Description

Technical Field

[0001] This invention relates to the field of clamping technology, and more specifically, to a transfer clamp. Background Technology

[0002] In the process of placing the filter sheet into the injection mold and then injection molding it into a finished product, multiple transfer fixtures are required. The transfer fixtures are installed on the robotic arm. Through the movement of the robotic arm, one transfer fixture is responsible for removing the finished product from the injection mold, while another transfer fixture can pick up the filter sheet and place it back into the injection mold for processing.

[0003] In actual production, because the filter sheets are soft and thin, they are not easy to hold and carry stably. When the filter sheets are transferred to the injection mold, they are easy to fall off, causing production interruption and material loss. Or, multiple sheets are picked up at once, resulting in filter waste and affecting subsequent injection molding operations, which in turn affects production efficiency. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] Therefore, the present invention proposes a transfer fixture, including a frame, support columns, abutment, drive assembly, side plates and pressure plates.

[0006] Support columns are installed on the side walls of the frame; abutments are installed on the ends of the support columns away from the frame; a drive assembly is installed on the side of the abutments close to the frame; side plates are installed on the drive assembly, which has two symmetrically arranged side plates, located on opposite sides of the abutments; and pressure plates are installed on the side plates away from the frame.

[0007] The drive assembly can drive the two pressure plates to reciprocate relative to the back plate in a third direction and to open and close in a first direction, clamping the filter sheet between the pressure plates and the back plate, or releasing the filter sheet from between the pressure plates and the back plate.

[0008] The present invention proposes a transfer clamp in which the front abutment plate first presses the filter sheet to flatten it, and the driving component then drives the two pressure plates to close in opposite directions along a first direction. The side plates abut against both sides of the filter sheet to achieve auxiliary centering. At the same time, the pressure plates extend into the underside of the filter sheet and then move towards the abutment plate along a third direction, so as to stably clamp the filter sheet between the pressure plates and the abutment plate.

[0009] The action of flattening, centering, and then lifting and clamping effectively avoids the problem of multiple filters being picked up together when taking out the filter compared to existing technologies; the clamping method of the pressure plate and the backing plate provides uniform and stable clamping force, ensuring that the filter is firmly clamped and accurately placed during the transfer process.

[0010] In addition, it is equipped with multiple pairs of swingable grippers to remove the processed products from the injection mold, and an industrial camera is also provided to facilitate visual inspection of the filter sheets placed on the injection mold, ensuring positional accuracy. This allows a single set of transfer fixtures to complete the functions of picking up, unloading, and inspection, making it more functional.

[0014] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

[0017] Please see Figures 1 to 7 A transfer clamp is provided, including a frame 100, a support column 200, a backing plate 300, a drive assembly 400, side plates 500, and a pressure plate 600. The support column 200 is mounted on the side wall of the frame 100; the backing plate 300 is mounted on the end of the support column 200 away from the frame 100; the drive assembly 400 is mounted on the side of the backing plate 300 near the frame 100; the side plates 500 are mounted on the drive assembly 400, and the drive assembly 400 has two symmetrically arranged side plates 500, which are located on opposite sides of the backing plate 300; the pressure plate 600 is mounted on the side of the side plates 500 away from the frame 100; wherein, the drive assembly 400 can drive the two pressure plates 600 to reciprocate relative to the backing plate 300 along a third direction and to open and close along a first direction, clamping a filter sheet 10 between the pressure plate 600 and the backing plate 300, or releasing the filter sheet 10 from between the pressure plate 600 and the backing plate 300.

[0018] In this embodiment, the transfer fixture includes a frame 100, a support column 200, a backing plate 300, a drive assembly 400, a side plate 500, and a pressure plate 600.

[0019] Frame 100 is composed of several plates connected together, providing accurate installation positions for other components.

[0020] The support column 200 is installed on the side wall of the frame 100; the support column 200 is used to install the abutment plate 300, so that there is a gap between the abutment plate 300 and the frame 100, leaving space for the arrangement of the drive assembly 400.

[0021] The abutment 300 is installed at the end of the support column 200 away from the frame 100; the abutment 300 serves as a fixed reference surface for clamping the filter 10, and can ensure the flatness of the filter 10 before the clamping action.

[0022] Optionally, five support columns 200 are connected and installed between the abutment 300 and the frame 100, with four support columns 200 located at the four corners of the abutment 300 and one support column 200 located at the center of the abutment 300, further ensuring the strength of the abutment 300.

[0023] The drive assembly 400 is mounted on the side of the back plate 300 near the frame 100; the drive assembly 400 is used to move the side plate 500 and the pressure plate 600.

[0024] The side plate 500 is installed on the drive assembly 400. The drive assembly 400 has two side plates 500 symmetrically arranged, and the two side plates 500 are located on both sides of the abutment plate 300 respectively. The drive assembly 400 can move the two side plates 500 at the same time to achieve symmetrical movement of the two side plates 500.

[0025] The pressure plate 600 is installed on the side of the side plate 500 away from the frame 100; optionally, the pressure plate 600 and the side plate 500 are integrally bent into an L-shaped plate, and the pressure plate 600 moves with the side plate 500, and can clamp and release the filter 10 in cooperation with the abutment plate 300.

[0026] The drive assembly 400 can drive the two pressure plates 600 to reciprocate relative to the abutment 300 along a third direction and to open and close along a first direction, clamping the filter 10 between the pressure plate 600 and the abutment 300, or releasing the filter 10 from between the pressure plate 600 and the abutment 300.

[0027] In the first operating condition, the two pressure plates 600 move away from the abutment 300 along a third direction, and the two pressure plates 600 open away from each other along a first direction. This position is in the initial standby state.

[0028] In the second operating condition, the drive assembly 400 first drives the two pressure plates 600 to close close to each other along the first direction, and the two side plates 500 abut against the two sides of the filter sheet 10 for auxiliary centering. The two pressure plates 600 extend into the lower side of the filter sheet 10. The drive assembly 400 then drives the two pressure plates 600 to move closer to each other relative to the abutment plate 300 along the third direction, clamping the filter sheet 10 between the two pressure plates 600 and the abutment plate 300.

[0029] Please see Figure 4In some embodiments of the present invention, optionally, the drive assembly 400 includes a telescopic member 410, a connecting plate 420, and a clamping member 430. The telescopic member 410 is mounted on the abutment plate 300 and includes a first output rod facing the frame 100; the connecting plate 420 is mounted on the telescopic member 410; the clamping member 430 is mounted on the connecting plate 420 and includes two second output rods that are movable in opposite directions, and side plates 500 are respectively mounted on the ends of the two second output rods that are far apart from each other.

[0030] In this embodiment, the drive assembly 400 includes a telescopic component 410, a connecting plate 420, and a clamping component 430.

[0031] The telescopic component 410 is installed on the back plate 300. The telescopic component 410 includes a first output rod facing the frame 100. The telescopic component 410 is used to drive the connecting plate 420 and the clamping component 430 to reciprocate along a third direction, and control the distance between the pressure plate 600 and the back plate 300 to clamp or loosen the filter 10.

[0032] The connecting plate 420 is mounted on the telescopic component 410; the connecting plate 420 provides an installation position for the clamping component 430 and can transmit the power on the telescopic component 410 to the clamping component 430.

[0033] The clamping component 430 is mounted on the connecting plate 420. The clamping component 430 includes two second output rods that can move in opposite directions. The ends of the two second output rods that are far apart from each other are respectively equipped with side plates 500. The clamping component 430 drives the two side plates 500 and the pressure plate 600 to open and close symmetrically, assisting in centering and clamping the filter 10.

[0034] Optionally, the clamping component 430 can be a parallel pneumatic gripper, an opposing pneumatic cylinder, an electric parallel gripper, or an opposing electric linear actuator, etc. The power forms and transmission structures are different, but they can all realize the function of opposing movement of the two second output rods, which is convenient for specific selection according to the on-site air source conditions or accuracy requirements.

[0035] For example, a counter-cylinder includes a cylinder body and two pistons. The two pistons are connected to two output rods respectively. The pistons are driven by air pressure to move the two output rods in opposite directions (i.e., moving closer to each other or moving away from each other).

[0036] Please see Figure 4In some embodiments of the present invention, the drive assembly 400 may optionally further include a first reference post 440, a first position sensor 450, a second reference post 460, and a second position sensor 470.

[0037] In this embodiment, the drive assembly 400 further includes a first reference post 440, a first position sensor 450, a second reference post 460, and a second position sensor 470.

[0038] The first reference post 440 is installed on the abutment plate 300; the end of the first reference post 440 away from the abutment plate 300 serves as the detection reference for the first position sensor 450.

[0039] The first position sensor 450 is mounted on the connecting plate 420, with the detection end of the first position sensor 450 facing the first reference post 440. When the connecting plate 420 moves to the closest position along the third direction towards the abutment plate 300, the first position sensor 450 detects the first reference post 440, feeds back the position information, and stops the telescopic component 410 from continuing to shorten. At this time, the distance between the pressure plate 600 and the abutment plate 300 is sufficient to release the filter 10.

[0040] The second reference post 460 is installed on the connecting plate 420; the end of the second reference post 460 away from the abutment plate 300 serves as the detection reference for the second position sensor 470.

[0041] The second position sensor 470 is mounted on the frame 100, with its detection end facing the second reference post 460. When the connecting plate 420 moves away from the abutment plate 300 along a third direction to its farthest position, the second position sensor 470 detects the second reference post 460, provides position information, and stops the telescopic component 410 from extending further. At this time, the distance between the pressure plate 600 and the abutment plate 300 is sufficient to clamp the filter sheet 10.

[0042] Optionally, the first position sensor 450 and the second position sensor 470 are inductive proximity switches, photoelectric proximity switches or capacitive proximity switches, etc. When using inductive proximity switches, a first reference post 440 and a second reference post 460 made of ferromagnetic metal are required.

[0047] The gripper 730 is installed on the side of the swing assembly 720 away from the abutment 300, and two grippers 730 on each pair of first through holes are arranged opposite to each other; the two grippers 730 can swing in opposite directions.

[0048] The swing assembly 720 can drive the two grippers 730 to swing in opposite directions to clamp or release the product 20; the transfer fixture can also remove the processed product 20 from the injection mold before placing the filter 10 on the injection mold, thus achieving more functions.

[0049] Please see Figure 6In some embodiments of the present invention, optionally, the swing assembly 720 includes a sleeve 721, a cylinder 722, a first connecting rod 723, a clamping block 724, and a second connecting rod 725.

[0051] The sleeve 721 passes through the first through hole and the retainer 710, and the retainer 710 clamps the sleeve 721; the sleeve 721 is clamped and fixed by the retainer 710, serving as the basis for setting other components.

[0052] Cylinder 722 is installed at one end of sleeve 721 near the abutment 300. Cylinder 722 includes a piston rod that extends into sleeve 721. Cylinder 722 can transmit linear driving force into sleeve 721 through piston rod as power to drive first connecting rod 723.

[0053] The first connecting rod 723 is rotatably mounted on the end of the sleeve 721 away from the cylinder 722; the first connecting rod 723 can swing at the end of the sleeve 721 away from the cylinder 722.

[0054] The clamping block 724 is installed at the end of the first connecting rod 723 away from the cylinder 722; the clamping block 724 can swing with the first connecting rod 723.

The second connecting rod 725 is used to transmit the power of the reciprocating movement of the cylinder 722 to the first connecting rod 723, thereby realizing the movement of the swinging clamping block 724. The first connecting rod 723 and the second connecting rod 725 are distributed in a V-shape to avoid the first connecting rod 723 and the second connecting rod 725 being distributed on the same straight line, which would cause the movement to jam.

[0056] Please see Figure 7In some embodiments of the present invention, optionally, the clamping block 724 has a second through hole, and the transfer clamp further includes a pad 810, a screw 820, and a nut 830. The pad 810 abuts against the clamping block 724; the screw 820 is installed on the pad 810 and passes through the second through hole; the nut 830 is screwed to the screw 820 and abuts against the side of the clamping block 724 away from the pad 810.

[0057] In this embodiment: the clamping block 724 has a second through hole, and the transfer clamp also includes a pad 810, a screw 820 and a nut 830.

[0058] The pad 810 abuts against the clamping block 724; the pad 810 is used to contact the product 20 and increase the friction of the clamping block 724 in holding the product 20.

[0059] The screw 820 is mounted on the pad 810 and passes through the second through hole; optionally, four screws 820 are fitted into the side of the pad 810 near the clamping block 724 to provide threaded engagement for locking the nut 830. Nut 830 is screwed onto screw 820 and abuts against the side of clamp 724 away from pad 810; nut 830 is used to connect screw 820 to achieve precise installation of pad 810 and facilitate maintenance and replacement.

[0060] Optionally, the pad 810 may be made of polyurethane, nylon or silicone to suit wear-resistant, slip-resistant and high-temperature-resistant applications.

[0061] Please see Figure 7 In some embodiments of the present invention, optionally, a V-groove 840 is provided on the side of the pad 810 away from the clamping block 724. The V-groove 840 consists of two grooves arranged in a cross shape and is used to contact the product 20.

[0062] In this embodiment: a V-groove 840 is provided on the side of the pad 810 away from the clamping block 724. There are two V-grooves 840 distributed in a cross shape for contacting the product 20. When the pads 810 on both sides clamp the product 20, the V-groove 840 facilitates the edge of the product 20 to slide into the depth of the V-groove 840, thereby improving the clamping firmness. When one V-groove 840 is worn due to long-term use, the pad 810 can be rotated 90° to use the other V-groove 840 to contact the product 20, thereby extending the service life of the pad 810.

[0063] Please see Figure 2In some embodiments of the present invention, optionally, the number of abutment plates 300 is two arranged side by side, and each abutment plate 300 is provided with two drive components 400; the grippers 730 are provided with four pairs, and the position of each pair of grippers 730 holding the product 20 corresponds to the position of the pressure plate 600 and the abutment plate 300 holding the filter 10.

[0064] In this embodiment: the number of abutment plates 300 is two arranged side by side, and each abutment plate 300 is provided with two drive components 400; so that the transfer fixture has a clamping station for four filter plates 10, which can clamp four filter plates 10 at a time, improve the efficiency of single transfer, and is compatible with injection molds.

[0065] The gripper 730 is provided with four pairs of grippers. The position of each pair of grippers 730 holding the product 20 corresponds to the position of the pressure plate 600 and the abutment plate 300 holding the filter 10. This makes the transfer fixture have four gripping stations for the product 20, and can hold four products 20 processed from four filter 10 on the injection mold at one time.

[0066] Please see Figure 2 In some embodiments of the present invention, the transfer fixture may optionally include an industrial camera 900, which is mounted on one side of the frame 100.

[0067] In this embodiment, the transfer fixture also includes an industrial camera 900, which is mounted on one side of the frame 100. The industrial camera 900 is used in conjunction with the vision processing unit to perform visual inspection and position detection of the four filter sheets 10 placed on the injection mold, so as to avoid the placement position from being offset, thereby affecting the subsequent injection molding operation and further increasing the function of the transfer fixture.

[0068] Please see Figure 2 In some embodiments of the present invention, the transfer fixture may optionally include a docking plate 110, which is mounted on one side of the frame 100.

[0069] In this embodiment, the transfer fixture also includes a docking plate 110, which is installed on one side of the frame 100. The docking plate 110 is used to connect to the output plate of the robotic arm, so that the transfer fixture can be installed on the robotic arm and the robotic arm can move and flip the transfer fixture.

[0070] Optionally, the docking plate 110 is the tool plate in the quick-change plate, and the output plate of the robotic arm is the main plate in the quick-change plate. The quick-change plate can quickly connect the tool plate and the main plate by locking with a chuck, and realize the connection of the air circuit and the electrical circuit, and is easy to disassemble.

[0072] In one embodiment, the process of the robotic arm using a transfer fixture to transfer the filter 10 and the product 20 is as follows: The robotic arm drives the frame 100 connected to the docking plate 110 to move to the filter 10 that was placed in the previous process, and the drive component 400 drives the pressure plate 600 to the initial state.

[0073] Then, the lower plate 300 is moved down to press the filter 10 flat. The pressure plate 600 closes along the first direction to center the filter 10, and then moves along the third direction closer to the lower plate 300 so that the pressure plate 600 and the lower plate 300 cooperate to clamp the filter 10.

[0074] The transfer fixture is flipped 180° so that the gripper 730 is facing downwards. Then the transfer fixture is moved to the injection mold. The swing assembly 720 drives the gripper 730 to swing and close in opposite directions, clamping the product 20 on the mold.

[0075] The transfer fixture is flipped 180° again, with the pressure plate 600 facing downwards. The gripper 730 holds the product 20 in place, temporarily storing the product 20. The drive assembly 400 controls the pressure plate 600 to release and reset, placing the filter 10 into the injection mold.

[0076] The 90° flip transfer fixture is used to position the industrial camera 900 downwards, allowing the industrial camera 900 to perform position detection and verification on the filter 10.

[0077] The robotic arm drives the transfer fixture away from the injection mold station, rotates the transfer fixture 90° so that the gripper 730 is set downwards, and the gripper 730 swings open to release the product 20 onto the conveyor and into the next process. After that, all parts are reset and ready for the next operation.
