Description

Technical Field

[0001] This utility model relates to a testing device for a circuit board carrier device, and more particularly to a testing device for testing a circuit board clamping frame. Background Technology

[0002] In circuit board manufacturing, to facilitate the batch transfer of finished or semi-finished circuit boards, a circuit board carrier device is typically used for the batch transfer of multiple finished or semi-finished circuit boards. This circuit board carrier device usually includes a carrier frame and multiple circuit board clamping frames detachably housed within the carrier frame. Each circuit board clamping frame can be used to clamp one circuit board.

[0003] However, during use, the circuit board clamping frame may deform due to collisions or improper use, rendering it unable to stably clamp the circuit board. Therefore, each circuit board clamping frame should undergo structural deformation testing after a period of use to ensure that each frame can be used normally. Utility Model Content

[0004] The purpose of this invention is to provide a detection device that can be used to automatically and accurately detect the deformation of a circuit board clamping frame.

[0005] This invention relates to a testing device for inspecting circuit board clamping frames. The circuit board clamping frame has a quadrilateral frame and four hinges that can be driven to elastically swing and are pivotally mounted on the four side rods of the frame. The testing device includes a supporting mechanism, a plurality of first ranging sensors and a hinge detection mechanism disposed on the supporting mechanism, and a control device.

[0006] The support mechanism has a support platform for placing the circuit board clamping frame downwards along the side bars of the frame.

[0007] The first ranging sensors are spaced apart on the support platform and are distributed in pairs around the perimeter of the frame. The pairs of first ranging sensors can be controlled to perform horizontal ranging towards the two ends of the corresponding side bars to generate first ranging signals respectively.

[0008] The loose-leaf detection mechanism includes an adjustment module disposed on the carrier mechanism and a second ranging sensor mounted on the adjustment module and located above the carrier platform. The second ranging sensor can be driven by the adjustment module to move horizontally relative to the loose-leaf, and can be used to measure distances downwards to multiple positions on each loose-leaf to generate a second ranging signal respectively.

[0009] The control device is signal-connected to the first ranging sensor and the leaf detection mechanism. The control device includes a measurement control module and a deformation analysis module. The measurement control module controls the adjustment module to move the second ranging sensor. The deformation analysis module analyzes the first ranging signal to obtain the deformation of the frame, and analyzes the second ranging signal to obtain the deformation of each leaf.

[0010] The detection device for detecting circuit board clamping frames according to this utility model includes a support mechanism comprising multiple first object sensors mounted on the support platform for sensing the edge rods respectively. Each first object sensor generates a first object signal when it senses the corresponding edge rod resting against the support platform. The control device is also signal-connected to the first object sensors. When all the first object sensors generate the first object signal, the measurement control module controls the first distance sensor to perform distance measurement with the hinge detection mechanism.

[0011] The detection device for detecting circuit board clamping frames according to the present invention further includes a support base defining the support platform and a receiving module installed on the support base. The receiving module has multiple support members installed on the support platform and a support drive unit installed on the support base and connected to the support members. The support drive unit can be driven to drive the support members to change between a protruding position protruding from the support platform to cooperate in receiving the circuit board clamping frame and a downward position submerged in the support platform to release the received circuit board clamping frame from the submerged position on the support platform. When the support member changes to the protruding position, it can be used to push the circuit board clamping frame resting on the support platform upward away from the support platform.

[0012] The detection device for detecting circuit board clamping frames according to the present invention includes a bearing drive unit comprising a plurality of lifting drivers mounted on the bearing seat and respectively connected to the bearing member. Each lifting driver can be controlled to drive the corresponding bearing member to change between the protruding position and the submerged position.

[0013] The detection device for detecting circuit board clamping frames described in this utility model is suitable for use with a robotic arm for transferring the circuit board clamping frame. The detection device further includes a clamping mechanism, which includes a base, a clamping module pivotally mounted on the base, and a transmission module mounted on the base and connected to the clamping module. The transmission module can be controlled to drive the clamping module to pivot up and down between an upper swing position away from the support platform and a lower swing position close to the support platform. When the clamping module is in the upper swing position, it can be controlled to generate a clamping action for clamping the circuit board clamping frame transferred by the robotic arm, or to generate a release action for releasing the clamped circuit board clamping frame. When the clamping module is in the lower swing position, it can be controlled to generate a release action to release the clamped circuit board clamping frame onto the support member, or to generate a clamping action for clamping the circuit board clamping frame carried by the support member.

[0014] The present invention relates to a testing device for testing circuit board clamping frames. The clamping module includes a pivot seat pivotally mounted on the base and connected to the transmission module, four clamping drivers mounted on the pivot seat, and four clamping members respectively mounted on the clamping drivers. The pivot seat can be driven by the transmission module to change between the upper swing position and the lower swing position. The clamping drivers can be driven to transmit the clamping members to cooperate in producing a clamping action or a releasing action.

[0015] The detection device for detecting circuit board clamping frames according to the present invention further includes four second object sensors mounted on the pivot seat and corresponding to the clamping members. Each second object sensor can sense the frame in the direction of moving towards the corresponding clamping member to clamp the circuit board clamping frame, and can generate a second object signal when the frame is sensed. The control device is also signal-connected to the second object sensors. When the measurement control module determines that all the second object sensors have generated the second object signal, it can control the clamping driver to drive the clamping member to generate a clamping action.

[0016] The detection device for detecting circuit board clamping frames according to this utility model includes an adjustment module comprising two first transmission rails extending along a first direction and spaced parallel to each other along a second direction orthogonal to the first direction on the support platform, a second transmission rail spanning between the first transmission rails along the second direction, and a sliding seat disposed on the second transmission rail. The first transmission rails can be controlled to cooperate with the second transmission rails to move along the first direction, and the second transmission rails can be controlled to move the sliding seat along the second direction. The second distance sensor is mounted on the sliding seat.

[0017] The beneficial effects of this utility model are as follows: the control device can control the bearing mechanism, the first ranging sensor and the leaf detection mechanism to design the deformation measurement of the circuit board clamping frame, and can be used to automatically and accurately measure the deformation of the frame and the leaf of the circuit board clamping frame.

[0028] See Figure 1 , Figure 2 , Figure 3 This utility model discloses an embodiment of a testing device 200 for testing a circuit board clamping frame 9. It is suitable for use with a robotic arm (not shown) for transferring the circuit board clamping frame 9. The device can receive and test the circuit board clamping frame 9 transferred by the robotic arm, and transfer the tested circuit board clamping frame 9 back to the robotic arm. The circuit board clamping frame 9 includes a quadrilateral frame 91 with four side bars 911, and four hinges 92 respectively pivotally mounted on the side bars 911. Each hinge 92 can be driven to elastically flip and pivot relative to the frame 91, and can cooperate with the corresponding side bar 911 to clamp one side of a circuit board (not shown).

[0029] The detection device 200 includes a support mechanism 3, a clamping mechanism 4 mounted beside the support mechanism 3, a plurality of first ranging sensors 5 mounted on the support mechanism 3, a loose-leaf detection mechanism 6, and a control device 7. In implementation, the control device 7 is connected to the clamping mechanism 4, the first ranging sensors 5, and the loose-leaf detection mechanism 6 via wired communication technology and / or currently known wireless communication technology.

[0030] The support mechanism 3 includes a support base 31 defining an upward-facing support platform 310, and a receiving module 32 mounted on the support base 31 (e.g., Figure 4 As shown), and four first object sensors 33 disposed on the support platform 310. The support 31 has four limiting parts 312 protruding from the support platform 310 at intervals in the front, back, left and right, and the limiting parts 312 cooperate with the support platform 310 to define a limiting range 311 that can be used to accommodate and limit the circuit board clamping frame 9.

[0031] See Figure 2 , Figure 4 , Figure 5 , Figure 6 The receiving module 32 includes four support members 321 that are vertically and retractably embedded in the support platform 310, and a support drive unit 322 mounted on the support base 31 and connected to the support members 321. The support drive unit 322 has four lifting actuators 323 respectively connected to the support members 321. The lifting actuators 323 can be controlled to synchronously drive the vertical extension and retraction of the support members 321 relative to the support platform 310, and in an embedded position (e.g., ...) within the support platform 310. Figure 4 , Figure 6 As shown), and a protruding position extending outward from the support platform 310 (as shown). Figure 2 , Figure 5 (As shown) the changes between them.

[0032] When the support member 321 is in the protruding position, it can be used to cooperate in receiving the circuit board clamping frame 9 (e.g., from the clamping mechanism 4). Figure 5 As shown). When the support member 321 moves to the recessed position, the circuit board clamping frame 9 that it supports can be released from the support platform 310 (as shown). Figure 6 (As shown). When the support member 321 changes to the protruding position, it can be used to push the circuit board clamping frame 9, which is resting on the support platform 310, upward away from the support platform 310 (as shown). Figure 2 (As shown).

[0033] In this embodiment, the load-bearing drive unit 322 includes four lifting actuators 323 for respectively driving the load-bearing member 321. Each lifting actuator 323 is a telescopic cylinder mechanism. However, in another embodiment of this utility model, only one lifting actuator 323 may be used, coupled with a synchronous transmission mechanism connecting the lifting actuator 323 and the load-bearing member 321, to synchronously drive the vertical extension and retraction of the load-bearing member 321. Since there are many types of load-bearing drive units 322 used to drive the vertical extension and retraction of the load-bearing member 321, the implementation is not limited to the above embodiment.

[0034] See Figure 1 , Figure 2 The first object sensors 33 are distributed within the limiting interval 311, and are used to correspond to the side bars 911 of the frame 91 that rest against the support platform 310. Each first object sensor 33 can be used to sense whether the central section of the corresponding side bar 911 rests against the support platform 310, and will generate a first object signal when it senses that the side bar 911 rests against the support platform 310.

[0035] In this embodiment, the first object sensor 33 is a touch-type sensor embedded in and exposed on the support platform 310. It can be pressed and actuated by the central section of the side rod 911 placed on the support platform 310 to achieve the purpose of sensing the side rod 911. However, in other embodiments of this utility model, there are many types of first object sensors 33 that can be used to sense objects. For example, optical sensing technology can also be used for sensing. Therefore, in practice, the type of first object sensor 33 is not limited to the above embodiments.

[0036] See Figure 1 , Figure 5 , Figure 7 , Figure 8The clamping mechanism 4 includes a base 41 disposed on the side of the support 31, a clamping module 42 that can be pivotally mounted on the base 41, four second object sensors 44 mounted on the clamping module 42, and a transmission module 43 mounted on the base 41 and connected to the clamping module 42.

[0037] The clamping module 42 includes a pivot seat 421 pivotally connected to the top side of the base 41 and the transmission module 43 by its bottom edge, and a clamping unit 422 mounted on the pivot seat 421. The pivot seat 421 can be driven by the transmission module 43 to a generally upright, upward swing position away from the support platform 310 (e.g., Figure 1 As shown), and a generally horizontal lower edge position adjacent to the support platform 310 (as shown). Figure 5 As shown, the pivoting position 421 moves up and down, and the pivoting position 421 will synchronously drive the clamping unit 422 to move.

[0038] The clamping unit 422 can be controlled to clamp or release the circuit board clamping frame 9. In this embodiment, the clamping unit 422 includes four clamping drivers 423 spaced apart vertically and horizontally on the pivot seat 421, and four clamping members 424 respectively mounted on the clamping drivers 423. The clamping drivers 423 are telescopic cylinder mechanisms, which can transmit the displacement of the clamping members 424 relative to the pivot seat 421 by telescopic movement, thereby causing the clamping members 424 to cooperate in clamping the circuit board clamping frame 9 or releasing the circuit board clamping frame 9. The operation mode of the clamping unit 422 for clamping or releasing the circuit board clamping frame 9 will be explained later.

[0039] In this embodiment, the transmission module 43 is a telescopic cylinder mechanism, which can transmit the pivot seat 421 to pivot up and down relative to the base 41 through telescopic movement. However, in practice, since there are many ways to transmit the pivot seat 421 to pivot up and down relative to the base 41, the transmission module 43 is not limited to the above-described form.

[0040] The second object sensors 44 are respectively installed on the clamping members 424. Each second object sensor 44 can sense an object in the direction in which the corresponding clamping member 424 performs the clamping action, that is, sense whether the circuit board clamping frame 9 exists, and will generate a second object signal when the circuit board clamping frame 9 is sensed. In this embodiment, the second object sensor 44 is a light reflection sensor, but it is not limited to this in practice.

[0041] See Figure 1 , Figure 2In this embodiment, a total of eight first ranging sensors 5 are provided. The first ranging sensors 5 are disposed around the limiting interval 311, and are arranged in pairs around the circuit board clamping frame 9 supported by the bearing platform 310, corresponding to the side rods 911 respectively. The pairs of first ranging sensors 5 can be controlled to perform horizontal ranging towards the two ends of the corresponding side rods 911, generating a first ranging signal respectively. In this embodiment, the first ranging sensors 5 are laser rangefinders.

[0042] See Figure 1 , Figure 2 , Figure 9 The loose-leaf detection mechanism 6 includes an adjustment module 61 mounted on the support 31 and a second ranging sensor 62 disposed on the adjustment module 61. The adjustment module 61 includes two first transmission rails 611 parallel to each other on the support platform 310, a second transmission rail 612 spanning the first transmission rails 611, and a sliding seat 613 disposed on the second transmission rail 612. The second ranging sensor 62 is mounted on the sliding seat 613.

[0043] The first transmission track 611 extends back and forth along a first direction and is horizontally spaced left and right along a second direction orthogonal to the first direction. The second transmission track 612 extends left and right along the second direction and spans across the first transmission track 611. The first transmission track 611 can be controlled to drive the second transmission track 612 to move along the first direction. The second transmission track 612 can be controlled to drive the sliding seat 613 to move along the second direction. The second ranging sensor 62 can be controlled by the adjustment module 61 to move horizontally in two dimensions relative to the support platform 310.

[0044] The second ranging sensor 62 can be used to measure distances at multiple positions of each hinge 92 of the circuit board clamping frame 9 facing downwards, generating a second ranging signal for each position. In this embodiment, the second ranging sensor 62 is a laser rangefinder.

[0045] See Figure 1 , Figure 2 , Figure 3 The control device 7 can control the operation of the clamping module 42 and the transmission module 43 according to the sensing result of the second object sensor 44, and can also control the operation of the receiving module 32, the first ranging sensor 5 and the loose-leaf detection mechanism 6 according to the sensing result of the second object sensor 44.

[0046] The control device 7 includes a measurement control module 71 and a deformation analysis module 72. When a detection function is activated, the measurement control module 71 can control the operation of the support mechanism 3, the clamping mechanism 4, the first ranging sensor 5, and the leaf detection mechanism 6. The deformation analysis module 72 can receive and analyze the first ranging signal and the second ranging signal to obtain the deformation of the frame 91 and the leaf 92.

[0047] The following describes how the testing equipment 200 of this utility model is used to detect the deformation of the circuit board clamping frame 9.

[0048] The control device 7 is activated to perform the detection function, which in turn drives the measurement control module 71 to control the carrier 321 of the receiving module 32 to change to the protruding position, and controls the transmission module 43 to drive the pivot seat 421 to the upper swing position, and controls the second object sensor 44 to sense the circuit board clamping frame 9.

[0049] See Figure 3 , Figure 8 When the robotic arm moves the circuit board clamping frame 9 between the clamping members 424, placing the circuit board clamping frame 9 on the sensing path of the second object sensor 44, the measurement and control module 71, after analyzing and determining that the second object sensor 44 has generated the second object signal, controls the clamping driver 423 to drive the clamping members 424 to perform the clamping action, thereby clamping the frame 91 of the circuit board clamping frame 9. At this time, the robotic arm will be controlled to disengage from the circuit board clamping frame 9.

[0050] See Figure 2 , Figure 3 , Figure 5 Next, the measurement control module 71 controls the transmission module 43 to pivot the pivot seat 421 from the upper position to the lower position, causing the clamping unit 422 to move the clamped circuit board clamping frame 9 downwards to above the support platform 310, and placing the frame 91 of the circuit board clamping frame 9 on the support member 321. Then, the measurement control module 71 controls the clamping driver 423 to drive the clamping member 424 to perform the release action, releasing the circuit board clamping frame 9 and controlling the pivot seat 421 to return to the upper position.

[0051] See Figure 2 , Figure 3 , Figure 6Next, the measurement and control module 71 controls the load-bearing drive unit 322 to move the load-bearing member 321 to the submerged position, thereby releasing the circuit board clamping frame 9 from the limiting range 311 of the load-bearing platform 310. At this point, the setting and positioning of the circuit board clamping frame 9 to be tested is completed.

[0052] When the deformation of the frame 91 is less than a predetermined range, the side bars 911 of the frame 91 will press down and actuate the first object sensor 33. The first object sensor 33 will sense the actuation of the side bars 911 and generate the first object signal. When the deformation of the frame 91 is too large, such that one of the side bars 911 cannot press down and actuate the corresponding first object sensor 33, the first object sensor 33 will not generate the first object signal.

[0053] After the measurement and control module 71 controls the carrier 321 to release the circuit board clamping frame 9 from the carrier platform 310, if it analyzes and determines that one of the first object sensors 33 has not generated the first object signal, it will control the carrier drive unit 322 to drive the carrier 321 to the protruding position, thereby pushing the circuit board clamping frame 9 away from the carrier platform 310. It will also control the transmission module 43 to drive the pivot seat 421 to the lower position, and control the clamping driver 423 to drive the clamping member 424 to clamp the circuit board clamping frame 9 carried by the carrier 321. Then, the measurement and control module 71 will control the transmission module 43 to drive the pivot seat 421 to the upper position, and when the robotic arm clamps the circuit board clamping frame 9, it will control the clamping driver 423 to drive the clamping member 424 to release the circuit board clamping frame 9, so that the robotic arm can move the circuit board clamping frame 9, which has undergone excessive deformation, to the recycling point.

[0054] See Figure 3 , Figure 6 , Figure 9 After the measurement control module 71 controls the carrier 321 to release the circuit board clamping frame 9 onto the carrier platform 310, if it analyzes and determines that all the first object sensors 33 have generated the first object signal, it will control the first distance sensor 5 to measure the distance of the side rods 911 of the frame 91, so as to generate the first distance signal respectively. In addition, the measurement control module 71 will also control the adjustment module 61 to drive the second distance sensor 62 to move along the length direction of each flap 92, and control the second distance sensor 62 to perform distance sensing at multiple positions of each flap 92, so as to generate the second distance signal respectively.

[0055] The deformation analysis module 72 analyzes the distance value represented by each first ranging signal, and analyzes all the distance values ​​represented by the first ranging signals to determine the rectangularity of the frame 91, and further determines the deformation of the frame 91. The deformation analysis module 72 also analyzes the distance value represented by each second ranging signal corresponding to each leaf 92, and analyzes all the distance values ​​corresponding to each leaf 92 to obtain the horizontality of each leaf 92 in its length direction, thereby obtaining the deformation of the leaf 92.

[0056] After the measurement control module 71 controls the first ranging sensor 5 and the hinge detection mechanism 6 to complete the measurement action, it will, in accordance with the above-mentioned method of sending out the circuit board clamping frame 9 with excessive deformation, cause the clamping module 42 to move the measured circuit board clamping frame 9 away from the support platform 310 so that the robotic arm can take it away.

[0057] In summary, the structural design of the support mechanism 3, the first distance sensor 5, and the loose-leaf detection mechanism 6, along with the design of the control device 7 to control the support mechanism 3, the first distance sensor 5, and the loose-leaf detection mechanism 6 to measure the deformation of the circuit board clamping frame 9, can be used to automatically and accurately measure the deformation of the frame 91 and the loose-leaf 92 of the circuit board clamping frame 9.

[0058] Furthermore, the design of the first object sensor 33 installed on the support platform 310 can be used to sense the touch of the side rods 911 of the frame 91. This can be used to initially determine whether the deformation of the frame 91 is too large, and the circuit board clamping frame 9 with excessive deformation can be excluded first. Deformation analysis can only be performed on the circuit board clamping frame 9 with deformation within a reasonable range, which helps to avoid unnecessary measurements.

[0059] Furthermore, the structural design of the clamping mechanism 4 can be used to stably transfer the circuit board clamping frame 9 taken from the robotic arm to the support platform 310, and to remove the circuit board clamping frame 9 with excessive deformation or that has been inspected from the support platform 310 and hand it over to the robotic arm, so that the feeding and unloading of the circuit board clamping frame 9 to be inspected can be fully automated.

[0060] Therefore, the detection device 200 for the circuit board clamping frame 9 of this utility model is indeed a very innovative and convenient creation, and it can indeed achieve the purpose of this utility model.

[0061] The above description is merely an embodiment of this utility model and should not be construed as limiting the scope of this utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of this utility model shall still fall within the scope of this utility model.
