Abstract
Description
Technical Field
[0001] This utility model relates to the field of product assembly, specifically to equipment for hot-melting metal internal thread parts onto plastic products. Background Technology
[0002] This is a plastic frame-like part with a smooth, unlined connection hole. A threaded metal component, shaped like a finger ring, is fitted into the connection hole using a press-fit method. To ensure the threaded component remains stable in the connection hole, it is heated. The plastic surrounding the threaded component melts and then cools, thus stabilizing the threaded component in the connection hole. Utility Model Content
[0003] The technical problem solved by this utility model is: how to improve the heat-melting efficiency of the connecting holes on the two sides of frame-type parts.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hot-melt mechanism for product connection holes, including a hot-melt assembly connected to a lifting device and a product positioning module located below the hot-melt assembly. The product positioning module includes a product positioning base plate mounted on a base plate, an inner product positioning block fixed on the product positioning base plate, and a presser that presses the product onto the product positioning base plate. There are two product positioning modules, which enable different sides of the product to face upwards, and connection holes are provided on different sides. The hot-melt assembly includes several hot-melt heads, which can simultaneously extend into the connection holes on different sides of the two products.
[0005] Assume that both side A and side B of the product (frame-type part) have connection holes, and each connection hole is fitted with an internally threaded component. The first product is positioned on the first product positioning module with side A facing upwards; the second product is positioned on the second product positioning module with side B facing upwards. A lifting device drives the thermoforming assembly to descend, and several thermoforming heads engage with the internally threaded components in the connection holes on sides A and B. Simultaneously, the internally threaded components in the connection holes on the two upward-facing sides of the product are heated, causing the contact area between the connection hole and the outer periphery of the internally threaded component to melt. After cooling, the internally threaded component is fixed in the corresponding connection hole.
[0006] Afterwards, with the hot melt assembly in its raised and reset state, the corresponding clamps release the corresponding products. The worker positions the first product on the second product positioning module, with side B facing upwards; and positions the second product on the first product positioning module, with side A facing upwards. The lifting device drives the hot melt assembly to descend, and several hot melt heads engage with the internally threaded parts in the connection holes on sides A and B. Simultaneously, the internally threaded parts in the connection holes on the upward-facing sides of the two products are heated, melting the contact area between the connection holes and the outer periphery of the internally threaded parts. After cooling, the internally threaded parts are fixed in the corresponding connection holes.
[0007] This invention can simultaneously heat-melt the connecting holes on different sides of two products. After completion, the two products exchange positions on two product positioning modules, and the heat-melting component heat-melts the connecting holes on different sides of the two products again. This completes the heat-melting of the connecting holes on two sides of each product, which helps to improve work efficiency, especially the heat-melting efficiency of connecting holes of batch frame parts.
[0008] The press includes a horizontal cylinder housed within the product's internal positioning block and a press head connected to the piston rod of the horizontal cylinder. The press head is hinged to one end of the cylinder body of the horizontal cylinder and is located outside the product's internal positioning block. When the product is fitted onto the product's internal positioning block, the horizontal cylinder actuates, driving the press head to rotate. The press head presses against the edge face of the product, firmly pressing the product onto the product positioning base plate, thus achieving product positioning.
[0009] Each product positioning module has a pair of clamps, which can be arranged horizontally or vertically. Only when the clamps are arranged horizontally or vertically can the product be pressed firmly onto the product positioning base plate.
[0010] The lifting device includes a vertical cylinder mounted on a gantry bracket and a lifting plate connected to the vertical cylinder, with the hot melt assembly mounted on the lifting plate.
[0011] Guide sleeves are provided at both ends of the lifting platform, and the guide sleeves cooperate with a pair of columns of the gantry bracket. The pair of columns guide the lifting of the platform.
[0012] The base plate of the hot-melt mechanism is equipped with a pair of limiting posts, the top of which is screwed with a height adjusting bolt. The descending lifting plate can abut against the height adjusting bolt, limiting the descent of the hot-melt head. Adjusting the height adjusting bolt controls the descent of the hot-melt head.
[0013] This invention enables simultaneous heat melting of connection holes on different sides of two products. After the two products are swapped on the positioning modules, the connection holes on different sides of the two products are simultaneously heat-melted again, thus completing the heat melting of connection holes on two sides of each product. This improves the heat melting efficiency of connection holes in batch frame-type parts. Attached Figure Description

[0026] Combination Figure 1 , Figure 2 , Figure 5The hot-melt mechanism for the product connection holes includes a hot-melt assembly 10 connected to a lifting device and a product positioning module 20 located below the hot-melt assembly. The product positioning module includes a product positioning base plate 21 mounted on a base plate 30, an inner product positioning block 22 fixed on the product positioning base plate, and a press 23 that presses the product onto the product positioning base plate. There are two product positioning modules, which allow different sides of the product to face upwards. Each side has a connection hole 91. The hot-melt assembly 10 includes several hot-melt heads 11, which can simultaneously extend into the connection holes on different sides of the two products.
[0027] like Figure 3 , Figure 4 The press 23 includes a horizontal cylinder 231 disposed in the product inner positioning block 22 and a press head 232 connected to the piston rod of the horizontal cylinder. The press head is hinged to one end of the cylinder body of the horizontal cylinder and is located outside the product inner positioning block.
[0028] The pressure fixtures 23 of any product positioning module 20 are in pairs, either arranged horizontally or vertically.
[0029] like Figure 1 The lifting device includes a vertical cylinder 41 mounted on a gantry bracket 31 and a lifting plate 42 connected to the vertical cylinder. The hot melt assembly 10 is mounted on the lifting plate.
[0030] The lifting plate 42 is provided with guide sleeves 43 at both ends, and the guide sleeves cooperate with a pair of columns 311 of the gantry bracket 31.
[0031] A pair of limiting posts 32 are provided on the base plate 30 of the hot melt mechanism. The top of the limiting posts is screwed with a height adjustment bolt 321, and the descending lifting plate 42 can abut against the height adjustment bolt.
[0032] Combination Figure 2 , Figure 5 Both sides A and B of the product are provided with connection holes 91, and each connection hole is fitted with an internally threaded component 92. The first product is positioned on the first product positioning module with side A facing upwards; the second product is positioned on the second product positioning module with side B facing upwards. The lifting device drives the hot melt assembly 10 to descend, and several hot melt heads 11 engage with the internally threaded components 92 in the connection holes on sides A and B. Simultaneously, the internally threaded components in the connection holes on the two upward-facing sides of the product are heated, causing the contact portion between the connection hole and the outer periphery of the internally threaded component to melt. After cooling, the internally threaded component is fixed in the corresponding connection hole.
[0033] Subsequently, with the hot melt assembly 10 in its raised and reset state, the corresponding clamp 23 releases the corresponding product 90. The worker positions the first product on the second product positioning module with side B facing upwards; and positions the second product on the first product positioning module with side A facing upwards. The lifting device drives the hot melt assembly 10 downwards, and several hot melt heads 11 engage with the internal threaded parts in the connection holes on sides A and B. Simultaneously, the internal threaded parts in the connection holes on the upward-facing sides of the two products are heated, causing the contact portion between the connection hole 91 and the outer periphery of the internal threaded part 92 to melt. After cooling, the internal threaded part is fixed in the corresponding connection hole.
[0034] The product 90 is set on the product positioning block 22. The horizontal cylinder 231 is activated, driving the pressure head 232 to rotate. The pressure head presses against the edge end face of the product, pressing the product firmly onto the product positioning base plate 21, thereby achieving product positioning.
[0035] Adjusting the height adjusting bolt 321 can control the descent range of the hot melt head 11.
