[0023] Combination Figure 1 As shown, the keyboard testing mechanism provided in this application includes: Carrier assembly 200, one side of carrier assembly 200 is used to place keyboard; The pressure plate assembly 100 is independent of the carrier assembly 200. The pressure plate assembly 100 is provided with a test continuity component. The pressure plate assembly 100 is used to press against the keyboard placed on the carrier assembly 200 so that the test continuity component contacts the keyboard's circuit board cable and tests the continuity signal.

[0024] A gap is provided between the pressure plate assembly 100 and the carrier plate assembly 200 for placing the keyboard; the pressure plate assembly 100 is provided with a test continuity component; the pressure plate assembly 100 can move toward the carrier plate assembly 200 in a direction perpendicular to the carrier plate assembly 200 so that the test continuity component can contact the keyboard and test the continuity signal.

[0025] The carrier assembly 200 includes a board, and the pressure plate assembly also includes a board. Taking the board in the carrier assembly 200 as horizontally placed as an example, the board in the pressure plate assembly 100 is placed parallel to the board in the carrier assembly 200. One side of the carrier assembly 200 is used to place the keyboard. A gap is provided between the pressure plate assembly 100 and the carrier assembly 200. The keyboard is placed between the gap. The pressure plate assembly 100 is connected to a driving assembly. The driving assembly drives the pressure plate assembly 100 to move towards the carrier assembly 200 in a direction perpendicular to the carrier assembly 200, reducing the gap. The pressure plate assembly 100 presses against the keyboard. The pressure plate assembly 100 is provided with a test continuity component. When the pressure plate assembly 100 presses against the keyboard, the test continuity component moves closer to and contacts the keyboard at the detection position to test the keyboard's continuity signal.

[0026] Understandably, the carrier assembly 200 can be placed on a horizontal plane, and the pressure plate assembly 100 can be positioned above the horizontal plane away from the carrier assembly 200. The drive assembly drives the pressure plate assembly 100 to press down on the carrier assembly 200.

[0027] The carrier assembly 200 of this application is used to place the keyboard. Before testing, there is a gap between the pressure plate assembly 100 and the carrier assembly 200. After the keyboard is placed, it is pressed by the pressure plate assembly 100 for testing, which saves steps and improves work efficiency. Moreover, the pressure plate assembly 100 moves toward the carrier assembly 200 in a direction perpendicular to the carrier assembly 200, avoiding wear between devices. The vertical movement also facilitates the design and adjustment of the position of the test conduction component, so that the test conduction component can contact the keyboard and test the conduction signal. The positioning is accurate and the testing efficiency is high.

[0028] Understandably, the drive components can be linear motion cylinders, electric actuators, ball screw assemblies, etc.

[0029] Combination Figure 2 , Figure 3 As shown, in some embodiments, the pressure plate assembly 100 includes a pressure mold fixing plate 110 and a pressure plate fixing plate 120. The pressure mold fixing plate 110 is used to connect an external drive assembly. A buffer and a stop are provided between the pressure mold fixing plate 110 and the pressure plate fixing plate 120. The stop is installed on the pressure mold fixing plate 110 and / or the pressure plate fixing plate 120, and the buffer is installed on the pressure mold fixing plate 110 and / or the pressure plate fixing plate 120. The buffer is used to buffer the rigid force between the pressure mold fixing plate 110 and the pressure plate fixing plate 120, and the stop is used to prevent the pressure mold fixing plate 110 and the pressure plate fixing plate 120 from contacting each other.

[0030] Specifically, the buffer can be a spring, an elastic block, or other elastic structure, and the stop can be a column, shaft, rod, or other similar component. For example, the buffer can be a first spring 121, and the stop can be a first equalizing screw 122. The pressure plate assembly 100 includes a mold fixing plate 110 and a pressure plate fixing plate 120. The mold fixing plate 110 is used to connect an external drive assembly. A first spring 121 and a first equalizing screw 122 are disposed between the mold fixing plate 110 and the pressure plate fixing plate 120. The first equalizing screw 122 is installed on the mold fixing plate 110 and / or the pressure plate fixing plate 120. The resting length of the first spring 121 is greater than the length of the first equalizing screw 122.

[0031] The pressure mold fixing plate 110 and the pressure plate fixing plate 120 are connected by a first spring 121. A first equalizing screw 122 is installed on the pressure mold fixing plate 110 and / or the pressure plate fixing plate 120. The drive assembly drives the pressure mold fixing plate 110 to move. When the pressure mold fixing plate 110 moves toward the keyboard, the pressure plate fixing plate 120 also moves toward the keyboard. When the pressure plate fixing plate 120 reaches its limit position, the first spring 121 begins to contract. The drive assembly operates according to a preset extension and contraction length or extension and contraction time. However, when the first spring 121 contracts to the same length as the first equalizing screw 122, the first equalizing screw 122 prevents the pressure mold fixing plate 110 and the pressure plate fixing plate 120 from getting closer. The first equalizing screw 122 has the function of preventing overpressure. The first spring 121 buffers the downward impact force of the pressure plate assembly 100, reducing the rigid impact on the keyboard and preventing damage to the keyboard. Multiple sets of first springs 121 and first equal-height screws 122 are installed to ensure that the force in contact with the keyboard is uniform and to prevent the keyboard from being damaged.

[0032] A first cylindrical pin 111 is provided between the mold fixing plate 110 and the pressure plate fixing plate 120. The mold fixing plate 110 and the pressure plate fixing plate 120 are respectively provided with holes corresponding to the first cylindrical pin 111, which are used to accurately position the mold fixing plate 110 and the pressure plate fixing plate 120 relative to each other.

[0033] In some embodiments, the mold fixing plate 110 is provided with a through hole, and the through hole is provided with indexing pins 112 passing through both ends of the through hole. Two nuts are provided on the indexing pins 112. One nut is attached to the side of the mold fixing plate 110 away from the pressure plate fixing plate 120 and is attached to the other nut to lock them together. The pressure plate fixing plate 120 is provided with pin holes for the indexing pins 112 to pass through. The indexing pins 112 are used to position the relative positions of the through hole and the pin holes.

[0034] When assembling the mold fixing plate 110 and the pressure plate fixing plate 120, the indexing pin 112 is passed through the through hole and then through the pin hole. The center lines of the through hole and the pin hole are aligned with the center line of the indexing pin 112. The through hole is a threaded hole, and the threaded end of the indexing pin 112 engages with the through hole. Then, two nuts are tightened onto the indexing pin 112 from the side of the mold fixing plate 110 away from the pressure plate fixing plate 120. The two nuts can tighten against each other, thus fixing the indexing pin 112. When the pressure plate assembly 100 is not in operation, the unthreaded end of the indexing pin 112 is not inserted into the pin hole or is at least partially accommodated in the pin hole. When the mold fixing plate 110 and the pressure plate fixing plate 120 move closer or further apart, the relative offset between the mold fixing plate 110 and the pressure plate fixing plate 120 is limited.

[0035] Understandably, the indexing pins 112 are set at at least two positions on the die fixing plate 110 to better limit relative offset.

[0036] In some embodiments, the pressure plate fixing plate 120 is disposed on one side of the carrier plate assembly 200, and a grid pressure plate 130 is disposed on the side of the pressure plate fixing plate 120 near the carrier plate assembly 200. The grid pressure plate 130 is connected to the pressure plate fixing plate 120 by an elastic pin 134 and a connecting part 135. The grid pressure plate 130 is provided with a grid for avoiding the keys of the keyboard, and the grid pressure plate 130 is used to press the keyboard.

[0037] The grid pressure plate 130 is machined with an array of grid holes, the shape of which matches the keyboard keys to ensure that each key can be fully embedded in the grid holes for avoidance. The grid pressure plate 130 has through holes corresponding to the mounting connector 135. One end of the connector 135 passes through the through hole in the grid pressure plate 130, and the other end is threaded onto the elastic pin 134. The pressure plate fixing plate 120 has through holes for the elastic pin 134 to pass through. The elastic pin 134 is tightly fitted onto the pressure plate fixing plate 120, thus connecting the grid pressure plate 130 and the pressure plate fixing plate 120. The slight elasticity of the elastic pin 134 allows the grid pressure plate 130 to partially float during pressing, preventing hard contact that could scratch the keyboard surface.

[0038] In some embodiments, the test continuity component is installed on the side of the pressure plate fixing plate 120 near the carrier assembly 200. The test continuity component is used to correspond to the position of the keyboard circuit board cable and is used to press the keyboard circuit board cable in a straight line.

[0039] The test continuity component is mounted on the side of the pressure plate fixing plate 120 near the carrier board assembly 200, specifically in the edge area of ​​the pressure plate fixing plate 120, to avoid overlapping with the key area of ​​the mesh holes. Gold fingers are provided on the side of the test continuity component near the carrier board assembly 200. When the test continuity component approaches the keyboard, the gold fingers press against the keyboard's flexible ribbon cable on the carrier board to perform keyboard testing. The test continuity component is positioned to correspond to the keyboard's circuit board ribbon cable, and the number of gold fingers matches the number of test points on the keyboard's circuit board ribbon cable, ensuring precise contact between the test continuity component and the ribbon cable when the pressure plate fixing plate 120 moves.

[0040] The pressure plate fixing plate 120 is provided with multiple test continuity components for testing the circuit board wiring in different areas of the keyboard. For example, in this application, two test continuity components are used: a first test continuity component 141 and a second test continuity component 142.

[0041] Combination Figure 4 , Figure 5 As shown, specifically taking the first test continuity component 141 as an example, the first test continuity component 141 includes a fixing plate 1411 and an adapter plate 1412. One side of the fixing plate 1411 is installed on the pressure plate fixing plate 120. A second spring 1414 and a second equalizing screw 1413 are provided between the fixing plate 1411 and the pressure plate fixing plate 120. The second equalizing screw 1413 is installed on the fixing plate and / or the pressure plate fixing plate 120. The resting length of the second spring is greater than the length of the second equalizing screw. The second equalizing screw 1413 is also used to fix the adapter plate 1412 to the fixing plate 1411.

[0042] The adapter plate 1412 has gold fingers on the side away from the fixed plate 1411. The drive assembly operates according to preset extension and retraction lengths or extension and retraction times. Correspondingly, the fixed plate 1411 moves with the pressure plate fixed plate 120, and the adapter plate 1412 moves with the fixed plate 1411. When the gold fingers press against the keyboard, the second spring 1414 begins to contract. When the second spring 1414 contracts to the same length as the first equal-height screw 122, the second equal-height screw 1413 prevents the fixed plate 1411 from getting closer to the pressure plate fixed plate 120, and the second equal-height screw 1413 has the function of preventing overpressure. The second spring 1414 buffers the downward impact force of the pressure plate fixed plate 120, reduces the rigid impact of the adapter plate 1412 pressing against the keyboard circuit board cable, avoids excessive local pressure damaging the cable, and prevents damage to the keyboard. The use of multiple sets of second springs 1414 and second equal-height screws 1413 ensures that the force of the gold fingers contacting the keyboard is uniform, preventing damage to the keyboard circuit board cable.

[0043] An insulating pad 1415 is provided between the fixing plate 1411 and the adapter plate 1412. When the fixing plate 1411 is made of metal such as aluminum, the insulating pad 1415 has the function of preventing the adapter plate 1412 from short-circuiting.

[0044] The fixing plate 1411 and the adapter plate 1412 are positioned by a third cylindrical pin 1416. The third cylindrical pin 1416 passes through the through holes on the fixing plate 1411 and the adapter plate 1412 respectively, which are provided to ensure that the fixing plate 1411 and the adapter plate 1412 are installed accurately.

[0045] In some embodiments, the carrier assembly 200 includes a positioning structure for positioning the keyboard on the carrier assembly 200.

[0046] Specifically, in combination Figure 6 , Figure 7 As shown, the positioning structure includes a first positioning pin 211 and a second positioning pin 212. The first positioning pin 211 is used to insert into the positioning hole on the keyboard, and the second positioning pin 212 is used to abut against the edge of the keyboard and restrict the movement of the keyboard. The keyboard to be tested has multiple positioning holes. The first positioning pin 211 is used to insert into the positioning hole on the keyboard to position it. The end of the first positioning pin 211 away from the carrier assembly 200 is a rounded end to avoid rigid impact causing misalignment with the keyboard, and also to facilitate the insertion of the first positioning pin 211 into the positioning hole. Multiple first positioning pins 211 are provided on the carrier assembly 200. Multiple second positioning pins 212 are provided around the area on the carrier assembly 200 where the keyboard is placed. The edge of the keyboard abuts against the second positioning pins 212 to prevent the keyboard from moving on the carrier assembly 200.

[0047] Combination Figure 6 , Figure 7As shown, in some embodiments, the carrier plate assembly 200 and the pressure plate assembly 100 are positioned by a combination of multiple sets of locating pins of different sizes and multiple sets of bushings of different sizes that match the locating pins. The carrier plate assembly 200 is provided with a first bushing 221, a second bushing 222, a third bushing 223, and a fourth bushing 224. The dimensions of the first bushing 221, the second bushing 222, and the third bushing 223 increase sequentially, and they are located on the side of the carrier plate assembly 200 near the pressure plate assembly 100, within a through hole in the carrier plate assembly 200. The pressure plate assembly 100 is provided with a third locating pin 131 corresponding to the bushing, which is inserted into the first bushing 221; a fourth locating pin 132 corresponding to the bushing 222; and a sixth locating pin (not shown in the figure) corresponding to the bushing 223. The fourth bushing 224 is a waist-shaped bushing with an oblong or waist-shaped hole. While ensuring precise vertical guidance, it allows for a certain range of fine adjustments to compensate for assembly errors, component deformation, or workpiece positioning deviations. A seventh locating pin (not shown in the figure) is provided on the pressure plate assembly 100 corresponding to the fourth bushing 224. The carrier plate assembly 200 and the pressure plate assembly 100 achieve positioning through the interlocking of multiple sets of locating pins and multiple sets of bushings of different sizes that match the locating pins. This provides a foolproof function, ensures precise positioning, and prevents misalignment of the test conductive components due to movement or offset.

[0048] The fixing plate 1411 is also provided with a fifth positioning pin 1417, which can also be inserted into the first bushing 221 to ensure that the adapter plate 1412 contacts the keyboard circuit board cable accurately.

[0049] Combination Figure 6 , Figure 7 , Figure 8 As shown, in some embodiments, the carrier assembly 200 is provided with a test holder 230, and multiple test holders 230 can be provided. The test holder 230 is positioned on the carrier assembly 200 by a cylindrical pin and is installed on the carrier assembly 200 by screws, ensuring precise positioning and secure installation.

[0050] Specifically, the carrier assembly 200 of this application is provided with a first test socket 231 and a second test socket 232 corresponding to the first test conduction component 141 and the second test conduction component 142, respectively.

[0051] The test socket includes a base 2311 and an elastic element. The elastic element is mounted on the base 2311 and is used to hold the keyboard's circuit board cable. The elastic element can be a rubber block, silicone rod, or other elastic structure. The elastic deformation can prevent hard contact from damaging the cable.

[0052] Taking the first test socket 231 as an example, the first test socket 231 includes a base 2311 and a silicone rod 2312. The silicone rod 2312 is installed on the base 2311 and is used to place the keyboard's circuit board cable. The keyboard's circuit board cable is placed on the surface of the silicone rod 2312 away from the base 2311. During testing, the test conductive component presses against the cable, and the silicone rod 2312 generates elastic support force through deformation. This, combined with the test conductive component pressing the cable, prevents hard contact from damaging the cable.

[0053] In some embodiments, the test continuity component is provided with a connector for electrical connection with the aggregation adapter 143, and the test continuity component outputs a continuity signal through the aggregation adapter 143.

[0054] Specifically, the pressure plate assembly 100 is provided with multiple test continuity components, which are electrically connected to a converging adapter 143. The multiple test continuity components output continuity signals through the converging adapter 143. In the embodiments of this application, during testing, the continuity signals acquired by the first test continuity component 141 and the second test continuity component 142 are transmitted to the converging adapter 143 via wires. After signal conditioning, the signals are transmitted to external testing equipment, avoiding the wiring chaos caused by directly connecting multiple test continuity components to external equipment.

[0055] The first test continuity component 141 establishes conductivity by appropriately pressing the keyboard circuit board cable, thus eliminating the need for a flip-top assembly. Furthermore, the adapter board 1412 has a connector, allowing signals to be transferred to the aggregation adapter component 143 via a connecting cable, thereby saving the need for a probe module and an adapter board. These material savings reduce material costs and eliminate the maintenance expenses associated with these material savings.

[0056] The carrier plate assembly 200 of this application is also provided with a shim column 240. The shim column 240 is used to provide a gap between multiple carrier plate assemblies 200 when they are stacked, so as to avoid collision and wear between the multiple carrier plate assemblies 200.

[0057] The edge of the carrier assembly 200 of this application is also provided with anti-collision blocks 250. The anti-collision blocks 250 are installed on the edge of the carrier assembly 200 by mounting screws 251 to prevent the carrier assembly 200 on the conveyor line from colliding.

[0058] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
