[0045] The beneficial effects of this utility model are as follows:
[0046] One aspect of this utility model provides a clamping structure for a conductive component, comprising a first clamping block and a second clamping block disposed opposite to each other. At least one of the first clamping block and the second clamping block is drivable. The end face of the first clamping block near the second clamping block includes a first clamping surface for contacting the product; and a regularized surface extending obliquely from the upper edge of the first clamping surface toward the second clamping block. The end face of the second clamping block near the first clamping block includes a second clamping surface that cooperates with the first clamping surface for contacting the product; and a clearance slope extending obliquely from the upper edge of the second clamping surface away from the first clamping block to avoid the regularized surface. During the clamping process of the first and second clamping surfaces on the product from both sides, the regularized surface can restrict the product in the vertical direction during clamping. As the first and second clamping blocks move closer together, the regularized surface can cooperate with the first clamping surface to limit the product, thereby achieving the product being clamped by the first and second clamping surfaces in a corrected position. Especially for electrical connectors that are small in size, thin and flat in structure, have a large amount of structural deformation, and may undergo slight deformation during the transfer process, the clamping structure provided by this utility model can effectively prevent the product from tilting up in the vertical direction, affecting the accuracy of clamping, causing uneven clamping force on the product, and preventing local deformation of the product.
[0047] Another aspect of this utility model provides a fixture including the above-mentioned clamping structure. The fixture includes multiple clamping structures arranged in different directions. A single clamping structure clamps the product from both sides, which can fix the product in a regular position during the clamping process. The multiple clamping structures in different directions exert forces on the product in the X and Y directions respectively, correcting the deformation of the product in the plane and restoring it to its initial structural state.

[0062] To more clearly illustrate this utility model, the preferred embodiments and accompanying drawings will be used for further description. Similar components in the drawings are indicated by the same reference numerals. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of this utility model.
[0063] Electrical connectors are frequently used in electronic products to connect components at different locations. Examples include conductive sheets with multiple bends and flexible circuit boards for connection. These connectors have multiple contact ends facing different directions depending on the connection orientation. They are characterized by their small size, thin and flat structure, and large self-deformation capacity. Slight deformation can occur during handling, affecting the positioning and fixation of the fixture during testing, thus preventing accurate contact continuity testing by the testing equipment. It should be noted that the products described in this embodiment refer to, but are not limited to, various flexible conductive components with these characteristics, including but not limited to those with small size, thin and flat structure, and large self-deformation capacity.
[0064] Example 1
[0065] In one embodiment, according to one aspect of the present invention, the present invention first provides a clamping structure for conductive components. This clamping structure can well adapt to the clamping and positioning of products with large deformation, and realize the clamping and positioning of such products in a more convenient manner. During the clamping process, it automatically corrects slight deformation of such products, so that they can be accurately clamped and fixed, providing a basis for improving the accuracy of subsequent testing.
[0066] Specifically, first refer to Figure 1 , Figure 2 , Figure 3As shown, a clamping structure for a conductive component includes a first clamping block 10 and a second clamping block 11 disposed opposite each other. At least one of the first clamping block 10 and the second clamping block 11 can be driven to move away from each other. The end face of the first clamping block 10 near the second clamping block 11 includes a first clamping surface 101 for contacting the product, and a regular surface 102 extending obliquely from the upper edge of the first clamping surface 101 toward the second clamping block 11. To clearly illustrate the structure shown in the figure, the product is labeled as a conductive component 90 to show the relationship between the clamping structure and the product. In this embodiment, the end face of the second clamping block 11 near the first clamping block 10 includes: a second clamping surface 111 that cooperates with the first clamping surface 101 to abut against the product, and a clearance slope 112 that extends obliquely from the upper edge of the second clamping surface 111 away from the first clamping block 10 to avoid the regular surface 102. The conductive component 90 is placed between the first clamping surface 101 and the second clamping surface 111. The driving structure drives the first clamping block 10 and the second clamping block 11 to move away from or closer to each other, thereby achieving the clamping and positioning of the product or the release of the product by the clamping structure.
[0067] This embodiment provides a clamping structure. In an initial state, the first clamping block 10 and the second clamping block 11 are located close to each other in a first working state. In this first working state, the first clamping surface 101 and the second clamping surface 111 are in a cooperating state to clamp and fix the product. When at least one of the first clamping block 10 and the second clamping block 11 is driven, the first clamping block 10 and the second clamping block 11 move away from each other to form a second working state. In this second working state, the first clamping surface 101 and the second clamping surface 111 cooperate to release the product for replacement and re-clamping.
[0068] Furthermore, when the first clamping block 10 and the second clamping block 11 are in a first working position close to each other, in this first working position, when a product is present, the first clamping surface 101 and the second clamping surface 111 cooperate to clamp and fix the product. When no product is clamped, the first clamping surface 101 and the second clamping surface 111 are close together in a contacting or non-contacting state. Optionally, the positions of the first clamping block 10 and the second clamping block 11 in the first working position are adjustable to ensure that the two clamping blocks can clamp the product in a better manner based on the product width. This utility model does not limit this aspect.
[0069] This implementation method Figures 1 to 3In the structure shown, there are two sets of first clamping blocks 10 and second clamping blocks 11 arranged opposite to each other. The first clamping blocks 10 and second clamping blocks 11 in the two sets move synchronously, and the two first clamping blocks 10 in the two sets are connected and fixed to form an integral structure. Similarly, the two second clamping blocks in the two sets are connected and fixed to form an integral structure.
[0070] At least one of the first clamping block 10 and the second clamping block 11 can be driven. In one case, the first clamping block 10 is set to be driven by the driven structure, and the second clamping block 11 is set in a fixed position. The first clamping block 10 moves closer to the second clamping block 11 under the drive of the drive structure, thereby realizing the cooperation of the first clamping surface 101 and the second clamping surface 111 to clamp and fix the product. When the first clamping block 10 moves away from the second clamping block 11 under the drive of the drive structure, the first clamping surface 101 is disengaged from the product, and the product is released from the clamped and fixed state for replacement and placement of other products for testing.
[0071] Similarly, in another case, the second clamping block 11 is set to be driven by the driving structure, the first clamping block 10 is set in a fixed position, and the second clamping block 11 moves closer to the first clamping block 10 under the drive of the driving structure, thereby realizing the cooperation of the first clamping surface 101 and the second clamping surface 111 to clamp and fix the product. When the second clamping block 11 moves away from the first clamping block 10 under the drive of the driving structure, the second clamping surface 111 is detached from the product, and the product is released from the clamped and fixed state for replacement and placement of other products for testing.
[0072] In another scenario, the first clamping block 10 and the second clamping block 11 are driven by the driving structure to move synchronously or asynchronously in the clamping direction. This allows the two clamping blocks to fix and clamp the product from both sides without changing its initial placement position, thereby correcting and adjusting the product position and preventing product damage caused by the clamping structure's inability to accurately clamp the product due to the initial placement position being skewed.
[0073] Existing clamping structures in this field typically focus on how to accurately position a product in its initial state using positioning structures, or how to accurately and stably clamp and fix the product. For accurate product positioning, existing clamping structures often employ various positioning structures on the product placement plate. This allows the product to be precisely positioned and bounded by these structures when placed in the fixture, thus solving the subsequent clamping accuracy problem. Regarding accurate and stable product clamping and fixing, one approach, as mentioned above, is to position the product initially using positioning structures to increase clamping accuracy and stability. Another approach is to increase the contact area between the clamping end and the product to overcome the problem of product misalignment and ineffective clamping. However, these clamping structures are usually designed for products with a certain structural strength, such as display panels, chip structures, and fixture carriers. Clamping and positioning structures capable of accommodating products with larger deformation are not commonly seen.
[0074] The clamping structure for conductive components provided in this embodiment can effectively prevent problems such as the product tilting in the vertical direction, affecting the accuracy of clamping, uneven clamping force on the product, and local deformation of the product. Specifically, the end face of the first clamping block 10 near the second clamping block 11 includes a regular surface 102 extending obliquely from the upper part of the first clamping surface 101 toward the second clamping block 11. This regular surface 102 can restrict the product in the vertical direction during clamping. As the first clamping block 10 and the second clamping block 11 move closer together, the regular surface 102 can cooperate with the first clamping surface 101 to form a groove-shaped structure, limiting the product in the vertical direction at the initial stage of contact with the product, so that the product can be clamped in the correct position by the first clamping surface 101 and the second clamping surface 111. Especially for electrical connector products that are small in size, thin and flat in structure, have a large amount of structural deformation, and may undergo slight deformation during the transfer process, the regular surface, the first clamping surface 101 and the second clamping surface 111 can well adapt to the clamping and positioning of such products with large deformation during clamping. During the clamping process, it automatically corrects the slight deformation of products with large deformation in the X, Y and Z directions, so that they can be accurately clamped and fixed.
[0075] It should be noted that at least one of the first clamping block and the second clamping block described in this embodiment can be driven, and the driving form includes, but is not limited to, active driving and semi-active driving. Among them, active driving refers to actively driving the first clamping block and / or the second clamping block to reciprocate within the stroke by means of a drive cylinder, drive motor, linkage, or manual operation, that is, the driving force acts directly on the clamping block, and the transition of the clamping block between the first station state and the second station state is carried out through the direct action of the driving force.
[0076] Passive drive refers to the application of force in a single direction to the first and / or second clamping blocks only during the transition between the first and second working states, using a drive cylinder, drive motor, linkage, or manual operation. When the unidirectional force is lost, the first and / or second clamping blocks must be reset by a reset element such as a spring, torsion spring, or damper. It should be noted that any other variations or modifications made based on the above description are obvious variations or modifications derived from the technical solution of this utility model and are within the protection scope of this utility model.
[0077] Reference Figures 1 to 3 As shown, in one embodiment, the clamping structure includes two sets of opposing first clamping blocks 10 and second clamping blocks 11. The two sets of opposing first clamping blocks 10 and second clamping blocks 11 are arranged orthogonally along the clamping direction, and there are gaps 12 between the two sets of first clamping blocks 10 and between the two sets of second clamping blocks 11. Through the gaps 12, multiple clamping blocks can act on the product at multiple clamping points with different action distances, realizing segmented clamping. On the one hand, this can improve the stability of the clamping blocks clamping the product, and on the other hand, it can avoid the product being subjected to localized stress and deformation at the stress point due to the action of the clamping blocks. In addition, when multiple clamping structures correct the product from different directions, the multiple clamping blocks of each clamping structure can effectively disperse the stress on the product when correcting and correcting the deformed product, especially when correcting and correcting deformation of the same product in different directions or related directions in the same plane.
[0078] Example 2
[0079] In one embodiment, according to another aspect of the present invention, a fixture is also provided, the fixture including a substrate for placing a product and a clamping structure as described above disposed on the substrate. In this embodiment, the fixture further includes a push block, which is slidably disposed on the substrate as a driving member. The push block is located between a first clamping block and a second clamping block, and the sliding direction of the push block is orthogonal in a plane to the product clamping direction of the clamping structure. At least one sidewall edge of the push block includes a groove, and at least one of the first and second clamping blocks includes a contact portion located within the groove. The groove includes an inclined pushing surface; as the push block slides, the contact portion abuts against the inclined pushing surface and moves along the inclined pushing surface, and the clamping block including the contact portion moves away from the other clamping block as the push block slides. Further, the side of the clamping block including the contact portion away from the push block includes an elastic member, which is disposed between the substrate and the clamping block including the contact portion, for providing a force to reset the clamping block including the contact portion.
[0080] Specifically, refer to Figure 4 and combined Figure 5a , Figure 5b As shown, in this embodiment, the clamping structure is disposed on the substrate 20. The substrate 20 includes a push block 21 that serves as a driving member and can be slidably disposed relative to the substrate 20. The clamping structure includes a first clamping block 22 and a second clamping block 23 disposed opposite to each other. The structure and engagement method of the first clamping block 22 and the second clamping block 23 are as described in Embodiment 1 above, and will not be repeated here.
[0081] In this embodiment, the push block 21 is located between the first clamping block 22 and the second clamping block 23, and the sliding direction of the push block 21 is orthogonal in the plane to the product clamping direction of the clamping structure. The sidewall edges of the push block 21 each include a groove 211. The first clamping block 22 and the second clamping block 23 each include contact portions 221 and 231 located within the groove 211. The groove 211 includes an inclined pushing surface 2111. As the push block 21 slides, the contact portions 221 of the first clamping block 22 and 231 of the second clamping block 23 abut against the inclined pushing surface 2111 and move along the inclined pushing surface 2111. The first clamping block 22 and the second clamping block 23 have a tendency to move away from each other. That is, in the initial state, the first clamping block 22 and the second clamping block 23 are in a first working state where they are close to each other. In this first working state, the first clamping surface and the second clamping surface are in a cooperative state that can clamp and fix the product. When it is necessary to clamp the product, push the push block 21 to slide, and both the first clamping block 22 and the second clamping block 23 are driven. The first clamping block 22 and the second clamping block 23 move away from each other and enter the second working state. In the second working state, the product can be clamped, released, or replaced.
[0082] In this embodiment, the sliding grooves 211 included on the sidewall edges of the push block 21 are mirror-symmetrically arranged with respect to the push block 21. The two sliding grooves 211 are at the same height in the Y direction shown in the figure. When the contact portion 221 of the first clamping block 22 and the contact portion 231 of the second clamping block 23 abut against the inclined pushing surface 2111 and move along the inclined pushing surface 2111, the first clamping block 22 and the second clamping block 23 move away from each other synchronously. In an optional embodiment, the sliding grooves included on the sidewall edges of the push block can also be located at different positions, and the position of the inclined pushing surface is different. As the push block slides, the contact portions of the first clamping block and the second clamping block abut against the inclined pushing surface in sequence, that is, the first clamping block and the second clamping block will exhibit sequential movement, moving away from the sides of the push block respectively, thereby adapting to and satisfying different working conditions and producing corresponding technical effects. This utility model does not limit this.
[0083] refer to Figure 5a , Figure 5bAs shown, in this embodiment, the first clamping block 22 includes a base portion 222 that is fixed to the substrate 20 via a guide rail; the second clamping block 23 includes a base portion 232 that is fixed to the substrate 20 via a guide rail.
[0084] Optionally, in a preferred embodiment, the first clamping block 22 includes a base portion 222 fixed to the substrate 20 via a guide rail, and a clamping portion 223 fixed to the base portion 222, with a first clamping surface formed on the clamping portion 223. The second clamping block 23 includes a base portion 232 fixed to the substrate 20 via a guide rail, and a clamping portion 233 fixed to the base portion 232, with a second clamping surface formed on the clamping portion 233. The clamping distance between the clamping portion 223 of the first clamping block 22 and the clamping portion 233 of the second clamping block 23 can be adjusted according to the width of the product being measured relative to the base portion; this embodiment does not impose any limitation on this.
[0085] Furthermore, in this embodiment, the side of the first clamping block 22 facing away from the push block 21 includes a first elastic member. This first elastic member is disposed between the substrate 20 and the first clamping block 22. Preferably, the first elastic member is disposed between the base portion of the first clamping block 22 and the substrate 20. When the push block 21 moves in the opposite direction and returns to its original position, and the inclined pushing surface 2111 no longer abuts against the contact portion 221 of the first clamping block 22, the first elastic member can provide a force to force the first clamping block 22 to reset. Similarly, the side of the second clamping block 23 facing away from the push block 21 includes a second elastic member. This second elastic member is disposed between the substrate 20 and the second clamping block 23. Preferably, the second elastic member is disposed between the base portion of the second clamping block 23 and the substrate 20. When the push block 21 moves in the opposite direction and returns to its original position, and the inclined pushing surface 2111 no longer abuts against the contact portion of the second clamping block 23, the second elastic member can provide a force to force the second clamping block 23 to reset.
[0086] In a preferred embodiment, the first clamping block 22, the second clamping block 23, and the pusher block 21 are respectively connected to the base plate 20 via guide rails. With this arrangement, the guide rails can provide accurate guidance for the movement of the first clamping block, the second clamping block, and the pusher block, and the direction of force is more precise due to the specification of the guide rails.
[0087] Combination Figure 5a , Figure 5bAs shown, exemplarily, the product is labeled with conductive component 90 as an example. The substrate includes a placement plate 24 for placing the product (i.e., conductive component 90). The placement plate 24 has a missing portion 241 at a position corresponding to the clamping surface of the clamping structure, so that the part of the product (i.e., conductive component 90) corresponding to the missing portion 241 is suspended. This facilitates clamping and fixing of the product by the clamping surface of the clamping structure without affecting the stability of the product placed on the placement plate. Preferably, the placement plate includes a limiting structure to limit the product placement position, so as to ensure that the initial placement position of the product does not deviate significantly.
[0088] Example 3
[0089] In one implementation, reference Figure 6a , Figure 6b As shown, this embodiment provides a fixture including a base plate 30 and two sets of clamping structures disposed on the base plate 30. Each of the two sets of clamping structures includes a push block 31 that can slide relative to the base plate 30. The fixture also includes a linkage structure mounted on the base plate 30. This linkage structure is connected to the push blocks 31 of the two sets of clamping structures. The linkage structure simultaneously drives the push blocks 31 of both sets of clamping structures to slide. The push blocks of the two sets of clamping structures, driven simultaneously by the linkage structure, can synchronously drive the two sets of clamping structures to clamp and position the product or to release it. The structure and engagement method of the clamping structures, the first clamping block, and the second clamping block can be referred to the above embodiments and will not be repeated here.
[0090] Specifically, in this embodiment, the product is exemplarily labeled as conductive component 90. The two sets of clamping structures clamp the product (i.e., conductive component 90) in the same direction. The linkage structure is a drive handle 32 whose two ends are respectively connected and fixed to the push blocks 31 of the two sets of clamping structures. An elastic member 33 is included between the drive handle 32 and the substrate 30. The elastic member 33 is used to provide a force to force the drive handle 32 to reset. The operator can operate the drive handle 32 with one hand to push the push blocks 31. The two push blocks 31 slide synchronously relative to the substrate 30. The clamping blocks of the two sets of clamping structures move away from each other under the synchronous action of the two push blocks 31. At this time, the operator, robot, or other feeding device places the product transferred here onto the substrate. The product is located at the clamping station of the clamping structure. The operator releases the drive handle, which retracts and resets under the action of the elastic component. At the same time, the drive handle drives the push blocks of the two sets of clamping structures to retract and reset. At this time, the first clamping block and the second clamping block in the two sets move closer to each other by the reset force provided by the first elastic component and the reset force provided by the second elastic component, thereby correcting and adjusting the position of the product and finally clamping and fixing the product for subsequent testing.
[0091] Furthermore, the fact that the two sets of clamping structures clamp the product in the same direction means that, within the plane, both sets of clamping structures clamp the product along the X-direction or both along the Y-direction. This allows for clamping of different parts of the product in the same clamping direction, thereby correcting and rectifying deformations in different parts of the product. (Refer to...) Figure 6a , Figure 6b The two sets of clamping structures shown clamp the product in the X direction.
[0092] Example 4
[0093] In one implementation, combined Figure 1 And refer to Figure 7a , Figure 7b As shown, this embodiment provides a fixture including a substrate 40 and two sets of clamping structures disposed on the substrate 40; the first clamping structure 41 clamps along a first direction, and the second clamping structure 42 clamps along a second direction different from the first direction. In this embodiment, the fixture is orthogonally arranged in the plane of the first direction (X direction) and the second direction (Y direction).
[0094] The push block includes a first push block 411 located between the two clamping blocks of the first clamping structure 41, and a second push block 421 located between the two clamping blocks of the second clamping structure 42. The sliding direction of the first push block 411 is along the second direction (Y direction), and the sliding direction of the second push block 421 is along the first direction (X direction).
[0095] The linkage structure includes: a wedge block 43 located at the end of the first push block 411 near the second push block 421; the wedge block 43 includes a contact surface 431; the contact surface 431 is inclined relative to the first direction and the second direction. A toggle member 44 is located on the second push block 421; the toggle member 44 abuts against the contact surface 431 on the wedge block 43. By abutting against the contact surface 431 with the toggle member 44, when the first push block 411 slides along the second direction, the second push block 421 can slide along the first direction under the drive of the first push block 411.
[0096] When products with large structural deformations are transferred, structural deformations in the X and Y planes often occur. For example, two adjacent product segments that are set at right angles or specific angles may lose their original structural state due to external pressure during transport. Alternatively, the product may experience end warping or local bending in the Z direction. This embodiment provides a fixture structure with two sets of clamping structures that clamp the product in different directions. The first and second clamping blocks of each set can clamp and fix the product from both sides of the corresponding product section. By using clamping structures in different directions to exert forces on the product in the X and Y directions, the various structural deformations of the product in the X and Y planes can be actively corrected during clamping. This is especially useful for products consisting of two adjacent product segments set at right angles or specific angles. The two sets of clamping structures clamp and fix the product from different directions. By utilizing the standardized matching positional relationship between the clamping structures, the product can be restored to its initial original structure during clamping without damage.
[0097] Furthermore, a first elastic member is included between the first pusher 411 and the substrate 40, the first elastic member exerting force in a second direction to provide a force that forces the first pusher to reset. A second elastic member is included between the second pusher 421 and the substrate 40, the second elastic member exerting force in a first direction to provide a force that forces the second pusher to reset.
[0098] In one embodiment, the actuating element 44 includes, but is not limited to, a roller, a bearing, or other rotating element that can be driven by the abutment surface 431. In this embodiment, the actuating element 44 is a bearing, and rolling friction is formed between the surface of the actuating element 44 and the abutment surface 431. In this embodiment, the bearing surface abuts against the abutment surface 431. Since the bearing can rotate around its own axis, when the first push block 411 slides along the second direction, the bearing rotates around its own axis on the abutment surface 431 during the movement. The second push block 421 slides along the first direction with the rolling of the bearing, thereby driving the two clamping blocks of the second clamping structure away. Rolling friction is formed between the abutment surface 431 and the bearing. This rolling friction reduces the resistance between the two, allowing the abutment surface 431 to drive the second push block 421 to move along the first direction more smoothly and reliably during the movement of the first push block 411, ensuring the reliability and stability of the drive of the first push block 411 to the second push block 421.
[0099] Example 5
[0100] Combined with appendix Figure 9 As shown, Figure 9This diagram illustrates a conductive component used in a product under test. This conductive component is a type of electrical connector frequently used in electronic products for connecting components at different locations. This electrical connector has multiple contact terminals facing different directions depending on the connection orientation, such as... Figure 9 As shown, its overall structure has two bent parts and three sides 901, 902, and 903. This type of electrical connector is characterized by its small size, thin and flat structure, and large deformation. During the circulation process, deformation can easily occur between the three sides, making it unsuitable for fixing by existing external clamping or internal pushing clamping structures.
[0101] In one implementation, reference Figure 8a , Figure 8b As shown, this embodiment provides a fixture, which includes a base plate 50 and three sets of clamping structures as described above disposed on the base plate 50. The clamping directions of the first clamping structure 51 and the second clamping structure 52 are along a first direction, and the clamping direction of the third clamping structure 53 is along a second direction different from the first direction. Each of the three clamping structures includes a push block. Specifically,
[0102] The push block includes: a first push block 511 located between the two clamping blocks of the first clamping structure 51; a second push block 521 located between the two clamping blocks of the second clamping structure 52; and a third push block 531 located between the two clamping blocks of the third clamping structure 53.
[0103] The fixture also includes a linkage structure mounted on the base plate 50; the linkage structure can link the first push block 511, the second push block 521, and the third push block 531 in a first direction and a second direction. The first clamping structure 51, the second clamping structure 52, and the third clamping structure 53 can be driven simultaneously through the linkage structure to clamp and position or release the product.
[0104] Specifically, in the fixture, the clamping directions of the first clamping structure 51 and the second clamping structure 52 are along a first direction (X direction), and the clamping direction of the third clamping structure 53 is along a second direction (Y direction) orthogonal to the first direction. The first clamping structure 51 clamps and fixes the first side 901 of the conductive component 90, the second clamping structure 52 clamps and fixes the third side 903 of the conductive component, and the third clamping structure 53 clamps and fixes the second side 902 of the conductive component. Each of the three clamping structures includes a first clamping block and a second clamping block arranged opposite to each other. Each clamping structure clamps and fixes the conductive component from both sides of the main body through the first clamping block and the second clamping block, that is, clamping and positioning the product from six directions. It should be noted that the structure and cooperation method of the three clamping structures and the first and second clamping blocks included in the clamping structures can be referred to the above embodiments, and will not be repeated here.
[0105] During the clamping process of the first and second clamping surfaces of each clamping structure, the regularized surface of the first clamping block restricts the conductive component in the vertical direction (Z direction) during clamping. As the first clamping block moves closer to the second clamping block, the regularized surface can cooperate with the first clamping surface to form a groove-shaped structure, constraining the conductive component in the vertical direction from the initial stage of contact with the conductive component body. The conductive component can be clamped in the correct position by the first and second clamping surfaces. In particular, if the conductive component undergoes slight deformation during handling, the cooperation of the regularized surface, the first clamping surface, and the second clamping surface during clamping automatically regularizes the conductive component itself and its position in the X, Y, and Z directions, enabling it to be accurately clamped and fixed.
[0106] This embodiment provides a fixture structure with a third clamping structure 53 having a different clamping direction than the first clamping structure 51 and the second clamping structure 52. The standardized matching positional relationship between the three sets of clamping structures can correct the structural shape of conductive parts that are deformed under the influence of external force during the transfer and transportation process. That is, when the product is clamped by the two clamping blocks of each of the three sets of clamping structures from both sides of the conductive part, the three sets of clamping structures will first regulate the shape and position of the first side 901, the second side 902 and the third side 903 of the conductive part in the X, Y and Z directions respectively. In addition, during this process, the relative position between the first side 901, the second side 902 and the third side 903 of the conductive part will also be corrected. For example, when the angles of the bends between the first side 901 and the third side 903 of the conductive component, and the angles of the bends between the second side 902 and the third side 903, are deformed by external forces during product flow, the angles of the aforementioned bends of the conductive component can be corrected to the angles required by the initial design by utilizing the standardized matching positional relationship between the three sets of clamping structures. Using this technology, the problem of slight deformation of the product during the positioning and inspection process can be corrected, eliminating the need for additional quality inspection devices to correct and straighten the product. The inspection operation is convenient and can be used in automated production lines, resulting in lower production costs.
[0107] In this embodiment, the linkage structure includes a drive handle 32, a wedge block 43, and a toggle member 44, which are respectively connected and fixed to the first push block 511 and the second push block 521. The drive handle 32 simultaneously drives the first push block 511 and the second push block 521 to slide. The wedge block 43 is located at the end of the first push block 511 and / or the second push block 521 near the third push block 531. The wedge block 43 includes a contact surface 431, which is inclined relative to the first direction and the second direction. The toggle member 44 is located on the third push block 531. The toggle member 44 abuts against the contact surface 431. When the first push block 511 and the second push block 521 slide along the second direction, the third push block 531 can slide under the drive of the first push block 511 and / or the second push block 521.
[0108] Specifically, refer to Figure 8a Figure 8b As shown, in the linkage structure, there are two wedge blocks 43. The two wedge blocks 43 are respectively disposed at the ends of the first push block 511 and the second push block 521 near the third push block 531. Each wedge block 43 includes a contact surface 431, which is inclined relative to the first and second directions. It can be understood that by providing wedge blocks 43 on both the first push block 511 and the second push block 521, the third push block 531 can be driven to move along the first direction simultaneously in a more stable manner, reducing the defects of insufficient driving force and unstable driving mode caused by a single driving point.
[0109] Corresponding to the wedge block 43, the third push block 531 also has two actuating elements 44. The two actuating elements 44 correspond to the two wedge blocks 43 respectively. The actuating elements 44 abut against the abutting surface 431. When the first push block 511 and the second push block 521 slide along the second direction, the third push block 531 can slide along the first direction under the simultaneous drive of the first push block 511 and the second push block 521.
[0110] Furthermore, in this embodiment, the first push block 511 and the second push block 521 each include a limiting block 5111, and the substrate 50 includes a limiting edge 501. In the initial state, the first clamping block and the second clamping block of the three sets of clamping structures are located in a first working state close to each other. In this first working state, the limiting block 5111 abuts against the limiting edge 501. After the product is clamped, the drive handle 32 is released. The first push block 511 and the second push block 521 are reset under the action of the elastic component between the drive handle 32 and the substrate 50. The third push block 531, which loses the force of the first push block 511 and the second push block 521, can be reset under the action of the second elastic component. The limiting block 5111 abuts against the limiting edge 501 to limit the position of the first push block 511 and the second push block 521 in the initial state. After the drive handle 32 is released, it can prevent the opposite end faces of the first clamping block and the second clamping block in the first clamping structure 51 and the second clamping structure 52 from being damaged by inertial impact.
[0111] In conjunction with the above, one aspect of the clamping structure provided by this utility model is that, during the clamping process of the first clamping surface and the second clamping surface clamping the product from both sides, the regularized surface can restrict the product in the vertical direction during clamping. As the first clamping block moves closer to the second clamping block, the regularized surface can cooperate with the first clamping surface to limit the product's position, ensuring that the product is clamped in the corrected position by the first and second clamping surfaces. This is particularly suitable for electrical connector products that are small in size, thin and flat in structure, have a large amount of structural deformation, and may experience slight deformation during handling.
[0112] In another aspect, the fixture provided by this utility model, which includes the above-mentioned clamping structure, utilizes multiple clamping structures arranged in different directions. A single clamping structure clamps the product from both sides, which can neatly position the product during the clamping process. Furthermore, by utilizing the clamping structures in different directions, forces are applied to the product in the X and Y directions, which can correct the deformation of the product in the plane and restore it to its initial design structural state.
