Description

Technical Field

[0001] The utility model belongs to the technical field of frame jigs, in particular to a frame clamping jig and a frame opening machine. Background Art

[0002] Thin panels made of flexible substrates are currently very important components in the 3C electronics industry. Due to their lack of rigidity, thin panels are easily bent, deformed, or damaged. Therefore, during the processing of thin panels, they must be placed in a clamping jig. The rigid structure of the clamping jig protects the thin panels from deformation and damage during transportation and processing.

[0003] For existing frame clamping jig structures, reference can be made to patent CN204528764U, "A frame clamping jig, frame opening mechanism, and plate retracting and unfolding device having the same." Existing frame clamping jigs, including those in this patent, only clamp one pair of side walls of a thin plate. Thin plates are prone to bending due to their inherent structural characteristics. Therefore, when a thin plate is placed in the frame clamping jig, the other pair of side walls lack support, causing the plate to bend. This necessitates additional manual or other equipment assistance.

[0004] Therefore, a rectangular clamping frame jig came into being. At the same time, in order to ensure that the thin plates after being clamped will not bend due to external interference during transportation, the clamping force of the clamping frame jig needs to be increased. Therefore, the difficulty of opening the frame manually is multiplied. Before the structure disclosed in the above patent is automatically opened, it is necessary to use a holding pneumatic cylinder and a snap-on pneumatic cylinder to position the inner and outer edges of the clamping frame jig respectively, and then use the holding mechanism to drive the screwdriver actuator to move upward, and finally rotate the screwdriver actuator to unlock the clamping frame jig to open the clamping frame jig. The overall operation is complicated and difficult to control.

[0005] In order to solve the above problems, designing a frame clamping fixture and a frame opening machine is an important technical problem that those skilled in the art need to solve. Utility Model Content

[0029] The objectives, advantages, and features of the present invention are illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of the application of the technical solutions of the present invention. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

[0031] A clamping frame fixture for clamping thin plates. Figures 1 to 2 The base 11 is formed in one piece and the clamping seat 12 is split and pivotally arranged on the base 11. In the present invention, the base 11 is preferably designed to be rectangular, and a group of through holes 110 are formed on each side, and the through holes 110 are spaced apart from the inner edge of the base 11; the edge of the thin plate is located between the through holes 110 and the inner edge of the base 11. In other embodiments, the shape of the base 11 can also be polygonal or circular, etc., and only the rectangular structure is used as an example for explanation. Under normal circumstances, Figure 2 As shown, the clamping seat 12 covers the base 11, and the inner edge of the clamping seat 12 is flush with the base 11 to clamp the thin plate. Figure 1 As shown, the clamping seat 12 is flipped upward relative to the base 11 by an external force, opening the clamping frame jig to facilitate placement or removal of the thin panel. The thin panel is placed on the base of the clamping frame jig and is clamped and fixed on all sides by the clamping seat to ensure the flatness of the thin panel and its stability during transportation.

[0032] Furthermore, the width of the base 11 is greater than the width of the clamping seat 12, and the two are connected by a hinge; that is, the outer edge of the base 11 protrudes from the outer edge of the clamping seat 12, making it convenient for external equipment to act on the outer edge of the base 11 to fix the position of the clamping frame fixture. An elastic strip 121 is embedded in the interior of the clamping seat 12, and the bottom of the elastic strip 121 protrudes from the bottom surface of the clamping seat 12; and the elastic strip 121 is close to the inner edge of the clamping seat 12; under normal circumstances, the elastic strip 121 is located on the outside of the through hole 110. Providing the elastic strip 121 on the clamping seat 12 can reduce the indentation caused to the thin plate during clamping, and at the same time play a shock-absorbing and buffering role during clamping, reducing damage to the thin plate and ensuring its yield rate.

[0033] like Figures 2 to 4 As shown, the utility model also discloses a frame opening machine, including a frame 2 for supporting the base 11. A holding mechanism 3 and a frame opening mechanism 4 are provided on the frame 2. The holding mechanism 3 is provided at the edge of the frame 2, and applies downward pressure to the outer edge of the base 11 when in use. The frame opening mechanism 4 is provided below the frame 2. When in use, the lifting rod 43 in the frame opening mechanism 4 passes through the base 11 and applies an upward force to the clamping seat 12 until the clamping seat 12 is perpendicular to the base 11. By applying forces in opposite directions to the base and the clamping seat of the frame clamping jig respectively through the holding mechanism and the frame opening mechanism, automatic frame opening action is realized, which reduces labor cost benefits and improves work efficiency.

[0034] like Figure 6 As shown, the pressing mechanism 3 includes a first cylinder 31 provided on a mounting plate 30 and a pressure bar 32 connected to the output end of the first cylinder 31. Figure 4 and Figure 5 As shown, the pressure strip 32 is pivotally connected to the frame 2; specifically, the present invention preferably connects the frame 2 and the pressure strip 32 via a hinge. Because the pressure strip 32 needs to rotate about the hinge, the present invention preferably arranges the first cylinder 31 at an angle. Furthermore, to reduce damage to the base 11 caused by the pressure strip 32, a rubber pad 321 is preferably provided on the lower surface of the output end of the pressure strip 32. Under normal conditions, the rubber pad 321 abuts against the outer edge upper surface of the base 11; when in use, the pressure strip 32 is driven to flip by the first cylinder 31.

[0035] Combine Figure 4 and Figure 6As shown, the frame opening mechanism 4 includes an electric cylinder 41 arranged directly below the frame 2, a lifting frame 42 arranged at the output end of the electric cylinder 41, and a lifting rod 43 arranged on the lifting frame 42. The electric cylinder 41 can also be replaced by a known structure such as an air cylinder, an oil cylinder, or a linear motor. Here, only the electric cylinder is used as an example for explanation. The end of the lifting frame 42 is fixedly connected to the frame 2. In use, the electric cylinder 41 drives the lifting frame 42 and the frame 2 to move upward, and at the same time, the lifting rod 43 passes through the frame 2 and the through hole 110 in sequence, and the lifting rod 43 applies an upward force to the clamping seat 12 to open the clamping frame fixture. In addition, the lifting frame 42 will contact the lower surface of the thin plate during the movement, and drive the thin plate to move upward to disengage from the base 11 so that it can be taken out of the clamping frame fixture.

[0036] like Figure 6 As shown, a limit assembly 5 is provided on the inner wall of the lifting frame 42. The limit assembly 5 includes a second cylinder 51 provided on the mounting frame 50 and a limit rod 52 driven by the second cylinder 51 to lift and lower. The output end of the second cylinder 51 is fixed by a connecting plate 53, and the limit rod 52 is fixed on the connecting plate 53; the limit rod 52 passes through the frame 2 and is located at the inner edge of the base 11. Furthermore, two limit rods 52 are provided on each side wall of the frame 42; and the two limit rods 52 are spaced apart on the connecting plate 53. A connecting rod is also provided between the connecting plate 53 and the mounting frame 50, and the connecting rod is located on both sides of the output shaft of the second cylinder 51. The connecting rod increases the connection reliability between the connecting plate 53 and the mounting frame 50, while sharing the pressure of the second cylinder 51 and extending the service life of the second cylinder 51.

[0037] To ensure that all the limiting rods 52 rise and fall at the same frequency and height, the present invention preferably connects the bottom ends of the two adjacent side walls of the frame 42 via a fixed plate 20. A telescopic rod 21 is connected to the bottom end of the fixed plate 20, and the telescopic rod 21 extends and retracts synchronously with the electric cylinder 41. The holding mechanism, the frame opening mechanism, and the limiting assembly cooperate. The holding mechanism limits the vertical position of the frame clamping jig and applies force, while the limiting rod of the limiting assembly limits the horizontal position of the frame clamping jig. The holding mechanism and the limiting assembly define the position of the frame clamping jig and ensure the stability of the frame opening process. The frame opening mechanism then automatically opens the frame, saving time and effort.

[0038] There are many implementation methods for the present utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present utility model.
