[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0045] Washers are the common name for spring washers, which are a type of fastener. Lack of washers during product production may result in unstable installation, vibration and noise, reduced electrical performance, potential safety hazards, and reduced service life.

[0046] Currently, after the manual assembly machine of needle-type products on the market cuts the materials, it is necessary to manually check whether the riveted cover plates have washers one by one to prevent the lack of washers from causing unstable installation, vibration and noise, electrical performance degradation, safety hazards and shortened service life. Each production line needs to be equipped with at least one staff member to conduct a full inspection, which seriously wastes labor costs.

[0047] like Figure 1As shown, the utility model proposes a washer detection device, including: a bracket 1, a mounting seat, a sliding seat, a first driving member 2, a spring ejector assembly and a sensing assembly. A mounting seat and a sliding seat are arranged on the bracket 1 in sequence from top to bottom in the vertical direction, and an upper ejector 33 corresponding to the number of washers 9 of the product 8 is arranged on the mounting seat; the sliding seat is slidably connected to the bracket 1, and the sliding seat can be driven by the first driving member 2 to slide along the bracket 1 away from the mounting seat or close to the mounting seat, and a spring ejector assembly is arranged on the sliding seat, and the spring ejector assembly includes an ejector end and a sensing end, and the ejector end can cooperate with the upper ejector 33 to clamp the position of the washer 9 of the product 8; a sensing assembly is arranged on the sliding seat, and the sensing assembly sends a washer signal or a washer-free signal by sensing the position change of the sensing end of the spring ejector assembly.

[0048] like Figure 2 As shown, in a specific embodiment, a mounting seat is arranged on a bracket 1, and upper ejectors 33 corresponding to the number of washers 9 of a corresponding product 8 are arranged on the mounting seat, and the position of the upper ejectors 33 corresponds to the position of the washers 9 of the product 8. A sliding seat is mounted on the bracket 1, and the sliding seat is located below the mounting seat. A first driving member 2 is arranged at the bottom end of the bracket 1, and the first driving member 2 is connected to the sliding seat, so as to drive the sliding seat to slide up and down along the bracket 1 away from the mounting seat or close to the mounting seat. A spring ejector assembly is arranged on the sliding seat, and the number of the spring ejector assemblies is consistent with the number of the upper ejectors 33. The spring ejector assembly includes an ejector end and a sensing end, and the ejector end can cooperate with the upper ejector 33 to clamp the position of the washers 9 of the product 8. The sensing assembly is also mounted on the sliding seat, and the sensing assembly sends a washer signal and a washer-free signal by sensing the position change of the sensing end.

[0049] When the mounting seat and the sliding seat of the washer detection device are away from each other, the sensing end of the spring ejector assembly corresponds to the sensing area of ​​the sensing component, and the sensing component can sense the sensing end of the spring ejector assembly.

[0050] The mounting seat and the sliding seat are driven by the first driving member 2 to reach the same preset position for each inspection, at which time the ejector end of the spring ejector assembly and the upper ejector 33 just clamp the product 8 .

[0051] If the product 8 has no washer 9 at this time, the sensing end of the spring ejector assembly is still within the sensing range of the sensing assembly, and the sensing assembly can sense the position of the sensing end of the spring ejector assembly and send out a signal that there is no washer; if the product 8 has a washer 9 at this time, the positions of the mounting seat and the sliding seat have not changed. Since the washer 9 has thickness, the spring ejector assembly will be pressed down, and the position of the sensing assembly has not changed, so the sensing assembly cannot sense the position of the sensing end of the spring ejector assembly and sends out a signal that there is a washer.

[0052] In a further embodiment, the spring ejector assembly includes: a lower ejector 23 , a connecting block 28 and a sensing sheet 7 .

[0053] The lower ejector pin 23 is an ejector pin end, and the number of the lower ejector pins 23 is the same as the number of the upper ejector pins 33. The top of the lower ejector pin 23 is provided with a clamping block 11 for clamping the washer 9. The bottom end of the lower ejector pin 23 movably passes through the sliding seat. The outer wall of the lower ejector pin 23 between the clamping block 11 and the sliding seat is sleeved with a spring 26, and the spring 26 is limited by the clamping block 11 and the sliding seat; the number of the connecting blocks 28 is the same as the number of the lower ejector pins 23, and the connecting blocks 28 are connected to the bottom end of the lower ejector pin passing through the sliding seat, and one lower ejector pin 23 is correspondingly connected to one connecting block 28; The sensing piece 7 is the sensing end, and the number of sensing pieces 7 is consistent with the number of connecting blocks 28. The sensing pieces 7 are connected to the connecting blocks 28, and one connecting block 28 is connected to one sensing piece 7. When there is a washer 9 on the product 8, the mounting seat and the sliding seat have not changed their arrival positions. Since the washer 9 has thickness, the lower ejector pin 23 is pressed down and moves downward, driving the connecting block 28 and the sensing piece 7 to move downward as well. Therefore, at this time, the sensing piece 7 is offset from the sensing area of ​​the sensing component and is not within the sensing range of the sensing component. The sensing component sends out a signal that there is a washer. After the mounting seat and the sliding seat are away, the product 8 is removed from the washer detection device. Since the lower ejector pin 23 of the spring ejector pin assembly is covered with a spring 26, the lower ejector pin 23 that is pressed down will be restored to its original position by the elastic force of the spring 26.

[0054] In a further embodiment, the sensing component includes: a mounting plate 5 and a proximity sensor 6 .

The number of proximity sensors 6 is consistent with the number of sensing sheets 7, one proximity sensor 6 corresponds to one sensing sheet 7, the sensing end of the proximity sensor 6 horizontally passes through the mounting hole limit of the mounting sheet 5, and its sensing end is aligned with the sensing portion 12 of the sensing sheet 7. When the product 8 does not have a washer 9, the sensing end of the proximity sensor 6 corresponds to the position of the sensing portion 12 of the sensing sheet 7, and the proximity sensor 6 sends a proximity signal of the sensing sheet 7 to indicate that there is no washer 9, otherwise it sends a non-proximity signal of the sensing sheet 7 to indicate that there is a washer 9.

[0068] In the second specific embodiment, the washer detection device proposed in the utility model can detect two washers 9 at the same time. The two washers 9 are divided into two situations. The first situation is two washers 9 on the same product 8, and the second situation is that two products 8 are each provided with a washer 9. Here, the two washers 9 on the same product 8 in the first situation are taken as an example.

[0069] Specifically, a slide rail 4 is vertically mounted on the bracket 1, and a first slider 24 and a second slider 34 are disposed on the slide rail 4, and the second slider 34 is above the first slider 24. A second driving member 3 is disposed on the top of the bracket 1, and a first driving member 2 is disposed on the bottom of the bracket 1, and both the first driving member 2 and the second driving member 3 are cylinders.

[0070] like Figure 5 As shown, the mounting seat includes: a second slider 34 connecting plate 32 and a second positioning plate 31, the back of the second slider 34 connecting plate 32 is fixed to the second slider 34, the front of the second slider 34 is fixed to the second driving member 3 through a second connecting bearing 35, the second positioning plate 31 is plate-shaped and horizontal and vertically connected to the second slider 34 connecting plate 32, and two upper ejectors 33 vertically pass through the second positioning plate 31 and are fixed to the second positioning plate 31, and correspond to the position of the washer 9 of the product 8. When the second driving member 3 is in operation, it can drive the second slider 34 connecting plate 32 and the second positioning plate 31 and the upper ejectors 33 connected to the second slider 34 connecting plate 32 to move up and down along the slide rail 4 at the same time.

[0071] like Figure 5 As shown, the sliding seat is connected to the first slider 24 and is arranged on the slide rail 4 below the mounting seat. The sliding seat includes: a first slider 24 connecting plate 22 and a first positioning plate 21, the front of the first slider 24 connecting plate 22 is connected to the first slider 24, the back of the first slider 24 connecting plate 22 and the first driving member 2 are fixed through a first connecting bearing 25, the first positioning plate 21 is horizontal and vertically connected to the first positioning plate 21 in a rectangular plate shape, and a spring ejector assembly is provided on the first positioning plate 21.

[0072] like Figure 2As shown, the spring ejector assembly includes: a lower ejector 23, a connecting block 28, a guide rod 10 and a sensing sheet 7. The positions of the two lower ejectors 23 are opposite to the positions of the upper ejector 33, so that the lower ejectors 23 cooperate with the upper ejector 33 to clamp the washers 9 of the product 8. A clamping block 11 is provided at the top of each lower ejector 23, and a notch is provided on the clamping block 11 for clamping the washers 9 of the product 8. The bottom end of each lower ejector 23 vertically slides through the first positioning plate 21, and the part of each lower ejector 23 passing through the first positioning plate 21 is respectively connected to a connecting block 28. A spring 26 is sleeved on the outside of the lower ejector 23 between the clamping block 11 and the first positioning plate 21. The spring 26 is a downward pressure spring 26, which is limited by the clamping block 11 of the lower ejector 23 and the first positioning plate 21. Each connecting block 28 corresponds to at least one guide rod 10, and the guide rod 10 movably passes through the first positioning plate 21, and the bottom connecting block 28 is fixed to guide the lower ejector 23 and the connecting block 28. Each connection block 28 is correspondingly installed with a sensing sheet 7, and the sensing sheet 7 includes a connection part and a sensing part 12. The connection part is an inverted L-shaped panel, and the top of the connection part is fixed to the connection block 28. The sensing part 12 in the sensing area of ​​the sensing component is provided on the side of the connection part. The sensing part 12 is two 4mm wide square pieces. The shapes of the connection part and the sensing part 12 are not limited. In order to make the sensing part 12 within the sensing range of the sensing component, the sensing part 12 can be round, square, etc.

[0073] The sensing component includes: a mounting plate 5 and a proximity sensor 6. The mounting plate 5 is L-shaped, and the top end is fixed to the first slider 24 and the connecting plate 22. A bending portion is provided on the side of the mounting plate 5. The bending portion is provided with two mounting holes for fixing the proximity sensor 6. The two sensing ends of the proximity sensor 6 are fixed through the two mounting holes and correspond to the two sensing portions 12 of the sensing plate 7. Each sensing plate 7 corresponds to a proximity sensor 6.

[0074] When the upper ejector pin 33 and the lower ejector pin 23 are in a distanced state, the sensing sheet 7 is within the sensing range of the proximity sensor 6 .

[0075] The first driving member 2 and the second driving member 3 drive the mounting seat and the sliding seat to move to the specified preset position each time according to the thickness of the product 8, so that the upper ejector pin 33 and the lower ejector pin 23 can just clamp the washer 9 of the product 8. If there is no washer 9 on the product 8, the upper ejector pin 33 and the lower ejector pin 23 just clamp the product 8, and the spring 26 of the lower ejector pin 23 does not change and will not be pressed down, so the connection block 28 and the sensing sheet 7 connected thereto remain unchanged in position, and the sensing sheet 7 is still in the sensing area of ​​the proximity sensor 6. At this time, the proximity sensor 6 sends a proximity signal indicating that there is no washer 9. If there is a washer 9 on the product 8, when the mounting seat and the sliding seat move to the specified preset position, due to the thickness of the washer 9, when the position of the mounting seat and the sliding seat does not change and the upper ejector pin 33 cannot move, the lower ejector pin 23 is pressed down, and the spring 26 is compressed at the same time, and the connection block 28 and the sensing sheet 7 connected to the lower ejector pin 23 also move downward, so the sensing sheet 7 will leave the sensing range of the proximity sensor 6, and the proximity sensor 6 sends a no proximity signal indicating that there is a washer 9.

[0076] One upper ejector pin 33 corresponds to one spring ejector pin assembly and one sensing assembly, so it can be determined whether there are washers 9 at two locations of the product 8 respectively.

[0077] There may also be two washers in a product. The last moving positions of the upper ejector and the lower ejector are changed according to the thickness of the washers to determine whether there are two washers.

[0078] In a further embodiment, an upper base 37 is installed at the upper ejector pin 33, and a lower base 27 is installed at the lower ejector pin 23. The upper base 37 and the lower base 27 have the same structure, including a horizontal plate and vertical plates vertically connected to both sides of the horizontal plate. The upper ejector pin 33 passes through the horizontal plate of the upper base 37, and the horizontal plate of the upper base 37 is fixed to the second positioning plate 31; the lower ejector pin 23 passes through the horizontal plate of the lower base 27 and is fixed to the first positioning plate 21, and the vertical plates of the upper base 37 and the vertical plates of the lower base 27 clamp the product 8 placed on the lower ejector pin 23. The washer 9 of the product 8 is placed at the lower ejector pin 23, and the upper ejector pin 33 and the lower ejector pin 23 clamp the washer 9, and the upper base 37 and the lower base 27 clamp and fix the product 8, so as to prevent the product 8 from being too large and only the upper ejector pin 33 and the lower ejector pin 23 from being fixed firmly.

[0079] The present application also proposes an automated device for producing and assembling capacitor components, which includes the washer detection device of the present application for detecting whether there is a capacitor;

[0080] like Figure 3 As shown, the capacitor assembly includes a capacitor core, one end of which is provided with two foil guide strips 13, the two foil guide strips 13 are connected to a capacitor cover plate 14, and a washer is respectively provided at the foil guide strips 13 on the capacitor cover plate 14.

[0081] like Figure 4As shown, the fixture places the capacitor cover plate 14 of the capacitor core where the washer should be installed on the clamping block of the lower ejector for automatic detection. If there is no washer 9, it can be directly removed.

[0082] Specific detection steps:

[0083] The first driving member 2 and the second driving member 3 drive the mounting seat and the sliding seat to move away, and a gap is generated between the upper ejector pin 33 and the lower ejector pin 23. The capacitor assembly is moved from the previous position to the washer detection device through the fixture of the previous step on the assembly line. The washer 9 of the capacitor cover plate 14 is placed on the lower ejector pin 23. If the capacitor cover plate 14 has multiple washers 9, each washer 9 corresponds to a lower ejector pin 23. The first driving member 2 and the second driving member 3 drive the mounting seat and the sliding seat to get closer, and the upper ejector pin 33 and the lower ejector pin 23 cooperate to clamp the capacitor cover plate 14 at the washer 9. If there is a washer 9 on the capacitor cover plate 14, since the washer 9 has thickness, the lower ejector pin 23 is pressed down, and at the same time, the spring 26 is compressed, and the connecting block 28 and the sensing sheet 7 connected to the lower ejector pin 23 also move downward, so the sensing sheet 7 will leave the sensing range of the proximity sensor 6. At this time, the proximity sensor 6 sends a no proximity signal indicating that there is a washer 9, and this capacitor cover plate 14 is qualified. If the capacitor cover 14 has no washer, the induction sheet 7 is still in the sensing area of ​​the proximity sensor 6. At this time, the proximity sensor 6 sends a proximity signal indicating that there is no washer 9, and this unqualified product can be discarded.

[0084] After the test is completed, the automated equipment rotates and moves the next capacitor component to be tested to the washer testing device, and then moves in sequence according to the process to achieve fully automated online testing.

[0085] Compared with the prior art, the utility model is provided with a mounting seat and a sliding seat on the bracket 1, an upper ejector 33 is provided on the mounting seat, a lower ejector 23 corresponding to the upper ejector 33 for clamping the product 8 is provided on the sliding seat, a spring 26 is provided on the outer sleeve of the lower ejector 23, a connecting block 28 is provided at the bottom of the ejector, and a sensing sheet 7 is provided on the connecting block 28; a proximity sensor 6 is provided on the sliding seat, when there is no washer 9 on the product 8, the sensing sheet 7 is within the sensing range of the proximity sensor 6 after the upper ejector 33 and the lower ejector 23 are clamped, and the proximity sensor 6 sends a signal that there is no washer, and when there is a washer 9 on the product 8, the upper ejector 33 and the lower ejector 23 are clamped, and the lower ejector 23 drives the sensing sheet 7 to move downward, and the sensing sheet 7 is not within the sensing range of the proximity sensor 6, and the proximity sensor 6 sends a signal that there is a washer. This solves the problem that specific personnel need to be arranged on the production line to detect whether there is a washer 9, which wastes human resources.
