Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary devices of cover glass cross-cutting equipment, and in particular relates to a plate breaking device of cover glass cross-cutting equipment. Background Art

[0002] In recent years, the continued growth of the market for new display devices such as smartphones and tablets has led to a rapid increase in demand for cover glass. Cover glass is primarily used in the touchscreen modules of various display devices, including mobile phones and tablets. Once bonded to the outer surface of the touchscreen, the cover glass not only protects the touchscreen but can also be printed with various colors, patterns, and logos to enhance the product's aesthetics. Through processes such as cutting, CNC engraving, thinning, strengthening, coating, and printing, it exhibits high performance, including impact resistance, scratch resistance, oil resistance, anti-fingerprint protection, and enhanced light transmittance. Therefore, regardless of the touchscreen technology, a cover glass is an essential protective component, and glass cover glass, due to its high light transmittance and strong scratch resistance, has gradually become the mainstream cover glass.

[0003] In the production process of cover glass, the cross-cutting process is a very important process, and its function is to cut the cover glass continuously delivered from the previous process into a certain size according to the process requirements, and then break it by the breaking robot and send it to the next process. Therefore, the cross-cutting equipment plays a very important role in the production of cover glass. However, in the event of production abnormalities, such as failure of the breaking robot or defective products, the cover glass needs to be cut and discarded directly. There are generally two existing practices. The first is to burn it directly with fire. This method is often used when the cross-cutting equipment fails, and there is a risk of broken plates. As an improvement, the other is to break it manually after cutting. This method requires skilled operators, otherwise the breaking is unreliable, and the broken section may still be damaged, which will further increase the labor intensity of the operator. Therefore, in summary, the current cross-cutting process has insufficient reliability in breaking in operations that require cutting and removing defective cover glass, and may cause further damage to the cover glass.

[0039] The breaking plate assembly 2 is arranged on the same side as the cutter assembly 4; the breaking plate assembly 2 is located below the cutter assembly 4 along the movement direction of the glass to be broken;

[0040] The bend assembly 2 includes a drive unit, a breaking unit, and an adjustment and limiting unit. The drive unit drives the breaking unit, and the adjustment and limiting unit adjusts and limits the movement distance of the breaking unit to adjust the bend angle. The present invention utilizes this bend device to break and remove defective cover glass that needs to be broken and removed during the cross-cutting process, providing a certain degree of assurance for the entire process, improving work efficiency and reliability, and reducing manual intervention.

[0041] In some embodiments, the follower frame 1 of the present invention is mounted on a cross-cutting machine (the middle portion of the cross-cutting machine is fixedly connected to the lead screw nut and guide rod bearings, and the motor drives the lead screw, which in turn drives the follower frame 1 in up and down reciprocating motion). It reciprocates with the cross-cutting machine. During a single downward motion, the cutter assembly 4 moves downward at the same speed as the follower frame 1 and the cover glass, ensuring that the cutter assembly 4 can score a horizontal line on the cover glass. A control unit controls the movement of the anvil strip assembly 3 and the cutter assembly 4. After scoring, the cutter assembly 4 retracts, and the control unit controls the breaking assembly 2 to break the cover glass along the cutting line 6. The control unit controls the anvil strip assembly 3 to retract, and the follower frame 1 then moves upward and returns to its original position. The present invention also includes a collection member, which in this embodiment can be a collection hopper 5. The broken cover glass waste falls into the collection hopper 5 located below, thereby achieving the breaking and removal of defective cover glass. This device offers high operational reliability, requires little human intervention, and is highly efficient.

[0043] In some embodiments, the anvil strip assembly 3 of the present invention includes a base plate 31 connected to the follower frame 1, a support 32 movably mounted on the base plate 31, a buffer structure disposed on the support 32, and the support 32 is capable of moving along the base plate 31 so as to allow the buffer structure to support / detach the glass to be broken. The buffer structure includes a mounting seat 33 connected to the support 32, and an anvil strip 34 is disposed on the mounting seat 33. The anvil strip assembly 3 of the present invention includes a base plate 31, the base plate 31 is fixedly connected to the first beam 11 and the second beam 12, a support 32 movably mounted on the base plate 31, the support 32 is connected to the mounting seat 33, the mounting seat 33 is provided with an installation slot, and the anvil strip 34 is installed in the installation slot of the mounting seat 33 and pressed.

The telescopic end of the cylinder 216 is connected to a second connecting plate 215, and the second connecting plate 215 is connected to the breaking part.

[0046] As a specific embodiment, the first base plate 217 and the second base plate 221 of the utility model are fixedly connected to the follower frame 1; the second base plate 221 is placed in the middle of the follower frame 1, and the first base plate 217 is placed on both sides of the second base plate 221; each cylinder 216 is respectively placed under its corresponding first base plate 217 and fixedly connected to the first base plate 217.

[0047] In a cover glass cross-cutting device, the present invention comprises an adjustment and limiting portion comprising a second base plate 221 mounted on a follower frame 1. The second base plate 221 is provided with a bracket 220 having a through-hole. An adjustment screw 219 movably extends through the through-hole. One end of the adjustment screw 219 is connected to a breaking portion, and the other end is provided with an adjustment nut 218, which is larger than the radial dimension of the through-hole.

[0051] like Figure 2As shown, in some embodiments, the cutter assembly 4 of the present invention is placed on the follower frame 1 above the bend assembly 2, and the third base plate 403 is fixedly connected to the follower frame 1. In a specific embodiment, the specific marking process of the cutter assembly 4 is as follows: the anvil strip assembly 3 extends, the cutter group 401 extends, the motor drives the lead screw to make the follower frame 1 follow the cover glass 7 conveyed by the previous process and descend at a constant speed, the control part controls the cutter group 401 to mark along the movement of the linear actuator 402, and after marking is completed, the cutter group 401 retracts and returns, the bend assembly 2 performs the bend operation, and at the same time, the cover glass 8 that has been pre-broken after cutting rotates to a certain angle along the cutting line 6, is broken and falls into the collection hopper, and after the bend is completed, the anvil strip assembly 3 retracts, and the follower frame 1 rises and returns to the standby position.
