Description

Technical Field

[0001] This application relates to the field of material production technology, and in particular to a material positioning and clamping structure. Background Technology

[0002] Materials refer to all kinds of raw materials required in the production, manufacturing, or service process. In the production of materials in the food category, cutting fruits in half and removing the pits is a common step, such as in dried fruit, dried apples, and dried apricots.

[0003] After the whole fruit is cut into two halves, the pit inside the half is exposed. Before the pitting process, the position of the half needs to be limited. In related technologies, the material limiting device uses two fixing parts. After the transfer device transports the half to the preset position, the two fixing parts move relative to each other from both sides of the half towards the half to clamp it, so that the pitting device can easily remove the pit from the inside of the half.

[0004] The above-mentioned limiting method of clamping the material with two fixed parts results in the fixed parts applying force to the fruit half during the movement. If the two fixed parts move asynchronously or the contact time of the clamping surfaces is inconsistent, the fruit half will be subjected to uneven force, generating lateral torque and popping out, which affects production efficiency. Summary of the Invention

[0005] To address the problem of uneven force distribution on the fruit half caused by two fixed parts clamping the material, resulting in lateral torque and ejection, thus affecting production efficiency, this application provides a material positioning and clamping structure with the following technical solution: It includes a mounting frame with a limiting device and a positioning device. The limiting device includes a support unit and a limiting unit mounted on the mounting frame. The mounting frame also has a drive unit that drives the support unit and the limiting unit to move relative to or away from each other. A limiting space is formed between the support unit and the limiting unit. The fruit half is supported on the support unit, and the positioning device pushes and positions the fruit half within the limiting space.

[0006] In one specific implementation, the positioning device includes a push rod disposed on a mounting frame, and the mounting frame is provided with a first driving part that drives the push rod to move. The first driving part uses the push rod to push and position the half of the fruit within the limiting space.

[0007] In one specific implementation, the push rod has a groove on its end face facing the limiting space that matches the half of the fruit.

[0008] In one specific implementation, the support unit includes a first frame disposed on the drive unit, the first frame having a first stop block, the fruit half being supported on the first frame and the fruit half being located between the first stop block and the push rod.

[0009] In one specific implementation, the limiting unit includes a second connecting frame disposed on the driving unit, the second connecting frame being provided with a second abutment, the push rod pushing and positioning half of the fruit between the first abutment and the second abutment, and the first abutment, the second abutment and the push rod forming a limiting space.

[0010] In one specific implementation, the first abutment block and the second abutment block are respectively provided with an embedding block, which is inserted into the inner cavity of the half of the fruit.

[0011] In one specific implementation, the drive unit includes a first moving frame and a second moving frame disposed on the mounting frame, the support unit and the limiting unit are respectively disposed on the first moving frame and the second moving frame, and the mounting frame is provided with a drive assembly for driving the first moving frame and / or the second moving frame to move.

[0012] In one specific implementation, the drive assembly includes a gear disposed on a mounting bracket, the mounting bracket having a second drive unit for driving the gear to rotate, a first rack disposed on a first moving bracket, a second rack disposed on a second moving bracket, the gear being located between the first rack and the second rack, and the gear meshing with the first rack and / or the second rack.

[0013] In one specific implementation, the mounting bracket is provided with a buffer unit, and the support unit or limiting unit is mounted on the drive unit through the buffer unit.

[0014] In one specific implementation, the buffer unit includes a telescopic cylinder disposed on the drive unit, and the first connecting frame is disposed at the output end of the telescopic cylinder.

[0015] In summary, this application has the following beneficial technical effects: When it is necessary to limit the position of the fruit half, the fruit half is placed on the support unit, and the drive unit is activated to move the support unit and the limiting unit relative to each other, thereby limiting the vertical position of the fruit half. Subsequently, the positioning device is activated to push and position the fruit half within the limiting space, thereby fixing the position of the fruit half. The vertical limiting is achieved through the coordinated movement of the support unit and the limiting unit, and the active pushing of the positioning device solves the problem of uneven force caused by asynchronous or contact time difference when clamping with traditional double fixed parts, reducing the risk of material ejection due to lateral torque. The three-way limiting fixation ensures the precise position of the fruit half in the pitting process, reduces the possibility of fruit half displacement, and improves the stability of the fruit half in the subsequent pitting process.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a material positioning and clamping structure.

[0023] Reference Figure 1 and Figure 2The material positioning and clamping structure includes a mounting frame 1, on which a limiting device and a positioning device are provided. The limiting device includes a support unit 2 and a limiting unit 3 mounted on the mounting frame 1. The mounting frame 1 is provided with a driving unit that drives the support unit 2 and the limiting unit 3 to move relative to or away from each other. A limiting space 4 is formed between the support unit 2 and the limiting unit 3. The fruit half is supported on the support unit 2, and the positioning device pushes and positions the fruit half within the limiting space 4. In this embodiment, the material positioning and clamping structure can be applied to food materials, such as yellow peaches and areca nuts. In this embodiment, areca nuts are cut into two pieces by a cutting process as an example.

[0024] Therefore, when it is necessary to limit the position of the fruit half, the fruit half is placed on the support unit 2, and the drive unit is activated to move the support unit 2 and the limiting unit 3 relative to each other, thereby limiting the vertical position of the fruit half. Then, the positioning device is activated to push and position the fruit half within the limiting space 4, thus fixing the position of the fruit half. The vertical limiting is achieved through the coordinated movement of the support unit 2 and the limiting unit 3. Combined with the active pushing of the positioning device, the problem of uneven force caused by asynchronous or contact time difference when clamping with traditional double fixed parts is solved. This reduces the risk of material popping out due to lateral torque. The three-way limiting fixation ensures the precise position of the fruit half in the pitting process, reduces the possibility of fruit half displacement, and improves the stability of the fruit half in the subsequent pitting process.

[0025] The drive unit simultaneously controls the support unit 2 and the limiting unit 3, and the mechanical linkage ensures synchronous movement. Compared with the independently controlled dual fixed parts in related technologies, this reduces the clamping asynchrony problem caused by electrical or mechanical delays. At the same time, the traditional dual fixed part clamping relies on the synchronization accuracy of both sides, which is prone to failure. This application achieves more reliable single-drive synchronous control and multi-directional force balance through a three-stage fixing of "support + limiting + active positioning". It is especially suitable for processing the half of easily rolling hemispherical fruits, such as the areca nuts used in the embodiments of this application.

[0026] Reference Figure 2 and Figure 3The positioning device includes a push rod 5 mounted on a mounting frame 1. The mounting frame 1 has a first driving unit that drives the push rod 5 to move. The first driving unit uses the push rod 5 to push and position the fruit half within a limiting space 4. A groove 6 matching the shape of the fruit half is formed on the end face of the push rod 5 facing the limiting space 4. In this embodiment, the first driving unit can be a cylinder, with the push rod 5 located at the cylinder's output end. A groove 6 matching the size of the areca nut slice is formed on the end face of the push rod 5 facing away from the first driving unit. The groove 6 can be arc-shaped according to the shape of the areca nut. The arc-shaped groove 6 limits the position of the areca nut slice, reducing the possibility of positional deviation. Simultaneously, the arc-shaped groove 6 adapts to the shape of the areca nut slice, reducing the possibility of the push rod 5 damaging the areca nut slice during movement.

[0027] Reference Figure 2 and Figure 3 The support unit 2 includes a first connecting frame 7 mounted on the drive unit, with a first abutment block 8 fixedly connected to the first connecting frame 7. The limiting unit 3 includes a second connecting frame 9 mounted on the drive unit, with a second abutment block 10 fixedly connected to the second connecting frame 9. The push rod 5 pushes and positions the fruit half between the first abutment block 8 and the second abutment block 10, and the first abutment block 8, the second abutment block 10, and the push rod 5 form a limiting space 4. In this embodiment, the number of the first abutment block 8 and the second abutment block 10 is set to two, but the number can also be set according to the actual situation on site, and is not limited here. An embedding block 11 is fixedly connected to the first abutment block 8 and the second abutment block 10, respectively. The embedding block 11 is inserted into the inner cavity of the fruit half, and the areca nut slice contacts the embedding block 11 and the embedding block 11 is embedded in the inner cavity of the areca nut slice. An inclined guide surface is provided on the end face of the embedded block 11 facing the limiting space 4. The inclined guide surface guides the embedded block 11 into the inner cavity of the betel nut slice, making it easy for the embedded block 11 to be smoothly inserted into the inner cavity of the betel nut slice.

[0028] In this embodiment, the example of embedding block 11 being embedded in the inner cavity of half of the fruit is used for illustration. In addition, depending on the actual situation on site, the first abutment block 8 and the embedding block 11 on the first abutment block 8 can be set as a curved bending block as a whole, and the second abutment block 10 and the embedding block 11 on the second abutment block 10 can be set as a curved bending block as a whole. By increasing the friction between the bending block and the inner cavity of the areca nut slice, the inner cavity of the areca nut slice can be further opened.

[0029] Therefore, the areca nut slices are mounted on the first connecting frame 7. The drive unit is activated to move the first connecting frame 7 and the second connecting frame 9 relative to each other, clamping the areca nut slices between the first connecting frame 7 and the second connecting frame 9, thereby limiting the vertical position of the areca nut slices. Then, the first drive unit is activated, causing the push rod 5 at the output end of the first drive unit to extend and push the areca nut slices against the first abutment block 8 and the second abutment block 10. At this time, the opening of the inner cavity of the areca nut slices faces the first abutment block 8 and the second abutment block 10. The first abutment block 8, the second abutment block 10 and the push rod 5 form a limiting space 4. The areca nut slices are pushed and positioned within the limiting space 4, thereby fixing the position of the areca nut slices.

[0030] Reference Figure 1 and Figure 4 The drive unit includes a first moving frame 12 and a second moving frame 13 mounted on the mounting frame 1. A support unit 2 and a limiting unit 3 are respectively mounted on the first moving frame 12 and the second moving frame 13. The mounting frame 1 is provided with a drive assembly for driving the first moving frame 12 and the second moving frame 13 to move. The drive assembly includes a gear 14 mounted on the mounting frame 1. The mounting frame 1 is provided with a second drive unit for driving the gear 14 to rotate. The second drive unit can be a drive motor. A first rack 15 is bolted to the first moving frame 12, and a second rack 16 is bolted to the second moving frame 13. The first rack 15 and the second rack 16 are arranged in parallel. The gear 14 is located between the first rack 15 and the second rack 16, and the gear 14 meshes with the first rack 15 and the second rack 16.

[0031] Therefore, the second drive unit is activated, causing the gear 14 at the output end of the second drive unit to rotate. The rotation of the gear 14 causes the first rack 15 and the second rack 16 to move relative to or away from each other, thereby causing the first moving frame 12 and the second moving frame 13 to move relative to or away from each other. When it is necessary to clamp the areca nut pieces, the second drive unit is activated, and the first moving frame 12 and the second moving frame 13 move relative to each other, so that the areca nut pieces are clamped between the first connecting frame 7 and the second connecting frame 9, thereby achieving vertical positioning of the areca nut pieces. In addition, in order to facilitate the subsequent process of removing the kernel from the areca nut pieces, since the embedding block 11 is embedded in the inner cavity of the fruit half, the second drive unit is activated again, and the first moving frame 12 and the second moving frame 13 respectively drive the first connecting frame 7 and the second connecting frame 9 to move away from each other, so that the embedding block 11 applies a force to the inner cavity of the areca nut pieces during the movement, thus opening up the inner cavity of the areca nut pieces.

[0032] Reference Figure 1 and Figure 4A buffer unit is provided on the mounting frame 1, and the support unit 2 or the limiting unit 3 is mounted on the drive unit through the buffer unit. The buffer unit includes a telescopic cylinder 17 mounted on the drive unit, and a first connecting frame 7 is mounted on the output end of the telescopic cylinder 17. In this embodiment, the telescopic cylinder 17 is mounted on the second moving frame 13, and the first connecting frame 7 is mounted on the output end of the telescopic cylinder 17. Therefore, the flexible contact of the buffer unit reduces hard collisions and reduces the possibility of damage to the surface of the areca nut during clamping. When the buffer unit uses the telescopic cylinder 17, after the areca nut pieces are fed, they abut against the first connecting frame 7 at the output end of the telescopic cylinder 17. When dealing with large areca nut pieces, the output end of the telescopic cylinder 17 will slightly retract under force, reducing the possibility of excessive compression of the areca nut.

[0033] The implementation principle of this application embodiment is as follows: Two areca nut pieces are respectively transported to the mounting frame 1 by a robotic arm in the feeding process. In related technologies, the moving end of the robotic arm in the feeding process uses a needle to pick up the areca nut pieces for transport. When it is necessary to limit the position of the fruit half, the second drive unit is activated, driving the gear 14 at the output end of the second drive unit to rotate. The rotation of the gear 14 drives the first rack 15 and the second rack 16 to move relative to each other, causing the first connecting frame 7 and the second connecting frame 9 to move relative to each other, so that the areca nut pieces are clamped between the first connecting frame 7 and the second connecting frame 9, thereby achieving vertical limitation of the areca nut pieces. The robotic arm in the feeding process drives the needle to pull out of the areca nut pieces, leaving the areca nut pieces between the first connecting frame 7 and the second connecting frame 9. Then, the first drive unit is activated, driving the push rod 5 at the output end of the first drive unit to extend, pushing and positioning the areca nut pieces against the first abutment block 8 and the second abutment block. On the abutment block 10, the opening of the inner cavity of the areca nut slice is positioned facing the first abutment block 8 and the second abutment block 10. The first abutment block 8, the second abutment block 10 and the push rod 5 form a limiting space 4. The areca nut slice is pushed and positioned within the limiting space 4, thus fixing the position of the areca nut slice. In addition, since the embedding block 11 is embedded in the inner cavity of the fruit half, the second drive unit is activated again. The first moving frame 12 and the second moving frame 13 drive the first connecting frame 7 and the second connecting frame 9 to move in opposite directions, so that the embedding block 11 applies force to the inner cavity of the areca nut slice during the movement, opening the inner cavity of the areca nut slice, thereby facilitating the subsequent pitting process to remove the pit from the inner cavity of the areca nut slice.

[0034] This application achieves vertical limiting through the coordinated movement of support unit 2 and limiting unit 3, combined with the active pushing of the positioning device. This solves the problem of uneven force caused by asynchrony or contact time difference in traditional double-fixed clamping, reducing the risk of material ejection due to lateral torque. The three-way limiting fixation ensures precise positioning of the fruit half during the pitting process, reducing the possibility of fruit half displacement and improving the stability of the fruit half in subsequent pitting processes. The drive unit simultaneously controls support unit 2 and limiting unit 3, and the mechanical linkage ensures synchronous movement. Compared with independently controlled double fixed parts in related technologies, this reduces the problem of clamping asynchrony caused by electrical or mechanical delays. At the same time, traditional double-fixed clamping relies on the synchronization accuracy of both sides, which is prone to failure. This application achieves more reliable single-drive synchronous control and multi-directional force balance through three-stage fixation of "support + limiting + active positioning", which is especially suitable for processing hemispherical areca nut blocks that are prone to rolling.
