Description

DETAILED DESCRIPTION

[0044] The present application will be further described in detail below with reference to the accompanying drawings.

[0045] The embodiment of the present application provides a detection equipment.

[0047] The terms "first", "second", "third", "fourth" and the like in the description and in the claims of the present application and in the above-described drawings mean for distinguishing similar objects, not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so designated can be interchanged, where appropriate, to refer to a similarly differentiated object to an order different from those described here. Furthermore, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or apparatus that comprises a list of steps or units is not necessarily limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to such processes, methods, products, or apparatuses.

[0048] Please refer to Figure 1 The detection device is suitable for pressing detection of the pressing piece. The detection device comprises a workbench 1, a conveying line body 2, a positioning mechanism 3, a detection mechanism 4 and a transfer and shunting mechanism 5. The positioning mechanism 3, the detection mechanism 4 and the transfer and shunting mechanism 5 are arranged on the workbench 1. The conveying line body 2 is used for carrying and conveying a jig. The positioning mechanism 3 and the detection mechanism 4 are arranged in position. The positioning mechanism 3 is used for positioning the jig to be detected, so as to limit the movement of the jig and facilitate the detection of the detection mechanism 4. The detection mechanism 4 is used for pressing detection of the pressing piece and determining whether the jig is qualified. The transfer and shunting mechanism 5 is used for shunting the jig according to the detection result. The specific detection process is as follows. The pressing piece is placed on the conveying line body 2 together with the jig. The jig is carried and conveyed by the conveying line body 2. The jig is transferred to the positioning mechanism 3 and the detection mechanism 4 through the conveying line body 2. First, the jig is positioned by the positioning mechanism 3. Then, the detection mechanism 4 performs pressing detection on the pressing piece on the jig. After the detection is completed, the positioning mechanism 3 is released. The jig continues to be transferred to the transfer and shunting mechanism 5 under the action of the conveying line body 2. According to the detection result of the pressing piece, the transfer and shunting mechanism 5 shunts the jig loaded with the pressing piece. The jig loaded with unqualified pressing pieces is removed.

[0049] Referring to Figure 2 and Figure 3 , the transport line body 2 includes two supports 21 arranged oppositely, a speed-up chain module 22 arranged on the supports 21 to carry the transport fixture, and a plurality of rotary bearings 23 arranged on the supports 21 and rotationally matched with the supports 21 to reduce the friction between the fixture and the supports 21. The speed-up chain module 22 includes a first chain 221, a second chain 222, and a driving motor 223 driving the first chain 221 and the second chain 222. The first chain 221 and the second chain 222 are respectively mounted on the two supports 21. The first chain 221 and the second chain 222 are composed of a plurality of sprockets 224. Two driving gears 225 are arranged on the output shaft of the driving motor 223. The two driving gears 225 are respectively engaged with the sprockets 224 on the first chain 221 and the second chain 222 to realize the operation of the first chain 221 and the second chain 222.

[0050] Referring to Figure 3 , the plurality of rotary bearings 23 are arranged on the end surface of the support 21 facing the fixture. The central axis of the rotary bearing 23 is perpendicular to the workbench 1. The outer circumferential wall of the rotary bearing 23 is in contact with the side wall of the fixture to roll. The 360° rotary bearing 23 reduces the friction between the fixture and the support 21 to reduce the generation of dust, which is suitable for thousands of clean rooms. On the other hand, the rotary bearings 23 on both sides of the fixture guide the running direction of the fixture to avoid the deviation of the running direction of the fixture under the action of the speed-up chain module 22.

[0051] Referring to Figure 1 , further, the transport line body 2 is provided with a first line body and a second line body 24. The first line body is used for transporting qualified products, and the second line body 24 is used for transporting unqualified products. The length direction of the first line body coincides with the length direction of the transport line body 2, and the length direction of the second line body 24 is perpendicular to the length direction of the transport line body 2. In this embodiment, the first line body is one end of the transport line body 2 close to the transfer and shunting mechanism 5. The first line body and the transport line body 2 are the same line body, and the first line body and the transport line body 2 are distinguished by the transfer and shunting mechanism 5 as a boundary. The structure of the second line body 24 is the same as that of the transport line body 2, so it is not described here. It can be understood that the fixture after detection is carried to the transfer and shunting mechanism 5 through the transport line body 2. The transfer and shunting mechanism 5 transfers the unqualified fixture to the second line body 24 according to the detection result of the detection mechanism 4 to facilitate subsequent maintenance. The qualified fixture continues to be transmitted to the first line body through the transport line body 2 to reach the next clamping station.

[0052] Referring to Figure 2 , Figure 4 and Figure 5The positioning mechanism 3 comprises a first positioning assembly 31 and a second positioning assembly 32. The first positioning assembly 31 is used for limiting the jig in the Z-axis direction, and the second positioning assembly 32 is used for limiting the jig in the X-axis direction. In the embodiment, the X-axis direction is the length direction of the transport line body 2, the direction perpendicular to the X-axis in the plane where the workbench 1 is located is the Y-axis direction, and the direction perpendicular to the plane where the workbench 1 is located is the Z-axis direction. By positioning the jig in the X-axis and Z-axis directions, the jig is kept stable, which facilitates the pressing detection operation of the jig by the detection mechanism 4.

[0053] Specifically, the first positioning assembly 31 comprises a first pressing plate 311 and a second pressing plate 312 arranged above and below the jig, a first cylinder driving the first pressing plate 311, and a second cylinder driving the second pressing plate 312. The first cylinder and the second cylinder are fixedly arranged on the workbench 1 through a mounting frame 423. The first pressing plate 311 and the second pressing plate 312 are the same in size and shape, and the orthographic projection of the first pressing plate 311 coincides with that of the second pressing plate 312. The first pressing plate 311 is fixedly connected to the output end of the first cylinder, and moves downward under the driving of the first cylinder to contact and press the jig. The second pressing plate 312 is fixedly connected to the output end of the second cylinder, and moves upward under the driving of the second cylinder to contact and lift the jig. The second cylinder drives the second pressing plate 312 to lift the jig so that the jig is separated from the transport line body 2, and the synchronous movement of the jig and the speed-up chain module 22 is released. Then, the first cylinder drives the first pressing plate 311 to cooperate with the second pressing plate 312 to press the jig, thereby limiting the jig in the Z-axis direction. Conversely, the jig is not limited in the Z-axis direction.

[0054] It can be understood that the second cylinder drives the second pressing plate 312 to lift the jig to a height consistent with the setting height of the detection mechanism 4, which facilitates the pressing detection operation of the detection mechanism 4 on the pressing piece and effectively reduces the failure rate.

[0055] Please refer to Figure 5The second positioning assembly 32 is arranged in the direction in which the jig advances, and the second positioning assembly 32 comprises a baffle 321 and a third cylinder 322. The baffle 321 is arranged at the output end of the third cylinder 322, and the third cylinder 322 is slidingly connected to the inner wall of the support 21. The third cylinder 322 drives the baffle 321 to adjust according to the arrangement position of the first positioning assembly 31. The high end of the third cylinder 322 is lower than or equal to the high end of the double-speed chain module 22. The third cylinder 322 is a rotary cylinder. One end of the baffle 321 is fixedly connected to the output shaft of the third cylinder 322. The end of the baffle 321 is used to resist the jig. The plane in which the movement track of the end of the baffle 321 is located is perpendicular to the length direction of the transport line body 2. The third cylinder 322 drives the baffle 321 to rotate to press against the jig or to avoid the jig. After the first positioning assembly 31 positions the jig, the third cylinder 322 in the second positioning assembly 32 drives the baffle 321 to rotate, so that the end of the baffle 321 contacts and presses against the left end of the jig, and the jig is limited in the advancing direction.

[0056] Please refer to Figure 4 In some other embodiments, the second positioning assembly 32 further comprises a limiting block 323 and a vertical plate 324. The limiting block 323 is rotatably installed at one end of the vertical plate 324 through a rotating shaft, and the other end of the vertical plate 324 is fixedly installed on the workbench 1. The limiting plate is provided with a guide surface. The guide surface is inclined towards the beginning end of the transport line body 2, and the low end of the guide surface is close to the beginning end of the transport line body 2. In the normal state, the high end of the guide surface is higher than the bottom surface of the jig. The jig advances under the action of the double-speed chain module 22. The bottom surface of the jig contacts and presses against the high end of the guide surface. The weight of the jig makes the limiting block 323 and the vertical plate 324 rotate to lower the height of the high end, so as to realize stable advancement of the jig. After the jig passes the limiting plate, the force on the limiting plate is removed, and the high end of the guide surface returns to a state of being higher than the bottom surface of the jig, so as to press against the right end of the jig and limit the jig in the direction opposite to the advancing direction. The baffle 321 and the limiting block 323 cooperate to limit the jig in the X-axis direction.

[0057] In some other embodiments, the left and right ends of the jig can also be provided with third cylinders 322 and baffles 321 respectively, and two groups of oppositely arranged third cylinders 322 and baffles 321 are used to limit the left and right ends of the jig in the X-axis direction.

[0058] Please refer to Figure 6 It should be particularly pointed out that, in the present embodiment, the jig is provided with a mounting groove for mounting a pressing piece. The pressing piece is connected to the jig through a spring. When a pushing force is applied to the pressing piece, the pressing piece can slide relative to the jig. When the pressing piece is pressed to the bottom of the mounting groove, the pressing piece is pressed to the limit. After the pressing piece reaches the limit, the force applied to the pressing piece is removed, and the pressing piece is reset under the rebounding force of the spring.

[0059] Please refer to Figure 6 and Figure 7 , the detection mechanism 4 is located on one side of the transportation line body 2 and is opposite to the positioning mechanism 3, the detection mechanism 4 comprises a sensor 41 and a pressing assembly 42, the sensor 41 and the pressing assembly 42 are both arranged on the transportation line body 2, the pressing assembly 42 and the sensor 41 are arranged opposite to the position of the pressing piece, the sensor 41 is preferably an optical switch, and the sensor 41 is used to detect the moving distance of the pressing piece when the pressing piece is reset, and the pressing assembly 42 is used to contact and press the pressing piece, so that the pressing piece slides to the limit position relative to the jig. When the pressing piece completes a pressing detection and is reset, the moving distance of the pressing piece may change due to resistance or wear, and whether the pressing piece is damaged and whether the jig is qualified can be measured by comparing the actual moving distance of the pressing piece when the pressing piece is reset.

[0060] The pressing assembly 42 comprises a flexible pressing head 421 and a first driving member 422, the first driving member 422 drives the flexible pressing head 421 to move towards or away from the jig, the flexible pressing head 421 moves back and forth along the Y-axis direction, the flexible pressing head 421 is a part that can deform under external force but can still restore to the original state, and the main function of the flexible pressing head 421 is to adapt to the irregular shape of the workpiece surface and provide more conformal contact. The flexible pressing head 421 can not only follow the shape change of the workpiece or the mold, but also can form flexible pressing on the workpiece, so as to avoid damaging the workpiece. The first driving member 422 drives the flexible pressing head 421 to move towards the jig, so that the flexible pressing head 421 contacts and presses the pressing piece, and the pressing piece is pressed to the limit and then resets. The sensor 41 judges whether the pressing piece is damaged according to the moving distance of the pressing piece when the pressing piece is reset.

[0061] It can be understood that the jig slides to the positioning mechanism 3 and the detection mechanism 4 under the action of the transportation line body 2, is positioned by the positioning mechanism 3 so as to be fixed relative to the detection mechanism 4, the first driving member 422 drives the flexible pressing head 421 to move in the direction of the jig, so that the pressing piece is pressed by the flexible pressing head 421 to make the pressing piece slide with the jig, under the driving force of the first driving member 422, the flexible pressing head 421 presses the pressing piece to the limit and then releases the pressing, the pressing piece resets, and whether the pressing piece is damaged is measured according to the reset distance of the pressing piece detected by the sensor 41, and whether the jig is qualified is determined. The flexible pressing head 421 replaces manual pressing by hand, the labor intensity of employees is low, the pressing detection of the pressing piece is performed by the pressing assembly 42, so that the same force is applied to the pressing piece, the pressing position and method are unified, the misjudgment is reduced, and the detection accuracy is improved. The detection method can be applied to point detection of different pressing pieces, and when the scheme is popularized, only the position, the force and the stroke need to be adjusted, so that the production demand can be met, the method is simple and practical, and the utilization rate is high.

[0062] Further, the pressing assembly 42 further comprises a mounting frame 423, a rotating guide rod 424, a spherical guide column 425 and a spherical bearing 426, the mounting frame 423 is fixedly connected to the workbench 1, the rotating guide rod 424 is arranged at the output end of the first driving member 422 and rotationally matches with the mounting frame 423, the flexible pressing head 421 is arranged at the end of the rotating guide rod 424 away from the first driving member 422, the spherical bearing 426 is arranged between the flexible pressing head 421 and the rotating guide rod 424, and the flexible pressing head 421 is freely guided by the spherical bearing 426 and the rotating guide rod 424 to increase flexibility. The first driving member 422 drives the rotating guide rod 424 to move while driving the flexible pressing head 421 to move towards or away from the pressing piece.

[0063] The rotating guide rod 424 is provided with a V-shaped guide groove 4241, one end of the spherical guide column 425 is rotationally connected with the mounting frame 423, and the other end is located in the V-shaped guide groove 4241 and slidingly matches with the rotating guide rod 424. When the rotating guide rod 424 rotates, the one end of the spherical guide column 425 located in the V-shaped guide groove 4241 moves along the path of the V-shaped guide groove 4241, so that the parallelism of the rotating guide rod 424 is more stable when it rotates, so that the flexible pressing head 421 can accurately press the preset point of the pressing piece each time, and the situation of jamming caused by pressing inclination is avoided.
