Description

Technical Field

[0001] The utility model relates to the field of automation, in particular to a disc carrier fixture. Background Art

[0002] When moving a carrier, it needs to be clamped to prevent it from shaking during movement, thereby facilitating the positioning of the carrier and the workpiece it carries. Currently, commonly used clamps typically use cylinders to drive moving blocks on both sides to clamp or release. However, the cylinder's stroke is relatively fixed, making it difficult to adapt to carriers of different specifications.

[0003] In order to make the fixture suitable for carriers of different specifications, the power part can be adjusted from a cylinder to a motor. However, the motor-driven structure is relatively complex, resulting in a larger overall size of the fixture, which is difficult to meet the space requirements of the equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a disk holder which is applicable to disks of different specifications and has a small volume.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0006] A plate carrier fixture, comprising:

[0007] Power motor;

[0008] a support plate having a first side surface and a second side surface opposite to the first side surface, wherein the carrier plate is supported on the first side surface of the support plate;

[0009] The clamping assembly includes two groups of relatively arranged moving parts and a first sensor, the moving parts are used to clamp or release the carrier supported on the support plate, the moving parts include a clamping part, the clamping parts of the two moving parts both slide on the first side surface of the support plate, and synchronously approach or move away from the carrier under the drive of the power motor, the moving direction of the clamping part is a first direction, and a receiving groove parallel to the first direction is provided in the middle of the clamping part, the first sensor is provided in the receiving groove and connected to the support plate, the receiving groove is connected to the side of the clamping part close to the carrier through a sensing hole parallel to the first direction, and the first sensor is used to sense the position of the carrier.

[0010] Optionally, the plate carrier fixture further includes a synchronization component,

[0011] The synchronous assembly includes a first synchronous wheel, a second synchronous wheel and a synchronous belt. The first synchronous wheel is controllably rotated under the drive of the power motor, and the rotation direction is parallel to the support plate. The closed synchronous belt surrounds the first synchronous wheel and the second synchronous wheel to form a first belt segment and a second belt segment that are parallel to each other and move in opposite directions. The synchronous belt is arranged adjacent to the second side surface of the support plate.

[0012] The moving member also includes a connecting portion and a sliding portion. The sliding portion of the moving member is slidably connected to the first side surface of the support plate and is connected to the clamping portion through the connecting portion. The sliding portions of the two groups of moving members are respectively connected to the first belt segment and the second belt segment of the synchronous belt, so that the two groups of moving members move synchronously in opposite directions to clamp or release the carrier.

[0013] Optionally, the second side surface of the support plate is provided with a track groove and a wheel belt groove, the track groove cooperates with the sliding part of the movable member and is parallel to the moving direction of the movable member, one end of the track groove is connected to the edge of the movable member, the sliding part is inserted into the track groove and slides along the track groove, and the part of the sliding part corresponding to the track groove is completely embedded in the track groove, the wheel belt groove is used to accommodate the synchronous belt, and the part of the synchronous belt corresponding to the wheel belt groove is completely embedded in the wheel belt groove.

[0014] Optionally, a hollow groove perpendicular to the first band segment is formed in the middle of the first side surface of the support plate. The hollow groove is parallel to the support plate and passes through the support plate, and is used to move the carrier supported above the hollow groove from the bottom.

[0015] Optionally, the first belt segment and the second belt segment are accommodated in the same wheel belt groove, and the wheel belt groove is communicated with the hollow groove.

[0016] Optionally, the sliding portion of the moving member includes two sliding rods that are separated from each other and parallel to each other, and the sliding rods are configured in a long strip shape and connected to the connecting portion of the moving member.

[0017] Optionally, the disc carrier fixture further includes a bearing member and a fixed plate, the two bearing members being relatively arranged on both sides of the support plate for supporting the support plate, a through hole being provided on the bearing member at a position corresponding to the clamping portion of the movable member, the clamping portion passing through the through hole and moving controllably, the fixed plate being arranged on the side of any bearing member away from the support plate for supporting the power motor and the first synchronous wheel.

[0018] Optionally, the clamping portion expands at one end close to the carrier and is limited by the through hole to be located at a side of the carrier close to the support plate.

[0019] Optionally, the plate carrier fixture further includes a second sensor and a sensing plate, the second sensor is arranged on the fixed plate, the sensing plate is connected to the moving part close to the power motor, and the position of the sensing plate corresponds to the detection position of the second sensor, which is used to detect that the moving part has reached the initial position.

[0020] Optionally, the disc carrier clamp also includes a tensioning assembly, which includes a base plate, a sliding plate and a screw. The base plate is arranged on the other supporting member away from the fixed plate, and is arranged on the side of the supporting member away from the support plate. The sliding plate is supported on the base plate and slides on the base plate. One end of the sliding plate close to the supporting member protrudes laterally to form an adjustment platform. A screw hole parallel to the first band segment is formed on the adjustment platform. The screw passes through the screw hole and one end is rotatably connected to the supporting member. The second synchronous wheel is arranged on the sliding plate.

[0021] The beneficial effect of the present invention is that after the carrier plate is placed on the support plate, the first sensor senses the distance between the carrier plate and the first sensor, and the power motor drives the clamping portion of the moving member to move a distance corresponding to the detected distance, so that the clamping portions of both moving members contact the carrier plate. At this time, the carrier plate is fixed in the center of the support plate, thereby achieving centerline positioning and clamping of carrier plates of various specifications. The first sensor is positioned so as to be embedded in the clamping portion of the moving member and sense the position of the carrier plate through the sensing hole, which helps save space and reduce the volume, thereby meeting the space requirements of the equipment.

[0022] Furthermore, the synchronization component ensures that the two sets of moving parts operate synchronously, helping to ensure that the carrier is positioned in the center of the support plate. Integrating the synchronization component below the support plate helps to reduce the size of the carrier fixture, thereby meeting the space requirements of the equipment.

[0023] Furthermore, by slotting the support plate and partially embedding the sliding parts of the synchronous belt and the moving part in the slot, the structure is made more compact, and the disc carrier clamp is thinned, so that the thickness of most parts of the disc carrier clamp is only the thickness of the support plate, which helps to meet the overall spatial layout requirements of the equipment.

[0024] Furthermore, making a portion of the bottom of the carrier plate suspended in the air facilitates moving the carrier plate from the bottom.

[0025] Furthermore, the tyre groove is constructed as a wide groove that accommodates both the first and second tyre segments, facilitating adjustment and replacement of the tyre. Connecting the hollow groove with the tyre groove helps minimize the thickness of the support plate. The hollow groove also allows for observation of the tyre's operation from above, facilitating maintenance and adjustment of the structure.

[0026] Furthermore, the sliding portion includes two sliding rods, which helps to balance the force on the moving part, thereby improving the stability of movement.

[0027] Furthermore, the middle of the support plate is prone to interference with other mechanisms. Placing the supporting members connecting the entire disc carrier and the disc carrier on both sides of the support plate helps reduce the space occupied by the disc carrier and reduces the risk of interference. Placing the power motor on the side of the support plate through a fixing plate also facilitates spatial layout.

[0028] Furthermore, the expansion limit of the end portion of the clamping portion is located at the through hole, which helps to constrain the initial position of the moving part, helps to prevent the moving part from falling off, and helps to position the carrier plate at the center of the support plate.

[0029] Furthermore, detecting that the moving member reaches the outermost initial position by the second sensor helps to precisely control the movement of the moving member.

[0030] Furthermore, the distance between the sliding plate and the bearing member is adjusted by the screw rod, and the sliding direction of the sliding plate is constrained, thereby adjusting the distance between the second synchronous wheel and the first synchronous wheel, so that the wheel belt remains in a tensioned state.

[0031] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and to implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] See Figure 1 and Figure 2The disc carrier clamp claimed in the present application includes a support plate 11, a power motor 2, and a clamping assembly. The upper surface of the support plate 11 serves as a first side surface 111, and the lower surface serves as a second side surface 112. A disc carrier 101 is supported above the support plate 11. The clamping assembly includes two sets of opposing movable members 4 and a first sensor 5. The movable members 4 are used to clamp or release the disc carrier 101 supported on the support plate 11. The moving part 4 includes a clamping part 41. The clamping parts 41 of the two moving parts 4 both slide on the first side surface 111 of the support plate 11, and are synchronously approached or moved away from the carrier 101 under the drive of the power motor 2. The moving direction of the clamping part 41 is the first direction. A accommodating groove 412 parallel to the first direction is provided in the middle part of the clamping part 41. The first sensor 5 is provided in the accommodating groove 412 and is connected to the support plate 11. The accommodating groove 412 is connected to the side of the clamping part 41 close to the carrier 101 through a sensing hole 413 parallel to the first direction. The first sensor 5 is used to sense the position of the carrier 101.

[0040] After the carrier 101 is placed on the support plate 11, the first sensor senses the distance between the carrier 101 and the first sensor. The power motor 2 drives the clamping portion 41 of the moving member 4 to move a distance corresponding to the detection distance, so that the clamping portions 41 of the two moving members 4 are both in contact with the carrier 101. At this time, the carrier 101 is fixed in the center of the support plate 11, thereby achieving the centerline positioning and clamping fixation of carriers 101 of various specifications. The position of the first sensor 5 is set to be embedded in the clamping portion 41 of the moving member 4, and the position of the carrier 101 is sensed through the sensing hole 413, which helps to save space and reduce the volume, thereby meeting the space requirements of the equipment.

[0041] Please refer to the following examples for details.

[0042] Example 1:

[0043] See Figure 1 and Figure 2 The carrier clamp shown in a preferred embodiment of the present application includes a support assembly, a power motor 2, a synchronization assembly 3, and a clamping assembly. The support assembly is used to support the carrier 101 and other structures. The power motor provides power, causing the synchronization assembly 3 to drive the clamping assembly to clamp or release the carrier 101 in a first direction, thereby achieving positioning and fixing of the carrier 101. In this embodiment, the carrier 101 is a waffle plate.

[0044] The support assembly includes a support plate 11 , a bearing plate 12 , a fixing plate 13 and a tensioning assembly 14 .

[0045] The support plate 11 is arranged horizontally, with its upper surface as the first side surface 111 and the lower surface as the second side surface 112. The support plate 11 is constructed as a rectangle as a whole, and its two side surfaces perpendicular to the first direction are bearing surfaces. A horizontal hollow groove 113 perpendicular to the first direction is formed in the middle of the support plate 11. The hollow groove 113 is constructed in a rectangular shape and runs through the entire support plate 11. The length of the support plate 11 in the first direction matches the carrier 101 with the largest length, and the width of the hollow groove 113 in the first direction matches the carrier 101 with the smallest length, so that carriers 101 of different specifications can be fully supported on the first side surface 111 of the support plate 11, and it is convenient to move the carrier 101 from the bottom of the carrier 101 through the hollow groove 113.

[0046] This embodiment includes two vertically arranged support plates 12, each fixedly connected to the two support surfaces of the support plate 11. Two separate, downward-facing mounting feet 121 are located at the bottom of the support plates 12, connected to the ends of the support surfaces. The mounting feet 121 are higher than the first side surface 111 of the support plate 11, forming a rectangular through-hole connecting the two sides of the support plate 12.

[0047] The fixing plate 13 is horizontally connected to the side of a carrier plate 12 away from the support plate 11. The fixing plate 13 is fixedly connected above the through hole. The power motor 2 is fixedly connected to the edge of the fixing plate 13 away from the support plate 11, and the rotating shaft of the power motor 2 passes through the fixing plate 13 vertically downward. The lower surface of the fixing plate 13 is connected to a cylindrical first pulley 131, and the rotating shaft of the power motor 2 passes through the central axis of the first pulley 131.

[0048] The tensioning assembly 14 is connected to the supporting plate 12, which is further away from the fixed plate 13, and to the side of the supporting plate 12 away from the support plate 11. It includes a base plate 141, a sliding plate 142, and a screw 145. The base plate 141 is fixedly connected to the supporting plate 12 and faces the fixed plate 13. The base plate 141 is horizontal and shorter in the first direction than the fixed plate 13. The sliding plate 142 is horizontally supported above the base plate 141 and is longer in the first direction than the base plate 141. In other embodiments, the sliding plate 142 can be slidably connected to the base plate 141 in the first direction. One end of the sliding plate 142, which is closest to the supporting member, protrudes to form two rectangular adjustment platforms 143, which are spaced a certain distance from the supporting member. The adjustment platforms 143 have screw holes formed in the first direction. The screw 145 passes through the screw holes. One end of the screw is rotatably connected to the supporting member, while the other end expands into a cylindrical head. Rotating the head allows the position of the sliding plate 142 in the first direction to be adjusted. A second roller 144 is mounted at the bottom of the sliding plate 142. The second roller 144 is positioned on the side of the substrate 141 away from the carrier plate 12. When the sliding plate 142 slides against the carrier plate 12, the second roller 144 does not interfere with the substrate 141. The bottoms of the first and second rollers 131, 144 are flush and arranged parallel to the first direction. As the sliding plate 142 moves, the distance between the first and second rollers 131, 144 changes.

[0049] The synchronization assembly 3 includes a first synchronization wheel 31, a second synchronization wheel 32, and a synchronization belt 33. The first synchronization wheel 31 is rotationally connected to the first pulley 131 and to the rotating shaft of the power motor 2. Driven by the power motor 2, it rotates controllably along its central axis. The second synchronization wheel 32 has the same specifications as the first synchronization wheel 31 and is coaxially rotationally connected to the second pulley 144. The synchronization belt 33 surrounds the first and second synchronization wheels 31, 32. The two sections of the synchronization belt 33 located between the first and second synchronization wheels 31, 32 are respectively the first and second sections. The first and second sections are parallel to each other and move in opposite directions as the first synchronization wheel 31 rotates.

[0050] The clamping assembly includes two groups of relatively arranged moving parts 4, and the moving parts 4 include a clamping portion 41, a connecting portion 42 and a sliding portion. The clamping portion 41 is constructed in a horizontally arranged plate shape, and its main body is constructed in a rectangular shape, and passes through the through hole to reach the first side 111 of the support plate 11. The end of the clamping portion 41 close to the carrier 101 expands into a trapezoid, so that the clamping portion 41 cannot completely enter and exit the through hole, thereby preventing the clamping portion 41 from falling off the support plate 11. In other embodiments, the upper surfaces of the two clamping portions 41 are respectively slidably connected to the fixed plate 13 and the base plate 141. The side of the clamping portion 41 close to the carrier 101 is the contact surface 411 of the moving part 4, and the structure of the contact surface 411 is matched with the side of the carrier 101. The sliding portion includes two slide bars 431 separated from each other and parallel to each other, and a matching block 432 connected to any slide bar 431. The slide bar 431 is constructed as an elongated plate, parallel to the first direction and slidably connected to the second side surface 112 of the support plate 11. One of the slide bars 431 is fixedly connected to the side surface of the other slide bar 431 close to the matching block 432. A toothed groove 433 is formed on the matching block 432 to match the synchronous belt 33, and the matching blocks 432 of the two moving parts 4 are detachably connected to the first belt segment and the second belt segment of the synchronous belt 33 through the toothed groove 433, so that the sliding part of the moving part 4 moves parallel to the first direction and in the opposite direction with the synchronous belt 33, and the replacement of the synchronous belt 33 is convenient. The sliding part is fixedly connected to the end of the support rod away from the clamping part 41 and the end of the support rod away from the clamping part 41 by the connecting part 42, so that the contact surface 411 of the moving part 4 moves close to or away from the carrier 101 as the first synchronous wheel 31 rotates.

[0051] The movable member 4 also includes a first sensor. The first sensor is a photoelectric sensor, and its sensing direction is parallel to the first direction and toward the carrier 101. A accommodating groove 412 that cooperates with the first sensor is provided in the middle of the clamping portion 41 of the clamping assembly. The accommodating groove 412 is parallel to the first direction, and both ends thereof are located inside the clamping portion 41, and penetrate the clamping portion 41 in the vertical direction. One end of the accommodating groove 412 close to the contact surface 411 is connected to the contact surface 411 through the sensing hole 413, and the width of the sensing hole 413 is smaller than the accommodating groove 412. The two first sensors are respectively fixedly connected to the fixed plate 13 and the base plate 141, and are arranged in the accommodating groove 412. The first sensor senses the distance between the accommodating groove 413 and the carrier 101 through the sensing hole 413, thereby determining the moving stroke of the movable member 4. During the movement of the movable member 4, the position of the first sensor remains unchanged and is always located in the accommodating groove 412 of the clamping portion 41. The fixing plate 13 and the base plate 141 are respectively provided with circuit holes 132 at positions directly above the first sensor, for allowing circuits connected to the first sensor to pass through.

[0052] The clamping assembly in this embodiment also includes a sensing plate 6 and a second sensor 133. The second sensor 133 is a through-beam photoelectric sensor fixedly disposed above the fixed plate 13, with both the transmitting end and the receiving end parallel to the first direction. The sensing plate 6 is fixedly connected to the movable member 4 corresponding to the fixed plate 13 and slides therewith in the first direction. When the movable member 4 reaches its initial position away from the support plate 11, the sensing plate 6 is inserted between the transmitting end and the receiving end of the second sensor 133, thereby indicating the position of the movable member 4.

[0053] The second side surface 112 of the support plate 11 in this embodiment is provided with a track groove 114 and a wheel groove 115 .

[0054] The track groove 114 is parallel to the first direction, and its structure is matched with the slide bar 431, and extends from the edge of the support plate 11 to the middle. When the moving part slides to the maximum stroke, the end of the slide bar 431 contacts the end of the track groove 114. In this embodiment, the track groove 114 is enlarged near the edge of the support plate 11 and embedded in the constraint 7. A track is formed in the constraint 7 that matches the track groove 114 and the slide bar 431, which is used to constrain the freedom of the slide bar 431 in the vertical direction, and further prevent the moving part 4 from falling off. In this embodiment, the depth of the track groove 114 is not less than the thickness of the slide bar 431, which helps to reduce the thickness of the middle part of the carrier clamp, improve space utilization, and meet the equipment space requirements.

[0055] The wheel groove 115 is a rectangular long groove that matches the synchronous belt 33 and passes through the support plate 11 along the first direction. The depth of the wheel groove 115 is not less than the width of the synchronous belt 33. The middle part of the wheel groove 115 is connected to the hollow groove 113, so that the thickness of the support plate 11 reaches the minimum value and it is convenient to observe the operation of the synchronous belt 33 from above. A flexible buffer is provided on the side of the matching block 432 close to the support plate 11. When the moving part 4 reaches the maximum stroke, the buffer contacts the bearing surface of the support plate 11 to prevent the matching block 432 and the synchronous belt 33 from being impacted. The middle part of the wheel groove 115 is also connected to the bottom plate 8. The bottom plate 8 closes the bottom of the middle part of the wheel groove 115, supports the synchronous belt 33, and helps to suppress the loosening of the synchronous belt 33.

[0056] The beneficial effect of the present invention is that it can be matched with a variety of different sizes of carriers 101. After structural design, the carrier fixture has a relatively compact structure, a small thickness in the middle, and all components are exposed to the outside, which is convenient for overall maintenance and replacement of wearing parts.

[0057] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
