Description

Technical Field

[0001] This utility model relates to the technical field of backlight module positioning devices, and in particular to a positioning device for backlight module production. Background Technology

[0002] A backlight module is a component that provides a backlight source for an LCD display. It consists of a backlight source, backlight material, and a support frame. For example, Chinese patent application CN202020958424.X discloses a positioning device for backlight module production. Specifically, the operator fixes the substrate to the mounting position on the processing platform through a set of threaded through holes. The operator places the backlight module to be processed on the substrate and rotates the threaded rotating rod using the handle at the end of the threaded rotating rod, so that the four positioning plates fit precisely with the four edges of the backlight module. However, this method has the following technical problems:

[0003] When the backlight module is clamped at both ends by two positioning plates, the backlight module is movable, so the force on both ends is the same. However, since the backlight module is fixed, when the backlight module is clamped by the two positioning plates on the left and right sides, the threaded rotating rod needs to be rotated. In actual use, it is difficult to ensure that the positioning plates apply the same force to the backlight module, which will cause uneven force on both sides of the backlight module and damage it. Utility Model Content

[0004] To address the problem of damage to backlight modules caused by uneven stress as mentioned in the background section, this utility model provides the following technical solution:

[0005] A positioning device for backlight module production includes a first positioning component;

[0006] The lower end of the first positioning component is equipped with a support component for supporting the first positioning component, and the upper end of the support component is equipped with a second positioning component for cooperating with the first positioning component to position the backlight module.

[0007] The support assembly includes a base plate, and a fixing clamp is installed on the upper end of the base plate.

[0008] The first positioning component includes two first clamping plates arranged symmetrically front to back. A baffle for limiting the backlight module is installed at the lower end of the first clamping plates. The first positioning component includes a bidirectional lead screw for controlling the two first clamping plates to move closer to each other.

[0009] Furthermore, the base plate is equipped with first guide rails at its front and rear ends for guiding the first positioning component.

[0010] Furthermore, a second guide rail for limiting the second positioning component is installed in the middle of the base plate. A first sliding groove is opened in the middle of the second guide rail, and multiple slots are opened at the top of the second guide rail.

[0011] Furthermore, a screw nut is installed at the bottom of the first clamping plate to cooperate with the bidirectional screw to control the movement of the first clamping plate.

[0012] Furthermore, the first positioning component includes a sliding plate for limiting the bidirectional lead screw, a slider is installed at the lower end of the sliding plate, a second sliding groove for limiting the first clamping plate is opened in the middle of the sliding plate, and a turntable for controlling the rotation of the bidirectional lead screw is installed at one end of the bidirectional lead screw.

[0013] Furthermore, the second positioning component includes a second clamping plate for clamping the backlight module in conjunction with the fixing clamping plate, and a locking component is installed on the right side of the second clamping plate.

[0014] Furthermore, a slider 2 that slides within the cavity of the first slide groove is installed at the bottom of the second clamping plate, and a fixing plate for limiting the locking assembly is installed on the right side wall of the second clamping plate.

[0015] Furthermore, the locking assembly includes a pressure plate, the bottom of which is fitted with a locking block for positioning the second clamping plate in conjunction with a locking slot, the upper end of which is fitted with a U-shaped rod, the upper end of which is fitted with a handle for easy lifting of the pressure plate, and the lower end of which is fitted with a spring.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When clamping the backlight module, the turntable rotates, and the lead screw nut controls the two first clamping plates to move closer together, placing the backlight module on the upper end of the baffle. The turntable continues to rotate, causing the two first clamping plates to clamp the front and rear ends of the backlight module with equal clamping force. Then, the second clamping plate is pushed to the right, causing it to contact the right side of the backlight module. Simultaneously, the backlight module and the first positioning component move to the left until the left side of the backlight module contacts the fixed clamping plate, stopping the second clamping plate and the fixed clamping plate to clamp the left and right sides of the backlight module. The second clamping plate is then locked by the locking component to fix the backlight module. The movable first positioning component ensures that the clamping force on the left and right ends of the backlight module is equal, thus preventing damage to the backlight module due to uneven force.

[0027] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0028] Please see Figures 1-5 This utility model provides a positioning device for backlight module production, including a first positioning component 200.

[0029] The lower end of the first positioning component 200 is equipped with a support component 100 for supporting the first positioning component 200. The support component 100 includes a base plate 110. The front and rear ends of the base plate 110 are fixedly equipped with first guide rails 111 for guiding the first positioning component 200. The first guide rails 111 are located at the upper end of the base plate 110. A fixing clamp 112 is installed at the upper end of the base plate 110. The fixing clamp 112 is a positioning plate and is located at the left end of the base plate 110. The fixing clamp 112 is used to limit the left side of the backlight module.

[0030] A second guide rail 120 for limiting the second positioning component 300 is installed in the middle of the base plate 110. The second guide rail 120 is located between two first guide rails 111. A first sliding groove 121 is opened in the middle of the second guide rail 120, and multiple slots 122 are opened on the top of the second guide rail 120.

[0031] The first positioning component 200 includes two first clamping plates 210 arranged symmetrically front to back. A baffle 211 for limiting the backlight module is fixedly installed at the lower end of the first clamping plate 210. When clamping the backlight module, the backlight module is placed on the upper end of the baffle 211. A screw nut 212 for cooperating with the bidirectional screw 230 to control the movement of the first clamping plate 210 is fixedly installed at the bottom of the first clamping plate 210.

[0032] The first positioning assembly 200 includes a bidirectional lead screw 230 for controlling the two first clamping plates 210 to move closer to each other. The helical grooves at the front and rear ends of the bidirectional lead screw 230 rotate in opposite directions. A turntable 231 for controlling the rotation of the bidirectional lead screw 230 is fixedly installed at one end of the bidirectional lead screw 230. The first positioning assembly 200 includes a sliding plate 220 for limiting the bidirectional lead screw 230. A slider 221 is fixedly installed at the lower end of the sliding plate 220 and slides on the first guide rail 111. A second groove 222 for limiting the first clamping plate 210 is opened in the middle of the sliding plate 220.

[0033] When clamping the backlight module, the turntable 231 is rotated. Under the action of the lead screw nut 212, the two first clamping plates 210 are brought closer to each other. Then, the backlight module is placed on the upper end of the baffle 211. The turntable 231 is rotated again, so that the two first clamping plates 210 clamp the front and rear ends of the backlight module, and the clamping force on the front and rear ends of the backlight module is the same.

[0034] The upper end of the support component 100 is equipped with a second positioning component 300 for positioning the backlight module in conjunction with the first positioning component 200. The second positioning component 300 includes a second clamping plate 310 for clamping the backlight module in conjunction with the fixing clamping plate 112. A locking component 320 is movably installed on the right side of the second clamping plate 310.

[0035] The bottom of the second clamping plate 310 is fixedly installed with a slider 311 that slides in the cavity of the first slide groove 121, and the right side wall of the second clamping plate 310 is fixedly installed with a fixing plate 312 for limiting the locking assembly 320.

[0036] The locking assembly 320 includes two pressure plates 321. Multiple locking blocks 322 are fixedly installed at the bottom of the pressure plates 321 to position the second clamping plate 310 in conjunction with the locking slot 122. A U-shaped rod 323 is fixedly installed at the upper end of the pressure plates 321. A handle 324 is fixedly installed at the upper end of the U-shaped rod 323 to facilitate lifting the pressure plates 321. A spring 325 is sleeved on the lower end of the U-shaped rod 323 to push the pressure plates 321 downward.

[0037] When the second clamping plate 310 is moved, the handle 324 is pulled upward, causing the pressure plate 321 to move the locking block 322 away from the slot of the slot 122. After the second clamping plate 310, together with the fixed clamping plate 112, clamps the left and right ends of the backlight module, the handle 324 is released, the spring 325 pushes the pressure plate 321 downward, and the locking block 322 is inserted into the slot of the slot 122, thus completing the limiting of the backlight module.

[0038] After the first clamping plate 210 clamps the front and rear ends of the backlight module, the second clamping plate 310 is pushed to the right, so that the second clamping plate 310 and the right side of the backlight module come into contact. Simultaneously, the backlight module and the first positioning component 200 are moved to the left until the left side of the backlight module comes into contact with the fixed clamping plate 112 and stops. This causes the second clamping plate 310 and the fixed clamping plate 112 to clamp the left and right sides of the backlight module. Through the movable first positioning component 200, the clamping force on the left and right ends of the backlight module is the same, so the backlight module is not easily damaged due to uneven force.

[0039] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
