[0035] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0036] Reference Figures 1 to 4An example of the utility model provides an adjustable width conveying mechanism, including a base plate 1, a fixed block 2, a moving block 3, a first conveyor belt 4, a second conveyor belt 5, a first driving member 6 and a second driving member 7. The fixed block 2 is fixed on the base plate 1, and the moving block 3 is slidably connected to the base plate 1. The fixed block 2 and the moving block 3 are parallel to each other. The first conveyor belt 4 is arranged on the side of the fixed block 2 close to the moving block 3, and the second conveyor belt 5 is arranged on the side of the moving block 3 close to the fixed block 2. The first driving member 6 is used to drive the first conveyor belt 4 and the second conveyor belt 5 to rotate synchronously. The second driving member 7 is used to drive the moving block 3 close to or away from the fixed block 2. The first conveyor belt 4 and the second conveyor belt 5 are respectively used to support the bottom sides of the ceramic substrate 10.

[0037] During operation, the second driving member 7 drives the moving block 3 away from the fixed block 2, so that the distance between the fixed block 2 and the moving block 3 is greater than the width of the ceramic substrate 10. Then, the ceramic substrate 10 is placed flat on the first conveyor belt 4 and the second conveyor belt 5. Then, the second driving member 7 drives the moving block 3 to approach the fixed block 2, so that the opposite sides of the moving block 3 and the fixed block 2 limit the two sides of the width direction of the ceramic substrate 10 respectively. Then, the first driving member 6 drives the first conveyor belt 4 and the second conveyor belt 5 to rotate synchronously to drive the ceramic substrate 10 to move horizontally, thereby achieving precise positioning of the ceramic substrate 10, so that the grasping robot on the detection equipment (not shown in the figure) can accurately grasp the ceramic substrate 10, and it can also adapt to ceramic substrates 10 of different widths.

[0038] Reference Figures 2 to 5 In some preferred embodiments, the first conveyor belt 4 includes a first driving wheel 41, a first driven wheel 42 and a first belt 43 wound on the first driving wheel 41 and the first driven wheel 42, the second conveyor belt 5 includes a second driving wheel 51, a second driven wheel 52 and a second belt 53 wound on the second driving wheel 51 and the second driven wheel 52, the first driving member 6 includes a motor 61, a D-shaped shaft 62 and a coupling 63 for connecting the main shaft of the motor 61 and the D-shaped shaft 62, the motor 61 is installed on the moving block 3, the second driving wheel 51 is fixedly connected to the main shaft of the motor 61, a D-shaped groove 411 is provided in the center of the first driving wheel 41, the D-shaped groove 411 is slidably matched with the D-shaped shaft 62, and the axial direction of the D-shaped shaft 62 is the same as the moving direction of the moving block 3.

[0039] It can be understood that the motor 61 drives the second driving wheel 51 to rotate, and the second driving wheel 51 drives the second belt 53 to rotate, so that the second driven wheel 52 rotates synchronously. At the same time, the main shaft of the motor 61 drives the D-shaped shaft 62 to rotate, and the D-shaped shaft drives the first driving wheel 41 to rotate, and the first driving wheel 41 drives the first belt 43 to rotate, so that the first driven wheel 42 rotates synchronously. Moreover, when the second driving member 7 drives the moving block 3 to approach or move away from the fixed block 2, the moving block 3 drives the motor 61, the coupling 63 and the D-shaped shaft 62 to move as a whole, and the D-shaped shaft 62 slides relative to the D-shaped groove 411 on the first driving wheel 41. Therefore, one motor 61 can simultaneously drive the first belt 43 and the second belt 53 to rotate synchronously, thereby reducing the manufacturing cost of the equipment.

[0040] In some preferred embodiments, the second driving member 7 includes a mounting base 71 and a cylinder 72. The mounting base 71 is fixed on the base plate 1, and the cylinder 72 is installed on the mounting base 71. The moving block 3 is connected to the telescopic end of the cylinder 72. When the cylinder 72 extends, the cylinder 72 drives the moving block 3 to approach the fixed block 2. When the cylinder 72 retracts, the cylinder 72 drives the moving block 3 away from the fixed block 2. The cylinder 72 has a simple structure, is easy to arrange, and has a low manufacturing cost.

[0041] Reference Figure 4 Furthermore, the mounting seat 71 is provided with a first limiting groove 711 , and a buffer member 31 is provided at the bottom of the moving block 3 , and the buffer member 31 is located in the first limiting groove 711 .

[0042] When the cylinder 72 drives the moving block 3 to approach the fixed block 2, the moving block 3 drives the buffer 31 to move together, and one of the inner walls of the first limiting groove 711 limits one side of the buffer 31, thereby buffering the impact of the moving block 3 on the ceramic substrate 10. At the same time, it can also prevent the moving block 3 and the fixed block 2 from clamping the ceramic substrate 10.

[0043] When the cylinder 72 drives the moving block 3 away from the fixed block 2, the moving block 3 drives the buffer 31 to move together, and the other inner wall of the first limiting groove 711 limits the other side of the buffer 31, thereby accurately controlling the movement amplitude of the moving block 3 and preventing the distance between the moving block 3 and the fixed block 2 from being too large, which causes the ceramic substrate 10 to be unable to be placed on the first conveyor belt 4 and the second conveyor belt 5 at the same time.

[0044] Reference Figure 6In some preferred embodiments, a tensioning assembly 8 is provided on both the movable block 3 and the fixed block 2. The tensioning assembly 8 includes a first support 81 and a tensioning pulley 82 rotatably connected to the first support 81. The tensioning pulley 82 is located directly below the first belt 43 or the second belt 53. The movable block 3 and the fixed block 2 are both provided with threaded holes. The first support 81 is fixed to the threaded holes by bolts. The first support 81 is provided with a waist-shaped hole 811. The waist-shaped hole 811 is vertically arranged to accommodate the screw rod of the bolt.

[0045] It can be understood that the bolts are loosened first, and the first support 81 is moved along the length direction of the waist-shaped hole 811. The first support 81 drives the tensioning wheel 82 to move up and down, so that the tensioning wheel 82 is pressed against the first belt 43 or the second belt 53, so that the first belt 43 or the second belt 53 is in a taut state. Then, the first support 81 is fixed to the fixed block 2 or the movable block 3 by tightening the bolts. Thereby, the tightness of the first belt 43 or the second belt 53 can be adjusted to prevent the first belt 43 or the second belt 53 from detaching, thereby ensuring the stable operation of the equipment.

[0046] Furthermore, a second limiting groove 812 is provided on the first support 81, and the second limiting groove 812 is used to limit the sides of the first belt 43 and the second belt 53, thereby preventing the first belt 43 or the second belt 53 from shifting to both sides, further preventing the first belt 43 or the second belt 53 from detaching.

[0047] In some preferred embodiments, a guide assembly 9 is provided on both the movable block 3 and the fixed block 2. The guide assembly 9 includes a second support 91 and a guide wheel 92 rotatably connected to the second support 91. The second support 91 is fixed on the fixed block 2 or the movable block 3. The guide wheel 92 is located directly above the first driven wheel 42 or the second driven wheel 52.

[0048] It can be understood that a feed gap is formed between the guide wheel 92 and the first belt 43 on the first driven wheel 42 or the second belt 53 on the second driven wheel 52, and the ceramic substrate 10 enters along the feed gap. The first driven wheel 42 and the second driven wheel 52 can support the ceramic substrate 10 on the first belt 43 and the second belt 53, and the guide wheel 92 can guide the ceramic substrate 10. At the same time, the guide wheel 92 can limit the top of the ceramic substrate 10, thereby ensuring that the ceramic substrate 10 always remains in contact with the first belt 43 and the second belt 53, preventing the ceramic substrate 10 from slipping and ensuring the normal transportation of the ceramic substrate 10.

[0049] In some preferred embodiments, a limit baffle is provided at one end of the fixed block 2, and the limit baffle is higher than the first belt 43. The limit baffle is used to limit one side of the forward direction of the ceramic substrate 10. When the ceramic substrate 10 is conveyed to one end of the fixed block 2, the limit baffle abuts against one side of the ceramic substrate 10 to prevent the ceramic substrate 10 from moving, thereby achieving the positioning of the ceramic substrate 10, so that the grasping robot of the detection equipment can accurately grasp the ceramic substrate 10.

[0050] In some preferred embodiments, a linear guide rail 11 is provided between the moving block 3 and the base plate 1. The length direction of the linear guide rail 11 is perpendicular to the conveying direction of the ceramic substrate 10. When the cylinder 72 drives the moving block 3 to approach or move away from the fixed block 2, the moving block 3 can slide along the length direction of the linear guide rail 11, thereby ensuring the stability of the moving block 3 during movement and keeping the moving block 3 parallel to the fixed block 2 at all times.

[0051] In some preferred embodiments, a clearance groove 22 is provided on the top of the fixed block 2 and the movable block 3. The clearance groove 22 is used to avoid the grasping robot that grasps the ceramic substrate 10, thereby facilitating the grasping robot of the detection equipment to grasp the ceramic substrate 10.

[0052] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
