DETAILED DESCRIPTION

[0021] Embodiment 1: See also Figures 1 to 4 The embodiment of the present invention provides an automatic 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 is disposed an adsorption and conveying module 2 for adsorbing the workpiece and driving it to move. The frame 1 is also provided with a CCD detection module 3 located directly above the adsorption and conveying module 2.

[0022] Among them, the adsorption and conveying module 2 has multiple independent air paths, which can form negative pressure or normal pressure, and then adsorb or stop adsorbing the workpiece; and the CCD detection module 3 adopts camera irradiation detection, which and the adsorption and conveying module 2 are existing mature technologies and will not be described in detail here.

[0023] Furthermore, the frame 1 is provided with a support assembly 4 located directly below the adsorption and conveying module 2. The support assembly 4 is used to place a number of workpieces stacked from top to bottom, and the support assembly 4 is in an active fit with the adsorption and conveying module 2. The frame 1 is provided with a control assembly 5 for driving a number of workpieces to move in the up and down directions. When the control assembly 5 rises, it can drive a number of workpieces to rise, so that the workpieces are attached to the adsorption and conveying module 2 and the adsorption is completed by the adsorption and conveying module 2. Then the control assembly 5 descends and drives the workpieces to descend synchronously. At this time, the top workpiece is adsorbed and will not descend. When the control assembly 5 continues to descend, it can push the support assembly 4 to descend as well, so that the support assembly 4 and the adsorption and conveying module 2 are switched from an active fit state to a separation state, and then the adsorption and conveying module 2 can start to drive the workpieces to rotate.

[0024] 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 as a whole, which has a better adsorption effect on the workpiece and is conducive to ensuring the detection accuracy of the CCD detection module 3 directly above.

[0025] Reference Figure 1 and Figure 2In this embodiment, preferably: the support assembly 4 includes a shell 401 that is slidably matched with the frame 1, and a cavity is formed inside the shell 401 for placing the workpiece from top to bottom. A first spring 402 is fixedly installed between the bottom of the shell 401 and the bottom surface of the frame 1. Under the action of the first spring 402, the shell 401 has an upward trend, and then maintains a movable fit state with the adsorption and conveying module 2. In order to reduce the friction loss of the top surface of the shell 401 and the adsorption and conveying module 2, a plurality of balls 404 are movably installed on the top surface of the shell 401, and the balls 404 are fitted with the adsorption and conveying module 2.

[0026] Furthermore, edges 403 are fixedly installed on both sides of the bottom surface of the shell 401, and a gap is formed between the two edges 403 for the control component 5 to pass through; when the control component 5 rises, the edges 403 will not interfere, and when the control component 5 continues to descend, it can contact the edges 403 and drive the shell 401 to descend through the edges 403; at the same time, the two edges 403 prevent the workpiece in the shell 401 from automatically falling out of the shell 401.

[0027] Reference Figures 1 to 3 In this embodiment, preferably: the control component 5 includes a cylinder 501 fixedly mounted on the bottom surface of the frame 1, and the output shaft of the cylinder 501 is fixedly mounted with a push plate 502 extending into the shell 401. The output shaft of the cylinder 501 passes between the 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 up and down directions and prevent the workpiece from falling from the push plate 502.

[0028] When in use, several workpieces are stacked from top to bottom in the shell 401 and supported by the push plate 502, and then the cylinder 501 is started to drive several workpieces to rise, so that the top workpiece is in contact with the outer surface of the adsorption and conveying module 2, and then the adsorption and conveying module 2 is started to complete the adsorption of the top workpiece; then the cylinder 501 descends and drives several workpieces to descend through the push plate 502, leaving only the top workpiece adsorbed on the adsorption and 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 drives the shell 401 to descend through the edge 403 while squeezing the first spring 402, after the shell 401 descends, the ball 404 is separated from the adsorption and conveying module 2, and at this time the adsorption and conveying module 2 can rotate and drive the workpiece to move, and when it moves to the top, the CCD detection module 3 performs size detection, and after the detection is completed, the adsorption and conveying module 2 drives the workpiece to continue rotating.

[0029] It should be noted that: when the workpiece directly below is rising for adsorption, there is also a workpiece directly above for size detection. At this 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 circuits set by the adsorption and conveying module 2.

[0030] Further, see Figure 4 In this embodiment, a material box 6 for receiving workpieces is provided on the frame 1. Two material boxes 6 may be provided, one of which is used to place qualified workpieces, and the other is used to place unqualified workpieces, and 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 to be qualified, it is released from the material box 6 corresponding to the qualified one, and if it is detected to be unqualified, it is released from the material box 6 corresponding to the unqualified one.

[0031] In the above structure, the length dimension of the material box 6 along the axial direction of the adsorption and conveying module 2 may be smaller than the length dimension of the shell 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 extending out of the material box 6, thereby facilitating the one-time collection of subsequent staff, and further improving the overall work efficiency.

[0032] In summary, through the cooperation of the structures such as the housing 401, the push plate 502, the edge 403 and the first spring 402, the workpieces stacked from top to bottom can be adsorbed in sequence with the adsorption conveying module 2, which can effectively improve the loading speed of the workpieces and relatively improve the overall detection efficiency. At the same time, after the detection is completed, the workpieces can also be stacked from top to bottom in the material box 6, which is convenient for the subsequent staff to quickly pick up the workpieces, and can also effectively improve the work efficiency and reduce the overall burden.

[0033] In the present application, the workpiece can be adsorbed in a flush state, which can ensure the adsorption quality of the workpiece by the adsorption and conveying module 2, is not limited by the size of the roller and the position of the air path, and can ensure the detection accuracy of the subsequent CCD detection module 3. At the same time, the entire adsorption state also facilitates the subsequent drop of the workpiece into the material box 6, avoiding the situation where part of the workpiece falls outside the material box 6, and the overall practicality is higher.

[0034] Embodiment 2: See also Figures 1 to 8 Based on the first embodiment, considering that the length of the push plate 502 is greater than the length of the workpiece, the workpiece may have a front-to-back deviation on the push plate 502, which may affect the adsorption effect of the workpiece and the adsorption and conveying module 2 after the push plate 502 rises.

[0035] To this end, the housing 401 is improved: a moving assembly 8 that can slide forward and backward is provided on the housing 401, and a wedge block 7 corresponding to the position of the moving assembly 8 is provided on the frame 1. When the push plate 502 descends and contacts the edge 403, the housing 401 and the moving assembly 8 can be driven to descend synchronously through the edge 403, so that the moving assembly 8 contacts the wedge block 7 and moves back and forth, and in this process, the workpiece can be positioned by shaking forward and backward.

[0036] Reference Figure 5 and Figure 8 In this embodiment, preferably: the moving component 8 includes two partitions 801 arranged front and 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 shell 401, and the surface of the connecting rod 803 is flush with the inner wall of the shell 401, so that the setting of the connecting rod 803 will not affect the up and down movement of the workpiece in the shell 401.

[0037] Furthermore, a second spring 804 is fixedly installed between the rear surface of the rear partition 801 and the inner rear wall of the shell 401. The second spring 804 makes the rear partition 801 have a tendency to move forward, but the front partition 801 does not extend from the front of the shell 401, so that in the initial state, the front partition 801 can be flush with the front surface of the shell 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 forward and backward.

[0038] Reference Figure 6 In this embodiment, a plurality of arc-shaped protrusions are provided on the surface of the wedge block 7 close to the shell 401. When the push rod 802 descends, it can contact with the plurality of arc-shaped protrusions in sequence, thereby making the push rod 802 and the two partitions 801 move forward and backward.

[0039] It can be understood 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 801, so that the forward and backward movement of the partition 801 can have a shaking effect on all workpieces on the push plate 502.

[0040] When in use, the workpieces stacked from top to bottom can be adsorbed to the adsorption conveying module 2 in sequence through the structures such as the shell 401, the push plate 502 and the edge 403, and the workpieces can be adsorbed in a flush state. The working process and effect of this part are the same as those in the first embodiment, 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 shell 401 and the partition 801 to descend synchronously. When the push rod 802 contacts the wedge block 7 and the protrusion, the push rod 802 can be moved forward and backward through the second spring 804, and then the two partitions 801 are also moved forward and backward through the connecting rod 803, so that all the workpieces on the push plate 502 can be shaken back and forth.

[0041] Compared with the first embodiment, through the cooperation of the structures such as the housing 401, the partition 801, the push rod 802 and the wedge block 7, when the push plate 502 drives the housing 401 to descend, the two partitions 801 can be moved forward and backward synchronously, and all the workpieces on the push plate 502 can be shaken forward and backward, so that the workpieces on the push plate 502 can form a good correspondence with the adsorption and conveying module 2, thereby ensuring the adsorption effect of subsequent workpieces. The overall solution is combined with the movement of the housing 401 to achieve effective positioning of the work along the front and back directions, so that the positions of subsequent workpieces falling into the material box 6 are also roughly the same, which can also facilitate the subsequent staff to quickly take out the workpieces from the material box 6, and the applicability is stronger.

[0042] Embodiment three: See also Figures 1 to 10 On the basis of the second embodiment, considering that the width dimension of some workpieces is smaller than the spacing dimension in the shell 401, that is, smaller than the left and right width dimension of the push plate 502, the workpieces may have left and right deviations 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.

[0043] To this end, the housing 401 is further improved: side plates 9 are slidably installed on both sides of the inner wall of the housing 401, and a third spring 10 is fixedly installed between the surface of the side plate 9 and the housing 401. The third spring 10 makes the surface of the side plate 9 flush with the inner wall of the housing 401, so that the setting of the side plate 9 will not affect the up and down conveyance of the workpiece. The side plate 9 slides left and right based on the housing 401, and when the two side plates 9 are relatively close, the workpiece can be shaken and positioned in the left and right directions.

[0044] Reference Fig. 9 and Fig.10In this embodiment, preferably: the connecting rod 803 includes a long rod 8031 ​​that slides forward and backward with the housing 401, and the two ends of the long rod 8031 ​​are fixedly connected to the two partitions 801 respectively; the surface of the long rod 8031 ​​near the edge 403 is provided with a groove 8033 for the side plate 9 and the third spring 10 to be placed, and the groove 8033 is designed in an L shape as a whole, so that the third spring 10 can be connected to the housing 401. The position of the long rod 8031 ​​corresponding to the groove 8033 is provided with a slope 8032 corresponding to the position of the side plate 9. When the long rod 8031 ​​moves forward and backward with the partition 801, the slope 8032 can push the side plate 9 to slide out of the housing 401 and pull the third spring 10.

[0045] 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 workpieces on the push plate 502 .

[0046] When in use, through the structures such as the shell 401, the push plate 502 and the edge 403, the workpieces stacked from top to bottom can be adsorbed to the adsorption conveying module 2 in sequence, and the workpieces can be adsorbed in a flush state; through the structures such as the shell 401, the partition 801 and the wedge block 7, all the workpieces on the push plate 502 can be shaken back and forth. The working process and effect of this part are the same as those in the second embodiment, and will not be repeated here. The difference is: when the front partition 801 moves back and forth through the top rod 802 and the 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 the shell 401 through the slope 8032 and the third spring 10, so that the two side plates 9 form a process of relative approach and distance, thereby realizing the left and right shaking positioning of all the workpieces on the push plate 502.

[0047] Compared with the second embodiment, through the coordination of the partition 801, the long rod 8031, the side plate 9 and the third spring 10, when the partition 801 shakes back and forth, the long rod 8031 ​​can be driven to move synchronously, and the long rod 8031 ​​is used to make the side plate 9 form a reciprocating left and right sliding process based on the shell 401, thereby realizing the left and right shaking positioning of all workpieces on the push plate 502, so that the workpiece and the adsorption and conveying module 2 form a vertical positive correspondence (corresponding to its center), which can further ensure the adsorption effect of the adsorption and conveying module 2 on the workpiece. The overall solution is combined with the movement of the partition 801, so that the workpiece can be adsorbed at the center of the adsorption and conveying module 2, and when the workpiece is rotated to the top, it can also form a vertical positive correspondence with the CCD detection module 3, thereby ensuring the detection effect of the CCD detection module 3 on the workpiece, meeting more requirements in actual use.
