Description

Technical Field

[0001] This utility model relates to the field of material strip clamping technology, and in particular to a precision clamping mechanism for continuous material strip movement. Background Technology

[0002] In today's highly automated industrial production, especially in precision manufacturing industries such as electronics manufacturing and semiconductor processing, continuous, stable and precise tape delivery and clamping technology is crucial to ensure that the tape carrying the chips is accurately delivered to each workstation for processing and testing.

[0003] The existing precision clamping mechanism for continuous material belt movement typically consists of a clamping part and a transmission part. The clamping part clamps the material belt, while the transmission part drives the clamping part and the material belt to move continuously, thereby realizing continuous material belt conveying. During the conveying process, the clamping part always maintains the clamping state of the material belt to ensure the stability of the material belt position.

[0004] However, in existing technologies, the clamping structure is exposed to the external environment, and its surface will inevitably be covered with dust, debris and other impurities. Since most existing clamping mechanisms only focus on clamping and conveying functions and neglect dust removal requirements, the impurities attached to the conveying part are very likely to rub against the conveying belt during the material belt clamping and conveying process, causing scratches on the surface of the belt, which will affect the accuracy of the subsequent test results. Utility Model Content

[0005] To overcome the problem that most existing clamping mechanisms only focus on clamping and conveying functions and neglect dust removal requirements, which leads to impurities attached to the conveying part easily rubbing against the conveying belt during the material belt clamping and conveying process, causing scratches on the belt surface, and thus affecting the accuracy of subsequent test results.

[0006] The technical solution of this utility model is: a precision clamping mechanism for continuous movement of a material strip, comprising,

[0007] A conveying assembly, a clamping assembly disposed on the top of the conveying assembly, and a dust removal assembly disposed on the surface of the clamping assembly;

[0008] The dust removal assembly includes a connecting box, a conveying pipe connected to the top of the connecting box, a suction pipe connected to the other end of the conveying pipe, a centrifugal fan fixedly connected to the bottom of the connecting box and whose air inlet is connected to the connecting box, a connecting pipe connected to the air outlet of the centrifugal fan, a spray pipe connected to the other end of the connecting pipe, and a metal filter and a HEPA filter disposed at the upper and lower ends of the inner cavity of the connecting box.

[0009] Preferably, the clamping assembly can clamp the material strip, and the conveying assembly can continuously convey the clamping assembly and the material strip, thereby ensuring that the material strip can be continuously and stably conveyed to each workstation for inspection or processing. During the conveying process, the centrifugal fan is turned on, which can create negative pressure in the connecting box. External dusty air enters the connecting box through the suction pipe and the conveying pipe. It first passes through the metal filter for preliminary filtration to remove larger particulate impurities, and then passes through the HEPA filter for further filtration of fine particles. The filtered clean air reaches the nozzle through the connecting pipe and is finally sprayed out from the nozzle. The airflow from the nozzle, combined with the suction of the suction pipe, achieves air convection, allowing dust in the surrounding environment to be quickly sucked up by the suction pipe, thereby purifying the surrounding air and preventing impurities from adhering and causing friction and scratches between the material strip and the adhering impurities during the conveying process. This ensures the surface quality of the material strip and provides a reliable foundation for subsequent chip processing and inspection.

[0010] Preferably, the conveying assembly includes a bracket, a first geared motor fixedly connected to the bottom of the inner cavity of the bracket, a screw connected to the output shaft of the first geared motor, a threaded sleeve threaded to the surface of the screw, and a connecting frame fixedly connected to the top of the threaded sleeve.

[0011] Preferably, the clamping assembly includes a movable frame movably connected to the front and rear ends of the top of the connecting frame, a toothed plate fixedly connected to the bottom of the movable frame, a clamping plate fixedly connected to one side of the movable frame, a rubber pad fixedly connected to one side of the clamping plate, a second reduction motor fixedly connected to the top of the inner cavity of the connecting frame, and a gear drivenly connected to the output shaft of the second reduction motor and meshing with the toothed plate.

[0012] Preferably, the front and rear ends of the bottom of the connecting frame are fixedly connected to a first sliding sleeve, and the front and rear ends of the bottom of the inner cavity of the bracket are fixedly connected to a first guide rail. The first sliding sleeve is sleeved on the surface of the first guide rail and is slidably connected to the surface of the first guide rail.

[0013] Preferably, the top two sides of the connecting frame are fixedly connected to a second guide rail, and the bottom two sides of the movable frame are fixedly connected to a second sliding sleeve. The second sliding sleeve is sleeved on the surface of the second guide rail and is slidably connected to the surface of the second guide rail.

[0014] Preferably, the top of the bracket is movably connected to a sliding roller via a bearing, and supports are provided around the bottom of the bracket.

[0015] Preferably, one side of the connecting box is fixedly connected to the front of the front movable frame, the bottom of the suction pipe is fixedly connected to the top of the front movable frame, and the bottom of the spray pipe is fixedly connected to the top of the rear movable frame.

[0016] The beneficial effects of this utility model are as follows: The clamping component can clamp the material strip, and the conveying component can realize the continuous conveying of the clamping component and the material strip, thereby ensuring that the material strip can be continuously and stably conveyed to various workstations for testing or processing. During the conveying process, a centrifugal fan creates negative pressure in the connecting box, which then draws dusty air from around the clamping component into the connecting box through the suction pipe and the conveying pipe. The air is then filtered through a metal filter and a HEPA filter, and the clean air is then conveyed to the nozzle through the connecting pipe and sprayed out. The airflow from the nozzle, combined with the suction from the suction pipe, achieves air convection, which can quickly remove surrounding dust and impurities, ensuring the cleanliness of the environment during the clamping and conveying process. This effectively prevents the material strip from being scratched by friction with attached impurities during the conveying process, thereby ensuring the surface quality of the material strip and providing a reliable foundation for subsequent chip processing and testing.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] Please see Figures 1-5 This utility model provides an embodiment of a precision clamping mechanism for continuous material belt movement, comprising a conveying assembly 100, which includes a bracket 110, a first reduction motor 120 fixedly connected to the bottom of the inner cavity of the bracket 110, a screw 130 drivenly connected to the output shaft of the first reduction motor 120, a threaded sleeve 140 threadedly connected to the surface of the screw 130, and a connecting frame 150 fixedly connected to the top of the threaded sleeve 140. A clamping assembly 200 is disposed on the top of the conveying assembly 100, comprising a movable frame 210 movably connected to the front and rear ends of the top of the connecting frame 150, a toothed plate 240 fixedly connected to the bottom of the movable frame 210, a clamping plate 220 fixedly connected to one side of the movable frame 210, and a rubber pad fixedly connected to one side of the clamping plate 220. 230, a second geared motor 250 fixedly connected to the top of the inner cavity of the connecting frame 150, a gear 260 connected to the output shaft of the second geared motor 250 and meshing with the gear plate 240, and a dust removal assembly 300 disposed on the surface of the clamping assembly 200; the dust removal assembly 300 includes a connecting box 310, a conveying pipe 330 connected to the top of the connecting box 310, a suction pipe 320 connected to the other end of the conveying pipe 330, a centrifugal fan 340 fixedly connected to the bottom of the connecting box 310 and having its air inlet end connected to the connecting box 310, a connecting pipe 350 connected to the air outlet end of the centrifugal fan 340, a spray pipe 360 ​​connected to the other end of the connecting pipe 350, and a metal filter screen 370 and a HEPA filter screen 380 disposed at the upper and lower ends of the inner cavity of the connecting box 310.

[0026] During operation, the strip carrying the chip is first placed on the sliding roller 111 at the top of the bracket 110. The position of the strip is manually adjusted to the desired conveying position. Then, the second reduction motor 250 in the clamping assembly 200 is started. The second reduction motor 250 operates, and its output shaft drives the gear 260 to rotate. The gear 260 meshes with the toothed plate 240, thereby converting rotational force into linear motion force. Through the toothed plate 240, the movable frame 210 and the clamping plate 220 are moved, causing the chip on the clamping plate 220 to move. The rubber pad 230 contacts the material belt to clamp it. By controlling the rotation direction and angle of the second reduction motor 250, the clamping force and position of the clamping plate 220 can be adjusted. Then, the first reduction motor 120 in the conveying assembly 100 is started. After the first reduction motor 120 starts, its output shaft drives the screw 130 to rotate. Since the screw sleeve 140 is threadedly engaged with the screw 130, the screw sleeve 140 can move to one side along the screw 130, thereby driving the connecting frame 150 and... The clamping assembly 200 and the conveyor belt are conveyed simultaneously. While the conveyor belt is being conveyed and clamped, the centrifugal fan 340 in the dust removal assembly 300 is activated. With the centrifugal fan 340 in the on state, a negative pressure is created within the connecting box 310. External dust-laden air enters the connecting box 310 through the suction pipe 320 and the conveying pipe 330. It first undergoes preliminary filtration through the metal filter 370 to remove larger particles, and then further filters smaller particles through the HEPA filter 380. The filtered clean air reaches the nozzle 360 ​​through the connecting pipe 350 and is finally ejected from the nozzle 360. The airflow from the nozzle 360 ​​blows away the attached dust and impurities, and combined with the suction from the suction pipe 320, air convection is achieved. This allows dust in the surrounding environment to be quickly absorbed by the suction pipe 320, thus purifying the surrounding air and preventing impurities from adhering and causing friction and scratches during conveying. This ensures the surface quality of the conveyor belt and provides a reliable foundation for subsequent chip processing and testing.

[0027] Example 2

[0028] Please see Figure 1 , Figure 2 and Figure 5 The front and rear ends of the bottom of the connecting frame 150 are fixedly connected to the first sliding sleeve 152. The front and rear ends of the bottom of the inner cavity of the bracket 110 are fixedly connected to the first guide rail 112. The first sliding sleeve 152 is fitted on the surface of the first guide rail 112 and is slidably connected to the surface of the first guide rail 112. The top two sides of the connecting frame 150 are fixedly connected to the second guide rail 151. The bottom two sides of the movable frame 210 are fixedly connected to the second sliding sleeve 211. The second sliding sleeve 211 is fitted on the surface of the second guide rail 151 and is slidably connected to the surface of the second guide rail 151.

[0029] When the first reduction motor 120 in the conveying assembly 100 drives the screw 130 to rotate, causing the screw sleeve 140 and the connecting frame 150 to move, the first sliding sleeve 152 slides along the first guide rail 112. This structure can limit the direction of movement of the connecting frame 150, prevent it from deviating or rotating during movement, and ensure that the connecting frame 150 can only move in a straight line along the axis of the screw 130. This ensures the stability of the clamping assembly 200 and the material belt during the conveying process, allowing the material belt to be accurately conveyed to each station. In the clamping assembly 200, the meshing transmission between the gear 260 and the toothed plate 240 causes the second sliding sleeve 211 to slide along the second guide rail 151 when the movable frame 210 moves, providing precise guidance for the movement of the movable frame 210 and ensuring the straightness and accuracy of the movement of the movable frame 210. This allows the clamping plate 220 to accurately clamp the material belt and can precisely adjust the clamping position as needed to meet the clamping requirements of different specifications of material belts.

[0030] Example 3

[0031] Please see Figure 1 and Figure 3 The top of the bracket 110 is movably connected to the sliding roller 111 via a bearing. Supports are provided around the bottom of the bracket 110. One side of the connecting box 310 is fixedly connected to the front of the front movable frame 210. The bottom of the suction pipe 320 is fixedly connected to the top of the front movable frame 210. The bottom of the spray pipe 360 ​​is fixedly connected to the top of the rear movable frame 210.

[0032] During the conveying process, the sliding roller 111 can rotate freely. When the conveyor belt is placed on its surface and clamped for conveying, the rotation of the sliding roller 111 not only supports the bottom of the conveyor belt but also greatly reduces the friction between the conveyor belts. This allows the conveyor belt to move more smoothly during conveying. Supports are provided around the bottom of the bracket 110, providing a stable support foundation for the entire mechanism. These supports evenly distribute the weight of the mechanism across the work area, ensuring that the mechanism does not sway or tilt during operation, thus enhancing its stability and reliability. This provides a guarantee for the precise conveying and clamping of the conveyor belt. One side of the connecting box 310 is fixedly connected to the front of the front movable frame 210. This connection method allows the dust removal component 300 to move with the front movable frame 210. The movement of the dust removal component 300 ensures that the relative positions of the dust removal component 300 and the clamping component 200 are fixed. During the clamping and conveying of the material belt, the dust removal component 300 can always remain in a suitable position, effectively removing dust from the clamping and conveying area and promptly removing dust and debris that may be attached to the clamping component 200 or the area around the material belt. The suction pipe 320, as an important channel for sucking up dusty air in the dust removal component 300, is fixedly connected to the front movable frame 210 and can accurately suck up dusty air in the clamping and conveying area. The bottom of the nozzle 360 ​​is fixedly connected to the top of the rear movable frame 210, so that the positions of the nozzle 360 ​​and the suction pipe 320 correspond to each other, forming a certain air convection circulation, which facilitates the improvement of dust suction and removal efficiency.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
