The cross-sections of the rectangular through grooves 252 and the positioning rods 2510 are both rectangular. An inclined cone block 2511 is connected to the end of each positioning rod 2510. The two inclined cone blocks 2511 are located on both sides within the clamping groove 251. One side of the inclined cone block 2511 is a cone surface, which pushes the bottom of the PCB board to fit tightly against the bottom of the clamping groove 251, keeping the PCB board in a horizontal state when applying glue.

[0068] The positioning rod 2510 has an adjustable groove inside. The end of the positioning rod 2510 is rotatably connected to a threaded rod. The end of the connecting rod 259 slides in the adjustable groove. The threaded rod is threadedly connected to the connecting rod 259. The surface of the positioning rod 2510 is provided with a scale. The end of the connecting rod 259 is connected to a pointer. The pointer is located on the positioning rod 2510. The operator can manually adjust the distance between the two positioning rods 2510 according to the size of the PCB board to be clamped, so that PCB boards of different sizes can be placed in the clamping groove 251 and all of them can be clamped and positioned.

[0069] In use, the PCB board is placed in the clamping slot 251. The drive slider 212 then begins to move, causing the rotating rod 254 and L-shaped rod 255 within the slider 212 to move within the straight rail slot 216 and the parallel rail slot 214, respectively. At this point, the rotating rod 254 and L-shaped rod 255 are horizontal. The rotating rod 254 moves forward along the straight rail slot 216, causing the end of the L-shaped rod 255 to move along the parallel rail slot 214 into the straight rail slot 216, until the rotating rod 254 and L-shaped rod 255 are vertical. This causes the rotating block 253 to rotate 90 degrees around the rotating rod 254. Simultaneously, the rotating rod 254 and L-shaped rod 255 move forward within the straight rail slot 216. The rotating block 253 causes the rotating plate 256 and the arc-shaped slot 257 to rotate. The arc-shaped slot 257 pulls the sliding guide rod 258, and the two positioning rods 2510 move towards the center within the rectangular through slot 252. As the components move closer together, the two positioning rods 2510 move in opposite directions to separate. The inclined cone blocks 2511 at the ends of the two positioning rods 2510 press the PCB board tightly against the bottom of the clamping groove 251 and fix it in the middle of the clamping groove 251. This facilitates the automatic clamping and fixing of the PCB board after the operator places it in. Similarly, when the rotating block 253 moves to the separation area, the L-shaped rod 255 enters the reverse rail groove 215 of the separation area under the action of the torsion spring 2512, causing the rotating block 253 to rotate around the rotating rod 254 and causing the rotating plate 256 to rotate. This causes the two positioning rods 2510 and the clamping plate 263 to separate in the clamping groove 251. At this time, the inclined cone block 2511 and the PCB board automatically separate, which is convenient for the operator to pick up the PCB board after gluing for the next step of processing.

[0070] Example 3, referring to Figure 11 and Figure 12 This is the third embodiment of the present invention, which differs from the previous embodiment in that it includes an extrusion member 26.

[0071] Specifically, an extrusion member 26 is provided inside the inclined cone block 2511.

[0072] Furthermore, an extrusion member 26 is installed inside the inclined cone block 2511;

[0073] Specifically, the extrusion part 26 includes a built-in through groove 261, an inclined cone block 2511 with a built-in through groove 261, a third spring 262 is provided in the built-in through groove 261, a clamping plate 263 is provided at the end of the third spring 262, a sliding rod 264 and a round rod 265 are provided at the end of the clamping plate 263, a blocking rod 266 is provided in the built-in through groove 261, a round groove 267 is provided on the surface of the blocking rod 266, a fourth spring 268 is provided between the blocking rod 266 and the built-in through groove 261, and an inclined groove 269 is provided in the clamping groove 251.

[0074] Furthermore, the extrusion part 26 includes a built-in through groove 261. The built-in through groove 261 is opened in the inclined cone block 2511. A third spring 262 is connected to the middle of the built-in through groove 261. One end of the third spring 262 is connected to a clamping plate 263. The clamping plate 263 is located in the clamping groove 251. The two clamping plates 263 are placed symmetrically on the axis in the clamping groove 251. The two clamping plates 263 contact the upper end or the lower end of the PCB board respectively, clamping and positioning the PCB board in the middle of the two inclined cone blocks 2511.

[0075] The end of the clamping plate 263 is connected to a sliding rod 264 and a round rod 265. The end of the sliding rod 264 is located inside the clamping plate 263 and contacts the inner wall of the clamping groove 251. The round rod 265 is located inside the built-in through groove 261. The blocking rod 266 is horizontal in the built-in through groove 261, and the end of the blocking rod 266 passes through the inclined cone block 2511 and is located inside the clamping groove 251. A fourth spring 268 is connected between the blocking rod 266 and the built-in through groove 261. A round groove 267 is opened on the surface of the blocking rod 266. The inner diameter of the round groove 267 is the same as the diameter of the round rod 265. The end of the round rod 265 slides on the surface of the blocking rod 266.

[0076] When the two inclined cone blocks 2511 are attached to the inner walls of the clamping groove 251 on both sides, the third spring 262 has the maximum extension length. The clamping plate 263 is located at the end of the built-in through groove 261 on the inclined cone block 2511. The sliding rod 264 is in contact with the top of the inclined groove 269 of the clamping groove 251. When both inclined cone blocks 2511 are in contact with the PCB board, the compression blocking rod 266 moves laterally in the built-in through groove 261, causing the round rod 265 to enter the round groove 267 under the action of the third spring 262 and continue to move in the built-in through groove 261. Both clamping plates 263 move laterally. Similarly, when the positioning rod 2510 drives the two inclined cone blocks 2511 to separate, and the inclined cone blocks 2511 gradually attach to the inner wall of the clamping groove 251, the sliding rod 264 at the end of the clamping plate 263 slides and presses against the inclined groove 269, causing the sliding rod 264 to pull the blocking rod 266 from the middle to the end of the inclined cone block 2511 until the round rod 265 separates from the round groove 267, and the blocking rod 266, under the action of the fourth spring 268, protrudes again from the inclined cone block 2511 into the clamping groove 251;

[0077] During use, the end of the L-shaped rod 255 moves from the guide groove 214 into the straight groove, causing the two inclined cone blocks 2511 to simultaneously contact and press against both sides of the PCB board. At this time, the blocking rod 266 enters the built-in through groove 261, and the round rod 265, under the action of the third spring 262, enters the round groove 267 on the blocking rod 266. The two clamping plates 263 move simultaneously towards the middle of the inclined cone blocks 2511 until the two clamping plates 263 clamp the PCB board in the middle of the two inclined cone blocks 2511. This makes the electronic components on the PCB board have high stability when applying glue, which is beneficial for the PCB board to maintain high-frequency low-amplitude vibration when the slider 212 moves to the glue-pouring area, thus improving the stability of the PCB board during glue-pouring.
