Description

Technical Field

[0001] This invention relates to the field of carrier tape forming technology, and in particular to a carrier tape flat plate forming system based on multi-ribbed deep cavity. Background Technology

[0002] Carrier tape is a strip-shaped packaging product used in the electronics and packaging fields. It has a specific thickness and evenly distributed holes (also called pockets) along its length for holding electronic components and positioning holes for indexing and positioning. There are two main types of carrier tape forming machines: roller type and flat type. The difference between the two lies in their forming methods.

[0003] The forming principle of carrier tape on a flatbed press is as follows: the leather material is first heated to a certain temperature by the heating section (i.e., upper and lower preheating molds) of the press. The extension and retraction of a cylinder then moves the leather material forward to the forming die. The forming die, via a cam, moves to the position of the heated and softened leather material, and air is blown into the forming die cavity. The forming die contains a number of pocket cavities, each with several small holes at its bottom for blow molding. These holes ensure that the heated leather material adheres tightly to the inner cavity of the forming die, forming a pocket shape consistent with the lower mold cavity. The material then moves intermittently at intervals of a certain length. After passing through a punching system to punch out side holes and pocket holes, the material is pulled forward by a conveyor system into a slitting system, where it is slit into carrier tape of a certain width. Finally, it passes through a winding system for winding. When the set length is reached, the production of one roll of finished product is complete.

[0004] This forming method works well for carrier tape products with shallow pockets, generally meeting the forming requirements. However, for carrier tapes with deeper pockets or those containing multiple ribs or cavities, this air-blowing method alone cannot meet the forming requirements of the pockets. During the leather forming process, poor forming, deformation, or pocket damage are likely to occur. This fails to meet normal process requirements, hinders mass production, and results in wasted raw materials. Summary of the Invention

[0005] The present invention aims to provide a multi-ribbed deep cavity carrier plate forming system to overcome the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a multi-ribbed deep cavity carrier plate forming system, including a first transport device and a second transport device, wherein a preheating mechanism, an auxiliary forming mechanism and a punching device are provided between the first transport device and the second transport device.

[0007] As an improvement of the multi-ribbed deep cavity carrier plate forming system of the present invention, the preheating mechanism includes a preheating upper cylinder, a preheating lower cylinder, a preheating upper mold and a preheating lower mold, wherein the working end of the preheating upper cylinder is fixedly connected to the preheating upper mold, the working end of the preheating lower cylinder is fixedly connected to the preheating lower mold, and the preheating upper mold cooperates with the preheating lower mold to preheat the leather material.

[0008] As an improvement to the multi-ribbed deep cavity carrier plate forming system of the present invention, the auxiliary forming mechanism includes an auxiliary mold cylinder, an auxiliary mold base, an air blowing cover plate, an auxiliary mold, a forming die, a forming die base, a mold base guide post, a guide post spring, and a support plate. The working end of the auxiliary mold cylinder is fixedly connected to the auxiliary mold base. The air blowing cover plate is installed at the bottom of the auxiliary mold base. The auxiliary mold is installed at the bottom of the air blowing cover plate. The forming die is installed on the forming die base. The forming die base is installed on the mold base guide post with nested guide post spring. The mold base guide post penetrates the bottom of the forming die base and contacts the bottom of the forming die.

[0009] As an improvement of the multi-ribbed deep cavity carrier plate forming system of the present invention, the transport mechanism includes a belt slide rail and a belt clamp. The belt slide rail is used to transport the leather material, and the belt clamp is set on the belt slide rail and consists of upper and lower parts. When the belt clamp is activated, it clamps the leather material in the middle and moves on the belt slide rail.

[0010] As an improvement to the multi-ribbed deep cavity carrier plate forming system of the present invention, the second transport mechanism includes a second belt-pulling slide rail, a second belt-pulling clamp, and a fixing clamp. The second belt-pulling slide rail is composed of upper and lower parts. The fixing clamp performs a releasing and clamping action. The first belt-pulling clamp and the second belt-pulling clamp simultaneously clamp the leather material. The leather material is pushed forward by moving from one end of the first belt-pulling slide rail to the other end of the second belt-pulling slide rail at a fixed distance, thus completing the preheating and forming of the leather material. During the movement, the fixing clamp is in a released state. When the first belt-pulling clamp and the second belt-pulling clamp complete a belt-pulling action, the upper and lower clamps will be in a released state and return to the initial position of the slide rail. At this time, the fixing clamp starts to move, clamping and fixing the leather material. The punching equipment punches holes, completing a complete leather material pushing stroke.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: The main function of the auxiliary molding device during operation is to help the leather material quickly and fully conform to the mold cavity, resulting in a more square and complete pocket formation. This is particularly beneficial for pockets with multi-ribbed or multi-cavity structures, leading to higher strength. It effectively improves the forming effect and strength of carrier products with multiple cavities and deep pockets. During forming, the leather material is subjected to pressure from the auxiliary mold, and the pressure during air blowing is more concentrated, which is beneficial for the leather material to soften after heating and then be blow-molded. The bottom of the pocket experiences uniform force, resulting in good forming effect, and the formed pocket has high strength and is less prone to deformation. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figure 1 As shown, a multi-ribbed deep cavity carrier plate forming system includes a first transport device and a second transport device. The system is characterized in that a preheating mechanism, an auxiliary forming mechanism, and a punching device are provided between the first transport device and the second transport device.

[0017] The preheating mechanism includes an upper preheating cylinder 3, a lower preheating cylinder 6, an upper preheating mold 4, and a lower preheating mold 5. The working end of the upper preheating cylinder 3 is fixedly connected to the upper preheating mold 4, and the working end of the lower preheating cylinder 6 is fixedly connected to the lower preheating mold 5. The upper preheating mold 4 works in conjunction with the lower preheating mold 5 to preheat the leather material.

[0018] The auxiliary molding mechanism includes an auxiliary mold cylinder 7, an auxiliary mold base 8, an air blowing cover plate 9, an auxiliary mold 10, a molding die 11, a molding die 11 base, a mold base guide post 13, a guide post spring 14, and a support plate 15. The working end of the auxiliary mold cylinder 7 is fixedly connected to the auxiliary mold base 8. The air blowing cover plate 9 is installed at the bottom of the auxiliary mold base 8. The auxiliary mold 10 is installed at the bottom of the air blowing cover plate 9. The molding die 11 is installed on the molding die 11 base. The molding die 11 base is installed on the mold base guide post 13 nested with the guide post spring 14. The mold base guide post 13 penetrates the bottom of the molding die 11 base and contacts the bottom of the molding die 11.

[0019] The transport mechanism includes a pull belt slide rail 1 and a pull belt clamp 2. The pull belt slide rail 1 is used to transport leather. The pull belt clamp 2 is set on the pull belt slide rail 1 and consists of upper and lower parts. When the pull belt clamp is activated, it clamps the leather in the middle and moves on the pull belt slide rail 1.

[0020] The second transport mechanism includes a second pull rail 19, a second pull clamp 17, and a fixed clamp 18. The second pull rail 19 consists of upper and lower parts. The fixed clamp 18 performs a releasing and clamping action. The first pull clamp 2 and the second pull clamp 17 simultaneously clamp the leather material. The leather material is pushed forward by moving from one end of the first pull rail 1 to the other end of the second pull rail 19 at a fixed distance, thus completing the preheating and forming of the leather material. During the movement, the fixed clamp 18 is in a released state. When the first pull clamp 2 and the second pull clamp 17 complete a pulling action, their upper and lower clamps will be in a released state and return to the initial position of the rail. At this time, the fixed clamp 18 starts to move, clamping and fixing the leather material. The punching equipment punches holes, completing a complete leather material pushing stroke.

[0021] The main function of the auxiliary molding device during operation is to help the leather material quickly and fully conform to the inner cavity of the mold, making the pocket forming more square and complete. This is especially beneficial for pockets with multi-ribbed or multi-cavity structures, resulting in more complete forming and higher strength. It effectively improves the forming effect and strength of carrier products with multiple cavities and deeper pockets. During forming, the leather material is subjected to pressure from the auxiliary mold 10, and the pressure during air blowing is more concentrated, which is beneficial for the leather to soften after heating and then blow-molding. The bottom of the pocket experiences uniform force, resulting in good forming effect and high strength after forming, making it less prone to deformation.

[0022] The system operates as follows: After the upper mold 4 and lower mold 5 are preheated to a certain temperature, this temperature is maintained by a temperature controller. The first and second pull-belt clamps 17 simultaneously clamp the leather material. The leather material is pushed forward by moving a fixed distance from one end of the pull-belt slide rail 11 to the other end of the pull-belt slide rail 29, thus completing the preheating and shaping of the leather. Specifically, the pull-belt clamp 2 pushes the leather material onto the lower mold 5. Under the action of the upper preheating cylinder 3, the upper preheating mold 4 moves downwards, while simultaneously, under the action of the lower preheating cylinder 6, the lower preheating mold 5 moves upwards. The upper and lower preheating molds 4 and 5 then close, clamping the leather material in between for heating and softening. The heated leather continues to move forward to the auxiliary forming mechanism. The second pull clamp 17 pushes the leather on the second pull rail 19 onto the forming die 11. The forming die 11 is mounted on the die base and connected to the die base guide post 13 and guide post spring 14. It reciprocates upwards via the bottom of the support plate 15. Simultaneously, under the action of the auxiliary die cylinder 7, the auxiliary die 10, mounted on the auxiliary die base 8, nests with the air-blowing cover plate 9 and moves downwards to close with the forming die 11. The auxiliary die 10 presses the softened leather into the cavity of the forming die 11, while simultaneously blowing air through the gap between the air-blowing cover plate 9 and the auxiliary die 10, causing the leather to quickly and fully adhere to the inner wall of the cavity on the forming die 11, forming a pocket consistent with the cavity of the forming die 11. Demolding is performed under the action of the ejector pin of the forming die 11. The second pull belt clamp 17 pushes the formed leather material out of the forming die 11 and continues to move forward intermittently to complete the pocket forming of the leather material. When the formed leather material passes through the punching system, the fixed clamp 18 is in a loose state during the movement. When the first pull belt clamp 2 and the second pull belt clamp 17 complete a pull belt action, their upper and lower clamps will be in a loose state and return to the initial position of the slide rail. At this time, the fixed clamp 18 starts to move, clamping and fixing the leather material. The punching equipment punches holes, completing a complete leather material pushing stroke. The punch press punches holes. After punching, it continues to move forward for slitting and product winding.
