[0035] It should be understood that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", and "middle" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description.

[0036] It should be noted that the first direction in this application is Figure 3 The X direction (i.e., the length direction of the guide plate) in the second direction is Figure 3 The Z direction (i.e., the height direction of the guide plate).

[0037] like Figure 1 and Figure 2 As shown, a material moving mechanism provided by an embodiment of the utility model is used to transport a workpiece 20 provided with a fixing member 10. The material moving mechanism includes an elastic member 1, a clamping member 2, and a clamping member 3 provided with a mounting groove 31. The elastic member 1 and the clamping member 2 are both installed in the mounting groove 31. One end of the elastic member 1 is connected to the bottom wall of the mounting groove 31, and the other end oppositely is connected to the clamping member 2. The fixing member 10 can drive the clamping member 2 to move, and then the clamping member 2 is extended and retracted in the mounting groove 31 through the elastic member 1. It can be understood that the workpiece 20 includes but is not limited to a circuit board, cardboard, etc. or any combination, and the fixing member 10 includes but is not limited to a pin sleeve, etc. The elastic member 1 includes but is not limited to a spring, a spring, etc. The top of the clamping member 2 is slidably installed in the mounting groove 31 and abuts against the elastic member 1, and the bottom of the clamping member 2 extends from the mounting groove 31.

[0038] A limiting arm 32 is also provided at one end of the clamping member 3, and a limiting groove 33 is formed between the limiting arm 32 and the clamping member 2. The material moving mechanism is configured to be able to move along a first direction, and the first direction X is the transportation direction of the workpiece 20. The limiting groove 33 is used to limit the fixing member 10 in the first direction X, and push the fixing member 10 to move along the first direction X through the clamping member 2 to realize the conveying of the workpiece 20. It can be understood that the limiting arm 32 is arranged at the bottom of the clamping member 3, and the limiting arm 32 and the clamping member 2 both extend toward the bottom of the clamping member 3.

[0039] In the utility model, a mounting groove 31 is provided on the clamping member 3, one end of the elastic member 1 is connected to the bottom wall of the mounting groove 31, and the other end opposite thereto is connected to the clamping member 2. A limiting arm 32 is also provided at one end of the clamping member 3, and a limiting groove 33 is formed between the limiting arm 32 and the clamping member 2. During the movement of the workpiece 20 provided with the fixing member 10 along the first direction X, the fixing member 10 will press the clamping member 2 upward, the clamping member 2 moves upward and compresses the elastic member 1, and after the fixing member 10 passes over the clamping member 2, the clamping member 2 moves downward due to the rebound force of the elastic member 1, so that the limiting arm 32 and the clamping member 2 can be clamped in the fixing member 10, that is, the fixing member 10 is limited in the limiting groove 33. During the movement of the material moving mechanism along the first direction X, the material moving mechanism will push the fixing member through the clamping member 2, thereby driving the workpiece 20 provided with the fixing member 10 to move along the first direction X. The material moving mechanism does not need to clamp the workpiece 20 to avoid damage to the workpiece 20, and the material moving mechanism has a simple structure and low manufacturing cost.

[0040] In one embodiment, if Figure 1 and Figure 2 As shown, the positioning member 3 has a first end, and the first end is an end of the positioning member 3 facing the workpiece 20 when the workpiece 20 is transported. It can be understood that the first end is the bottom of the positioning member 3.

[0041] A portion of the clamping member 3 protrudes from the first end to form a limiting arm 32, and the end of the clamping member 2 facing away from the elastic member 1 can protrude from the first end. In the first direction X, the clamping member 2 and the limiting arm 32 are arranged opposite to each other and surround to form a limiting groove 33. Specifically, the limiting arm 32 is a plate-like structure. In the first direction X, the orthographic projection of the clamping member 2 is within the orthographic projection of the limiting arm 32, so as to ensure that the limiting groove 33 formed by the clamping member 2 and the limiting arm 32 can limit the fixing member 10 in the first direction X. In this embodiment, the material shifting mechanism has a simple structure and low manufacturing cost.

[0042] In one embodiment, if Figure 1 and Figure 2 As shown, a guide portion 21 is provided at one end of the clamping member 2 away from the elastic member 1 and away from the limiting arm 32. In the process of transporting the workpiece 20, the fixing member 10 can abut against the guide portion 21 to allow the clamping member 2 to slide in the installation groove 31. Specifically, in the process of the workpiece 20 driving the fixing member 10 to move along the first direction X, the fixing member 10 can drive the clamping member 2 to move upward and compress the elastic member 1 through the guide portion 21, and the fixing member 10 can enter the limiting groove 33 after passing over the clamping member 2. In this embodiment, the design of the guide portion 21 ensures the stability of the fixing member 10 driving the clamping member 2 to slide in the installation groove 31, and at the same time avoids the collision between the fixing member 10 and the clamping member 2 so that the clamping member 2 does not move, resulting in the situation that the fixing member 10 cannot enter the limiting groove.

[0043] In one embodiment, if Figure 1 and Figure 2 As shown, the guide portion 21 is a guide slope, and in the first direction X, the distance between the guide slope and the end surface of the clamping member 2 connected to the elastic member 1 gradually increases (that is, from the end close to the limiting groove 33 to the end away from the limiting groove 33, the distance between the guide slope and the elastic member 1 gradually decreases). Specifically, during the movement of the fixing member 10 on the workpiece 20 toward the limiting groove 33, the fixing member 10 can drive the clamping member 2 to slide in the installation groove 31 through the guide slope.

[0044] In one embodiment, if Figure 1 and Figure 2As shown, the clamping member 2 has a transmission part, which is arranged at one end of the clamping member 2 close to the limiting arm 32 and located at one end of the clamping member 2 away from the elastic member 1. After the fixing member 10 is limited in the limiting groove 33, the transmission part can abut against the fixing member 10 and push the fixing member 10 to move, so as to drive the workpiece 20 to move. It can be understood that the transmission part is located at one end of the clamping member 2 facing the limiting groove 33. After the fixing member 10 is limited in the limiting groove 33, during the movement of the material moving mechanism along the first direction X, the transmission part abuts against the fixing member 10, so that the clamping member 2 will push the fixing member 10 to move along the first direction X through the limiting part.

[0045] In one embodiment, if Figure 2 As shown, the material moving mechanism has a second direction Z perpendicular to the first direction X. The material moving mechanism also includes a support seat 4 and a positioning driving member 5 installed on the support seat 4. The positioning member 3 is movably connected to the support seat 4. The positioning driving member 5 is connected to the end of the positioning member 3 away from the limiting groove 33, and is used to drive the positioning member 3 to move along the second direction Z.

[0046] In one embodiment, if Figure 3 and Figure 4 As shown, the material moving mechanism further includes a guide plate 6, the support seat 4 is mounted on the guide plate 6, and a guide groove 61 and a through groove 62 are provided on the guide plate 6. The guide groove 61 is provided at one end of the guide plate 6 away from the support seat 4, and penetrates the guide plate 6 along the first direction X. The through groove 62 is located at one end of the guide plate 6, and penetrates the guide plate 6 along the second direction Z and communicates with the guide groove 61. The guide groove 61 is used to limit the moving direction of the fixing member 10. It can be understood that the guide groove 61 is a long strip groove provided at the bottom of the guide plate 6, and the through groove 62 is provided at the top of the guide plate 6.

[0047] Further, the positioning drive member 5 can drive the positioning member 3 to move, thereby driving the limiting arm 32 and the clamping member 2 to enter or exit the guide groove 61 through the through groove 62. When the positioning drive member 5 drives the limiting arm 32 and the clamping member 2 to exit the guide groove 61 and move into the through groove 62 through the positioning member 3, the fixing member 10 can slide along the guide groove 61. Specifically, the positioning drive member 5 drives the positioning member 3 to move upward, thereby driving the limiting arm 32 and the clamping member 2 to retreat into the through groove 62, so that the limiting arm 32 and the clamping member 2 will not block the movement of the fixing member 10 in the guide groove 61. During the movement of the workpiece 20, the guide groove 61 can guide and limit the movement of the fixing member 10, ensuring that the fixing member 10 moves along the first direction X without deflection, so as to ensure the accuracy of the loading.

[0048] When the positioning driving member 5 drives the limiting arm 32 and the clamping member 2 to move into the guide groove 61 through the positioning member 3, the fixing member 10 can squeeze the clamping member 2 and be clamped in the limiting groove 33. Specifically, the positioning driving member 5 drives the positioning member 3 to move downward, and the limiting arm 32 and the clamping member 2 move into the guide groove 61. During the movement of the workpiece 20, the fixing member 10 on the workpiece 20 slides along the guide groove 61 until the fixing member 10 abuts against the clamping member 2. At this time, the fixing member 10 continues to move and squeezes the clamping member 2 to drive the clamping member 2 to slide upward, thereby enabling the fixing member 10 to move into the limiting groove 33. When the fixing member 10 is completely located in the limiting groove 33, the clamping member 2 returns to the initial position under the elastic force of the elastic member 1, so that the fixing member 10 is clamped in the limiting groove 33 by the clamping member 2 and the limiting arm 32. The initial position refers to the position where the clamping member 2 is located in the guide groove 61 and is not in contact with the fixing member 10. In this embodiment, the guide plate 6 is provided with a guide groove 61 to limit the movement of the fixing member 10, thereby ensuring the position accuracy of the workpiece 20 when it is transported to the loading device, and the loading device can drive the workpiece 20 to move along the extension direction of the guide groove 61, i.e., the first direction, through the material moving mechanism to complete the automatic loading of the workbench.

[0049] In one embodiment, if Figure 3 As shown, the guide plate 6 has a feed end, and the support seat 4 is arranged near the feed end. It can be understood that the feed end is an end where the workpiece 20 starts to be conveyed to the material moving mechanism.

[0050] The material shifting mechanism further includes a guide member 8 and a locking member 7 slidably connected to the guide member 8, the guide member 8 extends along the first direction X and is arranged at the feeding end, and the support seat 4 is connected to the guide member 8 through the locking member 7. It can be understood that the locking member 7 includes but is not limited to a lock, a magnetic lock, etc., and the locking member 7 can achieve locking or unlocking between the support seat 4 and the guide member 8, so that the support seat 4 can be installed at different positions of the guide member 8.

[0051] In some embodiments, in the first direction X, the length of the guide member 8 is greater than the length of the through slot 62 .

[0052] Specifically, the position of the support seat 4 on the guide member 8 can be adjusted by the locking member 7. Since the length of the guide member 8 is greater than the length of the through slot 62, the support seat 4 can be set at any position corresponding to the through slot 62, so that the locking member 3 can be inserted in any position of the through slot 62, so that the clamping member 2 and the limiting arm 32 on the clamping member 3 can be adapted to the fixing members 10 at different positions on the workpiece 20, thereby improving the flexibility and practicality of the material moving mechanism.

[0053] Another embodiment of the utility model further provides a feeding device, including a mobile driving member (not shown in the figure) and the above-mentioned material shifting mechanism, wherein the mobile driving member is connected to the clamping member 3, and the mobile driving member can drive the clamping member 3 to move along the first direction X. It can be understood that the mobile driving member includes but is not limited to a linear motor, a pneumatic cylinder, and a hydraulic cylinder. Specifically, when the fixing member 10 on the workpiece 20 is clamped in the limiting groove 33, the mobile driving member drives the material shifting mechanism to move, and the fixing member 10 is pushed by the clamping member 2 to drive the workpiece 20 to move, thereby completing the automatic feeding function between the workpiece 20 and the workbench, with a simple structure and low manufacturing cost. Moreover, since the material shifting mechanism does not directly contact the workpiece 20, the material shifting mechanism will not directly damage the workpiece 20 during the feeding process, thereby improving the product yield.

[0054] In one embodiment, if Figure 6 and Figure 7 As shown, the workpiece 20 is a circuit board assembly, such as a PCB board assembly, and the fixing member 10 is a pin sleeve, and the PCB board assembly is combined into one by the pin sleeve. Specifically, the PCB board assembly includes a backing plate and multiple PCB boards stacked on the backing plate, and the backing plate and the multiple PCB boards are combined into one by the pin sleeve.

[0055] Further, the pin sleeve includes a first cylinder 101 and a second cylinder 102 which are coaxially arranged, and the outer diameter of the first cylinder 101 is smaller than the outer diameter of the second cylinder 102. The PCB board assembly is provided with a pin hole, the first cylinder 101 is inserted in the pin hole, the second cylinder 102 is exposed in the pin hole and abuts against one end of the PCB board assembly, the second cylinder 102 can drive the clamping member 2 to move in the installation groove 31, and the limiting groove 33 is used to limit the second cylinder 102 in the first direction X, and push the second cylinder 102 to move along the first direction X through the clamping member 2 to drive the board assembly to move. Specifically, the outer diameter of the first cylinder 101 is greater than or equal to the inner diameter of the pin hole, so that the first cylinder 101 and the pin hole are interference fit to ensure the fixing effect. And the outer diameter of the second column 102 is larger than the outer diameter of the first column 101, that is, the outer diameter of the second column 102 is larger than the inner diameter of the pin hole. When installing the fixing member 10, the first column 101 is inserted into the pin hole until the second column 102 abuts against the end face of the workpiece 20, which means that the fixing member 10 is installed in place, which simplifies the difficulty of assembly. At the same time, during transportation or processing, it prevents the fixing member 10 from falling off due to contact, thereby ensuring the overall stability of the PCB board assembly.

[0056] The feeding process of the present application is roughly as follows: when the PCB board assembly provided with the pin sleeve is moved to the feeding device along the first direction X by manual or external conveying equipment (AGV trolley, etc.), the positioning driving member 5 drives the positioning member 3 to move downward, the limiting arm 32 and the clamping member 2 move into the guide groove 61, and the second column 102 of the pin sleeve slides along the guide groove 61, thereby ensuring the stability and position accuracy of the workpiece 20 when it is transferred to the feeding device. After the second column 102 on the pin sleeve abuts against the clamping member 2, the second column 102 continues to move and squeezes the clamping member 2 to move the clamping member 2 upward, and then after the second column 102 moves to the limiting groove 33, the clamping member 2 returns to the initial position through elastic force, and cooperates with the limiting arm 32 to limit the second column 102 in the limiting groove 33, thereby completing the material preparation action of the feeding device. Finally, the moving driving member drives the material moving mechanism to move along the first direction X, and the clamping member 2 abuts against the second column 102 to drive the workpiece 20 to move, so as to move the workpiece 20 to the workbench, thereby completing the automatic loading function of the workbench.

[0057] like Figure 5 As shown, this embodiment also provides a circuit board forming machine, including the above-mentioned feeding device. The circuit board forming machine also includes a machine tool 101 and a processing device 102, the feeding device and the processing device 102 are both installed on the machine tool 101, the machine tool 101 has a feeding area and a processing area arranged at intervals, the processing device 102 is arranged corresponding to the processing area, the feeding device is arranged corresponding to the feeding area, and can move the workpiece 20 to the processing area, wherein the worktable is movably connected to the machine tool 101, and can receive the workpiece 20 transported by the feeding device.

[0058] The above are merely embodiments of the material transfer mechanism of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
