Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of machinery for assembling a plurality of different components into combined unit, and specifically relates to a valve plate assembly detection equipment. BACKGROUND

[0002] The assembly process of restoring valve and bottom valve is basically that valve plate, valve body and other parts are sequentially sleeved on rod to make pre-assembled part, and then the pre-assembled part is fastened according to requirements, wherein the restoring valve is usually fastened on piston rod with nut, and the bottom valve is usually fastened with bolt or riveted with rivet.

[0003] During the assembly of restoring valve and bottom valve, if the number of valve plate is inaccurate, it will seriously affect the performance of valve. In the prior art, the restoring valve or bottom valve assembly equipment usually judges whether the number of valve plate is accurate by detecting the thickness of pre-assembled part, i.e. after the assembly of valve plate is completed, the overall thickness of pre-assembled part is measured, and if the measured value does not exceed the threshold value, it is considered that the number of valve plate is accurate. However, in actual work, the size tolerance of valve body often causes misjudgment.

[0004] Chinese patent document CN 212286620 U discloses an automatic bottom valve piece counting machine, wherein the valve plate picking assembly includes valve plate picking mechanism base, negative pressure suction head and valve plate thickness measuring device, etc. During work, the negative pressure suction head sucks the valve plate, moves and loads the valve plate into the positioning pin of the sliding material plate, the valve plate is moved and loaded onto the valve plate thickness measuring mechanism to measure the thickness, and the qualified product is transferred to the turntable assembly by moving and loading manipulator to complete the subsequent assembly link on the turntable. However, this design is not suitable for assembly line with carrier circulating on ring track (during assembly, the carrier circulates on ring track according to set steps, and valve plate, valve body and other parts are sequentially sleeved on positioning rod of carrier to make pre-assembled part, which is unloaded at unloading station and then moved to next link for fastening), and the structure is relatively complex. SUMMARY

[0005] In order to overcome the deficiencies in the prior art, the utility model provides a valve plate assembly detection equipment, which sets a specific partition plate at the valve plate assembly station and sets a valve plate thickness detection device at the end of the partition plate. The valve plate is first dropped onto the partition plate and measured at the end of the partition plate, instead of being measured in thickness together with the valve body, so that the problem of misjudgment caused by size tolerance of valve body can be avoided.

[0006] The technical scheme of the utility model is as follows:

[0007] Valve plate assembly detection equipment, including carrier circulation track module;The carrier circulation track module includes a circulation track, and the circulation track is provided with a carrier which can move in a set process cycle;The carrier has a positioning rod;The circulation track is provided with a valve plate assembly station and a valve body assembly station along the line;At the valve plate assembly station, the upper part of the circulation track is provided with a valve plate partition plate, the valve plate partition plate is composed of two parts, and the two parts have a channel so that the positioning rod can pass through;The end of the valve plate partition plate is provided with a valve plate thickness detection device;The upper part of the valve plate partition plate is provided with a piece counting device, the piece counting device includes a moving mechanism and a group of negative pressure suction heads, correspondingly, the valve plate assembly station is also provided with a valve plate magnetic force separating device, and the valve plate magnetic force separating device has a group of material rods;When working, the piece counting device picks up the valve plate from the valve plate magnetic force separating device, and the valve plate is sleeved on the positioning rod of the carrier;When the valve plate is sleeved on the positioning rod, it falls on the valve plate partition plate and then falls on the carrier after thickness detection.

[0008] Compared with the prior art, the valve plate assembly station is provided with a valve plate partition plate and a valve plate thickness detection device which are used in pairs, the valve plate partition plate is arranged above the circulation track, the valve plate thickness detection device is arranged above the end of the valve plate partition plate, after the piece counting machine sleeves the valve plate on the positioning rod of the carrier, the valve plate falls on the valve plate partition plate instead of directly falling on the carrier, when the carrier moves below the valve plate thickness detection device, the valve plate thickness detection device measures the thickness of the valve plate, with the movement of the carrier, the qualified valve plate falls on the carrier after leaving the valve plate partition plate, since the valve plate is not combined with the valve body during measurement, the problem of misjudgment caused by the size tolerance of the valve body is effectively avoided.

[0009] As an optimization, in the foregoing valve plate assembly detection equipment, the valve plate partition plate includes a valve plate carrier plate and a detection reference tool plate connected with the valve plate carrier plate. The detection reference tool plate is arranged to make the end structure of the valve plate partition plate stable, and deformation of the partition plate can be prevented from affecting detection.

[0010] As an optimization, in the foregoing valve plate assembly detection equipment, the valve plate carrier plate is fixedly installed on the circulation track through a group of struts. The valve plate carrier plate is connected with the circulation track through the struts, and has the advantage of easy implementation.

[0011] As an optimization, in the foregoing valve plate assembly detection equipment, the detection reference tool plate is fixedly installed on the circulation track through a height measuring tool support. The detection reference tool plate is connected with the circulation track through the height measuring tool support, is easy to manufacture, and is conducive to the implementation of the utility model.

[0012] As an optimization, the aforementioned valve plate assembly and testing equipment has two valve plate assembly stations along the circulating track: a lower valve plate assembly station and an upper valve plate assembly station. These stations are arranged sequentially. Therefore, it can be used when valve plates need to be assembled on both sides of the valve body, or when valve plate assembly only needs to be performed on the upper or lower side of the valve body, making the equipment widely applicable.

[0013] As an optimization, the aforementioned valve plate assembly and testing equipment includes a valve body loading robot at the valve body assembly station. This robot grips the raw valve body and places it onto the positioning rod of the carrier. Correspondingly, the valve body assembly station also includes a valve body visual inspection device and a valve body correction device. The correction device comprises a valve body transfer robot, a valve body positioning fixture, and a valve body flipping robot. The visual inspection device is positioned above the loading robot and can inspect the valve body gripped by the loading robot for both forward and reverse orientations. The transfer robot moves the valve body between the carrier and the positioning fixture. The flipping robot flips the valve body on the positioning fixture. This design prevents defective valve bodies with incorrect orientation from flowing into the next assembly stage, improving equipment reliability. Furthermore, the layout is reasonable and the structure is compact. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as a basis for understanding the present invention. In the following embodiments, any content not described in detail can be implemented using conventional techniques in the art.

[0020] Example (see) Figures 1-4 ):

[0021] This embodiment provides a valve plate assembly and testing device for assembling a shock absorber recovery valve. When assembling the shock absorber recovery valve, a pre-assembled recovery valve component is first produced using the automated valve assembly equipment of this embodiment, and then transferred to the next stage for fastening.

[0022] In this embodiment, the valve plate assembly and testing equipment includes a carrier circulation track module; the carrier circulation track module includes a circulation track 1, on which a carrier 2 is provided that can circulate according to a set step; the carrier 2 has a positioning rod 201; valve plate assembly station and valve body assembly station are provided along the circulation track 1; at the valve plate assembly station, a valve plate partition 3 is provided above the circulation track 1, the valve plate partition 3 is composed of two parts, and there is a channel between the two parts to allow the positioning rod 201 to pass through; the end of the valve plate partition 3 A valve plate thickness detection device 6 is provided above the end; a counting device 4 is provided above the valve plate partition 3. The counting device 4 includes a moving mechanism and a group of negative pressure suction heads 401. Correspondingly, the valve plate assembly station also has a valve plate magnetic separation device 5. The valve plate magnetic separation device 5 has a group of material rods 501. During operation, the counting device 4 picks up the valve plate from the valve plate magnetic separation device 5 and puts the valve plate onto the positioning rod of the carrier 2. After the valve plate is put onto the positioning rod 201, it falls onto the valve plate partition 3. After the thickness is detected, it falls back onto the carrier 2. Because the valve plate assembly station is equipped with valve plate partition 3, the valve plates do not fall directly onto the carrier 2, but first onto the valve plate partition 3. The carrier 2 moves according to the set steps. With each step, a valve plate is fitted onto the positioning rod 201. When the carrier 2 moves below the valve plate thickness detection device 6, the valve plate thickness detection device 6 measures the total thickness of the valve plates to determine if there are too many or too few plates. If the detection result is unqualified, the unqualified products are transferred to the defective product placement area by the matching unloading machinery during the unloading process.

[0023] In this embodiment, the valve plate partition 3 includes a valve plate carrier plate 301 and a detection reference fixture plate 302 connected to the valve plate carrier plate 301. During operation, the valve plate thickness detection device 6 presses down to measure the total thickness of the valve plates on the detection reference fixture plate 302 to accurately determine the number of valve plates.

[0024] In this embodiment, in order to ensure structural stability and ease of implementation, the valve plate carrier plate 301 is fixedly installed on the circulation track 1 by a group of support columns 303.

[0025] In this embodiment, in order to ensure structural stability and ease of implementation, the detection reference fixture plate 302 is fixedly installed on the circulating track 1 by the height measuring fixture support 304.

[0026] In this embodiment, the circulating track 1 has two valve plate assembly stations along its line: a lower valve plate assembly station and an upper valve plate assembly station. The lower valve plate assembly station, valve body assembly station, and upper valve plate assembly station are arranged sequentially. Therefore, the valve plate assembly and testing equipment of this invention can be used to assemble products with valve plates on both sides of the valve body, or products with valve plates on only one side of the valve body. In this embodiment, the valve plate assembly and testing equipment is used to assemble a shock absorber recovery valve. Ten valve plates need to be assembled on the lower side of the valve body, and twelve valve plates need to be assembled on the upper side. Therefore, at the lower valve plate assembly station, the counting device 4 has ten negative pressure suction heads 401, while at the upper valve plate counting station, the counting device has twelve negative pressure suction heads.

[0027] In this embodiment, the circulating track 1 is sequentially equipped with a lower limit plate assembly station, a lower valve plate assembly station, a valve body assembly station, an upper valve plate assembly station, an upper limit plate assembly station, a demagnetization station, and a material unloading station. During operation, the lower limit plate, lower valve plate, valve body, upper valve plate, and upper limit plate are sequentially fitted onto the positioning rod of the carrier 2 to form a pre-assembled part. When the pre-assembled part moves with the carrier 2 to the demagnetization station, the demagnetization device 7 demagnetizes it. When it moves to the material unloading station, if the valve plate thickness is not up to standard, the matching material unloading machine will transfer the unqualified pre-assembled part to the defective product placement area. If the valve plate thickness is up to standard, the matching material unloading machine will transfer the pre-assembled part to the designated station of the next assembly stage.

[0028] In this embodiment, the valve body assembly station is equipped with a valve body loading robot 8, which is used to grasp raw valve bodies and place them onto the positioning rod 201 of the carrier 2. Correspondingly, the valve body assembly station is also equipped with a valve body visual inspection device 9 and a valve body correction device. The valve body correction device includes a valve body transfer robot 10, a valve body positioning fixture 11, and a valve body flipping robot 12. The valve body visual inspection device 9 is located above the valve body loading robot 8 and can perform forward and reverse detection on the valve body grasped by the valve body loading robot 8. The valve body transfer robot 10 can transport the valve body between the carrier 2 and the valve body positioning fixture 11. The valve body flipping robot 12 is used to flip the valve body on the valve body positioning fixture 11. During operation, the valve body loading robot 8 grabs the raw valve body and puts it onto the positioning rod 201 of the carrier 2. If the valve body vision inspection device 8 detects that the valve body grabbed by the valve body loading robot 8 is facing the wrong direction, the valve body transfer robot 10 transfers the valve body to the valve body positioning fixture 11, and the valve body flipping robot 12 flips it over. Then the valve body transfer robot 10 puts the flipped valve body back onto the positioning rod 201 of the carrier 2.

Those skilled in the art, based on the disclosure of this application, can add, reduce, or combine the disclosed technical features in the foregoing general description and / or specific embodiments (including examples) without departing from the constituent elements of the utility model, to form other technical solutions within the protection scope of this application.
