Description

Technical Field

[0001] This specification relates to the field of conductive rod potting and demolding technology, and more specifically, to an automatic demolding device. Background Technology

[0002] Currently, the demolding method for high-precision products using potting sealant involves uniformly applying a large amount of silicone oil to the inner wall of a PTFE mold, placing the product inside the mold cavity, potting the sealant, and then ejecting the mold base and product from the cavity using a round rod after curing. The main disadvantages of this method are as follows: First, the PTFE mold has poor thermal conductivity, leading to significant differences in the curing rate of the adhesive during the curing process. This increases localized internal stress in the product, reducing its machinability and service life. Furthermore, PTFE is prone to deformation during use, resulting in poor reusability of the mold. First, the demolding cost is high; second, applying silicone oil to the inner wall of the cavity will cause silicone oil to seep into the product during the potting process, resulting in an oil film on the surface of the subsequent product, which is prone to adsorption and accumulation of friction and wear products during use, resulting in lower product quality and poor service performance; third, directly ejecting the product from the cavity with a rod can easily cause uneven stress on the product, resulting in deformation of the internal structure of the product, reducing product quality and structural consistency; fourth, all operations during the demolding process are performed manually, and product quality depends on the operator's experience, resulting in high dependence on personnel, low efficiency, and low degree of automation. Summary of the Invention

[0003] The purpose of this specification is to provide an automatic demolding device that can overcome the aforementioned defects in the demolding of existing polytetrafluoroethylene molds.

[0004] The embodiments described in this specification are implemented as follows:

[0005] An automatic demolding device includes a device body, a separation mechanism, a demolding mechanism, and a product mold;

[0006] The product mold includes a support and a cylindrical mold. The support can block one end opening of the cylindrical mold. The product that abuts against the support is placed in the cavity formed by the cylindrical mold itself. The cylindrical mold is set on the main body of the device, and the movable direction of the cylindrical mold is different from the movable direction of the separation mechanism and the demolding mechanism.

[0007] The main body of the device is provided with several guide rails, and the direction of the several guide rails is consistent with the direction of the cylindrical mold toward the support.

[0008] The separation mechanism includes a first rocker assembly and a separation component. One end of the separation component is connected to the first rocker assembly, and the other end of the separation component can abut against one side of the support. The separation component can reciprocate linearly along the guide rail under the action of the first rocker assembly to separate the support and the cylindrical mold.

[0009] The demolding mechanism includes a second rocker assembly and a demolding component. One end of the demolding component is connected to the second rocker assembly, and the other end of the demolding component can act on the end of the product near the support. Under the action of the second rocker assembly, the demolding component performs linear reciprocating motion along the guide rail to separate the product mold and the product.

[0010] The embodiments described in this specification have at least the following advantages or beneficial effects:

[0011] Compared to existing technologies, this automatic demolding device uses guide rails on the main body to enable the separation mechanism and the demolding mechanism to perform linear reciprocating motion. Under this linear reciprocating motion, the separation mechanism separates the support from the cylindrical mold. At this point, the product is placed inside the cavity of the cylindrical mold. The demolding mechanism then ejects the product from the cylindrical mold, thus demolding it. Therefore, this automatic demolding device eliminates the need for silicone oil inside the product mold, effectively preventing oil film on the product surface and improving the demolding success rate. Furthermore, this automatic demolding device has a high degree of automation and requires less experience from operators, making it more practical. Attached Figure Description

[0027] Please refer to Figure 1 and Figure 7 An embodiment of the automatic demolding device provided in this specification includes a device body, a separation mechanism 11, a demolding mechanism 10, and a product mold 7;

[0028] The product mold 7 includes a support 24 and a cylindrical mold. The support 24 can block one end opening of the cylindrical mold. The product 13, which abuts against the support 24, is placed in the cavity formed by the cylindrical mold itself. The cylindrical mold is disposed on the main body of the device, and the movable direction of the cylindrical mold is different from the movable direction of the separation mechanism 11 and the demolding mechanism 10.

[0029] The main body of the device is provided with a plurality of guide rails 9, and the arrangement direction of the plurality of guide rails 9 is consistent with the direction of the cylindrical mold toward the support 24;

[0030] The separation mechanism 11 includes a first rocker assembly 6 and a separation member. One end of the separation member is connected to the first rocker assembly 6, and the other end of the separation member can abut against one side of the support 24. The separation member can reciprocate linearly along the guide rail 9 under the action of the first rocker assembly 6 to separate the support 24 and the cylindrical mold.

[0031] The demolding mechanism 10 includes a second rocker assembly 5 and a demolding component. One end of the demolding component is connected to the second rocker assembly 5, and the other end of the demolding component can act on the end of the product 13 near the support 24. Under the action of the second rocker assembly 5, the demolding component moves linearly back and forth along the guide rail 9 to separate the product mold 7 and the product 13.

[0032] It should be noted that the above-mentioned automatic demolding device can be used for at least the following products: 13

[0033] In this embodiment, the interior of product 13 consists of metal sheets with welded enameled wires, i.e., thin gold sheets, arranged in a fixed pattern. Product 13 is fixed within the cavity of product mold 7 by filling the mold with a curing agent. After demolding, product 13 includes the curing agent cured on its outer surface. The curing agent can be a resin or other materials.

[0034] In this embodiment, the main body of the device is formed by the cooperation of a first side plate, a second side plate, an upper protective cover 20, and a side protective cover 21 to form a box with a accommodating chamber. A first rocker assembly 6 and a second rocker assembly 5 are installed on the first side plate. The second side plate has through holes. Several guide rails 9 are provided on the side of the second side plate away from the first side plate. The first rocker assembly 6 is connected to the separating member (located on the side of the second side plate away from the first side plate) through the through holes. The second rocker assembly 5 is also connected to the demolding member (located on the side of the second side plate away from the first side plate) through the through holes. At this time, the separating member and the demolding member can slide along the guide rails 9, that is, to make linear reciprocating motion.

[0035] In this embodiment, a control unit 4 can also be provided on the first side plate. The control unit 4 can control the action sequence of the separating component and the demolding component by writing a program, so as to achieve the effect of separating the support 24 first and then separating the product 13.

[0036] In this embodiment, the support 24 and the cylindrical mold can be set to cylindrical and cylindrical shapes. Of course, in other embodiments, they can also be set to other shapes depending on the actual situation.

[0037] In this embodiment, the cylindrical mold is formed by the cooperation of male mold 23 and female mold 22. Male mold 23 and female mold 22 can be connected by snap-fit ​​and can also be integrally formed.

[0038] In addition, the movable direction of the cylindrical mold does not include the reciprocating motion direction of the separation mechanism 11 (which is consistent with the reciprocating motion direction of the demolding mechanism 10).

[0039] In this embodiment, the length direction of the guide rail 9 is the reciprocating motion direction of the separation mechanism 11 and the demolding mechanism 10. Therefore, the length direction of the guide rail 9 should be consistent with the channel direction of the cylindrical mold to achieve the effect of separating the support 24 and the product 13.

[0040] Based on the above, this automatic demolding device uses guide rails 9 on the main body of the device to enable the separation mechanism 11 and the demolding mechanism 10 to perform linear reciprocating motion. Under the action of the linear reciprocating motion, the separation mechanism 11 can separate the support 24 from the cylindrical mold. At this time, the product 13 is placed in the cavity of the cylindrical mold. Then, the demolding mechanism 10 pushes the product 13 out of the cylindrical mold to demold the product 13. It can be seen that the above-mentioned automatic demolding device does not require the use of silicone oil in the product mold 7, which can effectively avoid the presence of an oil film on the surface of the product 13 and improve the demolding success rate of the product 13. In addition, the above-mentioned automatic demolding device has a high degree of automation and requires less experience from the operator, making it more practical. In this embodiment, the main body of the device is provided with a first servo motor 3. The first rocker assembly 6 includes a first gear 61, a first connecting rod 62 and a first rocker 63 connected in sequence. The end of the first rocker 63 away from the first connecting rod 62 is connected to the separating member. The second rocker assembly 5 includes a second gear 51, a second connecting rod 52 and a second rocker 53 connected in sequence. The end of the second rocker 53 away from the second connecting rod 52 is connected to the demolding member. The first gear 61 meshes with the second gear 51. The first gear 61 or the second gear 51 is connected to the first servo motor 3. The first servo motor 3 can drive the first gear 61 or the second gear 51 to rotate.

[0041] In this embodiment, the height of the first rocker assembly 6 and the second rocker assembly 5 is consistent with the opening height of the through hole on the second side plate. That is, a heightening column / block can be provided on the first side plate so that the height of the first rocker assembly 6 and the second rocker assembly 5 is adapted to the height of the through hole.

[0042] In this embodiment, the first servo motor 3 can drive the second gear 51 to rotate, thereby driving the second connecting rod 52 on the second gear 51 to move. The second connecting rod 52 then drives the second rocker arm 53 to move. At this time, the demolding component set on the guide rail 9 can reciprocate linearly along the guide rail 9 under the drive of the second rocker arm 53. The reciprocating motion range of the demolding component includes the range of movement that ejects the product 13 from the cylindrical mold.

[0043] Similarly, the first gear 61 and the second gear 51 mesh, so when the first servo motor 3 drives the second gear 51 to rotate, the first gear 61 rotates, and the first gear 61 can drive the first connecting rod 62 to move, which in turn drives the first rocker arm 63 to move. The separating member can then reciprocate along the guide rail 9 under the drive of the first rocker arm 63. The reciprocating motion range of the separating member includes at least the range of movement required to separate the support 24 from the cylindrical mold.

[0044] In this embodiment, the first rocker arm 63 can be connected to the separator through the through hole, or it can be connected to the separator in the through hole. Similarly, a connecting block can be provided on the separator so that the connecting block passes through the through hole and is connected to the first rocker arm 63. Likewise, the second rocker arm 53 is set in the same way as the first rocker arm 63.

[0045] In this embodiment, the demolding component can be disposed on the sliding plate, and a groove adapted to the guide rail 9 is provided on the side of the sliding plate away from the demolding component. The second rocker arm 53 can be connected to the side of the sliding plate away from the demolding component. To improve kinetic energy, a counterweight can also be provided on the side of the sliding plate away from the demolding component.

[0046] In this embodiment, the coordination between the separating component and the demolding component can be adjusted by adjusting the reduction ratio of the first gear 61 and the second gear 51, thereby achieving the desired demolding effect of separating the support 24 first and then separating the product 13. For example, the reduction ratio of the first gear 61 to the second gear 51 is 2:1 (first gear to second gear). Here, the reduction ratio is sufficient to ensure that the motion cycles of the first gear and the second gear are integer multiples of each other.

[0047] In this embodiment, the size of the support 24 is larger than the size of the cylindrical mold. When the separating member reciprocates linearly along the guide rail 9, it can push the support 24 to move. Specifically, the diameter of the support 24 is larger than the outer diameter of the cylindrical mold, while the size of the separating member is between that of the support 24 and the cylindrical mold. Therefore, when the separating member reciprocates linearly, it can push the support 24 away from the cylindrical mold to achieve the effect of separating the support 24.

[0048] In this embodiment, a gap may be left between the separating component and the outer wall of the cylindrical mold to prevent the separating component from repeatedly rubbing against the cylindrical mold during movement.

[0049] In this embodiment, the demolding component is a cylindrical structure, and when the demolding component separates the product mold 7 and the product 13, it can abut against the outer edge of one end of the product 13.

[0050] Specifically, when the demolding component separates the product 13 from the product mold 7, the force applied by the demolding component to the outer edge of the product 13 can prevent the pushing force applied by the demolding component from being transmitted to the center of the curing agent, thereby preventing the pushing force from affecting the interior of the product 13.

[0051] Because the interior of product 13 contains a thin metal sheet with welded enameled wires (e.g., 0.295mm-0.305mm thick), it is highly susceptible to external forces, which can affect the quality of product 13. Specifically, the main function of the thin metal sheet is to transmit weak current and weak signals. Deformation caused by external forces can easily lead to changes in resistance, resulting in abnormal signal transmission.

[0052] Furthermore, the wall thickness of the demolding component can be determined based on the processing allowance of the curing agent on product 13 and the magnitude of the pushing force of the demolding component.

[0053] In this embodiment, the product mold 7 is made of copper. Copper is preferred for the product mold 7 because it has good thermal conductivity, effectively preventing uneven heat transfer that could lead to localized high stress, thereby improving the machinability of the product 13 and enhancing the reusability and lifespan of the product mold 7.

[0054] In this embodiment, the automatic demolding device further includes an ejection mechanism 1 disposed on the main body of the device. The ejection mechanism 1 includes a meshing second servo motor 2 and an ejection assembly. Under the action of the second servo motor 2, the ejection assembly can separate the product mold 7 after it has been separated from the product 13 from the main body of the device.

[0055] In this embodiment, an ejection mechanism 1 is provided on the first side plate, and the position of the ejection mechanism 1 corresponds to the position of the product mold 7. The ejection mechanism 1 and the product mold 7 are respectively provided on both sides of the second side plate.

[0056] In addition, the reduction ratio of the drive gear on the second servo motor 2 and the driven gear 19 in the ejection assembly can be adjusted to adjust the ejection frequency, thereby cooperating with the separation mechanism 11 and the demolding mechanism 10 to complete the entire automatic demolding process.

[0057] In this embodiment, the control unit 4 can adjust the order and frequency of engagement between the ejection assembly, the separation mechanism 11 and the demolding mechanism 10 by writing a program.

[0058] In this embodiment, the ejection assembly includes a base 16, a worm gear 14, several pairs of guide rods 15, several pairs of fixed rods, a movable plate, a compression spring 18, and an ejector pin 17.

[0059] The base 16 has a through groove, and one end of the worm gear 14 is connected to one side wall of the through groove, while the other end of the worm gear 14 passes through the other side wall of the through groove and meshes with the second servo motor 2.

[0060] The length direction of several pairs of fixed rods is the same as that of the worm gear 14, and the two ends of the fixed rods are respectively connected to the two opposite groove walls of the through groove;

[0061] The movable plate is inserted through the worm gear 14 and the fixed rod, and the movable plate can move along the length direction of the worm gear 14 under the action of the worm gear 14;

[0062] The compression spring 18 is sleeved on the fixed rod, and one end of the compression spring 18 is connected to the moving plate, while the other end of the compression spring 18 is connected to the groove wall away from the second servo motor 2.

[0063] The length direction of several pairs of guide rods 15 is consistent with the length direction of the worm gear 14, and the several pairs of guide rods 15 are symmetrically arranged on both sides of the worm gear 14. The several pairs of guide rods 15 pass through the groove wall away from the second servo motor 2 and are connected to the ejector pin 17. The ejector pin 17 can abut against the side wall of the product mold 7.

[0064] In this embodiment, the automatic demolding device further includes a feeding mechanism 8 disposed on the main body of the device. The feeding mechanism 8 is positioned corresponding to the demolding mechanism 10 and the separation mechanism 11. The feeding mechanism 8 is capable of mounting a plurality of the product molds 7.

[0065] In this embodiment, the feeding mechanism 8 has a space for placing the product mold 7, and the feeding mechanism 8 is located on the side of the second side plate away from the first side plate, corresponding to the setting position of the ejection component. This ensures that the ejector pin 17 ejects the product mold 7 from the placement space, while ensuring that the demolding component can act on the product 13 inside the cylindrical mold.

[0066] In this embodiment, the feeding mechanism 8 includes a base plate and a side cover. The base plate has an arc-shaped portion 12 adapted to the cylindrical mold and a straight plate portion. The arc-shaped portion 12 can abut against the cylindrical mold.

[0067] The length of the side cover is less than the length of the straight plate portion. The side cover and the straight plate portion cooperate to form a groove structure. The groove structure can place a plurality of the product molds 7 one by one along the length direction of the straight plate portion.

[0068] The base plate has a limiting groove, the channel direction of the limiting groove is the same as the setting direction of the base plate, the outer side wall of the product mold 7 is provided with a limiting block that matches the limiting groove, the base plate is connected to the product mold 7 through the snap-fit ​​action of the limiting groove and the limiting block, and the movable direction of the product mold 7 is the same as the length direction of the straight plate portion.

[0069] In this embodiment, there are two limiting grooves, namely the first limiting groove 121 and the second limiting groove 122. The first limiting groove 121 and the second limiting groove 122 can be symmetrically arranged on the outer side wall of the cylindrical mold, which can effectively improve the stability of the cylindrical mold.

[0070] In this embodiment, a base plate and a side cover are provided simultaneously. The base plate and the side cover cooperate to form a groove structure that is compatible with the product mold 7, which can further improve the feeding stability of the feeding mechanism 8, thereby increasing the demolding rate of the product and reducing the loss rate.

[0071] Moreover, the first limiting groove 121 and the second limiting groove 122 are U-shaped grooves, and their channel direction is the same as the setting direction of the base plate. At this time, the product mold 7 can slide down along the setting direction of the base plate under the action of gravity, without the need to set up an additional driving or action mechanism.

[0072] In this embodiment, the locking action of the limiting block and the limiting groove can prevent the product mold 7 from moving in the same direction when the demolding part ejects the product 13, and can also prevent the cylindrical mold from moving in the same direction when the separating part separates the support 24.

[0073] In this embodiment, the arc-shaped portion 12 and the straight plate portion can cooperate to form a J-shape, and the arc-shaped portion 12 is used to place the cylindrical mold.

[0074] In this embodiment, the arc-shaped part 12 can be adapted to the outer wall of the cylindrical mold, and the curvature of the arc-shaped part 12 can be adjusted to make the demolding process smoother.

[0075] In this embodiment, the shape of the separating member is consistent with the shape of the base plate. That is, the shape of the separating member can be set as J-shaped, the arc position is used to separate the support 24, and the straight position is convenient to set the sliding groove to ensure that it moves back and forth in a straight line along the guide rail 9.

[0076] The specific operating method of the automatic demolding device is as follows:

[0077] S1: A layer of high-temperature adhesive tape is pasted on the inner wall of the male mold 23 and the female mold 22, the male mold 23 and the female mold 22 are assembled into a cylindrical mold, and the cylindrical mold is placed on the support 24;

[0078] S2: Place the assembled product 13 to be demolded into the cavity of the product mold 7, pour the curing agent into the cavity of the product mold 7, and perform high-temperature curing according to the preset process and cool it with the furnace.

[0079] S3: The product mold 7 with product 13 is loaded into the feeding mechanism 8 in batches. At this time, the product mold 7 falls down to the bottom end (i.e., the arc part 12) along the feeding mechanism 8, and the limiting groove on the feeding mechanism 8 and the limiting block on the cylindrical mold are precisely limited.

[0080] S4: The second servo motor 2 drives the second rocker assembly 5 and the first rocker assembly 6 to move. The first rocker assembly 6 drives the separation mechanism 11 to reciprocate linearly to push out the support 24. The second rocker assembly 5 drives the demolding mechanism 10 to reciprocate linearly to push the product 13 out of the cylindrical mold, thus completing the demolding of the product 13.

[0081] S5: The active gear on the first servo motor 3 drives the driven gear 19 on the ejection mechanism 1 to move, and drives the ejector pin 17 to reciprocate linearly through the worm gear 14 to eject the cylindrical mold from the arc-shaped part 12, so that the cylindrical mold is separated from the main body of the device.

[0082] S6: The next product mold 7 with product 13 will automatically fall under the influence of gravity and repeat steps S4-S5.

[0083] The above are merely preferred embodiments of this specification and are not intended to limit this specification. Various modifications and variations can be made to this specification by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this specification should be included within the scope of protection of this specification.
