Description

Technical Field

[0001] The invention relates to the technical field of electrical appliance production, in particular to a foam pasting jig for a television front shell. Background Art

[0002] During the TV production process, the application of foam to the front casing is a crucial step. Foam bonding on the front casing provides cushioning, shock absorption, sealing, and sound insulation, playing a crucial role in improving the overall quality and user experience of the TV. With the continuous development of the TV industry, the market is placing higher demands on the appearance, quality, performance, and production efficiency of TVs.

[0003] The traditional pasting method has the following disadvantages:

[0004] 1. Low manual pasting precision: Traditionally, foam pasting for TV front covers is done manually, with operators relying on experience and visual inspection to cut and paste the foam. This method makes it difficult to ensure precise placement of the foam, and can easily lead to problems such as skewed or offset pasting, affecting the appearance quality and sealing performance of the TV.

[0005] 2. Low production efficiency: Manual foam bonding is relatively slow, especially in large-scale production, and it is difficult to meet the requirements of efficient production line operation. Moreover, manual operation is easily affected by factors such as operator fatigue and mood, resulting in unstable bonding quality, increased defective product rate, and thus affecting production efficiency and cost control.

[0006] 3. High labor intensity: Manual foam pasting requires operators to repeatedly cut and paste for a long time. The high labor intensity can easily lead to operator fatigue, further affecting the pasting quality and work efficiency. Long-term engagement in this repetitive labor may also cause certain damage to the operator's physical health.

[0007] To address the aforementioned issues associated with traditional manual foam application, improve the quality and efficiency of TV front cover foam application, and reduce labor intensity, the development of a specialized TV front cover foam application jig is essential. This jig, through precise positioning and guiding mechanisms, ensures that the foam is accurately applied to the designated location on the TV front cover, improving application accuracy and quality. Furthermore, the jig enables mechanized or semi-mechanized foam application, improving production efficiency, reducing labor intensity, and meeting the needs of large-scale TV production. Summary of the Invention

[0008] In order to solve the technical problems existing in the background technology, the present invention provides a foam pasting jig for the front shell of a television.

[0009] The present invention provides a foam sticking jig for a front shell of a television, comprising a base, a limiting block, a pressing block and a slider. The base is provided with a slide rail, and the slider can move on the slide rail.

[0010] The limit blocks and the pressure blocks are installed on the base. The limit blocks are provided in three groups, which are respectively located at the front, middle and rear parts below the slide rails, and are used to limit the front shell. The pressure blocks are provided in two groups, and the two groups of pressure blocks are located below the three groups of limit blocks, and are used to position the front shell.

[0011] The sliding block gradually compresses the foam during the sliding process on the sliding rail.

[0012] Preferably, a guide rail guide is provided on the slider, and the slider is engaged with the slide rail via the guide rail guide.

[0013] Preferably, the limit blocks located at the front are used to limit the movement of the front shell in the -X and Y directions, and the two groups of limit blocks located in the middle and rear are used to limit the warping deformation of the front shell.

[0014] Preferably, the positions of the two groups of pressing blocks can be adjusted in the Y-axis direction of the base, and the pressing blocks can limit the movement of the front shell in the -Y direction.

[0015] Preferably, a groove is provided on the base, and a key is provided on the pressure block, and the pressure block can be clamped in the groove through the key, and a spring is provided between the key and a side of the groove away from the slide rail.

[0016] Preferably, a waist-shaped groove is provided on the base in the Y-axis direction, and the pressing block is movably connected to the waist-shaped groove by bolts, and the position of the pressing block on the waist-shaped groove is adjusted by the bolts.

[0027] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention, and are not to be construed as limiting the present invention.

[0028] like Figure 1-Figure 5 The foam sticking jig for the front shell of a television shown in the figure comprises a base 1, a limit block 3, a pressing block 4 and a slider 5. The base 1 is provided with a slide rail 2, and the slider 5 can move on the slide rail 2;

[0029] The limit blocks 3 and the pressure blocks 4 are installed on the base 1. The limit blocks 3 are provided in three groups, which are respectively located at the front, middle and rear parts below the slide rail 2 to limit the front shell; the pressure blocks 4 are provided in two groups, and the two groups of pressure blocks 4 are located below the three groups of limit blocks 3 to position the front shell;

[0030] The slider 5 gradually compresses the foam during the sliding process on the slide rail 2 .

[0031] Preferably, a guide rail guide 503 is provided on the slider 5 , and the slider 5 is engaged with the slide rail 2 via the guide rail guide 503 .

[0032] Preferably, the limit block 3 located at the front is used to limit the movement of the front shell in the -X and Y directions, and the two groups of limit blocks 3 located in the middle and rear are used to limit the warping deformation of the front shell.

[0033] Preferably, the positions of the two groups of pressing blocks 4 can be adjusted in the Y-axis direction of the base 1 , and the pressing blocks 4 can limit the movement of the front shell in the -Y direction.

[0034] Preferably, a groove is provided on the base 1 , and a key is provided on the pressure block 4 , and the pressure block 4 can be engaged in the groove through the key, and a spring is provided between the key and the side of the groove away from the slide rail 2 .

[0035] Preferably, the base 1 is provided with a waist-shaped groove in the Y-axis direction, and the pressure block 4 is movably connected to the waist-shaped groove by bolts. The position of the pressure block 4 on the waist-shaped groove can be adjusted by adjusting the bolts. By adjusting the tightness of the bolts, the position of the pressure block 4 on the waist-shaped groove can be changed to adapt to different sizes of TV front cabinets. The limit block 3 and the pressure block 4 can fix the front cabinet and prevent it from moving, and can adapt to different sizes of front cabinets.

[0036] Preferably, a pressing groove 502 is provided on the slider 5 for gradually pressing the foam when the slider 5 slides on the slide rail 2 . The contact surface between the pressing groove 502 and the foam is a transition curved surface that gradually presses the foam.

[0037] Preferably, a handle 501 is installed on the slider 5 to facilitate moving the slider 5.

[0038] Place the front shell against the limit block 3, fix the pressure block 4 on the left (only the first front shell needs to match the size), and press the front shell on the right with the spring pressure block 4 (at this time, the limit block 3 and the pressure block 4 cooperate with each other to limit the rotation of the front shell in the three axes of -X, ±Y, -Z, and XYZ. When the slider 5 is pressed down and moved to the left, the movement in the X and Z directions is limited, ensuring the complete constraint of the front shell). First, manually stick a small section of foam, and then starting from this small section, use the slider 5 to press the foam and move it from right to left along the guide rail. The foam quickly sticks to the front shell under the guidance of the pressure groove 502. Pull open the spring pressure block 4, take out the pasted front shell, replace the new front shell and release the spring pressure block 4, and repeat the above steps.

[0039] The television front cover foam pasting jig of the present invention eliminates the need to align and paste the foam piece by piece. Instead, the jig only needs to align the beginning, and then the jig slider 5 can be pulled all the way to the bottom to paste the entire foam piece, thereby greatly improving production efficiency. At the same time, the standardization and consistency of production operations are enhanced, thereby improving production quality.
