Description

Technical Field

[0001] This utility model relates to the field of ultra-thin product clamping structures, specifically a dual elastic clamping mechanism. Background Technology

[0002] For ultra-thin and fragile products, existing technologies mostly use rigid clamping or single elastic clamping, which results in a high breakage rate during robot or worker clamping. After clamping, the movement during handling is very slow, which seriously affects production efficiency and also results in a high breakage rate. After clamping, the breakage rate is high during subsequent processing due to movement, heating, bending, etc. The replacement and maintenance caused by changing the clamping mechanism and wear and tear is troublesome. Utility Model Content

[0003] The purpose of this invention is to provide a dual-elastic clamping mechanism that can autonomously adapt to products with different clamping forces, is not easily damaged during transportation, and is convenient for later replacement and maintenance. This solves the problem of high product breakage rates during traditional clamping, handling, and processing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dual elastic clamping mechanism, comprising:

[0005] A fixture frame, wherein a placement position is provided on the fixture frame;

[0006] The elastic clamping element is mounted on the fixture frame and located above the fixture frame;

[0007] The elastic clamping component includes a mounting base, a swing arm, a rotating shaft, and a torsion spring. The torsion spring is sleeved on the rotating shaft and supported between the swing arm and the mounting base.

[0008] The swing arm is provided with an elastic pressure plate, and the elastic pressure plate is provided with elastic contact points.

[0009] As a further improvement to the above technical solution:

[0010] The elastic clamping member also includes an elastic pad, which is installed in the placement position.

[0011] The inner edge of the fixture frame is recessed to form a placement position, and the fixture frame is provided with several recessed grooves for accommodating elastic clamping components.

[0012] The elastic pad has a mounting base on one side, and the mounting base has a insertion hole. An elastic glass bead is placed in the insertion hole. The elastic pad is inserted into the insertion hole and positioned by the elastic glass bead.

[0013] It also includes a drive frame, and the drive frame and the fixture frame are provided with positioning pins and positioning holes so that the drive frame and the fixture frame can cooperate; the drive frame is provided with a number of firing elements, and the firing elements include contact rods and actuators. The actuators drive the contact rods downward, thereby driving the swing arm to move.

[0014] The actuator includes a plurality of rotating cams mounted on a drive frame, a grooved wheel on the contact rod that cooperates with the rotating cams, a timing pulley above the rotating cams, and a timing drive belt between the timing pulleys.

[0015] The synchronous pulley is equipped with a driver, which can be a manual drive structure or an electric drive structure, and is used to drive the synchronous pulley to rotate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Dual Elastic Protection: A dual elastic clamping structure is formed through the combined action of a torsion spring and an elastic pressure plate. The torsion spring provides a wide range of clamping forces, while the elastic pressure plate offers more precise and sensitive clamping force adjustment. This design can autonomously adapt to products with different clamping forces. Even if the clamping force is less than that of the torsion spring, the deformation of the elastic pressure plate can compensate, ensuring that the product is firmly and safely clamped.

[0018] Wide applicability: It can be used to clamp various ultra-thin and fragile sheet materials, such as glass, copper, aluminum, and plexiglass. The dimensions of the fixture frame and placement position can be customized according to product requirements, and the shape can also be designed as round, square, etc., making it extremely versatile.

[0019] Comprehensive product protection reduces breakage rates: The recessed inner edge of the fixture frame creates a placement area, effectively preventing damage to the product's corners and edges during placement and clamping. The elastic contacts are made of soft materials such as silicone, ensuring they won't scratch or affect the product surface upon contact. The elastic pads are also made of soft materials like rubber or silicone, providing cushioning protection for the product's bottom.

[0020] Quick clamping: The drive frame and fixture frame are engaged by locating pins and locating holes to ensure precise positioning. The driver moves the synchronous pulley and rotating cam, allowing for easy opening and closing of the elastic clamping components, facilitating product placement and removal.

[0021] Easy to maintain: The elastic pressure plate adopts a quick-release structure, allowing for easy plug-and-play installation and replacement simply by tightening or loosening the screws on the swing arm, making maintenance very convenient. The elastic pad also allows for quick installation and replacement via the mounting base and elastic glass beads, facilitating repair and replacement.

[0022] Compact and efficient: The drive mechanism adopts a structure of synchronous belt pulley and rotating cam, which can realize the up and down movement of the contact rod without a large operating range. It is compact and highly efficient.

[0023] In summary, the dual elastic clamping mechanism of this invention can autonomously adapt to products with different clamping forces, is not easily damaged during movement, heating, and bending, and is convenient for later replacement and maintenance. It solves the problem of high product breakage rate during traditional clamping, handling, and processing. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] 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.

[0040] like Figure 1 and Figure 2 As shown, the dual elastic clamping mechanism of this embodiment includes:

[0041] The fixture frame 1 has a placement position 11. In this embodiment, the inner edge of the fixture frame 1 is recessed to form the placement position 11. The recessed design can prevent the corners and edges from being bumped.

[0042] The jig frame 1 can clamp ultra-thin and fragile sheet materials (glass, copper, aluminum, plexiglass, etc.). Its shape can be round, square, etc., and the shape can be designed arbitrarily according to product requirements.

[0043] The elastic clamping member 2 is installed on the fixture frame 1 and located above the fixture frame 1. In this embodiment, the fixture frame 1 is provided with several recessed grooves for accommodating the elastic clamping member 2. The recessed design of the elastic clamping member 2 avoids surface protrusion and facilitates placement and handling. Several elastic clamping members 2 are arranged on the fixture frame 1. The bottom surface of the fragile product 100 is placed in the placement position 11 and positioned and fixed by the elastic clamping members 2, which ensures the safety of the fragile product 100.

[0044] The bottom surface of the product contacts the pad, the sides of the product contact the side steps of the surrounding pads (with reserved clamping gap), and the top surface of the product contacts the contact points installed on the spring.

[0045] like Figure 3 and Figure 4 As shown, the elastic clamping component 2 includes a mounting base 21, a swing arm 22, a rotating shaft 23, and a torsion spring 24. The torsion spring 24 is sleeved on the rotating shaft 23 and supported between the swing arm 22 and the mounting base 21. An elastic pressure plate 25 is provided on the swing arm 22, and an elastic contact 26 is provided on the elastic pressure plate 25. Under the action of external force, the swing arm 22 will overcome the force of the torsion spring 24 and rotate upward, driving the elastic pressure plate 25 to move and be in an open feeding state. After feeding is completed, the external force is released, and under the action of the torsion spring 24, the swing arm 22 rotates downward and presses against the fragile product 100. The elastic pressure plate 25 is made of elastic metal material and is combined with the torsion spring 24 to form a double elastic combination. The elastic contact 26 is made of soft material such as silicone and is installed at the front of the elastic pressure plate 25 for contact with the fragile product 100. The elastic pressure plate 25 can be formed by stacking multiple elastic plates. The elastic pressure plate 25 adopts a quick-release structure. Simply loosening or tightening the screws on the swing arm 22 allows for the plug-in installation and replacement of the spring plate. When replacing, only one worn or contaminated spring plate needs to be replaced.

[0046] To prevent bottom damage, an elastic pad layer can be provided on the placement position 11. Since this pad covers a large area and is inconvenient to maintain, in one embodiment, the elastic clamping member 2 further includes an elastic pad 27, which is installed on the placement position 11. The elastic pad 27 is made of a soft material such as rubber or silicone.

[0047] like Figure 5As shown, for further ease of use, a mounting base 28 is provided on one side of the elastic pad 27. The mounting base 28 has an insertion hole, and an elastic glass bead 29 is placed in the insertion hole. The elastic pad 27 is inserted into the insertion hole and positioned by the elastic glass bead 29. The mounting base 28 is fixed to the sink groove with bolts, which can realize the quick installation of the elastic pad 27 and facilitate the replacement of the elastic pad 27.

[0048] like Figure 6 and Figure 7 As shown, since there are many elastic clamping parts 2 in this embodiment, the normal operation of the elastic clamping parts 2 cannot be guaranteed without a dedicated starting mechanism. Therefore, this embodiment discloses a dedicated starting mechanism. The starting mechanism includes a drive frame 3. The drive frame 3 and the fixture frame 1 are provided with positioning pins and positioning holes (not shown in the figure, the positioning pins can be installed according to the actual design) so that the drive frame 3 and the fixture frame 1 cooperate. That is to say, the drive frame 3 is connected to the fixture frame 1. The drive frame 3 and the elastic clamping parts 2 are used together. The elastic clamping parts 2 are opened by the drive frame 3 to perform material feeding and material picking.

[0049] like Figures 7 to 11 As shown, the drive frame 3 is equipped with several firing elements 4. Each firing element 4 includes a contact rod 41 and an actuator 42. The actuator 42 drives the contact rod 41 downward, thereby moving the swing arm 22. In this embodiment, the contact rod 41 is used to contact the swing arm 22. The actuator 42 drives the contact rod 41 downward, causing the swing arm 22 to rotate upward. The actuator 42 can be a cylinder, a linear module, etc., to enable the downward and upward movement of the contact rod 41.

[0050] This embodiment provides an actuator 42, which includes a plurality of rotating cams 421 disposed on a drive frame 3. A grooved wheel that cooperates with the rotating cams 421 is disposed on a contact rod 41. A synchronous pulley 422 is disposed above the rotating cams 421, and a synchronous drive belt 423 is disposed between the synchronous pulleys 422. The rotating cams 421 have an inclined structure, and the rotation of the rotating cams 421 drives the contact rods 41 to move up and down.

[0051] A driver 424 is installed on the synchronous pulley 422. The driver can be a manual drive or an electric drive, used to drive the synchronous pulley 422 to rotate. The manual drive is a crank handle, which drives the synchronous pulley 422 to rotate. Since a cam-grooved pulley is used, a large operating range is not required, so one rotation is enough to achieve movement.

[0052] The working principle of this embodiment:

[0053] Before use, according to the size of the fragile product 100 to be placed, make a corresponding jig frame 1, and process the placement position 11 and the sinking groove. The size of the placement position 11 should be larger than the size of the fragile product 100 (usually 1-5mm). Install the elastic clamping element in the sinking groove with bolts, and install the mounting base 28 into the sinking groove. Select a suitable elastic pad 27 and insert it into the insertion hole, and lock it with the elastic glass ball 29.

[0054] The drive frame 3 is manufactured according to the structure of the fixture frame 1. It is mainly designed according to the position of the swing arm 22 so that the contact rod 41 of the drive frame can contact the swing arm 22.

[0055] After the equipment is installed and debugged, the driver 424 drives one of the synchronous pulleys 422 to rotate, which causes the synchronous drive belt 423 to move and drive all the synchronous pulleys 422 to rotate. In order to ensure normal operation, a corresponding tensioning wheel should be set to ensure the tension of the synchronous drive belt 423 (to ensure that the synchronous pulleys 422 can run synchronously). The synchronous pulley 422 drives the rotating cam 421 to rotate, which causes the contact rod 41 to move downward. The contact rod 41 is slidably set in the drive frame 3 and can move up and down. The contact rod 41 presses the swing arm 22, which causes the swing arm 22 to rotate upward. The elastic pressure plate 25 moves accordingly, and the fragile product 100 can be put in. After it is put in, the driver 424 reverses and drives the contact rod 41 to move upward through the rotating cam 421, releasing the pressure on the swing arm 22. The swing arm 22 rotates downward under the action of the torsion spring 24, so that the elastic pressure plate 25 holds the fragile product 100.

[0056] This invention features dual elastic clamping, achieved through a combination of spring clamping and spring clip clamping. It can autonomously adapt to products with varying clamping forces. The spring clamping can accommodate a wide range of clamping forces, while the spring clip handles very small and sensitive clamping forces. When the clamping force is less than the spring clamping force, the elastic deformation of the spring clip compensates for this. Contact points are installed at the contact points between the spring clip and the product, protecting the product surface from scratches and damage. Even when the spring clip deforms, the contact points maintain good contact with the product. It is less prone to breakage during movement, heating, and bending: the use of pads and contact points ensures stable product clamping while allowing for slight displacement under vibration and bending conditions, reducing stress concentration and lowering the breakage rate.

[0057] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
