[0046] During the manufacturing process of display screens, the screen's carrier glass is easily broken on the production line. The broken carrier glass will affect the normal operation of the production equipment, so it is necessary to clean the broken carrier glass inside the production equipment.

[0047] In current production, production equipment is typically shut down, and workers enter the equipment to manually remove broken carrier glass. However, this manual cleaning method is inefficient, resulting in long equipment downtime and increased production costs. Furthermore, the broken carrier glass is not fixed in place, and the confined space inside the production equipment makes cleaning difficult for workers and poses a high safety risk.

[0048] To solve the above problems, Figure 1As shown, this embodiment provides a suction device, which is used to suck broken carrier glass inside the production equipment. The suction device includes a mounting frame 10, a balance arm 30, a pulley mechanism 40, a suction mechanism 50 and a counterweight 60. The balance arm 30 is arranged on the mounting frame 10. The pulley mechanism 40 includes a pulley 41 and a connecting rope 42. The pulley 41 is arranged on the balance arm 30. The connecting rope 42 extends from one end in the extension direction of the balance arm 30 to the other end in the extension direction of the balance arm 30, and the connecting rope 42 is wrapped around the pulley 41. The suction mechanism 50 is connected to one end of the connecting rope 42 and is used for vacuum adsorption of the sucked object. The counterweight 60 is connected to the other end of the connecting rope 42.

[0049] During use, the balance arm 30 is partially extended into the production equipment, positioning the suction mechanism 50 within the production equipment where the adsorbed object is located, while the counterweight 60 is positioned outside the production equipment. At this point, an operator inside the production equipment can move the suction mechanism 50 to completely adsorb the adsorbed object, while another operator simultaneously moves the counterweight 60 to maintain balance between the counterweight 60 and the suction mechanism 50. Consequently, the adsorbed object can be directly vacuumed by the suction mechanism 50, eliminating the need for an operator to manually pick up the adsorbed object, resulting in high cleaning efficiency. Furthermore, the operator can simply move the suction mechanism 50 to complete the cleaning of the adsorbed object, making cleaning effortless and reducing safety risks.

[0050] It should be noted that, in this embodiment, the adsorbed part is a broken carrier glass. In other embodiments, the adsorbed part may also be other workpieces or products, which is not limited in this embodiment.

[0051] Furthermore, in this embodiment, the counterweight 60 can be a low-cost structure such as a sandbag or metal block commonly found in factories. All other structures capable of achieving the counterweight function are within the scope of protection of this embodiment. The connecting rope 42 is a steel wire rope, which has good load-bearing performance and high strength, and is not easily worn or broken during use.

[0052] like Figure 1 As shown, there are multiple pulleys 41, with pulleys 41 provided at both ends of the balancing arm 30 in the extending direction. This prevents the connecting rope 42 from rubbing against the ends of the balancing arm 30 during movement, thus preventing damage to the connecting rope 42. Specifically, in this embodiment, there are two pulleys 41, one at each end of the balancing arm 30.

[0053] like Figure 1 As shown, the contact point between the pulley 41 and the connecting rope 42 is higher than the upper end surface of the balance arm 30, so that the connecting rope 42 will not rub against the upper end surface of the balance arm 30 when moving. Therefore, the connecting rope 42 is not easily damaged and the service life of the suction device is longer.

[0054] like Figure 1 As shown, the mounting frame 10 includes a base 11 and an adjustment mechanism 12. The adjustment mechanism 12 is disposed between the base 11 and the balance arm 30 and is used to adjust the height of the balance arm 30 relative to the base 11. When the suction device is in use, the base 11 is placed on the ground. The height of the balance arm 30 relative to the base 11 can be adjusted according to the specifications of the production equipment and the position of the suctioned object. This, in turn, changes the vertical position of the balance arm 30, allowing the suction device to be used with production equipment of different specifications, thus expanding its applicability.

[0055] Specifically, if Figure 1 As shown, the adjustment mechanism 12 includes at least two adjustment parts connected in sequence, and the relative positions of any two adjacent adjustment parts in the up and down directions are adjustable. By adjusting the relative positions of any two adjacent adjustment parts in the up and down directions, the height of the adjustment mechanism 12 in the up and down directions can be changed. This adjustment method is simple and quick.

[0056] Specifically, if Figure 1 As shown, in this embodiment, the number of adjusting members is three, which are, from bottom to top, a first adjusting member 121, a second adjusting member 122, and a third adjusting member 123. The first adjusting member 121 extends in the up-down direction and is connected to the base 11. The second adjusting member 122 extends in the up-down direction and is plugged into the first adjusting member 121. The plugging position of the second adjusting member 122 in the first adjusting member 121 is adjustable. The third adjusting member 123 extends in the up-down direction and is plugged into the second adjusting member 122. The plugging position of the third adjusting member 123 in the second adjusting member 122 is adjustable. The balance arm 30 is provided on the third adjusting member 123. In addition, the adjusting mechanism 12 further includes a second fixing member (not shown in the figure) and a third fixing member (not shown in the figure). ), the second fixing member is used to fix the first adjusting member 121 and the second adjusting member 122, the first adjusting member 121 is provided with a plurality of second adjusting holes 1211 arranged at intervals along the up-down direction, the second adjusting member 122 is provided with a plurality of third adjusting holes 1221 arranged at intervals along the up-down direction, the second fixing member can pass through any second adjusting hole 1211 and any third adjusting hole 1221, the third fixing member is used to fix the second adjusting member 122 and the third adjusting member 123, the third adjusting member 123 is provided with a plurality of fourth adjusting holes 1231 arranged at intervals along the up-down direction, the third fixing member can pass through any fourth adjusting hole 1231, the second adjusting member 122 is supported on both ends of the third fixing member passing through the fourth adjusting hole 1231.

[0057] like Figure 1As shown, when it is necessary to adjust the insertion position of the second adjusting member 122 in the first adjusting member 121, first remove the second fixing member from the second adjusting hole 1211 and the third adjusting hole 1221, and then move the second adjusting member 122 up and down until the balance arm 30 is at the required height, and align the second adjusting hole 1211 and the third adjusting hole 1221 in the horizontal direction, and then re-pass the second fixing member through the aligned second adjusting hole 1211 and the third adjusting hole 1221 to fix the first adjusting member 121 and the second adjusting member 122, so that the second adjusting member 122 remains in the adjusted position. When it is necessary to adjust the insertion position of the third adjusting member 123 in the second adjusting member 122, first remove the third fixing member from the fourth adjusting hole 1231, and then move the third adjusting member 123 up and down until the balance arm 30 is at the required height, and then insert the third fixing member into the fourth adjusting hole 1231, and place the third fixing member through both ends of the fourth adjusting hole 1231 on the second adjusting member 122, and use the second adjusting member 122 to support the third fixing member, so as to fix the third adjusting member 123 at the current height. This adjustment method is quick and easy to operate, and the setting of the three adjusting members enables the minimum height of the adjustment mechanism 12 to be as small as possible when the maximum height of the adjustment mechanism 12 is the same, thereby reducing the space occupied.

[0058] In this embodiment, the second fixing member is a pin, which has a simple structure and is easy to fix. In other embodiments, the second fixing member may also be a shaft or rod, or a bolt and nut assembly, etc. All other structures that can achieve the fixing function are within the scope of protection of this embodiment. The third fixing member is a pin, which has a simple structure and is easy to fix. In other embodiments, the third fixing member may also be a shaft or rod, etc. All other structures that can achieve the fixing function are within the scope of protection of this embodiment.

[0059] In addition, if Figure 1 As shown, at least two adjacent adjusting parts can rotate relative to each other. In this way, during use, the operator can drive the balance arm 30 and the corresponding adjusting part to rotate by pulling the suction mechanism 50 or the counterweight 60, thereby conveniently changing the position of the suction mechanism 50 inside the production equipment, making the operation of the suction device more convenient.

[0060] Specifically, if Figure 1 As shown, in this embodiment, the third adjusting member 123 can rotate relative to the second adjusting member 122 , and the fixing method of the third fixing member does not interfere with the relative rotation of the third adjusting member 123 and the second adjusting member 122 .

[0061] In addition, if Figure 1As shown, the suction device further includes a first fixing member (not shown in the figure), which is used to fix the balance arm 30 to the third adjustment member 123. The balance arm 30 is provided with a first adjustment hole 31, which extends along the extension direction of the balance arm 30. The first fixing member passes through the adjustment mechanism 12 and the first adjustment hole 31, and the first fixing member can fix the mounting frame 10 at any position of the first adjustment hole 31. During use, if it is necessary to adjust the position of the mounting frame 10 in the first adjustment hole 31, the first fixing member is first removed from the third adjustment member 123 and the first adjustment hole 31, and then the balance arm 30 is moved along the extension direction of the balance arm 30 until the length of the balance arm 30 extending into the production equipment meets the operating requirements. The first fixing member is then passed through the third adjustment member 123 and the first adjustment hole 31 to fix the balance arm 30 to the third adjustment member 123. At this time, the position of the first fixing member in the length direction of the first adjustment hole 31 is different from that before adjustment. This method is simple to adjust and easy to operate. In this embodiment, the first fixing member is a bolt and nut assembly, which has a simple structure and low cost. All other structures that can achieve the fixing function are within the protection scope of this embodiment.

[0062] Specifically, if Figure 1 As shown, a fixing hole 1232 is opened on the third adjusting member 123, and the first fixing member passes through the fixing hole 1232 to fix the third adjusting member 123 and the balance arm 30, so that the adjustment of the balance arm 30 is more convenient and quick.

[0063] like Figure 1 and Figure 2 As shown, the suction mechanism 50 includes a mounting assembly 51, a plurality of suction cups 52, and a vacuum extraction member (not shown in the figure). The mounting assembly 51 is connected to one end of the connecting rope 42, and a plurality of suction cups 52 are spaced apart on the mounting assembly 51. The vacuum extraction member is connected to the suction cups 52. The vacuum extraction member can provide vacuum power for the suction cups 52, and the plurality of suction cups 52 spaced apart can absorb a larger range of adsorbed parts at once, thereby improving the adsorption efficiency. In this embodiment, the vacuum extraction member can be a structure with a simple structure and good vacuum effect, such as a vacuum generator, and this embodiment does not limit this.

[0064] like Figure 2 As shown, the mounting assembly 51 includes a connecting rod 511 and a plurality of mounting rods 512. The connecting rod 511 is connected to one end of the connecting rope 42, and the plurality of mounting rods 512 are connected to the connecting rod 511. The plurality of mounting rods 512 are arranged at intervals, and each mounting rod 512 is provided with at least one suction cup 52. The connecting rod 511 and the plurality of mounting rods 512 together form a frame structure, so that the suction cups 52 provided on the mounting rods 512 are distributed over a wide range, while minimizing the weight of the mounting assembly 51, thereby making operation more labor-saving and convenient for the operator.

[0065] like Figure 1 As shown, the suction mechanism 50 also includes a vacuum switch 53, which is used to control the connection or disconnection between the vacuum extraction component and the suction cup 52, so that the vacuum switch 53 can be used to more conveniently control the adsorption function of the suction cup 52 to prevent the suction cup 52 from being adsorbed to other structures inside the production equipment.

[0066] In addition, if Figure 1 As shown, the vacuum switch 53 is located at the mounting assembly 51, so that the operator inside the production equipment can conveniently control the on and off of the vacuum extraction member and the suction cup 52 in a timely manner according to actual conditions, making the operation faster and more flexible.

[0067] like Figure 1 As shown, the suction device also includes a moving mechanism 20, which is disposed on the base 11. The moving mechanism 20 can be used to move the suction device to any position, making it more convenient to use. In this embodiment, the moving mechanism 20 comprises a plurality of rollers, which have a simple and low-cost structure. Other structures that can achieve the movement function are also within the scope of protection of this embodiment.

[0068] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
