Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a clamping and fixing table for circuit board processing. Background Technology

[0002] A clamping and fixing table for circuit board processing is a device used to ensure the stability of circuit boards during manufacturing and assembly. These tables are crucial for ensuring the precision and quality of circuit boards during drilling, soldering, cutting, printing, and testing processes.

[0003] Patent publication number CN212919623U relates to a fixing device for circuit board cutting and processing. It includes a fixing table, two slide rails on the top surface of the fixing table, each slide rail slidably connected to a sliding sleeve, a rotating screw between the sliding sleeves, a pad assembly in the middle of the rotating screw, fixing blocks fixed at each of the four corners of the fixing table, a circuit board fixing bottom block fixed at the top of each fixing block, and a circuit board fixing top block at the top of each circuit board fixing bottom block. While the patent includes circuit board fixing bottom and top blocks to stably fix the circuit board by clamping its four corners, in actual operation, the first bolt needs to be rotated to complete the clamping action. This method cannot quickly complete the clamping, thus increasing the clamping time and potentially reducing the overall efficiency of circuit board processing.

[0004] Therefore, a clamping and fixing table for circuit board processing is needed to shorten the clamping time. Utility Model Content

[0005] To overcome the drawback that in actual operation, the first bolt needs to be rotated to complete the clamping action, which cannot be completed quickly, thus increasing the clamping time and potentially reducing the overall efficiency of circuit board processing, this utility model provides a clamping and fixing table for circuit board processing that shortens the clamping time.

[0006] The technical implementation scheme of this utility model is as follows: a clamping and fixing table for circuit board processing includes a base, a first guide rod, a connecting seat, and a bidirectional screw. The first guide rod is rotatably mounted on the base, and two connecting seats are slidably mounted on the first guide rod. The two connecting seats are jointly provided with a bidirectional screw. The table also includes a placement seat, a second guide rod, a clamping plate, a connecting block, a first elastic element, and a pressing rod. Placement seats are fixedly connected to both the upper and lower sides of the connecting seat. Two second guide rods are fixedly connected to the placement seats. The clamping plate is slidably mounted on the two second guide rods. A connecting block is fixedly connected to the clamping plate and slides inside the placement seat. The first elastic element is sleeved on the second guide rod. The two ends of the first elastic element are respectively connected to the clamping plate and the second guide rod. The pressing rod is slidably mounted on the two placement seats and can contact the connecting block.

[0007] Optionally, it also includes a mounting base, a fitting sleeve, a slide rod, a square rod, a limiting ring, a second elastic element, and a limiting seat. The mounting base is installed on the left side of the base, and the fitting sleeve is fixedly connected to the mounting base. The slide rod is slidably and rotatably mounted on the mounting base. A square groove is opened inside the slide rod. The square rod is fixedly connected to the left end of the first guide rod and engages with the square groove. A limiting ring is fixedly connected to the slide rod, and a second elastic element is sleeved on the slide rod. The two ends of the second elastic element are respectively connected to the mounting base and the limiting ring. A limiting seat is fixedly connected to the left end of the slide rod and engages with the fitting sleeve.

[0008] Optionally, it also includes an exhaust fan and a dust filter, with two exhaust fans mounted on the base and a dust filter embedded in the rear of the exhaust fans.

[0009] Optionally, it also includes protective pads, with protective pads provided on both the placement base and the clamp.

[0010] Optionally, it also includes a support plate and a filter screen. The support plates are fixedly connected to both the left and right sides inside the base, and the filter screen is slidably mounted on both support plates.

[0011] Optionally, it also includes a collection box, which is slidably mounted on the front side of the base.

[0012] Compared with the prior art, the present invention provides a clamping and fixing table for circuit board processing, which has the following beneficial effects: 1. By releasing the squeezing rod, multiple first elastic elements return to their original state, pushing the two clamping plates to move inward simultaneously, thereby clamping the circuit board. This method can quickly complete the clamping action, shorten the clamping time, and improve the efficiency of circuit board processing.

[0013] 2. The second elastic element restores the original shape, pushing the slide bar to the right, thereby causing the limiting seat to re-engage with the fitting sleeve, thus limiting the first guide rod and preventing the first guide rod from rotating during subsequent processing.

[0014] 3. By turning on the exhaust fan, the suction generated by the exhaust fan will draw out the harmful gases produced during the welding process, thereby preventing operators from inhaling these harmful gases and causing discomfort. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: A clamping and fixing table for circuit board processing, please refer to... Figures 1-7The system includes a base 1, a first guide rod 2, a connecting seat 3, and a bidirectional screw 301. The first guide rod 2 is rotatably mounted on the base 1. Two connecting seats 3 are slidably mounted on the first guide rod 2. The two connecting seats 3 are jointly mounted with the bidirectional screw 301. Placement seats 4 are fixedly connected to the upper and lower sides of the connecting seats 3. Two second guide rods 5 are fixedly connected to the placement seats 4. A clamping plate 6 is slidably mounted on the two second guide rods 5. A connecting block 7 is fixedly connected to the clamping plate 6. The connecting block 7 slides inside the placement seat 4. A first elastic element 8 is sleeved on the second guide rod 5. The two ends of the first elastic element 8 are respectively... Connected to the clamping plate 6 and the second guide rod 5, the two placement seats 4 are slidably provided with the pressing rod 9, which can contact the connecting block 7. The placement seat 4 and the clamping plate 6 are both provided with protective pads 18. The protective pads 18 reduce the pressure between the circuit board and the placement seat 4 and the clamping plate 6, thereby avoiding excessive pressure that could damage the circuit board. The left and right sides of the inside of the base 1 are fixedly connected with support plates 21. The two support plates 21 are slidably provided with the filter screen 22. During welding, the filter screen 22 filters the welding waste. The front side of the base 1 is slidably provided with a collection frame 23, which is used to collect the circuit board.

[0025] When the circuit board needs to be processed, first push the pressing rod 9 inward to lift the two connecting plates, so that the two clamping plates 6 move outward and disengage from the corresponding placement seat 4. At this time, multiple first elastic elements 8 are compressed. Then, place the circuit board between the clamping plate 6 and the placement seat 4. After placement, release the pressing rod 9. As the pressing rod 9 is released, multiple first elastic elements 8 return to their original state, pushing the two clamping plates 6 to move inward at the same time, thereby clamping the circuit board. This method can quickly complete the clamping action, shorten the clamping time, and improve the efficiency of circuit board processing. Then, rotate the bidirectional screw 301 to move the connecting seat 3, thereby adjusting the position of the circuit board for subsequent processing. Finally, use welding tools or other appropriate processing equipment to weld or perform other forms of processing on the circuit board.

[0026] Example 2: Based on Example 1, please refer to... Figure 2 , Figure 3 , Figure 5 and Figure 6 A mounting base 10 is bolted to the left side of the base 1. A fitting sleeve 11 is fixedly connected to the mounting base 10. A sliding rod 12 is slidably and rotatably mounted on the mounting base 10. A square groove 13 is opened inside the sliding rod 12. A square rod 14 is fixedly connected to the left end of the first guide rod 2. The square rod 14 is engaged with the square groove 13. A limit ring 15 is fixedly connected to the sliding rod 12. A second elastic element 16 is sleeved on the sliding rod 12. The two ends of the second elastic element 16 are connected to the mounting base 10 and the limit ring 15, respectively. A limit seat 17 is fixedly connected to the left end of the sliding rod 12. The limit seat 17 is engaged with the fitting sleeve 11.

[0027] After the circuit board on the upper part of the connector 3 is processed, pull the slide bar 12 to the left to disengage the limiting seat 17 from the fitting sleeve 11. At this time, the second elastic element 16 is compressed. Then, rotate the slide bar 12 to drive the square rod 14 and the first guide rod 2 to rotate, thereby adjusting the connector 3 so that the circuit board of the lower connector 3 rotates to the upper position. After the adjustment is completed, release the slide bar 12, the second elastic element 16 returns to its original state, and pushes the slide bar 12 to the right, thereby re-engaging the limiting seat 17 with the fitting sleeve 11, thus limiting the first guide rod 2 and preventing the first guide rod 2 from rotating during subsequent processing.

[0028] Please see Figure 1 and Figure 7 Two exhaust fans 19 are installed on the base 1 by means of bolt connection, and a dustproof net 20 is embedded on the rear side of the exhaust fan 19.

[0029] When performing welding, the exhaust fan 19 is turned on. The suction generated by the exhaust fan 19 will draw out the harmful gases produced during the welding process, thereby preventing the operator from inhaling these harmful gases and causing discomfort.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
