Description

Technical Field

[0001] The present invention belongs to the field of mechanical technology and relates to a hot melt assembly device, in particular to a heating and pressing device and an operating method thereof. Background Art

[0002] The assembly of the shell components and other parts in electronic products requires a hot melt process to press and bond the two together. The traditional heating method uses a heating rod for heating. The surface of the heating component is made of iron material. If the distance is too close, it will interfere with small parts. If it is far away from the product, there will be no interference, but it will waste heat. The traditional heating method uses the heating rod as the center to form a circumferential divergent heating, which leads to concentrated heat and unbalanced heating. The traditional thermal conductive material is brass, which can easily cause surface damage to slightly softer materials such as pressed aluminum parts. The traditional heating assembly pressing fixture uses copper blocks for heat conduction, and the overall structure is relatively heavy, and the guide is prone to jamming.

[0003] For example, a Chinese patent document once disclosed a hot melt pressing jig [Chinese Patent No.: 201721107338.2]. The utility model discloses a hot melt pressing jig, comprising a base plate, a mounting frame mounted on the base plate, an up and down motion device mounted on the mounting frame, the up and down motion device connected to the mounting plate, and the up and down motion device drives the mounting plate to move up and down; a guide column is mounted on the base plate, and the mounting plate moves up and down along the guide column; a heating copper plate is connected under the mounting plate, and a hot melt head is connected under the heating copper plate; a middle frame positioning module is provided on the base plate under the hot melt head; the utility model has a simple structure and realizes the automatic welding of the middle frame and metal parts of the smart watch. The welded products have high consistency, consistent appearance, and high welding efficiency, which solves the welding error problem, improves the assembly accuracy of the smart watch, and reduces the welding cost.

[0004] The above technical solution can only realize a relatively simple combination of products and parts, so its positioning and fitting structure is relatively simple. When faced with smaller parts and a relatively narrow and cramped assembly position, the positioning and fitting structure cannot accurately fix the small parts in place, and it is easy to cause gaps between the small parts and the product, which in turn leads to assembly failure, defective finished products, and economic losses.

DETAILED DESCRIPTION

[0053] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0054] Example 1

[0055] like Figures 1 to 5 As shown, the heating and pressing device includes a substrate 1 with a loading area, an operation window is opened on the loading area, an auxiliary material positioning mechanism is arranged at the operation window, a main material positioning mechanism is arranged around the loading area, the loading area passes through the top suction component from below, a hot pressing area is formed between the top suction component and the auxiliary material positioning mechanism, a heating and pressing mechanism is arranged on one side of the hot pressing area, the heating and pressing mechanism includes a moving component, a lower pressure heating component and a side pressure heating component are connected to the moving component, the lower pressure heating component is located above the hot pressing area, and the side pressure heating component is located on the side of the hot pressing area.

[0056] Several support blocks 2 are positioned along the edges of the loading area, each with a contoured structure on its top surface. Product 34 is a flat shell with an internal groove containing a characteristic structure. These support blocks 2 coordinate to support the characteristic structure at various locations, maintaining the overall product 34 horizontal. Multiple support points facilitate correcting deformation of the product 34.

[0057] The auxiliary material positioning mechanism includes a push cylinder 3 fixed to the bottom of the base plate 1. The push cylinder 3 pushes up to drive the push rack 4. The push rack 4 extends above the base plate 1 through the operation window. Guide rails are fixed on both sides of the top surface of the operation window. Guide blocks are set on both sides of the push rack 4. The guide blocks are correspondingly connected to the guide rails to form a sliding connection. The upper end of the guide rail is fixed with a push limit post 5. The push rack 4 and the push limit post 5 form a limit block. The quick-change part 32 carrying the small part 33 is placed on the push rack 4. The push cylinder 3 pushes up to drive the quick-change part 32 to the specified position. At the same time, the push rack 4 presses against the push limit post 5 to form a position, thereby preventing the small part 33 from moving upward excessively.

[0058] A pneumatic ejector cylinder 6 is mounted below the pusher frame 4. This cylinder raises and lowers a lift plate, which has positioning pins protruding from its surface. Two pneumatic ejector cylinders 6 are symmetrically positioned, with the lift plate located below the hot pressing area. By pushing the lift plate upward with the cylinders 6, the positioning pins are inserted through the quick-change element 32 to achieve positioning.

[0059] The main material positioning mechanism includes a centering cylinder 7 fixed to the top surface of the base plate 1, and the centering cylinder 7 pushes and pulls the centering frame 8. Clamping components are arranged on both sides of the loading area. The clamping components include a clamping block 9 connected to the base plate 1 in a translational manner. The outer side of the clamping block 9 is elastically pressed by a bolt 10 connected to a spring 11. An oblique groove is recessed on the clamping block 9, and an inclined notch is recessed on the branch rod of the centering frame 8. The branch rod passes through the clamping block 9, so that the oblique notch and the oblique groove are engaged to form a sliding inward push connection.

[0060] Bolts 10 are inserted into the outer edge of base plate 1, with springs 11 compressed between them. The inner ends of bolts 10 press against the outer walls of clamping blocks 9. Product 34 is placed in the loading area, and centering cylinder 7 pushes out centering frame 8. The synchronous branch rods move upward, causing the inclined notch and the oblique slot to slide relative to each other. The inclination angle of the contact surface pushes clamping blocks 9 inward, thereby clamping both sides of product 34.

[0061] The main material positioning mechanism also includes several rotating cylinders 12 fixed around the loading area. Pressing claws 13 are fixed to the rotating axes of the rotating cylinders 12. These press claws 13 swing and extend above the loading area. When a product 34 is placed in the loading area, the rotating cylinders 12 swing and press claws 13 press against the top surface of the product 34, locking it longitudinally.

[0062] The main material positioning mechanism also includes a support base 14 fixed to the bottom of the loading area. A floating block 15 is attached to support base 14 via an elastic column, with floating block 15 facing the loading area. Support base 14 and floating block 15 are symmetrically mounted on either side of centering cylinder 7. Floating block 15 supports the bottom edge of product 34, providing elastic support and preventing product 34 from falling.

[0063] The top suction assembly includes a top suction cylinder 16 fixed to the bottom of the base plate 1. The top suction cylinder 16 drives the top suction rod 17 to rise and fall. The top suction rod 17 passes through the base plate 1 from bottom to top to form a movable connection. There are two top suction cylinders 16, which are arranged symmetrically on the left and right. The top suction rod 17 is located below the hot pressing area. The top suction cylinder 16 pushes the top suction rod 17 to make it contact the bottom fold edge of the product 34. The magnetic force of the small part 33 is used to attract the top suction rod 17, so that the small part 33 is attached to the inner side of the bottom fold edge, eliminating the gap and ensuring precise positioning.

[0064] The moving assembly includes a push cylinder 18 and a slide rail fixed to the base plate 1. The push rod of the push cylinder 18 is fixedly connected to an extension bracket 19. The bottom of the extension bracket 19 is engaged with the slide rail via a sliding frame 20, forming a sliding connection. A push limit pin 21 is fixed to the lower end of the slide rail, and the slide frame 20 and the push limit pin 21 form a limit block. The push cylinder 18 extends or retracts the push rod to drive the extension bracket 19 to reciprocate along the slide rail. When the extension bracket 19 is driven forward to a set position, the slide frame 20 abuts against the push limit pin 21 to form a fixed position, thereby preventing the extension bracket 19 from moving forward too far.

[0065] The downward pressing heating assembly includes a downward pressing cylinder 22 fixedly mounted below the extension bracket 19. The downward pressing cylinder 22 drives the downward pressing heating module to rise and fall. The downward pressing heating module includes a guide plate 24, a downward pressing insulation block 25 and a downward pressing heating pad 26 from top to bottom. A guide column 23 is erected below the extension bracket 19. A corresponding guide hole is opened on the guide plate 24. The guide column 23 passes through the guide hole to form a sliding connection.

[0066] Guide plate 24 is fixed to the lifting end of downward pressure cylinder 22, and is used by downward pressure cylinder 22 to drive the entire downward pressure heating module up and down along guide column 23. The downward pressure heating pad 26 heats the small component 33 to the required temperature for pressing and curing, while also increasing the heating area and improving curing efficiency. The downward pressure insulation block 25 provides thermal insulation between the downward pressure heating pad 26 and other components. The guide plate 24 secures the guide components and floating components. The guide column 23 provides guidance to prevent overpressure caused by the pressing and jamming.

[0067] The side pressure heating assembly includes a lifting cylinder 27 fixed to the bottom of the sliding frame 20. The lifting cylinder 27 drives the side pressure heating module to rise and fall. The side pressure heating film group includes a mounting plate 28, a side pressure insulation block 29 and a side pressure heating pad 30 from the outside to the inside. A limit shaft 31 is arranged parallel to the bottom of the side pressure heating pad 30. A feeding gap is formed between the protruding heating strip of the side pressure heating pad 30 and the limit shaft 31. A vertical rail is fixed on the mounting plate 28, and a vertical block is fixed on the sliding frame 20. The vertical rail is embedded in the vertical block to form a sliding connection. A limit plate is protruded on the sliding frame 20, and the mounting plate 28 is located below the limit plate to form a limit block.

[0068] The mounting plate 28 is fixedly connected to the lifting rod of the lifting cylinder 27, and the lifting cylinder 27 drives the entire side pressure heating module to slide vertically upward and downward. The product 34 is pushed into the feed gap between the heating strip and the limiting shaft 31, and is heated to the temperature required for the pressing and curing of the small part 33 by the side pressure heating pad 30. The side pressure insulation block 29 provides thermal insulation protection between the side pressure heating pad 30 and other parts. When the side pressure heating pad 30 rises to the set position, the mounting plate 28 presses against the limiting plate to form a fixed position, thereby preventing the side pressure heating pad 30 from moving upward excessively.

[0069] The downward pressure heating pad 26 / side pressure heating pad 30 comprises a flexible pad body, through which at least one temperature-sensing wire and several heating wires are inserted. The heating wires are coiled evenly within the flexible pad body. The heating wires heat the product 34, while the temperature-sensing wires sense the actual temperature for easy control. Heat is then transferred from the flexible pad body to the product 34 surface, causing it to heat and melt. The flexible pad body also provides a resilient, cushioning effect, preventing damage to the product 34 surface.

[0070] Compared with the existing technology, this heating and pressing device has the following beneficial effects:

[0071] 1. The X and Y direction pushing structure is combined with the suction positioning structure to ensure the tightness and position accuracy of small parts and products, improve the assembly effect, optimize the quality of finished products, increase the yield rate of finished products, and increase economic benefits.

[0072] 2. Use flexible materials for pressing and heating to provide elastic buffer pressure, protect the surface of the product 34, reduce the risk of product damage, and improve the yield rate of finished products.

[0073] 3. The coil is used to generate heat, forming overall surface heating, which makes the heating speed fast, uniform and without interference, improves the utilization rate of heat and reduces energy waste.

[0074] 4. The overall structure is light in weight, which reduces the load on the power source. The guide position during movement is not easily stuck even in a suspended state, ensuring smooth sliding.

[0090] 13) Power is supplied to the downward pressure heating pad 26 and the side pressure heating pad 30 to heat the product 34 and melt the adhesive to fix the small piece 33 to the inner side of the product 34.

[0091] In the operation method of the heating and pressing device, the unloading and returning steps are as follows:
