[0065] In related technologies, the mid-frame of smartwatches is typically manufactured using a cover plate to hold the product during the blanking process. However, currently, this is generally done manually by placing the product and manually operating the cover plate, involving several actions: placing the product, placing the cover plate, processing, removing the cover plate, and removing the product. In this process, the manual placement and removal of the cover plate is completely ineffective, wasting time, limiting production capacity, and easily causing defects such as damage to the product during material handling, thus reducing the product yield.

[0066] Based on the above concepts and problems, this invention proposes a clamping and positioning device 100. It is understood that the clamping and positioning device 100 is used for placing and positioning products to facilitate subsequent processing. The clamping and positioning device 100 is applied to a processing equipment 900, which can process products such as the mid-frame of a smartwatch, and is not limited thereto.

[0067] Please refer to the reference. Figures 1 to 8 As shown, in this embodiment of the invention, the pressing and positioning device 100 includes a body 1, a cover plate 2, a lifting assembly 3, and a flipping assembly 4. The body 1 is provided with a placement platform 11 for placing products. The cover plate 2 is movably connected to the body 1. The lifting assembly 3 is located on the side of the body 1 facing away from the placement platform 11. The lifting assembly 3 is provided with a push rod 31, one end of which passes through the placement platform 11. The flipping assembly 4 is located on the body 1 and spaced apart from the placement platform 11. The flipping assembly 4 is provided with a flipping space 43, in which part of the cover plate 2 is accommodated. The lifting assembly 3 drives the push rod 31 to push the cover plate 2 away from the placement platform 11, and the flipping assembly 4 drives the cover plate 2 to flip relative to the placement platform 11 to open or close the placement platform 11.

[0068] In this embodiment, the body 1 of the clamping and positioning device 100 is used to install, fix, and support components such as the cover plate 2, the lifting assembly 3, and the flipping assembly 4; that is, the body 1 provides an installation base for components such as the cover plate 2, the lifting assembly 3, and the flipping assembly 4. It is understood that the body 1 can be a frame, a machine base, a mounting frame, a mounting platform, or a mounting plane. The body 1 has a mounting surface, and a placement table 11 is provided on the mounting surface. Of course, the placement table 11 can be a placement fixture structure fixedly mounted on the mounting surface, or it can be a placement fixture structure detachably mounted on the mounting surface.

[0069] Understandably, in order to improve the versatility of the clamping and positioning device 100 and make it applicable to the positioning and processing of products of different sizes, the placement table 11 may optionally be connected to the mounting surface in a detachable manner, such as by snap-fit ​​connection, plug-in fit, screw connection or pin connection, etc., which is not limited here.

[0070] In this embodiment, in order to facilitate the installation of components such as cover plate 2, lifting assembly 3 and tilting assembly 4 on the machine body 1, and to enable the components such as cover plate 2, lifting assembly 3 and tilting assembly 4 to work together, the machine body 1 may be provided with a stepped structure or a gantry structure, etc., which is not limited here.

[0071] Understandably, the cover plate 2 is used to press or release the product on the placement platform 11, and the cover plate 2 is movably connected to the body 1. In this embodiment, the cover plate 2 and the body 1 can be connected by at least one of the following methods: rotational connection, sliding connection, or detachable connection, or a combination of multiple methods, which is not limited here. Optionally, the cover plate 2 is square. The shape and outline of the cover plate 2 are similar to the outer outline of the placement platform 11.

[0072] To prevent damage or crushing of the product when the cover plate 2 presses against it, in one embodiment, the placement platform 11 is provided with multiple support platforms 16 and multiple placement slots 17. The placement slots 17 are used to place and position the product. The multiple support platforms 16 are arranged around the multiple placement slots 17 and spaced apart at the periphery of the placement platform 11. The cover plate 2 is provided with a processing hole 24 corresponding to each placement slot 17. The side of the cover plate 2 facing the placement platform 11 is provided with a pressing boss 25 adjacent to the processing hole 24. When the cover plate 2 closes the placement platform 11, it is supported by the support platforms 16, and the pressing boss 25 presses against the product in the placement slot 17.

[0073] In this embodiment, as Figure 1 , Figure 2 and Figure 9 As shown, by setting a support platform 16 around the periphery of the placement platform 11, space is provided for the placement slot 17 for placing products on the placement platform 11. On the other hand, the support platform 16 supports the cover plate 2 while preventing the cover plate 2 from being damaged by excessive pressure.

[0074] Understandably, the support platform 16 can have structures such as protrusions, ribs, or ridges. Optionally, the support platform 16 and the placement platform 11 are integrally formed. In this embodiment, multiple support platforms 16 are disposed at the edge of the placement platform 11, and multiple placement grooves 17 are disposed on the inner side of the multiple support platforms 16. Optionally, the placement grooves 17 can be structures such as recesses or through grooves.

[0075] In this embodiment, the shape and outline of the placement groove 17 are similar to the shape and outline of the product. Optionally, the placement groove 17 is circular. To facilitate further processing of the product after the cover plate 2 has pressed it against the product, the cover plate 2 is provided with a processing hole 24 corresponding to each placement groove 17. It can be understood that the processing hole 24 and the placement groove 17 are configured in a one-to-one correspondence.

[0076] It should be noted that, to further prevent damage to the product when the cover plate 2 presses against it, a pressing boss 25 is provided on the side of the cover plate 2 facing the placement table 11 adjacent to the processing hole 24. The shape and outline of the pressing boss 25 are similar to the outer outline of the product. Understandably, the pressing boss 25 can be arranged around the processing hole 24. Of course, multiple pressing bosses 25 can also be provided, arranged around the processing hole 24. To ensure a balanced force when the cover plate 2 presses against the product, the multiple pressing bosses 25 are evenly distributed around the periphery of the processing hole 24. Optionally, the cover plate 2 has two pressing bosses 25 corresponding to each processing hole 24, and the two pressing bosses 25 are arranged symmetrically.

[0077] In order to avoid damage or displacement of the product when the cover plate 2 is opened, in this embodiment, a lifting component 3 is set up. The lifting component 3 first pushes the cover plate 2 in the opposite direction of the product pressing direction, so that the cover plate 2 is away from the product at a certain distance, and then the cover plate 2 is opened or reversed, thereby effectively avoiding damage or displacement of the product caused by the cover plate 2.

[0078] In this embodiment, the lifting assembly 3 is located on the side of the body 1 facing away from the placement platform 11. The lifting assembly 3 is provided with a push rod 31, one end of which passes through the placement platform 11. Of course, in other embodiments, the lifting assembly 3 can also be located on the mounting surface of the body 1 and adjacent to the placement platform 11. In this case, the periphery of the cover plate 2 can protrude from the placement platform 11, so that the push rod 31 corresponds to the periphery of the cover plate 2.

[0079] Understandably, the push rod 31 passes through the machine body 1, the placement platform 11, and the support platform 16 in sequence. In this embodiment, the placement platform 11 is provided with a push hole 12, which passes through the placement platform 11 and the machine body 1. At this time, the push rod 31 of the lifting assembly 3 is movably inserted through the push hole 12. When the push rod 31 needs to push the cover plate 2, the lifting assembly 3 drives the push rod 31 to move, so that the push rod 31 extends out of the push hole 12 and pushes the cover plate 2 away from the support platform 16. When the cover plate 2 is opened, or when the cover plate 2 is closed again, the push rod 31 retracts into the push hole 12 to facilitate the effect of the cover plate 2 pressing the product.

[0080] In this embodiment, to facilitate the automatic opening or closing of the cover plate 2, the clamping and positioning device 100 is also provided with a flipping component 4. By using the flipping component 4 to drive the cover plate 2 to flip relative to the placement platform 11, the placement platform 11 can be opened or closed. It is understood that the flipping component 4 can be a structure that drives the cover plate 2 to flip, such as a flipping motor, a flipping cylinder, a flipping robot, etc., and is not limited here.

[0081] The clamping and positioning device 100 of the present invention uses a placement platform 11 on the machine body 1 to place the product to be processed, and a cover plate 2 is movably connected to the machine body 1 to clamp or release the product on the placement platform 11, thereby facilitating subsequent processing and improving processing accuracy. Simultaneously, by providing a lifting assembly 3 and a tilting assembly 4, the lifting assembly 3 is located on the side of the machine body 1 facing away from the placement platform 11, and a push rod 31 is provided on the lifting assembly 3, with one end of the push rod 31 penetrating the placement platform 11. The tilting assembly 4 is located on the machine body. 1. A flipping space 43 is provided in the flipping component 4, so that part of the cover plate 2 is accommodated in the flipping space 43. In this way, the lifting component 3 can drive the top rod 31 to push the cover plate 2 away from the placement table 11, thereby releasing the pressed product in the positive vertical direction, avoiding secondary damage to the product during the opening of the cover plate 2 and causing problems such as product displacement. Furthermore, the flipping component 4 drives the cover plate 2 to flip relative to the placement table 11, so as to realize the operation of opening or closing the cover plate 2 on the placement table 11, thereby facilitating the picking and placing of products on the placement table 11. The pressing and positioning device 100 of the present invention not only has a relatively simple structure, but also realizes automatic flipping, effectively improving the processing efficiency of the product, while avoiding the three-way damage problem of the product, and can adapt to the processing of various products, with wide versatility.

[0082] In one embodiment, the placement platform 11 is provided with a push hole 12, which penetrates the placement platform 11 and the body 1. The lifting assembly 3 includes a lifting drive 32 and a push plate 33. The lifting drive 32 is located on the side of the body 1 facing away from the placement platform 11. The push plate 33 is connected to the output end of the lifting drive 32. The push plate 33 is provided with a push rod 31, and the end of the push rod 31 away from the push plate 33 is movably inserted through the push hole 12. The lifting drive 32 drives the push plate 33 to move closer to or away from the body 1 so that the push rod 31 pushes the cover plate 2 away from the placement platform 11.

[0083] In this embodiment, as Figures 1 to 4 As shown, by placing the lifting drive 32 of the lifting assembly 3 on the side of the machine body 1 facing away from the placement platform 11, and connecting the push plate 33 to the output end of the lifting drive 32, the push plate 33 is located on the side of the machine body 1 facing away from the placement platform 11. It is understandable that this arrangement allows for efficient use of space, while the lifting drive 32 drives the push plate 33 to move closer to or away from the machine body 1, providing driving force to the push rod 31, causing the push rod 31 to push the cover plate 2 away from the placement platform 11.

[0084] Understandably, the lifting drive component 32 provides driving force to the push plate 33 and the push rod 31. The lifting drive component 32 can be a lifting motor, a lifting cylinder, or a drive module, etc., and is not limited here. In this embodiment, the push plate 33 is provided to transfer the driving force of the lifting drive component 32 to the push rod 31, and can also be used to transmit the driving force of the lifting drive component 32 to multiple push rods 31 simultaneously, so as to achieve balanced force on the cover plate 2.

[0085] In this embodiment, the push rod 31 can be rod-shaped, column-shaped, bar-shaped, or strip-shaped. One end of the push rod 31 is connected to the push plate 33, and the other end of the push rod 31 is movably inserted into the push hole 12. When it is necessary to push the cover plate 2, the lifting drive 32 drives the push plate 33 closer to the machine body 1, so that the push rod 31 pushes the cover plate 2 away from the placement platform 11. When the cover plate 2 is flipped by the flipping assembly 4 to open the placement platform 11, the lifting drive 32 drives the push plate 33 away from the machine body 1, so that the push rod 31 retracts into the push hole 12, that is, the lifting assembly 3 resets, so as to avoid the push rod 31 interfering with the cover plate 2 pressing and closing the product when the flipping assembly 4 drives the cover plate 2 to flip and close the placement platform 11, resulting in the inability to close the product.

[0086] Of course, in order to avoid damaging the product when the flipping component 4 flips the cover plate 2 to close the placement table 11, when the cover plate 2 is flipped by the flipping component 4 to open the placement table 11, the push rod 31 may not retract into the push hole 12. When the flipping component 4 flips the cover plate 2 to close the placement table 11, the push rod 31 supports the cover plate 2, and then the lifting drive component 32 drives the push plate 33 to retract the push rod 31 into the push hole 12, so that the cover plate 2 is slowly pressed against the product surface. This is not limited here.

[0087] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the push plate 33 is provided with multiple push rods 31, which are distributed at intervals around the periphery of the placement platform 11. The placement platform 11 is provided with a push hole 12 corresponding to each push rod 31.

[0088] Understandably, by setting multiple push rods 31, which are distributed around the periphery of the placement platform 11, the periphery of the cover plate 2 can be balanced when it is pushed. In this embodiment, multiple support platforms 16 of the placement platform 11 are correspondingly arranged with multiple push rods 31, that is, each push hole 12 passes through a support platform 16, and a push rod 31 is movably inserted into the push hole 12 of a support platform 16.

[0089] In one embodiment, such as Figures 1 to 4 , Figure 7As shown, the lifting drive component 32 includes multiple components, which are spaced apart. The push plate 33 has a connecting part 331 corresponding to each lifting drive component 32, and the connecting part 331 is connected to the output end of the lifting drive component 32. It can be understood that by setting multiple lifting drive components 32, the driving force on the multiple push rods 31 is increased, while ensuring the stability and balance of the pushing force. This ensures that the cover plate 2 is lifted simultaneously by the multiple push rods 31, thus effectively improving the protection of the product and preventing damage to the cover plate 2 or product displacement.

[0090] In one embodiment, the flipping assembly 4 includes a flipping drive 41 and a flipping arm 42. The flipping drive 41 is disposed on the body 1 and spaced apart from the placement platform 11. The flipping arm 42 is connected to the output end of the flipping drive 41. A flipping space 43 is provided at the end of the flipping arm 42 away from the flipping drive 41. The flipping drive 41 drives the flipping arm 42 to flip, and the flipping space 43 drives the cover plate 2 to flip relative to the placement platform 11 to open or close the placement platform 11.

[0091] In this embodiment, as Figures 1 to 4 As shown, by configuring the flipping assembly 4 as a flipping drive 41 and a flipping arm 42, the flipping drive 41 provides driving force to the flipping arm 42, so that the flipping arm 42 drives the cover plate 2 to flip. It is understood that the flipping drive 41 can be a rotary motor or a rotary cylinder or other structure that can enable the flipping arm 42 to drive the cover plate 2 to flip, and is not limited here.

[0092] To ensure that the cover plate 2 is flipped open and then flipped to close the placement platform 11, the cover plate 2 and the placement platform 11 are positioned correctly, i.e., precisely positioned. One side of the cover plate 2 is rotatably connected to the body 1. The flipping space 43 of the flipping arm 42 is connected to the adjacent side of the cover plate 2, so that the flipping drive 41 drives the flipping arm 42 to flip, and the flipping space 43 causes the cover plate 2 to flip relative to the placement platform 11 around the rotatable connection point, so as to open or close the placement platform 11. It is understood that the flipping arm 42 can be rod-shaped, strip-shaped, etc. In order to make the cover plate 2 flip smoothly, the flipping arm 42 is set in a right-angle Z-shape, which is not limited here.

[0093] In one embodiment, such as Figures 1 to 4 As shown, the end of the tilting arm 42 away from the tilting drive component 41 is provided with a connecting block 44. Two protruding posts 45 protrude from the side of the connecting block 44 facing away from the tilting arm 42. The two protruding posts 45 are spaced apart so that they cooperate with the connecting block 44 to form a tilting space 43. This arrangement facilitates the placement of the side of the cover plate 2 within the tilting space 43 and also allows for easy replacement of the cover plate 2. Optionally, the protruding posts 45 can be circular, square, or other similar structures; no limitation is made here.

[0094] In one embodiment, the body 1 is further provided with a connecting platform 13 adjacent to the placement platform 11. The connecting platform 13 is provided with a sliding hole 131. The cover plate 2 is slidably inserted into the sliding hole 131 through the rotating shaft 21 and is rotatably connected to the connecting platform 13. The extension direction of the sliding hole 131 is consistent with the movement direction of the push rod 31. When the lifting component 3 drives the push rod 31 to push the cover plate 2, the cover plate 2 drives the rotating shaft 21 to move along the sliding hole 131. When the flipping drive component 41 drives the flipping arm 42 to flip, the flipping space 43 drives the cover plate 2 to flip around the connecting platform 13 to open or close the placement platform 11.

[0095] In this embodiment, as Figures 1 to 4 As shown, by setting a connecting platform 13 and providing a sliding hole 131 in the connecting platform 13, the extension direction of the sliding hole 131 is consistent with the movement direction of the push rod 31. This allows the connecting platform 13 to achieve a rotatable connection with the cover plate 2 through the hole-shaft mating structure of the sliding hole 131 and the rotating shaft 21. The sliding hole 131 is set in the form of a strip hole or an oblong hole. It also allows the cover plate 2 to drive the rotating shaft 21 to move along the sliding hole 131 under the push of the push rod 31, thereby achieving the functions of movement guidance and positioning.

[0096] Optionally, the extension length of the sliding hole 131 is greater than or equal to the moving distance of the push rod 31 pushing the cover plate 2. This ensures that the push rod 31 pushes the cover plate 2 away from the placement table 11 and the product, so that the product can be completely detached from the cover plate 2. Thus, when the flip arm 42 drives the cover plate 2 to flip open, the product is effectively protected and protected from damage or displacement.

[0097] In one embodiment, the distance between the two protrusions 45 is greater than or equal to the moving distance of the push rod 31 pushing the cover plate 2. It can be understood that this arrangement effectively ensures that the push rod 31 pushes the cover plate 2 away from the placement table 11 and the product, so that the product can be completely detached from the cover plate 2. Thus, when the flipping arm 42 drives the cover plate 2 to flip open, the product is effectively protected and damaged or displaced.

[0098] In this embodiment, as Figure 3 and Figure 4As shown, two protrusions 45 are located on opposite sides of the cover plate 2. When the cover plate 2 closes the placement platform 11, the protrusions 45 between the cover plate 2 and the placement platform 11 are located within the clearance space where the support platform 16 supports the cover plate 2. When the cover plate 2 is pushed off the product by the push rod 31, the cover plate 2 abuts or approaches the protrusions 45 on the side of the cover plate 2 facing away from the placement platform 11. At this time, when the control flipping drive 41 drives the flipping arm 42 to flip, the flipping arm 42 folds and moves until the protrusions 45 between the cover plate 2 and the placement platform 11 abut against the cover plate 2. Then, the flipping drive 41 drives the flipping arm 42 to continue flipping, causing the protrusions 45 to fold the cover plate 2 to open the placement platform 11. When it is necessary to close the cover plate 2, the flipping drive 41 drives the flipping arm 42 to flip in the opposite direction, causing the protrusions 45 to flip the cover plate 2 towards the placement platform 11 to close.

[0099] Understandably, when the cover plate 2 closes the placement platform 11, the protruding post 45 on the side of the cover plate 2 facing away from the placement platform 11 can press against the cover plate 2 to clamp the product. Of course, the protruding post 45 can also simply serve the purpose of driving the cover plate 2 to flip over, which is not limited here. Optionally, the distance between the two protruding posts 45 is greater than the thickness of the cover plate 2.

[0100] To further ensure that the cover plate 2 can accurately press the product after it covers the placement platform 11, in one embodiment, one of the placement platform 11 and the cover plate 2 is provided with a positioning protrusion 14, and the other is provided with a positioning hole 22; when the cover plate 2 covers the placement platform 11, the positioning protrusion 14 is positioned and accommodated in the positioning hole 22.

[0101] In this embodiment, as Figures 1 to 4 As shown, by providing positioning protrusions 14 and positioning holes 22 on the placement platform 11 and the cover plate 2 respectively, the positioning protrusions 14 are positioned and accommodated in the positioning holes 22 when the cover plate 2 closes the placement platform 11, so as to achieve positioning of the cover plate 2.

[0102] It is understandable that the positioning protrusion 14 can be a protruding post, protruding strip, positioning pin, positioning needle, or other structure, and is not limited here. The positioning protrusion 14 can be set on the placement platform 11 or on the cover plate 2, and the positioning hole 22 can be set on the cover plate 2 or on the placement platform 11. The number of positioning protrusions 14 is the same as the number of positioning holes 22. Optionally, multiple positioning protrusions 14 and positioning holes 22 can be provided, and is not limited here.

[0103] To ensure that the positioning protrusion 14 is positioned and accommodated within the positioning hole 22 when the cover plate 2 closes the placement platform 11, the end of the positioning protrusion 14 is tapered or pointed to facilitate guidance.

[0104] In one embodiment, to ensure that the cover plate 2 presses the product firmly during processing, such as Figures 1 to 4As shown, the clamping and positioning device 100 also includes a locking assembly 5, which includes a locking drive 51 and a locking pressure head 52. The locking drive 51 is located on the machine body 1, and the locking pressure head 52 is connected to the output shaft of the locking drive 51. The locking pressure head 52 is provided with a clamping surface 53. When the cover plate 2 closes the placement platform 11, the locking drive 51 drives the locking pressure head 52 to rotate so that the clamping surface 53 locks or releases the cover plate 2.

[0105] In this embodiment, the locking assembly 5 is used to lock the cover plate 2 onto the placement table 11 to securely press the product and prevent displacement during processing. By configuring the locking assembly 5 as a locking drive 51 and a locking pressure head 52 structure, automatic locking or releasing of the cover plate 2 is achieved, improving convenience. It is understood that the locking drive 51 can be a rotary motor, rotary electric motor, or other structure capable of driving the locking pressure head 52 to rotate, thereby locking or releasing the cover plate 2 on the pressing surface 53; this is not limited here. Optionally, the locking pressure head 52 can be an L-shaped, T-shaped, or other structure; this is not limited here.

[0106] It should be noted that the locking head 52 of the locking assembly 5 can be located at the periphery of the placement table 11 or at the center of the placement table, and there is no limitation on this. In this embodiment, the locking drive 51 is located on the side of the body 1 facing away from the placement table 11, and the output shaft of the locking drive 51 passes through the body 1 / body 1 and the placement table 11 and is connected to the locking head 52.

[0107] Understandably, after the flipping drive 41 drives the flipping arm 42 to flip, causing the protruding post 45 to flip and close the cover plate 2 towards the placement table 11, the protruding post 45 can continue to press the cover plate 2 to the preset pressing position. At this time, the locking drive 51 drives the locking head 52 to rotate, so that the pressing surface 53 locks or releases the cover plate 2.

[0108] Optionally, the locking assembly 5 includes a plurality of locking drive members 51 and a plurality of locking pressure heads 52. Some of the locking drive members 51 and some of the locking pressure heads 52 are disposed around the periphery of the placement platform 11 to provide a uniform and stable pressing force on the periphery of the cover plate 2. Of course, at least one locking drive member 51 and one locking pressure head 52 may also be provided to cooperate, such that the locking pressure head 52 is located within the placement platform 11.

[0109] In one embodiment, such as Figures 1 to 4As shown, the locking assembly 5 includes multiple locking drive members 51 and multiple locking pressure heads 52. At least one locking drive member 51 is located on the side of the machine body 1 facing away from the placement platform 11, and the placement platform 11 has a locking hole 15 corresponding to the locking drive member 51. The output shaft of the locking drive member 51 is movably inserted through the locking hole 15 and connected to a locking pressure head 52. The cover plate 2 also has a clearance hole 23 corresponding to the locking pressure head 52. When the cover plate 2 closes the placement platform 11, the locking pressure head 52 passes through the clearance hole 23 and is located on the side of the cover plate 2 facing away from the placement platform 11. The locking drive member 51 drives the locking pressure head 52 to rotate so that the pressing surface 53 locks or releases the cover plate 2. When the pressing surface 53 releases the cover plate 2, the lifting assembly 3 drives the top rod 31 to push the cover plate 2 so that the cover plate 2 moves away from the placement platform 11, and the locking pressure head 52 is accommodated or disengaged from the clearance hole 23.

[0110] In this embodiment, the clearance hole 23 of the cover plate 2 serves two purposes: firstly, it allows the locking head 52 to be positioned so that when the cover plate 2 is flipped to open the placement platform 11, the locking head 52 does not affect the flipping of the cover plate 2; secondly, it allows the locking head 52 to pass through the clearance hole 23 and press against the outer surface of the cover plate 2. That is, when the cover plate 2 closes the placement platform 11, the locking head 52 passes through the clearance hole 23. At this time, the locking drive member 51 drives the locking head 52 to rotate so that the pressing surface 53 locks or releases the cover plate 2, thereby ensuring that a uniform pressing force is provided to the cover plate 2 and avoiding insufficient force on the middle part of the cover plate 2.

[0111] In one embodiment, the pressing and positioning device 100 further includes a transfer mechanism 6, which includes a transfer table 61 and a positioning component 62. The transfer table 61 is connected to the machine body 1 and located on one side of the placement table 11. The transfer table 61 is provided with a transfer groove 611 and is used to place the turnover tray 7. The positioning component 62 is provided on the transfer table 61 and is used to position the turnover tray 7.

[0112] In this embodiment, as Figure 1 , Figure 5 , Figure 6 and Figure 9As shown, a transfer mechanism 6 is set up to place the turntable 7. It is understood that the turntable 7 is used to hold products to be processed or products that have already been processed, thus facilitating product transfer. Initially, the turntable 7 holds multiple products to be processed. After the turntable 7 is positioned on the transfer table 61 by the positioning component 62, the products to be processed on the turntable 7 are transferred to the placement slot 17 of the placement table 11 by a robotic arm or transfer mechanism (e.g., a transfer module or transfer clamping component). Then, the flipping component 4 drives the cover plate 2 to flip and close the placement table 11, and the locking component 5 locks the cover plate 2 to facilitate the processing of the products. After processing is completed, the cover plate 2 is released by the locking assembly 5. Then, the push rod 31 pushes the cover plate 2 away from the product. The flipping assembly 4 then drives the cover plate 2 to open the placement table 11. The processed product in the placement slot 17 is then transferred to the turnover tray 7 by a robot or transfer mechanism (such as a transfer module or transfer clamping assembly). It is understood that each transfer can be one, multiple, or all of them, and no limitation is made here.

[0113] Understandably, positioning the turntable 7 on the transfer table 61 by using the positioning component 62 can avoid problems such as displacement or inaccuracy when the transfer mechanism transfers products.

[0114] In one embodiment, such as Figures 1 to 6 , Figure 8 As shown, the positioning component 62 includes a positioning boss 621 and a positioning groove 622. The positioning boss 621 is located on one of the periphery of the turntable 7 and the side wall of the flow groove 611, and the positioning groove 622 is located on the other of the periphery of the turntable 7 and the side wall of the flow groove 611.

[0115] In this embodiment, by setting a positioning boss 621 and a positioning groove 622 on the periphery of the turntable 7 and the side wall of the transfer groove 611 respectively, the positioning of the turntable 7 is achieved by utilizing the positioning cooperation of the positioning boss 621 and the positioning groove 622.

[0116] In one embodiment, the positioning component 62 includes a positioning drive 623, which is located on the side of the turntable 61 away from the positioning boss 621 or the positioning groove 622. The output end of the positioning drive 623 is also provided with a positioning protrusion 624, and the turntable 7 is provided with a positioning push-pull hole 71. When the turntable 7 is placed in the turntable 611, the positioning protrusion 624 is movably inserted into the positioning push-pull hole 71, and the positioning drive 623 drives the positioning protrusion 624 to move the turntable 7 in the turntable 611, so that the positioning boss 621 inserts into or exits the positioning groove 622.

[0117] In this embodiment, as Figure 5 and Figure 6 , Figure 8As shown, by further configuring the positioning drive member 623 and providing a positioning protrusion 624 at the output end of the positioning drive member 623, and providing a positioning push-pull hole 71 on the turntable 7, the positioning drive member 623 can drive the positioning protrusion 624 to move the turntable 7 within the flow groove 611, so that the positioning protrusion 621 can be inserted into or removed from the positioning groove 622, thereby achieving positioning of the turntable 7 in two directions, that is, positioning in the direction in which the positioning drive member 623 drives the turntable 7 (e.g., the Y direction) and in the direction perpendicular to the driving direction of the positioning drive member 623 (e.g., the Z direction).

[0118] Understandably, in order to further achieve positioning and guidance of the rotating disk 7 driven by the positioning drive 623, the bottom wall of the circulation groove 611 of the turntable 61 is provided with a guide groove. A connecting arm is connected to the output shaft of the positioning drive 623. The connecting arm is slidably accommodated in the guide groove, and a positioning protrusion 624 is protruding on the connecting arm. When the rotating disk 7 is placed in the circulation groove 611, the bottom wall of the rotating disk 7 abuts against the bottom wall of the circulation groove 611, and the positioning protrusion 624 passes through the positioning push-pull hole 71. At this time, the rotating disk 7 and the guide groove of the cover are aligned to form a guide channel.

[0119] In this embodiment, the diameter or area of ​​the positioning push-pull hole 71 is greater than or equal to the cross-sectional area of ​​the positioning protrusion 624. Optionally, the hole shape of the positioning push-pull hole 71 matches the outer contour of the positioning protrusion 624.

[0120] In one embodiment, the sidewall of the transfer groove 611 is further provided with a guide slope 612. The guide slope 612 is disposed adjacent to the positioning boss 621 or the positioning groove 622 and is located on the side of the direction in which the positioning boss 624 drives the turnover disk 7 to move in the transfer groove 611. When the positioning drive member 623 drives the positioning boss 624 to move the turnover disk 7 in the transfer groove 611, the guide slope 612 guides the turnover disk 7 so that the positioning boss 621 is inserted into the positioning groove 622.

[0121] In this embodiment, as Figure 1 and Figure 5 As shown, by providing a guide slope 612 on the side wall of the transfer groove 611, when the positioning drive member 623 drives the positioning protrusion 624 to move the turnover disk 7 within the transfer groove 611, the guide slope 612 guides the turnover disk 7 so that the positioning protrusion 621 inserts into the positioning groove 622. Thus, the guide slope 612 is used to position the turnover disk 7 simultaneously in a direction perpendicular to the direction driven by the positioning drive member 623 (e.g., the Y direction) and in a direction perpendicular to the driving direction of the positioning drive member 623 (e.g., the Z direction), further improving the positioning and locking of the turnover disk 7.

[0122] Understandably, the side of the transfer table 61 facing the positioning drive member 623 is provided with a positioning groove 622, and the groove opening of the positioning groove 622 faces the positioning drive member 623; or, a through groove structure is provided on the side of the transfer table 61 facing the positioning drive member 623, and a limiting block is provided on the transfer table 61 so that the limiting block covers the through groove structure to form the positioning groove 622. In this way, when the positioning drive member 623 drives the positioning protrusion 624 to move the turnover disk 7 in the transfer groove 611, so that when the positioning protrusion 621 is inserted into the positioning groove 622, the turnover disk 7 is limited and abutted against the limiting block.

[0123] In this embodiment, the replacement process of the turnover tray 7 is as follows: after all the products (materials) in the turnover tray 7 have been processed, the positioning drive 623 drives the positioning protrusion 624 to move backward, pulling the turnover tray 7 out along the Y direction. At this time, the positioning protrusion 621 and the positioning protrusion 624 of the turnover tray 7 release the Z-direction limit of the turnover tray 7, and the entire turnover tray 7 can be taken out directly, and then a tray of unprocessed products can be placed in.

[0124] Understandably, after the turnover tray 7 is newly placed in, the positioning drive component 623 drives the positioning protrusion 624 to move forward, pushing the turnover tray 7 in the Y direction. During the movement of the turnover tray 7, it will be guided by the guide slope 612 of the turnover table 61 for positioning in the X direction. At the same time, the thrust of the positioning drive component 623 pushes the turnover tray 7 to the positioning protrusion 621, which is inserted into the positioning groove 622 and clamped. At this point, the turnover tray 7 is completely fixed in the X, Y, and Z directions, completing the secondary positioning process of the turnover tray 7.

[0125] In this embodiment, the clamping and positioning device 100 or the processing equipment 900 is equipped with a material handling device, which is used to transfer materials between the turnover tray 7 and the clamping and positioning device 100. The material handling device can be a robotic arm, a transfer module, or other structures, and is not limited here. The turnover tray 7 is used to store processed / unprocessed products, which can be easily replaced modularly after processing. The ejection assembly 3 is used to eject the cover plate 2 a certain distance, so that the cover plate 2 is separated from the product to prevent damage. The flipping assembly 4 drives the cover plate 2 to rotate a certain angle. The placement table 11 is used for positioning and supporting the product during processing.

[0126] It should be noted that the clamping and positioning device 100 of the present invention uses an automated in-machine pick-and-place technology for the product holding solution with cover plate 2. The clamping and positioning device 100 of the present invention comprises four parts: a cover plate 2 rotating device, a cover plate 2 ejection device, and a turnover tray 7 device. The entire device has a relatively simple structure, can adapt to the processing of various products, and has wide versatility. Compared with the existing manual pick-and-place cover plate solution, it greatly improves the product processing efficiency.

[0127] Understandably, the clamping and positioning device 100 does not require manual intervention. The cover plate is automatically ejected and rotated through the rotation and ejection devices. Products are automatically picked up and placed without manual intervention. The use of the internal turntable 7 saves equipment door opening and closing time and waiting time, realizing automated processing inside the machine. The turntable 7 has added a secondary positioning device to meet the accuracy requirements for picking up and placing products inside the machine.

[0128] This invention achieves automatic rotation of the cover plate 2 by using a rotating cover plate 2 and an ejection device, saving manual handling of the cover plate 2 and reducing the time required for handling the cover plate 2, thus improving processing efficiency. Simultaneously, the automatic rotation of the cover plate 2, in conjunction with the material handling device and the turntable 7, enables automated in-machine processing of the product, improving efficiency and avoiding the three-way damage problem of the product. This overcomes the difficulty of achieving automated in-machine material handling using cover plate holding solutions in the machining field. Furthermore, the secondary positioning function of the turntable 7 eliminates the need for high precision when employees or robotic arms place the tray, minimizing the difficulty of subsequent AGV automated tray handling and providing a foundation for future unmanned workshops.

[0129] Understandably, the process of ejecting cover plate 2 is as follows: Figure 3 As shown, during processing, the cover plate 2 is in a state of pressing the product. After the product processing is completed, the locking head 52 is released and rotated 90 degrees. At this time, the lifting drive component 32 will slowly extend, pushing the push plate 33 and the push rod 31 upward. When the cover plate 2 contacts the push rod 31, it will be slowly lifted up under the action of the push rod 31, separating from the product. Figure 4 As shown; this ejection process is mainly to avoid affecting the product's positioning accuracy and causing three types of damage to the product when the cover plate 2 rotates.

[0130] Cover plate rotation process: After cover plate 2 is pushed out by push rod 31, cover plate 2 rotates under the drive of flipping drive component 41, as follows: Figures 4 to 1 , Figure 2 The process is shown.

[0131] Material handling process: After the cover plate 2 has rotated, the material handling device performs the action of clamping the product under the drive of the machine tool spindle, that is, the processed product is taken back from the placement table 11 to the turnover tray 7, and the unprocessed product is clamped from the turnover tray 7 and placed on the placement table 11.

[0132] After the feeding process is completed, the cover plate 2 rotates in the opposite direction under the drive of the tilting drive component 41, that is, from Figure 1 , Figure 2 Status Figure 4 In the current state, the lifting drive component 32 drives the push rod 31 to retract, and the cover plate 2 moves downward, i.e., from Figure 4 Status Figure 3In the state where it comes into contact with the product, the locking head 52 rotates 90 degrees to press the cover plate 2 tightly, and the product is processed.

[0133] like Figure 9 As shown, the present invention also proposes a processing device 900, which includes a main body 800 and the aforementioned clamping and positioning device 100, the clamping and positioning device 100 being connected to the main body 800. The specific structure of the clamping and positioning device 100 is as described in the foregoing embodiments. Since this processing device adopts all the technical solutions of all the foregoing embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be elaborated upon here.

[0134] Understandably, the main body 800 of the processing equipment 900 may be equipped with a frame or base, or with a material handling device, and also includes a control structure. The control structure is electrically connected to the lifting component 3, the flipping component 4, the locking component 5 of the clamping and positioning device 100, and the positioning drive component 623 of the transfer mechanism 6, so as to control the working status of the lifting component 3, the flipping component 4, the locking component 5, and the positioning drive component 623 of the transfer mechanism 6.

[0135] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
