Description

Technical Field

[0001] This application relates to the field of conveyor lines, and in particular to a ring conveyor mechanism and a functional membrane testing device having the ring conveyor mechanism. Background Technology

[0002] In related technologies, the annular conveying mechanism consists of an annular track and a conveyor plate. The conveyor plate moves cyclically along the annular track to drive the functional film to move synchronously. The functional film detection equipment is used to detect surface defects of the functional film. The functional film is used to attach to the surface of the screen printing plate to control the height of the screen printing. The conveyor plate is directly fitted onto the outer peripheral wall of the annular track. During the movement of the conveyor plate along the track, the conveyor plate is prone to offset relative to the annular track along the cross-sectional direction of the annular track. This causes the position of the conveyor plate and the detection camera of the functional film detection equipment to be misaligned. The detection camera cannot completely cover the functional film, which in turn causes some areas of the functional film to be undetectable, reducing the accuracy of the detection results. Utility Model Content

[0003] In order to reduce the offset of the conveyor plate relative to the annular track so that the detection camera can completely cover the functional membrane and improve the detection accuracy of the detection results, this application provides an annular conveyor mechanism.

[0004] This application further proposes a functional membrane testing device.

[0005] The circular conveying mechanism provided in this application adopts the following technical solution:

[0006] A ring-shaped conveying mechanism includes: a support frame having a ring track connected end to end, the outer peripheral wall of the ring track having a first guide structure; a conveying disc having a guide wheel on its bottom wall, the guide wheel being pivotally connected to the conveying disc, the outer peripheral wall of the guide wheel having a second guide structure, the first guide structure and the second guide structure being guided and mutually limiting; and a driving mechanism being drivenly connected to the conveying disc, the driving mechanism being used to drive the conveying disc to circulate along the ring track.

[0007] By adopting the above technical solution, when the conveyor plate deviates relative to the annular track along the cross-sectional direction of the annular track, the first guide structure and the second guide structure cooperate in a limiting manner. That is, the first guide structure and the second guide structure interfere with each other, thereby limiting the offset stroke of the conveyor plate relative to the annular track and reducing the amount of offset of the conveyor plate relative to the annular track. This allows the detection camera to completely cover the functional film, thereby improving the detection accuracy of the detection results.

[0008] Preferably, one of the first guide structure and the second guide structure is a guide protrusion, and the other is a guide recess. The guide protrusion extends into the guide recess, and the guide protrusion is matched with the inner peripheral wall of the guide recess.

[0009] By adopting the above technical solution, the first guide structure and the second guide structure are designed as mutually cooperating guide protrusions and guide recesses, respectively. The guide protrusion extends into the guide recess, and the guide protrusion and the inner peripheral wall of the guide recess are mutually limiting. When the conveyor plate deviates from the circular track, the guide protrusion and the inner peripheral wall of the guide recess stop and limit each other, thereby limiting the offset stroke of the conveyor plate relative to the circular track, thus effectively reducing the offset of the conveyor plate relative to the circular track, and further improving the motion stability of the conveyor plate.

[0010] Preferably, there are multiple guide wheels, which are spaced apart along the radial direction of the conveyor disc.

[0011] By adopting the above technical solution, multiple guide wheels are set on the conveyor tray, and these guide wheels are spaced apart along the radial direction of the conveyor tray, making the operation of the conveyor tray on the circular track more stable and reliable. Furthermore, two guide wheels are arranged along the second direction of the conveyor tray, and these two guide wheels guide and limit the inner and outer walls of the circular track, which can effectively limit the offset of the conveyor tray relative to the circular track. This can prevent the detection camera from failing to completely cover the functional film due to the offset of the conveyor tray, thereby improving the detection accuracy of the functional film detection equipment.

[0012] Preferably, the driving mechanism includes a driving component, a transmission wheel set, and a transmission belt. The transmission wheel set is located inside the annular track. The driving component and the transmission belt are both connected to the transmission wheel set. The transmission belt is connected to the conveyor disc. The driving component drives the transmission wheel set to rotate the transmission belt, so that the transmission belt drives the conveyor disc to circulate along the annular track.

[0013] By adopting the above technical solution, the drive mechanism uses the combination of transmission wheel set and transmission belt to enable power to be evenly transmitted to the conveyor plate, avoiding the problems of slippage or uneven power transmission caused by traditional friction drive method. Furthermore, by setting the transmission wheel set on the inner side of the ring track, the spatial layout can be optimized, avoiding interference between the drive mechanism and the equipment located on the outer side of the ring track, and improving the overall structural compactness of the ring conveyor mechanism.

[0014] Preferably, the transmission wheel assembly includes multiple transmission wheels, which are spaced apart along the circumferential direction of the support frame. The transmission belt is wound around the outer peripheral wall of the transmission wheels, and the driving member is connected and engaged with one of the multiple transmission wheels.

[0015] By adopting the above technical solution, the drive component drives a transmission wheel, which in turn drives the transmission belt to run. The transmission belt further drives other transmission wheels to run synchronously. The coordinated drive of multiple transmission wheels to rotate the transmission belt can effectively reduce the tension fluctuation of the transmission belt, making the movement of the conveyor disc along the circular track more stable and smooth, and avoiding uneven speed or vibration of the conveyor disc.

[0016] Preferably, the conveyor disc is provided with a connecting portion, the connecting portion is provided with two clearance holes, the two clearance holes are spaced apart along a first direction of the conveyor disc, the transmission member passes through the clearance holes and is threadedly connected to the clearance holes, the transmission belt is provided with a transmission part, the transmission part is sandwiched between the two transmission members and is adapted to abut against the transmission members.

[0017] By adopting the above technical solution, the transmission belt stops with one of the two transmission components through the transmission part, thereby achieving the technical effect of the transmission belt driving the conveyor disc to move. When the drive component stops working, the other transmission component stops with the transmission part, thereby counteracting the inertial motion of the conveyor disc, so that the conveyor disc can stop precisely at the preset position.

[0018] Preferably, the side wall of the transmission part is provided with an arc-shaped relief groove, the transmission member extends into the relief groove, and the transmission member is limited and engaged with the inner peripheral wall of the relief groove.

[0019] By adopting the above technical solution, by setting an arc-shaped clearance groove in the transmission part and making the transmission component fit with the inner circumferential wall of the clearance groove, the transmission component is effectively prevented from disengaging from the clearance groove, ensuring that the transmission component is always precisely aligned with the clearance groove. This ensures that the transmission component can maintain a relative position with the transmission part, and the transmission part can smoothly drive the conveyor disc to move, thus improving the stability and reliability of the equipment.

[0020] Preferably, the top wall of the conveyor plate is provided with a plurality of adsorption holes, which are spaced apart along the radial direction of the conveyor plate. The conveyor plate defines an adsorption space, which is connected to a suction device. The suction device is adapted to draw gas from the adsorption space so that the adsorption holes adsorb parts placed on the top wall of the conveyor plate.

[0021] By adopting the above technical solution, multiple adsorption holes are set on the top wall of the conveyor plate, and the adsorption space is connected to the air suction device. The air suction device draws gas from the adsorption space to create a negative pressure in the adsorption space. The multiple adsorption holes adsorb the parts onto the top wall of the conveyor plate, thereby preventing the parts from shifting or falling off during the conveying process, and achieving effective adsorption and stable fixation of the parts.

[0022] Preferably, there are multiple conveyor trays, which are spaced apart along the circumferential direction of the support frame.

[0023] By adopting the above technical solution and setting multiple conveyor discs, the working efficiency and load capacity of the ring conveyor mechanism are effectively improved. Furthermore, the configuration of multiple conveyor discs enables the simultaneous handling of multiple parts conveying tasks, avoiding the load capacity bottleneck problem that occurs when a single conveyor disc is used, thereby improving the conveying capacity of the ring conveyor mechanism.

[0024] The circular conveying mechanism provided in this application adopts the following technical solution:

[0025] A ring conveying mechanism includes: a ring conveying mechanism, wherein the ring conveying mechanism is the aforementioned ring conveying mechanism.

[0026] By adopting the above technical solution, when the conveyor plate deviates relative to the annular track along the cross-sectional direction of the annular track, the first guide structure and the second guide structure cooperate in a limiting manner. That is, the first guide structure and the second guide structure interfere with each other, thereby limiting the offset stroke of the conveyor plate relative to the annular track and reducing the amount of offset of the conveyor plate relative to the annular track. This allows the detection camera to completely cover the functional film, thereby improving the detection accuracy of the detection results.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the conveyor plate deviates relative to the annular track along the cross-sectional direction of the annular track, the first guide structure and the second guide structure engage in a limiting fit, that is, the first guide structure and the second guide structure interfere with each other, thereby limiting the offset stroke of the conveyor plate relative to the annular track and reducing the amount of offset of the conveyor plate relative to the annular track, so that the detection camera can completely cover the functional film, thereby improving the detection accuracy of the detection results;

[0029] 2. The first guide structure and the second guide structure are designed as mutually cooperating guide protrusions and guide recesses, respectively. The guide protrusions extend into the guide recesses, and the guide protrusions and the inner peripheral walls of the guide recesses are in a limiting fit. When the conveyor disc deviates from the annular track, the guide protrusions and the inner peripheral walls of the guide recesses stop and limit the movement of the conveyor disc relative to the annular track, thereby effectively reducing the amount of deviation of the conveyor disc relative to the annular track and further improving the motion stability of the conveyor disc.

[0030] 3. By setting multiple adsorption holes on the top wall of the conveyor plate and connecting the adsorption space to the air suction device, the air suction device draws gas from the adsorption space to create a negative pressure in the adsorption space. The multiple adsorption holes adsorb the parts onto the top wall of the conveyor plate, thereby preventing the parts from shifting or falling off during the conveying process, and achieving effective adsorption and stable fixation of the parts.

[0043] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0044] This application discloses a ring conveying mechanism 100.

[0045] Reference Figure 1 , Figure 3 and Figure 4 The annular conveying mechanism 100 according to the embodiments of this application includes: a support frame 1, a conveying disk 2, and a driving mechanism 3. The support frame 1 is provided with an annular track 11 connected end to end. The outer peripheral wall of the annular track 11 is provided with a first guide structure 111. Specifically, along the direction from the inside to the outside of the annular track 11, in some specific embodiments, the first guide structure 111 can be provided on the outer wall of the annular track 11; in other specific embodiments, the first guide structure 111 can be provided on the inner wall of the annular track 11; and in still other specific embodiments, the first guide structure 111 can be provided on both the outer wall and the inner wall of the annular track 11.

[0046] The bottom wall of the conveyor plate 2 is provided with a guide wheel 21, which is pivotally connected to the conveyor plate 2. The outer peripheral wall of the guide wheel 21 is provided with a second guide structure 211. The first guide structure 111 and the second guide structure 211 guide and limit each other. The drive mechanism 3 is connected to the conveyor plate 2 for transmission. The drive mechanism 3 is used to drive the conveyor plate 2 to circulate along the ring track 11.

[0047] Specifically, when the drive mechanism 3 drives the conveyor plate 2 to move cyclically along the circular track 11, the first guide structure 111 and the second guide structure 211 cooperate to prevent the conveyor plate 2 from deviating from the preset direction, thereby preventing the conveyor plate 2 from failing to drive the functional membrane to move relative to the detection camera of the functional membrane detection equipment.

[0048] Furthermore, when the conveyor plate 2 deviates relative to the annular track 11 along the cross-sectional direction of the annular track 11, the first guide structure 111 and the second guide structure 211 engage in a limiting fit, that is, the first guide structure 111 and the second guide structure 211 interfere with each other, thereby limiting the offset stroke of the conveyor plate 2 relative to the annular track 11 and reducing the amount of offset of the conveyor plate 2 relative to the annular track 11, so that the detection camera can completely cover the functional film, thereby improving the detection accuracy of the detection results.

[0049] Furthermore, the conveyor disc 2 moves cyclically along the annular track 11 via the guide wheel 21, and is limited by the first guide structure 111 and the second guide structure 211, so that the movement of the conveyor disc 2 is more stable, thereby avoiding vibration or displacement of the conveyor disc 2 that could damage the functional membrane, and thus improving the working reliability of the annular conveyor mechanism 100.

[0050] Reference Figure 4In some embodiments of this application, one of the first guide structure 111 and the second guide structure 211 is configured as a guide protrusion, and the other is configured as a guide recess. The guide protrusion extends into the guide recess, and the guide protrusion is limited and engaged with the inner peripheral wall of the guide recess.

[0051] In some specific embodiments, the first guide structure 111 is configured as a guide protrusion and the second guide structure 211 is configured as a guide recess; in other specific embodiments, the first guide structure 111 is configured as a guide recess and the second guide structure 211 is configured as a guide protrusion.

[0052] The first guide structure 111 and the second guide structure 211 are designed as a guide protrusion and a guide recess that cooperate with each other. The guide protrusion extends into the guide recess and is limited by the inner peripheral wall of the guide recess. When the conveyor plate 2 deviates from the annular track 11, the guide protrusion and the inner peripheral wall of the guide recess stop and limit the deviation of the conveyor plate 2 from the annular track 11, thereby effectively reducing the deviation of the conveyor plate 2 from the annular track 11 and further improving the motion stability of the conveyor plate 2.

[0053] Reference Figure 3 and Figure 4 In some embodiments of this application, there are multiple guide wheels 21, which are spaced apart along the radial direction of the conveyor disk 2. Specifically, the multiple guide wheels 21 are spaced apart along a first direction of the conveyor disk 2 and also spaced apart along a second direction of the conveyor disk 2. Along the second direction of the conveyor disk 2, there are two guide wheels 21, and along the first direction of the conveyor disk 2, there are multiple guide wheels 21. The first direction of the conveyor disk 2 can refer to... Figure 1 The front-to-back direction in the middle, the second direction of the conveyor plate 2 can refer to the front-to-back direction. Figure 1 The left and right directions in the middle.

[0054] Along the second direction of the conveyor plate 2, the annular track 11 is located between the two guide wheels 21. Along the direction from the inside to the outside of the annular track 11, the first guide structure 111 is provided on the outer side wall and the inner side wall of the annular track 11. The second guide structure 211 of the two guide wheels 21 guides and limits the corresponding first guide structure 111.

[0055] By setting multiple guide wheels 21 on the conveyor plate 2, and the multiple guide wheels 21 are spaced apart along the radial direction of the conveyor plate 2, the operation of the conveyor plate 2 on the annular track 11 is made more stable and reliable. Furthermore, the two guide wheels 21 arranged along the second direction of the conveyor plate 2 guide and limit the inner and outer side walls of the annular track 11, which can effectively limit the offset of the conveyor plate 2 relative to the annular track 11. This can prevent the detection camera from failing to completely cover the functional film due to the offset of the conveyor plate 2, thereby improving the detection accuracy of the functional film detection equipment.

[0056] Furthermore, the multiple guide wheels 21 arranged along the first direction of the conveyor plate 2 can further enhance the operational stability of the conveyor plate 2, thereby minimizing the tilting and vibration of the conveyor plate 2, reducing the risk of damage to the functional membrane, and thus improving the operational reliability of the annular conveyor mechanism 100.

[0057] Reference Figures 1-3 In some embodiments of this application, the drive mechanism 3 includes a drive member 31, a transmission wheel set 32, and a transmission belt 33. Along the direction from the inside to the outside of the circular track 11, the transmission wheel set 32 ​​is located inside the circular track 11. The drive member 31 and the transmission belt 33 are both connected to the transmission wheel set 32. The transmission belt 33 is connected and cooperates with the conveyor disc 2. The drive member 31 drives the transmission wheel set 32 ​​to rotate the transmission belt 33, so that the transmission belt 33 drives the conveyor disc 2 to circulate along the circular track 11. Specifically, the drive member 31 drives the transmission wheel set 32 ​​to rotate, the transmission wheel set 32 ​​drives the transmission belt 33 to rotate, and the transmission belt 33 drives the conveyor disc 2 to circulate along the circular track 11, thereby achieving the technical effect of the drive mechanism 3 driving the conveyor disc 2 to move.

[0058] In some specific embodiments, the drive element 31 is preferably a motor.

[0059] The drive mechanism 3 uses the combination of transmission wheel set 32 ​​and transmission belt 33 to ensure that power can be evenly transmitted to the conveyor plate 2, avoiding the slippage or uneven power transmission caused by traditional friction drive. Furthermore, by setting the transmission wheel set 32 ​​on the inner side of the ring track 11, the spatial layout can be optimized, preventing interference between the drive mechanism 3 and the equipment located on the outer side of the ring track 11, and improving the overall structural compactness of the ring conveyor mechanism 100.

[0060] Reference Figures 1-3 In some embodiments of this application, the transmission wheel assembly 32 includes a plurality of transmission wheels 321, which are spaced apart along the circumferential direction of the support frame 1. The transmission belt 33 is wound around the outer peripheral wall of the transmission wheel 321, and the driving member 31 is connected and engaged with one of the plurality of transmission wheels 321.

[0061] Specifically, the driving member 31 drives one of the multiple transmission wheels 321 to rotate. The transmission wheel 321 driven by the driving member 31 drives the other transmission wheels 321 to rotate through the transmission belt 33. The multiple transmission wheels 321 together drive the transmission belt 33 to rotate.

[0062] The drive unit 31 drives a transmission wheel 321, which in turn drives the transmission belt 33 to run. The transmission belt 33 further drives other transmission wheels 321 to run synchronously. The coordinated drive of multiple transmission wheels 321 to rotate the transmission belt 33 can effectively reduce the tension fluctuation of the transmission belt 33, making the movement of the conveyor disc 2 along the circular track 11 more stable and smooth, and avoiding uneven speed or vibration of the conveyor disc 2.

[0063] Reference Figure 5 and Figure 6 In some embodiments of this application, the bottom wall of the conveyor plate 2 is provided with a connecting part 22, the connecting part 22 is provided with two clearance holes 221, the two clearance holes 221 are spaced apart along the first direction of the conveyor plate 2, the transmission member 222 passes through the clearance hole 221 and is threadedly connected to the clearance hole 221, the transmission belt 33 is provided with a transmission part 331, the transmission part 331 is sandwiched between the two transmission members 222 and is adapted to abut against the transmission members 222.

[0064] Specifically, the drive member 31 drives the transmission wheel set 32 ​​to rotate the transmission belt 33, which in turn drives the transmission part 331 to rotate. The transmission part 331 abuts against one of the two transmission members 222 and drives the conveyor disc 2 to move along the circular track 11. When the conveyor disc 2 moves to the preset area, the drive member 31 stops driving the transmission wheel set 32, the transmission belt 33 stops rotating, and the other transmission member 222 abuts against the transmission part 331, so that the conveyor disc 2 stops moving.

[0065] The transmission belt 33 is stopped by the transmission part 331 and one of the two transmission members 222, thereby achieving the technical effect of the transmission belt 33 driving the conveyor disc 2 to move. When the drive member 31 stops working, the other transmission member 222 of the two transmission members 222 stops with the transmission part 331, thereby counteracting the inertial motion of the conveyor disc 2, so that the conveyor disc 2 can be accurately stopped at the preset position.

[0066] Reference Figures 5-7 In some embodiments of this application, the side wall of the transmission part 331 is provided with an arc-shaped relief groove 332, the transmission member 222 extends into the relief groove 332, and the transmission member 222 is limited and engaged with the inner peripheral wall of the relief groove 332.

[0067] In some specific embodiments, along the first direction of the conveyor plate 2, both the front end wall and the rear end wall of the transmission part 331 are provided with arc-shaped clearance grooves 332.

[0068] By setting an arc-shaped clearance groove 332 in the transmission part 331 and making the transmission component 222 fit into the inner peripheral wall of the clearance groove 332, the transmission component 222 is effectively prevented from disengaging from the clearance groove 332, ensuring that the transmission component 222 is always precisely aligned with the clearance groove 332. This ensures that the transmission component 222 can maintain a relative position with the transmission part 331, and the transmission part 331 can smoothly drive the conveyor disc 2 to move, thus improving the stability and reliability of the equipment.

[0069] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments of this application, the top wall of the conveyor plate 2 is provided with a plurality of adsorption holes 23, the plurality of adsorption holes 23 are spaced apart along the radial direction of the conveyor plate 2, the conveyor plate 2 defines an adsorption space 24, the plurality of adsorption holes 23 are all connected to the adsorption space 24, the adsorption space 24 is connected to a suction device, and the suction device is adapted to draw gas in the adsorption space 24 so that the adsorption holes 23 adsorb the parts placed on the top wall of the conveyor plate 2.

[0070] By setting multiple adsorption holes 23 on the top wall of the conveyor plate 2 and connecting the adsorption space 24 to the air suction device, the air suction device draws gas from the adsorption space 24 to create a negative pressure in the adsorption space 24. The multiple adsorption holes 23 adsorb the parts onto the top wall of the conveyor plate 2, thereby preventing the parts from shifting or falling off during the conveying process, and achieving effective adsorption and stable fixation of the parts.

[0071] In some specific embodiments, the component can be a functional membrane.

[0072] In some specific embodiments, the suction device can be an air pump, etc.

[0073] Reference Figure 1 In some embodiments of this application, there are multiple conveyor trays 2, which are spaced apart along the circumferential direction of the support frame 1.

[0074] By setting multiple conveyor discs 2, the working efficiency and load capacity of the ring conveyor mechanism 100 are effectively improved. Furthermore, the configuration of multiple conveyor discs 2 enables the simultaneous handling of multiple parts conveying tasks, avoiding the load capacity bottleneck problem that occurs when a single conveyor disc 2 is used in the process, thereby improving the conveying capacity of the ring conveyor mechanism 100.

[0075] Based on this, this application further discloses a functional membrane testing device. The functional membrane testing device according to the embodiments of this application includes: an annular conveying mechanism 100, which is used to convey the functional membrane. The annular conveying mechanism 100 is the annular conveying mechanism 100 described in the above embodiments.

[0076] According to the functional membrane testing equipment described in the embodiments of this application, the annular conveying mechanism 100 is disposed in the functional membrane testing equipment. When the conveying disk 2 is offset relative to the annular track 11 along the cross-sectional direction of the annular track 11, the first guide structure 111 and the second guide structure 211 are in a limiting cooperation, that is, the first guide structure 111 and the second guide structure 211 interfere with each other, thereby limiting the offset stroke of the conveying disk 2 relative to the annular track 11, reducing the offset amount of the conveying disk 2 relative to the annular track 11, so that the testing camera can completely cover the functional membrane, thereby improving the detection accuracy of the test results.

[0077] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
