The first conveyor belt 620 is movably connected to the first drive wheel 650 and the first driven wheel 660. In this embodiment, both the first drive member 500 and the second drive member 640 are motors.

[0028] According to some embodiments of the present invention, the support 610 is provided with a blocking member 611 and a check member 612 along the X-axis direction. The upper surface of the blocking member 611 is inclined upward along the feeding and discharging directions of the X-axis, so that during the feeding process, the carrier plate 800 can enter through the inclined upper surface of the blocking member 610.

The upper end of the check member 612 is provided with a roller to reduce the friction after the carrier plate 800 collides and rubs with the check member 612 during the movement.

[0029] According to some embodiments of the present invention, the bracket 610 is provided with side guards 613 on both sides along the Y-axis direction. The side guards 613 are located on the upper side of the first conveyor belt 620. The two side guards 613 are used to restrict the carrier plate 800 on the first conveyor belt 620. The check member 612, the side guards 613 and the blocking member 611 together restrict the position of the carrier plate 800. The side guards 613 can prevent the carrier plate 800 from coming out of the area of ​​the first conveyor belt 620 and can also play a lateral positioning role for the carrier plate 800.

[0030] According to some embodiments of the present invention, multiple test fixtures 200 are provided, and the multiple test fixtures 200 are arranged sequentially from top to bottom in the frame 100. By setting multiple test fixtures 200, multiple workpieces can be tested simultaneously, thereby improving testing efficiency. Correspondingly, a support column 410 is provided on the first base plate 400, and a second base plate 420 is provided at the upper end of the support column 410. A first driving member 500 and a conveying assembly 600 are provided on the second base plate 420. That is, in this embodiment, at least two sets of conveying assemblies 600 with first driving members 500 are provided, which can simultaneously load and unload two test fixtures 200, or one conveying assembly 600 can load the test fixture 200 while the other conveying assembly 600 can retrieve the tested workpiece from the test fixture 200.

[0031] According to some embodiments of the present invention, a third base plate 700 is also included. The third base plate 700 is movably disposed on the support frame 300 and located below the first base plate 400. A conveying assembly 600 is provided on the third base plate 700. It is understood that the conveying assembly 600 at this location is not connected to the first driving member 500. That is, the conveying assembly 600 at this location is only used to obtain the tested workpiece from the test fixture 200. In actual application, different numbers of conveying assemblies 600 and first driving members 500 can be set according to actual usage needs.

[0032] According to some embodiments of the present invention, the support frame 300 is provided with a lifting mechanism 310 and a slide rail 320. The lifting mechanism 310 is used to drive the first base plate 400 and the third base plate 700 to move up and down along the slide rail 320. The lifting mechanism 310 can be a motor or a cylinder. In this embodiment, the lifting assembly 310 uses a motor and a belt to drive the lifting of the first base plate 400. The first base plate 400 is fixed to the belt by a fixing block. The third base plate 700 is separately provided with a cylinder for lifting. The first base plate 400 and the third base plate 700 are both connected to the slide rail 320 by a slider. The slide rail 320 plays a role in orientation and reducing friction.

[0033] According to some embodiments of the present invention, a fourth base plate 210 is also included, which is disposed on the frame 100. The pressure plate module 230, the belt conveyor mechanism 250 and the needle plate module 220 are all disposed on the fourth base plate 210.

[0034] According to some embodiments of the present invention, the belt conveyor mechanism 250 includes: a mounting frame 251 disposed on a fourth base plate 210; a third drive member disposed on one side of the mounting frame 251; a second conveying belt 253 movably disposed on both sides of the mounting frame 251 along the X-axis direction for conveying a carrier plate 800; and two second drive wheels 254 movably disposed on both sides of the mounting frame 251 along the X-axis direction and connected by a rotating shaft, wherein each drive wheel 254 corresponds to one of the second conveying belts 253, and the drive wheels 254 are connected to the third drive member for conveying materials. The output end is connected; multiple second driven wheels 255 are movably mounted on the mounting frame 251. Each driving wheel 254 has at least one driven wheel 255 on both sides along the Y-axis. The second driven wheels 255 are used to support the second conveyor belt 253 and to change the direction of the second conveyor belt 253. The carrier plate 800 is conveyed by using the second conveyor belt 253. The top and sides of the second conveyor belt 253 provide friction to the carrier plate 800 for conveying. The overall structure is compact and can be installed in test fixtures 200 with compact space structures.

[0035] According to some embodiments of the present invention, the mounting bracket 251 is further provided with a guide plate 257, and the guide plate 257 is provided with a guide groove. The lower end of the second conveyor belt 253 is slidably disposed in the guide groove. The guide groove guides the movement of the second conveyor belt 253 and supports the second conveyor belt 253, so that the second conveyor belt 253 fully contacts the carrier plate 800 and provides driving force for the carrier plate 800.

[0036] According to some embodiments of the present invention, a plurality of tensioning wheels 258 are also included. The tensioning wheels 258 are movably disposed on the mounting frame 251. The tensioning wheels 258 can tighten the second conveyor belt 253 so that it can fully contact the carrier plate 800, avoiding the situation where it cannot effectively provide sufficient friction to the carrier plate 800 after slack, thus failing to drive the carrier plate 800.

[0037] According to some embodiments of the present invention, the needle plate module 220 includes a needle carrier plate 221 and a support block 222. The needle carrier plate 221 is disposed on the support block 222, and the support block 222 is disposed on the fourth base plate 210. A limiting block 223 is provided on the needle carrier plate 221. The limiting block 223 is used to restrict the movement of the carrier plate 800 in the Y-axis direction. When the conveying component 600 inputs the workpiece to be tested into the test fixture 200, the limiting block 223 can play a role in limiting and positioning, saving the time of manual positioning, and also preventing the workpiece from falling out of the test area.

[0038] According to some embodiments of the present invention, a guide rail 211 is provided on the fourth base plate 210 along the X-axis direction, and the lower end of the support block 222 is slidably connected to the guide rail 211 by a slider. By slidably connecting the support block 222 to the guide rail 211 of the fourth base plate 210, the needle plate module 220 can be quickly replaced according to different testing requirements, thereby increasing the versatility of the test fixture 200.

[0039] According to some embodiments of the present invention, the pressure plate module 230 includes an upper pressure plate 231 and two lower pressure plates 232. The two lower pressure plates 232 are respectively connected to the lower part of the upper pressure plate 231. The two sides of the upper pressure plate 231 are connected to the output ends of the lifting cylinder 240. The lower pressure plates 232 are provided with a test module 233. In this embodiment, there are two lower pressure plates 232, which can simultaneously test two workpieces on the carrier plate 800. In some other embodiments, multiple lower pressure plates 232 can be arranged according to actual needs.

[0040] According to some embodiments of the present invention, the upper end face of the upper pressure plate 231 is further provided with several reinforcing ribs to enhance the structural strength of the upper pressure plate itself.

[0041] According to some embodiments of the present invention, the test fixture 200 further includes a housing 260, which is disposed on the fourth base plate 210 and has a plurality of heat dissipation holes 261.

[0042] The testing process of the above SMT testing equipment is as follows: The workpiece to be tested is input onto the conveying assembly 600 via a conveyor belt. The lifting mechanism 310 drives the first base plate 400 to a set height, that is, the first conveyor belt 620 in the conveying assembly 600 is level with the second conveyor belt 253 in the test fixture 200. At this time, the first driving member 500 drives the conveying assembly 600 to rotate towards the test fixture 200, that is, in the Y-axis direction, so that the first conveyor belt 620 and the second conveyor belt 253 are aligned. The second driving member 640 drives the first drive wheel 650 to rotate, so that the first conveyor belt 620 conveys the workpiece to be tested onto the second conveyor belt 253, and the third driving member drives the second drive wheel 253. 4. The second conveyor belt 253 transports the workpiece to be tested to the test position in the test fixture 200 for testing. After the test is completed, the third drive unit drives the second conveyor belt 253 to transport the tested workpiece to the first conveyor belt 620. The first drive unit 500 drives the conveyor assembly 600 to rotate to face the X-axis direction. The lifting mechanism 310 drives the first floor 400 and the conveyor assembly 600 to be flush with the conveyor belt. Then, the second drive unit 640 drives the first conveyor belt 620 to return the tested workpiece to the conveyor belt for discharge. It can be understood that the feeding conveyor belt and the discharge conveyor belt are respectively located on both sides of the X-axis direction of the test equipment.

[0043] The beneficial effects of this invention are as follows: 1. The first driving component 500 drives the conveying assembly 600 to rotate towards the conveyor belt, so that the workpiece to be tested from the conveyor belt can be conveyed onto the conveying assembly 600, or the workpiece that has completed testing on the conveying assembly 600 can be returned to the conveyor belt. The first driving component 500 drives the conveying assembly 600 loaded with workpieces to rotate towards the test fixture 200, so that the conveying assembly 600 can convey the workpiece to be tested into the test fixture 200, or retrieve the workpiece that has completed testing from the test fixture 200. The whole process from loading to testing to unloading is automatic, improving testing efficiency. Moreover, no repositioning is required during the whole process, the space occupied is small, the structure is simple, and the loading and unloading efficiency is high.

[0044] 2. The carrier plate 800 is conveyed by using a second conveyor belt 253. The top and sides of the second conveyor belt 253 provide friction to the carrier plate 800 for conveying. The overall structure is compact and can be installed in test fixtures 200 with compact space. At the same time, since each angle of the second conveyor belt 253 can provide friction to the carrier plate 800, it is not limited to using only the top of the second conveyor belt 253 for transportation, making the installation method of the belt conveyor mechanism 250 more diverse.
