Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a circuit board testing machine which is used for automatically detecting a circuit board. The circuit board may be a ceramic circuit board, an alumina ceramic circuit board, an aluminum nitride ceramic circuit board, a flexible circuit board, etc., which is not limited in the embodiments of the present application. The circuit board testing machine may detect the circuit board by shape and position detection of the circuit board, or by signals of the circuit board, and the like, which is not limited in the embodiment of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a circuit board testing machine according to an embodiment of the present disclosure. The circuit board testing machine may include a rack 100, a number of circuit board testing devices 200, a driving device 300, and a multi-axis robot 400.

As shown in fig. 1, a plurality of circuit board testing devices 200 are disposed on the rack 100, and the circuit board testing devices 200 are used for testing circuit boards. Different circuit board testing devices 200 can be set according to the change of the testing items required by the circuit board to perform signal testing, appearance testing and the like on the circuit board. The driving device 300 is disposed on the frame 100. The multi-axis robot 400 is drivingly connected to the driving device 300. So that the multi-axis robot 400 can be moved by the driving of the driving device 300. The multi-axis robot 400 is used for clamping the circuit board, and the circuit board can be alternately transferred to different circuit board testing devices 200 for corresponding testing through the cooperative motion of the multi-axis robot 400 and the driving device 300.

It can be understood that, in the actual operation process, the circuit board testing apparatus 200 tests the circuit board for a longer time, and the multi-axis robot 400 transfers the circuit board to the circuit board testing apparatus 200 for a shorter loading time. Therefore, if a multi-axis manipulator 400 is used in conjunction with a circuit board testing device 200, the overall efficiency of the circuit board testing machine will be low. In contrast, in the embodiment of the present application, the multi-axis manipulator 400 is used in conjunction with a plurality of circuit board testing devices 200, so as to greatly improve the working efficiency of the circuit board testing machine.

It can be further understood that, since the movable range of the multi-axis manipulator 400 is limited, the operation range of the multi-axis manipulator 400 can be expanded by driving the multi-axis manipulator 400 by the driving device 300, so that the multi-axis manipulator 400 can operate with more circuit board testing devices 200, and the testing efficiency of the circuit board testing machine provided by the embodiment of the present application can be further improved.

As shown in fig. 1, the rack 100 may include a table 11 and a top frame 12 erected above the table 11. The top frame 12 may be formed by welding a square tube of 80mm × 80mm, or may be manufactured by using other structures or processes, which is not limited in this embodiment. All the board testing apparatuses 200 are disposed on the table 11, and the multi-axis robot 400 is disposed on the upper frame 12.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a multi-axis manipulator and a driving device of the circuit board testing machine shown in fig. 1. The driving device 300 may include a first slide table 31 and a timing belt mechanism 33, and the first slide table 31 is slidably mounted on the upper frame 12 by a first guide rail pair 32. The timing belt mechanism 33 is provided on the top chassis 12, and drives the first slide table 31 to slide.

Optionally, a screw rod transmission mechanism, a linear motor, an electric push rod, a sliding table cylinder and other power sources can be used to replace the synchronous belt mechanism 33 to drive the first sliding table 31 to slide, and the embodiment of the application does not limit the sliding table.

As shown in fig. 2, the multi-axis robot 400 may include a six-axis robot arm 41 and a jig 42. The base 2111 of the six-axis mechanical arm 41 is connected and fixed with the first sliding table 31, so that the six-axis mechanical arm 41 is in transmission connection with the driving device 300, the driving device 300 can drive the six-axis mechanical arm 41 to move, the six-axis mechanical arm 41 drives the jig 42 to move, and the jig 42 is used for taking and placing circuit boards.

The jig 42 may include a first mounting plate 421 and an adsorption member 422. The first mounting plate 421 is in transmission connection with the six-axis mechanical arm 41, so that the six-axis mechanical arm 41 can drive the first mounting plate 421 to perform multi-axis movement. The adsorption member 422 is fixedly disposed on the first mounting plate 421, and the adsorption member 422 is used for sucking the circuit board.

The adsorption piece 422 can be a suction nozzle, a vacuum chuck and other components capable of adsorbing the circuit board, and if the circuit board is provided with magnetic components, the adsorption piece 422 can also be an electromagnet and the like, which is not limited in the embodiment of the application. The number of the suction members 422 may be one, two, three, or four, and taking the suction member 422 as a suction nozzle as an example, the number of the suction members 422 may be four, and the four suction members 422 are respectively located at four corners of the first mounting plate 421.

Of course, in some other embodiments, the fixture 42 may further include a clamping component for clamping the circuit board, which is not limited in this application.

As shown in fig. 1, a plurality of circuit board testing devices 200 may be arranged in two rows. The number of the circuit board testing devices 200 in each column may be two, three, four, etc., which is not limited in this embodiment. And the multi-axis robot 400 is positioned between two columns of the circuit board testing devices 200.

It is understood that, in the embodiment of the present application, the multi-axis robot 400 is disposed between two rows of the circuit board testing devices 200, and compared with the multi-axis robot 400 disposed in an area outside two rows of the circuit board testing devices 200, a total stroke of the multi-axis robot 400 sequentially transferring one circuit board to all the circuit board testing devices 200 can be greatly shortened, thereby further improving the testing efficiency of the circuit board testing machine provided in the embodiment of the present application.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a circuit board testing apparatus of the circuit board testing machine shown in fig. 1. Each circuit board testing device 200 may include a clamping mechanism 21 and a testing mechanism 22. The clamping mechanism 21 is connected to the frame 100 and is used for clamping a circuit board. The testing mechanism 22 is disposed on the clamping mechanism 21 and used for performing signal testing on the circuit board clamped by the clamping mechanism 21.

The testing mechanism 22 may be provided as one, or may be provided as two, three, or even four, which is not limited in this embodiment. For example, the testing device 22 may be provided in two, and the two testing devices 22 are respectively located on different sides of the clamping device 21. Therefore, after the circuit board is placed in the clamping mechanism 21, the two testing mechanisms 22 perform signal testing on the circuit board from different sides.

Referring to fig. 4 to 6, fig. 4 is a schematic structural view of the circuit board testing device shown in fig. 3 with a portion of the base removed, fig. 5 is a schematic structural view of the circuit board testing device shown in fig. 3, and fig. 6 is a schematic structural view of a testing mechanism of the circuit board testing device shown in fig. 3. Each testing mechanism 22 may include a testing assembly 221, a first driving member 222, a track plate 223, and a first connector 224.

As shown in fig. 5, the plurality of test assemblies 221 are arranged along the first direction, so that different test assemblies 221 can be selected to test the circuit board according to the model change of the circuit board and/or the change of the test requirement. The testing component 221 is slidably mounted on the clamping mechanism 21 along the second direction to be in butt joint with or separated from the circuit board clamped by the clamping mechanism 21, so that the testing component 221 is fixedly connected with the circuit board clamped by the clamping mechanism 21. The second direction is different from the first direction.

On the other hand, as shown in fig. 4 and 6, the first driving member 222 is provided to the chuck 21. The track plate 223 is capable of moving in the second direction by the first driving part 222. The first connector 224 is slidably connected to the track plate 223, and the first connector 224 can slide along a first direction to connect to different testing assemblies 221. Furthermore, when the first connecting piece 224 is connected with different test assemblies 221, the first driving part 222 can drive the track plate 223 to move, the track plate 223 can drive the first connecting piece 224 to move, and the first connecting piece 224 can drive the corresponding test assembly 221 to move, so that the different test assemblies 221 can be butted with or separated from the circuit board clamped by the clamping mechanism 21, and the test operation of the circuit board is completed.

It can be seen that the testing mechanism 22 provided in the embodiment of the present application can be connected to different testing assemblies 221 by sliding the first connector 224 according to the change of the model and/or testing requirements of the circuit board. Therefore, the testing mechanism 22 provided by the embodiment of the application has the advantages of good universality and easiness in adjustment.

In some embodiments, the track plate 223 may be provided with a first track arranged along the first direction, and one end of the first connecting member 224 near the track plate 223 is provided with a first sliding groove in sliding fit with the first track, so that the first connecting member 224 can move on the track plate 223 along the first direction.

Alternatively, as shown in fig. 5, the rail plate 223 may be provided with a rail groove 2231 arranged in the first direction, and one end of the first connector 224 is provided in the rail groove 2231, so that the first connector 224 can slide in the rail groove 2231 in the first direction to be connected with a different test assembly 221.

Referring to fig. 7, fig. 7 is an exploded view of a testing mechanism of the circuit board testing device shown in fig. 3. The first connector 224 is clamped with the test assembly 221, so that the first connector 224 can be quickly assembled and disassembled with different test assemblies 221. Illustratively, the first connector 224 is provided with a card slot 2241, and the test component 221 can be placed in the card slot 2241 for clamping and fixing. The opening of the catching groove 2241 faces opposite to the opening of the rail groove 2231. For example, the opening of the track groove 2231 is arranged upward, the opening of the clamping groove 2241 is arranged downward, and then when the first connector 224 is lifted upward, the first connector 224 can be separated from the track plate 223 and the testing component 221 at the same time, and when the first connector 224 moves downward, the first connector 224 can be connected with the track plate 223 and the testing component 221 at the same time, so as to achieve the purpose of quick installation of the first connector 224.

As shown in fig. 7, in order to prevent the test assembly 221 from being damaged due to the erroneous stroke of the test assembly 221, which may cause the test assembly 221 to press against the circuit board clamped by the clamping mechanism 21 when the circuit board is in butt joint, the first connecting member 224 may be connected to the test assembly 221 through the buffer assembly 225, so that the first connecting member 224 and the test assembly 221 can move relatively in the second direction within a predetermined range.

Furthermore, after the testing component 221 is abutted against the circuit board clamped by the clamping mechanism 21, if the first driving component 222 continues to drive the first connecting component 224 to move towards the circuit board clamped by the clamping mechanism 21, the buffering component 225 can play a role in buffering, so that the testing component 221 is fixed relative to the circuit board, and the testing component 221 and the first connecting component 224 move towards each other, thereby preventing the testing component 221 from being pressed against each other and damaged when the testing component 221 is abutted against the circuit board clamped by the clamping mechanism 21.

As shown in fig. 7, the damping assembly 225 may include a guide post 2251, a push plate 2252, and an elastic member 2253. The guide post 2251 is slidably mounted to the test assembly 221 in a second direction. The push plate 2252 is disposed at an end of the guide post 2251 away from the testing assembly 221, and the push plate 2252 is connected to the first connector 224. The resilient member 2253 is pre-stressed between the test assembly 221 and the push plate 2252. The elastic member 2253 may be a compression spring, and the compression spring is sleeved on the guide post 2251, and further, after the testing component 221 is abutted to the circuit board clamped by the clamping mechanism 21, if the first driving member 222 continues to drive the first connecting member 224 to move toward the circuit board clamped by the clamping mechanism 21, the elastic member 2253 may be compressed to play a role in buffering.

The test assembly 221 may include a first slider 2211 and a first joint 2212. The first slider 2211 is detachably slidably mounted to the clamper 21 in the second direction. The first connector 2212 is fixedly arranged on the first slider 2211. Correspondingly, the circuit board is provided with a second connector, when the circuit board is clamped to the clamping mechanism 21, the first connector 2212 can slide along with the first slider 2211 to be in butt joint with the second connector to realize electric connection, and then the test component 221 performs signal test on the circuit board clamped by the clamping mechanism 21. Of course, when the circuit board clamped by the clamping mechanism 21 is tested, the first connector 2212 can also slide to be separated from the second connector along with the first slider 2211.

The first connector 2212 may be a usb (universal Serial bus) connector or an hdmi (high Definition Multimedia interface) connector, which is not limited in this embodiment.

As shown in fig. 7, in order to enable the first connector 2212 to be accurately abutted with the second connector of the circuit board, the testing assembly 221 may further include a guide component 2213, the guide component 2213 is disposed on the first slider 2211, and the guide component 2213 is used for guiding the position of the circuit board clamped by the clamping mechanism 21.

Illustratively, the guiding component 2213 includes a rolling member rotatably disposed on the first slider 2211, and the rolling member is located on a side of the first connector 2212 close to the circuit board clamped by the clamping mechanism 21 and can be in rolling engagement with the circuit board clamped by the clamping mechanism 21. In practical applications, the rolling element may be a ball bearing or a shaft sleeve, and the like, which is not limited in this application.

Specifically, the circuit board clamped by the clamping mechanism 21 may have a certain degree of freedom, and in the process that the test assembly 221 approaches the circuit board clamped by the clamping mechanism 21, the rolling member contacts the circuit board clamped by the clamping mechanism 21 first; at this time, the rolling member and the circuit board clamped by the clamping mechanism 21 generate rolling friction, so that the circuit board clamped by the clamping mechanism 21 can be pushed by the rolling member to realize position centering. Then, after the circuit board clamped by the clamping mechanism 21 is centered, the first connector 2212 is butted with the second connector of the circuit board clamped by the clamping mechanism 21, so that the first connector 2212 and the second connector are prevented from being damaged due to collision caused by dislocation of the circuit board clamped by the first connector 2212 and the clamping mechanism 21.

As shown in fig. 3, the chuck 21 may include a carrier assembly 211, a pressing assembly 212, and a second driving assembly 213.

The carrier assembly 211 is fixedly connected to the frame 100 and is configured to receive a circuit board transferred by the multi-axis robot 400. The second driving assembly 213 is fixedly connected with the carrier assembly 211, and the second driving assembly 213 can drive the compressing assembly 212 to move. Therefore, the pressing component 212 can be moved to a position far away from the carrier component 211 for avoiding, so that the multi-axis robot 400 can place a circuit board to be detected on the carrier component 211, or the multi-axis robot 400 can take away the detected circuit board on the carrier component 211. Alternatively, the pressing assembly 212 can move to press the circuit board on the carrier assembly 211 or release the circuit board on the carrier assembly 211, so that the testing mechanism 22 can perform signal testing on the circuit board clamped by the clamping mechanism 21.

As shown in fig. 3 and 5, the carrier assembly 211 may include a base 2111, a first support 2112, an object stage 2113, and a first positioning element 2114. The base 2111 may be fixedly disposed on the frame 100. The first brackets 2112 are provided on the base 2111. The stage 2113 is attached to a side of the first frame 2112 opposite to the base 2111, and the stage 2113 is adapted to receive a board transferred by the multi-axis robot 400. A first alignment feature 2114 is provided on the stage 2113 to align and position a circuit board placed on the stage 2113 by the multi-axis robot 400.

As shown in fig. 5, the first detent 2114 may include a number of detents. When the multi-axis manipulator is used specifically, the circuit board is provided with corresponding positioning holes, so that the positioning holes in the circuit board penetrate into the positioning pins in the process of placing the circuit board on the objective table 2113 from top to bottom by the multi-axis manipulator 400, so that the circuit board is limited horizontally by the positioning pins, and the circuit board has the degree of freedom in the vertical direction.

Referring to fig. 8, fig. 8 is a schematic structural view of a pressing assembly and a portion of a second driving assembly of the circuit board testing device shown in fig. 3.

As shown in fig. 8, the compression assembly 212 may include a mounting plate 2121 and a compression member 2122, the compression member 2122 being detachably disposed on the mounting plate 2121. Further, when the mounting plate 2121 and the stage 2113 are moved toward each other, the hold-down element 2122 may also be moved toward the stage 2113 so that the hold-down element 2122 may hold down the circuit board on the stage 2113. When the mounting plate 2121 and the stage 2113 are moved away from each other, the hold-down element 2122 may likewise be moved away from the stage 2113 to release the circuit board from the stage 2113 so that the circuit board may be removed from the stage 2113 by the multi-axis robot 400 or directly by an operator.

It will be appreciated that the shape and position of the hold-down element 2122 may be adjusted according to the circuit board to be tested, and the hold-down element 2122 is detachably connected to the mounting plate 2121 such that the hold-down assembly 212 of the embodiment of the present application can rapidly replace the hold-down element 2122 to meet different testing requirements of the circuit board.

As shown in fig. 8, the pressing assembly 212 may further include a connecting plate 2123, and a plurality of pressing members 2122 are fixedly disposed on the connecting plate 2123. The mounting plate 2121 may be provided with a clamping structure 2124, and the clamping structure 2124 can clamp or release the connecting plate 2123, so that the clamping structure 2124 can be connected in a quick-release manner, thereby achieving one-time replacement of the plurality of pressing members 2122.

In practical use, the clamping component may be a cylinder or a quick clamp, and the embodiment of the present application is not limited thereto. For example, the clamping member may be a quick clamp that is mounted on the mounting plate 2121 and clamps the attachment plate 2123 below the mounting plate 2121 when the attachment plate 2123 is placed below the mounting plate 2121. Conversely, the connecting plate 2123 and the hold-down element 2122 can be replaced by releasing the quick clamp.

The second driving assembly 213 may include a power assembly for driving the compressing assembly 212 to perform a single-axis motion, or may be a power assembly for driving the compressing assembly 212 to perform a two-axis, three-axis, and other multi-axis motions, which is not limited in this embodiment of the present application.

The platen assembly provided in the embodiment of the present application is further explained below by taking the second driving assembly 213 for driving the pressing assembly 212 to perform two-axis movement as an example:

as shown in fig. 4, the second drive assembly 213 may include a second drive component 2131, a second bracket 2132, and a third drive component 2133. The second driving part 2131 is disposed on the base 2111 and is capable of driving the second bracket 2132 to move in a third direction. A third drive assembly 2133 is disposed on the second support 2132 and is capable of driving the compression assembly 212 in a fourth direction.

The third direction is different from the fourth direction, for example, the third direction is a horizontal direction, the fourth direction is a vertical direction, or the third direction is a vertical direction, and the fourth direction is a horizontal direction, which is not limited in this embodiment of the present application. The technical solution of the embodiment of the present application is further explained and explained below by taking the third direction as a substantially horizontal direction and the fourth direction as a substantially vertical direction as an example:

as shown in fig. 3, the base 2111 may be a hollow structure including a first bottom plate and a first top plate 2111b disposed opposite in a vertical direction. The first bottom plate and the first top plate 2111b are connected by a plurality of first side plates 2111c, and enclose an installation cavity. Wherein at least one first side plate 2111c is hinged to the first base plate by a hinge, such that the mounting cavity can be opened by rotating the hinge.

A second drive component 2131 may be disposed on a base 2111. For example, as shown in fig. 4, the second driving member 2131 is fixed to the first top plate 2111b in the mounting cavity. The second driving component 2131 may be a cylinder, a screw rod transmission mechanism, a linear motor, an electric push rod, a sliding table cylinder, or other linear power sources, which is not limited in this embodiment of the application.

As shown in fig. 4, the bottom of the second support 2132 is slidably mounted on the base 2111 and is in driving connection with the second driving component 2131, so that the second driving component 2131 can drive the second support 2132 to move along the third direction. For example, the second support 2132 can be a gantry. As shown in fig. 3, a second sliding groove 2111d is formed between the first side plate 2111c and the first top plate 2111b, vertical plates on two sides of the second support 2132 can slidably penetrate through the second sliding groove 2111d along the third direction, so that the bottom of the vertical plate of the second support 2132 can extend into the installation cavity, and a sliding plate 2134 is connected to a portion of the second support 2132 extending into the installation cavity. Slide 2134 is slidably connected to first top plate 2111 b. The sliding plate 2134 is also in transmission connection with the second driving member 2131, for example, when the second driving member 2131 is a screw transmission mechanism, the sliding plate 2134 is in sliding connection with a screw slider of the screw transmission mechanism.

As shown in fig. 4, the third driving member 2133 is fixedly connected to the second bracket 2132. The third driving part 2133 is outside the mounting cavity and above the carrier assembly 211. The third driving component 2133 may be a cylinder, a screw rod transmission mechanism, a linear motor, an electric push rod, a sliding table cylinder, or other linear power sources, which is not limited in this embodiment of the application.
