[0076] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0077] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0078] It should be noted that if a directional indication is involved in an embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0079] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0080] Metal parts for electronic products are small and require numerous machining surfaces. Some parts have six exterior surfaces, requiring machining. Currently, the most common machining method on the market relies on a combination of machining equipment and manual labor. The product is clamped in a fixture, obstructing some sides from being cut. After machining the remaining exposed sides, manual re-clamping is performed, and the remaining sides are machined. This solution requires manual loading during both clamping steps, resulting in high costs. Furthermore, each time the equipment is opened for re-clamping and positioning, process stability is compromised, leading to a linear increase in defects such as scratches and dimensional glitches.

[0081] Based on the above situation, it is necessary to develop a set of in-machine automated processing solutions to reduce manpower and save processing costs.

[0082] The present invention provides an automatic loading and unloading device, product surface processing equipment and a control method thereof. The automatic loading and unloading device designed to assist CNC machine tools can meet the requirements of automatic processing of six appearance surfaces of parts in the machine. With the help of the internal structure of the CNC machine tool, components can be replaced in all directions to achieve the purpose of fast, efficient and mass production.

[0083] Specifically, a three-axis CNC machine tool has a three-way movable main shaft, a four-axis CNC machine tool has a three-way movable main shaft and a rotary axis, and a five-axis CNC machine tool has a three-way movable main shaft and two rotary axes in different directions. The CNC machine tool corresponding to this application should be at least a four-axis CNC machine tool to meet the processing requirements.

[0084] Please refer to Figures 1 to 2The automatic loading and unloading device 100 includes a loading device 1 and a unloading device 2. The loading device 1 includes a first base 11, a feeding part 12 and a first holding part 13. The first base 11 is used to be fixed to the rotating shaft 230 of the CNC machine tool. The first base 11 is used to place the long material. The first holding part 13 is movably installed on the first base 11. During the movement of the first holding part 13, it has a holding position for pressing the surface of the long material and a loose position away from the long material. The feeding part 12 is movably arranged relative to the first base 11. The material portion 12 is used to drive the long material to move on the first base 11 so that part of the long material protrudes from the first base 11 to form a processing body; the blanking device 2 includes a second base 21 and a clamping structure 22. The second base 21 is used to be arranged on the workbench 210 of the CNC machine tool. The clamping structure 22 is arranged on the second base 21. The clamping structure 22 is used to receive and clamp the processing body processed and cut off by the CNC machine tool. The clamping structure 22 can be flipped in the up and down directions relative to the second base 21 to facilitate the blanking surface processing of the processing body.

[0085] In the technical solution of the present invention, the long material is placed on the first base 11. Initially, the first pressing part 13 is in the released position. The feeding part 12 drives the end of the long material to protrude from the first base 11, thereby forming a processing body. At this time, the first pressing part 13 switches to the pressing position to fix the long material, so that the processing body can remain relatively fixed with the first base 11. The spindle 220 of the CNC machine tool is equipped with a tool. Since the loading device 1 is carried by the rotating shaft 230 of the CNC machine tool, it can rotate as a whole following the rotating shaft 230, thereby facilitating the processing of the five surfaces of the processing body. After the processing is completed, the clamping structure 22 is flipped in the upper and lower directions, so that the clamping structure 22 can receive the processed processing body when it is located on the upper side. After the CNC machine tool controls the tool to cut the processing body, the processing body forms an independent part and is only subjected to the clamping force of the clamping structure 22. Flipping the clamping structure 22 can make the blanking surface exposed, so that the spindle 220 of the CNC machine tool can drive the tool to process the blanking surface. The loading and unloading of materials and the processing of six surfaces can all be completed automatically inside the CNC machine tool. The entire process does not require human intervention, thus achieving a fully automatic effect, high processing efficiency, and facilitating batch processing.

[0086] Specifically, the long material can be set as a bar material, extending longitudinally, and multiple bars can be set. Multiple bars are arranged side by side on the first base 11, and the feeding part 12 drives one end of the multiple bars to protrude from the first base 11, thereby forming multiple processing bodies arranged in the air. The multiple bars are fixed by the first holding part 13, so that the multiple processing bodies can be fixed. Since the processing body is suspended, except for the position where the processing body is connected to the bar material, the remaining five sides can be processed, and the spindle 220 of the CNC machine tool drives the tool to process the surface of the body. Processing. After the processing is completed, the clamping structure 22 is flipped over so that it can be adjacent to the loading device 1. At this time, the clamping structure 22 is opened to receive the processing body, and then the processing body is fixed. At this time, the bar is fixed by the clamping structure 22 and the first pressing part 13 at the same time, and the part of the processing body that needs to be cut off can be revealed. The spindle 220 of the CNC machine tool drives the tool to cut off the processing body. The flipping of the clamping structure 22 changes the direction of the blanking surface for easy processing. On the other hand, it can be staggered with the first base 11. After the six surfaces are processed, the finished parts are obtained.

[0087] It should be noted that in order to facilitate mass production and adapt to the differences in incoming materials, when multiple rods are arranged side by side on the first base 11, multiple first pressing parts 13 are correspondingly arranged and arranged side by side on the first base 11. Each first pressing part 13 fixes a rod, and multiple first pressing parts 13 can be driven synchronously to adapt to limited space.

[0088] It should be understood that, corresponding to different processing requirements of the product surface, the spindle 220 may switch tools multiple times during the processing of the processing body. At the same time, surface processing and truncation may be completed using different tools.

[0089] The present invention does not limit the specific structure of the first pressing portion 13. For example, the first pressing portion 13 may move linearly along the thickness direction of the first base 11, thereby loosening and pressing the material by lifting and falling. In this embodiment, please refer to Figures 3 to 5 The first pressing portion 13 includes a first pressing rod 131, which is rotatably mounted to the first base 11 via a first rotating shaft 10 extending laterally therefrom, forming a first pressing end 131a and a first driving end 131b, respectively, disposed on either side of the first rotating shaft 10. The feeding device 1 also includes a first driving structure 14, which drives the first driving end 131b to move, thereby causing the first pressing end 131a to swing, thereby switching between a release position and a pressing position. In other words, the first pressing rod 131 as a whole resembles a lever structure, with the first pressing end 131a swinging in an arc driven by the first driving end 131b, thereby pressing and releasing the material.

[0090] The first pressing rod 131 can extend in a straight line, but considering space issues, in some embodiments, the extension direction of the first pressing end 131a and the extension direction of the first driving end 131b are intersected, that is, the first pressing rod 131 is bent, and the first pressing end 131a and the first driving end 131b are arranged at an angle. In this way, the first pressing end 131a can be arranged on one side of the first base 11, and the first driving end 131b can be arranged on the other side of the first base 11. Please refer to Figure 4 and Figure 6 A through hole is provided on the first base 11 , and the first pressing end 131 a and the first driving end 131 b are respectively located on both sides of the through hole.

[0091] When multiple long materials are placed side by side, multiple first pressing parts 13 are arranged at intervals in the transverse direction, and the multiple first pressing parts 13 are all rotatably mounted via the first rotating shaft 10. This ensures that the multiple first pressing ends 131a are at the same pressing position on the multiple long materials, while reducing the number of parts and making the layout compact.

[0092] Specifically, in this embodiment, please refer to Figures 2 to 3 , multiple long materials are arranged side by side in the transverse direction, and the extension direction of the multiple first pressing ends 131a is the same as the extension direction of the long materials, and they all extend longitudinally. At this time, a discharge channel 1311 is formed on the first pressing end 131a, which passes through the first pressure rod 131 in the longitudinal direction. The discharge channel 1311 is used for the long materials to pass through. In this way, the end of the long material can be extended from the discharge channel 1311 while satisfying the pressure of the first pressing end 131a, thereby avoiding interference between the first pressure rod 131 and the long material.

[0093] Furthermore, when a plurality of first pressing portions 13 are arranged at intervals in the transverse direction, the first driving structure 14 drives the plurality of first pressing portions 13 to move synchronously, which can save space on the one hand and ensure the synchronization of the plurality of first pressing portions 13 on the other hand. Figure 6The first driving structure 14 includes a first cylinder 141 and a transmission structure. The first cylinder 141 is fixed to the first base 11, and the cylinder rod of the first cylinder 141 is arranged longitudinally; the transmission structure includes a push-pull seat 142 and a rocker arm 143. The two ends of the rocker arm 143 arranged in the transverse direction are rotatably connected with the push-pull seat 142 through a second rotating shaft 20 extending in the transverse direction. Specifically, the push-pull seat 142 has a certain size, and the second rotating shaft 20 extends in the transverse direction and is rotatably mounted on the push-pull seat 142. The two ends of the rocker arm 143 are bent so as to rotate with the second rotating shaft 20. At this time, the rocker arm 143 and the push-pull seat 142 can rotate relative to each other, and the push-pull seat 142 is fixed to the cylinder rod of the first cylinder 141. Multiple first driving ends 13 1b is passed through the rocker arm 143 and the push-pull seat 142, and an elongated hole 1310 is opened on the side of each first driving end 131b for the second rotating shaft 20 to pass through, wherein the first cylinder 141 drives the push-pull seat 142 to move. Under the limitation of the first rotating shaft 10 and the second rotating shaft 20, the push-pull seat 142 pushes the rocker arm 143 and the first driving end 131b to move a certain distance, and the rocker arm 143 swings to push multiple first driving ends 131b, so that the position of the second rotating shaft 20 in the elongated hole 1310 changes. At this time, multiple first driving ends 131b swing in an arc in the up and down directions, thereby driving multiple first holding ends 131a to swing around the first rotating shaft 10, realizing the conversion between the holding position and the release position. Through the cooperation of the push-pull seat 142 and the rocker arm 143, the linear drive of the first cylinder 141 is converted into the swing drive of the first drive end 131b, thereby adapting to the orientation relationship between the first drive end 131b and the first holding end 131a, and at the same time being able to meet the one-to-many drive requirements in a smaller space.

[0094] Specifically, the second rotating shaft 20 is configured as a stepped sliding pin.

[0095] Taking into account the errors in the incoming materials and the differences in their outer diameters, when the multiple first pressing ends 131a press the multiple materials with the same force and swing stroke, some of the first pressing ends 131a may contact the material surface, while some of the first pressing ends 131a may tilt and fail to perform the pressing function. In view of this, an elastic matching block 144 is provided on the side wall of the rocker arm 143. The elastic matching block 144 is used to press against the multiple first driving ends 131b. The elastic matching block 144 is made of an elastic material and can be deformed by pressure. During transmission, the elastic matching block 144 contacts all of the multiple first driving ends 131b. Therefore, when the rocker arm 143 swings and presses down the multiple first driving ends 131b, the elastic matching block 144 can be deformed and compressed by the reaction force of the multiple first driving ends 131b. The multiple pressing ends can adaptively press against the surfaces of multiple materials of different sizes under the elastic action of the elastic matching block 144. Accordingly, the deformation amounts of the corresponding multiple elastic matching blocks 144 corresponding to the multiple first driving ends 131b are different.

[0096] Specifically, the elastic matching block 144 can be sponge, silica gel, etc., which is not limited in the present invention.

[0097] Please refer to Figure 5 A plurality of partitions 145 are provided on the inner side of the rocker arm 143, and a receiving groove 1431 is defined between two adjacent partitions 145 and between the partition 145 and the end of the rocker arm 143. Each receiving groove 1431 is provided with a plurality of first driving ends 131b. A plurality of elastic fitting blocks 144 are provided and are respectively fixed to the bottom walls of the plurality of receiving grooves 1431. Each elastic fitting block 144 simultaneously presses the plurality of first driving ends 131b located in the corresponding receiving groove 1431. The rocker arm 143 is divided into a plurality of accommodating grooves 1431 by the partition 145, thereby dividing the plurality of first pressure rods 131. In this embodiment, two first driving ends 131b are set in each accommodating groove 1431, that is, each elastic matching block 144 corresponds to two first driving ends 131b. Since the plurality of first driving ends 131b are all matched through the second rotating shaft 20, during the movement, the plurality of first driving ends 131b are easy to move in the extension direction of the first rotating shaft 10, and there is a risk of movement jamming. Through the division setting of the accommodating grooves 1431, the matching accuracy between components is easier to ensure.

[0098] Furthermore, the portion of the first pressing portion 13 that is in contact with the elongated material is serrated, thereby ensuring a pressing effect. Such a configuration can adapt to materials of all sizes and shapes.

[0099] Specifically, the processing body is suspended. In order to prevent the processing body from deflecting horizontally during the processing, a contour groove 111 is provided on the edge of the first base 11 for adapting to the surface of the elongated material, thereby providing contour support for the processing body and facilitating guidance and positioning.

[0100] It should be understood that when the first pressing end 131 a is provided with a discharge channel 1311 , the discharge channel 1311 should be in communication with the contoured groove 111 .

[0101] In order to facilitate the linear guidance of material feeding, the first base 11 is provided with a feeding channel 112 extending in the longitudinal direction for accommodating long materials;

[0102] For example, a through groove extending in the longitudinal direction can be provided on the first base 11, and the through groove forms a feeding channel 112 for placing long materials. Alternatively, a plurality of strip blocks can be provided on the first base 11, and a feeding channel 112 is defined between two adjacent strip blocks for placing long materials. It should be understood that, at this time, the feeding channel 112 should be connected to the discharge channel 1311.

[0103] The present invention does not limit the specific structural form of the feeding part 12. It can be that an active rotating roller is set on the first base 11, and the long material is placed above the roller, and can be fed forward during the rotation of the roller. In this embodiment, please refer to Figure 2 The feeding part 12 is used to be detachably mounted on the spindle 220 of the CNC machine tool so as to be able to push the elongated material along the feeding channel 112. In this case, the feeding part 12 is a push plate. As an optional component, the spindle 220 of the CNC machine tool can choose to connect the feeding part 12 or the tool. When the feeding part 12 is connected, the position drives the feeding part 12 to push the elongated material away from the end of the processing body, thereby realizing the loading action. When multiple elongated materials are arranged side by side, the size of the feeding part 12 can be set to cover multiple elongated materials, so that multiple elongated materials can be pushed and loaded at the same time under the drive of the spindle 220. It should be understood that when the spindle 220 is connected to the feeding part 12, the tool cannot be connected. Therefore, it is necessary to complete the feeding action and then replace the tool for surface processing. After completing the surface processing, it is necessary to switch back to the feeding part 12 for the loading action.

[0104] The present invention does not limit the specific form of the clamping structure 22, which can be a pneumatic finger, in which case the cylinder of the pneumatic finger can be directly driven to rotate, or a seat body with a suction nozzle and other structures. In some embodiments, please refer to Figures 7 and 8The clamping structure 22 includes a support seat 221 and at least one second pressing portion 222. One end of the support seat 221 is rotatably installed to the second base 21 along an axis extending laterally. The other end of the support seat 221 is provided with a mounting groove 221a. One of the side walls of the mounting groove 221a is open. During the movement of the support seat 221, the mounting groove 221a has a first position with the groove facing upward and a second position with the groove facing sideways. In the first position, it is used to receive the processing body. In the second position, it is used to support the processing of the blanking surface of the processing body. The second pressing portion 222 is movably installed to the support seat 221, and part of the second pressing portion 222 extends into the mounting groove 221a to press the processing body against the bottom wall of the mounting groove 221a. Specifically, the support seat 221 can rotate 90°. In the first position, the notch of the mounting groove 221a faces upward, and the open side of the mounting groove 221a faces the loading device 1. The processing body can extend from the open side of the mounting groove 221a into the mounting groove 221a, thereby being pressed against the bottom wall of the mounting groove 221a by the second pressing portion 222. At this time, the processing body is placed horizontally. The pressing state of the second pressing portion 222 is maintained. After the processing body is cut off, the support seat 221 flips to the second position. At this time, the open side of the mounting groove 221a faces upward, that is, the processing body is placed vertically with the blanking surface facing upward, thereby facilitating tool processing. In this structure, the flipping is achieved by driving the support seat 221, which facilitates the setting of the driving structure. The second pressing portion 222 also has an installation and positioning basis. In the case of adapting multiple processing bodies, multiple second pressing portions 222 can be provided.

[0105] It should be noted that the number of the second pressing portions 222 may match the number of the processing bodies, or the second pressing portions 222 may press and fix a plurality of processing bodies.

[0106] The structure of the second pressing portion 222 is not limited and can be a linear pressing or a swinging pressing. In some embodiments, please refer to 8, the second pressing portion 222 includes a second pressing rod 2221 and a pressing block 2222. The second pressing rod 2221 is rotatably mounted to the support seat 221 via a third rotating shaft 30 extending laterally to form a second pressing end and a second driving end respectively arranged on both sides of the third rotating shaft 30; the pressing block 2222 is located in the mounting groove 221a and is connected to the second pressing end; the clamping structure 22 also includes a second cylinder 223 fixed to the support seat 221, and the cylinder rod of the second cylinder 223 is hinged to the second driving end to drive the pressing block 2222 to move toward or away from the bottom wall of the mounting groove 221a. When the cylinder rod of the second cylinder 223 extends or retracts, based on the hinged cooperation, it can drive the second driving end to move without causing the swing interference of the second pressure rod 2221. The pressure block 2222 can tighten or loosen the processing body under the drive of the second holding end.

[0107] Specifically, considering that the pressure block 2222 and the second pressing end both have a certain length, the third rotating shaft 30 is located on the outside of the mounting groove 221a and is staggered with the mounting groove 221a, and is fixed by two supports. The extension direction of the mounting groove 221a and the third rotating shaft 30 is the same. The pressure block 2222 and the second pressing end can be connected by screw locking, plug-in fitting, shaft hole fitting, etc. The second driving end forms a connecting rod fitting with the cylinder rod of the second cylinder 223. By reasonably setting the position of the third rotating shaft 30, the movable stroke of the second pressing end can be controlled.

[0108] Furthermore, the pressing block 2222 is used to press and hold multiple processing bodies. The pressing block 2222 is connected to the second pressing rod 2221 in a floating manner so that it can swing relative to the second pressing rod 2221 under the action of an external force. When the pressing block 2222 abuts against the surface of the processing body, it is subjected to the reaction force of the processing body, and the pressing block 2222 can float relative to the second pressing rod 2221, thereby being able to adapt to the processing errors of different processing bodies. When multiple second pressing rods 2221 are provided and connected by the same third rotating shaft 30, this floating installation form is conducive to ensuring that multiple pressing blocks 22 22 can ensure contact with the surface of the corresponding processing body, and there will be no situation where some of the pressure blocks 2222 are raised and cannot play the pressing function due to the difference in size of the multiple processing bodies. At the same time, when each pressure block 2222 corresponds to pressing multiple processing bodies, the floating matching form can also make the pressure block 2222 adaptively tilt in the downward direction after it is against the processing body, thereby ensuring that it is fixed against the surfaces of multiple processing bodies. Taking into account stability and floating principles, each pressure block 2222 is in contact and cooperate with at most two processing bodies.

[0109] In this embodiment, a card slot is provided at the second pressing end, and the end of the pressing block 2222 is installed in the card slot through a positioning pin. By reasonably setting the hole gap of the positioning pin, the pressing block 2222 can have a certain swing stroke, thereby achieving the purpose of floating fit. In other embodiments, the pressing block 2222 can also be connected to the second pressing rod 2221 through a spring to achieve a floating effect, and the present invention does not limit this.

[0110] Furthermore, a flexible member 224 is provided on the side of the pressing block 2222 facing the bottom surface of the mounting groove 221a. The flexible member 224 can be made of sponge or silicone. The flexible member 224 can be squeezed and deformed when in contact with the processing body, which can not only protect the processing body and reduce scratches, but also adapt to the size differences of multiple processing bodies and improve the holding effect.

[0111] In an embodiment of the present invention, the pressing block 2222 is divided into a hard part and a soft part. The hard part is floatingly connected to the second holding end, and the soft part is in contact with the surface of the processing body. The two parts can be combined into one by bonding or other means.

[0112] Furthermore, mounting groove 221a houses a contoured support block 23 adapted to conform to the surface of the machined workpiece after machining. This block cooperates with second holding portion 222 to secure the workpiece. This contoured support block 23 provides positioning support, enhancing the holding effect by conforming to the workpiece's surface. This prevents the workpiece, which has already had five surfaces machined, from shaking during the blanking process, thus avoiding surface damage and ensuring accurate machining of the blanking surface.

[0113] Specifically, the contoured support block 23 achieves the contoured support effect by providing a contoured groove structure on the surface. When multiple processing bodies are provided, multiple groove structures are provided accordingly.

[0114] The contoured support block 23 is an independent structure that is separately added and made of a material different from or the same as that of the support seat 221. When processing a different product, only the contoured support block 23 needs to be replaced to adapt to the new product.

[0115] Furthermore, the support base 221 is also provided with an air blowing structure 24, the outlet of which corresponds to the mounting slot 221a. The air blowing structure 24 is connected to an external air pump structure and can blow air into the mounting slot 221a. On the one hand, it can blow out the debris in the mounting slot 221a during the processing, and on the other hand, it can be used to drop the finished parts by blowing. Specifically, due to the small size and light weight of the product, by properly setting the direction of the air outlet and the air flow rate, the finished parts can be blown out of the mounting slot 221a.

[0116] The present invention does not limit the specific form of flipping of the support seat 221. In some instances, a flip cylinder can be directly set to achieve it, or it can be achieved by using a connecting rod. Considering that the use scenario of the device is in a CNC machine tool warehouse, in order to avoid blocking other parts, in this embodiment, the blanking device 2 also includes a flipping assembly 25. The flipping assembly 25 includes a third cylinder 251, a guide block 252 and a slider 253. The third cylinder 251 is fixed to the second base 21, and the cylinder rod of the third cylinder 251 extends longitudinally; the guide block 252 is fixed to the side of the support seat 221, and a guide hole 2521 extending laterally and inclined in the up and down directions is provided on the guide block 252. The slider 253 is fixed to the cylinder rod of the third cylinder 251, and a guide column 254 extending laterally is provided on the slider 253. The guide column 254 is movably inserted into the guide hole 2521. The cylinder rod of the third cylinder 251 extends and retracts, driving the slider 253 to perform linear motion in the longitudinal direction. Since the guide post 254 on the slider 253 is inserted into the guide hole 2521, the position of the guide post 254 within the guide hole 2521 changes during the movement of the slider 253. This, when in a specific position, causes the guide block 252 to swing, thereby driving the support base 221 to rotate about its extended axis. This structure converts the linear drive of the third cylinder 251 into a drive that causes the support base 221 to swing vertically about its rotation axis, thereby achieving a flipping effect. With this arrangement, the entire flip assembly 25 can be hidden beneath the support base 221 when it is in the second position, thereby achieving maximum utilization of space.

[0117] In order to improve the stability and swing stroke of the support seat 221 in the first position and the second position, in some embodiments, the blanking device 2 further includes a first positioning assembly, which includes a limit block 261 and a matching platform 262. The matching platform 262 is fixed to the second base 21 and is located on one side of the support seat 221 in the longitudinal direction. The limit block 261 is fixed to the side of the support seat 221 facing away from the guide block 252. When in the first position, the limit block 261 and the matching platform 262 are in contact with each other. The matching platform 262 is formed by a local upward protrusion of the second base 21. The matching platform 262 should have sufficient width to meet the support and limit effect. The upper end surface of the matching platform 262 should also ensure good flatness to match with the limit block 261. The limit block 261 can be set in a triangular structure to have good support strength and can also serve as a reinforcing rib of the support seat 221.

[0118] In order to improve the stability of the support seat 221 in the first position and the second position and to limit the swing stroke, in some embodiments, the blanking device 2 further includes a second positioning assembly, which includes a plurality of limiting struts 263 fixed to the second base 21. The plurality of limiting struts 263 are located on the other side of the support seat 221 in the longitudinal direction. In the second position, the plurality of limiting struts 263 abut against the side surface of the guide block 252 provided on the support seat 221. During the swinging process of the support seat 221, when the corresponding side surface of the support seat 221 abuts against the end surfaces of the plurality of limiting struts, a hard limit effect is achieved. At this time, the support seat 221 cannot continue to rotate. The plurality of limiting struts correspond to the plurality of positions of the support seat 221, thereby cooperating to achieve a load-bearing effect.

[0119] In this embodiment, the first positioning assembly and the second positioning assembly are provided simultaneously, and the turning stroke and position fixation of the support seat 221 are limited in combination with the automatic limit of the driving stroke of the third cylinder 251 and the mechanical hard limit.

[0120] The height of the slider 253 gradually decreases as it moves away from the loading device 1. Specifically, the slider 253 is lower on the side away from the end pivotally connected to the support base 221. This allows for the guide block 252 to be positioned in the second position, thus reducing the height gap. In this embodiment, the guide block 252 is tilted.

[0121] To reduce the height of the blanking device 2, please refer to Figure 7 and Figure 9 The second pressing part 222 is provided with multiple, and the clamping structure 22 also includes a plurality of second cylinders 223 fixed on the support seat 221. The plurality of second cylinders 223 are used to drive the second pressing part 222 to move, and a matching gap is formed between two adjacent second cylinders 223; the slider 253 includes two matching plates 2531 spaced laterally, and a guide column 254 is arranged between the two matching plates 2531. When in the second position, the matching plate 2531 is in the corresponding matching gap, and the guide column 254 and the plurality of second cylinders 223 are staggered. In this structure, the slider 253 is composed of two mating plates 2531 and a guide column 254 fixedly connecting the two mating plates 2531. When the support seat 221 is converted to the second position, as the second cylinder 223 and the slider 253 gradually approach each other, the mating plate 2531 can extend into the mating gap between the two adjacent second cylinders 223, so that after the support seat 221 is flipped into place, the second cylinder 223 and the mating plate 2531 are arranged in the horizontal direction to save space.

[0122] It should be noted that, considering the limited space, three second pressing parts 222 and three second cylinders 223 are provided, with each second pressing part 222 corresponding to pressing two processing bodies. This arrangement can not only meet the processing requirements of mass production, but also achieve the pressing and fitting effect while meeting the load-bearing weight and space layout.

[0123] For blanking of finished parts, please refer to Figure 1 The automatic loading and unloading device 100 also includes a hopper 3 spaced apart from the loading device 1; a clamping structure 22 is movably mounted laterally and / or longitudinally. The clamping structure 22 can be moved to transfer finished parts to the hopper 3. The clamping structure 22 can adjust to the position of the hopper 3 and the loading device 1 while also allowing the loading device 1 to avoid rotation when the rotating shaft 230 rotates.

[0124] The present invention does not limit the form of dropping the finished parts into the silo 3. In one embodiment, a blowing structure 24 is provided on the second base 21, and the finished parts are blown into the silo 3 by the blowing structure 24. In other embodiments, a movable hopper can be provided, and the finished parts fall into the hopper by flipping the clamping structure 22, and are thereby introduced into the silo 3, and the material head moves to avoid the unloading device 2.

[0125] In this embodiment, the silo 3 is fixed to the second base 21. The side of the silo 3 facing the unloading device 2 is open, and multiple ventilation holes are provided on the surface of the silo 3. This reduces the weight of the silo 3 while ensuring air circulation within the silo 3. The clamping structure 22 includes a support base 221 and a second holding portion 222. A linear drive module is provided to drive the lateral displacement of the support base 221, and a damping limiter is provided to limit the lateral displacement range of the support base 221.

[0126] The specific working process is as follows:

[0127] Loading: The first cylinder 141 pushes the push-pull seat 142, driving the rocker arm 143, connected to the push-pull seat 142 by the second rotating shaft 20, to swing outward with the second rotating shaft 20 as the rotation center, until the upper portion of the elongated hole 1310 on the first driving end 131b is restrained on the second rotating shaft 20. The first holding end 131a swings to a released position with the first rotating shaft 10 as the rotation center. The elongated material is inserted through the discharge channel 1311 of the first holding end 131a and placed firmly in the feed channel 112 of the first base 11. The feed unit 12 is retrieved from the CNC machine tool magazine and installed on the spindle 220. The material pushing program is called up, and the feed unit 12 pushes the placed material flat, causing the end of the elongated material to protrude from the contoured groove 111 of the first base 11, forming a suspended processing body. The return of the first cylinder 141 drives the push-pull seat 142, pulling the rocker arm 143 to swing inward with the second rotating shaft 20 as the rotation center; until the lower part of the elongated hole 1310 on the first driving end 131b is limited on the second rotating shaft 20, and the first pressing end 131a swings from the release position to the pressing position, pressing the long material and starting processing.

[0128] Blanking: The support seat 221 moves along the X direction on the second base 21 with the cooperation of the cylinder and the guide rail until the matching platform 262 is stuck to the limit surface of the buffer. The cylinder rod of the second cylinder 223 is hinged to the tail end of the second holding rod, and the second driving end moves downward with the third rotating shaft 30 as the axis, raising the second holding end and the pressure head. The first base 11 rotates 180 degrees around the rotating shaft 230 with the semi-finished part that has not been blanked, so that the processing body falls steadily on the contour support block 23 in the mounting groove 221a. The second cylinder 223 moves upward, driving the second driving end to move upward with the third rotating shaft 30 as the axis; the second holding end is dropped, firmly pressing the semi-finished part against the contour support block 23, and the tool cuts the semi-finished part and the long material to complete the blanking. The third cylinder 251 pushes the slider 253, rotating the guide block 252. This in turn causes the support base 221, the second cylinder 223, and the second holding portion 222 to rotate 90°. After the support base 221 abuts against the limiting support rod 263, the blanking surface of the product is processed. After the finished part is processed, the third cylinder 251 rotates the support base 221 back to its original position.

[0129] Material collection: The second pressing rod 2221 remains in a compressed state, and the blowing structure 24 blows out air to clean the dirt on the contour support block 23. The matching platform 262 returns along the X-axis under the cooperation of the cylinder and the guide rail. The second pressing rod 2221 releases the finished parts, and the blowing structure 24 blows out air to blow the finished parts on the contour support block 23 into the hopper 3.

[0130] Start the next cycle of loading, blanking and collecting.

[0131] The present invention also proposes a product surface processing equipment, which includes A and an automatic loading and unloading device 100. The specific structure of the automatic loading and unloading device 100 refers to the above embodiment. Since this product surface processing equipment adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the product surface processing equipment also includes a CNC machine tool and a control device. The CNC machine tool includes a workbench 210 and a spindle 220 and a rotating shaft 230 that are movable relative to the workbench 210; the control device is electrically connected to the CNC machine tool and the automatic loading and unloading device 100. It should be noted that the control device can be a control system independent of the controller of the CNC machine tool, which can be electrically connected to the controller of the CNC machine tool and the cylinder in the automatic loading and unloading device 100. The control device can also be directly the controller of the CNC machine tool, which is electrically connected to the cylinder in the automatic loading and unloading device 100.

[0132] The control device can be an industrial computer. Specifically, the control device may include a processing device (such as a central processing unit (CPU) or a graphics processing unit (GPU)). This device can perform various appropriate actions and processes based on programs stored in read-only memory (ROM) or programs loaded from a storage device into random access memory (RAM). RAM also stores various programs and data required for the operation of the control device. The processing device, ROM, and RAM are interconnected via a bus. An input / output (I / O) interface is also connected to the bus. Typically, the following systems can be connected to the I / O interface: input devices such as a touchscreen, touchpad, keyboard, mouse, image sensor, microphone, accelerometer, gyroscope, etc.; output devices such as a liquid crystal display (LCD), speaker, vibrator, etc.; storage devices such as magnetic tape and hard disk; and communication devices. The communication devices can enable wireless or wired communication between the control device and other devices to exchange data. Although the figures illustrate a control device with various systems, it should be understood that implementation or inclusion of all the illustrated systems is not required. More or fewer systems may alternatively be implemented or included.

[0133] Based on this, the embodiment of the present application provides a control method for product surface processing equipment. Figure 10 This is a flow chart of the first embodiment of the control method of the surface processing equipment of the product of this application.

[0134] In this embodiment, the control method of the product surface processing equipment specifically includes the following steps:

[0135] Step S10, when parts of the plurality of elongated materials on the first base 11 protrude from the first base 11 to form a plurality of processed bodies;

[0136] It should be noted that multiple long materials are arranged side by side on the first base 11. The main shaft 220 is first connected to the feeding part 12, driving the feeding part 12 to push one end of the multiple long materials at the same time, thereby pushing the other end to move to protrude from the first base 11, thereby forming multiple processing bodies suspended on the first base 11. After the protruding length of the long material meets the requirements, the multiple first holding parts 13 press and fix the multiple long materials, and at the same time, the main shaft 220 switches the feeding part 12 on it to a tool.

[0137] The length of the long material suspended on the first base 11 should be greater than the length of the processing body, that is, a certain size needs to be reserved.

[0138] Step S20: Control the spindle 220 of the CNC machine tool to drive the tool to cut the multiple processing bodies, and control the rotation axis 230 of the CNC machine tool to rotate to perform the first stage of processing, thereby obtaining multiple semi-finished parts;

[0139] It should be noted that the first stage of processing corresponds to the five sides of the processing body. According to the different processing requirements of different sides and the multiple processing requirements of the same side, during the first stage of processing, there may be multiple tool replacement actions of the spindle 220 and forward and reverse rotation actions of the rotating shaft 230.

[0140] It should be noted that after completing the first stage of processing, the five sides of the processing body are processed, and the connection between the processing body and the long material is initially processed, that is, the diameter of the connection is reduced but not disconnected. On the one hand, it is convenient for the subsequent identification of the truncation position, and on the other hand, it can speed up the truncation process and reduce the difficulty of the truncation processing.

[0141] Step S30, after the first stage of processing is completed, the clamping structure 22 is controlled to clamp the plurality of semi-finished parts, and the first pressing portion 13 is maintained to press the plurality of elongated materials, and the spindle 220 of the CNC machine tool is controlled to drive the tool to cut off the ends of the plurality of semi-finished parts to form a plurality of blanking surfaces;

[0142] It should be noted that after the first stage of processing is completed, the processing body is maintained in a horizontal state and the support base 221 is in the first position. The spindle 220 switches the tool to the feed portion 12, pushing the multiple processing bodies from the open side of the installation slot 221a into the installation slot 221a. The second holding portion 222 and the contoured support block 23 cooperate to hold the multiple processing bodies. At this time, the elongated material is simultaneously held and fixed by the first holding portion 13 and the second holding portion 222. The connection between the processing body and the elongated material after the initial processing is exposed. The spindle 220 switches the feed portion 12 back to the tool, further processing the connection to completely sever the processing body, forming multiple blanking surfaces.

[0143] It should be noted that if the cutting tool is different from the machining tool for the blanking surface, the spindle 220 needs to switch the tool again.

[0144] Step S40: After controlling the clamping structure 22 to drive the multiple semi-finished parts to flip by a preset angle, the spindle 220 of the CNC machine tool is controlled to drive the tool to move and cut the multiple blanking surfaces to perform the second stage of processing, thereby obtaining multiple finished parts;

[0145] It should be noted that the preset angle can be 30°, 60°, 90°, etc. In this embodiment, the clamping structure 22 is controlled to flip 90° until the support seat 221 is against the multiple limit support rods 263. At this time, the processing body is converted from horizontal to vertical, with the blanking surface facing up, and the spindle 220 drives the tool to perform the second stage of processing.

[0146] If there are multiple processing requirements for the same side, the spindle 220 may need to replace the tool during the second stage of processing.

[0147] It should be noted that, during the entire second stage, the loading device 1 maintains the state in step S30, and the second pressing portion 222 always maintains the state of clamping the processing body.

[0148] In step S50 , after the second stage of processing is completed, the clamping structure 22 is controlled to move to correspond to the silo 3 , and the blanking structure is controlled to work so as to transfer the multiple finished parts into the silo 3 .

[0149] It should be noted that after the clamping structure 22 is controlled to move to correspond to the silo 3 , the second pressing portion 222 releases the finished parts, and the blanking structure works to transfer the multiple finished parts into the silo 3 .

[0150] When the blanking structure is the blowing structure 24 , the blowing structure 24 is controlled to blow air, so that a plurality of finished parts fall into the hopper 3 in a parabolic trajectory.

[0151] It should be noted that during this process, based on the current suspended size of the long material in the loading device 1, if the requirements are met, the spindle 220 switches to the corresponding tool to directly perform the first stage of processing; if the requirements are not met, the spindle 220 switches to the feeding part 12 to perform the material loading action.

[0152] It should be noted that, since the finished parts are light in weight and small in size, if the volume of the silo 3 is sufficient, the silo door of the CNC machine tool can be opened at the end of each shift to take materials from the silo 3.

[0153] In the technical solution of the present invention, the mechanical transmission principle is used as a carrier, and the clamping state of the material is automatically adjusted through the conversion of the loading device 1 and the unloading device 2, thereby improving production efficiency. The loading and unloading structure is stable, and components can be replaced in all directions to achieve the purpose of fast, efficient and mass production.

[0154] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's description and drawings, or direct / indirect applications in other related technical fields, within the scope of the present invention are included in the patent protection scope of the present invention.
