Description

Technical Field

[0001] This utility model relates to the field of stamping-related equipment, specifically to a parts transfer mechanism. Background Technology

[0002] After stamping, the parts need to be taken out of the stamping station and transferred to the next station for subsequent processing. The speed at which the parts are taken out of the stamping station and transferred to the next station is also closely related to the overall processing efficiency of the parts.

[0003] Current transfer equipment, as shown in the punching and transferring equipment disclosed in patent number CN209701783U, includes a chassis, a punching device mounted on the chassis, a transferring device mounted on the chassis, and a suction cup connected to the transferring device; the chassis has a material inlet and a material outlet, and also has a finished product placement area; the punching device includes a die, a punch corresponding to the die, and a lifting driver for driving the punch closer to or away from the die; the die is corresponding to the material inlet, and the die has a discharge port corresponding to and connected to the material inlet; the transferring device is used to drive the suction cup to move between the punching device, the material outlet, and the product placement area.

[0004] The aforementioned device is equipped with a vertical drive unit and a longitudinal drive unit. During operation, the vertical drive unit drives the suction cup to move along the Z direction, and the longitudinal drive unit drives the suction cup to move along the Y direction. The design of multiple power sources makes the structure of the entire device complex. Furthermore, when using a computer to achieve automated control, the control program is also quite complex, resulting in high difficulty in program design and high cost of the equipment. Utility Model Content

[0005] The present invention aims to provide a parts transfer mechanism to solve the problem that existing material handling equipment requires the design of multiple power sources, resulting in complex structure and high cost.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a parts transfer mechanism, comprising a driver, a cam unit, a transverse guide unit, a track unit, and a clamp. The transverse guide unit includes a guide member and a transverse slider. The guide member is horizontally arranged, and the transverse slider slides in cooperation with the guide member. The track unit includes a mounting block and two vertical tracks. The two vertical tracks are vertically arranged and both slide in cooperation with the transverse slider. The cam unit includes a rocker arm and a back plate. The driver is connected to the rocker arm and is used to drive the rocker arm to rotate. The mounting block includes a first mounting part and two second mounting parts fixedly connected to each other. The two second mounting parts are located on both sides of the first mounting part, and the thickness of the two second mounting parts is less than that of the first mounting part. The side wall of the first mounting part facing the swing arm is in contact with the swing arm. The two vertical rails are detachably connected to the two first mounting parts respectively. The cross-section of the vertical rails is I-shaped. The swing arm is eccentrically provided with a strip groove and a rotating shaft. The first mounting part is opposite to the strip groove. The rotating shaft passes through the first mounting part and slides in cooperation with the strip groove. The back plate is provided with an inverted U-shaped through groove. The end of the rotating shaft away from the mounting block extends into the through groove and can slide along the through groove. The first mounting part and the swing arm can rotate relative to each other. The clamp is installed below the vertical rail.

[0007] The beneficial effects of this plan are:

[0008] 1. In this solution, the driver rotates the swing arm, which in turn moves the mounting block via a rotating shaft. Due to the limitation imposed by the through groove, the shaft first moves upwards along the vertical section of the groove, causing the vertical track to move upwards and lifting the workpiece using the clamp. As the shaft rotates to the horizontal section of the groove, it moves the vertical track horizontally. At this point, the horizontal slider moves horizontally along the guide, automatically transferring the workpiece to the next station. When the shaft slides downwards along another vertical section of the groove, it moves the clamp downwards, automatically placing the workpiece into the next station. Therefore, this solution uses only one driver to achieve the process of removing the workpiece from the previous station and transferring it horizontally to the next station. That is, a single driver can achieve both vertical and horizontal movement of the workpiece, eliminating the need for two separate power sources for vertical and horizontal movement, making control simpler and reducing costs.

[0009] 2. This design includes two vertical tracks, which are located on both sides of the first mounting section. This makes the mounting block in this design more evenly stressed and runs more smoothly. It also prevents the structure from deforming or jamming due to prolonged operation under uneven stress.

[0010] 3. The mounting block in this design includes a first mounting part and two second mounting parts. The thickness of the first mounting part is greater than that of the second mounting parts, creating an L-shaped mounting space between them for installing the vertical track. The side wall of the first mounting part limits the vertical track, facilitating the alignment of the vertical track with the second mounting parts and improving the installation efficiency of the vertical track. Furthermore, the greater thickness of the first mounting part allows its side wall near the swing arm to fit snugly against the swing arm, improving the installation stability between the swing arm and the first mounting part.

[0011] Furthermore, a limiting block is detachably connected to the horizontal slider. The horizontal slider has several mounting holes along the horizontal direction, and the limiting block has a limiting hole that can be aligned with any of the mounting holes. The vertical track slides in cooperation with the limiting block.

[0012] The beneficial effects of this solution are as follows: By aligning the limiting hole with mounting holes at different positions, the limiting block and the horizontal slider can be fixed at different positions, thereby adjusting the position of the vertical track laterally. When used in devices with different swing arm lengths, it ensures that the position of the vertical track is aligned with the through slot of the device, guaranteeing that the movement will not be interfered with. Therefore, setting the dimensions of the horizontal guide unit in each specification of the device to be the same allows for universal compatibility across different specifications, thus reducing costs.

[0013] Furthermore, the sidewall of the vertical track forms a guide groove extending along the length direction, and the limiting block is fixed to the sidewall of the vertical track with a guide block, the guide block being located in the guide groove and being able to slide along the guide groove.

[0014] The beneficial effects of this solution are as follows: the guide block and guide groove in this solution cooperate to allow the vertical track to slide vertically relative to the limiting block, while the guide block can also limit the vertical track and prevent the vertical track from detaching forward.

[0015] Furthermore, the horizontal slider includes a mounting plate and a sliding part, with mounting holes located on the mounting plate and fixing holes on the sliding part that can be aligned with any of the mounting holes.

[0016] The beneficial effects of this solution are: by aligning the fixing hole with different mounting holes, the horizontal slider can be installed in different positions, thereby changing the installation position of the horizontal slider and realizing the adjustment of the vertical track along the horizontal direction.

[0017] Furthermore, an extension rod is installed at the lower part of the vertical track. The extension rod extends axially along the pivot, and the clamp is installed on the extension rod with its vertical projection located in front of or behind the vertical track.

[0018] The beneficial effects of this solution are as follows: the clamp can be installed in front of the vertical track by means of the extension rod. Therefore, when the device in this solution is installed, the cam unit, the transverse guide unit and other structures can be installed on the rear or front side of the mold, so as not to obstruct the placement of the workpiece and the movement of the mold, making the processing more convenient.

[0019] Furthermore, a connecting rod is fixed between the two vertical tracks, and the extension rod is fixed to the middle of the connecting rod.

[0020] The beneficial effect of this solution is that the connecting rod enables the two vertical rails to support the clamp simultaneously, making the installation of the clamp more stable. Attached Figure Description

The cam unit includes a rocker arm 3 and a back plate 2. The back plate 2 is vertically mounted on the frame 1 by bolts. The back plate 2 has an inverted U-shaped through groove 21, which includes two vertical grooves and one transverse groove. The driver is a forward and reverse reversible motor, mounted on the frame 1, and its output shaft passes through the back plate 2 and has a bearing between it and the back plate 2. The left end of the rocker arm 3 has a strip groove 31, in which a rotating shaft is slidably fitted. The rear end of the rotating shaft extends into the through groove 21 and can slide along the through groove 21. The right end of the rocker arm 3 is interference-fitted with a shaft, and the output shaft of the driver is connected to the shaft via a coupling to drive the rocker arm 3 to swing.

[0029] The track unit is located below the back plate 2. The track unit includes a mounting block 4 and two vertical tracks 5. The mounting block 4 includes an integrally formed first mounting part 41 and two second mounting parts 42. The two second mounting parts 42 are located on the left and right sides of the first mounting part 41, respectively. The thickness of the first mounting part 41 is greater than the thickness of the second mounting parts 42, and the front sidewall of the first mounting part 41 and the front sidewall of the second mounting part 42 are on the same plane. Therefore, the left and right sidewalls of the first mounting part 41 and the two second mounting parts 42 respectively form two L-shaped mounting spaces. In this embodiment, the first mounting part 41 is opposite to the strip groove 31, and the rear sidewall of the first mounting part 41 is in contact with the swing rod 3 and connected to the rotating shaft by bolts. The first mounting part 41 is also provided with a groove 43, and the head of the bolt is located in the groove 43.

[0030] Both vertical rails 5 are vertically arranged and located within two L-shaped installation spaces. The vertical rails 5 abut against the second mounting portion 42 and are mounted on the second mounting portion 42 with screws. The lower ends of the vertical rails 5 extend to the bottom of the back plate 2. The horizontal cross-section of both vertical rails 5 is I-shaped, forming guide grooves 51 on both the left and right sidewalls of the vertical rails 5. Limiting blocks 9 are provided on both the left and right sides of the two vertical rails 5. Guide blocks 91 are integrally formed on the sidewalls of the limiting blocks 9 facing the vertical rails 5. The guide blocks 91 are located within the guide grooves 51 and can slide relative to the guide grooves 51.

[0031] The lateral guide unit is located below the back plate 2. The lateral guide unit includes a guide member 11 and a lateral slider. The guide member 11 is a slide rail and is horizontally mounted on the frame 1 by screws. The lateral slider includes a mounting plate 12 and two sliding parts 14. The mounting plate 12 is in contact with the guide member 11. The mounting plate 12 has two sets of mounting holes, each set including several mounting holes 13, and all mounting holes 13 in the same set are evenly distributed horizontally. Each sliding part 14 has two sets of fixing holes, each set including two fixing holes. The distance between the two fixing holes is the same as the distance between two adjacent mounting holes 13 in the same set, so that the two upper fixing holes can be aligned with any two upper mounting holes 13, and the two lower fixing holes can be aligned with any two lower mounting holes 13. Bolts are used to pass through the aligned mounting holes 13 and fixing holes to fix the mounting plate 12 and the sliding parts 14. The limiting block 9 is provided with two fixing holes. The two fixing holes are distributed vertically and can be aligned with any two vertically distributed mounting holes 13 on the mounting plate 12, and are installed on the mounting plate 12 by screws.

[0032] A connecting rod 6 is provided at the lower part of the vertical track 5. The connecting rod 6 is horizontally arranged and its two ends are connected to the two vertical tracks 5 respectively by screws. An extension rod 7 is also welded to the middle of the connecting rod 6. The extension rod 7 extends along the thickness direction of the back plate 2, so that the front end of the extension rod 7 is located in front of the vertical track 5. The clamp 8 is installed at the front end of the extension rod 7. In this embodiment, the clamp 8 adopts an existing suction cup. In actual implementation, the clamp 8 can also adopt an existing gripper. Specifically, the type of clamp 8 is determined according to the type and shape of the workpiece to be clamped, as long as it can clamp the workpiece.

[0033] The specific implementation process is as follows:

[0034] In this embodiment, when the mechanism is in use, the back plate 2 and the vertical track 5 are located on the rear side of the mold, and the clamp 8 is opposite to the workpiece to be clamped inside the mold. Initially, the swing rod 3 is horizontal, and the left end of the swing rod 3 is opposite to the lower end of the left side of the through groove 21. At this time, the clamp 8 extends into the mold to clamp the workpiece.

[0035] Then, the driver is activated, causing the rocker arm 3 to rotate clockwise. The rocker arm 3 drives the rotating shaft to slide upward along the vertical part on the left side of the through groove 21. At the same time, the rotating shaft slides relative to the rocker arm 3 along the strip groove 31, causing the vertical track 5 to move upward and remove the workpiece from the mold. As the rocker arm 3 continues to rotate, the rotating shaft slides to the horizontal part of the through groove 21, causing the vertical track 5 to move horizontally. At this time, the horizontal slider slides horizontally to the right along the guide 11, moving the workpiece above the next station.

[0036] Finally, the rotating shaft slides downwards along the vertical section on the right side of the through groove 21, causing the vertical track 5 to slide downwards and placing the workpiece into the next station, thus realizing the transfer of the workpiece from the previous station to the next station. Finally, the drive component controls the swing arm 3 to reset counterclockwise, causing the vertical track 5 to reset to the left.
