Description

Technical Field

[0001] This utility model relates to the field of product assembly, specifically to equipment for supplying product accessories. Background Technology

[0002] Plate-shaped parts have connection holes, which are smooth holes. Internally threaded components, in the form of rings, need to be fitted into these connection holes using a press-fit method. For example... Figure 8 The plate-shaped parts and internally threaded parts shown are shown. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a mechanism that can automatically supply internally threaded parts, providing hardware conditions for the automatic installation of internally threaded parts onto plate-shaped parts.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic supply mechanism for accessories, including a feeding device, a product transfer device, and a product acquisition device. The feeding device has a product feeding channel at its conveying end, and the product transfer device has a product positioning notch that can connect with the product feeding channel. Below the product positioning notch is a lifting and lowering top-loading device. The product acquisition device has a product positioning rod with a tapered end. The top-loading device has a clearance hole at its end. The product positioning rod and the top-loading device are arranged vertically and vertically, with the tapered end of the product positioning rod located above the positioning notch. The outer diameter of the tapered end of the product positioning rod is less than or equal to the inner diameter of the clearance hole, and the inner diameter of the positioning notch is greater than or equal to the outer diameter of the end of the top-loading device with the clearance hole.

[0005] The feeding device provides an internally threaded component, which enters the product positioning notch along the product feeding channel. The ejector device rises, and its end with a clearance hole pushes the internally threaded component out of the product positioning notch, causing it to fit onto the tapered end of the product positioning rod. Simultaneously, the tapered end extends into the clearance hole. The ejector device then descends and resets to below the product positioning notch, with the internally threaded component now fitted onto the product positioning rod.

[0006] The product transfer device includes a fixed transfer platform, a translation plate connected to a horizontal cylinder, and a limiting block fixed on the transfer platform. The product positioning notch is located on the translation plate, which is positioned alongside the limiting block above the transfer platform. The transfer platform has a through hole for a feeding device to pass through. The feeding device supplies an internally threaded component to the product positioning notch via a product feeding channel. A sensor mounted on the transfer platform detects the presence of the internally threaded component in the notch. The horizontal cylinder drives the translation plate, which carries the internally threaded component along the transfer platform until it reaches above the through hole. The feeding device rises, passes through the through hole, and pushes the internally threaded component out of the product positioning notch, causing it to fit onto the tapered end of the product positioning rod. Simultaneously, the tapered end extends into the clearance hole.

[0007] Alternatively, the top material device is a vertical cylinder, with the piston rod of the vertical cylinder fixedly connected to the central turntable, and the clearance hole is provided at one end of the cylinder body of the vertical cylinder.

[0008] The tapered end of the product positioning rod is petal-shaped, which helps the internal threaded parts to be stably fitted onto the product positioning rod and prevents the internal threaded parts from falling down along the product positioning rod.

[0009] The product positioning rod is fixed to the product acquiring bracket, which is equipped with a vertical cylinder connected to a material feeding plate. The material feeding plate has a feeding port, and the product positioning rod protrudes downwards from the feeding port. The internally threaded component is fitted onto the portion of the product positioning rod that protrudes downwards from the feeding port. The ejector device rises, ejecting the internally threaded component from the product positioning notch and fitting it onto the tapered end of the product positioning rod. The internally threaded component is located below the material feeding plate and the feeding port. The product acquiring device moves to the installation position. After the product positioning rod aligns with the connecting hole of the plate-like part, the vertical cylinder actuates, driving the material feeding plate. The material feeding plate pulls the internally threaded component off the product positioning rod and presses it into the connecting hole of the plate-like part.

[0010] The product receiving bracket is equipped with a guide block located beside the product positioning rod, which works in conjunction with the material feeding plate. An internally threaded component, fitted onto the product positioning rod, has its outer side abutting against one end face of the guide block. Alternatively, the guide block can be a permanent magnet or an electromagnet, which attracts the internally threaded component, stabilizing it on the product positioning rod.

[0011] The product acquiring bracket is equipped with a vacuum nozzle, which is spatially perpendicular to the product positioning rod. The product acquiring bracket is hinged to a connecting arm, which has a tilting cylinder. The piston rod of the tilting cylinder is connected to a hinge seat on the product acquiring bracket, driving the product acquiring bracket to rotate relative to the connecting arm. The connecting arm is connected to an XYZ 3D motion system. The tilting cylinder acts on the hinge seat, causing the product acquiring bracket to rotate 90 degrees, changing the vacuum nozzle from a horizontal to a vertical position, and the product positioning rod from a vertical to a horizontal position. Driven by the XYZ 3D motion system, the vacuum nozzle acquires plate-shaped parts from the plate-shaped parts supply and conveys them to the installation station. After the plate-shaped parts are positioned at the installation station, the product acquiring bracket rotates 90 degrees under the drive of the tilting cylinder, changing the product positioning rod from a horizontal to a vertical position. After the product positioning rod is aligned with the connecting hole of the plate-shaped part, the vertical cylinder is activated to drive the material-pulling plate. The material-pulling plate pulls the internal threaded part off the product positioning rod and presses it into the connecting hole of the plate-shaped part.

[0012] Technical effects of this utility model:

[0013] First, it can automatically feed materials and put the internal threaded parts onto the product positioning rod of the product acquisition device.

[0014] Secondly, the petal-shaped structure and guide block design can stabilize the internal threaded parts on the product positioning rod;

[0015] Third, the presence of the flipping cylinder enables the product acquisition device to rotate 90 degrees, thus having the dual function of acquiring plate-shaped parts and internally threaded parts. Attached Figure Description

[0031] like Figure 1 , Figure 3 , Figure 4 , Figure 6 An automatic supply mechanism for accessories includes a feeding device 10, a product transfer device 20, and a product acquisition device 30. The feeding device has a product feeding channel 11 at its conveying end. The product transfer device has a product positioning notch 221 that can connect with the product feeding channel. Below the product positioning notch 221 is a lifting and lowering top material device 25. The product acquisition device includes a product positioning rod 31 with a tapered end. The top material device has a clearance hole 251 at its end. The product positioning rod and the top material device are arranged vertically and vertically. The tapered end of the product positioning rod is located above the product positioning notch 221. The outer diameter of the tapered end of the product positioning rod is less than or equal to the inner diameter of the clearance hole. The inner diameter of the positioning notch is greater than or equal to the outer diameter of the end of the top material device with the clearance hole.

[0032] like Figure 3 , Figure 4 The product transfer device 20 includes a fixed transfer platform 21, a translation plate 22 connected to a horizontal cylinder 23, and a limiting block 24 fixed on the transfer platform. The product positioning notch 221 is opened on the translation plate. The translation plate and the limiting block are arranged side by side above the transfer platform. The transfer platform is provided with a through hole for the material feeding device to pass through.

[0033] The top material device 25 is a vertical cylinder. The piston rod of the vertical cylinder is fixedly connected to the central turntable 21. The clearance hole 251 is provided at one end of the cylinder body of the vertical cylinder.

[0034] like Figure 6 The tapered end of the product positioning rod 31 is petal-shaped 311.

[0035] The product positioning rod 31 is fixed on the product acquisition bracket 32. A vertical cylinder 33 is installed on the product acquisition bracket. The vertical cylinder is connected to the material feeding plate 34. The material feeding plate is provided with a material feeding port 341. The product positioning rod protrudes downward from the material feeding port. The internal threaded part 90 is sleeved on the part of the product positioning rod that protrudes downward from the material feeding port.

[0036] The product acquisition bracket 32 ​​is provided with a guide block 35, which is located next to the product positioning rod 31 and is used in conjunction with the material feeding plate 34; the internal threaded part 90, which is sleeved on the product positioning rod, abuts against one end face of the guide block.

[0037] like Figure 5 The product acquisition bracket 32 ​​is equipped with a vacuum nozzle 36, which is spatially perpendicular to the product positioning rod 31. The product acquisition bracket 32 ​​is hinged to the connecting arm 40, which is equipped with a flipping cylinder 41. The piston rod of the flipping cylinder is connected to the hinge seat 37 on the product acquisition bracket, driving the product acquisition bracket to rotate relative to the connecting arm.

[0038] like Figure 2 The feeding device 10 selects a vibratory feeder to provide an internally threaded component 90. The internally threaded component enters the product positioning notch 221 along the product feeding channel 11. The ejector device 25 rises, and the end with the relief hole 251 pushes the internally threaded component 90 out of the product positioning notch 221, causing the internally threaded component to fit onto the tapered end of the product positioning rod 31. At the same time, the tapered end extends into the relief hole 251. The ejector device 25 descends and resets to below the product positioning notch 221, and the internally threaded component fits onto the product positioning rod.

[0039] The feeding device 10 supplies the internally threaded component 90 to the product positioning notch 221 via the product feeding channel 11. A sensor 26 mounted on the transfer platform 21 detects the presence of the internally threaded component in the product positioning notch. A horizontal cylinder 23 drives a translation plate 22, which moves the internally threaded component 90 along the transfer platform 21 until it reaches above the perforation. The ejector device 25 rises, passes through the perforation, and ejects the internally threaded component from the product positioning notch 221, causing it to fit onto the tapered end of the product positioning rod 31. Simultaneously, the tapered end extends into the clearance hole 251.

[0040] The tapered end of the product positioning rod 31 is petal-shaped, which facilitates the stable mounting of the internally threaded component on the product positioning rod and prevents the internally threaded component from falling down the product positioning rod. The guide block 35 can be a permanent magnet or an electromagnet, which has an adsorption effect on the internally threaded component, making the internally threaded component stable on the product positioning rod 31.

[0041] The ejector device 25 rises, ejecting the internally threaded part 90 from the product positioning notch 221, and placing the internally threaded part onto the tapered end of the product positioning rod 31. The internally threaded part is located below the ejector plate 34 and the ejector port 341. The product acquisition device 30 moves to the installation position. After the product positioning rod 31 aligns with the connecting hole 92 of the plate-shaped part 91, the vertical cylinder 33 actuates, driving the ejector plate 34. The ejector plate removes the internally threaded part from the product positioning rod 31 and presses it into the connecting hole of the plate-shaped part 91.

[0042] The connecting arm 40 is connected to the XYZ three-dimensional motion system. The flipping cylinder 41 acts on the hinge seat 37, causing the product acquisition bracket 32 ​​to rotate 90 degrees, changing the vacuum nozzle 36 from a horizontal to a vertical state, and the product positioning rod 31 from a vertical to a horizontal state. Driven by the XYZ three-dimensional motion system, the vacuum nozzle acquires the plate-shaped part 91 from the plate-shaped part supply and conveys it to the installation station. After the plate-shaped part 91 is positioned at the installation station, driven by the flipping cylinder 41, the product acquisition bracket 32 ​​rotates 90 degrees, and the product positioning rod 31 changes from a horizontal to a vertical state. After the product positioning rod aligns with the connecting hole 92 of the plate-shaped part, the vertical cylinder 33 actuates, driving the material-pulling plate 34. The material-pulling plate pulls off the internal threaded part 90 on the product positioning rod 31 and presses it into the connecting hole 92 of the plate-shaped part.

[0043] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
