Technical Field

[0001] The utility model relates to the technical field of mechanical clamps, in particular to a mechanical grasping device and an injection molding product production system. Background Art

[0002] Among the various types, there is a type of product with a special structure. This product has structural features such as grooves, raised ribs and holes. The adsorption surface is small and eccentric, and it is not suitable for discharging by adsorption.

[0003] The mold for this type of product has an ultra-small-pitch cavity arrangement, which is not suitable for direct clamping by a one-to-one cylinder clamp to discharge the material.

[0004] However, if the materials are unloaded by free fall, manual sorting is required, and the streamlined operation is inefficient.

[0005] Therefore, the three traditional discharging methods are not applicable to this type of product. Utility Model Content

[0006] In view of this, the utility model provides a mechanical grasping device and an injection molding product production system to solve the problem that the existing discharge method is not applicable due to the special product structure and the small mold cavity spacing.

[0008] Beneficial effects: The mechanical gripping device provided by the present invention clamps the product by setting a dovetail clamp assembly. The dovetail clamp can clamp the product from both sides of the product and is not restricted by the special structural features of the product.

The two pressure rods in the pressure rod assembly can be driven to move by the opening and closing drive assembly. When the two pressure rods move in one direction, they can squeeze the control section of the dovetail clamp, so that the opening and clamping action of the dovetail clamp can be achieved. When the opening and closing drive assembly drives the two pressure rods to move in the opposite direction, the control section of the dovetail clamp can be released, thereby closing the dovetail clamp. Thus, the opening and closing action of the dovetail clamp is achieved by driving the movement of the pressure rod by the opening and closing drive assembly, so that the product can be clamped or released, the material is discharged efficiently, and the process is safe and reliable.

[0013] In an optional embodiment, the telescopic block is a wedge-shaped structure, and the side surface of the telescopic block close to the wedge surface cooperates with the wedge surface.

[0014] In an optional embodiment, a limit plate is further included, which is arranged on the mounting seat and blocks the end of the slide groove away from the pressure rod.

[0015] In an optional embodiment, an angle flip mechanism is further included, which includes a docking seat and a flip plate. The first end of the flip plate is rotatably connected to the docking seat, and the second end of the flip plate is connected to the opening and closing drive assembly.

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0037] For a type of injection molded product with special structure, it has structural features such as grooves, raised ribs and holes, such as Figure 1 As shown. For the discharge of injection molded products of this type of structure, the following three discharge methods are conceived in the relevant technology:

[0038] 1. Use a suction cup fixture to absorb the product.

[0039] Due to the multiple ribs and holes on the surface of the product, the suction cup has a very small adsorption area. The maximum diameter of the suction cup can be 2 mm. The adsorption position is too eccentric and the adsorption force is insufficient. The risk of the product 10 falling during the transfer process is too high. Therefore, this technical solution is actually not feasible and cannot be applied to the mass production implementation plan of the mold.

[0040] 2. Use multiple cylinder clamps to clamp products one by one.

[0041] Specifically, the mold molds eight products 10 at a time, and eight cylinders are correspondingly provided to clamp the products one-on-one. Using the same number of cylinder clamps as the number of products 10 ejected from the mold to clamp the products 10 from both sides can address the surface characteristics of this product, which has multiple ribs and holes, and a small suction cup area. However, the vertical dimensions of the clamps produced by this vertical cylinder technology solution are too large, requiring a longer distance between the products in the mold and the distance between the front and back mold halves, exceeding the performance dimensions of the corresponding injection molding machine specifications. Similarly, this solution was eliminated.

[0042] 3. Use transfer boxes to collect free-fall products 10.

[0043] A transfer box is used to collect the free-falling products 10. There is no requirement for the number of mold cavity arrangements and the cavity spacing of the products 10. The products 10 are ejected from the mold, fall freely, and fall into a specific transfer box. They are then manually sorted and arranged and sent to the next work section. However, this solution cannot fully meet the needs of efficient streamlined automatic operations. In addition, there is a risk that products will splash onto the guide pillars of the front half of the mold (posing a risk of mold compression) or fall outside the transfer box (additional manual collection, dust removal / decontamination, and rejection of defective products are required), so it has not been implemented.

[0044] Due to the particularity of the product structure and its mold, the above three relatively conventional solutions cannot meet the needs of streamlined automatic operation. In particular, a mechanical gripping device is needed to solve the technical problems of automated streamlined removal of products 10 from injection molding molds with multiple cavities in one mold, appearance requirements, inability to collect products 10 by free fall, ultra-small cavity spacing, small size of products 10 and porous and / or multi-ribbed outer surfaces, so as to achieve the technical goals of efficient removal of products 10 and safe and reliable process.

[0045] The following combination Figures 1 to 13 , describing the embodiments of the present utility model.

[0046] According to an embodiment of the present invention, in one aspect, a mechanical grasping device 100 is provided, comprising a mounting base 1, a dovetail clamp assembly 2, a pressure rod assembly, and an opening and closing drive assembly 4. The dovetail clamp assembly 2 is mounted on the mounting base 1 and includes two hinged clips 201, each of which includes a control section 21 and a clamping section 22 located on either side of the hinge point. The pressure rod assembly includes two pressure rods 3, which are movably mounted on the mounting base 1 and are located on either side of the dovetail clamp assembly 2. The opening and closing drive assembly 4 is connected to the pressure rods 3 and is adapted to drive the pressure rods 3 to move back and forth along a path, thereby acting on the control section 21 to open the clamping section 22, or releasing the control section 21 to close the clamping section 22.

[0047] The mechanical grasping device 100 provided by the embodiment of the present invention is configured to clamp the product 10 by providing a dovetail clamp assembly 2. The dovetail clamp assembly 2 can clamp the product 10 from both sides of the product 10 and is not restricted by the special structural features of the product 10. Moreover, since the dovetail clamp assembly 2 occupies less space than a cylinder clamp, it can meet the requirements of molds with ultra-small cavity spacing. The opening and closing drive assembly 4 can drive the two pressure rods 3 in the pressure rod assembly to move. When the two pressure rods 3 move in one direction, they can squeeze the control section 21 of the dovetail clamp assembly 2, thereby realizing the opening and closing action of the dovetail clamp assembly 2. When the opening and closing drive assembly 4 drives the two pressure rods 3 to move in the opposite direction, it can release the control section 21 of the dovetail clamp assembly 2, thereby closing the dovetail clamp assembly 2. Thus, the opening and closing action of the dovetail clamp assembly 2 is realized by driving the movement of the pressure rods 3 by the opening and closing drive assembly 4, thereby clamping or releasing the product 10, achieving efficient discharge and a safe and reliable process.

[0048] Specifically, since the control section 21 and the clamping section 22 are respectively located on both sides of the hinge axis, the control section 21 and the clamping section 22 move in opposite directions around the hinge axis. When the spacing of the control sections 21 is reduced, the spacing of the clamping sections 22 is expanded, that is, the dovetail clamp assembly is in an open state; when the spacing of the control sections 21 is expanded, the spacing of the clamping sections 22 is reduced, that is, the dovetail clamp assembly is in a closed state.

[0049] The opening and closing of the clamping section 22 can be controlled by controlling the spacing of the control sections 21 of the two clips 201. In this embodiment, two compression rods 3 are used to squeeze and release the control sections 21, thereby covering the spacing of the control sections 21. The spacing between the two compression rods 3 is greater than the minimum spacing of the control sections 21, but less than the maximum spacing of the control sections 21. This allows the movement of the compression rods 3 to squeeze or release the control sections 21 without moving beyond the range of the control sections 21.

[0050] In some embodiments, the dovetail clamp assembly 2 further includes a torsion spring 202 and a rotating shaft 203 , the two clips 201 are rotatably connected to the rotating shaft 203 , the rotating shaft 203 is disposed on the mounting seat 1 , the torsion spring 202 is sleeved on the rotating shaft 203 and is compressed between the two clips 201 .

[0051] Specifically, both clips 201 are provided with axial holes, which are sleeved onto the rotating shaft 203, forming a dovetail shape. The hinge point of the dovetail clamp assembly 2 is the location of the rotating shaft 203, that is, the control section 21 and the clamping section 22 are located on either side of the rotating shaft 203. As the clamping sections 22 of the two clips 201 contract, the control sections 21 of the two clips 201 expand outward. Therefore, when the pressure rod 3 moves along the clamping section 22 toward the control section 21, it will first abut the control section 21. Continued movement will apply a compressive force to the control section 21, thereby causing the clamping section 22 to open.

[0052] Because the torsion spring 202 is compressed between the two clips 201, it applies an elastic force to the two clips 201, causing the two clips 201 to remain closed in the absence of other external forces. The aforementioned pressure rod assembly is disposed on both sides of the dovetail clamp assembly 2. When the pressure rod assembly squeezes the control section 21, it applies pressure to the two clips 201, overcoming the elastic force of the torsion spring 202 and causing the two clips 201 to open. The movement of the pressure rod assembly can change the pressure applied to the control section 21 until the pressure reaches zero, i.e., the control section 21 is released. At this point, the two clips 201 remain clamped to the product 10 or remain closed in the normal state under the elastic force of the torsion spring 202.

[0053] In some embodiments, the feet of the two clips 201 are attached with flexible strips 204, such as foam, on the inner sides facing each other. This can cooperate with the torsion spring 202 to ensure that the clamping force generated on each product 10 can achieve a good adaptive balance when clamping the product 10, and there will be no phenomenon that some products 10 cannot be clamped and fall. On the other hand, the flexible strip 204 is set in the area where the clip 201 contacts the product, which can prevent products with high-gloss surfaces from being pinched or scratched, thereby protecting the product 10.

[0054] In some embodiments, the mounting base 1 is provided with a guide hole 101 , and the pressure rod 3 is at least partially passed through the guide hole 101 . The pressure rod 3 is suitable for moving in the guide hole 101 .

[0055] Specifically, in this embodiment, the guide hole 101 of the mounting base 1 is in the shape of an elongated strip. The pressure rod 3 is at least partially disposed in the guide hole 101. Therefore, the shape and length of the guide hole 101 will limit the movement path and movable stroke of the pressure rod 3.

[0056] To simplify the structure, while ensuring that the clamp can be opened, the shorter the travel of the pressure rod 3, the smaller the space occupied. To this end, in some embodiments, the travel path of the pressure rod 3 is designed to be a straight line. The elongated hole is arranged perpendicular to the rotating axis 203 of the dovetail clamp assembly 2. In actual clamping operation, the elongated hole is arranged vertically.

[0057] by Figure 3 or Figure 5 From the perspective shown in the figure, in this embodiment, when the pressure rod 3 moves upward, the pressure of the pressure rod 3 on the control section 21 of the dovetail clamp assembly 2 gradually increases, and the opening of the clamping section 22 gradually increases. Figure 5 In the position shown, the opening of the clamping section 22 is the largest; on the contrary, when the pressure rod 3 moves downward, the pressure of the pressure rod 3 on the control section 21 of the dovetail clamp assembly 2 gradually decreases, and the opening of the clamping section 22 gradually decreases. Figure 3In the position shown, the pressure rod 3 completely releases the control section 21, the control section 21 is not subjected to the extrusion force, and the opening of the clamping section 22 remains closed or clamps the product 10 under the action of the torsion spring 202.

[0058] In some embodiments, the mounting base 1 is provided with a slide groove 102 ; the opening and closing driving assembly 4 includes a slide 401 , the slide 401 is slidably provided in the slide groove 102 , and the pressure rod 3 is provided on the slide 401 .

[0059] Because the mounting base 1 is provided with a slide groove 102, the slide 401 of the opening and closing drive assembly 4 can slide within the slide groove 102, which acts as a limiter for the movement of the slide 401. The pressure rod 3 is mounted on the slide 401. Therefore, the position of the slide 401 by the slide groove 102 can control the movement path of the pressure rod 3. Because the pressure rod 3 is limited by the guide hole 101, the sliding path of the slide 401 and the movement path of the pressure rod 3 are parallel. In this embodiment, the movement paths of the slide 401 and the pressure rod 3 are both vertical.

[0060] In some embodiments, the slide 401 is provided with a driving cavity 402, and the inner end surface of the driving cavity 402 away from the pressure rod 3 is set as a wedge surface 4021; the opening and closing drive assembly 4 also includes a telescopic block 403, and the telescopic block 403 is suitable for entering and exiting the driving cavity 402; the telescopic block 403 is suitable for abutting against the wedge surface 4021, and the movement of the telescopic block 403 relative to the wedge surface 4021 is suitable for driving the slide 401 to slide up and down in the slide groove 102.

[0061] Since the telescopic block 403 can be extended and retracted, the telescopic block 403 can enter the drive cavity 402 when extended, and can leave the drive cavity 402 when retracted. The position of the telescopic block 403 in the drive cavity 402 is different depending on the distance of extension or contraction of the telescopic block 403. The inner end surface of the drive cavity 402 away from the pressure rod 3 is set as a wedge surface 4021. Figure 4 or Figure 6 In the figure, the inner end surface of the upper portion of the driving cavity 402 is a wedge-shaped surface 4021, and the telescopic block 403 contacts the wedge-shaped surface 4021. The telescopic block 403 changes the contact position of the telescopic block 403 with the wedge-shaped surface 4021 by controlling the extended length, thereby driving the slide 401 to move up and down. The pressure rod 3 is provided on the slide 401, thus being able to drive the pressure rod 3 to move up and down. When the extended length of the telescopic block 403 is small, such as Figure 4 As shown, the telescopic block 403 squeezes the wedge surface 4021 of the driving cavity 402, the distance that the slide 401 is squeezed and lifted is small, the pressure rod 3 is in a low position, the pressure on the control section 21 of the dovetail clamp assembly 2 is small, and the opening of the clamping section 22 is small; when the telescopic block 403 is extended to a large length, as shown Figure 6As shown, the telescopic block 403 squeezes the wedge-shaped surface 4021 of the drive cavity 402. The greater the distance the slide 401 is squeezed and lifted, the higher the pressure rod 3 is, the greater the pressure on the control section 21 of the dovetail clamp assembly 2 is, and the larger the opening of the clamping section 22 is. That is, when the clamp needs to be opened, the telescopic block 403 extends, squeezing the wedge-shaped surface 4021 of the drive cavity 402, lifting the slide 401, and the slide 401 drives the pressure rod 3 upward, which squeezes the control section 21 of the dovetail clamp assembly 2 to achieve opening. When clamping or closing is required, the telescopic block 403 shortens, the slide 401 gradually drops, and the slide 401 drives the pressure rod 3 downward. The pressure of the pressure rod 3 on the control section 21 of the dovetail clamp assembly 2 gradually decreases until it is released, and the clamping section 22 of the dovetail clamp assembly 2 closes or clamps the product 10.

[0062] In some embodiments, the telescopic block 403 is a wedge-shaped structure, and the side surface of the telescopic block 403 close to the wedge surface 4021 cooperates with the wedge surface 4021 .

[0063] Since the telescopic block 403 lifts or lowers the slide 401 by contacting and squeezing the wedge surface 4021 of the driving cavity 402, the side of the telescopic block 403 close to the wedge surface 4021 is set as an inclined surface, which can cooperate with the wedge surface 4021 of the driving cavity 402, so that the contact area between the telescopic block 403 and the wedge surface 4021 of the driving cavity 402 is increased during the telescopic process, thereby increasing the stability and reliability of the movement of the slide 401.

[0064] In one embodiment, the driving cavity 402 is provided with openings on both sides of the wedge surface 4021, and the telescopic block 403 can enter the driving cavity 402 from the entrance and extend from the opening on the opposite side of the driving cavity 402. This ensures that the telescopic block 403 has a sufficient extension distance, thereby ensuring that the movement stroke of the slide 401 and the pressure rod 3 thereon is sufficient, and ensuring the opening degree of the clamping section 22 of the dovetail clamp assembly 2 to accommodate products 10 of various sizes.

[0065] In some embodiments, a limiting plate 5 is further included. The limiting plate 5 is provided on the mounting seat 1 and blocks the end of the sliding groove 102 away from the pressure rod 3 .

[0066] By setting a limit plate 5 on the mounting base 1, the limit plate 5 can block the end of the slide groove 102 away from the pressure rod 3. Figure 4 or Figure 6 In the figure, it is shown as the upper end of the chute 102. Like this, it is possible to avoid that the wedge-shaped surface 4021 of the slide 401 is disengaged from the telescopic block 403 because the telescopic block 403 extends out a large distance and lifts the slide 401.

[0067] Furthermore, the limiting plate 5 is provided with a limiting groove 501, which cooperates with the top of the slide 401. The groove wall of the limiting groove 501 can limit the slide 401, prevent the slide 401 from slipping with the telescopic block 403, and improve the reliability of the structure.

[0068] Specifically, in some embodiments, the telescopic block 403 is connected to a telescopic driving member 404. Specifically, in this embodiment, the telescopic driving member 404 is a cylinder.

[0069] In some embodiments, two dovetail clamp assemblies 2 are arranged side by side along the axial direction of the pressure rod 3, and the two dovetail clamp assemblies 2 are arranged on both sides of the mounting base 1. The pressure rod 3 passes through the guide hole 101, and the two ends of the pressure rod 3 extend to the control sections 21 of the dovetail clamp assemblies 2 on both sides respectively.

[0070] Along the axial direction of the pressure rod 3, two dovetail clamp assemblies 2 are arranged in parallel. The movement of the telescopic block 403 is driven by a driving member, which can drive the pressure rod 3 to move up and down. The two pressure rods 3 are coordinated as a group to realize the simultaneous opening and clamping of the two dovetail clamp assemblies 2. Therefore, it is possible to clamp two products 10 at the same time. The structure is compact and meets the discharge requirements of the mold product 10 with ultra-small spacing cavity.

[0071] In some embodiments, along the radial direction of the pressure rod 3 , at least two dovetail clamp assemblies 2 are arranged in parallel on the same side of the mounting seat 1 , and the number of the pressure rod assemblies and the dovetail clamp assemblies 2 are arranged correspondingly.

[0072] At least two dovetail clamp assemblies 2 are arranged in parallel along the radial direction of the pressure rod 3. In this way, by driving the telescopic block 403 to extend and retract through a driving member, multiple dovetail clamp assemblies 2 can be opened and clamped for products 10 at the same time, realizing automatic and efficient discharge.

[0073] exist Figure 2 In the illustrated embodiment, one mechanical gripping device 100 is provided with four dovetail clamp assemblies 2 , that is, the movement of one telescopic block 403 can enable the four dovetail clamp assemblies 2 to simultaneously open and clamp the product 10 .

[0074] In some embodiments, an angle flip mechanism 6 is also included. The angle flip mechanism 6 includes a docking seat 601 and a flip plate 602. The first end of the flip plate 602 is rotatably connected to the docking seat 601, and the second end of the flip plate 602 is connected to the opening and closing drive assembly 4.

[0075] Because the first end of the flip plate 602 is rotatably connected to the docking seat 601, the flip plate 602 can flip relative to the docking seat 601. Furthermore, because the second end of the flip plate 602 is connected to the opening and closing drive assembly 4, the opening and closing drive assembly 4 can flip along with the flip plate 602. Therefore, by providing the angle flipping mechanism 6, after clamping the product 10, the product 10 can be flipped to a certain angle based on the placement requirements of the product 10 in the next process step. Specifically, the second end of the flip plate 602 is connected to the telescopic drive member 404 of the opening and closing drive assembly 4.

[0076] In some embodiments, the angle flipping mechanism 6 also includes a flipping drive 603 and a swing arm 604. The flipping drive 603 is arranged on the docking seat 601. The first end of the swing arm 604 is rotatably connected to the flipping drive 603, and the second end of the swing arm 604 is rotatably connected to the second end of the flip plate 602.

[0077] Because the first end of the swing arm 604 is rotatably connected to the flip driver 603, the swing arm 604 can swing relative to the flip driver 603. The second end of the swing arm 604 is rotatably connected to the second end of the flip plate 602, allowing the swing arm 604 to swing relative to the flip plate 602. The swing arm 604 is positioned between the flip driver 603 and the flip plate 602, acting as a connecting rod. The flip driver 603 outputs power, causing the swing arm 604 to pull the flip plate 602 relative to the docking station 601, thereby causing the mounting station 1 to flip, causing the product 10 held by the dovetail clamp assembly 2 on the mounting station 1 to flip to a certain angle.

[0078] In some embodiments, the flip plate 602 includes a first plate body and a second plate body, the first plate body and the second plate body are arranged vertically. The first plate body is rotatably connected to the docking seat 601, and the second plate body is rotatably connected to the swing arm 604.

[0079] In some embodiments, the flip driver 603 comprises a pneumatic cylinder.

[0080] In some embodiments, the angle between the direction in which the injection molded product is ejected from the mold cavity and the direction in which the product is placed at the next streamlined workstation is 90°. Therefore, taking the implementation of a 0° to 90° angle flip as an example, when the piston rod of the flip driving member 603 is in an extended state, such as Figure 9 As shown, the clamped product 10 is in the original discharge state and is flipped at an angle of 0°.

[0081] When the piston rod of the flip driving member 603 is retracted a certain distance, as shown in FIG. Figure 10 As shown, the piston rod pulls the flip plate 602 to flip to a certain angle through the swing arm 604. Figure 10 In the figure, the clamped product 10 is turned clockwise at a certain angle.

[0082] When the piston rod of the flip driving member 603 is fully retracted, as shown in FIG. Figure 11 As shown, the piston rod pulls the flip plate 602 to flip to the maximum angle through the swing arm 604. Figure 11 The clamped product 10 is shown to be turned 90° clockwise.

[0083] On the contrary, when the piston rod of the flip driving member 603 is extended, it can push the flip plate 602 to flip in the opposite direction through the swing arm 604. Figures 9 to 11 It is shown as flipping in the counterclockwise direction.

[0084] Of course, the flipping angle of the angle flipping mechanism 6 is determined according to actual needs and is not limited here.

[0085] According to an embodiment of the present invention, on the other hand, a system for producing injection molded products is provided, comprising the mechanical gripping device 100 according to any one of the above embodiments.

[0086] Furthermore, the injection molding product production system further comprises an injection mold 200, which is used to produce injection molded products. The mechanical gripping device 100 is used to grip the injection molded products.

[0087] Because the injection molding product production system includes the mechanical grasping device 100 and has the same effect as the mechanical grasping device 100 , it will not be described in detail here.

[0088] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
