Description

[0050] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0051] The embodiments of the present application provide a feeding device 100, please refer to Figures 1 to 3 The feeding device 100 includes a support 1, a conveying mechanism 2 and a centering mechanism 3. The conveying mechanism 2 and the centering mechanism 3 are both arranged on the support 1, the support 1 is used to support and protect the conveying mechanism 2 and the centering mechanism 3, the conveying mechanism 2 is used to convey materials along a first direction X, and the centering mechanism 3 is used to center the materials on the conveying mechanism 2 along a second direction Y. Optionally, the materials are PCB boards, wooden boards, corrugated boards, plastic boards, metal boards, etc. Optionally, the materials are rectangular plates, circular plates, regular hexagonal plates, trapezoidal plates, etc.

[0052] It should be noted that when the conveying mechanism 2 conveys the material, the material is placed above the conveying mechanism 2, and the conveying mechanism 2 can horizontally convey the material, or convey the material obliquely upward or obliquely downward. In the embodiment of the present application, the conveying mechanism 2 conveys the material in the horizontal direction, and the conveying mechanism 2 horizontally supports the material, which is taken as an example for description. It can be understood that the second direction Y is parallel to the plane on which the conveying mechanism 2 supports the material, and is perpendicular to the first direction X, so in the embodiment of the present application, the second direction Y is taken as an example for description in the horizontal direction perpendicular to the first direction X.

[0053] For the above-described support 1, please refer to Figure 1 and Figure 2 The support 1 can be in the shape of a rectangular cylinder, and the conveying mechanism 2 and the centering mechanism 3 are installed at the hollow cavity of the support 1. Alternatively, the support 1 includes four wall plates 11 connected end to end, thereby being connected to form a rectangular cylinder.

[0054] For the above-described centering mechanism 3, please refer to Figure 3 and Figure 4 The centering mechanism 3 includes a first guide rod 31, a first push plate 32, a second push plate 33, and a first transmission assembly 34. The first guide rod 31 is arranged on the support 1, and the first guide rod 31 is parallel to the second direction Y. The first push plate 32 and the second push plate 33 are both slidably arranged on the first guide rod 31. The first transmission assembly 34 is arranged on the support 1, and the first transmission assembly 34 is in transmission connection with the first push plate 32 and the second push plate 33. The first transmission assembly 34 is used to drive the first push plate 32 and the second push plate 33 to slide along the first guide rod 31. In the embodiment of the present application, the first push plate 32 and the second push plate 33 are taken as an example for description in the case that they are parallel to each other and perpendicular to the second direction Y. In some other embodiments, the orientations of the first push plate 32 and the second push plate 33 can be adjusted according to requirements on this basis.

[0055] Exemplarily, the first guide rod 31 is a round rod, and two ends of the first guide rod 31 are connected to two oppositely arranged wall plates 11 of the support 1, and then the first guide rod 31 is installed on the support 1. The first push plate 32 and the second push plate 33 are provided with round holes matched with the first guide rod 31, and the first guide rod 31 is arranged in the round hole of the first push plate 32 and the round hole of the second push plate 33, so as to slide the first push plate 32 and the second push plate 33 on the first guide rod 31. Since the first guide rod 31 is parallel to the second direction Y, the first push plate 32 and the second push plate 33 can move relative to the conveying mechanism 2 along the second direction Y. The first transmission assembly 34 can be in transmission connection with the first push plate 32 and the second push plate 33 through gears, transmission shafts and belts and the like, and then drive the first push plate 32 and the second push plate 33 to slide along the first guide rod 31. When the first transmission assembly 34 drives the first push plate 32 and the second push plate 33 to contact the material, a pushing force parallel to the second direction Y can be applied to the material, and then the material on the conveying mechanism 2 is centered along the second direction Y.

[0056] It should be noted that the number of the first guide rod 31 can be multiple, and the multiple first guide rods 31 are arranged at intervals along the first direction X, so as to enhance the stability of the sliding of the first push plate 32 and the second push plate 33. Optionally, the number of the first guide rod 31 is two.

[0057] It should be noted that the traditional material centering is realized through guide plates, and the distance between the two guide plates is equal to the width of the material. When the material passes between the two guide plates along with the conveying mechanism 2, the centering is realized. However, the material has a tolerance. When the size of the material is too large, the material will be clamped between the two guide plates, that is, the clamping plate phenomenon occurs. When the size of the material is too small, the material cannot contact the two guide plates at the same time, and thus the centering of the material has a deviation.

[0058] However, in the embodiment of the present application, the first push plate 32 and the second push plate 33 center the material by pushing the material along the second direction Y. After the material is centered, the first push plate 32 and the second push plate 33 can be away from the material, and thus the clamping plate phenomenon is not easy to occur, that is, the problem of easy clamping of the material during centering is improved. Moreover, the distance that the first push plate 32 and the second push plate 33 move relative to the conveying mechanism 2 along the second direction Y can be controlled through the first transmission assembly 34. For example, when the size of the material is too large, the distance that the first push plate 32 and the second push plate 33 move towards the middle of the conveying mechanism 2 can be appropriately shortened. When the size of the material is too small, the distance that the first push plate 32 and the second push plate 33 move towards the middle of the conveying mechanism 2 can be appropriately increased, and thus the problem of deviation of the material centering is improved.

[0059] Further, the first transmission assembly 34 is configured to drive the first push plate 32 and the second push plate 33 to move towards or away from each other synchronously. That is, the first push plate 32 and the second push plate 33 always have equal distance to the same symmetry plane, which can be understood as that the symmetry plane has equal distance to both ends of the material along the second direction Y after the material is centered, so that when the first push plate 32 and the second push plate 33 move to contact the material at the same time, the symmetry axis of the material coincides with the symmetry plane, that is, the material is centered. In this way, when the size of the material is too large or too small, the symmetry axis of the material eventually coincides with the above-mentioned symmetry plane, that is, the material can be centered when the size of the material is too large or too small, so as to improve the problem of poor material centering effect.

[0060] For the above-mentioned first transmission assembly 34, please refer to Figure 4 , the first transmission assembly 34 comprises a first pulley structure 341, the first pulley structure 341 comprises a first transmission belt 3412 and a plurality of first pulleys 3411. The first pulley 3411 is rotatably arranged on the support 1, and the rotation axis of the first pulley 3411 is parallel to the first direction X; the first transmission belt 3412 is tensioned on the plurality of first pulleys 3411, and the first transmission belt 3412 comprises a first tensioning section 34121 and a second tensioning section 34122 with opposite movement directions, the first tensioning section 34121 is in transmission connection with the first push plate 32, and the second tensioning section 34122 is in transmission connection with the second push plate 33. Exemplarily, the number of first pulleys 3411 is two, the two first pulleys 3411 are arranged at intervals along the second direction Y, and the first transmission belt 3412 comprises two tensioning sections when tensioned on the two first pulleys 3411, which are the first tensioning section 34121 and the second tensioning section 34122 respectively. When the first pulley 3411 rotates, the first tensioning section 34121 and the second tensioning section 34122 drive the first push plate 32 and the second push plate 33 to move towards or away from each other respectively, and the moving speed distance of the first push plate 32 and the second push plate 33 is always equal, so that the first push plate 32 and the second push plate 33 move towards or away from each other synchronously.

[0061] In some embodiments, please refer to Figure 4The first transmission assembly 34 further comprises a first transmission rod 342 and a first driver 343. The first transmission rod 342 is rotatably arranged on the support 1, and an axis of rotation of the first transmission rod 342 is parallel to the first direction X. At least one first pulley 3411 of the first pulley structure 341 is in transmission connection with the first transmission rod 342. The first driver 343 is arranged on the support 1 and is in transmission connection with the first transmission rod 342. For example, the first transmission rod 342 is a round rod, and two ends of the first transmission rod 342 are rotatably connected to two oppositely arranged wallboards 11 of the support 1, so that the first transmission rod 342 is rotatably arranged on the support 1. The first pulley 3411 is sleeved on the first transmission rod 342 and is fixedly connected with the first transmission rod 342, so that the first pulley 3411 is in transmission connection with the first transmission rod 342. The first driver 343 can be in transmission connection with the first transmission rod 342 through gears, transmission shafts, belts and the like, or can be directly in transmission connection with the first transmission rod 342, so as to drive the first transmission rod 342 and the first pulley 3411 to rotate synchronously and drive the first push plate 32 and the second push plate 33 to slide along the first guide rod 31. Optionally, the first driver 343 is a servo motor. Optionally, the first transmission rod 342 is a square rod, for example, a hexagonal rod, which can improve the problem of slippage of the first pulley 3411 rotating on the first transmission rod 342.

[0062] In other embodiments, the first transmission assembly 34 does not comprise the first transmission rod 342, and the first driver 343 is directly connected with one first pulley 3411 of the first pulley structure 341, for example, the first pulley 3411 is sleeved on an output shaft of the first driver 343.

[0063] In some embodiments, referring to Figure 4 The number of the first pulley structure 341 is multiple, and the multiple first pulley structures 341 are arranged along the first direction X. The multiple first pulley structures 341 drive the first push plate 32 and the second push plate 33 to slide along the first guide rod 31, which enhances the stability of the sliding of the first push plate 32 and the second push plate 33. When the number of the first pulley structure 341 is multiple, at least one first pulley 3411 in each first pulley structure 341 is in transmission connection with the first transmission rod 342, so as to drive the first transmission belts 3412 of the multiple first pulley structures 341 to move synchronously.

[0064] In some embodiments, referring to Figure 3 and Figure 4The centering mechanism 3 further comprises a first sensor 35, at least one first sensor 35 is arranged on the first push plate 32, and at least one first sensor 35 is arranged on the second push plate 33. The first sensor 35 is used to detect the position of the material relative to the first sensor 35. That is, the first sensor 35 detects the position of the material relative to the first push plate 32 or the second push plate 33, and then the detected data can be used to control the distance of the relative movement of the first push plate 32 and the second push plate 33 relative to the conveying mechanism 2. For example, when the first sensor 35 on the first push plate 32 and the second push plate 33 detects the material, the first driver 343 stops working, so as to ensure that the first push plate 32 and the second push plate 33 both contact the material, thereby improving the problem that the relative movement of the first push plate 32 and the second push plate 33 is not in place, resulting in poor centering effect of the material; and preventing the first push plate 32 and the second push plate 33 from moving relatively after contacting the material, thereby improving the problem that the first push plate 32 and the second push plate 33 excessively press the material, resulting in damage to the material. It can be understood that the first sensor 35 can also be arranged to detect the material in advance, that is, when the first sensor 35 detects the material, there is still a preset distance between the material and the first push plate 32 or the second push plate 33, and then the first push plate 32 or the second push plate 33 moves the preset distance to contact the material. Alternatively, the first sensor 35 is an optical sensor, for example, a diffuse reflection type photoelectric switch. When the material passes through the diffuse reflection type photoelectric switch, the material reflects the light emitted by the diffuse reflection type photoelectric switch to the diffuse reflection type photoelectric switch, so as to trigger the diffuse reflection type photoelectric switch.

[0065] In some embodiments, referring to Figure 2 、 Figure 3 and Figure 4The intermediate mechanism 3 further comprises a second sensor 36, which is arranged on the support 1 and is configured to detect the position of the first push plate 32 or the second push plate 33 relative to the support 1. By detecting the positions of the first push plate 32 and the second push plate 33, the positions of the first push plate 32 and the second push plate 33 can be limited within a safe range, the problem of the first push plate 32 and the second push plate 33 colliding with the support 1 can be improved, the problem of the connection between the first push plate 32 and the second push plate 33 and the non-tight section of the first transmission belt 3412 moving to the first transmission belt 3412 can be improved, and the service life of the feeding device 100 can be prolonged. Since the first push plate 32 and the second push plate 33 move synchronously, it is only necessary to detect the position of the first push plate 32 or the second push plate 33. It can be understood that the number of second sensors 36 is two or more, and the two or more second sensors 36 are arranged at intervals along the second direction Y, so as to detect whether the first push plate 32 or the second push plate 33 is located in the detection area corresponding to the two or more second sensors 36. Alternatively, the second sensor 36 is a slot photoelectric switch, and the first push plate 32 or the second push plate 33 is provided with a first light shielding piece 321. When the first light shielding piece 321 is located in the groove of the slot photoelectric switch, the first light shielding piece 321 blocks the light emitted by the slot photoelectric switch, thereby triggering the slot photoelectric switch.

[0066] For the above conveying mechanism 2, please refer to Figure 3 and Figure 5 The conveying mechanism 2 comprises a second guide rod 21, a second transmission assembly 23 and a plurality of conveying assemblies 22. The second guide rod 21 is arranged on the support 1 and is parallel to the second direction Y; the conveying assembly 22 is slidably arranged on the second guide rod 21, and the plurality of conveying assemblies 22 are configured to convey the material along the first direction X; the second transmission assembly 23 is arranged on the support 1 and is in transmission connection with the plurality of conveying assemblies 22, and the second transmission assembly 23 is configured to drive the conveying assembly 22 to slide along the second guide rod 21. In the embodiment of the present application, the plurality of conveying assemblies 22 are parallel to each other and are arranged at intervals along the second direction Y. In some other embodiments, the arrangement between the plurality of conveying assemblies 22 and the orientation of the conveying assembly 22 can be adjusted according to the requirements on this basis.

[0067] Exemplarily, the second guide rod 21 is a round rod, and two ends of the second guide rod 21 are respectively connected to two oppositely arranged wall plates 11 of the support 1, and then the second guide rod 21 is installed on the support 1. The conveying assembly 22 is provided with a round hole matched with the second guide rod 21, and the second guide rod 21 is arranged in the round hole of the conveying assembly 22, so that the conveying assembly 22 is slidingly installed on the second guide rod 21. Since the second guide rod 21 is parallel to the second direction Y, the conveying assembly 22 can move relative to the support 1 along the second direction Y. The second transmission assembly 23 can be drivingly connected with the conveying assembly 22 through gears, transmission shafts, belts and the like, and then drive the conveying assembly 22 to slide along the second guide rod 21, so as to adjust the spacing of the plurality of conveying assemblies 22 along the second direction Y, so that the conveying assembly 22 can be suitable for a plurality of materials with different widths along the second direction Y.

[0068] The plurality of second guide rods 21 are arranged at intervals along the first direction X, so as to enhance the stability of the sliding of the conveying assembly 22. Optionally, the number of the second guide rods 21 is two.

[0069] Further, the second transmission assembly 23 is used for driving at least two conveying assemblies 22 to move close to or away from each other synchronously. Exemplarily, referring to Figure 5 , the number of the conveying assemblies 22 is two, so that the distance between the two conveying assemblies 22 and the same symmetry plane is always equal. It can be understood that the symmetry plane is also the symmetry plane of the first push plate 32 and the second push plate 33, so that after the first push plate 32 and the second push plate 33 center the material, the material is symmetrically placed along the second direction Y on the two conveying assemblies 22, and the lengths of the two ends of the material extending out of the two conveying assemblies 22 are equal. In this way, the first push plate 32 and the second push plate 33 centering the material actually push the material to the middle of the two conveying assemblies 22, which is beneficial to increase the stability of the conveying assembly 22 supporting the material and improve the problem that the first push plate 32 and the second push plate 33 push the material to be separated from the conveying assembly 22 and cause the material to fall.

[0070] For the above-mentioned second transmission assembly 23, please refer to Figure 5The second transmission assembly 23 comprises a second belt wheel structure 231, which comprises a second transmission belt 2312 and a plurality of second belt wheels 2311. The second belt wheels 2311 are rotatably arranged on the support 1, and the rotation axes of the second belt wheels 2311 are parallel to the first direction X. The second transmission belt 2312 is tensioned on the plurality of second belt wheels 2311, and the second transmission belt 2312 comprises a third tensioning section 23121 and a fourth tensioning section 23122, which are opposite in movement direction. The third tensioning section 23121 is in transmission connection with at least one conveying assembly 22, and the fourth tensioning section 23122 is in transmission connection with at least another conveying assembly 22. For example, the number of the second belt wheels 2311 is two, and the two second belt wheels 2311 are arranged at intervals along the second direction Y. When the second transmission belt 2312 is tensioned on the two second belt wheels 2311, the second transmission belt 2312 comprises two tensioning sections, which are the third tensioning section 23121 and the fourth tensioning section 23122, respectively. When the second belt wheels 2311 rotate, the third tensioning section 23121 and the fourth tensioning section 23122 drive the two conveying assemblies 22 to move close to each other or move away from each other, respectively, and the moving speeds of the two conveying assemblies 22 are always equal, so that the two conveying assemblies 22 synchronously move close to each other or move away from each other.

[0071] In some embodiments, referring to Figure 5 The second transmission assembly 23 further comprises a second transmission rod 232 and a second driver 233. The second transmission rod 232 is rotatably arranged on the support 1, and the rotation axis of the second transmission rod 232 is parallel to the first direction X. At least one second belt wheel 2311 of the second belt wheel structure 231 is in transmission connection with the second transmission rod 232. The second driver 233 is arranged on the support 1 and is in transmission connection with the second transmission rod 232. For example, the second transmission rod 232 is a round rod, and the two ends of the second transmission rod 232 are rotatably connected to two oppositely arranged wallboards 11 of the support 1, so that the second transmission rod 232 is rotatably installed on the support 1. The second belt wheel 2311 is sleeved on the second transmission rod 232 and is fixedly connected with the second transmission rod 232, so as to drive the second belt wheel 2311 and the second transmission rod 232 in transmission connection. The second driver 233 can be in transmission connection with the second transmission rod 232 through gears, transmission shafts and belts, or can be directly in transmission connection with the second transmission rod 232, so as to drive the second transmission rod 232 and the second belt wheel 2311 to rotate synchronously and drive the conveying assembly 22 to slide along the second guide rod 21. Optionally, the second driver 233 is a servo motor. Optionally, the second transmission rod 232 is a square rod, for example, a hexagonal rod, which can improve the problem of slippage of the second belt wheel 2311 rotating on the second transmission rod 232.

[0072] In some other embodiments, the second transmission assembly 23 does not include the second transmission rod 232, and the second driver 233 is directly connected with one second pulley 2311 of the second pulley structure 231, for example, the second pulley 2311 is sleeved on the output shaft of the second driver 233.

[0073] In some embodiments, referring to Figure 5 , the number of the second pulley structures 231 is multiple, and the multiple second pulley structures 231 are arranged along the first direction X. The multiple second pulley structures 231 drive the conveying assembly 22 to slide along the second guide rod 21, which enhances the stability of the sliding of the conveying assembly 22. When the number of the second pulley structures 231 is multiple, at least one second pulley 2311 in each second pulley structure 231 is in driving connection with the second transmission rod 232, so as to drive the multiple second pulley structures 231 to move synchronously.

[0074] In some embodiments, referring to Figure 2 , Figure 3 and Figure 5 , the conveying mechanism 2 further includes a third sensor 24 arranged on the support 1, and the third sensor 24 is used to detect the position of the conveying assembly 22 relative to the support 1. By detecting the position of the conveying assembly 22, the position of the conveying assembly 22 can be limited within a safe range, which improves the problem of the conveying assembly 22 colliding with the support 1, improves the problem of the connection between the conveying assembly 22 and the second transmission belt 2312 moving to the non-tensioned section of the second transmission belt 2312, and prolongs the service life of the feeding device 100. Since the two conveying assemblies 22 move synchronously, it is only necessary to detect the position of one conveying assembly 22. It can be understood that the number of the third sensors 24 is two or more, and the two or more third sensors 24 are arranged at intervals along the second direction Y, so as to detect whether the conveying assembly 22 is located in the detection area corresponding to the two or more third sensors 24. Alternatively, the third sensor 24 is a slot photoelectric switch, and the conveying assembly 22 is provided with a second light shielding piece 2211. When the second light shielding piece 2211 is located in the groove of the slot photoelectric switch, the second light shielding piece 2211 blocks the light emitted by the slot photoelectric switch, so as to trigger the slot photoelectric switch.

[0075] For the above conveying assembly 22, referring to Figure 5The conveying assembly 22 comprises a mounting beam 221 and a third pulley structure 222. The mounting beam 221 is slidably arranged on the second guide rod 21. For example, the mounting beam 221 is provided with a circular hole which is adapted to the second guide rod 21. The second guide rod 21 is arranged in the circular hole of the mounting beam 221 to slidably mount the mounting beam 221 on the second guide rod 21. Since the second guide rod 21 is parallel to the second direction Y, the mounting beam 221 is movable relative to the support 1 along the second direction Y. The second transmission assembly 23 is drivingly connected with the mounting beam 221 through gears, transmission shafts, belts or the like to drive the mounting beam 221 to slide along the second guide rod 21.

[0076] For the third pulley structure 222, please refer to Figure 5 The third pulley structure 222 comprises a third transmission belt 2222 and a plurality of third pulleys 2221. The third pulleys 2221 are rotatably arranged on the mounting beam 221. The rotation axes of the third pulleys 2221 are parallel to the second direction Y. The third transmission belt 2222 is tensioned on the plurality of third pulleys 2221. For example, the number of the third pulleys 2221 is two. The two third pulleys 2221 are arranged along the first direction X. When the third transmission belt 2222 is tensioned on the two third pulleys 2221, the third transmission belt 2222 comprises two tensioning sections which are parallel to the first direction X. When the material is placed on the tensioning sections and the third pulleys 2221 rotate, the tensioning sections move the material along the first direction X to convey the material along the first direction X.

[0077] Further, please refer to Figure 5 The third pulley structure 222 comprises a plurality of third transmission belts 2222. The plurality of third transmission belts 2222 are all tensioned on the plurality of third pulleys 2221. The plurality of third transmission belts 2222 are arranged along the second direction Y. The cross sections of the third transmission belts are circular to reduce the friction of the material relative to the third pulley structure 222 along the second direction Y. Optionally, the third pulley structure 222 comprises two third transmission belts 2222.

[0078] Further, please refer to Figure 5The third pulley structure 222 further comprises a fourth pulley 2223, the fourth pulley 2223 is arranged between two adjacent third pulleys 2221, and the fourth pulley 2223 supports the tensioned section of the third transmission belt 2222 for supporting the material, thereby improving the problem that the third transmission belt 2222 collapses under the gravity of the material, causing the first push plate 32 or the second push plate 33 to fail to contact the material. Optionally, the number of the fourth pulleys 2223 is multiple, and the multiple fourth pulleys 2223 are arranged at intervals along the first direction X. Further, along the first direction X, the spacing between the fourth pulley 2223 and the third pulley 2221 is less than the length of the material; when the number of the fourth pulleys 2223 is multiple, along the first direction X, the spacing between two adjacent fourth pulleys 2223 is less than the length of the material, to further improve the problem that the third transmission belt 2222 collapses under the gravity of the material.

[0079] In some embodiments, referring to Figure 5 The conveying assembly 22 further comprises a third transmission rod 223 and a third driver 224. The third transmission rod 223 is rotatably arranged on the support 1, and the rotation axis of the third transmission rod 223 is parallel to the second direction Y. At least one third pulley 2221 in each third pulley structure 222 is slidably arranged on the third transmission rod 223, and the third pulley 2221 is configured to rotate synchronously with the third transmission rod 223. The third driver 224 is arranged on the support 1, and the third driver 224 is in transmission connection with the third transmission rod 223. For example, the third transmission rod 223 is a square rod, and the two ends of the third transmission rod 223 are rotatably connected to two oppositely arranged wall plates 11 of the support 1, thereby rotatably mounting the third transmission rod 223 on the support 1. The third pulley 2221 is sleeved on the third transmission rod 223 and is slidable along the third transmission rod 223, so as to drive the third transmission rod 223 and the third pulley 2221 to rotate synchronously, thereby driving the third transmission belt 2222 to move along the first direction X. Optionally, the third driver 224 is a servo motor. It can be understood that the third transmission rod 223 can be a square rod, such as a hexagonal rod, or can be a rod with a non-circular cross section, such as an elliptical cross section, a semicircular cross section, etc., as long as the third pulley 2221 cannot rotate around the third transmission rod 223.

[0080] In some embodiments, referring to Figure 2The feeding device 100 further comprises a fourth sensor 4 arranged on the support 1, which is configured to detect the position of the material relative to the support 1, i.e. whether the material is completely located on the conveying mechanism 2, so as to determine when the centering mechanism 3 starts to work. For example, the fourth sensor 4 is arranged above the end of the conveying mechanism 2 for inputting the material, and when the fourth sensor 4 continuously detects the material, it can be determined that the material is being input to the conveying mechanism 2, and then when the fourth sensor 4 fails to detect the material, it can be determined that the material has been completely located on the conveying mechanism 2, at which time the conveying mechanism 2 stops working and the centering mechanism 3 centers the material. It can be understood that the conveying mechanism 2 can have a delay when stopping working, for example, after the fourth sensor 4 fails to detect the material, the conveying mechanism 2 still conveys the material for a period of time, so that the material is closer to the middle of the conveying mechanism 2. Alternatively, the fourth sensor 4 is an optical sensor, for example, a diffuse reflection type photoelectric switch, which is triggered when the material reflects the light emitted by the diffuse reflection type photoelectric switch to the diffuse reflection type photoelectric switch as the material passes through the diffuse reflection type photoelectric switch.

[0081] The feeding device 100 of the embodiment of the present application, the first push plate 32 and the second push plate 33 are movable relative to the conveying mechanism 2 along the second direction Y to center the material, and after the material is centered, the first push plate 32 and the second push plate 33 can be away from the material, so that the problem of the material being easily stuck is improved. The first push plate 32 and the second push plate 33 are synchronously movable relative to each other to approach or move away from each other, so that the material can be centered even when the size of the material has a tolerance, and the problem of poor centering effect is improved. The conveying assembly 22 is slidable along the second guide rod 21 to adjust the spacing of the plurality of conveying assemblies 22 along the second direction Y, so that the conveying assembly 22 can be suitable for a plurality of materials with different widths along the second direction Y. The two conveying assemblies 22 are synchronously movable relative to each other to approach or move away from each other, and the material is centered and located in the middle of the two conveying assemblies 22, which is beneficial to increase the stability of the conveying assembly 22 supporting the material, and the problem of the material falling caused by the first push plate 32 and the second push plate 33 pushing the material to separate from the conveying assembly 22 is improved.
