Description

Technical Field

[0001] The present invention relates to the technical field of display accessories, and particularly to a PCB board backrest tooling for LCD display assembly. Background Art

[0002] A PCB board is a printed circuit board, which is the circuit board of an LCD display. The PCB board is bonded to the FPC wiring on the liquid crystal panel through a bonding machine to form an integrated body. The tooling for placing the PCB board in the FOB bonding machine is a backrest. In the traditional PCB board backrest tooling, there is a defect of fixed size. Different-sized PCB boards require different-sized backrest toolings. Therefore, different-sized backrest toolings need to be prepared during processing. Different-sized backrest toolings are difficult to be compatible, increasing the cost loss, and lacking the flexibility of deployment, with too low universality. Therefore, we propose a PCB board backrest tooling for LCD display assembly. Summary of the Invention

The two connecting pieces rotate independently, and when splicing, the two connecting pieces respectively face the splicing seats on both sides; through holes are provided in the middle of the connecting pieces;

[0012] The splicing block in the splicing seat is provided with a splicing fixing bolt. Rotate the connecting piece in the mounting seat into the splicing block of the splicing seat, and then the splicing fixing bolt is inserted downward to fix the connecting piece. The mounting seat and the splicing seat are fixed together through the connection between the connecting piece and the splicing fixing bolt to complete the width expansion of the mounting seat;

[0013] One end of the second arc block close to the first arc block is provided with a connecting head, a connecting groove is opened at one end of the first arc block close to the second arc block, and a connecting head is provided at one end of the first arc block away from the second arc block; there are two types of flat blocks.

[0014] The length and width expansion of the mounting seat corresponds to the length and width expansion of the support seat; the flat block, the first arc block, and the second arc block on the mounting seat form a main support seat, and the flat block, the first arc block, and the second arc block on the splicing seat form a side support seat; lateral plates are installed on both sides of the flat block, the first arc block, and the second arc block of the main support seat, and lateral grooves are opened on one side of the flat block, the first arc block, and the second arc block of the side support seat close to the main support seat. The main support seat and the side support seat are fixed by docking the lateral plates and the lateral grooves;

[0015] One side of the supporting seat is provided with an electrostatic eliminator, which is composed of a mounting panel and an ion bar. Three mounting blocks are arranged on the side of the mounting panel close to the supporting seat; a panel groove is formed on the side of the side plate close to the electrostatic eliminator, and the mounting blocks on the electrostatic eliminator are inserted into the panel groove; the electrostatic eliminator is fixed on any three adjacent blocks of the supporting seat.

[0016] Preferably, a locking bolt is screwed on the top of the connecting block, and when the bottom of the locking bolt faces downwards, it abuts against the top of the telescopic block, and the telescopic block is fixed by the friction between the locking bolt and the telescopic block.

[0017] Preferably, one end of the plug-in block is provided with an extending plate extending outwards. Through holes are symmetrically formed in the extending plate, and a through hole for fixing the plug-in block is formed in the middle of the extending plate. A fixing bolt for the plug-in block is screwed in the through hole for fixing the plug-in block. After adjacent plug-in blocks are engaged with each other, the fixing bolt for the plug-in block is used for fixing;

[0018] Extension plate locking bolts are installed at the positions close to the plug-in block on the tops of the positioning block and the splicing block, and the extension plate locking bolts are screwed downwards into the through holes in the extension plate to fix the plug-in block to the splicing block or the positioning block together.

[0019] Preferably, buckle holes are formed at the top or bottom ends of the two connecting pieces. Two upper and lower elastic buckles are arranged on both sides of the splicing block of the mounting seat. The two elastic buckles respectively correspond to the upper and lower two connecting pieces. When the connecting pieces are stored in the splicing block, the connecting pieces are fixed by the elastic buckles;

[0020] The elastic buckle is installed in the inner cavity of the splicing block. The elastic buckle is composed of an adjusting pin and a sliding rod. Springs are sleeved on both the adjusting pin and the sliding rod. A buckle seat is installed at the bottom of the sliding rod. An extending rod extending outwards is arranged at the bottom of the buckle seat, and the end of the extending rod is set as a round abutting head;

[0021] When the sliding rod moves outwards, the abutting head is inserted into the buckle hole of the connecting piece, and the connecting piece is fixed by the abutting head of the sliding rod;

[0022] Inclined surfaces are arranged on both sides of the buckle seat, and two adjusting pins are arranged and clamped on both sides of the buckle seat; an inclined abutting surface is arranged at one end of the adjusting pin close to the buckle seat, and the abutting surface is located below the inclined surface of the buckle seat. A ball is arranged at the bottom surface of the buckle seat; the abutting surface is clamped with the inclined surface of the buckle seat. When the adjusting pin moves inwards, the buckle seat and the sliding rod are jacked upwards, and the abutting head is disengaged from the connection with the connecting piece. At this time, the fixing of the connecting piece is released;

[0023] When the adjusting pin moves outwards, the sliding rod moves downwards driven by the spring, and the abutting head approaches the connecting part through the movement; the ball is used to assist the movement of the adjusting pin, and the friction force of the abutting surface is reduced by the rolling of the ball.

[0024] Preferably, a pin handle is fixed to the outer end of the adjusting pin, and a retaining ring is arranged at the connection between the pin handle and the adjusting pin for limiting. When the pin handle moves inwards, the spring on the adjusting pin is squeezed by the retaining ring. After releasing the squeezing, the spring on the adjusting pin rebounds and the retaining ring restores the initial position of the adjusting pin; one end of the spring on the sliding rod abuts against the buckle seat, and the other end abuts against the inner wall of the splicing block;

[0025] The pin handle extends to the outside of the splicing block. A receiving groove is formed on one side of the splicing block in the splicing seat close to the pin handle. When the splicing block of the mounting seat abuts against the splicing block of the splicing seat, the pin handle is inserted into the receiving groove.

[0026] Preferably, a hollowed-out plate is embedded in the top of the supporting seat. A rhombic hole is arranged in the middle of the inner cavity of the hollowed-out plate. Hollowed-out slits are formed at the top and bottom of the hollowed-out plate, and the hollowed-out slits communicate with the rhombic hole; Venting grooves are symmetrically arranged at the top of the side surfaces of the flat block, the first arc-shaped block, and the second arc-shaped block, and the venting grooves communicate with the hollowed-out plate inward for heat dissipation through the hollowed-out plate; A hollowed-out plate is also embedded in the top of the connecting head, and the hollowed-out plate on the connecting head communicates with the upper hollowed-out plate, and the inner cavity of the connecting head is hollow.

[0027] Preferably, inserting feet are symmetrically arranged on one side of the side plate close to the supporting seat. Inserting foot mounting grooves are symmetrically arranged on the flat block, the first arc-shaped block, the second arc-shaped block, and the connecting head. The side plate is flexibly mounted on the supporting seat through the inserting feet and the inserting foot mounting grooves.

[0028] Preferably, a plug pin is arranged inside the side plate. The plug pin is composed of a plug pin rod, a return spring, and a toggle bolt. A cavity for the movement of the plug pin is formed inside the side plate. A sliding groove is formed at the top of the side plate, and the toggle bolt is inserted into the sliding groove. The toggle bolt moves in the sliding groove and pushes one end of the plug pin rod into the panel groove. A plug pin hole is horizontally penetrated through the mounting block. When the mounting block is inserted into the panel groove, the moving plug pin rod is inserted into the plug pin hole to fix the static elimination device;

[0029] A limiting groove is formed on one side of the inner cavity of the panel groove facing the plug pin rod. A protruding plug is arranged at one end of the plug pin rod, and the plug is inserted into the limiting groove. The limiting groove plays a role in guiding and limiting the plug pin rod.

[0030] Preferably, a return spring is sleeved on the side of the bolt rod away from the panel groove. The two ends of the return spring are respectively provided with an abutting plate and a limiting plate. The abutting plate is fixed on the bolt rod, and the limiting plate is fixed in the inner cavity of the side plate. When the toggle bolt is pushed backward, the abutting plate and the limiting plate compress the return spring. At this time, the bolt rod is received in the side plate, and the bolt rod releases the fixation of the mounting block. When the toggle bolt is released, the return spring pushes the abutting plate and the bolt rod to move toward the panel groove through reset, achieving the purpose of fixation.

[0031] A locking groove is vertically opened on one side of the sliding groove. A bolt positioning plate is slidably arranged in the locking groove. When the bolt rod contracts, the bolt positioning plate is pushed to block the rebound of the bolt rod by using the bolt positioning plate, realizing the storage and fixation of the bolt rod.

[0032] Compared with the prior art, the present solution provides a PCB backrest tooling with flexible adjustment, having the following advantages:

[0033] Size adjustment: The mounting seat adjusts its length by increasing or decreasing the number of splicing blocks, and can expand its width by installing splicing seats. The supporting seat can also extend its length by increasing the number of flat blocks, and its width expands synchronously with the expansion of the width of the mounting seat, which can better meet the assembly requirements of LCD monitors with different size requirements; The components are flexibly connected and fixed through plugging, meshing, and screwing, which is convenient for assembly, disassembly, and adjustment;

[0034] The elastic buckle uses components such as adjusting pins, sliding rods, and springs to cooperate to firmly fix the connecting piece during storage and can be easily unlocked, further enhancing the overall stability and usability of the structure;

[0035] Tooling heat dissipation: A hollowed-out plate is embedded in the top of the supporting seat and is interconnected with the air vents on the sides of the flat block, the first arc block, and the second arc block, forming an effective heat dissipation channel, which helps to timely dissipate the heat generated during the assembly of the LCD monitor and ensure the normal operation of the equipment;

[0036] Equipped with an anti-static device: An anti-static device composed of a mounting panel and an ion wind rod is arranged on one side of the supporting seat, effectively reducing the influence of static electricity on electronic components and the like during the assembly of the LCD monitor, improving the assembly quality and product performance; The anti-static device can be conveniently fixed on the supporting seat through the operation of the bolt in the side plate, and the installation method of each component is relatively simple, which is convenient for operation and use.

The first arc block 202 is arranged inside the second arc block 203. The flat block 201 is arranged inside the first arc block 202. There are multiple flat blocks 201. Increasing the number of flat blocks 201 extends the length of the socket 20; Socket fixing rods 204 are provided at the bottoms of the flat block 201, the first arc block 202, and the second arc block 203;

[0082] Splicing seats 30 are installed on both sides of the mounting seat 10 to extend the width of the mounting seat 10. The splicing seats 30 are also composed of a positioning block 101, a splicing block 102, and a plug-in block 103. The splicing structure of the positioning block 101, the splicing block 102, and the plug-in block 103 is the same as the splicing structure of the mounting seat 10;

[0083] A rotating shaft 102-1 is arranged inside the splicing block 102 of the mounting seat 10. Two connecting pieces 102-4 are sleeved on the rotating shaft 102-1. The two connecting pieces 102-4 rotate independently, and when splicing, the two connecting pieces 102-4 face the splicing seats 30 on both sides respectively; through holes 102-5 are formed through the middle parts of the connecting pieces 102-4;

[0084] Splicing fixing bolts 301 are arranged in the splicing blocks 102 of the splicing seats 30. Rotate the connecting pieces 102-4 in the mounting seat 10 into the splicing blocks 102 of the splicing seats 30, and then the splicing fixing bolts 301 are lowered to fix the connecting pieces 102-4. The mounting seat 10 and the splicing seat 30 are fixed together through the connection between the connecting pieces 102-4 and the splicing fixing bolts 301, completing the width expansion of the mounting seat 10;

[0085] Support seats 20 are also arranged on the tops of the splicing seats 30. The adjacent support seats 20 are abutted against each other to synchronously expand the width of the support seats 20;

[0086] Snap holes 102-6 are formed at the top or bottom ends of the two connecting pieces 102-4. Two upper and lower elastic buttons 104 are arranged on both sides of the splicing block 102 of the mounting seat 10. The two elastic buttons 104 respectively correspond to the upper and lower two connecting pieces 102-4.

When the adjusting pin 104-1 moves inwards, the buckle seat 104-4 and the sliding rod 104-3 are jacked upwards, and the abutting head is disengaged from the connection with the connecting piece 102-4. At this time, the fixing of the connecting piece 102-4 is released.

[0090] When the adjusting pin 104-1 moves outwards, the sliding rod 104-3 moves downwards under the drive of the spring 104-5, and the abutting head is moved closer to the connecting piece 102-4 through the movement. The ball 104-6 is used to assist the movement of the adjusting pin 104-1, and the friction of the abutting surface 104-2 is reduced through the rolling of the ball 104-6.

[0091] A pin handle 104-7 is fixed to the outer end of the adjusting pin 104-1. A retaining ring is arranged at the connection between the pin handle 104-7 and the adjusting pin 104-1 for limiting. When the pin handle 104-7 moves inwards, the spring 104-5 on the adjusting pin 104-1 is squeezed through the retaining ring. After releasing the squeezing, the spring 104-5 on the adjusting pin 104-1 rebounds and the retaining ring restores the initial position of the adjusting pin 104-1. One end of the spring 104-5 on the sliding rod 104-3 abuts against the buckle seat 104-4, and the other end abuts against the inner wall of the splicing block 102.

[0092] The pin handle 104-7 extends to the outside of the splicing block 102. A receiving groove is formed on one side of the splicing block 102 in the splicing seat 30 close to the pin handle 104-7.
