[0030] See also Figure 1 , Figure 4 , Figure 1 is a schematic diagram of the structure of the battery protection board testing device in the embodiment, Figure 4 Schematic diagram of the structure of the first test mechanism in the embodiment. In this example, a battery protection board test device includes a base plate 1, a first test mechanism 2, a second test mechanism 3, a support mechanism 4 and a support fixture 5, wherein the first test mechanism 2 is arranged on the base plate 1, and a plurality of first test parts 21 are arranged on its top surface, the second test mechanism 3 is mounted on the base plate 1 and is located above the first test mechanism 2, and a plurality of second test parts 31 are arranged on its bottom, and the plurality of second test parts 31 are respectively opposite to the plurality of first test parts 21, and the second test mechanism 3 moves in the vertical direction to make the plurality of second test parts 31 approach or move away from the plurality of first test parts 2 1, the carrying mechanism 4 includes a transverse moving part 41 and a carrying frame 42, the transverse moving part 41 is arranged on both sides of the first test mechanism 2, the carrying frame 42 is located between the first test mechanism 2 and the second test mechanism 3, and both ends are installed on the transverse moving part 41, the transverse moving part 41 can drive the carrying frame 42 to move horizontally, the carrying fixture 5 is carried on the carrying frame 42, and it has a plurality of installation positions 51, the product is carried in the installation position, when the carrying frame 42 is located between the first test part 41 and the second test part 42, the first test part 21 and the second test part 31 are respectively opposite to the installation position 51.

[0031] When in use, the products to be tested are placed in the multiple installation positions 51 of the carrying fixture 5 respectively, and the test fixture 5 loaded with the products to be tested is placed on the carrying frame 42, and then driven by the transverse moving part 41, the carrying frame 42 moves with the carrying fixture 5 to between the first test mechanism 2 and the second test mechanism 3. At this time, the multiple second test parts 31 of the second test mechanism 3 move toward the first test part 21. During the process, the second test mechanism 3 presses the carrying frame 42 downward, so that the first test part 21 and the second test part 31 are connected to the product to be tested. At this time, the product to be tested can be tested by the first test part 21 and the second test part 31. After the test is completed, the second test mechanism 3 is reset, and the carrying frame 42 is also lifted upward and separated from the first test mechanism 2. At this time, the transverse moving part 41 pushes the carrying frame 42 out, and the test fixture 5 loaded with the products to be tested can be taken out and replaced, thereby completing the semi-automatic batch testing of the products. In this way, the product testing efficiency is greatly improved, and the labor intensity of the workers is also greatly reduced.

[0032] See also Figure 2-Figure 3 , review Figure 1 , Figure 2 is a schematic diagram of the structure of the carrying mechanism in the embodiment, Figure 3It is a schematic diagram of the structure of the bearing fixture in the embodiment. Among them, the bearing frame 42 includes a U-shaped bottom frame 421, a floating frame 422 and a plurality of first elastic members 423. The two ends of the U-shaped bottom frame 421 are respectively installed on the transverse displacement part 41, which has a clearance recess 4211, and the clearance recess 4211 faces the top of the first test part 21. A plurality of first elastic members 423 are installed on the U-shaped bottom frame 421 around the clearance recess 4211. The floating frame 422 is carried on the plurality of first elastic members 423, and a connecting window 4221 is opened at the center thereof, and the connecting window 4221 is opposite to the clearance recess 4211. The test fixture 5 is carried on the floating frame 422, and a plurality of mounting positions 51 are all located at the connecting window 4221. Among them, the U-shaped bottom frame 421 is at the same height as the top of the first test part 21. It can be understood that since the U-shaped bottom frame 421 is provided with a clearance recess 4211, when the lateral movement portion 41 moves the supporting frame 42 toward the first test mechanism 2, the first test portion 21 enters into the clearance recess 4211. In this way, not only when the lateral movement portion 41 moves the supporting frame 42 to above the first test portion 21, the top end of the first test portion 21 is closer to the test fixture 5, but also the supporting frame 42 and the first test portion 21 are effectively prevented from interfering and colliding with each other. When working, the second test mechanism 3 moves downward. During the process, the second test part 31 first contacts and connects the product to be tested on the test fixture 5, and presses the test fixture 5 downward, so that the floating frame 422 moves downward and presses down the first elastic member 423, and makes the test fixture 5 close to the first test part 21, so that the top of the first test part 21 is connected to the product to be tested, and completes the product test together with the first test part 21. After the test is completed, the second test mechanism 3 resets upward, the first elastic member 423 loses pressure and rebounds, and the floating frame 422 bounces up, so that the product on the test fixture 5 is disconnected from the first test part 21, and the lateral moving part 41 can push out the carrying frame 42 to replace the test fixture 5 carrying the product to be tested. In this example, the first elastic member 423 is a spring. Among them, the transverse movement part 41 includes two groups of transverse movement drive components 411, and the two groups of transverse movement drive components 411 are respectively located on both sides of the first testing mechanism 2, and one end of each group of transverse movement drive components 411 is fixed on the base plate 1, and the other end extends outside the base plate 1. Each group of transverse movement drive components 411 is composed of a cylinder, a slide rail and a slider.

[0033] Specifically, the floating plate 422 has a plurality of limit through holes 4222. During installation, bolts are used to pass through the limit through holes 4222 from the top of the floating plate 422 and then fixed to the U-shaped bottom frame 421. In this way, an upper limit is generated on the floating plate 422 through the head of the bolt, which can effectively prevent the floating plate 422 from bouncing excessively and falling off when the first elastic member 423 rebounds.

[0034] Specifically, the four corners of the bottom of the floating plate 422 are all provided with sliding shafts 4223, and the four corners of the U-shaped bottom frame 421 are correspondingly provided with sliding sleeves 4212. The sliding shaft 4223 is slidably arranged in the sliding sleeve 4211, which effectively prevents the floating plate 422 from horizontally deviating during the up and down movement of the floating plate 422, causing the first test mechanism 2 and the second test mechanism 3 to be unable to align with the product on the test fixture 5.

[0035] Review Figure 1-Figure 3 Furthermore, the floating frame 422 is also provided with a bearing groove 4224, which is provided on the top surface of the floating frame 422 around the connecting window 4221, and the supporting fixture 5 is supported on the bearing groove 4224. It can be understood that the bearing groove 4224 can not only enable the supporting fixture 5 to be quickly positioned, but also prevent the test fixture from being offset during operation, resulting in the first test mechanism 2 and the second test mechanism 3 being unable to align with the product on the test fixture 5.

[0036] Preferably, the floating plate 422 also has two material taking ports 4225, which are respectively arranged at the two ends of the bearing groove 4224 and penetrate the floating plate 422, and the material taking ports 4225 are connected to the communication window 4221. During operation, the test fixture 5 can be quickly taken in and out through the material taking ports 4225.

[0037] See also Figure 5-Figure 6 , review Figure 1 , Figure 4 , Figure 5 for Figure 4 Schematic diagram of explosion structure. Figure 6 Furthermore, the first testing mechanism 2 further comprises a first support platform 22 , on which a plurality of first wire holes 221 are arranged, and a plurality of first testing units 21 are arranged and installed on the first support platform 22 and are located directly above the first wire holes 221 .

[0038] Each group of the first test section 21 includes a test base frame 211, a mounting frame 212 and a first test head assembly 213. The test base frame 211 is mounted on the first support platform 22 and has a second wire hole 2111 directly opposite to the first wire hole 221. The mounting frame 212 is mounted on the test base frame 211 and is located above the second wire hole 2111. One end of the test head assembly 213 is located in the second wire hole 2111 and fixed to the mounting frame 212, and the other end passes through the mounting frame 212 and is exposed at the top of the mounting frame 212. In this example, the test head assembly 213 is composed of a spring needle module, a circuit board and a PIN needle, wherein the spring needle module and the circuit board are fixed to the bottom of the first support platform 22 and are located in the first wire hole 221, and the PIN needle passes through the first support platform 22 and is exposed at the top of the first support platform 22. In specific implementation, the wiring can be routed through the bottom of the first support platform 22, and connected to the spring pin module of the test head assembly 213 through the first wire hole 221. During operation, when the floating frame 422 is pressed down by the second test mechanism 3, the test fixture 5 gradually approaches the second test part 21, so that the PIN pin of the test head assembly 213 passes through the test fixture 5 and is inserted into the micro connector connected to the product to be tested, thereby realizing the electrical connection between the first test mechanism 2 and the product to be tested. It can be understood that a perforation 511 is provided at the bottom of each mounting position 51 of the test fixture 5 corresponding to the PIN pin of the test head assembly 213. When the product to be tested is placed in the mounting position 51, its micro connector is opposite to the perforation 511, and the PIN pin of the test head 21 can be inserted through the perforation 511 to connect to the product to be tested.

[0039] Preferably, the first test part 21 also includes a plurality of second elastic members 214, which are arranged on the first support platform 22 around the first wire hole 221, and the test bottom frame 211 is installed on the plurality of second elastic members 214, and the two ends of the second elastic member 214 are respectively abutted against the first support platform 22 and the test bottom frame 211. In this example, the second elastic member 214 is also a spring. It can be understood that when the second test mechanism 3 is pressed down to make the floating frame 422 press down the first test part 21, the second elastic member 214 can effectively play its buffering role, and the test fixture 5 and the first test part 21 are impacted and damaged. At the same time, under the reverse force of the second elastic member 214, the PIN pin of the test head assembly 213 can also be more stably connected to the micro connector of the product.

[0040] Preferably, in this example, screws are also used to pass through the test bottom frame 211 and then fixed on the first support platform 22 to perform an upper limit on the test bottom frame 211, which will not be described in detail here.

[0041] Furthermore, the first test part 21 further includes a plurality of third elastic members 215, which are arranged on the test bottom frame 211 around the second wire hole 2111, and the mounting frame 213 is mounted on the plurality of third elastic members 215, and the two ends of the third elastic member 215 are respectively abutted against the mounting frame 213 and the test bottom frame 211. In this example, the third elastic member 215 also adopts a spring, and its function is the same as that of the second elastic member 214. At the same time, in this example, a screw is also adopted to pass through the mounting frame 213 and then fixed on the test bottom frame 211, so as to set the upper limit of the mounting frame 213, which will not be described in detail here.

[0042] Furthermore, the first test part 21 further includes a guide sleeve 216 and a plurality of fourth elastic members 217, the top of which has a guide head 2161, the guide sleeve 216 also has a guide hole 2162, the guide hole 2162 is set through the guide sleeve 216 and the guide head 2161, the plurality of fourth elastic members 217 are arranged on the top of the mounting frame 213 around one end of the test head assembly 213, the guide sleeve 216 is installed on the fourth elastic member 217, and the guide hole 2162 is sleeved on one end of the test head assembly 213, wherein the guide hole 2162 is sleeved outside the PIN pin of the test head assembly 213. Correspondingly, the bottom of the test fixture 5 also has a first guide groove 512 facing the guide sleeve 216, and a second guide groove 513 facing the guide head 2161 is provided in the first guide groove 512, wherein the through hole 511 is provided in the second guide groove 513 and facing the guide hole 2162. In the initial state, the PIN pin of the test head assembly 213 is located in the guide hole 2162. When working, when the second test mechanism 3 is pressed down, the test fixture 5 assembly approaches the test head 213 assembly. During the process, the guide head 2161 abuts against the second guide groove 513, and the guide hole 2162 is opposite to 511. At the same time, the guide sleeve 216 abuts against the first guide groove 512. As the test fixture 5 continues to be pressed down, the guide sleeve 216 is gradually pressed down and compresses the fourth elastic member 217. At this time, the PIN pin of the test head assembly 213 is exposed from the guide hole 2162 to the outside of the guide head 2161 and passes through the through hole 511 to connect to the product to be tested of the carrier fixture 5. In this example, the fourth elastic member 217 is also a spring.

[0043] See also Figure 7-Figure 8 , review Figure 1 , Figure 7 is a schematic diagram of the structure of the second testing mechanism in the embodiment, Figure 8 for Figure 7Enlarged view of part A in the middle. Furthermore, the second test mechanism 3 also includes a lifting part 32, which includes a lifting bracket 321, a lifting drive assembly 322 and a lifting installation box 323. The lifting bracket 321 is mounted on the bottom plate 1, the lifting drive assembly 322 is arranged on the top of the lifting bracket 321, the lifting installation box 323 is located above the first test mechanism 2, and is slidably connected to the lifting bracket 321, the driving end of the lifting drive assembly 322 is transmission-connected to the lifting installation box 323, and the second test part 31 is installed in the lifting installation box 323, one end of which passes through the lifting installation box 323 and is exposed at the bottom of the lifting installation box 323. The lifting bracket 321 includes a bearing plate 3211 and four sliding shafts 3212 standing at the four corners of the bottom plate 1, and the bearing plate 3211 is fixed to the top of the four sliding shafts 3212. In this example, the lifting drive assembly 322 is composed of a cylinder and a push rod. In specific implementation, the lifting installation box 323 can be slidably connected with the sliding shaft 3212 by a sliding sleeve, and the horizontal limit of the lifting installation box 323 can also be achieved by the sliding shaft 3212. That is, when working, the lifting drive assembly 322 drives the lifting installation box 323 to approach the bearing fixture 5, so that the second test part 31 is connected to the product to be tested of the test fixture 5.

[0044] Specifically, in this example, the second test part 31 is composed of multiple power supply probes 311, a connector 312, a temperature sensor 323 and a control board assembly 324, wherein the connector 312 is a miniature connector, that is, when working, the multiple power supply probes 311 contact the product to be tested connected to the test fixture 5 and supply power, the connector 312 is electrically connected to the PIN pin on the product to be tested and conducts data, and the temperature sensor 323 is used to test the temperature of the working environment and feed the temperature back to the external overall control system, which performs temperature compensation to prevent temperature from affecting the test results of the product.

[0045] In summary, in this example, through the cooperation of the first testing mechanism, the second testing mechanism, the supporting mechanism and the supporting fixture, semi-automatic batch testing of battery protection boards is achieved, which greatly improves product testing efficiency and also greatly reduces the labor intensity of workers.
