Description

Technical Field

[0001] The present application relates to the technical field of product processing equipment, and more particularly to a positioning device and processing equipment. Background Art

[0002] In some automated processing processes, jigs are needed to clamp products and flow them so that different processing stations can process the products. For products with higher processing precision, jigs need to be accurately positioned at some processing stations. The general positioning device is inserted into the jig through a pin, so a clearance fit is required between the pin and the jig. The gap between the pin and the jig generally has a certain width to allow the pin to be inserted into the jig, but also allows the jig to move relative to the pin along the X-axis or Y-axis. When the pin adopts a conical structure, since the pin cannot be fully inserted into the jig, the pin will support the jig, resulting in a gap between the positioning device and the jig in the Z-axis direction, making it impossible for the positioning device to accurately position the jig. Utility Model Content

[0003] In view of this, the present application provides a positioning device to solve the problem that the positioning device cannot accurately position the fixture.

The positioning pin is disposed on the top surface of the bracket, and the positioning pin includes a tapered portion for transmitting into a first through-hole of a spring. A pull-down mechanism is disposed on the bracket, and the pull-down mechanism is configured to apply a force to the jig to bring the jig closer to the top surface of the bracket, and to cause the spring on the jig to elastically deform under the support of the tapered portion.

[0005] In the positioning device of the above embodiment, when the jig is placed on the top surface of the bracket, the tapered portion of the locating pin is partially embedded in the spring clip, and the side wall of the spring clip's first through-hole contacts the tapered portion, causing the tapered portion to position the spring clip along the X- and Y-axis directions, and the tapered portion also positions the jig. Simultaneously, a force is applied to the jig by the blanking mechanism, causing the spring clip supporting the jig with the locating pin to elastically deform, allowing the jig to approach the top surface of the bracket, thereby reducing the gap between the jig and the bracket in the Z-axis direction, thereby achieving the effect of accurately positioning the jig in multiple directions.

[0011] In the above embodiment, the first plate and the second plate are spaced apart to achieve installation of the driver in the bracket.

[0012] In some embodiments, the positioning device further includes a positioning block, which is located on the top surface of the bracket. The positioning block is used to support the jig and limit the distance between the jig and the bracket.

[0013] In the above embodiment, the jig is supported by the positioning block to limit the distance between the jig and the bracket.

[0014] In some embodiments, the number of the positioning blocks is at least two.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0035] It should be understood that the dimensions of the structures shown in the drawings are provided for better understanding and more convenient description, and the present application is not limited to the dimensions shown in the drawings. In order to make the present application clear, elements not related to the description are omitted from the details of this specification.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0037] In the process of some product processing, such as polishing and drilling of mobile phone frames, it is necessary to use a jig to fix the inner side of the mobile phone frame so as to facilitate the processing of the outer side of the mobile phone frame. Due to the high processing precision of the mobile phone frame, the jig needs to be accurately fixed during processing. Figure 1 As shown, a spring piece 22 is provided at the bottom of the jig 20 so as to adjust the position of the jig 20 through elastic deformation of the spring piece 22 .

[0038] An embodiment of the present application provides a positioning device, comprising: a bracket, a positioning pin, and a feeding mechanism. The bracket includes a top surface for supporting a jig. The positioning pin is disposed on the top surface of the bracket, and the positioning pin includes a tapered portion for being embedded in a first through hole of a spring. A pull-down mechanism is disposed on the bracket, and the pull-down mechanism is configured to apply a force to the jig to bring the jig closer to the top surface of the bracket and to cause the spring on the jig to elastically deform under the support of the tapered portion.

[0039] In the positioning device of the above embodiment, when the jig is placed on the top surface of the bracket, the tapered portion of the locating pin is partially embedded in the spring clip, and the side wall of the spring clip's first through-hole contacts the tapered portion, causing the tapered portion to position the spring clip along the X- and Y-axis directions, and the tapered portion also positions the jig. Simultaneously, a force is applied to the jig by the blanking mechanism, causing the spring clip supporting the jig with the locating pin to elastically deform, allowing the jig to approach the top surface of the bracket, thereby reducing the gap between the jig and the bracket in the Z-axis direction, thereby achieving the effect of accurately positioning the jig in multiple directions.

[0040] The Z-axis is the direction in which the bracket and the fixture are sequentially arranged and is perpendicular to the top surface of the bracket. The X-axis, Y-axis, and Z-axis are perpendicular to each other, and at least one of the X-axis and Y-axis directions is perpendicular to the inner sidewall of the first through hole 221.

[0041] The following will describe some embodiments of the present application in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0042] In some embodiments, the processing equipment includes a processing device (not shown), a feeding device (not shown), a jig 20, and a positioning device 10. The processing device includes a processing area. The feeding device is located on one side of the processing device, the jig 20 is mounted on the feeding device, and the positioning device 10 is located within the processing area. During operation, the jig 20 clamps the product (not shown). The feeding device transports the jig 20, carrying the product to be processed, to the processing area of ​​the processing device. The positioning device 10 precisely positions the jig 20 within the processing area, allowing the processing device to process the product.

[0043] In some embodiments, the jig 20 is part of a processing device.

[0044] In other embodiments, the jig 20 is a component that is detachably mounted on the feeding device.

[0045] In some embodiments, the feeding device simultaneously conveys multiple jigs 20 so that the multiple jigs 20 pass through the processing area in sequence, and the positioning device 10 and the processing device operate continuously respectively, so as to realize the function of the processing equipment to accurately process multiple products.

[0046] In some embodiments, the feeding device is a turntable, and the fixture 20 is fixed on the turntable.

[0047] In other embodiments, the feeding device is a slide rail, the jig 20 is slidably set on the slide rail, and multiple jigs 20 are interconnected by a conveyor belt or a conveyor chain, and the conveyor belt or the conveyor chain can synchronously drive the multiple jigs 20 to slide.

[0048] See also Figure 1 The side of the jig 20 is used to contact and fix the product. The bottom of the jig 20 is provided with a blind hole 21 and a spring 22. The spring 22 covers the blind hole 21. The blind hole 21 can provide space for the spring 22 to elastically deform toward the inside of the jig 20. The spring 22 is provided with a first through hole 221, which is connected to the blind hole 21.

[0049] See also Figure 2 and Figure 3 The positioning device 10 includes a bracket 11, a positioning pin 12 and a pull-down mechanism 13. The positioning pin 12 is arranged on the top surface of the bracket 11. The positioning pin 12 includes a tapered portion 121. The pull-down mechanism 13 is arranged on the bracket 11.

[0050] When the feeding device transfers the jig 20 to the processing area, the feeding device also places the jig 20 on the bracket 11. Figure 3 The tapered portion 121 of the positioning pin 12 is inserted into the first through hole 221, and the tapered portion 121 supports the spring 22 through the side wall of the first through hole 221. The tapered portion 121 also supports the jig 20, thereby achieving the effect of the positioning device 10 carrying the jig 20. In addition, because the tapered portion 121 limits the side wall of the first through hole 221, the tapered portion 121 can limit the first through hole 221 along the X-axis and Y-axis directions respectively. At the same time, the pull-down mechanism 13 applies a force to the jig 20 so that the jig 20 tends to move toward the bracket 11. The jig 20 simultaneously drives the spring piece 22 to apply pressure to the conical portion 121. The spring piece 22 is elastically deformed toward the blind hole 21 under the support of the conical portion 121, so that the jig 20 can move close to the bracket 11, thereby helping to reduce the gap between the bracket 11 and the jig 20 in the Z-axis direction, so as to achieve the effect of the positioning device 10 accurately positioning the jig 20.

[0051] At the same time, the elastic contact between a part of the spring piece 22 and a part of the tapered portion 121 helps reduce the contact area between the jig 20 and the positioning device 10, and reduces the risk of collision between the jig 20 and the positioning device 10, thereby reducing the wear of the positioning device 10 and the jig 20, and helping to increase the service life of the positioning device 10 and the jig 20.

[0052] It can be understood that when part of the tapered portion 121 passes through the first through hole 221, the blind hole 21 can also accommodate part of the tapered portion 121 to avoid interference between the tapered portion 121 and the jig 20, resulting in the tapered portion 121 directly contacting the jig 20 and supporting the jig 20, which makes it impossible to adjust the distance between the jig 20 and the bracket 11.

[0053] In some embodiments, the positive direction of the Z axis is the direction in which gravity acts vertically upward.

[0054] In other embodiments, the positive direction of the Z axis is arranged to intersect the direction of gravity.

[0055] In other embodiments, the X-axis and the Y-axis are respectively perpendicular to the Z-axis, and the X-axis and the Y-axis are intersecting at any angle except 90°.

[0056] In some embodiments, the shape of the first through hole 221 and the cross-section of the tapered portion 121 perpendicular to the Z-axis are similar polygons, so that the side of the tapered portion 121 can be completely fitted with the side wall of the first through hole 221, which helps to reduce the risk of positional displacement between the first through hole 221 and the tapered portion 121, thereby achieving the effect of improving the precise positioning of the tapered portion 121 on the side wall of the first through hole 221.

[0057] Exemplarily, the first through hole 221 is a circular hole, a triangular hole or a square hole, and the tapered portion 121 is in a cone shape, a triangular pyramid shape or a quadrangular pyramid shape corresponding to the first through hole 221 .

[0058] When the first through hole 221 is a square hole, the X-axis and the Y-axis directions are respectively perpendicular to two adjacent inner sidewalls of the first through hole 221 .

[0059] In some embodiments, the positioning pin 12 is detachably connected to the bracket 11 so as to facilitate replacement of different positioning pins 12 according to the spring pieces 22 of different first through holes 221 .

[0060] In some embodiments, the number of blind holes 21 of the jig 20 is two or more, and the number of spring clips 22 and positioning pins 12 are consistent with the number of through holes. Compared with the jig 20 having only one blind hole 21 and one spring clip 22, two or more positioning pins 12 correspond one-to-one with the spring clips 22, so that multiple positioning pins 12 can jointly position the jig 20, which helps to reduce the risk of the jig 20 rotating around one positioning pin 12 as a fulcrum, thereby achieving the effect of improving the stability of the positioning pin 12 in positioning the jig 20.

[0061] In some embodiments, the spring piece 22 is detachably connected to the fixture 20 by bolt connection or the like, so that when the elasticity of the spring piece 22 decreases after multiple operations, a new spring piece 22 can be replaced.

[0062] In some embodiments, see Figure 4 The jig 20 includes a second through hole 23 and a protrusion 231. The second through hole 23 passes through the jig 20 along the Z-axis direction. The protrusion 231 is located in the second through hole 23. The protrusion 231 is connected to the side wall of the second through hole 23 on one side along the X-axis or Y-axis direction, and there is a gap between the protrusion 231 and the side wall on the other side of the second through hole 23 to allow part of the pull-down mechanism 13 to pass through the second through hole 23.

[0063] See also Figure 2 、 Figure 5 and Figure 6 The bracket 11 includes a first plate 111, a second plate 112 and a connecting rod 113. The first plate 111 and the second plate 112 are arranged opposite to each other along the Z-axis direction. The positioning pin 12 is arranged on the side of the first plate 111 away from the second plate 112. The connecting rod 113 is fixedly connected to the first plate 111 and the second plate 112 respectively. The pull-down mechanism 13 includes a pull rod 131, a pressure rod 132 and a driver 133. The driver 133 is arranged between the first plate 111 and the second plate 112. The pull rod 131 is connected to the driver 133, and a portion of the pull rod 131 passes through the first rod and extends to the outside of the bracket 11. The pressure rod 132 is located at the top of the pull rod 131, and a portion of the pressure rod 132 extends to the outside of the pull rod 131.

[0064] When the feeding device places the jig 20 from top to bottom on the bracket 11 until the positioning pin 12 supports the spring piece 22, part of the pull rod 131 and the pressure rod 132 move relative to the jig 20 in the second through hole 23, and the pressure rod 132 is located above the protrusion 231. At this time, the projections of the pressure rod 132 and the protrusion 231 in the Z-axis direction do not overlap. The driver 133 drives the pull rod 131 to rotate relative to the bracket 11 and the jig 20, and synchronously drives the pressure rod 132 to rotate so that the projection of the pressure rod 132 and the protrusion 231 in the Z-axis direction at least partially overlap. The driver 133 then drives the pull rod 131 to contract, so as to synchronously drive the pressure rod 132 to move close to the first plate 111, and make the pressure rod 132 contact with the protrusion 231 until the pressure rod 132 presses down the protrusion 231, so that the protrusion 231 synchronously drives the jig 20 to move close to the first plate 111, so as to achieve the function of reducing the gap between the jig 20 and the bracket 11 in the Z-axis direction.

[0065] When the processing device completes processing the product, the driver 133 drives the pull rod 131 to extend and simultaneously drives the pressure rod 132 to move away from the first plate 111, so that the pressure rod 132 cancels the downward pressure on the protrusion 231 until the pressure rod 132 separates from the protrusion 231. After the pressure rod 132 separates from the protrusion 231, the driver 133 drives the pull rod 131 to rotate, and the driver 133 simultaneously drives the pressure rod 132 to rotate and reset, so that the feeding device can remove the jig 20 with the processed product fixed on the bracket 11, and then place the jig 20 with the product to be processed fixed on the bracket 11.

[0066] In some embodiments, when the projections of the pressing rod 132 and the protrusion 231 in the Z-axis direction do not overlap, the pressing rod 132 rotates relative to the bracket 11 and the fixture 20 outside the second through hole 23 .

[0067] In other embodiments, the pressing rod 132 always rotates relative to the fixture 20 within the second through hole 23 .

[0068] In some embodiments, see 4 , there are two protrusions 231 in the second through hole 23 , and the two protrusions 231 are arranged opposite to each other along the X-axis or Y-axis direction, and there is a gap (not marked) between the two protrusions 231 to allow part of the pull rod 131 and the pressure rod 132 to pass through. Figure 2 The pressure rod 132 has two opposite ends. The middle portion of the pressure rod 132 (i.e., the portion between the two ends) is connected to the top of the pull rod 131. The two ends of the pressure rod 132 extend to the outside of the pull rod 131 in a direction perpendicular to the Z axis. When the driver 133 synchronously drives the pressure rod 132 to rotate, one end of the pressure rod 132 at least partially overlaps with the projection of one protrusion 231 in the Z axis direction, and the other end of the pressure rod 132 at least partially overlaps with the projection of the other protrusion 231 in the Z axis direction, so that the pressure rod 132 acts on the two protrusions 231 at the same time, and the two protrusions 231 synchronously drive the jig 20 to move closer to the jig 20. The provision of two protrusions 231, compared to having only one protrusion 231, helps reduce the risk of the jig 20 tilting due to uneven force.

[0069] Furthermore, the number of the second through holes 23 is two or more, and the second through holes 23 are arranged along the X-axis or Y-axis direction. The number of the pull rods 131, the pressure rods 132, and the drivers 133 is the same as the number of the second through holes 23. By having two or more pressure rods 132 act on the jig 20 respectively, the pressure rods 132 can improve the uniformity of the jig 20, thereby helping to reduce the risk of the jig 20 tilting.

[0070] In some embodiments, the pull rod 131 and the pressure rod 132 are detachably arranged so that different pressure rods 132 can be replaced according to different jigs 20 , thereby enabling the pull-down mechanism 13 to pull down different jigs 20 .

[0071] In some embodiments, the driver 133 is a rotating cylinder and a telescopic cylinder connected to each other. The rotating cylinder is connected to the frame, and the telescopic air rod is connected to the pull rod 131, or the telescopic air rod is connected to the frame, and the rotating cylinder is connected to the pull rod 131.

[0072] In some embodiments, see Figure 2 and Figure 5 The positioning device 10 also includes a positioning block 14 located on the first plate 111. When the pull-down mechanism 13 acts on the jig 20 to move the jig 20 toward the bracket 11, the positioning block 14 supports the jig 20 to limit the distance between the jig 20 and the bracket 11. Therefore, when the elastic force of the spring 22 or the pressure of the pressure rod 132 is inconsistent, the distance between each jig 20 and the bracket 11 is equalized, thereby achieving the effect of accurately positioning the jig 20 in the Z-axis direction.

[0073] In some embodiments, the number of positioning blocks 14 is two or more, and the positioning blocks 14 are arranged along the X-axis or Y-axis direction corresponding to the second through holes 23 to improve the uniformity of the positioning blocks 14 supporting the fixture 20, which helps to reduce the risk of the fixture 20 tilting.

[0074] In some embodiments, see Figure 2 and Figure 5 One positioning pin 12 corresponds to two positioning blocks 14. In the X-axis direction, the positioning pin 12 and the pressure rod 132 are located between the two positioning blocks 14, so that when the positioning device 10 positions the jig 20, the positioning blocks 14 can support the jig 20 on both sides of the positioning pin 12 and the pressure rod 132 to reduce the risk of the jig 20 tilting.

[0075] In other embodiments, the pull-down mechanism 13 includes a suction cup (not shown) disposed on the top surface of the bracket 11. When the feeding device places the jig 20 on the bracket 11, the suction cup applies an adsorption effect to the jig 20, thereby enabling the jig 20 to move closer to the bracket 11.

[0076] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the substantive scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
