Abstract
Description
Technical Field
[0001] This utility model applies to the field of LCD screen production technology, and in particular relates to an LCD screen module cutting device. Background Technology
[0002] Currently, LCD screens display images by stimulating liquid crystal molecules with electric current to change their alignment and control light transmission. Their core structure includes a backlight module, a liquid crystal layer sandwiched between glass substrates, polarizing filters, and color filters. They feature low power consumption, no radiation, and soft images. To adapt to different equipment needs, LCD screen cutting machines use a cutting wheel to scribing lines to divide large glass substrates into customized sizes.
[0003] However, in current LCD screen cutting methods, after the guide rollers glide across the glass substrate surface, the substrates are not yet completely separated. The operator must manually bend the scribed lines to separate the cut substrates. For larger substrates, uneven force during manual bending can easily damage the glass edges, affecting the cutting quality. Therefore, we propose an LCD screen module cutting device. Utility Model Content
[0004] The main purpose of this invention is to provide an LCD screen module cutting device, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An LCD screen module cutting device includes a processing table, a first electric slide rail fixedly installed on the top side of the processing table, a mounting frame drivenly connected to the outer side of the first electric slide rail, a second electric slide rail fixedly installed at the top of the mounting frame, a sliding frame drivenly connected to the outer side of the second electric slide rail, an electric push rod fixedly installed on the outer side of the top of the sliding frame, and a cutting head connected to the bottom of the drive shaft of the electric push rod. The device is characterized in that: fixed frames are horizontally fixedly installed on both sides of the bottom of the processing table, and a driving mechanism is provided inside each fixed frame;
[0007] The processing machine table has mounting slots on both sides inside, and each mounting slot is equipped with a stop mechanism. A transmission mechanism is provided between the stop mechanism and the drive mechanism.
[0008] As an optional solution to the technical solution of this application, the abutting mechanism includes an abutting block, a connecting plate is movably provided on the inner sidewall of each mounting groove, an abutting block is fixedly installed on the top surface of each connecting plate, and the vertical cross section of the abutting block is an isosceles triangle.
[0009] As an optional solution to the technical solution of this application, the driving mechanism includes a bidirectional lead screw, and the bidirectional lead screw is rotatably mounted on the inner middle of each fixed frame through a bearing, and the two outer ends of each bidirectional lead screw are movably sleeved with movable sleeves.
[0010] As an optional solution to the technical solution of this application, a servo motor is fixedly installed on the top outer side of each of the fixed frames, and the side of the servo motor drive shaft is fixedly connected to the side of the bidirectional lead screw through a coupling.
[0011] As an optional solution to the technical solution of this application, the transmission mechanism includes a push rod, and a fixing block is fixedly installed on the top of the outer side of each movable sleeve and the bottom of the connecting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This application discloses an LCD screen module cutting device. By providing connecting plates on both sides of the processing machine and triangular abutment blocks on the top of the connecting plates, the device allows the operator to separate the cut glass substrate after the cutting head has slid across its surface. The cutting position is placed above the abutment blocks, and the servo motor provides a driving force to the bidirectional lead screw, causing it to rotate within the fixed frame. Combined with the rotational transmission of the bidirectional lead screw to the movable sleeves, the two sets of movable sleeves can move synchronously towards or away from each other. After moving horizontally inside the fixed frame, the push rod, in conjunction with the hinge action of the rotating shaft, causes the two ends of the push rod to rotate relative to each other on the outside of the movable sleeve and the connecting plate, respectively. The push rod can convert the horizontal moving force of the movable sleeve into a vertical pushing force on the connecting plate and the abutment block, so that the abutment block can be lifted and moved out from the inner wall of the mounting groove. The top of the abutment block can then provide a uniform abutment force to the surface of the glass substrate along the dividing line of the glass substrate, causing the glass substrate to separate from the dividing line. This avoids uneven force during separation, which would affect the cutting and separation quality of the glass substrate. Attached Figure Description

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: an LCD screen module cutting device, wherein a first electric slide rail 11 is fixedly installed on the top side of the processing machine table 1, a mounting frame 12 is driven to the outer side of the first electric slide rail 11, a second electric slide rail 13 is fixedly installed on the top of the mounting frame 12, a sliding frame 14 is driven to the outer side of the second electric slide rail 13, an electric push rod 15 is fixedly installed on the outer side of the top of the sliding frame 14, and a cutting head 16 is connected to the bottom of the drive shaft of the electric push rod 15.
[0020] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, two fixed frames 23 are horizontally fixedly installed on both sides of the bottom of the processing machine base 1. Each fixed frame 23 is equipped with a drive mechanism, which includes a bidirectional lead screw 24. The bidirectional lead screw 24 is rotatably installed on the inner middle of each fixed frame 23 through a bearing. Movable sleeves 25 are movably sleeved at both ends of the outer side of each bidirectional lead screw 24. A servo motor 28 is fixedly installed on the top of the outer side of each fixed frame 23. The side of the drive shaft of the servo motor 28 is fixedly connected to the side end of the bidirectional lead screw 24 through a coupling. Each side end of the processing machine base 1 is equipped with a corresponding control switch, which can control the start and stop of the two sets of servo motors 28 respectively.
[0021] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), the processing machine base 1 has mounting slots 2 on both sides inside. Each mounting slot 2 is equipped with a stop mechanism, and a transmission mechanism is provided between the stop mechanism and the drive mechanism. The stop mechanism includes a stop block 22. Each mounting slot 2 has a connecting plate 21 movably installed on its inner side wall. The top surface of each connecting plate 21 is fixedly installed with a stop block 22, and the vertical cross section of the stop block 22 is an isosceles triangle.
[0022] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), the transmission mechanism includes a push rod 27. Each movable sleeve 25 has a fixed block 26 fixedly installed on its outer top and connecting plate 21. The push rod 27 is inclinedly hinged between the side ends of every two sets of fixed blocks 26 through a rotating shaft. Limiting grooves 3 are opened on both sides of the bottom end of the processing machine table 1, and the limiting grooves 3 and the mounting grooves 2 are connected. The push rod 27 is slidably installed inside the limiting grooves 3.
[0023] During operation, the glass substrate of the LCD screen module to be cut is first placed on the top of the processing machine table 1. If the cutting position needs to be adjusted, the first electric slide rail 11 is activated. The first electric slide rail 11 drives the mounting frame 12 connected to the outer drive to move laterally. The second electric slide rail 13 at the top of the mounting frame 12 moves synchronously with the mounting frame 12. At the same time, the second electric slide rail 13 is activated. The second electric slide rail 13 drives the sliding frame 14 connected to the outer drive to move longitudinally. The electric push rod 15 fixed on the outer side of the top of the sliding frame 14 moves synchronously with the sliding frame 14 until the cutting head 16 connected to the bottom of the drive shaft of the electric push rod 15 moves to the position corresponding to the position to be cut of the LCD screen module. Under the operation of the first electric slide rail 11 and the second electric slide rail 13, the cutting head 16 can be driven to scratch the surface of the glass substrate to cut and separate the glass substrate.
[0024] After the glass substrate is cut, the cutting separation line on the surface of the entire glass substrate is moved above the abutment block 22. Then, the control switches corresponding to the fixed frames 23 on both sides of the bottom of the processing machine table 1 are activated to control the servo motor 28 to run. The drive shaft of the servo motor 28 drives the bidirectional lead screw 24, which is rotatably mounted on the inner middle of the fixed frame 23 through a coupling, to rotate. The movable sleeves 25, which are movably sleeved at both ends of the outer side of the bidirectional lead screw 24, move horizontally inside the fixed frame 23 synchronously or relative to each other under the threaded transmission of the bidirectional lead screw 24. The fixing block 26, which is fixed at the top of the outer side of the movable sleeve 25, moves synchronously with the movable sleeve 25. Combined with the push rod 27, which is slidably mounted on the bottom of the processing machine table 1, the block moves synchronously with the movable sleeve 25. Inside the limiting grooves 3 on both sides of the end, the movement of the fixed block 26 on the side of the movable sleeve 25 will drive one end of the push rod 27 to move. The push rod 27 rotates around the pivot, converting the horizontal movement force of the movable sleeve 25 into a vertical pushing force on the connecting plate 21. As a result, the connecting plate 21 moves upward along the inner wall of the mounting groove 2 under the push of the push rod 27. The abutment block 22 fixed on the top surface of the connecting plate 21 rises synchronously with the connecting plate 21 until the abutment block 22 moves out of the mounting groove 2 and presses against the bottom cutting separation line of the glass substrate. Under the abutment force caused by the top of the abutment block 22, the LCD screen module is separated from the cutting line, avoiding uneven force due to manual bending that affects the separation quality.
[0025] After separation, the servo motor 28 is started in reverse, the bidirectional lead screw 24 rotates in reverse, the movable sleeve 25 moves in reverse, the push rod 27 pulls the connecting plate 21 downward, the abutment block 22 retracts into the mounting slot 2 along with the connecting plate 21, the power of each component is turned off, and the LCD screen module cutting and separation operation process is completed.
