Description

Technical Field

[0001] This utility model relates to the field of lock manufacturing equipment technology, and in particular to a combination wheel injection molding feeding device. Background Technology

[0002] Combination locks can be unlocked by rotating the combination wheel on the lock head to the correct code. No key is needed, and the unlocking number can be changed at any time. They are very convenient, highly secure, and therefore increasingly widely used.

[0003] Currently, two-color combination lock wheels on the market refer to combination lock wheels where the main body is one color, while the numbers on the outer circumference and the decorative rings on the sides are another color. During manufacturing, the main body of the combination lock wheel is typically injection molded first, and then a second injection molding process is performed to create structures of a different color in the number and decorative grooves. This second injection molding is usually done manually, using suction cups or a vibratory feeder to place each combination lock wheel into the positioning holes of the injection molding template. The template containing the combination lock wheels is then transported to the injection mold for injection molding. In actual production, this method is inefficient and unsuitable for mass production. Utility Model Content

[0004] The purpose of this invention is to provide a cipher wheel injection molding feeding device. This invention can feed multiple cipher wheels at once, which significantly improves production efficiency and is conducive to mass production operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a code wheel injection molding feeding device, comprising a vibratory feeder, a base, a material support, a pulling mechanism, a working platform, an injection positioning template, a top mechanism, and a pressing mechanism. The material support is connected to the base via a support column. Multiple material channels are arranged side-by-side on the material support. The vibratory feeder and the material support are connected via a direct vibration conveying track, allowing the code wheels on the vibratory feeder to be conveyed to their corresponding material channels. The working platform is positioned above the material support, and a positioning cover plate is provided on the working platform. A transmission channel for the injection positioning template to pass through is formed between the positioning cover plate and the working platform. The injection positioning template has multiple positioning holes for positioning the code wheels. The pulling mechanism is located on the side of the material support to move the code wheels to a position below each positioning hole on the injection positioning template. The top mechanism is located below the material support to fix the code wheels on the material support. The pressing mechanism is located above the positioning cover plate to cooperate with the top mechanism to transmit and position the code wheels in the positioning holes of the injection positioning template.

[0006] By adopting the above technical solution, the vibratory feeder feeds the code wheels. When the code wheels are conveyed to the material holder, the pulling mechanism moves the code wheels to the position below each positioning hole on the injection positioning template. The top and bottom pressing mechanisms clamp the code wheels on the material holder and move them into the positioning holes of the injection positioning template, realizing the feeding and positioning of multiple code wheels at one time. Finally, the injection positioning template with code wheels can be moved to the next process position by a cylinder or robot, etc., for injection molding or other processing operations.

[0007] The present invention is further configured such that the material pulling mechanism includes a horizontal displacement component, a vertical displacement component disposed on the movable end of the horizontal displacement component, and a plurality of material pulling rods disposed on the movable end of the vertical displacement component corresponding to the material channel.

[0008] By adopting the above technical solution, the pulling mechanism operates as follows: up-forward-down-back (pulling the code wheel) reciprocating motion, thereby moving the code wheel to the corresponding position.

[0009] The present invention is further configured such that the horizontal displacement component includes a drive motor, a lead screw, a nut, a slide rail, a slider, and a horizontal movable plate. The slider is disposed at the bottom of the lead screw and is slidably disposed on the slide rail in the direction of approaching or moving away from the material holder. The motor shaft of the drive motor is linked to the lead screw to drive the lead screw to rotate. The nut is installed on the horizontal movable plate and is threadedly engaged with the lead screw.

[0010] By adopting the above technical solution, the drive motor drives the lead screw to rotate, and the lead screw cooperates with the nut, thereby driving the horizontal movable plate to move towards or away from the material seat, thus realizing the forward and backward displacement of the material pulling mechanism. The structure is simple and the operation is stable.

[0011] The present invention is further configured such that the vertical displacement component includes a first cylinder and a vertical movable plate, the fixed end of the first cylinder is installed on the horizontal movable plate, multiple pull rods are installed at the bottom of the vertical movable plate, the horizontal movable plate is also provided with multiple guide posts, and the vertical movable plate is provided with multiple guide sleeves that cooperate with the guide posts.

[0012] By adopting the above technical solution, the vertical movable plate is raised and lowered by the first cylinder, thereby realizing the up and down displacement of the material pulling mechanism. The structure is simple and the action is fast. The stability of the vertical movable plate lifting process can also be improved by the combination of guide columns and guide sleeves.

[0013] The present invention is further configured such that the pull rod includes a pin for inserting into the center hole of the code wheel, a movable pressure sleeve that can be slidably disposed on the outer periphery of the pin along the axial direction, and a compression spring sleeved on the outer periphery of the pin for applying a downward preload to the movable pressure sleeve. The outer periphery of the pin is also provided with a limiting part for limiting the lower stroke of the movable pressure sleeve.

[0014] By adopting the above technical solution, when the pulling rod of the pulling mechanism moves downward and inserts into the center hole of the corresponding code wheel, the movable pressure sleeve moves upward relative to the pulling rod by a certain distance under the action of the code wheel, and the compression spring is compressed and stores energy; when the pulling rod moves upward, the movable pressure sleeve pushes the code wheel out of the pulling rod under the action of the compression spring, thereby realizing the pulling of the code wheel and ultimately the code wheel will not get stuck on the pulling rod.

[0015] The present invention is further configured such that multiple hollow guide strips are arranged side by side on the material base, and a material channel is formed between each two adjacent guide strips. Multiple sets of damping components for positioning the code wheel are arranged in the material channel. The set of damping components closest to the vibrating plate pre-positions the code wheel. The code wheel after pre-positioning is moved sequentially to the position of the corresponding damping component by the pulling mechanism for positioning.

[0016] By adopting the above technical solution, the damping component applies damping to the code wheel entering the material channel, hindering its displacement, thereby achieving the positioning of the code wheel at a specific position in the material channel, so as to facilitate its precise displacement in the future.

[0017] The present invention is further configured such that the damping assembly includes two damping blocks disposed on both sides of the material channel, and guide holes for the corresponding damping blocks to pass through are respectively opened on both sides of the material channel. The guide strip is provided with reset springs that apply outward preload to the damping blocks respectively, and the inner end of the damping block is also provided with a limiting flange for limiting the outer stroke of the damping block when it abuts against the inner wall of the guide strip.

[0018] By adopting the above technical solution, a retractable damping block acts on the outer periphery of the cipher wheel to keep it in a specific position. When a forced force is applied to the cipher wheel, it can be made to break free from the displacement of the damping block. The structure is simple and reliable, and is easy to assemble and produce.

[0019] The present invention is further configured such that two opposite damping blocks on each guide bar share a common return spring.

[0020] By adopting the above technical solution, not only is the use of return springs reduced, but the damping block and return spring also occupy less space.

[0021] The present invention is further configured such that the top mechanism includes a second cylinder, an ejector plate disposed on the extended end of the second cylinder, and a plurality of ejector rods disposed on the ejector plate; the material base is provided with a plurality of first through holes for the ejector rods to pass through; the pressing mechanism includes a third cylinder, a pressing plate disposed on the extended end of the third cylinder, and a plurality of pressing rods disposed on the pressing plate corresponding to the ejector rods; the positioning cover plate is provided with a plurality of second through holes for the pressing rods to pass through; the pressing rods and ejector rods clamp the corresponding code wheel and send the code wheel into the positioning hole of the injection molding positioning template.

[0022] By adopting the above technical solution, after the top rod of the top mechanism and the pressure rod of the bottom mechanism clamp the code wheel, the code wheel can be moved stably and accurately into the positioning hole of the injection positioning template.

[0023] The present invention is further configured such that the lower end of the pressure rod is provided with a positioning pin for passing through the center hole of the password wheel, and the upper end of the top rod is provided with a positioning groove that matches the positioning pin.

[0024] By adopting the above technical solution, the stability of the combination wheel when the top rod and pressure rod clamp it can be further improved, and the deviation of the combination wheel can be avoided so that it cannot be smoothly fed into the positioning hole of the injection positioning template.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example: As attached Figures 1-8The shown code wheel injection molding feeding device includes a vibratory feeder 1, a base 2, a material carrier 3, a material pulling mechanism 4, a working platform 5, an injection positioning template 6, a top mechanism 7, and a bottom pressing mechanism 8. The material carrier 3 is connected to the base 2 via a support column 9. Multiple material channels 10 are arranged side-by-side on the material carrier 3. The vibratory feeder 1 and the material carrier 3 are connected by a direct vibration conveying track 11, allowing the code wheels on the vibratory feeder 1 to be conveyed to the corresponding material channels 10. The working platform 5 is positioned above the material carrier 3 and is equipped with a positioning cover plate 12 (the positioning cover plate 12 is equipped with 8 M6 laser sensors for detecting the position of the code wheels). A transmission channel 13 is formed between the cover plate 12 and the working platform 5 for the injection positioning template 6 to pass through. The injection positioning template 6 can be fed into or out of the transmission channel 13 by a cylinder. The injection positioning template 6 is provided with a plurality of positioning holes 47 for positioning the code wheel. The material pulling mechanism 4 is set on the side of the material base 3 to move the code wheel to a position below each positioning hole 47 on the injection positioning template 6. The top mechanism 7 is set below the material base 3 to fix the code wheel on the material base 3. The pressing mechanism 8 is set above the positioning cover plate 12 to cooperate with the top mechanism 7 to transfer and position the code wheel in the positioning hole 47 of the injection positioning template 6. In this embodiment, there are 8 material channels 10 and 32 positioning holes 47 on the injection positioning template 6, that is, each positioning channel corresponds to 4 positioning holes 47. In addition, four side positioning holes are provided. Four positioning rods are provided on the pressing mechanism 8 to correspond to the positioning holes, so that when the pressing mechanism presses down, the positioning rods and positioning holes are engaged to calibrate the injection positioning template 6. The vibrating plate 1 feeds the code wheels. When the code wheels are conveyed to the material holder 3, the pulling mechanism 4 moves the code wheels to a position below each positioning hole 47 on the injection positioning template 6. The top mechanism 7 and the pressing mechanism 8 clamp the code wheels on the material holder 3 and move them into the positioning holes 47 of the injection positioning template 6, realizing the feeding and positioning of multiple code wheels at one time. Finally, the injection positioning template 6 with code wheels can be moved to the next process position by a cylinder or a robot, etc., for injection molding or other processing operations.

[0036] As attached Figure 3 As shown, the material pulling mechanism 4 includes a horizontal displacement component 14, a vertical displacement component 15 disposed on the movable end of the horizontal displacement component 14, and a plurality of material pulling rods 16 disposed on the movable end of the vertical displacement component 15 corresponding to the material channel 10. The material pulling mechanism 4 operates as follows: an up-forward-down-back (pulling the code wheel) reciprocating motion, thereby moving the code wheel to the corresponding position.

[0037] As attached Figure 3As shown, the horizontal displacement assembly 14 includes a drive motor 17, a lead screw 18, a nut 19, a slide rail 20, a slider 21, and a horizontal movable plate 22. The slider 21 is disposed at the bottom of the lead screw 18 and is slidably disposed on the slide rail 20 in the direction of approaching or moving away from the material holder 3. The motor shaft of the drive motor 17 is linked to the lead screw 18 to drive the lead screw 18 to rotate. The nut 19 is installed on the horizontal movable plate 22 and is threadedly engaged with the lead screw 18. The drive motor 17 drives the lead screw 18 to rotate, and the lead screw 18 engages with the nut 19, thereby driving the horizontal movable plate 22 to move in the direction of approaching or moving away from the material holder 3, thus realizing the forward and backward displacement of the material pulling mechanism 4. The structure is simple and the operation is stable.

[0038] As attached Figure 3 As shown, the vertical displacement assembly 15 includes a first cylinder 23 and a vertical movable plate 24. The fixed end of the first cylinder 23 is mounted on the horizontal movable plate 22. Multiple pulling rods 16 are mounted on the bottom of the vertical movable plate 24. The horizontal movable plate 22 is also provided with multiple guide posts 25, which extend vertically. The vertical movable plate 24 is provided with multiple guide sleeves 26 that cooperate with the guide posts 25. The first cylinder 23 drives the vertical movable plate 24 to rise and fall, thereby realizing the vertical displacement of the pulling mechanism 4. The structure is simple and the action is rapid. The cooperation structure of the guide posts 25 and guide sleeves 26 can also improve the stability of the vertical movable plate 24 during the rising and falling process.

[0039] As attached Figure 3 and attached Figure 4 As shown, the pull rod 16 includes a pin 27 for inserting into the center hole of the cipher wheel, a movable pressure sleeve 28 slidably disposed on the outer periphery of the pin 27, and a compression spring 29 sleeved on the outer periphery of the pin 27 for applying a downward preload to the movable pressure sleeve 28. The outer periphery of the pin 27 is also provided with a limiting part 30 for limiting the lower stroke of the movable pressure sleeve 28. When the pull rod 16 of the pull mechanism 4 descends and inserts into the center hole of the corresponding cipher wheel, the movable pressure sleeve 28 moves upward relative to the pull rod 16 a certain distance under the action of the cipher wheel, and then the compression spring 29 compresses and stores energy. When the pull rod 16 moves upward, the movable pressure sleeve 28 pushes the cipher wheel out of the pull rod 16 under the action of the compression spring 29, thereby pulling the cipher wheel and ensuring that the cipher wheel does not get stuck on the pull rod 16.

[0040] As attached Figure 5 and attached Figure 6As shown, multiple hollow guide strips 31 are arranged side by side on the material base 3. The guide strips 31 are fixed to the material base 3 with screws. Each pair of adjacent guide strips 31 forms a material channel 10. Multiple sets of damping components 32 for positioning the code wheel are arranged within the material channel 10. The set of damping components 32 closest to the vibrating plate 1 pre-positions the code wheel. The pulling mechanism 4 then sequentially moves the pre-positioned code wheel to the corresponding position of the subsequent damping component 32 for positioning. By applying damping to the code wheel entering the material channel 10 through the damping components 32, its displacement is hindered, thereby achieving the positioning of the code wheel at a specific location within the material channel 10, facilitating subsequent precise displacement.

[0041] As attached Figure 5 and attached Figure 6 As shown, the damping assembly 32 includes two damping blocks 33 disposed on both sides of the material channel 10. Guide holes 34 are respectively provided on both sides of the material channel 10 for the corresponding damping blocks 33 to pass through. The guide strip 31 contains return springs 35 that apply outward preload to the damping blocks 33. Furthermore, the inner end of each damping block 33 is provided with a limiting flange 36 that limits its outer travel when it abuts against the inner wall of the guide strip 31. The retractable damping blocks 33 act on the outer periphery of the cipher wheel, holding it in a specific position. Applying a force to the cipher wheel causes it to displace from the damping blocks 33. The structure is simple, reliable, and easy to assemble and produce.

[0042] As attached Figure 6 As shown, two opposing damping blocks 33 on each guide bar 31 share a single return spring 35. This design not only saves on the use of return springs 35, but also reduces the space occupied by the damping blocks 33 and return springs 35.

[0043] As attached Figure 5 and attached Figure 7 As shown, the top mechanism 7 includes a second cylinder 37, an ejector plate 38 disposed on the extended end of the second cylinder 37, and a plurality of ejector rods 39 disposed on the ejector plate 38. The material base 3 is provided with a plurality of first through holes 40 for the ejector rods 39 to pass through. The bottom pressing mechanism 8 includes a third cylinder 41, a bottom pressing plate 42 disposed on the extended end of the third cylinder 41, and a plurality of pressure rods 43 disposed on the bottom pressing plate 42 corresponding to the ejector rods 39. The positioning cover plate 12 is provided with a plurality of second through holes 44 for the pressure rods 43 to pass through. The pressure rods 43 and ejector rods 39 clamp the corresponding code wheel and send the code wheel into the positioning hole 47 of the injection molding positioning template 6. After the ejector rods 39 of the top mechanism 7 and the pressure rods 43 of the bottom pressing mechanism 8 clamp the code wheel, the code wheel can be moved stably and accurately into the positioning hole 47 of the injection molding positioning template 6.

[0044] As attached Figure 1and attached Figure 8 As shown, the lower end of the pressure rod 43 is provided with a positioning pin 45 for passing through the center hole of the code wheel, and the upper end of the top rod 39 is provided with a positioning groove 46 that matches the positioning pin 45. This design can further improve the stability of the code wheel when the top rod 39 and the pressure rod 43 clamp it, and prevent the code wheel from shifting and failing to be smoothly fed into the positioning hole 47 of the injection molding positioning template 6.
