Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for glue dispensing technology, in particular to a positioning tool for glue dispensing. Background Art

[0002] A display screen is a screen that uses light-emitting diodes as display units. It forms graphics, images or video content after being arranged in a dot matrix. It is generally composed of multiple modules. Common display screens are indoor and outdoor. Different size, brightness, resolution, color and other parameters can be selected according to different application requirements. The PCB board is the core component of the display screen and is a key component for realizing circuit connection and control. In the production process, it is necessary to perform glue dispensing operations in order to improve the display effect, dust and water resistance, and protect the circuit.

[0003] During the dispensing process, the display screen needs to be fixed to prevent the display screen from shifting during the dispensing process and affecting the dispensing effect. In the prior art, a clamping structure is set at the position where the display screen is placed to fix the display screen. For example, the existing patent 201811017342.9 discloses a display touch screen dispensing device and a dispensing method thereof. In paragraphs 0037 and 0038 of the specification, it is explained that the positioning seat includes a first L-shaped plate installed on the base plate, a positioning cylinder installed on the first L-shaped plate, and a positioning head installed on the driving end of the positioning cylinder. The first L-shaped plate is set for installation and fixing, and the positioning cylinder is set to drive the positioning head to position the screen. The positioning effect is good, the screen is prevented from shifting during the dispensing process, and the dispensing accuracy is improved. The pressing seat includes a second L-shaped plate installed on the base plate, a rotating cylinder installed on the second L-shaped plate, and a pressure plate installed on the rotating cylinder. The pressure plate is installed with a pressure head. Specifically, the second L-shaped plate plays a connecting and installing role. At the same time, the rotating cylinder drives the pressure plate to rotate to press the screen, which can further improve the stability of the screen during the dispensing process and greatly improve the dispensing accuracy.

[0004] like Figure 1 As shown in Figure 5 of the specification of the above-mentioned patent disclosure, when fixing the display screen, under the action of the positioning cylinder and the first L-shaped plate, the positioning head realizes the positioning of the screen, and driven by the rotating cylinder and the second L-shaped plate, the pressing plate and the pressing head press the screen, thereby fixing the screen. The fixing of the screen is completed by the positioning cylinder and the rotating cylinder, and the operation is cumbersome, and the positioning head and the pressing head need to be controlled to complete the positioning and pressing of the screen. If the components with the positioning function or the pressing function are damaged, the device cannot be used any more, resulting in increased production costs. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a positioning tool for dispensing glue, aiming to solve the problem in the prior art that when dispensing glue on a display screen, the positioning and pressing of the display screen are achieved by setting a positioning component and a pressing component, resulting in cumbersome operation and high production cost.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is: a positioning tool for dispensing glue, including a base plate, a placement cavity for placing a screen fixed in a screen frame, a cover frame hinged on one side of the placement cavity, the cover frame is hollowed out in the middle, the outer frame length of the cover frame is greater than the length of the placement cavity, the inner frame length of the cover frame is less than the length of the placement cavity and greater than the length of the screen, the outer frame width of the cover frame is greater than the width of the placement cavity, and the inner frame width of the cover frame is less than the width of the placement cavity and greater than the width of the screen.

[0007] The principles of this solution are:

[0008] A placement cavity is opened on the bottom plate, and the screen fixedly installed in the screen frame is placed in the placement cavity. The cover frame hinged on one side of the placement cavity is flipped over and pressed against the edge of the placement cavity, and the outer frame edge of the cover frame is pressed against the bottom plate outside the placement cavity, and the inner frame edge of the cover frame is pressed against the screen frame in the placement cavity, thereby achieving fixation of the screen and the screen frame.

[0009] The beneficial effects of this program are:

[0010] 1. By opening a placement frame on the bottom plate, the screen and the frame are placed in the placement cavity to complete the positioning of the screen, and the cover frame is pressed on the screen frame by flipping it, so as to achieve the positioning and pressing of the screen frame, which has the effects of simple structure, convenient operation and low cost;

[0011] 2. The length and width of the outer frame of the cover frame are respectively greater than the length and width of the placement cavity, and the length and width of the inner frame of the cover frame are respectively greater than the length and width of the placement cavity, ensuring that the cover frame can be pressed tightly on the screen frame when pressing the screen and the screen frame;

[0012] 3. When the cover frame is flipped over to press the screen and the screen frame in the cavity, the outer edge of the cover frame contacts the bottom plate, thereby limiting the cover frame and preventing the cover frame from excessively pressing the screen frame, causing the screen frame and the screen to be offset, misaligned or detached.

[0013] Furthermore, the bottom plate is made of magnetic material and the cover frame is made of magnet. Due to the attraction between the magnet and the magnetic material, when the cover frame is pressed against the placement cavity, the cover frame and the bottom plate are attracted to each other to fix the cover frame, thereby enhancing the pressing effect of the cover frame on the screen and the screen frame in the placement cavity.

[0014] Furthermore, the cover frame is an electromagnet, the cover frame is electrically connected to a power source, and a control switch is provided between the power source and the cover frame. When the tooling is required to realize the pressing of the screen and the screen frame, when the cover frame is pressed against the placement cavity, the control switch is used to control the on and off of the cover frame, thereby controlling the fixing of the cover frame and the placement cavity, and realizing the pressing of the screen and the screen frame.

[0015] Furthermore, L-shaped openings facing outward are provided on the two adjacent sides of the hinged side of the cover frame and the overlapping bottom plate. The L-shaped openings facilitate separation of the cover frame covering the bottom plate where the cavity is located from the bottom plate.

[0016] Furthermore, a transmission track is provided below the bottom plate, a motor is fixedly installed on one side of the transmission track, a screw is fixedly installed on the output shaft of the motor, the other end of the screw is rotatably installed in the transmission track on the opposite side of the motor, a sliding rod parallel to the screw is also fixedly installed in the transmission track, a first slider is threadedly connected to the screw, a second slider is slidably connected to the sliding rod, a support rod is fixedly installed on the first slider and the second slider, and the other end of the support rod is fixedly installed on the bottom end of the bottom plate. The rotation of the motor drives the screw to rotate, and under the limit of the sliding rod and the bottom plate, the rotation of the motor drives the first slider and the second slider to move on the screw and the sliding rod, thereby controlling the bottom plate to move on the transmission track, and then realizing the dispensing of glue at different positions of the screen and the screen frame in the placement cavity.

[0017] Furthermore, a limit frame of the cover frame is provided at the edge of the placement cavity. By setting the limit frame, the position of the cover frame on the positioning plate can be limited, thereby quickly completing the pressing of the screen and the screen frame in the placement cavity.
