Description

Technical Field

[0001] This utility model relates to the field of production operation technology, and in particular to a pressing device that can be used on both sides. Background Technology

[0002] Screw tightening is a common and important assembly process in manufacturing. To ensure the accuracy of screw tightening and to prevent stripping or damage to the workpiece, the workpiece must remain stable during the operation, without displacement or bouncing. Therefore, using clamping equipment to reliably clamp the workpiece onto the worktable or positioning fixture before and during screw tightening is a crucial preliminary step.

[0003] However, in actual production, it has been found that many workpieces, due to functional requirements, often have different shapes, structures, or screw locations on their front and back sides. This asymmetry leads to a significant technical problem: traditional clamping solutions require a dedicated front clamping device for the front of the workpiece and another dedicated back clamping device for the back. These two devices are often designed and installed independently. On the one hand, two independent clamping devices require more installation space, making the entire workbench or automation unit layout bulky and hindering the compact design of the production line; on the other hand, the numerous components in the two independent clamping devices increase equipment costs.

[0004] Therefore, this utility model is dedicated to developing a double-sided pressing device that can effectively integrate the pressing functions of both sides, thereby improving the structural compactness and reducing manufacturing costs.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a double-sided pressing device that can effectively integrate the pressing functions of both sides, thereby improving structural compactness and reducing manufacturing costs.

[0007] To achieve the above objectives, this utility model provides a double-sided pressing device, comprising:

[0008] Two spaced-apart conveyor devices are used to transport workpieces;

[0009] A lifting mechanism, located between the two conveying devices, is used to lift the workpiece upwards;

[0010] Two sliding base plates are provided in one-to-one correspondence with the two conveying devices, and the sliding base plates are slidably connected to the corresponding conveying device along the feeding direction of the conveying device;

[0011] A front pressing module is mounted on the sliding base plate and is used to cooperate with the lifting mechanism to press the front of the workpiece downward.

[0012] A reverse pressing module is mounted on the sliding base plate and arranged along the feeding direction of the conveying device with the sliding base plate. It is used to cooperate with the lifting mechanism to press the reverse side of the workpiece downward.

[0013] A shifting direct drive mechanism, the drive end of which is connected to the sliding base plate, is used to drive the sliding base plate to slide back and forth, so that the front pressing module or the back pressing module moves to directly above the lifting mechanism.

[0014] Optionally, the conveying device is a conveyor belt or a set of conveyor rollers.

[0015] Optionally, both of the clamping modules include:

[0016] The pressure plate assembly is located above the two conveying devices;

[0017] A pressure plate direct drive mechanism, wherein the drive end of the pressure plate direct drive mechanism is connected to the pressure plate assembly, driving the pressure plate assembly to move up and down;

[0018] The shape of the front pressing module is adapted to the front of the workpiece, and the shape of the back pressing module is adapted to the back of the workpiece.

[0019] Optionally, the pressure plate direct drive mechanism of both clamping modules is mounted and fixed on the corresponding sliding base plate.

[0020] Optionally, the sliding base plate is provided with a connecting plate that protrudes outward to the drive end of the displacement direct drive mechanism at the middle position;

[0021] The two clamping modules are symmetrically arranged about the connecting plate.

[0022] Optionally, a light-blocking plate is installed on the connecting plate;

[0023] The double-sided clamping device also includes a positive pressure photoelectric sensor and a negative pressure photoelectric sensor for detecting the position of the light-blocking sheet;

[0024] Among them, the two photoelectric sensors are arranged along the feeding direction of the conveying device, and:

[0025] When the light-blocking plate blocks the positive pressure photoelectric sensor, the front pressing module is located directly above the lifting mechanism;

[0026] When the light-blocking plate blocks the reverse pressure photoelectric sensor, the reverse pressing module is located directly above the lifting mechanism.

[0027] Optionally, the pressure plate assembly is slidably connected to the sliding base plate via a vertical slider guide assembly.

[0028] Optionally, the pressure plate assembly includes a pressure plate bracket connected to the pressure plate direct drive mechanism and the slider guide rail assembly, and a replaceable pressure plate body detachably mounted on the pressure plate bracket.

[0029] Optionally, the pressure plate bracket and the replaceable pressure plate body are bolted together or plugged in and pulled out in the horizontal direction.

[0030] The beneficial effects of this utility model are as follows: It provides a double-sided clamping device, in which the workpiece is fed into the clamping station (i.e., the location of the lifting mechanism) by two spaced-apart conveying devices. The lifting mechanism lifts the workpiece from bottom to top, causing the workpiece to detach from the conveying devices. The shifting direct drive mechanism drives the sliding base plate to slide along the feeding direction of the conveying devices, thereby moving the front or back clamping module mounted on the sliding base plate to directly above the lifting mechanism. Specifically:

[0031] If the workpiece in the clamping station is facing up, the front clamping module is driven to move directly above the lifting mechanism, and then the front clamping module presses down on the front of the workpiece.

[0032] If the workpiece in the clamping station is facing up, the reverse clamping module is driven to move directly above the lifting mechanism, and then the reverse clamping module presses down on the reverse side of the workpiece.

[0033] After clamping is completed, the lifting mechanism descends, and the workpiece is returned to the conveyor and sent out.

[0034] The present invention provides a double-sided clamping device that can be used on both sides of a workpiece. By switching the positions of the front clamping module and the back clamping module through a shifting direct drive mechanism, it realizes the clamping function of the same device on both sides of the workpiece. It integrates the front and back clamping devices, reduces the space occupied by the device, improves the structural compactness, and reduces the manufacturing cost. Attached Figure Description

[0057] See Figure 1 and Figure 2 This embodiment provides a double-sided pressing device, including:

[0058] Two spaced-apart conveying devices 1 are used to transport workpieces;

[0059] The lifting mechanism (located directly below the front pressing module 3a in the attached drawing, and obscured by the front pressing module 3a, so it is not shown) is located between the two conveying devices 1 and is used to lift the workpiece upward.

[0060] Two sliding base plates 2 are provided in a one-to-one correspondence with the two conveying devices 1, and the sliding base plates 2 are slidably connected to the corresponding conveying device 1 along the feeding direction of the conveying device 1;

[0061] A front pressing module 3a is mounted on the sliding base plate 2 and is used to cooperate with the lifting mechanism to press the front of the workpiece downward.

[0062] The reverse pressing module 3b is installed on the sliding base plate 2 and arranged with the sliding base plate 2 along the feeding direction of the conveying device 1, and is used to cooperate with the lifting mechanism to press the reverse side of the workpiece downward.

[0063] The shifting direct drive mechanism 4 is connected to the sliding base plate 2 at its drive end, and is used to drive the sliding base plate 2 to slide back and forth so that the front pressing module 3a or the back pressing module 3b moves to the top of the lifting mechanism.

[0064] The double-sided clamping device provided in this embodiment feeds the workpiece into the clamping station (i.e., the location of the lifting mechanism) via two spaced-apart conveying devices 1. The lifting mechanism lifts the workpiece from bottom to top, causing it to detach from the conveying devices 1. The shifting direct drive mechanism 4 drives the sliding base plate 2 to slide along the feeding direction of the conveying devices 1, thereby moving the front clamping module 3a or the back clamping module 3b mounted on the sliding base plate 2 directly above the lifting mechanism. Specifically:

[0065] If the workpiece in the clamping station is facing up, the front clamping module 3a is driven to move directly above the lifting mechanism, and then the front clamping module 3a presses down on the front of the workpiece.

[0066] If the workpiece in the clamping station is facing up, the reverse clamping module 3b is driven to move directly above the lifting mechanism, and then the reverse clamping module 3b presses down on the reverse side of the workpiece.

[0067] After the clamping is completed, the lifting mechanism descends, and the workpiece is returned to the conveyor device 1 and sent out.

[0068] Furthermore, the camera can identify the front and back of the workpiece, thereby automatically switching the clamping module or determining the required clamping module through a preset program.

[0069] (1) A camera is configured in front of the double-sided clamping device to acquire workpiece image information. After acquiring the workpiece image information, it can be determined whether the workpiece entering the double-sided clamping device is facing up or facing down. Then, the corresponding front clamping module 3a or the back clamping module 3b is automatically controlled to move to the top of the lifting mechanism, thereby realizing the clamping operation of the front or the back.

[0070] (2) Before the operation, the control device is set to front-side pressing, and the front-side pressing module 3a is used by default for the entire operation; or, the control device is set to back-side pressing, and the back-side pressing module 3b is used by default for the entire operation.

[0071] The double-sided clamping device provided in this embodiment switches the positions of the front clamping module 3a and the back clamping module 3b through the shifting direct drive mechanism 4, realizing the clamping function of the front and back sides of the workpiece by the same device. It integrates the front and back clamping devices, reduces the space occupied by the device, improves the structural compactness, and reduces the manufacturing cost.

[0072] Optionally, the conveying device 1 is a conveyor belt or a conveyor roller assembly. Conveyor belts or conveyor roller assemblies are common conveying methods, with simple and reliable structures, low cost, and easy maintenance and integration into automated production lines, ensuring the smoothness and stability of workpiece conveying.

[0073] In this embodiment, both clamping modules include:

[0074] The pressure plate assembly 301 is located above the two conveying devices 1;

[0075] The pressure plate direct drive mechanism 302 is connected to the pressure plate assembly 301 at its drive end, which drives the pressure plate assembly 301 to move up and down.

[0076] The shape of the front pressing module 3a is adapted to the front of the workpiece, and the shape of the back pressing module 3b is adapted to the back of the workpiece.

[0077] The direct drive mechanism 302 drives the pressure plate assembly 301 to move up and down, realizing the clamping and releasing actions. The direct drive mechanism 302 provides direct drive, fast response, and high control precision. The shape of the pressure plate assembly 301 is adapted to the surface of the workpiece, avoiding damage or displacement of the workpiece during the clamping process, thus improving the clamping quality and operational safety.

[0078] Optionally, the pressure plate direct drive mechanism 302 of both clamping modules is mounted and fixed on the corresponding sliding base plate 2. Further, a connecting plate 5 is provided at the middle position of the sliding base plate 2, protruding outward to the drive end of the shifting direct drive mechanism 4; wherein the two clamping modules are symmetrically arranged about the connecting plate 5.

[0079] The pressure plate direct drive mechanism 302 is fixed to the sliding base plate 2, allowing the clamping module to move as a whole. This ensures structural stability, reduces the risk of loosening of moving parts, and improves the rigidity and reliability of the equipment. When the shifting direct drive mechanism 4 drives the sliding base plate 2 to move, the two clamping modules interchange positions with the initial position of the connecting plate 5 as the center. The symmetrical design balances the forces on the equipment, reduces the risk of off-center loading and jamming during the movement of the sliding base plate 2, and improves the smoothness of movement and service life.

[0080] Optionally, a light-blocking plate 6 is installed on the connecting plate 5. The double-sided clamping device further includes a positive pressure photoelectric sensor 8 and a negative pressure photoelectric sensor 9 for detecting the position of the light-blocking plate 6;

[0081] The two photoelectric sensors are arranged along the feeding direction of the conveying device 1. When the sliding base plate 2 moves, the light-blocking plate 6 moves with the connecting plate 5.

[0082] When the light-blocking plate 6 blocks the positive pressure photoelectric sensor 8, the front pressing module 3a is located directly above the lifting mechanism;

[0083] When the light-blocking plate 6 blocks the reverse pressure photoelectric sensor 9, the reverse pressing module 3b is located directly above the lifting mechanism.

[0084] When the light-blocking plate 6 blocks the positive pressure photoelectric sensor 8, it indicates that the front pressing module 3a has moved directly above the lifting mechanism; when the light-blocking plate 6 blocks the reverse pressure photoelectric sensor 9, it indicates that the reverse pressing module 3b has moved directly above the lifting mechanism. The sensor signals are fed back to the control system for precise positioning.

[0085] Optionally, the pressure plate assembly 301 is slidably connected to the sliding base plate 2 via a vertical slider guide rail assembly 7. The slider guide rail assembly 7 provides high-precision guidance, ensuring smooth and stable movement of the pressure plate assembly 301 without wobbling, improving the stability and accuracy of the clamping, and reducing wear.

[0086] In this embodiment, the pressure plate assembly 301 includes a pressure plate bracket 3011 connected to the pressure plate direct drive mechanism 302 and the slider guide rail assembly 7, and a replaceable pressure plate body 3012 detachably mounted on the pressure plate bracket 3011. The pressure plate bracket 3011 serves as the basic structure, while the replaceable pressure plate body 3012 directly contacts the workpiece and can be replaced according to the workpiece shape. The replaceable pressure plate body 3012 design allows for quick replacement of the pressure plate according to the surface shape of different workpieces, improving the versatility and flexibility of the equipment and reducing changeover time and costs.

[0087] In this embodiment, the pressure plate bracket 3011 and the replaceable pressure plate body 3012 are locked together by multiple locking bolts or connected by a horizontal plug-in connection (for example, a horizontal slot with a side opening is provided in the pressure plate bracket 3011 for the horizontal insertion of the replaceable pressure plate body 3012, thereby achieving vertical limitation of the replaceable pressure plate body 3012, and then horizontal positioning is achieved by one or two positioning screws). The bolt locking connection is reliable and secure, and the plug-in connection is quick and convenient. Both methods facilitate the maintenance and replacement of the pressure plate, further improving the adaptability and operating efficiency of the equipment.

[0088] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
