Description

Technical Field

[0001] This invention relates to a pressing mechanism that prevents the positioning element from wobbling arbitrarily and allows for precise positioning with fine adjustments, ensuring that the presser firmly presses against the electronic components. Background Technology

[0002] Nowadays, electronic components have an increasing number of contacts, ranging from a few to dozens. Correspondingly, the test socket of the test device must also be equipped with the same number of probes to electrically contact the contacts of the electronic components. Since the probes have internal springs, in order to ensure that the contacts of the electronic components and the probes of the test socket make reliable electrical contact, the test device uses a pressure device to press the electronic components with a default downward pressure, causing the electronic components to compress the springs of the probes. However, whether the downward pressure of the pressure device is too high or too low will affect the test quality.

[0003] Please see Figure 1 The testing device is equipped with an electrically connected circuit board 12 and a test stand 13 on the machine base 11. The test stand 13 is equipped with dozens of probes 131 for supporting and testing electronic components 14. A pressure device 16 driven by a moving arm 15 is arranged above the test stand 13. The pressure device 16 has a diaphragm 161, an air chamber 162 and a pressure fixture 163 inside. The air chamber 162 is connected to a gas supply device via a delivery pipe (not shown). The pressure device 16 has two positioning members 164 at the bottom. During testing, the moving arm 15 drives the pressure device 16 to move downward in the Z direction, so that the positioning members 164 are first aligned and inserted into the positioning holes 132 of the test stand 13. Then, the gas supply device (not shown) injects gas into the air chamber 162, causing the diaphragm 161 to bulge downward and deform, and push the pressure fixture 163 to move downward in the Z direction to press the electronic components 14, so that the electronic components 14 perform testing operations in the test stand 13.

[0004] Because the moving arm 15 drives the pressure unit 16 to make a rigid displacement in the Z direction, if there is a positional difference between the positioning member 164 and the positioning hole 132, the pressure unit 16 cannot correct the positioning member 164, resulting in the positioning member 164 being unable to insert into the positioning hole 132, which in turn affects the accuracy of the pressing of the pressure fixture 163. However, if the moving arm 15 drives the pressure unit 16 to make a soft displacement in the Z direction, the pressure unit 16 is easily pulled and shaken by gas delivery pipelines and circuit wiring, etc., and still cannot make the positioning member 164 accurately insert into the positioning hole 132, which will also affect the accuracy of the pressing of the pressure fixture 163.

[0005] Furthermore, when the springs (not shown) of the dozens of probes 131 of the test socket 13 are compressed by the pressure fixture 163, the dozens of probes 131 will generate a large reaction force on the electronic component 14. This large reaction force pushes the entire pressure unit 16 to move in the Z direction in the opposite direction through the electronic component 14, causing the pressure unit 16 to be unable to press the electronic component 14 with the default pressure. As a result, some contacts of the electronic component 14 cannot make proper contact with the probes 131 of the test socket 13, thereby affecting the test quality of the electronic component.

Detailed Implementation

[0057] To provide a better understanding of the present invention, a preferred embodiment is described in detail below with reference to the accompanying drawings:

[0058] Please see Figures 2-5 The pressing mechanism of the present invention includes a carrier structure, a driving structure, a positioning structure and a pressing structure.

[0059] The carrier structure includes at least one carrier 21. The carrier 21 can be fixed or movable. For example, the carrier 21 is fixed to the outer cover 31 of the testing device, or the carrier 21 is mounted on a transfer arm (not shown) and can be displaced in at least a first direction (such as the Z direction). In this embodiment, the carrier 21 is fixed to the outer cover 31 of the testing device and has a through hole 211 along the working axis L. The through hole 211 has at least one stop member 212, which extends inward and protrudes from the inner wall surface of the through hole 211. However, the stop member 212 can be formed on the inner wall surface of the through hole 211, or a stop member 212 as an independent component can be mounted on the through hole 211.

[0060] The drive structure includes a first base 22, a first actuator 23, a first drive unit and a floating unit; it also includes a second actuator 24 and a first return unit.

[0061] The first base 22 is mounted on the carrier 21 along the working axis L. In this embodiment, the first base 22 is mounted on the through hole 211 of the carrier 21, and a supporting member 221 is provided at the position corresponding to the stop member 212 of the carrier 21. The supporting member 221 is a recess. The first base 22 is placed across the stop member 212 of the carrier 21 by means of the supporting member 221, so as to allow for tilting and floating at an angle.

[0062] The first actuator 23 and the first base 22 are arranged opposite each other along the working axis L. In this embodiment, the first actuator 23 is arranged below the first base 22 and can be displaced in a first direction along the working axis L. The first actuator 23 is provided with at least one first linkage 231, which connects to a second actuator 24, which is located above the first base 22.

[0063] The first drive unit is used to drive the first actuator 23 to make a first rigid displacement along the working axis L; furthermore, the first drive unit is provided with a first driver between the first base 22 and the first actuator 23. The first driver can be an airbag, a piezoelectric component, or include an air chamber and a pushing component, as long as it can drive the first actuator 23 to move along the working axis L, and is not limited to this embodiment. For example, the first actuator is an airbag, which can be assembled and connected between the first base 22 and the first actuator 23. When the airbag is inflated, it drives the first actuator 23 to move. In this embodiment, the first actuator has a first air chamber and a first pushing component that cooperate with each other between the first base 22 and the first actuator 23, and has a first delivery pipe that connects to the first air chamber. Furthermore, the first actuator has a first air chamber 222 on the first base 22, and a first pushing component 232 on the top surface of the first actuator 23. The first pushing component 232 is inserted into the first air chamber 222. The first delivery pipe is provided with a first delivery pipe 223 that connects to the first air chamber 222. The first delivery pipe 223 connects to a gas supply device (not shown) and a pressure detector to supply gas to the first air chamber 222, thereby driving the first pushing component 232 to drive the first actuator 23 to move downward in the Z direction along the working axis L.

[0064] However, the drive structure can utilize the first driver to reset the first actuator 23, or, depending on operational requirements, the drive structure may further include a first reset unit to reset the first actuator 23. The first reset unit has a first reset device between the first base 22 and the first actuator 23. Furthermore, the first reset device has a cooperating second air chamber and a second pushing component between the second actuator 24 connected to the first actuator 23 and the first base 22, and a second delivery pipe connecting to the second air chamber is provided. In this embodiment, the first reset device has a second air chamber 224 on the first base 22, and a second pushing component 241 on the second actuator 24. The second pushing component 241 is inserted into the second air chamber 224. The delivery pipeline has a first delivery channel 242 connecting the second air chamber 224 in the second pushing component 241, and a second delivery channel 243 in the second actuator 24. The second delivery channel 243 connects to the first delivery channel 242, and is also connected to an air supply device (not shown) and a pressure detector to supply gas to the second air chamber 224. This drives the second pushing component 241 to move the second actuator 24 to return to its original position in the Z direction. The second actuator 24 then drives the first actuator 23 to move to its original position in the Z direction simultaneously. However, it is also permissible for the first delivery channel 242 of the second delivery pipeline to be directly connected to the air supply device.

[0065] The floating unit allows the first actuator 23 to perform a second floating displacement. Furthermore, the floating unit is equipped with at least one locking member to lock the first base 22 and prevent arbitrary shaking. The locking member is also used by the second actuator 24 to press and displace, releasing the locking of the first base 22, allowing the first base 22 to drive the first actuator 23, the positioning structure, and the pressing structure to perform a second floating displacement (e.g., in the XY direction or at a horizontal angle Θ). Furthermore, the floating unit has a first floating connection portion and a second floating connection portion that cooperate with each other between the first base 22 and the carrier 21. The first floating connection portion and the second floating connection portion can be in a mutually cooperating arc or V-shape. In this embodiment, the floating unit has at least one first receiving hole 213 with a first stop surface 214 in the carrier 21 and at least one receiving hole with a second stop surface 226 in the first base 22. The second receiving hole 225 has at least one locking member 227 fitted with a spring 228, which passes through the first receiving hole 213 and the second receiving hole 225. One end of the spring 228 rests on the first end 2271 of the locking member 227, and the other end rests on the second stop surface 226 of the second receiving hole 225, so that the spring 228 pushes the locking member 227 to move upward in the Z direction, so that the second end 2272 of the locking member 227 abuts against the first stop surface 214 of the first receiving hole 213, thereby positioning the first base 22. The floating unit has at least one first floating part 215 with an arc protrusion on the carrier 21, and at least one second floating part 229 with an arc groove at the position corresponding to the first floating part 215 on the first base 22. The second floating part 229 and the first floating part 215 cooperate to lock each other.

[0066] The positioning structure has at least one second base 251 on the first actuator 23. The second base 251 has at least one positioning member and is used to drive the first actuator 23 to perform a first rigid displacement and a second floating displacement. Furthermore, the positioning structure has a stop unit on the second base 251. The stop unit has a linkage assembly, a second driver and a hook on the second base 251. The second driver is used to drive the linkage assembly to operate. The linkage assembly is connected to at least one hook pivotally mounted on the second base 251. The hook has a hook portion so that when the hook portion is restricted, the pressure device can be limited to move in the opposite direction along the working axis L. Furthermore, the second driver has a third air chamber and a third pushing component that cooperate with each other between the second base 251 and the linkage assembly, and has a third delivery pipeline that connects to the third air chamber.

[0067] In this embodiment, the second base 251 is mounted below the first actuator 23 and has at least one positioning member 252 at its bottom. The second actuator has a third air chamber 2511 inside the second base 251. The third air chamber 2511 is equipped with a third pushing member 253 capable of Z-direction displacement. The third conveying pipeline has a second conveying pipe 2512 and a third conveying channel 244. The second conveying pipe 2512 connects to the third air chamber 2511, and the third conveying channel 244 is disposed on the second actuator 24. The second delivery pipe 2512 is connected to the gas supply equipment, allowing gas to be injected into the third gas chamber 2511 through the second delivery pipe 2512, thereby driving the third pushing component 253 to move downward in the Z direction. The third pushing component 253 is provided with at least one transmission part 2531, which is pivotally connected to and drives two connecting rods 254 of the linkage assembly. Two hook fasteners 255 are pivotally mounted on the second base 251 and are provided with hooks 2551. The two hook fasteners 255 are respectively pivotally connected to the two connecting rods 254, allowing the two connecting rods 254 to swing. However, it is also acceptable for the second delivery channel 2512 of the third delivery pipe to be directly connected to the gas supply equipment.

[0068] The positioning structure further includes a second return unit for resetting the linkage assembly and hook fastener 255; the second return unit has a second return device between the second base 251 and the linkage assembly; in this embodiment, the second return device has a fourth air chamber 2513 and a fourth pushing component 256 cooperating with each other on the second base 251, and a fourth conveying pipe communicating with the fourth air chamber 2513. The fourth conveying pipe has a third conveying pipe 2514 and a fourth conveying channel 245. The fourth gas chamber 2513 is connected, and the fourth conveying channel 245 is disposed in the second actuator 24 and connected to the third conveying pipe 2514 and the gas supply equipment. Gas is injected into the fourth gas chamber 2513 through the third conveying pipe 2514 to drive the fourth pushing component 256 to move upward in the Z direction. The fourth pushing component 256 is equipped with at least one adapter 257, which is connected to the transmission part 2531 of the third pushing component 253 by a shaft to drive the third pushing component 253 to move synchronously. However, it is also acceptable for the third conveying pipe 2514 of the fourth conveying pipeline to be directly connected to the gas supply equipment.

[0069] The pressing structure includes at least one presser 26 and a second drive unit. The at least one presser is used to press electronic components, and the second drive unit is used to drive the at least one presser 26 to perform pressing displacement along the working axis L to press the electronic components. Furthermore, the second drive unit has a third driver between the presser 26 and the first actuator 23 to drive the presser 26 to perform pressing displacement. Further still, the third driver has a cooperating fifth air chamber and a fifth pushing component between the presser 26 and the first actuator 23, and a fifth delivery pipe communicating with the fifth air chamber. In this embodiment, the presser 26 is positioned below the first actuator 23, and... At least one pressing fixture 261 is provided at the bottom for pressing electronic components. The third actuator has a fifth air chamber 262 inside the presser 26 and a fifth pushing component 233 is provided at the bottom of the first actuator 23. The fifth pushing component 233 is placed in the fifth air chamber 262. The fifth delivery pipeline includes a fifth delivery channel 2341 and a sixth delivery channel 2342. The fifth delivery channel 2341 is connected to the fifth air chamber 262, and the sixth delivery channel 2342 is connected to the fifth delivery channel 2341 and the gas supply equipment, so that the fifth delivery channel 2341 delivers gas to the fifth air chamber 262, causing the presser 26 to move downward in the Z direction.

[0070] The pressing structure further includes a third reset unit for driving the presser 26 to reset; the third reset unit is provided between the presser 26 and the first actuator 23; depending on the operation requirements, it further includes a second actuator 24, which is located above the first base 22 and is connected to the first actuator 23 by at least one first linkage 231; the third reset unit is provided between the presser 26 and the second actuator 24 with a sixth air chamber and a sixth pushing component that cooperate with each other, and is provided with a sixth delivery pipeline that connects to the sixth air chamber. In this embodiment, the third return device has a sixth air chamber 263 in the pressure reducer 26. The sixth air chamber 263 is for inserting a sixth pushing component 264. The sixth delivery pipeline includes a fourth delivery pipe 265 and a seventh delivery channel 246. The fourth delivery pipe 265 connects to the sixth pushing component 264 and communicates with the sixth air chamber 263. The seventh delivery channel 246 is disposed in the second actuator 24 and connects to the fourth delivery pipe 265 and the gas supply device to deliver gas to the sixth air chamber 263, causing the pressure reducer 26 to move upward in the Z direction for return. However, the fourth delivery pipe 265 can also be directly connected to the gas supply device.

[0071] Since the second delivery pipe 2512, the third delivery pipe 2514 and the fourth delivery pipe 265 are respectively connected to the third delivery channel 244, the fourth delivery channel 245 and the seventh delivery channel 246 of the second actuator 24, the air pipes of the second delivery channel 243, the third delivery channel 244, the fourth delivery channel 245 and the seventh delivery channel 246 can be clustered and arranged on the second actuator 24 and located above the carrier 21, which facilitates maintenance and replacement, and reduces the space occupied by multiple air pipes around the compressor 26, thus facilitating space configuration.

[0072] Please see Figure 4 , Figures 6-8 The testing device 30 of the present invention includes at least one tester and the crimping mechanism of the present invention. The at least one tester is used to test electronic components, and the crimping mechanism is used to crimp electronic components. In this embodiment, the testing device 30 is provided with an outer cover 31 on the machine base (not shown) according to the operation requirements. The inside of the outer cover 31 forms a test chamber, and the inside of the test chamber is used to accommodate the tester. According to the operation requirements, the tester can be fixed inside the outer cover 31, or the tester can be transported to the inside of the outer cover 31 by a stage (not shown), so that the tester is located in the test chamber. In this embodiment, the tester includes an electrically connected circuit board 32 and a test base 33 with probes 34 for holding and testing electronic components 41. At least one positioning hole 35 and at least one limiting member are respectively provided on the periphery of the test base 33. In this embodiment, the limiting member is a limiting rod 36 arranged in a second direction (such as the X direction). The crimping mechanism of the present invention is located above the test base 33 and can be displaced in the Z direction along the working axis L.

[0073] The first actuator of the drive structure delivers gas to the first air chamber 222 via the first delivery pipe 223. The gas in the first air chamber 222 pushes the first pushing component 232 downward along the working axis L in the Z direction. The first pushing component 232 drives the first actuator 23 to move synchronously. The first actuator 23 drives the second base 251, the pressure device 26, and the positioning component 252 to move downward in the Z direction. The first linkage 231 drives the second actuator 24 to move downward synchronously. The second actuator 24 drives the second pushing component 241 to move into the second air chamber 224 of the first base 22. Since the second actuator 24 has not yet pressed down the locking component 227, the locking component 227... The first end 2271 and the second end 2272 of 27 hold the abutting spring 228 and the first stop surface 214, and lock the carrier 21 and the first base 22 to prevent the first base 22 from shaking arbitrarily, that is, to prevent the first pushing component 232 and the second pushing component 241 in the first base 22 from driving the first actuator 23 and the second actuator 24 to shake arbitrarily, and not to be pulled by the gas delivery pipeline and circuit wiring, etc., so that the first actuator 23 drives the second base 251, the pressure device 26 and the positioning component 252 to make a first rigid displacement downward in the Z direction along the working axis L, so that the positioning component 252 first contacts the end of the positioning hole 35 of the test seat 33.

[0074] During the continuous downward displacement of the second actuator 24 driven by the first linkage 231 of the first actuator 233, the second actuator 24 presses down the first end 2271 of the locking member 227, the locking member 227 compresses the spring 228, and causes the second end 2272 to disengage from the first stop 214 of the carrier 21, thereby releasing the locking of the first base 22. This allows the first base 22 to drive the first actuator 23, the second base 251, the presser 26, and the positioning member 252 to make a second floating displacement, allowing the positioning member 252 to make a fine adjustment displacement and smoothly insert into the positioning hole 35 of the test seat 33 for positioning. The hook 2551 of the hook and buckle member 255 of the positioning structure is relative to the limiting rod 36 of the test seat 33.

[0075] Please see Figure 9 The second actuator of the positioning structure delivers gas to the third gas chamber 2511 via the third delivery channel 244 and the second delivery pipe 2512. The gas in the third gas chamber 2511 pushes the third pushing component 253 to move downward in the Z direction. The transmission part 2531 of the third pushing component 253 drives the two connecting rods 254 of the connecting rod assembly to swing. The two connecting rods 254 push the two hook fasteners 255 to swing, so that the hooks 2551 of the two hook fasteners 255 hook onto the limiting rod 36 of the test seat 33.

[0076] Please see Figure 9 , Figure 10The third actuator of the pressure-down structure delivers gas to the fifth gas chamber 262 via the fifth delivery channel 2341 and the sixth delivery channel 2342. The gas in the fifth gas chamber 262 pushes the pressure-down device 26 downward along the working axis L in the Z direction. The pressure-down device 26 presses the electronic component 41 on the test seat 33 with the pressure-down fixture 261 to perform the test operation. Since the electronic component 41 is subjected to the reaction force of multiple probes 34 and pushes the pressure-down device 26, under the condition that the fifth gas chamber 262 maintains a certain preset air pressure, the gas in the fifth gas chamber 262 pushes the first actuator 23 via the fifth pushing component 233. The first actuator 23 is positioned by hooking the hook 2551 of the two hook fasteners 255 onto the limiting rod 36 of the test seat 33, thereby effectively preventing the pressure-down device 26 and the first actuator 23 from moving in opposite directions, so that the pressure-down device 26 can reliably press the electronic component 41 to perform the test operation, thereby improving the test quality.

[0077] Please see Figure 4 , Figures 11-13 After the test is completed, the third return device of the pressure structure delivers gas to the sixth gas chamber 263 through the seventh delivery channel 246 and the fourth delivery pipe 265. The gas in the sixth gas chamber 263 pushes the pressure device 26 to move upward in the Z direction along the working axis L to reset it, so that the pressure fixture 261 of the pressure device 26 is disengaged from the electronic component 41.

[0078] The second return device of the positioning mechanism delivers gas to the fourth gas chamber 2513 through the fourth conveying channel 245 and the third conveying pipe 2514. The gas in the fourth gas chamber 2513 pushes the fourth pushing component 256 to move upward in the Z direction. The fourth pushing component 256 drives the third pushing component 253 to move upward synchronously through the adapter 257. The third pushing component 253 drives the two connecting rods 254 to swing through the transmission part 2531, causing the two connecting rods 254 to pull the two hook fasteners 255 to swing downward, causing the hooks 2551 to disengage from the limiting rod 36 of the test seat 33, thereby releasing the positioning of the first actuator 23.

[0079] The first return mechanism of the drive structure delivers gas to the second gas chamber 224 through the second delivery channel 243 and the first delivery channel 242. The gas in the second gas chamber 224 pushes the second pusher 241 to move upward in the Z direction. The second pusher 241 drives the second actuator 24 to move synchronously. The second actuator 24 drives the first actuator 23 to move upward in the Z direction along the working axis L to reset, so that the first actuator 23 drives the pressure device 26 to reset. However, when the second actuator 24 moves upward in the Z direction, it disengages from the locking member 227. The locking member 227 is pushed back by the elastic force of the spring 228 and resets, and locks the first base 22 and the carrier 21 for positioning again. When the second actuator 24 continues to move upward in the Z direction, it drives the positioning member 252 of the second base 251 to disengage from the positioning hole 35 of the test seat 33.

[0081] However, depending on the operational requirements, a blower (not shown in the figure) can be installed in the test chamber during thermal testing to blow hot air and raise the internal temperature of the test chamber. Furthermore, the pressure-reducing structure includes a temperature control unit (not shown in the figure). The temperature control unit has at least one temperature control device on the pressure-reducing unit 26 for temperature control electronic components; furthermore, the temperature control device can be a heating element, a cooling chip, or a fluid-filled base.

[0082] The conveying device 80 is mounted on the machine base 50 and is equipped with at least one transporter for conveying electronic components. In this embodiment, the conveying device 80 is equipped with a first transporter 81 that performs XYZ direction displacement to remove the electronic component to be tested from the feed holder 61 of the feeding device 60 and transfer the electronic component to be tested to the second transporter 82. The second transporter 82 carries the electronic component to be tested to the side of the testing device 30. The third transporter 83 of the conveying device 80 removes the electronic component to be tested from the second transporter 82 and transfers it to the test stand 33. The platform carries the test stand 33 and the electronic component. The electronic components are moved into the outer casing 31, and the pressing mechanism 26 presses the electronic components to perform the test. The third transporter 83 moves the tested electronic components into the fourth transporter 84. The fourth transporter 84 carries out the tested electronic components. The fifth transporter 85 of the conveying device 80 takes out the tested electronic components from the fourth transporter 84 and, according to the test results, transports the tested electronic components to the receiving container 71 of the receiving device 70 for sorting and storage. The central control device (not shown) is used to control and integrate the operation of each device to perform automated operation and achieve the practical benefits of improving work efficiency.
