[0062] In order to make the above-mentioned objects, features and advantages of the present invention more understandable, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from this description, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0063] like Figure 1-Figure 9 As shown, the present invention discloses an AP router PCB board tester, which includes: a bracket 201, on which a catching device 301 is installed, and the catching device 301 is provided with a catching claw 310, and the catching claw 310 is used to clamp the PCB sample and charge the PCB sample, and the catching device 301 is used to transfer the PCB sample;

[0064] The double-speed chain 101 is provided with an upper double-speed chain 110 and a lower double-speed chain 120. The upper double-speed chain 110 is provided with a collector rail 102. The double-speed chain 101 can be installed on the bracket 201. The upper double-speed chain 110 is used for forward transportation, and the lower double-speed chain 120 is used for reflux. The double-speed chain 101 generally has its own bracket. At this time, the bracket 201 is generally used to fix and install the catching device 301. The double-speed chain 101 needs to cooperate with the bracket 201, and then cooperate with the catching device 301, so that the catching device 301 can be clamped on the double-speed chain 101.

[0065] A tooling 144, wherein a first electrode sheet 145 and a second electrode sheet 146 are disposed at the bottom of the tooling 144, wherein the first electrode sheet 145 and the second electrode sheet 146 cooperate with and are electrically connected to the collector rail 102, and the tooling 144 is placed on the double-speed chain 101, and is transferred and supplied with electricity by the double-speed chain 101;

[0066] A carrier 140, the carrier 140 is used to fix the PCB and charge the PCB, the carrier 140 is installed on the tooling 144 and is electrically connected to the tooling 144;

[0067] A blocker 130, wherein the blocker 130 is installed on the double-speed chain 101, and the upper double-speed chain 110 is provided with the blocker 130, and the blocker 130 is used to block the tooling 144 and fix the tooling 144 in place;

[0068] A front return plate hoist 401, which is arranged at the front end of the double-speed chain 101, and is used to raise the height of the tooling 144 flowing out of the lower double-speed chain 120, and transfer the tooling 144 to the upper double-speed chain 110 after the height is raised;

[0069] A rear return plate hoist 410, which is arranged at the rear end of the double-speed chain 101, and which lowers the height of the tooling 144 that will flow out of the upper double-speed chain 110, and transfers the tooling 144 to the lower double-speed chain 120 after lowering the height;

[0070] The shielding box 501 is arranged around the bracket 201 or installed on the bracket 201. The shielding box 501 is used to detect whether the PCB is qualified. Generally, there are multiple shielding boxes 501, which are arranged around the bracket 201 or the capturing device 301.

[0071] It should be noted that, generally speaking, the front return plate elevator 401 is the starting point of the carrier 140 and the tooling 144, and the rear return plate elevator 410 is the turning point, which can be turned around as needed.

[0072] It should be noted that the catching device 301 is generally a mechanical arm, and the catching claw 310 is provided on the mechanical arm for clamping. The catching claw 310 clamps the PCB, charges the PCB and transfers the PCB by clamping the carrier 140. The catching claw 310 first energizes the carrier 140, and then clamps the carrier 140. When the carrier 140 is placed in the shielding box 501, the shielding box 501 energizes the carrier 140, and then disconnects the electrical connection between the catching claw 310 and the carrier 140, and then the catching claw 310 returns. The catching claw 310 generally first clamps the carrier 140 containing the tested PCB in the shielding box 501, and then places the carrier 140 containing the PCB to be tested into the shielding box 501. The shielding box 501, the catching device 301, and the front and rear return plate elevators are common existing technologies and will not be described in detail here. Figure 2 As shown, the shielding boxes 501 are arranged around the bracket 201, and there are 8 of them, and the shielding boxes 501 are arranged in an approximate circle. Generally speaking, the capturing device 301 is set at the center of the circle or approximate circle formed by each of the shielding boxes 501, so that the distance between the capturing device 301 and each of the shielding boxes 501 is roughly the same.

[0073] It should be pointed out that the tooling 144 is transferred from the upper speed chain 110 to the lower speed chain 120 through the front and rear return plate elevators, and then transferred from the lower speed chain 120 to the upper speed chain 110 after being transferred through the lower speed chain 120, thereby realizing a circulating flow on the speed chain 101.

[0074] Specifically, Figure 5 As shown, the catching claw 310 is provided with a front claw 320 and a rear claw 330 , and the front claw 320 and the rear claw 330 are used to clamp the PCB and charge the PCB. When in use, for example: the front claw 320 clamps the carrier 140 containing the PCB to be tested from the upper speed chain 110 and energizes the carrier 140, the carrier 140 charges the PCB to be tested, the rear claw 330 clamps the carrier 140 containing the tested PCB in the shielding box 501, and then the catching device 301 rotates and adjusts, the front claw 320 places the carrier 140 containing the PCB to be tested into the shielding box 501, after the shielding box 501 energizes the carrier 140, the power supply between the front claw 320 and the carrier 140 is disconnected, and the carrier 140 is released and placed, and the rear claw 330 places the carrier 140 containing the tested PCB back onto the upper speed chain 110, and the above process is repeated to realize the detection cycle of the PCB. The front claw 320 and the rear claw 330 are symmetrically arranged, and the structure is generally the same, and they realize the same function and can replace each other.

[0075] Specifically, Figure 8 As shown, the carrier 140 is provided with a catch ear 141, which is used to cooperate with the catching claw 310 for clamping, and the catch ear 141 can also be used as a power supply electrode. The catch ears 141 are generally provided with four, two in a group, and are respectively provided on both sides of the carrier 140. The front claw 320 and the rear claw 330 provided in the catching claw 310 are provided with a structure that cooperates with the catch ear 141. The carrier 140 is generally provided with a PCB charging terminal 142 to facilitate charging of the PCB.

[0076] Specifically, Figure 3As shown, a plurality of output electrodes 103 are arranged on the collector rail 102, and the output electrodes 103 are electrically connected to the first electrode sheet 145 and the second electrode sheet 146. The output electrodes 103 are generally arranged in a group of two on the left and right, and a linear array is arranged on the collector rail 102. Generally speaking, the upper surface of the output electrode 103 is arc-shaped, and the upper surface of the output electrode 103 is slidably matched with the first electrode sheet 145 and the second electrode sheet 146. The collector rail 102 is energized to the tooling 144, and then the carrier 140 is passed through the tooling 144, and finally the carrier 140 charges the PCB. When the tooling 144 flows on the upper speed chain 110, the carrier 140 can be energized at all times, and while the tooling 144, the carrier 140 and the PCB in the carrier 140 are conveniently transferred, the PCB is guaranteed to be charged at all times and will not lose power, so as to facilitate the completion of the subsequent testing work.

[0077] It should be pointed out that at least one blocker 130 is provided on the lower double-speed chain 120 to prevent the tooling 144 from being blocked at the front return plate elevator 401 when the tooling 144 is backflowing on the lower double-speed chain 120. The blocker 130 on the lower double-speed chain 120 blocks the backflowing tooling 144, waits for the front return plate elevator 401 to complete the lifting work of the previous tooling 144, and then releases the blocker 130 to transfer the current tooling 144 to the front return plate elevator 401. The lower double-speed chain 120 is generally provided with one blocker 130 near the front return plate elevator 401.

[0078] Specifically, Figure 6 , Figure 7As shown, the blocker 130 is provided with a mounting seat 131, and the mounting seat 131 is fixed on the speed chain 101. A blocker 132 is rotatably mounted on the mounting seat 131, and a torsion spring 135 is provided between the blocker 132 and the mounting seat 131, and the torsion spring 135 is used to reset the blocker 132. The blocker 130 is provided with a driving member 136, and the driving member 136 is generally a cylinder or a linear motor. A push rod 137 is provided on the driving member 136, and the driving member 136 drives the push rod 137 to move, and the push rod 137 drives the blocker 132 to rotate, and the blocker 132 is used to block the tooling 144. During operation, the torsion spring 135 makes the blocking member 132 stand upright and upward, so as to block the tooling 144. When the tooling 144 needs to move, the driving member 136 drives the push rod 137 to move, and the push rod 137 pushes the blocking member 132, so that the blocking member 132 rotates and compresses the torsion spring 135. After the rotation, the blocking member 132 no longer blocks the tooling 144, and the tooling 144 moves normally on the speed chain 101. When encountering the tooling 144 that needs to be blocked again, the driving member 136 retracts the push rod 137, and under the action of the torsion spring 135, the blocking member 132 is reset and blocks. Generally speaking, the lower end of the blocking member 132 is provided with a slot 133 that cooperates with the top end of the push rod 137; the upper end of the blocking member 132 is provided with a rotating wheel 134, and the rotating wheel 134 cooperates with the bottom surface of the tooling 144 to facilitate the movement of the tooling 144 above the blocking member 132.

[0079] Specifically, Figure 3As shown, generally speaking, at least five blockers 130 are arranged on the upper speed chain 110. From top to bottom, the first blocker 130 blocks the tooling 144 flowing out of the front return board elevator 401. At this time, the carrier 140 with the PCB to be tested is placed and installed on the tooling 144 blocked by the first blocker 130 through manual or mechanical clamping; the second blocker 130 blocks the flowing tooling 144 and waits for the catching device 301 to complete the process and clamping can be performed; the third blocker 130 blocks the flowing tooling 144, and then the catching device 301 stops the flowing tooling 144. The device 301 clamps the carrier 140 on the tooling 144, and the catching device 301 takes the clamped carrier 140 away and moves it to the shielding box 501, and then first clamps the carrier 140 with the tested PCB from the shielding box 501, and then places the carrier 140 with the PCB to be tested, and then the catching device 301 returns with the carrier 140 with the tested PCB; the third blocker 130 takes the carrier 140 on the catching device 301 After clamping, the tooling 144 is released, and the tooling 144 flows; the fourth blocker 130 blocks the tooling 144 flowing alone, and waits for the catching device 301 to bring back the carrier 140 with the tested PCB, and the carrier 140 is placed on the tooling 144, and then the fourth blocker 130 is released, and the tooling 144 flows; the fifth blocker 130 blocks the tooling 144 flowing out in front, and then performs manual or mechanical unloading, and the PCB with the tested PCB is placed on the carrier 140. The carrier 140 is taken out, and the fifth blocker 130 is released after being taken out; the tooling 144 flows into the rear return plate elevator 410 after waiting, and is transferred to the lower speed chain 120 through the action of the rear return plate elevator 410. The lower speed chain 120 transfers the tooling 144 to the front return plate elevator 401, and after waiting or directly entering the front return plate elevator 401, the front return plate elevator 401 sends the tooling 144 back to the upper speed chain 110, completing a cycle of the testing process.

[0080] It should be noted that, in the above process, the PCB to be tested is constantly charged through the capture device 301, the shielding box 501, and the carrier 140, so as to avoid power failure and re-processing. The carrier 140 is powered by the tooling 144 in cooperation with the speed chain 101. After the PCB is tested by the shielding box 501, the carrier 140 or PCB already has an OK or NG mark or identification information, which makes it easy for the NG or OK carrier 140 containing the tested PCB to be removed mechanically or manually at the fifth blocker 130 and classified.

[0081] In summary, the present invention connects the bracket 201, the double-speed chain 101, the tooling 144, the carrier 140, the blocker 130, the shielding box 501 and other components and devices through an ingenious structure, and cooperates with the structure set on the components to achieve the transfer and charging of the PCB on the double-speed chain, and the PCB can be kept charged when the catching device is used for transfer, so that the PCB is always powered on during the entire flow process, and the powered PCB can be conveniently transferred to the shielding box for testing, and the catching device places the PCB to be tested on the shielding box and clamps the tested PCB on the shielding box in one action, and then places the tested PCB back on the double-speed chain when returning to clamp, and the tooling can conveniently circulate and work in the entire process, and the PCB power failure that causes the process to be repeated is avoided in the entire process, thereby improving the detection efficiency and transfer efficiency of the PCB, and the transfer accuracy and reliability are high, which can effectively improve the PCB production efficiency and reduce the space occupied by the overall equipment, while reducing costs. The above greatly improves the practical value of the present invention.

[0082] The above-described embodiments only express one or more implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
