Description

Technical Field

[0001] The utility model relates to the field of pcba ict automatic testing devices, in particular to a pcba ict automatic testing device. Background Art

[0002] PCBA ICT automatic test equipment is an automated test device for printed circuit board assemblies (PCBAs). This equipment usually integrates advanced testing technologies and systems, and can quickly, accurately and comprehensively test the electronic components, circuit connections and electrical performance on PCBAs. The main purpose of PCBA ICT testing is to ensure the quality of circuit boards. By testing the components, connections and functions on the circuit boards, potential defects and problems can be discovered and repaired in a timely manner to ensure that the products meet quality standards and customer needs.

[0003] Existing PCBA ICT automatic test devices often use two clamps to fix the left and right sides of the PCBA board when testing the PCBA board. However, this method cannot effectively restrain the movement and shaking of the PCBA board in the front-to-back direction, which may cause the PCBA board to have position deviation in the front-to-back direction, thereby affecting the test accuracy of the PCBA board. In addition, after the PCBA board is tested, it is usually necessary to manually pick up the PCBA board placed on the test table. If the PCBA board fits tightly to the table, it is easy to cause the manual removal to take a relatively long time, which may affect the efficiency of the overall testing process. In view of this, we propose a PCBA ICT automatic test device. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 5 As shown, this embodiment provides a PCB automatic testing device, including a body 1, a top plate 2 is fixedly installed on the top of the body 1, and a storage plate 3 is fixedly installed on the upper surface of the body 1. The test piece is placed on the top of the storage plate 3, and a horizontal clamping mechanism 4 is provided in the internal cavity of the body 1 for horizontally clamping the test piece placed on the storage plate 3. An auxiliary clamping mechanism 5 is provided in the internal cavity of the body 1 for clamping the other two sides of the test piece, so as to realize simultaneous positioning and fixing of the PCBA board in four directions, thereby more accurately limiting the position of the test piece and reducing position deviation. An ejection mechanism 6 is provided in the storage plate 3 for sliding. After the test piece is tested, the ejection mechanism 6 ejects the test piece from the top of the storage plate 3, making it easier for the operator to take the PCBA board.

[0023] The improvement of this embodiment is that:

[0024] Existing PCBA ICT automatic test equipment often uses two clamps to fix the left and right sides of the PCBA board when testing the PCBA board. However, this method cannot effectively restrain the movement and shaking of the PCBA board in the front-to-back direction, which may cause the PCBA board to have position deviation in the front-to-back direction, thereby affecting the test accuracy of the PCBA board. In addition, after the PCBA board is tested, it is usually necessary to manually pick up the PCBA board placed on the test table. If the PCBA board fits tightly to the table, it is easy for the manual removal to take a relatively long time, which may affect the efficiency of the overall testing process. Therefore, the horizontal clamping mechanism 4 and the auxiliary clamping mechanism 5 are provided to simultaneously clamp and fix the left and right sides and the front and back sides of the PCBA board placed above the storage plate 3, thereby more accurately limiting the position of the test piece, reducing position deviation, and ensuring the accuracy of measurement or processing. In addition, an ejection mechanism 6 is provided. After the inspection of the PCBA board is completed, the horizontal clamping mechanism 4 is started to move. When the PCBA board is not clamped, the horizontal clamping mechanism 4 moves to drive the ejection mechanism 6 to move, pushing the PCBA board placed above the storage plate 3 upward, making it easier for the operator to take the PCBA board, thereby improving the use effect of the device.

[0025] Considering the need to position and fix both sides of the PCBA board during inspection, the structure of the horizontal clamping mechanism 4 is further disclosed. Figure 3 and Figure 4As shown, the transverse clamping mechanism 4 includes two rotating rods 41 rotatably connected to the top of the cavity of the body 1, and the two rotating rods 41 are symmetrically arranged on the left and right sides of the cavity relative to the storage plate 3. A No. 1 belt 42 is commonly sleeved on the two rotating rods 41. When the rotating rod 41 rotates, it drives the No. 1 belt 42 to rotate. Two fixed blocks 43 are fixedly connected to the No. 1 belt 42, and the two fixed blocks 43 are staggered and symmetrically arranged, so that when the No. 1 belt 42 is transmitted, it drives the two fixed blocks 43 to move face to face. A plurality of through slots are opened on the top of the body 1, and connecting plates 44 are fixedly connected to the tops of the two fixed blocks 43, and the connecting plates 44 are respectively arranged through adjacent through slots. When the fixed blocks 43 move, they drive the connecting plates 44 to move, thereby clamping the left and right sides of the PCBA board placed on the storage plate 3.

[0026] Considering that after clamping the left and right sides of the PCBA board, it is also necessary to position and clamp the front and back sides of the PCBA board, the structure of the auxiliary clamping mechanism 5 is further disclosed, such as Figure 3 and Figure 4 As shown, the auxiliary clamping mechanism 5 includes two driving rods 51 rotatably connected to the top of the cavity of the machine body 1, and the two driving rods 51 are symmetrically arranged on the front and rear sides of the cavity. The outer walls of the two driving rods 51 are jointly sleeved with a No. 2 belt 52. The driving rod 51 rotates to drive the No. 2 belt 52 for transmission, and the No. 2 belt 52 is located below the rotating rod 41. Two mounting blocks 53 are fixedly connected to the No. 2 belt 52. The two mounting blocks 53 are staggered and symmetrically arranged so that the No. 2 belt 52 drives the two mounting blocks 53 to move face to face. Positioning plates 54 are fixedly connected to the tops of the two mounting blocks 53, and the two positioning plates 54 are respectively passed through adjacent through slots. The two mounting blocks 53 move face to face, driving the positioning plates 54 to move, clamping the front and rear sides of the PCBA board placed above the storage plate 3, thereby realizing the simultaneous positioning and fixing of the workpiece to be tested in four directions, thereby more accurately limiting the position of the workpiece to be tested, reducing position deviation, and ensuring the accuracy of measurement or processing.

[0027] In order to drive the transverse clamping mechanism 4 and the auxiliary clamping mechanism 5 to operate, Figure 3 As shown, a driving motor 7 is fixedly connected to the bottom of one of the rotating rods 41, and a driving belt 71 is provided on the output end of the driving motor 7, and the side of the driving belt 71 away from the driving motor 7 is provided on one of the driving rods 51. When the driving motor 7 is started, the rotating rod 41 in the horizontal clamping mechanism 4 is driven to rotate. The rotating rod 41 rotates and cooperates with the driving belt 71 to drive the driving rod 51 in the auxiliary clamping mechanism 5 to rotate.

[0028] In order to facilitate the operator to take the PCBA board after the PCBA board is tested, the structure of the ejection mechanism 6 is further disclosed. Figure 4 and Figure 5As shown, the ejection mechanism 6 includes a movable plate 61 slidably connected to the interior of the storage plate 3, a circular groove is provided inside the storage plate 3, and the circular groove is set through the top of the body 1, a connecting rod 62 is fixedly connected to the bottom of the movable plate 61, and the bottom of the connecting rod 62 is set through the circular groove, the inner wall of the circular groove is fixedly connected to a No. 1 return spring 63, and the other side of the No. 1 return spring 63 is fixedly connected to the outer wall of the connecting rod 62, one side of one fixed block 43 is fixedly connected to an extrusion rod 64, and the extrusion rod 64 is located directly below the connecting rod 62, a sliding groove is provided at the top of the cavity of the body 1, a slider 65 is slidably connected in the sliding groove, and the side of the slider 65 away from the sliding groove is fixedly connected to one side of the extrusion rod 64, a slider 65 is provided, and when the extrusion rod 64 moves, the slider 65 can provide stability and guidance to the extrusion rod 64;

[0029] When the multiple clamping plates 8 are driven to not fix the PCBA board, the drive motor 7 is started in the reverse direction, driving the rotating rod 41, the No. 1 belt 42 and the fixed block 43 to move in the reverse direction. The fixed block 43 moves in the reverse direction, pulling the extrusion rod 64 to the left, thereby squeezing the connecting rod 62 upward. At this time, the No. 1 return spring 63 is compressed and deformed, and the connecting rod 62 moves, driving the movable plate 61 to move upward, thereby driving the test piece placed on the storage plate 3 to move upward, making it easier for the operator to pick up the test piece, thereby improving the use effect of the device;

[0030] When multiple clamping plates 8 are driven to clamp and fix the PCBA board, the drive motor 7 is started in the forward direction, driving the rotating rod 41, the No. 1 belt 42 and the fixed block 43 to move forward. The fixed block 43 moves forward, pulling the extrusion rod 64 to move to the right. During the movement of the extrusion rod 64, the connecting rod 62 is no longer squeezed. At this time, under the force of the No. 1 return spring 63 to restore the deformation, the connecting rod 62 is driven to move downward, thereby driving the movable plate 61 to move downward, so that the PCBA board is in contact with the upper surface of the storage plate 3, which is convenient for subsequent inspection work.

[0031] Considering that the connecting plate 44 in the horizontal clamping mechanism 4 and the positioning plate 54 in the auxiliary clamping mechanism 5 can move synchronously to clamp the PCBA board, as shown in FIG. Figure 3 As shown, four clamping plates 8 are slidably connected to the upper part of the body 1. The side of the clamping plate 8 away from the storage plate 3 is fixedly connected to a No. 2 return spring 81. The other sides of the four No. 2 return springs 81 are respectively fixedly connected to one side of the adjacent connecting plate 44 and the positioning plate 54. When the connecting plate 44 moves, the No. 2 return spring 81 and the clamping plate 8 installed on the connecting plate 44 are driven to move, thereby clamping and fixing the left and right sides of the belt side piece placed above the storage plate 3. When the positioning plate 54 moves, the No. 2 return spring 81 and the clamping plate 8 installed on the positioning plate 54 move to clamp and fix the front and rear sides of the belt side piece.

[0032] The second reset spring 81 is provided so that when the clamping plates 8 fixed on the left and right sides of the PCBA board have fixed the left and right sides of the PCBA board, but the clamping plates 8 fixed on the front and rear sides of the PCBA board have not yet contacted the PCBA board, the device is continued to be started to drive the multiple clamping plates 8 to move, so that the clamping plates 8 fixed on the front and rear sides of the PCBA board continue to move to fix the front and rear sides of the PCBA board. When the clamping plates 8 fixed on the front and rear sides of the PCBA board fix the front and rear sides of the PCBA board, the clamping plates 8 fixed on the left and right sides of the PCBA board have already fixed the left and right sides of the PCBA board. Therefore, when the clamping plates 8 fixed on the front and rear sides of the PCBA board move, the clamping plates 8 fixed on the left and right sides of the PCBA board continue to move, squeezing the second reset spring 81 to provide an interval for the clamping plates 8 fixed on the left and right sides of the PCBA board to move, thereby avoiding that when the clamping plates 8 fixed on the front and rear sides of the PCBA board move, the clamping plates 8 fixed on the left and right sides of the PCBA board have no moving space, resulting in motion interference and the like.

[0033] Considering the need to test the PCBA board, such as Figure 1 As shown, a hydraulic rod 9 is fixedly installed on the top of the top plate 2, and a test board 10 is fixedly installed on the driving end of the hydraulic rod 9. When the hydraulic rod 9 is started, the test board 10 is driven to move to perform inspection on the PCBA board placed on the storage plate 3.

[0034] When the present invention is used, the PCBA ict automatic testing device is first placed on top of the storage plate 3. Then, the drive motor 7 is started to drive the rotating rod 41 to rotate, thereby driving the No. 1 belt 42 to rotate, and then driving the two fixed blocks 43 to move. Since the two fixed blocks 43 are arranged in a staggered and symmetrical manner, when the No. 1 belt 42 is driven, it drives the two fixed blocks 43 to move face to face. The movement of the fixed blocks 43 drives the connecting plate 44 to move, thereby driving the No. 2 return spring 81 installed on the connecting plate 44 to move, and then drives the clamping plate 8 to move, clamping and fixing the left and right sides of the PCBA board placed on the storage plate 3.

[0035] When the rotating rod 41 rotates, the driving belt 71 drives one of the driving rods 51 to rotate. The driving rod 51 rotates, driving the second belt 52 to transmit, thereby driving the two mounting blocks 53 to move face to face, and then driving the positioning plate 54 to move. The positioning plate 54 moves, and the second return spring 81 and the clamping plate 8 installed on the positioning plate 54 move to clamp and fix the front and back sides of the PCBA board, so that the PCBA board can be positioned and fixed in four directions at the same time, thereby more accurately limiting the position of the test piece, reducing position deviation, and ensuring the accuracy of measurement or processing;

[0036] When the multiple clamping plates 8 are driven not to fix the PCBA board, the drive motor 7 is started in the reverse direction, driving the rotating rod 41, the No. 1 belt 42 and the fixed block 43 to move in the reverse direction. The fixed block 43 moves in the reverse direction, pulling the extrusion rod 64 to move to the left, thereby squeezing the connecting rod 62 upward. At this time, the No. 1 return spring 63 is compressed and deformed, and the connecting rod 62 moves, driving the movable plate 61 to move upward, thereby driving the PCBA board placed above the storage plate 3 to move upward, making it easier for the operator to pick up the test piece, thereby improving the use effect of the device.
