[0001] The utility model relates to the technical field of circuit board testing, in particular to a circuit board testing device. Background Art

[0002] Currently, circuit boards need to undergo ICT (In Circuit Tester, automatic online testing) after they are manufactured.

[0003] In related technologies, ICT equipment usually requires placing a circuit board on a tooling and positioning the tooling through a suction cup to complete the test. However, since the suction force of the suction cup is limited and it is easily affected by dust and other debris, the suction cup and the tooling need to be repeatedly adjusted, resulting in unsatisfactory positioning of the tooling, affecting production efficiency. Utility Model Content

[0004] The utility model aims at at least solving or improving the technical problem in the prior art that the production efficiency of a circuit board testing device is affected by positioning a tooling using a suction cup.

[0005] To this end, some embodiments of the present invention provide a circuit board testing device.

[0006] In view of this, the utility model proposes a circuit board testing device, comprising: a base; a detection needle plate assembly, which is arranged on the base, and the detection needle plate assembly includes a needle position; a tooling, which is detachably arranged on the base, the tooling is located on one side of the detection needle plate assembly and is opposite to the needle position, and the tooling is used to place the circuit board; a hook, which is movable relative to the detection needle plate assembly, and the hook and the tooling are detachably matched; a first driving assembly, which is connected to the hook, and the first driving assembly can drive the hook to move, and drive the tooling to move to a first target position, and when the tooling is at the first target position, the tooling and the needle position are offset.

[0007] The circuit board testing device proposed in the utility model comprises a base, a detection needle plate assembly, a tooling, a hook and a first driving assembly, wherein the detection needle plate assembly is arranged on the base, the detection needle plate assembly comprises a needle position, and the tooling is detachably arranged relative to the detection needle plate assembly and the base, wherein the first driving assembly is connected to the hook, thereby being able to drive the hook to move relative to the detection needle plate assembly.

[0008] Among them, a circuit board can be placed on the tooling. In order to improve the test efficiency, multiple circuit boards can be placed on the tooling at one time. After placing the circuit board on the tooling, the tooling can be placed on the base, and the tooling and the hook can be matched. After that, the first driving component is actuated to make the hook move, and finally the tooling and the needle position are abutted against each other. In addition, a circuit is arranged on the tooling to form an electrical connection between the circuit board and the needle position, thereby realizing the test of the circuit board.

[0009] Specifically, the tooling has a buckle that matches the hook. The tooling is placed on the base and the hook is hooked onto the buckle. Then the operator can control the first drive component to move the hook and drive the tooling to move on the base. After the tooling moves to the first target position, the tooling and the needle position are abutted against each other, and through the circuit on the tooling, electrical connection between each point on the circuit board and the needle position is achieved, and then the circuit board is tested.

Different tooling corresponds to different pin assemblies to ensure the matching of the positioning assembly and the tooling. The position detection assembly can detect the position of the tooling. When the position detection assembly detects that the tooling is not in the first target position, the second drive assembly is in a locked state, thereby ensuring that the second drive assembly can only be actuated when the tooling is in the first target position, thereby realizing the positioning of the tooling and the circuit board by the pin assembly, and reducing damage to the pin assembly, the tooling and the circuit board caused by misalignment.

[0022] Specifically, the tooling is placed on the base, and the hook is hooked onto the buckle. Then the operator can operate the control unit to enable the execution unit to drive the hook to move, and drive the tooling to move on the base. After the tooling moves to the first target position, the tooling and the needle position are offset, and then the second drive assembly can drive the ejector assembly to move, thereby achieving the positioning of the tooling and the circuit board.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0050] Refer to the following Figures 1 to 8 The circuit board testing device 100 provided according to some embodiments of the present invention is described.

[0051] According to some embodiments of the present invention, the present invention provides a circuit board testing device 100 , and the circuit board testing device 100 is used to perform an ICT test on a circuit board 300 .

[0052] like Figure 1 and Figure 2 As shown, the circuit board testing device 100 includes a base 110, a detection needle plate assembly 120, a tool 130, a hook 140 and a first driving assembly 150. The detection needle plate assembly 120 is arranged on the base 110, and the tool 130 is detachably arranged on the base 110. The upper surface of the base 110 is a plane, which is convenient for the detection needle plate assembly 120 and the tool 130 to cooperate. The detection needle plate assembly 120 includes a needle position 122.

[0053] The first driving assembly 150 is connected to the hook 140 , and the first driving assembly 150 can drive the hook 140 to move, and the hook 140 can drive the tooling 130 to move toward the detection needle plate assembly 120 , or move the tooling 130 away from the detection needle plate assembly.

[0054] The first driving assembly 150 can drive the hook 140 to move, so as to drive the tooling 130 to move to the first target position. When the tooling 130 is at the first target position, the tooling 130 and the needle position 122 are against each other.

[0055] Specifically, the tooling 130 has a mounting groove and a circuit. The mounting groove is used to place the circuit board 300 . When the tooling 130 is in the first target position, the circuit connects the circuit board 300 and the needle position 122 .

[0056] The circuit board testing device 100 provided by the utility model includes a base 110, a detection needle plate assembly 120, a tool 130, a hook 140 and a first driving assembly 150. The detection needle plate assembly 120 is arranged on the base 110, and the detection needle plate assembly 120 includes a needle position 122. The tool 130 is detachably arranged relative to the detection needle plate assembly 120 and the base 110, wherein the first driving assembly 150 and the hook 140 are connected, so that the hook 140 can be driven to move relative to the detection needle plate assembly 120.

[0057] Among them, a circuit board 300 can be placed on the tooling 130. In order to improve the test efficiency, multiple circuit boards 300 can be placed on the tooling 130 at one time. After placing the circuit board 300 on the tooling 130, the tooling 130 can be placed on the base 110, and the tooling 130 and the hook 140 are matched. Then, the first driving component 150 is actuated to make the hook 140 move, and finally the tooling 130 and the needle position 122 are abutted against each other. In addition, a circuit is arranged on the tooling 130, so that the circuit board 300 and the needle position 122 are electrically connected, thereby realizing the test of the circuit board 300.

[0058] Specifically, the tooling 130 has a buckle that matches the hook 140. The tooling 130 is placed on the base 110, and the hook 140 hooks the buckle. Then the operator can control the first driving assembly 150 to move, so that the hook 140 moves, driving the tooling 130 to move on the base 110, such as Figure 3 As shown, the tooling 130 moves along the BA direction. After the tooling 130 moves to the first target position, the tooling 130 and the needle position 122 are abutted against each other, and through the circuit on the tooling 130, electrical connection is achieved between each point on the circuit board 300 and the needle position 122, and then the circuit board 300 is tested.

[0059] After the test is completed, the operator can control the first driving assembly 150 to move, so that the hook 140 moves, driving the tooling 130 to move on the base 110, and when the tooling 130 leaves the first target position, Figure 3 As shown, the tooling 130 moves along the AB direction, so as to facilitate the disassembly and assembly of the tooling 130, and also facilitate the placement and taking of the circuit board 300 on the tooling 130, and facilitate the replacement of the tooling 130. The production changeover is simple and easy to operate. The circuit board testing device 100 provided by the utility model can save time significantly in the case of frequent production changes.

[0060] As described above, the tooling 130 is driven to move by the buckle, so that the movement of the tooling 130 is more stable, the positioning reliability of the tooling 130 is improved, and the production efficiency is improved.

[0061] The utility model drives the hook 140 to move through the first driving assembly 150 to achieve pushing and pulling of the tooling 130. Compared with the suction cup, the hook 140 drives the tooling 130 to move and position more reliably.

[0062] Optionally, the detection needle plate assembly 120 is erected on the base 110 , and the needle position 122 of the detection needle plate assembly 120 is located on the peripheral side of the detection needle plate assembly 120 . When the tooling 130 is located at the first target position, the needle position 122 faces the tooling 130 .

[0063] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, there are multiple hooks 140, and the multiple hooks 140 cooperate with the tooling 130, wherein the number of the hooks 140 is two, three, four or five, etc.

[0064] like Figure 8 As shown, in some embodiments, optionally, the detection needle plate assembly 120 includes a through hole, and the hook 140 is disposed in the through hole of the detection needle plate assembly 120 .

Among them, the ejector assembly 160 and the second driving assembly 170 are detachably matched.

[0066] Among them, when the position detection component 180 detects that the tooling 130 is not in the first target position, the second drive component 170 is in a locked state, thereby achieving an anti-foolproof effect. When the position detection component 180 detects that the tooling 130 is in the first target position, the second drive component 170 can operate.

[0067] In this embodiment, the circuit board testing device 100 further includes an ejector assembly 160, a second drive assembly 170 and a position detection assembly 180. The ejector assembly 160 is arranged above the base 110, and the ejector assembly 160 can move relative to the base 110. The second drive assembly 170 and the ejector assembly 160 can be detachably matched, so that the tooling 130 and the ejector assembly 160 can form a combination. Different tools 130 correspond to different ejector assemblies 160 to ensure the matching of the positioning assembly and the tooling 130. The position detection assembly 180 can detect the position of the tooling 130. When the position detection assembly 180 detects that the tooling 130 is not in the first target position, the second drive assembly 170 is in a locked state, thereby ensuring that the second drive assembly 170 can only move when the tooling 130 is in the first target position, so as to realize the positioning of the tooling 130 and the circuit board 300 by the ejector assembly 160, and reduce the damage of the ejector assembly 160, the tooling 130 and the circuit board 300 caused by misalignment.

[0068] Furthermore, the tooling 130 and the ejector assembly 160 are both detachable components, and therefore can be designed accordingly for different circuit boards 300 to be tested, so that one circuit board testing device 100 can be used for testing a variety of circuit boards 300 .

[0069] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the circuit board testing device 100 also includes a bracket 190 and a main body 200, the bracket 190 is arranged on the peripheral side of the base 110, the position detection component 180 is arranged on the bracket 190, the main body 200 is arranged on the bracket 190 and is located above the base 110, when the tooling 130 is installed on the base 110, the tooling 130 is located between the main body 200 and the base 110, and the second driving component 170 is arranged on the main body 200.

[0070] In this embodiment, the circuit board testing device 100 also includes a bracket 190 and a main body 200. The main body 200 is arranged on the bracket 190, so that the main body 200 is supported by the bracket 190. The bracket 190 is arranged on the peripheral side of the base 110. The position detection component 180 is arranged on the bracket 190, so as to facilitate the detection of the position of the tooling 130. The second driving component 170 is arranged on the main body 200, and when the tooling 130 is installed on the base 110, the tooling 130 is located between the main body 200 and the base 110, so as to facilitate the positioning of the tooling 130 and the circuit board 300 by the ejector assembly 160.

[0071] Specifically, the position detection assembly 180 detects the position of the tool 130. When the tool 130 is at the first target position, the second drive assembly 170 is actuated to move the ejector assembly 160 downward to press the tool 130 and the circuit board 300 to complete the test. The ejector assembly 160 can be used to press the tool 130 and the circuit board 300, and can also be used to test the circuit board 300.

[0072] Among them, the position detection component 180 can be a grating structure, and the tooling 130 is designed to have a specific height so that the tooling 130 can cooperate with the grating structure, thereby achieving autonomous anti-mistake when the tooling 130 is not in the first target position, effectively reducing the possibility of damage to the tooling 130.

[0074] In this embodiment, the second driving assembly 170 includes a telescopic member 172, a mounting member 174 and a positioning pin 176. The telescopic member 172 is arranged on the main body 200, and the mounting member 174 is connected to the telescopic member 172. When the telescopic member 172 is extended, the mounting member 174 is driven to approach the base 110. When the telescopic member 172 is shortened, the mounting member 174 is driven away from the base 110. The ejector assembly 160 is detachably arranged on the mounting member 174, and a positioning pin 176 is arranged on the mounting member 174. The positioning pin 176 is movable relative to the mounting member 174. When the ejector assembly 160 is installed on the mounting member 174 and is in the second target position, the positioning pin 176 can be embedded in the ejector assembly 160 to position the ejector assembly 160, thereby ensuring the positioning accuracy between the ejector assembly 160 and the tooling 130.

[0075] Specifically, the mounting member 174 includes a mounting slot, and the ejector assembly 160 can be inserted into the mounting slot. The ejector assembly 160 includes a positioning hole. When the ejector assembly 160 is installed to the second target position, the positioning hole and the positioning pin 176 are opposite to each other. At this time, the positioning pin 176 can be moved so that the positioning pin 176 is embedded in the positioning hole. When the ejector assembly 160 needs to be removed, the positioning pin 176 can be moved first to disengage the positioning pin 176 from the positioning hole, and then the ejector assembly 160 can be removed. The positioning pin 176 can be moved in a manner of screwing in and out, thereby facilitating the operation of the positioning pin 176.

[0076] like Figure 6 and Figure 7 As shown, in some embodiments, optionally, the first driving component 150 includes an actuator 152 and a control unit 154.

The control unit 154 is set on the base 110, the bracket 190, the main body 200 or the second drive component 170, so as to facilitate the operation of the control unit 154.

[0079] Specifically, the tooling 130 is placed on the base 110, and the hook 140 is hooked onto the buckle. Then the operator can operate the control unit 154, so that the execution unit 152 drives the hook 140 to move, and drives the tooling 130 to move on the base 110. After the tooling 130 moves to the first target position, the tooling 130 and the needle position 122 are abutted against each other, and then the second drive assembly 170 can drive the ejector assembly 160 to move, thereby realizing the positioning of the tooling 130 and the circuit board 300.

[0080] Optionally, there are multiple executing parts 152 , and one executing part 152 is connected to one hook 140 , wherein the number of the executing parts 152 is two, three, four or five, etc., so as to increase the force of the push-pull tooling 130 .

[0081] The control unit 154 includes a gear lever. When the gear lever is in the first gear position, the execution unit 152 is extended. When the gear lever is in the second gear position, the execution unit 152 is shortened, thereby realizing one-touch control of the state of the execution unit 152.

[0082] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the control part 154 is disposed on the mounting member 174 , and there are multiple positioning pins 176 , and the multiple positioning pins 176 are respectively located on both sides of the control part 154 .

[0083] In this embodiment, the control part 154 is arranged on the mounting part 174, that is, the control part 154 is above the base 110, so as to facilitate the operator to operate the control part 154, and there are multiple positioning pins 176, and the multiple positioning pins 176 are respectively located on both sides of the control part 154, so that the positioning of the ejector assembly 160 by the multiple positioning pins 176 can improve the positioning effect of the ejector assembly 160.

[0084] like Figure 7 As shown, in some embodiments, optionally, the actuator 152 is a pneumatic actuator, and the first drive assembly 150 also includes an air duct 156, which connects the actuator 152 and the air source 400, and the control unit 154 is used to adjust the on / off state of the air duct 156 to control the state of the actuator 152.

[0085] In this embodiment, the actuator 152 is a pneumatic actuator, and the first drive component 150 also includes an air duct 156, which connects the actuator 152 and the air source 400. The control unit 154 can adjust the on / off state of the air duct 156, thereby achieving control over the state of the actuator 152. The pneumatic actuator has a reliable activity effect, low cost, and no risk of oil leakage.

[0086] Specifically, the control unit 154 can extend or shorten the execution unit 152 by adjusting the on / off state of the airway tube 156 .

[0087] The actuator 152 may be a cylinder, and the force of the push-pull tooling 130 may be increased by adjusting the cylinder diameter of the actuator 152 .

[0088] The gas source 400 may be an air pump or the like.

[0089] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the circuit board testing device 100 further includes a first guide member 210 disposed on the detection needle plate assembly 120, the tooling 130 includes a second guide member 132, and the first guide member 210 and the second guide member 132 are adapted to each other.

[0090] In this embodiment, the circuit board testing device 100 further includes a first guide member 210 disposed on the detection needle plate assembly 120 , and the tooling 130 includes a second guide member 132 . The first guide member 210 and the second guide member 132 are adapted to each other, thereby ensuring the movable path of the tooling 130 .

[0091] Specifically, the tooling 130 is placed on the base 110, and the hook 140 hooks the buckle. At this time, the first guide member 210 and the second guide member 132 correspond to each other. Then the operator can operate the first driving assembly 150 to make the hook 140 drive the tooling 130 to move along the guide path of the first guide member 210 and the second guide member 132 on the base 110. After the tooling 130 moves to the first target position, the tooling 130 and the needle position 122 are against each other.

[0092] Among them, one of the first guide member 210 and the second guide member 132 is a guide column, and the other is a guide hole. The modified guiding method is reliable and low in cost.

[0093] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the circuit board testing device 100 further includes a limit assembly 220 disposed on the detection needle plate assembly 120, and when the hook 140 is in the first target position, the tooling 130 and the limit assembly 220 and the needle position 122 are offset against each other.

[0094] In this embodiment, the circuit board testing device 100 further includes a limit assembly 220 disposed on the detection needle plate assembly 120 . When the hook 140 is at the first target position, the tooling 130 , the limit assembly 220 and the needle position 122 abut against each other.

[0095] Specifically, the tooling 130 is placed on the base 110, and the hook 140 hooks the buckle. Then the operator can operate the first driving assembly 150 to make the hook 140 drive the tooling 130 to move on the base 110. After the tooling 130 moves to the first target position, the tooling 130 and the needle position 122 are against each other, and the tooling 130 also against the limit assembly 220, thereby reducing the possibility of damage to the tooling 130 and the detection needle plate assembly 120.

[0096] like Figure 4 , Figure 5 and Figure 8 As shown, in some embodiments, optionally, the number of needle positions 122 is at least 1000.

[0097] In this embodiment, the detection needle board assembly 120 includes at least 1000 needle positions 122, thereby increasing the number of circuit boards 300 tested each time and improving production efficiency.

[0098] Furthermore, the arrangement of at least 1000 needle positions 122 , in conjunction with the first driving assembly 150 and the hook 140 , can increase the fitting effect between the tooling 130 and the detection needle plate assembly 120 .

[0099] Specifically, the operation of the circuit board testing device 100 provided by the utility model is as follows: after the operator takes the tooling 130, he places it and the hook 140 on the base 110 accordingly, so that the hook 140 is embedded in the tooling 130, and then puts the ejector assembly 160 corresponding to the tooling 130 into the second drive assembly 170. The operator operates the control unit 154, and after the tooling 130 moves to the first target position, the ejector assembly 160 can be pressed down, and then the test is completed. If the tooling 130 is not in the first target position, the second drive assembly 170 cannot move, and the ejector assembly 160 cannot be pressed down, thereby realizing autonomous anti-foolproofing and reducing the possibility of damage to the tooling 130 and the ejector assembly 160.
