Description

Technical Field

[0001] This utility model relates to the field of patch testing fixture technology, specifically a patch testing fixture. Background Technology

[0002] Surface mount devices (SMDs) are a type of electronic component primarily used to connect conductive circuits on circuit boards, enabling signal transmission and circuit operation. Compared to traditional through-hole components, SMDs offer advantages such as smaller footprint, lighter weight, and more stable performance, making them widely used in electronic products and equipment. Before use, SMDs are typically inspected using a surface mount testing fixture to help control their position and ensure quality and reliability, thereby guaranteeing the stability and safety of electronic products.

[0003] However, some surface mount testing fixtures, due to the precision of the surface mount components, cannot withstand impacts. Therefore, most of these fixtures only serve to fix the surface mount components in place, making it inconvenient to remove them after testing. Consequently, they do not meet the current requirements. To address this, we propose a surface mount testing fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a patch inspection fixture to solve the problem mentioned in the background art that, when using some patch inspection fixtures, because the patches are relatively delicate and cannot be impacted, the inspection fixtures mostly only serve to fix the patches, but are inconvenient to remove after the inspection is completed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a patch testing fixture, including a fixture platform, a placement groove is provided in the middle of the upper end of the fixture platform, sliding grooves are provided on the front and back of the inner wall of the placement groove, a fixing plate is slidably connected between the front and back sliding grooves and on both sides inside the placement groove, a groove is provided at the bottom of the fixing plate inside the placement groove, a support plate is provided inside the groove, and the support plate movably passes through the groove and extends into the interior of the placement groove, a driving groove is provided at the bottom of the groove and inside the fixture platform, and a connecting rod for driving the support plate is provided inside the driving groove.

[0006] Preferably, the two fixing plates are rotatably connected to threaded rods on the sides away from each other via a rotating shaft. The threaded rods are threaded through the fixture table at the end away from the fixing plates and extend to the outside of the fixture table. Rubber pads are fixedly connected to the sides of the two fixing plates that are close to each other.

[0007] Preferably, a limiting plate is fixedly connected to the outer surface of one end of the connecting rod inside the drive groove, and a first spring is fixedly connected between the upper end of the limiting plate and the top end of the inner wall of the drive groove, and the first spring is wound around the outer surface of the connecting rod.

[0008] Preferably, the bottom of the fixture platform has a strip groove that is connected to the drive groove in the middle. The upper end of the connecting rod is fixedly connected to the bottom end of the support plate. The bottom end of the connecting rod extends through into the strip groove and is fixedly connected to a protrusion. The protrusion is arc-shaped.

[0009] Preferably, a movable rod is slidably connected inside the strip groove, and a second spring is fixedly connected between one end of the movable rod and the inner wall of the strip groove. A push rod that passes through the strip groove and extends to the outside of the fixture table is fixedly connected to the end of the movable rod away from the second spring.

[0010] Preferably, the upper end of the movable rod near the second spring has an arc groove, the protrusion is movably engaged inside the arc groove, the outer surface of the upper end of the arc groove is arc-shaped, and the outer surface of the protrusion slides in contact.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model places the patch inside the placement groove, and then rotates the threaded rods on both sides of the fixture table, so that the threaded rods on both sides rotate through the rotating shaft to one side of the fixing plate and the threads pass through the fixture table, thereby pushing the fixing plates on both sides to move along the slide groove towards the side closer to each other. The patch is fixed and tested according to its size. The rubber pad connected to one side of the fixing plate contacts the outer surface of the patch, which can prevent the patch from being clamped too tightly and damaged.

[0013] 2. This utility model pushes the push rod, causing the push rod to drive the movable rod to compress the second spring. At this time, the movable rod moves and causes the outer surface of the upper end of the arc groove to slide into contact with the outer surface of the protrusion, causing the protrusion to move out of the arc groove and push the limiting plate on the outer surface of the connecting rod to compress the first spring. This causes the top end of the connecting rod to extend through into the groove and push the tray to move out of the groove. Then, by moving the tray upward, the patch is pushed out of the placement slot, thus facilitating the removal of the patch. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 3 An embodiment of this utility model provides a patch testing fixture, including a fixture platform 1. A placement groove 101 is provided in the middle of the upper end of the fixture platform 1. Sliding grooves 102 are provided on the front and back of the inner wall of the placement groove 101. Fixing plates 2 are slidably connected between the two sliding grooves 102 and on both sides inside the placement groove 101. A groove 103 is provided at the bottom of the two fixing plates 2 inside the placement groove 101. A support plate 5 is provided inside the groove 103 and moves through the groove 103 and extends into the placement groove 101. A driving groove 104 is provided at the bottom of the groove 103 and inside the fixture platform 1, and is connected to the groove 103. A connecting rod 6 for driving the support plate 5 is provided inside the driving groove 104.

[0020] Both fixed plates 2 are rotatably connected to threaded rods 3 on the opposite sides via a pivot. The threaded rod 3, at the end away from the fixed plate 2, passes through the fixture table 1 and extends to the outside of the fixture table 1. Both fixed plates 2 are fixedly connected to rubber pads 4 on the opposite sides.

[0021] By placing the patch inside the placement slot 101, and then rotating the threaded rods 3 on both sides of the fixture table 1, the threaded rods 3 on both sides rotate on one side of the fixing plate 2 via the rotating shaft and thread through the fixture table 1, thereby pushing the fixing plates 2 on both sides to move along the slide 102 toward the side that is closer to each other. The patch is fixed and tested according to its size. The rubber pad 4 connected to one side of the fixing plate 2 contacts the outer surface of the patch, which can prevent the patch from being clamped too tightly and damaged.

[0022] A limiting plate 7 is fixedly connected to the outer surface of one end of the connecting rod 6 inside the drive groove 104. A first spring 8 is fixedly connected between the upper end of the limiting plate 7 and the top of the inner wall of the drive groove 104, and the first spring 8 is wound around the outer surface of the connecting rod 6. A strip groove 105 is opened in the middle of the bottom end of the fixture table 1, which is connected to the drive groove 104. The upper end of the connecting rod 6 is fixedly connected to the bottom end of the support plate 5, and the bottom end of the connecting rod 6 extends through into the inside of the strip groove 105, and is fixedly connected to a protrusion 9. The protrusion 9 is arc-shaped. A movable rod 10 is slidably connected inside the 105. A second spring 11 is fixedly connected between one end of the movable rod 10 and the inner wall of the strip groove 105. A push rod 12 that passes through the strip groove 105 and extends to the outside of the fixture table 1 is fixedly connected to the end of the movable rod 10 away from the second spring 11. An arc groove 1001 is opened at the upper end of the movable rod 10 near the second spring 11. A protrusion 9 is movably engaged inside the arc groove 1001. The outer surface of the upper end of the arc groove 1001 is arc-shaped, and the outer surface of the protrusion 9 slides in contact.

[0023] By pushing the push rod 12, the push rod 12 causes the movable rod 10 to compress the second spring 11. At this time, the movable rod 10 moves to cause the outer surface of the upper end of the arc groove 1001 to slide into contact with the outer surface of the protrusion 9, causing the protrusion 9 to move out of the interior of the arc groove 1001 and push the limiting plate 7 on the outer surface of the connecting rod 6 to compress the first spring 8, so that the top end of the connecting rod 6 extends through into the interior of the groove 103 and pushes the support plate 5 to move out of the groove 103. Then, by moving the support plate 5 upward, the patch is pushed out of the placement groove 101, thus making it easy to remove the patch.

[0024] When using the patch testing fixture, the patch is placed inside the placement slot 101. Then, by rotating the threaded rods 3 on both sides of the fixture table 1, the threaded rods 3 on both sides rotate on one side of the fixing plate 2 through the rotating shaft and threaded through the fixture table 1, thereby pushing the fixing plates 2 on both sides to move along the slide 102 towards each other. The patch is fixed and tested according to its size. The rubber pad 4 connected to one side of the fixing plate 2 contacts the outer surface of the patch, which can prevent the patch from being clamped too tightly and damaged.

[0025] After the patch inspection is completed, the push rod 12 is pushed, causing the movable rod 10 to compress the second spring 11. At this time, the movable rod 10 moves and causes the outer surface of the upper end of the arc groove 1001 to slide into contact with the outer surface of the protrusion 9, causing the protrusion 9 to move out of the arc groove 1001 and push the limiting plate 7 on the outer surface of the connecting rod 6 to compress the first spring 8, so that the top end of the connecting rod 6 extends through into the interior of the groove 103 and pushes the support plate 5 to move out of the groove 103. Then, by moving the support plate 5 upward, the patch is pushed out of the placement slot 101, which makes it easy to remove the patch.
