Description

Technical Field

[0001] This utility model relates to the technical field of jigs, and in particular to a jig for assisting in loosening the clamps of ACF mounting trays. Background Technology

[0002] A camera module is an electronic device used to capture images and is widely used in smartphones, smart cars, security monitoring and other fields.

[0003] A camera module typically includes a lens, an image sensor, an image processing chip, and integrated circuits.

[0004] ACF mounting is one of the processes in camera module manufacturing.

[0005] Typically, the ACF mounting process requires the use of an ACF mounting tray to position and fix the camera module.

[0006] Specifically, the ACF mounting tray uses a spring to compress the clamps, causing the clamps to grip the camera module. The ACF mounting tray is also equipped with a push rod, which can push the clamps to compress the springs, causing the clamps to release the camera module.

[0007] When the ACF placement tray is operating normally, the ACF placement tray is always in an automatic cycle without manual intervention. The equipment can drive the push rod to move and push the clamp to release the camera module.

[0008] After the equipment is shut down, when we need to perform parameter verification or tray maintenance, we need to use the pusher to manually push open the ACF mounting tray.

[0009] However, due to the spring force, it is often difficult to manually open the clamps. Utility Model Content

[0010] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a fixture for assisting in loosening the clamps of an ACF mounting tray, which can assist in pushing the push rod of the ACF mounting tray and reduce the difficulty of manually opening the clamps.

[0053] This utility model aims to provide an embodiment of a fixture for assisting in the loosening of ACF mounting tray clamps.

[0054] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, a fixture for assisting in the loosening of ACF mounting trays mainly includes a base plate 100, a push plate 130, and an elbow clamp 170.

[0055] The base plate 100 is used to support the pallet 110. The base plate 100 has a number of limiting posts 120. The limiting posts 120 cooperate to limit the outer peripheral side wall of the pallet 110, thereby facilitating the removal of the pallet 110 from the equipment and its placement on the fixture.

[0056] In some specific embodiments, the base plate 100 is also provided with positioning posts, which are used to insert into the positioning holes at the bottom of the tray 110 to position the tray 110, thereby making the position of the tray 110 on the base plate 100 more accurate.

[0057] The push plate 130 is slidably mounted on the base plate 100. A push block 140 is provided on the push plate 130. The push block 140 has an abutment portion 150 protruding from the side wall of the push plate 130. The abutment portion 150 abuts against the push rod 160 of the tray 110 to push the push rod 160. Thus, the abutment portion 150 can apply force to the push rod 160 to drive the push rod 160 to open the clamp, eliminating the need to directly squeeze and push the push rod 160 by hand to open the clamp. In addition, the push plate 130 and the push block 140 can assist in pushing the push rod 160 of the ACF mounting tray 110, reducing the difficulty of manually opening the clamp.

[0058] In some specific embodiments, the push plate 130 may be provided with multiple push blocks 140, so that the push plate 130 can simultaneously assist in pushing multiple push rods 160.

[0059] In some specific embodiments, the push plate 130 is provided with a mounting groove 200 on the side near the tray 110. The mounting groove 200 is used to install the push block 140. The push plate 130 is also provided with a first bolt 210 for fixing the push block 140.

[0060] In this embodiment, a mounting groove 200 is provided on the side of the push plate 130 near the tray 110. The mounting groove 200 is used to install the push block 140. The push plate 130 is also provided with a first bolt 210 for fixing the push block 140, thereby facilitating the installation and fixing of the push block 140 on the push plate 130.

[0061] Specifically, the top of the mounting slot 200 can be left open, which facilitates the placement of the pusher block 140 into the mounting slot 200.

[0062] In some specific embodiments, the push block 140 can move within the mounting groove 200 along the sliding direction of the push plate 130. The push block 140 is provided with a waist-shaped hole 220 that runs vertically through it. The length direction of the waist-shaped hole 220 is set along the sliding direction of the push plate 130. The waist-shaped hole 220 accommodates the passage of the first bolt 210. Thus, when the first bolt 210 is loosened, the position of the push block 140 can be adjusted, making it convenient to adjust the length of the abutment portion 150 protruding from the push plate 130. In turn, it is convenient to adjust the opening angle of the push block 140 on the clamp.

[0063] Furthermore, two waist-shaped holes 220 are provided, and the two waist-shaped holes 220 are arranged side by side along the width direction of the waist-shaped holes 220. Two first bolts 210 are provided accordingly, thereby making the push block 140 more secure on the push plate 130.

[0064] Reference Figure 3 and Figure 4In some specific embodiments, a guide assembly 230 is provided on the base plate 100. The guide assembly 230 is used to guide the sliding of the push plate 130. The guide assembly 230 includes:

[0065] The limiting seat 240 is fixed on the base plate 100 and is located on the side of the push plate 130 away from the pallet 110;

[0066] The guide rod 250 is fixed on the limit seat 240 and extends along the sliding direction of the push plate 130;

[0067] The linear bearing 260 is fixed on the push plate 130 and sleeved on the outside of the guide rod 250, cooperating with the guide rod 250 for guidance.

[0068] In this embodiment, a guide assembly 230 is provided on the base plate 100. The guide assembly 230 is used to guide the sliding of the push plate 130. The guide assembly 230 includes a limiting seat 240, a guide rod 250, and a linear bearing 260. The limiting seat 240 is fixed on the base plate 100 and is located on the side of the push plate 130 away from the tray 110. The guide rod 250 is fixed on the limiting seat 240 and extends along the sliding direction of the push plate 130. The linear bearing 260 is fixed on the push plate 130 and is sleeved on the guide rod 250. The linear bearing 260 cooperates with the guide rod 250 to guide the sliding of the push block 140, thereby making the sliding of the push block 140 more stable.

[0069] In some specific embodiments, the push plate 130 is provided with a mounting hole 270, which accommodates the linear bearing 260. The push plate 130 is provided with a stop plate 280, and the outer periphery of the linear bearing 260 is provided with a stop groove 290. The stop plate 280 and the stop groove 290 are engaged to restrict the linear bearing 260 from moving out of the mounting hole 270.

[0070] It is understandable that the linear bearing 260 can slide within the mounting hole 270, making it convenient to install the linear bearing 260 into the mounting hole 270. Then, by setting a stop plate 280 on the push plate 130 and cooperating with the stop groove 290 of the linear bearing 260, the movement of the linear bearing 260 within the mounting hole 270 is restricted, thereby facilitating the installation of the linear bearing 260.

[0071] Furthermore, a third bolt can be provided between the stop plate 280 and the push plate 130, and the stop plate 280 can be detachably fixed to the push plate 130 by the third bolt, thereby facilitating the installation and removal of the stop plate 280.

[0072] In some specific embodiments, two guide components 230 may be provided, with the two guide components 230 located on both sides of the connecting rod 180, thereby making the movement of the push plate 130 more stable.

[0073] In some specific embodiments, the base plate 100 is provided with a step 330, which abuts against the side of the push plate 130 near the tray 110 to limit the maximum sliding position of the push plate 130, thereby preventing the push plate 130 from sliding too much and damaging the tray 110.

[0074] Reference Figure 3 and Figure 5 For the elbow clamp 170, the elbow clamp 170 is set on the base plate 100. The elbow clamp 170 includes a connecting rod 180 and a swing arm 190. The connecting rod 180 is connected to the push plate 130. The swing arm 190 swings to drive the connecting rod 180 to push and pull the push plate 130 to move.

[0075] It is understandable that by swinging the swing arm 190 to push and pull the push plate 130 to move, the push plate 130 pushes the push rod 160 to open the clamp, which is beneficial for manual operation. At the same time, it also makes the manual operation of opening the clamp less strenuous, thereby reducing the difficulty of manually opening the clamp.

[0076] In some specific embodiments, the elbow clamp 170 also includes a mounting bracket 300, which is fixed on the base plate 100. The mounting bracket 300 is provided with a guide hole 310 for accommodating the sliding of the connecting rod 180. One end of the swing arm 190 is hinged to the mounting bracket 300, thereby enabling the mounting bracket 300 to guide the sliding of the connecting rod 180. At the same time, the mounting bracket 300 can provide support for the swing of the swing arm 190, making the movement of the connecting rod 180 and the swing arm 190 more stable.

[0077] In some specific embodiments, a transmission arm 320 is also provided between the connecting rod 180 and the swing arm 190. One end of the transmission arm 320 is hinged to one end of the connecting rod 180, and the other end of the transmission arm 320 is hinged to the swing arm 190. This allows the torque generated by the swing of the swing arm 190 to be transmitted to the connecting rod 180 through the transmission arm 320, thereby facilitating the transmission between the swing arm 190 and the connecting rod 180.
