[0001] The utility model relates to a fixture and a testing device. Background Art

[0002] At present, in manufacturing factories, the work of plugging and unplugging Type-C test lines has been replaced by automated equipment. In order to prevent products from being scratched during the process, plastic protective cases are usually used to cover the products. This causes errors due to the protective cases when the products are undergoing automated tests.

[0003] In the prior art, in order to align the test line with the test hole in the device, the test line is covered with rubber, and the rubber is squeezed during the test to absorb the errors around the test line to achieve the alignment purpose. However, due to the existence of the plastic protective case, its excessive errors prevent the device test line from aligning with the test hole as expected for correct testing, causing a major bottleneck in automated testing and being less convenient than manual testing.

[0004] Therefore, the utility model provides a solution. Summary of the Utility Model

[0005] The utility model relates to a fixture, including a base, a body, a telescopic member, and a guiding block. The base includes a groove. The body is movably limited in the groove. The body has a side surface and an assembly groove communicating with the side surface.

[0068] 1.1 Base and Body

[0069] In some embodiments, the body 120 further has a second side surface 122, a third side surface 123, and a fourth side surface 124. The first side surface 121 and the third side surface 123 are two relatively parallel surfaces. The second side surface 122 and the fourth side surface 124 are two relatively parallel surfaces. The first side surface 121 and the second side surface 122 intersect perpendicularly, and the third side surface 123 and the fourth side surface 124 intersect perpendicularly.

[0070] In some embodiments, the base 110 has a through hole 1121 on the side edge facing the second side surface 122 of the body 120, and another through hole 1121 on the side edge facing the fourth side surface 124 of the body 120.

[0071] In some embodiments, the body 120 further has a shaft hole 126 extending from the first side surface 121 along the first axial direction A1 through the body 120 to the third side surface 123. In Figure 2 Among them, there is more than one shaft hole 126 on the first side surface 121. The structures of these shaft holes 126 are the same, only located at different positions on the first side surface 121. In some embodiments, these shaft holes 126 on the first side surface 121 can be arranged in parallel, but the present invention is not limited thereto.

[0072] In some embodiments, the body 120 has a recess 127 on the second side surface 122. In some embodiments, the recess 127 can be cylindrical, and it has the same axis as the through hole 1121 of the base 110 in the second axial direction A2, but the present invention is not limited thereto. The body 120 further has another cylindrical recess 127 (not shown in the figure) on the fourth side surface 124, which has the same axis as the other through hole 1121 of the base 110 in the second axial direction A2.

[0073] In some embodiments, the body 120 further has a top surface 128 that is away from the base 110 and connected to the first side surface 121.

In some embodiments, the assembly groove 125 is configured to place the test line 160. In some embodiments, the test line 160 can be a Type-C wire, or a connection wire, charging wire, etc. of other electronic devices, but the present utility model is not limited thereto.

[0074] 1.2 Telescopic member

[0075] In some embodiments, the telescopic member 130 includes a linear bearing 131, a guide rod 132, and a spring 133. Figure 1 And Figure 2 In, the number of the telescopic members 130 is two, and the structures and configurations of the two groups of telescopic members 130 are the same, only located at different positions on the first side surface 121. Therefore, one of the groups is used as a representative for description herein.

[0076] In some embodiments, the linear bearing 131 is disposed in the shaft hole 126, and cooperates with the guide rod 132 and the spring 133 to perform a linear compression or release movement along the first axial direction A1. The alignment block 140 is connected to one end of the guide rod 132. The guide rod 132 passes through the linear bearing 131 and is configured to slide relative to the linear bearing 131 along the first axial direction A1, and cooperate with the linear bearing 131 to compress or release the spring 133. The spring 133 is sleeved on the guide rod 132 and is configured to be compressed between the linear bearing 131 and the alignment block 140. In some embodiments, the guide rod 132 is a chrome-plated rod, but the present utility model is not limited thereto. The present utility model aligns the alignment block 140 by compressing and releasing the telescopic member 130.

[0077] 1.3 Alignment block

[0078] Please refer to Figure 3 , Figure 3 is a top view of the alignment block 140 in a plane formed by the first axial direction A1 and the second axial direction A2 according to an embodiment of the present utility model.

[0079] In some embodiments, the alignment block 140 includes a convex block 141 having a chamfer θ. Figure 3 In, the convex block 141 has a wedge-shaped top 1411 that extends along the first axial direction A1. The chamfer θ is an angle formed by the inclined surface of the wedge-shaped top 1411 with respect to the first axial direction A1. In some embodiments, the chamfer θ is 35 to 40 degrees, but the present utility model is not limited thereto.

[0080] 1.4 Upper cover

[0081] In Figure 1and Figure 2 In Figure 2 , the fixture 100 further includes an upper cover 150 and a fixing member 152. The upper cover 150 is connected to the main body 120 and covers the portion of the assembly opening 1251 located on the top surface 128. In some embodiments, the upper cover 150 further has a slot 151. In Figure 1 and Figure 2 In Figure 1 and Figure 2 , both the upper cover 150 and the fixing member 152 have two slots 151, but the present invention is not limited thereto. The upper cover 150 is connected to the main body 120 by the fixing member 152 passing through the slot 151 respectively, and can slide along the second axial direction A2 through the slot 151 to fix the test line 160. In some embodiments, the fixing member 152 is a quick-release screw, which can be easily disassembled and assembled to facilitate the replacement of the test line 160, but the present invention is not limited thereto.

[0082] 1.5 Stopper

[0083] In Figure 1 and Figure 2 In Figure 1 and Figure 2 , the fixture 100 further includes a stopper 170. The stopper 170 is connected to the third side surface 123 of the main body 120, faces the shaft hole 126 in the first axial direction A1, and is configured to fix the guiding rod 132 so that it is not disengaged from the linear bearing 131 by the spring 133.

[0084] In some embodiments, although there is a linear bearing 131 in the telescopic member 130 to limit the linear sliding of the guiding rod 132 along the first axial direction A1, when the guiding rod 132 slides along the first axial direction A1 towards the third side surface 123 during the compression of the compression spring 133, the linear bearing 131 will relatively gradually move towards the end of the guiding rod 132 close to the first side surface 121, resulting in the problem of shaking at the end of the guiding rod 132 close to the third side surface 123. Therefore, a stopper 170 is provided on the third side surface 123 to maintain the guiding rod 132 sliding on the same axis.

[0085] 1.6 Buffer

[0086] In Figure 1 and Figure 2 In Figure 1 and Figure 2 , the fixture 100 further includes a buffer 180. The buffer 180 is at least partially located in the groove 111 of the base 110, and the base 110 is connected to the main body 120 via the buffer 180.

[0087] Please refer to Figure 1 and Figure 4, the buffer member 180 includes a ball screw 181 and a nut 182. In some embodiments, the ball screw 181 has a ball 1811 and a spring 1812. Due to the special structure of the ball screw 181, in actual use, even if the ball 1811 of the ball screw 181 has abutted against the target object, there is still a space in the ball screw 181 for the spring 1812 to be compressed, so that there is still some elasticity for the ball screw 181 to move relative to the target object.

[0088] 1.7 Buffer space

[0089] Please refer to Figure 5A and Figure 5B , Figure 5A is a top view of the jig 100 according to an embodiment of the present invention in the plane formed by the first axial direction A1 and the second axial direction A2. Figure 5B Then it is according to Figure 5A The sectional view of the A-A' section in. In Figure 5A and Figure 5B , at the side of the body 120 in the direction of the second side surface 122, the buffer member 180 is connected to the base 110 and the body 120 through the through hole 1121 and the recess 127. The jig 100 is connected in the same way at the side in the direction of the fourth side surface 124 of the body 120, which will not be elaborated here.

[0090] In Figure 5A , at the parts of the second side surface 122, the third side surface 123 and the fourth side surface 124 of the body 120 opposite to the groove 111, there are buffer spaces S1, S2 and S3 respectively. These buffer spaces have a gap of about 1 mm, or have a gap of about 0.5 to about 1 mm, but the present invention is not limited thereto. Through the buffer space between the base 110 and the body 120, when the jig 100 is aligned, an error range of 0.5 to 1 mm can be effectively absorbed.

[0091] Please refer to Figure 5B , taking the structure of the A-A' section in Figure 5A as an example, the buffer member 180 passes through the through hole 1121 and is partially located in the space of the recess 127, and is not completely fastened, so that there is a buffer space S1 between the base 110 and the body 120. In this case, when the jig 100 is aligned, the position of the body 120 in the base 110 can be appropriately fine-tuned as needed, so as to achieve the effect of absorbing errors.

[0092] In some embodiments, the base 110, the body 120, and the upper cover 150 are made of aluminum alloy, but the present utility model is not limited thereto. In some embodiments, the alignment block 140 is made of polyoxymethylene (POM), but the present utility model is not limited thereto. In some embodiments, the stop block 170 can be metal or plastic, but the present utility model is not limited thereto.

[0093] 2. Testing Equipment

[0094] Please refer to Figure 6A and Figure 6B , Figure 6A and Figure 6B are schematic diagrams of a testing device 200 according to an embodiment of the present utility model. In Figure 6A and Figure 6B , the testing device 200 includes the fixture 100 and the testing platform 190 as described above. The testing platform 190 includes a guiding hole 191 and a testing hole 192.

[0095] In some embodiments, the product to be tested is placed on the testing platform 190. In Figure 6A and Figure 6B , the testing hole 192 can be regarded as the connection jack of the product to be tested itself.

[0096] Figure 6A is a schematic diagram of the alignment stage of the testing device 200 (please refer to the following description in conjunction with Figure 1 and Figure 2 ). When performing the test of the product, the test line 160 is placed in the assembly groove 125, and the fixture 100 is pushed towards the testing platform 190 by a power source (not shown in the figure), so that the convex block 141 of the alignment block 140 first contacts the guiding hole 191 of the testing platform 190, and alignment is performed through the wedge-shaped top 1411 at the front end of the convex block 141. At this time, since the wedge-shaped top 1411 at the front end of the convex block 141 has a chamfer θ, the guiding hole 191 can be aligned more precisely. After the alignment block 140 is aligned with the guiding hole 191, the power source continuously outputs power to compress the telescopic member 130, so that the fixture 100 approaches the testing platform 190. At the same time, since there is a buffer space between the base 110 and the body 120, the body 120 floats and adjusts within the base 110 to absorb the error generated by the protective shell of the product.

[0097] Figure 6B is a schematic diagram of the stage when the testing device 200 completes the alignment action (please refer to the following description in conjunction with Figure 1 ). In Figure 6B , the power source has pushed the fixture 100 against the testing platform 190, and the test line 160 has accurately entered the testing hole 192.

[0098] In some embodiments, the power source for moving the jig 100 towards the test platform 190 can be a locking cylinder or a motor, or any power source capable of performing this action, but the present utility model is not limited thereto.

[0099] In some embodiments, the test holes 192 are input / output (I / O) holes, and different connection line tests can be performed as needed. For example, a type-C connection test or a USB connection test can be performed, but the present utility model is not limited thereto.

[0100] In some embodiments, the jig 100 may include more than one assembly slot 125. Multiple assembly slots can be amplified as needed and multiple test lines can be loaded to simultaneously test multiple products, but the present utility model is not limited thereto.

[0101] In some embodiments, the alignment block 140 can be a magnetic element that guides and aligns by magnetic attraction, but the present utility model is not limited thereto.

[0102] 3. Examples and Comparative Examples

[0103] The following Table 1 shows the test results of the present utility model for examples and comparative examples. The example is to perform an alignment test using the jig of an embodiment of the present utility model, and the comparative example is to perform an alignment test using a jig other than the present utility model. The jig used in the comparative example has a base including a groove. After the test line is coated with rubber, it is placed in the groove of the base, and a power source is used to push the jig towards the test platform so that the test line is inserted into the test hole, and the rubber around the test line is used to absorb errors.

[0104] [Table 1]

[0105]

[0106] As can be seen from Table 1, compared with the jig used in the comparative example, the jig of an embodiment of the present utility model can absorb an error range of 2.5 to 5 times during alignment due to the use of the alignment block for guiding function and the presence of a buffer space between the body and the base, and has better alignment ability.

[0107] In summary, the jig of an embodiment of the present utility model can increase the alignment rate during automated testing through the alignment block for position guiding, has a guiding function, and can absorb the error range generated by the product protection shell through the buffer space between the base and the body, enabling the test line to accurately enter the test hole and greatly improving the efficiency of automated testing.
