Description

Technical Field

[0001] This utility model relates to the field of processing fixture technology, and in particular to a fixing fixture. Background Technology

[0002] During the processing of products such as mobile phone screens, vacuum adsorption platforms are typically used to adsorb and fix them for processing. To prevent damage caused by the sudden failure of the vacuum adsorption platform, a clamp is often installed on the vacuum adsorption platform. The clamp and the vacuum adsorption platform can work together to form a secondary fixation of the product. Currently, the clamp is often controlled by a cylinder to move closer to or away from the product. However, the clamp driven by the cylinder has excessive instantaneous pressure when it first contacts the product, which can easily damage the product, especially fragile products such as mobile phone screens.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0051] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between 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.

[0052] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0053] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0054] This embodiment aims to provide a fixing fixture for securing a product to avoid damage to the product during clamping. In this embodiment, a mobile phone screen is used as an example. In some other feasible embodiments, the product can also be other products to be processed, and no specific limitation is made here.

[0055] Specifically, please refer to Figures 1 to 4 The fixing fixture includes a base 1, a mounting base 2, a clamp 3, a first unlocking mechanism 4, and a first compression spring 5. The base 1 is used to support the product and is provided with a vacuum suction hole 11, which is connected to an external negative pressure source for adsorbing and fixing the product. The mounting base 2 is disposed on the side wall of the base 1. The clamp 3 is slidably disposed on the mounting base 2 and has a clamping state for clamping the product and an unlocking state for separating from the product. The first unlocking mechanism 4 is connected to the clamp 3 and has a force-applying state for applying force to the clamp 3, so that the clamp 3 slides away from the base 1 and switches from the clamping state to the unlocking state, and a release state for stopping the application of force to the clamp 3. The first compression spring 5 is compressed between the clamp 3 and the mounting base 2 and has elastic potential energy to recover deformation when the first unlocking mechanism 4 is in the released state and to make the clamp 3 slide in the direction close to the base 1, so that the clamp 3 returns from the unlocking state to the clamping state.

[0056] Understandably, before placing the product on the base 1, the first unlocking mechanism 4 applies force to the chuck 3 to keep it in the unlocked state. After the product is placed, it is held in place by vacuum suction holes 11. Then, the first unlocking mechanism 4 stops applying force to the chuck 3, and the chuck 3 returns to the clamping state under the elastic potential energy of the first compression spring 5. Due to the elasticity of the first compression spring 5, it deforms when the chuck initially contacts the product, thus preventing excessive instantaneous pressure and avoiding damage to the product. Furthermore, when the cylinder is used as the driving structure to keep the chuck 3 in contact with the product, the piston rod is always extended, which can easily cause abnormal pressure on the piston, connecting rod, crankshaft, and other components inside the cylinder, resulting in deformation, breakage, or wear. However, when the first compression spring 5 is used as the driving structure, its elastic potential energy allows the chuck 3 to remain in contact with the product, which is more stable, lower in cost, and has a longer service life.

[0057] It should be noted that, depending on the different processing technology, multiple bases 1 can be integrated on the same bracket. In this embodiment, two are preferred, and each base 1 is provided with a mounting seat 2, a clamp 3, a first unlocking mechanism 4, and a first compression spring 5. In some other feasible embodiments, the number of bases 1 can be selected according to actual production needs, and no specific limitation is made here.

[0058] In this embodiment, the chuck 3 includes a sliding part 31, a connecting part 32, and a clamping part 33. The sliding part 31 is obliquely and slidably disposed inside the mounting base 2 in a direction away from the base 1. One end of the connecting part 32 is connected to the sliding part 31 and is disposed vertically outside the mounting base 2. The clamping part 33 is disposed at the other end of the connecting part 32 and extends parallel to the top of the base 1. It can be understood that under the action of the first unlocking mechanism 4, the connecting part 32 can be pushed to slide, thereby driving the connecting part 32 and the clamping part 33 to move in a direction away from the base 1, thereby enabling the chuck 3 to be in an unlocked state, so that the operator can place the product on the base 1 or remove the product from the base 1.

[0059] Furthermore, the sliding part 31 is provided with a first receiving groove 311 inside, the length direction of the first receiving groove 311 is consistent with the sliding direction of the sliding part 31; the mounting base 2 is provided with a limiting block 23, the limiting block 23 is arranged opposite to the groove opening of the first receiving groove 311, and a gap is provided between the two; the first compression spring 5 is disposed in the first receiving groove 311, and its two ends abut against the bottom of the groove of the first receiving groove 311 and the limiting block 23 respectively. It can be understood that during the process of the clamp 3 switching from the clamping state to the unlocking state, under the force applied to the clamp 3 by the first unlocking mechanism 4, the sliding part 31 can gradually move closer to the limiting block 23. During this process, the first compression spring 5 can gradually compress, and the pressing part gradually moves away from the base 1. When clamping the product, when the first unlocking mechanism 4 stops applying force to the clamp 3, the sliding part 31 can slide back to the initial position under the action of the first compression spring 5, that is, the clamp can be restored from the unlocking state to the clamping state.

[0060] In this embodiment, the first unlocking mechanism 4 includes a first unlocking block 41 and a first unlocking cylinder. The first unlocking block 41 is disposed below the mounting base 2 and faces one end of the clamp 3. The first unlocking cylinder is connected to the first unlocking block 41 and is used to drive the first unlocking block 41 closer to or further away from the clamp 3, so that the first unlocking block 41 switches between a force-applying state and a release state. It can be understood that under the action of the first unlocking cylinder, the first unlocking block 41 can be driven to move closer to the sliding part 31 and push the sliding part 31 to move, thereby driving the clamp 33 to move away from the base 1, so as to place or remove the product. Then the first unlocking cylinder resets, driving the first unlocking block 41 to move away from the sliding part 31. The sliding part 31 can be reset to its initial position under the action of the first compression spring 5 and can be maintained in a state of contact with the product.

[0061] Specifically, in this embodiment, the mounting base 2 is provided with a through groove 21 that is adapted to slide the sliding part 31, and the through groove 21 is inclined in the direction away from the base 1. When the chuck 3 is in the clamping state, the end of the sliding part 31 away from the chuck 3 can extend to the outside of the through groove 21 and face the first unlocking block 41. Under the action of the connecting part 32, the chuck 3 can be prevented from separating from the through groove 21. Under the action of the first unlocking cylinder, the connecting part 32 can be driven to move towards the limiting block 23 so that the chuck 3 can switch from the unlocked state to the separated state.

[0062] Furthermore, multiple mounting bases 2 are evenly distributed along the circumference of the base 1, and each mounting base 2 has a slidably mounted clamp 3. This arrangement ensures that the product can be clamped at different positions, thereby guaranteeing the stability of the product when it is fixed. In addition, the first unlocking mechanism 4 also includes an unlocking platform 42, which is disposed between the first unlocking block 41 and the first unlocking cylinder. The unlocking platform 42 is provided with multiple first unlocking blocks 41, and each of the multiple first unlocking blocks 41 is correspondingly arranged with a multiple clamp 3. It can be understood that, with the cooperation of the unlocking platform 42 and the first unlocking cylinder, all the clamps 3 can be lifted simultaneously, thereby ensuring the consistency of the working state of each clamp 3 and reducing production costs.

[0063] In this embodiment, the fixing fixture further includes a locking mechanism 6 and a second unlocking mechanism 7. The locking mechanism 6 is disposed on the mounting base 2 and is used to lock the chuck 3 when the chuck 3 is in the unlocked state. The second unlocking mechanism 7 is connected to the locking mechanism 6 and is used to release the locking mechanism 6 from locking the chuck 3. It can be understood that when the chuck 3 is in the unlocked state, the locking mechanism 6 can lock the chuck 3 to keep the chuck 3 in the unlocked state. During this process, the first unlocking cylinder does not need to remain in the extended state, thereby improving the service life of the first unlocking cylinder.

[0064] The locking mechanism 6 includes a second compression spring 61 and a locking block 62. The locking block 62 is slidably disposed inside the mounting base 2, and the second compression spring 61 is compressed between the base 1 and the locking block 62 to keep the locking block 62 in contact with the chuck 3. The chuck 3 is provided with a locking groove 312 adapted to lock the locking block 62. The locking groove 312 is used to lock the locking block 62 when the chuck 3 is in the unlocked state. It can be understood that the second compression spring 61 can keep the locking block 62 in contact with the chuck 3. During the movement of the sliding part 31, the locking block 62 can slide on the sliding part 31 and engage with the locking groove 312 on the sliding part 31 under the action of the second compression spring 61 to complete the locking of the chuck 3.

[0065] Specifically, in this embodiment, the mounting base 2 is provided with a second receiving groove 22 inside. The second compression spring 61 is compressed and disposed on the bottom of the second receiving groove 22 and the side of the locking block 62 away from the sliding part 31. The locking block 62 is provided with an opening on the side facing the sliding part 31. The opening is adapted to slide with the sliding part 31. During the sliding process, the opening can enter the locking groove 312 under the action of the second compression spring 61 to complete the locking of the chuck 3.

[0066] Furthermore, the second unlocking mechanism 7 includes a second unlocking block 71 and a second unlocking cylinder. The second unlocking block 71 is located on the side of the clamp 3 opposite to the locking block 62 and directly opposite the locking block 62. The second unlocking cylinder is connected to the second unlocking block 71 and is used to push the locking block 62 away from the locking groove 312. Under the action of the second unlocking cylinder, the second unlocking block 71 can be driven to abut against the locking block 62, and the locking block 62 can be pushed to move away from the sliding part 31, thereby disengaging the locking block 62 from the locking groove 312. Under the action of the first compression spring 5, the clamp 3 can be driven to return from the unlocked state to the locked state. At this time, the locking block 62 remains in abutment against the sliding part 31 under the action of the second compression spring 61, facilitating locking in the next cycle.

[0067] Furthermore, when multiple mounting bases 2 are provided, each mounting base 2 is equipped with a clamp 3, and each mounting base 2 is equipped with a corresponding locking mechanism 6. To facilitate simultaneous unlocking of the locking mechanism 6, the second unlocking mechanism 7 also includes an unlocking frame 72. The unlocking frame 72 is located between the second unlocking block 71 and the second unlocking cylinder, and multiple second unlocking blocks 71 are provided on the unlocking frame 72, with each of the multiple second unlocking blocks 71 corresponding to one of the multiple clamps 3. It can be understood that, with the cooperation of the unlocking frame 72 and the second unlocking cylinder, all locking blocks 62 can be lifted simultaneously, thereby ensuring that each clamp 3 can be released simultaneously, thus ensuring the consistency of the working state of each clamp 3, and also reducing production costs. In addition, the unlocking frame 72 is sleeved on the outside of the unlocking platform 42, which reduces the height of the entire fixing fixture.

[0068] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
