Description

Technical Field

[0001] This utility model relates to the field of mobile phone component measurement technology, and in particular to a fixture for rapid dimensional measurement using visual inspection equipment. Background Technology

[0002] Mobile phone components such as SIM card trays and button holders require dimensional measurement after production to distinguish between defective and good products. Currently, measuring these components requires an operator to hold a measuring tool in one hand and the component in the other, recording the results manually. This manual operation is cumbersome and inefficient. Furthermore, manual measurement is prone to errors, making it difficult to sort out defective products. To adapt to industrial automation and improve production efficiency, visual inspection equipment is commonly used to measure the dimensions of various mobile phone components. For example, a visual inspection device for the processing dimensions of mobile phone metal casings (application number 2020230605127) includes a base and a main body of the visual inspection device on the base. One side of the base has a conveying device, and the surface of the base has a placement groove. The main body of the visual inspection device has a photographing device facing the placement groove. The placement slot has two horizontally adjustable plates and two vertically adjustable plates inside. A horizontally adjustable mechanism is located at the bottom of the placement slot, connected to the two horizontally adjustable plates. Two sets of cylinders are symmetrically arranged vertically inside the base. The output ends of both sets of cylinders pass through the placement slot and connect to the two vertically adjustable plates. The adjustable mechanism includes a fixed slot, a rotating motor, a double-acting screw, a fixed seat, and a slide rail. The fixed slot is located inside the base directly below the placement slot. The rotating motor is installed at the end of the fixed slot. One end of the double-acting screw is connected to the output end of the rotating motor, and the other end is rotatably connected to the inner wall of the fixed slot via a rotating joint. Two sets of fixed seats are provided, each threaded to both ends of the double-acting screw. The slide rail is located between the fixed slot and the placement slot, and communicates with both. The two sets of fixed seats pass through the slide rail and connect to the two horizontally adjustable plates. In application, the parts are placed in the placement slot, and the imaging device captures image information of the parts in the placement slot to measure their dimensions.

[0003] However, when measuring the dimensions of parts, the aforementioned visual inspection equipment requires staff to place individual parts in the placement slot to collect images in order to achieve the measurement. It cannot perform batch measurement of parts, so the measurement efficiency is still low and cannot meet the needs of efficient measurement of batch parts.

[0004] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a fixture for rapid dimensional measurement in visual inspection equipment, in order to solve the problem of low measurement efficiency of existing mobile phone parts.

[0006] To achieve its purpose, this utility model adopts the following technical solution:

[0007] A fixture for rapid dimensional measurement using a visual inspection device includes a placement tray. The top surface of the placement tray has a storage groove containing several horizontally arranged material strips. The top surface of each material strip has several grooves for embedding mobile phone components. The bottom of each groove has a through-hole for vertical illumination, and the bottom of the storage groove has a through-hole for vertical illumination corresponding to the position of the through-hole. The two outer side walls of the placement tray at both ends of the material strips are recessed with grooves that communicate with the storage grooves and extend to the outside of the bottom surface of the placement tray. Each groove is a strip-shaped notch extending along the horizontal direction of the material strips, and the length of the notch is less than the maximum distance between the two outermost material strips but greater than the minimum distance between the two outermost material strips. The placement tray has a top block with one end movably inserted into the groove and the other end outside the placement tray, capable of rotating vertically within the groove.

[0008] With the direction of the horizontal arrangement of each material strip as the front-back direction, the placement tray is formed by four side plates and a bottom plate to form a hollow square frame with an open top surface. The hollow cavity of the hollow square frame is the placement slot, and each material strip is arranged on the top surface of the bottom plate in the front-back direction.

[0009] The material strip is a strip-shaped block extending in the left-right direction, and the top surface of the material strip is recessed with several rows of grooves spaced apart in the front-back direction. Each groove row has several grooves spaced apart in the left-right direction. The grooves are the material grooves.

[0010] In the fourth side plate body, the bottom surface of the side plate body on both the left and right sides is provided with a side through groove extending in the front-back direction and passing through in the left and right directions. The bottom surface of the bottom plate is provided with a bottom through hole extending in the front-back direction and passing through in the top and bottom directions on both the left and right sides. The length of the bottom through hole matches the length of the side through groove and is connected and cooperates. The side through groove and the bottom through hole constitute the push groove mentioned above.

[0011] The top material block is a strip-shaped plate extending in the front-back direction. The side edges of the two strip-shaped plates on opposite sides are inserted into the through slots on both sides and extend into the lower through hole. The opposite sides of the two strip-shaped plates are outside the side plate body.

[0012] This invention relates to a fixture for rapid dimensional measurement in visual inspection equipment. In application, components are first inserted into the slots of a material strip, and the strips are arranged sequentially in a storage slot. A placement tray is then placed within the placement slot of the visual inspection equipment. The equipment is activated to acquire image information of the components on the tray, thereby measuring their dimensions. Compared to existing technologies, because the placement tray can hold multiple components, the visual inspection equipment can simultaneously acquire images of each component in batches, enabling batch dimensional measurement and allowing for the selection of defective components, thus improving production efficiency. Furthermore, the top block can simultaneously lift both ends of each material strip, removing it from the storage slot for easy replacement with the next batch of components. It also allows for the replacement of material strips with slots for different components when measuring different parts, broadening its application range. Attached Figure Description

[0017] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0018] A fixture for rapid dimensional measurement in visual inspection equipment, such as Figures 1-4 As shown, it includes a placement tray 1, the top surface of which is provided with a storage groove; specifically, with the direction of the horizontal arrangement of each material strip 2 as the front and back direction, the placement tray 1 is formed by four side plates 11 and a bottom plate 12 to form a hollow square frame with an open top surface, and the hollow cavity of the hollow square frame is the storage groove.

[0019] The storage slot contains several horizontally arranged material strips 2, and the top surface of each material strip 2 has several grooves for embedding mobile phone components. Specifically, each material strip 2 is arranged sequentially on the top surface of the base plate 12 in the front-back direction. The material strip 2 is a strip-shaped block extending in the left-right direction, and the top surface of each material strip 2 has several rows of grooves spaced apart in the front-back direction. Each groove row has several grooves spaced apart in the left-right direction, that is, the grooves are arranged in a matrix on the material strip 2. The grooves are the material grooves. If the component placed in the trough is a button bracket, the button bracket has a mounting block and mounting protrusions. The mounting block is a horizontally arranged strip structure. There are two mounting protrusions, which are spaced apart on the bottom surface of the mounting block. The mounting protrusions have through holes that allow the button to extend out. The bottom surface of the mounting block has a through hole located between the two mounting protrusions. The trough in the figure is a trough for placing the button bracket. The trough corresponding to the button bracket has an upper horn section and an insert section that are connected from top to bottom. The insert section has an upper insert section and a lower insert section. The upper horn section is vertically arranged. The structure is a horn-shaped structure that tapers from top to bottom. The upper embedding section is a strip-shaped groove into which a mounting block is embedded. The bottom of the strip-shaped groove has two embedding slots corresponding to the mounting protrusions on the bottom surface of the mounting block, which are the two embedding slots mentioned above as the lower embedding section. If the component placed in the material slot is a card tray, the card tray has a card plate for the SIM card to lie flat inside and a side plate set perpendicular to the card plate. The card plate has a card slot for the SIM card to be placed inside, and the card plate has a signal hole for the SIM card chip to be exposed within the card slot area. The embedding section is an embedding groove that matches the shape of the card tray. In application, if the component being measured is a button bracket, the mounting protrusion is embedded in the embedding groove, and the mounting block is embedded in the strip-shaped groove. If the component being measured is a card tray, the card tray is embedded in the embedding groove. The upper horn section facilitates the removal of the component from the material slot. The specific structure of the material trough can be set according to the different sizes of the parts, so that different material strips can be set into the material trough with different structures. Since the material strips are stacked in the storage trough, the material strips can be taken out at will and replaced with material strips with the parts to be measured in the next batch. Furthermore, when measuring different parts, material strips with material troughs with corresponding parts structures can also be replaced, which can be applied to the measurement of different parts and has a wider range of applications.

[0020] The bottom of the material trough has a through-hole 100 for vertical illumination, and the bottom of the storage trough has a through-hole 200 for vertical illumination corresponding to the position of the through-hole 100. Specifically, the through-hole 100 is located in the middle of the material trough. If a button bracket is placed in the material trough, the through-hole 100 falls between the two embedded slots and is positioned opposite the opening. If a card holder is placed in the material trough, the through-hole 100 is within the signal hole range. In application, a light source is set on the base of the vision inspection equipment at the position corresponding to the through-hole 400. The method of setting the light source is well known to those skilled in the art and will not be described in detail here. When the imaging device of the vision inspection equipment performs image acquisition, the light source will illuminate the parts in the material trough, making the image acquisition of the parts clearer and the measurement more accurate.

[0021] The two outer walls of the placement tray 1 at both ends of the material strip 2 are recessed with grooves that are connected to the placement groove and extend to the bottom surface of the placement tray 1. The grooves are strip-shaped notches extending along the transverse arrangement direction of each material strip 2. The length of the strip-shaped notches is less than the maximum distance between the two outermost material strips 2 and greater than the minimum distance between the two outermost material strips 2. Specifically, in the four side plates 11, the side plate on the left is the left side plate and the side plate on the right is the right side plate. The bottom surfaces of the left and right side plates are recessed with side through grooves 300 extending in the front-back direction and passing through the left and right sides. The bottom surfaces of the bottom plate 12 are provided with lower through holes 400 extending in the front-back direction and passing through the top and bottom on both the left and right sides. The length of the lower through holes 400 matches the length of the side through grooves 300 and they are connected and cooperate. The side through grooves and the lower through holes constitute the aforementioned grooves. The upper end of the material strip 2 is clamped between the left and right side plates. In application, the push-slot design facilitates the ejection of the material strip 2 from the storage slot, making it easy to replace the material strip 2. Furthermore, the presence of two push-slots allows for easy operation of the left and right ends of the material strip 2, preventing parts from scattering during operation.

[0022] The placement tray 1 is provided with a top material block 3, one end of which is movably inserted into the push groove, and the other end is outside the placement tray 1 and can rotate up and down within the push groove; specifically, the top material block 3 is a strip-shaped plate extending in the front-back direction, with the side edges of the two strip-shaped plates correspondingly inserted into the two side through grooves 300 and extending into the lower through hole 400, and the opposite sides of the two strip-shaped plates being outside the side plate 11, that is, the top material block 3 has an integrally formed lower insertion plate 31 and upper extension plate 32, the lower insertion plate 31... The strip-shaped plate extends in the front-to-back direction, with one end of the two lower insertion plates 31 inserted into the lower through hole 400 from the lower part of the side through groove 300, and the opposite ends of the two lower insertion plates 31 extending out of the placement plate 1. The thickness of the lower insertion plate 31 is the same as the depth of the lower through hole 400 in the vertical direction. The upper extension plate 32 is located on the end of the lower insertion plate 31 facing away from the placement plate 1. The thickness of the upper extension plate 32 is the same as the distance between the bottom of the side through groove 300 and the top surface of the bottom plate 12. In application, the lower insertion plate 31 of the top material block 3 extends from the lower part of the side through groove 300 into the lower through hole 400. The upper insertion plate 32 is embedded in the upper part of the side through groove 300 at one end facing the placement plate 1. Pick up the placement plate 1 and rotate the top material block 3. If the two top material blocks 3 are rotated and set up vertically, the top surface of the lower insertion plate 31 contacts the bottom surface of each material strip 2 and presses down on the placement plate 1. The top material block 3 then lifts up both ends of each material strip, making the replacement of material strip 2 more efficient.

[0023] This invention relates to a fixture for rapid dimensional measurement using a visual inspection device. In application, components are first inserted into the slots of a material strip, and the strips are arranged sequentially in a storage slot. A placement tray is then placed within the storage slot of the visual inspection device. The device is activated to acquire image information of the components on the tray, thereby measuring their dimensions. Compared to existing technologies, because the placement tray can hold multiple components, the visual inspection device can simultaneously acquire images of each component in batches, enabling batch dimensional measurement and allowing for the selection of defective components, thus improving production efficiency. Furthermore, the top block can simultaneously lift both ends of each material strip, ejecting it from the storage slot. This facilitates changing to the next batch of components for measurement and allows for the replacement of material strips with slots for different components, broadening its application range.

[0024] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
