Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and in particular to a disc changing and pitch-changing device. Background Technology

[0002] The manufacturing process of SIM card trays generally involves many steps, and different receiving trays or material trays need to be switched between different steps to load the SIM card trays. The spacing between the SIM card trays on different material trays is also different. Therefore, most of the time, the trays are manually removed one by one from the material tray of the previous step and placed into the material tray of the next step. This will cause fatigue to the operators due to the multiple product changes, which will easily lead to tray placement errors during the transfer process. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a tray-changing and spacing-adjusting device that can replace manual labor and ensure that the spacing between materials meets production requirements when switching between different trays.

[0004] To achieve the above objectives, the technical solution provided by the present invention is as follows: This invention provides a tray-changing and pitch-changing device, including a frame, a pitch-changing mechanism, and a first tray; a slidable positioning plate is provided inside the frame, the positioning plate being used for positioning and loading a second tray; the pitch-changing mechanism includes a transition plate, a baffle, and a pitch-changing guide plate slidably connected to the frame, the first tray being disposed on the top of the transition plate and forming a synchronous movement arrangement; the pitch-changing guide plate is slidably connected to the bottom of the transition plate away from the top of the frame and away from the first tray; the pitch-changing guide plate has pitch-changing guide channels arranged in an array, the baffle being movably inserted into the pitch-changing guide plate and laterally passing through each pitch-changing guide channel; both the first tray and the transition plate have material passage holes arranged in an array, and the first tray... The material tray and the transition plate have corresponding material passage holes; the baffle has arrayed clearance holes, and the relative position of the baffle and the variable pitch guide plate can be adjusted to switch between corresponding and staggered positions of the clearance holes and the variable pitch guide channel, thereby opening or closing the variable pitch guide channel; the relative position of the transition plate and the variable pitch guide plate can be adjusted so that the material passage hole of the transition plate can correspond to different variable pitch guide channels, and the variable pitch guide channel is opened only with the cooperation of the transition plate, so that the material on the first material tray can slide into the second material tray on the positioning plate by its own gravity through the material passage hole, the clearance hole and the variable pitch guide channel, thereby adjusting the placement spacing of the material on the second material tray.

[0005] Furthermore, the variable pitch guide plate is provided with a mounting groove for accommodating the baffle, the extension direction of the mounting groove intersects the extension direction of the variable pitch guide channel, and the mounting groove and the variable pitch guide channel are connected; the baffle is slidably inserted into the mounting groove.

[0006] Furthermore, a position adjustment assembly is provided between the transition plate and the pitch guide plate. The position adjustment assembly includes a mounting base, a movable rod, a spring, and an eccentric wheel. The mounting base is fitted onto the outer wall of the transition plate. The movable rod is movably inserted through the mounting base, with its first end connected to the pitch guide plate and its second end protruding from the mounting base on the side opposite to the pitch guide plate. The eccentric wheel is rotatably connected to the second end of the movable rod. The spring is sleeved on the movable rod and connected between the pitch guide plate and the mounting base. Rotating the eccentric wheel causes the movable rod to extend and retract laterally, thereby adjusting the relative position of the transition plate and the pitch guide plate in the lateral direction.

[0007] Furthermore, the extending direction of the mounting groove is perpendicular to the extending direction of the variable pitch guide channel.

[0008] Furthermore, the outer wall of the variable pitch guide plate is provided with a reset block for resetting the baffle; the reset block is provided with a reset groove, and the baffle is movably inserted into the reset groove to ensure that the baffle can be reset within the variable pitch guide plate.

[0009] Furthermore, the variable pitch guide channel includes an access groove and a variable pitch groove respectively disposed on the upper and lower sides of the mounting slide groove. The extension direction of the access groove is perpendicular to the baffle; the extension direction of the variable pitch groove is obliquely intersecting the extension direction of the access groove; the access groove is close to the transition plate, and the variable pitch groove is close to the positioning plate; and the adjacent opposite slots of the access groove and the variable pitch groove can simultaneously correspond to the clearance holes of the baffle, so that they are connected.

[0010] Furthermore, the upper opening of the access groove near the transition plate is trumpet-shaped; the inner wall of the variable pitch groove is an inclined wall structure.

[0011] Furthermore, there are two of each of the variable pitch guide plate, the baffle, the position adjustment component, and the reset block. Position adjustment components are respectively provided between the outer walls of the two variable pitch guide plates and the opposite ends of the transition plate. The variable pitch guide plate has two connected halves, and the inclined extension directions of the variable pitch grooves in the two halves are different.

[0012] Furthermore, the frame is provided with a positioning guide groove for accommodating the positioning plate, and the positioning plate is slidably mounted in the positioning guide groove.

[0013] Furthermore, the positioning plate is provided with a placement slot for accommodating multiple second material trays.

[0014] The technical solution provided by this invention has the following beneficial effects: The material on the first tray is slid into the second tray on the positioning plate by its own weight through the material passage hole, the clearance hole and the variable pitch guide channel via the variable pitch mechanism. This adjusts the spacing of the material on the second tray, thus realizing the variable pitch and tray switching of the material between different trays. Therefore, this invention can replace manual operation to quickly switch materials between different trays in the front and rear processes, effectively reduce the tray placement error rate, reduce the labor intensity of operators and save manpower.

[0016] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] Reference Figures 1 to 5This embodiment provides a tray-changing and pitch-changing device, including a frame 1, a pitch-changing mechanism 2, and a first tray 3. The pitch-changing mechanism 2 includes a transition plate 21, two adjacent pitch-changing guide plates 23, and two baffles 22 that cooperate with the pitch-changing guide plates 23. A positioning plate 4 for positioning and loading second trays 5 is provided within the frame 1. The positioning plate 4 is slidably mounted in a positioning guide groove 11 of the frame 1. The positioning plate 4 has a placement slot for accommodating several second trays 5 and is equipped with a handle structure. In this case, the first tray 3 is used to place materials 8 from the previous process (such as a mobile phone SIM card tray), and the second tray 5 is used to place materials 8 from the next process. Naturally, the bottom of the first tray 3 is provided with a foolproof positioning structure.

[0019] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the first material tray 3 is disposed on the top of the transition plate 21, and the first material tray 3 and the transition plate 21 are configured to move synchronously.

[0020] The tops of the two variable pitch guide plates 23 are slidably connected to the bottom of the transition plate 21 through a slide table and slide groove structure, and the bottoms of the two variable pitch guide plates 23 are slidably connected to the positioning slide groove 12 on the top of the frame 1.

[0021] Each pitch guide plate 23 has pitch guide channels 231 arranged in an array, and each baffle 22 is movably inserted into the corresponding pitch guide plate 23 and passes laterally through each pitch guide channel 231.

[0022] Each baffle 22 has an array of clearance holes 221, and the first material tray 3 and the transition plate 21 both have an array of material passage holes 211. The material passage holes 211 of the first material tray 3 and the transition plate 21 correspond one-to-one to ensure that the material passage holes 211 of the first material tray 3 and the transition plate 21 are always connected.

[0023] When each baffle 22 is pushed to slide laterally within each pitch guide plate 23, the lateral relative position of each baffle 22 and the corresponding pitch guide plate 23 can be adjusted, so that the clearance hole 221 of each baffle 22 and the corresponding pitch guide channel 231 can switch between corresponding and staggered positions, thereby opening or closing the pitch guide channel 231. When the clearance holes 221 of each baffle 22 and the corresponding variable pitch guide channels 231 are aligned with each other, the corresponding clearance holes 221, variable pitch guide channels 231, and the material passage holes 211 of the first material tray 3 and the transition plate 21 together constitute the material passage of the material 8, so that the material 8 on the first material tray 3 can slide down into the second material tray 5 by its own gravity through the material passage; when the clearance holes 221 of each baffle 22 and the corresponding variable pitch guide channels 231 are misaligned, the solid part of the baffle 22 can block the variable pitch guide channels 231, so that the material 8 falling from the first material tray 3 is blocked on the baffle 22 and cannot continue to slide down into the second material tray 5.

[0024] In summary, by adjusting the relative positions of the transition plate 21 and the variable pitch guide plate 23, the material passage hole 211 of the transition plate 21 can correspond to different variable pitch guide channels 231, and each variable pitch guide channel 231 is opened only with the cooperation of the transition plate 21, so that the material 8 on the first material tray 3 can slide into the second material tray 5 on the positioning plate 4 by its own gravity through the material hole 211, the clearance hole 221 and the variable pitch guide channel 231, thereby adjusting the placement spacing of the material 8 on the second material tray 5.

[0025] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, each of the two variable-pitch guide plates 23 is provided with a mounting groove 232 for accommodating a baffle 22, and the two baffles 22 are slidably inserted into their corresponding mounting grooves 232. Specifically, the extension direction (i.e., the transverse direction) of each mounting groove 232 is perpendicular or obliquely intersecting the extension direction (i.e., the vertical direction) of its corresponding variable-pitch guide channel 231. Furthermore, when the baffle 22 is pulled out, each mounting groove 232 and its corresponding variable-pitch guide channel 231 are connected.

[0026] Further preferred, such as Figure 1 , Figure 3 and Figure 5As shown, position adjustment components 6 are respectively provided between the transition plate 21 and the two variable pitch guide plates 23, and the two position adjustment components 6 are located at the left and right ends of the transition plate 21, respectively. The specific position adjustment components 6 include a mounting base 61, a movable rod 62, a spring 63, and an eccentric wheel 64. The mounting base 61 is assembled on the outer wall of the transition plate 21. The movable rod 62 is movably inserted through the mounting base 61, and the first end of the movable rod 62 is connected to the variable pitch guide plate 23. The second end of the movable rod 62 protrudes from the mounting base 61 away from the outer wall of the variable pitch guide plate 23. The eccentric wheel 64 is rotatably connected to the second end of the movable rod 62. At this time, the spring 63 is sleeved on the movable rod 62 and connected between the variable pitch guide plate 23 and the mounting base 61.

[0027] By rotating the eccentric wheel 64, the movable rod 62 is driven to extend and retract laterally, which in turn drives the variable pitch guide plate 23 to move laterally relative to the transition plate 21, thereby adjusting the relative position of the transition plate 21 and the variable pitch guide plate 23 in the lateral direction, so as to realize that the material passage hole 211 of the transition plate 21 corresponds to the variable pitch guide channel 231 with different arrangement.

[0028] In this specific embodiment, such as Figure 4 As shown, each pitch guide plate 23 has two connected halves 235, and each pitch guide channel 231 includes an access groove 233 and a pitch groove 234 respectively disposed on the upper and lower sides of the mounting slide 232.

[0029] like Figure 2 As shown, each access slot 233 is located near the transition plate 21. The upper opening of each access slot 233 near the transition plate 21 is trumpet-shaped, and the extension direction of each access slot 233 is perpendicular to the plane of the baffle 22. Each pitch groove 234 is located near the positioning plate 4, and the extension direction of each pitch groove 234 is inclined to intersect the extension direction of the access slot 233. The inclined extension directions of the pitch grooves 234 in the two halves 235 of the same pitch guide plate 23 are different. For example, the inner wall of the pitch groove 234 in one half 235 is inclined forward, and the inner wall of the pitch groove 234 in the other half 235 is inclined backward, so as to correspond to the changing of four independent second material trays 5, that is, to realize the changing of multiple second material trays 5 at one time, which can significantly improve production efficiency. Of course, in other embodiments, the variable pitch guide plate 23 may not need to be divided into two halves 235, and the tilting direction of all variable pitch grooves 234 may be the same, except that the number of corresponding second material trays 5 is reduced accordingly.

[0030] When each baffle 22 is switched to the open position, the adjacent relative slots of each inlet slot 233 and the variable pitch slot 234 can simultaneously correspond to the clearance hole 221 of the baffle 22, so that they are connected, thereby ensuring that the material 8 slides from the first material tray 3 to the second material tray 5.

[0031] When each baffle 22 is switched to the closed position, the adjacent relative slots of each inlet slot 233 and the variable pitch slot 234 are all staggered from the clearance hole 221 of the baffle 22, so that they are not connected. This ensures that the material 8 sliding down from the first material tray 3 is directly blocked by the baffle 22. Then, the material 8 is placed into the material passage hole 211 of the first material tray 3 by a robot or manually. After all the material 8 is loaded into the first material tray 3, the relative position between the variable pitch guide plate 23 and the transition plate 21 is readjusted, and then the baffle 22 is removed, so that the material 8 continues to slide into the preset second material tray 5.

[0032] Therefore, by means of the pitch-changing mechanism 2, the material 8 on the first tray 3 is slid down by its own weight through the material hole 211, the clearance hole 221 and the pitch-changing guide channel 231 into the second tray 5 on the positioning plate 4, thereby adjusting the spacing of the material 8 on the second tray 5, that is, realizing the pitch change and tray switching of the material 8 between different trays. Therefore, this embodiment can replace manual operation to quickly switch the material 8 between different trays in the front and rear processes, and can also effectively reduce the tray placement error rate, while reducing the labor intensity of operators and saving manpower.

[0033] Of course, in other embodiments, the number of pitch guide plate 23, baffle 22 and position adjustment component 6 may also be one, which will not be described in detail here. The pitch guide plate 23 can also be driven to move laterally relative to the transition plate 21 by means of a lead screw motor or cylinder.

[0034] Further preferred, such as Figure 3 As shown, each variable pitch guide plate 23 has a reset block 7 on its outer wall for resetting the corresponding baffle 22. Specifically, each reset block 7 has a reset groove 71, and each baffle 22 has a protruding reset part 222. When the reset part 222 of each baffle 22 is movably inserted into the corresponding reset groove 71, it can be ensured that each baffle 22 can be reset in the corresponding variable pitch guide plate 23, thereby facilitating the next plate-swing operation.

[0035] In addition, the disc changing pitch device of this embodiment also has the following advantages: 1. This embodiment can effectively solve the problem that existing jigs cannot convert materials from a vertical state to a horizontal state. Compared with the method of using complex automated equipment to transfer and arrange materials through multiple intermediate transfers, this embodiment adopts the structural characteristics of the product itself (i.e., the flat structure of the mobile phone card tray) and uses its own gravity for conversion. The overall structure is more compact and simple.

[0036] 2. This embodiment can replace the conversion in three directions (including lateral pitch change, longitudinal pitch change and horizontal reversal), which can greatly reduce the cost of the mechanism.

[0037] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
