Abstract
Description
Technical Field
[0001] This invention applies to the technical field of ribbon cable positioning, and particularly relates to a right-angle ribbon cable positioning test mechanism. Background Technology
[0002] In the continuous upgrading and iteration of modern electronic products, the demand for diverse functions leads to space constraints for each product. As a result, the research and development and layout of internal components are extremely complex and precise. Naturally, the design of internal components in electronic products often uses connectors with 90° bent ribbon cables. This design not only enables functional connections with other components but also reduces space occupation. However, these 90° bent ribbon cable connectors need to undergo functional testing to ensure that the component is working properly before proceeding to the next assembly step.
[0003] For 90° bent ribbon cables, the biggest challenge lies in feeding and positioning. If the holder position is fixed, due to significant product tolerance variations and inherent errors in the robotic arm's feeding accuracy, the ribbon cable is highly susceptible to colliding with the holder during feeding, leading to product damage. Therefore, proper feeding is the first major challenge in testing this type of 90° ribbon cable. The holder for positioning the ribbon cable must be designed to avoid certain space, facilitating robotic arm feeding. After solving the feeding problem, the second issue is positioning and pre-pressing the ribbon cable. Because the B2B connector on the ribbon cable requires pin insertion, positioning is crucial. Designing a positioning mechanism within limited space is both critical and difficult. Most common ribbon cables are horizontal, allowing feeding and positioning to be directly accomplished through the holder's positioning features. However, this method cannot be directly applied to 90° bent ribbon cables. If a simple right-angle ribbon cable positioning test mechanism can be designed that can vertically position right-angle ribbon cables and has a linkage pre-compression mechanism to ensure product positioning accuracy, the above problems can be solved. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a right-angle ribbon cable positioning test mechanism with a simple structure, capable of vertically cutting and positioning right-angle ribbon cables, and equipped with a linkage pre-compression mechanism to ensure product positioning accuracy.
[0005] The technical solution adopted in this invention is as follows: This invention includes a positioning cylinder, a fixture base plate, and a cable positioning module. The cable positioning module includes a movable connecting plate and a positioning block. The movable connecting plate slides with the lower end face of the fixture base plate via several side-pushing slide rails. The positioning block is disposed at one end of the sliding connecting block. The positioning cylinder drives the positioning block to cooperate with the product on the feed port of the fixture base plate. A pre-compression module is provided on the movable connecting plate, and the pre-compression module cooperates with the limiting end of the positioning block.
[0006] Furthermore, the pre-compression module includes a pre-compression base, a pre-compression block top rod, a hinge connecting rod block, and a pre-compression block. The pre-compression base is connected to the upper surface of the movable connecting plate. The pre-compression base is provided with a sliding adjustment groove. The sliding shaft at one end of the hinge connecting rod block is slidably engaged with the sliding adjustment groove. The other end of the hinge connecting rod block is engaged with a limiting groove on the movable connecting plate. The pre-compression block top rod is connected to one side of the pre-compression base, and the pre-compression block top rod drives the pre-compression block to engage with the limiting end of the positioning pressure block.
[0007] Furthermore, the sliding end of the pre-compression block is slidably engaged with one side of the positioning block, a plurality of first floating springs are provided between the pre-compression block and the positioning block, and a plurality of second floating springs are provided between the pre-compression block and the top rod of the pre-compression block.
[0008] Furthermore, the positioning block is provided with a product contouring groove at its limiting end, and the pre-pressing block is provided with a pre-pressing side rod at its end, the pre-pressing side rod cooperating with the product in the product contouring groove.
[0009] Furthermore, product side pressure modules are provided on both sides of the fixture base plate. Each product side pressure module includes a side pressure base plate and a side pressure block. The two sets of side pressure base plates are respectively provided on both sides of the fixture base plate. The two sets of side pressure blocks are slidably engaged with the sliding groove structure on both sides of the fixture base plate. A plurality of side push springs are provided between the side pressure base plate and the side pressure block. The plurality of side push springs drive the two sets of side pressure blocks to engage with both sides of the main body of the product in the feed port.
[0010] Furthermore, the side pressure block is provided with a drive handle, which drives the side pressure block to cooperate with the side pressure base plate.
[0011] Furthermore, an adsorption head is provided on one side of the positioning block, and the adsorption head engages with the product in the product contour groove.
[0012] Furthermore, a positioning sensor is provided on the upper surface of the fixture base plate, and the positioning sensor is in sensing cooperation with the product in the feed port.
[0013] Furthermore, the movable connecting plate is provided with a plurality of limiting blocks, and the plurality of limiting blocks are matched with the corresponding side of the fixture base plate for limiting.
[0014] The beneficial effects of this invention are as follows: This invention solves the problem of feeding and positioning 90° bent ribbon cables through a cleverly designed linkage mechanism. Because this type of ribbon cable is very compact and can only be fed vertically, the cable holder must be designed to be movable without affecting the cable's positioning, ensuring no damage. Driven by a single actuator, the linkage mechanism opens the cable holder and pre-pressing block during feeding, providing sufficient space for vertical feeding. After feeding, the cable holder and pre-pressing block retract, pressing the cable into the positioning feature of the cable holder, thus completing the cable positioning. This positioning method not only reduces the cost of redundant actuators and structural design but also achieves the desired feeding and positioning effect, offering significant advantages.

Detailed Implementation
[0016] like Figures 1 to 5 As shown, in this embodiment, the present invention includes a positioning cylinder 1, a fixture base plate 2, and a cable positioning module 3. The cable positioning module 3 includes a movable connecting plate 31 and a positioning block 32. The movable connecting plate 31 slides with the lower end face of the fixture base plate 2 via several side-pushing slide rails 33. The positioning block 32 is disposed at one end of the sliding connecting plate 31. The positioning cylinder 1 drives the positioning block 32 to cooperate with the product on the feed port 4 on the fixture base plate 2. A pre-compression module 5 is disposed on the movable connecting plate 31, and the pre-compression module 5 cooperates with the limiting end of the positioning block 32. Therefore, this application uses only one set of positioning cylinders 1 to drive the actuating elements. Through the pre-compression module 5, the positioning block 32 and the pre-compression module 5 are opened during feeding, leaving sufficient space for vertical cable feeding. After feeding, the positioning block 32 and the pre-compression module 5 are simultaneously tightened to complete the cable positioning.
[0017] like Figures 3 to 5 As shown, in this embodiment, the pre-compression module 5 includes a pre-compression base 51, a pre-compression block top rod 52, a hinge connecting rod block 53, and a pre-compression block 54. The pre-compression base 51 is connected to the upper surface of the movable connecting plate 31. The pre-compression base 51 is provided with a sliding adjustment groove 55. The sliding shaft 56 at one end of the hinge connecting rod block 53 is slidably engaged with the sliding adjustment groove 55, and the other end of the hinge connecting rod block 53 is engaged with the limiting groove 34 on the movable connecting plate 31. The pre-compression block top rod 52 is connected to one side of the pre-compression base 51, and the pre-compression block top rod 52 drives the pre-compression block 54 to engage with the limiting end of the positioning pressure block 32. Therefore, the sliding engagement of the hinge connecting rod block 53 with the limiting groove 34 serves to limit the movement of the pre-compression block 54, preventing it from extending too far. In the feeding state, the pre-compression block 54 separates from the limiting end of the positioning pressure block 32, thus realizing the feeding operation.
[0018] like Figures 3 to 5 As shown, in this embodiment, the sliding end of the pre-compression block 54 is slidably engaged with one side of the positioning block 32. A plurality of first floating springs 6 are provided between the pre-compression block 54 and the positioning block 32, and a plurality of second floating springs 7 are provided between the pre-compression block 54 and the pre-compression block top rod 52. Therefore, the plurality of first floating springs 6 and the plurality of second floating springs 7 can achieve buffering and resetting functions, enabling the pre-compression block 54 and the pre-compression block top rod 52 to achieve linkage, realizing product loading and pre-compression.
[0019] like Figures 3 to 5 As shown, in this embodiment, the positioning block 32 has a product contouring groove 35 at its limiting end, and the pre-pressing block 54 has a pre-pressing side rod 57 at its end. The pre-pressing side rod 57 cooperates with the product in the product contouring groove 35. Therefore, when the pre-pressing side rod 57 is pushed to the side, a certain space is formed between it and the product contouring groove 35 for feeding. When the positioning block 32 is reset, several first floating springs 6 and several second floating springs 7 drive the pre-pressing side rod 57 to synchronously pre-press the product.
[0020] like Figure 1 and Figure 6As shown, in this embodiment, product side-pressing modules 8 are provided on both sides of the fixture base plate 2. Each product side-pressing module 8 includes a side-pressing base plate 81 and side-pressing blocks 82. The two sets of side-pressing base plates 81 are respectively disposed on both sides of the fixture base plate 2. The two sets of side-pressing blocks 82 are slidably engaged with the sliding groove structures on both sides of the fixture base plate 2. A plurality of side-push springs 83 are provided between the side-pressing base plates 81 and the side-pressing blocks 82. These side-push springs 83 drive the two sets of side-pressing blocks 82 to engage with both sides of the product body portion within the feed inlet 4. Therefore, the two sets of side-pressing blocks 82 press against both sides of the product body portion under the action of elastic force, achieving initial positioning of the product.
[0021] like Figure 6 As shown, in this embodiment, the side pressure block 82 is provided with a drive handle 84, which drives the side pressure block 82 to cooperate with the side pressure base plate 81. Therefore, the drive handle 84 drives the side pressure block 82 to open for loading.
[0022] like Figures 3 to 5 As shown, in this embodiment, an adsorption head 9 is provided on one side of the positioning block 32, and the adsorption head 9 is engaged with the product in the product contouring groove 35. Therefore, the product contouring groove 35 is provided with an adsorption hole that is connected and conductive to the adsorption head 9. When the adsorption head 9 is activated, it can stably adsorb the bent end of the product in the product contouring groove 35.
[0023] like Figure 1 As shown, in this embodiment, a positioning sensor 10 is provided on the upper surface of the fixture base plate 2, and the positioning sensor 10 is in contact with the product inside the feed inlet 4. Therefore, the positioning sensor 10 can sense the presence or absence of the product.
[0024] like Figure 1 As shown, in this embodiment, the movable connecting plate 31 is provided with a plurality of limiting blocks 11, which are matched with the corresponding side of the fixture base plate 2 for limiting. Therefore, the plurality of limiting blocks 11 can prevent the positioning cylinder 1 from extending too far, causing the cable positioning module 3 to over-align and affecting the feeding accuracy.
[0025] The working principle of this invention is as follows: Before the equipment is started, the movable end of the positioning cylinder 1 is in a retracted state, the end of the pre-pressure block top rod 52 abuts against the far end of the limiting groove 34, the pre-pressure block 54 extends relative to the positioning pressure block 34, the pre-pressure side rod 57 separates from the product contouring groove 35, the two sets of side pressure blocks 82 are opened, and the right-angle ribbon cable is placed into the feed port 4 at a vertical angle. The deflected end of the ribbon cable extends into the product contouring groove 35. The two sets of side pressure blocks 82 press the main body of the product under the action of elastic force. When the positioning sensor 10 senses the product, the movable end of the positioning cylinder 1 extends, and several sets of first floating springs 6 and several sets of second floating springs 7 drive the pre-pressure block 54 to reset. The pre-pressure block 54 presses the deflected end of the product into the product contouring groove 35 through the pre-pressure side rod 57 to achieve the pre-pressure positioning effect. After the test is completed, each component is reset, the right-angle ribbon cable to be positioned is replaced, and the above steps are repeated to achieve the linkage pre-pressure positioning of the right-angle ribbon cable.
[0026] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
