Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag production technology, and in particular to an automatic testing and clamping device for filter bag heads. Background Technology

[0002] In the dust collector filter bag manufacturing industry, to facilitate large-scale production and inspection, filter bags are typically produced in three parts: the bag head, the bag body, and the bag tail. For the bag head, the main inspection is whether it fits tightly against the tube sheet, which is crucial for the stable operation of the entire dust collector. To ensure the tightness of the bag heads in actual production, a tightness test is conducted on each bag head within the corresponding hole in the tube sheet during the inspection process, discarding defective products.

[0003] Currently, the inspection method for filter bag heads involves manually pressing and clamping the template plate. After passing inspection, the template plate is manually pressed open again, and the filter bag head is repeatedly disassembled and replaced for further inspection. Alternatively, the filter bag head is placed in a circular hole of a simulated template plate, and manually pressed to clamp it in place. The filter bag head is then tested to see if it can remain clamped in the hole for a certain period (e.g., 30 seconds), observing the clamping condition and testing whether it can maintain the clamping position or fall off within that time. On the one hand, this method requires manual, repetitive work, with testing personnel needing to install, clamp, and disassemble the filter bag heads, resulting in high labor intensity. On the other hand, due to limited human energy, the inspection efficiency is low, affecting the large-scale production of filter bag head components. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic testing and clamping device for filter bag heads, which can automatically complete the clamping test of filter bag heads, reduce manual labor intensity, and improve production efficiency.

[0005] To achieve the above objectives, the solution of this utility model is: An automatic testing and clamping device for filter bag heads includes a gripping unit, a calibration unit, a pressing unit, a bonding unit, and an automatic control unit. The gripping unit includes a liftable gripper mounted on a first mounting frame, which grips the bag head; The calibration unit includes a metal plate located below the first mounting bracket. The metal plate has a circular through hole forming a perforated plate hole into which the bag head can be inserted. The metal plate is formed by combining an upper part and a lower part. The upper part is movably connected above the lower part and is separated or merged with the lower part by an opening and closing component. The gripper is located above the metal plate and can drive the bag head into the opened perforated plate hole. The pressing unit includes a sliding seat located on one side of the calibration unit, and the sliding seat has a mounting shaft corresponding to the center position of the hole in the flower plate. The bonding unit includes a rotating shaft rotatably connected to the mounting shaft. Below the rotating shaft is a lifting clamping robot. After descending, the clamping robot is located at the outer periphery of the perforated plate hole and grips both sides of the metal plate. At the same time, the clamping robot presses the bag head, which is clamped in the perforated plate hole, into the perforated plate hole. Driven by the rotating shaft, the clamping robot rotates around the perforated plate hole once.

[0006] Furthermore, the first mounting frame is equipped with a first driving component that can drive the gripper to lift and lower. The opening and closing assembly is opened and closed by the second driving component. The sliding seat is moved forward to the hole in the tube sheet or backward by the third driving component. The clamping manipulator is lifted and lowered by the fourth driving component. The rotating shaft is rotated by the fifth driving component.

[0007] Furthermore, the calibration unit is equipped with an optical sensor that can detect whether the bag head has fallen out of the hole in the perforated plate; the pressing unit is equipped with an infrared rangefinder that can detect whether the sliding seat has slid into place; and the bonding unit is equipped with a camera sensor that detects whether the clamping robot has gripped the bag in place and a pressure sensor that detects whether the clamping robot has gripped the bag tightly. The optical sensor, infrared rangefinder, camera sensor, and pressure sensor transmit the collected signals to the automatic control unit.

[0008] Furthermore, it also includes a transport unit, which includes a transport track, a second mounting frame, and a storage frame for placing bag heads. The gripper is raised in the first mounting frame and connected to the transport track. The other end of the transport track is mounted on the second mounting frame. The gripper is liftable and mounted on the second mounting frame. The storage tray is located at the bottom of the second mounting frame.

[0009] Furthermore, the first driving component is a first motor. The gripper uses the first motor to drive a gear rack, belt, or chain to slide and lift between the first mounting frame, the conveying track, and the second mounting frame. The first motor is connected to the automatic control unit.

[0010] Furthermore, the pressing unit also includes a base, with a metal plate located on one side of the base. The base is provided with a slide rail for the sliding seat to slide on, and the slide rail is located outside the diameter of the hole in the perforated plate.

[0011] Furthermore, the metal plate is formed into a square plate, with the perforated hole located in the middle of the metal plate, and the upper and lower parts respectively passing through semi-circular through holes formed in a rectangular plate.

[0012] With the above structure, the automatic testing and clamping device for the filter bag head of this utility model can transform the previous manual testing into automated testing, which improves testing efficiency while ensuring testing quality, facilitates production, reduces testing time, reduces manual labor intensity, and improves product quality and production efficiency.

Detailed Implementation

[0014] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0015] Combination Figure 1 , Figure 2 As shown, this utility model discloses an automatic testing and clamping device for filter bag heads, including a gripping unit A, a calibration unit B, a pressing unit C, a bonding unit D, and an automatic control unit.

[0016] The gripping unit A includes a liftable gripper 12 mounted on the first mounting frame 11. The gripper 12 is used to grip the bag head (not shown in the figure).

[0017] The calibration unit B includes a metal plate 2 located below the first mounting bracket 11. The metal plate 2 has a circular through-hole forming a perforated hole 23 for inserting a bag head. The metal plate 2 is formed by combining an upper part 21 and a lower part 22. The upper part 21 is movably connected above the lower part 22 and can be separated or joined relative to the lower part 22 via an opening / closing assembly (not shown). The gripper 12 is located above the metal plate 2 and can guide the bag head into the opened perforated hole 23. In this embodiment, the metal plate 2 is a square plate, with the perforated hole 23 located in the middle. The upper part 21 and lower part 22 each have semi-circular through-holes formed in a rectangular plate. The upper part 21 can be flipped backward by the opening / closing assembly, allowing the bag head on the gripper to first be inserted into the semi-circular through-hole of the lower part 22, and then the upper part 21 can be flipped upward and combined with the lower part 22 to form a whole. Alternatively, the upper part 21 can also be flipped open to the sides, creating clearance space within the first mounting bracket 11.

[0018] The pressing unit C includes a slidable sliding seat 31 located on one side of the calibration unit B. The sliding seat 31 has a mounting shaft 32 corresponding to the center position of the perforated plate hole 23, so that the mounting height of the first mounting shaft 32 corresponds to the center position of the perforated plate hole. In this embodiment, the pressing unit C also includes a base 33, with a metal plate 2 located on one side of the base 33. The base 33 has a slide rail 34 for the sliding seat 31 to slide on, and the slide rail 34 is located outside the diameter of the perforated plate hole 23.

[0019] The bonding unit D includes a rotating shaft 41 rotatably connected to the mounting shaft 32. Below the rotating shaft 41 is a liftable clamping robot 42. After descending, the clamping robot 42 can be positioned at the outer periphery of the perforated plate hole 23 and grip both sides of the metal plate 2. The clamping robot 42 has claws 421 on both sides that respectively abut against the sides of the metal plate. Figure 2 As shown. At the same time, the clamping robot 42 also presses the bag head (not shown in the figure) that is clamped in the perforated plate hole 23 into the perforated plate hole 23. The clamping robot 42 presses the bag head against the inner ring surface of the perforated plate hole 23. Driven by the rotating shaft 41, the clamping robot 42 can rotate around the perforated plate hole 23 for one revolution, thereby realizing the clamping action of the bag head in the perforated plate hole 23.

[0020] During operation, the first mounting frame 11 is equipped with a first driving component that can drive the gripper 12 to rise and fall. The opening and closing assembly is opened and closed by the second driving component. The sliding seat 31 is moved forward to the hole 23 in the tube sheet or moved backward by the third driving component. The clamping manipulator 42 is raised and lowered by the fourth driving component. The rotating shaft 41 is rotated by the fifth driving component. The automatic control unit can control the operation of the first driving component, the second driving component, the third driving component, the fourth driving component and the fifth driving component, thereby realizing the orderly operation of each unit.

[0021] Furthermore, an optical sensor (not shown in the figure) can be installed in calibration unit B to detect whether the bag head has fallen out of the perforated plate hole 23, thereby determining whether the bag head has passed inspection. An infrared rangefinder (not shown in the figure) can be installed in pressing unit C to detect whether the sliding seat 31 has slid into place, preventing misalignment. A camera sensor (not shown in the figure) and a pressure sensor (not shown in the figure) can be installed in bonding unit D to detect whether the clamping robot 42 has gripped the bag head in place, preventing incomplete gripping and bonding of the bag head. The optical sensor, infrared rangefinder, camera sensor, and pressure sensor transmit the collected signals to the automatic control unit.

[0022] This device also includes a transport unit E, which comprises a conveyor track 51, a second mounting frame 52, and a storage frame 53 for placing bag heads. A gripper 12 can be raised from the first mounting frame 11 and connected to the conveyor track 51. The other end of the conveyor track 51 is mounted on the second mounting frame 52. The gripper 12 is also liftable and height-adjustable on the second mounting frame 52, enabling continuous movement of the gripper. The storage tray 53 is located at the bottom of the second mounting frame 52. In the gripping unit, the first driving component can be a first motor. The gripper 12 can slide and rise between the first mounting frame 11, the conveyor track 51, and the second mounting frame 52 by driving a gear rack, belt, or chain, etc., with the first motor. The first motor is connected to an automatic control unit. Through the transport unit E, the bag head can be removed from the storage frame 53 containing the bag head by the gripper, and then moved above the calibration unit A after passing through the second mounting frame 52, the conveyor track 51, and the first mounting frame 11, achieving automatic feeding.

[0023] In this invention, the automatic testing and clamping device for filter bag heads allows the bag head to be removed from the storage basket 53 via the gripper 12 during bag head testing. The bag head then passes through the second mounting frame 52, the conveying track 51, and the first mounting frame 11 before moving to the top of the calibration unit A. At this time, the upper part 21 of the metal plate 2 opens under the action of the opening and closing assembly, allowing the bag head to be inserted into the perforated plate hole 23 under the action of the gripper 12 (a sensor can also be installed here). The gripper then returns to its original position to grab the next bag head, and the upper part 21 merges with the lower part 22, securing the bag head in the perforated plate hole 23 of the metal plate 2. Then, the sliding seat 31 of the pressing unit drives the bonding unit to slide to the perforated plate hole 23, and the clamping manipulator 42 descends and grips both sides of the metal plate 2. The bag head (not shown in the figure) is pressed into the perforated plate hole 23. The clamping robot 42 presses the bag head onto the inner ring surface of the perforated plate hole 23. Driven by the rotating shaft 41, the clamping robot 42 can rotate around the perforated plate hole 23 for one revolution. After one revolution, the clamping robot 42 returns to its original position, thus realizing the clamping action of the bag head in the perforated plate hole 23. Finally, wait for a certain period of time and observe whether the bag head in the perforated plate hole will fall directly out of the perforated plate hole. If it falls out within the specified time, the clamping tightness is poor and the defective product is removed manually. If it does not fall out, the clamping test is completed. Alternatively, the bag head after the test can be removed manually to complete one bag head clamping test. Then the gripper in the clamping device can start the gripping operation to carry out the next bag head test.

[0024] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
