[0025] Example

[0026] Reference Figure 1 to Figure 4 As shown, the present invention discloses a ceramic substrate conveying mechanism, which comprises a base 1, a loading unit, a punching head unit, a conveying unit and a guiding and screening unit.

[0027] Loading unit:

[0028] The above-mentioned loading unit includes an exit bracket 252, an adsorption bar 1 305 and an adsorption bar 2 306, both of which have at least two degrees of freedom in the horizontal direction and the vertical direction. The exit bracket 252 is arranged on the base 1. The adsorption bar 1 305 and the adsorption bar 2 306 are arranged on the exit bracket 252 in sequence along the horizontal direction and the longitudinal direction. The bottom of the adsorption bar 1 305 is provided with an inverted "V"-shaped notch. The notch and the bottom of the adsorption bar 2 306 are both provided with air holes. The adsorption bar 1 305 can move the ceramic base strip to the material head platform 310. When the adsorption bar 1 305 absorbs a new ceramic base strip, the adsorption bar 2 306 can press on the ceramic base strip on the material head platform 310; when the adsorption bar 1 305 is ready to put a new ceramic base strip on the material head platform 310, the adsorption bar 2 306 can directly absorb the ceramic base strip on the material head platform 310; it completes the transfer of the ceramic base strip twice in one action, with high efficiency, stability and reliability.

[0029] Specifically, a feeding drive source 300 is provided at the top of the above-mentioned exit bracket 252. A horizontal driving assembly 301 is provided at the free end of the feeding drive source 300. A feeding bracket 302 is slidably provided on the driving assembly 301. A lifting drive source 303 is provided on the feeding bracket 302 in a vertical direction. A lifting bracket 304 is provided at the free end of the lifting drive source 303. Adsorption bar 1 305 and adsorption bar 2 306 are both provided at the bottom of the lifting bracket 304.

[0030] Feeding head unit:

[0031] The above-mentioned material beating head unit includes a material beating head platform 310 and a material beating head knife 311. The material beating head platform 310 and the material beating head knife 311 are both arranged on the base 1. The material beating head platform 310 is located below the adsorption bar 1 305 and is parallel to it. The horizontal length of the material beating head platform 310 is consistent with the length of the ceramic base strip. There are two material beating head knives 311, which are respectively adjacent to the two ends of the material beating head platform 310. After the adsorption bar 2 306 presses the ceramic base strip on the material beating head platform 310, the material beating head knife 311 rises rapidly to knock off the material head of the ceramic base strip, so that the ceramic base strips entering the subsequent process are all qualified products.

[0032] Conveying unit:

[0033] The conveying unit includes a conveying driving source 320 , a conveying belt 321 and a limiting plate 322 .

[0034] The above-mentioned conveying drive source 320 and conveyor belt 321 are both arranged on the base 1. The free end of the conveying drive source 320 is connected to the conveyor belt 321. The conveyor belt 321 is located on one side of the material punching head platform 310, and its conveying direction is in the horizontal direction. Two limit plates 322 are respectively arranged on both sides of the conveyor belt 321 located at the material punching head platform 310 along the conveying direction. The two limit plates 322 are close to each other above the conveyor belt 321 to form a conveying trough 323. The distance between the limit plate 322 and the upper surface of the conveyor belt is less than the thickness of the ceramic base strip. The width of the conveying trough 323 is not less than the width of the ceramic base strip. The above optimized structure can limit the longitudinal position of the ceramic base strip during transportation while ensuring easy placement, so that the direction of the ceramic base strip is unified and the ceramic base strip is prevented from detaching from the conveyor belt 321.

[0035] Correction and screening unit:

[0036] The guiding and screening unit includes a screening plate 330 , a triangular plate 331 and a sensor 337 .

[0037] The screening plate 330 includes a first screening plate parallel to the conveying direction and a second screening plate perpendicular to the conveying direction. The first screening plate is arranged on one side of the conveyor belt 321. The second screening plate is arranged above the conveyor belt 321 in the longitudinal direction.

[0038] The above-mentioned triangular plate 331 is arranged on one side of the conveyor belt 321 and is opposite to the first screening plate. The triangular plate 331 is adjacent to the outlet of the conveying trough 323, and the distance between the surface of the triangular plate 331 facing the outlet and the first screening plate gradually decreases along the conveying direction. The minimum distance between the triangular plate 331 and the first screening plate is not less than the width of the ceramic base strip. The triangular plate 331 can correct the direction of the ceramic base strip so that it is parallel to the conveying direction.

[0039] As a further improvement of the present invention, a sensor 337 is provided between the above-mentioned triangle plate 331 and the limiting plate 322. The sensor 337 can detect whether there is material stuck between the triangle plate 331 and the limiting plate 322, so as to prevent the ceramic base strip with excess parts from entering the subsequent process.

[0040] The side of the first screening plate is provided with air holes 334. A material receiver 336 and a sensor 337 are provided on one side of the conveyor belt 321. The material receiver 336 and the sensor 337 are both located where the air holes 334 are located. When defective materials appear on the conveyor belt 321, such as reversed materials or lack of materials, the sensor 337 can detect the defective materials and blow them from the conveyor belt 321 to the material receiver 336 through the air holes 334, completing automatic screening.

[0041] As a further improvement of the present invention, the end surface of the second screening plate is provided with a guide surface 335. The guide surface 335 gradually moves away from the center line of the conveyor belt 321 along the conveying direction. The guide surface 335 can make the heavy defective materials that cannot be completely blown out by the air holes 334 slide out naturally along the conveyor belt 321 under the drive of the conveyor belt 321, thereby improving the sorting effect.

[0042] The above-mentioned second screening plate is provided with a discharge tongue 332. The discharge tongue 332 and the first screening plate are respectively located on both sides of the second screening plate. The discharge tongue 332 is located above the conveying part of the next process. A discharge groove 3320 is provided at the bottom of the discharge tongue 332. The discharge groove 3320 penetrates the discharge tongue 332 and the second screening plate along the conveying direction, and its center line is colinear with the center line of the conveying groove 323. The width of the discharge groove 3320 is consistent with the width of the ceramic base strip. The discharge groove 3320 can highly determine the direction of the ceramic base strip, and naturally transition to the conveying part of the next process, so as to realize seamless docking of the ceramic base strip in a specific direction.

[0043] As a further improvement of the present invention, a trumpet-shaped guiding groove 333 is provided at the end of the discharge groove 3320 located on the side of the triangular plate 331. The guiding groove 333 can ensure that the ceramic base strip can enter the discharge groove 3320.

[0044] As a further improvement of the present invention, three sensors 337 are arranged above the first screening plate. The first sensor 337 is located behind the triangular plate 331 and is used for counting. The second sensor 337 is located behind the first sensor 337 and is used for detecting whether the ceramic base strip is a reverse material. The third sensor 337 is located behind the second sensor 337 and is at a distance from the discharge slot 3320 that is not less than the length of the ceramic base strip and is used for detecting whether the discharge slot 3320 is blocked.

[0045] Working principle:

[0046] Adsorption bar 1 305 places the ceramic base strip on the material head platform 310; when adsorption bar 1 305 adsorbs the next ceramic base strip, adsorption bar 2 306 presses on the ceramic base strip on the material head platform 310; the material head knife 311 moves upward and knocks the material head off; then adsorption bar 2 306 places the ceramic base strip into the conveying trough 323.

[0047] The ceramic base strips in the conveying trough 323 are conveyed in a specific direction driven by the conveyor belt 321. When passing through the triangular plate 331, the triangular plate 331 preliminarily guides the ceramic base strips. When the ceramic base strips reach the air hole 334, if they are defective materials, the air hole 334 will blow them off. The qualified ceramic base strips enter the discharge trough 3320 and fall onto the conveying part of the next process after being guided.

[0048] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novelties disclosed herein.
