Description

Technical Field

[0001] This invention relates to the field of ribbon cable production technology, and in particular to an automated dimensional inspection device for FFC ribbon cable production. Background Technology

[0002] FFC (Flexible Fabric Charge) cables are a new type of data cable made by pressing together PET insulation material and extremely thin tin-plated flat copper wire using automated equipment. They offer advantages such as flexibility, easy bending and folding, and small size. During production, dimensional inspection is required. Current technology often uses a feeding mechanism to feed the cable, combined with a CCD detection module for automatic image inspection.

[0003] For example, Chinese Patent Publication No. CN105416977A discloses a vacuum roller-type feeding mechanism and an automatic FFC size detection machine using the same. The mechanism includes a frame, a feeding device, a conveying device, an air circuit assembly, and a control system. The feeding device and conveying device are mounted on the frame, and flexible soft material is conveyed from the feeding device to the conveying device. The conveying device includes a roller and a driver; the roller is driven by the driver, and its surface has several groups of air holes. The air circuit assembly includes a vacuum pump and several independent air circuits, one end of which is connected to the vacuum pump, and the other end is connected to the air hole groups. The air hole groups adsorb the flexible soft material, thus driving its conveying. The control system is electrically connected to both the conveying device and the air circuit assembly, and controls both components. By utilizing air pressure difference to adsorb and convey the flexible soft material, the feeding mechanism avoids problems such as material leakage, material carrying, and inaccurate feeding, thereby improving the accuracy of the feeding mechanism.

[0004] The workpiece in this application is attached to the conveyor device from right to left along the conveyor belt. At this time, the two ends of the workpiece may not be able to form an effective correspondence with the air hole group of the conveyor device, which makes it impossible for the two ends of the workpiece to form an effective fit with the roller. As a result, the workpiece cannot be guaranteed to move vertically on the roller, which affects the overall detection effect of the CCD inspection machine on the workpiece and has certain limitations in use.

[0005] Therefore, it is necessary to provide an automated dimensional inspection device for FFC cable production to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an automated dimensional inspection device for FFC cable production, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, an automated dimension inspection device for FFC (Flat Cable Fabrication) production is designed, which allows the workpiece to be flush and adsorbed as a whole, and the workpiece can be automatically and quickly fed.

[0008] Based on the above ideas, the present invention provides the following technical solution: an automated size inspection device for FFC cable production, comprising a frame, an adsorption and conveying module for adsorbing workpieces and a CCD detection module for inspecting workpieces, a support component for placing workpieces on the frame, the support component being located directly below the adsorption and conveying module and movably attached to it, and a control component for driving the workpieces to move up and down on the frame; activating the control component can drive the workpieces to rise, so that the uppermost workpiece is adsorbed by the adsorption and conveying module; when the control component drives the workpieces to fall, it can drive the support component to fall, so that the support component separates from the adsorption and conveying module.

[0009] As a further aspect of the present invention: the support assembly includes a housing that slides with the frame, a first spring is fixedly installed between the bottom of the housing and the frame, a plurality of balls are movably installed on the top surface of the housing, and edges are fixedly installed on both sides of the bottom surface of the housing, with a gap formed between the two edges to allow the control assembly to pass through.

[0010] As a further aspect of the present invention: the housing slides up and down based on the frame, and the first spring causes the housing to have an upward tendency, thereby causing the ball bearings to be in a movable and close fit with the adsorption and conveying module.

[0011] As a further aspect of the present invention: when the control component rises, it can push the workpiece to rise; when the control component falls, it can drive the workpiece to fall and, through the edge, it can drive the housing to fall synchronously.

[0012] As a further aspect of the present invention: the control component includes a cylinder fixedly mounted to the frame, the output shaft of the cylinder being fixedly mounted with a push plate extending into the housing, the output shaft of the cylinder passing between two edges, and the size of the push plate being adapted to the size of the inner wall of the housing.

[0013] As a further embodiment of the present invention: a movable component is slidably disposed on the housing, and a wedge block corresponding to the position of the movable component is disposed on the frame; when the push plate descends and contacts the edge, the housing and the movable component can be driven to descend synchronously through the edge; when the movable component contacts the wedge block, it can move back and forth based on the housing.

[0014] As a further aspect of the present invention: the moving component includes two partitions arranged front to back, the two partitions being fixedly connected by a connecting rod, the connecting rod being slidably embedded in the inner wall of the housing, and the surface of the connecting rod being flush with the inner wall of the housing, and a second spring being fixedly installed between the rear surface of the rear partition and the inner rear wall of the housing.

[0015] As a further aspect of the present invention: the surface of the wedge block is provided with a plurality of protrusions, all of which are arc-shaped and arranged vertically; when the push rod descends and contacts the plurality of protrusions, the push rod can slide back and forth based on the housing.

[0016] As a further aspect of the present invention: the length direction of the workpiece is parallel to the axial direction of the adsorption and conveying module, so that the workpiece can be adsorbed onto the adsorption and conveying module in a flush state.

[0017] As a further aspect of the present invention: the frame is provided with two material boxes for receiving workpieces, one for placing qualified workpieces and the other for placing unqualified workpieces, and the length of the material box along the axial direction of the adsorption and conveying module is smaller than the length of the housing along the axial direction of the adsorption and conveying module.

[0018] Compared with existing technologies, the advantages of this invention are: through the cooperation of the frame, support components, and control components, workpieces stacked from top to bottom can be sequentially adsorbed by the adsorption and conveying module, which can effectively improve the workpiece loading speed and relatively improve the overall detection efficiency. Furthermore, the workpieces can be adsorbed in a flush position, ensuring the adsorption quality of the workpieces by the adsorption and conveying module, thereby ensuring the detection accuracy of the subsequent CCD detection module, resulting in higher overall practicality.

[0031] Example 1:

[0032] Please see Figures 1 to 4 This invention provides an automated size detection device for FFC cable production, which is mainly used to realize rapid loading of workpieces and improve overall work efficiency. The device includes a frame 1, on which an adsorption conveying module 2 for adsorbing and moving workpieces is provided, and a CCD detection module 3 located directly above the adsorption conveying module 2 is also provided on the frame 1.

[0033] The adsorption and conveying module 2 has multiple independent air paths, which can form negative pressure or normal pressure to adsorb or stop adsorption of the workpiece; while the CCD detection module 3 adopts camera illumination detection, which, like the adsorption and conveying module 2, is an existing mature technology and will not be described in detail here.

[0034] Furthermore, a support component 4 is provided on the frame 1, located directly below the adsorption conveying module 2. The support component 4 is used to place several workpieces stacked from top to bottom, and the support component 4 is in a movable contact with the adsorption conveying module 2. A control component 5 is provided on the frame 1 to drive the several workpieces to move in the vertical direction. When the control component 5 rises, it can drive the several workpieces to rise, so that the workpieces are in contact with the adsorption conveying module 2 and are adsorbed by the adsorption conveying module 2. Then, the control component 5 descends and drives the workpieces to descend synchronously. At this time, the uppermost workpiece is adsorbed and will not descend. When the control component 5 continues to descend, it can push the support component 4 to descend as well, so that the support component 4 and the adsorption conveying module 2 switch from a movable contact state to a separated state. Then, the adsorption conveying module 2 can be started to drive the workpieces to rotate.

[0035] In the above structure, the length direction of the workpiece is parallel to the axial direction of the adsorption and conveying module 2, so that the workpiece can be adsorbed on the adsorption and conveying module 2 in a flush state. This results in a better adsorption effect on the workpiece and helps to ensure the detection accuracy of the CCD detection module 3 directly above.

[0036] Reference Figure 1 and Figure 2 In this embodiment, preferably, the support assembly 4 includes a housing 401 that slides vertically with the frame 1. The housing 401 has an internal cavity for placing workpieces from top to bottom. A first spring 402 is fixedly installed between the bottom of the housing 401 and the bottom surface of the frame 1. Under the action of the first spring 402, the housing 401 tends to rise, thus maintaining a movable contact with the adsorption and conveying module 2. To reduce frictional wear between the top surface of the housing 401 and the adsorption and conveying module 2, several ball bearings 404 are movably installed on the top surface of the housing 401, forming a contact with the adsorption and conveying module 2.

[0037] Furthermore, two edges 403 are fixedly installed on both sides of the bottom surface of the housing 401, and a gap is formed between the two edges 403 to allow the control component 5 to pass through. When the control component 5 rises, the edges 403 will not interfere. When the control component 5 continues to descend, it can contact the edges 403 and drive the housing 401 to descend through the edges 403. At the same time, the two edges 403 prevent the workpiece inside the housing 401 from falling out of the housing 401 automatically.

[0038] Reference Figures 1 to 3 In this embodiment, preferably, the control component 5 includes a cylinder 501 fixedly installed on the bottom surface of the frame 1. The output shaft of the cylinder 501 is fixedly installed with a push plate 502 extending into the housing 401. The output shaft of the cylinder 501 passes between two edges 403, and the size of the push plate 502 is adapted to the size of the cavity, which can realize the pushing of the workpiece in the vertical direction and prevent the workpiece from falling off the push plate 502.

[0039] In use, several workpieces are stacked from top to bottom inside the housing 401 and supported by the push plate 502. Then, the cylinder 501 is activated to lift several workpieces, so that the topmost workpiece is in contact with the outer surface of the adsorption conveying module 2. Then, the adsorption conveying module 2 is activated to adsorb the topmost workpiece. Next, the cylinder 501 descends, and the push plate 502 drives several workpieces to descend, leaving only the topmost workpiece adsorbed on the adsorption conveying module 2. At this time, the cylinder 501 drives the push plate 502 to continue to descend, so that the bottom surface of the push plate 502 contacts the top surface of the edge 403, and the edge 403 drives the housing 401 to descend while squeezing the first spring 402. After the housing 401 descends, the ball bearing 404 separates from the adsorption conveying module 2. At this time, the adsorption conveying module 2 can rotate and drive the workpiece to move. When it moves to the top, the CCD detection module 3 performs size detection. After the detection is completed, the adsorption conveying module 2 drives the workpiece to continue to rotate.

[0040] It should be noted that when a workpiece is being lifted and adsorbed from below, a workpiece is also being inspected for size from above. At the same time, there is also an adsorbed workpiece on the lower side of the adsorption and conveying module 2. The above process can be achieved through multiple independent air paths set in the adsorption and conveying module 2.

[0041] Furthermore, refer to Figure 4 In this embodiment, the frame 1 is provided with a material box 6 for receiving workpieces. Two material boxes 6 can be provided, one for placing qualified workpieces and the other for placing unqualified workpieces. Both material boxes 6 correspond to the lower side of the adsorption and conveying module 2. After the workpiece is detected by the CCD detection module 3, it can continue to rotate with the adsorption and conveying module 2. When it rotates to the lower side of the adsorption and conveying module 2, if it is detected as qualified, the adsorption is released at the corresponding material box 6; if it is detected as unqualified, the adsorption is released at the corresponding material box 6.

[0042] In the above structure, the length of the material box 6 along the axial direction of the adsorption and conveying module 2 can be smaller than the length of the housing 401 along the axial direction of the adsorption and conveying module 2, so that after the workpiece falls into the material box 6, its front end is in a state of partially protruding from the material box 6, which facilitates the subsequent one-time picking up of the workpiece by the staff and can further improve the overall work efficiency.

[0043] In summary, through the cooperation of the housing 401, push plate 502, edge 403, and first spring 402, workpieces stacked from top to bottom can be sequentially adsorbed by the adsorption and conveying module 2, effectively improving the workpiece loading speed and overall inspection efficiency. Simultaneously, after inspection, the workpieces can be stacked from top to bottom in the material box 6, facilitating quick retrieval by subsequent staff, further improving work efficiency and reducing overall workload.

[0044] In this application, the workpiece can be fully adsorbed in a flush state, which can ensure the adsorption quality of the workpiece by the adsorption and conveying module 2. It is not limited by the size of the roller or the position of the air path, which can ensure the detection accuracy of the subsequent CCD detection module 3. At the same time, the overall adsorption state also facilitates the subsequent dropping of the workpiece into the material box 6, avoiding the situation where part of the workpiece falls outside the material box 6, thus improving its overall practicality.

[0045] Example 2:

[0046] Please see Figures 1 to 8 Based on Embodiment 1, considering that the length of the pusher plate 502 is greater than the length of the workpiece, the workpiece may have front-to-back deviation on the pusher plate 502, which may affect the adsorption effect between the workpiece and the adsorption conveying module 2 after the pusher plate 502 rises.

[0047] Therefore, the housing 401 is improved: a movable component 8 that can slide back and forth is provided on the housing 401, and a wedge block 7 corresponding to the position of the movable component 8 is provided on the frame 1. When the push plate 502 descends and contacts the edge 403, the edge 403 can drive the housing 401 and the movable component 8 to descend synchronously, so that the movable component 8 contacts the wedge block 7 and realizes back-and-forth reciprocating movement. During this process, the workpiece can be positioned by back-and-forth swaying.

[0048] Reference Figure 5 and Figure 8 In this embodiment, preferably, the moving component 8 includes two partitions 801 arranged front to back, the two partitions 801 are fixedly connected by a connecting rod 803, and the connecting rod 803 is slidably embedded in the inner wall of the housing 401, the surface of the connecting rod 803 is flush with the inner wall of the housing 401, so that the arrangement of the connecting rod 803 will not affect the up and down movement of the workpiece in the housing 401.

[0049] Furthermore, a second spring 804 is fixedly installed between the rear surface of the rear partition 801 and the inner rear wall of the housing 401. The second spring 804 causes the rear partition 801 to tend to move forward, but the front partition 801 will not extend from the front of the housing 401, so that in the initial state, the front partition 801 can be flush with the front surface of the housing 401. A push rod 802 corresponding to the position of the wedge block 7 is fixedly installed on the front surface of the front partition 801. When the push rod 802 descends, it can contact the wedge block 7 and move back and forth.

[0050] Reference Figure 6 In this embodiment, the surface of the wedge block 7 near the housing 401 is provided with several arc-shaped protrusions. When the push rod 802 descends, it can contact the several arc-shaped protrusions in sequence, thereby causing the push rod 802 and the two partitions 801 to move back and forth.

[0051] It is understandable that when the push plate 502 descends and contacts the top surface of the edge 403, the top surface of the push plate 502 is flush with the bottom surface of the partition plate 801, so that the back-and-forth movement of the partition plate 801 can have a shaking effect on all the workpieces on the push plate 502.

[0052] In use, the structure including the housing 401, push plate 502, and edge 403 allows workpieces stacked from top to bottom to be sequentially adsorbed by the adsorption and conveying module 2, and the workpieces can be adsorbed in a flush state. The working process and effect of this part are the same as in Example 1, and will not be repeated here. The difference is that after the cylinder 501 drives the push plate 502 to continue to descend and the push plate 502 contacts the edge 403, the descent of the push plate 502 can drive the housing 401 and the partition plate 801 to descend synchronously. When the top rod 802 contacts the wedge block 7 and the protrusion, the second spring 804 can make the top rod 802 move back and forth, and then the connecting rod 803 can make the two partition plates 801 move back and forth, thereby making all the workpieces on the push plate 502 swing back and forth.

[0053] Compared to Embodiment 1, through the cooperation of structures such as the housing 401, partition 801, push rod 802, and wedge block 7, when the push plate 502 drives the housing 401 to descend, the two partitions 801 can move back and forth synchronously, causing all workpieces on the push plate 502 to sway back and forth. This ensures that the workpieces on the push plate 502 correspond well with the adsorption and conveying module 2, thereby guaranteeing the adsorption effect of subsequent workpieces. The overall solution, combined with the movement of the housing 401, achieves effective positioning along the front-to-back direction, ensuring that subsequent workpieces fall into the material box 6 at roughly the same position. This also facilitates quick retrieval of parts from the material box 6 by subsequent workers, making it more versatile.

[0054] Example 3:

[0055] Please see Figures 1 to 10 Based on Embodiment 2, considering that the width of some workpieces is smaller than the spacing within the housing 401, that is, smaller than the left and right width of the push plate 502, the workpieces may still deviate left and right after being stacked on the push plate 502 from top to bottom, which may also affect the adsorption effect of the workpieces on the adsorption and conveying module 2.

[0056] To address this, the housing 401 is further improved: Side plates 9 are slidably mounted on both sides of the inner wall of the housing 401. A third spring 10 is fixedly installed between the surface of the side plate 9 and the housing 401. The third spring 10 ensures that the surface of the side plate 9 is flush with the inner wall of the housing 401, thus preventing the side plates 9 from affecting the vertical transport of the workpiece. The side plates 9 slide left and right relative to the housing 401. When the two side plates 9 are close to each other, the workpiece can be positioned by swaying in the left and right direction.

[0057] Reference Figure 9 and Figure 10In this embodiment, preferably, the connecting rod 803 includes a long rod 8031 ​​that slides back and forth with the housing 401. Both ends of the long rod 8031 ​​are fixedly connected to two partitions 801 respectively. A groove 8033 is formed on the surface of the long rod 8031 ​​near the edge 403 for accommodating the side plate 9 and the third spring 10. The groove 8033 is L-shaped, allowing the third spring 10 to connect with the housing 401. A slope 8032 corresponding to the position of the side plate 9 is provided on the long rod 8031 ​​at the position of the groove 8033. When the long rod 8031 ​​moves back and forth with the partitions 801, the slope 8032 pushes the side plate 9 out of the housing 401 and pulls the third spring 10.

[0058] When the push plate 502 descends and contacts the top surface of the edge 403, the bottom surface of the side plate 9 is also flush with the top surface of the push plate 502, so that the left and right sliding of the side plate 9 can also act on all the workpieces on the push plate 502.

[0059] In use, the structure of housing 401, push plate 502, and edge 403 allows workpieces stacked from top to bottom to be sequentially adsorbed by the adsorption and conveying module 2, and the workpieces can be adsorbed in a flush state. The structure of housing 401, partition 801, and wedge block 7 allows all workpieces on push plate 502 to be swayed back and forth. The working process and effect of this part are the same as in embodiment 2, and will not be repeated here. The difference is that when the front partition 801 moves back and forth through the top rod 802 and wedge block 7, the front partition 801 drives the long rod 8031 ​​and the rear partition 801 to move back and forth synchronously. When the long rod 8031 ​​moves back and forth, it can drive the side plate 9 to slide left and right based on housing 401 through slope 8032 and third spring 10, so that the two side plates 9 form a process of relatively approaching and moving away, thereby realizing the left and right swaying positioning of all workpieces on push plate 502.

[0060] Compared to Embodiment 2, the combination of the partition 801, long rod 8031, side plate 9, and third spring 10 allows the long rod 8031 ​​to move synchronously when the partition 801 sways back and forth. The long rod 8031 ​​then causes the side plate 9 to slide back and forth on the housing 401, thus enabling the left-right swaying positioning of all workpieces on the push plate 502. This ensures that the workpieces are vertically aligned with the adsorption and conveying module 2 (corresponding to its center), further guaranteeing the adsorption effect of the adsorption and conveying module 2 on the workpieces. The overall solution, combined with the movement of the partition 801, ensures that the workpieces are adsorbed at the exact center of the adsorption and conveying module 2. When the workpiece rotates to the top, it also aligns vertically with the CCD detection module 3, further ensuring the detection effect of the CCD detection module 3 on the workpieces and meeting more practical needs.
