Description

Technical Field

[0001] This invention relates to the field of fixture technology, and in particular to a positioning fixture and a production line using the positioning fixture. Background Technology

[0002] Currently, products such as packaging boxes typically require labels or other operations to be affixed to their exterior before leaving the factory. When affixing labels or performing other operations on the product's exterior, positioning fixtures are needed to hold the product in place so that users can accurately and stably affix labels or perform other operations on the product later.

[0003] However, in the positioning fixtures of related technologies, each clamping block operates independently when clamping the product, requiring the user to sequentially drive each clamping block to gradually clamp the product. This sequential operation is cumbersome, impacting the efficiency of product positioning. Furthermore, the sequential clamping of the product by each block can easily lead to uneven clamping forces on different sides, causing product deformation. Summary of the Invention

[0004] The main objective of this invention is to provide a positioning fixture that improves the efficiency of product positioning while ensuring uniform force on all sides of the product to prevent deformation due to excessive force on one side.

[0005] To achieve the above objectives, the positioning fixture proposed in this invention includes:

[0006] Installation carrier;

[0007] A reference assembly, comprising a first reference component and a second reference component, wherein the first reference assembly and the second reference component are disposed on the mounting carrier;

[0008] A clamping assembly, comprising a first clamping member and a second clamping member, wherein the first clamping member is movably disposed on the mounting carrier along directions approaching and away from the first reference member, and the second clamping member is movably disposed on the mounting carrier along directions approaching and away from the second reference member, and the moving directions of the first clamping member and the moving directions of the second clamping member are set at an angle; and

[0009] A driving component is disposed on the mounting carrier and can simultaneously drive the first clamping member and the second clamping member to move.

[0010] Optionally, the driving assembly includes a first elastic element, a second elastic element, and an operating element; the first elastic element is disposed between the mounting carrier and the first clamping member to drive the first clamping member to move in a direction close to the first reference member; the second elastic element is disposed between the mounting carrier and the second clamping member to drive the second clamping member to move in a direction close to the second reference member; the operating element is movably disposed on the mounting carrier and, when an external force is applied, can drive the first clamping member to move in a direction away from the first reference member, and the second clamping member to move in a direction away from the second reference member;

[0011] Alternatively, the drive assembly includes two motors and two transmission assemblies, both of which are disposed on the mounting carrier; one transmission assembly is drive-connected to one of the two motors and the first clamping member, and the other transmission assembly is drive-connected to the other of the two motors and the second clamping member;

[0012] Alternatively, the drive assembly includes two cylinders, both of which are disposed on the mounting carrier; the first clamping member is connected to one of the two cylinders, and the second clamping member is connected to the other of the two cylinders.

[0013] Optionally, when the drive assembly includes a first elastic element, a second elastic element, and an operating element, the operating element includes a first arm segment and a second arm segment connected to each other and arranged at an angle, and the connection between the first arm segment and the second arm segment is rotatably connected to the mounting carrier.

[0014] The first clamping member is provided with a first abutting part, which abuts against the inner side of the first arm segment; the second clamping member is provided with a second abutting part, which abuts against the outer side of the second arm segment.

[0015] When the end of the second arm segment away from the first arm segment is rotated by an external force, the first arm segment can abut against and drive the first abutting part away from the first reference member, and the second arm segment can abut against and drive the second abutting part away from the second reference member.

[0016] Optionally, the mounting carrier is provided with a grip handle, and the grip handle and the end of the second arm segment away from the first arm segment are arranged opposite each other;

[0017] When the end of the second arm segment away from the first arm segment is rotated toward the grip handle by an external force, the first arm segment and the second arm segment can respectively abut against and drive the first abutting part and the second abutting part.

[0018] Optionally, the mounting carrier is defined to have a first surface and a second surface arranged back to back, and a connecting side connecting the first surface and the second surface;

[0019] The first reference member, the second reference member, the first clamping member, and the second clamping member are disposed on the first surface. The first arm segment and the second arm segment are disposed on the second surface at the end near the first arm segment. The end of the second arm segment away from the first arm segment protrudes from the connecting side. The grip handle is disposed on the connecting side.

[0020] The first abutting portion and the second abutting portion extend to the side of the mounting carrier where the second surface is formed, so as to abut against the inner side of the first arm segment and the outer side of the second arm segment near the end of the first arm segment, respectively.

[0021] Optionally, the mounting carrier includes a main body plate and a mounting plate. The mounting plate includes a first plate and a second plate that are connected to each other and arranged at an angle. The side of the first plate that is away from the second plate is connected to one side of the main body plate.

[0022] The first reference member and the second reference member are disposed on the first surface of the main body plate, and the end of the first clamping member near the first abutting part and the end of the second clamping member near the second abutting part are respectively disposed on the first surface of the first plate and the second plate.

[0023] The first wall segment and the second arm segment are located on the second surface of the mounting plate at one end near the first arm segment, and the second arm segment protrudes from the connecting side of the second plate body away from the first arm segment at one end. The grip handle is located on the connecting side of the second plate body away from the first plate body.

[0024] The first abutting portion passes through the inner region of the first plate body to extend to the side of the mounting plate where the second surface is formed, and the second abutting portion passes through the outer region of the second plate body to extend to the side of the mounting plate where the second surface is formed.

[0025] Optionally, the positioning fixture further includes a locking structure for limiting and fixing the operating member relative to the grip handle when the end of the second arm segment away from the first arm segment is rotated to be close to the grip handle.

[0026] Optionally, the locking structure includes a latching member disposed on the grip handle, and the latching member has a hook at one end near the second arm segment;

[0027] When the end of the second arm segment away from the first arm segment is rotated to be close to the grip handle, the hook can engage with the second arm segment to limit and fix the operating member relative to the grip handle.

[0028] Optionally, the latching member is rotatably disposed on the grip handle, and the locking structure further includes a third elastic member disposed between the end of the latching member away from the hook and the grip handle, so as to drive the hook to engage with the second arm segment.

[0029] The present invention also proposes a production line including the positioning fixture described in any of the above embodiments.

[0030] The positioning fixture of this invention, when in use, allows the first and second reference members in the reference assembly to abut against adjacent sides of the product, respectively, to pre-position the product and the positioning fixture for proper fit. This facilitates accurate clamping of the product by the subsequent clamping components of the positioning fixture. Furthermore, the method of positioning the product by abutting against adjacent sides of the product using the first and second reference members is very fast, enabling rapid initial placement of the product and the positioning fixture, thereby improving the efficiency of product positioning.

[0031] Subsequently, the driving component simultaneously moves the first and second clamping members in the clamping assembly, causing the first clamping member to move closer to the first reference member and cooperate with it to clamp onto one of the opposite side walls of the product. Simultaneously, the second clamping member moves closer to the second reference member and cooperates with it to clamp onto the other opposite side walls of the product, thus achieving a stable clamping of the product by the positioning fixture. Since the driving component simultaneously moves the first and second clamping members, the cumbersome operation of manually driving each clamping member step by step, as required by existing technologies, is eliminated, thereby improving the efficiency of product positioning. In other words, the simultaneous movement of the first and second clamping members by the driving component, combined with the arrangement of the first and second reference members in the reference assembly abutting against adjacent sides of the product, significantly improves the efficiency of product positioning.

[0032] In addition, the simultaneous movement of the first clamping member and the second clamping member allows the product to be subjected to force on each side corresponding to the first clamping member and the second clamping member at the same time. This ensures that the force on each side of the product is uniform, thus avoiding deformation of the product due to excessive force on one side. Attached Figure Description

[0047] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0050] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0052] The inventors noted that positioning fixtures are used to pre-position and clamp products such as packaging boxes when applying labels, punching holes, or grinding, ensuring accurate subsequent operations. However, in related technologies, the individual clamping blocks of these positioning fixtures operate independently. This requires users to sequentially move each clamping block to grip the product, resulting in inefficient positioning. Furthermore, uneven force distribution on different sides of the product during sequential clamping can easily occur, leading to deformation.

[0053] Therefore, in order to solve the problems of low positioning efficiency and easy product deformation caused by the positioning fixtures in the above-mentioned related technologies, this invention proposes a positioning fixture. Please refer to the references. Figures 1 to 7 In one embodiment of the present invention, the positioning fixture 100 includes a mounting carrier 10, a reference component 30, a clamping component 50, and a driving component 70. The reference component 30 includes a first reference member 31 and a second reference member 33, which are disposed on the mounting carrier 10. The clamping component 50 includes a first clamping member 51 and a second clamping member 53. The first clamping member 51 is movably disposed on the mounting carrier 10 in directions approaching and away from the first reference member 31, and the second clamping member 53 is movably disposed on the mounting carrier 10 in directions approaching and away from the second reference member 33. The moving direction of the first clamping member 51 and the moving direction of the second clamping member 53 are set at an angle. The driving component 70 is disposed on the mounting carrier 10 and can simultaneously drive the first clamping member 51 and the second clamping member 53 to move.

[0054] The mounting carrier 10 can serve as the main structure of the positioning fixture 100, providing a mounting position for mounting the reference component 30 and the clamping component 50. This allows the various components of the positioning fixture 100 to be assembled into a single structure, facilitating subsequent handling and use of the positioning fixture 100. The mounting carrier 10 can be a plate structure, simplifying its structure and facilitating its processing and reducing manufacturing costs. Alternatively, the mounting carrier 10 can be a single-piece structure or a frame structure formed by multiple columns. This application does not limit the specific structure and shape of the mounting carrier 10, as long as it can be used to mount and support the reference component 30 and the clamping component 50. The reference component 30 can be used to abut against the product for initial positioning and clamping. Specifically, the first reference member 31 and the second reference member 33 of the reference component 30 can respectively abut against adjacent sides of the product. At this point, the first reference component 31 and the second reference component 33 form a reference angle structure, which is used to abut against one corner of the product, thus completing the initial positioning of the product and the positioning fixture 100. The first reference component 31 and the second reference component 33 can be respectively extended along the side of the mounting carrier 10 to form a long strip structure, which can better fit and abut against the side wall of the product. The first reference component 31 and the second reference component 33 can be integrally formed to improve the convenience of processing the reference component 30 and facilitate subsequent one-time installation on the mounting carrier 10. To facilitate maintenance and replacement of the reference component 30, it can be detachably connected to the mounting carrier 10. For example, the reference component 30 can be installed with screws, or it can be installed with snap-fit ​​connections or magnetic fixation. To facilitate better fit between the first reference member 31 and the second reference member 33, which are positioned at an angle, and the product, a relief hole 35 can be recessed on the inner side of the connection between the first reference member 31 and the second reference member 33 to allow for clearance of some corner structures of the product. Thus, even when the corners of the product have certain tolerances, the angle formed by the first reference member 31 and the second reference member 33 can still provide good accommodation for the corners of the product. Furthermore, this application is not limited to this; in other embodiments, the first reference member 31 and the second reference member 33 can also be spaced apart and can both extend along the side of the mounting carrier 10 away from the reference component 30 towards the reference component 30 to form a columnar structure. It should also be noted that the number of the first reference member 31 and the second reference member 33 can both be one.Of course, the reference component 30 may also include a third reference component, a fourth reference component, or more reference components. In this case, some reference components may be distributed sequentially along the side of the mounting carrier 10 where the first reference component 31 is located, and another part may be distributed sequentially along the side of the mounting carrier 10 where the second reference component 33 is located. The clamping component 50 can be used to cooperate with the reference component 30 to achieve stable clamping of the product. Specifically, the clamping component 50 can be set on the side of the mounting carrier 10 where the reference component 30 is located, and the first clamping component 51 can be arranged opposite to the first reference component 31. This relative arrangement includes the case where the first clamping component 51 and the first reference component 31 are directly opposite each other, and also includes the case where the first clamping component 51 and the first reference component 31 are staggered, ensuring that the first clamping component 51 can cooperate with the first reference component 31 to clamp the opposite side walls of the product. Similarly, the second clamping member 53 can be arranged opposite to the second reference member 33. This relative arrangement includes the case where the second clamping member 53 and the second reference member 33 are directly opposite each other, and of course, it also includes the case where the second clamping member 53 and the second reference member 33 are staggered, ensuring that the second clamping member 53 can cooperate with the second reference member 33 to clamp the opposite side walls of the product. In addition, the number of the first clamping member 51 and the second clamping member 53 can also be one. Of course, the clamping assembly 50 can also include a third clamping member, a fourth clamping member, or more clamping members. The drive assembly 70 can be used to automatically provide power or manually provide power to simultaneously drive the first clamping member 51 and the second clamping member 53 to move. The drive assembly 70 can drive the first clamping member 51 and the second clamping member 53 to slide, or it can drive the first clamping member 51 and the second clamping member 53 to rotate. In addition, in actual use, the positioning fixture 100 in this application can be used to place the positioning fixture 100 on the upper end of the product for positioning and clamping. For example, the first clamping member 51 and the second clamping member 53 can be driven away from the first reference member 31 and the second reference member 33 by the drive component 70, respectively. Then, the positioning fixture 100 can be placed on the upper end of the product, with the first reference member 31 and the second reference member 33 abutting against the adjacent sides of the product. The first clamping member 51 and the second clamping member 53 can then be moved closer to the first reference member 31 and the second reference member 33 to achieve product positioning. Alternatively, it can be used to position and clamp the product within the positioning fixture 100. For example, the first clamping member 51 and the second clamping member 53 can be driven away from the first reference member 31 and the second reference member 33 by the drive component 70, respectively. Then, the product can be placed on the positioning fixture 100, with the adjacent sides of the product abutting against the first reference member 31 and the second reference member 33. The first clamping member 51 and the second clamping member 53 can then be moved closer to the first reference member 31 and the second reference member 33 to achieve product positioning.

[0055] In use, the positioning fixture 100 of the present invention can be pre-positioned by the first reference member 31 and the second reference member 33 in the reference assembly 30 abutting against the adjacent sides of the product, thereby ensuring accurate clamping of the product by the clamping assembly 50 of the positioning fixture 100. Furthermore, the positioning method achieved by the first reference member 31 and the second reference member 33 abutting against the adjacent sides of the product is also very fast, enabling rapid initial placement of the product and the positioning fixture 100, thus improving the efficiency of product positioning. Subsequently, the driving assembly 70 can simultaneously drive the first clamping member 51 and the second clamping member 53 in the clamping assembly 50 to move, so that the first clamping member 51 moves closer to the first reference member 31 and cooperates with it to clamp one opposite side wall of the product, while the second clamping member 53 moves closer to the second reference member 33 and cooperates with it to clamp the other opposite side wall of the product, thereby achieving stable clamping of the product by the positioning fixture 100. At this time, since the first clamping member 51 and the second clamping member 53 are moved simultaneously by the driving component 70, the cumbersome operation of gradually driving each clamping member, as required by the prior art, is eliminated, thereby improving the efficiency of product positioning. That is, the setting of the driving component 70 to simultaneously drive the first clamping member 51 and the second clamping member 53, combined with the setting of the first reference member 31 and the second reference member 33 respectively abutting against adjacent sides of the product in the aforementioned reference component 30, can significantly improve the efficiency of product positioning. Furthermore, the simultaneous movement of the first clamping member 51 and the second clamping member 53 also ensures that the product is subjected to force simultaneously on each side corresponding to the first clamping member 51 and the second clamping member 53, thus ensuring uniform force on each side of the product and preventing deformation due to excessive force on one side.

[0056] Please refer to the reference. Figures 1 to 5 In one embodiment of the present invention, the driving assembly 70 includes a first elastic member 71, a second elastic member 73, and an operating member 75. The first elastic member 71 is disposed between the mounting carrier 10 and the first clamping member 51 to drive the first clamping member 51 to move in a direction close to the first reference member 31; the second elastic member 73 is disposed between the mounting carrier 10 and the second clamping member 53 to drive the second clamping member 53 to move in a direction close to the second reference member 33; the operating member 75 is movably disposed on the mounting carrier 10 and, when an external force is applied, can drive the first clamping member 51 to move in a direction away from the first reference member 31, and the second clamping member 53 to move in a direction away from the second reference member 33.

[0057] The first elastic element 71 and the second elastic element 73 are elastic components, which can be springs or plastic parts with a certain degree of elasticity. The operating element 75 can provide an operating position for the user to apply force, thereby causing the first clamping element 51 and the second clamping element 53 to move away from the first reference element 31 and the second reference element 33 respectively, thus realizing the opening of the positioning clamp 100. Figure 5 As shown, this facilitates the initial placement of the positioning clamp 100 on the upper part of the product, or the initial placement of the product on the positioning clamp 100. During this process, when the first clamping member 51 and the second clamping member 53 are moved, they respectively compress the first elastic member 71 and the second elastic member 73, causing the first elastic member 71 and the second elastic member 73 to undergo elastic deformation and generate deformation elastic force. Therefore, after the force on the operating member 75 is released, the first clamping member 51 and the second clamping member 53 can be reset under the deformation elastic force of the first elastic member 71 and the second elastic member 73, respectively, thus being driven by the first elastic member 71 and the second elastic member 73 to approach the first reference member 31 and the second reference member 33, as shown. Figure 4 As shown.

[0058] In this embodiment, the drive assembly 70 is configured with a first elastic element 71, a second elastic element 73, and an operating element 75. This makes the drive assembly 70 a purely mechanical structure, without involving circuitry or pneumatic control, thus improving the safety of the positioning fixture 100. It also significantly simplifies the structure of the drive assembly 70, thereby greatly reducing the manufacturing cost of the positioning fixture 100. More importantly, the drive assembly 70 uses the first elastic element 71 and the second elastic element 73 to drive the first clamping element 51 and the second clamping element 53 to approach the first reference element 31 and the second reference element 33 respectively. This allows for buffering when the first clamping element 51 and the second clamping element 53 contact the product, preventing collisions and impacts that could damage the product during movement, thus further ensuring product quality. Of course, it should be noted that this application is not limited to this. In other embodiments, two motors and two transmission components are provided on the mounting carrier 10. One transmission component is connected to one of the two motors and the first clamping member 51, and the other transmission component is connected to the other of the two motors and the second clamping member 53. In this case, the two motors drive the first clamping member 51 and the second clamping member 53 to move through the two transmission components, realizing the automatic driving of the positioning fixture on the two first clamping members 51 and the second clamping member 53, thereby improving the automation level of the positioning fixture. The transmission component may include a lead screw and a slide sleeved on the lead screw. In this case, when one motor drives the lead screw to rotate, it can drive the slide sleeved on the lead screw to move, thereby driving the first clamping member 51 connected to the slide to move closer to or away from the first reference member 31; while when another motor drives the other lead screw to rotate, it can drive the slide sleeved on the lead screw to move, thereby driving the second clamping member 53 connected to the slide to move closer to or away from the second reference member 33. Of course, the transmission assembly can also be a pulley structure consisting of a driving pulley, a driven pulley, and a belt. In this case, the first clamping member 51 can be connected to the belt in one transmission assembly, and the second clamping member can be connected to the belt in another transmission assembly. Alternatively, in one embodiment, the drive assembly can also include two cylinders, both of which are mounted on the mounting carrier 10. In this case, the first clamping member 51 is connected to one of the two cylinders, and the second clamping member 53 can be connected to the other of the two cylinders.

[0059] Furthermore, please refer to the references. Figure 1 , Figure 3 , Figure 6 as well as Figure 7The operating member 75 includes a first arm segment 751 and a second arm segment 752 connected to each other and arranged at an angle. The connection between the first arm segment 751 and the second arm segment 752 is rotatably connected to the mounting carrier 10. The first clamping member 51 is provided with a first abutting part 511, which abuts against the inner side of the first arm segment 751. The second clamping member 53 is provided with a second abutting part 531, which abuts against the outer side of the second arm segment 752. When the end of the second arm segment 752 away from the first arm segment 751 is rotated by an external force, the first arm segment 751 can abut against and drive the first abutting part 511 away from the first reference member 31, and the second arm segment 752 can abut against and drive the second abutting part 531 away from the second reference member 33.

[0060] The first arm segment 751 and the second arm segment 752 are set at an angle, meaning that the first arm segment 751 and the second arm segment are connected by a bend. When the first arm segment 751 and the second arm segment 752 are linear, the angle formed by the respective extending directions of the first arm segment 751 and the second arm segment 752 is the angle enclosed by the first arm segment 751 and the second arm segment 752. When the first arm segment 751 and the second arm segment 752 have an arc-shaped structure, the angle formed by the respective tangents of the first arm segment 751 and the second arm segment 752 is the angle enclosed by the first arm segment 751 and the second arm segment 752. Therefore, the first arm segment 751 and the second arm segment 752 can be said to roughly form an L-shaped structure, and the end of the second arm segment 752 furthest from the first arm segment 751 can be used to raise the operating position for the user to apply force. The first abutting portion 511 on the first clamping member 51 and the second abutting portion 531 on the second clamping member 53 can engage with the operating member 75 for transmission. Therefore, when the second arm segment 752 is rotated by the user, the first abutting portion 511 and the second abutting portion 531 can be engaged to drive the first clamping member 51 and the second clamping member 53. Specifically, the first abutting portion 511 abuts against the inner side of the first arm segment 751, meaning it abuts against the side of the first arm segment 751 located in the area where it forms an angle with the second arm segment 752. The second abutting portion 531 abuts against the outer side of the second arm segment 752, meaning it abuts against the side of the second arm segment 752 located away from the area where it forms an angle with the first arm segment 751. The first abutment portion 511 and the second abutment portion 531 can have a cylindrical shape, a square column shape, a plate shape, or other shapes, etc., and this application does not limit them. Preferably, the first abutment portion 511 and the second abutment portion 531 can both be cylindrical structures, so that the shape of the first abutment portion 511 is more regular and can better abut with the first arm segment 751 and the second arm segment 752 respectively through the consistency of its circumference.

[0061] In this embodiment, the operating member 75 is configured as a first arm segment 751 and a second arm segment 752, and is rotatably mounted on the mounting carrier 10. This allows for simple operation by rotating the second arm segment 752 of the operating member 75 to drive the first clamping member 51 and the second clamping member 53, thereby improving the ease of use of the positioning fixture 100. Furthermore, when the operating member 75 is driven to rotate by an external force, it can directly abut against the first abutment portion 511 and the second abutment portion 531 to drive the first clamping member 51 and the second clamping member 53. This ensures that the driving force of the operating member 75 is transmitted to the first clamping member 51 and the second clamping member 53 in a timely, efficient, and stable manner, thus guaranteeing the driving efficiency and stability of the operating member 75. Moreover, this eliminates the need for a complex transmission structure, further simplifying the structure of the drive assembly 70 and improving the ease of manufacturing the positioning fixture 100 while reducing manufacturing costs. Of course, it should be noted that this application is not limited to this. In other embodiments, the operating member 75 may also be a knob or a slider, and is connected to the first clamping block 513 and the second clamping block 537 respectively by two connecting ropes. When the operating member 75 rotates or slides, the first clamping block 513 and the second clamping block 537 can be moved by the two connecting ropes respectively.

[0062] Furthermore, please refer to the references. Figures 3 to 7 The mounting carrier 10 is provided with a grip handle 11. The grip handle 11 and the end of the second arm segment 752 away from the first arm segment 751 are arranged opposite to each other. When the end of the second arm segment 752 away from the first arm segment 751 is rotated toward the grip handle 11 by an external force, the first arm segment 751 and the second arm segment 752 can respectively abut and drive the first abutting part 511 and the second abutting part 531.

[0063] The grip handle can also be used to provide a grip position for the user to hold. That is, when the positioning clamp 100 of this application is in use, the user can hold the grip handle 11 with one hand and at the same time use the same hand to hold the end of the drive second arm segment 752 away from the first arm segment 751.

[0064] In this embodiment, the grip handle 11 allows the user to hold the grip handle 11 and the second arm segment 752 of the operating member 75 away from the first arm segment 751 with one hand, and further tighten the grip to drive the operating member 75 to rotate. That is, this arrangement eliminates the need for the user to use one hand to restrain the mounting carrier 10 and then use the other hand to drive the operating member 75 to rotate, thereby affecting the first clamping member 51 and the second clamping member 53. This allows for single-handed use of the positioning angle, further improving the ease of use of the positioning clamp 100.

[0065] Furthermore, please refer to the references. Figures 1 to 3 The mounting carrier 10 is defined to have a first surface 12 and a second surface 13 arranged back to back, and a connecting side 14 connecting the first surface 12 and the second surface 13; a first reference member 31, a second reference member 33, a first clamping member 51 and a second clamping member 53 are provided on the first surface 12; the ends of the first arm segment 751 and the second arm segment 752 near the first arm segment 751 are provided on the second surface 13; the end of the second arm segment 752 away from the first arm segment 751 protrudes from the connecting side 14; a grip handle 11 is provided on the connecting side 14; a first abutment portion 511 and abutment portion 531 extend to the side of the mounting carrier 10 where the second surface 13 is formed, so as to abut against the inner side of the first arm segment 751 and the outer side of the second arm segment 752 near the first arm segment 751, respectively.

[0066] When the mounting carrier 10 is placed horizontally, the first surface 12 and the second surface 13 can be the upper and lower surfaces of the mounting carrier 10, and the connecting side peripheral surface can be the side surface of the mounting carrier 10. The end of the second arm segment 752 away from the first arm segment 751 protruding from the connecting side surface 14 means that, on the horizontal projection plane, the end of the second arm segment 752 away from the first arm segment 751 is located outside the projection of the mounting carrier 10, so that the end of the second arm segment 752 away from the first arm segment 751 can be exposed for the user to hold and operate.

[0067] In this embodiment, the reference component 30 and the clamping component 50 are disposed on the first surface 12 of the mounting carrier 10, the operating component 75 is disposed on the second surface 13 of the mounting carrier 10, and the grip handle 11 is disposed on the connecting side 14 of the mounting carrier 10. This allows the reference component 30, the clamping component 50, the operating component 75, and the grip handle 11 to be more compactly distributed on the mounting carrier 10, thereby reducing the overall size of the positioning fixture 100 and facilitating the setup of each mechanism. It should be noted that this application is not limited to this; in other embodiments, the operating component 75 and the grip handle 11 may also be disposed on the side of the mounting carrier 10 where the reference component 30 and the clamping component 50 are located. In this case, the mounting carrier 10 needs to have a support frame protruding from the surface where the reference component 30 and the clamping component 50 are located to mount the operating component 75 and the grip handle.

[0068] Furthermore, please refer to the references. Figure 1 , Figure 3 , Figure 6 as well as Figure 7The second arm segment 752 includes a connecting segment 753 and a gripping segment 754. One end of the connecting segment 753 is connected to the first arm segment 751 and is set at an angle to the first arm segment 751. The other end of the connecting segment 753 protrudes from the connecting side 14. The gripping segment 754 is connected to the end of the connecting segment 753 away from the first arm segment 751, and the gripping segment 754 is located on the side of the connecting segment 753 facing the second surface 13, so that the gripping segment 754 and the grip handle 11 are on the same plane.

[0069] When the mounting carrier 10 is placed horizontally, the grip section 754 and the grip handle 11 being on the same plane means that the grip section 754 and the grip handle 11 are at the same height. This includes cases where the upper and lower surfaces of the grip section 754 and the grip handle 11 are coplanar, and cases where the upper and lower surfaces of the grip section 754 and the grip handle 11 have a slight height difference.

[0070] In this embodiment, the gripping section 754 of the second arm segment 752 of the operating member 75 is positioned at the same height as the grip handle 11, allowing the user to grip the gripping section 754 and the grip handle 11 more comfortably, thereby further improving the ease of use of the positioning clamp 100. The connecting section 753, away from the second arm segment 752, can be inclined, tilting towards the side facing the first arm segment 751. This allows for a larger distance between the gripping section 754 and the second abutment portion 531 in the rotational circumferential direction of the gripping portion. This facilitates the movement of the second clamping member 53 to the required stroke by the end of the connecting section 753 near the first arm segment 751 after the gripping section 754 has rotated a certain angle. Furthermore, for ease of maintenance and replacement, the gripping section 754 and the connecting section 753 can be detachably connected. For example, they can be connected by screws or clips. A rotating hole 755 can be provided at the connection between the connecting section 753 and the first arm section 751. The mounting carrier 10 can be provided with a rotating shaft 15, which is inserted into the rotating hole 755 to achieve a rotatable connection between the operating member 75 and the mounting carrier 10. To reduce wear, a rolling bearing 758 can be provided in the rotating hole 755. Specifically, the operating member 75 can have a mounting groove 756 provided at one end of the rotating hole 755 to accommodate the rolling bearing 758. Then, by covering it with a cover plate 757 and inserting a screw through the cover plate into the rotating shaft 15 that extends into the rolling bearing 758, a detachable connection between the operating member 75 and the mounting carrier 10 can be achieved, thereby improving the convenience of maintenance and replacement.

[0071] Please refer to the reference. Figures 1 to 3 ,as well as Figure 6 and Figure 7In one embodiment of the present invention, the mounting carrier 10 includes a main body plate 16 and a mounting plate 17. The mounting plate 17 includes a first plate 171 and a second plate 173 connected to each other and arranged at an angle. The side of the first plate 171 away from the second plate 173 is connected to one side of the main body plate 16. A first reference member 31 and a second reference member 33 are disposed on the first surface 12 of the main body plate 16. One end of the first clamping member 51 near the first abutment portion 511 and one end of the second clamping member 53 near the second abutment portion 531 are respectively disposed on the first surface 12 of the first plate 171 and the second plate 173. A first wall segment and a second arm segment 7 One end of the second arm segment 751 is located on the second surface 13 of the mounting plate 17, and the end of the second arm segment 752 away from the first arm segment 751 protrudes from the connecting side 14 of the second plate 173 away from the first plate 171. The grip handle 11 is located on the connecting side 14 of the second plate 173 away from the first plate 171. The first abutting part 511 passes through the inner region of the first plate 171 to extend to the side of the mounting plate 17 where the second surface 13 is formed. The second abutting part 531 passes through the outer region of the second plate 173 to extend to the side of the mounting plate 17 where the second surface 13 is formed.

[0072] Mounting plate 17 and main plate 16 can be located on the same horizontal plane, while the first plate 171 and the second plate 173 can roughly form an L-shaped structure. In this case, the end of the first clamping member 51 away from the first abutment portion 511 can be located on the mounting plate 17 or the main plate 16, ensuring that it can subsequently cooperate with the first reference member 31 to clamp the product. The end of the second clamping member 53 away from the second abutment portion 531 needs to be located on the main plate 16 so that it can cooperate with the second reference member 33 located on the main plate 16 to clamp the product. The first abutment portion 511 passing through the inner region of the first plate 171 means that the end of the first abutment portion 511 away from the first clamping frame passes through the angle region formed by the first plate 171 and the second plate 173. The second abutment portion 531 passing through the outer region of the second plate 173 means that the second abutment portion 531 passes through the region outside the angle formed by the first plate 171 and the second plate 173 and is positioned close to the second plate 173.

[0073] In this embodiment, the mounting carrier 10 is configured as a main body plate 16 and a mounting plate 17 formed by combining a first plate 171 and a second plate 173 arranged at an angle. This allows the mounting carrier 10 to better avoid the first abutment portion 511 and the second abutment portion 531, allowing the first abutment portion 511 and the second abutment portion 531 to extend to one side of the second surface 13 of the mounting carrier 10. More importantly, the structures of the main body plate 16 and the mounting plate 17, which are separately divided into the mounting carrier 10, are very simple, making them easy to manufacture. After each is formed, they can be assembled to form the mounting carrier 10 as a whole, thus improving the convenience of processing and shaping the mounting carrier 10. To facilitate maintenance and replacement of the mounting plate 17, the mounting plate 17 and the main body plate 16 can be detachably connected, for example, by screws or clips. To ensure the strength and ease of manufacturing of the grip handle 11, the grip handle 11 and the second plate 173 can be integrally formed. It should also be noted that in other embodiments, the mounting carrier 10 can also be a plate structure, in which case sliding holes can be provided to avoid the movement of the first abutment part 511 and the second abutment part 531 respectively.

[0074] Furthermore, please refer to the references. Figure 1 , Figure 6 as well as Figure 10 The first plate 171 has a first mounting base 172 on its first surface 12, and the second plate 173 has a second mounting base 174 on its first surface 12. The first clamping member 51 includes a first sliding rod 512 and a first clamping block 513. The first sliding rod 512 is slidably disposed in the first mounting base 172 in the direction of approaching and moving away from the first reference member 31. The first clamping block 513 is disposed at the end of the first sliding rod 512 near the first reference member 31, and the first abutting part 511 is disposed at the end of the first sliding rod 512 away from the first clamping block 513. The second clamping member 53 includes a second sliding rod 532. The second sliding rod 532 is slidably mounted on the second mounting base 174 in the direction of approaching and away from the second reference member 33. One end of the extension arm 533 is connected to the end of the second sliding rod 532 near the second reference member 33, and the other end extends along the sliding direction of the first sliding rod 512 near the first reference member 31. The second clamping block 537 is connected to the end of the extension arm 533 away from the second sliding rod 532 and is set at an angle with the first clamping block 513. The second abutment part 531 is provided at the end of the second sliding rod 532 away from the extension arm 533.

[0075] In this embodiment, the first mounting base 172 and the second mounting base 174 can respectively provide mounting positions for the first clamping member 51 and the second clamping member 53, so as to better install the first clamping member 51 and the second clamping member 53. At the same time, it can ensure that the structure of the first plate 171 and the second plate 173 themselves will not be affected by the connection structure of the first clamping member 51 and the second clamping member 53, so as to ensure that the first plate 171 and the second plate 173 have a certain strength to support the installation of the first clamping member 51 and the second clamping member 53. The first clamping member 51 includes a first sliding rod 512 and a first clamping block 513, so that the first sliding rod 512 can be directly inserted into the first mounting base 172 to achieve the sliding connection of the first sliding rod 512, thereby simplifying the sliding installation of the first clamping member 51. The first clamping block 513 can fit more appropriately against the product to improve the stability of subsequent product clamping. Similarly, the second clamping member 53 includes a second slide rod 532, an extension arm 533, and a second clamping block 537. This allows the second slide rod 532 to be directly inserted into the second mounting base 174 for sliding connection, simplifying the sliding installation of the second clamping member 53. The extension arm 533 extends the second clamping block 537 to ensure it is positioned on the side of the first clamping block 513 away from the first slide rod 512, thus cooperating with the second reference member 33 to clamp and fix the product. The second clamping block 537 also fits snugly against the product, improving the stability of subsequent product clamping. To further improve the compactness of the first clamping member 51 and the second clamping member 53, in the sliding direction of the first slide bar 512 near the first reference member 31, the extension arm 533 may include a first segment 534, a second segment 536, and a third segment 536 connected in sequence. The second segment 536 is set at an angle to both the first segment 534 and the third segment 536. The first segment 534 is located at the end of the second segment 536 closer to the second reference member 33 than the third segment 536. That is, the first plate 171 and the second plate 173 of the extension arm 533 can be located within the space enclosed by the first mounting base 172 and the second mounting base 174, allowing them to be distributed more compactly and further reducing the overall volume of the positioning fixture 100. Similarly, in order to make the extension arm 533 and the second slide bar 532 more compact and stable, the end of the extension arm 533 away from the second slide bar 532, that is, the end of the third segment 536 away from the second segment 536, can be embedded in the second clamping block 537. Furthermore, it should be noted that this application is not limited to this; in other embodiments, the first clamping member 51 may only include the first clamping block 513, in which case the first clamping block 513 can be slidably connected to the sliding groove provided on the first plate 171 by setting a slider.Similarly, the second clamping member 53 may also consist only of the second clamping block 537 and the extension arm 533. In this case, the extension arm 533 can be slidably connected to the slide groove provided on the second plate 173 by setting a slider.

[0076] Furthermore, to simplify the limiting structure of the first slide bar 512 on the first mounting base 172, please refer to the reference. Figures 6 to 10The first clamping member 51 may further include a first limiting block 514, which is located at the end of the first slide rod 512 away from the first clamping block 513, and a first abutting portion 511 is located at the first limiting block 514. In this case, after the first slide rod 512 passes directly through the first mounting base 172, it can be limited by the first limiting block 514 to prevent the first slide rod 512 from sliding off the first mounting base 172. Similarly, in order to simplify the limiting structure of the second slide rod 532 on the second mounting base 174, the second clamping member 53 may further include a second limiting block 538, which is located at the end of the second slide rod 532 away from the extension arm 533, and a second abutting portion 531 is located at the second limiting block 538. To improve the sliding stability of the first slide rod 512, the first clamping member 51 may further include a first linear bearing 515, which passes through the first mounting base 172, and the first slide rod 512 is slidably passed through the first linear bearing 515. In this case, the first linear bearing 515 can serve as a guide and reduce wear. Similarly, to improve the sliding stability of the second slide rod 532, the second clamping member 53 may further include a second linear bearing 539, which passes through the second mounting base 174, and the second slide rod 532 is slidably passed through the second linear bearing 539. To facilitate the installation of the first elastic element 71 and the second elastic element 73, the first elastic element 71 may be sleeved on the first slide rod 512 and located between the first clamping block 513 and the first mounting base 172. The second elastic element 73 may be sleeved on the second slide rod 532 and located between the extension arm 533 and the second mounting base 174. Of course, when the first clamping member 51 includes a first linear bearing 515, the end of the first elastic member 71 away from the first clamping block 513 can abut against the first linear bearing 515. When the second clamping member 53 includes a second linear bearing 539, the end of the second elastic member 73 away from the first clamping block 513 can abut against the second linear bearing 539. In addition, to improve the maintenance and replacement of the first clamping member 51 and the second clamping member 53, the first slide rod 512 and the first clamping block 513 can be detachably connected, and the first limiting block 514 and the first slide rod 512 can also be detachably connected, and the first abutting part 511 can also be detachably connected to the first limiting block 514. Similarly, the second slide rod 532 and the extension arm 533, the extension arm 533 and the second clamping block 537, the second limiting block 538 and the second slide rod 532, and the second abutting part 531 and the second limiting block 538 can all be detachably connected. The first mounting base 172 and the second mounting base 174 can also be detachably connected to the first plate 171 and the second plate 173, respectively. The detachable connections can be made using screws or snap-fit ​​connections, etc.

[0077] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of the present invention, the positioning clamp 100 further includes a locking structure 90, which is used to limit and fix the operating member 75 relative to the grip handle 11 when the end of the second arm segment 752 away from the first arm segment 751 is rotated to be close to the grip handle 11.

[0078] When the end of the second arm segment 752 away from the first arm segment 751 rotates to near the grip handle 11, that is, when the operating member 75 drives the first abutment part 511 and the second abutment part 531, the first clamping block 513 of the first clamping member 51 moves away from the first reference member 31 to a preset position, and the second clamping block 537 of the second clamping member 53 moves away from the second reference member 33 to a preset position. In short, after the first clamping member 51 and the second clamping member 53 are in the driven open state, a locking force can be provided by the locking structure 90 to limit and fix the operating member 75. Once the force acting on the operating member 75 is removed, the first clamping member 51 and the second clamping member 53 are reset under the action of the first elastic member 71 and the second elastic member 73.

[0079] In this embodiment, the locking structure 90 locks the operating member 75, so that it can remain in the state where the first clamping member 51 and the second clamping member 53 are open, so that it is not necessary to continuously grip the operating member 75 and the grip handle 11, thereby further improving the convenience of using the positioning fixture 100.

[0080] Furthermore, please refer to the references. Figure 4 and Figure 5 The locking structure 90 may include a latching member 91, which is provided on the grip handle 11. The latching member 91 has a hook 911 at one end near the second arm segment 752. When the end of the second arm segment 752 away from the first arm segment 751 is rotated to be close to the grip handle 11, the hook 911 can be latched onto the second arm segment 752 so that the operating member 75 is limited and fixed relative to the grip handle 11.

[0081] In this embodiment, the snap-fit ​​member 91 allows the operating member 75 to be squeezed at the end of the snap-fit ​​member 91 with the snap hook 911 during the gripping and rotation process, and rotated to engage and fix with the snap hook 911 on the snap-fit ​​member 91. At this time, the locking structure 90 locks the operating member 75 simultaneously during the gripping and rotation process of the operating member 75. This eliminates the need for additional operations to limit and fix the operating member 75 after the gripping and rotation is completed, thereby further improving the ease of use of the positioning fixture 100. The snap hook 911 of the snap-fit ​​member 91 can engage with the gripping section 754 of the second arm segment 752 of the operating member 75. In addition, it should be noted that, in other embodiments, the locking structure 90 can also be a pin. That is, after the operating member 75 is rotated to the position, the part of the operating member 75 can be located below the grip handle 11, so that the pin passing through the grip handle 11 and the operating member 75 located below the grip handle 11 can be used for limiting.

[0082] Furthermore, please refer to the references. Figure 4 and Figure 5 The latching member 91 is rotatably disposed on the grip handle 11. The locking structure 90 also includes a third elastic member 93, which is disposed between the end of the latching member 91 away from the hook 911 and the grip handle 11, so as to drive the hook 911 to engage with the second arm segment 752.

[0083] In this embodiment, the latching member 91 is rotatably configured, and a third elastic element 93 is provided at the end of the latching member 91 away from the latch hook 911. This third elastic element 93 provides sufficient elastic force to drive the latching member 91 to stably engage with the gripping section 754 of the second arm segment 752. Simultaneously, when it is necessary to unlock the operating member 75, simply pressing the end of the latching member 91 away from the latch hook 911 will disengage the latch hook 911 from the operating member 75, thus freeing the operating member 75 from locking. Unlocking the operating member 75 is also very simple, thereby further improving the ease of use of the positioning clamp 100. After the operating member 75 is unlocked by pressing the latch 91, the first clamping member 51 and the second clamping member 53 can slide and reset under the action of the first elastic member 71 and the second elastic member 73, respectively. The operating member 75 can also be driven to reset by abutting under the first abutting part 511 of the first clamping member 51 and the second abutting part 531 of the second clamping member 53. The latching member 91 can be reset under the action of the third elastic member 93.

[0084] Please refer to the reference. Figures 1 to 3 In one embodiment of the present invention, the mounting carrier 10 is provided with a through hole 18, which penetrates the surface of the mounting carrier 10 facing and away from the reference component 30 and the clamping component 50, and is located inside the area enclosed by the reference component 30 and the clamping component 50.

[0085] In this embodiment, the mounting carrier 10 is provided with a through hole 18, so that when the positioning jig 100 is clamped on the upper end of the product, the upper surface of the product can be exposed through the through hole 18, which facilitates the necessary processing operations on the product. For example, when it is necessary to attach a label to the upper surface of the product, after the positioning jig 100 is clamped on the upper end of the product, the adjacent two hole walls of the through hole 18 can also form a reference line, thereby facilitating accurate labeling of the product at a preset position. Wherein, when the mounting carrier 10 includes a main body plate 16 and a mounting plate 17, the main body plate 16 is provided with a through hole 18, which penetrates the first surface 12 and the second surface 13 of the main body plate 16. Further, in order to facilitate the quick placement of the positioning jig 100 on the upper end of the product, the end of the first reference member 31 away from the mounting carrier 10 is provided with a first guide surface 311. In the direction from the end of the first reference member 31 near the mounting carrier 10 to the end away from the mounting carrier 10, the distance between the first guide surface 311 and the first clamping member 51 is increased. The second reference member 33 has a second guide surface 331 at its end away from the mounting carrier 10. The distance between the second guide surface 331 and the second clamping member 53 increases in the direction from the end of the second reference member 33 near the mounting carrier 10 to the end away from the mounting carrier 10. In this case, the arrangement of the first guide surface 311 and the second guide surface 331 can reduce the alignment accuracy requirements of the positioning fixture 100 and the product, thereby facilitating rapid preliminary alignment and placement. The first guide surface 311 and the second guide surface 331 can be inclined surfaces to improve the convenience of their processing and forming. Of course, in other embodiments, the first guide surface 311 and the second guide surface 331 can also be arc-shaped surfaces.

[0086] The present invention also proposes a production line including a positioning fixture 100. The specific structure of the positioning fixture 100 is as described in the above embodiments. Since this production line adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The production line may also include a conveyor line, through which products such as packaging boxes or shells can be transported, and the positioning fixture 100 can be used to position and clamp the packaging boxes or shells transported by the conveyor line.

[0087] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
