Description

Technical Field

[0001] This invention relates to the field of parts feeding technology, and in particular to a small material internal support feeding mechanism. Background Technology

[0002] In recent years, smart mobile terminal devices, such as mobile phones or tablets, have greatly changed people's lifestyles and have been integrated into people's daily lives, becoming an indispensable part of their daily routines. Consequently, the number of accessory products that accompany them has also increased, and the output of accessory product companies has also increased.

[0003] In the process of assembling products, component manufacturers need to use many small parts, such as brackets and buckles. Due to the characteristics of the products, when assembling components, it is necessary to grab the small parts and move them to the designated workstation. Traditionally, these parts are picked up manually. Currently, in order to improve production efficiency, machines are gradually being used to replace manual labor and implement fully automated picking. At this time, a small part picking mechanism is needed to automatically pick up the parts.

[0004] However, existing small material handling mechanisms on the market currently have limitations when gripping static bracket clips. Because the bracket clips are made of non-metallic materials, they cannot withstand large forces. Therefore, if the applied force is too large, the bracket clips are easily damaged. If the applied force is too small, the bracket clips are easily moved during the gripping process, resulting in low gripping stability. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that if the applied force is too large during the gripping process, the support buckle is easily damaged, and if the applied force is too small, the support buckle is easily moved during the gripping process. Therefore, this invention proposes a small material internal support material grabbing mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A small material internal support and material handling mechanism includes a housing, a pressing cylinder fixedly connected to the side wall of the housing, and further includes: a sliding frame slidably connected to the housing, the output end of the pressing cylinder being fixedly connected to the sliding frame; a pressure plate slidably connected to the bottom of the sliding frame, a spring connecting the pressure plate and the sliding frame, the pressure plate being able to press against a bracket buckle; and an outward expansion cylinder fixedly connected to the sliding frame, both output ends of the outward expansion cylinder being fixedly connected to gripping plates, the gripping plates being able to insert into the bracket buckle.

[0008] To improve downward stability, preferably, the device further includes: a slide plate slidably connected to the side wall of the slide frame, with the spring connecting the top of the slide plate to the slide frame; and a connecting plate fixedly connected to the bottom of the slide plate, with the pressure plate fixedly connected to the bottom of the connecting plate.

[0009] To prevent accidental detachment during gripping, preferably, anti-detachment blocks are provided on the sidewalls of the two gripping plates that are far apart from each other.

[0010] For ease of installation with other equipment, preferably, the top of the housing is fixedly connected to a mounting shaft, or the top of the housing is rotatably connected to a mounting shaft.

[0011] To achieve synchronous rotation and movement angle during material handling, preferably, when the top of the housing is rotatably connected to an installation shaft; a locking rod is fixedly connected to the sliding frame, the side wall of the installation shaft is provided with a groove, and the end of the locking rod away from the sliding frame is locked in the groove; the groove is composed of a straight groove and an arc groove, the straight groove is located below the arc groove, and the connection between the straight groove and the arc groove is a rounded transition.

[0012] To prevent the gripping plate from being overstretched, preferably, limit plates are fixedly connected to both sides of the bottom of the housing.

[0013] To adjust the distance the limiting plate can move, preferably, the limiting plate is threaded with an adjusting screw.

[0014] Preferably, a protective cover is fixedly connected to the bottom of the housing, and the limiting plate is fixed to both sides of the protective cover.

[0015] Preferably, the outward-expanding cylinder slides within the housing and protective cover.

[0016] To improve the stability of the sliding frame when it moves up and down, preferably, the side wall of the housing is provided with a sliding groove, and the sliding frame slides in the sliding groove.

[0017] Compared with the prior art, the present invention provides a small material internal support material handling mechanism, which has the following beneficial effects:

[0018] 1. This small material internal support material grabbing mechanism utilizes the compression characteristic of springs. During each material grabbing operation, when the pressure plate presses against the bracket buckle, the downward movement distance is controlled, causing the spring to be compressed to a certain extent each time. This addresses the problem of inaccurate force application during grabbing when the bracket buckle is in a static state, as the buckle cannot withstand large forces. By compressing the spring, the error value of the applied pressure during each grabbing operation is allowed to be within a larger range, greatly improving the stability of the grabbing operation.

[0019] 2. The small material internal support material picking mechanism fixes the pressure plate to the bottom of the slide plate through the connecting plate. The purpose is to allow the pressure plate to extend downward relative to the sliding frame, so as to better press the bracket buckle; at the same time, it also allows the two gripping plates to be located exactly in the notch in the middle of the bottom of the pressure plate.

[0020] 3. The small material internal support material picking mechanism, according to the usage scenario, controls the horizontal rotation angle of the bracket buckle by setting the shape of the arc groove, so as to match the usage requirements.

[0021] 4. The small material internal support material picking mechanism limits the movement distance of the two gripping plates by rotating the adjusting screw. Depending on the different models of bracket buckles, the movement distance of the two gripping plates can be flexibly limited. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Example 1:

[0034] Reference Figures 1-8 A small material internal support and material handling mechanism includes a housing 102, a clamping cylinder 2 fixedly connected to the side wall of the housing 102, and a sliding frame 201 slidably connected to the housing 102. The output end of the clamping cylinder 2 is fixedly connected to the sliding frame 201, and the clamping cylinder 2 pushes the sliding frame 201 to move vertically. A pressure plate 204 is slidably connected to the bottom of the sliding frame 201, and a spring 205 is connected between the pressure plate 204 and the sliding frame 201. The pressure plate 204 can press against the bracket buckle 1. Figure 2 The pressure plate 204 has a notch in the middle of its bottom. The bottom of the pressure plate 204 on both sides of the notch is designed to fit the top of the bracket buckle 1. The expansion cylinder 3 is fixedly connected to the sliding frame 201. Both output ends of the expansion cylinder 3 are fixedly connected to the gripping plate 301. The gripping plate 301 can be inserted into the bracket buckle 1. The two gripping plates 301 are always located in the notch in the middle of the bottom of the pressure plate 204.

[0035] The housing 102 is connected to an external moving device, such as a linear motor or a robotic arm.

[0036] When material needs to be picked up, such as by the bracket buckle, the entire picking mechanism is moved to directly above the bracket buckle 1 by the moving device. At this time, the clamping cylinder 2 is activated to push the sliding frame 201 downward until the pressure plate 204 presses on the bracket buckle 1 to prevent the bracket buckle 1 from moving during material picking. Then, the outward expansion cylinder 3 is activated to push the two gripping plates 301 to move horizontally to both sides from the inside out, that is, in the form of internal support, to contact the bracket buckle 1 and then apply a certain force to pick up the material. Then, the clamping cylinder 2 moves upward to achieve automatic material picking.

[0037] During the process of the pressing cylinder 2 pushing the sliding frame 201 to slide vertically downward, since the bracket buckle 1 is made of non-metallic material and cannot withstand large pressure, when the pressure plate 204 contacts the bracket buckle 1 and the sliding frame 201 continues to move downward, the spring 205 is compressed, and the pressure plate 204 can remain stationary to prevent the bracket buckle 1 from being crushed.

[0038] By utilizing the compression characteristic of spring 205, during each material handling process, when the clamping cylinder 2 pushes the sliding frame 201 downwards, causing the pressure plate 204 to press against the bracket buckle 1, the downward movement distance is controlled to ensure that spring 205 is compressed to a certain extent each time. This addresses the problem of inaccurate force application during gripping of the static bracket buckle 1, where the bracket buckle 1 cannot withstand large forces. By compressing spring 205, the error value of the applied pressure during each gripping is allowed to be within a larger range, greatly improving the stability of gripping.

[0039] This embodiment discloses a small material internal support material handling mechanism, which further includes: a slide plate 202 slidably connected to the side wall of the sliding frame 201; a spring 205 connected between the top of the slide plate 202 and the sliding frame 201; the slide plate 202 is stuck inside the sliding frame 201, can only move along the sliding frame 201, and cannot detach from the sliding frame 201; when the slide plate 202 is at its lowest position, such as... Figure 5 At this time, the spring 205 still applies a certain thrust, and the connecting plate 203 is fixedly connected to the bottom of the slide plate 202. The pressure plate 204 is fixedly connected to the bottom of the connecting plate 203, and the pressure plate 204 is detachably connected to the bottom of the connecting plate 203 by bolts.

[0040] The pressure plate 204 is fixed to the bottom of the slide plate 202 by the connecting plate 203. The purpose is to allow the pressure plate 204 to extend downward relative to the sliding frame 201, so as to better press down the bracket buckle 1; at the same time, it also allows the two gripping plates 301 to be located exactly in the notch in the middle of the bottom of the pressure plate 204.

[0041] The pressure plate 204 is detachably connected to the bottom of the connecting plate 203 by bolts. Different pressure plates 204 can be replaced with different models of bracket clips 1.

[0042] like Figure 7 Anti-detachment blocks 302 are provided on the side walls of the two gripping plates 301 that are far apart from each other.

[0043] When the expansion cylinder 3 is activated, it pushes the two gripping plates 301 to move horizontally to both sides and to come into contact with the bracket buckle 1. While picking up the material, the anti-detachment blocks 302 on the two gripping plates 301 will be locked in the bracket buckle 1 to prevent the bracket buckle 1 from accidentally falling off during the movement.

[0044] Once the device reaches its destination, the two gripping plates 301 are moved inward by the outward expansion cylinder 3. At this time, the anti-detachment block 302 will automatically disengage from the bracket buckle 1.

[0045] Example 2:

[0046] Reference Figure 1 and Figure 3 The present invention is basically the same as that in Example 1, but based on Example 1, a technical solution that is easy to install is further proposed.

[0047] A mounting shaft 101 is fixedly connected to the top of the housing 102.

[0048] The mounting shaft 101 is a circular rotating body, which facilitates connection with external moving devices or other components.

[0049] Example 3:

[0050] Reference Figure 1 , Figure 3 , Figure 8 Similar to Example 1, but based on Example 1, a technical solution is further proposed that allows for horizontal rotation at a certain technical angle during material handling.

[0051] The top of the housing 102 is rotatably connected to a mounting shaft 101, which is a circular rotating body.

[0052] A locking rod 501 is fixedly connected to the sliding frame 201. The side wall of the mounting shaft 101 is provided with a groove 5. The end of the locking rod 501 away from the sliding frame 201 is locked in the groove 5. The groove 5 is composed of a straight groove 502 and an arc groove 503. The straight groove 502 is located below the arc groove 503. The connection between the straight groove 502 and the arc groove 503 is a rounded transition.

[0053] During the material handling process, when the sliding frame 201 moves downward, the locking rod 501 slides into the straight groove 502 and continues to slide downward. At this time, the housing 102 will only move vertically downward to complete the material handling. After the material handling is completed, when the sliding frame 201 moves upward, the locking rod 501 slides into the arc groove 503. At this time, since the arc groove 503 is spiral, it will cause the locking rod 501 to rotate around the mounting shaft 101, which in turn drives the housing 102 to rotate around the mounting shaft 101, and drives the bracket buckle 1 to rotate together. This is suitable for some work scenarios where the bracket buckle 1 needs to be rotated after material handling.

[0054] Depending on the usage scenario, the shape of the arc groove 503 is set to control the horizontal rotation angle of the bracket buckle 1, so as to match the usage requirements.

[0055] Through this embodiment and Embodiment 2, that is, the top of the housing 102 is fixedly connected to the mounting shaft 101, or the top of the housing 102 is rotatably connected to the mounting shaft 101; there are two connection methods between the housing 102 and the mounting shaft 101, and the method can be flexibly determined according to the usage environment.

[0056] Example 4:

[0057] Reference Figures 1-8 The solution is basically the same as in Example 1, but the overall technical solution has been further optimized based on Example 1.

[0058] Limiting plates 4 are fixedly connected to both sides of the bottom of the housing 102.

[0059] The two gripping plates 301 are located between the two limiting plates 4. The limiting plates 4 can prevent the two gripping plates 301 from moving too far horizontally and damaging the bracket buckle 1.

[0060] The limiting plate 4 is threaded with an adjusting screw 401.

[0061] By rotating the adjusting screw 401, the movement distance of the two gripping plates 301 is limited. Depending on the different models of bracket clips 1, the movement distance of the two gripping plates 301 can be flexibly limited.

[0062] A protective cover 7 is fixedly connected to the bottom of the housing 102, and a limiting plate 4 is fixed on both sides of the protective cover 7; the outward expansion cylinder 3 slides inside the housing 102 and the protective cover 7.

[0063] With the housing 102 and protective cover 7, the outward-expanding cylinder 3 is prevented from being exposed when it moves with the sliding frame 201, thus improving safety.

[0064] The side wall of the housing 102 is provided with a sliding groove 6. The sliding frame 201 slides in the sliding groove 6. There are two sliding grooves 6. The sliding frame 201 is stuck in the sliding groove 6 and cannot be disengaged from the sliding groove 6, which improves the stability of the sliding frame 201 when sliding.

[0065] Finally, to gain a more intuitive understanding of the entire work process, the overall technical solution will be described once again:

[0066] When material needs to be picked up, the entire picking mechanism is moved to the top of the bracket buckle 1 by the moving device, the clamping cylinder 2 is activated, and the sliding frame 201 is pushed down until the pressure plate 204 presses on the bracket buckle 1 to prevent the bracket buckle 1 from moving when picking up material. Then the outward expansion cylinder 3 is activated to push the two gripping plates 301 to move horizontally to both sides and to stick to the bracket buckle 1. Then a certain force is applied to pick up material. Then the clamping cylinder 2 moves up to achieve automatic material picking.

[0067] When the pressure plate 204 contacts the bracket buckle 1, and the sliding frame 201 continues to move downward, the spring 205 is compressed, and the pressure plate 204 can remain stationary, preventing the bracket buckle 1 from being damaged. Through the compression characteristic of the spring 205, the spring 205 is compressed to a certain extent each time it is picked up. The compression of the spring 205 allows the error value of the applied pressure to be within a large range each time it is gripped, which greatly improves the stability of gripping.

[0068] The pressure plate 204 is fixed to the bottom of the slide plate 202 by the connecting plate 203, which makes it easier to press down the bracket buckle 1; at the same time, it also allows the two gripping plates 301 to be located exactly in the notch in the middle of the bottom of the pressure plate 204.

[0069] When the expansion cylinder 3 is activated, the two gripping plates 301 are pushed to move horizontally to both sides to pick up the material. At the same time, the anti-detachment blocks 302 on the two gripping plates 301 will be locked in the bracket buckle 1 to prevent the bracket buckle 1 from accidentally falling off during the movement.

[0070] During the material handling process, the horizontal rotation angle of the bracket buckle 1 is controlled by setting the shape of the arc groove 503 to match the usage requirements;

[0071] By rotating the adjusting screw 401, the movement distance of the two gripping plates 301 is limited. Depending on the different models of bracket clips 1, the movement distance of the two gripping plates 301 can be flexibly limited.

[0072] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
