Description

Technical Field

[0001] This invention relates to the field of flexible flat cable testing technology, specifically to an automatic insertion and removal testing module for flexible flat cables. Background Technology

[0002] FPC stands for Flexible Printed Circuit, a type of printed circuit board made from a flexible substrate. Its characteristics include thinness and foldability. During manufacturing, polyimide is typically used as the substrate, with copper foil covering it and etched to form the circuitry. A cover film is then placed over the copper foil circuitry. This structure enables signal transmission and insulation protection. Reinforcing plates are used to bond specific areas, increasing strength and thickness, and facilitating insertion and installation. Additionally, the ends of FPC cables typically have gold-plated contacts, commonly known as gold fingers, for mating with connectors soldered onto the main circuit board. Users usually align the gold-fingered end of the cable with the connector and insert it into the connector. The connector's internal metal springs clamp the gold fingers to complete the electrical connection. An adhesive layer is applied between these layers to bond them together, thus forming the FPC cable.

[0003] Flexible printed circuit (FPC) cables are widely used in high-tech electronic products such as computers, mobile phones, watches, cameras, automotive electronics, and medical equipment. They are an important driving force for the advancement of electronic product technology. Therefore, the quality requirements for FPC cables are very high, and post-production testing is an essential step.

[0004] Manual testing is commonly used when testing flexible flat cables. When testing electrical performance, the gold fingers are manually inserted into a fixed test connector, and a multimeter and connected monitor are used to determine the continuity of the circuit. The connector is then removed. The testing operation is simple. However, considering practical use, manual testing has several problems. First, it is not suitable for batch testing due to its low efficiency. Second, this testing method relies on the user's skill and focus, which can easily lead to missed detections and misjudgments. Furthermore, manual testing carries the potential risk of physical damage; improper control of force and angle can easily damage the flexible flat cable, hindering efficient testing.

[0005] Therefore, there is an urgent need for an automatic plug-in / plug-out testing module for flexible flat cables to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic plug-in / plug-out test module for flexible flat cables to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic insertion and removal test module for flexible flat cables, comprising a machine base, a test bench, and several insertion and removal interfaces. A data processing terminal is provided on the exterior of the machine base. A first driving unit is mounted on one side of the upper surface of the machine base. The output end of the first driving unit is connected to an insertion and removal floating assembly. The insertion and removal floating assembly includes a mounting plate. A mounting groove is formed in the middle of the mounting plate. Protruding structures are integrally formed at the upper and lower ends of the mounting plate. Multiple connecting rods are connected through the interior of both sets of protruding structures. The connecting rods are connected to the protruding structures... A gap area is left between the internal surfaces. The side of the mounting plate facing the test bench is connected to a first auxiliary plate via a connecting rod. The first auxiliary plate and the mounting plate are initially separated by a certain distance. A second auxiliary plate is fixedly connected to the side of the first auxiliary plate facing the test bench. A second mounting slot is opened in the middle of the first auxiliary plate corresponding to the position of the first mounting slot. An adapter plate is provided in the internal contact between the first mounting slot and the second mounting slot. The adapter plate is fixedly connected to the first auxiliary plate through the bottom surface of the second mounting slot. A positioning pin is inserted into the bottom of the mounting plate. The positioning pin is connected to the signal of the data processing terminal.

[0008] The present invention further explains that the two ends of the adapter board are respectively fixedly connected to a first adapter part and a second adapter part. The second adapter part is located close to the plug-in interface, and the first adapter part is located away from the plug-in interface, for connecting with the flexible flat cable to be tested.

[0009] The present invention further illustrates that the bottom of the second auxiliary plate is provided with a pressing part and a guiding part. The bottom surface of the pressing part abuts against the adapter plate. The guiding part is provided on the side of the second auxiliary plate near the plug-in interface. The guiding part includes a front end, an inclined part and a bottom part. The bottom part is connected to the pressing part and forms a stepped shape. The horizontal plane of the bottom part is higher than the horizontal plane of the pressing part. The inclined part and the front end are sequentially opened at the front end of the pressing part.

[0010] The present invention further illustrates that the tilt angle of the inclined part relative to the horizontal plane is 30°-45°, and the connection between the inclined part and the bottom part is chamfered.

[0011] The present invention further illustrates that the connecting rod consists of a front part, a tail part, and a head. The head and the shaft of the front part are both located within the protruding structure of the mounting plate. A portion of the shaft of the tail part extends through the interior of the first auxiliary plate, and another portion of the shaft of the tail part is located within the space where the retention distance is located. The head is fixedly connected to the protruding structure.

[0012] The present invention further illustrates that a buffer structure is provided between the mounting plate and the first auxiliary plate. The buffer structure includes an elastic part fixedly connected to the tail of the rod. In the compressed state, the elastic part is entirely located inside the first auxiliary plate. A gasket is fixedly connected to the end of the elastic part away from the connecting rod. The gasket is in support contact with the inner wall of the second auxiliary plate. The diameter of the elastic part is not greater than the diameter of the connecting rod.

[0013] The present invention further illustrates that a support platform is fixedly installed on the upper surface of the machine tool by bolts. The side of the support platform away from the test platform is installed with a first drive unit. A transmission component is provided at the output end of the first drive unit. The first drive unit is connected to a connecting seat through the transmission component. A vertical plate is fixedly connected to the side of the connecting seat facing the test platform by bolts. A horizontal plate is fixedly connected to the lower end of the vertical plate by bolts. The vertical plate and the horizontal plate form an L-shaped structure. The side of the horizontal plate facing the test platform is connected to a pluggable floating component.

[0014] The present invention further illustrates that the transmission assembly includes a transmission block that is connected to the output end of the first drive unit. A slider is provided below the transmission block. Slide rails are slidably connected to the two side walls of the slider. A base plate is fixedly connected to the bottom of each slide rail. The base plate is fixedly connected to the support platform by bolts.

[0015] The present invention further explains that a third detection unit is connected between the adapter plate and the mounting plate. The third detection unit is used to detect the three-dimensional force to determine the floating situation of the adapter plate during the insertion and removal action.

[0016] The present invention further illustrates that a limit detection component is provided on one side of the connecting seat. The limit detection component includes a fixed seat fixedly connected to the outer wall of the slide rail on one side. A ranging sensor is fixedly installed on the upper surface of the fixed seat near the first driving part. A movable seat is slidably connected to the upper surface of the fixed seat away from the first driving part. At least one limiting groove is formed inside the movable seat on the side away from the first driving part. The limiting groove is arranged in a ring shape. A limiting rod is provided inside the limiting groove. The bottom of the limiting rod is fixedly connected to the fixed seat. A ranging movable part is fixedly connected to the upper surface of the movable seat on the side near the first driving part. A fixing member is fixedly connected between the ranging movable part and the connecting seat. The ranging sensor is signal-connected to the data processing terminal.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: By setting up a floating plug-in component, the present invention realizes automatic plug-in and plug-out testing of batch flexible flat cables, thereby replacing manual plug-in and plug-out operations.

Detailed Implementation

[0032] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] Please see Figure 1 The present invention provides a technical solution: an automatic plug-in / plug-out test module for flexible flat cables, including a machine base 1 and a test platform 2 installed in the middle of the machine base 1. Several plug-in / plug-out interfaces for testing flexible flat cables are arranged around the test platform 2. A data processing terminal (not shown in the figure) is set on the outside of the machine base 1 for executing instructions for automatic plug-in / plug-out testing of flexible flat cables and receiving and analyzing test data.

[0034] Further, see Figures 2-3 The machine base 1 has a hollow interior for easy cable installation. A support platform is bolted to the upper surface of the machine base 1. A first drive unit 3, using a bidirectional motor, is mounted on the side of the support platform away from the test platform 2. A transmission assembly 11 is installed at the output end of the first drive unit 3. A connecting seat 4 is connected to the first drive unit 3 via the transmission assembly 11. A vertical plate 6 is bolted to the side of the connecting seat 4 facing the test platform 2. The number of vertical plates 6 connected to the connecting seat 4 depends on the testing requirements and the size of the flexible cable test end. A horizontal plate 7 is bolted to the lower end of the vertical plate 6. Figure 2 As shown, the vertical plate 6 and the horizontal plate 7 form an L-shaped structure. The side of the horizontal plate 7 facing the test bench 2 is connected to a plug-in floating component, which has a certain position fine adjustment function during the automatic plug-in process.

[0035] When the first drive unit 3 starts in the forward direction, its output end will drive the connecting seat 4 to move in the same direction through the transmission component 11, thereby driving the vertical plate 6 and the horizontal plate 7 to move synchronously, so as to carry out the automatic insertion and removal test of the subsequent insertion and removal floating component.

[0036] Specifically, see Figure 4 The transmission assembly 11 includes a transmission block 111 that is connected to the output end of the first drive unit 3. A slider is provided below the transmission block 111. Slide rails 112 are slidably connected to the two side walls of the slider. A base plate 113 is fixedly connected to the bottom of each slide rail 112. The base plate 113 is fixedly connected to the support platform by bolts. When the connecting seat 4 moves, the slider follows the connecting seat 4 and moves in the same direction along the slide rail 112 to ensure the stability of the movement of the plug-in floating assembly.

[0037] See Figures 5-12 The pluggable floating assembly includes a mounting plate 8. The mounting plate 8 is bolted to the upper surface of the horizontal plate 7 near the test bench 2. A mounting groove is provided in the middle of the mounting plate 8. The upper and lower ends of the mounting plate 8 are integrally provided with protruding structures. Multiple connecting rods 15 are connected through both sets of protruding structures, with a gap between the connecting rods 15 and the inner surface of the protruding structures. The multiple connecting rods 15 are evenly arranged. A first auxiliary plate 9 is connected to the side of the mounting plate 8 facing the test bench 2 via the connecting rods 15. The connection between the first auxiliary plate 9 and the top of the mounting plate 8 is a snap-fit ​​structure. For example,... Figure 10 As shown, the snap-fit ​​structure includes a snap-fit ​​block 19 and a snap-fit ​​groove 20 that matches its size. The snap-fit ​​block 19 protrudes from the top of the first auxiliary plate 9, and the snap-fit ​​groove 20 is formed in the mounting plate 8 at the position corresponding to the snap-fit ​​block 19. The initial state of the mounting plate 8 and the first auxiliary plate 9 is referenced. Figure 3 That is, the first auxiliary plate 9 and the mounting plate 8 are initially separated by a certain distance, which is required to be set between 2-5mm.

[0038] Furthermore, a second auxiliary plate 10 is fixedly connected to the side of the first auxiliary plate 9 facing the test platform 2. A second mounting groove is opened in the middle of the first auxiliary plate 9 corresponding to the position of the first mounting groove. An adapter plate 12 is arranged in contact between the inside of the first mounting groove and the second mounting groove. The adapter plate 12 is fixedly connected to the first auxiliary plate 9 through the bottom surface of the second mounting groove. The fixed connection method includes, but is not limited to, welding, pin fixing, and thread fixing. A first adapter part and a second adapter part are fixedly connected to both ends of the adapter plate 12, respectively. The second adapter part is set close to the plug-in interface, and correspondingly, the first adapter part is set away from the plug-in interface, and is connected to the flexible flat cable under test.

[0039] Specifically, through the design of the gap area and the retention distance, the first auxiliary plate 9 and the second auxiliary plate 10 can float within a certain spatial range. When the floating components are moved synchronously and the interface is plugged in, if the plugging position deviates below the allowable error value, the adapter plate 12 will make a certain degree of positional floating correction under the floating of the first auxiliary plate 9 and the second auxiliary plate 10 to improve the plugging success rate.

[0040] See Figure 3 The bottom of the mounting plate 8 is fitted with a positioning pin 17, which is used to initially determine the positioning accuracy of the insertion action. The positioning pin 17 is connected to the data processing terminal for transmitting the initial positioning signal. In addition, the data processing terminal is also connected to a display screen, which can be used to display the measured electrical performance test results and the related test data.

[0041] See Figures 6-7 The bottom of the second auxiliary plate 10 is provided with a pressing part 16 and a guiding part 14. The bottom surface of the pressing part 16 abuts against the adapter plate 12. The pressing part 16 and the first auxiliary plate 9 together apply a longitudinal supporting force to the adapter plate 12, that is, longitudinal limiting, to maximize the positional accuracy and insertion stability of the adapter plate 12 during insertion. The guiding part 14 is used for positioning guidance during insertion. Specifically, the guiding part 14 is provided at the bottom front end of the second auxiliary plate 10, that is, on the side close to the insertion interface. The guiding part 14 includes a front end portion 141. The inclined portion 142 and the bottom portion 143 are connected to the pressing portion 16 and form a stepped shape. The horizontal plane of the bottom portion 143 is higher than the horizontal plane of the pressing portion 16. The inclined portion 142 and the front end portion 141 are sequentially opened at the front end of the pressing portion 16. The inclined angle of the inclined portion 142 relative to the horizontal plane is preferably 30°-45°. During processing, the connection between the inclined portion 142 and the bottom portion 143 is chamfered to provide guidance before the interface is inserted and to avoid violent collisions during insertion.

[0042] See Figures 8-12 The connecting rod 15 consists of a front part 151, a tail part 152, and a head 153. In the initial state, the head 153 and the shaft of the front part 151 are both located within the protruding structure of the mounting plate 8. The shaft of the front part 151 and the interior of the protruding structure form the aforementioned gap area. A part of the shaft of the tail part 152 passes through the interior of the first auxiliary plate 9 and also forms the aforementioned gap area with the interior of the first auxiliary plate 9. The other part of the shaft of the tail part 152 is located within the space where the retention distance is located. The head 153 is fixedly connected to the protruding structure.

[0043] A buffer structure is provided between the mounting plate 8 and the first auxiliary plate 9. The buffer structure includes an elastic part 18 fixedly connected to the tail of the rod 152. In the compressed state, the elastic part 18 is located inside the first auxiliary plate 9. A gasket is fixedly connected to the end of the elastic part 18 away from the connecting rod 15. The gasket is in support contact with the inner wall of the second auxiliary plate 10. The diameter of the elastic part 18 is not greater than the diameter of the connecting rod 15.

[0044] Specifically, the rod head 153 is fixedly connected to the mounting plate 8. The output end of the first drive unit 3 drives the plug-in floating assembly to move toward the plug-in interface on the test bench 2 through the transmission assembly 11, connecting seat 4, vertical plate 6, and horizontal plate 7. Specifically, the mounting plate 8 and the first auxiliary plate 9 drive the adapter plate 12 to insert into the plug-in interface in an initial state with a maintained distance. ① If the plugging action is accurately positioned, the data processing end will first receive the plugging signal determined by the positioning pin 17 as indicating that the plugging is in place. Wherein:

[0045] In scenario one, when the second adapter part of the adapter board 12 is fully aligned with the plug-in interface, the first auxiliary board 9 and the second auxiliary board 10 do not need to make adaptive floating adjustments, which is the optimal plug-in state.

[0046] In scenario two, when the second adapter portion of the adapter plate 12 cannot be fully aligned with the plug-in interface but can be floated for correction, the inclined portion 142 contacts the plug-in interface on the test bench 2. Under the guidance of the inclined surface, the second adapter portion is guided to align with the plug-in interface. When the second adapter portion cannot be fully plugged in and is subjected to reverse resistance, under the reverse resistance and / or the micro-collision of the test bench 2 on the lower surface of the second auxiliary plate 10, the first auxiliary plate 9 and the second auxiliary plate 10 reduce the distance between them and float in three-dimensional space under the setting of the elastic portion 18 and the gap area. The adapter plate 12 moves slightly in the opposite direction to the auxiliary plate synchronously. Then, under the elastic recovery of the elastic portion 18, the adapter plate 12 and the second adapter portion are guided to plug into the plug-in interface again, thereby achieving the float correction effect.

[0047] Scenario 3: If multiple floating operations fail to achieve the alignment correction effect, the data processing end will issue an alarm.

[0048] ②If the insertion action is not positioned accurately, the data processing terminal will receive the insertion signal determined by the positioning pin 17 as not being inserted properly, and will directly trigger an alarm.

[0049] See Figure 6 A third detection unit 13 is connected between the adapter plate 12 and the mounting plate 8. The third detection unit 13 is used to detect the triaxial force to determine the floating of the adapter plate 12 during the insertion and removal operation. The third detection unit 13 is preferably a triaxial force sensor. It should be noted that the signal connection terminal of the third detection unit 13 is allowed to move slightly with the adapter plate 12.

[0050] Specifically, the actual pressure data measured by the third detection unit 13 is recorded as Fx, Fy, and Fz, and is displayed on the screen in real time.

[0051] In response to the alarm phenomena in the above three situations, on the one hand, the three-way warning pressure values ​​of the third detection unit 13 are pre-input into the data processing terminal and recorded as Fx0, Fy0, and Fz0 respectively. During the connection process, if any actual pressure data exceeds the corresponding warning pressure value, the data processing terminal will perform an alarm. On the other hand, if the above problems do not occur, the alarm will be determined based on the actual number of floating corrections measured by the third detection unit 13. Specifically, a reasonable number of floating corrections is preset. When the actual number exceeds the reasonable number, the data processing terminal will perform an alarm.

[0052] Therefore, by setting up the above modules, automatic plug-in and unplug testing of batch flexible flat cables is first realized, thereby replacing manual plug-in and unplug operations. Secondly, the set plug-in and unplug floating component can adaptively float and adjust according to the misalignment of plug-in and unplug, so as to ensure the accuracy of plug-in and unplug, and improve the efficiency of plug-in and unplug operations.

[0053] See Figure 4 A limit detection component 5 is provided on one side of the connector 4 to ensure the accuracy and safety of the insertion and removal distance. Specifically, a fixed seat 51 is fixedly connected to the outer wall of one side slide rail 112 by bolts. A distance measuring sensor 52 is fixedly installed on the side of the fixed seat 51 near the upper surface of the first drive part 3. A movable seat 53 is slidably connected to the side of the fixed seat 51 away from the upper surface of the first drive part 3. At least one limiting groove 55 is opened inside the side of the movable seat 53 away from the first drive part 3. The limiting groove 55 is arranged in a ring shape. A limiting rod 56 is provided inside the limiting groove 55. The bottom of the limiting rod 56 is fixedly connected to the fixed seat 51. The movable seat 53 is near the first drive part A ranging moving part 54 is fixedly connected to the upper surface of one side of the 3. A fixing part is fixedly connected between the ranging moving part 54 and the connecting seat 4 to drive the ranging moving part 54 and the moving seat 53 to move synchronously. The ranging sensing part 52 is connected to the data processing terminal for signal monitoring of the moving distance and data feedback of the moving distance. When the moving distance does not meet the setting, an alarm will be directly triggered. It is preset that when the ranging moving part 54 reaches the moving distance, the data processing terminal will also receive the insertion signal determined by the positioning pin 17. If the two results are inconsistent, an alarm will be triggered and manual inspection will be performed to ensure the accuracy of the moving distance and positioning.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features, and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
