Description

Technical Field

[0001] This utility model belongs to the field of board separation fixture technology, specifically relating to a high-precision SMT component placement board separation fixture. Background Technology

[0002] SMT generally refers to Surface Mount Technology (SMT). SMT is an abbreviation for a series of processes performed on a PCB (Printed Circuit Board). SMT is a popular technology and process in the electronics assembly industry. After SMT assembly, precision separation fixtures are required on the PCB.

[0003] A high-precision SMT placement intelligent board separation fixture, patent publication number CN213638393U, is described in the prior art. This patent includes a fixture frame, with L-shaped connecting rods on the back of each frame. One end of each L-shaped connecting rod is bolted to the back of the fixture frame. Connecting grooves extend through the sides of the L-shaped connecting rods, and rotating shafts are embedded within each groove. Connecting protrusions are fixed between two rotating shafts. A head cover is provided on the front of the connecting protrusion, and the head cover cooperates with the fixture frame. Double connecting rods are provided at the bottom of each head cover, with rotating shafts sleeved to the double connecting rods, and the head cover and double connecting rods axially connected. The use of a rotating shaft and connecting protrusions allows for boltless installation of the equipment's head cover, facilitating direct closure of the equipment and subsequent processing, thus improving installation efficiency. However, in practical use, the following shortcomings remain: Firstly, the equipment can only separate one SMT component at a time, significantly reducing work efficiency. Secondly, after separation, it cannot easily collect the separated SMT components, increasing labor costs. Thirdly, the equipment cannot flexibly clamp SMT components of different lengths and widths, limiting its usability and failing to meet the needs of operators, thus lacking practicality.

[0004] Therefore, a high-precision SMT placement and separation fixture is needed to solve the problems of existing technologies that can only perform separation operations on one SMT component at a time, cannot easily collect separated SMT components, and cannot flexibly clamp SMT components of different lengths and widths for convenient separation.

Detailed Implementation

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4This utility model provides a high-precision SMT component placement and separation fixture, comprising: a fixed base 100, fixed plates 104 fixedly connected to both ends of one side surface of the fixed base 100, a rotating component 200 provided on one side of the fixed plate 104, a placement platform 106 provided between the fixed plates 104, a groove 107 provided on one side surface of the placement platform 106, a clamping component 300 provided in the groove 107, a partition plate 109 fixedly connected to one side surface of the placement platform 106, a collection box 102 provided on one side surface of the fixed base 100, a handle 103 fixedly connected to one side surface of the collection box 102, and mounting holes 101 provided around one side surface of the fixed base 100. The placement platform 106 is used to place SMT components to be separated. The separator 109 allows for the separation of two SMT components at a time. The collection box 102 is used to collect the separated SMT components. The collection box 102 has a buffer pad inside to reduce the impact when the SMT components fall and be collected, thus reducing damage to the SMT components. When the collection box 102 is full, it can be transferred to a designated location using the handle 103.

[0023] The rotating assembly 200 includes a mounting groove 201. One side surface of the mounting groove 201 is fixedly connected to one side surface of the fixing plate 104. A first mounting frame 202 is fixedly connected to one end surface of the mounting groove 201. A servo motor 203 is fixedly connected inside the first mounting frame 202. A first threaded rod 204 is rotatably connected inside the mounting groove 201. One end surface of the first threaded rod 204 is fixedly connected to the output end of the servo motor 203. When the switch of the servo motor 203 is turned on, the first threaded rod 204 is driven to rotate through the output end of the servo motor 203.

[0024] A first sliding rod 205 is fixedly connected inside the mounting slot 201. A rack 206 is slidably connected to the first sliding rod 205, and the rack 206 is threadedly connected to a first threaded rod 204. The rotation of the first threaded rod 204 drives the rack 206 to move on the first sliding rod 205.

[0025] A rotating shaft 105 is rotatably connected to one side surface of the fixed plate 104. One end surface of the rotating shaft 105 is fixedly connected to one end surface of the placement platform 106. A transmission gear 108 is fixedly connected to one end surface of the fixed plate 104 through the rotating shaft 105. The transmission gear 108 meshes with a rack 206. The movement of the rack 206 drives the transmission gear 108 to rotate, and the rotating shaft 105 of the transmission gear 108 rotates, which in turn drives the placement platform 106 to rotate synchronously.

[0026] The clamping assembly 300 includes a second mounting frame 301 and a bidirectional motor 302. One end surface of the second mounting frame 301 is fixedly connected to one side surface of the groove 107. The second mounting frame 301 is fixedly connected to the bidirectional motor 302. A second threaded rod 303 is fixedly connected to the output end of the bidirectional motor 302. The end surface of the second threaded rod 303 away from the bidirectional motor 302 is rotatably connected to the two side surfaces of the groove 107. Second sliding rods 304 are fixedly connected to both sides inside the groove 107. When the switch of the bidirectional motor 302 is turned on, the output end of the bidirectional motor 302 drives the second threaded rod 303 to rotate.

[0027] The placement platform 106 has sliding grooves 305 at both ends on one side surface. Moving plates 306 are slidably connected to both ends of the sliding grooves 305. The moving plates 306 are threadedly connected to the second threaded rod 303 and slidably connected to the second sliding rod 304. A U-shaped clamping plate 307 is fixedly connected to one end surface of the moving plates 306. Rotation of the second threaded rod 303 drives the two moving plates 306 to move relative to each other on the second sliding rod 304. The movement of the moving plates 306 causes the U-shaped clamping plate 307 to move synchronously.

[0028] Electronic telescopic rods 308 are provided on both sides of the U-shaped clamping plate 307, and rubber pads 309 are fixedly connected to the output ends of the electronic telescopic rods 308. The output ends of the electronic telescopic rods 308 can drive the rubber pads 309 to move, and the rubber pads 309 can elastically clamp the surface of the SMT pads, reducing wear on the SMT pads.

[0029] According to the above working process, the operator first uses expansion bolts to fix the fixed base 100 in the designated position through the mounting holes 101, thereby fixing the equipment for board separation. When it is necessary to separate SMT components, the operator can place two SMT components on the placement table 106 at the same time, so that one end of the two SMT components abuts against the two sides of the separator plate 109. Then, the switch of the bidirectional motor 302 is turned on, and the output end of the bidirectional motor 302 drives the second threaded rod 303 to rotate. The rotation of the second threaded rod 303 drives the two moving plates 306 to move relative to each other on the second sliding rod 304. The movement of the moving plates 306 drives the U-shaped clamping plate 307 to move synchronously, thereby fixing the other end of the two SMT components. Then, the output of the electronic telescopic rod 308... The end of the device moves the rubber pad 309 to fix both sides of the SMT chip. Then, the operator separates the chips. After separation, the operator turns on the servo motor 203. The output of the servo motor 203 drives the first threaded rod 204 to rotate. The rotation of the first threaded rod 204 drives the rack 206 to move on the first sliding rod 205. The movement of the rack 206 drives the transmission gear 108 to rotate. The transmission gear 108 drives the rotating shaft 105 to rotate synchronously, thereby causing the placement table 106 to flip. Then, the clamping of the SMT chip is released, and the SMT chip falls into the collection box 102 for collection. This meets the needs of the operator, improves work efficiency, has a wide range of applications, ensures the quality of SMT chip separation, and greatly improves the practicality of the equipment.
