown, the power assembly 2022 also includes a handwheel 2027 disposed on the screw rod 2023, and the handwheel 2027 is located on the side of the first track 201 away from the second track 202, so that the operator can drive the screw rod 2023 to rotate by turning the handwheel 2027, thereby realizing the movement of the second track 202 towards or away from the first track 201.

[0082] Furthermore, if Figure 3 As shown, the guide assembly 203 includes a guide rod 2031 and a linear bearing 2032 sleeved on the guide rod 2031, the linear bearing 2032 is fixedly connected to any one of the first track 201 and the second track 202, and the linear bearing 2032 and the guide rod 2031 are slidably matched to guide the movement of at least one of the first track 201 and the second track 202. Specifically, one end of the guide rod 2031 is connected to the connecting plate 2028, and the other end of the guide rod 2031 is fixed to the bottom of the first track 201 through a connecting piece, and the linear bearing 2032 is fixed to the bottom of the second track 202, so that the linear bearing 2032 is sleeved on the guide rod 2031, so that the linear bearing 2032 and the guide rod 2031 are slidably matched to achieve the guiding effect of the second track 202 moving in the direction close to or away from the first track 201.

[0083] In some embodiments, Figure 3 and Figure 4 As shown, the connecting plate 2028 can adopt an L-shaped structure, and one end of the connecting plate 2028 is connected to the screw rod 2023, and the other end of the connecting plate 2028 is connected to the guide rod 2031, so that the connection and fixation of the guide component 203 and the power component 2022 are simultaneously realized through a connecting plate 2028, reducing the number of installed parts and saving costs.

[0084] Furthermore, if Figure 3As shown, the power assembly 2022 also includes a nut seat 2025, so that the nut 2024 is fixed to the bottom of the second track 202 through the nut seat 2025. At the same time, in order to ensure that the second track 202 is more stable when moving, a slide rail 2030 is provided on the extension part 2029, and a slide groove 2026 that slides with the slide rail 2030 is provided at the bottom of the nut seat 2025. When the screw rod 2023 is rotated, the nut 2024 on the screw rod 2023 moves along the axial direction of the screw rod 2023, and at the same time, the nut seat 2025 on which the nut 2024 is installed drives the second track 202 to move in a direction close to or away from the first track 201, and the slide groove 2026 at the bottom of the nut seat 2025 slides along the slide rail 2030, which can guide and limit the movement of the second track 202, ensuring that the second track 202 is more stable when moving. It should be noted that the nut 2024 and the nut seat 2025 can be connected in a detachable manner, such as bolt connection, or can be connected and fixed by welding.

[0085] It should be noted that, in the above embodiment, only the power component 2022 is used to control the second track 202 to move towards or away from the first track 201. Of course, the power component 2022 can also be used to control the first track 201 to move towards or away from the second track 202. The specific implementation method is similar to the above embodiment and will not be repeated herein.

[0086] In some embodiments, the streamline 200 may adopt a multi-section structure, and each section of the streamline 200 is correspondingly provided with one or more guide components 203. At the same time, each section of the streamline 200 is provided with a power component 2022 that can adjust the distance between the first track 201 and the second track 202, so as to realize segmented adjustment of the multiple sections of the streamline 200, thereby meeting different spacing requirements between the first track 201 and the second track 202 at different positions.

[0087] Furthermore, if Figures 2 to 5 As shown, in order to prevent the material tray from shifting when it moves on the streamline 200, a plurality of guide wheels 204 are spaced apart on the first track 201 and the second track 202, and the guide wheels 204 roll with the sides of the material tray parallel to the transport direction of the belt assembly to achieve horizontal and lateral positioning of the material tray, thereby preventing the material tray from shifting when it moves on the streamline 200 and ensuring that the material tray is more stable when moving.

[0088] like Figures 6 to 9As shown, the feeding mechanism 301 includes a feeding assembly 302 and a material dividing assembly 308. The material dividing assembly 308 and the first lifting plate 304 of the feeding assembly 302 are used to sequentially feed a plurality of stacked material trays, thereby achieving the purpose of automatic feeding, improving the feeding efficiency, and achieving continuous detection of the detection device 401. At the same time, by arranging a buffer member 3061 on the second lifting plate 306, it is possible to avoid a large impact force on the fixed plate 307 when the first lifting plate 304 drives the second lifting plate 306 to lift, thereby improving the stability of feeding.

[0089] Specifically, Figure 6 and Figure 7 As shown, the loading assembly 302 includes a driving device 303, a first lifting plate 304 and a support rod 305. The driving device 303 is connected to the first lifting plate 304 and is used to drive the lifting of the first lifting plate 304 to place the material tray located on the first lifting plate 304 on the first belt 2011 and the second belt 2021 of the streamline 200. The driving device 303 can adopt a screw motor, and by connecting the screw rod of the screw motor to the first lifting plate 304, the first lifting plate 304 is driven by the screw motor to perform a linear lifting action. In this embodiment, the driving device 303 adopts a telescopic cylinder, and by connecting the telescopic rod of the telescopic cylinder to the first lifting plate 304, the first lifting plate 304 is driven to perform a linear lifting action by the extension and contraction of the telescopic rod. It should be noted that the material tray is a device used to carry workpieces on the production line during the production process of electronic products. During inspection, the workpiece to be inspected can be placed on a material tray, and then the material tray can be placed on the first belt 2011 and the second belt 2021 of the streamline 200 through the first lifting plate 304, so that the material tray can be transported to the inspection station 400 through the streamline 200 to perform quality inspection on the workpiece to be inspected.

[0090] Furthermore, if Figure 6 and Figure 7 As shown, in order to ensure that the first belt 2011 and the second belt 2021 can support the material tray to realize the transportation process of the material tray, the distance between the first belt 2011 and the second belt 2021 needs to be ensured to be smaller than the width of the material tray in this direction. At the same time, in order to avoid the interference of the first belt 2011 and the second belt 2021 on the lifting and lowering of the first lifting plate 304, the distance between the first belt 2011 and the second belt 2021 needs to be ensured to be greater than the width of the first lifting plate 304 in this direction, so that the first lifting plate 304 can smoothly place the material tray containing the inspection piece on the first lifting plate 304 on the first belt 2011 and the second belt 2021, so as to transport the material tray to the inspection station 400 through the streamline 200 for quality inspection.

[0091] The material separation component 308 is used to separate the bottommost material tray from the stacked material trays when the first lifting plate 304 supports the stacked material trays to move to the designated upper material position. In some embodiments, the material separation component 308 can be located beside the flow line 200. When the first lifting plate 304 supports the material trays to move (including descending or ascending), the material separation component 308 can separate the bottommost material tray on the first lifting plate 304 from the stacked material trays, and at the same time, the material tray at the bottom is placed on the flow line 200 through the first lifting plate 304, thereby realizing the transportation of all the stacked material trays.

[0092] In some embodiments, Fig. 9 As shown, the material dividing assembly 308 includes a material dividing cylinder 3081 located on both sides of the first lifting plate 304 and a material dividing sheet 3082 connected to the material dividing cylinder 3081. The material dividing cylinder 3081 controls the material dividing sheet 3082 to move in the direction close to the material tray, so that the material dividing sheet 3082 is inserted between two adjacent material trays and supported on the material tray above the lowest material tray, so that the lowest material tray is separated from the stacked material trays, thereby separating the material tray at the bottom layer from the remaining material trays. It should be noted that the material dividing sheet 3082 can be inserted into the slot of the material tray above the lowest material tray, so that the material tray at the bottom layer is separated from the remaining material trays. The slot of the material tray can be formed by setting a groove on the bottom edge of the material tray, so that when the bottom of the material tray fits with the top of the adjacent material tray, a slot that is convenient for the material dividing sheet 3082 to be inserted can be formed.

[0093] When loading, first manually stack multiple trays containing workpieces to be tested on the first lifting plate 304. At this time, the first lifting plate 304 is lifted to a position above the streamline 200, and the material dividing sheet 3082 is at a position away from the tray. Then, the material dividing sheet 3082 is controlled by the material dividing cylinder 3081 to move toward the tray, so that the material dividing sheet 3082 is inserted between the tray at the bottom layer and the adjacent tray and supported on the tray above the bottom layer. At this time, all the trays above the tray at the bottom layer are supported by the material dividing sheet 3082, and then the first lifting plate 304 is lowered to a position flush with or below the streamline 200, so that the tray at the bottom layer falls on the streamline 200, thereby completing the loading of one tray. When one tray is loaded with materials, the first lifting plate 304 is lifted again to the position of the initial support tray. At this time, the material dividing cylinder 3081 controls the material dividing piece 3082 to move away from the tray, so that the material dividing piece 3082 is separated from the tray. The stacked trays fall onto the first lifting plate 304 under the action of gravity, and then the above steps are repeated to complete the loading of all the stacked trays in turn.

[0094] Furthermore, if Figure 6As shown, in order to prevent the material tray from shifting when it falls, a limiting column 309 is provided on the side of the streamline 200 opposite to the first track 201 and the second track 202, and there are at least four limiting columns 309 to limit the four corners of the material tray, thereby ensuring the stability of the material tray when it falls, and effectively preventing the material tray from shifting when it falls.

[0095] In some embodiments, Figure 6 As shown, the limiting column 309 has a limiting groove, and the limiting groove is continuously arranged along the height direction of the limiting column 309 to achieve the limiting of the material tray. The limiting groove is an L-shaped structure, so that the corner of the material tray can better fit with the limiting groove of the limiting column 309, so that the material tray can fall smoothly while ensuring the limiting of the material tray. It should be noted that the limiting column 309 can also be five, six or more, which is not limited in this article.

[0096] It can be seen from the above example that multiple stacked material trays are loaded in sequence through the material dividing component 308 and the first lifting plate 304 of the loading component 302, thereby achieving the purpose of automatic loading. Compared with the traditional manual loading method, the loading efficiency is improved, and continuous detection of the detection device 401 is realized, thereby improving the detection efficiency of the workpiece.

[0097] Furthermore, if Figures 6 to 8 As shown, one end of the support rod 305 is connected to the first lifting plate 304, and the other end of the support rod 305 is connected to the second lifting plate 306. For ease of understanding, the two ends of the support rod 305 are defined as the first end and the second end, respectively. The first end of the support rod 305 is connected to the first lifting plate 304, and the second end of the support rod 305 is connected to the second lifting plate 306. At the same time, a fixed plate 307 is arranged between the second lifting plate 306 and the first lifting plate 304, and the second end of the support rod 305 passes through the fixed plate 307 to be connected to the second lifting plate 306 located below the fixed plate 307. The support rod 305 can move in a direction perpendicular to the fixed plate 307 driven by the first lifting plate 304, so that the second lifting plate 306 can move relative to the fixed plate 307.

[0098] like Figure 8As shown, in order to prevent the second lifting plate 306 from colliding with the fixed plate 307 when lifting, thereby causing the first lifting plate 304 to generate vibration and abnormal noise, a buffer 3061 is provided on the second lifting plate 306 to avoid collision with the fixed plate 307. In this embodiment, preferably, the buffer 3061 can be adopted but not limited to an oil pressure buffer. When impacted by an external force, the piston of the oil pressure buffer squeezes the hydraulic oil in the inner tube, and the hydraulic oil is discharged from the oil discharge hole of the inner tube after being pressurized. At the same time, the discharged hydraulic oil also flows back into the inner tube through the oil return hole of the inner tube. When the external force disappears, the spring rebounds the piston back to the starting point and waits for the next action, thereby effectively reducing the speed of the moving second lifting plate 306 through the change of liquid flow and pressure, thereby achieving the effect of balanced stop. Of course, the buffer 3061 can also be a rubber pad arranged on the fixed plate 307 or the second lifting plate 306 to reduce the vibration and abnormal noise generated when the second lifting plate 306 collides with the fixed plate 307, so as to ensure the stability of feeding.

[0099] Further, there are multiple support rods 305, that is, the support rods 305 can be three, four or more. In addition, the driving device 303 includes an output shaft 3031 connected to the first lifting plate 304, and the output shaft 3031 is located at the center of each support rod 305 to ensure that the lifting of the first lifting plate 304 is more stable, and at the same time, the force of the first lifting plate 304 is more uniform. Specifically, when the driving device 303 adopts a screw motor, the output shaft 3031 is the screw rod of the screw motor, and the screw rod is located at the center of each support rod 305 to ensure the stability of the first lifting plate 304 driven by the screw motor to perform a linear lifting action. When the driving device 303 adopts a telescopic cylinder, the output shaft 3031 is the telescopic rod of the telescopic cylinder, and the telescopic rod is located at the center of each support rod 305 to ensure the stability of the first lifting plate 304 driven by the telescopic rod to perform a linear lifting action. It should be noted that the center of each support rod 305 refers to the geometric center of the figure enclosed by the lines connecting the support rods 305. In this embodiment, the number of support rods 305 is four, and each support rod 305 is symmetrically distributed at the four corners of the fixed plate 307. The figure enclosed by the lines connecting the support rods 305 is a rectangle, and the center of each support rod 305 is the geometric center of the rectangle, that is, the intersection of the lines connecting the support rods 305 at the diagonal positions.

[0100] Furthermore, if Figures 6 to 8As shown, a guide portion 3071 is provided on the fixed plate 307, and the support rod 305 passes through the guide portion 3071, and the support rod 305 can move along the guide portion 3071. The guide portion 3071 of the fixed plate 307 can guide the movement of the support rod 305, so as to ensure the stable lifting of the first lifting plate 304 and the second lifting plate 306 at both ends of the support rod 305. Among them, the guide portion 3071 can adopt a semicircular arc groove provided at the edge of the fixed plate 307, so that the support rod 305 can move up and down along the semicircular arc groove. Of course, the guide portion 3071 can also adopt a guide hole provided at the corner position of the fixed plate 307, so that the support rod 305 can move up and down along the guide hole, and the guide hole can limit the support rod 305, so as to ensure that the support rod 305 moves in a straight line. Preferably, the guide portion 3071 adopts a guide hole set at the corner position of the fixing plate 307, and a linear bearing is provided at the position of the guide hole. The linear bearing is sleeved on the outer side of the support rod 305 to make the movement of the support rod 305 more stable.

[0101] Furthermore, if Figure 6 and Figure 7 As shown, there are two second lifting plates 306 , and the two second lifting plates 306 are respectively located on both sides of the driving device 303 to avoid the second lifting plates 306 affecting the driving device 303 driving the first lifting plate 304 to rise and fall.

[0102] Furthermore, the fixing plate 307 includes a first fixing plate 3072 and second fixing plates 3073 located on both sides of the first fixing plate 3072. Figure 6 and Figure 7 As shown, the buffer 3061 can abut against the first fixed plate 3072 to prevent the second lifting plate 306 from colliding with the first fixed plate 3072 when lifting, thereby causing vibration and abnormal noise to the first lifting plate 304. Of course, the buffer 3061 can also abut against the second fixed plate 3073. Among them, the second fixed plate 3073 can be vertically arranged with the first fixed plate 3072 and located below the first fixed plate 3072. The buffer 3061 on the second lifting plate 306 abuts against the second fixed plate 3073, which can effectively shorten the travel of the driving device 303 to drive the first lifting plate 304 to lift, save energy consumption, and reduce costs.
