[0044] See also Figure 1 、 Figure 2 and Figure 3 The embodiment of the present invention is a screen printing product comparison inspection jig, comprising a base 100 and a cover 200. The base 100 is provided with a first positioning portion and a placement portion 110. The placement portion 110 is used for placing the product 300 to be compared and for limiting the rotation of the product 300 to be compared. The cover 200 is made of a transparent material and is provided with a second positioning portion and a comparison line 210. The screen printing product comparison inspection jig has at least a detection state. When the screen printing product comparison inspection jig is in the detection state, the first positioning portion and the second positioning portion are positioned and matched to limit the rotation of the cover 200 relative to the base 100. Figure 6 The comparison line 210 is used to compare with the silk-screen pattern 310 on the product 300 to be compared.

[0045] The silk-screened product to be compared can be placed on the placement portion 110, and the cover 200 is assembled on the base 100. The first positioning portion and the second positioning portion are positioned and matched, so that the silk-screen product comparison detection fixture is in a detection state. The transparent cover 200 allows the comparison line 210 on the cover 200 to be compared with the silk-screen pattern 310 on the product to be compared 300. For example, when detecting the four direction marks on the button cap, the corners of the direction mark are compared with the comparison line 210. If the corners of the direction mark coincide with the comparison line 210, it is passed. If the corners of the direction mark do not coincide with the comparison line 210, the product is NG. The operation is simple, the fixture structure is simple, and the cost is low.

[0046] This tool can be used for silk screen inspection on keycaps. Its compact size and light weight make it easy for employees to operate and cost-effective. Its size fits the palm of your hand, allowing one-handed operation. It can be used repeatedly without fatigue and can be removed at any time. This tool is low-cost and poses no safety risks, significantly reducing both time and money costs.

[0047] In some embodiments, see Figure 1 、 Figure 3 and Figure 5 The silk-screen product comparison inspection fixture also has a waiting-for-inspection state. When the silk-screen product comparison inspection fixture is in the waiting-for-inspection state, the base 100 and the cover 200 are staggered, and the placement portion 110 is exposed.

[0048] The initial state of the silk-screen product comparison inspection jig is when it is in the state to be inspected. The placement portion 110 is exposed, making it easy to place the product 300 to be compared on the placement portion 110. The placement portion 110 restricts the rotation of the product 300 to be compared. The cover 200 is assembled on the base 100, and the first positioning portion and the second positioning portion are positioned and matched. The silk-screen product comparison inspection jig is in the inspection state, and the comparison line 210 can be compared with the silk-screen pattern 310 on the product 300 to determine whether the product is qualified. After the comparison is completed, the cover 200 is removed from the base 100, and the inspected product 300 to be compared is removed. The silk-screen product comparison inspection jig switches to the state to be inspected.

[0049] In some embodiments, see Figure 3 The alignment line 210 is a groove. The alignment line 210 is formed by engraving a groove on the cover plate 200, which is easy to process and is not easily scratched or worn during long-term use, making the alignment line 210 strong and durable.

[0050] The comparison line 210 can also be a drawing line, which is convenient for processing. It is convenient to draw the corresponding comparison line 210 according to the silk-screen pattern 310 on the product 300 to be compared, and it is convenient to change the comparison line 210.

[0051] In some embodiments, see Figure 3 and Figure 6, comparison line 210 is a cross. When inspecting the four directional markings on a keycap, the corners of the directional markings are aligned with comparison line 210. If the corners of the directional markings coincide with comparison line 210, the product passes. If they do not, the product fails. By setting comparison line 210 as a cross, all four directional markings on a keycap can be inspected simultaneously, improving inspection efficiency.

[0052] Four comparison lines 210 can also be provided, arranged in a circular array. When testing four directional markings on a keycap, four comparison lines 210 are set corresponding to the four directional markings. The corners of the directional markings are compared with the comparison lines 210. If the corners of the directional markings coincide with the comparison lines 210, the product passes. If they do not, the product fails. This allows simultaneous testing of all four directional markings on a keycap, resulting in high testing efficiency.

[0053] In some embodiments, see Figure 1 、 Figure 2 and Figure 3 The base 100 is provided with a first foolproofing portion, and the cover 200 is provided with a second foolproofing portion. When the silk-screen product comparison inspection jig is in the inspection state, the first and second foolproofing portions cooperate to prevent mistakes, and the comparison line 210 is located on the cover 200 near the base 100. The provision of the first and second foolproofing portions not only facilitates the quick alignment and assembly of the base 100 and the cover 200, but also ensures that the comparison line 210 is located on the cover 200 near the base 100 when the silk-screen product comparison inspection jig is in the inspection state.

[0054] When the silk-screen product comparison inspection jig is in the inspection mode, the comparison line 210 is located on the side of the cover plate 200 close to the base 100. This allows the comparison line 210 to be closer to the silk-screen pattern 310 of the product 300 to be compared, making the comparison between the comparison line 210 and the silk-screen pattern 310 easier. When the silk-screen product comparison inspection jig is in the inspection mode and the comparison line 210 is located on the side of the cover plate 200 away from the base 100, it is necessary to look directly at the cover plate 200 surface to compare the comparison line 210 with the silk-screen pattern 310, which is prone to errors.

[0055] In some embodiments, see Figure 1 、 Figure 2 and Figure 3The first fool-proofing part includes a first fool-proofing surface 140, and the first fool-proofing surface 140 is parallel to the assembly direction of the cover plate 200 and the base 100. The second fool-proofing part includes a second fool-proofing surface 230, and the second fool-proofing surface 230 is parallel to the assembly direction of the cover plate 200 and the base 100. When the base 100 is placed on the ground, the assembly direction of the base 100 and the cover plate 200 is from top to bottom in the vertical direction. After the base 100 and the cover plate 200 are assembled, they are in the detection state. The first fool-proofing surface 140 and the second fool-proofing surface 230 are flat and easy to process. The first fool-proofing surface 140 and the second fool-proofing surface 230 cooperate to prevent fools, which facilitates the rapid alignment and assembly of the base 100 and the cover plate 200, and can also ensure that when the silk-screen product comparison detection fixture is in the detection state, the comparison line 210 is located on the cover plate 200 close to the side of the base 100.

[0056] In some embodiments, see Figure 1 、 Figure 2 and Figure 3 The cover plate 200 is a square plate, with the first foolproof surface 140 located at a corner of the cover plate 200. The base 100 has a square cross-section, and the second foolproof surface 230 is located at a corner of the base 100. The square cross-section of the base 100 and the square cover plate 200, combined with the regular shapes of the base 100 and cover plate 200, facilitate machining. The first foolproof surface 140 and the second foolproof surface 230 cooperate to facilitate quick alignment and assembly of the base 100 and cover plate 200.

[0057] It is small in size and light in weight, easy for employees to operate, low in cost, and the size fits the size of the employee's palm, so it can be operated with one hand. It can be used multiple times without getting tired and can be taken out whenever needed.

[0058] In some embodiments, see Figure 2 The base 100 is provided with a first pick-up and placement groove 150 and a second pick-up and placement groove 160. The first pick-up and placement groove 150 and the second pick-up and placement groove 160 are located on opposite sides of the placement portion 110 and are arranged close to the placement portion 110. The first pick-up and placement groove 150 and the second pick-up and placement groove 160 are respectively provided on opposite sides of the placement portion 110 to facilitate the picking and placing of the product to be compared 300. Use two fingers to hold the product to be compared 300 and place it on the placement portion 110. The fingertips of the two fingers can be inserted into the first pick-up and placement groove 150 and the second pick-up and placement groove 160 respectively, ensuring that the product to be compared 300 is firmly placed on the placement portion 110.

[0059] In some embodiments, see Figure 1 and Figure 2The base 100 is provided with a plurality of supporting portions 170. When the screen printing product comparison detection jig is in a detection state, the plurality of supporting portions 170 support the cover plate 200, and a gap exists between the placing portion 110 and the cover plate 200. The supporting portions 170 can support the cover plate 200, guarantee that a gap exists between the cover plate 200 and the placing portion 110, and placing the product to be compared 300 on the placing portion 110 will not affect the normal assembly of the cover plate 200 and the base 100.

[0060] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 3 , one of the first positioning portion and the second positioning portion includes the first positioning protrusion 131, and the other includes the positioning hole 220. When the screen printing product comparison detection jig is in a detection state, the first positioning protrusion 131 is arranged in the positioning hole 220. The positioning cooperation between the first positioning protrusion 131 and the positioning hole 220 can guarantee the positioning connection of the base 100 and the cover plate 200, can limit the rotation of the cover plate 200 relative to the base 100, guarantee the position of the comparison line 210 fixed, and guarantee the accuracy of the comparison between the comparison line 210 and the product to be compared 300.

[0061] In some embodiments, referring to Figure 2 and Figure 4 , when the first positioning portion includes the first positioning protrusion 131, the base 100 is provided with a mounting hole 120, a pin 130 is detachably arranged in the mounting hole 120, and the part of the pin 130 exposed from the mounting hole 120 forms the first positioning protrusion 131. The pin 130 is detachably connected with the base 100, and the part of the pin 130 exposed from the mounting hole 120 forms the first positioning protrusion 131, which is convenient to process.

[0062] In some embodiments, referring to Figure 1 and Figure 2 , the axial direction of the first positioning protrusion 131 is parallel to the assembly direction of the base 100 and the cover plate 200. The base 100 is placed on the ground, and the assembly direction of the base 100 and the cover plate 200 is from top to bottom along the vertical direction. The axial direction of the first positioning protrusion 131 is parallel to the assembly direction of the base 100 and the cover plate 200, which guarantees the smooth assembly of the cover plate 200 and the base 100.

[0063] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 3When the first positioning portion includes the first positioning protrusion 131, a guide portion 1311 is provided on the first positioning protrusion 131. The guide portion 1311 is conical or hemispherical, and its outer diameter gradually decreases along the assembly direction away from the base 100 and the cover plate 200. The conical or hemispherical guide portion 1311 allows the guide portion 1311 to be more smoothly inserted into the positioning hole 220 when the cover plate 200 is assembled with the base 100, facilitating rapid positioning and assembly of the base 100 and the cover plate 200, thereby improving inspection efficiency.

[0064] In some embodiments, see Figure 2 and Figure 7 The placement portion 110 is provided with a positioning groove 111 for receiving a second positioning protrusion 320 within the product 300 to be compared. The positioning groove 111 can be positioned and engaged with the second positioning protrusion 320 within the product 300 to be compared, thereby restricting the rotation of the product 300 to be compared. When the silk-screen product comparison inspection jig is in the inspection state, the position of the silk-screen pattern 310 on the product 300 to be compared does not change, ensuring the accuracy of the comparison line 210 and the product 300 to be compared.

[0065] In some embodiments, see Figure 2 and Figure 7 The placement portion 110 is cylindrical, with the axial direction of the placement portion 110 parallel to the assembly direction of the base 100 and the cover plate 200. The positioning groove 111 extends parallel to this assembly direction. The base 100 is placed on the ground, with the base 100 and the cover plate 200 assembled vertically from top to bottom. The product to be compared 300 is also assembled vertically from top to bottom with the placement portion 110. The positioning groove 111 extending parallel to the assembly direction of the base 100 and the cover plate 200 makes it easier to remove the product to be compared 300 from the placement seat.

[0066] In some embodiments, see Figure 1 The silk-screen product comparison inspection jig also includes an anti-loss cord, with its ends connected to the base 100 and cover 200, respectively. The middle portion of the cord is spiral-shaped. The cord connecting the base 100 and cover 200 facilitates storage of the silk-screen product comparison inspection jig and prevents the loss of its components.

[0067] The working principle of the screen printing product comparison detection fixture of the embodiment of the application is as follows:

[0068] In the initial state, the silk-screen product comparison inspection fixture is in a state to be inspected. The product to be compared 300 is placed on the placement portion 110 , and the second positioning protrusion 320 in the product to be compared 300 is inserted into the positioning groove 111 .

[0069] The cover 200 is assembled onto the base 100, with the first positioning protrusion 131 inserted into the positioning hole 220. The first foolproof surface 140 and the second foolproof surface 230 are engaged with each other. The silk-screen product comparison inspection fixture is in the inspection state, and the comparison line 210 is compared with the silk-screen pattern 310 on the product to be compared 300 to determine whether the product is qualified. When inspecting the four directional markings on the button cap, the corners of the directional markings are compared with the comparison lines 210. If the corners of the directional markings coincide with the comparison lines 210, the product passes. If the corners of the directional markings do not coincide with the comparison lines 210, the product fails.

[0070] After the comparison is completed, the cover plate 200 is removed from the base 100, and the product to be compared 300 that has been tested is taken away, and the silk-screen product comparison inspection fixture is switched to the state to be tested.
