Description

Technical Field

[0001] The utility model relates to the technical field of electronic detection, in particular to a flexible circuit board detection mechanism. Background Art

[0002] In the current field of electronic manufacturing, especially in the electrical testing process of flexible printed circuit boards (FPCs), a thorny problem frequently encountered is closely related to foreign objects on the product surface. These tiny impurities, such as dust and fibers, inadvertently adhere to the surface of the circuit board during the production process and become an invisible killer affecting product quality and production efficiency. Specifically, when a flexible circuit board contaminated with foreign objects enters the high-precision electrical testing link, these seemingly insignificant foreign substances can cause significant damage. They may be squeezed into the contact points between the circuit board and the test fixture under high voltage, resulting in physical damage to the product surface, namely the so-called "crushing injury". Such crushing injuries not only directly affect the electrical performance of the circuit board but may also cause the entire component to malfunction severely, leading to product scrapping.

[0003] Even more seriously, after coming into contact with the probes in the precision fixture, foreign objects often cause abnormal deformation of the probes, such as bending or breaking. This not only increases the replacement frequency of the probes but also forces the production line to be frequently interrupted for fixture maintenance and probe replacement, seriously dragging down the overall production progress. The frequent damage of the probes not only increases production costs but also reduces production efficiency, becoming a major bottleneck restricting the efficient operation of enterprises.

[0004] In view of the above challenges, there is an urgent need for a new solution to effectively remove foreign objects on the surface of flexible circuit boards, reduce or even eliminate the crushing injuries caused by foreign objects, while ensuring the service life and testing accuracy of the test probes, thereby improving the overall production quality and efficiency.

[0040] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0041] In the present utility model, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms do not limit the present utility model.

[0042] In order to solve the problem that foreign objects on the surface damage the circuit board in the electrical test process of the flexible printed circuit board. The present utility model provides a new flexible circuit board detection mechanism.

[0043] As Figure 1-7 shown, a flexible circuit board detection mechanism provided by an embodiment of the present utility model includes a cleaning device 1, an electrical test device, and a loading and unloading manipulator 5.

[0044] Among them, the cleaning device 1 includes a conveyor belt 11 and a cleaning unit 12.

[0045] Specifically, the conveyor belt 11 has a to-be-cleaned station 1111 and a post-cleaning station 1121, and the conveyor belt 11 is arranged to convey products from the to-be-cleaned station 1111 to the post-cleaning station 1121.

[0046] The cleaning unit 12 is disposed between the to-be-cleaned station 1111 and the post-cleaning station 1121. The cleaning unit 12 includes two dust removal rollers 121 arranged oppositely and at least one sticky dust roller 122 corresponding to each dust removal roller. A space for the product to pass through is defined between the two dust removal rollers 121. When the product passes through the space, the dust removal rollers 121 can roll on the surface of the product to remove foreign matters on the product, and the sticky dust roller 122 can be in circumferential rolling contact with or separated from the corresponding dust removal roller 121.

[0047] It should be noted that in the present utility model, the dust removal rollers 121 are usually set as rollers made of silica gel material, and the dust removal rollers 121 can effectively remove dust on the product. And when the product passes through the space defined by the two dust removal rollers 121, the two dust removal rollers 121 are in rolling contact with the product, that is, the two dust removal rollers 121 can roll on the product passing through the space, and thus dust, foreign matters, etc. on the product can be removed.

[0048] Through the above settings, when the product passes through the space defined by the two dust removal rollers 121, the dust removal rollers 121 can remove dust and foreign matters on the product, and the sticky dust roller 122 can be in rolling contact with the dust removal roller 121 to take away the foreign matters on the dust removal roller 121. During the shutdown of the equipment, the sticky dust roller 122 can be separated from the corresponding dust removal roller 121 to avoid the formation of residual glue on the dust removal roller 121 due to long-term adhesion between the two, resulting in the pollution of the product by the residual glue.

[0049] Optionally, the sticky dust roller 122 can be formed by winding sticky dust paper; and the sticky dust paper on the circumference of the sticky dust roller 122 can be removed in sections. Therefore, when cleaning the dust removal roller 121, the contaminated sticky dust paper on the circumference of the sticky dust roller 122 can be removed regularly, so as to ensure the cleanliness of the circumference of the dust removal roller 121.

[0050] The present utility model includes an electrical testing device (not shown in the figure) and a loading and unloading robot 5. The loading and unloading robot 5 is at least used to transfer the product on the post-cleaning station 1121 into the electrical testing device.

[0051] It should be noted that in this embodiment, the electrical testing device can be used to detect the electrical characteristics of the product; for example, open circuit (Open) and short circuit (Short) detection, resistance measurement, capacitance and inductance measurement, etc.

[0052] Among them, the open circuit (Open) and short circuit (Short) detection mainly includes: checking whether there are any undue open circuits or short circuits in the conductive paths on the PCB to ensure that the electrical connections between various components are correct.

[0053] The resistance measurement mainly includes: measuring the resistance value in the circuit, verifying whether the resistance value of the component meets the design requirements, and checking whether there are abnormal changes in the resistance after soldering.

[0054] The capacitance and inductance measurement mainly includes: measuring the capacitance and inductance components in the circuit to ensure that their values fall within the expected tolerance range.

[0055] Generally speaking, the electrical measurement device includes a device body and a loading table arranged inside the device body. When detecting a product, the product can be placed on the loading table.

[0056] In this embodiment, a positioning unit 6 is arranged on the post-cleaning station 1121. The positioning unit 6 is used to obtain the offset information of the product on the post-cleaning station 1121 relative to the loading and unloading manipulator 5, so as to control the loading and unloading manipulator 5 to adjust its own position according to the offset information, and then place the product on the post-cleaning station onto the loading table.

[0057] It can be understood that the setting of the positioning unit 6 can help the loading and unloading manipulator 5 to position more accurately, and grasp the product at a suitable angle for transfer.

[0058] Specifically, the positioning unit 6 obtains the offset information of the product on the post-cleaning station 1121 relative to the loading and unloading manipulator 5. The loading and unloading manipulator 5 adjusts its own position according to this offset information so that the loading and unloading manipulator 5 can grasp the product more precisely. After the loading and unloading manipulator 5 grasps the product, it adjusts its own position again according to the aforementioned offset information, and then sends the product to the loading table inside the electrical measurement device. The setting of the positioning unit 6 helps to correct the position deviation of the loading and unloading manipulator 5 and enables it to transfer the product more precisely.

[0059] Further, as shown in Figure 2-4 the conveyor belt 11 includes a first section 111 and a second section 112 that can be independently conveyed. The station to be cleaned 1111 is located on the first section 111, and the post-cleaning station 1121 is located on the second section 112. The two dust removal rollers 121 include a first dust removal roller 1211 arranged between the first section 111 and the second section 112 and a second dust removal roller 1212 located above the first dust removal roller 1211. The first section 111, the second section 112 and the first dust removal roller 1211 are docked to support the product.

[0060] With such a setting, it can be ensured that the product can run smoothly when being transported on the first section 111, the first dust removal roller 1211 and the second section 112.

[0061] Further, the cleaning device 1 includes a driving unit for driving the at least one dust-sticking roller to move towards or away from the corresponding dust-removing roller. The driving unit includes driving members provided at both ends of the dust-sticking roller and a mounting seat connected to the driving part of the driving member. Both ends of the dust-sticking roller are provided on the two mounting seats.

[0062] Corresponding to this embodiment, referring to Figure 3-4 , corresponding to the first dust-removing roller 1211 is a first dust-sticking roller 1221. Two driving members 133 are provided on both sides of the first dust-sticking roller 1221. A first mounting seat 131 is connected to the driving part of the driving member 133.

[0063] Specifically, referring to Figure 3 , as shown in the best view of 5, the first mounting seat 131 includes a first fixing seat 1311. The first fixing seat 1311 is connected to the driving part of a driving member 133. A concave support groove 1312 is provided on the upper end surface of the first fixing seat 1311. Both ends of the first dust-sticking roller 1211 are respectively inserted into the concave support groove 1312 through connecting members. This setting can facilitate the disassembly of the first dust-sticking roller 1221.

[0064] Further, still referring to Figure 3-4 shown, corresponding to the second dust-removing roller 1212 is a second dust-sticking roller 1222. Two driving members 134 are provided on both sides of the second dust-sticking roller 1222. A second mounting seat 132 is connected to the driving part of the driving member 134, that is, both ends of the second dust-sticking roller 1222 are connected to the two second mounting seats 132.

[0065] Then referring to Figure 3 and Figure 6 shown, the second mounting seat 132 includes a second fixing seat 1321 and a bearing 1323. The second fixing seat 1321 is connected to the driving part of the driving member 134. A slot 1322 for inserting the bearing is provided on the second fixing seat 1321. Both ends of the second dust-sticking roller 1222 are respectively inserted into the bearing 1323 through connecting members.

[0066] With this setting, the second dust-sticking roller 1222 can pivot well relative to the second fixing seat 1321, and the setting of the slot 1322 can enable the bearing 1323 to be quickly inserted and matched with the second fixing seat 1321, facilitating the user to install or disassemble.

[0067] It can be understood that when the two driving members 134 move, their driving parts can drive the second fixing seat 1321 to move toward or away from the second dust removal roller 1212, and then drive the second dust sticking roller 1222 to move toward or away from the second dust removal roller 1212.

[0068] In this embodiment, optionally, the driving members 133 and 134 are generally configured as cylinders, and the driving part is configured as a piston rod of the cylinder.

[0069] Optionally, the first mounting seat 131 further includes a connecting component connecting the first fixed seat 1311 and the piston rod, and the connecting component is slidably arranged on the cylinder body of the cylinder. When the piston rod of the cylinder is driven to move, the connecting component is driven to slide on the cylinder body of the cylinder, thereby driving the first fixed seat 1311 connected to the connecting component to move. Such an arrangement can ensure that the first fixed seat 1311 has good stability when moving, avoiding the shaking that locally applies force to the first dust removal roller 1211, resulting in stains on the first dust removal roller 1211.

[0070] Preferably, in this embodiment, the cleaning device further comprises a pivot drive unit corresponding to each dust removal roller, and the pivot drive unit is used to drive the corresponding dust removal roller to pivot, so as to ensure that the dust removal roller rolls on the surface of the product to remove foreign matter on the surface of the product.

[0071] Furthermore, the pivot drive unit comprises two pivot drive members arranged at two ends of the corresponding dust removal roller, and the pivot drive members are arranged as pivot motors. The driving part of the pivot motor is in transmission cooperation with the dust removal roller.

[0072] Specifically, in the utility model, the first dust removal roller 1211 is connected on both sides with a pivot driving member (not shown in the figure) for driving the first dust removal roller 1211 to pivot. The upper surface of the first dust removal roller 1211 has a first tangent parallel to the direction from the first section 111 to the second section 112. The pivot driving member can drive the first dust removal roller 1211 to pivot along the first tangent, thereby causing the product located on the upper surface of the first dust removal roller 1211 to move in the direction from the first section 111 to the second section 112.

[0073] Correspondingly, pivot drive members (not shown in the figure) for driving the second dust removal roller 1212 to pivot are connected to both sides of the second dust removal roller 1212. The lower surface of the second dust removal roller 1212 has a second tangent line parallel to the direction from the first section 111 to the second section 112. When the product passes through the space, the second dust removal roller 1212 can roll on the surface of the product to remove foreign objects on the product, and the pivot drive member can drive the second dust removal roller 1212 to pivot along the second tangent line, so as to assist the product to move in the direction from the first section 111 to the second section 112.

[0074] Then return Figure 1 As shown, a flexible circuit board detection mechanism provided in this embodiment further includes a product to-be-tested station 2 and a cleaning and picking unit 3. The product to-be-tested station 2 is used to place the product to be measured. Generally, the product to-be-tested station 2 is located on an adjacent or nearby conveying device, and after the product completes the previous process, it will be conveyed to the product to-be-tested station 2 for waiting.

[0075] The cleaning and picking unit 3 is at least used to move the product on the product to-be-tested station 2 to the to-be-cleaned station 1111. In a specific operation process, the cleaning and picking unit 3 can often be a moving manipulator or a transfer conveyor, etc. The product on the product to-be-tested station 2 can be transferred to the to-be-cleaned station 1111 through the cleaning and picking unit 3.

[0076] Then, the product is cleaned by the cleaning unit 12, and the cleaned product moves to the post-cleaning station 1121 for waiting for detection.

[0077] As a preferred implementation manner, referring to Figure 7 As shown, the loading and unloading manipulator 5 includes a moving arm 51, a flipping unit 52, and an adsorption unit 53. The moving arm 51 is connected to the adsorption unit 53 through the flipping unit 52. The adsorption unit 53 has a first mounting surface 531 and a second mounting surface 532 arranged back to back. A plurality of first adsorbing members 5311 for adsorbing the product are provided on the first mounting surface 531, and a plurality of second adsorbing members 5321 for adsorbing the product are provided on the second mounting surface 532. The flipping unit 52 is used to drive the adsorption unit 53 so that the first mounting surface 531 or the second mounting surface 532 of the adsorption unit faces the product on the post-cleaning station. The moving arm 51 can be driven to drive the flipping unit 52 and the adsorption unit 53 to move in the horizontal direction or the vertical direction.

[0078] During the operation, after the loading and unloading manipulator 5 receives the loading signal from the electrical testing device, the loading and unloading manipulator 5 corrects the offset angle according to the offset information described above to adjust its own position, and sucks and holds the product to above the carrier table, and the carrier table moves the product to a predetermined position inside the electrical testing device for testing.

[0079] Optionally, the product can be adsorbed onto the carrier table by the first adsorbing member 5311. After the product is sent above the carrier table, the electrical testing device can clamp the product, and the first adsorbing member 5311 can release the product and withdraw from the electrical testing device. Then, the electrical testing device tests the product.

[0080] After the first adsorbing member 5311 withdraws from the electrical testing device, it moves again to a position close to the post-cleaning station 1121, usually stays above the post-cleaning station 1121, and then, again according to the offset information provided by the alignment unit 6, picks up the product located on the post-cleaning station 1121. After the first adsorbing member 5311 adsorbs the product and rises, it is flipped by the flipping unit 52, and the position of the entire adsorbing unit 53 is adjusted according to the offset information.

[0081] With such a setting, when the adsorbing unit 53 enters the electrical testing device, the second adsorbing member 5321 behind the first adsorbing member 5311 faces the product that has been tested on the carrier table of the electrical testing device and is used to transplant the product.

[0082] Then, the second adsorbing member 5321 sucks the tested product, and the flipping unit 52 rotates the adsorbing unit 53 again, so that the positions of the first mounting surface 531 and the second mounting surface 532 are swapped. In this way, the tested product adsorbed on the second adsorbing member 5321 can be moved to the upper side of the adsorbing unit 53 and used for feeding the upper loading station located above.

[0083] Correspondingly, the product to be tested held by the first adsorbing member 5311 is located at the lower part of the adsorbing unit 33 after rotation. Therefore, it can be conveyed to the carrier table for testing.

[0084] With such a cycle, the setting of the flipping unit 52 greatly improves the efficiency of the flexible circuit board testing mechanism for testing products.

[0085] In this embodiment, the first adsorbing member 5311 and the second adsorbing member 5321 can be configured to include a negative pressure adsorption mechanism.

[0086] Specifically, the first adsorbing member 5311 and the second adsorbing member 5321 can be configured as a negative pressure adsorption mechanism including suction cups. The suction cups can adsorb on the surface of the product, so that the product can be more stably adsorbed on the first adsorbing member 5311 or the second adsorbing member 5321.

[0087] The negative pressure adsorption mechanism can also be configured as a negative pressure adsorption mechanism including a negative pressure generating unit and a negative pressure port. The negative pressure port is formed on the first adsorbing member 5311 and the second adsorbing member 5321, and the negative pressure generating unit is communicated with the negative pressure port; in a negative pressure manner, the product can be adsorbed on the negative pressure port, so that the workpiece can be more stably adsorbed on the first adsorbing member 5311 or the second adsorbing member 5321.

[0088] The adsorption mechanism in this embodiment can be selected in any of the above ways according to actual needs. Any solutions that are the same as or similar to the above embodiments are covered by the protection scope of the present invention.

[0089] In summary, the embodiments of the present invention achieve the following technical effects:

[0090] When the product passes through the space defined by the two dust removal rollers 121, the dust removal rollers 121 can remove dust and foreign matters on the product, and the sticky dust roller 122 can rollingly contact with the dust removal rollers 121 to take away the foreign matters on the dust removal rollers 121. During the shutdown of the equipment, the sticky dust roller 122 can be separated from the corresponding dust removal roller 121 to avoid the formation of residual glue on the dust removal roller 121 due to long-term adhesion between the two, resulting in the pollution of the product by the residual glue.
