[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 as well as Figure 2 The embodiment of the utility model provides a testing device 1, including a testing box 11 and a mounting mechanism 12, wherein the mounting mechanism 12 is located in the testing box 11, wherein the testing box 11 can provide a corresponding testing environment, for example, when a high and low temperature test is required for a product 6, the testing box 11 can ensure a high and low temperature environment; the mounting mechanism 12 serves as an installation body for the product 6 to be tested, that is, the product 6 to be tested is installed on the mounting mechanism 12, and the product 6 to be tested is transferred to a designated testing area through the mounting mechanism 12.

[0023] The mounting mechanism 12 includes a mounting frame 13 and a turntable 14 . The mounting frame 13 is a base and is mounted in the test box 11 , while the turntable 14 is mounted on the mounting frame 13 . Specifically, the turntable 14 includes a turntable 141 and a rotating drive member 142. The turntable 141 can be rotatably mounted on the mounting frame 13. The rotating drive member 142 can drive the turntable 141 to rotate around its own axis, that is, the turntable 141's own axis is coaxial with the rotation axis and both are in a vertical direction. A motor can be used for the rotating drive member 142. A mounting structure 15 is arranged on the turntable 141. There are multiple mounting structures 15, and they are all distributed in sequence around the rotation axis of the turntable 141. The product to be tested 6 can be installed on the corresponding mounting structure 15, and a conductive component 16 is arranged on the turntable 141. When the product to be tested 6 is installed on the corresponding mounting structure 15, the product to be tested 6 is electrically connected to the conductive component 16, and power and signal transmission can be provided to the product to be tested 6 through the conductive component 16.

[0024] The test box 11 is provided with a test position and a loading position, both of which are located on the rotation path of the rotating plate 141. At the test position, the product 6 to be tested can be installed on the corresponding mounting structure 15, and the rotating plate 141 is controlled to rotate. Each mounting structure 15 passes through the test position in turn, and then each product 6 to be tested can be installed on each mounting structure 15 in turn. During the rotation process, each product 6 to be tested passes through the test position in turn, and each product 6 to be tested can perform corresponding testing work at the test position in turn. Of course, the loading position can also be used as a unloading position. When the product 6 that has been tested is transferred to the loading position again, it can be detached from the test box 11 at the loading position.

[0025] In the present invention, it is only necessary to load materials into the test box 11 at the loading position, and the station switching work and the detection work are all controlled from the outside of the box, which is not only convenient to operate, but also can accurately control the position of the product 6 in the test box 11, and the detection efficiency is greatly improved. In addition, when the environment in the test box 11 is relatively harsh, such as for high and low temperature detection of the product 6, the influence of the harsh environment in the box on the human body can be avoided, ensuring the safety of detection.

[0026] In one embodiment, the turntable 14 includes a conductive slip ring 147, which is located on the rotation axis of the rotating plate 141, and a plurality of cable passages corresponding to the conductive components 16 are provided on the conductive slip ring 147, and the conductive components 16 are in sliding contact with the corresponding cable passages. In this embodiment, the conductive slip ring 147 adopts a cylindrical structure, and the rotating plate 141 rotates around the conductive slip ring 147, that is, the conductive slip ring 147 does not rotate synchronously with the rotating plate 141; the conductive components 16 correspond to the mounting structure 15 one by one, and correspond to the cable passages on the conductive slip ring 147 one by one, that is, one end of each conductive component 16 is in sliding contact with the corresponding cable passage, and the other end is electrically connected to the product to be tested 6 at the corresponding mounting structure 15, so that the product to be tested 6 is electrically connected to the cable passage through the conductive component 16. The cable path includes an annular electric circuit and an export line 148, wherein the annular electric circuit is arranged along the circumference of the conductive slip ring 147 and is in an annular shape as a whole, and the export line 148 is arranged along the axial direction of the conductive slip ring 147, one end of which is connected to the corresponding annular electric circuit, and the other end extends to the outside of the conductive slip ring 147. During the rotation of the rotating plate 141, the conductive component 16 is always in contact with the corresponding annular electric circuit. A plurality of cable paths are arranged on the conductive slip ring 147, and each annular electric circuit is located on a different circumference of the conductive slip ring 147. During the rotation of the rotating plate 141, each conductive component 16 is always in contact with the corresponding annular electric circuit to achieve electrical connection between the two. In this embodiment, by providing a conductive slip ring 147 of this structure, the connection method between the conductive component 16 and the external circuit can be effectively simplified, and the line winding problem that may occur during the rotation of the rotating plate 141 can be avoided.

[0027] The above embodiment is optimized, specifically, the structure of the conductive component 16 is refined, which includes a cable connector 161 and a conductive cable. The conductive cable is buried in a pre-buried groove 162 provided in the rotating plate 141. The cable connector 161 protrudes from the surface of the rotating plate 141. One end of the conductive cable is connected to the cable connector 161, and the other end is in sliding contact with the corresponding cable channel. In this embodiment, the cable connector 161 can have a jack or a pin to form a plug-in connection with the product 6 to facilitate the electrical connection between the two. The other end of the conductive cable can adopt an electrical contact structure. During the rotation of the rotating plate 141, the electrical contact rotates along the corresponding annular electrical circuit and the two always maintain contact.

[0028] See also Figure 3 In one embodiment, the test device 1 further includes a lifting assembly 17, and the turntable 14 is mounted on the lifting assembly 17. In this embodiment, the lifting assembly 17 is added, and the turntable 14 can be controlled to move in the vertical direction as a whole through the lifting assembly 17 to adjust the vertical position of the product 6 to be tested on the turntable 14. For example, when loading, the turntable 14 can be controlled to be in a lower position. When the loading is completed, the turntable 14 is in a high position, that is, the product 6 to be tested on the turntable 14 is tested at a high position.

[0029] See also Figure 2-Figure 4, the structure of the lifting assembly 17 is detailed, which includes a driving motor 171, a screw 172 and a mounting seat 173. The driving motor 171 is connected to the screw 172 in a transmission manner, that is, the screw 172 can be driven to rotate around itself by the driving motor 171. At least two groups of mounting seats 173 are provided, each mounting seat 173 jointly supports the turntable 14, and one of the mounting seats 173 is threadedly connected to the screw 172, and the screw 172 is vertically installed on the mounting frame 13. In this embodiment, the lifting assembly 17 is driven by the screw 172, and the driving motor 171 drives the screw 172 to rotate, and then the screw 172 drives the mounting seat 173 to move along the length direction of the screw 172, and because the screw 172 is installed vertically, the mounting seat 173 can move in the vertical direction to drive the turntable 14 to move in the vertical direction synchronously, and the screw 172 adopts a T-type screw 172 to achieve overall vertical self-locking. Specifically, the driving motor 171 adopts a high and low temperature servo motor, which is connected to the input shaft end of the right angle reducer 174 through a coupling 175 and is installed on the base plate 131. The output shaft end of the right angle reducer 174 is connected to the screw rod 172 through the coupling 175. The screw rod 172 is installed on the integral bearing seat 178 of the mounting frame 13 through bearings at both ends. Specifically, the integral bearing seat 178 is located on the mounting seat 173, and the nut on the screw rod 172 is connected to the mounting seat 173. The mounting seat 173 is connected to one end of the adapter L plate 176, and the other end of the adapter L plate 176 is connected to the lifting plate 177. The rotating plate 141 can be rotatably installed on the lifting plate 177. When the high and low temperature servo motor rotates, the right angle reducer 174 slows down and transmits, thereby driving the lifting plate 177 to rise or fall. In addition, a sensor is installed on the integral bearing seat 178. When the lifting plate 177 rises or falls to a certain position, the sensor can detect the position of the lifting plate 177, thereby controlling the position accuracy of the rise and fall. The support seat 134 is installed on the base plate 131. One end of the guide shaft 179 is installed in the mounting hole of the support seat 134 and is connected to the base plate 131 at the bottom. The other end is installed in the mounting hole of the connecting plate 180. The linear bearing 181 is installed on the lifting plate 177 and can move up and down within a certain range along the guide shaft 179 to provide a guiding effect for the movement of the lifting plate 177. In order to save more space, the connecting plate 180 is a rod-shaped structure with a guide shaft 179 at both ends. In this way, the guide shaft 179 does not produce a deflection during the guiding process, and the overall structure is stable and reliable. In the preferred embodiment, the mounting frame 13 is a cubic structure as a whole, and the bottom is square, that is, the bottom plate 131 of the mounting frame 13 is square, and the lifting assembly 17 is located at the two corners of the square, so that the lifting assembly 17 does not affect the range of movement of the turntable 14, making the test device 1 more compact and more accommodating.

[0030] The above embodiment is optimized, and a buffer pad 132 is provided on the mounting frame 13, and the buffer pad 132 is located directly below the turntable 14, specifically directly below the lifting plate 177. The buffer pad 132 is made of soft material, which can prevent the lifting plate 177 from contacting the buffer pad 132 when the lifting plate 177 accidentally falls, and the buffer pad 132 plays a buffering role. Usually, a buffer seat 133 is provided on the bottom plate 131 of the mounting frame 13, and there can be multiple buffer seats 133, each of which is discretely distributed and located directly below the lifting plate 177, and each buffer seat 133 is provided with the above buffer pad 132.

[0031] In one embodiment, the mounting structure 15 includes a sliding base plate 151 and a support frame 152. The support frame 152 adopts a frame-type upper and lower layer structure, on which two products to be tested 6 can be installed. The bottom of the support frame 152 is connected to the sliding base plate 151. The sliding base plate 151 has a groove, and the rotating plate 141 has correspondingly distributed protrusions 143. When there are multiple protrusions 143 and multiple sliding base plates 151, there is a one-to-one correspondence between the two. The protrusion 143 is generally in the shape of a long strip, extending from the edge of the rotating plate 141 in the direction of the rotation axis. For example, when the rotating plate 141 is circular, the protrusion 143 is arranged along the radial direction of the rotating plate 141, and the groove of the sliding base plate 151 is slidably matched with the protrusion 143 on the rotating plate 141. A locking block 144 is installed at the tail position of each protrusion 143 on the rotating plate 141, that is, it is located at the protrusion 143 close to the rotation axis, and the locking block 144 and the protrusion 143 are surrounded to form a locking groove. When the sliding base plate 151 moves along the protrusion 143 to the locking block 144, at least a part of the sliding base plate 151 is inserted into the locking groove, thereby realizing the positioning of the sliding base plate 151.

[0032] In a preferred embodiment, a locking cam 145 is further mounted on the rotating plate 141, and the locking cam 145 is rotatably connected to the rotating plate 141 via a cam seat 146, and the rotation path of the locking cam 145 is at least partially located directly above the movement track of the sliding bottom plate 151. In this embodiment, when the sliding bottom plate 151 moves into position along the protrusion 143, the locking cam 145 is rotated, and the locking cam 145 can press the sliding bottom plate 151 against the rotating plate 141. Specifically, the head of each protrusion 143 on the rotating plate 141 is provided with a cam seat 146 and a locking cam 145. The cam seat 146 and the locking cam 145 are rotatably matched, and the locking cam 145 can rotate along the cam seat 146. When locking is required, the locking cam 145 is rotated and the screw thereon is locked. The sliding base plate 151 can be locked until the chamfer on it cooperates with the chamfer on the locking block 144 to prevent the support frame 152 from tipping over as a whole, thereby ensuring the safety of the product 6 during operation. Conversely, when it needs to be released, the screw thereon is loosened and the locking cam 145 is rotated.

[0033] See again Figure 1 as well as Figure 2 The embodiment of the utility model also provides a test system, including a test device 2 and the above-mentioned test device 1, and the test device 2 matches the test position of the test box 11. In the utility model, the test device 1 is in the test box 11, such as a high and low temperature box, and the material is manually loaded to the test device 1 at the loading / unloading unit 3. After the loading is completed, the test box 11 is closed, and the screen display unit 4 or the handle 5 is manually operated to control the automatic lifting or rotation of the test device 1. When the product 6 rotates to the test position, the test device 2 can detect the product 6 at the test position, and realize the switching test of each product 6. After the experiment is completed, the product 6 that has been tested is manually taken out to the loading / unloading unit 3, and the work is completed. The cable of the conductive slip ring 147 is connected to the screen display unit 4 or connected to the test device 2 according to the test requirements. In this way, each product 6 wire can be connected to the external control circuit or power supply circuit through the conductive slip ring 147, and the cable is not entangled during movement, which solves the cable entanglement problem when the overall mechanism moves. Since there are many products to be tested 6, each product to be tested 6 has multiple wires. When the product to be tested 6 is connected to the external circuit through the conductive slip ring 147, the conductive slip ring 147 is also multi-channel. Each conductive slip ring 147 is connected to the screen display unit 4. The screen display unit 4 has a computer board and multiple intermediate relays inside and a touch screen outside. The intermediate relays are controlled by the computer to control the circuit supply and signal transmission of each product to be tested 6. Alternatively, the computer can be replaced by a PLC. Preferably, the computer board has a command input circuit, and the handle 5 is connected to the command input circuit, so that the test device 1 can be controlled by the handle 5.
