Description

Technical Field

[0001] The present invention belongs to the field of panel testing, and more specifically, relates to a double-linkage crimping fixture and testing equipment. Background Art

[0002] The panel inspection industry typically conducts multi-functional, multi-station testing on panel products. To better protect these products, they are typically secured on a carrier, which carries them through various stations on the factory assembly line for testing. To prevent damage from falling or sliding off the carrier, the carrier is typically equipped with stoppers to secure the product in place, providing enhanced protection.

[0003] Current methods for locking screens with positioners all rely on independent mechanisms. For example, a carrier typically has two sets of positioners (such as buckles) that move independently. This requires workers to use both hands to open or close the positioners, resulting in low testing efficiency. In automated production lines, two additional mechanisms are required to synchronize the opening and closing of the two positioners, increasing hardware costs and further complicating the automation line. Summary of the Invention

[0004] In response to the above defects or improvement needs of the prior art, the present invention provides a double-linkage crimping fixture and testing equipment, the purpose of which is not only to fix the panel product on the base plate, but also to realize the linkage of the two positioning tongues with one hand, thereby reducing the intensity and steps of manual work and improving testing efficiency.

[0005] In a first aspect, the present invention provides a double-linkage crimping jig, the double-linkage crimping jig comprising a base plate, a crimping member, and a double-linkage limiting member;

[0006] The crimping piece is located on the bottom plate to crimp the conductive product;

[0007] The double-linked limit member includes two positioning tongues, a connecting rod and a rotating shaft. The two positioning tongues are arranged at intervals, and both positioning tongues can be slidably arranged on the base plate to clamp products with the base plate respectively. An elastic member is clamped between each positioning tongue and the base plate to drive the positioning tongue to slide toward the product. One positioning tongue is transmission-connected to one end of the connecting rod, and the rotating shaft is located between the two positioning tongues. The middle part of the rotating shaft is hinged on the base plate, and one end of the rotating shaft is rotatably matched with the other end of the connecting rod, and the other end of the rotating shaft is against the other positioning tongue.

[0008] Optionally, the double-link limiting member further includes a cam block, which is slidably arranged on the bottom plate, and the sliding direction of the cam block is perpendicular to the bottom plate. The top of one of the positioning tongues has an inclined surface, and the cam block abuts against the inclined surface to drive the inclined surface to slide away from the product.

[0009] Optionally, a first bearing is arranged on the side surface of the cam block facing the inclined surface, and the first bearing abuts against the inclined surface.

[0010] Optionally, a first housing is provided on the bottom plate. One of the positioning tongues is slidably arranged in the first housing, and the tongue portion of one of the positioning tongues extends out of the first housing. An elastic member is clamped between one of the positioning tongues and the inner wall of the first housing. A through hole is provided at the top of the first housing, and the cam block is slidably inserted into the through hole.

[0011] Optionally, the double-link limiting member further includes a push block, which has two parallel and spaced protrusions. The two protrusions respectively abut against the other positioning tongue, and the push block is hinged to the other end of the rotating shaft.

[0012] Optionally, the two protrusions are symmetrically arranged about the center of the other positioning tongue, and the side surface of each protrusion facing the other positioning tongue is an arc surface.

[0013] Optionally, a positioning block is provided at the bottom of one of the positioning tongues, and a positioning groove is provided at one end of the connecting rod. The positioning block is inserted into the positioning groove.

[0014] Optionally, a groove is provided at the other end of the connecting rod, and one end of the rotating shaft is rotatably inserted into the groove, and the rotating shaft and the groove are in clearance fit.

[0015] Optionally, a plurality of spaced second bearings are inserted on the connecting rod, and the outer edge of the second bearing abuts against the bottom plate.

[0016] In a second aspect, the present invention further provides a testing device, which includes a double-link crimping fixture as described in the first aspect.

[0017] The beneficial effects brought by the technical solutions provided by the embodiments of the present invention are:

[0018] For a double-linkage crimping jig provided by an embodiment of the present invention, before the product needs to be subjected to a crimping test, first, the left positioning tongue piece is driven by an external force to slide away from the right positioning tongue piece (overcoming the elastic force of the elastic member). During the movement of the left positioning tongue piece, the connecting rod will be driven to slide. After the connecting rod slides, one end of the connecting rod will be pulled to rotate clockwise. According to the lever principle, the other end of the connecting rod will also rotate clockwise and generate a corresponding acting force, so that the right positioning tongue piece overcomes the elastic force of the elastic member and slides away from the left positioning tongue piece. In this way, the two positioning tongue pieces can both slide away from each other (that is, the two positioning tongue pieces are synchronously opened). Therefore, the linkage of the two positioning tongue pieces can be realized with one hand. At this time, the panel product can be placed between the two positioning tongue pieces. Then, the acting force on the left positioning tongue piece is released, and the elastic member will drive the two positioning tongue pieces to slide towards each other (that is, the two positioning tongue pieces are synchronously closed), and the two positioning tongue pieces will protrude to clamp the product panel. In this way, the panel product can be fixed during the test and subsequent handling to other workstations, avoiding the panel product from falling. In addition, when the panel product needs to be tested, the product panel can be conducted through the crimping member at the corresponding workstation.

[0019] Similarly, when the product needs to be removed, the left positioning tongue piece is driven again to slide away from the right positioning tongue piece, and the synchronous opening of the two positioning tongue pieces can be realized. At this time, the panel product can be taken out.

[0020] That is to say, a double-linkage crimping jig provided by the present invention can not only fix the panel product on the bottom plate, but also realize the linkage of the two positioning tongue pieces with one hand, thereby reducing the manual operation intensity and steps and improving the test efficiency.

DETAILED DESCRIPTION

[0026] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0027] Figure 1 Schematic diagram of the structure of a double-linkage crimping fixture provided by an embodiment of the present invention. Figure 1 As shown, the double-linkage crimping fixture includes a base plate 1 , a crimping member 2 and a double-linkage limiting member 3 .

[0028] The crimping piece 2 is located on the base plate 1 to crimp the conductive product.

[0029] Figure 2 Schematic diagram of the structure of the double linkage limiter provided by the embodiment of the present invention. Figure 2 As shown, the double-linkage limiter 3 includes two positioning tongues 31, a connecting rod 32 and a rotating shaft 33. The two positioning tongues 31 are arranged at intervals, and both positioning tongues 31 can be slidably arranged on the base plate 1 to clamp products with the base plate 1 respectively. An elastic member 34 is clamped between each positioning tongue 31 and the base plate 1 to drive the positioning tongue 31 to slide toward the product. One positioning tongue 31 is transmission-connected to one end of the connecting rod 32, and the rotating shaft 33 is located between the two positioning tongues 31. The middle part of the rotating shaft 33 is hinged to the base plate 1, and one end of the rotating shaft 33 is rotatably matched with the other end of the connecting rod 32, and the other end of the rotating shaft 33 is against the other positioning tongue 31.

[0030] For a double-linkage crimping jig provided by an embodiment of the present invention, before the product needs to be crimped and tested, first, the left positioning tongue piece 31 is driven by an external force to slide away from the right positioning tongue piece 31 (overcoming the elastic force of the elastic member 34). During the movement of the left positioning tongue piece 31, the connecting rod 32 will be driven to slide. After the connecting rod 32 slides, one end of the connecting rod 32 will be pulled to rotate clockwise. According to the lever principle, the other end of the connecting rod 32 will also rotate clockwise and generate a corresponding acting force, so that the right positioning tongue piece 31 overcomes the elastic force of the elastic member 34 and slides away from the left positioning tongue piece 31. In this way, the two positioning tongue pieces 31 can both slide away from each other (that is, the two positioning tongue pieces 31 are synchronously opened). Therefore, the linkage of the two positioning tongue pieces 31 can be realized with one hand. At this time, the panel product can be placed between the two positioning tongue pieces 31. Then, the acting force on the left positioning tongue piece 31 is released, and the elastic member 34 will drive the two positioning tongue pieces 31 to slide towards each other (that is, the two positioning tongue pieces 31 are synchronously closed), and the two positioning tongue pieces 31 will protrude to clamp the product panel. In this way, the panel product can be fixed during the test and the subsequent handling to other workstations, avoiding the dropping of the panel product. In addition, when the panel product needs to be tested, the product panel can be conducted through the crimping member 2 at the corresponding workstation.

[0031] Similarly, when the product needs to be removed, the left positioning tongue piece 31 is driven again to slide away from the right positioning tongue piece 31, and the synchronous opening of the two positioning tongue pieces 31 can be realized. At this time, the panel product can be taken out.

[0032] That is to say, a double-linkage crimping jig provided by the present invention can not only fix the panel product on the base plate 1, but also realize the linkage of the two positioning tongue pieces 31 with one hand, thereby reducing the manual operation intensity and steps and improving the test efficiency.

[0033] In addition, in an automated production line, only an additional mechanism needs to be added to drive the positioning tongue piece 31 to slide to realize the synchronous opening or synchronous closing of the two positioning tongue pieces 31, avoiding increasing the hardware cost and making the automated line body simpler.

[0034] Exemplarily, the two positioning tongue pieces 31 are located on both sides of the panel product, so that the clamping of the panel product is more stable and not easy to fall off.

[0035] It is easy to understand that the positioning tongue piece 31 includes a body part and a tongue piece part. The body part is slidably matched with the base plate 1, and the tongue piece part is located at the top of the body part and protrudes from the body part, so as to cooperate with the base plate 1 to clamp the panel product.

[0036] In this embodiment, the double-linkage limiting member 3 further includes a cam block 35. The cam block 35 is slidably arranged on the bottom plate 1, and the sliding direction of the cam block 35 is perpendicular to the bottom plate 1. The top of one positioning tongue 31 has an inclined surface 311, and the cam block 35 abuts against the inclined surface 311 to drive the inclined surface 311 to slide away from the product.

[0037] In the above embodiment, by pressing the cam block 35 downward, the downward movement of the cam block 35 can be converted into the sliding of the positioning tongue 31, which makes the application of force more convenient.

[0038] Exemplarily, a first bearing 351 is provided on the side surface of the cam block 35 facing the inclined surface 311. The first bearing 351 abuts against the inclined surface 311, and by squeezing the positioning tongue 31 through the first bearing 351, the friction force can be effectively reduced.

[0039] Exemplarily, the number of the first bearings 351 can be two.

[0040] Combined with Figure 1 and Figure 2 As shown, the bottom plate 1 has a first housing 11. One positioning tongue 31 is slidably arranged in the first housing 11, and the tongue portion of one positioning tongue 31 extends out of the first housing 11. An elastic member 34 is clamped between one positioning tongue 31 and the inner wall of the first housing 11. The top of the first housing 11 has a through hole 111, and the cam block 35 is slidably inserted into the through hole 111.

[0041] In the above embodiment, the first housing 11 can not only guide the cam block 35 (through the through hole 111), but also protect the positioning tongue 31 to prevent the positioning tongue 31 from sliding accidentally.

[0042] Exemplarily, the first housing 11 also has a sliding hole (not shown in the figure), and the tongue portion is slidably inserted into the sliding hole. When the left positioning tongue 31 moves leftward against the elastic force of the elastic member 34, the tongue portion is retracted into the first housing 11 through the sliding hole. At this time, the panel product can be taken and placed; when the left positioning tongue 31 moves rightward under the action of the elastic member 34, the tongue portion extends out of the first housing 11, thereby realizing the clamping of the panel product.

[0043] Exemplarily, the elastic member 34 can be a spring.

[0044] Figure 3 is the top view of the double-linkage limiting member provided by the embodiment of the present invention. Combined with Figure 2 and Figure 3 As shown, the double-linkage limiting member 3 further includes a push block 36. The push block 36 has two parallel and spaced-apart protrusions 361, and the two protrusions 361 respectively abut against the other positioning tongue 31. The push block 36 is hinged to the other end of the rotating shaft 33.

[0045] In the above embodiment, the pushing block 36 can drive the two protrusions 361 to uniformly press the right positioning tongue piece 31, avoiding the problem of concentrated force generated by directly driving with the rotating shaft 33. In addition, the other ends of the pushing block 36 and the rotating shaft 33 are also hinged, and the rotation of the rotating shaft 33 can be converted into the linear motion of the pushing block 36.

[0046] Exemplarily, the two protrusions 361 are symmetrically arranged along the center of the other positioning tongue piece 31, and the side surfaces of the protrusions 361 facing the other positioning tongue piece 31 are arc surfaces, so as to facilitate uniform action on the right positioning tongue piece 31. On the basis of the hinge of the pushing block 36, by setting the contact surface of the protrusion 361 as an arc surface, the acting force direction of the protrusion 361 on the positioning tongue piece 31 can be adjusted to the sliding direction of the positioning tongue piece 31, making the sliding of the right positioning tongue piece 31 smoother.

[0047] In this embodiment, the bottom of one positioning tongue piece 31 has a positioning block 312, and one end of the connecting rod 32 has a positioning groove 321, and the positioning block 312 is inserted into the positioning groove 321.

[0048] In the above embodiment, the transmission cooperation between the positioning tongue piece 31 and the connecting rod 32 can be conveniently realized through the insertion and cooperation of the positioning block 312 and the positioning groove 321.

[0049] Exemplarily, the other end of the connecting rod 32 has a groove 322, and one end of the rotating shaft 33 is rotatably inserted into the groove 322, and the rotating shaft 33 and the groove 322 are in clearance fit. Through the clearance fit between the rotating shaft 33 and the groove 322, the sliding of the connecting rod 32 can be converted into the rotation of the rotating shaft 33, so as to realize the synchronous drive of the right positioning tongue piece 31.

[0050] In this embodiment, the rotation of the rotating shaft 33 and the hinge of the pushing block 36 are both realized through a pin shaft.

[0051] Exemplarily, a plurality of second bearings 323 arranged at intervals are inserted on the connecting rod 32, and the outer edges of the second bearings 323 are abutted against the bottom plate 1, so that the friction force received during the sliding of the connecting rod 32 can be effectively reduced through the second bearings 323.

[0052] Exemplarily, the number of the second bearings 323 can be 5.

[0053] It should be noted that in this embodiment, the connecting rod 32, the rotating shaft 33 and the pushing block 36 are all arranged inside the bottom plate 1, so as to reduce the space occupied by the whole device, and the connecting rod 32, the rotating shaft 33 and the pushing block 36 can also be protected.

[0054] The embodiment of the present invention also provides a testing device, and the testing device includes a double-linkage crimping jig as described above.

[0055] Those skilled in the art can easily understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
