Abstract
Description
Technical Field
[0001] This utility model relates to the field of LCD feeding machine technology, specifically a quick-change fixture for an LCD feeding machine. Background Technology
[0002] The jig tray in an LCD loading machine is a container or pallet used to carry and support LCD panels or other components. It is typically a flat structure designed to fix and position the LCD panels for assembly, handling, and manipulation during production. Jig trays are commonly used for material handling and transfer in automated production lines.
[0003] For example, the national authorized patent announcement number CN118579515A discloses an LCD feeding machine, which relates to the field of LCD feeding technology. It includes a base plate, a carrying tray mounted on the left side of the top surface of the base plate, and several LCD components placed on the top surface of the carrying tray. A conveyor belt is mounted on the right side of the top surface of the base plate. A T-shaped plate is fixed in the middle of the top surface of the base plate. A first slide rail is fixed on the top front of the T-shaped plate, and a second slide rail slides along one side of the first slide rail. An air pump is fixed at the bottom end of the second slide rail, and a pair of suction cups are provided on the bottom surface of the air pump. A reciprocating shaft is rotatably inserted into the middle of the top edge of the T-shaped plate. A reciprocating swing arm is fixed at the front end of the reciprocating shaft and is hinged to the second slide rail. The rear end of the reciprocating shaft is connected to the T-shaped plate through a meshing assembly. This invention can continuously and automatically feed LCD components, greatly improving production speed and efficiency, completing the feeding process more quickly and accurately, saving labor and time costs, and improving the automation level of LCD component feeding.
[0004] However, the aforementioned LCD feeding machine is not convenient for replacing the fixture tray. In the LCD production process, different specifications and sizes of LCD panels require different fixture trays to be adapted. This means that when the panel specifications change, the operator needs to manually disassemble and install the fixture tray, and manually adjust the fixture tray or replace the entire fixture system, which limits the flexibility of the production line. Utility Model Content
[0005] The purpose of this invention is to provide a quick-change fixture for an LCD feeder, in order to solve the problem mentioned in the background art of not being able to easily replace the fixture tray to increase the flexibility of the production line.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A quick-change fixture for an LCD feeding machine includes: a mounting frame, a motor fixedly mounted on the lower surface of the mounting frame, the motor being fixedly mounted on the lower surface of the mounting frame, the output shaft of the motor passing through the upper surface of the mounting frame and having an insertion post fixedly mounted at its end, a fixture disc slidably inserted into the outer surface of the insertion post, threaded holes and guide cylinders respectively provided in the upper and lower halves of the insertion post, the threaded holes communicating with the guide cylinders, a pushing mechanism slidably mounted inside the guide cylinders, the pushing end of the pushing mechanism sliding within a guide rail groove, the guide rail groove being located in the lower half of the outer surface of the insertion post and communicating with the guide cylinders, the pushing mechanism being able to slide out from the guide rail groove and press against the inner wall of the insertion port of the fixture disc, thereby locking the fixture disc at the outer surface of the insertion post.
[0008] Preferably, a wing bolt is threaded into the threaded hole of the insert post, so that the threaded portion of the wing bolt can thread through into the guide cylinder and contact the upper surface of the pushing mechanism.
[0009] Preferably, the pushing mechanism includes a guide plate, which slides inside a guide cylinder. Connecting arms are fixedly installed at both ends of the outer surface of the guide plate, and sliding columns are fixedly installed on both sides of the connecting arms. The connecting arms slide into the pressing block and slide through the sliding columns on both sides into the inclined sliding grooves opened on both sides inside the pressing block. The pressing block slides in the guide rail groove.
[0010] Preferably, this allows the guide disc to slide down inside the guide cylinder under the pressure of the threaded portion of the wing bolt. As the guide disc slides down, it drives the connecting arms at both ends to slide down inside the clamping block. This allows the connecting arms to drive the sliding columns on both sides to slide and push the clamping block in the inclined groove, so that the clamping block slides outward in the guide groove and presses against the inner wall of the insertion port of the fixture disc.
[0011] Preferably, limit blocks are fixedly installed on both sides of the guide plate, and the limit blocks are slidably installed in the limit grooves, which are opened on both sides of the guide cylinder.
[0012] Preferably, a spring is provided in the limiting groove, and the upper and lower ends of the spring are respectively fixedly connected to the lower surface of the limiting groove and the lower surface of the limiting block.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Through the design of the insert column, motor, jig disc, wing bolt, and pushing mechanism, when replacing the jig disc, the wing bolt can be unscrewed from the threaded hole of the insert column. This allows the threaded part of the wing bolt to unscrew from the guide cylinder, thus releasing the pushing mechanism. The pushing end of the pushing mechanism can then slide into the guide groove, relieving pressure on the inner wall of the jig disc's insert diameter. This allows the operator to pull the jig disc out from the outer surface of the insert column. The replacement jig disc can then be inserted into the outer surface of the insert column. The operator can then screw the wing bolt back into the threaded hole, inserting the threaded part of the wing bolt into the guide cylinder and contacting the pushing mechanism. The upper surface of the structure allows it to slide down inside the guide cylinder, which in turn allows the pushing end of the pushing mechanism to be pushed out of the guide rail groove. The pushing mechanism, which slides out of the guide rail groove, presses against the inner wall of the insertion port of the fixture plate, thereby locking the fixture plate to the outer surface of the insertion column. This realizes the fixture plate replacement operation. The design of using wing bolts and pushing mechanism allows the operator to quickly loosen and remove the fixture plate by rotating the wing bolts, then insert a new fixture plate, and then tighten the wing bolts to fix it. This process does not require special tools or complicated operating steps, thus greatly shortening the fixture plate replacement time and improving the overall efficiency and flexibility of the production line.
[0015] 2. Through the design of the guide plate, limiting block, connecting arm, clamping block, and spring, when replacing the jig plate, the wing bolt can be unscrewed from the threaded hole of the insert post. This releases the threaded part of the wing bolt from the guide cylinder, thus relieving the pushing force on the jig plate. The jig plate, through the limiting block and the spring, is then pushed upwards. This causes the jig plate to move the sliding posts on both sides of the connecting arm in the inclined groove of the clamping block. Since the connecting arm moves the sliding posts vertically, the upward movement of the connecting arm and the sliding block in the inclined groove applies a pull-back force to the clamping block, causing it to disengage from the pressure on the inner wall of the jig plate's insert opening. This allows the operator to pull the jig plate out from the outer surface of the insert post, and then... The fixture disc to be replaced is inserted into the outer surface of the insertion post. Then, the operator can screw the wing bolt back into the threaded hole, and simultaneously insert the threaded part of the wing bolt into the guide tube, pressing against the upper surface of the fixture disc and allowing it to slide down within the guide tube. This causes the connecting arm of the fixture disc to drive the sliding posts on both sides to slide down in the inclined slide groove, thereby pushing the clamping block out of the guide rail groove. The clamping block that slides out of the guide rail groove presses against the inner wall of the insertion port of the fixture disc, thus locking the fixture disc onto the outer surface of the insertion post. This completes the fixture disc replacement operation, and the entire process does not require special tools or complicated operating procedures, thereby significantly shortening the fixture disc replacement time and improving the overall efficiency and flexibility of the production line.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 This utility model provides a technical solution:
[0023] like Figures 1-2 As shown, a quick-change fixture for an LCD feeding machine includes: a mounting frame 1, a motor 102 fixedly mounted on the lower surface of the mounting frame 1, the output shaft of the motor 102 extending through to the upper surface of the mounting frame 1 and having an insertion post 101 fixedly mounted at its end, a fixture disc 103 slidably inserted into the outer surface of the insertion post 101, and threaded holes 106 and guide cylinders 105 respectively provided in the upper and lower halves of the insertion post 101. The threaded hole 106 is connected to the guide cylinder 105. The push mechanism 2 is slidably installed in the guide cylinder 105. The push end of the push mechanism 2 slides in the guide groove 107. The guide groove 107 is opened in the lower half of the outer surface of the insertion post 101 and is connected to the guide cylinder 105. The push mechanism 2 can slide out from the guide groove 107 and press against the inner wall of the insertion port of the fixture disk 103, so that the fixture disk 103 can be locked at the outer surface of the insertion post 101.
[0024] A wing bolt 104 is installed in the threaded hole 106 of the insert post 101, so that the threaded part of the wing bolt 104 can be threaded through into the guide cylinder 105 and touch the upper surface of the pushing mechanism 2.
[0025] Through the design of the insert post 101, motor 102, jig disc 103, wing bolt 104, and pushing mechanism 2, when replacing the jig disc 103, the wing bolt 104 can be unscrewed from the threaded hole 106 of the insert post 101, allowing the threaded portion of the wing bolt 104 to unscrew from the guide cylinder 105, thereby releasing the pushing force on the pushing mechanism 2. This allows the pushing end of the pushing mechanism 2 to slide into the guide groove 107, releasing the pressure on the inner wall of the insert diameter of the jig disc 103. This allows the worker to pull the jig disc 103 out from the outer surface of the insert post 101, and then insert the replacement jig disc 103 into the outer surface of the insert post 101. The worker can then screw the wing bolt 104 back into the threaded hole 106, simultaneously inserting the threaded portion of the wing bolt 104 into the guide cylinder 105. The pusher 5 contacts the upper surface of the pushing mechanism 2, causing it to slide down inside the guide cylinder 105. This pusher end of the pushing mechanism 2 is then pushed out of the guide groove 107. The pushing mechanism 2, which has slid out of the guide groove 107, presses against the inner wall of the insertion port of the fixture disk 103, thereby locking the fixture disk 103 to the outer surface of the insertion post 101. This enables the replacement of the fixture disk 103. The design of using the wing bolt 104 and the pushing mechanism 2 allows the operator to quickly loosen and remove the fixture disk 103 by rotating the wing bolt 104. Then, a new fixture disk 103 is inserted and fixed by tightening the wing bolt 104. This process does not require special tools or complicated operating steps, thus significantly shortening the replacement time of the fixture disk 103 and improving the overall efficiency and flexibility of the production line.
[0026] like Figures 3-4 As shown, the pushing mechanism 2 includes a guide plate 201, which slides inside the guide cylinder 105. Connecting arms 203 are fixedly installed at both ends of the outer surface of the guide plate 201. Sliding columns are fixedly installed on both sides of the connecting arms 203. The connecting arms 203 slide into the pressing block 204 and slide through the sliding columns on both sides into the inclined sliding grooves 205 opened on both sides inside the pressing block 204. The pressing block 204 slides in the guide rail groove 107.
[0027] This allows the guide plate 201 to slide down inside the guide cylinder 105 under the pressure of the threaded portion of the wing bolt 104. As the guide plate 201 slides down, it drives the connecting arms 203 at both ends to slide down inside the clamping block 204. This allows the connecting arms 203 to drive the sliding columns on both sides to slide and push the clamping block 204 in the inclined slide groove 205. As a result, the clamping block 204 slides outward in the guide rail groove 107 and presses against the inner wall of the insertion port of the fixture plate 103.
[0028] Limiting blocks 202 are fixedly installed on both sides of the guide plate 201. The limiting blocks 202 are slidably installed in the limiting grooves 108, which are opened on both sides of the guide cylinder 105.
[0029] A spring 206 is provided inside the limiting groove 108. The upper and lower ends of the spring 206 are fixedly connected to the lower surface of the limiting groove 108 and the lower surface of the limiting block 202, respectively.
[0030] Through the design of the guide plate 201, limiting block 202, connecting arm 203, clamping block 204, and spring 206, when replacing the jig plate 103, the wing bolt 104 can be unscrewed from the threaded hole 106 of the insert post 101, thus releasing the pushing force on the jig plate 103. The jig plate 103 will then be pushed upwards by the spring 206 through the limiting block 202, thereby allowing the jig plate 103 to be replaced. The jig disc 103 drives the sliding columns on both sides of the connecting arm 203 to slide in the inclined groove 205 of the clamping block 204. Since the connecting arm 203 drives the sliding columns to slide vertically, the connecting arm 203 drives the sliding block to slide upward in the inclined groove 205, which will exert a pull-back force on the clamping block 204. This will cause the clamping block 204 to disengage from the pressure on the inner wall of the insertion port of the jig disc 103, allowing the operator to lift the jig disc 103 from the outer surface of the insertion column 101. After pulling out the fixture, the replacement fixture disc 103 can be inserted into the outer surface of the insertion post 101. Then, the operator can screw the wing bolt 104 back into the threaded hole 106, simultaneously inserting the threaded portion of the wing bolt 104 into the guide cylinder 105 and pressing against the upper surface of the fixture disc 103, allowing it to slide down within the guide cylinder 105. This allows the connecting arm 203 of the fixture disc 103 to drive the sliding posts on both sides to slide down within the inclined groove 205, thereby enabling... The clamping block 204 is pushed out of the guide rail groove 107 and slides out. The clamping block 204 that slides out of the guide rail groove 107 will press against the inner wall of the insertion port of the fixture disk 103, thereby locking the fixture disk 103 to the outer surface of the insertion post 101. This realizes the replacement operation of the fixture disk 103. The whole process does not require special tools or complicated operation steps, thus greatly shortening the replacement time of the fixture disk 103 and improving the overall efficiency and flexibility of the production line.
[0031] Based on the above technical solution, the working steps of this solution are summarized as follows: When replacing the jig disc 103, the wing bolt 104 can be unscrewed from the threaded hole 106 of the insert post 101, thereby releasing the push on the jig disc 103. The jig disc 103 will then be pushed upward by the spring 206 through the limiting block 202, which will cause the jig disc 103 to drive the sliding posts on both sides of the connecting arm 203 to slide in the inclined groove 205 of the pressure block 204. Since the connecting arm 203 drives the sliding posts to slide vertically, the connecting arm 203 will exert a pull force on the pressure block 204 during the upward sliding of the sliding block in the inclined groove 205. This will cause the pressure block 204 to disengage from the pressure on the inner wall of the insert diameter of the jig disc 103, thus allowing the jig disc 103 to be supplied with the insert. The worker pulls the jig disc 103 off the outer surface of the insertion post 101, and then inserts the jig disc 103 to be replaced onto the outer surface of the insertion post 101. The worker can then screw the wing bolt 104 into the threaded hole 106, and insert the threaded part of the wing bolt 104 into the guide cylinder 105, which presses against the upper surface of the jig disc 103, allowing it to slide down within the guide cylinder 105. This causes the connecting arm 203 of the jig disc 103 to drive the sliding posts on both sides to slide down within the inclined slide groove 205, thereby pushing the clamping block 204 out of the guide rail groove 107. The clamping block 204 that slides out of the guide rail groove 107 presses against the inner wall of the insertion port of the jig disc 103, thus locking the jig disc 103 onto the outer surface of the insertion post 101, thereby completing the jig disc 103 replacement operation.
[0032] In summary, by rotating the wing bolt 104, the operator can quickly loosen and remove the jig disc 103, then insert a new jig disc 103, and then tighten the wing bolt 104 to secure it. This process does not require special tools or complicated operating steps, thus significantly shortening the jig disc 103 replacement time and improving the overall efficiency and flexibility of the production line.
