[0040] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0041] It should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0042] It should be noted that the first direction in this application is... Figure 1 The X direction (i.e., the length direction of the base plate) is the second direction. Figure 2 The Z-direction (i.e., the height direction of the base plate).

[0043] like Figure 1As shown, an embodiment of this utility model provides a limiting component 12 for transferring a PCB board 10, including a material transfer drive component 11, a limiting component 12, a support frame 13, and a material support mechanism 14; the limiting component 12 is installed on the support frame 13 and is used to limit one end of the PCB board 10; the material transfer drive component 11 is connected to the support frame 13 and is used to drive the support frame 13 to move along a first direction; it can be understood that the material transfer drive component 11 includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc.

[0044] The material support mechanism 14 includes a material support drive component 141 and a material support assembly 142 slidably mounted on the support frame 13. The material support drive component 141 is mounted on the support frame 13 and connected to the material support assembly 142. The material support drive component 141 drives the material support assembly 142 to move along a first direction, so that the material support assembly 142 can support the other end of the PCB board 10. It can be understood that the material support assembly 142 can be slidably mounted on the support frame 13 along the first direction via a guide rail slider assembly. The material support drive component 141 includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc.

[0045] Specifically, when the PCB board 10 moves along the first direction onto the transfer mechanism 1, the limiting component 12 limits one end of the PCB board 10, and the material-supporting component 142 supports the other end of the PCB board 10. The transfer drive unit drives the support frame 13 to move along the first direction, and the limiting component 12 pushes the PCB board 10 along the first direction. The material-supporting component 142 always supports the end of the PCB board 10 away from the limiting component 12, thereby ensuring the stability of the transfer mechanism 1 in transferring the PCB board 10. When the PCB board 10 is delivered directly above the processing table 4, after the limiting component 12 disengages from the PCB board 10, the material-supporting drive unit 141 drives the material-supporting component 142 to move along the first direction until the material-supporting component 142 disengages from the PCB board 10. The PCB board 10 then falls onto the processing table 4, thus completing the automatic loading function of the processing table 4.

[0046] In this utility model, the material support drive 141 can drive the material support assembly 142 to move along the first direction, thereby adjusting the distance between the material support assembly 142 and the limiting assembly 12. Thus, the material transfer mechanism 1 can transfer PCB boards 10 of different lengths, improving the applicability, versatility and flexibility of the material transfer mechanism 1. Furthermore, the adjustment operation of the material transfer mechanism 1 is simple.

[0047] In one embodiment, such as Figure 1 and Figure 2As shown, the material transfer mechanism 1 further includes a guide member 1427 mounted on the material support assembly 12 and a guide bracket 15 mounted on the support frame 13. The guide bracket 15 is provided with a guide groove 151. The material support drive member 141 is also used to drive the support mechanism 2 to move in a first direction. The guide member 1427 moves along the guide groove 151 so that the claw hook 1422 disengages from the PCB board 10. Understandably, the guide groove 151 extends forward and upward. Understandably, the guide member 1427 includes, but is not limited to, guide wheels, guide posts, etc.; the guide groove 151 extends forward and upward.

[0048] Specifically, after the material transfer mechanism 1 transports the PCB board 10 to the top of the processing table 4, the material support drive 141 drives the material support plate 1424 to move along the first direction, and the guide 1427 moves along the guide groove 151. The guide 1427 moving along the guide groove 151 will drive the material support plate 1424 to move forward and upward, so that the material support assembly 142 can be separated from the PCB board 10, ensuring the stability of the claw hook 1422 separating from the PCB board 10.

[0049] In one embodiment, such as Figure 1 and Figure 2 As shown, the material support assembly 142 includes a first elastic element 1421, a claw hook 1422, a support column 1423, and a material support plate 1424 with a through hole 14241. One end of the support column 1423 is connected to the claw hook 1422, and the other end of the support column 1423 slides through the through hole 14241 and is connected to the guide element 1427. A material support space 1425 for supporting the PCB board 10 is formed between the claw hook 1422, the material support plate 1424, and the support column 1423. The opposite ends of the first elastic element 1421 are respectively connected to the material support plate 1424 and the claw hook 1422. It can be understood that the first elastic element 1421 includes, but is not limited to, a spring, etc., and the claw hook 1422 is slidably mounted below the material support plate 1424 via the support column 1423.

[0050] The material support plate 1424 is slidably mounted on the support frame 13, and the material drive component 141 is connected to the material support plate 1424.

[0051] The material support drive 14 is also used to drive the material support assembly 142 to move along the first direction, so that the guide 1427 can move along the guide groove 151, thereby driving the support column 1423 to move in the through hole 14241, so that the claw hook 1422 disengages and avoids the PCB board 10.

[0052] In this embodiment, the claw hook 1422 is slidably mounted below the material support plate 1424 via the support column 1423. The first elastic member 1421 is installed between the material support plate 1424 and the claw hook 1422, thereby ensuring a flexible contact between the claw hook 1422 and the PCB board 10. This avoids hard contact between the material support assembly 142 and the PCB board 10, preventing scratches on the PCB board 10 and ensuring the quality of the PCB board 10. Furthermore, the elastic force of the first elastic member 1421 allows the claw hook 1422 to firmly support the bottom of the PCB board 10, i.e., clamping the PCB board 10 within the material support space 1425, further ensuring the stability of the material support assembly 142 when it exits the PCB board 10. Furthermore, as the guide member 1427 moves in the guide groove 151, the claw hook 1422 moves upward on the material support plate 1424 via the support column 1423, so that the claw hook 1422 can gradually detach from the material to be transferred 10, ensuring the stability of the claw hook 1422 detaching from the material to be transferred 10.

[0053] In one embodiment, such as Figure 1 As shown, the material support assembly 142 further includes a material support sensor 1426 mounted on the material support plate 1424. The material support sensor 1426 is used to detect whether a PCB board 10 is supported in the material support space 1425. It can be understood that the material support sensor 1426 includes, but is not limited to, laser sensors, photoelectric sensors, etc.; the material support sensor 1426 can detect in real time whether a PCB board 10 is supported in the material support space 1425, ensuring the automation level of the material transfer mechanism 1.

[0054] In one embodiment, such as Figure 1 and Figure 2 As shown, the support column 1423 includes a column body 14231 and a limiting body 14232 connected to the column body 14231. The claw hook 1422 is installed at one end of the column body 14231 away from the limiting body 14232, and the column body 14231 is slidably inserted into the through hole 14241. The material support assembly 142 also includes a guide member 1427 rotatably installed on the limiting body 14232. It can be understood that the claw hook 1422 is located below the material support plate 1424, the limiting body 14232 is located above the limiting support plate, and neither the limiting body 14232 nor the claw hook 1422 can pass through the through hole 14241.

[0055] In one embodiment, such as Figure 1As shown, at least one guide component is installed on the support frame 13, and each guide component includes two guide brackets 15 symmetrically arranged; in the same guide component, a guide space for guiding the material support plate 1424 is provided between the two guide brackets 15; it can be understood that the guide groove 151 is provided on the side of the guide bracket 15 facing the guide space.

[0056] The material support mechanism 14 includes at least one material support component 142. Guide members 1427 are mounted on both sides of the end of the support column 1423 away from the claw hook 1422, and the guide members 1427 are connected to corresponding guide grooves 151. Understandably, the number of material support components 142 is equal to the number of guide components, and the material support components 142 and guide components are arranged in a one-to-one correspondence.

[0057] Specifically, during the process of the material support drive 141 driving the material support plate 1424 to move in the first direction, the guide support plate can move in the guide space between the two guide brackets 15, and the two guide members 1427 at opposite ends of the limiting part slide into the guide grooves 151 of the two guide brackets 15 respectively, which further improves the stability of the guide members 1427 sliding in the guide grooves 151 and increases the load-bearing capacity of the material support assembly 142.

[0058] In one embodiment, such as Figure 1 and Figure 3 As shown, the guide groove 151 includes a first groove 1511, an inclined groove 1512, and a second groove 1513 connected in sequence. Along a second direction perpendicular to the first direction, the first distance between the first groove 1511 and the material support plate 1424 is less than the second distance between the second groove 1513 and the material support plate 1424. It can be understood that the distance between the first groove 1511 and the bottom surface of the guide bracket 15 is less than the distance between the second groove 1513 and the bottom surface of the guide bracket 15. Both the first groove 1511 and the second groove 1513 extend along the first direction.

[0059] Specifically, when the guide member 1427 slides in the first groove 1511, the support column 1423 will not slide on the material support plate 1424. When the guide member 1427 slides in the inclined groove 1512, the support column 1423 slides in the through hole 14241, and the width of the material support space 1425 gradually decreases. When the guide member 1427 slides in the second groove 1513, the width of the material support space 1425 is at its minimum and remains unchanged, and the guide member 1427 can slide away from the guide groove 151 from the second groove 1513. In this embodiment, the design of the guide groove 151 allows the claw hook 1422 to gradually clamp the PCB board 10, ensuring the stability of the claw hook 1422 when it detaches from the PCB board 10.

[0060] In one embodiment, such as Figure 1 and Figure 3 As shown, the support frame 13 has a first end and a second end opposite to each other along the first direction. The limiting component 12 is disposed at the first end, and the guide bracket 15 is disposed at the second end. Understandably, the guide bracket 15 is located at the far end of the support frame 13, thereby allowing the material transfer mechanism 1 to move the larger PCB board 10 along the first direction. Furthermore, the cooperation between the material support component 14 and the guide bracket allows the material support component 14 to detach from the larger PCB board 10.

[0061] In one embodiment, such as Figure 4 and Figure 5 As shown, the limiting component 12 includes a limiting drive 121, a limiting sensor 122, a second elastic element 123, a locking element 124, and a limiting seat 125 with a blocking part 1251; the limiting drive 121 is mounted on the support frame 13 and connected to the limiting seat 125; it can be understood that the limiting drive 121 includes, but is not limited to, a linear motor, a pneumatic cylinder, and a hydraulic cylinder.

[0062] The locking member 124 is movably connected to the limiting seat 125 and forms a limiting groove 1252 with the blocking part 1251. The limiting groove 1252 has an opening at one end in the first direction away from the limiting seat 125 (i.e., the blocking part 1251). One end of the second elastic member 123 is connected to the limiting seat 125, and the other end is connected to the locking member 124. The locking member 124 moves relative to the limiting seat 125 through the second elastic member 123, so that the locking member 124 blocks or opens the opening of the limiting groove 1252. Understandably, the second elastic element 123 includes, but is not limited to, springs, etc., and the limiting sensor 122 includes, but is not limited to, laser sensors, photoelectric sensors, etc.; the blocking part 1251 and the locking member 124 are respectively located at opposite ends of the limiting groove 1252 along the first direction; when the locking member 124 moves upward and compresses the second elastic element 123, the locking member 124 will open the opening of the limiting groove 1252 away from the blocking part 1251; when the second elastic element 123 drives the locking member 124 downward, the locking member 124 will block the opening of the limiting groove 1252 away from the blocking part 1251.

[0063] The limit sensor 122 is mounted on the limit seat 125 and is used to detect whether the PCB board 10 is restricted in the limit groove 1252. It can be understood that the limit sensor 122 can be mounted on the inner wall of the limit groove 1252.

[0064] Specifically, such as Figure 9As shown, the PCB board 10 has two pins 101 spaced apart along a first direction. During the movement of the PCB board 10 along the first direction, the limiting drive member 121 drives the limiting seat 125 and the locking member 124 to move upwards. After the front pin 101 moves away from directly below the limiting assembly 12, the limiting drive member 121 drives the limiting seat 125 and the locking member 124 to move downwards. During the movement of the rear pin 101 along the first direction, it will press upwards against the locking member 124. The locking member 124 moves upwards and compresses the second elastic member 123. 124 opens the opening of the limiting groove 1252 away from the blocking part 1251. After the rear pin 101 moves into the limiting groove 1252, the second elastic member 123 will drive the locking member 124 to move downward, thereby the locking member 124 and the blocking part 1251 restrict the pin 101 in the limiting groove 1252. During the process of the material transfer drive member 11 driving the support frame 13 to move along the first direction, the locking member 124 will push the pin 101 along the first direction, thereby driving the PCB board 10 with the pin 101 installed to move along the first direction. In this embodiment, the limiting sensor 122 can detect in real time whether there is a pin 101 in the limiting groove 1252, ensuring that the material transfer mechanism 1 can stably transfer the PCB board 10 to the processing table 4.

[0065] In one embodiment, such as Figure 1 As shown, the material transfer mechanism 1 further includes a pressing assembly 16, which includes a top plate 161, a bottom plate 162, a synchronizing member 163, and pressing rollers 164 spaced apart on the bottom plate 162 along the first direction. The bottom plate 162 is slidably mounted on the top plate 161 along a second direction perpendicular to the first direction via the synchronizing member 163. The top plate 161 is mounted on the support frame 13, and the limiting drive member 121 is mounted on the bottom plate 162. It can be understood that multiple pressing rollers 164 are rotatably mounted on both the left and right sides of the bottom plate 162. The number of pressing rollers 164 can be set according to actual needs.

[0066] In this embodiment, during the movement of the PCB board 10 along the first direction, the pressure roller 164 can roll on the top surface of the PCB board 10, thereby pressing the PCB board 10 from above and preventing the PCB board 10 from tilting during its movement in the first direction, thus ensuring the stability of the PCB board 10's movement in the first direction. Furthermore, the design of the synchronization component 163 allows the base plate 162 to move as a whole along the second direction, preventing one end of the base plate 162 from tilting and ensuring the stability of the material transfer mechanism 1 in moving the PCB board 10 along the first direction.

[0067] In one embodiment, such as Figure 1 As shown, the PCB board 10 has a pin 101, and the bottom plate 162 has a guide groove 1621 extending along a first direction at one end opposite to the top plate 161. The pin 101 can move along the guide groove 1621. The limiting drive member 121 is used to drive the blocking part 1251 and the locking member 124 into or out of the guide groove 1621, so that the limiting groove 1252 limits or releases the pin 101. It can be understood that the guide groove 1621 is set on the ground of the bottom plate 162 and penetrates the bottom plate 162. In this embodiment, during the movement of the PCB board 10 along the first direction, the pin 101 slides in the guide groove 1621, so that the PCB board 10 will not deviate during the movement along the first direction, thus ensuring the accuracy of the transfer mechanism 1 in moving the PCB board 10.

[0068] In one embodiment, such as Figure 1 As shown, the synchronizing element 163 includes a synchronizing rod rotatably mounted on the base plate 162 along a first direction and at least two transmission components spaced apart along the first direction. Each transmission component includes a connecting shaft, a gear, a rack, a first helical gear, and a second helical gear. The connecting shaft is rotatably mounted on the top plate 161. The gear and the first helical gear are both sleeved on the connecting shaft. The rack is mounted on the base plate 162 and meshes with the gear. The second helical gear is sleeved on the synchronizing rod and meshes with the first helical gear. Understandably, the transmission components can be configured in two, three, or other ways depending on actual needs.

[0069] Specifically, when one end of the base plate 162 tilts upwards along the second direction, the base plate 162 will cause the rack to move upwards. The rack will then drive the first helical gear to rotate via the rack and the connecting shaft. The first helical gear will then drive the synchronizing rod to rotate via the second helical gear. The synchronizing rod will then drive all the second helical gears on it to rotate, thereby causing all the transmission components to move synchronously. This, in turn, causes the entire base plate 162 to move along the second direction, preventing the base plate 162 from tilting upwards at one end. In this embodiment, the synchronizing element 163 has a simple structure and low manufacturing cost; the design of the first and second helical gears ensures the stability of the base plate 162 moving along the second direction.

[0070] like Figure 6 and Figure 7As shown, another embodiment of this utility model also provides a feeding device, including a support mechanism 2 and the aforementioned transfer mechanism 1; the support mechanism 2 includes a support drive member 21, a first support frame 22, a second support frame 23, a plurality of first support wheels 24 rotatably mounted on the first support frame 22 along the first direction, and a plurality of second support wheels 25 rotatably mounted on the second support frame 23 along the first direction; the support drive member 21 is mounted on the first support frame 22 and connected to the second support frame 23, and is used to drive the second support frame 23 to move along the first direction; the first support wheels 24 and the second support wheels 25 are both used to support the PCB board 10. It can be understood that the first support frame 22 can be slidably mounted on the second support frame 23 along the first direction via a guide rail slider assembly; and the support mechanism 2 is located directly below the transfer mechanism 1.

[0071] Specifically, the support drive 21 drives the second support frame 23 to be in an extended state on the first support frame 22, and the PCB board 10 can be moved onto the support mechanism 2. The pressure roller 164 abuts against the top surface of the PCB board 10, and the first support roller 24 and the second support roller 25 abut against the bottom surface of the PCB board 10. The processing table 4 moves along the first direction and gradually retracts the second support frame 23 onto the first support frame 22. The PCB board 10, which is restricted by the transfer mechanism 1, is partially located above the processing table 4 and partially located below the transfer mechanism 1. The PCB board 10 is placed on the first support frame 22. The material transfer drive 11 pushes the PCB board 10 towards the processing table 4 through the limiting component 12 until the PCB board 10 is detached from the first support frame 22 and is completely positioned above the processing table 4. After the material support drive 141 drives the limiting component 12 to detach from the PCB board 10, the material support drive 141 drives the material support component 142 to move along the first direction until the material support component 142 detaches from the PCB board 10, and the PCB board 10 will fall onto the processing table 4, thus completing the automatic feeding function of the processing table 4. In this utility model, the feeding device can stably transport the PCB board 10 to the processing table 4, and the feeding mechanism has a compact structure and occupies little space.

[0072] like Figure 8 As shown, another embodiment of this utility model also provides a PCB processing equipment, including a bed 3, a processing table 4, and the above-mentioned feeding device; the processing table 4 is slidably mounted on the bed 3, and the feeding device is disposed at one end of the bed, the feeding device being used to transport the PCB board 10 to the processing table 4; the PCB processing equipment is a drilling machine, a forming machine, or a drilling and milling machine.

[0073] The above are merely embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
